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

1. Basis of Presentation

General

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

Corning is a diversified technology company that concentrates its efforts on
high-impact growth opportunities. Corning combines its expertise in specialty
glass, ceramic materials, polymers and the manipulation of the properties of
light, with strong process and manufacturing capabilities to develop, engineer
and commercialize significant innovative products for the telecommunications,
flat panel display, environmental, life sciences and semiconductor industries.

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.

The preparation of financial statements in conformity with GAAP requires
management to make estimates and assumptions that affect amounts reported
therein. Significant estimates and assumptions in these consolidated financial
statements include restructuring and other charges and credits, allowances for
doubtful accounts receivable, estimates of future cash flows and other
assumptions associated with goodwill and long-lived asset impairment tests,
estimates of the fair value of assets held for disposal, environmental and legal
liabilities, income taxes and deferred tax valuation allowances, and the
determination of discount and other rate assumptions for pension and
postretirement employee benefit expenses. Due to the inherent uncertainty
involved in making estimates, actual results reported in future periods may be
different from these estimates.

The results for interim periods are not necessarily indicative of results that
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, 2003.

Certain amounts for 2003 were reclassified to conform to 2004 classifications.

Stock-Based Compensation

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

For purposes of SFAS No. 123 fair value disclosures, each option grant's fair
value is estimated on the grant date using the Black-Scholes option pricing
model. The following are weighted-average assumptions used for grants under our
stock plans:

- -------------------------------------------------------------------------------
Three months Six months
ended June 30, ended June 30,
-------------------- --------------------
2004 2003 2004 2003

Expected life in years 4 5 4 5
Risk free interest rate 3.7% 2.8% 3.3% 2.9%
Expected volatility 50% 79.6% 50% 78.4%
- -------------------------------------------------------------------------------

During the first quarter of 2004, Corning updated its analysis of the historical
stock option exercise behavior of its employees, among other relevant factors,
and determined that the best estimate of the stock options' expected term
granted in the first quarter was 4 years, compared to our previous expected term
estimate of 5 years. Additionally, Corning used a 10-year mean reversion
analysis, as allowed by SFAS No. 123, to determine the volatility assumption
also used to estimate the fair value of options granted in the first quarter.
Prior to 2004, Corning used historical trailing volatility for a period equal to
the expected term of our stock options. Corning believes a mean reversion
analysis provides a better estimate of future volatility expectations.

New Accounting Standard

In May 2004, the FASB issued Staff Position (FSP) No. FAS 106-2, "Accounting and
Disclosure Requirements Related to the Medicare Prescription Drug, Improvement
and Modernization Act of 2003" (FSP No. 106-2), which provides guidance on how
companies should account for the impact of the Medicare Prescription Drug,
Improvement and Modernization Act of 2003 (the "Act") on its postretirement
health care plans. To encourage employers to retain or provide postretirement
drug benefits, beginning in 2006 the federal government will provide non-taxable
subsidy payments to employers that sponsor prescription drug benefits to
retirees that are "actuarially equivalent" to the Medicare benefit. Corning has
determined that its postretirement health care plans' prescription drug benefits
are actuarially equivalent to Medicare Part D benefits to be provided under the
Act. Effective July 1, 2004, Corning will prospectively adopt the accounting
guidance of FSP No. 106-2, which will reduce our postretirement health care and
life insurance plans' accumulated postretirement benefit obligation by $73
million and annual expense by $10 million.

For the six months ended June 30, 2004, we contributed $22 million to our
domestic and international pension plans. We expect to contribute an additional
$23 million in the second half of 2004.

3. Discontinued Operations

On December 13, 2002, we completed the sale of our precision lens business to 3M
Company ("3M") for cash proceeds up to $850 million, of which $50 million was
deposited in an escrow account. 3M has notified Corning that 3M believes it has
certain claims arising out of the representations and warranties made by Corning
in connection with the sale of the precision lens business to 3M. The parties
are attempting to resolve such claims. At June 30, 2004, approximately $49
million remained in the escrow account. No other gain on the sale of the
precision lens business will be recognized until such claims are resolved.
Corning and 3M are negotiating a settlement agreement that will likely result in
Corning receiving less than half of the amount in escrow.

4. Restructuring, Impairment and Other Charges and (Credits)

2004 Restructuring Actions

Second Quarter
- --------------
In the second quarter of 2004, we recorded credits of $34 million ($14 million
after-tax and minority interest) included in restructuring, impairment and other
charges and (credits). A summary of these credits follows:

.. We recorded a $25 million gain ($8 million after-tax and minority interest)
related to proceeds in excess of assumed salvage values for assets of
Corning Asahi Video Products Company (CAV) that were previously impaired
but later sold to a third party in China. CAV was our 51% owned affiliate
that manufactured glass panels and funnels for use in conventional tube
televisions and which was shut down in 2003. In July 2004, we substantially
completed the sale of CAV's assets and received proceeds of $7 million ($2
million after-tax and minority interest).
.. We recorded a $9 million credit ($6 million after-tax) comprised of
reversals of reserves related to prior years' restructuring charges. The
reversals included $2 million related to employee separation costs that
were less than estimated, $5 million related to exit costs that were less
than estimated, and $2 million related to assets that were previously
impaired.

First Quarter
- -------------
In the first quarter of 2004, we recorded net restructuring, impairment and
other charges and (credits) totaling $34 million ($21 million after-tax and
minority interest). A summary of these charges and credits follow:

.. We recorded $39 million of accelerated depreciation and $1 million of exit
costs relating to the final shutdown of our semiconductor materials
manufacturing facility in Charleston, South Carolina, which we announced in
the fourth quarter of 2003.
.. We recorded credits of $6 million, primarily related to proceeds in excess
of assumed salvage values for assets that were previously impaired.

The following table details the charges, credits and balances of the
restructuring liabilities as of and for the six months ended June 30, 2004 (in
millions):

Cash payments for employee related costs will be substantially complete by the
end of 2005, while payments for exit activities will be substantially completed
by the end of 2007. As of June 30, 2004, all of the 1,975 employees from the
2003 restructuring plans have been separated.

2003 Restructuring Actions

Second Quarter
- --------------
In the second quarter of 2003, we recorded net restructuring, impairment and
other charges and (credits) totaling $49 million ($3 million after-tax and
minority interest). A summary of these charges and credits follows:

.. a charge of $54 million ($15 million after-tax and minority interest)
related to the shut down of CAV,
.. a charge of $33 million ($22 million after-tax) related to the exit of the
photonics business,
.. a charge of $38 million ($25 million after-tax) related to restructuring
and impairment actions in the Telecommunications segment and administrative
staffs, and
.. a credit of $76 million ($59 million after-tax) related to prior years'
restructuring and impairment charges, primarily in the Telecommunications
segment.

First Quarter
- -------------
In the first quarter of 2003 we recorded net restructuring, impairment and other
charges and (credits) totaling $51 million ($12 million after-tax and minority
interest). A summary of these charges and credits follows:

.. a $17 million ($11 million after-tax) charge associated with the
discontinuance of optical switching, which was a photonic product, 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,
.. a $5 million ($3 million after-tax) charge for other than temporary
declines in certain cost investments in the Telecommunications segment,
.. a $33 million ($21 million after-tax) reversal of prior years' charges
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, and
.. a $62 million ($19 million after-tax and minority interest) asset
impairment charge related to CAV.

5. Asbestos Settlement

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

The agreement is expected to be incorporated into a settlement fund as part of a
reorganization plan for PCC. The plan was submitted to the federal bankruptcy
court at the end of 2003, received a favorable vote from creditor classes in the
first quarter of 2004, but remains subject to a number of contingencies. The
Bankruptcy Court has set a schedule for briefing leading to final arguments in
November 2004. We will make our contributions to the settlement trust under the
agreement after the plan is approved, becomes effective and is no longer subject
to appeal.

When the plan becomes effective, our settlement will require the contribution of
our equity interest in PCC, our one-half equity interest in Pittsburgh Corning
Europe N.V. (PCE), and 25 million shares of our common stock. The common stock
will be marked-to-market each quarter until the settlement plan is approved,
thus resulting in adjustments to income and the settlement liability as
appropriate. The agreement also includes the contribution of cash payments with
a current value of $140 million over six years beginning one year after the plan
becomes effective. We may accelerate a substantial portion of the payments to as
early as 2005, as needed, to maximize the related tax benefits. In addition, we
will assign insurance policy proceeds from our primary insurance and a portion
of our excess insurance as part of the settlement.

The following summarizes the charges we have recorded to reflect the initial
settlement and to mark-to-market the value of our common stock:

Pretax charge $ 47 $ 39 $ 66 $ 337
After-tax charge $ 45 $ 24 $ 63 $ 216
- --------------------------------------------------------------------------------

The minimal tax effect on the charges for the three and six months ended June
30, 2004 reflects the fact that the cumulative asbestos settlement charge
recorded to date is in excess of the net amount realizable for tax purposes.
Beginning with the first quarter of 2003 and through June 30, 2004, we have
recorded charges of $479 million ($327 million after-tax) to reflect the initial
settlement and to mark-to-market the value of our common stock.

The carrying value of our stock in PCE and the fair value of 25 million shares
of our common stock as of June 30, 2004 ($348 million) have been reflected in
other accrued liabilities. The remaining $140 million, representing the net
present value of the cash payments discounted at 5.5%, is recorded in other
liabilities. See Part II-Other Information, Item 1. Legal Proceedings for a
history of this matter.

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

The effective (income tax) benefit rate for the three and six months ended June
30, 2004 and 2003 differed from the U.S. statutory income tax rate of 35% due to
the impact of restructuring, impairment and other charges and (credits),
asbestos settlement and debt transactions.

8. Investments

At June 30, 2004 and December 31, 2003, our total investments accounted for by
the equity method were $1.1 billion and $978 million, respectively. Summarized
results of operations of our two significant equity method investments follow
(in millions):

Samsung Corning Precision Glass Co., Ltd. (Samsung Corning Precision)

Gross profit $ 205 $ 94 $ 384 $ 170
Net income $ 145 $ 64 $ 271 $ 114
- ------------------------------------------------------------------------------------------------------------------------------------

Our investment in Samsung Corning Precision, a 50%-owned South Korea based
manufacturer of liquid crystal display glass, was $395 million and $299 million
at June 30, 2004 and December 31, 2003, respectively.

Corning and Samsung Corning Precision routinely enter into purchase and sale
transactions for glass. Sales to Samsung Corning Precision were insignificant
for the quarter ended June 30, 2004 and $7 million for the quarter ended June
30, 2003. Sales to Samsung Corning Precision were $6 million and $12 million for
the six months ended June 30, 2004 and 2003, respectively. Purchases from
Samsung Corning Precision totaled $15 million and $5 million for the quarters
ended June 30, 2004 and 2003, and $37 million and $8 million for the six months
ended June 30, 2004 and 2003, respectively. Balances due to and from Samsung
Corning Precision were immaterial at June 30, 2004 and December 31, 2003.
Profits related to inventories on hand at the end of a period are eliminated
during consolidation.

Our investment in Dow Corning, a 50%-owned U.S. based manufacturer of silicone
products, was $207 million and $185 million at June 30, 2004 and December 31,
2003, respectively.

During the second quarter of 2004, Dow Corning recorded charges related to
restructuring actions and adjustments to interest liabilities recorded on its
emergence from bankruptcy. Our equity earnings included $21 million related to
these charges. Subject to future rulings by the bankruptcy court and potential
changes in estimated bankruptcy-related liabilities, it is possible that Dow
Corning may record bankruptcy-related charges in the future. For information
related to Dow Corning litigation and bankruptcy proceedings see Part II-Other
Information, Item 1. Legal Proceedings.

11. Long-Term Debt

During the second quarter of 2004, we issued 10 million shares of common stock
and paid $9 million in cash in exchange for 97,500 of our 3.5% convertible
debentures with a book value of $98 million. In accordance with SFAS No. 84,
"Induced Conversions of Convertible Debt," we recorded a loss of $9 million ($9
million after-tax) reflecting the fair value of the cash paid and incremental
shares issued beyond those required by the terms of the debentures. The increase
in equity due to issuance of shares from treasury stock was $88 million.

During the first quarter of 2004, our long-term debt transactions included the
following:

Issuance of Long-Term Debt

In March 2004, we issued $400 million of senior unsecured notes, of which $200
million aggregate principal amount of 5.90% notes mature on March 15, 2014 and
$200 million aggregate principal amount of 6.20% notes mature on March 15, 2016.
These senior unsecured notes were issued under our existing $5 billion universal
shelf registration statement, which became effective in March 2001. We realized
net proceeds of approximately $396 million from the issuance of these notes. We
will pay interest semi-annually on these senior unsecured notes on March 15 and
September 15.

Loss on Repurchases and Retirement of Debt, Net

3.5% convertible debentures
- ---------------------------
During the first quarter of 2004, we issued 22 million shares of common stock
and paid $24 million in cash in exchange for our 3.5% convertible debentures
with a book value of $213 million resulting in a loss of $23 million ($21
million after-tax).

Zero coupon convertible debentures
- ----------------------------------
During the first quarter of 2004, we repurchased and retired 150,000 zero coupon
convertible debentures with a book value of $119 million in exchange for cash of
$117 million. The gain on the transaction was offset by the write-off of the
unamortized issuance costs.

12. Commitments and Contingencies

In 2003, we adopted the initial recognition and measurement provisions of FASB
Interpretation No. 45 (FIN 45). We do not routinely provide significant
third-party guarantees and, as a result, this interpretation has not had a
material effect on our financial statements.

We provide financial guarantees and incur contingent liabilities in the form of
purchase price adjustments related to attainment of milestones, stand-by letters
of credit and performance bonds. These guarantees have various terms, and none
of these guarantees are individually significant. We have also agreed to provide
a credit facility related to Dow Corning as discussed in Note 10 to the
Consolidated Financial Statements in our 2003 Annual Report on Form 10-K.
Corning's obligation to fund the Dow Corning $150 million credit facility may be
triggered if in the next ten years Dow Corning is unable to meet its obligations
to fund the settlement payments required under its Bankruptcy Plan. Corning
believes that Dow Corning has sufficient cash flow and liquidity to meet its
current obligations. As of June 30, 2004, we were contingently liable for the
items described above totaling $352 million, compared with $445 million at
December 31, 2003. We believe a significant majority of these guarantees and
contingent liabilities will expire without being funded.

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

15. Operating Segments

SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," set standards for reporting information regarding operating
segments in financial statements. Operating segments are defined as components
of an enterprise about which separate financial information is available that is
evaluated regularly by the chief operating decision maker, or decision making
group, in deciding how to allocate resources and in assessing performance. Our
Chief Operating Decision-Making group (CODM) is comprised of the chairman and
chief executive officer, vice chairman and chief financial officer, president
and chief operating officer, president-Corning Technologies, executive vice
president-chief administrative officer and executive vice president-chief
technology officer.

Effective with the first quarter of 2004, we revised our reportable operating
segments from Telecommunications and Technologies to Telecommunications, Display
Technologies, Environmental Technologies and Life Sciences. Prior year
information has been restated to conform to this revision. The following
provides a brief description of the products and markets served by each
reportable segment:

.. Telecommunications - manufactures optical fiber and cable and hardware and
equipment components for the worldwide telecommunications industry;
.. Display Technologies - manufactures liquid crystal display glass substrates
for flat panel displays;
.. Environmental Technologies - manufactures ceramic substrates and filters
for automobile and diesel applications; and
.. Life Sciences - manufactures glass and plastic consumables for scientific
applications.

The change in our segment presentation reflects how Corning's CODM allocates
resources and assesses the performance of its businesses. Specifically, the CODM
is significantly increasing its level of review of the Display Technologies
segment due to the recent increase in growth and capital spending in that
segment. In addition, the CODM is increasing its review of the Environmental
Technologies and Life Sciences segments to strengthen the overall balance and
stability of Corning's portfolio of businesses.

All other operating segments that do not meet the quantitative threshold for
separate reporting (e.g., specialty materials, ophthalmic products and
conventional video components), certain corporate investments (e.g., Dow
Corning, Samsung Corning Company Ltd. and Steuben), discontinued operations and
unallocated expenses have been grouped as "Unallocated and Other". Unallocated
expenses include research and other expenses related to new business
development; gains or losses on repurchases and retirement of debt; charges
related to the asbestos litigation; and restructuring and impairment charges
related to the corporate research and development or staff organizations.
Unallocated and Other also represents the reconciliation between the totals for
the reportable segments and our consolidated total.

We prepare the financial results for our 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 include the
earnings of equity affiliates that are closely associated with our operating
segments in the respective segment's net income. We have allocated certain
common expenses among segments differently than we would for stand-alone
financial information prepared in accordance with GAAP. These expenses include
interest, taxes and corporate functions. Segment net income may not be
consistent with measures used by other companies. The accounting policies of our
operating segments are the same as those applied in the consolidated financial
statements.

structures do not receive additional allocations of interest expense.
(4) Many of Corning's administrative and staff functions are performed on a
centralized basis. Where practicable, Corning charges these expenses to
segments based upon the extent to which each business uses a centralized
function. Other staff functions, such as corporate finance, human resources
and legal are allocated to segments primarily as a percentage of sales.
(5) (Loss) income before minority interests and equity (losses) earnings
includes an allocation of depreciation of corporate property, plant and
equipment not specifically identifiable to a segment. Related depreciable
assets are not allocated to segment assets.
(6) Minority interests include the following restructuring, impairment and
other charges and (credits):
For the three and six months ended June 30, 2004, gains from the sale
of assets of Corning Asahi Video Products Company in excess of assumed
salvage value of $13 and $14, respectively.
For the three and six months ended June 30, 2003, charges related to
impairment of long-lived assets of Corning Asahi Video Products

16. Subsequent Events

On July 1, 2004, Corning received notice from substantially all of the holders
of its $100 million 7.625% debentures that they had exercised their put options
which were to expire July 2, 2004. Settlement on these debentures will occur in
the third quarter of 2004. These debentures are classified as loans payable as
of June 30, 2004 and December 31, 2003.

On July 8, 2004, Corning announced the sale of its frequency control business,
which is part of the Telecommunications segment. The frequency control business
had 2003 annual sales of $76 million. We expect to close the transaction in the
third quarter of 2004 and recognize a pretax loss approximating $25 million.

On July 21, 2004, Corning and Chi Mei Optoelectronics Corp. (Chi Mei) entered
into a long-term purchase and supply agreement of large size LCD glass. The
agreement is a five-year contract by which the Display Technologies segment will
supply Generation 5.5 glass to Chi Mei's new LCD fabrication facility in Tainan,
Taiwan. The contract calls for significant quantities of LCD glass to be
supplied to Chi Mei starting in 2005. As part of the agreement, Chi Mei will
make advance cash deposits of $510 million to Corning in several installments in
2004 and 2005 for a portion of the contracted glass to be purchased.

The key terms of this contract follow:

.. The customer will make cash deposits totaling $510 million to be paid in
installments. The first installment of $102 million deposit was received in
July 2004. Corning will receive a second $102 million deposit in the fourth
quarter of 2004. The customer will make four remaining deposits of $76.5
million on a quarterly basis through the fourth quarter of 2005.

.. Upon receipt of the cash deposits made by the customer, Corning will record
a customer deposit liability, which will be applied in the form of credits
against future glass purchases over the life of the contract.

.. Corning will supply up to maximum agreed upon quantities of glass
substrates to the customer over a five-year period beginning in the first
quarter of 2005 through the fourth quarter of 2009.

.. As glass is shipped to the customer, Corning will recognize revenue at the
selling price and issue a credit memo for an agreed amount of the customer
deposit liability. These credit memos will be applied against receivables
resulting from the sale of glass to Chi Mei and will thus reduce operating
cash flows over the five year period of the contract.

.. In the event the customer does not make all customer deposit installment
payments or elects not to purchase the agreed upon quantities of glass
substrates, subject to specific conditions outlined in the agreement,
Corning may retain certain amounts of the customer deposit. Likewise, if
Corning does not deliver glass substrates to Chi Mei, subject to specific
conditions outlined in the agreement, Corning may be required to return
certain amounts of the customer deposit.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

Overview

We continue to focus on three key priorities in 2004: protect our financial
health, improve our profitability, and invest in the future. We continue to make
progress towards all three in 2004.

Financial Health
During the second quarter of 2004, we continued to make strides in improving our
balance sheet and delivering positive cash flows from operating activities. The
following are the highlights for the quarter:

.. As part of our ongoing debt reduction program, we retired $98 million of
our 3.5% convertible debentures.
.. We reduced our days sales outstanding to 53 days, primarily as a result of
more timely settlement of our accounts receivable balances relating to
customers in the Display Technologies segment.
.. We improved our total debt to capital ratio to 31% at June 30, 2004
compared to 34% at December 31, 2003.
.. We generated sufficient cash flows from operating activities for the three
and six months ended June 30, 2004 to cover the capital expenditures for
those respective periods.
.. We ended the quarter with $1.6 billion in cash, cash equivalents, and
short-term investments at June 30, 2004. This represents an increase of
approximately $300 million compared to our balance at December 31, 2003,
primarily due to the issuance of $400 million senior unsecured notes in the
first quarter of 2004.

Profitability
For the three months ended June 30, 2004, we generated net income of $108
million, or $0.07 per share. This represents an improvement of $130 million, or
$0.09 per share, compared to the prior year quarter. This improvement was
primarily driven by the growth of our Display Technologies segment and the
impact of our restructuring actions, most noticeably in the Telecommunications
segment. For the six months ended June 30, 2004, our net income improved by $390
million, or $0.30 per share, compared to the prior year period. The drivers for
this improvement include the same items identified for the three months ended
comparison, as well as the lower charges incurred in 2004 related to the
asbestos settlement.

Investing in our Future
We continue to invest in a wide array of technologies, with our focus being
glass substrates for active matrix liquid crystal displays (LCDs), diesel
filters and substrates in response to tightening emissions control standards,
and optical fiber and cable and hardware and equipment that will enable
fiber-to-the-premises. Our research, development and engineering expenses were
9% of sales for the three and six months ended June 30, 2004. This was down from
the respective periods ended June 30, 2003, but we believe our current spending
levels are adequate to enable us to execute our growth strategies.

Our capital expenditures are primarily focused on expanding manufacturing
capacity for liquid crystal display (LCD) glass substrates in the Display
Technologies segment and diesel products in the Environmental Technologies
segment. Total capital expenditures for the three and six months ended June 30,
2004 were $168 million and $302 million, respectively. Of these amounts, $127
million and $225 million, respectively, were directed toward the Display
Technologies segment. In order to keep pace with the LCD market expansion, and
due to faster than anticipated cash payments related to certain construction
projects in Taiwan, we have increased our 2004 forecasted consolidated capital
spending to $950 million to $1 billion. Of this amount, $750 million to $800
million will be directed toward expanding our manufacturing capacity in the
Display Technologies segment.

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

Net Sales
Net sales increased 29%, or $219 million, for the three months ended June 30,
2004, compared to the prior year quarter. The primary drivers of this growth
were the continued high demand for glass substrates in our Display Technologies
segment and demand for products in our Telecommunications segment due to general
increases in network spending, particularly in North America and Europe. For the
six months ended June 30, 2004, our net sales increased $317 million, or 21%,
compared to the prior year period. The growth in the Display Technologies
segment was the primary driver. Strong performance in the Environmental
Technologies segment, for both automotive and diesel products, as well as our
other operating segments more than offset the sales decreases resulting from our
exiting of the conventional video and photonic technologies businesses.
Movements in foreign exchange rates, primarily the Japanese Yen and Euro, did
not have a significant impact on sales for the three and six months ended June
30, 2004, compared to their respective 2003 periods.

Gross Margin
As a percentage of net sales, gross margin improved 12 percentage points for the
three months ended June 30, 2004, compared to the prior year quarter. For the
six months ended June 30, 2004, the improvement was 11 percentage points
compared to the prior year period. The improvement in both periods can be
attributed to: (a) lower depreciation and fixed costs due to the restructuring
actions taken in 2003, most notably the exit of the conventional television
businesses, and (b) revenue growth in the Display Technologies segment of 105%
and 101% for the respective three and six month periods.

Selling, General and Administrative Expenses
As a percentage of sales, selling, general and administrative expenses decreased
3 points and 2 points for the three and six months ended June 30, 2004,
respectively, compared to the corresponding periods in 2003. For the three and
six months ended June 30, 2004, selling, general and administrative expenses
increased $18 million and $26 million, respectively, compared to the
corresponding periods in 2003. These increases were related to general increases
in compensation costs and additional headcount. The additional headcount is
primarily to support the growth in the Display Technologies segment.

Research, Development and Engineering
As a percentage of sales, research, development and engineering expenses
decreased by 2 points and 3 points for the three and six months ended June 30,
2004, respectively, compared to the corresponding periods in 2003. The decline
of $9 million in the six month period is reflective of the exit from the
photonic technologies business in 2003 offset by increased spending in Display
Technologies and Life Sciences to fund new product development.

Restructuring, Impairment and Other Charges and (Credits)
Restructuring, impairment and other charges and (credits) was a credit of $34
million for the three months ended June 30, 2004 compared to a net charge of $49
million for the prior year quarter. For the six months ended June 30, 2004,
charges and credits from restructuring and impairment actions have offset each
other, compared to a net charge of $100 million for the prior year period. Refer
to Note 4 to the Consolidated Financial Statements for additional information.

Asbestos Settlement
For the three and six months ended June 30, 2004, we recorded charges of $47
million and $66 million, respectively, related to the quarterly mark-to-market
of our common stock associated with the asbestos settlement agreement. For the
three and six months ended June 30, 2003, we recorded charges of $39 million and
$337 million, respectively, as part of our asbestos settlement, the latter of
which included $298 million associated with the initial settlement. Refer to
Note 5 to the Consolidated Financial Statements for additional information.

Income (Loss) Before Income Taxes
For the three months ended June 30, 2004, we recognized $36 million of income
before income taxes compared to a loss of $149 million for the prior year
quarter. For the six months ended June 30, 2004, we incurred a loss before
income taxes of $28 million compared to a loss of $594 million for the prior
year period. For both the three and six month comparisons, the key drivers are
outlined under Gross Margin, Restructuring, Impairment and Other Charges and
(Credits), and Asbestos Settlement.

In addition to the above, the following had a material effect on the results of
our income (loss) before income taxes:

Refer to Note 11 to the Consolidated Financial Statements and Corning's 2003
Annual Report on Form 10-K for additional information regarding the gains
(losses) recognized on the repurchase and retirement of debt for the respective
periods.

Income Taxes
Our (provision) benefit for income taxes and the related effective (income tax)
benefit rates were as follows (in millions):

- --------------------------------------------------------------------------------------------------------------------------
Three months Six months
ended June 30, ended June 30,
---------------------- -----------------------

Effective (income tax) benefit rate (66.7)% 22.8% (42.9)% 30.0%
- --------------------------------------------------------------------------------------------------------------------------

The effective (income tax) benefit rate for the three and six months ended June
30, 2003 and 2004 differed from the U.S. statutory income tax rate of 35%, due
to the impact of restructuring, impairment and other charges and (credits),
asbestos settlement and debt transactions.

At June 30, 2004, we have recorded gross deferred tax assets of approximately
$2.0 billion with a valuation allowance of approximately $450 million. The
valuation allowance is primarily attributable to the uncertainty regarding the
realization of specific foreign and state 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, state and 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. We have performed the required
assessment of positive and negative evidence regarding the realization of the
net deferred tax assets in accordance with Statement of Financial Accounting
Standards (SFAS) No. 109, "Accounting for Income Taxes," (SFAS No. 109). This
assessment included the evaluation of scheduled reversals of deferred tax
liabilities, estimates of projected future taxable income and tax planning
strategies as well as related key assumptions, which are further described in
Note 9 to the Consolidated Financial Statements in Corning's 2003 Annual Report
on Form 10-K. We believe the key assumptions underlying our assessment continue
to be appropriate. Although realization is not assured, based on our assessment,
we have concluded that it is more likely than not that such assets, net of the
existing valuation allowance, will be realized. Refer to the Risk Factors and
Critical Accounting Estimates in our Annual Report on Form 10-K for additional
information.

Equity Earnings
For the three months ended June 30, 2004, equity earnings increased $47 million,
or 78%, compared to the prior year quarter, primarily due to the strong
performance of Samsung Corning Precision Glass Company, Ltd. (Samsung Corning
Precision). For the six months ended June 30, 2004, equity earnings increased
$95 million, or 80%, compared to the prior year period, primarily due to Samsung
Corning Precision. A summary of equity earnings follows (in millions):

During the second quarter of 2004, Dow Corning Corporation (Dow Corning)
recorded a restructuring charge and a charge to adjust interest liabilities due
to court rulings on its emergence from bankruptcy. Our equity earnings in the
second quarter of 2004 included $21 million related to these charges.

Refer to Note 8 to the Consolidated Financial Statements for additional
information relating to Samsung Corning Precision and Dow Corning's operating
results.

OPERATING SEGMENTS

Effective with the first quarter of 2004, we revised our reportable operating
segments from Telecommunications and Technologies to Telecommunications, Display
Technologies, Environmental Technologies and Life Sciences. Prior year
information has been restated to conform to this revision. The following
provides a brief description of the products and markets served by each
reportable segment:

.. Telecommunications - manufactures optical fiber and cable and hardware and
equipment components for the worldwide telecommunications industry;
.. Display Technologies - manufactures liquid crystal display glass substrates
for flat panel displays;
.. Environmental Technologies - manufactures ceramic substrates and filters
for automobile and diesel applications; and
.. Life Sciences - manufactures glass and plastic consumables for scientific
applications.

The change in our segment presentation reflects how Corning's Chief Operating
Decision Making group (CODM) allocates resources and assesses the performance of
its businesses. Specifically, the CODM is significantly increasing its level of
review of the Display Technologies segment due to the recent increase in growth
and capital spending in that segment. In addition, the CODM is increasing its
review of the Environmental Technologies and Life Sciences segments to
strengthen the overall balance and stability of Corning's portfolio of
businesses.

We prepare the financial results for our 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 include the
earnings of equity affiliates that are closely associated with our operating
segments in the respective segment's net income. 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 United States. These expenses include interest, taxes
and corporate functions. Segment net income may not be consistent with measures
used by other companies. The accounting policies of our operating segments are
the same as those applied in the consolidated financial statements.

For the three months ended June 30, 2004, sales increased by $45 million, or
13%, compared to the prior year quarter. This performance was led by sales in
North America and Europe, primarily driven by general increases in network
spending including demand from the fiber-to-the-premises build-out. For the
comparable periods, fiber volumes were up 24% while pricing pressures continued
resulting in declines of 9%. Movements in foreign exchange rates, primarily the
Japanese Yen and Euro, did not have a significant impact on sales for the three
months ended June 30, 2004, compared to the prior year quarter.

For the six months ended June 30, 2004, sales increased $5 million compared to
the prior year period. The strong results in the second quarter of 2004 were
substantially offset by the impact of the 2003 exit of the photonic technologies
business and a decline of fiber sales in Japan and China in the first quarter of
2004, compared to the prior year quarter. For the comparable six month periods,
fiber volumes declined 2% and prices declined 10%. Movements in exchange rates
for the comparable six month periods did not significantly impact sales.

The Telecommunications segment experienced losses for each of the periods
presented. Performance improved for the respective comparable periods primarily
due to the impact of the prior years' restructuring and impairment actions and
the exit of the photonic technologies business.

During the second quarter of 2004, the Chinese Ministry of Commerce issued an
anti-dumping preliminary determination asserting that Corning had dumped optical
fiber in China during 2002 and 2003. The company is continuing to cooperate with
the Chinese Ministry of Commerce to reach a final determination. Refer to
Critical Accounting Policies and Estimates of this Form 10-Q for additional
information regarding the preliminary determination.

Outlook:
- --------
We expect sales in the third quarter of 2004 to be down from the second quarter
of 2004, with fiber volumes declining between 10% and 15% and moderate pricing
declines. We expect to see continued strength in North America and Europe,
primarily due to seasonal buying patterns, but these will be offset by the
impact of the recent China anti-dumping preliminary ruling.

For the three months ended June 30, 2004, sales increased $142 million, or 105%,
compared to the prior year quarter. This performance was reflective of the
overall LCD-market growth. For the second quarter of 2004, glass substrate
volumes (measured in square feet of glass sold) increased approximately 80% as
LCD panel makers brought on additional capacity during the quarter. Sales were
also benefited by modest average price increases, primarily the result of a
change in product mix as the market continues to trend toward large size glass
substrates (generation 5 and above) which carry a higher selling price per
square foot. The sales of the Display Technologies segment are largely Asian
based and, as such, are susceptible to movements in the US dollar - Japanese Yen
exchange rates. For the second quarter of 2004, sales benefited by approximately
7% from a weakening of the US dollar compared to the same period in 2003.

For the six months ended June 30, 2004, sales increased $255 million, or 101%,
compared to the prior year period. The factors affecting the six-month
performance are largely the same as those identified for the second quarter of
2004. For the comparable six month period, glass substrate volumes increased
approximately 75%, average pricing increases were modest, and movements in the
US dollar - Japanese Yen exchange rates benefited sales by approximately 9%
compared to the same period in 2003.

For the three and six months ended June 30, 2004, income before equity earnings
increased by more than 2.5 times compared to the prior quarter and more than
tripled compared to the prior year period. For both periods, the key drivers
were the impact of incremental volumes and efficiencies realized through the
shift in production toward large size glass substrates. Movements in the U.S.
dollar - Japanese Yen exchange rates did not have a significant impact on income
before equity earnings for the three and six months ended June 30, 2004,
compared to their respective 2003 periods. The increases in our equity earnings
from Samsung Corning Precision for the periods presented were largely driven by
the same factors identified for our wholly-owned business.

The Display Technologies segment manufactures and sells glass substrates to a
concentrated customer base comprised of LCD panel makers primarily located in
Japan and Taiwan. LCD panels are used in computer products, such as notebook
computers and desktop monitors, consumer electronics products, such as digital
cameras and camcorders and car navigation systems, and LCD televisions. For the
three and six months ended June 30, 2004, six LCD customers accounted for 80%
and 76%, respectively, of the Display Technologies segment sales.

Corning and these customers have typically entered into multi-year supply
agreements for the purchase and sale of glass substrates. These agreements
provide for Corning to supply a percentage of the customers' requirements and
include mechanisms for forecasting and ordering. During the second quarter of
2004, Corning improved the payment terms under these agreements to improve cash
flow and reduce its working capital requirements.

The LCD market continues to grow rapidly. This growth is being driven, in part,
by higher demand for LCD televisions, for which our LCD customers require larger
size glass substrates. Over the past few months, Corning has held discussions
with several of its customers to discuss how to meet this demand. As part of its
discussions, Corning has sought improved payment terms, including deposits
against orders, to provide a greater degree of assurance that we are effectively
building capacity to meet the needs of a rapidly growing industry. There can be
no assurance that Corning will be able to pace its capacity expansion to the
actual demand and, while the industry has grown rapidly, it is possible that
glass manufacturing capacity may exceed demand during certain periods.

On July 21, 2004, Corning and Chi Mei Optoelectronics Corp. (Chi Mei) entered
into a long-term purchase and supply agreement of large size LCD glass. The
agreement is a five-year contract under which Corning will supply Generation 5.5
glass to Chi Mei's new LCD fabrication facility in Tainan, Taiwan. The contract
calls for significant quantities of LCD glass to be supplied to Chi Mei starting
in 2005. As part of the agreement, Chi Mei will make advance cash deposits of
$510 million to Corning in several installments in 2004 and 2005 for a portion
of the contracted glass to be purchased. Refer to Note 16 to the Consolidated
Financial Statements for a summary of this contract's key terms.

In the ordinary course of business, Corning will continue to negotiate
multi-year supply agreements with its large customers where feasible.

Outlook:
- --------
We expect to see a continuation of the overall industry growth and the trend
toward large size substrates into the third quarter. We continue to see positive
trends in the penetration rates of LCD's into the end-markets (notebook
computers, monitors and televisions), and increasing needs for the large size
substrates. Volume growth from the second to third quarter of 2004 is
anticipated to be approximately 10% and average pricing is projected to remain
stable. In addition, we expect to remain sold out throughout the quarter and
plan to bring on additional capacity throughout the year. There can be no
assurance that the end-market rates of growth will continue at the high rates
experienced in recent quarters. Consumer preferences for panels of differing
sizes, or price or other factors, may lead to pauses in market growth from time
to time.

For the three months ended June 30, 2004, sales increased $24 million, or 21%,
compared to the prior year quarter. We continue to see strong demand for our
automotive and diesel products in response to ever-tightening emission standards
around the world. Our automotive products benefited from both an increase in
volume and a higher mix of our thin-wall and ultra thin-wall substrates, which
allow our customers to meet their emission control requirements in a more cost
effective manner. Our diesel products continue to gain greater market
penetration, and volumes were almost double the prior year quarter. Although
showing strong growth, diesel products represented a modest portion of the total
Environmental Technologies sales for the three months ended June 30, 2004. A
portion of the sales of the Environmental Technologies segment are susceptible
to movements in the US dollar - Euro exchange rates. For the quarter, sales
received a minor benefit from a weakening of the US dollar.

For the six months ended June 30, 2004, sales increased $50 million, or 22%,
compared to the prior year period. The factors affecting the six-month period
performance are largely the same as those identified for the quarter.

For the three and six months ended June 30, 2004, the segment experienced modest
net income increases compared to the respective prior year periods. The full
benefits of the increases in product volumes and higher mix of thin-wall and
ultra thin wall automotive substrates are largely being offset by development
and engineering costs for our diesel products.

Outlook:
- --------
For the third quarter of 2004, we expect to see sales comparable to those of the
second quarter. Diesel regulatory trends remain on track for the United States,
Europe and Japan, and we anticipate another strong quarter for this product
line.

Life Sciences

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

For the three months ended June 30, 2004, sales increased $7 million, or 10%,
compared to the prior year quarter. Volume increases across the majority of our
product lines, coupled with a favorable US dollar - Euro exchange rate, drove
the sales increase compared to the second quarter of 2003.

For the six months ended June 30, 2004, sales increased $13 million, or 9%,
compared to the prior year period. The factors affecting the six-month period
performance are largely the same as those identified for the quarter.

For the three and six months ended June 30, 2004 net income was consistent with
that of the comparable period. For the three and six month periods the
incremental gross margin improvements resulting from the increase in sales
volumes have been largely offset by new product development costs. In addition,
for the six month period, the comparison of net income was negatively impacted
due to a gain recognized in the first quarter of 2003 on the disposition of a
minor product line.

Outlook:
- --------
For the third quarter of 2004, we expect sales comparable to those of the second
quarter. We expect a continuation of the positive trends in pharmaceutical
spending, of capital infusion into the biotechnology market, and government
spending.

Unallocated and Other includes all other operating segments that do not meet the
quantitative threshold for separate reporting (e.g., specialty materials,
ophthalmic products, and conventional video components), certain corporate
investments (e.g., Dow Corning, Samsung Corning Company. Ltd. and Steuben),
discontinued operations and unallocated expenses. Unallocated expenses include
research and other expenses related to new business development; gains or losses
on repurchases and retirement of debt; charges related to the asbestos
litigation; and restructuring and impairment charges related to the corporate
research and development or staff organizations. Unallocated and Other also
represents the reconciliation between the totals for the reportable segments and
our consolidated total.

Sales were down slightly for the three and six months ended June 30, 2004
compared to their respective prior year periods. The 2004 decrease of
conventional video components sales is due to our second quarter 2003 decision,
along with our partner, to cease production and shut down our 51% owned
affiliate, Corning Asahi Video Products Company (CAV), which was a manufacturer
of glass panels and funnels for use in conventional tube televisions. The
improved sales performance in our other segments is largely due to higher sales
generated by our specialty materials business.

Refer to the discussion regarding Restructuring, Impairment, and Other Charges
and (Credits) and Asbestos Settlement for a description of the key drivers of
net loss for periods presented.

LIQUIDITY AND CAPITAL RESOURCES

Financing Structure
During the second quarter of 2004, we issued 10 million shares of common stock
and paid $9 million in cash in exchange for 97,500 of our 3.5% convertible
debentures with a book value of $98 million. We recorded a loss of $9 million
($9 million after-tax) relating to the retirement of debt.

During the first quarter of 2004, we issued 22 million shares of common stock
and paid $24 million in cash in exchange for our 3.5% convertible debentures
with a book value of $213 million. In addition, we repurchased 150,000 of our
zero coupon convertible debentures with a book value $119 million for $117
million in cash. As a result of these transactions, we recorded a loss of $23
million ($21 million after-tax).

In March 2004, we issued $400 million of senior unsecured notes under our
existing $5 billion universal shelf registration statement, which became
effective in March 2001. We realized net proceeds of $396 million from the
issuance of these notes. As of June 30, 2004, our remaining capacity under the
shelf registration was approximately $2.5 billion.

As an additional source of funds, we currently have full unrestricted access to
a $2 billion revolving credit facility with 17 banks, expiring on August 17,
2005. As of June 30, 2004, 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, 2004, this ratio
was 31%.

Capital Spending
Capital spending totaled $302 million and $110 million during the six months
ended June 30, 2004 and 2003, respectively. In order to keep pace with the LCD
market expansion, and due to faster than anticipated cash payments related to
certain construction projects in Taiwan, we have increased our 2004 forecasted
consolidated capital spending to $950 million to $1 billion.

On July 21, 2004, Corning announced its board of directors had approved a
capital expenditure plan of $750 million to further expand manufacturing
capacity for LCD glass substrates. The majority of these expenditures will be
used for the development of our new facility in Taiwan. Corning's board also
approved preliminary funding for additional LCD manufacturing capacity expansion
projects in Taiwan and Japan. Approximately $200 million of capital expenditures
will occur in 2004, and have been included in the above updated forecast, with
the remaining approximately $550 million of capital expenditures occurring in
2005 and 2006.

Restructuring
During the six months ended June 30, 2004, we made payments of $41 million
related to employee severance and termination costs and $15 million in other
exit costs resulting from restructuring actions. We expect additional payments
to range from $30 million to $45 million in 2004 for actions taken in 2001, 2002
and 2003.

Key Balance Sheet Data
At June 30, 2004, cash, cash equivalents and short-term investments totaled $1.6
billion, compared with $1.3 billion at December 31, 2003. The increase was
primarily due to cash proceeds received from the issuance of the $400 million of
senior unsecured notes and cash provided by operating activities, offset by
repurchases of long-term debt and capital spending during the six months ended
June 30, 2004.

Balance sheet and working capital measures are provided in the following table

Management Assessment of Liquidity
Our major source of funding for 2004 and beyond will be our existing balance of
cash, cash equivalents and short-term investments. From time to time we may also
issue debt or equity securities to raise additional cash to fund a portion of
our capital expenditures related to our growth businesses. We believe we have
sufficient liquidity for the next several years to fund operations,
restructuring, the asbestos settlement, research and development, capital
expenditures and scheduled debt repayments.

Contractual Obligations
There have been no material changes outside the ordinary course of business in
the contractual obligations disclosed in our 2003 Annual Report on Form 10-K
under the caption "Contractual Obligations."

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 2003 Annual Report on Form 10-K and remain unchanged through
the second quarter of 2004.

As discussed under Part II- Other Information, Item 1. Legal Proceedings, on
June 16, 2004, the Chinese Ministry of Commerce (the Ministry) issued its
preliminary determination relating to its anti-dumping investigation against
manufacturers of optical fiber based in the U.S., Korea and Japan. The
preliminary determination asserts that Corning had dumped optical fiber in China
during the relevant period in 2002 and 2003, and that the responding parties had
materially injured Chinese producers. The Ministry stipulated that Corning's
preliminary dumping duty was 16%. Chinese purchasers of the affected Corning
optical fiber will have to pay the amount of this duty in the form of a cash
deposit. Corning is vigorously contesting this preliminary determination through
additional filings and may be able to appeal within the Ministry or the Chinese
legal system if the final determination is adverse. Corning's fiber export
revenues to China were approximately 6% of optical fiber and cable revenues.
Corning management estimates that the impact of any potential loss of fiber
export volume to China should be less than $0.01 in earnings per share in the
second half of 2004. Given the preliminary nature of the ruling by the Ministry,
we do not believe this matter results in an interim event of impairment by
itself, which would require us to test the Telecommunications segment goodwill
for recoverability in accordance with SFAS No. 142. However, should the
preliminary determination become final, it will negatively impact our long-term
outlook for the Telecommunications segment, and may require us to test goodwill
for recoverability.

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, 2004. Based upon the
information developed to date, we believe that the accrued amount is a
reasonable estimate of our liability and that the risk of an additional loss in
an amount materially higher than that accrued is remote.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk Disclosures

There have been no material changes to our market risk exposure during the first
six months of 2004. For a discussion of our exposure to market risk, refer to
Item 7A, Quantitative and Qualitative Disclosures About Market Risks, contained
in our 2003 Annual Report on Form 10-K.

ITEM 4. CONTROLS AND PROCEDURES

The Company carried out an evaluation, under the supervision and with the
participation of the Company's management, including the Company's chief
executive officer and its chief financial officer, of the effectiveness of the
design and operation of the Company's disclosure controls and procedures as of
June 30, 2004, the end of the period covered by this report. Based upon the
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 the Company
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.

During the fiscal quarter ended June 30, 2004, there has been no change in our
internal control over financial reporting 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, 2004. Based upon
the information developed to date, management believes that the accrued reserve
is a reasonable estimate of the Company's estimated liability and that the risk
of an additional loss in an amount materially higher than that accrued is
remote.

Schwinger and Stevens Toxins Lawsuits. In April 2002, Corning was named as a
defendant in two actions, Schwinger and Stevens, filed in the U.S. 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 likelihood of a materially adverse impact to Corning's financial
statements is remote.

Dow Corning Bankruptcy. Corning and Dow Chemical each own 50% of the common
stock of Dow Corning, which has been in reorganization proceedings under Chapter
11 of the U.S. Bankruptcy Code since May 1995. Dow Corning filed for bankruptcy
protection to address pending and claimed liabilities arising from many thousand
breast-implant product lawsuits each of which typically sought damages in excess
of one million dollars. 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. After review and
approvals by the Bankruptcy Court and the U.S. District Court of the Eastern
District of Michigan, and an appeal, the District Court on April 2, 2004 entered
an order establishing June 1, 2004 as the effective date of the Joint Plan.

Under the terms of the Joint Plan, Dow Corning will establish a Settlement Trust
and a Litigation Facility to provide a means for tort claimants to settle or
litigate their claims. Dow Corning has 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. As required by the Joint
Plan, Dow Corning has fully satisfied (or reserved for) the claims of its
commercial creditors in accordance with a March 31, 2004 ruling of the District
Court determining the amount of pendency interest allowed on the $810 million in
principal owing on such claims. In the second quarter of 2004, Dow Corning
recorded a $47 million adjustment to its interest liabilities relating to this
matter, of which Corning recognized $14 million reflected in its second quarter
equity earnings. Certain commercial creditors have appealed from that ruling to
the U.S. Court of Appeals of the Sixth Circuit seeking from Dow Corning an
additional sum of approximately $100 million for interest at default rates and
enforcement costs. Corning believes the risk of loss to Dow Corning (net of sums
reserved) is remote.

In 1995, Corning fully impaired its investment in Dow Corning upon its entry
into bankruptcy proceedings and did not recognize equity earnings from the
second quarter of 1995 through the end of 2002. Corning began recognizing equity
earnings in the first quarter of 2003 when management concluded that its
emergence from bankruptcy protection was probable. Corning considers the
difference between the carrying value of its investment in Dow Corning and its
50% share of Dow Corning's equity to be permanent. This difference is $249
million. Subject to future rulings by the bankruptcy court and potential changes
in estimated bankruptcy-related liabilities, it is possible that Dow Corning may
record bankruptcy-related charges in the future.

Corning received no dividends from Dow Corning in 2003 or in the first half of
2004.

Implant Tort Lawsuits. Corning and Dow Chemical, the shareholders of Dow
Corning, were named in several thousand 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. The
federal breast implants cases against Corning were dismissed by summary judgment
entered in the U.S. District Court of the Northern District of Alabama in 1995.
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. Certain Louisiana cases were
transferred to the U.S. District Court for the Eastern District of Michigan to
which substantially all breast implant cases were transferred in 1997. In light
of the confirmation of the Plan of Reorganization, providing a channeling of all
claims into facilities established by the Plan and releasing the shareholders,
management believes that the likelihood of a materially adverse impact to
Corning's financial statements is remote.

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 U.S. 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 June 2003, Corning filed a motion
for summary judgment. 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 impact to Corning's financial statements is remote.

From December 2001 through April 2002, Corning and three of its officers and
directors were named defendants in lawsuits alleging violations of the U.S.
securities laws in connection with Corning's November 2000 offering of 30
million shares of common stock and $2.7 billion zero coupon convertible
debentures, due November 2015. In addition, the Company and the same three
officers and directors were named in lawsuits alleging misleading disclosures
and non-disclosures that allegedly inflated the price of Corning's common stock
in the period from September 2000 through July 9, 2001. The plaintiffs in these
actions seek to represent classes of purchasers of Corning's stock in all or
part of the period indicated. On August 2, 2002, the U.S. District Court of the
Western District of New York entered an order consolidating these actions for
all purposes, designating lead plaintiffs and lead counsel, and directing
service of a consolidated complaint. The consolidated amended complaint requests
substantial damages in an unspecified amount to be proved at trial. In February
2003, defendants filed a motion to dismiss the complaint for failure to allege
the requisite elements of the claims with particularity. The Court heard
arguments on May 29 and June 9, 2003 and on April 9, 2004 entered a Decision and
Order dismissing the complaint. In May 2004, Plaintiffs filed a notice of appeal
to the U.S. Court of Appeals of the Second Circuit. Management is prepared to
defend these lawsuits vigorously. Recognizing that the outcome of litigation is
uncertain, management believes that the likelihood of a materially adverse
impact to Corning's financial statements, net of applicable insurance, is
remote.

Pittsburgh Corning Corporation. Corning and PPG Industries, Inc. ("PPG") each
own 50% of the capital stock of 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 U.S. 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 and typically requesting
monetary damages in excess of one million dollars per claim. 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 11,300
other cases (approximately 42,300 claims) alleging injuries from asbestos and
similar amounts of monetary damages per claim. 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 on several occasions 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 approval by the bankruptcy
court. Corning's settlement will require the contribution, when the Plan becomes
effective, of its 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 $140 million (net present value as of June 30, 2004) in six
installments beginning one year after the Plan is effective. In addition,
Corning will assign policy rights or proceeds under primary insurance from 1962
through 1984, as well as rights to 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 recorded an initial charge of $298 million ($192 million after-tax) in
the period ending March 31, 2003 to reflect the settlement terms. However, the
amount of the charge for this settlement requires 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 2004, Corning recorded an
additional charge of $47 million ($45 million after-tax) to reflect the
mark-to-market of Corning common stock. Beginning with the first quarter of 2003
and through June 30, 2004, Corning recorded total charges of $479 million ($327
million after-tax) to reflect the settlement and to mark-to-market the value of
Corning common stock.

Two of Corning's primary insurers and several excess insurers have commenced
litigation 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 received a favorable vote from creditors in March 2004. Hearings to
consider objections to the Plan were held in the Bankruptcy Court in May 2004.
That Court has set a schedule for briefing leading to final arguments in
November 2004. Additional appeals by objecting parties are reasonably possible.
Although the confirmation of the PCC Plan is subject to a number of
contingencies, apart from the quarterly adjustment in the value of 25 million
shares of Corning common stock, management believes that the likelihood of a
material adverse impact to Corning's financial statements is remote.

Astrium. In December of 2000, Astrium, SAS and Astrium, Ltd. filed a complaint
for negligence in the U.S. 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 that Astrium may have experienced. In April 2002, the
Court granted motions for summary judgment by NetOptix and other defendants to
dismiss the negligence claims, but permitted plaintiffs to add fraud and
negligent misrepresentation claims against all defendants and a breach of
warranty claim against NetOptix and its subsidiaries. In October 2002, the Court
again granted defendants' motions for summary judgment and dismissed the
negligent misrepresentation and breach of warranty claims. The intentional fraud
claims were dismissed against all non-settling defendants on February 25, 2003.
On March 19, 2003, Astrium appealed all of the Court's Rulings regarding the
various summary judgment motions to the Ninth Circuit Court of Appeals. The
Circuit Court has stayed the appeal pending a decision in a case being appealed
to the California Supreme Court involving similar issues of law. Recognizing
that the outcome of litigation is uncertain, management believes that the
likelihood of a materially adverse impact to Corning's financial statements is
remote.

Furukawa Electric Company. On February 3, 2003, The Furukawa Electric Company
filed suit in the Tokyo District Court in Japan against Corning Cable Systems
International Corporation ("CCS International") alleging infringement of
Furukawa's Japanese Patent No. 2,023,966 which relates to separable fiber ribbon
units used in optical cable. Furukawa's complaint requests slightly over (Y)6
billion in damages (approximately $56 million) and an injunction against further
sales in Japan of these fiber ribbon units. CCS International has denied the
allegation of infringement, asserted that the patent is invalid, and is
defending vigorously against this lawsuit. Several hearings have been held
before the Tokyo District Court and the next hearing is scheduled for July 30,
2004. Management believes that the likelihood of a materially adverse impact to
Corning's financial statements is remote.

Chinese Anti-Dumping Investigation. On July 1, 2003, the Chinese Ministry of
Commerce announced an anti-dumping investigation against manufacturers of
optical fiber based in the U.S, Korea and Japan, alleging that standard
single-mode optical fiber was sold in China at lower prices than in the
respective home country. This matter does not present a claim for damages. On
June 16, 2004 the Ministry's preliminary determination was issued which found
that Corning had dumped optical fiber in China during the relevant period in
2002 and 2003, and that the responding parties had materially injured Chinese
producers. The Ministry stipulated that Corning's preliminary dumping duty was
16%. Chinese purchasers of the affected Corning optical fiber will have to pay
the amount of this duty in the form of a cash deposit. Corning is vigorously
contesting this preliminary determination through additional filings and may be
able to appeal within the Ministry or the Chinese legal system if the final
determination is adverse. Corning's fiber export revenues to China were
approximately 6% of optical fiber and cable revenues. Corning management
estimates that the impact of any potential loss of fiber export volume to China
should be less than $0.01 in earnings in the second half of 2004.

PicVue Electronics Ltd., PicVue OptoElectronics International, Inc. and
Eglasstrek Gmbh. In June 2002, Corning brought an action seeking to restrain the
use of its trade secrets and for copyright infringement relating to certain
aspects of the fusion draw machine used for liquid crystal display glass
melting. This action is pending in the U.S. District Court for the Western
District of New York against these three named defendants. The District Court in
July 2003 denied the PicVue motion to dismiss and granted a preliminary
injunction in favor of Corning, subject to posting a bond in an amount to be
determined. PicVue, a Taiwanese company, responded in July 2003 with a
counterclaim alleging violations of the antitrust laws and claiming damages of
more than $120 million as well as requesting trebled damages. PicVue has
appealed the District Court's ruling and the District Court has deferred ruling
on the bond amount until the completion of such appeal. The appellate court
affirmed the grant of the preliminary injunction, but remanded the case for the
District Court to clarify the scope of the injunction and to consider what, if
any, bond should be posted. The parties have submitted papers to the District
Court addressing the issues remanded. The District Court has not ruled on the
remanded issues or determined the amount of the bond. 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
impact to Corning's financial statements is remote.

Tyco Electronics Corporation and Tyco Technology Resources, Inc. On August 13,
2003, CCS Holdings Inc. ("CCS"), a Corning subsidiary, filed an action in the
U.S. District Court for the Middle District of North Carolina against Tyco
Electronics Corporation and Tyco Technology Resources, Inc. ("Tyco"), asking the
court to declare a Tyco patent invalid and not infringed by CCS. The patent
generally relates to a type of connector for optical fiber cables. Tyco has
responded with a motion to dismiss the action for lack of jurisdiction. That
motion has been fully briefed by the parties, and Tyco has requested a hearing.
Management has not estimated the range of monetary damages that may be claimed
if CCS does not prevail on its claim that the Tyco patent is invalid or not
infringed. Recognizing that the outcome of litigation is uncertain, management
believes that the risk of a material impact on Corning's financial statements is
remote.

Grand Jury Investigation of Conventional Cathode Ray Television Glass Business.
In August 2003, CAV was served with a federal grand jury document subpoena
related to pricing, bidding and customer practices involving conventional
cathode ray television glass picture tube components. Eight employees or former
employees have each received a related subpoena. CAV is a general partnership,
51% owned by Corning and 49% owned by Asahi Glass America, Inc. CAV's only
manufacturing facility in State College, Pennsylvania closed in the first half
of 2003 due to declining sales. CAV is cooperating with the government
investigation. Management is not able to estimate the likelihood that any
charges will be filed as a result of the investigation.

the recommendation. In response, the Compensation Committee and Board of
Directors considered and adopted a policy on July 21, 2004 implementing this
proposal. The new Board policy is to seek shareholder approval for any future
severance agreements entered after July 21, 2004 with senior executive officers
that provide benefits exceeding 2.99 times the sum of such senior executive
officer's base salary plus bonus.
