Subtenant and Subtenant hereby takes and hires from Sublandlord the Subleased
Premises, on the terms and conditions set forth below:

         I.   DEFINED TERMS. All terms defined in the Prime Lease and used

Term for one (1) twenty (20) month period (the "Option Term") exercisable by

         IV.   DELIVERY. The Subleased Premises shall be delivered to Subtenant,
broom-clean and free of all occupants but otherwise "as-is, where-is and with

therefore covenants and agrees that its payments of Basic Rent hereunder shall
be paid to Sublandlord at least two (2) business days prior to the first of each
calendar month. Subtenant shall deliver $9,000.00 as payment for the first
month's rent upon execution of this Sublease.

and normal monitoring. Subtenant shall buy from Sublandlord access cards for
Subtenant's employees at a charge of Nine and 00/100 Dollars ($9.00) per card.
Replacement cards shall be charged at the same rate as new cards. Subtenant
shall also pay to Sublandlord as additional rent the costs for any additional
administration of the ADT System by Sublandlord at the rate of Seventy and
00/100 Dollars ($70.00) per hour.

         VIII. USE. The Subleased Premises shall be used and occupied for
general business office purposes and for no other use or purpose.

         IX. SECURITY DEPOSIT. Upon execution hereof, Subtenant has delivered to
Sublandlord the sum of $9,000.00 (one (1) month of Basic Rent) ("Subtenant's
Security Deposit"), such sum to be held by Sublandlord as security for the
performance of Subtenant's obligations under this Sublease. Upon the occurrence
of any default by Subtenant hereunder after expiration of any applicable grace
or cure periods, Subtenant agrees that Sublandlord may apply all or any part of
Subtenant's Security Deposit, together with accrued interest, if any, to any
obligation of Subtenant hereunder. Such application shall not excuse the default
of Subtenant hereunder. If all or any portion of Subtenant's


                                      -2-



Security Deposit is applied by Sublandlord against any of Subtenant's
obligations hereunder, Subtenant shall promptly restore Subtenant's Security
Deposit to its original amount. Interest on Subtenant's Security Deposit shall
in all instances be retained by Sublandlord. Subtenant's Security Deposit will
be returned to Subtenant within thirty (30) days of termination of this
Sublease.

         X.   PRIME LEASE. Subtenant agrees that it will do nothing in, on or
about the Subleased Premises which would result in the breach by Sublandlord of
its undertakings and obligations under the Prime Lease. Except for the following
provisions, this Sublease shall be subject to and on all of the terms and
conditions as are contained in the Prime Lease and the provisions of the Prime
Lease are hereby incorporated into this Sublease as if Sublandlord were the
landlord thereunder and Subtenant the tenant thereunder:

         The defined economic terms for "Basic Rent," "Security Deposit,"
"Tenant Allowance," "Term," "Premises" and the like are inapplicable;

              A.     Section 3.2 of the Prime Lease (relating to escalation
                     payments) are inapplicable;

              B.     Section 31 of the Prime Lease (relating to brokers) is
                     inapplicable;

              C.     Exhibit B to the Prime Lease (relating to construction of
                     the Original Premises) is inapplicable.

         Where appropriate, references to "Landlord" in the Prime Lease shall be
deemed to mean "Sublandlord" hereunder and references to "Tenant" in the Prime
Lease shall be deemed to mean "Subtenant" hereunder, it being understood and
agreed that Sublandlord will not be acting as, or assuming any of the
responsibilities of, Prime Landlord, and all references in the Prime Lease to
Landlord-provided services or Landlord insurance requirements, and any other
references which by their nature relate to the owner or operator of the
Building, rather than to a tenant of the Building subleasing space to a
subtenant, shall continue to be references to Prime Landlord and not to
Sublandlord.

         XI.  SUBTENANT'S COVENANTS. Subtenant covenants to Sublandlord to
perform all of the covenants and obligations to be performed by Sublandlord as
Tenant under the Prime Lease as the same relate to the Subleased Premises and to
comply with this Sublease and the applicable provisions of the Prime Lease, as
modified by this Sublease, in all respects. If Subtenant shall fail to make any
payment or perform any act required to be made or performed by Subtenant under
the Prime Lease pursuant to Subtenant's assumption of Sublandlord's obligations
thereunder as they relate to the Subleased Premises, and such default is not
cured by Subtenant by the first to occur of (i) one-half of the period specified
in the Prime Lease for curing such default, or (ii) five (5) days prior to the
expiration of such Prime Lease cure period, Sublandlord, without waiving or
releasing any obligation or default hereunder, may (but shall be under no
obligation to) make such payment or perform such act for the account and at the
expense of Subtenant, and may take any and all such actions as Sublandlord in
its sole discretion deems necessary or appropriate to accomplish such cure. If
Sublandlord shall reasonably incur any expense in remedying such default,
Sublandlord shall be entitled to recover such sums upon demand from Subtenant as
Additional Rent under this Sublease.

                                      -3-




         XII.   SUBLANDLORD'S COVENANTS. Sublandlord covenants to Subtenant to
perform all of the terms and provisions required of it under the Prime Lease and
to promptly pay when due all rents due and accruing to Prime Landlord under the
Prime Lease. Sublandlord will use reasonable efforts to enforce on behalf of
Subtenant Sublandlord's rights under the Prime Lease. Nothing contained in this
Sublease shall be construed as a guarantee by Sublandlord of any of the
obligations, covenants, warranties, agreements or undertakings of Prime Landlord
in the Prime Lease, nor as an undertaking by Sublandlord to Subtenant on the
same or similar terms as are contained in the Prime Lease.

         XIII.  INDEMNIFICATION. Subtenant and Sublandlord shall indemnify and
hold the other party harmless from and against any and all claims, demands
suits, judgments, liabilities, costs and expenses, including reasonable
attorney's fees, arising out of or in connection with such party's use and
possession of the Subleased Premises, or arising out of the failure of such

condition of this Sublease or of the Prime Lease to be performed by the
respective parties hereunder.

         XIV.   ASSIGNMENT AND SUBLETTING. Subtenant shall be allowed to assign
this Sublease or sublet the Subleased Premises in whole or in part, only with

terms of Section 14 of the Prime Lease. Any excess consideration derived from
said assignment or sublet shall be divided pursuant to the terms of Section 14.3
of the Prime Lease.

         XV.    BROKERS. Each of Sublandlord and Subtenant represents and
warrants to the other that it has not dealt with any broker in connection with
this Sublease other than BT Commercial Real Estate (the "Broker"), and each
agrees to indemnify, defend and hold the other harmless from and against any
breach of said representation and warranty. Sublandlord shall be responsible for
any commission to be paid to the Broker pursuant to a separate agreement.

         XVI.   INSURANCE. Subtenant shall comply with all insurance 
requirements of the Prime Lease, including the provisions of Section 11 thereof.
Subtenant shall deliver to Sublandlord certificates which evidence such 
insurance prior to the Sublease Term Commencement Date, and thereafter as 
required under the Prime Lease, and shall name in all such insurance policies 
both the Prime Landlord and Sublandlord as additional insureds thereunder.

         XVII.  PARKING. Subtenant shall be entitled to the unassigned and
non-exclusive use of seventeen (17) parking spaces in the Parking Facility, in
