                     DESCRIPTION OF CORNING CAPITAL STOCK 

General 
The following is a brief summary of certain provisions of the Restated 
Certificate of Incorporation of Corning (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 Corning Common Stock. As of September 22, 1994, 
221,320,154 shares of Corning Common Stock were outstanding. The rights of 
holders of Corning Common Stock are governed by the Restated Certificate, 
Corning'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 (as defined 
below) that may be outstanding, voting power is vested in Corning Common 
Stock, each share having one vote. 

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

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

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

MIPS Offering 
On July 21, 1994 Corning and Corning Delaware, L.P., a Delaware special 
purpose limited partnership in which Corning is the sole general partner, 
completed the offering (the "MIPS Offering") of $373.8 million aggregate 
principal amount of 6% Convertible Monthly Income Preferred Securities (the 
"Preferred Securities") of Corning Delaware. 

Dividends on the Preferred Securities will be cumulative and will be payable 
monthly at an annual rate of six percent. In certain circumstances, holders 
of the Preferred Securities, voting as a class or by written consent, may 
cause the exchange of the Preferred Securities for shares of Corning's Series 
C Preferred Stock (herein defined), at a rate of one share of Series C 
Preferred Stock for every two Preferred Securities. Each Preferred Security 
is convertible at the option of the holder into Corning Common Stock at the 
rate of 1.2821 shares of Corning Common Stock for each Preferred Security 
(equivalent to a conversion price of $39.00 per share of Corning Common 
Stock), subject to adjustment in certain circumstances. From time to time 
after four years from the date of issuance, the Preferred Securities will be 
redeemable, at the option of Corning Delaware, in whole or in part, for cash 
at stated redemption prices. 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). Holders of the 
Preferred Securities do not have any voting rights, except in certain 
instances of default. 

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 Corning Board 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 Corning 
Board has designated 600,000 shares of Series Preferred Stock as Series A 
Preferred Stock, 316,822 shares of Series Preferred Stock as Series B 
Preferred Stock (the "Series B Preferred Stock"), and an as yet unspecified 
number of shares of Series Preferred Stock as Series C 6% Cumulative 
Convertible Preferred Stock (the "Series C Preferred Stock"). No other class 
of Series Preferred Stock has been designated by the Corning Board. 

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. Corning has regularly 
paid dividends on the Series B Preferred Stock. No dividends may be paid or 
declared on the Series A Preferred Stock or Corning 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 Corning Common Stock and not as a separate class, on all matters 
submitted to holders of Corning 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 Corning, holders of Series B 
Preferred Stock shall be entitled to receive a distri- 

                                      7

<PAGE>


bution in the amount of $100 per share, plus accrued and unpaid dividends, 
before any distribution on Corning Common Stock or Series A Preferred Stock. 

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

<TABLE>
<CAPTION>
 During the Twelve- 
Month Period               Price Per 
Beginning October 1,         Share 
<S>                         <C>
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 $100.00 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. 

Corning, at its option, may make payment of the redemption price required 
upon redemption of shares of Series B Preferred Stock in cash or in Corning 
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 Corning Common Stock at a conversion price of $25.00 per share 
of Corning 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 Corning Common Stock for each share of Series B 
Preferred Stock so converted, subject to certain adjustments to prevent 
dilution. 

Series C Preferred Stock 

In certain circumstances, the holders of a majority of the aggregate 
liquidation preference of the Preferred Securities then outstanding, voting 
as a class or by written consent, may cause the exchange of the Preferred 
Securities for Series C Preferred Stock at a rate of one share of Series C 
Preferred Stock for every two Preferred Securities. 

The terms of the Series C Preferred Stock are substantially similar to those 
of the Preferred Securities except that, among other differences, (i) in 
certain events of default, the number of directors of Corning shall be 
increased by two persons and the holders of the Series C Preferred Stock will 
be entitled to elect the persons to fill such positions and (ii) the Series C 
Preferred Stock will not be subject to mandatory redemption. 

The Series C Preferred Stock ranks senior to the Corning Common Stock and the 
Series A Preferred Stock with respect to the payment of dividends and amounts 
on liquidation, dissolution and winding-up. In the event of a voluntary or 
involuntary bankruptcy, liquidation, dissolution or winding-up of Corning, 
the holders of 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 Series C Preferred Stock, $100.00 per share 
in cash plus accumulated and unpaid dividends (whether or not earned or 
declared) to the date of final distribution to such holders. 

Preferred Share Purchase Rights 
Attached to each share of Corning Common Stock is one Right, which entitles 
the registered holder to purchase from Corning 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 Corning. 

The Rights represented by the certificates for Corning Common Stock are not 
exercisable, and are not transferable apart from the Corning Common Stock 
until the earlier of (i) ten days following the public announcement by 
Corning or an Acquiring Person (as defined below) that a person or group has 
acquired beneficial ownership of 20% or more of the Corning Common Stock (an 
"Acquiring Person") or (ii) ten busi- 

                                      8 


<PAGE>
<PAGE>
ness days (or such later date as the Corning Board 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 
Corning 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 Corning Common Stock as of such date. The Rights could 
then begin trading separately from Corning 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, Corning 
Common Stock having a value equal to two times the Exercise Price of the 
Right. In the event that Corning is acquired in a merger, consolidation, or 
other business combination transaction or more than 50% of Corning'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 $0.125 per Right at 
any time on or prior to any person or group becoming an Acquiring Person. The 
right to exercise the Rights terminates at the time that the Corning Board 
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, Corning 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 Corning, 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 Corning on 
terms not approved by the Corning Board, 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 Corning Board since the Rights may be redeemed by Corning at $.125 per 
Right prior to the fifteenth day after the acquisition by a person or group 
of beneficial ownership of 20% or more of the Corning 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 Corning'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 $10.00 per share, but will be 
entitled to an aggregate dividend of 100 times the dividend declared per 
share of Corning 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 Corning 
Common Stock. Each share of Series A Preferred Stock will have 100 votes, 
voting together with the Corning Common Stock. In the event of any merger, 
consolidation or other transaction in which Corning 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 Corning 
Com- 

                                      9

mon 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 Corning 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 Corning 
and the Rights Agent, as amended by the Amended Rights Agreement, dated as of 
October 4, 1989, which has been previously filed with the Commission. 

Corning's Fair Price Amendment 
In 1985 Corning'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 Corning (other than the Series C Preferred 
Stock) entitled to vote generally in the election of directors (the "Corning 
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 Corning Voting Stock unless the proposed amendment or repeal or the 
adoption of the inconsistent provisions were approved by two-thirds of the 
entire Corning Board and a majority of the Continuing Directors. 

Certain Other Provisions of Corning's 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 Corning or to commence a 
proxy contest or other takeover-related action. Corning has classified its 
Board such that one-third of the Corning Board is elected each year to 
three-year terms of office. In addition, holders of Corning 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 Corning 
Common Stock outstanding. These provisions, together with provisions 
concerning the size of the Corning Board and requiring that premature 
vacancies on the Corning Board be filled only by a majority of the entire 
Corning Board, may not be amended, altered or repealed, nor may Corning adopt 
any provisions inconsistent therewith, without the affirmative vote of at 
least 80% of the Corning Voting Stock of Corning or the approval of two- 
thirds of the entire Corning Board. 

Corning'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 Corning 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 Corning By-Laws do 
not provide that a meeting of the Corning Board may be called by 
stockholders. 

The Restated Certificate provides that no director will be liable to Corning 
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 Corning 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 Corning Common Stock, or to deter 
attempts to remove the Corning Board and management of Corning, even though 
some or a majority of the holders of Corning Common Stock may believe such 
actions to be beneficial. 

                             PLAN OF DISTRIBUTION 

The Shares are being sold by the Selling Stockholders for their own accounts. 
Except for the following limited circumstance, Corning will receive none of 
the proceeds from the offering. For the purpose of securing the 
indemnification obligations of the Selling Stockholders to the Company set 
forth in the Agreement, 10% of the Shares are and will be held in escrow 
until no later than June 7, 1995. 

The Shares may be sold from time to time directly by the Selling 
Stockholders. In the alternative, the distribution of the Shares by the 
Selling Stockholders may be effected from time to time by underwriters 

                                      10 


<PAGE>
<PAGE>


who may be selected by the Selling Stockholders and one or more other 
broker-dealers, in one or more transactions (which may involve crosses and 
block transactions) on the New York Stock Exchange or other exchanges, in 
special offerings, exchange distributions or secondary distributions pursuant 
to and in accordance with the rules of such exchanges, in the 
over-the-counter market, in negotiated transactions or otherwise, at market 
prices prevailing at time of sale, at prices related to such prevailing 
market prices or at negotiated prices. In the event that such underwriters or 
broker-dealers agree to sell the Shares, they may do so by purchasing the 
Shares as principals or by selling the Shares as agents for the Selling 
Stockholders. Underwriters selected by the Selling Stockholders, and any such 
other broker-dealer, may receive compensation from the Selling Stockholders 
in the form of underwriting discounts, concessions or commissions and may 
receive commissions from purchasers of the Shares for who they may act as 
agents. If underwriters who may be selected by the Selling Stockholders, and 
any such other broker- dealer, purchase the Shares as principals, they may 
effect resales of the Shares from time to time to or through other 
broker-dealers, and such other broker-dealers may receive compensation in the 
form of concessions or commissions from the Selling Stockholders or 
purchasers of Shares for whom they may act as agents. Corning has agreed to 
indemnify the Selling Stockholders, against certain liabilities, including 
liabilities under the Securities Act, and to pay the expenses of registering 
the Shares for offering and sale to the public under the Securities Act. 

Information as to whether underwriters who may be selected by the Selling 
Stockholders, or any other broker-dealer, is acting as principal or agent for 
the Selling Stockholders, the compensation to be received by underwriters who 
may be selected by the Selling Stockholders, or any broker-dealer, acting as 
principal or agent for the Selling Stockholders and the compensation to be 
received by other broker-dealers, in the event the compensation of such other 
broker-dealers is in excess of usual and customary commissions, will be 
disclosed in a prospectus filed pursuant to Rule 424(b) under the Securities 
Act, or in a supplement to this prospectus filed pursuant to Rule 424(c) of 
the Securities Act to the extent required. 

The Company has agreed with the Selling Stockholders to maintain the 
continuous effectiveness of the Registration Statement (of which this 
Prospectus is a part) during the period commencing on the date the 
Registration Statement is declared effective and ending on the second 
anniversary of the effective date of the Registration Statement or such 
shorter period which will terminate when all the Shares have been sold 
pursuant to the Registration Statement.

Item 15. Indemnification of Directors and Officers. 
Under the NYBCL, a corporation may indemnify its directors and officers made, 
or threatened to be made, a party to any action or proceeding, except for 
stockholder derivative suits, if such director or officer acted in good 
faith, for a purpose which he or she reasonably believed to be in or, in the 
case of service to another corporation or enterprise, not opposed to, the 
best interests of the corporation, and, in criminal proceedings, had no 
reasonable cause to believe his or her conduct was unlawful. In the case of 
stockholder derivative suits, the corporation may indemnify a director or 
officer if he or she acted in good faith for a purpose which he or she 
reasonably believed to be in or, in the case of service to another 
corporation or enterprise, not opposed to the best interests of the 
corporation, except that no indemnification may be made in respect of (i) a 
threatened action, or a pending action which is settled or otherwise disposed 
of, or (ii) any claim, issue or matter as to which such person has been 
adjudged to be liable to the corporation, unless and only to the extent that 
the court in which the action was brought, or, if no action was brought, any 
court of competent jurisdiction, determines upon application that, in view of 
all the circumstances of the case, the person is fairly and reasonably 
entitled to indemnity for such portion of the settlement amount and expenses 
as the court deems proper. 

Any person who has been successful on the merits or otherwise in the defense 
of a civil or criminal action or proceeding will be entitled to 
indemnification. Except as provided in the preceding sentence, unless ordered 
by a court pursuant to the NYBCL, any indemnification under the NYBCL 
pursuant to the above paragraph may be made only if authorized in the 
specific case and after a finding that the director or officer met the 
requisite standard of conduct by (i) the disinterested directors if a quorum 
is available, (ii) the board upon the written opinion of independent legal 
counsel or (iii) the stockholders. 

The indemnification described above under the NYBCL is not exclusive of other 
indemnification rights to which a director or officer may be entitled, 
whether contained in the certificate of incorporation or by-laws or when 
authorized by (i) such certificate of incorporation or by-laws, (ii) a 
resolution of stockholders, (iii) a resolution of directors or (iv) an 
agreement providing for such indemnification, provided that no 
indemnification may be made to or on behalf of any director or officer if a 
judgment or other final adjudication adverse to the director or officer 
establishes that his or her acts were committed in bad faith or were the 
result of active and deliberate dishonesty and were material to the cause of 
action so adjudicated, or that he or she personally gained in fact a 
financial profit or other advantage to which he or she was not legally 
entitled. 

The foregoing statement is qualified in its entirety by reference to Sections 
715, 717 and 721 through 725 of the NYBCL. 

Article VIII of the registrant's By-Laws provides that the registrant shall 
indemnify each director and officer against all costs and expenses actually 
and reasonably incurred by him in connection with the defense of any claim, 
action, suit or proceeding against him by reason of his being or having been 
a director or officer of the registrant to the full extent permitted by, and 
consistent with, the NYBCL. 

The directors and officers of the registrant are covered by insurance 
policies indemnifying them against certain liabilities, including certain 
liabilities arising under the Securities Act, which might be incurred by them 
in such capacities.

Item 17. Undertakings. 
The Company hereby undertakes (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 1933; (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 thereof) 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 
the Company's annual report pursuant to Section 13(a) or Section 15(d) of the 
Securities Exchange Act of 1934 (and, where applicable, each filing of an 
employee benefit plan's annual report pursuant to 

                                      14

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. 

Insofar as indemnification for liabilities arising under the Securities Act 
of 1933 may be permitted to directors, officers and controlling persons of 
the Company pursuant to the foregoing provisions, or otherwise, the Company 
has 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 the 
Company of expenses incurred or paid by a director, officer or controlling 
person of the Company 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, the Company 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.

their operations and changes in their financial position for the periods then 
ended, in conformity with generally accepted accounting principles applied on

pending, or to the knowledge of Corning or any MergerSub threatened, or as to 
which Corning, any subsidiary of Corning or any MergerSub has received any 
notice, claim or assertion, which involves a potential cost or liability to 
Corning or any subsidiary of Corning which would, if adversely determined, 
singly or in the aggregate, materially and adversely affect the financial 
condition, result of operations, business or prospects of Corning and its 
subsidiaries considered as a whole. Neither Corning nor any subsidiary of 
Corning is in default with respect to any order, writ, injunction or decree 
of any court or before any federal, state, municipal or other governmental 
department, commission, board, bureau, agency or instrumentality, domestic or

the Merger, to continue the business that MML, MMD, PLS, PPS and PPL, 
respectively, currently conducts and (ii) not to dispose of the shares of or 
liquidate MML, MMD, PLS, PPS or PPL, except that Corning may, subsequent to

subsidiaries considered as a whole or any other event, condition or state of

(a) Indemnification by MML Group Shareholders. (i) Subject to Section 8.4 
above, the terms of the Escrow Agreement and the limitations set forth below, 
the members of the MML Group, jointly and severally, shall indemnify Corning 
and the MergerSubs against losses, including any and all costs, expenses, 
liabilities, judgments, assessments or penalties and reasonable attorneys' 
fees and disbursements relating thereto ("Losses"), which Losses are suffered 
or incurred by Corning or the MergerSubs resulting from or arising out of (A)

warranties or covenants of the MML Group or any member thereof, contained in 
this Agreement or any Schedule or certificate delivered to Corning pursuant 
to this Agreement, (B) any professional liability claims against MML, MMD, 
PLS, PPS, PPL or its Subsidiaries not covered by insurance which arose out of 
operations of MML, MMD, PLS, PPS, PPL and their Subsidiaries prior to the

Closing, provided that if Corning shall not maintain professional liability 
insurance coverage in the same policy amounts (including retentions) as 
heretofore maintained by MML, MMD, PLS, PPS and PPL, then the MML Group 
Shareholders' liability hereunder to Corning for Losses incurred on account 
of such claims shall be limited to those Losses that would have been incurred 
had such insurance been maintained, and provided further that the MML Group 
shareholders shall not be liable to Corning for any Loss caused by an error 
or omission of Corning or any affiliate of Corning which is an affiliate of 
Corning at the time of such error or omission, and (C) Losses suffered or 
incurred by Corning or the MergerSubs resulting from or arising out of claims 
by third parties of a breach of any provision any contract set forth on Part

Agreement shall be limited to the Escrow Fund under the Escrow Agreement, and

covenant or any indemnity hereunder or pursuant hereto (collectively,

claim asserted by Corning shall be for at least $25,000. 

(b) Indemnification by Corning. Subject to Section 8.4 above, Corning shall 
indemnify the MML Group Shareholders against losses (including any and all 
costs, expenses, liabilities, judgments, assessments or penalties and all 
reasonable attorneys' fees and disbursements relating thereto) suffered or 
incurred by the MML Group Shareholders resulting from or arising out of the 
substantial inaccuracy or material breach of any representations, warranties

or certificate delivered to the MML Group pursuant to this Agreement.

the parties which are not resolved by means of direct negotiations between 
them shall be finally settled by arbitration in accordance with this Section 
8.5(c). The arbitration shall be held in or around Baltimore, Maryland and 
shall be conducted in accordance with the commercial arbitration rules of the 
American Arbitration Association (AAA) by one arbitrator, appointed by 
consent of Corning and the MML Group representative which consent shall not 
be unreasonably withheld or delayed. If the parties cannot agree upon an 
arbitrator, either may apply to the AAA to appoint one. The arbitrator shall 
resolve the dispute within 60 days after the dispute is submitted to him. Any 
decision by the arbitrator shall be binding upon the parties and may be 
entered as a final judgment in any court having jurisdiction. The cost of any 
arbitration proceeding shall be borne by the parties as the arbitrator shall 
determine if the parties have not otherwise agreed. The arbitrator shall 
render his final decision in writing to the parties, which decision shall 
explain the reasons therefor. 

(d) Third Party Claims. If any claim is made or an action is brought against 
Corning for which indemnification from the MML Group is available to Corning 
under this Agreement, Corning shall notify the MML Group promptly in writing 
upon the receipt of notice of such claim or summons, as the case may be, and 
the MML Group may at its option thereafter assume the defense thereof with 
counsel reasonably acceptable to Corning which fees and expenses of defense 
shall be charged to and paid out of the Escrow Fund, provided that Corning 
may continue to participate in (but not control) the defense and disposition 
of such claim or action at its expense. Corning shall cooperate with the MML 
Group in the defense of such claim or action, and no settlement of such claim 
or action which does not involve a total release of Corning and its 
Subsidiaries from such claim or action shall be made by the MML Group without 
Corning's approval, which shall not be unreasonably withheld.

member of the MML Group which is an S corporation (within the meaning of 
Section 1361 of the Internal Revenue Code) or a partnership attributable to a 
taxable period ending on or before the Closing Date and arising solely from 
the reallocation of income or deductions between such entity member and 
another entity member of the MML Group which is not an S corporation or a 
partnership, shall be for the credit of Corning, but only to the extent that 
such refund (i) is not attributable to a timing difference that will decrease 
the taxes of an entity member of the MML Group in the same year or a later 
year, or (ii) is not offset by a corresponding increase in the taxes of an 
MML Group Shareholder of another member of the MML Group, which is an S 
corporation or a partnership. Any refund payable to Corning pursuant to this 
Section, shall be paid promptly by the respective MML Group Shareholders. 

(b)  Any deficiencies or assessments for additional income taxes against an 
MML Group Shareholder attributable to an entity member of the MML Group which 
is an S corporation or a partnership, for a taxable period ending on or 
before the Closing Date and arising solely from (i) the reallocation of 
income or deductions between such entity member and another entity member of 
the MML Group which is not an S corporation or (ii) the capitalization of a 
previously deducted item by an entity member of the MML Group, which is an S 
corporation or a partnership, shall be the responsibility of Corning, except 
to the extent such deficiency or assessment (A) is not attributable to a 
timing difference that will decrease the taxes of another entity member of 
the MML Group in the same year or in a later year or (B) is offset by 

                                      42 


<PAGE>
<PAGE>


a corresponding decrease in the taxes of an MML Group Shareholder of another 
member of the MML Group which is an S corporation or a partnership. In the 
case of such a deficiency or assessment, Corning shall distribute to the 
appropriate MML Group Shareholders the shares due them, determined by 
dividing the amount of such tax deficiencies or assessments (including any 
interest thereon, if any) by the Value of a Share of Common Stock as defined 
in Section 2.3(b) of the Escrow Agreement. 

(c) Corning, on the one hand, and the MML Group Shareholders, on the other 
hand, agree to give prompt notice to each other of any proposed adjustment to 
taxes for periods ending on or prior to the Closing Date or any pre-Closing 
partial period. Corning and the MML Group Shareholders shall cooperate with 
each other in the conduct of any audit or other proceedings involving the 
acquired corporations, and each may participate at its own expense, provided 
that the applicable MML Group Shareholders shall have the right to control 
the conduct of any such audit or proceeding for which they agree that any 
resultant taxes are covered by the indemnity set forth in this Agreement. 
Notwithstanding the foregoing, the MML Group Shareholders may not settle or 
otherwise resolve any claim, suit, or proceeding without the consent of 
Corning during the period that the indemnity in this Section 8.14 remains 
outstanding, such consent not to be unreasonably withheld.

Exhibit 5.01 

September 29, 1994 

To the Board of Directors of Corning
Incorporated 

Dear Sirs: 


As General Counsel for Corning Incorporated (the "Company"), I have
participated in the preparation of a Registration Statement on Form S-3 (the
"Registration Statement") being filed today with the Se curities and Exchange
Commission with respect to 4,451,197 shares of the Company's Common Stock, $.50
par value (the "Common Stock"), issued on June 7, 1994 to the shareholders of
Maryland Medical Laboratory, Inc., a Maryland corporation; Maryland Medical
Data, Inc., a Maryland corporation; P harmaceutical Laboratory Services, Inc., a
Maryland corporation; Passen Professional Service, P.A., a Maryland professional
corporation and Podiatric Pathology Laboratories, Inc., a Maryland corporation
(collectively the "MML Group") pursuant to the terms of the Agreement and Plans
of Merger dated as May 3, 1994 between the Company, the MML Group and the
shareholders of the MML Group (the "Agreement").

In this capacity, I have examined signed copies of the Registration
Statement to be filed with the Commission today. I have also examined the
originals, or copies identified to my satisfaction, of such corporate records of
the Company, such other agreements and instruments, certificates of public
officials, officers of the Company and other persons, and such other documents
as I have deemed necessary as a basis for the opinions hereinafter expressed.
Based upon the for egoing and having regard for such legal  considerations  
that I deem  relevant,  I am of the opinion  that: 

1. The Company has been duly incorporated and is validly existing under the 
laws of the State of New York; 

2. The execution and delivery on behalf of the Company of the Agreement has
been duly authorized by all proper corporate proceedings of the Company and
constitutes a legal, valid and binding instrument of the Company; and

3. The 4,451,197 shares of Common Stock of the Company issued pursuant to
the terms of the Agreement are validly issued, fully paid and nonassessable. 

I hereby consent to the use of this opinion as an exhibit to the
Registration Statement and to the use of my name in "Legal Opinions" in the
related prospectus.


Very truly yours,

/s/ William C. Ughetta
