Corning Delaware 

% 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 5,500,000    % Convertible Monthly Income Preferred Securities (the 
"Preferred Securities") are being issued by Corning Delaware, L.P. ("Corning 
Delaware"), a Delaware limited partnership. All of the partnership interests 
in Corning Delaware, other than the limited partnership interests represented 
by the Preferred Securities, are owned by Corning Incorporated, a New York 
corporation ("Corning" or the "Company"), which is the general partner in 
Corning Delaware. The Preferred Securities will have a preference over all 
other partnership interests of Corning Delaware with respect to cash 
distributions and amounts payable on liquidation. 
    
   
Holders of the Preferred Securities will be entitled to receive cumulative 
cash distributions from Corning Delaware, at an annual rate of    % of the 
liquidation preference of $50 per Preferred Security, accruing from       , 
1994 and payable monthly in arrears on the last day of each calendar month of 
each year, commencing        , 1994 ("dividends"). See "Description of 
Securities Offered--Preferred Securities--Dividends." 
    

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.

(1) Corning Delaware and Corning have agreed to indemnify the Underwriters 
against certain liabilities, including liabilities under the Securities Act 
of 1933, as amended. See "Underwriting." 

(2) In view of the fact that the proceeds of the sale of the Preferred 
Securities will ultimately be used by Corning Delaware to purchase 
convertible subordinated debentures of Corning, the Underwriting Agreement 
provides that Corning will pay to the Underwriters, as compensation 
("Underwriters' Compensation"), $      per Preferred Security (or $    in the 
aggregate). See "Underwriting." 

(3) Expenses of the offering which are payable by Corning are estimated to be 
$    . 

   
(4) Corning Delaware and Corning have granted the Underwriters an option for 
30 days to purchase up to an additional 825,000 Preferred Securities at the 
initial public offering price per share, solely to cover over-allotments. 
Corning will pay to the Underwriters, as Underwriters' Compensation, $ 
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 $, $and $, 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           , 1994.

                 The date of this Prospectus is       , 1994. 

<PAGE>
(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   shares of Corning Common Stock for each Preferred 
Security (equivalent to a conversion price of $   per share of Corning Common 
Stock), subject to adjustment in certain circumstances. See "Description of 
Securities Offered--Preferred Securities--Conversion Rights." The last 
reported sale price of Corning Common Stock, which is listed under the symbol 
"GLW" on the New York Stock Exchange, on June 24, 1994 was $31.25 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 June   , 1998, at the redemption prices set 
forth herein, together with accumulated and unpaid dividends to the date 
fixed for redemption. The Preferred Securities are subject to mandatory 
redemption on the 30th anniversary of the date of original issuance. See 
"Description of Securities Offered--Preferred Securities--Optional 
Redemption" and "--Mandatory Redemption." 
    

   
Corning will 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."

                             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 June 27, 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. 
    


                                 THE OFFERING 
   
<TABLE>
<CAPTION>
<S>                        <S>
Securities Offered         5,500,000 of Corning Delaware's   % Convertible Monthly Income Preferred 
                           Securities, liquidation preference of $50 per security. Additionally, Corning 
                           Delaware and Corning have granted the Underwriters an option for 30 days to 
                           purchase up to an additional 825,000 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        , 1994 
                           and will be payable at the annual rate of   % of the liquidation preference 
                           of $50 per Preferred Security. Dividends will be paid monthly in arrears on 
                           the last day of each calendar month, commencing       , 1994. The proceeds from 
                           the offering of the Preferred Securities will be invested in the Subordinated 
                           Debentures. Interest payment periods on the Subordinated Debentures are monthly 
                           but may be extended from time to time by Corning for up to 60 months, in which 
                           event Corning Delaware would be unable to make monthly dividend payments on 
                           the Preferred Securities during the period of any such extension. During such 
                           period, interest on the Subordinated Debentures and dividends on the Preferred 
                           Securities will compound monthly. The failure of holders of the Preferred Securities 
                           to receive dividends in full for 15 consecutive months 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        shares of Corning Common Stock for each Preferred Security 
                           (equivalent to a conversion price of $     per share of Corning Common Stock), 
                           subject to adjustment in certain circumstances. Upon receiving an irrevocable 
                           notice by a holder of a Preferred Security to exercise its conversion right, 
                           Corning Delaware, on behalf of such holder, will exercise its option to convert 
                           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      , 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    % 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       , 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 $           ($        if the Underwriters' 
over-allotment option is exercised in full) to retire a significant portion 
of the debt incurred in the 1993 acquisition of Damon. The Damon debt bears a 
variable interest rate based on the London Interbank Offered Rate and matures 
on December 31, 1995. For information concerning the Damon transaction, see 
"Business of Corning--Laboratory Services." 

                          INVESTMENT CONSIDERATIONS 

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

Subordinate Obligations Under Guarantee and Subordinated Debentures 

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

Option to Extend Payment Periods 

   
Corning has the right to extend interest payment periods on the Subordinated 
Debentures for up to 60 months, and, as a consequence, monthly dividends on 
the Preferred Securities would be deferred (but will continue to compound 
monthly) during any such extended interest payment period. In the event that 
Corning exercises this right, Corning may not declare dividends on any shares 
of 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 charge of $36.5 million ($22.0 million after tax) to reflect 
the settlement and related legal expenses incurred in the compromise 
agreement between MetPath and the Civil Division of the Department of 
Justice; and a restructuring charge totaling $170.5 million ($98.5 million 
after tax and minority interest) as a result of costs to integrate the Damon 
and Costar acquisitions and a planned company-wide restructuring program 
announced October 6, 1993 to reduce overhead costs during 1994. 
Corning also recorded a $203.1 million reduction in equity earnings as a 
result of a charge taken by Dow Corning related to breast-implant litigation 
and a $9.5 million reduction in equity earnings as a result of a 
restructuring charge taken by Vitro Corning. 

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

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

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

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

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

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

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

          CORNING UNAUDITED PRO FORMA COMBINED 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 $275 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 $47.1 million related to closing MetPath facilities as 
a result of the integration of Damon and MetPath and $7.9 million of Costar 
transaction costs recorded in Corning's results for the year ended January 2, 
1994. 

(c) The pro forma adjustment to interest expense represents the interest on 
the debt incurred in connection with the Damon transaction and the Other 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 $275 million of Preferred Securities (net of an estimated $6.8 
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. 

(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 $275 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 $275 
million of Preferred Securities (net of an estimated $6.8 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.

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

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

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

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

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

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

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

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

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

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

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

  Liquidity and Capital Resources 
Corning's working capital of $452.5 million at March 27, 1994 was relatively 
unchanged from $451.4 million at the end of 1993. The ratio of current assets 
to current liabilities of 1.4 was also unchanged from 
year-end 1993. Corning's long-term debt as a percentage of total capital was 
42% at the end of the first quarter compared to 45% at year-end 1993. The 
improvement in this ratio is due primarily to the issuance of common stock in 
February 1994. Corning intends to repay a significant portion of the 
remaining $400 million Damon acquisition debt with the proceeds from the sale 
of the Damon laboratories in California and the net proceeds from this 
Offering. 

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

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

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

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

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

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

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

In 1992, earnings from consolidated operations increased 12% over 1991 with 
the growth led by the Communications and Laboratory Services segments. Equity 
earnings in 1992 declined substantially from 1991 levels due to non-recurring 
charges and reduced operating earnings at Dow Corning and losses at both 
Vitro Corning and Unilab. 
Segment Overview 
In the following discussion, the sales and earnings of Corning's equity 
affiliates are discussed in terms of the Company's four industry segments.

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.

</TABLE>

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

Consolidated operations: 

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

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

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

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

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

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

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

Outlook: 

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

FAS 106 which totaled $6.3 million in 1992. 

(3) Includes $46.5 million and $63.3 million of restructuring charges in 1993 
and 1992, respectively. 

Consolidated operations: 

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

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

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

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

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

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

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

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

Equity earnings: 

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

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

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

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

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

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

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

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

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

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

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

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

  Environment 
Corning has been named by the Environmental Protection Agency under the 
Superfund Act, or by state governments under similar state laws, as a 
potentially responsible party for 22 hazardous waste sites. Under the 
Superfund Act, all parties who may have contributed any waste to a hazardous 
waste site, identified by such Agency, are jointly and severally liable for 
the cost of cleanup unless the Agency agrees otherwise. It is Corning's 
policy to accrue for its estimated liability based on expert analysis and 
continual monitoring by both internal and external consultants. Corning has 
accrued for its estimated liability with respect to each of these sites and 
has not reduced the liability for any potential insurance recoveries. The 
aggregate liability is not material to the Company's operations or financial 
position. 
Effects of Inflation 
Amounts reflected in the financial statements do not provide for the effect 
of inflation on operations or financial position. The expenses and asset 
values, specifically those related to long-lived assets, reflect historical 
cost and do not necessarily represent replacement cost or charges to 
operations based on replacement cost. Corning's operations are geared to 
provide funds from operations which would be sufficient along with other 
sources to replace fixed assets as necessary. Net income would be lower than 
reported if the effects of inflation were reflected by charging operations 
for replacement costs. 

                             BUSINESS OF CORNING 

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

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

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

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

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

   
In March 1994, Dow Corning, along with other defendants and representatives 
of breast implant litigation plaintiffs, signed 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. Such period has been 
extended to July 1, 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. 

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 to maintain its capital account
balance at 21% of all the capital contributed to Corning Delaware by the 
holders of the Preferred Securities. 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    % 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             shares of Corning Common Stock for 
each $50 principal amount of Subordinated Debentures (equivalent to a 
conversion rate of        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 con 
verted 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 PartnershipAgreement, a copy of 
which is filed as an exhibit to the Registration Statement of which this 
Prospectus is a part. 

General 

   
All of the partnership interests in Corning Delaware other than the Preferred 
Securities (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          , 1994 and 
payable monthly in arrears on the last day of each calendar month of each 
year, commencing            , 1994 ("dividends"). The dividends payable on 
each Preferred Security will be fixed at a rate per annum of $            or 
    % of the liquidation preference of $50. The amount of dividends payable 
for any period will be computed on the basis of twelve 30-day months and a 
360-day year and, for any period shorter than a full month, will be computed 
on the basis of the actual number of days elapsed in such period. 
    

   
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     % 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      , 
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                   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"):

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 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           shares of Corning 
Common Stock for each Preferred Security (equivalent to a conversion price of 
$        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          , 1998, an amount per Preferred Security 
of $       (for the twelve month period ended           , 1995), $       (for 
the twelve month period ended           , 1996), $       (for the twelve 
month period ended           , 1997) and $       (for the twelve month period 
ended           , 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 $       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 
             , 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 $       (which is an 
amount equal to 66-2/3% of the reported last sale price for the Corning 
Common Stock on the NYSE on            , 1994), and in the event of any 
adjustment to the conversion price other than as a result of a Non-Stock 
Fundamental Change, the Reference Market Price shall also be adjusted so that 
the ratio of the Reference Market Price to the conversion price after giving 
effect to any such adjustment shall always be the same as the ratio of $ 
to the initial conversion price of the Preferred Securities. 
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,           shares (          shares if the Underwriters' 
over-allotment option is exercised in full) of Corning Series C Preferred 
Stock for issuance upon exchange of the Preferred Securities (as described 
under " --Preferred Securities--Optional Exchange for Corning Series C 
Preferred Stock" above). At the time the Preferred Securities are issued, all 
corporate action required in connection with the issuance of the Corning 
Series C Preferred Stock upon the making of an Exchange Election will have 
been taken. The terms of the Corning Series C Preferred Stock 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            , 2024 
or the date upon which Corning Delaware is dissolved, wound-up, liquidated or 
terminated. 

Prepayment 

   
Corning will have the right to prepay the Subordinated Debentures, in whole 
or in part (together with any accrued but unpaid interest on the portion 
being prepaid), at any time on or after       , 1998, during the twelve-month 
periods beginning on             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>
<CAPTION>
                              Prepayment Price 
Year                       (% of principal amount) 
<S>                        <C>

1999 
2000 
2001 
2002 
2003 
2004 and thereafter 
</TABLE>

Interest 

   
The Subordinated Debentures will bear interest at the rate of     % per annum 
from the original date of issuance, payable monthly in arrears on the last 
day of each calendar month of each year (each an "Interest Payment Date"), 
commencing            , 1994. Interest will compound monthly and will accrue 
at the annual rate of    % on any interest installment not paid 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 June 27, 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     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 bind 
    

ing 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       , 2004 and Corning Delaware will 
pay a corresponding redemption premium to holders of Preferred Securities 
whose Preferred Securities are redeemed before          , 2004. Corning 
Delaware will 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 Preferred Securities on 
the Business Day preceding the last day of each calendar month. As a result 
of such monthly allocation, a holder purchasing Preferred Securities may be 
allocated tax items attributable to periods before the transfer. The use of 
such monthly allocation may not be permitted under applicable Treasury 
Regulations, and, if not allowed, taxable income of Corning Delaware may be 
reallocated among holders of Preferred Securities. The General Partner is 
authorized to adjust allocations if necessary to reflect the economic income 
of holders or as otherwise required by the Code. 

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

                                 UNDERWRITING 

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

<TABLE>
<CAPTION>
                                   Number of 
Underwriter                   Preferred Securities 
<S>                           <C>
Goldman, Sachs & Co. 
Lazard Freres & Co. 

  Total                                         ,000 
</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 $  .   per Preferred Security. The Underwriters 
may allow, and such dealers may reallow, a concession not in excess of $  . 
per Preferred Security to certain brokers and dealers. After the Preferred 
Securities are released for sale to the public, the offering price and other 
selling terms may from time to time be varied by the representatives. 
    

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

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

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

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

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

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

      (c) William C. Ughetta, Esq., Senior Vice President and

      Company is a party or of which any property of the
      Company is the subject and no such proceedings are
      threatened or contemplated by governmental authorities

      thereof contained in the Prospectus; and all of the
      issued partnership interests of the Company, other than

      and clear of all liens, encumbrances, equities or claims;

       (iv) The Guarantor Agreements have each been
      duly authorized, executed and delivered by the
      Guarantor and the Company and such Agreements
      constitute legal, valid and binding obligations of the
      Guarantor and the Company, as the case may be,
      enforceable in accordance with their respective terms,
      subject, as to enforcement, to bankruptcy, insolvency,
      fraudulent transfer, reorganization, moratorium and
      similar laws of general applicability relating to or

      principles; the Subordinated Debentures are entitled to
      the benefits provided by the Fiscal Agency Agreement;
      and the Guarantor Agreements conform in all material
      respects to the descriptions thereof in the Prospectus; 

        (v) The Shares have been duly and validly
      authorized by the Company, and, when issued and
      delivered against payment therefor as provided herein,
      will be duly and validly issued and fully paid and non-
      assessable and will conform to the description thereof
      contained in the Prospectus; the Shares have the rights

      the Shares are valid and binding on the Company; the
      Shares are convertible through the Company into
      shares of Corning Common Stock and exchangeable
      through the Company for shares of Corning Preferred

      Corning Common Stock initially issuable upon
      conversion of the Subordinated Debentures and the
      shares of Corning Preferred Stock initially issuable
      upon exchange of the Subordinated Debentures have
      been duly authorized and reserved for issuance and,
      when issued and delivered in accordance with the
      terms of the Subordinated Debentures, will be duly and
      validly issued, fully paid and non-assessable and will
      conform in all material respects to the descriptions
      thereof contained in the Prospectus; the terms of the
      Corning Preferred Stock are valid and binding on
      Corning; and the holders of outstanding capital stock of
      the Guarantor are not entitled to preemptive or other
      rights afforded by the Guarantor to subscribe for the
      shares of Corning Common Stock or the shares of
      Corning Preferred Stock issuable through the Company
      upon conversion or exchange of the Shares;

       (vi) With such exceptions as are not material, the
      Guarantor has been duly qualified as a foreign
      corporation for the transaction of business and is in
      good standing under the laws of each United States
      jurisdiction in which it owns or leases properties, or
      conducts any business, so as to require such
      qualification, or is subject to no material liability or
      disability by reason of failure to be so qualified in any
      such jurisdiction (such counsel being entitled to rely in
      respect of the opinion in this clause (vi) upon opinions
      of local counsel and in respect of matters of fact upon
      certificates of public officials or officers of the
      Guarantor, provided that such counsel shall state that
      he believes that both you and he are justified in so
      relying upon such opinions and certificates);

      (vii) To the best of such counsel's knowledge and
      other than as set forth in the Prospectus, there are no
      legal or governmental proceedings pending to which the
      Guarantor or any of the Guarantor's subsidiaries is a
      party or of which any property of the Guarantor or any
      of the Guarantor's subsidiaries is the subject (other
      than as set forth in the Prospectus and other than
      litigation incident to the kind of business conducted by
      the Guarantor and its subsidiaries, none of which
      litigation is material to the Guarantor and its
      subsidiaries considered as a whole) which, if
      determined adversely to the Guarantor or any of the
      Guarantor's subsidiaries, as the case may be, would
      individually or in the aggregate have a material adverse
      effect on the consolidated financial position,
      stockholders' equity or results of operations of the
      Guarantor and its subsidiaries; and, to the best of such
      counsel's knowledge, no such proceedings are
      threatened by governmental authorities or by others;
      and such counsel has not received notice that any such
      proceedings are threatened by governmental authorities
      or by others;

     (viii) This Agreement has been duly authorized,

      of this Agreement, the purchase by the Company of the
      Subordinated Debentures, the execution, delivery and

      Company is a party or by which the Company is bound
      or to which any of the property or assets of the
      Company is subject, nor will such action result in any
      violation of the provisions of the Partnership Agreement
      or certificate of limited partnership of the Company or

      such counsel of any court or governmental agency or

        (x) No consent, approval, authorization, order,

      purchase of the Shares and the distribution of the
      Shares by the Underwriters;

       (xi) The issue and sale of the Shares by the
      Company and the issuance by Corning of the shares of

      exchange of the Subordinated Debentures by the
      Guarantor, the compliance by the Guarantor with all of
      the provisions of this Agreement, the execution, delivery
      and performance by the Guarantor of the Guarantor
      Agreements and the consummation of the transactions
      herein and therein contemplated will not conflict with or
      result in a breach of any of the terms or provisions of,
      or constitute a default under, any indenture, mortgage,
      deed of trust, loan agreement or other agreement or
      instrument known to such counsel to which the
      Guarantor or any of the Guarantor's subsidiaries is a
      party or by which the Guarantor or any of the
      Guarantor's subsidiaries is bound or to which any of the
      property or assets of the Guarantor or any of the
      Guarantor's subsidiaries is subject, nor will such action
      result in any violation of the provisions of the Certificate
      of Incorporation or by-laws of the Guarantor or any
      statute or any order, rule or regulation known to such
      counsel of any court or governmental agency or body
      having jurisdiction over the Guarantor, any of the
      Guarantor's subsidiaries or any of their properties;

      (xii) No consent, approval, authorization, order,
      registration or qualification of or with any such court or
      governmental agency or body is required for the issue
      of the Guarantee, the issuance of the shares of Corning
      Common Stock issuable upon conversion of the
      Subordinated Debentures or the issuance of the
      Corning Preferred Stock issuable upon exchange of the
      Subordinated Debentures or the consummation by the
      Guarantor of the transactions contemplated herein and
      therein, except the registration under the Act of the
      Registered Securities, which has been made, and such
      consents, approvals, authorizations, registrations or
      qualifications as have been obtained or may be
      required under state securities or Blue Sky laws in
      connection with the purchase of the Shares and the
      distribution of the Shares by the Underwriters;


     (xiii) The statements set forth in the Prospectus
      under the captions "Description of Securities Offered",
      "Description of Corning Capital Stock" and
      "Underwriting", insofar as they constitute summaries of
      securities or documents are accurate summaries and
      fairly present the information with respect to such
      securities or documents and insofar as they constitute
      matters of law or legal conclusions are accurate, correct
      and fairly present the information set forth therein;

      (xiv) Neither the Company nor the Guarantor is an
      "investment company" or an entity "controlled" by an
      "investment company" required to be registered under
      the Investment Company Act;

       (xv) The documents incorporated by reference in
      the Prospectus or any further amendment or
      supplement thereto made by the Company or the
      Guarantor prior to such Time of Delivery (other than the
      financial statements and related schedules therein, as
      to which such counsel need express no opinion), when
      they became effective or were filed with the
      Commission, as the case may be, complied as to form
      in all material respects with the requirements of the Act
      or the Exchange Act, as applicable, and the rules and
      regulations of the Commission thereunder; and such
      counsel has no reason to believe that any of such
      documents, when such documents became effective or
      were so filed, as the case may be, contained, in the
      case of a registration statement which became effective
      under the Act, an untrue statement of a material fact or
      omitted to state a material fact required to be stated
      therein or necessary to make the statements therein not
      misleading, or, in the case of other documents which
      were filed under the Exchange Act with the
      Commission, an untrue statement of a material fact or
      omitted to state a material fact necessary in order to
      make the statements therein, in the light of the
      circumstances under which they were made when such
      documents were so filed, not misleading; and

      (xvi) The Registration Statement and the
      Prospectus and any further amendments and
      supplements thereto made by the Company or the
      Guarantor prior to such Time of Delivery (other than the
      financial statements and related schedules therein, as
      to which such counsel need express no opinion) comply
      as to form in all material respects with the requirements
      of the Act and the rules and regulations thereunder;
      although such counsel does not assume any
      responsibility for the accuracy, completeness or fairness
      of the statements contained in the Registration
      Statement or the Prospectus, except for those referred
      to in the opinion in Subsection (xv) of this Section 7(c),
      such counsel has no reason to believe that, as of its
      effective date, the Registration Statement or any further
      amendment thereto made by the Company or the
      Guarantor prior to such Time of Delivery (other than the
      financial statements and related schedules therein, as
      to which such counsel need express no opinion)
      contained an untrue statement of a material fact or
      omitted to state a material fact required to be stated
      therein or necessary to make the statements therein, in
      the light of the circumstances under which they were
      made, not misleading or that, as of its date, the
      Prospectus or any further amendment or supplement
      thereto made by the Company prior to such Time of
      Delivery (other than the financial statements and related
      schedules therein and other financial data therein, as to
      which such counsel need express no opinion) contained
      an untrue statement of a material fact or omitted to
      state a material fact necessary to make the statements
      therein, in the light of the circumstances under which
      they were made, not misleading or that, as of such
      Time of Delivery either the Registration Statement or
      the Prospectus or any further amendment or
      supplement thereto made by the Company or the
      Guarantor prior to such Time of Delivery (other than the
      financial statements and related schedules therein, as
      to which such counsel need express no opinion)
      contained an untrue statement of a material fact or
      omitted to state a material fact necessary to make the
      statements therein, in light of the circumstances in
      which they were made, not misleading; and such
      counsel does not know of any amendment to the
      Registration Statement required to be filed or of any
      contracts or other documents of a character required to
      be filed as an exhibit to the Registration Statement or
      required to be incorporated by reference into the
      Prospectus or required to be described in the
      Registration Statement or the Prospectus which are not
      filed or incorporated by reference or described as
      required.

      (d) Shearman & Sterling, special counsel for the
Company and the Guarantor, shall have furnished to you their
written opinion, dated such Time of Delivery, in form and
substance satisfactory to you, to the same effect as the
opinions set forth in paragraphs (ii), (iv), (v), (xv) and (xvi) of

      (i) concerning the legal proceedings under the captions
      "Business of Corning -- Recent Developments -- Breast
      Implant Litigation" and "-- Other Legal Proceedings" and
      (ii) concerning the legal proceedings involving the billing
      practices of the Guarantor's Metpath division of its
      wholly owned subsidiary, Corning Lab Services, Inc.,
      under the caption "Business -- Recent Developments --
      Department of Justice Investigation", is appropriately
      responsive to the requirements of the Act and the rules
      and regulations thereunder; and

        (ii)  The statements made in the Prospectus
      under the caption "Certain Federal Income Tax
      Considerations", to the extent they constitute matters of

      to the limitations set forth therein, by such counsel and
      are accurate, correct and fairly present the information
      set forth therein.

      (e) On the date of this Agreement and also at each

respect to the Corning Preferred Stock executed and filed, in
each case in a form reasonably satisfactory to you;

      (g) (i) None of the Company, the Guarantor or any of
the Guarantor's subsidiaries shall have sustained since the date
of the latest audited financial statements included or
incorporated by reference in the Prospectus any loss or
interference with its business from fire, explosion, flood or other
calamity, whether or not covered by insurance, or from any
labor dispute or court or governmental action, order or decree,
otherwise than as set forth or contemplated in the Prospectus,
and (ii) since the respective dates as of which information is
given in the Prospectus there shall not have been any change
in the capital stock or long-term debt of the Guarantor or any of
the Guarantor's subsidiaries or any change, or any development
involving a prospective change, in or affecting the general
affairs, management, financial position or partners' capital of the
Company or the general affairs, management, consolidated
financial position, stockholders' equity or results of operations
of the Guarantor or the Guarantor's subsidiaries, otherwise than
as set forth or contemplated in the Prospectus, the effect of
which, in any such case described in Clause (i) or (ii), is in your
judgment so material and adverse as to make it impracticable
or inadvisable to proceed with the public offering of the Shares
or the delivery of the Shares being delivered at such Time of
Delivery on the terms and in the manner contemplated in the
Prospectus;

      (h) On or after the date hereof (i) no downgrading shall
have occurred in the rating accorded the Shares or any of the
Guarantor's debt securities or preferred stock by any "nationally
recognized statistical rating organization," as that term is
defined by the Commission for purposes of Rule 436(g)(2)

State authorities; or (iv) the outbreak or escalation of hostilities
involving the United States or the declaration by the United
States of a national emergency or war if the effect of any such
event specified in this Clause (iv) in your judgment makes it
impracticable or inadvisable to proceed with the public offering
of the Securities or the delivery of the Shares being delivered
at such Time of Delivery on the terms and in the manner
contemplated by the Prospectus;

      (j) The Shares to be sold by the Company at such Time
of Delivery shall have been duly listed, subject to notice of
issuance, on the New York Stock Exchange; and

      (k) The Company and the Guarantor shall have
furnished or caused to be furnished to you at such Time of
Delivery certificates of officers of the Company and the
Guarantor satisfactory to you, as to the accuracy of the
representations and warranties of the Company and the
Guarantor herein at and as of such Time of Delivery, as to the
performance by the Company and the Guarantor of all of their
obligations hereunder to be performed at or prior to such Time
of Delivery, as to the matters set forth in subsections (a) and (g)
of this Section and as to such other matters as you may
reasonably request.

8.  (a) The Company and the Guarantor will jointly and severally
indemnify and hold harmless each Underwriter against any losses,
claims, damages or liabilities, joint or several, to which such Underwriter
may become subject, under the Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of
or are based upon an untrue statement or alleged untrue statement of
a material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto,
or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary
to make the statements therein not misleading, and will reimburse each
Underwriter for any legal or other expenses reasonably incurred by such
Underwriter in connection with investigating or defending any such
action or claim as such expenses are incurred; provided, however, that
neither the Company nor the Guarantor shall be liable in any such case
to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or
omission or alleged omission made in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any such amendment or
supplement in reliance upon and in conformity with written information
furnished to the Company or the Guarantor by any Underwriter through
you expressly for use therein and provided, further, that neither the
Company nor the Guarantor shall be liable to the Underwriter under the
indemnity agreement in this subsection (a) with respect to any
Preliminary Prospectus to the extent that any such loss, claim, damage
or liability of the Underwriter results from the fact that the Underwriter
sold Shares to a person as to whom it shall be established that there
was not sent or given, at or prior to the written confirmation of such
sale, a copy of the Prospectus (excluding documents incorporated by
reference) in any case where such delivery is required by the Act if the
Company or the Guarantor has previously furnished copies thereof to
the Underwriter and the loss, claim, damage or lability of the Underwriter
results from an untrue statement or omission of a material fact
contained in the Preliminary Prospectus which was corrected in the
Prospectus (excluding documents incorporated by reference).

(b) Each Underwriter will indemnify and hold harmless the
Company and the Guarantor against any losses, claims, damages or
liabilities to which the Company or the Guarantor may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon
an untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Prospectus, the Registration Statement, or
the Prospectus or any amendment or supplement thereto, or arise out
of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, in each case to the extent, but only
to the extent, that such untrue statement or alleged untrue statement or
omission or alleged omission was made in any Preliminary Prospectus,
the Registration Statement or the Prospectus or any such amendment
or supplement in reliance upon and in conformity with written information
furnished to the Company or the Guarantor by such Underwriter through
you expressly for use therein; and will reimburse the Company and the
Guarantor for any legal or other expenses reasonably incurred by the
Company or the Guarantor in connection with investigating or defending
any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under
subsection (a) or (b) above of notice of the commencement of any
action, such indemnified party shall, if a claim in respect thereof is to be
made against the indemnifying party under such subsection, notify the
indemnifying party in writing of the commencement thereof, but the
omission so to notify the indemnifying party shall not relieve it from any
liability which it may have to any indemnified party otherwise than under
such subsection.  In case any such action shall be brought against any
indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it shall wish, jointly with any
other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (who shall
not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party under
such subsection for any legal expenses of other counsel or any other
expenses, in each case subsequently incurred by such indemnified
party, in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the written
consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending
or threatened action or claim in respect of which indemnification or
contribution may be sought hereunder (whether or not the indemnified
party is an actual or potential party to such action or claim) unless such
settlement, compromise or judgment (i) includes an unconditional
release of the indemnified party from all liability arising out of such
action or claim and (ii) does not include a statement as to an admission
of fault, culpability or a failure to act by or on behalf of any indemnified
party.

(d) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages
or liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof) in such proportion as is
appropriate to reflect the relative benefits received by the Company and
the Guarantor on the one hand and the Underwriters on the other from
the offering of the Shares.  If, however, the allocation provided by the
immediately preceding sentence is not permitted by applicable law or if
the indemnified party failed to give the notice required under subsection
(c) above, then each indemnifying party shall contribute to such amount
paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and the Guarantor on the one hand and the
Underwriters on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities
(or actions in respect thereof), as well as any other relevant equitable
considerations.  The relative benefits received by the Company and the
Guarantor on the one hand and the Underwriters on the other shall be
deemed to be in the same proportion as (i) the total proceeds from the
offering (before deducting expenses) received by the Company less the
total underwriting compensation paid by the Guarantor bears to (ii) the
total underwriting compensation received by the Underwriters, in each
case as set forth in, or in footnotes to, the table on the cover page of
the Prospectus.  The relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of
a material fact or the omission or alleged omission to state a material
fact relates to information supplied by the Company and the Guarantor
on the one hand or the Underwriters on the other and the parties'
relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.  The Company, the
Guarantor and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this subsection (d) were determined
by pro rata allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to above in this
subsection (d).  The amount paid or payable by an indemnified party as
a result of the losses, claims, damages or liabilities (or actions in
respect thereof) referred to above in this subsection (d) shall be deemed
to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such
action or claim.  Notwithstanding the provisions of this subsection (d),
no Underwriter shall be required to contribute any amount in excess of
the amount by which the total price at which the Shares underwritten by
it and distributed to the public were offered to the public exceeds the
amount of any damages which such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall
be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  The Underwriters' obligations in this
subsection (d) to contribute are several in proportion to their respective
underwriting obligations and not joint.

(e) The obligations of the Company and the Guarantor under
this Section 8 shall be in addition to any liability which the Company and
the Guarantor may otherwise have and shall extend, upon the same
terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 shall be in addition to any liability
which the respective Underwriters may otherwise have and shall extend,
upon the same terms and conditions, to each officer and director of the
Company and the Guarantor and to each person, if any, who controls
the Company or the Guarantor within the meaning of the Act.

9.  (a) If any Underwriter shall default in its obligation to
purchase the Shares which it has agreed to purchase hereunder at a
Time of Delivery, you may in your discretion arrange for you or another
party or other parties to purchase such Shares on the terms contained
herein.  If within thirty-six hours after such default by any Underwriter
you do not arrange for the purchase of such Shares, then the Company
and the Guarantor shall be entitled to a further period of thirty-six hours
within which to procure another party or other parties satisfactory to you
to purchase such Shares on such terms.  In the event that, within the
respective prescribed periods, you notify the Company and the
Guarantor that you have so arranged for the purchase of such Shares,
or the Company or the Guarantor notifies you that it has so arranged for
the purchase of such Shares, you or the Company and the Guarantor
shall have the right to postpone such Time of Delivery for a period of
not more than seven days, in order to effect whatever changes may
thereby be made necessary in the Registration Statement or the
Prospectus, or in any other documents or arrangements, and the
Company and the Guarantor agree to file promptly any amendments to
the Registration Statement or the Prospectus which in your opinion may
thereby be made necessary.  The term "Underwriter" as used in this
Agreement shall include any person substituted under this Section with
like effect as if such person had originally been a party to this
Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase
of the Shares of a defaulting Underwriter or Underwriters by you and the
Company and the Guarantor as provided in subsection (a) above, the
aggregate number of such Shares which remains unpurchased does not
exceed one-eleventh of the aggregate number of all the Shares to be
purchased at such Time of Delivery, then the Company and the
Guarantor shall have the right to require each non-defaulting
Underwriter to purchase the number of shares which such Underwriter
agreed to purchase hereunder at such Time of Delivery and, in addition,
to require each non-defaulting Underwriter to purchase its pro rata share
(based on the number of Shares which such Underwriter agreed to
purchase hereunder) of the Shares of such defaulting Underwriter or
Underwriters for which such arrangements have not been made; but
nothing herein shall relieve a defaulting Underwriter from liability for its
default.

(c) If, after giving effect to any arrangements for the purchase
of the Shares of a defaulting Underwriter or Underwriters by you and the
Company and the Guarantor as provided in subsection (a) above, the
aggregate number of such Shares which remains unpurchased exceeds
one-eleventh of the aggregate number of all the Shares to be purchased
at such Time of Delivery, or if the Company and the Guarantor shall not
exercise the right described in subsection (b) above to require non-
defaulting Underwriters to purchase Shares of a defaulting Underwriter
or Underwriters, then this Agreement (or, with respect to the Second
Time of Delivery, the obligations of the Underwriters to purchase and of
the Company and Guarantor to sell the Optional Shares) shall
thereupon terminate, without liability on the part of any non-defaulting
Underwriter, the Company or the Guarantor, except for the expenses to
be borne by the Company, the Guarantor and the Underwriters as
provided in Section 6 hereof and the indemnity and contribution
agreements in Section 8 hereof; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

10.  The respective indemnities, agreements, representations,
warranties and other statements of the Company, the Guarantor and the
several Underwriters, as set forth in this Agreement or made by or on
behalf of them, respectively, pursuant to this Agreement, shall remain
in full force and effect, regardless of any investigation (or any statement
as to the results thereof) made by or on behalf of any Underwriter or
any controlling person of any Underwriter, or the Company, the
Guarantor or any officer or director or controlling person of the Company
or the Guarantor, and shall survive delivery of and payment for the
Shares.

11.  If this Agreement shall be terminated pursuant to Section 9
hereof, neither the Company nor the Guarantor shall be under any
liability to any Underwriter except as provided in Section 6 and
Section 8 hereof; but if, for any other reason Shares are not delivered
by or on behalf of the Company as herein provided, the Company and
the Guarantor will reimburse the Underwriter for all out-of-pocket
expenses, including fees and disbursements of counsel, reasonably
incurred by the Underwriter in making preparations for the purchase,
sale and delivery of the Shares, but the Company and the Guarantor
shall then be under no further liability to the Underwriter in respect of
the Shares not so delivered except as provided in Section 6 and Section
8 hereof.

In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely
upon any statement, request, notice or agreement on behalf of any
Underwriter made or given by you jointly or by Goldman, Sachs & Co.
on behalf of you as representatives.

12.  All statements, requests, notices and agreements
hereunder shall be in writing, and if to the Underwriters shall be
delivered or sent by mail, telex or facsimile transmission to you as the
representatives in care of Goldman, Sachs & Co., 85 Broad Street, New
York, New York 10004, Attention: Registration Department; and if to the
Company or the Guarantor by mail to it at the address of the Company
or the Guarantor set forth in the Registration Statement, Attention:
Secretary; provided, however that any notice to an Underwriter pursuant
to Section 8(c) hereof shall be delivered or sent by mail, telex or
facsimile transmission to such Underwriter at its address set forth in its
Underwriters' Questionnaire, or telex constituting such Questionnaire,
which address will be supplied to the Company by you upon request.
Any such statements, requests, notices or agreements shall take effect
upon receipt thereof.

13.  This Agreement shall be binding upon, and inure solely to
the benefit of, the Underwriters, the Company, the Guarantor and, to the
extent provided in Sections 8 and 10 hereof, the officers and directors
of the Guarantor or the Company and each person who controls the
Company and the Guarantor or any Underwriter, and their respective
heirs, executors, administrators, successors and assigns, and no other
person shall acquire or have any right under or by virtue of this
Agreement.  No purchaser of any of the Shares from any Underwriter
shall be deemed a successor or assign by reason merely of such
purchase.

14.  Time shall be of the essence of this Agreement.  As used
herein, the term "business day" shall mean any day when the
Commission's office in Washington, D.C. is open for business.

15.  This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

16.  This Agreement may be executed by any one or more of
the parties hereto in any number of counterparts, each of which shall be
deemed to be an original, but all such counterparts shall together
constitute one and the same instrument.
<PAGE>
If the foregoing is in accordance with your understanding,
please sign and return to us two counterparts hereof, and upon the
acceptance hereof by you, on behalf of each of the Underwriters, this
letter and such acceptance hereof shall constitute a binding agreement
between each of the Underwriters, on the one hand, and the Company
and the Guarantor, on the other hand.  It is understood that your
acceptance of this letter on behalf of each of the Underwriters is
pursuant to the authority set forth in a form of Agreement among
Underwriters, the form of which shall be submitted to the Company and
the Guarantor for examination upon request, but without warranty on
your part as to the authority of the signers thereof.

         [Form of letter of Price Waterhouse
      to be delivered pursuant to Section 7(e)]


  Pursuant to Section 7(f) of the Underwriting Agreement, the
accountants shall furnish letters to the Underwriters to the effect that:

       (i) They are independent certified public accountants with
  respect to the Guarantor and its subsidiaries within the meaning
  of the Act and the applicable published rules and regulations
  thereunder;

      (ii) In their opinion, the financial statements and any
  supplementary financial information and schedules (and, if
  applicable, financial forecasts and/or pro forma financial
  information)  examined by them and included or incorporated by
  reference in the Registration Statement or the Prospectus
  comply as to form in all material respects with the applicable
  accounting requirements of the Act or the Exchange Act, as
  applicable, and the related published rules and regulations
  thereunder; and, if applicable, they have made a review in
  accordance with standards established by the American Institute
  of Certified Public Accountants of the unaudited consolidated
  interim financial statements, selected financial data, pro forma
  financial information, financial forecasts and/or condensed
  financial statements derived from audited financial statements
  of the Guarantor for the periods specified in such letter, as
  indicated in their reports thereon, copies of which have been
  furnished to the representatives of the Underwriters (the
  "Representatives");

     (iii) They have made a review in accordance with
  standards established by the American Institute of Certified
  Public Accountants of the unaudited condensed consolidated
  statements of income, consolidated balance sheets and
  consolidated statements of cash flows included in the
  Prospectus as indicated in their reports thereon copies of which
  have been separately furnished to the Representative and on
  the basis of specified procedures including inquiries of officials
  of the Guarantor who have responsibility for financial and
  accounting matters regarding whether the unaudited condensed
  consolidated financial statements referred to in
  paragraph (vi)(A)(i) below comply as to form in all material
  respects with the applicable accounting requirements of the Act
  and the related published rules and regulations, nothing came
  to their attention that caused them to believe that the unaudited
  condensed consolidated financial statements do not comply as
  to form in all material respects with the applicable accounting
  requirements of the Act and the related published rules and
  regulations;

      (iv) The unaudited selected financial information with
  respect to the consolidated results of operations and financial
  position of the Guarantor for the five most recent fiscal years
  included in the Prospectus and included or incorporated by
  reference in Item 6 of the Guarantor's Annual Report on
  Form 10-K for the most recent fiscal year agrees with the
  corresponding amounts (after restatement where applicable) in
  the audited consolidated financial statements for such five fiscal
  years which were included or incorporated by reference in the
  Guarantor's Annual Reports on Form 10-K for such fiscal years;

       (v) They have compared the information in the
  Prospectus under selected captions with the disclosure
  requirements of Regulation S-K and on the basis of limited
  procedures specified in such letter nothing came to their
  attention as a result of the foregoing procedures that caused
  them to believe that this information does not conform in all
  material respects with the disclosure requirements of Items 301,
  302 and 503(d) respectively, of Regulation S-K;

      (vi) On the basis of limited procedures, not constituting an
  examination in accordance with generally accepted auditing
  standards, consisting of a reading of the unaudited financial
  statements and other information referred to below, a reading
  of the latest available interim financial statements of the
  Guarantor and its subsidiaries, inspection of the minute books
  of the Guarantor and its subsidiaries since the date of the latest
  audited financial statements included or incorporated by
  reference in the Prospectus, inquiries of officials of the
  Guarantor and its subsidiaries responsible for financial and
  accounting matters and such other inquiries and procedures as
  may be specified in such letter, nothing came to their attention
  that caused them to believe that:

                (A) (i) the unaudited condensed consolidated
         statements of income, consolidated balance sheets and
         consolidated statements of cash flows included in the
         Prospectus and/or incorporated by reference in the
         Guarantor's Quarterly Reports on Form 10-Q
         incorporated by reference in the Prospectus do not
         comply as to form in all material respects with the
         applicable accounting requirements of the Exchange
         Act as it applies to Form 10-Q and the related
         published rules and regulations thereunder or (ii) any
         material modifications should be made to the unaudited
         consolidated statements of income, consolidated
         balance sheet and consolidated statements of cash
         flows included in the Prospectus or included in the
         Guarantor's Quarterly Reports on Form 10-Q
         incorporated by reference in the Prospectus, for them
         to be in conformity with generally accepted accounting
         principles;

                (B) any other unaudited income statement data
         and balance sheet items included in the Prospectus do
         not agree with the corresponding items in the unaudited
         consolidated financial statements from which such data
         and items were derived, and any such unaudited data
         and items were not determined on a basis substantially
         consistent with the basis for the corresponding amounts
         in the audited consolidated financial statements
         included or incorporated by reference in the
         Guarantor's Annual Report on Form 10-K for the most
         recent fiscal year;

                (C) the unaudited financial statements which
         were not included in the Prospectus but from which
         were derived the unaudited condensed financial
         statements referred to in Clause (A) and any unaudited
         income statement data and balance sheet items
         included in the Prospectus and referred to in Clause (B)
         were not determined on a basis substantially consistent
         with the basis for the audited financial statements
         included or incorporated by reference in the
         Guarantor's Annual Report on Form 10-K for the most
         recent fiscal year;

                (D) any unaudited pro forma consolidated
         condensed financial statements included or
         incorporated by reference in the Prospectus do not
         comply as to form in all material respects with the
         applicable accounting requirements of the Act and the
         published rules and regulations thereunder or the pro
         forma adjustments have not been properly applied to
         the historical amounts in the compilation of those
         statements;

                (E) as of a specified date not more than five
         days prior to the date of such letter, there have been
         any changes in the consolidated capital stock (other
         than issuances of capital stock upon exercise of options
         and stock appreciation rights, upon earn-outs of
         performance shares and upon conversions of
         convertible securities, in each case which were
         outstanding on the date of the latest balance sheet
         included or incorporated by reference in the
         Prospectus), or any increase in the consolidated long-
         term debt of the Guarantor and its subsidiaries or any
         increases in any items specified by the
         Representatives, in each case as compared with
         amounts shown in the latest balance sheet included or
         incorporated by reference in the Prospectus, except in
         each case for changes, increases or decreases which
         the Prospectus discloses have occurred or may occur
         or which are described in such letter; and

                (F) for the period from the date of the latest
         financial statements included or incorporated by
         reference in the Prospectus to the specified date
         referred to in Clause (E) there were any decreases in
         consolidated net revenue or other items specified by
         the Representatives, or any increases in any items
         specified by the Representatives, in each case as
         compared with the comparable period in the preceding
         year and with any other period of corresponding length
         specified by the Representatives, except in each case
         for increases or decreases which the Prospectus
         discloses have occurred or may occur or which are
         described in such letter; and

     (vii) In addition to the audit referred to in their report(s)
  included or incorporated by reference in the Prospectus and the
  limited procedures, inspection of minute books, inquiries and
  other procedures referred to in paragraphs (iii), (iv), (v) and (vi)
  above, they have carried out certain specified procedures, not
  constituting an examination in accordance with generally
  accepted auditing standards, with respect to certain amounts,
  percentages and financial information specified by the
  Representatives which are derived from the general accounting
  records of the Guarantor and its subsidiaries, which appear in
  the Prospectus (excluding documents incorporated by
  reference) or in Part II of, or in exhibits and schedules to, the
  Registration Statement specified by the Representatives or in
  documents incorporated by reference in the Prospectus
  specified by the Representatives, and have compared certain of
  such amounts, percentages and financial information with the
  accounting records of the Guarantor and its subsidiaries and
  have found them to be in agreement.

  All references in this Annex I to the Prospectus shall be deemed
to refer to the Prospectus (including the documents incorporated by
reference therein) as defined in the Underwriting Agreement as of the
date of the letter delivered on the date of the Underwriting Agreement
and to the Prospectus as amended or supplemented (including all
documents incorporated by reference therein) for the purposes of the
letter delivered at each Time of Delivery.<PAGE>

      [Form of Letter of Arthur Andersen & Co.
      to be delivered pursuant to Section 7(e)]

       (i) They are independent certified public accountants with
  respect to Damon Corporation ("Damon") and its subsidiaries
  within the meaning of the Act and the applicable published rules
  and regulations thereunder;

      (ii) In their opinion, the financial statements and any
  supplementary financial information and schedules audited (and,
  if applicable, financial forecasts and/or pro forma financial
  information) examined by them and included or incorporated by
  reference in the Prospectus or the Registration Statement
  comply as to form in all material respects with the applicable
  accounting requirements of the Act or the Exchange Act, as
  applicable, and the related published rules and regulations
  thereunder; and, if applicable, they have made a review in
  accordance with standards established by the American Institute
  of Certified Public Accountants of the unaudited consolidated
  interim financial statements, selected financial data, pro forma
  financial information, financial forecasts and/or condensed
  financial statements derived from audited financial statements
  of Damon for the periods specified in such letter, as indicated
  in their reports thereon, copies of which have been furnished to
  the Underwriter;

                (iii) The unaudited selected financial information with
          respect to the consolidated results of operations and financial
          position of Damon for the three most recent fiscal years
          included or incorporated by reference in the Prospectus agrees
          with the corresponding amounts (after restatement where
          applicable) in the audited consolidated financial statements for
          such three fiscal years which were included or incorporated by
          reference in Damon's Annual Reports on Form 10-K for such
          fiscal years;

                 (iv) On the basis of limited procedures, not constituting an
          audit in accordance with generally accepted auditing standards,
          consisting of a reading of the unaudited financial statements
          and other information referred to below, a reading of the latest
          available interim financial statements of Damon and its
          subsidiaries, inspection of the minute books of Damon and its
          subsidiaries since the date of the latest audited financial
          statements included or incorporated by reference in the
          Prospectus, inquiries of officials of Damon and its subsidiaries
          responsible for financial and accounting matters and such other
          inquiries and procedures as may be specified in such letter,
          nothing came to their attention that caused them to believe that:

                        (A)(i) the unaudited consolidated statements of
                   income, consolidated balance sheets and consolidated
                   statements of cash flows of Damon included or
                   incorporated by reference in the Prospectus do not
                   comply as to form in all material respects with the
                   applicable accounting requirements of the Exchange Act
                   as it applies to Form 10-Q and the related published
                   rules and regulations thereunder, or (ii) any material
                   modifications should be made to the unaudited
                   condensed consolidated statements of income,
                   consolidated balance sheets and consolidated
                   statements of cash flows included or incorporated by
                   reference in the Prospectus, for them to be in conformity
                   with generally accepted accounting principles;

                        (B) any other unaudited income statement data and
                   balance sheet items of Damon included in the
                   Prospectus do not agree with the corresponding items
                   in the unaudited consolidated financial statements from
                   which such data and items were derived, and any such
                   unaudited data and items were not determined on a
                   basis substantially consistent with the basis for the
                   corresponding amounts in the audited consolidated
                   financial statements of Damon included or incorporated
                   by reference in the Prospectus; and

                        (C) the unaudited financial statements of Damon
                   which were not included in the Prospectus but from
                   which were derived any unaudited condensed financial
                   statements referred to in Clause (A) and any unaudited
                   income statement data and balance sheet items
                   included in the Prospectus and referred to in Clause (B)
                   were not determined on a basis substantially consistent
                   with the basis for the audited consolidated financial
                   statements of Damon included or incorporated by
                   reference in the Prospectus.

          All references in this Annex II to the Prospectus shall be
deemed to refer to the Prospectus (including the documents
incorporated by reference therein) as defined in the Underwriting
Agreement as of the date of the letter delivered on the date of the
Underwriting Agreement and to the Prospectus as amended or
supplemented (including all documents incorporated by reference
therein) for the purposes of the letter delivered at each Time of Delivery.

                                   Losses allocated to each such
                                   Holder from the date of issuance of
                                   the Preferred Security through and
                                   including the close of such Fiscal
                                   Period pursuant to Section 4.1(b)(ii)
                                   over (y) the amount of Net Income
                                   allocated to each such Holder
                                   pursuant to this Section 4.1(a)(ii) in
                                   all prior Fiscal Periods. 

                     (iii)  Any remaining Net Income shall be
              allocated to the General Partner.

              (b)    The Partnership's Net Loss for any Fiscal Period
shall be allocated as follows:

                     (i)    First, to the General Partner until the
              balance of the General Partner's Capital Account is
              reduced to zero.

                     (ii)   Second, among the Holders in proportion
              to their respective aggregate Capital Account balances,
              until the Capital Account balances of such Holders are
              reduced to zero; provided, however, that the General
              Partner shall make appropriate adjustments in these
              allocations, in accordance with Section 4.1(c), with
              respect to any Preferred Securities as to which Net
              Income has been allocated with respect to Dividends that
              accrued but were not paid.

                     (iii)  Any remaining Net Loss shall be allocated
              to the General Partner.

              (c)    The General Partner shall make such changes to
the allocations in Sections 4.1(a) and 4.1(b) as it deems reasonably
necessary so that, in the year of the Partnership's liquidation, amounts
distributed to the Preferred Security Holders in accordance with Section
11.4(ii) shall equal their Liquidation Distributions.

              Section 4.2   Special Allocations.

              (a)    If a Holder delivers an irrevocable notice of
conversion ("Notice of Conversion") to the Partnership pursuant to
Section 6.3(b) of this Agreement, income, gain or loss, if any, realized
or recognized by the Partnership upon a conversion of Subordinated
Debentures into Corning Common Stock pursuant to such Notice of
Conversion shall be allocated to the Holder on whose behalf the
Partnership converted such Subordinated Debentures.

              (b)    If a Holder delivers a Notice of Conversion to the
Partnership which instructs the Partnership to convert Subordinated
Debentures into Corning Common Stock, such Holder shall be allocated
any interest (including original issue discount) accruing on a daily basis
on the Subordinated Debentures so converted until the date of such
conversion, but only to the extent such interest was not previously
allocated to the Partners in a prior Fiscal Period as part of Net Income
under Section 4.1(a) of this Agreement. 

              (c)    After the Tax Event Date, the Net Income
allocated to Holders shall be reduced to the extent any Dividends
payable to Holders are reduced pursuant to Section 6.2(b)(v) of this
Agreement.
<PAGE>
              (d)    If the Partnership receives a prepayment premium
upon a prepayment of some or all of the Subordinated Debentures,
income, gain or loss realized or recognized by the Partnership from such
prepayment shall be allocated to the Holders whose Preferred Securities
are redeemed pursuant to Section 6.2(e) of this Agreement as a result of
such prepayment.


              (e)    All expenditures described in Code Section
705(a)(2)(B) that are incurred by, or on behalf of, the Partnership and
paid by the General Partner shall be allocated entirely to the General
Partner.

              (f)    In the event any Holder unexpectedly receives any
adjustments, allocations or distributions described in Treasury
Regulation Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Partnership 
Net Income shall be specially allocated to such Holder in an amount and
manner sufficient to eliminate, to the extent required by the Treasury
Regulations, the deficit, if any, in the balance of the Capital Account of
such Holder as quickly as possible.  This Section 4.2(e) is intended to
comply with the qualified income offset provision in Section 1.704-
1(b)(2)(ii)(d) of the Treasury Regulations.

              (g)    For purposes of determining the profits, losses or
any other items allocable to any period, profits, losses and any such
other items shall be determined on a daily, monthly or other basis, as
determined by the General Partner using any method that is permissible
under Section 706 of the Code and the Treasury Regulations promulgated
thereunder.  Unless otherwise required, such profits, losses or other
items shall be determined for each Fiscal Period.

              (h)    The Partners are aware of the income tax
consequences of the allocations made by this Article IV and hereby
agree to be bound by the provisions of this Article IV in reporting their
shares of Partnership Net Income and Net Loss for U.S. federal income
tax purposes.

              (i)    Notwithstanding anything to the contrary that may
be expressed or implied in this Article IV, the interest of the General
Partner in each item of income, gain, loss, deduction and credit will be
equal to at least (i) at any time that aggregate capital contributions to
the Partnership are equal to or less than $50,000,000, 1% of each such
item and (ii) at any time that aggregate capital contributions to the
Partnership are greater than $50,000,000, at least 1%, multiplied by a
fraction (not exceeding one and not less than 0.2), the numerator of
which is $50,000,000 and the denominator of which is the lesser of the
aggregate Capital Account balances of the Capital Accounts of all
Partners at such time and the aggregate capital contributions to the
Partnership of all Partners at such time.

              (j)    The Partners intend that the allocations under
Section 4.1 conform to Treasury Regulation Section 1.704-1(b) and 1.704-2
(including, without limitation, the minimum gain chargeback,
chargeback of partner nonrecourse debt minimum gain, qualified income
offset and partner nonrecourse debt provisions of such Treasury
Regulations), and the General Partner shall make such changes in the
allocations under Section 4.1 as it believes are reasonably necessary to
meet the requirements of such Treasury Regulations.

              (k)    Solely for the purpose of adjusting the Capital
Accounts of the Partners, and not for tax purposes, if any property is
distributed in kind to any Partner, the difference between its fair market
value and its book value at the time of distribution shall be treated as
gain or loss recognized by the Partnership and allocated pursuant to the
provisions of Section 4.1.

              Section 4.3   Allocations for Income Tax Purposes.  The
income, gains, losses, deductions and credits of the Partnership shall be
allocated in the same manner as the items entering into the computation
of Net Income and Net Loss are allocated under Sections 4.1 and 4.2;
provided however, that solely for federal, state and local income and
franchise tax purposes, but not for book or Capital Account purposes,
income, gain, loss and deductions with respect to any property properly
carried on the Partnership's books at a value other than the tax basis of
such property shall be allocated in a manner determined in the General
Partner's discretion, so as to take into account (consistently with Code
Section 704(c) principles) the difference between such property's book
value and its tax basis.  Notwithstanding anything to the contrary set
forth in this Agreement, the General Partner is authorized to modify the
allocations of this Section 4.3, and Sections 4.1 and 4.2, if necessary or
appropriate, in the General Partner's sole discretion, for the allocations
to fairly reflect the economic gain, income or loss to each of the
Partners, or as otherwise required by the Code or the Treasury
Regulations.
<PAGE>
              Section 4.4   Withholding.  The Partnership shall
comply with withholding requirements under federal, state and local law
and shall remit amounts withheld to and file required forms with
applicable jurisdictions.  To the extent that the Partnership is required to
withhold and pay over any amounts to any authority with respect to
distributions or allocations to any Partner, the amount withheld shall be
deemed to be a distribution in the amount of the withholding to the
Partner.  In the event of any claimed over-withholding, Partners shall be
limited to an action against the applicable jurisdiction.  If the amount
withheld was not withheld from actual distributions, the Partnership may
reduce subsequent distributions by the amount of such withholding. 
Each Partner agrees to furnish the Partnership with any representations
and forms as shall reasonably be requested by the Partnership to assist it
in determining the extent of, and in fulfilling, its withholding
obligations.


                               ARTICLE V

                      DIVIDENDS AND DISTRIBUTIONS

              Section 5.1   Dividends.  Limited Partners shall receive
periodic Dividends, if any, redemption payments and liquidation
distributions in accordance with the terms of the Preferred Securities set
forth in Article VI.  Subject to the rights of the Preferred Security
Holders, all cash remaining in the Partnership Distribution Account shall
be distributed to the General Partner at such time as the General Partner
shall determine.

              Section 5.2   Limitations on Distributions.  The
Partnership shall not make a distribution to any Partner on account of
such Partner's Interest if such distribution would violate Section 17-607
of the Act or other applicable law.

                              ARTICLE VI

                   ISSUANCE OF PREFERRED SECURITIES

              Section 6.1   General Provisions Regarding Preferred
Securities.

              (a)    There is hereby authorized for issuance and sale
Preferred Securities having an aggregate liquidation preference not
greater than $____ and having the designation, annual Dividend rate,
liquidation preference, redemption terms, conversion and exchange
rights and other powers, preferences and special rights and limitations
set forth in this Article VI.  The aggregate liquidation preference of
Preferred Securities authorized hereunder shall be reduced 30 days after
the first Closing Date to the amount purchased by the Underwriters.

              (b)    The payment of Dividends and payments of
distributions by the Partnership in liquidation or on redemption in
respect of Preferred Securities shall be guaranteed by Corning pursuant
to the Guarantee.  In the event of an appointment of a Special General
Partner pursuant to Section 6.2(g), among other things, to enforce the
Guarantee, the Special General Partner may take possession of the
Guarantee for such purpose.  The Preferred Security Holders, by
acceptance of such Preferred Securities, acknowledge and agree to the
subordination provisions in, and other terms of, the Guarantee.

              (c)    The proceeds received by the Partnership from the
issuance of    Preferred Securities, together with the proceeds of the
capital contributed by the General Partner pursuant to Section 3.1(a) of
this Agreement, but less any amounts deposited by the General Partner
in the Eligible Investment Account pursuant to Section 3.6(a), shall be
invested by the Partnership in Subordinated Debentures with (i) an
aggregate principal amount equal to such aggregate proceeds and (ii) an
interest rate at least equal to the Dividend rate of the Preferred
Securities.

              (d)    The Partnership may not issue any other interests
in the Partnership, without the approval of the Holders of not less than
66 2/3% in Liquidation Preference of the Preferred Securities; provided,
however, that the Partnership may issue a general partnership interest to
the Special General Partner.  All Preferred Securities shall rank senior
to all other Interests in the Partnership in respect of the right to receive
Dividends or other distributions and the right to receive payments out of
the assets of the Partnership upon voluntary or involuntary liquidation,
dissolution, winding-up or termination of the Partnership.  All Preferred
Securities redeemed, purchased or otherwise acquired by the Partnership
(including Preferred Securities surrendered for conversion or exchange)
shall be canceled.  The Preferred Securities will be issued in registered
form only.  Dividends on all Preferred Securities shall be cumulative.

              (e)    No Holder shall be entitled as a matter of right to
subscribe for or purchase, or have any preemptive right with respect to,
any part of any new or additional  limited partnership interests, or of
securities convertible into any Preferred Securities or other limited
partnership interests, whether now or hereafter authorized and whether
issued for cash or other consideration or by way of a Dividend.

              (f)    Neither Corning nor any Affiliate of Corning shall
have the right to vote or give or withhold consent with respect to any
Preferred Security owned by it, directly or indirectly, and, for purposes
of any matter upon which the Limited Partners may vote or give or
withhold consent as provided in this Agreement, Preferred Securities
owned by Corning or any Affiliate shall be treated as if they were not
outstanding.

              Section 6.2   Preferred Securities. 

              (a)    Designation.   The Preferred Securities, liquidation
preference $50 per Preferred Security, are hereby designated as "    %
Convertible Monthly Income Preferred Securities."

              (b)    Dividends.  (i)  Preferred Security Holders shall
be entitled to receive, when, as and if declared by the General Partner,
cumulative Dividends at a rate per annum of       % of the stated
liquidation preference of $50 per Preferred Security, calculated on the
basis of a 360-day year consisting of 12 months of 30 days each.  For
any period shorter than a full monthly Dividend period, Dividends will 
be computed on the basis of the actual number of days elapsed in 
such period. Dividends shall be payable in United States dollars 
monthly in arrears on the last day of each calendar month of 
each year, commencing         1994.  Such Dividends will accrue 
and be cumulative whether or not they have been declared and 
whether or not there are funds of the Partnership legally available 
for the payment of Dividends. Dividends on the Preferred Securities 
shall be cumulative from the first Closing Date.  Additional 
Dividends upon any Dividend arrearages shall be declared
and paid in order to provide, in effect, monthly compounding on such
Dividend arrearages at a rate of     % per annum compounded monthly
and such Additional Dividends shall accumulate.  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 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.  

              (ii)   Dividends on the Preferred Securities must be
declared monthly and paid on the last day of each calendar month (each
a "Dividend Payment Date") to the extent that the Partnership has, on
such date, (x) funds legally available for the payment of such Dividends
and (y) cash on hand sufficient to permit such payments, it being
understood that to the extent that funds are not available to pay in full
all accumulated and unpaid Dividends, the Partnership may pay partial
Dividends to the extent of funds legally available therefor.   For
purposes of this Section 6.2(b), net interest and investment income from
funds on deposit in the Eligible Investment Account that is transferred
into the Partnership Distribution Account shall be considered funds
available for the payment of Dividends; provided, however, that the
principal amount of Eligible Investments shall not be available as
distributions as Dividends or otherwise except in connection with a
liquidating distribution pursuant to Section 11.4 of this Agreement. 
Dividends will be payable to the Holders as they appear on the books
and records of the Partnership on the relevant record dates, which will
be one Business Day prior to the related Dividend Payment Date. In the
event of any extended interest payment period with respect to the
Subordinated Debentures resulting in the deferral of the payment of
Dividends on the Preferred Securities, the General Partner shall notify
the Holders as to such extended interest payment period. 
 
              (iii)  The Partnership shall not:

              (A)    pay, declare or set aside for payment, any
       dividends or other distributions on any other Interests in the
       Partnership; or

              (B)    redeem, purchase or otherwise acquire any other
       Interests in the Partnership;

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.

              (iv)   In the event of an election by the Holder to
convert its Preferred Securities into Corning Common Stock pursuant to
Section 6.3 of this Agreement, neither Corning nor the Partnership shall
make, or be required to make, any payment, allowance or adjustment
with respect to accumulated and unpaid Dividends on such Preferred
Securities; provided that Holders of Preferred Securities at the close of
business on any record date for the payment of Dividends will be
entitled to receive the Dividend payable on such Preferred Securities on
the corresponding Dividend Payment Date notwithstanding the
conversion of such Preferred Securities into Corning Common Stock
following such record date.

              (v)      In the case of a Tax Event, Dividends (including
any Additional Dividends) accruing and payable after the date (the "Tax
Event Date") that is the earlier of (A) the date three months after the
Notice Date and (B) the Meeting Date, shall be reduced by the portion
of Additional Taxes, if any, after such date that are allocable to Holders
of the Preferred Securities.   For purposes of this Agreement, Additional
Taxes shall be allocated between the General Partner and the Limited
Partners (and among the Limited Partners) in accordance with the
Partners' respective Interests in the Partnership.  Distributions to the
General Partner by the Partnership after such date shall be reduced by
the amount of Additional Taxes allocable to the General Partner. 
Pursuant to Section 9.3(b) of this Agreement, the General Partner shall
pay all Additional Taxes imposed on or payable by the Partnership
through the Tax Event Date.

              (d)    Redemption.  (i)  The Preferred Securities are
redeemable, at the option of the Partnership, in whole or in part from
time to time, on or after         1998, upon not fewer than 35 nor more
than 60 days' prior notice, during the twelve-month periods beginning
on _____ in each of the years below, at the following redemption prices
(expressed as a percentage of the liquidation preference), plus
accumulated and unpaid dividends, whether or not earned or declared
(the "Redemption Price"):

Date                        Redemption Price

1998                                  %
1999
2000
2001
2002
2003
2004 and thereafter                100

              (ii)   Upon repayment or prepayment of the
Subordinated Debentures, including as a result of the acceleration of the
Subordinated Debentures upon the occurrence of an Event of Default
with respect to the Subordinated Debentures, the proceeds from such
repayment or prepayment shall be applied to redeem the Preferred
Securities at the redemption price of $50 per Preferred Security plus
accumulated and unpaid Dividends (whether or not earned or declared)
plus Additional Dividends, if any, accrued thereon to the date fixed for
redemption, plus, in the case of a redemption as a result of any
prepayment of the Subordinated Debentures, any applicable premium.

              (iii)  In the event there is a prepayment or repayment of
Subordinated Debentures, with a corresponding redemption of Preferred
Securities, after the Tax Event Date, then the Redemption Price for any
Preferred Security shall be reduced by the amount of any Additional
Taxes attributable to the redemption of the Subordinated Debentures and
allocable to the Holders of the Preferred Securities that are redeemed as
a result of the prepayment or repayment of the Subordinated
Debentures.
       
              (e)    Redemption Procedures.  (i)  Notice of any
redemption (a "Notice of Redemption") of the Preferred Securities to be
redeemed will be given by the Partnership by mail to each record
Holder of Preferred Securities to be redeemed not fewer than 35 nor
more than 60 days prior to the date fixed for redemption thereof
following the issuance of a notice of prepayment or redemption of the
Subordinated Debentures by Corning to the Partnership.  For purposes
of the calculation of the date of redemption and the dates on which
notices are given pursuant to this paragraph (e)(i), a Notice of
Redemption shall be deemed to be given on the day such notice is first
mailed by first-class mail, postage prepaid, to each Holder of Preferred
Securities to be redeemed.  Each Notice of Redemption shall be
addressed to each Holder of Preferred Securities to be redeemed at the
address of the Holder appearing in the books and records of the
Partnership.  No defect in the Notice of Redemption or in the mailing
thereof with respect to any Preferred Security shall affect the validity of
the redemption proceedings with respect to any other Preferred Security.

              (ii)   In the event that fewer than all the outstanding
Preferred Securities are to be redeemed, the Preferred Securities to be
redeemed will be selected in accordance with paragraph (e)(iv) hereof. 
The Partnership may not redeem fewer than all the outstanding
Preferred Securities unless all accumulated and unpaid Dividends,
including any Additional Dividends, have been paid in full on all
Preferred Securities for all monthly Dividend periods terminating on or
prior to the date of redemption.

              (iii)  If, following a notice of prepayment of the
Subordinated Debentures, the Partnership issues a Notice of
Redemption, then, by 12:00 noon, New York time, on the redemption
date, Corning will repay to the Partnership an aggregate principal
amount of the Subordinated Debentures, which, together with accrued
and unpaid interest and any Additional Interest thereon, will be an
amount sufficient to pay the applicable Redemption Price, less any
amounts retained by the Partnership for the payment of Additional
Taxes pursuant to Section 6.2(d)(iii) of this Agreement.  If all of the
Preferred Securities are represented by Book-Entry Interests, the
Partnership shall irrevocably deposit such funds with the Clearing
Agency and give the Clearing Agency irrevocable instructions and
authority to pay the applicable Redemption Price to the Holders of
Preferred Securities to be redeemed and otherwise the Partnership may
pay the Redemption Price by check.  If Notice of Redemption shall
have been issued and funds deposited as required or a check deposited
in the U.S. mails postage prepaid, then upon the date of such deposit,
all rights of the Preferred Security Holders who hold such Preferred
Securities so called for redemption will cease, except the right of the
Holders of such securities to receive the Redemption Price, but without
interest from and after such redemption date.  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 which 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 in respect of Preferred Securities is
improperly withheld or refused and not paid either by the Partnership or
by Corning pursuant to the Guarantee, Dividends on such Preferred
Securities (including any Additional Dividends thereon) will continue to
accumulate at the then applicable rate, from the original redemption date
to the date that the Redemption Price is actually paid.

              (iv)   If all of the Preferred Securities are represented by
Book-Entry Interests, Notices of Redemption shall be sent to the
Clearing Agency.  If less than all of the Preferred Securities are being
redeemed, Interests to be redeemed shall, if all of the Preferred
Securities are represented by Book-Entry Interests, be determined in
accordance with the Clearing Agency's practice, which at the date
hereof is to determine by lot the amount of Preferred Securities of each
Preferred Security Owner that are to be redeemed, and otherwise by
such method as the General Partner determines to be fair and
reasonable.

              (f)    Liquidation Rights.  In the event of any voluntary
or involuntary liquidation, dissolution, winding-up or termination of the
Partnership, the Holders of Preferred Securities at the time outstanding
will be entitled to receive out of the assets of the Partnership (including
any Eligible Investments or amounts deposited in the Eligible
Investment Account) legally available for distribution to Partners after
satisfaction of liabilities of creditors as required by the Act before any
distribution of assets is made with respect to any other Interest in the
Partnership, an amount equal to the aggregate of the stated liquidation
preference of $50 per Preferred Security and accumulated and unpaid
Dividends (whether or not earned or declared) to the date of payment,
including any Additional Dividends accrued thereon (the "Liquidation
Distribution").

              (g)    Voting Rights -- Special General Partner.   (i)  If
(x) the Partnership 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 extend the interest payment period of the
Subordinated Debentures in accordance with the terms thereof), (y) an
Event of Default under the Subordinated Debentures occurs and is
continuing or (z) Corning is in default on any of its payment obligations
under the Guarantee, then the Holders, upon the affirmative vote of at
least a Majority in Liquidation Preference of the Preferred Securities,
will be entitled to appoint and authorize a special general partner (the
"Special General Partner") to enforce the Partnership's rights as a
creditor under the Subordinated Debentures, enforce the rights of the
Holders under the Guarantee and to declare and pay Dividends
(including Additional Dividends) on the Preferred Securities.  Upon the
appointment of a Special General Partner, the Special General Partner
shall be authorized, and shall to the extent of legally available funds,
declare and pay Dividends (including Additional Dividends) on the
Preferred Securities.  So long as the appointment of the Special General
Partner is effective, the Special General Partner shall manage the
business and affairs of the Partnership to the exclusion of the General
Partner.

              (ii)   In furtherance of the foregoing, and without
limiting the powers of any Special General Partner so appointed and for
the avoidance of any doubt concerning the powers of the Special
General Partner, any Special General Partner, in its own name and as
Special General Partner of the Partnership, may institute a proceeding,
including, without limitation, any suit in equity, an action at law or
other judicial or administrative proceeding, to enforce the Partnership's
rights directly against Corning, or any other obligor in connection with
such obligations on behalf of the Partnership, and may prosecute such
proceeding to judgment or final decree, and enforce the same against
Corning or any other obligor in connection with such obligations and
collect, out of the property, wherever situated, of Corning or any such
other obligor upon such obligations, the monies adjudged or decreed to
be payable in the manner provided by law.

              (iii)  For purposes of determining whether the
Partnership has failed to pay Dividends in full for 15 consecutive
months, Dividends shall be deemed to remain in arrears,
notwithstanding any payments in respect thereof, until full cumulative
Dividends have been or contemporaneously are declared and paid with
respect to all monthly Dividend periods terminating on or prior to the
date of payment of such full cumulative Dividends.  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% in Liquidation
Preference of the Preferred Securities will be entitled to convene such
meeting.  The provisions of Section 12.3 relating to the convening and
conduct of meetings of the Partners will apply with respect to any such
meeting.  Any Special General Partner so appointed shall vacate office
immediately if the Partnership (or Corning pursuant to the Guarantee)
shall have paid in full all accumulated and unpaid Dividends (including
any Additional Dividends) on the Preferred Securities or such Event of
Default or default, as the case may be, shall have been cured.  

              (h)    Voting Rights -- Certain Amendments.  (i)  If any
proposed amendment of this Agreement provides for, or the General
Partner otherwise proposes to effect, (x) any action that would
materially adversely affect the powers, preferences or rights of the
Preferred Securities, whether by way of amendment of this Agreement
or otherwise or (y) the liquidation, dissolution, winding-up or
termination of the Partnership (other than in connection with the
exchange of Corning Preferred Stock for all of the Preferred Securities
upon the occurrence of an Exchange Event), 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 Holders of not less than 66 2/3%
in Liquidation Preference of the Preferred Securities; provided, however,
that no such approval shall be required if the liquidation, dissolution,
winding-up or termination of the Partnership is proposed or initiated
pursuant to Section 11.2 hereof.
 
              (ii)   Any required approval of Holders may be given at
a separate meeting of such Holders convened for such purpose or
pursuant to written consent.  The Partnership will cause a notice of any
meeting at which Holders 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.  Each such notice will include a statement
setting forth (x) the date of such meeting or the date by which such
action is to be taken, (y) a description of any matter on which such
Holders are entitled to vote or upon which written consent is sought and
(z) instructions for the delivery of proxies or consents.  No vote or
consent of the Holders will be required for the Partnership to redeem
and cancel Preferred Securities in accordance with this Agreement.

              (iii)  Except as provided in this Section 6.2, Holders
shall have no voting rights, and the Holders may not remove the
General Partner.

              Section 6.3.  Conversion Rights of Preferred Securities. 
The Holders of Preferred Securities shall have the right, at their option,
to cause the Partnership to convert the Subordinated Debentures into
shares of Corning Common Stock and to have the Partnership distribute
such Corning Common Stock to the converting Holder in exchange for
such Holder's Preferred Securities at any time on and subject to the
following terms and conditions:

              (a)    The Preferred Securities will be convertible at the
office of the Transfer Agent for the Partnership and at such other office
or offices, if any, as the General Partner may designate, into Corning
Common Stock by directing the Partnership to convert Subordinated
Debentures on the basis of one Preferred Security per $50 principal
amount of Subordinated Debentures, which amount of Subordinated
Debentures shall then be converted into _____  shares of Corning
Common Stock (which is equivalent to a conversion price of $___ per
share of Corning Common Stock), subject to certain adjustments set
forth in the terms of the Subordinated Debentures.  

              (b)    In order to convert Preferred Securities into
Corning Common Stock through the Partnership, the Holder of such
Preferred Securities shall deliver an irrevocable Notice of Conversion to
the Partnership at the office referred to above setting forth the number
of Preferred Securities to be converted and the name or names in which
the shares of Corning Common Stock should be issued.  Upon receipt
of such notice, the Partnership shall notify Corning of its election to
convert a principal amount of Subordinated Debentures equal to the
aggregate stated liquidation preferences of the Preferred Securities
(exclusive of any Dividends, including Additional Dividends) specified
in such notice into shares of Corning Common Stock.  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 above, no payment, allowance
or adjustment shall be made by the Partnership or Corning upon any
conversion on account of any accumulated and unpaid Dividends
accrued on the Preferred Securities (including any Additional Dividends
accrued thereon) surrendered for conversion, or on account of any
accumulated and unpaid dividends on the shares of Corning Common
Stock issued upon such conversion.  Preferred Securities shall be
deemed to have been converted immediately prior to the close of
business on the day on which Notice of Conversion is delivered in
accordance with the foregoing provision (the "conversion date").  The
Person or Persons entitled to receive the Corning Common Stock
issuable upon conversion of the Subordinated Debentures shall be
treated for all purposes as the record holder or holders of such Corning
Common Stock at such time.   As promptly as practicable on or after
the conversion date, Corning shall issue and deliver at said office a
certificate or certificates for the number of full shares of Corning
Common Stock issuable upon such conversion, together with the cash
payment, if any, in lieu of any fraction of any share to the Person or
Persons entitled to receive the same, unless otherwise directed by the
Holder in the notice of conversion and the Partnership shall cause such
certificate or certificates to be distributed to the converting Holders.  

              (c)    Preferred Securities that have been called for
redemption will not be convertible after the close of business on the
second calendar day preceding the date fixed for redemption, unless the
Partnership defaults in making payment of the amount payable upon
such redemption.  Conversion rights will terminate upon the making of
an Exchange Election referred to in Section 6.4. 

              (d)    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 by Corning to the Partnership,
which in turn will make such payment to the Holder or Holders of
Preferred Securities so converted.

              (e)    Each share of Corning Common Stock issuable
upon conversion as contemplated by this Section 6.3 shall be issued
with one right to purchase Series A Junior Participating Preferred Stock
of Corning (or other securities in lieu thereof) pursuant to the Amended
Rights Agreement, dated as of October 4, 1989 (the "Rights
Agreement"), between Corning and Harris Trust and Savings Bank, as
Rights Agent, as such Rights Agreement may from time to time be
amended, or any similar rights issued to holders of Corning Common
Stock in addition thereto or in replacement therefor (such rights,
together with any additional or replacement rights, being collectively
referred to as the "Rights"), whether or not such Rights shall be
exercisable at such time, but only if such Rights are issued and
outstanding and held by other holders of Corning Common Stock (or
are evidenced by outstanding share certificates representing Corning
Common Stock) at such time and have not expired or been redeemed.

              (f)    Corning shall at all times reserve and keep
available out of its authorized and unissued Corning Common Stock,
solely for issuance upon the conversion of the Subordinated Debentures,
free from any preemptive or other similar rights, such number of shares
of Corning Common Stock as shall from time to time be issuable upon
the conversion of all the Subordinated Debentures then outstanding. 
Notwithstanding the foregoing, Corning shall be entitled to deliver upon
conversion of Subordinated Debentures, shares of Corning Common
Stock reacquired and held in the treasury of Corning (in lieu of the
issuance of authorized and unissued shares of Corning Common Stock),
so long as any such treasury shares are free and clear of all liens,
charges, security interests or encumbrances.  Any shares of Corning
Common stock issued upon conversion of the Subordinated Debentures
shall be duly authorized, validly issued and fully paid and non-
assessable.  The Partnership shall deliver the shares of Corning
Common Stock received upon conversion of the Subordinated
Debentures to the converting Holder free and clear of all liens, charges,
security interests and encumbrances, except for United States
withholding taxes.  Each of Corning and the Partnership shall prepare
and shall use its best efforts to obtain and keep in force such
governmental or regulatory permits or other authorizations as may be
required by law, and shall comply with all applicable requirements as to
registration or qualification of the Corning Common Stock (and all
requirements to list the Corning Common Stock issuable upon
conversion of Subordinated Debentures that are at the time applicable),
in order to enable Corning to lawfully issue Corning Common Stock to
the Partnership upon conversion of the Subordinated Debentures and the
Partnership to lawfully deliver the Corning Common Stock to each
Holder upon conversion of the Preferred Securities.

              (g)    Corning will pay any and all taxes that may be
payable in respect of the issue or delivery of shares of Corning
Common Stock on conversion of Subordinated debentures and the
delivery of the shares of Corning Common Stock by the Partnership
upon conversion of the Preferred Securities.  Corning shall not,
however, be required to pay any tax which may be payable in respect of
any transfer involved in the issue and delivery of shares of Corning
Common Stock in a name other than that in which the Preferred
Securities so converted were registered, and no such issue or delivery
shall be made unless and until the person requesting such issue has paid
to the Partnership the amount of any such tax, or has established to the
satisfaction of the Partnership that such tax has been paid.

              (h)    If Corning Common Stock is distributed by the
Partnership to the Holders after the Tax Event Date, the amount so
distributable shall be reduced by the amount of Additional Taxes
imposed on or payable by the Partnership as a result of such
distribution.
       
              (i)    Nothing in Section 6.3(g) shall limit the
requirement of the Partnership to withhold taxes pursuant to Section 4.4
or otherwise require the General Partner or the Partnership to pay any
amounts on account of such withholdings.



       
              Section 6.4   Optional Exchange for Corning Preferred
Stock.

              (a)    Upon the occurrence of an Exchange Event, the
Holders of a Majority in Liquidation Preference of the Preferred
Securities, voting as a class or by written consent, may, at their option,
cause the Partnership to exchange all (but not less than all) of the
Subordinated Debentures for Corning Preferred Stock at the Exchange
Price for shares of Corning Preferred Stock and distribute such stock to
the Holders in exchange for their Preferred Securities.  

              (b)    The following events are "Exchange Events":

              (i)    the failure of Holders to receive, for 15
       consecutive months, the full amount of Dividends on the
       Preferred Securities; or
              
              (ii)   a Tax Event.
              
              (c)    As soon as practicable, but in no event later than
30 days after the occurrence of an Exchange Event, the General Partner
shall convene a general meeting of the Holders (an "Exchange Election
Meeting") for the purpose of acting on the matter of whether to cause
the Partnership to exchange all of the Subordinated Debentures for the
Corning 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% in Liquidation Preference of the Preferred Securities
will be entitled to convene such Exchange Election Meeting.  Upon the
affirmative vote of the Holders of a Majority in Liquidation Preference
of the Preferred Securities at an Exchange Election Meeting or, in the
absence of such meeting, upon receipt by the Partnership of a written
consent signed by the Holders of a Majority in Liquidation Preference
of the 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, the Partnership will continue to pay Dividends on the Preferred
Securities without adjustment for Additional Taxes until the earlier of
(i) the date that is three months after the Notice Date and (ii) the
Meeting Date; provided, however, that thereafter Dividends on the
Preferred Securities shall be reduced by an amount equal to the
Holders' allocable share of Additional Taxes.  

              Holders, by becoming a party to this Agreement pursuant
to Section 2.9 of this Agreement, will be deemed to have agreed to be
bound by these optional exchange provisions in regard to the exchange
of Preferred Securities for Corning Preferred Stock  pursuant to the
terms described above.

              (d)    Corning shall at all times reserve and keep
available out of its authorized and unissued Corning Preferred Stock,
solely for issuance upon the exchange of Subordinated Debentures, free
from any preemptive or other similar rights, such number of shares of
Corning Preferred Stock as shall from time to time be issuable upon the
exchange of all the Subordinated Debentures then outstanding.  Each of
Corning and the Partnership shall prepare and shall use its best efforts
to obtain and keep in force such governmental or regulatory permits or
other authorizations as may be required by law, and shall comply with
all applicable requirements as to registration or qualification of the
Corning Preferred Stock in order to enable Corning to lawfully issue the
Corning Preferred Stock upon exchange of the Subordinated Debentures
and the Partnership to lawfully deliver Corning Preferred Stock upon
exchange of the Preferred Securities.  All shares of Corning Preferred
Stock issued upon conversion of the Subordinated Debentures shall be
duly authorized, validly issued and fully paid and non-assessable and
the terms of the Corning Preferred Stock shall be valid and binding on
Corning.  The Partnership shall deliver the shares of Corning Preferred
Stock received upon exchange of the Preferred Securities to the
exchanging Holder, free and clear of all liens, charges, security interests
and encumbrances.

              (e)    Corning will pay any and all taxes that may be
payable in respect of the issue or delivery of shares of Corning 
Preferred Stock upon exchange of the Subordinated  Debentures and 
the delivery of the shares of Corning Preferred Stock by the 
Partnership upon exchange of the Preferred Securities.  Corning 
shall not, however, be required to pay any tax which may be 
payable in respect of any transfer involved in the issue and 
delivery of Corning Preferred Stock in a name other  than that
in which Preferred Securities so exchanged were registered, and no such
issue or delivery shall be made unless and until the person requesting
such issue has paid to the Partnership the amount of any such tax, or
has established to the satisfaction of the Partnership that such tax has
been paid.

              (f)    Preferred Securities shall be deemed to have been
exchanged immediately prior to the close of business on the day on
which the Exchange Election is made.  The Person or Persons entitled
to receive the Corning Preferred Stock issuable upon exchange of the
Preferred Securities shall be treated for all purposes as the record holder
or holders of such Corning Preferred Stock at such time.  As promptly
as practicable on or after the date on which the Exchange Election is
made, Corning shall issue and deliver to the Partnership for distribution
to the Persons entitled thereto, a certificate or certificates for the
number of full shares of Corning Preferred Stock issuable upon such
exchange and the Partnership shall promptly distribute such certificates
to the Persons entitled thereto.

              (g)    The terms of the Corning Preferred Stock
exchanged for the Preferred Securities shall provide that all accumulated
and unpaid Dividends (including any Additional Dividends thereon) that
are not paid by the Partnership or Corning pursuant to the Guarantee
shall be treated as accumulated and unpaid dividends on such Corning
Preferred Stock.
       
              (h)    If Corning Preferred Stock is distributed by the
Partnership to the Holders after the Tax Event Date, the amount so
distributable shall be reduced by the amount of Additional Taxes
imposed on or payable by the Partnership as a result of such
distribution.

              (i)    Nothing in Section 6.4(e) shall limit the
requirement of the Partnership to withhold taxes pursuant to Section 4.4
or otherwise require the General Partner or the Partnership to pay any
amounts on account of such withholdings.

                              ARTICLE VII

of which the General Partner reasonably believes is not in the best
interests of the Partnership or is adverse to the interests of the
Partnership or which the Partnership or the General Partner is required
by law or by an agreement with any Person to keep confidential.

              (c)    Within three months after the close of each Fiscal
Year, the General Partner shall transmit to each Partner, a statement
indicating such Partner's share of each item of Partnership income, gain,
loss, deduction or credit for such Fiscal Year for federal income tax
purposes.

              Section 7.2   Accounting Method.  For both financial

accrual method of accounting applied in a consistent manner and shall
reflect all Partnership transactions and be appropriate and adequate for
the Partnership's business.

              Section 7.3   Annual Audit.  As soon as practical after
the end of each Fiscal Year, but not later than 90 days after such end,
the financial statements of the Partnership shall be audited by a firm of
independent certified public accountants selected by the General Partner,
and such financial statements shall be accompanied by a report of such
accountants containing their opinion.  The cost of such audits will be an
expense of the Partnership.

              Section 9.3   Expenses Payable by General Partner.  

              (a)    The General Partner hereby agrees to pay to each
Person or entity to whom the Partnership is now or hereafter becomes

arising under Sections 7.3, 9.5 and 9.7 of this Agreement and those in
respect of certain Additional Taxes as provided in clause (b) below, but
excluding payment obligations of Corning or the Partnership to Holders
of the Preferred Securities in such Holders' capacities as Holders of
such Preferred Securities, such obligations being separately guaranteed
under the Guarantee) (the "Beneficiaries") the full payment of such
indebtedness and liabilities, when and as due.  This agreement is
intended to be for the benefit of and to be enforceable by all such
Beneficiaries whether or not such Beneficiaries have received notice
hereof.

              (b)    The General Partner will pay any and all
Additional Taxes, liabilities, costs and expenses with respect to such
Additional Taxes of the Partnership for the period from the formation of

this Agreement, (a) the General Partner shall not be personally liable for
the return of any portion of the capital contributions (or any return
thereon) of the Limited Partners; (b) the return of such capital

the Partnership; and (c) the General Partner shall not be required to pay
to the Partnership or to any Limited Partner any deficit in any Limited
Partner's Capital Account upon dissolution or otherwise.  Other than as
provided in Sections 6.3 and 6.4 of this Agreement or under the Act, no
Limited Partner shall have the right to demand or receive property other

damage or claim incurred by reason of any act or omission performed
or omitted by such Indemnified Person in good faith on behalf of the
Partnership and in a manner reasonably believed to be within the scope
of the authority conferred on such Indemnified Person by this
Agreement or by law except that an Indemnified Person shall be liable
for any such loss, damage or claim incurred by reason of such
Indemnified Person's bad faith recklessness or willful misconduct.

              (b)    An Indemnified Person shall be fully protected in
relying in good faith upon the records of the Partnership and upon such
information, opinions, reports or statements presented to the Partnership
by any Person as to matters the Indemnified Person reasonably believes
are within such other Person's professional or expert competence and
who has been selected with reasonable care by or on behalf of the
Partnership, including information, opinions, reports or statements as to
the value and amount of the assets, liabilities, profits, losses, or any
other facts pertinent to the existence and amount of assets from which
distributions to Partners might properly be paid.

              Section 9.6   Fiduciary Duty.

              (a)    To the extent that, at law or in equity, an
Indemnified Person has duties (including fiduciary duties) and liabilities
relating thereto to the Partnership or to any other Covered Person, an
Indemnified Person acting under this Agreement shall not be liable to
the Partnership or to any other Covered Person for its good faith
reliance on the provisions of this Agreement.  The provisions of this
Agreement, to the extent that they restrict the duties and liabilities of an
Indemnified Person otherwise existing at law or in equity, are agreed by
the parties hereto to replace such other duties and liabilities of such
Indemnified Person.

              (b)    Unless otherwise expressly provided herein, (i)
whenever a conflict of interest exists or arises between Covered
Persons, or (ii) whenever this Agreement or any other agreement
contemplated herein or therein provides that an Indemnified Person shall
act in a manner that is, or provides terms that are, fair and reasonable to
the Partnership or any Partner, the Indemnified Person shall resolve
such conflict of interest, taking such action or providing such terms,
considering in each case the relative interest of each party (including its
own interest) to such conflict, agreement, transaction or situation and
the benefits and burdens relating to such interests, any customary or
accepted industry practices, and any applicable generally accepted
accounting practices or principles.  In the absence of bad faith by the
Indemnified Person, the resolution, action or terms so made, taken or
provided by the Indemnified Person shall not constitute a breach of this
Agreement or any other agreement contemplated herein or of any duty
or obligation of the Indemnified Person at law or in equity or otherwise.

              (c)    Whenever in this Agreement an Indemnified
Person is permitted or required to make a decision (i) in its "discretion"
or under a grant of similar authority, the Indemnified Person shall be
entitled to consider only such interests and factors as it desires,
including its own interests, and shall have no duty or obligation to give
any consideration to any interest of, or factors affecting, the Partnership
or any other Person, or (ii) in its "good faith" or under another express
standard, the Indemnified Person shall act under such express standard
and shall not be subject to any other or different standard imposed by
this Agreement or other applicable law.

              Section 9.7   Indemnification.

              (a)    To the fullest extent permitted by applicable law,
the Partnership shall indemnify and hold harmless each Indemnified
Person from and against any loss, damage or claim incurred by such
Indemnified Person by reason of any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the
Partnership and in a manner reasonably believed to be within the scope
of authority conferred on such Indemnified Person by this Agreement,
except that no Indemnified Person shall be entitled to be indemnified in
respect of any loss, damage or claim incurred by such Indemnified
Person by reason of gross negligence or willful misconduct with respect
to such acts or omissions; provided, however, that any indemnity under
this Section 9.7 shall be provided out of and to the extent of Partnership
assets only, and no Covered Person shall have any personal liability on
account thereof.

              (b)    To the fullest extent permitted by applicable law,
expenses (including legal fees) incurred by an Indemnified Person in
defending any claim, demand, action, suit or proceeding shall, from
time to time, be advanced by the Partnership prior to the final
disposition of such claim, demand, action, suit or proceeding upon
receipt by the Partnership of an undertaking by or on behalf of the
Indemnified Person to repay such amount if it shall be determined that
the Indemnified Person is not entitled to be indemnified as authorized in
Section 9.7(a).

              Section 9.8   Investment Company or Tax Actions.  The
General Partner is authorized and directed to conduct its affairs and to
operate the Partnership in such a way that the Partnership would 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 or this
Agreement, and that does not materially and adversely affect the
interests of Holders, that the General Partner determines in its discretion
to be necessary or desirable for such purposes.         

              Section 9.9   Outside Businesses.  Any Partner or
Affiliate thereof may engage in or possess an interest in other business
ventures of any nature or description, independently or with others,
similar or dissimilar to the business of the Partnership, and the
Partnership and the Partners shall have no rights by virtue of this
Agreement in and to such independent ventures or the income or profits
derived therefrom and the pursuit of any such venture, even if
competitive with the business of the Partnership, shall not be deemed
wrongful or improper.  No Partner or Affiliate thereof shall be obligated
to present any particular investment opportunity to the Partnership even
if such opportunity is of a character that, if presented to the Partnership,
could be taken by the Partnership, and any Partner or Affiliate thereof
shall have the right to take for its own account (individually or as a
partner or fiduciary) or to recommend to others any such particular
investment opportunity.

              Section 9.10  Limits on General Partner's Powers.  (a) 
Anything in this Agreement to the contrary notwithstanding, the General
Partner (or, upon appointment pursuant to Section 6.2(g), the Special
General Partner) shall not cause or permit the Partnership to

              (i)    acquire any assets other than as expressly
       provided herein;

              (ii)   do any act which would make it impractical or
       impossible to carry on the ordinary business of the Partnership;

              (iii)  possess Partnership property for other than a
       Partnership purpose;

              (iv)   admit a Person as a Partner, except as expressly
       provided in this Agreement;

              (v)    make any loans to the General Partner or its
       Affiliates, other than loans represented by the Subordinated
       Debentures;

              (vi)   perform any act that would subject any Limited
       Partner to liability as a general partner in any jurisdiction;

              (vii)  engage in any activity that is not consistent with
       the purposes of the Partnership, as set forth in Section 2.3;

              (viii) without the written consent of not less than 66
       2/3% in Liquidation Preference of the Preferred Securities have
       an order for relief entered with respect to the Partnership or
       commence a voluntary case under any applicable bankruptcy,
       insolvency or other similar law now or hereafter in effect, or
       consent to the entry of an order for relief in an involuntary case
       under any such law, or consent to the appointment of or taking
       possession by a receiver, trustee or other custodian for all or a
       substantial part of the Partnership's property, or make any
       assignment for the benefit of creditors of the Partnership; or

              (ix)   borrow money or become liable for the
       borrowings of any third party or to engage in any financial or
       other trade or business.
 
              (b)    So long as the Subordinated Debentures are held
by the Partnership, the General Partner shall not:

              (i) direct the time, method and place of conducting any
       proceeding for any remedy available to the Special General
       Partner, or 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
       Subordinated Debentures,

               (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 Fiscal Agency Agreement or the Subordinated
       Debentures without, in each case, obtaining the prior approval of
       the Holders of not less than 66 2/3% in Liquidation Preference
       of the Preferred Securities, provided, however, that where a
       consent under the Subordinated Debentures would require the
       consent of each holder of Subordinated Debentures affected
       thereby, no such consent shall be given by the General Partner
       without the prior consent of each Holder of Preferred Securities. 
       

              (c)    The General Partner shall not revoke any action
previously authorized or approved by the Special General Partner or by
a vote of Holders without the approval of the Holders of not less than
66 2/3% in Liquidation Preference of the Preferred Securities. The
General Partner shall notify all Holders of any notice of default received
from the Fiscal Agent with respect to the Subordinated Debentures.

              Section 9.11  Tax Matters Partner.  

              (a)    For purposes of Code Section 6231(a)(7), the "Tax

proceeding.

accordance with Section 754 of the Code.

certified public accountants which shall prepare all federal, state, local
or other tax returns (including information returns) of the Partnership, as
required by law, and the Schedule K-1's or any successor or similar
forms or schedules required by law.

              Section 9.12    Consolidation, Merger or Sale of Assets. 


              (a)    Corning may not merge or consolidate with or
into another entity or permit another entity to merge or consolidate with
or into, or sell, transfer or lease all or substantially all of its assets to
another entity (each such event, a "Transaction") unless (i) at the time
of such Transaction, 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 Transaction, (ii) the survivor of such merger or
consolidation or the entity to which Corning's assets are sold,

Corning's assets that includes Corning's Interest in the Partnership,
Corning has obtained the consent of the Holders of not less than 66
2/3% in the Liquidation Preference of the Preferred Securities to the
sale, transfer or lease of its Interest in the Partnership .

              (b)    In addition, the General Partner shall not cause or
allow the Partnership to enter into a Transaction, except as described

Agreement.  The Partnership may, for purposes of changing its state of
domicile in order to avoid a Tax Event or 1940 Act consequences
adverse to Corning, itself or the Holders, without the consent of the
Holders, merge or consolidate 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 the Partnership 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 the Partnership, (ii) Corning

by any nationally recognized statistical rating organization, as that term

interest in the new entity), (vi) prior to such Transaction, Corning has
received an opinion of nationally recognized independent counsel to the
Partnership 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 Transaction, Corning and such successor
entity will be in compliance with the 1940 Act without registering

                               ARTICLE X

                  TRANSFERS OF INTERESTS BY PARTNERS

              Section 10.1  Transfer of Interests.  

              (a)    Preferred Securities shall be freely transferable by
a Holder.

              (b)    Except as provided in the succeeding sentence, the
General Partner may not assign or transfer its Interest in the Partnership
in whole or in part unless, prior to such assignment or transfer, the
General Partner has obtained the consent of the Holders of not less than
66 2/3% in Liquidation preference of the Preferred Securities.  The
General Partner may assign or transfer its interest in the Partnership
without such consent only to an entity that is the survivor of a merger
or consolidation of the General Partner in a transaction that meets the
requirements of Section 9.12(a).  "Permitted Successor" shall mean an
entity that is an assignee or transferee of the Interest of the General
Partner as permitted by this Section 10.1(b).

              (c)    Except as provided above, no Interest shall be
transferred, in whole or in part, except in accordance with the terms and

transfer of any Interest not made in accordance with this Agreement
shall be null and void.

LP Certificates to be issued in the name of the designated transferee or
transferees.  Every LP Certificate surrendered for registration of transfer
shall be accompanied by a written instrument of transfer in form
satisfactory to the General Partner duly executed by the Preferred
Security Holder or his or her attorney duly authorized in writing.  Each
LP Certificate surrendered for registration of transfer shall be canceled
by the General Partner.  A transferee of an LP Certificate shall be
admitted to the Partnership as a Limited Partner and shall be entitled to
the rights and subject to the obligations of a Preferred Security Holder
hereunder upon the receipt by a transferee of an LP Certificate.

              Section 10.3  Persons Deemed Preferred Security
Holders.  The Partnership may treat the Person in whose name any LP
Certificate shall be registered on the books and records of the
Partnership as the sole holder of such LP Certificate and of the
Preferred Securities represented by such LP Certificate for purposes of
receiving Dividends and for all other purposes whatsoever and,
accordingly, shall not be bound to recognize any equitable or other
claim to or interest in such LP Certificate or in the Preferred Securities
represented by such LP Certificate on the part of any other Person,
whether or not the Partnership shall have actual or other notice thereof.

              Section 10.4  Book Entry Interests.  The LP Certificates,
on original issuance, will be issued in the form of a global LP
Certificate or LP Certificates representing the Book Entry Interests, to
be delivered to DTC, the initial Clearing Agency, by, or on behalf of,
the Partnership. Such LP Certificate or LP Certificates shall initially be
registered on the books and records of the Partnership in the name of
Cede & Co., the nominee of DTC, and no Preferred Security Owner
will receive a definitive LP Certificate representing such Preferred
Security Owner's interests in such LP Certificate, except as provided in
Section 10.6.  Unless and until definitive, fully registered LP
Certificates (the "Definitive LP Certificates") have been issued to the
Preferred Security Owners pursuant to Section 10.6:

              (i)    The provisions of this Section shall be in full
       force and effect;

              (ii)   The Partnership, the General Partner and any
       Special General Partner shall be entitled to deal with the
       Clearing Agency for all purposes of this Agreement (including
       the payment of Dividends, Redemption Price and liquidation
       proceeds on the LP Certificates and receiving approvals, votes or
       consents hereunder) as the Preferred Security Holder and the sole
       holder of the LP Certificates and shall have no obligation to the
       Preferred Security Owner;

              (iii)  None of the Partnership, the General Partner, any
       Special General Partner or any agent of the General Partner, the
       Partnership or any Special General Partner shall have any
       liability with respect to or responsibility for the records of the
       Clearing Agency.

              Section 10.5  Notices to Clearing Agency.  Whenever a
notice or other communication to the Preferred Security Holders is
required under this Agreement, unless and until Definitive LP
Certificates shall have been issued to the Preferred Security Owners
pursuant to Section 10.6, the General Partner and any Special General
Partner shall give all such notices and communications specified herein
to be given to the Preferred Security Holders to the Clearing Agency,
and shall have no obligations to the Preferred Security Owners.

              Section 10.6  Definitive LP Certificates.  If (i) the
Clearing Agency elects to discontinue its services as securities
depository, (ii) the Partnership elects to terminate the book entry system
through the Clearing Agency, or (iii) there is an Event of Default under
the Subordinated Debentures, then Definitive LP Certificates shall be
prepared by the Partnership.  Upon surrender of the global LP
Certificate or LP Certificates representing the Book Entry Interests by
the Clearing Agency, accompanied by registration instructions, the
General Partner shall cause Definitive LP Certificates to be delivered to
Preferred Security Owners in accordance with the instructions of the
Clearing Agency.  Neither the General Partner nor the Partnership shall
be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such
instructions.  Any Person receiving a Definitive LP Certificate in
accordance with this Article X shall be admitted to the Partnership as a
Limited Partner upon receipt of such Definitive LP Certificate and shall
be registered on the books and records of the Partnership as a Preferred
Security Holder. The Definitive LP Certificates shall be printed,
lithographed or engraved or may be produced in any other manner as
may be required by any national securities exchange on which the
Preferred Securities may be listed and is reasonably acceptable to the
General Partner, as evidenced by its execution thereof.

                LIQUIDATION AND DISTRIBUTION OF ASSETS

              Section 11.l  Withdrawal of Partners.  The General
Partner shall not at any time retire or withdraw from the Partnership
except as otherwise permitted hereunder.   If the General Partner retires
or withdraws in contravention of this Section 11.1, it shall indemnify,
defend and hold harmless the Partnership and the other Partners from
and against any losses, expenses, judgments, fines, settlements or
damages suffered or incurred by the Partnership or such other Partners
arising out of or resulting from such retirement or withdrawal.

              Section 11.2  Dissolution of the Partnership.

              (a)    The Partnership shall not be dissolved by the
admission of Partners in accordance with the terms of this Agreement. 
Except as provided in Section 11.2(b)(ii), the death, retirement,
resignation, expulsion, bankruptcy or dissolution of a Partner, or the
occurrence of any other event which terminates the Interest of a Partner
in the Partnership, shall not cause the Partnership to be dissolved and its
affairs wound up so long as the Partnership at all times has at least two
Partners.  Upon the occurrence of any such event, the business of the
Partnership shall be continued without dissolution.

              (b)    The Partnership shall be dissolved and terminated
and its affairs shall be wound up upon the earliest to occur of any of
the following events:

              (i)    The expiration of the term of the Partnership, as
       provided in Section 2.4 of this Agreement;

              (ii)   Upon the bankruptcy, insolvency or dissolution of
       the General Partner;

              (a)    In the event of the dissolution of the Partnership
for any reason, the General Partner (or, if the Partnership is dissolved
pursuant to Section 11.2(b)(ii), then a liquidating agent appointed by
Holders of not less than 66 2/3% in Liquidation Preference of the
Preferred Securities (the General Partner or such person so appointed is
hereinafter referred to as the "Liquidator")) shall commence to wind up
the affairs of the Partnership and to liquidate the Partnership's assets,
including the Partnership's Eligible Investments and/or amounts
deposited in the Eligible Investment Account; provided, however, that a
reasonable time shall be allowed for the orderly liquidation of the assets
of the Partnership and the satisfaction of liabilities to creditors so as to
enable the Partners to minimize the normal losses attendant upon
liquidation.  The Partners shall continue to share all income, losses and
distributions during the period of liquidation in accordance with Articles
IV and V.  Subject to the provisions of this Article XI, the Liquidator
shall have full right and unlimited discretion to determine the time,
manner and terms of any sale or sales of Partnership property pursuant
to such liquidation, giving due regard to the activity and condition of
the relevant market and general financial and economic conditions.

              (b)    The Liquidator shall have all of the rights and
powers with respect to the assets and liabilities of the Partnership in
connection with the liquidation and termination of the Partnership that
the General Partner would have with respect to the assets and liabilities
of the Partnership during the term of the Partnership, and the Liquidator
is hereby expressly authorized and empowered to execute any and all
documents necessary or desirable to effectuate the liquidation and
termination of the Partnership and the transfer of any assets.

              (c)    Notwithstanding the foregoing, a Liquidator that is
not the General Partner shall not be deemed a Partner in this Partnership
and shall not have any of the economic interests in the Partnership of a
Partner; and such Liquidator may be compensated for its services to the
Partnership at normal, customary and competitive rates for its services
to the Partnership as reasonably determined by all the Limited Partners.

              Section 11.4  Distribution in Liquidation.  Subject to
Section 9.3, the proceeds of liquidation shall be applied in the following
order of priority (and without regard to the provisions of Section 17-804
of the Act):

              (i)    to creditors of the Partnership, including Preferred
       Security Holders who are creditors, to the extent otherwise
       permitted by law, in satisfaction of the liabilities of the
       Partnership (whether by payment or the making of reasonable
       provision for payment thereof), other than liabilities for
       distributions (including Dividends) to Partners; and

              (ii)   following any allocations required under Section
       4.1(c) of this Agreement, to the Partners in proportion to the
       Partner's positive Capital Account balances.

              Section 11.5  Rights of Limited Partners.  Each Limited
Partner shall look solely to the assets of the Partnership for all
distributions with respect to the Partnership and such Partner's capital
contribution (including returns thereof), and such Partner's share of
profits or losses thereof, and shall have no recourse therefor (upon
dissolution or otherwise) against the General Partner, except under the
Guarantee.  Except as provided in Sections 6.3 and 6.4 of this
Agreement, no Partner shall have any right to demand or receive
property other than cash upon dissolution and termination of the
Partnership.

              Section 11.6  Termination.  The Partnership shall
terminate when all of the assets of the Partnership shall have been
disposed of and the assets shall have been distributed as provided in
Section 11.4.  The Liquidator shall then execute and cause to be filed a
certificate of cancellation of the Partnership.


                              ARTICLE XII

                        AMENDMENTS AND MEETINGS

              Section 12.1  Amendments.  Except as provided by
Section 6.2(h), this Agreement may be amended by a written instrument
executed by the General Partner without the consent of any Limited
Partner; provided, however, that no amendment shall be made, and any
such purported amendment shall be void and ineffective, to the extent
the result thereof would be to cause the Partnership to be treated as
anything other than a partnership for purposes of United States income
taxation or require the Partnership to register under the 1940 Act.

              Section 12.2  Amendment of Certificate.  In the event
this Agreement shall be amended pursuant to Section 12.1, the General
Partner shall amend the Certificate to reflect such change if it deems
such amendment of the Certificate to be necessary or appropriate.

              Section 12.3  Meetings of Partners.

              (a)    Meetings of the Limited Partners who are Holders
may be called at any time by the General Partner to consider and act on
any matter on which Limited Partners are entitled to act under the terms
of this Agreement or the Act.  The General Partner shall call a meeting
of Holders if directed to do so by Holders of not less than 10% in
Liquidation Preference as permitted by this Agreement.  Such direction
shall be given by delivering to the General Partner a request in writing
stating that the signing Limited Partners desire to call a meeting and
indicating the general or specific purpose for which the meeting is to be
called. 

              (b)    Notice of any such meeting shall be given to all
Partners not less than seven Business Days nor more than 60 days prior
to the date of such meeting.  Each such notice shall set forth the date,
time and place of the meeting, a description of the any matter on which
Holders are entitled to vote and instructions for the delivery of proxies
or written consents.  

              (c)    Any action that may be taken at a meeting of the
Limited Partners may be taken without a meeting if a consent in writing
setting forth the action so taken is signed by Limited Partners owning
not less than the minimum Interests that would be necessary to
authorize or take such action at a meeting in which all Limited Partners
having a right to vote thereon were present and voting.  Prompt notice
of the taking of action without a meeting shall be given to the Limited
Partners entitled to vote who have not consented in writing.  The
General Partner may provide that any written ballot submitted to the
Limited Partners for the purpose of taking any action without a meeting
shall be returned to the Partnership within a specified time.   

              (d)    Each Partner may authorize any Person to act for
it by proxy on all matters as to which a Partner is entitled to participate,
including waiving notice of any meeting, or voting or participating at a
meeting.  Every proxy must be signed by the Partner or its
attorney-in-fact.  No proxy shall be valid after the expiration of 11
months from the date thereof unless otherwise provided in the proxy. 
Every proxy shall be revocable at the pleasure of the Partner executing
it.  

              (e)    Each meeting of Partners shall be conducted by
the General Partner or by such other Person that the General Partner
may designate.

              (f)    The General Partner may establish all other
reasonable procedures relating to meetings of Partners or the giving of
written consents, in addition to those expressly provided, including
notice of time, place or purpose of any meeting at which any matter is
to be voted on by any Partners, waiver of any such notice, action by
consent without a meeting, the establishment of a record date, quorum
requirements, voting in person or by proxy or any other matter with
respect to the exercise of any such right to vote.

relating to the Preferred Securities.  Capitalized terms used herein but
not defined herein shall have the meaning given them in the Limited
Partnership Agreement.  The Holder is entitled to the benefits of the
Guarantee Agreement of Corning Incorporated, a New York corporation
("Corning"), dated as of _______,1994 (the "Guarantee") to the extent
provided therein.  The partnership will furnish a copy of the Limited
Partnership Agreement and the Guarantee to the Holder without charge

have agreed (i) to be bound by the provisions of the Limited Partnership
Agreement, including the provisions of such Agreement concerning the
exchange of the Preferred Securities for Corning Preferred Stock and
(ii) that the Subordinated Debentures acquired by the Partnership with
the proceeds from the issuance of the Preferred Securities are
subordinated and junior in right of payment to all Senior Indebtedness
of Corning as and to the extent provided in the Subordinated Debentures
and (iii) that the Guarantee ranks subordinate and junior in right of
payment to all liabilities of Corning as and to the extent provided in the
Guarantee.  Upon receipt of this certificate, the Holder is admitted to
the partnership as a Limited Partner, is bound by the Limited
Partnership Agreement and is entitled to the benefits thereunder.

                                 OF

                   THE CERTIFICATE OF INCORPORATION

           Under Section 805 of the Business Corporation Law




                WE, JAMES R. HOUGHTON and A. JOHN PECK,
JR., being, respectively, the Chairman and the Secretary of
Corning Incorporated, a corporation organized under the laws
of the State of New York, DO HEREBY CERTIFY as follows:

                FIRST:  The name of the Corporation is Corning
Incorporated.  The Corporation was formed under the name
Corning Glass Works.

                SECOND:  The Certificate of Incorporation of the
Corporation (being the Preliminary Certificate of Consolidation
Forming the Corporation) was filed in the Office of the
Secretary of State of the State of New York on December 24,
1936.

                THIRD:  The said Certificate of Incorporation, as
heretofore amended and restated, is hereby amended pursuant
to Section 801(b) of the Business Corporation Law by the
addition of the following provisions stating the number,
designation, relative rights, preferences and limitations of a
series of Series Preferred Stock, par value $100 per share, as
fixed by the Board of Directors of the Corporation before the
issuance of such shares, such provisions so added to be
designated as paragraph 4C of the Restated Certificate of
Incorporation of the Corporation and to read as follows:

                                
4C.  Series C Cumulative Convertible Preferred Stock

                SECTION 1.  Designation and Amount; Special
Purpose; Restriction on Senior Series.  

                (A) The shares of this series of Preferred Stock shall be
designated as "Series C Cumulative Convertible Preferred
Stock" (the "Series C Preferred Stock") and the number of
shares constituting such series shall be           with a par value
of $100 per share.

                (B) Shares of Series C Preferred Stock shall be issued
only upon exchange of all of the __% convertible subordinated
debentures due _____, 2024 of the Corporation (the
"Subordinated Debentures") by Corning Delaware, L.P., a
Delaware limited partnership ("Corning Delaware") pursuant to
a valid exchange election (the "Exchange Election") by the
holders of a majority of the aggregate liquidation preference of
preferred securities, liquidation preference of $50 per security,
of Corning Delaware (the "Corning Delaware Preferred
Securities").

                (C) So long as any Corning Delaware Preferred
Securities are outstanding, the Corporation shall not issue any
other class or series of capital stock ranking senior as to the
payment of dividends or amounts upon liquidation, dissolution
or winding-up to the Series C Preferred Stock without the
approval of the holders of not less than 66--% of the aggregate
liquidation preference of the Corning Delaware Preferred
Securities then outstanding.

                SECTION 2.  Dividends and Distributions.  

                (A) (1)  The holders of shares of Series C Preferred
Stock shall be entitled to receive, when, as and if declared by
the Board of Directors of the Corporation out of funds legally
available therefor, cumulative cash dividends in an amount per
share per annum equal to $_____ (equivalent to a rate per
annum of       % of the stated liquidation preference of $100
per share of Series C Preferred Stock), calculated on the basis
of a 360-day year consisting of 12 months of 30 days each,
and for any period shorter than a full monthly dividend period,
dividends will be computed on the basis of the actual number
of days elapsed in such period, and payable in United States
dollars monthly in arrears on the last day of each calendar
month of each year. 

                (2) Dividends, when, as and if declared by the Board of
Directors of the Corporation out of funds legally available
therefor, must be paid on the last day of each month.  Such
dividends will accrue and be cumulative whether or not they
have been earned or declared and whether or not there are
funds of the Corporation legally available for the payment of
dividends.  Dividends on the Series C Preferred Stock shall be
cumulative from the date of the Exchange Election.  Accrued
but unpaid interest on the Subordinated Debentures, if any, on
the date of the issuance of the Series C Preferred Stock in
exchange for such Subordinated Debentures shall constitute,
and be treated as, accumulated and unpaid dividends on the
Series C Preferred Stock; provided, however, that the amount
which shall constitute such accumulated and unpaid dividends
on the Corning Series C Preferred Stock shall be neither less
than nor greater than the amount of accumulated and unpaid
dividends (including Additional Dividends), if any, on the
Preferred Securities on the date of such Exchange Election. 
The record date for each dividend payment date shall be the
Business Day (as defined below) immediately preceding such
dividend payment date.  In the event that any date on which
dividends are payable on the Series C Preferred Stock is not a
day other than a day on which banking institutions in The City
of New York or Chicago are authorized or required by law to
close (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 shall be made on the immediately preceding Business
Day, in each case with the same force and effect as if made on
such date.  

                (B)  In the event that full cumulative dividends on
the Series C Preferred Stock have not been declared and paid
or set apart for payment when due, then the Corporation shall
not, and shall not permit any majority-owned subsidiary to
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)]. 

                When dividends are not paid in full, all dividends
declared upon the Series C Preferred Stock and all dividends
declared upon any Pari Passu Stock (as defined herein) shall be
declared ratably in proportion to the respective amounts of
dividends accumulated and unpaid on the Series C Preferred
Stock and accumulated and unpaid on such Pari Passu Stock. 
"Pari Passu Stock" means the Corporation's Series B
Cumulative Convertible Preferred Stock, par value $100 per
share (the "Series B Preferred Stock"), and any preference
stock or preferred stock of the Corporation, or any guarantee
now or hereafter entered into by the Corporation in respect of
any preferred or preference stock of any affiliate of the
Corporation, ranking, in such case, as to the payment of
dividends and amounts upon liquidation, dissolution and
winding-up on a parity with the Series B Preferred Stock. 
"Junior Stock" means Common Stock, the Series A Preferred
Stock, par value $100 per share, of the Corporation and any
other class or series of capital stock of the Corporation or any
of its affiliates which by its express terms ranks junior in the
payment of dividends or amounts upon liquidation, dissolution
or winding-up to the Series C Preferred Stock.


                SECTION 3.  Voting Rights.  

                (A) In the event that full cumulative dividends on the
Series C Preferred Stock have not been paid for 18 monthly
dividend periods, the number of directors of the Corporation
constituting the entire Board of Directors shall be increased by
two persons and the holders of the Series C Preferred Stock
shall have the right to elect such persons to fill such positions
at any annual meeting of shareholders or special meeting held
in place thereof, or at a special meeting of the holders of the
Series C Preferred Stock called as hereinafter provided. 
Whenever all arrears in dividends on the Series C Preferred
Stock then outstanding shall have been paid and dividends
thereon for the current monthly period shall have been paid or
declared and set apart for payment, then the right of the
holders of the Series C Preferred Stock to elect such additional
two directors shall cease (but subject always to the same
provisions for the vesting of such voting rights in the case of
any similar future arrearages in dividends), and the terms of
office of all persons elected as directors by the holders of the
Series C Preferred Stock shall forthwith terminate and the
number of directors of the Corporation constituting the entire
Board of Directors shall be reduced accordingly.  At any time
after such voting power shall have been so vested in the
holders of shares of the Series C Preferred Stock, the Secretary
of the Corporation may, and upon the written request of any
holder of Series C Preferred Stock (addressed to the Secretary
at the principal office of the Corporation) shall, call a special
meeting of the Series C Preferred Stock for the election of the
two directors to be elected by them as herein provided, such
call to be made by notice similar to that provided in the by-
laws for a special meeting of the shareholders or as required
by law.  If any such special meeting required to be called as
above provided shall not be called by the Secretary within 20
days after receipt of any such request, then any holder of
Series C Preferred Stock may call such meeting, upon the
notice above provided, and for that purpose shall have access
to the stock books and records of the Corporation.  The
directors elected at any such special meeting shall hold office
until the next annual meeting of the shareholders or special
meeting held in place thereof if such office shall not have
previously terminated as above provided.  In case any vacancy
shall occur among the directors elected by the holders of the
Series C Preferred Stock, a successor shall be elected by the
Board of Directors to serve until the next annual meeting of
the shareholders or special meeting held in place thereof upon
the nomination of the then remaining director elected by the
holders of the Series C Preferred Stock or the successor of
such remaining director.

                (B) Except as otherwise required by law or set forth
herein, holders of Series C Preferred Stock shall have no
special voting rights and their consent shall not be required for
the taking of any corporate action.  So long as any shares of
Series C Preferred Stock are outstanding, the consent of the
holders of not less than 66 2/3% of the outstanding shares of
Series C Preferred Stock, given in person or by proxy either at
a regular meeting or at a special meeting called for that
purpose, at which the holders of Series C Preferred Stock shall
vote separately as a series, shall be necessary for effecting,
validating or authorizing any one or more of the following:

                (1) the amendment, alteration or repeal of any of the
provisions of the Certificate of Incorporation, as amended, of
the Corporation, or any amendment thereto or any other
certificate filed pursuant to law (including any such
amendment, alteration or repeal effected by any merger or
consolidation to which the Corporation is a party) that would
adversely affect any of the rights, powers or preferences of
outstanding shares of Series C Preferred Stock, provided,
however, that the amendment of the provisions of the
Certificate of Incorporation so as to authorize or create, or the
increase the authorized amount of, any Junior Stock or Pari Passu 
Stockshall not be deemed to affect adversely the voting powers, rights or
preferences of the holders of the Series C Preferred Stock;

                (2) The creation of any shares of any class or series or
any security convertible into shares of any class or series of
capital stock ranking prior to the Series C Preferred Stock in
the distribution of assets on any liquidation, dissolution or
winding-up of the Corporation or in the payment of dividends;
or

                (3) any merger or consolidation with or into, or any
sale, transfer, exchange or lease of all or substantially all of the
assets of the Corporation to, any other corporation, in either
case that would adversely affect any of the rights, powers or
preferences of outstanding shares of Series C Preferred Stock.

                SECTION 4. Redemption.

                (A) The shares of Series C Preferred Stock are
redeemable, at the option of the Corporation, in whole or in
part from time to time, on or after         1998 during the
twelve-month periods beginning on ________ in each of the
following years, at the following redemption prices (expressed
as a percentage of liquidation preference), plus accumulated
and unpaid dividends, whether or not earned or declared, to the
date of redemption (the "Redemption Price"):

Date            Redemption Price

,1998                   .                                         %
,1999                    
,2000
,2001
,2002
,2003
,2004 and thereafter

From and after the date fixed for redemption, dividends on
shares of Series C Preferred Stock called for redemption will
cease to accrue, such shares will no longer be deemed to be
outstanding and all rights in respect of such shares of the
Corporation shall cease, except the right to receive the
Redemption Price, provided that shares of Series C Preferred
Stock may be converted pursuant to Section 6 hereof at any
time prior to the close of business on the date fixed for
redemption of such shares.  If less than all of the outstanding
shares of Series C Preferred Stock are to be redeemed, the
Corporation shall either redeem a portion of the shares held by
each holder or shall select the shares to be redeemed by lot, as
may be determined by the Board of Directors of the
Corporation.

(B) Unless otherwise required by law, notice of redemption
will be sent to the holders of Series C Preferred Stock by first-
class mail, postage prepaid, mailed not less than thirty, nor
more than sixty days prior to the redemption date.  Each such
notice shall state: (i) the redemption date; (ii) the total number
of shares of Series C Preferred Stock to be redeemed and, if
fewer than all the shares held by such holder are to be
redeemed, the number of such shares to be redeemed from
such holder; (iii) the Redemption Price; (iv) the place or places
where certificates for such shares are to be surrendered for
payment of the Redemption Price; (v) that dividends on the
shares to be redeemed will cease to accrue on such redemption
date; and (vi) the conversion rights of the shares to be
redeemed, the period within which conversion rights may be
exercised, and the conversion price of a share of Series C
Preferred Stock on the date such notice is sent.  Upon
surrender of the certificates for any shares so called for
redemption and not previously converted (properly endorsed or
assigned for transfer, if the Board of Directors of the
Corporation shall so require and the notice shall so state), such
shares shall be redeemed by the Corporation on  the date fixed
for redemption and at the Redemption Price set forth in this
Section 4.

SECTION 5.  Liquidation, Dissolution or Winding-Up.

(A) Upon any voluntary or involuntary liquidation, dissolution,
winding-up or termination of the Corporation, the holders of
Series C Preferred Stock at the time outstanding will be
entitled to receive out of the net assets of the Corporation
available for payment to stockholders and subject to the rights
of the holders of any stock of the Corporation ranking senior
to or on a parity with the Series C Preferred Stock in respect
of distributions upon liquidation, dissolution, winding-up or
termination of the Corporation, before any amount shall be
paid or distributed with respect to any Junior Stock liquidating
distributions in the amount of $100 per share plus an amount
equal to all accrued and unpaid dividends thereon (whether or
not earned or declared) to the date fixed for distribution.  If,
upon any liquidation, dissolution, winding up or termination of
the Corporation, the amounts payable with respect to the Series
C Preferred Stock and any Pari Passu Stock are not paid in
full, the holders of the Series C Preferred Stock and such Pari
Passu Stock shall share ratably in any distribution of assets
based on the proportion of their full respective liquidation
preference to the entire amount of unpaid liquidation
preference.  After payment of the full amount to which they
are entitled as provided by the foregoing provisions of this
Section 5(A), the holders of shares  Stock shall not be entitled
to any further right or claim to any of the remaining assets of
the Corporation.

(B) Neither the merger or consolidation of the Corporation
with or into any other corporation, nor the merger or
consolidation of any other corporation with or into the
Corporation, nor the sale, transfer, exchange or lease of all or
any portion of the assets of the Corporation, shall be deemed
to be a dissolution, liquidation or winding-up of the affairs of
the Corporation for purposes of this Section 5.

(C) Written notice of any voluntary or involuntary liquidation,
dissolution or winding-up of the Corporation, stating the
payment date or dates when, and the place or places where, the
amounts distributable to holders of Series C Preferred Stock in
such circumstances shall be payable, shall be given by first-
class mail, postage prepaid, mailed not less than twenty days
prior to any payment date stated therein, to the holders of
Series C Preferred Stock, at the address shown on the books of
the Corporation or the transfer agent for the Series C Preferred
Stock; provided, however, that a failure to give notice as
provided above or any defect therein shall not affect the
Corporation's ability to consummate a voluntary or involuntary
liquidation, dissolution or winding-up of the Corporation.

SECTION 6.  Conversion Rights of Series C Preferred Stock.

(A) The shares of Series C Preferred Stock are convertible at
any time at the option of the holder thereof into shares of
Common Stock at the initial conversion price $_________,
subject to adjustment as provided in Section 7.  For this
purpose, each share of Series C Preferred Stock shall be taken
at $100.00.

(B) Holders of record of Series C Preferred Stock at the close
of business on a dividend payment record date will be entitled
to receive the dividend payable on such shares of Series C
Preferred Stock on the corresponding dividend payment date
notwithstanding the conversion thereof following such dividend
payment record date.  Except as provided in the immediately
preceding sentence, the Corporation will make no payment or
allowance for accumulated and unpaid dividends, whether or
not in arrears, on converted shares of Series C Preferred Stock
or for dividends on the shares of Common Stock issued upon
such conversion.  

(C) No fractional shares of Common Stock will be issued as a
result of conversion, but in lieu thereof, the Corporation shall
pay a cash adjustment in an amount equal to the same fraction
of the Closing Price (as hereinafter defined) on the date on
which the certificate or certificates for such shares were duly
surrendered for conversion, or, if such date is not a Trading
Day (as hereinafter defined), on the next Trading Day.

(D) The shares of Series C Preferred Stock that have been
called for redemption will not be convertible after the close of
business on the second calendar day preceding the date fixed
for redemption, unless the Corporation defaults in making
payment of the amount payable upon such redemption.
  
(E) Any holder of shares of Series C Preferred Stock desiring
to convert such shares into shares of Common Stock shall
surrender the certificate or certificates representing the shares
of Series C Preferred Stock being converted, duly assigned or
endorsed for transfer to the Corporation (or accompanied by
duly executed stock powers relating thereto), at the principal
executive office of the Corporation or the offices of the
transfer agent for the Series C Preferred Stock or such office
or offices in the continental United States of an agent for
conversion as may from time to time be designated by notice
to the holders of the Series C Preferred Stock by the
Corporation or the transfer agent for the Series C Preferred
Stock, accompanied by written notice of conversion, on any
day that is a Business Day in The City of New York.  Such
notice of conversion shall specify (i) the number of shares of
Series C Preferred Stock to be converted and the name or
names in which such holder desires the certificate or
certificates for Common Stock and for any shares of Series C
Preferred Stock not to be so converted to be issued (subject to
compliance with applicable legal requirements if any of such
certificates are to be issued in a name other than the name of
the holder), and (ii) the address to which such holder wishes
delivery to be made of such new certificates to be issued upon
such conversion.

(F) Upon surrender of a certificate representing a share or
shares of Series C Preferred Stock for conversion, the
Corporation shall issue and send by hand delivery (with receipt
to be acknowledged) or by first-class mail, postage prepaid, to
the holder thereof, at the address designated by such holder, a
certificate or certificates representing the number of shares of
Common Stock to which such holder shall be entitled upon
conversion.  In the event that there shall have been surrendered
a certificate or certificates representing shares of Series C
Preferred Stock, only part of which are to be converted, the
Corporation shall issue and deliver to such holder or such
holder's designee in the manner provided in the immediately
preceding sentence a new certificate or certificates representing
the number of shares of Series C Preferred Stock that shall not
have been converted.

(G) The issuance by the Corporation of shares of Common
Stock upon a conversion of shares of Series C Preferred Stock
into shares of Common Stock made at the option of the holder
thereof shall be effective upon the surrender by such holder or
such holder's designee of the certificate or certificates for the
shares of Series C Preferred Stock to be converted, duly
assigned or endorsed for transfer to the Corporation (or
accompanied by duly executed stock powers relating thereto). 
The person or persons entitled to receive the Common Stock
issuable upon such conversion shall be treated for all purposes
as the record holder or holders of such shares of Common
Stock as of the close of business on the effective date of the
conversion.  No allowance or adjustment shall be made in
respect of dividends payable to holders of Common Stock of
record as of any date prior to such effective date.

(H) Whenever the Corporation shall issue shares of Common
Stock upon conversion of shares of Series C Preferred Stock as
contemplated by this Section 6, the Corporation shall issue,
together with each such share of Common Stock, one right to
purchase Series A Junior Participating Preferred Stock of the
Corporation (or other securities in lieu thereof) pursuant to the
Amended Rights Agreement, dated as of October 4, 1989 (the
"Rights Agreement"), between the Corporation and Harris
Trust and Savings Bank, as Rights Agent, as such Rights
Agreement may from time to time be amended, or any similar
rights issued to holders of Common Stock of the Corporation
in addition thereto or in replacement therefor (such rights,
together with any additional or replacement rights, being
collectively referred to as the "Rights"), whether or not such
Rights shall be exercisable at such time, but only if such
Rights are issued and outstanding and held by other holders of
Common Stock of the Corporation (or are evidenced by
outstanding share certificates representing Common Stock) at
such time and have not expired or been redeemed.

(I) The Corporation shall at all times reserve and keep
available out of its authorized and unissued Common Stock,
solely for issuance upon the conversion of shares of Series C
Preferred Stock as herein provided, free from any preemptive
or other similar rights, such number of shares of Common
Stock as shall from time to time be issuable upon the
conversion of all the shares of Series C Preferred Stock then
outstanding.  Notwithstanding the foregoing, the Corporation
shall be entitled to deliver upon conversion of shares of Series
C Preferred Stock, as herein provided, shares of Common
Stock reacquired and held in the treasury of the Corporation
(in lieu of the issuance of authorized and unissued shares of
Common Stock), so long as any such treasury shares are free
and clear of all liens, charges, security interests or
encumbrances.  All shares of Common Stock delivered upon
conversion of the Series C Preferred Stock shall be duly
authorized, validly issued, fully paid and non-assessable, free
and clear of all liens, claims, security interests and other
encumbrances.  The Corporation shall prepare and shall use its
best efforts to obtain and keep in force such governmental or
regulatory permits or other authorizations as may be required
by law, and shall comply with all applicable requirements as to
registration or qualification of the Common Stock (and all
requirements to list the Common Stock issuable upon
conversion of Class C Preferred Stock that are at the time
applicable), in order to enable the Corporation lawfully to issue
and deliver to each holder of record of Series C Preferred
Stock such number of shares of its Common Stock as shall
from time to time be sufficient to effect the conversion of all
shares of Series C Preferred Stock then outstanding and
convertible into shares of Common Stock.

SECTION 7.  Adjustment of Conversion Price.

(A) Adjustment of Conversion Price.  The conversion price at
which a share of Series C Preferred Stock is convertible into
Common Stock shall be subject to adjustment from time to
time as follows:

(i) In case the Corporation shall pay or make a dividend or
other distribution on any class or series of capital stock of the
Corporation exclusively in Common Stock, the conversion
price in effect at the opening of business on the day following
the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution shall be reduced by
multiplying such conversion price by a fraction of which the
numerator shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such
determination and the denominator shall be the sum of such
number of shares and the total number of shares constituting
such dividend or other distribution or exchange, such reduction
to become effective immediately after the opening of business
on the day following the date fixed for such determination. 
For the purposes of this subparagraph (i), the number of shares
of Common Stock at any time outstanding shall not include
shares held in the treasury of the Corporation.  The Corpo-
ration shall not pay any dividend or make any distribution on
shares of any class or series of capital stock of the Corporation
exclusively in Common Stock held in the treasury of the
Corporation.

(ii) In case the Corporation shall pay or make a dividend or
other distribution on its Common Stock consisting exclusively
of, or shall otherwise issue to all holders of its Common Stock,
rights or warrants entitling the holders thereof to subscribe for
or purchase shares of Common Stock at a price per share less
than the current market price per share (determined as provided
in subparagraph (vii) of this Section 7(A)) of the Common
Stock on the date fixed for the determination of stockholders
entitled to receive such rights or warrants, the conversion price
in effect at the opening of business on the day following the
date fixed for such determination shall be reduced by multi-
plying such conversion price by a fraction of which the
numerator shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such
determination plus the number of shares of Common Stock
which the aggregate of the offering price of the total number
of shares of Common Stock so offered for subscription or
purchase would purchase at such current market price and the
denominator shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such
determination plus the number of shares of Common Stock so
offered for subscription or purchase, such reduction to become
effective immediately after the opening of business on the day
following the date fixed for such determination.  For the
purposes of this subparagraph (ii), the number of shares of
Common Stock at any time outstanding shall not include
shares held in the treasury of the Corporation.  The
Corporation shall not issue any rights or warrants in respect of
shares of Common Stock held in the treasury of the
Corporation.  In case any rights or warrants referred to in this
subparagraph (ii) in respect of which an adjustment shall have
been made shall expire unexercised within 45 days after the
same shall have been distributed or issued by the Corporation,
the conversion price shall be readjusted at the time of such
expiration to the conversion price that would have been in
effect if no adjustment had been made on account of the
distribution or issuance of such expired rights or warrants.

(iii) In case outstanding shares of Common Stock shall be
subdivided into a greater number of shares of Common Stock,
the conversion price in effect at the opening of business on the
day following the day upon which such subdivision becomes
effective shall be proportionately reduced, and conversely, in
case outstanding shares of Common Stock shall each be
combined into a smaller number of shares of Common Stock,
the conversion price in effect at the opening of business on the
day following the day upon which such combination becomes
effective shall be proportionately increased, such reduction or
increase, as the case may be, to become effective immediately
after the opening of business on the day following the day
upon which such subdivision or combination becomes
effective.

(iv) Subject to the last sentence of this subparagraph (iv), in
case the Corporation shall, by dividend or otherwise, distribute
to all holders of its Common Stock evidences of its
indebtedness, shares of any class or series of capital stock,
cash or assets (including securities, but excluding any rights or
warrants referred to in subparagraph (ii) of this Section 7(A),
any dividend or distribution paid exclusively in cash and any
dividend or distribution referred to in subparagraph (i) of this
Section 7(A)), the conversion price shall be reduced so that the
same shall equal the price determined by multiplying the
conversion price in effect immediately prior to the
effectiveness of the conversion price reduction contemplated by
this subparagraph (iv) by a fraction of which the numerator
shall be the current market price per share (determined as
provided in subparagraph (vii) of this Section 7(A)) of the
Common Stock on the date fixed for the payment of such
distribution (the "Reference Date") less the fair market value
(as determined in good faith by the Board of Directors, whose
determination shall be conclusive and described in a resolution
of the Board of Directors), on the Reference Date, of the
portion of the evidences of indebtedness, shares of capital
stock, cash and assets so distributed applicable to one share of
Common Stock and the denominator shall be such current
market price per share of the Common Stock, such reduction to
become effective immediately prior to the opening of business
on the day following the Reference Date.  If the Board of
Directors determines the fair market value of any distribution
for purposes of this subparagraph (iv) by reference to the
actual or when issued trading market for any securities
comprising such distribution, it must in doing so consider the
prices in such market over the same period used in computing
the current market price per share of Common Stock pursuant
to subparagraph (vii) of this Section 7(A).  For purposes of
this subparagraph (iv), any dividend or distribution that
includes shares of Common Stock or rights or warrants to
subscribe for or purchase shares of Common Stock shall be
deemed instead to be (1) a dividend or distribution of the
evidences of indebtedness, shares of capital stock, cash or
assets other than such shares of Common Stock or such rights
or warrants (making any conversion price reduction required
by this subparagraph (iv)) immediately followed by (2) a
dividend or distribution of such shares of Common Stock or
such rights or warrants (making any further conversion price
reduction required by subparagraph (i) or (ii) of this Section
7(A), except (A) the Reference Date of such dividend or distri-
bution as defined in this subparagraph (iv) shall be substituted
as "the date fixed for the determination of stockholders entitled
to receive such dividend or other distribution," "the date fixed
for the determination of stockholders entitled to receive such
rights or warrants" and "the date fixed for such determination"
within the meaning of subparagraphs (i) and (ii) of this Section
7(A) and (B) any shares of Common Stock included in such
dividend or distribution shall not be deemed "outstanding at the
close of business on the date fixed for such determination"
within the meaning of subparagraph (i) of this Section 7(A).

(v) In case the Corporation shall pay or make a dividend or
other distribution on its Common Stock exclusively in cash
(excluding, in the case of any regular cash dividend on the
Common Stock, the portion thereof that does not exceed the
per share amount of the next preceding regular cash dividend
on the Common Stock (as adjusted to appropriately reflect any
of the events referred to in subparagraphs (i), (ii), (iii), (iv), (v)
and (vi) of this Section 7(A), or all of such regular cash
dividend if the annualized amount thereof per share of
Common Stock does not exceed 15% of the current market
price per share (determined as provided in subparagraph (vii)
of this Section 7(A)) of the Common Stock on the Trading
Day (as defined in Section 7(E)) next preceding the date of
declaration of such dividend), the conversion price shall be
reduced so that the same shall equal the price determined by
multiplying the conversion price in effect immediately prior to
the effectiveness of the conversion price reduction
contemplated by this subparagraph (v) by a fraction of which
the numerator shall be the current market price per share
(determined as provided in subparagraph (vii) of this Section
7(A)) of the Common Stock on the date fixed for the payment
of such distribution less the amount of cash so distributed and
not excluded as provided above applicable to one share of
Common Stock and the denominator shall be such current
market price per share of the Common Stock, such reduction to
become effective immediately prior to the opening of business
on the day following the date fixed for the payment of such
distribution.

(vi) In case a tender or exchange offer made by the
Corporation or any subsidiary of the Corporation for all or any
portion of the Corporation's Common Stock shall expire and
such tender or exchange offer shall involve the payment by the
Corporation or such subsidiary of consideration per share of
Common Stock having a fair market value (as determined in
good faith by the Board of Directors, whose determination
shall be conclusive and described in a resolution of the Board
of Directors) at the last time (the "Expiration Time") tenders or
exchanges may be made pursuant to such tender or exchange
offer (as it shall have been amended) that exceeds 10% of the
current market price per share (determined as provided in
subparagraph (vii) of this Section 7(A)) of the Common Stock
on the Trading Day next succeeding the Expiration Time, the
conversion price shall be reduced so that the same shall equal
the price determined by multiplying the conversion price in
effect immediately prior to the effectiveness of the conversion
price reduction contemplated by this subparagraph (vi) by a
fraction of which the numerator shall be the number of shares
of Common Stock outstanding (including any tendered or
exchanged shares) at the Expiration Time multiplied by the
current market price per share (determined as provided in
subparagraph (vii) of this Section 7(A)) of the Common Stock
on the Trading Day next succeeding the Expiration Time and
the denominator shall be the sum of (x) the fair market value
(determined as aforesaid) of the aggregate consideration
payable to stockholders based on the acceptance (up to any
maximum specified in the terms of the tender or exchange
offer) of all shares validly tendered or exchanged and not
withdrawn as of the Expiration Time (the shares deemed so
accepted, up to any such maximum, being referred to as the
"Purchased Shares") and (y) the product of the number of
shares of Common Stock outstanding (less any Purchased
Shares) at the Expiration Time and the current market price per
share (determined as provided in subparagraph (vii) of this
Section 7(A)) of the Common Stock on the Trading Day next
succeeding the Expiration Time, such reduction to become
effective immediately prior to the opening of business on the
day following the Expiration Time.  Notwithstanding anything
contained in this Section 7(A)(vi) to the contrary, no
adjustment shall be made to the conversion price in the case of
a tender offer that complies with Rule 13e-4(h)(v) under the
Exchange Act, or any successor rule thereto.

(vii) For the purpose of any computation under subparagraphs
(ii), (iv), (v) and (vi) of this Section 7(A), the current market
price per share of Common Stock on any date in question shall
be deemed to be the average of the daily Closing Prices (as
defined in Section 7(E)) for the five consecutive Trading Days
selected by the Company commencing not more than 20
Trading Days before, and ending not later than, the earlier of
the day in question and, if applicable, the day before the "ex"
date with respect to the issuance or distribution requiring such
computation; provided, however, that in each event another
event occurs that would require an adjustment pursuant to
subparagraph (i) through (vi), inclusive, the Board of Directors
may make such adjustments to the Closing Prices during such
five Trading Day period as it deems appropriate to effectuate
the intent of the adjustments in this Section 7(A), any such
determination by the Board of Directors shall be set forth in a
Board Resolution and shall be conclusive.  For purposes of this
paragraph, the term "ex" date, (1) when used with respect to
any issuance or distribution, means the first date on which the
Common Stock trades regular way on the relevant exchange or
in the relevant market from which the Closing Price was
obtained without the right to receive such issuance or
distribution, and (2) when used with respect to any tender or
exchange offer means the first date on which the Common
Stock trades regular way on such exchange or in such market
after the Expiration Time of such offer.

(viii) The Corporation may make such reductions in the
conversion price, in addition to those required by
subparagraphs (i), (ii), (iii), (iv), (v) and (vi) of this Section
7(A), as it considers to be advisable to avoid or diminish any
income tax to holders of Common Stock or rights to purchase
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.  The Corporation from time to
time may reduce the conversion price by any amount for any
period of time if the period is at least twenty days, the
reduction is irrevocable during the period, and the Board of
Directors of the Corporation shall have made a determination
that such reduction would be in the best interest of the
Corporation, which determination shall be conclusive. 
Whenever the conversion price is reduced pursuant to the
preceding sentence, the Corporation shall mail to holders of
record of the Series C Preferred Stock a notice of the reduction
at least fifteen days prior to the date the reduced conversion
price takes effect, and such notice shall state the reduced
conversion price and the period it will be in effect.

(ix) No adjustment in the conversion price shall be required
unless such adjustment would require an increase or decrease
of at least 1% in the conversion price; provided, however, that
any adjustments which by reason of this subparagraph (ix) are
not required to be made shall be carried forward and taken into
account in any subsequent adjustment.

(x) Whenever the conversion price is adjusted as herein
provided:

(1) the Corporation shall compute the adjusted conversion price
and shall prepare a certificate signed by the Treasurer of the
Corporation setting forth the adjusted conversion price and
showing in reasonable detail the facts upon which such
adjustment is based, and such certificate shall forthwith be
filed with the transfer agent for the Series C Preferred Stock;
and

(2) a notice stating the conversion price has been adjusted and
setting forth the adjusted conversion price shall forthwith be
required, and as soon as practicable after it is required such
notice shall be mailed by the Corporation to all record holders
of shares of Series C Preferred Stock at their last addresses as
they shall appear upon the stock transfer books of the
Corporation.

(B) Reclassification, Consolidation, Merger or Sale of Assets. 
In the event that the Corporation shall be a party to any
transaction (including without limitation any recapitalization or
reclassification of the Common Stock (other than a change in
par value, or from par value to no par value, or from no par
value to par value, or as a result of a subdivision or
combination of the Common Stock), any consolidation of the
Corporation with, or merger of the Corporation into, any other
person, any merger of another person into the Corporation
(other than a merger which does not result in a reclassification,
conversion, exchange or cancellation of outstanding shares of
Common Stock of the Corporation), any sale or transfer of all
or substantially all of the assets of the Corporation or any
compulsory share exchange) pursuant to which the Common
Stock is converted into the right to receive other securities,
cash or other property), then lawful provisions shall be made
as part of the terms of such transaction whereby the holder of
each share of Series C Preferred Stock then outstanding shall
have the right thereafter, to convert such share only into (i) in
the case of any such transaction other than a Common Stock
Fundamental Change (as defined in Section 7(E)), the kind and
amount of securities, cash and other property receivable upon
such transaction by a holder of the number of shares of
Common Stock of the Corporation into which such share of
Series C Preferred Stock could have been converted
immediately prior to such transaction, after giving effect, in the
case of any Non-Stock Fundamental Change, to any adjustment
in the conversion price required by the provisions of Section
7(D), and (ii) in the case of a Common Stock Fundamental
Change, common stock of the kind received by holders of
Common Stock as a result of such Common Stock
Fundamental Change in an amount determined pursuant to the
provisions of Section 7(D).  The Corporation or the person
formed by such consolidation or resulting from such merger or
which acquires such assets or which acquires the Corporation's
shares, as the case may be, shall make provisions in its
certificate or articles of incorporation or other constituent
document to establish such right.  Such certificate or articles of
incorporation or other constituent document shall provide for
adjustments which, for events subsequent to the effective date
of such certificate or articles of incorporation or other
constituent document, shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 7. 
The above provisions shall similarly apply to successive
transactions of the foregoing type.

(C) Prior Notice of Certain Events.  In case:

(i) the Corporation shall (1) declare any dividend (or any other
distribution) on its Common Stock, other than (A) a dividend
payable in shares of Common Stock or (B) a dividend that
would not require an adjustment pursuant to Section 7(A)(iv)
or (v) or (2) authorize a tender or exchange offer that would
require an adjustment pursuant to Section 7(A)(vi); or

(ii) the Corporation shall authorize the granting to all holders
of Common Stock of rights or warrants to subscribe for or
purchase any shares of stock of any class or series or of any
other rights or warrants; or

(iii) of any reclassification of Common Stock (other than a
subdivision or combination of the outstanding Common Stock,
or a change in par value, or from par value to no par value, or
from no par value to par value), or of any consolidation or
merger to which the Corporation is a party and for which
approval of any stockholders of the Corporation shall be
required, or of the sale or transfer of all or substantially all of
the assets of the Corporation or of any compulsory share
exchange whereby the Common Stock is converted into other
securities, cash or other property; or

(iv) of the voluntary or involuntary dissolution, liquidation or
winding up of the Corporation;

then the Corporation shall cause to be filed with the transfer
agent for the Series C Preferred Stock, and shall cause to be
mailed to the holders of record of the Series C Preferred Stock,
at their last addresses as they shall appear upon the stock
transfer books of the Corporation, at least fifteen days prior to
the applicable record or effective date hereinafter specified, a
notice stating (x) the date on which a record (if any) is to be
taken for the purpose of such dividend, distribution,
redemption, repurchase, rights or warrants or, if a record is not
to be taken, the date as of which the holders of Common Stock
of record to be entitled to such dividend, distribution,
redemption, repurchase, rights or warrants are to be determined
or (y) the date on which such reclassification, consolidation,
merger, sale, transfer, share exchange, dissolution, liquidation
or winding up is expected to become effective, and the date as
of which it is expected that holders of Common Stock of
record shall be entitled to exchange their shares of Common
Stock for securities, cash or other property deliverable upon
such reclassification, consolidation, merger, sale, transfer, share
exchange, dissolution, liquidation or winding up (but no failure
to mail such notice or any defect therein or in the mailing
thereof shall affect the validity of the corporate action required
to be specified in such notice).

(D) Adjustments in Case of Fundamental Changes. 
Notwithstanding any other provision in this Section 7 to the
contrary, if any Fundamental Change (as defined in Section
7(E)) occurs, then the conversion price in effect will be
adjusted immediately after such Fundamental Change as
described below.  In addition, in the event of a Common Stock
Fundamental Change (as defined in Section 7(E)), each share
of Series C Preferred Stock shall be convertible solely into
common stock of the kind and amount received by holders of
Common Stock as the result of such Common Stock
Fundamental Change as more specifically provided in the
following clauses (D)(i) and (D)(ii). 

For purposes of calculating any adjustment to be made
pursuant to this Section 7(D) in the event of a Fundamental
Change, immediately after such Fundamental Change: 

(i) in the case of a Non-Stock Fundamental Change (as defined
in Section 7(E)), the conversion price of the Series C Preferred
Stock shall 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 effected pursuant to this Section 7, and (B) the
result obtained by multiplying the greater of the Applicable
Price (as defined in Section 7(E)) or the then applicable
Reference Market Price (as defined in Section 7(E)) by a
fraction of which the numerator shall be $50.00 and the
denominator shall be (x) the then-current Redemption Price per
share of Series C Preferred Stock or (y) for any Non-Stock
Fundamental Change that occurs before the Series C Preferred
Stock becomes redeemable by the Corporation pursuant to
Section 4, the applicable price per share set forth for the date
of such Non-Stock Fundamental Change in the following table:


Date of Non-Stock Fundamental Change               Price 

After date of original issuance of Series C Preferred Stock and 
     on or before _______, 1995

After _____ __, 1995, and on or before _____ __, 1996

After _____ __, 1996, and on or before _____ __, 1997

After _____ __, 1997, and on or before _____ __, 1998


plus, in any case referred to in this clause (y), an amount equal
to all dividends on the Series C Preferred Stock accrued and
unpaid thereon, whether or not earned or declared, to but
excluding the date of such Non-Stock Fundamental Change;
and 

(ii) in the case of a Common Stock Fundamental Change, the
conversion price of the Series C Preferred Stock in effect
immediately prior to such Common Stock Fundamental
Change, but after giving effect to any other prior adjustments
effected pursuant to this Section 7, shall thereupon be adjusted
by multiplying such conversion price by a fraction of which
the numerator shall be the Purchaser Stock Price (as defined in
Section 7(E)) and the denominator shall be the Applicable
Price; provided, however, that in the event of a Common Stock
Fundamental Change in which (A) 100% by value of the
consideration received by a holder of Common Stock is
common stock of the successor, acquiror or other third party
(and cash, if any, is paid with respect to any fractional interests
in such common stock resulting from such Common Stock
Fundamental Change) and (B) all of the Common Stock shall
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 Series C Preferred Stock in effect immediately
prior to such Common Stock Fundamental Change shall
thereupon be adjusted by multiplying such conversion price by
a fraction of which the numerator shall be one (1) and the
denominator shall be the number of shares of common stock of
the successor, acquiror, or other third party received by a
stockholder for one share of Common Stock as a result of such
Common Stock Fundamental Change.

(E) Definitions.  The following definitions shall apply to terms
used in this Section 7:

(1) "Applicable Price" shall mean (i) in the event of a
Non-Stock Fundamental Change in which the holders of the
Common Stock receive only cash, the amount of cash received
by a stockholder for one share of Common Stock and (ii) in
the event of any other Non-Stock Fundamental Change or any
Common Stock Fundamental Change, the average of the daily
Closing Prices of the Common Stock for the ten consecutive
Trading Days prior to and including the record date for the
determination of the holders of Common Stock entitled to
receive 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 Common Stock shall have
the right to receive such securities, cash or other property, in
each case, as adjusted in good faith by the Board of Directors
of the Corporation to appropriately reflect any of the events
referred to in subparagraphs (i), (ii), (iii), (iv), (v) and (vi) of
Section 7(A).

(2) "Closing Price" of any common stock on any day shall
mean the last reported sale price regular way on such day or,
in case no such sale takes place on such day, the average of
the reported closing bid and asked prices regular way of the
common stock in each case on the principal national securities
exchange on which the Common Stock is traded, or if the
Common Stock is not listed or traded on any national
securities exchange, on the National Market System of the
National Association of Securities Dealers, Inc., or, if the
common stock is not quoted or admitted to trading on such
quotation system, on the quotation system on which the
common stock is listed or admitted to trading or quoted, or, if
not listed or admitted to trading or quoted on any national
securities exchange or quotation system, the average of the
closing bid and asked prices of the common stock in the over-
the-counter market on the day in question as reported by the
National Quotation Bureau Incorporated, or a similarly
generally accepted reporting service, or, if not so available in
such manner, as furnished by any New York Stock Exchange
member firm selected from time to time by the Board of
Directors of the Corporation for that purpose or, if not so
available in such manner, as otherwise determined in good
faith by the Board of Directors.

(3) "Common Stock Fundamental Change" shall mean any
Fundamental Change in which more than 50% by value (as
determined in good faith by the Board of Directors of the
Corporation) of the consideration received by holders of
Common Stock consists of common stock that for each of the
ten consecutive Trading Days referred to with respect to such
Fundamental Change in Section 7(E)(1) above 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) the Corporation continues to exist after the
occurrence of such Fundamental Change and the outstanding
shares of Series C Preferred Stock continue to exist as
outstanding shares of Series C Preferred Stock, or (ii) not later
than the occurrence of such Fundamental Change, the
outstanding shares of Series C Preferred Stock are converted
into or exchanged for shares of convertible preferred stock of a
corporation succeeding to the business of the Corporation,
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 Series C Preferred Stock.

(4) "Fundamental Change" shall mean the occurrence of any
transaction or event in connection with a plan pursuant to
which all or substantially all of the 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, however, 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 Common Stock of the Corporation 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 of consideration per share which a holder of Common
Stock could have received in such transactions or events as a
result of which more than 50% of the Common Stock of the
Corporation shall have been exchanged for, converted into, or
acquired for or constitute solely the right to receive securities,
cash or other property.

(5) "Non-Stock Fundamental Change" shall mean any
Fundamental Change other than a Common Stock Fundamental
Change.

(6) "Purchaser Stock Price" shall mean, with respect to any
Common Stock Fundamental Change, the average of the daily
Closing Prices of the common stock received in such Common
Stock Fundamental Change for the ten consecutive Trading
Days prior to and including the record date for the
determination of the holders of Common Stock entitled to
receive such common stock, or, if there is no such record date,
the date upon which the holders of the Common Stock shall
have the right to receive such common stock, in each case, as
adjusted in good faith by the Board of Directors of the Cor-
poration to appropriately reflect any of the events referred to in
subparagraphs (i), (ii), (iii), (iv), (v) and (vi) of Section 7(A);

(7) "Reference Market Price" shall initially mean $_____ and
in the event of any adjustment to the conversion price other
than as a result of a Non-Stock Fundamental Change, the
Reference Market Price shall also be adjusted so that the ratio
of the Reference Market Price to the conversion price after
giving effect to any such adjustment shall always be the same
as the ratio of $_____ to the initial conversion price per share.

(8) "Trading Day" shall mean a day on which securities are
traded on the national securities exchange or quotation system
or in the over-the-counter market used to determine the
Closing Price.

(F) Dividend or Interest Reinvestment Plans.  Notwithstanding
the foregoing provisions, the issuance of any shares of
Common Stock pursuant to any present or future plan
providing for the reinvestment of dividends or interest payable
on securities of the Corporation and the investment of addi-
tional optional amounts in shares of Common Stock under any
such plan, and the issuance of any shares of Common Stock or
options or rights to purchase such shares pursuant to any
present or future employee benefit plan or program of the
Corporation or pursuant to any option, warrant, right or
exercisable, exchangeable or convertible security outstanding as
of the date the Series C Preferred Stock is first issued, shall
not be deemed to constitute an issuance of Common Stock or
exercisable, exchangeable or convertible securities by the
Corporation to which any of the adjustment provisions
described above applies.  There shall also be no adjustment of
the conversion price in case of the issuance of any stock (or
securities convertible into or exchangeable for stock) of the
Corporation except as specifically described in this Section 7. 
If any action would require adjustment of the conversion price
pursuant to more than one of the provisions described above,
only one adjustment shall be made and such adjustment shall
be the amount of adjustment which has the highest absolute
value to holders of Series C Preferred Stock.

(G) Certain Additional Rights.  In case the Corporation shall,
by dividend or otherwise, declare or make a distribution on its
Common Stock referred to in Section 7(A)(iv) or 7(A)(v)
(including, without limitation, dividends or distributions
referred to in the last sentence of Section 7(A)(iv)), the holder
of each share of Series C Preferred Stock, upon the conversion
thereof subsequent to the close of business on the date fixed
for the determination of stockholders entitled to receive such
distribution and prior to the effectiveness of the conversion
price adjustment in respect of such distribution, shall also be
entitled to receive for each share of Common Stock into which
such share of Series C Preferred Stock is converted, the portion
of the shares of Common Stock, rights, warrants, evidences of
indebtedness, shares of capital stock, cash and assets so
distributed applicable to one share of Common Stock;
provided, however, that, at the election of the Corporation
(whose election shall be evidenced by a resolution of the
Board of Directors) with respect to all holders so converting,
the Corporation may, in lieu of distributing to such holder any
portion of such distribution not consisting of cash or securities
of the Corporation, pay such holder an amount in cash equal to
the fair market value thereof (as determined in good faith by
the Board of Directors, whose determination shall be
conclusive and described in a resolution of the Board of
Directors).  If any conversion of a share of Series C Preferred
Stock described in the immediately preceding sentence occurs
prior to the payment date for a distribution to holders of
Common Stock which the holder of the share of Series C
Preferred Stock so converted is entitled to receive in
accordance with the immediately preceding sentence, the
Corporation may elect (such election to be evidenced by a
resolution of the Board of Directors) to distribute to such
holder a due bill for the shares of Common Stock, rights,
warrants, evidences of indebtedness, shares of capital stock,
cash or assets to which such holder is so entitled, provided that
such due bill (i) meets any applicable requirements of the
principal national securities exchange or other market on which
the Common Stock is then traded and (ii) requires payment or
delivery of such shares of Common Stock, rights, warrants,
evidences of indebtedness, shares of capital stock, cash or
assets no later than the date of payment or delivery thereof to
holders of shares of Common Stock receiving such distribution.

SECTION 8.  Ranking; Attributable Capital and Adequacy of
Surplus; Retirement of Shares.

(A) The Series C Preferred Stock shall rank senior to all shares
of Junior Stock and pari passu with the Pari Passu Stock of
the Corporation as to the payment of dividends and amounts
upon the liquidation, dissolution or winding-up of the
Corporation.  The ranking of any subsequent series of
Preferred Stock, par value $100 per share, issued by the
Corporation as compared to the Series C Preferred Stock as to
the payment of dividends and amounts upon the liquidation,
dissolution or winding-up of the Corporation shall be as
specified in the Certificate of Incorporation, as amended, of the
Corporation and, if appropriate, shall also be subject to the
provisions of paragraph (B) of Section 2 hereof.

(B) The capital of the Corporation allocable to the Series C
Preferred Stock for purposes of the New York Business
Corporation Law (the "BCL") shall be $100 per share.

(C) Any shares of Series C Preferred Stock acquired by the
Corporation by reason of the conversion or redemption of such
shares, or otherwise so acquired, shall be retired as shares of
Series C Preferred stock and restored to the status of
authorized but unissued shares of Preferred Stock, par value
$100 per share, of the Corporation, undesignated as to series,
and may thereafter be reissued as part of a new series of such
Preferred Stock as permitted by law.

SECTION 9.  Miscellaneous.

(A) All notices referred to herein shall be in writing, and all
notices hereunder shall be deemed to have been given upon the
earlier of receipt thereof or three business days after the
mailing thereof if sent by registered or certified mail (unless
first-class mail shall be specifically permitted for such notice
under the terms of this paragraph 4C) with postage prepaid
addressed:  (i) if to the Corporation, to its office at Corning,
New York 14831 (Attention:  the Secretary) or to the transfer
agent for the Series C Preferred Stock, or other agent of the
Corporation designated as permitted by this paragraph 4C, or
(ii) if to any holder of the Series C Preferred Stock or
Common Stock, as the case may be, to such holder at the
address of such holder as listed in the stock record books of
the Corporation (which may include the records of any transfer
agent for the Series C Preferred Stock or Common Stock, as
the case may be) or (iii) to such other address as the
Corporation or any such holder, as the case may be, shall have
designated by notice similarly given.

(B) The term "Common Stock" as used in this paragraph 4C
means the Corporation's Common Stock, par value $0.50 per
share, as the same exists at the date of filing of a Certificate of
Amendment to the Certificate of Incorporation of the
Corporation relating to the Series C Preferred Stock or any
other class of stock resulting from successive changes or
reclassifications of such Common Stock consisting solely of
changes in par value, or from par value to no par value, or
from no par value to par value.  However, subject to the
provisions of Section 7(B), shares of Common Stock issuable
on conversion of shares of Series C Preferred Stock shall
include only shares of the class designated as Common Stock
of the Corporation at the date of the filing of this instrument
with the State of New York or shares of any class or classes
resulting from any reclassification or reclassifications thereof
and which have no preference in respect of dividends or of
amounts payable in the event of any voluntary or involuntary
liquidation, dissolution or winding-up of the Corporation and
which are not subject to redemption by the Corporation;
provided that if at any time there shall be more than one such
resulting class, the shares of each such class then so issuable
shall be substantially in the proportion which the total number
of shares of such class resulting from all such reclassifications
bears to the total number of shares of such classes resulting
from all such reclassifications.

(C) The Corporation shall pay any and all stock transfer and
documentary stamp taxes that may be payable in respect of any
issuance or delivery of shares of Series C Preferred Stock or
shares of Common Stock or other securities issued on account
of Series C Preferred Stock pursuant hereto or certificates
representing such shares or securities.  The Corporation shall
not, however, be required to pay any such tax that may be
payable in respect of any transfer involved in the issuance or
delivery of shares of Series C Preferred Stock or Common
Stock or other securities in a name other than that in which the
shares of Series C Preferred Stock with respect to which such
shares or other securities are issued or delivered were
registered, or in respect of any payment to any person with
respect to any such shares or securities other than a payment to
the registered holder thereof, and shall not be required to make
any such issuance, delivery or payment unless and until the
person otherwise entitled to such issuance, delivery or payment
has paid to the Corporation the amount of any such tax or has
established, to the satisfaction of the Corporation, that such tax
has been paid or is not payable.

(D) In the event that a holder of shares of Series C Preferred
Stock shall not by written notice designate the name in which
shares of Common Stock to be issued upon conversion of such
shares should be registered or to whom payment upon
redemption of shares of Series C Preferred Stock should be
made or the address to which the certificate or certificates
representing such shares, or such payment, should be sent, the
Corporation shall be entitled to register such shares, and make
such payment, in the name of the holder of such Series C
Preferred Stock as shown on the records of the Corporation
and to send the certificate or certificates representing such
shares, or such payment, to the address of such holder shown
on the records of the Corporation.

(E) The Corporation may appoint, and from time to time
discharge and change, a transfer agent for the Series C
Preferred Stock.  Upon any such appointment or discharge of a
transfer agent, the Corporation shall send notice thereof by
first-class mail, postage prepaid, to each holder of record of
Series C Preferred Stock.

FOURTH:  This amendment of the Certificate of Incorporation
was authorized by resolutions duly adopted by the Board of
Directors of the Corporation at a meeting thereof duly called
and held on                    , 1994, and by the Executive
Committee of the Board of Directors of the Corporation, acting
pursuant to delegated authority, at a meeting thereof duly called and held 
on               , 1994at which, in each case, a quorum was present and

"Agent").  Unless otherwise defined herein, all capitalized 
terms used herein shall have the meanings ascribed to 
them in the Amended and Restated Limited Partnership 
Agreement of Corning Delaware, dated as of _______, 1994 
(the "Limited Partnership Agreement").  

WHEREAS, Corning Delaware may pursuant to the Underwriting

WHEREAS, Corning is guaranteeing the payment of Dividends 
on the Preferred Securities, and payment of the Redemption 
Price and payments on liquidation with respect to the 
Preferred Securities to the extent provided in the
Guarantee;

WHEREAS, Corning wishes to sell to Corning
Delaware, and Corning Delaware wishes to purchase from
Corning, Subordinated Debentures (as defined below) in an
aggregate principal amount equal to the sum of the capital
contributed by Corning to Corning Delaware (the "General
Partner Contribution") and the aggregate stated liquidation
preference of the Preferred Securities issued and sold by
Corning Delaware pursuant to the Underwriting Agreement
less $                       , which is equal to 1% of such sum; and

WHEREAS, Corning has duly authorized the creation of an 
issue of its Subordinated Debentures of substantially 
the tenor and amount hereinafter set forth, and to
provide therefor, Corning has duly authorized the execution
and delivery of this Fiscal Agency Agreement; and

WHEREAS, all things necessary to make the Subordinated 
Debentures, when executed by Corning and authenticated 
and delivered hereunder and duly issued by Corning, the 
valid obligations of Corning, and to make this
Fiscal Agency Agreement a valid agreement of Corning, in
accordance with their and its terms, have been done.
              
NOW, THEREFORE, in consideration of the agreements and 
obligations set forth herein and for other good
and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, Corning, Corning Delaware
and the Agent hereby agree as follows:


Article I
The Subordinated Debentures
                             
1.1  The Subordinated Debentures.  Subject to
the terms and conditions herein, on the first Closing Date, 
Corning agrees to issue and sell to Corning Delaware, and
Corning Delaware agrees to purchase from Corning,
$___________ aggregate principal amount of __ % Convertible
Subordinated Debentures of Corning (the "Subordinated
Debentures") for an amount payable by check in next day
funds equal to the principal amount of such Subordinated
Debentures.  After the first Closing Date, subject to the terms
and conditions of this Agreement, Corning agrees to issue and
sell to Corning Delaware, and Corning Delaware agrees to
purchase, an aggregate principal amount of Subordinated
Debentures equal to the difference between (i) the sum of the
total capital contributions paid to the Partnership by  Corning
after the first Closing Date plus the aggregate stated liquidation
preference of Preferred Securities sold by Corning Delaware
after such date pursuant to the Underwriting Agreement and
(iii) the product of the amount determined in accordance with
clause (i) and 1%, for an amount payable by check in next day
funds equal to such aggregate principal amount of such
Subordinated Debentures.  

1.2 Authentication.  The Agent shall, upon delivery 
of Subordinated Debentures to it by Corning, duly
executed on behalf of Corning, and a written order or orders to
authenticate and deliver Subordinated Debentures in a stated
amount, (i) authenticate and register not more than said
aggregate principal amount of Subordinated Debentures and
deliver them in accordance with the written order or orders of
Corning and (ii) thereafter authenticate and register
Subordinated Debentures and deliver them in accordance with
the provisions of this Agreement.

1.3  Form.  The Subordinated Debentures shall
be issued in fully registered form without coupons, shall be in
denominations of U.S. $1,000 and integral multiples thereof or
such other amount as the holder of the Subordinated
Debentures shall request and shall be dated the date of
authentication thereof and shall bear interest from the date
specified therein.  The Subordinated Debentures will be in
substantially the form set forth in Exhibit 1 hereto.  The
Subordinated Debentures shall be executed on behalf of
Corning by the signature, manual or in facsimile, of its duly
authorized representative.  In the event that any representative
of Corning who shall have executed or whose facsimile
signature shall appear upon any of the Subordinated
Debentures shall cease to be such a representative before the
Subordinated Debentures so executed shall actually have been
authenticated or delivered, such Subordinated Debentures
nevertheless may be authenticated, issued and delivered with
the same force and effect as though the person who executed
such Subordinated Debentures had not ceased to be such
representative of Corning.

1.4   Term of the Subordinated Debentures.  
The entire principal amount of the Subordinated Debentures
shall become due and payable, together with any accrued and
unpaid interest (and Additional Interest (as hereinafter
defined)) thereon, on the earliest of __________, 2024 or the
date upon which Corning Delaware is dissolved, liquidated,
wound-up or terminated (the "Maturity Date"), unless
previously paid or redeemed pursuant to their terms.

1.5  Optional Prepayment.  Corning will have
the right to prepay or redeem the Subordinated Debentures, in
whole or in part (together with any accrued but unpaid interest
(and Additional Interest) on the portion being prepaid), at any
time on or after ______, 1998, during the twelve-month
periods beginning on ________ in each of the following years
at the following prepayment prices including any accrued and
unpaid interest (and Additional Interest) (the "Prepayment
Price") (expressed as a percentage of the principal amount of
the Subordinated Debentures being prepaid):

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

1.6  Notice of Redemption.  Corning shall give
notice of any redemption or prepayment (a "Notice of
Redemption") to Corning Delaware not fewer than 35 days nor
more than 60 days prior to the date fixed for redemption or
prepayment (the "Redemption Date") of the Subordinated
Debentures.  Such Notice shall indicate the Redemption Date
and the principal amount of Subordinated Debentures to be
redeemed or prepaid and any accrued and unpaid interest (and
Additional Interest) thereon.  Corning shall give a copy of such
Notice of Redemption to the Agent together with instructions
and authority to pay such principal amount of Subordinated
Debentures together with any accrued and unpaid interest (and
Additional Interest) to the account of Corning Delaware
designated in such instructions.

1.7  Deposit of Prepayment Price.  On or prior
to 12:00 noon New York City time on a Redemption Date,
Corning shall deposit with the Agent an amount of money in
immediately available funds sufficient to pay the Prepayment
Price of all of the Subordinated Debentures to be prepaid on

Article II
Interest

2.1  Interest on the Subordinated Debentures. 
The Subordinated Debentures will bear interest at the rate of    
        % per annum from the date such Subordinated
Debentures are originally issued and sold by Corning to
Corning Delaware, payable monthly in arrears on the last day
of each calendar month of each year (each an "Interest
Payment Date"), commencing _______, 1994.  Interest will
compound monthly and will accrue at the rate of __% per
annum on any interest installment that is not paid when due or
during an extension of an interest payment period as set forth
in Section 2.2 below ("Additional Interest").  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 or Chicago are
authorized or required by law to close.

2.2  Extension of 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 an
interest payment period for up to 60 months, provided that
during the period of any such extension, interest will continue
to accrue and compound monthly.  Corning shall have the right
to make partial payments of interest during any extended
interest payment period.  At the end of any such extended
interest payment period, Corning shall pay all interest then
accrued and unpaid (together with Additional Interest thereon). 
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 at
least one Business Day prior to the earlier of (i) the Interest
Payment Date and (ii) the date Corning Delaware is required to
give notice of the record or payment date of any Dividend
payable on the Preferred Securities 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.

Article III
Payments

3.1  Method and Date of Payment.  (a)  Each
payment by Corning of principal and interest (including
Additional Interest) on the Subordinated Debentures shall be
made by Corning or the Agent to Corning Delaware in
immediately available funds at such place and to such account
as may be designated by Corning Delaware.

(b) Any moneys deposited with the Agent
for the payment of the principal of or interest on any
Subordinated Debentures remaining unclaimed for two years
after such principal or interest shall have become due and
payable shall be repaid to Corning, and Corning Delaware, as
holder of the Subordinated Debentures, shall thereafter look
only to Corning for any payment to which it may be entitled.  

Article IV
Subordination

4.1  Subordination.  (a) Corning and Corning
Delaware covenant and agree that the Subordinated Debentures
are subordinate and junior in right of payment to all Senior
Indebtedness (as defined below) of Corning.

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 on the date hereof or hereafter incurred, created or
assumed:

                             (i)   all indebtedness of Corning for money
              borrowed (including any indebtedness secured by a
              mortgage or other lien which is (a) 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 (b) 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;

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

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

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

                             (v)  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
              (i) or (ii) or lease obligations of the kind described in
              the preceding clause (iii); and

                             (vi)  all renewals, extensions or refundings of
              indebtedness of the kinds described in any of the
              preceding clause (i), (ii) or (iv), all renewals or
              extensions of lease obligations of the kinds described in
              either of the preceding clauses (iii) and (iv) and all
              renewals or extensions of obligations with respect to
              letters of credit of the kind described in the preceding
              clause (v);

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. 

(b) In the event of (i) any insolvency or
bankruptcy case or proceeding, or any receivership, liquidation,
reorganization or other similar case or proceeding in connec-
tion therewith, relative to Corning or to its creditors, as such,
or to its assets, or (ii) any liquidation, dissolution or other
winding up of Corning whether voluntary or involuntary and
whether or not involving insolvency or bankruptcy, or (iii) any
assignment for the benefit of creditors or any other marshalling
of assets and liabilities of Corning, then and in any such event
the holders of Senior Indebtedness shall be entitled to receive
payment in full of all amounts due or to become due on or in
respect of all Senior Indebtedness, or provision shall be made
for such payment in money or money's worth, before the
holders of the Subordinated Debentures are entitled to receive
any payment on account of principal of or interest on the
Subordinated Debentures, and to that end the holders of Senior
Indebtedness shall be entitled to receive, for application to the
payment thereof, any payment or distribution of any kind or
character, whether in cash, property or securities, which may
be payable or deliverable in respect of the Subordinated
Debentures in any such case, proceeding, dissolution,
liquidation or other winding up or event.

In the event that, notwithstanding the foregoing
provisions of this Section 4.1, the holder of Subordinated
Debentures shall have received any payment or distribution of
assets of Corning of any kind or character, whether in cash,
property or securities, before all Senior Indebtedness is paid in
full or payment thereof provided for, and if such fact shall, at
or prior to the time of such payment or distribution, have been
made known to such holder, then and in such event such
payment or distribution shall be paid over or delivered
forthwith to the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee, agent or other person making
payment or distribution of assets of Corning for application to
the payment of all Senior Indebtedness remaining unpaid, to
the extent necessary to pay all Senior Indebtedness in full,
after giving effect to any concurrent payment or distribution to
or for the holders of Senior Indebtedness.

For purposes of this Section 4.1 only, the words
"cash, property or securities" shall not be deemed to include
shares of stock of Corning as reorganized or readjusted, or
securities of Corning or any other corporation provided for by
a plan of reorganization or readjustment which are
subordinated in right of payment to all Senior Indebtedness
which may at the time be outstanding to substantially the same
extent as, or to a greater extent than, the Subordinated
Debentures are so subordinated.  

The consolidation of Corning with, or the
merger of Corning into, another entity or the liquidation or
dissolution of Corning following the conveyance or transfer of
its properties and assets substantially as an entirety to another
Person upon the terms and conditions set forth in Limited
Partnership Agreement shall not be deemed a dissolution,
winding up, liquidation, reorganization, assignment for the
benefit of creditors or marshalling of assets and liabilities of
Corning for the purposes of this Section 4.1(b) if the entity
formed by such consolidation or into which Corning is merged
or the entity which acquires by conveyance or transfer such
properties and assets substantially as an entirety, as the case
may be, shall, as a part of such consolidation, merger,
conveyance or transfer, comply with the conditions set forth in
Limited Partnership Agreement.

(c) In the event that the Subordinated
Debentures are declared due and payable before the Maturity
Date, then and in such event the holders of Senior
Indebtedness outstanding at the time such Subordinated
Debentures so become due and payable shall be entitled to
receive payment in full of all amounts due on or in respect of
such Senior Indebtedness, or provision shall be made for such
payment in money or money's worth, before the holders of the
Subordinated Debentures are entitled to receive any payment
by Corning on account of the principal of or interest on the
Subordinated Debentures or on account of the purchase or
other acquisition of Subordinated Debentures.

In the event that, notwithstanding the foregoing,
Corning shall make any payment to any the holder of the
Subordinated Debentures prohibited by the foregoing
provisions, and if such fact shall, at or prior to the time of
such payment, have been made known to such holder, then and
in such event such payment shall be paid over and delivered
forthwith to Corning.

The provisions of this paragraph (c) shall not
apply to any payment with respect to which paragraph (b)
would be applicable.

(d)  In the event and during the continuation of
any default in the payment of principal of (or premium, if any)
or interest on any Senior Indebtedness beyond any applicable
grace period with respect thereto, or in the event that any event
of default with respect to any Senior Indebtedness shall have
occurred and be continuing and shall have resulted in such
Senior Indebtedness becoming or being declared due and
payable prior to the date on which it would otherwise have
become due and payable, unless and until such event of default
shall have been cured or waived or shall have ceased to exist
and such acceleration shall have been rescinded or annulled, or
(b) in the event any judicial proceeding shall be pending with
respect to any such default in payment or event of default, then
no payment shall be made by Corning on account of principal
of or interest on the Subordinated Debentures or on account of
the purchase or other acquisition of the Subordinated
Debentures.

In the event that, notwithstanding the foregoing,
Corning shall make any payment to the holder of the
Subordinated Debentures prohibited by the foregoing
provisions of paragraph (d), and if such fact shall, at or prior
to the time of such payment, have been made known to such
holder, then and in such event such payment shall be paid over
and delivered forthwith to Corning.

The provisions of this paragraph (d) shall not
apply to any payment with respect to which paragraph (b)
would be applicable.

(e) Nothing contained in this Agreement or
in any of the Subordinated Debentures shall prevent Corning,
at any time except during the pendency of any case,
proceeding, dissolution, liquidation or other winding up,
assignment for the benefit of creditors or other marshalling of
assets and liabilities of Corning referred to in paragraph (b) or
under the conditions described in paragraphs (c) or (d), from
making payments at any time of principal of or interest on the
Subordinated Debentures.

(f) Subject to the payment in full of all
Senior Indebtedness, the holders of the Subordinated
Debentures shall be subrogated to the rights of the holders of
such Senior Indebtedness to receive payments and distributions
of cash, property and securities applicable to the Senior
Indebtedness until the principal of and interest on the
Subordinated Debentures shall be paid in full.  For purposes of
such subrogation, no payments or distributions to the holders
of the Senior Indebtedness of any cash, property or securities
to which the holders of the Subordinated Debentures would be
entitled except for the provisions of this Section 4.1, and no
payments over pursuant to the provisions of this Section 4.1 to
the holders of Senior Indebtedness by holders of the
Subordinated Debentures, shall, as among Corning, its creditors
other than holders of Senior Indebtedness and the holders of
the Subordinated Debentures, be deemed to be a payment or
distribution by Corning to or on account of the Senior
Indebtedness.

(g) The provisions of this Section 4.1 are
and are intended solely for the purpose of defining the relative
rights of the holders of the Subordinated Debentures on the
one hand and the holders of Senior Indebtedness on the other
hand.  Nothing contained in this Article or elsewhere in this
Agreement or in the Subordinated Debentures is intended to or
shall (a) impair, as among Corning, its creditors other than
holders of Senior Indebtedness and the holders of the
Subordinated Debentures, the obligation of Corning, which is
absolute and unconditional, to pay to the holder of the
Subordinated Debentures the principal of (and premium, if any)
and interest on the Subordinated Debentures as and when the
same shall become due and payable in accordance with their
terms; or (b) affect the relative rights against Corning of the
holders of the Subordinated Debentures and creditors of
Corning other than the holders of Senior Indebtedness; or
(c) prevent the holders of any Subordinated Debentures from
exercising all remedies otherwise permitted by applicable law
upon default under this Agreement, subject to the rights, if
any, under this Section 4.1 of the holders of Senior
Indebtedness to receive cash, property and securities otherwise
payable or deliverable to such holder.

(h) No right of any present or future holder
of any Senior Indebtedness to enforce subordination as herein
provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of Corning or
by any act or failure to act, in good faith, by any such holder,
or by any non-compliance by Corning with the terms,
provisions and covenants of this Agreement, regardless of any
knowledge thereof any such holder may have or be otherwise
charged with.

Without in any way limiting the generality of
the foregoing paragraph, the holders of Senior Indebtedness
may, at any time and from time to time, without the consent of
or notice to the holders of the Subordinated Debentures,
without incurring responsibility to the holders of the
Subordinated Debentures and without impairing or releasing
the subordination provided in this Section 4.1 or the
obligations hereunder of the holders of the Subordinated
Debentures to the holders of Senior Indebtedness, do any one
or more of the following:  (i) change the manner, place or
terms of payment or extend the time of payment of, or renew
or alter, Senior Indebtedness, or otherwise amend or
supplement in any manner Senior Indebtedness or any
instrument evidencing the same or any agreement under which
Senior Indebtedness is outstanding; (ii) sell, exchange, release
or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Indebtedness; (iii) release any person
liable in any manner for the collection of Senior Indebtedness;
and (iv) exercise or refrain from exercising any rights against
Corning and any other person.

              good standing under the laws of the State of New York,
              with all power and authority (corporate and other) to

              Agreement and the performance by Corning of all its
              obligations hereunder will not conflict with or result in
              a breach or violation of any of the terms or provisions
              of, or constitute a default under, any indenture,
              mortgage, deed of trust, loan agreement, fiscal agency
              agreement or other agreement or instrument to which
              Corning is a party or by which Corning is bound or
              subject, nor will this Agreement result in a violation of
              the provisions of the Corning Certificate of

              accordance with their respective terms, subject, as to
              enforcement, to bankruptcy, insolvency, fraudulent
              transfer, reorganization, moratorium and similar laws of
              general applicability relating to or affecting creditors'
              rights and to general equity principles.


Article VI

Covenants

6.1  Covenants.  Corning agrees 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
(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 (a) 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
hereunder or under the Subordinated Debentures, (b) Corning
shall be in default with respect to its payment obligations
under the Guarantee or (c) Corning shall have given notice of
its selection of an extended interest payment period as
provided herein and such period, or any extension thereof shall
be continuing; provided, however, that Corning may declare
dividends on the Preferred Securities and any Pari Passu Stock
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 Cumulative Convertible
Preferred Stock, par value $100 per share (the "Series B
Preferred Stock"), and any series or class of preferred stock
issued by Corning, or any guarantee now or hereafter entered
into by Corning in respect of any preferred or preference stock
of any affiliate of Corning, ranking, in each case as to the
payment of dividends and amounts upon liquidation,
dissolution and winding-up on a parity with the Series B
Preferred Stock.   "Junior Stock" means Corning Common
Stock, the Series A Preferred Stock, par value $100 per share,
of Corning and any other class or series of capital stock of
Corning or any of its affiliates which by its express terms
ranks junior in the payment of dividends or amounts upon
liquidation, dissolution or winding-up to the Series B Preferred
Stock.  Corning also covenants (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 a General Partner of Corning Delaware, (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 declare and pay Dividends on the
Preferred Securities), (v) to maintain direct ownership of all
partnership interests of Corning Delaware other than the
Preferred Securities and any Special General Partnership
Interest, except as permitted by Section 11.2 of this
Agreement, (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 issue Corning Series C
Preferred Stock or Corning Common Stock upon an election
by Corning Delaware to exchange or convert the Subordinated
Debentures.

Corning also covenants that so long as any
Subordinated Debentures are held by Corning Delaware, the
General Partner shall not (i) direct the time, method and place
of conducting any proceeding for any remedy available to the
Special General Partner, or 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 this 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 this Fiscal Agency Agreement
without, in each case, obtaining the prior approval of the
holders of at least 66 2/3% or more of the aggregate
liquidation preference of the Preferred Securities then
outstanding, provided, however, that where a consent under the
Subordinated Debentures would require the consent of each
holder affected thereby, no such consent shall be given by the 
General Partner without the prior consent of each holder of the
Preferred Securities.  The General Partner shall not revoke any
action previously authorized or approved by a vote of Preferred
Securities, without the approval of the holders of Preferred
Securities representing 66 2/3% or more of the aggregate
liquidation preference of the Preferred Securities then
outstanding.  The General Partner shall notify all holders of
Preferred Securities of any notice of default received from the
Fiscal Agent with respect to the Subordinated Debentures.                 


Article VII

Events of Default

7.1  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 pursuant to
              Section 2.2 of this Agreement shall not constitute a
              default in the payment of interest for this purpose;

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

                             (d)  failure by Corning to perform in any
              material respect any other covenant herein 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)  the bankruptcy, insolvency or liquidation of
              Corning,
                             
then Corning Delaware, or any subsequent holder of
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 hereunder to be forthwith due and payable and to
enforce its other rights as a creditor with respect to the
Subordinated Debentures.  Upon any such declaration of
acceleration, the principal of and all accrued interest on the
Subordinated Debentures shall immediately become due and
payable.  Corning expressly acknowledges that, under the
terms of the Preferred Securities, the holders of outstanding
Preferred Securities shall have the right to appoint a Special
General Partner, which Special General Partner shall be
authorized to exercise Corning Delaware's right to accelerate
the principal amount of the Subordinated Debentures and to
enforce Corning Delaware's other rights hereunder and under
the Subordinated Debentures.


Article VIII

Conversion of the Subordinated Debentures

8.1  Conversion Rights.   (a)  The Subordinated
Debentures are convertible at any time on or before the close
of business on the Maturity Date at the option of Corning
Delaware into shares of common stock, par value $.50 per
share, of Corning ("Corning Common Stock") at an initial
conversion price of $_____ per share of Corning Common
Stock, subject to adjustment as described herein.   The holder
of Subordinated Debentures may convert any portion of the
principal amount of the Subordinated Debentures into that
number of fully paid and non-assessable shares of Corning
Common Stock (calculated as to each conversion to the nearest
1/100th of a share) obtained by dividing the principal amount
of the Subordinated Debentures to be converted by such
conversion price.

(b)  In order to convert a portion of the
Subordinated Debentures, Corning Delaware shall deliver a
notice of conversion (a "Notice of Conversion") to Corning
and the Agent, setting forth the principal amount of
Subordinated Debentures to be converted, together with the
name or names in which the shares of Corning Common Stock
should be issued upon conversion.  In the case of a Notice of
Conversion given on the Business Day immediately preceding
the next Interest Payment Date, Corning Delaware will be
entitled to receive the interest payable on the portion of
Subordinated Debentures to be converted on the Interest
Payment Date notwithstanding the conversion thereof on such
Interest Payment Date.   Each conversion will be deemed to
have been effected immediately prior to the close of business
on the day on which the notice was received (the "Conversion
Date") by Corning Delaware from a holder of the Preferred
Securities effecting a conversion thereof pursuant to its
conversion rights under the Limited Partnership Agreement. 
Upon conversion of the Subordinated Debentures, Corning will
not make, nor be required to make, any other payment,
adjustment or allowance with respect to accrued but unpaid
interest on the Subordinated Debentures being converted.  The
Person or Persons entitled to receive the Corning Common
Stock issuable upon such conversion shall be treated for all
purposes as the record holder or holders of such Common
Stock as of the Conversion Date.  As promptly as practicable
on or after the Conversion Date, Corning shall issue and
deliver at the office of the Agent, unless otherwise directed by
the Holder in the Notice of Conversion, a certificate or
certificates for the number of full shares of Common Stock
issuable upon such conversion, together with the cash payment,
if any, in lieu of any fraction of any share to the Person or
Persons entitled to receive the same.  The Agent shall deliver
such certificate or certificates to such Person or Persons. 

(c)  Corning's delivery 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) shall be deemed to satisfy
Corning's obligation to pay the principal amount at maturity of
the portion of Subordinated Debentures so converted and any
unpaid interest accrued on such portion of Subordinated
Debentures at the time of such conversion.

(d)  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 by
Corning.

8.2  Conversion Price Adjustments.  (a)  The
conversion price shall be subject to adjustment from time to
time as follows:

                             (i)            In case Corning shall pay or make a
              dividend or other distribution on any class or series of
              capital stock of Corning exclusively in Corning
              Common Stock, the conversion price in effect at the
              opening of business on the day following the date fixed
              for the determination of stockholders entitled to receive
              such dividend or other distribution shall be reduced by
              multiplying such conversion price by a fraction of
              which the numerator shall be the number of shares of
              Corning Common Stock outstanding at the close of
              business on the date fixed for such determination and
              the denominator shall be the sum of such number of
              shares and the total number of shares constituting such
              dividend or other distribution or exchange, such
              reduction to become effective immediately after the
              opening of business on the day following the date fixed
              for such determination.  For the purposes of this
              subparagraph (i), the number of shares of Corning
              Common Stock at any time outstanding shall not
              include shares held in the treasury of Corning.  Corning
              shall not pay any dividend or make any distribution on
              shares of any class or series of Capital Stock of
              Corning exclusively in Corning Common Stock held in
              the treasury of Corning.

                             (ii)           In case Corning shall pay or make a
              dividend or other distribution on its Corning Common
              Stock consisting exclusively of, or shall otherwise issue
              to all holders of its Corning Common Stock, rights or
              warrants entitling the holders thereof to subscribe for or
              purchase shares of Corning Common Stock at a price
              per share less than the current market price per share
              (determined as provided in subparagraph (vii) of this
              Section 8.2(a)) of the Corning Common Stock on the
              date fixed for the determination of stockholders entitled
              to receive such rights or warrants, the conversion price
              in effect at the opening of business on the day
              following the date fixed for such determination shall be
              reduced by multiplying such conversion price by a
              fraction of which the numerator shall be the number of
              shares of Corning Common Stock outstanding at the
              close of business on the date fixed for such
              determination plus the number of shares of Corning
              Common Stock which the aggregate of the offering
              price of the total number of shares of Corning Common
              Stock so offered for subscription or purchase would
              purchase at such current market price and the
              denominator shall be the number of shares of Corning
              Common Stock outstanding at the close of business on
              the date fixed for such determination plus the number
              of shares of Corning Common Stock so offered for
              subscription or purchase, such reduction to become
              effective immediately after the opening of business on
              the day following the date fixed for such determination. 
              For the purposes of this subparagraph (ii), the number
              of shares of Corning Common Stock at any time
              outstanding shall not include shares held in the treasury
              of Corning.  Corning shall not issue any rights or
              warrants in respect of shares of Corning Common Stock
              held in the treasury of Corning.  In case any rights or
              warrants referred to in this subparagraph (ii) in respect
              of which an adjustment shall have been made shall
              expire unexercised within 45 days after the same shall
              have been distributed or issued by Corning, the
              conversion price shall be readjusted at the time of such
              expiration to the conversion price that would have been
              in effect if no adjustment had been made on account of
              the distribution or issuance of such expired rights or
              warrants.

                             (iii)    In case outstanding shares of Corning
              Common Stock shall be subdivided into a greater
              number of shares of Corning Common Stock, the
              conversion price in effect at the opening of business on
              the day following the day upon which such subdivision
              becomes effective shall be proportionately reduced, and
              conversely, in case outstanding shares of Corning
              Common Stock shall each be combined into a smaller
              number of shares of Corning Common Stock, the
              conversion price in effect at the opening of business on
              the day following the day upon which such combination
              becomes effective shall be proportionately increased,
              such reduction or increase, as the case may be, to
              become effective immediately after the opening of
              business on the day following the day upon which such
              subdivision or combination becomes effective.

                             (iv)   Subject to the last sentence of this sub-
              paragraph (iv), in case Corning shall, by dividend or
              otherwise, distribute to all holders of its Corning
              Common Stock evidences of its indebtedness, shares of
              any class or series of capital stock, cash or assets
              (including securities, but excluding any rights or
              warrants referred to in subparagraph (ii) of this
              Section 8.2(a), any dividend or distribution paid
              exclusively in cash and any dividend or distribution
              referred to in subparagraph (i) of this Section 8.2(a)),
              the conversion price shall be reduced so that the same
              shall equal the price determined by multiplying the
              conversion price in effect immediately prior to the
              effectiveness of the conversion price reduction
              contemplated by this subparagraph (iv) by a fraction of
              which the numerator shall be the current market price
              per share (determined as provided in subparagraph (vii)
              of this Section 8.2(a)) of the Corning Common Stock
              on the date fixed for the payment of such distribution
              (the "Reference Date") less the fair market value (as
              determined in good faith by the Board of Directors,
              whose determination shall be conclusive and described
              in a resolution of the Board of Directors), on the
              Reference Date, of the portion of the evidences of
              indebtedness, shares of capital stock, cash and assets so
              distributed applicable to one share of Corning Common
              Stock and the denominator shall be such current market
              price per share of the Corning Common Stock, such
              reduction to become effective immediately prior to the
              opening of business on the day following the Reference
              Date.  If the Board of Directors determines the fair
              market value of any distribution for purposes of this
              subparagraph (iv) by reference to the actual or when
              issued trading market for any securities comprising such
              distribution, it must in doing so consider the prices in
              such market over the same period used in computing
              the current market price per share of Corning Common
              Stock pursuant to subparagraph (vii) of this
              Section 8.2(a).  For purposes of this subparagraph (iv),
              any dividend or distribution that includes shares of
              Corning Common Stock or rights or warrants to
              subscribe for or purchase shares of Corning Common
              Stock shall be deemed instead to be (1) a dividend or
              distribution of the evidences of indebtedness, shares of
              capital stock, cash or assets other than such shares of
              Corning Common Stock or such rights or warrants
              (making any conversion price reduction required by this
              subparagraph (iv)) immediately followed by (2) a
              dividend or distribution of such shares of Corning
              Common Stock or such rights or warrants (making any
              further conversion price reduction required by
              subparagraph (i) or (ii) of this Section 8.2(a), except
              (A) the Reference Date of such dividend or distribution
              as defined in this subparagraph (iv) shall be substituted
              as "the date fixed for the determination of stockholders
              entitled to receive such dividend or other distribution,"
              "the date fixed for the determination of stockholders
              entitled to receive such rights or warrants" and "the
              date fixed for such determination" within the meaning
              of subparagraphs (i) and (ii) of this Section 8.2(a) and
              (B) any shares of Corning Common Stock included in
              such dividend or distribution shall not be deemed
              "outstanding at the close of business on the date fixed
              for such determination" within the meaning of sub-
              paragraph (i) of this Section 8.2(a).

                             (v) In case Corning shall pay or make a
              dividend or other distribution on its Corning Common
              Stock exclusively in cash (excluding, in the case of any
              regular cash dividend on the Corning Common Stock,
              the portion thereof that does not exceed the per share
              amount of the next preceding regular cash dividend on
              the Corning Common Stock (as adjusted to
              appropriately reflect any of the events referred to in
              subparagraphs (i), (ii), (iii), (iv), (v) and (vi) of this
              Section 8.2(a)), or all of such regular cash dividend if
              the annualized amount thereof per share of Corning
              Common Stock does not exceed 15% of the current
              market price per share (determined as provided in
              subparagraph (vii) of this Section 8.2(a) of the Corning
              Common Stock on the Trading Day (as defined in
              Section 8.2(e)) next preceding the date of declaration of
              such dividend), the conversion price shall be reduced so
              that the same shall equal the price determined by
              multiplying the conversion price in effect immediately
              prior to the effectiveness of the conversion price
              reduction contemplated by this subparagraph (v) by a
              fraction of which the numerator shall be the current
              market price per share (determined as provided in
              subparagraph (vii) of this Section 8.2(a)) of the Corning
              Common Stock on the date fixed for the payment of
              such distribution less the amount of cash so distributed
              and not excluded as provided above applicable to one
              share of Corning Common Stock and the denominator
              shall be such current market price per share of the
              Corning Common Stock, such reduction to become
              effective immediately prior to the opening of business
              on the day following the date fixed for the payment of
              such distribution.

                             (vi) In case a tender or exchange offer made
              by Corning or any subsidiary of Corning for all or any
              portion of Corning's Corning Common Stock shall
              expire and such tender or exchange offer shall involve
              the payment by Corning or such subsidiary of
              consideration per share of Corning Common Stock
              having a fair market value (as determined in good faith
              by the Board of Directors, whose determination shall be
              conclusive and described in a resolution of the Board of
              Directors) at the last time (the "Expiration Time")
              tenders or exchanges may be made pursuant to such
              tender or exchange offer (as it shall have been
              amended) that exceeds 10% of the current market price
              per share (determined as provided in subparagraph (vii)
              of this Section 8.2(a)) of the Corning Common Stock
              on the Trading Day (as defined in Section 8.2(e)) next
              succeeding the Expiration Time, the conversion price
              shall be reduced so that the same shall equal the price
              determined by multiplying the conversion price in effect
              immediately prior to the effectiveness of the conversion
              price reduction contemplated by this subparagraph (vi)
              by a fraction of which the numerator shall be the
              number of shares of Corning Common Stock
              outstanding (including any tendered or exchanged
              shares) at the Expiration Time multiplied by the current
              market price per share (determined as provided in
              subparagraph (vii) of this Section 8.2(a)) of the Corning
              Common Stock on the Trading Day next succeeding the
              Expiration Time and the denominator shall be the sum
              of (x) the fair market value (determined as aforesaid) of
              the aggregate consideration payable to stockholders
              based on the acceptance (up to any maximum specified
              in the terms of the tender or exchange offer) of all
              shares validly tendered or exchanged and not withdrawn
              as of the Expiration Time (the shares deemed so
              accepted, up to any such maximum, being referred to as
              the "Purchased Shares") and (y) the product of the
              number of shares of Corning Common Stock
              outstanding (less any Purchased Shares) at the
              Expiration Time and the current market price per share
              (determined as provided in subparagraph (vii) of this
              Section 8.2(a)) of the Corning Common Stock on the
              Trading Day next succeeding the Expiration Time, such
              reduction to become effective immediately prior to the
              opening of business on the day following the Expiration
              Time.

                             (vii) For the purpose of any computation
              under subparagraphs (ii), (iv) and (v) and (vi) of this
              Section 8.2(a), the current market price per share of
              Corning Common Stock on any date in question shall
              be deemed to be the average of the daily Closing Prices
              (as defined in Section 8.2(e)) for the for the five
              consecutive Trading Days selected by the Company
              commencing not more than 20 Trading Days before,
              and ending not later than, the earlier of the day in
              question and, if applicable, the day before the "ex" date
              with respect to the issuance or distribution requiring
              such computation; provided, however, that in each
              event another event occurs that would require an
              adjustment pursuant to subparagraph (i) through (vi),
              inclusive, the Board of Directors may make such
              adjustments to the Closing Prices during such five
              Trading Day period as it deems appropriate to
              effectuate the intent of the adjustments in this Section
              8.2(a), any such determination by the Board of
              Directors shall be set forth in a Board Resolution and
              shall be conclusive.  For purposes of this paragraph, the
              term "ex" date, (1) when used with respect to any
              issuance or distribution, means the first date on which
              the Corning Common Stock trades regular way on the
              relevant exchange or in the relevant market from which
              the Closing Price was obtained without the right to
              receive such issuance or distribution, and (2) when used
              with respect to any tender or exchange offer means the
              first date on which the Corning Common Stock trades
              regular way on such exchange or in such market after
              the Expiration Time of such offer.

                             (viii) Corning may make such reductions in the
              conversion price, in addition to those required by
              subparagraphs (i), (ii), (iii), (iv), (v) and (vi) of this
              Section 8.2(a), as it considers to be advisable to avoid
              or diminish any income tax to holders of Corning
              Common Stock or rights to purchase 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.  Corning from
              time to time may reduce the conversion price by any
              amount for any period of time if the period is at least
              twenty days, the reduction is irrevocable during the
              period, and the Board of Directors of Corning shall
              have made a determination that such reduction would
              be in the best interest of Corning, which determination
              shall be conclusive.  Whenever the conversion price is
              reduced pursuant to the preceding sentence, Corning
              shall mail to holders of record of the Subordinated
              Debentures a notice of the reduction at least fifteen
              days prior to the date the reduced conversion price
              takes effect, and such notice shall state the reduced
              conversion price and the period it will be in effect.

                             (ix) No adjustment in the conversion price
              shall be required unless such adjustment would require
              an increase or decrease of at least 1% in the conversion
              price; provided, however, that any adjustments which
              by reason of this subparagraph (ix) are not required to
              be made shall be carried forward and taken into account
              in any subsequent adjustment.

                             (x)  Whenever the conversion price is
              adjusted as herein provided:

                                            (1) Corning shall compute the
                             adjusted conversion price and shall prepare a
                             certificate signed by the Treasurer of Corning
                             setting forth the adjusted conversion price and
                             showing in reasonable detail the facts upon
                             which such adjustment is based, and such
                             certificate shall forthwith be filed with the
                             transfer agent for the Preferred Securities; and

                                            (2) a notice stating the conversion
                             price has been adjusted and setting forth the
                             adjusted conversion price shall forthwith be
                             required, and as soon as practicable after it is
                             required such notice shall be mailed by Corning
                             to all record holders of Preferred Securities at
                             their last addresses as they shall appear upon the
                             stock transfer books of Corning.

(b)            Reclassification, Consolidation, Merger
or Sale of Assets.  In the event that Corning shall be a party to
any transaction (including without limitation any
recapitalization or reclassification of the Corning Common
Stock (other than a change in par value, or from par value to
no par value, or from no par value to par value, or as a result
of a subdivision or combination of the Corning Common
Stock), any consolidation of Corning with, or merger of
Corning into, any other person, any merger of another person
into Corning (other than a merger which does not result in a
reclassification, conversion, exchange or cancellation of
outstanding shares of Corning Common Stock of Corning), any
sale or transfer of all or substantially all of the assets of
Corning or any compulsory share exchange) pursuant to which
the Corning Common Stock is converted into the right to
receive other securities, cash or other property), then lawful
provisions shall be made as part of the terms of such
transaction whereby the holder of each Subordinated Debenture
then outstanding shall have the right thereafter to convert such
share only into (i) in the case of any such transaction other
than a Common Stock Fundamental Change (as defined in
Section 8.2(e)), the kind and amount of securities, cash and
other property receivable upon such transaction by a holder of
the number of shares of Corning Common Stock of Corning
into which such Subordinated Debenture could have been
converted immediately prior to such transaction, after giving
effect, in the case of any Non-Stock Fundamental Change, to
any adjustment in the conversion price required by the
provisions of Section 8.2(d), and (ii) in the case of a Common
Stock Fundamental Change, common stock of the kind
received by holders of Corning Common Stock as a result of
such Common Stock Fundamental Change in an amount
determined pursuant to the provisions of Section 8.2(d). 
Corning or the person formed by such consolidation or
resulting from such merger or which acquires such assets or
which acquires Corning's shares, as the case may be, shall
make provisions in its certificate or articles of incorporation or
other constituent document to establish such right.  Such
certificate or articles of incorporation or other constituent
document shall provide for adjustments which, for events
subsequent to the effective date of such certificate or articles of
incorporation or other constituent document, shall be as nearly
equivalent as may be practicable to the adjustments provided
for in this Section 8.2.  The above provisions shall similarly
apply to successive transactions of the foregoing type.

                             (c)  Prior Notice of Certain Events.  In case:

                             (i)  Corning shall (1) declare any dividend
              (or any other distribution) on its Corning Common
              Stock, other than (A) a dividend payable in shares of
              Corning Common Stock or (B) a dividend payable in
              cash that would not require an adjustment pursuant to
              8.2(a)(iv) or (v) or other extraordinary dividend or
              (2) authorize a tender or exchange offer that would
              require an adjustment pursuant to Section 8.2(a)(vi); or

                             (ii)   Corning shall authorize the granting to
              all holders of Corning Common Stock of rights or
              warrants to subscribe for or purchase any shares of
              stock of any class or series or of any other rights or
              warrants; or

                             (iii) of any reclassification of Corning
              Common Stock (other than a subdivision or
              combination of the outstanding Corning Common
              Stock, or a change in par value, or from par value to no
              par value, or from no par value to par value), or of any
              consolidation or merger to which Corning is a party and
              for which approval of any stockholders of Corning shall
              be required, or of the sale or transfer of all or
              substantially all of the assets of Corning or of any
              compulsory share exchange whereby the Corning
              Common Stock is converted into other securities, cash
              or other property; or

                             (iv)  of the voluntary or involuntary
              dissolution, liquidation or winding up of Corning;

then Corning shall cause to be filed with the transfer agent for
the Preferred Securities, and shall cause to be mailed to the
holders of record of the Preferred Securities, at their last
addresses as they shall appear upon the stock transfer books of
Corning, at least fifteen days prior to the applicable record or
effective date hereinafter specified, a notice stating (x) the date
on which a record (if any) is to be taken for the purpose of
such dividend, distribution, redemption, repurchase, rights or
warrants or, if a record is not to be taken, the date as of which
the holders of Corning Common Stock of record to be entitled
to such dividend, distribution, redemption, repurchase, rights or
warrants are to be determined or (y) the date on which such
reclassification, consolidation, merger, sale, transfer, share
exchange, dissolution, liquidation or winding up is expected to
become effective, and the date as of which it is expected that
holders of Corning Common Stock of record shall be entitled
to exchange their shares of Corning Common Stock for
securities, cash or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, share
exchange, dissolution, liquidation or winding up (but no failure
to mail such notice or any defect therein or in the mailing
thereof shall affect the validity of the corporate action required
to be specified in such notice).

                             (d) Adjustments in Case of Fundamental
Changes.  Notwithstanding any other provision in this Section
8.2 to the contrary, if any Fundamental Change (as defined in
Section 8.2(e)) occurs, then the conversion price in effect will
be adjusted immediately after such Fundamental Change as
described below.  In addition, in the event of a Common Stock
Fundamental Change (as defined in Section 8.2(e)), each
Subordinated Debenture shall be convertible solely into
common stock of the kind and amount received by holders of
Corning Common Stock as the result of such Common Stock
Fundamental Change as more specifically provided in the
following clauses (d)(i) and (d)(ii). 

For purposes of calculating any adjustment to be made
pursuant to this Section 8.2(d) in the event of a Fundamental
Change, immediately after such Fundamental Change: 

                             (i) in the case of a Non-Stock Fundamental
              Change (as defined in Section 8.2(e)), the conversion
              price of the Subordinated Debentures shall 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 effected pursuant to this Section 8.2, and
              (B) the result obtained by multiplying the greater of the
              Applicable Price (as defined in Section 8.2(e)) or the
              then applicable Reference Market Price (as defined in
              Section 8.2(e)) by a fraction of which the numerator
              shall be $50.00 and the denominator shall be (x) the
              then-current Redemption Price for the Subordinated
              Debentures or (y) for any Non-Stock Fundamental
              Change that occurs before the Subordinated Debentures
              become redeemable by Corning pursuant to Section 1.4,
              the applicable price (expressed as a percentage of the
              principal amount of Subordinated Debentures) set forth
              for the date of such Non-Stock Fundamental Change in
              the following table:

Date of Non-Stock Fundamental Change              (% of principal
                                                  amount)

     After date of original issuance of Subordinated Debentures and 
on or before _____ ___, 1995 ___%  

After _____ ___, 1995, and on or before _____ ___, 1996 

After _____ ___, 1996, and on or before _____ ___, 1997

After _____ ___, 1997, and on or before _____ ___, 1998


              plus, in any case referred to in this clause (y), an
              amount equal to all interest on the Subordinated
              Debentures accrued and unpaid thereon, to but
              excluding the date of such Non-Stock Fundamental
              Change; and 

                             (ii)           in the case of a Common Stock
              Fundamental Change, the conversion price of the
              Subordinated Debentures in effect immediately prior to
              such Common Stock Fundamental Change, but after
              giving effect to any other prior adjustments effected
              pursuant to this Section 8.2, shall thereupon be adjusted
              by multiplying such conversion price by a fraction of
              which the numerator shall be the Purchaser Stock Price
              (as defined in Section 8.2(e)) and the denominator shall
              be the Applicable Price; provided, however, that in the
              event of a Common Stock Fundamental Change in
              which (A) 100% of the value of the consideration
              received by a holder of Corning Common Stock is
              common stock of the successor, acquiror or other third
              party (and cash, if any, is paid with respect to any
              fractional interests in such common stock resulting from
              such Common Stock Fundamental Change) and (B) all
              of the Corning Common Stock shall 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 Subordinated Debentures in
              effect immediately prior to such Common Stock
              Fundamental Change shall thereupon be adjusted by
              multiplying such conversion price by a fraction of
              which the numerator shall be one (1) and the
              denominator shall be the number of shares of common
              stock of the successor, acquiror, or other third party
              received by a stockholder for one share of Corning
              Common Stock as a result of such Common Stock
              Fundamental Change.

              (e) Definitions.  The following definitions shall apply to
terms used in this Section 8.2:

              (1) "Applicable Price" shall mean (i) in the event of a
              Non-Stock Fundamental Change in which the holders of
              the Corning Common Stock receive only cash, the
              amount of cash received by a stockholder for 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 daily
              Closing Prices of the Corning Common Stock for the
              ten consecutive Trading Days prior to and including the
              record date for the determination of the holders of
              Corning Common Stock entitled to receive 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, in each case, as
              adjusted in good faith by the Board of Directors of
              Corning to appropriately reflect any of the events
              referred to in subparagraphs (i), (ii), (iii), (iv), (v) and
              (vi) of Section 8.2(a).

              (2) "Closing Price" of any common stock on any day
              shall mean the last reported sale price regular way on
              such day or, in case no such sale takes place on such
              day, the average of the reported closing bid and asked
              prices regular way of the common stock in each case
              on the principal national securities exchange on which
              the Corning Common Stock is listed, if the Corning
              Common Stock is not listed on a national securities
              exchange or the National Market System of the
              National Association of Securities Dealers, Inc., or, if
              the common stock is not quoted or admitted to trading
              on such quotation system, on the principal quotation
              system on which the common stock is listed or
              admitted to trading or quoted, or, if not listed or
              admitted to trading or quoted on any national securities
              exchange or quotation system, the average of the
              closing bid and asked prices of the common stock in
              the over-the-counter market on the day in question as
              reported by the National Quotation Bureau
              Incorporated, or a similarly generally accepted reporting
              service, or, if not so available in such manner, as
              furnished by any New York Stock Exchange member
              firm selected from time to time by the Board of
              Directors of Corning for that purpose or, if not so
              available in such manner, as otherwise determined in
              good faith by the Board of Directors.

              (3) "Common Stock Fundamental Change" shall mean
              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
              referred to with respect to such Fundamental Change in
              Section 8.2(e)(1) above 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 Subordinated Debentures continue to exist
              as outstanding Subordinated Debentures, or (ii) not later
              than the occurrence of such Fundamental Change, the
              outstanding Subordinated Debentures are converted into
              or exchanged for convertible subordinated debentures of
              a corporation succeeding to the business of Corning,
              which convertible subordinated debentures have terms
              substantially similar to those of the Subordinated
              Debentures.

              (4) "Fundamental Change" shall mean 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, however, 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 of Corning 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 of consideration per share which a holder of
              Corning Common Stock could have received in such
              transactions or events as a result of which more than
              50% of the Corning Common Stock of Corning shall
              have been exchanged for, converted into, or acquired
              for or constitute solely the right to receive securities,
              cash or other property.

              (5) "Non-Stock Fundamental Change" shall mean any
              Fundamental Change other than a Common Stock
              Fundamental Change.

              (6) "Purchaser Stock Price" shall mean, with respect to
              any Common Stock Fundamental Change, the average
              of the daily Closing Prices of the common stock
              received in such Common Stock Fundamental Change
              for the ten consecutive Trading Days prior to and
              including the record date for the determination of the
              holders of Corning Common Stock entitled to receive
              such common stock, 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
              common stock, in each case, as adjusted in good faith
              by the Board of Directors of Corning to appropriately
              reflect any of the events referred to in subparagraphs
              (i), (ii), (iii), (iv), (v) and (vi) of Section 8.2(a);

              (7) "Reference Market Price" shall initially mean
              $_____ and in the event of any adjustment to the
              conversion price other than as a result of a Non-Stock
              Fundamental Change, the Reference Market Price shall
              also be adjusted so that the ratio of the Reference
              Market Price to the conversion price after giving effect
              to any such adjustment shall always be the same as the
              ratio of $_____ to the initial conversion price per share.

              (8) "Trading Day" shall mean a day on which securities
              traded on the national securities exchange or quotation
              system or in the over-the-counter market used to
              determine the Closing Price.

              (f) Dividend or Interest Reinvestment Plans. 
Notwithstanding the foregoing provisions, the issuance of any
shares of Corning Common Stock pursuant to any 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, and the issuance of any shares of Corning
Common Stock or options or rights to purchase such shares
pursuant to any 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 Subordinated Debentures were first issued, shall not be
deemed to constitute an issuance of Corning Common Stock or
exercisable, exchangeable or convertible securities by Corning
to which any of the adjustment provisions described above
applies.  There shall also be no adjustment of the conversion
price in case of the issuance of any stock (or securities
convertible into or exchangeable for stock) of Corning except
as specifically described in this Section 8.2.  If any action
would require adjustment of the conversion price pursuant to
more than one of the provisions described above, only one
adjustment shall be made and such adjustment shall be the
amount of adjustment that has the highest absolute value to the
holder of Subordinated Debentures.

              (g) Certain Additional Rights.  In case Corning shall,
by dividend or otherwise, declare or make a distribution on its
Corning Common Stock referred to in Section 8.2(a)(iv) or
8.2(a)(v) (including, without limitation, dividends or
distributions referred to in the last sentence of Section
8.2(a)(iv)), the holder of the Subordinated Debentures, upon
the conversion thereof subsequent to the close of business on
the date fixed for the determination of stockholders entitled to
receive such distribution and prior to the effectiveness of the
conversion price adjustment in respect of such distribution,
shall also be entitled to receive for each share of Corning
Common Stock into which the Subordinated Debentures are
converted, the portion of the shares of Corning Common
Stock, rights, warrants, evidences of indebtedness, shares of
capital stock, cash and assets so distributed applicable to one
share of Corning Common Stock; provided, however, that, at
the election of Corning (whose election shall be evidenced by
a resolution of the Board of Directors) with respect to all
holders so converting, Corning may, in lieu of distributing to
such holder any portion of such distribution not consisting of
cash or securities of Corning, pay such holder an amount in
cash equal to the fair market value thereof (as determined in
good faith by the Board of Directors, whose determination
shall be conclusive and described in a resolution of the Board
of Directors).  If any conversion of Subordinated Debentures
described in the immediately preceding sentence occurs prior
to the payment date for a distribution to holders of Corning
Common Stock which the holder of Subordinated Debentures
so converted is entitled to receive in accordance with the
immediately preceding sentence, Corning may elect (such
election to be evidenced by a resolution of the Board of
Directors) to distribute to such holder a due bill for the shares
of Corning Common Stock, rights, warrants, evidences of
indebtedness, shares of capital stock, cash or assets to which
such holder is so entitled, provided that such due bill (i) meets
any applicable requirements of the principal national securities
exchange or other market on which the Corning Common
Stock is then traded and (ii) requires payment or delivery of
such shares of Corning Common Stock, rights, warrants,
evidences of indebtedness, shares of capital stock, cash or
assets no later than the date of payment or delivery thereof to
holders of shares of Corning Common Stock receiving such
distribution.

Article IX

Exchange

              9.1 Optional Exchange for Corning Preferred Stock. 
For so long as the Subordinated Debentures are outstanding,
the Subordinated Debentures shall be exchangeable at the
request of Corning Delaware for shares of Corning Series C
Preferred Stock, subject to the following terms and conditions:

(a) Corning shall, after an Exchange Event shall occur, at the
request of Corning Delaware, exchange all (but not less than
all) of the Subordinated Debentures for shares of its Series C
Preferred Stock at the rate of one share of Corning Series C
Preferred Stock for each $100 principal amount of
Subordinated Debentures (which rate is equivalent to one share
of Corning Series C Preferred Stock for two Preferred
Securities).  

(b) The  following events are "Exchange Events":

(i) the failure of holders of Preferred Securities to receive, for
15 consecutive months (including any arrearage with respect to
the Preferred Securities) the full amount of dividend payments
on the Preferred Securities; and

(ii) a Tax Event.

(c) In order to exchange the Subordinated Debentures, Corning
Delaware, after receiving notice of an Exchange Election by
the holders of a Majority in Liquidation Preference of the
Preferred Securities, shall deliver an irrevocable notice of
exchange (a "Notice of Exchange") to Corning and the Agent. 
Upon receipt of such notice, Corning shall issue shares of its
Series C Preferred Stock in the names of the holders of
Preferred Securities designated in the Notice of Exchange in
exchange for the principal amount of the Subordinated
Debentures then outstanding.   Any accrued but unpaid interest
on the Subordinated Debentures surrendered for exchange,
including any Additional Interest accrued thereon, shall be
treated as accrued and unpaid dividends on the Corning Series
C Preferred Stock issued in exchange for the Subordinated
Debentures to the extent provided in paragraph 4C of the
Restated Certificate of Incorporation regarding such Corning
Series C Preferred Stock.  The Subordinated Debentures shall
be deemed to have been exchanged immediately prior to the
close of business on the date of the Exchange Election (the
"exchange date").  The Person or Persons entitled to receive
the Corning Series C Preferred  Stock issuable upon an
exchange of the Preferred Securities shall be treated for all
purposes as the record holder or holders of such  Series C
Preferred  Stock at such time.   As promptly as practicable on
or after the exchange date, Corning shall issue and deliver at
the office of the  Agent a certificate or certificates for the
number of shares of Corning Series C Preferred Stock issuable
upon such exchange, unless otherwise directed by Corning
Delaware in the Notice of Exchange.  


Article X

The Agent

                             
              10.1  Appointment of Agent.  Corning hereby appoints
Harris Trust and Savings Bank as its fiscal agent, registrar,
transfer agent and paying and conversion agent with respect to
the Subordinated Debentures (Harris Trust and Savings Bank

registration of transfer, exchange or conversion of Subordinated
Debentures, but the Agent may require payment of a sum
sufficient to cover any stamp or other tax or governmental
charge in connection therewith.

(b) Corning and the Agent may treat the person in whose name

(e) The Agent shall record in the register whether any
Subordinated Debentures have been redeemed or otherwise

absolute and uncontrolled discretion as to the exercise thereof
whether in relation to the manner or as to the mode of and
time for the exercise thereof and, in the absence of negligence

employees shall be in no way responsible for any loss, costs,
damages or inconvenience that may result from the exercise or
non-exercise thereof.

10.7  Signatures.  Unless herein otherwise specifically

America or the State of New York, in good standing and
having an established place of business in The City of New
York, and authorized under such laws to exercise corporate

No._____                                          $____


Corning Incorporated, a corporation duly organized and
existing under the laws of the State of New York (herein
called "Corning", which term includes any successor
corporation under the Fiscal Agency Agreement hereinafter
referred to), for value received, hereby promises to pay to
                                            , or registered
assigns, the principal sum of                 on ____________,
2024 and to pay interest at the rate of             % per annum
from the date of original issuance and sale, payable monthly in
arrears on the last day of each calendar month of each year
(each an "Interest Payment Date"), commencing               ,
1994.  Interest will compound monthly and will accrue at the
rate of __% per annum on any interest installment that is not
paid at the end of any monthly interest period or when
otherwise due ("Additional Interest").  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 or Chicago are authorized or required by
law to close.

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.  

Each payment by Corning of principal and interest on the
Subordinated Debentures shall be made to Corning Delaware
in immediately available funds in lawful money of the United
States at such place and to such account as may be designated
by Corning Delaware.  

Reference is hereby made to the further provisions of the
Fiscal Agency Agreement summarized on the reverse hereof,
which further provisions shall for all purposes have the same
effect as if set forth at this place.

Unless the certificate of authentication hereon has been
executed by the Fiscal Agent referred to on the reverse hereof
by manual signature, this Subordinated Debenture shall not be
entitled to any benefit under the Fiscal Agency Agreement or
be valid or obligatory for any purpose.

IN WITNESS WHEREOF, Corning has caused this
instrument to be duly executed under its corporate seal.

[FORM OF REVERSE OF SECURITY]


This Convertible Subordinated Debenture is one of a duly
authorized issue of securities of Corning (herein called the
"Subordinated Debentures"), issued under a Fiscal Agency
Agreement, dated as of _______________ (herein called the
"Fiscal Agency Agreement"), between Corning and Harris
Trust and Savings Bank, as fiscal agent, transfer agent, paying
agent and conversion agent (in any such capacity, the "Agent",
which term includes any successor Agent under the
Subordinated Debentures), to which reference is hereby made
for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of Corning, the Agent, the
holders of Senior Indebtedness and the holders of the
Subordinated Debentures and of the terms upon which the
Subordinated Debentures are, and are to be, delivered.  All
terms used in this Security which are defined in the Fiscal
Agency Agreement shall have the meanings assigned to them
in the Fiscal Agency Agreement.  This Subordinated Debenture
is one of the securities designated on the face hereof, limited
in aggregate principal amount to $__________.

The indebtedness evidenced by this Subordinated Debenture is to
the extent provided in the Fiscal Agency Agreement,
subordinate and subject in right of payment to the prior
payment in full of all Senior Indebtedness, and this Security is
issued subject to the provisions of the Fiscal Agency
Agreement with respect thereto.  Each holder of this Security,
by accepting the same, agrees to and shall be bound by such
provisions.

This Subordinated Debenture is subject to prepayment at any time
on or after _______________, 1998, as a whole or in part, at
the election of Corning, at the prepayment prices set forth in
the Fiscal Agency Agreement.

In the event of prepayment of this Subordinated Debenture in part
only, a new Subordinated Debenture for the unredeemed
portion hereof will be issued in the name of the holder hereof
upon the cancellation hereof.

If an Event of Default with respect to the Subordinated Debentures
shall occur and be continuing, the principal of the Subordinated
Debentures may be declared due and payable in the manner
and with the effect provided in the Fiscal Agency Agreement.

The Fiscal Agency Agreement permits, with certain exceptions as
therein provided, the amendment thereof and the modification
of the rights and obligations of Corning, Corning Delaware and
the rights of any other holders of the Subordinated Debentures
at any time by Corning, Corning Delaware and the Agent.

The Subordinated Debentures are convertible at any time on or
before the close of business on the Maturity Date at the option
of the holder into shares of Corning Common Stock at an
initial conversion price of $_____ per share of Corning
Common Stock, subject to adjustment as provided for in the
Fiscal Agency Agreement.   The holder of the Subordinated
Debentures will be entitled to receive the interest payable on
the Subordinated Debentures on the Interest Payment Date
notwithstanding the conversion thereof following the Business
Day immediately preceding such Interest Payment Date.  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 from a holder of the Preferred
Securities effecting a conversion thereof pursuant to its
conversion rights under the Limited Partnership Agreement. 
No fractional shares of Corning Common Stock will be issued
as a result of conversion, but in lieu thereof, in the sole
discretion of Corning, such fractional interest will be paid in
cash by Corning.

The Subordinated Debentures are exchangeable (in whole but not in
part) upon the occurrence of an Exchange Event at the
Exchange Price for Corning Series C Preferred Stock as
provided under the terms of the Fiscal Agency Agreement.

The Subordinated Debentures are issuable only in registered form
without coupons in denominations of $1,000 and any integral
multiple thereof.

                     Article II

                      Guarantee

      2.1   General. Corning irrevocably and unconditionally agrees
to pay in full to the Holders the Guarantee Payments, as and when due
(except to the extent paid by Corning Delaware), regardless of any
defense, right of set-off or counterclaim which Corning Delaware may
have or assert. This Guarantee is continuing, irrevocable, unconditional
and absolute. Corning's obligation to make a Guarantee Payment may
be satisfied by direct payment of the required amounts by Corning to
the Holders or by causing Corning Delaware to pay such amounts to
the Holders.

      2.2   Waiver of Certain Rights.  Corning hereby waives
notice of acceptance of this Guarantee and of any liability to which it
applies or may apply, presentment, demand for payment, protest, notice
of nonpayment, notice of dishonor, notice of redemption and all other
notices and demands.

      2.3   Obligations Not Affected.  The obligations, covenants,
agreements and duties of Corning under this Guarantee shall in no way
be affected or impaired by reason of the happening from time to time
of any of the following:

            (a)   the release or waiver, by operation of law or
      otherwise, of the performance or observance by Corning
      Delaware of any express or implied agreement, covenant, term
      or condition relating to the Preferred Securities to be performed
      or observed by Corning Delaware;

            (b)   the extension of time for the payment by
      Corning Delaware of all or any portion of the Dividends,
      distributions, Additional Dividends, Redemption Price,
      Liquidation Distribution or any other sums payable under the
      terms of the Preferred Securities or the extension of time for
      the performance of any other obligation under, arising out of,
      or in connection with, the Preferred Securities;

            (c)   any, failure, omission, delay or lack of
      diligence on the part of the Holders to enforce, assert or
      exercise any right, privilege, power or remedy conferred on the
      Holders pursuant to the terms of the Preferred Securities, or
      any action on the part of Corning Delaware granting indulgence
      or extension of any kind;

            (d)   the voluntary or involuntary liquidation,
      dissolution, sale of any collateral, receivership, insolvency,
      bankruptcy, assignment for the benefit of creditors,
      reorganization, arrangement, composition or readjustment of
      debt of, or other similar proceedings affecting, Corning
      Delaware or any of the assets of Corning Delaware;

            (e)   any invalidity of, or defect or deficiency in, any
      of the Preferred Securities; or

            (f)   the settlement or compromise of any obligation
      guaranteed hereby or hereby incurred.

There shall be no obligation of the Holders to give notice to, or obtain
any consent of, Corning with respect to the happening of any of the
foregoing.

      2.4   Holders May Proceed Directly Against Corning.  This
Guarantee is a guarantee of payment and not of collection. A Holder
may enforce this Guarantee 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. Subject to Section 2.5 hereof, all waivers
herein contained shall be without prejudice to the Holders' right at the
Holders' option to proceed against Corning Delaware, whether by
separate action or by joinder. Corning agrees that this Guarantee shall
not be discharged except by payment of the Guarantee Payments in full.

      2.5   Subrogation.  Corning shall be subrogated to all (if any)
rights of the Holders against Corning Delaware in respect of any
amounts paid to the Holders by Corning under this Guarantee and shall
have the right to waive payment of any amount of dividends or
distributions in respect of which payment has been made to the Holders
by Corning pursuant to Section 2.1 hereof; provided, however, that
Corning shall not (except to the extent required by mandatory
provisions of law) exercise any rights which it may acquire by way of
subrogation or any indemnity, reimbursement or other agreement, in all
cases as a result of a payment under this Guarantee, if, at the time of
any such payment, any amounts are due and unpaid under this
Guarantee. If any amount shall be paid to Corning in violation of the
preceding sentence, Corning agrees to pay over such amount to the
Holders.

      2.6   Independent Obligations.  Corning acknowledges that
its obligations hereunder are independent of the obligations of Corning
Delaware with respect to the Preferred Securities and that Corning shall
be liable as principal and sole debtor under this Guarantee to make
Guarantee Payments pursuant to the terms of this Guarantee
notwithstanding the occurrence of any event referred to in subsections
(a) through (f), inclusive, of Section 2.3 hereof.

      2.7   Termination.  This Guarantee shall terminate and be of
no further force and effect upon full payment of the Redemption Price
of all Preferred Securities, upon full payment of the amounts payable
to the Holders upon liquidation of Corning Delaware or upon the
conversion or exchange of all Subordinated Debentures into Corning
Common Stock or Corning Preferred Stock, as the case may be, and the
distribution of such stock to the Holders of the Preferred Securities then
outstanding; provided, however, that this Guarantee shall continue to be
effective or shall be reinstated, as the case may be, if at any time any
Holder of Preferred Securities must restore payment of any sums paid
under the Preferred Securities under this Guarantee for any reason
whatsoever.


                     Article III

            Certain Covenants of Corning

      3.1   Dividends and Other Payments. So long as any
Preferred Securities remain 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 class or series of
capital stock issued by Corning which ranks junior to the Corning
Preferred Stock in right of payment of dividends and amounts on
liquidation, dissolution and winding-up (other than as a result of a
reclassification of capital stock or the exchange or conversion of one
class or series of capital stock for another class or series of capital
stock) or make any guarantee payments with respect to the foregoing
(other than payments under this Guarantee or dividends or guarantee
payments to Corning), if at such time Corning shall be in default with
respect to its payment or other obligations hereunder or there shall have
occurred any event that, with the giving of notice or the lapse of time
or both, would constitute an Event of Default under the Subordinated
Debentures.  Corning shall take all actions necessary to ensure the
compliance of its subsidiaries with this Section 3.1.

      3.2   Certain Other Covenants.  Corning covenants that, so
long as any Preferred Securities remain outstanding: (a) to maintain
direct 100% ownership of the Partnership Interests and any other
interests in Corning Delaware other than the Preferred Securities; (b) to
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 a General Partner;
(c) not to voluntarily dissolve, wind up or liquidate itself or Corning
Delaware; (d) to remain the General Partner of Corning Delaware and
to timely perform all of its duties as General Partner (including the duty
to cause Corning Delaware to declare and pay dividends on the
Preferred Securities), unless a permitted successor General Partner is
appointed pursuant to the Limited Partnership Agreement; and (e)
subject to the terms of the Preferred Securities, to 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.


                     Article IV

                    Subordination

      4.1   Subordination.  Corning covenants and agrees that this
Guarantee constitutes an unsecured obligation of Corning ranking (i)
subordinate and junior in right of payment to all liabilities of Corning,
(ii) pari passu with the Series B Preferred Stock, par value $100 per
share, of Corning, 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 and the Series A
Preferred Stock, par value $100 per share, of Corning 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 or
amounts on liquidation, dissolution and winding-up to the Preferred
Securities.

                    Miscellaneous

      5.1   Third Party Beneficiaries.  All of Corning's obligations
under this Guarantee shall be directly enforceable by the Holders from
time to time of the Preferred Securities.  Each Holder of Preferred
Securities is an intended third-party beneficiary of this Guarantee.

      5.2   Successors and Assigns.  All guarantees and agreements
contained in this Guarantee shall bind the successors, assigns, receivers,
trustees and representatives of Corning and shall inure to the benefit of
the Holders. Except as permitted by Section 5.4, Corning shall not
assign its rights or delegate its obligations hereunder without the prior
approval of the Holders of not less than 66-2/3% of the aggregate
liquidation preference of all Preferred Securities then outstanding.

      5.3   Amendments.  Except with respect to any changes
which do not adversely affect the rights of Holders (in any of which
cases no vote will be required), this Guarantee may only be amended
by an instrument in writing signed by Corning with the prior approval
of the Holders of not less than 66-2/3% of the aggregate liquidation
preference of all Preferred Securities then outstanding.

      5.4   Merger or Consolidation.   Corning may, without the
consent of any Holders of Preferred Securities, merge or consolidate
with or into another entity or may permit another entity to merge or
consolidate with or into Corning, or may sell, transfer or lease all or
substantially all of Corning's assets to another entity, if (a) 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

entity organized under the laws of the United States or any state

NOW, THEREFORE, in consideration of the premises and the mutual covenants
and agreements herein contained and other good and valuable consideration,
receipt of which is hereby acknowledged, the parties hereto hereby agree as

2.      Securities Subject to this Agreement

        (a)      Registrable Securities.  The securities entitled to the
benefit of this Agreement (the "Registrable Securities") are all shares of
Corning Common Stock issued to MML, MMD, PLS, PPS and PPL Shareholders
pursuant to the Merger Agreement and including the shares held in escrow
under the Escrow Agreement as provided therein (including such shares
received as share dividends or shares issued on stock splits, mergers,
consolidations or other reorganizations), provided that, (subject to the
shareholder election provided in the next sentence) a share of Corning
Common Stock shall be a Registrable Security only for so long as such share
continues to be a Restricted Security.  A share of Corning Common Stock
ceases to be a "Restricted Security" when it (i) has been effectively
registered under the Securities Act and disposed of in accordance with the
Registration Statement covering it, or (ii) can be sold to the public
pursuant to Rule 144 (or any similar provisions then in force) under the
Securities Act; provided, however, that any Shareholder may elect to sell
pursuant to a Registration statement despite the availability of Rule 144,
and

        (b)      Holders of Registrable Securities.  A Person is deemed to
be a "holder" of Registrable Securities for purposes of this Agreement
whenever such Person owns Registrable Securities or has the right to acquire
such Registrable Securities, whether or not such acquisition has actually
been effected and disregarding any legal restrictions upon the exercise 

<PAGE>

of such right.  A Person is deemed to be the holder of all Registrable
Securities deposited by or on behalf of such Person with the Escrow Agent
under the Escrow Agreement.

3.      Registration of Registrable Securities

        (a)      Upon the written request of the MML Shareholder
Representative (on behalf of the former MML, MMD, PLS, PPS and PPL
Shareholders), Corning shall file, for the entire issue of Registrable
Securities, a "shelf" registration statement on any appropriate form
pursuant to Rule 415 (or similar rule that may be adopted by the SEC) under
the Securities Act, as promptly as practicable but in no event later than 5
days after such request or, if such 5th day is not a business day, the first
business day thereafter (the "Registration").  Corning shall use its best
efforts to cause such Registration to become effective as promptly as
possible after such filing and thereafter to keep such Registration
continuously effective, and to prevent the happening of any event of the
kind described in Section 4(c) (2)-(5) hereof that requires Corning to give
notice pursuant to the last paragraph of Section 4 hereof, for a period (the
"Applicable Period") of two years from the date on which the SEC declares
the Registration effective or such shorter period which will terminate when
all the Registrable Securities covered by the Registration have been sold
pursuant to such Registration or under Rule 144.

        (b)      The MML Shareholder Representative shall advise Corning in
such written request of the proposed method of distribution and the holders
who desire to sell their Registerable Securities pursuant to the
Registration Statement.

        (c)      Notwithstanding the foregoing, Corning may postpone the
filing of a registration statement (for a period not exceeding 90 days) if
its Board of Directors or the Executive Committee thereof in good faith
determines that the filing or the distribution of the Registerable
Securities will adversely interfere with a public offering by Corning or
with a financing, acquisition, corporate reorganization or similar corporate
transaction.

4.      Registration Procedures

        In connection with the registration of Registrable Securities
pursuant to Section 3 hereof, Corning will use its best efforts to 
effect such registration to permit the sale of such 

<PAGE>

Registrable Securities in accordance with the intended method or 
methods of distribution by the selling holders thereof and accordingly will:

        (a)      prepare and file with the SEC, as soon as practicable, a
Registration Statement or Registration Statements on any appropriate form
under the Securities Act, which form shall be available for the sale of the
Registrable Securities to be covered thereby in accordance with the intended
method or methods of distribution by the selling holders thereof and shall
include all financial statements required by the SEC to be filed therewith;
provided that before filing a Registration Statement or any amendments or
supplements thereto or Prospectus, including in each case documents
incorporated by reference, Corning will furnish to the holders of the
Registrable Securities covered by such Registration Statement and the
underwriters, if any, copies of all such documents at least five business
days prior to the day they are proposed to be filed, which documents will be
subject to the reasonable review of the MML and PPL Shareholder
Representative and underwriters, and Corning will not file any Registration
Statement or any amendment or supplement thereto or any Prospectus
(including in each case such documents as are incorporated by reference) to
which the MML or PPL Shareholder Representative or the underwriters, if any,
shall reasonably object;

        (b)      prepare and file with the SEC such amendments and
post-effective amendments to the Registration Statement as may be necessary
to keep the Registration Statement effective for the Applicable Period;
cause the Prospectus used in connection therewith to be supplemented by any
required Prospectus supplement, and as so supplemented to be filed pursuant
to Rule 424 under the Securities Act; and comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by
such Registration Statement during the Applicable Period in accordance with
the intended method or methods of distribution by the selling holders
thereof set forth in such Registration Statement as amended or supplement to
the Prospectus used in connection therewith;

        (c)      notify the selling holders of Registrable Securities and
the managing underwriters, if any, promptly, and (if requested by any such
Person) confirm such advice in writing, (1) when the Prospectus or any
Prospectus supplement or post-effective amendment has been filed, and, with
respect to the Registration Statement or any post-effective amendment, when
the same has become effective, (2) of any request by the SEC for 

<PAGE>

amendments or supplements to the Registration Statement or the Prospectus or 
for additional information, (3) of the issuance by the SEC of any stop order
suspending the effectiveness of the Registration Statement or the initiation
of any proceedings for that purpose, (4) of the receipt by Corning of any
notification with respect to the suspension of the qualification of the
Registrable Securities for sale in any jurisdiction or the initiation or
threatening of any proceedings for such purpose, and (5) of the happening of
any event which makes any statement made in the Registration Statement, the
Prospectus, any amendment or supplement thereto, or any document
incorporated therein by reference untrue or which requires the making of any
changes in the Registration Statement, the Prospectus or any document
incorporated therein by reference in order to make the statements therein
not misleading;

        (d)      upon the occurrence of any event contemplated by paragraph
(c)(5) above, prepare a supplement or post-effective amendment to the
Registration Statement or the related Prospectus or any document
incorporated therein by reference or file any other required document so
that, as thereafter delivered to the purchasers of the Registrable
Securities, the Prospectus will not contain any untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein not misleading;

        (e)      use its best efforts to obtain the withdrawal at the
earliest possible time of any order suspending or preventing the use of any
Prospectus or suspending the effectiveness of the Registration Statement or
any amendment or supplement thereto or suspending the qualification of any
Corning Common Stock included in such Registration Statement for sale in any
jurisdiction; 

        (f)      furnish each selling holder of Registrable Securities and
each managing underwriter, if any, without charge, at least one signed copy
of the Registration Statement and every post-effective amendment thereto,
including financial statements and schedules, all documents incorporated
therein by reference, and all exhibits (including those incorporated by
reference);

        (g)      deliver to each selling holder of Registrable Securities
and the underwriters, if any, without charge, as many copies of the
Prospectus (including each preliminary Prospectus) and any amendment or
supplement thereto as such Persons may reasonably request; consent to 

<PAGE>

the use of the Prospectus or any amendment or supplement thereto by each of 
the selling holders of Registrable Securities and the underwriters, if any, 
in connection with the offering and sale of the Registrable Securities 
covered by the Prospectus or any amendment or supplement thereto;

        (h)      prior to any public offering of Registrable Securities,
register or qualify or cooperate with the selling holders of Registrable
Securities, the underwriters, if any, and their respective counsel on a best
efforts basis to register or qualify such Registrable Securities for offer
and sale under the securities or blue sky laws of such jurisdictions as any
selling holder or underwriter reasonably requests in writing and do any and
all other acts or things necessary or advisable to enable the disposition in
such jurisdictions of the Registrable Securities covered by the Registration
Statement; provided that Corning will not be required to qualify generally
to do business in any jurisdiction where it is not then so qualified; 

        (i)      cooperate with the selling holders of Registrable
Securities and the managing underwriters, if any, to facilitate the timely
preparation and delivery of certificates representing Registrable Securities

and the underwriters, if any, in form, substance and scope as are

all financial and other records, pertinent corporate documents and
properties of Corning, and cause Corning's officers, directors and employees
to supply all information reasonably requested by any such representative,
underwriter, attorney or accountant in connection with such registration;
provided, that any records, information or documents that are designated by
Corning in writing as confidential shall be kept confidential by such
Persons unless disclosure of such records, information or documents is
required by court or administrative order to become publicly available or
becomes publicly available without the fault of such Person; 

        (m)      otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC, and make generally available to
its security holders earnings statements satisfying the provisions of
Section 11(a) of the Securities Act and Rule 158 thereunder, as soon as
practicable but in any event no later than 45 days after the end of any
12-month period (or 90 days, if such period is a fiscal year) (1) commencing
at the end of any fiscal quarter in which 

<PAGE>

Registrable Securities are sold to underwriters in a firm or best efforts 
Underwritten Offering, or (2) if not sold to underwriters in such an offering, 
beginning with the first month of Corning's first fiscal quarter commencing 
after the effective date of the Registration Statement, which statements shall 
cover said 12-month periods; and

        (n)      permit any selling holder of Registrable Securities which
holder believes he, she or it may be deemed to be an underwriter to require
the insertion in the Registration Statement, Prospectus, preliminary
prospectus, or any supplement or amendment thereto, any material which in
such holder's reasonable judgment should be inserted therein, provided that
such material be furnished under circumstances as shall cause it to be
subject to the indemnification provisions of Section 6(b) hereto and
provided that Corning shall not be required to insert any material that it
believes to contain any untrue statement of a material fact or any omission
of a material fact required to be stated therein or necessary to make the
statements therein not misleading.


        Corning may require such holder of Registrable Securities as to
which any registration is being effected to furnish to Corning such
information regarding the distribution of such securities as Corning may
from time to time reasonably request in writing.

        Each holder of Registrable Securities agrees by reason of its
acquisition and holding of such Registrable Securities that, upon receipt of
any notice from Corning of the happening of any event of the kind described
in Section 4(c) (2)-(5) hereof, such holder will forthwith discontinue
disposition of Registrable Securities until such holder's receipt of the
copies of the supplemented or amended Prospectus contemplated by Section
4(d) hereof, or until it is advised in writing (the "Advice") by Corning
that the use of the Prospectus may be resumed, and, if so directed by
Corning in writing, such holder will deliver to Corning (at Corning's
expense) all copies, other than permanent file copies then in such holder's
possession, of the Prospectus covering such Registrable Securities current
at the time of receipt of such notice.

5.      Registration Expenses

        (a)      Except as such expenses provided in Section 5(b) below
regarding the expenses incident to Corning's performance of or compliance
with Section 3 of this Agreement are to be borne by Corning, all expenses,
commissions, fees or discounts of underwriters, selling brokers, dealer
managers or similar securities industry professionals relating to the
distribution of the Registrable Securities and legal expenses of any Person
other than Corning will be borne by the holders of Registrable Securities,
regardless of whether the Registration Statement becomes effective.  

        (b)      All expenses incident to Corning's performance of or
compliance with this Agreement including without limitation all registration
and filing fees, fees with respect to listings or filings required to be
made with the New York Stock Exchange Inc., fees and expenses of compliance
with securities or blue sky laws, printing expenses, messenger, telephone
and delivery expenses, fees and disbursements of counsel for Corning and of
all independent certified public accountants of Corning (including the
expenses of any special audit and "cold comfort" letters required by or
incidental to such performance), and securities acts liability insurance if
Corning so desires, and reasonable fees and expenses of other Persons
retained by Corning in connection with the registration, will be borne by
Corning. 

6.      Indemnification

        (a)      Indemnification by Corning.  Corning agrees to indemnify
and hold harmless, to the full extent permitted by law, each holder of
Registrable Securities, against all losses, claims, damages, liabilities and
expenses (including reasonable attorney's fees and disbursements) caused by
(i) any violation of law by Corning in connection with or any breach by
Corning of its undertakings hereunder or (ii) any untrue or alleged untrue
statement of a material fact contained in any Registration Statement or any
amendment or supplement thereto, Prospectus, preliminary prospectus or
amendment or supplement thereto, or any omission or alleged omission of a
material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as the same are caused by
or contained in any information furnished in writing to Corning by such
holder expressly for use therein or by 

<PAGE>

such holder's failure to deliver a copy of the Registration Statement or 
Prospectus or any amendment or supplement thereto after Corning has furnished 
such holder with a sufficient number of copies of the same.  Corning will also 
indemnify underwriters, selling brokers, dealer-managers and similar 
securities industry professionals participating in the distribution, their 
officers and directors and each Person who controls such persons (within the 
meaning of the Securities Act) to the same extent as provided above with 
respect to the indemnification of the holders of Registrable Securities, if 
requested.

        (b)      Indemnification by Holders of Registrable Securities.  In
connection with the Registration, each holder of Registrable Securities will
furnish to Corning in writing such information and affidavits as Corning
reasonably requests in connection with any Registration Statement or
Prospectus and agrees to indemnify and hold harmless, to the full extent
permitted by law, Corning, its directors and officers and each Person who
controls Corning (within the meaning of the Securities Act) against any
losses, claims, damages, liabilities and expenses (including reasonable
attorney's fees and disbursements) resulting from any untrue statement of a
material fact contained in the Registration Statement, Prospectus,
preliminary prospectus, amendment or supplement thereto, or any omission of
a material fact required to be stated in the Registration Statement or
Prospectus or preliminary prospectus  necessary to make the statements
therein not misleading, to the extent, but only the extent, that such untrue
statement or omission is contained in any information or affidavit so
furnished in writing by such holder to Corning specifically for inclusion in
such Registration Statement, Prospectus, preliminary prospectus, amendment
or supplement thereto.  Corning shall be entitled to receive indemnities
from underwriters, selling brokers, dealer-managers and similar securities
industry professionals participating in the distribution, to the same extent
as provided above with respect to information so furnished in writing by
such Person specifically for the inclusion in any Prospectus or Registration
Statement.

        (c)       Conduct of Indemnification Proceedings.  Any Person
entitled to indemnification hereunder will (i) give prompt notice to the
indemnifying party of any claim with respect to which it seeks
indemnification and (ii) permit such indemnifying party to assume the
defense of such claims with counsel reasonably satisfactory to the
indemnified party, provided, however, that any Person entitled to
indemnification hereunder shall have the right to employ separate counsel
and to participate in the defense of such claims, but the fees 
        
<PAGE>

and expense of such counsel shall be at the expense of such Person unless (a) 
the indemnifying party has agreed to pay such fees or expenses, or (b) the
indemnifying party shall have failed to assume the defense of such claim and
employ counsel reasonably satisfactory to such Person, or (c) in the
reasonable judgment of any such Person, based upon advice of its counsel, a
conflict of interest may exist between such Person and the indemnifying
party  with respect to such claims (in which case, if the Person notifies
the indemnifying party in writing that such Person elects to employ separate
counsel at the expense of the indemnifying party, the indemnifying party
shall not have the right to assume the defense of such claim on behalf of
such Person).  If such defense is not assumed by the indemnifying party, the
indemnifying party will not be subject to any liability for any settlement
made by the indemnified party without its consent (but such consent will not
be unreasonably withheld).  No indemnifying party will be required to
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or
plaintiff to the indemnified party of a release from all liability in
respect to such claim or litigation.  An indemnifying party who is not
entitled to, or elects not to, assume the defense of a claim will not be
obligated to pay the fees and expenses of more than one counsel for all
parties indemnified by such indemnifying party with respect to such claim,
unless in the reasonable judgment of any indemnified party a conflict of
interest may exist between such indemnified party and any other of such
indemnified parties with respect to such claim, in which event the
indemnifying party shall be obligated to pay the fees and expenses of such
additional counsel or counsels.

        (d)      Contribution.  If for any reason the indemnification
provided for in Sections 6(a) and (b) is unavailable to an indemnified party
or insufficient to hold it harmless as contemplated by Sections 6(a) and
(b), then the indemnifying party shall contribute to the amount paid or
payable by the indemnified party as a result of such loss, claim, damage or
liability in such proportion as is appropriate to reflect the relative fault
of the indemnified party and the indemnifying party, as well as any other
relevant equitable considerations, provided that no selling holder shall be
required to contribute an amount greater than the dollar amount of the
proceeds received by such selling holder with respect to the sale of the
shares of Corning Common Stock giving rise to the claim.

<PAGE>

        (e)       Survival of Indemnification Obligation.  The
indemnifications provided for under this Agreement will remain in full force
and effect regardless of any investigation made by or on behalf of the
indemnified party or the controlling Person of each indemnified party and
will survive the transfer of the Registrable Securities.

7.      Rule 144.  In addition to its other obligations hereunder, Corning
shall file the reports required to be filed by it under the Securities Act
and the Exchange Act and the rules and regulations adopted by the SEC
thereunder (or, if Corning is not required to file such reports, it will,
upon the request of any holder of Registrable Securities made after the
Closing Date, make publicly available other information so long as necessary
to permit sales pursuant to Rule 144 under the Securities Act), and it will
take such further action as any holder of the Registrable Securities may
reasonably request, all to the extent required from time to time to enable
such holder to sell Corning Common Stock without registration under the
Securities Act within the limitation of the exemptions provided by (a) Rule
144 under the Securities Act, as such Rule may be amended from time to time,
or (b) any similar rule or regulation hereafter adopted by the SEC.  Upon
the request of any holder of Registrable Securities, Corning will deliver to
such holder a written statement as to whether it has complied with such
information and requirements. 

8.      Participation in Underwritten Registrations.  If any of the
Registrable Securities covered by the Registration Statement filed pursuant
to Section 3 above are to be sold in an Underwritten Offering, the
investment banker or investment bankers and manager or managers who will
administer the offering will be selected by the holders of a majority of the
outstanding shares of such Registrable Securities included in such offering,
provided that such investment bankers and managers must be reasonably
satisfactory to Corning.

        No Person may participate in any underwritten registration hereunder
unless such Person (a) agrees to sell such  Person's securities on the basis
provided in any underwriting arrangements approved by the Person entitled
hereunder to approve such arrangements and (b) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents required under the terms of such underwriting arrangements,
provided that no selling holder of Registered Securities in any underwritten
registration shall be required to make any representation or warranty to
Corning or the underwriters other than 

<PAGE>

representations and warranties regarding such holder and such holder's 
intended method of distribution. Nothing in this Section 8 shall be construed 
to create any additional rights regarding the registration of Registrable 
Securities in any Person otherwise than as set forth therein.

9.      Miscellaneous
        (a)      Amendments and Waivers.  The provisions of this Agreement,
including the provisions of this sentence, may not be waived, amended,
modified or supplemented except by a written instrument signed on behalf of
Corning and the MML, MMD, PLS, PPS and PPL Shareholder Representatives
making specific reference to this agreement and expressing the intention to
waive, amend, modify or supplement it.

                                                          Exhibit 5.1




                     June 28, 1994



To the Board of Directors
of Corning Incorporated and
Corning Incorporated,
as general partner of
Corning Delaware, L.P.

Dear Sirs: 

           As General Counsel of Corning Incorporated ("Corning")
and Corning Delaware, L.P. ("Corning Delaware"), I have participated in
the preparation of the Registration Statement on Form S-3 (No. 33-53821),
as amended (the "Registration Statement"), filed by Corning and Corning
Delaware today with the Securities and Exchange Commission with
respect to (i) the issuance and sale of Corning Delaware's Convertible
Monthly Income Preferred Securities (the "Preferred Securities"), (ii) the
shares of Corning Series C Convertible Preferred Stock, $100 par value
(the "Corning Series C Preferred Stock"), issuable upon certain events in
exchange for the Preferred Securities,  (iii) the shares of Corning Common
Stock, $.50 par value (the "Corning Common Stock"), issuable upon
conversion of the Preferred Securities and (iv) the guarantee (the
"Guarantee") of the Preferred Securities by Corning.

          In this capacity, I have examined signed copies of the
Registration Statement.  I have also examined the originals, or copies
identified to my satisfaction, of such corporate and partnership records of
Corning and Corning Delaware, respectively, such other agreements and
instruments, certificates of public officials and officers of Corning and
Corning Delaware and other persons, and such other documents as I have
deemed necessary as a basis for the opinions hereinafter expressed. 

          Based upon the foregoing and having regard for such legal
considerations that I deem relevant, I am of the opinion that:

          1.    Corning has been duly incorporated and is validly
existing under the laws of the State of New York and Corning Delaware
has been duly formed and is validly existing as a limited partnership under
the laws of the State of Delaware.

          2.    When delivered and paid for as contemplated by the
Registration Statement, the issuance of Preferred Securities in a public
offering pursuant to the Registration Statement will have been duly
authorized by all necessary partnership action on the part of Corning
Delaware and the Preferred Securities will be legally issued, fully paid and
non-assessable.

          3.    The shares of the Corning Series C Preferred Stock
issuable upon exchange of the Preferred Securities, when issued in
accordance with the terms of Preferred Securities and the Fiscal Agency
Agreement among Corning, Corning Delaware and Harris Trust and
Savings Bank (the "Fiscal Agency Agreement"), will have been duly
authorized by all necessary corporate action on the part of Corning and
will be legally issued, fully paid and non-assessable.

          4.    The shares of the Corning Common Stock issuable
upon conversion of the Preferred Securities, when issued in accordance

          Registration Statement on Form S-3
              (Registration No. 33-53821)     
Dear Sirs:

          We are acting as special federal income tax counsel for
Corning Delaware, L.P. ("Corning Delaware") and Corning Incorporated
("Corning") in connection with the registration of Convertible Monthly
Income Preferred Securities (the "Preferred Securities") pursuant to a
registration statement (No. 33-53821) on Form S-3 (the "Registration
Statement") filed by Corning and Corning Delaware with the Securities
and Exchange Commission.  In connection therewith, we have
participated in the preparation of, and have reviewed, the prospectus (the
"Prospectus") included in the Registration Statement.

          We have examined and relied upon the Registration
Statement and, in each case as filed with the Registration Statement, the
form of the Amended and Restated Agreement of Limited Partnership of
Corning Delaware, L.P., the form of the Fiscal Agency Agreement
among Corning Delaware and Corning and Harris Trust and Savings
Bank, as agent (the "Fiscal Agency Agreement"), the form of the
convertible subordinated debentures issued and sold by Corning to
Corning Delaware under the Fiscal Agency Agreement, and the
Guarantee Agreement of Corning (collectively, the "Operative
Documents").  

          Based on the foregoing and assuming that the Operative
Documents are executed and delivered in substantially the form we have
examined and that the transactions contemplated to occur under the
Operative Documents in fact occur in accordance with the terms thereof,
we hereby confirm that the discussion set forth in the Prospectus under
the caption "CERTAIN FEDERAL INCOME TAX CONSIDERATIONS" accurately 
describes, subject to the limitations stated therein, the material 
federal income tax considerations relevant to the purchase, ownership 
and disposition of the Preferred Securities.

          We hereby consent to the use of this letter as an exhibit
to the Registration Statement and to the use of our name under the
caption "CERTAIN FEDERAL INCOME TAX CONSIDERATIONS" in
the Prospectus.  

                                Very truly yours,
