         additional  rent an  amount  equal  to  Tenant's  Percentage  share  of
         Operating Expenses and Additional Rent  (collectively,  the "Additional

         the  United  States  of  America,  commencing  on  April  25,  1998 and
         continuing  through December 25, 2000, for the period commencing May 1,
         1998 and  continuing  through  January 31, 2001.  Rent shall be paid to
         Sublessor  at  3400  West  Lake  Avenue,   Glenview,   Illinois  60025,
         Attention: Raymond Pagels or at such other place or places as Sublessor
         may from time to time direct.

4.       SECURITY   DEPOSIT.   Contemporaneously   with  the  execution  hereof,
         Sublessee  shall pay to  Sublessor  the sum of  $8,875.00 as a security
         deposit to secure Sublessee's obligations hereunder.  Said sum shall be
         held by Sublessor as security for the faithful performance by Sublessee
         of all the terms,  covenants and conditions of this Sublease to be kept
         and performed by Sublessee and not as an advance rental deposit or as a
         measure  of  Sublessor's  damage  in case of  Sublessee's  default.  If
         Sublessee  defaults  with respect to any  provision  of this  Sublease,
         Sublessor  may use any part of the Security  Deposit for the payment of
         any rent or any other sum in default,  or for the payment of any amount
         which  Sublessor  may spend or become  obligated  to spend by reason of
         Sublessee's  default, or to compensate  Sublessor for any other loss or
         damage which Sublessor may suffer by reason of Sublessee's  default. If
         any  portion is so used,  Sublessee  shall  within  five (5) days after
         written demand therefor, deposit with Sublessor an amount sufficient to
         restore the  Security  Deposit to its original  amount and  Sublessee's
         failure to do so shall be a material breach of this Sublease. Sublessor
         shall not be required to keep the Security  Deposit  separate  from its
         general funds,  and Sublessee shall not be entitled to interest on such
         deposit.   If  Sublessee  shall  fully  and  faithfully  perform  every
         provision of this Sublease to be performed by it, the Security  Deposit
         or any balance  thereof  shall be returned  to  Sublessee  at such time
         after termination of this Sublease when Sublessor shall have determined
         that all of  Sublessee's  obligations  under  this  Sublease  have been
         fulfilled.

5.       TERM.

     a.  The term of this  Sublease  shall be for a period of  commencing on the
         17th day of April, 1998, and ending on the 31st day of January, 2001.

     b.  If Sublessee,  with Sublessor's consent,  takes possession prior to the
         commencement  of the term,  Sublessee shall do so subject to all of the
         covenants  and  conditions  hereof  and shall  pay rent for the  period
         ending  with the  commencement  of the term at the same  rental as that
         prescribed  for the first  month of the term,  prorated  at the rate of
         1/30th thereof per day.

         Sublessee's  business shall be established and conducted throughout the
         term  hereof  in a first  class  manner.  Sublessee  shall  not use the
         Premises  for, or carry on, or permit to be carried on, any  offensive,
         noisy or dangerous  trade,  business,  manufacture  or  occupation  nor
         permit  any  auction  sale to be  held or  conducted  on or  about  the
         Premises. Sublessee shall not do or suffer anything to be done upon the
         Premises  which  will  cause  structural  injury to the  premiss or the
         building  of which  the same  form a part.  The  Premises  shall not be
         overloaded and no machinery, apparatus or other appliance shall be used
         or operated upon the Premises which will in any manner injure,  vibrate
         or shake the  Premises or the  building  of which it is a part.  No use
         shall  be made  of the  Premises  which  will  in any  way  impair  the
         efficient  operation  of the  sprinkler  system  (if  any)  within  the
         building  containing  the  Premises.  Sublessee  shall  not  leave  the
         Premises  unoccupied  or vacant  during the first twelve (12) months of
         the term. After said twelve (12) month period, Sublessee may vacate the
         Premises only upon prior written notice to Sublessor, said notice to be
         provided  no later than the date which is ninety (90) days prior to the
         date upon which Sublessee  intends to leave the Premises  unoccupied or
         vacant.  Upon  vacating the  Premises,  Sublessee  will be obligated to
         comply with all other terms of the Lease, including without limitation,
         the terms set forth in Paragraph 3 of this  Sublease.  If Sublessee has
         vacated the Premises, Sublessor has the option, in its sole discretion,
         to terminate  this  Sublease  upon thirty (30) days  written  notice to
         Sublessee.  No  musical  instrument  of any sort,  or any noise  making
         device will be operated or allowed upon the Premises for the purpose of
         attracting  trade or otherwise.  Sublessee  shall not use or permit the
         use of the  Premises or any part  thereof  for any  purpose  which will
         increase the existing rate of insurance  upon the building in which the
         Premises are located,  or cause a cancellation of any insurance  policy
         covering  the building or any part  thereof.  If any act on the part of
         Sublessee or use of the Premises by Sublessee  shall cause  directly or

         additional expense shall be paid by Sublessee to Sublessor upon demand.
         No such payment by Sublessee  shall limit  Sublessor in the exercise of
         any other rights or  remedies,  or  constitute a waiver of  Sublessor's
         right to require Sublessee to discontinue such act or use.

7.       SUBLESSEE TO HOLD SUBLESSOR HARMLESS. Sublessor warrants that as of the
         commencement  date of this Sublease,  there will be no uncured  default
         under the Lease. If Sublessee defaults under the Lease, Sublessee shall
         indemnify and hold Sublessor  harmless from all damages  resulting from
         the default.  If Sublessee  defaults in its obligations under the Lease
         and  Sublessor  pays rent to Landlord or  fulfills  any of  Sublessee's
         other  obligations in order to prevent Sublessee from being in default,
         Sublessee  immediately shall reimburse Sublessor for the amount of rent
         or costs  incurred by Sublessor in fulfilling  Sublessee's  obligations
         under this  Sublease,  together with interest on those sums at the rate
