                  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;
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,  in-process
research and development, restructuring charges, asset and goodwill impairments,
depreciation,  pension and postretirement 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 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

Corning  applies  Accounting  Principles  Board  Opinion  No.  25 (APB No.  25),
"Accounting  for Stock Issued to Employees,"  for its  stock-based  compensation
plans.  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  (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 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. Corning has leased equipment from
three unconsolidated  special purpose entities whose sole purpose is the leasing
of   equipment  to  Corning.   Management   has  assessed  the  impact  of  this
interpretation  and  determined  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 June 30, 2003, approximates $32 million and $34 million, respectively.
Corning  has also  evaluated  the  impacts of this  interpretation  on two other
entities and  determined  that Corning is not the primary  beneficiary  for both
entities.  The assets and debt of these entities total $12 million. The adoption
of this accounting standard will not have a material effect on Corning's results
of operations or financial position.

The FASB also recently issued the following pronouncements:

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

The adoption of these  accounting  standards will not have a material  effect on
Corning's results of operations or financial position.

2.   Restructuring, Impairment and Other Charges and Credits

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

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  prior  years'  restructuring  and
impairment charges 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).   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 $45 million to
$60 million in cash spending.  As the business  winds down,  Corning will assess
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

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.

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.

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

In the second quarter of 2003,  Corning 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 Corning's other businesses.  A summary of
these charges and credits follow:

Conventional Video Components

In the second quarter of 2003,  Corning  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.,  located in China.  The proceeds  from this sale may offset a  significant
portion  of the cash  spending  on  restructuring.  The sale is  expected  to be
completed  in the  second  half  of  2003  at  which  time  Corning  anticipates
recognizing  a gain of  approximately  $40 million  ($13 million  after-tax  and
minority interest).






Photonic Technologies

On May 12, 2003, Corning entered into an agreement to sell a significant portion
of its  photonic  technologies  business  to Avanex  Corporation  ("Avanex")  in
exchange for Avanex common stock.  In connection with this  transaction,  Avanex
will also acquire Alcatel  Optronics and combine its existing  business with the
two  acquisitions  to  strengthen  its  position as a  market-leading  photonics
provider.  When this transaction is completed,  Corning will own 17% of Avanex's
common stock and account for this investment under SFAS No. 115, "Accounting for
Certain  Investments  in Debt and  Equity  Securities,"  as  available-for-sale.
Avanex will acquire  specifically  identified  inventories  and equipment at the
Erwin Park, NY and Milan,  Italy locations.  Corning will pay Avanex $20 million
plus an  undetermined  amount (not to exceed $14 million)  for product  warranty
liabilities  upon  closing of the  transaction  which is  expected  in the third
quarter.  Based upon the Avanex  closing stock price at June 30, 2003, the value
of stock to be  received  by Corning is $85  million.  The net book value of the
assets to be sold to Avanex (including the $20 million of cash to be contributed
to Avanex and a portion of the Telecommunications segment goodwill) approximates
$85 million.  The ultimate  value of Avanex stock  received  will be  determined
using the Avanex  closing stock price at the  transaction  closing date with any
resulting gain or loss being recorded at such time.  See Note 14.

In the second  quarter of 2003,  Corning  recorded a charge of $33 million  ($22
million  after-tax)  related to the exit of the photonics  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,  Corning  increased  the  deferred  tax  valuation
allowance by $21 million as it does not expect to realize  certain  deferred tax
assets in Italy related to the photonics  business.  This charge is reflected in
the statement of operations under "Benefit for income taxes."

Finally, Corning 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

Corning  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

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.

In the second  quarter of 2003,  Corning  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
Corning decided to retain.

restructuring reserves as of June 30, 2003 (in millions):

Almost half of the remaining $285 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.

separated  under the 2002 plans and  approximately  1,100 of the 1,700 employees
had been separated under the 2003 plans.

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

During  the  second  quarter of 2002,  Corning  undertook  actions to reduce its
costs, primarily relating to the Telecommunications segment. The intent to do so
was announced in April 2002.







The  following  table  illustrates  the  charges,  credits  and  balances of the

(a)  Amount is net of $5 million adjustment in employee related costs reflecting
     the difference between estimated and actual costs.
(b)  Amount is net of $5 million  adjustment to assumed  salvage values on asset
     disposals.

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

     Restructuring Charges
     ---------------------
     The $192 million of employee  related  costs  entailed the  elimination  of
     approximately  3,600  positions  in  the  Telecommunications   segment  and
     corporate research and administrative staffs organizations,  of which 1,600
     employees were separated at June 30, 2002.

     Impairment of Plant and Equipment
     ---------------------------------
     Corning  recorded  $224  million to impair plant and  equipment  related to
     facilities  to be shutdown or  disposed,  primarily  in the fiber and cable
     business,   the  photonic   technologies   business  and  certain  research
     facilities.  Of this total charge,  $107 million  pertained to construction
     projects in the fiber and cable  business  abandoned in 2001,  primarily in
     Concord,  NC and Oklahoma City, OK. The impairment  charges were determined
     based on the amount by which the  carrying  value  exceeded the fair market
     value of the asset.

     Loss on Divestiture
     -------------------
     In May 2002,  Corning  completed the sale of its appliance  controls  group
     which  was  included  in  the  controls  and  connectors  business  in  the
     Telecommunications  segment.  In 2002, Corning received cash of $30 million
     and recorded a loss on the sale of  approximately  $16 million ($10 million
     after-tax).

     Impairment of Cost Investments
     ------------------------------
     In the second quarter, Corning recorded a $60 million charge for other than
     temporary  declines in certain cost  investments in the  Telecommunications
     segment. These investments were written off.







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  non-premises  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 $133  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.  In the second  quarter,  Corning  recorded an
additional  $39 million  charge ($24 million  after-tax) to  mark-to-market  the
value of the common stock.  The carrying value of Corning's stock in PCE and the
fair value as of June 30,  2003,  of 25 million  shares of Corning  common stock
have  been  reflected  in  current  liabilities.  The  remaining  $133  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

In June 2003,  Corning  repurchased and retired 834,000 zero coupon  convertible
debentures  with an accreted value of $652 million for cash of $623 million in a
modified Dutch tender offer.  Corning recorded a gain of $13 million ($8 million
after-tax) net of the write-off of the unamortized issuance costs and deal costs
in the second quarter.

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.

The balance of zero coupon convertible debentures remaining as of June 30, 2003,
was 886,044 debentures with an accreted value of $693 million. See Note 14.

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


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 accrued  liabilities.  A reconciliation  of the changes in
the product warranty liability during the six months ended June 30, 2003, was as

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-Other Information, Item 1, Legal Proceedings of this Form 10-Q.

At  June  30,  2003,   Corning's   commitments   and   contingencies   decreased
approximately  $83 million to $452 million from those  disclosed at December 31,
2002, in Corning's 2002 Form 10-K filed February 20, 2003.

10.  Shareholders' Equity

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 used the net proceeds of this offering and approximately $356 million of
existing  cash to reduce debt  through a tender  offer in the second  quarter of
2003 as discussed in Notes 4 and 14.

12.  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):

13.  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.

14. Subsequent Events

In July and August 2003, Corning repurchased and retired or reached an agreement
to repurchase  and retire  246,000 zero coupon  convertible  debentures  with an
accreted  value of $192 million for cash of $187 million.  In addition,  Corning
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.  The
respective  gains and losses from these  transactions  will effectively net to a
gain  under $1  million.  The  balance  of zero  coupon  convertible  debentures
expected to remain when these  transactions  are completed in mid August will be
640,044 with a book value of $501 million.

In July 2003,  Corning  completed  an equity  offering  of 45 million  shares of
common stock generating net proceeds to Corning of  approximately  $363 million.
Corning  expects 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. Corning will invest the net proceeds in short-term, interest
bearing, investment grade obligations until they are applied as described.

On July 31, 2003, Corning completed the sale of certain assets from the photonic
technologies  business  to Avanex in  exchange  for 21 million  shares of Avanex
common  stock.  Corning  also paid Avanex $20 million in cash.  Corning does not
expect  this  transaction  to have a  significant  impact on its results for the
third quarter of 2003. See Note 2.





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

In the second quarter of 2003, our  Telecommunications  segment  continued to be
depressed as major  carriers  continued  to withhold  capital  spending  and, as
expected,  sales to Japan and China declined from the first quarter. At the same
time, our  Technologies  segment  exhibited modest growth as strong gains in the
liquid  crystal  display  and  ceramics  substrate  businesses  were  offset  by
extremely soft demand for high-purity fused silica products and the shut-down of
the conventional video components business.

We announced our decision to exit our photonic  technologies business through an
agreement to sell a significant portion of the business.  The transaction closed
on July 31, 2003. We recorded total second  quarter  charges of $33 million ($22
million  after-tax) to exit this business.  In addition,  we recorded charges of
$54 million ($15 million after-tax and minority interest) related to the closing
of our conventional video components business. We also incurred $38 million ($25
million  after-tax) of  restructuring  and impairment  charges for several other
businesses  and  recorded  credits of $76 million ($59  million  after-tax)  for
revisions  to  prior  years'   restructuring  and  impairment   charges.  A  net
restructuring  and  impairment  charge of $49 million ($3 million  after-tax and
minority   interest)  combined  with  a  $39  million  ($24  million  after-tax)
mark-to-market   adjustment  related  to  our  asbestos   settlement   regarding
Pittsburgh  Corning  Corporation  (PCC) led to a net loss of $22 million for the
second quarter.

We also strengthened our balance sheet in the second quarter by repurchasing and
retiring a significant portion of our zero coupon convertible debentures through
a  tender  offer  in  June.  Additionally,  we  completed  several  open  market
repurchases  of zero coupon  convertible  debentures  and euro notes in July and
August.

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


Net sales

Consolidated  net sales for the  second  quarter  of 2003  decreased  9%, or $75
million,  from  sales  reported  in the prior  year  quarter.  Net sales for the
six-month period ended June 30, 2003,  decreased 10%, or $168 million,  compared
to the  prior  year  period.  The  sales  decrease  for  both  periods  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 21%, or $90  million,  compared to the
prior year quarter and a decline of 23%, or $203 million,  compared to the prior
year six-month period.  Sales in the Technologies segment for the second quarter
of 2003  increased 4%, or $15 million,  compared to the second  quarter of 2002,
while net sales for the six months  ended June 30,  2003,  increased  5%, or $34
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 extremely weak demand for high-purity
fused silica and conventional television funnels.






Gross margin

As a  percentage  of net  sales,  gross  margin  improved 2 points in the second
quarter of 2003 to 24%, compared to the prior year quarter and improved 3 points
in the six  months  ended  June 30,  2003,  to 25%,  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 4 points over both the prior year quarter and six-month period
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 decreased  approximately 1 point from the second quarter of
2002 as strong gains in display technologies and environmental technologies were
more than  offset by weak  performance  in the  semiconductor  business  and the
conventional video components business which recorded a $9 million write-down of
inventory.  Gross margin in the Technologies  segment improved 2 points over the
six-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  21%, or $40
million,  in the second  quarter of 2003,  compared  to the prior year  quarter,
while SG&A as a percentage  of net sales  improved 3 points,  compared  with the
second quarter of 2002. SG&A expenses decreased 20%, or $76 million, for the six
months ended June 30, 2003,  compared to the prior year period,  while SG&A as a
percentage  of net sales  improved 3 points,  compared to the prior year period.
The decrease in SG&A for the quarter and six 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 35%, or $46
million,  in the second  quarter of 2003,  compared  to the prior year  quarter,
while RD&E as a percentage  of net sales,  decreased 5 points  compared with the
second quarter of 2002. RD&E expenses decreased 31%, or $79 million, for the six
months  ended June 30,  2003,  compared to the prior year period while RD&E as a
percentage  of net sales  improved 3 points,  compared to the prior year period.
The decrease in RD&E for the quarter and six months  reflected  the cost savings
which resulted from the restructuring actions that began in 2001.

Restructuring, impairment and other charges and credits

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

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 prior years'  restructuring  and  impairment
charges 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 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. We expect the
restructuring  costs to require $45 million to $60 million in cash spending.  As
the business  winds down,  we will assess  whether the disposal of this business
qualifies for  discontinued  operations  treatment  under Statement of Financial
Accounting  Standards (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.

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

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.

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 our 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 follow:

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.,  located in China.  The proceeds  from this sale may offset a  significant
portion  of the cash  spending  on  restructuring.  The sale is  expected  to be
completed in the second half of 2003 at which time we  anticipate  recognizing a
gain of approximately $40 million ($13 million after-tax and minority interest).






Photonic Technologies

On May 12, 2003, we entered into an agreement with Avanex Corporation ("Avanex")
to sell certain assets related to our photonic technologies business in exchange
for 21 million  shares of Avanex  common  stock.  On July 31, 2003, we completed
this sale. Specifically,  Avanex acquired inventories and equipment at our Erwin
Park, NY and Milan,  Italy  locations.  We also paid Avanex $20 million in cash.
Based upon the Avanex  closing stock price at July 31, 2003,  the value of stock
we received  approximated $85 million.  The net book value of the assets sold to
Avanex (including the $20 million of cash contributed to Avanex and a portion of
the  Telecommunications  segment goodwill)  approximates $85 million.  We do not
expect  this  transaction  to have a  significant  impact on our results for the
third  quarter  of  2003.  See  Notes  2 and  14 to the  consolidated  financial
statements.

In the second  quarter of 2003, we recorded a charge of $33 million ($22 million
after-tax) related to the exit of the photonics 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 photonics 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 of assets held for sale or abandonment.

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.

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.

Hourly, U.S. Salaried and Non-U.S. positions related to the 2003 plans:

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

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

As of June  30,  2003,  approximately  6,600  of the  7,100  employees  had been
separated  under the 2002 plans and  approximately  1,100 of the 1,700 employees
had been separated under the 2003 plans.

Operating loss

We incurred an  operating  loss of $110  million in the second  quarter of 2003,
compared to an  operating  loss of $640 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.  As a percentage of net sales,  the operating loss decreased 62 points
over the prior  year  quarter.  For the six  months  ended  June 30,  2003,  our
operating loss  decreased $566 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.  As a percentage of net sales,  the operating loss
decreased 33 points over the prior year period.

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 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 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 $133  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.  In the
second  quarter,  we recorded an  additional  $39  million  charge ($24  million
after-tax) to  mark-to-market  the value of our common stock. The carrying value
of our stock in PCE and the fair value as of June 30, 2003, of 25 million shares
of our common stock have been  reflected in current  liabilities.  The remaining
$133  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

In June 2003,  we  repurchased  and  retired  834,000  zero  coupon  convertible
debentures  with an accreted value of $652 million for cash of $623 million in a
modified  Dutch  tender  offer.  We  recorded a gain of $13  million ($8 million
after-tax) net of the write-off of the unamortized issuance costs and deal costs
in the second quarter.






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  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," 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.

The balance of zero coupon convertible debentures remaining as of June 30, 2003,
was 886,044  debentures with an accreted value of $693 million.  See Notes 4 and
14 to the consolidated financial statements.

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 six months

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

Benefit for income taxes                         $   (34)         $    (184)            $    (178)        $   (234)

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



The effective tax benefit rate for the three and six months ended June 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  and debt
transactions.  We  recorded  $21 million to increase  our foreign  deferred  tax
valuation allowance 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 37% and
33% for the three and six months ended June 30, 2003, respectively.

The effective tax benefit rate for the three and six months ended June 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 second 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
24% for the three and six months ended June 30, 2002.

Equity earnings, net of impairments

Equity  earnings more than doubled to $60 million in the second quarter of 2003,
compared to the prior year  quarter,  primarily  due to the  recognition  of $25
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. 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 also
included a 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.

Equity  earnings more than doubled to $119 million for the six months ended June
30, 2003,  compared to the prior year period primarily due to the recognition of
$42 million of equity  earnings  from Dow Corning and strong  results at Samsung
Corning Precision.






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.  In May 2003,  we announced  our plans to exit the
photonic technologies business. The following table provides net sales and other
data for the Telecommunications segment:

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








Sales in the segment  declined 21%, or $90 million,  from the second  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 of $34 million.  For the
six months  ended June 30,  2003,  sales in the  segment  declined  23%, or $203
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
$96 million. The segment incurred losses of $61 million in the second quarter of
2003,  compared  to a net loss of $401  million in the prior year  quarter.  The
second quarter 2003 loss was primarily due to the significant  price declines in
optical  fiber and the  decrease in sales volume in most  businesses,  partially
offset by a net credit of $19  million  related to  restructuring.  The  segment
incurred  restructuring  and  impairment  charges  of $56  million in the second
quarter  that were offset by $75 million of  reversals  related to prior  years'
restructuring and impairment charges.  Each business also reported a loss in the
second 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 six months ended June 30, 2003, the segment incurred a net loss
of $124 million compared to a net loss of $543 million in the prior year period,
primarily  due  to  lower   restructuring   and  impairment   charges  and  cost
improvements.

In the second quarter of 2003, we recorded a $75 million credit related to prior
years' restructuring and impairment charges in the  Telecommunications  segment.
The adjustments  included $26 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 assets we decided to retain.

In the first quarter of 2003, we recorded a $31 million  credit related to prior
years'  restructuring  and  impairment  charges  primarily to reflect  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 and resulted in a net credit of $9 million.

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 declined 16%, or $34 million,  for
the second quarter of 2003, compared to the prior year quarter. The decrease was
primarily  due to price  declines  for fiber  products  which  approximated  30%
compared  to the prior  year  quarter  partially  offset by an overall 6% volume
increase for fiber and cable  products.  For the six months ended June 30, 2003,
sales in the optical  fiber and cable  business  declined  21%, or $96  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  almost 20% for the
first six months of 2003  compared to the prior year period.  The optical  fiber
and cable business  incurred a loss in the second  quarter of 2003,  however the
loss  decreased over 40%,  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 six months ended June 30, 2003,  but
the loss decreased over 35% compared to the prior year period,  primarily due to
cost savings from restructuring actions in 2002.

Sales in the hardware and equipment business decreased 11%, or $17 million,  for
the second  quarter of 2003,  compared  to the prior year  quarter.  For the six
months ended June 30, 2003, sales in this business decreased 10%, or $30 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 second quarter
of 2003 driven by pricing pressure and lower volumes, however the loss decreased
70%  over  the  loss  incurred  in the  prior  year  quarter  due  to  the  2002
restructuring  actions.  For the six months  ended June 30,  2003,  the business
incurred a loss due to pricing  pressure  and lower  volumes,  however  the loss
decreased 40% over the prior year period due to cost savings from  restructuring
actions.






Sales in the photonic  technologies  business declined 62%, or $24 million,  for
the second  quarter of 2003,  compared  to the prior year  quarter.  For the six
months ended June 30, 2003, sales decreased 56%, or $42 million, compared to the
prior year period.  The sales  declines in both periods  were  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 second  quarter and first six months of 2003,  primarily
due  to  dramatically  lower  sales  volumes.  However,  the  2003  quarter  and
year-to-date loss decreased more than 70% compared to the losses incurred in the
prior year  periods.  The results for the second  quarter and six months of 2003
reflect cost savings resulting from restructuring actions taken in 2002.

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  $85 million at closing.  The  agreement  allows Avanex to acquire
assets related to the optical  amplifier  facility in Erwin,  NY and the optical
component  plant in Milan,  Italy. As a result of this sale,  approximately  400
employees of photonic  technologies will transition to Avanex. We also expect to
close the pump laser facility in Bedford, MA by the end of the year. See Notes 2
and 14 to the consolidated financial statements.

Sales in the controls and connectors business decreased 45%, or $15 million, for
the second  quarter of 2003,  compared  to the prior year  quarter.  For the six
months ended June 30, 2003, sales decreased 49%, or $35 million, compared to the
prior year period. The sales declines for both periods were 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 second quarter of 2003,  however the loss decreased over 70% compared to
the prior year  quarter.  For the six months ended June 30,  2003,  the business
incurred a loss,  however the loss decreased over 90% compared to the prior year
period, primarily due to the restructuring actions taken in 2002.

A  key  customer  of  the  Telecommunications  segment  is  in  the  process  of
negotiating a new collective bargaining agreement, which expires in August 2003.
Revenues  in the  second  half of 2003  could  be  negatively  affected  if this
customer experiences a prolonged strike.

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. As a result, we will
no longer manufacture glass panels and funnels.

Sales in the Technologies  segment increased 4%, or $15 million,  for the second
quarter of 2003,  compared to the prior year  quarter.  For the six months ended
June 30, 2003,  sales  increased 5%, or $34 million,  compared to the prior year
period.  Increased sales in display technologies and environmental  technologies
were  partially  offset by much  lower  sales in the mature  conventional  video
components business, decreased demand for semiconductor materials, the impact of
our exit of the lighting  products line in late 2002 and a flat  performance  at
life sciences. Segment earnings for the second quarter of 2003 decreased 21%, or
$9 million,  compared to the prior year  quarter.  For the six months ended June
30, 2003, segment earnings decreased 23%, or $18 million,  compared to the prior
year  period.   Improved  operating   performance  in  the  second  quarter  for
environmental technologies,  display technologies and the life sciences business
and stronger  equity  earnings  were more than offset by the  restructuring  and
impairment charge of $54 million ($15 million  after-tax and minority  interest)
for the  conventional  video components  business and decreased  earnings in the
semiconductor  materials  business.  The decrease in earnings for the six months
ended June 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 32%, or $33 million,  for
the second  quarter of 2003,  compared  to the prior year  quarter.  For the six
months ended June 30, 2003, sales increased 29%, or $57 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  increased.  Volume gains of
almost 40% and 30% for the quarter and six months,  respectively,  and favorable
yen exchange rates for both periods were  partially  offset by price declines of
5% and 6% for the quarter and six months, respectively. Earnings in the business
almost  doubled for the second  quarter of 2003 and  increased  over 65% for the
six-month  period ended June 30, 2003,  compared to the prior year periods.  The
increased  earnings were primarily due to volume gains and more than 60% and 50%
improvements in equity  earnings from Samsung Corning  Precision for the quarter
and  year-to-date  periods,  respectively,  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 15%, or $15 million,
for the second quarter of 2003, compared to the prior year quarter.  For the six
months ended June 30, 2003, sales increased 18%, or $36 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,  strong growth in
Europe and Japan and higher sales for diesel products. Earnings in this business
decreased  more than 50% and 20% for the second  quarter and six months of 2003,
respectively,  compared to the prior year  periods,  primarily due to a loss for
the  current  quarter  and  year-to-date  at  Cormetech,  a  U.S.  designer  and
manufacturer of industrial catalysts, and higher spending for the diesel product
line  which  more  than  offset  increased  sales  volume,  favorable  mix,  and
manufacturing efficiency gains.

Revenues  in the second  half of 2003 could be  negatively  affected  if certain
domestic auto  manufacturers  experience a prolonged strike during the course of
the 2003 labor negotiations scheduled to begin in the third quarter.

Sales in the life sciences business decreased 3%, or $2 million,  for the second
quarter of 2003, compared to the prior year quarter, primarily due to weak sales
in Europe.  For the six months ended June 30, 2003,  sales were  relatively flat
compared to the prior year  period as strong  growth in most  product  lines was
offset by a soft market in Europe.  Earnings in the business decreased more than
20%, compared to the prior year quarter,  and were flat for the six months ended
June 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.






Sales in the  conventional  video  components  business  decreased  41%,  or $17
million, for the second quarter of 2003, compared to the prior year quarter. For
the six  months  ended June 30,  2003,  sales  decreased  42%,  or $35  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
have ceased operations in this business in the second quarter of 2003. Excluding
the asset  impairment  charges,  earnings  decreased  approximately  30% for the
second  quarter of 2003,  compared to the prior year  period,  primarily  due to
decreased sales volume, continued competitive pricing pressures and lower equity
earnings.  Samsung  Corning  Company  Ltd.  ("Samsung  Corning"),  a  50%  owned
manufacturer  of glass  panels and  funnels  based in South  Korea,  reported an
approximate  25%  decrease in equity  earnings  for the second  quarter of 2003,
compared  to the  prior  year  quarter  due to lower  sales  volumes  and  price
reductions.  We are evaluating the situation at Samsung Corning to determine the
cause and duration of the sudden softness in demand as it may impact second half
results.  For the six months  ended June 30,  2003,  equity  earnings  were flat
compared  to the  prior  year  period  as were  the  overall  earnings  for this
business.  As a result of our decision to exit the conventional video components
business,  we will  report the equity  earnings  of Samsung  Corning  separately
beginning in the third quarter.

Sales in our other technologies  businesses  decreased 21%, or $14 million,  for
the second  quarter of 2003,  compared  to the prior year  quarter.  For the six
months ended June 30, 2003, sales decreased 19%, or $25 million, compared to the
prior year period.  The decrease for both periods was  primarily due to 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 tripled compared to the prior year quarter and six months.  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

Financing Structure

In July 2003,  we  completed an equity  offering of 45 million  shares of common
stock generating net proceeds to us of approximately  $363 million.  We will 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 will invest the net  proceeds  in  short-term,  interest  bearing,
investment grade  obligations  until we apply them as described.  See Note 14 to
the consolidated financial statements.

In July and August 2003, we  repurchased  and retired or reached an agreement to
repurchase  and  retire  246,000  zero  coupon  convertible  debentures  with an
accreted  value  of $192  million  for cash of $187  million.  In  addition,  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.  The
respective  gains and losses from these  transactions  will effectively net to a
gain  under $1  million.  The  balance  of zero  coupon  convertible  debentures
expected to remain when these  transactions  are completed in mid August will be
640,044  with a book  value of $501  million.  See  Note 14 to the  consolidated
financial statements.

In June 2003,  we  repurchased  and  retired  834,000  zero  coupon  convertible
debentures  with an accreted value of $652 million for cash of $623 million in a
modified  Dutch  tender  offer.  We  recorded a gain of $13  million ($8 million
after-tax),  net of the  write-off of the  unamortized  issuance  costs and deal
costs in the second quarter.

In May 2003,  we  completed  an equity  offering of 50 million  shares of common
stock generating net proceeds to us of approximately  $267 million.  We used the
net  proceeds of this  offering and  approximately  $356 million of our existing
cash to reduce debt through a tender offer discussed above.






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  million  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.

The remaining  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 19 banks,  expiring on August 17,
2005. As of June 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 June 30,  2003 and
December 31, 2002, this ratio was 40% 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
August  6,  2003,  our  remaining  capacity  under the  shelf  registration  was
approximately $2.9 billion.

Capital Spending

Capital  spending  totaled $110 million and $210 million in the six months ended
June 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 $145  million as of June 30,  2003.  Capital  spending
activity in 2003 is primarily expected to be the planned expansion in the liquid
crystal display and environmental businesses.

Restructuring

During the six months  ended June 30,  2003,  we made  payments of $124  million
related to employee  severance  and  termination  costs and $19 million in other
exit costs resulting from restructuring  actions.  We expect additional payments
for actions  taken in 2001,  2002 and 2003 to  approximate  $128 million for the
remainder  of 2003.  Almost half of the  remaining  $285  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.

Key Balance Sheet Data

At June 30, 2003, cash and short-term investments totaled $1.5 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 equity offering and the receipt of our U.S. Federal
tax refund of $191 million.

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

Our six  months  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  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 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 June 30, 2003,  we have recorded
gross  deferred  tax  assets of  approximately  $1.9  billion  with a  valuation
allowance of approximately  $432 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 plan to make 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
will require the  consolidation  of variable  interest  entities  (VIE's) by the
primary  beneficiary.  We have  assessed the impact of this  interpretation  and
determined  that we 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 June 30,  2003,  approximates  $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 $53 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  will not have a
material effect on our results of operations or financial position.

OUTLOOK

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  or  losses  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 third  quarter of 2003,  we expect sales in the range of $740 million to
$765 million.  We believe fiber volumes may grow sequentially in the range of 5%
to 10% based on growth in Japan.  Display  technologies  is also expected to see
volume growth of approximately 5% to 10% in the third quarter. We anticipate our
results for the third  quarter to be in a range of net income of $0.01 per share
to $0.03 per share,  excluding the impact of previously announced  restructuring
charges related to the exit of photonic technologies or CAV, any gains or losses
related to the Avanex sale or debt buybacks 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 $1.5 billion in cash and short-term  investments,  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 second 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  $21  million  for  the  estimated  liability  for
environmental  cleanup and related  litigation at June 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.

We have also been informed that a complaint by the New York Attorney  General to
recover  approximately  $10 million in  environmental  clean-up costs associated
with a landfill  in Bath,  NY is about to be brought  against us and eight other
potentially responsible parties.

Risk Factors

Set forth below and elsewhere in this Quarterly  Report,  and in other documents
we file with the SEC, are some of the  principal  risks and  uncertainties  that
could  cause  our  actual  business  results  to  differ   materially  from  any
forward-looking  statements  or other  projections  contained in this  Quarterly
Report.  In addition,  future  results could be  materially  affected by general
industry and market conditions, general U.S. and non-U.S. economic and political
conditions, including a global economic slowdown, fluctuation in tariffs, import
duties, interest rates or currency exchange rates, terrorism,  political unrest,
or  international  conflicts,  political  instability or major health  concerns,
natural  disasters or other  disruptions of expected  economic  conditions.  Our
separate  statement  labeled  Forward-Looking  Statements on the preceding  page
should be considered in addition to the statements below.

Risks Relating to Our Business

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

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

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

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

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

     In our Technologies segment,  several of our businesses have a concentrated
customer  base.  These  businesses   include  Corning's  display   technologies,
environmental  products and  semiconductor  materials.  If we lose a significant
customer in any of these businesses, our sales could be negatively impacted.

     Although the sale of display glass has increased from quarter to quarter in
2003,  there can be no  assurance  that this  upward  trend  will  continue.  As
customers  switch to larger size glass,  the pace of orders may be uneven  while
they adjust their manufacturing processes and facilities. Although we anticipate
growth  in  demand  in this  industry,  our  capital  investments  in plant  and
equipment  may not produce the  anticipated  returns if future  customer  demand
fails to meet our expectations.








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

     In the economic and industry downturn for our  Telecommunications  segment,
we have responded to the softer market by cutting costs, including the reduction
of our manufacturing  volumes.  We executed our restructuring  plans in 2002 and
into 2003. Much of our photonic technologies business assets will be transferred
on or about July 31,  2003,  to Avanex  Corporation  and other  portions of that
business  being  retained by us will be  restructured,  sold or shut down during
2003. We previously  closed two fiber  facilities and  "mothballed"  another and
closed several factories that made photonics, cabling or hardware and equipment.

     We have  announced a $180 million  expansion of our Tainan,  Taiwan  liquid
crystal  display  glass  facility  in  response to  increased  customer  demand.
Although  we expect to  complete  planned  improvement  and  expansion  projects
associated   with  this   business,   we  may  not  achieve  the   manufacturing
efficiencies, product improvements or level of sales that we anticipate.

     As a  consequence  of the current  economic  downturn,  we have reduced our
workforce by  approximately  21,000  positions as of June 30, 2003.  Although we
expect  to  complete  our  planned  restructuring  and  facility   consolidation
activities, we may not achieve all of the cost reductions that we anticipate. We
cannot assure you that our plans will be  successful  in mitigating  the adverse
effects of a softer market,  nor can we assure you that  additional  adjustments
and charges will not be necessary to respond to further market changes.

     In  addition,  our  restructuring  program  and current  business  plan are
designed to get us back to  profitability  and positive cash flow, but we cannot
be certain  that this will  occur or that we will  return to  profitability  and
positive cash flow within the time period we are targeting.

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

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

     The  telecommunications  industry was severely hampered in 2002 and 2003 by
excess  manufacturing  capacity,  increased intensity of competition and growing
pressure in price and profits. These negative trends are expected to continue in
2003. In 2002 and 2003,  we recorded  charges for  restructuring,  impairment of
assets and the  write-off of cost and equity based  investments.  It is possible
that additional  impairments,  restructuring  charges and inventory  write-downs
will result from the telecommunications industry downturn.

     Our  ability to  forecast  our  customers'  needs for our  products  in the
current  economic and industry  environment is limited.  Our results in 2002 and
into 2003 included  significant  charges for  impairment  of long-lived  assets,
primarily  in  the  conventional  television  glass  and  photonic  technologies
businesses.

     Corning  may record  additional  charges for  restructuring  or other asset
impairments in 2003 if additional  actions become  necessary to align costs to a
reduced level of demand.

     In the  event we incur  continued  operating  losses,  we may be  unable to
recognize  future  deferred tax assets and may be required to make an assessment
of our ability to realize the deferred tax assets already recorded.  At June 30,
2003, we had recorded net deferred tax assets of approximately $1.5 billion.






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

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

     .    our ability to introduce leading products such as glass for flat panel
          displays,  optical fiber and environmental substrate products that can
          command competitive prices in the marketplace;
     .    our ability to maintain  or achieve a favorable  mix of sales  between
          premium and non-premium products;
     .    our ability to  continue  to develop new product  lines to address our
          customers'  diverse needs within the several market  segments in which
          we participate.  This requires a high level of innovation,  as well as
          the accurate anticipation of technological and market trends;
     .    our  ability  to pace  expansions  of  manufacturing  facilities  with
          sustainable customer demand; or
     .    our ability to anticipate  the pace and timing of clean air regulation
          that may affect the  emission  control  products in our  environmental
          business.

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

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

     We periodically face pricing pressures in each of our leading businesses as
a  result  of  intense   competition,   emerging  new   technologies,   customer
developments,  or overcapacity.  While we will work toward reducing our costs to
respond  to the  pricing  pressures  that  may  continue,  we may not be able to
achieve  proportionate  reductions in costs. As a result of overcapacity and the
current  economic  and  industry  downturn  in the  Telecommunications  segment,
pricing  pressures  continued into 2003,  particularly  in our optical fiber and
cable business.  Pricing pressures are expected to continue for the remainder of
2003.

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

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

     Effective  January 1, 2002, we adopted the Financial  Accounting  Standards
Board Statement of Financial Accounting Standards (SFAS) No. 142. Under SFAS No.
142, goodwill is no longer amortized but is subject to impairment tests at least
annually. Management completed the impairment test in the fourth quarter of 2002
and recorded required goodwill  impairment charges totaling $400 million for the
Telecommunications  segment.  While we believe the estimates and judgments about
future cash flows in the Telecommunications segment are reasonable, no assurance
can be given that the  businesses in this segment will  stabilize and recover as
projected.  We cannot provide assurance that future impairment  charges will not
be required if the telecommunications  industry does not recover as projected by
management in its expected cash flow estimates.







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

     Although we believe  existing cash,  short-term  investments  and borrowing
capacity,  collectively,  provide adequate  resources to fund ongoing  operating
requirements,  we may be  required  to  seek  additional  financing  to  compete
effectively in our markets.  Our public debt ratings affect our ability to raise
capital and the cost of such capital.  In July 2002, Fitch downgraded our senior
unsecured  long-term debt rating from BBB- to BB;  Standard & Poor's  downgraded
our senior unsecured  long-term debt rating from BBB- to BB+ and short-term debt
credit rating from A-3 to B; and Moody's reduced our senior unsecured  long-term
debt rating from Baa3 to Ba2 and  short-term  debt credit rating from Prime-3 to
Not Prime.  Two of the rating agencies have maintained  negative  outlooks while
Fitch  recently  upgraded  our outlook  from  negative to stable.  These and any
further  downgrades  may increase our borrowing  costs and affect our ability to
access the debt capital  markets.  In addition,  the pricing of our common stock
may limit our ability to access the equity capital markets without a significant
dilution to current shareholders.

     As a result of our lower  debt  ratings,  we may face  difficulties  in our
business.  For  example,  we may  face  increasing  requirements  to  post  cash
collateral  for  performance  bonds,  and some  customers  may seek  alternative
suppliers.

     Our  revolving  credit  facility  includes a covenant  that  requires us to
maintain a ratio of total debt to capital, as defined under the credit facility,
of not greater  than 0.60 to 1.00.  Our total debt to capital  ratio was 0.40 at
June 30, 2003.  This  covenant  may also limit our ability to borrow  additional
funds.   Further  declines  in  our   Telecommunications   segment  could  cause
impairments of goodwill,  tangible or intangible assets or restructuring charges
related  to our  overall  business.  Additional  impairments  or  charges  could
materially  increase  our total  debt to  capital  ratio,  which may  reduce the
amounts we are able to borrow under our revolving credit facility.

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

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

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

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






We face intense competition in most of our businesses

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

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

     We may encounter  difficulties  in  protecting  our  intellectual  property
rights or obtaining  rights to  additional  intellectual  property  necessary to
permit us to continue or expand our  businesses.  We cannot  assure you that the
patents that we hold or may obtain will provide  meaningful  protection  against
our  competitors  or  competitive  technologies.  Litigation may be necessary to
enforce our intellectual  property  rights,  to protect our trade secrets and to
determine  the  validity  and scope of our  proprietary  rights.  Litigation  is
inherently  uncertain and the outcome is often  unpredictable.  Other  companies
hold patents on technologies used in our industries and are aggressively seeking
to expand, enforce and license their patent portfolios.

     The  intellectual  property  rights of others could  inhibit our ability to
introduce new products.  We are, and may in the future be,  subject to claims of
intellectual property infringement or misappropriation, and we cannot assure you
as to the outcome of such claims. Litigation or claims against us could force us
to cease selling or using any of our products that  incorporate the intellectual
property that is the subject of such claims, obtain a license from a third party
or redesign or rename our products.  These actions, if possible, could result in
substantial costs or loss of revenue.

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

     Pending,   threatened   or  future   litigation   is  subject  to  inherent
uncertainties. Our financial condition or results of operations may be adversely
affected by unfavorable outcomes, expenses and costs exceeding amounts estimated
or  insured.  In  particular,  we have been  named as a  defendant  in  numerous
lawsuits  against  Pittsburgh  Corning  Corporation  ("PCC") and  several  other
defendants  involving claims alleging personal injury from exposure to asbestos.
As  described  in this report in "Legal  Proceedings,"  Corning has  announced a
settlement  arrangement with  representatives  of the asbestos  claimants.  This
settlement is expected to be incorporated in a Plan of  Reorganization  for PCC.
The  settlement  and the Plan  will be  subject  to a number  of  contingencies,
including a favorable  vote by 75% of the asbestos  claimants  voting on the PCC
Plan, and approval of the bankruptcy  court.  Several of our insurance  carriers
have not agreed to the  settlement  or have  commenced  litigation  to challenge
elements of the  settlement.  Management  cannot provide  assurances  that these
contingencies  will be resolved favorably and there remain  uncertainties  about
the future course of this  litigation.  Corning  recorded an after-tax charge of
$216 million in the first and second quarters of 2003 which management  believes
will be adequate to effect the settlement.  The amount of the charge may require
adjustment each quarter. See Legal Proceedings.





We face risks related to our international operations and sales

     We have customers located outside the United States, as well as significant
non-United States operations,  including  manufacturing and sales. We have large
manufacturing   operations  in  the   Asia-Pacific   region,   including  equity
investments in companies operating in China, Taiwan and South Korea, and several
significant customers are located in this region. As a result of these and other
international operations, we face a number of risks, including:

     .    major health concerns such as SARS;
     .    difficulty of effectively managing our diverse global operations;
     .    change in regulatory requirements;
     .    tariffs, duties and other trade barriers;
     .    undeveloped legal systems;
     .    political and economic instability in foreign markets; and
     .    fluctuations  in foreign  currencies  which may make our products less
          competitive  in countries in which local  currencies  decline in value
          relative to the dollar.

Our results of operations  and financial  performance  may suffer as a result of
key personnel changes

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

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

     In 2002 and into  2003,  certain  of our  customers  experienced  financial
difficulties  and  several  filed  with  the  courts  seeking  protection  under
bankruptcy or reorganization  laws. We have  experienced,  and in the future may
experience,  losses  as a  result  of our  inability  to  collect  our  accounts
receivable,  as well as the loss of such  customer's  ongoing  business.  If our
customers  fail to meet their  payment  obligations  to us, we could  experience
reduced  cash  flows and losses in excess of  amounts  reserved.  As of June 30,
2003, reserves for trade receivables totaled approximately $46 million.

We may not have adequate insurance coverage for claims against us

     We face the risk of loss resulting from, and adverse  publicity  associated
with, product liability, securities, fiduciary liability, intellectual property,
antitrust,  contractual,  warranty, fraud and other lawsuits and investigations,
whether or not such  claims are  valid.  In  addition,  our  product  liability,
fiduciary,  directors and officers, property and comprehensive general liability
insurance  may not be adequate to cover such claims or may not be  available  to
the extent we expect.  Our insurance costs have increased  substantially and may
increase further.  We may not be able to get adequate  insurance coverage in the
future at acceptable costs. A successful claim that exceeds or is not covered by
our policy limits could require us to pay substantial sums. Some of the carriers
in our  historic  excess  insurance  program  are not  rated,  or may have lower
ratings,  and may not be able to respond if we should have claims  reaching into
excess layers.  In addition,  we may not be able to insure against certain risks
or obtain some types of insurance, such as terrorism insurance.






Corning's  results  reflect a  concentration  of  earnings  from  equity  method
investments.   Each  of  these  companies  is  subject  to  separate  risks  and
uncertainties  that could materially  affect its future  operating  results and,
thus, Corning's share of related earnings.

     We have a number of equity method investments.  Corning's share of earnings
relating to three of these  investments,  Samsung  Corning  Co.,  Ltd.,  Samsung
Corning Precision Glass Co., Ltd. and Dow Corning Corporation, is significant to
our consolidated  earnings.  Our participation in these equity companies exposes
us to risks of shared control and future capital  commitments  that, among other
things,  may  adversely  affect the  companies'  business or operating  results.
Further,  each of these companies is subject to separate risks and uncertainties
that could materially  affect its future  operating  results.  For example,  Dow
Corning  Corporation is a global  manufacturer  of specialty  chemicals known as
silicones  that are used in a wide  variety of  applications  for  consumer  and
industrial  uses.  Risks  relating to this business  that may  adversely  affect
operating  results  and  cash  flows  include,  but  are  not  limited  to,  the
cyclicality and volatility of the specialty chemical  industry,  rising costs of
energy and other raw materials, currency risk associated with global operations,
pricing pressure,  safety, and environmental  regulations.  Samsung Corning Co.,
Ltd.,  based in Korea, is a maker of conventional  television tubes and funnels,
which is a mature business. Samsung Corning Precision Glass Co. Ltd., also based
in Korea, manufacturers display glass primarily for sale to panel makers located
in Korea.  Corning's  share of earnings from these companies may vary materially
from quarter to quarter as a result of industry  conditions  and other risks and
uncertainties.








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
six 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.

Interest Rate Risk

At December 31, 2002, our consolidated debt portfolio contained approximately 8%
of variable  rate  instruments.  As a result of the large amount of debt that we
have  repurchased  and retired in 2003,  variable rate  instruments now comprise
approximately 11% of our consolidated  debt portfolio.  Our policy is that total
floating and variable debt will not exceed 35% of the debt portfolio at anytime.


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 June 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 June 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  $21 million for its  estimated
liability for environmental  cleanup and litigation at June 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.  Corning has been  informed  that a complaint  by the New York  Attorney
General to recover  approximately  $10 million in  environmental  clean-up costs
associated  with a landfill  in Bath,  New York is about to be  brought  against
Corning and eight other potentially responsible parties.

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 filed appeals to the U.S. Court of
Appeals for the Sixth  Circuit from the District  Court's  order.  These appeals
have been briefed but not yet  scheduled for  argument.  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
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 did not recognize  equity earnings from the second quarter of
1995  through the end of 2002.  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 June 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,  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. 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 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  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  10,500  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 $133 million  (net  present  value as of June 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 second  quarter of 2003,  Corning  recorded an additional $39
million ($24 million after-tax) to mark-to-market the value of the common stock.

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. 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 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.  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
approximately $12 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.




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 to CIC for approximately $18 million.  Arbitration hearings were
completed in late May 2003, and post-hearing  written  submissions were filed in
June 2003.  The parties will each submit legal  briefs and  additional  evidence
over the next two months and a final  decision is expected by December 31, 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.  Tellium and Astarte have filed motions  seeking to be dismissed
from the  arbitration  based on a variety of  grounds,  and  Corning has opposed
these motions.  The  arbitration  hearings on the claims and  counterclaims  are
scheduled  in  January  2004.  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 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.

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  selling  prices of
standard  single-mode  optical fiber at lower prices than in the respective home
country as well as material  injury alleged to the Chinese fiber  industry.  The
investigation is underway, with a preliminary determination anticipated in 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
in the United States District Court for the Western District of New York against
these three 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.  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.
