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 third  quarter  and first  nine  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 actions, 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  transactions  listed  below  were or will be  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.

     Lucent Technologies
     -------------------
     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.  (56%) 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 in the first half of 2002. On August 16, 2001,  Corning completed
     an equity  offering  of  approximately  14 million  shares of common  stock
     generating net proceeds to Corning of approximately  $225 million which are
     expected to be used to finance this transaction.

     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  approximately  two 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)  Restructuring Actions
     During the first half of 2001,  Corning  eliminated  4,300  positions  with
     minimal   costs  and  recorded  an  $8  million  ($5  million   after  tax)
     restructuring charge in the second quarter.

     In the third quarter of 2001,  Corning  approved and began executing formal
     plans to close three manufacturing  facilities in the photonic technologies
     business and downsize its  workforce,  primarily in the  Telecommunications
     Segment prior to year end. As a result of these actions, Corning recorded a
     total charge of $339 million  ($222  million  after-tax)  which  includes a
     restructuring charge of $103 million and a charge to impair property, plant
     and equipment of $236 million.

     Restructuring Charges
     ---------------------
     The third quarter restructuring charge of $103 million includes $71 million
     of employee related separation costs (including  curtailment losses related
     to pension and  postretirement  health care plans) and $32 million in other
     exit  costs  (principally  lease  termination  and  contract   cancellation
     payments).   The  plans  entail  the  elimination  of  approximately  3,700
     positions worldwide, comprised of 2,350 hourly employees and 1,350 salaried
     employees.  Employees have been informed of the  restructuring  initiatives
     and benefits  available to them under  applicable  benefit plans or related
     contractual   provisions.   These  benefits   include   separation,   early
     retirement,  and social plan programs. Corning expects to pay approximately
     $97 million in cash related to these restructuring  plans. During the third
     quarter of 2001, Corning paid employee  separation costs of $12 million and
     other exit costs of $3 million.  As of September  30,  2001,  approximately
     2,500 of the 3,700 employees had been separated under the plans.

     Impairment of Property, Plant and Equipment
     -------------------------------------------
     Corning has evaluated the carrying  value of the  long-lived  assets in the
     businesses taking restructuring actions. The carrying value of a long-lived
     asset is considered impaired when the anticipated  separately  identifiable
     undiscounted cash flows from that asset are less than the carrying value of
     the asset.  Corning  recorded  $236 million to impair  property,  plant and
     equipment  relating to facilities to be shutdown or disposed,  primarily in
     the photonic technologies  business.  The impairment losses were determined
     based on the amount by which the  carrying  value  exceeded the fair market
     value of the asset.

     Subsequent Actions
     ------------------
     In the fourth quarter of 2001, Corning expects to undertake further actions
     that will result in additional charges in the range of $550 million to $650
     million in the fourth quarter.  Corning will offer certain employees in the
     United  States a voluntary  early  retirement  program.  In addition to the
     third quarter plant  closings,  Corning will close or  consolidate  several
     other  manufacturing  locations  as  well  as  smaller  businesses  in  the
     Telecommunications  and Advanced Materials  Segments.  As a result of these
     actions,  Corning expects to eliminate an additional 4,000 positions across
     the company bringing the total positions eliminated to approximately 12,000
     for the full year ended December 31, 2001.

(4)  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 photonic  technologies
     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.

(5)  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.

(6)  (Loss) Earnings Per Common Share
     A  reconciliation  of the  basic  and  diluted  (loss)  earnings  per share

     Diluted loss per share for the quarter and nine months ended  September 30,
     2001  exclude  potentially  dilutive  securities  due to the  anti-dilutive
     effect they would have had if converted. Those securities consisted of four
     million and eight 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.





     Common  dividends of $112 million were declared in the first nine months of
     2001.  On  July  9,  2001,  Corning  announced  it  was  discontinuing  the
     declaration and payment of future  dividends on its common stock.  The last
     dividend  paid was on June 29,  2001.  Common  dividends of $53 million and
     $155  million were  declared in the third  quarter and first nine months of
     2000.

(7)  (Benefit) Provision for Income Taxes
     Corning's  tax  benefit  for the third  quarter and nine months of 2001 was
     impacted  by  the  significant   impairment  charges  and  amortization  of
     goodwill. Corning's effective tax rate for the third quarter and first nine
     months of 2001 was 18.8% and 0.6%,  respectively.  Excluding  the impact of
     the impairment of goodwill and other  intangibles  (which is mostly not tax
     deductible),   amortization   of  purchased   intangibles   and   goodwill,
     restructuring  actions,  purchased  in-process  research  and  development,
     one-time  acquisition  costs and other  nonrecurring  items,  the effective
     income tax rate for the third  quarter  and nine  months of 2001 was 32.5%,
     which is comparable to rates of 32.4% in both periods in 2000.

(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  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. 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. Under the terms of the Bankruptcy  Court's 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.  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 fourth quarter of 2001 concerning the 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) which was confirmed by the Bankruptcy Court on
     November 30, 1999.






     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. On November 13, 2000,
     the  District  Court  entered an Order  reversing  the  Bankruptcy  Court's
     December  21, 1999  Opinion on the release and  injunction  provisions  and
     confirmed  the Joint Plan. On October 23, 2001,  the U.S.  Court of Appeals
     for the Sixth  Circuit  heard oral  arguments  on appeals  taken by foreign
     claimants, the U.S. government and certain tort claimants from the District
     Court's order. The Court of Appeals reserved  decision.  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 (and any new
     claims) on the same  grounds  that led to a series of orders and  judgments
     dismissing all claims  against  Corning in the federal courts and the state
     courts as described  under the heading  Implant  Tort  Lawsuits in Part II,
     Item 1, Legal Proceedings.  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. 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. The commercial creditors have contested
     the  Bankruptcy  Court's  disallowance  of their  claims for  post-petition
     interest at default  rates of interest,  and have  appealed to the District
     Court.  While the  amounts at issue on this appeal are subject to a variety
     of  contingencies,  it is possible  that the  aggregate  claim exceeds $100
     million.  Dow Corning is vigorously  contesting the appeal. 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 nine months ended September 30,
     2001,  after-tax income under $1 million was recorded in other expense, net
     for the ineffective portion of cash flow hedges.









ITEM 2.

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

Results of Operations

Consolidated  net sales  totaled $1.5  billion for the third  quarter of 2001, a
decrease  of 21% over sales of $1.9  billion in the prior  year  quarter.  Sales
declines occurred in all operating segments in the third quarter,  but were most
pronounced in the  Telecommunications  Segment.  Consolidated  net sales for the
first  nine  months  of 2001  were  $5.3  billion,  an  increase  of 5% over the
comparable  period of 2000.  The  Telecommunications  Segment drove the increase
with sales growth of 8% over the prior year. Excluding  acquisitions,  net sales
for nine months increased 1% compared to 2000.

Corning  reported  a net  loss of $220  million  in the  third  quarter  of 2001
compared to net income of $254 million in the prior year  quarter.  Diluted loss
per share was $0.24 compared to diluted earnings per share of $0.28 in the third
quarter  of 2000.  The net loss for the first  nine  months  of 2001 was  $4,843
million compared with net income of $480 million in 2000. Diluted loss per share
for the first  nine  months of 2001 was $5.21  per  share  compared  to  diluted
earnings per share of $0.55 in 2000.

Corning's  results for the third quarter were impacted by restructuring  actions
of $339 million ($222 million  after tax) which  included  charges for headcount
reduction,  exit costs and impairment of property, plant and equipment.  Further
discussion of the  restructuring  actions is provided in  Restructuring  Actions
beginning on page 14.

The year to date loss is largely  attributable to a charge of approximately $4.8
billion ($4.7 billion  after tax) in the second  quarter 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 16.  Year to date  results  were also  affected  by  charges  for
restructuring  actions of $347 million  ($227 million after tax) and a charge of
$273 million ($184 million after tax) in the second quarter to write-off  excess
and obsolete  inventory in the photonic  technologies  business.  This charge is
discussed in Operating Segments on page 18.

Results  for the  first  nine  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 $48 million ($83
million  after  tax) and $364  million  ($337  million  after  tax) in the third
quarter and nine  months of 2001  respectively,  compared  to $82  million  ($63
million  after  tax) and $144  million  ($144  million  after  tax) in the third
quarter and first nine  months of 2000,  respectively.  The  increase in year to
date   amortization   relates  to   purchase   business   combinations   in  the
Telecommunications  Segment completed in 2000. The second quarter  impairment of
goodwill and other intangible assets has reduced quarterly pre-tax  amortization
of purchased intangibles and goodwill charges.

Corning believes  comparing its operating results on a pro forma basis excluding
impairment and amortization of purchased intangibles and goodwill, restructuring
actions 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 the
charge to write-off excess and obsolete  inventory in the photonic  technologies
business.






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

The third quarter and nine months pro forma earnings results reflect declines in
the performance of all three operating segments.

Outlook

Over the course of the first nine months of 2001, Corning's outlook has declined
significantly, particularly in the third quarter, 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, or 2003.  Following
the 21% decline in the third quarter sales, Corning expects fourth quarter sales
to be in the range of $1 billion or down  about 50%  compared  to the prior year
period.  Therefore,  Corning  expects pro forma  earnings  per share to decrease
significantly  from last year and also  anticipates a pro forma loss of $0.20 to
$0.25 per share in the fourth  quarter.  Corning also expects to record a fourth
quarter  pre-tax  restructuring  charge  in the  range of $550  million  to $650
million . Corning has taken steps to reduce costs in light of anticipated  lower
revenues and those  actions are described in  Restructuring  Actions  below.  In
addition  to  restructuring  activities,  operating  actions  taken  include the
following:

-    Corning will idle the majority of its worldwide optical fiber manufacturing
     capacity in the fourth quarter beginning in late October with production to
     resume in 2002 when demand improves.
-    Corning decreased its capital spending forecast for 2001 to a range of $1.7
     to $1.8  billion  and  has  reduced  planned  capital  spending  in 2002 to
     approximately  $700 million.  The 2002 plan  anticipates that all expansion
     projects in the Telecommunications Segment are on hold indefinitely.
-    Corning's  research and development  spending in 2001 will be approximately
     $650 million to $675 million, a decrease from an anticipated $700 million.

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.

Restructuring Actions
Corning  has  approved  and begun  executing  several  restructuring  activities
throughout  the year.  These  activities  and the  charges  relating to them are
described below.






Q3 Actions
----------

Actions  approved and undertaken in the third quarter  related  primarily to the
Telecommunications Segment and included the following:
-    Closing of three  manufacturing  facilities  in the  photonic  technologies
     business  resulting in the elimination of approximately 800 positions.  The
     plants were closed at the end of the third quarter.
-    Elimination of  approximately  2,900  positions  worldwide in the fiber and
     cable business.  This action included a voluntary early retirement  program
     for certain employees.

As a result of these  actions,  Corning  recorded a total charge of $339 million
($222 million after tax) which includes a  restructuring  charge of $103 million
and a charge to impair property, plant and equipment of $236 million.

     Restructuring Charges
     ---------------------
     The third quarter restructuring charge of $103 million includes $71 million
     of employee related separation costs (including  curtailment losses related
     to pension and  postretirement  health care plans) and $32 million in other
     exit  costs  (principally  lease  termination  and  contract   cancellation
     payments).   The  plans  entail  the  elimination  of  approximately  3,700
     positions  in the  Telecommunications  Segment,  comprised  of 2,350 hourly
     employees and 1,350 salaried employees primarily in the U.S. Employees have
     been informed of the  restructuring  initiatives and benefits  available to
     them under  applicable  benefit  plans or related  contractual  provisions.
     These benefits include separation,  early retirement,  and social programs.
     Corning expects to pay  approximately  $97 million in cash related to these
     restructuring  plans.  During  the  third  quarter  of 2001,  Corning  paid
     employee  separation  costs  of $12  million  and  other  exit  costs of $3
     million.  As of  September  30,  2001,  approximately  2,500  of the  3,700
     employees had been separated under the plans.

     Impairment of Property, Plant and Equipment
     -------------------------------------------
     Corning has evaluated the carrying  value of the  long-lived  assets in the
     businesses taking restructuring actions. The carrying value of a long-lived
     asset is considered impaired when the anticipated  separately  identifiable
     undiscounted cash flows from that asset are less than the carrying value of
     the asset.  Corning  recorded  $236 million to impair  property,  plant and
     equipment  relating to facilities to be shutdown or disposed,  primarily in
     the photonic technologies  business. The impairment charges were determined
     based on the amount by which the  carrying  value  exceeded the fair market
     value of the asset.

Earlier Actions
---------------
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 the restructuring charge of
$8 million ($5 million after tax).

Q4 Actions
----------
On October 3, 2001,  Corning  announced that it will take further actions in the
fourth quarter. These actions include:
-    Closing or consolidating several manufacturing locations as well as smaller
     businesses in the Telecommunications and Advanced Materials Segments.
-    Discontinuing  its initiative in Corning  Microarray  Technology  products,
     part of Corning's life sciences business.
-    Reducing headcount across all businesses,  research and staff organizations
     to reduce  operating  expense in line with  reduced  revenue  expectations.
     Corning will offer certain employees a voluntary retirement incentive.

These  actions  will result in an  additional  headcount  reduction of 4,000 and
pre-tax  charges in the range of $550 to $650 million.  Corning will continue to
review its internal cost structure and monitor  industry trends which may result
in additional cost improvement measures.






In  summary,  Corning's  restructuring  actions  are  expected to total up to $1
billion in pre-tax  charges for the year ended December 31, 2001.  Approximately
one third of this total charge is expected to be paid in cash.  The total number
of positions expected to be eliminated across the company by year end is 12,000.

Corning  expects  to  begin  to  realize  savings  related  to  these  headcount
reductions in late 2001 with estimated  ongoing  annual net savings  expected to
grow in 2002 to approximately $400 million (pre-tax). These savings are expected
to be realized as  reductions  in cost of sales,  research and  development  and
selling, general and administrative expenses.

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 third quarter and first nine 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, restructuring
actions,   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.

Sales in the Telecommunications  Segment decreased 23% over the third quarter of
2000 to  approximately  $1.1 billion  compared to $1.4 billion in the prior year
quarter.  The sales decline in the segment was primarily due to volume decreases
in the photonic  technologies and hardware and equipment  businesses.  Sales for
nine-months  increased 8% to $3.9 billion as volume gains in the fiber and cable
business were offset by loss of volume in photonic technologies and hardware and
equipment.  Excluding  acquisitions,  sales were flat for the nine months  ended
September  30,  2001  compared  to the prior  year  period.  Segment  net income
declined 87% to $27 million in third  quarter  2001  compared to $203 million in
third quarter 2000 due to a loss in photonic  technologies and lower earnings in
the hardware and equipment business. Segment net income for nine months declined
55% to $223  million  compared to $496 million in 2000 as  performance  gains in
fiber and cable were offset by significant  losses in photonic  technologies and
lower performance in hardware and equipment.  Segment net income for nine months
includes a charge of $273 million ($184  million after tax) to write-off  excess
and obsolete inventory primarily in the photonic technologies business.

Sales in the fiber and cable business  decreased 2% in the third quarter of 2001
to $779 million  compared with $795 million in the prior year  quarter.  Corning
has  experienced  declining  volume in all of its fiber and cable product lines.
This decline is most pronounced for premium fiber and cable products,  including
Corning's LEAF(R) and MetroCor(TM) optical fiber which declined to approximately
10% of total volume.  The volume  decreases  were offset in part by increases in
the undersea cable business due to one contract for which shipments in the third
quarter were  significant.  The average  price for  Corning's  optical fiber and
cable  products  was  relatively  stable in  comparison  with last year's  third
quarter.

Sales in the fiber and cable  business  increased 30% to $2,593  million for the
first nine months of 2001 compared to $1,996 million in the prior year period of
2000. 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 23% year to date over 2000. The average price
for optical fiber and cable  products  remained  stable in comparison  with last
year's  first nine  months as a change in mix of  customers  more than  offset a
lower mix of premium  products.  Premium  fiber as a  percentage  of total fiber
demand was  approximately  25% for the nine months  ended  September  30,  2001,
although declining significantly after the first quarter.

Net income  from the fiber and cable  business  was down  modestly  in the third
quarter of 2001 compared to the prior year period  reflecting volume declines on
premium  products.  Net  income  for nine  months was up over 50% due to overall
volume growth in the first half of the year.  Fiber demand slowed  significantly
in  September.  In  response,  Corning  will  idle all its  fiber  manufacturing
operations  and  portions of its cable  manufacturing  facilities  in the fourth
quarter.  This  business is expected to incur a  significant  loss in the fourth
quarter. In October, Corning announced it has proposed closing its optical fiber
operations in Deeside, North Wales.






Sales in the telecommunications hardware and equipment business decreased 35% in
the third  quarter of 2001 to $187  million  compared  with $288  million in the
prior year quarter.  Excluding acquisitions,  third quarter 2001 sales decreased
38% compared to the prior year quarter.  The decrease  resulted  primarily  from
lower volumes in all existing  product lines and an approximate  50% decrease in
revenues at Gilbert  Engineering  due to growing  weakness  in cable  television
industry spending. Sales for nine months of 2001 declined 11% as sales decreased
from $747 million in 2000 to $666 million in 2001. Excluding acquisitions, sales
decreased 22% for the nine months ended September 30, 2001 versus the comparable
prior year period.  Overall,  the business incurred a small loss for the quarter
and a significant  decrease in net income for nine months,  primarily due to the
loss of volume at Gilbert Engineering.

Sales in the photonic  technologies  business decreased 75% in the third quarter
of 2001 to $69 million compared to approximately  $273 million in the prior year
quarter.  This is also a 56%  decrease  from  second  quarter  sales.  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 nine months were $463 million  compared with $697 million in 2000,
a decline of 34%.  The business  incurred a  significant  operating  loss in the
third  quarter  and nine  months  of 2001 as a result of lower  volumes,  excess
capacity,  a higher fixed cost  structure and a second quarter charge for excess
and obsolete  inventory.  Corning  expects  fourth quarter sales and earnings to
approximate third quarter results.

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 has  announced a downsizing  of the photonic  technologies  business and
will close four  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,
-    Corning NetOptix's operation in Natick, MA, and
-    Photonic   Technologies   manufacturing   and  development   operations  in
     Henrietta, N.Y.

In addition,  Corning will scale back its photonic  technologies  operations  in
Erwin Park, NY and the remainder of its photonic  facilities.  Corning is making
significant  cost  and  workforce   reductions  to  reflect  the  lower  revenue
expectations.

During the third  quarter,  Corning  learned of  potential  issues with  certain
products sold by the photonic  technologies  business which included  components
purchased  from other  suppliers.  Corning is studying the issues and evaluating
what actions,  if any, may be necessary to address these matters. It is possible
that the outcome of this evaluation will result in charges in future periods.

Sales in the controls and  connectors  business  decreased 23% to $47 million in
the third quarter of 2001 compared to $61 million in the prior year quarter. The
decrease  was  primarily  due to  weak  customer  demand,  particularly  in U.S.
markets.  Sales of $162  million  for nine  months were down 8% compared to nine
month  sales of $177  million in 2000,  also due to weak  customer  demand.  The
business  incurred a small loss in the third quarter  compared to a small profit
in 2000 mainly due to lower sales volumes.  Nine-month net income was relatively
flat compared to the same period in 2000.






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 $7 million in the third  quarter of 2001 and $31  million
for nine 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.

Sales in the Advanced  Materials  Segment  decreased 8% in the third  quarter of
2001 to $234  million  compared  to $253  million  in the  prior  year  quarter,
primarily  due to a  softening  market  in the  environmental  technologies  and
specialty  materials  businesses.  Nine-month  sales for this  segment  are flat
compared to the same period in 2000 primarily due to growth in the semiconductor
business offset by the softening market in environmental  technologies.  Segment
net income decreased 68% in the third quarter and 19% for nine months of 2001 as
all businesses, excluding life sciences, experienced declines.

Sales in the  environmental  technologies  business  decreased  11% in the third
quarter  of 2001 to $90  million  compared  with $101  million in the prior year
period. The third quarter sales decline is due to a growing weakness in sales to
the automotive  industry which began with softness in North American markets but
extended  to  global  markets  at the end of the  third  quarter.  Sales  in the
environmental  technologies business for the first nine months of 2001 were down
slightly at $294 million compared with $307 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 automotive  industry.  Earnings
for the third quarter and first nine months of 2001 were down  approximately 50%
and 30%,  respectively,  primarily  due to  start-up  costs in South  Africa and
China, lower sales volumes in the worldwide  automotive market and manufacturing
inefficiencies related to the introduction of new ultra thin wall products.

Sales in the life sciences  business of $65 million in the third quarter of 2001
increased  slightly  compared  to  third  quarter  2000  sales  of $62  million.
Nine-month  sales in 2001 were up 7% to $204 million  compared with $191 million
in the  comparable  period  of 2000 due to  increased  volumes  of  microplates.
Earnings  in the base  business  continued  to improve in the third  quarter and
first nine months 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 in earnings
for the  quarter and year to date  compared  to the prior  year.  On October 18,
2001,  Corning  announced the  discontinuation  of its  initiative in microarray
technology products.






Sales in Corning's other Advanced Materials  businesses  decreased slightly from
third  quarter 2000 to $79 million in the third  quarter of 2001 compared to $90
million in the prior year  quarter.  The  decrease  was due to  softness  in the
market for ophthalmic products and high purity fused silica. Sales for the first
nine months of 2001 were flat at $269 million  compared with $266 million in the
comparable period of 2000.  Earnings for the third quarter were flat compared to
third quarter 2000 as margins were lower due to production  slowdowns.  Earnings
from these businesses for nine months of 2001 were down  approximately  50% over
nine months of 2000 primarily due to decreased volumes and production  slowdowns
in the second and third 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.

Sales in the Information  Display Segment  decreased 22% in the third quarter of
2001 to $183 million  compared to $236 million in the third  quarter of 2000, as
all  businesses in this segment  experienced  sales  declines or remained  flat.
Nine-month  sales were down 6% as sales  increases in precision lens and display
technologies  were offset by lower  sales in the  conventional  video  business.
Segment  net income in the third  quarter and year to date 2001 was down 47% and
27%,  respectively,  compared  to the  prior  periods  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 50% to $47 million
in third quarter 2001  compared to $94 million in third  quarter 2000  primarily
due to competitive  pricing pressure and a softening market.  These factors also
contributed  to the 22%  decline in sales to $206  million  for the nine  months
ended  September 30, 2001 compared to $264 million in the  comparable  period of
2000.  Earnings for the quarter were less than 50% of earnings in third  quarter
2000 as margins  declined due to plant  shutdowns and lower equity earnings from
Samsung  Corning  Company Ltd., a  manufacturer  of glass panels and funnels for
televisions  and display  monitors.  Year to date  earnings  decreased  over 30%
compared  to the prior  year  primarily  due to weak  demand  and  lower  equity
earnings at Samsung Corning.






Sales in the display  technologies  business in third quarter 2001 decreased 10%
to $79 million compared to third quarter 2000 sales of $88 million.  Corning now
anticipates  its total volume  growth of liquid  crystal  display  glass will be
approximately 25%, which is down from previous  expectations of 35%, but in line
with overall market growth. However, a significant shift in customer demand from
Japan to Korea caused volume to increase  approximately  30% at Samsung  Corning
Precision  Glass Company Ltd., an equity  affiliate and Korean  manufacturer  of
liquid crystal display glass, and 5% in the consolidated  business.  This volume
growth,  when offset by the impact of currency  translation  and price  declines
resulted in the year to year sales decline of approximately  10%. These dynamics
also  contributed  to flat  sales  of $228  million  for the nine  months  ended
September  30, 2001  compared to $225 million for the prior  nine-month  period.
Earnings for the quarter and nine months ended September 30, 2001 were down over
40% and 20%, respectively, compared to the same periods 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.  Lower equity earnings
are also due to last  year's sale by Samsung  Corning of 40% of its  interest in
Samsung Corning Precision.

Sales in the  precision  lens  business  increased  5% to $57  million  in third
quarter  2001  compared  to $54  million  in third  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 11%
increase in sales for the nine-month  period as sales  increased to $168 million
in 2001  compared  with $151  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 new  capacity.  Consumer  spending  slowed  and  projection  TV  makers
adjusted inventory levels at the end of the third quarter. This business started
to  experience  lower sales in September  and is expecting  weakness to continue
into the fourth quarter as a result of the weak U.S. economy.

(Benefit) Provision for Income Tax

Corning's tax benefit for the third quarter and nine months of 2001 was impacted
by the significant  impairment  charges and amortization of goodwill.  Corning's
effective tax rate for the third quarter and first nine months of 2001 was 18.8%
and 0.6%,  respectively.  Excluding the impact of the impairment of goodwill and
other  intangibles  (which  is  mostly  non-tax  deductible),   amortization  of
purchased intangibles and goodwill, restructuring actions, purchased IPRD costs,
one-time  acquisition costs and other  nonrecurring  items, the effective income
tax rate for the quarter and nine months ended  September  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.  As of September 30, 2001,  Corning's  remaining capacity was $4,775
million.

Corning's  working capital decreased from $2,685 million at December 31, 2000 to
$2,142  million at September  30, 2001.  The ratio of current  assets to current
liabilities  was 2.2 at September 30, 2001 compared to a current ratio of 2.4 at
December  31,  2000.  The  decrease  in working  capital is due to cash used for
capital spending, lower inventories and an increase in loans payable.  Corning's
long-term  debt as a percentage of total capital  increased from 27% at December
31, 2000 to 39% at  September  30, 2001 due to the  reduction  in  shareholders'
equity arising from losses this year.

On August 16, 2001,  Corning  completed an equity offering of  approximately  14
million   shares  of  common  stock   generating  net  proceeds  to  Corning  of
approximately $225 million.  The proceeds will be used to finance the previously
announced  acquisition of Lucent  Technologies'  controlling equity interests in
Shanghai Fiber Optic Co., Ltd. and Beijing Fiber Optic Cable Co., Ltd.  expected
to close in the first half of 2002.

Since June 30, 2001,  Corning's credit ratings for both long and short term debt
were downgraded by Standard & Poor's (S&P),  Moody's and Fitch.  S&P also placed
Corning on Credit  Watch with  negative  implications.  Despite the  downgrades,
Corning's  credit ratings remain at investment  grade levels.  As Corning's long
term debt is at fixed interest  rates,  the downgrades  will not impact interest
expense.  Further downgrades could increase borrowing costs and affect Corning's
ability to access the commercial paper market on a consistent basis.






Commercial  paper  borrowings  outstanding  at  September  30, 2001 totaled $174
million with a weighted average maturity of 24 days.  Corning's commercial paper
program is  supported  by a previously  disclosed  $2 billion  revolving  credit
facility expiring in 2005. Corning has not borrowed against this line of credit.
This agreement contains one financial covenant requiring Corning's total debt to
total capacity ratio, as defined, to be no more than 60%. At September 30, 2001,
this ratio was 41.6%.  Corning's  debt could increase  approximately  $4 billion
within the constraints of this provision.

Corning  believes  that its  financial  condition  is strong  and that its cash,
short-term  investments,  operating  cash flows,  access to 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 September 30, 2001 decreased from December
31, 2000 by $199 million.  This  decrease is the result of investing  activities
which used cash of $1,642 million offset by operating activities which generated
cash of $1,224  million and  financing  activities  which  provided cash of $222
million.

Net cash provided by operating  activities  was $1,224  million  during the nine
months ended  September 30, 2001 compared with cash provided of $876 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,  restructuring actions and the provision for
inventory.

Net cash used in investing activities amounted to $1,642 million during the nine
months ended  September 30, 2001 compared with $2,191  million in the prior year
period  as  higher  capital  spending  was more than  offset  by a  decrease  in
acquisition activity.

Capital  spending for the nine months ended  September  30, 2001 totaled  $1,532
million compared to $976 million in the prior year period.  Capital expenditures
for the third  quarter were $377  million  compared to $413 million in the prior
year.  Corning  revised  its  capital  spending  plan  due  to the  decrease  in
forecasted  revenues and profits.  Corning now expects capital  spending for the
full year 2001 to be in the range of $1.7 to $1.8  billion  and to  decrease  to
approximately $700 million in 2002. The 2002 plan anticipates that all expansion
projects in the Telecommunications Segment are on hold indefinitely.

Net cash  provided by  financing  activities  was $222  million  during the nine
months ended September 30, 2001 compared with cash provided of $2,285 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 nine months totaled $112 million
compared with $53 million and $155 million for the third quarter and nine months
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 fuller  discussion
of the  acquisition  see  Corning's  Annual  Report on 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  identified and
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 Corning's
cash flow, or its 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 September 30, 2001 goodwill
approximated $2 billion.  Goodwill amortization was $37 million and $326 million
for the three  and nine  months  ended  September  30,  2001,  respectively.  An
assessment of the  recoverability  of goodwill  recorded on the date of adoption
must be performed within one year.  Corning has not yet completed this benchmark
assessment and has not yet  determined  whether it will impair any goodwill upon
implementation of the standard.

                           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 September 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 and  thereby  obtained a stay of  approximately  19,000
breast-implant  product liability lawsuits. On November 8, 1998, Dow Corning and
the Tort  Claimants  Committee  jointly  filed a revised Plan of  Reorganization
(Joint Plan) which was confirmed by the  Bankruptcy  Court on November 30, 1999.
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. On November 13, 2000,  the District  Court
entered an Order reversing the Bankruptcy  Court's  December 21, 1999 Opinion on
the release and  injunction  provisions and confirmed the Joint Plan. On October
23, 2001,  the U.S.  Court of Appeals for the Sixth Circuit heard oral arguments
on appeals  taken by foreign  claimants,  the U.S.  government  and certain tort
claimants  from the  District  Court's  order.  The  Court of  Appeals  reserved
decision.  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 (and any
new  claims) on the same  grounds  that led to a series of orders and  judgments
dismissing all claims against Corning in the federal courts and the state courts
as described  under the heading  Implant Tort  Lawsuits  immediately  hereafter.
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.  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.  The commercial
creditors have contested the Bankruptcy Court's disallowance of their claims for
post-petition  interest at default  rates of interest,  and have appealed to the
District  Court.  While the  amounts at issue on this  appeal  are  subject to a
variety of  contingencies,  it is possible that the aggregate claim exceeds $100
million.  Dow  Corning is  vigorously  contesting  the  appeal.  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.  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.  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. 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. 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 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. In late September  2001, Shin Etsu withdrew from
these  discussions  and has requested  that the Court rule on the matters before
it. 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.
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 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.
Corning and Sumitomo have had a series of discussions in the third quarter in an
effort to resolve  this  litigation,  and  Corning's  management  believes it is
probable  that a  settlement  agreement  will be reached in the fourth  quarter.
Management  expects the terms of settlement  will not have a material  impact on
Corning's results in any quarter.

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. 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.  Under  the terms of the  Bankruptcy
Court's  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.  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 fourth 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.
