10. TERMINATION OF EMPLOYMENT

  A.   Termination Events. Notwithstanding any provisions of this Agreement to
the contrary, Employee’s employment may be terminated by Employer with “Cause”
(as hereinafter defined) effective upon the delivery of written notice to
Employee. In addition, Employee’s employment shall terminate (i) upon Employee’s
death or (ii) upon Employee becoming “Disabled” (as hereinafter defined).

  B.   Definition of Disabled. For purposes of this Agreement, Employee shall be
deemed to be “Disabled” when, by reason of physical or mental illness or of
injury, he is unable to perform substantially all of the duties and
responsibilities required of him in connection with his employment hereunder. No
disability shall be deemed to exist until after Employee shall be unable to
perform his duties hereunder for ninety (90) consecutive days (the “Disability
Period”). If Employee shall have been under a disability but shall have returned
to work prior to the end of the Disability Period, any new disability commencing
within 30 days of the termination of the prior disability shall be a
continuation of the prior disability, and the period of all such disabilities
shall be added together to determine whether, or how much of, the Disability
Period has elapsed.

  C.   Definition of Cause. For purposes of this Agreement, “Cause” shall be:
(a) conviction for fraud or felonious criminal conduct, from which no appeal can
be taken; (b) habitual drunkenness or drug addiction; (c) material sanctions
against Employee, imposed or consented to, in his capacity as an employee of
Employer or previous employers by regulatory agencies governing Employer or
against Employer because of wrongful acts or conduct of Employee which have a
material adverse affect upon the Employer and its business; (d) material breach
or default by Employee of any of the material terms or conditions of this
Agreement, and the continuation of such material breach or default by Employee
for a period of seven days following the date of receipt of written notice from
Employer specifying the breach or default of Employee; or (e) the resignation or
quitting of Employee prior to the end of the Employment Term, if applicable, (in
this last event, Employee’s employment shall be deemed terminated with Cause on
the date that he resigns or quits).

      If Employee’s employment is terminated by Employer without cause, as
defined in this section, Employee shall be given 60 days written notice of
termination by Employer, and be entitled to receive one year’s compensation and
fringe benefits/expenses as provided for hereinabove. Additionally, in the event
of termination without cause, or non-renewal of this Agreement at the end of the
Employment Term, any vested but unexercised stock options granted to Employee
shall continue to be fully exercisable through the expiration of 90 days from
the date of termination.

--------------------------------------------------------------------------------

 

  D.   Termination Following a Change of Control.

  i.   In the event that a “Change of Control” as hereinafter defined, and the
occurrence of a “Good Reason” as hereinafter defined, of the Company shall occur
at any time during the Employment Term or extensions thereof, the Employee shall
have the right to terminate the Employee’s employment under this Agreement upon
30 days written notice given at any time within one year after the occurrence of
such events, and such termination of the Employee’s employment with the Company
pursuant to this Subsection 10, then, the Employee shall be entitled to such
Compensation and Benefits as set forth in Subsection 10C of this Agreement.

  ii.   For purposes of this Agreement, a “Change of Control” of the Company
shall mean a change in control (A) as set forth in Section 280G of the Internal
Revenue Code or (B) of a nature that would be required to be reported in
response to Item 1 of the current report on Form 8K, as in effect on the date
hereof, pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934
(the “Exchange Act”); provided that, without limitation, such a change in
control shall be deemed to have occurred at such time as:

  (a)   any person (as such term is used in Section 13(d) and 14(d) of the
Exchange Act) is or becomes the “beneficial owner” (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of securities of the Company
representing fifty percent (50%) or more of the combined voting power of the
Company’s outstanding securities then having the right to vote at elections of
directors; or,

  (b)   the individuals who at the commencement date of this Agreement the Board
of Directors cease for any reason to constitute a majority thereof unless the
election, or nomination for election, of each new director was approved by a
vote of at least two thirds of the directors then in office who were directors
at the commencement of this Agreement; or

  (c)   there is a failure to elect five or more (or such number of directors as
would constitute a majority of the Board of Directors) candidates nominated by
management of the Company to the Board of Directors; or

  (d)   the business of the Company for which the Employee’s services are
principally performed is disposed of by the Company pursuant to a partial or
complete liquidation of the Company, a sale of assets (including stock of a
subsidiary of the Company) or otherwise.

Anything herein to the contrary notwithstanding, this Subsection 10 will not
apply where the Employee gives the Employee’s explicit written waiver stating
that for the purposes of this Subsection 10 a Change in Control shall not be
deemed to have occurred. The Employee’s participation in any negotiations or
other matters in relation to a Change in Control shall in no way constitute such
a waiver which can only be given by an explicit written waiver as provided in
the preceding sentence.

Anything to the contrary notwithstanding, termination shall not be deemed
termination without Cause if there shall not have also occurred at or around a
change in control a second event.

5

--------------------------------------------------------------------------------

 

The second event is that the Employee is given “Good Reason” for choosing to
terminate. Good Reason means, without the Employee’s express written consent,
the occurrence of any of the following events after a Change in Control:

  A.   a reduction by the Employer of the Employee’s rate of annual
compensation,

  B.   the failure of the Employer to continue in effect any Employee benefit
plan or compensation plan in which the Employee participating following the
Change in Control, unless the Employee is permitted to participate in other
plans providing substantially comparable benefits, or the taking of any action
by the Employer which would adversely affect the Employee’s participation in or
materially reduce benefits under any such plan, provided, however, that changes
affecting the participation or benefits of all similarly situated Employees
shall not be treated as Good Reason hereunder,

  C.   a materially adverse change in the level of the Employee’s employment
responsibilities,

  D.   a relocation of Employers offices such that Employee would be required to
relocate his primary residence to provide for a reasonable daily travel distance
to such new location.

11. NON-DISCLOSURE OF CONFIDENTIAL INFORMATION

     Confidential Information. Employee acknowledges that Employee has been
informed that it is the policy of Employer to maintain as secret and
confidential all information relating to (i) the financial condition, businesses
and interests of Employer and its affiliates, (ii) the systems, know-how,
products, services, costs, inventions, patents, patent applications, formulae,
research and development procedures, notes and results, computer software
programs, marketing and sales techniques and/or programs, methods,
methodologies, manuals, lists and other trade secrets heretofore or hereafter
acquired, sold, developed and/or used by Employer and its affiliates and (iii)
the nature and terms of Employer’s and its affiliates’ relationships with their
respective customers, clients, suppliers, lenders, vendors, consultants,
independent contractors and employees (all such information being hereinafter
collectively referred to as “Confidential Information”), and Employee further
acknowledges that such Confidential Information is of great value to Employer
and its affiliates and, in and by reason and as a result of Employee’s
employment by Employer, Employee will be making use of, acquiring and/or adding
to such Confidential Information. Therefore, Employee understands that it is
reasonably necessary to protect Employer’s and its affiliates’ trade secrets,
goodwill and business interests that Employee agree and, accordingly, Employee
does hereby agree, that Employee will not directly or indirectly (except where
authorized by the Board of Employer for the benefit of Employer and/or its
affiliate(s) and/or as required in the course of his employment) at any time
hereafter divulge or disclose for any purpose whatsoever to any persons, firms,
corporations or other entities other than Employer or its affiliates
(hereinafter referred to collectively as “Third Parties”), or use or cause or
authorize any Third Parties to use, any such Confidential Information, except as
otherwise required by law. Notwithstanding the foregoing, “Confidential
Information” shall not include information or data that was (a) known to
Employee on the Effective Date or subsequently disclosed to Employee by a Third
Party having the right to do so, or (b) generally known or available to the
public as of the Effective Date or which subsequently entered the public domain
other than by virtue of disclosure by Employee.

6

--------------------------------------------------------------------------------

 

     Employer’s Materials. In accordance with the foregoing, Employee
furthermore agrees that (i) Employee will at no time retain or remove from the
premises of Employer or its affiliates any research and development materials,
drawings, notebooks, notes, reports, formulae, software programs or discs or
other containers of software, manuals, data, books, records, materials or
documents of any kind or description for any purpose unconnected with the strict
performance of Employee’s duties with Employer and (ii) upon the cessation or
termination of Employee’s employment with Employer for any reason, Employee
shall forthwith deliver or cause to be delivered up to Employer any and all
research and development materials, drawings, notebooks, notes, reports,
formulae, software programs or discs or other containers of software, manuals,
data, books, records, materials and other documents and materials in Employee’s
possession or under Employee’s control relating to any Confidential Information
or any property or information which is otherwise the property of Employer or
its affiliates.

12. COVENANT-NOT-TO-COMPETE

     In view of the Confidential Information to be obtained by or disclosed to
Employee, because of the know-how acquired and to be acquired by Employee
relative to the operations disclosed below, and as a material inducement to
Employer to enter into this Agreement and continue to employ Employee, Employee
covenants and agrees that, so long as Employee is employed by Employer and for a
period of one (1) year after Employee ceases to be employed by Employer as the
result of a termination for any reason as provided in Paragraph 10C hereof or as
a result of Employee not renewing pursuant to Paragraph 2. Employee hereby
agrees to refrain from, anywhere in the world (the “Geographical Area”),
directly or indirectly owning, managing, operating, controlling or financing, or
participating in the ownership, management, control or financing of, or being
connected with or having an interest in, or otherwise taking any part as a
stockholder (other than deminimus amounts as a passive investor), director,
officer, employee, agent, consultant, partner or otherwise in any business
engaged in human leukocyte interferon therapy or avian transgenics.

13. EMPLOYER’S REMEDIES FOR BREACH OF SECTIONS 11 OR 12

Employee covenants and agrees that if Employee shall violate or breach any of
Employee’s covenants or agreements provided for in Sections 11 and/or 12 hereof,
Employer and/or its affiliates shall be entitled to an accounting and repayment
of all profits, compensation, commissions, remuneration or benefits, which
Employee directly or indirectly has realized or realizes as a result of, growing
out of or in connection with any such violation or breach. In addition, in the
event of a breach or violation or threatened or imminent breach or violation of
any provisions of Sections 11 and/or 12 hereof, Employer and/or its affiliates
shall be entitled to a temporary and permanent injunction or any other
appropriate decree of specific performance or equitable relief, without posting
of bond, from a court of competent jurisdiction in order to prevent, prohibit or
restrain any such breach or violation or threatened or imminent breach or
violation by Employee, by Employee’s partners, agents, representatives,
servants, employers or employees. Employer shall be entitled to such injunctive
or other equitable relief in addition to any damages which are suffered, and the
prevailing party shall be entitled to reasonable attorneys’ and paralegals’ fees
and costs and other costs incurred in connection with any such litigation, both
before and at trial and at all tribunal levels. Resort by Employer and/or its
affiliates to such injunctive or other equitable relief shall not be deemed to
waive or to limit in any respect any other rights or remedies which Employer or
its affiliates may have with respect to such breach or violation.

7

--------------------------------------------------------------------------------

 

The provisions of this Employment Agreement shall not prevail over any
applicable law, regulation or restriction that may apply to the conduct of the
Company’s business and neither party is compelled to adhere to this Agreement
if, in so doing, a violation of law, regulation or restriction would result. In
the event Employee chooses to terminate his employment as a result of an
unremedied violation of such law or regulation, Employer’s remedies pursuant to
this paragraph 13 would not be applicable.

14. REASONABLENESS OF RESTRICTIONS

  A.   Reasonableness. Employee acknowledges that any material breach or
violation of Sections 11 and/or 12 hereof will cause irreparable injury and
damage and incalculable harm to Employer and its affiliates and that it would be
very difficult or impossible to measure the damages resulting from any such
breach or violation. Employee further acknowledges that Employee has carefully
read and considered the provisions of Sections 11 and 12 hereof and, having done
so, agrees that the restrictions and remedies set forth in such Sections
(including, but not limited to, the time period, geographical and types of
restrictions imposed) are fair and reasonable and are reasonably required for
the protection of the business, trade secrets, interests and goodwill of
Employer and its affiliates.

  B.   Severability. Employee understands and intends that each provision and
restriction agreed to by Employee in Sections 12 and 13 hereof shall be
construed as separate and divisible from every other provision and restriction
and that, in the event that any one of the provisions of, or restrictions in,
Sections 12 and/or 13 hereof shall be held to be invalid or unenforceable, the
remaining provisions thereof and restrictions therein shall nevertheless
continue to be valid and enforceable as though the invalid or unenforceable
provisions or restrictions had not been included therein, and any one or more of
such valid provisions and restrictions may be enforced in whole or in part as
the circumstances warrant. In the event that any such provision relating to time
period and/or geographical and/or type of restriction shall be declared by a
court of competent jurisdiction to exceed the maximum or permissible time
period, geographical area or type of restriction such court deems reasonable and
enforceable, said time period and/or geographical and/or type of restriction
shall be deemed to become and shall thereafter be the maximum time period and/or
geographical restriction and/or type of restriction which such court deems
reasonable and enforceable.

  C.   Survivability. The restrictions, acknowledgments, covenants and
agreements of Employee set forth in Sections 11, 12, and 13 of this Agreement
shall survive any termination of this Agreement or of Employee’s employment (for
any reason, including expiration of the Employment Term, including extensions
thereof, if applicable).

  D.   Comparable Restrictions. Employer agrees that it will use its best
efforts to have other senior executives execute and observe agreements
containing similar provisions as are contained in Sections 11, 12, 13 and 14
hereof.

8

--------------------------------------------------------------------------------

 

15. EMPLOYEE’S DISCLOSURES AND REPRESENTATIONS AND WARRANTIES.

Employee hereby acknowledges, represents and warrants to, and/or agrees with,
Employer as follows:

  (a)   Subject to Employee’s right to designate family members to own the stock
acquired through exercise of the Options, if any, that Employee is acquiring the
Options for his own account, for investment purposes only, and not with a view
to the public sale or distribution thereof, except as applicable under any Form
S-8 Registration filed by the Company covering the Shares underlying the
Options.

  (b)   That Employee has full right, power and authority to perform all
obligations under this Agreement.

  (c)   Employee hereby agrees to indemnify and hold harmless Employer and its
shareholders, directors, officers, employees and agents from and against any and
all loss, damage, liability, cost or expense (including reasonable attorneys’
and paralegals’ fees and costs before and at trial and at all appellate levels)
due to or arising out of any material inaccuracy in, or material breach of, any
material representation, warranty or covenant of Employee contained herein.

16. INDEPENDENT COUNSEL

Employer and Employee agree that each of them have been, or were advised and
fully understand that they are entitled to be represented by independent legal
counsel with respect to all matters contemplated herein from the commencement of
negotiations at all times through the execution hereof.

17. LAW APPLICABLE

This Agreement shall be governed by and construed pursuant to the laws of the
State of Florida, without giving effect to conflicts of laws principles.

18. ARBITRATION

Any dispute, controversy, or claim arising out of or in connection with this
Agreement, including any questions regarding its existence, validity or
termination, shall be finally resolved by arbitration by the American
Arbitration Association or JAMS/Endispute except as otherwise provided
hereafter. Any such dispute, controversy or claim shall be submitted to a board
of arbitrators composed of three competent disinterested persons, one to be
chosen by Employer, one by Employee and the third to be selected by the two
arbitrators so chosen. Such arbitration shall be conducted in English and all
hearings in connection with such arbitration will take place in Broward County,
Florida. The prevailing party shall be entitled to reimbursement of any and all
fees of the arbitration proceedings.

The arbitrators may not award non-monetary or equitable relief of any sort. They
shall have no power to award punitive damages or any other damages not measured
by the prevailing party’s actual damages, and the parties expressly waive their
right to obtain such damages in arbitration or in any other forum. In no event,
even if any other portion of these provisions is held to be invalid or
unenforceable, shall the arbitrators have power to make an award or impose a
remedy that could not be made or imposed by a court deciding the matter in the
same jurisdiction.

No discovery will be permitted in connection with the arbitration unless it is
expressly authorized by the arbitration panel upon a showing of substantial need
by the party seeking discovery.

9

--------------------------------------------------------------------------------

 

All aspects of the arbitration shall be treated as confidential. Neither the
parties nor the arbitrators may disclose the existence, content or results of
the arbitration, except as necessary to comply with legal or regulatory
requirements. Before making any such disclosure, a party shall give written
notice to all other parties and shall afford such parties a reasonable
opportunity to protect their interests.

The result of the arbitration will be binding on the parties, and judgement on
the arbitrators’ award may be entered in any court having jurisdiction.

19. NOTICES

Any notices required or permitted to be given pursuant to this Agreement shall
be sufficient, if in writing, and if personally delivered or sent by certified
or registered mail, return receipt requested, to his residence, in the case of
Employee, or to its then principal office, in the case of Employer.

Employer agrees to notify Employee, by certified mail, 120 days prior to March
28, 2007 and each March 28th anniversary as further described in Paragraph 2 of
this Agreement.

20. SUCCESSION

This Agreement shall inure to the benefit of and be binding upon the parties
hereto and their respective legal representatives, heirs, assignees and/or
successors in interest of any kind whatsoever; provided, however, that Employee
acknowledges and agrees that he cannot assign or delegate any of his rights,
duties, responsibilities or obligations hereunder to any other person or entity.

21. ENTIRE AGREEMENT

This Agreement constitutes the entire final agreement between the parties with
respect to, and supersedes any and all prior agreements, both oral and written,
between the parties hereto, except as related to rights of the Employee and
obligations related thereto of Employer regarding previously granted stock
options and previously purchased stock, as may have been modified from time to
time. The subject matter hereof may not be amended, modified or terminated
except by a writing signed by the parties hereto.

22. SEVERABILITY

If any provision of this Agreement shall be held to be invalid or unenforceable,
and is not reformed by a court of competent jurisdiction, such invalidity or
unenforceability shall attach only to such provision and shall not in any way
affect or render invalid or unenforceable any other provision of this Agreement,
and this Agreement shall be carried out as if such invalid or unenforceable
provision were not contained herein.

23. NO WAIVER

A waiver of any breach or violation of any term, provision or covenant contained
herein shall not be deemed a continuing waiver or a waiver of any future or past
breach or violation. No oral waiver shall be binding.

10

--------------------------------------------------------------------------------

 

24. ATTORNEY’S FEES

In the event that either of the parties to this Agreement institutes suit
against the other party to this Agreement to enforce any of his or its rights
hereunder, the prevailing party in such action shall be entitled to recover from
the other party all reasonable costs thereof, including reasonable attorneys’
and paralegals’ fees and costs incurred before and at trial and at all tribunal
levels.

25. COUNTERPARTS

This Agreement may be executed in counterparts, each of which shall be an
original, but both of which together shall constitute one and the same
instrument.

26. INDEMNITY OF EMPLOYEE

Employer shall indemnify and hold harmless Employee from and against any and all
claims, judgements, fines, penalties, liabilities, losses, costs and expenses
(including reasonable attorneys’ fees and costs) asserted against or incurred by
Employee as a result of acts or omissions of Employee taken or made in the
course of performing his duties for Employer or by reason of Employee acting or
having acted as a director or officer of Employer, to the maximum extent
permitted by law, including Section 607.0850, Florida Statutes (including the
advancement of expense provisions thereof); provided, however, that such
indemnity shall not apply to acts or omissions of Employee which constitute
misconduct, gross negligence or which were intended by Employee to personally
benefit Employee, directly or indirectly, at the expense of Employer, unless the
matter which benefits Employee was first fully disclosed to the Board of
Directors of Employer and approved by said Board.

Employer further agrees to use its best efforts to maintain Directors and
Officers insurance coverage, for a minimum of $10 million, during the Employment

issued and outstanding shares of the Common Stock through the declaration of a
stock dividend or through any recapitalization resulting in a stock split-up,
combination or exchange of the Common Stock, then and in such event:

     (i) appropriate adjustment shall be made in the maximum number of Shares
available for grant, so that the same percentage of the Company’s issued and
outstanding Shares shall continue to be subject to being so optioned; and

     (ii) appropriate adjustment shall be made in the number of Shares, and the
