                  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 "the Company," "the  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 and television  screens,  advanced
optical materials for the semiconductor  industry and the scientific  community;
ceramic substrates for the automotive industry; specialized polymer products for
biotechnology applications; and other technologies.

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

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

The results for interim periods are not necessarily  indicative 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.

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

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

Corning  applies  Accounting  Principles  Board  Opinion  No.  25 (APB No.  25),
"Accounting  for Stock Issued to Employees,"  for its  stock-based  compensation
plans.  Compensation  expense is recorded  for awards of shares or share  rights
over the period earned.  Compensation expense of $1 million was recorded for the
three months ended March 31, 2003,  compared  with $1 million in the same period
of 2002.






The following table  illustrates  the effect on loss from continuing  operations
and loss per share if Corning 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.  The estimated
fair  value  of each  Corning  option  is  calculated  using  the  Black-Scholes
option-pricing model.

New Accounting Standards

In January 2003, the Financial Accounting Standards Board 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 variable interest entities that are consolidated as well as VIEs from which
the entity is the holder of a significant  amount of the  beneficial  interests,
but not the majority.  The disclosure  requirements of this  interpretation  are
effective  for all  financial  statements  issued after  January 31,  2003.  The
consolidation  requirements of this interpretation are effective for all periods
beginning after June 15, 2003. Management is still assessing the impacts of this
interpretation,  however,  it is probable  that Corning will be  considered  the
primary  beneficiary of one existing  special purpose entity and therefore would
need to consolidate  this entity  beginning on July 1, 2003. The assets and debt
of this entity at March 31, 2003,  approximates  $34  million.  Corning is still
evaluating the impacts of this  interpretation on two other entities with assets
and liabilities of $12 million.

2.   Restructuring, Impairment and Other Charges and Credits

In the first quarter of 2003,  Corning 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.
Corning also recorded  credits related to the  restructuring  reserve  discussed
below.

Conventional video components business

Corning Asahi Video Products Company (conventional video components business, or
CAV), a 51% owned consolidated subsidiary, 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,  Corning impaired certain
assets  of this  business  and  indicated  that it could be  required  to record
additional  impairment  charges, or that it 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,  Corning  announced  that it had agreed  with its partner to
cease  production.  Corning  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).  Restructuring  costs,  comprised primarily of
pension termination benefits,  severance and exit costs offset in part by a gain
on the curtailment of post employment  benefits,  are expected to be recorded in
the second quarter and total $80 million to $110 million. In connection with the
cessation  of  operations,  the partners  have  reached  agreement on the shared
funding of CAV's obligations. Corning expects the restructuring costs to require
$40 million to $65 million in cash spending.

Optical Switching

Corning 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.  In  addition  to the first  quarter
charges,  we expect to record  charges of $10 million in the second  quarter for
exit costs.

Impairment of Cost Investments

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






Credits

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

The  following  table  illustrates  the  charges,  credits  and  balances of the
restructuring reserves as of March 31, 2003 (in millions):

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

As of March  31,  2002,  approximately  6,200 of the  7,100  employees  had been
separated under the 2002 plans.

3.   Asbestos Settlement

On March 28, 2003,  Corning  announced  that it had reached  agreement  with the
representatives  of asbestos  claimants  for the  settlement  of all current and
future asbestos claims against Corning 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 favorable vote
by 75 percent of the asbestos claimants voting on the PCC  reorganization  plan.
Corning will make its  contributions to the settlement trust under the agreement
after the plan is approved and no longer subject to appeal. The approval process
could take one year or longer.






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
Pittsburgh  Corning  Europe N.V.  (PCE), a Belgian  corporation,  and 25 million
shares of Corning 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.  Corning will
also make cash  payments  with a current  value of $130  million  over six years
beginning  in June 2005.  In  addition,  Corning  will assign  insurance  policy
proceeds  from its primary  insurance  and a portion of its excess  insurance as
part of the settlement.  Corning recorded a charge of $298 million ($192 million
after-tax) in the first quarter.  The carrying  value of Corning's  stock in PCE
and the fair value as of March 31, 2003, of 25 million  shares of Corning common
stock have been  reflected in current  liabilities.  The remaining $130 million,
representing the net present value of the cash payments,  discounted at 5.5%, is
recorded in noncurrent liabilities. See Legal Proceedings, Part II, Item 1 for a
history of this matter.

4.   Gain on Repurchases of Debt, Net of Inducements

During the first quarter of 2003,  Corning  repurchased and retired 298,500 zero
coupon convertible debentures with an accreted value of $231 million in exchange
for  cash of $189  million  in a  series  of  open-market  repurchases.  Corning
recorded a gain of $38 million on these  transactions,  net of the  write-off of
the unamortized  issuance costs.  Also in the first quarter,  Corning issued 6.5
million  shares of common stock from treasury in exchange for 55,000 zero coupon
convertible debentures with an accreted value of $43 million. In accordance with
SFAS No. 84,  "Induced  Conversions of Convertible  Debt," Corning  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.

In total,  Corning  recorded a net gain of $4  million  ($3  million  after-tax)
associated  with  retirements of its zero coupon  convertible  debentures in the
first quarter. As of March 31, 2003, 1,720,044 debentures with an accreted value
of $1.3 billion remain outstanding.

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


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.  Corning's  reserve
relates primarily to its Telecommunications segment. Reserves for warranty items
are included in other current  liabilities.  A reconciliation  of the changes in
the product warranty liability during the three months ended March 31, 2003, was
as follows (in millions):

--------------------------------------------------------------------------------
Balance at December 31, 2002                                      $   64

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

9.   Commitments and Contingencies

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

Corning's  cash  obligations,  commercial  commitments  and  contingencies  were
relatively  unchanged  from those  disclosed in  Corning's  2002 Form 10-K filed
February 20, 2003.






10.  Comprehensive Loss

Comprehensive loss, net of tax, was as follows (in millions):

11.  Loss Per Common Share

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

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

12.  Operating Segments

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

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

     net operating assets.  Consolidated  subsidiaries with independent  capital
     structures do not receive additional allocations of interest expense.
(4)  Many of Corning's  administrative  and staff  functions  are performed on a
     centralized  basis.  Where  practicable,  Corning charges these expenses to
     segments  based upon the extent to which each  business  uses a centralized
     function. Other staff functions, such as corporate finance, human resources
     and legal are allocated to segments, primarily as a percentage of sales.

13.  Subsequent Event

On April 28, 2003,  Corning announced an equity offering of 50 million shares of
common stock generating net proceeds to Corning of  approximately  $267 million.
Corning  expects to use the net  proceeds of this  offering  and $100 million to
$500 million of existing cash to reduce debt by engaging in,  including  without
limitation,  open market  repurchases and tender offers in the second quarter of
2003.

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

Overview

In the first quarter of 2003, our Telecommunications segment did not display any
signs of  meaningful  recovery as major  carriers  continue to withhold  capital
spending.  At the same time our Technologies  segment exhibited modest growth as
the general economy continues to struggle.  During the quarter, we reached major
milestones regarding two of our joint ventures that have been in litigation.  We
reached a settlement in the asbestos  litigation  related to Pittsburgh  Corning
Corporation  (PCC) and we also  began to  include  the  equity  earnings  of Dow
Corning Corporation ("Dow Corning") in our results.

We recorded a net loss from  continuing  operations of $205 million in the first
quarter of 2003, or $0.17 per share, compared to $98 million, or $0.10 per share
in the prior year  quarter.  The loss for the  quarter  was  primarily  due to a
charge of $298  million  ($192  million  after-tax)  related to an  agreement to
settle  asbestos  litigation  as  part of a  reorganization  of  PCC,  which  is
currently in bankruptcy.

Our Telecommunications  segment continued to incur operating losses in the first
quarter,  although  the  loss in 2003  was  less  than  2002,  reflecting  lower
depreciation  and  operating  expenses  as a  result  of  restructuring  actions
completed in 2002. Revenues increased in our Technologies  segment led by growth
in the display technologies business. The operating results of this segment were
reduced by a charge of $62 million ($19 million after-tax and minority interest)
associated  with the  announced  cessation  of the  Corning  Asahi  Video  (CAV)
operations.

In a continuing  effort to  strengthen  our balance sheet we retired zero coupon
convertible  debentures  with an accreted value of $274 million for cash of $189
million and 6.5  million  shares of common  stock and  recorded a net gain of $4
million ($3 million after-tax).

RESULTS OF CONTINUING OPERATIONS

Selected highlights from our results of continuing operations for the first
quarter were as follows (in millions, except per share amounts and percentages):

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







Net sales

Consolidated  net sales for the first three months of 2003 decreased 11%, or $93
million,  from sales  reported in the prior year quarter.  The sales decline was
most  pronounced in the  Telecommunications  segment where  significantly  lower
demand in most  businesses  and price  declines for our optical  fiber and cable
products drove a sales decline in that segment of 24%, or $113 million, compared
to the prior  year  quarter.  Sales in the  Technologies  segment  for the first
quarter of 2003  increased 5%, or $19 million,  compared to the first quarter of
2002,  primarily due to strong demand for liquid  crystal  display glass and our
ceramic substrate products.

Gross margin

As a  percentage  of net  sales,  gross  margin  improved  5 points in the first
quarter of 2003 to 27%,  compared to the prior year quarter.  The improvement is
primarily  due  to  lower   depreciation  and  other  fixed  costs  due  to  the
restructuring  actions taken in the  Telecommunications  segment in 2002.  Gross
margin in the  Telecommunications  segment improved 3 points over the prior year
quarter despite 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  5 points from the first
quarter  of  2002  led  by  the  display   technologies  and  the  environmental
technologies businesses.

Selling, general and administrative expenses

Selling,  general  and  administrative  (SG&A)  expenses  decreased  19%, or $36
million, in the first quarter of 2003, compared to the prior year quarter, while
SG&A as a  percentage  of net sales  improved 2 points  compared  with the first
quarter of 2002.  The decrease in SG&A for the year  reflected  the cost savings
which resulted from the restructuring actions which began in 2001.

Research, development and engineering

Research,  development  and engineering  (RD&E)  expenses  decreased 26%, or $33
million for the first quarter of 2003, compared to the first quarter of 2002. As
a percentage  of net sales,  RD&E  decreased 3 points for the same  period.  The
decrease in expense  and  expense as a  percentage  of net sales  reflected  the
impact of the restructuring actions which began in 2001.

Restructuring, impairment and other charges and credits

In the first  quarter of 2003,  we  recorded  charges for the  shut-down  of our
conventional  video components  business and our optical  switching product line
which were announced on April 15, 2003 and February 13, 2003,  respectively.  We
also recorded credits related to the restructuring  reserve discussed below. See
Note 2 to the consolidated financial statements.

Conventional video components business

Corning Asahi Video Products Company (conventional video components business, or
CAV), a 51% owned consolidated subsidiary, 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 have 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).   Restructuring  costs,   comprised  primarily  of  pension
termination  benefits,  severance and exit costs offset in part by a gain on the
curtailment  of post  employment  benefits  are  expected  to be recorded in the
second  quarter and total $80 million to $110 million.  In  connection  with the
cessation  of  operations,  the partners  have  reached  agreement on the shared
funding of CAV's obligations.  We expect the restructuring  costs to require $40
million to $65 million in cash spending. We expect charges in the second quarter
after tax and minority  interest to approximate  $20 million to $35 million.  We
are  currently  assessing  whether the disposal of this  business  qualifies for
discontinued  operations  treatment  under  SFAS No.  144,  "Accounting  for the
Impairment or Disposal of Long-Lived Assets."

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.  In  addition  to the first  quarter
charges,  we expect to record  charges of $10 million in the second  quarter for
exit costs.

Impairment of Cost Investments

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

Credits

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

The following table  illustrates the headcount  reduction  amongst U.S.  Hourly,
U.S. Salaried and Non-U.S. positions:

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

As of March  31,  2003,  approximately  6,200 of the  7,100  employees  had been
separated under the 2002 plans.

Operating loss

We  incurred an  operating  loss of $105  million in the first  quarter of 2003,
compared  to an  operating  loss of $141  million in 2002.  The  decrease in the
operating loss was primarily due to the  improvements in gross margin,  SG&A and
RD&E expenses  partially offset by restructuring  charges and asset  impairments
totaling $51 million.  As a percentage of net sales, the operating loss improved
3 points over the prior year quarter.

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
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 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 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
Corning  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 $130 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.
The carrying  value of our stock in PCE and the fair value as of March 31, 2003,
of 25 million  shares of Corning  common  stock have been  reflected  in current
liabilities.  The remaining $130 million,  representing the net present value of
the cash  payments,  discounted at 5.5%, is recorded in noncurrent  liabilities.
See Legal Proceedings, Part II, Item 1 for a history of this matter.

Gain on Repurchases of Debt, Net of Inducements

During the first quarter of 2003, we repurchased and retired 298,500 zero coupon
convertible  debentures  with an accreted  value of $231 million in exchange for
cash of $189 million in a series of open-market repurchases.  We recorded a gain
of $38 million on these  transactions,  net of the write-off of the  unamortized
issuance costs. Also in the first quarter,  we issued 6.5 shares of common stock
from treasury in exchange for 55,000 zero coupon convertible  debentures with an
accreted  value of $43  million.  In  accordance  with  Statement  of  Financial
Accounting  Standards (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.

In total, we recorded a net gain of $4 million ($3 million after-tax) associated
with retirements of our zero coupon convertible debentures in the first quarter.
As of March  31,  2003,  1,720,044  debentures  with an  accreted  value of $1.3
billion remain outstanding.

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 ended March 31,
                                   ---------------------------------------
                                          2003                   2002
--------------------------------------------------------------------------------
Benefit for income taxes               $   (144)              $   (50)
Effective tax benefit rate                 (32.4)%               (27.2)%
--------------------------------------------------------------------------------


The effective tax benefit rate for the quarter is lower than the U.S.  statutory
income tax rate of 35% due to the impact of restructuring,  impairment and other
charges,  asbestos settlement and debt transactions.  The effective benefit rate
without consideration of these items was 30% for the quarter.

The  effective tax benefit rate for the first quarter of 2002 was lower than the
U.S.  statutory  income tax rate,  primarily  due to the impact of unusable  tax
credits and nondeductible expenses and losses.






Equity earnings

Equity  earnings  almost  doubled to $59  million in the first  quarter of 2003,
compared to the prior year  quarter,  primarily  due to the  recognition  of $17
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,  which resulted in an $8
million  increase  in equity  earnings  over the prior  year  quarter.  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
Legal Proceedings, Part II, Item 1 for a history of this matter.

Loss from continuing operations

As a result of the above, the loss from continuing operations and per share data
were as follows (in millions, except per share amounts):

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.  The following  table provides net sales and other

Segment net loss as a percentage of segment sales      (17.9)%           (30.5)%
--------------------------------------------------------------------------------

Sales in the segment  declined 24%, or $113  million,  from the first quarter of
2002 as each business in the segment  experienced  a decline in sales,  with the
largest  decline in the optical fiber and cable business.  The segment  incurred
losses of $63  million in the first  quarter of 2003,  compared to a net loss of
$142  million  in the  prior  year  quarter.  The  first  quarter  2003 loss was
primarily due to the  significant  price declines in optical fiber and cable and
the decrease in sales volume in most  businesses.  Each business also reported a
loss in the first quarter of 2003, however the losses were less significant than
those  incurred  in the prior year  quarter.  The  decrease in the loss over the
prior  year  quarter  was  primarily  due  to  cost  reductions  resulting  from
restructuring actions.

The $9 million net credit to restructuring reserves primarily reflects favorable
settlements  in both  proceeds and timing of asset  dispositions.  These reserve
adjustments more than offset the $22 million of charges associated with the exit
of the  optical  switching  product  line and the  impairment  of  certain  cost
investments.

Sales in the optical fiber and cable business declined 24%, or $62 million,  for
the first quarter of 2003, compared to the prior year quarter.  The decrease was
primarily due to price declines for cable and fiber products ranging from 10% to
40% for the quarter,  partially offset by a double digit volume increase.  Sales
benefited  from  unusually  strong  demand  in Japan  and  China,  offset by the
continued weak European and North American markets.  The optical fiber and cable
business  incurred a loss in the quarter,  however the loss  improved  over 30%,
compared to the first quarter of 2002,  as price  declines were more than offset
by the cost reductions from 2002 restructuring actions.

Sales in the hardware and equipment business decreased 10%, or $13 million,  for
the first  quarter  of 2003,  compared  to the  prior  year  quarter.  The sales
decreases were primarily due to the overall lack of capital  spending  impacting
the entire  telecommunications  industry.  The business  incurred a loss for the
quarter driven by lower volumes and pricing pressure,  however the loss improved
14%  over  the  loss  incurred  in the  prior  year  quarter  due  to  the  2002
restructuring actions.

Sales in the photonic  technologies  business declined 50%, or $18 million,  for
the first quarter of 2003, compared to the prior year quarter,  primarily due to
lower  sales  volume as network  buildouts  in the  telecommunications  industry
declined  resulting  in much lower demand for  photonic  products.  The business
incurred a loss for the first  quarter of 2003,  primarily  due to  dramatically
lower sales volumes.  However,  the 2003 quarterly loss decreased more than 70%,
compared  to the loss  incurred  in the prior year  quarter.  The results in the
first  quarter of 2003  reflect cost  reductions  resulting  from  restructuring
actions taken in 2002.

The lack of demand  for  optical  component  products  started in early 2001 and
resulted in restructuring and impairment  charges in 2001, 2002 and in the first
quarter  of  2003.  This  negative  trend  is  expected  to  continue  into  the
foreseeable future.






As we disclosed in our 2002 Form 10-K,  we will  continue to evaluate  strategic
alternatives for this business. While certain product lines are promising in the
event of industry  recovery,  the pace and extent of that recovery is uncertain.
Alternatives  under  consideration  for this  business  include  staying  in the
business with scaled down operations or contract manufacturing, partnering, sale
or   abandonment.   In  February   2003,   we   announced   we  would  stop  the
commercialization  of our optical  switching  product in 2003 and incur  pre-tax
charges of up to $30 million related to the exit representing severance and cash
exit costs.  We estimate that  severance,  exit costs and inventory  write-downs
related to a complete  abandonment of remaining  product lines could approximate
$70 million to $80 million in total pre-tax charges.

Sales in the controls and connectors business decreased 51%, or $20 million, for
the first quarter of 2003, compared to the prior year quarter,  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 was breakeven for the
quarter,  compared to a small loss in the prior year  quarter,  primarily due to
the 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,  glass panels and funnels for  televisions and
cathode ray tubes.

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

Sales in the Technologies segment increased 5%, or $19 million,  compared to the
first quarter of 2002, as increased sales in display technologies, environmental
technologies  and life sciences were partially offset by much lower sales in the
mature   conventional   video   components   business,   decreased   demand  for
semiconductor materials and the impact of our exit of the lighting products line
in late 2002. Segment earnings  decreased 26%, or $9 million,  compared to 2002,
as  improved  operating  performance  in  environmental  technologies,   display
technologies  and the life sciences  business and stronger  equity earnings were
more than offset by the  restructuring and impairment charge of $62 million ($19
million after-tax and minority  interest) for the conventional  video components
business and decreased  earnings in the semiconductor  materials  business.  See
Restructuring, Impairment and Other Charges and Credits.

Sales in the display  technologies  business increased 26%, or $24 million,  for
the first quarter of 2003, compared to the prior year quarter.  The increase was
primarily  due to higher  sales  volume as  penetration  in the  desktop  market
increased.  Volume gains of 20% and favorable yen exchange rates for the current
period were partially  offset by price declines of 6%.  Earnings in the business
increased  over  35%  for the  quarter,  compared  to the  prior  year  quarter,
primarily due to volume gains and a more than 40% improvement in equity earnings
from Samsung Corning Precision.  Both Corning and Samsung Corning Precision have
recently  approved  expansions  of  manufacturing  capacity in Taiwan and Korea,
respectively. These capital projects are expected to begin production in 2004.






Sales in the environmental  technologies business increased 22%, or $21 million,
for the first quarter of 2003, compared to the prior year quarter, primarily due
to increased U.S. auto production,  particularly early in the quarter, driven by
financing  incentives  and strong  growth in Europe and Japan.  Earnings in this
business  improved  28% for the  quarter,  compared  to the prior year  quarter,
primarily due to the increased sales volume,  favorable mix, strong gross margin
improvement and manufacturing gains.

Sales in the life sciences business  increased 4%, or $3 million,  for the first
quarter of 2003,  compared to the prior year  quarter,  primarily  due to strong
growth in most product  lines.  Earnings in the business  increased  50% for the
quarter,  compared  to  the  prior  year  quarter,  primarily  due  to  improved
manufacturing  efficiencies  and a gain on the  disposition  of a minor  product
line.

Sales in the  conventional  video  components  business  decreased  42%,  or $18
million,  for the first  quarter of 2003,  compared  to the prior year  quarter.
Pricing  pressure  is strong in this  market due to  increased  competition.  As
discussed  earlier,  we have decided to cease operations in this business in the
second quarter of 2003.  Excluding the asset  impairment  charges,  the business
earned a small profit for the quarter and was flat  compared to 2002,  primarily
due to improved equity earnings  partially  offset by decreased sales volume and
continued  competitive  pricing  pressures.  Samsung Corning Company Ltd., a 50%
owned manufacturer of glass panels and funnels based in South Korea,  reported a
more  than 20%  increase  in equity  earnings  for the  first  quarter  of 2003,
compared to the prior year quarter.

Sales in our other technologies  businesses  decreased 16%, or $11 million,  for
the first quarter of 2003, compared to the prior year quarter.  The decrease was
led by the exit of the  lighting  business  in  September  2002 and 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 as the industry continues to struggle. The losses in these
businesses more than doubled compared to the prior year quarter. The losses were
primarily  due to  significantly  lower sales volume and  increased  spending in
development and engineering for calcium fluoride products.

LIQUIDITY AND CAPITAL RESOURCES

Sources of Cash Flow and Key First Quarter Activities

On April 28,  2003,  we  announced  an equity  offering of 50 million  shares of
common stock  generating net proceeds to us of  approximately  $267 million.  We
expect to use the net proceeds of this offering and $100 million to $500 million
of  our  existing  cash  to  reduce  debt  by  engaging  in,  including  without
limitation,  open market  repurchases and tender offers in the second quarter of
2003.

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 16 banks,  expiring on August 17,
2005. As of March 31, 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 March 31, 2003 and
December 31, 2002, this ratio was 46% and 47%, respectively.

In March 2001, we filed a universal  shelf  registration  statement with the SEC
that became effective in the first quarter. The shelf permits the issuance of up
to $5.0 billion of various debt and equity securities. As of April 30, 2003, our
remaining capacity under the shelf registration was approximately $3.3 billion.







Uses of Cash and Key First Quarter Activities

In the  first  quarter  of 2003,  we used  cash for  debt  repurchases,  capital
spending and restructuring actions.

During the first quarter of 2003, we repurchased and retired 298,500 zero coupon
convertible  debentures  with an accreted  value of $231 million in exchange for
cash of $189 million in a series of open-market repurchases.  We recorded a gain
of $38 million on these  transactions,  net of the write-off of the  unamortized
issuance  costs.  Also in the first  quarter we issued  6.5  shares of  treasury
common stock in exchange for 55,000 zero coupon  convertible  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.

In total, we recorded a net gain of $4 million ($3 million after-tax) associated
with retirements of our zero coupon convertible debentures in the first quarter.
As of March 31, 2003,  1,720,044  debentures remain  outstanding.  The remaining
debentures  may be put back to  Corning on  November  8,  2005,  at $819.54  per
debenture and on November 8, 2010, at $905.29 per debenture.  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.

Capital spending totaled $55 million and $101 million in the first quarter ended
March 31, 2003 and 2002,  respectively.  Our 2003  capital  spending  program is
expected  to be  limited  to $350  million  to $400  million.  Capital  spending
activity in 2003 is primarily expected to be the planned expansion in the liquid
crystal display and environmental businesses.

During the first  quarter of 2003,  we made  payments of $79 million  related to
employee  severance  and  termination  costs and $15 million in other exit costs
resulting from restructuring  actions. We expect additional payments for actions
taken in 2001, 2002 and 2003 to approximate $200 million in 2003.

Key Balance Sheet Data

At March 31,  2003,  cash and  short-term  investments  totaled  $1.85  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 and
the use of working  capital.  These items were partially offset by significantly
lower  capital  spending and the receipt of our U.S.  Federal tax refund of $191
million.

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

All three rating agencies maintain a Negative Outlook.

Our  sub-investment  grade  credit  rating has, in some  instances,  resulted in
requirements to deposit cash with  counterparties  under performance surety bond
and letter of credit arrangements.  At March 31, 2003, $82 million of restricted
cash was  included in other  long-term  assets.  We expect our  restricted  cash
balance to increase $40 million to $50 million in the second quarter of 2003.

Our first  quarter 2003  earnings  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  impairment  and  restructuring  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  in 2003 will be our  existing  balance  of cash,
short-term  investments  and the  proceeds of the equity  offering  completed in
April 2003.  We expect to use up to $400  million to $800 million of those funds
to retire debt through open market  repurchases or tender offers.  We believe we
have  sufficient  liquidity  for  the  intermediate  term  to  fund  operations,
restructuring,  research and  development and capital  expenditures  and to make
scheduled debt repayments. We may need to raise additional capital to supplement
our cash and  short-term  investments  to further  reduce our  outstanding  debt
obligations,  including  the zero  coupon debt that may be put to us in November
2005.

Deferred Taxes

At March 31, 2003, we have recorded gross  deferred tax assets of  approximately
$1.8 billion with a valuation allowance in excess of $400 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  $1.4 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
carefully  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.







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 Corning.  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 will require the  consolidation of variable interest entities
(VIE) by the primary  beneficiary.  We are still  assessing  the impacts of this
interpretation,  however,  it is probable  that Corning will be  considered  the
primary beneficiary of one existing SPE, and therefore would need to consolidate
this  entity  beginning  on July 1, 2003.  The assets and debt of this entity at
March 31, 2003, approximates $34 million. We are still evaluating the impacts of
this  interpretation  on two other  entities with assets and  liabilities of $12
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.

OUTLOOK

We disclosed in our 2002 Form 10-K that we expect 2003 net sales to  approximate
those   reported  in  2002,   reflecting   a   year-over-year   decline  in  the
Telecommunications  segment and an improvement in the Technologies  segment.  We
now expect sales to decline year-over-year, primarily due to the exit of CAV. We
also expect,  at a minimum,  to  significantly  reduce  operating losses in 2003
versus 2002 as a result of  restructuring  actions in the second half of 2002 in
Telecommunications and an expected strong performance in Technologies.  Our goal
is to  return to  profitability  in 2003  before  consideration  of  litigation,
restructuring and impairment charges or other  non-operating items such as gains
from debt  retirements.  Our goal to return to  profitability  is dependent upon
stabilization  of revenues  and  continued  strength in North  America and world
economies.

For the second  quarter of 2003, we expect sales in the range of $715 million to
$745 million.  We also expect results for the second quarter to be in a range of
a net loss of $0.02 per share to income of $0.01 per share, excluding the impact
of  previously  announced  restructuring  charges  and  any  adjustments  to the
asbestos settlement reserve required by movement in our stock price.

We believe we have  sufficient  liquidity to meet our funding needs. We finished
the quarter with $1.85 billion in cash and short-term  investments,  raised $267
million in an April  equity  offering  and  continue  to have full  access to an
unused revolving credit facility of $2 billion.  Capital spending is expected to
approximate $350 million to $400 million in 2003. The anticipated  spending will
focus  primarily  on the planned  expansion  in the liquid  crystal  display and
environmental businesses.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of financial  statements  requires  management to make estimates
and  assumptions  that affect  amounts  reported  therein.  The  estimates  that
required  management's  most  difficult,  subjective  or complex  judgments  are
described in our 2002 Form 10-K and remain  unchanged  through the first 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  $22  million  for  the  estimated  liability  for
environmental  cleanup and related  litigation at March 31, 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.

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
three months of 2003. 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.


ITEM 4.  CONTROLS AND PROCEDURES

Within the 90-day period prior to the date of the report, Corning carried out an
evaluation,  under the  supervision  and with the  participation  of management,
including  its Chief  Executive  Officer  and Chief  Financial  Officer,  of the
effectiveness of the design and operation of Corning's  disclosure  controls and
procedures pursuant to Exchange Act Rule 13a-14. Based upon the evaluation,  the
Chief  Executive  Officer and Chief Financial  Officer  concluded that Corning's
disclosure  controls  and  procedures  are  effective  to timely  alert  them to
material   information   related  to   Corning   (including   its   consolidated
subsidiaries) required to be included in Corning's Exchange Act filings.

Subsequent to the date of our management's evaluation, there were no significant
changes in our internal  controls or in other  factors that could  significantly
affect  these  controls,   including  any  corrective  actions  with  regard  to
significant deficiencies and material weaknesses.







                           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  $22 million for its  estimated
liability for environmental cleanup and litigation at March 31, 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.

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 agreed to settle the lien claims of the U.S. government for $9.8
million to be paid from the Settlement  Fund under the Plan. This settlement was
approved by the  District  Court in the third  quarter of 2002.  On December 11,
2002, the District Court entered further findings and conclusions supporting the
non-debtor releases. Certain tort claimants have filed a notice of appeal to the
U.S.  Court of Appeals for the Sixth  Circuit from the District  Court's  order.
Management  expects the appellate  process may take another 12 to 16 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
claimed by the commercial  creditors is approximately  $100 million pre-tax more
than Dow Corning believes it should pay.

In 1995,  Corning fully  reserved its  investment in Dow Corning upon its filing
for bankruptcy and has not recognized  equity  earnings since the second quarter
of 1995. Corning has determined that this decline in the value of its investment
in Dow Corning is other than temporary. Management has assessed the December 11,
2002,  findings  by Judge  Hood and  concluded  that  emergence  of Dow  Corning
Corporation  from  bankruptcy  protection  is  probable.   Management  has  also
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 March 31,
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,  Southern
Division  (Michigan  Federal  Court) to which  substantially  all breast implant
cases were transferred in 1997. In the Michigan Federal Court,  Corning is named
as a defendant in  approximately  70 pending  cases  (including  some cases with
multiple  claimants),  in  addition  to the  transferred  Louisiana  cases.  The
Michigan  Federal Court heard Corning's  motion for summary judgment on February
27, 1998, but has not ruled.  Based upon the  information  developed to date and
recognizing  that the outcome of complex  litigation  is  uncertain,  management
believes that the risk of a materially  adverse result in the implant litigation
against  Corning is remote and believes the implant  litigation  against Corning
will be resolved without material impact on Corning's financial statements.

Federal Securities Cases. A federal securities class action lawsuit was filed in
1992 against Corning and certain individual  defendants by a class of purchasers
of Corning stock who allege  misrepresentations  and omissions of material facts
relative to the silicone gel breast implant  business  conducted by Dow Corning.
This  action is pending in the United  States  District  Court for the  Southern
District of New York. The class consists of those purchasers of Corning stock in
the period from June 14, 1989, to January 13, 1992,  who allegedly  purchased at
inflated   prices  due  to  the   non-disclosure   or  concealment  of  material
information.  No amount of damages is specified in the  complaint.  In 1997, the



Court  dismissed the  individual  defendants  from the case.  In December  1998,
Corning filed a motion for summary  judgment  requesting that all claims against
it be dismissed. Plaintiffs requested the opportunity to take depositions before
responding  to the motion for  summary  judgment.  Corning has advised the Court
that it will renew 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 selective 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.  These  lawsuits are pending in the United States
District  Court for the  Western  District of New York.  On August 2, 2002,  the
District  Court entered an order  consolidating  these actions for all purposes,
designating lead plaintiffs and lead counsel,  and directing that a consolidated
complaint be served within sixty days. The  consolidated  amended  complaint was
served at the end of October 2002. In February 2003,  defendants  filed a motion
to dismiss the  complaint  for failure to allege the  requisite  elements of the
claims with particularity.  Plaintiff's  responded with opposing papers on April
7, 2003. Defendants have until May 12, 2003, to serve reply papers, and argument
is set for May 29, 2003. 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. The 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  10,500  other  cases  (approximately  36,500
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 $130 million  (net present  value as of March 31, 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.

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.

Management  expects that the PCC Plan will be filed with the Court in the second
quarter  of  2003.  No  schedule  has  been  set for  voting  on the PCC Plan by
claimants or for the  confirmation  hearings  required for the court to consider
approval of the PCC Plan. The process of  confirmation  is expected to take from
six to twelve months after the PCC Plan is filed.  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.  Formal  discovery
through document production and depositions was completed for fact witnesses and
will continue through January 2003 for experts. In April 2002, the Court granted
motions for summary  judgment by NetOptix  and other  defendants  to dismiss the
negligence  claims,  but  permitted   plaintiffs  to  add  fraud  and  negligent
misrepresentation  claims  against all defendants and a breach of warranty claim
against NetOptix and its subsidiaries.  In October 2002, the Court again granted
defendants'   motions  for  summary   judgment  and   dismissed   the  negligent
misrepresentation  and breach of warranty claims.  The only claims remaining are
claims by the  plaintiff  for  intentional  fraud  against all  defendants.  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. We anticipate that the Ninth Circuit will establish a briefing
schedule in the very near future.  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.  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 approximately $4
million dollars spent for defense costs through November 2002.  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.  Corning
has moved to dismiss  all claims  filed  against it as it was not a party to the
underlying  Astrium  action.  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 for $4 million.



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
to Madeco." Madeco asserts that it has the right,  under a "Put Option," to sell
shares of another  company to CIC for  approximately  $18  million.  Among other
things,  Madeco requested "no less than $20 million to compensate Madeco for the
breach of its rights under the Put Option,  plus  additional  damages  caused by
Corning's  failure  to  perform  under  the  Investment  Agreement  and  related
contracts." The arbitration panel has been convened and the arbitration hearings
are scheduled for late May 2003.  Based upon the  information  developed to date
and  recognizing  that the  outcome  of  arbitration  is  uncertain,  management
believes that the risk of a materially adverse verdict is remote.

Astarte/Tellium. In July of 2002, Corning filed a demand for binding arbitration
between  Corning and Astarte Fiber Networks Inc.;  Tellium,  Inc.; AFN, LLC; and
their related parties.  The arbitration  concerns a contract relating to certain
patents and patent applications  previously owned by Astarte and now held by AFN
and  Tellium,  Astarte's  successor.  Corning's  demand  includes  a  claim  for
approximately $38 million from those parties due to material  misrepresentations
and fraud, as well as a claim to have the contract 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. While the outcome of arbitration  proceedings concerning complex
contracts  involving  intellectual  property  matters  cannot be predicted  with
certainty,  based upon the information  discovered to date,  management believes
that Corning's claims are well founded.  Management expects that the disputes in
arbitration  will be resolved  without  material  negative  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  CCS  International
Corporation  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  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  has  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 the Company's
financial statements.
