Exhibit 10.4


                              EMPLOYMENT AGREEMENT

     THIS AGREEMENT  ("Agreement") made and entered into this 23rd day of March,
1999, by and between APPLIED CELLULAR  TECHNOLOGY,  INC., a Missouri corporation
("Company") and RICHARD J. SULLIVAN ("Employee").

                                   BACKGROUND

     Employee  has been and  presently is employed by Company as its chairman of
the board and chief  executive  officer.  The parties have entered into a formal
employment  agreement  covering  the terms and  conditions  of such  employment.
Subsequently,  the parties reached a tentative agreement regarding some, but not
all, of the terms and conditions of a revised employment agreement.  The parties
have now reached an  agreement on all of the terms and  conditions  of a revised
employment  agreement  and desire to set forth in this  document  such terms and
conditions.

                              TERMS AND CONDITIONS

     1. Employment. Company hereby employs Employee, and Employee hereby accepts
such  employment by Company,  on the terms and  conditions  set forth below.  

     2. Capacity.  Employee  shall serve as Company's  chairman of the board and
chief  executive  officer.  Employee shall perform such services for company and
its  subsidiaries  and affiliates as Company's  board of directors  shall direct
from time to time.  However, no such services shall be of a nature which are not
commensurate with, and/or are beneath the dignity of, Employee's title. 




     3. Term. Company's employment of Employee under this Agreement shall be for
an initial term of five years  commencing on July 1, 1998 and ending on June 30,
2003. The term of Employee's employment under this Agreement shall automatically
be renewed for successive  additional one year terms on each  anniversary of the
commencement of Employee's  employment under this Agreement,  beginning with the
July 1, 1999 anniversary  date, each of which terms shall be added at the end of
the then existing term (taking into account any prior  extensions or failures to
extend),  unless  either  party  notifies the other at least 30 days prior to an
anniversary  date of this Agreement.  For example,  unless either party notifies
the other to the contrary on or before June 1, 1999,  the term of this Agreement
shall be extended from July 1, 2003 to June 30, 2004. For further  example,  and
assuming the term of this  Agreement  has been extended to June 30, 2004, if one
party  notifies  the other  that it does not  desire to extend  the term of this
Agreement for an  additional  year and such notice is given on or before June 1,
2000, the term of this Agreement shall not be extended from July 1, 2004 to June
30, 2005.  Notwithstanding  the  foregoing,  the term of this  Agreement may end
prior to the termination  date determined  under this paragraph 3 as provided in
paragraphs 9, 10, 11 and 12.

     4. Service While Employed.  Employee agrees to devote his best efforts, his
full  diligence and at least 60% his business  time to his duties  hereunder and
shall not  engage,  either  directly  or  indirectly,  in any  business or other
activity which is  competitive  with or adverse to the interests or the business
of Company.

     5. Items Furnished and Relocation. Company shall furnish Employee with such
private office, secretarial assistance, and such other facilities, equipment and


                                       2


services  suitable to his position and adequate to perform his duties hereunder.
Employee shall not be relocated by Company without his consent.

     6. Compensation,  Vacations and Reimbursement.  As partial compensation for
his  services to Company,  Company  agrees to pay  Employee an annual  salary in
regular monthly or other agreed upon  installments of not less than $450,000 and
an annual  bonus of not less  than  $140,000.  In  addition,  Employee  shall be
entitled  to receive  such  bonuses  (in  addition  to that  required  under the
preceding sentence),  incentive compensation, and other compensation, if any, as
Company's board of directors,  executive committee,  compensation  committee, or
other  designated  committee  shall award  Employee from time to time whether in
cash, Company stock, stock options,  other stock based compensation,  other form
of  remuneration,  or any  combination of the foregoing.  All such  compensation
shall be subject to legally  required  income and  employment  tax  withholding.
Employee  shall  be  entitled  to  paid  vacations  and  reimbursement  for  all
reasonable business expenses in accordance with Company's policies for executive
officers.

     7. Other Benefits. In addition to his compensation described in paragraph 6
above,  Employee shall be entitled to participate in such bonus, profit sharing,
deferred compensation and pension plans of Company for which he is eligible.

     8. Welfare and Fringe Benefits.  In addition to his compensation  described
in paragraph 6 and the benefits  described in paragraph 7 above,  Employee shall
be  entitled  to  participate  in such  welfare  and fringe  benefits  plans and
programs of the Company for which he is eligible.


                                       3



     9.  Death  and  Disability.  If  Employee  dies  during  the  term  of this
Agreement, his employment shall be deemed to have been terminated as of the last
day of the month in which his death  occurs,  and Company will pay to Employee's
personal  representative  all salary and other compensation due Employee through
the end of such  month.  If  Employee  becomes  permanently  disabled so that he
cannot perform his duties hereunder, as determined by a physician selected by or
acceptable to Company, his employment shall be deemed to have been terminated as
of the last day of the month in which such  determination  is made,  and he will
receive his salary and other  compensation  through  the end of such month.  For
purposes of the foregoing computations,  Employee shall be deemed to have earned
the same  percentage of his minimum annual bonus for such employment year as the
number of days in the employment  year through the date his employment is deemed
to terminate is of 365.

     10.  Retirement.  From and after the time  Employee  attains age 65, he may
retire  at any  time by  notifying  Company  at  least  120  days  prior  to his
retirement date or be retired by Company upon at least two years notice.

     11.  Default.  In the event that  either  party  fails to perform  material
provision  of this  Agreement  and  such  failure  continues  for 15 days  after
notification from the nonbreaching  party, the nonbreaching  party may terminate
this  Agreement by notice to the  breaching  party.  Such  termination  shall be
without  prejudice to any rights or remedies  which the  nonbreaching  party may
have.

     12.  Change  in  Control.  Notwithstanding  any  other  provision  of  this
Agreement,  should a "change of control" occur, Employee, at his sole option and
discretion, may terminate his employment under this Agreement at any time within


                                       4


one year after such change of control upon 15 days notice.  In the event of such
termination,  Company  shall pay to  Employee a  severance  payment  ("Severance
Payment") equal to three times the base amount as defined in Section  280G(b)(3)
of the  Internal  Revenue  Code  of  1986,  as  amended  ("Code")  minus  $1.00.
Notwithstanding  the  foregoing,  (a) if the  Severance  Payment  and any  other
amounts payable by Company to Employee are parachute payments under Code Section
280b  (collectively,  "Parachute  Payments") and, (b), if reducing the Severance
Payment would eliminate the tax provided for in Code Section 4999 ("Section 4999
Tax") which would otherwise be applicable to the Parachute Payments, and (c) if,
because of such  elimination,  the net amount of the Parachute  Payments  (total
payments  minus Section 4999 Tax) would be greater than such net amount  without
reduction,  then the Severance  Payment shall be reduced by the smallest  amount
required to eliminate  the  imposition  of the Section  4999 Tax. The  foregoing
determination shall be made by Company's general counsel,  and his determination
shall be binding  upon Company and  Employee.  The amount  determined  under the
foregoing  provisions  of this  paragraph  12 shall be payable no later than one
month after the effective  date of the Employee's  termination of employment.  A
change in control  means:  the  acquisition,  without the  approval of Company's
board of  directors,  by any person or entity,  other than Company or a "related
entity," of more than 20% of the outstanding  shares of Company's  voting common
stock through a tender offer,  exchange offer or otherwise;  the  liquidation or
dissolution  of  Company  following  a  sale  or  other  disposition  of  all or
substantially  all of its assets;  a merger of consolidation  involving  Company
which results in Company not being the surviving parent corporation; or any time
during any two-year  period in which  individuals  who  constituted the board of
directors of Company at the start of such period (or whose election was approved
by at least  two-third  of the then members of the board of directors of Company
who were members at the start of the two-year period) do not constitute at least

                                    5


50% of the board of directors for any reason.  A related entity is the parent, a
subsidiary  or any employee  benefit plan  (including a trust  forming a part of
such a plan) maintained by Company, its parent or a subsidiary.

     13.  Nondisclosure;  Return  of  Records.  Employee  will  not,  except  as
authorized  by  Company,  publish  or  disclose  to  others,  or use for his own
benefit, or authorize anyone else to publish or disclose or use, or copy or make
notes of any secret,  proprietary,  or confidential  information or knowledge of
data or trade secrets of or relating to the business activities of Company which
may come to Employee's  knowledge  during his employment with the Company.  Upon
termination of Employee's  employment  for any reason,  Employee will deliver to
Company,  without retaining any copies, notes or excerpts,  all records,  notes,
data,  memoranda,  and all other  documents  or  materials  made or  compiled by
Employee,  or made available to him by Company during his employment,  which are
in Employee's  possession  and/or  control and which are the property of Company
and/or which relate to  Employee's  employment  or the  business  activities  of
Company.

     14. Binding  Effect.  This Agreement shall be binding upon and inure to the
benefit of Company and any successors or assigns of Company,  and Employee,  his
heirs, personal  representatives and assigns, except that Employee's obligations
to  perform   services  and  rights  to  receive  payment   therefore  shall  be
nonassignable and nontransferable.

     15. Entire Agreement:  Modification.  This Agreement constitutes the entire
agreement  between the parties with respect to the subject matter and supersedes

                                       6


all prior or  contemporaneous  agreements not set forth in this agreement.  This
Agreement  may not be modified  other than by an agreement in writing  signed by
each of the parties.

     16.  Waiver.  Any failure by either party to enforce any  provision of this
Agreement  shall  not  operate  as a  waiver  of  such  provision  or any  other
provision.  Any waiver by either  party of any breach of any  provision  of this
Agreement shall not operate as a waiver of any other breach of such provision or
any other provision of this agreement.

     17.  Severability.  The  invalidity or  unenforceability  of any particular
provision  of this  Agreement  shall not  effect  the other  provisions  of this
Agreement,  and this  Agreement  shall be  construed  in all respects as if such
invalid or unenforceable provision were omitted.

     18. Paragraph  Headings.  Paragraph headings  throughout this Agreement are
solely for the  convenience  of the parties and shall not be construed as a part
of any section or as modifying the contents of any section.

     19.  Governing  Law.  This  Agreement  shall be governed  and  construed in
accordance with the laws of the State of Missouri.

     20.  Notices.   All  notices  under  this  Agreement  shall  be  personally
delivered,  sent certified mail,  postage  prepaid,  to Company at its corporate
office and to Employee at his principal residence, or sent by telecopy.

     21.   Supplemental   Compensation.   Upon  the  termination  of  Employee's
employment  with  Company  for any  reason,  other  than due to his  breach of a
material  provision of his  employment  as described in paragraph  11,  Employee
shall be entitled to receive from Company 60 equal  monthly  payments,  with the
first such payment due on the second first day of the month after termination of
employment,  of $37,500 each.  If Employee  should die before all or any part of


                                       7


the above  described  monthly  payments  have been  made,  all  payments  or all
remaining  payments  shall  be  made  to his  designated  beneficiary,  if  any,
otherwise to his estate.  Notwithstanding  the foregoing,  the aggregate  amount
payable under this paragraph 21 shall be reduced by the amount,  if any, payable
under paragraph 12.

     22. Non-Competition. During the period that Employee is entitled to receive
payments under paragraph 21, Employee shall not engage,  directly or indirectly,
either on his own behalf or on behalf of any other person, firm,  corporation or
other entity, in any business  competitive with the business of Company,  in the
geographic  area  in  which  Company  is  conducting  business  at the  time  of
termination  of  Employee's  employment,  or own more than 5% of any such  firm,
corporation  or other entity.  In addition,  Employee must furnish  Company with
such  information  as  Company  shall  from  time to time  request  in  order to
determine that Employee is in compliance with the  requirements of the preceding
provisions of this paragraph 22. The payments to be made under  paragraph 21 are
conditioned upon Employee's  complying with the provisions of this paragraph 22,
and,  in the event that such  provisions  are not  complied  with,  Company  may
suspend  such  payments  for any  period  of time in  which  Employee  is not in
compliance with the preceding provisions of this paragraph 22.

     23.  Company.  For purposes of paragraphs 4, 13, and 22 of this  Agreement,
the Company shall mean Applied  Cellular  Technology,  Inc. and all subsidiaries
and affiliates of it.

     24.  Salary  in Stock or Cash.  At least 10 days  prior to each July 1 that
this Agreement is in effect,  Employee shall elect the amount or percentage,  if
any,  of his  salary  for the 12 month  period  beginning  on that date which he
desires to be payable in company common stock ("Stock").  To the extent Employee

                                       8


elects to have all or part of his salary  paid in Stock,  the per share value of
the Stock, which shall be used to determine the number of shares payable for the
employment  year,  shall be the average closing price for the last five business
days prior to the  applicable  July 1. Any  election  shall be  irrevocable.  If
Employee fails to make a timely  election,  his entire salary for the employment
year shall be paid in cash.  Any shares of Stock  payable to  Employee  shall be
subject to such transfer  restrictions as are required by applicable  securities
law and a legend to such effect  shall be placed on the  certificates.  Employee
represents  and  warrants  that any Stock which will be paid to him  pursuant to
this paragraph 24 shall be acquired for  investment  purposes and not for resale
or distribution. Company shall include such Stock in any subsequent registration
to the extent  practical.  If any portion of Employee's salary is paid in Stock,
Employee  shall tender to Company the amount  required for income and employment
tax withholding on any such payment. If, and to the extent such amount is not so
tendered, Company may withhold the number of shares of Stock equal to the amount
such  required  withholding  from  the  shares  of  Stock  issued  to  Employee.
Notwithstanding the foregoing  provisions of this paragraph 24, unless otherwise
elected by Employee on or before August 21, 1998, the election  previously  made
under the prior  employment  agreement for the employment year beginning June 1,
1998 shall apply to the  employment  year  beginning  on July 1, 1998.  Any such
revised  election shall apply only to salary payable after such revised election
is made.

     25. Other Matters.  For purposes of this paragraph 25, the following  words
shall have the following respective meanings:

          (a) Condominium.  The condominium  owned by Company known and numbered
     as Unit #14, 6110 North Ocean Boulevard, Pelican Cove, Ocean Ridge, Florida
     33480, or any condominium which the Company acquires to replace it.


                                       9


          (b) Gross Up  Payment.  A payment  that  covers all  federal and state
     income  taxes  payable  by  Employee,  if any,  which  would  not have been
     incurred  by  Employee  if  another  payment or  transfer  and the Gross Up
     Payment had not been made to Employee.

          (c) Change of Control. As defined in paragraph 12 of this Agreement.

          (d) Triggering  Event. A Change of Control,  termination of Employee's
     employment  for any  reason  other  than due to his  breach  of a  material
     provision  of the terms of his  employment  as described in paragraph 11 of
     the Employment  Agreement,  or if he ceases to be Company's chairman of the
     board or chief  executive  officer  for any  reason  other  than due to his
     breach of a material  provision of the terms of his employment as described
     in  paragraph  11 of  the  Employment  Agreement.  Within  10  days  of the
     occurrence of a Triggering Event, Company shall promptly transfer ownership
     of the  Condominium  free and clear of all mortgages,  deeds of trust,  and
     other  encumbrances  to Employee  and, in  addition,  shall pay Employee an
     amount  of cash  equal  to the  Gross Up  Payment.  In the  event  that the
     Condominium  is not  owned by  Company  at such  time,  Company  shall  pay
     Employee in cash an amount equal to the value of the  Condominium  free and
     clear  of  all  mortgages,  deeds  of  trust  and  other  encumbrances  (as
     determined by a reputable appraiser selected by Employee whose fee shall be
     paid one half by each party)  plus the Gross Up Payment.  Within 10 days of
     the  occurrence of a Triggering  Event,  Company shall also pay to Employee
     the sum of $12,105,000.  If the Triggering  Event is the Employee's  death,
     such amount shall be paid to his designated beneficiary,  if any, otherwise
     to his estate.  Company may pay such amount in cash or in Company's  common


                                       10


     stock or in a combination  of cash and common  stock.  Common Stock used in
     payment shall be valued at the average closing price on the Nasdaq National
     Market  over the last 5 business  days prior to the date of the  Triggering
     Event.

     26.  Effect  of  Amendment.  This  amended  and  restated  agreement  shall
supersede all agreements  between the parties relating to Employee's  employment
by Company.

     IN WITNESS WHEREOF, the parties have duly executed this agreement as of the
day and year first above written.
