                     QUESTIONS AND ANSWERS ABOUT THE MERGER

         The Board of Directors of NetOptix Corporation has unanimously approved
a merger in which Corning Incorporated will acquire NetOptix. The following
questions and answers provide an overview of certain important facts in
connection with the proposed transaction. You should read this entire proxy
statement/prospectus and the other materials referred to before determining how
to vote at the special meeting of NetOptix stockholders on June __, 2000.

Q:   WHY ARE CORNING AND NETOPTIX PROPOSING TO MERGE?

A:   The combination of the two companies and their complementary businesses
     serving the telecommunications industry will create a company we believe is
     uniquely qualified to capitalize on new opportunities domestically and
     around the world.

Q:   WHAT WILL HAPPEN IN THE MERGER?

A:   NetOptix will become a direct subsidiary of Corning by the merger of CI
     Subsidiary, Inc., a wholly-owned subsidiary of Corning,
     into NetOptix.

Q:   WHAT WILL NETOPTIX STOCKHOLDERS RECEIVE?

A:   NetOptix stockholders will be entitled to receive 0.90 of a share of
     Corning common stock in exchange for each of their shares of NetOptix
     common stock. Corning will not issue fractional shares. Instead, you will
     receive a cash payment equal to the market value of the fractional share.

     For example:

     If you currently own 1,000 shares of NetOptix common stock, then after the
     merger you will be entitled to receive 900 shares of Corning common stock.

     If you currently own 175 shares of NetOptix common stock, then after the
     merger you will be entitled to receive 157 shares of Corning common stock
     and a check for the market value of the .50 fractional share of Corning
     common stock.

     On _________, 2000 the closing price per share of Corning common stock on
     the NYSE was $_____.__ and of NetOptix common stock on the NASDAQ was
     $____.__.

Q:   AS A STOCKHOLDER, HOW WILL THE MERGER AFFECT ME?

     A: After the merger, you will own shares of Corning, a company that will
     then own NetOptix as well as Corning's ongoing businesses. Holders of
     NetOptix common stock will receive Corning common stock in exchange for
     their NetOptix common stock.

Q:   WHAT AM I BEING ASKED TO VOTE UPON?

A:   You are being asked to vote to approve the merger and to adopt the merger
     agreement.

Q:   WHAT DO I NEED TO DO NOW?

     A: After carefully reading and considering the information contained in
     this proxy statement/prospectus, indicate in the enclosed proxy card how
     you want to vote, and sign and submit it in the enclosed return envelope as
     soon as possible so that your shares may be represented at the special
     meeting. All proxy cards received prior to the special meeting will be
     voted at the special meeting. If you sign and send in your proxy and do not
     indicate how you want to vote, we will count your proxy as a vote in favor
     of the merger and for adoption of the merger agreement. If you do not vote,
     or if you abstain, it will have the effect of a vote against the merger.

     THE NETOPTIX BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS VOTING IN FAVOR OF
     THE PROPOSED MERGER.

Q:   CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY?

A:   Yes. You can change your vote at any time before your proxy is voted at the
     special meeting. You can do this in one of three ways. First, you can send
     a written notice stating that you would like to revoke your proxy. Second,
     you can complete and submit a new proxy. If you choose either of these two
     methods, you must submit your notice of revocation or your new proxy to the
     Secretary of NetOptix at the address set forth below. Third, you can attend
     the special meeting and vote in person.

Q:   IF MY NETOPTIX SHARES ARE HELD IN THE NAME OF MY BROKER, WILL MY BROKER
     VOTE MY SHARES FOR ME?

A:   Your broker will vote your NetOptix shares only if you provide instructions
     on how to vote. You should instruct your broker to vote your shares
     according to your directions. Without instructions, your shares will not be
     voted by your broker which will have the effect of a vote against the
     merger. You should follow the directions provided by your broker.

Q:   SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A:   No. Corning has appointed Harris Trust & Savings Bank as exchange agent to
     coordinate the exchange of your shares of NetOptix common stock for shares
     of Corning common stock. After the merger is completed, you will receive
     written instructions for exchanging your stock certificates. Please do not
     send in your stock certificates with your proxy.

Q:   WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A:   We are working to complete the merger as quickly as possible. In addition
     to NetOptix's shareholder approval, we must also obtain regulatory
     approvals and satisfy other customary requirements set forth in the merger
     agreement. We hope to complete the merger shortly after the special
     meeting.

Q:   WHAT ARE MY TAX CONSEQUENCES AS A RESULT OF THE MERGER?

A.   The exchange of NetOptix common stock for Corning common stock will be tax
     free for federal income tax purposes. However, you will have to pay taxes
     on any cash received for fractional shares. We recommend that you read the
     more detailed explanation of the U.S. federal income tax consequences on
     pages __ through ___ carefully.

Q:   WHO CAN HELP ANSWER MY QUESTIONS?

A:   If you have any questions about the merger or if you need additional copies
     of this proxy statement/prospectus or the enclosed proxy, you should
     contact:

CI SUBSIDIARY, INC.
c/o Corning Incorporated
One Riverfront Plaza
Corning, New York  14831

         CI Subsidiary, Inc. is a wholly-owned subsidiary of Corning, formed
under the laws of the State of Delaware solely for purposes of acting as a party
to the merger. CI Subsidiary, Inc. will merge with and into NetOptix and
NetOptix will be the surviving corporation.

REASONS FOR THE MERGER (PAGES __ THROUGH __)

         The NetOptix board of directors believes that the merger is in the best
interests of NetOptix and its stockholders. In reaching its decision to approve
the merger the NetOptix board of directors considered a number of factors,
including the following:

- -    the effect of the merger on implementing and accelerating NetOptix's basic
     long-term growth strategy in light of the current economic, financial and
     business environment, the limited size of NetOptix, its limited financial
     resources and customer base and its dependence on a single line of
     business;

- -    NetOptix's financial condition, results of operations, business and
     prospects compared to those of the combined companies the price and other
     terms of the merger agreement, as well as other information concerning the
     merger, including the structure of the merger;

- -    Corning's strong research and development capabilities, and its existing
     commitment to the optical filter market, which would significantly
     strengthen NetOptix's existing technology and product development efforts;
     and Corning's financial resources, customer relationships and commitment to
     drive NetOptix's business forward;

- -    the alternatives available to NetOptix in lieu of the transaction,
     including acquiring other companies or seeking joint venture partners and
     remaining as a stand-alone entity;

- -    the benefits of the merger, including its view that the combined company
     might be able to capitalize on operational and competitive elements that
     may not be available otherwise to NetOptix on a stand-alone basis;

- -    the opportunity for you to become holders of Corning common stock, which
     the NetOptix board of directors believed would perform at least as well as
     NetOptix common stock over the long term and would have greater liquidity
     and lower volatility than NetOptix common stock;

                                      -2-
<PAGE>

- -     the opinion of Salomon Smith Barney Inc. that as of date of that opinion
      the exchange ratio pursuant to the merger agreement was fair from a
      financial point of view to holders of NetOptix common stock;

- -    Corning's reputation and policies with respect to its employees, and the
     impact on NetOptix's employees of becoming employees of Corning;

- -    economies of scale because the telecommunications industry, particularly
     the fiberoptics transmission materials industry, is currently characterized
     by intense competition and large-scale consolidation; and

- -    the effect on NetOptix stockholders of NetOptix continuing as a stand-alone
     entity compared to the effect of NetOptix combining with Corning, in light
     of the factors summarized above.

              Executive Officer of NetOptix as well as its principal
              stockholder, will be amended to remove conditions to the vesting

              aggregate of 150,000 shares of NetOptix common stock granted to

              purposes.

              aggregate of 381,450 shares of NetOptix common stock granted to

              executive officers) in order to immediately vest these options if

                  agreement;

              -   granted Corning an irrevocable proxy to vote his or its shares

                                      -4-
<PAGE>


              -   agreed not to solicit any proposal from any third person which

              which will, as a result of the merger, and unless exercised prior
              thereto, be converted into a warrant to acquire 900,000 shares of
              Corning common stock at an exercise price equal to $1.66 ($1.50
              divided by the exchange ratio of 0.90).

THE MERGER AGREEMENT

CONVERSION OF SECURITIES (PAGE __)

         In the merger, CI Subsidiary will be merged with and into NetOptix.
NetOptix will be the surviving corporation and will continue as a wholly-owned
subsidiary of Corning. As a result of the merger, you will be entitled to
receive 0.90 of a share of Corning common stock for each share of NetOptix
common stock that you own. You will not receive fractional shares of Corning
common stock. Instead, you will receive a cash payment for any fractional shares
you might otherwise have been entitled to receive, based on the market value of
the Corning common stock.

         Each NetOptix stock option outstanding at the effective time of the
merger will be assumed by Corning and will become an option to purchase that
number of shares of Corning common stock equal to the product of:

         -    the number of shares of NetOptix common stock issuable upon
              exercise of the stock option; and

                                      -5-
<PAGE>

         -    0.90.

         The exercise price per share of each converted stock option will be
equal to the result of:

         -    The exercise price per share of NetOptix common stock under the
              original stock option; divided by

         -    0.90.

         In the case of any NetOptix stock option to which Section 422 of the
Internal Revenue Code of 1986, as amended, applies, the exercise price and the
number of shares purchasable pursuant to such NetOptix stock option will be
determined in order to comply with Section 424(h) of the Internal Revenue Code.

CONDITIONS TO CLOSING (PAGE ___)

         Corning's and NetOptix's obligations to complete the merger are subject
to the satisfaction or waiver of several conditions, including the following:

         -    holders of a majority of the outstanding shares of NetOptix's
              common stock approve the adoption of the merger agreement;

         -    the shares of Corning common stock to be issued in the merger and
              reserved for issuance upon exercise of NetOptix stock options and
              warrant are authorized for listing on the New York Stock Exchange,
              subject to official notice of issuance;

         -    no court order prohibits the merger or makes the merger illegal;

         -    Corning and NetOptix obtain all regulatory approvals and third
              party consents necessary to complete the merger;

         -    each of Corning and NetOptix has certified to the other that its
              representations and warranties are true and correct except as
              would not have a material adverse effect and that its material
              obligations under the merger agreement have been complied with in
              all material respects; and

         -    each of Corning and NetOptix has obtained an opinion from tax
              counsel that the merger will qualify as a tax-free reorganization.

NO SOLICITATION PROVISION (PAGE ___)

         NetOptix has agreed that it will not solicit or encourage the
initiation of any proposals regarding alternative acquisition transactions with
third parties. If NetOptix receives such a proposal, it must promptly notify
Corning. The NetOptix board of directors may respond to certain unsolicited
written proposals regarding alternative acquisition transactions and may
recommend such transaction proposals to NetOptix's stockholders only under
limited circumstances.

         Under limited circumstances, NetOptix may be required to pay Corning
the termination fee described below. The no-solicitation and the termination fee
provisions of the merger agreement may have the effect of discouraging persons
who might be interested in entering into a business combination with NetOptix
from proposing a business combination transaction. This may be so even where the
consideration payable to NetOptix stockholders in the other transaction would
exceed the consideration payable in the merger.


                                      -6-
<PAGE>


         In addition, under the stockholder voting agreement and irrevocable
proxy, the principal stockholders of NetOptix: Andlinger Capital XIII LLC, Mr.
Andlinger, Mr. Magida, acting in his capacity as manager of Andlinger Capital
and as trustee of a trust for Mr. Andlinger and Mr. Blais have agreed to vote
their shares in favor of the merger and not to solicit other offers, among other
things. This agreement also has the effect of discouraging other persons who may
be interested in acquiring NetOptix.

TERMINATION AND TERMINATION FEES (PAGES ___ THROUGH ___)

         Corning and NetOptix can agree to terminate the merger agreement
without completing the merger and either company can terminate the merger
agreement if any of the following occurs:

         -    the other party materially breaches the merger agreement and does
              not cure such breach in all material respects;

         -    the merger is not completed by July 31, 2000 so long as the
              terminating party is not otherwise in material breach of the
              merger agreement;

         -    a court order permanently prohibits the merger; or

         -    NetOptix's stockholders do not approve the merger, in which case,
              under certain conditions, NetOptix must pay the termination fee
              described below.

         NetOptix also may terminate the merger agreement if the following
occurs, in which case, under certain conditions, NetOptix must pay the
termination fee described below:

         -    if NetOptix receives a superior acquisition proposal, before the
              special meeting, from a potential acquirer that the NetOptix board
              of directors considers to be a more favorable competing offer;

         -    NetOptix provides Corning with sufficient notice of its decision
              to terminate as required by the merger agreement;

         -    Corning does not make an offer to NetOptix that the NetOptix board
              of directors considers to be at least as favorable as the
              competing offer; and

         -    NetOptix pays the termination fee described below.

         Corning also may terminate the merger agreement and, under certain
conditions, NetOptix must pay the termination fee described below, if the
NetOptix board of directors:

         -    withdraws or modifies its approval of the merger;

         -    enters into negotiations with any person concerning an acquisition
              proposal in violation of the merger agreement; or

         -    approves or recommends an acquisition proposal as materially more
              favorable to the stockholders of NetOptix.

         In these cases, NetOptix must pay the termination fee described below
unless:

         -    NetOptix has not received a competing offer or engaged in
              discussions with or provided confidential information to any
              person in respect of any acquisition proposal; and

                                      -7-
<PAGE>


         -    the NetOptix board of directors determines in good faith that it
              is obligated by its fiduciary duties to withhold or adversely
              change its recommendation of Corning's offer.

         As noted above, under certain circumstances, if the merger agreement is
terminated, NetOptix may be required to pay Corning a termination fee of up to
$50 million. One-half of the termination fee, $25 million, is due and must be
paid by NetOptix within two days of notice of termination of the merger
agreement. The remaining one-half of the termination fee must be paid when
NetOptix closes any acquisition transaction entered into within twelve months
after termination of the merger agreement.

EXPENSES (PAGE ___)

         All costs and expenses will be paid by the party incurring them, except
that in the event the merger agreement is terminated in accordance with its
terms, Corning will pay the costs and expenses of filing and printing this proxy
statement/prospectus and of filings with certain governmental authorities in
connection with the merger.

REGULATORY APPROVALS (PAGES ___ THROUGH ___)

         On April __, 2000, the required waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act relating to the merger will
terminate. The Antitrust Division of the Department of Justice and the Federal
Trade Commission continue to have the authority to challenge the merger on
antitrust grounds before and after the merger is completed.

         NetOptix and Corning are required to make filings with, or obtain
approvals from, some other international regulatory authorities in connection
with the merger. Corning and NetOptix expect that none of these regulatory
authorities would prohibit consummation of the merger. However, we cannot assure
you that the required consents, approvals and authorizations will be obtained.

NO APPRAISAL RIGHTS (PAGE __)

         Under applicable Delaware law, you do not have any right to an
appraisal of the value of your shares in connection with the merger since the
shares of NetOptix common stock are traded on NASDAQ.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES (PAGES ___ THROUGH ___)

         Corning's tax counsel, Nixon Peabody LLP, and NetOptix's tax counsel,
Edwards & Angell LLP, will each provide an opinion that the merger qualifies as
a reorganization within the meaning of Section 368(a) of the Internal Revenue
Code. NetOptix stockholders will not be taxed as a result of the exchange of
NetOptix common stock for Corning common stock in the merger, unless and only to
the extent they receive a payment for fractional shares. Receipt of the Nixon
Peabody LLP opinion is a condition to the closing of the merger.

         THE TAX CONSEQUENCES OF THE MERGER TO YOU WILL DEPEND ON THE FACTS OF
YOUR OWN SITUATION. YOU SHOULD CONSULT YOUR TAX ADVISORS FOR A FULL
UNDERSTANDING OF THE TAX CONSEQUENCES OF THE MERGER TO YOU.

ACCOUNTING TREATMENT (PAGE ___)

         Corning will account for the merger under the purchase method of
accounting in accordance with generally accepted accounting principles. The
purchase price will be allocated based on the fair value of the assets acquired
and the liabilities assumed. Any excess of the purchase price will be allocated
to

                                      -8-
<PAGE>

goodwill and any acquired in-process research and development will be charged
to expense in the period in which the transaction closes.

RISK FACTORS RELATING TO THE MERGER (PAGE ___)

         You should consider the following risk factors, among others, in
deciding how to vote at the special meeting:

              -   the consideration is a fixed exchange ratio, which will not be
                  adjusted as a result of any increase or decrease in the price
                  of either Corning or NetOptix common stock; and

              -   integrating Corning's and NetOptix's photonics business
                  operations may be difficult.

======================================================================================================================
</TABLE>


(a)    During the third quarter of 1999, Corning sold Republic Wire and Cable, a
       manufacturer of elevator cables and a subsidiary of Siecor Corporation,
       for approximately $52 million in cash and short-term notes. Corning
       recorded a non-operating gain of $30 million ($9.5 million after tax and
       minority interest) or $0.04 per share as a result of this transaction.

(b)    In the third quarter of 1999, Corning recognized an impairment loss of
       $15.5 million pretax ($10.0 million after tax), or $0.04 per share, in
       connection with management's decision to sell Quanterra Incorporated. The

                                      -10-
<PAGE>

       impairment loss reduces Corning's investment in these assets to an amount
       equal to management's current estimate of fair value. Disposition of the
       business occurred in February 2000.

(c)    In the second quarter of 1998, Corning recorded a restructuring charge of
       $84.6 million ($49.2 million after tax and minority interests), or $0.19
       per share. During the fourth quarter of 1999, Corning determined that the
       actual costs of certain benefits included in the retirement incentive
       program were less than estimated in the second quarter of 1998 and
       released restructuring reserves totaling $14.1 million ($8.6 million
       after tax) or $0.03 per share.

(d)    During the fourth quarter of 1999, certain indemnification agreements
       related to the April 1998 sale of Corning's consumer housewares business
       expired. As a result, Corning recognized income from discontinued
       operations of $7.8 million ($4.8 million after tax) or $0.02 per share in
       the fourth quarter from the release of reserves provided at the date of
       the transaction.

(e)    In the second quarter of 1998, Molecular Simulations, Inc. (MSI) merged
       with Pharmacopeia, Inc., a publicly traded company (NASDAQ: PCOP).
       Corning previously owned 35% of MSI and owned approximately 15% of the
       combined entity at the time of the merger. Corning realized a gain of
       $20.5 million ($13.2 million after tax), or $0.05 per share, from this
       transaction.

(f)    In the fourth quarter of 1998, Corning recorded a non-operating gain of
       $19.2 million ($9.7 million after tax), or $0.04 per share, related to
       the divestiture of several small businesses within the science products
       division.

(g)    On April 1, 1998, Corning completed the recapitalization and sale of a
       controlling interest in its consumer housewares business to an affiliate
       of Borden, Inc. Corning received cash proceeds of $593 million and
       continues to retain a 3% interest in World Kitchen Inc., formerly the
       Corning Consumer Products Company. Corning recorded an after-tax gain of
       $67.1 million, or $0.26 per share, in the second quarter of 1998. The
       $66.5 million net income from discontinued operations includes a $0.6
       million loss from operations of the discontinued business through March
       31, 1998.

(h)    During 1996 Oak Industries, Inc. sold its 49% interest in Video 44 (WSNS
       - TV Channel 44) and recorded a pre-tax gain of $20.5 million ($12.7
       million after tax), or $0.05 per share. Oak Industries also sold its 45%
       interest in O/E/N India Ltd. for a pre-tax gain of $1.0 million ($0.6
       million after tax).

(i)    On December 31, 1996, Corning distributed all of the shares of Quest
       Diagnostics Incorporated and Covance Inc., which collectively comprised
       Corning's Health Care Services segment, to its shareholders on a pro rata
       basis (the Distribution). Corning recorded a provision for loss on the
       Distributions of $176.5 million after tax, or $0.69 per share.

(j)    During 1996, Oak Industries, Inc. sold its Nordco Inc. subsidiary for an
       after tax gain of $9.4 million. Included in income from discontinued
       operations is income related to Nordco of $1.4 million after tax and $2.5
       million after tax in 1996 and 1995 respectively.

(k)    Oak Industries Inc.'s previously existing $30 million and $200 million
       credit agreements were terminated on August 30, 1995 and November 1,
       1996, respectively. As a result, Oak Industries recorded non-cash, after
       tax charges of $1.6 million and $0.9 million in 1995 and 1996,
       respectively, related to the early extinguishment of the former credit
       facilities.

(l)    In 1995, Corning recognized a restructuring charge from continuing
       operations totaling $26.5 million ($16.1 million after tax), as a result
       of severance for workforce reductions in corporate staff groups and the
       write-off of production equipment caused by the decision to exit the
       manufacturing facility for glass-ceramic memory disks.

       Corning also recorded an after-tax charge of $365.5 million to fully
       reserve its investment in Dow Corning Corporation (a 50%-owned equity
       company) as a result of Dow Corning Corporation filing for protection
       under Chapter 11 of the United States Bankruptcy Code in May 1995.
       Corning recognized equity earnings totaling $17.5 million from Dow
       Corning Corporation in the first quarter of 1995.

                                      -11-
<PAGE>

       Corning discontinued recognition of equity earnings from Dow Corning
       Corporation beginning in the second quarter of 1995.

(m)    Income from continuing operations included an after tax charge of $80.9
       million for purchased in-process research and development related to the
       acquisition of Lasertron.

(n)    In February of 2000, Corning completed an offering of Euro-denominated
       securities which generated net proceeds of $485 million. Corning used a
       portion of the proceeds as long-term financing of a piece of the cash
       purchase price for the acquisition of Siemens AG's worldwide optical
       cable and hardware business and the remaining 50% of its investment in
       Siecor Corporation and Siecor GmbH. The purchase price of $1.4 billion
       included approximately $120 million of assumed debt and contingent
       consideration of $145 million.

(o)    Corning closed an equity offering of 14,950,000 shares of its common
       stock on January 28, 2000. The transaction generated net proceeds of $2.2
       billion of which approximately $1.13 billion was used to fund a portion
       of the purchase price for the Siemens acquisition.

(a)    Results of operations and earnings per share data for fiscal years 1997
       through 1999 have been restated to reflect NetOptix's discontinued
       operations. Since continuing operations principally reflect the optical
       filter business, as it was acquired in January 1998, the periods ended
       September 30, 1996 and 1995 were not restated as such information would
       not be meaningful. See Note 5, "Discontinued Businesses," to NetOptix's
       Consolidated Financial Statements contained in its annual report on Form
       10-K for the year ended September 30, 1999 incorporated by reference into
       this proxy statement/prospectus.

(b)    NetOptix was in violation of certain of its covenants and therefore the
       loan balance of $13,596 is classified as a short-term liability at
       December 31, 1998.

SELECTED UNAUDITED PRO FORMA COMBINED SUPPLEMENTAL FINANCIAL INFORMATION

         The following describes the pro forma effect of the merger on Corning's
unaudited supplemental statements of income information for the year ended
December 31, 1999, and the unaudited supplemental balance sheet information as
of December 31, 1999. You should read this selected information in conjunction
with the "Unaudited Pro Forma Combined Financial Information"

                                      -13-
<PAGE>

and the accompanying notes included elsewhere in this proxy statement/prospectus
and the historical financial information and related notes of Corning and
NetOptix, incorporated by reference in this proxy statement/prospectus. The
unaudited pro forma combined supplemental financial information is provided for
informational purposes only and does not purport to represent what the financial
position and results of operations of the combined company would actually have
been had the merger in fact occurred at the dates indicated. The unaudited pro
forma combined supplemental statement of income information and combined
balance sheet information illustrate the estimated effects of the merger as if
the merger had occurred at January 1, 1999, for the statements of income
information and at December 31, 1999 for the balance sheet information. The
unaudited pro forma combined supplemental statements do not include the impact
of non-recurring charges directly attributable to the merger.

         Corning will account for the merger under the purchase method of
accounting in accordance with generally accepted accounting principles. The
purchase price will be allocated based on the fair values of the assets acquired
and the liabilities assumed. Any excess of the purchase price will be allocated
to goodwill and any acquired in-process research and development will be charged
to expense in the period in which the transaction closes. Adjustments have been
made to reclassify the presentation of NetOptix historical financial information
to be consistent with Corning's presentation. However, no adjustments have been
made in the unaudited pro forma combined financial information of Corning and
NetOptix to conform the accounting policies of the combined company as the
nature and amounts of such adjustments are not expected to be significant.

COMPARATIVE PER SHARE INFORMATION

         The following table summarizes on a per share basis certain (1)
historical financial information and (2) unaudited pro forma and equivalent pro
forma financial information.

         The unaudited pro forma supplemental financial information illustrates
the estimated effects of the merger as if the merger had occurred at January 1,
1999 for the statement of income information and at December 31, 1999 for the
balance sheet information. The unaudited pro forma financial information has
been prepared based on the purchase method of accounting and does not include
the impact of non-recurring charges directly attributable to the merger. The
basic unaudited pro forma per share information for Corning is based on the
weighted average number of outstanding shares of Corning common stock adjusted
to include the number of shares of Corning common stock that would be issued in
the merger in exchange for the outstanding NetOptix common stock, based on the
number of shares of NetOptix common stock outstanding for the period reported.
The diluted unaudited pro forma per share information for Corning is based on
the weighted average number of outstanding shares of Corning common stock
adjusted to include (1) the dilutive effect of Corning employee stock options
and (2) the number of shares of Corning common stock that would be issued in the
merger. The effect of NetOptix employee stock options was not dilutive.

         The unaudited equivalent pro forma per share information for NetOptix
is based on the unaudited pro forma amounts per share for Corning multiplied by
the exchange ratio of 0.90. The information set forth below is qualified in its
entirety by reference to, and should be read in conjunction with, the historical
consolidated financial information of Corning and NetOptix incorporated by
reference in this proxy statement/prospectus and the "Unaudited Pro Forma
Combined Financial Information" included elsewhere in this proxy
statement/prospectus.

         (a) February 11, 2000 was the last full trading day before public
announcement of the signing of the merger agreement.

         Because the market price of Corning common stock is subject to
fluctuation, the market value of the shares of Corning common stock that holders
of NetOptix common stock will receive in the merger, and the market value of the
NetOptix common stock surrendered in the merger, may increase or decrease prior
to or after the merger. See "Risk Factors Relating to the Merger--Fixed Exchange
Ratio May Result in Lower Value of Merger Consideration" on page __.

         NETOPTIX STOCKHOLDERS ARE URGED TO OBTAIN CURRENT MARKET QUOTATIONS FOR
THE CORNING COMMON STOCK AND THE NETOPTIX COMMON STOCK.

                       RISK FACTORS RELATING TO THE MERGER

         You should consider the following risks, among others, in deciding
whether to approve the merger and adopt the merger agreement. These matters
should be considered along with the other information included or incorporated
by reference in this proxy statement/prospectus.

         FIXED EXCHANGE RATIO MAY RESULT IN LOWER VALUE OF MERGER CONSIDERATION.
Upon completion of the merger, each share of NetOptix common stock will be
converted into the right to receive 0.90 of a share of Corning common stock.

         The exchange ratio is fixed and will not be adjusted as a result of any
increase or decrease in the price of either Corning or NetOptix common stock.
Any change in the price of Corning common stock will affect the value the
NetOptix stockholders receive in the merger.

         In addition, because the merger will be completed only after all the
conditions to the merger are satisfied or waived, including the receipt of
regulatory approvals, there is no way to be sure that the price of Corning
common stock or NetOptix common stock at the time the merger is completed will
be the same as their prices on the date of the special meeting.

         Changes in the business, operations or prospects of Corning or
NetOptix, regulatory considerations, general market and economic conditions and
other factors may affect the prices of Corning common stock, NetOptix common
stock or both. Many of those factors are beyond our control. You are encouraged
to obtain current market quotations for both Corning common stock and NetOptix
common stock.

         INTEGRATING BUSINESS OPERATIONS MAY BE DIFFICULT AND MAY HAVE A
NEGATIVE IMPACT ON CORNING'S OPTICAL FILTER BUSINESS. The combination of
Corning's and NetOptix's optical filter business involves the integration of
separate businesses that have previously operated independently and have
different corporate cultures. The process of combining the companies may be
disruptive to their businesses and may cause an interruption of, or a loss of
momentum in, these businesses as a result of the following difficulties, among
others:

         -    loss of key employees or customers;

         -    possible inconsistencies in standards, controls, procedures
              and policies between the business being combined and the need
              to implement and harmonize company-wide financial, accounting,
              information and other systems;

         -    failure to maintain the speed and quality of production of
              optical filters that NetOptix and the photonics technologies
              division of Corning have historically provided; and

         -    the diversion of management's attention from the day-to-day
              businesses of the photonics technologies division of Corning
              and NetOptix as a result of the need to deal with the above
              disruptions and difficulties and/or the possible need to add
              management resources to do so.

         Such disruptions and difficulties, if they occur, may cause Corning to
fail to realize the benefits that it currently expects to result from the
integration of NetOptix.

           CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

         This document, and the documents incorporated by reference into this
proxy statement/prospectus, contain both historical and forward-looking
statements within the meaning of section 27A of the Securities Act of 1933 and
section 21E of the Securities Exchange Act of 1934. These forward-looking
statements are not based on historical facts, but rather reflect Corning's and
NetOptix's current expectations concerning future results and events. These
forward-looking statements generally can be identified by use of statements that
includes phrases such as "believe," "expect," "anticipate," "intend," "plan,"
"foresee," "likely," "will" or other similar words or phrases. Similarly,
statements that describe our objectives, plans or goals are or may be
forward-looking statements. These forward-looking statements involve known and
unknown risks, uncertainties and other factors which may cause the actual
results, performance or achievements of Corning and NetOptix to be different
from any future results, performance and achievements expressed or implied by
these statements. You should review carefully all information, including the
financial statements and the notes to the financial statements, included or
incorporated by reference into this proxy statement/prospectus.

         The following important factors could affect future results, causing
these results to differ materially from those expressed in our forward-looking
statements:

         -    product demand and industry capacity, competitive products and
              pricing, manufacturing efficiencies, cost reductions,
              availability and costs of critical materials, new product
              development and commercialization, manufacturing capacity,
              facility expansions and new plant start-up costs;

         -    changes in economic conditions such as inflation, interest rates
              and foreign currency exchange rates;

         -    acquisition and divestiture activity, capital resource and cash
              flow activities and capital spending;

         -    changes in tax requirements, including tax rate changes, new tax
              laws and revised tax law interpretations; and

         -    the effect of regulatory and legal developments, the rate of
              technological change and the ability to preserve trade secrets
              and enforce patents.

RECORD DATE

         The NetOptix board of directors has fixed the close of business on

NetOptix common stock on the record date will be entitled to vote at the special
meeting and any adjournments or postponements thereof. At the record date,
__________ shares of NetOptix common stock were outstanding and entitled to vote
held by approximately _____ holders of record.

         The presence, in person or by proxy, of a majority of the shares of

meeting. Abstentions will be included in the determination of shares present and
entitled to vote at the special meeting for purposes of determining a quorum. If
a broker indicates on the proxy that it does not have discretionary authority as
to certain shares to vote on a particular matter, then those shares will not be
considered as present and entitled to vote with respect to that matter.

REQUIRED VOTES

         All properly executed proxies delivered and not properly revoked will
be voted at the special meeting as specified in such proxies. If you do not
specify a choice, your shares represented by a signed proxy will be voted for
the approval of the merger agreement.

         A majority vote of the shares of NetOptix common stock outstanding and
entitled to vote on the record date is required to approve the merger and adopt
the merger agreement. Non-voting shares, including abstentions, and shares held
by brokers who are not given authority to vote in favor of the


                                      -22-
<PAGE>

merger ("broker non-votes") will have the effect of a vote against the merger
agreement. On the record date, NetOptix's executive officers and directors
collectively beneficially owned an aggregate of 4,019,117 shares of NetOptix
common stock or approximately 35.05% of the outstanding common stock. In
addition, a total of 3,978,117 shares of NetOptix common stock (5,003,117 shares
if the Andlinger Capital XIII LLC warrants and the vested portion of the ANC
Management options are exercised prior to the special meeting) is subject to the
stockholder voting agreement and irrevocable proxy described under "Interests of
Directors and Officers in the Merger" and attached as Annex C to this proxy
statement/prospectus.

         If sufficient votes in favor of the merger proposal are not received by
the time scheduled for the special meeting, the persons named as proxies may
propose one or more adjournments of the special meeting to permit further
solicitation of proxies. The persons named as proxies will vote in favor of any
adjournment those proxies which authorize them to vote in favor of the merger.
They will vote against any adjournment those proxies which direct them to vote
against the merger. Any such adjournment will require the affirmative vote of a
majority of the votes cast (or if a quorum is not present, a majority of the
votes represented in person or by proxy) at the session of the special meeting
to be adjourned. The costs of any such additional solicitation and of any
adjourned session will be borne by NetOptix.

PROXIES, VOTING AND REVOCATION

         This proxy statement/prospectus is being furnished to NetOptix's
stockholders in connection with the solicitation of proxies by, and on behalf
of, the NetOptix board of directors for use at the special meeting, and is
accompanied by a form of proxy.

         Each share of NetOptix common stock is entitled to one vote. Votes will

01566). You may also revoke your proxy by signing and returning a duly executed
proxy bearing a later date or by appearing at the special meeting in person,
notifying the Secretary and voting by ballot at the special meeting.

         If you attend the meeting, you may vote in person whether or not you
have previously given a proxy, but your presence, without notifying the
Secretary of NetOptix, at the meeting will not revoke a previously given proxy.
In addition, if you beneficially hold shares of NetOptix common stock that are
not registered in your own name, you will need additional documentation from the
record holder of those shares to attend and vote the shares personally at the
meeting.

SOLICITATION OF PROXIES

                                   THE MERGER

BACKGROUND OF THE MERGER

         On January 25, 2000, the President of NetOptix's optical filter
subsidiary, Optical Filter Corporation, was approached by the Business Manager
of Components for Corning who requested a confidential meeting. The NetOptix
President, Corning's Business Manager of Components and a Corning Vice President
for Corporate Development met at dinner and discussed Corning's interest in
exploring options concerning the acquisition of NetOptix's optical filter
business.

         On January 26, 2000, the Chairman of the Board and Chief Executive
Officer of NetOptix received a phone call from Corning's Vice President of
Corporate Development at which time they agreed to meet in New York City.

         On January 28, 2000, representatives of Corning met with
representatives of NetOptix in New York City. The Chairman of NetOptix and the
Corning Vice President executed a confidentiality agreement on behalf of their
respective companies. The participants discussed the possibility of a business
combination between Corning and NetOptix and the potential terms of such a
combination.

         Corning and NetOptix representatives met again on January 31, 2000, at
the Optical Filter Corporation facility in Natick, Massachusetts to discuss
filter technology, planned ramp-up of production, the 12-month financial
projections for filter products and the corporate history of NetOptix. The
President of Optical Filter Corporation delivered a presentation on filter
technology and financial projections.

         On February 4, 2000, Corning provided a written preliminary proposal
letter to the Chairman of NetOptix. The proposal letter set forth the potential
terms of the proposed acquisition of NetOptix by Corning.

         On February 7, 2000, the NetOptix board of directors met in Boston to
discuss the Corning proposal and to select a financial advisor to NetOptix in
connection with evaluation of the Corning proposal. The NetOptix board of
directors approved the engagement of Salomon Smith Barney Inc. to serve as the
financial advisor to NetOptix in connection with the Corning proposal and other
potential transactions. The NetOptix board of directors also determined that
senior management of NetOptix should continue discussions with Corning and
conduct further due diligence analysis as well as negotiate the terms of
definitive documentation on the basis of the preliminary proposal from Corning.

         On February 8, 2000, the first negotiating session between NetOptix and
Corning was held in the Boston office of Edwards & Angell, LLP. NetOptix
representatives included the Chairman, the President, the Vice President and
Chief Financial Officer of NetOptix and several members of the NetOptix board of
directors, as well as its financial and legal advisors. Corning was represented
by its financial advisors and senior management, including its Senior Vice
President-General Counsel, Vice President and Director, Legal Department and
Vice President for Corporate Development.

         Discussions and negotiations continued from February 8, 2000 through
February 13, 2000 with respect to the transaction. During this time, each party
conducted due diligence, and senior management

                                      -24-
<PAGE>

of Corning and NetOptix were then separately briefed on the findings that their
teams had reached during due diligence. The parties and their respective
financial and legal advisors met frequently during this period to discuss the
financial and other terms of the proposed transaction, including the exchange
ratio.

         The NetOptix board of directors held two special meetings during this
time, the first on February 11, 2000 and the second on February 13, 2000, at
which senior management of NetOptix reviewed with the NetOptix board of
directors its discussions and negotiations with Corning regarding the
transaction, as well as the results of its due diligence investigation of
Corning. At both meetings, the NetOptix board of directors discussed with
counsel to NetOptix the terms of the merger agreement and the stockholder voting
agreement and irrevocable proxy, and the legal standards applicable to its
decision to approve the merger agreement and the transactions contemplated by
the merger agreement. Salomon Smith Barney Inc. and the senior management of
NetOptix presented to the NetOptix board of directors financial information with
respect to Corning and the proposed transaction. At the February 13, 2000
meeting Salomon Smith Barney Inc., rendered its oral opinion (which was
subsequently confirmed in writing) that, as of February 13, 2000, the exchange
ratio contemplated in the merger agreement was fair to holders of NetOptix
common stock from a financial point of view. After questions by and discussion
among the members of the NetOptix board of directors, and after consideration of
the factors described under "--Reasons for the Merger; Recommendation of the
NetOptix Board of Directors," the NetOptix board of directors voted unanimously,
on February 13, 2000, to approve the merger agreement and the transactions
contemplated by the merger agreement.

                  The merger documents were executed during the evening of
February 13, 2000 and arrangements were made by Corning and NetOptix to release
announcements of the merger transaction simultaneously at 7:00 a.m. EST on
February 14, 2000.

REASONS FOR THE MERGER; RECOMMENDATION OF THE NETOPTIX BOARD OF DIRECTORS

         In reaching its conclusion to approve the merger agreement, the
NetOptix board of directors consulted with management of NetOptix, as well as
its financial and legal advisors and considered a number of factors, as
described below.

- -    The NetOptix board of directors considered the effect of the merger on
     implementing and accelerating NetOptix's basic long-term growth strategy in
     light of the current economic, financial and business environment, the
     limited size of NetOptix, its limited financial resources and customer base
     and its dependence on a single line of business.

- -    The NetOptix board of directors analyzed NetOptix's financial condition,
     results of operations, business and prospects, and compared them to those
     of the combined companies. In considering this financial information, the
     NetOptix board of directors took into account NetOptix's and Corning's
     recent and historic stock prices and earnings performances, as well as its
     own analysis of the business opportunities presented by the merger and
     current market trends relating to NetOptix's products and Corning's recent
     moves to expand its telecommunications business and reposition its business
     mix. The NetOptix board of directors considered the financial analyses
     and pro forma and other financial data presented by Salomon Smith Barney,
     information concerning Corning and its business strategy presented by
     Corning, analyses performed by NetOptix management, as well as the NetOptix
     board of directors' own knowledge of the industry and of NetOptix and
     Corning and their respective businesses.

- -    The NetOptix board of directors considered the price and other terms of the
     merger agreement, as well as other information concerning the merger,
     including the structure of the merger. Among other things, the board of
     directors considered the expectation that the merger will be treated as a
     tax-free transaction for U.S. federal income tax purposes to NetOptix
     stockholders. See "The Merger--Material Federal Income Tax Consequences" on
     page [ ].

- -    The NetOptix board of directors considered Corning's strong research and
     development capabilities, and its existing commitment to the optical filter
     market, which would significantly strengthen NetOptix's existing technology
     and product development efforts, Corning's financial resources, customer
     relationships and commitment to drive NetOptix's business forward.

- -    The NetOptix board of directors considered the alternatives available to
     NetOptix in lieu of the transaction, including acquisitions or joint
     ventures and remaining as a stand-alone entity.

- -    The NetOptix board of directors considered the benefits of the merger,
     including its view that the combined company might be able to capitalize on
     operational and competitive elements that may not be available otherwise to
     NetOptix on a stand-alone basis.

- -    The NetOptix board of directors considered the opportunity for you to
     become holders of Corning common stock, which the NetOptix board of
     directors believed would perform at least as well as NetOptix common stock
     over the long term and would have greater liquidity and lower volatility
     than NetOptix common stock.

- -    The NetOptix board of directors considered the opinion of Salomon Smith
     Barney Inc. that as of the date of that opinion the exchange ratio under
     the merger agreement was fair from a financial point of view to holders of
     NetOptix common stock.

                                      -26-
<PAGE>


- -    The NetOptix board of directors considered Corning's reputation and
     policies with respect to its employees, and the impact on NetOptix's
     employees of becoming employees of Corning.

- -    The NetOptix board of directors considered economies of scale because the
     telecommunications industry, particularly the fiberoptics transmission
     materials industry, is currently characterized by intense competition and
     large-scale consolidation.

- -    The NetOptix board of directors considered the effect on NetOptix
     stockholders of NetOptix continuing as a stand-alone entity compared to the
     effect of NetOptix combining with Corning, in light of the factors
     summarized above.

         The NetOptix board of directors also considered a number of potential
risks relating to the merger, including risks relating to a fixed exchange ratio
despite potential changes in relative stock prices, the difficulty and
management distraction inherent in integrating two businesses, and the risk that
the merger would not be consummated. See "Risk Factors Relating to the Merger"
on page _____. The NetOptix board of directors believed that these risks were
outweighed by the potential benefits to be realized from the merger.

         The foregoing discussion of the information and factors considered by
the NetOptix board of directors is not intended to be exhaustive, but is
believed to include all material factors considered by the NetOptix board of
directors in approving the merger. In view of the wide variety of information
and factors considered, the NetOptix board of directors did not find it
practical to, and did not, assign any relative or specific weights to the
foregoing factors and individual directors may have given differing weights to
different factors.

         For a discussion of the interests of members of NetOptix's management
and Board in the merger, see "Interests of Directors and Officers in the Merger"
below. The NetOptix board of directors recognized these interests and determined
that these interests neither supported nor detracted from the fairness of the
merger to NetOptix's stockholders.

         THE NETOPTIX BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT
STOCKHOLDERS VOTE "FOR" APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.

                      OPINION OF SALOMON SMITH BARNEY INC.

         Salomon Smith Barney was retained to act as financial advisor to
NetOptix in connection with the merger. Pursuant to Salomon Smith Barney's
engagement letter with NetOptix, dated February 8, 2000, Salomon Smith Barney
rendered an opinion to the NetOptix board of directors on February 13, 2000 to
the effect that, based upon and subject to the considerations and limitations
set forth in the opinion, its work described below and other factors it deemed
relevant, as of that date, the exchange ratio was fair, from a financial point
of view, to the holders of NetOptix common stock.

         The full text of Salomon Smith Barney's opinion, which sets forth the
assumptions made, general procedures followed, matters considered and limits on
the review undertaken, is included as Annex B to this document. The summary of
Salomon Smith Barney's opinion set forth below is qualified in its entirety by
reference to the full text of the opinion. STOCKHOLDERS ARE URGED TO READ
SALOMON SMITH BARNEY'S OPINION CAREFULLY AND IN ITS ENTIRETY.

         In arriving at its opinion, Salomon Smith Barney reviewed a draft of
the merger agreement, dated February 11, 2000, and held discussions with certain
senior officers, directors and other representatives and advisors of NetOptix
and Corning concerning the businesses, operations and prospects of NetOptix and
Corning. Salomon Smith Barney examined publicly available business and financial
information

                                      -27-
<PAGE>

relating to NetOptix and Corning as well as financial forecasts and other
information and data for NetOptix and Corning which were provided to or
otherwise discussed with Salomon Smith Barney by the managements of NetOptix and
Corning, including certain strategic implications and operational benefits
anticipated to result from the merger. Salomon Smith Barney reviewed the
financial terms of the merger as set forth in the merger agreement in relation
to, among other things:

         -    current and historical market prices and trading volumes of
              NetOptix common stock and Corning common stock;

         -    the historical and estimated earnings and other operating data of
              NetOptix and Corning; and

         -    the historical and estimated capitalization and financial
              condition of NetOptix and Corning.

         Salomon Smith Barney also considered, to the extent publicly available,
the financial terms of other similar transactions recently effected that Salomon
Smith Barney considered relevant in evaluating the exchange ratio and analyzed
financial, stock market and other publicly available information relating to the
businesses of other companies whose operations Salomon Smith Barney considered
relevant in evaluating those of NetOptix and Corning. Salomon Smith Barney also
evaluated the pro forma financial impact of the merger on Corning. In addition,
Salomon Smith Barney conducted such other analyses and examinations and
considered such other information and financial, economic and market criteria as
it deemed appropriate in arriving at its opinion.

         In rendering its opinion, Salomon Smith Barney assumed and relied,
without independent verification, upon the accuracy and completeness of all
financial and other information and data publicly available or furnished to or
otherwise reviewed by or discussed with Salomon Smith Barney and further relied
on the assurances of management of NetOptix and Corning that they were not aware
of any facts that would make any of such information inaccurate or misleading.
With respect to financial forecasts and other information and data provided to
or otherwise reviewed by or discussed with it, Salomon Smith Barney was advised
by the management of NetOptix and Corning that such forecasts and other
information and data had been reasonably prepared on bases reflecting the best
currently available estimates and judgments of the management of NetOptix and
Corning as to the future financial performance of NetOptix and Corning and the
strategic implications and operational benefits anticipated to result from the
merger. Salomon Smith Barney expressed no view with respect to such forecasts
and other information and data or the assumptions on which they were based.
Salomon Smith Barney assumed, with the consent of NetOptix's board of directors,
that the merger will be treated as a tax-free reorganization for U.S. federal
income tax purposes. Salomon Smith Barney did not make and was not provided with
an independent evaluation or appraisal of the assets or liabilities (contingent
or otherwise) of NetOptix or Corning nor did Salomon Smith Barney make any
physical inspection of the properties or assets of NetOptix or Corning. Salomon
Smith Barney assumed that the final terms of the merger agreement would not vary
materially from those set forth in the draft reviewed by Salomon Smith Barney.
Salomon Smith Barney further assumed that the merger will be consummated in a
timely fashion in accordance with the terms of the merger agreement, without
waiver of any of the conditions to the merger contained in the merger agreement.

         Salomon Smith Barney did not express any opinion as to what the value
of Corning common stock actually will be when issued in the merger or the price
at which Corning common stock will trade subsequent to the merger. Salomon Smith
Barney was not asked to consider, and its opinion does not address, the relative
merits of the merger as compared to any alternative business strategies that
might exist for NetOptix or the effect of any other transaction in which
NetOptix might engage. Salomon Smith Barney's opinion necessarily was based on
information available to it, and financial, stock market and

                                      -28-
<PAGE>

other conditions and circumstances existing and disclosed to Salomon Smith
Barney as of the date of the opinion.

         SALOMON SMITH BARNEY'S ADVISORY SERVICES AND OPINION WERE PROVIDED FOR
THE INFORMATION OF NETOPTIX'S BOARD OF DIRECTORS IN ITS EVALUATION OF THE
PROPOSED MERGER AND DID NOT CONSTITUTE A RECOMMENDATION OF THE MERGER TO
NETOPTIX OR A RECOMMENDATION TO ANY STOCKHOLDER AS TO HOW THAT STOCKHOLDER
SHOULD VOTE ON ANY MATTERS RELATING TO THE PROPOSED MERGER.

         In connection with rendering its opinion, Salomon Smith Barney made a
presentation to the NetOptix board of directors on February 13, 2000, with
respect to the material analyses performed by Salomon Smith Barney in evaluating
the fairness of the exchange ratio. The following is a summary of this
presentation. The summary includes information presented in tabular format. IN
ORDER TO UNDERSTAND FULLY THE FINANCIAL ANALYSES USED BY SALOMON SMITH BARNEY,
THESE TABLES MUST BE READ TOGETHER WITH THE TEXT OF EACH SUMMARY. THE TABLES
ALONE DO NOT CONSTITUTE A COMPLETE DESCRIPTION OF THE FINANCIAL ANALYSES. The
following quantitative information, to the extent it is based on market data,
is, except as otherwise indicated, based on market data as it existed at or
prior to February 11, 2000, and is not necessarily indicative of current or
future market conditions.

         Implied Historical Exchange Ratio.

         Salomon Smith Barney derived implied historical exchange ratios by
dividing the closing price per share of NetOptix common stock by the closing
price per share of Corning common stock for each trading day in the period from
February 11, 1999 though February 11, 2000. Salomon Smith Barney calculated that
the implied exchange ratio as of February 11, 2000 was 0.82, the highest implied
exchange ratio during the period was 0.84, and the lowest implied exchange ratio
during the period was 0.06. Salomon Smith Barney also calculated the average
implied exchange ratio for each of the following calendar periods ending
February 11, 2000:

                     Last 12 Months                     0.26

                     Last 9 Months                      0.31

                     Last 6 Months                      0.40

                     Last 3 Months                      0.52

         Salomon Smith Barney noted that in each case described above, the
implied exchange ratio or the average implied exchange ratio derived by Salomon
Smith Barney was lower than the exchange ratio in the merger.

         Comparable Companies Analyses.

         Salomon Smith Barney compared financial, operating and stock market
information, and forecasted financial information, for each of NetOptix and
Corning, with the same information for selected publicly traded companies that
operate in the fiber optical component manufacturing industry. The forecasted
financial information used by Salomon Smith Barney for the selected comparable
companies in the course of these analyses was based on information published by
certain investment banking firms as well as information published by First Call
Corporation. First Call Corporation compiles summaries of financial forecasts
published by various investment banking firms. With respect to NetOptix, the
forecasted financial information used by Salomon Smith Barney was based on
information provided by management, and with respect to Corning, the forecasted
financial information

                                      -29-
<PAGE>

used by Salomon Smith Barney was based on estimates published by certain
investment banking firms. Calculations were made based on the closing price per
common share of each company on February 11, 2000, which was $136.00 for
NetOptix and $165.75 for Corning.

         For NetOptix, the selected comparable companies considered by Salomon
Smith Barney were:

              -   Corning
              -   JDS Uniphase Corporation
              -   E-Tek Dynamics, Inc.
              -   SDL, Inc.

         For NetOptix and each of the selected comparable companies considered
in the NetOptix analysis, Salomon Smith Barney derived and compared, among other
things:

              -   the ratio of the closing price per common share of each
                  company on February 11, 2000, to (a) its estimated
                  earnings per share (EPS) for 2000, and (b) its estimated
                  EPS for 2001;

              -   the ratio of each company's firm value as of February 11,
                  2000, to (a) its estimated revenue for 2000, (b) its
                  estimated revenue for 2000 from sales of fiber optical
                  products, and (c) its estimated earnings before taking
                  into account interest expense, taxes, depreciation and
                  amortization (EBITDA) for 2000;

              -   the estimated growth rate in its revenue for 2000; and

              -   the implied percentage volatility in the closing price per
                  common share of each company over the twelve-month period
                  ended February 11, 2000, based on publicly available
                  trading information.

Firm value was calculated as the sum of the value of:

              -   all shares of common stock assuming the exercise of all
                  in-the-money options, warrants and convertible securities,
                  less the proceeds from such exercise; plus

              -   non-convertible indebtedness; plus

         Salomon Smith Barney noted that for each ratio derived, the result for
NetOptix was below the mean for the selected comparable companies. In addition,
Salomon Smith Barney noted that the implied common share price volatility for
the last twelve-month period derived for NetOptix was in excess of the upper
limit of the range derived for the selected comparable companies and was
substantially in excess of that derived for Corning (51.2%) which constituted
the lower limit of the range for the selected comparable companies.

         For Corning, the selected comparable companies considered by Salomon
Smith Barney were:

              -   NetOptix
              -   JDS Uniphase Corporation
              -   E-Tek Dynamics, Inc.
              -   SDL, Inc.

         For Corning and each of the selected comparable companies used in the
Corning analysis, Salomon Smith Barney derived and compared the same ratios and
other information as was used in the NetOptix analysis. The following table sets
forth the results of these analyses.

</TABLE>


         Salomon Smith Barney noted that for each ratio derived, the result for
Corning was below the mean for the selected comparable companies, and in the
case of the ratios of estimated revenue for 2000 to firm value, estimated
revenue from fiber optical sales for 2000 to firm value and estimated EBITDA for
2000 to firm value, the results for Corning were below the lower end of the
range for the selected comparable companies. Salomon Smith Barney also noted,
however, that the businesses of each of the selected comparable companies used
in the Corning comparable company analysis were more heavily concentrated in
fiber optics than that of Corning, and that the acquisition of NetOptix would
add further fiber optical manufacturing operations to Corning's business.

         Precedent Transaction Analysis.

         Salomon Smith Barney reviewed publicly available information for six
completed merger or acquisition transactions in the fiber optical components
manufacturing sector announced since January 28, 1999, involving at least one
publicly traded company. The precedent transactions considered by Salomon Smith
Barney were the following (in each case, the acquiror's name is listed first and
the acquired company's name is listed second): (i) Uniphase Corporation/JDS
Fitel Inc.; (ii) JDS Uniphase Corporation/Epitaxx, Inc.; (iii) JDS Uniphase
Corporation/Optical Coating Laboratory, Inc.; (iv) Corning/Oak Industries Inc.;
(v) JDS Uniphase Corporation/E-Tek Dynamics, Inc.; and (vi) Lucent Technologies
Inc./Ortel Corporation.

         For each precedent transaction and for the proposed acquisition of
NetOptix in the merger, Salomon Smith Barney derived the ratio of the firm value
of the acquired company based on the consideration paid in the transaction to:

                  -   the revenue of the acquired company for the last
                      twelve-month period prior to the announcement of the
                      transaction for which financial results were available;

                                      -32-
<PAGE>



                  -   the revenue from sales of fiber optical products of the
                      acquired company for the last twelve-month period prior to
                      the announcement of the transaction for which financial
                      results were available;

                  -   the estimated revenue of the acquired company for the
                      twelve-month period following the announcement of the
                      transaction;

                  -   the estimated revenue of the acquired company from sales
                      of fiber optical products for the twelve-month period
                      following announcement of the transaction; and

                  -   the estimated earnings of the acquired company before
                      interest expense and taxes (EBIT) for the twelve-month
                      period following the announcement of the transaction.

With respect to the proposed acquisition of NetOptix in the merger, Salomon
Smith Barney used an implied price per share of NetOptix common stock of
$149.18, based upon the exchange ratio and the closing price per share of
Corning common stock on February 11, 2000 ($165.75). With respect to the
financial information for the companies involved in the precedent transactions,
Salomon Smith Barney relied on information available in public documents, equity
research reports published by certain investment banks and First Call
Corporation estimates.

</TABLE>


         With respect to the calculation for NetOptix of the ratio of firm value
to revenue from sales of fiber optical products for the twelve-month period
preceding announcement of the transaction, Salomon Smith Barney annualized
NetOptix's actual revenue from sales of fiber optical products for the first
quarter of NetOptix 2000 fiscal year. Salomon Smith Barney believed that this
provided a more meaningful ratio than that would have been obtained using
revenue from sales of fiber optical products for NetOptix's 1999 fiscal year
given the relatively low amount of such revenue realized by NetOptix in that
year.

         Salomon Smith Barney noted that in each case shown above, the ratio
derived for NetOptix based on the implied price per share to be paid in the
merger, exceeded the median ratio derived for the precedent transactions, and in
each case (other than the ratio of firm value to the acquired company's
estimated revenue for the twelve-month period following announcement of the
transaction) the ratio derived for NetOptix exceeded the upper limit of the
range derived for the precedent transactions.

         Salomon Smith Barney also derived the implied premium paid per common
share in each precedent transaction based on the closing price per common share
of the acquired company one week prior to the announcement of the transaction.
These premiums ranged from 13.5% to 72.7%, with a median of 59.7%. Based on the
exchange ratio and the closing price per share of Corning common stock on
February 11, 2000, Salomon Smith Barney noted that the implied premium in the
merger was 127.3%


                                      -34-
<PAGE>

of the average per share closing price of NetOptix common stock over the 90-day
period prior to announcement of the merger and 49.5% of the average per share
closing price of NetOptix common stock over the 30-day period prior to
announcement of the merger.

         Accretion/Dilution Analysis.

         Salomon Smith Barney performed an analysis of the impact of the merger
on the future EPS of Corning and on the future EPS of Corning after eliminating
all goodwill charges to Corning's earnings resulting from the merger and other
transactions previously completed by Corning. Salomon Smith Barney made pro
forma adjustments to the estimated combined operating earnings of the merged
entity but did not take into account any anticipated cost savings, revenue
enhancements or other similar potential effects of the merger. Estimates for EPS
for NetOptix on a stand-alone basis were based on estimates published by certain
investment banking firms and NetOptix management estimates. Estimates for EPS
for Corning were based on estimates published by certain investment banking
firms.

         The following table shows the accretion or dilution to the EPS of
Corning expected to result from the merger.

         Relative Contribution Analysis.

                                      -35-
<PAGE>


         Salomon Smith Barney analyzed the relative contribution of each of
NetOptix and Corning to the pro forma merged entity with respect to certain
market and financial data. In performing this analysis, Salomon Smith Barney did
not take into account any anticipated cost savings, revenue enhancements or
other similar potential effects of the merger. Estimated financial data for
Corning were based on estimates published by various investment banks. Estimated
financial data for NetOptix were based on management estimates. In calculating
market capitalization, Salomon Smith Barney assumed that no premium will be paid
to NetOptix shareholders in the merger. The following table sets forth the
results of Salomon Smith Barney's relative contribution analysis.

                                    CORNING        NETOPTIX

Estimated Revenue for 2000          98.7%          1.3%
Estimated EBITDA for 2000           97.4%          2.6%
Estimated EBIT for 2000             96.4%          3.6%
Estimated Net Income for 2000       95.9%          4.1%
Market Capitalization               96.0%          4.0%

         Salomon Smith Barney compared the results set forth above to the
implied 4.2% pro forma fully diluted ownership interest in the merged entity
that the former shareholders of NetOptix will have immediately following the
completion of the merger.

         The preceding discussion is a summary of the material financial
analyses furnished by Salomon Smith Barney to the NetOptix board of directors,
but it does not purport to be a complete description of the analyses performed
by Salomon Smith Barney or of its presentations to the NetOptix board of
directors. The preparation of financial analyses and fairness opinions is a
complex process involving subjective judgments and is not necessarily
susceptible to partial analysis or summary description. Salomon Smith Barney
made no attempt to assign specific weights to particular analyses or factors
considered, but rather made qualitative judgments as to the significance and
relevance of all the analyses and factors considered and determined to give its
fairness opinion as described above. Accordingly, Salomon Smith Barney believes
that its analyses, and the summary set forth above, must be considered as a
whole, and that selecting portions of the analyses and of the factors considered
by Salomon Smith Barney, without considering all of the analyses and factors,
could create a misleading or incomplete view of the processes underlying the
analyses conducted by Salomon Smith Barney and its opinion. With regard to the
comparable companies analyses summarized above, Salomon Smith Barney selected
comparable public companies on the basis of various factors, including the size
and similarity of the line of business; however, no company utilized as a
comparison in these analyses, and no transaction utilized as a comparison in the
comparable transaction analyses summarized above, is identical to NetOptix or
Corning or the merger. As a result, these analyses are not purely mathematical,
but also take into account differences in financial and operating
characteristics of the subject companies and other factors that could affect the
transaction or public trading value of the subject companies and transactions to
which NetOptix and Corning and the merger are being compared. In its analyses,
Salomon Smith Barney made numerous assumptions with respect to NetOptix,
Corning, industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of NetOptix
and Corning. Any estimates contained in Salomon Smith Barney's analyses are not
necessarily indicative of actual values or predictive of future results or
values, which may be significantly more or less favorable than those suggested
by these analyses. Estimates of values of companies do not purport to be
appraisals or necessarily to reflect the prices at which companies may actually
be sold. Because these estimates are inherently subject to uncertainty, none of
NetOptix, Corning, the NetOptix board of directors, Salomon Smith Barney or any
other person assumes responsibility if future results or actual values differ
materially from the estimates. Salomon Smith Barney's analyses were prepared
solely as part of Salomon Smith Barney's analysis of the fairness of the
exchange ratio in the merger and were provided to the NetOptix board of
directors in that connection. The opinion of Salomon Smith Barney was only one
of the factors taken into consideration by the NetOptix board of directors in
making its determination to approve the

                                      -36-

merger agreement and the merger. See "Reasons for the Merger; Recommendation of
the NetOptix Board of Directors" on pages (__) through (__).

         Salomon Smith Barney is an internationally recognized investment
banking firm engaged in, among other things, the valuation of businesses and
their securities in connection with mergers and acquisitions, restructurings,
leveraged buyouts, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes. NetOptix selected Salomon
Smith Barney to act as its financial advisor on the basis of Salomon Smith
Barney's international reputation and Salomon Smith Barney's familiarity with
NetOptix. Salomon Smith Barney and its predecessors and affiliates have
previously provided and currently are providing investment banking services to
Corning unrelated to the merger, for which Salomon Smith Barney has received and
will receive customary compensation. In the ordinary course of its business,
Salomon Smith Barney and its affiliates may actively trade or hold the
securities of both NetOptix and Corning for its own account and for the account
of customers and, accordingly, may at any time hold a long or short position in
those securities. Salomon Smith Barney and its affiliates, including Citigroup
Inc. and its affiliates, may maintain relationships with NetOptix and Corning
and their respective affiliates.

         Pursuant to Salomon Smith Barney's engagement letter, NetOptix agreed
to pay Salomon Smith Barney the following fees for its services rendered in
connection with the merger: (i) $100,000, that became payable promptly upon
execution of the engagement letter, and (ii) 0.45% of the aggregate value of the
transaction (less the amount described in clause (i) above), that will become
payable promptly upon consummation of the merger. NetOptix has also agreed to
reimburse Salomon Smith Barney for its reasonable travel and other out-of-pocket
expenses incurred in connection with its engagement, including the reasonable
fees and disbursements of its counsel, and to indemnify Salomon Smith Barney
against specific liabilities and expenses relating to or arising out of its
engagement, including liabilities under the federal securities laws.

                INTERESTS OF DIRECTORS AND OFFICERS IN THE MERGER

         Certain members of NetOptix's management and the NetOptix board of
directors may be deemed to have certain interests in the merger that are in
addition to their interests as stockholders of NetOptix generally. The NetOptix
board of directors was aware of these interests and considered them, among other
matters, in approving and adopting the merger agreement and the transactions
contemplated by that agreement.

         -    A portion of the outstanding unvested stock options held by
              NetOptix officers and directors may, at NetOptix's option and with
              the holder's consent, become fully vested and exercisable prior to
              the effective time of the merger. As of March 16, 2000, options to
              purchase 122,500 shares of NetOptix common stock held by executive
              officers of NetOptix had become fully vested and exercisable.

         -    Options to purchase 100,000 shares of NetOptix common stock held
              by ANC Management Corp., a corporation 100% of which is owned by
              Mr. Andlinger, will be amended to remove conditions to the vesting
              of such options, other than the passage of time, and to eliminate
              their acceleration as of the effective time of the merger.

         -    NetOptix may, prior to the closing, amend options to purchase an
              aggregate of 150,000 shares of NetOptix common stock granted to
              members of the NetOptix board of directors in order to continue to
              permit exercise and vesting following the effective time of the
              merger and to permit their transfer for tax or estate planning
              purposes.

              aggregate of 381,450 shares of NetOptix common stock granted to
              employees of NetOptix (of which 140,000 were granted to NetOptix
              executive officers) in order to immediately vest these options if
              the employee is terminated without cause or resigns for good
              reason, in each case prior to January 27, 2003.

         -    NetOptix may, prior to the closing, amend the terms of the
              Non-Qualified Stock Option Agreement in connection with the ANC
              Management Options to permit the transfer of these options for tax
              or estate planning purposes.

         -    Andlinger Capital XIII LLC, Mr. Andlinger, Mr. Magida, a director
              of NetOptix, acting in his capacity as manager of Andlinger
              Capital XIII LLC and as trustee of the Gerhard R. Andlinger
              Intangible Asset Management Trust dated as of December 29, 1997,
              and Mr. Blais have entered into a stockholder voting agreement and
              irrevocable proxy, dated as of February 13, 2000. A total of
              3,978,117 shares (5,003,117 shares if the Andlinger Capital XIII
              LLC warrants and the vested portion of the ANC Management options
              are exercised prior to the special meeting) of NetOptix common
              stock is subject to this agreement representing 34.70 percent of
              the total number of shares of NetOptix common stock outstanding as
              of the record date. The stockholder voting agreement and
              irrevocable proxy is attached as Annex C. Under this agreement
              each stockholder:

              -  agreed to vote the shares of NetOptix beneficially owned by him
                 or it in favor of the merger and to approve the
                 merger agreement;

              -  granted Corning an irrevocable proxy to vote his or its shares
                 for the merger and against any proposal in conflict with the
                 merger; and

              -  agreed not to solicit any proposal from any third person which
                 would interfere with the merger with Corning.

         -    Andlinger Capital XIII LLC holds a warrant to purchase 1,000,000
              shares of NetOptix common stock for a price of $1.50 per share
              which will, as a result of the merger, and unless exercised prior
              thereto, be converted into a warrant to acquire 900,000 shares of
              Corning common stock at an exercise price equal to $1.66 ($1.50
              divided by the exchange ratio of 0.90).

         -    Under a letter agreement dated February 13, 2000, Raft T. Faber

              eligible to receive a bonus each year in an amount of up to one
              hundred percent of his base salary. At the closing date of the
              merger, Mr. Faber will be granted Corning restricted stock having
              a market value on the date of grant of $4,000,000 pursuant to
              Corning's Incentive Stock Plan and he will receive options to
              purchase 10,000 shares of Corning common stock. A definitive
              agreement with Mr. Faber will be reviewed and executed at a later
              date.

         -    Corning will indemnify and maintain directors and officers
              liability insurance for NetOptix's directors and officers for six

                        CERTAIN COMPENSATION ARRANGEMENTS

SEVERANCE AGREEMENTS

         NetOptix intends to enter into severance agreements with Thomas
Mathews, NetOptix's chief financial officer, and certain other employees of
NetOptix. These severance agreements will provide for retention of these
employees for a period, no longer than one year, as shall be satisfactory to
Corning. In addition, the agreements will provide for severance benefits equal
to twelve months of base salary for Mr. Mathews and six months for the remaining
employees, if the employee is terminated without cause or resigns for good cause
at any time prior to the end of the retention period specified by Corning and
provided for in the severance agreement.

EMPLOYMENT AGREEMENT

         On February 13, 2000, Corning entered into a letter agreement with Mr.
Faber to clarify the terms of his continued employment after the closing date of
the merger. Under his existing employment agreement with NetOptix, Mr. Faber
serves as President of NetOptix and President and Chief Executive Officer of
Optical Filter Corporation, a subsidiary of NetOptix, at an annual salary of
$225,000, with the opportunity to receive an annual bonus not to exceed 30% of
his annual salary. The existing employment agreement also provides for the grant
of options to buy a total of 35,000 shares of common stock pursuant to the
provisions of the 1991 Stock Option Plan, none of which have been exercised. Mr.
Faber also holds options to purchase an additional 135,000 shares of NetOptix
common stock. Under the letter agreement, Mr. Faber has agreed to serve as the
President and CEO of Corning NetOptix for a term of three years beginning at the
effective time of the merger. The letter agreement provides that Mr. Faber shall
be eligible to receive a bonus each year in an amount of up to one hundred
percent of his base salary. At the closing date of the merger, Mr. Faber will be
granted Corning restricted stock having a market value on the date of grant of
$4,000,000 pursuant to Corning's Incentive Stock Plan and he will receive
options to purchase 10,000 shares of Corning common stock. A definitive
agreement with Mr. Faber will be reviewed and executed at a later date.

                               EQUITY BASED AWARDS

OPTIONS

         Director Options. In January 2000, NetOptix granted to each of the
non-employee directors of NetOptix under the NetOptix 1999 Stock Option Plan for
Non-Employee Directors options to acquire an aggregate of 25,000 shares of
NetOptix common stock at an exercise price of $100 per share. Corning and
NetOptix have agreed that these options will remain in effect after the closing
of the merger and will be converted into options to purchase Corning common
stock at the exchange ratio of 0.90 shares of Corning common stock for each
share of NetOptix common stock in accordance with applicable income tax
guidelines. NetOptix may, prior to the closing:

         -    waive as a condition of exercising these options that the holder
              continue to be serving as a director of NetOptix at the time the
              options vest or are exercised;

         -    waive all provisions relating to termination of the option or
              restriction on exercise after termination of the optionee; and

         -    provide that the vesting of the options shall accelerate upon the
              death of the optionee.

         Except as described, unvested options will continue to vest over the
three-year period described in the applicable option agreements.

                                      -39-
<PAGE>

         Employee Options.

         1999 Stock Option Plan Grants

         General. In January 2000, NetOptix granted options to approximately 118
employees of NetOptix to purchase an aggregate of 371,450 shares of NetOptix
common stock at an exercise price of $100 per share. Of these options, 140,000
were granted to NetOptix executive officers. Corning and NetOptix have agreed
that these options will be converted into options to purchase Corning common
stock at the exchange ratio of 0.90 shares of Corning common stock for each
share of NetOptix common stock and otherwise in accordance with applicable
income tax guidelines. These options will continue in effect with the same
vesting schedule, subject to the terms and conditions set forth in the grant,
modified as described below.

         Incentive Stock Options. With respect to certain NetOptix employee
options granted as incentive stock options in January 2000, NetOptix may, prior
to the closing of the merger, modify the applicable options so that, if Corning
terminates an employee without cause or an employee resigns for good reason, in
each case prior to January 27, 2003, that employee's unvested options will
become immediately exercisable, effective at the time of termination or
resignation, and will remain exercisable after termination or resignation for
the period following the date of termination or resignation as specified in the
applicable option agreement.

         Non-qualified Stock Options. With respect to non-qualified options
granted in January 2000 to certain employees, NetOptix may, prior to the closing
of the merger, modify the applicable options so that, if Corning terminates an
employee without cause or an employee resigns for good reason, in each case
prior to January 27, 2003, that employee's unvested options will become
immediately exercisable, effective immediately prior to the time of such
termination or resignation, and will remain exercisable for the period following
the date of termination or resignation as specified in the applicable option
agreement.

         Other Employee/Director Options. With respect to other outstanding
options held by employees and directors, NetOptix may, prior to the closing of
the merger, modify the vesting provisions of any outstanding option, if
consented to by the holder of the option, so that those options will not vest
automatically upon the closing, but rather will continue to vest in accordance
with the vesting schedule set forth in the applicable option agreements as if no
"change of control" transaction had occurred. For those options granted to
directors and certain employees, NetOptix may remove all other conditions to
vesting or exercise, including the requirement that the option holder continue
to serve as a director or employee of NetOptix.

         ANC Management Corp. Option. With respect to the option to purchase
100,000 shares of NetOptix common stock held by ANC Management Corp. granted
pursuant to the Management Advisory and Consulting Agreement between NetOptix
and ANC, NetOptix may, prior to the closing of the merger, modify the terms of
this option to eliminate the automatic acceleration of the vesting of the option
upon the consummation of the merger. In addition, NetOptix may eliminate any
conditions to vesting, including the requirement that the ANC Management
Agreement remain in effect or that Mr. Andlinger remain as CEO, so that the only
condition to vesting will be the passage of time. In consideration of this
change, NetOptix will cause the ANC Management Agreement to be terminated at
closing without penalty or additional cost to NetOptix. ANC Management Corp. is
a corporation 100% owned by Mr. Andlinger.

         DIRECTORS' AND OFFICERS' INSURANCE; INDEMNIFICATION OF NETOPTIX
                             DIRECTORS AND OFFICERS

         The merger agreement provides that for not less than six years after
the closing, all rights to indemnification in favor of any director, officer,
employee and agent of NetOptix and its subsidiaries as provided in their
respective charter documents or in indemnification agreements with NetOptix or
any of its subsidiaries, will continue to the extent permitted under Delaware
law. The merger agreement also provides that Corning shall cause the surviving
corporation to pay all legal fees and other expenses in the event any director,
officer employee and agent of NetOptix and its subsidiaries become involved in
any action proceeding or investigation in connection with any matter occurring
before or at the closing of the merger.

         Furthermore, the merger agreement also provides that, for a period of
six years after the merger, Corning will provide, or will cause NetOptix to
provide, officers' and directors' liability insurance in respect of acts or
omissions occurring on or prior to the merger covering each present and former
officer and director of NetOptix currently covered by NetOptix's officers' and
directors' liability insurance policy. The terms and amount of such coverage
will be no less favorable than those of the policy in effect on February 13,
2000. Corning, however, will not be obligated to pay in any one year an amount
in excess of 200% of the annual premiums currently paid by NetOptix for such
insurance. If the premium for the above coverage would exceed this amount, then
the surviving corporation would be obligated only to purchase a policy with the
greatest coverage available for that amount.

                    MATERIAL FEDERAL INCOME TAX CONSEQUENCES

         The following is a summary of material U.S. federal income tax
consequences of the merger to holders or other beneficial owners of NetOptix
common stock that are U.S. persons and that hold such stock as a capital asset
as defined in Section 1221 of the Internal Revenue Code of 1986, as amended
(generally, property held for investment is a capital asset). For these
purposes, you are a U.S. person if you are either (1) a citizen or resident of
the United States for U.S. federal income tax purposes, (2) a corporation or
partnership created or organized in or under the laws of the United States or
any political subdivision thereof, (3) an estate, the income of which is subject
to U.S. federal income tax regardless of the source or (4) a trust with respect
to which a court within the United States is able to exercise primary
supervision over your administration and one or more U.S. persons have the
authority to control all your substantial decisions. This summary is based on
the Internal Revenue Code, Treasury regulations, administrative rulings and
court decisions, all as in effect as of the date hereof and all of which are
subject to change at any time (possibly with retroactive effect). This summary
is not a complete description of all tax consequences of the merger and, in
particular, may not address U.S. federal income tax considerations applicable to
stockholders subject to special treatment under U.S. federal income tax law
(including, for example, stockholders who are not U.S. persons, financial
institutions, dealers in securities, insurance companies, tax-exempt entities,
holders who acquired NetOptix common stock pursuant to the exercise of an
employee stock option or right or otherwise as compensation, and holders who
hold NetOptix common stock as part of a hedge, straddle or conversion
transaction). In addition, no information is provided herein with respect to the
tax consequences of the merger under applicable foreign, state or local laws.

         The material U.S. federal income tax consequences of the merger are as
follows:

         -    the merger will constitute a reorganization within the meaning of
              Section 368 of the U.S. Internal Revenue Code;

         -    no gain or loss will be recognized by the holders of NetOptix
              common stock who exchange their NetOptix common stock for
              Corning common stock pursuant to the


                                      -41-
<PAGE>



              merger, except with respect to any cash received in lieu of a
              fractional share of Corning common stock;

         -    the aggregate tax basis of the Corning common stock received
              in the merger by each holder of NetOptix common stock will be
              the same as the aggregate tax basis of the NetOptix common
              stock surrendered in exchange therefor, reduced by any amount
              of tax basis allocable to a fractional share interest in
              Corning common stock for which cash is received;

         -    the holding period of a holder of NetOptix common stock for
              Corning common stock received in the merger will include the
              holding period for the NetOptix common stock surrendered in
              exchange therefor;

         -    an NetOptix stockholder who receives cash in lieu of a
              fractional share interest in Corning common stock pursuant to
              the merger will be treated as having received such cash in
              exchange for such fractional share interest and generally will
              recognize capital gain or loss on such deemed exchange in an
              amount equal to the difference between the amount of cash
              received and the tax basis of the NetOptix common stock
              allocable to such fractional share interest; and

         -    no gain or loss will be recognized by Corning, Corning
              shareholders, CI Subsidiary, Inc. or NetOptix as a result of the
              merger.

         Nixon Peabody LLP and Edwards & Angell, LLP have provided opinions,
filed as exhibits to the registration statement related to this Proxy
Statement/Prospectus, to Corning and NetOptix, respectively, to the effect that,
subject to limitations set forth herein, this summary describes the material
U.S. federal income tax consequences of the merger to holders of NetOptix common
stock. In addition, the obligations of the parties to consummate the merger are
conditioned upon the receipt by Corning of a further opinion from Nixon Peabody
LLP, or alternatively in the case of NetOptix, Edwards & Angell, LLP, in each
case subject to the qualifications discussed herein, confirming the
characterization of the merger as a "reorganization" within the meaning of
Section 368(a) of the Internal Revenue Code. Stockholders should be aware that
an opinion of counsel is not binding on the Internal Revenue Service or the
courts. Stockholders should also be aware that the opinions of Nixon Peabody LLP
and Edwards & Angell, LLP, filed as exhibits to the registration statement and
delivered at the time of the merger, are and will be based on current law and on
representations and assumptions regarding current and future factual matters and
covenants as to future actions made by Corning and NetOptix. If any of the
representations or assumptions is inaccurate or incorrect or any of the
covenants is not complied with, the conclusions stated in these opinions could
be affected.

         Under the U.S. backup withholding rules, you as a holder of NetOptix
common stock may be subject to backup withholding at the rate of 31% on any cash
received in lieu of fractional shares of Corning common stock, unless you (1)
are a corporation or come within other exempt categories and, when required,
demonstrate this fact or (2) provide a correct taxpayer identification number,
certify that you are not subject to backup withholding and otherwise comply with
applicable requirements of the backup withholding rules. Any amount withheld
under these rules will be credited against your federal income tax liability
provided you furnish the required information to the IRS. If you do not comply
with the backup withholding rules, you may be subject to penalties imposed by
the IRS.

         The preceding summary does not purport to be a complete analysis or
discussion of a potential tax effect relevant to the merger. You are urged to
consult with your own tax advisors regarding the U.S. federal income and other
tax consequences of the merger to you, under state, local and foreign tax laws.

                              ACCOUNTING TREATMENT

         Corning will account for the merger under the purchase method of
accounting in accordance with generally accepted accounting principles. The
purchase price will be allocated based on the fair value of the assets acquired
and the liabilities assumed. Any excess of the purchase price will be allocated
to goodwill and any acquired in-process research and development will be charged
to expense in the period in which the transaction closes.

                              REGULATORY APPROVALS

         HART-SCOTT-RODINO. The Federal Trade Commission and the Antitrust
Division of the Department of Justice frequently scrutinize the legality under
the antitrust laws of transactions such as the merger. At any time before or
after the merger, the Department of Justice or the Federal Trade Commission
could take such action under the antitrust laws as it deems necessary or
desirable in the public interest, including seeking to enjoin the merger or
seeking divestiture of substantial assets of Corning or NetOptix or their
subsidiaries. Private parties and state attorneys general may also bring an
action under the antitrust laws under certain circumstances. There can be no
assurance that a challenge to the merger on antitrust grounds will not be made
or, if such a challenge is made, of the result.

         On March 3, 2000, Corning and NetOptix filed Pre-Merger Notification
and Report forms with the Federal Trade Commission and the Department of Justice
under the Hart-Scott-Rodino Act and requested early termination of the
applicable waiting period. On April __, 2000, the waiting period will terminate.

         OTHER. Corning and NetOptix must obtain and keep in effect as a
condition to the consummation of the merger all material governmental consents,
approvals and authorizations legally required for the consummation of the merger
and the transactions contemplated by the merger. In addition, certain foreign
governmental filings are required to be made in connection with the merger.
Corning and NetOptix expect that none of them would prohibit consummation of the
merger. However, no assurance can be given that the required consents, approvals
or authorizations will be obtained.

                  RESTRICTIONS ON SALES OF CORNING COMMON STOCK

         All shares of Corning common stock received by NetOptix stockholders in
the merger will be freely transferable, except that shares of Corning common
stock received by persons who are affiliates of NetOptix at the effective time
of the merger or on the date of the special meeting may be resold by them only
in transactions:

         -    permitted by the resale provisions of Rule 145 promulgated under
              the Securities Act;

         -    permitted by Rule 144 promulgated under the Securities Act in the
              case of those persons who become affiliates of Corning after the
              effective time; or

         -    as otherwise permitted under the Securities Act.

         Affiliates of NetOptix are those individuals or entities that control,
are controlled by, or are under common control with NetOptix. Affiliates
generally include executive officers and directors of NetOptix as well as
certain principal stockholders of NetOptix. This proxy statement/prospectus does
not cover any resales of Corning common stock received by affiliates of NetOptix
in the merger.

                             STOCK EXCHANGE LISTING

         It is a condition to the merger that the shares of Corning common stock
to be issued pursuant to the merger agreement be authorized for listing on the
New York Stock Exchange, subject to official notice of issuance. An application
will be filed to list on the New York Stock Exchange the shares of Corning
common stock to be issued in the merger. Following the merger, NetOptix common
stock will no longer be registered under the Securities Exchange Act or traded
on the NASDAQ.

                               NO APPRAISAL RIGHTS

         Holders of NetOptix common stock are not entitled to appraisal rights
under Section 262 of the Delaware General Corporation Law in connection with the
merger.

                              THE MERGER AGREEMENT

         The following summary of the material terms and provisions of the
merger agreement is qualified in its entirety by reference to the merger
agreement, dated as of February 13, 2000, between Corning, CI Subsidiary, Inc.
and NetOptix. The merger agreement is attached as Appendix A to this proxy
statement/prospectus and is incorporated by reference herein.

CONVERSION OF SECURITIES

         At the effective time of the merger, each share of NetOptix common
stock issued and outstanding immediately prior to the effective time of the
merger will be converted into the right to receive 0.90 of a share of Corning
common stock. After the effective time of the merger, each certificate that
previously represented shares of NetOptix common stock will represent only the
right to receive the number of whole shares of Corning common stock into which
the shares of NetOptix common stock are converted in the merger and a payment of
cash instead of any fractional shares of Corning common stock.

EXCHANGE OF CERTIFICATES

         As soon as practicable after the effective time of the merger (but in
any event within five business days), Harris Trust and Savings Bank or another
bank or trust company designated by Corning and acceptable to NetOptix, in its
capacity as exchange agent, will send a transmittal letter to each former
NetOptix shareholder. The transmittal letter will contain instructions on how to
obtain shares of Corning common stock in exchange for shares of NetOptix common
stock. NETOPTIX STOCKHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES UNTIL
THEY RECEIVE THE TRANSMITTAL MATERIALS FROM THE EXCHANGE AGENT.

STOCK OPTIONS

         All NetOptix's stock options will remain outstanding to the extent not

NO SOLICITATION PROVISION

         NetOptix has agreed not to, directly or indirectly, solicit any
inquiries for any proposal or offer with respect to a business combination or
similar transaction or sale of assets which would compete with or interfere with
the merger, including any dissolution or similar transaction or any purchase or
sale of all or any significant portion of the assets or more than 10% of its
common stock or the assets or capital stock of any of its subsidiaries. NetOptix
has also agreed to cease and cause its agents and representatives to terminate
any discussions or negotiations with respect to any offer or proposal with
respect to an acquisition proposal. NetOptix has agreed to notify Corning
promptly, but in any event within two days, of all inquiries and proposals that
NetOptix may receive relating to any of the foregoing matters, such notice to
set out the terms and conditions of such inquiry or proposal and the identity of
the person making it.

         Notwithstanding the foregoing, prior to the adoption of the merger
agreement by the stockholders of NetOptix, the NetOptix board of directors is
not prohibited from:

         -    furnishing information to, or entering into and engaging in
              discussions or negotiations with, any person in response to an
              unsolicited written proposal or offer regarding an acquisition
              transaction; or

         -    recommending an acquisition proposal to the stockholders if
              the NetOptix board of directors determines in good faith that
              the acquisition proposal constitutes a superior proposal which
              would be materially more favorable to the holders of NetOptix
              common stock than the merger and is reasonably capable of
              being completed, in which case, the NetOptix board of
              directors may cause NetOptix to enter into an acquisition
              agreement as to the superior proposal so long as, among other
              conditions, NetOptix has terminated the merger agreement in
              accordance with its terms and paid the termination fee
              referenced under "Termination and Termination Fees".

         In addition, pursuant to the stockholder voting agreement and
irrevocable proxy, the principal stockholders of NetOptix, Andlinger Capital
XIII LLC, Mr. Andlinger, Mr. Magida, acting in his capacity as manager of
Andlinger Capital and as trustee of a trust for Mr. Andlinger, and Mr. Blais,
have agreed to vote their shares in favor of the merger and not to solicit other
offers, among other things. This agreement also has the effect of discouraging
other persons who may be interested in acquiring NetOptix.

                      above under "No Solicitation Provision";

                  -   prior to termination, NetOptix has negotiated with Corning
                      to make adjustments in the terms and conditions of the
                      merger agreement as would enable NetOptix to proceed with
                      the merger rather than the competing proposal;

                  -   the NetOptix board of directors shall have concluded in
                      good faith, after giving effect to the adjustments which
                      may be offered by Corning, that the competing proposal is

                  -   NetOptix shall have paid the termination fee to Corning as
                      provided in the merger agreement;

                      merger agreement;

               board of directors recommends to the NetOptix shareholders a
               superior proposal or NetOptix enters into negotiations with any
               person concerning a competing proposal in violation of the no

              NetOptix stockholders failing to adopt the merger agreement;

         -    a competing proposal for the acquisition of any of the
              outstanding shares of NetOptix or a substantial part of its
              business or properties had been made public or known to
              NetOptix

              the date of termination, there exists a competing proposal;

         -    following the existence of a competing proposal and prior to
              the date of termination, NetOptix shall have intentionally
              breached and not cured any of its material covenants or
              agreements set forth in the merger agreement in any material
              respect; and

         -    within 12 months of the termination of the merger agreement,
              NetOptix consummates or enters into an agreement with respect

         NetOptix will not be required to pay the termination fee if it has not
engaged in discussions or negotiations with, or provided confidential
information to, any person in respect of an acquisition proposal and the
NetOptix board of directors changes or withholds its recommendation of the
merger solely because it is required to do so by its fiduciary duties based on
other matters.

EXPENSES

         In the event of termination of the merger agreement by either Corning
or NetOptix, there shall be no liability on the part of NetOptix, Corning or CI

    NOTES TO UNAUDITED PRO FORMA COMBINED SUPPLEMENTAL FINANCIAL INFORMATION

(a)      On February 13, 2000, NetOptix agreed to be acquired by Corning in a
         merger transaction to be accounted for under the purchase method of
         accounting. The merger will be effected by Corning issuing shares and
         options at an exchange ratio of 0.90 for each share or right to
         aacquire shares of NetOptix common stock outstanding on the closing
         date. The actual number of shares of Corning common stock to be issued
         will depend on the actual number of shares of NetOptix common stock
         outstanding on the date the merger closes. This transaction is valued
         at approximately $2.1 billion based on the average closing price for a
         range of trading days (February 10 through February 16, 2000) around
         the announcement date (February 14, 2000) of the merger.

         The purchase price will be allocated based on the fair value of the
         assets acquired and the liabilities assumed. The excess of the purchase
         price over the assets acquired have been allocated to goodwill and
         other intangibles in this presentation. Corning currently expects the
         useful life of goodwill and other intangibles to range from seven to
         ten years. This pro forma presentation assumes a useful life of seven

         expensed in the period the transaction is completed. This presentation
         assumes no charge for in-process research and development.

(b)      Adjustments reflect the issuance of 12 million shares of Corning common
         stock to effect the exchange of NetOptix common stock , and options to
         acquire NetOptix common stock, at the exchange ratio of 0.90 of a share
         of Corning common stock for each share and option to acquire shares of
         NetOptix common stock.

         The pro forma combined per share amounts and weighted average common
         shares outstanding reflect the combined weighted average of Corning and
         NetOptix common shares outstanding for the period presented, after
         adjusting the number of NetOptix common shares to reflect the exchange
         ratio of 0.90 of a share of Corning common stock for each share of
         NetOptix common stock. The diluted unaudited pro forma per share
         information for Corning is based on the weighted average number of
         outstanding shares of Corning common stock adjusted to include (1) the
         dilutive effect of Corning employee stock options and (2) the number of
         shares of Corning common stock that would be issued in the merger. The
         effect of NetOptix employee stock options was not dilutive.

                                  THE COMPANIES

                                     CORNING

BUSINESS

         Corning traces its origins to a glass business established in 1851.
Corning 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.
Today, Corning is an international corporation competing in three broadly

                                    NETOPTIX

BUSINESS

         NetOptix was incorporated in Delaware in 1973 as the successor to a
business which was founded in 1959. NetOptix was named Galileo Corporation until
September, 1999, and as Galileo Electro-Optics Corporation from its
incorporation to September 1996. Since its incorporation, NetOptix has been
engaged in developing, manufacturing and marketing optical and fiberoptic and
electro-optic components which transmit, sense or intensify light or images and
a variety of components for office copiers.

         During 1999, NetOptix substantially restructured and reorganized its
business operations. NetOptix sold the businesses relating to medical products,
scientific detector and spectroscopy products and telecommunications products.
These businesses generated a majority of NetOptix's revenues and are treated as
discontinued operations in its financial statements. Currently, NetOptix along
with its wholly-owned subsidiaries, Optical Filter Corporation and Optical
Filter Corporation, GmbH, a German company


                                      -58-
<PAGE>

formed in 1999, develops, manufactures and markets systems that incorporate
recent advances in photonic technology and optical coating.

         NetOptix's business consists principally of the design, manufacture and
marketing of a broad range of optical components and systems, including optical
filters, optical lens coatings for medical devices, laser systems, infrared
thermal imaging devices and optical analytic instruments, as well as one of the
world's largest and most technically advanced diamond point turning facilities,
which manufactures highly sophisticated optical components and systems for
industrial lasers and semiconductor instrumentation. Beginning in 1999, NetOptix
developed and readied for commercial production optical filters for use in Dense
Wavelength Division Multiplexing (DWDM) components of fiberoptic networks
serving the telecommunications industry.

         The DWDM filters produced by NetOptix are capable, within certain
portions of the light wave spectrum, of dividing a light wave traveling through
a fiberoptic network into many separate beams of light, each capable of carrying
traffic over the network. NetOptix believes that there is a large and growing
marketplace for DWDM filters. Commercial production of DWDM filters began in
Fall 1999 and has continued in 2000, with commercial shipments commencing in
2000. Commencing in the second half of 1999, NetOptix added and has continued to
add substantial production capacity for its DWDM filter business at its facility
in Natick, Massachusetts, and organized Optical Filter Corporation, GmbH in
Germany, which is in the process of completing a facility in Waechtersbach,
Germany for optical filter technology research and development as well as
commercial production of DWDM filters. The German facility began commercial
production and shipments in 2000. NetOptix expects to continue to expand its
production capacity at its facilities in Natick, Massachusetts and in Germany
during 2000.

         NetOptix's operations also include a facility in Keene, New Hampshire,
which provides products and services for diamond point turning for highly
sophisticated optical components and systems for industrial lasers and for
semiconductor instrumentation.

         Additional information concerning NetOptix is included in NetOptix's
reports filed under the Securities Exchange Act that are incorporated by
reference in this proxy statement/prospectus. See "Where You Can Find More

                      DESCRIPTION OF CORNING CAPITAL STOCK

AUTHORIZED CAPITAL STOCK

         Corning's authorized capital stock consists of 500,000,000 shares of
common stock, $.50 par value, and 10,000,000 shares of preferred stock, $100 par
value. The board of directors of Corning is recommending approval by Corning
shareholders at their April 27, 2000 annual meeting of an amendment to Corning's
Restated Certificate of Incorporation to increase the number of authorized
shares of common stock from 500,000,000 to 1,200,000,000.

COMMON STOCK

         As of March 6, 2000, there were 277,077,201 outstanding shares of
Corning common stock held by approximately 17,500 holders of record. The holders
of Corning common stock are entitled to one vote for each share on all matters
submitted to a vote of stockholders and do not have cumulative voting rights.
The Corning board of directors is classified into three classes of approximately
equal size, one of which is elected each year. Accordingly, holders of a
majority of the Corning common stock entitled to vote in any election of
directors may elect all of the directors standing for election. The holders of
Corning common stock are entitled to share ratably in all assets of Corning
which are legally available for distribution, after payment of all debts and
other liabilities and subject to the prior rights of any holders of Corning
preferred stock then outstanding. The current quarterly cash dividend of Corning
common stock is $0.18 per share of common stock. The continued declaration of
dividends by the Corning board of directors is subject to the current and
prospective earnings, financial condition and capital requirements of Corning
and any other factors that the Corning board of directors deems relevant. The
holders of Corning common stock have no preemptive, subscription, redemption or
conversion rights. The outstanding shares of Corning common stock are fully paid
and nonassessable. The rights, preferences and privileges of holders of Corning
common stock are subject to the rights of the holders of shares of any series of
Corning preferred stock which Corning may issue in the future.

PREFERRED STOCK

         Corning has designated 2,400,000 shares of its preferred stock as
Series A junior participated preferred stock, 316,822 shares as Series B
convertible preferred stock and 4,683,710 shares as Series C 6% cumulative
convertible preferred stock. As of March 6, 2000, there were 104,825 outstanding
shares of Series B preferred stock, held exclusively by the trustee of Corning's
existing employee investment plans. No other Corning preferred stock is
outstanding. Series A preferred stock is reserved for issuance upon exercise of
the rights distributed to the holders of Corning common stock pursuant to the
Corning rights agreement referred to below.

         The Corning board of directors has the authority, without further
shareholder approval, to create other series of preferred stock, to issue shares
of preferred stock in such series up to the maximum number of shares of the
relevant class of preferred stock authorized, and to fix the dividend rights and
terms, conversion rights and terms, voting rights, redemption rights and terms,
liquidation preferences, sinking funds and any other rights, preferences and
limitations applicable to each such series of Corning preferred stock. The
purpose of authorizing the Corning board of directors to determine such rights
and preferences is to eliminate delays associated with a stockholder vote on
specific issuances. The issuance of Corning preferred stock, while providing
flexibility in connection with possible acquisitions and other corporate
purposes, could, among other things, adversely affect the voting power of
holders of Corning common stock and, under certain circumstances, make it more
difficult for a third party to gain control of Corning.


RIGHTS AGREEMENT

                                      -60-
<PAGE>

         Corning has adopted a Rights Agreement, dated as of June 5, 1996, which
provides for the issuance of one right to the holder of each share of Corning
common stock. Ten days after any person or group acquires or announces its
intention to acquire 20% or more of the outstanding Corning stock, each Corning
right will entitle the holder, other than the acquiring person or group, to
purchase one one-hundredth of a share of Series A preferred stock, at an
exercise price of $125 subject to certain antidilution adjustments.

         If a person or group announces its intention to acquire 20% or more of
the outstanding Corning common stock or if Corning is acquired in a merger or
other business combination or sells 50% or more of its assets or earning power,
each Corning right, other than a Corning right beneficially owned by the
acquiring person or group, which will be void, will entitle the holder to
purchase, at the exercise price, common stock of the acquiring person or group
having a current market value of two times the exercise price of the right.
Prior to a person or group acquiring 50% or more of the outstanding Corning
common stock, the Corning board of directors may also elect to issue a share of
Corning common stock in exchange for each Corning right, other than Corning
rights held by the acquiring person or group.

         The Corning rights expire on July 15, 2006, unless this expiration date
is extended or the Corning rights are exchanged or redeemed by Corning before
such date. Prior to an announcement by a person or group of its intent to
acquire 20% or more of the outstanding Corning common stock, Corning may redeem
the Corning rights in whole, but not in part, for $0.01 per Corning right, or it
may amend the Corning rights agreement in any way without the consent of the
holders of the Corning rights.

INDEMNIFICATION AND LIABILITY OF DIRECTORS AND OFFICERS

         Sections 722 and 723 of the Business Corporation Law of the State of
New York provide that a corporation may indemnify its current and former
directors and officers under certain circumstances. Corning's bylaws provide
that it shall indemnify each director and officer against all costs and expenses
actually and reasonably incurred by him in connection with the defense of any
action or proceeding against him or related appeal by reason of his being or
having been a director or officer of Corning to the full extent permitted by the
Business Corporation Law.

         Section 402(b) of the Business Corporation Law provides that a
corporation may include a provision in its certificate of incorporation limiting
the liability of its directors to the corporation or its shareholders for
damages for the breach of any duty, except for a breach involving intentional
misconduct, bad faith, a knowing violation of law or receipt of an improper
personal benefit or for certain illegal dividends, loans or stock repurchases.
Corning's restated certificate of incorporation provides that its directors'
liability is limited to the extent permitted by the Business Corporation Law.

TRANSFER AGENT AND REGISTRAR

         The transfer agent and registrar for the Corning common stock is Harris
Trust and Savings Bank in Chicago, Illinois. Harris Trust has advised Corning
that it is selling its shareholder services business to Computershare Limited.

                        COMPARISON OF STOCKHOLDER RIGHTS

         As a result of the merger, holders of NetOptix common stock will become
holders of Corning common stock. The following is a summary of certain of the
material differences between the rights of holders of NetOptix common stock and
the rights of holders of Corning common stock. Corning is organized under the
laws of the State of New York, and NetOptix is organized under the laws of the
State of Delaware. These differences arise from differences between the New York
and Delaware state laws, as


                                      -61-
<PAGE>

well as under the various provisions of the Corning restated certificate of
incorporation and bylaws and the NetOptix restated certificate of incorporation,
as amended, and bylaws.

         The following summary does not purport to be a complete statement of
the rights of holders of Corning common stock and NetOptix common stock under,
and is qualified by its entirety by reference to, New York law, Delaware law and
the charters and bylaws of Corning and NetOptix. See "Description of Corning
Capital Stock" on pages __ through ___ for a summary of certain other rights
relating to the Corning common stock.

NUMBER, CLASSIFICATION AND REMOVAL OF DIRECTORS

         The number of directors of Corning is fixed by the Corning board of
directors and, unless approved by at least two-thirds of the Corning board of
directors, or 80% of the holders of shares then entitled to vote in the election
of directors, shall be not less than nine nor more than twenty-four. The Corning
board of directors is divided into three classes serving staggered three-year
terms and any one or more of the directors of Corning may be removed from office
at any time, but only for cause, and only by the holders of at least a majority
of the shares then entitled to vote in an election of directors or a majority of
the Corning board of directors.

         The number of directors of NetOptix is fixed by the NetOptix board of
directors and shall not be fewer than three nor more than nine. Directors serve
until the next annual meeting of stockholders or until their successors are
elected and qualified. Delaware law provides that, except with respect to
corporations with classified boards or cumulative voting, a director may be
removed, with or without cause, by the holders of the majority in voting power
of the shares entitled to vote at an election of directors. NetOptix's board of
directors is not classified and there is no cumulative voting.

ADVANCE NOTICE OF STOCKHOLDER PROPOSALS

         The bylaws of Corning provide that a stockholder must give advance
written notice if the stockholder intends to make nominations for the Corning
board of directors. They do not provide for other stockholder proposals. For a
director nomination to be properly brought by a stockholder before an annual
meeting, notice must be delivered to or mailed by the stockholder and received
at the principal executive offices of Corning not less than 90 days, nor more
than 120 days prior to the anniversary of the prior year's annual meeting;
provided, however, that if the date of the annual meeting has been advanced by
more than 30 days or delayed by more than 60 days from such anniversary date,
the stockholder's notice must be received no earlier than 120 days prior to such
meeting and at least 90 days prior to the annual meeting or the tenth day
following the day on which public announcement of the date of such meeting is
first made.

         To be timely with respect to a director nomination at a special meeting
of Corning's stockholders, a stockholder's notice must be delivered to or mailed
by the stockholder and received by Corning at least 90 days prior to the date of
the meeting or the tenth day following the day on which public announcement of
the date of such meeting is first made, and no earlier than 120 days prior to
the date of the meeting.

         NetOptix's bylaws do not provide for advanced notice with respect to
stockholder proposals.

                                      -62-
<PAGE>

RIGHT TO CALL SPECIAL MEETINGS

         The bylaws of Corning provide that special meetings of stockholders may
be called at any time by the Chairman, the Chairman of the Executive Committee,
a Vice-Chairman or the President.

         Special meetings of the stockholders of a Delaware corporation may be
called by the board of directors or by the persons authorized in the
corporation's certificate of incorporation or bylaws. NetOptix's bylaws provide
that a special meeting of the stockholders may be called at any time by the
President, and shall be called by the President or Secretary at the request of a
majority of the board of directors or at the request of stockholders owning a
majority of the outstanding capital stock of NetOptix.

SHAREHOLDER ACTION BY WRITTEN CONSENT

         Under New York law, any action which may be taken at a meeting of
shareholders of Corning may also be taken by the written consent of all the
holders entitled to vote thereon.

         NetOptix's bylaws provide that any action required to be taken or which
may be taken at any annual or special meeting of stockholders may be taken
without a meeting, if a consent in writing, setting forth the action so taken,
shall be signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote were present and voted.

TRANSACTIONS WITH INTERESTED SHAREHOLDERS

         Corning is subject to Section 912 of the New York Business Corporation
Law. Under Section 912, an interested shareholder, defined generally as a person
owning 20% or more of a corporation's outstanding voting stock, is prevented
from engaging in a business combination with the corporation for five years
after becoming an interested shareholder unless:

         -    the board approved the transaction in which the interested
              shareholder became an interested shareholder; or

         -    the board approves the business combination before the shareholder
              becomes an interested shareholder.

         NetOptix is subject to Section 203 of the Delaware General Corporation
Law. Under Section 203, an interested stockholder, defined generally as a person
owning 15% or more of a corporation's outstanding voting stock, is prevented
from engaging in a business combination with the corporation for three years
after becoming an interested stockholder unless:

         -    the board approved the transaction in which the interested
              stockholder became an interested stockholder;

         -    the interested stockholder owns at least 85% of the voting stock
              upon consummation of the transaction in which the stockholder
              became interested; or

         -    the board approves the business combination and 2/3 of the
              outstanding voting stock of the corporation not owned by the
              interested stockholder approves the business combination.

<PAGE>


AMENDMENT OF CHARTER AND BYLAWS

         In general, the Corning certificate of incorporation may be amended by
an affirmative vote of the Corning board of directors and the holders of a
majority of Corning's shares. Any amendment to the article of the Corning
certificate of incorporation which relates to approval of a business
combination, however, requires the affirmative vote of 80% of the outstanding
voting stock of Corning unless it has been approved by a vote of 66 2/3% of the
full Corning board of directors and an affirmative vote of a majority of
continuing members of the Corning board of directors. In addition, any amendment
to the article which relates to the Corning board of directors, requires the
affirmative vote of 80% of the outstanding voting stock of Corning unless it had
been approved by a vote of 66 2/3% of the full Corning board of directors. Under
New York law, a corporation's bylaws may be amended by a majority of the votes
of shares then entitled to vote in the election of directors or, when so
provided in the corporation's certificate of incorporation or bylaws, by the
board of directors. Under the Corning bylaws, a bylaw may be amended by the
affirmative vote of a majority of the full Corning board of directors or the
holders of a majority of Corning's voting stock, other than the article relating
to the Corning board of directors which requires the affirmative vote of 80% of
the outstanding shares of Corning unless they have been approved by a vote of 66
2/3% of the full Corning board of directors.

         A Delaware corporation's certificate of incorporation generally may be
amended by a majority in voting power of the outstanding stock entitled to vote,
unless the corporation's certificate of incorporation provides for a greater
vote. The NetOptix certificate of incorporation does not provide for a greater
vote.

         Delaware vests the power to amend a company's bylaws in the
stockholders unless a company's certificate of incorporation confers such power
upon the directors. The NetOptix certificate of incorporation authorizes the
board of directors to amend the bylaws provided that such amendment is
consistent with Delaware law. The NetOptix bylaws permit either the stockholders
or the board of directors to amend the bylaws or adopt new bylaws. Conferring
such power on the directors, however, will not divest the stockholders of such
power.

promulgated thereunder (the "Code"); and

         WHEREAS, contemporaneously with the execution and delivery of this

Time, until the earlier of their respective deaths, resignations, and the time

                                   ARTICLE III

                              CONVERSION OF SHARES

         Section 3.1 Merger Consideration. As of the Effective Time, by virtue
of the Merger and without any action on the part of any stockholder of the
Company or Merger Subsidiary:

                  (a) Each share of common stock, par value $.01 per share, of
Merger Subsidiary (the "Merger Subsidiary Common Stock") that is issued and
outstanding immediately prior to the Effective Time shall be converted into one
fully paid and nonassessable share of common stock, par value $.01 per share, of
the Surviving Corporation.

                  (b) Each share of the common stock of the Company, par value
$.01 ("Company Common Stock") that is owned by the Company as treasury stock and
any shares of the Company Common Stock that are owned by Buyer or by its
subsidiaries shall be canceled and shall cease to exist, and no stock of Buyer
or other consideration shall be delivered in exchange therefor.

                  (c) Subject to the provisions of this Section 3.1, each share
of the Company Common Stock, other than Dissenting Shares (as defined below) and
shares canceled pursuant to Section 3.1(b), issued and outstanding immediately
prior to the Effective Time shall by virtue of the Merger and without any action
on the part of the holder thereof, be converted into the right to receive a
number of validly issued, fully paid and nonassessable shares of Common Stock,
par value $.50 per share, of Buyer ("Buyer Common Stock") equal to 0.9 share of
Buyer Common Stock (the "Merger Consideration"). The "Exchange Ratio" shall be
equal to 0.9.

                  (d) If at any time during the period between the date of this
Agreement and the Effective Time, the Company changes the number of shares of
the Company Common Stock outstanding, or Buyer changes the number of shares of
Buyer Common Stock, issued and outstanding as a result of a stock split, reverse
stock split, stock dividend, recapitalization, redenomination of share capital
or other similar transactions, the Exchange Ratio and any other items dependent
thereon shall be appropriately adjusted.

                  (e) Each outstanding share of the Company Common Stock the
holder of which has perfected his right to dissent under applicable law and has
not effectively withdrawn or lost such right as of the Effective Time (the
"Dissenting Shares") shall not be converted into or represent a right to receive
the Merger Consideration, and the holder thereof shall be entitled only to such
rights as are granted by applicable law; provided, however, that any Dissenting
Share held by a person at the Effective Time who shall,

<PAGE>
                                      -4-


after the Effective Time, withdraw the demand for payment for shares or lose the
right to payment for shares, in either case pursuant to the Delaware Law, shall
be deemed to be converted into, as of the Effective Time the Merger
Consideration. The Company shall give Buyer prompt notice upon receipt by the
Company of any such written demands for payment of the fair value of such shares
of the Company Common Stock and of withdrawals of such notice and any other
instruments provided pursuant to applicable law. Any payments made in respect of
Dissenting Shares shall be made by the Surviving Corporation.

                  (f) Pursuant to the terms of the plans pursuant to which the
Company Stock Options and ESPP Options (each as defined below) were issued and
this Agreement, the outstanding and unexercised Company Stock Options and ESPP
Options and the Andlinger Capital Warrant shall, at the Effective Time, become
rights to acquire shares of Buyer Common Stock in accordance with their terms
except that the number of shares of Buyer Common Stock subject to such Options
or Warrant shall be equal to the product of the (i) number of shares of the
Company Common Stock subject to the original Option or Warrant, and (ii) the
Exchange Ratio, and the exercise price per share of Buyer Common Stock under
such Option or Warrant shall be equal to: (iii) the exercise price under the
Option as written divided by (iv) the Exchange Ratio. The adjustments provided
herein with respect to any Options which are "incentive stock options" (as
defined in Section 422 of the Code) shall be effected in a manner consistent
with Section 424(a) of the Code.

         3.2 Stockholders' Rights at the Effective Time. On and after the
Effective Time, the certificates that immediately prior to the Effective Time
represented shares of the Company Common Stock (the "Certificates") shall cease
to represent any rights with respect to the Company and shall only represent the
right to receive the Merger Consideration, together with the amount of cash, if
any, payable in lieu of fractional shares of Buyer Common Stock into which any
shares of the Company Common Stock have been converted, provided, however, that
no dividends or other distributions, if any, in respect of the shares of Buyer
Common Stock, declared after the Effective Time and payable to holders of record
after the Effective Time, shall be paid to the holders of any unsurrendered
Certificates until such Certificates and transmittal letters are surrendered and
delivered as provided in Section 3.3 of this Agreement. Subject to applicable
Delaware Law, after the surrender and exchange of Certificates, the record
holders thereof will be entitled to receive any such dividends or other
distributions declared after the Effective Time without interest thereon, which
theretofore have become payable with respect to the number of shares of Buyer
Common Stock for which such Certificates were exchangeable. Notwithstanding
anything herein to the contrary, holders of any unsurrendered Certificates shall
not be entitled to exercise any rights as a holder of Buyer Common Stock,
including, without limitation, the right to vote the Buyer Common Stock, until
such Certificates are surrendered and exchanged pursuant to this Agreement.

         3.3 Surrender and Exchange of Share Certificates.

                  (a) Promptly after the Effective Time, Buyer shall make
available to Harris Trust, (the "Paying Agent") such certificates evidencing
such number of shares of

<PAGE>
                                      -5-

Buyer Common Stock to enable the Paying Agent to effect the conversion of the
Company Common Stock into shares of Buyer Common Stock as provided in Section
3.3(b) and an amount of cash as shall be reasonably estimated as needed to make
payments in lieu of fractional shares. Notwithstanding any other provision of
this Agreement, no fractional shares of Buyer Common Stock will be issued, and
any holder of Company Common Stock entitled to receive a fractional share of
Buyer Common Stock but for this Section 3.3(a) shall be entitled to receive a
cash payment in lieu thereof, which payment shall represent such holder's
proportionate interest in a share of Buyer Common Stock.

                  (b) On the Closing Date, Buyer shall instruct the Paying Agent
to mail to each person who was a holder of record of shares of the Company
Common Stock immediately prior to the Effective Time: (i) a letter of
transmittal, and (ii) instructions for use in effecting the surrender of the
Certificates nominally representing the Company Common Stock in exchange for
certificates representing the Buyer Common Stock determined in accordance with
the Exchange Ratio and/or cash in lieu of fractional shares.

                  (c) After the Effective Time, each holder of a Certificate
shall surrender and deliver such Certificate to the Paying Agent together with a
duly completed and executed transmittal letter. Upon such surrender and
delivery, the holder shall receive a certificate representing the number of
whole shares of Buyer Common Stock for which such holder's shares of the Company
Common Stock have been converted, together with a check for any cash in lieu of
any fractional share of Buyer Common Stock. Until so surrendered and exchanged,
each Certificate formerly representing an outstanding share of the Company
Common Stock shall after the Effective Time be deemed for all purposes to
evidence only the right to receive the Merger Consideration as provided in
Section 3.1, together with cash in lieu of any fractional share of Buyer Common
Stock.

                  (d) At the Effective Time, the stock transfer books of the
Company shall be closed and no transfer of shares of the Company Common Stock
shall be made thereafter, other than transfers of shares of the Company Common
Stock that have occurred prior to the Effective Time. In the event that, after
the Effective Time, certificates are presented for transfer to the transfer
agent for the Company, the Merger Subsidiary or Buyer, they shall be delivered
to the Paying Agent and exchanged for shares of Buyer Common Stock and any cash
payable in lieu of fractional shares thereof all as provided for in this Section
3.3.

                  (e) Any shares of Buyer Common Stock that remain undistributed
to the stockholders of the Company as of the Effective Time for a period of four
months after the Effective Time shall be delivered to Buyer by the Paying Agent,
upon demand, and any former stockholders of the Company who have not previously
complied with this Section 3.3 shall thereafter look only to Buyer for payment
of their claim for Buyer Common Stock and any dividends or distributions with
respect to Buyer Common Stock or cash in lieu of fractional shares.


<PAGE>
                                      -6-


                  (f) Neither the Paying Agent, nor any of the Company, Merger
Subsidiary or Buyer shall be liable to any holder of shares of the Company
Common Stock with respect to any shares of Buyer Common Stock (or dividends or
distributions with respect to Buyer Common Stock) delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law, rule,
regulation, statute, order, judgment or decree.

                  (g) In the event any Certificates shall have been lost, stolen
or destroyed, the Paying Agent shall issue such shares of Buyer Common Stock and
any dividends or other distributions with respect to Buyer Common Stock to which
such holder is entitled in exchange for such lost, stolen or destroyed
Certificates, upon the making of an affidavit of that fact by the holder thereof
and the delivery of such bond as the Paying Agent may reasonably require.

                  (h) No transfer taxes shall be payable by any stockholder of
the Company in respect of the issuance of the Buyer Common Stock under this
Section 3.3, except that if any Buyer Common Stock is to be issued in a name
other than that in which the Certificate surrendered has been registered, it
shall be a condition of such issuance that the person requesting such issuance
shall pay to Buyer any transfer taxes payable by reason thereof, or of any prior
transfer of such surrendered certificate, or establish to the satisfaction of
Buyer that such taxes have been paid or are not payable.

         Section 3.4 No Further Rights. From and after the Effective Time,
holders of certificates theretofore evidencing shares of the Company Common
Stock shall cease to have any rights as stockholders of the Company, except as
provided herein or by law.

                                   ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Disclosure Schedule"):

is now being conducted and is duly qualified or licensed to do business, and is
in good standing, in each jurisdiction where the character of its properties
owned or held under lease or the nature of its activities makes such
qualification necessary, except where the failure to be so organized, qualified
or in good standing, or have such power or authority when taken together with
all other such failures, is not reasonably likely to have a Company Material
Adverse Effect (as defined below). The Company has heretofore made available to
Buyer and Merger Subsidiary a

lease, license, permit, franchise or other instrument or obligation to which the
Company or any of its Subsidiaries is a party or by which the Company or any of
its Subsidiaries or any property or asset of the Company or any of its
Subsidiaries is bound or affected, except in the case of clause (iii) for any
such conflicts, violations, breaches, defaults or other occurrences of the type

would not prevent or materially delay the consummation of the Merger.

                  (b) The execution and delivery of this Agreement or the
Related Agreement by the Company does not, and the performance of this Agreement
by the Company will not, require any consent, approval, authorization, waiver or

                                      -9-

have a Company Material Adverse Effect or would not prevent or materially delay
the consummation of the Merger.

         Section 4.5 Reports and Financial Statements.

                  (a) The Company has filed with the U.S. Securities and
Exchange Commission ("SEC") all forms, reports, schedules, registration
statements, definitive proxy statements and information statement or other
filings (the "Company SEC Reports") required to be filed by it with the SEC
since September 30, 1997. As of their respective dates, the Company SEC Reports
complied as to form in all material respects with the requirements of the
Exchange Act or the Securities Act, as the case may be, and the rules and
regulations of the SEC thereunder applicable to the Company SEC Reports. As of
their respective dates and as of the date any information from the Company SEC
Reports has been incorporated by reference, the Company SEC Reports did not
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading. The
Company has filed all material contracts and agreements and other documents or
instruments required to be filed as exhibits to the Company SEC Reports.

                  (b) The consolidated balance sheets of the Company as of
September 30, 1999 and 1998 and the related consolidated statements of
operations, stockholders' equity and cash flows for each of the three years in
the period ended September 30, 1999 (including the related notes and schedules
thereto) contained in the Company's Form 10-K for the year ended September 30,
1999 (the "Company Financial Statements") present fairly, in all material
respects, the consolidated financial position and the consolidated results of
operations, retained earnings and cash flows of the Company and its consolidated
Subsidiaries as of the dates or for the periods presented therein in conformity
with United States generally accepted accounting principles ("GAAP") applied on
a consistent basis during the periods involved except as otherwise noted
therein, including in the related notes.

                  (c) The consolidated balance sheets and the related statements
of operations and cash flows (including, in each case, the related notes
thereto) of the Company contained in the Form 10-Q for the quarterly period
ended December 31, 1999 (the "Company Quarterly Financial Statements") have been
prepared in accordance with the requirements for interim financial statements
contained in Regulation S-X, which do not require all the information and
footnotes necessary for a fair presentation of financial position, results of
operations and cash flows in conformity with GAAP. The Company Quarterly
Financial Statements reflect all adjustments necessary to present fairly in
accordance with GAAP (except as indicated), in all material respects, the
consolidated financial position, results of operations and cash flows of the
Company for all periods presented therein.

                  (d) Except for those liabilities that are fully reflected or
reserved against on the Company Financial Statements, the Company Quarterly
Financial Statements or as set forth in the Company Disclosure Schedule, neither
the Company nor


<PAGE>

                                      -10-

any Subsidiary has outstanding any liability of any nature whatsoever (whether
absolute, accrued, contingent (including any contingent liabilities or
obligations arising out of or relating to any sale of assets outside the
ordinary course of business, stock of any subsidiary, business or of any line of
business, or otherwise and whether due or to become due), except for liabilities
and obligations, which have been incurred since the date of the most recent
balance sheet contained in the Company Quarterly Financial Statements in the
ordinary course of business and which would not reasonably be likely,
individually or in the aggregate, to have a Company Material Adverse Effect or
which are described in the Company Disclosure Schedule.

                  (e) From the date of the most recent balance sheet contained
in the Company Financial Statements through the date hereof, except as set forth
in the Company Disclosure Schedule: (i) each of the Company and its Subsidiaries
has conducted its business only in the ordinary course and in a manner
consistent with past practice and (ii) there has, not been any circumstance,
event, occurrence, change or effect that has had or would reasonably be likely
to have, individually or in the aggregate, a Company Material Adverse Effect.

         Section 4.6 Information.

                  (a) None of the written information supplied or to be supplied
by the Company for inclusion or incorporation by reference in the definitive
Prospectus/Proxy Statement will, at the time of filing with the SEC, at the time
of the mailing of the Prospectus/Proxy Statement or any amendments or
supplements thereto to the Company's stockholders or at the time of the Company
Special Meeting, contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they are
made, not misleading. The portion of the Prospectus/Proxy Statement based on
information supplied by the Company for inclusion or incorporation by reference
therein will comply as to form in all material respects with the applicable
provisions of the Securities Act and the Exchange Act and the rules and
regulations thereunder.

                  (b) As of the date of this Agreement, the Company does not
know of any reason (i) for which it would not be able to deliver to both of
counsel to Buyer and the Company, at the date of the legal opinions referred to
below, certificates substantially in compliance with IRS published advance
ruling guidelines, with customary exceptions and modifications thereto, to
enable such firms to deliver the legal opinions contemplated by Section 8.2(c),
and the Company hereby agrees to deliver such certificates effective as of the
date of such opinions so long as the statements therein are true as of such time
or (ii) for which counsel to Buyer and the Company would not be able to deliver
the opinions required by Section 8.2(c).

         Section 4.7 Litigation. Except as disclosed in the Company SEC Reports
or on the Company Disclosure Schedule, as of the date hereof, there is no civil,
criminal or administrative suit, action or proceeding pending or, to the
knowledge of the Company, threatened against or affecting the Company or any of
its Subsidiaries that is reasonably

<PAGE>
                                      -11-

expected to have a Company Material Adverse Effect, nor is there any judgment,
decree, injunction or order of any Governmental Entity or arbitrator outstanding
against the Company or any of its Subsidiaries having, or which is reasonably
expected to have, individually or in the aggregate, a Company Material Adverse
Effect.

         Section 4.8 Absence of Certain Changes or Events. Except as disclosed
in the Company SEC Reports or as contemplated by this Agreement, since December
31, 1999, the Company has conducted its business only in the ordinary course,
and there has not been: (i) any change in the financial condition, properties,
business or results of operations of the Company and its Subsidiaries or any
development or combination of developments of which management of the Company
has knowledge that, individually or in the aggregate, has had or is reasonably
likely to have a Company Material Adverse Effect, (ii) any declaration, setting
aside or payment of any dividend or other distribution (whether in cash, stock
or property) with respect to any of the Company's capital stock, or, any
redemption, purchase or other acquisition of any of its capital stock, (iii) any
split, combination or reclassification of any of the Company's capital stock or,
except with respect to the Company Stock Options, the ESPP Options, and the
Andlinger Capital Warrants, any issuance or the authorization of any issuance of
any other securities in respect of, in lieu of or in substitution for shares of
the Company's capital stock, (iv) except as set forth in the Company Disclosure
Schedule, any granting by the Company or any of its Subsidiaries to any officer
of the Company of any increase in compensation or any rights with respect to
compensation in the event of a "change in control" (however defined) of the
Company, except in the ordinary course of business consistent with prior
practice or as required under employment agreements in effect as of December 31,
1999, (v) except as set forth in the Company Disclosure Schedule, any granting
by the Company or any of its Subsidiaries to any officer or any group or class
of employees of the Company of any increase in severance or termination pay,
except as required under employment, severance or termination agreements or
plans in effect as of December 31, 1999, (vi) except as set forth in the Company
Disclosure Schedule, any entry by the Company or any of its Subsidiaries into
any employment, severance or termination agreement with any officer of the
Company, or any increase in benefits available under or establishment of any the
Company Benefit Plan (as defined below) except in the ordinary course of
business consistent with past practice, or (vii) any material change in
accounting methods, principles or practices by the Company, except insofar as
may have been required by a change in GAAP.

         Section 4.9 Employee Benefit Plans.

                  (a) Schedule 4.9 sets forth a complete and correct list of all
"employee benefit plans", as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), and any other pension plans
or employee benefit arrangements or payroll practices (including, without
limitation, severance pay, vacation pay, company awards, salary continuation for
disability, sick leave, deferred compensation, bonus or other incentive
compensation, stock option or stock purchase arrangements or policies)
maintained, or contributed to, by the Company, its Subsidiaries or any trade or
business (whether or not incorporated) which is treated with the Company or its
Subsidiaries as a single employer under Section 414(b), (c), (m) or (o) of the
Code


<PAGE>
                                      -12-

("ERISA Affiliate") with respect to employees of the Company, its Subsidiaries
or their ERISA Affiliates (the "Company Benefit Plans"). Each Plan is in writing
and the Company has furnished or will furnish Buyer with a true and complete
copy of each Plan document, including all amendments thereto, and a true and
complete copy of each material document prepared in connection with each such
Plan, including, without limitation, (i) a copy of each trust or other funding
arrangement, (ii) each summary plan description and summary of material
modifications, (iii) the three most recently filed Form 5500's, including all
attachments thereto, (iv) the most recently received Internal Revenue Service
("IRS") determination letter for each such Plan, and (v) the most recently
prepared actuarial report and financial statement in connection with each such
Plan. Neither the Company nor its Subsidiaries have any express or implied
commitment (x) to create or incur liability with respect to or cause to exist
any other employee benefit plan, program or arrangement, (y) to enter into any
contract or agreement to provide compensation or benefits to any individual or
(z) to modify, change or terminate any Plan, other than with respect to a
modification, change or termination required by ERISA or the Code.

                  (b) No "accumulated funding deficiency" as defined in Section
412 of the Code exits with respect to any such Plan, whether or not waived. No
"reportable event" within the meaning of Section 4043 of ERISA, and no event
described in Section 4062 or 4063 of ERISA has occurred with respect to any
Plan. Neither the Company nor any ERISA Affiliate of the Company has: (i)
engaged in, or is a successor corporation or parent corporation to an entity
that has engaged in, a transaction described in sections 4069 or 4212(c) of
ERISA or (ii) incurred or reasonably expects to incur (A) any liability under
Title IV of ERISA arising in connection with the termination of, or a complete
or partial withdrawal from, any plan covered or previously covered by Title IV
of ERISA, or (B) any liability under Section 4971 of the Code that in either
case could become a liability of Surviving Corporation or Buyer or any of its
Affiliates after the Effective Time. As of September 30, 1999, the fair market
value of the assets of the Company's pension plan, excluding any accrued but
unpaid contributions, exceeded the present value of all benefits accrued under
such pension plan determined on a termination basis using the assumptions
established by the PBGC as in effect on such date. As of September 30, 1999,
there was no unfunded liability under any of the Plans, computed using
reasonable actuarial assumptions and determined as if all benefits under such
Plans were vested and payable as of such date. No event has occurred since
September 30, 1999 which would cause the Company to believe that as of the date
of this Agreement there is any such unfunded liability.

                  (c) Each of the Company Benefit Plans intended to qualify
under Section 401(a) of the Code ("Qualified Plans") has received a favorable
determination letter from the Internal Revenue Service that such Plan is so
qualified, and, except as disclosed on Company Disclosure Schedule, nothing has
occurred with respect to the operation of any such Plan which, either
individually or in the aggregate, would cause the loss of such qualification or
the imposition of any material liability, penalty or tax under ERISA or the
Code.


<PAGE>
                                      -13-

                  (d) Except as set forth in the Company Disclosure Schedule,
there has been no prohibited transaction (within the meaning of Section 406 of
ERISA or Section 4975 of the Code) with respect to any Company Benefit Plan.
Neither the Company nor any Subsidiary is currently liable or has previously
incurred any liability for any tax or penalty arising under Section 4971, 4972,
4975, 4979, 4980 or 4980B of the Code or Section 502 of ERISA, and no fact or
event exists which could give rise to any such liability which would have a
Company Material Adverse Effect.

                  (e) All contributions and premiums required by law or by the
terms of any Company Benefit Plan or any agreement relating thereto have been
timely made (without regard to any waivers granted with respect thereto) in all
material respects.

                  (f) The liabilities of each Company Benefit Plan that has been
terminated or otherwise wound up, have been fully discharged in material
compliance with applicable law.

                  (g) There has been no violation of ERISA with respect to the
filing of applicable returns, reports, documents and notices regarding any of
Company Benefit Plans with the Secretary of Labor or the Secretary of the
Treasury or the furnishing of such notices or documents to the participants or
beneficiaries of the Company Benefit Plans which, either individually or in the
aggregate, could result in a Company Material Adverse Effect.

                  (h) There are no pending legal proceedings which have been
asserted or instituted against any of the Company Benefit Plans, the assets of
any such Plans or the Company or any ERISA Affiliate or the plan administrator
or any fiduciary of the Company Benefit Plans with respect to the operation of
such plans (other than routine, uncontested benefits claims).

                  (i) Each of the Company Benefit Plans has been maintained, in
all material respects, in accordance with its terms and all provisions of
applicable laws and regulations. All amendments and actions required to bring
each of the Company Benefit Plans into conformity in all material respects with
all of the applicable provisions of ERISA and other applicable laws and
regulations have been made or taken except to the extent that such amendments or
actions are not required by law to be made or taken until a date after the
Closing Date.

                  (j) Except as set forth on the Company Disclosure Schedule,
the Company and its Subsidiaries have never maintained a welfare benefit plan
providing continuing benefits after the termination of employment (other than as
required by applicable Law and at the former employee's own expense), and the
Company, its Subsidiaries and each of their ERISA Affiliates have complied in
all material respects with the notice and continuation requirements of Section
4980B of the Code and the regulations thereunder. The Company's Financial
Statements and Quarterly Financial Statements reflect reserves adequate to
provide the benefits accrued under such retiree welfare benefit plans.


<PAGE>
                                      -14-

                  (k) Except as set forth in the Company Disclosure Schedule,
neither the execution and delivery of this Agreement nor the consummation of the
Transactions will (i) result in any material payment (including, without
limitation, severance, unemployment compensation or golden parachute) becoming
due to any director or employee of the Company or it Subsidiaries, (ii)
materially increase any benefits otherwise payable under any the Company Benefit
Plan or (iii) result in the acceleration of the time of payment or vesting of
any such benefits to any material extent other than vesting of the Company Stock
Options in accordance with their terms.

                  (l) The Company and its Subsidiaries are in compliance in all
material respects with applicable laws and collective bargaining agreements with
respect to all benefit plans, contracts and arrangements covering non-U.S.
Business Employees ("Non-U.S. Benefit Plans"). The Company and its Subsidiaries
have no unfunded liabilities in violation of local law which violation would,
either individually or in the aggregate result in a Company Material Adverse
Effect. All benefits payable under each of the Non-U.S. Benefit Plans are
provided in accordance with the terms of the governing provisions of the
relevant Non-U.S. Benefit Plan. The Company and the Subsidiaries are not aware
of any failure to comply with any applicable law which would or might result in
the loss of tax approval or qualification of any Non-U.S. Benefit Plans.

         Section 4.10 Labor Relations. There are no labor controversies pending
or threatened with respect to the Company and neither the Company nor any U.S.
Subsidiary is a party to any collective bargaining agreements with any labor
union or other representative of employees. No non-U.S. subsidiary is a party to
any collective bargaining agreement with any labor union or other representative
of employees or any works' council or similar entity under applicable laws
except as customary for employees in such country. To the knowledge of the
Company, there is no pending or threatened union organization activity by or
among any of its or its Subsidiaries' employees.

         Section 4.11 Taxes. The Company and its Subsidiaries have duly filed
all material foreign, federal, state and local income, franchise, excise, real
and personal property and other Tax (as defined below) returns and reports
(including, but not limited to, those filed on a consolidated, combined or
unitary basis) required to have been filed by the Company and its Subsidiaries
prior to the date hereof, or requests for extensions to file such returns and
reports have been timely filed; All of the foregoing returns and reports are
true and correct in all material respects, and the Company and its Subsidiaries
have paid or, prior to the Effective Time will pay, all Taxes, whether or not
shown on such returns or reports, as being due or claimed to be due to any
Governmental Entity and the Company has paid and will pay all installments of
estimated taxes due on or before the Effective Time. The Company and its
Subsidiaries have paid or made adequate provision in accordance with GAAP in the
SEC Reports and the Company Financial Statements for all Taxes payable in
respect of all periods ending on or prior to the date of this Agreement and will
have made or provided for all Taxes payable in respect of all periods ended on
or prior to the Closing Date. As of the date hereof, all deficiencies proposed
as a result of any audits have been paid or settled. The Company and each
Subsidiary has paid, collected or withheld, or caused to be paid, collected or
withheld, all amounts of Taxes required to be paid, collected or withheld, other
than such Taxes for


<PAGE>
                                      -15-

which adequate reserves in the Company SEC Reports or the Company Financial
Statements have been established or which are being contested in good faith or
which would not have a Company Material Adverse Effect. There are no claims or
assessments pending against the Company or any Subsidiary for any alleged
deficiency in any Tax, and the Company has not been notified in writing of any
proposed Tax claims or assessments against the Company or any Subsidiary. Except
as set forth in the Company Disclosure Schedule, there is no contract,
agreement, plan or arrangement covering any Person that, individually or
collectively, could give rise to the payment of any amount that would not be
deductible by the Buyer, the Company, or any of the Subsidiaries of the Company
by reason of Section 280G of the Code.

         Section 4.12 Compliance with Applicable Laws. Except as set forth in
the Company SEC Reports filed prior to the date hereof, as of the date of this
Agreement, and, except as set forth in the Company SEC Reports filed after the
date hereof but prior to the Effective Time, as of the Effective Time, the
businesses of each of the Company and its Subsidiaries have not been, and are
not being, conducted in violation of any federal, state, local or foreign law,
statute, ordinance, rule, regulation, judgment, order, injunction, decree,
arbitration award, agency requirement, license or permit of any Governmental
Entity (collectively, "Company Permits"), except for violations or possible
violations that, individually or in the aggregate, are not reasonably likely to
have a Company Material Adverse Effect or prevent or materially burden or
materially impair the ability of the Company to consummate the transactions
contemplated by this Agreement. Except as set forth in the Company SEC Reports
filed prior to the date hereof, no investigation or review by any Governmental
Entity with respect to the Company or any of its Subsidiaries is pending or, to
the Company's knowledge, threatened, nor has any Governmental Entity indicated
an intention to conduct the same. To the knowledge of the Company, no material
change is required in the Company's or any of its Subsidiaries' processes,
properties or procedures in connection with any such Company Permits, and the
Company has not received any notice or communication of any material
noncompliance with any such Company Permits that has not been cured as of the
date hereof. The Company and its Subsidiaries each has all permits, licenses,
franchises, variances, exemptions, orders and other governmental authorizations,
consents and approvals necessary to conduct its business as presently conducted
except those the absence of which are not, individually or in the aggregate,
reasonably likely to have a Company Material Adverse Effect or prevent or
materially burden or materially impair the ability of the Company to consummate
the Merger and the other transactions contemplated by this Agreement.

         Section 4.13 Voting Requirements. The affirmative vote of the holders
of at least a majority of the total number of votes entitled to be cast by the
holders of the Company Common Stock outstanding as of the record date for the
Company Special Meeting is the only vote of the holders of any class or series
of the Company's capital stock or other securities necessary to approve this
Agreement and the transactions contemplated by this Agreement.

         Section 4.14 Material Contracts. Neither the Company nor any subsidiary
is a party or is subject to any note, bond, mortgage, indenture, contract,
lease, license,


<PAGE>
                                      -16-

agreement, understanding, instrument, bid or proposal, and any amendment or
modification thereto, that is required to be described in or filed as an exhibit
to any Company SEC Report that is not so described in or filed as required by
the Securities Act or the Exchange Act, as the case may be, and each such
contract or agreement and all amendments and modifications thereto, and each
note, bond, mortgage, indenture, contract, lease, license, agreement,
understanding, instrument, bid or proposal, and any amendment or modification

defined below) contained in any current marketed product, product under
development or product as to which the Company or any of its Subsidiaries has
ongoing warranty or service obligations (collectively, the "Products"), (b) any
product or service provided to or supplied by the Company or any of its

consideration to be paid or received other than cash on the one hand and goods
and services customarily provided by the Company or used by the Company in its
business in the ordinary course on the other hand. No Consent of any person is
needed in order that each such Company Material Contract shall continue in full
force and effect in accordance with its terms without penalty, acceleration or
rights of early termination by reason of the consummation of the transactions
contemplated by this Agreement, except for Consents the absence of which would
not, in the aggregate, have a Company Material Adverse Effect, and neither the
Company nor any of its Subsidiaries is in violation or breach of or default
under any such Company Material Contract; nor to the Company's knowledge is any
other party to any such Company Material Contract in violation or breach of or
default under any such Company Material Contract.

         Section 4.15 Title to Property. Except as described in the Company
Disclosure Schedule, each of the Company and its Subsidiaries has good and valid
title to, or, in the case of leased properties and assets, valid leasehold
interests in, all of its material tangible properties and assets, real, personal
and mixed, used or held for use in its business, free and clear of any Liens
except (i) for liens imposed by Law in respect of obligations not yet due which
are owed in respect of Taxes or which otherwise are owed to materialmen,
workmen, carriers, warehousemen or laborers not in excess of $100,000 in the
aggregate, (ii) as reflected in the financial statements contained in the
Company SEC Reports and (iii) for such Liens or other imperfections of title and
encumbrances, if any, which would not reasonably be likely, individually or in
the aggregate, to have a Company Material Adverse Effect. Neither the Company
nor any of its Subsidiaries is in violation or breach of or default under the
leases with respect to any real property leased by the Company or


<PAGE>
                                      -17-

its Subsidiaries, nor to the Company's knowledge is any other party to any such
leases in violation or breach of or default under any such leases, any of which
breaches or defaults, with the giving of notice or the passage of time, or both,
would permit the termination of such lease with respect to the facility of the
Company or its Subsidiaries in Natick, Massachusetts, or with respect to the
Company's other real property leases which would, individually or in the
aggregate, have a Company Material Adverse Effect.

         Section 4.16 Intellectual Property.

                  (a) To the Company's knowledge, the Company and its
Subsidiaries, directly or indirectly, own, or are licensed or otherwise possess
legally enforceable rights to use, all patents, trademarks, trade names, service
marks, copyrights and any applications therefor, technology, know-how, computer
software and applications and tangible or intangible proprietary information or
materials that are material to the business of the Company and its Subsidiaries
(the "Company Intellectual Property Rights").

                  (b) Either the Company or one of its Subsidiaries is the owner
of, or the exclusive or non-exclusive licensee of, with all right, title and
interest in and to (free and clear of any liens or encumbrances), the Company
Intellectual Property Rights, and, in the case of the Company Intellectual
Property Rights owned by the Company or one of its Subsidiaries, has rights (and
is not contractually obligated to pay any compensation to any third party in
respect thereof) to the use thereof or the material covered thereby in
connection with the services or products in respect of which the Company
Intellectual Property Rights are being used. The Company or one of its
Subsidiaries has all necessary rights, and has not transferred any such rights,
with respect to its thin film technology and manufacturing processes. With
respect to the Company Intellectual Property Rights: (i) the manufacture, sale,
licensing, or use of any of the services or products of the Company or any of
its Subsidiaries as now manufactured, sold or licensed or used or proposed for
manufacture, use, sale or licensing by the Company or any of its Subsidiaries
does not infringe on any copyright, patent, trade mark, service mark or trade
secret of a third party except for an infringement which would not result in a
Company Material Adverse Effect, (ii) the use by the Company or any of its
Subsidiaries of any trademarks, service marks, trade names, trade secrets,
copyrights, patents, technology or know-how and applications used in the
business of the Company and any of its Subsidiaries as currently conducted or as
proposed to be conducted does not infringe on any copyright, patent, trade mark,
service mark or trade secret of a third party except for an infringement which
would not result in a Company Material Adverse Effect, or (iii) as of the date
of this Agreement, the Company has not received any information challenging the
ownership by the Company or any of its Subsidiaries or the validity of any of
the Company Intellectual Property Rights. All registered trademarks, service
marks and copyrights held by the Company and its Subsidiaries are valid and
subsisting, except to the extent any failure does not constitute a Company
Material Adverse Effect. To the knowledge of the Company, there is no
unauthorized use, infringement or misappropriation of any of the Company
Intellectual Property Rights by any third party, including any employee or
former employee of the Company or any of its Subsidiaries. No Intellectual
Property Right is subject to any outstanding decree, order, judgment, or
stipulation restricting in


<PAGE>
                                      -18-

any manner the licensing thereof by the Company or any Subsidiary, except to the
extent any such restriction does not constitute a Company Material Adverse
Effect. Neither the Company nor any of the Subsidiaries has entered into any
agreement under which the Company or any of the Subsidiaries is restricted from
selling, licensing or otherwise distributing any of its products to any class of
customers, in any geographic area, during any period of time or in any segment
of the market.

                  (c) The Company and its Subsidiaries have integrated certain
Company Intellectual Property Rights into their equipment and processes which
have provided the technical functionality and efficiencies which have been
disclosed to Buyer. The Company has not experienced any material deterioration
in such functionality and efficiencies, including production rates and yields
shown thereon, or any materially increased costs in operations since
[January/February] 1, 2000 to maintain such functionality. Such modifications
have not violated any rights of the equipment manufacturer which would result in
a Company Material Adverse Effect.

                  (d) To the knowledge of Company, the computer systems,
software, hardware, firmware, middleware and other information technology
(collectively, "Information Technology") of the Company and its Subsidiaries are
Year 2000 Ready (as defined below); and none of the Company or any of its
Subsidiaries has experienced any disruption in their Information Technology or
in the services and products provided to the Company or any of the Subsidiaries
by their vendors and suppliers. "Year 2000 Ready" means that Information
Technology is designed to be used prior to, during and after the calendar year
2000 A.D. and such Information Technology will accurately receive, provide and
process date/time data (including, without limitation, calculating, comparing
and sequencing) from, into and between the twentieth and twenty-first centuries
A.D., and leap year calculations and will not malfunction, cease to function or
provide invalid or incorrect results as a result of date/time data (including,
without limitation, to the extent that other Information Technology used in
combination with such Information Technology properly exchanges date/time data
with it).

         Section 4.17 Interested Party Transactions. Since September 30, 1999,
or as described in the Company SEC Reports, no event has occurred that would be
required to be reported by the Company pursuant to Item 404 of Regulation S-K
promulgated by the SEC.

obligations of any nature whether or not accrued, contingent or otherwise,
except for liabilities or obligations incurred in the ordinary course of
business since December 31, 1999 or which individually or in the aggregate are
not material in nature or amount. As of the date of this Agreement, except as
set forth on the Company Disclosure Schedule, no investigation or review by any

Company Disclosure Schedule, the Company has more than one source of supply for
all of raw materials and other supplies necessary for the manufacturer of its

consummation of the Merger.

                  (b) The execution and delivery of this Agreement by Buyer and

subsidiaries, to comply with applicable Law. None of the information relating to
Buyer and its subsidiaries included in the Prospectus/Proxy Statement will be
false or misleading with respect to any material fact or will omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading. If, at any time prior to the meeting of the stockholders of the
Company referenced herein, any information included by Buyer in the
Prospectus/Proxy Statement is or becomes incorrect or incomplete in any material
respect, Buyer shall correct such inaccuracy or omission. Buyer will furnish
such supplemental information as may be necessary in order to cause the
Prospectus/Proxy Statement, insofar as it relates to Buyer and its subsidiaries,
to comply with applicable Law after the mailing thereof to the stockholders of
the Company.

                  (d) The Company and Buyer agree to cooperate in making any
preliminary filings of the Prospectus/Proxy Statement with the SEC, as promptly
as practicable, pursuant to Rule 14a-6 under the Securities Exchange Act, and
shall cooperate in responding to any comments with respect thereto received from
the SEC.

                  (e) Buyer will file the Registration Statement with the SEC
and appropriate materials with applicable state securities agencies as promptly
as practicable and will use all reasonable efforts to cause the Registration
Statement to become effective under the Securities Act at the earliest
practicable date and all such state filed materials to comply with applicable
state securities Laws. The Company authorizes Buyer to utilize in the
Registration Statement and in all such state filed materials, the information
concerning the Company and its subsidiaries provided to Buyer in writing for
this purpose in connection with, or contained in, the Prospectus/Proxy
Statement. Buyer promptly will advise the Company when the Registration
Statement has become effective and of any supplements or amendments thereto, and
Buyer will furnish the Company with copies of all such documents. Except for the
Prospectus/ Proxy Statement or the preliminary prospectus/proxy statement,
neither Buyer nor the Company shall distribute any written material that might
constitute a "prospectus" relating to the Merger or the Company Proposal within
the meaning of the Securities Act or any applicable state securities Law without
the prior written consent of the other party.

                  (f) The Company shall mail the Prospectus/Proxy Statement to
its stockholders as promptly as practicable after the date the Registration

         Section 7.3 Employee Retention. The Company and Buyer shall consult
with each other promptly after the date of this Agreement on the design and
implementation of retention arrangements and non-competition agreements to
retain key employees of the business. Each of the Company and Buyer will act in
good faith to implement the arrangements agreed upon and to encourage the
retention of such key employees and the Company hereby waives any claim that it
may have with respect to any negotiations which Buyer may have with the key
employees of the Company in connection therewith.

         Section 7.4 Public Announcements. On or before the Closing Date, Buyer
and the Company shall not (nor shall they permit any of their respective
Affiliates to), without prior consultation with the other party and such other
party's review of and consent to any public announcement concerning the
transactions contemplated by this Agreement, issue any press release or make any
public announcement with respect to such transactions during such period, and
Buyer and the Company shall, to the extent practicable, allow the other party
reasonable time to review and comment on such release or announcement in advance
of its issuance and use reasonable efforts in good faith to reflect the
reasonable and good faith comments of such other party, provided, however, no
party shall be prevented from making any disclosure required by law at the time
so required because of any delay on the part of the other party. The parties
intend that the initial announcement of the terms of the transactions
contemplated by this Agreement shall be made by joint press release of Buyer and
the Company.

         Section 7.5 Indemnification of the Company's Directors and Officers and
Insurance. Buyer agrees that all rights to indemnification existing as of the
date of this Agreement in favor of any director, officer, employee or agent of
the Company and its subsidiaries (the "Indemnified Parties") as provided in
their respective Certificate of Incorporation, By-laws or comparable
organizational documents or in indemnification agreements with the Company or
any of its Subsidiaries, or otherwise in effect as of the date hereof, shall to
the extent permitted under Delaware Law survive the Merger and shall continue in
full force and effect for a period of not less than six years from and after the
Effective Time, provided that, in the event any claim or claims are asserted or
made within such six-year period, all rights to indemnification in respect of
any such claim or claims, shall continue until final disposition of any and all
such claims. Without limiting the generality of the foregoing, in the event any
such Indemnified Party is or becomes involved in any capacity in any action,
proceeding or investigation in connection with any matter, including, without
limitation, the transactions contemplated by this Agreement, occurring prior to
or at the Effective Time, Buyer shall cause the Surviving Corporation to pay as
incurred such Indemnified Party's legal and other expenses (including the cost
of any investigation and preparation) incurred in connection therewith. The
Surviving Corporation shall cause to be maintained in effect for a period of six
years, the current policies of directors' and officers' liability insurance and
fiduciary liability insurance maintained by the Company (provided that the
Surviving Corporation may substitute therefor policies of at least the same
coverage and amounts containing terms

<PAGE>
                                      -35-

and conditions which are, in the aggregate, no less advantageous to the insured)
with respect to claims arising from facts or events that occurred on or before
the Effective Time; provided, however, that in no event shall the Surviving
Corporation be required to expend in any one year an amount in excess of 200% of
the annual premiums currently paid by the Company for such insurance; and,
provided, further, that if the annual premiums of such insurance coverage exceed
such amount, the Surviving Corporation shall be obligated to obtain a policy
with the greatest coverage available for a cost not exceeding such amount. In
the event Buyer or the Surviving Corporation or any of their respective
successors or assigns (i) consolidates with or merges into any other person and
shall not be the continuing or surviving corporation or entity in such
consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any person, then, and in each case, proper provision
shall be made so that the successors and assigns of Buyer or the Surviving
Corporation, as the case may be, honor the indemnification obligations set forth
in this Section 7.4.

         Section 7.6 Efforts; Consents.

                  (a) Subject to the terms and conditions of this Agreement,
each of the parties hereto agrees to use its reasonable best efforts to take, or
cause to be taken, all actions and to do, or cause to be done, all things
necessary, proper or advisable to consummate and make effective as promptly as
practicable the transactions contemplated by this Agreement and the Merger and
to cooperate with each other in connection with the foregoing. Without limiting
the generality of the foregoing, each of the Company, Merger Subsidiary and
Buyer shall make or cause to be made all required filings with or applications
to Governmental Entities (including under the Securities Act, the Exchange Act
and the Merger Control Laws and to state and local Governmental Entities with
respect to any transfers of Company Permits), and use its reasonable best
efforts to (i) obtain all necessary consents of all Governmental Entities and
other third parties, necessary for such parties to consummate the Transactions,
(ii) oppose, lift or rescind any injunction or restraining order or other order
adversely affecting the ability of the parties to consummate the Transactions,
and (iii) fulfill all conditions to this Agreement.

                  (b) Prior to the Effective Date, the Company shall use its
reasonable best efforts to assist Buyer in its integration of the acquisition of
the Company, including the prompt and orderly transition of employees, customers
and suppliers of the Company's business and providing assistance to Buyer in
connection with the integration of the Company's lines of business and services
with those of Buyer.

         Section 7.7 Notice of Breaches. The Company shall give prompt notice to
Buyer, and Buyer or Merger Subsidiary shall give prompt notice to the Company,
of (i) any representation or warranty made by it contained in this Agreement
which has become untrue or inaccurate in any material respect, or (ii) the
failure by it to comply with or satisfy in any material respect any covenant,
condition, or agreement to be complied with or satisfied by it under this
Agreement; provided, however, that such notification shall not excuse or
otherwise affect the representations, warranties, covenants or agreements of the
parties or the conditions to the obligations of the parties under this
Agreement.

Expenses. Buyer and Merger Subsidiary agree that the Surviving Corporation will
pay all real property transfer, gains and other similar taxes and all
documentary stamps, filing fees, recording fees and sales and use taxes, if any,
and any penalties or interest with respect thereto, payable in connection with
consummation of the Merger without any offset, deduction, counterclaim or
deferment of the payment of the Merger Consideration. The Company has provided
to Buyer a good faith estimate and description of the expenses of the Company
and its Subsidiaries that the Company expects to incur or has incurred in
connection with the transactions contemplated by the Agreement and shall update
such estimate not fewer than five days prior to the Effective Time and at such
other times as may be reasonably requested by Buyer.

         Section 7.9 Acquisition Proposals.

                  (a) The Company agrees that it shall not nor shall any of its
Subsidiaries or any of the officers and directors of the Company or its
Subsidiaries nor any of its or its Subsidiaries' agents and representatives
(including any investment banker, attorney or accountant retained by it or any
of its Subsidiaries),and it shall use its reasonable best efforts to cause the
non-officer employees of the Company and its Subsidiaries not to, directly or
indirectly, initiate, solicit, encourage or knowingly facilitate (including by
way of furnishing information) any inquiries or the making of any proposal or
offer with respect to a merger, reorganization, share exchange, consolidation,
business combination, recapitalization, liquidation, dissolution or similar
transaction involving, or any purchase or sale of all or any significant portion
of the assets or more than 10% of the Company Common Stock or the assets or
capital stock of any of its subsidiaries (any such proposal or offer (other than
a proposal or offer made by Buyer or an affiliate thereof) being hereinafter
referred to as an "Acquisition Proposal"). The Company further agrees that
neither it nor any of its Subsidiaries nor any of the officers and directors of
it or its Subsidiaries shall, and that it shall direct and use its reasonable
best efforts to cause its and its Subsidiaries' employees, agents and
representatives (including any investment banker, attorney or accountant
retained by it or any of its Subsidiaries) not to, directly or indirectly, have
any discussion with or provide any confidential information or data to any
Person relating to an Acquisition Proposal, or engage in any negotiations
concerning an Acquisition Proposal, or knowingly facilitate any effort or
attempt to make or implement an Acquisition Proposal or accept an Acquisition
Proposal. Notwithstanding the foregoing, the Company or its Board of Directors
shall be permitted to comply with (i) Rule 14e-2 promulgated under the Exchange
Act with regard to an Acquisition Proposal, and (ii) in response to an
unsolicited bona fide written Acquisition Proposal by any Person, to engage in
any discussions or negotiations with, or provide any information to, any Person
in response to an unsolicited bona fide written Acquisition Proposal by any such
Person, if and only to the extent that: (w) the Company Special Meeting shall
not have occurred; (x) the Board of Directors of the Company, upon the advice of
the Company's Financial Advisors, concludes in good faith that such Acquisition
Proposal could reasonably be expected to constitute a Superior Proposal (as
defined in Section 10.8(a) below); (y) prior to providing any information or
data to any Person in connection with an Acquisition Proposal by any such
Person, the Company Board of Directors receives from such Person

<PAGE>
                                      -37-

an executed confidentiality agreement on terms substantially similar to those
contained in the Confidentiality Agreement; and (z) at least two days prior to
providing any information or data to any Person or entering into discussions or
negotiations with any Person, the Board of Directors of the Company notifies
Buyer promptly of such inquiries, proposals or offers received by, any such
information requested from, or any such discussions or negotiations sought to be
initiated or continued with, any of its representatives indicating, in
connection with such notice, the name of such Person and the material terms and
conditions of any proposals or offers. The Company agrees that it will keep
Buyer informed, on a current basis, of the status and terms of any such
proposals or offers and the status of any such discussions or negotiations. The
Company agrees that it will immediately cease and cause to be terminated any
existing activities, discussions or negotiations with any parties conducted
prior to the date of this Agreement with respect to any Acquisition Proposal.
The Company agrees that it will take the necessary steps to promptly inform the
individuals or entities referred to in the first sentence of this Section 7.9(a)
of the obligations undertaken in this Section 7.9(a) and that any breach of the
provisions of this Section 7.9(a) by any officer or director of the Company or
its subsidiaries or any investment banker, financial advisor, attorney,
accountant or other representative of the Company or its subsidiaries will be
deemed a breach by the Company.

                  (b) Except as permitted in this Section 7.9(b), neither the
Board of Directors of the Company nor any committee thereof shall:

                           (i) withdraw or modify, or propose publicly to
                           withdraw or modify, in a manner adverse to Buyer, or
                           take any action not explicitly permitted by this
                           Agreement that would be inconsistent with, the
                           approval or recommendation by such Board of Directors
                           or such committee of the transactions contemplated by
                           this Agreement,

                           (ii) approve or recommend, or propose publicly to
                           approve or recommend, any
                           Acquisition Proposal, or

                           (iii) cause the Company to enter into any letter of
                           intent, agreement in principle, acquisition agreement
                           or other similar agreement (each, an "Acquisition
                           Agreement") related to any Acquisition Proposal.

                  Notwithstanding the foregoing, in the event that prior to the
vote on the transactions at the Company Special Meeting, the Board of Directors
of the Company determines in good faith, that an Acquisition Proposal
constitutes a Superior Proposal, the Board of Directors of the Company may:

                           (x) withdraw or modify its approval or recommendation
                           of the Transactions in connection with the Company
                           Special Meeting,

                           (y) approve or recommend a Superior Proposal and

<PAGE>

                           (z) if it so chooses, cause the Company to enter into
                           an Acquisition Agreement with respect to such
                           Superior Proposal but, in each case, only at a time
                           that is after: (A) the later of Company Special
                           Meeting or the fifth (5th) day following Buyer's
                           receipt of written notice from the Company advising
                           Buyer that the Board of Directors of the Company has
                           received a Superior Proposal, specifying the material
                           terms and conditions of such Superior Proposal,
                           identifying the person making such Superior Proposal,
                           and advising Buyer that the Board of Directors of the
                           Company has determined that it will no longer
                           recommend approval of the Transactions; (B) the
                           Company has paid the Termination Fee (as defined in
                           Section 9.3(b) to Buyer; and (C) the Company has
                           terminated this Agreement in accordance with its
                           terms.

delivery of this Agreement, or as otherwise provided in this Section 7.10, and

this Agreement is entering into a stockholders' agreement pursuant to which such
Persons agree to vote the shares of the Company Common Stock owned by them in
favor of the Company Proposal at the Company Special Meeting and provide the
proxies named therein with such Person's irrevocable proxy with respect to such
vote (the "Related Agreement"). The Company shall, prior to the Effective Time,
negotiate the termination of the consulting agreement, dated August 31, 1999,
between the Company and ANC Management Corp. prior to the Closing Date without
any payment or liability of the Company with respect to such termination, except

Corporation to continue or maintain any stock purchase or other equity plan
related to the equity of the Company or the Surviving Corporation or to change
the eligibility requirements of any stock or other equity plan of Buyer; or (C)

                           limitation" or the phrase "but not limited to" in all
                           places where such words appear in this Agreement.

                           (iii) This Agreement is the joint drafting product of
                           Buyer and the Company and each provision has been
                           subject to negotiation and agreement and shall not be

                           thereof.

                           (iv) Each case in this Agreement where a contract or
                           agreement is represented or warranted to be
                           enforceable will be deemed to include as a limitation
                           to the extent that enforceability may be subject to

                           fraudulent conveyance, moratorium or similar Laws

                           terms shall be deemed to refer to such terms as they

Board of Directors
NetOptix Corporation
Sturbridge Business Park

P.O. Box 550
Sturbridge, Massachusetts  01566


Ladies and Gentlemen:

                  You have requested our opinion as to the fairness, from a
financial point of view, to the holders of shares of the common stock, par value
$0.01 per share (the "Company Common Stock"), of NetOptix Corporation ("the
Company") of the Exchange Ratio (as defined below) in connection with the Merger
(as defined below) contemplated by the Agreement and Plan of Merger (the
"Agreement") to be entered into among the Company, Corning Incorporated
("Parent") and CI Subsidiary Inc., a direct wholly owned subsidiary of Parent
("Merger Sub").

                  As more specifically set forth in the Agreement, and subject
to the terms and conditions thereof, Merger Sub will merge with and into the
Company (the "Merger"), and each issued and outstanding share of Company Common
Stock, other than certain shares to be cancelled pursuant to the Agreement, will
be converted into the right to receive 0.90 (the "Exchange Ratio") of a share of
the common stock, par value $0.50 per share (the "Parent Common Stock"), of
Parent.

                  In arriving at our opinion, we reviewed a draft of the
Agreement, dated February 11, 2000, and held discussions with certain senior
officers, directors and other representatives and advisors of each of the
Company and Parent concerning the businesses, operations and prospects of the
Company and Parent. We examined certain publicly available business and
financial information relating to the Company and Parent as well as certain
financial forecasts and other information and data for the Company and Parent
which were provided to or otherwise discussed with us by the managements of the
Company and Parent, including certain strategic implications and operational
benefits anticipated to result from the Merger. We reviewed the financial terms
of the Merger as set forth in the Agreement in relation to, among other things:
current and historical market prices and trading volumes of Company Common Stock
and Parent Common Stock; the historical and projected earnings and other
operating data of the Company and Parent; and the historical and projected
capitalization and financial condition of the Company and Parent. We considered,
to the extent publicly available, the financial terms of certain other similar
transactions recently effected that we considered relevant in evaluating the
Exchange Ratio and analyzed certain financial, stock market and other publicly
available

<PAGE>
[LOGO]


information relating to the businesses of other companies whose operations we
considered relevant in evaluating those of the Company and Parent. We also
evaluated the pro forma financial impact of the Merger on Parent. In addition to
the foregoing, we conducted such other analyses and examinations and considered
such other information and financial, economic and market criteria as we deemed
appropriate in arriving at our opinion.

                  In rendering our opinion, we have assumed and relied, without
independent verification, upon the accuracy and completeness of all financial
and other information and data publicly available or furnished to or otherwise
reviewed by or discussed with us and have further relied upon the assurances of
the managements of the Company and Parent that they are not aware of any facts
that would make any of such information inaccurate or misleading. With respect
to financial forecasts and other information and data provided to or otherwise
reviewed by or discussed with us, we have been advised by the managements of the
Company and Parent that such forecasts and other information and data were
reasonably prepared on bases reflecting the best currently available estimates
and judgments of the managements of the Company and Parent as to the future
financial performance of the Company and Parent and the strategic implications
and operational benefits anticipated to result from the Merger. We express no
view with respect to such forecasts and other information and data or the
assumptions on which they were based. We have assumed, with your consent, that
the Merger will be treated as a tax-free reorganization for U.S. federal income
tax purposes. We have not made or been provided with an independent evaluation
or appraisal of the assets or liabilities (contingent or otherwise) of the
Company or Parent nor have we made any physical inspection of the properties or
assets of the Company or Parent. You have advised us, and we have assumed, that
the final terms of the Agreement will not vary materially from those set forth
in the draft reviewed by us. We have further assumed that the Merger will be
consummated in a timely fashion in accordance with the terms of the Agreement
without waiver of any of the conditions precedent to the Merger contained in the
Agreement.

                  Our opinion, as set forth herein, relates to the relative
values of the Company and Parent. We are not expressing any opinion as to what
the value of the Parent Common Stock actually will be when issued in the Merger
or the price at which the Parent Common Stock will trade subsequent to the
Merger. We were not requested to consider, and our opinion does not address, the
relative merits of the Merger as compared to any alternative business strategies
that might exist for the Company or the effect of any other transaction in which
the Company might engage. Our opinion necessarily is based upon information
available to us and financial, stock market and other conditions and
circumstances existing and disclosed to us as of the date hereof.

                  Salomon Smith Barney Inc. is acting as financial advisor to
the Company in connection with the Merger and will receive a fee for our
services, a portion of which is payable only upon the consummation of the
Merger. We have in the past provided and currently are providing investment
banking services to the Company and Parent unrelated to the Merger, for which we
have received and will receive compensation. In the ordinary course of our
business, we and our affiliates may actively trade or hold the securities of the
Company and Parent for our own account or for the account of our customers and,
accordingly, may at any time hold a long

                                       2

or short position in such securities. Salomon Smith Barney Inc. and its
affiliates (including Citigroup Inc. and its affiliates) may maintain
relationships with the Company and Parent and their respective affiliates.

                  Our advisory services and the opinion expressed herein are
provided for the information of the Board of Directors of the Company in its
evaluation of the Merger and our opinion is not intended to be and does not
constitute a recommendation of the Merger to the Company or a recommendation to
any stockholder as to how such stockholder should vote on any matters relating
to the Merger.

                  Based upon and subject to the foregoing, our experience as
investment bankers, our work as described above and other factors we deemed
relevant, we are of the opinion that, as of the date hereof, the Exchange Ratio
is fair, from a financial point of view, to the holders of shares of Company
Common Stock.

                                Very truly yours,

                               /s/Salomon Smith Barney Inc.

with Section 1 hereof. Each Stockholder agrees to execute such other instruments
as may reasonably be necessary or advisable to effect the intent of each proxy

Beneficially Owned (and if given shall not be effective).

                  (b) Each Stockholder represents and warrants that any proxies
(other than the proxies contained in Section 2(a) hereof) heretofore given in
respect of such Stockholder's Shares Beneficially Owned are not irrevocable or
if irrevocable, that, upon execution and delivery of this Agreement, the valid
consent to the revocation of such proxies from the party or parties to whom such
proxies were heretofore granted will be obtained, and that any such other
proxies are hereby revoked to the extent necessary to effect the transactions
contemplated by Section 1 hereof. Each Stockholder understands and acknowledges

set forth in this Section 2 is given in connection with the execution of the
Merger Agreement, and that such irrevocable proxy is given to secure the
performance of the duties of such Stockholder in accordance with this Agreement.
Each Stockholder hereby further affirms that his or its irrevocable proxy is
coupled with an interest and may under no circumstances be revoked. This
irrevocable proxy is executed and intended to be irrevocable in accordance with
the applicable provisions of the Delaware General Corporation Law. This
irrevocable proxy shall be valid until termination of this Agreement pursuant to
Section 7 hereof.

                  3. Restrictions on Transfer.

                  (a) Each Stockholder covenants and agrees with Buyer that,
prior to the time the NetOptix Stockholders Meeting shall have been completed,
neither such Stockholder nor any of his or its Affiliates, shall, directly or
indirectly, (i) give, offer, sell, transfer, assign, pledge, hypothecate or
otherwise dispose of the record or beneficial ownership of (any such act, a
"Transfer"), or consent to any Transfer of, any or all of the Shares
Beneficially Owned or any interest therein; (ii) enter into any contract,
option, commitment or other arrangement (including any profit sharing

Shares Beneficially Owned by any Stockholder, including all certificates issued
upon transfer or in exchange thereof or in substitution therefor, shall, in
addition to any legend(s) required by law, bear the following legend:

                     THE SECURITIES REPRESENTED BY THIS
                CERTIFICATE ARE SUBJECT TO CERTAIN VOTING
                LIMITATIONS AND MAY NOT BE TRANSFERRED, SOLD,
                ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE
                DISPOSED OF EXCEPT IN ACCORDANCE WITH THE
                PROVISIONS OF A STOCKHOLDERS AGREEMENT, DATED
                AS OF FEBRUARY 13, 2000. ANY TRANSFEREE OF THESE
                SECURITIES TAKES SUBJECT TO THE TERMS OF SUCH
                AGREEMENT, A COPY OF WHICH IS ON FILE WITH THE
                COMPANY."

                  (d) The certificates representing the Shares Beneficially
Owned by each Stockholder (including any certificate issued upon transfer or in
exchange thereof or in substitution therefor) shall also bear any legend
required under any applicable state securities or blue sky laws.

                  (e) Within three business days of the date of this Agreement,
NetOptix shall make a notation on its records or give instructions to any
transfer agents or registrars for the Shares Beneficially Owned by the
Stockholders in order to implement the restrictions on transfer set forth in

                  (f) As soon as practicable after the execution and delivery of
this Agreement, the Stockholders shall submit any and all certificates
representing the Shares Beneficially Owned by any Stockholder or any of their
respective affiliates to NetOptix so that the legend or legends required by this
Section 3 may be placed thereon and shall cause each permitted transferee to do
the same with respect to the Shares Beneficially Owned by such permitted
transferee.

                  4. Representations and Warranties of the Stockholders. Each
Stockholder, including SAM on behalf of Capital and the Trust, with respect to
himself or itself and the Shares Beneficially Owned by him or it respectively,
hereby represents and warrants, severally and not jointly, to Buyer and Merger
Subsidiary as of the date hereof as follows:

                  (a) Authority. Each Stockholder has all requisite power and
authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
by such Stockholder, and the

<PAGE>
                                      -5-

consummation of the transactions contemplated hereby, have been duly authorized
and approved by all necessary action on the part of such Stockholder and the
entities, if any, on whose behalf such Stockholder acts in his non-individual
capacity (the "Entities"). This Agreement has been duly executed and delivered
by the Stockholders and constitutes a valid and binding obligation of such
Stockholder and the Entities enforceable against them in accordance with its
terms, subject to the effect of any applicable bankruptcy, reorganization,
insolvency, moratorium, or similar law affecting creditors' rights generally and
subject, as to enforceability, to the effect of general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law).

                  (b) No Conflicts. Except for (i) compliance with and filings
under the pre-merger notifications and (ii) the applicable requirements of the
Exchange Act, the execution and delivery of this Agreement do not, and the
consummation by each Stockholder of the Transactions and compliance with the
terms hereof will not, (A) conflict with, or result in any violation of, or
default (with or without notice or lapse of time or both) under, or give rise to
a right of termination, amendment, cancellation or acceleration of any
obligation or to loss of a material benefit under, or to increased, additional,
accelerated or guaranteed rights or entitlements of any person under, or result
in the creation of any lien upon any of the properties or assets of such
Stockholder under any provision of, any trust agreement, loan or credit
agreement, note, bond, mortgage, indenture, lease or other agreement, or
instrument, applicable to such Stockholder or to the property or assets of such
Stockholder, or (B) violate any order, writ, injunction, decree, statute, rule
or regulation applicable to Stockholders or any of the properties or assets of
any Stockholder, including the Shares Beneficially Owned, except for such
conflicts, violations, breaches, defaults or other occurrences which,
individually or the aggregate, have not had and would not reasonably be expected
to prevent or materially delay the ability of the Stockholders to perform their
respective obligations under this Agreement (a "Stockholder Material Adverse
Effect").

                  (c) No Consents. The execution, delivery and performance of
this Agreement by such Stockholder does not, and neither the performance of this
Agreement by such Stockholder nor the consummation of the Transactions by such
person will, require any consent, approval, authorization, order or permit of,
or filing with or notification to any Governmental Entity, except for (i)
applicable requirements of the Exchange Act and the Securities Act, (ii)
compliance with and filings under the legally required pre-merger notifications,
and (iii) the applicable requirements of state securities laws, takeover laws or
Blue Sky laws. If any such Stockholder is married and the Shares Beneficially
Owned by such Stockholder constitute community property or otherwise need
spousal or other approval to be valid and binding, this Agreement has been duly
authorized, executed and delivered by, and, constitutes a valid and binding
agreement of, such Stockholder's spouse enforceable against such spouse in
accordance with its terms, subject to the effect of any applicable bankruptcy,
reorganization, insolvency, moratorium, or similar law affecting creditors'
rights generally and subject, as to enforceability, to the effect of general
principles of equity. No trust of which such Stockholder is a trustee (including

Except as otherwise set forth on the signature pages attached hereto, such
person does not own, of record or beneficially, any shares of capital stock or
other voting securities of NetOptix. Such person has the sole right to dispose
of and vote such Shares, and none of the Shares are subject to any Voting
Arrangement or other voting trust or other agreement, arrangement or restriction
with respect to the voting of such Shares, except as set forth in this
Agreement.

                  (e) No Brokers. Except for Salomon Smith Barney Inc., whose

other person is entitled to any broker's, finder's, financial advisor's or other
similar fee or commission in connection with this Agreement based upon
arrangements made by or on behalf of NetOptix, such Stockholder or the Entities.

                  5. Acquisition Proposals. Each Stockholder agrees that neither
such Stockholder nor any of its Affiliates or any of the managers or members of
Capital nor any of its employees, agents and representatives (including any
investment banker, attorney or accountant retained by such person or any of its
Affiliates), shall, directly or indirectly, initiate, solicit, encourage or
knowingly facilitate (including by way of furnishing information) any inquiries
or the making of any proposal or offer with respect to a merger, reorganization,
share exchange, consolidation, business combination, recapitalization,
liquidation, dissolution or similar transaction involving, or any purchase or
sale of all or any significant portion of the assets or more than 10% of the
Common Stock of NetOptix or the assets or capital stock of any of its
subsidiaries (any such proposal or offer (other than a proposal or offer made by
Buyer or an affiliate thereof) being hereinafter referred to as an "Acquisition
Proposal"). Except as may be permitted under Section 8 hereof each Stockholder
further agrees that neither such Stockholder nor any of his or its Affiliates
nor any of the managers or members of Capital or its Affiliates shall, and that
each of the Stockholders shall direct and use his or its reasonable best efforts
to cause their respective' employees, agents and representatives (including any
investment banker, attorney or accountant retained by any of such persons or any
of its Affiliates) not to, directly or indirectly, have any discussion with or
provide any confidential information or data to any Stockholder relating to an
Acquisition Proposal, or engage in any negotiations concerning an Acquisition
Proposal, or knowingly facilitate any effort or attempt to make or implement an
Acquisition Proposal or accept an Acquisition Proposal. Each Stockholder agrees
that such Stockholder will immediately cease and cause to be terminated any
existing activities, discussions or negotiations with any parties conducted
heretofore with respect to any Acquisition Proposal. Capital agrees that it will

referred to in the first sentence of this Section 5 of the obligations
undertaken in this Section 5 and that any breach of the provisions of this
Section 5 by any officer or director of Capital or its Affiliates or any
investment banker, financial advisor, attorney, accountant or other
representatives will be deemed a breach by Capital.

                  6. Assignment. Neither this Agreement nor any of the rights,
interests or obligations hereunder shall be assigned by any of the parties
hereto without the prior written consent of the other parties (other than the
rights of substitution and resubstitution with respect to the proxies granted
herein) and any purported assignment in violation of this Section 6 shall be
void and of no effect. Subject to the preceding sentence, this Agreement will be
binding upon, inure to the benefit of and be enforceable by the parties and
their respective administrators, heirs, legal representatives, successors and
permitted assignees.

                  7. Termination. This Agreement shall terminate immediately
upon the earlier of: (i) the termination of the Merger Agreement by mutual
agreement of NetOptix and Buyer or, in accordance with the terms of the Merger
Agreement, by NetOptix as a result of breaches or non-performance by Buyer, (ii)

                  8. Stockholder Capacity. By executing and delivering this
Agreement, each of the Stockholders makes no agreement or understanding herein
as to his capacity as a director or officer of NetOptix of any subsidiary of
NetOptix. Each of the Stockholders signs solely in his or its capacity as the
beneficial owner of NetOptix's Shares and nothing herein shall limit or affect
any actions taken by each Stockholder, or his or its Affiliates, in his or its
capacity as an officer or director of NetOptix or any subsidiary of NetOptix to
the extent specifically permitted by the Merger Agreement including without
limitation Section 7.9 thereof.

                  9. Binding Obligations. Upon execution hereof by Buyer, and
any Stockholder, this Agreement shall be binding upon and inure to the benefit
of Buyer, Merger Subsidiary, and each such Stockholder, regardless of the
failure of any other party listed on the signature page hereto to execute this
Agreement.

                  10. General Provisions.

                  (e) Interpretation.

         When a reference is made in this Agreement to Sections, such reference
shall be to a Section to this Agreement unless otherwise indicated. The headings
contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement. Wherever the words
"include", "includes" or "including" are used in this Agreement, they shall be
deemed to be followed by the words "without limitation."

         The parties acknowledge and agree that: (A) each party to this
Agreement and his or its counsel reviewed and negotiated the terms and
provisions of this Agreement and

<PAGE>
                                      -10-

have contributed to its revision; (B) the rule of construction to the effect
that any ambiguities are resolved against the drafting party shall not be
employed in the interpretation of this Agreement; and (C) the terms and
provisions of this Agreement shall be construed fairly as to both parties
hereto, regardless of which party was generally responsible for the preparation
of this Agreement or any provision hereof.

                  (f) Counterparts. This Agreement may be executed in two or
more counterparts, all of which shall be considered one and the same agreement,
and shall become effective when two or more of the counterparts have been signed

that each party need not sign the same counterpart.

                  (g) Entire Agreement; No Third-Party Beneficiaries. This
Agreement (including the documents and instruments referred to herein)
constitutes the entire agreement and supersedes all prior agreements and
understandings, both written and oral, among the parties with respect to the

other than the parties hereto any rights or remedies hereunder.

                  (h) Governing Law. This Agreement shall be construed in

principles of conflicts of laws thereof.

                  (i) Consent to Jurisdiction; Consent to Service. IN THE EVENT
OF ANY LITIGATION, CLAIM OR OTHER LEGAL PROCEEDING WITH RESPECT TO ANY MATTER
PERTAINING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, THE
PARTIES HERETO HEREBY WAIVE THE RIGHT TO A TRIAL BY JURY. THE PARTIES HERETO
HEREBY READILY CONSENT TO THE NON-EXCLUSIVE JURISDICTION AND VENUE OF THE COURTS

                  (j) Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect. Upon such determination that any

parties hereto shall negotiate in good faith to modify this Agreement so as to

extent permitted by applicable law in an acceptable manner to the end that the


<PAGE>
                                      -11-

transactions contemplated hereby are fulfilled to the extent possible. If no
such agreement is reached between the parties, the term or provision which is
determined to be invalid, illegal or incapable of being enforced shall

legally permissible.

ITEM 20. INDEMNIFICATION OF OFFICERS AND DIRECTORS

     Sections 722 and 723 of the Business Corporation Law of the State of New
York provide that a corporation may indemnify its current and former directors
and officers under certain circumstances. Article VIII of the Company's Bylaws
provides that the Company 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 Company to the full extent
permitted by, and consistent with, the Business Corporation Law.

     Section 402(b) of the Business Corporation Law provides that a corporation
may include a provision in its certificate of incorporation limiting the
liability of its directors to the corporation or its shareholders for damages
for the breach of any duty, except for a breach involving intentional
misconduct, bad faith, a knowing violation of law or receipt of an improper
personal benefit or for certain illegal dividends, loans or stock repurchases.
Paragraph 7 of the Company's Restated Certificate of Incorporation contains such
a provision.

ITEM 22. UNDERTAKINGS

     (a) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the 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.

     (b) (1) The undersigned Registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

     (b) (2) The Registrant undertakes that every prospectus (i) that is filed
pursuant to the paragraph immediately preceding, or (ii) that purports to meet
the requirements of section 10(a)(3) of the Securities Act and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to the Registration Statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act, 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.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant 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 Registrant 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 the Securities Act and will be governed by the final
adjudication of such issue.

     (d) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Proxy
Statement/Prospectus pursuant to Item 4, 10(b), 11, or 13 of this Form S-4,
within one business day of receipt of such request, and to send the incorporated
documents by first class mail or other equally prompt means. This includes
information contained in documents filed subsequent to the effective date of the
Registration Statement through the date of responding to the request.

     (e) The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.

                                   Exhibit 5.1

   Opinion of William D. Eggers, Senior Vice President and General Counsel of
                 Corning Incorporated, as to the Legality of the
                           Securities Being Registered

March 16, 2000

Corning Incorporated
One Riverfront Plaza
Corning, New York 14831

Ladies and Gentlemen:

         I refer to the registration statement on Form S-4 (the "Registration
Statement") being filed by Corning Incorporated, a New York corporation
("Corning"), with the Securities and Exchange Commission under the Securities
Act of 1933, as amended (the "Securities Act"), relating to the registration of
up to 12,080,607 shares of common stock, par value $0.50 per share, of Corning
(the "Shares"). The Shares are to be issued pursuant to the terms of the
Agreement and Plan of Merger, (the "Merger Agreement") dated as of February 13,
2000, among Corning, CI Subsidiary, Inc., a Delaware corporation and
wholly-owned subsidiary of Corning ("CI Subsidiary") and NetOptix Corporation, a
Delaware corporation ("NetOptix"). The Merger Agreement provides for the merger
of CI Subsidiary with and into NetOptix, with NetOptix surviving the merger as a
wholly-owned subsidiary of Corning.

         I am familiar with the terms of the Merger Agreement, and the proposed
issuance of the Shares thereunder, and have examined such records, documents and
questions of law, and satisfied myself as to such matters of fact, as I have
considered relevant and necessary as a basis for this opinion.

         Based on the foregoing, I am of the opinion that:

         1. Corning is duly incorporated and validly existing under the laws of
the State of New York; and

         2. The Shares will be legally issued, fully paid and nonassessable when
(i) the Registration Statement, as finally amended, shall have become effective
under the Securities Act; and (ii) certificates representing the Shares have
been duly executed, countersigned and registered and duly delivered in
accordance with the terms of the Merger Agreement.

         I hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement and to the reference to me under the heading "LEGAL
MATTERS" contained in the Proxy Statement/ Prospectus forming a part of the
Registration Statement.

                                                     Very truly yours,

                                                     /s/ William D. Eggers

                          Opinion of Nixon Peabody LLP

March 16, 2000

Corning Incorporated
One Riverfront Plaza
Corning, NY 14831

Ladies and Gentlemen:


         We are acting as counsel to Corning Incorporated ("Corning"), a New
York corporation in connection with the proposed merger (the "Merger") of CI
Subsidiary, Inc. ("Merger Sub"), a Delaware corporation and direct wholly-owned
subsidiary of Corning, with and into NetOptix Corporation ("NetOptix"), a
Delaware corporation, pursuant to an Agreement and Plan of Merger (the
"Agreement"), dated as of February 13, 2000, by and among Corning, Merger Sub,
and NetOptix. Corning is filing with the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended, a registration
statement on Form S-4 (the "Registration Statement") with respect to the common
stock of Corning (the "Corning Common Stock") to be issued to holders of shares
of common stock of NetOptix (the "NetOptix Common Stock") in connection with the
Merger. At your request in connection with the filing of the Registration
Statement, we are rendering our opinion concerning certain federal income tax
consequences of the Merger.

         For purposes of the opinion set forth below, we have, with the consent
of Corning and the consent of NetOptix, relied upon the accuracy and
completeness of the statements and representations (which statements and
representations we have neither investigated nor verified) and relied upon
convenants contained in the certificates of Corning, Merger Sub and NetOptix
(copies of which are attached hereto and which are incorporated herein by
reference). We have assumed that the statements and representation in those
certificates will be complete and accurate as of the Effective Time and the
covenants set forth in these certificates will be complied with in all material
respects. We have also relied upon the accuracy of the factual information set
forth in the Registration Statement and the Proxy Statement-Prospectus
(together, the "Proxy Statement") filed with the Commission, as amended through
the date hereof, in connection with the Merger. Any capitalized term used and
not defined herein has the meaning given to it in the Agreement.

         We have also assumed that the transactions contemplated by the
Agreement will be consummated in accordance with the terms of the Agreement in
all material respects and as described in the Proxy Statement and that the
Merger will qualify as a statutory merger under applicable state laws. We are of
the opinion that, subject to the limitations set forth therein, the discussion
contained in the Proxy Statement under the caption "The Merger--Material Federal
Income Tax Consequences" is an accurate summary of the material federal income
tax consequences of the Merger to holder of NetOptix Common Stock under
currently applicable law.

                                    -II-11-
<PAGE>

         We hereby consent to the filing of this opinion with the Commission as
an exhibit to the Registration Statement and to the reference to us under the
caption "The Merger--Material Income Tax Consequences" and elsewhere in the
Proxy Statement. In giving such consent, we do not hereby admit that we are in
the category of persons whose consent is required under Section 7 of the
Securities Act of 1933, as amended, and the rules and regulations of the
Commission promulgated thereunder.

                                                     Very truly yours,

                        Opinion of Edwards & Angell, LLP

                                                              March 16, 2000


NetOptix Corporation
Sturbridge Business Park
Sturbridge, MA 01566

Ladies and Gentlemen:

                  We have acted as counsel to NetOptix Corporation, a Delaware
corporation ("NetOptix"), in connection with the proposed merger (the "Merger"),
in which CI Subsidiary, a Delaware corporation ("Sub"), a wholly-owned
subsidiary of Corning Incorporated, a New York corporation ("Corning"), will be
merged into NetOptix pursuant to the Agreement and Plan of Merger ("Agreement")
dated as of February 13, 2000, among NetOptix, Corning and Sub.

                  At your request, in connection with the filing of the
Registration Statement on Form S-4 filed with the Securities and Exchange
Commission in connection with the Merger (the "Registration Statement"), we are
rendering our opinion pursuant to Item 601(b)(8) of Regulation S-K.

                  For purposes of the opinion set forth below, we have relied,
with the consent of NetOptix and the consent of Corning, upon the accuracy and
completeness of the statements and representations (which statements and
representations we have neither investigated nor verified) contained,
respectively, in the certificates of the officers of NetOptix and Corning dated
the date hereof, and have assumed that such statements and representations will
be complete and accurate as of the Effective Time. With respect to the
certificates described in the immediately preceding sentence, we have relied
only on factual statements and representations contained therein and, to the
extent that such certificates also contain legal conclusions, we have not relied
upon such conclusions. We have also relied upon the accuracy of the Registration
Statement and the Proxy Statement-Prospectus of NetOptix and Corning (the "Proxy
Statement-Prospectus") included therein. Any capitalized term used and not
defined herein has the meaning given to it in the Proxy Statement-Prospectus or
the appendices thereto (including the Merger Agreement).

                  We have also assumed that the transactions contemplated by the
Merger Agreement will be consummated in accordance therewith and as described in
the Proxy Statement-Prospectus.

                  Based upon and subject to the foregoing, it is our opinion
that, under currently applicable United States federal income tax law, the
Merger will be treated as a "reorganization" within the meaning of Section
368(a) of the Internal Revenue Code of 1986, as amended and, accordingly:

        1.    No gain or loss will be recognized by the holders of NetOptix
              common stock who exchange their NetOptix common stock for Corning
              common stock pursuant to the merger, except with respect to any
              cash received in lieu of a fractional share of Corning common
              stock;

        2.    The aggregate tax basis of the Corning common stock received in
              the merger by each holder of NetOptix common stock will be the
              same as the aggregate tax basis of the NetOptix common stock
              surrendered in exchange therefor, reduced by any


                                    -II-13-
<PAGE>

              amount of tax basis allocable to a fractional share interest in
              Corning common stock for which cash is received;

        3.    The holding period of a holder of NetOptix common stock for
              Corning common stock received in the merger will include the
              holding period for the NetOptix common stock surrendered in
              exchange therefor;

        4.    A NetOptix stockholder who receives cash in lieu of a fractional
              share interest in Corning common stock pursuant to the merger will
              be treated as having received such cash in exchange for such
              fractional share interest and generally will recognize capital
              gain or loss on such deemed exchange in an amount equal to the
              difference between the amount of cash received and the tax basis
              of the NetOptix common stock allocable to such fractional share
              interest; and

        5.    No gain or loss will be recognized by Corning, Corning
              shareholders, Sub, or NetOptix as a result of the merger.

                                                     Very truly yours,
