Exhibit 10.43

                           May 8, 2007 PROMISSORY NOTE

US $1,250,000.00                                                    May 8, 2007

         FOR VALUE RECEIVED, Fittipaldi Logistics, Inc., a Nevada corporation
(the "Maker"), promises to pay to the order of The Black Diamond Fund, LLLP (the
"Holder"), a Minnesota Limited Partnershp having a place of business at 3346
Commercial Avenue, Northbrook, Illinois 60062, or such address as the Holder may
from time to time designate in writing to the Maker, the principal sum of One
Million Two Hundred Fifty Thousand Dollars ($1,250,000) with interest on the
unpaid balance as hereinafter provided.

         Interest on this Note at the rate of 16.0% per annum, compounded daily,
shall accrue and be payable on the Maturity Date as hereinafter defined.

         The principal amount of this Note and all accrued but unpaid interest
shall be due and payable on the nine-month anniversary of the date of issuance
of the Note (the "Maturity Date"). Notwithstanding the foregoing, the Maker may
prepay up to all the principal amount of this Note and all accrued but unpaid
interest at any time without incurring any penalty.

         The following shall constitute "Events of Default" under this Note:

         1.       The Maker fails to make the payment required by this Note
                  within 15 days of its due date.

         2.       The Maker becomes insolvent or unable to pay its debts as they
                  mature or makes an assignment for the benefit of creditors, or
                  any proceeding is instituted by or against the Maker alleging
                  that the Maker is insolvent or unable to pay its debts as they
                  mature, and any such proceeding, if involuntary, is not
                  dismissed or stayed on appeal or otherwise within 30 days.

         Upon the occurrence of an Event of Default, the entire unpaid principal
amount of this Note together with accrued but unpaid interest thereon, shall at
once become due and payable without requiring notice by the Holder. Failure to
provide notice shall not constitute a waiver of this right. From the date of the
Event of Default, interest shall accrue at a rate of the lesser of 32% per annum
or the maximum rate permitted by applicable law, compounded daily. Additionally,
there shall be a monthly Default Administrative Fee equal to 5,000 shares of the
Maker's Series I preferred stock ("Preferred Stock") held by the Escrow Agent
due on the date of the Event of Default and every 30 days thereafter until full
repayment of all amounts due under this Note.

         Upon the final settlement of all of Maker's obligations to the Holder
of the Maker's Series B 5% secured convertible debentures, this Note shall
become secured by the same collateral as was used to secure the Series B 5%
secured convertible debentures with the exception of the assets related to the
Maker's trucking operations that are held by Fittipaldi Carriers, Inc., a
Florida corporation, and its subsidiaries.

         It is the intent of the parties that in no event shall the amount of
interest due or payment in the nature of interest payable hereunder exceed the
maximum rate of interest permitted by applicable law, as may be in effect from
time-to-time, and in the event the amount of interest due or payable hereunder
exceeds such maximum rate, interest shall be reduced to the maximum amount that
is permitted by applicable law and the payment of any such excess shall be
deemed to be a prepayment of principal.

<PAGE>
         This Note shall be governed and construed in accordance with the laws
of the State of Illinois, without regard to conflict of laws principles thereof.
The Maker hereby consents to the jurisdiction of the courts located in Cook
County, Illinois, as the exclusive forum to resolve any disputes arising out of
this Note. The Maker hereby waives any objection it may have to the jurisdiction
of such courts or the laying of venue in such county.

         The Maker agrees to pay or reimburse the Holder and any other holder
hereof of all costs and expenses of preparing, seeking advice in regard to,
enforcing, and preserving its rights under this Note or any guarantee, document
or instrument executed in the connection herewith (including reasonable
attorneys' fees and costs and reasonable time charges of attorneys who may be
employees of the Holder, whether in or out of court, in original or appellate
proceedings or in bankruptcy.)

         Except as provided in this Note, presentment, protest, notice, notice
of dishonor, demand for payment, notice of protest and notice of non-payment are
hereby waived.

         The failure or delay by the Holder of this Note in exercising any of
his rights hereunder in any instance shall not constitute a waiver thereof in
that or any other instance. The Holder of this Note may not waive any of its
rights, except in an instrument in writing signed by the Holder.

         This Note may not be amended except in a writing signed by the Maker.
