In the event that this Agreement has not been earlier terminated in accordance

by, under common control with or otherwise affiliated with, the Company (any
such entity hereinafter referred to as an "Affiliate"), and to accept such
office or position with any Affiliate as the Board may reasonably require,
including but not limited to service as an officer and/or director of an

                  (b) PERFORMANCE OF SERVICES. During and throughout the

and affairs of the Company and the performance of his duties under this
Agreement. Employee shall not, directly or indirectly, render any services of a
business, commercial or professional nature to any person or organization

<PAGE>

provisions this Section 3(b) shall not preclude Employee from devoting time,
ability, energy and attention outside normal business hours throughout the
Employment Term to reasonable participation in community, civic, charitable or
similar organizations, or the pursuit of personal legal and financial affairs
which do not interfere or conflict with the performance of Employee's duties
hereunder and are not adverse to the business or best interests of the Company.

                  (c) PLACE OF EMPLOYMENT. Employee shall perform his services
hereunder at the Company's principal executive offices in Melbourne, Florida, or
at such other location as mutually agreed with the Board; provided, however,

the Company hereunder, the Company shall pay and provide or cause to be provided
to Employee the following:

                  (a) BASE SALARY. The Company shall pay Employee a base salary
equal to $175,000 per year (the "Base Salary"), payable in approximately equal
installments in accordance with the Company's customary payroll practices. In
the event the Employment Term is extended beyond the initial one year term, then
Employee's Base Salary may be reviewed by or under the authority of the Board
and may be increased at the sole discretion of the Board or its designee
(although the Board has no obligation to do so) based upon whatever factors the
Board or its designee deems appropriate including, but not limited to,
Employee's individual performance, the overall performance, profitability and
prospects of the Company and prevailing economic and industry factors.

                  (b) BONUSES. So long as he remains employed with the Company,
Employee shall be entitled to receive the following bonuses:

                    (i) CASH FLOW BONUS. Employee shall be entitled to receive a
bonus in the amount of 7% of the Company's "Cash Flow from Operations" (the
"Cash Flow Bonus") during the Employment Term on the basis of periods (each, a
"Cash Flow Bonus Period"), the first Cash Flow Bonus Period commencing on July
1, 2002 and ending on the earlier of December 31, 2002 or the last day of the
month in which Employee's employment hereunder is terminated, and each
subsequent Cash Flow Bonus Period, if any, commencing on January 1 of the
subsequent year and ending on the earlier of December 31 of that year or on the
last day of the month in which Employee's employment hereunder is terminated, on
the following terms and conditions:

                                    (A) The Company's "Cash Flow from
Operations" for any Cash Flow Bonus Period shall be an amount equal to the
Company's net income (loss) before taxes, depreciation and amortization, but
after interest, during such Cash Flow Bonus Period, determined in accordance
with generally accepted accounting principles consistently applied, adjusted to
exclude (I) all items of income, gain, loss or expense during such Cash Flow
Bonus Period determined by the Board to be extraordinary or unusual in nature
and not incurred or realized in the ordinary course of business, whether or not
such items would otherwise be considered to be extraordinary or unusual in
accordance with generally accepted accounting principles, and (II) any profit or
loss attributable to the business operations of any entity acquired by the
Company during such Cash Flow Bonus Period, and shall be determined by the Board
in its sole discretion based upon the Company's financial statements for such
Cash Flow Bonus Period.

                                    (B) The Company shall pay any Cash Flow
Bonus within 90 days after the expiration of a Cash Flow Bonus Period. In the
event that the Company's Cash Flow from Operations during any Cash Flow Bonus
Period is negative, then Employee shall not be entitled to any Cash Flow Bonus
for such Cash Flow Bonus Period under any circumstances.

                                    (C) In order to be entitled to receive the
Cash Flow Bonus for any Cash Flow Bonus Period, Employee must not have been
terminated by the Company for "Cause" or have voluntarily terminated his
employment with the Company during such Cash Flow Bonus Period.

Employee shall also be involved in the Company's allocation of up to an
additional 3% of the Company's "Cash Flow from Operations" to other employees of
the Company.

                    (ii) GENERAL BONUS PROGRAM.  If the Company shall adopt a
bonus program or any other form of profit-sharing participation for senior
executive officers of the Company, Employee shall be eligible to participate in
such program in a manner and capacity commensurate with his position and duties.

                  (c) METRETEK STOCK OPTIONS. Because the Company is a
subsidiary of Metretek Technologies, Inc., a Delaware corporation ("Metretek"),
employees of the Company are eligible to receive stock options under Metretek's
1998 Stock Incentive Plan. In consideration in part for inducing Employee to
enter into this Agreement and for his services hereunder, the Company shall use
its best efforts to cause Metretek to grant to Employee five year non-qualified
stock options (the "Metretek Stock Options") to purchase 100,000 shares of
Common Stock, par value $.01 per share ("Metretek Shares"), of Metretek, at an
exercise price of $1.50 per share. The Metretek Stock Options shall vest in four
equal quarterly installments, provided Employee remains employed with the
Company on such dates and has not submitted his notice of termination prior to
such dates: (i) 25,000 Metretek Shares on September 30, 2002, (ii) 25,000
Metretek Shares on December 31, 2002, (iii) 25,000 Metretek Shares on March 31,
2003, and (iv) 25,000 Metretek Shares on June 23, 2003 (the "Vesting Dates"). In
the event Employee is terminated for "Cause" or provides written notice of his
voluntary termination on or prior to any Vesting Date, then no further Metretek
Stock Options shall thereafter vest, and all unvested options shall immediately
expire and be forfeited, but all previously vested Metretek Stock Options shall
remain exercisable until the fifth anniversary of the date hereof. Except as
expressly provided herein, all Metretek Stock Options shall be subject to the
terms and conditions of the Metretek 1998 Stock Incentive Plan, and of the
customary form of stock option agreement used thereunder.

                  (d) MCM SHARES. In consideration in part for inducing Employee
to enter into this Agreement and to perform his services hereunder, after MCM is
organized as a Florida corporation and a subsidiary of the Company, the Company
shall cause MCM to issue to Employee shares of common stock of MCM (the "MCM
Shares") constituting in the aggregate 8% of the issued and outstanding MCM
Shares as of the date of organization, in four equal quarterly installments,
with 25% of such MCM Shares being issued on each Vesting Date. In the event
Employee is terminated for "Cause" or provides written notice of his voluntary
termination on or prior to any Vesting Date, then no further MCM Shares shall be
issued to Employee after such date. All MCM Shares shall be issued subject to
the terms and conditions of a Shareholders' Agreement, in substantially the form
attached hereto as Exhibit A, which contains certain rights and restrictions on
the MCM Shares. Employee shall also be involved in the Company's allocation of
up to an additional 7% of the issued and outstanding MCM Shares as of the date
hereof to other employees of the Company.

                  (e) INCENTIVE COMPENSATION UPON SALE. In the event of a "Sale"
(as defined below) of the Company, Employee shall be entitled to receive
incentive compensation (the "Incentive Compensation") in an amount computed in
accordance with this Section 3(e).

                           (i) The amount of the Incentive Compensation will be
based upon the "Net Proceeds" attributable to the "Core Business" received by
the Company from a "Sale" (as such terms are defined in this Section 3(e)), in
accordance with the schedule attached hereto as Exhibit B. For purposes of the
computation of the amount of the Incentive Compensation, the "Net Proceeds"
shall mean the amount of proceeds received by the Company attributable to the
assets, business, rights, interests and goodwill of the Company (the "Core
Business") excluding the assets, business, rights, interests and goodwill of MCM
(the "MCM Business"), net of (A) all transaction costs and expenses incurred by
the Company in connection with the Sale, and (B) repayment of all debts,
liabilities and other obligations of the Company not assumed by the purchaser or
successor in the Sale. In the event of a Sale involving the Core Business and
the MCM Business in which the Net Proceeds attributable to the Core Business is
not separated from the MCM Business and is not allocated in connection with the
Sale or in the documentation relating to the Sale, then the Net Proceeds
applicable to the computation of the Incentive Compensation referred to in this
Section 3(e) shall be determined based upon the allocation of the aggregate net
proceeds received by the Company in connection with such Sale by the Board of
Directors of Metretek (the "Metretek Board") based upon its good faith
determination of the relative values of the MCM Business and the Core Business,
which determination shall be deemed conclusive and binding on the parties hereto
for purposes of determining the amount of the Incentive Compensation.

                           (ii) The Company shall pay the Incentive
Compensation earned by the Employee from a Sale on the same business day as the
Company receives the proceeds of the Sale; provided, however, that in the event
all or any portion of the proceeds of the Sale are received by the Company over
an extended period of time (such as pursuant to an escrow, earn-out or other
contingent payment schedule), then the Company shall pay such portion of the
Incentive Compensation attributable to such deferred proceeds within three (3)
business days of the Company's receipt of such deferred proceeds.

                           (iii) In the event that all or any portion of the
proceeds received by the Company from a Sale consist of securities, property or
other non-cash assets, then the Incentive Compensation to be paid by the Company
to Employee hereunder shall be in the same proportion and consist of the same
type of non-cash proceeds as the Company shall receive, to the extent reasonably
practicable; provided, however, that if such non-cash proceeds from such Sale
are not

                                       3
<PAGE>

separable by the Company or transferable to Employee, then the Board shall use
its best efforts to provide equivalent value (based on the fair market value of
the non-cash proceeds received by the Company on the date of receipt) to the
Employee.

                           (iv) For purposes hereof, a "Sale" of the Company
shall mean and include only the following:

                                    (A)     the sale of all or substantially
all of the assets of the Company;

                                    (B)     a transaction involving the merger
or consolidation or combination of the Company with and into another Entity, in
which transaction the Company is not the survivor;

                                    (C)     the sale of 75% or more of the then
outstanding shares of the Company;

in each case involving a purchaser that is not Metretek, a subsidiary of the
Company or another affiliate of the Company.

                           (v)      Employee shall be entitled to receive the
Incentive Compensation only if both of the following events occur:

                                    (A)     the Sale is consummated by the
Company on or prior to the date Employee's employment with the Company is
terminated for any reason, or within 60 days thereafter if the transaction
commenced prior to the date of termination and Employee's employment was not
terminated voluntarily by Employee or with "Cause" by the Company; and

                                    (B)     Employee waives any and all rights
to the Severance Payment (as defined below).

                           (vi)  In the event, prior to the date Employee's
employment with the Company is terminated for any reason, the Company receives a
bona fide offer in writing, which includes the purchase price or other form of
consideration in a calculable structure, from a financially capable Person not
affiliated or associated with Employee, to enter into a transaction, the
consummation of which would constitute a Sale hereunder, and the Company rejects
such bona fide offer, then, if Employee waives any and all rights to the
Severance Payment, Employee shall be entitled to receive from the Company that
number of shares of common stock, par value $___ per share, of the Company
("Company Shares") that constitutes a percentage of the total issued and
outstanding Company Shares equal to the percentage that the amount of the
Incentive Compensation Employee would have received if the Sale had been
consummated in accordance with the terms of the bona fide offer would have
constituted of the total amount of the net proceeds the Company would have
received if the Sale had been consummated in accordance with the terms of bona
fide offer. All Company Shares shall be issued subject to the terms and
conditions of a Shareholders' Agreement, in substantially the form attached
hereto as Exhibit C, which contains certain rights and restrictions on the
Company Shares.

                  (f) EMPLOYEE BENEFIT PLANS. Employee shall be entitled to
participate in all pension, 401(k), retirement, life, disability and health
insurance, hospitalization, major medical and other the employee benefit plans
and arrangements, if any (as in effect and as amended from time to time), to the
extent that his position, tenure, salary, age, health and other qualifications
make his eligible to participate, generally made available by the Company to
comparable level employees, subject to and on a basis consistent with the terms,
rules and regulations, conditions and overall administration of such plans and
arrangements. Notwithstanding the foregoing sentence, the Company may
discontinue at any time any such the employee benefit plan or arrangement, to
the extent permitted by the terms of such plans or arrangements, and shall not
be required to compensate Employee for the elimination of any such employee
benefit plans or arrangements.

                  (g) EXPENSES. The Company shall, upon presentment by Employee
of appropriate receipts and vouchers therefor, reimburse Employee for all
reasonable, ordinary and necessary out-of-pocket business expenses incurred by
Employee in connection with the performance of his duties under this Agreement,
provided that such expenses are incurred and accounted for in accordance with
and subject to the normal policies and procedures of the Company.

                  (h) VACATION. Employee shall be entitled to three (3) weeks
paid vacation time during the first twelve (12) month period of the Employment
Term and four (4) weeks paid vacation time during each subsequent twelve (12)
month periods of the Employment Term, which vacation time shall vest pro rata
over the course of each such twelve (12) month term and shall be scheduled and
otherwise taken in accordance with the policies of the Company applicable to

         SECTION 5.   TERMINATION OF EMPLOYMENT.   Notwithstanding the
provisions of Section 2 hereof, the Employment Term and Employee's employment
hereunder shall terminate as follows:

right, in its sole discretion, to terminate Employee's employment hereunder at
any time 90 days after the giving of written notice of such termination to
Employee (or at such later date as the notice provides). In such event, Employee

                           (i)      COMPETITION WITH THE COMPANY.  For purposes
of this Agreement, (A) the phrase "in competition with the Company" shall be
deemed to include competition with the Company and its subsidiaries and
Affiliates, or their respective successors or assigns, or the businesses of any
of them, and (B) a business shall be deemed to be in competition with the
Company if it is engaged in any business activity or has products or services
that are the same or similar to the business activities, products or services of
the Company during the Employment Term. Notwithstanding the foregoing, nothing
herein contained shall prevent Employee from acquiring and holding for
investment up to two percent (2%) of any class of securities of any corporation,
if such securities are listed or traded on a national securities exchange or the
Nasdaq Stock Market or in the over-the-counter market.

                           (ii)     INTERPRETATION OF COVENANT.  The parties
hereto acknowledge and agree that the duration and area for which the covenant
not to compete set forth in this Section 6(a) is to be effective are fair and
reasonable and are reasonably necessary for the protection of the Company and
its business and good will, and Employee hereby waives any objections to or
defenses in respect thereof. In the event that any court determines that any
portion of the time period or the area, or both of them, are unreasonable,
arbitrary or against public policy, and that such covenant is to such extent
unenforceable, illegal or invalid, the parties hereto agree that this Section
6(a) shall be deemed amended to delete therefrom such provisions or portions
adjudicated to be unenforceable, illegal or invalid so that the covenant shall
remain in full force and effect for the greatest time period and in the greatest
geographical area that would render it enforceable, legal and valid. The parties
intend that the covenant set forth in the Section 6(a) shall be deemed to be a
series of separate covenants, one for each and every county of each and every
state of the United States of America and one for each and every political
subdivision of each and every other country where the covenant is intended to be
effective and is not proscribed by law.

                  (b)      COVENANT REGARDING DISCLOSURE OR USE OF CONFIDENTIAL
INFORMATION.

                           (i)      Employee acknowledges that during the
Employment Term and as a result of his employment by the Company, he will learn,
obtain and have access to confidential and proprietary information regarding the
business and affairs of the Company and its Affiliates. Employee hereby agrees
that during the Employment Term and for a period of two (2) years thereafter, he
shall keep strictly confidential and hold in confidence all Confidential
Information (as defined below), and shall not, directly or indirectly, use any
Confidential Information for Employee's own benefit or for the benefit of any
other Person or divulge, disclose, communicate or otherwise reveal any
Confidential Information to any Person in any manner whatsoever, other than to
the directors, employees and agents of the Company, and then only in the course
of the Company's affairs to the extent necessary for them to perform services to
and responsibilities on behalf of the Company.

                           (ii)     As used herein, "Confidential Information"
means any and all information, however documented, which is confidential
property or otherwise non-public, related to the business and affairs of the
Company and its Affiliates, including, but not limited to, their assets,
properties, operations, finances, practices, procedures, policies, methods,
contracts, agreements and arrangements, lending policies, pricing policies,
price lists, financial plans, business plans, financial information, financial
projections, budgets, marketing strategies and techniques; the identity and
location of all past, present and prospective customers, suppliers, affiliates,
debtors, creditors, lenders, employees, consultants, advisors, agents,
distributors, wholesalers, clients and others who have dealings with the
Company; trade secrets, processes, photographs, graphics, product
specifications, formulas, compositions, samples, inventions, ideas, research and
development; patents, patent applications; copyrights and copyright applications
(in any such case, whether registered or to be registered in the United States
or any foreign country) applied for, issued to or owned by the Company; any and
all processes, computer programs and software (including object code and source
codes, database, technologies, engineering or technical data, drawings, sketches
or designs, manufacturing or distribution methods or techniques; and any other
information known to Employee to be confidential, proprietary, secret or
otherwise non-public information.

                           (iii)    Employee hereby acknowledges and agrees
that, as between the Company and Employee, all of the Confidential Information,
however documented, whether or not developed, created or modified by Employee,
is the exclusive property of the Company.

                           (iv)     Upon the termination or expiration of the
Employment Term, Employee shall leave with or return to the Company, without
making or retaining any copies, or other records of, all Confidential
Information including all copies, summaries, abstracts thereof and all
memoranda, notes, records, reports, books, letters, customer lists, manuals and
other writings or documents whatsoever pertaining thereto. Notwithstanding the
foregoing, as used herein "Confidential Information" does not mean or include
any information that is generally available to the public other than as a result
of a direct or indirect disclosure by Employee.

                  (c) COVENANTS REGARDING BUSINESS RELATIONSHIPS. Employee
agrees that during and throughout the Employment Term and the Restricted Period,
except when acting on behalf of the Company, he shall not, directly or
indirectly, (i) employ, solicit, induce, engage or cause any director, officer,
employee, independent contractor, consultant, salesman or other agent of the
Company (whether now or hereafter engaged by the Company) to (A) terminate his
employment or engagement with the Company, (B) accept employment or engagement
or otherwise render services to any other Person or business (wherever located,
and regardless of type of business conducted), or (C) interfere with the
business of the Company; or (ii) solicit any clients or customers of the Company
or interfere in any business relationship between the Company and any other
person, firm or entity, including any person who was at any time an employee,
consultant, contractor, advisor, supplier, lender or customer of the Company.
Employee shall not, at any time during or after the Employment Term, disparage
the business reputation of the Company or any of its shareholders, directors,
officers, employees or agents or take actions that are harmful to the Company's
good will with others.

                  (d) INTELLECTUAL PROPERTY. During and throughout the
Employment Term and the Restricted Period, Employee agrees to disclose to the
Company any and all ideas, improvements, techniques, modifications, processes,
inventions, developments, discoveries, trade secrets, trademarks, service marks,
copy rights, trade names, business plans and any work of authorship
("Intellectual Property") developed, conceived, created, made, devised,
discovered, acquired or acquired knowledge of, by Employee during the Employment
Period, either by himself or in conjunction with any other person, which relates
in any way, directly or indirectly, or may be useful in any manner in the
business of the Company or its Affiliates, and any such item that is based upon
or utilizes Confidential Information, whether or not the Company or its
Affiliates obtains a patent, trademark, service mark or copyright thereon.
Employee hereby agrees that the Intellectual Property shall become and remain
the sole and exclusive property of the Company. Employee hereby acknowledges
that all of Employee's writing, works of authorship and other Intellectual
Property are works made for hire and the property of the Company, including
patents, trademarks, service marks, copyrights and other intellectual property
rights pertaining thereto. Employee shall, at the request and cost of the
Company or any of its Affiliates, render assistance as the Company deems
necessary or desirable to secure, prosecute and/or defend the rights thereto by
patent, trademark, service mark, copyright to otherwise to the Company or its
Affiliates, including without limitation the assignment, transfer and conveyance
to the Company or its Affiliates of all of Employee's right, title and interest
in and to the Intellectual Property.

                  (e) EMPLOYEE'S ACKNOWLEDGMENT. The Company spends considerable
amounts of time, money and effort in developing and maintaining good will in its
industry. Employee agrees the covenants contained within this Section 6, (i) are
reasonable and necessary in all respects to protect the goodwill, trade secrets,
confidential information, and business interests of the Company; (ii) are not
oppressive to Employee; (iii) do not impose any greater restraint on Employee
than is reasonably necessary to protect the goodwill, trade secrets,
confidential information and legitimate business interests of the Company; and
(iv) will not, upon the termination, of Employee's employment with the Company
for any reason whatsoever, cause Employee to be unable to earn a living that is
suitable and acceptable to Employee.

                  (f) EQUITABLE RELIEF. Employee hereby acknowledges and agrees
that his services to be rendered to the Company hereunder and his obligations
contained in this Section 6 are of special, unique and personal character which
gives them a peculiar value to the Company, that the Company cannot be
reasonably or adequately compensated in money damages in an action at law in the
event Employee breaches any obligations under this Section 6, and that the
provisions of this Section 6 are reasonable and necessary to protect the
business of the Company. Employee therefore expressly agrees that, in addition
to any other rights or remedies which the Company may have at law or in equity
or by reason of any other agreement, the Company shall be entitled to injunctive
and other equitable relief in the form of temporary, preliminary and permanent
injunctions without posting bond or other security in the event of any actual or
threatened breach of any such obligation by Employee and without the necessity
of proving actual damages, and to discontinue any salary, bonus, benefits and/or
insurance continuation provided hereunder. Nothing in this Agreement shall be
construed to prohibit the Company from pursuing any other remedy, and Employee
agrees that all remedies of the Company are cumulative.

                  (g) NATURE OF COVENANTS. Employee's covenants in Section 6
hereof are independent covenants, and the existence of any claim by Employee
against the Company under this Agreement or otherwise will not excuse Employee's
breach or waive Employee's obligation to perform, any covenant in this Section
6. If Employee's employment hereunder terminates for any reason, or the
Employment Term expires, this Section 6, and the other terms and conditions of
this Agreement necessary or appropriate to enforce the covenants of Employee in
Section 6, shall survive and remain in full force and effect.

                  SECTION 7. REPRESENTATIONS AND WARRANTIES OF EMPLOYEE.
Employee represents and warrants to the Company that (a) Employee is not a party
to or otherwise bound by any employment, consulting, confidentiality,
non-competition, proprietary rights or other similar agreement, obligation,
covenant or arrangement with any other person or entity that remains in effect
on the date hereof, and no person or entity has made any allegation or claim,
orally or in writing, to the



                                       8
<PAGE>

contrary, (b) Employee is under no oral or written contractual or other
restriction, covenant, arrangement or obligation that is or could be breached
by, or is or could be in conflict or inconsistent with, his employment by the
Company or the performance of his duties to the Company, and (c) Employee is
under no physical or mental disability or incapacity that would hinder the
performance of his duties under this Agreement.

         SECTION 8. CONSOLIDATION, MERGER OR SALE OF ASSETS. Nothing in this
Agreement shall preclude the Company from consolidating with, merging into, or
transferring all or substantially all of its assets to another entity which
assumes all of the Company's obligations and undertakings hereunder. Upon such a
consolidation, merger or transfer of assets, the term "Company" as used herein
shall mean such other entity, and this Agreement shall continue in full force
and effect.

         SECTION 9. EMPLOYEE ACKNOWLEDGMENT; COUNSEL. Employee acknowledges by
executing this Agreement and delivering it to the Company that (i) he has read
all of the terms and conditions hereof, including his obligations, covenants,
representations and warranties to the Company; (ii) the covenants of Employee in
Section 6 hereof are essential elements of this Agreement, and the Company would
not have entered into this Agreement without Employee's agreement to comply with
such covenants; (iii) each and every term, covenant and restriction is
reasonable and necessary for the proper protection of the Company's business;
and (iv) he has been advised by the Company that he should consult with
independent counsel of his choice and have such counsel review this Agreement
and render advice thereon to Employee, and Employee has either done so or
voluntarily elected not to do so.

         SECTION 10. TAXES. Employee shall be responsible for any and all taxes
on all compensation he receives from the Company. All payments required to be
made by the Company hereunder to Employee shall be subject to withholding of
such amounts relating to taxes as the Company may reasonably determine it should
withhold pursuant to any applicable federal, state or local law or regulation.
In lieu of withholding such amounts, in whole or in part, the Company may, in
its sole discretion, accept other provision for payment of taxes, provided it is
satisfied that all requirements of law affecting its responsibilities to
withhold such taxes have been satisfied.

         SECTION 11. NO ATTACHMENT. Except as required by law, no right to
receive payment under this Agreement shall be subject to anticipation,
commutation, alienation, sale, assignment, encumbrance, charge, pledge or
hypothecation or to execution, attachment, levy, or similar process of
assignment by operation of law, and any attempt, voluntary or involuntary, to
effect any such action shall be null, void and of no effect.

         SECTION 12. ARBITRATION. Any dispute, controversy or claim arises out
of, under or in connection with, or otherwise relating to, this Agreement (other
than the Company's rights under Section 6) (a "Dispute"), including but not
limited to the parties' rights and obligations hereunder, or any actual or
alleged breach hereof, shall be determined and settled by binding arbitration in
Florida in accordance with the rules of the commercial rules and procedures of
the American Arbitration Association, as amended by this Agreement. Promptly
after a Dispute arises, the parties agree to make a good faith effort to select
one mutually agreeable arbitrator. If the parties are unable to reach agreement
on an arbitrator within thirty (30) days after the Dispute is submitted to
arbitration, one arbitrator shall be selected in accordance with the commercial
rules and procedures of the American Arbitration Association. Any determination,
resolution or award made by the arbitrators shall specify the findings of fact
of the arbitrators and the reasons for the determination, resolution or award,
and such determination, resolution or award shall be final and binding. If the
parties hereto mutually agree to a resolution of any Dispute prior to the
arbitrators' decision, the agreement of the parties shall resolve the Dispute.
The party prevailing in any arbitration, as determined by the arbitrator, shall
be entitled to an award of all of its out-of-pocket costs and expenses incurred
in connection with the Dispute, including but not limited to reasonable
attorneys' fees, court costs and expert fees. An arbitration award or decision
may be entered by any court of competent jurisdiction, or application may be
made to such a court for judicial acceptance of the award or decision and any
appropriate order, including enforcement. The parties hereby consent to the
submission of any Dispute for settlement by binding arbitration in accordance
with this Section 12 and agrees to carry out without delay the provisions of any
arbitration award, decision or resolution.

         SECTION 13. GENERAL PROVISIONS.

                  (a) GOVERNING LAW.   This Agreement shall in all
respects be governed by, and construed in accordance with, the internal
substantive laws of the State of Florida, without giving effect to any conflict
or choice of law principles or rules.

obligations or duties hereunder, may be assigned or delegated by either party
hereto without the prior written consent of the other party hereto; provided,
however, that this Agreement shall inure to the benefit of and be binding upon
the successors and assigns of the Company upon any sale of all or substantially
all of the Company's stock or assets, or upon any merger, consolidation or
reorganization of the Company with or into any other Person, so long as such
successors or assigns assume all of the Company's obligations hereunder. As used

successor or assign of the Company referred to in the preceding sentence.
