                              EMPLOYMENT AGREEMENT

This Employment Agreement ("Agreement") is made as of May 3, 2000 by and between
Able Telcom Holding Corp., a Florida corporation (the "Company"), and Edwin D.
Johnson (hereinafter, the "Executive").

                                    RECITALS

                           A.    The Board of Directors of the Company (the
"Board") recognizes the Executive's potential contribution to the growth and
success of the Company, and desires to assure the Company of the Executive's
employment in an executive capacity and to compensate him therefor, and has
approved the provisions of this Agreement and has authorized the officers of the
Company to execute the Agreement on behalf of the Company.

                           B.    The Executive is willing to make his
services available to the Company and on the terms and conditions hereinafter
set forth.

                                    AGREEMENT

         NOW, THEREFORE, in consideration of the premises and mutual covenants
set forth herein, the parties agree as follows:

         1.       Employment.

                  1.1.     Employment and Term. The Company hereby agrees to
employ the Executive and the Executive hereby agrees to serve the Company on the
terms and conditions set forth herein.

                  1.2.     Duties of Executive. During the Term of Employment
under this Agreement, the Executive shall serve as the President and Chief
Executive Officer of the Company. The Executive shall also serve as a member of
the Board and Chairman of the Executive Committee during the Term of Employment
under this Agreement. The Executive shall be accountable only to the Chief
Executive Officer of the Company, and, subject to the authority of the Chief
Executive Officer, shall have supervision and control over, and responsibility
for, the general management and operation of the Company. He also shall have
such other powers and duties as may from time to time be prescribed by the
Board, provided that such duties are consistent with the Executive's position as
President and Chief Executive Officer of a company the size and type of the
Company. The Executive shall devote his full time and attention to the business
and affairs of the Company, render such services to the best of his ability, and
use his reasonable best efforts to promote the interests of the Company.
Notwithstanding the foregoing or any other provision of this Agreement, it shall
not be a breach or violation of this Agreement for the Executive to (i) serve on
corporate (subject to approval of the Board), civic or charitable boards or
committees, (ii) deliver lectures, fulfill speaking engagements or teach at
educational institutions, or (iii) manage personal investment, so long as such
activities do not significantly interfere with or significantly detract from the
performance of


                                       1
<PAGE>   2

the Executive's responsibilities to the Company in accordance with this
Agreement. The Executive may continue to serve out the remaining term as a board
member on any corporate board on which he serves as of the Commencement Date.

         2.       Term.

                  2.1.     Term. The term of employment under this Agreement
(the "Term of Employment") shall commence as of May 8, 2000 (the "Commencement
Date") and shall continue for a period ending three (3) years from any date as
of which the Term of Employment is being determined, subject to earlier
termination pursuant to Section 5 hereof. The date on which the Term of
Employment shall expire is sometimes referred to in this Agreement as the
"Expiration Date".

         3.       Compensation.

                  3.1.     Base Salary. The Executive shall receive a base
salary at the annual rate of $300,000 (the "Base Salary") during the Term of
Employment, with such Base Salary payable in installments consistent with the
Company's normal payroll schedule, subject to applicable withholding and other
taxes. The Base Salary shall be reviewed, at least annually, for merit increases
and may, by action and in the discretion of the Chief Executive Officer, be
increased at any time or from time to time. The Executive's Base Salary at any
point in time shall not be decreased for any reason.

         3.2.     Bonuses.

                  a.       Formula Bonus: For each Bonus Period that begins on
or after November 1, 2000 during the Term of Employment, the Executive shall be
paid an annual formula bonus (the "Formula Bonus") during the Term of Employment
equal to the greater of (i) the Minimum Annual Bonus, or (ii) the bonus
determined pursuant to a formula (the "Formula") established by the Board at the
beginning of each Bonus Period that commences during the Term of Employment. The
Minimum Annual Bonus shall be $150,000 and, subject to the Board's approval, may
be payable on each July 31, October 31, January 31, and April 30. To establish
the Formula, within the first three (3) months of each Bonus Period for which a
Formula Bonus may be payable pursuant to this Section 3.2 the Board shall (x)
assign the Executive a percentage of his Base Salary that may be earned as a
bonus (the "Target Award Percentage"), which shall not be less than 100%, and
(y) assign reasonable financial performance targets for the Company by which to
measure the Executive's performance. At the end of each such Bonus Period, the
Board will determine a percentage that reflects the Company's actual financial
performance in relation to the financial performance targets set for the Company
("Percent of Target Award Earned"). The Executive's bonus pursuant to the
Formula will be determined as follows:

  (TARGET AWARD PERCENTAGE) X (BASE SALARY) X (PERCENT OF TARGET AWARD EARNED).

         The amount of the bonus payable to Executive shall be determined as
promptly as practicable after the determination of the Company's financial
performance for the Bonus Period.


                                       2
<PAGE>   3

If and to the extent that the amount of the bonus for the Bonus Period
determined pursuant to the Formula exceeds the Minimum Annual Bonus, the Company
shall pay the excess to the Executive within 2 1/2 months after the end of the
Bonus Period for which it is payable.

                  b.       Termination Year Bonus. For the Bonus Period in which
the Executive's employment with the Company terminates for any reason, the
Company shall pay the Executive a pro rata portion (based upon the period ending
on the date on which the Executive's employment with the Company terminates) of
the bonus otherwise payable under Section 3.2b for the Bonus Period in which
such termination of employment occurs; provided, however, that (i) the Bonus
Period shall be deemed to end on the last day of the fiscal quarter of the
Company in which the Executive's employment so terminates, and (ii) the business
criteria used to determine the bonus for this short Bonus Period shall be
annualized and shall be determined based upon unaudited financial information
prepared in accordance with generally accepted accounting principles, applied
consistently with prior periods, and reviewed and approved by the Compensation
Committee of Board. The Incentive Compensation for this Bonus Period is
sometimes hereinafter referred to as the "Termination Year Bonus."

                  c.       Additional Bonuses.

                           (i)      For  purposes  of the period  between the
Commencement Date and October 31, 2000, the Company shall pay to the Executive a
bonus (the "Initial Bonus"), the amount of which shall be determined by the
Board based upon stock performance criteria, but which shall not be less than
$75,000. The Initial Bonus shall be payable on October 31, 2000.

                           (ii)     The Company shall pay to the Executive
additional bonuses (the "Special Bonuses"), payable as and when payments on the
Loans (as described in Section 4.6), if any, are due and payable by the
Executive to the Company, in amounts such that after payment by the Executive of
all federal, state and or local taxes imposed upon the Special Bonus, the
Executive retains an amount sufficient to repay that portion (both principal and
interest) of the Loans advanced by the Company to the Executive pursuant to
Subsection 3(a) hereof that is then due and payable by the Executive. The
Company may offset and apply the amount of the Special Bonus against the amounts
(both principal and interest) then due and payable on the Loans.

                           (iii)    In the event that the Executive's employment
with the Company is terminated for any reason other than by the Executive
without Good Reason pursuant to Section 5.5(b) hereof, the Company shall pay to
the Executive an additional bonus (the "Additional Special Bonus"), payable
within thirty (30) days of the date of the termination of the Executive's
employment, in an amount such that after payment by the Executive of all
federal, state and/or local taxes imposed upon the Additional Special Bonus, the
Executive retains an amount sufficient to repay that portion (both principal and
interest) of the Loans advanced by the Company to the Executive pursuant to
Subsection 3(a) hereof that is due and payable by the Executive at that time.
The Company can offset and apply the amount of the Additional Special Bonus
against the amounts of the principal and interest then due and payable


                                       3
<PAGE>   4

on the Loans.

                           (iv)     The Executive shall receive such additional
bonuses, if any, as the Board may in its sole and absolute discretion determine.

                           d.       Definitions. Any bonuses, other than the
Special Bonuses and the Additional Special Bonus, payable pursuant to this
Section 3.2 are sometimes hereinafter referred to as "Incentive Compensation."
Each period for which Incentive Compensation is payable under this Section 3.2
is sometimes hereinafter referred to as a Bonus Period. Except as otherwise
provided in Section 3.2c, and unless otherwise agreed to by the Board and the
Executive, the Bonus Period shall be the fiscal year of the Company.

                           e.       Time of Payment. Except as otherwise
provided herein, any Incentive Compensation payable pursuant to this Section 3.2
shall be paid by the Company to the Executive within 2 1/2 months after the end
of the Bonus Period for which it is payable.

         4.       Expense Reimbursement and Other Benefits.

                  4.1.     Reimbursement of Expenses. Upon the submission of
proper substantiation by the Executive, and subject to such rules and guidelines
as the Company may from time to time adopt with respect to the reimbursement of
expenses of executive personnel, the Company shall reimburse the Executive for
all reasonable expenses actually paid or incurred by the Executive during the
Term of Employment in the course of and pursuant to the business of the Company.
The Executive shall account to the Company in writing for all expenses for which
reimbursement is sought and shall supply to the Company copies of all relevant
invoices, receipts or other evidence reasonably requested by the Company.

                  4.2.     Compensation/Benefit Programs/Life Insurance. During
the Term of Employment, the Executive shall be entitled to participate in all
medical, dental, hospitalization, accidental death and dismemberment,
disability, travel and life insurance plans and all other plans as are presently
and hereinafter offered by the Company to its executive personnel, including
savings, pension, profit-sharing and deferred compensation plans. In addition,
the Company shall obtain, pay for and keep in force at all times while the
Executive is employed by the Company (and thereafter when required by this
Agreement) a term life insurance policy on the life of the Executive with a
death benefit not less than $1,000,000; provided that if the Executive is not
insurable at the insurer's lowest rates for healthy, non-smoking males of the
Executive's age (the "Non-Rated Premiums"), then the Company shall obtain and
pay for an insurance policy on the life of the Executive in the face amount
obtainable for such Non-Rated Premiums. The Executive shall have the exclusive
right to own and designate the beneficiaries of any life insurance policy
provided by the Company hereunder and to change the beneficiaries from time to
time. Such policy and the proceeds and cash value thereof, if any, shall be the
sole property of the Executive and the Company shall not retain and beneficial
interest therein.

                  4.3.     Working Facilities. During the Term of Employment,
the Company shall furnish the Executive with an office, secretarial help and
such other facilities and services suitable to his position and adequate for the
performance of his duties hereunder.

                  4.4.     Automobile. During the Term of Employment, the
Company shall, at the Executive's election, either (i) pay to the Executive a
non-accountable automobile allowance of $1,500 per month or (ii) provide the
Executive with a mid-size automobile (which initially shall be new and shall be
replaced not less frequently than every three (3) years), and reimburse the
Executive for the costs of gasoline, oil, repairs, maintenance, insurance and
other expenses incurred by Executive by reason of the use of the automobile.

                  4.5.     Stock Options.

                           a.       Initial Grant. As of the Commencement Date,
the Company shall grant to the Executive, an option to purchase one hundred
thousand (150,000) shares of common stock of the Company (the "Initial Options")
at the closing price on the Commencement Date. This option shall be immediately
exercisable in full and shall remain exercisable for a period of ten (10) years,
whether or not the Executive continues to be employed by the Company during that
period. The parties intend that the Initial Options be granted pursuant to the
Company's stock option plan (the "Stock Option Plan") and shall be incentive
stock options to the extent allowable under the Stock Option Plan and applicable
laws; provided, however, in the event that the Initial Options may not be
granted under the Stock Option Plan due to the failure of the Company to obtain
shareholder approval of an increase in the number of shares available for grant
thereunder, the Initial Options shall be granted to the Executive outside of the
Stock Option Plan.

                           b.       Future Grants. In addition, during the Term
of Employment, the Executive shall be eligible to be granted options (the "Stock
Options") to purchase common stock (the "Common Stock") of the Company under
(and therefore subject to all terms and conditions of) the Company's Stock
Option Plan, and any successor plan thereto (the "Stock Option Plan"); provided,
however, that the Stock Options shall become immediately exercisable in full
upon termination of the Executive's employment with the Company for any reason
other than termination by the Company for Cause under Section 5.1 hereof or
termination by the Executive Without Good Reason under Section 5.5b hereof. The
number of Stock Options and terms and conditions of the Stock Options shall be
determined by the committee of the Board appointed pursuant to the Stock Option
Plan, or by the Board of Directors of the Company, in its discretion and
pursuant to the Stock Option Plan.

                  4.6.     Loans. Immediately upon execution of this Agreement,
in consideration of benefits and opportunities the Executive must relinquish in
connection with his current employment, and for other good and valuable
consideration, the Executive shall receive a loan from the Company in an amount
equal to $100,000, repayable in three (3) equal annual installments on each of
the first, second and third anniversaries of the Commencement Date hereof. In
addition, the Company shall loan to the Executive up to an aggregate additional
amount of $150,000 upon request by the Executive at any time during the one (1)
year period


                                       5

commencing on the Commencement Date hereof, and any such loan(s) shall be
repayable in three (3) equal annual installments on each of the first, second
and third anniversaries of the date on which the additional loan(s) are made.
The Company must fund any loan request within 72 hours of receiving written
notification from the Executive. The loans described in this Section 4.6 shall
collectively be referred to in this Agreement as the "Loans." The Loans shall
bear interest at a fixed rate equal to the prime rate as published by the Bank
of Wachovia for the business day immediately preceding the date on which the
loan is made. During the period in which the Executive is employed by the
Company, payments on the Loans shall be made solely from the proceeds of the
Additional Bonuses payable by the Company to the Executive pursuant to Section
3.2(c)(ii) hereof. Upon termination of the Executive's employment with the
Company for any reason other than by the Executive without Good Reason pursuant
to Section 5.5(b) hereof, payments on the Loans shall be made solely from the
proceeds of the Special Additional Bonus payable by the Company to the Executive
pursuant to Section 3.2(c)(iii) hereof. Upon termination of the Executive's
employment with the Company by the Executive without Good Reason, the Loans
shall become immediately due and payable within thirty (30) days of the date of
such termination of employment.

                  4.7.     Other Benefits. The Executive shall be entitled to
four (4) weeks of paid vacation each calendar year during the Term of
Employment, to be taken at such times as the Executive and the Company shall
mutually determine and provided that no vacation time shall significantly
interfere with the duties required to be rendered by the Executive hereunder.
Any vacation time not taken by Executive during any calendar year may be carried
forward into any succeeding calendar year. The Executive shall receive such
additional benefits, if any, as the Board of the Company shall from time to time
determine.

<PAGE>   9

Section 5.5 by the Executive for Good Reason, the Company shall pay to the
Executive the same amounts, and shall continue or compensate for Benefits in the
same amounts, that would have been payable or provided by the Company to
Executive under Section 5.4 of this Agreement if the Term of Employment had been
terminated by the Company without Cause. In addition, if the termination of the
Term of Employment occurs after a Change in Control, and as a result of the
Change in Control, the Executive would be titled to a reduction in the option
price for any options granted to the Executive, or any cash payments from the
Company, (other than those provided under this Agreement) in addition to those
specified in Section 5.4, under any plan or program maintained by the Company
(the "Additional Benefits"), then the Company shall provide the Executive with
those Additional Benefits, if and only to the extent that such Additional
Benefits, when added to the amounts payable and the Benefits provided by the
Company to the Executive hereunder, will not constitute excess parachute
payments with the meaning of Section 280G of the Code. Upon any termination
effected and compensated pursuant to this Section 5.5(c), the Company shall have
no further liability hereunder (other than for (x) reimbursement for reasonable
business expenses incurred prior to the date of termination, subject, however,
to the provisions of Section 4., and (y) payment of compensation for unused
vacation days that have accumulated during the calendar year in which such
termination occurs).

                           d.       For purposes of this Agreement, "Good
Reason" shall mean (i) the assignment to the Executive of any duties
inconsistent in any respect with the Executive's position (including status,
offices, titles and reporting requirements), authority, duties or
responsibilities as contemplated by Section 1.2 of this Agreement, or any other
action by the Company which results in a diminution in such position,
authority, duties or responsibilities, excluding for this purpose an isolated,
insubstantial and inadvertent action not taken in bad faith and which is
remedied by the Company promptly after receipt of notice thereof given by the
Executive; (ii) any failure by the Company to comply with any of the provisions
of Article 3 of this Agreement, other than an isolated, insubstantial and

the occurrence of a Change in Control. For purposes of this Section 5.5(d), the
Executive acknowledges that the Company's holding company functions are
headquartered and centralized in Atlanta, Georgia. For purposes of this Section
5.5(d), any good faith determination of "Good Reason" made by the Executive
shall be conclusive; provided that the Executive shall not exercise his right to
terminate his employment or Good Reason without first giving sixty (60) days
written notice to the Chief Executive Officer of the factual basis constituting
Good Reason. The Company shall have the right to cure the problem(s) noted by
the Executive, before the Executive may terminate his employment for Good
Reason.

                           e.       For purposes of this Agreement, the term
"Change in Control" shall mean:

                           (i)      Approval by the shareholders of the Company
of (x) a reorganization, merger, consolidation or other form of corporate
transaction or series of transactions, in each case, with respect to which
persons who were the shareholders of the Company immediately prior to such
reorganization, merger or consolidation or other transaction do not, immediately
thereafter, own more than 50% of the combined voting power entitled to vote
generally in the election of directors of the reorganized, merged or
consolidated company's then outstanding voting securities, in substantially the
same proportions as their ownership immediately prior to such reorganization,
merger, consolidation or other transaction, or (y) a liquidation or dissolution
of the Company or (z) the sale of all or substantially all of the assets of the
Company (unless such reorganization, merger, consolidation or other corporate
transaction, liquidation, dissolution or sale is subsequently abandoned);

                           (ii)     A new Board member is elected without the
approval of at least two of the Individuals who, as of the Commencement Date of
this Agreement, constitute the Board (the "Incumbent Board"); or

                           (iii)    the acquisition (other than from the
Company) by any person, entity or "group", within the meaning of Section
13(d)(3) or 14(d)(2) of the Securities Exchange Act, of beneficial ownership
within the meaning of Rule 13-d promulgated under the Securities Exchange Act of
more than 50% of either the then outstanding shares of the Company's Common
Stock or the combined voting power of the Company's then outstanding voting
securities entitled to vote generally in the election of directors (hereinafter
referred to as the ownership of a "Controlling Interest") excluding, for this
purpose, any acquisitions by (1) the Company or its Subsidiaries, (2) any
person, entity or "group" that as of the Commencement Date of this Agreement
owns beneficial ownership (within the meaning of Rule 13d-3 promulgated under
the Securities Exchange Act) of a Controlling Interest or (3) any employee
benefit plan of the Company or its Subsidiaries;

                           (iv)     provided that, with respect to this Section
5.5(e), a Change in Control shall not be deemed to have occurred should any of
the contingencies referred to in this Section involve any of those companies,
persons or other legal entities with whom the Company is negotiating on or
before the Commencement Date and which are communicated, in writing, by the
Company to the Executive upon execution of this Agreement.

                  5.6.     Certain Additional Payments by the Company. Anything
in this Agreement to the contrary notwithstanding, in the event it shall be
determined that any payment, distribution or other action by the Company to or
for the benefit of the Executive (whether paid or payable or distributed or
distributable pursuant to the terms of this Agreement or otherwise, including
any additional payments required under this Section 5.6) (a "Payment") would be
subject to an excise tax imposed by Section 4999 of the Internal Revenue Code of
1986, as amended (the "Code"), or any interest or penalties are incurred by the
Executive with respect to any such excise tax (such excise tax, together with
any such interest and penalties, are hereinafter, collectively referred to as
the "Excise Tax"), the Company shall make a payment to the Executive (a
"Gross-Up Payment") in an amount such that after payment by the Executive of all
taxes (including any Excise Tax) imposed upon the Gross-Up Payment, the
Executive retains (or


                                       10
<PAGE>   11
has had paid to the Internal Revenue Service on his behalf) an amount of the
Gross-Up Payment equal to the sum of (x) the Excise Tax imposed upon the
Payments and (y) the product of any deductions disallowed because of the
inclusion of the Gross-Up Payment in the Executive's adjusted gross income and
the highest applicable marginal rate of federal income taxation for the calendar
year in which the Gross-Up Payment is to be made. For purposes of determining
the amount of the Gross-Up Payment, the Executive shall be deemed to (i) pay
federal income taxes at the highest marginal rates of federal income taxation
for the calendar year in which the Gross-Up Payment is to be made, and (ii) pay
applicable state and local income taxes at the highest marginal rate of taxation
for the calendar year in which the Gross-Up Payment is to be made, net of the
maximum reduction in federal income taxes which could be obtained from deduction
of such state and local taxes.

                  5.7.     Resignation. Upon any termination of employment
pursuant to this Article 5, the Executive shall be deemed to have resigned as an
officer, and if he or she was then serving as a director of the Company, as a
director, and if required by the Board, the Executive hereby agrees to
immediately execute a resignation letter to the Board.

                  5.8.     Survival. The provisions of this Article 5 shall
survive the termination of this Agreement, as applicable.

         6. Restrictive Covenants.

                  6.1.     Non-competition. In order to fully protect the
Company's Proprietary Information, at all times during the Restricted Period,
the Executive shall not, directly or indirectly, perform or provide managerial
or executive services on behalf of any person, entity or enterprise which is
engaged in, or plans to engage in, any business in the United States that
directly or indirectly competes with the Company's Business (for this purpose,
the "Company's Business" is the business of telephone and telecommunication
installation and service and the manufacture, sale and installation of highway
signs and traffic control products.) During the Executive's employment with the
Company, the Executive shall not, directly or indirectly, have any interest in
any business (other than the Company) that competes with the Company's Business,
provided that this provision shall not apply to the Executive's ownership or
acquisition, solely as an investment, of securities of any issuer that is
registered under Section 12(b) or 12(g) of the Securities Exchange Act of 1934,
as amended, and that are listed or admitted for trading on any United States
national securities exchange or that are quoted on the National Association of
Securities Dealers Automated Quotations System, or any similar system or
automated dissemination of quotations of securities prices in common use, so
long as the Executive does not control, acquire a controlling interest in or
become a member of a group which exercises direct or indirect control of, more
than five percent of any class of capital stock of such corporation. For
purposes of this Agreement the "Restricted Period" shall be the period during
which the Executive is employed by the Company and, if the Executive's
employment with the Company is either terminated by the Company without Cause
pursuant to Section 5.4, or by the Executive for Good Reason pursuant to Section
5.5c, and the Company has paid to the Executive all of amounts then payable to
the Executive pursuant to Sections 5.4 or 5.5c, as


                                       11
<PAGE>   12

applicable, the three (3) year period immediately following the termination of
the Executive's employment with the Company.

                  6.2.     Confidential Information. The Executive recognizes
and acknowledges that the Trade Secrets (as defined below) and Confidential
Information (as defined below), of the Company and all physical embodiments
thereof, as they may exist from time-to-time, collectively, the "Proprietary
Information" valuable, special and unique assets of the Company's Business. In
order to obtain and/or maintain access to such Proprietary Information, which
employee acknowledges is essential to the performance of his duties under this
Agreement, the Executive agrees that, except with respect to those duties
assigned to him by the Company, the Executive shall hold in confidence all
Proprietary Information and the Executive will not reproduce, use, distribute,
disclose, or otherwise misappropriate any Proprietary Information, in whole or
in part, and will take no action causing, or fail to take any action necessary
to prevent causing, any Proprietary Information to lose its character as
Proprietary Information, nor will the Executive make use of any such Information
for the Executive's own purposes or for the benefit of any person, business or
legal entity (except the Company) under any circumstances, except that the
Executive may disclose such Proprietary Information to the extent required by
law, provided that, prior to any such disclosure, the Company be provided an
opportunity to contest such disclosure.

                  For purposes of this Agreement, the term "Trade Secrets" means
information belonging to or licensed to the Company, regardless of form,
including, but not limited to, any technical or non-technical data, formula,
pattern, compilation, program, device, method, technique, drawing, financial,
marketing or other business plan, lists of actual or potential customers or
suppliers, or any other information similar to any of the foregoing, which
derives economic value, actual or potential, from not being generally known to,
and not being readily ascertainable by proper means by, other persons who can
derive economic value from its disclosure or use. The term "Confidential
Information" means any information belonging to or licensed to the Company,
regardless of form, other than Trade Secrets, which is valuable to the Company
and not generally known to competition of the Company.

                  The provisions of this Section 6.2 will apply to Trade Secrets
for as long as such information remains a Trade Secret and to Confidential
Information during the Executive's employment with the Company and for a period
of two (2) years following the termination of the Executive's employment with
the Company for whatever reason.

                  6.3.     Nonsolicitation of Employees and Customers. At all
times during the Restricted Period, as defined in Section 6.1 hereof, the
Executive shall not, directly or indirectly, for himself or for any other
person, firm, corporation, partnership, association or other entity (a) employ,
solicit, recruit or attempt to employ, solicit, or recruit any employee of the
Company to leave the Company's employment, or (b) solicit or attempt to solicit
any of the actual or targeted prospective customers or clients of the Company
with whom the Executive had material contact or about whom the Executive learned
Confidential Information on behalf of any person or entity in connection with
any business that competes with the Company's Business.

<PAGE>   13

                  6.4.     Ownership of Developments. All copyrights, patents,
trade secrets, or other intellectual property rights associated with any ideas,
concepts, techniques, inventions, processes, or works of authorship developed or
created by Executive during the course of performing work for the Company or its
client (collectively, the "Work Product") shall belong exclusively to the
Company and shall, to the extent possible, be considered a work made by the
Executive for hire for the Company within the meaning of Title 17 of the United
States Code. To the extent the Work Product may not be considered work made by
the Executive for hire for the Company, the Executive agrees to assign, and
automatically assign at the time of creation of the Work Product, without any
requirement of further consideration, any right, title, or interest the
Executive may have in such Work Product. Upon the request of the Company, the
Executive shall take such further actions, including execution and delivery of
instruments of conveyance, as may be appropriate to give full and proper effect
to such assignment.

                  6.5.     Books and Records. All books, records, and accounts
relating in any manner to the customers or clients of the Company, whether
prepared by the Executive or other-wise coming into the Executive's possession,
shall be the exclusive property of the Company and shall be returned immediately
to the Company on termination of the Executive's employment hereunder or on the
Company's request at any time.

                  6.6.     Definition of Company. Solely for purposes of this
Article 6, the term "Company" also shall include any existing or future
subsidiaries of the Company that are operating during the time periods described
herein and any other entities that directly or indirectly, through one or more
intermediaries, control, are controlled by or are under common control with the
Company during the periods described herein.

                  6.7.     Acknowledgment by Executive. The Executive
acknowledges and confirms that (a) the restrictive covenants contained in this
Article 6 are reasonably necessary to protect the legitimate business interests
of the Company, and (b) the restrictions contained in this Article 6 (including
without limitation the length of the term of the provisions of this Article 6)
are not overbroad, overlong, or unfair and are not the result of overreaching,
duress or coercion of any kind. The Executive further acknowledges and confirms
that his full, uninhibited and faithful observance of each of the covenants
contained in this Article 6 will not cause him any undue hardship, financial or
otherwise, and that enforcement of each of the covenants contained herein will
not impair his ability to obtain employment commensurate with his abilities and
on terms fully acceptable to him or otherwise to obtain income required for the
comfortable support of him and his family and the satisfaction of the needs of
his creditors. The Executive acknowledges and confirms that his special
knowledge of the business of the Company is such as would cause the Company
serious injury or loss if he were to use such ability and knowledge to the
benefit of a competitor or were to compete with the Company in violation of the
terms of this Article 6. The Executive further acknowledges that the
restrictions contained in this Article 6 are intended to be, and shall be, for
the benefit of and shall be enforceable by, the Company's successors and
assigns.

                  6.8.     Reformation by Court. In the event that a court of
competent jurisdiction shall determine that any provision of this Article 6 is
invalid or more restrictive than permitted


                                       13
<PAGE>   14

under the governing law of such jurisdiction, then only as to enforcement of
this Article 6 within the jurisdiction of such court, such provision shall be
interpreted and enforced as if it provided for the maximum restriction permitted
under such governing law.

                  6.9.     Extension of Time. If the Executive shall be in
violation of any provision of this Article 6, then each time limitation set
forth in this Article 6 shall be extended for a period of time equal to the
period of time during which such violation or violations occur. If the Company
seeks injunctive relief from such violation in any court, then the covenants set
forth in this Article 6 shall be extended for a period of time equal to the
pendency of such proceeding including all appeals by the Executive.

                  6.10.    Survival. The provisions of this Article 6 shall
survive the termination of this Agreement, as applicable.

         7.       Injunction. It is recognized and hereby acknowledged by the
parties hereto that a breach by the Executive of any of the covenant contained
in Article 6 of this Agreement will cause irreparable harm and damage to the
Company, the monetary amount of which may be virtually impossible to ascertain.
As a result, the Executive recognizes and hereby acknowledges that the Company
shall be entitled to an injunction from any court of competent jurisdiction
enjoining and restraining any violation of any or all of the covenants contained
in Article 6 of this Agreement by the Executive or any of his affiliates,
associates, partners or agents, either directly or indirectly, and that such
right to injunction shall be cumulative and in addition to whatever other
remedies the Company may possess.

         8.       Attorney's Fees. Nothing contained herein shall be construed
to prevent the Company or the Executive from seeking and recovering from the
other damages sustained by either or both of them as a result of its or his
breach of any term or provision of this Agreement. In the event that either
party hereto brings suit or the collection of any damages resulting from, or the
injunction of any action constituting, a breach of any of the terms or
provisions of this Agreement, then the party found to be at fault shall pay all
reasonable court costs and attorneys' fees of the other.

         9.       Assignment. Neither party shall have the right to assign or
delegate his rights or obligations hereunder, or any portion thereof, to any
other person.

         10.      Governing Law and Venue. This Agreement shall be governed by
and construed and enforced in accordance with the internal laws of the State of
Georgia. The venue for any action to enforce this Agreement shall be the state
or federal courts located within Fulton County, Georgia.

         11.      Entire Agreement. This Agreement constitutes the entire
agreement between the parties hereto with respect to the subject matter hereof
and, upon its effectiveness, shall supersede all prior agreements,
understandings and arrangements, both oral and written, between the Executive
and the Company (or any of its a affiliates) with respect to such subject
matter. This Agreement may not be modified in any way unless by a written
instrument signed by both the Company and the Executive.

         12.      Notices: All notices required or permitted to be given
hereunder shall be in writing and shall be personally delivered by courier, sent
by registered or certified mail, return receipt requested or sent by confirmed
facsimile transmission addressed as set forth herein. Notices personally
delivered, sent by facsimile or sent by overnight courier shall be deemed given
on the date of delivery and notices mailed in accordance with the foregoing
shall be deemed given upon the earlier of receipt by the addressee, as evidenced
by the return receipt thereof, or three (3) days after deposit in the U.S. mail.

         13.      Benefits; Binding Effect. This Agreement shall be for the
benefit of and binding upon the parties hereto and their respective heirs
personal representatives, legal representatives, successors and, where permitted
and applicable, assigns, including, without limitation, any successor to the
Company, whether by merger, consolidation, sale of stock, sale of assets or
otherwise.

         14.      Severability. The invalidity of an one or more of the words,
phrases, sentences, clauses, provisions, sections or articles contained in this
Agreement shall not affect the enforceability of the remaining portions of this
Agreement or any part thereof, all of which are inserted conditionally on their
being valid in law, and, in the event that anyone or more of the words, phrases,
sentences, clauses, provisions, sections or articles contained in this Agreement
shall be declared invalid, this Agreement shall be construed as if such invalid
word or words, phrase or phrases, sentence or sentences, clause or clauses,
provisions or provisions, section or sections or article or articles had not
been inserted. If such invalidity is caused by length of time or size of area,
or both, the otherwise invalid provision will be considered to be reduced to a
period or area which would cure such invalidity.

         15.      Waivers. The waiver by either party hereto of a breach or
violation of any term or provision of this Agreement shall not operate nor be
construed as a waiver of any subsequent breach or violation.

         16.      Damages. Nothing contained herein shall be construed to
prevent the Company or the Executive from seeking and recovering from the other
damages sustained by either or both of them as a result of its or his breach of
any term or provision of this Agreement. In the event that either party hereto
brings suit for the collection of any damages resulting from, or the injunction
of any action constituting, a breach of any of the terms or provisions of this
Agreement, then the party found to be at fault shall pay all reasonable court
costs and attorneys' fees of the other.

         17.      Section Headings. The article, section and paragraph headings
contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement.

         18.      No Third Party Beneficiary. Nothing expressed or implied in
this Agreement is intended, or shall be construed, to confer upon or give any
person other than the Company, the


                                       15
<PAGE>   16

parties hereto and their respective heirs, personal representatives, legal
representatives, successors and permitted assigns, any rights or remedies under
or by reason of this Agreement.

         19.      Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together shall constitute one and the same instrument and agreement.

         20.      Indemnification.

                           a.       Subject to limitations  imposed by law, the
Company shall indemnify and hold harmless the Executive to the fullest extent
permitted by law from and against any and all claims, damages, expenses
(including attorneys' fees), judgments, penalties, fines, settlements, and all
other liabilities incurred or paid by him in connection with the investigation,
defense, prosecution, settlement or appeal of any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative and to which the Executive was or is a party or is threatened to
be made a party by reason of the fact that the Executive is or was an officer,
employee or agent of the Company, or by reason of anything done or not done by
the Executive in any such capacity or capacities, provided that the Executive
acted in good faith, in a manner that was not grossly negligent or constituted
willful misconduct and in a manner he reasonably believed to be in or not
opposed to the best interests of the Company, and, with respect to any criminal
action or proceeding, had no reasonable cause to believe his conduct was
unlawful. The Company also shall pay any and all expenses (including attorney's
fees) incurred by the Executive as a result of the Executive being called as a
witness in connection with any matter involving the Company and/or any of its
officers or directors.

                           b.       The Company shall pay any expenses
(including attorneys' fees), judgments, penalties, fines, settlements, and other
liabilities incurred by the Executive in investigating, defending, settling or
appealing any action, suit or proceeding described in this Section 20 in advance
of the final disposition of such action, suit or proceeding. The Company shall
promptly pay the amount of such expenses to the Executive, but in no event later
than 10 days following the Executive's delivery to the Company of a written
request for an advance pursuant to this Section 20, together with a reasonable
accounting of such expenses.

                           c.       The Executive hereby undertakes and agrees
to repay to the Company any advances made pursuant to this Section 20 if and to
the extent that it shall ultimately be found that the Executive is not entitled
to be indemnified by the Company for such amounts.

                           d.       The Company shall make the advances
contemplated by this Section 20 regardless of the Executive's financial ability
to make repayment, and regardless whether indemnification of the Indemnitee by
the Company will ultimately be required. Any advances and undertakings to repay
pursuant to this Section 20 shall be unsecured and interest-free.

                           e.       The provisions of this Section 20 shall
survive the termination of this Agreement.
