                              WITH CARL J. JOHNSON

     This Amendment is entered into between Gum Tech International, Inc.
("Company") and Carl J. Johnson ("Executive") as of the 7th day of February,
2002.

     WHEREAS, the Company and the Executive have previously entered into an
Employment Agreement dated July 1, 2001 ("Agreement");

     WHEREAS, the parties desire to amend the Agreement to provide the Executive
with certain additional benefits.

     RESOLVED, that the parties hereby amend the Agreement as follows:

     1. Section 1.2(a) of the Agreement is hereby amended and restated as
follows:

          (a) Executive will serve as President and Chief Executive Officer of
     the Company, reporting directly to the Board of Directors of the Company.
     Executive agrees to perform services not inconsistent with these positions
     as shall from time to time be assigned to Executive by the Board.

     2. Section 2.2 of the Agreement is hereby amended and restated as follows:

          An annual bonus, beginning with the first year of employment, will be
     $112,500.00, based on meeting specified goals. After the first year of
     employment, the annual bonus target will be equal to at least one-half of
     Executive's Base Salary for the applicable year, based on meeting specified
     goals. The goal measurements will be based on 30% revenue, 40% net earnings
     and 30% business plans/strategies. The Board, or a committee thereof, will
     establish in each fiscal year during the term hereof an executive goal
     measurement plan. Any bonus under any such plan is referred to herein as
     the "Annual Incentive Bonus." This Annual Incentive Bonus shall be paid
     within ninety (90) days of the end of the year for which it is calculated.
     For the period July 1, 2001 through December 31, 2001, Executive shall be
     paid a pro rata Annual Incentive Bonus. After December 31, 2001,
     Executive's Annual Incentive Bonus will be calculated on a calendar year
     basis. For the period January 1, 2004 through June 30, 2004, Executive
     shall be paid a pro rata Annual Incentive Bonus.

     3. Section 2.4 of the Agreement is hereby amended by adding the following
(d) to the end thereof:

          (d) LIFE INSURANCE AND DISABILITY INSURANCE. In addition to other
     insurance benefits provided to Executive pursuant to this Agreement, the
     Company will provide Executive, at the Company's cost, life insurance and
     disability insurance coverage in amounts and at levels agreed upon between
     the parties. Once these amounts and levels have been determined, this
     coverage will not be modified or terminated without the signed, written
     consent of both parties.
<PAGE>
     4. Section 2.5 of the Agreement is amended and restated in its entirety as
follows:

          2.5 RELOCATION EXPENSES. Executive will receive up to $50,000.00 for
     relocation expenses from the Grand Rapids, Michigan area to a location
     designated by the Company by December 31, 2001. The Company will reimburse
     Executive for reasonable travel and temporary living expenses in the
     Phoenix, Arizona area until a determination has been made regarding the
     place to be designated by the Company for Executive's permanent relocation.
     Also, in the event that Executive's current residence is not sold within 90
     days of determination by the Company that Executive should permanently
     relocate from the Grand Rapids, Michigan area, the Company guarantees the
     purchase of the residence at the middle price of three (3) appraisals that
     Executive must obtain, or, protection for the sale of the residence up to
     $35,000.00 from the middle appraisal price. Any relocation requirement by
     the Company shall be within the continental United States. Any amounts paid
     to Executive pursuant to this Article 2.5 shall be increased to pay for any
     tax liability incurred by Executive as a result of the payment of these
     funds.

     5. All other portions of the Agreement shall remain the same and continue
in full force and effect.

                                        Gum Tech International, Inc.

In the event of termination for cause, the Company shall be obligated to pay
Employee only the minimum base salary due him through the date of termination.
The written notice shall state the cause for termination. Cause shall include

shall continue to pay to Employee his minimum base salary in effect at the time
of termination for a period of one year following the date of termination, at
the time and in the manner dictated by the Company's standard payroll policies.
Should such termination occur as a result of a change in control, the Company
shall also pay Employee a pro-rata share of his bonus at the time of
termination.

          (c) DISABILITY. If during the term of this Agreement, Employee fails
to perform his duties hereunder on account of illness or other incapacity for a
period of 45 consecutive days, or for 60 days during any six-month period, the

     7. CONFIDENTIAL INFORMATION. Employee acknowledges that Employee may
receive, or contribute to the production of, Confidential Information. For
purposes of this Agreement, Employee agrees that "Confidential Information"
shall mean any and all information or material proprietary to the Company or
designated as Confidential Information by the Company and not generally known by
non-Company personnel, which Employee develops or of or to which Employee may
obtain knowledge or access through or as a result of Employee's relationship
with the Company (including information conceived, originated, discovered or
developed in whole or in part by Employee). Confidential Information includes,
but is not limited to, the following types of information and other information
of a similar nature (whether or not reduced to writing) related to the Company's
business: discoveries, inventions, ideas, concepts, research, development,
processes, procedures, "know-how", formulae, marketing or manufacturing
techniques and materials, marketing and development plans, business plans,
customer names and other information related to customers, price lists, pricing
policies, methods of operation, financial information, employee compensation,
and computer programs and systems. Confidential Information also includes any
information described above which the Company obtains from another party and
which the Company treats as proprietary or designates as Confidential
Information, whether or not owned by or developed by the Company, including
Confidential Information acquired by the Company from any of its affiliates.
Employee acknowledges that the Confidential Information derives independent
economic value, actual or potential, from not being generally known to, and not
being readily ascertainable by proper means by, other persons who can obtain
economic value from its disclosure or use. Information publicly known without
breach of this Agreement that is generally employed by the trade at or after the
time Employee first learns of such information, or generic information or
knowledge which Employee would have learned in the course of similar employment
or work elsewhere in the trade, shall not be deemed part of the Confidential
Information. Employee further agrees:

          a. To furnish the Company on demand, at any time during or after
employment, a complete list of the names and addresses of all present, former
and potential suppliers, financing sources, clients, customers and other
contacts gained while an employee of the Company in Employee's possession,
whether or not in the possession or within the knowledge of the Company.

          b. That all notes, memoranda, electronic storage, documentation and
records in any way incorporating or reflecting any Confidential Information
shall belong exclusively to the Company, and Employee agrees to turn over all
copies of such materials in Employee's control to the Company upon request or
upon termination of Employee's employment with the Company.

          c. That while employed by the Company and thereafter Employee will
hold in confidence and not directly or indirectly reveal, report, publish,
disclose or transfer any of the Confidential Information to any person or
entity, or utilize any of the Confidential Information for any purpose, except
in the course of Employee's work for the Company.

                                       3
<PAGE>
          d. That any idea in whole or in part conceived of or made by Employee
during the term of his employment, consulting, or similar relationship with the
Company which relates directly or indirectly to the Company's current or planned
lines of business and is made through the use of any of the Confidential
Information of the Company or any of the Company's equipment, facilities, trade
secrets or time, or which results from any work performed by Employee for the
Company, shall belong exclusively to the Company and shall be deemed a part of
the Confidential Information for purposes of this Agreement. Employee hereby
assigns and agrees to assign to the Company all rights in and to such
Confidential Information whether for purposes of obtaining patent or copyright
protection or otherwise. Employee shall acknowledge and deliver to the Company,
without charge to the Company (but at its expense) such written instruments and
do such other acts, including giving testimony in support of Employee's
authorship or inventorship, as the case may be, necessary in the opinion of the
Company to obtain patents or copyrights or to otherwise protect or vest in the
Company the entire right and title in and to the Confidential Information.

     8. LOYALTY DURING EMPLOYMENT TERM. Employee agrees that during the term of
Employee's employment by the Company, Employee will devote substantially all of
Employee's business time and effort to and give undivided loyalty to the
Company, and will not engage in any way whatsoever, directly or indirectly, in
any business that is competitive with the Company or its affiliates, nor
solicit, or in any other manner work for or assist any business which is
competitive with the Company or its affiliates. During the term of Employee's
employment by the Company, Employee will undertake no planning for or
organization of any business activity competitive with the Company or its
affiliates, and Employee will not combine or conspire with any other employee of
the Company or any other person for the purpose of organizing any such
competitive business activity.

     9. NON-COMPETITION; NON-SOLICITATION. The parties acknowledge that Employee
will acquire much knowledge and information concerning the business of the
Company and its affiliates as the result of Employee's employment. The parties
further acknowledge that the scope of business in which the Company is engaged
as of the date of execution of this Agreement is world-wide and very competitive
and one in which few companies can successfully compete. Certain activities by
Employee after this Agreement is terminated would severely injure the Company.
Accordingly, until one year after this Agreement is terminated or Employee
leaves the employment of the Company for any reason, Employee will not:

          a. Engage in any work activity for or in conjunction with any business
or entity that is in competition with or is preparing to compete with the
Company;

          b. Persuade or attempt to persuade any potential customer or client to
which the Company or any of its affiliates has made a proposal or sale, or with
which the Company or any of its affiliates has been having discussions, not to
transact business with the Company or such affiliate, or instead to transact
business with another person or organization;

                                       4
<PAGE>
          c. Solicit the business of any customers, financing sources, clients,
suppliers, or business patrons of the Company or any of its predecessors or
affiliates which were customers, financing sources, clients, suppliers, or
business patrons of the Company at any time during Employee's employment by the
Company, or within three years prior to the Effective Date of Employee's
employment, provided, however, that if Employee becomes employed by or
represents a business that exclusively sells products that do not compete with
products then marketed or intended to be marketed by the Company, such contact
shall be permissible; or

          d. Solicit, endeavor to entice away from the Company or any of its
affiliates, or otherwise interfere with the relationship of the Company or any
of its affiliates with, any person who is employed by or otherwise engaged to
perform services for the Company or any of its affiliates, whether for
Employee's account or for the account of any other person or organization.

     10. INJUNCTIVE RELIEF. It is agreed that the restrictions contained in
Sections 8, 9 and 10 of this Agreement are reasonable, but it is recognized that
damages in the event of the breach of any of those restrictions will be
difficult or impossible to ascertain; and, therefore, Employee agrees that, in
addition to and without limiting any other right or remedy the Company may have,
the Company shall have the right to an injunction against Employee issued by a
court of competent jurisdiction enjoining any such breach without showing or
proving any actual damage to the Company. This paragraph shall survive the
termination of Employee's employment.

     11. PART OF CONSIDERATION. Employee also agrees, acknowledges, covenants,
represents and warrants that he is fully and completely aware that, and further
understands that, the restrictive covenants contained in Sections 8, 9, and 10
of this Agreement are an essential part of the consideration for the Company
entering into this Agreement and that the Company is entering into this
Agreement in full reliance on these acknowledgments, covenants, representations
and warranties.

     12. TIME AND TERRITORY REDUCTION. If any of the periods of time and/or
territories described in Sections 8, 9 and 10 of this Agreement are held to be
in any respect an unreasonable restriction, it is agreed that the court so
holding may reduce the territory to which the restriction pertains or the period
of time in which it operates or may reduce both such territory and such period,
to the minimum extent necessary to render such provision enforceable.

     13. SURVIVAL. The obligations described in Sections 8 and 10 of this
Agreement shall survive any termination of this Agreement or any termination of
the employment relationship created hereunder.

     14. NONDELEGABILITY OF EMPLOYEE'S RIGHTS AND COMPANY ASSIGNMENT RIGHTS. The
obligations, rights and benefits of Employee hereunder are personal and may not

                                       5
<PAGE>
be delegated, assigned or transferred in any manner whatsoever, nor are such
obligations, rights or benefits subject to involuntary alienation, assignment or
transfer. Upon mutual agreement of the parties, the Company upon reasonable
notice to Employee may transfer Employee to an affiliate of the Company, which
affiliate shall assume the obligations of the Company under this Agreement. This
Agreement shall be assigned automatically to any entity merging with or
acquiring the Company.

     15. AMENDMENT. Except for documents regarding the grant of stock options
and an Invention, Confidential Information and Non-Competition Agreement, this
Agreement contains, and its terms constitute, the entire agreement of the
parties and supersedes any prior agreements, including any Employment
Agreements, and it may be amended only by a written document signed by both
parties to this Agreement.

     16. GOVERNING LAW. This Agreement shall be governed by and construed and
enforced in accordance with the internal laws of the State of Arizona, exclusive
of the conflict of law provisions thereof, and the parties agree that any
litigation pertaining to this Agreement shall be in courts located in Maricopa
County, Arizona.

     17. ATTORNEYS' FEES. If any party finds it necessary to employ legal
counsel or to bring an action at law or other proceeding against the other party
to enforce any of the terms hereof, the party prevailing in any such action or
other proceeding shall be paid by the other party its reasonable attorneys' fees
as well as court costs all as determined by the court and not a jury.

     18. NOTICES. All notices, demands, instructions, or requests relating to
this Agreement shall be in writing and, except as otherwise provided herein,
shall be deemed to have been given for all purposes (i) upon personal delivery,
(ii) one day after being sent, when sent by professional overnight courier
service from and to locations within the Continental United States, (iii) five
days after posting when sent by United States registered or certified mail, with

Agreement or at any other address such person or entity has designated by
