                            NONCOMPETITION AGREEMENT
 
     THIS NONCOMPETITION AGREEMENT (the "Agreement") is made and entered this
10th day of February 1997, by and between JOHNSON & JOHNSON, a New Jersey
corporation ("J&J"), and HORACE N. HUDSON, an individual (the "Stockholder").
 
                              W I T N E S S E T H
 
     WHEREAS, the Stockholder is a stockholder of Innotech, Inc., a Delaware
corporation (the "Company"), and is also a key executive officer of the Company;
and
 
     WHEREAS, pursuant to, and subject to the terms and conditions of, an
Agreement and Plan of Merger with the Company (the "Merger Agreement"), J&J
through a subsidiary ("Sub") will make a tender offer (the "Offer") to purchase
all the issued and outstanding shares of capital stock of the Company (the
"Shares"), and the now existing stockholders of the Company will receive a cash
payment per share constituting a significant premium to the market price of the
stock of the Company; and
 
     WHEREAS, the Board of Directors of the Company has adopted resolutions
approving the Offer and the subsequent merger of Sub into the Company (the
"Merger"), upon the terms and subject to the conditions set forth in the Merger
Agreement; and
 
     WHEREAS, following the Merger, J&J intends, or intends to cause Sub, to
continue to conduct and operate the business of the Company; and
 
     WHEREAS, as an inducement to J&J to enter into the Merger Agreement and to
acquire the Company stock owned by (and to pay the amount set forth in Section
7.04(a) of the Merger Agreement in respect of the Company stock options held by)
the Stockholder, the Stockholder is entering into this Agreement:
 
     NOW, THEREFORE, in consideration of the foregoing and the mutual agreements
hereinafter set forth, the parties hereto agree as follows:
 
          1.  Noncompetition.  (a) The Stockholder agrees that for the period of
     the Stockholder's employment following the Closing with J&J, or any
     subsidiary thereof, and for two (2) years following the termination of such
     employment (regardless of the circumstances under which such employment is
     terminated) (such period, the "Noncompetition Period"), the Stockholder
     will not have any Relationship (as defined below) with any entity,
     including but not limited to any corporation, partnership, limited
     liability company, sole proprietorship or unincorporated business (whether
     or not for profit) (such entity, a "Business") in the course of which
     Relationship the Stockholder engages in or assists such Business with
     respect to the ophthalmic spectacle lens business (which business shall not
     include lens analyzing equipment) ("Lens Products and Services").
 
          (b) In the event that the Company terminates the Stockholder's
     employment without Cause (as defined below), the Company shall (x) continue
     to pay such Stockholder through the end of the Noncompetition Period
     (payable in accordance with the regular payroll practices of the Company)
     an annual amount equal to the salary that the Stockholder was receiving
     immediately prior to such termination and (y) continue to provide all
     benefits generally available under employee benefit plans or the practices
     and policies of the Company at the time of such termination (other than
     stock option or similar plans), determined in accordance with the
     provisions of such plans, practices and policies. "Cause" shall mean (i)
     Stockholder's conviction of, guilty plea to, or confession of guilt of, a
     felony, (ii) dishonest or illegal conduct or misconduct or malfeasance by
     the Stockholder in the performance of services for or on behalf of the
     Company, or other conduct detrimental to the business, operations or
     reputation of the Company, regardless of whether such conduct is within the
     scope of Stockholder's duty, (iii) failure by the Stockholder to perform
     his duties, as assigned to him by the President from time to time, provided
     that such duties are not inconsistent with the Stockholder's current
     duties, or
   2
 
     (iv) violation by the Stockholder of the covenants set forth in this
     Agreement; provided, however, that "Cause" shall, in no circumstances mean
     the failure by the Stockholder to relocate in the event the Company
     relocates its place of business and the Stockholder is unable to perform
     his duties without so relocating.
 
          (c) The Stockholder will be deemed to have a relationship (a
     "Relationship") with a Business if such Stockholder (i) owns, manages,
     operates, joins, or is employed by such Business, (ii) is a director,
     member, agent, shareholder, owner or general partner of such Business,
     (iii) acts as a consultant or advisor to such Business or (iv) controls or
     participates in the ownership, management or operation of, such Business;
     provided however, that nothing herein shall prevent the purchase or
     ownership by the Stockholder (and his "associates" as defined by the
     Securities and Exchange Commission's Proxy Rules) of an interest in a
     Business that constitutes less than 5% of the outstanding equity securities
     of such Business.
 
          2.  Nonsolicitation of Clients.  During the Noncompetition Period, the
     Stockholder agrees that he will not directly or indirectly provide Lens
     Products and Services (whether as an employee, consultant, advisor or
     otherwise) to any entity that at such time is, or at any time in the twelve
     (12) month period prior to such time had been, a customer of the Company
     unless (a) the Stockholder is employed by J&J or a subsidiary thereof and
     such solicitation is made on behalf of, or payment for the performance of
     such services is made to, such employer or (b) the Stockholder shall have
     previously obtained a written release specifically permitting an action
     that would otherwise be prohibited by the provisions of this Paragraph 2.
 
          3.  Nonsolicitation of Employees and Consultants.  During the
     Noncompetition Period, the Stockholder agrees that he will not directly or
     indirectly solicit, influence, entice or encourage any person who at such
     time is, or who at any time in the three (3) month period prior to such
     time had been, an employee of or consultant to the Company or J&J to cease
     or curtail his or her relationship therewith.
 
          4.  Nondisruption; Other Matters.  During the Noncompetition Period,
     the Stockholder agrees that he will not directly or indirectly interfere
     with, disrupt or attempt to disrupt any past, present or prospective
     relationship, contractual or otherwise, between the Company or J&J, on the
     one hand, and any of their respective customers, suppliers or employees, on
     the other hand.
 
          5.  Confidential Information.  The Stockholder covenants and agrees
     that, during the Noncompetition Period, he shall not use for his own behalf
     or divulge to any other person or entity any confidential information or
     trade secrets of or relating to the Company. The Stockholder further
     covenants and agrees that, during the Noncompetition Period, he shall not
     take or remove from the property of the Company any documentary copies,
     records or materials containing any such confidential information or trade
     secrets. As used herein, confidential information shall consist of all
     information, knowledge or data relating to the Company or J&J (including
     all information relating to inventions, production methods, customer and
     prospective customer lists, prices and trade practices) which is not in the
     public domain or otherwise published or publicly available.
 
          6.  Equitable Relief.  The Stockholder acknowledges and agrees that
     J&J's remedies at law for breach of any of the provisions of this Agreement
     would be inadequate and, in recognition of this fact, the Stockholder
     agrees that, in the event of such breach, in addition to any remedies at
     law it may have, J&J, without posting any bond, shall be entitled to obtain
     equitable relief in the form of specific performance, a temporary
     restraining order, a temporary or permanent injunction or any other
     equitable remedy that may be available. The Stockholder further
     acknowledges that should the Stockholder violate any of the provisions of
     this Agreement, it will be difficult to determine the amount of damages
     resulting to J&J or its affiliates and that in addition to any other
     remedies it may have J&J shall be entitled to temporary and permanent
     injunctive relief.
 
          7.  Merger Agreement.  J&J represents that concurrently with the
     execution of this Agreement, J&J is executing the Merger Agreement, and
     subject to the terms of the Merger Agreement will cause the Offer to be
     commenced as provided in the Merger Agreement.

          8.  Acknowledgement.  Each of the Stockholder and J&J acknowledges and
     agrees that the covenants and agreements contained in this Agreement have
     been negotiated in good faith by the parties, and are reasonable and are
     not more restrictive or broader than necessary to protect the interests of
     the parties hereto, and would not achieve their intended purpose if they
     were on different terms or for periods of time shorter than the periods of
     time provided herein or applied in more restrictive geographical areas than
     are provided herein. Each party further acknowledges that J&J would not
     enter into the Merger Agreement and the transactions contemplated thereby
     (including, without limitation, the purchase of the Shares held by the
     Stockholder and payment in respect of the stock options granted to him by
     the Company) in the absence of the covenants and agreements contained in
     this Agreement and that such covenants and agreements are essential to
     protect the value of the Company.
 
          9.  Reasonableness of Provisions; Severability.  The Stockholder
     expressly understands and agrees that although both he and J&J consider the
     covenants and agreements contained in this Agreement, including the
     restrictions contained in Paragraphs 1, 2, 3, 4, and 5, to be reasonable,
     if a final judicial determination is made by a court of competent
     jurisdiction that the time or territory restrictions contained herein, or
     any other provision or restriction contained herein, is an unenforceable
     provision or restriction against the Stockholder, the provisions and
     restrictions of this Agreement shall not be rendered void but shall be
     deemed amended to apply as to such maximum time and territory and to such
     maximum extent as such court may judicially determine or indicate to be
     enforceable. Alternatively, if any court of competent jurisdiction finds
     that any provision or restriction contained in this Agreement is
     unenforceable, and such provision or restriction cannot be amended so as to
     make it enforceable, such finding shall not affect the enforceability of
     any of the remaining provisions and restrictions contained herein, which
     remaining provisions and restrictions shall be deemed severable from the
     unenforceable provision or restriction and shall remain in full force and
     effect.
 
          10.  Not an Employment Agreement.  This Agreement is not, and nothing
     in this Agreement shall be construed as, an agreement to provide employment
     to the Stockholder. The provisions of Paragraphs 1, 2, 3, 4, and 5 of this
     Agreement shall be operative regardless of the reasons for any termination
     of the Stockholder's employment and regardless of the performance or
     nonperformance by any party under any other section of this Agreement.
 
          11.  Governing Law.  This Agreement is made under and shall be
     governed by, construed in accordance with and enforced under the laws of
     the State of New York, without regard to conflict of laws provisions of New
     York law.
 
          12.  Entire Agreement.  This Agreement together with the Merger
     Agreement and the Stockholder Agreement (as defined in the Merger
     Agreement) constitutes and contains the entire agreement and understanding
     concerning the subject matter addressed herein between the parties, and
     supersedes and replaces all prior negotiations and all agreements proposed
     or otherwise, whether written or oral, concerning the subject matter
     hereof, and the parties hereto have made no agreements, representations or
     warranties relating to the subject matter of this Agreement that are not
     set forth herein or in the Merger Agreement or the Stockholder Agreement.
