                              GENERAL PROVISIONS TO
                          EMPLOYMENT AGREEMENT BETWEEN
                                EMBREX, INC. AND
                        Hayes Fenstermacher ("EMPLOYEE")
                            PERSONAL AND CONFIDENTIAL

1.  EMPLOYMENT

    EMBREX hereby employs Employee and Employee accepts such employment and
agrees to perform for EMBREX the duties described herein, faithfully and to the
best of his ability.

2.  TERM OF EMPLOYMENT

    Employee's employment hereunder shall commence on the date noted on the
cover letter and shall continue at the pleasure of the Company. A probationary
period of 90 days shall be observed, so long as Employee is performing at a
satisfactory level. At the conclusion of probationary period, Employee shall be
given a performance evaluation.

3.  DUTIES

    Employee agrees to devote his full time and attention to the business and
affairs of EMBREX, to use his best efforts to promote the interests of EMBREX,
to hold such offices in EMBREX to which he may be elected or appointed, and to
perform such tasks, commensurate with his position, as are assigned to him by
the President and CEO or other individuals designated by him.

4.  COMPENSATION

    4.1 EMBREX will pay Employee, for services rendered hereunder, a salary at
the rate of not less than the minimum salary per annum stated in the offer
letter, payable in equal monthly installments. The Company will review this base
salary on an annual basis and will determine in its sole discretion whether to
provide a merit increase to the base salary.

    4.2 The parties hereto agree that Employee shall be entitled to participate
in all retirement, profit-sharing, compensation, insurance or other benefit
plans presently in effect or which may be generally established during the term
hereof for employees at EMBREX.

    4.3 The terms and conditions of employment (salary, equity and/or other
forms of compensation) are strictly a personal matter between Employee and the
Company and will be shared only with Employee's supervisors having salary
administration responsibility.

5.  EXPENSES

    EMBREX will reimburse Employee for all expenses which are reasonably
incurred by him in the performance of his duties in furtherance of or in
connection with the business of EMBREX or its subsidiaries.

6.  INCAPACITY, RETIREMENT, OR DEATH

    In the event that Employee shall become incapacitated from performing the
duties of his employment hereunder (other than by death) for a continuous period
of 60 days or an aggregate of four months during the term hereof (both periods
hereinafter referred to as the "Disability Period"), Employee nevertheless shall
be entitled to all compensation and other payments provided for hereunder during
the Disability Period and until his employment shall be terminated pursuant to
this paragraph. After the completion of either Disability Period provided for in
this paragraph, and Employee continues to be, or is again incapacitated, EMBREX
may, if it so elects, declare Employee's employment terminated on 30 days'
notice given in accordance with the provisions




hereof. Employee shall be considered to be incapacitated when he is
substantially unable to perform the normal duties required of him hereunder on a
continuous daily basis.



7.  EMPLOYEE NOT TO WORK FOR OTHERS

    7.1 During the term of this Agreement, Employee agrees that he will not work
for any other business firm, whether competitive with EMBREX or not, and that
Employee shall devote his full time and attention solely to the business and
interests of EMBREX.

    7.2 Until the second anniversary of the date of termination of the
employment of Employee by EMBREX, Employee agrees that, regardless of the date
or cause of termination of his employment or if it shall be with or without
cause, he will not, directly or indirectly, either as principal, agent, officer,
director, employee, or in any similar capacity, engage in or perform consulting
or any other services for, or have a financial interest in, through sales,
consultant status, manufacture, research or development or similar interest at
the time of termination of Employee's employment, nor will he be, for the same
time period, the owner of record or beneficially of five percent or more of any
class of equity security (or any class of securities convertible to an equity
security), in an entity which so competes with a product of EMBREX.

8.  TECHNIQUES, DISCOVERIES, AND INVENTIONS

    8.1 Employee agrees that any and all sales of manufacturing techniques,
inventions, discoveries or improvements in the products or processes or the
merchandising thereof, of EMBREX, which Employee may create, devise, make,
discover, introduce, or invent while employed by EMBREX shall belong to and be
the sole property of EMBREX. Employee agrees promptly and fully to disclose the
same to EMBREX.

    8.2 It is recognized between EMBREX and Employee that EMBREX has acquired
and developed, and will continue to develop formulae, techniques, plans,
processes, procedures, devices and materials, and lists of customers and their
particular requirements which may pertain to many and varied products and
equipment, which are secret and confidential in character and are, and will
continue to be, of great and unique value to it, which are now and will continue
to be, used in its business (hereinafter referred to as "secret information").
Much of such secret information existing on the date hereof is known to
Employee, by reason of his position, and future secret information on EMBREX
will be disclosed to Employee, as required for proper performance of duties
hereunder and other duties as he may have to EMBREX.

    8.3 Employee agrees that all such secret information heretofore or hereafter
received by him will be kept and maintained by him as confidential and in
complete secrecy, and Employee shall not disclose at any time, either orally or
in writing, or otherwise, in any manner, directly or indirectly, any knowledge
or information Employee has acquired or any trade secret relating to EMBREX or
its subsidiaries, with the exception of disclosure of such information: (i) to
employees of EMBREX who have a need to know it to properly carry out their
duties on behalf of EMBREX and (ii) in the ordinary course of EMBREX business to
customers, suppliers, subcontractors and parties similarly situated.

    8.4 Employee agrees that, while an employee of EMBREX and for two years
thereafter, at least fifteen days before release of publication of any
scientific paper or contributions to periodicals dealing with or making
reference to a subject of interest to EMBREX, Employee will make available to
EMBREX a copy of what is to be published.

9.  DELIVERY OF DATA

    Employee agrees to deliver to EMBREX promptly at the termination of his
employment or at any other time EMBREX may request, all memoranda, notes,
records, sketches, plans, or other documents which are in Employee's possession
or under his control concerning costs, uses, application or purchases of
products made for or by EMBREX (or any subsidiary, affiliate, or licensee of
EMBREX) or any product, process, formula, or manufacturing method used,
developed, produced, or investigated by EMBREX (or any subsidiary, affiliate or
licensee of EMBREX), during his employment hereunder.




10. INJUNCTIVE RELIEF

    Employee agrees that the remedy at law for any breach of the provisions of
paragraphs 7, 8, and/or 9 of this Agreement will be inadequate and that EMBREX
shall be entitled to injunctive relief in addition to any other remedy they
might have as so ordered by a Court.

11. SEVERABILITY

    The provisions of paragraphs 7, 8, 9, and 10 are severable, and in the event
any portion or portions thereof are held to be invalid, such invalidity shall
not affect the validity of the remaining portion or portions.

12. SEVERANCE

    If EMBREX shall terminate the employment of Employee without cause, except
pursuant to 6.1 hereof, or because of death, then Employee shall be liable to
Employee for salary payable pursuant to 4.1 for one month. No sums shall be due
pursuant to any other portion of 4 in the event of termination. The parties
agree that this sum is a reasonable approximation of the actual damages which
they presently anticipate would result from a termination of Employee's
employment, and further agree that this clause is inserted herein not as a
penalty but for the sole purpose of avoiding the difficulty of proof of the
actual damages.

13. NOTICES

    All notices, requests, demands, and other communication hereunder shall be
in writing and shall be deemed to have been duly given if mailed by certified or
registered mail, return receipt requested, to the respective parties at their
addresses appearing above or their last known addresses.

14. ASSIGNMENT

    The Agreement shall not be assignable by either party except pursuant to a
merger, consolidation or other reorganization of EMBREX.

15. SUCCESSORS IN INTEREST

    This Agreement shall be binding on the parties hereto, their heirs,
executors, administrators, successors (whether by merger, consolidation, or
otherwise), and assigns. The parties hereby agree for themselves, their heirs,
executors, administrators, successors, and assigns, to execute any instruments
and to perform any acts which may be necessary or proper to carry out the
purposes of the Agreement, but the failure to execute such instruments will not
affect the rights of any party hereto or the obligations of any estate, as
provided in this Agreement.

16. LAW OF THE AGREEMENT

    This Agreement shall be subject to and governed by the laws of the State of
North Carolina. The provisions of this Agreement are severable, and in the event
any portion or portions hereof are held to be invalid, such invalidity shall not
affect the validity of the remaining portion or portions. If any court or other
competent authority shall hold a portion of this Agreement invalid, unless
modified in a manner described by the court or competent authority, that portion
shall be deemed modified accordingly.
