      MASTER TERMS AND CONDITIONS - PLEASE READ CAREFULLY BEFORE SIGNING

1. ENTIRE AGREEMENT. This Lease which includes the provisions on the reverse
   side hereof and any other Schedule(s) made a part hereof by the parties,
   constitute the entire agreement between Lessor and Lessee.

2. TERM/RENT. Upon acceptance hereof, Lessor agrees to lease to Lessee the
   "Equipment" indicated in the Schedule(s) to be annexed hereto for the "Basic
   Term" indicated on said Schedule(s). Lessee promises to pay to Lessor, or
   order, the aggregate Basic Rent as provided on said Schedule(s), and all
   other payments provided herein, in Lessor's corporate office. The Term and
   the first rental period and monthly payment for the Equipment will commence
   on the first day of the month following Lessee's acceptance of the Equipment
   and shall continue for the number of months indicated on said Schedule(s). In
   addition, Lessee shall pay to Lessor an interim rent payment equal to a
   prorata amount of the monthly rent payment for each day from the date of
   acceptance of the Equipment until the first day of the following month. The
   Basic Rent, shall be adjusted and increased by Lessor to cover any and all
   sales, use or rental taxes imposed from time to time upon Lessor, the Basic
   Rent, and/or the Equipment. 
   Lessee understands and agrees that neither the supplier nor any marketing
   officer is an agent of Lessor. No such supplier nor marketing officer is
   authorized to alter, waive or add to any term or condition of this Lease, and
   no representation as to the Equipment, Lease or any other matter by any
   supplier or any marketing officer shall in any way affect Lessee's duty to
   pay Basic Rent, and/or to perform its other obligations as set forth herein.
   LESSEE SHALL PAY AND PERFORM THIS LEASE WITHOUT NOTICE, DEMAND, OFFSET,
   DEDUCTION, DEFENSE OR DEFERMENT, AND ANY CLAIMS BY LESSEE AGAINST LESSOR
   SHALL ONLY BE ASSERTED IN AN INDEPENDENT ACTION. THIS LEASE CANNOT BE
   CANCELLED OR TERMINATED BY LESSEE EXCEPT AS PROVIDED HEREIN.

3. DISCLAIMERS. LESSOR, NOT BEING THE MANUFACTURER OR SUPPLIER OF ANY OF THE
   EQUIPMENT, HAS NOT MADE AND DOES NOT MAKE TO LESSEE ANY REPRESENTATION,
   WARRANTY OR COVENANT, EXPRESS OR IMPLIED, WITH RESPECT TO THE EQUIPMENT, OR
   THE DELIVERY, INSTALLATION OR TIMELINESS THEREOF, NOR WITH RESPECT TO THE
   EQUIPMENT'S MANUFACTURE, DESIGN, CONDITION, FITNESS FOR USE, OR
   MERCHANTABILITY, AND ALL EQUIPMENT SHALL BE ACCEPTED AND LEASED BY LESSEE "AS
   IS". IN NO EVENT SHALL LESSOR BE LIABLE FOR ANY SPECIAL, CONSEQUENTIAL OR
   INCIDENTAL DAMAGES TO LESSEE AS A RESULT OF THIS LEASING TRANSACTION. LESSEE
   AGREES ALL SUCH CLAIMS SHALL BE ASSERTED AND/OR SETTLED DIRECTLY WITH THE
   SUPPLIER(S) AND NO SUCH CLAIMS SHALL BE ASSERTED AGAINST LESSOR.

4. EQUAL OPPORTUNITY. NORSTAN shall observe its responsibilities under Executive
   Order 11246, as amended and the regulations at 41 CFR Parts 60-1 through 60-
   80, and Sections 402/503 and the regulations at 41 CFR Parts 250 and 60-741.

5. EQUIPMENT SELECTION/ORDERING/ACCEPTANCE. Lessee has selected the
   suppliers, type, design and quality of Equipment and hereby requests Lessor
   to acquire and lease the same upon the terms hereof. LESSEE ASSUMES THE
   RESPONSIBILITY FOR DELIVERY, INSPECTION AND ACCEPTANCE OF THE EQUIPMENT AND
   LESSOR SHALL NOT BE LIABLE OR RESPONSIBLE FOR ANY DELAY OR FAILURE OF
   DELIVERY OF SAID ORDERED EQUIPMENT. LESSEE ASSUMES ALL RISKS AND OBLIGATIONS
   TO ANY SUPPLIER ON ACCOUNT OF NONACCEPTANCE OF THE EQUIPMENT OR TERMINATION
   OF THIS LEASE. So long as Lessee is not in default, Lessee may, at its
   expense, enforce damage and warranty claims to its interest directly against
   the supplier(s), and the same shall be deemed part of the Equipment and
   Collateral described in Section 10 hereof.

6. LOCATION/INSPECTION. The location of the Equipment shall be as indicated
   hereon (or on its Schedule). The location shall not be changed without
   Lessor's prior written consent. Lessee shall permit Lessor, its agents, and
   potential purchasers of the Equipment, access at reasonable times to inspect
   the Equipment, and observe its use and condition.

7. LIENS AND ENCUMBRANCES. Lessee will at all times protect and defend, at its
   own cost and expense, the interest and priority of Lessor and keep the
   Equipment (and additions or attachments of Lessee thereto, if any) free and
   clear from any and all claims, liens and processes and other encumbrances.

8. SECURITY INTEREST. Lessor and Lessee intend this transaction to be a leasing
   transaction only, but to the extent, at any time or from time to time, this
   Lease is construed or asserted to be a transaction intended as a security,
   Lessor retains and/or Lessee hereby grants to Lessor a security interest in
   and to all the Equipment, the proceeds of any contracts, sale, assignment,
   lease or sub-lease thereof, any insurance proceeds, and any other rights of
   Lessee in and to the Equipment, the Lease and/or their proceeds. No title
   equity or right in or to the Equipment shall pass to Lessee except in
   accordance with the terms hereof. Lessee agrees that Lessor is authorized to
   file a copy of this Lease as a financing statement and file it or other
   financing statements or amendments thereto with or without the signature of
   Lessee with respect to any or all of the Equipment and, if Lessee's signature
   is required thereon by law, Lessee irrevocable appoints Lessor as Lessee's
   attorney-in-fact to execute any such financing statements.

9. ASSIGNMENT/SUBLEASE. Lessee shall not sell, transfer, assign, sublease,
   convey, encumber or pledge its interest in and to this Lease, any Schedule or
   the Equipment, and any such sale, transfer, assignment, sublease, conveyance,
   encumbrance or pledge, whether by operation of law or otherwise, without the
   prior written consent of Lessor, shall be void. Lessor, its successor and
   assigns, may sell or assign this Lease or any Lease Schedule and/or grant
   security interest therein or security interest in the Equipment, in whole or
   in part, with or without notice to Lessee. The provisions of this Lease shall
   be binding upon any successors and any permitted assigns of Lessor and
   Lessee.

              THIS LEASE IS NOT BINDING UNTIL ACCEPTED BY LESSOR

10. USE AND MAINTENANCE. Lessee, at Lessee's expense, agrees to use the
    Equipment in a careful and proper manner, and to comply with and conform to
    all federal, state, municipal, and other laws, ordinances and regulations
    applicable in any way to the inspection, possession, use or maintenance of
    the Equipment. Lessee agrees, at its expense, (1) to maintain the Equipment
    in top condition, ordinary wear and tear excepted, and (2) to timely repair
    and/or replace any failed or damaged part thereof so that the Equipment
    remains at all times in full repair, operating order, and safe working
    condition.

11. ALTERATIONS. Lessee shall, at its sole cost and expense, make all
    improvements, alteration, modifications, additions and attachments to the
    Equipment required or recommended by any Federal, State, or local
    governmental body or agency. Lessee shall not make any other alterations,
    additions, deletions or improvements to the Equipment without the prior
    written consent of Lessor. All such changes shall immediately be and become
    part of the Equipment and Collateral under this Lease.

12. LOSS/DAMAGE. Lessee shall assume and bear risk of loss and damage to the
    Equipment and all component parts thereof from any and every cause
    whatsoever, whether or not covered by insurance. No loss or damage to the
    Equipment or any component part thereof shall impair any obligation of
    Lessee under this Lease, which shall continue in full force and effect. In
    the event of any loss and/or damage of any kind to the Equipment, or any
    items(s) of Equipment, Lessee, at the option of Lessor, shall (a) place the
    same in first class condition and repair, or (b) replace the same with like
    Equipment in first class condition and repair.

13. INSURANCE. Lessee agrees to keep the Equipment insured to protect all
    interest of Lessor against all risks of loss and/or damage from any cause
    whatsoever until the earlier of (a) delivery by Lessee of possession of the
    Equipment to Lessor, or (b) payment by Lessee of all amounts due under the
    Lease. Lessee shall keep the Equipment insured in such amounts, in such
    forms and with such insurers satisfactory to Lessor, including, but not
    limited to, fire and extended coverage insurance, explosion and public
    liability and property damage liability. Said insurance shall cover the
    interest of both the Lessor and Lessee in the Equipment, and shall name
    Lessor as loss payee. The proceeds of said loss or damage insurance shall be
    payable to Lessor, but Lessor shall remit all such insurance proceeds to
    Lessee at such time as Lessee either (i) provides Lessor satisfactory proof
    that the damage has been repaired and the Equipment has been restored to
    good working order and condition, or (ii) the Equipment has been replaced
    with like Equipment in first class condition and repair. All such insurance
    shall provide for thirty (30) days prior written notice to Lessor of
    cancellation, restriction or reduction of coverage. Certificates,
    endorsements and copies of all policies of insurance shall be delivered to
    Lessor upon request.

14. NET LEASE/INDEMNITY/TAXES. This is a net lease, and Lessee hereby
    indemnifies Lessor against and holds Lessor harmless (on a net after tax
    basis) from any and all claims, (including tax claims) actions, suits,
    proceedings, costs, expenses, damages and liabilities, including reasonable
    attorney fees, arising out of or connected with the Equipment or the
    delivery, use, ownership, lesae or possession thereof, or arising out of any
    failure by Leasee to perform or comply with any of the terms and conditions
    of this Lease. Lessee should be responsible for the timely payment and
    discharge of all license and registration fees, personal property taxes and
    other taxes now or hereafter imposed by any federal, state, or local
    government upon the Equipment whether the same be assessed to Lessor or
    Lessee. The indemnities contained in this paragraph shall continue in full
    force and effect notwithstanding the termination of this Lease, whether by
    expiration of time, by operation of law, or otherwise.

15. SURRENDER/HOLDOVER. Upon default, or upon earlier termination of the Lease,
    Lessee at its expense, and with all shipping and handling costs prepaid,
    shall return the Equipment in first class condition and repair, ordinary
    wear and tear excepted, by delivering said Equipment to Lessor's corporate
    office or to such other place as Lessor may specify. Lessee shall, upon
    demand by Lessor, pay to Lessor all amounts expended by Lessor to bring the
    Equipment to first class condition and repair, ordinary wear and tear
    excepted. This obligation of Lessee shall survive the expiration or earlier
    termination of this Lease. In the event of holdover after expiration of the
    Basic Term, Lessee shall also pay to Lessor an amount equal to the daily
    equivalent of the Basic Rent until the Equipment is returned to Lessor;
    provided that nothing herein shall be deemed to prevent Lessor, by written
    release, from abandoning its interest in the Equipment in place to Lessee
    without liability therefor.

16. NOTICES. All notices shall be in writing and sent by first class mail and
    shall be deemed to have been given when deposited in the U.S. mail with
    postage prepaid and properly addressed. The addresses of the parties shall
    be as indicated on this Lease or changed in accordance herewith.

17. LESSOR'S PERFORMANCE OPTION. Should Lessee fail to make any payment or to do
    any act as provided by this Lease, then Lessor shall have the right (but not
    the obligation), with or without notice to Lessee of its intention to do so
    and without releasing Lessee from any obligation hereunder to make or to do
    the same, to pay, purchase, contest or compromise any insurance premium,
    encumbrance, charge, tax, lien or other sum which may affect the value of
    the Equipment and/or Collateral. All sums so incurred or expended by Lessor
    shall be due and payable by Lessee to Lessor within ten (10) days of notice
    thereof.

18. EVENTS OF DEFAULT. The occurrence of any of the following events shall, at
    the option of Lessor, constitute an event of default under this Lease and/or
    any Schedule: (a) the nonpayment by Lessee of any Basic Rent when due; or
    the nonpayment by Lessee of any other sum required hereunder which
    nonpayment continues for a period of ten (10) days following written notice
    thereof from Lessor; (b) the failure of Lessee to perform or observe any
    other term, convenant or condition of this Lease, any Schedule or any other
    document, agreement or instrument executed pursuant hereto or in connection
    herewith which is not cured within ten (10) days after written notice
    thereof from Lessor; (c) Lessee ceases doing business as a going concern or
    commences or has commenced against it any dissolution or liquidation
    proceeding, is insolvent, has a trustee, receiver or custodian appointed for
    it or for a substantial part of its assets, makes an assignment for the
    benefit of creditors, is generally not paying its debts as they become due,
    commences or has commenced against it, or suffers, approves, acquiesces in
    or consents to a bankruptcy proceeding or any proceeding seeking relief by
    way of reorganization, arrangement or composition under any present or
    future statute, law or regulation; (d) Lessee attempts, incurs or suffers a
    major rearrangement of its debt, (e) Lessee defaults or otherwise has
    accelerated against in any material obligation under any credit agreement,
    loan agreement, conditional sales contract, lease, indenture, debenture or
    other instrument, or Lessee defaults under any agreement or instrument now
    existing or hereafter made with Lessor or with any Lessor's affiliates; (f)
    the breach or repudiation by any party thereto of any guaranty,
    subordination agreement or other agreement or instrument running in favor or
    Lessor obtained in connection with this Lease, or such party's dissolution,
    death, insolvency, or bankruptcy.

19. REMEDIES. Should any event of default occur, Lessor may, with or without,
    notice or demand upon Lessee, pursue and enforce, successively and/or
    concurrently, any one or more of the following remedies: (a) pursue its
    remedies under Section 18: (b) WITH OR WITHOUT RETAKING POSSESSION OF THE
    EQUIPMENT, with or without judicial process and without liability to Lessee
    therefor which is hereby expressly waived, (1) terminate the Basic Term as
    to the equipment, (2) accelerate all Basic Rents and cause the then worth
    thereof to become immediately due and payable; (3) from time to time recover
    from Lessee any accrued and unpaid Basic Rents and other amount owing under
    the terms hereof, (4) sell the Equipment at public or private sale, and
    recover from Lessee the difference, if any, by which the net proceeds of
    sale shall be less than (i) the Lessor's then applicable net investment in
    the Equipment and the Lease, plus (ii) the then worth to Lessor of its
    anticipated remaining loss of bargain, (5) lease or rent the Equipment to a
    third party for the account of Lessee and recover from Lessee when becoming
    due any deficiency between the Basic Rents provided herein, and those
    amounts received and receivable from such third party over the remaining
    Basic Term; (c) pursue any other remedy Lessor may otherwise have hereunder,
    at law, in equity (including specific performance) or under any statute any
    recover such other actual damages as may be incurred by Lessor. Lessor's
    pursuit and enforcement of any one or more remedy shall not be deemed an
    election of, or waiver by, Lessor of any other or further remedy, provided,
    however, Lessor shall not be entitled to duplicate relief or recovery with
    respect to any specific element of Lessor's damages. In addition, Lessor
    shall attempt in good faith to mitigate its damages, but Lessor shall not be
    obligated to sell or lease the Equipment, but in the event of any such sale,
    Lessor and its affiliates may bid upon and purchase the Equipment. Any sale
    or lease may be held at such place or places as are selected by Lessor, with
    or without having the Equipment present. Lessee agrees, at Lessor's option,
    to permit Lessor to lease the Equipment in place without charge or liability
    to Lessor, and to permit Lessor to conduct a sale or lease therefrom, and in
    furtherance thereof, to permit appraisers, offerees and auctioneers
    reasonable and timely access to view, inspect, sell, purchase and remove the
    Equipment. Any such sale or lease may be at wholesale or retail, in bulk or
    in parcels. He further agrees, upon the sale or lease of the Equipment
    occasioned by Lessee's default hereunder, to pay Lessor an amount equal to
    any and all disassembly, transportation and reinstallation costs and
    expenses incurred by any party with respect to redeployment of the
    Equipment. Lessor may accept past due payments without modifying the terms
    of the Lease and without waiving any further rights of Lessor.

20. INTEREST/SERVICE CHARGE. Any amounts required to be paid by Lessee pursuant
    to the Lease, and not paid when due shall bear interest each day at the
    lessor of (18%) eighteen percent per annum or the highest legal contract
    rate from the date when such amount was due until paid. Lessee shall also
    pay, as indemnity, but not as interest, an additional service charge equal
    to the greater of $10.00 or an amount equal to 5% of any such unpaid
    amounts. Nothing herein shall be deemed to require the assessment or payment
    of any amounts not otherwise legally recoverable by Lessor.

21. COSTS/ATTORNEY'S FEES: In the event of any actions or suits by reason of
    Lessee's breach of this Lease, or in connection with the enforcement of any
    right or remedy hereunder, Lessor employs the services of any attorney to
    enforce, construe or defend any of the terms of this Lease. Lessee, in
    addition to all other sums which Lessee may be called upon to pay under the
    provisions of this Lease, will pay and/or reimburse Lessor for costs of
    collection, other identifiable or out-of-pocket costs and expenses and any
    attorney's fees on account thereof reasonably incurred by Lessor.

22. APPLICABLE LAW. This Lease, and all ancillary document issued or executed
    pursuant hereto and the rights and obligations of the parties hereunder and
    thereunder shall be governed by the laws of the State of Minnesota. In the
    event any provision hereof shall be deemed invalid or unenforceable, the
    remaining provisions hereof shall remain in full force and effect. Lessee
    hereby expressly and irrevocably agrees that Lessor may bring any action or
    claim to enforce the provisions of this Lease in the State of Minnesota and
    Lessee hereby irrevocably consents to personal jurisdiction in the
    appropriate State of Minnesota or Federal Court therein. Lessee hereby
    further irrevocably consents to service of process, in accordance with the
    provisions of the laws of the State of Minnesota. Nothing herein shall be
    deemed to preclude or prevent Lessor from bringing any action or claim to
    enforce the provisions of this Lease in any other appropriate place or
    forum.

23. WAIVER. No failure nor delay on the part of Lessor in the exercise of any
    power, right or privilege hereunder, or to object to the mode of any
    tendered performance shall operate as a waiver of the terms hereof, nor
    shall any single or partial waiver be construed to preclude future exercise
    by Lessor of its rights, powers and privileges.

24. MISCELLANEOUS. Time is of the essence of this Lease and each and all of its
    provisions. Section headings are used for convenience only and shall not
    otherwise affect the provisions of this Lease. THIS LEASE MAY ONLY BE
    AMENDED OR ALTERED BY AN INSTRUMENT IN WRITING SIGNED BY AN AUTHORIZED
    OFFICER OF LESSOR. ALL REPRESENTATIONS, AGREEMENTS, INDEMNITIES AND
    WARRANTIES OF LESSEE MADE HEREIN AND REMEDIES OF LESSOR SHALL SURVIVE
    TERMINATION OF THIS LEASE AND ANY SCHEDULE.
