            Laurus Master Fund, Ltd. also entered into a stock redemption
      agreement, dated as of January 12, 2006, as amended on February 28, 2006
      (the "Redemption Agreement"), pursuant to which the Company agreed to
      purchase the Existing Shares and the Note Shares for a purchase price per
      share to be determined pursuant to a formula set forth in the Redemption
      Agreement, which purchase price shall not be less than $.20 per share or
      more than $.34 per share. Such purchase is subject to customary closing
      conditions, including, among other things, the consummation of the Asset

      subject to a number of limited exceptions, to not (i) directly or
      indirectly, sell, assign, transfer, encumber, pledge or otherwise dispose
      of, or enter into any contract, option or other agreement, arrangement or

      transfer, encumbrance, pledge or other disposition of, any of its shares
      of Company common stock and (ii) seek or solicit any sale, assignment
      transfer, encumbrance, pledge or other disposition of its shares of

      to the cancellation, as of the closing date of the Asset Sale, of the then
      unexercised portion of the following warrants that it holds: (i) the
      warrant, dated November 25, 2003, to purchase up to 4,250,000 shares of
      common stock of the Company at an exercise price of $0.30 per share, which
      warrant expires on November 24, 2010 and (ii) the warrant, dated November
      26, 2004, to purchase up to 500,000 shares of common stock of the Company
      at an exercise price of $0.30 per share, which warrant expires on November
      26, 2011 (collectively, the "Warrants"). Laurus Master Fund, Ltd. further
      agreed not to exercise the Warrants before the earlier of (x) May 31, 2006
      and (y) the date on which the Purchase Agreement is terminated. In
      addition, on or after May 31, 2006, the agreements could have been
      terminated by either party if the Asset Sale had not occurred.

            On June 9, 2006, Laurus Master Fund, Ltd. and the Company entered
      into a second amendment to the Redemption Agreement (the "Redemption
      Agreement Amendment"), which is effective as of April 21, 2006, pursuant
      to which Laurus Master Fund, Ltd. agreed to change the date before which
      it would not exercise the Warrants from May 31, 2006 to September 30,
      2006. In addition, on September 30, 2006, the agreements can be terminated
      by either party if the Asset Sale has not occurred.

            Concurrently, with the execution of the Voting Agreement, the
      Redemption Agreement and the Conversion Agreement, Laurus Master Fund,
      Ltd. also entered into (i) a letter agreement, dated as of January 12,
      2006 (the "Cash Collateral Deposit Letter"), with the Company and its
      subsidiaries, Tidel Engineering, L.P., Tidel Cash Systems, Inc., Tidel
      Services, Inc. and AnyCard International, Inc., and (ii) a reaffirmation,
      ratification and confirmation agreement, dated as of January 12, 2006 (the
      "Reaffirmation Agreement"), with the Company. Pursuant to the Cash
      Collateral Deposit Letter, the parties thereto agreed that a portion of
      the $8,200,000 of proceeds (the "Deposit Amount") from the January 2006


                                      -9-


      sale of the Company's automated teller machine business that were on
      deposit with Laurus Master Fund, Ltd. for repayment of outstanding Company
      indebtedness to Laurus Master Fund, Ltd. would be applied to repay all
      amounts owing to Laurus Master Fund, Ltd. under (i) the portion of the
      2003 Note remaining after the Conversion, (ii) a convertible term note,
      dated November 26, 2004 in the aggregate principal amount of $600,000,
      which was convertible into shares of common stock of the Company at a
      conversion price of $0.30 per share and (iii) a convertible term note,

      which was convertible into shares of common stock of the Company at a
      conversion price of $3.00 per share (collectively, the "Notes").
      Thereafter, the Notes shall be deemed to have been indefeasibly repaid and
      the Deposit Amount will be reduced to $5,330,507. Under the Cash
      Collateral Deposit Letter, such remaining Deposit Amount together with an
      additional cash deposit of $69,493 from the Company will be used as
      collateral to secure the Company's obligations to Laurus Master Fund, Ltd.
      under, among other things, the Redemption Agreement and the Conversion
      Agreement. Pursuant to the Reaffirmation Agreement, the Company, among
      other things, acknowledged and reaffirmed its obligation to pay to Laurus
      Master Fund, Ltd. simultaneously with the closing of the Asset Sale the
      amounts payable to Laurus Master Fund, Ltd. pursuant to Section 4 of the
      Agreement Regarding NCR Transaction and Other Asset Sales (the "NCR
      Agreement), dated as of November 26, 2004, between the Company and Laurus
      Master Fund, Ltd., which amount will be determined in accordance with the
      provisions of such section and shall not be less than $5,000,000 nor more
      than $11,000,000.

            On June 9, 2006, the Company, Tidel Engineering, L.P. and Laurus
      Master Fund, Ltd. entered into an agreement (the "Termination Agreement")
      pursuant to which the Company shall pay to Laurus Master Fund, Ltd., upon
      the consummation of the Asset Sale, an amount equal to $8,508,963 (the
      "Sale Fee"), in satisfaction of the Company's obligations to Laurus Master
      Fund, Ltd. under the NCR Agreement. Upon payment of the Sale Fee the
      parties' obligations under the Reaffirmation Agreement shall terminate,
      and all remaining amounts held under the Cash Collateral Deposit Letter
      shall be paid to the Company by Laurus Master Fund, Ltd.

            In addition, the Termination Agreement provides that following the
      closing of the Asset Sale, the payment of the Sale Fee to Laurus Master
      Fund, Ltd. and the Company's performance of all of its obligations
      (financial and otherwise) under the Redemption Agreement, as amended by
      the Redemption Agreement Amendment, neither the Company nor Tidel
      Engineering, L.P. or any of their subsidiaries will have any further
      obligations to Laurus Master Fund, Ltd., all of the Warrants shall
      terminate and all liens, claims, encumbrances and security interests held
      by Laurus Master Fund, Ltd. or its transferees or assignees, in the
      Company's and Tidel Engineering L.P.'s, and each of their subsidiaries',
      assets will terminate.
