                            DEBT CONVERSION AGREEMENT

      This Debt Conversion Agreement (the "Agreement") is made as of 30th day of
December,  2004 by and between  iSecuretrac  Corp., a Delaware  corporation (the
"Company"), and Ken Macke (the "Debt Holder").

                                    RECITALS

      A.  The  Debt  Holder  is  the  holder  of  one or  more  liabilities  and
obligations  of the  Company  which is  described  in  Schedule  1  hereto  (the
"Obligations").  The  outstanding  balance and  accrued  interest of each of the
Obligations is set forth in Schedule 1.

      B. In order to facilitate the Company's ability to raise additional equity
capital,  the Debt Holder and the Company desire to convert the entire principal
balance of the Obligations, but not the accrued interest thereon, into shares of
the Company's  Common Stock, par value ($0.01) per share (the "Common Stock") on
the terms and  conditions  set forth herein and, in connection  therewith to (i)
cancel and forgive the accrued  interest on the  Obligations,  (ii)  release all
claims held by the Debt Holder with respect to the  Obligations  and the payment
of  principal  and  interest  thereon,  and (iii) effect the release any and all
security  interests,  liens and other  encumbrances on the assets of the Company
held by the Debt Holder as security for the Obligations.

      NOW, THEREFORE, in consideration of the mutual promises set forth herein
and of other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, the parties hereto, intending to be legally bound
hereby, do agree as follows:

                                    AGREEMENT

1. Conversion of Obligations, Forgiveness of Interest and Release of Security.

      1.1 Conversion of Obligations into Common Stock.  Subject to the terms and
conditions  of this  Agreement,  at the Closing (as defined  herein) Debt Holder
agrees to cancel  and  terminate  the  Obligations  and to  convert  the  entire
outstanding principal balance of the Obligations (which amounts are set forth in
Schedule  1  hereto)  into  shares  of  Common  Stock at a  conversion  price of
twenty-three  cents ($0.23) per share. In addition,  the Debt Holder agrees that
all accrued and unpaid interest on the Obligations  through the Closing shall be
cancelled and forgiven at the Closing. By converting the Obligations into Common
Stock,  and  cancelling  and  forgiving  the interest  thereon,  the Debt Holder
acknowledges and agrees that the Obligations will be cancelled and terminated in
all  respects  and for all  purposes  and that the Debt Holder will be deemed to
have released all claims held by the Debt Holder with respect to the Obligations
and the payment of principal and interest thereon.

      1.2 Release of Security  Interests.  As a condition to the issuance of the
shares of Common Stock in conversion of the Obligations at Closing,  Debt Holder
hereby cancels,  terminates and releases any and all security  interests,  liens
and  other  encumbrances  held by or for the  benefit  of the Debt  Holder  with
respect to the Obligations in or on the assets,  rights or other property of the
Company, including,  without limitation, all security interests, liens and other
encumbrances on the patents,  trademarks and other intellectual  property rights
of the Company (collectively,  the "Security Interests").  Debt Holder agrees to

release  shall be given full force and effect  according  to each and all of its
express terms and  provisions,  including as well those  relating to the unknown
and unsuspected claims, demands and causes of action hereinabove specified.

3.  Representations  and  Warranties  of the Debt  Holder.  Debt  Holder  hereby
represents and warrants to the Company that:

      3.1  Authorization.  The Debt Holder has full power and authority to enter
into  this  Agreement.  All  corporate  or other  action on the part of the Debt
Holder, and if applicable, its officers, directors, shareholders and/or partners
necessary for the authorization,  execution and delivery of this Agreement,  and
the  performance of all  obligations of Debt Holder  hereunder has been taken or

Holder,  enforceable  in  accordance  with  their  terms,  except as  limited by
applicable  bankruptcy,  insolvency,   reorganization,   moratorium,  fraudulent
conveyance,  or any other laws of general application  affecting  enforcement of
creditors rights generally,  and as limited by laws relating to the availability
of specific performance, injunctive relief, or other equitable remedies.

      3.2  Acquiring  Shares  Entirely  for  Own  Account.  Debt  Holder  hereby
represents that the shares of Common Stock to be issued to Debt Holder hereunder
will be acquired for investment for Debt Holder's own account,  not as a nominee
or agent, and not with a view to the resale or distribution of any part thereof,
and that Debt Holder has no present  intention of selling the same. By executing
this  Agreement,  Debt  Holder  further  represents  that Debt  Holder  does not
presently  have any contract,  undertaking,  agreement or  arrangement  with any
person to sell to any of the shares of Common Stock to be issued hereunder.

      3.3 Accredited Investor.  Debt Holder is an accredited investor as defined
in Rule 501(a) of Regulation D promulgated under the Securities Act and has such
knowledge  and  experience  in financial  and business  matters to be capable of
evaluating the risks and merits of the shares of Common Stock.

      3.4 Disclosure of Information.  The Debt Holder,  if not an officer of the
Company,  has  (i)  had  an  opportunity  to  discuss  the  Company's  business,
management,  financial  affairs and the terms and  conditions of the issuance of
the shares of Common Stock  hereunder  with the Company's  management;  (ii) not
been  offered  shares  of  Common  Stock by any form of  advertisement,  notice,

this Agreement.

      3.5 Restricted Stock.

      (a) The Debt  Holder  understands  that  issuance  of the shares of Common
Stock to the Debt Holder has not been  registered  under the  Securities  Act of
1933, as amended (the "Securities  Act"), by reason of a specific exemption from
the  registration  provisions of the  Securities  Act which depends upon,  among
other things,  the bona fide nature of the investment intent and the accuracy of
the  Debt  Holder's   representations  as  expressed  herein.  The  Debt  Holder
understands  that the shares of Common Stock are "restricted  securities"  under
applicable U.S.  federal and state  securities laws and that,  pursuant to these
laws, Debt Holder must hold the shares of Common Stock indefinitely  unless they
are  registered  with the  Securities  and Exchange  Commission and qualified by
state  authorities,  or an exemption from such  registration  and  qualification
requirements  is  available.  The Debt Holder  further  acknowledges  that if an
exemption from registration or qualification is available, it may be conditioned
on various  requirements  including,  but not limited to, the time and manner of
sale,  the holding  period for the shares of Common Stock,  and on  requirements


                                       3
<PAGE>

relating to the Company  which are outside of such Debt  Holder's  control,  and
which the Company is under no obligation and may not be able to satisfy.

      (b)  Notwithstanding  the  paragraph  (a) of this Section 3.5, the Company
will enter into a registration  rights agreement relating to the registration of
the shares of its Common Stock issued to the Debt Holder under which the Company
will agree to register,  at the Company's  expense,  such Common Stock under the
Securities Act for resale by the Debt Holder.

      3.6 Legend. The Debt Holder understands that the shares of Common Stock
will bear a legend required by the Securities Act or by the Blue Sky laws of any
state to the extent such laws are applicable to the shares represented by the
certificate so legended. The Company may instruct its transfer agent not to
register the transfer of any shares of Common Stock until and unless the
conditions specified in the legend is satisfied.
