AMENDED AND RESTATED
                                 PROMISSORY NOTE
                                    (Secured)

$1,000,000 U.S.                                                    June 27, 2000

     This Amended and Restated Promissory Note ("Note") I entered into effective
June 27,  2000 and is  intended  to amend,  restate  and  replace  that  certain
Promissory  Note  executed  by Maker and  dated  June 27,  2000 in the  original
principal amount of $860,000,  and reflect the fact that the original  principal
amount owed by Maker as of June 27, 2000 is actually $1,000,000.

     This  Amended  and  Restated  Promissory  Note is secured  by that  certain
Security  Agreement  between  Maker and Holder  dated June 27,  2000 and amended
effective as of June 27, 2000 to reflect the actual original  indebtedness under
the Note to be $1,000,000.

     Now  therefor:  For value  received,  Klever  Marketing,  Inc.  a  Delaware
corporation ("Maker*),  promises to pay to Presidio Investments, LLC, an Arizona
limited partnership ("Holder"),  or order, at 1850 N. Central Avenue, Suite 500,
Phoenix, Arizona 85004, Attention:  William J. Howard, Esq., or such other place
as the holder may from time to time  designate in writing,  the principal sum of
One Million Dollars  ($1,000,000 U.S.) (the "Loan Amount"),  advanced under this
promissory  note ("Note") with interest from the date first written above on the
unpaid principal balance at the rate of eight percent (8.0%) per annum.

     The Loan  Amount  under  this Note  shall be due and  payable  as  follows:
Interest is to be paid  quarterly  with the first  payment due on September  30,
2000. Principal and all due and unpaid interest and other amounts due under this
Note are to be paid on May 1,2001.

     This  Note  may be  prepaid  in whole or in part at the  option  of  Maker,
without penalty, provided,  however, that such prepayment shall be first applied
to interest accrued to the date of prepayment and then to principal.

     Maker  acknowledges  that late payment to Holder will cause Holder to incur
costs not  contemplated  by this  Note,  the exact  amount of such  costs  being
difficult and impracticable to assess.  Such costs include,  without limitation,
processing  and  accounting  charges.  Therefore,  in the event any  payment  or
portion  thereof  due upon this Note is not paid  within five (5) days after its
due date,  the  Maker  agrees  to pay the  holder  hereof,  in  addition  to the
delinquent  installment and any accrued Interest thereon, a late charge equal to
five percent (5%) of the  delinquent  amount.  The parties  agree that this late
charge  represents a fair and  reasonable  estimate of the costs that the holder
hereof will incur by reason dr such late payment.

     Each payment  tendered  hereunder  shall be credited first on interest then
due; the  remainder on  principal;  and the  interest  thereon  shall cease upon
principal so credited.  Should default be made on payment of any  installment of
principal or interest,  the whole sum of principal  and interest  shall,  at the
option of the holder of this Note become immediately due. Principal and interest
shall be payable in lawful money of the United States.

     The occurrence of any of the following  events shall constitute an event of
default hereunder, and If not cured within ten (10) days, shall entitled Holder,
at his  option,  without  notice  or  demand  to Maker  to  declare  the  entire
indebtedness due and payable at once and in full:

     1. Any default in the payment of any  installment  of principal or interest
        due on this Note as herein above provide

     2. Any  failure  by Maker to  perform  each and every  material  condition,
        covenant and  agreement to be  performed  by it in  accordance  with the
        terms  of this  Note,  or the  failure  by it to  perform  any  material
        condition,  covenant, or agreement now or hereinafter agreed by it to be
        performed in connection with the payment of the  indebtedness  evidenced
        by this  Note,  or in any  agreement  securing  or  collateralizing  the
        payment of the indebtedness evidenced by this Note.

     3. Any event of  insolvency  of.  general  assignment  for the  benefit  of
        creditors by, judgment against, the appointment of a receiver or trustee
        with respect to or petition of bankruptcy by or against any party liable
        hereunder orunder any agreement securing or collateralizing  the payment
        of the indebtedness evidenced by this Note.

     4. Default  In the  payment  of any other  indebtedness  due  Holder or the
        default in the performance of any other  obligation to the holder hereof
        by the Maker or any other party liable for the payment  hereof,  whether
        as endorser, guarantor, surety or otherwise.

     Failure of Holder of this Note to declare such indebtedness to be due shall
not constitute a waiver of the right to later declare the entire indebtedness to
be at once due and payable.

     Maker hereby waives as to this debt, or any renewal thereof,  all rights of
exemption under the laws of Arizona as to personal property it agrees to pay all
costs of  collection  or securing or  attempting to collect or secure this Note,
including  reasonable  attorneys' fees, whether the same be collected or secured
by any attorney  consulted  with  reference to a lawsuit or otherwise.  Maker of
this Note waives protest,  notice of protest,  suit and all other.  requirements
necessary to hold it liable hereunder, and it agrees that time of payment may be
extended  or a renewal  note taken or the  security  substituted  or released in
whole or in part or other  indulgence  granted without notice of, or consent to,
such action, without release of liability of any such party.

     As  security  for the  repayment  of this Note the Makers  have  executed a
Security Agreement of even date.

     Maker has caused this Note to be executed,  and is effective as of the date
first above written in Maricopa County, Arizona.
