8.       Inventions.

         With respect to Inventions made or conceived by the Employee, whether
or not during the hours of his employment or with the use of the Company
facilities, materials, or personnel, either solely or jointly with others during
his employment by the Company, or within two (2) years after termination of such
employment if based on or related to Confidential Information:

                  (a) The Employee shall inform the Company promptly and fully
of such Inventions by a written report, setting forth in detail a description of
the Invention and any processes associated with its promotion. A detailed
written report also will be submitted by the Employee upon completion of any

techniques, as well as improvements thereof or know-how related thereto, which
are not within the scope of Inventions as defined herein but which are conceived
or made by the Employee during the hours which he is employed by the Company or
with the use or assistance of the Company's facilities, materials or personnel.

9.       Restrictive Covenants.

         9.1 Employee agrees that he will not, either during his employment or
at any time after cessation of such employment, impart or disclose any of the
Confidential Information to any person, firm or corporation other than Company,
or use any of such Confidential Information, directly or indirectly for the
Employee's own benefit or for the benefit of any person, firm or corporation
other than Company or its affiliates. Employee's obligations under this Section
9.1 shall cease with respect to any such Confidential Information if such
information (i) was already known to Employee at the time of disclosure, free of
any obligation to keep it confidential, or (ii) was subsequently disclosed to
Employee without breach of this Agreement by a third person who rightfully
received and disclosed it without breaching any confidentiality obligation to
the Company. It is also understood by the parties that Employee may be required
to 
   9
                                      -9-


disclose Confidential Information (a) pursuant to subpoena or other court
process, (b) at the express direction of any other authorized government agency
or (c) otherwise as required by law or regulation. Disclosure of Confidential
Information or any part thereof in such circumstances will not constitute a
breach of the confidentiality provisions set forth in this Agreement, provided
that Employee notifies Company in advance of any such disclosure and cooperates
with Company in any efforts that Company may make to seek a protective order
with respect to such disclosure.

         9.2 In addition to the foregoing agreements relating to the Company's
Confidential Information, during the term of this Agreement (including any
renewals thereof) and during the term of the "Post-Employment Period" (as
defined herein), Employee will not, without the Company's prior written consent,
(i) solicit any of the employees of Company for the purpose of hiring or
retaining any such employees, (ii) hire or retain or cause to be hired or
retained any of the employees of Company or (iii) become involved in any manner,
including without limitation as an officer, director, employee, consultant,
representative, xxanner, owner or shareholder (except as a holder of less than a
two percent (2%) equity interest in a public entity) in any business located in
the United States which is in the business of inventing, developing,
manufacturing, marketing, providing or selling products competitive with the
products that the Company has developed, manufactured, marketed, produced or
sold, or is in the process of developing (and reasonably expect to bring to
market within one (1) year after the expiration or the Post-Employment Period or
longer if required by the U.S. Food and Drug Administration 
   10
                                      -10-


clearance or approval process), manufacturing, marketing, producing or selling
as of the date that Employee's employment terminates. For purposes of this
Agreement, the term "Post Employment Period" shall mean the period commencing on
the date that this Agreement is terminated for any reason and ending two (2)
years from the date of such termination.

         9.3 Employee agrees that all memoranda, lab books, notes, records,
charts, formulae, specifications, lists and other documents made, compiled,
received, held or used by Employee while employed by Company, concerning any
phase of Company's business or its Confidential Information, shall be Company's
property and shall be delivered by Employee to Company upon termination of
Employee's employment or at any earlier time on the request of Company.

         9.4 Employee acknowledges that given his access to information
regarding Company, the provisions of this Section 9 are reasonable and necessary
to protect Company's business. Employee further acknowledges that Employee has
carefully reviewed the provisions of this Section 9, that Employee fully
understands the economic consequences thereof, that Employee has assessed the
respective advantages and disadvantages to Employee of entering into this
Agreement and Employee has concluded that, in light of Employee's education,
skills and abilities, the restrictions set forth in this Section 9 will not
prevent Employee from earning a living after the termination of this Agreement.
Employee agrees that each of the provisions of this Section 9, including,
without limitation. the period of time, geographical area and types and scope of
the restrictions on Employee's activities specified herein, are intended to be
and shall be divisible. Employee further acknowledges that reasonableness of
these provisions as an integral 
   11
                                      -11-


part of the terms of Employee's employment. If any provision of this Section 9
(including any sentence, clause or part thereof) shall be adjudicated to be
invalid or unenforceable, such provision shall be deemed amended to delete
therefrom the portion thus adjudicated to be invalid or unenforceable such
deletion to apply only with respect to the operation of such provision in the
particular jurisdiction in which such adjudication is made. In addition, if any
particular provision contained in this Agreement shall for any reason be held to
be excessively broad as to duration, geographical scope, activity or subject, it
shall be construed by limiting and reducing such provision as to such
characteristic so that the provision is enforceable to the fullest extent
compatible with the applicable law as it shall then appear.

         9.5 As it would be very difficult to measure the damages which would
result to Employer from a breach of any of the covenants contained in this
Section 9, in the event of such a breach, Company shall have the right to have
such covenants specifically enforced by a court of competent jurisdiction.
Employee hereby recognizes and acknowledges that irreparable injury or damage
shall result to the business of Company in the event of a breach or threatened
breach by Employee of the terms and provisions of this Section 9. Therefore,
Employee agrees that Company shall be entitled to an injunction restraining
Employee from engaging in any activity constituting such breach or threatened
breach. Nothing contained herein shall be construed as prohibiting Company from
pursuing any other remedies available to Company at law or in equity for such
breach or threatened breach, including, but not limited to, recovery of damages
from 
   12
                                      -12-


Employee and, if Employee is still employed by Company, terminating the
employment of Employee in accordance with the terms and provisions hereof.

affected, and the Agreement shall thereafter be construed as if the invalid
provision had not been included in the Agreement, unless the elimination of such
provision destroys the underlying business purpose of this Agreement.
