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

(1)  Information by Operating Segment
     Information about the performance of Corning's three operating segments for
     the  second  quarter  and first six  months of 2001 and 2000 are  presented
     below.  These amounts  exclude  revenues,  expenses and equity earnings not
     specifically   identifiable  to  segments.   Segment  net  income  excludes
     impairment   and   amortization   of   goodwill   and  other   intangibles,
     restructuring charges, purchased in-process research and development costs,
     one-time  acquisition costs and other  nonrecurring  items. This measure is
     not in accordance with generally accepted accounting  principles (GAAP) and
     may not be consistent with measures used by other companies.

     Corning prepared the financial results for its three operating  segments on
     a basis  that is  consistent  with the manner in which  Corning  management
     internally disaggregates financial information to assist in making internal
     operating  decisions.  Corning has  allocated  some common  expenses  among
     segments  differently  than it would for stand alone financial  information
     prepared in accordance with GAAP.  During the quarter ended March 31, 2001,
     Corning realigned one product line from the Advanced Materials segment into
     the Telecommunications segment. Segment results for 2000 have been restated
     to conform to the current presentation.

(2)  Business Combinations
     The transaction listed below was accounted for under the purchase method of
     accounting.  Management is responsible for estimating the fair value of the
     assets  and  liabilities  acquired.   Management  has  made  estimates  and
     assumptions  that affect the reported  amounts of assets,  liabilities  and
     expenses resulting from such acquisitions.

     Tropel
     ------
     On March 16, 2001, Corning completed the acquisition of Tropel Corporation,
     a  manufacturer  of  precision  optics and  metrology  instruments  for the
     semiconductor and other  industries,  for approximately $66 million in cash
     and 1.95 million  shares of Corning common stock for a total purchase price
     of  approximately  $160 million.  The excess of the purchase price over the
     estimated  fair value of tangible  net assets  acquired  was  allocated  to
     goodwill.  Goodwill of  approximately  $155 million is being amortized on a
     straight-line basis over 15 years.

(3)  Impairment of Goodwill and Intangible Assets
     During the first half of 2001, Corning  experienced a significant  decrease
     in the rate of growth of its telecommunications  segment,  primarily in the
     photonic technologies business, due to a dramatic decline in infrastructure
     spending in the  telecommunications  industry.  During the second  quarter,
     major customers in the photonic technologies business further reduced their
     order forecasts and canceled orders already placed. Management now believes
     that the growth  prospects  of this  business are  significantly  less than
     previously expected and those of historical periods.






     Corning  reviews the  recoverability  of its long-lived  assets,  including
     goodwill  and  other   intangible   assets,   when  events  or  changes  in
     circumstances  occur that indicate the carrying  value of the asset may not
     be recoverable. As a result of the business conditions noted above, Corning
     concluded such an assessment was required for its photonics business in the
     second quarter. Corning assesses recoverability of the carrying value based
     upon  cumulative  expected  future  pre-tax  cash flows  (undiscounted  and
     without interest charges) of the related operations.

     As a result of this test,  Corning  determined that the long-lived  assets,
     including goodwill and other intangibles  acquired from Pirelli in December
     2000 as well as those of the unit into which NetOptix Corporation (acquired
     in May, 2000) has been integrated were not recoverable. Corning's policy is
     to write-down long-lived assets to fair value in such circumstances.

     Management estimated fair value using several techniques. While each method
     generated  comparable  fair  values,  management  adjusted  the  assets  to
     estimates based on average multiples of forecasted revenues and earnings of
     comparable  publicly  traded  companies  with  operations  in  the  optical
     component market segment.

     In the second quarter,  Corning  recorded pre-tax charges of $4,648 million
     to impair a  significant  portion of  goodwill  and $116  million to impair
     intangible  assets.  Of the total charge of $4,764 million,  $3,154 million
     related to the acquisition of the Pirelli optical  components  business and
     $1,610  million  related to  goodwill  resulting  from the  acquisition  of
     NetOptix Corporation.

(4)  Provision for Inventory
     During the second  quarter,  major  customers in the photonic  technologies
     business  further reduced their order forecasts and canceled orders already
     placed. As a result,  management  determined that certain products were not
     likely to be sold in their product life cycle. Corning recorded a provision
     for  excess  and   obsolete   inventory,   including   estimated   purchase
     commitments,  of $273 million  ($184 million after tax) in cost of sales in
     the second quarter of 2001.

     million and 10  million,  respectively,  of  potential  common  shares from
     options,  and 30 million  convertible  shares from the subordinated  notes,
     convertible preferred stock and the zero coupon convertible debentures.  In
     addition,  49 million  potential  common  shares from options were excluded
     since the option  exercise  price was greater than the average market price
     of the common shares for the period.

     Diluted earnings per share for the six months ended June 30, 2000 exclude 7
     million shares from subordinated notes and convertible preferred stock, due
     to the anti-dilutive effect they would have had if converted.

     Common  dividends  of $56 million  and $112  million  were  declared in the
     second  quarter and first six months of 2001  compared with $52 million and
     $102  million  for the same  periods  in 2000.  Dividends  per  share  were
     comparable  between  years.  On  July 9,  2001,  Corning  announced  it was
     discontinuing the declaration and payment of future dividends on its common
     stock.

(6)  Depreciation and Amortization
     Depreciation charged to operations for the second quarter and six months of
     2001  totaled  $163 million and $318  million,  respectively.  Depreciation
     charged to operations for the second quarter and six months of 2000 totaled
     $126 million and $238 million, respectively.

     Amortization  of  purchased   intangibles  including  goodwill  charged  to
     operations  for the  second  quarter  and six months of 2001  totaled  $160
     million  and  $316  million,   respectively.   Amortization   of  purchased
     intangibles including goodwill charged to operations for the second quarter
     and six months of 2000 totaled $49 million and $62 million, respectively.

(7)  (Benefit) Provision for Income Taxes
     Corning's tax (benefit)  provision for the second quarter and six months of
     2001 was impacted by the significant  impairment charge and amortization of
     goodwill. Corning's effective tax rate for the second quarter and first six
     months of 2000 was 53.8% and 49.0%,  respectively.  Excluding the impact of
     the impairment of goodwill and other  intangibles  (which is mostly non-tax
     deductible),  amortization of purchased intangibles and goodwill, purchased
     in-process research and development,  one-time  acquisition costs and other
     nonrecurring  items,  the effective  income tax rate for the second quarter
     and six months of 2001 was 32.5%,  which is comparable to rates of 32.4% in
     both periods in 2000.

(8)  Inventories
     Inventories shown on the accompanying  balance sheets were comprised of the
     following:

(10) Pittsburgh Corning Corporation
     Corning  and PPG  Industries,  Inc.  each own 50% of the  capital  stock of
     Pittsburgh Corning Corporation (PCC). 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
     240,000 open claims.  At the time of its Chapter 11 filing,  PCC sought and
     obtained a temporary restraining order and filed a motion for a preliminary
     injunction  against the  prosecution  of asbestos  actions  against its two
     shareholders  to afford  the  parties  a period  of time  (the  "Injunction
     Period") in which to negotiate a plan of  reorganization  for PCC. On April
     4, 2001, the Bankruptcy Court extended the exclusive period for PCC to file
     a plan of reorganization (the "Exclusivity Period") until July 9, 2001, and
     extended  the  Injunction  Period to August 23,  2001.  At a July 25,  2001
     hearing,  the Bankruptcy Court entered an order upon consent of the parties
     extending the Injunction  Period to November 30, 2001 and  terminating  the
     Exclusivity Period. Under the terms of the Bankruptcy Court's April 4, 2001
     Order,  PCC,  PPG  Industries  and  Corning  will  have 90  days  following
     expiration of the Injunction  Period to seek removal and transfer of stayed
     cases that have not been resolved  through a plan of  reorganization.  As a
     result of PCC's bankruptcy filing,  Corning recorded an after tax charge of
     $36 million in the first quarter of 2000 to impair its entire investment in
     PCC and discontinued  recognition of equity earnings. At the time PCC filed
     for bankruptcy  protection,  there were approximately 12,400 claims pending
     against Corning alleging various theories of liability based on exposure to
     PCC's asbestos products.  These cases are stayed pursuant to the injunction
     of the  bankruptcy  court.  Before  PCC  filed for  bankruptcy  protection,
     Corning was dismissed from similar claims as cases against PCC proceeded to
     trial. The Chapter 11 filing may lead to additional  claims against Corning
     with related costs of defense,  charges and expenses.  Although the outcome
     of litigation and the  bankruptcy  case is uncertain,  management  believes
     that the  separate  corporate  status of PCC will  continue  to be  upheld.
     Management  is continuing to  investigate  Corning's  options for defending
     claims against it, which might include  vigorously  defending itself on all
     fronts or exploring a global settlement through the bankruptcy  process. It
     is probable that there will be intensive negotiations  throughout the third
     quarter of 2001 concerning terms of PCC's plan of reorganization, including
     whether  or not  Corning  and its  insurers  may  participate  by  making a
     contribution  in exchange  for a release.  Management  cannot  estimate the
     probability  that  Corning will be able to secure such a release upon terms
     and conditions  satisfactory to Corning and its insurers. The range of cost
     for these  options  (net of  insurance)  cannot be  estimated at this time.
     Although asbestos  litigation is inherently  difficult,  and the outcome of
     litigation is uncertain, management believes these matters will be resolved
     without a materially adverse impact on Corning's financial position.






(11) Dow Corning Corporation
     Corning and The Dow  Chemical  Company (Dow  Chemical)  each own 50% of the
     common stock of Dow Corning  Corporation  (Dow Corning),  a manufacturer of
     silicones.

     On May 15, 1995, Dow Corning  sought  protection  under the  reorganization
     provisions  of Chapter 11 of the United  States  Bankruptcy  Code.  At that
     time, Corning management  believed it was impossible to predict if and when
     Dow Corning would  successfully  emerge from Chapter 11  proceedings.  As a
     result,  Corning  recorded  an after tax  charge of $366  million  to fully
     reserve  its  investment  in Dow Corning and  discontinued  recognition  of
     equity  earnings  from Dow Corning in 1995.  The  bankruptcy  proceeding is
     pending in the United States  Bankruptcy  Court for the Eastern District of
     Michigan,  Northern  Division (Bay City,  Michigan).  The bankruptcy filing
     stayed  the  prosecution  against  Dow  Corning  of  approximately   19,000
     breast-implant  product liability lawsuits,  including 45 class actions. In
     1998,  Dow Corning  and the Tort  Claimants  Committee  engaged in extended
     negotiations  and reached  certain  compromises.  On November 8, 1998,  Dow
     Corning and the Tort  Claimants  Committee  jointly filed a revised Plan of
     Reorganization  (Joint Plan).  Following a favorable vote from all but four
     classes of  creditors,  a hearing to confirm the Joint Plan was held in mid
     1999.

     On November 30, 1999, the Bankruptcy  Court entered an order confirming the
     Joint Plan and indicated that certain  written  opinions  would follow.  On
     December 21, 1999, the Bankruptcy Court issued an opinion that approved the
     principal  elements of the Joint Plan with respect to tort  claimants,  but
     construed the Joint Plan as providing releases for third parties (including
     Corning  and Dow  Chemical  as  shareholders)  only  with  respect  to tort
     claimants  who  voted in favor  of the  Joint  Plan.  A number  of  parties
     opposing the Joint Plan filed appeals on a variety of grounds to the United
     States District Court for the Eastern District of Michigan. Dow Corning and
     the Tort Claimants Committee filed a notice of appeal seeking review of the
     ruling  limiting  the scope of the  shareholder  releases.  On November 13,
     2000, the District Court entered an Order affirming the Bankruptcy  Court's
     November 30, 1999 Order confirming the Joint Amended Plan and reversing the
     Bankruptcy  Court's December 21, 1999 Opinion on the release and injunction
     provisions.  On February 5, 2001,  the  District  Court denied a Motion for
     Reconsideration.  Approximately  20 appeals from the District Court's Order
     are pending in the Sixth  Circuit  Court of  Appeals,  which is expected to
     rule in late 2001. Further appellate activity,  which may include petitions
     for review by the U.S.  Supreme  Court,  could delay a final judgment until
     late 2002 or possibly into 2003.  After all appeals are  exhausted,  if the
     Joint Plan is upheld but the  shareholder  releases are effective  only for
     those voting in favor of the Joint Plan, Corning would expect to defend any
     remaining  claims  against it on the same  grounds  that led to a series of
     orders and judgments  dismissing all claims against  Corning in the federal
     courts and the state  courts as  described  under the heading  Implant Tort
     Lawsuits  in Part  II,  Item 1,  Legal  Proceedings.  With  respect  to the
     possibility of additional  direct or indirect claims against Corning if the
     full  releases are not  reinstated in the Joint Plan,  management  believes
     that such claims 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.  Dow Corning
     proposes to provide the required  funding over the 16 year period through a
     combination  of  cash,   proceeds  from  insurance,   and  cash  flow  from
     operations.  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 the issuance of senior notes, to its commercial creditors.  If and
     when Dow Corning  emerges from  bankruptcy,  Corning  expects to resume the
     recognition of equity earnings from Dow Corning. Corning does not expect to
     receive dividends from Dow Corning in the foreseeable future.







(12) Adoption of New Accounting  Standard - Derivative  Financial  Instruments -
     FAS 133
     Effective January 1, 2001, Corning adopted Financial  Accounting  Standards
     Board Statement No. 133, "Accounting for Derivative Instruments and Hedging
     Activities,"  (FAS 133) as amended by FAS No. 137 and FAS No. 138.  FAS 133
     requires that all  derivative  financial  instruments  be recognized in the
     financial  statements and measured at fair value  regardless of the purpose
     or  intent  for  holding  them.  Changes  in the fair  value of  derivative
     financial instruments are either recognized periodically in net earnings or
     shareholders'  equity,  as  a  component  of  other  comprehensive  income,
     depending on whether the  derivative is being used to hedge changes in fair
     value or cash  flows.  Changes in fair  value of  ineffective  portions  of
     hedges are  recognized in earnings in the current  period.  The adoption of
     FAS 133 as of January 1, 2001, resulted in a cumulative after-tax credit to
     comprehensive income of $3 million. For the six months ended June 30, 2001,
     after-tax  income under $1 million was recorded in other  expense,  net for
     the ineffective portion of cash flow hedges.

(13) Subsequent Events

     Restructuring
     -------------
     On  July  9,  2001,   Corning   announced  a  downsizing  of  its  photonic
     technologies business. Corning's board of directors approved plans to close
     three  manufacturing  plants,  downsize  the  workforce  and exit  selected
     products.

     Management  is  continuing  to  evaluate  the  need for  further  personnel
     reductions and other restructuring actions elsewhere in the company.  Costs
     related  to  these   potential   additional   actions   and  the   photonic
     manufacturing facility closures already announced are expected to result in
     a third quarter pre-tax charge of $300 million to $400 million.  The charge
     is  expected  to be  predominantly  noncash  (up to 75%) and  will  include
     impairments  of fixed assets,  severance  costs  associated  with workforce
     reductions and other exit costs including lease termination amounts.

     Business Combinations
     ---------------------
     On July 24, 2001, Corning announced it had reached an agreement with Lucent
     Technologies to purchase Lucent's  controlling  equity interest in Shanghai
     Fiber Optic Co., Ltd.  (58%) and Beijing Fiber Optic Cable Co., Ltd.  (68%)
     for an aggregate  purchase price of $225 million in cash. The  transaction,
     subject to certain conditions including government  regulatory approval and
     the  approval  of the  minority  equity  shareholders,  is  expected  to be
     completed after December 31, 2001.







ITEM 2.

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

Results of Operations

Net sales totaled $1.9 billion for the second quarter of 2001, an increase of 5%
over sales of $1.8 billion in the prior year  quarter.  Excluding  the impact of
acquisitions, net sales for the quarter increased 3% over the prior year period.
Sales growth in the second quarter was most pronounced in the Telecommunications
Segment,  where demand for  Corning's  optical  fiber and cable  products  drove
quarter  over  quarter  segment  sales growth of 8%. Net sales for the first six
months of 2001 were $3.8 billion,  an increase of 21% over the comparable period
of 2000.  Excluding  acquisitions,  net sales for six months rose 13% over 2000.
The Telecommunications  Segment drove the increase with sales growth of 28% over
the prior year.

Corning  reported a net loss of $4,755  million  in the  second  quarter of 2001
compared to net income of $149 million in the prior year  quarter.  Diluted loss
per share was  $5.13  compared  to  diluted  earnings  per share of $0.17 in the
second quarter of 2000. The net loss for the first six months of 2001 was $4,623
million compared with net income of $226 million in 2000. Diluted loss per share
for the first  six  months of 2001 was  $5.01  per  share  compared  to  diluted
earnings per share of $0.27 in 2000.

The  quarter  and year to date  loss is  largely  attributable  to a  charge  of
approximately  $4.8  billion  ($4.7  billion  after tax) to impair  goodwill and
certain other intangible assets of the photonic technologies  business.  Further
discussion  of the  business  conditions  leading to the  impairment  charge and
measurement  of the charge is provided in Impairment of Goodwill and  Intangible
Assets on page 15.

Corning's  results  for the  second  quarter  and six  months  of 2001 were also
impacted by a restructuring charge of $8 million ($5 million after tax).

Results  for the  first  six  months  of 2000  were  impacted  by the  following
nonrecurring items:

- -    in-process  research and development (IPRD) charges of $51 million (non-tax
     deductible),  in the second  quarter of 2000 and $42 million  ($26  million
     after tax), in the first quarter of 2000,
- -    a  nonoperating  gain  related to the sale of  Quanterra  of $7 million ($4
     million  after  tax),  in  the  first  quarter  of  2000,
- -    a charge for  acquisition  costs related to the merger of Oak Industries of
     $47 million ($43 million after tax), in the first quarter of 2000, and
- -    an  after-tax  charge of $36  million  to impair  Corning's  investment  in
     Pittsburgh Corning Corporation, in the first quarter of 2000.

Amortization of purchased  intangibles  and goodwill  totaled $160 million ($109
million  after  tax) and $316  million  ($254  million  after tax) in the second
quarter  and six  months of 2001  respectively,  compared  to $49  million  ($71
million after tax) and $62 million ($81 million after tax) in the second quarter
and first six months of 2000, respectively.  These increases primarily relate to
purchase business  combinations in the  Telecommunications  Segment completed in
2000. The impairment of goodwill and other intangible assets will reduce pre-tax
amortization of purchased  intangibles and goodwill charges  approximately  $100
million per quarter for the remainder of 2001.

Corning believes  comparing its operating results on a pro forma basis excluding
impairment  and   amortization   of  purchased   intangibles  and  goodwill  and
nonrecurring  items  provides  a  better  understanding  of the  changes  in its
operating  results.  This measure is not in accordance  with, or an  alternative
for, generally accepted  accounting  principles (GAAP) and may not be consistent
with measures  used by other  companies.  Corning's pro forma results  include a
charge to write-off excess and obsolete  inventory in the photonic  technologies
business discussed in detail in the Telecommunications Review.






Pro forma net income is calculated  from net (loss) income as follows (after tax
and in millions):



                                                                             Three Months Ended            Six Months Ended

The second quarter pro forma earnings results reflect declines in performance of
all three operating segments.  Year to date  Telecommunications  and Information
Display  segments  are  performing  below  last year  while  Advanced  Materials
reflects a slight increase over 2000 year to date performance.

Outlook and Actions

Over the course of the first six months of 2001,  Corning's outlook has declined
significantly  due  to a  substantial  reduction  in  capital  spending  in  the
telecommunications  industry  and the  general  softening  of the U.S.  economy.
Corning's management believes the telecommunications industry may not show signs
of improvement  until late 2002.  Therefore,  Corning expects pro forma earnings
per share to decrease significantly from last year. As a result of lower revenue
and earnings  expectations,  Corning  announced the following actions on July 9,
2001, to adjust its cost structure:

- -    Corning  will close  three  manufacturing  facilities  within the  photonic
     technologies business by the end of 2001.
- -    Approximately 1,000 positions in photonic technologies will be eliminated.
- -    Corning  will  continue  to  evaluate  further  personnel   reductions  and
     restructuring actions in businesses other than photonic technologies.
- -    Costs  related to these  actions are expected to result in a third  quarter
     pre-tax charge of $300-400 million.

In addition,  Corning has already  undertaken  the  following  action during the
first half of 2001:

- -    In the first quarter,  Corning reduced its workforce by approximately 3,300
     permanent and temporary employees,  primarily in the photonic  technologies
     and hardware and equipment businesses. These workforce reductions comprised
     mostly hourly production workers and resulted in minimal severance charges.
     In  April,   Corning  completed  an  additional   workforce   reduction  of
     approximately  1,000  positions in photonic  technologies,  including  both
     hourly and salaried employees.  The second quarter reductions resulted in a
     restructuring charge of $8 million ($5 million after tax).
- -    Corning  decreased its capital spending forecast for 2001 from $2.5 billion
     to  approximately  $2 billion,  delaying  some  capital  expansion  to 2002
     including  its  planned  expansion  of  fiber  capacity  at  Concord,   NC.
     Construction  of a new fiber  facility in Oklahoma City, OK will be delayed
     12 to 18 months.
- -    Corning's  research and development  spending in 2001 will be approximately
     $650 million to $675 million, a decrease from an anticipated $700 million.






Corning will  continue to review its  internal  cost  structure  and monitor the
industry trends throughout 2001, which may result in additional cost improvement
measures and targeted workforce reductions.  Corning continues to believe in the
long term  demand  for  bandwidth,  optical  transparency  and the future of the
all-optical  network.  It is the foundation of Corning's optical layer strategy.
Therefore,  Corning is still  committed  to invest in new  product  development,
targeted capacity expansion and external growth.

Impairment of Goodwill and Intangible Assets

During the first half of 2001, Corning experienced a significant decrease in the
rate of growth of its  telecommunications  segment,  primarily  in the  photonic
technologies business,  due to a dramatic decline in infrastructure  spending in
the telecommunications  industry.  During the second quarter, major customers in
the photonic  technologies  business  further  reduced their order forecasts and
canceled  orders  already  placed.  Management  now  believes  that  the  growth
prospects of this business are significantly  less than previously  expected and
those of historical periods.

Corning reviews the recoverability of its long-lived assets,  including goodwill
and other intangible assets,  when events or changes in circumstances occur that
indicate the carrying value of the asset may not be recoverable.  As a result of
the business  conditions noted above,  Corning  concluded such an assessment was
required for its  photonics  business in the second  quarter.  Corning  assesses
recoverability  of the  carrying  value based upon  cumulative  expected  future
pre-tax cash flows  (undiscounted  and without interest  charges) of the related
operations.

As a  result  of this  test,  Corning  determined  that the  long-lived  assets,
including goodwill and other intangibles  acquired from Pirelli in December 2000
as well as those of the unit into which NetOptix  Corporation  (acquired in May,
2000)  has  been  integrated  were  not  recoverable.  Corning's  policy  is  to
write-down long-lived assets to fair value in such circumstances.

Management  estimated  fair value using  several  techniques.  While each method
generated  comparable fair values,  management  adjusted the assets to estimates
based on average  multiples of  forecasted  revenues and earnings of  comparable
publicly  traded  companies  with  operations  in the optical  component  market
segment.

In the second  quarter,  Corning  recorded  pre-tax charges of $4,648 million to
impair a significant  portion of goodwill and $116 million to impair  intangible
assets.  Of the total charge of $4,764  million,  $3,154 million  related to the
acquisition  of the  Pirelli  optical  components  business  and $1,610  million
related to goodwill resulting from the acquisition of NetOptix Corporation.

Operating Segments

Corning groups its products into three operating  segments:  Telecommunications,
Advanced  Materials and Information  Display.  Corning  includes the earnings of
equity affiliates that are closely associated with Corning's  operating segments
in segment net income.  Information  about the  performance  of Corning's  three
operating  segments for the second quarter and first six months of 2001 and 2000
are presented below. These amounts do not include revenues,  expenses and equity
earnings not specifically identifiable to segments.  Segment net income excludes
impairment and  amortization of purchased  intangibles  and goodwill,  purchased
IPRD costs,  one-time acquisition costs, and other nonrecurring items. Note 1 to
the  consolidated  financial  statements  includes a  reconciliation  of segment
results to Corning's net income. This measure is not in accordance with GAAP and
may not be consistent with measures used by other companies.

Corning  prepared the financial  results for its three  operating  segments on a
basis that is consistent with the manner in which Corning management  internally
disaggregates  financial  information  to assist in  making  internal  operating
decisions. Corning has allocated some common expenses among segments differently
than it would for stand alone financial  information prepared in accordance with
GAAP.  During the quarter  ended March 31, 2001,  Corning  realigned one product
line from the Advanced  Materials Segment into the  Telecommunications  Segment.
Segment  results  for  2000  have  been  restated  to  conform  to  the  current
presentation.

The  Telecommunications  Segment  produces  optical  fiber  and  cable,  optical
hardware and equipment  and photonic  modules and  components  for the worldwide
telecommunications industry.

Telecommunications Review

Sales in the Telecommunications  Segment increased 8% over the second quarter of
2000 to  approximately  $1.4 billion  compared to $1.3 billion in the prior year
quarter. Excluding the impact of acquisitions,  sales growth for the same period
in 2001 was 6%. The sales  growth in the  segment  was led  primarily  by volume
gains in the optical fiber and cable  business  offset by a decrease in sales of
photonic  technologies.  These factors were also  responsible  for the six-month
sales increase of 28% to $2.8 billion.  Excluding acquisitions,  sales increased
18% for the six months ended June 30, 2001 over the prior year  period.  Segment
net income  declined 96% to $7 million in second  quarter 2001  compared to $178
million in second  quarter  2000.  Segment net income  includes a charge of $273
million  ($184  million  after tax) to write-off  excess and obsolete  inventory
primarily  in the  photonic  technologies  business.  Segment net income for six
months  declined  33% to $196  million  compared to $293  million in 2000.  This
decrease was due to the provision for inventory and higher  spending in research
and development.

Sales in the fiber and cable business improved 30% in the second quarter of 2001
to $939  million  compared  with $722  million  in the prior year  quarter.  The
increase resulted primarily from volume gains of approximately  25%,  reflecting
continued strong demand for Corning's  single mode fiber products.  While volume
for single mode increased, volume of premium fiber and cable products, including
Corning's LEAF(R) and MetroCor(TM) optical fiber,  decreased almost 35% from the
prior year  quarter.  The average  price for  Corning's  optical fiber and cable
products  remained  relatively  stable in  comparison  with last  year's  second
quarter.

Sales in the fiber and cable  business  increased 51% to $1,814  million for the
first six months of 2001  compared  to the prior  year  period in 2000 of $1,201
million.   The  increase  in  sales  resulted   primarily  from  the  impact  of
acquisitions  and volume gains in  single-mode  fiber.  Excluding  acquisitions,
sales in the fiber and cable business  increased 40% year to date over 2000. The
average  price for  optical  fiber  and cable  products  increased  slightly  in
comparison  with last  year's  first six months as a change in mix of  customers
more than offset a lower mix of premium  products.  Corning does not expect this
upward pricing trend to continue  throughout 2001. Premium fiber as a percentage
of total fiber demand decreased from  approximately  35% in the first quarter to
approximately  25% at the end of six months and may average 20% or somewhat less
for the entire year of 2001.

Net  income  from the fiber and cable  business  increased  more than 50% in the
second  quarter and six months of 2001 compared to the prior year  periods.  The
strong performance in both periods was due to overall volume growth.






Sales in the telecommunications hardware and equipment business decreased 16% in
the second  quarter of 2001 to $231  million  compared  with $276 million in the
prior year quarter. Excluding acquisitions,  second quarter 2001 sales decreased
19% compared to the prior year quarter.  The decrease  resulted  primarily  from
lower volume of existing products including original equipment  manufacturers in
the  optical  space and optical  manufacturing  services  and a 53%  decrease in
revenues at Gilbert  Engineering  due to growing  weakness  in cable  television
industry  spending.  Sales for six months of 2001 improved 4% as sales rose from
$459  million in 2000 to $479  million in 2001.  Excluding  acquisitions,  sales
decreased 11% for the six months ended June 30, 2001 versus the comparable prior
year period. Overall,  quarterly net income decreased approximately 75% compared
to the prior  year  quarter,  primarily  due to the loss of  volume  at  Gilbert
Engineering. This also contributed to the 62% decrease in net income for the six
months ended June 30, 2001,  compared to June 30, 2000. The business has reduced
its hourly workforce by approximately 1,175 employees to date.

Sales in the photonic  technologies business decreased 33% in the second quarter
of 2001 to $158 million compared to approximately $238 million in the prior year
quarter.  This  is also a 33%  decrease  from  first  quarter  sales.  Excluding
acquisitions,  sales  decreased  38% over the  prior  year  quarter.  The  sales
decrease reflects  significant declines in orders from major customers caused by
the  decrease  in capital  spending  in the  telecommunications  industry.  This
decline in orders is a continuation of a trend begun in the first quarter. Sales
for the first six months were $394 million compared with $424 million in 2000, a
decline of 7%.  Excluding  acquisitions,  sales  decreased 13% for the first six
months of 2001 compared to the prior comparable  period. The business incurred a
significant  operating  loss in the second  quarter  and six months of 2001 as a
result of a charge for excess and  obsolete  inventory,  lower  volumes,  excess
capacity and a higher fixed cost structure.

Corning now expects revenues in photonic  technologies to be significantly below
2000 versus original expectations that revenues would increase significantly due
to  growth  in  demand  for  photonic  technology  devices.  Corning  is  making
significant  cost  and  workforce   reductions  to  reflect  the  lower  revenue
expectations.  The  business  reduced  its  workforce  through  July 31, 2001 by
approximately  3,500  employees  this year which includes  hourly,  salaried and
temporary positions.

During the second quarter, major customers in the photonic technologies business
further reduced their order forecasts and cancelled orders already placed.  As a
result,  management  determined that certain products were not likely to be sold
in their  product  life  cycle.  Corning  recorded  a  provision  for excess and
obsolete inventory,  including estimated purchase  commitments,  of $273 million
($184 million after tax) in cost of sales in the second quarter of 2001.

Corning will retain  inventory  on hand and  reserved at June 30, 2001  totaling
approximately  $70  million  and dispose of the other  inventory  reserved.  The
inventory  reserved  and  retained  represents  amounts  in excess of one year's
estimated  demand and thus will not  likely be sold.  As this  inventory  is for
newer  product  configurations,  however,  it will be retained so that it can be
available  if the market  improves  sooner than  anticipated.  Corning  plans to
physically  segregate  this reserved  inventory  and in the unlikely  event this
product is sold, Corning will fully disclose the impact on its margins.

Corning has  announced a downsizing  of the photonic  technologies  business and
will close three  manufacturing  facilities by the end of 2001. Those facilities
are as follows:

- -  Photonic Technologies Benton Park facility in Benton Township, PA,
- -  Corning Lasertron's facility in Nashua, NH, and
- -  Corning NetOptix's operation in Natick, MA.

In addition,  Corning will scale back its photonic  technologies  operations  in
Erwin Park, NY and the remainder of its photonic  facilities.  Other  previously
announced  capacity  expansions in the business have been delayed,  or postponed
until business conditions improve.






Sales in the controls and connectors business decreased 7% to $55 million in the
second  quarter of 2001 compared to $59 million in the prior year  quarter.  The
decrease  was  primarily  due to  weak  customer  demand,  particularly  in U.S.
markets.  Sales of $115  million for six months were flat  compared to six month
sales of $116 million in 2000, also due to weak customer demand. Net income from
this business was  essentially  at breakeven in the second  quarter  compared to
2000 due to lower sales volumes.  Six-month net income was up slightly  compared
to the  comparable  period  in 2000.  The  business  reduced  its  workforce  by
approximately 525 employees this year in response to current revenue forecasts.

The  optical  networking  devices  business,   which  is  developing  wavelength
management  products and optical switch modules,  began making  shipments of its
wavelength  management  products to customers in the third quarter of 2000.  The
business had sales of $10 million in the second  quarter of 2001 and $24 million
for six months.  This business is also seeing some softening in expected  demand
for its  products.  Corning is investing  significant  research and  development
spending in this business.

The Advanced  Materials Segment  manufactures  specialized  products with unique
applications  utilizing  glass,  glass  ceramic  and polymer  technologies.  The
largest  businesses  in this  segment are  environmental  technologies  and life
sciences.

Advanced Materials Review

Sales in the Advanced Materials Segment decreased slightly in the second quarter
of 2001 to $251  million  compared  to $259  million in the prior year  quarter,
primarily due to a softening market in the environmental  technologies business.
Six-month  sales for this segment are up somewhat over the comparable  period in
2000  primarily  due to  growth  in the  semiconductor  business  offset  by the
softening market in environmental technologies. Segment net income decreased 25%
in the second  quarter of 2001 as all  businesses,  excluding  life sciences and
ophthalmic  glass,  experienced  declines.  Segment  net  income  for six months
increased slightly due to an increase in life sciences partially offset by lower
margins in environmental technologies.

Sales in the  environmental  technologies  business  decreased  7% in the second
quarter  of 2001 to $96  million  compared  with $103  million in the prior year
period.  The  sales  decline  is due  to a  growing  weakness  in  sales  to the
automotive industry.  Sales in the environmental  technologies  business for the
first six months of 2001 were flat at $204 million compared with $206 million in
the comparable period of 2000 as continued strong demand for Corning's thin wall
and ultra  thin wall  products  was  offset by the  downward  trend in the North
American automotive industry.  Earnings for the second quarter and first half of
2001 were down 33% and 20%,  respectively,  primarily  due to start-up  costs in
South Africa and China,  lower sales volumes in the U.S.  automotive  market and
manufacturing  inefficiencies related to the introduction of new ultra thin wall
products.






Sales in the life sciences business of $69 million in the second quarter of 2001
increased 5% compared to second  quarter  2000 sales of $66  million.  Six-month
sales in 2001  were up 8% to $139  million  compared  with $129  million  in the
comparable period of 2000 due to increased  volumes of microplates.  Earnings in
the base business improved in the second quarter and first half of 2001 due to a
sales mix shift to higher margin  products and fixed cost  reductions.  However,
continued   investment  in  microarrays   technology   partially   offset  these
improvements  resulting  in a slight  increase  for the quarter and year to date
compared to the prior year.

Sales in Corning's other Advanced Materials  businesses  decreased slightly from
second quarter 2000 to $86 million in the second quarter of 2001 compared to $90
million in the prior year  quarter.  The  decrease  was due to  softness  in the
market for ophthalmic products. Sales for the first six months of 2001 were $190
million  compared with $176 million in the  comparable  period of 2000 for an 8%
increase.  Excluding  the impact of the  divestiture  of  Quanterra in the first
quarter of 2000,  sales  improved 12% for six months.  This  increase was led by
higher sales of high purity fused silica products in the semiconductor materials
business.  Earnings for the second  quarter were flat compared to second quarter
2000 as margins  were lower due to  production  slowdowns.  Earnings  from these
businesses  for six months 2001 more than doubled over six months 2000 primarily
due to increased  volumes in the first  quarter  partially  offset by production
slowdowns in the second quarter.

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

Information Display Review

Sales in the Information Display Segment were flat in the second quarter of 2001
at $218 million  compared to $216 million in the second  quarter 2000, as growth
in the display  technology  and precision  lens  businesses  was offset by lower
sales in the conventional video components  businesses.  Six-month sales were up
slightly as sales  increases in  precision  lens and display  technologies  were
offset by lagging sales in the conventional  video business.  Segment net income
in the second quarter and year to date 2001 was down 22% and 13%,  respectively,
compared to the prior period of 2000 due to decreased  margins,  higher spending
on research and  development  and lower equity earnings due in part to ownership
change.

Sales in the conventional video components business decreased 16% to $73 million
in second  quarter 2001 compared to $87 million in second quarter 2000 primarily
due to competitive  pricing pressure and a softening market.  These factors also
contributed to the 6% decline in sales for the six months ended June 30, 2001 at
$159 million compared to $170 million in the comparable period of 2000. Earnings
in this  business  for the quarter  decreased  28% from second  quarter  2000 as
improved  margins due to cost  reductions  were more than offset by lower equity
earnings from Samsung  Corning  Company Ltd., a manufacturer of glass panels and
funnels for  televisions  and  display  monitors.  Year to date  earnings in the
business  decreased 10% compared to the prior year primarily due to lower equity
earnings at Samsung Corning.






Sales in the display technologies  business in second quarter 2001 increased 14%
to $87 million  compared to second  quarter  2000 sales of $76  million.  Volume
increases of 45% were somewhat offset by pricing  pressure and the impact of the
weak yen on translated sales.  These factors also contributed to the 9% increase
in sales to $149 million for the six months ended June 30, 2001 compared to $137
million  for the prior  six-month  period.  Earnings  in this  business  for the
quarter were down slightly compared to the same quarter in 2000 primarily due to
lower operating margins driven by pricing pressures and increased  manufacturing
costs due to additional  capacity,  higher  spending in research and development
and lower equity  earnings at Samsung  Corning  Precision  Glass Company Ltd., a
Korean  manufacturer of liquid crystal display glass,  the result of last year's
sale by Samsung  Corning of 40% of its  interest in Samsung  Corning  Precision.
These  factors  also  contributed  to the 12%  decrease in earnings  for the six
months ended June 30, 2001 compared to the prior year six-month period.

Sales in the  precision  lens  business  increased  9% to $58  million in second
quarter  2001  compared  to $53  million in second  quarter  2000 as a result of
continued  volume  increases driven by demand for larger size televisions in the
entertainment  market sector.  This volume growth was also responsible for a 14%
increase in sales for the six-month period as sales increased to $111 million in
2001 compared with $97 million in 2000. Despite the increases in sales, earnings
for the  quarter  and year to date were lower than 2000 due to start up costs of
capacity to be online in the second half of 2001.

(Benefit) Provision for Income Tax

Corning's tax (benefit)  provision for the second quarter and six months of 2001
was impacted by the significant  impairment charge and amortization of goodwill.
Corning's effective tax rate for the second quarter and first six months of 2000
was 53.8% and 49.0%,  respectively.  Excluding  the impact of the  impairment of
goodwill  and  other   intangibles   (which  is  mostly   non-tax   deductible),
amortization  of  purchased  intangibles  and  goodwill,  purchased  IPRD costs,
one-time  acquisition costs and other  nonrecurring  items, the effective income
tax rate for the quarter and six months ended June 30, 2001, was 32.5%, which is
comparable with rates of 32.4% in both periods of 2000.

Liquidity and Capital Resources

In March 2001, Corning filed a universal shelf  registration  statement with the
Securities and Exchange  Commission that became  effective in the first quarter.
The shelf  permits the  issuance of up to $5 billion of various  debt and equity
securities.

Corning's  working capital decreased from $2,685 million at December 31, 2000 to
$2,183  million  at June 30,  2001.  The  ratio of  current  assets  to  current
liabilities  was 2.2 at June 30,  2001  compared  to a  current  ratio of 2.4 at
December 31, 2000.  The decrease in working  capital is due primarily to capital
spending.  Corning's  long-term debt as a percentage of total capital  increased
from 27% at December  31, 2000 to 39% at June 30, 2001 due to the  reduction  in
shareholders'  equity  arising  from the $4.8 billion  impairment  charge in the
second quarter.

On July 9, 2001,  in  conjunction  with  Corning's  announcement  of the special
charges described earlier, Standard and Poor's (S&P) lowered Corning's long-term
credit rating from A to A- and its  short-term  rating from A-1 to A-2. S&P also
maintained  Corning on Negative  Outlook  status.  The  company's  ratings  from
Moody's and Fitch IBCA were unaffected by the announcement, though in both cases
the outlook was changed  from Stable to Negative.  The combined  effect of these
actions is not material to Corning's liquidity profile.

Commercial  paper  borrowings  outstanding at June 30, 2001 totaled $274 million
with a weighted average maturity of 36 days.  Corning's commercial paper program
is supported by a previously  disclosed  $2 billion  revolving  credit  facility
expiring in 2005.  Corning is not in the  commercial  paper  market to fund cash
requirements, but rather to maintain a presence in the market.

Corning  believes  that its  financial  condition  is strong  and that its cash,
short-term  investments,  operating cash flows, access to equity capital markets
and borrowing capacity, collectively, provide adequate resources to fund ongoing
operating  requirements and future capital expenditures related to the expansion
of existing businesses and acquisitions.






Cash Flows

Cash and  short-term  investments  at June 30, 2001  decreased from December 31,
2000 by $483 million.  This decrease is the result of investing activities which
used cash of $1,284 million offset by operating  activities which generated cash
of $690 million and financing activities which provided cash of $126 million.

Net cash provided by operating activities was $690 million during the six months
ended June 30, 2001  compared  with cash  provided of $505 million for the prior
year period.  This trend is primarily due to increased  operating  results after
adjustment for depreciation,  amortization of purchased intangibles and goodwill
along with large  noncash  charges  including  the  impairment  of goodwill  and
purchased  intangibles  and the provision for  inventory  partially  offset by a
larger investment in working capital during 2001.

Net cash used in investing  activities amounted to $1,284 million during the six
months ended June 30, 2001 compared with $1,737 million in the prior year period
as higher  capital  spending  was more than offset by a decrease in  acquisition
activity.

Corning continues to invest  significant cash in capacity  expansions to support
growth in  operations.  Capital  spending for the six months ended June 30, 2001
totaled  $1,155  million  compared to $563 million in the prior year period.  As
disclosed in the first quarter Form 10-Q,  Corning revised its capital  spending
plan due to the decrease in  forecasted  revenues and profits for 2001.  Corning
still  expects its capital  spending  for the full year to be in the range of $2
billion.

Net cash provided by financing activities was $126 million during the six months
ended June 30, 2001 compared  with cash provided of $2,337  million in the prior
year  period.  The  substantial  decrease  is due  primarily  to the  timing  of
financing  transactions in 2000 that included an equity offering which generated
cash  proceeds of $2.2  billion and the  euro-debt  offering  which  provided an
additional  $485  million in 2000.  These  proceeds  were  largely  used to fund
acquisitions.

Dividends  paid to common  shareholders  for the second  quarter  and six months
totaled $56 million and $112  million,  respectively,  compared with $52 million
and $102 million in the same periods of 2000. On July 9, 2001,  Corning's  board
of  directors  announced  that the  company  is  discontinuing  the  payment  of
dividends on its common stock and will reinvest all cash  generated by Corning's
businesses in future growth.

In Process Research and Development

On December 12, 2000,  Corning  completed the  acquisition of Pirelli's  optical
components and devices business based in Milan, Italy. For a complete history of
the  acquisition see Corning's Form 10-K for 2000. This business had significant
research and development  projects ongoing at the time of the acquisition and as
a result,  12 of these  projects were valued as IPRD  projects.  Those  projects
included  development of submarine  products which consisted of pump laser chips
and modules as well as gratings.  At the time of  acquisition  Corning  recorded
non-tax deductible charges of $26 million and $17 million,  respectively for the
submarine and grating projects.

As part of the  downsizing of the photonic  technologies  business  announced on
July 9, 2001,  Corning will abandon the projects  underway  related to submarine
products and gratings. This action will not have a material impact to cash flow,
or the results of operations.

New Accounting Pronouncements

On July 20, 2001, the Financial  Accounting  Standards Board issued Statement of
Financial Accounting Standards (FAS) No. 141 "Business Combinations" and No. 142
"Goodwill  and Other  Intangible  Assets".  Among other  provisions,  all future
business  combinations  will be  accounted  for  using  the  purchase  method of
accounting  and the use of the  pooling-of-interest  method  is  prohibited  for
transactions initiated after July 1, 2001. In addition,  goodwill will no longer
be amortized but will be subject to impairment tests at least annually.  FAS 142
will be  effective  for Corning on January 1, 2002.  At June 30,  2001  goodwill
approximated  $1.9  billion.  Goodwill  amortization  was $148  million and $289
million for the three and six months ended June 30, 2001, respectively.

                           Part II - Other Information

ITEM 1.  LEGAL PROCEEDINGS

There  are  no  pending  legal  proceedings  to  which  Corning  or  any  of its
subsidiaries  is a party or of which any of their  property is the subject which
are material in relation to the consolidated financial statements.

Environmental Litigation. Corning has been named by the Environmental Protection
Agency under the  Superfund  Act, or by state  governments  under  similar state
laws, as a potentially  responsible  party at 12 active  hazardous  waste sites.
Under the  Superfund  Act, all parties who may have  contributed  any waste to a
hazardous  waste site,  identified  by such  Agency,  are jointly and  severally
liable  for the cost of  cleanup  unless  the  Agency  agrees  otherwise.  It is
Corning's  policy to accrue for its  estimated  liability  related to  Superfund
sites and other  environmental  liabilities related to property owned by Corning
based on expert analysis and continual  monitoring by both internal and external
consultants.  Corning has accrued  approximately  $23 million for its  estimated
liability for environmental  cleanup and litigation at June 30, 2001. 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.

Dow Corning Bankruptcy. Corning and The Dow Chemical Company each own 50% of the
common stock of Dow Corning  Corporation.  On May 15, 1995,  Dow Corning  sought
protection  under the  reorganization  provisions  of  Chapter  11 of the United
States  Bankruptcy  Code.  The  bankruptcy  proceeding  is pending in the United
States Bankruptcy Court for the Eastern District of Michigan,  Northern Division
(Bay City,  Michigan).  The bankruptcy filing stayed the prosecution against Dow
Corning of  approximately  19,000  breast-implant  product  liability  lawsuits,
including  45  class  actions.  In 1998,  Dow  Corning  and the  Tort  Claimants
Committee engaged in extended  negotiations and reached certain compromises.  On
November 8, 1998, Dow Corning and the Tort Claimants  Committee  jointly filed a
revised Plan of Reorganization (Joint Plan). Following a favorable vote from all
but four classes of  creditors,  a hearing to confirm the Joint Plan was held in
mid 1999. On November 30, 1999, the Bankruptcy Court entered an order confirming
the Joint Plan and indicated  that certain  written  opinions  would follow.  On
December  21, 1999,  the  Bankruptcy  Court issued an opinion that  approved the
principal  elements  of the  Joint  Plan with  respect  to tort  claimants,  but
construed  the Joint Plan as  providing  releases for third  parties  (including
Corning and Dow Chemical as  shareholders)  only with respect to tort  claimants
who voted in favor of the Joint  Plan.  A number of parties  opposing  the Joint
Plan filed appeals on a variety of grounds to the United States  District  Court
for the  Eastern  District  of  Michigan.  Dow  Corning  and the Tort  Claimants
Committee  filed a notice of appeal  seeking  review of the ruling  limiting the
scope of the  shareholder  releases.  On November 13, 2000,  the District  Court
entered an Order  affirming  the  Bankruptcy  Court's  November  30,  1999 Order
confirming the Joint Amended Plan and reversing the Bankruptcy  Court's December
21, 1999 Opinion on the release and injunction provisions.  On February 5, 2001,
the District Court denied a Motion for Reconsideration. Approximately 20 appeals
from the  District  Court's  Order are  pending  in the Sixth  Circuit  Court of
Appeals,  which is expected to rule in late 2001.  Further  appellate  activity,
which may include petitions for review by the U.S. Supreme Court,  could delay a
final  judgment  until late 2002 or  possibly  into 2003.  After all appeals are
exhausted,  if the  Joint  Plan is  upheld  but  the  shareholder  releases  are
effective only for those voting in favor of the Joint Plan, Corning would expect
to defend any  remaining  claims  against it on the same  grounds  that led to a
series of orders and  judgments  dismissing  all claims  against  Corning in the
federal courts and the state courts as described  under the heading Implant Tort
Lawsuits  immediately  hereafter.  With respect to the possibility of additional
direct  or  indirect  claims  against  Corning  if the  full  releases  are  not
reinstated  in the Joint Plan,  management  believes that such claims 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.  Dow  Corning  proposes  to  provide  the
required funding over the 16 year period through a combination of cash, proceeds
from  insurance,  and cash flow from  operations.  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 the  issuance  of senior  notes,  to its  commercial
creditors.  If and when Dow Corning emerges from bankruptcy,  Corning expects to
resume the  recognition  of equity  earnings from Dow Corning.  Corning does not
expect to receive dividends from Dow Corning in the foreseeable future.






Implant Tort Lawsuits. Corning and Dow Chemical, the shareholders of Dow Corning
Corporation,  have been  named in a number of state and  federal  tort  lawsuits
alleging  injuries  arising  from Dow  Corning's  implant  products.  The claims
against  the  shareholders  allege a variety of direct or  indirect  theories of
liability.  From 1991 through June 30, 2001,  Corning was named in approximately
11,470  state and  federal  tort  lawsuits,  some of which  were  filed as class
actions or on behalf of multiple claimants. 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 1993,
Corning obtained an  interlocutory  order for summary  judgment,  which was made
final in April 1995,  dismissing Corning 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. The District Court entered several orders
directing  that  Corning  be  dismissed  from  each  case  pending  in or  later
transferred  to the  Northern  District of Alabama  after Dow Corning  filed for
bankruptcy protection.  In state court legislation,  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. On July
30, 1997,  the  judgment in  California  became final when the Supreme  Court of
California  dismissed  further review as to Corning.  In Louisiana,  Corning was
awarded summary  judgment  dismissing all claims by plaintiffs and a cross-claim
by Dow  Chemical on February 21, 1997.  On February 11, 1998,  the  intermediate
appeals court in Louisiana  vacated this  judgment 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.  In the fourth  quarter  of 1997,  Corning  moved for  summary
judgment in the  Michigan  Federal  Court to dismiss  these  remaining  cases by
plaintiffs  as well as the third party  complaint  and all  cross-claims  by Dow
Chemical. 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 case. 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
and were damaged when  Corning's  stock price declined in January 1992 after the
Food and Drug Administration  (FDA) requested a moratorium on Dow Corning's sale
of silicone gel implants. No amount of damages is specified in the complaint. In
1997, the Court  dismissed the individual  defendants from the case. In December
1998,  Corning filed a motion for summary  judgment  requesting  that all claims
against  it  be  dismissed.   Plaintiffs   requested  the  opportunity  to  take
depositions  before  responding  to the motion for summary  judgment.  The Court
permitted limited additional  discovery of certain Dow Corning,  Corning and Dow
Chemical officers and directors.  These depositions were completed in the second
quarter of 1999. On September 23, 1999, the Court granted in part the request by
plaintiffs  for certain  additional  documentary  discovery.  In April 2000, the
District Court ordered two additional depositions, one of which would be that of
Dow  Corning's  former  General  Counsel.  Dow Corning filed a petition with the
United States Court of Appeals for the Second  Circuit  seeking relief from this
Order.  The Second  Circuit ruling is expected in the third quarter of 2001. The
discovery process is continuing and the Court has set no schedule to address the
still pending  summary  judgment  motion.  Corning intends to continue to defend
this  action  vigorously.  Based  upon  the  information  developed  to date and
recognizing  that the outcome of litigation is  uncertain,  management  believes
that the possibility of a materially adverse verdict is remote.

Shin Etsu Quartz  Products  Company.  In July 1999 and February 2000,  Shin Etsu
Quartz  Products  Company  filed two patent suits in Japan  against  Corning for
alleged patent  infringement of two patents  relating to the properties of fused
silica materials used in the optical  components of stepper machines.  The suits
request  damages and an injunction  preventing  sales of infringing  products in
Japan. Corning has denied infringement,  has argued that the patents are invalid
or  unenforceable,  and has filed a separate  action to invalidate the second of
the two patents. In June 2001, the Japanese court ordered settlement discussions
involving both patents in suit.  Corning and Shin Etsu are currently involved in
these discussions in an effort to reach an amicable resolution.  Corning intends
to  defend  these  suits  vigorously.   While  recognizing  that  litigation  is
inherently  uncertain,  based upon the information developed to date, management
believes that Corning has good defenses to Shin Etsu's claims.






Hereaus  Quarzglass GmbH. In July 2001,  Hereaus  Quarzglass GmbH filed a patent
infringement suit in Germany against Corning for alleged patent  infringement of
a European patent  relating to certain  properties of fused silica glass used in
the optical  components of stepper  machines.  The suit requests damages and for
Corning to refrain  from  importing or selling  infringing  products in Germany.
Since  receiving the  complaint,  Corning is in  discussions  with Hereaus in an
effort to reach an amicable  resolution.  Management  believes  that the Hereaus
patent is either not  infringed or is invalid.  Management is prepared to defend
this  action  vigorously  and,  recognizing  that the outcome of  litigation  is
uncertain, believes it has strong defenses to the Hereaus claims.

Sumitomo  Electric   Industries,   Inc.  In  December  2000,  Sumitomo  Electric
Industries,  Inc. served a patent  infringement  complaint in the U.S.  District
Court in North  Carolina  which asserts that Corning has infringed four Sumitomo
U.S.  patents  relating to optical  fiber.  The  complaint  also  asserts that a
Corning patent relating to optical fiber was invalid.  The suit seeks damages in
an unspecified amount for the alleged  infringement of the Sumitomo patents,  an
injunction restraining  infringement,  and a declaration that the Corning patent
is invalid.  Since filing the complaint,  Corning has met with  Sumitomo.  In an
effort to reach an amicable resolution,  these discussions continue.  Management
believes that the four Sumitomo  patents are either not infringed or are invalid
and  there  is no basis  for a  holding  that the  Corning  patent  is  invalid.
Management is prepared to defend this action  vigorously and,  recognizing  that
the outcome of  litigation  is  uncertain,  believes  it has strong  defenses to
Sumitomo's claims.

Pittsburgh Corning Corporation. Corning and PPG Industries, Inc. each own 50% of
the capital stock of Pittsburgh Corning Corporation (PCC). 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
240,000  open  claims.  At the time of its  Chapter  11  filing,  PCC sought and
obtained a  temporary  restraining  order and filed a motion  for a  preliminary
injunction   against  the  prosecution  of  asbestos  actions  against  its  two
shareholders to afford the parties a period of time (the "Injunction Period") in
which to  negotiate  a plan of  reorganization  for PCC.  On April 4, 2001,  the
Bankruptcy  Court  extended  the  exclusive  period  for  PCC to  file a plan of
reorganization  (the "Exclusivity  Period") until July 9, 2001, and extended the
Injunction Period to August 23, 2001. At a July 25, 2001 hearing, the Bankruptcy
Court  entered an order upon  consent of the parties  extending  the  Injunction
Period to November 30, 2001 and terminating the  Exclusivity  Period.  Under the
terms of the  Bankruptcy  Court's April 4, 2001 Order,  PCC, PPG  Industries and
Corning will have 90 days following  expiration of the Injunction Period to seek
removal and transfer of stayed cases that have not been resolved  through a plan
of reorganization.  As a result of PCC's bankruptcy filing,  Corning recorded an
after tax  charge of $36  million  in the first  quarter  of 2000 to impair  its
entire investment in PCC and discontinued recognition of equity earnings. At the
time PCC filed for bankruptcy protection, there were approximately 12,400 claims
pending against Corning alleging various theories of liability based on exposure
to PCC's asbestos products. These cases are stayed pursuant to the injunction of
the bankruptcy court.  Before PCC filed for bankruptcy  protection,  Corning was
dismissed  from similar  claims as cases  against PCC  proceeded  to trial.  The
Chapter 11 filing may lead to  additional  claims  against  Corning with related
costs of defense,  charges and expenses.  Although the outcome of litigation and
the  bankruptcy  case  is  uncertain,  management  believes  that  the  separate
corporate status of PCC will continue to be upheld.  Management is continuing to
investigate  Corning's  options for  defending  claims  against it,  which might
include  vigorously  defending  itself  on all  fronts  or  exploring  a  global
settlement  through the  bankruptcy  process.  It is probable that there will be
intensive negotiations  throughout the third quarter of 2001 concerning terms of
PCC's plan of reorganization,  including whether or not Corning and its insurers
may participate by making a contribution  in exchange for a release.  Management
cannot  estimate  the  probability  that  Corning  will be able to secure such a
release upon terms and conditions  satisfactory to Corning and its insurers. The
range of cost for these options (net of  insurance)  cannot be estimated at this
time. Although asbestos litigation is inherently  difficult,  and the outcome of
litigation  is  uncertain,  management  believes  these matters will be resolved
without a materially adverse impact on Corning's financial position.






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.  Corning  has denied  that the  coatings  produced  by  NetOptix or its
subsidiaries  caused the damage  alleged in the  complaint or that it is legally
liable for any damages which Astrium may have experienced.  Formal discovery has
just  begun,  no  depositions  have  been  taken,  and it is too early to form a
definitive  opinion  about  the  outcome  of  the  litigation.  Based  upon  the
information  developed to date and recognizing that the outcome of litigation is
uncertain,  management believes that there are good defenses to these claims and
believes they will be resolved  without  material impact on Corning's  financial
statements.
