Corning Delaware 
   
6% Convertible Monthly Income Preferred Securities 
("Convertible MIPS"*) 
(liquidation preference $50 per security) 
guaranteed to the extent set forth herein by, and convertible into Common 
Stock of, Corning Incorporated 
    
   
The 6,500,000 6% 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 6% of the 
liquidation preference of $50 per Preferred Security, accruing from July 21,
1994 and payable monthly in arrears on the last day of each calendar month of 
each year, commencing July 31, 1994 ("dividends"). See "Description of 
Securities Offered--Preferred Securities--Dividends." 
    
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." 
                                                      (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) in which Corning Delaware will invest the proceeds 
from the sale of the Preferred Securities 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.

</TABLE>
    
(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"), $1.125 per Preferred Security (or $7,312,500
in the aggregate). See "Underwriting." 
    
   
(3) Expenses of the offering which are payable by Corning are estimated to be 
$710,000. 
    
   
(4) Corning Delaware and Corning have granted the Underwriters an option for 
30 days to purchase up to an additional 975,000 Preferred Securities at the 
initial public offering price per share, solely to cover over-allotments. 
Corning will pay to the Underwriters, as Underwriters' Compensation, $1.125 
per Preferred Security purchased pursuant to this option. If such option is 
exercised in full, the total initial public offering price, underwriting 
commission and proceeds to Corning Delaware will be $373,750,000, $8,409,375 
and $365,340,625, respectively. 
See "Underwriting." 
    
<PAGE>
   
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 July 21, 1994. 

Goldman, Sachs & Co.                                       Lazard Freres & Co. 

                 The date of this Prospectus is July 14, 1994.

(continued from previous page) 
   
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 1.2821 shares of Corning Common Stock for each Preferred
Security (equivalent to a conversion price of $39.00 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 July 13, 1994 was $32.125 per share. 
The Preferred Securities are also subject to exchange through Corning 
Delaware, in whole but not in part, into shares of Series C Cumulative 
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 similar 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 August 5, 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 irrevocably and unconditionally guarantee, on a subordinated 
basis and to the extent set forth herein, to pay in full the 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 to the extent of funds legally available 
therefor 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. 
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. 
If Corning fails to make interest payments on the Subordinated 
Debentures, Corning Delaware will have insufficient funds to pay 
dividends on the Preferred Securities. The guarantee does not 
cover payment of dividends when Corning Delaware does not have 
sufficient funds to pay such dividends. In such event (other than as a 
result of an extended interest period discussed below), holders of the 
Preferred Securities will be entitled to elect a Special General 
Partner to enforce Corning Delaware's rights under the Subordinated 
Debentures. See "Description of Securities Offered--Preferred 
Securities--Voting Rights." 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. If Corning selects an interest 
period longer than one month, it will be prohibited from paying any 
dividends on Junior Stock (as defined under "Description of Securities 
Offered--Description of the Guarantee--Subordination"). 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 in exchange for the Preferred 
Securities. For a discussion of the United States federal income tax 
consequences of such an extended interest payment period, including the fact 
that holders will be required to include interest accruing on the 
Subordinated Debentures in their gross income for United States federal 
income tax purposes in advance of the receipt of cash dividend payments from 
Corning Delaware, see "Certain Federal Income Tax Considerations--
Original Issue Discount." 

The Subordinated Debentures are 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 June 19, 1994, Corning had approximately $1.9 billion of 
Senior Indebtedness outstanding. 

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 in 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."

                            AVAILABLE INFORMATION 

Corning is subject to the informational requirements of the Securities 
Exchange Act of 1934, as amended (the "Exchange Act"), and in accordance 
therewith files reports, proxy statements and other information with the 
Securities and Exchange Commission (the "Commission"). Reports, proxy 
statements and other information filed by Corning may be inspected and copied 
at the public reference facilities maintained by the Commission at Room 1024, 
450 Fifth Street, N.W., Washington, D.C. 20549, and at the Commission's 
Regional Offices located at 7 World Trade Center, 13th Floor, New York, New 
York 10048 and 500 West Madison Street, 14th Floor, Chicago, Illinois 60661. 
Copies of such materials may be obtained upon written request from the Public 
Reference Section of the Commission at 450 Fifth Street, N.W., Washington, 
D.C. 20549, at prescribed rates. In addition, such materials may also be 
inspected and copied at the offices of the New York Stock Exchange, Inc. (the 
"NYSE"), 20 Broad Street, New York, New York 10005. 

Corning and Corning Delaware have filed with the Commission a registration 
statement on Form S-3 (herein, together with all amendments and exhibits, 
referred to as the "Registration Statement") under the Securities Act of 
1933, as amended. This Prospectus does not contain all of the information set 
forth in the Registration Statement, certain parts of which are omitted in 
accordance with the rules and regulations of the Commission. For further 
information, reference is hereby made to the Registration Statement. 


No separate financial statements of Corning Delaware have been included 
herein. Corning and Corning Delaware do not consider that such financial 
statements would be material to holders of Preferred Securities because 
Corning Delaware is a newly organized special purpose entity, has no 
operating history and no independent operations and is not engaged in, and 
does not propose to engage in, any activity other than as described under 
"Corning Delaware." Further, Corning believes that financial statements
of Corning Delaware are not material to the holders of the Preferred 
Securities since the Preferred Securities have been structured to provide a
guarantee by Corning of the Preferred Securities such that the holders of the
Preferred Securities with respect to the payment of dividends and amounts 
upon liquidation, dissolution and winding up are at least in the same 
position vis-a-vis the assets of Corning as a preferred stockholder of Corning.
See "Corning Delaware" and "Description of Securities Offered-- Preferred 
Securities," "-Description of the Guarantee" and "-Description of the 
Subordinated Debentures." Corning beneficially owns directly or indirectly 
all of Corning Delaware's partnership interests (other than the Preferred 
Securities).

                             PROSPECTUS SUMMARY 

The following summary is qualified in its entirety by the more detailed 
information and consolidated financial statements (including the notes 
thereto) appearing elsewhere or incorporated by reference in this Prospectus. 
Unless otherwise specified, references herein to the "Company" or "Corning" 
refer to Corning Incorporated and its consolidated subsidiaries. Prospective 
investors should carefully read the entire Prospectus. 

                               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 more than 50 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 ("Dow Chemical") 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 and on June 7, 1994, merged 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 

Second Quarter 1994 Results 
On June 28, 1994, Corning released its results for the quarter ended June 19, 
1994. Corning's second quarter net income totaled $111.4 million, or $0.54 
per share, compared to 1993's second quarter net income of $89.8 million, or 
$0.47 per share. Corning's first half net income totaled $169.4 million, or 
$0.82 per share, compared to 1993's first half net income of $139.6 million, 
or $0.73 per share. 

Second quarter and first half sales increased approximately 20% to $1.1 
billion and $2.1 billion, respectively. Approximately half of the increase in 
both periods was due to recent acquisitions, including the 1993 acquisition 
of Damon. 

Earnings from consolidated operations increased 24% and 16% in the second 
quarter and first half, respectively. Sales and consolidated earnings growth 
in both the second quarter and first half resulted from strength across all 
business segments. 

Equity company results for the second quarter and first half increased 24% 
and 46%, respectively, over the prior year period primarily due to continued 
improvement from operations 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 1993. 

Creation of Environmental Testing Services Company 
On June 28, 1994, Corning and International Technology Corporation 
("International Technology") created a jointly owned company to which Corning 
transferred the net assets of its environmental testing laboratory business 
and International Technology transferred the assets of its IT Analytical 
Services business. Corning and International Technology each own 50 percent 
of the company. 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 Clinical Laboratory Testing Businesses 
On June 7, 1994, Corning acquired 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. In connection with this transaction, 
Corning has granted to the stockholders of Maryland Medical registration 
rights with respect to the shares of Corning Common Stock they received. 
Pursuant to such rights, Corning is required to file a registration statement 
covering all 4.5 million shares of Corning Common Stock no later than 90 days 
after the written request of the designated representative of such 
stockholders. As of July 13, 1994, no such request had been received by 
Corning. 

On June 1, 1994, Corning signed a definitive agreement to acquire all of the 
outstanding shares of the capital stock of Nichols Institute ("Nichols") in a 
transaction to be accounted for as a pooling of interests. Under the terms of 
the agreement, Corning will exchange newly issued and registered shares of 
Corning Common Stock with a value equal to up to $13 for each share of the 
capital stock of Nichols. Using an assumed price of $33 per share of Corning 
Common Stock and the number of shares of, and options to purchase, the 
capital stock of Nichols presently outstanding, approximately 6.7 million 
shares of Corning Common Stock and 
options to purchase approximately 1 million shares of Corning Common Stock 
will be issued in the transaction. Substantially all of the options to 
purchase shares of Corning Common Stock will be exercisable immediately 
following the closing of the transaction. In no event will more than 9.6 
million shares of Corning Common Stock be issued and reserved for the 
exercise of options granted in connection with such transaction. The final 
exchange ratio of shares of Corning Common Stock for shares of Nichols 
capital stock will be determined by the price of Corning Common Stock during 
the 10-day trading period ending on the fifth trading day prior to the date 
of the Nichols stockholders meeting held to approve the transaction. The 
transaction is subject to regulatory approval and is expected to close in the 
second half of 1994. 

Corning's consolidated financial statements for periods prior to these 
transactions will not be restated since the acquisitions are not material to 
Corning's financial position or results of operations. Corning will likely 
record a one-time charge of up to $10 million after-tax in the third quarter 
for transaction costs associated with these acquisitions and may possibly 
record an additional one-time charge of up to $25 million after-tax in the 
second half of 1994 for the integration of the Nichols and Maryland Medical 
operations into MetPath. 

For a discussion of the registration rights granted to the stockholders of 
Maryland Medical and the registration of the shares of Corning Common Stock 
to be issued in the Nichols transaction, see "Description of Corning Capital 
Stock--Common Stock Eligible for Future Sale." 

Sale of Parkersburg Plant 
In May 1994, Corning sold its Parkersburg, W.Va., glass-tubing products plant 
to Schott Corporation, a subsidiary of the Schott Group, for $57 million and 
decided to exit several minor product lines in the specialty materials 
segment. The net gain from these transactions is not material. 

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 were used to retire a portion of the debt incurred in connection 
with the acquisition of Damon in August 1993. 


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 (in which Corning Delaware will invest the proceeds from the sale 
of the Preferred Securities), may be deferred for up to 60 months.

                           Delaware and Corning have granted the Underwriters an option for 30 days to 
                           purchase up to an additional 975,000 Preferred Securities at the initial public 
                           offering price solely to cover over-allotments, if any. 
    
   
Dividends                  Dividends on the Preferred Securities will be cumulative from July 21, 1994 
                           and will be payable at the annual rate of 6% 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 July 31, 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 or the occurrence of 
                           a Tax Event 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 
                           in exchange for the Preferred Securities. If the Preferred Securities remain 
                           outstanding for three months after the date of notice 
                           of a Tax Event or, if occurring earlier than the end of such three-month period, 
                           the date on which a vote is taken at any special partnership meeting (or, in 
                           lieu of such a meeting, the date of a written consent) by the holders of the 
                           Preferred Securities on the matter of whether 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 Additional 
                           Taxes (as defined under "Description of Securities Offered--Preferred 
                           Securities--Dividends"). See "Description of Securities Offered--Description 
                           of the Subordinated Debentures--Option to Extend Payment Period" and "Description 
                           of Securities Offered--Preferred Securities--Optional Exchange for Corning 
                           Series C Preferred 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 1.2821 shares of Corning Common Stock for each Preferred Security 
                           (equivalent to a conversion price of $39.00 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 
                           a portion of the Subordinated Debentures into Corning Common Stock and will 
                           distribute such shares of Corning Common Stock to such holder in exchange for 
                           the Preferred Securities of such holder that have been so converted. See "Description 
                           of Securities Offered--Preferred Securities--Conversion Rights." 

Redemption                 From time to time on and after August 5, 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 failure of holders of the Preferred Securities to receive, for 15 consecutive 
  Preferred Stock          months, the full amount of dividend payments or the occurrence of a Tax Event, 
                           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 in exchange for 
                           such Preferred Securities. 
                           The Corning Series C Preferred Stock will have dividend, conversion, optional 
                           redemption, and other terms substantially similar 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 not be subject to 
                           mandatory redemption. 

Guarantee                  Pursuant to a Guarantee Agreement (the "Guarantee"), Corning will irrevocably and 
                           unconditionally agree, on a subordinated basis and to the extent set forth therein, 
                           to pay in full (a) the dividends (including any Additional Dividends thereon, as 
                           defined under "Description of Securities Offered--Preferred Securities--Additional 
                           Dividends") by Corning Delaware on the Preferred Securities, if, and 
                           to the extent declared from funds legally available therefor, (b) the redemption 
                           price (including all accumulated and unpaid dividends) of the Preferred Securities, 
                           to the extent of funds legally available therefor, 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"). A holder of Preferred Securities may enforce Corning's obligations
                           under the Guarantee directly against Corning, and Corning waives any right
                           or remedy to require that an action be brought against Corning Delaware or any
                           other person or entity before proceeding against Corning. See "Description 
                           of Securities Offered--Description of the Guarantee." 

Voting Rights              Generally, holders of the Preferred Securities will not have any voting rights. 
                           However, upon an Event of Default under the Subordinated Debentures (as described 
                           under "Description of Securities Offered--Subordinated Debentures--Events of 
                           Default"), a failure by Corning Delaware to pay dividends in full for 15 consecutive 
                           months (other than as a result of an election by Corning to defer interest payments)
                           or a default by Corning under the Guarantee, 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 to cause Corning Delaware to exchange all of the outstanding Subordinated 
                           Debentures for shares of Corning Series C Preferred Stock at the Exchange Price 
                           and distribute such shares to the holders of Preferred Securities in exchange 
                           for the Preferred Securities. 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               The Subordinated Debentures will have a maturity of 30 years and will bear interest 
  Debentures               at the rate of 6% 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 Junior Stock (as defined under "Description of Securities 
                           Offered--Description of the Guarantee--Subordination") 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 as described above under "Optional Exchange for Corning Series C Preferred 
                           Stock." On and after August 5, 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 June 19, 1994, Corning 
                           had approximately $1.9 billion of Senior Indebtedness outstanding.

                        SUMMARY FINANCIAL INFORMATION 

The following is a summary of certain consolidated financial information that 
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 
financial data should be read in conjunction with the information set forth 
in "Selected Consolidated Financial Data" and "Management's Discussion and 
Analysis of Financial Condition and Results of Operations," and the 
historical financial information and related notes incorporated by reference 
in this Prospectus. 

The unaudited pro forma combined financial information set forth below 
reflects the estimated impact on Corning's financial statements of the 
acquisition of Damon, the merger with Costar Corporation ("Costar"), the 
transaction with Unilab Corporation ("Unilab") and several other completed 
1993 transactions, the Vitro transaction completed in January 1994, the 
acquisition of the optical-fiber and optical-cable businesses of Northern 
Telecom Limited ("NTL") by Corning and Siecor Corporation ("Siecor") in 
February 1994, the merger with Maryland Medical completed in June 1994, the 
pending acquisition of Nichols and the Offering (collectively, the 
"Transactions"). Such pro forma data assume the Transactions had been 
completed on January 4, 1993, for income statement data and by March 27, 
1994, for balance sheet data. The unaudited pro forma combined financial 
information set forth below is derived from, and should be read in 
conjunction with, the unaudited pro forma combined financial information 
included elsewhere in this Prospectus and the historical financial statements 
of Corning and Damon incorporated by reference into this Prospectus. The 
unaudited pro forma combined financial information is presented for 
informational purposes only, and is not necessarily indicative of the results 
of operations or financial position which would have been achieved had the 
Transactions been completed on the dates indicated or the results that may be 
attained in the future.

                                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 approximately $317,000,000 (approximately
$364,000,000 if the Underwriters' over-allotment option is exercised in 
full) to retire all or 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 Junior Stock (as defined under "Description of Securities Offered--
Description of the Guarantee--Subordination") during any such extended period 
and until all dividend arrearages have been paid in full. However, in the 
event such a deferral continues for more than 15 months, the holders of a 
majority of the aggregate 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 that holders who exchange their Preferred Securities for 
Corning Series C Preferred Stock may be subject to additional income tax to 
the extent accrued but unpaid interest 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, 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 United States 
federal income tax purposes which will be allocated, but not distributed, to 
holders of record of Preferred Securities. As a result, such holders 
would be required to include such interest in gross income for United States 
federal income tax purposes in advance of the receipt of cash dividend 
payments from Corning Delaware and would 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." 

Tax Event 

In the case of a Tax Event, the holders of a majority of the aggregate 
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 by Additional Taxes. 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. For a discussion of 
the taxation of such an exchange to holders, including the possibility that 
holders who exchange their Preferred Securities for Corning Series C 
Preferred Stock may be subject to additional income tax to the extent accrued 
but unpaid interest on the Subordinated Debentures is converted into 
accumulated and unpaid divi 

dends on the Corning Series C Preferred Stock received in exchange for the 
Preferred Securities, 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, (ii) the pro forma capitalization of Corning as of such date 
after giving effect to the completed or pending transactions and (iii) the 
pro forma capitalization of the Company as of such date as further adjusted 
to reflect 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.

</TABLE>

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. <PAGE>

(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 during 
an extended interest payment period with respect to the Subordinated 
Debentures, when there is an Event of Default (as defined under "Description 
of Securities Offered--Description of the Subordinated Debentures--Events of 
Default") under the Subordinated Debentures or when Corning has failed to 
make a payment required under the Guarantee. See "Description of Securities 
Offered--Description of the Guarantee--Certain Covenants of Corning." 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. 

<PAGE>
(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 restructuring charge of $156.0 million ($88.1 million 
after-tax and minority interest) as a result of costs to integrate 
the Damon acquisition and a planned company-wide program to reduce assets 
and overhead costs during the next year and other special charges
of $51.0 million ($32.4 million after-tax). The other special charges 
primarily included $36.5 million for the settlement and related legal
expenses incurred in the compromise agreement between MetPath and
the Civil Division of the Department of Justice and $8.0 million
of transaction expenses related to the Costar acquisition. 
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 FINANCIAL INFORMATION 

The Unaudited Pro Forma Combined Financial Information (the "Unaudited Pro 
Forma Information") is presented to reflect the estimated impact on Corning's 
Financial Statements of the following proposed or completed transactions 
(collectively, the "Transactions"): 

* 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 acquisition of Costar in September 1993, the transaction with Unilab in 
November 1993, and other acquisitions completed in 1993 (collectively, the 
"Other 1993 Transactions") which individually and in the aggregate are not 
significant. The Costar merger and the Unilab transaction are described in 
Notes 4 and 5, respectively. 

* The acquisition of the optical-fiber and optical-cable businesses of 
Northern Telecom Limited ("NTL") by Corning and Siecor for $131 million in 
February 1994, the Vitro transaction completed in January 1994 and the merger 
with Maryland Medical for 4.5 million shares of Corning Common Stock in June 
1994 (collectively, the "Completed 1994 Transactions"). The NTL transaction 
has been accounted for as a purchase and the Maryland Medical transaction 
will be accounted for as a pooling of interests. The Vitro transaction is 
described in Note 6. 
The NTL and Vitro transactions were financed by the issuance of 8.0 million 
shares of Corning Common Stock in February 1994. 

* The proposed acquisition of Nichols for an estimated 6.7 million shares of 
Corning Common Stock and options to purchase approximately 1 million shares 
of Corning Common Stock (the "Pending 1994 Transaction"). This transaction 
will be accounted for as a pooling of interests. 


* The issuance by Corning Delaware of $325 million of Preferred Securities in 
the Offering and the use of the net proceeds thereof by Corning to retire a 
significant portion of the indebtedness incurred in connection with the Damon 
transaction. 


The Unaudited Pro Forma Combined Statements of Income for the year ended 
January 2, 1994, and the twelve weeks ended March 27, 1994, assume that the 
Transactions had been completed on January 4, 1993. The Unaudited Pro Forma 
Combined Balance Sheet at March 27, 1994, assumes that the Transactions had 
been completed by that date. Corning's consolidated financial statements for 
periods prior to the two pooling of interests transactions will not be 
restated since the acquisitions are not material to Corning's financial 
position or results of operations. 

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

Corning has completed or has pending several business dispositions 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 Unaudited Pro Forma Information should be read in conjunction with the 
historical financial statements of Corning and Damon incorporated by 
reference into this Prospectus.

                                   CORNING 
         NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION 

Note 1--Basis of Presentation: 
The Unaudited Pro Forma Combined Statements of Income reflect Corning's 
results of operations for the year ended January 2, 1994, and the twelve 
weeks ended March 27, 1994, on a pro forma basis assuming the Transactions 
had been completed as of January 4, 1993. The Unaudited Pro Forma Combined 
Balance Sheet at March 27, 1994, assumes that the Transactions had been 
completed by that date. 

Corning's management believes that the assumptions used in preparing the 
Unaudited 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 Unaudited Pro Forma 
Information. 

Note 2--Pro Forma Adjustments: 
 Statement of Income 
(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, the Other 1993 Transactions and the 
Completed 1994 Transactions of $5.7 million, $1.8 million, and $6.0 million, 
respectively, for the year ended January 2, 1994, and $1.3 million for the 
Completed 1994 Transactions, for the twelve weeks ended March 27, 1994. 

Including $40 million of anticipated costs to restructure Damon's facilities 
as a result of the integration of Corning's and Damon's operations, the 
excess of cost over fair value of tangible net assets acquired in the Damon 
transaction is $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 acquired in the Damon transaction. 

Goodwill totaling $258 million and $190 million resulted from the Other 1993 
Transactions and the Completed 1994 Transactions, respectively, and is being 
amortized over 25 to 40 years. 


(b) The pro forma adjustment represents the elimination of one-time 
restructuring costs of $40.6 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 1993 
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 
1993 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 longer-term debt. During the fourth 
quarter of 1993, Corning extended the terms of the financing agreements to 
December 31, 1995. The pro forma adjustment to interest expense related to 
the Damon transaction is calculated as the weighted average of short-term and 
longer-term interest rates. 

(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 which were 
charged to 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. In addition, tax 
expense has been adjusted to provide taxes on the income of one of the 
Completed 1994 Transactions which was previously a Subchapter S corporation. 
These adjustments are 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 1993 Transactions and the Completed 1994 Transactions. 

(g) The pro forma adjustment to weighted average shares outstanding 
represents the issuance of 5.5 million shares to complete the Costar 
acquisition in September 1993, 12.5 million shares in conjunction with the 
Completed 1994 Transactions and an estimated 6.7 million shares to be issued 
in conjunction with the Pending 1994 Transaction. 
The number of shares to be issued in the Pending 1994 Transaction is 
dependent on the price of Corning Common Stock during the 10-day trading 
period ending on the fifth trading day prior to the date of the Nichols 
stockholders meeting held to approve the transaction. For purposes of this 
pro forma presentation, it is assumed that 6.7 million shares will be issued 
(based on a price of $33 per share of Corning Common Stock and the current 
number of Nichols common shares and options to purchase Nichols common shares 
outstanding). Pursuant to the agreement with Nichols, the maximum number of 
shares of Corning Common Stock which could be issued is 9.6 million shares 
(assuming the "floor" price of $26.50 per share of Corning Common Stock and 
exercise of all outstanding options). An increase in the number of shares to 
9.6 million shares would not materially impact the pro forma earnings per 
share presented in the Unaudited Pro Forma Combined Statements of Income. 

 Adjustments to Reflect the Offering 

(h) The pro forma adjustment to interest expense reflects the decrease in 
interest expense assuming the issuance by Corning Delaware on January 4, 
1993, of $325 million of Preferred Securities (net of an estimated $8.0 
million of underwriting commissions and expenses), and the use of the net 
proceeds thereof by Corning to retire a significant portion of the 
indebtedness incurred in connection with the Damon Transaction. 
</r.

(i) The pro forma adjustment to tax expense reflects the tax effects of the 
adjustment detailed in note (h) above. 


(j) The pro forma adjustment to dividends on preferred securities of 
subsidiaries represents the after-tax dividends payable on the $325 million 
of Preferred Securities. 



(k) The pro forma adjustment to loans payable beyond one year and preferred 
securities of subsidiaries assumes the issuance on March 27, 1994, of $325 
million of Preferred Securities (net of an estimated $8.0 million of 
underwriting commissions and expenses). 


Note 3--Earnings Per Share: 
Earnings per common share are computed by dividing net income less preferred 
dividends on Corning's Series B Preferred Stock by the weighted average of 
common shares outstanding during each period. Preferred dividends amounted to 
$2.2 million and $.5 million during the year ended January 2, 1994, and the 
twelve weeks ended March 27, 1994, respectively. 

Note 4--Costar Merger: 
In September 1993, 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. 

Note 5--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. 

Note 6--Vitro Transaction: 
On January 2, 1992, Corning entered into an alliance with Vitro, by 
transferring 49% of its consumer-housewares businesses to Vitro, in exchange 
for 49% of Vitro's consumer-products businesses and approximately $137 
million in cash. The alliance consisted of two jointly owned companies. 
Corning owned 51% of Corning Vitro and consolidated its financial statements 
and 49% of Vitro Corning and accounted for its investment under the equity 
method. 

In December 1993, Vitro and Corning reached an agreement whereby, in two 
separate transactions, Vitro purchased in December 1993, the shares of 
capital stock of Vitro Corning owned by Corning and Corning purchased in 
February 1994 the shares of capital stock of Corning Vitro held by Vitro. The 
net cost to Corning of the two transactions was $131 million. Corning and 
Vitro are continuing their consumer products alliance through cross 
distribution and supply agreements. 
<PAGE>
                   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. 

  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 all or 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 a restructuring charge of $156.0 million as
a result of costs to integrate the Damon acquisition and a planned
company-wide program to reduce assets and overhead costs during 
the next year, other special charges totaling $51.0 million and a
non-operating gain of $4.2 million. The other special charges
primarily 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 and $8.0 million of
transaction expenses related to the Costar acquisition. 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.

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 
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. The 
Settlement Agreement is subject to court approval and to withdrawal by Dow 
Corning and other defendants and plaintiffs in certain events. Corning is not 
a party to the Settlement Agreement and will not make any contributions to 
the settlement contemplated thereby. 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. As disclosed in Dow Corning's financial statements, 
this charge included the net present value of Dow Corning's best estimate 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, for a total of 
$1.24 billion, less expected insurance recoveries of $600 million. Future 
developments, including any failure of the Settlement Agreement to receive 
court approval and any withdrawal by Dow Corning and other defendants and 
plaintiffs from the Settlement Agreement, may require Dow Corning to revise 
its current estimates or record additional provisions. 

Corning does not believe that its share of any additional accounting charge 
taken by Dow Corning resulting from the breast implant litigation 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. The amount of any such 
charge would be written off against Corning's investment in Dow Corning which 
totalled $370 million at June 19, 1994. 

In early 1993, Dow Corning suspended its dividend payments to Corning and Dow 
Chemical. In 1992, Corning received from Dow Corning $43 million in 
dividends. Corning does not expect to receive dividends from Dow Corning for 
the next several years. Corning believes that it has sufficient liquidity and 
access to capital and does not believe that the suspension of these dividends 
will have a material impact on its liquidity or financial position. 

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 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 NTL for $130 million in a transaction 
accounted for as a purchase. NTL 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.

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 $52.0 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 other special charges of $43.0 million,
primarily including 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.

(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.

</TABLE>

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 the third quarter 1993, Corning recorded a charge of $207.0 million ($120.5
million after tax of $79.1 million and minority interest of $7.4 million) which
included $156.0 million of restructuring charges and $51.0 million of other
special charges.  The restructuring charges included costs to integrate the
Damon acquisition and costs of a planned company-wide restructuring program to
reduce assets and overhead costs during 1994. The other special charges 
primarily included a charge by MetPath 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, and $8 million of investment banking, legal and accounting fees and 
other transaction expenses related to the Costar acquisition.

The costs to integrate the Damon acquisition include the costs of shutting down
MetPath facilities in certain markets where duplicate MetPath and Damon
facilities existed at the time of the transaction.  These costs totaled $40.6
million and primarily included employee severance and other employee termination
benefits ($6 million), costs of exiting leased laboratory space and the
write-off of duplicate laboratory equipment ($24 million) and certain costs for
continuing employees directly related to the integration of Damon and MetPath
($3.3 million).  Management believes that the integration of Damon and MetPath
facilities should significantly reduce operating costs of the combined
companies and will be substantially complete by the end of 1994.

The costs to be incurred in the company-wide restructuring program totaled
$115.4 million and included, among other items, severance and other employee
termination benefits ($68.2 million) related to a company-wide program to
reduce employment levels (and thus operating costs), facility and other costs to
consolidate the North American packaging and worldwide Pyroceram manufacturing 
operations in the Consumer Products segment ($23.6 million), facility and other
costs to restructure or close several environmental and pharmaceutical testing 
facilities ($9.1 million), consulting fees associated with company-wide in-depth
studies aimed at re-engineering the organization and operating practices of the 
Company ($11.8 million) and certain costs for continuing employees directly 
related to the restructuring plans ($3.4 million).  Management believes that the
company-wide restructuring program will significantly reduce operating costs and
will be substantially complete by the end of 1994.  The Company's re-engineering
studies are expected to be complete in the first half of 1995.  It is possible 
that these studies will result in additional employee terminations, asset 
write-offs and other cost reduction activities beginning in late 1994 or in 
1995.  It is currently not possible to estimate the costs or benefits of these
terminations, write-offs or other activities.

The 1993 restructuring and integration charges included severance and other
termination benefits related to approximately 1,600 employees.  Employee
reductions primarily include employees at various MetPath laboratory locations,
salaried employees at Corning Consumer Products Company (formerly known as
Corning Vitro Corporation) and salaried employees in various line, research and
staff organizations throughout the Company where business conditions require
reduced staff levels.  At the end of the second quarter 1994, approximately
1,100 employees across the Company had been terminated or notified of their
termination and approximately $19.6 million of the $74.2 million severance and
other termination benefits had been paid.

The 1993 restructuring and integration charges included $29.3 million of asset
write-offs and $126.7 million of future cash expenditures of which
approximately $5.1 million was spent in 1993 and $86.4 million, $31.2 million
and $4.0 million is expected to be spent in 1994, 1995 and future years,
respectively.  Corning management believes these costs will be financed with
cash from operations and does not anticipate any significant impact on its
liquidity as a result of the restructuring plan.


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 all or 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 more than 50 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 
Life Sciences Inc. ("CLSI"), to better manage the development of its business 
in this rapidly growing area. Today CLSI, through subsidiaries and 
affiliates, operates more than 50 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 June 7, 1994, Corning acquired 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. 

On June 1, 1994, Corning signed a definitive agreement to acquire all of the 
outstanding shares of the capital stock of Nichols in a transaction to be 
accounted for as a pooling of interests. Under the terms 
of the agreement, Corning will exchange newly issued and registered shares of 
Corning Common Stock with a value equal to up to $13 for each share of the 
capital stock of Nichols. Using an assumed price of $33 per share of Corning 
Common Stock and the number of shares of, and options to purchase, the 
capital stock of Nichols presently outstanding, approximately 6.7 million 
shares of Corning Common Stock and options to purchase approximately 1 
million shares of Corning Common Stock will be issued in the transaction. 
Substantially all of the options to purchase shares of Corning Common Stock 
will be exercisable immediately following the closing of the transaction. In 
no event will more than 9.6 million shares of Corning Common Stock be issued 
and reserved for the exercise of options granted in connection with such 
transaction. 

For a discussion of the registration rights granted to the stockholders of 
Maryland Medical and the registration of the shares of Corning Common Stock 
to be issued in the Nichols transaction, see "Description of Corning Capital 
Stock--Common Stock Eligible for Future Sale." 

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. On June 28, 1994, Corning and International Technology created a 
jointly owned company to which Corning transferred the net assets of 
MetPath's environmental testing laboratory business and International 
Technology transferred the assets of its IT Analytical Services business. 
Corning and International Technology each own 50 percent of the company. 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 

Creation of Environmental Testing Services Company. On June 28, 1994, Corning 
and International Technology created a jointly owned company to which Corning 
transferred the net assets of its environmental testing laboratory business 
and International Technology transferred the assets of its IT Analytical 
Services business. Corning and International Technology each will own 50 
percent of the company. 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 Clinical Laboratory Testing Businesses. On June 7, 1994, 
Corning acquired all of the outstanding shares of Maryland Medical for 
approximately 4.5 million shares of Corning Common Stock in a pooling of 
interests transaction. 

On June 1, 1994, Corning signed a definitive agreement to acquire all of the 
outstanding shares of the capital stock of Nichols in a transaction to be 
accounted for as a pooling of interests. Under the terms of the agreement, 
Corning will exchange newly issued and registered shares of Corning Common 
Stock with a value equal to up to $13 for each share of the capital stock of 
Nichols. Using an assumed price of $33 per share of Corning Common Stock and 
the number of shares of, and options to purchase, the capital stock of 
Nichols presently outstanding, approximately 6.7 million shares of Corning 
Common Stock and options to purchase approximately 1 million shares of 
Corning Common Stock will be issued in the transaction. Substantially all of 
the options to purchase shares of Corning Common Stock will be exercisable 
immediately following the closing of the transaction. In no event will more 
than 9.6 million shares of Corning Common Stock be issued and reserved for 
the exercise of options granted in connection with such transaction. The 
final exchange ratio of shares of Corning Common Stock for shares of Nichols 
capital stock will be determined by the price of Corning Common Stock during 
a 10-day trading period prior to the date of the Nichols stockholders meeting 
held to approve the transaction. The transaction is subject to regulatory 
approval and is expected to close in the second half of 1994. 

Corning's consolidated financial statements for periods prior to these 
transactions will not be restated since the acquisitions are not material to 
Corning's financial position or results of operations. Corning will likely 
record a one-time charge of up to $10 million after-tax in the third quarter 
for transaction costs associated with these acquisitions and may possibly 
record an additional one-time charge of up to $25 million after-tax in the 
second half of 1994 for the integration of the Nichols and Maryland Medical 
operations into MetPath. 

For a discussion of the registration rights granted to the stockholders of 
Maryland Medical and the registration of the shares of Corning Common Stock 
to be issued in the Nichols transaction, see "Description of Corning Capital 
Stock--Common Stock Eligible for Future Sale." 

Sale of Parkersburg Plant. In May 1994, Corning sold its Parkersburg, W.Va., 
glass-tubing products plant to Schott Corporation, a subsidiary of the Schott 
Group, for $57 million and decided to exit several minor product lines in the 
specialty materials segment. The net gain from these transactions is not 
material. 

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 
were used to retire a portion of the debt incurred in connection with the 
acquisition of Damon in August 1993. 

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, some of which are on 
appeal. 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 July 8, 1994, Dow Corning has 
been named in 45 purported breast implant product liability class action 
lawsuits and approximately 15,900 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 the Settlement Agreement. The 
Settlement Agreement is subject to court approval and to withdrawal by Dow 
Corning and other defendants and plaintiffs. 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 is not a party to the Settlement Agreement and will not 
make any contribution to the settlement contemplated thereby. 

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. Unless the current schedule 
is extended by the Court, Dow Corning would expect to decide whether or not to 
exercise its option to withdraw from the Settlement Agreement by mid-August 
1994. 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. 


On July 12, 1994, Reuters Information Services, Inc. published a report 
indicating that results of preliminary experiments by researchers at the U.S.
National Cancer Institute showed that silicon gel from Dow Corning breast 
implants injected into genetically susceptible mice causes a form of cancer.
The Reuters report indicates that this study is to be published in the July 
20, 1994 edition of the Journal of the National Cancer Institute. Dow Corning
has not yet had an opportunity to review this study or assess the study's 
potential impact on its financial condition or results of operations.


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 Investigations. 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. MetPath also received in May 1994 two subpoenas from the Inspector 
General concerning, in one case, an investigation into billings for tests not 
performed or reported for which MetPath had voluntarily made corrective 
payments in 1993 and, in the other, an investigation into whether separate 
billings for tests which should have been grouped together had occurred. In 
addition, a federal grand jury in New Jersey is investigating the billings 
for tests not performed or reported. 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, with respect to which the underwriters 
have been dismissed, 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 and any interests of any Special General Partner) 
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 so its initial capital contributions
are equal to at least 21% of all the capital contributed to Corning Delaware. 
The General Partner will invest 99% of the total contributions in Corning 
Delaware in the Subordinated Debentures and the remaining 1% in Eligible 
Investments as provided in the Amended and Restated Limited Partnership 
Agreement (the "Limited Partnership Agreement"). Corning Delaware will 
exist for a maximum term of 45 years, unless earlier dissolved. The 
Limited Partnership Agreement of Corning Delaware provides that the 
General Partner will have liability for the debts and obligations of 
Corning Delaware (including certain 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 
personally 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 in the Subordinated Debentures and Eligible Investments, as described 
above. 


                      DESCRIPTION OF SECURITIES OFFERED 
   
The securities offered hereby are 6% 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 through Corning Delaware into shares of Corning Common Stock at an 
initial conversion rate of 1.2821 shares of Corning Common Stock for 
each $50 principal amount of Subordinated Debentures (equivalent to a 
conversion rate of 1.2821 shares of Corning Common Stock for each Preferred 
Security), subject to adjustment in certain circumstances. The Preferred 
Securities are guaranteed, to the extent described herein, by Corning as to 
dividends, the Redemption Price 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 the 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 Partnership Agreement, 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 (and any interests of any Special General Partner) will be owned 
directly by Corning at all times while the Preferred Securities are 
outstanding. 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 
other partnership interests in Corning Delaware. The Limited Partnership 
Agreement does not permit the issuance of other partnership interests without 
the prior approval of holders of not less than 66-2/3% of the aggregate 
liquidation preference of the Preferred Securities then outstanding. 

Holders of Preferred Securities will have no preemptive rights. 

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

  Dividends 
   
Holders of the Preferred Securities will be entitled to receive cumulative 
cash distributions from Corning Delaware, accruing from July 21, 1994 and 
payable monthly in arrears on the last day of each calendar month of each 
year, commencing July 31, 1994 ("dividends"). The dividends payable on 
each Preferred Security will be fixed at a rate per annum of $3.00 or 
6% 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. 
    
Dividends on the Preferred Securities must be declared monthly and paid on 
the last day of each calendar month to the extent that Corning Delaware has 
funds legally available for the payment of such dividends and cash on hand 
sufficient to make 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 "Investment 
Considerations--Option to Extend Payment Periods", "--Additional Dividends" 
and "--Option to Extend Interest Payment Period." The failure of holders of 
Preferred Securities 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 one share of Corning 
Series C Preferred Stock for two Preferred Securities). See "--Optional 
Exchange for Corning Series C Preferred Stock." 

If a Tax Event occurs, then all dividends and distributions (including 
distributions to the General Partner) shall be reduced by Additional Taxes, 
commencing on the date that is the earlier of (i) three months after the date 
of notice of such Tax Event and (ii) the date of a vote taken at a special 
partnership meeting (or, in lieu of such a meeting, the date of written 
consent) by the holders of the Preferred Securities on the matter of whether 
to cause the exchange of all Preferred Securities for shares of Corning 
Series C Preferred Stock (such earlier date being referred to herein as the 
"Tax Event Date"). Prior to the Tax Event 

Date, no reduction will be made on account of Additional Taxes and any 
Additional Taxes will be paid by Corning. 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 on or after the date of this Prospectus, 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), (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 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, or (ii) 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, except for United States 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 Tax Event 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 or Chicago are authorized or obligated 
by law or executive order to close. 

Additional Dividends 

Corning Delaware shall be required to declare and pay additional dividends at 
a rate of 6% per annum on the Preferred Securities upon any dividend 
arrearages in respect of the Preferred Securities in order to provide, in 
effect, monthly compounding on such dividend arrearages. (The amounts payable 
to effect such monthly compounding on dividend arrearages in respect of the 
Preferred Securities being referred to herein as "Additional Dividends"). 

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, including any Additional Dividends thereon, 
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 August 5, 
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 35 nor more than 
60 days' prior notice, at any time or from time to time, during the 
twelve-month periods beginning on August 5 in each of the following 
years at the redemption price (expressed as a percentage of the liquidation 
preference) indicated below, plus accumulated and unpaid dividends (the 
"Redemption Price"):

August 5, 2004 and thereafter                 100.0 
</TABLE>
    
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 there is a redemption (optional or mandatory) of 
Preferred Securities after the Tax Event Date, then the Redemption Price for 
such Preferred Securities will be reduced by the amount of Additional Taxes, if 
any, that are attributable to such redemption of such Preferred Securities. 


Mandatory Redemption 

Upon repayment or prepayment by Corning of the Subordinated Debentures, 
including as a result of the acceleration of the Subordinated Debentures upon 
the occurrence of an "Event of Default" described under "Description of 
Securities Offered--Description of the Subordinated Debentures--Events of 
Default", 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 (optional or mandatory) 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 35 nor more than 60 days prior to the date fixed for 
redemption thereof. If Corning Delaware gives a notice of redemption, then 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") or the Paying and Conversion Agent, as the 
case may be, and give DTC or the Paying and Conversion Agent, as the case may 
be, 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 or the Paying and 
Conversion Agent, as the case may be, 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 the Preferred Securities called for redemption will continue to accumulate 
at the then applicable rate, from the original redemption date to the date 
that the Redemption Price is actually paid and the holders of such Preferred 
Securities may exercise all of their rights as holders of the Preferred 
Securities. 

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. 

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 rate of 1.2821 shares of Corning 
Common Stock for each Preferred Security (equivalent to a conversion price of 
$39.00 per share of Corning Common Stock), subject to adjustment as 
described under "--Conversion Price Adjustments" 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 an equivalent 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. Except as provided in the immediately preceding sentence, 
Corning Delaware will make no payment or allowance for accumulated and unpaid 
dividends, whether or not in arrears, on converted Preferred Securities. 
Corning will make no payment or allowance for dividends on the shares of 
Corning Common Stock issued upon such conversion except with respect to 
dividends or distributions as of record dates subsequent to 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 such fractional interest will be paid in 
cash. 

Conversion Price Adjustments--General. 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 in the form of evidences 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 regular 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 annualized per share amount thereof 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. 

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 Corning Common Stock (or securities convertible into 
or exchangeable for Corning Common 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 anti-dilution provisions, 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. 

Conversion Price Adjustments--Merger, Consolidation or Sale of Assets of 
Corning. 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, as a result of which shares of Corning 
Common Stock shall be converted into the right (i) in the case of any 
Transaction other than a Transaction involving a Common Stock Fundamental 
Change (as defined below) 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, or (ii) in the case of a Transaction 
involving a Common Stock Fundamental Change to receive common stock of the 
kind received by holders of Corning Common Stock (but in each case after 
giving effect to any adjustment discussed below relating to a Fundamental 
Change if such Transaction constitutes a Fundamental Change). 

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, 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. 

The conversion price in the case of any Transaction involving a Fundamental 
Change will be adjusted 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 August 5, 1998, an amount per Preferred Security 
of $53.00 (for the twelve month period ended August 5, 1995), $52.70 (for 
the twelve month period ended August 5, 1996), $52.40 (for the twelve 
month period ended August 5, 1997) and $52.10 (for the twelve month period 
ended August 5, 1998)); 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 only 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 prior to 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 and would 
no longer be convertible into securities whose value would vary depending on 
the future prospects of Corning 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 $21.42 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 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 equal to the then 
current Redemption Price per Preferred Security (or, for periods prior to 
August 5, 1998, the amounts per Preferred Security for such periods set 
forth in clause (i) above with respect to conversion prices for Non-Stock 
Fundamental Changes). 
    
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. 

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 General 
Partner to appropriately reflect any of the events referred to in clauses (i) 
through (vi) of the first paragraph under "--Conversion Price 
Adjustments--General." 

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 General Partner 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 General Partner to appropriately reflect any of the events 
referred to in clauses (i) through (vi) of the first paragraph under 
"--Conversion Price Adjustments--General." 
   
The term "Reference Market Price" shall initially mean $21.42 (which is an 
amount equal to 66-2/3% of the reported last sale price for the Corning 
Common Stock on the NYSE on July 13, 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 $21.42 
to the initial conversion price of the Preferred Securities. 
Optional Exchange for Corning Series C Preferred Stock 
    
Upon the occurrence of an Exchange Event (as defined below), the holders of 
not less than 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 in 
exchange for the Preferred Securities. 

The Corning Series C Preferred Stock issued upon any such exchange will have 
terms substantially similar 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 
Dividends) on the Preferred Securities that are not paid at the time of 
making an Exchange Election shall be treated as accrued and unpaid dividends 
on the Corning Series C Preferred Stock. For a discussion of the taxation of 
such an exchange to holders, including the possibility that holders who 
exchange their Preferred Securities for Corning Series C Preferred Stock may 
be subject to additional income tax to the extent accrued but unpaid interest 
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, see "Certain Federal Income Tax 
Considerations--Exchange of Preferred Securities for Corning Series C 
Preferred Stock." 

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 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. If the General Partner fails to convene such Exchange Election Meeting 
within such 30-day period, the holders of not less than 10% of the aggregate 
liquidation preference 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 a Tax Event, Corning 
Delaware will continue to pay dividends on the Preferred Securities without 
adjustment for Additional Taxes until the Tax Event 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), including any Additional Dividends thereon, to the 
date of payment (the "Liquidation Distribution") out of the assets of Corning 
Delaware legally available for distribution to partners prior to any 
distribution by Corning Delaware on its other partnership interests. 

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) any bankruptcy, 
dissolution or insolvency of the General Partner; (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 or merge with or into, 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 or merge with or into 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 or consolidation 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 or consolidation does not cause the 
Preferred Securities (including any Successor Securities) to be downgraded by 
any nationally recognized statistical rating organization, (v) such merger or 
consolidation 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 or consolidation 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 or 
consolidation, Corning and such successor entity will be in compliance with 
the 1940 Act without registering thereunder as an investment company and (z) 
such merger or consolidation 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 (other than as a result of a 
determination by Corning to defer interest payments on the Subordinated 
Debentures as described under "Description of Securities Offered--Description 
of the Subordinated Debentures--Option to Extend Interest Payment Period"); 
(ii) an Event of Default (as defined under "Description of Securities 
Offered--Description of the Subordinated Debentures--Events of Default") 
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, upon the affirmative vote of not less 
than a majority in aggregate liquidation preference of the Preferred 
Securities then outstanding, 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 
pur- 

poses 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 not less than 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 Event of Default or default, 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 additional limited partnership interests in 
Corning Delaware), 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 not less than 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. 

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 partnership interests in Corning Delaware other than the interests 
represented by the Preferred Securities, the interests of the General Partner 
and the interests of any Special General Partner. 

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 (as 
defined under "Description of Securities Offered--Description of the 
Subordinated Debentures"), or exercising any trust or power conferred on the 
Special General Partner 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 the Special General Partner or by 
a vote of Preferred Securities, without the approval of the holders of 
Preferred Securities representing not less than 66-2/3% 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. 
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 upon a resignation of DTC, upon the occurrence of an Event 
of Default under the Subordinated Debentures or upon a decision by Corning 
Delaware to discontinue the book-entry system for the Preferred Securities. 

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 cus 
tomary 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. 

Transfer Agent, Registrar, Paying and Conversion Agent 

Harris Trust and Savings Bank will act as Transfer Agent, Registrar and 
Paying and Conversion 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 may require) in respect of any tax or 
other government charges which may be imposed in relation to it. 

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 through Corning Delaware 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, 3,250,000 shares (3,737,500 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 are 
substantially similar to those of the Preferred Securities with the following 
principal exceptions: 

  (a) Accumulated and unpaid dividends (including any Additional Dividends 
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 (including for this purpose any arrearage with 
respect to the Preferred Securities), 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 Junior Stock (as defined 
under "--Description of the Guarantee--Subordination") of Corning ranking 
junior to the Corning Series C Preferred Stock; and 

  (d) The Corning Series C Preferred Stock 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 (as defined below under 
"Description of Corning Capital Stock--Series Preferred 
Stock") with respect to the payment of dividends and amounts on liquidation, 
dissolution and winding-up. 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 and any other pari passu 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 not less than 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 Dividends 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. 

If Corning fails to make interest payments on the Subordinated Debentures 
purchased by Corning Delaware, Corning Delaware will have insufficient funds 
to pay dividends on the Preferred Securities. The Guarantee does not cover 
payment of dividends when Corning Delaware does not have sufficient funds to 
pay such dividends.

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. 

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 Junior Stock (as defined below under "--Subordination") 
(other than as a result of a reclassification of Junior Stock or the exchange 
or conversion of one class or series of Junior Stock for another class or 
series of Junior 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 has exercised its option to 
extend the interest payment period on the Subordinated Debentures and such 
extension is continuing, 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. When 
dividends are not paid in full, all dividends declared upon the Preferred 
Securities and all dividends declared upon any Pari Passu Stock shall be 
declared ratably in proportion to the respective amounts of dividends 
accumulated and unpaid on the Preferred Securities and accumulated and unpaid 
on such Pari Passu Stock. "Pari Passu Stock" means Corning's Series B 
Preferred Stock, and any guarantee now or hereafter entered into by Corning 
in respect of any preferred or preference stock of any affiliate of Corning, 
and any other class or series of preferred stock of Corning, ranking as to 
the payment of dividends and amounts upon liquidation, dissolution and 
winding-up on a parity with the Series B Preferred Stock. 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, except as permitted in the Limited Partnership 
Agreement, (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, 
except as permitted in the Limited Partnership Agreement, (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, with any guarantee now or hereafter 
entered into by Corning in respect of any preferred or preference stock of 
any affiliate of Corning and any other class or series of Corning preferred 
stock ranking as to the payment of dividends and amounts upon liquidation, 
dissolution and winding up on a parity with the Series B Preferred Stock and 
(iii) senior to Corning Common Stock, the Series A Preferred Stock and any 
other class or series of capital stock issued by Corning or any of its 
affiliates which by its express terms ranks junior in the payment of 
dividends and amounts on liquidation, dissolution, and winding-up to the 
Preferred Securities ("Junior Stock"). 

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 complying with the provisions 
under "--Consolidation, Merger or Sale of Assets" below. 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 all of 
such holder's Preferred Securities 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. 

Consolidation, Merger or Sale of Assets 

The Guarantee provides that Corning may merge or consolidate with or into 
another entity, may permit another entity to merge or consolidate with or 
into Corning and may sell, transfer or lease all or substantially all of its 
assets to another entity 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, consolidation, sale, transfer or 
lease and (ii) the survivor of such merger or consolidation or entity to 
which Corning's assets are sold, transferred or leased 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 the 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 July 21, 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 August 5, 1998, during the twelve-month 
periods beginning on August 5 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): 

<TABLE>

August 5, 2004 and thereafter            100.0
</TABLE>
    
Interest 
   
The Subordinated Debentures will bear interest at the rate of 6% 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 July 31, 1994. Interest will compound monthly and will accrue 
at the annual rate of 6% on any interest installment not paid monthly or 
when otherwise 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 and 
at the end of which period Corning shall pay all interest then accrued and 
unpaid (together with Additional 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 Junior Stock (other than as a result of a reclassification of Junior 
Stock or the exchange or conversion of one class or series of Junior Stock 
for another class or series of Junior Stock) or make any guarantee payments 
with respect to the foregoing (other than payments under the Guarantee or 
dividends or guarantee payments to Corning). 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 any interest upon interest that has not been 
paid on the Subordinated Debentures monthly. Accordingly, in such 
circumstance, Corning will pay interest upon interest in order to provide for 
monthly compounding on the Subordinated Debentures (the amounts of interest 
payable to effect monthly compounding on the Subordinated Debentures being 
referred to herein as "Additional Interest"). 

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 trade creditors. 

Upon any payment or distribution of assets to creditors upon any liquidation, 
dissolution, winding-up, reorganization, assignment for the benefit of 
creditors, marshalling of assets or any bankruptcy, insolvency or similar 
proceedings of Corning, the holders of all Senior Indebtedness will first be 
entitled to receive payment in full of all amounts due thereon before any 
payment will be made in respect of the principal of or premium, if any, or 
interest on the Subordinated Debentures. In the event of the acceleration of 
the maturity of the Subordinated Debentures, the holders of all Senior 
Indebtedness will first be entitled to receive payment in full of all amounts 
due thereon before any payment will be made upon the principal of or premium, 
if any, or interest on the Subordinated Debentures. No payments on account of 
principal, premium, if any, or interest in respect of the Subordinated 
Debentures may be made if there shall have occurred and be continuing a 
default in any payment with respect to Senior Indebtedness, or an event of 
default with respect to any Senior Indebtedness permitting the holders 
thereof to accelerate the maturity thereof. 

By reason of such subordination, in the event of any proceeding of the type 
described in the preceding paragraph involving Corning, creditors of Corning 
who are holders of Senior Indebtedness and general unsecured creditors of 
Corning may recover more, ratably, than Corning Delaware. 

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 June 19, 1994, Senior Indebtedness of Corning aggregated approximately 
$1.9 billion. The Fiscal Agency Agreement does not limit Corning's ability to 
incur Senior Indebtedness. 

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 Junior 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 Limited Partnership 
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 as General Parter, (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 direct ownership of all partnership 
interests of Corning Delaware other than the Preferred Securities and any 
Special General Partnership Interest, (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 deliver shares of Corning Series C Preferred Stock or 
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 : 

  (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 deliver shares of Corning Series C Preferred 
Stock or 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, or any subsequent holder of the Subordinated 
Debentures, 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 accrued 
interest (including any Additional Interest) thereon 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 $50 principal amount of the 
Subordinated Debentures for every Preferred Security 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 
one share of Corning Series C Preferred Stock for each $100 principal amount 
of the Subordinated Debentures. Accrued and unpaid interest (including 
Additional Interest) on the Subordinated Debentures will 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 any 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 have 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 June 23, 
1994, 213,575,956 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. 

 Common Stock Eligible for Future Sale 
In connection with the acquisition by Corning on June 7, 1994 of all of the 
outstanding shares of Maryland Medical for approximately 4.5 million shares 
of Corning Common Stock, Corning granted to the stockholders of Maryland 
Medical registration rights for such shares of Corning Common Stock. Pursuant 
to such rights, Corning is required to file a registration statement covering 
all 4.5 million shares of Corning Common Stock no later than 90 days after 
the written request of the designated representative of such stockholders. As 
of July 13, 1994, no such request had been received by Corning. 

On June 1, 1994 Corning signed a definitive agreement to acquire all of the 
outstanding shares of the capital stock of Nichols in a transaction to be 
accounted for as a pooling of interests. Under the terms of the agreement, 
Corning will exchange newly issued and registered shares of Corning Common 
Stock with a value equal to up to $13 for each share of the capital stock of 
Nichols outstanding. Using an assumed price of $33 per share of Corning 
Common Stock and the number of shares of the capital stock of Nichols 
presently outstanding, approximately 6.7 million shares of Corning Common 
Stock will be issued in such exchange. The final exchange ratio of shares of 
Corning Common Stock for shares of Nichols capital stock will be determined 
by the price of Corning Common Stock during the 10-day trading period ending 
on the fifth trading day prior to the date of the Nichols stockholders 
meeting held to approve the transaction. In no event will more than 8.4 
million shares of Corning Common Stock be issued in exchange for the 
outstanding shares of the capital stock of Nichols. 

At the closing of the Nichols transaction, outstanding options to purchase 
the capital stock of Nichols will be converted to options to purchase Corning 
Common Stock in accordance with the final exchange ratio. At a value of $13 
per share of capital stock of Nichols, substantially all of the options to 
purchase the capital stock of Nichols are "in the money." Using an assumed 
price of $33 per share of Corning Common Stock and the number of options to 
purchase the capital stock of Nichols presently outstanding, approximately 
1.0 million shares of Corning Common Stock will be reserved for issuance upon 
the exercise of such options. Substantially all of such options to purchase 
Corning Common Stock will be exercisable immediately following the closing of 
the transaction. In no event will more than 1.2 million shares of Corning 
Common Stock be issued upon the exercise of outstanding options. Corning 
believes that approximately 85% of the shares of Corning Common Stock to be 
issued in the Nichols transaction will be freely transferable upon 
consummation of the acquisition. 

The Nichols transaction is subject to regulatory approval and is expected to 
close in the second half of 1994. 
   
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 (the "Series A Preferred Stock"), 
500,000 shares of Series Preferred Stock as Series B Preferred Stock (the 
"Series B Preferred Stock"), and 3,737,500 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 
ranks pari passu with the Corning Series C Preferred Stock with respect to 
the payment of dividends and amounts on liquidation, dissolution and 
winding-up. See "Description of Securities Offered--Series C 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: 

<TABLE>
<CAPTION>
 During the Twelve- 
Month Period                                             Price Per

1993                                                       $104.00 
1994                                                       $103.00 
1995                                                       $102.00 
1996                                                       $101.00 
</TABLE>

  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 
In the opinion of Shearman & Sterling, special federal income tax counsel to 
Corning and Corning Delaware, the following discussion accurately describes, 
subject to the limitations stated herein, the material federal income tax 
considerations relevant to the purchase, ownership and disposition of the 
Preferred Securities. This discussion is a summary that 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. Further, while the following summary reflects the opinion of 
Shearman & Sterling, an opinion of counsel 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 Subordinated Debentures, 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 and perhaps without a dividends-received deduction 
with respect to such dividends. 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 holder of a Preferred Security 
may be allocated a larger or smaller amount of Corning Delaware's 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 Corning has 
an option, 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 Guarantee. If the IRS were 
successful in requiring such 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 by a holder will equal the amount paid by such holder
for the Preferred Securities, plus the share of partnership income 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 August 5, 2004 and Corning Delaware will 
pay a corresponding redemption premium to holders of Preferred Securities 
whose Preferred Securities are redeemed before August 5, 2004. Corning 
Delaware will recognize capital gain on a prepayment 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 subsequently 
redeemed by Corning Delaware, and the allocated gain should increase the 
holder's adjusted tax basis in these 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 subsequent redemption of the holder's Preferred Securities. 


Corning Delaware will allocate income to holders of record 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, through Corning Delaware, for Corning Common Stock effective on a 
date other than an interest payment date (generally the last day of a calendar
month) 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 generally 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 a 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 by Corning 
Delaware to a holder in lieu of a fractional share interest, 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 
taxable 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 a complete 
liquidation of Corning Delaware. If Corning Delaware is taxed as a 
partnership, Corning Delaware's subsequent distribution of the Corning Series 
C Preferred 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 for 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 to both 
Corning Delaware and the 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. 

In addition, if Corning exercises its option to extend interest payment 
periods under the Subordinated Debentures for more than fifteen months or if 
a Tax Event occurs, 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, under the 
Limited Partnership Agreement, to furnish such Schedule K-1 as soon as 
practicable following the end of the taxable year, but in any event prior to 
March 31st of each succeeding year (assuming, as anticipated, that Corning 
Delaware's taxable year is a calendar 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 such 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 tax 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 tax 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 United States 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 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 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 this 
legislation, a large partnership would not be deemed to terminate 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.

</TABLE>
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 $.675 per Preferred Security. The Underwriters 
may allow, and such dealers may reallow, a concession not in excess of $.225
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 $ 1.125 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 975,000 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 6,500,000 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, acquisitions or 
similar transactions (so long as the holders agree to this restriction), 
(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 or 
(g) Corning Common Stock issued pursuant to the Nichols transaction. 
    
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. 

                                   EXPERTS 

The consolidated financial statements of Corning and of Dow Corning 
incorporated in this Prospectus by reference to Corning's 1993 Annual Report
