        FOR VALUE  RECEIVED,  the  undersigned,  ILX  INCORPORATED,  an  Arizona
corporation  (the  "undersigned"),  promises  to pay to the  order of  Joseph P.
Martori (as Trustee) ("Payee"),  at Phoenix,  Arizona, or at such other place as
the holder  hereof may from time to time  designate,  the principal sum of Fifty

interest thereon as computed below, as follows:

         Installments of principal and interest in the amount of $3,000 shall be
         payable monthly on the first day of each month  commencing  February 1,
         1995. The entire unpaid  principal  balance,  together with all accrued
         and unpaid interest thereon and other costs payable hereunder, shall be
         paid in full on December 31, 1996.

        Interest shall be charged on the unpaid  principal  balance of this Note
from  January 1, 1995 to the date of  maturity  on a daily  basis for the actual
number of days any  portion of the  principal  is  outstanding,  computed on the
basis of a 360-day  year,  at a per annum rate (the "Note Rate") equal to twelve
percent (12%).

        The undersigned acknowledges that the undersigned has agreed to the rate
of interest represented by the Note Rate, and any additional charges,  costs and
fees arising out of or related to the  transaction of which this Note is a part,
to the extent deemed to be interest under applicable law.

        Each and every payment due under this Note shall be made in lawful money
of the United State of America and in immediately available funds, and when made
shall be first  applied to accrued  costs,  expenses and fees,  if any,  then to
accrued  interest  that has not yet been  added  to  principal,  and then to the
reduction of the  principal  amount of this Note.  This Note may be prepaid,  in
whole or in part,  without  penalty or premium,  provided that each such payment
shall be applied as set forth above.

        At the  option  of  the  holder  hereof,  any  of  the  following  shall
constitute  a  "default"  hereunder,  and,  upon  the  occurrence  of any of the
following,  all obligations hereunder shall, at the option of the holder hereof,
become immediately due and payable, without presentment for payment,  diligence,
grace,  exhibition of this Note, protest,  further demand or notice of any kind,
all of which are hereby expressly  waived:  (i) any sum owing hereunder or under
other  indebtedness of the undersigned to Payee is not paid as agreed;  (ii) any
petition or application  for any form of relief under any provision of Title 11,
United States Code, as amended from time to time (the "Bankruptcy  Code") or any
other law pertaining to  reorganization,  insolvency or readjustment of debts is
filed  by  or  against  the  undersigned,  its  assets  or  affairs;  (iii)  the
undersigned  makes an  assignment  for the benefit of  creditors,  is not paying
debts as they become due, or is granted an order for relief under any chapter of
the Bankruptcy Code; (iv) a custodian,  as defined by the Bankruptcy Code, takes
charge of any property of the undersigned; (v) garnishment,  attachment, levy or
execution is issued  against any of the property or effects of the  undersigned;
(vi) there is a termination, failure to exist or dissolution of the undersigned;
or (vii)  there is any  default  or breach of any  representation,  warranty  or
covenant,  or  there  is  any  false  statement  or  material  omission,  by the
undersigned  under any document  forming part of the  transaction  in respect of
which this Note is made or forming part of any other transaction under which the
undersigned is indebted to Payee.

        The undersigned hereby agrees: (i) to any and all extensions  (including
extensions  beyond the original term hereof) and renewals  hereof,  from time to
time,  without notice, and that no such extension or renewal shall constitute or
be deemed a release of any  obligation of the  undersigned to the holder hereof;
(ii) that any written modification,  extension or renewal hereof executed by the
undersigned  shall constitute a  representation  and warranty of the undersigned
that the unpaid balance of principal, interest and other sums owing hereunder at
the time of such modification,  renewal or extension are owed without adjustment
for offset, counterclaim or other defense of any kind by the undersigned against
Payee;  (iii) that the acceptance by the holder hereof of any performance  which
does not  comply  strictly  with the  terms  hereof  shall not be deemed to be a
waiver or bar of any right of said holder,  nor a release of any  obligation  of
the  undersigned to the holder  hereof;  (iv) to offsets of any sums or property
owed to the  undersigned  by the holder  hereof at any time;  (v) that this Note
shall be governed by the laws of the State of Arizona  applicable  to promissory
notes  made and to be paid in the State of  Arizona;  and (vi) to pay the holder
hereof upon demand any and all costs,  expenses and fees  (including  reasonable
attorneys'  fees) incurred in enforcing or attempting to recover  payment of the
amounts due under this Note,  including  negotiating,  documenting and otherwise
pursuing or consummating modifications,  extensions,  compositions,  renewals or
other  similar  transactions  pertaining  to  this  Note,  irrespective  of  the
existence  of an  event of  default,  and  including  costs,  expenses  and fees
incurred before, after or irrespective of whether suit is commenced,  and in the
event suit is brought to enforce payment hereof,  such costs,  expenses and fees
and all other issues in such suit shall be determined by a court sitting without
a jury.

        This Note is secured by a Security Agreement of even date herewith.

        This Note is executed to be effective as of the date set forth above.
