                             STOCK OPTION AGREEMENT

         OPTION AGREEMENT dated as of August 4, 1998 between Pro Tech
Communications, Inc., a Florida corporation (the "Company"), having its
principal executive office at 3311 Industrial 25th Street, Ft. Pierce, Florida
34946 and Ken Campbell (the "Optionee"), having his/her address at 1796
Walden Pond Drive, Ft Pierce FL 34945-2418.

         The Company has adopted the 1998 Stock Option Plan (the "Plan"), a copy
of which is attached hereto, and desires to grant to the Optionee the
Nonstatutory Stock Option provided for herein, all subject to the terms and
conditions of the Plan. Capitalized terms used herein and not defined have the
same meanings as set forth in the Plan.

         IT IS AGREED as follows:

         1.    Grant of Option. The Company hereby grants to the Optionee on the
date hereof a Nonstatutory Stock Option (the "Option") to purchase (subject to
adjustment pursuant to Section 9 of the Plan) an aggregate of 50,000 of its
shares of Common Stock (the "Shares") at an option price per Share of $.375.

         2.    Option Period. The Option granted hereby all expire on August 4,
2001 subject to earlier termination as provided in the Plan.

         3.    Exercise of Option.

               A.    The Optionee may immediately exercise the Option, or any 
portion thereof, until August 3, 2001.

               B.    The Optionee may exercise the Option, or any portion
thereof, by delivering to the Company a written notice duly signed by the
Optionee in the form attached hereto as Exhibit A stating the number of
Shares that the Optionee has elected to purchase, and accompanied by payment (in
cash or by certified check) of an amount equal to the sum of (i) the full
purchase price for the Shares to be purchased, plus (ii) any withholding tax
required to be paid pursuant to Section 14(a) of the Plan. After receipt by the
Company of such notice and payment, the Company shall (subject to Section 10 of
the Plan) issue the Shares in the name of the Optionee and deliver the
certificate therefor to the Optionee. No Shares shall be issued until full 
payment therefor and any withholding tax has been made, and the Optionee shall
have none of the rights of a shareholder in respect of such Shares until they
are issued.

         4.    Employment. Nothing contained in this Option Agreement shall
confer upon the Optionee any right to be employed by the Company nor prevent the
Company from terminating its current relationship with the Optionee at any time,
with or without cause. If the Optionee's current relationship with the Company
is terminated for any reason (including by resignation), the Option shall

be exercisable only as to those Shares immediately purchasable by the Optionee
at the date of termination and, subject to Section 2 hereof, thereafter as
provided in the Plan.

         5.    Transferability of Option. The Option may not be transferred
other than by laws of descent and distribution, provided, however, that if Form
S-8 under the Securities Act of 1933 is hereafter amended to permit the transfer
of an option to family members by gift or otherwise, then this Option may be so
transferred to family members in accordance with and to the full extent
permitted by Form S-8.

         6.    Tax Status. The company makes no representation or warranty
whatsoever to the Optionee as to the tax consequences of the grant or exercise
of the Option or of the disposition of Shares acquired thereunder.

         7.    Incorporation of Plan. The Option granted hereby is subject to,
and governed by, all the terms and conditions of the Plan, which are hereby
incorporated by reference. This Agreement, including the Plan incorporated by
reference herein, is the entire agreement among the parties hereto with respect
to the subject matter hereof and supersedes all prior agreements and
understandings. In the case of any conflict between the terms of this Agreement
and the Plan, the provisions of the Plan shall control.

         8.    Purchase for Investment. As a condition to the exercise in whole
or in part of the Option hereby granted, each written notice of election shall
include a representation by the Optionee that the Shares are being purchased for
investment and not for distribution or resale.

         9.    Notices. Any notice to be given by the Optionee hereunder shall 
be sent to the Company at its principal executive offices, and any notice from
the Company to the Optionee shall be sent to the Optionee at his address set
forth above; all such notices shall be in writing and shall be delivered in
person or by registered or certified mail. Either party may change the address
to which notices are to be sent by notice in writing given to the other in
accordance with the terms hereof.

         10.   Governing Law. This Option Agreement shall be governed by 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.
