     7.   Sublessee shall, at its expense, during the term of the Sublease,
maintain public liability insurance and such other insurance coverages in the
amounts required under Article 24 of the Prime Lease in one or more companies
acceptable to Sublessor and Landlord, naming Sublessor, Landlord and Landlord's
manager of the Building as additional insureds.  No policy of insurance obtained
by the Sublessee in compliance with the Prime Lease may be cancelled or
terminated except upon not less than ten (10) days written notice to Sublessor
and Landlord.  True and correct copies of each policy of such insurance, and
renewals thereof, obtained by the Sublessee in compliance with the Prime Lease
shall be delivered to the Sublessor and to Landlord.

     8.   Sublessee agrees to pay a leasing commission in the amount of
$46,179.00 payable in full upon full execution of this Sublease.  United
Properties has agreed under separate agreement that half of said commission is
payable to The O'Neill Real Estate Group, Sublessee's agent.  Sublessee shall
issue two checks of $23,089.50 each, one payable to "United" and the other
payable to "O'Neill".  In no event shall Sublessor have any liability whatsoever
with respect to fees or commissions as a result of this Sublease.

     9.   Immediately, upon the full execution of this Sublease (including the
Consent by the Landlord), Sublessee agrees, at its cost, to complete the
improvements set forth on Exhibit A hereof and upon the completion thereof,
Sublessor shall deliver the Sublet Area to Sublessee for occupancy.  Sublessee
agrees that it shall make no alterations or improvements to the Sublet Area
except as are consented to in writing by Sublessor and by Landlord as to the
nature of such alterations or improvements and the manner of doing the work as
provided for under the Prime Lease.


     10.  On or before Sublessee takes possession of any portion of the Sublet
Area (the "Delivery Date") Sublessee, at its sole cost and expense, shall
deliver to Sublessor a certificate of deposit from a bank (which is reasonably
acceptable to Sublessor) in the principal amount of not less than $27,125.89
(the "BANK CD").  The Bank CD shall be accompanied by an agreement (in form
satisfactory to Sublessor and its legal counsel) pledging the Bank CD jointly to
Sublessor and Landlord as security for the prompt, full and faithful performance
by Sublessee of the terms and provisions of this Sublease Agreement (the "PLEDGE
AGREEMENT").  At the time of delivery of the Bank CD and Pledge Agreement, a
UCC-1 financing statement (in form acceptable to Sublessor, Landlord and its
legal counsel) shall be executed by Sublessee and delivered to Sublessor (the
"FINANCING STATEMENT").

     Notwithstanding any provision to the contrary contained within this
Sublease, upon the occurrence of a default by Sublessee in the payment of rent
or of any other default by Sublessee pursuant to the terms of this Sublease,
Sublessor may foreclose on the Bank CD, including liquidating the Bank CD, by
giving (5) days' written notice to Sublessee.  Sublessee acknowledges and agrees
that the compliance with the notice provisions of this sublease for default plus
the giving of said (5) days' notice prior to foreclosure shall be commercially
reasonable notice to Sublessee.  Sublessor may apply all or a part of the
proceeds from said Bank CD to the payment of the amount of any monetary default.
No foreclosure upon the Bank CD or otherwise converting the Bank CD to cash or
the use of the proceeds thereof shall be deemed a waiver by Sublessor of any
default by Sublessee under any provision of the Sublease, nor shall the use
thereof prevent Sublessor from exercising any other right or remedy provided in
the


                                          2
<PAGE>

Sublease or under any law, nor shall the same be construed as liquidated
damages.  In the event of any such foreclosure and/or conversion to cash,
Sublessor shall not be responsible for and Sublessee hereby indemnifies
Sublessor against any claims resulting from any penalties, fees or charges
imposed by the bank issuing the Bank CD with respect to early withdrawal or
other otherwise imposed in connection with the cashing of the Bank CD.

     Sublessee acknowledges and agrees that if the Bank CD, Pledge Agreement and
Financing Statement are not delivered to Sublessor by the Delivery Date, then
Sublessor may, at its option, terminate this Sublease by giving written notice
to Sublessee.

     IN WITNESS WHEREOF, each of the parties hereto has caused their presence to
be duly executed as of the day and year first above written.

          SUBLESSOR:                         SUBLESSEE:

          RACOTEK, INC.                      GREENTREE SOFTWARE, INC.
          /s/ Ian L. Nemerov                 /s/ Philip D. Wolf

            ----------------------------        ----------------------------

            Secretary and Attorney              Chief Financial Officer


     11.  Sublessor promises and agrees that it will not make any change,
alteration or termination of the underlying Prime Lease, as it affects the space
described in this Sublease without obtaining the prior written approval of the
Sublessee.

     12.  Sublessor and Landlord agree that the Sublessee shall have right to
standard signage for the "Building" including but not limited to inclusion in
the Building's tenant directory and hallway signage sufficient to direct
visitors to Sublessee's Space.  Said signage costs shall be the responsibility
of Sublessee.

     13.  Sublessee agrees not to assign, sublet, license, mortgage or encumber
this Sublease, whether by voluntary act, operation of law or otherwise without
the specific prior written consent of Sublessor and Landlord which consent shall
not be unreasonably withheld or delayed.  Consent by Sublessor and Landlord in
one such instance shall not be a waiver of Sublessor's or Landlord's rights
under this paragraph as to requiring consent for any subsequent instance.  In
the event Sublessee desires to sublet a part or all of the Premises, or assign
this Sublease Agreement, Sublessee shall give written notice to Sublessor and
Landlord at least thirty (30) days prior to the proposed subletting or
assignment, which notice shall state the name of the proposed subtenant or
assignee, the terms of any sublease or assignment documents and copies of
financial information of the proposed subtenant or assignee.  At Landlord's
option, any and all payments by the proposed assignee or sublessee with respect
to the assignment or sublease shall be paid directly to the Landlord.  In any
event no subletting or assignment shall release Sublessee of its obligation to
pay the rent and to perform all other obligations to be performed by the
Sublessee hereunder for the Term of this Sublease.  The acceptance of rent by
Landlord from any other person shall not be deemed to be a waiver by Landlord of
any provision hereof.

                                CONSENT OF LANDLORD

A.   The undersigned Landlord does hereby consent to the above Sublease
provided, however, in no event shall: (i) the Tenant under the Prime Lease be in
any way whatsoever relieved of its obligations to keep and perform promptly each
of the terms, covenants and conditions to be kept or performed by it under the
Prime Lease, or (ii) the terms, covenants or conditions of the Prime Lease be,
in any manner whatsoever, amended or otherwise changed or (iii) the undersigned
be deemed to consent to any further subletting or assignment under the Prime
Lease, or (iv) the acceptance of rent by the Landlord be deemed to create
privity of contract by and between Sublessee and Landlord.  This consent shall
not be effective unless Sublessee delivers to Landlord, prior to taking
possession of the Sublet Area, evidence that Sublessee is in full compliance
with all insurance requirements of the Prime Lease including but not limited to
the requirement that the Landlord and Landlord's manager of the Building are
named as an additional insured in all insurance policies required under the
Prime Lease.

B.   Landlord agrees that so long as Sublessee pays the Minimum Rental and the
Additional Rental as provided for in Paragraph 3 of this Sublease, that the
obligations of Sublessor under the Prime Lease shall be credited in the amounts
provided for in said Paragraph 3.
