CORNING INCORPORATED AND SUBSIDIARY COMPANIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1)  Information by Operating Segment
     Information about the performance of Corning's three operating segments for
     the first  quarter  of 2001 and 2000 are  presented  below.  These  amounts
     exclude   revenues,   expenses  and  equity   earnings   not   specifically
     identifiable  to  segments.  Segment net income  excludes  amortization  of
     purchased  intangibles  and  goodwill,  purchased  in-process  research and
     development (IPRD) 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.  Based upon the average
     closing price of Corning common stock for a range of days  surrounding  the
     announcement and adjusted for a discount  commensurate with restrictions on
     the shares issued,  the recorded purchase price  approximated $160 million.
     The excess of the purchase  price over the estimated fair value of tangible
     assets acquired was allocated to goodwill.  Goodwill of approximately  $155
     million is being amortized on a straight-line basis over 15 years.

     At March 31, 2001,  approximately  29 million  convertible  shares from the
     subordinated  notes and the zero  coupon  convertible  debentures  were not
     included  in the  calculation  of  diluted  earnings  per  share due to the
     anti-dilutive  effect  they would  have had if  converted.  Also,  the 2001
     computation  of diluted  earnings per share  excluded 36 million  potential
     common shares since the option  exercise price was greater than the average
     market price of the common shares for the period.

     At March 31, 2000,  approximately eight million convertible shares from the
     preferred  stock  and the  subordinated  notes  were  not  included  in the
     calculation of diluted earnings per share due to the  anti-dilutive  effect
     they would have had if converted.

     Common  dividends of $56 million were declared in the first quarter of 2001
     compared with $50 million for the same period in 2000.  Dividends per share
     were $0.06 in each period.

(4)  Taxes on Income
     Corning's  effective  income tax rate for the first quarter ended March 31,
     2001 was 51.1%,  an increase over the 2000 rate of 40.1%.  The increase was
     primarily  due  to  the  large  amounts  of  non-tax  deductible  purchased
     intangibles  and  goodwill  acquired  from  acquisitions  arising  in 2000.
     Excluding  the impact of the  amortization  of  purchased  intangibles  and
     goodwill,  purchased  IPRD  costs,  one-time  acquisition  costs  and other
     nonrecurring  items, the effective income tax rate was approximately  32.5%
     for the quarters ended March 31, 2001 and 2000.

(8)  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
     the period from December 1996 through  February  1998,  Dow Corning filed a
     plan of reorganization  and two amended plans, each of which was opposed by
     creditor  representatives.  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).  The Joint Plan and
     related  disclosure  materials were mailed to claimants for their approval.
     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.  Corning and Dow
     Chemical  filed separate  notices of appeal on this issue.  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,  confirming  that the Litigation  Facility under the Joint
     Plan is the  defendant in place of Dow Corning,  Corning and Dow  Chemical,
     and that  Corning  and Dow  Chemical  are not named  defendants  for direct
     claims.  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. 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  will likely begin to
     recognize  equity  earnings  from Dow  Corning.  Corning does not expect to
     receive dividends from Dow Corning in the foreseeable future.






(9)  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.  By the first  quarter of 2000,  PCC  incurred
     adverse verdicts in five trials involving 19 claimants.  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.  On April 4,  2001,  the
     Bankruptcy   Court   extended  the  period  for  PCC  to  file  a  plan  of
     reorganization  until July 9, 2001.  The  preliminary  injunction  has been
     extended  by court  order to August  23,  2001 to  enable  the  parties  to
     negotiate  a  plan  of  reorganization  for  PCC.  Upon  expiration  of the
     injunction,  PCC,  PPG  Industries  and  Corning  will have 90 days 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,  all of
     which 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 second  quarter of 2001  concerning  terms of
     PCC's  plan  of  reorganization,  including  whether  or  not  Corning  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.  The range of
     cost for these options (net of insurance) cannot be estimated at this time,
     although  management  believes  these  matters  will be resolved  without a
     materially adverse impact on Corning's financial position.

(10) 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 three  months ended March 31,
     2001,  an  after-tax  charge of $3 million  was  recorded  in other  income
     (expense), net for the ineffective portion of cash flow hedges.

     Foreign Currency Risk
     ---------------------
     Corning  operates and conducts  business in many  foreign  countries.  As a
     result,  there is  exposure  to  potentially  adverse  movement  in foreign
     currency rate changes.  Corning  selectively  enters into foreign  exchange
     forward and option contracts with durations  generally 12 months or less to
     reduce its  exposure to  exchange  rate risk on foreign  source  income and
     purchases.  The objective of these contracts is to neutralize the impact of
     foreign currency exchange rate movements on Corning's operating results.






     The derivative  contracts require Corning to exchange,  or give Corning the
     option to exchange  currencies at rates agreed upon at the inception of the
     contract.  The hedge  contracts  reduce the  exposure  to  fluctuations  in
     exchange  rate  movements  because  the gains and  losses  associated  with
     foreign  currency  balances and  transactions are generally offset with the
     gains and losses of the hedge contracts. Because the impact of movements in
     foreign exchange rates on the hedge contracts offsets the related impact on
     the  underlying  items  being  hedged,  these  financial  instruments  help
     alleviate  the risk that might  otherwise  result  from  change in currency
     exchange rate fluctuations.

     The forward and option  contracts  are  designated  as cash flow hedges and
     accordingly,  when effective,  any changes in fair value on these contracts
     are reported in other comprehensive  income.  Realized gains and losses for
     the effective portion are recognized in earnings when the underlying hedged
     transaction affects earnings.







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 first quarter of 2001, an increase of 42%
over sales of $1.35 billion in the prior year  quarter.  Excluding the impact of
acquisitions,  net sales  increased  26% over the first  quarter of 2000.  Sales
growth  in the  first  quarter  was most  pronounced  in the  Telecommunications
Segment, where the impact of acquisitions and demand for Corning's premium fiber
and cable and photonics products drove quarter over quarter segment sales growth
of 58%.

Corning's  net income  totaled  $132  million in the first  quarter of 2001,  an
increase  of 71% from  the  prior  year  quarter.  Diluted  earnings  per  share
increased  55% to $0.14 per share in the first  quarter of 2001  compared to the
prior year quarter.  The percentage  increase in earnings per share is less than
the  percentage  increase in net income due to the  issuance of common stock for
acquisitions and related financing transactions in 2000.

Corning's  results for the first  quarter of 2001 did not  include any  material
nonrecurring  items,  however  2000's first  quarter  results  were  impacted by
several nonrecurring items:

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

Amortization of purchased  intangibles  and goodwill  totaled $156 million ($145
million  after tax) in first  quarter 2001  compared to $13 million ($10 million
after tax) in first quarter 2000.  This increase  primarily  relates to purchase
business combinations in the Telecommunications Segment completed in 2000.

Corning believes  comparing its operating results on a pro forma basis excluding
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.

The first  quarter 2001 pro forma  results  reflect  double-digit  growth in the
Telecommunications  and Advanced Materials Segment while the Information Display
Segment remained relatively flat.

Outlook

Over  the  course  of  the  first  quarter,   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. As a
result  of these  factors,  Corning  now  expects  revenue  growth  of 9% to 12%
compared to previous  expectations  of 20% to 25% and expects pro forma earnings
per  share to  decrease  20% to 25% from  2000.  As a  result  of lower  revenue
expectations,  Corning  has  taken the  following  actions  to  adjust  its cost
structure:

 .    Through the end of 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  announced  an
     additional workforce reduction of approximately 1,000 positions in photonic
     technologies, including both hourly and salaried employees.
 .    Corning is  decreasing  its capital  spending  forecast  for 2001 from $2.5
     billion to  approximately  $2 billion,  delaying some capital  expansion to
     2002.
 .    Corning's  research and development  spending in 2001 will be approximately
     $650 million to $675 million,  a decrease from an anticipated $700 million,
     but substantially over 2000's $540 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.  As a result of actions taken in the
second quarter, Corning may record a restructuring charge in the second quarter.
Corning  is still  committed  to invest  in new  product  development,  targeted
capacity expansion and external growth.

Business Combinations

On March 16, 2001,  Corning completed the acquisition of Tropel  Corporation 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 acquisition
was accounted for as a purchase and is reported in the  semiconductor  materials
business in the Advanced Materials Segment.

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 first  quarter of 2001 and 2000 is presented  below.
These  amounts  do not  include  revenues,  expenses  and  equity  earnings  not
specifically identifiable to segments.  Segment net income excludes 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.

First quarter

Sales in the Telecommunications  Segment increased 58% over the first quarter of
2000 to  approximately  $1.4 billion  compared to $905 million in the prior year
quarter.  Excluding  acquisitions,  sales growth for the same period in 2001 was
35%.  The sales  growth in the segment was led  primarily by volume gains in the
optical  fiber and cable,  hardware  and  equipment  and  photonic  technologies
businesses.  Segment net income rose 64% to $189  million in first  quarter 2001
compared to $115  million in first  quarter  2000.  The  increase in segment net
income  was  primarily  due to  improved  gross  margins  in the fiber and cable
business that more than offset a margin decline in photonic technologies.

Sales in the fiber and cable business  improved 83% in the first quarter of 2001
to $875  million  compared  with $479  million  in the prior year  quarter.  The
increase in sales resulted  primarily from the impact of acquisitions and strong
volume  gains.  Approximately  $143 million of the increase in optical fiber and
cable sales  resulted  from the  acquisition  of the  remaining  50% interest in
Siecor GmbH and the cabling  business  previously  owned by Siemens in the first
quarter of 2000.

Excluding  the  impact  of these  acquisitions,  sales in the  fiber  and  cable
business  increased  53% for the quarter due to volume gains of 30%,  reflecting
continued strong demand for Corning's premium fiber products.  Volume of premium
fiber and cable products,  including Corning's LEAF(R) and MetroCor(TM)  optical
fiber,  increased almost 50% over the prior year quarter.  The average price for
Corning's  optical fiber and cable  products  increased in comparison  with last
year's  first  quarter  due to both the mix of  customers  and a  higher  mix of
premium products. Corning does not expect this trend to continue throughout 2001
as premium  fiber as a  percentage  of total  fiber  demand will  decrease  from
approximately 35% in the first quarter to 25% for the entire year of 2001.

Net  income  from the fiber and cable  business  more than  doubled in the first
quarter of 2001 compared to the prior year quarter.  The strong  performance was
due to volume  growth in both  high-data  rate and single mode  products and the
continued shift to a higher premium product mix.






Sales in the telecommunications hardware and equipment business increased 35% in
the first  quarter of 2001 to  approximately  $248  million  compared  with $183
million in the prior year quarter.  Excluding  acquisitions,  first quarter 2001
sales  increased  9% compared  to the prior year  quarter.  The modest  increase
resulted  primarily  from higher  volume of existing  products  including  cable
assemblies, fiber optic hardware and high speed internet connections,  offset in
part by price declines and a 47% decrease in revenues at Gilbert Engineering due
to growing weakness in cable television industry spending.  Overall,  net income
decreased slightly compared to the prior year quarter, primarily due to the loss
of volume at Gilbert Engineering.  The business has reduced its hourly workforce
by approximately 1,175 employees to date.

Sales in the photonic technologies  business increased  approximately 27% in the
first quarter of 2001 to  approximately  $236 million  compared to approximately
$186 million in the prior year quarter. Excluding acquisitions,  sales increased
20% over the prior year  quarter.  Although  sales were up compared to the first
quarter  of 2000,  sales  declined  30% from the  fourth  quarter of 2000 due to
significant  declines in orders from major  customers  caused by the decrease in
capital spending in the  telecommunications  segment.  The business  incurred an
operating loss in the first quarter as a result of excess  capacity and a higher
fixed cost structure compared to the first quarter of last year.

Corning now expects revenues in photonic technologies to be about even with 2000
versus original  expectations that revenues would increase  significantly due to
growth  in  demand  for  photonic  technology  devices.  Corning  is now  making
significant  cost  and  workforce   reductions  to  reflect  the  lower  revenue
expectations.  The  business  reduced its  workforce  through  April 30, 2001 by
approximately  2,500  employees  this year which includes  hourly,  salaried and
temporary positions.

As a  result  of the  sudden  decline  in  orders  for this  business,  photonic
technologies'  inventories  increased  approximately  35%  during  the  quarter.
Management  has taken  action to  significantly  curtail  production  and reduce
inventories over the course of the year.  Although management believes inventory
is currently  realizable,  further  changes in anticipated  customer order rates
and/or changes in customer  specifications  could increase Corning's exposure to
obsolescence in the future.

Corning  has also  significantly  reduced its  capital  expansion  plans in this
business.  Construction of a new  manufacturing  facility in Nashua,  NH will be
completed and then mothballed until increased  demand resumes.  Other previously
announced  capacity  expansions  in the business  will be delayed,  or postponed
until business conditions improve.

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 $14 million in the first quarter of 2001. This business is
also  seeing some  softening  in expected  demand for its  products.  Corning is
investing significant research and development spending in this business.

Sales in the controls and connectors business increased 5% to $60 million in the
first  quarter of 2001  compared to $57 million in the prior year  quarter.  The
modest increase was primarily due to weak customer demand,  particularly in U.S.
markets.  Net income  from these  businesses  improved  slightly,  moving from a
break-even  position in the first quarter of 2000 to moderate  profitability  in
the first quarter of 2001. The business  reduced its workforce by  approximately
525 employees this year in response to current revenue forecasts.

Outlook:  Sales in the  Telecommunications  Segment  are now  expected  to trend
upward by  approximately 9% to 12% primarily based upon the continued demand for
Corning's cabled fiber products. Excluding the impact of acquisitions, sales are
expected to increase 5% to 7%.

Segment net income is expected to decrease 25% to 30% for the year primarily due
to decreased  volumes of amplifiers in photonic  technologies and a lower mix of
premium products in the fiber and cable 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.

First quarter

Sales in the Advanced  Materials  Segment  increased 12% in the first quarter of
2001 to $282  million  compared  to $252  million  in the  prior  year  quarter,
primarily due to strong growth in the semiconductor materials business.  Segment
net income increased 39% in the first quarter of 2001 compared to the prior year
quarter as  improved  operating  performance  more than  offset an  increase  in
research and development  spending,  flat equity earnings and spending to launch
new products in life sciences.

Sales in the environmental  technologies business for first quarter 2001 of $108
million  exceeded first quarter 2000 sales of $103 million by 5%,  primarily due
to continued  strong demand for Corning's  thin wall products,  particularly  in
Asia.  Earnings  in  this  business  for the  first  quarter  of  2001  remained
relatively  flat compared to the prior year  quarter,  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 $70 million in the first quarter of 2001
increased 11% compared to first quarter 2000 sales of $63 million  primarily due
to increased volume of microplates. Earnings in this business were breakeven for
the  2001  quarter  and flat  compared  to first  quarter  2000 as the  business
continues to incur start-up costs for Corning's  microarray  technology products
that  offset  gains  achieved  from  cost  structure  improvements  in the  base
business.

Sales in Corning's other Advanced Materials  businesses increased 21% from first
quarter  2000 to $104  million  in the first  quarter  of 2001  compared  to $86
million in the prior year quarter.  Excluding the impact of the  divestiture  of
Quanterra in the first  quarter of 2000,  sales  improved 30%. This increase was
led by higher sales of high purity fused  silica  products in the  semiconductor
materials  business.  Earnings from these  businesses in first quarter 2001 more
than  tripled  over first  quarter 2000  primarily  due to increased  volume and
despite a decrease in equity earnings from Eurokera, a French based manufacturer
of glass ceramic cooktops.

Outlook:  The  2001  outlook  for  this  operating  segment  remains  relatively
unchanged from that included in Corning's  Form 10-K.  Corning  expects  segment
sales  in  2001  to  increase  8% to  10%  despite  signs  of  softness  in  the
semiconductor  market.  Life science  products,  particularly the new microarray
products,  are also expected to continue to grow. Segment net income is expected
to increase in 2001  reflecting  these sales gains,  aggressive  cost  reduction
initiatives  and the  wind-down of startup costs in  environmental  technologies
offset in part by the continued  investment in research and development spending
on advanced life science products and diesel substrates.

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.

First quarter

Sales in the Information  Display Segment  increased 7% in first quarter 2001 to
$201 million  compared to $188 million in first quarter  2000,  primarily due to
strong growth in the  precision  lens business  offset by flat  performances  in
display technologies and the conventional video components  businesses.  Segment
net income in the first  quarter of 2001 also  remained  flat  compared with the
prior year quarter primarily due to lower equity earnings.

Sales in the conventional video components  business increased 4% to $86 million
in first quarter 2001 compared to $83 million in first quarter 2000. Earnings in
this business for the quarter improved  slightly over first quarter 2000 despite
flat equity  earnings from Samsung Corning Company Ltd., a manufacturer of glass
panels and funnels for televisions and display monitors.

Sales in the display  technologies  business in first  quarter 2001 were flat at
$62  million  compared  to  first  quarter  2000  sales of $61  million.  Volume
increases of 20% were lower than recent quarters due to an inventory  correction
in the  industry  and were  offset by the  impact of the weak yen on  translated
sales.  Earnings in this business for the quarter were down slightly compared to
the same quarter in 2000  primarily due to flat sales and lower equity  earnings
from Samsung Corning Precision,  a Korean manufacturer of liquid crystal display
glass,  due to the  divestment  of Samsung  Corning's  40%  interest  in Samsung
Corning Precision in late 2000.

Sales in the  precision  lens  business  increased  21% to $53  million in first
quarter  2001  compared  to $44  million  in first  quarter  2000 as a result of
continued strong volume growth for projection  televisions  driven by demand for
larger size  televisions in the  entertainment  market sector.  Earnings in this
business for the quarter were  relatively flat in 2001 compared to first quarter
2000,  primarily  due to volume  gains  offset  by  increased  spending  for the
expansion expected to come on-line in the second half of 2001.

Outlook:  Sales in the  Information  Display  Segment  are  expected to increase
approximately 10% to 15% in 2001 and segment net income is also expected to grow
10% to 15%. Both sales and net income outlooks are being negatively  impacted by
the translation rate of the yen which is offsetting expected sales volume gains.






Taxes on Income

Corning's  effective  income tax rate for the first quarter ended March 31, 2001
was 51.1%,  an increase over the 2000 rate of 40.1%.  The increase was primarily
due to the  large  amounts  of  non-tax  deductible  purchased  intangibles  and
goodwill acquired from acquisitions arising in 2000. Excluding the impact of the
amortization  of  purchased  intangibles  and  goodwill,  purchased  IPRD costs,
one-time  acquisition costs and other  nonrecurring  items, the effective income
tax rate for the quarters ended March 31, 2001 and 2000 was approximately 32.5%.

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
$2,436  million  at March 31,  2001.  The  ratio of  current  assets to  current
liabilities  was 2.5 at March 31,  2001  compared  to a current  ratio of 2.4 at
December 31, 2000.  The decrease in working  capital is due primarily to capital
spending, partially offset by a reduction in accounts payable and an increase in
inventories. Corning's long-term debt as a percentage of total capital decreased
slightly from 27% at December 31, 2000 to 26% at March 31, 2001.

Cash Flows

Cash and  short-term  investments  at March 31, 2001 decreased from December 31,
2000 by $645 million.  This decrease is the result of investing activities which
used cash of $683  million  and  financing  activities  which  used cash of $127
million, offset by operating activities which generated cash of $176 million.

Net cash  provided by operating  activities  was $176  million  during the three
months ended March 31, 2001 compared with cash used of $52 million for the prior
year period. This trend is primarily due to increased operating results adjusted
for higher depreciation and amortization of purchased  intangibles and goodwill.
Cash used in working capital was lower in 2001.

Net cash used in investing  activities amounted to $683 million during the three
months  ended March 31,  2001  compared  with  $1,299  million in the prior year
period.  The decrease in cash used was  primarily  related to the high volume of
acquisitions in first quarter 2000 offset in part by higher capital  spending in
2001.

Corning continues to invest  significant cash in capacity  expansions to support
growth in operations. Capital spending for the three months ended March 31, 2001
totaled $576 million compared to $213 million in the prior year period.  Corning
revised its capital  spending plan due to a decrease in forecasted  revenues and
profits for 2001.  Corning  currently  expects its capital spending for the full
year to be in the range of $2 billion.

Net cash used in financing  activities  was $127 million during the three months
ended March 31, 2001 compared with cash provided of $2,387  million in the prior
year  period.  The  substantial  decrease  is due  primarily  to the  timing  of
financing transactions in 2000 that included the equity offering which generated
cash  proceeds of $2.2  billion and the  euro-debt  offering  which  provided an
additional $485 million in 2000.

Dividends paid to common  shareholders for the first quarter totaled $56 million
compared with $50 million in the same period of 2000.

                           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 11 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  $18 million for its  estimated
liability for environmental cleanup and litigation at March 31, 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 the period from December 1996 through  February
1998, Dow Corning filed a plan of reorganization  and two amended plans, each of
which was opposed by creditor representatives. 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). The Joint Plan and
related  disclosure  materials  were  mailed to  claimants  for their  approval.
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.  Corning and Dow
Chemical filed separate  notices of appeal on this issue.  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,
confirming that the Litigation Facility under the Joint Plan is the defendant in
place  of Dow  Corning,  Corning  and Dow  Chemical,  and that  Corning  and Dow
Chemical are not named  defendants for direct claims.  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.  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 will likely
begin to recognize 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 March 31, 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  judgement.  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  District  (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 deferred its ruling in light of the proceedings in
the  Bankruptcy  Court.  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.  Because it believes the deposition will
necessarily impinge on privileged information, Dow Corning filed a petition with
the United  States  Court of Appeals for the Second  Circuit  seeking  immediate
relief.  The Second  Circuit  ruling is expected in the first half 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.  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.

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.  By the first  quarter of 2000,  PCC
incurred adverse  verdicts in five trials  involving 19 claimants.  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. On April 4, 2001, the Bankruptcy Court extended the period for
PCC to  file a plan  of  reorganization  until  July 9,  2001.  The  preliminary
injunction  has been  extended  by court  order to August 23, 2001 to enable the
parties to negotiate a plan of  reorganization  for PCC. Upon  expiration of the
injunction,  PCC, PPG  Industries  and Corning will have 90 days 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,  all of which 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 second quarter of 2001 concerning terms of
PCC's plan of  reorganization,  including whether or not Corning 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. The range of cost for these options (net
of insurance)  cannot be estimated at this time,  although  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.
