                           CONVERTIBLE PROMISSORY NOTE

Principal:  $262,500.00                                    Date: January 1, 2008

For value  received,  the  undersigned  NexHorizon  Communications,  Inc. or its
successor   ("NexHorizon")   ("the   Promisor")  at  9737   Wadsworth   Parkway,
Westminster,  CO 80021 promises to pay to the order of Barbara  Altbaum  trustee
and ULTRONICS,  ("Payee"), at 396 "E" Street, Chula Vista, CA 91910, (or at such
other place as the Payee may designate in writing) the sum of  $262,500.00  plus
accrued interest of 6% annually; interest shall be paid quarterly with the final
interest and principal balance due and payable in full on December 31, 2010.

The unpaid  principal and accrued interest will be due (the "Due Date") in three
(3) years from the date of this agreement or an earlier date with no penalty for
earlier repayment.

Commencing 12 months after date hereof,  this three year Convertible  Promissory
Note, at the Payee's option,  may be paid in full by accepting the principal and
all accrued interest in exchange for restricted  common stock of Holder Maker at
conversion  rate of the average  previous  five (5) business  day closing  "Ask"
price. As an example,  if the principal and accrued  interest to date is $10,000
then this  would be paid off in full  with the  issuance  of  50,000  restricted
common shares (if the 5 day closing Ask price is $0.20 per share, then $10,000 /
$0.20 = 50,000).

If the  Convertible  Promissory  Note is  paid  off in  full  by  accepting  the
restricted  common stock the Payee is hereby  granted  "Piggy-Back  Registration
Rights."

Should the Convertible  Promissory Note not be paid off in full,  either in cash
on the Due Date or commencing 12 months after date hereof, the accruing interest
rate will be changed to the rate of 10% annually.

All payments on this note shall be applied first in payment of accrued  interest
and any remainder in payment of principal.

All payments of principal and interest on this Convertible Promissory Note shall
be paid in the legal currency of the United States.  Promisor waives presentment
for payment, protest, and notice of protest and nonpayment of the Note.

If any one or more of the  provisions of this  Convertible  Promissory  Note are
determined  to be  unenforceable,  in  whole  or in part,  for any  reason,  the
remaining provisions shall remain fully operative.

In the event of any proceedings  regarding the interpretation and/or enforcement
of this  Promissory  Note,  the  prevailing  party  shall be entitled to recover
reasonable attorneys' fees and costs of suit.

                                                                               1
