Clark County, Nevada



         1. FOR VALUE RECEIVED, CONCORDIA LAND, LLC, a Nevada Limited Liability
Company, ("BORROWER"), promises to pay to the order of ASI Technology
Corporation., a Nevada Corporation, (the "Lender"), at 980 American Pacific
Drive, Suite #111, Henderson, NV 89014, or at such other place as Lender from
time to time may designate, the principal sum of Nine Hundred Eighty Five
Thousand ($985,000.00) Dollars, which is the outstanding balance of Promissory
Note dated October 12, 2005 in the amount of $985,000.00.

         2. The principal sum outstanding from time to time shall bear simple
interest at the rate of fifteen percent (15%) per annum. Unless paid to obtain
partial reconveyance of the lien of the Guaranty, interest shall not otherwise
be payable until the Maturity Date (as defined below), and will accrue as simple
interest and not be compounded until that time. Interest shall be calculated on
the basis of a 365-day year and actual days elapsed.

         3. All principal and accrued and unpaid interest shall be due and
payable no later than six (6) months after the date of this Note (the "Maturity
Date"). Lender shall receive 0% of the loan amount as the loan origination fee,
paid upon the Maturity Date.

         4. Borrower may prepay some or all of the principal under this Note,
without penalty or premium.

         5. If any of the following "EVENTS OF DEFAULT" occur, any obligation of
the holder to make advances under this Note shall terminate, and at the holder's
option, exercisable in its sole discretion, all sums of principal and interest
under this Note shall become immediately due and payable without notice of
default, presentment or demand for payment, protest or notice of nonpayment or
dishonor, or other notices or demands of any kind or character:

                  (a)      Borrower fails to perform any obligation under this
                           Note to pay principal or interest when due; or

                  (b)      Borrower fails to perform any other obligation under
                           this Note to pay money when due; or

                  (c)      An event of default occurs, except as provided in
                           SECTION7 BELOW.

         6. It shall be an "EVENT OF DEFAULT" under this Note if Borrower
becomes the subject of any bankruptcy or other voluntary or involuntary
proceeding, in or out of court, for the adjustment of debtor-creditor
relationships ("Insolvency Proceeding"). If that happens, all sums of principal
and interest under this Note shall automatically become immediately due and
payable without notice of default, presentment or demand for payment, protest or
notice of nonpayment or dishonor, or other notices or demands of any kind or
character.

         7. All amounts payable under this Note are payable in lawful money of
the United States during normal business hours on a Business Day, as defined
below.

         8. If any lawsuit or arbitration is commenced which arises out of or
relates to this Note or the Guaranty, the prevailing party shall be entitled to
recover from each other party such sums as the court or arbitrator may adjudge
to be reasonable attorneys' fees in the action or arbitration, in addition to
costs and expenses otherwise allowed by law. In all other situations, including
any matter arising out of or relating to any Insolvency Proceeding, Borrower
agrees to pay all of Lender's cost and expenses, including attorneys' fees,
which may be incurred in enforcing or protecting Lender's rights or interests.

         9. This Note is governed by the laws of the State of Nevada, without
regard to the choice of law rules of that State.

         10. Borrower agrees that the holder of this Note may accept additional
or substitute security for this Note, or release any security or any party
liable for this Note, or extend or renew this Note, all without notice to
Borrower and without affecting the liability of Borrower.

         11. If Lender delays in exercising or fails to exercise any of its
rights under this Note, that delay or failure shall not constitute a waiver of
any of Lender's rights, or of any breach, default or failure of condition of or
under this note. No waiver by Lender of any of its rights, of any such breach,
default or failure of conditions shall be effective, unless the waiver is
expressly stated in a writing signed by Lender. All of Lender's remedies in
connection with this Note or under applicable law shall be cumulative, and
Lender's remedies in connection with this Note or under applicable law shall be
cumulative, and Lender's exercise of any one or more of those remedies shall not
constitute an election of remedies.

         12. This Note insures to and binds the heirs, legal representatives,
successors and assigns of Borrower and Lender; provided, however, that Borrower
may not assign this Note or any loan funds, or assign or delegate any of its
rights or obligations, without the prior written consent of Lender in each
instance.
