             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
             -------------------------------------------------------


To the Corning Incorporated Benefits Plan Committee and
the Participants of the Corning Incorporated Investment Plan

We have audited the accompanying  statement of net assets available for benefits
of Corning Incorporated  Investment Plan (the Plan) as of December 31, 2004, and
the related  statement of changes in net assets  available  for benefits for the
year then ended. These financial statements are the responsibility of the Plan's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements based on our audit.

We conducted our audit in accordance  with the auditing  standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain  reasonable  assurance about whether the
financial  statements  are free of  material  misstatement.  An  audit  includes
examining,  on a test basis,  evidence supporting the amounts and disclosures in
the  financial  statements.  An audit also  includes  assessing  the  accounting
principles  used  and  significant  estimates  made  by  management,  as well as
evaluating the overall  financial  statement  presentation.  We believe that our
audit provides a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all  material  respects,  the net  assets  available  for  benefits  of  Corning
Incorporated  Investment  Plan as of December 31,  2004,  and the changes in net
assets  available for benefits for the year then ended,  in conformity with U.S.
generally accepted accounting principles.

Our audit was made for the purpose of forming an opinion on the basic  financial
statements taken as a whole. The supplemental schedule of assets (held at end of
year) as of December  31,  2004,  is  presented  for the  purpose of  additional
analysis and is not a required part of the basic  financial  statements,  but is
supplementary  information  required by the United  States  Department  of Labor
Rules and Regulations for Reporting and Disclosure under the Employee Retirement
Income Security Act of 1974. This supplemental schedule is the responsibility of
the Plan's  management.  The  supplemental  schedule  has been  subjected to the
auditing procedures applied in the audit of the basic financial  statements and,
in our opinion,  is fairly  stated in all  material  respects in relation to the
basic financial statements taken as a whole.

Respectfully Submitted,

assets available for benefits of the Corning  Incorporated  Investment Plan (the

accepted  in the United  States of  America.  This  financial  statement  is the

opinion on this financial  statement  based on our audit. We conducted our audit
of this  statement  in  accordance  with the  standards  of the  Public  Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the statement
of net assets is free of material misstatement.  An audit includes examining, on
a test basis,  evidence  supporting the amounts and disclosures in the statement
of  net  assets,  assessing  the  accounting  principles  used  and  significant
estimates made by management, and evaluating the overall statement of net assets
presentation.  We believe that our audit of the statement of net assets provides
a reasonable basis for our opinion.

Corning Incorporated Investment Plan
Notes to Financial Statements
December 31, 2004 and 2003
--------------------------------------------------------------------------------

(in thousands of dollars)

1.   Description of Plan

     General
     The following brief description of the Corning Incorporated Investment Plan
     (the  "Plan")  is  provided   for  general   information   purposes   only.
     Participants should refer to the Plan document and summary plan description
     for a more complete description of the Plan's provisions.

     The Plan is a  defined  contribution  profit-sharing  plan  established  in
     January 1967  and is subject to the  provisions of the Employee  Retirement
     Income Security Act of 1974, as amended ("ERISA").

     Effective  February 2, 2004,  the net assets of the Corning  Cable  Systems
     Retirement  Plan  ("CCSRP") and the Corning Cable Systems  Investment  Plan
     ("CCSIP")  merged  into the Plan.  Both CCSRP and CCSIP were  sponsored  by
     Corning Incorporated (the "Company").

     Administration
     The Plan is administered  by the Corning  Incorporated  Benefits  Committee
     (the  "Committee"),  which is  appointed  by the Board of  Directors of the
     Company.  The Committee  administers  the Plan in accordance with its terms
     and applicable laws and has all necessary and  appropriate  powers to carry
     out the provisions of the Plan.

     Trustee and Recordkeeper
     The Plan's  assets are held by  JPMorgan  Chase  Bank (the  "Trustee"),  as
     trustee.  The recordkeeper is Affiliated Computer Services,  Inc. (formerly
     known as Mellon Human Resource and Investor Solutions).

     Eligibility
     The Plan covers all employees of the Company and participating subsidiaries
     who are not members of a union.  An employee is eligible for  participation
     in the Plan upon reaching the age of 18 and completing one year of eligible
     service. Notwithstanding the foregoing, an employee who has attained age 18
     and is  scheduled  on a normal basis to work at least 16 hours a week shall
     be immediately eligible.

     Participant Accounts
     Each participant's account is credited with the participant's  contribution
     and allocations of (a) the  Company's  contribution and (b) Plan  earnings,
     and charged for administrative expenses.  Trustee and investment management
     fees are deducted from the earnings credited to participant's  accounts.  A
     flat  monthly  fee is charged to each  participant's  account to  subsidize
     administrative  expenses  of  the  Plan  and  is  determined  by  the  plan
     administrator. Administrative fees, such as investment management fees, are
     pro-rated  among the  investment  funds as of the last business day of each
     month.  The benefit to which a participant  is entitled is the benefit that
     can be provided from the participant's vested balance.

     Vesting
     Participants  are vested  immediately  in their  contributions  plus actual
     earnings thereon.  Company contributions to the Plan are fully vested after
     three years of service. All Company  contributions become fully vested upon
     total and permanent disability, early retirement or normal retirement.

     Contributions - Employer
     Depending  upon  date  of  hire  or  employee  election,  Company  matching
     contributions will be determined under the following provisions:

          1)   Employees  hired on or after July 1,  2000 (and  employees  hired
               before   July 1,   2000   who  so   elected)   receive   matching
               contributions  that  equal 100% of the first 2% of  eligible  pay
               contributed  and 50% of the next 4% of eligible pay  contributed,
               up to 6% of eligible pay.

          2)   Certain  employees  hired before  July 1,  2000  receive  Company
               matching  contributions as a percentage of a participant's  first
               5% of eligible pay  contributed  according to years of service as
               of December 31 of the prior year as follows:

               Less than 19 years of service                                50%

               19 but less than 24 years of service                         75%

               24 or more years of service                                 100%

          3)   In 2003,  the Company  reduced its  contributions  to the Plan by
               2.5% of eligible  pay.  This applied to all  participants  except
               union-free hourly participants.  If a participant was entitled to
               receive both matching and the supplemental contribution, the 2.5%
               reduction was made proportionally  between the two contributions.
               Effective  January 1,  2004, the plan  provision  adopted in 2003
               prescribing a 2.5% of pay reduction in Company  contributions was
               eliminated.

     With  respect to all  employees  eligible  to  participate  in the Plan and
     covered by the service-based match described above, beginning in January of
     the year the  participant is expected to reach ten years of vesting service
     and  irrespective of whether such employee has elected to contribute to the
     Plan, the Company  contributes  weekly,  bi-weekly or monthly (based on the
     employee's pay frequency) a supplemental contribution to the Corning Common
     Stock Fund equal to 1.175% of such employee's compensation. Employees hired
     on or after July 1, 2000 do not receive the supplemental contribution.

     All Company  contributions  are invested in the Corning  Common Stock Fund.
     Effective January 1,  2003, participants may transfer Company contributions
     and associated earnings into any other plan fund.

(in thousands of dollars)


     Forfeiture  credits of $603 were used to reduce employer  contributions  in
     2004.  As of  December 31,  2004,  the amount of  forfeitures  available to
     reduce  future  employer  contributions  to this  plan and the  other  plan
     sponsored  by  the  Company  with  a  specific   interest  in  the  Corning
     Incorporated Master Investment Trust is $1,477.

     Contributions - Participants
     Generally,  participants  may contribute up to 75% of their eligible salary
     on a before-tax  basis,  after-tax  basis or any combination of the two, to
     the Plan. Prior to October 1,  2003,  contributions  of highly  compensated
     participants were limited to 1% to 11% of their base salary before tax, and
     1% to 4% of their base salary after tax, not to exceed 15% in total.  These
     limits were eliminated July 1, 2004.  Effective  January 1,  2004, the Plan
     was amended to limit  employees'  elections to invest future  contributions
     into the Corning  Common  Stock  Fund.  The  maximum  investment  direction
     election under this new restriction is 20%.

     The maximum amount a participant can contribute to the Plan on a before-tax
     basis is $13 per year in 2004 as  adjusted  by the  Internal  Revenue  Code
     ("IRC").  The Plan was amended effective  July 1,  2004 to permit employees
     who will have  attained age 50 or older  during a given year to  contribute
     additional  before-tax  amounts up to the  prescribed  IRC  limitation  for
     "catch-up contributions."

     Participants  may also elect to have their  contributions  invested  in the
     Corning Common Stock Fund on a before or after-tax basis.

     Fund Transfers
     Participants  are  allowed  to  transfer  their  accumulated  contributions
     between funds. Effective January 1,  2004, the Plan was amended to prohibit
     the  transfer  of amounts  invested in other Plan  investment  funds to the
     Corning Common Stock Fund.

     Payment of Benefits
     Benefit payments are made upon retirement  (i.e., at least age 55 with five
     years of  service),  or in the event of a  participant's  death,  total and
     permanent  disability  or  other  termination  of  employment.   A  retired
     participant can elect to receive distributions in a lump sum, installments,
     or  intermittent  withdrawals.  The Plan also provides for  withdrawals  by
     participants prior to termination.

     Participant Loans
     Participants  are eligible to obtain loans from the Plan. Loans are limited
     to one loan per participant with a repayment term not to exceed  4.5 years,
     except  for  primary  residence  loans in which the term may not exceed ten
     years.  The  maximum  amount of any loan is the lesser of  one-half  of the
     vested account  balance or $50 (with a $1 minimum).  The interest rate on a
     loan is established by the Committee. Also, participants are charged a loan
     fee which reduces the loan proceeds.

2.   Summary of Significant Accounting Policies

     Basis of Presentation
     The accompanying  financial statements are prepared on the accrual basis of
     accounting.

     Use of Estimates
     The  preparation  of financial  statements  in conformity  with  accounting
     principles  generally  accepted  in the United  States of America  requires
     management  to make  estimates  and  assumptions  that affect the  reported
     amounts of net assets  available for benefits and changes  therein.  Due to
     the  inherent  uncertainty  involved in making  estimates,  actual  results
     reported in future periods could differ from those estimates.

     Basis of Allocation from the Corning  Incorporated  Master Investment Trust
     The  Plan  has a  specific  interest  in the  Corning  Incorporated  Master
     Investment  Trust (the "Master  Trust") in which another plan  sponsored by
     the Company also  participates.  The Plan's specific interest in the Master
     Trust is  credited  or charged for  contributions,  transfers,  and benefit
     payments  relating  to its  participants.  Realized  gains and  losses  and
     changes in net unrealized  appreciation  or  depreciation  on  investments,
     income from investments and expenses are allocated to the Plan based on the
     Plan's  specific  interest  in the  net  assets  of the  Master  Trust.  At
     December 31,  2004 and 2003,  the  Plan's  percentage  interest  in the net
     assets of the Master Trust was approximately 84% and 81%, respectively.

     Valuation of Master Trust Investments
     Master Trust  investments in mutual and collective trust funds are recorded
     at fair value based upon the net asset value  announced  by the fund on the
     last business day of the year.  Investment contracts are valued at contract
     value, representing  contributions made plus interest at the contract rate,
     less funds  withdrawn and  administrative  expenses.  There are no reserves
     against  contract  values  for  credit  risk  of the  contract  issuers  or
     otherwise.  Investment contracts are fully benefit-responsive.  The Company
     does not expect any  employer  initiated  events  that may cause  premature
     liquidation of a contract at market value. At  December 31,  2004 and 2003,
     investment  contracts  held by the Master Trust were $407,345 and $421,447,
     respectively,  at contract  value.  The contract  values  approximate  fair
     value. The average yield and crediting interest rates were approximately 6%
     for 2004 and  2003.  The  crediting  interest  rates are based on a formula
     agreed upon with the issuers.

     Interest  is accrued  by the Master  Trust as  earned,  and  dividends  are
     recorded on the ex-dividend date.

     Purchases  and sales of  securities  are  recorded by the Master Trust on a
     trade-date basis.  Realized gains and losses for security  transactions are
     reported  using the  average  cost  method.  Unrealized  gains  and  losses
     represent the difference between the cost and fair value of securities.

     Valuation of Participant Loans
     Participant   loans  are  valued  at  cost  plus  accrued   interest  which
     approximates fair value.

     Payment of Benefits
     Benefits are recorded when paid.

     Risks and Uncertainties
     The Plan's  investment  securities  are exposed to various  risks,  such as
     changes  in  interest  rates and market  returns.  Due to the level of risk
     associated with certain investments and the level of uncertainty related to
     changes  in the  value of  these  investments,  it is at  least  reasonably
     possible  that  changes in  valuations  in the near term  would  materially
     affect  participants'  account  balances  and the  amounts  reported in the
     Plan's financial statements.

4.   Plan Termination

     Although  it has not  expressed  any intent to do so, the  Company  has the
     right to terminate  the Plan  subject to the  provisions  of ERISA.  In the
     event of Plan termination,  all amounts credited to participants'  accounts
     will  become  100%  vested  and  will be  distributed  to  participants  in
     accordance with Plan provisions.

5.   Tax Status

     The Plan received a favorable  determination letter dated November 5,  2003
     from the Internal Revenue Service indicating that it meets the requirements
     of  Section  401(a) and  501(a) of the IRC and has  qualified  status as an
     employee  retirement  plan.  The Plan has been amended since  receiving the
     determination  letter.  However,  the  plan  administrator  and the  Plan's
     benefits  counsel  believe that the Plan is designed and is currently being
     operated in compliance with the applicable provisions of the IRC.

6.   Subsequent Events

     Effective January 1,  2005,  participants of the Corning Oak Holding,  Inc.
     Section 401(k)  Savings Plan (the Oak Plan) became  eligible to participate
     in the Plan. On  February 2,  2005,  the assets of the Oak Plan were merged
     into the Plan.

     Effective  April 1, 2005, the Fidelity Low Priced Stock Fund was eliminated
     as an investment option for participants. In addition, the Fidelity Mid-cap
     Stock Fund was replaced with the Vanguard Mid-cap Index Fund.

     Effective March 28, 2005, the mandatory lump-sum distribution threshold was
     lowered to $1 to comply with the  restrictions set forth under The Economic
     Growth and Tax Relief Reconciliation Act of 2001 ("EGTRRA").
