                              EMPLOYMENT AGREEMENT

          AGREEMENT, effective as of March 6, 2002, between DAVID SORRELLS, with
an address of 3129 Rideout Lane,  Middleburg,  Florida 32068 ("Executive"),  and
PARKERVISION,  INC., a Florida  corporation  having its principle office at 8493
Baymeadows Way, Jacksonville, Florida 32256 ("Company").

          WHEREAS,  Executive has provided his services without the benefit of a
written employment agreement; and

          WHEREAS,   the  Company   believes  that  Executive   provides  unique
management  and  technical  services  for the  Company  and wishes to retain the
continued services of Executive as its Chief Technical Officer ("CTO"); and

          WHEREAS,  the Company and Executive have reached an understanding with
respect to the extension of Executive's  employment  with the Company for a five
(5) year period commencing as of March 6, 2002; and

          WHEREAS,  the Company and Executive desire to evidence their agreement
in writing and to provide for the  employment of Executive by the Company on the
terms set forth herein.

          IT IS AGREED:

1.        Employment, Duties and Acceptance.
          ---------------------------------

1.1       Effective  as of March 6,  2002,  the  Company  hereby  agrees  to the
continued  employment of Executive as its CTO, and to the title of Co-Founder of
the  wireless  division and CTO and  Executive  hereby  accepts  such  continued
employment on the terms and conditions  contained in the  Agreement.  During the
term of this  Agreement,  the  Executive  shall make  himself  available  to the
Company to pursue the  business of the Company  subject to the  supervision  and
direction of the Chairman and Chief Executive Officer of the Company ("CEO").

1.2       The  CEO  may  assign  the  Executive  such  general   management  and
supervisory  responsibilities  and  executive  duties  for  the  Company  as are
appropriate  and  commensurate  with  Executive's  position  as  CTO  and  would
otherwise be consistent in stature and prestige with the  responsibilities  of a
CTO.

                                       3
<PAGE>

1.3       Executive  accepts such employment and agrees to devote  substantially
all of his business  time,  energies and  attention  to the  performance  of his
duties;  provided,  however, that Executive may continue to be actively involved
in  eleemosynary,  educational  and civic  activities  to the  extent  that such
activities do not  materially  detract from the  reasonable  performance  of his
duties (such material  detraction to be evidenced by the CEO's written notice to
Executive, in which event Executive shall have one hundred and twenty (120) days
to reduce the level of such  activities  in a  reasonable  manner).  The Company
recognizes  the  value  to it of  Executive's  continued  involvement  in  these
activities and will reimburse  Executive for reasonable expenses incurred by him
in  connection  with such  activities.  Nothing  herein  shall be  construed  as
preventing  Executive from (i) making and supervising  investments on a personal
or family  basis  (including  trusts,  funds and  investment  entities  in which
Executive or members of his family have an interest)  and (ii) in serving on the
Board of Directors  of not more than three  corporations  involved  primarily in
"for profit" business activities;  provided,  however,  that these activities do
not materially interfere with the performance of his duties hereunder or violate
the provisions of Section 4.4 hereof.

2.        Compensation and Benefits.
          -------------------------

2.1       The Company  shall pay to Executive a salary at an annual base rate of
not less than $250,000. Executive's salary will be paid not less frequently than
every two weeks without the prior written consent of Executive.  After the first
two years of the term of this  Agreement,  Executive's  annual base rate will be
reviewed at least one month prior to the  commencement of each new annual salary
period  during the term hereof for purposes of  determining  whether the minimum
increase is sufficient,  it having been agreed that the minimum annual  increase
after the first two years of this Agreement will be 5%.

2.2       The  Company  shall  also  pay to  Executive  such  bonuses  as may be
determined  from time to time by the CEO. The amount of annual bonus  payable to
Executive may vary at the discretion of the CEO. In determining the annual bonus
to be paid to the Executive, the CEO may, among other factors they believe to be
appropriate,   consider,   and  give  varying  degrees  of  importance  to,  the
Executive's contribution to the following:

                                       4
<PAGE>

(1)       growth in the Company's per share value;

(2)       achievement by the Company of specific  identified targets selected by
the CEO from time to time;

(3)       the  attraction  and  retention  of  key  executive  personnel  by the
Company;

(4)       satisfaction of the Company's capital requirements;

(5)       the  establishment  of strategic  direction  and  significant  Company
goals; and

(6)       such other criteria as the CEO deems to be relevant.

(7)       The Company  shall have the option to adopt an Incentive  Compensation
Program  providing for  compensation  above the  Executive's  salary which shall
supplant any bonuses for any time period the Incentive  Compensation  Program is
in effect.

2.3       Executive has been granted  options to purchase shares of Common Stock
under the Company's Plan as set forth in the attached schedule.  The CEO may, in
his  discretion  and with  approval of the Company's  Board of Directors,  grant
additional options to Executive during the term of this Agreement.

2.4       Executive  shall be  entitled  to such  insurance  and other  benefits
including,  among others,  medical and disability coverage and life insurance as
are afforded to other senior  executives  of the Company,  subject to applicable
waiting  periods and other  conditions  which may be generally  applicable.  The
Company shall purchase (i) long term disability insurance of the amount afforded
to other  senior  executives  of the  Company  except in the  instance  when the
Executive  shall  elect  to pay a  portion  or the  entirety  of the  long  term
disability  insurance  and (ii) the  Company  shall  maintain  a minimum of a $1
million life insurance  policy for the benefit of the  Executive's  heirs except
when the  Executive  shall  elect to pay a portion or the  entirety  of the life
insurance  policy.  At Executive's  option the Executive can pay to increase the
coverage of the life insurance  policy beyond $1 million  coverage to the extent
made available by the insurance  carrier.  The beneficiary of these policies and
the portion, if any, that the Executive shall pay for each policy, which will be
automatically deducted from the Executive's base salary by the Company, shall be
designated  in  writing  by the  Executive  to the CEO and the  Company's  Chief
Accounting  Officer and these  policies shall be transferred to Executive or his
designees by the Company at his written request.

                                       5
<PAGE>

2.5       Executive  shall  be  entitled  to  vacation  time and to days off for
religious and personal  reasons in accordance with the Company's  policy for its
senior executives.

2.6       The Company will pay or reimburse  Executive  for all  transportation,
hotel and other  expenses  incurred by  Executive on business  trips  (including
first class air travel if the scheduled  flight is more than two (2) consecutive
hours) and for all other ordinary and reasonable out-of-pocket expenses actually
incurred by him in the conduct of the business of the Company  against  itemized
vouchers submitted with respect to any such expenses.

2.7       Executive agrees that his services shall be rendered  primarily at the
Company's  executive  offices  which shall be located in, or within  thirty (30)
miles of, the  Company's  current  executive  offices  located in  Jacksonville,
Florida.  Notwithstanding  the  foregoing,  Executive  may  maintain  an  office
adjacent  to his  residence  and shall be  reimbursed  for all costs  reasonably
related thereto.

2.8       The Company shall only move its executive offices if the parties agree
to such a move.  Should the  parties  not agree,  then the  Company can move its
executive  offices and the Company shall either  provide the  Executive  with an
office within 30 miles of the Company's  current  executive  offices  located in
Jacksonville,  Florida,  or if the  Company  does not provide an office then the
executive shall have the right to use his home office and the Company shall also
provide secretarial assistance under this circumstance at the home office if the
Executive so desires.

3.        Term and Termination.
          --------------------

3.1       The term of this  Agreement  commences  as of March 6,  2002 and shall
continue until March 6, 2006, unless sooner terminated as herein provided.

3.2       If Executive  dies during the term of this  Agreement,  this Agreement
shall  thereupon  terminate,  except  that the  Company  shall  pay to the legal
representative of Executive's  estate the base salary due Executive  pursuant to
Section 2.1 hereof through the first  anniversary  of Executive's  death (or the
scheduled  expiration  under Section 3.1, if earlier than the first  anniversary
date)  as  well  as a  pro  rata  allocation  of  bonus  payments  or  incentive
compensation  under Section 2.2 based on the days of service  during the year of
death, and all amounts owing to Executive at the time of termination,  including
for

                                       6
<PAGE>

previously  accrued  but  unpaid  bonuses  or  incentive  compensation,  expense
reimbursements and accrued but unused vacation pay.

3.3       If Executive shall be rendered incapable by an incapacitating  illness
or  disability  (either  physical  or  mental)  of  complying  with  the  terms,
provisions  and  conditions  hereof on his part to be performed  for a period in
excess of 180 consecutive days during any consecutive  twelve (12) month period,
then the Company,  at its option, may terminate this Agreement by written notice
to Executive (the  "Disability  Notice")  delivered  prior to the date Executive
resumes the rendering of services hereunder;  however, if requested by Executive
(or a  representative  thereof)  such  termination  shall not occur  until after
examination of Executive by a medical  doctor  (retained by the Company with the
consent of the Executive which consent shall not be  unreasonably  withheld) who
certifies  in a written  report to the CEO with a copy of such report  delivered
simultaneously  to  Executive  that  Executive  is and  shall  be  incapable  of
performing  his duties  for in excess of two  additional  months  because of the
continuing   existence   of   such   incapacitating   illness   or   disability.
Notwithstanding such termination,  the Company shall make a payment to Executive
of a pro rata  allocation  of  payments  under  Section 2.2 based on the days of
service during the year in which the Disability Notice is delivered. The Company
shall  also pay to  Executive  all  amounts  owing to  Executive  at the time of
termination,  including for  previously  accrued but unpaid bonuses or incentive
compensation, expense reimbursements and accrued but unused vacation pay. At the
Executive's  request,  the Company  shall  provide to Executive at the Company's
expense,  an office for his exclusive use at the Company's  principal  executive
offices with full time confidential  secretarial  assistance and office services
during the Disability Period

3.4       The Company, by notice to Executive,  may terminate this Agreement for
cause.  As used herein,  "cause"  shall  include (a) the refusal in bad faith by
Executive to carry out specific  written  directions of the CEO, (b) intentional
fraud or  dishonest  action  by  Executive  in his  relations  with the  Company
("dishonest"  for these purposes shall mean  Executive's  knowingly  making of a
material  misstatement  to the CEO for the purpose of obtaining  direct personal
benefit);  or (c) the  conviction of Executive of any crime  involving an act of
significant  moral  turpitude  after appeal or the period for appeal has elapsed
without an appeal being filed by Executive.  Notwithstanding  the foregoing,  no
"cause" for

                                       7
<PAGE>

termination  shall be deemed to exist with respect to Executive's acts described
in clause (a) or (b) above,  unless the CEO shall have given  written  notice to
Executive  (after  five (5) days  advance  written  notice  to  Executive  and a
reasonable  opportunity  to  Executive  to present his views with respect to the
existence of "cause"),  specifying the "cause" with  particularity  and,  within
twenty (20) business days after such notice,  Executive  shall not have disputed
the CEO's  determination  or in  reasonably  good faith taken  action to cure or
eliminate  prospectively  the  problem  or thing  giving  rise to such  "cause,"
provided,  however,  that a  repeated  breach  after  notice  and  cure,  of any
provision  of  clause  (a) or (b)  above,  involving  the same or  substantially
similar actions or conduct,  shall be grounds for termination for cause upon not
less than five (5) days  additional  notice from the Company.  In the event of a
dispute as to the  existence  of suitable  "cause" for  termination  pursuant to
Section 3.4, Executive shall be entitled to file for arbitration of such dispute
in accordance with the rules of the American  Arbitration  Association  with one
arbitrator  to be selected by the Company and one  arbitrator  to be selected by
the Executive,  and pending final determination of such arbitration proceedings,
Executive  shall  continue to be  compensated  and shall be  reimbursed  for his
expenses  including  his  legal  costs  in  accordance  with  the  terms of this
Agreement.

3.5       The Executive,  by notice to the Company, may terminate this Agreement
if a "Good Reason" exists.  For purposes of this Agreement,  "Good Reason" shall
mean  the  occurrence  of  any  of  the  following   circumstances  without  the
Executive's prior express written consent;  (a) a material adverse change in the
nature of Executive's title,  duties or  responsibilities  with the Company that
represents a demotion from his title,  duties or  responsibilities  as in effect
immediately prior to such change; (b) a material breach of this Agreement by the
Company; (c) a failure by the Company to make any payment to Executive when due,
unless the payment is not  material and is being  contested  by the Company,  in
good faith; (d) a liquidation, bankruptcy or receivership of the Company; or (e)
if  Executive  is at any time  not a member  of the  Board of  Directors  of the
Company unless he voluntarily resigns therefrom.  Notwithstanding the foregoing,
no Good  Reason  shall be deemed to exist  with  respect to the  Company's  acts
described in clauses (a), (b) or (c) above,  unless  Executive  shall have given
written  notice  to the  Company  specifying  the Good  Reason  with  reasonable
particularity  and,  within  twenty (20)  business  days afer such  notice,  the
Company shall not have cured or  eliminated  the problem or thing giving rise to
such Good Reason; provided

                                       8
<PAGE>

however,  that a  repeated  breach  after  notice and cure of any  provision  of
clauses  (a),  (b) or (c)  above  involving  the same or  substantially  similar
actions or conduct, shall be grounds for termination for Good Reason without any
additional notice from Executive.

3.6       In the event that Executive terminates this Agreement for Good Reason,
pursuant to the  provisions  of paragraph  3.5, or the Company  terminates  this
Agreement  without  "Cause," as defined in  paragraph  3.4,  the  Company  shall
continue  to pay  to  Executive  (or  in  the  case  of  his  death,  the  legal
representative  of  Executive's  estate  or such  other  person  or  persons  as
Executive shall have designated by written notice to the Company), all payments,
compensation and benefits  required under paragraph 2 hereof through the earlier
of (a) three (3) years from the date of  termination  or (b) through the term of
this Agreement;  provided,  however,  that (i) a minimum payment of no less than
the  average  of  the  two  prior  years'  bonuses,  incentive  compensation  or
combination thereof shall be paid; and (ii) Executive's insurance coverage shall
terminate upon the Executive  becoming covered under a similar program by reason
of employment  elsewhere;  however, in the absence of being covered by reason of
employment elsewhere the Company shall pay for Executive's insurance coverage to
the maximum  COBRA limits.  If  Executive's  employment  is terminated  for Good
Reason or without "Cause,"  Executive shall have no duty to mitigate awards paid
or payable to him  pursuant to this  subsection,  and any  compensation  paid or
payable to  Executive  from  sources  other than the Company  will not offset or
terminate the Company's obligation to pay to Executive the full amounts pursuant
to this subsection 3.6.

4.        Non-Competition and Confidentiality.
          -----------------------------------

4.1       During  Executive's  employment  with the  Company and for a period as
determined by the restrictive  covenant  defined below,  whatever the reason for
Executive's  termination of employment,  Executive shall not, either directly or
indirectly, either on his own behalf or on behalf of another business, engage in
the  following  activities,  or assist  others in such  activities:  (a) hiring,
recruiting,  or  attempting  to recruit for any entity which  competes  with the
Company in the areas of radio-based  communications,  studio  automation  and/or
webcasting  ("Competing  Areas"),  or otherwise becoming  associated in any such
business  with,  any person  employed  by the  Company,  at any time  during the
previous twelve (12) months;  (b) soliciting or accepting any business in any of
the Competing Areas (on behalf of

                                       9
<PAGE>

anyone  other than the Company)  from any of the  Company's  current,  former or
prospective  accounts (a prospective  account  defined as any entity the Company
has actively  solicited,  planned to solicit,  or provided  services to,  during
Executive's  employment  with the Company);  or (c) entering into,  engaging in,
being  employed  by, being  connected  to, or  consulting  for, any entity which
competes with the Company in any of the Competing Areas.

          The term of the above  restrictive  covenant shall be calculated based
on  the  total  of  the  following:  (a)  additional  salary,  bonus,  incentive
compensation or any other payment which  Executive  receives above the amount of
his base salary during the 12 month period immediately preceding the termination
of his employment or within 10 working days thereafter,  (b) gains from exercise
of any options to purchase shares of the Company which is realized during the 12
month period  immediately  preceding the termination of his employment,  and (c)
the value of share  options  available  for Executive to exercise on the date of
the  termination  of  Executive's  employment  based on the option price and the
quoted  price  per  share at the  close of that  date.  The  total of all of the
foregoing  shall be termed herein "Excess  Compensation".  The term of the above
restrictive  covenant shall be as follows: 1 year if Excess Compensation exceeds
2 times Executive's ending base salary, 2 years if Excess Compensation exceeds 3
times Executive's ending base salary, and 5 years if Excess Compensation exceeds
5  times  Executive's  ending  annual  base  salary.  Upon  the  termination  of
Executive's employment, the Company has the option of paying Executive monies to
include as Excess  Compensation  for the purpose of determining  the term of the
restrictive covenant as an advance against potential gains Executive may realize
as a result of his subsequent exercise of share options; such monies can be paid
in cash or in  registered  shares of the Company's  publicly  traded stock which
Executive  agrees after receipt of shares to sell in the stock market as quickly
as  possible  but not more  shares  than are equal to 10% of the  average  daily
trading  volume of the prior 10 trading days to  receiving  the shares of stock,
the Company agrees to pay the Executive the difference in cash should there be a
shortfall  of what the  Executive  realizes  in  selling  the  stock in the open
market.  If the  Company  pays  such  an  advance,  and  Executive  subsequently
exercises  share options which  realizes a gain above whatever  Executive  could
have  realized if he had  exercised  his options at the close of the date of the
termination of his employment, Executive must repay to the Company the amount of
the  advance  or this gain,  whichever  is less.  In the event

                                       10

that the Company chooses to issue registered shares of its stock to cover all or
part of the Excess Compensation  requirement(s) for the restrictive  covenant as
defined in this section,  the registered shares shall be delivered as a tradable
security to the  Executive no later than one hundred and twenty (120) days after
the executive's last day of employment by the Company.

4.2       The parties to this Agreement  recognize that  irreparable  harm would
result from any breach by Executive of the covenants of this  Agreement and that
monetary  damages alone would not provide  adequate  relief for any such breach.
Accordingly,  in  addition to any other  remedy  which may be  available  to the
Company,  if Executive  breaches a restrictive  covenant in this Agreement,  the
parties acknowledge that injunctive relief in favor of the Company is proper.

4.3       If Executive breaches a covenant containing a specified term, the term
shall be  extended  by the period of time  between  Executive's  termination  of
employment  with the  Company  and the date a court  of  competent  jurisdiction
enters an injunction restraining further breach of the covenant.

4.4       If a  court  of  competent  jurisdiction  determines  that  any of the
restrictions  in  this  Agreement  are  overbroad,   Executive  shall  agree  to
modification of the affected restriction(s) to permit enforcement to the maximum
extent allowed by law.

4.5       A waiver of any of Executive's obligations under this Agreement or any
other modification of this Agreement shall be ineffective unless it is set forth
in writing and signed by the Company's CEO.

4.6       The  parties  acknowledge  that  the  restrictive  covenants  in  this
Agreement are essential  independent elements of this Agreement and that but for
Executive  agreeing to comply with them,  the Company would not have employed or
have continued to employ Executive.  Accordingly,  the existence of any claim by
Executive  against the Company,  whether  based on this  Agreement or otherwise,
shall not operate as a defense to the Company's  enforcement of any  restrictive
covenant against Executive.

                                       11

4.7       Executive shall abide by paragraphs 1-7, 11-13 and 15 of the Company's
current Employee Agreement, a copy of which is attached hereto, which paragraphs
are hereby incorporated into this Agreement in their entirety.

5.2       In the event of any claims,  litigation or other  proceedings  arising

the Executive  shall be reimbursed by the Company  within thirty (30) days after
delivery to the Company of statements for the costs incurred by the Executive in
connection  with  the  analysis,  defense  and  prosecution  thereof,  including
reasonable attorneys' fees and expenses; provided, however, that Executive shall
reimburse the Company for all such costs if it is determined by a non-appealable
final decision of a court of law that the Executive shall have acted in bad

faith with the intent to cause material damage to the Company in connection with

Executive for any liability,  damages, losses, costs and expenses arising out of

subsidiary.  To the  extent  that the  Company  obtains  director  and  officers

consultant  to the  Company,  Executive  shall be a named  insured  and shall be
entitled to coverage thereunder.

referenced  in  section  4.7 above , and the Stock  Option  Agreements  attached
herein set forth the entire  agreement of the parties relating to the employment
of   Executive   and  are  intended  to   supersede   all  prior   negotiations,
understandings  and  agreements.  No provisions  of this  Agreement or the Stock
Option  Agreements  may be waived or  changed  except by a writing  by the party
against whom such waiver or change is sought to be enforced.  The failure of any
party to require  performance  of any  provision  hereof or thereof  shall in no
manner affect the right at a later time to enforce such provision.

5.6       All questions with respect to the construction of this Agreement,  and
the rights and  obligations  of the parties  hereunder,  shall be  determined in
accordance  with the law of the State of Florida  applicable to agreements  made
and to be performed entirely in Florida.

5.7       This  Agreement  shall inure to the benefit of and be binding upon the
successors and assigns of the Company. This Agreement shall not be assignable by
Executive,  but shall  inure to the benefit of and be binding  upon  Executive's
heirs and legal representatives.

5.8       Should any provision of this agreement  become legally  unenforceable,
no other provision of this Agreement shall be affected, and this Agreement shall
continue  as if  the  Agreement  had  been  executed  absent  the  unenforceable
provision.
