Dear Stockholder of NetOptix Corporation:

    The Board of Directors of NetOptix Corporation has unanimously approved a
merger in which Corning Incorporated will acquire NetOptix. In 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, and NetOptix will become a wholly-owned
subsidiary of Corning. Corning common stock is listed on the New York Stock
Exchange under the symbol "GLW". As of April 10, 2000, Corning's closing stock
price was $189.19.

    The merger cannot be completed unless the holders of a majority of the
outstanding shares of NetOptix's common stock approve the merger and adopt the
merger agreement. NetOptix has scheduled a special meeting of its stockholders
for May 12, 2000 to vote on this matter. If you were a stockholder of record on
April 10, 2000, you may vote at this meeting. Your vote is very important.

                     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 May 12, 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 April 10, 2000 the closing price per share of Corning common stock on the
    NYSE was $189.19 and of NetOptix common stock on the NASDAQ was $167.38.

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.

<PAGE>
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 36 and 37 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

    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 23 AND 24)

    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;

    - 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;

                                       4
<PAGE>
    - 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.

    To review the reasons for the merger in greater detail, see pages 23 and 24.

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.

INTERESTS OF DIRECTORS AND OFFICERS IN THE MERGER (PAGES 32 THROUGH 34)

    In determining how to vote at the special meeting, you should be aware that
certain officers and directors of NetOptix may have interests in the merger that
are different from your interests as holders of common stock. These include the
following:

    - 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

                                       5

      prior to the effective time of the merger. As of April 10, 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 Gerhard R.
      Andlinger, the Chairman of the Board and Chief Executive Officer of
      NetOptix as well as its principal stockholder, 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.

    - NetOptix may, prior to the closing, amend options to purchase an 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 estate or tax planning purposes.

    - Andlinger Capital XIII LLC, Mr. Andlinger, Stephen A. 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

      Stockholder Voting Agreement and Irrevocable Proxy, dated as of
      February 13, 2000. A total of 4,978,117 shares (5,003,117 shares if 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 39.88% of the total number of shares of NetOptix common stock
      outstanding as of April 10, 2000. 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 held a warrant issued January 26, 1999, to
      purchase 1,000,000 shares of NetOptix common stock for a price of $1.50
      per share which has been exercised.

    - On February 13, 2000, Corning entered into a letter agreement with Ralf T.
      Faber, the President of NetOptix, to clarify the terms of his continued
      employment after the closing date of the merger. Under the letter
      agreement, Mr. Faber has agreed to serve as the President and CEO of
      Corning NetOptix, Inc. the proposed new name of NetOptix, for a term of
      three years.

    - Corning will indemnify and maintain directors and officers liability
      insurance for NetOptix's directors and officers for six years after the
      effective time of the merger.

    - The NetOptix board of directors intends to adopt a resolution exempting
      the disposition to Corning of NetOptix securities by NetOptix directors
      and executive officers from liability under the federal securities laws
      for short-swing trading.

OPINION OF SALOMON SMITH BARNEY INC. (PAGES 25 THROUGH 32)

    Salomon Smith Barney Inc., as financial advisor to NetOptix, delivered its
written opinion, dated February 13, 2000, to the NetOptix board of directors
that, as of such date, the exchange ratio was fair to the stockholders of
NetOptix common stock from a financial point of view. The full text of the
opinion of Salomon Smith Barney Inc., dated February 13, 2000, is attached as
Annex B and should be read carefully in its entirety to understand the
procedures followed, assumptions made, matters considered and limitations on the
review undertaken by Salomon Smith Barney Inc. in providing its opinion. The
Salomon Smith Barney Inc. opinion is directed to the NetOptix board of directors
and does not constitute a recommendation to any NetOptix stockholder as to how
such stockholder should vote on the proposed merger.

THE MERGER AGREEMENT

CONVERSION OF SECURITIES (PAGE 39)

    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 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 40)

    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

                                       7
<PAGE>
    - 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 (PAGES 42 AND 43)

    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.

    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 44 AND 45)

    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;

                                       8
<PAGE>
    - 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

    - 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 45)

    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 (PAGE 38)

    On April 2, 2000, the required waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act relating to the merger terminated. 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 38)

    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 36 AND 37)

    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.

                                       9
<PAGE>
ACCOUNTING TREATMENT (PAGE 37)

    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.

RISK FACTORS RELATING TO THE MERGER (PAGE 18)

    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.

EXCHANGE OF CERTIFICATES (PAGE 39)

    After the merger, Corning or its agent will mail a letter to you with
instructions for exchanging your stock certificates for certificates
representing shares of Corning common stock and a cash payment in lieu of
fractional shares, if any. YOU SHOULD NOT SEND ANY STOCK CERTIFICATES AT THIS
TIME. The letter of transmittal which you receive will contain instructions as
to when and where to send your NetOptix stock certificates.

RECENT DEVELOPMENTS (PAGE 51)

    Corning announced on March 16, 2000, that based on its strong results
through February, Corning expects to report first-quarter earnings before
special items in the range of $0.53 to $0.55 per share, approximately 50% ahead
of 1999 first-quarter earnings of $0.36. Corning also announced that it expects
to report full-year 2000 earnings before special items and before consideration
of the acquisition of NetOptix of approximately $2.45.

    Special charges related to the acquisition of Oak Industries and British
Telecommunications' Photonics Technology Research Center will be included in
Corning's first-quarter results. These items will reduce reported first-quarter
and full year results by approximately $70 million after tax, or $0.25 per
share.

    The NetOptix acquisition will be accounted for as a purchase and will not
impact Corning's results until the transaction is completed in the second
quarter. Excluding the amortization of goodwill and other acquired intangible
assets, the effect of the NetOptix acquisition is expected to be mildly dilutive
to Corning's earnings per share in 2000 and accretive in 2001 and thereafter.
Corning is currently studying the impact of purchase accounting for the NetOptix
acquisition and expects the useful life of goodwill and other acquired
intangibles to range from seven to ten years. Any acquired in-process research
and development will be expensed in the period the transaction is completed. On
an annual basis amortization of goodwill and purchased intangibles could reduce
Corning's earnings by up to $200 to $300 million after tax.

(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.

                                       11

(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 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. 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" 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

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

                      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.

                              THE SPECIAL MEETING

DATE, TIME AND PLACE

    We are sending this proxy statement/prospectus to you as part of the
solicitation of proxies by the NetOptix board of directors for use at the
special meeting to be held on Friday, May 12, 2000 at 10:00 a.m. Eastern
Standard Time at the offices of Edwards & Angell, LLP, 101 Federal Street,
Boston Massachusetts. We are first mailing this proxy statement/prospectus, the
attached notice of special meeting of stockholders and the enclosed proxy card
to you on or about April 14, 2000.

PURPOSES OF THE SPECIAL MEETING

    At the special meeting, NetOptix stockholders will consider and vote upon a
proposal to approve the merger and adopt the Agreement and Plan of Merger dated
as of February 13, 2000 among Corning, CI Subsidiary, Inc. and NetOptix. The
merger agreement provides, among other things, that CI Subsidiary will be merged
with and into NetOptix, and each outstanding share of NetOptix common stock will
be converted into the right to receive 0.90 of a share of Corning common stock.
CI Subsidiary, Inc. is a wholly-owned subsidiary of Corning.

    NetOptix is not proposing that any matters other than the approval and
adoption of the merger agreement will come before the NetOptix special meeting.
If any matter incident to the conduct of the special meeting should be brought
before the meeting, the persons named in the proxy card will vote in their
discretion with respect to those matters.

    THE BOARD OF DIRECTORS OF NETOPTIX HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" THE APPROVAL OF THE
MERGER AGREEMENT.

RECORD DATE

    The NetOptix board of directors has fixed the close of business on
April 10, 2000 as the record date for the special meeting. Only holders of
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,
12,483,346 shares of NetOptix common stock were outstanding and entitled to vote
held by approximately 297 holders of record.

    The presence, in person or by proxy, of a majority of the shares of NetOptix
common stock is necessary to constitute a quorum at the special 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 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 5,011,617 shares of NetOptix common stock or
approximately 40.15% of the outstanding common

                                       20
<PAGE>
stock. In addition, a total of 4,978,117 shares of NetOptix common stock
(5,003,117 shares if 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 be
tabulated at the special meeting by inspectors of election appointed by
NetOptix.

    You may revoke or change your proxy at any time prior to its being voted by
filing a written instrument of revocation or change with the Secretary of
NetOptix (NetOptix, Sturbridge Business Park, Sturbridge, Massachusetts 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

    NetOptix will pay for the expense of printing and mailing this document and
the material used in this solicitation of proxies. Proxies will be solicited
through the mail and directly by officers, directors and regular employees of
NetOptix not specifically employed for such purpose, without additional
compensation. NetOptix will reimburse banks, brokerage houses and other
custodians, nominees and fiduciaries for their reasonable expenses in forwarding
these proxy materials to the principals. NetOptix will not engage a proxy
solicitor to represent it in connection with the solicitations of proxies.

    Under Delaware law, you will not have appraisal or dissenters' rights in
connection with the merger because NetOptix's common stock was designated as a
national market security on the NASDAQ on the record date for the special
meeting.

    THE MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING ARE OF GREAT IMPORTANCE
TO YOU. WE URGE YOU TO READ AND CAREFULLY CONSIDER THE INFORMATION PRESENTED IN
THIS DOCUMENT, AND TO COMPLETE, DATE, SIGN AND PROMPTLY RETURN THE ENCLOSED
PROXY CARD IN THE ENCLOSED POSTAGE PRE-PAID ENVELOPE.

                                   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 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 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

                                       22
<PAGE>
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 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 36.

    - 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.

                                       23
<PAGE>
    - 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.

    - 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 18. 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 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

                                       25
<PAGE>
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 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:

<TABLE>
<S>                                                           <C>

Last 9 Months...............................................  0.31
Last 6 Months...............................................  0.40
Last 3 Months...............................................  0.52
</TABLE>

    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 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

    - non-convertible preferred stock; plus

    - minority interests; plus

    - out-of-the-money convertible securities; minus

    - investments in unconsolidated affiliates and cash.

</TABLE>

    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.

<PAGE>
    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;

    - 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.

         twelve-month period........................  19.8x-529.0x    152.6x         48.7x         63.3x
</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% 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

    RELATIVE CONTRIBUTION ANALYSIS.

    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.

    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

                                       31
<PAGE>
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 merger
agreement and the merger. See "Reasons for the Merger; Recommendation of the
NetOptix Board of Directors" on pages 23 and 24.

    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,

                                       32
<PAGE>
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.

    - NetOptix may, prior to the closing, amend options to purchase an 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 4,978,117 shares (5,003,117 shares if 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 39.88% 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.

    - On February 13, 2000 Andlinger Capital XIII LLC held a warrant issued
      January 26, 1999, to purchase 1,000,000 shares of NetOptix common stock
      for a price of $1.50 per share which has been exercised.

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

                                       33
<PAGE>
      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 years after the
      effective time of the merger.

                       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.

                                       34
<PAGE>
    EMPLOYEE OPTIONS.

    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.

                                       35
<PAGE>
             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 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

                                       36
<PAGE>
      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;

    - 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

    - 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 2, 2000, the waiting period terminated.

    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. 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
exercised prior to the effective date of the merger and will be assumed by
Corning following the effective time. Each option assumed by Corning will be
exercisable upon the same terms and conditions as under the NetOptix plans,
except as may be modified prior to closing as described above under the heading
"Interests of Directors and Officers in the Merger" and except that each option
will represent the right to acquire the number of Corning shares obtained by
multiplying 0.90 by the number of underlying NetOptix common shares subject to
the NetOptix options. In addition, the option exercise price per share of
Corning common stock will be equal to the option exercise price per share of
NetOptix common stock immediately prior to the merger divided by 0.90.

    Corning will issue to each NetOptix option holder a document evidencing its
assumption of the options. Corning has agreed to file with the SEC a Form S-8 or
other appropriate registration statement covering the shares of Corning common
stock underlying the assumed options no later than five business days after the
effective time of the merger and to keep the registration statement current.

ANDLINGER CAPITAL WARRANT

    The warrant to purchase 1,000,000 shares of NetOptix's common stock for
$1.50 per share held by Andlinger Capital XIII LLC, an affiliate of
Mr. Andlinger, Chairman and Chief Executive Officer of NetOptix, issued
January 26, 1999, has been exercised.

of all or any significant portion of the assets or more than 10% of its common

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

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.

prior to the effective time:

    - by mutual consent of Corning and NetOptix;

    - by either company if the transaction is not completed on or prior to
      July 31, 2000, so long as the terminating party is not otherwise in
      material breach of its representations, warranties or obligations under
      the merger agreement;

    - by NetOptix at any time prior to the special meeting, upon five business
      days' notice to Corning, if the NetOptix board of directors approves a

         agreements as to competing proposals described 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 a superior proposal; and

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

         the merger in a manner adverse to Corning;

       - the NetOptix board of directors recommends to the shareholders of
         NetOptix a superior proposal; or

       - NetOptix enters into negotiations with any person concerning a

      approval;

    - by either company upon the other company's breach which has not been
      cured, subject to any materiality thresholds, of a representation,

      becomes untrue; or

    - by either company if a court of competent jurisdiction has taken any final
      and non-appealable action prohibiting the consummation of the merger.

    NetOptix will be required to pay a termination fee of $50 million under the
following circumstances:

    - Corning terminates the merger agreement because the NetOptix board of
      directors recommends to the NetOptix shareholders a superior proposal or
      NetOptix enters into negotiations with any

                                       44
<PAGE>
      person concerning a competing proposal in violation of the no solicitation
      of transactions provision in the merger agreement.

    - NetOptix terminates the merger agreement based on a superior proposal.

    NetOptix is also required to pay Corning $50 million if:

    - either company terminates the merger agreement as a result of the NetOptix
      stockholders failing to adopt the merger agreement;

      of NetOptix or a substantial part of its business or properties had been
      made public or known to NetOptix stockholders generally at or prior to the

    - within 12 months after termination, NetOptix consummates or enters into an
      agreement with respect to an acquisition proposal.

    NetOptix is also required to pay Corning $50 million if:

    - Corning terminates the merger agreement in accordance with the provisions
      set forth above providing for termination solely at its election at any
      time;

    - at any time after the date of the merger agreement and prior to 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 to an acquisition
      proposal.

    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

NetOptix, there shall be no liability on the part of NetOptix, Corning or CI
Subsidiary, Inc. except to the extent NetOptix is required to pay the

                     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 years. Any acquired in-process
    research and development will be 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
defined business operating segments: Telecommunications, Advanced Materials and
Information Display. Corning's business strategy is to focus on attractive
global markets where its leadership in materials and process technology will
allow it to achieve and sustain competitive advantage and superior growth over
time. Corning's principal executive offices are located at One Riverfront Plaza,
Corning, NY 14831 and its telephone number is (607) 974-9000.

    TELECOMMUNICATIONS.  Corning's Telecommunications segment produces optical
fiber and cable, optical hardware and equipment and photonics components for the
worldwide telecommunications industry. Corning offers a wide selection of fibers
for use in long-haul, utility, submarine, local exchange, cable TV and premises
applications. Corning provides a substantial portion of the world's optical
fiber, including LEAF-Registered Trademark- optical fiber, a technologically
advanced high speed, high-data-rate fiber.

    Siecor Corporation and Corning Cables, Corning's European optical fiber
cabling division, manufactures fiber-optic cable and network hardware that is
deployed throughout the world.

    Corning's Photonics Technologies Division provides products that maximize
the capacity, flexibility, performance and reliability of communications
networks worldwide. Corning's photonics products boost, combine, separate and
connect optical signals transmitted over fiber-optic telecommunications
networks. Corning is a leading supplier of optical amplifiers and was among the
first to offer an innovative multiplexer module that allows optical signals to
be added or dropped as they travel through a communications network.

    Photonics products, primarily intended to enable the use of dense wavelength
division multiplexing technology, include cutting-edge PureGain-TM- EDFA
modules, PureGain DCM-Registered Trademark- modules and PurePass-TM- optical
routing modules. Corning also offers MultiClad-Registered Trademark- couplers,
variable optical attenuators, micro-optic filters and PureMode-TM- engineered
fibers. Corning's optical networking products operate in terrestrial and
submarine networks worldwide, and are designed to withstand a wide array of
mechanical and environmental conditions. Corning is recognized as an industry
leader, providing low-cost, innovative fiber and photonic network solutions.
Corning's test facilities assure the performance and reliability of its
photonics products at both the component and system levels.

    ADVANCED MATERIALS.  Corning's Advanced Materials segment, which
manufactures environmental products, science products, semiconductor materials,
optical and lighting products and glass ceramic cooktops, has been a mainstay of
Corning's growth for decades.

    Corning's cellular ceramic products are component parts of catalytic
converters on cars, trucks and buses worldwide. Virtually every vehicle
manufacturer around the world demands new products that reduce emissions as
mandated by global, clean-air legislation. Recently introduced advanced cellular
ceramic products are expected to enable vehicle manufacturers to achieve
substantially reduced emissions over the next decade. Similar technologies are
used to reduce emissions from stationary power plants.

    New products from Corning's Science Products Division, which include polymer
microplates and which stem from its expertise in complex polymers, surface
chemistry and molecular biology, are useful in pharmaceutical and genomic
research. Corning's advanced microplates allow for more efficient drug testing.

                                       50
<PAGE>
    Corning's fused silica products enable semiconductor manufacturers to use
microlithography techniques to achieve miniaturization required for the
manufacture and processing of chips for computer applications.

    INFORMATION DISPLAY.  The Information Display segment manufactures glass
panels and funnels for televisions and cathode-ray tubes; projection video lens
assemblies; and liquid crystal display glass for flat panel displays. Corning is
a leading supplier of flat glass used in active matrix liquid crystal displays
for notebook computer screens, desktop monitors, digital cameras, personal
digital assistants and automotive displays. Ultra-thin, precision-surface glass
enables customers to create faster, larger and less expensive liquid crystal
displays that have higher resolution.

    Corning's lenses, which are used widely in projection television systems,
are being adapted to meet emerging requirements in digital and high-definition
systems for entertainment as well as commercial applications. Corning's
traditional, more mature television glass business concentrates on glass face
plates, panels, and funnels used to make color picture tubes.

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

RECENT DEVELOPMENTS

    Corning announced on March 16, 2000, that based on its strong results
through February, Corning expects to report first-quarter earnings before
special items in the range of $0.53 to $0.55 per share, approximately 50% ahead
of 1999 first-quarter earnings of $0.36. Corning also announced that it expects
to report full-year 2000 earnings before special items and before consideration
of the acquisition of NetOptix of approximately $2.45.

    Special charges related to the acquisition of Oak Industries and British
Telecommunications' Photonics Technology Research Center will be included in
Corning's first-quarter results. These items will reduce reported first-quarter
and full year results by approximately $70 million after tax, or $0.25 per
share.

    The NetOptix acquisition will be accounted for as a purchase and will not
impact Corning's results until the transaction is completed in the second
quarter. Excluding the amortization of goodwill and other acquired intangible
assets, the effect of the NetOptix acquisition is expected to be mildly dilutive
to Corning's earnings per share in 2000 and accretive in 2001 and thereafter.
Corning is currently studying the impact of purchase accounting for the NetOptix
acquisition and expects the useful life of goodwill and other acquired
intangibles to range from seven to ten years. Any acquired in-process research
and development will be expensed in the period the transaction is completed. On
an annual basis amortization of goodwill and purchased intangibles could reduce
Corning's earnings by up to $200 to $300 million after tax.

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 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.

                      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.

                                       53
<PAGE>
RIGHTS AGREEMENT

    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 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 53 and 54 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.

                                       55
<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.

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

                                       56
<PAGE>
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.

                                 LEGAL MATTERS

    Certain legal matters with respect to the validity of the securities offered
hereby will be passed upon for Corning by William D. Eggers, its Senior Vice
President and General Counsel, and the federal income tax consequences of the

                              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

                                      A-3
<PAGE>
    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,
    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 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

                                      A-4
<PAGE>
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.

    (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

                                      A-5
<PAGE>
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

duly organized, validly existing and in good standing under the laws of the
State of Delaware. Each of the Subsidiaries (as defined below) is a corporation

jurisdiction of its formation. Each of the Company and its Subsidiaries has the
requisite corporate power and authority to carry on its business as it 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 complete and correct copy of the certificate of
incorporation and by-laws, each as amended to the date hereof, of the Company
and each of its Subsidiaries.

    Section 4.2  CAPITALIZATION.  The authorized capital stock of the Company

Company Common Stock were reserved for future issuance pursuant to an
outstanding unexercised warrant ("Andlinger Capital Warrant"), and (d) no shares
of the Company Preferred Stock were outstanding. As of the date of this
Agreement, no shares of capital stock of the Company or any of its subsidiaries
have been issued since January 31, 2000 except pursuant to Company Stock Options

arrangements, calls, commitments or rights of any kind relating to the issued or
unissued capital stock of the Company or any of its subsidiaries or obligating
the Company or any of its Subsidiaries to issue or sell any shares of capital
stock of, or other equity interests in, the Company or any of its Subsidiaries.
All shares of capital stock of the Company and its Subsidiaries subject to
issuance pursuant to the Company Stock Option Plans, the ESPP and the Andlinger
Capital Warrant, upon issuance on the terms and conditions specified in the
instruments pursuant to which they are issuable, will be duly authorized,
validly issued, fully paid and non-assessable. As of the date of this Agreement,
there are no outstanding contractual obligations of the Company or any

necessary power and authority to execute and deliver this Agreement and the
Related Agreement, to perform its obligations hereunder and to consummate the
Merger and the other transactions contemplated by such agreements (the
"Transactions"). The execution and delivery of this Agreement by the Company and
the consummation by the Company of the Merger and the other Transactions have
been duly and validly authorized by all necessary corporate action and no other
corporate proceedings on the part of the Company are necessary to authorize the
execution and delivery of this Agreement and the Related Agreement or to

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 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,

                                      A-8
<PAGE>
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

(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

Effect, nor is there any judgment, decree, injunction or order of any
Governmental Entity or arbitrator outstanding against the Company or any of its

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,

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

(iii) any split, combination or reclassification of any of the Company's capital

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

(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

severance or termination pay, except as required under employment, severance or
termination agreements or plans in effect as of

                                      A-9
<PAGE>
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 ("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,

                                      A-10
<PAGE>
would cause the loss of such qualification or the imposition of any material
liability, penalty or tax under ERISA or the Code.

    (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.

    (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

                                      A-11
<PAGE>
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 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,

                                      A-12
<PAGE>
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, 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
thereto, with respect to (a) any Company Intellectual Property Rights (as
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
Subsidiaries where the obligation of the Company is in excess of $250,000 in the
aggregate in any year, (c) agreements or commitments with respect to capital
expenditures in excess of $100,000, (d) employment or compensation arrangements
or agreements with officers and directors of the Company and any employee
earning in excess of $50,000 per year, and (e) all agreements and instruments
evidencing obligations for borrowed money or agreements between the Company and
its Affiliates, are listed in the Company Disclosure Schedule (collectively, the
"Material Contracts"). The Company has delivered to Buyer true and accurate
copies of the Company Material Contracts. All such Company Material Contracts
are valid and binding and are in full force and effect and enforceable against
the Company or its Subsidiaries in accordance with their respective terms. Other
than contracts included in the Company Material Contracts, none of the Company's
contracts which are material individually or in the aggregate provide for
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

                                      A-13
<PAGE>
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 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 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

                                      A-14
<PAGE>
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.

    Section 4.18  UNDISCLOSED LIABILITIES.  Except as disclosed in the Company's
Annual Report on Form 10-K for the fiscal year ended September 30, 1999 (or in
any subsequently filed Company SEC Reports), as of the date hereof, neither the
Company nor any of its Subsidiaries has any liabilities or any 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 Governmental
Entity with respect to the Company or any of its Subsidiaries is pending or
threatened, nor has any such Governmental Entity indicated an intention to

announcement with respect to such transactions during such period, and Buyer and
the Company shall, to the extent practicable, allow the other party reasonable

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

incurred such Indemnified Party's legal and other expenses (including the cost
of any investigation and preparation) incurred in connection therewith. The

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 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.

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
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

                                      B-1
<PAGE>
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 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.
                                          SALOMON SMITH BARNEY INC.

    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 consummation of the transactions

                                      C-3
<PAGE>
    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 the Trust) requires the
    consent of any beneficiary for the execution and delivery of this Agreement
    or for the consummation of the transactions contemplated hereby.

        (d)  THE SHARES BENEFICIALLY OWNED.  Each Stockholder is the record and
    beneficial owner of, is the sole manager of the record owner of or is the
    trustee that is the record holder of, and whose beneficiaries are the
    beneficial owners of, and has good and valid title to and sole voting and
    dispositive power to, the Shares set forth under its or his name on the
    signature pages attached hereto, free and clear of any claims, liens,
    encumbrances, security interests, options, charges and restrictions of any
    kind. 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,

                                      C-4
<PAGE>
    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 fees are
    payable by NetOptix, no broker, investment banker, financial advisor or
    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
take the necessary steps to promptly inform the individuals or entities 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

his or its counsel reviewed and negotiated the terms and provisions of this
Agreement and 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

    (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

policy, all other conditions and provisions of this Agreement shall nevertheless
