                  CORNING INCORPORATED AND SUBSIDIARY COMPANIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)


1.   Basis of Presentation

General

Corning Incorporated and its consolidated  subsidiaries is hereinafter sometimes
referred to as "the Company," "Registrant," "Corning," "we," "our" or "us."

Corning  Incorporated is a world-leading  provider of optical fiber,  cable, and
hardware   and   equipment   products  for  the   telecommunications   industry;
high-performance glass for computer monitors; advanced optical materials for the
semiconductor  industry  and the  scientific  community;  scientific  laboratory
products for the  scientific  community;  ceramic  substrates for the automotive
industry; specialized polymer products for biotechnology applications; and other
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, restructuring
charges,  fixed  asset,  goodwill  and other  asset  impairments,  depreciation,
pension  benefits,  postretirement  benefits other than  pensions,  deferred tax
asset valuation allowance and 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 of 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 for the year ended December 31, 2002.

We  began  recognizing  equity  earnings  from  Dow  Corning  Corporation  ("Dow
Corning") in the first quarter of 2003 since we concluded  that the emergence of
Dow Corning  from  bankruptcy  protection  is probable  based on the  Bankruptcy
Court's  findings on December 11, 2002. See Part II-Other  Information,  Item 1.
Legal Proceedings for a history of this matter.

Certain amounts for 2002 were reclassified to conform with 2003 classifications.

Stock-Based Compensation

We apply Accounting  Principles  Board Opinion No. 25 (APB No. 25),  "Accounting
for Stock Issued to Employees,"  for our  stock-based  compensation  plans.  The
following  table  illustrates  the  effect  on  income  (loss)  from  continuing
operations and earnings  (loss) per share from  continuing  operations if we had
applied  the  fair  value  recognition  provisions  of  Statement  of  Financial
Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based  Compensation,"
to stock-based employee compensation.

New Accounting Standards

In  January  2003,  the  Financial  Accounting  Standards  Board  (FASB)  issued
Interpretation  No.  46,   "Consolidation  of  Variable  Interest  Entities,  an
Interpretation  of  Accounting  Research  Bulletin  No. 51," which  requires all
variable interest entities (VIEs) to be consolidated by the primary beneficiary.
The primary  beneficiary is the entity that holds the majority of the beneficial
interests  in the  VIE.  In  addition,  the  interpretation  expands  disclosure
requirements  for both VIEs that are consolidated as well as VIEs from which the
entity  is the  holder  of a  significant,  but not the  majority  amount of the
beneficial  interests.  We have leased equipment from three  unconsolidated VIEs
for which the sole  purpose is the leasing of  equipment  to us. We assessed the
impact of this interpretation and determined that we are the primary beneficiary
of one existing VIE, and therefore,  began to consolidate  this entity beginning
on July 1, 2003.  The  assets and debt of this  entity at  September  30,  2003,
approximated  $32 million and $34 million,  respectively.  We also evaluated the
impact of this  interpretation  on two other entities and determined that we are
not the  primary  beneficiary  for both  entities.  The assets and debt of these
entities  total $12 million.  The adoption of this  accounting  standard did not
have a material effect on our results of operations or financial position.

The  FASB  also  recently  issued  the  following  pronouncements  which  became
effective July 1, 2003:

     SFAS No. 149,  "Amendment  of SFAS No. 133 on  Derivative  Instruments  and
     Hedging Activities," and
     SFAS  No.  150,   "Accounting  for  Certain   Financial   Instruments  with
     Characteristics of both Liabilities and Equity."

The adoption of these accounting standards did not have a material effect on our
results of operations or financial position.

2.   Restructuring, Impairment and Other Charges and Credits

First Quarter
-------------

In the first  quarter of 2003,  we  recorded  charges for the  shut-down  of the
conventional  video components  business and the optical  switching product line
which were announced on April 15, 2003 and February 13, 2003,  respectively.  We
also  recorded  credits  related to prior years'  restructuring  and  impairment
charges discussed below. A summary of these charges and credits follows:

Conventional video components business

Corning Asahi Video Products Company (conventional video components business, or
CAV),  a 51%  owned  partnership  included  in our  consolidated  results,  is a
manufacturer  of  glass  panels  and  funnels  for  use  in  conventional   tube
televisions and is reported in the Technologies  segment.  In the fourth quarter
of 2002, we impaired certain assets of this business and indicated that we could
be required to record additional  impairment charges, or that we could choose to
exit the business if performance  differed from  expectations.  During the first
quarter,  operating results and cash flows were less than expected,  and certain
customers significantly reduced forecasted orders for the year.

On April 15,  2003,  we  announced  that we had agreed with our partner to cease
production.  We impaired  the  long-lived  assets of this  business to estimated
salvage  value and recorded a charge of $62 million ($19 million  after-tax  and
minority interest). In connection with the cessation of operations, the partners
have reached agreement on the shared funding of CAV's obligations.






Optical Switching

We recorded a charge of $17 million ($11 million after-tax)  associated with the
discontinuance   of  the  optical   switching   product  line  in  the  photonic
technologies  business due to the downturn in the  telecommunications  industry.
The charge included $13 million for employee separation costs and $4 million for
asset impairments related to equipment.

Impairment of Cost Investments

In the first quarter, we recorded a $5 million ($3 million after-tax) charge for
other  than   temporary   declines   in   certain   cost   investments   in  the
Telecommunications segment.

Credits

During the first  quarter,  we reversed  $33  million  ($21  million  after-tax)
related to revised cost estimates of existing  restructuring plans, of which $24
million  related to  employee  separation  and exit  costs  which were less than
estimated,  while $9 million  related to proceeds  in excess of assumed  salvage
values for assets that were previously impaired.

Second Quarter
--------------

In the second quarter of 2003, we recorded  restructuring,  impairment and other
charges of $125 million ($62 million after-tax and minority interest), offset by
credits  related  to prior  years'  restructuring  charges of $76  million  ($59
million after-tax), resulting in a net pre-tax charge of $49 million ($3 million
after-tax and minority interest).  These charges primarily relate to the exit of
the  conventional  video  components  business  and  the  photonic  technologies
business.  The charges also reflect certain  restructuring  actions taken during
the second quarter of 2003 relating to our other businesses.  A summary of these
charges and credits follows:

Conventional Video Components

In the second quarter of 2003, we recorded a restructuring charge of $54 million
($15 million after-tax and minority  interest).  The charge included $18 million
for employee  separation  costs,  $19 million for exit costs and $17 million for
curtailments related to pension and postretirement health care benefits.

In June,  CAV  announced  that it had  signed  a  definitive  agreement  to sell
tangible assets to Henan Anyang CPT Glass Bulb Group, Electronic Glass Co., Ltd.
(Henan  Anyang),  located  in China.  The  proceeds  from this sale may offset a
significant  portion of the cash spending on  restructuring.  We recognized a $5
million  gain  in  the  third   quarter  of  2003  as   described   under  Third
Quarter-Credits below. The sale is expected to be completed in the first half of
2004 at which time we  anticipate  recognizing  the  remainder  of the  original
estimated gain of approximately  $40 million ($13 million after-tax and minority
interest).  We expect  the  restructuring  costs to require  $45  million to $60
million in cash spending.  In addition, we concluded that this business does not
meet the requirements for discontinued  operations treatment under SFAS No. 144,
"Accounting for the Impairment or Disposal of Long-Lived Assets."

Photonic Technologies

In the second  quarter of 2003, we recorded a charge of $33 million ($22 million
after-tax) related to the exit of the photonic technologies business. The charge
included $7 million for employee  separation  costs, $14 million for exit costs,
$7 million for curtailments  related to pension and postretirement  benefits and
$5 million to impair the remaining assets.

Also in the second quarter, we increased the deferred tax valuation allowance by
$21 million as we do not expect to realize certain  deferred tax assets in Italy
related to the photonic technologies  business.  This charge is reflected in the
statement of operations under "Benefit for income taxes."

Finally, we impaired $7 million of equity investments in this business that will
be abandoned as part of the exit from the business.  This charge is reflected in
the statement of operations under, "Equity in earnings of associated  companies,
net of impairments."






Other

We also recorded $38 million of restructuring  and impairment  charges primarily
related to the  telecommunications  businesses and  administrative  staffs.  The
charge  included  $17  million for  employee  separation  costs,  $2 million for
curtailments related to pension and postretirement  benefits and $19 million for
impairments for assets held for sale or abandonment.

Credits

In the second quarter of 2003, we recorded a $76 million ($59 million after-tax)
credit related to prior years'  restructuring and impairment charges,  primarily
in the Telecommunications segment. The reversals included $27 million related to
employee separation costs which were less than estimated, $25 million related to
a  decision  to change  the  restructuring  plans  and not exit a small  cabling
business and $24 million related to proceeds in excess of assumed salvage values
for  assets  that were  previously  impaired  and  certain  assets we decided to
retain.

Third Quarter
-------------

In the third quarter of 2003, we recorded  restructuring,  impairment  and other
charges of $16 million ($13 million after-tax), offset by credits of $26 million
($21 million after-tax and minority interest), resulting in a net pre-tax credit
of $10 million ($8 million after-tax and minority interest).  A summary of these
charges and credits follow:

Photonic Technologies

On July 31,  2003,  we  completed  the  sale of  certain  photonic  technologies
business  assets to Avanex  Corporation  ("Avanex")  in exchange  for 21 million
restricted  shares of Avanex common stock,  which we valued at approximately $53
million.  These shares are restricted  from sale for  approximately  one year at
which point the  restrictions  are lifted at intervals  beginning  July 2004 and
ending October 2005. As the shares become  unrestricted,  we will mark-to-market
the shares through other comprehensive income as available-for-sale  securities.
The Avanex  restricted  shares are reflected as a cost  investment  and recorded
under "Investments" in our consolidated balance sheet. The transaction generated
a loss on sale of $13  million  ($9  million  after-tax)  and  resulted in a $21
million  reduction  of our  goodwill.  See Note 7. In  accordance  with the sale
agreement,  Avanex acquired assets related to the optical amplifier  facility in
Erwin, NY and the optical  component plant in Milan,  Italy. We also paid Avanex
$22 million in cash.  Approximately  400 employees of the photonic  technologies
business became employees of Avanex in the third quarter.

In the third  quarter of 2003,  we  recorded a charge of $3 million  ($4 million
after-tax)  related  to the  exit  of the  photonic  technologies  business  for
employee  separation costs. The after-tax amount included a $2 million write-off
related to a state net operating loss.

We expect to close our pump  laser  facility  in  Bedford,  MA by the end of the
year. Pursuant to a separate  arrangement with Avanex, we are manufacturing pump
lasers for sale to Avanex during the fourth quarter of 2003.  This activity will
be completed and the facility closed by December 31, 2003.

Credits

In the third quarter of 2003, we reversed $20 million ($18 million after-tax) of
restructuring reserves related to prior years' restructuring charges,  primarily
in the Telecommunications segment. The reversals included $10 million related to
employee separation costs which were less than estimated,  $6 million related to
exit costs which were less than estimated and $4 million  related to proceeds in
excess of assumed  salvage values for assets that were  previously  impaired and
certain assets  management  decided to retain as abandoned  factories were being
dismantled.  Approximately  $5  million  of the  reduced  exit costs will not be
incurred due to the Avanex transaction.






In addition to the above, we also recorded the following:

-    a $5 million ($2 million after-tax and minority interest) credit related to
     assets  from CAV that were  previously  impaired  but  later  sold to Henan
     Anyang, and

-    a $1 million gain on the sale of  previously-impaired  cost  investments in
     the Telecommunications segment that were sold in the third quarter.

The current  restructuring  reserve continues to be evaluated as plans are being
executed.  As a result,  there may be additional  charges or reversals in future
periods. In addition,  since the restructuring program is an aggregation of many
individual  plans  currently  being  executed,  actual costs have  differed from
estimated amounts.

The  following  table  illustrates  the  charges,  credits  and  balances of the
restructuring  reserves as of and for the nine months ended  September  30, 2003

expected to be paid by December 31,  2003.  Cash  payments for  employee-related
costs will be  substantially  completed  by  mid-2004,  while  payments for exit
activities will be substantially completed by 2005.

During the third quarter,  we undertook  actions to reduce our costs,  primarily
related  to the  Telecommunications  segment  and  our  corporate  research  and
administrative staffs.

Restructuring Charges

The third quarter  restructuring  charge of $58 million  included $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
entailed   the   elimination   of   approximately   1,000   positions   in   the
Telecommunications  segment and  corporate  research and  administrative  staffs
organizations.

Impairment of Plant and Equipment

We  recorded a $67  million  charge 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.

See Restructuring, Impairment and Other Charges and Credits in our MD&A.

3.   Asbestos Settlement

On  March  28,  2003,  we  announced  that we had  reached  agreement  with  the
representatives  of asbestos  claimants  for the  settlement  of all current and
future   non-premises   asbestos  claims  against  us  and  Pittsburgh   Corning
Corporation (PCC), which might arise from PCC products or operations.

The agreement is expected to be incorporated into a settlement fund as part of a
reorganization  plan  for  PCC.  The  plan  will  be  submitted  to the  federal
bankruptcy  court in  Pittsburgh  for  approval,  and is  subject to a number of
contingencies,  including  a  favorable  vote  by 75  percent  of  the  asbestos
claimants voting on the PCC reorganization  plan. We will make our contributions
to the settlement trust under the agreement after the plan is approved,  becomes
effective and no longer subject to appeal.  The approval  process could take one
year or longer.

Our settlement will require when the plan becomes effective, the contribution of
our equity interest in PCC, our one-half  equity interest in Pittsburgh  Corning
Europe N.V.  (PCE), a Belgian  corporation,  and 25 million shares of our common
stock.  The  common  stock will be  marked-to-market  each  quarter  until it is
contributed to the settlement trust, thus resulting in adjustments to income and
the settlement liability as appropriate.  We will also make cash payments with a
current  value of $134  million  over  six  years  beginning  in June  2005.  In
addition,  we will assign insurance  policy proceeds from our primary  insurance
and a portion of our excess  insurance as part of the settlement.  We recorded a
charge of $298 million ($192 million after-tax) in the first quarter of 2003. In
the third  quarter,  we recorded an additional  $51 million  charge ($31 million
after-tax) to  mark-to-market  the value of our common  stock.  We have recorded
total charges of $388 million ($247 million after-tax) to reflect the settlement
and to  mark-to-market  the value of our common  stock for the nine months ended
September 30, 2003. The carrying value of our stock in PCE and the fair value as
of  September  30,  2003,  of 25 million  shares of our  common  stock have been
reflected in current liabilities.  The remaining $134 million,  representing the
net  present  value of the cash  payments,  discounted  at 5.5%,  is recorded in
noncurrent liabilities. See Part II-Other Information, Item 1. Legal Proceedings
for a history of this matter.







4.   Gain on Repurchases of Debt, Net

During the nine months ended  September  30, 2003 and 2002, we  repurchased  and
retired a significant portion of our zero coupon convertible  debentures through
a combination of open market purchases, debt for equity exchanges and a modified
Dutch tender offer.  The following table  summarizes the activity related to our
zero coupon convertible debentures (dollars in millions):

(a)  Net of the write-off of unamortized issuance and deal costs.

In the first quarter of 2003, we issued 6.5 million  shares of common stock from
treasury  in  exchange  for  55,000  debentures  with an  accreted  value of $43
million.  In accordance  with SFAS No. 84,  "Induced  Conversions of Convertible
Debt," we  recognized a charge of $34 million  reflecting  the fair value of the
incremental  shares issued beyond those required by the terms of the debentures.
The increase in equity due to the issuance of shares from treasury stock was $77
million. This transaction is reflected in the table above.

The balance of zero coupon convertible debentures was as follows:

--------------------------------------------------------------------------------

Zero coupon convertibles         $     470                    $   1,606
--------------------------------------------------------------------------------

Additionally  in the third quarter of 2003, we  repurchased  and retired  60,000
euro notes with a book  value of 60 million  euros for cash of 63 million  euros
(including  accrued  interest) or $70 million.  We recorded a loss of $1 million
($1 million after-tax) on the transaction in the third quarter.

5.   Discontinued Operations

We completed the sale of the  precision  lens business to 3M Company in December
2002. The  transaction  was treated as a discontinued  operation  under SFAS No.
144. Summarized selected financial  information for the discontinued  operations
related to the precision lens business was as follows (in millions):

------------------------------------------------------------------------------------------------------------------------------------

Amortized  intangible  assets are  primarily  related to the  Telecommunications
segment.

Amortization expense related to these intangible assets is expected to be in the
range of approximately $20 million to $35 million annually from 2003 to 2007.







8.   Product Warranty Liability

Provisions for estimated  expenses related to product warranties are made at the
time the  products  are sold using  historical  experience  as a  prediction  of
expected  settlements.  Reserves  are  adjusted  when  experience  indicates  an
expected  settlement  will differ from initial  estimates.  Our reserves  relate
primarily to the  Telecommunications  segment.  Reserves for warranty  items are
included in other accrued  liabilities.  A reconciliation  of the changes in the
product warranty  liability during the nine months ended September 30, 2003, was
as follows (in millions):

9.   Commitments and Contingencies

In 2003, we adopted the initial  recognition and measurement  provisions of FASB
Interpretation  No.  45  (FIN  45).  We do  not  routinely  provide  significant
third-party  guarantees  and,  as a result,  this  interpretation  has not had a
material  effect  on our  financial  statements.  The  initial  recognition  and
measurement  provisions  of FIN 45 are  applicable  on a  prospective  basis  to
guarantees issued or modified after December 31, 2002.

We provide financial guarantees and incur contingent  liabilities in the form of
purchase price adjustments related to attainment of milestones, stand-by letters
of credit and performance  bonds.  These guarantees have various terms, and none
of these guarantees are individually significant. We have also agreed to provide
a  credit  facility  related  to Dow  Corning  as  discussed  in  Note 10 to the
Consolidated  Financial Statements in our 2002 Form 10-K. The funding of the Dow
Corning  $150  million  credit  facility is subject to events  connected  to the
Bankruptcy  Plan as  described in Note 10. As of  September  30,  2003,  we were
contingently  liable  for the  items  described  above  totaling  $433  million,
compared  with $535  million at  December  31,  2002.  We believe a  significant
majority of these  guarantees  and  contingent  liabilities  will expire without
being funded.

From time to time, we are subject to  uncertainties  and  litigation and are not
always able to predict the outcome of these items with assurance.  Various legal
actions,  claims and proceedings are pending against us, including those arising
out  of  alleged  product  defects,  shareholder  matters,  product  warranties,
patents,  asbestos and environmental matters. These issues are discussed in Part
II-Other Information, Item 1. Legal Proceedings of this Form 10-Q.

10.  Shareholders' Equity

In July 2003,  we  completed an equity  offering of 45 million  shares of common
stock  generating net proceeds of approximately  $363 million.  We expect to use
the  net  proceeds  of  this   offering  to  reduce  debt  through  open  market
repurchases,  public tender offers or other methods,  and for general  corporate
purposes. We invest the net proceeds in short-term, interest bearing, investment
grade obligations until they are applied as described.

In April 2003,  we completed an equity  offering of 50 million  shares of common
stock  generating net proceeds of  approximately  $267 million.  We used the net
proceeds of this  offering and  approximately  $356 million of existing  cash to
reduce  debt  through a public  tender  offer in the  second  quarter of 2003 as
discussed in Note 4.

13.  Operating Segments

Corning's  reportable  operating  segments  consist  of  Telecommunications  and
Technologies.  We include  the  earnings of equity  affiliates  that are closely
associated with our operating segments in segment results.






We prepared the financial results for the operating  segments on a basis that is
consistent  with  the  manner  in  which we  internally  disaggregate  financial
information  to assist in making  internal  operating  decisions.  We  allocated
certain common expenses among segments differently than we would for stand-alone
financial  information  prepared in accordance with GAAP. These expenses include
interest,  taxes and corporate functions.  This method of preparation may not be
consistent with methods used by other companies.  The accounting policies of our
operating  segments are the same as those applied in the consolidated  financial
statements.


                                                                         Telecom-                      Non-segment/     Consolidated

ITEM 2.
                     Management's Discussion and Analysis of
                     ---------------------------------------
                  Financial Condition and Results of Operations
                  ---------------------------------------------


The following  management's  discussion and analysis of financial  condition and
results of operations  (MDA) should be read in conjunction with the MDA included
in our Annual Report on Form 10-K for the year ended December 31, 2002.

Overview

A strong  performance  from our display  technologies  business coupled with the
realization of cost savings from our restructuring  actions led to profitability
in the third  quarter of 2003 for the first time  since the  initial  quarter of
2001. Our net income for the third quarter of 2003 was $33 million, or $0.02 per
diluted share,  compared to a net loss of $133 million,  or $0.25 per share,  in
the third quarter of 2002. Our Technologies  segment experienced earnings growth
of 60% in the third quarter,  compared to the prior year quarter,  primarily due
to strong  growth in the liquid  crystal  display  glass and  ceramic  substrate
product  lines which was  partially  offset by continued  softness in demand for
high-purity fused silica products.  In addition, we continued to see weakness in
our  Telecommunications  segment as major carriers  continue to withhold capital
spending.

We  completed  the  sale  of the  major  remaining  components  of our  photonic
technologies  business to Avanex  Corporation  ("Avanex") on July 31, 2003,  and
recorded a loss of $13 million ($9 million after-tax).  In addition, we recorded
the following items which were included in our earnings for the third quarter:

..    a  $51  million  ($31  million  after-tax)  mark-to-market  charge  on  the
     settlement liability for Pittsburgh Corning Corporation ("PCC"),
..    a  net  credit  of  $23  million  ($17  million   after-tax  )  related  to
     restructuring, and
..    a credit of $ 1 million for the net gain on debt buybacks.

We also  improved  our  balance  sheet by  completing  an equity  offering of 45
million  shares of our common  stock for  proceeds of $363  million in the third
quarter. We retired  approximately $466 million in debt during the third quarter
to improve  our debt to capital  ratio by five  points.  At the end of the third
quarter our long-term  debt totaled $2.8  billion.  This is the lowest level our
long-term debt has reached since the third quarter of 2000.

We believe  our reduced  debt levels  together  with our  current  $1.4  billion
balance  of cash and  short-term  investments  and $2 billion  revolving  credit
facility provide us with sufficient liquidity for the next several years to fund
operations,  restructuring,  research and development,  capital expenditures and
scheduled debt repayments.

------------------------------------------------------------------------------------------------------------------------------------


Net sales

Consolidated  net sales for the third  quarter of 2003  increased  $10  million,
compared  to sales  reported  in the  prior  year  quarter.  Net  sales  for the
nine-month  period ended  September  30, 2003,  decreased  7%, or $158  million,
compared to the prior year period. Sales for the quarter increased $4 million in
the  Telecommunications   segment  where  significantly  lower  demand  in  most
businesses  was more than offset by an increase in optical fiber and cable.  For
the nine months ended September 30, 2003, sales in  Telecommunications  declined
$199 million as all businesses experienced decreases.  Sales in the Technologies
segment for the third  quarter of 2003  increased  $4  million,  compared to the
third quarter of 2002,  while net sales for the nine months ended  September 30,
2003,  increased  3%, or $38  million,  compared to the prior year  period.  The
increase for both periods was primarily due to strong demand for liquid  crystal
display glass and our ceramic substrate  products,  partially offset by the exit
from our conventional  television glass business and weak demand for high-purity
fused silica.






Gross margin

As a  percentage  of net sales,  gross  margin  improved  12 points in the third
quarter of 2003 to 29%,  compared to the prior year quarter and  improved  seven
points in the nine months  ended  September  30, 2003,  to 27%,  compared to the
prior year period.  The  improvement  in both periods was primarily due to lower
depreciation  and other  fixed  costs  due to the  restructuring  actions  taken
primarily  in the  Telecommunications  segment  in  2002.  Gross  margin  in the
Telecommunications  segment  improved 19 points over the prior year  quarter and
eight points over the prior year nine-month period. The improvements were due to
cost reductions achieved from the 2002 restructuring actions which was partially
offset by downward  pricing  pressure that continued to negatively  impact gross
margins,  primarily in the optical fiber and cable business. Gross margin in the
Technologies segment increased  approximately five points from the third quarter
of 2002 as strong gains in display  technologies and environmental  technologies
were partially offset by weak performance in the semiconductor  business and the
conventional video components business. Gross margin in the Technologies segment
improved four points over the  nine-month  period of 2002.  Improvements  in the
display technologies  business and the environmental  technologies business were
partially  offset by the  write-down  of  inventory  in the  conventional  video
components business and weak performance in the semiconductor business.

Selling, general and administrative expenses

Selling,  general  and  administrative  (SG&A)  expenses  decreased  6%,  or $10
million, in the third quarter of 2003, compared to the prior year quarter, while
SG&A as a percentage of net sales  improved two points,  compared with the third
quarter of 2002.  SG&A  expenses  decreased  16%, or $86  million,  for the nine
months ended September 30, 2003,  compared to the prior year period,  while SG&A
as a percentage  of net sales  improved  two points,  compared to the prior year
period.  The decrease in SG&A for the quarter and nine months reflected the cost
savings which resulted from the restructuring actions that began in 2001.

Research, development and engineering

Research,  development  and engineering  (RD&E)  expenses  decreased 29%, or $33
million, in the third quarter of 2003, compared to the prior year quarter, while
RD&E as a percentage  of net sales,  decreased  five points,  compared  with the
third quarter of 2002.  RD&E expenses  decreased  30%, or $112 million,  for the
nine months ended September 30, 2003,  compared to the prior year period,  while
RD&E as a percentage of net sales  improved  four points,  compared to the prior
year period.  The decrease in RD&E for the quarter and nine months reflected the
cost savings which  resulted from the  restructuring  actions that began in 2001
and the exit of the photonic technologies business.

Restructuring, impairment and other charges and credits

First Quarter
-------------

In the first  quarter of 2003,  we  recorded  charges for the  shut-down  of the
conventional  video components  business and the optical  switching product line
which were announced on April 15, 2003 and February 13, 2003,  respectively.  We
also  recorded  credits  related to prior years'  restructuring  and  impairment
charges discussed below. A summary of these charges and credits follows:

Conventional video components business

Corning Asahi Video Products Company (conventional video components business, or
CAV),  a 51%  owned  partnership  included  in our  consolidated  results,  is a
manufacturer  of  glass  panels  and  funnels  for  use  in  conventional   tube
televisions and is reported in the Technologies  segment.  In the fourth quarter
of 2002, we impaired certain assets of this business and indicated that we could
be required to record additional  impairment charges, or that we could choose to
exit the business if performance  differed from  expectations.  During the first
quarter,  operating results and cash flows were less than expected,  and certain
customers significantly reduced forecasted orders for the year.






On April 15,  2003,  we  announced  that we had agreed with our partner to cease
production.  We impaired  the  long-lived  assets of this  business to estimated
salvage  value and recorded a charge of $62 million ($19 million  after-tax  and
minority interest). In connection with the cessation of operations, the partners
have reached agreement on the shared funding of CAV's obligations.

Optical Switching

We recorded a charge of $17 million ($11 million after-tax)  associated with the
discontinuance   of  the  optical   switching   product  line  in  the  photonic
technologies  business due to the downturn in the  telecommunications  industry.
The charge included $13 million for employee separation costs and $4 million for
asset impairments related to equipment.

Impairment of Cost Investments

In the first quarter, we recorded a $5 million ($3 million after-tax) charge for
other  than   temporary   declines   in   certain   cost   investments   in  the
Telecommunications segment.

Credits

During the first  quarter,  we reversed  $33  million  ($21  million  after-tax)
related to revised cost estimates of existing  restructuring plans, of which $24
million  related to  employee  separation  and exit  costs  which were less than
estimated,  while $9 million  related to proceeds  in excess of assumed  salvage
values for assets that were previously impaired.

Second Quarter
--------------

In the second quarter of 2003, we recorded  restructuring,  impairment and other
charges of $125 million ($62 million after-tax and minority interest), offset by
credits  related  to prior  years'  restructuring  charges of $76  million  ($59
million after-tax), resulting in a net pre-tax charge of $49 million ($3 million
after-tax and minority interest).  These charges primarily relate to the exit of
the  conventional  video  components  business  and  the  photonic  technologies
business.  The charges also reflect certain  restructuring  actions taken during
the second quarter of 2003 relating to our other businesses.  A summary of these
charges and credits follows:

Conventional Video Components

In the second quarter of 2003, we recorded a restructuring charge of $54 million
($15 million after-tax and minority  interest).  The charge included $18 million
for employee  separation  costs,  $19 million for exit costs and $17 million for
curtailments related to pension and postretirement health care benefits.

In June,  CAV  announced  that it had  signed  a  definitive  agreement  to sell
tangible assets to Henan Anyang CPT Glass Bulb Group, Electronic Glass Co., Ltd.
(Henan  Anyang),  located  in China.  The  proceeds  from this sale may offset a
significant  portion of the cash spending on  restructuring.  We recognized a $5
million  gain  in  the  third   quarter  of  2003  as   described   under  Third
Quarter-Credits below. The sale is expected to be completed in the first half of
2004 at which time we  anticipate  recognizing  the  remainder  of the  original
estimated gain of approximately  $40 million ($13 million after-tax and minority
interest).  We expect  the  restructuring  costs to require  $45  million to $60
million in cash spending.  In addition, we concluded that this business does not
meet the requirements for discontinued  operations  treatment under Statement of
Financial Accounting Standards (SFAS) No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets."

Photonic Technologies

In the second  quarter of 2003, we recorded a charge of $33 million ($22 million
after-tax) related to the exit of the photonic technologies business. The charge
included $7 million for employee  separation  costs, $14 million for exit costs,
$7 million for curtailments  related to pension and postretirement  benefits and
$5 million to impair the remaining assets.






Also in the second quarter, we increased the deferred tax valuation allowance by
$21 million as we do not expect to realize certain  deferred tax assets in Italy
related to the photonic technologies  business.  This charge is reflected in the
statement of operations under "Benefit for income taxes."

Finally, we impaired $7 million of equity investments in this business that will
be abandoned as part of the exit from the business.  This charge is reflected in
the statement of operations under, "Equity in earnings of associated  companies,
net of impairments."

Other

We also recorded $38 million of restructuring  and impairment  charges primarily
related to the  telecommunications  businesses and  administrative  staffs.  The
charge  included  $17  million for  employee  separation  costs,  $2 million for
curtailments related to pension and postretirement  benefits and $19 million for
impairments for assets held for sale or abandonment.

Credits

In the second quarter of 2003, we recorded a $76 million ($59 million after-tax)
credit related to prior years'  restructuring and impairment charges,  primarily
in the Telecommunications segment. The reversals included $27 million related to
employee separation costs which were less than estimated, $25 million related to
a  decision  to change  the  restructuring  plans  and not exit a small  cabling
business and $24 million related to proceeds in excess of assumed salvage values
for  assets  that were  previously  impaired  and  certain  assets we decided to
retain.

Third Quarter
-------------

In the third quarter of 2003, we recorded  restructuring,  impairment  and other
charges of $16 million ($13 million after-tax), offset by credits of $26 million
($21 million after-tax and minority interest), resulting in a net pre-tax credit
of $10 million ($8 million after-tax and minority interest).  A summary of these
charges and credits follows:

Photonic Technologies

On July 31,  2003,  we  completed  the  sale of  certain  photonic  technologies
business assets to Avanex in exchange for 21 million restricted shares of Avanex
common stock,  which we valued at  approximately  $53 million.  These shares are
restricted from sale for  approximately one year at which point the restrictions
are lifted at intervals  beginning  July 2004 and ending  October  2005.  As the
shares become  unrestricted,  we will  mark-to-market  the shares  through other
comprehensive  income as  available-for-sale  securities.  The Avanex restricted
shares are reflected as a cost  investment and recorded under  "Investments"  in
our consolidated balance sheet. The transaction  generated a loss on sale of $13
million ($9 million  after-tax)  and resulted in a $21 million  reduction of our
goodwill. In accordance with the sale agreement,  Avanex acquired assets related
to the optical  amplifier  facility in Erwin, NY and the optical component plant
in Milan,  Italy.  We also paid  Avanex $22 million in cash.  Approximately  400
employees of the photonic  technologies  business became  employees of Avanex in
the third quarter.

In the third  quarter of 2003,  we  recorded a charge of $3 million  ($4 million
after-tax)  related  to the  exit  of the  photonic  technologies  business  for
employee  separation costs. The after-tax amount included a $2 million write-off
related to a state net operating loss.

We expect to close our pump  laser  facility  in  Bedford,  MA by the end of the
year. Pursuant to a separate  arrangement with Avanex, we are manufacturing pump
lasers for sale to Avanex during the fourth quarter of 2003.  This activity will
be completed and the facility closed by December 31, 2003.






Credits

In the third quarter of 2003, we reversed $20 million ($18 million after-tax) of
restructuring reserves related to prior years' restructuring charges,  primarily
in the Telecommunications segment. The reversals included $10 million related to
employee separation costs which were less than estimated,  $6 million related to
exit costs which were less than estimated and $4 million  related to proceeds in
excess of assumed  salvage values for assets that were  previously  impaired and
certain assets  management  decided to retain as abandoned  factories were being
dismantled.  Approximately  $5  million  of the  reduced  exit costs will not be
incurred due to the Avanex transaction.

In addition to the above, we also recorded the following:

-    a $5 million ($2 million after-tax and minority interest) credit related to
     assets  from CAV that were  previously  impaired  but  later  sold to Henan
     Anyang, and

-    a $1 million gain on the sale of  previously-impaired  cost  investments in
     the Telecommunications segment that were sold in the third quarter.

The current  restructuring  reserve continues to be evaluated as plans are being
executed.  As a result,  there may be additional  charges or reversals in future
periods. In addition,  since the restructuring program is an aggregation of many
individual  plans  currently  being  executed,  actual costs have  differed from
estimated amounts.

Almost  one-quarter  of the  remaining  $214  million  restructuring  reserve is
expected to be paid by December 31,  2003.  Cash  payments for  employee-related
costs will be  substantially  completed  by  mid-2004,  while  payments for exit
activities will be substantially completed by 2005.

The following table  illustrates the headcount  reduction  amongst U.S.  hourly,
U.S. salaried and non-U.S. positions related to the 2003 plans:

                            ==================================================

--------------------------------------------------------------------------------

As of September 30, 2003,  approximately  6,700 of the 7,100  employees had been
separated  under the 2002 plans and  approximately  1,350 of the 1,800 employees
had been  separated  under the 2003 plans.  We expect the remainder of employees
affected by the 2002  actions to be  separated  by  December  31, 2003 and those
impacted by the 2003 actions to be separated by June 30, 2004.

See Note 2 to the Consolidated Financial Statements.

Operating loss

We  incurred  an  operating  loss of $1  million  in the third  quarter of 2003,
compared to an  operating  loss of $277 million in the prior year  quarter.  The
decrease in the  operating  loss was primarily  due to lower  restructuring  and
impairment  charges,  improvements  in  gross  margin  and  lower  SG&A and RD&E
expenses.  For the nine months ended  September  30, 2003,  our  operating  loss
decreased  $842  million  over the  prior  year  period  primarily  due to lower
restructuring  and impairment  charges,  improvements  in gross margin and lower
SG&A and RD&E expenses.







Asbestos settlement

On  March  28,  2003,  we  announced  that we had  reached  agreement  with  the
representatives  of asbestos  claimants  for the  settlement  of all current and
future  non-premises  asbestos claims against us and PCC, which might arise from
PCC products or operations.

The agreement is expected to be incorporated into a settlement fund as part of a
reorganization  plan  for  PCC.  The  plan  will  be  submitted  to the  federal
bankruptcy  court in  Pittsburgh  for  approval,  and is  subject to a number of
contingencies,  including  a  favorable  vote  by 75  percent  of  the  asbestos
claimants voting on the PCC  reorganization  plan. We will make contributions to
the  settlement  trust under the agreement  after the plan is approved,  becomes
effective and no longer subject to appeal.  The approval  process could take one
year or longer.

Our settlement will require the contribution,  when the plan becomes  effective,
of our equity  interest in PCC,  our  one-half  equity  interest  in  Pittsburgh
Corning Europe N.V. (PCE), a Belgian  corporation,  and 25 million shares of our
common stock. The common stock will be marked-to-market each quarter until it is
contributed to the settlement trust, thus resulting in adjustments to income and
the settlement liability as appropriate.  We will also make cash payments with a
current  value of $134  million  over  six  years  beginning  in June  2005.  In
addition,  we will assign insurance  policy proceeds from our primary  insurance
and a portion of the excess  insurance as part of the settlement.  We recorded a
charge of $298 million ($192 million after-tax) in the first quarter of 2003. In
the third  quarter,  we recorded an additional  $51 million  charge ($31 million
after-tax) to  mark-to-market  the value of our common  stock.  We have recorded
total charges of $388 million ($247 million after-tax) to reflect the settlement
and to  mark-to-market  the value of our common  stock for the nine months ended
September 30, 2003. The carrying value of our stock in PCE and the fair value as
of  September  30,  2003,  of 25 million  shares of our  common  stock have been
reflected in current liabilities.  The remaining $134 million,  representing the
net  present  value of the cash  payments,  discounted  at 5.5%,  is recorded in
noncurrent liabilities. See Part II-Other Information, Item 1. Legal Proceedings
for a history of this matter.

Gain on repurchases of debt, net

During the course of the year we repurchased  and retired a significant  portion
of our zero coupon  convertible  debentures through a combination of open market
purchases,  debt for equity  exchanges and a modified  Dutch tender  offer.  The
following table summarizes the activity  related to our zero coupon  convertible
debentures (dollars in millions):

(a) Net of the write-off of unamortized issuance and deals costs.

In the first quarter of 2003, we issued 6.5 million  shares of common stock from
treasury  in  exchange  for  55,000  debentures  with an  accreted  value of $43
million.  In accordance  with SFAS No. 84,  "Induced  Conversions of Convertible
Debt," we  recognized a charge of $34 million  reflecting  the fair value of the
incremental  shares issued beyond those required by the terms of the debentures.
The increase in equity due to the issuance of shares from treasury stock was $77
million. This transaction is reflected in the table above.

Additionally  in the third quarter of 2003, we  repurchased  and retired  60,000
euro notes with a book  value of 60 million  euros for cash of 63 million  euros
(including accrued interest),  or $70 million.  We recorded a loss of $1 million
($1 million after-tax) on the transaction in the third quarter.






Income taxes

Our benefit for income  taxes and the related  effective  tax benefit  rates for
continuing operations were as follows (in millions):


------------------------------------------------------------------------------------------------------------------------------------
                                                     For the three months                   For the nine months

                                                 ----------------------------           ---------------------------

------------------------------------------------------------------------------------------------------------------------------------
                                                                                              
Benefit for income taxes                         $   (30)          $   (91)              $  (208)         $  (325)
Effective tax benefit rate                          40.5%             31.4%                 31.1%            30.1%
------------------------------------------------------------------------------------------------------------------------------------


The  effective  tax benefit rate for the three months ended  September 30, 2003,
was higher than the U.S. statutory income tax rate of 35% due to the reversal of
restructuring  charges on which a tax benefit was not accrued. The effective tax
benefit rate for the nine months ended  September  30, 2003,  was lower than the
U.S.  statutory  income  tax  rate of 35% due to the  impact  of  restructuring,
impairment and other charges,  asbestos settlement,  debt transactions and state
and local tax benefits.  In the third quarter, our valuation allowance decreased
approximately $36 million from the second quarter,  primarily due to the sale of
optical  component  assets to Avanex.  We recorded  $21 million to increase  our
foreign  deferred tax  valuation  allowance  in the second  quarter as we do not
expect to realize a portion of our  deferred  tax assets in Italy as a result of
our exit from the photonic technologies business. The effective tax benefit rate
without consideration of these items was 33% for the three and nine months ended
September 30, 2003.

The effective tax benefit rate for the three and nine months ended September 30,
2002, was lower than the U.S. statutory income tax rate of 35% due to the impact
of unusable tax credits and nondeductible  expenses and losses.  The tax benefit
rate  in the  third  quarter  of 2002  was  impacted  by  specific  tax  benefit
calculations  for  restructuring,  impairment  and other charges and the gain on
repurchases  of debt.  The effective tax benefit rate without  consideration  of
these items was 33% and 28% for the three and nine months  ended  September  30,
2002, respectively.

Equity earnings, net of impairments

Equity  earnings  increased  79%, or $33 million,  in the third quarter of 2003,
compared to the prior year  quarter,  primarily  due to the  recognition  of $22
million of equity earnings from Dow Corning in 2003 and a strong  performance at
Samsung Corning Precision Glass Company Ltd.  ("Samsung Corning  Precision"),  a
Korean  manufacturer  of  liquid  crystal  display  glass.  These  results  were
partially  offset by a 29%  decrease in equity  earnings  from  Samsung  Corning
Company Ltd. ("Samsung Corning"), a 50 percent owned manufacturer of cathode ray
tube (CRT) glass panels and funnels based in South Korea.  We began  recognizing
equity earnings from Dow Corning in the first quarter of 2003 since we concluded
that the emergence of Dow Corning from  bankruptcy  protection is probable based
on the  Bankruptcy  Court's  findings on December  11, 2002.  See Part  II-Other
Information, Item 1. Legal Proceedings for a history of this matter.

Equity earnings  doubled to $194 million for the nine months ended September 30,
2003, compared to the prior year period, primarily due to the recognition of $64
million  of equity  earnings  from Dow  Corning  and  strong  results at Samsung
Corning  Precision,  partially  offset by an approximate  10% decrease in equity
earnings from Samsung  Corning.  Equity  earnings also included a second quarter
charge of $7 million related to the impairment of several equity  investments in
the Telecommunications  segment related to the exit of the photonic technologies
business.

OPERATING SEGMENTS

Our   reportable   operating   segments   consist  of   Telecommunications   and
Technologies.  We include  the  earnings of equity  affiliates  that are closely
associated with our operating segments in segment results.

We prepared the financial results for the operating  segments on a basis that is
consistent  with  the  manner  in  which we  internally  disaggregate  financial
information to assist in making internal operating decisions.  We have allocated
certain common expenses among segments differently than we would for stand-alone
financial   information  prepared  in  accordance  with  accounting   principles
generally  accepted  in the U.S.  These  expenses  include  interest,  taxes and
corporate  functions.  This method of  preparation  may not be  consistent  with
methods  used by other  companies.  The  accounting  policies  of our  operating
segments are the same as those applied in the consolidated financial statements.

Telecommunications

The  Telecommunications  segment  produces  optical  fiber  and  cable,  optical
hardware  and  equipment,  photonic  modules and  components  for the  worldwide
telecommunications  industry.  In July 2003, we exited the photonic technologies
business.  The  following  table  provides  net  sales  and  other  data for the
Telecommunications segment:

Segment loss before minority interests and
   equity earnings as a percentage of segment sales                  (7.6)%        (52.7)%               (13.2)%        (56.4)%

------------------------------------------------------------------------------------------------------------------------------------







Sales in the segment increased 1%, or $4 million, from the third quarter of 2002
as an increase  in the optical  fiber and cable  business  was almost  offset by
sales declines in all remaining businesses.  For the nine months ended September
30, 2003,  sales in the segment  declined 16%, or $199 million,  compared to the
prior year period.  All  businesses  in the segment  incurred a decline with the
largest in the  optical  fiber and cable  business of $82  million.  The segment
incurred a loss of $27 million in the third  quarter of 2003,  compared to a net
loss of $198 million in the prior year quarter.  The third quarter 2003 loss was
primarily due to  significant  price declines in optical fiber and a decrease in
sales volume in most  businesses  which was partially  offset by cost reductions
from  prior   restructuring   actions  and  a  net  credit  of  $2  million  for
restructuring, impairment and other charges and credits. The credit included $17
million  of  reversals  related to prior  years'  restructuring  and  impairment
charges and a $1 million gain on the  disposition of a previously  impaired cost
investment,  partially  offset  by a $13  million  loss on the  sale of  optical
component  assets to Avanex  and $3  million  for  restructuring  charges.  Each
business also  reported a loss in the third quarter of 2003,  however the losses
were lower than those  incurred in the prior year  quarter.  The decrease in the
loss over the prior year quarter was  primarily  due to cost  savings  resulting
from restructuring  actions and much lower restructuring and impairment charges,
primarily  in the fiber and cable and hardware and  equipment  businesses,  than
those  incurred in the prior year quarter.  For the nine months ended  September
30, 2003,  the segment  incurred a net loss of $151  million,  compared to a net
loss  of  $741  million  in the  prior  year  period,  primarily  due  to  lower
restructuring and impairment charges and cost improvements.

Telecommunications Businesses

The  following  discussion  of  businesses  in  the  Telecommunications  segment
excludes the restructuring and impairment charges and credits to provide clarity
on the underlying business trends.

Sales in the optical fiber and cable business increased 7%, or $14 million,  for
the third quarter of 2003, compared to the prior year quarter.  The increase was
primarily due to a 30% increase in volume for fiber and cable products which was
partially  offset by double  digit price  declines.  For the nine  months  ended
September 30, 2003, sales in the optical fiber and cable business  declined 12%,
or $82 million,  compared to the prior year period.  The decrease was  primarily
due to pricing pressure,  but was partially offset by strong demand in Japan and
China,  particularly in the first quarter.  Sales volume  increased over 20% for
the first nine months of 2003,  compared to the prior year  period.  The optical
fiber and cable business  incurred a loss in the third quarter of 2003,  however
the loss  decreased  over 55%,  compared  to the  prior  year  period,  as price
declines were more than offset by the cost  reductions  from 2002  restructuring
actions.  The business also incurred a loss for the nine months ended  September
30, 2003, but the loss  decreased  over 45%,  compared to the prior year period,
primarily due to cost savings from restructuring actions in 2002.

Sales in the hardware and equipment  business  decreased 1%, or $2 million,  for
the third  quarter of 2003,  compared  to the prior year  quarter.  For the nine
months ended  September 30, 2003,  sales in this  business  decreased 8%, or $32
million, compared to the prior year period. The sales decreases for both periods
were primarily due to the overall lack of capital spending  impacting the entire
telecommunications  industry. The business incurred a loss for the third quarter
of 2003 driven by pricing pressure and lower volumes, however the loss decreased
95% over the loss  incurred  in the prior year  quarter  due to cost  reductions
achieved  from  the  2002  restructuring  actions.  For the  nine  months  ended
September  30, 2003,  the business  incurred a loss due to pricing  pressure and
lower volumes,  however the loss decreased 60% over the prior year period due to
cost savings from restructuring actions.

Sales in the photonic technologies business declined 41%, or $7 million, for the
third quarter of 2003,  compared to the prior year quarter.  For the nine months
ended September 30, 2003,  sales decreased 53%, or $49 million,  compared to the
prior year period.  The sales  declines in both periods  were  primarily  due to
lower sales volume and the sale to Avanex.  The business incurred a loss for the
third quarter and first nine months of 2003, primarily due to dramatically lower
sales volumes.  However,  the 2003 quarter and year-to-date  loss decreased more
than 80%, compared to the losses incurred in the prior year periods. The results
for the third  quarter and nine months of 2003 reflect  cost  savings  resulting
from restructuring  actions taken in 2002. In addition,  the business settled an
open matter with a customer in the third quarter  resulting in the reversal of a
warranty reserve of $6 million.






On July 31, 2003, we completed the sale of a significant portion of the photonic
technologies  business  to  Avanex  in  exchange  for  common  stock  valued  at
approximately $53 million at closing.  See  Restructuring,  Impairment and Other
Charges and Credits and Note 2 to the Consolidated Financial Statements.

Sales in the controls and connectors  business decreased 6%, or $1 million,  for
the third  quarter of 2003,  compared  to the prior year  quarter.  For the nine
months ended September 30, 2003,  sales decreased 40%, or $36 million,  compared
to the prior year period. The sales decline for the quarter was primarily due to
the lack of  capital  spending  in the  telecommunications  industry.  The sales
decline for the nine month period was primarily due to the sale of the appliance
controls   group  in  May  2002  and  the  lack  of  capital   spending  in  the
telecommunications  industry.  The business  incurred a small loss for the third
quarter of 2003,  however the loss decreased over 70% compared to the prior year
quarter.  For the nine months ended September 30, 2003, the business  incurred a
loss,  however the loss decreased  over 85%,  compared to the prior year period,
primarily due to cost savings from restructuring actions taken in 2002.

Technologies

The  Technologies   segment   manufactures   specialized  products  with  unique
properties for customer applications  utilizing glass, glass ceramic and polymer
technologies. Its primary products include liquid crystal display glass for flat
panel  displays,  ceramic  substrates for  automobile  and diesel  applications,
scientific  laboratory  products,  high-purity  fused silica and other  advanced
materials used for the  manufacture of integrated  circuits and glass panels and
funnels for  televisions  and cathode ray tubes. In April 2003, we announced our
planned exit of the conventional video components business and closed operations
on June 30, 2003. As a result,  we will no longer  manufacture  glass panels and
funnels.

Sales in the  Technologies  segment  increased 1%, or $4 million,  for the third
quarter of 2003,  compared to the prior year quarter.  For the nine months ended
September 30, 2003,  sales  increased 3%, or $38 million,  compared to the prior
year  period.   Increased  sales  in  display   technologies  and  environmental
technologies were partially offset by much lower sales in the conventional video
components  business  that we are exiting,  decreased  demand for  semiconductor
materials, the impact of our exit of the lighting products line in late 2002 and
a flat  performance in life sciences.  Segment earnings for the third quarter of
2003 increased 60%, or $26 million,  compared to the prior year quarter. For the
nine months ended  September  30, 2003,  segment  earnings  increased  7%, or $8
million,  compared to the prior year period.  Improved operating  performance in
the third quarter for display  technologies and  environmental  technologies and
stronger  equity  earnings  were  partially   offset  by  the  shutdown  of  the
conventional   video   components   business  and  decreased   earnings  in  the
semiconductor  materials business.  The decrease in earnings for the nine months
ended  September 30, 2003,  was primarily due to  restructuring  and  impairment
charges of $116 million ($34 million  after-tax  and minority  interest) for CAV
and higher spending on RD&E. See Restructuring, Impairment and Other Charges and
Credits and Note 2 to the Consolidated Financial Statements.






Technologies Businesses

The following  discussion of businesses in the Technologies segment excludes the
restructuring  and  impairment  charges  and  credits to provide  clarity on the
underlying business trends.

Sales in the display  technologies  business increased 36%, or $38 million,  for
the third  quarter of 2003,  compared  to the prior year  quarter.  For the nine
months ended September 30, 2003,  sales increased 32%, or $95 million,  compared
to the prior year period.  The increase  for both periods was  primarily  due to
higher  sales volume as  penetration  in the desktop  market for liquid  crystal
display panels  increased.  Volume gains of 45% and 35% for the quarter and nine
months,  respectively,  and favorable  yen exchange  rates for both periods were
partially  offset by price  declines of 5% each for the quarter and nine months.
Earnings in the  business  doubled for the quarter and  nine-month  period ended
September 30, 2003,  compared to the prior year periods.  The increased earnings
were  primarily  due to volume  gains  and  significant  improvements  in equity
earnings from Samsung Corning Precision for the quarter and year-to-date periods
over the prior  year.  The  previously  announced  expansions  of  manufacturing
capacity in Taiwan and Korea are expected to begin production in 2004.

In July 2003,  we  announced  another  expansion of our liquid  crystal  display
manufacturing  facility in Taiwan for $180 million.  The three-phased project is
expected  to be  completed  by the end of 2004 with  production  to begin in the
second quarter of 2004.

Sales in the environmental  technologies business increased 19%, or $19 million,
for the third quarter of 2003, compared to the prior year quarter.  For the nine
months ended September 30, 2003,  sales increased 18%, or $55 million,  compared
to the prior year period.  The increased  sales for both periods were  primarily
due to increased U.S. auto production driven by financing incentives,  favorable
mix of premiums,  favorable exchange rates and higher sales for diesel products.
Earnings in this business  decreased more than 35% and 25% for the third quarter
and nine months of 2003,  respectively,  compared to the prior year periods. The
decreases for both periods were  primarily due to a decrease in equity  earnings
from Cormetech,  a U.S. designer and manufacturer of industrial  catalysts,  and
higher  development  spending for the diesel product line which more than offset
increased sales volume, favorable mix, and manufacturing efficiency gains.

Sales in the life  sciences  business  were flat for the third  quarter and nine
months ended September 30, 2003,  compared to the prior year periods,  primarily
due to weak sales in Europe.  Earnings in the business  decreased more than 20%,
compared  to the prior year  quarter,  and were flat for the nine  months  ended
September 30, 2003, compared to the prior year period, primarily due to improved
manufacturing  efficiencies  and a gain on the  disposition  of a minor  product
line,  that was more  than  offset in the third  quarter  by higher  development
spending.

Sales in the  conventional  video  components  business  decreased  70%,  or $33
million,  for the third quarter of 2003, compared to the prior year quarter. For
the nine months ended  September 30, 2003,  sales decreased 52%, or $68 million,
compared to the prior year period. The sales declines are due to loss of volume,
price declines and our decision to exit the business.  As discussed earlier,  we
ceased  operations  in  this  business  in  the  second  quarter  of  2003.  See
Restructuring,  Impairment  and  Other  Charges  and  Credits  and Note 2 to the
Consolidated  Financial Statements.  Excluding the asset impairment charges, the
loss increased  approximately 8% for the third quarter of 2003,  compared to the
prior  year  period,   primarily  due  to  decreased  sales  volume,   continued
competitive  pricing  pressures and lower equity  earnings.  For the nine months
ended September 30, 2003, the loss was flat compared to the prior year period.






Samsung Corning  reported an approximate 29% decrease in equity earnings for the
third  quarter of 2003,  compared to the prior year  quarter,  primarily  due to
price reductions.  The market for CRT glass experienced a modest recovery in the
third quarter from the second quarter of 2003 and Samsung Corning was successful
in increasing its market share among major industry competitors.  However, there
continues to be an  overcapacity  of glass in the world market that is resulting
in ongoing  downward price  pressure.  Given the maturity of the industry,  this
situation is expected to continue for the foreseeable future. Samsung Corning is
taking action to address its current cost structure and will continue to monitor
the market situation. Although this business is profitable and generates cash we
expect that our equity  earnings and  dividends  from this venture will be lower
than historical levels going forward.  Further,  it is also possible that future
equity  results may include  operating  losses or significant  restructuring  or
fixed asset impairment  charges  recorded by this business.  For the nine months
ended September 30, 2003,  equity  earnings were down over 10%,  compared to the
prior year  period.  Our  investment  in  Samsung  Corning  was $383  million at
September 30, 2003.

Sales in our other technologies  businesses  decreased 29%, or $19 million,  for
the third  quarter of 2003,  compared  to the prior year  quarter.  For the nine
months ended September 30, 2003,  sales decreased 22%, or $44 million,  compared
to the prior year period.  The decrease  for both periods was  primarily  due to
lower sales volume of  high-purity  fused silica  products in the  semiconductor
materials  business as capital spending in the semiconductor  equipment industry
remained  at  relatively  low levels and the exit of the  lighting  business  in
September 2002. The losses in these  businesses  more than doubled,  compared to
the prior year  quarter and more than  tripled,  compared to the prior year nine
months.  The losses were primarily due to  significantly  lower sales volume and
increased spending in development and engineering for calcium fluoride products.
Due to the losses in the semiconductor business we are evaluating the situation.
It is possible this evaluation may result in future restructuring and impairment
charges.

LIQUIDITY AND CAPITAL RESOURCES

Financing Structure

Over the first nine months of 2003,  we  completed  two equity  offerings of our
common stock as follows:

..    45 million shares in July for net proceeds of $363 million, and
..    50 million shares in May for net proceeds of $267 million.

We used the net proceeds of the May  offering and $356 million of existing  cash
to reduce debt through a modified Dutch tender offer  conducted in June. We will
use the net  proceeds of the July  offering to reduce debt  through  open market
repurchases,  public tender offers or other methods,  and for general  corporate
purposes. See Note 10 to the Consolidated Financial Statements.

We repurchased  and retired  approximately  1.5 million zero coupon  convertible
debentures   over  the  nine  month  period  ended   September  30,  2003,   for
approximately  $1.1  billion in cash and 6.5 million  shares of treasury  common
stock. These activities included a modified Dutch tender offer in June. See Note
4 to the Consolidated Financial Statements and Results of Operations for further
detail.  As a result of our debt repurchase  program,  we reduced the balance of
zero coupon convertible debentures as follows:

--------------------------------------------------------------------------------
                               September 30, 2003        December 31, 2002
--------------------------------------------------------------------------------

Zero coupon convertibles           $     470                $   1,606
--------------------------------------------------------------------------------

The  remaining  zero  coupon  convertible  debentures  may be put  back to us on
November 8, 2005,  at $819.54 per  debenture and on November 8, 2010, at $905.29
per debenture.  We have the option of settling this  obligation in cash,  common
stock,  or a combination of both.  From time to time, we may repurchase for cash
or  equity  certain   additional  debt  securities  in  open-market,   privately
negotiated or publicly tendered transactions.






Due to our  sub-investment  grade  rating,  we  continue  to be  precluded  from
accessing  the  short-term  commercial  paper  market and our access to the debt
markets has been and will likely continue to be  constrained.  The terms that we
could receive on new long-term debt issues would likely be consistent with those
generally available to high yield issuers.

As an additional source of funds, we currently have full unrestricted  access to
a $2 billion  revolving  credit  facility with 17 banks,  expiring on August 17,
2005.  As of  September  30,  2003,  there were no  borrowings  under the credit
facility.  The facility  includes one financial  covenant  limiting the ratio of
total debt to total capital,  as defined,  to not greater than 60%. At September
30, 2003 and December 31, 2002, this ratio was 35% and 47%, respectively.

In March 2001, we filed a universal  shelf  registration  statement with the SEC
that  became  effective  in the first  quarter of 2001.  The shelf  permits  the
issuance  of up to $5.0  billion of various  debt and equity  securities.  As of
October 28,  2003,  our  remaining  capacity  under the shelf  registration  was
approximately $2.9 billion.

Capital Spending

Capital  spending totaled $204 million and $279 million in the nine months ended
September 30, 2003 and 2002, respectively.  Our 2003 capital spending program is
expected to be limited to $350  million to $400  million.  We have  committed to
capital  expenditures of $248 million as of September 30, 2003. Capital spending
activity in 2003 primarily  includes expansion in the liquid crystal display and
environmental businesses.

Restructuring

During the nine  months  ended  September  30,  2003,  we made  payments of $170
million related to employee  severance and termination  costs and $31 million in
other exit costs  resulting from  restructuring  actions.  We expect  additional
payments for actions taken in 2001,  2002 and 2003 to approximate $50 million in
the fourth quarter and $100 million in 2004 with the remainder paid beyond 2005.
Cash  payments for  employee-related  costs will be  substantially  completed by
mid-2004,  while payments for exit activities will be substantially completed by
2005.

Key Balance Sheet Data

At September 30, 2003,  cash and  short-term  investments  totaled $1.4 billion,
compared with $2.1 billion at December 31, 2002.  The decrease from December 31,
2002, was primarily due to long-term debt  repayments,  restructuring  payments,
capital expenditures and the use for working capital. These items were partially
offset by the proceeds from the May and July equity offerings and the receipt of
our U.S. Federal tax refund of $191 million.

--------------------------------------------------------------------------------

Our  earnings  for the first nine months of 2003 were not  adequate to cover our
fixed charges (principally interest and related charges on debt), primarily as a
result   of  the   asbestos   settlement   charge,   losses   incurred   in  the
Telecommunications  segment and  restructuring  and  impairment  charges.  It is
likely our full year 2003  earnings  will not be  sufficient  to cover our fixed
charges.

Management Assessment of Liquidity

Our major  source of funding  for the  remainder  of 2003 and beyond will be our
existing  balance  of  cash  and  short-term  investments.  We  believe  we have
sufficient   liquidity   for  the  next  several   years  to  fund   operations,
restructuring,  research  and  development,  capital  expenditures  and to  make
scheduled debt  repayments.  We also believe we have adequate  liquidity to fund
our debt reduction objectives.

Deferred Taxes

In the third quarter our valuation allowance decreased approximately $36 million
from the second quarter,  primarily due to the sale of optical  component assets
to Avanex.  In the second quarter,  we increased our valuation  allowance by $21
million as a result of our exit from the  photonic  technologies  business as we
believe it is more likely than not that we would be unable to recognize  certain
deferred tax assets related to this business in Italy. At September 30, 2003, we
have recorded  gross  deferred tax assets of  approximately  $1.9 billion with a
valuation  allowance of approximately $396 million.  The valuation  allowance is
primarily  attributable to the uncertainty  regarding the realization of certain
foreign tax benefits, net operating losses and tax credits. The net deferred tax
assets of approximately  $1.5 billion consist of a combination of domestic (U.S.
Federal and State & Local) and foreign tax  benefits  for:  (a) items which have
been recognized for financial reporting purposes,  but which will be reported on
tax  returns  to  be  filed  in  the  future,   and  (b)  loss  and  tax  credit
carryforwards. Realization of the domestic portion of the net deferred tax asset
is dependent upon profitable operations in the United States during carryforward
periods of approximately 20 years.  Although realization is not assured, we have
performed the required  assessment of positive and negative  evidence  regarding
the  realization  of the  net  deferred  tax  assets,  in  accordance  with  the
provisions of SFAS No. 109, "Accounting for Income Taxes," and concluded that it
is more likely than not that such assets will be realized.  Should we experience
a significant  negative  deviation  from our current  performance  expectations,
including significant future unannounced restructuring or impairment charges, it
is possible we could be required to record a valuation allowance on a portion or
all of the deferred tax assets.

U.S. Pension Plans

We sponsor defined  benefit  pension plans covering  certain hourly and salaried
employees in the United  States.  At December 31, 2002,  the  projected  benefit
obligation  exceeded the market value of plan assets by $227 million. We are not
required by employee  benefit and tax laws to make  contributions to our pension
plans prior to 2004,  however,  we contributed  $30 million in the first half of
2003 and an  additional  $70  million  in the third  quarter of 2003 to our U.S.
pension plans.






Off Balance Sheet Arrangements

We have leased  equipment from three  unconsolidated  special  purpose  entities
(SPE) for which the sole  purpose is the leasing of  equipment to us. These SPEs
are not consolidated in the 2002 financial  statements since the equity investor
of the SPE has made a substantial investment that is at risk for the life of the
SPE. However, the Financial Accounting Standards Board issued Interpretation 46,
Consolidation of Variable Interest  Entities in January 2003.  Interpretation 46
requires the  consolidation of variable interest entities (VIE's) by the primary
beneficiary.  We assessed the impact of this  interpretation and determined that
we are the  primary  beneficiary  of one  existing  VIE and  therefore  began to
consolidate  this entity  beginning on July 1, 2003. The assets and debt of this
entity  at  September  30,  2003,  approximated  $32  million  and $34  million,
respectively.  We also evaluated the impact of this  interpretation on two other
entities  and  determined  that we are  not the  primary  beneficiary  for  both
entities.  The assets and debt of these entities total $12 million. In addition,
our maximum  loss  exposure as a result of our  involvement  with these VIE's is
approximately $52 million.  This amount represents payments that would be due to
the VIE in the  event  of a total  loss of the  equipment.  We  carry  insurance
coverage  for this risk.  The  adoption  of this  interpretation  did not have a
material effect on our results of operations or financial position.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our  consolidated  financial  statements  are prepared in conformity  with GAAP,
which requires the use of estimates,  judgments and assumptions  that affect the
reported  amount of assets and  liabilities at the date of financial  statements
and the reported amounts of revenues and expenses during the period presented.

We have  identified a number of critical  accounting  estimates.  An  accounting
estimate is considered  critical if: the estimate requires management to develop
assumptions regarding issues that were highly uncertain at the time the estimate
was  developed;  different  estimates  reasonably  could have been  made;  or if
changes in the  estimate  that would  have a  material  effect on our  financial
condition or results of operations are reasonably likely to occur from period to
period.

Our critical accounting estimates relate to the following areas:

..    impairment of goodwill in the telecommunications reporting unit,
..    impairment of assets held for use,
..    restructuring charges and impairments resulting from restructuring assets,
..    valuation allowances for deferred income taxes,
..    probability of litigation outcomes, and
..    pension assumptions.

These critical accounting  estimates that required  management's most difficult,
subjective  or complex  judgments are described in our 2002 Form 10-K and remain
unchanged through the third quarter of 2003.

ENVIRONMENT

We have been named by the  Environmental  Protection  Agency under the Superfund
Act,  or by  state  governments  under  similar  state  laws,  as a  potentially
responsible party for 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 our policy to accrue for the
estimated   liability  related  to  Superfund  sites  and  other   environmental
liabilities  related  to  property  owned  and  operated  by us based on  expert
analysis and continual monitoring by both internal and external consultants.  We
have  accrued   approximately  $20  million  for  the  estimated  liability  for
environmental  cleanup and related  litigation at September 30, 2003. Based upon
the  information  developed  to date,  we believe  that the accrued  amount is a
reasonable  estimate  of  our  estimated  liability  and  that  the  risk  of an
additional loss in an amount materially higher than that accrued is remote.






On August  27,  2003 , the New York  State  Attorney  General's  Office  filed a
complaint in the New York State Supreme Court, Steuben County,  claiming damages
of  approximately $9 million and alleging that Corning and eight other corporate
defendants  are  liable  for  remediation  and  administrative  costs  the State
incurred to address  hazardous  constituents  identified at the landfill site in
Steuben County. The State alleges that Corning and the other defendants used the
landfill for the disposal of industrial  wastes and other  hazardous  substances
from 1978 to 1988. Based upon information developed to date, management believes
there are statute of  limitation  defenses  barring  recovery  under many of the
claims.  Management  believes that the risk of a materially  adverse  verdict is
remote.

FORWARD-LOOKING STATEMENTS

Additional  discussion  of these and  certain  other risks is  contained  in our
Quarterly Report on Form 10-Q for the second quarter of 2003, in our 2002 Annual
Report on Form 10-K and other documents we file with the SEC, including sections
on  "Forward-Looking  Statements,"  "Risk  Factors"  and "Risks  Relating to our
Business."







ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk Disclosures

There have been no material changes to our market risk exposure during the first
nine months of 2003 with an exception  described  below. For a discussion of our
exposure  to  market  risk,  refer  to Item  7A,  Quantitative  and  Qualitative
Disclosures  About Market  Risks,  contained  in our 2002 Annual  Report on Form
10-K.

Interest Rate Risk

In March and April of 2002,  we entered into three  interest rate swaps that are
fair value hedges and  economically  exchanged a notional amount of $275 million
of fixed rate long-term debt to floating rate debt.  Under the terms of the swap
agreements,  we 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.

In  September  2003,  we  terminated  two of the interest  rate swap  agreements
described  above totaling $150 million.  The termination of these swaps resulted
in a $15 million  gain which we will  amortize  to  earnings  as a reduction  of
interest  expense  over  the  remaining  life  of the  debt.  We  recognized  an
insignificant amount of the gain in the third quarter and included the remaining
deferred  gain on our  consolidated  balance sheet under  "Long-term  debt." The
proceeds from the termination of the swap agreement  totaled $17 million and are
classified in the financing section of our consolidated cash flow statement.  As
of September  30, 2003, we have one  remaining  swap  agreement in effect with a
notional amount of $125 million.

It is our policy to  conservatively  manage our  exposure to changes in interest
rates.  Our policy is that total floating and variable rate debt will not exceed
35% of the  total  debt  portfolio  at  anytime.  At  September  30,  2003,  our
consolidated  debt  portfolio  contained   approximately  5%  of  variable  rate
instruments.


ITEM 4.  CONTROLS AND PROCEDURES

(a)  Evaluation of disclosure controls and procedures.

     The company  carried out an evaluation,  under the supervision and with the
     participation of Corning  management,  including  Corning's chief executive
     officer and its chief financial officer, of the effectiveness of the design
     and operation of Corning's  disclosure  controls and procedures (as defined
     in Rule  13a-15(e)  under  the  Securities  and  Exchange  Act of 1934 (the
     "Exchange  Act")) as of quarter ended  September  30, 2003,  the end of the
     period  covered  by this  report.  Based  upon that  evaluation,  the chief
     executive  officer and chief  financial  officer  concluded  that as of the
     evaluation  date,  the company's  disclosure  controls and  procedures  are
     effective to ensure that information required to be disclosed by Corning in
     reports  that it files or  submits  under  the  Exchange  Act is  recorded,
     processed,  summarized  and reported  within the time periods  specified in
     Securities and Exchange Commission rules and forms.

(b)  Changes in internal controls.

     During the quarter ended  September  30, 2003,  there has been no change in
     our internal control over financial reporting (as defined in Rule 13a-15(f)
     under the  Exchange  Act) that has  materially  affected  or is  reasonably
     likely to materially affect, our internal control over financial reporting.








                           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  $20 million for its  estimated
liability for environmental  cleanup and litigation at September 30, 2003. 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.

Old Bath  Landfill  Lawsuit.  On August 27,  2003 , the New York State  Attorney
General's Office filed a complaint in the New York State Supreme Court,  Steuben
County,  claiming  damages of approximately $9 million and alleging that Corning
and  eight  other   corporate   defendants  are  liable  for   remediation   and
administrative  costs the  State  incurred  to  address  hazardous  constituents
identified  at the  landfill  site in Steuben  County.  The State  alleges  that
Corning  and  the  other  defendants  used  the  landfill  for the  disposal  of
industrial  wastes and other hazardous  substances from 1978 to 1988. Based upon
information  developed  to  date,  management  believes  there  are  statute  of
limitation  defenses  barring  recovery  under  many of the  claims.  Management
believes that the risk of a materially adverse verdict is remote.

Schwinger and Stevens  Toxins  Lawsuits.  In April 2002,  Corning was named as a
defendant in two actions,  Schwinger  and  Stevens,  filed in the United  States
District  Court for the Eastern  District of New York,  which  asserted  various
personal  injury  and  property  damage  claims  against a number  of  corporate
defendants.  These claims  allegedly arise from the release of toxic  substances
from a Sylvania nuclear materials processing facility near Hicksville, New York.
Amended  complaints  naming 205 plaintiffs  and seeking  damages in excess of $3
billion  were served in  September  2002.  The sole basis of  liability  against
Corning was plaintiffs' claim that Corning was the successor to Sylvania-Corning
Nuclear  Corporation,  a Delaware  corporation  formed in 1957 and  dissolved in
1960.  Management  intends to vigorously  contest all claims against Corning for
the reason that  Corning is not the  successor to  Sylvania-Corning.  Management
will also defend on the grounds that almost all of the wrongful death claims and
personal injury claims are time-barred. At a status conference in December 2002,
the Court  decided to  "administratively  close" the Schwinger and Stevens cases
and  ordered   plaintiffs'   counsel  to  bring  new  amended   complaints  with
"bellwether" plaintiffs. In these actions, known as Schwinger II and Astuto, the
plaintiffs  have not named  Corning as a  defendant.  Although  it appears  that
plaintiffs may proceed only against the other corporate defendants, the original
Schwinger  and  Stevens  cases  remain  pending  and no order  has been  entered
dismissing  Corning.   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,  which  has  been in  reorganization
proceedings  under  Chapter 11 of the United States  Bankruptcy  Code since May,
1995. Dow Corning filed for bankruptcy protection to address pending and claimed
liabilities arising from breast-implant  product lawsuits.  On November 8, 1998,
Dow Corning and the Tort  Claimants  Committee  jointly  filed a revised Plan of
Reorganization   (Joint  Plan)  which  provided  for  the  settlement  or  other
resolution of implant claims. The Joint Plan included releases for third parties
(including   Corning  and  Dow  Chemical  as   shareholders)   in  exchange  for
contributions  to the Joint  Plan.  By an order dated  November  30,  1999,  the
Bankruptcy  Court  confirmed  the  Joint  Plan,  but  with  certain  limitations
concerning  the third  party  releases  as  reflected  in an  opinion  issued on
December 21, 1999. On November 13, 2000, the U.S. District Court for the Eastern
District of Michigan reversed the Bankruptcy Court's order with respect to these
limitations on the  third-party  releases and confirmed the Joint Plan.  Certain
foreign  claimants,  the U.S.  government,  and  certain  other  tort  claimants
appealed from the District Court's order. 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. The
Plan  proponents  have settled the lien claims of the U.S.  government  for $9.8
million to be paid from the  Settlement  Fund under the Plan.  On  December  11,
2002, the District Court entered further findings and conclusions supporting the
non-debtor  releases.  Certain tort claimants filed appeals to the U.S. Court of
Appeals for the Sixth  Circuit from the  District  Court's  order.  One group of
foreign claimants has settled and dismissed their appeal,  leaving a grouping of
plaintiffs  from  Nevada as the  remaining  appellants.  Management  expects the
appellate process may take another 12 months. 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 Joint 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 arguments on this appeal on May 2,
2002, and has not ruled.  The amount of additional  interest,  costs and fees at
issue is approximately $100 million pre-tax.

In 1995,  Corning fully  reserved its  investment in Dow Corning upon its filing
for bankruptcy and did not recognize  equity earnings from the second quarter of
1995 through the end of 2002. In the first quarter of 2003,  management assessed
the December 11, 2002,  findings by Judge Hood and concluded  that  emergence of
Dow Corning Corporation from bankruptcy  protection is probable.  Management has
concluded that it has adequately  provided for the other than temporary  decline
associated with the bankruptcy.  With the exception of the remote possibility of
a future bankruptcy related charge, Corning considers the difference between the
carrying  value of its investment in Dow Corning and its 50 percent share of Dow
Corning's equity to be permanent.  This difference was $270 million at September
30, 2003.

Corning  resumed  recognition  of equity  earnings from Dow Corning in the first
quarter of 2003.  Corning does not expect to receive  dividends from Dow Corning
in 2003.

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  (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.
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. In June 2003, Corning renewed its
motion for summary  judgment  upon  papers  incorporating  additional  discovery
materials.  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  in lawsuits  alleging  violations of the U.S.
securities  laws in  connection  with  Corning's  November  2000  offering of 30
million  shares  of  common  stock  and $2.7  billion  zero  coupon  convertible
debentures,  due  November  2015.  In  addition,  the Company and the same three
officers and directors were named in lawsuits  alleging  misleading  disclosures
and non-disclosures  that allegedly inflated the price of Corning's common stock
in the period from  September 2000 through July 9, 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 U.S. District Court of the
Western  District of New York entered an order  consolidating  these actions for
all  purposes,  designating  lead  plaintiffs  and lead  counsel,  and directing
service of a consolidated complaint. In February 2003, defendants filed a motion
to dismiss the  complaint  for failure to allege the  requisite  elements of the
claims with particularity. Plaintiffs responded with opposing papers on April 7,
2003.  The  Court  heard  arguments  on May 29 and June 9,  2003,  and  reserved
decision. The Court's scheduling order further 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.
On December 12, 2002,  the Court entered  judgment  dismissing  the claims as to
each of the defendants.  On December 19, 2002, plaintiffs filed a motion to open
the judgment and for leave to file an amended complaint.  This motion was argued
on April 10, 2003. The Court reserved decision on the motion for leave to amend.
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). Over a period
of more than two decades,  PCC and several other  defendants  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 had
insufficient remaining insurance and assets to deal with its alleged current and
future liabilities. More than 100,000 additional claims have been filed with PCC
after its bankruptcy  filing.  At the time PCC filed for bankruptcy  protection,
there were  approximately  12,400 claims pending  against Corning in state court
lawsuits  alleging  various  theories  of  liability  based on exposure to PCC's
asbestos  products.  Corning  has  defended  those  claims  on the  basis of the
separate  corporate status of PCC and the absence of any facts supporting claims
of direct  liability  arising  from  PCC's  asbestos  products.  Corning is also
currently  named in  approximately  10,900  other  cases  (approximately  40,100
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 past  trends in  resolving  these  claims may not be
indicators of future outcomes.

In the  bankruptcy  court,  PCC in April 2000 obtained a preliminary  injunction
against the prosecution of asbestos  actions arising from PCC's products 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 (PCC Plan). The
Injunction  Period was  extended  as to Corning  on  several  occasions  through
September  30, 2002,  and later for a period from  December  23,  2002,  through
January  23,  2003,  and was  reinstated  as of  April  22,  2003,  and will now
continue, pending developments with respect to the PCC Plan as described below.

On May 14, 2002,  PPG announced that it had agreed with certain of its insurance
carriers and  representatives  of current and future  asbestos  claimants on the
terms of a  settlement  arrangement  applicable  to claims  arising  from  PCC's
products. The announced arrangement would permit PPG and certain of its insurers



to make  contributions  of cash over a period of years,  PPG's shares in PCC and
Pittsburgh  Corning  Europe N.V.  (PCE),  a Belgian  corporation,  and an agreed
number of shares of PPG's  common  stock in return for a release and  injunction
channeling claims against PPG into a settlement trust under the PCC Plan.

On March 28, 2003,  Corning  announced  that it had also reached  agreement with
representatives  of  current  and  future  asbestos  claimants  on a  settlement
arrangement  that will be  incorporated  into the PCC Plan.  This  settlement is
subject to a number of  contingencies,  including a favorable vote by 75% of the
asbestos claimants voting on the PCC Plan, and approval by the bankruptcy court.
Corning's  settlement  will  require  the  contribution,  when the Plan  becomes
effective,  of Corning's equity interest in PCC, its one-half equity interest in
PCE, and 25 million shares of Corning common stock.  Corning also will be making
cash payments of $134 million (net present value as of September 30, 2003 in six
installments beginning in June 2005 assuming the Plan is effective. In addition,
Corning will assign policy rights or proceeds  under its primary  insurance from
1962 through 1984, as well as rights or proceeds under certain excess insurance,
most of which falls  within the period  from 1962  through  1973.  In return for
these  contributions,  Corning  expects to receive a release  and an  injunction
channeling  asbestos  claims  against it into a  settlement  trust under the PCC
Plan.

Corning  has  recorded  a charge in the  amount of $298  million  ($192  million
after-tax)  in its results for the period  ending March 31, 2003.  The amount of
the charge for this settlement  will require  adjustment each quarter based upon
movement in Corning's  common stock price prior to contribution of the shares to
the trust. In the third quarter of 2003,  Corning recorded an additional  charge
of $51 million ($31 million after-tax) to reflect the value of the common stock.
Corning has recorded  total charges of $388 million ($247 million  after-tax) to
reflect the settlement and to  mark-to-market  the value of Corning common stock
for the nine months ended September 30, 2003.

Two of  Corning's  primary  insurers  and  several of its excess  insurers  have
commenced  litigation  against the Company for a  declaration  of the rights and
obligations of the parties under insurance  policies,  including rights that may
be affected by the settlement arrangement described above. Corning is vigorously
contesting  these  cases.  Management  is unable to predict  the outcome of this
insurance litigation.

The PCC Plan, a disclosure  statement and various supplement Plan documents were
filed with the Court in the second quarter of 2003. Additional supplemental plan
documents  were filed in mid August 2003.  Management  expects the court to hold
hearings in October 2003 to review the disclosure documents before sending these
materials to creditors for a vote.  The process of  confirmation  is expected to
take six to 12 months from the time the disclosure  statement is approved by the
Court.  Although  the  confirmation  of the PCC Plan is  subject  to a number of
contingencies,  management believes that the asbestos claims against the Company
will be resolved without additional  material impact on the Company's  financial
statements.

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.  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 intentional fraud
claims were dismissed against all non-settling  defendants on February 25, 2003.
On March 19, 2003,  Astrium  appealed all of the Court's  Rulings  regarding the
various  summary  judgment  motions to the Ninth Circuit  Court of Appeals.  The
Circuit Court has stayed the appeal  pending a decision in a case being appealed
to the California  Supreme Court involving similar issues of law. 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.



In November 2002,  American  Motorists  Insurance  Company and Lumbermens Mutual
Casualty  Company  (collectively  AIMCO)  filed a  declaratory  judgment  action
against Corning, as well as Corning NetOptix,  Inc., OFC Corporation and Optical
Filter  Corporation.  This action is in the United States  District Court of the
Central District of California. In the complaint,  AIMCO seeks a ruling that its
duty to defend the insureds in the  underlying  Astrium  action  ceased with the
dismissal of the negligence claims.  AIMCO also seeks reimbursement of more than
12 million dollars spent for defense costs to date.  Corning believes that AIMCO
remains responsible for the continued representation of all insureds and for any
amount  spent on the  defense of the  insureds  to date.  Answers  were filed in
January  2003 on behalf of the  defendants  other than  Corning.  As a result of
Corning's  motion to dismiss,  AIMCO  amended its complaint and Corning filed an
answer.  Discovery in the case has begun.  The parties have agreed that the case
should be  voluntarily  dismissed  without  prejudice  against  refilling by the
plaintiffs at a future date.  Based upon the  information  developed to date and
recognizing  that the outcome of litigation is  uncertain,  management  believes
that there are strong defenses to the  reimbursement  claim and believes it 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  (CIC) with the American  Arbitration  Association  in New York, New
York,  alleging breaches of its contractual duties and partnership  obligations.
Madeco  asserts that it has the right,  under a "Put  Option," to sell shares of
another  company,  Optel  Ltda.,  to CIC  for  approximately  $18  million  plus
interest. Arbitration hearings were completed in late May 2003, and post-hearing
written  submissions  were filed in June 2003.  A final  decision is expected by
December 31,  2003.  Although  management  believes  the  presentation  of CIC's
position was favorable,  it is not able to predict whether the arbitration panel
will reject Madeco's claim.

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 claims for unjust  enrichment  and to have the  contract
canceled  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.  The arbitration panel
has denied  motions by Tellium  and  Astarte  seeking to be  dismissed  from the
arbitration. Tellium has asked the United States District Court for the Southern
District  of New York to reverse the panel's  decision  continuing  Tellium as a
party in the arbitration  period.  That  application is scheduled to be heard on
November 18, 2003. The arbitration hearings are scheduled in January 2004. While
the outcome of arbitration and court  proceedings  concerning  complex contracts
involving  intellectual  property  matters cannot be predicted  with  certainty,
based upon the  information  discovered  to date,  management  believes that the
disputes in arbitration  will be resolved  without  material impact on Corning's
financial statements.

Furukawa  Electric  Company.  On February 3, 2003, The Furukawa Electric Company
filed suit in the Tokyo  District  Court in Japan against  Corning Cable Systems
International  Corporation  (CCS) alleging  infringement of Furukawa's  Japanese
Patent No.  2,023,966  which  relates to  separable  fiber  ribbon units used in
optical  cable.  Furukawa's  complaint  requests  slightly  over (Y)6 billion in
damages  (approximately  $50 million) and an injunction against further sales in
Japan  of  these  fiber  ribbon  units.   CCS  has  denied  the   allegation  of
infringement,  asserted that the patent is invalid,  and is defending vigorously
against this lawsuit. While recognizing that litigation is inherently uncertain,
based upon the  information  developed  to date,  management  believes  that the
claims  against CCS will not have a material  impact on the Company's  financial
statements.

Fitel USA Corp. and OFS Fitel LLC. On February 3, 2003,  Corning filed an action
in federal  district court for the District of Delaware  against Fitel USA Corp.
(Fitel)  and OFS Fitel  LLC (OFS)  asking  the court to  declare a Fitel  patent
invalid,  unenforceable,  and not  infringed  by Corning.  The patent  generally
relates  to  low  water  content  fiber  used  in  coarse  wavelength   division
multiplexing.   Fitel  and  OFS  have   counterclaimed   that  Corning   induced
infringement of the patent.  Corning has denied the allegations of infringement.
Based  upon  the  information   developed  to  date,  management  believes  this
counterclaim  against  Corning will not have a material  impact on its financial
statements.

Chinese  Anti-Dumping  Investigation.  On July 1, 2003, the Chinese  Ministry of
Commerce  announced  an  anti-dumping  investigation  against  manufacturers  of
optical  fiber  based  in the U.S,  Korea  and  Japan,  alleging  that  standard
single-mode  optical  fiber  was  sold in  China  at  lower  prices  than in the



respective  home  country.  The  investigation  is underway,  with a preliminary
determination  anticipated by April 2004 and a final  determination  possible by
July 1, 2004. Corning is defending vigorously and does not believe it engaged in
dumping.  Corning  management  is not  able  to  estimate  the  impact  of  this
proceeding upon its export business to China pending a final  determination  nor
to  express  assurances  regarding  that  final  determination.  Based  upon the
information  developed to date and  recognizing  that the outcome is  uncertain,
management  believes that the investigation  will be resolved without a material
impact on Corning's financial statements.

PicVue  Electronics  Ltd.,  PicVue  OptoElectronics   International,   Inc.  and
Eglasstrek Gmbh. In June 2002, Corning brought an action seeking to restrain the
use of its trade  secrets  and for  copyright  infringement  relating to certain
aspects  of the  fusion  draw  machine  used for liquid  crystal  display  glass
melting.  This  action is pending in the United  States  District  Court for the
Western District of New York against these three named defendants.  The District
Court in July 2003 denied the PicVue motion to dismiss and granted a preliminary
injunction  in favor of  Corning,  subject  to posting a bond in an amount to be
determined.  PicVue,  a  Taiwanese  company,  responded  in  July  2003  with  a
counterclaim  alleging  violations of the antitrust laws and claiming damages of
more than  $120  million  as well as  requesting  trebled  damages.  PicVue  has
appealed the District  Court's ruling and the District Court has deferred ruling
on the bond amount until the  completion  of such appeal.  Recognizing  that the
outcome  of  litigation  is  uncertain,  management  believes  that  the  PicVue
counterclaim  is without merit and that the  likelihood of a materially  adverse
verdict against Corning is remote.

Tyco Electronics  Corporation and Tyco Technology Resources,  Inc. On August 13,
2003, CCS Holdings Inc. (CCS), a Corning subsidiary, filed an action in the U.S.
District  Court  for  the  Middle  District  of  North  Carolina   against  Tyco
Electronics  Corporation and Tyco Technology Resources,  Inc. (Tyco), asking the
court to declare a Tyco patent  invalid  and not  infringed  by CCS.  The patent
generally relates to a type of connector for optical fiber cables.  Prior to the
lawsuit,  Tyco had asserted  that CCS infringed  this patent,  which CCS denied.
Tyco  continued  to  threaten  to sue CCS and CCS took  action  to  resolve  the
dispute.  Recognizing  that the outcome of litigation  is uncertain,  management
believes  this  suit will not have a  material  impact  on  Corning's  financial
statements.

Grand Jury Investigation of Conventional  Cathode Ray Television Glass Business.
In August 2003,  Corning Asahi Video Products  Company ("CAV") was served with a
federal grand jury document  subpoena  related to pricing,  bidding and customer
practices  involving  conventional  cathode ray  television  glass  picture tube
components.  Two employees  each received a related  subpoena.  CAV is a general
partnership,  51% owned by Corning  and 49% owned by Asahi Glass  America,  Inc.
CAV's only manufacturing facility in State College, Pennsylvania recently closed
due to declining sales. CAV is cooperating with the government investigation.

                                  CERTIFICATION
                                  -------------

I, James R. Houghton, certify that:

1.   I have reviewed this quarterly report on Form 10-Q of Corning Incorporated;

2.   Based on my knowledge,  this  quarterly  report does not contain any untrue
     statement of a material fact or omit to state a material fact  necessary to
     make the statements  made, in light of the  circumstances  under which such
     statements  were made, not misleading with respect to the period covered by
     this quarterly report;

3.   Based on my  knowledge,  the  financial  statements,  and  other  financial
     information  included  in this  quarterly  report,  fairly  present  in all
     material respects the financial  condition,  results of operations and cash
     flows of the  registrant  as of, and for,  the  periods  presented  in this
     quarterly report;

4.   The  registrant's  other  certifying  officers  and I are  responsible  for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:

     a)   designed  such  disclosure  controls  and  procedures,  or caused such
          disclosure   controls  and   procedures  to  be  designed   under  our
          supervision,  to ensure  that  material  information  relating  to the
          registrant,  including its consolidated subsidiaries, is made known to
          us by others within those entities,  particularly during the period in
          which this report is being prepared;

     b)   evaluated the  effectiveness of the registrant's  disclosure  controls
          and procedures and presented in this report our conclusions  about the
          effectiveness of the disclosure controls and procedures, as of the end
          of the period covered by this report based on such evaluation; and

     c)   disclosed  in this  report  any  change in the  registrant's  internal
          control over financial reporting that occurred during the registrant's
          most recent fiscal quarter (the registrant's  fourth fiscal quarter in
          the case of an annual  report)  that has  materially  affected,  or is
          reasonably  likely to materially  affect,  the  registrant's  internal
          control over financial reporting; and

5.   The registrant's other certifying  officers and I have disclosed,  based on
     our most recent evaluation of internal control over financial reporting, to
     the registrant's  auditors and the audit committee of registrant's board of
     directors (or persons performing the equivalent function):

                                  -------------


I, James B. Flaws, certify that:

1.   I have reviewed this quarterly report on Form 10-Q of Corning Incorporated;

2.   Based on my knowledge,  this  quarterly  report does not contain any untrue
     statement of a material fact or omit to state a material fact  necessary to
     make the statements  made, in light of the  circumstances  under which such
     statements  were made, not misleading with respect to the period covered by
     this quarterly report;

3.   Based on my  knowledge,  the  financial  statements,  and  other  financial
     information  included  in this  quarterly  report,  fairly  present  in all
     material respects the financial  condition,  results of operations and cash
     flows of the  registrant  as of, and for,  the  periods  presented  in this
     quarterly report;

4.   The  registrant's  other  certifying  officers  and I are  responsible  for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:

     a)   designed  such  disclosure  controls  and  procedures,  or caused such
          disclosure   controls  and   procedures  to  be  designed   under  our
          supervision,  to ensure  that  material  information  relating  to the
          registrant,  including its consolidated subsidiaries, is made known to
          us by others within those entities,  particularly during the period in
          which this report is being prepared;

     b)   evaluated the  effectiveness of the registrant's  disclosure  controls
          and procedures and presented in this report our conclusions  about the
          effectiveness of the disclosure controls and procedures, as of the end
          of the period covered by this report based on such evaluation; and

     c)   disclosed  in this  report  any  change in the  registrant's  internal
          control over financial reporting that occurred during the registrant's
          most recent fiscal quarter (the registrant's  fourth fiscal quarter in
          the case of an annual  report)  that has  materially  affected,  or is
          reasonably  likely to materially  affect,  the  registrant's  internal
          control over financial reporting; and

5.   The registrant's other certifying  officers and I have disclosed,  based on
     our most recent evaluation of internal control over financial reporting, to
     the registrant's  auditors and the audit committee of registrant's board of
     directors (or persons performing the equivalent function):

     a)   all significant  deficiencies and material weaknesses in the design or
          operation  of internal  control  over  financial  reporting  which are
          reasonably  likely to  adversely  affect the  registrant's  ability to
          record, process, summarize and report financial information; and

     b)   any fraud, whether or not material,  that involves management or other
          employees who have a  significant  role in the  registrant's  internal
          control over financial reporting.
