                             CONVERTIBLE DEMAND NOTE

     FOR VALUE RECEIVED, ALANCO TECHNOLOGIES,  INC., an Arizona corporation (the
"Maker"),  hereby promises to pay to the order of JOHN A. CARLSON  ("Payee") the
sum of  Twenty-Eight  Thousand  ($28,000.00)  Dollars  (the  "Principal"),  with
interest thereon, on the terms and conditions set forth herein.

     Payments of principal of, interest on and any other amounts with respect to
this  Convertible  Term Note (this "Note") are to be made in lawful money of the
United States of America.

     Principal and accrued  interest of this Note may be convertible into common
stock of the Maker as provided in Section3 below.

     1. Payments.

     (a)  Interest.  This Note shall bear  interest  ("Interest")  on  Principal
amounts outstanding from time to time from and after the date hereof at the rate
of eight (8%) percent per annum; provided,  however, that during the continuance
of any default  hereunder the interest rate hereunder shall be increased by five
hundred  basis  points  (5%) per annum  over the rate that  would  otherwise  be
applicable  hereunder.  All  Interest  shall be  computed  on the  daily  unpaid
Principal  balance of this Note based on a three  hundred  sixty (360) day year,
and shall be payable  monthly in arrears on the first day of each calendar month
commencing June 1, 2010.

     (b)  Principal.  The  outstanding  Principal  of this Note shall be payable
within ten (10) days following written demand therefore.

     2. Prepayment.

     (a) Optional  Prepayment of Principal.  The Maker may prepay any portion of
the Principal from time-to-time upon three (3) days written notice to Payee's.

     (b)  Application of Payments.  Any and all  prepayments  hereunder shall be
applied first to unpaid accrued  Interest on the Principal amount being prepaid,
and then to Principal.

     3. Conversion.

     (a) Optional Conversion.  The Payee may, at its option, upon written notice
to the Maker given at any time and from time to time, convert all or any portion
of the  unpaid  Principal  balance of this Note,  and/or  any  accrued  Interest
thereon,  into shares of common stock of the Maker ("Common Stock"),  at a price
of $0.28 per share of Common Stock (as same may be adjusted from time to time in
accordance  herewith,  the  "Conversion  Price").  The date on which  the  Maker
receives a conversion  election is herein referred to as the "Conversion  Date."
To the extent that the  Principal of this Note is converted  only in part,  then
such  conversion  shall be  treated  as a  prepayment  of the  Principal  amount
converted in accordance with Section 2(a) above.



     (b)  Mechanics  of  Conversion.  Upon  notice to the  Maker of the  Payee's
conversion  election as provided in Section 3(a), the Maker shall, in accordance
with Section 3(c),  issue to the Payee (or to the Payee's  designee(s) set forth
in the  Payee's  conversion  election)  the number of shares of Common  Stock to
which the Payee shall be entitled  upon such  conversion,  and shall  deliver or
cause  to be  delivered  to the  Payee  or  such  designee(s)  the  certificates
representing  such shares of Common Stock.  All shares of Common Stock issued or
delivered upon any conversion hereunder shall, when issued or delivered, be duly
authorized,  validly  issued,  fully  paid  and  nonassessable.  In  lieu of any
fractional  shares to which the Payee would  otherwise  be  entitled,  the Maker
shall pay cash equal to such  fraction  multiplied  by the per share  Conversion
Price.

     (c) Issuance of Common Stock Upon Conversion. Within a reasonable time, not
exceeding  five (5) Business  Days after the  Conversion  Date,  the Maker shall
deliver or cause to be  delivered,  to or upon the written order of the Payee of
this Note so converted,  certificates  representing the number of fully paid and
nonassessable  shares of Common Stock into which this Note has been converted in
accordance  with the provisions of this Section 3. If so requested by the Maker,
the Payee shall,  within a reasonable time (not exceeding five (5) Business Days
after  receipt by the Payee of such  certificates),  surrender  this Note to the
Maker for cancellation,  against delivery of a replacement Note representing the
remaining balance (if any) of this Note which has not been converted. Subject to
the following  provisions of this Section 3, such conversion  shall be deemed to
have  occurred  on the  Conversion  Date,  so  that  the  Payee  or the  Payee's
designee(s) shall be treated for all purposes as having become the record holder
of such shares of Common Stock at such time.

     (d) Taxes on Conversion. The issuance of certificates for shares for Common
Stock upon the conversion of this Note shall be made without charge by the Maker
to the  converting  Payee  for  any  tax in  respect  of the  issuance  of  such
certificates  and such  certificates  shall be issued in the name of, or in such
names as may be directed by, the Payee; provided,  however, that the Maker shall
not be required  to pay any tax which may be payable in respect of any  transfer
involved in the  issuance or  delivery of any such  certificate  in a name other
than that of the Payee,  and the Maker shall not be required to issue or deliver
such certificates  unless or until the person or persons requesting the issuance
thereof  shall  have paid to the Maker the  amount of any such tax or shall have
established to the satisfaction of the Maker that any such tax has been paid.

     (e) Adjustment of Shares.

     (i) Stock Dividends,  Distributions or Subdivisions.  In the event that, at
any time and from time to time from and after the date of this  Note,  the Maker
shall issue  additional  shares of Common Stock (or securities  convertible into
Common Stock) in a stock dividend,  stock  distribution or subdivision paid with
respect to Common Stock, or declare any dividend or other  distribution  payable
in  additional  shares of Common Stock (or  securities  convertible  into Common
Stock)  or effect a split or  subdivision  of the  outstanding  shares of Common
Stock, then,  concurrently with the effectiveness of such stock dividend,  stock
distribution  or  subdivision,  the  then-effective  Conversion  Price  shall be
proportionately  decreased,  and the number of shares of Common  Stock  issuable
upon conversion of this Note shall thus be proportionately increased.

                                       2


     (ii)  Combinations  or  Consolidations.  In the event that, at any time and
from time to time from and after the date of this Note, the  outstanding  shares
of Common  Stock shall be  combined  or  consolidated,  by  reclassification  or
otherwise,  into a lesser number of shares of Common Stock,  then,  concurrently
with the effectiveness of such combination or consolidation,  the then-effective
Conversion Price shall be proportionately increased, and the number of shares of
Common Stock issuable upon conversion of this Note shall thus be proportionately
decreased.

     (iii) Other Dividends or  Distributions.  If the Maker, at any time or from
time to time  after the  issuance  of this  Note,  makes a  distribution  to the
holders of Common Stock which is payable in  securities  of the Maker other than
Common  Stock,  then,  in each such event,  provision  shall be made so that the
Payee shall  receive upon  conversion of this Note, in addition to the number of
shares of Common Stock,  the amount of such  securities of the Maker which would
have been received if the portion of this Note so converted  had been  exercised
for Common Stock on the date of such event, subject to adjustments subsequent to
the date of such event with respect to such  distributed  securities which shall
be on terms as nearly  equivalent as practicable to the adjustments  provided in
this  Section 3(e)(iii)  and all  other  adjustments  under  this  Section 3(e).
Nothing  contained  in this  Section  3(e)(iii)  shall be deemed  to permit  the
payment of any distribution in violation of the Loan Agreement.

     (iv) Merger,  Consolidation  or  Exchange.  If, at any time or from time to
time  after the date of this  Note,  there  occurs  any  merger,  consolidation,
arrangement  or  statutory  share  exchange  of the Maker with or into any other
person or entity, then, in each such event,  provision shall be made so that the
Payee shall  receive upon  conversion of this Note the kind and amount of shares
and other  securities  and  property  (including  cash)  which  would  have been
received  upon  such  merger,  consolidation,  arrangement  or  statutory  share
exchange  by the  Payee  if the  portion  of this  Note so  converted  had  been
converted  into  shares  of  Common  Stock  immediately  prior  to such  merger,
consolidation,  arrangement or statutory share exchange,  subject to adjustments
for events  subsequent  to the  effective  date of such  merger,  consolidation,
arrangement  or statutory  share  exchange with respect to such shares and other
securities  which shall be on terms as nearly  equivalent as  practicable to the
adjustments  provided in this  Section 3(e)(iv)  and all other adjustments under
this Section 3(e). Nothing contained in this Section 3(e)(iv) shall be deemed to
permit any such transaction in violation of the Loan Agreement.

     (v) Recapitalization or  Reclassification.  If, at any time or from time to
time  after the date of this  Note,  the shares of Common  Stock  issuable  upon
conversion  of this  Note are  changed  into the same or a  different  number of
securities   of  any  class  of  the   Maker,   whether   by   recapitalization,
reclassification or otherwise (other than a merger,  consolidation,  arrangement
or statutory share exchange provided for elsewhere in this Section 3(e)),  then,
in each such event, provision shall be made so that the Payee shall receive upon
conversion  of this Note the kind and  amount of  securities  or other  property
which  would  have been  received  in  connection  with  such  recapitalization,
reclassification  or other  change by the Payee if the  portion  of this Note so
converted  had  been  converted  immediately  prior  to  such  recapitalization,
reclassification or change,  subject to adjustments for events subsequent to the
effective date of such  recapitalization,  reclassification or other change with
respect  to such  securities  which  shall be on terms as nearly  equivalent  as
practicable to the adjustments  provided in this  Section 3(e)(v)  and all other
adjustments under this Section 3(e).

                                       3


     (vi) Extraordinary Dividends or Distributions. If, at any time or from time
to time after the date of this Note,  the Maker shall  declare a dividend or any
other  distribution  upon the Common Stock payable otherwise than out of current
earnings,  retained  earnings or earned  surplus and otherwise than in shares of
Common Stock,  then the  Conversion  Price in effect  immediately  prior to such
declaration  shall be reduced by an amount  equal,  in the case of a dividend or
distribution  in cash, to the amount  thereof  payable per share of Common Stock
or, in the case of any other dividend or distribution,  to the value thereof per
share of Common Stock at the time such dividend or distribution was declared, as
determined by the Board of Directors of the Maker in good faith. Such reductions
shall take effect as of the date on which a record is taken for the  purposes of
the subject dividend or distribution,  or, if a record is not taken, the date as
of which the  holders of record of Common  Stock  entitled  to such  dividend or
distribution  are to be determined.  Nothing  contained in this Section 3(e)(vi)
shall be deemed  to permit  the  payment  of any  dividend  or  distribution  in
violation of the Loan Agreement.

     (vii)  Certificate of Adjustment.  Whenever the Conversion Price and/or the
number of shares of Common  Stock  receivable  upon  conversion  of this Note is
adjusted,  the  Maker  shall  promptly  deliver  to the Payee a  certificate  of
adjustment,  setting  forth the  Conversion  Price and/or shares of Common Stock
issuable  after  adjustment,  a  brief  statement  of the  facts  requiring  the
adjustment and the computation by which the adjustment was made. The certificate
of  adjustment  shall  be  prima  facie  evidence  of  the  correctness  of  the
adjustment.

     (viii) Successive Application. The provisions of this Section 3(e) shall be
applicable   successively  to  each  event  described  herein  which  may  occur
subsequent to the date of this Note and prior to the  conversion in full of this
Note.

     (ix)  Fractional  Shares.  No  fractional  shares of Common  Stock shall be
issuable by reason of any adjustments made pursuant to this Section 3(e); and in
lieu of any such  fractional  shares,  the  Maker  shall  pay cash  therefor  in
accordance with Section 3(b) above.

     (f) No  Impairment.  The  Maker  will  not,  by  amendment  of its  Organic
Documents  or through any  reorganization,  transfer  of assets,  consolidation,
merger, dissolution,  issue or sale of securities or any other voluntary action,
avoid or seek to avoid the  observance or  performance of any of the terms to be
observed or  performed  hereunder  but will at all times in good faith assist in
the  carrying out of all the  provisions  of this Section 3 and in the taking of
all such  action as may be  necessary  or  appropriate  in order to protect  the
conversion rights of the Payee against impairment. In the event of any merger or
consolidation  in which the Maker is not the surviving  entity,  the Maker shall
make appropriate  arrangements in order that, upon any subsequent  conversion of
this Note,  the Payee shall become  entitled to receive the same  securities  or
other  consideration that the Payee would have received had such conversion been
made  immediately  prior to the  consummation  of such merger or  consolidation,
subject to further adjustments,  of the type provided in this Note, with respect
to any  events  relating  to any such  securities  occurring  subsequent  to the
consummation of such merger or consolidation.

     (g) Common Stock  Reserved.  The Maker shall at all times  reserve and keep
available out of its authorized but unissued  Common Stock such number of shares
of Common  Stock as shall  from time to time be  sufficient  to effect  the full
conversion of this Note into Common Stock.

                                       4


     4. Events of Default.  The  occurrence a default  under this Note and shall

other action as may be provided for under the law.

     5.  Assignment.  This Note  shall be  binding  upon and shall  inure to the
benefit of the  respective  successors  and  permitted  assigns  of the  parties
hereto,  provided that the Maker may not assign any of its rights or obligations
hereunder without the prior written consent of the Payee.

     6.  Waiver  and  Amendment.  No  waiver  of a right in any  instance  shall
constitute a continuing  waiver of successive  rights,  and any one waiver shall
govern only the particular  matters  waived.  Neither any provision of this Note
nor any  performance  hereunder may be amended or waived  except  pursuant to an
agreement in writing  signed by the party  against whom  enforcement  thereof is
sought.  Except as otherwise  expressly  provided in this Note, the Maker hereby
waives  diligence,   demand,   presentment  for  payment,   protest,   dishonor,
nonpayment,  default,  notice  of any and all of the  foregoing,  and any  other
notice  or  action  otherwise  required  to be given or taken  under  the law in
connection with the delivery, acceptance,  performance,  default, enforcement or
collection  of this Note,  and  expressly  agrees that this Note, or any payment
hereunder,  may  be  extended,  modified  or  subordinated  (by  forbearance  or
otherwise) from time to time,  without in any way affecting the liability of the
Maker. The Maker further waives the benefit of any exemption under the homestead
exemption laws, if any, or any other  exemption,  appraisal or insolvency  laws,
and consents that the Payee may release or surrender, exchange or substitute any
personal  property or other collateral  security now held or which may hereafter
be held as security for the payment of this Note.

     7.  Governing  Law.  This Note shall be  construed in  accordance  with and
governed by the laws of the State of Arizona, except to the extent superseded by
Federal enactments.

     8.  Collection  Costs. In the event that the Payee shall place this Note in

Default,  the  Maker  shall  further  be  liable  to the Payee for all costs and
expenses  (including  reasonable  attorneys'  fees) which may be incurred by the
Payee  in  enforcing  this  Note,  all of  which  costs  and  expenses  shall be
obligations under and part of this Note; and the Payee may take judgment for all
such amounts in addition to all other sums due hereunder.
