     B. Sublessee acknowledges that it has thoroughly inspected the Subleased

any warranties to the Sublessee with respect to the quality of construction of
any leasehold improvements or finishes or as to the condition of the Subleased
Premises, whether express, 

                                       2

 
statutorily implied or otherwise, and that Sublessor expressly disclaims any

both Prime Landlord and Sublessor, including, without limitation, approval of

2.03 RELATION TO PRIME LEASE.
     -----------------------

     Except to the extent hereinafter provided, this Sublease is subject and
subordinate to all of the covenants, agreements, terms, provisions, conditions
and obligations of the Prime Lease. Sublessee agrees that all rights and
privileges granted hereunder are subject to the limitations imposed on the
Sublessor by the Prime Lease and that, except as expressly provided herein,
Sublessor is not granting any rights or privileges to Sublessee that are not
expressly granted to Sublessor under the Prime Lease. All of the covenants,
agreements, terms, provisions, conditions, obligations and rules and regulations
of the Prime Lease are incorporated herein, with the same force and effect as if
they were fully set forth herein. Sublessee agrees to be bound by and comply
with the terms of the Prime Lease and to perform Sublessor's obligations with
respect to the Subleased Premises for the benefit of Prime Landlord and
Sublessor, except that:

     (x) Any reference in the Prime Lease to: (i) "Landlord" shall mean Prime
         Landlord; (ii)"Tenant" shall mean

                                       3

 
         Sublessee; and (iii) "Premises" shall mean Subleased Premises.

     (y) In all instances where consent or approval of the Prime Landlord is
         required pursuant to the Prime Lease, the consent or approval of each
         of Prime Landlord and Sublessor shall be required hereunder and
         Sublessor agrees to send to Prime Landlord, at Sublessee Is expense,
         copies of Sublessee's written request for any consents required. In the
         event Sublessor does not notify Sublessee of any objections to a
         request for Sublessor's consent within ten (10) business days of
         Sublessor's receipt of such request, such request shall be deemed
         approved by Sublessor.

The Prime Lease is attached hereto as Exhibit "B". Each party agrees that it
                                      -----------
will not, by its act or omission to act, cause a default under the Prime Lease.
In furtherance of the foregoing, Sublessor and Sublessee hereby confirm, each to
the other, that it is not practical in this Sublease to enumerate all of the
rights and obligations of the various parties under the Prime Lease and
specifically to allocate those rights and obligations in this Sublease.
Accordingly, in order to afford to Sublessee the benefits of this Sublease and
of those provisions of the Prime Lease which by their nature are intended to
benefit the party in possession of the Premises, and in order to protect
Sublessor against a default by Sublessee which might cause a default or event of
default by Sublessor under the Prime Lease:

         A. Subject to the provisions of Section 3.03 herein, without limiting
     the obligations of Sublessor under the Prime Lease, as between Sublessor
     and Sublessee, Sublessor shall pay, when and as due, all Base Rent,
     Additional Rent and other charges payable by Sublessor to Prime Landlord
     under the Prime Lease provided Sublessee shall timely pay all Rent when and
     as due under this Sublease.
     
         B. Sublessee shall perform and observe all terms, affirmative covenants
     and conditions and shall refrain from performing any act which is
     prohibited by the negative covenants of the Prime Lease, where the
     obligation to perform, observe or refrain from performing is by its nature
     imposed upon the party in possession of the Premises and all such
     affirmative covenants and negative covenants shall be deemed incorporated
     herein and shall be performed or observed for the benefit of Sublessor as
     though Sublessor were the landlord thereunder. If practicable, Sublessee
     shall perform affirmative covenants which are also covenants of Sublessor
     under the Prime Lease at least five (5) days prior to the date when
     Sublessor's performance is required under the Prime Lease and shall
     indemnify Sublessor and Guarantor (as defined in the Prime Lease) against
     all claims liabilities, demands, losses, 

                                       4

 
     actions, causes of action, damages, costs and expenses (including
     reasonable attorneys' fees) arising out of Sublessee's failure to perform
     or observe any such terms, covenants or conditions, subject however to all
     the express terms and conditions of this Sublease. Sublessor shall have the
     right, after notice and failure to cure by Sublessee (except in events of
     emergency), but not the obligation to enter the Subleased Premises to cure
     any default by Sublessee under this Sublease.

          C. Provided Sublessee is not in default hereunder and such default is
     continuing uncured, Sublessor shall not agree to an amendment to the Prime
     Lease, unless Sublessor shall first obtain Sublessee's prior written
     approval thereof, not to be unreasonably withheld.

          D. Sublessor shall not be required to make any improvements,
     replacements or repairs of any kind or character to the Premises. Sublessor
     hereby grants to Sublessee the right to receive all of the services and
     benefits with respect to the Subleased Premises which are to be provided by
     Prime Landlord under the Prime Lease; provided, however, Sublessor shall
     have no duty to perform any terms, covenants, conditions to be performed or
     observed by the Prime Landlord under the Prime Lease. For example, and
     without limitation, Sublessor shall not be required to provide the services
     or repairs which the Prime Landlord is required to provide under the Prime
     Lease. Sublessor shall have no responsibility for or be liable to Sublessee
     for any default, failure or delay on the part of Prime Landlord in the
     performance or observance by Prime Landlord of any of the terms, covenants
     and conditions under the Prime Lease, nor shall such default by Prime
     Landlord affect this Sublease or waive or defer the performance of any of
     Sublessee's obligations hereunder except to the extent that such default
     by Prime Landlord excuses performance by Sublessor under the Prime
     Lease. Notwithstanding the foregoing, the parties contemplate that Prime
     Landlord shall, in fact, perform and observe its obligations under the
     Prime Lease and in the event of any default or failure of such performance
     by Prime Landlord, Sublessor agrees that it will, upon notice from
     Sublessee, make demand upon Prime Landlord to perform its obligations under
     the Prime Lease and, provided that Sublessee specifically agrees to pay all
     reasonable costs and expenses of Sublessor and provides Sublessor with
     security reasonably satisfactory to Sublessor to pay such costs and
     expenses, Sublessor will take appropriate legal action to enforce the Prime
     Lease.

          E . Nothing contained in this Sublease shall be construed to create a
     privity of estate of contract between

                                       5

 
     Sublessee and Prime Landlord except as may be created pursuant to Exhibit
     C.

          F.   Notwithstanding anything contained herein to the contrary,
     Sublessee and Sublessor hereby acknowledge that the terms and provisions of
     this Sublease are specifically contingent upon the delivery to Sublessee
     and Sublessor of a fully executed agreement by and between Sublessee and
     Prime Landlord in the same form attached hereto as Exhibit "D".
                                                        ----------
          G.   Without limiting its obligations hereunder, Sublessee hereby
     acknowledges the Prime Landlord's rights as set forth in Sections 10.1,
     12.1, 13.3 and 14.10 of the Prime Lease.

     (except that the Sublessor will forbear from collecting Base Rent for the
     four (4) calendar months commencing with the first full month next
     succeeding the Commencement Date, provided, however, that if the
     Commencement Date is on the first day of a calendar month, such month shall
     be the first calendar month which Sublessor forbears collection, (Sublessee
     shall pay all Additional Rent due for such period), and Sublessee shall
     instead repay such amounts by way of payments to Sublessor, directly, of an
     additional $8,500.00 per month in Base Rent from February 1, 1998 to
     January 31, 1999)

                                       6

 
     3.02  ADDITIONAL RENT.  If and to the extent that Sublessor is obligated to
           ---------------
 pay Additional Rent under the Prime Lease, Sublessee shall, effective as of the
 Commencement Date, pay to Sublessor such Additional Rent (to the extent such
 Additional Rent is attributable to events occurring during the Term of this
 Sublease). Such payment shall be due from Sublessee to Sublessor at least five
 (5) days prior to the date upon which Sublessor's payment of such Additional
 Rent is due to the Prime Landlord, provided that Sublessee shall have been
 billed therefor at least ten (10) days prior to such due date (which bill shall
 be accompanied by a copy of Prime Landlord's bill and other material furnished
 to Sublessor in connection therewith). If any such payments are estimated and
 paid monthly by Sublessor under the Prime Lease, Sublessee shall pay its share
 of the estimated monthly payments on the first (1st) day of every month in
 which a payment is due by Sublessor under the Prime Lease. As of the date
 hereof, Sublessee's share of such expenses is 100%, subject to adjustment as
 provided in Section 1.8 and 2.2 of the Prime Lease.

     Section 2.2 of the Prime Lease provides for an adjustment of the monthly
 operating Expenses actually paid by Prime Landlord during said year with
 Sublessor's pro rata share of operating expenses actually paid with respect to
 such year. To the extent Prime Landlord pays Sublessor any overpayment with
 respect to Sublessor's pro rata share of operating expenses, Sublessor shall
 remit to Sublessee such overpayment. Likewise, to the extent Sublessor is
 obligated to pay any deficiency in the payment of Sublessor's pro rata share of
 operating expenses, Sublessee shall, within five (5) days after written demand
 therefor by Sublessor, pay to Sublessor such deficiency.

     3.03  SUBLESSEE'S PAYMENT OF RENT DIRECTLY TO PRIME LANDLORD.  Sublessee
           ------------------------------------------------------ 
 shall make all Rent, including Base Rent and Additional Rent, payments due
 under this Sublease directly to Landlord at Landlord's address set forth in the
 Prime Lease, except that Sublessor agrees to pay to Prime Landlord the Base
 Rent due for the four (4) calendar months commencing with the first full month
 next succeeding the Commencement Date, and Sublessee agrees to pay the
 additional $8,500.00 per month rent due during the year 1998 directly to the
 Sublessor. Upon Sublessee's receipt of a notice from Sublessor directing Rent
 to be paid to Sublessor, Sublessee shall thereafter make all such payments
 directly to the Sublessor. Except as provided in the Prime Landlord and
 Sublessee NonDisturbance Agreement, in the event the Sublessee fails to pay any
 Rent, after notice and within the time set forth in the notice, thereafter,
 until Sublessee has cured such failure to pay Rent, all Rent due under the
 Sublease shall be paid directly to Sublessor at the address set forth in
 Section 1.01 B herein.

     4.01  SECURITY DEPOSIT.  The Sublessee has delivered to Sublessor a
           ----------------
 security deposit in the amount of $150,528.00 as a security deposit for the
 full and faithful performance of each and every provision of this Sublease to
 be performed by Sublessee, on the understanding that: (a) the Security Deposit
 or any portion thereof not previously applied, or from time to time, such one
 or more portions thereof, may be applied to cure any default that may then
 exist, without prejudice to any other remedy or remedies which Sublessor may
 have on account thereof, and upon such application Sublessee shall pay
 Sublessor on demand the amount so applied which shall be added to the Security
 Deposit so the same may be restored to its original amount; (b) should the
 Prime Lease be assigned by Sublessor, the Security Deposit or any portion
 thereof not previously applied may be paid to the Sublessor's assignee and if
 the same is paid as aforesaid, Sublessee hereby releases Sublessor from any and
 all liability with respect to the Security Deposit and/or its application or
 return; (c) if permitted by law, Sublessor or its successor shall not be
 obligated to hold the Security Deposit as a separate fund, but on the contrary
 may commingle the same with its other funds; (d) if Sublessee shall faithfully
 perform and observe all of the terms, covenants, and conditions in this
 Sublease and in the Prime Lease set forth and contained on the part of
 Sublessee to be fulfilled, kept, performed and observed, the sum deposited or
 the portion thereof not previously applied, shall be returned to Sublessee
 without interest no later than thirty (30) days after the expiration of the
 Term of this Sublease or any renewal or extension thereof, provided Sublessee
 has vacated the Premises and surrendered possession thereof to Sublessor at the
 expiration of the Term or any extension or renewal thereof as provided herein;
 (e) in the event that Sublessor terminates this Sublease or Sublessee's right
 to possession by reason of a Default by Sublessee, Sublessor may apply the
 Security Deposit against damages suffered to the date of such termination
 and/or may retain the Security Deposit to apply against such damages as may be
 suffered or shall accrue thereafter by reason of Sublessee's default; (f) in
 the event any bankruptcy, insolvency, reorganization or other creditor-debtor
 proceedings shall be instituted by or against Sublessee, or its successors or
 assigns, the Security Deposit shall be deemed to be applied first to the
 payment of any Rent due Sublessor for all periods prior to the institution of
 such proceedings, and the balance, if any, of the Security Deposit may be
 retained or paid to Sublessor in partial liquidation of Sublessor's damages.
 Sublessor's parent corporation, Globelle Corporation, an Ontario corporation,
 ("Guarantor") has executed the Sublease solely for the purpose of agreeing to
 guaranty the performance of the Sublessor with respect to the Security Deposit.
 The Guarantor hereby submits to personal jurisdiction in the State of Minnesota
 for the enforcement of this Guaranty and waives any and all personal rights to
 object to such jurisdiction for the purposes of litigation to enforce this
 Guaranty. In the event such litigation is commenced at any time when Guarantor
 is not permanently domiciled in the State of 

                                       8

 
 Minnesota, Guarantor agrees that service of process may be made and personal
 jurisdiction over Guarantor obtained, by service of a copy of the summons,
 complaint and other pleadings required to commence such litigation upon
 appointed Agent for Service of Process in the State of Minnesota, which Agent
 Guarantor hereby designates to be:

 Mary L. Galvin, Bassford, Lockhart, Truesdell & Briggs, Lawyers, 3550

 Guarantor agrees that this appointment of an agent for service of process is
 made for the mutual benefit of Guarantor and Sublessee and may not be revoked
 without Sublessee's consent. Guarantor hereby agrees and consents that any such
 service of process upon such agent shall be taken and held to be valid personal
 service upon Guarantor whether or not Guarantor shall be then physically
 present, residing within, or doing business within the State of Minnesota, and
 that any such service of process shall be of the same force and validity as if
 service were made upon Guarantor when physically present, residing within, or
 doing business in the State of Minnesota. Guarantor waives all claim of error
 by reason of any such service. Guarantor hereby consents to the exclusive
 jurisdiction of either the District Court of Hennepin County, Minnesota, or the
 United States District Court for Minnesota, in any action, suit or proceeding
 which Owner may at any time wish to file in connection with this Guaranty or
 any related matter. Guarantor hereby agrees that an action, suit or proceeding
 to enforce this Guaranty shall be brought in any State or Federal Court in the
 State of Minnesota and hereby waives any objection which Guarantor may have to

 Court; provided, however, that the provisions of this Section shall not be
 deemed to preclude Sublessee from filing any such action, suit or proceeding in
 any other appropriate forum.

     (2)  If a party fails in the prompt and full performance of any other
provisions of this Sublease (including, without limitation, the terms of the
Prime Lease which have been incorporated herein) other than the nonpayment of
Rent or other payments due under this Sublease, and does not cure such failure
within ten (10) days after written demand from the other party that the failure
be cured (unless the failure involves a hazardous

                                      11 

 
condition, which shall be cured forthwith or as quickly as reasonably possible);
or

creditors; or

     (6)  Sublessee shall do or permit to be done any act which results in a
lien being filed against the Subleased Premises.

     In the event that an order for relief is entered in any case under Title
11, U.S.C. (the "Bankruptcy Code") in which the Sublessee is the debtor and: (A)
Sublessee as debtor in possession, or any trustee who may be appointed in the
case (the "Trustee") seeks to assume the Sublease, then Sublessee, or Trustee,
if applicable, in addition to providing adequate assurance described in
applicable provisions of the Bankruptcy Code, shall provide adequate assurance
to Sublessor of Sublessee's future performance under the Sublease by depositing
with Sublessor a sum equal to the lesser of twenty-five per cent (25%) of the
rental and other charges due for the balance of the Sublease term of six (6)
months' rent ("Security"), to be held (without an allowance for interest
thereon) to secure Sublessee's obligations under the Sublease, and (B)
Sublessor, or Trustee, if applicable, seeks to assign the Sublease after
assumption of the same, then Sublessor, in addition to providing adequate
assurance described in applicable provisions of the Bankruptcy Code shall
provide Adequate assurance to Sublessor of the proposed assignee's future

or shall be construed to express or imply, that Sublessor is consenting to
assumption and/or assignment of the Sublease. Neither Sublessee nor any Trustee
shall conduct or permit the conduct of any "lien," "bankruptcy," "going out of
business" or auction sale in or from the Subleased Premises.

Then, and in any such event (sometimes referred to as an "Event of Default")
such party ("Defaulting party") shall be in default.

     10.02 DEFAULT BY SUBLESSEE. Upon a default by Sublessee, Sublessor may
           --------------------

possession of the Subleased Premises.

     10.03 DEFAULT OF SUBLESSOR. Upon a default by Sublessor, Sublessee may
           --------------------

as Sublessor is not in default under the Prime Lease for a monetary amount in
excess of $5,000, Sublessee shall have no right to terminate this Sublease.

11.  SURRENDER OF SUBLEASED PREMISES. Upon any expiration or termination of this
     -------------------------------
Sublease or termination of Sublessee's right of possession of the Subleased
Premises, or any part thereof, Sublessee shall surrender and vacate the
Subleased Premises immediately and surrender the Subleased Premises to
Sublessor, including the alterations, additions, improvements, equipment, and
fixtures requested by Sublessor to remain on the Subleased Premises other than
Sublessee moveable trade fixtures, in good condition and repair, shall remove
all alterations, additions, improvements and fixtures not requested by Sublessor
to remain on the Subleased Premises and shall repair all damage to the Subleased
Premises caused by such removal prior to the Expiration Date. Any property not
removed from the Subleased Premises upon expiration or termination hereof shall,
subject to the rights of Prime Landlord under the Prime Lease, be conclusively
presumed to have been abandoned by Sublessee, and Sublessor, or Prime Landlord
may, at its option, retain, store and/or dispose of such property at Sublessee's
expense. All such property shall, at Sublessor's or Prime Landlord's option, be
conclusively deemed to have been conveyed to Sublessor by Sublessee as if by
bill of sale without payment by Sublessor.

Landlord, in the same manner required for naming Prime Landlord as provided
therein. Sublessee shall furnish Sublessor a certificate of Sublessee's
insurance required hereunder not later than Sublessee's taking possession of the
Subleased Premises. Each party hereby waives claims against the other for
property damage provided such waiver shall not invalidate the waiving party's
property insurance; each party shall attempt to obtain from its insurance
carrier a waiver of its right of 

                                      13

 
 subrogation. Sublessee hereby waives claims against Prime Landlord and
 Sublessor for property damage to the Subleased Premises or its contents if and
 to the extent that Sublessor waives such claims against Prime Landlord under
 the Prime Lease. Sublessee agrees to obtain, for the benefit of Prime Landlord
 and Sublessor, such waivers of subrogation rights from its insurer as are
 required of Sublessor under the Prime Lease. Sublessor agrees to use reasonable
 efforts in good faith to obtain from Prime Landlord a waiver of subrogation
 rights in Prime Landlord's property insurance if and to the extent that Prime
 Landlord waives such claims against Sublessor under the Prime Lease or is
 required under the Prime Lease to obtain such waiver of subrogation rights. 

 14. HAZARDOUS SUBSTANCES.
     --------------------

     14.01   Representation By Sublessor. Sublessor represents that to the

 Conservation and Recovery Act, 42 U.S.C. (SS)960, et seq., in, on, or about the
 Subleased Premises. If subsequent to the date Sublessee accepts possession of
 the Subleased Premises it is determined that there are any Hazardous Materials
 (as defined below) in the Subleased Premises which were installed after
 Sublessor obtained possession of the Subleased Premises under the Prime Lease,
 and such Hazardous Materials are required by applicable federal, state or local
 law to be removed, encapsulated or otherwise treated ("Remediated"), Sublessor,
 at Sublessor's expense, shall as soon as practicable after notice thereof from
 Sublessee, remediate said Hazardous Materials as Sublessor deems appropriate so
 that all applicable federal, state and local laws are complied with. Such
 Remediation shall be Sublessee's sole remedy on account of such Hazardous
 Materials.

     14.02   REPRESENTATION BY SUBLESSEE. Sublessee shall not transport, use,
             ---------------------------
 store, maintain, generate, manufacture, handle, dispose, release or discharge
 any "Hazardous Material" (as defined below) upon or about the Subleased
 Premises or permit Sublessee's employees, agents, contractors, invitees and
 other occupants of the Subleased Premises to engage in such activities upon or
 about the Subleased Premises. Sublessee shall promptly notify Sublessor of: (i)
 any enforcement, cleanup or other regulatory action taken or threatened by any
 governmental or regulatory authority with respect to the presence of any
 Hazardous Material on the Subleased Premises or the migration thereof from or
 to other property, (ii) any demands or claims made or threatened by any party
 relating to any loss or injury resulting from any Hazardous Material on the
 Subleased Premises, (iii) any release, discharge or nonrouting, improper or
 unlawful disposal or transportation of any Hazardous Material on or from the
 Subleased Premises or in violation of this Section, and (iv) any matters where

                                      14

 
give a notice to any governmental or regulatory authority respecting any
Hazardous Material on the Subleased Premises. Sublessor and Prime Landlord shall
have the right (but not the obligation) to join and participate, as a party, in
any legal proceedings or actions affecting the Subleased Premises initiated in
connection with any environmental, health or safety law. The term "Hazardous
Material" for purposes hereof shall mean any chemical, substance, material or
waste or component thereof which is now or hereafter listed, defined or
regulated as a hazardous or toxic chemical, substance, material or waste or
component thereof by any federal, state or local governing or regulatory body
having jurisdiction, or which would trigger any employee or community "right-to-
know" requirements adopted by any such body, or for which any such body has
adopted any requirements for the preparation or distribution of an Material
Safety Data Sheet.

     14.03  USE OF HAZARDOUS MATERIAL. If any Hazardous Material is released,
            -------------------------
discharged or disposed of by Sublessee or any other occupant of the Subleased
Premises, or their employees, agents or contractors, on or about the Subleased
Premises in violation of the foregoing provisions, Sublessee shall immediately,
properly and in compliance with applicable Laws clean up and remove the
Hazardous Material from the Subleased Premises and any other affected property
and clean or replace any affected personal property (whether or not owned by
Sublessor or Prime Landlord), at Sublessee's expense (without limiting
Sublessor's other remedies therefor). Such clean up and removal work shall be
subject to Sublessor's and Prime Landlord's prior written approval (except in
emergencies), and shall include, without limitation, any testing, investigation,
and the preparation and implementation of any remedial action plan required by
any court or governmental body having jurisdiction or reasonably required by
Sublessor or Prime Landlord. If Sublessor, Prime Landlord or any Lender or
governmental body arranges for any tests or studies showing that this Section
has been violated, Sublessee shall pay for the costs of such tests. If any
Hazardous Material is released, discharged or disposed of on or about the
Subleased Premises and such release, discharge or disposal is not caused by
Sublessee or other occupants of the Subleased Premises, or their employees,
agents or contractors, such release, discharge or disposal shall be deemed
casualty damages to the extent that the Subleased Premises are affected thereby;
in such case, Sublessee and Sublessor shall have the obligations and rights
respecting such casualty damage provided under such Section 15 of this Sublease.

15.  DAMAGE BY FIRE OR OTHER CASUALTY. If (i) all or any portion of either the
     --------------------------------
Subleased Premises are damaged by fire or other casualty, (ii) such event gives
Sublessor the right to terminate the Prime Lease or Prime Landlord the right to
terminate the Prime Lease, and (iii) either Sublessor (Sublessor shall not
exercise such right without the written consent of Sublessee) or Prime Landlord
exercises such right; then this Sublease shall terminate

                                      15

 
 in accordance with the provisions of the Prime Lease and all Base Rent and
 Additional Rent shall be apportioned in accordance with the provisions of the
 Prime Lease. If Sublessor or Prime Landlord is not entitled to terminate or
 does not exercise their respective right of termination with respect to a fire
 or other casualty, then (i) this Sublease shall continue in full force and the
 Subleased Premises shall be repaired or restored in the same manner and under
 the same conditions for repair and restoration as provided and required in the
 Prime Lease and (ii) Base Rent and Additional Rent shall abate in the same
 manner and for such period as Rent abates under the Prime Lease.

 public use or purpose or conveyed under threat of such condemnation, (ii) such
 event gives Prime Landlord the right to terminate the Prime Lease or Sublessor
 (Sublessor shall not exercise such right without the prior written consent of
 Sublessee) the right to terminate the Prime Lease, and (iii) either Sublessor
 or Prime Landlord exercises such right; then this Sublease shall terminate in
 accordance with the provisions of the Prime Lease, and all Base Rent and
 Additional Rent shall be apportioned in accordance with the provisions of Prime
 Lease.
