SUBJECT:      Corning Incorporated and Corning Delaware, L.P. Combined
Registration         Statement on Form S-3

Gentlemen:

              On behalf of Corning Incorporated ("Corning") and Corning 
Delaware, L.P. ("Corning Delaware"), we are hereby filing under the 
Securities Exchange Act of 1933, as amended, Corning's and Corning 
Delaware's Combined Registration Statement on Form S-3 (the "Registration 
Statement") related to (i) the issuance and sale of Corning Delaware's 
Convertible Monthly Income Preferred Securities (the "Preferred Securities"), 
(ii) the shares of Corning Series C Convertible Preferred Stock, $ 100
par value, issuable upon certain events in exchange for the Preferred 
Securities, as set forth in the Registration Statement, (iii) the shares 
of Corning Common Stock, $.50 par value, issuable upon conversion of the 
Preferred Securities and (iv) the Guarantee of the Preferred Securities 
by Corning.  The filing fee of $ 109,053 has been sent by wire transfer 
by Corning to the Commission's lockbox facility at the Mellon Bank in 
Pittsburgh, Pennsylvania.

              Please note that while not required to be incorporated by 
reference pursuant to Form S-3 (Item 12(a)(2)), certain historical 
financial statements of Damon Corporation, which was acquired by Corning 
in 1993, are incorporated by reference in the Registration Statement 
through Corning's Current Reports on Form 8-K dated August 4, 1993 and 
August 13, 1993 in the interest of providing prospective investors with 
full disclosure.

              In addition, please note that we have elected to use Form S-3, 
even though the Preferred Securities of Corning Delaware are convertible, 
on the basis that such convertible securities are convertible into the 
securities of Corning, the guarantor, and not into other securities of 
Corning Delaware or securities of any other entity.

              




              





       If you should have any questions or comments concerning this filing, 
please call Cornelius J. Dwyer, Jr. at (212) 848-7019 or the undersigned at 
(212) 848-8983 at Shearman & Sterling or Robert W. Reeder at (212) 558-3755

                             CORNING INCORPORATED 

The    ,   ,000    % Convertible Monthly Income Preferred Securities (the 
"Preferred Securities") are being issued by Corning Delaware, L.P. ("Corning 
Delaware"), a Delaware limited partnership. All of the partnership interests 
in Corning Delaware, other than the limited partnership interests represented 
by the Preferred Securities, are owned by Corning Incorporated, a New York 
corporation ("Corning" or the "Company"), which is the general partner in 
Corning Delaware. The Preferred Securities will have a preference over all 
other partnership interests of Corning Delaware with respect to cash 
distributions and amounts payable on liquidation. 

Holders of the Preferred Securities will be entitled to receive cumulative 
cash distributions from Corning Delaware, at an annual rate of    % of the 
liquidation preference of $50 per Preferred Security, accruing from the date 
of original issuance and payable monthly in arrears on the last day of each 
calendar month of each year, commencing          , 1994 ("dividends"). See 
"Description of Securities Offered--Preferred Securities--Dividends." 
                                                      (continued on next page) 

 See "Investment Considerations" for a discussion of certain factors to be 
considered in connection with an investment in the Preferred Securities, 
including circumstances under which interest payments on the Subordinated 
Debentures (as defined) may be deferred for up to 60 months. 

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES 
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS 
THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES 
COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. 
ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE. 



                                                  Initial Public    Underwriting           Proceeds to

(1) Corning Delaware and Corning have agreed to indemnify the Underwriters 
against certain liabilities, including liabilities under the Securities Act 
of 1933, as amended. See "Underwriting." 
(2) In view of the fact that the proceeds of the sale of the Preferred 
Securities will ultimately be used by Corning Delaware to purchase 
convertible subordinated debentures of Corning, the Underwriting Agreement 
provides that Corning will pay to the Underwriters, as compensation 
("Underwriters' Compensation"), $      per Preferred Security (or $    in the 
aggregate). See "Underwriting." 
(3) Expenses of the offering which are payable by Corning are estimated to be 
$    . 
(4) Corning Delaware and Corning have granted the Underwriters an option for 
30 days to purchase up to an additional       Preferred Securities at the 
initial public offering price per share, less the Underwriters' Compensation, 
solely to cover over-allotments. If such option is exercised in full, the 
total initial public offering price, underwriting commission and proceeds to 
Corning Delaware will be $, $and $, respectively. See "Underwriting." 

The Preferred Securities offered hereby are offered severally by the 
Underwriters, as specified herein, subject to receipt and acceptance by them 
and subject to their right to reject any order in whole or in part. It is 
expected that delivery of the Preferred Securities will be made only in 
book-entry form through the facilities of The Depository Trust Company on or 
about           , 1994.

The date of this Prospectus is       , 1994. 

(continued from previous page) 

In the event of the liquidation of Corning Delaware, holders of Preferred 
Securities will be entitled to receive for each Preferred Security a 
liquidation preference of $50 plus accumulated and unpaid dividends to the 
date of payment, subject to certain limitations. See "Description of 
Securities Offered--Preferred Securities--Liquidation Rights." 

   
Each Preferred Security is convertible through Corning Delaware at the option 
of the holder, at any time, unless previously redeemed or exchanged, into 
shares of Corning Common Stock, par value $.50 per share ("Corning Common 
Stock"), at the rate of   shares of Corning Common Stock for each Preferred 
Security (equivalent to a conversion price of $   per share of Corning Common 
Stock), subject to adjustment in certain circumstances. See "Description of 
Securities Offered--Preferred Securities--Conversion Rights." The last 
reported sale price of Corning Common Stock, which is listed under the symbol 
"GLW" on the New York Stock Exchange, on May 25, 1994 was $33.750 per share. 
The Preferred Securities are also subject to exchange, in whole but not in 
part, into shares of Series C Convertible Preferred Stock, par value $100 per 
share ("Corning Series C Preferred Stock"), upon a vote of the holders of a 
majority of the aggregate liquidation preference of all outstanding Preferred 
Securities upon the failure of holders of Preferred Securities to receive 
dividends in full for 15 consecutive months and/or upon the occurrence of a 
Tax Event (as defined herein). The Corning Series C Preferred Stock will have 
dividend, conversion and optional redemption features substantially identical 
to those of the Preferred Securities but will not be subject to mandatory 
redemption. See "Description of Securities Offered--Preferred 
Securities--Optional Exchange for Corning Series C Preferred Stock" and 
"--Description of Corning Series C Preferred Stock." 
    

The Preferred Securities are redeemable, at the option of Corning Delaware, 
in whole or in part, on or after June   , 1998, at the redemption prices set 
forth herein, together with accumulated and unpaid dividends to the date 
fixed for redemption. The Preferred Securities are subject to mandatory 
redemption on the 30th anniversary of the date of original issuance. See 
"Description of Securities Offered--Preferred Securities--Optional 
Redemption" and "--Mandatory Redemption." 

Corning will unconditionally guarantee, to the extent set forth herein, the 
payment of dividends by Corning Delaware on the Preferred Securities (if and 
to the extent declared from funds legally available therefor), the redemption 
price (including all accumulated and unpaid dividends) payable with respect 
to the Preferred Securities and payments on liquidation with respect to the 
Preferred Securities (to the extent of the assets of Corning Delaware 
available for distribution to holders of the Preferred Securities). The 
guarantee will be unsecured and will be subordinate to all liabilities of 
Corning and will rank pari passu with the most senior preferred or preference 
stock now or hereafter issued by Corning. The proceeds from the offering of 
the Preferred Securities will be invested by Corning Delaware in convertible 
subordinated debentures of Corning (the "Subordinated Debentures") having the 
terms described herein. Interest payment periods on the Subordinated 
Debentures are monthly but may be extended by Corning for up to 60 months, in 
which event Corning Delaware would be unable to make monthly dividend 
payments on the Preferred Securities. The failure of holders to receive 
dividends in full for 15 consecutive months would trigger the right of the 
holders of the Preferred Securities to cause Corning Delaware to exchange the 
Subordinated Debentures for shares of Corning Series C Preferred Stock and 
distribute such shares to the holders of the Preferred Securities. See 
"Description of Securities Offered--Description of the Guarantee" and 
"--Description of the Subordinated Debentures" for a description of the 
various contractual obligations of Corning relating to the Preferred 
Securities. 

Application will be made to list the Preferred Securities on the New York 
Stock Exchange under the symbol "GLW pfM." 

The Preferred Securities will be represented by a global certificate or 
certificates registered in the name of The Depository Trust Company ("DTC") 
or its nominee. Beneficial interests in the Preferred Securities will be 
shown on, and transfers thereof will be effected only through, records 
maintained by the participants of DTC. Except as described herein, Preferred 
Securities in certificated form will not be issued in exchange for the global 
certificates. See "Description of Securities Offered--Preferred 
Securities--Book-Entry-Only Issuance--The Depository Trust Company." 

*An application has been filed by Goldman, Sachs & Co. with the United States 
Patent and Trademark Office for the registration of the MIPS servicemark.

information and consolidated financial statements (including the notes

Unless otherwise specified, references herein to the "Company" or "Corning"

                               CORNING DELAWARE 

Corning Delaware is a special purpose limited partnership formed under the 
laws of the State of Delaware. All of its partnership interests (other than 
the Preferred Securities) are currently and will be beneficially owned 
directly or indirectly by Corning. Corning is the sole general partner (the 
"General Partner") in Corning Delaware. 

                                 THE COMPANY 

Corning traces its origins to a glass business established by the Houghton 
family in 1851. The present corporation was incorporated in the State of New 
York in December 1936, and its name was changed from Corning Glass Works to 
Corning Incorporated on April 28, 1989. 

Corning is an international corporation competing in four broadly-based 
business segments: Specialty Materials, Communications, Laboratory Services 
and Consumer Products. Corning is engaged principally in the manufacture and 
sale of products made from specialty glasses and related inorganic materials 
having special properties of chemical stability, electrical resistance, heat 
resistance, light transmission and mechanical strength. Corning and its 
subsidiaries annually produce some 60,000 different products at 44 plants in 
eight countries. In addition, Corning, through subsidiaries and affiliates, 
engages in laboratory services businesses, including life and environmental 
sciences and clinical-laboratory testing, at 62 facilities in ten countries. 

Corning has followed and will continue to follow a consistent strategy for 
its businesses: 

  --to provide quality products and services to the four broad market 
segments in which it chooses to compete, 

  --to be a market leader in each of its businesses, and 

  --to fully utilize the talents and capabilities of all its employees. 

Corning utilizes various strategies and tactics appropriate to each business 
and its specific markets. However, all strategies incorporate certain key 
elements. 

In addition to the restructuring programs already under way, Corning is 
currently engaged in a comprehensive review of its business and cost 
structure. Corning expects this review to be substantially completed by the 
end of 1994. 

Technology has been at the core of Corning's historical success. Corning's 
investment in research and development has been significant at $131 million 
in 1991; $151 million in 1992; and $173 million in 1993. Research and 
development spending has enabled Corning to remain at the forefront of 
technological advances for decades with new and improved products. Included 
among Corning's important technological discoveries over the years are 
optical fiber for telecommunications, ceramic substrates for automotive and 
stationary emission control devices, photosensitive glasses for various 
markets and mass produced television bulbs and incandescent light bulbs. 
Recent developments include an electrically heated automotive pollution 
control substrate, an expanded line of optical communications amplifiers, 
dispersion shifted optical fiber, a glass ceramic magnetic memory disk and 
active matrix liquid-crystal display glasses. 

Alliances and acquisitions are utilized to leverage Corning's technologies 
and market position. Corning's extensive experience with alliances spans more 
than fifty years and includes jointly owned companies with The Dow Chemical 
Company in silicones, PPG Industries Inc. in glass block and foam glass, the 
Samsung Group and Asahi Glass in television bulbs, Siemens AG in 
opto-electronics, and Mitsubishi Heavy Industries Ltd. in stationary emission 
control devices. 

Corning has recently completed several major strategic acquisitions, the most 
significant of which was the acquisition of Damon Corporation ("Damon") in 
August 1993. The acquisition of Damon has provided significant operating 
synergies with MetPath Inc. ("MetPath") and is expected to provide additional 
operating synergies upon full integration of Damon. Corning has also 
completed acquisitions in the optical-fiber and optical-cable businesses and 
the science products business. On May 4, 1994, Corning announced that it had 
signed a definitive agreement to merge Maryland Medical Laboratory Inc., a 
privately owned Baltimore, Maryland firm specializing in clinical laboratory 
testing for hospitals and physicians, with its MetPath clinical laboratory 
testing operations. 

Quality is an important element of all of Corning's business strategies. This 
embodies an unwavering focus on satisfying the customer, continuous 
improvement of the processes which deliver products and services to the 
customer and creating an empowered workforce dedicated to serving the 
customer. 

                             RECENT DEVELOPMENTS 

First Quarter 1994 Results 
Corning's first quarter net income totaled $58 million, or $0.28 per share, 
compared with 1993's first quarter net income of $49.8 million, or $0.26 per 
share. Excluding the impact of a non-operating gain in 1993, net income and 
earnings per share for the first quarter 1994 were up 23 percent and 15 
percent, respectively, when compared to the same period last year. 

First quarter sales totaled $948.9 million, up 16 percent over 1993. 
Approximately half of the sales increase was due to the acquisition of Damon 
in August of 1993. The earnings improvement in the quarter was led by the 
optical-fiber and optical-cable and environmental substrate businesses. 

Equity company earnings of $16.5 million were more than double those of the 
prior year's first quarter. The improvements were due to a strong performance 
at Dow Corning Corporation ("Dow Corning") and the elimination of losses from 
Vitro Corning, S.A. de C.V. ("Vitro Corning"), which was divested in late 
1993. 

Disposition of Clinical Laboratory Testing Operations 
On April 4, 1994, MetPath sold the clinical laboratory testing operations of 
Damon in California for approximately $51 million in cash. No gain or loss 
will be recognized as a result of this transaction. The proceeds from the 
transaction will be used to retire a portion of the debt incurred in 
connection with the acquisition of Damon in August 1993. 

Creation of Environmental Testing Services Company 
On May 2, 1994, Corning and International Technology Corporation 
("International Technology") signed a definitive agreement to create a 
jointly owned company to provide environmental testing and related services. 
Under the terms of the agreement, Corning will transfer the net assets of its 
environmental testing laboratory business to the new company and 
International Technology will transfer the assets of its IT Analytical 
Services business to the new company. Corning and International Technology 
each will own 50 percent of the company. The transaction, which is subject to 
regulatory approval, is expected to close in the second or third quarter 
1994. Corning will account for its investment in the newly created company 
using the equity method of accounting for investments. The impact of the 
transaction is not expected to be material to Corning's financial statements. 

Acquisition of Maryland Medical Laboratory Inc. 
On May 4, 1994, Corning signed a definitive agreement to acquire all of the 
outstanding shares of Maryland Medical Laboratory Inc. and several affiliates 
(collectively, "Maryland Medical") for approximately 4.5 million shares of 
Corning Common Stock in a pooling-of-interests transaction. The transaction, 
which is subject to regulatory approval, is expected to close in the second 
or third quarter 1994. In connection with this transaction, Corning has 
granted to certain stockholders of Maryland Medical certain registration 
rights with respect to the shares of Corning Common Stock they receive. 
However, such stockholders may not sell the registered shares until the 
release of Corning's third quarter results. The impact of the transaction is 
not expected to be material to Corning's financial statements. 

Sale of Parkersburg Plant 
On May 23, 1994, Corning sold its Parkersburg, West Virginia glass-tubing 
products plant to Schott Scientific Glass, Inc., a subsidiary of Schott 
Corporation, for $57 million. The transaction is expected to result in a 
modest after-tax gain. 

See "Investment Considerations" for a discussion of certain factors to be 
considered in connection with an investment in the Preferred Securities, 
including circumstances under which interest payments on the Subordinated 
Debentures may be deferred for up to 60 months. 

                                 THE OFFERING 

                           
Securities Offered                ,000 of Corning Delaware's   % 
                              Convertible Monthly Income Preferred 
                              Securities, liquidation preference of $50 per 
                              share. Additionally, Corning and Corning 
                              Delaware have granted the Underwriters an 
                              option for 30 days to purchase up to an 
                              additional         Preferred Securities at 
                              the initial public offering price, less the 
                              Underwriters' Compensation, solely to cover 
                              over-allotments, if any. 

Dividends                     Dividends (as defined herein) on the 
                              Preferred Securities will be cumulative from 
                              the date of original issuance of the 
                              Preferred Securities and will be payable at 
                              the annual rate of   % of the liquidation 
                              preference of $50 per Preferred Security. 
                              Dividends will be paid monthly in arrears on 
                              the last day of each calendar month, 
                              commencing       , 1994. The proceeds from 
                              the offering of the Preferred Securities will 
                              be invested in the Subordinated Debentures. 
                              Interest payment periods on the Subordinated 
                              Debentures are monthly but may be extended 
                              from time to time by Corning for up to 60 
                              months, in which event Corning Delaware would 
                              be unable to make monthly dividend payments 
                              on the Preferred Securities during the period 
                              of any such extension. During such period, 
                              interest on the Subordinated Debentures and 
                              dividends on the Preferred Securities will 
                              compound monthly. The failure of holders of 
                              the Preferred Securities to receive dividends 
                              in full for 15 consecutive months would 
                              trigger the right of such holders to cause 
                              Corning Delaware to exchange all of the 
                              Subordinated Debentures for shares of Corning 
                              Series C Convertible Preferred Stock, par 
                              value $100 per share ("Corning Series C 
                              Preferred Stock"), and to distribute such 
                              shares to the holders of Preferred 
                              Securities. If the Preferred Securities 
                              remain outstanding for three months after the 
                              earlier of the date of notice of a Tax Event 
                              and the date that a vote is taken at any 
                              special partnership meeting called by the 
                              holders of the Preferred Securities to cause 
                              the exchange of all of the Subordinated 
                              Debentures for shares of Corning Series C 
                              Preferred Stock, then amounts available for 
                              distribution to holders may be reduced by the 
                              amount of Additional Taxes (as defined 
                              herein). See "Description of Securities 
                              Offered--Description of the Subordinated 
                              Debentures--Option to Extend Payment Period"

                              Stock." 

Liquidation Preference        $50 per Preferred Security, plus an amount 
                              equal to any accumulated and unpaid dividends 
                              (whether or not earned or declared). 

Conversion into Corning 
   Common Stock               Each Preferred Security is convertible 
                              through Corning Delaware at the option of the 
                              holder, at any time, unless previously 
                              redeemed or exchanged, into shares of Corning 
                              Common Stock, par value $.50 per share (the 
                              "Corning Common Stock"), at the rate of 
                                   shares of Corning Common Stock for each 
                              Preferred Security (equivalent to a 
                              conversion price of $     per share of 
                              Corning Common Stock), subject to adjustment 
                              in certain circumstances. Upon receiving an 
                              irrevocable notice by a holder of a Preferred 
                              Security to exercise its conversion right, 
                              Corning Delaware, on behalf of such holder, 
                              will exercise its option to convert such 
                              holder's allocable portion of the 
                              Subordinated Debentures into Corning Common 
                              Stock and will distribute such shares of 
                              Corning Common Stock to such holder in 
                              exchange for a corresponding portion of such 
                              holder's Preferred Securities. See 
                              "Description of Securities Offered--Preferred 
                              Securities--Conversion Rights." 

Redemption                    From time to time on and after      , 1998, 
                              the Preferred Securities will be redeemable, 
                              at the option of Corning Delaware, in whole 
                              or in part, for cash at the redemption prices 
                              set forth herein, together with accumulated 
                              and unpaid dividends (whether or not earned 
                              or declared) to the date fixed for 
                              redemption. The Preferred Securities are 
                              subject to mandatory redemption on the 30th 
                              anniversary of the date of original issuance 
                              at a redemption price of $50 per Preferred 
                              Security together with accumulated and unpaid 
                              dividends (whether or not earned or 
                              declared). If Preferred Securities are called 
                              for redemption, the conversion right will 
                              terminate two calendar days prior to the 
                              redemption date. 

Optional Exchange for 
  Corning Series C            Upon the occurrence of certain exchange 
  Preferred Stock             events, the holders of a majority of the 
                              aggregate liquidation preference of Preferred 
                              Securities then outstanding may, at their 
                              option, cause Corning Delaware to exchange 
                              all (but not less than all) of the 
                              Subordinated Debentures for shares of Corning 
                              Series C Preferred Stock at the Exchange 
                              Price (as defined under "Description of 
                              Securities Offered--Preferred 
                              Securities--Dividends") and distribute such 
                              shares to the holders of Preferred 
                              Securities. The exchange events are (a) the 
                              failure of holders of the Preferred 
                              Securities to receive, for 15 consecutive 
                              months, the full amount of dividend payments 
                              (other than as provided in clause (ii) under 
                              Voting Rights below), or (b) the occurrence 
                              of a Tax Event. 

                              The Corning Series C Preferred Stock will 
                              have dividend, conversion, optional 
                              redemption, and other terms substantially 
                              identical to the terms of the Preferred 
                              Securities, except that, among other things, 
                              the holders of Corning Series C Preferred 
                              Stock will have the right to elect two 
                              additional directors of Corning whenever 
                              dividends on the Corning Series C Preferred 
                              Stock are in arrears for 18 months (including 
                              for this purpose any arrearage with respect 
                              to the Preferred Securities) and the Corning 
                              Series C Preferred Stock will be perpetual 
                              and will not be subject to mandatory 
                              redemption. 

Guarantee                     Pursuant to a Guarantee Agreement (the 
                              "Guarantee"), Corning will unconditionally 
                              guarantee, to the extent set forth therein, 
                              (a) the payment of dividends (including any 
                              Additional Interest thereon, as defined 
                              herein) by Corning Delaware on the Preferred 
                              Securities, if, and to the extent declared 
                              from funds legally available therefor, (b) 
                              the redemption price of the Preferred 
                              Securities, and (c) payments on 

                              liquidation with respect to the Preferred 
                              Securities, to the extent of the assets of 
                              Corning Delaware available for distribution 
                              to holders of the Preferred Securities. The 
                              Guarantee will be unsecured and will be 
                              subordinated to all liabilities of Corning 
                              and will rank pari passu with the Series B 
                              Preferred Stock (as defined under 
                              "Description of Corning Capital Stock--Series 
                              Preferred Stock"). See "Description of

Voting Rights                 Generally, holders of the Preferred 
                              Securities will not have any voting rights. 
                              However, upon the failure of holders to have 
                              received, at the end of any period of 60 
                              consecutive months, dividends in full on the 
                              Preferred Securities for such 60-month 
                              period, the holders of the Preferred 
                              Securities will be entitled to appoint and 
                              authorize a Special General Partner to 
                              enforce Corning Delaware's rights under the 
                              Subordinated Debentures, enforce Corning's 
                              obligations under the Guarantee and declare 
                              and pay dividends on the Preferred Securities 
                              to the extent funds are legally available 
                              therefor. In addition, upon the occurrence of 
                              a Tax Event, holders of the Preferred 
                              Securities will be entitled to call a special 
                              partnership meeting for the purpose of 
                              deciding whether (i) to cause Corning 
                              Delaware to exchange all of the outstanding 
                              Subordinated Debentures for shares of Corning 
                              Series C Preferred Stock at the Exchange

                              for the Preferred Securities or (ii) to 
                              continue to hold the Preferred Securities, in 
                              which case amounts available for distribution 
                              to holders may be reduced. See "Description 
                              of Securities Offered--Preferred 
                              Securities--Dividends." 

Use of Proceeds               The proceeds to be received by Corning 
                              Delaware from the sale of the Preferred 
                              Securities will be invested in the 
                              Subordinated Debentures of Corning, which, 
                              after paying the expenses associated with 
                              this Offering, will use such funds to retire 
                              a significant portion of the Damon 
                              acquisition debt. See "Use of Proceeds." 

Subordinated Debentures       The Subordinated Debentures will have a 
                              maturity of 30 years and will bear interest 
                              at the rate of    % per annum, payable 
                              monthly in arrears. Corning has the right to 
                              select an interest payment period or periods 
                              longer than one month (during which period or 
                              periods interest will compound monthly), 
                              provided that any extended interest payment 
                              period does not exceed 60 months. If Corning 
                              selects an interest payment period longer 
                              than one month, it will be prohibited from 
                              paying dividends on any of its capital stock 
                              and making certain other restricted payments 
                              until monthly interest payments are resumed 
                              and all accumulated and unpaid interest 
                              (including any Additional Interest) on the 
                              Subordinated Debentures is brought current. 
                              Corning will have the right to make partial 
                              payments of such interest during the extended 
                              interest payment period. The Subordinated 
                              Debentures are convertible into shares of 
                              Corning Common Stock at the option of Corning 
                              Delaware and exchangeable for shares of 
                              Corning Series C Preferred Stock upon the 
                              exchange events referred to above. On and 
                              after       , 1998, Corning may prepay the 
                              Subordinated Debentures, in whole or in part. 
                              The payment of the principal and interest on 
                              the Subordinated Debentures will be 
                              subordinated in right of payment to all 
                              Senior Indebtedness (as defined under 
                              "Description of Securities 
                              Offered--Description of the Subordinated 
                              Debentures--Subordination") of Corning. As of 
                              March 27, 1994, Corning had $1.9 billion of 
                              Senior Indebtedness outstanding. 



SUMMARY FINANCIAL INFORMATION

has been derived from the consolidated financial statements of Corning. The 
summary financial data set forth below for Corning for the 1989 through 1993 
fiscal years are derived from its audited financial statements. The summary 
financial data set forth below for the first twelve weeks of 1994 and 1993 
are derived from Corning's unaudited financial statements, which in the 
opinion of management contain all adjustments (consisting only of normal 
recurring items) necessary for the fair presentation of this information. The

acquisitions of Damon and Costar Corporation ("Costar"), and several other 
completed 1993 transactions (collectively, the "Transactions"). Such pro 
forma data assume the Transactions had been completed on January 4, 1993. The 
unaudited pro forma combined income statement data set forth below are 
derived from, and should be read in conjunction with, the unaudited pro forma 
combined 1993 statement of income included elsewhere in this Prospectus and 
the historical financial statements of Corning and Damon incorporated by

USE OF PROCEEDS 

Corning Delaware will invest the proceeds from the Offering in the 
Subordinated Debentures. Corning, after payment of the Underwriters' 
Compensation (as defined under "Underwriting") and other expenses of the 
Offering, will use the net proceeds from the sale of the Subordinated 
Debentures to Corning Delaware of $           ($        if the Underwriters' 
over-allotment option is exercised in full) to retire a significant portion 
of the debt incurred in the 1993 acquisition of Damon. The Damon debt bears a 
variable interest rate based on the London Interbank Offered Rate and matures 
on December 31, 1995. For information concerning the Damon transaction, see 
"Business of Corning--Laboratory Services." 

                          INVESTMENT CONSIDERATIONS 

Prospective purchasers of Preferred Securities should carefully review the 
information contained elsewhere in this Prospectus and should particularly 
consider the following matters: 

Subordinate Obligations Under Guarantee and Subordinated 
Debentures. Corning's obligations under the Guarantee are subordinate and 
junior in right of payment to all liabilities of Corning and the obligations 
of Corning under the Subordinated Debentures are subordinate and junior in 
right of payment to all Senior Indebtedness of Corning. See "Description of 
Securities Offered--Description of the Guarantee" and "Description of 
Securities Offered--Description of the Subordinated 
Debentures--Subordination." 

Option to Extend Payment Periods. Corning has the right to extend interest 
payment periods on the Subordinated Debentures for up to 60 months, and, as a 
consequence, monthly dividends on the Preferred Securities would be deferred 
(but will continue to compound monthly) during any such extended interest 
payment period. In the event that Corning exercises this right, Corning may 
not declare dividends on any shares of its capital stock. However, in the 
event such a deferral continues for more than 15 months, the holders of a 
majority of liquidation preference of the Preferred Securities then 
outstanding may cause the exchange of all of the Preferred Securities for 
Corning Series C Preferred Stock at the Exchange Price. See "Description of 
Securities Offered--Description of the Subordinated Debentures--Option to 
Extend Interest Payment Period." 

For a discussion of the taxation of such an exchange to holders, including 
the possibility of holders recognizing additional taxable income from the 
accrued dividends received in connection with the exchange, see "Certain 
Federal Income Tax Considerations--Exchange of Preferred Securities for 
Corning Series C Preferred Stock." 

Should an extended interest payment period occur, Corning Delaware, except in 
very limited circumstances, will continue to accrue income for  U.S. federal 
income tax purposes which will be allocated, but not distributed, to holders 
of record of Preferred Securities. As a result, such holders will include 
such interest in gross income for United States federal income tax purposes 
in advance of the receipt of cash, and will not receive the cash related to 
such income if such a holder disposes of its Preferred Securities prior to 
the record date for payment of dividends. See "Certain Federal Income Tax 
Considerations--Original Issue Discount." 

Exchange Event. In the case of a Tax Event, the holders of a majority of 
liquidation preference of Preferred Securities then outstanding will have the 
right to cause all of the Preferred Securities to be exchanged for Corning 
Series C Preferred Stock at the Exchange Price. However, in the event that 
the Preferred Securities are not exchanged, the amounts available for 
distribution to holders may be reduced. Under certain circumstances giving 
rise to a Tax Event, the exchange of Preferred Securities for Corning Series 
C Preferred Stock would be a taxable transaction in which exchanging holders 
recognize gain. See "Certain Federal Income Tax Considerations--Exchange of 
Preferred Securities for Corning Series C Preferred Stock." 

CAPITALIZATION 

The following table sets forth (i) the actual capitalization of Corning at 
March 27, 1994, and (ii) the pro forma capitalization of Corning as of such 
date after giving effect to the Offering, assuming no exercise of the 
Underwriters' over-allotment option. The table should be read in conjunction 
with the financial statements of Corning incorporated by reference in this 
Prospectus. See "Use of Proceeds," "Selected Consolidated Financial Data," 
"Corning Unaudited Pro Forma Combined 1993 Statement of Income," 
"Management's Discussion and Analysis of Financial Condition and Results of 
Operations," and "Description of Securities Offered--Preferred Securities."

              RATIOS OF EARNINGS TO COMBINED FIXED CHARGES AND 
                          PREFERRED STOCK DIVIDENDS 

The following table sets forth the historical ratio of earnings to combined 
fixed charges and preferred stock dividends of Corning for the periods 
indicated: 


                                                                     Fiscal Year Ended

For the purposes of computing the ratio of earnings to combined fixed charges 
and preferred stock dividends, earnings consist of (1) income before taxes on 
income, before equity in earnings and minority interest and before fixed 
charges (excluding interest capitalized during the period), (2) Corning's 
share of pre-tax earnings of fifty-percent owned companies, (3) Corning's 
share of pre-tax earnings of greater than fifty-percent owned unconsolidated 
subsidiaries, (4) dividends received from less than fifty-percent owned 
companies and Corning's share of losses of such companies, if any, if any 
debt of such companies is guaranteed by Corning and (5) previously 
capitalized interest amortized during the period; fixed charges consist of 
(1) interest on indebtedness, (2) amortization of debt issuance costs, (3) a 
portion of rental expenses which represent an appropriate interest factor, 
(4) Corning's share of the fixed charges of fifty-percent owned companies and 
(5) fixed charges of greater than fifty-percent owned unconsolidated 
subsidiaries; and preferred dividends include the amount of pre-tax income 
required to pay preferred dividends on an after-tax basis.

(a) Per share amounts have been adjusted for the 2-for-1 stock split 
effective January 13, 1992. 
(b) Includes a special dividend of $.15 per common share in the fourth 
quarter of 1991. 

Corning has regularly paid cash dividends since 1881 and expects to continue 
to pay cash dividends. Corning's quarterly cash dividend is currently $.17 
per share of Corning Common Stock. The payment of dividends is subject to the 
preferential dividend rights of any outstanding Series Preferred Stock of 
Corning (as defined under "Description of Corning Capital Stock--Series 
Preferred Stock"). Corning and its majority-owned subsidiaries would also be 
prohibited from paying dividends on Corning Common Stock at any time when 
interest payments had not been made in full on the Subordinated Debentures or 
when dividends had not been paid in full on the Preferred Securities. Since 
the declaration and payment of future dividends on Corning's capital stock 
will be based on a number of factors considered by Corning's Board of 
Directors, including current and prospective earnings, financial condition 
and capital requirements, and such other factors as the Board of Directors 
may deem relevant, there can be no assurance that dividends on Corning Common 
Stock will be paid in the future. See "Description of Corning Capital 
Stock--General--Dividend Rights and Restrictions."

The accompanying notes are an integral part of these statements. 

(a) During the first quarter 1993, Corning recognized a non-operating gain 
totaling $4.2 million ($2.6 million after-tax). 

(b) Effective January 4, 1993, Corning and its subsidiaries adopted Financial 
Accounting Standard No. 109, " Accounting for Income Taxes" ("FAS 109") and 
Financial Accounting Standard No. 112, "Employers' Accounting for 
Postemployment Benefits" ("FAS 112"). The impact of adopting FAS 109 and FAS 
112 was not material to the financial statements. 

(c) In 1993, Corning recognized net non-recurring losses from consolidated 
operations totaling $202.8 million ($117.9 million after-tax and minority 
interest), including a non-operating gain of $4.2 million ($2.6 million 
after-tax); a charge of $36.5 million ($22.0 million after tax) to reflect 
the settlement and related legal expenses incurred in the compromise 
agreement between MetPath and the Civil Division of the Department of 
Justice; and a restructuring charge totaling $170.5 million ($98.5 million 
after tax and minority interest) as a result of costs to integrate the Damon 
and Costar acquisitions and a planned company-wide restructuring program 
announced October 6, 1993 to reduce overhead costs during 1994. 
Corning also recorded a $203.1 million reduction in equity earnings as a 
result of a charge taken by Dow Corning related to breast-implant litigation 
and a $9.5 million reduction in equity earnings as a result of a 
restructuring charge taken by Vitro Corning. 

(d) In 1992, Corning recognized net non-operating gains from consolidated 
operations totaling $7.0 million ($21.7 million after- tax), including a gain 
of $10.1 million (before- and after-tax) from the sale of an additional 
equity interest in Corning Japan K.K. and a pre-tax loss of $7.3 million 
($9.0 million after-tax gain) from the formation of the consumer housewares 
venture with Vitro S.A. ("Vitro"). Corning also recorded a provision of $63.3 
million ($32.1 million after-tax of $22.9 million and minority interest of 
$8.3 million) as a result of Corning Vitro Corporation's ("Corning Vitro") 
decision to restructure its Brazilian operations. 
Corning also recognized a $37.7 million reduction in equity earnings which 
included $24.5 million of costs associated with Dow Corning's terminated 
breast implant business and $13.2 million of restructuring charges associated 
with Dow Corning's exit from its Brazilian operations and other 
cost-reduction programs. 

(e) Effective December 30, 1991, Corning and its subsidiaries adopted 
Financial Accounting Standard No. 106, "Employers' Accounting for 
Postretirement Benefits Other than Pensions" ("FAS 106"). The cumulative 
effect of adopting FAS 106 resulted in a charge of $294.8 million (after-tax 
and minority interest), or $1.56 per share, in 1992. In addition, an $8.2 
million gain, or $0.04 per share, from an equity company's adoption of FAS 
109 was recognized in 1992. 

(f) In 1991, the Company recognized net non-operating gains from consolidated 
operations totaling $8.1 million ($14.6 million after-tax) which included a 
gain of $5.3 million (before- and after-tax) on the sale of a less than 10% 
equity interest in Corning Japan. The Company also recognized an $8.2 million 
reduction in equity earnings to reflect a charge recorded by Dow Corning for 
costs associated with its breast implant business. 

(g) In 1990, the Company recognized non-operating gains totaling $69.2 
million ($29.2 million after-tax) on the sales of certain investments, 
including a gain on the sale of substantially all the Company's investment in 
Iwaki Glass Company Ltd. totaling $51.1 million ($19.4 million after-tax). 

(h) In 1989, the Company recognized non-operating gains totaling $107.1 
million ($61.9 million after-tax), including a gain on the sale of its 50% 
interest in Ciba Corning Diagnostics Corp. of $75.7 million ($41.0 million 
after-tax) and a gain of $21.7 million ($13.7 million after-tax) related to 
patent infringement matters in the optical-fiber business. 
Also in 1989, the Company provided $54.4 million ($45.0 million after-tax) 
for the repositioning of certain businesses and facilities. The provision 
related primarily to consumer product operations worldwide, and to certain 
other operations in Europe. 

(i) Per share amounts have been adjusted for the 2-for-1 stock split 
effective January 13, 1992. 

(j) Includes special dividends of $0.15 and $0.1125 per common share in 1991 
and 1989, respectively. 

CORNING UNAUDITED PRO FORMA COMBINED 1993 STATEMENT OF INCOME 

The Unaudited Pro Forma Combined 1993 Statement of Income (the "Pro Forma 
Information") is presented to reflect the estimated impact on Corning's 1993 
Statement of Income of the following Transactions completed in 1993: 

* The acquisition of Damon in August 1993, at a total purchase price of 
approximately $405 million, including acquisition expenses. The transaction 
has been accounted for as a purchase. 

* The merger with Costar in September 1993 in which Corning acquired all of 
the outstanding shares of common stock and options to purchase common stock 
of Costar for approximately 5.5 million shares of Corning Common Stock and 
options to purchase approximately 300,000 shares of Corning Common Stock. 
This acquisition has been accounted for as a pooling of interests. Corning's 
consolidated financial statements for periods prior to the acquisition have 
not been restated since the acquisition is not material to Corning's 
financial position or results of operations. 

* The transaction with Unilab Corporation ("Unilab"), which was completed in 
November 1993, and other completed acquisitions (collectively, the "Other 
Completed Transactions") which individually and in the aggregate are not 
significant. The Unilab transaction is described in Note 4. 

The 1993 Unaudited Pro Forma Combined Statement of Income assumes that the 
Transactions had been completed on January 4, 1993. The impact of the 
Offering is not material to the 1993 pro forma results. 

The Pro Forma Information gives effect only to the adjustments set forth in 
the accompanying notes and does not reflect any synergies anticipated by 
Corning management as a result of these acquisitions. The Pro Forma 
Information is not necessarily indicative of the results of operations which 
would have been achieved had the Transactions been completed as of the 
beginning of the period presented, nor is it necessarily indicative of 
Corning's future results of operations. 

Corning has completed or has pending several transactions in 1994 which 
individually and in the aggregate are not significant to Corning's 
consolidated financial statements. As such, pro forma data on these 
transactions are not presented. 

The Pro Forma Information should be read in conjunction with the historical 
financial statements of Corning and Damon incorporated by reference into this 
Prospectus.

        NOTES TO UNAUDITED PRO FORMA COMBINED 1993 STATEMENT OF INCOME 

Note 1--Basis of Presentation: 
The Unaudited Pro Forma Combined Statement of Income reflects the Company's 
results of operations for the year ended January 2, 1994, on a pro forma 
basis assuming the Transactions had been completed as of January 4, 1993. 

Corning management believes that the assumptions used in preparing the Pro 
Forma Information provide a reasonable basis for presenting all of the 
significant effects of the Transactions, that the pro forma adjustments give 
appropriate effect to those assumptions and that the pro forma adjustments 
are properly applied in the Pro Forma Information. 

Note 2--Pro Forma Adjustments: 
(a) The pro forma adjustment to cost of sales represents the increase in 
amortization of the excess of cost over fair value of tangible net assets 
acquired in the Damon transaction and the Other Completed Transactions of 
$5.7 million and $1.8 million, respectively, for the year ended January 2, 
1994. 

The excess of cost over fair value of tangible net assets acquired in the 
Damon transaction was $552 million. The excess of cost over fair value of 
tangible net assets acquired has been allocated to goodwill with a life of 
forty years. Management believes that fair value approximates book value for 
all tangible assets. 

(b) The pro forma adjustment represents the elimination of one-time 
restructuring costs of $47.1 million related to closing MetPath facilities as 
a result of the integration of Damon and MetPath and $7.9 million of Costar 
transaction costs recorded in Corning's results for the year ended January 2, 
1994. 

(c) The pro forma adjustment to interest expense represents the interest on 
the debt incurred in connection with the Damon transaction and the Other 
Completed Transactions of $11.9 million and $2.3 million, respectively, for 
the year ended January 2, 1994. The weighted average interest rate on the 
debt incurred in connection with the Damon transaction is 4.9% and on the 
Other Completed Transactions ranges from 3.5% to 6.7%. 

Corning financed the Damon acquisition and the refinancing of approximately 
$167 million of indebtedness of Damon under short-term financing agreements 
entered into with certain banks to effect this transaction. During the third 
quarter of 1993, Corning refinanced a portion of this short-term financing by 
issuing approximately $200 million of long-term debt. The pro forma 
adjustment for interest expense related to the Damon transaction is 
calculated as the weighted average of short-term and long-term interest 
rates. The impact of the Offering is not material to the 1993 pro forma 
results. 

(d) The pro forma adjustment represents the elimination of approximately $1 
million of one-time costs incurred by Damon in connection with a terminated 
merger agreement with National Health Laboratories Incorporated ("NHL") which 
were charged to Damon's results of operations for the seven months ended July 
31, 1993. 

(e) The pro forma adjustment to tax expense represents the tax effect of the 
adjustments detailed in notes (a), (b), (c), and (d) above. This adjustment 
is calculated at Corning's historical effective tax rate. 

(f) The pro forma adjustment to minority interest represents the applicable 
minority interest on the historical earnings and pro forma adjustments of the 
Other Completed Transactions. 

(g) The pro forma adjustment to weighted average shares outstanding 
represents the issuance of 5.5 million shares to complete the Costar merger 
in September 1993. 

Note 3--Earnings Per Share: 
Earnings per common share are computed by dividing net income less preferred 
dividends by the weighted average number of common shares outstanding during 
each period. Preferred dividends amounted to $2.1 million during the year 
ended January 2, 1994. 

Note 4--Unilab Transaction: 
Corning, through a wholly owned subsidiary, owned 43% of Unilab. In November 
1993, Corning acquired 100 percent of certain Unilab facilities in exchange 
for a majority of the Unilab shares owned by Corning, the assumption of 
approximately $70 million of Unilab debt and Corning's investment in J.S. 
Pathology PLC ("J.S. Pathology"). Corning retained a 12% equity investment in 
Unilab. 

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF 
                FINANCIAL CONDITION AND RESULTS OF OPERATIONS 

First Quarter 1994 Performance 
Net sales for the first quarter 1994 totaled $948.9 million, up 16 percent 
from the same period last year. Approximately half of the sales increase was 
due to the 1993 acquisition of Damon. The other 1993 acquisitions also 
contributed positively to sales growth. Net income was $58.0 million ($0.28 
per share) for the first quarter of 1994 compared to $49.8 million ($0.26 per 
share) for the first quarter 1993. Excluding the impact of a non-operating 
gain in 1993, net income and earnings per share for the first quarter 1994 
were up 23 percent and 15 percent, respectively, when compared to the same 
period last year. 

Earnings from consolidated operations for the first quarter 1994, excluding 
the non-operating gain in 1993, increased 4 percent over the same period last 
year. 

First quarter 1994 equity in earnings of associated companies was $16.5 
million compared with $7.2 million in the same period last year. Increased 
earnings were due to strong operating performance at Dow Corning and the 
elimination of losses from Vitro Corning, which was divested in late 1993. 

  Segment Overview 
Corning's products and services are grouped into four industry segments: 
Specialty Materials, Communications, Laboratory Services and Consumer 
Products. Sales and earnings for the first quarter 1994 increased in all 
segments except laboratory services which was negatively impacted by severe 
winter weather in the eastern half of the United States. 

Sales and earnings growth in the specialty materials segment was led by the 
environmental products business which experienced increased demand for 
ceramic substrates in its North American market. The science products 
business, which included results of Corning Costar Corporation which was 
acquired in 1993, and the optical products business also contributed to the 
earnings growth in this segment. 

Increased sales and earnings in the communications segment were primarily due 
to strong volume gains in the optical-fiber and optical-cable businesses. 
Sales and earnings in the conventional video components and projection video 
businesses also contributed to the growth in this segment. Earnings 
improvements were offset somewhat by continued development spending in the 
advanced display products and ceramic memory disk businesses. 

First quarter sales of the laboratory services segment improved significantly 
over the prior year primarily as a result of the 1993 acquisition of Damon. 
First quarter segment earnings were level with 1993. Sales and earnings of 
this segment were negatively impacted by the severe winter weather in the 
eastern half of the United States. The Damon acquisition contributed 
positively to the operating results of this segment; however, the gain was 
offset by increased goodwill amoritization resulting from the acquisition. 

Sales and earnings gains in the consumer products segment were driven by 
improved domestic volume. Strong manufacturing performance and a continued 
focus on cost controls also contributed to the earnings growth in this 
segment. 

At year end 1993, Corning had restructuring and acquisition integration 
reserves totaling $232.5 million, of which $155 million were short-term and 
$77.5 million were long-term. Corning's restructuring and integration 
programs are proceeding as planned. At the end of April 1994, the activities 
associated with the corporate-wide restructuring program were more than half 
complete and MetPath and Damon laboratories had been fully integrated in five 
of ten primary locations. Of the $199.1 million in restructuring reserves at 
the end of the first quarter, $128.4 million were classified as short-term 
and $70.7 million were classified as long-term. The majority of these 
reserves are expected to be paid in cash for severance-related items and 
facility exit expenses. The restructuring program and the integration of 
Damon are expected to be substantially complete by the end of the third 
quarter 1994. 

  Taxes on Income 
Corning's effective tax rate was 37% in the first quarter 1994 and 34% in the 
first quarter 1993. The change in the effective tax rate was primarily due to 
the increase in the U.S. corporate statutory tax rate (which was effective in 
the third quarter 1993) and an increase in non-deductible amortization of 
intangibles and other expenses. 

  Liquidity and Capital Resources 
Corning's working capital of $452.5 million at March 27, 1994 was relatively 
unchanged from $451.4 million at the end of 1993. The ratio of current assets 
to current liabilities of 1.4 was also unchanged from 

year-end 1993. Corning's long-term debt as a percentage of total capital was 
42% at the end of the first quarter compared to 45% at year-end 1993. The 
improvement in this ratio is due primarily to the issuance of common stock in 
February 1994. Corning intends to repay a significant portion of the 
remaining $400 million Damon acquisition debt with the proceeds from the sale 
of the Damon laboratories in California and the net proceeds from this 
Offering. 

  Cash Flows 
Cash and short-term investments declined from year-end 1993 by $62.6 million 
due to operating and investing activities which used cash of $63.8 million 
and $334.7 million, respectively, offset by financing activities which 
provided cash of $335.7 million. Net cash used in operating activities 
increased in the first quarter 1994 compared to the same period in 1993 due 
primarily to an increase in accounts receivable. Net cash used in investing 
activities increased during the same period due to the acquisition of assets 
from Northern Telecom Limited and the purchase of Corning Vitro stock from 
Vitro. Net cash provided by financing activities increased in the first 
quarter 1994 over 1993 primarily as a result of the issuance of common stock 
in February 1994 to finance the Northern Telecom and Vitro transactions. 

1993 Performance 
Corning's consolidated sales of $4,004.8 million in 1993 were up 8% from 
1992. Approximately half of this growth was attributable to recent 
acquisitions, with the remaining growth led by the Laboratory Services and 
Communications segments. Consolidated sales in 1992 increased 14% from 1991 
also as a result of strong performance by the Laboratory Services segment, 
due in part to acquisitions, and the Communications segment. 

As a result of non-recurring charges, Corning incurred a net loss in both 
1993 and 1992. 

Net losses totaled $15.2 million ($0.09 per common share) in 1993 and 
included net non-recurring charges against consolidated operations totaling 
$202.8 million ($117.9 million after tax and minority interest). These 
charges included $36.5 million for the settlement and related legal expenses 
incurred in the compromise agreement between MetPath, Corning's 
clinical-testing business, and the Civil Division of the Department of 
Justice; a restructuring charge of $170.5 million as a result of costs to 
integrate the Damon and Costar acquisitions and a planned company-wide 
program to reduce assets and overhead costs during the next year; and a 
non-operating gain of $4.2 million. Corning also recorded a $203.1 million 
reduction in equity earnings as a result of a charge taken by Dow Corning 
related to breast-implant litigation and a $9.5 million reduction in equity 
earnings as a result of a restructuring charge taken by Vitro Corning. 

As a result of non-recurring charges in 1992, Corning recorded a net loss of 
$12.6 million ($0.08 per common share) compared with net income of $316.8 
million ($1.69 per common share) in 1991. Non-recurring charges in 1992 
included an after-tax charge of $294.8 million ($1.56 per common share) to 
reflect the cumulative effect of adoption of Financial Accounting Standard 
No. 106, "Employers' Accounting for Postretirement Benefits Other than 
Pensions," (FAS 106) for all consolidated and equity companies and a gain of 
$8.2 million ($0.04 per common share) to reflect Corning's equity in the 
cumulative effect of adoption of Financial Accounting Standard No. 109, 
"Accounting for Income Taxes," by an equity company. 

Earnings from consolidated operations, excluding non-recurring gains and 
losses, declined 4% in 1993 when compared with 1992. This decline was 
principally due to weak performance in the Consumer Products segment and the 
cyclical businesses of the Specialty Materials segment, especially those in 
Europe. In addition, lower prices reduced the rate of growth in both the 
MetPath clinical-testing business and the optical-fiber and optical-cable 
businesses. Earnings were also impacted by increased interest expense on debt 
incurred to finance the acquisition of Damon and capital expansion programs. 

Equity earnings in 1993, excluding non-recurring charges, were up 14% over 
1992 primarily as a result of improved performance at Samsung-Corning 
Company, Ltd. ("Samsung-Corning") and Dow Corning. These gains were offset 
somewhat by a decline in earnings from the optical-fiber equity companies and 
continued poor operating performance at Vitro Corning. 

In 1992, earnings from consolidated operations increased 12% over 1991 with 
the growth led by the Communications and Laboratory Services segments. Equity 
earnings in 1992 declined substantially from 1991 levels due to non-recurring 
charges and reduced operating earnings at Dow Corning and losses at both 
Vitro Corning and Unilab. 

Segment Overview 
In the following discussion, the sales and earnings of Corning's equity 
affiliates are discussed in terms of the Company's four industry segments.

(2) Both 1992 and 1993 include the incremental expense due to the adoption
of FAS 106 which totaled $8.5 million in 1992.

(3) Includes $26.5 million of restructuring charges. 

Consolidated operations: 

Consolidated sales of this segment have increased modestly in each of the 
last three years. The increase in 1993 segment sales resulted primarily from 
the acquisition of Costar. Excluding the impact of restructuring charges, 
earnings have also increased over the past three years. Restructuring charges 
in 1993 included $8 million of transaction costs related to the Costar 
acquisition and $18.5 million of severance and other costs to restructure 
operations both in the United States and in Europe. 

Segment performance in 1993 was led by the science-products businesses. Sales 
and earnings of the science-products businesses were up significantly over 
1992 reflecting improved manufacturing efficiencies in both the plastic and 
glass product lines, continued strength in the market for plastic science 
products, and the acquisition of Costar. In the third quarter, Corning 
acquired Costar, a manufacturer of disposable plastic products, membrane 
filters, cartridge and filtration equipment used in life-science laboratories 
and industrial plants throughout the world. With this acquisition, Corning 
more than doubled the size of its existing plastics business. The modest 
sales growth of the science-products businesses in 1992 over 1991 was 
attributable to the growth in the market for plastic products. Earnings gains 
in 1992 were primarily due to manufacturing efficiencies in the plastics 
line. 

Sales of the environmental-products business in 1993 were up slightly over 
1992 due primarily to strong sales in North America offset by declines in the 
European markets. Legislation mandating the use of pollution-control devices 
continues to drive the increase in demand for automotive and diesel 
substrates. Earnings in 1993 were down when compared with 1992 due to the 
weak European economies. Sales and earnings of this business increased in 
1992 over 1991 due to volume and manufacturing efficiency gains. 

Sales of Corning's other Specialty Materials businesses, consisting of 
optical products, lighting, and other advanced materials, declined in 1993 
and 1992. Sales of these businesses in 1993 increased in the United States 
but were down significantly in Europe due to weak economic conditions. Growth 
in the optical products business continues to be negatively impacted by 
plastic optical products. Earnings of these businesses in total declined in 
1993 and 1992. 

In December 1993, Corning sold its process systems business which had annual 
sales of approximately $40 million. Both the operating results of this 
business and impact of this transaction were not material.

(1) Before equity in changes in accounting methods. 

Corning is an investor in and receives income from a number of equity 
companies in the Specialty Materials segment, including Dow Corning, 
Pittsburgh Corning Corporation and Pittsburgh Corning Europe, N.V. Dow 
Corning's sales increased in each of the last three years. Corning's equity 
in earnings of Dow Corning was reduced by $203.1 million, $24.5 million and 
$8.2 million in 1993, 1992 and 1991, respectively, as a result of charges 
taken by Dow Corning related to its terminated breast-implant business and by 
restructuring charges totaling $13.2 million in 1992. Excluding special 
charges, earnings were up 

in 1993 following a decline in 1992 due to improved operating performance at 
Dow Corning. The 1992 decline was caused by weak worldwide economies and the 
increase in postretirement benefit expense caused by the adoption of FAS 106 
at Dow Corning. 

In September 1993, Dow Corning announced that a proposal had been developed 
to settle, on a global basis, matters involved in litigation over 
silicone-gel breast-implant products. In March 1994, Dow Corning, along with 
other defendants and representatives of breast implant litigation plaintiffs, 
signed a Breast Implant Litigation Settlement Agreement (the "Settlement 
Agreement"). Under the Settlement Agreement and related agreements, industry 
participants would contribute approximately $4.2 billion over a period of 
more than thirty years to establish several special purpose funds. See 
"Business of Corning--Recent Developments--Breast Implant Litigation." 

Dow Corning recorded an accounting charge of $415 million after tax in the 
fourth quarter of 1993 which included Dow Corning's best estimate of the net 
present value of its potential liability for breast-implant litigation based 
on current settlement negotiations, and also included provisions for legal, 
administrative and research costs related to breast implants. As 
breast-implant litigation settlement negotiations continue, additional facts 
and circumstances may develop which may require Dow Corning to revise its 
current estimate or record additional provisions. 

Corning does not believe that its share of any additional accounting charge 
taken by Dow Corning resulting from the proposed settlement will have a 
material adverse effect upon Corning's overall financial condition. However, 
it is possible that Corning's share of any such charge taken by Dow Corning 
will have a material adverse effect upon Corning's earnings in the quarter in 
which any such charge is recognized by Dow Corning. 

Outlook: 

The modest positive sales trend experienced in this segment over the last 
three years is expected to continue in 1994. Sales growth is expected to come 
primarily from the continued strength of the plastics science-products 
business and from the ceramic substrates business as new and pending 
environmental regulations become effective in the United States and foreign 
countries. Although performance of this segment will continue to be affected 
by the European and Japanese economies, consolidated earnings are expected to 
grow modestly due primarily to continued cost control and restructuring 
measures and manufacturing efficiencies. Dow Corning's sales and operating 
earnings are expected to improve in 1994.

FAS 106 which totaled $9.1 million in 1992. 
(2)  Includes $10.7 million of restructuring charges. 

Consolidated operations: 

Consolidated sales in this segment have grown during the past three years 
driven by continued strong growth in worldwide demand for optical fiber and 
optical cable. The conventional-video components and advanced display 
products businesses also experienced strong sales increases in 1993. 
Excluding restructuring charges, earnings were up in 1993 due to volume 
growth and improved manufacturing performance in the advanced display 
products and conventional-video components businesses and a modest increase 
in earnings of the optical-fiber and optical-cable businesses. Sales and 
earnings in the projection-video business reached record levels in 1993. 
Restructuring charges of $10.7 million in 1993 included severance and other 
costs associated with an overhead reduction program. Segment earnings in 1992 
increased over 1991. 

Sales of Corning's optical-fiber and optical-cable businesses increased 
significantly in both 1993 and 1992. Market growth has been led by the 
increased use of fiber-optic cable in the feeder portions of telephone 
networks and the rapidly growing use of fiber in cable-television systems. 
Despite record volume growth, earnings of the optical-fiber and optical-cable 
businesses increased only slightly due to aggressive pricing to secure 
long-term optical-cable supply contracts. Earnings in 1992 increased over 
1991. Corning continues to invest in the development of several businesses in 
this segment which provide a variety of optical components to bring optical 
fiber to the home. 

In 1993, Corning increased its acquisition activity in this segment to expand 
its market for optical-fiber products and related optical components. In the 
third quarter of 1993, Siecor Corporation ("Siecor") acquired the 
telecommunications business of GTE Control Devices Incorporated which 
manufactures 

single- and multi-line network interface devices, solid state protection 
devices for central office and building entrance terminals, and optical 
hardware products. In February 1994, Corning and Siecor acquired the assets 
relating to the optical-fiber and optical-cable businesses of Northern 
Telecom Limited for $130 million in a transaction accounted for as a 
purchase. Northern Telecom is a major supplier of optical fiber and optical 
cable to Canadian and international markets. 

Sales in the conventional-video components and projection-video businesses 
increased significantly in 1993. The recovering U.S. television market and a 
shift in product mix from medium to larger size video components contributed 
to the strong sales increase. Sales in 1992 increased over 1991. Earnings 
were up in 1993 and 1992 as a result of higher volume and continuing 
manufacturing efficiency improvements. 

Sales in the advanced display products business, which produces 
liquid-crystal display glass, increased significantly in both 1993 and 1992. 
As a result of the growth in sales and solid manufacturing gains, this 
business experienced profitability for the first time in 1993 despite 
continued significant investment in research and development. In 1993, 
Corning began construction of melting units in Japan and in the United States 
which will significantly increase production capacity to meet the demands of 
this growing market. 

In 1993, Corning and Seagate Technology, Inc. ("Seagate") entered into the 
first major sales contract for Corning's new MemCor(tm) glass-ceramic memory 
disk which is used for high-performance disk drives in computers. This 
product significantly increases storage capacity and, because of its 
strength, improves reliability. Although the Seagate contract represents an 
important milestone in the development of this product, the profitability of 
this business will continue to be impacted by significant development 
spending. 

Sales of Biosym Technologies Inc. ("Biosym"), which was acquired in the third 
quarter of 1992, contributed to the sales growth of this segment. Biosym 
specializes in the development, marketing, and support of computer-aided 
molecular design software. Biosym's profitability was impacted by the weak 
economies in Japan and Europe and a slowdown in sales to pharmaceutical 
companies caused by uncertainty surrounding the impact of health-care reform.

Samsung-Corning, a South Korean manufacturer, produces glass panels and 
funnels for entertainment television and display monitors. Samsung-Corning's 
sales and earnings increased in 1993 and 1992. The 1993 increase in sales and 
earnings reflected higher volumes and share gains due to the strengthening 
yen along with reduced financing costs. The 1992 increase was primarily a 
result of increased sales and improved manufacturing performance. In 1993, 
Samsung-Corning completed a transaction which will expand its manufacturing 
capacity into Eastern Europe. 

Sales and earnings of Corning's optical-fiber equity companies declined in 
1993 due primarily to a decrease in volume and pricing pressures felt most 
heavily in Europe. Earnings were flat in 1992 compared with 1991 primarily as 
a result of adverse market conditions in the United Kingdom. 

Outlook: 

Segment performance is expected to improve in 1994. Sales volumes in the 
optical-fiber and optical-cable businesses are expected to continue to grow, 
although the rate of growth in earnings will continue to be impacted by 
worldwide pricing pressures. Sales and earnings of the advanced display 
products business are expected to continue their rapid growth trend. Sales 
and earnings in the conventional-video components and projection-video 
businesses are expected to continue their upward trend. Equity earnings in 
this segment are expected to decline due to the impact of two major glass 
furnace repairs on Samsung-Corning sales offset by a slight improvement in 
the optical-fiber equity companies.

(1) Includes a $36.5 million charge for the MetPath settlement and $58.5 
million of restructuring charges. 

Consolidated operations: 

Consolidated sales in this segment achieved record levels in each of the last 
three years, reflecting the strong performance trend in existing businesses 
and the impact of strategic acquisitions. Earnings were significantly 
impacted by non-recurring charges in 1993. Excluding these charges, earnings 
increased, but at a slower pace in 1993 than in prior years as a result of 
pricing pressures and significant uncertainty in the health care industry. 

In August 1993, MetPath completed the acquisition of Damon, a 
clinical-testing business. In addition, in November 1993, MetPath completed a 
transaction with Unilab which resulted in the acquisition of Unilab's 
laboratories in Denver, Dallas, and Phoenix. With the completion of these 
transactions, MetPath is strategically positioned with efficient low-cost 
operations throughout the United States. 

MetPath's sales increased in both 1993 and 1992. Approximately 75% of the 
1993 sales growth resulted from Damon and other acquisitions. Excluding the 
impact of non-recurring charges, MetPath's 1993 earnings were up slightly due 
to the acquisition of Damon. Earnings growth in 1993 was hindered by 
competitive pricing pressures and an increasingly higher mix of business from 
lower-priced managed-care clients. MetPath recorded a $58.5 million 
restructuring charge in 1993 primarily for costs of closing MetPath 
facilities as a result of the integration of Damon and MetPath operations. 
This integration should provide MetPath with significant synergies and 
additional opportunities to reduce unit costs in 1994 and 1995. 

In September 1993, MetPath recorded a charge of $36.5 million to reflect the 
settlement and related legal expenses associated with its compromise 
agreement with the Civil Division of the Department of Justice to settle 
claims brought on behalf of the Inspector General, U.S. Department of Health 
and Human Services. The claims related to the marketing, sale, pricing and 
billing of certain blood-test series provided to Medicare patients. The 
settlement does not constitute an admission by MetPath with respect to any 
issue arising from the civil action. In the third quarter 1993, MetPath, 
along with other major clinical laboratories, received subpoenas for 
additional information relating to certain other tests. In addition, certain 
payors are reviewing their reimbursement practices for laboratory tests in 
response to announcements by certain competitors and continued pressure by 
government agencies. The outcome of these events is uncertain but could 
increase the current downward price trend in the clinical-testing industry. 
See "Business of Corning--Recent Developments--Department of Justice 
Investigation." 

Sales of the pharmaceutical services businesses have increased during the 
last three years. Earnings improved significantly in 1993 and 1992 primarily 
as a result of strong volume growth and cost-reduction actions. SciCor, Inc. 
("SciCor"), which was acquired in 1991, reported increased revenues and 
operating profits in both 1993 and 1992 as the market for clinical drug 
trials continues to grow. 

Sales at Enseco, the environmental-laboratory testing company, declined 
slightly in 1993 due to weak market conditions and a scale-back in 
operations. Sales in 1992 increased over 1991 levels primarily due to a late 
1991 acquisition. Earnings increased slightly in both 1993 and 1992 resulting 
from improved operating efficiencies and cost-reduction programs.

In November 1993, MetPath acquired 100% of certain Unilab facilities in 
exchange for a majority of the Unilab shares owned by MetPath, the assumption 
of approximately $70 million of Unilab debt, and MetPath's investment in J.S. 
Pathology PLC. MetPath retained a 12% equity investment in Unilab. At year 
end 1992, MetPath owned 43% of Unilab and, in contemplation of this 
transaction, accounted for it using the cost method of accounting for 
investments in 1993. 

Outlook: 

Sales of the Laboratory Services segment are expected to increase as a result 
of the Damon acquisition and volume gains in all businesses. MetPath's 
earnings are expected to increase as a result of significant cost reductions 
over the next year and synergies from the Damon acquisition offset somewhat 
by the continuing price pressures in the health care industry. Solid growth 
is expected to continue in the pharmaceutical services businesses. The 
environmental-laboratory testing business will continue to emphasize cost 
efficiencies and quality.

FAS 106 which totaled $6.3 million in 1992. 
(3) Includes $46.5 million and $63.3 million of restructuring charges in 1993 
and 1992, respectively. 

Consolidated operations: 

Consolidated sales in the Consumer Products segment declined in 1993 in 
comparison with 1992 due to the impact of a poor worldwide retail sales 
environment and the recent exit from the Brazilian market. Profitability has 
been affected by increased promotion costs, reduced manufacturing to realign 
inventory levels with lower sales volumes and reserves for certain inventory 
and product claims. Segment profits were also adversely impacted in 1993 by 
restructuring charges. Sales in 1992 were up in comparison with 1991; 
however, earnings in 1992 were down primarily due to a restructuring 
provision for the shutdown of operations in Brazil. 

In December 1993, Corning and Vitro of Mexico agreed to end their cross 
ownership of Corning Vitro in the United States and Vitro Corning in Mexico. 
As a result of the agreement, in December 1993, Vitro purchased the shares of 
capital stock of Vitro Corning owned by Corning and, in February 1994, 
Corning purchased the shares of capital stock of Corning Vitro held by Vitro. 
The net cost to Corning was $131 million. As a result of the transactions, 
Corning Vitro has changed its name to Corning Consumer Products Company. 
Corning and Vitro will continue their consumer products alliance through 
cross distribution and supply agreements. 

Corning Consumer Products' sales decreased in the North American and European 
markets in 1993. The decline in the U.S. market was attributable primarily to 
trade inventory corrections and reduced promotional activity. European sales 
continue to be impacted by the weak economy. In 1992, sales increased in 
North America but declined in Europe. Sales improved in Asia-Pacific in both 
1993 and 1992. 

Sales of Corning Ware(R) cookware and Pyrex(R) ware improved in 1993 compared 
with 1992. These increases were offset, however, by declines in sales of 
Visions(R) ware, due partially to Corning Consumer Products' exit from 
Brazil. Sales of Corelle(R) dinnerware and Revere Ware(R) cookware declined 
slightly. Corelle(R) dinnerware volume was affected by trade inventory 
corrections and reduced trade promotional activity. 

Restructuring charges totaling $46.5 million in this segment included costs 
of a reduction in the salaried work force, the consolidation of Corning 
Ware(R) cookware and Visions(R) ware manufacturing, and the consolidation of 
North American packaging operations. 

Sales of Steuben(R) crystal increased over 1992 due to a general increase in 
volume as well as the opening of several new retail stores and wholesale 
galleries and new product introductions. Earnings of this business improved 
slightly in 1993 due to improved glass melting performance and quality 
initiatives.

Corning's share of net income (loss)      (15.7)     (5.4)    1.7 

Equity in earnings in 1993 continued to be negatively impacted by the poor 
operating results of Vitro Corning due to the combined impact of the weak 
Mexican economy, domestic Mexican inflation, increasing foreign competition 
in Mexico and the strength of the Mexican peso. Vitro Corning's 1993 
operating losses were offset somewhat by a favorable non-recurring tax 
adjustment. Corning also recorded a $9.5 million reduction in equity earnings 
resulting from a restructuring charge taken by Vitro Corning in 1993. The 
decline in 1992 was the result of equity losses recorded by Vitro Corning, 
due primarily to adverse retail market conditions in Mexico. 

Outlook: 

Sales and earnings are expected to improve in 1994 as the benefits of 
restructuring programs implemented in 1993 and a focused marketing strategy 
positively impact performance. The change from cross 

ownership to distribution and supply agreements with Vitro is expected to 
have a modest positive impact on earnings. Economic uncertainties, especially 
in Europe, will continue to impact this segment. 

  Other Revenues and Deductions 
Non-operating gains and losses: 

In 1993, Corning recognized a non-operating gain of $4.2 million ($2.6 
million after tax). 

In 1992, Corning recognized net non-operating gains from consolidated 
operations totaling $7.0 million ($21.7 million after tax), including a gain 
of $10.1 million (before and after tax) from the sale of an additional equity 
interest in Corning Japan K.K. and a pre-tax loss of $7.3 million ($9.0 
million after-tax gain) from the formation of the consumer housewares venture 
with Vitro. 

In 1991, Corning recognized net non-operating gains from consolidated 
operations totaling $8.1 million ($14.6 million after tax) which included a 
gain of $5.3 million (before and after tax) on the sale of an equity interest 
in Corning Japan. 

Provision for restructuring and other special charges: 

In 1993, Corning recorded a charge of $170.5 million ($98.5 million after tax 
of $64.6 million and minority interest of $7.4 million) as a result of costs 
to integrate the Damon and Costar acquisitions and as a result of a planned 
company-wide restructuring program to reduce assets and overhead costs during 
the next year. Also in 1993, MetPath recorded a charge of $36.5 million 
($22.0 million after tax) to reflect the settlement and related legal 
expenses associated with its compromise agreement with the Civil Division of 
the Department of Justice to settle claims brought on behalf of the Inspector 
General, U.S. Department of Health and Human Services. 

In 1992, Corning recorded a charge of $63.3 million ($32.1 million after tax 
of $22.9 million and minority interest of $8.3 million) as a result of 
Corning Vitro's decision to restructure its Brazilian operations. 

Equity earnings: 

In 1993, Corning recognized a $203.1 million reduction in equity earnings as 
a result of an accounting charge taken by Dow Corning related to 
breast-implant litigation and a $9.5 million reduction in equity earnings as 
a result of a restructuring charge taken by Vitro Corning. 

In 1992, Corning recognized a $37.7 million reduction in equity earnings 
which included $24.5 million of accounting charges associated with Dow 
Corning's terminated breast-implant business and $13.2 million of 
restructuring charges associated with Dow Corning's exit from its Brazilian 
operations and other cost-reduction programs. 

In 1991, Corning recognized an $8.2 million reduction in equity earnings to 
reflect an accounting charge recorded by Dow Corning for costs associated 
with its terminated breast-implant business. 

  Taxes 
Corning's effective tax rate varies between years due primarily to the impact 
of certain non-operating gains and losses and restructuring charges. The 
effective tax rates, excluding these items, were 31% in 1993, 33% in 1992, 
and 37% in 1991. The reduced 1993 rate is primarily due to tax benefits 
associated with the sale of the process systems business and the revaluation 
of deferred tax assets discussed below. The reduced 1992 rate resulted from 
the implementation of repatriation programs and increased utilization of tax 
credits. 

Corning adopted FAS 109 at the beginning of 1993. The impact of adoption of 
FAS 109 was not material. On August 10, 1993, the Revenue Reconciliation Act 
of 1993 (the "Act") was signed into law. The Act increased the U.S. corporate 
statutory tax rate from 34% to 35% for years beginning after December 31, 
1992, changed the deductibility of certain expenses and extended certain tax 
credits. The increase in the statutory tax rate resulted in a gain from the 
revaluation of Corning's net deferred tax assets in the third quarter 1993 
which lowered the 1993 effective tax rate. Excluding this gain, the impact of 
the Act did not have a material impact on Corning's effective tax rate. 

  Liquidity and Capital Resources 
Corning's working capital of $451.4 million at the end of 1993 declined 
slightly from $465.2 million at the end of 1992. The ratio of current assets 
to current liabilities was 1.4 at the end of 1993 compared with 1.6 at the 
end of 1992. Corning's ratio of long-term debt to total capital increased to 
45% at the end of 1993 from 28% at the end of 1992. The change in the ratio 
of long-term debt to total capital is primarily due to the financing of the 
Damon acquisition. 

In 1993, Corning increased its available bank credit lines by $155 million. 
In addition, Corning borrowed $600 million under agreements with two banks to 
finance the acquisition of Damon for approximately $405 million in cash and 
the refinancing of approximately $167 million of Damon's debt. In September 
1993, Corning issued $200 million of long-term debt securities in public 
offerings and used the proceeds of such offerings to repay an equivalent 
amount of the acquisition debt. Corning intends to refinance a significant 
portion of the remaining acquisition debt with the net proceeds from this 
Offering. 

  Cash Flows 
Cash flows from operating activities increased in 1993 compared with 1992 
primarily due to a significant reduction in net current operating assets and 
liabilities (excluding the impact of acquisitions) offset by the payment by 
MetPath to the Department of Justice and the suspension of dividends from Dow 
Corning. Cash flows from operating activities increased in 1992 over 1991 
primarily due to improved operations. 

Cash used in investing activities increased significantly in 1993 over 1992 
primarily due to the acquisition of Damon for approximately $405 million. 
Cash used in investing activities also increased in 1992 over 1991 primarily 
due to increased investments in plant and equipment and acquisitions in the 
Laboratory Services segment, partially offset by the receipt of $137 million 
of net proceeds from the formation of Corning Vitro and Vitro Corning. 
Capital spending increased in 1993 when compared with 1992 primarily due to 
the expansion of the liquid-crystal display facility in Japan and the 
completion of Corning's corporate headquarters building. Capital spending 
increased in 1992 over 1991 primarily due to the continued expansion of the 
Wilmington, North Carolina, optical-fiber manufacturing facility, the 
construction of additional facilities to support growth in the Laboratory 
Services segment and the construction of the corporate headquarters building. 
At year end 1993, Corning's capital commitments totaled approximately $199.2 
million. 

In 1993, cash provided by financing activities increased significantly over 
1992 primarily as a result of increased borrowings to finance the acquisition 
of Damon and the telecommunications business of GTE Control Devices 
Incorporated and to finance continued capital expansion programs. In 1992, 
cash used in financing activities increased significantly over 1991 due to 
higher levels of common stock repurchases and the timing of dividend 
payments. 

Corning repurchased 1,323,700; 2,910,500; and 1,989,000 shares of its common 
stock in 1993, 1992, and 1991, respectively, pursuant to a systematic plan 
authorized by the Board of Directors. This activity is designed to provide 
shares for Corning's various employee-benefit programs. Corning suspended its 
share repurchase program in May 1993 to conserve cash for acquisition 
purposes. 

Dividends paid to common shareholders in 1993 totaled $134.1 million compared 
with $176.7 million in 1992 and $92.6 million in 1991. The higher 1992 
payment resulted from a $0.15 per-share special dividend declared in 1991 and 
paid in 1992 and the payment of the fourth quarter 1992 dividend prior to the 
end of fiscal 1992. Excluding these items, the increase in dividends paid was 
caused by an increase in the dividend rate of 10% and 17% in 1993 and 1992, 
respectively, and the increase in common shares outstanding. 

  Environment 
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 for 22 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 based on expert analysis and 
continual monitoring by both internal and external consultants. Corning has 
accrued for its estimated liability with respect to each of these sites and 
has not reduced the liability for any potential insurance recoveries. The 
aggregate liability is not material to the Company's operations or financial 
position. 

  Effects of Inflation 
Amounts reflected in the financial statements do not provide for the effect 
of inflation on operations or financial position. The expenses and asset 
values, specifically those related to long-lived assets, reflect historical 
cost and do not necessarily represent replacement cost or charges to 
operations based on replacement cost. Corning's operations are geared to 
provide funds from operations which would be sufficient along with other 
sources to replace fixed assets as necessary. Net income would be lower than 
reported if the effects of inflation were reflected by charging operations 
for replacement costs. 

BUSINESS OF CORNING 

General 
Corning traces its origin to a glass business established by the Houghton 
family in 1851. The present corporation was incorporated in the State of New 
York in December 1936, and its name was changed from Corning Glass Works to 
Corning Incorporated on April 28, 1989. 

Corning is an international corporation competing in four broadly-based 
business segments: Specialty Materials, Communications, Laboratory Services 
and Consumer Products. Corning is engaged principally in the manufacture and 
sale of products made from specialty glasses and related inorganic materials 
having special properties of chemical stability, electrical resistance, heat 
resistance, light transmission and mechanical strength. Corning and its 
subsidiaries annually produce some 60,000 different products at 44 plants in 
eight countries. In addition, Corning, through subsidiaries and affiliates, 
engages in laboratory services businesses, including life and environmental 
sciences and clinical-laboratory testing at 62 facilities in ten countries. 

Corning's strategy includes growth from new products developed from Corning's 
long-standing commitment to research and development and from mergers and 
acquisitions. Accordingly, Corning continuously reviews potential acquisition 
opportunities, primarily in the laboratory services and communications areas. 
However, there can be no assurance that Corning will pursue any such 
acquisition opportunity. 

In addition to the restructuring programs already under way, Corning is 
currently engaged in a comprehensive review of its business and cost 
structure. Corning expects this review to be substantially completed by the 
end of 1994. 

Specialty Materials 
Corning's Specialty Materials segment sells more than 40,000 products and has 
evolved from Corning's historical business base in materials development. The 
major business units within the Specialty Materials segment are: automotive 
substrates, ophthalmic and optical products, automotive lighting, science 
products, and other advanced materials. Products manufactured by these 
businesses include cellular ceramics for automotive and stationary 
emission-control devices, plastic and glass ware for laboratory applications 
and glass optical lenses. 

Corning's long standing commitment to research, development and engineering 
has driven the introduction of new products and technologies. In the 1970's 
Corning developed the technology and created products for the substrates used 
in emission control systems. Today the environmental products business 
continues to be a driving force within the Specialty Materials segment. 
Corning continues to develop new products and technologies to meet increasing 
demand as a result of tightened regulations in the United States and Europe 
and new regulations in other parts of the world. For example, to meet 
tightening clean air standards, Corning has developed as a prototype an 
electrically heated automotive catalytic converter substrate that begins 
working within seconds of ignition, which is when most of the pollutants are 
generated. Corning has developed a new family of materials, glass-polymers, 
the properties of which make them well suited for components in automobiles, 
aircraft, lighting systems and electronic devices. 

Corning's equity company investments in this segment include Dow Corning, 
Pittsburgh Corning and Cormetech, Inc., an equity company which manufactures 
and sells stationary emission control devices for power plants. 

Communications 
Corning's Communications segment consists of the following major product 
lines: optical fiber, optical cable, optical components, liquid-crystal 
display glass, television bulbs, lenses for projection television, and 
magnetic memory disks. 

Corning's Communications segment also originates from Corning's commitment to 
research and development in new materials. Corning led the development of the 
modern opto-electronics market with its invention of optical fiber in the 
late 1960's and is the leading supplier of optical fiber and such supporting 
components as couplers and signal splitters. Corning is also a leading 
supplier of optical cable through its 50% ownership of Siecor. In addition, 
Corning has several equity investments in companies that produce optical 
fiber internationally. 

Approximately two-thirds of the revenues in the Communications segment are 
generated by sales of opto-electronic products. Today, optical fiber is 
penetrating the communications market as optical fiber 

is rapidly becoming the preferred way to transmit telephone, cable-TV and 
computer data worldwide. Optical fiber permits the transmission of 
substantially more data over greater distances with less distortion than does 
copper, the product it is principally replacing. As users of optical fiber 
increase applications and expand services, Corning continues to provide new 
and improved optical-fiber products and corollary components to an expanding 
market. During the next few years, management believes that more fiber will 
be deployed in distribution cables and that utilization of fiber to the home 
will increase. 

Corning continues to be a leading producer of glass panels and funnels for 
television picture tubes through Corning Asahi Video Products Company, and is 
also a world leader in the production of projection television lenses through 
its wholly owned subsidiary, U.S. Precision Lens Inc. 

The market for liquid-crystal display glass continues to grow, currently 
driven by notebook computer and portable-TV sales. Future applications are 
expected to include desktop-computer displays, projection-TV systems, video 
phones and automotive applications. Corning is the world's leading supplier 
in this market. 

Another Corning invention, the MemCor(tm) glass-ceramic memory disk for 
high-performance hard-disk drives in computers, significantly increases 
storage capacity and improves reliability. 

Also included in this segment is Biosym, which develops and markets 
computer-aided molecular design software. 

Laboratory Services 
Corning entered the laboratory services market in the early 1970's with its 
initial investment in MetPath, a regional U.S. clinical laboratory which 
Corning acquired in 1982. Since 1982, Corning has made several other 
acquisitions in the clinical, biological, pharmaceutical and 
environmental-services industries. In 1991 Corning combined its 
laboratory-service business units into a wholly owned subsidiary, Corning Lab 
Services Inc. ("CLSI"), to better manage the development of its business in 
this rapidly growing area. Today CLSI operates 62 facilities in ten countries 
that provide clinical, pharmaceutical and environmental testing services. 

CLSI's clinical testing subsidiary, MetPath, performs more than 1,400 
different clinical tests for physicians, hospitals, laboratories, industries, 
health-maintenance organizations and other managed-care providers through a 
quick-response network of regional U.S. laboratories. MetPath is a leader in 
providing cost-effective and reliable clinical diagnostic testing services. 
See "--Recent Developments--Department of Justice Investigation." 

In August 1993 Corning acquired all of the outstanding shares of common stock 
of Damon in a transaction accounted for as a purchase. The total purchase 
price of this transaction was approximately $405 million, including 
acquisition expenses. In addition, approximately $167 million of indebtedness 
of Damon has been refinanced. Corning has financed the acquisition of Damon 
and the refinancing of Damon's debt with financing agreements entered into 
with certain commercial banks. Approximately $200 million of such financing 
has been retired with the proceeds from the issuance of long-term debt of 
Corning. Corning intends to retire a significant portion of the remaining 
acquisition debt with the net proceeds of the Offering. 

Damon's principal line of business is clinical-laboratory testing, providing 
to the medical profession a full range of routine and esoteric testing 
services that are used in the diagnosis, monitoring and treatment of disease. 
Damon provides its services to physicians, hospitals, nursing homes, managed 
care institutions, corporations and governmental agencies, including agencies 
of the United States of America. 

On May 4, 1994, Corning signed a definitive agreement to acquire all of the 
outstanding shares of Maryland Medical and several affiliates for 
approximately 4.5 million shares of Corning Common Stock in a pooling of 
interests transaction. The transaction, which is subject to regulatory 
approval, is expected to close in the second or third quarter 1994. 

CLSI's pharmaceutical-testing businesses are conducted by MetPath's wholly 
owned subsidiaries, G.H. Besselaar Associates, Hazelton Corporation and 
SciCor. These businesses perform chemical and biological testing, clinical 
research and data management services primarily for the pharmaceutical 
industry. Corning's environmental-laboratory testing business is conducted by 
MetPath's Enseco division and provides tests for environmental contaminants 
in soil, water and air for industry and government. 

On May 2, 1994, Corning and International Technology signed a definitive 
agreement to create a jointly owned company to provide environmental testing 
and related services. Under the terms of the 

agreement, Corning will transfer the net assets of its environmental testing 
laboratory business to the new company and International Technology will 
transfer the assets of its IT Analytical Services business to the new 
company. Corning and International Technology each will own 50 percent of the 
company. The transaction, which is subject to regulatory approval, is 
expected to close in the second or third quarter 1994. See "--Recent 
Developments--Creation of Environmental Testing Services Company." 

Corning's Laboratory Services segment is being affected by new federal 
legislation implemented in January 1994. The new legislation reduces Medicare 
reimbursement rates and will limit future laboratory fee increases. In 
addition, the Clinton Administration's health-care plan calls for managed 
competition with limitations on total national health-care expenditures and 
on the annual growth of such expenditures. A health-care reform model based 
on managed competition will likely reduce reimbursements for clinical 
laboratory services as managed care networks continue to proliferate. As the 
plan also calls for insurance coverage for some 37 million people who 
currently have no such coverage, it is expected that demand for such services 
will increase. Demand should also increase as a result of a stronger emphasis 
on testing as a preventative measure. It is not clear how quickly or to what 
extent Medicare and Medicaid programs will be incorporated into the health 
reform system. Management believes that while the entire health-care industry 
faces dramatic challenges to build a more effective means of delivery of 
services, MetPath's leading market position in major geographic areas will 
allow Corning to continue to benefit from the ongoing and increasing 
consolidation in the industry. 

Consumer Products 
Corning is well known for its line of consumer housewares with strong brand 
names and consumer franchise. Key product lines are Pyrex(R) glassware, 
Corelle(R) tableware, Corning Ware(R), Visions(R) cookware, and Revere 
Ware(R) cookware. Other Corning consumer products include the prestigious 
Steuben(R) crystal and Serengeti(R) sunglasses. 

Corning's executive offices are located at One Riverfront Plaza, Corning, New 
York 14831, and its telephone number at such offices is (607) 974-9000. 

Recent Developments 
Disposition of Clinical Laboratory Testing Operations. On April 4, 1994, 
MetPath sold the clinical laboratory testing operations of Damon in 
California for approximately $51 million in cash. No gain or loss will be 
recognized as a result of this transaction. The proceeds from the transaction 
will be used to retire a portion of the debt incurred in connection with the 
acquisition of Damon in August 1993. 

Creation of Environmental Testing Services Company. On May 2, 1994, Corning 
and International Technology signed a definitive agreement to create a 
jointly owned company to provide environmental testing and related services. 
Under terms of the agreement, Corning will transfer the net assets of its 
environmental testing laboratory business to the new company and 
International Technology will transfer the assets of its IT Analytical 
Services business to the new company. Corning and International Technology 
each will own 50 percent of the company. The transaction, which is subject to 
regulatory approval, is expected to close in the second or third quarter 
1994. Corning will account for its investment in the newly created company 
using the equity method of accounting for investments. The impact of the 
transaction is not expected to be material to Corning's financial statements. 

Acquisition of Maryland Medical. On May 4, 1994, Corning signed a definitive 
agreement to acquire all of the outstanding shares of Maryland Medical for 
approximately 4.5 million shares of Corning Common Stock in a pooling of 
interests transaction. The transaction, which is subject to regulatory 
approval, is expected to close in the second or third quarter 1994. The 
impact of the transaction is not expected to be material to Corning's 
financial statements. 

Sale of Parkersburg Plant. On May 23, 1994, Corning sold its Parkersburg, 
West Virginia, glass-tubing products plant to Schott Scientific Glass, Inc., 
a subsidiary of Schott Corporation, for $57 million. The transaction is 
expected to result in a modest after-tax gain. 

Breast Implant Litigation. Corning continues to be a defendant in two types 
of cases previously reported involving the silicone-gel breast implant 
products or materials formerly manufactured or supplied by Dow Corning or a 
Dow Corning subsidiary. These cases include (1) several purported federal 
securities class action lawsuits and shareholder derivative lawsuits filed 
against Corning by shareholders of Corning alleging, among other things, 
misrepresentations and omissions of material facts, breach of duty to 
shareholders and waste of corporate assets relative to the silicone-gel 
breast implant business conducted by Dow Corning and (2) as of May 23, 1994 
over 3,490 lawsuits filed in various state courts against Corning 

and others (including Dow Corning) by persons claiming injury from the 
silicone-gel breast implant products or materials formerly manufactured by 
Dow Corning or a Dow Corning subsidiary. Several of such suits have been 
styled as class actions and others involve multiple plaintiffs. 

All of the more than 3,000 tort lawsuits filed against Corning in federal 
courts were consolidated in the United States District Court, Northern 
District of Alabama, and in early December 1993, Corning was dismissed from 
these cases. This decision by the District Court is non-appealable and, 
although the District Court noted that it was "highly unlikely" that 
additional discovery would produce new evidence, the decision is subject to 
reconsideration if additional information is discovered or if there is a 
change in state law. Certain state court tort cases against Corning have also 
been consolidated for the purposes of discovery and pretrial matters. During 
1994, Corning has made several motions for summary judgment in state courts 
and judges have dismissed Corning from all of the over 2,500 tort cases filed 
in California, Michigan, New York and Pennsylvania. Corning's motions seeking 
dismissal remain pending in various other states. The federal securities 
suits are all pending in the United States District Court for the Southern 
District of New York. 

Corning's management does not believe that the purported securities class 
action lawsuits or the purported shareholder derivative lawsuits or the tort 
actions filed against Corning described above will have a material adverse 
effect on Corning's financial condition or the results of its operations. 

Dow Corning has informed Corning that as of April 15, 1994, Dow Corning has 
been named in 45 purported breast implant product liability class action 
lawsuits and approximately 14,500 individual breast implant product liability 
lawsuits (which number includes all or substantially all of the 3,490 
lawsuits referred to above) and that Dow Corning anticipates that it will be 
named as a defendant in additional breast implant lawsuits in the future. Dow 
Corning has also stated that it is vigorously defending this litigation. 

Verdicts in breast implant litigation against Dow Corning and other 
defendants which have gone to judgment have varied widely, ranging from 
dismissal to the award of significant compensatory and punitive damages. 

Dow Corning has also informed Corning that Dow Corning believes that a 
substantial portion of the indemnity and defense costs related to the breast 
implant litigation brought and to be brought against it is and will be 
covered by product liability insurance available to it but that the insurance 
companies issuing the policies in question have reserved the right to deny 
coverage under various theories and in many cases have refused to pay defense 
and indemnity costs which have been incurred by Dow Corning. In this regard, 
on June 30, 1993, Dow Corning instituted litigation in California against 
certain insurance companies which had issued product liability insurance 
policies to it from 1962 through 1985 seeking declaratory judgments that the 
insurance company defendants are liable to indemnify Dow Corning for such 
liabilities and costs and, in the case of certain insurance company 
defendants, damages including punitive damages. In September 1993, several of 
Dow Corning's insurers filed a complaint against Dow Corning and other 
insurers for declaratory relief in Michigan and moved for the action brought 
by Dow Corning in California to be dismissed in favor of the Michigan 
litigation. In October 1993, this motion was granted. In March 1994, the 
Michigan court ruled that certain of Dow Corning's primary insurers had a 
duty to defend Dow Corning with respect to certain breast implant product 
liability lawsuits. These insurers were directed to reimburse Dow Corning for 
certain defense costs previously incurred. Dow Corning has informed Corning 
that it is continuing negotiations with such insurance companies to obtain an 
agreement on a formula for the allocation among these insurers of payments of 
defense and indemnity expenses related to breast implant products liability 
lawsuits and claims. 

In March 1994, Dow Corning, along with other defendants and representatives 
of breast implant litigation plaintiffs, signed a Breast Implant Litigation 
Settlement Agreement (the "Settlement Agreement"). Under the Settlement 
Agreement and related agreements, industry participants (the "Funding 
Participants") would contribute approximately $4.2 billion over a period of 
more than thirty years to establish several special purpose funds. The 
Settlement Agreement, if implemented, would provide for a claims based 
structured resolution of claims arising out of silicone breast implants, 
define the circumstances under which payments from the funds would be made 
and include a number of other provisions related to claims and 
administration. The Settlement Agreement defines periods during which breast 
implant plaintiffs may elect not to settle their claims by way of the 
Settlement Agreement and to continue their individual breast implant 
litigation against manufacturers and other defendants (the "Opt Out 
Plaintiffs"). In certain circumstances, if Dow Corning considers the number 
of Opt Out Plaintiffs to be excessive, Dow Corning is entitled to withdraw 
from participation in the Settlement Agreement. Corning would not be required 
to make any contribution to the funds established under the Settlement 
Agreement. 

In April 1994, the U.S. District Court for the Northern District of Alabama 
preliminarily approved the Settlement Agreement and temporarily stayed and 
suspended federal and state class action certification or notice proceedings 
relative to federal or state class action lawsuits filed by plaintiffs 
included in the settlement class. 

In April 1994, the Court also notified the breast implant plaintiffs eligible 
to participate in the settlement of a 60-day period during which they have 
the ability to become initial Opt Out Plaintiffs. A Court-supervised fairness 
review process of the Settlement Agreement must be completed before the 
Settlement Agreement can be implemented. Once the Settlement Agreement is 
approved by the Court, claims can then be validated. The Court's approval of 
the Settlement Agreement would be subject to appeal. 

Dow Corning recorded a pre-tax charge of $640 million ($415 million after 
tax) against its earnings for the fourth quarter of 1993 to reflect its best 
estimate as of January 1994 of the net present value of its net liabilities 
and costs as a result of its involvement in breast implant litigation and, as 
a result of Dow Corning's decision to take this charge, Corning recorded a 
charge of $203 million after tax against its equity in earnings of associated 
companies for the fourth quarter of 1993 and against the carrying value of 
its investment in Dow Corning at the end of fiscal 1993. 

If the tort actions filed against Dow Corning or any settlement of the breast 
implant controversy should require Dow Corning to record any additional 
charges against income, the effect on Corning of any such additional charges 
would be limited to their consequent impact (in the amount of approximately 
50% of the amount thereof) on Corning's reported equity in earnings of 
associated companies for the period such charges were recognized, on the book 
value of Corning's equity investment in Dow Corning and on Corning's retained 
earnings. Corning does not believe that its share of any additional charges 
taken by Dow Corning resulting from the breast implant controversy will have 
a material adverse effect upon Corning's financial condition. However, it is 
possible that Corning's shares of any such additional charges taken by Dow 
Corning could have a material adverse effect upon Corning's earnings in the 
quarters in which any such charges were recognized by Dow Corning. 

Other Dow Corning Matters. Dow Corning received a request dated July 9, 1993 
from the Boston Regional Office of the Commission for certain documents and 
information related to silicone breast implants. The request stated that the 
Boston Regional Office was conducting an informal investigation which 
"concerns Dow Corning, its subsidiary Dow Corning Wright and parent 
corporations, Dow Chemical Co. and Corning Inc." Dow Corning has informed 
Corning that Dow Corning has responded to this request enclosing the 
documents and information requested along with related information and 
continues to cooperate with the Boston Regional Office. 

During the first quarter of 1993, Dow Corning received two federal grand jury 
subpoenas initiated by the United States Department of Justice ("DOJ") 
seeking documents and information related to silicone breast implants. Dow 
Corning has informed Corning that it has delivered the documents and 
information requested and continues to cooperate with the DOJ as this grand 
jury investigation proceeds. 

Department of Justice Investigation. In September 1993, MetPath and MetWest 
Inc. ("MetWest"), a wholly owned subsidiary of Unilab, in which Corning had 
at the time an interest of approximately 43%, entered into a Settlement 
Agreement (the "MetPath Settlement Agreement") with the DOJ and the Inspector 
General of the Department of Health and Human Services (the "Inspector 
General"). Pursuant to the MetPath Settlement Agreement, MetPath and MetWest 
paid to the United States a total of $39.8 million in settlement of civil 
claims by the DOJ and the Inspector General that MetPath and MetWest had 
wrongfully induced physicians to order certain laboratory tests without 
realizing that such tests would be billed to Medicare at rates higher than 
those the physicians believed were applicable. 

Several state and private insurers have made claims based on the practices 
covered by the MetPath Settlement Agreement. Several have settled but it is 
not clear at this time what, if any, additional exposure Corning may have to 
these entities and to other persons who may assert claims on the basis of 
these or other practices. 

During August 1993, MetPath, MetWest and Damon (which was acquired by Corning 
in that month) together with other participants in the industry received 
subpoenas from the Inspector General seeking information regarding their 
practices with respect to 14 enumerated tests offered in conjunction with 
automatic chemical test panels. Of these 14 tests, 5 were covered by the 
MetPath Settlement Agreement and consequently MetPath and MetWest are not 
being required to provide further information with regard to them. MetPath, 
MetWest and Damon have completed this process of complying with these 
subpoenas. 

The results of these investigations cannot currently be predicted but the 
possibility that they may result in additional claims by the DOJ or the 
Inspector General or additional claims or settlements with parties other than 
the DOJ and the Inspector General cannot be excluded. 

Other Legal Proceedings. During September 1993, two individuals filed in the 
Supreme Court of the State of New York (one in New York County and one in 
Suffolk County) separate purported derivative actions against Corning, as 
nominal defendant, and Corning's Directors and certain of its officers 
seeking on behalf of Corning compensatory and punitive damages in unspecified 
amounts (and plaintiffs' costs and disbursements including attorneys' and 
experts' fees) by reason of the alleged responsibility of the actual 
defendants for the conduct which gave rise to the settlement in the MetPath 
litigation described above and their alleged failure to cause Corning to make 
timely disclosure thereof. The parties have agreed to consolidate such 
actions in a single action before the Supreme Court of the State of New York 
in New York County. 

During October 1993, two individuals instituted in the United States District 
Court for the Southern District of New York separate purported class actions 
on behalf of purchasers of Corning securities in the open market during the 
period from September 17 to October 6, 1993 against Corning, certain of its 
Directors and officers and the underwriters of Corning's offering, on 
September 17, 1993, of $100 million of 6.75% Debentures due on September 15, 
2013. The complaints generally allege that the defendants failed to make 
timely disclosures of adverse developments in Corning's business and seek 
compensatory and punitive damages in unspecified amounts (and plaintiffs' 
costs and expenses including attorneys' fees and disbursements). These two 
actions have been consolidated. 

Two class actions have been filed in the Court of Chancery for the State of 
Delaware against Damon and certain of its officers and directors. These suits 
allege damages arising from Damon's failure to mention in the press release 
that announced the initial merger agreement it had reached with a company 
other than Corning that an unnamed bidder (Corning) had also expressed 
interest in acquiring Damon. The class of plaintiffs are those who sold their 
stock at the price offered by the other company, rather than the higher 
amount later offered and paid by Corning. 

Corning's management does not believe that the purported class action 
lawsuits or the purported shareholder derivative lawsuits described above 
will have a material adverse effect on Corning's financial condition or the 
results of its operations. 

                               CORNING DELAWARE 

Corning Delaware is a special purpose limited partnership formed under the 
laws of the State of Delaware. All of its partnership interests (other than 
the Preferred Securities) are and will be beneficially owned directly or 
indirectly by Corning. Corning is the sole general partner in Corning 
Delaware. Corning Finance Corporation, a Delaware corporation and a 
wholly-owned subsidiary of Corning ("Corning Finance"), initially will be the 
sole limited partner in Corning Delaware. Upon issuance of the Preferred 
Securities, which securities represent limited partnership interests in 
Corning Delaware, the holders of such Preferred Securities will become 
limited partners in Corning Delaware and Corning Finance will withdraw as a 
limited partner. The General Partner will agree to contribute capital to the 
extent required to maintain its capital at 21% of all capital in Corning 
Delaware. Corning Delaware will exist for a maximum term of 45 years, unless 
earlier dissolved. The Amended and Restated Limited Partnership Agreement of 
Corning Delaware (the "Limited Partnership Agreement") provides that the 
General Partner will have liability for the debts and obligations of Corning 
Delaware (including tax obligations as provided herein, but excluding 
obligations to holders of Preferred Securities in their capacities as 
holders, such obligations being separately guaranteed pursuant to the 
Guarantee). Under Delaware law, limited partners in a Delaware limited 
partnership (i.e., holders of the Preferred Securities) will not be liable 
for the debts, obligations and liabilities of such limited partnership, 
whether arising in contract, tort or otherwise, solely by reason of being a 
limited partner of Corning Delaware (subject to any obligation such holders 
have to repay any funds that may have been wrongfully distributed to them). 
All of Corning Delaware's business and affairs will be conducted by the 
General Partner. The location of the principal executive offices of the 
General Partner is One Riverfront Plaza, Corning, New York 14831, telephone 
number (607) 974-9000. Corning Delaware exists for the purpose of issuing the 
Preferred Securities and investing the proceeds thereof, together with 
substantially all of the capital contributed by the General Partner in the 
Subordinated Debentures. 

                      DESCRIPTION OF SECURITIES OFFERED 

The securities offered hereby are    % Convertible Monthly Income Preferred 
Securities of Corning Delaware with a liquidation preference of $50 per 
security. The Preferred Securities are convertible at the 

option of the holder into shares of Corning Common Stock at the rate of 
        shares of Corning Common Stock for each Preferred Security 
(equivalent to a conversion price of $        per share of Corning Common 
Stock), subject to adjustment in certain circumstances. The Preferred 
Securities are guaranteed, to the extent described herein, by Corning as to 
dividends, redemption proceeds and cash and other distributions payable on 
liquidation. In certain circumstances the holders can cause Corning Delaware 
to exchange all of the Subordinated Debentures for shares of Corning Series C 
Preferred Stock and distribute such shares in exchange for the Preferred 
Securities. 

The following is a description of the principal terms of the Preferred 
Securities; the Corning Common Stock and the Corning Series C Preferred Stock 
into or for which the Preferred Securities may be converted or exchanged; the 
Guarantee pursuant to which Corning will guarantee, to the extent described 
therein, certain payments with respect to the Preferred Securities; and the 
Subordinated Debentures and the fiscal agency agreement pursuant to which the 
Subordinated Debentures will be issued (the "Fiscal Agency Agreement"). 

Preferred Securities 

The following summary of principal terms and provisions of the Preferred 
Securities does not purport to be complete and is subject to, and qualified 
in its entirety by reference to, the Limited PartnershipAgreement, a copy of 
which is filed as an exhibit to the Registration Statement of which this 
Prospectus is a part. 

General 

All of the partnership interests in Corning Delaware other than the Preferred 
Securities offered hereby are, and at all times while the Preferred 
Securities are outstanding will be, owned directly or indirectly by Corning. 
The Limited Partnership Agreement authorizes and creates the Preferred 
Securities, which represent limited partnership interests in Corning 
Delaware. The limited partnership interests represented by the Preferred 
Securities will have a preference with respect to cash distributions and 
amounts payable on liquidation and redemption over the General Partner's 
interest in Corning Delaware. The Limited Partnership Agreement does not 
permit the issuance of other limited partnership interests without the prior 
approval of holders of not less than 662/3% of the aggregate liquidation 
preference of the Preferred Securities then outstanding. 

  Dividends 
Dividends (as defined herein) will be payable when, as, and if declared by 
the General Partner, except as otherwise described below. The dividends 
payable on each Preferred Security will be fixed at a rate per annum of $ 
        or     % of the liquidation preference of $50. The amount of 
dividends payable for any period will be computed on the basis of twelve 
30-day months and a 360-day year and, for any period shorter than a full 
month, will be computed on the basis of the actual number of days elapsed in 
such period. Payment of dividends is limited to the funds held by Corning 
Delaware and legally available therefor. See "--Description of the 
Subordinated Debentures--Interest" and "--Description of the 
Guarantee--General." 

Dividends on the Preferred Securities must be paid on the dates payable to 
the extent that Corning Delaware has funds legally available for the payment 
of such dividends and cash on hand sufficient to permit such payments. It is 
anticipated that Corning Delaware's funds will be limited principally to 
payments received under the Subordinated Debentures in which Corning Delaware 
will invest the proceeds from this Offering. See "--Description of the 
Subordinated Debentures." 

Corning has the right under the Subordinated Debentures to extend, from time 
to time, the interest payment periods on the Subordinated Debentures for up 
to 60 months. Monthly dividends on the Preferred Securities would be deferred 
(but would continue to compound interest monthly) by Corning Delaware during 
any such extended interest payment period. See "--Description of the 
Subordinated Debentures--Interest" and "--Option to Extend Interest Payment 
Period." The failure of holders to receive dividends in full for 15 
consecutive months would trigger the right of holders of a majority of the 
aggregate liquidation preference of the Preferred Securities then outstanding 
to cause Corning Delaware to exchange all of the Subordinated Debentures for 
shares of Corning Series C Preferred Stock at the Exchange Price and to 
distribute such shares to the holders of Preferred Securities in exchange for 
all of the Preferred Securities then outstanding. "Exchange Price" means one 
share of Corning Series C Preferred Stock for each $100 principal amount of 
Subordinated Debentures (which rate of exchange is equivalent to two 
Preferred Securities for one share of Corning Series C Preferred Stock). See 
"--Optional Exchange for Corning Series C Preferred Stock." 

Three months after the date of notice (the "Notice Date") of a Tax Event 
distributed by the General Partner to the holders of Preferred Securities or, 
if earlier, the date of a vote at any special partnership meeting (the 
"Meeting Date") called by the holders of the Preferred Securities to cause 
the exchange of all Preferred Securities for shares of Corning Series C 
Preferred Stock, all dividends and distributions by Corning Delaware 
(including distributions to the General Partner) shall be reduced by 
Additional Taxes. See "--Optional Exchange for Corning Series C Preferred 
Stock." 

"Tax Event" means that Corning shall have obtained an opinion of nationally 
recognized independent tax counsel experienced in such matters to the effect 
that, as a result of (a) any amendment to, or change (including any announced 
prospective change) in, the laws (or any regulations thereunder) of the 
United States or any political subdivision or taxing authority thereof or 
therein, (b) any amendment to, or change in, an interpretation or application 
of any such laws or regulations by any legislative body, court, governmental 
agency or regulatory authority (including the enactment of any legislation 
and the publication of any judicial decision or regulatory determination on 
or after such date), (c) any interpretation or pronouncement that provides 
for a position with respect to such laws or regulations that differs from the 
generally accepted position or (d) any action taken by any governmental 
agency or regulatory authority, which amendment or change is enacted, 
promulgated, issued or effective or which interpretation or pronouncement is 
issued or announced or which action is taken, in each case above on or after 
the date of this Prospectus, there is more than an insubstantial risk that 
(i) Corning Delaware is subject to federal income tax with respect to 
interest accrued or received on the Subordinated Debentures, (ii) interest 
payable to Corning Delaware on the Subordinated Debentures will not be 
deductible for federal income tax purposes or (iii) Corning Delaware is 
subject to more than a de minimis amount of taxes, duties or other 
governmental charges. 

"Additional Taxes" means the sum of any additional income taxes, duties and 
other governmental charges to which Corning Delaware has become subject from 
time to time as a result of a Tax Event described in the preceding clauses 
(i) and (iii), except for U.S. withholding taxes. 

Corning will agree as General Partner in the Limited Partnership Agreement to 
pay any and all Additional Taxes, liabilities, costs and expenses with 
respect to such Additional Taxes of Corning Delaware for the period from the 
formation of Corning Delaware through the earlier of the Notice Date and the 
Meeting Date. 

Dividends declared on the Preferred Securities will be payable to the holders 
thereof as they appear on the books and records of Corning Delaware on the 
relevant record dates, which will be one Business Day (as defined below) 
prior to the relevant payment dates. Subject to any applicable laws and 
regulations and the Limited Partnership Agreement, each such payment will be 
made as described under "--Book-Entry-Only Issuance--The Depository Trust 
Company" below. In the event that any date on which dividends are payable on 
the Preferred Securities is not a Business Day, then payment of the dividend 
payable on such date will be made on the next succeeding day that is a 
Business Day (and without any interest or other payment in respect of any 
such delay) except that, if such Business Day is in the next succeeding 
calendar year, such payment will be made on the immediately preceding 
Business Day, in each case with the same force and effect as if made on such 
date. A "Business Day" means any day other than a day on which banking 
institutions in The City of New York are authorized or obligated by law or 
executive order to close. 

Certain Restrictions on Corning Delaware 

If accumulated and unpaid dividends have not been paid in full on the 
Preferred Securities, Corning Delaware may not: 

  (i) pay, or declare and set aside for payment, any dividends on any other 
partnership interests; or 

  (ii) redeem, purchase, or otherwise acquire any other partnership 
interests; 
until, in each case, such time as all accumulated and unpaid dividends on all 
of the Preferred Securities shall have been paid in full for all dividend 
periods terminating on or prior to the date of such payment or the date of 
such redemption, purchase, or acquisition, as the case may be. 

If accumulated and unpaid dividends have been paid in full on the Preferred 
Securities for all prior whole dividend periods, then holders of Preferred 
Securities will not be entitled to receive or share in any dividends paid, 
declared or set aside for payment on any other partnership interest in 
Corning Delaware. 

Optional Redemption 

Corning Delaware may not redeem the Preferred Securities prior to      , 
1998. On and after such date, Corning Delaware at its option may redeem the 
Preferred Securities, in whole or in part, on not fewer than 30 nor more than 
60 days' prior notice, at any time or from time to time, during the 
twelve-month periods beginning on                  , 1998 in each of the 
following years at the redemption price indicated below, plus accumulated and 
unpaid dividends (the "Redemption Price"): 



 Date                                  Redemption Price 
                                          
        , 1998 
        , 1999 
        , 2000 
        , 2001 
        , 2002 
        , 2003 
        , 2004 and thereafter 

Corning Delaware may not redeem the Preferred Securities in part unless all 
accumulated and unpaid dividends have been paid in full on all Preferred 
Securities for all monthly dividend periods terminating on or prior to the 
date of redemption. 

In the event that fewer than all of the outstanding Preferred Securities are 
to be redeemed, the Preferred Securities to be redeemed will be selected by 
lot as described under "--Book-Entry-Only Issuance--The Depository Trust 
Company" below. 

Mandatory Redemption 

Upon repayment or prepayment by Corning of the Subordinated Debentures, the 
proceeds from such repayment or prepayment will be applied to redeem the 
allocable portion of the Preferred Securities at the applicable Redemption 
Price. 

Redemption Procedures 

Notice of any redemption of Preferred Securities (which notice will be 
irrevocable) will be given by Corning Delaware to Corning and each record 
holder of Preferred Securities that are being redeemed not fewer than 30 nor 
more than 60 days prior to the date fixed for redemption thereof. If Corning 
Delaware gives a notice of redemption, then, by 12:00 noon, New York time, on 
the redemption date, Corning will repay an aggregate principal amount of the 
Subordinated Debentures plus accrued and unpaid interest in an amount equal 
to the applicable Redemption Price for the Preferred Securities to be 
redeemed. Corning Delaware will irrevocably deposit such funds with The 
Depository Trust Company ("DTC") and give DTC irrevocable instructions and 
authority to pay the applicable Redemption Price to the holders of the 
Preferred Securities to be redeemed. See "--Book-Entry-Only Issuance--The 
Depository Trust Company." If notice of redemption has been given and funds 
deposited with DTC as required, then immediately prior to the close of 
business on the date of such deposit, all rights of holders of such Preferred 
Securities so called for redemption will cease, except the right of the 
holders to receive the Redemption Price, but without additional interest. In 
the event that any date fixed for redemption of Preferred Securities is not a 
Business Day, then payment of the Redemption Price payable on such date will 
be made on the next succeeding day that is a Business Day (and without any 
interest or other payment in respect of any such delay), except that, if such 
Business Day falls in the next calendar year, such payment will be made on 
the immediately preceding Business Day. In the event that payment of the 
Redemption Price is improperly withheld or refused and not paid by either 
Corning Delaware or Corning pursuant to the Guarantee described under 
"--Description of the Guarantee" below, dividends on such securities will 
continue to accumulate at the then applicable rate, from the original 
redemption date to the date that the Redemption Price is actually paid. 

Subject to the foregoing and applicable law (including, without limitation, 
U.S. federal securities laws), Corning or its subsidiaries or affiliates may 
at any time and from time to time purchase outstanding Preferred Securities 
by tender, in the open market or by private agreement. 

Conversion Rights 

General. The Preferred Securities will be convertible at any time, at the 
option of the holder thereof, through Corning Delaware into shares of Corning 
Common Stock at an initial conversion price of $       per share of Corning 
Common Stock (equivalent to a conversion rate of           shares of Corning 

Common Stock for each Preferred Security), subject to adjustment as described 
below. Upon receiving an irrevocable notice by a holder of a Preferred 
Security to exercise its conversion right, Corning Delaware, on behalf of 
such holder, will exercise its option to convert such holder's allocable 
portion of the Subordinated Debentures into Corning Common Stock and will 
distribute such shares of Corning Common Stock to such holder in exchange for 
a corresponding portion of such holder's Preferred Securities. Preferred 
Securities that have been called for redemption will not be convertible after 
the close of business two calendar days preceding the date fixed for 
redemption, unless Corning Delaware defaults in making payment of the amount 
payable upon such redemption date. Conversion rights will terminate upon the 
making of an Exchange Election referred to below under "--Optional Exchange 
for Corning Series C Preferred Stock" and upon the issuance of Corning Series 
C Preferred Stock pursuant to such Exchange Election. 

Holders of Preferred Securities at the close of business on a dividend 
payment record date will be entitled to receive the dividend payable on such 
securities on the corresponding dividend payment date notwithstanding the 
conversion of such Preferred Securities following such dividend payment 
record date and on or prior to such dividend payment date. Except as provided 
above, Corning Delaware and Corning will make no payment or allowance for 
accumulated and unpaid dividends, whether or not in arrears, on converted 
securities or for dividends on the shares of Corning Common Stock issued upon 
such conversion. Each conversion will be deemed to have been effected 
immediately prior to the close of business on the day on which notice was 
received by Corning Delaware. 

No fractional shares of Corning Common Stock will be issued as a result of 
conversion, but in lieu thereof, in the sole discretion of the General 
Partner, such fractional interest will either be (i) rounded up to the next 
whole share or (ii) paid in cash by Corning. 

Conversion Price Adjustments. The conversion price will be subject to 
adjustment in certain events including, without duplication: (i) the payment 
of dividends (and other distributions) payable in Corning Common Stock on any 
class of capital stock of Corning; (ii) the issuance to all holders of 
Corning Common Stock of rights or warrants entitling holders of such rights 
or warrants to subscribe for or purchase Corning Common Stock at less than 
the current market price; (iii) subdivisions and combinations of Corning 
Common Stock; (iv) the payment of dividends (and other distributions) to all 
holders of Corning Common Stock of evidence of indebtedness of Corning, 
securities or capital stock, cash, or assets (including securities, but 
excluding those rights, warrants, dividends, and distributions referred to in 
clause (ii) and dividends and distributions paid exclusively in cash); (v) 
the payment of dividends (and other distributions) on Corning Common Stock 
paid exclusively in cash, excluding (A) cash dividends that do not exceed the 
per share amount of the immediately preceding quarterly or semi-annual, as 
applicable, cash dividend (as adjusted to reflect any of the events referred 
to in clauses (i) through (vi) of this sentence), or (B) cash dividends if 
the per share amount thereof multiplied by four with respect to quarterly 
dividends and multiplied by two with respect to semi-annual dividends does 
not exceed 15% of the current market price of Corning Common Stock on the 
trading day immediately preceding the date of declaration of such dividend; 
and (vi) payment in respect of a tender or exchange offer (other than an 
odd-lot offer) by Corning or any subsidiary of Corning for Corning Common 
Stock in excess of 10% of the current market price of Corning Common Stock on 
the trading day next succeeding the last date tenders or exchanges may be 
made pursuant to such tender or exchange offer. 

If after the Distribution Date for the preferred share purchase rights (the 
"Rights") of Corning, as presently constituted or under any similar plan (see 
"Description of Corning Capital Stock--Preferred Share Purchase Rights"), 
converting holders of the Preferred Securities are not entitled to receive 
the Rights that would otherwise be attributable (but for the date of 
conversion) to the shares of Corning Common Stock received upon such 
conversion, then adjustment of the conversion price shall be made under 
clause (iv) of the preceding paragraph as if the Rights were then being 
distributed to the common stockholders. If such an adjustment is made and the 
Rights are later redeemed, invalidated, or terminated, then a corresponding 
reversing adjustment shall be made to the conversion price, on an equitable 
basis, to take account of such event. 

Corning from time to time may reduce the conversion price by any amount 
selected by Corning for any period of at least 20 days, in which case Corning 
shall give at least 15 days' notice of such reduction. Corning may, at its 
option, make such reductions in the conversion price, in addition to those 
set forth above, as the Board of Directors deems advisable to avoid or 
diminish any income tax to holders of Corning Common Stock resulting from any 
dividend or distribution of stock (or rights to acquire stock) or from any 
event treated as such for income tax purposes. 

In the event that Corning is a party to any transaction (including, without 
limitation, a merger, consolidation, sale of all or substantially all of 
Corning's assets, recapitalization or reclassification of Corning Common 
Stock or any compulsory share exchange (each of the foregoing being referred 
to as a "Transaction")), in each case (except in the case of a Common Stock 
Fundamental Change referred to below) as a result of which shares of Corning 
Common Stock shall be converted into the right to receive securities, cash, 
or other property, each Preferred Security shall thereafter be convertible 
into the kind and amount of securities, cash, and other property receivable 
upon the consummation of such Transaction by a holder of that number of 
shares of Corning Common Stock into which a Preferred Security was 
convertible immediately prior to such Transaction (but after giving effect to 
any adjustment discussed below relating to a Fundamental Change if such 
Transaction constitutes a Fundamental Change, and subject to funds being 
legally available for such purpose under applicable law at the time of such 
conversion). 

If any Fundamental Change occurs, then the conversion price in effect will be 
adjusted immediately after such Fundamental Change as described below. In 
addition, in the event of a Common Stock Fundamental Change (as defined), 
each Preferred Security shall be convertible solely into common stock of the 
kind received by holders of Corning Common Stock as a result of such Common 
Stock Fundamental Change. 

For purposes of calculating any adjustment to be made pursuant to the 
preceding paragraph in the event of a Fundamental Change, immediately after 
such Fundamental Change: 

  (i) in the case of a Non-Stock Fundamental Change (as defined below), the 
conversion price of the Preferred Security will thereupon become the lower of 
(A) the conversion price in effect immediately prior to such Non-Stock 
Fundamental Change, but after giving effect to any other prior adjustments, 
and (B) the result obtained by multiplying the greater of the Applicable 
Price (as defined below) or the then applicable Reference Market Price (as 
defined below) by a fraction of which the numerator will be $50 and the 
denominator will be the then current redemption price per Preferred Security 
(or, for periods prior to          , 1998, an amount per Preferred Security 
determined by the General Partner in its sole discretion); and 

  (ii) in the case of a Common Stock Fundamental Change, the conversion price 
of the Preferred Securities in effect immediately prior to such Common Stock 
Fundamental Change, but after giving effect to any other prior adjustments, 
will thereupon be adjusted by multiplying such conversion price by a fraction 
of which the numerator will be the Purchaser Stock Price (as defined below) 
and the denominator will be the Applicable Price; provided, however, that in 
the event of a Common Stock Fundamental Change in which (A) 100% of the value 
of the consideration received by a holder of Corning Common Stock is common 
stock of the successor, acquiror, or other third party (and cash, if any, is 
paid with respect to any fractional interests in such common stock resulting 
from such Common Stock Fundamental Change) and (B) all of the Corning Common 
Stock will have been exchanged for, converted into, or acquired for common 
stock (and cash with respect to fractional interests) of the successor, 
acquiror, or other third party, the conversion price of the Preferred 
Securities in effect immediately prior to such Common Stock Fundamental 
Change will thereupon be adjusted by multiplying such conversion price by a 
fraction of which the numerator will be one and the denominator will be the 
number of securities of common stock of the successor, acquiror, or other 
third party received by a holder of one share of Corning Common Stock as a 
result of such Common Stock Fundamental Change. 

In the absence of the Fundamental Change provisions in the case of a 
Transaction, each Preferred Security would become convertible into the 
securities, cash, or property receivable by a holder of the number of shares 
of Corning Common Stock into which such Preferred Security was convertible 
immediately before such Transaction. This change could substantially lessen 
or eliminate the value of the conversion privilege associated with the 
Preferred Securities. For example, if Corning were acquired in a cash merger, 
each Preferred Security would become convertible solely into cash (in an 
amount less than the liquidation preference if the per share merger 
consideration is lower than the then applicable conversion price) and would 
no longer be convertible into securities whose value would vary depending on 
the future prospects of the issuer and other factors. 

The foregoing conversion price adjustments are designed, in "Fundamental 
Change" transactions where all or substantially all the Corning Common Stock 
is converted into securities, cash, or property and not more than 50% of the 
value received by the holders of Corning Common Stock consists of stock 
listed or admitted for listing subject to notice of issuance on a national 
securities exchange or quoted on 

the National Market System of the National Association of Securities Dealers, 
Inc. (a "Non-Stock Fundamental Change," as defined below), to increase the 
securities, cash, or property into which each Preferred Security is 
convertible. 

In a Non-Stock Fundamental Change transaction where the initial value 
received per share of Corning Common Stock (measured as described in the 
definition of Applicable Price below) is lower than the then applicable 
conversion price of a Preferred Security but greater than or equal to the 
"Reference Market Price" (initially $       but subject to adjustment in 
certain events as described below), the conversion price will be adjusted as 
described above with the effect that each Preferred Security will (subject to 
the existence of legally available funds) be convertible into securities, 
cash, or property of the same type received by the holders of Corning Common 
Stock in the transaction but in an amount that would at the time of the 
transaction have had a value (measured by reference to the value determined 
as described in the definition of Applicable Price below) equal to the then 
current Redemption Price per Preferred Security (or, for periods prior to 
             , 1998, an amount per Preferred Security determined by the 
General Partner in its sole discretion). 

In a Non-Stock Fundamental Change transaction where the initial value 
received per share of Corning Common Stock (measured as described in the 
definition of Applicable Price) is lower than both the Applicable Conversion 
Price of a Preferred Security and the Reference Market Price, the conversion 
price will be adjusted as described above but calculated as though such 
initial value had been the Reference Market Price, with the effect that each 
Preferred Security will (subject to the existence of legally available funds) 
be convertible into securities, cash, or property in an amount that would at 
the time of the transaction have had a value (measured as aforesaid) equal to 
(a) such initial value divided by the Reference Market Price times (b) the 
then current Redemption Price per Preferred Security (or, for periods prior 
to           , 1998 an amount per Preferred Security determined by the 
General Partner in its sole discretion). 

In a Fundamental Change transaction where all or substantially all the 
Corning Common Stock is converted into securities, cash, or property and more 
than 50% of the value received by the holders of Corning Common Stock 
consists of listed or National Market System traded common stock (a "Common 
Stock Fundamental Change," as defined below), the foregoing adjustments are 
designed to provide in effect that (a) where Corning Common Stock is 
converted partly into such common stock and partly into other securities, 
cash, or property, each Preferred Security will be convertible solely into a 
number of shares of such common stock determined so that the initial value of 
such shares (measured as described in the definition of "Purchaser Stock 
Price" below) equals the value of the shares of Corning Common Stock into 
which such Preferred Security was convertible immediately before the 
transaction (measured as aforesaid) and (b) where Corning Common Stock is 
converted solely into such common stock, each Preferred Security will be 
convertible into the same number of shares of such common stock receivable by 
a holder of the number of shares of Corning Common Stock into which such 
Preferred Security was convertible immediately before such transaction. 

The term "Applicable Price" means (i) in the case of a Non-Stock Fundamental 
Change in which the holders of the Corning Common Stock receive only cash, 
the amount of cash received by the holder of one share of Corning Common 
Stock and (ii) in the event of any other Non-Stock Fundamental Change or any 
Common Stock Fundamental Change, the average of the Closing Prices for the 
Corning Common Stock during the ten trading days prior to and including the 
record date for the determination of the holders of Corning Common Stock 
entitled to receive such securities, cash, or other property in connection 
with such Non-Stock Fundamental Change or Common Stock Fundamental Change or, 
if there is no such record date, the date upon which the holders of the 
Corning Common Stock shall have the right to receive such securities, cash, 
or other property (such record date or distribution date being hereinafter 
referred to the "Entitlement Date"), in each case as adjusted in good faith 
by the Board of Directors of Corning to appropriately reflect any of the 
events referred to in clauses (i) through (vi) of the first paragraph of this 
subsection. 

The term "Closing Price" means on any day the reported last sales price on 
such day or in case no sale takes place on such day, the average of the 
reported closing bid and asked prices in each case on the New York Stock 
Exchange Composite Tape or, if the stock is not listed or admitted to trading 
on such Exchange, on the principal national securities exchange on which such 
stock is listed or admitted to trading or if not listed or admitted to 
trading on any national securities exchange, the average of the closing bid 
and asked prices as furnished by any New York Stock Exchange member firm, 
selected by the Board of Directors of Corning for that purpose. 

The term "Common Stock Fundamental Change" means any Fundamental Change in 
which more than 50% of the value (as determined in good faith by the Board of 
Directors of Corning) of the consideration received by holders of Corning 
Common Stock consists of common stock that for each of the ten consecutive 
trading days prior to the Entitlement Date has been admitted for listing or 
admitted for listing subject to notice of issuance on a national securities 
exchange or quoted on the National Market System of the National Association 
of Securities Dealers, Inc.; provided, however, that a Fundamental Change 
shall not be a Common Stock Fundamental Change unless either (i) Corning 
continues to exist after the occurrence of such Fundamental Change and the 
outstanding Preferred Securities continue to exist as outstanding Preferred 
Securities or (ii) not later than the occurrence of such Fundamental Change, 
the outstanding Preferred Securities are converted into or exchanged for 
shares of convertible preferred stock of an entity succeeding to the business 
of Corning, which convertible preferred stock has powers, preferences, and 
relative, participating, optional, or other rights, and qualifications, 
limitations, and restrictions, substantially similar to those of the 
Preferred Securities. 

The term "Fundamental Change" means the occurrence of any transaction or 
event in connection with a plan pursuant to which all or substantially all of 
the Corning Common Stock shall be exchanged for, converted into, acquired 
for, or constitute solely the right to receive securities, cash, or other 
property (whether by means of an exchange offer, liquidation, tender offer, 
consolidation, merger, combination, reclassification, recapitalization, or 
otherwise), provided, that, in the case of a plan involving more than one 
such transaction or event, for purposes of adjustment of the conversion 
price, such Fundamental Change shall be deemed to have occurred when 
substantially all of the Corning Common Stock shall be exchanged for, 
converted into, or acquired for or constitute solely the right to receive 
securities, cash, or other property, but the adjustment shall be based upon 
the highest weighted average per share consideration that a holder of Corning 
Common Stock could have received in such transaction or event as a result of 
which more than 50% of the Corning Common Stock shall have been exchanged 
for, converted into, or acquired for or constitute solely the right to 
receive securities, cash, or other property. 

The term "Non-Stock Fundamental Change" means any Fundamental Change other 
than a Common Stock Fundamental Change. 

The term "Purchaser Stock Price" means, with respect to any Common Stock 
Fundamental Change, the average of the Closing Prices for the common stock 
received in such Common Stock Fundamental Change for the ten consecutive 
trading days prior to and including the Entitlement Date, as adjusted in good 
faith by the Board of Directors of Corning to appropriately reflect any of 
the events referred to in clauses (i) through (vi) of the first paragraph of 
this subsection; provided, however, if no such Closing Prices exist, then the 
Purchaser Stock Price shall be set at a price determined in good faith by the 
Corning Board of Directors. 

The term "Reference Market Price" shall initially mean $       (which is an 
amount equal to 66-2/3% of the reported last sale price for the Corning 
Common Stock on the NYSE on            , 1994), and in the event of any 
adjustment to the conversion price other than as a result of a Non-Stock 
Fundamental Change, the Reference Market Price shall also be adjusted so that 
the ratio of the Reference Market Price to the conversion price after giving 
effect to any such adjustment shall always be the same as the ratio of $ 
to the initial conversion price of the Preferred Securities. 

No adjustment of the conversion price will be made upon the issuance of any 
shares of Corning Common Stock pursuant to any present or future plan 
providing for the reinvestment of dividends or interest payable on securities 
of Corning and the investment of additional optional amounts in shares of 
Corning Common Stock under any such plan, or the issuance of any shares of 
Corning Common Stock or options or rights to purchase such shares pursuant to 
any present or future employee benefit plan or program of Corning or pursuant 
to any option, warrant, right, or exercisable, exchangeable, or convertible 
security outstanding as of the date the Preferred Securities were first 
designated. There shall also be no adjustment of the conversion price in case 
of the issuance of any stock (or securities convertible into or exchangeable 
for stock) of Corning, except as specifically described above. If any action 
would require adjustment of the conversion price pursuant to more than one of 
the provisions described above, only one adjustment shall be made and such 
adjustment shall be the amount of adjustment that has the highest absolute 
value to holders of the Preferred Securities. No adjustment in the conversion 
price will be required unless such adjustment would require an increase or 
decrease of at least 1% of the conversion price, but any adjustment that 
would otherwise be required to be made shall be carried forward and taken 
into account in any subsequent adjustment. 

Optional Exchange for Corning Series C Preferred Stock 

Upon the occurrence of an Exchange Event (as defined below), the holders of a 
majority of the aggregate liquidation preference of Preferred Securities then 
outstanding, voting as a class or by written consent, may, at their option, 
cause Corning Delaware to exchange all of the Subordinated Debentures for 
shares of Corning Series C Preferred Stock at the Exchange Price and 
distribute such shares to the holders of Preferred Securities. 

The Corning Series C Preferred Stock issued upon any such exchange will have 
terms substantially identical to the terms of the Preferred Securities, 
except that, among other things, the Corning Series C Preferred Stock will 
have the right to elect two additional directors of Corning whenever 
dividends on the Corning Series C Preferred Stock are in arrears for 18 
months (including for this purpose any arrearage with respect to the 
Preferred Securities) and will not be subject to mandatory redemption. See 
"--Description of Corning Series C Preferred Stock." The terms of the Corning 
Series C Preferred Stock provide that all accumulated and unpaid dividends 
(including any Additional Interest) on the Preferred Securities that are not 
paid by Corning pursuant to the Guarantee shall be treated as accrued and 
unpaid dividends on the Corning Series C Preferred Stock. See "--Description 
of the Guarantee." 

The following events are "Exchange Events": 

  (a) The failure of holders of Preferred Securities to receive, for 15 
consecutive months, the full amount of dividend payments on the Preferred 
Securities; or 

  (b) The occurrence of a Tax Event. 

As soon as practicable, but in no event later than 30 days after the 
occurrence of an Exchange Event, the General Partner will convene a general 
meeting of the holders of Preferred Securities (an "Exchange Election 
Meeting") for the purpose of acting on the matter of whether to cause Corning 
Delaware to exchange the Subordinated Debentures for shares of Corning Series 
C Preferred Stock or, in the case of a Tax Event, to continue to hold the 
Preferred Securities. If the General Partner fails to convene such Exchange 
Election Meeting within such 30-day period, the holders of at least 10% of 
the outstanding Preferred Securities will be entitled to convene such 
Exchange Election Meeting. Upon the affirmative vote of the holders of 
Preferred Securities representing not less than a majority of the aggregate 
liquidation preference of the Preferred Securities then outstanding at an 
Exchange Election Meeting or, in the absence of such meeting, upon receipt by 
Corning Delaware of written consents signed by the holders of a majority of 
the aggregate liquidation preference of the outstanding Preferred Securities, 
an election to exchange all outstanding Preferred Securities on the basis 
described above (an "Exchange Election") will be deemed to have been made. In 
the case of certain Tax Events, Corning Delaware will continue to pay 
dividends on the Preferred Securities without adjustment for Additional Taxes 
until the earlier of (i) three months after the Notice Date and (ii) the 
Meeting Date. During such time, Corning will pay any and all Additional Taxes 
of Corning Delaware. 

Holders of Preferred Securities, by purchasing such Preferred Securities, 
will be deemed to have agreed to be bound by these optional exchange 
provisions in regard to the exchange of such Preferred Securities for Corning 
Series C Preferred Stock on the terms described above. 

Liquidation Rights 

In the event of any voluntary or involuntary liquidation, dissolution, or 
winding-up of Corning Delaware, the holders of Preferred Securities at the 
time outstanding will be entitled to receive a liquidation preference of $50 
per Preferred Security plus all accumulated and unpaid dividends (whether or 
not earned or declared) to the date of payment (the "Liquidation 
Distribution") out of the assets of Corning Delaware legally available for 
distribution to partners prior to any other distribution by Corning Delaware. 

If, upon any liquidation of Corning Delaware, the holders of Preferred 
Securities are paid in full the aggregate Liquidation Distribution to which 
they are entitled, then such holders will not be entitled to receive or share 
in any other assets of Corning Delaware thereafter available for distribution 
to any other holders of partnership interests in Corning Delaware. 

Pursuant to the Limited Partnership Agreement, Corning Delaware shall be 
dissolved and its affairs shall be wound up upon the earliest to occur of: 
(i) the expiration of the term of Corning Delaware; (ii) the retirement, 
resignation, expulsion, bankruptcy or dissolution of the General Partner or 
the occurrence of any other event under the Delaware Revised Uniform Limited 
Partnership Act whereby Corning ceases 

to be the General Partner, except for a merger or consolidation of Corning 
with or into, or the sale, transfer or lease of all or substantially all of 
Corning's assets to, a permitted successor General Partner under the Limited 
Partnership Agreement; (iii) upon the entry of a decree of a judicial 
dissolution; or (iv) upon the written consent of all partners of Corning 
Delaware. 

Merger, Consolidation or Sale of Assets of Corning Delaware 

The General Partner is authorized and directed to conduct its affairs and to 
operate Corning Delaware in such a way that Corning Delaware will not be 
deemed to be an "investment company" required to be registered under the 
Investment Company Act of 1940 (the "1940 Act") or taxed as a corporation for 
federal income tax purposes and so that the Subordinated Debentures will be 
treated as indebtedness of Corning for federal income tax purposes. In this 
connection, the General Partner is authorized to take any action not 
inconsistent with applicable law, the Certificate of Limited Partnership of 
Corning Delaware or the Limited Partnership Agreement that does not adversely 
affect the interests of the holders of the Preferred Securities and that the 
General Partner determines in its discretion to be necessary or desirable for 
such purposes. 

Corning Delaware may not consolidate, merge with or into, or be replaced by, 
or convey, transfer or lease its properties and assets substantially as an 
entirety to any entity, except as described below. Corning Delaware may, for 
purposes of changing its state of domicile in order to avoid federal income 
tax or 1940 Act consequences adverse to Corning or Corning Delaware or to the 
holders of the Preferred Securities, without the consent of the holders of 
the Preferred Securities, consolidate, merge with or into, or be replaced by 
a limited partnership or trust organized as such under the laws of any state 
of the United States of America; provided, that (i) such successor entity 
either (x) expressly assumes all of the obligations of Corning Delaware under 
the Preferred Securities or (y) substitutes for the Preferred Securities 
other securities having substantially the same terms as the Preferred 
Securities (the "Successor Securities") so long as the Successor Securities 
rank, with respect to participation in the profits or assets of the successor 
entity, at least as high as the Preferred Securities rank with respect to 
participation in the profits or assets of Corning Delaware, (ii) Corning 
expressly acknowledges such successor entity as the holder of the 
Subordinated Debentures, (iii) such merger, consolidation, or replacement 
does not cause the Preferred Securities (or any Successor Securities) to be 
delisted by any national securities exchange or other organization on which 
the Preferred Securities are then listed, (iv) such merger, consolidation or 
replacement does not cause the Preferred Securities (including any Successor 
Securities) to be downgraded by any nationally recognized statistical rating 
organization, (v) such merger, consolidation or replacement does not 
adversely affect the powers, preferences and other special rights of the 
holders of the Preferred Securities (including any Successor Securities) in 
any material respect (other than with respect to any dilution of the holders' 
interest in the new entity), (vi) prior to such merger, consolidation or 
replacement Corning has received an opinion of nationally recognized 
independent counsel to Corning Delaware experienced in such matters to the 
effect that (x) such successor entity will be treated as a partnership for 
federal income tax purposes, (y) following such merger, consolidation or 
replacement, Corning and such successor entity will be in compliance with the 
1940 Act without registering thereunder as an investment company and (z) such 
merger, consolidation or replacement will not adversely affect the limited 
liability of the holders of the Preferred Securities. 

Voting Rights 

Except as provided below and under "--Description of the 
Guarantee--Amendments and Assignment" and as otherwise required by law and 
the Limited Partnership Agreement, the holders of the Preferred Securities 
will have no voting rights. 

If (i) Corning Delaware fails to pay dividends in full on the Preferred 
Securities for 15 consecutive months; (ii) an Event of Default (as defined in 
the Fiscal Agency Agreement) occurs and is continuing with respect to the 
Subordinated Debentures; or (iii) Corning is in default under any of its 
payment obligations under the Guarantee (as described under "--Description of 
the Guarantee"), then the holders of the Preferred Securities will be 
entitled to appoint and authorize a special general partner (a "Special 
General Partner") to enforce Corning Delaware's rights under the Subordinated 
Debentures, enforce the rights of the holders of Preferred Securities under 
the Guarantee and enforce the rights of the holders to receive dividends on 
the Preferred Securities. For purposes of determining whether Corning 
Delaware has failed to pay dividends in full for 15 consecutive months, 
dividends shall be deemed to remain in arrears, notwithstanding any partial 
payments in respect thereof, until all accumulated and unpaid dividends have 
been or contemporaneously are paid. Not later than 30 days after such right 
to appoint a Special General 

Partner arises, the General Partner will convene a meeting to elect a Special 
General Partner. If the General Partner fails to convene such meeting within 
such 30-day period, the holders of 10% of the aggregate liquidation 
preference of the Preferred Securities then outstanding will be entitled to 
convene such meeting. Any Special General Partner so appointed shall vacate 
office immediately if Corning Delaware (or Corning pursuant to the Guarantee) 
shall have paid in full all accumulated and unpaid dividends on the Preferred 
Securities or such default or breach, as the case may be, shall have been 
cured. Notwithstanding the appointment of any such Special General Partner, 
Corning will retain all rights as obligor under the Subordinated Debentures, 
including the right to extend the interest payment period as provided under 
"--Description of the Subordinated Debentures--Option to Extend Interest 
Payment Period." 

If any proposed amendment to the Limited Partnership Agreement provides for, 
or the General Partner otherwise proposes to effect , (x) any action that 
would materially adversely affect the powers, preferences or special rights 
of the Preferred Securities, whether by way of amendment to the Limited 
Partnership Agreement or otherwise (including, without limitation, the 
authorization or issuance of any limited partnership interests in Corning 
Delaware ranking, as to participation in the profits or assets of Corning 
Delaware, pari passu with or senior to the Preferred Securities), or (y) the 
dissolution, winding-up or termination of Corning Delaware (other than in 
connection with the exchange of Corning Series C Preferred Stock for 
Preferred Securities upon the occurrence of an Exchange Event or as described 
under "--Merger, Consolidation or Sale of Assets of Corning Delaware"), then 
the holders of outstanding Preferred Securities will be entitled to vote on 
such amendment or action of the General Partner (but not on any other 
amendment or action), and such amendment or action shall not be effective 
except with the approval of the holders of at least 66-2/3% or more of the 
aggregate liquidation preference of the Preferred Securities then 
outstanding; provided, however, that no such approval shall be required if 
the dissolution, winding-up or termination of Corning Delaware is proposed or 
initiated pursuant to the Limited Partnership Agreement or upon the 
initiation of proceedings, or after proceedings have been initiated, for the 
liquidation, dissolution or winding-up of Corning. 

The rights attached to the Preferred Securities will be deemed to be 
materially adversely affected by the creation or issue of, and a vote of the 
holders of Preferred Securities will be required for the creation or issue 
of, any other partnership interests of Corning Delaware. 

Holders of Preferred Securities will have no preemptive rights. 

So long as any Subordinated Debentures are held by Corning Delaware, the 
General Partner shall not (i) direct the time, method and place of conducting 
any proceeding for any remedy available to the Special General Partner or the 
Fiscal Agent (as defined below), or executing any trust or power conferred on 
the Special General Partner or the Fiscal Agent with respect to the 
Subordinated Debentures, (ii) waive any past default, which is waivable under 
the Fiscal Agency Agreement, (iii) exercise any right to rescind or annul a 
declaration that the principal of all the Subordinated Debentures shall be 
due and payable, (iv) consent to any amendment, modification or termination 
of the Subordinated Debentures or of the Fiscal Agency Agreement without, in 
each case, obtaining the prior approval of the holders of at least 66-2/3% or 
more of the aggregate liquidation preference of the Preferred Securities then 
outstanding, provided, however, that where a consent under the Subordinated 
Debentures would require the consent of each holder affected thereby, no such 
consent shall be given by the General Partner without the prior consent of 
each holder of the Preferred Securities. The General Partner shall not revoke 
any action previously authorized or approved by a vote of Preferred 
Securities, without the approval of the holders of Preferred Securities 
representing 66-2/3% or more of the aggregate liquidation preference of the 
Preferred Securities then outstanding. The General Partner shall notify all 
holders of Preferred Securities of any notice of default received from the 
Fiscal Agent with respect to the Subordinated Debentures. 

Any required approval of holders of Preferred Securities may be given at a 
meeting of such holders convened for such purpose or pursuant to written 
consent. Corning Delaware will cause a notice of any meeting at which holders 
of Preferred Securities are entitled to vote, or of any matter upon which 
action by written consent of such holders is to be taken, to be mailed to 
each holder of record of Preferred Securities. Each such notice will include 
a statement setting forth (i) the date of such meeting or the date by which 
such action is to be taken, (ii) a description of any matter on which such 
holders are entitled to vote or of such matter upon which written consent is 
sought and (iii) instructions for the delivery of proxies or consents. 

Holders of the Preferred Securities will not have the right to remove or 
replace the General Partner. 

Book-Entry-Only Issuance--The Depository Trust Company 

DTC will act as securities depository for the Preferred Securities. The 
Preferred Securities will be issued only as fully-registered securities 
registered in the name of Cede & Co. (as nominee for DTC). One or more 
fully-registered global Preferred Security certificates will be issued, 
representing in the aggregate the total number of Preferred Securities, and 
will be deposited with DTC. 

The laws of some jurisdictions require that certain purchasers of securities 
take physical delivery of securities in definitive form. Such laws may impair 
the ability to transfer beneficial interests in a global Preferred Security. 

DTC is a limited-purpose trust company organized under the New York Banking 
Law, a "banking organization" within the meaning of the New York Banking Law, 
a member of the Federal Reserve System, a "clearing corporation" within the 
meaning of the New York Uniform Commercial Code, and a "clearing agency" 
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC 
holds securities that its participants ("Participants") deposit with DTC. DTC 
also facilitates the settlement among Participants of securities 
transactions, such as transfers and pledges, in deposited securities through 
electronic computerized book-entry changes in Participants' accounts, thereby 
eliminating the need for physical movement of securities certificates. Direct 
Participants include securities brokers and dealers, banks, trust companies, 
clearing corporations, and certain other organizations ("Direct 
Participants"). Access to the DTC system is also available to others such as 
securities brokers and dealers, banks and trust companies that clear through 
or maintain a custodial relationship with a Direct Participant, either 
directly or indirectly ("Indirect Participants"). 

Purchases of Preferred Securities within the DTC system must be made by or 
through Direct Participants, which will receive a credit for the Preferred 
Securities on DTC's records. The ownership interest of each actual purchaser 
of a Preferred Security ("Beneficial Owner") is in turn to be recorded on the 
Direct or Indirect Participants' records. Beneficial Owners will not receive 
written confirmation from DTC of their purchases, but Beneficial Owners are 
expected to receive written confirmations providing details of the 
transactions, as well as periodic statements of their holdings, from the 
Direct or Indirect Participants through which the Beneficial Owners purchased 
Preferred Securities. Transfers of ownership interests in Preferred 
Securities are to be accomplished by entries made on the books of 
Participants acting on behalf of Beneficial Owners. Beneficial Owners will 
not receive certificates representing their ownership interests in Preferred 
Securities, except if there is an Event of Default under the Subordinated 
Debentures, or if the book-entry system for the Preferred Securities is 
discontinued. 

DTC has no knowledge of the actual Beneficial Owners of the Preferred 
Securities; DTC's records reflect only the identity of the Direct 
Participants to whose accounts such Preferred Securities are credited, which 
may or may not be the Beneficial Owners. The Participants will remain 
responsible for keeping account of their holdings on behalf of their 
customers. 

Conveyance of notices and other communications by DTC to Direct Participants, 
by Direct Participants to Indirect Participants, and by Direct Participants 
and Indirect Participants to Beneficial Owners will be governed by 
arrangements among them, subject to any statutory or regulatory requirements 
as may be in effect from time to time. 

Redemption notices shall be sent to Cede & Co. If less than all of the 
Preferred Securities are being redeemed, DTC's practice is to determine by 
lot the amount of the interest of each Direct Participant in such securities 
to be redeemed. 

Although voting with respect to the Preferred Securities is limited, in those 
cases where a vote is required, neither DTC nor Cede & Co. will itself 
consent or vote with respect to Preferred Securities. Under its usual 
procedures, DTC would mail an Omnibus Proxy to Corning Delaware as soon as 
possible after the record date. The Omnibus Proxy assigns Cede & Co.'s 
consenting or voting rights to those Direct Participants to whose accounts 
the Preferred Securities are credited on the record date (identified in a 
listing attached to the Omnibus Proxy). 

Dividend payments on the Preferred Securities will be made to DTC. DTC's 
practice is to credit Direct Participants' accounts on the relevant payment 
date in accordance with their respective holdings shown on DTC's records 
unless DTC has reason to believe that it will not receive payments on such 
payment date. Payments by Participants to Beneficial Owners will be governed 
by standing instructions and customary practices and will be the 
responsibility of such Participant and not of DTC, Corning Delaware or 

Corning, subject to any statutory or regulatory requirements as may be in 
effect from time to time. Payment of dividends to DTC is the responsibility 
of Corning Delaware, disbursement of such payments to Direct Participants is 
the responsibility of DTC, and disbursement of such payments to the 
Beneficial Owners is the responsibility of Direct and Indirect Participants. 

Except as provided herein, a Beneficial Owner in a global Preferred Security 
will not be entitled to receive physical delivery of Preferred Securities. 
Accordingly, each Beneficial Owner must rely on the procedures of DTC to 
exercise any rights under the Preferred Securities. 

DTC may discontinue providing its services as securities depository with 
respect to the Preferred Securities at any time by giving reasonable notice 
to Corning Delaware. Under such circumstances, in the event that a successor 
securities depository is not obtained, certificates representing the 
Preferred Securities will be printed and delivered. If an Event of Default 
occurs under the Subordinated Debentures or if Corning Delaware decides to 
discontinue use of the system of book-entry transfers through DTC (or a 
successor depository), certificates representing the Preferred Securities 
will be printed and delivered. 

The information in this section concerning DTC and DTC's book-entry system 
has been obtained from sources that Corning and Corning Delaware believe to 
be reliable, but neither Corning nor Corning Delaware takes responsibility 
for the accuracy thereof. 

Registrar and Transfer Agent 

Harris Trust and Savings Bank will act as registrar and transfer agent for 
the Preferred Securities. 

Registration of transfers of Preferred Securities will be effected without 
charge by or on behalf of Corning Delaware, but upon payment (with the giving 
of such indemnity as Corning Delaware or Corning may require) in respect of 
any tax or other government charges which may be imposed in relation to it. 

Corning Delaware will not be required to register or cause to be registered 
the transfer of Preferred Securities after such Preferred Securities have 
been called for redemption and redeemed. 

Description of Corning Series C Preferred Stock 

As described under "--Preferred Securities--Optional Exchange for Corning 
Series C Preferred Stock" above, the Preferred Securities may be exchanged in 
certain circumstances for Corning Series C Preferred Stock. The following 
description of the principal terms of the Corning Series C Preferred Stock 
does not purport to be complete or to give full effect to the provisions of 
statutory or other law and is qualified in its entirety by reference to the 
Corning Restated Certificate of Incorporation as amended (the "Restated 
Certificate") and the Certificate of Amendment, Preferences and Rights of the 
Corning Series C Preferred Stock (the "Certificate of Amendment"), which are 
filed as exhibits to the Registration Statement of which this Prospectus is a 
part. 

The Board of Directors of Corning has designated, and Corning will keep 
available,           shares (          shares if the Underwriters' 
over-allotment option is exercised in full) of Corning Series C Preferred 
Stock for issuance upon exchange of the Preferred Securities (as described 
under " --Preferred Securities--Optional Exchange for Corning Series C 
Preferred Stock" above). At the time the Preferred Securities are issued, all 
corporate action required in connection with the issuance of the Corning 
Series C Preferred Stock upon the making of an Exchange Election will have 
been taken. The terms of the Corning Series C Preferred Stock, together with 
the provisions of the Guarantee, are substantially identical to those of the 
Preferred Securities with the following principal exceptions: 

  (a) Accumulated and unpaid dividends (including any Additional Interest 
thereon) on the Preferred Securities, if any, at the time of the making of an 
Exchange Election will become accumulated and unpaid dividends on the Corning 
Series C Preferred Stock; 

  (b) If dividends are not paid on the Corning Series C Preferred Stock for 
18 monthly dividend periods, the number of directors of Corning shall be 
increased by two persons and the holders of the Corning Series C Preferred 
Stock will be entitled to elect the persons to fill such positions; 

  (c) Dividends on the Corning Series C Preferred Stock need not be declared 
even if Corning has funds legally available therefor and cash on hand 
sufficient to pay dividends. However, if Corning fails to declare such 
dividends, no dividends would be payable on any other securities of Corning 
ranking pari passu with or junior to the Corning Series C Preferred Stock; 
and 

(d) The Corning Series C Preferred Stock will be perpetual and will not be 
subject to mandatory redemption. 

The Corning Series C Preferred Stock will rank senior to the Corning Common 
Stock and the Corning Series A Preferred Stock. The Corning Series C 
Preferred Stock will rank on a parity with the Series B Preferred Stock with 
respect to the payment of dividends and amounts upon liquidation, dissolution 
or winding-up. In the event dividends are not paid in full on either the 
Corning Series B or Series C Preferred Stock, the holders of the Corning 
Series B and Series C Preferred Stock will share ratably with respect to any 
dividend payment in proportion to the respective amounts of the accumulated 
and unpaid dividends due on such preferred stock . 

In the event of a voluntary or involuntary bankruptcy, liquidation, 
dissolution or winding-up of Corning, the holders of Corning Series C 
Preferred Stock are entitled to receive out of the net assets of Corning, but 
before any distribution is made on any class of securities ranking junior to 
the Corning Series C Preferred Stock, $100 per share in cash plus accumulated 
and unpaid dividends (whether or not earned or declared) to the date of final 
distribution to such holders. After payment of the full amount of the 
liquidation distribution to which they are entitled, the holders of shares of 
Corning Series C Preferred Stock will not be entitled to any further 
participation in any distribution of assets of Corning. 

In the event that the assets available for distribution are insufficient to 
pay in full the liquidation preference to the holders of the Corning Series B 
and Series C Preferred Stock, the holders of such preferred stock will share 
in the remaining assets, based on the proportion of their liquidation 
preference to the entire amount of unpaid liquidation preference. 

So long as the Subordinated Debentures are exchangeable for the Corning 
Series C Preferred Stock, Corning may not authorize or issue any other 
preferred stock ranking senior to the Corning Series C Preferred Stock 
without the approval of the holders of at least 66-2/3% of the aggregate 
liquidation preference of the Preferred Securities then outstanding. However, 
no such vote shall be required for the issuance by Corning of additional 
preferred stock ranking pari passu to the Corning Series C Preferred Stock as 
to the payment of dividends and amounts upon liquidation, dissolution and 
winding-up. 

Description of the Guarantee 

The following is a description of the principal terms and provisions of the 
Guarantee Agreement (the "Guarantee"), which will be executed and delivered 
by Corning for the benefit of the holders from time to time of the Preferred 
Securities. The following description is qualified in its entirety by 
reference to such agreement, a copy of the form of which is filed as an 
exhibit to the Registration Statement of which this Prospectus is a part. 

General 

Pursuant to the Guarantee, Corning will irrevocably and unconditionally 
agree, on a subordinated basis and to the extent set forth therein, to pay in 
full to the holders of the Preferred Securities, the Guarantee Payments (as 
defined below) (except to the extent previously paid by Corning Delaware), as 
and when due, regardless of any defense, right of set-off or counterclaim 
that Corning Delaware may have or assert. The following payments, to the 
extent not paid by Corning Delaware, are the "Guarantee Payments": (a) any 
accumulated and unpaid dividends (including any Additional Interest thereon) 
that have been theretofore declared on the Preferred Securities from monies 
legally available therefor; (b) the Redemption Price payable with respect to 
Preferred Securities called for redemption by Corning Delaware out of funds 
legally available therefor; and (c) upon a liquidation of Corning Delaware, 
the lesser of (i) the Liquidation Distribution and (ii) the amount of assets 
of Corning Delaware available for distribution to holders of Preferred 
Securities in liquidation of Corning Delaware. Corning's obligation to make a 
Guarantee Payment may be satisfied by Corning's direct payment of the 
required amounts to the holders of Preferred Securities or by Corning's 
causing Corning Delaware to pay such amounts to such holders. 

Certain Covenants of Corning 

In the Guarantee, Corning will covenant and agree that, so long as any 
Preferred Securities are outstanding, neither Corning nor any majority owned 
subsidiary of Corning shall declare or pay any dividend or distribution on, 
or redeem, purchase or otherwise acquire or make a liquidation payment with 
respect to, any of Corning's capital stock (other than as a result of a 
reclassification of capital stock or the exchange or conversion of one class 
or series of capital stock for another class or series of capital stock) or 
make any guarantee payments with respect to the foregoing (other than 
payments under the Guarantee or 

dividends or guarantee payments to Corning), if at such time Corning is in 
default with respect to its payment or other obligations under the Guarantee 
or there shall have occurred any event that, with the giving of notice or the 
lapse of time or both, would constitute an Event of Default under the 
Subordinated Debentures. Corning will covenant to take all actions necessary 
to ensure the compliance of its subsidiaries with the above covenant. 

Corning will also covenant that, so long as any Preferred Securities are 
outstanding, it will (a) maintain direct 100% ownership of the partnership 
interests and any other interests in Corning Delaware other than the 
Preferred Securities, (b) cause at least 21% of the total value of Corning 
Delaware and at least 21% of all interest in the capital, income, gain, loss, 
deduction and credit of Corning Delaware to be held by Corning, as General 
Partner, (c) not voluntarily dissolve, wind-up or liquidate itself or Corning 
Delaware, (d) remain the General Partner and timely perform all of its duties 
as General Partner of Corning Delaware (including the duty to cause Corning 
Delaware to declare and pay dividends on the Preferred Securities), unless a 
permitted successor General Partner is appointed, and (e) subject to the 
terms of the Preferred Securities, use reasonable efforts to cause Corning 
Delaware to remain a Delaware limited partnership and otherwise continue to 
be treated as a partnership for United States federal income tax purposes. 

Subordination 

Corning's obligations under the Guarantee to make Guarantee Payments will 
constitute an unsecured obligation of Corning that will rank (i) subordinate 
and junior in right of payment to all liabilities of Corning, (ii) pari passu 
with the Series B Preferred Stock or the most senior preferred or preference 
stock hereafter issued by Corning and with any guarantee now or hereafter 
entered into by Corning in respect of any preferred or preference stock of 
any affiliate of Corning and (iii) senior to Corning Common Stock and the 
Series A Preferred Stock. For purposes of clause (ii) herein, pari passu 
means that any payments to which beneficiaries of the Guarantee are entitled 
must be shared with holders of any preferred or preference stock to which 
Corning's obligations to make Guarantee Payments under the Guarantee are 
stated to be pari passu ("Pari Passu Stock") to the same extent as would be 
required under applicable law if instead the Guarantee constituted a class of 
preferred or preference stock of Corning ranking pari passu with such Pari 
Passu Stock as to such payments. 

Corning's obligations under the Guarantee will constitute a guarantee of 
payment and not of collection. A holder of Preferred Securities may enforce 
such obligations directly against Corning, and Corning waives any right or 
remedy to require that any action be brought against Corning Delaware or any 
other person or entity before proceeding against Corning. Such obligations 
will not be discharged except by payment of the Guarantee Payments in full 
and by complete performance of all obligations of Corning under the 
Guarantee. 

Amendments and Assignment 

The terms of the Guarantee may be amended only with the prior approval of the 
holders of not less than 66-2/3% of the aggregate liquidation preference of 
the Preferred Securities then outstanding. The manner of obtaining any such 
approval of holders of the Preferred Securities will be as set forth in 
"--Preferred Securities--Voting Rights." All provisions contained in the 
Guarantee will bind the successors, assigns, receivers, trustees and 
representatives of Corning and will inure to the benefit of the holders of 
the Preferred Securities. Except in connection with any merger or 
consolidation of Corning with or into another entity or any sale, transfer or 
lease of Corning's assets to another entity permitted under the Guarantee, 
Corning may not assign its rights or delegate its obligations under the 
Guarantee without the prior approval of the holders of not less than 66-2/3% 
of the aggregate liquidation preference of the Preferred Securities then 
outstanding. 

Termination 

Corning's obligation to make Guarantee Payments under the Guarantee will 
terminate as to each holder of Preferred Securities and be of no further 
force and effect upon (a) full payment of the Redemption Price of such 
holder's Preferred Securities, (b) full payment of the amounts payable to 
such holder upon liquidation of Corning Delaware, (c) the distribution of 
Corning Common Stock to such holder in respect of the conversion of the 
Subordinated Debentures into Corning Common Stock or (d) the distribution of 
Corning Series C Preferred Stock to such holder in respect of the exchange of 
the Subordinated Debentures for Corning Series C Preferred Stock. 
Notwithstanding the foregoing, Corning's obligation to make Guarantee 
Payments will continue to be effective or will be reinstated, as the case may 
be, as to a holder if at any time such holder must restore payment of any 
sums paid under the Preferred Securities or under the Guarantee for any 
reason whatsoever. 

Merger 

The Guarantee provides that Corning may merge or consolidate with or into 
another entity or may permit another entity to merge or consolidate with or 
into Corning if (i) at such time no Event of Default (as defined in the 
Fiscal Agency Agreement) shall have occurred and be continuing, or would 
occur as a result of such merger or consolidation and (ii) the survivor of 
such merger or consolidation is an entity organized under the laws of the 
United States or any state thereof, becomes the General Partner, assumes all 
of Corning's obligations under the Guarantee and has a net worth equal to at 
least 10% of the total contributions to Corning Delaware. 

Governing Law 

The Guarantee will be governed by and construed in accordance with the laws 
of the State of New York. 

Description of the Subordinated Debentures 

The following summary of principal terms and provisions of the Subordinated 
Debentures in which Corning Delaware will invest the proceeds of the issuance 
and sale of the Preferred Securities and substantially all of the capital 
contributed to Corning Delaware by the General Partner (the "General Partner 
Payment") does not purport to be complete and is qualified in its entirety by 
reference to the Fiscal Agency Agreement among Corning, Corning Delaware and 
Harris Trust and Savings Bank, as fiscal agent (the "Fiscal Agent"), a form 
of which has been filed as an exhibit to the Registration Statement of which 
this Prospectus is a part. All of the Subordinated Debentures will be issued 
under the Fiscal Agency Agreement. 

General 

The Subordinated Debentures will be limited in aggregate principal amount to 
the sum of the aggregate amount of the proceeds received by Corning Delaware 
from the Offering and the General Partner Payment less 1% of such sum. 

The entire principal amount of the Subordinated Debentures will become due 
and payable, together with any accrued and unpaid interest thereon, including 
Additional Interest (as defined below), on the earliest of            , 2024 
or the date upon which Corning Delaware is dissolved, wound-up, liquidated or 
terminated. 

Prepayment 

Corning will have the right to prepay the Subordinated Debentures, in whole 
or in part (together with any accrued but unpaid interest on the portion 
being prepaid) at any time on or after       , 1998, during the twelve-month 
periods beginning on        , 1998 in each of the following years at the 
following prepayment prices (expressed as a percentage of the principal 
amount of the Subordinated Debentures being prepaid): 



                              Prepayment Price 
Year                      (% of principal amount) 
                                  
1998                                     % 
1999 
2000 
2001 
2002 
2003 
2004 and thereafter 



Interest 

The Subordinated Debentures will bear interest at the rate of     % per annum 
from the original date of issuance, payable monthly in arrears on the last 
day of each calendar month of each year (each an "Interest Payment Date"), 
commencing            , 1994. Interest will compound monthly and will accrue 
at the annual rate of    % on any interest installment not paid when due. 

The amount of interest payable for any period will be computed on the basis 
of twelve 30-day months and a 360-day year and, for any period shorter than a 
full monthly interest period, will be computed on the basis of the actual 
number of days elapsed in such period. In the event that any date on which 
interest is payable on the Subordinated Debentures is not a Business Day, 
then a payment of the interest payable on such date will be made on the next 
succeeding day which is a Business Day (and without any interest or other 
payment in respect of any such delay), except that, if such Business Day is 
in the next succeeding calendar year, such payment shall be made on the 
immediately preceding Business Day, in each case with the same force and 
effect as if made on such date. A "Business Day" shall mean any day other 
than a day on which banking institutions in The City of New York are 
authorized or required by law to close. 

Option to Extend Interest Payment Period 

Corning shall have the right at any time and from time to time during the 
term of the Subordinated Debentures to extend interest payment periods for up 
to 60 months, during which periods interest will compound monthly and during 
which Corning shall have the right to make partial payments of interest or at 
the end of which period Corning shall pay all interest then accrued and 
unpaid (together with such compounded interest); provided that, during any 
such extended interest payment period neither Corning nor any majority-owned 
subsidiary of Corning shall declare or pay any dividend on, or redeem, 
purchase, acquire for value or make a liquidation payment with respect to, 
any of Corning's capital stock or make any guarantee payments with respect to 
the foregoing (other than payments under the Guarantee). Prior to the 
termination of any such extended interest payment period, Corning may further 
extend the interest payment period, provided that such extended interest 
payment period together with all such further extensions thereof may not 
exceed 60 months. Corning shall give Corning Delaware notice of its selection 
of an extended interest payment period one Business Day prior to the earlier 
of (i) the date the related dividends are payable or (ii) the date Corning 
Delaware is required to give notice of the record or payment date of such 
related dividend to the New York Stock Exchange or other applicable 
self-regulatory organization or to holders of the Preferred Securities, but 
in any event not less than two Business Days prior to such record date. The 
General Partner shall give notice of Corning's selection of an extended 
interest payment period to the holders of the Preferred Securities. 

Additional Interest 

Corning shall be required to pay interest upon interest that has not been 
paid on the Subordinated Debentures. Accordingly, in such circumstance, 
Corning will pay an amount of interest (i.e., monthly compounding) on the 
Subordinated Debentures in order that Corning Delaware may pay interest on 
dividends in arrears in respect of the Preferred Securities, i.e., monthly 
compounding (the amounts payable to effect monthly compounding on the 
Subordinated Debentures and on the Preferred Securities being referred to 
herein as "Additional Interest"). 

Set-Off 

Corning shall have the right to set-off any payment it is otherwise required 
to make to the extent that it makes payments under the Guarantee. 

Subordination 

The Fiscal Agency Agreement provides that the Subordinated Debentures are 
subordinate and junior in right of payment to all Senior Indebtedness (as 
defined below) of Corning and will rank pari passu with the claims of 
Corning's general unsecured creditors. 

The term "Senior Indebtedness" is defined to mean the principal of, premium, 
if any, interest on, and any other payment due pursuant to any of the 
following, whether outstanding at the date of execution of the Fiscal Agency 
Agreement or thereafter incurred, created or assumed: 

  (a) all indebtedness of Corning for money borrowed (including any 
indebtedness secured by a mortgage or other lien which is (i) given to secure 
all or part of the purchase price of property subject thereto, whether given 
to the vendor of such property or to another or (ii) existing on property at 
the time of acquisition thereof) but, in either case, excluding trade 
accounts payable or similar accrued liabilities arising in the ordinary 
course of business; 

  (b) all indebtedness of Corning for money borrowed evidenced by notes, 
debentures, bonds or other securities; 

  (c) all lease obligations of Corning which are capitalized on the books of 
Corning in accordance with generally accepted accounting principles; 

  (d) all indebtedness of others of the kinds described in either of the 
preceding clauses (a) or (b) and all lease obligations of others of the kind 
described in the preceding clause (c) assumed by or guaranteed in any manner 
by Corning or in effect guaranteed by Corning through an agreement to 
purchase, contingent or otherwise; 

  (e) all obligations of Corning with respect to letters of credit issued in 
connection with indebtedness of others of the kind described in the preceding 
clauses (a) or (b) or lease obligations of the kind described in the 
preceding clause (c); and 

  (f) all renewals, extensions or refundings of indebtedness of the kinds 
described in any of the preceding clauses (a), (b) or (d), all renewals or 
extensions of lease obligations of the kinds described in either the 
preceding clauses (c) and (d) and all renewals or extensions of obligations 
with respect to letters of credit of the kind described in the preceding 
clause (e); 
unless, in the case of any particular indebtedness, lease obligation, 
renewal, extension, refunding or obligations with respect to letters of 
credit, the instrument or lease creating or evidencing the same or the 
assumption or guarantee of the same expressly provides that such 
indebtedness, lease, obligation, renewal, extension or refunding is not 
superior in right of payment to or is pari passu with the Subordinated 
Debentures. Such Senior Indebtedness shall continue to be Senior Indebtedness 
and entitled to the benefits of the subordination provisions irrespective of 
any amendment, modification or waiver of any term of such Senior 
Indebtedness. As of March 27, 1994, Senior Indebtedness of Corning aggregated 
approximately $1.9 billion. 

Certain Covenants of Corning 

Corning will covenant that neither it nor any majority owned subsidiary of 
Corning will declare or pay any dividend on, or redeem, purchase, acquire for 
value or make a liquidation payment with respect to, any of Corning's capital 
stock, or make any guarantee payments with respect to the foregoing if at 
such time (i) there shall have occurred any event that, with the giving of 
notice or the lapse of time or both would constitute an Event of Default (as 
defined below) under the Subordinated Debentures, (ii) Corning shall be in 
default with respect to its payment or other obligations under the Guarantee 
or (iii) Corning shall have given notice of its selection of an extended 
interest payment period as provided in the Subordinated Debentures and such 
period or any extension thereof shall be continuing. Corning will also 
covenant (i) to remain the General Partner of Corning Delaware, provided that 
any permitted successor of Corning under the Fiscal Agency Agreement may 
succeed to Corning's duties as General Partner, (ii) to cause at least 21% of 
the total value of Corning Delaware and at least 21% of all interests in the 
capital, income, gain, loss, deduction and credit of Corning Delaware to be 
held by Corning, (iii) not to voluntarily dissolve, wind-up or liquidate 
Corning Delaware, (iv) to perform timely all of its duties as General Partner 
(including the duty to pay dividends on the Preferred Securities as described 
under "--Description of the Guarantee--General"), (v) to maintain ownership 
of all partnership interests of Corning Delaware other than the Preferred 
Securities, (vi) to use its reasonable efforts to cause Corning Delaware to 
remain a limited partnership and otherwise to continue to be treated as a 
partnership for United States federal income tax purposes and (vii) to 
exchange Corning Series C Preferred Stock or convert Corning Common Stock 
upon an election by Corning Delaware to exchange or convert the Subordinated 
Debentures. 

Events of Default 

If one or more of the following events (each an "Event of Default") shall 
occur and be continuing while Corning Delaware holds the Subordinated 
Debentures: 

  (a) failure to pay any principal of the Subordinated Debentures when due; 

  (b) failure to pay any interest on the Subordinated Debentures, including 
any Additional Interest, when due and such failure continues for a period of 
10 days; provided that a valid extension of the interest payment period by 
Corning shall not constitute a default in the payment of interest for this 
purpose; 

  (c) failure by Corning to exchange Corning Series C Preferred Stock or 
convert Corning Common Stock upon an election by Corning Delaware to exchange 
or convert the Subordinated Debentures; 

  (d) failure by Corning to perform in any material respect any other 
covenant in the Fiscal Agency Agreement for the benefit of the holders of 
Subordinated Debentures continued for a period of 60 days after written 
notice to Corning from Corning Delaware or any holder of Preferred 
Securities; 

  (e) the dissolution, winding-up, liquidation or termination of Corning 
Delaware; or 

  (f) certain events of bankruptcy, insolvency or liquidation of Corning; 
then Corning Delaware will have the right to declare the principal of and the 
interest on the Subordinated Debentures (including any Additional Interest) 
and any other amounts payable under the Subordinated Debentures to be 
forthwith due and payable and to enforce its other rights as a creditor with 
respect to the Subordinated Debentures. Additionally, under the terms of the 
Preferred Securities, the holders of outstanding Preferred Securities will 
have the rights described above under "--Preferred Securities--Voting 
Rights," including the right to appoint a Special General Partner, which 
Special General Partner shall be authorized to exercise Corning Delaware's 
right to accelerate the principal amount of the Subordinated Debentures and 
to enforce Corning Delaware's other rights as a creditor under the 
Subordinated Debentures. 

Conversion of the Subordinated Debentures 

The Subordinated Debentures will be convertible into Corning Common Stock at 
the option of Corning Delaware at any time on or before the close of business 
on the maturity date thereof at the initial conversion price set forth on the 
cover page of this Prospectus subject to the adjustments described under 
"--Preferred Securities--Conversion Rights." Upon conversion of the Preferred 
Securities, Corning Delaware will convert $100 principal amount of the 
Subordinated Debentures for every two Preferred Securities so converted. 
Corning's delivery to Corning Delaware of the fixed number of shares of 
Corning Common Stock into which the Subordinated Debentures are convertible 
(together with the cash payment, if any, in lieu of fractional shares) will 
be deemed to satisfy Corning's obligation to pay the principal amount of the 
Subordinated Debentures, including any applicable redemption premium, and the 
accrued and unpaid interest attributable to the period from the last date to 
which interest has been paid or duly provided for. 

Exchange of the Subordinated Debentures 

The Subordinated Debentures will be exchangeable for shares of Corning Series 
C Preferred Stock upon an Exchange Event on or before the close of business 
on the maturity date thereof at the rate of two shares of Corning Series C 
Preferred Stock for each $100 principal amount of the Subordinated 
Debentures. Any accumulated and unpaid interest (including Additional 
Interest) on the Subordinated Debentures shall be treated as accrued and 
unpaid dividends on the Corning Series C Preferred Stock. 

Modification of the Fiscal Agency Agreement 

The Fiscal Agency Agreement may be amended by mutual consent of the parties 
in the manner the parties shall agree; provided that, so long as any of the 
Preferred Securities remain outstanding, no such amendment may be made that 
adversely affects the holders of Preferred Securities, and no termination of 
the Fiscal Agency Agreement may occur, and no Event of Default or compliance 
with any covenant under the Fiscal Agency Agreement may be waived by Corning 
Delaware, without the prior consent of the holders of at least 66-2/3% of the 
aggregate liquidation preference of the Preferred Securities then outstanding 
unless and until the Subordinated Debentures and all accrued and unpaid 
interest thereon has been paid in full. 

Governing Law 

The Fiscal Agency Agreement and the Subordinated Debentures will be governed 
by, and construed in accordance with, the laws of the State of New York. 

Information Concerning the Fiscal Agent 

The Fiscal Agent is an agent of Corning and owes no duty to the holders of 
Subordinated Debentures or holders of the Preferred Securities. Corning and 
Corning Delaware have agreed in the Fiscal Agency Agreement to indemnify and 
hold harmless the Fiscal Agent against any losses or damages it may suffer as 
Fiscal Agent. 

Harris Trust and Savings Bank, the Fiscal Agent under the Fiscal Agency 
Agreement, has from time to time engaged in transactions with, or performed 
services for, Corning in the ordinary course of business. 

                     DESCRIPTION OF CORNING CAPITAL STOCK 

General 
The following is a brief summary of certain provisions of the Restated 
Certificate and does not relate to or give effect to provisions of statutory 
or other law except as specifically stated. The Restated Certificate 
authorizes the issuance of 500,000,000 shares of Common Stock. As of May   , 
1994,             shares of Common Stock were outstanding. The rights of 
holders of Corning Common Stock are governed by the Restated Certificate, the 
Company's By-Laws and by the New York Business Corporation Law (the "NYBCL"). 

 Voting Rights 
Subject to the voting of any shares of Series Preferred Stock that may be 
outstanding, voting power is vested in the Common Stock, each share having 
one vote. 

 Preemptive Rights 
The Restated Certificate provides that no holder of Common Stock or Series 
Preferred Stock (as defined below) of the Company shall have any preemptive 
rights except as the Board of Directors of the Company may determine from 
time to time. No such rights have been granted by the Board of Directors of 
the Company. 

 Liquidation Rights 
Subject to the preferential rights of any outstanding Series Preferred Stock, 
in the event of any liquidation of the Company, holders of Common Stock then 
outstanding are entitled to share ratably in the assets of the Company 
available for distribution to such holders. 

 Dividend Rights and Restrictions 
Subject to any preferential rights of any outstanding Series Preferred Stock 
and any outstanding Preferred Securities, such dividends as may be determined 
by the Board of Directors may be declared and paid on the Common Stock from 
time to time out of any funds legally available therefor. The Company has 
regularly paid cash dividends since 1881 and currently expects to continue to 
pay cash dividends. The Company's current quarterly cash dividend is $.17 per 
share of Common Stock. The continued declaration of dividends by the Board of 
Directors of the Company is subject to, among other things, the Company's 
current and prospective earnings, financial condition and capital 
requirements and such other factors as the Board of Directors may deem 
relevant. 

 Other Provisions 
The Common Stock has no redemption, sinking fund or conversion privileges 
applicable thereto and holders of Common Stock are not liable to assessments 
or to further call. 

Series Preferred Stock 
The Restated Certificate authorizes the issuance of up to 10,000,000 shares 
of Series Preferred Stock, par value $100 per share (the "Series Preferred 
Stock"). The Company's Board of Directors has the authority to issue such 
shares from time to time, without stockholder approval, and the authority to 
determine the designations, preferences, rights, including voting rights, and 
restrictions of such shares, subject to the NYBCL. Pursuant to this 
authority, the Board of Directors has designated 600,000 shares of Series 
Preferred Stock as Series A Preferred Stock, 500,000 shares of Series 
Preferred Stock as Series B Preferred Stock (the "Series B Preferred Stock"), 
and     shares of Series Preferred Stock as Series 

C Preferred Stock. No other class of Series Preferred Stock has been 
designated by the Board of Directors. For a description of the Corning Series 
C Preferred Stock, see "Description of Securities Offered--Corning Series C 
Preferred Stock." 

 Series B Preferred Stock 
Cumulative cash dividends at the rate of 8% per annum are payable on shares 
of the Series B Preferred Stock that have been issued. The Company has 
regularly paid dividends on the Series B Preferred Stock. No dividends may be 
paid or declared on the Series A Preferred Stock or the Common Stock unless 
all dividends for all prior dividend periods have been paid or declared on 
the Series B Preferred Stock, the Series C Preferred Stock and the Preferred 
Securities. 

Holders of Series B Preferred Stock are entitled to vote, voting together 
with the Common Stock and not as a separate class, on all matters submitted 
to holders of the Common Stock, each share of Series B Preferred Stock having 
four votes, subject to adjustment. 

Holders of Series B Preferred Stock have no preemptive rights. In the event 
of a liquidation, dissolution or winding-up of the Company, holders of Series 
B Preferred Stock shall be entitled to receive a distribution in the amount 
of $100 per share, plus accrued and unpaid dividends, before any distribution 
on the Common Stock or Series A Preferred Stock. 

The Series B Preferred Stock is redeemable, in whole or in part, at the 
election of the Company, at any time, at the following redemption prices per 
share: 


 During the Twelve- 
Month Period 
 Beginning October 1,   Price Per Share 
                     
1993                    $104.00 
1994                    $103.00 
1995                    $102.00 
1996                    $101.00 

  and thereafter at $100.00 per share plus, in each case, accrued and unpaid 
dividends. 

The Series B Preferred Stock is subject to redemption, at the option of the 
holder, at any time upon five Business Days' notice, at a redemption price 
equal to $100 plus accrued and unpaid dividends, if the proceeds are 
necessary (i) to make a distribution pursuant to an investment election made 
under the employee benefit plan or (ii) to satisfy any indebtedness to which 
the employee benefit plan is subject, provided that such payment is necessary 
to remedy or prevent a default under such indebtedness. 

The Company, at its option, may make payment of the redemption price required 
upon redemption of shares of Series B Preferred Stock in cash or in shares of 
Common Stock, or in any combination of such shares and cash. 

The Series B Preferred Stock is convertible at the option of the holder, at 
any time, into Common Stock at a conversion price of $25 per share of Common 
Stock, each share of Series B Preferred Stock being valued at $100 for the 
purpose of such conversion, producing a conversion ratio equal to four shares 
of Common Stock for each share of Series B Preferred Stock so converted, 
subject to certain adjustments to prevent dilution. 

Preferred Share Purchase Rights 
Attached to each share of Common Stock is one preferred share purchase right 
("Right"). Each Right entitles the registered holder to purchase from the 
Company one four-hundredth of a share of Series A Preferred Stock at a price 
of $62.50 per one four-hundredth of a share of Series A Preferred Stock (the 
"Exercise Price"), subject to adjustment. The Rights expire on July 15, 1996 
(the "Final Expiration Date"), unless the Final Expiration Date is extended 
or unless the Rights are earlier redeemed by the Company. 

The Rights represented by the certificates for Common Stock, are not 
exercisable, and are not transferable apart from the Common Stock, until the 
earlier of (i) ten days following the public announcement by the Company or 
an Acquiring Person (as defined below) that a person or group has acquired 
beneficial ownership of 20% or more of the Company's Common Stock (an 
"Acquiring Person") or (ii) ten business days (or such later date as the 
Board of Directors may determine) after the commencement or first public 
announcement of a tender or exchange offer that would result in a person or 
group beneficially owning 20% or more of the Company's outstanding Common 
Stock (the earlier of such dates being called the 

"Distribution Date"). Separate certificates for the Rights will be mailed to 
holders of record of the Common Stock as of such date. The Rights could then 
begin trading separately from the Common Stock. 

Generally, in the event that a person or group becomes an Acquiring Person, 
each Right, other than the Rights owned by the Acquiring Person, will 
thereafter entitle the holder to receive, upon exercise of the Right, Common 
Stock having a value equal to two times the Exercise Price of the Right. In 
the event that the Company is acquired in a merger, consolidation, or other 
business combination transaction or more than 50% of the Company's assets, 
cash flow or earning power is sold or transferred, each Right, other than the 
Rights owned by an Acquiring Person, will thereafter entitle the holder 
thereof to receive, upon the exercise of the Right, common stock of the 
surviving corporation having a value equal to two times the Exercise Price of 
the Right. 

The Rights are redeemable in whole, but not in part, at $.0125 per Right at 
any time on or prior to any person or group becoming an Acquiring Person, 
provided that the Rights may no longer be redeemed if such person or group 
shall have acquired beneficial ownership of 90% or more of the Common Stock. 
The right to exercise the Rights terminates at the time that the Board of 
Directors elects to redeem the Rights. Notice of redemption shall be given by 
mailing such notice to the registered holders of the Rights. At no time will 
the Rights have any voting rights. The Rights Agent is Harris Trust and 
Savings Bank (the "Rights Agent"). 

The exercise price payable, and the number of shares of Series A Preferred 
Stock or other securities or property issuable, upon exercise of the Rights 
are subject to adjustment from time to time to prevent dilution (i) in the 
event of a stock dividend on, or a subdivision, combination or 
reclassification of, the shares of Series A Preferred Stock, (ii) upon the 
grant to holders of the shares of Series A Preferred Stock of certain rights 
or warrants to subscribe for or purchase shares of Series A Preferred Stock 
at a price, or securities convertible into shares of Series A Preferred Stock 
with a conversion price, less than the then current market price of the 
shares of Series A Preferred Stock or (iii) upon the distribution to holders 
of the shares of Series A Preferred Stock of evidences of indebtedness or 
assets (excluding regular periodic cash dividends paid out of earnings or 
retained earnings or dividends payable in shares of Series A Preferred Stock) 
or of subscription rights or warrants (other than those referred to above). 

The number of outstanding Rights and the number of one four-hundredths of a 
share of Series A Preferred Stock issuable upon exercise of each Right are 
also subject to adjustment in the event of a stock split of, or stock 
dividend on, or subdivision, consolidation or combination of, the Common 
Stock prior to the Distribution Date. With certain exceptions, no adjustment 
in the exercise price will be required until cumulative adjustments require 
an adjustment of at least 1% in such exercise price. 

Upon exercise of the Rights, no fractional shares of Series A Preferred Stock 
will be issued (other than fractions which are integral multiples of one 
four-hundredth of a share, which may, at the election of the Company, be 
evidenced by depositary receipts) and in lieu thereof an adjustment in cash 
will be made. 

The Rights have certain anti-takeover effects. The Rights may cause 
substantial dilution to a person or group that attempts to acquire the 
Company on terms not approved by the Board of Directors of the Company, 
except pursuant to an offer conditioned on a substantial number of Rights 
being acquired. The Rights should not interfere with any merger or other 
business combination approved by the Board of Directors since the Rights may 
be redeemed by the Company at $.0125 per Right prior to the fifteenth day 
after the acquisition by a person or group of beneficial ownership of 20% or 
more of the Common Stock (subject to certain exceptions). 

The shares of Series A Preferred Stock purchasable upon exercise of the 
Rights will rank junior to all other series of the Company's Preferred Stock 
(including the Series B and Series C Preferred Stock) or any similar stock 
that specifically provides that they shall rank prior to the shares of Series 
A Preferred Stock. The shares of Series A Preferred Stock will be 
nonredeemable. Each share of Series A Preferred Stock will be entitled to a 
minimum preferential quarterly dividend of $10 per share, but will be 
entitled to an aggregate dividend of 100 times the dividend declared per 
share of Common Stock. In the event of liquidation, the holders of the shares 
of Series A Preferred Stock will be entitled to a minimum preferential 
liquidation payment of $100 per share, but will be entitled to an aggregate 
payment of 100 times the payment made per share of Common Stock. Each share 
of Series A Preferred Stock will have 100 votes, voting together with the 
Common Stock. In the event of any merger, consolidation or other transaction 
in which Common Stock is exchanged, each share of Series A Preferred Stock 
will be entitled to receive 100 times 

the amount and type of consideration received per share of Common Stock. 
These rights are protected by customary antidilution provisions. Because of 
the nature of the Series A Preferred Stock's dividend, liquidation and voting 
rights, the value of the interest in a share of Series A Preferred Stock 
purchasable upon the exercise of each Right should approximate the value of 
one share of Common Stock. 

The foregoing description of the Rights does not purport to be complete and 
is qualified in its entirety by reference to the description of the Rights 
contained in the Rights Agreement, dated as of July 2, 1986 between the 
Company and the Rights Agent, as amended by the Amended Rights Agreement, 
dated as of October 4, 1989, included as an exhibit to this Registration 
Statement. 

Corning's Fair Price Amendment 
In 1985, the Company's stockholders adopted an amendment (the "Fair Price 
Amendment") to the Restated Certificate that, in general, requires the 
approval by the holders of at least 80% of the voting power of the 
outstanding capital stock of the Company (other than the Series C Preferred 
Stock) entitled to vote generally in the election of directors (the "Voting 
Stock") as a condition for mergers and certain other business combinations 
with any beneficial owner of more than 10% of such voting power unless (1) 
the transaction is approved by at least a majority of the Continuing 
Directors (as defined in the Restated Certificate) or (2) certain minimum 
price, form of consideration and procedural requirements are met. Certain 
terms used herein are defined in the Restated Certificate. 

Amendment or repeal of this provision or the adoption of any provision 
inconsistent therewith would require the affirmative vote of at least 80% of 
the Voting Stock unless the proposed amendment or repeal or the adoption of 
the inconsistent provisions were approved by two-thirds of the entire Board 
of Directors and a majority of the Continuing Directors. 

Certain Other Provisions of the Restated Certificate and By-Laws 
In addition to the Preferred Share Purchase Rights and the Fair Price 
Amendment, the Restated Certificate and By-Laws contain other provisions that 
may discourage a third party from seeking to acquire the Company or to 
commence a proxy contest or other takeover-related action. The Company has 
classified its Board of Directors such that one-third of the Board is elected 
each year to three-year terms of office. In addition, holders of Common Stock 
may remove a Director from office at any time prior to the expiration of his 
or her term only with cause and by vote of a majority of holders of Common 
Stock outstanding. These provisions, together with provisions concerning the 
size of the Board and requiring that premature vacancies on the Board be 
filled only by a majority of the entire Board, may not be amended, altered or 
repealed, nor may the Company adopt any provisions inconsistent therewith, 
without the affirmative vote of at least 80% of the Voting Stock of the 
Company or the approval of two-thirds of the entire Board of Directors. 

The Company's By-Laws contain certain procedural requirements with respect to 
the nomination of directors by stockholders that require, among other things, 
delivery of notice by such stockholders to the Secretary of the Company not 
later than 60 days nor more than 90 days prior to the date of the 
stockholders meeting at which such nomination is to be considered. The 
By-Laws do not provide that a meeting of the Board of Directors may be called 
by stockholders. 

The Restated Certificate provides that no director will be liable to the 
Company or its stockholders for a breach of duty as a director except as 
provided by the NYBCL. 

The effect of these provisions may be to deter attempts either to obtain 
control of the Company or to acquire a substantial amount of its stock, even 
if such a proposed transaction were at a significant premium over the 
then-prevailing market value of the Common Stock, or to deter attempts to 
remove the Board of Directors and management of the Company, even though some 
or a majority of the holders of Common Stock may believe such actions to be 
beneficial. 

                  CERTAIN FEDERAL INCOME TAX CONSIDERATIONS 

General 
The following is a summary of certain federal income tax considerations 
relevant to the purchase, ownership and disposition of the Preferred 
Securities. This summary does not purport to deal with all aspects of federal 
income taxation that may be relevant to holders of the Preferred Securities, 
nor to certain types of holders subject to special treatment under the 
federal income tax laws (for example, banks, life insurance companies, 
dealers, tax-exempt organizations, persons whose functional currency is not 
the 

U.S. dollar or foreign persons and foreign entities). This discussion is 
based upon current provisions of the Internal Revenue Code of 1986, as 
amended (the "Code"), the Treasury regulations (proposed, temporary and 
final) promulgated thereunder, judicial decisions and Internal Revenue 
Service ("IRS") rulings, all of which are subject to change, which change may 
be retroactively applied in a manner that could adversely affect a holder of 
the Preferred Securities. Unless otherwise indicated, the information below 
is directed at initial purchasers that acquire Preferred Securities at 
original issue for their initial offering price, and that hold Preferred 
Securities as capital assets (generally property held for investment.) 

Prospective investors are advised to consult their own tax advisors with 
regard to the federal income, estate and gift tax consequences of purchasing, 
holding and disposing of Preferred Securities, as well as the tax 
consequences arising under the laws of any state, foreign country or other 
jurisdiction. The following summary represents the opinion of Shearman & 
Sterling, special federal income tax counsel to Corning and Corning Delaware, 
insofar as such summary relates to matters of law and legal conclusions. An 
opinion of counsel, however, is not binding on the IRS or the courts, and 
neither Corning nor Corning Delaware have sought, nor do they intend to seek, 
a ruling from the IRS that the position as reflected in the discussion below 
will be accepted by the IRS. Moreover, there are no cases or rulings on 
similar transactions and, as a result, there can be no assurance that the IRS 
will agree with the conclusions and discussions below. 

Tax Classification 
While the following matters are not free from doubt, Shearman & Sterling is 
of the opinion that (i) Corning Delaware will be classified as a partnership 
for federal income tax purposes and not as an association (or as a publicly 
traded partnership) taxable as a corporation, and (ii) the Subordinated 
Debentures will be classified as indebtedness of Corning for such purposes. 
This advice is based upon the terms of the Limited Partnership Agreement, the 
Fiscal Agency Agreement and related documents and transactions as described 
in this Prospectus (and assumes ongoing compliance with such agreement and 
documents) and upon the conclusion by Shearman & Sterling that the nature of 
the income of Corning Delaware will exempt it from the rule that certain 
publicly traded partnerships are taxable as corporations (assuming Corning 
Delaware will not register under the 1940 Act). 

Prospective investors and their advisors should be aware, however, that the 
proper characterization of the arrangement involving Corning Delaware, the 
Preferred Securities and the Subordinated Debentures is not entirely clear 
and the IRS has recently announced that it will scrutinize and may challenge 
certain aspects of transactions with some features that are similar to this 
arrangement. If, contrary to the opinion of tax counsel, the IRS successfully 
argued that Corning Delaware should be taxable as a corporation, Corning 
Delaware (including the income from the Subordinated Debentures) would be 
subject to federal income tax at corporate rates and distributions to holders 
of Preferred Securities likely would be taxable as dividend income to the 
extent of the earnings and profits of Corning Delaware. Similarly, if, 
contrary to the opinion of tax counsel, the IRS successfully asserted that 
the Subordinated Debentures were properly classified as stock or other equity 
in Corning, then payments on the Subordinated Debentures would not be 
deductible by Corning as interest, but instead likely would be treated as 
distributions to holders taxable as dividends to the extent of the earnings 
and profits of Corning. Either event could have adverse tax consequences for 
certain holders and could result in substantially reduced amounts payable to 
holders, as well as resulting in holders receiving Corning Series C Preferred 
Stock in a taxable transaction that has other possible adverse tax 
consequences. See "--Exchange of Preferred Securities for Corning Series C 
Preferred Stock." 

Prospective investors should also be aware that the IRS recently issued a 
proposed Treasury regulation under which the IRS can disregard or recast the 
form of a transaction if a partnership is formed or availed of in connection 
with a transaction (or series of related transactions) "with a principal 
purpose of substantially reducing the present value of the partners' 
aggregate federal tax liability" in a manner inconsistent with the intent of 
the partnership provisions of the Code. In the view of Shearman & Sterling, 
based in part upon certain representations of Corning, Corning Delaware 
should not be considered to be formed or availed of with such a purpose 
because the transactions involving Corning Delaware are not of the type 
intended to fall within the scope of such proposed regulation. There can be 
no assurance, however, that the IRS will agree with this view. Unless 
otherwise noted, the remainder of this summary assumes, in accordance with 
the opinion of Shearman & Sterling, that Corning Delaware is properly 
classified as a partnership and the Subordinated Debentures are properly 
classified as indebtedness of Corning for income tax purposes. 

Income from Preferred Securities 
As partners in a partnership, each holder of Preferred Securities will be 
required to include in gross income its distributive share of the net income 
of Corning Delaware, which net income generally will be equal to the amount 
of interest received or accrued on the Subordinated Debentures. See 
"--Original Issue Discount" below. Any amount so included in a holder's gross 
income will increase its tax basis in the Preferred Securities, and the 
amount of distributions of cash or other property by Corning Delaware to the 
holder will reduce such holder's tax basis in the Preferred Securities. No 
portion of the amounts received on the Preferred Securities will be eligible 
for the dividends received deduction. 

Corning Delaware does not presently intend to make an election under Section 
754 of the Code. As a result, a subsequent purchaser of Preferred Securities 
will not be permitted to adjust the tax basis in its allocable share of 
Corning Delaware's assets so as to reflect any difference between its 
purchase price for the Preferred Securities and the underlying tax basis of 
Corning Delaware in its assets. As a result, a Security holder may be 
allocated a larger or smaller amount of Corning Delaware income than would 
otherwise be appropriate based upon such holder's purchase price for the 
Preferred Security. 

Under Section 708 of the Code, Corning Delaware will be deemed to terminate 
for federal income tax purposes if 50% or more of the capital and profits 
interests in Corning Delaware are sold or exchanged within a 12-month period. 
If such a termination occurs, there will be a closing of the partnership's 
taxable year for all partners and Corning Delaware will be considered to 
distribute its assets to the partners, who would then be treated as 
recontributing those assets to Corning Delaware, as a new partnership. 
Corning Delaware will not comply with certain technical requirements that 
might apply when such a constructive termination occurs. As a result, Corning 
Delaware may be subject to certain tax penalties and may incur additional 
expenses if it is required to comply with those requirements. (Furthermore, 
Corning Delaware might not be able to comply due to lack of data.) 

Original Issue Discount 
Under Treasury Regulations, the stated interest payments on the Subordinated 
Debentures will be treated as "original issue discount" because of the option 
that Corning has, under the terms of the Subordinated Debentures, to extend 
interest payment periods for up to 60 months. Under the Code, holders of debt 
with original issue discount must include that discount in income on an 
economic accrual basis and before the receipt of cash attributable to the 
interest regardless of their method of tax accounting. In the event that the 
interest payment period is extended, Corning Delaware will continue to accrue 
income equal to the amount of the interest payment due at the end of the 
extended interest payment period on an economic accrual basis over the length 
of the extended interest payment period. 

Accrued income will be allocated, but not distributed, to holders of record 
on the Business Day preceding the last day of each calendar month. As a 
result, holders of record during an extended interest payment period will 
include interest in gross income in advance of the receipt of cash, and any 
such holders who dispose of Preferred Securities prior to the record date for 
the payment of dividends following such extended interest payment period will 
include such holder's allocable share of such interest in gross income but 
will not receive any cash related thereto. The tax basis of a Preferred 
Security will be increased by the amount of any interest that is included in 
income without a corresponding receipt of cash and will be decreased when and 
if such cash is subsequently received from Corning Delaware. 

Under Treasury Regulations, no portion of the price paid for a debt 
instrument is to be allocated to the right to convert into, or the right to 
exchange for, stock of the corporation issuing the debt instrument. As such, 
neither Corning Delaware nor the holders of Preferred Securities should be 
required to allocate a portion of their purchase price to the right of 
Corning Delaware to convert the Subordinated Debentures into Corning Common 
Stock or to exchange the Subordinated Debentures for Corning Series C 
Preferred Stock. Nevertheless, the IRS may take a contrary view, or may 
require an allocation of purchase price to the Corning guarantee. If the IRS 
were successful in requiring an allocation, a holder could be required to 
include an incremental amount of original issue discount (in addition to 
stated interest) in income over the life of the Preferred Securities. Corning 
intends to take the position that no allocation that would result in 
additional original issue discount (in excess of stated interest) is 
required. 

Disposition of Preferred Securities 
Generally, capital gain or loss will be recognized on a sale of Preferred 
Securities, including a complete redemption for cash, equal to the difference 
between the amount realized and the holder's tax basis in the Preferred 
Securities sold. Gain or loss recognized by a holder on the sale or exchange 
of a Preferred 

Security held for more than one year generally will be taxable as long-term 
capital gain or loss. The adjusted tax basis of the Preferred Securities sold 
will equal the amount paid for the Preferred Securities, plus accrued but 
unpaid original issue discount, if any, as described herein allocated to such 
holder and reduced by any cash or other property distributed to such holder 
by Corning Delaware. A holder acquiring Preferred Securities at different 
prices may be required to maintain a single aggregate adjusted tax basis in 
such Preferred Securities, and, upon sale or other disposition of some of the 
Preferred Securities, allocate a pro rata portion of such aggregate tax basis 
to the Preferred Securities sold (rather than maintaining a separate tax 
basis in each Preferred Security for purposes of computing gain or loss on a 
sale of that Preferred Security). 

If a holder of Preferred Securities is required to recognize an aggregate 
amount of income over the life of the Preferred Security that exceeds the 
aggregate cash distribution with respect thereto, such excess generally will 
result in a capital loss upon the retirement of the Preferred Securities. 

Corning Delaware is obligated to redeem the Preferred Securities for cash on 
repayment or on any prepayment of the Subordinated Debentures. Corning will 
pay a prepayment premium to Corning Delaware if Corning prepays any portion 
of the Subordinated Debentures before       , 2004 and Corning Delaware will 
pay a corresponding redemption premium to holders of Preferred Securities 
whose Preferred Securities are redeemed before          , 2004. Corning 
Delaware will receive a redemption premium on any repayments of the 
Subordinated Debentures by Corning before       , 2004. Corning Delaware will 
recognize capital gain on such prepayments of the Subordinated Debentures to 
the extent of the prepayment premium. Corning Delaware's gain will be 
allocated to the holder whose Preferred Securities are redeemed, and the 
allocated gain should increase the holder's adjusted tax basis in its 
Preferred Securities. A holder who has a basis increase due to such 
allocation to the holder of Corning Delaware's gain on Corning's prepayment 
of the Subordinated Debentures will not have additional taxable gain 
attributable to the redemption premium upon Corning Delaware's redemption of 
the holder's Preferred Securities. 

Corning Delaware will allocate income to holders of Preferred Securities on 
the Business Day preceding the last day of each calendar month. As a result 
of such monthly allocation, a holder purchasing Preferred Securities may be 
allocated tax items attributable to periods before the transfer. The use of 
such monthly allocation may not be permitted under applicable Treasury 
Regulations, and, if not allowed, taxable income of Corning Delaware may be 
reallocated among holders of Preferred Securities. The General Partner is 
authorized to adjust allocations if necessary to reflect the economic income 
of holders or as otherwise required by the Code. 

Exchange of Preferred Securities for Corning Common Stock 
The Subordinated Debentures may be converted at the option of Corning 
Delaware into Corning Common Stock and the Limited Partnership Agreement 
allows a holder to direct Corning Delaware to make such a conversion for the 
holder to the extent of such holder's allocable share of the Subordinated 
Debentures and distribute Corning Common Stock to such holder in exchange for 
such holder's Preferred Securities. A holder's exchange of Preferred 
Securities through Corning Delaware for shares of Corning Common Stock should 
be treated as a distribution of Corning Common Stock by Corning Delaware in 
redemption of all or part of the holder's interest in a partnership. Neither 
a holder nor Corning Delaware should recognize gain or loss on the conversion 
or the exchange. However, when Corning Delaware exchanges Subordinated 
Debentures with Corning to obtain shares of Corning Common Stock for delivery 
to a holder in exchange for the holder's Preferred Securities, interest 
income which has accrued on that portion of the Subordinated Debentures since 
the last interest payment date will be allocated to the holder exchanging 
Preferred Securities, but no cash will be distributed in connection with this 
income. As a result, holders of Preferred Securities who exchange these 
securities on a date other than an interest payment date will include some 
interest in gross income but will not receive any cash related to that 
interest. This income will increase the holder's basis in its Preferred 
Securities. In addition, under the current advance ruling policy of the IRS, 
cash received by Corning Delaware in lieu of a fractional share of Corning 
Common Stock upon conversion of all or part of the Subordinated Debentures 
should be treated as a payment in exchange for the fractional share of 
Corning Common Stock. This treatment will result in Corning Delaware 
recognizing gain or loss, if any, measured by the difference between the cash 
received for the fractional share interest and Corning Delaware's tax basis 
in such fractional share interest. This gain will be allocated to the holder 
of Preferred Securities who converts those shares through Corning Delaware 
into shares of Corning Common Stock, and the cash which Corning Delaware 
receives in lieu of a fractional share interest will be distributed to that 
holder. 

In the case of an exchange upon conversion for all of the holder's Preferred 
Securities, the holder's tax basis in the shares of Corning Common Stock 
received will equal the holder's tax basis in the Preferred Securities 
immediately before such exchange increased by the gain allocated to the 
holder on any fractional share interest redeemed by Corning and reduced by 
any cash distributed to the holder with respect to such fractional share 
interest. In the case of an exchange for less than all of a holder's 
Preferred Securities, the holder's tax basis in the shares of Corning Common 
Stock received will be the lesser of the holder's tax basis in such holder's 
Preferred Securities immediately before such exchange or Corning Delaware's 
tax basis in the portion of the Subordinated Debentures converted for those 
shares of Corning Common Stock increased by any gain recognized by Corning 
Delaware on conversion in respect of any fractional share interest redeemed 
by Corning and decreased by any cash received by Corning Delaware in 
connection therewith. In such case, the holder's aggregate tax basis in its 
remaining Preferred Securities will be its aggregate tax basis in such 
holder's Preferred Securities immediately before such redemption, reduced 
(but not below zero) by the sum of Corning Delaware's tax basis in the shares 
of Corning Common Stock delivered in such redemption as described above, and 
the amount of cash paid in lieu of fractional shares, if any. 

The holding period for Corning Common Stock received in exchange for a 
holder's Preferred Securities will begin on the date Corning Delaware 
acquired the Subordinated Debentures, except that the holding period of 
Corning Common Stock received by Corning Delaware in satisfaction of accrued 
but unpaid interest, if any, may commence on the date of conversion, although 
there is no authority precisely on point. Gain or loss upon a sale or other 
disposition of the Corning Common Stock will be capital gain or loss if the 
Corning Common Stock is a capital asset in the hands of the holder. 

Holders should be aware that the tax treatment of the conversion feature is 
not entirely clear and the IRS might argue that, for tax purposes, the 
conversion of a Subordinated Debenture into Corning Common Stock (and Corning 
Delaware's subsequent distribution of such stock to a holder) should be 
treated as an exchange by the holder of its Preferred Securities against 
Corning for Corning Common Stock. While unlikely, if this argument were 
asserted and sustained, the conversion of the Preferred Securities by a 
holder for Corning Common Stock would be a taxable transaction in which a 
holder recognizes capital gain or loss. 

Adjustment of Conversion Price 
Treasury Regulations promulgated under section 305 of the Code would treat 
Corning Delaware (and, thus, holders of Preferred Securities) as having 
received a constructive distribution from Corning in the event the conversion 
ratio of the Subordinated Debentures were adjusted if (i) as a result of such 
adjustment, the proportionate interest of Corning Delaware in the assets or 
earnings and profits of Corning were increased and (ii) the adjustment was 
not made pursuant to a bona fide, reasonable antidilution formula. An 
adjustment in the conversion ratio would not be considered made pursuant to 
such a formula if the adjustment was made to compensate for certain taxable 
distributions with respect to the stock into which the Subordinated 
Debentures are convertible. Thus, under certain circumstances, a reduction in 
the conversion price for the Subordinated Debentures is likely to be taxable 
to Corning Delaware as a dividend to the extent of the current or accumulated 
earnings and profits of Corning. The holders of the Preferred Securities 
would be required to include their allocable share of such constructive 
dividend in gross income but will not receive any cash related thereto. In 
addition, the failure to fully adjust the conversion price of the 
Subordinated Debentures to reflect distributions of stock dividends with 
respect to the Corning Common Stock may result in a taxable dividend to the 
holders of the Corning Common Stock. 

Similarly, under Section 305 of the Code, adjustments to the conversion price 
of the Corning Series C Preferred Stock, which may occur under certain 
circumstances, may result in deemed dividend income to holders of the Corning 
Series C Preferred Stock if such adjustments are not made pursuant to a bona 
fide, reasonable antidilution formula, and failure to make such adjustments 
to the conversion price of the Corning Series C Preferred Stock may result in 
deemed dividend income to holders of the Corning Common Stock. 

Exchange of Preferred Securities for Corning Series C Preferred Stock 
Under certain circumstances, as described under the caption "Description of 
Securities Offered--Preferred Securities--Optional Exchange for Corning 
Series C Preferred Stock," Subordinated Debentures will be exchanged by 
Corning Delaware for Corning Series C Preferred Stock which would then be 
distributed to the holders of the Preferred Securities in liquidation of 
Corning Delaware. If Corning Delaware is taxed as a partnership, Corning 
Delaware's subsequent distribution of the Corning Series C Pre- 

ferred Stock to the holders in exchange for the holders' Preferred Securities 
should be treated as a non-taxable exchange to Corning Delaware and to each 
holder of Preferred Securities and should result in the holder of such 
Preferred Securities receiving an aggregate tax basis in the Corning Series C 
Preferred Stock equal to such holder's aggregate tax basis in its Preferred 
Securities. A holder's holding period in the Corning Series C Preferred Stock 
so received in liquidation of Corning Delaware as a partnership would include 
the period for which the Preferred Securities were held by such holder. Under 
a change in law, a change in legal interpretation or the other circumstances 
giving rise to a Tax Event, however, the liquidation of Corning Delaware 
could be a taxable event both to Corning Delaware and to holders of the 
Preferred Securities. 

Notwithstanding partnership treatment, however, holders should be aware that 
the taxation of the exchange feature is not entirely clear and the IRS might 
argue that, for tax purposes, the exchange of Subordinated Debentures for 
Corning Series C Preferred Stock (and Corning Delaware's subsequent 
distribution of such stock to a holder) should be treated as an exchange by 
the holder of its Preferred Securities against Corning for Corning Series C 
Preferred Stock. If this argument were asserted and sustained, the exchange 
of the Preferred Securities by a holder for Corning Series C Preferred Stock 
would be a taxable transaction in which a holder recognizes capital gain or 
loss. 

If Corning exercises its option to extend interest payment periods under the 
Subordinated Debentures for more than fifteen months, holders will have the 
option of causing Corning Delaware to exchange the Subordinated Debentures 
for Corning Series C Preferred Stock and to distribute such stock to such 
holders in exchange for their Preferred Securities. Holders who exchange 
their Preferred Securities for Corning Series C Preferred Stock, however, may 
be subject to additional income tax to the extent accrued but unpaid interest 
(taxed as original issue discount) on the Subordinated Debentures is 
converted into accumulated and unpaid dividends on the Corning Series C 
Preferred Stock received in exchange for the Preferred Securities. This is 
because holders first would be subject to tax on their distributive share of 
Corning Delaware's unpaid interest income on the Subordinated Debentures as 
such interest accrues during the extended period (with a corresponding 
increase in the tax basis of the holders' Preferred Securities). If the 
holders exchange their Preferred Securities for Corning Series C Preferred 
Stock when there is accrued but unpaid interest due on the Subordinated 
Debentures and such unpaid interest is converted into accumulated and unpaid 
dividends on the Corning Series C Preferred Stock received in the exchange, 
the holders would be subject to tax again on the previously taxed accrued 
interest to the extent Corning subsequently paid such amount as dividends to 
the holders. Moreover, if such accumulated, unpaid dividends on the Corning 
Series C Preferred Stock were considered to cause the dividend rate on the 
Corning Series C Preferred Stock to decline in the future, then, under 
section 1059(f) of the Code, such dividends may be treated as "extraordinary 
dividends" for tax purposes (regardless of the period over which a holder has 
or is deemed to have held the Corning Series C Preferred Stock) and corporate 
holders generally would be required to reduce their tax basis in their 
Corning Series C Preferred Stock by the "non-taxed" portion of such dividends 
(which portion generally reflects the dividends received deduction claimed by 
the corporate holder with respect to such extraordinary dividend). 

Holders are urged to consult their own tax advisors as to the tax 
consequences to them of an exchange of their Preferred Securities for Corning 
Series C Preferred Stock. 

Corning Delaware Information Returns and Audit Procedures 
The General Partner in Corning Delaware will furnish each holder with a 
Schedule K-1 each year setting forth such holder's allocable share of income 
for the prior calendar year. The General Partner is required to furnish such 
Schedule K-1 as soon as practicable following the end of the taxable year, 
but in any event prior to March 15th of each succeeding year. 

Any person who holds Preferred Securities as nominee for another person is 
required to furnish to Corning Delaware (a) the name, address and taxpayer 
identification number of the beneficial owner and the nominee; (b) 
information as to whether the beneficial owner is (i) a person that is not a 
United States person, (ii) a foreign government, an international 
organization or any wholly owned agency or instrumentality of either of the 
foregoing, or (iii) a tax-exempt entity; (c) the amount and description of 
Preferred Securities held, acquired or transferred for the beneficial owner; 
and (d) certain information including the dates of acquisitions and 
transfers, means of acquisitions and transfers, and acquisition cost for 
purchases, as well as the amount of net proceeds from sales. Brokers and 
financial institutions are required to furnish additional information, 
including whether they are United States persons and certain information on 
Preferred Securities they acquire, hold or transfer for their own accounts. A 
penalty of $50 per failure (up to 

a maximum of $100,000 per calendar year) is imposed by the Code for failure 
to report such information to Corning Delaware. The nominee is required to 
supply the beneficial owners of the Preferred Securities with the information 
furnished to Corning Delaware. 

The General Partner, as the tax matters partner, will be responsible for 
representing the holders in any dispute with the IRS. The Code provides for 
administrative examination of a partnership as if the partnership were a 
separate and distinct taxpayer. Generally, the statute of limitations for 
partnership items does not expire before three years since the later of the 
filing or the last date for filing of the partnership information return. Any 
adverse determination following an audit of the return of Corning Delaware by 
the appropriate taxing authorities could result in an adjustment of the 
returns of the holders, and, under certain circumstances, a holder may be 
precluded from separately litigating a proposed adjustment to the items of 
the partnership. An adjustment could also result in an audit of a holder's 
return and adjustments of items not related to the income and losses of 
Corning Delaware. 

Foreign Holders 
Ownership of Preferred Securities by nonresident aliens, foreign corporations 
and other foreign persons raises tax considerations unique to such persons 
and may have substantially adverse tax consequences to them. Therefore, 
prospective investors who are foreign persons or which are foreign entities 
are urged to consult with their U.S. tax advisors as to whether an investment 
in a Preferred Security represents an appropriate investment in light of 
those unique tax considerations and possible adverse tax consequences. 

Backup Withholding and Information Reporting 
In general, information reporting requirements will apply to payments to 
noncorporate United States holders of the proceeds of the sale of Preferred 
Securities, Corning Series C Preferred Stock or Corning Common Stock within 
the United States and "backup withholding" at a rate of 31% will apply to 
such payments if the United States holder fails to provide an accurate 
taxpayer identification number. 

Proposed Tax Legislation 
Legislation pending before Congress would apply special rules to "large 
partnerships," generally defined as partnerships with at least 250 partners 
during a taxable year (counting towards such total each owner during the year 
of a partnership interest that is transferred during the year). Under the 
legislation, certain computations are made at the partnership level rather 
than the partner level. In particular, taxable income is calculated at the 
partnership level, and is calculated generally in the same manner as for an 
individual, except that 70% of miscellaneous itemized deductions (such as 
expenses for the production of non-business income) are disallowed. As a 
result, all partners (including corporations) might have a portion of their 
share of partnership deductions (other than interest expense) disallowed. In 
addition, large partnerships would become subject to new audit procedures; 
among other things, an adjustment to taxable income of the partnership for a 
prior year would flow through to current partners in the year the audit was 
settled, and the partnership itself (rather than the partners) would be 
subject to any applicable interest or penalties. Moreover, under the 
legislation, a large partnership would not be deemed to have terminated under 
Section 708 of the Code solely because 50% or more of its interests are sold 
or exchanged within a 12-month period. As proposed, these rules would apply 
to partnership taxable years ending on or after December 31, 1994. 

This legislation is currently pending before Congress; however, no prediction 
can be made whether this proposal or similar legislation might be enacted in 
the future, or the ultimate effective date of such legislation or whether the 
number of holders would cause Corning Delaware to be considered a "large 
partnership." 

THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL 
INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON A HOLDER'S 
PARTICULAR SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT 
TO THE TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF 
THE PREFERRED SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, 
FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR 
OTHER TAX LAWS. 

UNDERWRITING 

Subject to the terms and conditions of the Underwriting Agreement, Corning 
Delaware has agreed to sell to each of the Underwriters named below, and each 
of such Underwriters, for whom Goldman, Sachs & Co. and Lazard Freres & Co. 
are acting as representatives, has severally agreed to purchase from Corning 
Delaware, the respective number of Preferred Securities set forth opposite 
its name below: 


                                 Number of 
Underwriter                Preferred Securities 
                            
Goldman, Sachs & Co. 
Lazard Freres & Co. 

  Total                               ,000 

Under the terms and conditions of the Underwriting Agreement, the 
Underwriters are committed to take and pay for all such Preferred Securities 
offered hereby, if any are taken. 

The Underwriters propose to offer the Preferred Securities in part directly 
to the public at the initial public offering price set forth on the cover 
page of this Prospectus, and in part to certain securities dealers at such 
price less a concession of $  .   per Preferred Security. The Underwriters 
may allow, and such dealers may reallow, a concession not in excess of $  . 
per Preferred Security to certain brokers and dealers. After the Preferred 
Securities are released for sale to the public, the offering price and other 
selling terms may from time to time be varied by the representatives. 

In view of the fact that the proceeds from the sale of the Preferred 
Securities will be used by Corning Delaware to purchase the Subordinated 
Debentures of Corning, the Underwriting Agreement provides that Corning will 
pay as compensation to the Underwriters ("Underwriters' Compensation"), a 
commission of $  .   per Preferred Security. 

Corning and Corning Delaware have granted the Underwriters an option 
exercisable for 30 days after the date of this Prospectus to purchase up to 
an aggregate of      additional Preferred Securities solely to cover 
over-allotments, if any. If the Underwriters exercise their over-allotment 
option, the Underwriters have severally agreed, subject to certain 
conditions, to purchase approximately the same percentage thereof that the 
number of Preferred Securities to be purchased by each of them, as shown in 
the foregoing table, bears to the      Preferred Securities offered. 

Corning and Corning Delaware have agreed not to offer, sell, contract to 
sell, or otherwise dispose of any shares of Corning Common Stock, any other 
capital stock of Corning, any other security convertible into or exercisable 
or exchangeable for Corning Common Stock or any such other capital stock or 
debt securities substantially similar to the Subordinated Debentures for a 
period of 90 days after the date of this Prospectus without the prior written 
consent of the representatives, except for (a) the Preferred Securities 
offered hereby, (b) Corning Common Stock or Corning Series C Preferred Stock 
issued or delivered upon conversion or exchange of the Subordinated 
Debentures, (c) securities issued or delivered upon conversion, exchange or 
exercise of any other securities of Corning outstanding on the date of this 
Prospectus, (d) securities issued pursuant to Corning's stock option or other 
benefit or incentive plans maintained for its officers, directors or 
employees, (e) securities issued in connection with mergers, acqui- 

sitions or similar transactions or (f) partnership interests of Corning 
Delaware issued to Corning in connection with the sale of the over-allotment 
shares in order to maintain Corning's 21% interest in the total capital of 
Corning Delaware. 

Certain of the Underwriters are customers of, or engage in transactions with, 
and from time to time have performed services for, Corning and its 
subsidiaries and associated companies in the ordinary course of business. 

Prior to this Offering, there has been no public market for the Preferred 
Securities. Application will be made to list the Preferred Securities on the 
New York Stock Exchange under the symbol "GLW pfM." In order to meet one of 
the requirements for listing the Preferred Securities on the New York Stock 
Exchange, the Underwriters will undertake to sell lots of 100 or more 
Preferred Securities to a minimum of 2,000 beneficial holders. 

Corning and Corning Delaware have agreed to indemnify the several 
Underwriters against certain liabilities, including liabilities under the 
Securities Act of 1933, as amended. 

                          VALIDITY OF THE SECURITIES 

The validity of the Preferred Securities, the Guarantee, the Corning Common 
Stock and the Corning Series C Preferred Stock issuable upon conversion or 
exchange of the Subordinated Debentures will be passed upon for Corning by 
William C. Ughetta, Esq., Senior Vice President and General Counsel of 
Corning, and for the Underwriters by Sullivan & Cromwell, New York, New York. 
Additionally, certain matters as to (i) the formation of Corning Delaware and 
the authority of Corning and Corning Delaware to enter into certain 
agreements relating to the transaction and (ii) United States taxation will 
be passed upon by Shearman & Sterling, New York, New York. Mr. Ughetta owns 
substantially less than 1% of the outstanding shares of Corning Common Stock.

Item 17. Undertakings. 
Corning and Corning Delaware hereby undertake (1) to file, during any period 
in which offers or sales are being made, a post-effective amendment to this 
Registration Statement: (i) to include any prospectus required by Section 
10(a)(3) of the Securities Act of 1993; (ii) to reflect in the prospectus any 
facts or events arising after the effective date of this Registration 
Statement (or the most recent post-effective amendment thereto) which, 
individually or in the aggregate, represent a fundamental change in the 
information set forth in the Registration Statement; and (iii) to include any 
material information with respect to the plan of distribution not previously 
disclosed in this Registration Statement or any material change to such 
information in the Registration Statement; provided, however, that paragraphs 
(1)(i) and (1)(ii) do not apply if the information required to be included in 
a post-effective amendment thereby is contained in periodic reports filed by 
the Company pursuant to Section 13 or Section 15(d) of the Securities 
Exchange Act of 1934 that are incorporated by reference in the Registration 
Statement; (2) that, for the purpose of determining any liability under the 
Securities Act of 1933, each such post-effective amendment shall be deemed to 
be a new registration statement relating to the securities offered therein, 
and the offering of such securities at that time shall be deemed to be the 
initial bona fide offering thereof; (3) to remove from registration by means 
of post-effective amendment any of the securities being registered which 
remain unsold at the termination of the offering; and (4) that, for purposes 
of determining any liability under the Securities Act of 1933, each filing of 
Corning's annual report pursuant to Section 13(a) or Section 15(d) of the 
Securities Exchange Act of 1934 that is incorporated by reference in this 
Registration Statement shall be deemed to be a new Registration Statement 
relating to the securities offered therein, and the offering of such 
securities at that time shall be deemed to be the initial bona fide offering 
thereof. 

Corning and Corning Delaware hereby undertake that, (1) for purposes of 
determining any liability under the Securities Act, the information omitted 
from the form of prospectus filed as part of this registration statement in 
reliance upon Rule 430A and contained in a form of prospectus filed by the 
registrants pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities 
Act shall be deemed to be part of this registration statement as of the time 
it was declared effective; and (2) for purposes of determining any liability 
under the Securities Act, each post-effective amendment that contains a form 
of prospectus shall be deemed to be a new registration statement relating to 
the securities offered therein, and the offering of such securities at that 
time shall be deemed to be the initial bona fide offering thereof. 

Insofar as indemnification for liabilities arising under the Securities Act 
may be permitted to directors, officers and controlling persons of Corning 
and Corning Delaware pursuant to the foregoing provisions, or otherwise, 
Corning and Corning Delaware have been advised that in the opinion of the 
Securities and Exchange Commission such indemnification is against public 
policy as expressed in such Act and is, therefore, unenforceable. In the 
event a claim for indemnification against such liabilities (other than the 
payment by Corning or Corning Delaware of expenses incurred or paid by a 
director, officer or controlling person of Corning or Corning Delaware in the 
successful defense of any action, suit or proceeding) is asserted by such 
director, officer or controlling person in connection with the securities 
being registered, Corning and Corning Delaware will, unless in the opinion of 
its counsel the matter has been settled by controlling precedent, submit to a 
court of appropriate jurisdiction the question whether such indemnification 
by it is against public policy as expressed in such Act and will be governed 
by the final adjudication of such issue.
