FOR
      VALUE
      RECEIVED, ITREX INTERNATIONAL CORPORATION, a Delaware corporation (“Itrex” or
      the “Borrower”), a wholly-owned subsidiary of Orbit Brands Corporation (“Orbit”
or the “Company”), hereby promises to pay to M2B, Inc. (“Holder”), the sum of
      Twenty-Five Thousand Dollars ($25,000.00) on the second anniversary date
      following the confirmation of the Company’s Chapter 11 Plan of Reorganization
      (the “Maturity Date”), together with accrued interest thereon. The Maturity Date
      is estimated to occur by December 31, 2008. Borrower shall repay the principal
      and any accrued but unpaid interest due under this Promissory Note (the “Note”)
      on the Maturity Date, by check or wire transfer to the party who is the
      registered holder of this Note (“Holder’s Agent”). Whenever any payment to be
      made hereunder falls due on a Saturday, Sunday or business holiday in Los
      Angeles, California, such payment may be made on the next succeeding business
      day, and such extension of time will, in such case, be included in computing
      interest, if any, in connection with such payment.





Interest
      shall accrue on the principal amount of this Convertible Promissory Note (the
      “Note”) at a fixed simple rate of five percent (5%) per annum, calculated on the
      actual number of days elapsed, on the basis of a 360-day year. Interest shall
      be
      payable in kind (convertible into shares of the Company’s common stock) or cash.
      The principal and all accrued interest may be converted into fully paid and
      nonassessable shares of common stock of the Company at the conversion price
      (defined hereinbelow) at the option of the Company, in the event that the
      principal and all accrued interest are not paid in full in cash on the Maturity
      Date.





The
      conversion price shall be $0.002 per share (the “Conversion Price”). Any
      fractional shares issuable upon conversion of this Note shall be rounded down
      to
      the nearest whole share. The Company intends that all such shares issuable
      upon
      conversion of the Note shall be registered pursuant to Section 1145 of the
      Bankruptcy Code (Title 11, United States Code, Section 1145).





The
      Conversion Price and the number of shares issuable upon conversion shall be
      proportionally adjusted upon the occurrence of an “Adjustment Event,” defined as
      any reclassification of the Company’s common stock, recapitalization, merger or
      consolidation, or like capital adjustment affecting the number of outstanding
      shares of common stock of the Company. The good faith determination by the
      Company’s Board of Directors as to what adjustments, amendments or arrangements
      shall be made to the Conversion Price, and the extent thereof, shall be final
      and conclusive, provided that the Conversion Price is adjusted in a manner
      that
      is no less favorable than the manner of adjustment used as to any other person
      with similar adjustment rights.





Conversion
      of all or a part of this Note shall be effectuated by submitting a written
      notice (the “Notice of Conversion”) in the form of Notice of Conversion attached
      hereto as Exhibit “1” and incorporated herein by reference, executed by the
      Company, evidencing the Company’s intention to convert this Note or a specified
      portion thereof. No fraction of a share will be issued on conversion, but the
      number of shares issuable shall be rounded down to the nearest whole share.
      The
      date on which Notice of Conversion is given (the “Conversion Date”) shall be
      deemed to be the date on which the Holder or Holder’s Agent first receives the
      Notice of Conversion. Certificates representing Common Stock upon conversion
      will be delivered to the Holder or Holder’s Agent within ten (10) trading days,
      subject to reasonable delay for processing by the Company’s transfer agent, if
      any, from the date the Notice of Conversion is delivered to the Holder or
      Holder’s Agent (“Delivery Date”). Delivery of shares upon conversion shall be
      made to the address specified by the Holder or the Holder’s Agent in the
      Company’s Notice of Conversion.

Any
      notice herein required or permitted to be given shall be presented in writing
      and sent by means of certified or registered mail, express mail, or other
      overnight delivery service, hand-delivery confirmed by signed receipt, or
      facsimile transmission (followed by prompt transmission of the original of
      such
      notice by any of the foregoing means or by regular U.S. Mail), in each case
      with
      proper postage or other charges prepaid and addressed or directed to the Holder
      or to the Holder’s Agent at their respective addresses. Such notice(s) shall be
      deemed given when actually issued. Any party may change its address and
      facsimile number for receipt of notices by service of notice to the other party
      as herein provided.





The
      following events shall constitute an “Event of Default” hereunder:





(a)
            If
                the Company fails to issue shares of common stock to the Holder or
                the
                Holder’s Agent, which shares can be immediately resold in the public
                securities market, or if it fails to cause its Transfer Agent to
                issue
                shares of common stock upon the proper exercise by the Company of
                its
                conversion rights in accordance with the terms of this Note;
                or





(b)
            If
                Borrower shall, without cause, fail to perform or observe, in any
                material
                respect, any other material covenant, term, provision, condition,
                agreement or obligation of Borrower under this Note, and such failure
                shall continue uncured for a period of thirty (30) days after written
                notice thereof shall have been provided to Borrower with respect
                to such
                failure.





Borrower
      hereby waives demand for payment, notice of nonpayment, presentment, notice
      of
      dishonor, protest, and notice of protest. If default shall occur in the payment
      of this Note, Borrower shall pay the Holder or Holder’s Agent hereof its costs
      of collection, including but not limited to its reasonable attorneys’ fees.





This
      Note
      shall be governed by the internal laws of the State of California.





This
      Note
      constitutes the entire agreement between the parties, and none of the parties
      is
      relying on any prior or contemporaneous oral representation or promise, or
      any
      omission of any information, in entering into this Note.





IN
      WITNESS WHEREOF, Borrower has caused this Note to be signed in its name, by
      its
      duly authorized representative, on or as of the date first written above.
