person,  firm  or  corporation.

to the Confidential Information. Further, the existence of any claim or cause of
action of Director against PharmaFrontiers or any officer, director, or employee
of PharmaFrontiers, whether predicated on this Agreement or otherwise, shall not
constitute  a  defense  to  the  enforcement  by  PharmaFrontiers  of Director's

                                        3

right,  to  an  injunction  without the necessity of posting bond, issued by any
court  of competent jurisdiction, restraining any further or continued breach or
violation  of this covenant. Such right to an injunction shall be cumulative and
in  addition to, and not in lieu of, any other remedies to which PharmaFrontiers
may show itself justly entitled. Further, during any period in which Director is
in  breach  of  this  covenant  not to compete, the time period of this covenant
shall  be  extended  for  an  amount  of  time  that  Director  is  in  breach.

and made prior to the termination of this Agreement (unless the Director clearly
proves that such Development was conceived and made following the termination of
this  Agreement),  and  shall  accordingly  belong,  and  be  assigned,  to
PharmaFrontiers  and  shall  be  subject  to  this  Agreement.

the  Board,  all biological materials correspondence, memoranda, notes, records,
drawings,  sketches,  plans,  customer, client and/or contributor lists, product
compositions,  or  other  documents  and  all  copies  thereof (all of which are
hereafter  referred  to  as  the  "Documents"),  made,  composed  or received by
Director, solely or jointly with others, and which are in Director's possession,
custody,  or  control  at  such  date and which are related in any manner to the
past,  present,  or  anticipated  business  of  PharmaFrontiers.

     3.4 Director further agrees that Director will not, during the term of this
Agreement,  and  on  behalf  of  PharmaFrontiers accept or agree to receive from
persons  not  employed  by  PharmaFrontiers,  any  confidential  information not
belonging to PharmaFrontiers, unless prior to such receipt or acceptance a valid
agreement  has  been  executed  between PharmaFrontiers and the disclosing party
that states that PharmaFrontiers will not be in a confidential relationship with
the  disclosing  party.  Director  further  agrees that Director will not use in
violation  of  any  confidentiality  obligation  binding  upon  Director  any
confidential  information  belonging  to  Director's  employer  or  any  former
employer,  or  any  other  third  parties.

     3.5  In the event of a breach or threatened breach of any of the provisions
of  Section  4,  or  any  breach  by  Director  of  his  fiduciary obligation to
PharmaFrontiers  and  its  shareholders, PharmaFrontiers shall be entitled to an
injunction  ordering the return of such Documents and any and all copies thereof
and restraining Director from using or disclosing, for Director's benefit or the
benefit  of others, in whole or in part, any Confidential Information, including
but  not  limited

<PAGE>
to  the  Confidential  Information  which such Documents contain, constitute, or
embody.  Director  further agrees that any breach or threatened breach of any of
the  provisions  of  Section 4 would cause irreparable injury to PharmaFrontiers
for  which  it  would  have  no  adequate remedy at law. Nothing herein shall be
construed  as  prohibiting  PharmaFrontiers  from  pursuing  any  other remedies
available to it for any such breach or threatened breach, including the recovery
of  damages.

4.   Noncompetition/No-Hire  Agreement

     4.1 Director agrees that, from the Effective Date until a period of one (1)
year following the date of his resignation removal or failure to be nominated or
elected  as  a member of the Board, (the "Noncompetition Period"), Director will
not  directly or indirectly, either as an employee, employer, consultant, agent,
principal,  partner,  corporate officer, director, or in any other individual or
representative  capacity,  engage  or  participate in any "Competitive Business"
anywhere  in  the  United  States  of America, Canada or the European Union (the
"Noncompetition Territory"). As used herein, a "Competitive Business" is defined
as  any business, including those relat'-1g to stem cells or cell banking, which
provides  the  same  or substantially the same products, services or licenses to
intellectual  property  rights,  in  whole  or  in  part,  as  are  provided  by
PharmaFrontiers  during  the  term  of  this  Agreement.

     4.2  Director  further  agrees  that  during  the Noncompetition Period and
within  the  Noncompetition Territory Director will not, directly or indirectly,
either  as  an  employee,  employer,  consultant,  agent,  principal,  partner,
corporate  officer,  director,  or  in  any  other  individual or representative
capacity, call on, solicit, recruit, or attempt to call on, solicit, or recruit,
or  attempt  to  hire  any  of  the  employees of PharmaFrontiers, regardless of
whether  for  the  benefit  of  the  Director  or for any other person, firm, or
corporation.

     4.3  Director  shall  not  during  the Noncompetition Period and within the
Noncompetition  Territory,  either  directly or indirectly (i) make known to any
Competitive  Business  the  names  and  addresses  of  any  of  PharmaFrontiers'
customers  or  contacts  or  any other information pertaining to such persons or
businesses  or  (ii)  call  on,  solicit,  or  take away, or attempt to call on,
solicit  or take away any of the customers of PharmaFrontiers with whom Director
b:ame  acquainted  during  Director's  service  as  a member of PharmaFrontiers'
Board,  regardless  of  whether for the benefit of the Director or for any other
person,  firm  or  corporation.

     4.4  Director  agrees that this Section is ancillary to this Agreement, and
Director  acknowledges  that the consideration given by PharmaFrontiers for this
Agreement  includes PharmaFrontiers' agreement to provide to the Director access
to the Confidential Information. Further, the existence of any claim or cause of
action of Director against PharmaFrontiers or any officer, director, or employee
of PharmaFrontiers, whether predicated on this Agreement or otherwise, shall not
constitute  a  defense  to  the  enforcement  by  PharmaFrontiers  of Director's
covenants  contained  in  this  Agreement.  In  addition,  this  Agreement shall
continue  to  be  binding  upon  Director  in  accordance  with  its  terms,
notwithstanding  the  termination  of  this  Agreement.

     4.5 Director agrees that Director's breach or violation, or threat thereof,
of  this  covenant  not to compete shall entitle PharmaFrontiers, as a matter of
right,  to  an  injunction  without the necessity of posting bond, issued by any
court  of competent jurisdiction, restraining any further or continued breach or
violation  of this covenant. Such right to an injunction shall be cumulative and
in  addition to, and not in lieu of, any other remedies to which PharmaFrontiers
may show

                                        3
<PAGE>
itself  justly  entitled.  Further,  during  any  period in which Director is in
breach  of  this covenant not to compete, the time period of this covenant shall
be  extended  for  an  amount  of  time  that  Director  is  in  breach.

5.   Inventions and Other Intellectual Property

     5.1  Director  agrees  to  hold  in  complete  trust  for  the  benefit  of
PharmaFrontiers,  and  to  disclose  promptly  and  fully  to PharmaFrontiers in
writing,  and  hereby  assigns,  and  binds  Director's  heirs,  executors,
administrators,  and all legal representatives to assign, to PharmaFrontiers any
and  all  inventions,  discoveries, ideas, concepts, improvements, copyrightable
works,  biological  materials,  and  other  developments  (all  of the above are
collectively  referred  to as the "Developments") conceived, made, discovered or
developed  by  him,  solely  or  jointly  with  others,  during the term of this
Agreement,  whether  during  or  outside  of  usual working hours and whether on
PharmaFrontiers'  premises  or  not,  which  relate  in  any manner to the past,
present  or  anticipated business of PharmaFrontiers. The parties agree that, if
Director  is  an  inventor  as  determined by U.S. patent law for any invention,
Director shall be named as an inventor in connection with any patent application
therefor. Any and all such Developments shall be the sole and exclusive property
of  PharmaFrontiers, whether patentable, copyrightable, or neither, and Director
agrees  that  Director  will  assist  and  fully  cooperate  in  every  way,  at
PharmaFrontiers'  expense,  in  securing,  maintaining,  and  enforcing, for the
benefit  of  PharmaFrontiers or its designee, patents, copyrights or other types
of  proprietary or intellectual property protection for such Developments in any
and  all  countries.  Director  acknowledges  and  agrees  that any and all such
Developments  conceived,  created, or authored by him is a "work made for hire,"
as defined by the federal copyright laws, and therefore all copyrights in and to
such works are and will be owned by PharmaFrontiers. To the extent that Director
authors  any  copyrightable work in any medium during the term of this Agreement
which relates or pertains in any way to PharmaFrontiers or any of the operations
or activities of either and which was is held not a work made for hire, Director
hereby  assigns all right, title, and interest, including but not limited to all
rights  of copyright, in and to such works to PharmaFrontiers. Within six months
following the termination of this Agreement, and without limiting the generality
of  the  foregoing,  any  Development  of  the  Director  relating  to  any
PharmaFrontiers  subject  matter on which Director worked or was informed during
the term of this Agreement shall be conclusively presumed to have been conceived
and made prior to the termination of this Agreement (unless the Director clearly
proves that such Development was conceived and made following the termination of
this  Agreement),  and  shall  accordingly  belong,  and  be  assigned,  to
PharmaFrontiers  and  shall  be  subject  to  this  Agreement.

     5.2  Without  limiting  the  foregoing,  Director  agrees at the request of
PharmaFrontiers (but without additional compensation from PharmaFrontiers during
Director's  employment  by  PharmaFrontiers)  to  execute any and all papers and
perform  all  lawful  acts  which  PharmaFrontiers  deems  necessary  for  the
preparation,  filing,  prosecution,  and  maintenance of applications for United
States  and foreign letters patent, or for United States and foreign copyrights,
on  the  Developments,  and  to  execute  such  instruments  as are necessary or
convenient  to  assign  to PharmaFrontiers, its successors, assigns or nominees,
all  of  the  Director's  right, title, and interest in the Developments and the
like,  so  as  to  establish,  maintain  or  perfect,  in  PharmaFrontiers,  its
successors,  assigns  or  nominees, the entire right, title, and interest to the
Developments,  and  also  to  execute  any  instruments  necessary  or  which
PharmaFrontiers  may deem desirable it connection with any continuation, renewal
or reissue thereof, or in the conduct

                                        4
<PAGE>
of  any  proceedings  or  litigation  in  regard  thereto.

     5.3  All  expenses incurred by the Director by reason of the performance of
any of the obligations set forth in this Section on Inventions shall be borne by
PharmaFrontiers.  Should  the  Director's  assistance  be  requested  by
PharmaFrontiers  after  termination  of  this  Agreement,  PharmaFrontiers would
compensate  the  Director  at  a  reasonable  rate.

6.   Conflicts  of  Interest

     6.1  In  keeping  with  Director's  fiduciary  duties  to  PharmaFrontiers,
Director agrees that Director shall not, directly or indirectly, become involved
in any conflict of interest, or upon discovery thereof, allow such a conflict to
continue. Moreover, Director agrees that Director shall promptly disclose to the
Board  of  PharmaFrontiers  any  facts  which  might  involve  any  reasonable
lossibility of a conflict of interest as PharmaFrontiers is currently and in the
future  configured  and practicing business. Director shall maintain the highest
standards  of conduct, and shall not do anything likely to injure the reputation
or  goodwill  of  PharmaFrontiers,  or  embarrass  or otherwise generate adverse
publicity  for  or  bring  unwanted  attention  to  PharmaFrontiers.

     6.2  It is agreed that any direct or indirect interest in, connection with,
or  benefit  from  any  outside  activities, particularly commercial activities,
which  interest  might in any way adversely affect PharmaFrontiers or any of its
subsidiaries  or  affiliates,  involves  a  possible  conflict  of  interest.
Circumstances  in  which a conflict of interest on the part of Director would or
might  arise, and which should be reported immediately by Director to an officer
of PharmaFrontiers, include, without limitation, the following: (a) ownership of
a  material  interest  in,  acting in any capacity for, or accepting directly or
indirectly  any  payments,  services  or  loans  from  a  supplier,  contractor,
subcontractor,  customer  or  other  entity  with  which  PharmaFrontiers  does
business;  (b)  misuse of information or facilities to which Director has access
in  a  manner  which  will  be  detrimental  to  PharmaFrontiers'  interest; (c)
disclosure  or  other  misuse  of  information  of any kind obtained through the
Director's connection with PharmaFrontiers; (d) acquiring r trading in, directly
or  indirectly,  other  properties  or  interests  connected  with  the  design,
manufacture  or  marketing  of  products  designed,  manufactured or marketed by
PharmaFrontiers;  (e)  the  appropriation  to  the  Director or the diversion to
others, directly or indirectly, of any opportunity in which it is known or could
reasonably  be anticipated that PharmaFrontiers would be interested; and (f) the
ownership,  directly  or  indirectly, of a material interest in an enterprise in
competition  with PharmaFrontiers or its dealers and distributors or acting as a
director,  officer,  partner,  consultant,  Director  or agent of any enterprise
which  is  in  competition  with PharmaFrontiers or its dealers or distributors.

7.   Prior Discoveries

     Director  has no unpatented inventions and discoveries made or conceived by
Director  prior  to  the  Effective  Date  that  relate  to stem cell isolation,
identification  and/or  expansion  and/or  cell  banking.

8.   Remedies

     Director  and  PharmaFrontiers  agree  that, because damages at law for any
breach  or  nonperformance of this Agreement by Director, while recoverable, are
and  will  be  inadequate,  this Agreement may be enforced in equity by specific
performance,  injunction,  accounting or

<PAGE>
otherwise.
