</TABLE>
(1) Associated with the Common Stock are Preferred Share Purchase Rights that 
will not be exercisable or evidenced separately from the Common Stock prior 
to the occurrence of certain events. 

(2) Based upon the maximum number of shares of Corning Common Stock issuable 
in the Merger to holders of shares of Nichols Common Stock and Nichols 
Preferred Stock, assuming exercise of all outstanding options and warrants to 
acquire Nichols Common Stock and based on a price per share of Corning Common 
Stock of $26.50, which results in the highest Exchange Ratio (as defined in 
the Merger Agreement) possible under the Merger Agreement. 

(3) The registration fee was computed pursuant to rule 457(f) under the 
Securities Act of 1933, as amended (the "Securities Act"), based upon the 
maximum value of $13 in shares of Corning Common Stock to be paid per share 
of Nichols Common Stock in the Merger, and the value of $350 plus accrued 
dividends in shares of Corning Common Stock to be paid per share of Nichols 
Preferred Stock in the Merger. 

(4) Pursuant to Rule 457(b) under the Securities Act and Section 14(g) of the 
Securities Exchange Act of 1934, as amended, and Rule 0-11 thereunder, the 
total registration fee of $89,164 is offset by the filing fee of $44,441 
previously paid by Nichols in connection with the filing of preliminary proxy 
materials on June 24, 1994. Accordingly, the fee payable upon the filing of 
this Registration Statement is $44,723. 

The Registrant hereby amends the Registration Statement on such date or dates 
as may be necessary to delay its effective date until the Registrant shall 
file a further amendment which specifically states that this Registration 
Statement shall thereafter become effective in accordance with Section 8(a) 
of the Securities Act, or until the Registration Statement shall become 
effective on such date as the Commission, acting pursuant to said Section 
8(a), may determine.

Dear Fellow Stockholder: 

You are cordially invited to attend the Special Meeting of Stockholders (the 
"Special Meeting") of Nichols Institute ("Nichols"), which will be held on 
Wednesday, August 31, 1994 at 9:30 a.m., local time, at 33608 Ortega Highway, 
San Juan Capistrano, CA 92690, Building A. 

At the Special Meeting, holders of Class A Common Stock and Class B Common 
Stock of Nichols will be asked to consider and vote upon a proposal to adopt 
an Agreement and Plan of Merger among Nichols, Corning Incorporated 
("Corning") and a subsidiary of Corning (the "Merger Agreement"), with 
respect to the merger of the Corning subsidiary into Nichols as provided for 
in the Merger Agreement (the "Merger"). Holders of Class C Common Stock and 
Series E Convertible Preferred Stock of Nichols are not entitled to vote on 
the Merger and are being provided the accompanying Notice of Special Meeting 
of Stockholders and Proxy Statement/Prospectus for informational purposes 
only. In the Merger, each outstanding share of the Class A Common Stock, the 
Class B Common Stock and the Class C Common Stock of Nichols (together, the 
"Nichols Common Stock") and each share of Series E Convertible Preferred 
Stock of Nichols (but excluding shares of Class B Common Stock and Series E 
Convertible Preferred Stock as to which appraisal rights shall have been 
perfected) will be converted into shares of the common stock of Corning, as 
described in the accompanying Proxy Statement/Prospectus, and Nichols will 
become a wholly owned subsidiary of Corning. Stockholders will receive cash 
in lieu of any fractional shares. 

You should read carefully the accompanying Notice of Special Meeting of 
Stockholders and the Proxy Statement/Prospectus for details of the Merger and 
additional related information. 

NICHOLS' BOARD OF DIRECTORS HAS DETERMINED THE MERGER TO BE FAIR TO AND IN 
THE BEST INTERESTS OF NICHOLS AND ITS STOCKHOLDERS, HAS UNANIMOUSLY APPROVED 
THE MERGER AGREEMENT AND RECOMMENDS A VOTE FOR ADOPTION OF THE MERGER 
AGREEMENT. 

The affirmative vote of the holders of shares representing a majority of the 
outstanding voting power of the Nichols Common Stock is necessary to adopt 
the Merger Agreement. I am the beneficial owner of shares of Nichols Common 
Stock having an aggregate of approximately 60% of the voting power of the 
Nichols Common Stock, and I have agreed to vote my shares in favor of the 
Merger Agreement. Accordingly, adoption thereof by the Nichols stockholders 
is assured. 

Whether or not you plan to attend the Special Meeting, please complete, sign 
and date the enclosed proxy card and return it promptly in the enclosed 
postage-prepaid envelope. If you attend the Special Meeting, you may vote in 
person if you wish, even though you previously have returned your proxy card. 
Your prompt cooperation will be greatly appreciated. 

Please do not send your share certificates with your proxy card. After 
adoption of the Merger Agreement by the Nichols stockholders and satisfaction 
of all other conditions to the Merger, you will receive a transmittal form 
and instructions for the surrender and exchange of your shares. 

Sincerely, 
Albert L. Nichols, M.D. 
Chairman of the Board 

       PLEASE COMPLETE, SIGN, DATE AND RETURN THE ENCLOSED PROXY CARD.

Nichols, Corning Incorporated, a New York corporation ("Corning"), and Apple 
Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of 
Corning ("Merger Sub"), with respect to the merger of Merger Sub into Nichols 
upon the terms and subject to the conditions thereof (the "Merger"). Pursuant 
to the Merger Agreement, Nichols will become a wholly owned subsidiary of 
Corning, and each share of Class A Common Stock (the "Class A Common Stock"), 
par value $.10 per share, Class B Common Stock (the "Class B Common Stock"), 
par value $.10 per share, and Class C Common Stock (the "Class C Common 
Stock"), par value $.10 per share, of Nichols (together, the "Nichols Common 
Stock") issued and outstanding at the effective time of the Merger (other 
than shares of Class B Common Stock as to which appraisal rights shall have 
been perfected) shall be converted into the right to receive that number (the 
"Exchange Ratio") of shares of Corning's common stock, par value $.50 per 
share (each a "Corning Common Share"), equal to the quotient derived by 
dividing $13.00 by the average of the closing prices on the New York Stock 
Exchange per Corning Common Share during the 10 consecutive trading days 
ending on the fifth trading day prior to the Special Meeting; provided, 
however, that in no event will the Exchange Ratio be greater than 0.491. Each 
share of Nichols' Series E Convertible Preferred Stock ("Nichols Preferred 
Stock") (other than shares of Nichols Preferred Stock as to which appraisal 
rights shall have been perfected) shall be converted in the Merger into 
Corning Common Shares in the manner and amount provided for pursuant to the 
terms of the Nichols Preferred Stock. Each Corning Common Share issued in the 
Merger shall be accompanied by one right (a "Right") to purchase, on the 
occurrence of certain events, Corning Common Shares or Series A Preferred 
Stock of Corning, unless the Rights shall not be outstanding as of the 
effective time of the Merger. The Merger is more completely described in the 
accompanying Proxy Statement/Prospectus, and a copy of the Merger Agreement 
is attached as Appendix A thereto. 

 2. To transact such other matters relating to the conduct of the Special 
Meeting or any adjournments or postponements thereof that may properly come 
before the Special Meeting. 

Only holders of record of shares of the capital stock of Nichols at the close 
of business on July 29, 1994, the record date for the Special Meeting, are 
entitled to notice of, and only holders of shares of Class A Common Stock and 
Class B Common Stock at the close of business on July 29, 1994 are entitled 
to vote at, the Special Meeting and any adjournments or postponements 
thereof. 

The affirmative vote of the holders of shares representing a majority of the 
outstanding voting power of the Nichols Common Stock is necessary to adopt 
the Merger Agreement. Dr. Albert L. Nichols, the beneficial owner of shares 
of Nichols Common Stock having an aggregate of approximately 60% of the 
voting power of the Nichols Common Stock, has agreed to vote in favor of the 
Merger Agreement. Accordingly, adoption thereof by the Nichols stockholders 
is assured. 

Holders of Class A Common Stock and Class C Common Stock will not be entitled 
to appraisal rights as a result of the Merger. Under Delaware law, appraisal 
rights are unavailable to holders of the Class A Common Stock and the Class C 
Common Stock because the Class A Common Stock and the Class C Common Stock 
were, on the record date, listed on the American Stock Exchange and will be 
converted into Corning Common Shares, which at the effective time of the 
Merger will be listed on the New York Stock Exchange. Holders of record of 
Class B Common Stock and Nichols Preferred Stock who comply with the 
statutory requirements will be entitled, under Section 262 of the General 
Corporation Law of the State of Delaware, to demand appraisal of their shares 
of Class B Common Stock and Nichols Preferred Stock if the Merger Agreement 
is adopted and the Merger is consummated. A summary of the provisions of 
Section 262, including a summary of the requirements with which stockholders 
demanding such appraisal must comply, is contained in the Proxy 
Statement/Prospectus under the heading "THE MERGER--Appraisal Rights for 
Unlisted Stock Only." The entire text of Section 262 is attached as Appendix 
D to the accompanying Proxy Statement/Prospectus.

                    COMMON STOCK, PAR VALUE $.50 PER SHARE 
                              NICHOLS INSTITUTE 
                               PROXY STATEMENT 

                   FOR A SPECIAL MEETING OF STOCKHOLDERS OF 
                              NICHOLS INSTITUTE 
                        TO BE HELD ON AUGUST 31, 1994 

Nichols Institute, a Delaware corporation ("Nichols"), is furnishing this 
Proxy Statement/Prospectus to its stockholders in connection with the 
solicitation of proxies by the Board of Directors of Nichols (the "Nichols 
Board") for use at its Special Meeting of Stockholders and at any 
adjournments or postponements thereof (the "Special Meeting"). 

At the Special Meeting, holders of voting stock of Nichols will consider and 
vote upon a proposal to adopt an Agreement and Plan of Merger, dated as of 
June 1, 1994, as amended (the "Merger Agreement"), among Nichols, Corning 
Incorporated, a New York corporation ("Corning"), and Apple Acquisition 
Corp., a Delaware corporation and a wholly owned subsidiary of Corning 
("Merger Sub"), with respect to the merger of Merger Sub into Nichols upon 
the terms and subject to the conditions thereof (the "Merger"). In the 
Merger, Nichols will become a wholly owned subsidiary of Corning, and each 
outstanding share of Class A Common Stock (the "Class A Common Stock"), par 
value $.10 per share, Class B Common Stock (the "Class B Common Stock"), par 
value $.10 per share, and Class C Common Stock (the "Class C Common Stock"), 
par value $.10 per share, of Nichols (together, the "Nichols Common Stock") 
(other than shares of Class B Common Stock as to which appraisal rights shall 
have been perfected) shall be converted into the right to receive that number 
(the "Exchange Ratio") of shares of Corning's common stock, par value $.50 
per share (each a "Corning Common Share"), equal to the quotient derived by 
dividing $13.00 by the average of the closing prices on the New York Stock 
Exchange, Inc. (the "NYSE") per Corning Common Share during the 10 
consecutive trading days ending on the fifth trading day prior to the Special 
Meeting; provided, however, that in no event will the Exchange Ratio be 
greater than 0.491. Each share of Nichols' Series E Convertible Preferred 
Stock ("Nichols Preferred Stock") (other than shares of Nichols Preferred 
Stock as to which appraisal rights shall have been perfected) shall be 
converted in the Merger into Corning Common Shares in the manner and amount 
provided for pursuant to the terms of the Nichols Preferred Stock. Each 
Corning Common Share issued in the Merger shall be accompanied by one right 
(a "Right") to purchase, on the occurrence of certain events, Corning Common 
Shares or Series A Preferred Stock of Corning, unless the Rights shall not be 
outstanding as of the effective time of the Merger. See "THE MERGER--Effect 
on Capital Stock." 

Dr. Albert L. Nichols, the beneficial owner of shares of Nichols Common Stock 
having an aggregate of approximately 60% of the voting power of the Nichols 
Common Stock, has agreed to vote in favor of the adoption of the Merger 
Agreement. Accordingly, adoption thereof by the Nichols stockholders is 
assured. 

No fractional Corning Common Shares will be issued in the Merger. In lieu of 
any such fractional shares, each holder of Nichols Common Stock who otherwise 
would be entitled to receive a fractional Corning Common Share pursuant to 
the Merger will be paid an amount in cash, without interest, equal to such 
holder's proportionate interest in the net proceeds from the sale or sales in 
the open market by the Exchange Agent for the Merger, Harris Trust and 
Savings Bank, on behalf of all such holders, of the aggregate fractional 
Corning Common Shares, if any, that would have been issued in the Merger. 

This Proxy Statement/Prospectus is first being mailed to Nichols stockholders 
on or about August   , 1994. 

THE CORNING COMMON SHARES ISSUABLE IN THE MERGER HAVE NOT BEEN APPROVED OR 
DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES 
COMMISSION NOR HAS THE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED 
UPON THE ACCURACY OR ADEQUACY OF THIS PROXY STATEMENT/PROSPECTUS. ANY 
            REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE. 

       The date of this Proxy Statement/Prospectus is August   , 1994. 

This Proxy Statement/Prospectus constitutes the Prospectus of Corning filed 
as part of a Registration Statement on Form S-4 (the "Registration

                                           appraisal rights shall have been perfected) shall be 
                                           converted into the right to receive that number (the 
                                           Exchange Ratio) of Corning Common Shares equal to the 
                                           quotient derived by dividing $13.00 by the average of the 
                                           closing prices on the NYSE per Corning Common Share (as 
                                           reported in the NYSE Composite Transactions) during the 
                                           10 consecutive trading days ending on the fifth trading 
                                           day prior to the Special Meeting; provided, however, that 
                                           in no event will the Exchange Ratio be greater than 
                                           0.491. Each share of Nichols' Preferred Stock (other than 
                                           shares of Nichols Preferred Stock as to which appraisal 
                                           rights shall have been perfected) shall be converted in 
                                           the Merger into Corning Common Shares in the manner and 
                                           amount provided for pursuant to the terms of the Nichols 
                                           Preferred Stock. See "DESCRIPTION OF NICHOLS 
                                           STOCK--Preferred Stock." Each Corning Common Share issued 
                                           in the Merger shall be accompanied by one Right unless 
                                           the Rights shall not be outstanding as of the Effective 
                                           Time. If, prior to the Effective Time, Corning should 
                                           split or combine the Corning Common Shares, or pay a 
                                           stock dividend or other stock distribution in Corning 
                                           Common Shares, or otherwise change the Corning Common 
                                           Shares into any other securities, or make any other 
                                           dividend or distribution on the Corning Common Shares 
                                           (other than normal quarterly dividends as the same may be 
                                           adjusted from time to time in the ordinary course), then 
                                           the Exchange Ratio will be appropriately adjusted to 
                                           reflect such split, combination, dividend or other 
                                           distribution or change. In the event the Exchange Ratio, 
                                           calculated as set forth above, without giving effect to 
                                           the proviso, would equal or be greater than 0.638, then 
                                           Nichols may terminate the Merger Agreement but it is not 
                                           obligated to do so. See "Certain Significant 
                                           Considerations."

Fractional Shares                          No fractional Corning Common Shares will be issued in the 
                                           Merger. In lieu of any such fractional shares, each 
                                           holder of Nichols Common Stock who otherwise would be 
                                           entitled to receive a fractional Corning Common Share 
                                           pursuant to the Merger will be paid an amount in cash, 
                                           without interest, equal to such holder's proportionate 
                                           interest in the net proceeds from the sale or sales in 
                                           the open market by Harris Trust and Savings Bank, the 
                                           exchange agent for the Merger (the "Exchange Agent"), on 
                                           behalf of all such holders, of the aggregate fractional 
                                           Corning Common Shares, if any, that would have been 
                                           issued in the Merger. As soon as practicable following 
                                           the Effective Time, the Exchange Agent will determine the 
                                           excess, if any, of (i) the number of full Corning Common 
                                           Shares delivered to the Exchange Agent by Corning over 
                                           (ii) the aggregate number of whole Corning CommonShares 
                                           to be distributed to holders of Nichols Common Stock 
                                           (such excess being herein called the "Excess Shares"), 
                                           and the Exchange Agent, as agent for the former holders 
                                           of Nichols Common Stock, will sell any such Excess Shares 
                                           at the prevailing prices on the NYSE, in round lots to 
                                           the extent practicable. See "THE MERGER--Terms of the 
                                           Merger." 

Recommendation of the Nichols 
   Board                                   The Nichols Board has determined the Merger to be fair to 
                                           and in the best interests of Nichols and its stockholders 
                                           and has unanimously approved the Merger Agreement. The 
                                           Nichols Board recommends that Nichols stockholders adopt 
                                           the Merger Agreement. The Nichols Board's recommendation 
                                           is based upon a number of factors discussed in this Proxy 
                                           Statement/Prospectus. See "BACKGROUND AND REASONS FOR THE 
                                           MERGER; RECOMMENDATION OF THE NICHOLS BOARD--Nichols' 
                                           Reasons for the Merger; Recommendation of the Nichols 
                                           Board."

                                           rendered an opinion to the Nichols Board to the effect 
                                           that, as of June 1, 1994, the consideration to be 
                                           received by Nichols stockholders in connection with the 
                                           proposed Merger is fair to such stockholders from a 
                                           financial point of view. A copy of the opinion of CS 
                                           First Boston, dated June 1, 1994, setting forth the 
                                           assumptions made, the matters considered and the 
                                           limitations on the review undertaken in rendering such 
                                           opinion, is attached to this Proxy Statement/Prospectus 
                                           as Appendix C, and should be read carefully in its

                                           the conditions to the Merger, the Merger will be 
                                           consummated and become effective at the time (the 
                                           "Effective Time") at which the certificate of merger to

Exchange of Certificates in the 
   Merger                                  Promptly after the Effective Time, the Exchange Agent 
                                           will mail a transmittal form and instructions to each 
                                           holder of record of certificates which immediately prior 
                                           to the Effective Time represented outstanding shares of 
                                           Nichols Common Stock or Nichols Preferred Stock, which 
                                           form and instructions are to be used in forwarding such 
                                           certificates for surrender and exchange for (i) 
                                           certificates representing that number of whole Corning 
                                           Common Shares that such holder has the right to receive 
                                           pursuant to the Merger and (ii) cash for any fractional 
                                           Corning Common Shares to which such holder otherwise 
                                           would be entitled. Nichols stockholders are requested not 
                                           to surrender their certificates for exchange until such 
                                           transmittal form and instructions are received. Holders

                                           distributions in respect of the certificates surrendered 
                                           in connection with the Merger will not be entitled to 
                                           receive interest on such dividends or other 
                                           distributions. See "THE MERGER--Effect on Capital

   Shares on the NYSE                      Authorization for the listing of the Corning Common 
                                           Shares to be issued pursuant to the Merger Agreement for 
                                           trading on the NYSE is a condition to the obligations of

Business of Nichols Pending the 
   Merger                                  Nichols has agreed that, prior to the Effective Time or 
                                           earlier termination of the Merger Agreement, except as 
                                           contemplated by the Merger Agreement, Nichols and its 
                                           subsidiaries will each conduct its operations according 
                                           to its ordinary course of business consistent with past 
                                           practice. In addition, unless Corning agrees in writing 
                                           or except as otherwise permitted pursuant to the Merger 
                                           Agreement or as previously disclosed to Corning, prior to 
                                           the Effective Time neither Nichols nor any of its 
                                           subsidiaries is permitted to engage in any of a number of 
                                           actions specified in the Merger Agreement. See "THE 
                                           MERGER--Certain Covenants--Conduct of Business by 
                                           Nichols." 

No Solicitation                            Nichols has agreed that, prior to the Closing or earlier 
                                           termination of the Merger Agreement, neither Nichols nor 
                                           any of its officers, employees, representatives, agents 
                                           or affiliates will, directly or indirectly, encourage, 
                                           solicit or engage in discussions or negotiations with any 
                                           person (other than Corning) concerning any merger, 
                                           consolidation, share exchange or similar transaction, any 
                                           purchase of substantial assets or equity of Nichols or 
                                           its significant subsidiaries, or any other transaction 
                                           that would involve the transfer or potential transfer of 
                                           control of Nichols, other than the transactions 
                                           contemplated by the Merger Agreement. See "THE

   Nichols after the Merger                After the Merger, Nichols will be a wholly owned 
                                           subsidiary of Corning. Nichols will operate as one of

Conditions of the Merger; 
   Termination                             The consummation of the Merger is conditioned upon the 
                                           fulfillment or waiver (where permissible) of certain 
                                           conditions set forth in the Merger Agreement. See "THE 
                                           MERGER--Closing Conditions." The Merger Agreement may be 
                                           terminated (i) by mutual consent of Corning and Nichols, 
                                           (ii) by either Corning or Nichols if the Merger has not 
                                           been consummated by November 30, 1994 and (iii) under 
                                           certain other circumstances. In the event the Exchange 
                                           Ratio, as calculated, would equal or be greater than 
                                           0.638, then Nichols may terminate the Merger Agreement, 
                                           but it is not obligated to do so. See "THE 
                                           MERGER--Closing Conditions" and "-- Amendment; 
                                           Termination."

   Favor of the Merger                     Concurrently with the execution of the Merger Agreement, 
                                           Corning and Dr. Albert L. Nichols entered into a letter 
                                           agreement dated June 1, 1994 (the "Dr. Nichols Letter 
                                           Agreement"), pursuant to which Dr. Nichols has agreed to 
                                           vote all shares of Nichols Common Stock that he has the 
                                           right to vote in favor of the adoption of the Merger 
                                           Agreement at the Special Meeting. As ofJuly 27, 1994, Dr. 
                                           Nichols had the power to vote shares representing 
                                           approximately 60% of the voting power of the Nichols 
                                           Common Stock. Accordingly, adoption of the Merger 
                                           Agreement by the Nichols stockholders is assured. See 
                                           "THE MERGER--Agreement of Dr. Nichols to Vote in Favor of 
                                           the Merger." 

Certain Federal Income Tax 
   Consequences                            It is expected that the Merger will constitute a 
                                           reorganization for federal income tax purposes and, 
                                           accordingly, that no gain or loss will be recognized by 
                                           holders of Nichols Common Stock upon the conversion of 
                                           Nichols Common Stock solely into Corning Common Shares in 
                                           the Merger (except with respect to any cash received in 
                                           lieu of a fractional share interest in Corning Common 
                                           Shares). See "THE MERGER--Certain Federal Income Tax 
                                           Consequences." Nichols stockholders are urged to consult 
                                           their own tax advisors as to the specific tax 
                                           consequences to them of the Merger. 

Regulatory Approvals                       In connection with the Merger, Corning, Nichols and Dr. 
                                           Nichols have made filings or applications with the 
                                           Federal Trade Commission (the "FTC") and the Antitrust 
                                           Division of the Department of Justice (the "Antitrust 
                                           Division") pursuant to the Hart-Scott-Rodino Antitrust 
                                           Improvements Act of 1976, as amended, and the rules 
                                           promulgated thereunder (the "HSR Act"). Consummation of 
                                           the Merger is conditioned upon, among other things, 
                                           expiration of the waiting periods under the HSR Act and 
                                           the receipt of other necessary regulatory approvals. The 
                                           waiting periods under the HSR Act have expired. See "THE 
                                           MERGER--Regulatory Approvals" and "--Closing Conditions." 

Accounting Treatment                       It is expected that the Merger will be accounted for as a 
                                           pooling of interests. It is a condition to the obligation 
                                           of Corning to consummate the Merger that Corning receive 
                                           the opinion of Price Waterhouse that the Merger can be 
                                           accounted for as a pooling of interests. See "THE 
                                           MERGER--Accounting Treatment."

Interests of Certain Persons in the 
   Merger                                  In the Merger Agreement, Corning agreed to assume all 
                                           outstanding options granted under Nichols' stock option 
                                           plans. Each of Nichols' executive officers, including Dr. 
                                           Nichols and Messrs. Bragg and Bellamy, who are also 
                                           directors of Nichols, holds options, and Nichols' other 
                                           directors hold options. Upon the execution of the Merger 
                                           Agreement, the vesting schedule of certain options to 
                                           purchase shares of Class A Common Stock and Class C 
                                           Common Stock held by, among others, certain Nichols 
                                           executive officers (including certain directors) 
                                           accelerated. Also, if the Merger is consummated, and 
                                           subject in some cases to the satisfaction of certain 
                                           other conditions, vesting of options to purchase Class C 
                                           Common Stock held by certain Nichols executive officers, 
                                           including certain directors, will accelerate. 

                                           Also in connection with the Merger, effective as of the 
                                           Closing Date, Nichols will enter into an employment 
                                           agreement with Dr. Nichols pursuant to which Dr. Nichols 
                                           will serve as Chairman Emeritus of Nichols for a term of 
                                           two years, which term may be extended for an additional 
                                           three years by agreement between the parties. Dr. Nichols 
                                           will serve on the Board of Directors of CLSI and will 
                                           have special responsibility for strategic planning. See 
                                           "THE MERGER--Interests of Certain Persons in the Merger." 

                                           In connection with the Merger, as of the Closing Date 
                                           certain executive officers of Nichols will enter into new 
                                           employment contracts with Nichols. See "THE 
                                           MERGER--Interests of Certain Persons in the Merger." 
Appraisal Rights for Unlisted 
   Stock Only                              Under the DGCL, holders of Class A Common Stock and Class 
                                           C Common Stock will not be entitled to appraisal rights 
                                           as a result of the Merger. 

                                           Under the DGCL, record holders of the Class B Common

                                           Merger Agreement and record holders of Nichols Preferred 
                                           Stock, in each case who properly demand appraisal of 
                                           their shares with respect to the Merger (the "Dissenting 
                                           Holders") have the right to obtain a cash payment for the 
                                           "fair value" of their shares of Class B Common Stock and 
                                           Nichols Preferred Stock, respectively (excluding any 
                                           element of value arising from the accomplishment or 
                                           expectation of the Merger). In order to exercise such 
                                           rights, Dissenting Holders must deliver to Nichols, prior 
                                           to the vote on the Merger Agreement at the Special 
                                           Meeting, a written demand for appraisal and must comply 
                                           with the other procedural requirements of Section 262 of 
                                           the DGCL, a description of which is provided under "THE 
                                           MERGER--Appraisal Rights for Unlisted Stock Only" and the

                                           Statement/Prospectus as Appendix D. 

                                           Such "fair value" (which could be more than, the same as 
                                           or less than the market value of the number of Corning

CERTAIN SIGNIFICANT CONSIDERATIONS 

In considering whether to vote in favor of adoption of the Merger Agreement, 
Nichols stockholders should consider the following: (i) the Exchange Ratio 
will be determined based on the average closing price of the Corning Common 
Shares over the 10 consecutive trading days ending on the fifth trading day 
prior to the date of the Special Meeting, and if that value is equal to or 
greater than $26.48 then Nichols stockholders would receive $13.00 worth of 
Corning Common Shares for each share of Nichols Common Stock, assuming that 
the value of the Corning Common Shares at the Effective Time equals the value 
used in calculating the Exchange Ratio; however, if the value used in 
calculating the Exchange Ratio is less than $26.48 then Nichols stockholders 
would receive less than $13.00 worth of Corning Common Shares for each share 
of Nichols Common Stock, assuming that the value of the Corning Common Shares 
at the Effective Time equals the value used in calculating the Exchange 
Ratio; (ii) if the value used in calculating the Exchange Ratio is equal to 
or less than $20.375, at which point (assuming that the value of the Corning 
Common Shares at the Effective Time equalled such value) the Nichols 
stockholders would receive less than $10.00 worth of Corning Common Shares 
for each share of Nichols Common Stock, Nichols may, but is not obligated to, 
terminate the Merger Agreement; and (iii) the price of the Corning Common 
Shares at the Effective Time can be expected to vary from the value used in 
calculating the Exchange Ratio as well as from its price as of the date of 
this Proxy Statement/Prospectus and the date on which the Nichols 
stockholders vote on the Merger Agreement due to changes in the business, 
operations or prospects of Corning, market assessments of the likelihood that 
the Merger will be consummated and the timing thereof, general market and 
economic conditions, and other factors. See "THE MERGER--Effect on Capital 
Stock" and "--Amendment; Termination" and "DIVIDENDS ON AND MARKET PRICES OF 
CORNING COMMON SHARES AND NICHOLS COMMON STOCK." 

                             RECENT DEVELOPMENTS 

On July 27, 1994, Nichols released its results for the quarter ended June 30, 
1994. Nichols incurred a second quarter 1994 net loss of $3.7 million, or 
$0.22 per share, compared to second quarter 1993 net income of $3.9 million, 
or $0.13 per share. Nichols' first half 1994 net loss totaled $5.3 million, 
or $0.31 per share, compared to first half 1993 net income of $4.4 million, 
or $0.25 per share. 

Revenues for the second quarter 1994 were $71.4 million, slightly ahead of 
second quarter 1993 revenues of $71.2 million. Revenues for first half 1994 
were $141.0 million, slightly behind first half 1993 revenues of $142.9 
million. 

The 1994 second quarter and first half results include approximately $4.5 
million and $6.3 million, respectively, of increased pre-tax expenditures 
related to the Merger, costs related to Nichols' proposed senior notes 
offering which was suspended upon announcement of the Merger (as described 
under "Background and Reasons for the Merger; Recommendation of the Nichols 
Board"), expenses related to responding to a subpoena from the Office of the 
Inspector General (as described under "Business of Nichols-OIG 
Investigation"), and certain contract revenue adjustments.

CERTAIN HISTORICAL AND PRO FORMA FINANCIAL DATA 

Comparative Unaudited Per Share Data 
The following table sets forth certain unaudited historical, pro forma and 
equivalent per share data for Corning as of and for the twenty-four weeks 
ended June 19, 1994, and as of and for the year ended January 2, 1994, and 
for Nichols as of and for the three months ended March 31, 1994, and as of 
and for the year ended December 31, 1993. 

For purposes of calculating equivalent share data, it has been assumed (for 
illustrative purposes only) that the Exchange Ratio is 0.394. This 
illustrative Exchange Ratio was calculated based upon an assumed price per 
Corning Common Share of $33.00. Variations in the actual Exchange Ratio 
pursuant to the Merger Agreement would not materially impact equivalent share 
data. 

The following data are derived from, and should be read in conjunction with, 
the historical consolidated financial statements of Corning and Damon, 
including the notes thereto, incorporated by reference into this Proxy 
Statement/Prospectus, and the historical consolidated financial statements of 
Nichols and the Corning Unaudited Pro Forma Combined Financial Information, 
including the notes thereto, contained elsewhere in this Proxy 
Statement/Prospectus. The pro forma financial data are presented for 
informational purposes only, and are not necessarily indicative of the 
results or financial position that actually would have occurred had the 
Merger and other transactions represented in the pro forma financial data 
been completed on the dates indicated or the results or financial position 
that may occur or be attained in the future.

Selected Historical Financial Data 
The following is a summary of certain consolidated financial information that 
has been derived from the consolidated financial statements of Corning and 
Nichols. The summary financial data set forth below for Corning and Nichols 
for the 1989 through 1993 fiscal years are derived from the audited financial 
statements of each company. The summary financial data set forth below for 
each company for the first quarter or the first half of 1994 are derived from 
their respective unaudited financial statements, which in the opinion of 
management of each such company contain all adjustments necessary for the 
fair presentation of this information. During the three months ended March 
31, 1994, Nichols incurred unusual charges of $1.8 million which consisted of 
$1.3 million in costs related to the "OIG Investigation" and $0.5 million in 
financing fees. The financial data should be read in conjunction with the 
historical statements and notes thereto, and related Management's Discussion 
and Analysis of Financial Condition and Results of Operations, of Corning 
which are incorporated by reference into this Proxy Statement/Prospectus and 
of Nichols which are included elsewhere in this Proxy Statement/Prospectus. 
Results for the first quarter or the first half of 1994 are not necessarily 
indicative of the results that may be expected for any other interim period 
or for the year as a whole.

(a) During 1992 and 1994, Nichols adopted the standards specified in 
Statements of Financial Accounting No. 109 "Accounting for Income Taxes" 
(SFAS 109) and No. 112 "Employers' Accounting for Postemployment Benefits" 
(SFAS 112), respectively. The adoption of SFAS 109 and SFAS 112 did not have 
a significant impact on previously reported amounts. 

(b) As of December 31, 1993 Nichols was not in compliance with certain 
covenants of its senior note agreements. The agreements provide that as a 
result of the failure to comply with the covenants, the holders of the senior 
notes have the right to declare the entire unpaid balance ($62.2 million) 
immediately due and payable. Accordingly, the senior notes have been 
classified as current, resulting in Nichols' reporting a working capital 
deficit as of December 31, 1993 and as of March 31, 1994. 

(c) Net income (loss) per common and common equivalent share is based on the 
weighted average number of shares of Nichols Common Stock and, in 1989, 1990 
and 1991 and the three months ended March 31, 1993, common equivalent shares 
outstanding during the period. Common equivalent shares relate to Class A 
Common Stock issuable upon the conversion of the Nichols Preferred Stock; 
upon the exercise of stock options and warrants and to be issued as future 
consideration for covenants not to compete. 

(d) In 1989, Nichols distributed a 5% stock dividend and then a 100% stock 
dividend. In 1990, Nichols distributed a 4% stock dividend. Per share 
information presented above has been adjusted to give retroactive effect to 
these dividends. 

(e) Book value per common share at December 31, 1991, 1992, and 1993 and 
March 31, 1993 and 1994 includes the impact of preferred stock liquidation 
preferences and treats outstanding shares of the Class A Common Stock, Class 
B Common Stock and Class C Common Stock as if they were shares of a single 
class of common stock.

Summary Unaudited Pro Forma Combined Financial Data 
The summary unaudited pro forma combined financial data set forth below 
reflect the estimated impact on Corning's financial statements of the 
proposed Merger, the acquisition of Damon, the merger with Costar Corporation 
("Costar"), the transaction with Unilab Corporation ("Unilab") and several 
other completed 1993 transactions, the Vitro S.A. ("Vitro") transaction in 
January 1994, the acquisition of the optical-fiber and optical-cable 
businesses of Northern Telecom Limited ("NTL") by Corning and Siecor 
Corporation ("Siecor") in February 1994, the merger with Maryland Medical 
Laboratory, Inc. ("Maryland Medical") completed in June 1994, and the 
offering of Convertible Monthly Income Preferred Securities of Corning 
Delaware, L.P. (the "MIPS Offering") completed in July 1994 (collectively, 
the "Corning Transactions"). See "BUSINESS OF CORNING--Recent Developments". 
Such pro forma data assume the Corning Transactions had been completed on 
January 4, 1993, for income statement data and by June 19, 1994, for balance 
sheet data. Corning's consolidated financial statements for periods prior to 
the Maryland Medical transaction and the Merger will not be restated since 
the acquisitions are not material to Corning's financial position or results 
of operations. The summary unaudited pro forma combined financial data set 
forth below is derived from, and should be read in conjunction with, the 
Corning Unaudited Pro Forma Combined Financial Information and the historical 
financial statements and notes thereto of Nichols included elsewhere in this 
Proxy Statement/Prospectus, and the historical financial statements of 
Corning and Damon and notes thereto incorporated by reference into this Proxy 
Statement/Prospectus. The unaudited pro forma combined financial data are 
presented for informational purposes only, and are not necessarily indicative 
of the results of operations or financial position which would have been 
achieved had the Corning Transactions been completed on the dates indicated 
or the results that may be attained in the future.

THE SPECIAL MEETING 

Special Meeting 

This Proxy Statement/Prospectus is being furnished to Nichols stockholders in 
connection with the solicitation by the Nichols Board of proxies for use at 
the Special Meeting to be held on Wednesday, August 31, 1994 at 9:30 a.m., 
local time, at 33608 Ortega Highway, San Juan Capistrano, California 92690, 
Building A. 

At the Special Meeting, holders of Class A Common Stock and Class B Common 
Stock will consider and vote upon a proposal to adopt the Merger Agreement. 
As a result of a voting agreement entered into between Corning and Dr. 
Nichols, adoption of the Merger Agreement by Nichols stockholders is assured. 
See "THE MERGER--Agreement of Dr. Nichols to Vote in Favor of the Merger." 
The Merger Agreement provides that, upon the terms and subject to the 
conditions thereof, Merger Sub will merge into Nichols, Nichols will become a 
wholly owned subsidiary of Corning and each share of Nichols Common Stock 
issued and outstanding immediately prior to the Merger (other than shares of 
Class B Common Stock as to which appraisal rights shall have been perfected) 
shall be converted into the right to receive that number (the Exchange Ratio) 
of Corning Common Shares equal to the quotient derived by dividing $13.00 by 
the average of the closing prices on the NYSE per Corning Common Share (as 
reported in the NYSE Composite Transactions) during the 10 consecutive 
trading days ending on the fifth trading day prior to the Special Meeting; 
provided, however, that in no event will the Exchange Ratio be greater than 
0.491. Each share of Nichols Preferred Stock (other than shares of Nichols 
Preferred Stock as to which appraisal rights shall have been perfected) shall 
be converted in the Merger into Corning Common Shares in the manner and 
amount provided for pursuant to the terms of the Nichols Preferred Stock. 
Each Corning Common Share issued in the Merger shall be accompanied by one 
Right unless the Rights shall not be outstanding as of the Effective Time. 
See "THE MERGER--Terms of the Merger." 

No fractional Corning Common Shares will be issued in the Merger. In lieu of 
any such fractional shares, each holder of Nichols Common Stock who otherwise 
would be entitled to receive a fractional Corning Common Share pursuant to 
the Merger Agreement will be paid an amount in cash, without interest, equal 
to such holder's proportionate interest in the net proceeds from the sale or 
sales in the open market by the Exchange Agent, on behalf of all of such 
holders, of the aggregate fractional Corning Common Shares, if any, that 
would have been issued in the Merger. As soon as practicable following the 
Effective Time, the Exchange Agent will determine the number of Excess 
Shares, if any, and the Exchange Agent, as agent for the former holders of 
Nichols Common Stock, will sell any such Excess Shares at the prevailing 
prices on the NYSE. The sale of any Excess Shares will be executed on the 
NYSE and will be executed in round lots to the extent practicable. See "THE 
MERGER--Terms of the Merger." 

Holders of Class A Common Stock and Class C Common Stock will not be entitled 
to appraisal rights as a result of the Merger. Holders of the Class B Common 
Stock and Nichols Preferred Stock have the right to demand appraisal of, and 
obtain payment for, the "fair value" of such shares by following the 
procedures prescribed in Section 262 of the DGCL, a copy of which is attached 
as Appendix D to this Proxy Statement/Prospectus, and which is summarized 
under "THE MERGER--Appraisal Rights for Unlisted Stock Only" in this Proxy 
Statement/Prospectus. Failure to take any of the steps required under Section 
262 on a timely basis could result in the loss of appraisal rights. 

The Nichols Board has unanimously approved the Merger Agreement, determined 
that the Merger is fair to and in the best interests of Nichols and its 
stockholders and recommends that Nichols stockholders vote FOR adoption of 
the Merger Agreement. The Executive Committee of the Corning Board, acting 
pursuant to authority delegated to it by the Corning Board, has approved the 
Merger Agreement and the issuance of Corning Common Shares in the Merger, and 
the Board of Directors of Merger Sub and Corning, as the sole stockholder of 
Merger Sub, have approved and adopted the Merger Agreement and the Merger. 
Approval of the Merger Agreement and the Merger by Corning's stockholders is 
not required. See "BACKGROUND AND REASONS FOR THE MERGER; RECOMMENDATION OF 
THE NICHOLS BOARD--Nichols' Reasons for the Merger; Recommendation of the 
Nichols Board" and "--Corning's Reasons for the Merger." 

Record Date; Shares Entitled to Vote; Vote Required 
The close of business on July 29, 1994 (the "Record Date") has been fixed as 
the record date for determining the holders of Nichols Common Stock who are 
entitled to notice of and to vote at the Special Meeting. As of the Record 
Date, there were         shares of Class A Common Stock and         shares of 
Class B Common Stock outstanding and entitled to vote. The holders of record 
on the Record Date of shares of Class A Common Stock are entitled to 
one-tenth of a vote per share of Class A Common Stock, and the holders of 
record on the Record Date of Class B Common Stock are entitled to one vote 
per share of Class B Common Stock, on each matter
<PAGE>
<PAGE>
 
submitted to a vote at the Special Meeting. Holders of Class A Common Stock 
and Class B Common Stock will vote together on the Merger Agreement as a 
single class. The presence in person or by proxy of the holders of shares 
representing a majority of the voting power of the Nichols Common Stock 
entitled to vote is necessary to constitute a quorum for the transaction of 
business at the Special Meeting. Under the Nichols Certificate of 
Incorporation, holders of shares of Class C Common Stock and Nichols 
Preferred Stock are not entitled to vote at the Special Meeting. Under the 
DGCL and the Nichols By-Laws, as amended (the "Nichols By-Laws"), the 
affirmative vote of holders of shares representing a majority of the 
outstanding voting power of the Nichols Common Stock present in person or 
represented by proxy at the Special Meeting is required for adoption of the 
Merger Agreement. 

Dr. Albert L. Nichols, who owns an aggregate of approximately 60% of the 
voting power of the Nichols Common Stock, has agreed to vote in favor of the 
Merger Agreement. Accordingly, adoption thereof by the Nichols stockholders 
is assured. See "THE MERGER--Agreement of Dr. Nichols to Vote in Favor of the 
Merger" and "SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT 
OF NICHOLS." 

Abstention from voting and broker nonvotes will have the practical effect of 
voting against adoption of the Merger Agreement since they represent one less 
vote for such adoption. However, since the adoption of the Merger Agreement 
by the Nichols stockholders is already assured, such abstentions and broker 
nonvotes will not affect the outcome of the vote. 

Proxies; Proxy Solicitation 
Shares of Class A Common Stock and Class B Common Stock represented by 
properly executed proxies received at or prior to the Special Meeting which 
have not been revoked will be voted at the Special Meeting in accordance with 
the instructions contained therein. Shares of Class A Common Stock and 
Class B Common Stock represented by properly executed proxies for which no 
instruction is given will be voted FOR adoption of the Merger Agreement. 
Nichols stockholders are requested to complete, sign, date and return 
promptly the enclosed proxy card in the postage-prepaid envelope provided for 
this purpose to ensure that their shares are voted. A stockholder may revoke 
a proxy by submitting at any time prior to the vote on the adoption of the 
Merger Agreement a later-dated proxy with respect to the same shares, by 
delivering written notice of revocation to the Secretary of Nichols at any 
time prior to such vote or by attending the Special Meeting and voting in 
person. Mere attendance at the Special Meeting will not in and of itself 
revoke a proxy. If a stockholder is not the registered direct holder of his 
or her shares, the stockholder must obtain appropriate documentation from the 
registered holder in order to be able to vote the shares in person. 

If the Special Meeting is postponed or adjourned for any reason, at any 
subsequent reconvening of the Special Meeting all proxies will be voted in 
the same manner as such proxies would have been voted at the original 
convening of the meeting (except for any proxies which have theretofore 
effectively been revoked or withdrawn), notwithstanding that they may have 
been effectively voted on the same or any other matter at a previous meeting. 

Nichols will bear the cost of soliciting proxies from its stockholders. In 
addition to solicitation by mail, directors, officers and employees of 
Nichols and Corning may solicit proxies by telephone, telegram or otherwise. 
Such directors, officers and employees of Nichols and Corning will not be 
additionally compensated for such solicitation but may be reimbursed for 
out-of-pocket expenses incurred in connection therewith. Brokerage firms, 
fiduciaries and other custodians who forward soliciting material to the 
beneficial owners of shares of Nichols Common Stock held of record by them 
will be reimbursed for their reasonable expenses incurred in forwarding such 
material. Nichols has retained D.F. King & Co., Inc. to aid in soliciting 
proxies from its stockholders. The fees of such firm are estimated to be 
$4,000 plus reimbursement of out-of-pocket expenses.

                    BACKGROUND AND REASONS FOR THE MERGER; 
                     RECOMMENDATION OF THE NICHOLS BOARD 

Background 
In September 1993, Nichols engaged Peter J. Solomon Securities Company 
Limited ("PJSC") as its financial advisor to, among other things, analyze and 
explore various corporate strategic alternatives for Nichols and made a 
public announcement of this fact. PJSC began to investigate a wide variety of 
strategic alternatives, and in connection therewith, commenced a review of 
Nichols' historical financial performance and its stock price performance, an 
analysis of its internal growth prospects and a review of options relating to 
the sale of various corporate assets. 

In November 1993, Nichols became concerned that its results of operations and 
the adverse financial effects of its announced intention to recognize a 
material restructuring charge in the fourth quarter of 1993 would result in 
its inability to remain in compliance with certain financial covenants 
contained in the loan agreements with its senior noteholders, concerning 
approximately $62 million of senior notes held by institutional lenders, and 
that waivers or amendments of those covenants might be unobtainable. The 
senior note agreements provide that if Nichols fails to comply with its loan 
covenants, the senior noteholders have the right to declare the entire unpaid 
balance of all senior notes immediately due and payable. If the senior notes 
were or are accelerated, Nichols would be unable to satisfy its obligations 
thereunder without the proceeds of a refinancing of the entire outstanding 
amount of the senior notes. 

In late November 1993, representatives of Nichols and PJSC met with the 
senior noteholders to review the probable senior notes covenant default as of 
December 31, 1993. Nichols both assured the senior noteholders that Nichols 
and PJSC were actively exploring alternatives to potentially refinance or 
prepay the senior notes and sought to obtain waivers and modify those senior 
note covenants probable of default. No such waivers or modifications have 
been received to date. PJSC also began to explore the option of refinancing 
the senior notes through a public or private offering, and held discussions 
with a number of major investment and commercial banks. 

After reviewing several refinancing proposals at its December 10, 1993 board 
meeting, in January 1994 Nichols began working on a public offering of $100 
million senior notes to be underwritten by CS First Boston. Nichols filed a 
Registration Statement on Form S-1 covering these notes with the Commission 
on April 20, 1994. The proceeds from the sale of these notes were to be used 
by Nichols to retire its outstanding senior notes and for certain other 
purposes designed to improve significantly its operating and financial 
flexibility. 

In the fourth quarter of 1993, PJSC also began to contact third parties that 
might be interested in investing in, a joint venture with, merging with or 
acquiring all or part of Nichols (a "Transaction"). PJSC and Nichols 
identified companies (the "Strategic Buyers") that possessed certain key 
attributes relating to a Transaction, including: (i) the financial capacity 
to complete a Transaction; (ii) the ability to analyze and pursue a 
Transaction within a reasonable amount of time and with a minimum amount of 
disruption to Nichols' operations; (iii) the proven ability to close a 
Transaction given appropriate information; and (iv) the greatest likelihood 
to pay the highest price for a Transaction. Several Strategic Buyers were 
identified by PJSC through this process, including Corning. PJSC advised the 
Nichols Board that, in PJSC's judgment, the Strategic Buyers represented the 
most likely potential buyers for Nichols that met the criteria set forth by 
the Nichols Board. PJSC contacted each Strategic Buyer, including Corning, to 
determine its interest in a potential Transaction. 

During the first five months of 1994, Nichols focused its efforts on its 
planned senior notes offering. Nichols and PJSC continued discussions with 
Strategic Buyers and other interested persons regarding a Transaction, but 
received no firm offers until the proposal received from Corning on May 25, 
1994, discussed below.
<PAGE>
<PAGE>
 
Although when contacted in November 1993 Corning had declined to pursue a 
potential Transaction, on May 9, 1994 Corning contacted PJSC expressing such 
an interest. On May 10, 1994, Corning entered into a confidentiality 
agreement with Nichols and thereafter PJSC delivered to Corning a 
Confidential Information Memorandum regarding Nichols that had been prepared 
by PJSC. 

On May 17, 1994, Corning contacted PJSC and expressed a preliminary 
indication of interest in acquiring Nichols at a value of $11.00 per share in 
Corning Common Shares, subject to additional due diligence. Corning indicated 
that the price might be higher than $11.00 per share depending upon the 
results of its due dilligence investigation. From May 19, 1994 through May 
24, 1994, Corning conducted operational, financial and legal due diligence on 
Nichols. 

On May 25, 1994, representatives of Corning and its financial advisor, Lazard 
Freres & Co., met with Dr. Nichols, Mr. George Bragg, Nichols' Chief 
Executive Officer, and representatives of PJSC to discuss the terms of a 
potential Transaction. At that meeting, representatives of Corning stated 
that they were prepared to recommend to the Corning Board that Corning enter 
into an agreement with Nichols pursuant to which each Nichols stockholder 
would receive up to $13.00 in value in Corning Common Shares for each share 
of Nichols Common Stock pursuant to a merger of a newly formed Corning 
subsidiary into Nichols, with Nichols being the surviving corporation. The 
Class A Common Stock and Class C Common Stock had closed that day at $4.938 
and $4.063, respectively, on the AMEX. The Corning representatives stated 
that Corning's offer to purchase Nichols was contingent upon the negotiation 
and execution of definitive agreements that would include, among other 
things, the agreement of Dr. Nichols to vote his shares in favor of the 
Merger, the requirement that the Merger be accounted for as a pooling of 
interests and that Nichols would be required to agree to a no solicitation 
provision in the Merger Agreement. The Corning representatives also requested 
Nichols to call a special meeting of the Nichols Board for May 31, 1994 to 
consider the Merger and advised the Nichols representatives that it would 
hold a meeting of the Executive Committee of the Corning Board to consider 
the Merger on June 1, 1994. The parties agreed to proceed to see if 
definitive agreements on all terms and conditions could be reached, and if 
the necessary board approvals for the transactions could be obtained, upon 
the terms and within the time frame outlined at that meeting. The Corning 
representatives made clear that Corning's proposal was contingent upon there 
not being disclosure to third parties of any possible Transaction until 
definitive agreements were executed. 

On May 26, 1994, Corning presented a draft Merger Agreement to Nichols. 
Pursuant to the Merger Agreement a wholly owned subsidiary of Corning would 
be merged with and into Nichols, with Nichols being the surviving 
corporation, and each share of Nichols Common Stock issued and outstanding 
would be converted into the right to receive that number of Corning Common 
Shares equal to the quotient derived by dividing $13.00 by the average of the 
per share closing price on the NYSE of Corning Common Shares during the 10 
consecutive trading days ending on the fifth trading day prior to the Special 
Meeting, provided that the Corning stock price was above a specified minimum 
level, below which a fixed exchange ratio (and thus a lower variable dollar 
value per share) would apply, and subject to certain other terms and 
conditions. 

From May 26, 1994 through May 31, 1994, Nichols and its advisors and Corning 
and its advisors proceeded to negotiate the terms of a final Merger 
Agreement. During these negotiations, Corning's representatives reiterated 
their position that Corning would be unwilling to proceed with the Merger 
unless the Merger Agreement contained a no solicitation provision and Dr. 
Nichols executed a voting agreement with Corning prior to or simultaneously 
with Corning's execution of the Merger Agreement. Corning's representatives 
stated that Corning's willingness to pay Nichols stockholders a substantial 
premium for their stock depended upon Corning's ability to assure itself that 
the Merger would be approved by the Nichols stockholders as a result of its 
voting agreement with Dr. Nichols and the no solicitation provision in the 
Merger Agreement. The structure of the Exchange Ratio was the subject of 
significant negotiation, with Corning ultimately agreeing to keep the $13.00 
value per share of Nichols Common Stock fixed above a specified minimum 
market price for Corning Common Shares, and that Nichols would have the right 
to terminate the Merger Agreement if, as of the time the Exchange Ratio is 
fixed, the value of Corning Common Shares to be received in the Merger per 
share of Nichols Common Stock were to be below $10.00. Corning's conditions 
to closing the Merger were also heavily negotiated. See "THE 
MERGER--Representations and Warranties" and "--Closing Conditions." 

The Nichols Board met on May 31, 1994 with its legal and financial advisors. 
It reviewed the current operating and financial condition of Nichols, the 
history of the Corning negotiations, the terms of the proposed Merger 
Agreement, including the various conditions to closing, the terms of the 
proposed voting agreement between Dr. Nichols and Corning and the status of 
discussions between PJSC and other potential buyers of Nichols. 

First Boston delivered the presentation described under "BACKGROUND AND 
REASONS FOR THE MERGER; RECOMMENDATIONS OF THE NICHOLS BOARD--Opinion of CS 
First Boston" regarding the
<PAGE>
<PAGE>
 
financial terms of the proposed Merger and responded to questions from the 
Nichols Board regarding, among other things, the outlook for Corning Common 
Shares, the liquidity of that stock and its views on the substantial premium 
over the current market price for Nichols Common Stock that was being offered 
by Corning. The First Boston representatives described the extent and results 
of CS First Boston's due diligence regarding Corning and its favorable 
evaluation of the prospects for Corning and the future performance of Corning 
Common Shares. The CS First Boston representatives also described in 
extensive detail how the Exchange Ratio formulation would operate at various 
prices for the Corning Common Shares. 

CS First Boston then rendered its opinion that the Merger is fair to the 
holders of each class of Nichols' stock from a financial point of view. 

PJSC then made its presentation to the Nichols Board regarding the history of 
its activities in exploring strategic alternatives for Nichols and the status 
of each alternative, including its discussions regarding a Transaction with 
all of the other Strategic Buyers and other potential acquirors. PJSC 
repeated its view that the Strategic Buyers constituted the most likely 
potential buyers for Nichols that met the criteria set forth by the Nichols 
Board. The PJSC representatives advised the Nichols Board that PJSC had not 
received a formal offer from any other Strategic Buyer or other party and no 
Strategic Buyer or other party had expressed an interest in acquiring Nichols 
at a price comparable to or greater than the price being offered by Corning. 

The Nichols Board next requested representatives from Nichols' independent 
auditors, Deloitte & Touche, to describe the requirements to account for the 
Merger as a pooling of interests in view of the fact that the closing of the 
Merger is conditioned upon the receipt by Corning of the opinion of its 
independent accountants that the Merger would be accounted for as a pooling 
of interests. Deloitte & Touche representatives reviewed the pooling 
requirements with the Nichols Board and analyzed these requirements in the 
context of specific situations that are present at Nichols. 

After presentations by counsel to Nichols regarding the duties of the Nichols 
Board and the terms of the proposed Merger Agreement, the Nichols Board 
proceeded to discuss the proposed Merger Agreement. Following this 
discussion, the Nichols Board unanimously approved the Merger Agreement. 

Nichols' Reasons for the Merger; Recommendation of the Nichols Board 
At the meeting held by the Nichols Board on May 31, 1994, the Nichols Board, 
by a unanimous vote of all directors, determined that the terms of the Merger 
are fair to and in the best interests of Nichols and its stockholders, 
approved the Merger Agreement and authorized and directed Mr. Bragg and Mr. 
Bellamy to execute the Merger Agreement on behalf of Nichols. 

Nichols executed the Merger Agreement on May 31, 1994 and Dr. Nichols 
executed the Dr. Nichols Letter Agreement contemporaneously therewith. After 
approval by the Executive Committee of the Corning Board, Corning executed 
the Merger Agreement on June 1, 1994 and press releases announcing the Merger 
Agreement and the transactions contemplated therein were issued. 

Accordingly, the Nichols Board, having unanimously approved the Merger 
Agreement and determined that the Merger is fair to and in the best interests 
of Nichols and its stockholders, recommends that the Nichols stockholders 
vote FOR adoption of the Merger Agreement. 

As described above under "Background," the decision of the Nichols Board to 
approve the Merger Agreement on May 31, 1994, followed almost nine months of 
exploring and analyzing strategic and financial alternatives available to 
Nichols. During this period, the Nichols Board met numerous times, at which 
meetings the Nichols Board reviewed in detail Nichols' business, results of 
operations and prospects, including possible Transactions with Strategic 
Buyers. Also during this period, PJSC presented to the Nichols Board periodic 
updates on the status of its exploration and analysis of various strategic 
and financial alternatives available to Nichols, including the contemplated 
offering of the Nichols high-yield senior notes. 

In making its recommendation to Nichols' stockholders with respect to the 
Merger, the Nichols Board considered a number of factors. These factors 
included, without assigning relative weights to, the following: 

  (i) the investigation and review by the Nichols Board of the Merger; 

  (ii) the knowledge and review of the business, assets and prospects of 
Nichols; 

  (iii) the information provided to the Nichols Board by the officers of 
Nichols and PJSC with respect to the financial and other aspects of the 
Merger, including the relationship thereof to other possible Transactions and 
the prospects of Nichols if the Merger were not to be effected;
<PAGE>
<PAGE>
 
(iv) the presentation of CS First Boston delivered to the Nichols Board at 
its meeting on May 31, 1994, including CS First Boston's written opinion, 
dated June 1, 1994, that, as of such date, the consideration to be received 
by the Nichols stockholders in connection with the proposed Merger is fair to 
such stockholders from a financial point of view; 

  (v) the review of the material terms and conditions of the Merger as 
reflected in the Merger Agreement, including the amount and form of 
consideration, the proposed price protection range and the fact that each 
holder of Nichols Common Stock will receive for their shares the same 
consideration, which the Nichols Board believed represented the most 
favorable transaction possible with Corning for the Nichols stockholders; 

  (vi) the historical and prospective business of Nichols, including, among 
other things, the current financial condition and future prospects of Nichols 
and the current financial condition and future prospects of Corning; 

  (vii) the conditions precedent to the consummation of the Merger, including 
regulatory approval and receipt of certain assurances that the Merger will be 
accounted for as a pooling of interests, and the estimated length of time to 
consummate the Merger; 

  (viii) alternatives to the Merger, including a public debt offering, and 
the risks associated with such alternatives, including the financial 
requirements to service any such debt, as well as the risks inherent in 
continuing as an independent public company in an industry that is both 
changing rapidly and consolidating as opposed to the strengths of a 
combination between Corning and Nichols; 

  (ix) recognizing that the execution of the Dr. Nichols Letter Agreement 
would assure the approval of the stockholders and would therefore preclude 
competing bidders, the absence of any other firm proposals by potential 
acquirors despite PJSC's efforts to solicit potential Transactions and the 
advice of PJSC that the Strategic Buyers represented the most likely 
potential buyers for Nichols that met the criteria set by the Nichols Board; 

  (x) the structure of the Merger, which would permit holders of Nichols 
Common Stock to exchange all their shares of Nichols Common Stock on a 
tax-free basis; and 

  (xi) such other matters as the Nichols Board deemed appropriate or 
necessary in considering the Merger. 

Determination of the Nichols Board as to Voting Rights 
The holders of Nichols Common Stock will not be entitled to approve or 
disapprove the Merger by separate class votes. The Nichols Certificate of 
Incorporation provides that under certain circumstances a merger or 
consolidation must be approved by separate class votes of one or more of the 
classes of its Common Stock. If, however, (i) the holders of Nichols Common 
Stock are to each receive identical consideration on a per share outstanding 
basis, and therefore the "Equal Consideration Requirement" provided for in 
the Nichols Certificate of Incorporation would be met and (ii) the merger or 
consolidation is not with a Related Person (as defined in the Nichols 
Certificate of Incorporation) and therefore the "Fair Consideration 
Requirement" provided for in the Nichols Certificate of Incorporation would 
not apply, the holders of Class A Common Stock and Class B Common Stock would 
vote together as a single class, and the holders of Class C Common Stock 
would not be entitled to vote on the merger or consolidation. The Nichols 
Board has determined, with the advice of counsel, that the Equal 
Consideration Requirement will be met with respect to the Merger since the 
holders of Nichols Common Stock will each receive identical consideration on 
a per share outstanding basis. Furthermore, the Nichols Board has determined 
that the Merger is not with a Related Person and, accordingly, the Fair 
Consideration Requirement does not apply. See "DESCRIPTION OF NICHOLS CAPITAL 
STOCK--Voting on Mergers, Consolidations and Other Business Combinations" and 
"COMPARATIVE RIGHTS OF NICHOLS STOCKHOLDERS AND CORNING STOCKHOLDERS--Mergers 
and Consolidations of Nichols Which are Not Related Person Business 
Combinations." 

Opinion of CS First Boston 
CS First Boston delivered to the Nichols Board its written opinion that, as 
of June 1, 1994, the consideration to be received by the Nichols stockholders 
in connection with the Merger is fair to each class of such stockholders from 
a financial point of view. Such opinion confirmed the oral opinion given by 
CS First Boston to the Nichols Board on May 31, 1994. 

The full text of the opinion of CS First Boston dated June 1, 1994, which 
sets forth assumptions made, matters considered and limits on the review 
undertaken, is attached as Appendix C to this Proxy Statement/Prospectus. 
Nichols stockholders are urged to read such opinion in its entirety. CS First 
Boston's opinion is directed only to the fairness of the consideration to be 
received by the Nichols stockholders and does not constitute a recommen

dation to any Nichols stockholder as to how such stockholder should vote. The 
summary of the opinion of CS First Boston set forth in this Proxy 
Statement/Prospectus is qualified in its entirety by reference to the full 
text of such opinion. 

In arriving at its opinion, CS First Boston (i) reviewed the Merger 
Agreement, (ii) reviewed certain publicly available business and financial 
information relating to Nichols and Corning; (iii) reviewed certain other 
information, including financial forecasts, provided to CS First Boston by 
Nichols and Corning; (iv) discussed the business and prospects of Nichols and 
Corning with Nichols and Corning management, respectively; (v) considered 
certain financial and stock market data of Nichols and Corning and compared 
that data for Nichols with similar data for other publicly held companies in 
businesses similar to that of Nichols; (vi) considered the financial terms of 
certain other business combinations which have recently been effected; (vii) 
considered such other information, financial studies, analyses and 
investigations and financial, economic and market criteria which CS First 
Boston deemed relevant; and (viii) discussed with representatives of Nichols 
and PJSC information developed by PJSC regarding other potential 
opportunities for the sale of Nichols; however, CS First Boston was not 
involved in any discussions which representatives of Nichols or PJSC may have 
had with any third parties in this regard. 

In connection with its review, CS First Boston did not independently verify 
any of the foregoing information and relied on it being complete and accurate 
in all material respects. With respect to the financial forecasts, CS First 
Boston assumed that they had been reasonably prepared on bases reflecting the 
best currently available estimates and judgments of Nichols and Corning 
management as to the future financial performance of Nichols and Corning, 
respectively. In addition, CS First Boston did not independently evaluate or 
appraise the assets of Nichols or Corning, nor was it furnished with any such 
appraisals. 

In arriving at its opinion and making its presentation to the Nichols Board 
on May 31, 1994, CS First Boston performed a variety of financial analyses, 
including those summarized below. The summary set forth below includes 
summaries of all of the material financial analyses discussed by CS First 
Boston with the Nichols Board, but does not purport to be a complete 
description of the analyses performed by CS First Boston in arriving at its 
opinion. Arriving at a fairness opinion is a complex process that involves 
various determinations as to the most appropriate and relevant methods of 
financial analysis and the application of those methods to the particular 
circumstances and, therefore, such an opinion is not necessarily susceptible 
to partial analysis or summary description. CS First Boston believes that its 
analyses must be considered as a whole and that selecting portions of its 
analyses or only certain of the factors considered by it without considering 
all analyses and factors, could create an incomplete view of the evaluation 
process underlying its opinion. In performing its analyses, CS First Boston 
made numerous assumptions with respect to industry performance, general 
business, economic, market and financial conditions and other matters, many 
of which are beyond the control of CS First Boston, Nichols or Corning. Any 
estimates incorporated in the analyses performed by CS First Boston are not 
necessarily indicative of actual values or future results, which may be 
significantly more or less favorable than suggested by such analyses. 
Additionally, estimates of the value of businesses and securities neither 
purport to be appraisals nor necessarily reflect the prices at which 
businesses or securities actually may be sold. Accordingly, such analyses and 
estimates are inherently subject to substantial uncertainty. No public 
company utilized as a comparison is identical to Nichols, and none of the 
acquisition transactions utilized as comparisons is identical to the Merger. 
Accordingly, an analysis of publicly traded comparable companies and 
comparable acquisition transactions is not mathematical; rather it involves 
complex considerations and judgments concerning differences in financial and 
operating characteristics of the comparable companies and other factors that 
could affect the public trading value of the comparable companies or company 
to which they are being compared. 

The following is a summary of the analyses performed by CS First Boston and 
presented to the Nichols Board in connection with its fairness opinion: 

Premium Paid. CS First Boston considered the premium paid for Nichols Common 
Stock based on average prices of publicly traded Nichols Common Stock over 
the following periods: 
<TABLE>
<CAPTION>
  Period Prior 
to Announcement   Weighted Average Price     Weighted Average Premium 
<S>                         <C>                        <C>
    One Day                 $4.40                      195.3% 
    One Week                 4.42                       194.4 
   One Month                 4.43                       200.4 
</TABLE>
This analysis illustrated that the Merger price per common share provides a 
significant premium to Nichols Common Stock over each period. 

Discounted Cash Flow Analysis. Using a discounted cash flow analysis, CS 
First Boston estimated the present value of the future cash flows that 
Nichols could produce over a ten-year period from 1994 through 2003, under
<PAGE>
<PAGE>
 
various assumptions, if Nichols were to perform on a stand-alone basis in 
accordance with forecasts prepared by Nichols management. CS First Boston 
determined certain equity market value reference ranges for Nichols based 
upon the sum of (i) (A) the aggregate discounted present value (using various 
discount rates ranging from 11% to 14%) of the ten-year unleveraged free cash 
flows of Nichols (as projected by Nichols), plus (B) the discounted present 
value (using various discount rates ranging from 11% to 14%) of (a) the 
projected earnings for 2003 (as projected by Nichols) before interest, taxes, 
depreciation and amortization ("EBITDA") multiplied by (b) numbers 
representing various terminal or exit multiples (ranging from 7x to 10x), 
plus (ii) certain corporate adjustments made by subtracting debt and adding 
cash, cash equivalents, marketable securities and estimated cash proceeds 
from the exercise of certain stock options. This analysis resulted in an 
equity value reference range per share of Nichols Common Stock from $7.95 to 
$13.75. 

Comparable Company Analysis.  CS First Boston also reviewed and compared the 
financial and market performance of the following group of six publicly 
traded clinical laboratory companies with that of Nichols: Allied Clinical 
Laboratories, Inc., Dianon Systems, Inc., National Health Laboratories 
Incorporated, Physicians Clinical Laboratory, Inc., Unilab Corporation and 
Universal Standard Medical Laboratories, Inc. CS First Boston selected these 
companies on the basis of various factors, including primarily each company's 
concentration in the clinical laboratory industry. CS First Boston examined 
certain publicly available financial data for these companies, including the 
multiple of adjusted market value (defined as equity market value adjusted by 
adding total debt and subtracting cash, marketable securities and estimated 
cash proceeds from the exercise of certain stock options) to total revenues, 
EBITDA, earnings before interest and taxes ("EBIT"), and the multiple of 
equity market value to net income and tangible book value. CS First Boston 
then applied certain of these multiples to publicly available estimates of 
Nichols' revenues, EBITDA, EBIT and tangible book value for the period of 
twelve months prior to March 31, 1994; and net income for the forecasted 
periods of fiscal year end 1994 and 1995. This analysis resulted in an equity 
value reference range per share of Nichols Common Stock from $4.65 to $9.95. 

Comparable Acquisition Analysis. CS First Boston also reviewed the 
consideration paid or proposed to be paid in other recent acquisitions of 
clinical laboratory companies. While CS First Boston reviewed comparable 
clinical laboratory company acquisitions for the past seven years, CS First 
Boston focused on the following target/acquiror transactions: Allied Clinical 
Laboratories, Inc./National Health Laboratories Incorporated (announced May 
1994, pending), and Damon Corporation/Corning Inc. (announced June 1993; 
completed), as these more recent transactions of public companies better 
reflect current business and financial conditions in the clinical laboratory 
industry. The analysis considered the multiple of adjusted market value to 
revenues, EBITDA and EBIT and the multiple of equity market value to net 
income and tangible book value for the period of twelve months prior to March 
31, 1994. This analysis resulted in an equity value reference range per share 
of Nichols Common Stock from $8.45 to $14.50. 

CS First Boston is an internationally recognized investment banking firm 
engaged in the evaluation of businesses and their securities in connection 
with mergers and acquisitions and for other purposes. CS First Boston was 
selected as financial advisor to Nichols based on such expertise. 

In the ordinary course of its business, CS First Boston may trade the debt 
and equity securities of Nichols for CS First Boston's own account and for 
the accounts of its customers and, accordingly, may at any time hold a long 
or short position in such securities. Further, John M. Hennessy, Chairman of 
the Executive Board and Chief Executive Officer of CS First Boston, is a 
member of Corning's Board. 

Fee paid to CS First Boston. Nichols has agreed to pay CS First Boston a fee 
of $750,000 in consideration of CS First Boston's services, $250,000 of which 
was payable at the time of delivery of its fairness opinion to Nichols, and 
$500,000 of which will be payable upon consummation of the Merger. Nichols 
has also agreed to reimburse CS First Boston for its out-of-pocket expenses, 
including reasonable fees and disbursements of counsel. Nichols has agreed to 
indemnify CS First Boston and its affiliates, their respective directors, 
officers, partners, agents and employees and each person, if any, controlling 
CS First Boston or any of its affiliates against certain liabilities, 
including certain liabilities under the federal securities laws, relating to 
or arising out of its engagement. 

Fee paid to PJSC. If the Merger is consummated, Nichols has agreed to pay 
PJSC a fee equal to 1-1/2% of the Aggregate Consideration in the Merger, less 
$500,000. For the purpose hereof, the term Aggregate Consideration means the 
total amount of cash and the fair market value (on the date of payment) of 
all other property paid or payable, directly or indirectly, to or by Nichols 
or to Nichols' security holders in connection with the Merger (including, 
without limitation, amounts paid by Nichols or any other party to holders of 
any warrants, stock purchase rights, convertible securities, Nichols 
Preferred Stock or similar rights of Nichols and to holders of any options or 
stock appreciation rights issued by Nichols whether or not vested). Aggregate 
Consideration shall also include
<PAGE>
<PAGE>
 
the value of any short-term debt and long-term liabilities (including the 
principal amount of indebtedness for borrowed money) repaid or retired in 
connection with or in anticipation of the Merger or existing on the balance 
sheet of Nichols at the Effective Time. 

Corning's Reasons for the Merger 
The Corning Board believes that the Merger is in the best interests of 
Corning and its stockholders because it strategically positions and 
differentiates MetPath, Inc. ("MetPath"), the clinical laboratory testing 
unit of Corning, for growth in the hospital reference testing market, while 
expanding MetPath's presence in both complementary and new geographies. 
MetPath will benefit through geographic synergy in the south central region 
and midwest, and will add several new territories in the far west. The 
hospital market, with health-care reform, will present a significant 
opportunity for a medically and scientifically driven, low-cost laboratory. 
Nichols enjoys an outstanding reputation for its medical and scientific 
expertise, as well as a strong position in the hospital reference testing 
market. 

                                  THE MERGER 

The description of the Merger Agreement and the Merger set forth below does 
not purport to be complete and is qualified in its entirety by reference to 
the Merger Agreement and to the Dr. Nichols Letter Agreement, copies of which 
are attached as Appendix A and Appendix B, respectively, to this Proxy 
Statement/Prospectus and incorporated by reference herein. 

Terms of the Merger 
The Merger. Subject to the terms and conditions of the Merger Agreement, 
Merger Sub will merge with and into Nichols at the Effective Time. The 
separate corporate existence of Merger Sub will then cease, and the internal 
corporate affairs of Nichols (the "Surviving Corporation") will continue to 
be governed by the laws of the State of Delaware. 

Effective Time. Subject to the provisions of the Merger Agreement, as soon as 
practicable on or after the Closing Date, the parties shall file a 
certificate of merger or other appropriate documents (in any such case, the 
"Certificate of Merger") executed in accordance with the relevant provisions 
of the DGCL and shall make all other filings or recordings required under the 
DGCL. The Merger shall become effective at such time as the Certificate of 
Merger is duly filed with the Delaware Secretary of State, or at such other 
time as Merger Sub and Nichols shall agree should be specified in the 
Certificate of Merger (the date and time of such filing, or such later date 
or time as may be set forth therein, being the Effective Time). 

Certificate of Incorporation and By-Laws. The Merger Agreement provides that 
the certificate of incorporation of Merger Sub as in effect immediately prior 
to the Effective Time will become the certificate of incorporation of the 
Surviving Corporation (except that such certificate of incorporation shall be 
amended at the Effective Time to provide that the name of the Surviving 
Corporation shall be "Nichols Institute"). The by-laws of Merger Sub in 
effect at the Effective Time will become the by-laws of the Surviving 
Corporation. 

Directors. The directors of Merger Sub at the Effective Time shall continue 
as the directors of the Surviving Corporation, until the earlier of their 
resignation or removal or until their respective successors are duly elected 
and qualified, as the case may be. 

Officers. The officers of Nichols immediately prior to the Effective Time 
shall become the officers of the Surviving Corporation, until the earlier of 
their resignation or removal or until their respective successors are duly 
elected and qualified, as the case may be. 

Effect on Capital Stock 
Conversion of Nichols Common Stock in the Merger. At the Effective Time, by 
virtue of the Merger and without any action on the part of Corning, Merger 
Sub, Nichols, or the holders of any shares of Nichols Common Stock or any 
shares of capital stock of Merger Sub: (i) each share of the capital stock of 
Merger Sub outstanding as of the Effective Time shall be converted into and 
exchanged for one fully paid and nonassessable share of common stock of the 
Surviving Corporation; and (ii) each share of Nichols Common Stock that is 
owned by Nichols or by any subsidiary of Nichols and each share of Nichols 
Common Stock that is owned by Corning, Merger Sub or any other subsidiary of 
Corning immediately prior to the Effective Time shall automatically be 
cancelled and retired without any conversion thereof and no consideration 
shall be delivered with respect thereto. 

Each share of Nichols Common Stock issued and outstanding as of the Effective 
Time (other than shares to be cancelled in accordance with (ii) above and 
shares of Class B Common Stock as to which appraisal rights shall have been 
perfected) shall be converted, subject to the terms explained in "No 
Fractional Shares", into the right to receive that number (the Exchange 
Ratio) of Corning Common Shares, rounded to the nearest thousandth, or
<PAGE>
<PAGE>
 
if there shall not be a nearest thousandth, to the next lower thousandth, 
equal to the quotient derived by dividing $13.00 by the average of the per 
share closing prices on the NYSE of Corning Common Shares (as reported in the 
NYSE Composite Transactions) during the 10 consecutive trading days ending on 
the fifth trading day prior to the Special Meeting; provided, however, that 
in no event will the Exchange Ratio be greater than 0.491 and if the Exchange 
Ratio, as calculated, would be above that limit, then it shall be fixed at 
such maximum limit; provided, further, that in the event the Exchange Ratio, 
as calculated (without reference to the foregoing proviso), would equal or be 
greater than 0.638, then Nichols may, but shall not be obligated to, 
terminate the Merger Agreement. Each share of Nichols' Preferred Stock (other 
than shares of Nichols Preferred Stock as to which appraisal rights shall 
have been perfected) shall be converted in the Merger into Corning Common 
Shares in the manner and amount provided for pursuant to the terms of the 
Nichols Preferred Stock. See "DESCRIPTION OF NICHOLS STOCK--Preferred Stock." 
If, prior to the Effective Time, Corning should split or combine the Corning 
Common Shares, or pay a stock dividend or other stock distribution in Corning 
Common Shares, then the Exchange Ratio (including the maximum limit thereof) 
will be appropriately adjusted to reflect such split, combination, dividend 
or other distribution. Each Corning Common Share issued pursuant to this 
conversion shall be accompanied by one Right, unless the Rights shall not be 
outstanding as of the Effective Time. 

As of the Effective Time, all such shares of Nichols Common Stock and Nichols 
Preferred Stock shall no longer be outstanding and shall automatically be 
cancelled and retired and shall cease to exist, and each certificate 
previously representing any such shares (including any certificate 
theretofore representing Nichols Preferred Stock) shall thereafter represent 
the right to receive a certificate representing the Corning Common Shares 
into which such Nichols Common Stock was converted in the Merger. The holders 
of such certificates previously evidencing such shares of Nichols Common 
Stock and Nichols Preferred Stock outstanding immediately prior to the 
Effective Time shall cease to have any rights with respect to such shares of 
Nichols Common Stock or Nichols Preferred Stock as of the Effective Time 
except as otherwise provided in the Merger Agreement or by law. Such 
certificates previously representing shares of Nichols Common Stock and 
Nichols Preferred Stock shall be exchanged for certificates representing 
whole Corning Common Shares issued in consideration therefor upon the 
surrender of such certificates in accordance with the provisions of "Exchange 
of Certificates," without interest. No fractional Corning Common Share shall 
be issued, and in lieu thereof a cash payment shall be made. See "No 
Fractional Shares." 

Exchange of Certificates. Prior to the Effective Time, Corning shall enter 
into an agreement with Harris Trust and Savings Bank, as Exchange Agent, and 
as contemplated by such agreement, Corning shall deposit, or shall cause to 
be deposited, with the Exchange Agent as of the Effective Time (or otherwise 
when requested by the Exchange Agent from time to time in order to effect any 
exchange pursuant to this Section) for the benefit of the holders of shares 
of Nichols Common Stock, for exchange through the Exchange Agent, 
certificates representing the Corning Common Shares issuable pursuant to the 
terms of the Merger Agreement described in "Effect on Capital Stock" in 
exchange for outstanding shares of Nichols Common Stock (such certificates 
representing Corning Common Shares, together with any dividends or 
distributions with respect thereto, being collectively referred to as the 
"Exchange Fund"). The Exchange Agent shall, pursuant to irrevocable 
instructions, deliver the Corning Common Shares contemplated to be issued 
pursuant to the terms of the Merger Agreement described in "Effect on Capital 
Stock" out of the Exchange Fund. Except as contemplated by the terms of the 
Merger Agreement described in "No Fractional Shares," the Exchange Fund shall 
not be used for any other purpose. 

As soon as reasonably practicable after the Effective Time, Corning shall 
instruct the Exchange Agent to mail to each holder of record of a certificate 
or certificates which immediately prior to the Effective Time represented 
outstanding shares of Nichols Common Stock or Nichols Preferred Stock (the 
"Certificates"), (i) a letter of transmittal (which shall specify that 
delivery shall be effected, and risk of loss and title to the Certificates 
shall pass, only upon proper delivery of the Certificates to the Exchange 
Agent and which shall be in a customary form) and (ii) instructions for use 
in effecting the surrender of the Certificates in exchange for certificates 
representing Corning Common Shares. Until surrendered as contemplated by the 
terms of the Merger Agreement described in this Section, each Certificate 
shall be deemed at any time after the Effective Time to represent only the 
right to receive upon such surrender the certificate evidencing whole Corning 
Common Shares (and the accompanying Rights), cash in lieu of any fractional 
Corning Common Shares to which such holder is entitled and any dividends or 
other distributions to which such holder is entitled pursuant to the terms of 
the Merger Agreement. No interest will be paid or will accrue on any cash 
payable pursuant to the provisions of the Merger Agreement concerning 
unexchanged shares and fractional shares. 

No dividends or other distributions declared or made after the Effective Time 
with respect to Corning Common Shares with a record date after the Effective 
Time shall be paid to the holder of any unsurrendered Certificate with 
respect to the Corning Common Shares represented thereby, and no cash payment 
in lieu of fractional shares shall be paid to any such holder, in each case 
until the surrender of such Certificate in accordance with the terms of the 
Merger Agreement described in this Section.
<PAGE>
<PAGE>
 
All Corning Common Shares issued upon the surrender for exchange of 
Certificates in accordance with the terms of the Merger Agreement shall be 
deemed to have been issued (and paid) in full satisfaction of all rights 
pertaining to the shares of Nichols Common Stock and Nichols Preferred Stock 
theretofore represented by such Certificates, subject, however, to the 
Surviving Corporation's obligation to pay any dividends or make any other 
distributions with a record date prior to the Effective Time which may have 
been declared or made by Nichols on such shares of Nichols Common Stock or 
Nichols Preferred Stock in accordance with the terms of the Merger Agreement 
or prior to the date of the Merger Agreement and which remain unpaid at the 
Effective Time and have not been paid prior to surrender. At the Effective 
Time, the stock transfer books of Nichols shall be closed, and there shall be 
no further registration of transfers of shares of Nichols Common Stock or 
Nichols Preferred Stock thereafter on the records of Nichols. 

No Fractional Shares. No certificates or scrip representing fractional 
Corning Common Shares shall be issued upon the surrender for exchange of 
Certificates, and such fractional share interests will not entitle the owner 
thereof to vote or to any rights of a stockholder of Corning. Following the 
Effective Time, Corning shall instruct the Exchange Agent to determine the 
excess of (x) the number of full Corning Common Shares delivered to the 
Exchange Agent by Corning over (y) the aggregate number of Corning Common 
Shares to be distributed to holders of Certificates (such excess being the 
Excess Shares). As soon after the Effective Time as practicable, the Exchange 
Agent, as agent for such holders of Certificates, shall sell the Excess 
Shares at the then prevailing prices on the NYSE. Until the net proceeds of 
such sale or sales have been distributed to such holders of Certificates, the 
Exchange Agent will hold such proceeds in trust for such holders of 
Certificates (the "Trust"). The Exchange Agent shall determine the portion of 
the Trust to which each holder of one or more Certificates shall be entitled, 
if any, and shall promptly pay such amounts to such holders of Certificates 
subject to and in accordance with the terms of the Merger Agreement. 

Representations and Warranties 
The Merger Agreement contains various representations and warranties of the 
parties thereto. The Merger Agreement includes representations and warranties 
by Nichols as to (i) the corporate organization, standing and power of 
Nichols and its subsidiaries, (ii) approvals by the Nichols Board and 
fairness opinions received by Nichols, (iii) its capitalization, (iv) the 
authorization of the Merger Agreement, (v) pending or threatened litigation, 
(vi) the Merger Agreement's noncontravention of any agreement, law or charter 
or by-law provision and the absence of the need (except as specified) for

Nichols employee plans, and certain other matters relating to the Employee

accuracy of Nichols' financial statements and filings with the Commission,

finders employed by Nichols, (xv) the accuracy of information to be supplied 
by Nichols for inclusion in this Proxy Statement/Prospectus and in the 
Registration Statement, and (xvi) certain tax matters. 

For purposes of the Merger Agreement "material adverse change" or "material 
adverse effect" means, when used in connection with Nichols or Corning, any 
change or effect (or any development that, insofar as can reasonably be 
foreseen, is likely to result in any change or effect) that is materially 
adverse to the business, financial condition or results of operations of such 
party and its subsidiaries taken as a whole; provided, however, that the 
existence or occurrence of the following events and circumstances shall not 
individually constitute "material adverse change" or "material adverse 
effect": (i) any change in laws and rules regulating the performance, 
marketing and/or billing of laboratory tests, or limiting the reimbursements 
or payments therefor; (ii) changes relating to the economy in general or to 
Nichols' industry in general and not specifically relating to Nichols; (iii) 
changes relating to the cancellation or termination by customers of Nichols 
of their relationships with Nichols or the voluntary termination by existing 
general managers, or sales representatives from and after the date of the 
public announcement of this agreement unless such cancellations or 
terminations are attributable in large respect to factors other than the 
transactions contemplated by the Merger Agreement; (iv) the assessment from 
the Internal Revenue Service relating to the amortization of certain 
intangible items or any future assessment based on the same factual 
circumstances for subsequent years, unless such change or effect results from 
a state of facts known or which ought to be known to the officers of Nichols 
on the date of the Merger Agreement and not disclosed to Corning prior to the 
execution thereof; or (v) the subpoena received by Nichols in August 1993 
from the Office of Inspector General and the United States Attorney's Office 
for the Southern District of California relating to Medicare billing 
practices, or any developments, investigations, or charges arising therefrom 
or payments or settlements relating thereto, unless (x) such matters would 
have a reasonable probability of resulting in a material penalty being 
imposed against Nichols or
<PAGE>
<PAGE>
 
in a referral to a grand jury or similar authority being made with respect to 
Nichols or in exclusion of Nichols from participation in Medicare, Medicaid 
or any other federal or state health care program or (y) such change or 
effect results from a state of facts known or which ought to be known to the 
officers of Nichols on the date of the Merger Agreement and not disclosed to 
Corning prior to the execution thereof. 

The Merger Agreement also includes representations and warranties by Corning 
and Merger Sub as to: (i) the corporate organization, standing and power of 
Corning and its subsidiaries; (ii) the authorization of the Merger Agreement; 
(iii) Corning's capitalization; (iv) the authorization of the Corning Common 
Shares to be issued pursuant to the Merger Agreement; (v) pending or

Statement/Prospectus and in the Registration Statement; (xiii) the ownership 
of shares of Nichols Common Stock by Corning; and (xiv) certain tax matters. 

Certain Covenants 
Conduct of Business by Nichols. The Merger Agreement provides that between 
the date of the Merger Agreement and the Effective Time, Nichols shall, and 
shall cause its subsidiaries to, carry on their respective businesses in the 
ordinary course and use all reasonable efforts to preserve intact their 
current business organizations, keep available the services of their current 
officers and employees and preserve their relationships with customers, 
suppliers and others having business dealings with them. The Merger Agreement 
further provides, without limiting the generality of the foregoing, that

effect of any of the foregoing except for the incurrence of indebtedness to 
finance Nichols' working capital needs (which may include mandatory payments 
under the Senior Notes) which, in the aggregate, does not exceed $15,000,000 
provided that the terms of any such indebtedness (including any prepayment 
penalty) shall be subject to the approval of Corning (which approval shall 
not be unreasonably withheld), or (B) make any loans, advances or capital

1990, except as may be required by applicable law; (ix) pay, discharge or 
satisfy any claims, liabilities or obligations (absolute, accrued, asserted

practice or in accordance with their terms, of liabilities reflected or 
reserved against in, or contemplated by, the most recent consolidated 
financial statements (or the notes thereto) of Nichols included in the

business consistent with past practice; (x) (A) increase the rate or terms of

sharing, bonus, incentive, deferred compensation, stock purchase, stock 
option, stock appreciation right, group insurance, severance pay, 
continuation pay, termination pay, retirement or other employee benefit plan,

or benefit arrangement, (D) enter into any employment agreement with or for 
the benefit of any person or (E) increase the rate of compensation under or 
otherwise (except as expressly contemplated by the Merger Agreement) change 
the terms of any existing employment agreement; provided, however, that 
nothing in this clause (x) shall preclude payments under the terms of the 
existing incentive compensation plans of Nichols in accordance with past 
practice; (xi) except in the ordinary course of business consistent with past

foregoing actions. 

Conduct of Business by Corning. During the period from the date of the Merger 
Agreement to the Effective Time, Corning has agreed that it shall, and shall 
cause its subsidiaries to, carry on their respective businesses in the 
ordinary course and use all reasonable efforts to preserve their 
relationships with customers, suppliers and others having business dealings 
with them; provided that the foregoing shall not prevent Corning or any of 
its subsidiaries from discontinuing or disposing of any part of its assets or 
business or from acquiring any assets or businesses or from entering into any 
financing transactions if such action is, in the judgment of Corning, 
desirable in the conduct of the business of Corning and its subsidiaries. 
Without limiting the generality of the foregoing, during the period from the 
date of the Merger Agreement to the Effective Time, except as (i) 
contemplated by the Merger Agreement or (ii) as set forth in a writing 
delivered to Nichols prior to the execution hereof, Corning has agreed that 
it shall not, and shall not permit any of its subsidiaries to: 

  (i) (A) declare, set aside or pay (whether in cash or property, but 
excluding stock dividends) any dividends on, or make any other distributions 
in respect of, any capital stock other than dividends and distributions by 
any direct or indirect wholly owned subsidiary of Corning to its parent and 
except for regular quarterly cash dividends (in an amount determined in a 
manner consistent with Corning's past practice) declared by the Corning Board 
with customary record and payment dates, (B) split, combine or reclassify any 
of its capital stock or issue or authorize the issuance of any other 
securities in respect of, in lieu of or in substitution for shares of 
Corning's capital stock or (C) purchase, redeem or otherwise acquire any 
Corning Common Shares; 

  (ii) amend its certificate of incorporation, by-laws or other comparable 
charter or organizational documents in a manner which would reasonably be 
expected to be materially adverse to the stockholders of Nichols; 

  (iii) amend the Rights or the agreements under which the Rights are issued 
in any manner adverse to the stockholders of Nichols; 

  (iv) change its fiscal year; or 

  (v) authorize, or commit or agree to take any of, the foregoing actions. 

No Solicitation. (a) In light of the consideration given by the Nichols Board 
prior to the execution of the Merger Agreement to, among other things, the 
transactions contemplated thereby and by the requirement of Corning that the 
Dr. Nichols Letter Agreement be executed concurrently with the execution of 
the Merger Agreement as a condition of Corning's entering into the Merger 
Agreement, and to various alternatives to the transactions contemplated by 
the Merger Agreement, and in light of the fairness opinion issued to Nichols 
by First Boston as provided for in the Merger Agreement and the information 
provided to Nichols by its financial advisor, PJSC regarding potential 
alternative opportunities for the sale of Nichols, Nichols agreed that it 
shall not, nor shall it permit any
<PAGE>
<PAGE>
 
of its subsidiaries to, nor shall it authorize or permit any officer, 
director or employee of, or any investment banker, attorney or other advisor 
or representative of, Nichols or any of its subsidiaries to, solicit or 
initiate, or encourage the submission of, any Takeover Proposal, or 
participate in any discussions or negotiations regarding, or furnish to any 
person any information with respect to, or take any other action to 
facilitate any inquiries or the making of any proposal that constitutes, or 
may reasonably be expected to lead to, any Takeover Proposal. For purposes of 
the Merger Agreement, "Takeover Proposal" means any proposal (whether or not 
in writing and whether or not delivered to Nichols' stockholders generally) 
for a merger or other business combination involving Nichols or any of its 
material subsidiaries or any proposal or offer to acquire in any manner, 
directly or indirectly, an equity interest in, any voting securities of, or a 
substantial portion of the assets of Nichols or any of its material 
subsidiaries, other than the transactions contemplated by the Merger 
Agreement. Nothing contained in the Merger Agreement prohibits Nichols from 
taking and disclosing to its stockholders a position contemplated by Rule 
14e-2(a) under the Exchange Act with respect to a Takeover Proposal by means 
of a tender offer. 

(b) Nichols has agreed to promptly advise Corning orally and in writing of 
any request for information or of any Takeover Proposal, or any inquiry with 
respect to or which could lead to any Takeover Proposal, the material terms 
and conditions of such request, Takeover Proposal or inquiry, and the 
identity of the person making any such Takeover Proposal or inquiry. Nichols 
has agreed to keep Corning informed of the status and details of any such 
request, Takeover Proposal or inquiry. 

Repayment of Senior Notes. Pursuant to the Merger Agreement, at the Closing, 
Corning shall repay, or cause the Surviving Corporation to repay, in full the 
outstanding principal amount under Nichols' 10.12% senior notes due 2001, 
10.75% senior notes due 1998 and 10.43% senior notes due 1999 (collectively, 
the "Senior Notes") together with interest accrued but unpaid thereon, but 
without any prepayment penalty, to the holders of the Senior Notes. The 
Merger Agreement also provides that prior to the Closing Date, Nichols shall 
secure the waiver by the requisite majority of the holders of the Senior 
Notes of any penalty due under the terms of the Senior Notes upon the 
prepayment thereof by Corning or the Surviving Corporation. 

Restrictions on Corning's Business. The Merger Agreement provides that prior 
to the Closing Date, Nichols shall take all actions necessary and appropriate 
to eliminate any restrictions on the business and operations of Corning that 
are material to the business or results of operations of Corning or CLSI 
which may arise upon the consummation of the Merger as a result of any 
agreement between Nichols and any other person. 

Benefit Plans. The Merger Agreement states that Corning currently intends to 
cause the Surviving Corporation to maintain for a period of three years after 
the Effective Time the benefit plans of Nichols in effect on the date thereof 
(other than Option Plans) or to provide benefits to employees of Nichols that 
are no less favorable in the aggregate to such employees than those in effect 
on the date thereof. 

Employment Agreements. Prior to the Closing Date, Nichols will take all 
actions necessary and appropriate to amend the employment agreements between 
Nichols and certain of its employees identified in and in the manner 
described in an exhibit to the Merger Agreement. Corning or persons acting on 
its behalf shall meet with these employees of Nichols to discuss with such 
employees their employment arrangements and their opportunities and 
responsibilities after the Closing Date. See "Interests of Certain Persons in 
the Merger." Corning shall also cause the Surviving Corporation to honor 
without modification (except as provided in the section of the Merger 
Agreement described above) all terms and provisions of all employment 
agreements of these individuals in the form existing as of the date of the 
Merger Agreement. 

Closing Conditions 
Conditions to Each Party's Obligations to Effect the Merger. The Merger 
Agreement makes the respective obligation of each party to effect the Merger 
subject to the satisfaction or waiver on or prior to the Closing Date of the 
following conditions: 

  (i) the Nichols stockholders shall have adopted the Merger Agreement; 

  (ii) the Corning Common Shares issuable to the Nichols stockholders 
pursuant to the Merger Agreement and under the Stock Option Plans shall have 
been approved for listing on the NYSE, subject to official notice of 
issuance; 

  (iii) no litigation brought by a Governmental Entity shall be pending, and 
no litigation shall be threatened by any Governmental Entity, which seeks to 
enjoin or prohibit the consummation of the Merger, and no temporary 
restraining order, preliminary or permanent injunction or other order issued 
by any court of competent jurisdiction or other legal restraint or 
prohibition preventing the consummation of the Merger shall be in effect. For 
the purposes of the Merger Agreement a litigation shall be deemed to be 
"threatened" by the Federal Trade
<PAGE>
<PAGE>
 
Commission only if the Federal Trade Commission shall have publicly announced 
or shall have advised Corning, Merger Sub or Nichols that the Federal Trade 
Commission has authorized its staff to commence proceedings in Federal court 
seeking injunctive relief against, or to commence administrative proceedings 
challenging, the transactions contemplated by the Merger Agreement; 

  (iv) the Form S-4 shall have been declared effective by the SEC under the 
Securities Act. No stop order suspending the effectiveness of the Form S-4 
shall have been issued by the SEC, and no proceedings for that purpose shall 
have been initiated or, to the knowledge of Corning or Nichols, threatened by 
the SEC; 

  (v) the applicable waiting period (and any extension thereof) under the HSR 
Act shall have expired or been terminated; 

  (vi) other than the filing of merger documents in accordance with the DGCL, 
all authorizations, consents, waivers, orders or approvals required to be 
obtained, and all filings, notices or declarations required to be made, by 
Corning, Merger Sub and Nichols prior to the consummation of the Merger and 
the transactions contemplated hereunder shall have been obtained from, and 
made with, all required Governmental Entities except for such authorizations, 
consents, waivers, orders, approvals, filings, notices or declarations the 
failure to obtain or make which would not have a material adverse effect, at 
or after the Effective Time, on the Surviving Corporation or Corning. 

Additional Conditions to Obligations of Corning and Merger Sub. The Merger 
Agreement also makes the obligations of Corning and Merger Sub to effect the 
Merger subject to the following conditions: 

  (i) each of the representations and warranties of Nichols contained in the 
Merger Agreement shall, as of the Closing Date as though made on and as of 
the Closing Date, be true and correct except for such failures to be true and 
correct as could not, individually or in the aggregate, reasonably be 
expected to result in (i) a material adverse effect on Nichols or on Corning 
(except that where any statement in a representation or warranty, expressly 
includes a standard of materiality, such statement shall be true and correct 
in all respects giving effect to such standard) or (ii) an adverse effect on 
the ability of the parties to consummate the transactions contemplated by the 
Merger Agreement; provided that those representations and warranties which 
address matters only as of a particular date shall remain true and correct in 
all material respects (except that where any statement in a representation or 
warranty expressly includes a standard of materiality, such statement shall 
be true and correct in all respects giving effect to such standard) as of 
such date; 

  (ii) Nichols shall have performed or complied in all material respects with 
the agreements and covenants required by the Merger Agreement to be performed 
or complied with by it on or prior to the Closing Date; 

  (iii) Nichols shall have obtained the consent or approval of each person 
whose consent or approval shall be required in connection with the Merger 
under all loan or credit agreements, notes, mortgages, indentures, leases or 
other agreements or instruments to which it or any of its Material 
Subsidiaries is a party, except those for which failure to obtain such 
consents and approvals would not have a material adverse effect on Nichols 
prior to or after the Effective Time or a material adverse effect on Corning 
after the Effective Time; 

  (iv) Corning shall have received from Price Waterhouse, as independent 
auditors of Corning, on the date of the Proxy Statement and on the Closing 
Date, letters, in each case dated as of such respective dates, addressed to 
Corning, in form and substance reasonably acceptable to Corning and to the 
effect that the business combination to be effected by the Merger is required 
to be accounted for as a pooling-of-interests by Corning for purposes of its 
consolidated financial statements under generally accepted accounting 
principles and applicable SEC rules and regulations. No action shall have 
been taken by any Governmental Entity or any statute, rule, regulation or 
order enacted, promulgated or issued by any Governmental Entity, or any 
proposal made for any such action by any Governmental Entity which is 
reasonably likely to be put into effect, that would prevent Corning from 
accounting for the business combination to be effected by the Merger as a 
pooling-of-interests; 

  (v) Corning shall have received from each person who may be deemed to be an 
affiliate of Nichols (under Rule 145 of the Securities Act or otherwise under 
applicable SEC accounting releases with respect to pooling-of-interests 
accounting treatment) on or prior to the Closing Date a signed agreement 
substantially in the form of Exhibit 5.10 to the Merger Agreement. 

Additional Conditions to Obligations of Nichols. The Merger Agreement also 
makes the obligations of Nichols to effect the Merger subject to the 
following conditions: 

  (i) each of the representations and warranties of Corning contained in the 
Merger Agreement shall, as of the Closing Date as though made on and as of 
the Closing Date, be true and correct except for such failures
<PAGE>
<PAGE>
 
to be true and correct as could not, individually or in the aggregate, 
reasonably be expected to result in (i) a material adverse effect on Corning 
(except that where any statement in a representation or warranty expressly 
includes a standard of materiality, such statement shall be true and correct 
in all respects giving effect to such standard) or (ii) an adverse effect on 
the ability of the parties to consummate the transactions contemplated by the 
Merger Agreement; provided that those representations and warranties which 
address matters only as of a particular date shall remain true and correct in 
all material respects (except that where any statement in a representation or 
warranty expressly includes a standard of materiality, such statement shall 
be true and correct in all respects giving effect to such standard) as of 
such date; 

  (ii) Corning shall have performed or complied in all material respects with 
the agreements and covenants required by the Merger Agreement to be performed 
or complied with by it on or prior to the Closing Date; and 

  (iii)  Nichols shall have received the opinion of Fulbright & Jaworski 
L.L.P., counsel to Nichols, dated the date of the Proxy Statement, to the 
effect that the Merger will be treated for federal income tax purposes as a 
reorganization qualifying under the provisions of Section 368(a) of the 
Internal Revenue Code of 1986, as amended (the "Code"), which opinion shall 
not have been withdrawn or modified in any material respect. The issuance of 
such opinion shall be conditioned on the receipt of customary representation 
letters. 

Amendment; Termination 
Termination. The Merger Agreement may be terminated at any time prior to the 
Effective Time, whether before or after approval of matters presented in 
connection with the Merger by the stockholders of Nichols: 

  (i) by mutual written consent of Corning and Nichols; 

  (ii) by Corning, upon a breach of any representation, warranty, covenant or 
agreement, on the part of Nichols set forth in the Merger Agreement, or if 
any representation or warranty of Nichols shall have become untrue, in either 
case such that the conditions set forth in the sections of the Merger 
Agreement pertaining to the continued accuracy of Nichols' representations 
and warranties and Nichols' continued performance or compliance with all its 
covenants and agreements contained therein, as the case may be, would be 
incapable of being satisfied by November 30, 1994; provided that, in any 
case, a willful breach shall be deemed to cause such conditions to be 
incapable of being satisfied for purposes of termination of the Merger 
Agreement by Corning; 

  (iii) by Nichols, upon a breach of any representation, warranty, covenant 
or agreement on the part of Corning set forth in the Merger Agreement, or if 
any representation or warranty of Corning shall have become untrue, in either 
case such that the conditions set forth in the sections of the Merger 
Agreement pertaining to the continued accuracy of Corning's representations 
and warranties and Corning's continued performance or compliance with all its 
covenants and agreements contained therein, as the case may be, would be 
incapable of being satisfied by November 30, 1994; provided that in any case 
a willful breach shall be deemed to cause such conditions to be incapable of 
being satisfied for purposes of termination of the Merger Agreement by 
Nichols; 

  (iv) by either Corning or Nichols, if any Governmental Entity shall have 
issued an order, decree or ruling or taken any other action permanently 
enjoining, restraining or otherwise prohibiting the consummation of the 
Merger and such order, decree or ruling or other action shall have become 
final and nonappealable; 

  (v) by either Corning or Nichols, if the Merger shall not have occurred by 
November 30, 1994, unless the failure to consummate the Merger is the result 
of a breach of a covenant set forth in the Merger Agreement or a willful and 
material breach of any representation or warranty set forth in the Merger 
Agreement by the party seeking to terminate the Merger Agreement; 

  (vi) by Nichols, should the Exchange Ratio as calculated equal or exceed 
0.638 (see "Effect on Capital Stock"); or 

  (vii) by Corning at any time if Dr. Nichols loses control of sufficient 
shares of Nichols Common Stock such that the representations set forth in the 
Merger Agreement to the effect that the vote of Dr. Nichols' shares in favor 
of the Merger Agreement is sufficient to approve the Merger Agreement cease 
to be true and correct in all respects. 

Effect of Termination. In the event of termination of the Merger Agreement by 
either Nichols or Corning as provided in the terms of the Merger Agreement 
described in "Amendment; Termination," the Merger Agreement shall forthwith 
become void and have no effect, without any liability or obligation on the 
part of Corning, Merger
<PAGE>
<PAGE>
 
Sub or Nichols, other than the provisions of the Merger Agreement relating to 
Nichols' and Corning's representations as to their employment of brokers, 
their confidentiality agreement, their agreement as to fees and expenses, and 
certain general provisions of the Merger Agreement and except to the extent 
that such termination results from the willful and material breach by a party 
of any of its representations, warranties, covenants or agreements set forth 
in the Merger Agreement. 

Amendment. The Merger Agreement may be amended by the parties at any time 
before or after Nichols Stockholder Approval; provided, however, that after 
Nichols Stockholder Approval there shall not be made any amendment that by 
law requires further approval by the stockholders of Nichols without the 
further approval of such stockholders. The Merger Agreement may not be 
amended except by an instrument in writing signed on behalf of each of the 
parties. 

Extension; Waiver. At any time prior to the Effective Time, the parties may 
(a) extend the time for the performance of any of the obligations or other 
acts of the other parties, (b) waive any inaccuracies in the representations 
and warranties contained in the Merger Agreement or in any document delivered 
pursuant to the Merger Agreement or (c) subject to the proviso of the section 
of the Merger Agreement described in "Amendment; Termination", waive 
compliance with any of the agreements or conditions contained in the Merger 
Agreement. Any agreement on the part of a party to any such extension or 
waiver shall be valid only if set forth in an instrument in writing, signed 
on behalf of such party. The failure of any party to the Merger Agreement to 
assert any of its rights under the Merger Agreement or otherwise shall not 
constitute a waiver of those rights. 

Procedure for Termination, Amendment, Extension or Waiver. A termination of 
or amendment to the Merger Agreement or an extension or waiver pursuant to 
its terms shall, in order to be effective, require in the case of Corning, 
Merger Sub and Nichols, action by the relevant Board of Directors or the duly 
authorized designee of such Board of Directors. 

Agreement of Dr. Nichols to Vote in Favor of the Merger 
Concurrently with the execution of the Merger Agreement, Corning entered into 
the Dr. Nichols Letter Agreement, pursuant to which Dr. Nichols agreed to 
vote all shares of Nichols Common Stock that he has the right to vote in 
favor of approval of the Merger Agreement and the Merger at the Special 
Meeting. As of June 1, 1994, Dr. Nichols had the power to vote shares 
representing approximately 60% of the voting power of the Nichols Common 
Stock. 

In the Dr. Nichols Letter Agreement, Dr. Nichols also agreed, among other 
things, that until the Dr. Nichols Letter Agreement is terminated in 
accordance with its terms, he will not, and will not permit any entity 
controlled by him to, (i) convert any of his shares of Class B Common Stock 
into Class A Common Stock, (ii) contract to sell, sell or otherwise transfer 
or dispose of any of his shares or any interest therein or securities 
convertible thereinto or any voting rights with respect thereto, other than 
(x) pursuant to the Merger, (y) with Corning's prior written consent or (z) 
the use of shares as collateral pursuant to any loan arrangement previously 
disclosed to Corning to secure indebtedness up to specified limits, (iii) 
consent to any amendment to the certificate of incorporation of Nichols which 
would effectively reduce the proportionate voting power of his shares or (iv) 
to the extent any of his shares are subject to any encumbrances disclosed in 
writing to Corning, increase the amount of indebtedness secured by such 
shares beyond specified limits. 

A copy of the Dr. Nichols Letter Agreement is attached as Exhibit 5.16 to the 
Merger Agreement, a copy of which is attached as Appendix A. 

Certain Federal Income Tax Consequences 
It is a condition to the obligation of Nichols to consummate the Merger that 
Nichols receive an opinion from Fulbright & Jaworski L.L.P., tax counsel for 
Nichols, to the effect that (i) the Merger will be treated for federal income 
tax purposes as a reorganization within the meaning of Section 368(a) of the 
Code, (ii) no gain or loss will be recognized by Nichols as a result of the 
Merger and (iii) no gain or loss will be recognized by a Nichols stockholder 
as a result of the Merger with respect to shares of Nichols Common Stock 
converted solely into Corning Common Shares. The effects of any cash received 
in lieu of fractional share interests and any Real Property Tax Payments (as 
hereinafter defined) are discussed below. 

Based upon the advice of their respective counsel, Corning and Nichols expect 
that the Merger will qualify as a reorganization under the Code with the 
consequences set forth above. Assuming that the Merger so qualifies, the tax 
basis of the Corning Common Shares received by Nichols stockholders in the 
Merger will be the same, in each instance, as the tax basis of the Nichols 
Common Stock surrendered in exchange therefor, excluding any basis allocable 
to fractional share interests in Corning Common Shares for which cash is 
received. In addition, the holding period of the Corning Common Shares 
received in the Merger by Nichols stockholders will include the
<PAGE>
<PAGE>
 
period during which the shares of Nichols Common Stock surrendered in 
exchange therefor were held, provided that such shares of Nichols Common 
Stock were held as capital assets at the Effective Time. 

Holders of Nichols Common Stock who receive cash in the Merger as a result of 
the rounding off of fractional share interests in Corning Common Shares will 
be treated, in each instance, as having received the fractional share 
interests and then as having sold such interests for the cash received. This 
sale will result in the recognition of gain or loss for federal income tax 
purposes, measured by the difference between the amount of cash received and 
the portion of the basis of the share of Nichols Common Stock allocable to 
such fractional share interests. Such gain or loss will be capital gain or 
loss, provided that such share of Nichols Common Stock was held as a capital 
asset at the Effective Time, and will be long-term capital gain or loss if 
such share of Nichols Common Stock has been held for more than one year. 

Certain states and localities impose a tax on certain transfers (which 
include the Merger) of an interest in real property (including leases) 
located therein. Any returns required to be filed in connection with such tax 
will be filed by Nichols on behalf of the Nichols stockholders, and Nichols 
will pay any tax due thereon. The portion of any such payment attributable to 
a Nichols stockholder is referred to herein as a "Real Property Tax Payment." 

A Real Property Tax Payment, if any, should result in a deemed distribution 
by Nichols to a Nichols stockholder, which distribution would be taxed to 
such stockholder as a dividend to the extent of Nichols' current and 
accumulated earnings and profits as determined for federal income tax 
purposes (and thereafter would reduce the tax basis in his or her Nichols 
Common Stock and, if such basis is reduced to zero, would then be taxed as 
gain from the sale or exchange of such Nichols Common Stock). Any tax on such 
deemed distribution will be the responsibility of the Nichols stockholder. 

THE FOREGOING DISCUSSION IS INTENDED ONLY AS A SUMMARY OF CERTAIN FEDERAL 
INCOME TAX CONSEQUENCES OF THE MERGER AND DOES NOT PURPORT TO BE A COMPLETE 
ANALYSIS OR LISTING OF ALL POTENTIAL TAX EFFECTS RELEVANT TO A DECISION 
WHETHER TO VOTE IN FAVOR OF APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND 
THE MERGER. THE DISCUSSION DOES NOT ADDRESS THE TAX CONSEQUENCES THAT MAY BE 
RELEVANT TO A PARTICULAR NICHOLS STOCKHOLDER SUBJECT TO SPECIAL TREATMENT 
UNDER CERTAIN FEDERAL INCOME TAX LAWS, SUCH AS DEALERS IN SECURITIES, BANKS, 
INSURANCE COMPANIES, TAX-EXEMPT ORGANIZATIONS, NON-UNITED STATES PERSONS AND 
STOCKHOLDERS WHO ACQUIRED THEIR SHARES OF NICHOLS COMMON STOCK PURSUANT TO 
THE EXERCISE OF STOCK OPTIONS OR OTHERWISE AS COMPENSATION, NOR ANY 
CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCALITY OR FOREIGN 
JURISDICTION. MOREOVER, THE TAX CONSEQUENCES TO HOLDERS OF STOCK OPTIONS ARE 
NOT DISCUSSED. THE DISCUSSION IS BASED UPON THE CODE, TREASURY REGULATIONS 
THEREUNDER AND ADMINISTRATIVE RULINGS AND COURT DECISIONS AS OF THE DATE 
HEREOF. ALL OF THE FOREGOING ARE SUBJECT TO CHANGE AND ANY SUCH CHANGE COULD 
AFFECT THE CONTINUING VALIDITY OF THIS DISCUSSION. NICHOLS STOCKHOLDERS ARE 
URGED TO CONSULT THEIR OWN TAX ADVISORS CONCERNING THE FEDERAL, STATE, LOCAL 
AND FOREIGN TAX CONSEQUENCES OF THE MERGER TO THEM. 

Regulatory Approvals 
HSR Act and Antitrust. Corning and Nichols, and Dr. Nichols with respect to 
his acquisition of Corning Common Shares in the Merger, were required to 
observe the notification and waiting period requirements of the HSR Act 
before the Merger may be consummated. The HSR Act provides for an initial 
30-calendar day waiting period following the filing with the FTC and the 
Antitrust Division of certain Notification and Report Forms by the parties to 
the Merger and certain other parties. The HSR Act further provides that if, 
within the initial 30-calendar day waiting period, the FTC or the Antitrust 
Division issues a request for additional information or documentary material, 
the waiting period will be extended until 11:59 p.m. on the twentieth day 
after the date of substantial compliance by the filing parties with such 
request. Only one such extension of the initial waiting period is permitted 
under the HSR Act; however, the filing parties may agree not to close the 
transaction before a designated date. 

Corning, Nichols and Dr. Nichols have made the requisite filings under the 
HSR Act in connection withthe Merger, and the initial waiting periods with 
respect to such filings expired at 11:59 p.m., Eastern Time, onJuly 17, 1994. 

Resale of Corning Common Shares Issued in the Merger; Affiliates 
The Corning Common Shares to be issued to Nichols stockholders in connection 
with the Merger will be freely transferable under the Securities Act, except 
for Corning Common Shares issued to any person deemed to be an
<PAGE>
<PAGE>
 
affiliate of Nichols for purposes of Rule 145 under the Securities Act at the 
time of the Special Meeting ("Affiliates"). Affiliates may not sell their 
Corning Common Shares acquired in connection with the Merger except pursuant 
to an effective registration statement under the Securities Act covering such 
shares, or in compliance with Rule 145 promulgated under the Securities Act 
or another applicable exemption from the registration requirements of the 
Securities Act. Pursuant to the Merger Agreement, Nichols has agreed that 
prior to the Effective Time it will deliver to Corning a letter identifying 
all persons who at the time of the Special Meeting may be deemed to be 
Affiliates. Nichols has further agreed to use all reasonable efforts to cause 
each person who is so identified as an Affiliate in such letter to deliver to 
Corning on or prior to the date of this Proxy Statement/Prospectus a written 
agreement that such Affiliate will not sell, pledge, transfer or otherwise 
dispose of any Corning Common Shares received in the Merger in violation of 
the Securities Act, and that such Affiliate will not sell any Corning Common 
Shares or any shares of Nichols Common Stock until after such time as 
consolidated financial statements which reflect at least 30 days of 
post-Merger operations have been published by Corning (the date of such 
publication, the "Publication Date"). See "THE MERGER--Accounting Treatment." 

Accounting Treatment 
It is expected that the Merger will be accounted for as a pooling of 
interests for accounting and financial reporting purposes. It is a condition 
to the obligation of Corning to consummate the Merger that Corning receive 
the opinion of Price Waterhouse that the Merger can be accounted for as a 
pooling of interests. See "THE MERGER--Closing Conditions." 

Interests of Certain Persons in the Merger 
General. Nichols will be the Surviving Corporation in the Merger and, 
following the Merger, will be a wholly owned subsidiary of Corning. It is 
currently anticipated that certain executives of Nichols will continue in 
their current capacities. 

Dr. Nichols Employment Agreement. Concurrently with or as promptly as 
practical after the Effective Time, Corning will cause Nichols to enter into 
an employment agreement (the "Employment Agreement") with Dr. Nichols, 
Chairman of the Board of Nichols, pursuant to which Dr. Nichols will serve as 
Chairman Emeritus of the Surviving Corporation and will be a member of the 
Board of Directors of CLSI. The term of the Employment Agreement will be for 
a two-year period commencing on the Effective Time, subject to an additional 
three-year extension (the "Additional Term") if mutually agreed upon. As 
consideration for the Surviving Corporation's entering into the Employment 
Agreement, Dr. Nichols will agree to waive all rights to severance pay, 
damages or other payments due to the termination of his employment with the 
Surviving Corporation or as a result of the Merger, other than as set forth 
in the Employment Agreement. During the term of the Employment Agreement, Dr. 
Nichols will receive a base salary of $250,000 per year, payable in monthly 
installments. In addition, for each of the five years following the Effective 
Time, Dr. Nichols will receive a guaranteed lump sum bonus of $500,000, 
payable in arrears. At the end of the initial two-year employment period, Dr. 
Nichols will be eligible for an incentive bonus of between $1,000,000 and 
$2,000,000 based upon achievement of certain performance criteria for the 
Surviving Corporation. If the term of his employment is extended for the 
Additional Term, Dr. Nichols will be eligible for a similar incentive bonus 
in an amount to be agreed upon based on achievement of certain performance 
criteria for the Additional Term. Pursuant to the Employment Agreement, Dr. 
Nichols will also agree that, for a period of five years from the Effective 
Time, he will not compete with Corning in the clinical laboratory testing 
industry (including diagnostic testing) in the United States and he will not 
disclose any confidential information concerning the Surviving Corporation. 

Employment Agreement Amendments. In addition, to seek to assure Corning that 
certain key employees, including certain executive officers, some of whom are 
also directors, of Nichols, would remain with the Surviving Corporation 
during the critical transition period immediately subsequent to the Merger, 
Nichols, at Corning's request, agreed in the Merger Agreement to take all 
steps necessary and appropriate to amend the employment arrangements between 
Nichols and these key employees. It is anticipated that these will include: 
(i) an amendment to Mr. Bragg's (Chief Executive Officer) employment 
arrangement pursuant to which he will agree to waive severance benefits for 
voluntary departure within six months of the closing of the Merger and, 
thereafter, existing severance arrangements will apply; (ii) an amendment to 
Mr. Bellamy's (Chief Financial Officer and Senior Vice President) employment 
arrangement pursuant to which he will agree to waive severance benefits for 
voluntary departure within six months of the closing of the Merger and, 
thereafter, existing severance arrangements will apply; (iii) an amendment to 
Dr. Roberts' (Senior Vice President, Human Resources) employment arrangement 
pursuant to which he will agree to waive severance benefits for voluntary 
departure within six months of the closing of the Merger and, thereafter, 
existing severance arrangements will apply; (iv) an amendment to Dr. 
Harrington's (President, Reference Laboratories) employment arrangement 
pursuant to which he will agree to waive severance benefits for voluntary 
departure within two years of the closing of the Merger and, at the closing 
of the Merger, he will be offered a two-year employment contract (preserving 
existing severance arrangements for voluntary departure after two years) 
including participation in stock incentive plans; and (v) an amendment to Dr. 
Fisher's
<PAGE>
<PAGE>
 
(President, Nichols Academic Associates and Chief Science Officer) employment 
arrangement pursuant to which he will agree to waive severance benefits for 
voluntary departure within two years of the closing of the Merger and, at the 
closing of the Merger, he will be offered a two year employment contract 
(preserving existing severance arrangements for voluntary departure after two 
years) including participation in stock incentive plans. It is also intended 
that these amendments may include similar agreements with other key 
employees, including certain other executive officers. 

Stock Options. The Merger Agreement provides that, at the Effective Time, 
each option to purchase shares of Nichols Common Stock ("Stock Option") 
issued pursuant to any stock option plan of Nichols ("Option Plans") and then 
outstanding, whether or not vested or exercisable, will be assumed by Corning 
and will constitute an option to acquire, on the same terms and conditions as 
were applicable under such assumed Stock Option (other than to the extent 
accelerated pursuant to the terms of such Stock Option or in accordance with 
the present terms of any employment agreement existing as of the date of the 
Merger Agreement, which Stock Options will remain exercisable following the 
Effective Time in accordance with the provisions of the Option Plan under 
which they were granted), that number of Corning Common Shares equal to the 
product of the Exchange Ratio and the number of shares of Nichols Common 
Stock subject to such Stock Option, at a price per share equal to the 
aggregate exercise price for the shares of Nichols Common Stock subject to 
such Stock Option divided by the number of full Corning Common Shares deemed 
to be purchasable pursuant to such Stock Option; provided, however, that the 
number of Corning Common Shares that may be purchased upon exercise of such 
Stock Option will not include any fractional share. The vesting of certain 
Stock Options held by certain executive officers, some of whom are also 
directors, of Nichols to acquire shares of Class A Common Stock and Class C 
Common Stock accelerated upon execution of the Merger Agreement and certain 
other Stock Options will accelerate upon consummation of the Merger. 

The Merger Agreement provides that prior to the Closing the Nichols Board (or 
the relevant committee thereof) shall adopt such resolutions and Nichols 
shall obtain such written consents as may be necessary to rescind a pending 
amendment to the 1993 Non-Employee Director Stock Option Plan and all Stock 
Options granted thereunder to provide that the vesting of such Stock Options 
shall not be accelerated as a result of the Merger Agreement or the Merger. 
All necessary actions to rescind this pending amendment have been taken. 

As of June 30, 1994, Stock Options to purchase 74,990 and 2,416.416 shares of 
Class A Common Stock and Class C Common Stock, respectively, were outstanding 
under the Option Plans at exercise prices ranging from $4.125 to $15.125 per 
share. Based on the number of shares of Nichols Common Stock outstanding on 
the Record Date, assuming the exercise of all outstanding Stock Options 
(whether or not currently exercisable), and based upon the maximum Exchange 
Ratio permitted by the Merger Agreement, a maximum of 9,766,033 Corning 
Common Shares may be issued in connection with the Merger. For additional 
information regarding the Stock Options held by officers and directors, see 
"SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT OF NICHOLS." 

Indemnification of Directors and Officers Pursuant to the Merger 
Agreement. From and after the Effective Time, the Surviving Corporation will 
indemnify, defend and hold harmless the present and former officers, 
directors and employees of Nichols and its subsidiaries against all losses, 
expenses, claims, damages or liabilities arising out of actions or omissions 
occurring on or prior to the Effective Time to the full extent permitted or 
required under applicable law (except to the extent of directors' and 
officers' liability insurance coverage and actual payment with respect 
thereto). Corning has agreed to maintain for not less than six years the 
current (or appropriate replacement) policies of directors' and officers' 
liability insurance maintained by Nichols and its subsidiaries with respect 
to matters occurring prior to the Effective Time. Corning is not required to 
pay an annual premium for such insurance in excess of double the last annual 
premium paid prior to June 1, 1994, but will, in such case, purchase as much 
coverage as possible for such amount. 

Management and Operations of Nichols after the Merger 
After the Merger, the Surviving Corporation will be a wholly owned subsidiary 
of Corning. Nichols will operate as one of Corning's business units within 
the CLSI group, and Corning currently intends to retain Nichols' corporate 
headquarters in San Juan Capistrano, California. 

Expenses and Fees 
Whether or not the Merger is consummated, Corning and Nichols will each pay 
their own expenses in connection with the Merger. 

Appraisal Rights for Unlisted Stock Only 
Under the DGCL, holders of Class A Common Stock and Class C Common Stock will 
not be entitled to appraisal rights as a result of the Merger. Under the 
DGCL, appraisal rights are unavailable in a merger for shares of any class of 
stock which on the applicable record date for the stockholder vote on such 
merger are listed on a national securities exchange and which are to be 
converted into shares of stock of any other corporation listed on the 
effective date of the
<PAGE>
<PAGE>
 
merger on a national securities exchange. On the Record Date, the Class A 
Common Stock and Class C Common Stock are listed on the AMEX and it is a 
condition to consummation of the Merger that the Corning Common Shares 
continue to be listed on the NYSE. Accordingly, holders of the Class A Common 
Stock and the Class C Common Stock will not be entitled to appraisal rights 
as a result of the Merger. Further, stockholders who vote in favor of a 
merger are not entitled to appraisal rights under the DGCL as a result of 
such merger. 

Holders of record of the Class B Common Stock and of Nichols Preferred Stock 
(collectively, the "Unlisted Shares") who comply with the applicable 
statutory procedures summarized herein will be entitled to appraisal rights 
under Section 262 of the DGCL. A person having a beneficial interest in any 
Unlisted Shares held of record in the name of another person, such as a 
broker or nominee, must act promptly to cause the record holder to follow the 
steps summarized below properly and in a timely manner to perfect appraisal 
rights. 

The following discussion is not a complete statement of the law pertaining to 
appraisal rights under the DGCL and is qualified in its entirety by the full 
text of Section 262 which is reprinted in its entirety as Appendix D to this 
Proxy Statement/Prospectus. All references in Section 262 and in this summary 
to a "stockholder" are to the record holder of the Unlisted Shares as to 
which appraisal rights are asserted. 

Under the DGCL, holders of Unlisted Shares who follow the procedures set 
forth in Section 262 will be entitled to have their Unlisted Shares appraised 
by the Delaware Chancery Court and to receive payment in cash of the "fair 
value" of such Unlisted Shares, exclusive of any element of value arising 
from the accomplishment or expectation of the Merger, together with a fair 
rate of interest, if any, as determined by such court. 

Under Section 262, where a proposed merger is to be submitted for approval at 
a meeting of stockholders, the corporation, not less than 20 days prior to 
the meeting, must notify each of its stockholders who was such on the record 
date for such meeting with respect to shares for which appraisal rights are 
available, that appraisal rights are so available, and must include in such 
notice a copy of Section 262. 

This Proxy Statement/Prospectus constitutes such notice to the holders of 
Unlisted Shares and the applicable statutory provisions of the DGCL are 
attached to this Proxy Statement/Prospectus as Appendix D. Any stockholder 
who wishes to exercise such appraisal rights or who wishes to preserve his 
right to do so should review the following discussion and Appendix D 
carefully because failure to timely and properly comply with the procedures 
specified will result in the loss of appraisal rights under the DGCL. 

A holder of Unlisted Shares wishing to exercise such holder's appraisal 
rights (i) must, in the case of shares of Class B Common Stock, not vote in 
favor of adoption of the Merger Agreement and (ii) must, in the case of any 
Unlisted Shares, deliver to Nichols prior to the vote on the Merger Agreement 
at the Special Meeting to be held on August 31, 1994 a written demand for 
appraisal of such holder's Unlisted Shares. A holder of Unlisted Shares 
wishing to exercise such holder's appraisal rights must be the record holder 
of such Unlisted Shares on the date the written demand for appraisal is made 
and must continue to hold such Unlisted Shares of record until the Effective 
Time of the Merger. Accordingly, a holder of Unlisted shares who is the 
record holder of Unlisted Shares on the date the written demand for appraisal 
is made, but who thereafter transfers such Unlisted Shares prior to the 
Effective Time of the Merger, will lose any right to appraisal in respect of 
such Unlisted Shares. 

Only a holder of record of Unlisted Shares is entitled to assert appraisal 
rights for the Unlisted Shares registered in that holder's name. A demand for 
appraisal should be executed by or on behalf of the holder of record, fully 
and correctly, as such holder's name appears on such holder's stock 
certificates. If the Unlisted Shares are owned of record in a fiduciary 
capacity, such as by a trustee, guardian or custodian, execution of the 
demand should be made in that capacity, and if the Unlisted shares are owned 
of record by more than one person as in a joint tenancy or tenancy in common, 
the demand should be executed by or on behalf of all joint owners. An 
authorized agent, including one or more joint owners, may execute a demand 
for appraisal on behalf of a holder of record; however, the agent must 
identify the record owner or owners and expressly disclose the fact that, in 
executing the demand, the agent is agent for such owner or owners. A record 
holder such as a broker who holds Unlisted shares as nominee for several 
beneficial owners may exercise appraisal rights with respect to the Unlisted 
Shares held for one or more beneficial owners while not exercising such 
rights with respect to the Unlisted Shares held for other beneficial owners; 
in such case, the written demand should set forth the number of Unlisted 
shares as to which appraisal is sought and where no number of Unlisted Shares 
is expressly mentioned the demand will be presumed to cover all Unlisted 
Shares held in the name of the record owner. Stockholders who hold their 
Unlisted Shares in brokerage accounts or other nominee forms and who wish to 
exercise appraisal rights are urged to consult with their brokers to 
determine the appropriate procedures for the making of a demand for appraisal 
by such a nominee. 

All written demands for appraisal should be sent or delivered to Nichols 
Institute, 33608 Ortega Highway, San Juan Capistrano, CA 92690, Attention: 
Corporate Secretary.
<PAGE>
<PAGE>
 
Within 120 days after the Effective Time of the Merger, but not thereafter, 
the Surviving Corporation or any stockholder who has complied with the 
statutory requirements summarized above may file a petition in the Delaware 
Chancery Court demanding a determination of the fair value of the Unlisted 
Shares. Nichols is under no obligation to and has no present intention to 
file a petition with respect to the appraisal of the fair value of the 
Unlisted Shares. Accordingly, it is the obligation of the stockholders to 
initiate all necessary action to perfect their appraisal rights within the 
time prescribed in Section 262. 

Within 120 days after the Effective Time of the Merger, any stockholder who 
has complied with the requirements for exercise of appraisal rights will be 
entitled, upon written request, to receive from the Surviving Corporation a 
statement setting forth the aggregate number of shares of Class B Common 
Stock not voted in favor of adoption of the Merger Agreement, the aggregate 
number of Unlisted Shares with respect to which demands for appraisal have 
been received and the aggregate number of holders of such Unlisted Shares. 
Such statements must be mailed within ten days after a written request 
therefor has been received by the Surviving Corporation. 

If a petition for an appraisal is timely filed, after a hearing on such 
petition, the Delaware Chancery Court will determine the stockholders 
entitled to appraisal rights and will appraise the "fair value" of their 
Unlisted Shares, exclusive of any element of value arising from the 
accomplishment or expectation of the Merger, together with a fair rate of 
interest, if any, to be paid upon the amount determined to be the fair value. 
Stockholders considering seeking appraisal should be aware that the fair 
value of their Unlisted Shares as determined under Section 262 could be more 
than, the same as or less than the consideration they would receive pursuant 
to the Merger Agreement if they did not seek appraisal of the Unlisted Shares 
and that investment banking opinions as to fairness from a financial point of 
view are not necessarily opinions as to fair value under Section 262. The 
Delaware Supreme Court has stated that "proof of value by any techniques or 
methods which are generally considered acceptable in the financial community 
and otherwise admissible in court" should be considered in the appraisal 
proceedings. 

The Court will determine the amount of interest, if any, to be paid upon the 
amounts to be received by a person whose Unlisted Shares have been appraised. 
The costs of the action may be determined by the Court and taxed upon the 
parties as the Court deems equitable. The Court may also order that all or a 
portion of the expenses incurred by any stockholder in connection with an 
appraisal, including, without limitation, reasonable attorneys' fees and the 
fees and expenses of experts utilized in the appraisal proceeding, be charged 
pro rata against the value of all of the Unlisted Shares entitled to 
appraisal. 

Any holder of shares of Class B Common Stock who has duly demanded an 
appraisal in compliance with Section 262 will not, after the Effective Time 
of the Merger, be entitled to vote the shares of Class B Common Stock subject 
to such demand for any purpose. Any holder of Unlisted Shares who has duly 
demanded an appraisal in compliance with Section 262 will not, after the 
Effective Time of the Merger, be entitled to the payment of dividends or 
other distributions on those Unlisted Shares (except dividends or other 
distributions payable to holders of record of Unlisted Shares as of a record 
date prior to the Effective Time of the Merger). 

If any stockholder who properly demands appraisal of his Unlisted Shares 
under Section 262 fails to perfect, or effectively withdraws or loses, his 
right to appraisal, as provided in the DGCL, the Unlisted Shares of such 
stockholder will be converted into the right to receive the consideration 
receivable with respect to such Unlisted Shares in accordance with the Merger 
Agreement. A stockholder will fail to perfect, or effectively lose or 
withdraw, his right to appraisal if, among other things, no petition for 
appraisal is filed within 120 days after the Effective Time of the Merger, or 
if the stockholder delivers to the Surviving Corporation a written withdrawal 
of his demand for appraisal and acceptance of the Merger. Any such attempt to 
withdraw an appraisal demand more than 60 days after the Effective Time of 
the Merger will require the written approval of the Surviving Corporation. 

Failure to follow the steps required by Section 262 of the DGCL for 
perfecting appraisal rights may result in the loss of such rights (in which 
event a stockholder will be entitled to receive the consideration receivable 
to such Unlisted Shares in accordance with the Merger Agreement).

There is no established public trading market for the Class B Common Stock or 
the Nichols Preferred Stock. 

Nichols has never paid cash dividends on shares of Nichols Common Stock. 
Furthermore, Nichols' senior note agreements currently prohibit Nichols from 
paying cash dividends due to violations of certain financial covenants 
contained in these agreements. See "NICHOLS MANAGEMENT DISCUSSION AND 
ANALYSIS--Liquidity and Capital Requirements--Default on Senior Notes and 
loss of line of credit" and Note 3 in the consolidated financial statements 
of Nichols appearing elsewhere in this Proxy Statement/Prospectus. The Merger 
Agreement also restricts Nichols' ability to pay cash dividends between the 
date of the Merger Agreement and the Effective Time. 

On May 31, 1994, the last full trading day prior to announcement of the 
execution of the Merger Agreement, the reported AMEX Composite Transactions 
closing price per share of Class A Common Stock was $4.813 and the last

CORNING UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION 

The Unaudited Pro Forma Combined Financial Information (the "Unaudited Pro 
Forma Information") is presented to reflect the estimated impact on Corning's 
Financial Statements of the Corning Transactions as follows: 

* The acquisition of Nichols for an estimated 6.7 million Corning Common 
Shares and options to purchase approximately 1 million Corning Common Shares 
contemplated by this Proxy Statement/Prospectus. The acquisition will be 
accounted for as a pooling of interests. 

* The acquisition of Damon in August 1993, at a total purchase price of 
approximately $405 million, including acquisition expenses. The transaction 
has been accounted for as a purchase. 

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

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

* The issuance (the "MIPS Offering") by Corning Delaware L.P. ("Corning 
Delaware") of $373.8 million aggregate principal amount of Convertible 
Monthly Income Preferred Securities (the "Preferred Securities") completed in 
July 1994 and the use of the net proceeds thereof by Corning to retire the 
indebtedness incurred in connection with the Damon transaction. 

The Unaudited Pro Forma Combined Statements of Income for the year ended 
January 2, 1994, and the twenty-four weeks ended June 19, 1994, assume that 
the Corning Transactions had been completed on January 4, 1993. The Unaudited 
Pro Forma Combined Balance Sheet at June 19, 1994, assumes that the Corning 
Transactions had been completed by that date. Corning's consolidated 
financial statements for periods prior to the pooling of interests 
transactions will not be restated since the acquisitions are not material to 
Corning's financial position or results of operations. 

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

Corning has completed or has pending several business dispositions in 1994 
which individually and in the aggregate are not significant to Corning's 
consolidated financial statements. As such, pro forma data on these 
transactions are not presented. 

The Unaudited Pro Forma Information should be read in conjunction with the 
historical financial statements of Corning and Damon incorporated by 
reference into this Proxy Statement/Prospectus and the historical financial 
statements of Nichols included elsewhere in this Proxy Statement/Prospectus.

CORNING 
         NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION 

Note 1. -- Basis of Presentation: 
The Unaudited Pro Forma Combined Statements of Income reflect Corning's 
results of operations for the year ended January 2, 1994, and the twenty-four 
weeks ended June 19, 1994, on a pro forma basis assuming the Corning 
Transactions had been completed as of January 4, 1993. The Unaudited Pro 
Forma Combined Balance Sheet at June 19, 1994, assumes that the Corning 
Transactions had been completed by that date. 

Corning's management believes that the assumptions used in preparing the 
Unaudited Pro Forma Information provide a reasonable basis for presenting all 
of the significant effects of the Corning Transactions, that the pro forma 
adjustments give appropriate effect to those assumptions and that the pro 
forma adjustments are properly applied in the Unaudited Pro Forma 
Information. 

Note 2. -- Pro Forma Adjustments: 

Statement of Income 
(a) The pro forma adjustment to cost of sales represents the increase in 
amortization of the excess of cost over fair value of tangible net assets 
acquired in the Damon transaction, the Other 1993 Transactions and the 
Completed 1994 Acquisitions of $6.5 million, $1.8 million, and $6.0 million, 
respectively, for the year ended January 2, 1994, and $1.3 million for the 
Completed 1994 Acquisitions for the twenty-four weeks ended June 19, 1994. 

The excess of cost over fair value of tangible net assets acquired in the 
Damon transaction is $603 million. The excess of cost over fair value of 
tangible net assets acquired has been allocated to goodwill with a life of 
forty years. Management believes that fair value approximates book value for 
all tangible assets acquired in the Damon transaction. 

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

(b) The pro forma adjustment represents the elimination of one-time 
restructuring costs of $40.6 million related to closing MetPath facilities as 
a result of the integration of Damon and MetPath and $7.9 million of Costar 
transaction costs recorded in Corning's results for the year ended January 2, 
1994. 

(c) The pro forma adjustment to interest expense represents the interest on 
the debt incurred in connection with the Damon transaction and the Other 1993 
Transactions of $11.9 million and $2.3 million, respectively, for the year 
ended January 2, 1994. The weighted average interest rate on the debt 
incurred in connection with the Damon transaction is 4.9% and on the Other 
1993 Transactions ranges from 3.5% to 6.7%. 

Corning financed the Damon acquisition and the refinancing of approximately 
$167 million of indebtedness of Damon under short-term financing agreements 
entered into with certain banks to effect this transaction. During the third 
quarter of 1993, Corning refinanced a portion of this short-term financing by 
issuing approximately $200 million of longer-term debt. During the fourth 
quarter of 1993, Corning extended the terms of the financing agreements to 
December 31, 1995. The pro forma adjustment to interest expense related to 
the Damon transaction is calculated as the weighted average of short-term and 
longer-term interest rates. 

(d) The pro forma adjustment to interest expense reflects the decrease in 
interest expense assuming the issuance by Corning Delaware on January 4, 
1993, of $373.8 million of Preferred Securities pursuant to the MIPS Offering 
(net of an estimated $8.4 million of underwriting commissions and expenses), 
and the use of the net proceeds thereof by Corning to retire the indebtedness 
incurred in connection with the Damon transaction. 

(e) The pro forma adjustment represents the elimination of approximately $1 
million of one-time costs incurred by Damon in connection with a terminated 
merger agreement with National Health Laboratories Incorporated which were 
charged to results of operations for the seven months ended July 31, 1993. 

(f) The pro forma adjustment to tax expense represents the tax effect of the 
adjustments detailed in notes (a), (b), (c), (d) and (e) above. In addition, 
tax expense has been adjusted to provide taxes on the income of one of the 
Completed 1994 Acquisitions which was previously a Subchapter S corporation. 
These adjustments are calculated at Corning's historical effective tax rate. 

(g) The pro forma adjustment to minority interest represents the applicable 
minority interest on the historical earnings and pro forma adjustments of the 
Other 1993 Transactions and the Completed 1994 Acquisitions. 

(h) The pro forma adjustment to dividends on convertible preferred securities 
of subsidiary represents the after-tax dividends payable on the $373.8 
million of Preferred Securities pursuant to the MIPS Offering.
<PAGE>
<PAGE>
 
(i) The pro forma adjustment to weighted average shares outstanding 
represents the issuance of 5.5 million shares to complete the Costar 
acquisition in September 1993, 12.5 million shares in conjunction with the 
Completed 1994 Acquisitions and an estimated 6.7 million shares to be issued 
in conjunction with the Merger. 

The number of shares to be issued in the Merger is dependent on the price per 
Corning Common Share during a 10-day period prior to the date of the Nichols 
stockholders meeting to be held to approve the transaction. For purposes of 
this pro forma presentation, it is assumed that 6.7 million shares will be 
issued (based on a price of $33 per Corning Common Share and the current 
number of shares of Nichols Common Stock and options to purchase Nichols 
Common Stock outstanding). Pursuant to the agreement with Nichols, the 
maximum number of Corning Common Shares which could be issued is 
approximately 9.7 million shares (assuming the maximum Exchange Ratio of 
0.491 and exercise of all outstanding options). An increase in the number of 
shares to 9.7 million shares would not materially impact the pro forma 
earnings per share presented in the Unaudited Pro Forma Combined Statements 
of Income. 

Balance Sheet 
(j) The pro forma adjustment to loans payable beyond one year and preferred 
securities of subsidiaries assumes the issuance on June 19, 1994, of $373.8 
million of Preferred Securities pursuant to the MIPS Offering (net of an 
estimated $8.4 million of underwriting commissions and expenses), and the use 
of the net proceeds thereof by Corning to retire the indebtedness incurred in 
connection with the Damon transaction. 

Note 3. -- Earnings Per Share: 
Earnings per common share are computed by dividing net income less preferred 
dividends on Corning's Series B Preferred Stock by the weighted average of 
common shares outstanding during each period. Preferred dividends amounted to 
$2.1 million and $1.0 million during the year ended January 2, 1994, and the 
twenty-four weeks ended June 19, 1994, respectively. 

Note 4. -- Costar Merger: 
In September 1993, Corning acquired all of the outstanding shares of common 
stock and options to purchase common stock of Costar for approximately 5.5 
million Corning Common Shares and options to purchase approximately 300,000 
Corning Common Shares. This acquisition has been accounted for as a pooling 
of interests. Corning's consolidated financial statements for periods prior 
to the acquisition have not been restated since the acquisition is not 
material to Corning's financial position or results of operations. 

Note 5. -- Unilab Transaction: 
Corning, through a wholly owned subsidiary, owned 43% of Unilab. In November 
1993, Corning acquired 100 percent of certain Unilab facilities in exchange 
for a majority of the Unilab shares owned by Corning, the assumption of 
approximately $70 million of Unilab debt and Corning's investment in J.S. 
Pathology PLC ("J.S. Pathology"). Corning retained a 12% equity investment in 
Unilab. 

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

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

The accompanying notes are an integral part of these statements.

<PAGE>
 
(a) During the first quarter 1993, Corning recognized a non-operating gain 
totaling $4.2 million ($2.6 million after-tax). 

(b) Effective January 4, 1993, Corning and its subsidiaries adopted Financial 
Accounting Standard No. 109, " Accounting for Income Taxes" ("FAS 109") and 
Financial Accounting Standard No. 112, "Employers' Accounting for 
Postemployment Benefits" ("FAS 112"). The impact of adopting FAS 109 and FAS 
112 was not material to the financial statements. 

(c)  In 1993, Corning recognized net non-recurring losses from consolidated 
operations totaling $202.8 million ($117.9 million after-tax and minority 
interest), including a non-operating gain of $4.2 million ($2.6 million 
after-tax), a restructuring charge of $156.0 million ($88.1 million after-tax 
and minority interest) as a result of costs to integrate the Damon 
acquisition and a planned company-wide program to reduce assets and overhead 
costs during the next year and other special charges of $51.0 million ($32.4 
million after-tax). The other special charges primarily included $36.5 
million for the settlement and related legal expenses incurred in the 
compromise agreement between MetPath and the Civil Division of the Department 
of Justice and $8.0 million of transaction expenses related to the Costar 
acquisition. 
Corning also recorded a $203.1 million reduction in equity earnings as a 
result of a charge taken by Dow Corning Corporation ("Dow Corning") related 
to breast-implant litigation and a $9.5 million reduction in equity earnings 
as a result of a restructuring charge taken by Vitro Corning. 

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

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

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

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

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

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

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

(a) During 1992 and 1994, Nichols adopted the standards specified in 
Statements of Financial Accounting No. 109 "Accounting for Income Taxes" 
(SFAS 109) and No. 112 "Employers' Accounting for Postemployment Benefits" 
(SFAS 112), respectively. The adoption of SFAS 109 and SFAS 112 did not have 
a significant impact on previously reported amounts. 

(b) As of December 31, 1993 Nichols was not in compliance with certain 
covenants of its senior note agreements. The agreements provide that, as a 
result of the failure to comply with the covenants the holders of the senior 
notes have the right to declare the entire unpaid balance ($62.2 million) 
immediately due and payable. Accordingly, the senior notes have been 
classified as current, resulting in Nichols' reporting of a working capital 
deficit as of December 31, 1993 and as of March 31, 1994. 

(c) Net income (loss) per common and common equivalent share is based on the 
weighted average number of shares of Nichols Common Stock and, in 1989, 1990 
and 1991 and the three months ended March 31, 1993, common equivalent shares 
outstanding during the period. Common equivalent shares relate to Nichols 
Common Stock issuable upon the conversion of the Nichols Preferred Stock, 
upon the exercise of stock options and warrants and to be issued as future 
consideration for covenants not to compete. 

(d) In 1989, Nichols distributed a 5% stock dividend and then a 100% stock 
dividend. In 1990, Nichols distributed a 4% stock dividend. Per share 
information presented above has been adjusted to give retroactive effect to 
these dividends.

NICHOLS MANAGEMENT DISCUSSION AND ANALYSIS 

Traditionally, business acquisitions, primarily of Nichols' network of 
regional laboratories (the "Regional Laboratories"), have provided Nichols 
with significant strategic growth opportunities. Acquisitions contributed 
significantly to net revenue growth in 1991, continuing into the first half 
of 1992. During the latter half of 1992 and continuing into 1993, Nichols 
redirected its efforts to focus on improving the profitability and 
competitiveness of its existing operations rather than expanding its business 
through acquisitions. However, during 1992 and continuing into 1993, revenue 
growth was adversely impacted by intensified competitive industry pricing, 
increased consolidation and internalization of testing by clients, the 
continued industry trend to lower priced managed care plans and reduced tests 
per patient. Nichols believes these pressures on revenues will continue into 
1994 and subsequent years. In addition, in 1993 the government announced a 
reduction in reimbursement rates under its Medicare programs from 88%, which 
had been in effect for the past three years, to 76% of the fee schedule 
national ceilings effective over a two year period. Revenues, net of 
contractual allowances, from the Medicare and Medicaid programs approximated 
12% of total net revenues during 1991 and 13% during 1992 and 1993, 
respectively. Nichols believes pressure from reduced Medicare and Medicaid 
reimbursement rates will continue in the future. 

Nichols faces uncertainty with regard to the impact on its operations of 
federal and local legislation and proposed legislation such as the healthcare 
plan proposed by the Clinton Administration and other proposed plans. Until 
one of these plans or some form thereof is enacted into law, Nichols cannot 
make any assessment of the impact any such plans would have on Nichols, which 
could be material. Additionally, uncertainty exists as to how many tests will 
be affected by changes in its reimbursement policy of the Health Care 
Financing Administration ("HCFA") for certain medical diagnostic procedures 
ordered in connection with groups of tests recognized by HCFA for Medicare 
billing purposes and the pending investigation of industry practices with 
respect to such tests. See "BUSINESS OF NICHOLS--General--Healthcare 
Reimbursement," "--OIG Investigation" and "Liquidity and Capital 
Requirements--Contingencies." As a result, Nichols is unable to determine the 
extent of any adverse effect on Nichols' future revenues and profits from 
these matters. 

Results of Operations 

Three Months Ended March 31, 1994 Compared With Three Months Ended March 31, 
1993 
Net revenues.  Net revenues for the three months ended March 31, 1994 
declined to $69.6 million from $71.6 million in 1993, a decline of $2.0 
million or 2.8%. The revenues of the Regional Laboratories declined $1.3 
million or 3.4%, which was somewhat offset by marginally increased revenues 
of Nichols' centralized reference laboratories (the "Reference 
Laboratories"). The revenues of Nichols' diagnostics test kit division 
("Diagnostics") increased $0.7 million or 11.7% in the first quarter of 1994 
excluding the revenues associated with a ($1.2 million) contracted research 
and development arrangement and a separate licensing agreement undertaken in 
the first quarter of 1993 with a third party distributor. Nichols' operations 
have historically experienced a degree of seasonality with a softening in 
demand during the summer months and fourth quarter holiday season. 

After experiencing a sharp revenue decline early in the first quarter of 1994 
due to unseasonably cold weather, the Reference Laboratories' revenues 
strengthened late in the quarter largely from a change in the mix of tests 
performed. Nichols believes continued introduction of new and upgraded tests 
and the ability to differentiate its services from those of its competitors 
on the basis of quality and clinical correlations provide demand for the 
Reference Laboratories' services that are not as price sensitive as those 
laboratories which perform primarily routine tests such as the Regional 
Laboratories. 

Diagnostics' net revenues increased due to the continuing expansion of 
diagnostics test kit offerings during the past several years. 

Cost of sales.  Cost of sales increased to $46.5 million in 1994 from $44.4 
million in 1993, an increase of $2.2 million or 4.9%. In 1993 significant 
provisions were recorded for management incentive compensation and other 
employee benefit expenses. No similar provisions were recorded in 1994. 
Excluding these provisions and the revenues recorded in 1993 relating to 
Diagnostics' contracted research and development arrangement and the separate 
licensing agreement, cost of sales as a percentage of revenues was 66.8% in 
1994 compared to 61.7% in 1993. In absolute dollars, the cost increase was 
due to increased payroll expenses for merit and other labor related items, 
and, to a lesser extent, increased material costs due to vendor price 
increases. The cost of sales percentage increase was attributable to those 
cost increases spread over a declining 1994 revenue base. 

Selling, general and administrative expenses.  Selling, general and 
administrative expenses decreased to $18.5 million in 1994 from $18.7 million 
in 1993, a decrease of $0.2 million or 1.1%. Excluding the revenues 
associated with Diagnostics' contracted research and development arrangement 
and the separate licensing agreement, and the 1993 provisions for management 
incentives and other employee benefits which were not provided for in
<PAGE>
<PAGE>
 
1994, selling, general and administrative expenses, expressed as a percentage 
of revenues, marginally increased to 26.5% in 1994 from 25.6% in 1993. In 
absolute dollars, excluding the 1993 provisions for management incentives and 
other employee benefits, selling, general and administrative expenses 
increased in 1994 as the result of increases for merit and other labor 
related payroll expenses and, to a lesser extent, higher legal fees incurred 
in connection with Nichols' proposed public debt offering. Additionally, 
Diagnostics incurred higher sales and marketing costs as a result of the 
introduction of several of its new direct-chemiluminescent-technology-based 
products. 

Research and development.  Research and development expenditures declined to 
$0.9 million in 1994 from $1.1 million in 1993, a decrease of $0.2 million or 
17.4%. This decrease was primarily due to the completion of Diagnostics' 
activities in April 1993 under its contracted research and development 
arrangement with a third party distributor. 

Interest.  Interest costs decreased to $2.7 million in 1994 from $3.1 million 
in 1993, a decrease of $0.4 million or 14.3%. This decline was the result of 
Nichols having no short-term borrowings outstanding during 1994 and reducing 
its long-term debt on scheduled principal repayments since the first quarter 
of 1993. 

Unusual charges.  During the three months ended March 31, 1994 Nichols 
recorded unusual charges of $1.8 million consisting of significant legal and 
other related costs associated with the subpoena received in August 1993 from 
the Office of the Inspector General ("OIG") ($1.3 million) and professional 
and loan commitment fees in connection with its efforts to secure alternative 
financing ($0.5 million). Nichols expects these costs to continue through the 
end of 1994. See "Liquidity and Capital Requirements--Contingencies" and 
"Default on Senior Notes and loss of line of credit." 

Income taxes.  Nichols recorded a $0.2 million tax provision in 1994 on 
pre-tax loss of $1.3 million compared to a provision of $1.7 million in the 
first quarter of 1993, representing 45.0% of its recorded pre-tax income of 
$3.8 million during that period. Although Nichols recorded a pre-tax loss for 
1994, a provision for income taxes was recorded as a result of significant 
amortization of goodwill, which is not tax deductible, originating from 
previous business acquisitions. 

1993 Compared to 1992 

Net revenues  Net revenues declined to $279.6 million in 1993 from $284.2 
million in 1992, a decline of $4.6 million or 1.6%. Reference Laboratories' 
net revenues remained relatively constant in 1993 compared to 1992 and 
Regional Laboratories' net revenues declined in 1993. 

The decline in Regional Laboratories' net revenues was primarily due to the 
restructuring of Nichols' Dallas operations during 1992 and continuing 
through September 1993 (see Note 10 in the accompanying consolidated 
financial statements) and the significant revenue decline experienced by 
Nichols' other laboratories in Texas due to lost business, as the protracted 
period of uncertainty during negotiations concerning the sale of all of 
Nichols' Texas operations led to increased customer and staff attrition. 
Diagnostics revenues increased in 1993, primarily due to an ongoing extension 
of product offerings and expansion of international and domestic marketing 
efforts. 

Cost of sales.  Cost of sales declined to $175.3 million in 1993 from $179.2 
million in 1992, a decline of $3.9 million or 2.1%. Expressed as a percentage 
of net revenues, the 1993 cost of sales percentage of 62.7% remained 
relatively constant in comparison to the 1992 cost of sales percentage of 
63.0%. 

Although Nichols realized cost reductions in late 1992 and 1993 (see Selling, 
general and administrative expenses), the cost of sales percentage remained 
relatively constant between 1992 and 1993 largely as the result of laboratory 
costs which were spread over a declining 1993 revenue base. In absolute 
dollars, the decline in cost of sales during 1993 was primarily attributable 
to Company-wide cost reduction programs including reduced headcount, 
purchasing economies and restructuring of Nichols' Dallas operations (see 
Note 10 to the accompanying consolidated financial statements). 

Selling, general and administrative expenses.  Selling, general and 
administrative expenses declined to $75.2 million in 1993 from $75.8 million 
in 1992, a decline of $0.6 million or 0.8%. Expressed as a percentage of net 
revenues, selling, general and administrative expenses remained relatively 
constant at 26.9% in 1993 compared to 26.7% in 1992. 

Cost reduction programs implemented in late 1992 and in 1993 were largely 
offset by an increase in the cost of Nichols' self-insured group insurance 
program, higher bad debt expense, a full year's amortization of capitalized 
costs relating to the purchase of London Diagnostics, Inc. and an increase in 
professional fees. The cost reduction measures implemented in late 1992 
included salary reductions and freezes and suspension of vacation accruals 
and 401(k) matching contributions. Salary reductions were eliminated and 
vacation accruals were reinstated in January
<PAGE>
<PAGE>
 
1993, and salary freezes were lifted in April 1993. Additional cost reduction 
measures were implemented in August 1993, including the suspension of 
vacation benefits and executive salary reductions, which remained in effect 
through late November 1993. Additionally, there were no 401(k) matching 
contributions in 1993. 

Research and development.  Research and development expenses declined to $4.2 
million in 1993 from $5.0 million in 1992, a decrease of $0.8 million or 
14.7%. 

The decline was due primarily to the integration of London Diagnostics' 
research and development efforts with those of Nichols' existing kit research 
and development activities and the completion of activities under its 
contracted research and development arrangement (see Note 9 to the 
accompanying consolidated financial statements). 

Academic Associate fees and royalties.  Academic Associate fees and royalties 
increased to $2.8 million in 1993 from $2.5 million in 1992, an increase of 
$0.3 million or 8.6%. 

The increase was primarily due to the inclusion of compensation paid to 
Nichols' Chief Science Officer, who became primarily responsible for 
coordinating Nichols' Academic Associates efforts during that year. Prior to 
1993, the Chief Science Officer's compensation was recorded in selling, 
general and administrative expenses. 

Interest.  Interest costs decreased to $11.7 million in 1993 from $12.2 
million in 1992, a decrease of $0.5 million or 4.1%. 

The decline was the result of a substantial reduction in Nichols' average 
borrowings under its short-term financing arrangements. Nichols had no 
borrowings outstanding under its $15.0 million short-term financing 
arrangement from April 1993 through December 1993. The decline was partially 
offset by higher interest costs on Nichols' senior notes as a result of the 
full year's effect of the $10.0 million of senior notes issued in June 1992 
and the interest rate modifications on Nichols' $30.0 million and $27.0 
million senior notes effective in 1992 (see Note 3 in the accompanying 
consolidated financial statements). 

Provisions for restructuring and unusual charges.  In 1993, Nichols recorded 
provisions for restructuring and unusual charges of $12.8 million and $3.2 
million, respectively, and in 1992 a provision for restructuring of $13.0 
million. See "Restructuring and unusual charges--1991, 1992 and 1993" and see 
Note 10 to the accompanying consolidated financial statements. 

Equity in losses of partnership, net of restructuring provision.  Nichols 
recorded equity in losses of partnership of $1.4 million in 1992. See "Equity 
in losses of partnership--1991 and 1992." 

Other income.  Other income decreased to $0.2 million in 1993 from $0.4 
million in 1992. 

Income taxes.  Nichols recorded a $1.0 million income tax benefit in 1993, 
representing 19.1% of its recorded pre-tax loss in 1993 of $5.5 million, 
compared to a benefit of $0.1 million in 1992, representing 3.1% of its 
pre-tax loss of $4.4 million. 

Several factors had significant impacts on the effective tax rates reported 
by Nichols. For a reconciliation between the provision (benefit) for income 
taxes computed by applying the federal statutory tax rate to income (loss) 
before taxes and the actual provision (benefit) for income taxes, see Note 8 
in the accompanying consolidated financial statements. The benefit for income 
taxes was reduced as a result of amortization of goodwill originating from 
business acquisitions. 

As of December 31, 1993, Nichols had a net deferred tax asset of $0.4 
million. Although Nichols recorded net losses during 1992 and 1993 
principally as a result of restructuring charges recorded during those years 
(see "Restructuring and unusual charges--1991, 1992 and 1993"), Nichols 
expects to realize the benefit of the deferred tax asset through income from 
future operations and/or carryback to previous years. 

1992 Compared to 1991 

Net revenues.  Net revenues increased to $284.2 million in 1992 from $236.3 
million in 1991, an increase of $47.9 million or 20.3%. 

Reference Laboratories' net revenues increased in 1992 compared to 1991 due 
to the expansion of testing capabilities and increased sales of existing 
tests. Regional Laboratories' net revenues increased in 1992 largely due to 
the inclusion of full period results of businesses acquired in 1991 and an 
increase in the volume of tests performed. Diagnostics' net revenues 
increased in 1992 due to an increase in the volume of kits sold and the 
acquisition of London Diagnostics, Inc. in 1992 (see Notes 9 and 12 to the 
accompanying consolidated financial statements).
<PAGE>
<PAGE>
 
Cost of sales.  Cost of sales increased to $179.2 million in 1992 from $148.7 
million in 1991, an increase of $30.5 million or 20.5%. Expressed as a 
percentage of net revenues, the 1992 cost of sales percentage of 63.0% 
remained relatively constant in comparison to the 1991 cost of sales 
percentage of 62.9%. 

Selling, general and administrative expenses.  Selling, general and 
administrative expenses increased to $75.8 million from $63.4 million in 
1991, an increase of $12.4 million or 19.5%. Expressed as a percentage of net 
revenues, selling, general and administrative expenses remained relatively 
constant at 26.7% in 1992 versus 26.8% in 1991. 

The increase in selling, general and administrative expenses in 1992 was 
primarily due to the full year's occupancy of Nichols' new San Juan 
Capistrano facilities (see Note 4 in the accompanying consolidated financial 
statements), and, to a lesser extent, higher bad debt expense, the 
amortization of capitalized costs relating to the purchase of London 
Diagnostics, Inc., in 1992 and the relatively higher selling, general and 
administrative expenses of Nichols' newly acquired Bay Area (Oakland) 
laboratory. In addition, Nichols realized benefits from cost reduction 
measures implemented during the fourth quarter of 1992, including salary 
reductions and freezes, and the suspension of vacation accruals and 401(k) 
matching contributions offset somewhat by costs associated with a 
reorganization of Nichols' management structure. The salary reductions were 
eliminated and vacation accruals were restored in January 1993. 

Research and development.  Research and development expenditures increased to 
$5.0 million in 1992 from $3.0 million in 1991, an increase of $2.0 million 
or 67.6%. 

The increase was primarily due to the acquisition of London Diagnostics, Inc. 
in 1992, which performed contract research and development for one of its 
customers (see Notes 9 and 12 to the accompanying consolidated financial 
statements). 

Academic Associate fees and royalties.  Academic Associate fees and royalties 
decreased to $2.5 million in 1992 from $3.0 million in 1991, a decrease of 
$0.5 million or 16.2%. 

The decrease was due to the expiration of certain royalty contracts in late 
1991. 

Interest.  Interest costs increased to $12.2 million in 1992 from $6.7 
million in 1991, an increase of $5.5 million or 82.9%. 

The increase was largely due to the inclusion of a full year's effect of 
interest on the capital lease for the San Juan Capistrano facilities and on 
the $30.0 million senior notes issued in 1991. In addition, Nichols increased 
its average borrowings under its $15.0 million short-term financing 
arrangement, issued an additional $10.0 million of senior notes in June 1992 
and assumed additional debt in connection with the consolidation of the 
Dallas operations (see Note 10 to the accompanying consolidated financial 
statements). 

Provision for restructuring and equity in restructuring provision of 
partnership.  In 1992 and 1991 Nichols recorded provisions for restructuring 
of $13.0 million and $0.9 million, respectively. In addition, Nichols 
recorded equity in restructuring provision of partnership of $2.9 million in 
1991 (see "Restructuring and unusual charges--1991, 1992 and 1993"). 

Equity in losses of partnership, net of restructuring provision.  Nichols 
recorded equity in losses of partnership of $1.4 million in 1992 and $2.2 
million (net of restructuring provision of $2.9 million) in 1991 (see "Equity 
in losses of partnership--1991 and 1992" and "Restructuring and unusual 
charges--1991, 1992 and 1993"). 

Other income.  Other income decreased to $0.4 million in 1992 from $0.9 
million in 1991 primarily due to lower interest income. 

Income taxes.  Nichols recorded a $0.1 million income tax benefit in 1992, 
representing 3.1% of its recorded pre-tax loss in 1992 of $4.4 million, 
compared to income taxes of $3.0 million in 1991, representing 47.2% of its 
recorded pre-tax income of $6.4 million in 1991. 

Several factors had significant impacts on the effective tax rates reported 
by Nichols. For a reconciliation between the provision (benefit) for income 
taxes computed by applying the federal statutory tax rate to income (loss) 
before taxes and the actual provision (benefit) for income taxes, see Note 8 
in the accompanying consolidated financial statements. Although Nichols 
recorded a pre-tax loss for 1992, the benefit for income taxes was only 3.1% 
of the pre-tax loss largely as a result of amortization of goodwill 
originating from business acquisitions. The 1992 benefit for income taxes was 
also reduced as a result of significant goodwill write-offs recorded in that 
year. 

Equity in losses of partnership--1991 and 1992 
During 1990 Nichols formed a joint venture partnership, Nichols Institute 
Laboratories North Texas, Ltd. (the "Dallas operations"), of which Nichols 
was the general partner.
<PAGE>
<PAGE>
 
During 1991 Nichols' share (based upon its share of equity) in the losses of 
the Dallas operations increased to $5.1 million due to substantial operating 
losses and restructuring charges associated with the write-down of customer 
lists and fixed assets and provisions for closing certain facilities. 
Nichols' recorded share of the Dallas operations' restructuring charges ($2.9 
million) substantially exceeded its proportionate interest in such costs. 
This condition resulted from the exhaustion of the joint venture partners' 
capital contributions during 1991 and a provision of the partnership 
agreement which required that Nichols, as general partner, absorb 100% of 
cumulative losses in excess of partner contributions. 

During the first quarter of 1992, the Dallas operations continued to 
experience significant operating losses, which Nichols fully absorbed. In 
order to obtain the control necessary to stem the significant operating 
losses of the Dallas operations, in April 1992 Nichols acquired the limited 
partners' interests in the operations in exchange for 225,000 shares of Class 
C Common Stock valued at $2.1 million. As of that date, the assets and 
liabilities of the Dallas operations were consolidated with those of Nichols, 
as were the Dallas operations' revenues and operating losses through the end 
of the second quarter. Nichols' equity in losses of the Dallas operations 
prior to its consolidation was $1.4 million in 1992. See "Restructuring and 
unusual charges--1991, 1992 and 1993." 

Restructuring and unusual charges--1991, 1992 and 1993 
In addition to recording its equity in losses of the Dallas operations (see 
"Equity in losses of partnership--1991 and 1992"), in 1991 Nichols recorded a 
direct restructuring charge of $0.9 million relative to its Dallas operations 
relating primarily to provisions for severance pay. 

In 1992, Nichols decided that operating losses of the Dallas operations could 
only be reduced by significantly downsizing the Dallas operation. 
Accordingly, Nichols recorded a restructuring charge of $13.0 million as of 
June 30, 1992 to provide for the estimated costs of effecting the downsizing. 
Nichols continued to refine the components of the restructuring charge until 
December 31, 1992, at which time the restructuring charge was composed of a 
provision for write-downs of assets that were expected to be impaired as a 
result of the downsizing of the Dallas operations ($1.5 million), a partial 
write-down of customer lists ($2.4 million) and write-down of goodwill 
established upon the purchase of the limited partners' interest in the Dallas 
operations ($2.7 million), provisions for future losses of the Dallas 
operations through the estimated date of completion of the downsizing ($4.4 
million), severance pay and related costs ($0.5 million), costs associated 
with subleasing the Dallas facility ($0.7 million), professional fees ($0.5 
million) and other related costs ($0.3 million). The downsizing of the Dallas 
operations contemplated by the 1992 restructuring was largely complete as of 
September 30, 1993, with the Dallas operations essentially closed down and 
retaining only a limited local presence. The amounts ultimately incurred 
related to the 1992 restructuring charge were not significantly different 
than those contemplated by Nichols. 

The 1992 restructuring charge contemplated that Nichols would sublet the 
entire Dallas facility to an interested third party. These negotiations, 
however, were terminated in late 1993. Subsequently, Nichols decided it was 
not practicable to continue pursuing the sublease opportunities and paid $1.8 
million as settlement to terminate the lease on January 31, 1994. Termination 
costs of the lease, in excess of those contemplated during the 1992 
restructuring, are included in the restructuring charge recorded by Nichols 
in 1993 as described below. 

Beginning in the third quarter of 1992 Nichols was also in discussions with 
prospective buyers for all of the Texas operations. Nichols ultimately 
decided not to sell because it could not reach agreement with any buyer on 
terms which it considered acceptable. While the sale discussions were 
pending, each of the Texas laboratories experienced a decline in revenues and 
increased operating losses. In 1994, Nichols' Texas operations have begun to 
recover the revenues lost during the sales discussions. 

During 1993, Nichols initiated standardization of those operating, 
administrative and financial processes necessary to implement the 
consolidation and integration required to significantly improve the 
profitability of its various acquired laboratories, and in the fourth quarter 
of 1993 recognized a restructuring charge of $12.8 million in connection with 
Nichols' plan to consolidate its Texas, Bay Area (Oakland) and Upper Midwest 
regional laboratory operations, further automate the operations of the 
Reference Laboratories and abandon efforts to sublease its primary Dallas 
facility, as noted above. This plan resulted in Nichols establishing a $12.8 
million restructuring reserve in the fourth quarter of 1993. The charge 
included write-offs of customer lists of Regional Laboratories impaired as a 
result of the restructuring ($1.9 million) and write-offs of property and 
other assets ($1.5 million) impaired as a result of the downsizing in certain 
of the locations, as well as provisions for severance pay, outplacement fees 
and related costs ($4.4 million), costs of terminating excess facilities and 
equipment leases ($3.0 million, which included $1.8 million paid as 
settlement for terminating the Dallas facility lease on January 31, 1994), 
strategic and financial consulting services incurred as of December 31, 1993 
($0.9 million), professional fees ($0.3 million) and other costs associated 
with the restructuring of Nichols' operations ($0.8 million). In evaluating 
the permanent impairment of assets as a result of the restructuring, Nichols 
considered whether the fair value exceeded the net
<PAGE>
<PAGE>
 
book value of the assets to be sold, abandoned or which were duplicative in 
nature or, in the case of intangibles, whether future anticipated cash flows 
from the assets would support the remaining carrying value. 

The consolidation and automation efforts contemplated in the 1993 
restructuring charge are intended to eliminate duplicative functions and 
equipment, reduce labor, facilities and other operating costs and are 
intended to provide for improved operating and marketing efficiencies. 
Nichols expects that the implementation of the restructuring plan will result 
in the consolidation of its facilities in Houston, San Antonio and El Paso, 
Texas; Mankato and St. Cloud, Minnesota; Des Moines, Iowa; and Bay Area 
(Oakland), California. Additionally, Nichols expects the number of management 
and staff employees to be reduced by approximately 10%. 

Implementation of the 1993 restructuring programs is presently under way and 
is expected to be substantially complete by the end of 1994. These programs 
will require significant cash expenditures which Nichols estimates will 
approximate $9.6 million, of which approximately $1.8 million was expended 
during 1993, approximately $7.0 million is expected to be expended during 
1994 and the remainder is expected to be expended thereafter. Nichols 
anticipates that the cash requirements of the 1993 restructuring plan will be 
satisfied through cash generated from operations. During the three months 
ended March 31, 1994, approximately $2.3 million was expended. Nichols 
anticipates that successful implementation of the restructuring programs, 
largely through consolidation and integration of certain of its currently 
decentralized and fragmented operations, should both significantly improve 
sales and marketing efforts and result in expense reductions. As Nichols 
continues to standardize on to common marketing, operating and administrative 
platforms, it expects to realize expense reductions exceeding $9.0 million 
annually, with $4.0 million realizable in 1994. The most significant expense 
reductions will be derived from the reductions in workforce and facilities 
which Nichols anticipates will provide 1994 expense reductions of $3.1 
million and $0.7 million, respectively, and, thereafter, $7.7 million and 
$0.9 million, respectively. Cash flow benefits are expected to approximate 
those of the expense reductions. The adequacy of the balance of the 
restructuring reserve as of March 31, 1994 and the realization of the 
anticipated future benefits depends largely on Nichols' ability to 
successfully complete the downsizing and consolidation of certain of its 
laboratories, particularly those in Texas. To date, the 1993 restructuring 
programs are largely progressing as was contemplated when the restructuring 
charge was recorded in the fourth quarter of 1993. 

In the fourth quarter of 1993, Nichols recorded unusual charges of $3.2 
million consisting primarily of the write-off of impaired assets, including 
customer lists of approximately $1.6 million acquired in connection with 
Nichols' Bay Area (Oakland) laboratory and certain fixed assets of 
approximately $0.6 million, the value of which had been impaired. The charge 
also included the expenses incurred through December 31, 1993 with respect to 
responding to the OIG subpoena (see "BUSINESS OF NICHOLS--General--OIG 
Investigation" and Note 11 to the accompanying consolidated financial 
statements). Substantial additional costs are expected to be incurred during 
1994 in connection with responding to the OIG subpoena. 

Liquidity and Capital Requirements 
Default on senior notes and loss of line of credit.  Nichols' senior note 
agreements (see Note 3 in the accompanying consolidated financial statements) 
require that Nichols satisfy certain financial and other covenants. As a 
result of operating losses in both the fourth quarter of 1993 and in the 
first quarter of 1994, Nichols was in violation of certain financial 
covenants under its senior note agreements at December 31, 1993 and March 31, 
1994. Although Nichols has made substantial improvements in its cash position 
over the past year, Nichols does not expect to meet existing or future 
financial covenant requirements under the senior note agreements. The senior 
note agreements provide that, as a result of Nichols' failure to meet the 
covenants, the senior noteholders have the right to declare the outstanding 
balance of all of the senior notes immediately due and payable, and if that 
were to occur, Nichols would not have the funds required to retire the debt 
unless alternative financing is obtained. Pursuant to the terms of the Merger 
Agreement, Corning has agreed to repay, or cause the Surviving Corporation to 
repay, the Senior Notes. The accompanying condensed consolidated financial 
statements have been prepared assuming that Nichols will continue as a going 
concern. This basis contemplates the realization of Nichols' assets and 
satisfaction of liabilities in the normal course of conducting business. The 
financial statements do not include any adjustments that might result in the 
event the debt is accelerated except for the classification of amounts due 
under the senior notes as current. No assurances can be given that the senior 
note holders will not accelerate the senior notes prior to the expected 
repayment and, if the Merger is not consummated, no assurances can be given 
that alternative financing can be obtained. 

To date, Nichols has made all payments required under the terms of its senior 
note agreements and all of its other debt instruments. Nichols is scheduled 
to make principal and interest payments on the senior notes of $7.7 million 
and $3.0 million in the second and fourth quarters of 1994, respectively, and 
$11.7 million in the second quarter of 1995. Although Nichols believes that 
near term senior note obligations will be satisfied by cash generated 
internally from operations assuming the senior notes are not accelerated, no 
assurances can be given that these obli
<PAGE>
<PAGE>
 
gations will be met. In the event the senior noteholders exercise the right 
to accelerate payment on the remaining senior note balances, Nichols will not 
be able to satisfy its obligations scheduled under the senior notes 
agreements on a timely basis unless alternative financing arrangements are 
secured. 

During 1993, Nichols renewed its $15.0 million credit agreement with a 
domestic bank. The agreement, which was to expire on June 1, 1994, provided 
for unsecured borrowings at the prime interest rate plus one-fourth of one 
percent. No borrowings had been outstanding under the agreement since April 
1993. As a result of Nichols' operating loss during the fourth quarter of 
1993, Nichols was in default under the terms of the credit agreement and the 
line was canceled. If the Merger is not consummated, Nichols considers the 
availability of a bank line to be prudent to insure its ability to satisfy 
its working capital needs and meet other short-term obligations. No 
assurances can be given that a bank line would be available. Nichols also had 
a revolving credit agreement with a German bank which expired as of December 
31, 1993. 

Capital requirements.  Traditionally, Nichols' principal capital requirements 
have been for debt service and capital expenditures. During 1993 and 
continuing into the first quarter of 1994, property additions significantly 
declined over 1992 and prior years as a result of capital spending control 
measures observed by Nichols. Although these measures will continue through 
the remainder of 1994, Nichols anticipates investing substantial sums in 
computer systems, hardware and software in the future. Business acquisitions 
represented a significant portion of Nichols' capital requirements in 1991 
and 1992; however, Nichols did not engage in any new acquisitions in 1993 or 
in the first quarter of 1994 as it pursued a strategy of improving existing 
operations. Nichols has financed its capital requirements over the last three 
years primarily with cash generated from operations and borrowings. Capital 
requirements during the first quarter of 1994 were financed with cash 
generated from operations. 

During the past several years, Nichols has invested significant resources to 
expand the computerization of its various laboratory, manufacturing and 
financial and communications information systems which increasingly represent 
a significant competitive factor in the laboratory testing industry. Nichols 
is undertaking a comprehensive review of its systems with the intention of 
implementing a complete upgrade and integration of its laboratory, financial 
information and other communications systems consistent with the need to 
provide prompt diagnostic information at lower cost. 

Repayment of Nichols' debt, including the senior notes, the repayment of 
other obligations, the need to continue to improve, integrate and standardize 
its laboratory operations, information systems, administration and marketing 
activities, the development and integration of new computerization of its 
laboratory, financial information and communications systems, the further 
automation of operations and the implementation of other operational and 
strategic changes, including the 1993 restructuring plan, will require 
substantial cash expenditures in the future. 

Assuming that the senior notes are not accelerated, Nichols believes that 
present cash flow from operations, supplemented with cost reduction measures 
being undertaken by Nichols, should be sufficient to meet operating and 
capital requirements in the short term. Additionally, Nichols continues to 
evaluate its capital structure in light of its anticipated future needs to 
move Nichols forward competitively. If the Merger is not consummated, Nichols 
would consider it prudent to obtain a working capital line for any major 
unforeseen short term cash shortfalls. No assurances can be given that a 
working capital line could be obtained. Regardless of whether the senior 
noteholders accelerate their notes, Nichols cannot assure that the remaining 
obligations under the senior note agreements will be satisfied on a timely 
basis if the senior notes are not repaid in connection with the Merger. 

Cash flows from operating activities.  Cash flows from operations decreased 
to $6.0 million for the three-month period ended March 31, 1994 from $7.6 
million for the three-month period ended March 31, 1993. The decrease was due 
to earnings decline of $3.7 million largely offset by an increase in accounts 
payable associated with the continued strengthening of cash management 
practices. 

Cash flows from operations increased to $28.3 million in the year ended 
December 31, 1993 from $19.5 million in the year ended December 31, 1992 
primarily due to a decrease in working capital. The working capital decrease 
arose principally from a decline in accounts receivable relating to lower 
sales levels during the latter part of 1993 as compared to 1992, and 
increased accounts payable associated with strengthened cash management 
practices, partially offset by inventory increases associated with the growth 
in Diagnostics' product and instrumentation offerings and a net decrease in 
accrued liabilities relating to the timing of payment of payroll, interest, 
and restructuring and unusual charges. Cash flows from operations increased 
to $19.5 million in the year ended December 31, 1992 from $12.0 million in 
the year ended December 31, 1991 primarily due to increased revenues in 1992. 

Cash flows from investing activities.  Net cash used by investing activities 
amounted to $1.5 million for the three-month period ended March 31, 1994 and 
$1.7 million for the three-month period ended March 31, 1993. Dur
<PAGE>
<PAGE>
 
ing the three months ended March 31, 1993, Nichols expended cash of $0.4 
million for payments made in connection with previous business acquisitions, 
exclusive of repayments of acquisition indebtedness. No such payments have 
been made in 1994. Additionally, Nichols expended $1.5 million and $1.3 
million for equipment purchases during the three months ended March 31, 1994 
and 1993, respectively. For each of the three-month periods ended March 31, 
1993 and March 31, 1994, cash requirements for covenant payments, and 
acquisitions of property and equipment were satisfied through cash from 
operations. 

Net cash used by investing activities amounted to $59.5 million in the year 
ended December 31, 1991, $21.1 million in the year ended December 31, 1992 
and $8.4 million in the year ended December 31, 1993. 

As discussed in Note 4 in the accompanying consolidated financial statements, 
Nichols relocated its San Juan Capistrano based Reference Laboratories, 
research and development and administrative activities to new facilities 
during the third quarter of 1991. The agreements between Nichols and the 
developer of these facilities include a lease of a portion of Nichols' land 
to the developer and a leaseback of the land and buildings by the developer 
to Nichols. The amount of rent payable under the leaseback is approximately 
$3.8 million per year. The transaction has been accounted for as a capital 
lease commencing in August 1991. The total cost of the new facilities, 
including water and sewer facilities which are maintained and operated by the 
utility company and significant amounts of fixtures, equipment and 
furnishings, approximated $61.0 million, of which approximately $8.0 million 
(land and development costs) was incurred prior to 1991. Of the 1991 costs, 
approximately $32.5 million was financed under the capital lease. 

During the three years ended December 31, 1993, Nichols expended cash of 
$19.8 million, $3.2 million and $0.4 million, respectively, in connection 
with business acquisitions (see Note 12 in the accompanying consolidated 
financial statements), exclusive of repayments of acquisition indebtedness. 
The cash requirements for 1991 business acquisitions were satisfied 
principally using a portion of the proceeds of a 1990 stock offering and the 
1991 senior debt issuance (see "Cash flows from financing activities"). 
Amounts expended during 1992 were satisfied using proceeds of the 1991 and 
1992 senior debt issuances and borrowings under Nichols' bank financing 
agreement. The 1993 cash requirements were satisfied through cash from 
operations. In connection with its acquisition of London Diagnostics, Inc. in 
1992, Nichols gained access to a non-isotopic methodology which has been 
incorporated into its line of diagnostic test kits, which is being used with 
semi-automated instrumentation. Nichols is considering development of fully 
automated instrumentation which will allow the processing of patient 
specimens that would significantly enhance the benefits of this techology 
without significant incremental labor expense. Development of the fully 
automated instrumentation would require Nichols to commit substantial 
financial resources and to obtain financing to fulfill the capital 
requirements. However, Nichols currently has no formal plan to develop or 
fund such fully automated instrumentation. 

In connection with the financing of the Dallas operations, Nichols made 
capital contributions and advances totaling $3.0 million and $0.4 million, 
respectively, through April 13, 1992, the date at which Nichols purchased the 
limited partners' interests in the Dallas operations. Commencing at that time 
the assets, liabilities, and operating results of the Dallas operations were 
consolidated with those of Nichols. See "Results of Operations--Equity in 
losses of partnership--1991 and 1992" and "Results of 
Operations--Restructuring and unusual charges--1991, 1992 and 1993." 

Cash flows from financing activities.  Net cash used by financing activities 
was $0.6 million for the three-month period ended March 31, 1994 and $5.9 
million for the three-month period ended March 31, 1993. During the three 
months ended March 31, 1994, Nichols made scheduled principal payments on its 
long-term debt of $0.7 million. During the three months ended March 31, 1993, 
Nichols made net repayments under bank financing arrangements of $3.6 
million, and principal payments on long-term debt and capital leases of $2.3 
million. The cash used by investing activities for both periods were 
satisfied by cash generated from operations. 

Net cash provided (used) by financing activities was $35.8 million in the 
year ended December 31, 1991, ($0.6) million in the year ended December 31, 
1992 and ($13.8) million in the year ended December 31, 1993. 

On June 7, 1991, Nichols issued $30.0 million of senior notes. The proceeds 
of this issuance were used principally to finance business acquisitions and 
certain costs of the then new San Juan Capistrano facilities. On June 18, 
1992 Nichols issued an additional $10.0 million of senior notes. The proceeds 
of this issuance were used primarily to repay a portion of Nichols' 
borrowings under its then $15.0 million short-term bank financing 
arrangement. 

Contingencies 

IRS.  The Internal Revenue Service ("IRS") is examining Nichols' tax returns 
for the calendar years 1988 through 1992. The IRS has challenged certain 
deductions of Nichols relating primarily to acquired customer lists
<PAGE>
<PAGE>
 
and covenants not to compete entered into in connection with business 
acquisitions. Although the amounts involved would be significant if the 
deductions are ultimately disallowed, Nichols believes that the deductions 
were valid and that this matter will not have a material adverse effect on 
its financial condition or results of operations. On October 20, 1993 Nichols 
filed a protest with the IRS against the disallowance of these tax deductions 
and has requested a hearing with the IRS Appellate Conference on the matter. 
In April 1994, Nichols received a proposed settlement from the IRS regarding 
the deduction of customer lists acquired in connection with Nichols' Dallas 
operations which have been closed down. Nichols is currently evaluating the 
settlement offer. 

Although Nichols is unable to predict the outcome of this matter and has 
therefore not recorded any losses associated with this examination, Nichols 
does not believe resolution of this matter will have a material adverse 
effect on its financial condition or results of operations. 

OIG Investigation.  On August 30, 1993, Nichols received a subpoena from the 
Office of the Inspector General of the DHHS requesting documents in 
connection with an investigation and internal review concerning the possible 
submission of false or improper claims to, and their payments by, the 
Medicare and Medicaid programs. Other independent clinical laboratories have 
received similar subpoenas which Nichols believes are related to a nationwide 
audit and investigation of certain clinical laboratory industry practices. 
The subpoena specifically requests documents relating to 14 tests performed 
by Nichols in conjunction with a recognized group of tests known as a 
chemistry panel and paid for under these federal programs. Nichols has not 
been charged with any violation and is fully cooperating in the government's 
investigation. At this time, it is too early to predict the results of the 
investigation or its impact, if any, on Nichols' financial condition or 
results of operations. See "BUSINESS OF NICHOLS--General--OIG Investigation" 
and Note 11 to the accompanying consolidated financial statements. Nichols 
has incurred significant costs in 1993 responding to requests in connection 
with this investigation and expects these costs to increase during 1994. 

                             BUSINESS OF CORNING 

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

Corning is an international corporation competing in four broadly based 
business segments: Specialty Materials, Communications, Laboratory Services 
and Consumer Products. Corning is engaged principally in the manufacture and 
sale of products made from specialty glasses and related inorganic materials 
having special properties of chemical stability, electrical resistance, heat 
resistance, light transmission and mechanical strength. Corning and its 
subsidiaries annually produce some 60,000 different products at 44 plants in 
eight countries. In addition, Corning, through subsidiaries and affiliates, 
engages in laboratory services businesses, including life and environmental 
sciences and clinical-laboratory testing at more than 50 facilities in ten 
countries. 

Corning's strategy includes growth from new products developed from Corning's 
long-standing commitment to research and development and from mergers and 
acquisitions. Accordingly, Corning continuously reviews potential acquisition 
opportunities, primarily in the laboratory services and communications areas. 
However, there can be no assurance that Corning will pursue any such 
acquisition opportunity. 

In addition to the restructuring programs already under way, Corning is 
currently engaged in a comprehensive review of its business and cost 
structure. Corning expects this review to be substantially completed by the 
end of 1994. 

Specialty Materials. Corning's Specialty Materials segment sells more than 
40,000 products and has evolved from Corning's historical business base in 
materials development. The major business units within the Specialty 
Materials segment are: automotive substrates, ophthalmic and optical 
products, automotive lighting, science products, and other advanced 
materials. Products manufactured by these businesses include cellular 
ceramics for automotive and stationary emission-control devices, plastic and 
glass ware for laboratory applications and glass optical lenses. 

Corning's long-standing commitment to research, development and engineering 
has driven the introduction of new products and technologies. In the 1970's 
Corning developed the technology and created products for the substrates used 
in emission control systems. Today the environmental products business 
continues to be a driving force within the Specialty Materials segment. 
Corning continues to develop new products and technologies to meet increasing 
demand as a result of tightened regulations in the United States and Europe 
and new regulations in other parts of the world. For example, to meet 
tightening clean air standards, Corning has developed as a prototype an
<PAGE>
<PAGE>
 
electrically heated automotive catalytic converter substrate that begins 
working within seconds of ignition, which is when most of the pollutants are 
generated. Corning has developed a new family of materials, glass-polymers, 
the properties of which make them well suited for components in automobiles, 
aircraft, lighting systems and electronic devices. 

Corning's equity company investments in this segment include Dow Corning, 
Pittsburgh Corning Corporation and Cormetech, Inc., an equity company which 
manufactures and sells stationary emission control devices for power plants. 

Communications. Corning's Communications segment consists of the following 
major product lines: optical fiber, optical cable, optical components, 
liquid-crystal display glass, television bulbs, lenses for projection 
television, and magnetic memory disks. 

Corning's Communications segment also originates from Corning's commitment to 
research and development in new materials. Corning led the development of the 
modern opto-electronics market with its invention of optical fiber in the 
late 1960's and is the leading supplier of optical fiber and such supporting 
components as couplers and signal splitters. Corning is also a leading 
supplier of optical cable through its 50% ownership of Siecor. In addition, 
Corning has several equity investments in companies that produce optical 
fiber internationally. 

Approximately two-thirds of the revenues in the Communications segment are 
generated by sales of opto-electronic products. Today, optical fiber is 
penetrating the communications market as optical fiber is rapidly becoming 
the preferred way to transmit telephone, cable-TV and computer data 
worldwide. Optical fiber permits the transmission of substantially more data 
over greater distances with less distortion than does copper, the product it 
is principally replacing. As users of optical fiber increase applications and 
expand services, Corning continues to provide new and improved optical-fiber 
products and corollary components to an expanding market. During the next few 
years, management believes that more fiber will be deployed in distribution 
cables and that utilization of fiber to the home will increase. 

Corning continues to be a leading producer of glass panels and funnels for 
television picture tubes through Corning Asahi Video Products Company, and is 
also a world leader in the production of projection television lenses through 
its wholly owned subsidiary, U.S. Precision Lens Inc. 

The market for liquid-crystal display glass continues to grow, currently 
driven by notebook computer and portable-TV sales. Future applications are 
expected to include desktop-computer displays, projection-TV systems, video 
phones and automotive applications. Corning is the world's leading supplier 
in this market. 

Also included in this segment is Biosym Technologies Inc., which develops and 
markets computer-aided molecular design software. 

Laboratory Services. Corning entered the laboratory services market in the 
early 1970s with its initial investment in MetPath, a regional U.S. clinical 
laboratory which Corning acquired in 1982. Since 1982, Corning has made 
several other acquisitions in the clinical, biological, pharmaceutical and 
environmental-services industries. In 1991 Corning combined its 
laboratory-service business units into a wholly owned subsidiary, CLSI, to 
better manage the development of its business in this rapidly growing area. 
Today CLSI, through subsidiaries and affiliates, operates more than 50 
facilities in ten countries that provide clinical, pharmaceutical and 
environmental testing services. 

CLSI's clinical testing subsidiary, MetPath, performs more than 1,400 
different clinical tests for physicians, hospitals, laboratories, industries, 
health-maintenance organizations and other managed-care providers through a 
quick-response network of regional U.S. laboratories. MetPath is a leader in 
providing cost-effective and reliable clinical diagnostic testing services. 
See "--Recent Developments--Department of Justice Investigation." 

In August 1993, Corning acquired all of the outstanding shares of common 
stock of Damon in a transaction accounted for as a purchase. The total 
purchase price of this transaction was approximately $405 million, including 
acquisition expenses. In addition, approximately $167 million of indebtedness 
of Damon has been refinanced. Corning has financed the acquisition of Damon 
and the refinancing of Damon's debt with financing agreements entered into 
with certain commercial banks. Approximately $200 million of such financing 
was retired with the proceeds from the issuance of long-term debt of Corning. 
Corning retired the remaining acquisition debt with the net proceeds of the 
MIPS Offering. 

Damon's principal line of business is clinical-laboratory testing, providing 
to the medical profession a full range of routine and esoteric testing 
services that are used in the diagnosis, monitoring and treatment of disease.

Damon provides its services to physicians, hospitals, nursing homes, managed 
care institutions, corporations and governmental agencies, including agencies 
of the United States of America. 

On June 7, 1994, Corning acquired all of the outstanding shares of Maryland 
Medical and several affiliates for approximately 4.5 million shares of 
Corning Common Stock in a pooling-of-interests transaction. 

CLSI's pharmaceutical-testing businesses are conducted by MetPath's wholly 
owned subsidiaries, G.H. Besselaar Associates, Hazelton Corporation and 
SciCor Inc. These businesses perform chemical and biological testing, 
clinical research and data management services primarily for the 
pharmaceutical industry. Corning's environmental-laboratory testing business 
is conducted by MetPath's Enseco division and provides tests for 
environmental contaminants in soil, water and air for industry and 
government. On June 28, 1994, Corning and International Technology 
Corporation created a jointly owned company to provide environmental testing 
and related services, to which Corning transferred the net assets of 
MetPath's environmental testing laboratory business, and International 
Technology Corporation transferred the assets of its IT Analytical Services 
business. Corning and International Technology Corporation each own 50 
percent of the new company. See "-- Recent Developments--Creation of 
Environmental Testing Services Company." 

Corning's Laboratory Services segment is being affected by new federal 
legislation implemented in January 1994. The new legislation reduces Medicare 
reimbursement rates and will limit future laboratory fee increases. In 
addition, the Clinton Administration's health-care plan calls for managed 
competition with limitations on total national health-care expenditures and 
on the annual growth of such expenditures. A health-care reform model based 
on managed competition will likely reduce reimbursements for clinical 
laboratory services as managed care networks continue to proliferate. As the 
plan also calls for insurance coverage for some 37 million people who 
currently have no such coverage, it is expected that demand for such services 
will increase. Demand should also increase as a result of a stronger emphasis 
on testing as a preventative measure. It is not clear how quickly or to what 
extent Medicare and Medicaid programs will be incorporated into the health 
reform system. Management believes that while the entire health-care industry 
faces dramatic challenges to build a more effective means of delivery of 
services, MetPath's leading market position in major geographic areas will 
allow Corning to continue to benefit from the ongoing and increasing 
consolidation in the industry. 

Consumer Products. Corning is well known for its line of consumer housewares 
with strong brand names and consumer franchise. Key product lines are 
Pyrex((r)) glassware, Corelle((r)) tableware, Corning Ware((r)), Visions((r)) 
cookware, and Revere Ware((r)) cookware. Other Corning consumer products 
include the prestigious Steuben((r)) crystal and Serengeti((r)) sunglasses. 

Corning's executive offices are located at One Riverfront Plaza, Corning, New 
York 14831, and its telephone number at such offices is (607) 974-9000. 

Recent Developments 
Disposition of Clinical Laboratory Testing Operations. On April 4, 1994, 
MetPath sold the clinical laboratory testing operations of Damon in 
California for approximately $51 million in cash. No gain or loss will be 
recognized as a result of this transaction. The proceeds from the transaction 
were used to retire a portion of the debt incurred in connection with the 
acquisition of Damon in August 1993. 

Creation of Environmental Testing Services Company. On June 28, 1994, Corning 
and International Technology Corporation created a jointly owned company to 
provide environmental testing and related services, to which Corning 
transferred the net assets of its environmental testing laboratory business 
and International Technology Corporation transferred the assets of its IT 
Analytical Services business. Corning and International Technology 
Corporation each own 50 percent of the company. Corning will account for its 
investment in the newly created company using the equity method of accounting 
for investments. The impact of the transaction is not expected to be material 
to Corning's financial statements. 

Acquisition of Clinical Laboratory Testing Businesses. On June 7, 1994, 
Corning acquired all of the outstanding shares of Maryland Medical for 
approximately 4.5 million Corning Common Shares in a pooling of interests 
transaction. 

Corning's consolidated financial statements for periods prior to the Nichols 
and Maryland Medical transactions will not be restated since the acquisitions 
are not material to Corning's financial position or results of operations. 
Corning will likely record a one-time charge of up to $10 million after-tax 
in the third quarter for transaction costs associated with these acquisitions 
and may possibly record an additional one-time charge of up to $25 million 
after-tax in the second half of 1994 for the integration of the Nichols and 
Maryland Medical operations into MetPath.
<PAGE>
<PAGE>
 
Sale of Parkersburg Plant. In May 1994, Corning sold its Parkersburg, W. Va., 
glass-tubing products plant to Schott Scientific Glass, Inc., a subsidiary of 
the Schott Group, for $57 million and decided to exit several minor product 
lines in the specialty materials segment. The net gain from these 
transactions is not material. 

MIPS Offering. On July 21, 1994, Corning and Corning Delaware, a Delaware 
special purpose limited partnership in which Corning is the sole general 
partner, completed the MIPS Offering of $373.8 million aggregate principal 
amount of Preferred Securities. 

Dividends on the Preferred Securities will be cumulative and will be payable 
monthly at an annual rate of six percent. In certain circumstances, holders 
of the Preferred Securities, voting as a class or by written consent, may 
cause the exchange of the Preferred Securities for shares of Corning's Series 
C Convertible Preferred Stock, par value $100 per share ("Series C Preferred 
Stock"), at a rate of one share of Series C Preferred Stock for every two 
Preferred Securities. Each Preferred Security is convertible at the option of 
the holder into Corning Common Shares at the rate of 1.2821 shares of Corning 
Common Stock for each Preferred Security (equivalent to a conversion price of 
$39.00 per share of Corning Common Stock), subject to adjustment in certain 
circumstances. From time to time after four years from the date of issuance, 
the Preferred Securities will be redeemable, at the option of Corning 
Delaware, in whole or in part, for cash at stated redemption prices. The 
Preferred Securities are subject to mandatory redemption on the 30th 
anniversary of the date of original issuance at a redemption price of $50 per 
Preferred Security together with accumulated and unpaid dividends (whether or 
not earned or declared). Holders of the Preferred Securities do not have any 
voting rights, except in certain instances of default. 

The Series C Preferred Stock will have dividend, conversion, optional 
redemption, and other terms substantially similar to the terms of the 
Preferred Securities, except that, among other things, the Series C Preferred 
Stock will not be subject to mandatory redemption. See "DESCRIPTION OF 
CORNING CAPITAL STOCK--Series C Preferred Stock." 

The proceeds received from the MIPS Offering were used by Corning to retire 
the debt incurred to acquire Damon, as described under "CORNING UNAUDITED PRO 
FORMA COMBINED FINANCIAL INFORMATION." 

Breast Implant Litigation. Corning continues to be a defendant in two types 
of cases previously reported involving the silicone-gel breast implant 
products or materials formerly manufactured or supplied by Dow Corning or a 
Dow Corning subsidiary. These cases include (1) several purported federal 
securities class action lawsuits and shareholder derivative lawsuits filed 
against Corning by shareholders of Corning alleging, among other things, 
misrepresentations and omissions of material facts, breach of duty to 
shareholders and waste of corporate assets relative to the silicone-gel 
breast implant business conducted by Dow Corning and (2) as of May 23, 1994 
over 3,490 lawsuits filed in various state courts against Corning and others 
(including Dow Corning) by persons claiming injury from the silicone-gel 
breast implant products or materials formerly manufactured by Dow Corning or 
a Dow Corning subsidiary. Several of such suits have been styled as class 
actions and others involve multiple plaintiffs. 

All of the more than 3,000 tort lawsuits filed against Corning in federal 
courts were consolidated in the United States District Court, Northern 
District of Alabama, and in early December 1993, Corning was dismissed from 
these cases. This decision by the District Court is non-appealable and, 
although the District Court noted that it was "highly unlikely" that 
additional discovery would produce new evidence, the decision is subject to 
reconsideration if additional information is discovered or if there is a 
change in state law. Certain state court tort cases against Corning have also 
been consolidated for the purposes of discovery and pretrial matters. During 
1994, Corning has made several motions for summary judgment in state courts 
and judges have dismissed Corning from all of the over 2,500 tort cases filed 
in California, Michigan, New York and Pennsylvania, some of which are on 
appeal. Corning's motions seeking dismissal remain pending in various other 
states. The federal securities suits are all pending in the United States 
District Court for the Southern District of New York. 

Corning's management does not believe that the purported securities class 
action lawsuits or the purported shareholder derivative lawsuits or the tort 
actions filed against Corning described above will have a material adverse 
effect on Corning's financial condition or the results of its operations. 

Dow Corning has informed Corning that as of July 8, 1994, Dow Corning has 
been named in 45 purported breast implant product liability class action 
lawsuits and approximately 15,900 individual breast implant product liability 
lawsuits (which number includes all or substantially all of the 3,490 
lawsuits referred to above) and that Dow Corning anticipates that it will be 
named as a defendant in additional breast implant lawsuits in the future. Dow 
Corning has also stated that it is vigorously defending this litigation. 

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

In March 1994, Dow Corning, along with other defendants and representatives 
of breast implant litigation plaintiffs, signed a Breast Implant Litigation 
Settlement Agreement (the "Settlement Agreement"). The Settlement Agreement 
is subject to court approval and to withdrawal by Dow Corning and other 
defendants and plaintiffs. Under the Settlement Agreement and related 
agreements, industry participants (the "Funding Participants") would 
contribute approximately $4.2 billion over a period of more than thirty years 
to establish several special purpose funds. The Settlement Agreement, if 
implemented, would provide for a claims based structured resolution of claims 
arising out of silicone breast implants, define the circumstances under which 
payments from the funds would be made and include a number of other 
provisions related to claims and administration. The Settlement Agreement 
defines periods during which breast implant plaintiffs may elect not to 
settle their claims by way of the Settlement Agreement and to continue their 
individual breast implant litigation against manufacturers and other 
defendants (the "Opt Out Plaintiffs"). In certain circumstances, if Dow 
Corning considers the number of Opt Out Plaintiffs to be excessive, Dow 
Corning is entitled to withdraw from participation in the Settlement 
Agreement. Corning is not a party to the Settlement Agreement and will not 
make any contribution to the settlement contemplated thereby. 

In April 1994, the United States District Court for the Northern District of 
Alabama preliminarily approved the Settlement Agreement and temporarily 
stayed and suspended federal and state class action certification or notice 
proceedings relative to federal or state class action lawsuits filed by 
plaintiffs included in the settlement class. 

In April 1994, the Court also notified the breast implant plaintiffs eligible 
to participate in the settlement of a 60-day period during which they have 
the ability to become initial Opt Out Plaintiffs. Unless the current schedule 
is extended by the Court, Dow Corning would expect to decide whether or not 
to exercise its option to withdraw from the Settlement Agreement by 
mid-August 1994. A Court-supervised fairness review process of the Settlement 
Agreement must be completed before the Settlement Agreement can be 
implemented. Once the Settlement Agreement is approved by the Court, claims 
can then be validated. The Court's approval of the Settlement Agreement would 
be subject to appeal. 

Dow Corning recorded a pre-tax charge of $640 million ($415 million after 
tax) against its earnings for the fourth quarter of 1993 to reflect its best 
estimate as of January 1994 of the net present value of its net liabilities 
and costs as a result of its involvement in breast implant litigation and, as 
a result of Dow Corning's decision to take this charge, Corning recorded a 
charge of $203 million after tax against its equity in earnings of associated 
companies for the fourth quarter of 1993 and against the carrying value of 
its investment in Dow Corning at the end of fiscal 1993. 

If the tort actions filed against Dow Corning or any settlement of the breast 
implant controversy should require Dow Corning to record any additional 
charges against income, the effect on Corning of any such additional charges 
would be limited to their consequent impact (in the amount of approximately 
50% of the amount thereof) on Corning's reported equity in earnings of 
associated companies for the period such charges were recognized, on the book 
value of Corning's equity investment in Dow Corning and on Corning's retained 
earnings. Corning does not believe that its share of any additional charges 
taken by Dow Corning resulting from the breast implant controversy will have 
a material adverse effect upon Corning's financial condition. However, it is 
possible that Corning's share of any such additional charges taken by Dow 
Corning could have a material adverse effect upon Corning's earnings in the 
quarters in which any such charges were recognized by Dow Corning.
<PAGE>
<PAGE>
 
Other Dow Corning Matters. Dow Corning received a request dated July 9, 1993 
from the Boston Regional Office of the Commission for certain documents and 
information related to silicone breast implants. The request stated that the 
Boston Regional Office was conducting an informal investigation which 
"concerns Dow Corning, its subsidiary Dow Corning Wright and parent 
corporations, Dow Chemical Co. and Corning Inc." Dow Corning has informed 
Corning that Dow Corning has responded to this request enclosing the 
documents and information requested along with related information and 
continues to cooperate with the Boston Regional Office. 

During the first quarter of 1993, Dow Corning received two federal grand jury 
subpoenas initiated by the United States Department of Justice ("DOJ") 
seeking documents and information related to silicone breast implants. Dow 
Corning has informed Corning that it has delivered the documents and 
information requested and continues to cooperate with the DOJ as this grand 
jury investigation proceeds. 

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

On July 21,1994, Moody's Investors Service downgraded the senior long-term 
debt ratings on Dow Corning's debentures, industrial revenue bonds, and 
medium-term notes to Ba1 from Baa1. Dow Corning's commercial paper rating was 
also downgraded to Not-Prime from Prime-2. Moody's stated that this action 
reflects its view of the increased risk facing Dow Corning in view "of the 
unexpectedly large number of opt-outs from the proposed global settlement of 
silicone breast implant litigation." 

Department of Justice Investigations. In September 1993, MetPath and MetWest 
Inc. ("MetWest"), a wholly owned subsidiary of Unilab, in which Corning had 
at the time an interest of approximately 43%, entered into a Settlement 
Agreement (the "MetPath Settlement Agreement") with the DOJ and the Inspector 
General of the Department of Health and Human Services (the "Inspector 
General"). Pursuant to the MetPath Settlement Agreement, MetPath and MetWest 
paid to the United States a total of $39.8 million in settlement of civil 
claims by the DOJ and the Inspector General that MetPath and MetWest had 
wrongfully induced physicians to order certain laboratory tests without 
realizing that such tests would be billed to Medicare at rates higher than 
those the physicians believed were applicable. 

Several state and private insurers have made claims based on the practices 
covered by the MetPath Settlement Agreement. Several have settled but it is 
not clear at this time what, if any, additional exposure Corning may have to 
these entities and to other persons who may assert claims on the basis of 
these or other practices. 

During August 1993, MetPath, MetWest and Damon (which was acquired by Corning 
in that month) together with other participants in the industry received 
subpoenas from the Inspector General seeking information regarding their 
practices with respect to 14 enumerated tests offered in conjunction with 
automatic chemical test panels. Of these 14 tests, five were covered by the 
MetPath Settlement Agreement and consequently MetPath and MetWest are not 
being required to provide further information with regard to them. MetPath, 
MetWest and Damon have completed this process of complying with these 
subpoenas. Metpath also received in May 1994 two subpoenas from the Inspector 
General concerning, in one case, an investigation into billings for tests not 
performed or reported for which MetPath had voluntarily made corrective 
payments in 1993 and, in the other, an investigation into whether separate 
billings for tests which should have been grouped together had occurred. In 
addition, a federal grand jury in New Jersey is investigating the billings 
for tests not performed or reported. The results of these investigations 
cannot currently be predicted but the possibility that they may result in 
additional claims by the DOJ or the Inspector General or additional claims or 
settlements with parties other than the DOJ and the Inspector General cannot 
be excluded. 

Other Legal Proceedings. During September 1993, two individuals filed in the 
Supreme Court of the State of New York (one in New York County and one in 
Suffolk County) separate purported derivative actions against Corning, as 
nominal defendant, and Corning's Directors and certain of its officers 
seeking on behalf of Corning compensatory and punitive damages in unspecified 
amounts (and plaintiffs' costs and disbursements including attorneys' and 
experts' fees) by reason of the alleged responsibility of the actual 
defendants for the conduct which gave rise to the settlement in the MetPath 
litigation described above and their alleged failure to cause Corning to make 
timely disclosure thereof. The parties have agreed to consolidate such 
actions in a single action before the Supreme Court of the State of New York 
in New York County. 

During October 1993, two individuals instituted in the United States District 
Court for the Southern District of New York separate purported class actions 
on behalf of purchasers of Corning securities in the open market during
<PAGE>
<PAGE>
 
the period from September 17 to October 6, 1993 against Corning, certain of 
its Directors and officers and the underwriters of Corning's offering, on 
September 17, 1993, of $100 million of 6.75% Debentures due on September 15, 
2013. The complaints generally allege that the defendants failed to make 
timely disclosures of adverse developments in Corning's business and seek 
compensatory and punitive damages in unspecified amounts (and plaintiffs' 
costs and expenses including attorneys' fees and disbursements). These two 
actions, with respect to which the underwriters have been dismissed, have 
been consolidated. 

Two class actions have been filed in the Court of Chancery for the State of 
Delaware against Damon and certain of its officers and directors. These suits 
allege damages arising from Damon's failure to mention in the press release 
that announced the initial merger agreement it had reached with a company 
other than Corning that an unnamed bidder (Corning) had also expressed 
interest in acquiring Damon. The class of plaintiffs are those who sold their 
stock at the price offered by the other company, rather than the higher 
amount later offered and paid by Corning. 

Corning's management does not believe that the purported class action 
lawsuits or the purported shareholder derivative lawsuits described above 
will have a material adverse effect on Corning's financial condition or the 
results of its operations. 

                             BUSINESS OF NICHOLS 

General 
Nichols provides clinical testing services to hospitals, laboratories and 
physicians on a nationwide basis through the Reference Laboratories, the 
Regional Laboratories, Diagnostics and its substance abuse testing laboratory 
("NISAT"). Nichols offers a comprehensive line of tests consisting of over 
1,100 tests or "assays," substantially all of which are performed in Nichols' 
facilities. These tests are used principally as aids in the diagnosis and 
treatment of a wide variety of medical conditions such as cancer, AIDS, 
endocrine disorders, cardiac disorders and genetic diseases. 

Nichols was incorporated in 1981 for the purpose of combining the businesses 
of Nichols Institute Reference Laboratories, incorporated in 1971, and 
Nichols Institute Diagnostics, incorporated in 1974, under a single holding 
company. Nichols acquired its Regional Laboratories between 1985 and 1991 and 
organized NISAT in 1988. Nichols' corporate headquarters and its Reference 
Laboratories are located in San Juan Capistrano (Orange County), California. 

Nichols has historically incurred substantial losses relative to its Dallas 
operations and more recently its other Texas operations. During 1991 and 1992 
Nichols incurred substantial losses relative to its Dallas operations and 
recorded restructuring charges of $0.9 million and $13.0 million, 
respectively. The restructuring of the Dallas operations was largely 
completed as of September 1993. Nichols' remaining Texas operations, all 
acquired in 1991, did not perform to expectations and in late 1992 and 
continuing into 1993 incurred substantial losses. In the fourth quarter of 
1993, Nichols recognized restructuring and unusual charges totaling $16.0 
million, including $7.5 million related to further consolidation and 
downsizing of its Texas operations. See "NICHOLS MANAGEMENT DISCUSSION AND 
ANALYSIS--Results of Operations--Restructuring and unusual charges--1991, 
1992, and 1993" for further discussion. 

The results of operations in the fourth quarter of 1993, before restructuring 
and unusual charges, were not sufficient to meet certain financial covenants 
under Nichols' senior notes aggregating $62.2 million as of March 31, 1994. 
The senior note agreements provide that, as a result of the failure to comply 
with those covenants, the holders of the senior notes have had the right 
since December 31, 1993 to declare the entire unpaid balance immediately due 
and payable. If that were to occur, Nichols would not have the funds required 
to retire the debt unless alternative financing is obtained. Pursuant to the 
terms of the Merger Agreement, Corning has agreed to repay, or cause the 
Surviving Corporation to repay, the Senior Notes. Additionally, due to the 
results of operations in the fourth quarter of 1993, Nichols' $15.0 million 
bank line of credit was terminated. While there were no borrowings 
outstanding under the line of credit and none had been outstanding since 
April 1993, if the Merger is not consummated, Nichols considers the 
availability of a bank line of credit to be prudent in order to insure its 
ability to satisfy its working capital needs and meet other short-term 
obligations. No assurance can be given that such alternative financing will 
be obtained. 

The Clinical Laboratory Industry 
Clinical laboratory tests are used by physicians to diagnose, monitor and 
treat diseases and other medical conditions through the detection of 
substances and abnormalities in blood and/or tissue samples and other 
specimens. Clinical laboratory tests are primarily performed by hospitals 
in-house, by physicians in their offices, by physician-owned laboratories or 
by independent laboratories. Nichols views the clinical laboratory industry 
as highly fragmented with many local and regional competitors.
<PAGE>
<PAGE>
 
Of the approximately 4,000 independent laboratories in the clinical 
laboratory industry, the vast majority are local or regional in scope and 
perform routine, less sophisticated tests rather than the esoteric tests from 
which Nichols derives a substantial portion of its revenues. The complexity 
and sophistication of esoteric tests generally require expensive equipment 
and materials as well as skilled personnel to perform test procedures and 
analyze results. Consequently, esoteric tests are generally priced higher 
than routine tests. The volume of esoteric tests required by most hospitals, 
physicians and other healthcare providers is relatively low compared to the 
volume of routine tests. Because it is generally not cost effective for these 
healthcare providers to perform the low volume of esoteric tests in-house, a 
significant portion of esoteric tests are referred to independent clinical 
laboratories. 

Nichols believes that the clinical laboratory industry has and continues to 
experience pressures on revenues as healthcare providers respond to the 
industry trend toward increased use of managed care programs, fewer test 
requisitions per patient and increased governmental regulation. Nichols 
believes that these pressures on revenues will continue in the future. 
Additionally, continued changes in healthcare reimbursement policies of the 
federal government, additional cost containment measures of private insurers 
and upward pressure on costs due to increased sophistication of tests are 
creating an incentive for hospitals and other healthcare providers to 
consolidate laboratory operations through joint ventures or other contractual 
arrangements with independent clinical laboratories. However, Nichols 
believes that factors such as heightened public concern about health, the 
aging of the population, the increased use of preventative screening tests 
and scientific advances that have made a greater variety of tests available 
will sustain the demand for diagnostic testing. 

During recent years, the clinical laboratory industry has experienced 
substantial consolidation. Nichols believes that this consolidation will 
continue because of existing overcapacity in the industry and the cost burden 
on many small laboratories of regulatory requirements with respect to 
increased quality standards. See "Healthcare Reimbursement." Physician-owned 
laboratories and laboratories located in physicians' offices are expected to 
be particularly impacted by the costs required to comply with the new quality 
standards, and many of these laboratories may cease to operate or may be 
acquired by independent laboratories. 

Reference Laboratories 
Nichols' esoteric testing is conducted centrally at its Reference 
Laboratories. The Reference Laboratories are comprised of 18 individual 
laboratory departments, which, in the aggregate, offer approximately 900 
individual tests or "assays" in such fields as endocrinology, genetics, 
immunology, microbiology, nutrition-metabolism, oncology, serology and 
toxicology. The Reference Laboratories offer a comprehensive line of tests. 
The Reference Laboratories' testing procedures employ a variety of advanced 
analytical technologies, including radioimmunoassays, fluorescent 
immunoassays, chemiluminescent immunoassays, monoclonal antibodies, cell 
culture technologies and DNA probes. Nichols also supports the efforts of 
pharmaceutical and biotechnology companies in the regulatory approval process 
for new drugs through its Clinical Studies Center located within the 
Reference Laboratories. 

Nichols believes that during its 23 years of operation the Reference 
Laboratories have established a reputation in the industry as a high quality 
provider of accurate and clinically useful tests. Nichols, through its 
Reference Laboratories, its association with leading academicians (the 
"Academic Associates") and its relationship with biotechnology firms, 
believes that it is one of the leaders in transferring technological 
innovation from academic laboratories to the marketplace. Nichols was the 
first to introduce a number of esoteric tests, including immunoassay methods 
for measurement of circulating hormone levels and sensitive tests to predict 
breast cancer prognosis. Since 1984, the number of esoteric tests offered by 
Nichols has more than doubled. The growth in Nichols' testing capabilities 
can be directly attributed to its association with the Academic Associates 
through which Nichols develops new esoteric tests for commercial application. 
The Academic Associates program is involved with all phases of development of 
Nichols' tests, from identifying promising testing methodologies to 
implementing and periodically monitoring actual test procedures in Nichols' 
laboratories. See "Research and Development--Academic Associates." More 
recently, Nichols has relied to a greater degree on its internal resources 
for the development of tests, as well as license arrangements and 
co-development agreements with biotechnology companies, to provide continued 
access to new technology. Among Nichols' more significant recent developments 
are tests to detect a variety of tumor types, a common form of mental 
retardation, leukemia, cystic fibrosis, osteoporosis, diabetes and to aid in 
the diagnosis of Alzheimer's disease. 

Nichols has also committed substantial resources in order to provide 
effective customer service and rapid turnaround time for its tests. In 
addition to maintaining a national network of couriers to pick up specimens, 
Nichols has established and maintains a telecommunications network capable of 
delivering results expeditiously to personal computers or terminals in the 
customer's facility. These capabilities enable Nichols to provide certain 
esoteric tests requiring particularly rapid processing which otherwise would 
have to be performed locally or in-house. Nichols provides its clients with 
access to its highly trained client service representatives, scientific 
directors and board certified medical directors by telephone for technical 
questions regarding test results twenty-four hours a day, seven days a week.
<PAGE>
<PAGE>
 
Net revenues from Reference Laboratories tests during the years ended 
December 31, 1991, 1992 and 1993 accounted for approximately 37%, 35% and 
36%, respectively, of Nichols' consolidated net revenues for those periods. 

Regional Laboratories 
Since 1985, Nichols has acquired a number of Regional Laboratories that 
typically perform more routine, non-esoteric tests for hospitals and 
healthcare providers located in their geographic areas. Nichols' Regional 
Laboratories serve markets in California, the Pacific Northwest, the Midwest, 
Texas and Alaska. Certain of these Regional Laboratories have significant 
market presence within their localities. The Regional Laboratories allow 
Nichols to provide tests on an expedited and economical basis by reducing the 
time and expense required to transport specimens. The Regional Laboratories 
also enable Nichols to establish and maintain ties with local medical 
communities which are important in obtaining and maintaining testing business 
for these laboratories and the Reference Laboratories. Nichols estimates that 
for the year ended December 31, 1993 approximately 8% of the Reference 
Laboratories' revenues resulted directly from referrals by the Regional 
Laboratories. 

The Regional Laboratories offer a broad spectrum of routine testing services 
tailored for the particular markets in which the Regional Laboratories are 
located and are responsive to the particular needs of those markets. Such 
services include chemistry, hematology, immunology, microbiology, urinalysis, 
serology, cytology, histology, anatomic pathology and toxicology testing. The 
ability to make available these lines of tests, including the Reference 
Laboratories' esoteric tests, allows the Regional Laboratories to meet a wide 
range of testing needs. 

Acquisitions of Regional Laboratories have contributed significantly to 
Nichols' revenue growth from 1985 through 1992. Net revenues from Regional 
Laboratories for the years ended December 31, 1991, 1992 and 1993 accounted 
for 52%, 53% and 51%, respectively, of Nichols' consolidated net revenues for 
such years. 

Diagnostics 
Diagnostics manufactures and markets clinical laboratory test kits. 
Diagnostics' kits are sold to hospitals and clinical laboratories that have 
sufficient testing volume to justify the staffing, equipment and supply costs 
to perform such tests in-house. Certain of the tests currently performed in 
the Reference Laboratories are further refined, simplified and packaged so 
that they can be offered as kits to laboratory customers of Nichols. Most of 
Diagnostics' kits are targeted to niche markets in an effort to minimize 
competition from other kit manufacturers. Diagnostics distributes its 
products in many countries throughout the world, with most of its sales 
occurring in the United States, Europe and Japan. 

Diagnostics' product line consists of 28 radioimmunoassay (isotopic) test 
kits and 17 chemiluminescence (non-isotopic) test kits. The test kits yield 
results which can be correlated with the results of tests performed by the 
Reference Laboratories. Nichols believes that its correlation data, which is 
useful in interpreting test results, is an important marketing tool that 
distinguishes its kits from those of many of its competitors. 

During the past three years Nichols has made two acquisitions which have 
enhanced Diagnostics' technological base. In 1991 Nichols acquired Immuno 
Technology Services, a small Dutch company engaged in the development, 
production and distribution of radioimmunoassay test kits similar to those of 
Nichols. During 1992 Nichols acquired London Diagnostics, Inc., a Minnesota 
company that manufactured and distributed diagnostic test kits and developed 
direct chemiluminescence, a non-isotopic technology. In the past five years, 
as a result of regulatory and environmental considerations, the diagnostics 
test kit industry has been transitioning from radioisotope technology toward 
the use of non-isotopic methods. The acquisition of London Diagnostics, Inc. 
has allowed Diagnostics to participate effectively in this change and to 
maintain Diagnostics' growth momentum. Seventeen new products based on 
chemiluminescence have been developed and introduced to the marketplace since 
May 1992. Nichols has incorporated this non-isotopic technology into its line 
of diagnostic test kits, which is being used with semi-automated 
instrumentation. Nichols is considering development of fully automated 
instrumentation which will allow the processing of patient specimens without 
significant labor expense and would enhance the benefits of this technology. 
Development of the fully automated instrumentation would require Nichols to 
commit substantial financial resources and to obtain financing to fulfill the 
capital requirements. Nichols currently has no formal plan to develop or fund 
such fully automated instrumentation. 

Net revenues from Diagnostics, including the revenues recognized under its 
contracted research and development and licensing arrangement (see "Other 
Contracted Research and Development"), accounted for approximately 8%, 9% and 
10% of Nichols' consolidated net revenue during the years 1991, 1992 and 
1993, respectively. 

NISAT 
Nichols began substance abuse testing in 1985, and in 1988 organized NISAT to 
own and operate its substance abuse testing laboratory. Certain employees of 
governmental agencies, as well as regulated industries such as trans
<PAGE>
<PAGE>
 
portation and nuclear power, are subject to mandatory pre-employment and 
continuing random testing. NISAT, located in San Diego, California, was one 
of the first substance abuse laboratories in the United States to be 
certified by the National Institute on Drug Abuse, a division of the 
Department of Health and Human Services ("DHHS"). Today there are nearly 100 
DHHS-certified laboratories, which include most of Nichols' principal 
competitors. However, Nichols' national courier system enhances its ability 
to process samples rapidly, providing Nichols with an important sales 
advantage in today's competitive workplace drug testing market. 

Net revenues from substance abuse tests performed by NISAT accounted for 
approximately 3% of Nichols' consolidated net revenues during each of the 
years 1991, 1992 and 1993. 

Sales and Marketing 
Nichols directs its marketing efforts primarily to physicians, hospital 
pathologists, laboratory managers and hospital administrators. Nichols 
maintains dedicated and distinct sales and marketing organizations for the 
Reference Laboratories, the Regional Laboratories, Diagnostics and NISAT. 

The Reference Laboratories' sales and marketing efforts are coordinated 
through regional sales and service offices located in the New Jersey, 
Chicago, Atlanta, Dallas-Ft. Worth, Oakland and Los Angeles metropolitan 
areas. Nichols believes that one of the factors distinguishing it from its 
competitors is the advanced technical and clinical knowledge of the Reference 
Laboratories sales staff. Each Reference Laboratories sales representative 
receives extensive training, including participation in seminars and 
workshops, which provides the sales representative with detailed knowledge of 
the accuracy and clinical efficacy of Nichols' tests. 

The Regional Laboratories and NISAT employ their own direct sales forces. In 
addition, Diagnostics' test kits are marketed by direct sales staff 
throughout the United States, the United Kingdom, Germany, The Netherlands 
and Switzerland and by independent distributors in other international 
markets. 

Nichols' ability to perform both esoteric tests through the Reference 
Laboratories and more routine tests through its Regional Laboratories results 
in intracompany test referrals and allows each sales force to market Nichols 
as a full service clinical testing laboratory that can meet a customer's 
complete testing needs. 

Nichols' Academic Associates, scientific directors and medical directors also 
play an active role in marketing Nichols' products and services, both 
directly and indirectly, through their research activities, contributions to 
scientific articles for leading medical journals, participation in medical 
and clinical testing seminars and regular speeches to professional 
organizations. This active participation by persons associated with Nichols 
in the academic and medical community enhances Nichols' reputation as a 
provider of quality test services and as a leader in clinical testing 
technology. See "Research and Development--Academic Associates." Nichols' 
marketing activities also include national advertising in medical journals, 
participation in trade shows and distribution of sales materials at national 
and regional conferences, and seminars conducted by Nichols' technical staff. 

Customer Service 
Nichols believes that providing effective customer service is an important 
element in maintaining its reputation for quality testing and in increasing 
its market share across all lines of its business. To transport the thousands 
of test specimens submitted to the laboratories each day, Nichols has 
established and maintains a network of couriers which picks up specimens 
daily from customers and ships them by air freight or ground transportation 
to Nichols' laboratories. Nichols' couriers receive training regarding the 
types of tests performed in the laboratories and the proper handling and 
transportation of test specimens. 

Test results are delivered to customers by Nichols' telecommunications 
network, by courier or by overnight delivery. Nichols has developed a system 
internally that permits the Reference Laboratories' customers to receive test 
results expeditiously via personal computers or terminals linked to Nichols' 
own computer system. Nichols also maintains a network through which results 
are telecommunicated to regional centers operated by Nichols and then 
delivered to the customer by courier. Similarly, each of the Regional 
Laboratories has a computerized system to report test results to customers. 

Nichols' computer systems also monitor the testing process and the status of 
individual specimens; such information being available to answer client 
inquiries. To facilitate those inquiries, Nichols provides access to highly 
trained client service representatives, scientific directors and 
board-certified medical directors 24 hours a day, seven days a week. In 
addition, Nichols' Academic Associates are available to consult with clients 
when appropriate. Nichols has invested significant resources to increase 
laboratory and sales staffing, purchase additional equipment and expand its 
computerization of test results and other information provided to customers. 
Nichols anticipates that it will continue to invest significant resources in 
the future to further enhance and integrate its various laboratory, 
communications and financial information systems.

Research and Development 
Nichols believes that an active research and development program is essential 
to its success in the esoteric clinical testing industry. As part of its 
research and development efforts, Nichols believes that its relationship with 
the academic community through its Academic Associates program is unique in 
the clinical laboratory industry. At any one time, there are 40 to 50 
academic scientists and six to ten biotechnology firms involved with the 
Reference Laboratories' scientific staff. Under this program, the Academic 
Associates and collaborating scientists work directly with the Reference 
Laboratories' staff scientists to monitor existing test procedures and 
develop new esoteric test methods. The activities of the Academic Associates 
are monitored and directed by Nichols' Chief Science Officer. 

Nichols' total direct research and development expenditures, excluding fees 
and royalties for Academic Associates, amounted to $3.0 million, $5.0 million 
and $4.2 million during the years ended December 31, 1991, 1992 and 1993, 
respectively. Research and development expenditures for 1992 and 1993 include 
$2.0 million and $0.3 million, respectively, expended under a contracted 
research and development arrangement with a third party distributor which was 
completed during 1993. 

Academic Associates. Nichols licenses the right to use certain tests 
developed by Academic Associates and their universities, by biotechnology 
firms or by Nichols in conjunction with Academic Associates. In some cases, 
the basic technology developed by the Academic Associates has been funded by 
government agencies or state-owned universities. As a result, the government 
agency or university involved has the right to require that rights to the 
technology be licensed to another person or entity if the agency determines, 
among other things, that action has not been taken within a reasonable time 
to achieve practical application of the technology. Universities are placing 
increasing emphasis on realizing income from the commercial applications of 
technology developed by their employees and Nichols faces increasing 
competition in acquiring technology from universities and biotechnology 
firms, whether through the Academic Associates program or otherwise. 

The arrangements with Academic Associates and biotechnology firms involve 
written contracts, some of which are with the institutions employing Academic 
Associates. Academic Associates contracts generally have two to five year 
terms, are renewable and are terminable by either party upon 180 days' 
notice. The arrangements typically provide for compensation on the basis of a 
fixed fee or a percentage of test revenue (with a minimum fee in many cases). 
Academic Associate fees and royalties amounted to $3.0 million, $2.5 million 
and $2.8 million for the years ended December 31, 1991, 1992 and 1993, 
respectively. 

Research and Development Partnerships.  Nichols' early diagnostic kit 
research and development efforts were funded through research and development 
partnerships, and focused on the development of diagnostic test kits for 
specialized market niches using technologies not easily duplicated by 
competitors. However, Nichols currently does not have any arrangements with 
research and development partnerships to fund kit research and instead is 
financing such research largely with internally-generated funds or other 
contracted research. Royalties paid pursuant to research and development 
partnerships amounted to $1.4 million, $1.0 million and $0.9 million during 
the year ended December 31, 1991, 1992 and 1993, respectively. 

Other Contracted Research and Development.  In connection with the 
acquisition of London Diagnostics, Inc. Nichols entered into an arrangement 
with an independent distributor pursuant to which the distributor provided a 
portion of the funding to develop certain medical diagnostic kits utilizing 
chemiluminescent technology. Revenues from the arrangement were recognized on 
the percentage of completion basis. During 1992 and 1993 revenues of 
approximately $1.1 million and $0.7 million, respectively, were recognized. 
No such revenues are expected in 1994. Research and development costs 
expended under the arrangement amounted to $2.0 million during 1992 and $0.3 
million during 1993. Under the arrangement Nichols owns all of the rights to 
the diagnostic kits developed, and the distributor has the right to purchase 
the kits from Nichols, manufacture the kits in conjunction with Nichols, and 
market in the Far East any such kits purchased, manufactured or developed. 
Under a separate licensing agreement, the distributor was granted rights to 
the remaining technology which enabled it to manufacture the kits on a 
stand-alone basis. During 1992 and 1993 Nichols received $0.6 million and 
$1.0 million, respectively, as a license fee, which was recognized as revenue 
when received. 

Quality Assurance 
Nichols maintains a quality assurance program for its clinical testing which 
includes control testing and regular review of test data by Company medical 
personnel and Academic Associates. Test results which fall significantly 
outside the normal range for such tests are reviewed and often repeated to 
help assure accuracy. 

The Academic Associates and Nichols' laboratory scientific staff are 
continually involved in the review and improvement of test performance and 
efficiency. Nichols encourages its scientific directors to participate in 
scientific
<PAGE>
<PAGE>
 
meetings and seminars and to present papers, often in conjunction with 
Academic Associates. Nichols believes that such active participation in 
academic and scientific programs furthers its reputation as a provider of 
high-quality clinical laboratory testing. 

Nichols also participates in or is subject to various quality control 
programs and regulations. Nichols' laboratories are accredited by the College 
of American Pathologists, certified by Medicare and Medicaid, accredited by 
the Joint Commission on Accreditation of Healthcare Organizations and 
licensed by state regulatory authorities. See "Government Regulation" and 
"Legal Proceedings." 

Competition 
Nichols faces competition from numerous commercial, hospital, university and 
physician laboratories and test kit manufacturers. In general, the clinical 
laboratory industry is highly fragmented and is consolidating, with national 
testing laboratories accounting for only a small percentage of the total 
clinical tests performed. In addition, many of Nichols' competitors are 
larger than Nichols and have substantially greater financial resources. 
Several of Diagnostics' competitors offer a broader range of diagnostic test 
kits or offer more fully mechanized systems for the processing of patient 
specimens than Nichols and may, therefore, have a competitive advantage with 
customers who prefer to deal with a single supplier for all of their test kit 
needs. Nichols is considering development of fully automated instrumentation 
which will allow the processing of patient specimens that would significantly 
enhance the benefits of this techology without significant incremental labor 
expense. Development of the fully automated instrumentation would require 
Nichols to commit substantial financial resources and to obtain financing to 
fulfill the capital requirements. However, Nichols currently has no formal 
plan to develop or fund such fully automated instrumentation. 

Nichols believes that it competes on the basis of quality, service, accuracy, 
consistency, rapid turnaround and reporting of test results, the technical 
and clinical training of its sales force, and the availability of extensive 
clinical correlation data and follow-up consultation with medical and 
technical experts. Nichols believes that Diagnostics competes on the basis of 
quality, ease of usage of the kits and, to a lesser extent, price. Nichols 
markets primarily to competitive pricing and frequently finds it necessary to 
adjust its prices in response to price-cutting practices of clinical 
laboratory competitors. However, with respect to the testing performed by the 
Reference Laboratories, in some cases its prices exceed those of its 
competitors. Nichols believes the tests performed by the Reference 
Laboratories are differentiated from those of its competitors on the basis of 
quality and clinical correlations. 

Because Nichols has not yet fully standardized and integrated Company-wide 
operating and administrative activities, particularly those of its acquired 
businesses, it has not yet realized many of the operating economies, and thus 
lower unit costs, enjoyed by many of its competitors. While Nichols ensures a 
competitive market position through pricing largely to incremental cost and 
market prices, margins have historically suffered. Although Nichols is in the 
process of and plans, ultimately, to standardize and integrate its 
operations, this process will require substantial resources and at least two 
to three years to complete. 

The clinical testing industry is characterized by rapid technological change 
and a general absence of patent protection. Although Nichols' tests are not 
dependent on any one technology, new technologies developed by competitors 
could make certain tests offered by Nichols less competitive. 

Healthcare Reimbursement 
Under law and regulation, for most of the tests performed for Medicare or 
Medicaid beneficiaries, Nichols must accept reimbursement from Medicare or 
Medicaid as payment in full. In 1984 Congress adopted legislation 
establishing a fee schedule reimbursement methodology for testing for 
out-patients under Medicare. Additionally, consumer price index adjustments 
to fee schedule payments for outpatient clinical diagnostic laboratory 
services have in the past been canceled by Congress or largely offset by 
reductions in national ceilings on fee schedule payments. For each of 1991, 
1992 and 1993, Congress set the consumer price index update for laboratory 
fee schedules at 2%. However, the national ceiling was reduced from 100% to 
93% of the national median price of tests for 1990. For 1991 through 1993, 
the ceiling was reduced to 88% of the national median. In 1994, the national 
ceiling will drop to 84% of the national median price of tests and will 
further decline in 1995 and 1996 to 80% and 76%, respectively. In addition, 
the consumer price index update has been eliminated for 1994 and 1995. Net 
revenues recorded from direct billings under the Medicare and Medicaid 
programs during the years ended December 31, 1991, 1992 and 1993, after 
deducting contractual allowances, were $27.3 million, $37.3 million and $37.2 
million, respectively, or 12%, 13% and 13% of total consolidated net 
revenues, respectively. 

Nichols' hospital clients who participate in the Medicare program are 
reimbursed for most services (including laboratory testing) provided to 
inpatients on the basis of diagnosis related groups ("DRGs"). Under this 
system, hospitals are generally paid only a fixed DRG amount per patient plus 
additional amounts for certain specific hospital
<PAGE>
<PAGE>
 
costs. The DRG amount paid for a particular patient depends on many factors, 
including the principal diagnosis of the patient, but is usually independent 
of the hospital's actual cost of treating the patient. As a result, hospitals 
generally benefit from reductions in the cost of tests provided to their 
patients. Hospitals generally are required to bill Medicare and Medicaid 
directly for outpatient diagnostic testing services. Because Nichols does not 
directly bill Medicare and Medicaid for most testing services it provides to 
hospitals and certain clinical laboratories, the actual percentages of 
Nichols' testing revenues originating from patients who participate in the 
Medicare and Medicaid programs may significantly exceed the amounts indicated 
above. 

Recent press reports indicate that HCFA is planning to establish national 
guidelines for certain tests which it believes are being improperly ordered 
as a result of being combined with a recognized group of tests known as 
chemistry panels. Such reports also indicate that HCFA is developing a 
computer program which will initially deny reimbursement for these tests when 
there is a high incidence of their being ordered in conjunction with 
automated chemistry panels, as opposed to being ordered individually. The 
burden would then shift to the clinical laboratory to show that the tests 
were medically necessary in order to receive reimbursement. 

HCFA has also indicated that it intends to begin denying reimbursement for 
certain medical diagnostic tests ordered in connection with chemistry panels 
unless certain conditions are satisfied. Nichols does not know how many tests 
will be affected by HCFA's new reimbursement policy and therefore, at this 
time, is unable to determine the extent of the impact, if any, on Nichols' 
future revenues. See "NICHOLS MANAGEMENT DISCUSSION AND ANALYSIS." 

As a result of the changes in the healthcare reimbursement policies of the 
federal government, additional cost containment measures of private insurers, 
increasing competition in the healthcare industry and upward pressure on 
costs resulting from increased sophistication of tests, hospitals, health 
maintenance organizations, and other healthcare providers are under 
continuing pressure to find ways to reduce the costs of delivering healthcare 
services. Nichols believes that the industry has responded, and will continue 
to respond, through consolidation and development of healthcare alliances. 
Where economically feasible, these consolidated entities and alliance groups 
are handling their testing needs in-house. Healthcare providers have also 
responded to the need to control costs by ordering fewer tests. In addition, 
any reduction in tests performed by hospital laboratories may adversely 
affect sales of Diagnostics' test kits. Nichols does not know the extent to 
which it has been adversely affected by these industry trends. 

On November 20, 1993 the Clinton Administration's healthcare reform proposal, 
the Health Security Act (S.1757/H.R. 3600), was introduced in Congress. The 
stated principal goals of this proposal are to provide health insurance 
coverage to all Americans and to reduce the rate of increase in national 
healthcare expenditures. The plan proposes to reduce total healthcare 
spending by, among other things, limiting the initial premiums and 
year-to-year rates of increase that could be charged by private health plans. 
It also would cut the rate of increase in Medicare spending primarily by 
reducing reimbursement to medical providers. In addition to the Clinton 
Administration's proposal, there are several other competing national 
healthcare reform proposals, as well as legislation and proposed legislation 
in various states. There can be no assurance as to the ultimate content, 
timing or effect of any healthcare reform legislation, nor is it possible at 
this time to estimate the impact of potential legislation on Nichols, which 
could be material. 

The long-term trend in healthcare cost containment involves increasing use of 
managed care plans. Managed care plans typically involve prepaid fixed 
amounts for substantially all of the healthcare needs of a participating 
person coupled with a requirement that a primary care physician review and 
direct the healthcare services provided to that person by a network of 
specialists and other healthcare providers. Many aspects of billing and other 
business arrangements will change as Nichols increasingly deals with managed 
healthcare clients. These arrangements typically involve large negotiated 
contracts for the testing needs of all or a substantial portion of plan 
participants with significant price discounting. Nichols' ability to compete 
successfully in an increasingly managed care environment will depend on its 
ability to obtain contracts with managed care plans or the other purchasing 
and provider alliances that are forming in response to these changes in the 
healthcare industry. 

Government Regulation 
The Reference Laboratories, the Regional Laboratories, the NISAT laboratory 
and certain Company personnel are required to be licensed by certain states 
in which Nichols does business. Nichols is also certified by HCFA pursuant to 
the Clinical Laboratories Improvement Act of 1967 ("CLIA"). CLIA was amended 
in 1988 to provide for stricter oversight of laboratories by HCFA and to 
establish national standards for laboratory performance and quality. The 
regulations adopted pursuant to the 1988 amendment established standards for 
the day-to-day operation of laboratories, and subject large numbers of 
previously exempt facilities to governmental regulation. The federal and 
state certification and licensure programs establish standards for the 
day-to-day operation of a medical laboratory, includ
<PAGE>
<PAGE>
 
ing, but not limited to, personnel and quality control. Compliance with such 
standards is verified by periodic inspections by inspectors employed by the 
appropriate federal or state regulatory agency. In addition, regulatory 
authorities require participation in a proficiency testing program provided 
by an external source which involves actual testing of specimens that have 
been specifically prepared by the regulatory authority for testing by the 
laboratory. 

Among the classes of laboratories most affected by the implementation of 
these regulations are those located in physicians' offices. Physician-owned 
laboratories are also subject to the self-referral provisions of the Omnibus 
Budget Reconciliation Act of 1989 ("OBRA"), which, subject to certain 
exceptions, prohibit a physician from referring clinical laboratory testing 
for Medicare and Medicaid beneficiaries to an entity in which the physician 
has an ownership or an investment interest or with which the physician has 
compensation arrangements. Other provisions of OBRA also negatively impact 
physician-owned and other laboratories which refer large volumes of their 
tests to other laboratories for testing. These provisions prohibit such 
laboratories from billing for services they do not perform themselves, unless 
the referring laboratories actually perform at least 70% of the tests for 
which they receive requests. 

Because of the foregoing regulatory developments, Nichols believes that many 
physician-owned laboratories will incur increased costs due to compliance 
with the new regulations and choose to cease operation or be acquired by 
independent laboratories. Although Nichols receives test referrals from such 
physician-owned laboratories, even if the physician-owned laboratories cease 
doing business, Nichols believes that it will continue to obtain such 
referral business from the successors to these businesses. Nichols further 
believes regulatory requirements do not impose a significant burden on 
Nichols, in part because its existing quality standards meet or exceed 
current regulatory standards. 

In addition to the rules regarding physician-owned laboratories, the 
anti-fraud provisions of statutes relating to Medicare and Medicaid 
reimbursement contain broad statutory prohibitions on conduct that might 
constitute kickbacks or rebates. DHHS has published safe harbor regulations 
which specify certain business activities that, if followed, do not violate 
the Medicare/Medicaid anti-kickback laws. Failure to fall within a safe 
harbor does not constitute a violation of the anti-kickback laws; rather, the 
arrangement would remain subject to scrutiny by DHHS. 

The Reference Laboratories and the Regional Laboratories are also certified 
by HCFA to participate in the Medicare and Medicaid programs. These state and 
federal laws and regulations require Nichols to meet various standards 
governing the qualifications of laboratory owners and personnel and the 
maintenance of proper records, facilities, equipment, test materials and 
quality control programs. Nichols has received certification from DHHS for 
substance abuse testing. See "NISAT." Nichols is subject to a number of other 
state and federal requirements which provide for inspection of Nichols' 
facilities and regulations governing the transportation, packaging and 
labeling of specimens tested by Nichols. Nichols is also subject to 
regulation by those states in which it performs laboratory services, in 
particular the State of California, which has established detailed standards 
for the operation of clinical laboratories, including requirements for 
licensing, training, continuing education, proficiency testing and quality 
control. 

Nichols uses low-level radioactive isotopes in the performance of 
radioimmunoassay tests and in the manufacture of radioimmunoassay kits. 
Various federal, state and local governmental entities regulate the use and 
disposal of radioactive and other hazardous materials. Nichols has not 
experienced any significant problems or liability in connection with such 
materials used or generated in connection with Nichols' testing services or 
kits. Nichols engages the service of independent licensed contractors to 
dispose of such materials and stores certain of its wastes in its own 
facilities until such time as the radioactivity of such materials has 
decreased sufficiently to allow more economical disposal. There can be no 
assurance, however, that Nichols will not at some time in the future 
experience significant problems or liability with respect to such 
governmental regulations or with respect to claims by third parties. 

Certain federal and state laws govern the handling and disposal of infectious 
and hazardous wastes. Although Nichols believes that it is currently in 
compliance in all material respects with such federal and state laws, failure 
to comply could subject Nichols to fines, criminal penalties and/or other 
enforcement actions. 

Nichols believes that, except as disclosed under "OIG Investigation" below, 
it is in compliance in all material respects with all statutes, regulations 
and other requirements applicable to its clinical laboratory operations. The 
clinical laboratory testing industry is, however, subject to extensive 
regulation, and many of those statutes and regulations have not been 
interpreted by the courts. There can be no assurance therefore that 
applicable statutes and regulations might not be interpreted or applied by a 
prosecutorial, regulatory or judicial authority in a manner that would 
adversely affect Nichols. Potential sanctions for violation of these statutes 
and regulations include significant fines and the loss of various licenses, 
certificates and authorizations. Nichols is not aware of any circumstances
<PAGE>
<PAGE>
 
which in its view are likely to result in any such penalty against it. Any 
loss by Nichols, however, of its various federal licenses, its certification 
from DHHS, its authorization to participate in the Medicare and Medicaid 
reimbursement programs or its licenses under the laws of any state from which 
a substantial portion of its revenues are derived would have a material 
adverse effect on its business. 

The federal Food and Drug Administration (the "FDA") requires Diagnostics to 
submit a premarket notification ("510(k)") application to the FDA at least 90 
days before marketing any new kit. If the FDA determines that the kit is 
substantially equivalent to a device already in commercial distribution in 
terms of safety, effectiveness and intended use, it will be recognized by the 
FDA for commercial use. If the FDA determines the kit is not substantially 
equivalent to a device already in commercial distribution, premarket approval 
must be obtained prior to marketing the kit. Premarket approval requires 
submission of a detailed application, including the results of clinical 
tests, which substantially lengthens the approval process. Diagnostics has 
not experienced any significant delays in the introduction of its test kits 
to date. There can be no assurance, however, that any future introduction by 
Diagnostics of new kits will not be delayed significantly by the FDA review 
process. Diagnostics is also required to provide certain information to the 
FDA, to maintain certain records, and to permit periodic inspection of its 
facilities. In addition, the FDA's enforcement activities with respect to 
marketing and promotional activities of diagnostic devices has substantially 
increased over the past year. 

OIG Investigation 
On August 30, 1993, Nichols received a subpoena from the Office of the 
Inspector General of the DHHS (the "OIG subpoena") requesting documents in 
connection with an investigation and internal review being conducted by the 
OIG concerning the possible submission of false or improper claims by Nichols 
to, and their payment by, the Medicare and Medicaid programs. Among other 
things, the OIG subpoena called for the production of documents regarding 14 
blood chemistry tests which were being or had been performed by Nichols in 
conjunction with an automated chemistry panel and which were being or had 
been billed separately to Medicare or Medicaid. An automated chemistry panel 
is a grouping of up to 19 tests that can be performed together and that 
Medicare and Medicaid pay for on a flat fee basis. The 14 tests referenced in 
the OIG subpoena are typically not part of an automated chemistry panel, and 
Medicare and Medicaid pay for these tests as separate items at the lower of 
the prices determined by the relevant Medicare and Medicaid fee schedule or 
the prices actually billed. Other independent clinical laboratories have 
received similar subpoenas which Nichols believes are a part of a nationwide 
audit and investigation. Nichols has not been charged with any violation of 
any statute or regulation and has been cooperating fully in the 
investigation. It is too early to predict the results of the investigation or 
its impact, if any, on Nichols' financial condition or results of operations. 

Nichols is aware that other clinical laboratory companies have entered into 
substantial financial settlements with the government following government 
allegations that their billing practices for blood chemistry tests resulted 
in the submission to the Medicare and Medicaid programs of claims for 
unnecessary services in violation of applicable law. Since none of these 
instances resulted in trials or other public proceedings, Nichols cannot 
determine the specific nature of the government's allegations or legal 
theories. However, based on public reports, Nichols believes that the 
government's investigation is primarily focused on two practices. The first 
practice consists of offering the automated chemistry panel as a part of a 
"standard" blood chemistry profile that also includes one or more of the 14 
tests referenced in the OIG subpoena in a manner which is misleading to the 
ordering physician or which fails to provide the choice of ordering only the 
automated chemistry panel. Representatives of the government have been quoted 
in the press as claiming that this practice may lead to the ordering of 
"unnecessary" tests. The second practice involves the failure of certain 
laboratories to disclose to physicians that the prices charged by those 
laboratories to Medicare and Medicaid for many of the tests referenced in the 
OIG subpoena were greater than the prices the laboratories charged to the 
physicians for those same tests where the tests were performed in conjunction 
with an automated chemistry panel. Nichols' Regional Laboratories have 
included some of the 14 tests in their respective "standard" blood chemistry 
profiles, and also in "custom" profiles created for individual physicians at 
their request. Tests performed for Medicare and Medicaid patients are billed 
directly to the Medicare and Medicaid programs, and Nichols generally does 
not inform physicians of the prices that Medicare and Medicaid are charged 
for those tests. Representatives of the government have been quoted in the 
press as claiming that undisclosed pricing differences may cause physicians 
to believe incorrectly that they are ordering tests at little or no cost to 
the Medicare and Medicaid programs, possibly causing tests to be ordered 
which are not medically necessary. 

If the government were to pursue successfully a claim against Nichols arising 
from the investigation, Nichols could be materially adversely affected 
because potential sanctions include significant fines, recovery of the 
amounts paid to Nichols for the tests involved and mandatory exclusion from 
the Medicare and Medicaid programs for a period of at least five years. 
Currently, Nichols derives approximately 13% of its revenues from testing 
paid for by Medicare and Medicaid. While Nichols understands from published 
reports that none of the major clinical labo
<PAGE>
<PAGE>
 
ratory companies that have entered into settlement agreements with the 
government have been excluded from participation in the Medicare and Medicaid 
programs, there can be no assurance that Nichols or other clinical 
laboratories under investigation will be able to negotiate settlement 
agreements with similar terms. In addition, the bringing of a criminal 
indictment or the filing of a civil fraud or false claims action which, if 
successful, would result in the exclusion of Nichols from the Medicare and 
Medicaid programs, or any such exclusion, would have the effect of making it 
difficult for Nichols to compete for non-Medicare and non-Medicaid business 
because clients often want a single laboratory to handle all of their testing 
business. As discussed above, however, no claim has been asserted against 
Nichols and it is too early to predict the results of the investigation or 
its impact on Nichols' financial condition or results of operations. 
Accordingly, no provision for losses, if any, that may result upon the 
resolution of this investigation has been made in the accompanying financial 
statements. Nichols has incurred significant costs in responding to requests 
in connection with this investigation and expects such costs to continue 
through 1994. 

Raw Materials and Supplies 
Nichols purchases substantially all of its raw materials (primarily 
chemicals) and supplies from various commercial sources in the United States. 
Nichols is not dependent upon any one or a limited number of suppliers and 
has not experienced any difficulties in obtaining necessary supplies. Nichols 
has not experienced any shortage in the available supplies of radioactive 
isotopes, used in performing certain tests, and, because Nichols' use of 
isotopes is for medical purposes, Nichols does not anticipate that any future 
changes in the regulation of these materials would materially adversely 
affect its operations. 

Employees 
On June 30, 1994, Nichols had the equivalent of approximately 3,500 full-time 
employees. Nichols' employees have never been covered by a collective 
bargaining agreement. Nichols has never experienced any work stoppages, 
slowdowns or other serious labor problems and considers relations with its 
employees to be good.

(1) The mortgage balance associated with this facility is included in the 
mortgage balance for Sioux Falls, SD. 

(2) The initial term of this lease expires in 2011, with options to extend 
the term through March 2046. For accounting purposes, Nichols has assumed 
that the term of the lease will be extended through March 2031. 

Certain of the leases summarized above contain provisions for extensions. 
Nichols leases other smaller laboratory facilities for local rapid response 
laboratories, specimen collection sites, and offices for regional sales 
management and couriers in various states, under varying terms of occupancy 
including month-to-month tenancies. 

Lease of Principal Facility.  In order to accommodate its then current and 
anticipated future needs, in 1989 Nichols entered into agreements with a 
developer for the financing and development of new laboratory and 
administrative facilities on approximately 100 acres of real property owned 
by Nichols in San Juan Capistrano (Orange County), California. 

The agreements include a lease of a portion of the land owned by Nichols to a 
developer and a leaseback of the land and buildings by the developer to 
Nichols. Nichols relocated its San Juan Capistrano-based laboratory, research 
and development and administrative activities to the new facility during the 
third quarter of 1991. The transaction has been accounted for as a capital 
lease commencing in August 1991, and continuing through March 2031. The total 
cost of new facilities, including water and sewer facilities which are 
maintained and operated by a local utility company and significant amounts of 
fixtures, equipment and furnishings, approximated $61.0 million, of which 
approximately $8.0 million (land and development costs) was incurred prior to 
1991. Of the costs incurred in 1991, approximately $32.5 million was financed 
under the capital lease. The amount of rent payable by Nichols under the 
lease is currently approximately $3.8 million per year. 

Rent under the lease to Nichols is subject to escalation every five years 
based upon changes in a designated consumer price index. Nichols has the 
option to purchase the building and terminate the lease at various times 
during the lease term at a formula price which varies over time. 

Legal Proceedings 
From time to time, claims have been made against Nichols relating to the 
performance of its business, but Nichols has not previously experienced any 
significant liability with respect to such claims or in connection with use 
of its diagnostic kits or its substance abuse testing. Although Nichols 
maintains insurance against these risks, including medical malpractice and 
product liability, there can be no assurance that Nichols will not at some 
time in the future experience significant liability in this regard. Nichols 
believes that its insurance coverage is adequate.

(3) Holders of Series E Convertible Preferred Stock originally received their 
shares in connection with Nichols' acquisition of MAWD Medical Laboratories, 
Inc. ("MAWD") in January 1991. All of the holders of Series E Convertible 
Preferred Stock indicated above were prior stockholders of MAWD, and each of 
their addresses is 6501 E. Commerce Avenue, Suite 101, Kansas City, MO 64120. 

(4) Includes 3,818 shares of Class A Common Stock, 42,470 shares of Class B 
Common Stock and 45,842 shares of Class C Common Stock held as trustee for 
the benefit of certain family members. Because of his ownership of a 
substantial amount of the Class B Common Stock, Dr. Nichols may be deemed a 
"parent" of Nichols pursuant to regulations adopted by the Securities and 
Exchange Commission. Dr. Nichols' business address is 33608 Ortega Highway, 
San Juan Capistrano, CA 92690. 

(5) Morgan Stanley Group, Inc. ("Morgan Stanley") reported on Schedule 13F 
dated March 31, 1994 that it was the beneficial owner of such shares and 
stated that it has no voting power with respect to 260,000 such shares
<PAGE>
<PAGE>
 
and has voting power with respect to 50,000 such shares and shared 
dispositive power with respect to such shares. Morgan Stanley is an 
investment advisory firm, and its address is 1251 Avenue of the Americas, New 
York, New York 10020. Nichols is unaware of any subsequent change in 
beneficial ownership. 

(6) The State of Wisconsin Investment Board (the "Wisconsin Investment 
Board") reported on Schedule 13G dated February 8, 1994, that it was the 
beneficial owner of such shares and stated that it has sole voting power and 
sole dispositive power with respect to such shares. The Wisconsin Investment 
Board's address is P.O. Box 7842, Madison, WI 53707. Nichols is unaware of 
any subsequent change in beneficial ownership. 

(7) The percentages set forth above are based upon the number of shares 
outstanding and do not reflect that (except when they vote as a class on the 
election and removal of directors and on other matters required by law) 
holders of Class A Common Stock and Class B Common Stock vote together as a 
single class or that holders of Class A Common Stock are entitled to 
one-tenth of a vote per share and holders of Class B Common Stock are 
entitled to one vote per share. As of the date of the table, Albert L. 
Nichols, M.D., and the directors and executive officers as a group had 
approximately 60.4% and 61.6%, respectively, of the voting power of Class A 
Common Stock and Class B Common Stock voting as a single class. Holders of 
Class C Common Stock are not entitled to vote except on certain matters where 
a class vote is required by law and on certain business combinations. Holders 
of Series E Convertible Preferred Stock are also not entitled to vote except 
on such matters as are provided by law or the Certificate of Designation of 
Powers, Designations, Preferences and Rights by which the Series E 
Convertible Preferred Stock was created. 

Dr. Nichols has pledged 750,000 of his shares of Class B Common Stock and 
700,000 of his shares of Class C Common Stock as collateral for a term loan 
(the "Loan") in the current principal amount of approximately $1.4 million to 
Dr. Nichols by Citicorp USA, Inc. (the "Lender"). Pursuant to the terms and 
conditions of the Loan, an event of default would occur if, among other 
things, the loan-to-value ratio under the Loan exceeds 0.4 to 1.00. If the 
loan-to-value ratio should exceed 0.4 to 1.00, Dr. Nichols would be required 
to reduce the ratio to 0.25 to 1.00 either by pledging additional securities 
or by reducing the amount outstanding under the Loan. If Dr. Nichols did not 
so reduce the loan-to-value ratio or if other defaults under the Loan were to 
occur, the Lender would have the right to sell the pledged shares of Class C 
Common Stock or to convert the pledged shares of Class B Common Stock to 
Class A Common Stock and to sell shares of Class A Common Stock (but only 
after selling the pledged shares of Class C Common Stock), in order to use 
the proceeds of any such sales to reduce the amount outstanding pursuant to 
the Loan. Based on closing stock prices on the date immediately preceding the 
announcement of the Merger, May 31, 1994 ($4.813 per share of Class A Common 
Stock and $4.125 per share of Class C Common Stock) and the amount 
outstanding under the Loan as of the date of this Proxy Statement/Prospectus 
(approximately $2.175 million), the loan-to-value ratio would be 0.33 to 
1.00. Based on closing stock prices on June 30, 1994 ($11.875 per share of 
Class A Common Stock and $11.75 per share of Class C Common Stock) and the 
amount outstanding under the Loan as of the date of this Proxy 
Statement/Prospectus (approximately $2.175 million), the loan-to-value ratio 
would be 0.13 to 1.00. Assuming the amount outstanding under the Loan 
continues to be approximately $2.175 million, the loan-to-value ratio would 
not exceed 0.4 to 1.00 unless the average stock price per pledged share fell 
to $3.75. 

                     DESCRIPTION OF CORNING CAPITAL STOCK 

General 
The following is a brief summary of certain provisions of the Restated 
Certificate of Incorporation of Corning (the "Restated Certificate") and does 
not relate to or give effect to provisions of statutory or other law except 
as specifically stated. The Restated Certificate authorizes the issuance of 
500,000,000 Corning Common Shares. As of July 14, 1994, 213,736,161 Corning 
Common Shares were outstanding. The rights of holders of Corning Common 
Shares are governed by the Restated Certificate, Corning's By-Laws and by the 
New York Business Corporation Law (the "NYBCL"). 

Voting Rights 
Subject to the voting of any shares of Series Preferred Stock (as defined 
below) that may be outstanding, voting power is vested in the Corning Common 
Shares, each share having one vote. 

Preemptive Rights 
The Restated Certificate provides that no holder of Corning Common Shares or 
Series Preferred Stock shall have any preemptive rights except as the Corning 
Board may determine from time to time. No such rights have been granted by 
the Corning Board.
<PAGE>
<PAGE>
 
Corning Common Shares 
Liquidation Rights. Subject to the preferential rights of any outstanding 
Series Preferred Stock, in the event of any liquidation of Corning, holders 
of Corning Common Shares then outstanding are entitled to share ratably in 
the assets of Corning available for distribution to such holders. 

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

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

Series Preferred Stock 
The Restated Certificate authorizes the issuance of up to 10,000,000 shares 
of Series Preferred Stock, par value $100 per share (the "Series Preferred 
Stock"). The Corning Board has the authority to issue such shares from time 
to time, without stockholder approval, and the authority to determine the 
designations, preferences, rights, including voting rights, and restrictions 
of such shares, subject to the NYBCL. Pursuant to this authority, the Corning 
Board has designated 600,000 shares of Series Preferred Stock as Series A 
Preferred Stock, 316,822 shares of Series Preferred Stock as Series B 
Preferred Stock (the "Series B Preferred Stock"), and an as yet unspecified 
number of shares of Series Preferred Stock as Series C Preferred Stock. No 
other class of Series Preferred Stock has been designated by the Corning 
Board. 

Series B Preferred Stock 

Cumulative cash dividends at the rate of 8% per annum are payable on shares 
of the Series B Preferred Stock that have been issued. Corning has regularly 
paid dividends on the Series B Preferred Stock. No dividends may be paid or 
declared on the Series A Preferred Stock or the Corning Common Shares unless 
all dividends for all prior dividend periods have been paid or declared on 
the Series B Preferred Stock, the Series C Preferred Stock and the preferred 
securities. 

Holders of Series B Preferred Stock are entitled to vote, voting together 
with the Corning Common Shares and not as a separate class, on all matters 
submitted to holders of the Corning Common Shares, each share of Series B 
Preferred Stock having four votes, subject to adjustment. 

Holders of Series B Preferred Stock have no preemptive rights. In the event 
of a liquidation, dissolution or winding-up of Corning, holders of Series B 
Preferred Stock shall be entitled to receive a distribution in the amount of 
$100 per share, plus accrued and unpaid dividends, before any distribution on 
the Corning or Series A Preferred Stock. 

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

<TABLE>

Month Period                                             Price Per

1994                                                       $103.00 
1995                                                       $102.00 
1996                                                       $101.00 
</TABLE>
and thereafter at $100.00 per share plus, in each case, accrued and unpaid 
dividends. 

The Series B Preferred Stock is subject to redemption, at the option of the 
holder, at any time upon five business days' notice, at a redemption price 
equal to $100.00 plus accrued and unpaid dividends, if the proceeds are 
necessary (i) to make a distribution pursuant to an investment election made 
under the employee benefit plan or (ii) to satisfy any indebtedness to which 
the employee benefit plan is subject, provided that such payment is necessary 
to remedy or prevent a default under such indebtedness. 

Corning, at its option, may make payment of the redemption price required 
upon redemption of shares of Series B Preferred Stock in cash or in Corning 
Common Shares, or in any combination of such shares and cash.
<PAGE>
<PAGE>
 
The Series B Preferred Stock is convertible at the option of the holder, at 
any time, into Corning Common Shares at a conversion price of $25.00 per 
Corning Common Share, each share of Series B Preferred Stock being valued at 
$100 for the purpose of such conversion, producing a conversion ratio equal 
to four Corning Common Shares for each share of Series B Preferred Stock so 
converted, subject to certain adjustments to prevent dilution. 

Series C Preferred Stock 

As described under "BUSINESS OF CORNING--Recent Developments", in connection 
with the MIPs Offering by Corning Delaware, the Corning Board designated, on 
April 28, 1994, the Series C Preferred Stock. 

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

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

The Series C Preferred Stock ranks senior to the Corning Common Stock and the 
Series A Preferred Stock with respect to the payment of dividends and amounts 
on liquidation, dissolution and winding-up. In the event of a voluntary or 
involuntary bankruptcy, liquidation, dissolution or winding-up of Corning, 
the holders of Series C Preferred Stock are entitled to receive out of the 
net assets of Corning, but before any distribution is made on any class of 
securities ranking junior to the Series C Preferred Stock, $100.00 per share 
in cash plus accumulated and unpaid dividends (whether or not earned or 
declared) to the date of final distribution to such holders. 

Preferred Share Purchase Rights 
Attached to each Corning Common Share is one Right, which entitles the 
registered holder to purchase from Corning one four-hundredth of a share of 
Series A Preferred Stock at a price of $62.50 per one four-hundredth of a 
share of Series A Preferred Stock (the "Exercise Price"), subject to 
adjustment. The Rights expire on July 15, 1996 (the "Final Expiration Date"), 
unless the Final Expiration Date is extended or unless the Rights are earlier 
redeemed by Corning. 

The Rights represented by the certificates for Corning Common Shares, are not 
exercisable, and are not transferable apart from the Corning Common Shares, 
until the earlier of (i) ten days following the public announcement by 
Corning or an Acquiring Person (as defined below) that a person or group has 
acquired beneficial ownership of 20% or more of the Corning Common Shares (an 
"Acquiring Person") or (ii) ten business days (or such later date as the 
Corning Board may determine) after the commencement or first public 
announcement of a tender or exchange offer that would result in a person or 
group beneficially owning 20% or more of the Corning Common Shares (the 
earlier of such dates being called the "Distribution Date"). Separate 
certificates for the Rights will be mailed to holders of record of the 
Corning Common Shares as of such date. The Rights could then begin trading 
separately from the Corning Common Shares. 

Generally, in the event that a person or group becomes an Acquiring Person, 
each Right, other than the Rights owned by the Acquiring Person, will 
thereafter entitle the holder to receive, upon exercise of the Right, Corning 
Common Shares having a value equal to two times the Exercise Price of the 
Right. In the event that Corning is acquired in a merger, consolidation, or 
other business combination transaction or more than 50% of Corning's assets, 
cash flow or earning power is sold or transferred, each Right, other than the 
Rights owned by an Acquiring Person, will thereafter entitle the holder 
thereof to receive, upon the exercise of the Right, common stock of the 
surviving corporation having a value equal to two times the Exercise Price of 
the Right. 

The Rights are redeemable in whole, but not in part, at $.0125 per Right at 
any time on or prior to any person or group becoming an Acquiring Person. The 
right to exercise the Rights terminates at the time that the Corning Board 
elects to redeem the Rights. Notice of redemption shall be given by mailing 
such notice to the registered holders of the Rights. At no time will the 
Rights have any voting rights. The Rights Agent is Harris Trust and Savings 
Bank (the "Rights Agent"). 

The exercise price payable, and the number of shares of Series A Preferred 
Stock or other securities or property issuable, upon exercise of the Rights 
are subject to adjustment from time to time to prevent dilution (i) in the 
event of a stock dividend on, or a subdivision, combination or 
reclassification of, the shares of Series A Preferred Stock, (ii) upon the 
grant to holders of the shares of Series A Preferred Stock of certain rights 
or warrants to subscribe for or purchase shares of Series A Preferred Stock 
at a price, or securities convertible into shares of Series A Preferred Stock 
with a conversion price, less than the then current market price of the 
shares of Series A Preferred
<PAGE>
<PAGE>
 
Stock or (iii) upon the distribution to holders of the shares of Series A 
Preferred Stock of evidences of indebtedness or assets (excluding regular 
periodic cash dividends paid out of earnings or retained earnings or 
dividends payable in shares of Series A Preferred Stock) or of subscription 
rights or warrants (other than those referred to above). 

The number of outstanding Rights and the number of one four-hundredths of a 
share of Series A Preferred Stock issuable upon exercise of each Right are 
also subject to adjustment in the event of a stock split of, or stock 
dividend on, or subdivision, consolidation or combination of, the Corning 
Common Shares prior to the Distribution Date. With certain exceptions, no 
adjustment in the exercise price will be required until cumulative 
adjustments require an adjustment of at least 1% in such exercise price. 

Upon exercise of the Rights, no fractional shares of Series A Preferred Stock 
will be issued (other than fractions which are integral multiples of one 
four-hundredth of a share, which may, at the election of Corning, be 
evidenced by depositary receipts) and in lieu thereof an adjustment in cash 
will be made. 

The Rights have certain anti-takeover effects. The Rights may cause 
substantial dilution to a person or group that attempts to acquire Corning on 
terms not approved by the Corning Board, except pursuant to an offer 
conditioned on a substantial number of Rights being acquired. The Rights 
should not interfere with any merger or other business combination approved 
by the Corning Board since the Rights may be redeemed by Corning at $.0125 
per Right prior to the fifteenth day after the acquisition by a person or 
group of beneficial ownership of 20% or more of the Corning Common Shares 
(subject to certain exceptions). 

The shares of Series A Preferred Stock purchasable upon exercise of the 
Rights will rank junior to all other series of Corning's preferred stock 
(including the Series B and Series C Preferred Stock) or any similar stock 
that specifically provides that they shall rank prior to the shares of Series 
A Preferred Stock. The shares of Series A Preferred Stock will be 
nonredeemable. Each share of Series A Preferred Stock will be entitled to a 
minimum preferential quarterly dividend of $10.00 per share, but will be 
entitled to an aggregate dividend of 100 times the dividend declared per 
share of Corning Common Shares. In the event of liquidation, the holders of 
the shares of Series A Preferred Stock will be entitled to a minimum 
preferential liquidation payment of $100 per share, but will be entitled to 
an aggregate payment of 100 times the payment made per share of Corning 
Common Shares. Each share of Series A Preferred Stock will have 100 votes, 
voting together with the Corning Common Shares. In the event of any merger, 
consolidation or other transaction in which Corning Common Shares are 
exchanged, each share of Series A Preferred Stock will be entitled to receive 
100 times the amount and type of consideration received per Corning Common 
Share. These rights are protected by customary antidilution provisions. 
Because of the nature of the Series A Preferred Stock's dividend, liquidation 
and voting rights, the value of the interest in a share of Series A Preferred 
Stock purchasable upon the exercise of each Right should approximate the 
value of one Corning Common Share. 

The foregoing description of the Rights does not purport to be complete and 
is qualified in its entirety by reference to the description of the Rights 
contained in the Rights Agreement, dated as of July 2, 1986 between Corning 
and the Rights Agent, as amended by the Amended Rights Agreement, dated as of 
October 4, 1989, which has been previously filed with the SEC. 

Corning's Fair Price Amendment 
In 1985, Corning's stockholders adopted an amendment (the "Fair Price 
Amendment") to the Restated Certificate that, in general, requires the 
approval by the holders of at least 80% of the voting power of the 
outstanding capital stock of Corning (other than the Series C Preferred 
Stock) entitled to vote generally in the election of directors (the "Corning 
Voting Stock") as a condition for mergers and certain other business 
combinations with any beneficial owner of more than 10% of such voting power 
unless (1) the transaction is approved by at least a majority of the 
Continuing Directors (as defined in the Restated Certificate) or (2) certain 
minimum price, form of consideration and procedural requirements are met. 
Certain terms used herein are defined in the Restated Certificate. 

Amendment or repeal of this provision or the adoption of any provision 
inconsistent therewith would require the affirmative vote of at least 80% of 
the Corning Voting Stock unless the proposed amendment or repeal or the 
adoption of the inconsistent provisions were approved by two-thirds of the 
entire Corning Board and a majority of the Continuing Directors. 

Certain Other Provisions of the Restated Certificate and By-Laws 
In addition to the Preferred Share Purchase Rights and the Fair Price 
Amendment, the Restated Certificate and By-Laws contain other provisions that 
may discourage a third party from seeking to acquire Corning or to commence a 
proxy contest or other takeover-related action. Corning has classified the 
Corning Board such that one-third of the Corning Board is elected each year 
to three-year terms of office. In addition, holders of Corning Common Shares 
may remove a director from office at any time prior to the expiration of his 
or her term only with cause and by vote of a majority of holders of Corning 
Common Shares outstanding. These provisions, together with pro
<PAGE>
<PAGE>
 
visions concerning the size of the Corning Board and requiring that premature 
vacancies on the Corning Board be filled only by a majority of the entire 
Corning Board, may not be amended, altered or repealed, nor may Corning adopt 
any provisions inconsistent therewith, without the affirmative vote of at 
least 80% of the Corning Voting Stock of Corning or the approval of 
two-thirds of the entire Corning Board. 

Corning's By-Laws contain certain procedural requirements with respect to the 
nomination of directors by stockholders that require, among other things, 
delivery of notice by such stockholders to the Secretary of Corning not later 
than 60 days nor more than 90 days prior to the date of the stockholders 
meeting at which such nomination is to be considered. The Corning By-Laws do 
not provide that a meeting of the Corning Board may be called by 
stockholders. 

The Restated Certificate provides that no director will be liable to Corning 
or its stockholders for a breach of duty as a director except as provided by 
the NYBCL. 

The effect of these provisions may be to deter attempts either to obtain 
control of Corning or to acquire a substantial amount of its stock, even if 
such a proposed transaction were at a significant premium over the 
then-prevailing market value of the Corning Common Shares, or to deter 
attempts to remove the Corning Board and management of Corning, even though 
some or a majority of the holders of Corning Common Shares may believe such 
actions to be beneficial. 

                     DESCRIPTION OF NICHOLS CAPITAL STOCK 

The following descriptions are summarized from the provisions of the Nichols 
Certificate of Incorporation. 

Nichols' authorized capital stock consists of (i) 20,000,000 shares of Class 
A Common Stock, $0.10 par value, (ii) 13,333,333 shares of Class B Common 
Stock, $0.10 par value, (iii) 30,000,000 shares of Class C Common Stock, 
$0.10 par value and (iv) 1,000,000 shares of preferred stock, $0.10 par 
value. 

Common Stock 
Voting for Election and Removal of Directors. Subject to certain exceptions 
described below, holders of Class A Common Stock are entitled to one-tenth of 
a vote per share and are entitled as a class to elect 25% of the Board of 
Directors (currently two of the eight Directors), with cumulative voting for 
directors being permitted. Holders of Class B Common Stock are entitled to 
one vote per share and are entitled as a class to elect 75% of the Board of 
Directors (currently six of the eight directors), with cumulative voting 
permitted. Holders of each of the two classes also vote separately as single 
classes on (i) removal of directors elected by their respective class and 
(ii) filling vacancies in the offices of directors elected by their 
respective class. Holders of Class C Common Stock have no voting rights with 
respect to the election or removal of directors, or with respect to the 
filling of vacancies on the Board of Directors. 

Nichols' Certificate of Incorporation provides that if the number of 
outstanding shares of Class A Common Stock is more than 87.5% of the combined 
number of outstanding shares of Class A Common Stock and Class B Common 
Stock, the holders of Class B Common Stock in effect lose their special 
voting rights with respect to the election of directors. In such an event, 
all holders of Class A Common Stock and Class B Common Stock will have one 
vote per share and will vote together as a single class for the election of 
all directors. In addition, if the number of shares of Class A Common Stock 
outstanding is less than 10% of the combined number of shares of Class A 
Common Stock and Class B Common Stock outstanding, the holders of Class A 
Common Stock will vote together with the holders of Class B Common Stock as a 
single class to elect all directors, with the holders of Class A Common Stock 
entitled to one-tenth of a vote per share and the holders of Class B Common 
Stock entitled to one vote per share. 

As of July 27, 1994, the holders of Class B Common Stock possess effective 
control of Nichols through holding more than 72% of the combined voting power 
of the outstanding capital stock of Nichols and the ability to elect a 
majority of the members of the Nichols Board. Furthermore, as of July 27, 
1994, Dr. Nichols has the power to elect five of Nichols' eight directors 
through his beneficial ownership of approximately 84% of the outstanding 
shares of Class B Common Stock, representing approximately 60% of the 
combined voting power of Nichols' outstanding capital stock. 

Voting on Mergers, Consolidations and Other Business Combinations. The 
Nichols Certificate of Incorporation includes provisions that are intended to 
cause the holders of the Class A Common Stock, Class B Common Stock and the 
Class C Common Stock to be treated equally with respect to mergers, 
consolidations and certain other business combinations ("Combinations"). It 
requires that, unless certain conditions are satisfied, such Combinations 
must be approved by the holders of a majority of the outstanding shares of 
each of the three classes of
<PAGE>
<PAGE>
 
stock, voting as separate classes. The Nichols Board has determined these 
conditions have been satisfied with respect to the Merger and, therefore, 
there will not be any separate class voting with respect to adoption of the 
Merger Agreement. See "BACKGROUND AND REASONS FOR THE MERGER; RECOMMENDATION 
OF THE NICHOLS BOARD" and "COMPARATIVE RIGHTS OF NICHOLS STOCKHOLDERS AND 
CORNING STOCKHOLDERS--Business Combinations--Mergers and Consolidations of 
Nichols Which Are Not Related Person Business Combinations." 

Voting on Other Matters. On all matters other than the election and removal 
of Directors and the filling of vacancies on the Board of Directors and 
except as described above with respect to certain Combinations and as 
otherwise required by Delaware law, the holders of Class A Common Stock and 
the holders of Class B Common Stock vote together as a single class, with the 
holders of the Class A Common Stock entitled to one-tenth of a vote per share 
and the holders of the Class B Common Stock entitled to one vote per share. 

The holders of Class C Common Stock are not entitled to vote on any question 
presented to the stockholders of Nichols, except (i) as described above with 
respect to certain Combinations and (ii) as required under DGCL. Pursuant to 
Delaware law, the holders of Class C Common Stock are entitled to vote with 
respect to any proposed amendment to the Certificate of Incorporation which 
would increase or decrease the par value of a share of Class C Common Stock 
or alter or change the powers, preferences or special rights of the shares of 
that class so as to adversely affect holders of such shares. 

Dividends and Distribution Rights 

Dividends. The holders of all three classes of Nichols Common Stock are 
entitled to share ratably in any dividends declared by the Nichols Board, 
subject to the preferential rights of any series of Preferred Stock issued 
and outstanding at the time the dividend is declared. 

Other Distributions. If Nichols were liquidated, dissolved or wound up, 
whether voluntarily or involuntarily, the holders of all three classes of 
Nichols Common Stock would receive the same distributions per outstanding 
share, subject to the preferential rights of any series of Nichols Preferred 
Stock then outstanding. 

Conversion Rights. Each holder of Class B Common Stock may, in such holder's 
sole discretion and at such holder's option, convert such holder's shares of 
Class B Common Stock into fully paid and non-assessable shares of Class A 
Common Stock at the rate of one share of Class A Common Stock for each share 
of Class B Common Stock surrendered for conversion, subject to adjustment 
from time to time as provided in Nichols' Certificate of Incorporation in the 
event of any capital reorganization, consolidation or merger of Nichols. 

Preferred Stock 
The Board of Directors of Nichols has the authority to provide for the 
issuance of any series of Preferred Stock, the number of shares included in 
such series, the voting powers, designations, preferences and other rights, 
if any, of such series and the qualifications, limitations or restrictions 
thereof, and to increase or decrease the number of shares of any such series 
(but not below the number of shares thereof then outstanding) of such series. 
The number of authorized shares of Preferred Stock may be increased or 
decreased (but not below the number of shares thereof then outstanding) by 
affirmative vote of the holders of a majority of the stock of Nichols 
entitled to vote irrespective of Section 242 of the DGCL, which requires that 
such an increase or decrease be voted upon by the holders of the Preferred 
Stock voting as a separate class. In 1990, the Nichols Board authorized the 
issuance of the Nichols Preferred Stock. 

Voting Rights. Except as otherwise required by law, holders of Nichols 
Preferred Stock have no voting rights; provided, however, that Nichols 
cannot, without the vote of the holders of a majority of the Nichols 
Preferred Stock voting as a single class: 

  (i) amend or change the Certificate of Incorporation of Nichols so as to 
amend or change any of the rights, preferences or privileges of or 
limitations provided in the Certificate of Incorporation for the benefit of 
any shares of Nichols Preferred Stock; 

 (ii) change or alter the conversion price or alter or cancel the conversion 
provisions of any Nichols Preferred Stock; or 

(iii) alter any provision in the Certificate of Incorporation requiring the 
vote of the holders of a specified percentage of the number of shares of the 
Nichols Preferred Stock. 

Dividends. The holders of Nichols Preferred Stock are entitled to receive 
dividends at the rate of $26.25 per share per annum, which dividends shall 
accrue whether or not earned or declared, beginning on the second anniversary 
of the date of the original issuance of the first share of such stock 
(January 4, 1993) and continuing through
<PAGE>
<PAGE>
 
January 4, 1995. Dividends are cumulative and payable in cash quarterly on 
the first days of January, April, July and October, beginning on April 1, 
1993 and ending on April 1, 1995. Dividends payable to holders of Nichols 
Preferred Stock must be paid prior to any distributions to holders of Nichols 
Common Stock. 

Liquidation, Dissolution or Winding Up. In the event of the liquidation, 
dissolution or winding up of Nichols, the holders of shares of Nichols 
Preferred Stock are entitled to $350.00 per share and the amount, if any, of 
accrued and unpaid dividends, before any payment or declaration can be made 
in respect of Nichols' Common Stock. 

Voluntary Redemption by Nichols. Nichols may, at its option, redeem at any 
time, in whole or in part, the outstanding shares of Nichols Preferred Stock. 
The redemption price is $350.00 per share plus accrued and unpaid dividends. 

Conversion 

The Nichols Preferred Stock is convertible into Class A Common Stock on the 
following terms and conditions: 

  Voluntary Conversion by Holder. Each share of Nichols Preferred Stock may, 
at any time and at the option of its holder, be converted into Class A Common 
Stock; provided, however, that such shares may not be converted after the 
third day preceding the date, if any, fixed by the Board of Directors to 
redeem the Nichols Preferred Stock. Each share of Nichols Preferred Stock is 
convertible into the number of shares of Class A Common Stock which results 
from dividing (i) the sum of $350.00 plus the amount of any accrued and 
undeclared dividends by (ii) the conversion price in effect at the time of 
conversion. The conversion price is $35.00 per share, subject to adjustment 
for stock subdivisions and combinations and certain dividends and 
distributions. 

  Automatic Conversion. The Nichols Preferred Stock shall automatically be 
converted into Class A Common Stock on the first to occur of the following: 

    (i) if and when, prior to January 4, 1995, the market price of one share 
of Class A Common Stock equals or exceeds the conversion price on at least 
ten out of 20 consecutive trading days; 

   (ii) the close of trading on January 4, 1995; provided, however, that if 
the Class A Common Stock on the date of such automatic conversion is not 
listed on a national securities exchange, included in the NASDAQ National 
Market System or otherwise included in the NASDAQ System, then the Nichols 
Preferred Stock shall not be automatically convertible until such time as the 
Class A Common Stock is so listed or traded for one year; and 

  (iii) the occurrence of any merger, consolidation, reorganization, sale, 
reclassification or other transaction in which the outstanding Class A Common 
Stock is to be exchanged for common stock or securities of another entity, or 
for cash or other property, or in which the outstanding Class A Common Stock 
is to be exchanged for other securities and/or rights to such other 
securities ("Merger or Exchange"). 

In general, each share of Nichols Preferred Stock is convertible into the 
number of shares of Class A Common Stock which results from dividing (i) the 
sum of $350 plus the amount of any accrued and undeclared dividends (subject 
to adjustment for, among other things, stock subdivisions and combinations, 
dividends and distributions) by (ii) the conversion price in effect at the 
time of conversion. Except with respect to Mergers or Exchanges, the current 
conversion price is $70.00 and is subject to certain adjustments for, among 
other things, stock subdivisions and combinations, dividends and 
distributions; provided, however, on January 4, 1995, the conversion price 
will be equal to twice the average per-share market price of Nichols' Class A 
Common Stock for the 20-day period ending on that date. Upon the occurrence 
of a Merger or Exchange, in general, the conversion price will be equal to 
$70.00 or, if lower, the value determined by the Nichols Board of the 
consideration to be received in exchange for one share of Nichols Common 
Stock. As a result of the Merger, the outstanding shares of Nichols Preferred 
Stock will convert directly into Corning Common Shares in the manner and 
amount provided for pursuant to the terms of the Nichols Preferred Stock. 

                        COMPARATIVE RIGHTS OF NICHOLS 
                    STOCKHOLDERS AND CORNING STOCKHOLDERS 

If the Merger is consummated, holders of Nichols Common Stock will become 
holders of Corning Common Shares and the rights of the former Nichols 
stockholders will be governed by the laws of the State of New York and by the 
Corning Certificate of Incorporation and the Corning By-Laws, as amended (the 
"Corning By-Laws"). The rights of Corning stockholders under the Corning 
Certificate of Incorporation and the Corning By-Laws differ in certain 
respects from the rights of Nichols stockholders under the Nichols 
Certificate of Incorporation and the
<PAGE>
<PAGE>
 
Nichols By-Laws. Certain differences between the rights of Corning 
stockholders and Nichols stockholders are summarized below. This summary is 
qualified in its entirety by reference to the full text of such documents. 
For information as to how such documents may be obtained, see "AVAILABLE 
INFORMATION." 

Beneficial Ownership of Stock 
The outstanding equity of Nichols is owned approximately 15.3% by Dr. Nichols 
and 15.7% by the directors and management of Nichols as a group. As a result 
of the disproportionate voting rights between the Class A Common Stock and 
the Class B Common Stock, Dr. Nichols holds approximately 60% of the combined 
voting power of the Nichols Common Stock and therefore has the power, among 
other things, to elect a majority of the Nichols Board and to assure adoption 
of the Merger Agreement by the Nichols stockholders. See "SECURITY OWNERSHIP 
OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT OF NICHOLS." 

The Corning Common Shares are widely held. 

Business Combinations 
Generally, under the DGCL, the approval by the affirmative vote of the 
holders of a majority of the outstanding stock (or, if the certificate of 
incorporation provides for more or less than one vote per share, a majority 
of the votes of the outstanding stock) of a corporation entitled to vote on 
the matter is required for a merger or consolidation or sale, lease or 
exchange of all or substantially all the corporation's assets to be 
consummated. 

The Nichols Certificate of Incorporation was amended in June 1991 to 
incorporate several provisions concerning stockholder approval of certain 
mergers or consolidations. 

Mergers and Consolidations of Nichols Which are Not Related Person Business 
Combinations. Except as otherwise provided below for "Related Person Business 
Combinations", a merger or consolidation as a result of which the outstanding 
shares of Class A Common Stock, Class B Common Stock and/or Class C Common 
Stock are converted into, exchanged for or otherwise transferred for cash, 
securities or other property requires the affirmative vote of the holders of 
a majority of the outstanding shares of Class A Common Stock, voting as a 
separate class, unless the "Equal Consideration Requirement" set forth below 
is satisfied as to Class A Common Stock. Likewise, except as provided below 
for Related Party Business Combinations, such a merger or consolidation 
requires the affirmative vote of the holders of a majority of the outstanding 
shares of Class C Common Stock, voting as a separate class, unless the Equal 
Consideration Requirement is satisfied as to the Class C Common Stock. 

The "Equal Consideration Requirement" referred to above is satisfied as to 
the Class A Common Stock and the Class C Common Stock with respect to any 
merger or consolidation in which the holders of the Class A Common Stock, 
Class B Common Stock and Class C Common Stock are to receive cash, securities 
or other property for their shares identical on a per outstanding share basis 
to the cash, securities or other property which the holders of the other such 
classes of stock are to receive in the merger or consolidation. 

If the consideration to be received in a merger or consolidation by the 
holders of the Class A Common Stock is not identical (on a per outstanding 
share basis) to the consideration to be received by the holders of the Class 
B Common Stock or Class C Common Stock, the Equal Consideration Requirement 
is satisfied as to the Class A Common Stock only if the consideration to be 
received by the holders of the Class A Common Stock per outstanding share is 
identical to the consideration to be received per outstanding share by the 
holders of the class of stock (Class B Common Stock or Class C Common Stock) 
whose holders are to receive per share consideration having the greater fair 
market value. 

Likewise, if the consideration to be received in a merger or consolidation by 
the holders of the Class C Common Stock is not identical (on a per 
outstanding share basis) to the consideration to be received by the holders 
of the Class A Common Stock or Class B Common Stock, the Equal Consideration 
Requirement is satisfied as to the holders of Class C Common Stock only if 
the consideration to be received by the holders of the Class C Common Stock 
per outstanding share is identical to the consideration to be received per 
outstanding share by the holders of the class of stock (Class A Common Stock 
or Class B Common Stock) whose holders are to receive per share consideration 
having the greater fair market value. 

Related Person Business Combination of Nichols. A "Related Person Business 
Combination" (as defined below) requires the affirmative vote of the holders 
of a majority of the shares of Class A Common Stock not owned by a "Related 
Person" (as defined below), voting as a separate class, unless both the Equal 
Consideration Requirement set forth above and the Fair Consideration 
Requirement referred to below are each satisfied, as to the Class A Common 
Stock. Likewise, a Related Business Combination requires the affirmative vote 
of the holders of a majority of the shares of Class C Common Stock not owned 
by a Related Person, voting as a separate class, unless both the Equal 
Consideration Requirement set forth above and the Fair Consideration 
Requirement referred to below are each satisfied as to the Class C Common 
Stock.
<PAGE>
<PAGE>
 
The "Fair Consideration Requirement" referred to above is satisfied as to the 
relevant class of stock (Class A Common Stock or Class C Common Stock) with 
respect to a Related Person Business Combination if both of the following 
conditions are satisfied as to that class of stock: 

  (i) The aggregate amount of cash plus the fair market value as of the date 
of the consummation of the Related Person Business Combination of any 
consideration other than cash to be received per share by holders of that 
class of stock is at least equal to the higher of the following: 

    (A) the highest per share price (including any brokerage commissions, 
transfer taxes and soliciting dealers' fees) paid or agreed to be paid by the 
Related Person for any shares of Class A Common Stock, Class B Common Stock 
or Class C Common Stock acquired by it (1) within the period of eighteen (18) 
months immediately prior to and including the date of the most recent public 
announcement of the proposal of the Related Person Business Combination (the 
"Announcement Date") or (2) in the transaction or series of transactions in 
which it became a Related Person; or 

    (B) the fair market value per share of Class A Common Stock or Class C 
Common Stock, whichever is higher, on the Announcement Date or on the date on 
which the Related Person became a Related Person (such latter date is 
referred to as the "Determination Date"), whichever is higher; and 

  (ii) The consideration to be received by holders of the relevant class of 
stock (Class A Common Stock or Class C Common Stock) is in cash or in the 
same form of consideration and in the same ratio of forms of consideration as 
the Related Person has previously paid for shares of any class or series of 
Class A Common Stock, Class B Common Stock or Class C Common Stock. If the 
Related Person has paid for shares of any such class with varying forms of 
consideration, the form of consideration for the relevant class of stock 
shall be (A) either all cash or the form or forms of consideration used to 
acquire the largest number of shares of such class of common stock previously 
acquired by the Related Person and (B) in the same ratio of forms of 
consideration used to acquire the largest number of shares of such class of 
common stock previously acquired by the Related Person. 

The Nichols Certificate of Incorporation defines a "Related Person" to mean, 
in general, any individual, corporation, partnership or other person or 
entity, or any group of two or more of the foregoing that have agreed to act 
together, which, together with its affiliates and associates, beneficially 
owns, in the aggregate, ten percent (10%) or more of any class of the 
outstanding shares of Class A Common Stock or Class B Common Stock, and any 
affiliate or associate of any such individual, corporation, partnership or 
other person or entity (excluding therefrom Dr. Albert Nichols). 

The Nichols Certificate of Incorporation defines a "Related Person Business 
Combination" to mean, in general (a) any merger, consolidation, combination 
or reorganization of Nichols or a subsidiary with or into a Related Person or 
of a Related Person with or into Nichols or a subsidiary, (b) any sale, 
lease, exchange, transfer, liquidation or other disposition, including 
without limitation, a mortgage or any other security device, of assets of 
Nichols and/or one or more subsidiaries (including without limitation, any 
voting securities of a subsidiary) constituting a substantial part of Nichols 
to a Related Person, (c) any sale, lease, exchange, transfer, liquidation or 
other disposition, including without limitation, a mortgage or any other 
security device, of assets of a Related Person (including without limitation, 
any voting securities of a subsidiary of such Related Person), to Nichols 
and/or one or more subsidiaries of the assets constitute a substantial part 
of such Related Person or the consideration of the assets from Nichols or the 
subsidiary or subsidiaries constitutes a substantial part of Nichols, (d) any 
recapitalization or reorganization that would have the effect, directly or 
indirectly, of increasing the voting power of a Related Person, and (e) any 
agreement, contract or other arrangement providing for any of the 
transactions described above as a Related Person Business Combination. 

The Nichols Board has determined that, with respect to the Merger, the Equal 
Consideration Requirement has been satisfied and that the Merger does not 
involve a Related Person and, therefore, the Fair Consideration Requirement 
does not apply. 

Under the New York Business Corporation Law (the "NYBCL"), the vote of the 
holders of two-thirds of all outstanding shares of stock of a New York 
corporation entitled to vote thereon is required for mergers and 
consolidations, and for sales, leases, exchanges or other dispositions of all 
or substantially all the assets of a corporation, if not made in the usual or 
regular course of the business actually conducted by such corporation. 

The Corning Certificate of Incorporation contains several provisions 
concerning business combinations and takeovers.
<PAGE>
<PAGE>
 
Corning's Fair Price Amendment 

In 1985, Corning's stockholders adopted the Fair Price Amendment which, in 
general, requires the approval by the holders of at least 80% of the voting 
power of the outstanding capital stock of Corning entitled to vote generally 
in the election of directors (the "Voting Stock") as a condition for mergers 
and certain other Business Combinations (as defined below) with any 
beneficial owner of more than 10% of such voting power (an "Interested 
Shareholder") unless (i) the transaction is approved by at least a majority 
of the Continuing Directors (as defined below) or (ii) certain minimum price, 
form of consideration and procedural requirements are met. 

Amendment or repeal of this provision or the adoption of any provision 
inconsistent therewith would require the affirmative vote of at least 80% of 
the Voting Stock unless the proposed amendment or repeal or the adoption of 
the inconsistent provision was approved by two-thirds of the entire Corning 
Board and a majority of the Continuing Directors. 

An Interested Shareholder is, in general, defined in the Fair Price Amendment 
as any person or group who is, or was at any time within the two-year period 
immediately prior to the date in question, the beneficial owner of more than 
10% of the voting power of the Voting Stock. The term "beneficial owner" 
includes persons directly or indirectly owning or having the right to acquire 
or vote the shares. In certain circumstances, an Interested Shareholder could 
include persons or entities affiliated or associated with the Interested 
Shareholder. 

A Business Combination in general includes the following transactions: (i) a 
merger or consolidation of Corning or any subsidiary with an Interested 
Shareholder; (ii) the sale or other disposition by Corning or a subsidiary of 
assets having an aggregate fair market value of $20,000,000 or more if an 
Interested Shareholder is a party to the transaction; (iii) the issuance or 
transfer of stock or other securities of Corning or of a subsidiary to an 
Interested Shareholder in exchange for cash or property (including stock or 
other securities) having an aggregate fair market value of $20,000,000 or 
more; (iv) the adoption of any plan or proposal for the liquidation or 
dissolution of Corning proposed by or on behalf of an Interested Shareholder; 
(v) any reclassification of securities, recapitalization, merger or 
consolidation with a subsidiary or other transaction which has the effect, 
directly or indirectly, of increasing the percentage of the outstanding stock 
of any class of Corning or a subsidiary owned by an Interested Shareholder; 
or (vi) any agreement, contract or other arrangement providing for any one or 
more of the foregoing actions. 

A Continuing Director is in general (i) any member of the Board who is not an 
Interested Shareholder or affiliated or associated with an Interested 
Shareholder and was a director of Corning prior to the time the Interested 
Shareholder became an Interested Shareholder, and any successor to such a 
Continuing Director who is not affiliated or associated with an Interested 
Shareholder and was recommended or elected by a majority of the Continuing 
Directors then on the Board, or (ii) any person who was elected to the Board 
at Corning's 1985 Annual Meeting of Shareholders and any successor thereto 
who was recommended or elected by a Majority of the Continuing Directors then 
on the Board. It is possible that the approval of a majority of the 
Continuing Directors could be obtained in accordance with the Fair Price 
Amendment in circumstances where the Continuing Directors constitute less 
than a quorum of the entire Board. 

The 80% affirmative stockholder vote would not be required if the Business 
Combination in question had been approved by a majority of the Continuing 
Directors or if all the minimum price, form of consideration and procedural 
requirements described below are satisfied. 

Minimum Price and Form of Consideration Requirements. In a Business 
Combination involving cash or other consideration being paid to Corning's 
stockholders, the consideration required, in the case of each class of Voting 
Stock, would be either cash or the same type of consideration used by the 
Interested Shareholder in acquiring the largest portion of its shares of that 
class of Voting Stock prior to the first public announcement of the proposed 
Business Combination. In addition, the fair market value (as calculated in 
accordance with the Fair Price Amendment) of such consideration would be 
required to meet the minimum price requirements described below. 

In the case of payments to holders of Corning's Common Stock, the fair market 
value per share of such payments would have to be at least equal in value to 
the higher of (i) the highest per share price paid by the Interested 
Shareholder in acquiring any shares of Corning's Common Stock during the two 
years prior to the first public announcement of the proposed Business 
Combination (the "Announcement Date") or in the transaction in which it 
became an Interested Shareholder, whichever is higher, and (ii) the fair 
market value per share of Common Stock on the announcement date or on the 
date on which the Interested Shareholder became an Interested Shareholder, 
whichever is higher. 

In the case of payments to holders of any series of Corning's voting Series 
Preferred Stock, if any, the fair market value per share of such payments 
would have to be at least equal to the higher of (i) the price per share
<PAGE>
<PAGE>
 
determined with respect to shares of such series in the same manner as 
described in the preceding paragraph with respect to shares of Common Stock 
and (ii) the highest preferential amount per share to which the holders of 
such series of Series Preferred Stock "are entitled in the event of a 
voluntary or involuntary liquidation of Corning." 

If the transaction does not involve any cash or other property being received 
by any of the other stockholders, such as a sale of assets or an issuance of 
Corning's securities to an Interested Shareholder, then the minimum price, 
form of consideration and procedural requirements would not apply, but an 80% 
vote of stockholders would still be required unless the transaction was 
approved by a majority of the Continuing Directors. 

Procedural Requirements. An 80% stockholder vote would be required to 
authorize a Business Combination with an Interested Shareholder if Corning, 
after the Interested Shareholder became an Interested Shareholder, had failed 
to pay full quarterly dividends on its Preferred Stock, if any, or reduced 
the rate of dividends paid on its Common Stock, unless such failure or 
reduction was approved by a majority of the Continuing Directors. 

The Fair Price Amendment would also require an 80% stockholder vote to 
authorize a Business Combination with an Interested Shareholder if the 
Interested Shareholder had acquired any additional shares of the Voting 
Stock, directly from Corning or otherwise, in any transaction subsequent to 
the transaction pursuant to which it became an Interested Shareholder. 

The receipt by the Interested Shareholder at any time after it became an 
Interested Shareholder, whether in connection with the proposed Business 
Combination or otherwise, of the benefit of any loans or other financial 
assistance or tax advantages provided by Corning (other than proportionately 
as a stockholder) would also trigger the 80% stockholder vote requirement to 
authorize a Business Combination with an Interested Shareholder (unless the 
Business Combination was approved by a majority of the Continuing Directors). 

Finally, the 80% stockholder vote requirement to authorize a Business 
Combination with an Interested Shareholder would apply unless a proxy or 
information statement disclosing the terms and conditions of the proposed 
Business Combination complying with the requirements of the proxy rules 
promulgated under the Securities Exchange Act of 1934, as amended, was mailed 
to all Corning stockholders at least 45 days prior to the consummation of a 
Business Combination, unless the Business Combination was approved by a 
majority of the Continuing Directors. 

In summary, none of the minimum price, form of consideration or procedural 
requirements described above would apply in the case of a Business 
Combination approved by a majority of the Continuing Directors. In the 
absence of such approval, all of such requirements would have to be satisfied 
to avoid the 80% stockholder vote requirements. 

Certain Other Provisions of Corning's Restated Certificate and By-Laws 

In addition to the Fair Price Amendment, Corning's Restated Certificate and 
By-Laws contain other provisions that may discourage a third party from 
seeking to acquire Corning or to commence a proxy contest or other 
takeover-related action. Corning has classified its Board of Directors such 
that one-third of the Board is elected each year to a three-year term of 
office. In addition, holders of Corning Common Shares may remove a director 
from office at any time prior to the expiration of his or her term only with 
cause and by vote of a majority of Corning Common Shares outstanding. These 
provisions, together with provisions concerning the size of the Corning Board 
and requiring that premature vacancies on the Board be filled only by a 
majority of the entire Board, may not be amended, altered or repealed, nor 
may Corning adopt any provision inconsistent therewith, without the 
affirmative vote of at least 80% of the Voting Stock of Corning or the 
approval of two-thirds of the entire Corning Board of Directors. 

Corning has a Preferred Share Purchase Rights plan which could have a 
deterrent effect on parties seeking to acquire large quantities of Corning 
Common Shares without the approval of the Corning Board. See "DESCRIPTION OF 
CORNING CAPITAL STOCK--Preferred Share Purchase Rights". 

Corning's By-Laws contain certain procedural requirements with respect to the 
nomination of directors by stockholders that require, among other things, 
delivery of notice by such stockholders to the Secretary of Corning not later 
than 60 days prior to the date of the stockholders' meeting at which such 
nomination is to be considered. Corning's By-Laws do not provide that a 
meeting of the Corning Board may be called by stockholders. 

The effect of these provisions may be to deter attempts either to obtain 
control of Corning or to acquire a substantial amount of its stock, even if 
such a proposed transaction was at a significant premium over the 
then-prevailing market value of Corning Common Shares, or to deter attempts 
to remove the Corning Board and the management of Corning, even though some 
or a majority of the holders of Corning Common Shares may believe such 
actions to be beneficial.

Appraisal Rights 
Under the DGCL, except as otherwise provided by the DGCL, stockholders have 
the right to demand and receive payment of the fair value of their stock in 
the event of a merger or consolidation. However, except as otherwise provided 
by the DGCL, stockholders do not have appraisal rights if, among other 
things, the consideration they receive for their shares consists of (i) 
shares of stock of the corporation surviving or resulting from such merger or 
consolidation, (ii) shares of stock of any other corporation which at the 
effective date of the merger or consolidation will be either listed on a 
national securities exchange (which is true in the case of the Corning Common 
Shares) or designated as a national market system security on an inter-dealer 
quotation system by the National Association of Securities Dealers, Inc. or 
held of record by more than 2,000 stockholders, (iii) cash in lieu of 
fractional shares of the corporations described in clause (i) or (ii) of this 
sentence, or (iv) any combination of shares of stock and cash in lieu of 
fractional shares described in the foregoing clauses (i), (ii) and (iii). See 
"THE MERGER--Appraisal Rights for Unlisted Stock Only." 

Stockholders of a New York corporation have the right to dissent and receive 
payment of the fair value of their shares, except as otherwise provided by 
the NYBCL, in the event of certain amendments or changes to the certificate 
of incorporation adversely affecting their shares, certain mergers or 
consolidations, certain sales, leases, exchanges or other dispositions of all 
or substantially all the corporation's assets and certain share exchanges. 

State Takeover Legislation 
Delaware Business Combination Law. Section 203 of the DGCL (the "Delaware 
Business Combination Law") generally prohibits any business combination 
(defined to include a variety of transactions, including (i) mergers and 
consolidations, (ii) sales or dispositions of assets having an aggregate 
market value equal to 10% or more of the aggregate market value of the 
corporation determined on a consolidated basis, (iii) issuances of stock 
(except for certain pro rata and other issuances) and (iv) disproportionate 
benefits from the corporation (including loans and guarantees) between a 
Delaware corporation and any interested stockholder (defined generally as any 
person who, directly or indirectly, beneficially owns 15% or more of the 
outstanding voting stock of the corporation (including a person who has an 
agreement or understanding for the voting of such stock with a person who 
beneficially owns 15% or more of such voting stock)) for a period of three 
years after the date on which the interested stockholder became an interested 
stockholder. The restrictions of the Delaware Business Combination Law do not 
apply, however, (A) if, prior to such date, the board of directors of the 
corporation approved either the business combination or the transaction which 
resulted in such stockholder's becoming an interested stockholder, (B) if, 
upon consummation of the transaction resulting in such stockholder's becoming 
an interested stockholder, the interested stockholder owned at least 85% of 
the voting stock of the corporation at the time the transaction was commenced 
(excluding, for the purposes of determining the number of shares outstanding, 
shares owned by persons who are directors and also officers and by certain 
employee plans of the corporation), (C) if, on or subsequent to such date, 
the business combination is approved by the board of directors and the 
holders of at least two-thirds of the shares not involved in the transaction 
or (D) under certain other circumstances. 

In addition, a Delaware corporation may adopt an amendment to its certificate 
of incorporation or by-laws expressly electing not to be governed by the 
Delaware Business Combination Law if, in addition to any other vote required 
by law, such amendment is approved by the affirmative vote of a majority of 
the shares entitled to vote. Such amendment will not, however, be effective 
until 12 months after such stockholder vote and will not apply to any 
business combination with an interested stockholder who was such on or prior 
to the effective date of such amendment. Nichols has not amended the Nichols 
By-Laws to elect not to be governed by the Delaware Business Combination Law. 
The Nichols Board, however, has approved the Merger and the Dr. Nichols 
Letter Agreement and, as a result, the restrictions of the Delaware Business 
Combination Law do not apply to the Merger. See "THE MERGER--Agreement of Dr. 
Nichols to Vote in Favor of the Merger". 

New York Business Combination Law. Section 912 of the NYBCL (the "New York 
Business Combination Law") prohibits any business combination (defined to 
include a variety of transactions, including mergers, sales or dispositions 
of assets, issuances of stock, liquidations, reclassifications and benefits 
from the corporation, including loans or guarantees) with, involving or 
proposed by any interested stockholder (defined generally as any person who, 
directly or indirectly, beneficially owns 20% or more of the outstanding 
voting stock of a resident domestic New York corporation) for a period of 
five years after the date on which the interested stockholder became an 
interested stockholder. After such five-year period a business combination 
between a resident domestic New York corporation and such interested 
stockholder is prohibited unless either certain "fair price" provisions are 
complied with or the business combination is approved by a majority of the 
outstanding voting stock not beneficially owned by such interested 
stockholder or its affiliates. The New York Business Combination Law exempts 
from its prohibitions any business combination with an interested stockholder 
if such business combination, or the purchase of stock by the interested 
stockholder that caused such stockholder to become such, is approved by the 
board of directors
<PAGE>
<PAGE>
 
of the resident domestic New York corporation prior to the date on which the 
interested stockholder becomes such. Corning will be considered a resident 
domestic New York corporation as long as at least 10% of its voting stock is 
owned beneficially by residents of (or organizations having their principal 
offices in) the State of New York. 

A resident domestic New York corporation may adopt an amendment to its 
by-laws, approved by the affirmative vote of the holders, other than 
interested stockholders and their affiliates and associates, of a majority of 
the outstanding voting stock, excluding the voting stock of interested 
stockholders and their affiliates and associates, expressly electing not to 
be governed by the New York Business Combination Law. However, such amendment 
will not be effective until 18 months after such stockholder vote and will 
not apply to any business combination with an interested stockholder who was 
such on or prior to the effective date of such amendment. Corning has not 
amended the Corning By-Laws to elect not to be governed by the New York 
Business Combination Law. 

Stockholder Rights Plan 
Corning has a Preferred Share Purchase Rights plan which could have a 
deterrent effect on parties seeking to acquire large quantities of Corning 
Common Shares without the approval of the Corning Board. See "DESCRIPTION OF 
CORNING CAPITAL STOCK--Preferred Share Purchase Rights." 

Amendments to Charters 
Under the DGCL, unless otherwise provided in the charter, a proposed charter 
amendment requires an affirmative vote of a majority of all votes entitled to 
be cast on the matter. If any such amendment would adversely affect the 
rights of any holders of shares of a class or series of stock, the vote of 
the holders of a majority of all outstanding shares of the class or series, 
voting as a class, is also necessary to authorize such amendment. The DGCL 
requires an affirmative vote of a majority of the total number of shares 
outstanding and entitled to vote thereon to amend the Nichols Certificate of 
Incorporation. The Nichols Certificate of Incorporation provides that it may 
be amended, at any time, in the manner prescribed by the DGCL. 

Under the NYBCL, amendments of the certificate of incorporation may be 
authorized by vote of the holders of a majority of all outstanding shares 
entitled to vote thereon at a meeting of stockholders. If any such amendment 
would adversely affect the rights of any holders of shares of a class or 
series of stock, the vote of the holders of a majority of all outstanding 
shares of the class or series, voting as a class, is also necessary to 
authorize such amendment. Pursuant to the Merger Agreement, Corning has 
agreed that, prior to the Closing or earlier termination of the Merger 
Agreement, it will not adopt any amendments to the Corning Certificate of 
Incorporation in a manner which could reasonably be expected to be materially 
adverse to the shareholders of Nichols. See "THE MERGER--Certain 
Covenants--Conduct of Business by Corning." 

Amendments to By-Laws 
Under the DGCL, the power to adopt, alter and repeal the by-laws is vested in 
the stockholders, except to the extent that the charter or the by-laws vest 
it in the board of directors. 

The Nichols By-Laws may be amended or repealed by either the affirmative vote 
of the stockholders at an annual meeting, without previous notice, or at a 
special meeting, with notice of the proposed amendment or repeal, or by the 
vote of a majority of the directors then in office, acting at any meeting of 
the Nichols Board. 

Under the NYBCL, except as otherwise provided in the certificate of 
incorporation, by-laws may be amended, repealed or adopted by vote of the 
holders of the shares at the time entitled to vote in the election of any 
directors. When so provided in the certificate of incorporation or a by-law 
adopted by the stockholders, by-laws also may be amended, repealed or adopted 
by the board by such vote as may be therein specified, which may be greater 
than the vote otherwise prescribed by law, but any by-law adopted by the 
board may be amended or repealed by the stockholders entitled to vote thereon 
as provided by the NYBCL. 

The Corning By-Laws may be amended or repealed by either the affirmative vote 
of the holders of record of a majority in number of the outstanding shares of 
stock entitled to vote or by the vote of a majority of the whole Board of 
Directors, except that any amendment to or repeal of certain provisions of 
the By-Laws (relating to, among other things, the number, election, term, and 
general powers of directors, as well as the amendment or repeal of such 
provisions, must be approved by an affirmative vote of the holders of record 
of outstanding shares representing at least 80% of the voting power of all 
the outstanding shares of capital stock of Corning entitled to vote generally 
in the election of directors. 

Preemptive Rights 
Under the DGCL, a stockholder does not possess preemptive rights unless such 
rights are specifically granted in the certificate of incorporation. The 
Nichols Certificate of Incorporation does not provide for preemptive rights.
<PAGE>
<PAGE>
 
Under the NYBCL, except as otherwise provided in the NYBCL or in the 
certificate of incorporation, the holders of equity shares are granted 
certain preemptive rights. The Corning Certificate of Incorporation provides 
that no holder of Corning Common Shares or Series Preferred Stock has any 
preemptive rights to purchase any shares or other securities of Corning. 

Redemption of Capital Stock 
Under the DGCL, subject to certain limitations, a corporation's stock may be 
made subject to redemption by the corporation at its option, at the option of 
the holders of such stock or upon the happening of a specified event. Nichols 
may, at its option and at the direction of the Nichols Board, redeem at any 
time, in whole or in part, the outstanding shares of the Nichols Preferred 
Stock from any source of funds legally available therefor. The redemption 
price for each share of Nichols Preferred Stock shall be $350 plus an amount 
equal to all dividends on shares, accrued and unpaid, whether or not earned 
or declared, to and including the date for redemption. See "DESCRIPTIONS OF 
NICHOLS CAPITAL STOCK--Preferred Stock". 

Under the NYBCL, subject to certain limitations, a corporation's certificate 
of incorporation may provide for one or more classes or series of shares to 
be redeemable at the option of the corporation or the holders thereof, at 
such prices, within such times and under such conditions as are stated in the 
certificate of incorporation. Corning's Certificate of Incorporation provides 
for the issuance of redeemable securities and Corning has issued redeemable 
preferred stock. See "DESCRIPTION OF CORNING CAPITAL STOCK--Series B 
Preferred Stock" and "--Series C Preferred Stock". 

Dividend Sources 
Under the DGCL, a board of directors may authorize a corporation to make 
distributions to its stockholders, subject to any restrictions in its 
certificate of incorporation, either (i) out of surplus or (ii) if there is 
no surplus, out of net profits for the fiscal year in which the dividend is 
declared and/or the preceding fiscal year. Under the DGCL, no distribution 
out of net profits is permitted, however, if the corporation's capital is 
less than the amount of capital represented by the issued and outstanding 
stock of all classes having a preference upon the distribution of assets, 
until such deficiency has been repaired. 

Under the NYBCL, except as otherwise provided in the NYBCL, dividends may be 
declared and paid and other distributions may be made out of surplus only, so 
that the net assets of the corporation remaining after such declaration, 
payment or distribution must at least equal the amount of its stated capital. 
A corporation may declare and pay dividends or make other distributions, 
except when the corporation is insolvent or would thereby be made insolvent, 
or when the declaration, payment or distribution would be contrary to any 
restrictions contained in the corporation's certificate of incorporation. 

Duration of Proxies 
Under the DGCL and the Nichols By-Laws, no proxy is valid more than three 
years after its date unless otherwise provided in the proxy. 

Under the NYBCL, no proxy is valid more than 11 months after its date unless 
otherwise provided in the proxy. Irrevocable proxies may be created for (i) a 
pledgee, (ii) a person who has purchased or agreed to purchase the shares, 
(iii) a creditor of the corporation who extends credit in consideration of 
the proxy, (iv) a person who has contracted to perform services as an officer 
of the corporation if a proxy is required by the employment contract and (v) 
a person designated under a voting agreement. 

Stockholder Action 
Under the DGCL, unless otherwise provided in the certificate of 
incorporation, any action required or permitted to be taken at a meeting of 
stockholders may be taken without a meeting, without prior notice and without 
a vote, if a written consent or consents setting forth the action taken is 
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 upon such action were present 
and voted. The Nichols By-Laws permit stockholder action to be taken by a 
majority written consent. 

Under the NYBCL, any action required or permitted to be taken by vote may be 
taken without a meeting by written consent or consents, setting forth the 
action taken and signed by the holders of all outstanding shares entitled to 
vote thereon, provided that the certificate of incorporation may contain a 
provision requiring the written consent of the holders of less than all 
outstanding shares. The Corning Certificate of Incorportion does not contain 
such a provision and, accordingly, the Corning shareholders may act without a 
meeting only by unanimous written consent.

Special Stockholder Meetings 
The DGCL provides that a special meeting of stockholders may be called by the 
board of directors or by such person or persons as may be authorized by the 
certificate of incorporation or by the by-laws. The Nichols By-Laws provide 
that special meetings may be called by the Board or by the President. 

The Corning By-Laws provide that special meetings of the stockholders may be 
called at any time by the Chairman of the Board, the Chairman of the 
Executive Committee, a Vice Chairman or the President and shall be called by 
the Secretary or an Assistant Secretary upon order of the Corning Board, the 
Chairman of the Corning Board a majority of the Corning directors. In 
addition, the NYBCL provides that if, for a period of one month after the 
date fixed by or under the by-laws for the annual meeting of stockholders or, 
if no date has been so fixed, for a period of 13 months after the last annual 
meeting, there is a failure to elect a sufficient number of directors to 
conduct the business of the corporation, the board shall call a special 
meeting for the election of directors. If such special meeting is not called 
by the board within two weeks after the expiration of such period or if it is 
called but there is a failure to elect such directors for a period of two 
months after the expiration of such period, holders of 10% of the shares 
entitled to vote in an election of directors may, in writing, demand the call 
of a special meeting for the election of directors. 

Cumulative Voting 
The DGCL permits cumulative voting. The Nichols By-Laws provide that at all 
elections of directors of Nichols a holder of any class or series of stock 
then entitled to vote in such election shall be entitled to as many votes as 
shall equal the number of votes which (but for such provision as to 
cumulative voting) he would be entitled to cast for the election of directors 
with respect to his shares of stock multiplied by the number of directors to 
be elected in the election in which his class or series of stock is entitled 
to vote, and each stockholder may cast all of such votes for a single nominee 
for director or may distribute them among the number to be voted for, or for 
any two or more of them as he may see fit. 

Under the NYBCL, the certificate of incorporation may provide that in all 
elections of directors each stockholder is entitled to cumulate such 
stockholder's votes. The Corning Certificate of Incorporation does not 
contain such a provision. 

Number and Election of Directors 
The DGCL permits the certificate of incorporation or the by-laws of a 
corporation to contain provisions governing the number and terms of 
directors. However, if the certificate of incorporation contains provisions 
fixing the number of directors, such number may not be changed without 
amending the certificate of incorporation. The Nichols By-Laws provide that 
the number of directors of Nichols shall be not less than five nor more than 
nine, until changed in accordance with applicable law. The exact number of 
directors shall be fixed from time to time, within the limit specified, by 
resolution of the Nichols Board or the stockholders. Subject to the foregoing 
provisions for changing the exact number of directors, the number of 
directors has been fixed at eight. Each of the directors of Nichols shall 
hold office until his successor shall have been duly elected and shall 
qualify or until he shall resign or shall have been removed in the manner 
hereinafter provided. 

The DGCL permits the certificate of incorporation of a corporation or a 
by-law adopted by the stockholders to provide that directors be divided into 
one, two or three classes. The term of office of one class of directors shall 
expire each year with the terms of office of no two classes expiring the same 
year. Nichols does not have a classified board of directors. 

Subject to certain limitations, the NYBCL permits the number of directors of 
a corporation to be fixed by its by-laws, by action of the stockholders or by 
action of the board under the specific provision of a by-law adopted by the 
stockholders. At each annual meeting of the stockholders, directors are to be 
elected to hold office until the next annual meeting, except as described 
below for corporations with classified boards. The Corning Certificate of 
Incorporation provides that the number of directors shall be 21 unless 
otherwise determined by a resolution adopted by a majority of the entire 
Board of Directors, but in no instance shall the number be less than nine nor 
more than 24 persons. 

The NYBCL permits the certificate of incorporation or the specific provisions 
of a by-law adopted by the stockholders to provide that directors be divided 
into either two, three or four classes. All classes must be as nearly equal 
in number as possible, and no class may include less than three directors. 
The term of office of one class of directors shall expire each year with the 
terms of office of no two classes expiring the same year. Corning's 
Certificate of Incorporation provides for three classes of directors each to 
be elected for terms of three years with each class consisting of as nearly 
an equal number of directors as possible.

<PAGE>
 
Removal of Directors 
The DGCL provides that a director or directors may be removed with or without 
cause by the holders of a majority of the shares then entitled to vote at an 
election of directors, except that (i) members of a classified board may be 
removed only for cause, unless the certificate of incorporation provides 
otherwise and (ii) in the case of a corporation having cumulative voting, if 
less than the entire board is to be removed, no director may be removed 
without cause if the votes cast against such director's removal would be 
sufficient to elect such director if then cumulatively voted at an election 
of the entire board of directors or of the class of directors of which such 
director is a part. 

The Nichols Certificate of Incorporation provides that the holders of Class A 
Common Stock will be entitled to vote as a separate class on the removal, 
with or without cause, of any director elected by the holders of Class A 
Common Stock, provided that, to the extent permitted by applicable law, any 
director may be removed for cause by the Nichols Board. 

The Nichols Certificate of Incorporation provides further that the holders of 
the Class B Common Stock (subject to voting rights that may be granted to 
holders of Nichols Preferred Stock outstanding from time to time) will be 
entitled to vote as a separate class on the removal, with or without cause, 
of any director who was elected either by the holders of the Class B Common 
Stock or by directors who were elected by the holders of the Class B Common 
Stock, provided that any director may be removed for cause by the Nichols 
Board. 

The Nichols By-Laws provide that, subject to the provisions of the Nichols 
Certificate of Incorporation, any director may be removed at any time, either 
with or without cause, by the affirmative vote of the stockholders having a 
majority of the voting power of Nichols given at a special meeting of the 
stockholders called for the purpose, except that no director may be removed 
without cause (unless the entire Nichols Board is removed) if the votes cast 
against his removal would be sufficient to elect him if then cumulatively 
voted at an election of the entire Nichols Board. 

The NYBCL provides that any or all of the directors may be removed for cause 
by vote of the stockholders and, if the certificate of incorporation or the 
specific provisions of a by-law adopted by the stockholders provide, 
directors may be removed by action of the board of directors. If the 
certificate of incorporation or the by-laws so provide, any or all of the 
directors may be removed without cause by vote of the stockholders. The 
removal of directors, with or without cause, is subject to the following: (i) 
in the case of a corporation having cumulative voting, no director may be 
removed when the votes cast against such director's removal would be 
sufficient to elect the director if voted cumulatively and (ii) if a director 
is elected by the holders of shares of any class or series, such director may 
be removed only by the applicable vote of the holders of the shares of that 
class or series voting as a class. An action to procure a judgment removing a 
director for cause may be brought by the attorney general or by the holders 
of 10% of the outstanding shares, whether or not entitled to vote. 

The Corning Certificate of Incorporation provides for the removal of 
directors by an affirmative vote of the holders of record of outstanding 
shares representing a majority of the voting power of all of the outstanding 
shares of capital stock entitled to vote generally in the election of 
directors or by the affirmative vote of a majority of the entire Board of 
Directors, but, in either case, only for cause. 

Vacancies 
Under the DGCL, unless otherwise provided in the certificate of incorporation 
or the by-laws, vacancies on the board of directors and newly created 
directorships resulting from an increase in the authorized number of 
directors may be filled by a majority of the directors then in office, 
although less than a quorum, or by the sole remaining director, provided 
that, in the case of a classified board, such vacancies and newly created 
directorships may be filled by a majority of the directors elected by such 
class, or by the sole remaining director so elected. In the case of a 
classified board, directors elected to fill vacancies or newly created 
directorships shall hold office until the next election of the class for 
which such directors have been chosen and until their successors have been 
duly elected and qualified. In addition, if, at the time of the filling of 
any such vacancy or newly created directorship, the directors in office 
constitute less than a majority of the whole board (as constituted 
immediately prior to any such increase), the Delaware Court of Chancery may, 
upon application of any stockholder or stockholders holding at least 10% of 
the total number of outstanding shares entitled to vote for such directors, 
summarily order an election to fill any such vacancy or newly created 
directorship, or replace the directors chosen by the directors then in 
office. 

The Nichols Certificate of Incorporation provides that any vacancy in the 
office of a director elected by the holders of Class A Common Stock may be 
filled by a vote of such holders voting as a separate class and, in the 
absence of a stockholder vote, such vacancy may be filled by the remaining 
directors who were elected either by the holders of the Class A Common Stock 
or by directors who were elected by the holders of the Class A Common
<PAGE>
<PAGE>
 
Stock or, if no such directors are then in office, the remaining directors 
regardless of how they were elected. Any director elected by the Nichols 
Board to fill a vacancy shall serve until the next annual meeting of 
stockholders and until his successor has been elected and has qualified. If 
permitted by the Nichols By-Laws, the Nichols Board may increase the number 
of directors and any vacancy so created may be filled by the Nichols Board; 
provided that unless certain conditions exist in respect of the next previous 
annual meeting of stockholders the Nichols Board may be so enlarged by the 
Nichols Board only to the extent that 25% of the enlarged Nichols Board 
consists of directors elected by the holders of the Class A Common Stock or 
by persons appointed to fill vacancies created by the death, resignation or 
removal of persons elected by the holders of the Class A Common Stock. 

The Nichols Certificate of Incorporation provides further that any vacancy in 
the office of a director elected by the holders of Class B Common Stock may 
be filled by a vote of such holders voting as a separate class (subject to 
voting rights that may be granted to holders of Nichols Preferred Stock 
outstanding from time to time) and in the absence of a stockholder vote, such 
vacancy may be filled by the remaining directors who were elected either by 
the holders of the Class B Common Stock or by the directors who were elected 
by the holders of the Class B Common Stock or, if no such directors are then 
in office, the remaining directors regardless of how they were elected. 

The Nichols By-Laws provide that, except as otherwise provided in the Nichols 
Certificate of Incorporation, any vacancy in the Nichols Board, whether 
because of death, resignation, disqualification, an increase in the number of 
directors, or any other cause, may be filled by vote of the majority of the 
remaining directors, although less than a quorum. Each director so chosen to 
fill a vacancy shall hold office until his successor shall have been elected 
and shall qualify or until he shall resign or shall have been removed in the 
manner hereinafter provided. 

Under the NYBCL, newly created directorships resulting from an increase in 
the number of directors and vacancies occurring on the board for any reason 
except the removal of directors without cause may be filled by vote of the 
board of directors. However, the certificate of incorporation or by-laws may 
provide that such newly created directorships or vacancies are to be filled 
by vote of the stockholders. Unless the certificate of incorporation or the 
specific provisions of a by-law adopted by the stockholders provide that the 
board may fill vacancies occurring on the board by reason of the removal of 
directors without cause, such vacancies may be filled only by vote of the 
stockholders. A director elected to fill a vacancy, unless elected by the 
stockholders, will hold office until the next meeting of stockholders at 
which the election of directors is in the regular order of business and until 
his or her successor has been elected and qualified. 

The Corning Certificate of Incorporation does not provide for the removal of 
directors without cause. The Corning Certificate of Incorporation provides 
that any vacancy on the Corning Board other than a vacancy created by the 
expiration of a director's regular term will be filled by a majority vote of 
the remaining directors. 

Indemnification of Directors and Officers 
Under the DGCL, a corporation may not indemnify any director, officer, 
employee or agent made or threatened to be made party to any threatened, 
pending or completed proceeding unless such person acted in good faith and in 
a manner such person reasonably believed to be in or not opposed to the best 
interests of the corporation, and, with respect to any criminal proceeding, 
had no reasonable cause to believe that his or her conduct was unlawful. The 
Nichols By-Laws contain provisions which require Nichols to indemnify such 
persons to the full extent permitted by the DGCL. 

The DGCL also establishes several mandatory rules for indemnification. In the 
case of a proceeding by or in the right of the corporation to procure a 
judgment in its favor (e.g., a stockholder derivative suit), a corporation 
may indemnify an officer, director, employee or agent if such person acted in 
good faith and in a manner such person reasonably believed to be in or not 
opposed to the best interests of the corporation; provided, however, that no 
person adjudged to be liable to the corporation may be indemnified unless, 
and only to the extent that, the Delaware Court of Chancery or the court in 
which such action or suit was brought determines upon application that, 
despite the adjudication of liability but in view of all the circumstances of 
the case, such person is fairly and reasonably entitled to indemnity for such 
expenses which such court deems proper. A director, officer, employee or 
agent who is successful, on the merits or otherwise, in defense of any 
proceeding subject to the DGCL's indemnification provisions must be 
indemnified by the corporation for reasonable expenses incurred therein, 
including attorneys' fees. 

The DGCL and the Nichols By-Laws state that a determination must be made that 
a director or officer has met the required standard of conduct before the 
director or officer may be indemnified. The determination may be made by (i) 
a majority vote of a quorum of disinterested directors, (ii) independent 
legal counsel (selected by the disinterested directors) or (iii) the 
stockholders. 

The DGCL and the Nichols By-Laws require Nichols to advance reasonable 
expenses to a director or officer after such person provides an undertaking 
to repay the corporation if it is determined that the required standard of 
conduct has not been met. In addition, the Nichols By-Laws permit Nichols to 
advance expenses to other employees and agents in a similar manner.
<PAGE>
<PAGE>
 
The indemnification and advancement of expenses described above under the 
DGCL is not exclusive of any other rights to which those seeking 
indemnification or advancement of expenses may be entitled under any by-law, 
agreement, vote of stockholders or disinterested directors or otherwise. 
Nichols has entered into indemnification agreements with certain of its 
officers and directors which provide that indemnification and advancement of 
expenses will be available to such persons regardless of any amendment to or 
revocation of the indemnification provisions contained in the Nichols 
By-Laws. 

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

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

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

The Corning By-Laws provide that Corning shall, to the full extent authorized 
or permitted by law, indemnify any person who is or was a director or officer 
of Corning, or any person who is or was serving as an officer or director of 
any other corporation, joint venture, trust, employee benefit plan or other 
enterprise in which Corning has a financial interest as an investor or 
creditor, and such person is serving or did serve at the express request of 
Corning. 

Insofar as indemnification for liabilities arising under the Securities Act 
may be permitted to directors, officers or persons controlling Corning or 
Nichols pursuant to the foregoing provisions, Corning and Nichols have been 
informed that in the opinion of the Commission such indemnification is 
against public policy as expressed in the Securities Act and is therefore 
unenforceable. 

Limitation of Personal Liability of Directors 
The DGCL provides that a corporation's certificate of incorporation may 
include a provision limiting the personal liability of a director to the 
corporation or its stockholders for monetary damages for breach of fiduciary 
duty as a director. However, no such provision can eliminate or limit the 
liability of a director for (i) any breach of the director's duty of loyalty 
to the corporation or its stockholders, (ii) acts or omissions not in good 
faith or which involve intentional misconduct or a knowing violation of the 
law, (iii) violation of certain provisions of the DGCL, (iv) any transaction 
from which the director derived an improper personal benefit or (v) any act 
or omission prior to the adoption of such a provision in the certificate of 
incorporation. The Nichols Certificate of Incorporation contains a provision 
eliminating the personal liability for monetary damages of its directors to 
the full extent permitted under Delaware law. 

The NYBCL provides that a corporation's certificate of incorporation may 
contain a provision eliminating or limiting the personal liability of 
directors to the corporation or its stockholders for damages for any breach 
of duty
<PAGE>
<PAGE>
 
in such capacity. However, no such provision can eliminate or limit the 
liability of any director (i) if a judgment or other final adjudication 
adverse to such director establishes that such director's acts or omissions 
were in bad faith, or involved intentional misconduct or a knowing violation 
of law, or that the director personally gained in fact a financial profit or 
other advantage to which such director was not legally entitled or that the 
director's acts violated certain provisions of the NYBCL or (ii) for any act 
or omission prior to the adoption of such a provision in the certificate of 
incorporation. 

The Corning Certificate of Incorporation provides that its directors shall 
not be liable to Corning or its stockholders for damages for any breach of 
duty as a director, except to the extent that such exemption from liability 
or limitation thereof is not permitted under the NYBCL. 

                                LEGAL OPINIONS 

The legality of the Corning Common Shares to be issued in connection with the 
Merger is being passed upon for Corning by William C. Ughetta, Senior Vice 
President and General Counsel of Corning. As of July 27, 1994, Mr. Ughetta 
owned substantially less than 1% of the outstanding Corning Common Shares 
(including shares subject to options). 

Certain of the tax consequences of the Merger to Nichols stockholders will be 
passed upon at the Effective Time, as a condition to the Merger, by Fulbright 
& Jaworski L.L.P., on behalf of Nichols. See "THE MERGER--Certain Federal 
Income Tax Consequences". Attorneys with the firm of Fulbright & Jaworski 
L.L.P. participating in the representation of Nichols in the Merger did not 
own any shares of Nichols Common Stock and owned 1,100 Corning Common Shares 
as of July 27, 1994.

INDEPENDENT AUDITORS' REPORT 

To the Board of Directors and Stockholders of 
Nichols Institute: 

We have audited the accompanying consolidated balance sheets of Nichols 
Institute and its subsidiaries (the Company) as of December 31, 1992 and 
1993, and the related consolidated statements of operations, stockholders' 
equity and cash flows for each of the three years in the period ended 
December 31, 1993. These consolidated financial statements are the 
responsibility of the Company's management. Our responsibility is to express 
an opinion on these financial statements based on our audits. 

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion. 

In our opinion, such consolidated financial statements present fairly, in all 
material respects, the financial position of Nichols Institute and its 
subsidiaries as of December 31, 1992 and 1993, and the results of their 
operations and their cash flows for each of the three years in the period 
ended December 31, 1993, in conformity with generally accepted accounting 
principles. 

As discussed in Note 11 to the consolidated financial statements, the Company 
has received a subpoena from the Office of the Inspector General of the 
Department of Health and Human Services (OIG) requesting documents in 
connection with an investigation and internal review concerning the possible 
submission of false or improper claims to the Medicare and Medicaid programs. 
No claim or charges have been made against the Company relating to this 
investigation. The ultimate outcome of this investigation cannot presently be 
determined. Accordingly, no provision for any loss that may result from this 
investigation has been made in the accompanying consolidated financial 
statements. 

As discussed in Notes 1 and 3 to the consolidated financial statements, at 
December 31, 1993, the Company was not in compliance with certain covenants 
of its senior note agreements and the senior lenders have not waived those 
covenants. The senior note agreements provide that, as a result of failure to 
comply with the covenants, the note holders have the right to declare the 
entire unpaid balance immediately due and payable, and if that were to occur, 
the Company would not have the funds required to retire the debt unless 
alternative financing is obtained. Management's plans in regard to these 
matters are described in Notes 1 and 3. The note holders' right to declare 
the entire unpaid balance under the note agreements immediately due and 
payable raises substantial doubt about the Company's ability to continue as a 
going concern. The accompanying consolidated financial statements have been 
prepared assuming that the Company will continue as a going concern. The 
financial statements do not include any adjustments that might result from 
the outcome of this uncertainty, except for the classification of amounts due 
under the senior note agreements as current.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
             FOR THE YEARS ENDED DECEMBER 31, 1991, 1992 AND 1993 
                AND FOR THE THREE MONTHS ENDED MARCH 31, 1994 

       (NOTES FOR THE THREE MONTHS ENDED MARCH 31, 1994 ARE UNAUDITED) 
                      NICHOLS INSTITUTE AND SUBSIDIARIES 
     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)1. SUMMARY OF 
                       SIGNIFICANT ACCOUNTING POLICIES 

General--Nichols Institute (the Company) provides esoteric medical diagnostic 
testing to clients nationwide, operates regional clinical laboratories, 
provides substance abuse testing to medical and commercial customers 
nationwide, and manufactures medical diagnostic kits which are distributed 
worldwide. The Company grants credit to customers who consist primarily of 
patients, hospitals, medical centers, clinics, physicians and other clinical 
laboratories. Reimbursement for certain of the Company's services are made 
through the Medicare and Medicaid programs. 

Unaudited Financial Information--In the opinion of management of the Company, 
the unaudited financial statements as of March 31, 1994, and for the three 
months ended March 31, 1993 and 1994, reflect all adjustments which are 
necessary for a fair presentation. During the three months ended March 31, 
1994, the Company incurred unusual charges of $1,789,000 which consisted of 
$1,255,000 in costs related to the "OIG Investigation" and $534,000 in 
financing fees. The results of operations for the three months ended March 
31, 1994 are not necessarily indicative of the results to be achieved for the 
full year. 

Principles of Consolidation--The accompanying consolidated financial 
statements include the accounts of the Company and its wholly-owned 
subsidiaries. All significant intercompany accounts and transactions have 
been eliminated. 

Going Concern and Management's Plans--The consolidated financial statements 
have been prepared assuming that the Company will continue as a going 
concern. This basis contemplates the realization of the Company's assets and 
satisfaction of liabilities in the normal course of conducting business. 

As further discussed in Note 3, at December 31, 1993, the Company was not in 
compliance with certain covenants of its senior note agreements and the 
senior lenders have not waived the covenants. The senior note agreements 
provide that, as a result of the failure to comply with the covenants, the 
noteholders have the right to declare the entire unpaid balance immediately 
due and payable. If that were to occur, the Company would not have the funds 
required to retire the debt unless alternative financing is obtained. The 
noteholders' right to declare the entire unpaid balance under the note 
agreements immediately due and payable raises substantial doubt about the 
Company's ability to continue as a going concern. The consolidated financial 
statements do not include any adjustments that might result from the outcome 
of this uncertainty, except for the classification of the amounts due under 
the senior note agreements as current. 

No waivers have been obtained for the violations at December 31, 1993. 
Additionally, results of operations for the three months ended March 31, 1994 
were not sufficient to meet the financial covenants at March 31, 1994. 
Furthermore, during the first quarter of 1994, the Company suspended its 
negotiations with its senior noteholders to obtain waivers of the violations. 
At that time, the Company began focusing on seeking alternative financing 
arrangements. On April 20, 1994, the Company filed a Registration Statement 
for issuance of $100,000,000 of public debt (see Note 14). In May 1994, the 
Company began merger discussions with Corning Incorporated and suspended its 
efforts for public debt financing (see Note 14). 

The senior debt is expected to be prepaid after the merger is consummated. 
However, no assurances can be made that the merger will be successful. Should 
the merger not occur, management would have to seek alternative financing 
arrangements to refinance the amounts outstanding under the senior notes and 
to obtain working capital financing. 

Inventories--Inventories, which consist principally of diagnostic kits, 
instrumentation equipment held for sale, antisera, laboratory supplies and 
packaging materials, are stated at the lower of cost (first-in, first-out) or 
market. 

Property--Property is stated at cost and is depreciated using the 
straight-line method over the estimated useful lives of the related assets 
which range from three to 40 years. Leasehold improvements are amortized 
using the straight-line method over the shorter of the estimated useful lives 
of the assets or the terms of the related leases. 

Goodwill--Goodwill represents the excess of the cost of purchased businesses 
over the fair value of their net assets. Goodwill is amortized using the 
straight-line method, generally over terms not greater than 25 years. The 
Company periodically evaluates the recoverability of goodwill by comparing 
the carrying value of goodwill to estimated cash flows from related 
operations.

NICHOLS INSTITUTE AND SUBSIDIARIES 

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) 

Purchased Technology--Purchased technology represents the value assigned to 
technologies acquired in connection with the acquisition of London 
Diagnostics, Inc. Purchased technology is amortized using the straight-line 
method over 20 years. On at least an annual basis, the Company assesses the 
recoverability of its purchased technology by comparing the carrying value of 
the technology to estimated future margins from sales of the related products 
and estimated cash flows of the subsidiary which utilizes the technology. 

Covenants Not-to-Compete--Initial payments for covenants not-to-compete and 
subsequent scheduled payments in excess of accruals are capitalized and 
amortized using the straight-line method over the remaining terms of the 
agreements (generally five or eight years). Future obligations under 
covenants not-to-compete are accrued during the periods of forbearance (Note 
12). 

Customer Lists--The cost of customer lists is amortized using the 
straight-line method over the estimated period of benefit, generally five to 
seven years. On at least an annual basis, the Company evaluates the 
recoverability of customer lists utilizing lifing studies or by comparing the 
carrying value of the customer list and other intangibles within the 
subsidiary to estimated cash flows from the related subsidiary. 

Postemployment Benefits--During 1994, the Company adopted the standards 
specified in Statement of Financial Accounting Standards No. 112, Employers' 
Accounting for Postemployment Benefits (SFAS No. 112) (Note 11). The adoption 
of SFAS No. 112 did not have a significant effect on the Company's 
consolidated financial statements. 

Long-Term Debt--As a result of the Company's failure to comply with the 
covenants in its senior note agreements at December 31, 1993, the fair value 
of the Company's long-term debt was not readily determinablde (Note 3). 

Revenue Recognition--Revenues are generally recognized when testing services 
are completed or upon shipment of products. Revenues for research and 
development contracts are recognized on a percentage of completion basis 
(Note 9). 

Contractual Allowances--The Company provides services to certain patients 
covered by various third-party payer programs including the Federal Medicare 
and state Medicaid programs. Billings for services under these third-party 
payer programs are included in revenues net of allowances for estimated 
differences between list prices and allowable program rates. Adjustments to 
the allowances based on final settlement with the programs are recorded upon 
settlement. Total contractual allowances offset against revenues during the 
years ended December 31, 1991, 1992 and 1993 were $31,241,000, $42,110,000 
and $43,534,000, respectively. 

Net revenues from direct billings under Medicare and Medicaid programs, net 
of contractual allowances, during the years ended December 31, 1991, 1992 and 
1993 approximated 12%, 13% and 13% of net revenues or $27,273,000, 
$37,345,000 and $37,201,000, respectively. Because the Company does not 
directly bill Medicare and Medicaid for most testing services it provides to 
hospitals and certain clinical laboratories, the percentages of the Company's 
revenues originating from patients who participate in the Medicare and 
Medicaid programs may significantly exceed the amounts indicated above. 

Interest--Interest costs of $570,000 were capitalized during 1991 in 
connection with the Company's facility development (Note 4). 

Research and Development Expenditures--Research and development expenditures 
of the Company are expensed as incurred (Note 9). 

Income Taxes--During 1992, the Company adopted the standards specified in 
Statement of Financial Accounting Standards No. 109, Accounting for Income 
Taxes (SFAS No. 109) (Note 8). 

Net Income (Loss) Per Common and Common Equivalent Share--Net income (loss) 
per common and common equivalent share is based on the weighted average 
number of shares of Class A Common Stock, Class B Common Stock and Class C 
Common Stock (collectively, common shares) and (in 1991 and for the three 
months ended March 31, 1993) common equivalent shares outstanding during the 
period. Common equivalent shares relate to shares issuable upon the 
conversion of Preferred Stock (Note 5), shares issuable upon the exercise of 
stock options and warrants (Note 6), and shares to be issued in the future as 
consideration for covenants not-to-compete (Note 12). 

Reclassifications--Certain amounts as previously reported have been 
reclassified to conform to the current period presentation.

2. BANK FINANCING 

At December 31, 1993, the Company had a $15,000,000 credit agreement with a 
domestic bank, which was to expire on June 1, 1994 and which provided for 
unsecured borrowings with interest at the prime rate plus one-fourth of one 
percent (6-1/4% at December 31, 1993). The agreement required that the 
Company pay commitment fees and meet certain financial covenants. No 
borrowings were outstanding under this agreement as of December 31, 1993. As 
a result of the Company's operating loss incurred in the fourth quarter of 
1993, the Company was in default of certain covenants under the credit 
agreement and the credit agreement has been terminated. 

The Company has historically used this line to alleviate temporary working 
capital shortfalls and believes it is prudent to maintain a working capital 
line. In conjunction with the proposed $100,000,000 public debt offering, the 
Company had obtained commitments for lines of credit providing for borrowings 
of up to $25,000,000. These commitments expired as a result of the suspension 
of the public debt offering (Note 1). Should the merger with Corning 
Incorporated not occur (Note 14), the Company will have to seek new short 
term financing arrangements. 

The Company also had a revolving credit agreement with a German bank which 
provided for borrowings of up to DM 1,500,000 (approximately $864,000 at the 
exchange rate in effect as of December 31, 1993). As of December 31, 1993, 
the agreement had expired and has not been renewed.

The Company's results of operations in the fourth quarter of 1993, before 
restructuring and unusual charges of $16,000,000 (Note 10), were not 
sufficient to meet the financial covenants under the Company's senior note 
agreements at December 31, 1993. The senior note agreements provide that, as 
a result of the failure to comply with the covenants, the noteholders have 
the right to declare the entire unpaid balance immediately due and payable, 
and as such, the remaining obligations of $62,176,000 under the note 
agreements were classified as current as of December 31, 1993. The covenants 
were not met again at March 31, 1994. As such, the obligations under the 
senior note agreements as of December 31, 1993 and March 31, 1994 are 
classified as current (Note 1).

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) 

The senior notes require semi-annual interest payments, contain provisions 
for prepayment penalties, preclude mergers under certain circumstances and 
place limits on investments, capital expenditures, acquisition payments, new 
debt issuances and leasing commitments, and, upon default, prohibit cash 
dividends. 

The 9.5% and certain other notes were issued in connection with business 
acquisitions (Note 12) and are subordinated to bank financing and senior 
notes. Other notes aggregating $543,000 at December 31, 1993 are convertible 
at the option of the noteholders into common stock of a wholly-owned 
subsidiary of the Company in the event of an underwritten public offering of 
that subsidiary's common stock. The number of shares issuable upon such 
conversion would be equal to the unpaid principal balance of the notes plus 
any accrued but unpaid interest divided by the offering price of the stock. 
The notes may also be exchanged, at the option of the holders, for Class A 
Common Stock of the Company based on the market value of the Company's Class 
A Common Stock for the first 20 trading days of the 30 trading days prior to 
the date of exchange. During 1993, $154,000 of the notes' principal and 
accrued interest balances were exchanged for the Company's Class A Common 
Stock. 

Principal maturities of long-term debt (excluding obligations under capital 
leases), assuming amounts due under the senior note agreements are classified 
as current, during each of the five years in the period ending December 31, 
1998 and thereafter are $64,988,000, $2,574,000, $1,636,000, $1,070,000, 
$166,000 and $145,000, respectively. 

4. LEASING ARRANGEMENTS 
The Company conducts certain of its operations from leased facilities and 
also leases certain equipment. 

The Company leases its primary facility under a capital lease which includes 
a lease of a portion of the Company's land to the lessor and a leaseback of 
the land and building by the Company. The lease expires in March 2031. The 
amount of rent payable by the Company under the lease is approximately 
$3,840,000 per year. Rent under the land and building lease is subject to 
escalation every five years based on changes in a designated consumer price 
index. The Company has options to buy its primary facility and terminate the 
facilities lease at various times during the lease term at a formula price 
which varies over time. 

Property included in the accompanying consolidated balance sheets under 
capital leases is as follows:

NICHOLS INSTITUTE AND SUBSIDIARIES 

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) 

The Company is committed under noncancelable operating leases to make minimum 
annual payments during the five years in the period ending December 31, 1998 
and thereafter of $6,171,000, $4,751,000, $3,603,000, $2,960,000, $2,445,000 
and $924,000, respectively. 

5. STOCKHOLDERS' EQUITY 
The Company's Preferred Stock is issuable in series, having such rights, 
preferences and privileges as are determined by the Board of Directors when 
each series is designated. The Company has the right to redeem the Series E 
Convertible Preferred Stock at any time for cash equal to $350 per share plus 
the amount of accrued and unpaid dividends. Each share of Series E 
Convertible Preferred Stock converts automatically into five shares of the 
Company's Class A Common Stock and five shares of its Class C Common Stock at 
any time if the market price per share of Company Class A Common Stock equals 
or exceeds $35 per share for ten out of 20 consecutive trading days through 
January 4, 1995. Any Series E Convertible Preferred Stock which remain 
outstanding as of January 4, 1995 will automatically convert at a conversion 
price equal to $350, divided by twice the market price of the Company's Class 
A Common Stock for the 20-day trading period ending on January 4, 1995. Upon 
such conversion, the holder will also receive a corresponding number of 
shares of Class C Common Stock. 

Although the terms of the Series E Convertible Preferred Stock provide for 
dividends to accrue only during the third and fourth years after issuance, 
for financial reporting purposes, such dividends are treated as if accrual 
began on the date of the related stock issuance and continue through the 
conversion dates, at which time the accrued dividends are credited to 
additional paid-in capital. As of December 31, 1993, accrued dividends on the 
Series E Convertible Preferred Stock aggregated $340,000. Approximately 
$193,000 in cash dividends on the Series E Convertible Preferred Stock were 
paid during 1993. Due to the Company's failure to meet certain financial 
covenants of its senior note agreements at December 31, 1993 (Note 3), the 
Company was precluded from paying cash dividends and $96,000 of dividends 
were in arrears at December 31, 1993. Additionally, dividends of $96,000 
which were due in January 1994 have not been paid. 

As of March 31, 1994, accrued dividends on the Series E Convertible Preferred 
Stock aggregated $399,000 and the Company continues to be precluded from 
paying cash dividends. At March 31, 1994, $192,000 of dividends were in 
arrears. 

Except for the election and removal of directors, other matters for which a 
class vote is required by law, and certain related party business 
combinations, holders of Class A Common Stock and Class B Common Stock vote 
as a single class. Holders of Class A Common Stock are entitled to one-tenth 
of a vote for each share held. Holders of Class B Common Stock are entitled 
to one full vote for each share held. The Company's Class C Common Stock is a 
nonvoting class of common stock. With respect to the election of directors, 
the holders of Class A Common Stock elect two directors (representing 25% of 
the number of directors to be elected), and the holders of Class B Common 
Stock elect six directors (representing 75% of the number of directors). At 
the discretion of the holders of Class B Common Stock, Class B Common Stock 
is convertible on a share-for-share basis into Class A Common Stock. 

On May 22, 1991, the Company declared a one-for-two reverse split of the 
Company's Class A Common Stock and Class B Common Stock. Also on May 22, 
1991, the Board of Directors declared a stock dividend of one share of Class 
C Common Stock for each outstanding share of Class A and Class B Common Stock 
after giving effect to the reverse stock split. The dividend was paid on, and 
to stockholders of record as of, June 4, 1991. 

At December 31, 1993, 3,815,543 and 3,997,424 shares of Company Class A 
Common Stock and Class C Common Stock, respectively, had been reserved for 
future issuance in connection with business acquisitions, in the event of 
future debt exchanges, for conversion of Series E Convertible Preferred Stock 
and option exercises. 

6. STOCK OPTIONS AND WARRANTS 
The Company has stock option plans which provide options to purchase a 
maximum of 81,760 and 2,759,553 shares of the Company's Class A Common Stock 
and Class C Common Stock, respectively. The options may be granted at prices 
not less than the fair value at the date of grant. Options granted generally 
become exercisable in three equal annual installments during the three-year 
period after the date of grant. Options granted from August 1989 to February 
1991 generally expire five years from the date of grant, and options granted 
after February 1991 generally expire ten years from the date of grant.

Management believes it is more likely than not that the Company will fully 
utilize its deferred tax assets by applying them against taxable income to be 
generated in future years. The Company estimates that the majority of its 
deferred tax assets will be realized during the next three years. 

A reconciliation between the provision (benefit) for income taxes computed by 
applying the Federal statutory tax rate to income (loss) before taxes and the 
actual provision (benefit) for income taxes is as follows for the years ended

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) 

At December 31, 1993, the Company had $3,006,000 in net operating loss 
carryforwards available to offset future taxable income arising from business 
acquisitions. Net operating losses are subject to annual limitations and 
expire between 2002 and 2006. 

The Internal Revenue Service (IRS) is examining the Company's 1988 through 
1992 tax returns. The IRS has challenged certain deductions of the Company 
and covenants not-to-compete entered into in connection with certain 
acquisitions. During 1993, the Company filed a protest with the IRS against 
the disallowance of these tax deductions and has requested a conference with 
the IRS Appellate Conference on the matter. In April 1994, Nichols received a 
proposed settlement from the IRS regarding the deduction of customer lists 
acquired in connection with its Dallas operations. Nichols is currently 
evaluating the settlement offer. 

Although the amounts involved would be material if the deductions are 
ultimately disallowed, the Company believes that the deductions are valid 
because the noncompete agreements meet all of the judicially established 
tests for such agreements and that this matter will not have a material 
adverse effect on its consolidated financial condition or its results of 
operations. Accordingly, no provision for losses relating to this matter has 
been recorded in the accompanying consolidated financial statements. 

9. RESEARCH AND DEVELOPMENT ARRANGEMENTS 
The Company has various agreements with unrelated limited partnerships, which 
provide for research and development of certain medical diagnostic kits. The 
Company purchased the technology resulting from the research and pays 
royalties based on a percentage of revenues from the sale of certain 
diagnostic kits ($1,389,000, $1,002,000 and $934,000 for the years ended 
December 31, 1991, 1992 and 1993, respectively). All development under these 
contracts was complete as of December 31, 1987. 

In connection with its acquisition of London Diagnostics, Inc. (Note 12), the 
Company became a party to an arrangement with an independent distributor 
(under which the distributor provided a portion of the funding) to develop 
and provide certain medical diagnostic kits utilizing chemiluminescent 
technology. Revenues from the arrangement were recognized on the percentage 
of completion basis. During the years ended December 31, 1992 and 1993, 
revenues of approximately $1,113,000 and $744,000, respectively, were 
recognized from such arrangement. Research and development costs expended 
under the arrangement amounted to $2,017,000 and $340,000 during the years 
ended December 31, 1992 and 1993, respectively. Development under the 
arrangement was completed during 1993. Under this arrangement, the Company 
owns all the rights to the diagnostic kits developed, and the distributor has 
the right to purchase the kits from the Company, manufacture the kits in 
conjunction with the Company, and market in the Far East any such kits 
purchased, manufactured or developed. Under a separate licensing agreement, 
the distributor was granted rights to the remaining technology which enabled 
it to manufacture the kits on a stand-alone basis. During the years ended 
December 31, 1992 and 1993, the Company received $625,000 and $1,000,000, 
respectively, relating to the separate licensing agreement. All amounts due 
from the distributor under this agreement had been received as of December 
31, 1993. 

Company-sponsored research and development expenses amounted to $2,970,000, 
$2,962,000 and $3,905,000 during the years ended December 31, 1991, 1992 and 
1993, respectively. 

10. RESTRUCTURING AND UNUSUAL CHARGES 
During 1990, the Company formed a joint venture, Nichols Institute 
Laboratories North Texas, Ltd., with the owners of three hospital systems 
located in the Dallas-Fort Worth area to establish and operate a 
newly-developed shared clinical laboratory to serve those hospital systems, 
as well as other healthcare providers in the area. The joint venture (the 
Venture) was a limited partnership with a wholly-owned subsidiary of the 
Company acting as the general partner. The partnership agreement provided 
that the general partner absorbs 100% of cumulative losses in excess of 
partner contributions, which were exhausted during 1991. 

During the year ended December 31, 1991, the Company's share in losses of the 
Venture was $5,098,000 due to substantial operating losses incurred by the 
Venture and the Company's share ($2,917,000) of restructuring charges 
recorded by the Venture related to the write-down of certain customer lists 
and fixed assets, as well as a direct restructuring charge ($875,000) 
recorded directly by the Company primarily to provide for severance pay of 
its Dallas operations.

NICHOLS INSTITUTE AND SUBSIDIARIES 

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) 

In April 1992, the Company acquired the limited partners' interests in the 
Venture in exchange for 225,000 shares of the Company's Class C Common Stock, 
valued at $2,137,500, as part of a plan adopted during the latter part of 
1991 which enabled the Company to obtain the control of the Venture necessary 
for it to take actions to reduce the continuing significant operating losses 
of the Dallas laboratory. The purchase price was allocated to goodwill. 

In 1992, the Company decided that operating losses of the Dallas operations 
could only be reduced by significantly downsizing the Dallas operation. 
Accordingly, the Company recorded a restructuring charge of $13,000,000 as of 
June 30, 1992 to provide for the estimated costs of effecting the downsizing. 
The Company continued to refine the components of the restructuring charge 
until December 31, 1992, at which time the restructuring charge was comprised 
of a provision for write-downs of assets that were expected to be impaired as 
a result of the downsizing of the Dallas operations ($1,500,000), a partial 
write-down of customer lists ($2,400,000) and write-down of goodwill 
established upon the purchase of the limited partners' interest in the 
Venture ($2,700,000), provisions for future losses at the Dallas location 
through the estimated date of completion of the downsizing ($4,400,000), 
severance pay and related costs ($500,000), costs associated with subleasing 
the Dallas facility ($700,000), professional fees ($500,000) and other 
related costs ($300,000). The downsizing of the Dallas operations 
contemplated by the 1992 restructuring was largely complete as of September 
30, 1993. The amounts ultimately incurred related to the 1992 restructuring 
charge were not significantly different from those contemplated by the 
Company. 

The provision for lease termination recorded in connection with the 1992 
restructuring was based on the expectations that the Company would sublet the 
entire Dallas facility to an interested third party. However, these 
negotiations were terminated during 1993. Subsequently, the Company decided 
it was not practicable to continue pursuing the sublease opportunities and 
entered negotiations to terminate the lease. Termination costs of the lease, 
in excess of those contemplated during the 1992 restructuring, are included 
in the restructuring charge recorded by the Company in 1993 as described 
below. 

During 1993, the Company focused efforts to consolidate, standardize and 
integrate its various acquired laboratories and in November 1993 adopted a 
plan to consolidate its Texas, Bay Area (Oakland) and Upper Midwest Regional 
Laboratory operations, and to implement a further automation of its Reference 
Laboratories' operations. This plan resulted in the Company establishing a 
$12,840,000 restructuring reserve in the fourth quarter of 1993. The charge 
included write-offs of customer lists impaired as a result of the 
restructuring ($1,900,000) and property and other assets ($1,500,000) 
impaired as a result of the downsizing of certain of the locations, as well 
as provisions for severance pay, outplacement fees and related costs 
($4,400,000), costs of terminating excess facility and equipment leases 
($3,000,000, which included $1,800,000 paid as settlement for terminating the 
Dallas facility lease on January 31, 1994), strategic and financial 
consulting services ($900,000) incurred as of December 31, 1993, professional 
fees ($300,000) and certain other costs associated with the restructuring of 
the Company's operations ($840,000). Implementation of the restructuring 
plan, which is expected to be substantially complete by the end of 1994, will 
require significant cash expenditures. The Company estimates that total cash 
expenditures to effect the restructuring plan will approximate $9,600,000, of 
which approximately $1,800,000 was expended in 1993 and approximately 
$7,000,000 is expected to be expended during 1994, with the remainder 
expected to be expended thereafter. The Company expects that the cash 
requirements to effect the restructuring will be satisfied through cash 
generated from operations. 

During the three months ended March 31, 1994, approximately $2,300,000 was 
expended. As of March 31, 1994, the 1993 restructuring programs are largely 
progressing as was contemplated when the restructuring charge was recorded in 
the fourth quarter of 1993. 

Additionally, the Company incurred unusual charges of $3,160,000 during the 
year ended December 31, 1993. The charges primarily consisted of the 
write-off of impaired assets, including customer lists acquired in connection 
with business acquisitions in prior years ($1,600,000) and certain fixed 
assets whose values have been impaired primarily as a result of the Company's 
commitment to further automate the computerization of its financial 
information and laboratory systems ($600,000). The unusual charges also 
included costs associated with responding to a subpoena received during the 
year (Note 11). 

11. COMMITMENTS AND CONTINGENCIES 
On August 30, 1993, the Company received a subpoena from the Office of the 
Inspector General of the Department of Health and Human Services (OIG) 
requesting documents in connection with an investigation and inter
<PAGE>

NICHOLS INSTITUTE AND SUBSIDIARIES 

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) 

nal review concerning the possible submission of false or improper claims to 
the Medicare and Medicaid programs. The Company believes other independent 
clinical laboratories have received similar notices and believes these are a 
part of a nationwide audit and investigation of certain clinical laboratory 
industry practices. The Company has not been charged with any violation and 
intends to cooperate fully in the government's investigation. At this time, 
it is too early to predict the results of the investigation or its impact, if 
any, on the Company's consolidated financial condition or results of 
operations. Accordingly, no provision for any loss, if any, that may result 
upon the resolution of this investigation has been made in the accompanying 
consolidated financial statements. 

The Company is obligated under various Academic Associate agreements which 
relate to the research and development and marketing of assays and reagents. 
Generally, the agreements are cancelable upon two to six months' notice after 
their initial term (usually two to five years) and provide for equal periodic 
payments or periodic payments based on a percentage of revenue derived from 
sales of the related assays and reagents. 

In connection with certain business acquisitions (Note 12), the Company 
entered into covenants not-to-compete with the acquired companies' former 
stockholders. In addition to payments already made in accordance with the 
agreements, the covenants require future cash payments during the five years 
ending December 31, 1998 and thereafter of $4,188,000, $4,166,000, 
$3,344,000, $783,000, $787,000 and $541,000, respectively, and the future 
issuance of 6,780 shares each of Company Class A and Class C Common Stock. 
The covenants also require the issuance of 197,678 shares of Company Common 
Stock, of which 160,781 shares have been issued as of December 31, 1993. The 
shares issued in conjunction with the covenants not to compete were valued at 
their estimated fair market value at the date of consummation of the merger 
($12.50 per share). As of December 31, 1993, $5,175,000 had been accrued 
under the agreements, of which $1,981,000 is included in other noncurrent 
liabilities in the accompanying consolidated balance sheets. The obligation 
to pay amounts due under the covenants not-to-compete entered into in 
connection with the acquisition of Clinical Laboratories of Lincoln, Inc. 
(CLL) in 1988 is collateralized by a pledge of the stock of CLL. The terms of 
the pledge agreement require the Company to maintain the separate existence 
and operations of CLL, impose certain financial covenants with respect to CLL 
and restrict the extent to which the operations of CLL can be integrated with 
those of the Company. The terms are effective until 1996, when the amounts 
due under the covenants not-to-compete are required to have been paid in 
full. 

The Company is a party to various litigation matters which are incidental to 
its business. Although the results of the litigation cannot be predicted with 
certainty, management believes that the final outcome of such matters will 
not have a material adverse effect on the Company's consolidated financial 
statements. 

Certain key employees participate in a severance package that provides 
compensation for a specified period of time in the event the employee is 
terminated as a result of a change in control of the Company or a merger. 
Certain key executives have agreements with the Company that provide for 
compensation for a specified period of time subsequent to their termination 
of employment for reasons defined in the agreements. The Company provides for 
the accrual of such benefits when the rights vest and payment is probable and 
reasonably estimatable. 

12. BUSINESS ACQUISITIONS 
As described in Note 10, during 1990 the Company formed a joint venture, 
Nichols Institute Laboratories North Texas, Ltd. (the Venture). In April 
1992, the Company purchased the limited partners' interests in the Venture in 
exchange for 225,000 shares of Company Class C Common Stock valued at 
$2,137,500. The purchase price was allocated to goodwill. Commencing on the 
date of acquisition, the Venture was consolidated in the Company's financial 
statements. 

In January 1991, the Company acquired all of the outstanding stock of MAWD 
Medical Laboratories, Inc. (MAWD). Initial consideration paid by the Company 
for the business and related covenants not-to-compete consisted of $1,740,000 
in cash, future payments having a then present value of $2,000,000, and 
11,128 shares of Series E Convertible Preferred Stock (Note 5). In connection 
with the acquisition, contingent payments consisting of 3,570 additional 
shares of Series E Convertible Preferred Stock were issued and cash payments 
of $1,250,000 were made during 1993. The obligation for these contingent 
payments was recorded during 1992, when it became probable that the payments 
would be made. The acquisition of MAWD was accounted for as a purchase with 
the excess of the purchase price of $1,560,000 over the fair market value of 
tangible assets (which approximated the carrying value of such assets) being 
allocated to goodwill.
<PAGE>

NICHOLS INSTITUTE AND SUBSIDIARIES 

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) 

During 1991, the Company acquired PathLab, Inc. (PathLab) by merger. 
Consideration paid by the Company consisted of approximately $6,728,000 in 
cash and $2,616,000 of five-year subordinated promissory notes bearing 
interest at 9.5% per annum (Note 3). Additionally, PathLab entered into 
noncompetition agreements with two of its former stockholders. The agreements 
have a term of eight years and provide for future payments having an initial 
present value of $1,850,000. The acquisition of PathLab was accounted for as 
a purchase with the excess of the purchase price of $10,620,000 over the fair 
market value of tangible assets (which approximated the carrying value of 
such assets) being allocated to goodwill. 

During 1991, the Company acquired MPC Laboratory (MPC) by merger. 
Consideration paid to MPC shareholders in connection with the acquisition 
approximated $7,000,000, of which approximately $1,075,000 represented 
covenant not-to-compete arrangements with certain MPC shareholders. The 
acquisition of MPC was accounted for as a purchase with the excess of the 
purchase price of $4,850,000 over the fair market value of tangible assets 
(which approximated the carrying value of such assets) being allocated to 
goodwill. 

During April 1992, the Company acquired London Diagnostics, Inc. (London), 
which had primarily been engaged in the development, manufacture and 
distribution of medical diagnostic test kits using direct label 
chemiluminescent technology. Consideration paid to London's shareholders was 
1,315,050 shares of the Company's Class C Common Stock valued at $12,641,000 
which, together with the other costs of the acquisition, was allocated to 
purchased technology. The value of the Class C Common Stock was based upon 
the average trading prices of the Company's Class C Common Stock for a 
ten-day period preceding the acquisition consummation date. The value during 
the ten-day period was utilized because the sellers were guaranteed a fixed 
purchase price based upon pre-closing stock trading prices. 

The unaudited consolidated pro forma results of operations for the year ended 
December 31, 1991, as if the Venture, PathLab, MPC and London acquisitions 
had occurred at the beginning of that year, are as follows:

Gross profit represents net revenues less cost of sales. See Note 10 for 
discussion of restructuring charges recorded during the second quarter of 
1992 and the fourth quarter of 1993. 

Although the Company realized benefits from cost reduction measures 
implemented during the fourth quarter of 1992, including salary reductions 
and freezes, and the suspension of vacation accruals and 401(k) matching 
contributions, these benefits were largely offset by nonrecurring charges 
associated with a reorganization of the Company's management structure. 

During the fourth quarter of 1993, the Company recorded an inventory 
adjustment of approximately $400,000 and reclassified certain costs of 
approximately $600,000 from selling, general and administrative expenses to 
cost of sales. 

14. SUBSEQUENT EVENTS 
On April 20, 1994, the Company filed a Form S-1 Registration Statement with 
the Securities and Exchange Commission (SEC) relating to a proposed $100 
million public debt offering (the Offering). On June 1, 1994, the Board of 
Directors approved a plan of merger with Corning Incorporated. At that same 
time, the Company suspended its efforts to seek public debt financing. Under 
the terms of the merger agreement, all of the Company's common shares will be 
exchanged for $13.00 of Corning Incorporated's common stock (subject to 
certain limitations). Pursuant to its terms, the Company's Series E 
Convertible Preferred Stock will be converted into Corning Incorporated's 
common stock at the time of the merger. The merger is contingent upon, among 
other things, treatment of the merger as a pooling for accounting purposes. 
No assurances can be given that the merger will be completed. Should the 
merger be completed this would be considered a qualifying event under certain 
of the key executive severance agreements (Note 11).

AGREEMENT AND PLAN OF MERGER, dated as of June 1, 1994, as amended, among 
CORNING INCORPORATED, a New York corporation ("Parent"), APPLE ACQUISITION 
CORP., a Delaware corporation ("Sub") and a direct wholly owned subsidiary of 
Parent, and NICHOLS INSTITUTE, a Delaware corporation (the "Company"). 

WHEREAS, the respective Boards of Directors of Parent, Sub and the Company 
have approved the merger of Sub with and into the Company (the "Merger"), 
upon the terms and subject to the conditions set forth in this Agreement and 
in accordance with the General Corporation Law of the State of Delaware (the 
"DGCL"), whereby each issued and outstanding share of Company Common Stock 
(as defined in Section 3.01(c)) (including shares of Company Common Stock 
issuable upon the automatic conversion of Company Preferred Stock (as defined 
in Section 3.01(c)) in accordance with the terms thereof as of the Effective 
Time) other than shares to be cancelled in accordance with Section 2.01(b), 
will be converted into the right to receive shares of common stock, par value 
$.50 per share, of Parent ("Parent Common Stock"); 

WHEREAS, the Merger requires the approval of the holders of a majority of the 
votes which the outstanding shares of the Company Common Stock are entitled 
to cast on such matter voting as a single class (the "Company Stockholder 
Approval"); 

WHEREAS, concurrently with the execution of this Agreement and as an 
inducement to Parent to enter into this Agreement, Dr. Albert L. Nichols, a 
stockholder of the Company (the "Significant Stockholder"), has entered into 
an agreement with Parent (the "Significant Stockholder Agreement") pursuant 
to which the Significant Stockholder has, among other things, agreed to vote 
his shares of Company Common Stock in favor of the Merger; 

WHEREAS, Parent, Sub and the Company desire to make certain representations, 
warranties, covenants and agreements in connection with the Merger and also 
to prescribe various conditions to the Merger; 

WHEREAS, for Federal income tax purposes, it is intended that the Merger 
shall qualify as a reorganization within the meaning of Sections 368(a)(1)(A) 
and (a)(2)(E) of the Internal Revenue Code of 1986, as amended (the "Code"); 
and 

WHEREAS, for accounting purposes, it is intended that the Merger shall be 
accounted for as a "pooling-of-interests"; 

NOW, THEREFORE, in consideration of the representations, warranties, 
covenants and agreements contained in this Agreement, the parties agree as 
follows: 

                                  ARTICLE I

SECTION 1.01. The Merger.  Upon the terms and subject to the conditions set 
forth in this Agreement, and in accordance with the DGCL, Sub shall be merged 
with and into the Company at the Effective Time (as hereinafter defined). 
Following the Merger, the separate corporate existence of Sub shall cease and 
the Company shall continue as the surviving corporation (the "Surviving 
Corporation") and shall succeed to and assume all the rights and obligations 
of the Company and of Sub in accordance with the DGCL. 

SECTION 1.02. Closing. The closing of the Merger will take place at 10:00 
a.m. on a date to be specified by the parties, which shall be no later than 
the second business day after satisfaction or waiver of the conditions set 
forth in Article VI (the "Closing Date"), at the offices of Wachtell, Lipton, 
Rosen & Katz, 51 West 52nd Street, New York, NY 10019 unless another time, 
date or place is agreed to in writing by the parties hereto. 

SECTION 1.03. Effective Time. Subject to the provisions of this Agreement, as 
soon as practicable on or after the Closing Date, the parties shall file a 
certificate of merger or other appropriate documents (in any such case, the 
"Certificate of Merger") executed in accordance with the relevant provisions 
of the DGCL and shall make all other filings or recordings required under the 
DGCL. The Merger shall become effective at such time as the Certificate of 
Merger is duly filed with the Delaware Secretary of State, or at such other 
time as Sub and the Company shall agree should be specified in the 
Certificate of Merger (the date and time of such filing, or such later date 
or time as may be set forth therein, being the "Effective Time"). 

SECTION 1.04. Effects of the Merger. The Merger shall have the effects set 
forth in Section 259 of the DGCL. 

SECTION 1.05. Certificate of Incorporation and By-laws. (a) The certificate 
of incorporation of Sub as in effect immediately prior to the Effective Time 
shall be the certificate of incorporation of the Surviving Corporation 
(except that such certificate of incorporation shall be amended at the 
Effective Time to provide that the name of the Surviving Corporation shall be 
"Nichols Institute") until thereafter changed or amended as provided therein 
or by applicable law.

(b) The by-laws of Sub as in effect at the Effective Time shall be the 
by-laws of the Surviving Corporation, until thereafter changed or amended as 
provided therein or by applicable law. 

SECTION 1.06. Directors. The directors of Sub at the Effective Time shall 
continue as the directors of the Surviving Corporation, until the earlier of 
their resignation or removal or until their respective successors are duly 
elected and qualified, as the case may be. 

SECTION 1.07. Officers. The officers of the Company immediately prior to the 
Effective Time shall become the officers of the Surviving Corporation, until

               EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE 
              CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES 

SECTION 2.01. Effect on Capital Stock. At the Effective Time, by virtue of 
the Merger and without any action on the part of Parent, Sub, the Company, or 
the holders of any shares of Company Common Stock or any shares of capital 
stock of Sub: 

  (a) Capital Stock of Sub. Each share of the capital stock of Sub issued and 
outstanding immediately prior to the Effective Time shall be converted into 
and exchanged for one fully paid and nonassessable share of common stock of 
the Surviving Corporation. 

  (b) Cancellation of Treasury Stock and Parent Owned Stock. Each share of 
Company Common Stock that is owned by the Company or by any subsidiary of the 
Company and each share of Company Common Stock that is owned by Parent, Sub 
or any other subsidiary of Parent immediately prior to the Effective Time 
shall automatically be cancelled and retired without any conversion thereof 
and no consideration shall be delivered with respect thereto. 

  (c) Conversion of Common Stock. Each share of Company Common Stock issued 
and outstanding as of the Effective Time other than shares to be cancelled in 
accordance with Section 2.01(b) and other than shares of Class B Stock which 
are Objecting Shares (as defined in clause (d) below) shall be converted, 
subject to Section 2.02(e), into the right to receive that number (the 
"Exchange Ratio") of shares of Parent Common Stock, rounded to the nearest 
thousandth, or if there shall not be a nearest thousandth, to the next lower 
thousandth, equal to the quotient derived by dividing $13.00 by the average 
of the per share closing prices on the New York Stock Exchange, Inc. (the 
"NYSE") of Parent Common Stock (as reported in the NYSE Composite 
Transactions) during the 10 consecutive trading days ending on the fifth 
trading day prior to the Company Stockholders' Meeting (as defined in Section 
5.01(b)); provided, however, that in no event will the Exchange Ratio be 
greater than 0.491 and if the Exchange Ratio, as calculated, would be above 
that limit, then it shall be fixed at such maximum limit; provided, further, 
that in the event the Exchange Ratio, as calculated (without reference to the 
foregoing proviso), would equal or be greater than 0.638, then the Company 
may terminate this Agreement. If, prior to the Effective Time, Parent should 
split or combine the Parent Common Stock, or pay a stock dividend or other 
stock distribution in Parent Common Stock, then the Exchange Ratio (including 
the maximum limit thereof) will be appropriately adjusted to reflect such 
split, combination, dividend or other distribution. Each share of the Company 
Preferred Stock issued and outstanding as of the Effective Time (other than 
shares of Company Preferred Stock which are Objecting Shares) shall be 
converted, subject to Section 2.02(e), into the right to receive Parent 
Common Stock in the manner and amount provided for pursuant to the terms of 
the Company Preferred Stock. Each share of Parent Common Stock issued 
pursuant to this Section 2.01(c) shall be accompanied by one Right (as 
defined in Section 3.02(b)) unless the Rights shall not be outstanding as of 
the Effective Time. 

  As of the Effective Time, all such shares of Company Common Stock and 
Company Preferred Stock shall no longer be outstanding and shall 
automatically be cancelled and retired and shall cease to exist, and each 
certificate previously representing any such shares (including any 
certificate theretofore representing Company Preferred Stock) shall 
thereafter represent the right to receive a certificate representing the 
shares of Parent Common Stock into which such Company Common Stock was 
converted in the Merger. The holders of such certificates previously 
evidencing such shares of Company Common Stock and Company Preferred Stock 
outstanding immediately prior to the Effective Time shall cease to have any 
rights with respect to such shares of Company Common Stock or Company 
Preferred Stock as of the Effective Time except as otherwise provided herein 
or by law. Such certificates previously representing shares of Company Common 
Stock and Company Preferred Stock shall be exchanged for certificates 
representing whole shares of Parent Common Stock issued
<PAGE>
<PAGE>
 
in consideration therefor upon the surrender of such certificates in 
accordance with the provisions of Section 2.02, without interest. No 
fractional share of Parent Common Stock shall be issued, and, in lieu 
thereof, a cash payment shall be made pursuant to Section 2.02(e). 

  (d) Notwithstanding anything in this Agreement to the contrary, each share 
of Class B Stock and each share of Company Preferred Stock which is issued 
and outstanding immediately prior to the Effective Time and which is held by 
a stockholder who has not voted such shares in favor of adoption of the 
Merger Agreement or consented thereto in writing (in the case of shares of 
Class B Stock) and who has demanded appraisal rights with respect thereto in 
the manner provided in Section 262 of the DGCL (collectively, the "Objecting 
Shares") shall not be converted into or represent the right to receive the 
merger consideration provided for in paragraph (c) above but, instead, the 
holders thereof shall be entitled to receive payment of the appraised value 
of such shares in accordance with the provisions in Section 262 of the DGCL; 
provided, however, that if any holder of Objecting Shares shall subsequently 
withdraw such demand for appraisal of such shares, or lose the right to 
appraisal as provided in Section 262 of the DGCL, such holder or holders (as 
the case may be) shall forfeit the right to appraisal of such shares and such 
shares shall thereupon be deemed to have been automatically converted into 
the right to receive, as of the Effective Time, the merger consideration 
provided for in paragraph (c) above, without any interest thereon. 

SECTION 2.02. Exchange of Certificates. (a) Exchange Agent. Prior to the 
Effective Time, Parent shall enter into an agreement with such bank or trust 
company as may be designated by Parent and as shall be reasonably 
satisfactory to the Company (the "Exchange Agent"), and as contemplated by 
such agreement, Parent shall deposit, or shall cause to be deposited, with 
the Exchange Agent as of the Effective Time (or otherwise when requested by 
the Exchange Agent from time to time in order to effect any exchange pursuant 
to this Section 2.02), for the benefit of the holders of shares of Company 
Common Stock, for exchange in accordance with this Article II through the 
Exchange Agent, certificates representing the shares of Parent Common Stock 
issuable pursuant to Section 2.01 in exchange for outstanding shares of 
Company Common Stock (such certificates representing shares of Parent Common 
Stock, together with any dividends or distributions with respect thereto, 
being collectively referred to as the "Exchange Fund"). The Exchange Agent 
shall, pursuant to irrevocable instructions, deliver the Parent Common Stock 
contemplated to be issued pursuant to Section 2.01 out of the Exchange Fund. 
Except as contemplated by Section 2.02(e), the Exchange Fund shall not be 
used for any other purpose. 

(b) Exchange Procedure. As soon as reasonably practicable after the Effective 
Time, Parent shall instruct the Exchange Agent to mail to each holder of 
record of a certificate or certificates which immediately prior to the 
Effective Time represented outstanding shares of Company Common Stock or 
Company Preferred Stock (the "Certificates"), (i) a letter of transmittal 
(which shall specify that delivery shall be effected, and risk of loss and 
title to the Certificates shall pass, only upon proper delivery of the 
Certificates to the Exchange Agent and which shall be in a customary form) 
and (ii) instructions for use in effecting the surrender of the Certificates 
in exchange for certificates representing shares of Parent Common Stock. Upon 
surrender of a Certificate for cancellation to the Exchange Agent, together 
with such letter of transmittal, duly executed, and such other documents as 
may reasonably be required by the Exchange Agent, the holder of such 
Certificate shall be entitled to receive in exchange therefor a certificate 
evidencing that number of whole shares of Parent Common Stock which such 
holder has the right to receive in respect of the shares of Company Common 
Stock or Company Preferred Stock formerly evidenced by such Certificate 
(after taking into account all shares of Company Common Stock and Company 
Preferred Stock then held of record by such holder), cash in lieu of 
fractional shares of Parent Common Stock to which such holder is entitled 
pursuant to Section 2.02(e) and any dividends or other distributions to which 
such holder is entitled pursuant to Section 2.02(c), and the Certificate so 
surrendered shall forthwith be cancelled. In the event of a transfer of 
ownership of Company Common Stock or Company Preferred Stock which is not 
registered in the transfer records of the Company, a certificate representing 
the proper number of shares of Parent Common Stock may be issued to a person 
other than the person in whose name the Certificate so surrendered is 
registered, if such Certificate, accompanied by all documents required to 
evidence and effect such transfer, shall be properly endorsed or otherwise be 
in proper form for transfer and the person requesting such payment shall pay 
any transfer or other taxes required by reason of the issuance of shares of 
Parent Common Stock to a person other than the registered holder of such 
Certificate or establish to the satisfaction of Parent that such tax has been 
paid or is not applicable. Until surrendered as contemplated by this Section 
2.02, each Certificate shall be deemed at any time after the Effective Time 
to represent only the right to receive upon such surrender the certificate 
evidencing whole shares of Parent Common Stock, cash in lieu of any 
fractional shares of Parent Common Stock to which such holder is entitled 
pursuant to Section 2.02(e) and any dividends or other distributions to which 
such holder is entitled pursuant to Section 2.02(c). No interest will be paid 
or will accrue on any cash payable pursuant to Section 2.02(c) or 2.02(e). 

(c) Distributions with Respect to Unexchanged Shares. No dividends or other 
distributions declared or made after the Effective Time with respect to 
Parent Common Stock with a record date after the Effective Time
<PAGE>
<PAGE>
 
shall be paid to the holder of any unsurrendered Certificate with respect to 
the shares of Parent Common Stock represented thereby, and no cash payment in 
lieu of fractional shares shall be paid to any such holder pursuant to 
Section 2.02(e), in each case until the surrender of such Certificate in 
accordance with this Article II. Subject to the effect of applicable escheat 
laws, following surrender of such Certificate, there shall be paid to the 
holder of the certificate representing whole shares of Parent Common Stock 
issued in exchange therefor, without interest, (i) at the time of such 
surrender, the amount of any cash payable in lieu of a fractional share of 
Parent Common Stock to which such holder is entitled pursuant to Section 
2.02(e) and the amount of dividends or other distributions with a record date 
after the Effective Time theretofore paid with respect to such whole shares 
of Parent Common Stock, and (ii) at the appropriate payment date, the amount 
of dividends or other distributions with a record date after the Effective 
Time but prior to such surrender and with a payment date subsequent to such 
surrender payable with respect to such whole shares of Parent Common Stock. 

(d) No Further Ownership Rights in Company Stock. All shares of Parent Common 
Stock issued upon the surrender for exchange of Certificates in accordance 
with the terms of this Article II (including any cash paid pursuant to 
Section 2.02(c) or 2.02(e)) shall be deemed to have been issued (and paid) in 
full satisfaction of all rights pertaining to the shares of Company Common 
Stock and Company Preferred Stock theretofore represented by such 
Certificates, subject, however, to the Surviving Corporation's obligation to 
pay any dividends or make any other distributions with a record date prior to 
the Effective Time which may have been declared or made by the Company on 
such shares of Company Common Stock or Company Preferred Stock in accordance 
with the terms of this Agreement or prior to the date of this Agreement and 
which remain unpaid at the Effective Time and have not been paid prior to 
surrender. At the Effective Time, the stock transfer books of the Company 
shall be closed, and there shall be no further registrations of transfers of 
shares of Company Common Stock or Company Preferred Stock thereafter on the 
records of the Company. If, after the Effective Time, Certificates are 
presented to the Surviving Corporation, Parent or the Exchange Agent for any 
reason, they shall be cancelled and exchanged as provided in this Article II. 

(e) No Fractional Shares. (i) No certificates or scrip representing 
fractional shares of Parent Common Stock shall be issued upon the surrender 
for exchange of Certificates, and such fractional share interests will not 
entitle the owner thereof to vote or to any rights of a stockholder of 
Parent. 

(ii) As promptly as practicable following the Effective Time, Parent shall 
instruct the Exchange Agent to determine the excess of (x) the number of full 
shares of Parent Common Stock delivered to the Exchange Agent by Parent 
pursuant to Section 2.02(a) over (y) the aggregate number of full shares of 
Parent Common Stock to be distributed to holders of Certificates pursuant to 
Section 2.02(b) (such excess being herein called the "Excess Shares"). As 
soon after the Effective Time as practicable, the Exchange Agent, as agent 
for such holders of Certificates, shall sell the Excess Shares at the then 
prevailing prices on the NYSE, all in the manner provided in paragraph (iii) 
of this Section 2.02(e). 

(iii) The sale of the Excess Shares by the Exchange Agent shall be executed 
on the NYSE and shall be executed in round lots to the extent practicable. 
Until the net proceeds of such sale or sales have been distributed to such 
holders of Certificates, the Exchange Agent will hold such proceeds in trust 
for such holders of Certificates (the "Trust"). Parent shall pay all 
commissions, transfer taxes and other out-of-pocket transaction costs of the 
Exchange Agent incurred in connection with such sale or sales of Excess 
Shares. In addition, Parent shall pay the Exchange Agent's compensation and 
expenses in connection with such sales. The Exchange Agent shall determine 
the portion of the Trust to which each holder of one or more Certificates 
shall be entitled, if any, by multiplying the amount of the aggregate net 
proceeds comprising the Trust by a fraction the numerator of which is the 
amount of the fractional share interest to which such holder of Certificates 
is entitled (after taking into account all shares of Company Common Stock and 
Company Preferred Stock held of record immediately prior to the Effective 
Time by such holder) and the denominator of which is the aggregate amount of 
fractional share interests to which all holders of Certificates are entitled. 

(iv) As soon as practicable after the determination of the amount of cash, if 
any, to be paid to holders of Certificates with respect to any fractional 
share interests, the Exchange Agent shall promptly pay such amounts to such 
holders of Certificates subject to and in accordance with the terms of 
Section 2.02(c). 

(f) Termination of Exchange Fund and Trust. Any portion of the Exchange Fund 
and Trust that remains undistributed to the holders of Certificates for six 
months after the Effective Time shall be delivered to Parent, upon demand, 
and any holders of Certificates who have not theretofore complied with this 
Article II shall thereafter look only to Parent for the shares of Parent 
Common Stock, any cash in lieu of fractional shares of Parent Common Stock 
and any dividends or distributions with respect to Parent Common Stock to 
which they are entitled. 

(g) No Liability. None of Parent, Sub, the Company or the Exchange Agent 
shall be liable to any holder of shares of Company Common Stock or Company 
Preferred Stock for any shares of Parent Common Stock (or divi
<PAGE>
<PAGE>
 
dends or distributions with respect thereto) or cash from the Exchange Fund 
or the Trust delivered to a public official pursuant to any applicable 
abandoned property, escheat or similar law. 

(h) Withholding Rights. Parent or the Exchange Agent shall be entitled to 
deduct and withhold from the consideration otherwise payable pursuant to this 
Agreement to any holder of Certificates such amounts as Parent or the 
Exchange Agent, as the case may be, is required to deduct and withhold with 
respect to the making of such payment under the Code, or any provision of 
state, local or foreign tax law. To the extent that amounts are so withheld 
by Parent or the Exchange Agent, such withheld amounts shall be treated for 
all purposes of this Agreement as having been paid to the holder of the 
Certificates in respect of which such deduction and withholding shall have 
been made by Parent or the Exchange Agent. 

(i) Investment of Exchange Fund and Trust. The Exchange Agent shall invest 
any cash included in the Exchange Fund and the Trust, as directed by Parent, 
on a daily basis. Any interest and other income resulting from such 
investments shall be paid to Parent. 

                                 ARTICLE III 
                        REPRESENTATIONS AND WARRANTIES 

SECTION 3.01. Representations and Warranties of the Company. Except as set 
forth on the Disclosure Schedule delivered by the Company to Parent prior to 
the execution of this Agreement (the "Company Disclosure Schedule"), the 
Company represents and warrants to Parent and Sub as follows: 

  (a) Organization, Standing and Corporate Power. The Company and each of its 
subsidiaries is a corporation duly organized, validly existing and in good 
standing under the laws of the jurisdiction in which it is organized and has 
the requisite corporate power and authority to carry on its business as now 
being conducted. The Company and each of its subsidiaries is duly qualified 
or licensed to do business and is in good standing in each jurisdiction in 
which the nature of its business or the ownership or leasing of its 
properties makes such qualification or licensing necessary, other than in 
such jurisdictions where the failure to be so qualified or licensed 
(individually or in the aggregate) would not have a material adverse effect 
on the Company. The Company has delivered to Parent complete and correct 
copies of its certificate of incorporation and by-laws and the certificates 
of incorporation and by-laws or other organizational documents of its 
Material Subsidiaries, in each case as amended to the date of this Agreement. 
For purposes of this Agreement, "Material Subsidiary" means each subsidiary 
of the Company designated as a Material Subsidiary in Schedule 3.01(b)(i) of 
the Company Disclosure Schedule. 

  (b) Subsidiaries. Schedule 3.01(b)(i) of the Company Disclosure Schedule 
lists each subsidiary of the Company and its jurisdiction of incorporation or 
organization. All the outstanding shares of capital stock of each such 
subsidiary have been validly issued and are fully paid and nonassessable and 
are owned by the Company, by another subsidiary of the Company or by the 
Company and another such subsidiary, free and clear of all pledges, claims, 
liens, charges, encumbrances and security interests of any kind or nature 
whatsoever (collectively, "Liens") except as disclosed in Schedule 
3.01(b)(ii) of the Company Disclosure Schedule. Except for the capital stock 
of its subsidiaries, the Company does not own, directly or indirectly, any 
capital stock or other ownership interest in any corporation, partnership, 
joint venture or other entity except as disclosed in Schedule 3.01(b)(ii) of 
the Company Disclosure Schedule. 

  (c) Capital Structure. The authorized capital stock of the Company consists 
of 20,000,000 shares of Class A Common Stock, $.10 par value (the "Class A 
Stock"), 13,333,333 shares of Class B Common Stock, $.10 par value (the 
"Class B Stock"), 30,000,000 shares of Class C Common Stock, $.10 par value 
(the "Class C Stock" and, together with the Class A Stock and the Class B 
Stock, the "Company Common Stock") and 1,000,000 shares of preferred stock, 
$.10 par value. At the close of business on May 30, 1994, (i) 6,098,373 
shares of Class A Stock, 1,603,301 shares of Class B Stock, 8,995,262 shares 
of Class C Stock and 14,698 shares of Series E Convertible Preferred Stock 
("Company Preferred Stock") were issued and outstanding, (ii) there were no 
shares of Company Common Stock or shares of Company Preferred Stock held by 
the Company in its treasury, (iii) 1,603,301 shares of Class A Stock were 
reserved for issuance upon conversion of the Class B Stock and 557,527 shares 
of Class A Stock and 2,759,553 shares of Class C Stock were reserved for 
issuance upon exercise of outstanding Stock Options (as defined in Section 
5.04), (iv) 1,028,860 shares of Class A Stock and 1,028,860 shares of Class C 
Stock were reserved for issuance upon conversion of the Company Preferred 
Stock, (v) 512,280 shares of Class A Stock were reserved for issuance upon 
conversion of the Company's Convertible Subordinated Promissory Notes (the 
"Convertible Notes"), (vi) 120,709 shares of Class C Stock were reserved for 
issuance upon exercise of the Common Stock Purchase Warrants expiring May 31, 
1999 (the "Warrants"), (vii) 6,780 shares of Class A Stock and 6,780 shares 
of Class C Stock were
<PAGE>
<PAGE>
 
held by the Company in trust in connection with certain noncompete agreements 
to which the Company is a party (the "Noncompete Agreements") and (viii) 
1,028,860 shares of Class A Stock and 1,028,860 shares of Class C Stock were 
reserved for issuance upon conversion of the new Series F Convertible 
Preferred Stock which the Company had been considering exchanging on a 
share-for-share basis for the issued and outstanding Company Preferred Stock. 
The Company makes no representation or warranty that the number of shares 
reserved for issuance is not greater than the number of shares actually 
issuable upon the exercise of Stock Options or Warrants or upon the 
conversions or payments set forth above in (iii) through (viii). Except as 
set forth above, at the close of business on May 30, 1994, no shares of 
capital stock or other voting securities of the Company were issued, reserved 
for issuance or outstanding. There are no outstanding stock appreciation 
rights of the Company which were not granted in tandem with a related Stock 
Option and no outstanding limited stock appreciation rights or other rights 
to redeem for cash options or warrants of the Company. All outstanding shares 
of capital stock of the Company (including shares held in trust under the 
Noncompete Agreements) are, and all shares which may be issued upon the 
exercise of Stock Options or the Warrants or upon conversion of the Company 
Preferred Stock or the Convertible Notes will be, when issued, duly 
authorized, validly issued, fully paid and nonassessable and not subject to 
preemptive rights. Except for the Convertible Notes and Noncompete 
Agreements, there are no bonds, debentures, notes or other indebtedness of 
the Company having the right to vote (or convertible into, or exchangeable 
for, securities having the right to vote) on any matters on which 
stockholders of the Company may vote. Except for the right to convert Class B 
Stock into Class A Stock on a share-for-share basis, and as set forth above, 
as of the date of this Agreement, there are no outstanding securities, 
options, warrants, calls, rights, commitments, agreements, arrangements or 
undertakings of any kind to which the Company or any of its subsidiaries is a 
party or by which any of them is bound obligating the Company or any of its 
subsidiaries to issue, deliver or sell, or cause to be issued, delivered or 
sold, additional shares of capital stock or other voting securities of the 
Company or of any of its subsidiaries or obligating the Company or any of its 
subsidiaries to issue, grant, extend or enter into any such security, option, 
warrant, call, right, commitment, agreement, arrangement or undertaking. 
Except as provided in the Stock Option Plans which permit optionholders to 
pay the exercise price with Company Common Stock, there are no outstanding 
contractual obligations of the Company or any of its subsidiaries to 
repurchase, redeem or otherwise acquire any shares of capital stock (or 
options to acquire any such shares) of the Company or any of its 
subsidiaries. There are no agreements, arrangements or commitments of any 
character (contingent or otherwise) pursuant to which any person is or may be 
entitled to receive any payment based on the revenues, earnings or financial 
performance of the Company or any of its subsidiaries or assets or calculated 
in accordance therewith (other than ordinary course payments or commissions 
to sales representatives of the Company based upon revenues generated by them 
without augmentation as a result of the transactions contemplated hereby) or 
(except as disclosed in Schedule 3.01(c) of the Company Disclosure Schedule) 
to cause the Company or any of its subsidiaries to file a registration 
statement under the Securities Act of 1933 or which otherwise relate to the 
registration of any securities of the Company. 

  (d) Authority; Noncontravention. The Company has the requisite corporate 
power and authority to enter into this Agreement and, subject to the Company 
Stockholder Approval, to consummate the transactions contemplated by this 
Agreement. The execution and delivery of this Agreement by the Company and 
the consummation by the Company of the transactions contemplated by this 
Agreement have been duly authorized by all necessary corporate action on the 
part of the Company, subject to the Company Stockholder Approval of this 
Agreement. This Agreement has been duly executed and delivered by the Company 
and constitutes a valid and binding obligation of the Company, enforceable 
against the Company in accordance with its terms. The execution and delivery 
of this Agreement does not, and the consummation of the transactions 
contemplated by this Agreement and compliance with the provisions of this 
Agreement will not, 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, cancellation or acceleration of any obligation or to 
loss of a material benefit under, or result in the creation of any Lien upon 
any of the properties or assets of the Company or any of its subsidiaries 
under, (i) the certificate of incorporation or by-laws of the Company or the 
comparable charter or organizational documents of any of its subsidiaries, 
(ii) any loan or credit agreement, note, bond, mortgage, indenture, lease or 
other agreement, instrument, permit, concession, franchise or license 
applicable to the Company or any of its subsidiaries or their respective 
properties or assets or (iii) subject to the governmental filings and other 
matters referred to in the following sentence, any judgment, order, decree, 
statute, laws, ordinance, rule or regulation applicable to the Company or any 
of its subsidiaries or their respective properties or assets, other than, in 
the case of clauses (ii) or (iii), any such conflicts, violations, defaults, 
rights or Liens that individually or in the aggregate would not (x) have a 
material adverse effect on the Company, (y) impair in any material respect 
the ability of the Company to perform its obligations under this Agreement or 
(z) prevent or materially delay the consummation of any of the transactions 
contemplated by this Agreement. No consent, approval, order
<PAGE>
<PAGE>
 
or authorization of, or registration, declaration or filing with, any 
Federal, state or local government or any court, administrative or regulatory 
agency or commission or other governmental authority or agency, domestic or 
foreign (a "Governmental Entity"), is required by the Company or any of its 
subsidiaries in connection with the execution and delivery of this Agreement 
by the Company or the consummation by the Company of the transactions 
contemplated by this Agreement, except for (i) the filing with the Federal 
Trade Commission and the Antitrust Division of the Department of Justice (the 
"Specified Agencies") of a premerger notification and report form by the 
Company under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the 
"HSR Act"), (ii) the filing with the Securities and Exchange Commission (the 
"SEC") of (x) the Proxy Statement (as defined in Section 5.01) and (y) such 
reports under Section 13(a) of the Securities Exchange Act of 1934, as 
amended (the "Exchange Act"), as may be required in connection with this 
Agreement and the transactions contemplated by this Agreement, (iii) the 
filing of the Certificate of Merger with the Delaware Secretary of State and 
appropriate documents with the relevant authorities of other states in which 
the Company is qualified to do business and (iv) such other consents, 
approvals, orders, authorizations, registrations, declarations and filings 
the failure of which to be obtained or made would not, individually or in the 
aggregate, have a material adverse effect on the Company or prevent or 
materially delay the consummation of any of the transactions contemplated by 
this Agreement. 

  (e) SEC Documents; Financial Statements. Since January 1, 1992, the Company 
has filed with the SEC all required reports and forms and other documents 
(the "SEC Documents"). As of their respective dates, the SEC Documents 
complied in all material respects with the requirements of the Securities Act 
of 1933, as amended (the "Securities Act"), or the Exchange Act, as the case 
may be, and the rules and regulations of the SEC promulgated thereunder 
applicable to such SEC Documents, and none of the SEC Documents con- tained 
any untrue statement of a material fact or omitted to state a material fact 
required to be stated therein or necessary in order to make the statements 
therein, in light of the circumstances under which they were made, not 
misleading. Except to the extent that information contained in any SEC 
Document has been revised or superseded by a later-filed SEC Document filed 
and publicly available prior to the date of this Agreement, none of the SEC 
Documents contains any untrue statement of a material fact or omits to state 
any material fact required to be stated therein or necessary in order to make 
the statements therein, in light of the circumstances under which they were 
made, not misleading. The financial statements of the Company included in the 
SEC Documents comply as to form in all material respects with applicable 
accounting requirements and the published rules and regulations of the SEC 
with respect thereto, have been prepared in accordance with generally 
accepted accounting principles (except, in the case of unaudited statements, 
as permitted by Form 10-Q of the SEC) applied on a consistent basis during 
the periods involved (except as may be indicated in the notes thereto) and 
fairly present the consolidated financial position of the Company and its 
consolidated subsidiaries as of the dates thereof and the consolidated 
results of their operations and cash flows for the periods then ended 
(subject, in the case of unaudited statements, to normal year-end audit 
adjustments). Except as set forth in the SEC Documents filed prior to the 
date of this Agreement (or, with respect to any future repetition of this 
representation, prior to the time of such repetition), and except for 
liabilities and obligations incurred in the ordinary course of business 
consistent with past practice since the date of the most recent consolidated 
balance sheet included in the SEC Documents, neither the Company nor any of 
its subsidiaries has any liabilities or obligations of any nature (whether 
accrued, absolute, contingent or otherwise) required by generally accepted 
accounting principles to be set forth on a consolidated balance sheet of the 
Company and its consolidated subsidiaries or in the notes thereto. 

  (f) Information Supplied. None of the information supplied or to be 
supplied by the Company specifically for inclusion or incorporation by 
reference in (i) the Form S-4 (as defined in Section 5.01(a)) will, at the 
time the Form S-4 is filed with the SEC, at any time it is amended or 
supplemented or at the time it becomes effective under the Securities Act, 
contain any untrue statement of a material fact or omit to state any material 
fact required to be stated therein or necessary to make the statements 
therein not misleading or (ii) the Proxy Statement will, at the date it is 
first mailed to the Company's stockholders or at the time of the Company 
Stockholders' Meeting (as defined in Section 5.01(b)), 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 
Proxy Statement will comply as to form in all material respects with the 
requirements of the Exchange Act and the rules and regulations thereunder, 
except that no representation or warranty is made by the Company with respect 
to statements made or incorporated by reference therein based on information 
supplied by Parent or Sub specifically for inclusion or incorporation by 
reference in the Proxy Statement. 

  (g) Absence of Certain Changes or Events. Except as disclosed in the SEC 
Documents filed prior to the date of this Agreement, since January 1, 1994, 
the Company has conducted its business only in the ordinary
<PAGE>
<PAGE>
 
course consistent with prior practice, and there has not been (i) any 
material adverse change in the Company and its subsidiaries on a consolidated 
basis, (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, (iii) any split, combination or 
reclassification of any of its capital stock or any issuance or the 
authorization of any issuance of any other securities in respect of, in lieu 
of or in substitution for shares of its capital stock, (iv) (x) any granting 
by the Company or any of its subsidiaries to any officer, general manager or 
laboratory manager of the Company or any of its subsidiaries of any increase 
in compensation, except in the ordinary course of business consistent with 
prior practice or as was required under employment agreements in effect as of 
the date of the most recent audited financial statements included in the SEC 
Documents filed prior to the date of this Agreement (a list of all such 
employment agreements being set forth in Section 3.01(g) of the Company

Schedule, as of the date of this Agreement there is no suit, action,

1974, as amended ("ERISA")) (sometimes referred to herein as "Pension 
Plans"), "employee welfare benefit plans" (as defined in Section 3(1) of 
ERISA) and all other Benefit Plans currently maintained, or contributed to, 
or required to be maintained or contributed to, with the Company or any other 
person or entity that, together with the Company, is treated as a single 
employer under Section 414(b), (c), (m) or (o) of the Code (each a "Commonly 
Controlled Entity"), including all employment, termination, severance, or 
other contracts for the benefit of any current or former employees, officers 
or directors of the Company or any of its subsidiaries. The Company has 
delivered to Parent true, complete and correct copies of (v) the most recent

tion is required, (y) the most recently received Internal Revenue Service 
determination letter for each such Benefit Plan and (z) each trust agreement 
and group annuity contract relating to any such Benefit Plan. 

  (ii) Each of the Company's and its subsidiaries' Benefit Plans has been 
administered in all material respects in accordance with its terms. The 
Company, each of its subsidiaries and all such Benefit Plans are all in 
compliance in all material respects with applicable provisions of ERISA and 
the Code. 

  (iii)  All of the Company's and its subsidiaries' Pension Plans intended to 
be qualified under Section 401(a) of the Code have been the subject of 
determination letters from the Internal Revenue Service to the effect that 
such Pension Plans are qualified and exempt from Federal income taxes under 
Section 401(a) and 501(a), respectively, of the Code and no such 
determination letter has been revoked nor, to the knowledge of the Company, 
has revocation been threatened, nor has any such Pension Plan been amended 
since the date of its most recent determination letter or application 
therefor in any respect except for any of the foregoing which could 
reasonably be expected to result in a material adverse effect on the Company. 

  (iv) No Pension Plan that the Company or any of its subsidiaries maintains 
is subject to Title IV of ERISA. 

  (v) None of the Company, any of its subsidiaries, any officer of the 
Company or any of its subsidiaries or any of its Benefit Plans which are 
subject to ERISA, including its Pension Plans, any trusts created thereunder 
or any trustee or administrator thereof, has engaged in a non-exempt 
"prohibited transaction" (as such term is defined in Section 406 of ERISA or 
Section 4975 of the Code) or any other breach of fiduciary responsibility 
that could subject the Company, or any of its subsidiaries or any officer of 
the Company or any of its subsidiaries to tax or penalty under ERISA, the 
Code or other applicable law that could result in a material adverse effect 
on the Company. Neither any of such Benefit Plans nor any of such trusts has 
been terminated, nor has there been any "reportable event" (as that term is 
defined in Section 4043 of ERISA) with respect thereto, during the last five 
years. 

  (vi) Except as disclosed in Schedule 3.01(j), the consummation of the 
transactions contemplated by this Agreement will not result in an increase in 
the amount of compensation or benefits or accelerate the vesting or timing of 
payment of any benefits payable to or in respect of any employee or former 
employee of the Company or any subsidiary of the Company or the beneficiary 
or dependent of any such employee or former employee. 

  (vii) With respect to any of the Company's or any of its subsidiaries' 
Benefit Plans that is an employee welfare benefit plan, (except as disclosed 
in Schedule 4.01), (x) no such Benefit Plan is funded through a "welfare 
benefit fund", as such term is defined in Section 419(e) of the Code, (y) 
each such Benefit Plan that is a "group health plan", as such term is defined 
in Section 5000(b)(1) of the Code, complies with the applicable requirements 
of Section 4980B(f) of the Code except where the failure to so comply could 
not reasonably be expected to result in a material adverse effect on the 
Company and (z) each such Benefit Plan (including any such Benefit Plan 
covering retirees or other former employees) may be amended or terminated 
without resulting in a material adverse effect on the Company on or at any 
time after the Effective Time. 

  (viii) No Commonly Controlled Entity has incurred any material liability to 
a Pension Plan of the Company or any of its subsidiaries (other than for 
contributions not yet due). 

  (k) Taxes. (i) Each of the Company and its subsidiaries has timely filed 
all Federal, state, local and foreign tax returns and reports required to be 
filed by it through the date hereof and shall timely file all such returns 
and reports required to be filed on or before the Effective Time. All such 
returns and reports are and will be true, complete and correct in all 
material respects. The Company and each of its subsidiaries has paid and 
discharged (or the Company has paid and discharged on its behalf) all taxes 
due from them, other than such taxes as are being contested in good faith by 
appropriate proceedings and are adequately reserved for on the most recent 
financial statements contained in the SEC Documents filed prior to the date 
of the Agreement. The most recent financial statements contained in the SEC 
Documents filed prior to the date of this Agreement properly reflect in 
accordance with generally accepted accounting principles all taxes payable by 
the Company and its subsidiaries for all taxable periods and portions thereof 
through the date of such financial statements. 

  (ii) Except as disclosed in Schedule 3.01(k) of the Company Disclosure 
Schedule, no claim or deficiency for any taxes has been proposed, threatened, 
asserted or assessed by the Internal Revenue Service or any other taxing 
authority or agency against the Company, or any of its subsidiaries which, if 
resolved against the Company or any of its subsidiaries, would, individually 
or in the aggregate, have a material adverse effect upon
<PAGE>
<PAGE>
 
the Company, and no requests for waivers of the time to assess any taxes are 
pending. The Federal income tax returns of the Company and each of its 
subsidiaries consolidated in such returns have been examined by and settled 
with the Internal Revenue Service for all years through 1990, except as 
disclosed in Schedule 3.01(k) of the Company Disclosure Schedule. 

  (iii) Neither the Company nor any of its subsidiaries has taken or agreed 
to take any action or has any knowledge of any fact or circumstance that is 
reasonably likely to prevent the Merger from qualifying as a reorganization 
within the meaning of Section 368(a)(1)(A) and (a)(2)(E) of the Code. 

  (iv) As used in this Agreement, "taxes" shall include all Federal, state, 
local and foreign income, property, sales, excise and other taxes, of any 
nature whatsoever (whether payable directly or by withholding), together with 
any interest and penalties, additions to tax or additional amounts imposed 
with respect thereto. Notwithstanding the definition of "subsidiary" set 
forth in Section 8.03 of this Agreement, for the purposes of this Section 
3.01(k), references to the Company and each of its subsidiaries shall include 
former subsidiaries of the Company for the periods during which any such 
corporations were included in the consolidated Federal income tax return of 
the Company. 

  (l) No Excess Parachute Payments. Any amount that could be received 
(whether in cash or property or the vesting of property) as a result of any 
of the transactions contemplated by this Agreement by any employee, officer 
or director of the Company or any of its affiliates who is a "disqualified 
individual" (as such term is defined in proposed Treasury Regulation Section 
1.280G-1) under any employment, severance or termination agreement, other 
compensation arrangement or Benefit Plan currently in effect would not, 
except as may otherwise have been disclosed to Parent prior to the date of 
this Agreement, be characterized as an "excess parachute payment" (as such 
term is defined in Section 280G(b)(l) of the Code). 

  (m) Compliance with Applicable Laws.  (i) Each of the Company and its 
subsidiaries has in effect all Federal, state, local and foreign governmental 
approvals, authorizations, certificates, filings, franchises, licenses, 
notices, permits and rights ("Permits") necessary for it to own, lease or 
operate its properties and assets and to carry on its business as now 
conducted, and there has occurred no default under any such Permit, except 
for the lack of Permits and for defaults under Permits which lack or default 
individually or in the aggregate would not have a material adverse effect on 
the Company. Except as disclosed in the SEC Documents filed prior to, or as 
otherwise disclosed to Parent prior to, the date of this Agreement, the 
Company and its subsidiaries are in compliance with all applicable statutes, 
laws, ordinances, rules, orders and regulations of any Governmental Entity, 
except for noncompliance which individually or in the aggregate would not 
have a material adverse effect on the Company. 

  (ii) To the knowledge of the Company, the Company and each of its 
subsidiaries is, and has been, and each of the Company's former subsidiaries, 
while subsidiaries of the Company, was, in compliance in all material 
respects with all applicable Environmental Laws, except for noncompliance 
which individually or in the aggregate would not have a material adverse 
effect on the Company. The term "Environmental Laws" means any Federal, 
state, local or foreign statute, code, ordinance, rule, regulation, policy, 
guideline, permit, consent, approval, license, judgment, order, writ, decree, 
injunction or other authorization, including the requirement to register 
underground storage tanks, relating to: (A) emissions, discharges, releases 
or threatened releases of Hazardous Material (as hereinafter defined) into 
the environment, including, without limitation, into ambient air, soil, 
sediments, land surface or subsurface, buildings or facilities, surface 
water, groundwater, publicly owned treatment works, septic systems or land; 
or (B) the generation, treatment, storage, disposal, use, handling, 
manufacturing, transportation or shipment of Hazardous Material. 

  (iii) During the period of ownership or operation by the Company and its 
subsidiaries of any of their respective current or previously owned or leased 
properties, there have been no releases of Hazardous Material in, on, under 
or affecting such properties or, to the knowledge of the Company, any 
surrounding site, except in each case for those which individually or in the 
aggregate are not reasonably likely to have a material adverse effect on the 
Company. Prior to the period of ownership or operation by the Company and its 
subsidiaries of any of their respective current or previously owned or leased 
properties, to the knowledge of the Company, no Hazardous Material was 
generated, treated, stored, disposed of, used, handled or manufactured at, or 
transported, shipped or disposed of from, such currently or previously owned 
or leased properties, and there were no releases of Hazardous Material in, 
on, under or affecting any such property or any surrounding site, except in 
each case for those which individually or in the aggregate are not reasonably 
likely to have a material adverse effect on the Company. The term "Hazardous 
Material" means (A) hazardous materials, contaminants, constituents, medical 
wastes, hazardous or infectious wastes and hazardous substances as those 
terms are defined in the following statutes and their implementing 
regulations: the Hazardous Materials Transportation Act, 49

  (n) State Takeover Statutes. The Company has taken all requisite action to 
render inapplicable to this Agreement and the Significant Stockholder 
Agreement and the transactions contemplated hereby and thereby the provisions 
of Section 203 of the DGCL and such action is effective at the date of this 
Agreement. To the best of the Company's knowledge, no other state takeover 
statute or similar statute or regulation (including, without limitation, 
Section 2115 of the California General Corporation Law) applies or purports 
to apply to the Merger, this Agreement or any of the transactions 
contemplated by this Agreement or the Significant Stockholder Agreements. 

  (o) Brokers. No broker, investment banker, financial advisor or other 
person, other than Peter J. Solomon Securities Company Limited and CS First 
Boston Corporation, the aggregate fees and expenses of which have been 
disclosed to Parent and will be paid by the Company, is entitled to any 
broker's, finder's, financial advisor's or other similar fee or commission in 
connection with the transactions contemplated by this Agreement based upon 
arrangements made by or on behalf of the Company. 

  (p) Opinion of Financial Advisor. The Company has received the opinion of 
CS First Boston Corporation, dated the date of this Agreement, to the effect 
that, as of such date, the consideration to be received in the Merger by the 
Company's stockholders is fair to each class of the Company's stockholders 
from a financial point of view, and a signed copy of such opinion has been 
delivered to Parent. 

  (q) Contracts; Debt Instruments. Except as disclosed in the SEC Documents 
filed prior to the date of this Agreement, there is no contract or agreement 
that is material to the business, financial condition or results of 
operations of the Company and its subsidiaries taken as a whole and neither 
the Company nor any of its subsidiaries is in violation of or in default 
under (nor does there exist any condition which upon the passage of time or 
the giving of notice, or both, would cause such a violation of or default 
under) any loan or credit agreement, note, bond, mortgage, indenture or 
lease, or any other contract, agreement, arrangement or understanding, to 
which it is a party or by which it or any of its properties or assets is 
bound, except for violations or defaults that could not, individually or in 
the aggregate, reasonably be expected to result in a material adverse effect 
on the Company. Set forth in Section 3.01 (q) of the Company Disclosure 
Schedule is a description of any material changes to the amount and terms of 
the indebtedness of the Company and its subsidiaries as described in the 
Company's Form 10-K for the year ended December 31, 1993. 

  (r) Title to Properties. (i) The Company and its subsidiaries have good and 
marketable title to, or valid leasehold interests in, all their material 
properties and assets except for such as are no longer used or useful in the 
conduct of their businesses or as have been disposed of in the ordinary 
course of business and except for defects in title, easements, restrictive 
covenants and similar encumbrances or impediments that, individually or in 
the aggregate, would not have a material adverse effect on the Company. 

  (ii) Each of the Company and its subsidiaries has complied with the terms 
of all material leases to which it is a party and under which it is in 
occupancy, and all such leases are in full force and effect, except for such 
failures to comply or to be in full force and effect which would not, 
individually or in the aggregate, have a material adverse effect on the 
Company. Each of the Company and its subsidiaries enjoys peaceful and 
undisturbed possession under all such material leases, except for the 
failures to do so which would not, individually or in the aggregate, have a 
material adverse effect on the Company. 

  (s) Accounting Matters.  Neither the Company nor, to its best knowledge, 
any of its affiliates have taken or agreed to take any action or is aware of 
any condition that would prevent Parent from accounting for the business 
combination to be effected by the Merger as a pooling-of-interests. 

  (t) Voting Requirements. The Company Stockholder Approval is the only vote 
of the holders of any class or series of the Company's securities necessary 
to approve this Agreement and the transactions contemplated by this 
Agreement. Assuming that those matters relating to Parent set forth in 
Schedule 3.01(t) are true and correct, the affirmative vote of the 
Significant Stockholder in accordance with the Significant Stockholder 
Agreement is sufficient and adequate, without the approval of any other 
stockholder of the Company, to approve this Agreement and the transactions 
contemplated hereby for all purposes under the DGCL and the Company's 
certificate of incorporation and by-laws.

(u) Noncompetition. Except as set forth in Schedule 3.01(u) of the Company 
Disclosure Schedule, the Company and its subsidiaries are not, and after the 
Effective Time neither the Surviving Corporation nor Parent will be (by 
reason of any agreement to which the Company is a party), subject to any 
noncompetition or similar restriction on their respective businesses. 

  (v) Intellectual Property.  The Company and each of its Material 
Subsidiaries owns or possesses adequate and enforceable licenses or other 
rights to use all patents, trade secrets, trade names, trademarks, inventions 
and processes used in the business of the Company or such Material Subsidiary 
as currently conducted and has not received any notice of conflict which 
asserts the rights of others with respect thereto (except for such failures 
to comply with the foregoing representations as would not, individually or in 
the aggregate, have a material adverse effect on the Company). The Company 
and each of its Material Subsidiaries has performed all the obligations 
required to be performed by it and is not in default under any agreement 
relating to any of the foregoing (except for such failures to perform or such 
defaults as would not, individually or in the aggregate, result in a material 
adverse effect on the Company). 

SECTION 3.02. Representations and Warranties of Parent and Sub. Except as set 
forth on the Disclosure Schedule delivered by Parent to the Company prior to 
the execution of this Agreement (the "Parent Disclosure Schedule"), Parent 
and Sub represent and warrant to the Company as follows: 

  (a) Organization, Standing and Corporate Power. Each of Parent and each of 
its subsidiaries (including Sub) is a corporation duly organized, validly 
existing and in good standing under the laws of the jurisdiction in which it 
is incorporated and has the requisite corporate power and authority to carry 
on its business as now being conducted. Each of Parent and each of its 
subsidiaries (including Sub) is duly qualified or licensed to do business and 
is in good standing in each jurisdiction in which the nature of its business 
or the ownership or leasing of its properties makes such qualification or 
licensing necessary, other than in such jurisdictions where the failure to be 
so qualified or licensed (individually or in the aggregate) would not have a 
material adverse effect on Parent. Parent has delivered to the Company 
complete and correct copies of its certificate of incorporation and by-laws 
and the certificate of incorporation and by-laws of Sub, in each case as 
amended to the date of this Agreement. 

  (b) Capital Structure. The authorized capital stock of Parent consists of 
500,000,000 shares of Parent Common Stock and 10,000,000 shares of Series 
Preferred Stock, par value $100 per share (of which 600,000 shares have been 
designated Series A Junior Participating Preferred Stock (the "Series A 
Preferred Stock") and 316,822 shares have been designated Series B Cumulative 
Convertible Preferred Stock (the "Series B Preferred Stock")). At the close 
of business on April 18, 1994, (i) 208,963,513 shares of Parent Common Stock, 
no shares of Series A Preferred Stock and 259,631 shares of Series B 
Preferred Stock were issued and outstanding, (ii) 27,464,921 shares of Parent 
Common Stock were held by Parent in its treasury and (iii) 8,592,297 shares 
of Parent Common Stock were reserved for issuance upon exercise of 
outstanding employee stock options to purchase shares of Parent Common Stock. 
Each share of Parent Common Stock carries with it a preferred share purchase 
right (a "Right") which entitles the holder thereof to purchase, on the 
occurrence of certain events, Parent Common Stock or Series A Preferred 
Stock. Except as set forth above, at the close of business on April 18, 1994 
no shares of capital stock or other voting securities of the Parent were 
issued, reserved for issuance or outstanding. All outstanding shares of 
capital stock of Parent are, and all shares which may be issued pursuant to 
this Agreement will be, when issued, duly authorized, validly issued, fully 
paid and nonassessable and not subject to preemptive rights. There are no 
bonds, debentures, notes or other indebtedness of Parent having the right to 
vote (or convertible into, or exchangeable for, securities having the right 
to vote) on any matters on which stockholders of Parent may vote. Except as 
set forth above, and except for employee stock options granted in the 
ordinary course of business since April 18, 1994, as of the date of this 
Agreement, there are no outstanding securities, options, warrants, calls, 
rights, commitments, agreements, arrangements or undertakings of any kind to 
which Parent or any of its Significant Subsidiaries is a party or by which 
any of them is bound obligating Parent or any of its Significant Subsidiaries 
to issue, deliver or sell, or cause to be issued, delivered or sold, 
additional shares of capital stock or other voting securities of Parent or of 
any of its Significant Subsidiaries or obligating Parent or any of its 
Significant Subsidiaries to issue, grant, extend or enter into any such 
security, option, warrant, call, right, commitment, agreement, arrangement or 
undertaking. There are no outstanding contractual obligations of Parent or 
any of its Significant Subsidiaries to repurchase, redeem or otherwise 
acquire any shares of capital stock of Parent or its Significant 
Subsidiaries. As of the date of this Agreement, the authorized capital stock 
of Sub consists of 500 shares of common stock, par value $.01 per share, of 
which one share has been validly issued, is fully paid and nonassessable and 
is owned by Parent free and clear of any Liens. For purposes of this 
Agreement, "Significant Subsidiary" means any subsidiary that constitutes a 
significant subsidiary within the meaning of Rule 1-02 of Regulation S-X of 
the SEC.

(c) Authority; Noncontravention. Parent and Sub have the requisite 
corporate power and authority to enter into this Agreement and to consummate 
the transactions contemplated by this Agreement. The execution and delivery 
of this Agreement and the consummation of the transactions contemplated by 
this Agreement have been duly authorized by all necessary corporate action on 
the part of Parent and Sub. This Agreement has been duly executed and 
delivered by Parent and Sub and constitutes a valid and binding obligation of 
each such party, enforceable against each such party in accordance with its 
terms. The execution and delivery of this Agreement does not, and the 
consummation of the transactions contemplated by this Agreement and 
compliance with the provisions of this Agreement will not, 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, cancellation or 
acceleration of any obligation or to loss of a material benefit under, or 
result in the creation of any Lien upon any of the properties or assets of 
Parent or any of its subsidiaries under, (i) the certificate of incorporation 
or by-laws of Parent or Sub or the comparable charter or organizational 
documents of any other subsidiary, of Parent, (ii) any loan or credit 
agreement, note, bond, mortgage, indenture, lease or other agreement, 
instrument, permit, concession, franchise or license applicable to Parent or 
any of its subsidiaries or their respective properties or assets or (iii) 
subject to the governmental filings and other matters referred to in the 
following sentence, any judgement, order, decree, statute, law, ordinance, 
rule or regulation applicable to Parent or any of its subsidiaries or their 
respective properties or assets, other than, in the case of clauses (ii) or 
(iii), any such conflicts, violations, defaults, rights or Liens that 
individually or in the aggregate would not (x) have a material adverse effect 
on Parent, (y) impair in any material respect the ability of Parent and Sub 
to perform their respective obligations under this Agreement or (z) prevent 
or materially delay the consummation of any of the transactions contemplated 
by this Agreement. No consent, approval, order or authorization of, or 
registration, declaration or filing with any Governmental Entity is required 
by Parent or any of its subsidiaries in connection with the execution and 
delivery of this Agreement or the consummation by Parent or Sub, as the case 
may be, of any of the transactions contemplated by this Agreement, except for 
(i) the filing with the Specified Agencies of a premerger notification and 
report form under the HSR Act, (ii) the filing with the SEC of (x) the Form 
S-4 and (y) such reports under Sections 13(a), 13(d) and 16(a) of the 
Exchange Act as may be required in connection with this Agreement and the 
transactions contemplated by this Agreement, (iii) the filing of the 
Certificate of Merger with the Delaware Secretary of State and appropriate 
documents with the relevant authorities of other states in which the Company 
is qualified to do business and (iv) such other consents, approvals, orders, 
authorizations, registrations, declarations and filings, including under (x) 
the laws of any foreign country in which the Company or any of its 
subsidiaries conducts any business or owns any property or assets or (y) the 
"takeover" or "blue sky" laws of various states, the failure of which to be 
obtained or made would not, individually, or in the aggregate, have a 
material adverse effect on Parent or prevent or materially delay the 
consummation of any of the transactions contemplated by this Agreement. 

  (d) SEC Documents; Financial Statements. Since January 1, 1992, Parent has 
filed with the SEC all required reports and forms and other documents (the 
"Parent SEC Documents"). As of their respective dates, the Parent SEC 
Documents complied in all material respects with the requirements of the 
Securities Act or the Exchange Act, as the case may be, and the rules and 
regulations of the SEC promulgated thereunder applicable to such Parent SEC 
Documents, and none of the Parent SEC Documents contained any untrue 
statement of a material fact or omitted to state a material fact required to 
be stated therein or necessary in order to make the statements therein, in 
light of the circumstances under which they were made, not misleading. Except 
to the extent that information contained in any Parent SEC Document has been 
revised or superseded by a later-filed Parent SEC Document filed and publicly 
available prior to the date of this Agreement, none of the Parent SEC 
Documents contains any untrue statement of a material fact or omits to state 
any material fact required to be stated therein or necessary in order to make 
the statements therein, in light of the circumstances under which they were 
made, not misleading. The financial statements of Parent included in the 
Parent SEC Documents comply as to form in all material respects with 
applicable accounting requirements and the published rules and regulations of 
the SEC with respect thereto, have been prepared in accordance with generally 
accepted accounting principles (except, in the case of unaudited statements, 
as permitted by Form 10-Q of the SEC) applied on a consistent basis during 
the periods involved (except as may be indicated in the notes thereto) and 
fairly present the consolidated financial position of Parent and its 
consolidated subsidiaries as of the dates thereof and the consolidated 
results of their operations and cash flows for the periods then ended 
(subject, in the case of unaudited statements, to normal year-end 
adjustments). Except as set forth in the Parent SEC Documents, and except for 
liabilities and obligations incurred in the ordinary course of business 
consistent with past practice since the date of the most recent consolidated 
balance sheet included in the Parent SEC Documents, neither Parent nor any of 
its subsidiaries has any material liabilities or obligations of any nature 
(whether
<PAGE>
<PAGE>

adverse change in Parent, (ii) except for regular quarterly cash dividends

effect on Parent, (ii) impair in any material respect the ability of Parent 
to perform its obligations under this Agreement or (iii) prevent the 
consummation of any of the transactions contemplated by this Agreement, nor 
is there any judgment, decree, injunction, rule or order of any Governmental

material respects. Parent and each of its subsidiaries has paid and 
discharged (or Parent has paid and discharged on its behalf) all taxes due 
from them, other than such taxes as are being contested in good faith by 
appropriate proceedings and are adequately reserved for on the most recent 
financial statements contained in the SEC Documents filed prior to the date

asserted or assessed by the Internal Revenue Service or any other taxing 
authority or agency against Parent or any of its subsidiaries which, if

reasonably likely to prevent the Merger from qualifying as a reorganization 
within the meaning of Section 368(a)(1)(A) and (a)(2)(E) of the Code. 

  (i) Compliance with Applicable Laws. (i) Each of Parent and its 
subsidiaries has in effect all Permits necessary for it to own, lease or

of Permits and for defaults under Permits which lack or default individually 
or in the aggregate would not have a material adverse effect on Parent. 
Except as disclosed in the Parent SEC Documents filed prior to the date of

Governmental Entity, except for possible noncompliance which individually or

or affecting such properties or, to the knowledge of Parent, any surrounding 
site, except in each case for those which individually or in the aggregate 
are not reasonably likely to have a material adverse effect on Parent. Prior 
to the period of ownership or operation by Parent and its subsidiaries of any 
of their respective current or previously owned or leased properties, to the 
knowledge of Parent, no Hazardous Material was generated, treated, stored, 
disposed of, used, handled or manufactured at, or transported, shipped or 
disposed of from, such current or previously owned or leased properties, and 
there were no releases of Hazardous Material in, on, under or affecting any 
such property or any surrounding site, except in each case for those which 
individually or in the aggregate are not reasonably likely to have a material 
adverse effect on Parent. 

  (j) Brokers. No broker, investment banker, financial advisor or other 
person, other than Lazard Freres & Co., the fees and expenses of which will 
be paid by Parent, is entitled to any broker's, finder's, financial advisor's 
or other similar fee or commission in connection with the transactions 
contemplated by this Agreement based upon arrangements made by or on behalf 
of Parent or Sub. 

  (k) Opinion of Financial Advisor. Parent has received the opinion of Lazard 
Freres & Co., dated the date of this Agreement, to the effect that, as of 
such date, the consideration to be paid by Parent in the Merger is fair to 
Parent and the stockholders of Parent from a financial point of view, and a 
signed copy of such opinion has been delivered to the Company. 

  (l) Contracts; Debt Instruments. Except as disclosed in the Parent SEC 
Documents filed prior to the date of this Agreement, there are no contracts 
or agreements that are material to the business, financial condition or 
results of operations of Parent and neither Parent nor any of its 
subsidiaries is in violation of or in default under (nor does there exist any

agreement, note, bond, mortgage, indenture or lease or other contract 
agreement, arrangement or understanding, to which it is a party or by which 
it or any of its properties or assets is bound, except for violations or 
defaults that could not, individually or in the aggregate, reasonably be 
expected to result in a material adverse effect on Parent. Set forth in

subsidiaries as described in Parent's Form 10-K for the year ended January 2,

marketable title to, or valid leasehold interests in, all their material 
properties and assets except for such as are no longer used or useful in the 
conduct of their businesses or as have been disposed of in the ordinary 
course of business and except for defects in title, easements, restrictive 
covenants and similar encumbrances or impediments that, individually or in 
the aggregate, would not have a material adverse effect on Parent. All such 
material properties and assets, other than properties and assets in which 
Parent or any of its subsidiaries has leasehold interests, are free and clear 
of all Liens, except for Liens that, individually or in the aggregate, would 
not have a material adverse effect on Parent. 

  (ii) Each of Parent and its subsidiaries has complied with the terms of all 
material leases to which it is a party and under which it is in occupancy, 
and all such leases are in full force and effect, except for such failures to 
comply or to be in full force and effect which would not, individually or in 
the aggregate, have a material adverse effect on Parent. Each of Parent and 
its subsidiaries enjoys peaceful and undisturbed possession under all such 
material leases, except for the failures to do so which would not, 
individually or in the aggregate, have a material adverse effect on Parent. 

  (n) Accounting Matters. Neither Parent nor, to its best knowledge, any of 
its affiliates have taken or agreed to take any action or has knowledge of 
any fact or circumstance relating to Parent that would prevent Parent from 
accounting for the business combination to be effected by the Merger as a 
pooling-of-interests.

engaging in the transactions contemplated hereby, has engaged in no other

or kind whatsoever or entered into any agreements or arrangements with any 
person.

SECTION 4.02. No Solicitation. (a) In light of the consideration given by the 
Board of Directors of the Company prior to the execution of this Agreement 
to, among other things, the transactions contemplated hereby and by the 
requirement of Parent that the Significant Stockholder Agreement be executed 
concurrently herewith as a condition of Parent entering into this Agreement, 
and to various alternatives to the transactions contemplated by this 
Agreement, and in light of the fairness opinion described in Section 3.01(p) 
and the information provided to the Company by its financial advisor, Peter 
J. Solomon Securities Company Limited, regarding potential alternative 
opportunities for the sale of the Company, the Company agrees that it shall 
not, nor shall it permit any of its subsidiaries to, nor shall it authorize 
or permit any officer, director or employee of, or any investment banker, 
attorney or other advisor or representative of, the Company or any of its 
subsidiaries to, solicit or initiate, or encourage the submission of, any

regarding, or furnish to any person any information with respect to, or take 
any other action to facilitate any inquiries or the making of any proposal 
that constitutes, or may reasonably be expected to lead to, any Takeover 
Proposal. For purposes of this Agreement, "Takeover Proposal" means any 
proposal (whether or not in writing and whether or not delivered to the 
Company's stockholders generally) for a merger or other business combination 
involving the Company or any of its Material Subsidiaries or any proposal or 
offer to acquire in any manner, directly or indirectly, an equity interest 
in, any voting securities of, or a substantial portion of the assets of the 
Company or any of its Material Subsidiaries, other than the transactions 
contemplated by this Agreement. Nothing contained herein shall prohibit the 
Company from taking and disclosing to its stockholders a position 
contemplated by Rule 14e-2(a) under the Exchange Act with respect to a 
Takeover Proposal by means of a tender offer. 

(b) The Company shall promptly advise Parent orally and in writing of any 
request for information or of any Takeover Proposal, or any inquiry with 
respect to or which could lead to any Takeover Proposal, the material terms 
and conditions of such request, Takeover Proposal or inquiry, and the 
identity of the person making any such Takeover Proposal or inquiry. The 
Company shall keep Parent informed of the status and details of any such 
request, Takeover Proposal or inquiry.

supplements thereof or supplements thereto, the "Proxy Statement"), and (ii) 
Parent shall prepare and file with the SEC a registration statement on Form 
S-4 (together with all amendments thereto, the "Form S-4") in which the Proxy 
Statement shall be included as a prospectus, in connection with the 
registration under the Securities Act of the shares of Parent Common Stock to 
be issued to the stockholders of the Company pursuant to the Merger. Each of 
Parent and the Company shall use all reasonable efforts to cause the Form S-4 
to become effective as promptly as practicable, and shall take all or any 
action required under any applicable Federal or state securities laws in 
connection with the issuance of shares of Parent Common Stock pursuant to the 
Merger. Each of Parent and the Company shall furnish all information 
concerning itself to the other as the other may reasonably request in

Statement. As promptly as practicable after the Form S-4 shall have become 
effective, the Company shall mail the Proxy Statement to its stockholders. 

(b) Stockholders' Meeting.  As soon as practicable following the date of this 
Agreement, the Company shall call and hold a meeting of its stockholders (the 
"Company Stockholders' Meeting"), for the purpose of obtaining the Company

from its stockholders proxies, and shall take all other action necessary or 
advisable to secure the vote or consent of stockholders required by

its stockholders the obtaining of the Company Stockholder Approval.

registration statement and other document filed by it during such period 
pursuant to the requirements of Federal or state securities laws and (b) all 
other information concerning its business, properties and personnel as such 
other party may reasonably request. Except as required by law, each of the 
Company and Parent will hold, and will cause its respective officers, 
employees, accountants, counsel, financial advisers and other representatives 
and affiliates to hold, any confidential information in accordance with the 
Confidentiality Agreement dated May 10, 1994, between Parent and the Company 
(the "Confidentiality Agreement"). 

SECTION 5.03. Reasonable Efforts; Notification. (a) Upon the terms and 
subject to the conditions set forth in this Agreement, each of the parties 
agrees to use reasonable efforts to take, or cause to be taken, all actions, 
and to do, or cause to be done, and to assist and cooperate with the other 
parties in doing, all things necessary, proper or advisable to consummate and 
make effective, in the most expeditious manner practicable, the Merger and 
the other transactions contemplated by this Agreement, including (i) the 
making of all necessary registrations and filings (including filings with 
Governmental Entities, if any), (ii) the obtaining of all necessary consents, 
approvals or waivers from third parties, and (iii) the execution and delivery 
of any additional instruments necessary to consummate the transactions 
contemplated by, and to fully carry out the purposes of, this Agreement. 

(b) The Company shall give prompt notice to Parent, and Parent shall give 
prompt notice to the Company, of (i) any representation or warranty made by 
it contained in this Agreement that is qualified as to materiality becoming 
untrue or inaccurate in any respect or any such representation or warranty 
that is not so qualified becoming untrue or inaccurate in any material 
respect or (ii) the failure by it to comply with or satisfy in any material 
respect any covenant, condition or agreement to be complied with or satisfied 
by it under this Agreement; provided, however, that no such notification 
shall affect the representations, warranties, covenants, or agreements of the 
parties or the conditions to the obligations of the parties under this 
Agreement. 

SECTION 5.04. Stock Option Plans. (a) As soon as practicable following the 
date of this Agreement, the Board of Directors of the Company (or, if 
appropriate, any committee administering the Stock Options Plans (as defined 
below)) shall adopt such resolutions or take such other actions as are 
required to adjust the terms of all outstanding stock options to purchase 
shares of Company Common Stock ("Stock Options") heretofore granted under 
any, stock option or stock appreciation rights plan, program or arrangement 
of the Company (collectively, the "Stock Option Plans") as is necessary to 
provide that each Stock Option outstanding immediately prior to the Effective 
Time, whether or not then exercisable, shall be immediately converted as of 
the Effective Time into the right to purchase from Parent the Option 
Conversion Number (as defined below) of shares of Parent Common Stock (each 
an "Adjusted Option"). Each Adjusted Option will have substantially the same 
terms as the Stock Option to which it is related, including the same vesting 
schedule (other than (except with respect to Stock Options granted under the 
Company's 1993 Non-Employee Director Stock Option Plan, as to which Section 
5.04(b) applies) to the extent accelerated pursuant to the terms of such 
Stock Option or in accordance with the present terms of any employment 
agreements existing on the date hereof, which Stock Option shall remain 
exercisable following the Effective Time in accordance with the provisions of 
the Stock Option Plan under which granted), except for its exercise price and 
the number and kind of shares subject thereto. The exercise price of any 
Adjusted Option (the "Adjusted Exercise Price") shall be an amount equal to 
the exercise price of the Stock Option related to such Adjusted Option as of 
the date of this Agreement divided by the Exchange Ratio. The "Option 
Conversion Number" for any Adjusted Option shall be equal to the number of 
shares purchasable pursuant to the Stock Option related to such Adjusted 
Option as of the date of this Agreement multiplied by the Exchange Ratio. No 
certificates or scrip representing fractional shares of Parent Common Stock 
shall be issued upon the exercise of any Adjusted Option, and no fractional 
share interest will entitle the owner thereof to vote or to any rights of a 
stockholder of Parent. Each holder of any Adjusted Option who exercises such 
Adjusted Option in accordance with its terms and this Agreement who would 
otherwise have been entitled to receive a fraction of a share of Parent 
Common Stock (after taking into account all Adjusted Options delivered by 
such holder on the date such Adjusted Options are exercised) shall receive, 
in lieu thereof, a whole share of Parent Common Stock if such fraction is 0.5 
or greater, or no additional shares of Parent Common Stock if such fraction 
is less than 0.5. 

(b) Notwithstanding Section 5.04(a), prior to the Closing the Board of 
Directors of the Company (or the relevant committee thereof) shall adopt such 
resolutions and the Company shall obtain such written consents as may be 
necessary to rescind the pending amendment to the 1993 Non-Employee Director 
Stock Option Plan and all Stock Options granted thereunder to provide that 
the vesting of such Stock Options shall not be accelerated as a result of 
this Agreement or the transactions contemplated hereby, but that such Stock 
Options shall instead be converted, as of the Effective Time, into Adjusted 
Options.
<PAGE>
<PAGE>
 
(c) All Stock Option Plans not adjusted pursuant to Section 5.04(a) shall 
terminate as of the Effective Time and the provisions in any other Benefit 
Plan providing for the issuance, transfer or grant of any capital stock of 
the Company or any interest in respect of any capital stock of the Company 
shall be deleted as of the Effective Time, and the Company shall ensure that 
following the Effective Time no holder of a Stock Option or any participant 
in any Stock Option Plan shall have any right thereunder to acquire any 
capital stock of the Company, Parent or the Surviving Corporation, except as 
provided in Section 5.04(a). 

(d) Parent agrees to take such actions as are necessary, for the conversion 
of the Stock Options of the Company pursuant to Section 5.04(a) into Adjusted 
Options, including the reservation, issuance and listing of Parent Common 
Stock, as is necessary to effectuate the transactions contemplated by Section 
5.04(a). 

(e) A holder of an Adjusted Option may exercise such Adjusted Option in whole 
or in part in accordance with its terms by delivering a properly executed 
notice of exercise to Parent, together with the consideration therefor and 
the Federal withholding tax information, if any, required in accordance with 
the related Stock Option Plan. 

SECTION 5.05. Benefit Plans and Employee Matters. (a) Except as provided in 
Section 5.04, Parent currently intends to cause the Surviving Corporation to 
maintain for a period of three years after the Effective Time the Benefit 
Plans of the Company and its subsidiaries in effect on the date of this 
Agreement or to provide benefits to employees of the Company and its 
subsidiaries that are no less favorable in the aggregate to such employees 
than those in effect on the date of this Agreement. 

(b) Parent currently intends, for a period of three years after the Effective 
Time, to provide, or cause its subsidiaries to provide, to persons who are 
employees of the Company or any of its subsidiaries at the Effective Time 
("Company Employees"), and whose employment is thereafter terminated by 
Parent or any of its subsidiaries, with an opportunity to apply for 
subsequent employment opportunities involving substantially similar job 
qualifications with Parent and its subsidiaries prior to the placement of 
advertisements or other open notices to the general public that such 
employment opportunities are available; provided, however, that neither 
Parent nor any of its subsidiaries shall have any obligations to offer 
employment to any such former Company Employees. 

SECTION 5.06. Indemnification, Exculpation and Insurance. (a) The certificate 
of incorporation and the by-laws of the Surviving Corporation shall contain 
the provisions with respect to indemnification and exculpation from liability 
set forth in the Company's certificate of incorporation and by-laws on the 
date of this Agreement, which provisions shall not be amended, repealed or 
otherwise modified for a period of six years from the Effective Time in any 
manner that would adversely affect the rights thereunder of individuals who 
on or prior to the Effective Time were directors, officers, employees or 
agents of the Company, unless such modification is required by law. 

(b) For six years from the Effective Time, Parent shall maintain in effect 
directors' and officers' liability insurance covering those persons who are 
currently covered by the Company's directors' and officers' liability 
insurance policy (a copy of which has been heretofore delivered to Parent) 
(the "Indemnified Parties") on terms no less favorable than the terms of such 
current insurance coverage; provided, however, that in no event shall Parent 
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, Parent shall be obligated to obtain a policy with the 
greatest coverage available for a cost not exceeding such amount. 

(c) In the event Parent, the Surviving Corporation or any of their successors 
or assigns (i) consolidates with or merges into any other person and shall 
not be the continuing or surviving corporation or entity of such 
consolidation or merger or (ii) transfers all or substantially all of its 
properties and assets to any person, then and in each such case, proper 
provisions shall be made so that the successors and assigns of Parent or the 
Surviving Corporation, as the case may be, shall assume the obligations set 
forth in this Section 5.06. 

(d) Parent shall guarantee the obligations of the Surviving Corporation with 
respect to the indemnification provisions contained in the Surviving 
Corporation's certificate of incorporation and by-laws and in the 
indemnification agreements listed in Schedule 5.06 of the Company Disclosure 
Schedule. 

(e) This Section 5.06 shall survive the consummation of the Merger at the 
Effective Time, is intended to benefit the Company, Parent, the Surviving 
Corporation and the Indemnified Parties, and shall be binding on all 
successors and assigns of Parent and the Surviving Corporation. 

SECTION 5.07. Letters of Accountants. (a) The Company shall use its 
reasonable efforts to cause to be delivered to Parent "comfort" letters of 
Deloitte & Touche, the Company's independent public accountants, dated and

(b) Parent shall use its reasonable efforts to cause to be delivered to the 
Company "comfort" letters of Price Waterhouse, Parent's independent public

such press release or make any such public statement prior to such 
consultation, except as may be required by applicable law, court process or

accounting releases with respect to pooling-of-interests accounting treatment 
and (y) prior to the Effective Time, use its reasonable efforts to obtain 
from each such affiliate a written agreement substantially in the form of 
Exhibit 5.10 hereto. The Company shall use its reasonable efforts to obtain 
such a written agreement as soon as practicable from any person who may be 
deemed to have become an affiliate of the Company, after the Company's 
delivery of the letter referred to above and prior to the Effective Time. 

(b) Each party hereto shall use its reasonable efforts to (i) cause the

other actions as are necessary to cure any facts or circumstances that could 
prevent the Merger from qualifying for pooling-of-interests accounting 
treatment. 

(d) Parent shall publish results covering at least 30 days of combined

Parent's fiscal quarter ending immediately following the Effective Time that

requisite majority of the holders of the Senior Notes, by means of a written

                             CONDITIONS PRECEDENT 

SECTION 6.01. Conditions to Each Party's Obligations to Effect the

the Merger, and no temporary restraining order, preliminary or permanent 
injunction or other order issued by any court of competent jurisdiction or 
other legal restraint or prohibition preventing the consummation of the 
Merger shall be in effect. For the purposes of this Agreement a litigation

the Federal Trade Commission shall have publicly announced or shall have 
advised Parent, Sub or the Company that the Federal Trade Commission has 
authorized its staff to commence proceedings in Federal court seeking 
injunctive relief against, or to commence administrative proceedings 
challenging, the transactions contemplated by this Agreement. 

  (d) Form S-4. The Form S-4 shall have been declared effective by the SEC 
under the Securities Act. No stop order suspending the effectiveness of the 
Form S-4 shall have been issued by the SEC, and no proceedings for that

  (e) HSR Act. The applicable waiting period (and any extension thereof)

consents, waivers, orders, approvals, filings, notices or declarations the 
failure to obtain or make which would not have a material adverse effect, at

SECTION 6.02. Additional Conditions to Obligations of Parent and Sub. The 
obligations of Parent and Sub to effect the Merger are also subject to the 
following conditions:
<PAGE>
<PAGE>
 
(a) Representations and Warranties. Each of the representations and 
warranties of the Company contained in this Agreement shall, as of the 
Closing Date as though made on and as of the Closing Date, be true and 
correct except for such failures to be true and correct as could not, 
individually or in the aggregate, reasonably be expected to result in (i) a 
material adverse effect on the Company or on Parent (except that where any 
statement in a representation or warranty expressly includes a standard of 
materiality, such statement shall be true and correct in all respects giving 
effect to such standard) or (ii) an adverse effect on the ability of the 
parties to consummate the transactions contemplated by this Agreement; 
provided that those representations and warranties which address matters only 
as of a particular date shall remain true and correct in all material 
respects (except that where any statement in a representation or warranty 
expressly includes a standard of materiality, such statement shall be true 
and correct in all respects giving effect to such standard) as of such date. 
Parent shall have received a certificate of the Chief Executive Officer and 
Chief Financial Officer of the Company to such effect.

or approval of each person whose consent or approval shall be required in 
connection with the Merger under all loan or credit agreements, notes, 
mortgages, indentures, leases or other agreements or instruments to which it 
or any of its Material Subsidiaries is a party, except those for which 
failure to obtain such consents and approvals would not have a material 
adverse effect on the Company prior to or after the Effective Time or a 
material adverse effect on Parent after the Effective Time. 

  (d) Pooling Letter. Parent shall have received from Price Waterhouse, as 
independent auditors of Parent, on the date of the Proxy Statement and on the 
Closing Date, letters, in each case dated as of such respective dates,

and to the effect that the business combination to be effected by the Merger 
is required to be accounted for as a pooling-of-interests by Parent for 
purposes of its consolidated financial statements under generally accepted 
accounting principles and applicable SEC rules and regulations. No action 
shall have been taken by any Governmental Entity or any statute, rule, 
regulation or order enacted, promulgated or issued by any Governmental 
Entity, or any proposal made for any such action by any Governmental Entity 
which is reasonably likely to be put into effect, that would prevent Parent 
from accounting for the business combination to be effected by the Merger as 
a pooling-of-interests. 

  (e) Affiliate Agreements. Parent shall have received from each person who 
may be deemed to be an affiliate of the Company (under Rule 145 of the

Closing Date a signed agreement substantially in the form of Exhibit 5.10 
hereto.

  (a) Representations and Warranties. Each of the representations and 
warranties of Parent contained in this Agreement shall, as of the Closing 
Date as though made on and as of the Closing Date, be true and correct except 
for such failures to be true and correct as could not, individually or in the 
aggregate, reasonably be expected to result in (i) a material adverse effect 
on Parent (except that where any statement in a representation or warranty 
expressly includes a standard of materiality, such statement shall be true 
and correct in all respects giving effect to such standard) or (ii) an 
adverse effect on the ability of the parties to consummate the transactions 
contemplated by this Agreement; provided that those representations and 
warranties which address matters only as of a particular date shall remain 
true and correct in all material respects (except that where any statement in 
a representation or warranty expressly includes a standard of materiality, 
such statement shall be true and correct in all respects giving effect to 
such standard) as of such date. The Company shall have received a certificate 
of an executive of Parent to such effect. 

  (b) Agreements and Covenants. Parent shall have performed or complied in 
all material respects with the agreements and covenants required by this 
Agreement to be performed or complied with by it on or prior to the Closing 
Date. The Company shall have received a certificate of an executive of Parent 
to that effect. 

  (c) Tax Opinion. The Company shall have received the opinion of Fulbright & 
Jaworski L.L.P., counsel to the Company, dated the date of the Proxy

modified in any material respect. The issuance of such opinion shall be 
conditioned on the receipt of customary representation letters.

  (a) by mutual written consent of Parent and the Company; 

  (b) by Parent, upon a breach of any representation, warranty, covenant or 
agreement on the part of the Company set forth in this Agreement, or if any 
representation or warranty of the Company shall have become untrue, in either 
case such that the conditions set forth in Section 6.02(a) or Section 
6.02(b), as the case may be, would be incapable of being satisfied by 
November 30, 1994; provided that, in any case, a wilful breach shall be 
deemed to cause such conditions to be incapable of being satisfied for 
purposes of this Section 7.01(b); 

  (c) by the Company, upon a breach of any representation, warranty, covenant 
or agreement on the part of Parent set forth in this Agreement, or if any 
representation or warranty of Parent shall have become untrue, in either case 
such that the conditions set forth in Section 6.03(a) or Section 6.03(b), as 
the case may be, would be incapable of being satisfied by November 30, 1994;

  (e) by either Parent or the Company, if the Merger shall not have occurred 
by November 30, 1994, unless the failure to consummate the Merger is the

material breach of any representation or warranty set forth in this Agreement 
by the party seeking to terminate this Agreement; 

  (f) by the Company, if permitted pursuant to Section 2.01(c); or 

  (g) by Parent at any time if the Significant Stockholder loses control of

forth in Section 3.01(t) cease to be true and correct in all respects. 

SECTION 7.02. Effect of Termination. In the event of termination of this 
Agreement by either the Company or Parent as provided in Section 7.01, this 
Agreement shall forthwith become void and have no effect, without any 
liability or obligation on the part of Parent, Sub or the Company, other than 
the provisions of Section 3.01(o), Section 3.02(j), the last sentence of 
Section 5.02, Section 5.08, this Section 7.02 and Article VIII and except to 
the extent that such termination results from the wilful and material breach 
by a party of any of its representations, warranties, covenants or agreements 
set forth in this Agreement. 

SECTION 7.03. Amendment. This Agreement may be amended by the parties at any 
time before or after the Company Stockholder Approval; provided, however, 
that after the Company Stockholder Approval there shall not be made any 
amendment that by law requires further approval by the stockholders of the 
Company without the further approval of such stockholders. This Agreement may 
not be amended except by an instrument in writing signed on behalf of each of 
the parties.

delivered pursuant to this Agreement or (c) subject to the proviso of Section 
7.03, waive compliance with any of the agreements or conditions contained in 
this Agreement. Any agreement on the part of a party to any such extension or 
waiver shall be valid only if set forth in an instrument in writing, signed 
on behalf of such party. The failure of any party to this Agreement to assert 
any of its rights under this Agreement or otherwise shall not constitute a 
waiver of those rights. 

SECTION 7.05. Procedure for Termination, Amendment, Extension or Waiver. A 
termination of this Agreement pursuant to Section 7.01, an amendment of this 
Agreement pursuant to Section 7.03 or an extension or waiver
<PAGE>
<PAGE>

                           FORM OF AFFILIATE LETTER 

Corning Incorporated 
One Riverfront Plaza 
Corning, NY 14831 

Gentlemen: 

I have been advised that as of the date of this letter I may be deemed to be 
an "affiliate" of Nichols Institute, a Delaware corporation (the "Company"), 
as the term "affiliate" is (i) defined within the meaning of Rule 145 of the 
rules and regulations (the "Rules and Regulations") of the Securities and 
Exchange Commission (the "Commission") under the Securities Act of 1933, as 
amended (the "Act"), and/or (ii) used in and for purposes of Accounting 
Series Releases 130 and 135, as amended, of the Commission. Pursuant to the 
terms of the Agreement and Plan of Merger dated as of June 1, 1994 (the 
"Agreement"), among Corning Incorporated, a New York corporation ("Parent"), 
Apple Acquisition Corp., a Delaware corporation ("Sub"), and the Company, Sub 
will be merged with and into the Company (the "Merger"). 

In connection with the Merger, I am entitled to receive shares of common 
stock, par value $.50 per share, of Parent (the "Parent Shares") in exchange 
for shares (or options for shares) owned by me of capital stock of the 
Company (the "Company Shares"). 

I represent, warrant and covenant to Parent that in the event I receive any 
Parent Shares as a result of the Merger: 

(a) I shall not make any sale, transfer or other disposition of the Parent 
Shares in violation of the Act or the Rules and Regulations. 

(b) I have carefully read this letter and the Agreement and discussed the 
requirements of such documents and other applicable limitations upon my 
ability to sell, transfer or otherwise dispose of Parent Shares, to the 
extent I felt necessary, with my counsel or counsel for the Company. 

(c) I have been advised that the issuance of Parent Shares to me pursuant to 
the Merger has been registered with the Commission under the Act on a 
Registration Statement on Form S-4. However, because I have been advised 
that, at the time the Merger is submitted for a vote of the stockholders of 
the Company, (a) I may be deemed to be an affiliate of the Company, and (b) 
other than as set forth in the Agreement, the distribution by me of the 
Parent Shares has not been registered under the Act, I will not sell, 
transfer or otherwise dispose of Parent Shares issued to me in the Merger 
unless (i) such sale, transfer or other disposition is made in conformity 
with the volume and other limitations of Rule 145 promulgated by the 
Commission under the Act, (ii) such sale, transfer or other disposition has 
been made pursuant to an effective registration statement under the Act or 
(iii) in the opinion of counsel reasonably acceptable to Parent or as 
described in a "no-action" or interpretive letter from the Staff of the 
Commission, such sale, transfer or other disposition is otherwise exempt from 
registration under the Act. 

(d) I understand that Parent is under no obligation, other than as set forth 
in the Agreement, to register the sale, transfer or other disposition of the 
Parent Shares by me or on my behalf under the Act or to take any other action 
necessary in order to make compliance with an exemption from such 
registration available solely as a result of the Merger. 

(e) I also understand that there will be placed on the certificates for the 
Parent Shares issued to me, or any substitutions therefor, a legend stating 
in substance: 

THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO 
WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES. THE 
SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE TRANSFERRED IN ACCORDANCE 
WITH THE TERMS OF AN AGREEMENT DATED ------------ ------, 1994 BETWEEN THE 
REGISTERED HOLDER HEREOF AND CORNING INCORPORATED, A COPY OF WHICH AGREEMENT 
IS ON FILE AT THE PRINCIPAL OFFICES OF CORNING INCORPORATED. 

(f) I also understand that unless a sale or transfer is made in conformity 
with the provisions of Rule 145, or pursuant to a registration statement, 
Parent reserves the right to put the following legend on the certificates 
issued to my transferee: 

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE 
SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO RECEIVED SUCH
<PAGE>
<PAGE>
 
SHARES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES 
ACT OF 1933 APPLIES. THE SHARES HAVE BEEN ACQUIRED BY THE HOLDER NOT WITH A 
VIEW TO, OR FOR RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN 
THE MEANING OF THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, PLEDGED OR 
OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH AN EXEMPTION FROM THE 
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933. 

It is understood and agreed that the legends set forth in paragraphs (e) and 
(f) above shall be removed by delivery of substitute certificates without 
such legend if the undersigned shall have delivered to Parent a copy of a 
letter from the staff of the Commission, or an opinion of counsel reasonably 
satisfactory to Parent in form and substance reasonably satisfactory to 
Parent, to the effect that such legend is not required for purposes of the 
Act. 

I further represent to, and covenant with Parent, that I will not, during the 
30 days prior to the Effective Time (as defined in the Agreement), sell, 
transfer or otherwise dispose of the Company Shares or shares of the capital 
stock of Parent that I may hold and, furthermore, that I will not sell, 
transfer or otherwise dispose of Parent Shares received by me in the Merger 
or any other shares of the capital stock of Parent until after such time as 
results covering at least 30 days of combined operations of the Company and 
Parent have been published by Parent, in the form of a quarterly earnings 
report, an effective registration statement filed with the Commission, a 
report to the Commission on Form 10-K, 10-Q, or 8-K, or any other public 
filing or announcement which includes such combined results of operations. 

Execution of this letter should not be considered an admission on my part 
that I am an "affiliate" of the Company as described in the first paragraph 
of this letter, or as a waiver of any rights I may have to object to any 
claim that I am such an affiliate on or after the date of this letter. 

Very truly yours,

EXHIBIT 5.16 

                             EMPLOYMENT AGREEMENT 

AGREEMENT by and between Nichols Institute, a Delaware corporation (the 
"Company"), and Dr. Albert L. Nichols (the "Executive"), dated as of the 
day of     , 1994. 

1. Employment Period; Effectiveness of this Agreement. The Company shall 
employ the Executive, and the Executive shall serve the Company, on the terms 
and conditions set forth in this Agreement, for the period beginning on the 
"Effective Time" of the "Merger", as such terms are defined in the Agreement 
and Plan of Merger by and among Corning, Inc., a New York corporation 
("Corning"), Apple Acquisition Corp. and the Company dated as of June 1, 1994 
(the "Merger Agreement"), and ending on the second anniversary thereof (the 
"Employment Period") provided, however, that the Employment Period may be 
extended for up to an additional three years if mutually agreed by the 
parties prior to such second anniversary (the "Additional Term"). 

2. Waiver of Severance Pay. In consideration for the Company's entering into 
this Agreement, effective upon the commencement of the Employment Period, the 
Executive hereby waives all his rights to severance pay, damages or other 
payments on account of the termination of his employment with the Company or 
as a result of the Merger other than as set forth in this Agreement. 

3. Position and Duties. During the Employment Period, the Executive shall 
serve as Chairman Emeritus of the Company, with duties and responsibilities 
that shall include assisting in the transition resulting from the acquisition 
of the Company by Corning and the coordination and integration of the 
Company's business and operations with those of Corning Life Sciences Inc. 
("CLSI"). The Executive shall be a member of the Board of Directors of CLSI 
with special responsibility for strategic planning. The Executive shall have 
responsibility for helping to integrate the operations of the Company with 
those of CLSI; assisting the Chief Executive Officer of CLSI in developing 
long-term strategic planning for the Company and CLSI; at the request of the 
Chief Executive Officer of CLSI, meeting with and visiting customers of both 
the Company and CLSI in seeking to maintain and extend the business 
operations of both the Company and CLSI; reviewing with the Chief Executive 
Officer of CLSI new scientific strategies for both the Company and CLSI; and 
such other duties and responsibilities, consistent with his status as 
Chairman Emeritus of the Company, as may be accepted by him. The Executive 
shall have direct reporting responsibilities only to the Chief Executive 
Officer of CLSI (who shall be the Chairman of the Company). The Executive's 
services shall be performed primarily during normal business hours, may be 
performed primarily in California and are not expected to be full time. The 
Executive may engage in other business activities, in particular maintaining 
his license as a doctor of medicine, so long as they do not interfere with 
the performance of his duties under this Agreement and do not violate Section 
7 of this Agreement. 

4. Compensation. (a) Base Salary. During the Employment Period, the Executive 
shall receive a salary (the "Salary") of $250,000 per annum, payable in 
monthly installments. 

(b) Incentive Compensation. (i) Whether or not the Employment Period shall 
have ended, for each of the five years following the Merger, the Executive 
shall receive a guaranteed lump sum bonus of $500,000, payable in arrears; 
and (ii) at the end of the Employment Period, the Executive shall be eligible 
for an incentive bonus of between $1,000,000 and $2,000,000, based upon 
achievement of certain performance criteria to be mutually agreed upon in 
writing by the Executive and Chief Executive Officer of CLSI, prior to the 
Effective Time. In the event the Executive is employed for the Additional 
Term, he shall be eligible for similar incentive bonus compensation at the 
end of such term. 

(c) Other Benefits. During the Employment Period, the Executive shall be 
entitled to participate in all welfare benefit and tax-qualified savings and 
retirement plans of the Company and the CLSI group companies to the same 
extent as peer executives. The Executive shall not be entitled to participate 
in any bonus, incentive, severance or nonqualified profit-sharing or deferred 
compensation plans, programs or policies of the Company and its affiliated 
companies, except as specifically provided herein. 

(d) Vacation; Support Services; Expenses. During the Employment Period and, 
if applicable, the Additional Term, the Executive shall be entitled to: (i) 
eight weeks' vacation per year; (ii) an office, secretarial services, and 
other support services necessary to the performance of his duties under this 
Agreement; (iii) maintain the use of his current Company car; and (iv) 
reimbursement of business expenses in accordance with Company policies. 

5. Termination of Employment. (a) Death or Disability. The Executive's 
employment shall terminate automatically upon the Executive's death during 
the Employment Period. The Company shall be entitled to terminate the 
Executive's employment because of the Executive's Disability during the 
Employment Period. "Dis
<PAGE>
<PAGE>
 
ability" means that (i) the Executive has been unable, for a period of 180 
consecutive business days, to perform his duties under this Agreement, as a 
result of physical or mental illness or injury, and (ii) a physician selected 
by the Company or its insurers, and acceptable to the Executive or the 
Executive's legal representative, has determined that the Executive's 
incapacity is total and permanent. A termination of the Executive's 
employment by the Company for Disability shall be communicated to the 
Executive by written notice, and shall be effective on the 30th day after 
receipt of such notice by the Executive (the "Disability Effective Date"), 
unless the Executive returns to full-time performance of the Executive's 
duties before the Disability Effective Date. 

(b) Cause. The Company may terminate the Executive's employment during the 
Employment Period for Cause or without Cause by giving him written notice of 
its intention to do so. "Cause" means repeated and gross negligence in 
fulfillment of, or repeated failure of the Executive to fulfill his material 
obligations under this Agreement, in either event after due written notice 
thereof, or serious willful misconduct by the Executive in respect of his 
obligations hereunder. Cause should not include, without limitation, (a) 
refusal by the Executive of an assignment not consistent with the status, 
titles and reporting requirements set forth herein or contemplated hereby, or 
(b) bad judgment or negligence of the Executive, or (c) any act or omission 
(other than one constituting a material breach of trust committed in willful 
or reckless disregard of the interest of the Company, CLSI or Corning and 
undertaken for personal gain) in respect of which a determination could 
properly have made by the Board of Directors of the Company that the 
Executive met the applicable standard of conduct prescribed for 
indemnification or reimbursement under the by-laws of the Company or the laws 
of Delaware, in each case in effect at the time of such act or omission, or 
(d) any act or omission which would otherwise constitute Cause with respect 
to which notice of termination is given more than twelve (12) months after 
the earliest date on which any senior executive officer of Corning who was 
not a party to such act or omission knew or should have known of such act or 
omission. 

6. Obligations of the Company upon Termination.  (a) Other than for Cause, 
Death or Disability. If, during the Employment Period, the Company terminates 
the Executive's employment other than for Cause or Disability, the Company 
shall continue to provide the compensation and benefits provided for in 
Section 4 as if the Executive had remained employed under this Agreement 
through the end of the Employment Period or, if applicable, the Additional 
Term, provided that the Executive's entitlement to payments pursuant to 
Section 4(b)(ii) in the event of such termination will be determined pursuant 
to criteria to be mutually agreed upon by the Executive and the Chief 
Executive Officer of CLSI prior to the Effective Time, in the case of a 
termination during the Employment Period, and prior to the end of the 
Employment Period, in the case of a termination during the Additional Term. 
To the extent that the Executive may not, under the terms of any applicable 
law, regulation, plan document or contract, be treated as still employed by 
the Company for purposes of any benefits provided for in paragraph (c) of 
Section 4, the Company shall provide the Executive with substantially 
equivalent benefits in such manner as it deems appropriate. Notwithstanding 
the foregoing, during any period when the Executive is eligible to receive 
any benefits from another employer, the benefits provided by the Company 
under this subparagraph may be made secondary to those provided by such other 
employer. The payments provided pursuant to this paragraph (a) of Section 6 
are intended as liquidated damages for a termination of the Executive's 
employment by the Company other than for Cause or Disability, and shall be 
the sole and exclusive remedy therefor. 

(b) Cause; By Executive. If the Executive's employment is terminated during 
the Employment Period (or, if applicable, the Additional Term) by the Company 
for Cause or by the Executive for any reason other than as a result of a 
breach by the Company of this Agreement, the Company shall pay the accrued 
but unpaid Salary through the Date of Termination to the Executive or the 
Executive's estate or legal representative, as applicable, and shall make the 
payments provided in Section 4(b)(i), and the Company shall have no further 
obligations under this Agreement. 

(c) Death or Disability. If the Executive's employment is terminated during 
the Employment Period because of the Executive's death or Disability, (i) the 
Company shall continue to pay the Salary to the Executive or the Executive's 
estate or legal representative, as applicable, through the end of the 
Employment Period, or, if applicable, the Additional Term, (ii) the Company 
shall make the payments described in Section 4(b)(i), and (iii) the Company 
shall have no further obligations under this Agreement. 

7. Non-Competition; Confidential Information. (a) For a period of five years 
from the commencement of the Employment Period (the "Restricted Period") the 
Executive shall not, without the prior written consent of CLSI, engage in or 
become associated (directly or indirectly), as an owner, employee, officer, 
director, independent contractor, agent, partner, advisor, or in any other 
capacity calling for the rendition of his personal services, with any 
individual, partnership, corporation or other organization or entity that is 
engaged in the business of clinical laboratory testing (including diagnostic 
testing) in the United States; provided that the foregoing shall not prevent 
the Executive from making and holding investments of up to five percent of 
the equity of an entity engaged in such business, if such equity is listed on 
a national securities exchange or regularly traded in the over-the-counter 
market.
<PAGE>
<PAGE>
 
The Executive further agrees that during the Restricted Period, the Executive 
shall not, without the prior written consent of CLSI, solicit, assist or 
encourage the solicitation of, any employee of the Company or any of its 
affiliates to leave the employ of the Company or such affiliate. 

(b) During the Employment Period and at all times thereafter, the Executive 
shall not disclose to anyone who is not employed by the Company or by an 
affiliate or to any employee of the Company or an affiliate who, to the 
knowledge of the Executive, is not authorized to receive such information, 
any confidential information of the Company and any confidential information 
relating to the Company's former or present customers or potential customers 
of which the Executive becomes aware during the Employment Period. The 
Executive shall hold in a fiduciary capacity for the benefit of the Company 
all secret or confidential information, knowledge or data relating to the 
Company or any of its affiliated companies and their respective businesses 
that the Executive obtains during the Executive's employment by the Company 
or any of its affiliated companies and that is not public knowledge (other 
than as a result of the Executive's violation of this Section 7) 
("Confidential Information"). The Executive shall not communicate, divulge or 
disseminate Confidential Information at any time during or after the 
Executive's employment with the Company, except with the prior written 
consent of the Company or as otherwise required by law or legal process. 

(c) This Section 7 shall survive the expiration of the Employment Period and 
any termination of the Executive's employment throughout the Restricted 
Period, notwithstanding any other provision of this Agreement. 

8. Legal Fees and Expenses. The Company shall reimburse the Executive for all 
legal fees and expenses that the Executive may reasonably incur as a result 
of any contest by the Company, the Executive or others of the validity or 
enforceability of, or liability under, any provision of this Agreement, if 
the Executive is the prevailing party in such contest. 

9. Successors. (a) This Agreement is personal to the Executive and, without 
the prior written consent of the Company, shall not be assignable by the 
Executive otherwise than by will or the laws of descent and distribution. 
This Agreement shall inure to the benefit of and be enforceable by the 
Executive's legal representatives. 

(b) This Agreement shall inure to the benefit of and be binding upon the 
Company and its successors and assigns. 

(c) The Company shall require any successor (whether direct or indirect, by 
purchase, merger, consolidation or otherwise) to all or substantially all of 
the business and/or assets of the Company expressly to assume and agree to 
perform this Agreement in the same manner and to the same extent that the 
Company would have been required to perform it if no such succession had 
taken place. As used in this Agreement, "Company" shall mean both the Company 
as defined above and any such successor that assumes and agrees to perform 
this Agreement, by operation of law or otherwise. 

10. Miscellaneous. (a) This Agreement shall be governed by, and construed in 
accordance with, the laws of the State of New York, without reference to 
principles of conflict of laws. The captions of this Agreement are not part 
of the provisions hereof and shall have no force or effect. This Agreement 
may not be amended or modified except by a written agreement executed by the 
parties hereto or their respective successors and legal representatives. 

(b) All notices and other communications under this Agreement shall be in 
writing and shall be given by hand delivery to the other party or by

Corning Incorporated 
One Riverfront Plaza 
Corning, New York 14831 
Dear Sirs: 

The undersigned understands that Corning Incorporated ("Parent"), Apple 
Acquisition Corp. ("Merger Sub") and Nichols Institute (the "Company") are 
entering into an Agreement and Plan of Merger (the "Agreement") pursuant to 
which Merger Sub will be merged with and into the Company (the "Merger") and 
whereby each share of Class A Common Stock, par value $.10 per share ("Class 
A Common"), Class B Common Stock, par value $.10 per share ("Class B 
Common"), and Class C Common Stock, par value $.10 per share ("Class C 
Common"), of the Company (collectively, the "Company Common Stock") issued 
and outstanding immediately as of the effective date of the Merger (including 
shares of Company Common Stock issuable upon the automatic conversion of the 
Company's Series E Convertible Preferred Stock, par value $.10 per share 
("Company Preferred Stock") in accordance with terms thereof as of the 
effective time of the Merger) will be converted into the right to receive 
shares of Common Stock, par value $.50 per share, of Parent ("Parent Common 
Stock"). 

The undersigned is a stockholder of the Company (the "Stockholder") and is 
entering into this letter agreement to induce you to enter into the Agreement 
and to consummate the transactions contemplated thereby. 

The Stockholder confirms his agreement with Parent as follows: 

1. The Stockholder represents, warrants and agrees that (subject only to the 
community property rights of Patricia Wright Nichols, who consents to this 
letter agreement and the arrangements contemplated hereby) he is the record 
or beneficial owner of 3,818 shares of Class A Common (all of which he holds 
a trustee, with sole voting power, of a trust), 1,334,423 shares of Class B 
Common (42,470 of which he holds a trustee with sole voting power, of a 
trust), 1,047,629 shares of Class C Common (45,842 all of which he holds a 
trustee, with sole voting power, of a trust) and no shares of Company 
Preferred Stock (collectively, the "Shares"), and stock options to purchase 
5,000 shares of Class A Common and 155,944 shares of Class C Common, all free 
and clear of all liens, charges, encumbrances, voting agreements and 
commitments of every kind except as has been disclosed previously to Parent 
in writing. The Stockholder does not own or hold any rights to acquire any 
additional shares of the capital stock of Parent (by exercise of stock 
options or otherwise) or any interest therein or any voting rights with 
respect to any additional shares. 

2. The Stockholder agrees that, from the date hereof until the Agreement is 
terminated in accordance with its terms, he will not, and will not permit any 
entity controlled by the Stockholder to, (i) convert any of the shares of 
Class B Common included within the Shares into Class A Common, (ii) contract 
to sell, sell or otherwise transfer or dispose of any of the Shares or any 
interest therein or securities convertible thereinto or any voting rights 
with respect thereto, other than (x) pursuant to the Merger, (y) with 
Parent's prior written consent or (z) the use of Shares as collateral 
pursuant to any existing loan arrangement disclosed previously to Parent in 
writing to secure indebtedness in an amount not to exceed $2,200,000, (iii) 
consent to any amendment to the certificate of incorporation of the Company 
which would effectively reduce the proportionate voting power of the Shares 
or (iv) to the extent any Shares are subject to any encumbrances disclosed in 
writing to Parent, increase the amount of indebtedness secured by such Shares 
to more than $2,200,000. The Stockholder shall inform Parent prior to any 
material increase in his indebtedness under the aforementioned loan 
arrangements. 

3. The Stockholder agrees that, from the date hereof until the Agreement is 
terminated in accordance with its terms, all of the Company Common Stock and 
Company Preferred Stock (including the Shares) beneficially owned by the 
Stockholder, or over which the Stockholder has voting power or control, 
directly or indirectly, in each case at the record date for any meeting of 
stockholders of the Company called to consider and vote, or for any 
solicitation of consents, to approve the Agreement and/or the transactions 
contemplated thereby will be voted by the Stockholder in favor thereof and 
that such shares will not be voted in favor of any other Takeover Proposal 
(as such term is defined in the Agreement) during such period.
<PAGE>
<PAGE>
 
4.  The Stockholder agrees to cooperate fully with Parent in connection with 
the Agreement and the transactions contemplated thereby. The Stockholder 
agrees that he will not, and will not instruct his agents, employees or 
representatives or the officers, employees, agents or representatives of the 
Company to, directly or indirectly, (i) solicit or initiate, or encourage the 
submission of, any Takeover Proposal or (ii) participate in any discussions 
or negotiations regarding, or furnish to any person any information with 
respect to, or take any other action to facilitate any inquiries or the 
making of any proposal that constitutes, or may reasonably be expected to 
lead to, any Takeover Proposal. 

This letter agreement may be terminated at the option of any party at any 
time after termination of the Agreement in accordance with its terms. The 
provisions of Sections 8.07 and 8.09 of the Agreement shall apply to this 
letter agreement (as though all references to "this Agreement" in said 
Sections referred to this letter agreement). 

Please confirm that the foregoing correctly states the understanding between 
us by signing and returning to us a counterpart hereof. 

Very truly yours, 
/s/ Albert L. Nichols, M.D.

Board of Directors 
Nichols Institute 
33608 Ortega Highway 
San Juan Capistrano, California 92690 

Dear Sirs: 

You have asked us to advise you with respect to the fairness to the 
stockholders of Nichols Institute (the "Company") from a financial point of 
view of the consideration to be exchanged by Corning Incorporated ("Corning") 
pursuant to the terms of the Agreement and Plan of Merger, dated as of June 
1, 1994 (the "Merger Agreement"), between the Company and Corning. The Merger 
Agreement provides for the merger (the "Merger") of a wholly owned subsidiary 
of Corning with and into the Company pursuant to which each outstanding share 
of the Company's Class A, Class B, and Class C Common Stock, par value $0.10 
per share (other than shares of Class B Common Stock as to which appraisal 
rights have been perfected), will be converted into the right to receive not 
more than 0.491 shares of Corning Common Stock depending on the average 
Corning share price for the ten trading days ending on the fifth trading day 
prior to the meeting of the Company's stockholders to approve the Merger. 
Each share of the Company's Series E Convertible Preferred Stock (other than 
shares of such Preferred Stock as to which appraisal rights have been 
perfected) will be converted into Corning Common Stock in the manner and the 
amount provided for pursuant to the terms of such Preferred Stock. In 
arriving at our opinion, we have reviewed certain publicly available business 
and financial information relating to the Company and Corning. We have also 
reviewed certain other information, including financial forecasts, provided 
to us by the Company and Corning, and have met with the Company's and 
Corning's management to discuss the business and prospects of the Company and 
Corning. 

We have also considered certain financial and stock market data of the 
Company and Corning, and we have compared that data with similar data for 
other publicly held companies in businesses similar to those of the Company 
and we have considered the financial terms of certain other business 
combinations which have recently been effected. We also considered such other 
information, financial studies, analyses and investigations and financial, 
economic and market criteria which we deemed relevant, and have discussed 
with representatives of the Company and of Peter J. Solomon Securities 
Company Limited ("Solomon") information developed by Solomon regarding other 
potential opportunities for the sale of the Company. However, we were not 
involved in any discussions which representatives of the Company or Solomon 
have had with any third parties in this regard. 

In connection with our review, we have not independently verified any of the 
foregoing information and have relied on its being complete and accurate in 
all material respects. With respect to the financial forecasts, we have 
assumed that they have been reasonably prepared on bases reflecting the best 
currently available estimates and judgments of the Company's and Corning's 
management as to the future financial performance of the Company and Corning, 
respectively. In addition, we have not made an independent evaluation or 
appraisal of the assets of the Company or Corning, nor have we been furnished 
with any such appraisals. 

We have acted as a financial advisor to the Company's Board of Directors in 
connection with the Merger and will receive a fee for rendering this opinion, 
payable in part upon delivering the opinion and in part upon consummation of 
the Merger. 

In the ordinary course of our business, we may trade the debt and equity 
securities of both the Company and Corning for our own account and for the 
accounts of customers and, accordingly, may at any time hold a long or short 
position in such securities. Further, John M. Hennessy, Chairman of the 
Executive Board and Chief Executive Officer of CS First Boston, Inc., is a 
member of Corning's Board of Directors.

It is understood that this letter is for the information of the Board of 
Directors of the Company only and may be published in its entirety in the 
prospectus/proxy statement to be distributed to stockholders of the Company 
and to be included in Corning's Form S-4 Registration Statement to be filed 
in connection with the Merger so long as we give our prior written consent to 
any summary of, excerpt from or reference to such opinion which consent shall 
not be unreasonably withheld. This letter is not to be quoted or referred to, 
in whole or in part, in any other proxy statement or in any other 
registration statement or prospectus, or in any other document used in 
connection with the offering or sale of securities, nor shall this letter be 
used for any other purposes, without CS First Boston's prior written consent. 

Based upon and subject to the foregoing, it is our opinion that, as of the 
date hereof, the consideration to be paid by Corning pursuant to the Merger 
Agreement is fair to each class of the Company's stockholders from a 
financial point of view. 

Sincerely,

APPENDIX D 

               GENERAL CORPORATION LAW OF THE STATE OF DELAWARE 

S. 262. Appraisal Rights. 
(a) Any stockholder of a corporation of this State who holds shares of stock 
on the date of the making of a demand pursuant to subsection (d) of this 
section with respect to such shares, who continuously holds such shares 
through the effective date of the merger or consolidation, who has otherwise 
complied with subsection (d) of this section and who has neither voted in 
favor of the merger or consolidation nor consented thereto in writing 
pursuant to S. 228 of this title shall be entitled to an appraisal by the 
Court of Chancery of the fair value of his shares of stock under the 
circumstances described in subsections (b) and (c) of this section. As used 
in this section, the word "stockholder" means a holder of record of stock in 
a stock corporation and also a member of record of a nonstock corporation; 
the words "stock" and "share" mean and include what is ordinarily meant by 
those words and also membership or membership interest of a member of a 
nonstock corporation. 

(b) Appraisal rights shall be available for the shares of any class or series 
of stock of a constituent corporation in a merger or consolidation to be 
effected pursuant to S. 251, 252, 254, 257, 258 or 264 of this title: 

  (1) Provided, however, that no appraisal rights under this section shall be 
available for the shares of any class or series of stock which, at the record 
date fixed to determine the stockholders entitled to receive notice of and to 
vote at the meeting of stockholders to act upon the agreement of merger or 
consolidation, were either (i) listed on a national securities exchange or 
designated as a national market system security on an interdealer quotation 
system by the National Association of Securities Dealers, Inc. or (ii) held 
of record by more than 2,000 stockholders; and further provided that no 
appraisal rights shall be available for any shares of stock of the 
constituent corporation surviving a merger if the merger did not require for 
its approval the vote of the stockholders of the surviving corporation as 
provided in subsection (f) of S. 251 of this title. 

  (2) Notwithstanding paragraph (1) of this subsection, appraisal rights 
under this section shall be available for the shares of any class or series 
of stock of a constituent corporation if the holders thereof are required by 
the terms of an agreement of merger or consolidation pursuant to S.S. 251, 
252, 254, 257, 258 and 264 of this title to accept for such stock anything 
except: 

    a. Shares of stock of the corporation surviving or resulting from such 
merger or consolidation; 

    b. Shares of stock of any other corporation which at the effective date 
of the merger or consolidation will be either listed on a national securities 
exchange or designated as a national market system security on an interdealer 
quotation system by the National Association of Securities Dealers, Inc. or 
held of record by more than 2,000 stockholders; 

    c. Cash in lieu of fractional shares of the corporations described in the 
foregoing subparagraphs a. and b. of this paragraph; or 

    d. Any combination of the shares of stock and cash in lieu of fractional 
shares described in the foregoing subparagraphs a., b. and c. of this 
paragraph. 

  (3) In the event all of the stock of a subsidiary Delaware corporation 
party to a merger effected under S. 253 of this title is not owned by the 
parent corporation immediately prior to the merger, appraisal rights shall be 
available for the shares of the subsidiary Delaware corporation. 

(c) Any corporation may provide in its certificate of incorporation that 
appraisal rights under this section shall be available for the shares of any 
class or series of its stock as a result of an amendment to its certificate 
of incorporation, any merger or consolidation in which the corporation is a 
constituent corporation or the sale of all or substantially all of the assets 
of the corporation. If the certificate of incorporation contains such a 
provision, the procedures of this section, including those set forth in 
subsections (d) and (e) of this section, shall apply as nearly as is 
practicable. 

(d) Appraisal rights shall be perfected as follows: 

  (1) If a proposed merger or consolidation for which appraisal rights are 
provided under this section is to be submitted for approval at a meeting of 
stockholders, the corporation, not less than 20 days prior to the meeting, 
shall notify each of its stockholders who was such on the record date for 
such meeting with respect to shares for which appraisal rights are available 
pursuant to subsections (b) or (c) hereof that appraisal rights are available 
for any or all of the shares of the constituent corporations, and shall 
include in such notice a copy of this section. Each stockholder electing to 
demand the appraisal of his shares shall deliver to the cor
<PAGE>
<PAGE>
 
poration, before the taking of the vote on the merger or consolidation, a 
written demand for appraisal of his shares. Such demand will be sufficient if 
it reasonably informs the corporation of the identity of the stockholder and 
that the stockholder intends thereby to demand the appraisal of his shares. A 
proxy or vote against the merger or consolidation shall not constitute such a 
demand. A stockholder electing to take such action must do so by a separate 
written demand as herein provided. Within 10 days after the effective date of 
such merger or consolidation, the surviving or resulting corporation shall 
notify each stockholder of each constituent corporation who has complied with 
this subsection and has not voted in favor of or consented to the merger or 
consolidation of the date that the merger or consolidation has become 
effective; or 

  (2) If the merger or consolidation was approved pursuant to S. 228 or 253 
of this title, the surviving or resulting corporation, either before the 
effective date of the merger or consolidation or within 10 days thereafter, 
shall notify each of the stockholders entitled to appraisal rights of the 
effective date of the merger or consolidation and that appraisal rights are 
available for any or all of the shares of the constituent corporation, and 
shall include in such notice a copy of this section. The notice shall be sent 
by certified or registered mail, return receipt requested, addressed to the 
stockholder at his address as it appears on the records of the corporation. 
Any stockholder entitled to appraisal rights may, within 20 days after the 
date of mailing of the notice, demand in writing from the surviving or 
resulting corporation the appraisal of his shares. Such demand will be 
sufficient if it reasonably informs the corporation of the identity of the 
stockholder and that the stockholder intends thereby to demand the appraisal 
of his shares. 

(e) Within 120 days after the effective date of the merger or consolidation, 
the surviving or resulting corporation or any stockholder who has complied 
with subsections (a) and (d) hereof and who is otherwise entitled to 
appraisal rights, may file a petition in the Court of Chancery demanding a 
determination of the value of the stock of all such stockholders. 
Notwithstanding the foregoing, at any time within 60 days after the effective 
date of the merger or consolidation, any stockholder shall have the right to 
withdraw his demand for appraisal and to accept the terms offered upon the 
merger or consolidation. Within 120 days after the effective date of the 
merger or consolidation, any stockholder who has complied with the 
requirements of subsections (a) and (d) hereof, upon written request, shall 
be entitled to receive from the corporation surviving the merger or resulting 
from the consolidation a statement setting forth the aggregate number of 
shares not voted in favor of the merger or consolidation and with respect to 
which demands for appraisal have been received and the aggregate number of 
holders of such shares. Such written statement shall be mailed to the 
stockholder within 10 days after his written request for such a statement is 
received by the surviving or resulting corporation or within 10 days after 
expiration of the period for delivery of demands for appraisal under 
subsection (d) hereof, whichever is later. 

(f) Upon the filing of any such petition by a stockholder, service of a copy 
thereof shall be made upon the surviving or resulting corporation, which 
shall within 20 days after such service file in the office of the Register in 
Chancery in which the petition was filed a duly verified list containing the 
names and addresses of all stockholders who have demanded payment for their 
shares and with whom agreements as to the value of their shares have not been 
reached by the surviving or resulting corporation. If the petition shall be 
filed by the surviving or resulting corporation, the petition shall be 
accompanied by such a duly verified list. The Register in Chancery, if so 
ordered by the Court, shall give notice of the time and place fixed for the 
hearing of such petition by registered or certified mail to the surviving or 
resulting corporation and to the stockholders shown on the list at the 
addresses therein stated. Such notice shall also be given by 1 or more 
publications at least 1 week before the day of the hearing, in a newspaper of 
general circulation published in the City of Wilmington, Delaware or such 
publication as the Court deems advisable. The forms of the notices by mail 
and by publication shall be approved by the Court, and the costs thereof 
shall be borne by the surviving or resulting corporation. 

(g) At the hearing on such petition, the Court shall determine the 
stockholders who have complied with this section and who have become entitled 
to appraisal rights. The Court may require the stockholders who have demanded 
an appraisal for their shares and who hold stock represented by certificates 
to submit their certificates of stock to the Register in Chancery for 
notation thereon of the pendency of the appraisal proceedings; and if any 
stockholder fails to comply with such direction, the Court may dismiss the 
proceedings as to such stockholder. 

(h) After determining the stockholders entitled to an appraisal, the Court 
shall appraise the shares, determining their fair value exclusive of any 
element of value arising from the accomplishment or expectation of the merger 
or consolidation, together with a fair rate of interest, if any to be paid 
upon the amount determined to be the fair value. In determining such fair 
value, the Court shall take into account all relevant factors. In determining 
the fair rate of interest, the Court may consider all relevant factors, 
including the rate of interest which the surviving or resulting corporation 
would have had to pay to borrow money during the pendency of the proceeding. 
Upon application by the surviving or resulting corporation or by any 
stockholder entitled to participate in the appraisal proceeding, the Court 
may, in its discretion, permit discovery or other pretrial proceedings and 
may proceed to trial
<PAGE>
<PAGE>
 
upon the appraisal prior to the final determination of the stockholder 
entitled to an appraisal. Any stockholder whose name appears on the list 
filed by the surviving or resulting corporation pursuant to subsection (f) of 
this section and who has submitted his certificates of stock to the Register 
in Chancery, if such is required, may participate fully in all proceedings 
until it is finally determined that he is not entitled to appraisal rights 
under this section. 

(i) The Court shall direct the payment of the fair value of the shares, 
together with interest, if any, by the surviving or resulting corporation to 
the stockholders entitled thereto. Interest may be simple or compound, as the 
Court may direct. Payment shall be so made to each such stockholder, in the 
case of holders of uncertificated stock forthwith, and the case of holders of 
shares represented by certificates upon the surrender to the corporation of 
the certificates representing such stock. The Court's decree may be enforced 
as other decrees in the Court of Chancery may be enforced, whether such 
surviving or resulting corporation be a corporation of this State or of any 
state. 

(j) The costs of the proceeding may be determined by the Court and taxed upon 
the parties as the Court deems equitable in the circumstances. Upon 
application of a stockholder, the Court may order all or a portion of the 
expenses incurred by any stockholder in connection with the appraisal 
proceeding, including, without limitation, reasonable attorney's fees and the 
fees and expenses of experts, to be charged pro rata against the value of all 
the shares entitled to an appraisal. 

(k) From and after the effective date of the merger or consolidation, no 
stockholder who has demanded his appraisal rights as provided in subsection 
(d) of this section shall be entitled to vote such stock for any purpose or 
to receive payment of dividends or other distributions on the stock (except 
dividends or other distributions payable to stockholders of record at a date 
which is prior to the effective date of the merger or consolidation); 
provided, however, that if no petition for an appraisal shall be filed within 
the time provided in subsection (e) of this section, or if such stockholder 
shall deliver to the surviving or resulting corporation a written withdrawal 
of his demand for an appraisal and an acceptance of the merger or 
consolidation, either within 60 days after the effective date of the merger 
or consolidation as provided in subsection (e) of this section or thereafter 
with the written approval of the corporation, then the right of such 
stockholder to an appraisal shall cease. Notwithstanding the foregoing, no 
appraisal proceeding in the Court of Chancery shall be dismissed as to any 
stockholder without the approval of the Court, and such approval may be 
conditioned upon such terms as the Court deems just. 

(l) The shares of the surviving or resulting corporation to which the shares 
of such objecting stockholders would have been converted had they assented to 
the merger or consolidation shall have the status of authorized and unissued 
shares of the surviving or resulting corporation.

PART II 
                    INFORMATION NOT REQUIRED IN PROSPECTUS 

Item 20. Indemnification of Directors and Officers. 
Under the NYBCL, a corporation may indemnify its directors and officers made, 
or threatened to be made, a party to any action or proceeding, except for 
stockholder derivative suits, if such director or officer acted in good 
faith, for a purpose which he or she reasonably believed to be in or, in the 
case of service to another corporation or enterprise, not opposed to, the 
best interests of the corporation, and, in criminal proceedings, had no 
reasonable cause to believe his or her conduct was unlawful. In the case of 
stockholder derivative suits, the corporation may indemnify a director or 
officer if he or she acted in good faith for a purpose which he or she 
reasonably believed to be in or, in the case of service to another 
corporation or enterprise, not opposed to the best interests of the 
corporation, except that no indemnification may be made in respect of (i) a 
threatened action, or a pending action which is settled or otherwise disposed 
of, or (ii) any claim, issue or matter as to which such person has been 
adjudged to be liable to the corporation, unless and only to the extent that 
the court in which the action was brought, or, if no action was brought, any 
court of competent jurisdiction, determines upon application that, in view of 
all the circumstances of the case, the person is fairly and reasonably 
entitled to indemnity for such portion of the settlement amount and expenses 
as the court deems proper. 

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

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

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

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

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

Item 22. Undertakings. 
The undersigned registrant hereby undertakes: 

  (1) That, for purposes of determining any liability under the Securities 
Act, each fling of the registrant's annual report pursuant to Section 13(a) 
or Section 15(d) of the Securities Exchange Act of 1934 (and, where 
applicable, each filing of an employee benefit plan's annual report pursuant 
to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated 
by reference in the registration statement shall be deemed to be a new 
registration statement relating to the securities offered therein, and the 
offering of such securities at that time shall be deemed to be the initial 
bona fide offering thereof. 

  (2) That prior to any public reoffering of the securities registered 
hereunder through use of a prospectus which is a part of this registration 
statement, by any person or party who is deemed to be an underwriter within 
the meaning of Rule 145(c), the issuer undertakes that such reoffering 
prospectus will contain the information called for by the applicable 
registration form with respect to reofferings by persons who may be deemed 
underwriters, in addition to the information called for by the other items of 
the applicable form. 
(3) That every prospectus (i) that is filed pursuant to paragraph (2) 
immediately preceding, or (ii) that purports to meet the requirements of 
Section 10(a)(3) of the Securities Act and is used in connection with an 
offering of securities subject to Rule 415, will be filed as a part of an 
amendment to the registration statement and will not be used until such 
amendment is effective, and that, for purposes of determining any liability 
under the Securities Act, each such post-effective amendment shall be deemed 
to be a new registration statement relating to the securities offered 
therein, and the offering of such securities at that time shall be deemed to 
be the initial bona fide offering thereof. 

  (4) To respond to requests for information that is incorporated by 
reference into the prospectus pursuant to item 4, 10(b), 11, or 13 of this 
form, within one business day of receipt of such request, and to send the 
incorporated documents by first class mail or other equally prompt means. 
This includes information contained in documents filed subsequent to the 
effective date of the registration statement through the date of responding 
to the request. 

  (5) To supply by means of a post-effective amendment all information 
concerning a transaction, and the company being acquired involved therein, 
that was not the subject of and included in the registration statement when 
it became effective. 

Insofar as indemnification for liabilities arising under the Securities Act 
may be permitted to directors, officers and controlling persons of the 
registrant pursuant to the provisions of Item 20 hereof, or otherwise, the 
registrant has been advised that in the opinion of the Securities and 
Exchange Commission such indemnification is against public policy as 
expressed in the Securities Act and is, therefore, unenforceable. In the 
event that a claim for indemnification against such liabilities (other than 
the payment by the registrant of expenses incurred or paid by a director, 
officer or controlling person of the registrant in the successful defense of 
any action, suit, or proceeding) is asserted by such director, officer or 
controlling person in connection with the securities being registered, the 
registrant will, unless in the opinion of its counsel the matter has been 
settled by controlling precedent, submit to a court of appropriate 
jurisdiction the question whether such indemnification by it is against 
public policy as expressed in the Securities Act and will be governed by the 
final adjudication of such issue. 
SIGNATURES 

Pursuant to the requirements of the Securities Act, the registrant has duly 
caused this registration statement to be signed on its behalf by the 
undersigned, thereunto duly authorized, in The City of Corning, State of New 
York, on July 28, 1994.

For a description of the Company's bank financing arrangements, see Note 2 in 
the accompanying consolidated financial statements. 

Average borrowings were determined based on the daily amounts outstanding. 
The weighted average interest rate during the period was computed by dividing 
actual interest expense in each period by average short-term borrowings in 
such period. The Company had no borrowings outstanding under its principal 
line of credit since April 1993 (see Note 2 in the accompanying consolidated 
financial statements).

CERTIFICATE OF AMENDMENT 
OF 
THE CERTIFICATE OF INCORPORATION 
OF CORNING INCORPORATED 
              Under Section 805 of the Business Corporation Law 

         (as amended by the Certificate of Correction filed pursuant 
       to Section 105 of the Business Corporation Law on July 26, 1994) 

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

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

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

THIRD: This amendment of the Certificate of Incorporation was authorized by 
resolutions duly adopted by the Board of Directors of the Corporation at a 
meeting thereof duly called and held on April 28, 1994, at which a quorum was 
present and acting throughout, and by the Executive Committee of the Board of 
Directors of the Corporation, acting pursuant to delegated authority, by 
unanimous written consent on July 14, 1994. 

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

4C. Series C 6% Cumulative Convertible Preferred Stock 

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

(A) The shares of this series of Preferred Stock shall be designated as 
"Series C 6% Cumulative Convertible Preferred Stock" (the "Series C Preferred 
Stock") and the number of shares constituting such series shall be 3,737,500 
with a par value of $100 per share. 

(B) Shares of Series C Preferred Stock shall be issued only upon exchange of 
all of the 6% convertible subordinated debentures due July 21, 2024 of the 
Corporation (the "Subordinated Debentures") by Corning Delaware, L.P., a 
Delaware limited partnership ("Corning Delaware"), pursuant to a valid 
exchange election (the "Exchange Election") by the holders of a majority of 
the aggregate liquidation preference of preferred securities, liquidation 
preference of $50 per security, of Corning Delaware (the "Corning Delaware 
Preferred Securities") then outstanding. 

(C) So long as any Corning Delaware Preferred Securities are outstanding, the 
Corporation shall not issue any other class or series of capital stock 
ranking senior as to the payment of dividends or amounts upon liquidation, 
dissolution or winding-up to the Series C Preferred Stock without the 
approval of the holders of not less than 66-2/3% of the aggregate liquidation 
preference of the Corning Delaware Preferred Securities then outstanding. 

SECTION 2. Dividends and Distributions. 

(A) (1) The holders of shares of Series C Preferred Stock shall be entitled 
to receive, when, as and if declared by the Board of Directors of the 
Corporation out of funds legally available therefor, cumulative cash 
dividends in an amount per share per annum equal to $6.00 (equivalent to a 
rate per annum of 6% of the stated liquidation preference of $100 per share 
of Series C Preferred Stock), calculated on the basis of a 360-day year 
consisting of 12 months of 30 days each, and for any period shorter than a 
full monthly dividend period, dividends will be computed on the basis of the 
actual number of days elapsed in such period, and payable in United States 
dollars monthly in arrears on the last day of each calendar month of each 
year.
<PAGE>
<PAGE>
 
(2) Dividends, when, as and if declared by the Board of Directors of the 
Corporation out of funds legally available therefor, must be paid on the last 
day of each month. Such dividends will accrue and be cumulative whether or 
not they have been earned or declared and whether or not there are funds of 
the Corporation legally available for the payment of dividends. Dividends on 
the Series C Preferred Stock shall be cumulative from the date of the 
Exchange Election. Accrued but unpaid interest on the Subordinated 
Debentures, if any, on the date of the issuance of the Series C Preferred 
Stock in exchange for such Subordinated Debentures shall constitute, and be 
treated as, accumulated and unpaid dividends on the Series C Preferred Stock; 
provided, however, that the amount which shall constitute such accumulated 
and unpaid dividends on the Corning Series C Preferred Stock shall be neither 
less than nor greater than the amount of accumulated and unpaid dividends 
(including Additional Dividends), if any, on the Preferred Securities on the 
date of such Exchange Election. The record date for each dividend payment 
date shall be the Business Day (as defined below) immediately preceding such 
dividend payment date. In the event that any date on which dividends are 
payable on the Series C Preferred Stock is not a day other than a day on 
which banking institutions in The City of New York or Chicago are authorized 
or required by law to close (a "Business Day"), then payment of the dividend 
payable on such date will be made on the next succeeding day that is a 
Business Day (and without any interest or other payment in respect of any 
such delay) except that, if such Business Day is in the next succeeding 
calendar year, such payment shall be made on the immediately preceding 
Business Day, in each case with the same force and effect as if made on such 
date. 

(B) In the event that full cumulative dividends on the Series C Preferred 
Stock have not been declared and paid or set apart for payment when due, then 
the Corporation shall not, and shall not permit any majority-owned subsidiary 
to declare or pay any dividend on, or redeem, purchase, acquire for value or 
make a liquidation payment with respect to, any Junior Stock (other than as a 
result of a reclassification of Junior Stock or the exchange or conversion of 
one class or series of Junior Stock for another class or series of Junior 
Stock), or make any guarantee payments with respect to the foregoing (other 
than payments under the Guarantee or dividends or guarantee payments to 
Corning). 

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

SECTION 3. Voting Rights. 

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

(B) Except as otherwise required by law or set forth herein, holders of 
Series C Preferred Stock shall have no special voting rights and their 
consent shall not be required for the taking of any corporate action. So long 
as any shares of Series C Preferred Stock are outstanding, the consent of the 
holders of not less than 66-2/3% of the outstanding shares of Series C 
Preferred Stock, given in person or by proxy either at a regular meeting or 
at a special meeting called for that purpose, at which the holders of Series 
C Preferred Stock shall vote separately as a series, shall be necessary for 
effecting, validating or authorizing any one or more of the following: 
(1) the amendment, alteration or repeal of any of the provisions of the 
Certificate of Incorporation, as amended, of the Corporation, or any 
amendment thereto or any other certificate filed pursuant to law (including 
any such amendment, alteration or repeal effected by any merger or 
consolidation to which the Corporation is a party) that would adversely 
affect any of the rights, powers or preferences of outstanding shares of 
Series C Preferred Stock, provided, however, that the amendment of the 
provisions of the Certificate of Incorporation so as to authorize or create, 
or increase the authorized amount of, any Junior Stock or Pari Passu Stock 
shall not be deemed to affect adversely the voting powers, rights or 
preferences of the holders of the Series C Preferred Stock; 

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

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

SECTION 4. Redemption. 

(A) The shares of Series C Preferred Stock are redeemable, at the option of 
the Corporation, in whole or in part from time to time, on or after August 5, 
1998 during the twelve-month periods beginning on August 5 in each of the 
following years, at the following redemption prices (expressed as a 
percentage of liquidation preference), plus accumulated and unpaid dividends, 
whether or not earned or declared, to the date of redemption (the "Redemption 
Price"):

August 5, 2004 and thereafter                     100.0% 
</TABLE>
From and after the date fixed for redemption, dividends on shares of Series C 
Preferred Stock called for redemption will cease to accrue, such shares will 
no longer be deemed to be outstanding and all rights in respect of such 
shares of the Corporation shall cease, except the right to receive the 
Redemption Price, provided that shares of Series C Preferred Stock may be 
converted pursuant to Section 6 hereof at any time prior to the close of 
business on the date fixed for redemption of such shares. If less than all of 
the outstanding shares of Series C Preferred Stock are to be redeemed, the 
Corporation shall either redeem a portion of the shares held by each holder 
or shall select the shares to be redeemed by lot, as may be determined by the 
Board of Directors of the Corporation. 

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

SECTION 5. Liquidation, Dissolution or Winding-Up. 

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

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

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

SECTION 6. Conversion Rights of Series C Preferred Stock. 

(A) The shares of Series C Preferred Stock are convertible at any time at the 
option of the holder thereof into shares of Common Stock at the initial 
conversion price $39.00, subject to adjustment as provided in Section 7. For 
this purpose, each share of Series C Preferred Stock shall be taken at 
$100.00. 

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

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

(D) Shares of Series C Preferred Stock that have been called for redemption 
will not be convertible after the close of business on the second calendar 
day preceding the date fixed for redemption, unless the Corporation defaults 
in making payment of the amount payable upon such redemption. 

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

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

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

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

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

SECTION 7. Adjustment of Conversion Price. 

(A) Adjustment of Conversion Price. The conversion price at which a share of 
Series C Preferred Stock is convertible into Common Stock shall be subject to 
adjustment from time to time as follows: 
(i) In case the Corporation shall pay or make a dividend or other 
distribution on any class or series of capital stock of the Corporation 
exclusively in Common Stock, the conversion price in effect at the opening
<PAGE>
<PAGE>
 
of business on the day following the date fixed for the determination of 
stockholders entitled to receive such dividend or other distribution shall be 
reduced by multiplying such conversion price by a fraction of which the 
numerator shall be the number of shares of Common Stock outstanding at the 
close of business on the date fixed for such determination and the 
denominator shall be the sum of such number of shares and the total number of 
shares constituting such dividend or other distribution or exchange, such 
reduction to become effective immediately after the opening of business on 
the day following the date fixed for such determination. For the purposes of 
this subparagraph (i), the number of shares of Common Stock at any time 
outstanding shall not include shares held in the treasury of the Corporation. 
The Corporation shall not pay any dividend or make any distribution on shares 
of any class or series of capital stock of the Corporation exclusively in 
Common Stock held in the treasury of the Corporation. 

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

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

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

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

(vi) In case a tender or exchange offer made by the Corporation or any 
subsidiary of the Corporation for all or any portion of the Corporation's 
Common Stock shall expire and such tender or exchange offer shall involve the 
payment by the Corporation or such subsidiary of consideration per share of 
Common Stock having a fair market value (as determined in good faith by the 
Board of Directors, whose determination shall be conclusive and described in 
a resolution of the Board of Directors) at the last time (the "Expiration 
Time") tenders or exchanges may be made pursuant to such tender or exchange 
offer (as it shall have been amended) that exceeds 10% of the current market 
price per share (determined as provided in subparagraph (vii) of this Section 
7(A)) of the Common Stock on the Trading Day next succeeding the Expiration 
Time, the conversion price shall be reduced so that the same shall equal the 
price determined by multiplying the conversion price in effect immediately 
prior to the effectiveness of the conversion price reduction contemplated by 
this subparagraph (vi) by a fraction of which the numerator shall be the 
number of shares of Common Stock outstanding (including any tendered or 
exchanged shares) at the Expiration Time multiplied by the current market 
price per share (determined as provided in subparagraph (vii) of this Section 
7(A)) of the Common Stock on the Trading Day next succeeding the Expiration 
Time and the denominator shall be the sum of (x) the fair market value 
(determined as aforesaid) of the aggregate consideration payable to 
stockholders based on the acceptance (up to any maximum specified in the 
terms of the tender or exchange offer) of all shares validly tendered or 
exchanged and not withdrawn as of the Expiration Time (the shares deemed so 
accepted, up to any such maximum, being referred to as the "Purchased 
Shares") and (y) the product of the number of shares of Common Stock 
outstanding (less any Purchased Shares) at the Expiration Time and the 
current market price per share (determined as provided in subparagraph (vii) 
of this Section 7(A)) of the Common Stock on the Trading Day next succeeding 
the Expiration Time, such reduction to become effective immediately prior to 
the opening of business on the day following the Expiration Time. 
Notwithstanding anything contained in this Section 7(A)(vi) to the contrary, 
no adjustment shall be made to the conversion price in the case of a tender 
offer that complies with Rule 13e-4(h)(5) under the Exchange Act, or any 
successor rule thereto. 

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

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

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

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

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

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

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

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

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

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

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

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

For purposes of calculating any adjustment to be made pursuant to this 
Section 7(D) in the event of a Fundamental Change, immediately after such 
Fundamental Change: 
(i) in the case of a Non-Stock Fundamental Change (as defined in Section

adjustments effected pursuant to this Section 7, and (B) the result obtained 
by multiplying the greater of the Applicable Price (as defined in Section

Series C Preferred Stock or (y) for any Non-Stock Fundamental Change that 
occurs before the Series C Preferred Stock becomes redeemable by the 
Corporation pursuant to Section 4, the applicable price per share set forth

  plus, in any case referred to in this clause (y), an amount equal to all 
dividends on the Series C Preferred Stock accrued and unpaid thereon, whether 
or not earned or declared, to but excluding the date of such Non-Stock 
Fundamental Change; and 
(ii) in the case of a Common Stock Fundamental Change, the conversion price 
of the Series C Preferred Stock in effect immediately prior to such Common 
Stock Fundamental Change, but after giving effect to any other prior 
adjustments effected pursuant to this Section 7, shall thereupon be adjusted 
by multiplying such conversion price by a fraction of which the numerator 
shall be the Purchaser Stock Price (as defined in Section 7(E)) and the 
denominator shall be the Applicable Price; provided, however, that in the 
event of a Common Stock Fundamental Change in which (A) 100% by value of the 
consideration received by a holder of Common Stock is common stock of the 
successor, acquiror or other third party (and cash, if any, is paid with 
respect to any fractional interests in such common stock resulting from such 
Common Stock Fundamental Change) and (B) all of the Common Stock shall have 
been exchanged for, converted into or acquired for common stock (and cash 
with respect to fractional interests) of the successor, acquiror or other 
third party, the conversion price of the Series C Preferred Stock in effect 
immediately prior to such Common Stock Fundamental Change shall thereupon be 
adjusted by multiplying such conversion price by a fraction of which the 
numerator shall be one (1) and the denominator shall be the number of shares 
of common stock of the successor, acquiror, or other third party received by 
a stockholder for one share of Common Stock as a result of such Common Stock 
Fundamental Change. 

(E) Definitions. The following definitions shall apply to terms used in this 
Section 7: 
(1) "Applicable Price" shall mean (i) in the event of a Non-Stock Fundamental 
Change in which the holders of the Common Stock receive only cash, the amount 
of cash received by a stockholder for one share of Common Stock and (ii) in 
the event of any other Non-Stock Fundamental Change or any Common Stock 
Fundamental Change, the average of the daily Closing Prices of the Common 
Stock for the ten consecutive Trading Days prior to and including the record 
date for the determination of the holders of Common Stock entitled to receive 
securities, cash or other property in connection with such Non-Stock 
Fundamental Change or Common Stock Fundamental Change, or, if there is no 
such record date, the date upon which the holders of the Common Stock shall 
have the right to receive such securities, cash or other property, in each 
case, as adjusted in good faith by the Board of Directors of the Corporation 
to appropriately reflect any of the events referred to in subparagraphs (i), 
(ii), (iii), (iv), (v) and (vi) of Section 7(A). 

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

(3) "Common Stock Fundamental Change" shall mean any Fundamental Change in 
which more than 50% by value (as determined in good faith by the Board of 
Directors of the Corporation) of the consideration received by holders of 
Common Stock consists of common stock that for each of the ten consecutive 
Trading Days referred to with respect to such Fundamental Change in Section 
7(E)(1) above has been admitted for listing or admitted for listing subject 
to notice of issuance on a national securities exchange or quoted on the 
National Market System of the National Association of Securities Dealers, 
Inc.; provided, however, that a Fundamental Change shall not be a Common 
Stock Fundamental Change unless either (i) the Corporation con
<PAGE>
<PAGE>
 
tinues to exist after the occurrence of such Fundamental Change and the 
outstanding shares of Series C Preferred Stock continue to exist as 
outstanding shares of Series C Preferred Stock, or (ii) not later than the 
occurrence of such Fundamental Change, the outstanding shares of Series C 
Preferred Stock are converted into or exchanged for shares of convertible 
preferred stock of a corporation succeeding to the business of the 
Corporation, which convertible preferred stock has powers, preferences and 
relative, participating, optional or other rights, and qualifications, 
limitations and restrictions, substantially similar to those of the Series C 
Preferred Stock. 

(4) "Fundamental Change" shall mean the occurrence of any transaction or 
event in connection with a plan pursuant to which all or substantially all of 
the Common Stock shall be exchanged for, converted into, acquired for or 
constitute solely the right to receive securities, cash or other property 
(whether by means of an exchange offer, liquidation, tender offer, 
consolidation, merger, combination, reclassification, recapitalization or 
otherwise); provided, however, in the case of a plan involving more than one 
such transaction or event, for purposes of adjustment of the conversion 
price, such Fundamental Change shall be deemed to have occurred when 
substantially all of the Common Stock of the Corporation shall be exchanged 
for, converted into, or acquired for or constitute solely the right to 
receive securities, cash or other property, but the adjustment shall be based 
upon the highest weighted average of consideration per share which a holder 
of Common Stock could have received in such transactions or events as a 
result of which more than 50% of the Common Stock of the Corporation shall 
have been exchanged for, converted into, or acquired for or constitute solely 
the right to receive securities, cash or other property. 

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

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

(7) "Reference Market Price" shall initially mean $21.42 and in the event of 
any adjustment to the conversion price other than as a result of a Non-Stock 
Fundamental Change, the Reference Market Price shall also be adjusted so that 
the ratio of the Reference Market Price to the conversion price after giving 
effect to any such adjustment shall always be the same as the ratio of $21.42 
to the initial conversion price per share. 

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

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

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

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

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

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

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

SECTION 9. Miscellaneous. 

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

(B) The term "Common Stock" as used in this paragraph 4C means the 
Corporation's Common Stock, par value $0.50 per share, as the same exists at 
the date of filing of a Certificate of Amendment to the Certificate of 
Incorporation of the Corporation relating to the Series C Preferred Stock or 
any other class of stock resulting from successive changes or 
reclassifications of such Common Stock consisting solely of changes in par 
value, or from par value to no par value, or from no par value to par value. 
However, subject to the provisions of Section 7(B), shares of Common Stock 
issuable on conversion of shares of Series C Preferred Stock shall include 
only shares of the class designated as Common Stock of the Corporation at the 
date of the filing of this instrument with the State of New York or shares of 
any class or classes resulting from any reclassification or reclassifications 
thereof and which have no preference in respect of dividends or of amounts 
payable in the event of any voluntary or involuntary liquidation, dissolution 
or winding-up of the Corporation and which are not subject to redemption by 
the Corporation; provided that if at any time there shall be more than one 
such resulting class, the shares of each such class then so issuable shall be 
substantially in the proportion which the total number of shares of such 
class resulting from all such reclassifications bears to the total number of 
shares of such classes resulting from all such reclassifications.
<PAGE>
<PAGE>
 
(C) The Corporation shall pay any and all stock transfer and documentary 
stamp taxes that may be payable in respect of any issuance or delivery of 
shares of Series C Preferred Stock or shares of Common Stock or other 
securities issued on account of Series C Preferred Stock pursuant hereto or 
certificates representing such shares or securities. The Corporation shall 
not, however, be required to pay any such tax that may be payable in respect 
of any transfer involved in the issuance or delivery of shares of Series C 
Preferred Stock or Common Stock or other securities in a name other than that 
in which the shares of Series C Preferred Stock with respect to which such 
shares or other securities are issued or delivered were registered, or in 
respect of any payment to any person with respect to any such shares or 
securities other than a payment to the registered holder thereof, and shall 
not be required to make any such issuance, delivery or payment unless and 
until the person otherwise entitled to such issuance, delivery or payment has 
paid to the Corporation the amount of any such tax or has established, to the 
satisfaction of the Corporation, that such tax has been paid or is not 
payable. 

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

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

Ladies & Gentlemen: 

I refer to the registration statement on Form S-4 (the "Registration 
Statement") being filed by Corning Incorporated, a New York corporation 
("Corning"), with the Securities and Exchange Commission under the Securities 
Act of 1933, as amended (the "Securities Act"), relating to the registration 
of up to 9,766,033 shares of common stock, par value $0.50 per share, of 
Corning (the "Shares"), to be issued in connection with the merger of Nichols 
Institute and a subsidiary of Corning, as described in the Agreement and Plan 
of Merger, dated June 1, 1994, as amended, attached as Appendix A to the 
Proxy Statement/Prospectus forming a part of the Registration Statement (the 
"Merger Agreement"). 

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

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

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

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

I hereby consent to the filing of this opinion as an Exhibit to the 
Registration Statement and to all references to me included in the Proxy 
Statement/Prospectus forming a part of the Registration Statement. 
                                            Very truly yours,
