November,  2000, between Pro Tech  Communications,  Inc., a Florida  corporation
(the "Company"),  having its principal  executive office at 3311 Industrial 25th

     On March 5, 1998, the Company's  Board of Directors  adopted the 1998 Stock
Option  Plan  (the  "Plan"),  under  which  Options  to  purchase  shares of the
Company's common stock, par value $.001 per share (the "Common Stock"), could be
granted to officers,  employees,  and certain  directors and  consultants of the
Company.  On April 15,  1998,  the  stockholders  of the  Company  approved  the
adoption of the Plan.

     On April 26,  2000,  the Board of  Directors  amended the Plan,  subject to
shareholder approval, to increase the number of shares covered under the Plan to
2,000,000  shares of the  Company's  Common  Stock.  On August 11, 2000,  at the
adjourned  annual  meeting of  stockholders,  the  stockholders  of the  Company
approved the adoption of the  amendment  to the Plan,  increasing  the number of
shares of the Company's  Common Stock covered under the Plan from 500,000 shares
to 2,000,000 shares. Capitalized terms used herein and not defined have the same
meanings as set forth in the Plan.

     Pursuant to said Plan, the Company hereby grants to Optionee a nonstatutory
stock option to acquire Common Stock of the Company upon the following terms and
conditions:

     1. Grant of Option.  The Company  hereby grants to Optionee a  nonstatutory
stock  option (the  "Option")  to purchase  (subject to  adjustment  pursuant to
Section 9 of the Plan) up to two hundred fifty thousand (250,000) fully paid and
nonassessable  shares of the Common Stock of the Company (the  "Shares"),  to be
issued upon the exercise thereof, as set forth below.

     2. Exercise  Price.  The exercise  price of the Option shall be $0.4375 per
share.  The  Company  shall  pay all  original  issue or  transfer  taxes on the
exercise of the Option.

     3. Limitation on Exercisability of Option.  The Option granted hereby shall
vest and become fully exercisable as follows (the "Vesting Dates"):

                  As to 25%   November 28, 2000
                  As to 25%   November 28, 2001
                  As to 25%   November 28, 2002
                  As to 25%   November 28, 2003

After each Vesting Date,  the  applicable  Shares  becoming  exercisable  on the
Vesting  Date in  question  shall be  exercisable  in whole or in part until the
expiration of the Option.

     4. Expiration of Option. The Option shall not be exercisable after November
28, 2007.

     5.  Non-Assignability  of Option.  The Option shall not be given,  granted,
sold,  exchanged,  transferred,  pledged,  assigned or otherwise  encumbered  or
disposed  of by  Optionee,  otherwise  than by will or the laws of  descent  and
distribution,  and during the lifetime of Optionee, shall be exercisable only by
the Optionee or his or her agent, attorney-in-fact, or guardian.

     6.  Method of  Exercise  of Option.  Optionee  shall  notify the Company by
written notice sent by registered or certified mail,  return receipt  requested,
addressed to its principal office, or by hand delivery to such office,  properly
receipted,  as to the number of Shares which Optionee  desires to purchase under
the Option,  which  written  notice shall be  accompanied  by cash or Optionee's
check  payable to the order of the Company for the full  exercise  price of such
Shares  and the  amount of any  withholding  tax  obligation  of the  Company as
described in Section 14(a) of the Plan. As soon as practicable after the receipt
of such written notice,  the Company shall, at its principal  office,  tender to
Optionee a certificate or certificates  issued in Optionee's name evidencing the
Shares purchased by Optionee hereunder.

     7. Termination of Employment or Services.

          (a)  Termination  by Reason of Death or  Disability.  In the event the
               employment  of  Optionee  is  terminated  by  reason  of death or
               disability,  any  Option  granted to  Optionee  that has not been
               exercised  prior to the date of  termination of employment may be
               exercised by Optionee  (or the heirs or legatees of Optionee,  as
               applicable)  at any time within  twelve  (12)  months  after such
               termination  of  employment,  unless  the  Option,  by its  term,
               expires earlier.

          (b)  Termination  by  Retirement.  In  the  event  the  employment  of
               Optionee  is  terminated  by reason  of  retirement,  any  Option
               granted to Optionee that has not been exercised prior to the date
               of termination of employment may be exercised by Optionee (or the
               heirs or legatees of Optionee,  as applicable) at any time within
               twelve (12) months after such  termination of employment,  unless
               the Option, by its term, expires earlier.  For the purpose of the
               Plan and this Agreement,  the criteria for retirement are defined
               as an employee whose age in years on the date of retirement  when
               added  to the  number  of years of  continuous  service  with the
               Company  and its  subsidiaries  immediately  preceding  such date
               equals a number greater than fifty-one (51),  provided the number
               of such years of service is not less than five (5). Exceptions to
               these  criteria may be made by action of the  Company's  Board of
               Directors.

          (c)  Termination  by  Resignation.  In the  event  the  employment  of
               Optionee is terminated by reason of resignation,  any outstanding
               Option  granted to the Optionee which is vested as of the date of
               notice of resignation may be exercised by the Optionee within the
               period  beginning on the date of such notice of  resignation  and
               ending  three (3) months after such date,  unless the Option,  by
               its term, expires earlier.

          (d)  Termination of Employment for Other Reasons. If the employment of
               Optionee  shall  terminate  for any reason other than the reasons
               set forth in (a), (b) or (c) above, and other than for cause, any
               Option granted to the Optionee that has not been exercised  prior
               to the date of  termination of employment may be exercised by the
               Optionee  within the period  beginning on the date of such notice
               of  resignation  and  ending  three (3)  months  after such date,
               unless the Option, by its term, expires earlier.

          (e)  Termination  for  Cause.  If the  employment  of  Optionee  shall
               terminate  for cause,  all  outstanding  Options held by Optionee
               shall  immediately  terminate  and be  forfeited  to the  Company
               immediately upon notice, and no additional  exercise period shall
               be allowed.

     8. Shares of Common Stock as Investment.  By accepting the Option, Optionee
agrees that any and all Shares  purchased  upon the  exercise  thereof  shall be
acquired for investment and not for  distribution,  and upon the issuance of any
or all of the  Shares  subject  to the  Option,  Optionee  shall  deliver to the
Company a representation  in writing that such Shares are being acquired in good
faith for  investment  and not with a view toward  resale or  distribution.  The
Company  may  place an  appropriate  restrictive  legend on the  certificate  or
certificates evidencing such Shares.

     9. Adjustments upon Changes in  Capitalization.  In the event of changes in
the outstanding Common Stock of the Company by reason of stock dividends,  stock
splits, recapitalizations,  mergers, consolidations,  combinations, exchanges of
shares,  separations,  reorganization,  or  liquidations,  the  number of Shares
issuable upon the exercise of the Option, and the exercise price thereof and any
limitation on exercise set forth in Paragraph 3 hereof shall be  correspondingly
adjusted by the Company in  accordance  with the  provisions of Section 9 of the
Plan. Any such adjustment in the number of Shares shall apply proportionately to
only the then  unexercised  portion of the Option.  If  fractional  shares would
result from any such  adjustment,  the  adjustment  shall be revised to the next
lower whole number of shares.

     10.  No  Rights  as  Stockholders.  Optionee  shall  have  no  rights  as a
stockholder  in respect to the Shares as to which the Option shall not have been
exercised and payment made as herein provided.

     11. Binding Effect.  Except as herein otherwise  expressly  provided,  this
Agreement  shall be binding upon and inure to the benefit of the parties hereto,
their legal representatives, successors and assigns.

     12. The Stock Option Plan. This Agreement and the Option granted  hereunder
are  subject  to the  terms  and  conditions  of the  Plan,  a copy of  which is
available at the Optionee's request and is on file in the Company's offices.

     13.  Governing  Law. This  Agreement  shall be governed by and construed in
accordance with the laws of the State of Florida.

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