                            THIRD AMENDMENT TO LEASE

         THIS THIRD AMENDMENT TO LEASE ("Third Amendment") is made as of January
22, 2002, by and between AMERICAN OSTEOPATHIC ASSOCIATION, an Illinois
not-for-profit corporation ("Landlord") and BROADVIEW MEDIA, INC., formerly
known as NORTHWEST TELEPRODUCTIONS/CHICAGO, INC., a Minnesota corporations
("Tenant").

RECITALS:

         A.       Landlord and Tenant executed that certain Lease dated January
31, 1994, as amended by that certain First Amendment to Lease dated July, 1996,
and that certain Second Amendment to Lease dated April 2, 1998 (the "Lease") for
7, 510 square feet of space (the "Current Premises") located on the third floor
of that certain office building situated in Chicago, Illinois, and commonly
known as 142 East Ontario Street (the "Building").

         B.       Landlord and Tenant wish to amend the Lease to delete the
third floor from the lease, substitute the twelfth floor and extend the Term.

         NOW, THERFORE, in consideration of the mutual promises contained herein
         and for other good and valuable consideration, the receipt and
         sufficiency of which are hereby acknowledged, Landlord and Tenant agree
         to amend the lease as follows.

         1.       INCORPORATION OF RECITAL. The foregoing Recitals and all
exhibits to this Third Amendment, by this reference, are incorporated herein as
if the same had been set forth in this Third Amendment.

         2.       SECOND SUBSTITUTE PREMISES. Landlord and Tenant have agreed
that in place of the Current Premises Tenant will lease the 7,510 rentable
square feet on the twelfth floor (the "Second Substitute Premises") as shown on
Exhibit A attached hereto. Landlord will deliver possession of the Second
Substitute Premises to Tenant in order for Tenant to perform improvements in the
Second Substitute Premises. During the period commencing with the delivery of
the Second Substitute Premises and ending on the Second Substitute Premises
Commencement Date, the term "Premises" shall mean the Current Premises and the
Second Substitute Premises unless the context requires otherwise (for example,
Tenant will be required to insure its operations in both spaces but will be
required to pay Rent during this period on the equivalent of only one space.) As
of the earlier of the date Tenant opens for business in the Second Substitute
Premises or June 1, 2002 (the "Second Substitute Premises Commencement Date),
Tenants rights and obligations with respect to the third floor will cease in the
same manner as if that date had been originally fixed in the Lease for the
expiration of the Term with respect to the third floor. (Thus, Tenant shall only
be required to pay Rent on both the Current Premises and the Second Substitute
Premises if Tenant holds over in the Current Premises beyond the Second
Substitute Premises Commencement Date). Tenant agrees to vacate the third floor
and deliver possession thereof to Landlord by the Second Substitute Premises
Commencement Date. In addition, Tenant shall remove the items listed on Exhibit
F and the audio room windows and doors from the Current Premises by the Second
Substitute Premises Commencement Date, such removal to be in compliance with
Tenant's obligations under article 16. Tenant shall pay to Landlord all Rent and
other charges as specified in the Lease as amended hereby through the Second
Substitute Premises Commencement Date, for the third floor in accordance with
the terms of the Lease as if that date had been originally fixed in the Lease
for the expiration of the Term with respect to the third floor. Therefore, as of
the Second Substitute Premises Commencement Date, and with respect to periods
thereafter, the term "Premises" shall mean the Second Substitute Premises unless
the context requires otherwise. Notwithstanding the above, Landlord


                                       1
<PAGE>
acknowledges that the items listed on Exhibit F and the audio room windows and
doors are the property of Tenant and may be reinstalled in the Second Substitute
Premises, and, if Tenant does so, such items may be removed by Tenant at the
expiration of the Extension Term (as hereinafter defined), subject to Tenant's
obligations under Article 16.

         3.       CONDITION OF SECOND SUBSTITUTE PREMISES. Tenant acknowledges
and agrees that the Second Substitute Premises are being leased in their "AS-IS"
condition without representation or warranty by Landlord or any other party, and
Landlord has no obligation to make any alterations, improvement or repairs to
the Premises or to provide Tenant with and allowance in connection therewith
Premises except that Landlord will make available an allowance of $25.00 per
square foot in the Second Substitute Premises to improve the Second Substitute
Premises (the "Allowance"). All work in the Second Substitute Premises shall be
done in accordance with the terms of the Lease with respect to the construction
of alterations, including the requirement of Landlord's prior approval of plans.
The Allowance shall be disbursed to Tenant's contractor upon receipt of final
lien waivers and other evidence of lien-free completion in accordance with
approval plans as Landlord shall reasonably determine. A portion of the
Allowance not to exceed $3.00 per square foot in the Second Substitute Premises
may be used to reimburse Tenant for moving costs and will be disbursed to Tenant
upon receipt of final paid bills. In addition, Tenant may request that Landlord
increase the Allowance up to an additional $6.00 per square foot in the Second
Substitute Premises. If Tenant so requests, the amount so advanced by Landlord
in excess of the Allowance (the "additional Improvement Allowance") shall be
recovered by Landlord by calculating the monthly amount necessary to amortize
the Additional Improvement Allowance over the balance of the Extension Term
commencing June 1, 2002 [i.e., ten (10) years] with interest at ten percent
(10%) per annum and such amount shall be added to and become part of the Base
Rent for the Second Substitute Premises. Promptly following the Commencement
Date, Tenant and Landlord will execute and deliver an amendment to the Lease
setting forth the adjusted Base Rent for the Premises.

         4.       EXTENSION OF TERM. The Term shall be extended from the current
Termination Date of April 30, 2002, until May 31, 2012 (the "Extension Term").

         5.       BASE RENT.  Base Rent with respect to the Second Substitute
Premises for the Extension Term shall be payable by Tenant to Landlord in
monthly installments, in advance, for the time periods and in the amounts set
forth below:

The Base Rent may be increased to reflect Tenant's election to use the
Additional Improvement Allowance as provided in paragraph 3 above. In addition,
Tenant shall pay Rent Adjustments and Rent Adjustments Deposits pursuant to the
Lease.

         6.       PROPORTIONATE SHARE. Tenant's Proportionate Expense Share
shall remain 5.6627% and Tenant's Proportionate Tax Share shall remain 7.8993%,
subject to adjustment as provided in the Lease, except that from and after the
Second Substitute Premises Commencement Date, the Expense Stop shall be actual
2002 Operating Expenses (computed on a rentable square foot basis) and the Tax
Shop shall be actual 2002 taxes (computed on a non-exempt square foot basis)

         7.       SECURITY DEPOSIT. Concurrently with the execution of this
Third Amendment, Tenant shall deposit with Landlord the sum of $31,291.66 as the
Security Deposit. On June 1 of each year during the Term, Tenant shall deposit
with Landlord the amount needed to increase the Security Deposit to the product
of two (2) times the sum of (a) the monthly Installment of Base Rent plus for
the ensuing month (b) the estimated Expense Adjustment Amount for the ensuing
month, and (c) the estimated Tax Adjustment Amount for the ensuing month.
Article 25 if the Lease is hereby deleted in its entirety and replaced and
replaced with the following:

                         "ARTICLE 25 - SECURITY DEPOSIT

                  Tenant has deposited with Landlord the Security Deposit as
         security for the prompt, full and faithful performance by Tenant of
         each and every provision of this Lease and of all obligations of Tenant
         hereunder.

                  A.      USE. If Tenant fails to perform any of its obligations
         hereunder, Landlord may use, apply or retain the whole or any part of
         the Security Deposit for the payment of (i) and Rent or other sums of
         money which Tenant may not have paid when due. (ii) any sum expended by
         Landlord on Tenant's behalf in accordance with the provisions of the
         Lease, ad/or (iii) any sum which Landlord may expend or be required to
         expend by reason of Tenants default, including, without limitation, any
         damage or deficiency in or from the reletting of the Premises as
         provided in Article 22. The use, thereof, by Landlord shall not prevent
         Landlord from exercising any other right or remedy provided by this
         Lease or by law (it being intended that Landlord shall not first be
         required to proceed against the Security Deposit) and shall not operate
         as a limitation on any recovery to which Landlord may otherwise be
         entitled. If any portion of the Security Deposit is used, applied or
         retained by Landlord for the purposes set forth above, Tenant agrees,
         within ten (10) days after the written demand therefore made by
         Landlord, to deposit cash with the Landlord in an amount sufficient to
         restore the Security Deposit to its original amount.

                  B.      RETURN. If Tenant shall fully and faithfully comply
         with all of the provisions of this Lease, the Security Deposit, or any
         balance thereof, shall be returned to Tenant without interest after the
         expiration of the Term or upon any later date after which Tenant has
         vacated the Premises. In the absence of evidence satisfactory to
         Landlord if any permitted assignment of the right to receive the
         Security Deposit, or of the remaining balance thereof, Landlord may
         return the same to the original Tenant, regardless of one or more of
         the assignments of Tenants interest in this Lease or the Security
         Deposit. In such event, upon the return of the Security Deposit, or the
         remaining balance thereof to the original Tenant, Landlord shall be
         completely relieved.

                  C.      TRANSFER. Tenant acknowledges that Landlord has the
         right to transfer or mortgage its interest in the Land and the Building
         and in this Lease and Tenant agrees that in the event of any such
         transfer or mortgage, Landlord shall have the right to transfer or
         assign the



                                       3
<PAGE>
         Security Deposit to such transferee or mortgagee. Upon such transfer or
         assignment, Landlord shall thereby be released by Tenant from all
         liability or obligation for the return of such Security Deposit and
         Tenant shall look solely to such transferee or mortgagee for the return
         of the Security Deposit."

         8.       CHILLED WATER. Tenant has requested that Landlord supply
approximately fifteen (15) ton of chilled water to the supplement air
conditioning units which Tenant wishes to install to service the Second
Substitute Premises. A riser with a vertical chilled water line is available for
tap in on the twelfth floor. Connections to the chiller water rise shall be made
pursuant to plans approved by Landlord and by a contractor reasonably acceptable
to Landlord at Tenant's expense. Tenant agrees to pay monthly with the each
Monthly Installment of Base Rent a fee equal to Five Dollars ($5.00) per ton of
chilled water and Landlord will supply for Tenant's use approximately use
approximately fifteen (15) ton of chilled water. In addition, Tenant shall
comply with Landlord's rules and regulations with respect to the use of such
water chiller. Tenant acknowledges that Landlord shall not be liable if the
water chiller does not function as designed and that the provisions of Paragraph
6(D) of the Lease (Interruptions of Service) shall apply to the provision of
chilled water service.

         9.       RIDER 3. Rider 3 of the Lease is hereby deleted in its
entirety and replaced with Rider 3 attached hereto.

         10.      RIDER 7. Rider 7 attached hereto is hereby added to the Lease.

         11.      RIDER 8. Rider 7 attached hereto is hereby added to the Lease.

         12.      BROKERS. Landlord and Tenant each represent and warrant to the
other that it has not dealt with any brokers in connection with this Third
Amendment other than Julien J. Studley, Inc. and The John Black Company, whose
commission shall be paid by Landlord. Landlord and Tenant each agrees to defend,
indemnify and hold the other harmless from and against any and all claims by any
other broker for fees, commissions or other compensation to the extent such
broker alleges to have been retained by the indemnifying party in connection
with the execution of this Third Amendment. The provisions of this Section 13
shall survive the expiration or termination of the Lease.

         13.      SEVERABILITY. If any provision of this Third Amendment or the
application thereof to any person or circumstance is or shall be deemed illegal,
invalid or unenforceable, the remaining provisions hereof shall remain in full
force and effect and this Third Amendment shall be interpreted as if such
illegal, invalid or unenforceable provision did not exist herein.

         14.      MISCELLANEOUS.

         (a)      Except to the extent stated or modified herein, all other term
and conditions of the Lease shall remain and continue in full force and effect
as originally written and shall apply to this Third Amendment as if set forth in
their entirety herein.

         (b)      Capitalized terms used but not defined herein shall have the
meanings ascribed thereto in the Lease.

         (c)      Time is of the essence of this Third Amendment and each
provision hereof.

                           RIDER 3 - EXTENSION OPTION

         Subject to the conditions set forth in paragraph 3 below, the Term of
this Lease may be extended, at the option of Tenant, for one addition of five
(5) (the "Renewal Term"). The Renewal Term shall be upon the same terms,
covenants and conditions contained in this Lease, excluding the provisions
modified hereby, and any reference in the Lease to the "Term" of the Lease shall
be deemed to include the Renewal Term and apply thereto, unless it is expressly
provided otherwise. Tenant shall have no extension option beyond the aforesaid
option. Any termination of this Lease during the Term of this Lease shall
terminate all rights under this Rider 3.

         1.       The Base Rent during the Renewal Term for any space then
                  constituting a portion of the Premises shall be at a rate
                  equal to the then prevailing market rate (including (i) market
                  concessions, if any, such as rent abatement, and (ii) Tenant;s
                  obligation to pay its Proportionate Share of Opening Expenses
                  and Taxes) for fuly credit worthy tenants for comparably
                  built-out space in the Building and other first class office
                  buildings in the vicinity of the Building as reasonably
                  determined by Landlord.

         2.       Such option to extend shall be exercised by Tenant delivering
                  an initial nonbonding written notice to Landlord not less than
                  twelve (12) full calendar months prior to the expiration of
                  the initial Term of this Lease. Thereafter, Landlord shall
                  calculate the prevailing market rate of the Premises, which
                  calculation shall reflect the market rate that would be
                  payable per annum for a term commencing on the first day of
                  the Renewal Term. Landlord shall deliver such calculation to
                  Tenant within thirty (30) days after Landlord receives
                  Tenant's initial non-binding written notice. Within five (5)
                  days after Landlord advises Tenant of its determination of the
                  prevailing market rate, Landlord and Tenant shall negotiate in
                  good faith to reach agreement on the prevailing market rate.

                  If Landlord and Tenant are unable to reach agreement on the
                  prevailing market rate within twenty-one (21) days after the
                  date negotiations commenced, then within seven (7) days
                  thereafter Landlord and Tenant shall each simultaneously
                  submit to the other in writing its good faith estimate of the
                  prevailing market rate, which estimate shall be a reduction to
                  writing of its final determination of the prevailing market
                  rate in the preceding negotiations and not a new position. If
                  the process of reducing the parties positions to writing does
                  not result in an agreement, the parties shall select, as an
                  arbitrator, a mutually acceptable independent MAI appraiser or
                  broker with experience in real estate activities, including at
                  least five (5) years experience in appraising or leasing
                  office space in the north Michigan Avenue area (a "Qualified
                  Appraiser"). If the parties cannot agree on a Qualified
                  Appraiser, then within ten (10) days thereafter the two
                  appointed Qualified Appraisers shall select a third Qualified
                  Appraiser and the third Qualified Appraiser shall be the
                  arbitrator and shall determine the prevailing market rate. If
                  one party shall fail to make such appointment within said
                  second seven (7) day period, then the Qualified Appraiser
                  chosen by the other party shall be the sole arbitrator. As
                  soon as practicable after his selection but in any case within
                  twenty-one (21) days, the arbitrator shall select one of the
                  two estimates of prevailing market rate submitted by Landlord
                  and Tenant, which shall be the one that is closer to the
                  prevailing market rate. The decision of the arbitrator as to
                  the prevailing market rate shall be submitted in writing to,
                  and be final and binding on, Landlord and Tenant. If the
                  arbitrator believes that expert advice would materially assist
                  him, he may retain one or more qualified persons, including
                  but not limited to, legal counsel, brokers, architects or
                  engineers, to provide such expert advice. The party whose
                  estimate is not chosen by the arbitrator shall pay the costs
                  of the arbitrator and any experts retained by the arbitrator.
                  Any fees of


                                       7
<PAGE>
                  any counsel or expert engaged directly by Landlord or Tenant
                  shall, at option, give Landlord final binding written notice
                  of intent to exercise its option to extend no later than ten
                  (10) months prior to the expiration of the initial term.

         3.       Tenant's right to exercise its option to extend this Lease and
                  to extend this Lease pursuant to this Rider 3, is subject to
                  the following conditions: (i) that on the date that Tenant
                  delivers its initial non-binding written notice of its
                  election to exercise its option to extend, Tenant is not in
                  default under any of the term, covenants or conditions of the
                  Lease (after the expiration of any applicable notice and cure
                  periods) (ii) that on the date that Tenant delivers its final
                  binding written notice of its election to exercise its option
                  to extend, Tenant is not in default under any of the terms,
                  covenants, or conditions of the Lease without regard to any
                  notice or cure periods, and (iii) that on the date that
                  Tenant's extension option commences, Tenant is not in default
                  under any of the terms, covenants or conditions of the Lease,
                  after the expiration of any applicable notice or cure periods.

         4.       If Tenant fails to give its initial non-binding written notice
                  of intent or its final binding written notice of intent to
                  exercise its option to extend when due as provided herein,
                  Tenant will be deemed to have waived the option to extend
                  provided by this Rider 3 for all purposes.

floor of the Building (collectively, the "ROFR Space"), which shall be exercised
in accordance with the procedures set forth below.

         1.       Each and every time after June1, 2002, Landlord proposes to
                  lease RPFR Space or any portion thereof to a third party,
                  Landlord shall give written notice thereof to Tenant (the
                  "Landlord's ROFR Notice") identifying that portion of the ROFR
                  Space that is to be leased (the "Subject's ROFR Space") along
                  with a copy of the proposed lease terms (except that Landlord
                  may eliminate references to the name and address of the
                  proposed tenant). Within ten (10) business days after receipt
                  of Landlord's ROFR Notice, Tenant shall deliver to Landlord
                  binding written notice of intent to lease the Subject ROFR
                  Space. If Tenant fails to deliver its binding notice within
                  such 10-day period, Tenant shall be deemed to have refused to
                  exercise its right of first refusal. After Tenant refuses of
                  is deemed to have refused to exercise its rights under this
                  Rider 7, Tenant shall have no further rights to the Subject
                  ROFR Space and such lease expires or is otherwise terminated
                  during the Term of the Lease, then Landlord shall not enter
                  into a new lease for the Subject ROFR Space without first
                  offering such space to Tenant pursuant to this provision.

                  If Tenant exercises its right of first refusal with respect to
                  the Subject ROFR Space within the time period allowed, such
                  space shall be added to the Premises for the lesser of the
                  term set forth in the Landlord's ROFR Notice or the remaining
                  Term of the Lease (including the Renewal Term, if any) on all
                  the terms, covenants and conditions specified in the
                  Landlord's ROFR Notice. Tenant's obligations to pay Base Rent
                  and Additional Rent with respect to such ROFR Space shall
                  begin on the date such ROFR Space is added to the Premises.
                  Any ROFR Space added to the Premises pursuant to this Rider 7
                  shall become a part of the Premises for all purposes of this
                  Lease, and any references in this Lease to the term "Premises"
                  shall be deemed to refer to and included such portion of the
                  ROFR Space, except as expressly provided otherwise in this
                  Lease.

         2.       Tenant's right to exercise its right of first refusal with
                  respect to the Subject ROFR Space pursuant to this Rider 7 is
                  subject to the following condition: that in the date that
                  Tenant delivers its binding written notice of its election to
                  exercise it right of first refusal, Tenant is not in default
                  under any of the terms, covenants or conditions for the Lease
                  without regard to notice or cure periods. Promptly after
                  Tenant's exercise of its right of first refusal pursuant to
                  this Rider 7, Landlord shall prepare an amendment to the Lease
                  to reflect changes in the size of the Premises, Base Rent,
                  Tenant's Proportionate Share and any other appropriate terms
                  and provision of the Lease, due to the addition of the Subject
                  ROFR Space. Tenant shall execute and return such an amendment
                  to the Lease within thirty (30) days after its submission to
                  Tenant. Landlord and Tenant shall negotiate in good faith
                  during the thirty (30) days after submission of the draft
                  amendment to Tenant to reach agreement on any issue raised
                  concerning the amendment.
