To the Corning Incorporated Investment Plan
  Committee and the Participants in
The Corning Incorporated Investment Plan
  for Unionized Employees

In our opinion, the accompanying statements of net assets available for plan
benefits and the related statement of changes in net assets available for plan
benefits present fairly, in all material respects, the net assets available for
benefits of The Corning Incorporated Investment Plan for Unionized Employees
(the "Plan") at December 31, 2001 and 2000, and the changes in net assets
available for benefits for the year ended December 31, 2001, in conformity with
accounting principles generally accepted in the United States of America. 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 audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States of America, which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

PLAN FOR UNIONIZED EMPLOYEES

(DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

1.   DESCRIPTION OF PLAN

     GENERAL

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

     The Plan is a defined contribution profit-sharing-thrift-savings plan
     established in January 1984 and is subject to the Employee Retirement
     Income Security Act of 1974 ("ERISA").

     ADMINISTRATION

     The Plan is administered by the Corning Incorporated Investment Plan
     Committee (the "Committee"), appointed by the Board of Directors of Corning
     Incorporated (the "Company"). The Committee shall administer the Plan in
     accordance with its terms and applicable laws and shall have all necessary
     and appropriate powers to carry out the provisions of the Plan.

     TRUSTEE AND RECORDKEEPER

     The Plan's assets are held by J. P. Morgan Chase Bank, N.A. (the
     "Trustee"), as trustee. The recordkeeper is Mellon HR Solutions.

     ELIGIBILITY

     The Plan covers all union employees of participating unions which contract
     with the Company. 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. At December 31, 2001, the unions at the following
     locations participated in the Plan:

          Blacksburg, Virginia              Greenville, Ohio
          Canton, New York                  Harrodsburg, Kentucky
          Corning, New York                 Oneonta, New York
          Danville, Virginia                State College, Pennsylvania
          Erwin, New York                   Wilmington, North Carolina

     CONTRIBUTIONS - EMPLOYER

     The Company makes matching contributions, out of profits (as defined in the
     Plan), as a percentage of a participant's first 5% of compensation
     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%

THE CORNING INCORPORATED INVESTMENT
PLAN FOR UNIONIZED EMPLOYEES

NOTES TO FINANCIAL STATEMENTS
(DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

1.   DESCRIPTION OF PLAN (CONTINUED)

     CONTRIBUTIONS - EMPLOYER (CONTINUED)

     All matching Company contributions are invested in the Corning Common Stock
     Fund. At December 31, 2001 and 2000, the Corning Common Stock Fund contains
     net assets of approximately $43,500 and $238,300, respectively, that are
     non-participant directed as a result of the accumulation of matching
     contributions made by the Company and the related earnings on those
     contributions. Benefit payments from this non-participant directed fund
     amounted to approximately $4,700 in 2001.

     Effective January 1, 2002, all past and future Company contributions to the
     Plan are fully vested after three years of service. All contributions
     become fully vested upon total and permanent disability, death or
     retirement.

     With respect to all employees eligible to participate in the Plan,
     beginning in January of the year the participant is expected to reach 10
     years of vesting service and irrespective of whether such employee has
     elected to contribute to the Plan, the Company contributes weekly or
     monthly (based on employee's pay frequency) a supplemental contribution to
     the Corning Common Stock Fund an amount equal to 1.175% of such employee's
     compensation.

     CONTRIBUTIONS - PARTICIPANTS

     Generally, participants may contribute up to 15% of their base salary on a
     before tax basis, after tax basis or any combination of the two, to the
     Plan. Highly compensated participants are limited to contribute 1% to 9% of
     their base salary before tax, and 1% to 6% of their base salary after tax,
     not to exceed 15% in total. The maximum amount a participant can contribute
     to the Plan on a before tax basis is $10,500 per year as adjusted by the
     Internal Revenue Service for cost of living increases.

     Participants may also elect to have their contributions invested in the
     Corning Common Stock Fund on a before or after tax basis. The Company will
     make a premium matching contribution for the account of each participant in
     an amount equal to 15% of such participant's contributions to the Corning
     Common Stock Fund.

     FUND TRANSFERS

     Participants are allowed to transfer their accumulated contributions
     between funds. There are certain restrictions, however, on transfers
     involving the Corning Common Stock Fund. First, only participants age 55 or
     over are allowed to transfer Company contributions in the Corning Common
     Stock Fund into any of the other investment funds. Second, employee
     contributions into the Corning Common Stock Fund are available for transfer
     out after the funds have been in the Plan for five years. The earnings on
     employee contributions to the Corning Common Stock Fund are unrestricted
     and eligible for transfer at any time.

PLAN FOR UNIONIZED EMPLOYEES

NOTES TO FINANCIAL STATEMENTS
(DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

1.   DESCRIPTION OF PLAN (CONTINUED)

     FUND TRANSFERS (CONTINUED)

     Effective January 1, 2002, the following Plan amendments apply to employees
     at the Erwin Park Photonics Plan in Erwin, New York who are covered by a
     collective bargaining agreement:

          - Employees age 55 or over may transfer Company contributions back
             into the Corning Common Stock Fund at any time, and

          - Employee contributions in the Corning Common Stock Fund are no
             longer subject to the five-year restriction described above.

     No transfers may be made into the Corning Preferred Stock Fund. Transfers
     from the Corning Preferred Stock Fund can only be made to the Corning
     Common Stock Fund.

     DISTRIBUTIONS TO PARTICIPANTS

     Distributions are made upon retirement (i.e., at least age 55 with five
     years of service) or in the event of a participant's total and permanent
     disability, death 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. As of December 31, 2001 and 2000, there
     were 3,319 and 2,949, respectively, terminated and retired participants in
     the Master Trust with a total vested value of $379,097 and $573,732,
     respectively.

     PARTICIPANT LOANS

     Participants are eligible to obtain loans from the Plan. Loans are limited
     to one loan with a repayment term not to exceed 4.5 years, except for
     primary residence loans in which the term may not exceed 10 years. The
     maximum amount of any loan is the lesser of one-half of the vested account
     balance, or $50,000 (with a $1,000 minimum). The interest rate on a loan is
     the prime rate plus 1% on the last business day of the month before the
     request for a loan.

     ADMINISTRATIVE FEES

     Participants in the Plan are charged an account fee which is deducted from
     each participant's account. Also, participants in the Plan are charged a
     loan fee which decreases the participant's 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 generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of net assets available for
     plan benefits and changes therein. Due to the inherent uncertainty involved
     in making estimates actual results reported in future periods may be based
     on amounts that 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, 2001 and 2000, the Plan's percentage interest in the net assets of the
     Master Trust was approximately 18% and 23%, respectively.

     VALUATION OF MASTER TRUST INVESTMENTS

     Master Trust investments in mutual and collective trust funds are recorded
     at fair market 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 issuer
     or otherwise. At December 31, 2001, the average crediting interest rate was
     approximately 7%. The Company's Preferred Sock is valued at 14.37 times the
     market value of Corning Common Stock (Note 3). Participant loans receivable
     are valued at cost plus accrued interest which approximates fair value.

     RISK 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 of such investments
     reported in the Plan's financial statements.

4.   INVESTMENT IN THE CORNING PREFERRED STOCK FUND

     Effective September 6, 1989, the Plan was amended to reflect the creation
     of a Series B Convertible Preferred Stock, $100 par value (the "Preferred
     Stock") to be offered to Plan participants. The participants were given the
     opportunity to designate a portion of their contributions to be invested in
     the Preferred Stock.

4.   INVESTMENT IN THE CORNING PREFERRED STOCK FUND (CONTINUED)

     Distributions paid and transfers from the Corning Preferred Stock Fund must
     first be converted to the Company's Common Stock in whole shares only. The
     conversion rate is 14.37 shares of Common Stock for each share of Preferred
     Stock converted, with a minimum value of $100 (par value). Effective
     October 3, 2000, a 3-for-1 stock split increased the conversion rate from
     4.79 to 14.37. The $100 floor applies to all transactions involving
     Preferred Stock unless the participant is under age 55 and the transaction
     is a non-hardship withdrawal.

     Dividends on the Preferred Stock are declared quarterly and are payable as
     of the end of each calendar quarter. The dividend rate is equal to $2 per
     share of preferred stock. Dividends paid on shares of Preferred Stock are
     reinvested in the Stable Value Fund.

5.   INVESTMENT IN THE CORNING COMMON STOCK FUND

     During 2001, the Master Trust purchased 4,450,529 shares of the Company's
     Common Stock at an aggregate cost of $82,787 and sold 755,863 shares for
     proceeds of $18,408 resulting in realized gains of $8,571. The Master Trust
     distributed 468,902 shares of Common Stock having a market value of $10,194
     (cost of $6,647). The participants of the plans converted preferred shares
     or contributed cash for the purchase of 1,724,619 shares of Common Stock
     having a market value of $26,318 to the Master Trust. At December 31, 2001
     and 2000, the Master Trust held 26,816,849 and 21,884,466 shares of Common
     Stock of the Company, respectively, of which the Plan had specific
     ownership of 7,451,666 and 6,636,487 shares, respectively. The activity in
     the Corning Common Stock Fund prior to October 3, 2000 was adjusted for the
     3-for-1 stock split effective October 3, 2000.

6.   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.

7.   TAX STATUS

     The Plan received a favorable determination letter dated March 11, 1996
     from the Internal Revenue Service indicating that it meets the requirements
     of Section 401(a) of the Internal Revenue Code and qualifies as a
     tax-exempt organization. The Plan has been amended since receiving the
     determination letter. However, the plan administrator believes that the
     Plan is designed and is currently being operated in compliance with the
     applicable provisions of the IRC.
