(f)  Effect of Termination Pursuant to Section 2.1(a). Upon termination
     ------------------------------------------------- of employment in
     accordance with Section 2.1(a), in lieu of any benefits under Section 1.4
     other than Section 1.4(a) and any benefits required to be provided to
     Employee by law, and contingent (i) on the Employee's execution, delivery,
     and non-revocation of a general release in favor of the Company, its
     subsidiaries, affiliates, and each of their officers, directors, employees
     and agents, in which Employee executes a release of all known, unknown,
     past, future and other claims against the Company, other than claims for
     the breach of this Agreement, which release (the "Release Agreement") shall
     be in form and substance satisfactory to the Company in its sole and
     absolute discretion, and (ii) the Employee's compliance with all other
     provisions hereof, the Employee will be entitled to the following benefits:

     Date of Termination until March 31, 2010, monthly payments of $25,000.00
     payable on the last day of each month (pro-rated for any partial month),
     and on the later of the Date of Termination and April 30, 2010, a lump sum
     payment of $525,000.00 (less any salary payments made with respect to the

     long as such period does not extend beyond the 10th anniversary of the

     Company shall not be liable or obligated in any way to Employee for tax
     or other effects of such modifications);

                     12/31/01     12/31/11

                     12/31/02     12/31/11 to 06/30/12
                       7/1/03     12/31/11 to 06/30/12

                     12/31/02     12/31/11 to 06/30/12
                       7/1/04     12/31/11 to 06/30/12
                     12/31/04     12/31/11 to 06/30/12
                     12/31/04     12/31/11 to 06/30/12
                     12/31/05     12/31/11 to 06/30/12
                      1/1/07      12/31/11 to 06/30/12

     The Company hereby agrees to the cashless exercise of Employee's options
     provided for in this section and to take such steps necessary to effectuate
     such exercise.

     (iii) subject to the last paragraph of this Section 2.1(f) hereof, one
     million (1,000,000) shares of the Company's common stock, which shall be
     granted subject to Employee's making provision reasonably acceptable to
     the Company to pay all withholding taxes with respect to such shares;

     (iv) the immediate grant of all right, title and interest (without any
     encumbrances or restrictions) in Employee's office furniture at the time of
     his termination, which grant shall not include any of the Company's
     artwork;

     and

     (v) the Company shall transfer, and Employee shall immediately take all
     actions reasonably requested by the Company to accept, title to the
     Company-owned vehicle in Employee's possession. The fair market value of
     the vehicle (as determined by reference to the Kelly Blue Book guide,
     using trade-in value in "good" condition as of the Date of Termination)
     shall be deducted from the lump sum payment made to Employee pursuant to
     Section 2.2(f)(i);


Notwithstanding the foregoing, the delivery of 1,000,000 shares of common stock
and payment of cash amounts payable to the Employee pursuant to this Agreement
from his separation from service to the Delayed Payment Date will be made on the
Delayed Payment Date.  The term "Delayed Payment Date" shall mean the date that
is six (6) months and one (1) day after the Date of Termination.

<PAGE>

Additionally, Employee and the Company have reached a preliminary and
non-binding understanding with respect to the material terms of an asset sale
whereby Employee would purchase from the Company all right, title and interest
(without any encumbrances or restrictions) in (a) the "Mobile MaxPure" name and
line of business (including all associated equipment, hard assets and software),
(b) the "WorldWater & Solar Technologies" name and (c) the intellectual property
associated with Mobile MaxPure (collectively, the "Assets").  Employee would not
assume any existing warranty obligations or any liabilities for sales or
activities prior to the date of closing on a definitive asset purchase
agreement.  The total purchase price of the Assets would be $250,000 (the
"Purchase Price").  In the event Employee and the Company enter into a mutually
acceptable asset purchase agreement,  $225,000 of the Purchase Price will be
considered to have been paid prior to closing as a result of Employee's
agreement, as set forth in this Amendment, to a reduction in the severance
benefits that would have otherwise been potentially due to Employee under the
terms of the Employment Agreement. If, for any reason, the sale and purchase of
the Assets does not occur, Employee shall not be entitled to any increase or
change in the severance benefits as set forth in this Amendment.  The remaining
$25,000 of the Purchase Price would be paid in cash in the form of a $25,000
deduction from the lump sum payment of $525,000 referenced in Section 2.2(f)(i)
hereof.  The provisions of this paragraph are intended solely as a basis for
further discussion and are not intended to be and do not constitute a legally
binding offer or obligation and are subject in all respects to the negotiation,
execution, and delivery of mutually acceptable definitive documentation by and
among the parties with respect to the sale and purchase of the Assets.

                                  Section 7

     Section 2 shall be amended by adding a new subsection 2.2(g) to read as
     follows:

     (g)     Resignations.      Effective immediately upon the Date of
             ------------       Termination, Employee hereby resigns from the
             Board of Directors of the Company and each of its subsidiaries,
             and from all other positions with such entities, and agrees to
             promptly deliver notices of resignation and to take such further
             actions as are requested by the Company to effect such resignation,
             immediately upon the Company's request.


                                  Section 8

     The Employment Agreement shall be amended by adding a new Section 3.5 to
read as follows:

3.5     No Restrictive Covenants.  The Employee is not subject to any
        ------------------------
restrictive covenants other than as expressly set forth in this Article III.

<PAGE>
                                  Section 9

          Section 4.1 is hereby deleted.


                                  Section 10

     The Employment Agreement shall be amended by adding a new Section 4.10 to
read as follows:

4.10     Compliance with Code Section 409A.  The parties intend that this
         ---------------------------------
Employment Agreement meet the requirements of Section 409A of the Code (and any
successor provisions of the Code) and the regulations and other guidance issued
thereunder (the "Requirements") and be operated in accordance with such
Requirements so that benefits under this Plan shall not be included in income
under Section 409A of the Code.  Any ambiguities in this Plan shall be construed
to effect the intent as described in this Section 4.10.  If any provision of
this Plan is found to be in violation of the Requirements, then such provision
shall be deemed to be modified or restricted to the extent and in the manner
necessary to render such provision in conformity with the Requirements, or shall
be deemed excised from this Plan, and this Plan shall be construed and enforced
to the maximum extent permitted by the Requirements as if such provision had
been originally incorporated in this Plan as so modified or restricted, or as if
such provision had not been originally incorporated in this Plan, as the case
may be, provided that notwithstanding any other provision hereof to the
contrary, no such severance, excise or construction that would materially
increase the Company's obligations or reduce the Company's benefits under this
Agreement shall be effected without the Company's consent, which may be withheld
in its sole and absolute discretion.  The Company makes no representation or
warranty to Employee regarding the Compliance with this Agreement with the
Requirements, and shall have no obligation to Employee with respect thereto.

For the period beginning on January 1, 2007 and ending on December 31, 2008, the
Employment Agreement has been administered in good faith compliance with the
requirements of Section 409A of the Code in accordance with the applicable
guidance from the Internal Revenue Service.


                                   Section 11

    Employee represents and warrants to the Company that Employee has no
knowledge of any breach by the Company of any of its obligations under the
Agreement as of the date hereof, and, except for such benefits as cannot be
waived by law, voluntarily waives his right to assert any such claims, known or
unknown, accrued or contingent, in exchange for the benefits set forth herein.
Except as amended by this First Amendment, the Employment Agreement shall remain
in full force and effect.
