                    INTRODUCTORY STATEMENT TO AMENDMENT NO. 2

     This  Amendment No. 2 to Tender Offer  Statement on Schedule TO dated as of
June 5, 2003,  relates to an offer by Corning  Incorporated  ("Corning"),  a New
York corporation,  to purchase for cash up to $834,000,000  aggregate  principal
amount at maturity of its Zero Coupon  Convertible  Debentures  due  November 8,
2015 (the  "Notes") at a purchase  price of not greater  than $750 nor less than
$725 per $1,000 principal amount at maturity of the Notes.  This amount includes
2% of the outstanding  principal  amount at maturity of the Notes in addition to
the principal amount at maturity originally sought in the offer.  Reference to a
Note in the singular refers to a Note  representing  $1,000  principal amount at
maturity.

     This  Amendment  No. 2 to Tender  Offer  Statement  on Schedule TO is being
filed by Corning and amends and  supplements  certain  provisions  of  Corning's
Tender  Offer  Statement on Schedule TO filed with the  Securities  and Exchange
Commission  (the "SEC") on May 7, 2003,  and amended on May 20, 2003 (as amended
and supplemented, the "Schedule TO") and Corning's offer for the Notes set forth
in the Offer to Purchase for Cash Up to $800,000,000  Aggregate Principal Amount
at Maturity of its Outstanding Zero Coupon  Convertible  Debentures Due November
8, 2015  (CUSIP No.  219350 AJ 4) (as amended  and  supplemented,  the "Offer to
Purchase"),  and the related Letter of  Transmittal,  as amended (as amended and
supplemented,  the "Letter of  Transmittal")  which,  together with the Offer to
Purchase, constitute the "Offer") and both of which are filed as Exhibits to the
Schedule TO with the SEC. The Offer expired at 12:00 midnight,  Eastern Time, on
June 4, 2003. The Schedule TO, as amended and supplemented  hereby,  is intended
to satisfy the reporting  requirements of Rule 13e-4(c)(2)  under the Securities
Exchange Act of 1934, as amended.

     Capitalized  terms used in this amendment and not otherwise  defined herein
have the meanings given to them in the Offer to Purchase and the Schedule TO.

Item 1. Summary Term Sheet

     The Summary Term Sheet set forth in the Offer to Purchase is hereby amended
to  substitute  as the offered  amount to be  purchased  $834,000,000  aggregate
principal amount at maturity for $800,000,000 in each place where it appears.

     Each other place in the Offer to Purchase or Letter of  Transmittal  or any
other  document  which is an Exhibit to Corning's  Schedule  TO, as amended,  is
hereby amended to substitute as the amount offered to be purchased, $834,000,000
aggregate principal amount at maturity for $800,000,000.

Item 4. Terms of the Transaction

     Item 4 of the Schedule TO is hereby amended and  supplemented by adding the
following language:

     The Offer expired at 12:00  midnight,  Eastern Time, on Wednesday,  June 4,
2003.  Approximately $848 million aggregate  principal amount at maturity of the
Notes were validly tendered and not withdrawn, at or below the purchase price in
the Offer,  including  approximately $35 million  aggregate  principal amount at
maturity  tendered by notice of  guaranteed  delivery.  Corning  will accept for
purchase  up to $834  million  aggregate  principal  amount at  maturity  of the
validly  tendered  and not  withdrawn  Notes at a purchase  price of $747.50 per
$1,000 principal amount at maturity of Notes,  subject to satisfactory  delivery
of Notes  tendered by notice of guaranteed  delivery.  Because more of the Notes
were validly tendered at or below the purchase price and not withdrawn, than are
being  accepted for  payment,  Notes  validly  tendered at or below the purchase
price will be purchased on a pro rata basis.  Corning expects that the proration
factor will be approximately  98%. The proration factor and the principal amount
at  maturity  of  Notes to be  purchased  are  preliminary  and are  subject  to
verification  by the  Depositary.  The final  proration  factor  and the  actual
principal amount at maturity of Notes to be purchased will be announced promptly
following  completion  of the  verification  process.  Corning  expects  to make
payment to the Depositary  for the Notes  accepted for purchase,  and return all
other  Notes  tendered  but not  accepted,  promptly  after  completion  of such
verification  process.  Corning expects final  verification  and payment for the
Notes  accepted for purchase to occur by June 12, 2003.  On June 5, 2003 Corning
issued a press release  announcing the preliminary  results of the Offer. A copy
of this press  release is filed as Exhibit  (a)(5)(C)  to the Schedule TO and is
incorporated herein by reference.

              Corning Announces Preliminary Results of Tender Offer


CORNING,  N.Y.-- Corning Incorporated (NYSE:GLW) today announced the preliminary
results  of its  modified  Dutch  auction  tender  offer for up to $800  million
aggregate   principal   amount  at  maturity  of  its  outstanding  zero  coupon
convertible debentures.  The offer expired at midnight, Eastern Time, on June 4,
2003.

Based on  preliminary  information,  Corning will accept for purchase up to $834
million  aggregate  principal amount at maturity of debentures  validly tendered
and not withdrawn at a purchase price of $747.50 per $1,000 of principal  amount
at maturity,  subject to satisfactory  delivery of debentures tendered by notice
of guaranteed  delivery.  The purchase price applies to all debentures  accepted
for  payment   pursuant  to  the  offer.   Based  on  preliminary   information,
approximately  $848  million  principal  amount at maturity of  debentures  were
validly  tendered at or below the purchase  price and not  withdrawn,  including
approximately  $35  million  of  debentures  tendered  by notice  of  guaranteed
delivery.

Because more of the  debentures  were validly  tendered at or below the purchase
price and not withdrawn, than are being accepted for payment, Corning expects to
apply a proration  factor of  approximately  98% to all debentures  accepted for
payment in the offer.  The final proration  factor is subject to verification by
the depositary.

Payment for the  debentures  accepted  for purchase is expected to occur by June
12, 2003, when we announce final results. Corning will use up to $623 million in
cash to complete  the tender.  All  debentures  not accepted for payment will be
promptly returned to holders.
