               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference

         The following document filed with the Securities and Exchange
Commission is incorporated herein by reference:

         Amendment No. 4 to the Registration Statement on Form 10 (File
         No.1-12215) filed by the Company and declared effective on November 26,
         1996.

All documents filed by the Company pursuant to Section 13(a) or 15(d) of the
Securities Exchange Act prior to the filing of a post-effective Amendment which
indicates that all securities offered have been sold or which deregisters all
securities then remaining unsold shall be deemed to be incorporated by reference
in this Registration Statement and to be a part hereof from the date of filing
of such documents.

Item 5. Interests of Named Experts and Counsel

         Leo C. Farrenkopf, Jr. Esq., Vice President and Associate General
Counsel of the Company, has rendered an opinion as to the legality of the shares
of the Common Stock offered pursuant to this Registration Statement. Mr.
Farrenkopf owns substantially less than 1% of the Company's Common Stock.

Item 6.  Indemnification of Directors and Officers

Limitation on Liability of Directors

         Pursuant to authority conferred by Section 102 of the Delaware General
Corporation Law ("DGCL") Paragraph 11 of the Company's Certificate of
Incorporation ("Paragraph 11") eliminates the personal liability of the
Company's directors to the Company or its stockholders for monetary damages for
breach of fiduciary duty, including without limitation, directors serving on
committees of the Company's Board of Directors. Directors remain liable for (1)
any breach of the duty of loyalty to the Company or its stockholders, (2) any
act or omission not in good faith or which involves intentional misconduct or a
knowing violation of law, (3) any violation of Section 174 of the DGCL, which
proscribes the payment of dividends and stock purchases or redemption under
certain circumstances, and (4) any transaction from which directors derive an
improper personal benefit.

Indemnification and Insurance

         In accordance with Section 145 of the Delaware General Corporation Law
("DGCL"), which provides for the indemnification of directors, officers and
employees under certain circumstances, Paragraph 11 grants the Company's
directors and officers a right to indemnification for all expenses, liabilities
and losses relating to civil, criminal, administrative or investigative
proceedings to which they are a party (1) by reason of the fact that they are or
were directors or officers of Company, or (2) by reason of the fact that, while
they are or were directors or officers of the Company , they are serving at the
request of the Company as directors or officers of another corporation,
partnership, joint venture, trust or enterprise. Paragraph 11 further provides
for the mandatory advancement of expenses incurred by officers and directors in
defending such proceedings in advance of their final disposition upon delivery
to the Company by the indemnitee of an undertaking to repay all amounts so
advanced if it is ultimately determined that such indemnitee is not entitled to
be indemnified under Paragraph 11. The Company may not indemnify or make
advanced payments to any person in connection with proceedings initiated against
the Company by such person without authorization of the Company's Board of
Directors.

         In addition, Paragraph 11 provides that the directors and officers
therein described shall be indemnified to the fullest extent permitted by
Section 145 of DGCL, or any successor provision or amendments thereunder. In the
event that any such successor provisions or amendments provide indemnification
rights broader than permitted prior thereto, Paragraph 11 allows such broader
indemnification rights to apply retroactive with respects to any predating
alleged action or inaction and also allows the indemnification to continue after
an






indemnitee has ceased to be a director or officer of the Company and to inure to
the benefit of the indemnitee's heirs, executors and administrators.

         Paragraph 11 further provides that the right to indemnification is not
exclusive of any right which any indemnitee may have or thereafter acquire under
any statute, the Company's Certificate of Incorporation, any agreement or vote
of stockholders or disinterested directors or otherwise, and allows the Company
to indemnify and advance expenses to any person whom the Company has the power
to indemnify under the DGCL or otherwise.

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

         The Company's Certificate of Incorporation authorizes the Company to
purchase insurance for directors and officers of the Company and persons who
serve at the request of the Company as directors, officers, employees or agents
of another corporation, partnership, joint venture, trust, or enterprise,
against any expense, liability or loss incurred in such capacity, whether or not
the Company would have the power to indemnify such persons against such expense
or liability under the DGCL. The Company intends to maintain insurance coverage
of its officers and directors as well as insurance coverage to reimburse the
Company for potential costs of its corporate indemnification of directors and
officers.

Item 9. Undertakings

         (a) The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement;

         (i) To include any prospectus required by section 10(a)(3) of the
Securities Act of 1933;

         (ii) To include in any prospectus any facts or events arising after the
effective date of the registration statement (or the most recent post-effective
amendment thereof) which individually or in the aggregate, represent a
fundamental change in the information set forth in the registration statement;
notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if in the aggregate the
changes in volume and price represents no more than a 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement;








         (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement.

Provided, however, the paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
section 13 or section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act
of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

(b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing 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.

(c) The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and where interim financial information required to be presented by
Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

(d) Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of
such issue.

                                                               November 26, 1996

Securities and Exchange Commission

Dear Sirs:

         I am Vice President and Associate General Counsel of Corning Clinical
Laboratories Inc. (the Company) and am familiar with the preparation and filing
of a registration statement on Form S-8 under the Securities Act of 1933, as
amended, with respect to an aggregate of 1.5 million shares of the Company's
Common Stock, $.01 par value, which may be sold by the Company pursuant to its
Profit Sharing Plan (the "Plan").

         In this connection, I have examined the originals, or copies certified
to my satisfaction, of such corporate records of the Company, certificates of
public officials and officers of the Company, and other documents as I deemed
pertinent as a basis for the opinions hereinafter expressed.

Based upon the foregoing, and having regard for such legal consideration as I
have deemed relevant, I am of the opinion that:

         1.    The Company is a corporation duly incorporated and validly
               existing under the laws of the State of Delaware.

         2.    The shares of the Company's Common Stock to be sold by the
               Company pursuant to the Plan will be duly authorized, validly
               issued, fully paid and non-assessable.

         3.    The Company undertakes to submit to the Internal Revenues Service
               all amendment to the Plan for a determination letter that the
               Plan as amended is qualified under Section 401(a) of the
               Internal Revenue Code of 1986. The Plan is subject to the
               provisions of the Employee Retirement Income Security Act of
               1974.

         I consent to the filing of this opinion as an Exhibit to the
Registration statement referred to above.

                                                 Very truly yours.
