</TABLE>

         1. LEASE: Subject to the terms of this Agreement, from the Closing Date

request, certain telecommunications network and data transmission equipment and
related products and services ("Equipment") described in any Equipment Schedule
("Schedule") executed from time to time by Lessor and Lessee that makes
reference to this Master Lease Agreement ("Agreement"), up to a maximum
aggregate purchase price of $25,000,000. This Agreement shall be incorporated
into each Schedule. When computer programs and related documentation are
furnished with the Equipment, and a non-exclusive license and/or sublicense
(collectively, "Software") is granted to Lessee in an agreement ("Supplier
Agreement") with the Suppliers identified on a Schedule, Lessor, to the extent
permitted, grants Lessee a similar non-exclusive sublicense to use the Software
only in conjunction with the Equipment for so long as the Equipment is leased
hereunder. The Equipment and Software include, but are not limited to, all
additions, attachments and accessions thereto and replacements thereof
(collectively, "System"). Any reference to "Lease" shall mean with respect to
each System, this Agreement, a Schedule, an Acceptance Certificate, any riders,
amendments and addenda thereto including the Financial Covenant and Reporting
Requirements Annex and the Definitions Annex, both of which are attached hereto
and made a part hereof, and any other documents as may from time to time be made
a part thereof. Terms not defined herein shall have the meanings set out in any
Schedule.

the Schedule, and shall exclude all other costs, including sales or

<PAGE>   2

other taxes included in the Supplier Agreement as part of the purchase price,
unless approved by Lessor. The Price may be amended as set forth in a Lease. All
Systems must be obtained from the Supplier or provided through its approved OEM
arrangement, including its subsidiaries and affiliates, and other Suppliers
approved by Lessor. The amount of the Price attributable to freight,
installation, maintenance and other services subject to a Lease shall not exceed
an amount equal to twenty percent (20%) of the Price relative to the Lease.

Lessee shall pay all reasonable fees, charges and expenses of Lessor (including,
without limitation, the reasonable fees, charges and expenses of Lessor's
counsel) arising in connection with the structuring of this Agreement and all
Leases contemplated herein and in connection with the negotiation, drafting,
preparation, execution and/or delivery of this Agreement and any Schedules and
all related documents regardless of the commencement of any Lease; provided
however, if this Agreement or any Lease is not consummated by Lessor other than
as a result of Lessee's failure to satisfy all conditions precedent, Lessor
shall bear the associated costs. Lessee shall also pay all closing costs
including reasonable legal fees and charges, as well as stamp or other recording
costs and related taxes or charges, filing fees, costs and expenses of Lessor.

         the Financial Covenants and Reporting Requirements Annex (and attaching
         to such certificate evidence of such compliance). If changes in
         circumstances arising after the date of this Agreement prevent Lessee
         from so certifying, Lessee shall attach to such certificate an updated
         Disclosure Annex identifying and explaining such changes, and Lessor
         shall have no obligation to purchase and lease the Equipment or
         sublicense the Software unless such changes are acceptable to Lessor in
         its sole discretion.

                  (c) Prior to entry into a proposed Schedule in respect of

<PAGE>   5

                  (d) Lessor, in its reasonable opinion shall determine that
         there has not been a material adverse change in the Lessee's business,
         operations or financial condition since the date specified in Section
         3(d).

                  (e) No Event of Default or no event which, with the giving of

         shall have occurred and be continuing under any Lease.

                  (f) Lessor shall have received an Opinion of Counsel from
         Lessee's counsel in each state where the Installation Sites or staging
         areas for the Lease are located as to the perfection of Lessor's
         security in the Systems to be located in such state. If applicable,
         Lessor shall have received an Opinion of Counsel from Lessee's counsel
         in the state where in which Lessee was organized as to the perfection

         certificates, secretary certificates and all other documents,
         instruments, certifications, reports, and proceedings which Lessor
         shall reasonably request.

All of the foregoing shall in form and substance be reasonably satisfactory to
Lessor.

         5. ASSIGNMENTS BY LESSEE: Upon Lessee's execution of a Schedule
relative to a Lease, Lessee assigns to Lessor its rights to receive title to the
Equipment and any non-exclusive sublicense to use the Software described in the
Supplier Agreement as of the day the System is delivered to the Installation
Site set forth in the applicable Schedule but no other right or any warranty
thereunder. In consideration of such an assignment and subject to the terms and
conditions herein, Lessor agrees to pay to the Supplier the Price for the System
set forth in the Schedule, but not to perform any other obligation under the
Supplier Agreement. Unless Lessee exercises its Purchase Option as set forth in
the applicable Schedule, Lessee hereby assigns to Lessor all of Lessee's
then-remaining rights pursuant to the applicable Supplier Agreement effective
upon the termination or expiration of the Term (as set forth in the applicable
Schedule) for any reason.

<PAGE>   6

         6. TERM, RENEWAL AND EXTENSIONS: If all other conditions precedent to a
Lease have been met, the Term for the System described on each Schedule shall
commence on the date Lessee accepts the System as set forth in an Acceptance
Certificate ("Commencement Date"), and continue for thirty-six (36) whole months
("Initial Term"), the first such full month commencing on the first day of the
month following the Commencement Date (or commencing on the Commencement Date if
such date is the first day of the month). On the expiration date of the Initial
Term, the Lease shall be automatically renewed for a six-month period ("Renewal
Term") unless, by giving written notice to Lessor three (3) months prior to the
expiration date ("Notification Date"), the Lessee elects to terminate the Lease
or Lessor and Lessee agree to a specific extension of the Lease. At least
fifteen (15) days but not more than thirty (30) days prior to the Notification
Date, Lessor shall give Lessee written notice reminding Lessee of the existence
of the preceding Lease provision. After the Renewal Term the Lease shall be
automatically extended on a month-to-month basis until either party gives the
other not less than thirty (30) days prior written notice of its intention to
terminate the Lease. Any renewals and extensions shall be on the same terms and
conditions as during the Initial Term and, for the avoidance of doubt, the Rent
payable shall be that specified with respect to the final month of the Initial
Term.

         7. RENT, PAYMENT, APPLICATION OF FEE, AND LATE CHARGES: The Rent set
forth in a Schedule is determined by multiplying the Lease Rate Factor set forth
in the Schedule by the Price set forth in the Schedule. Until each Lease
commences the Lease Rate Factor shall be increased or decreased based upon
changes from June 29, 2000 of 6.32% until the Commencement Date for each Lease
in the Treasury Yield. Such Treasury Yield as of June 29, 2000, was 6.32%. For
every 25 basis points of increase or decrease (rounded downward to the nearest
whole 25 basis point increment or decrement) in the Treasury Yield, the Lease
Rate Factor shall be increased or decreased by an adjustment factor of
 .00013159, and the monthly Rent payment shall be adjusted accordingly. Rent may
be further adjusted pursuant to the terms of a Lease.

Lessee shall pay to Lessor all Rent during the Term of the Lease plus such
additional amounts as are due Lessor under the Lease. Rent shall be paid as
designated in the applicable Schedule in advance on the first day of each
Payment Period ("Rent Payment Date"). If the Commencement Date is not the first
day of a calendar month, Lessee shall pay to Lessor, on demand, interim Rent
prorated daily based on a 360-day year for each day from and including the
Commencement Date to and including the last day of such month or other Payment
Period.

If the Price to be paid to the Supplier is decreased as a result of a JCO" prior
to the commencement of a Lease, Lessee authorizes Lessor to adjust the Price and
the Rent using the same Lease Rate Factor. If the price charged by Supplier for
the System is increased as a result of a JCO, and such increase is within 10% of

<PAGE>   7

the Price and prior to the date set out in Section 4(a) hereto and Section 4(c)
would not by reason of any increase become applicable (unless evidence
satisfactory to Lessor is provided of Lessee's compliance therewith) and the
events described in Sections 4(d) and (e) hereof have not occurred, Lessee
authorizes Lessor to increase the Price to reflect the JCO and adjust the Rent
using the same Lease Rate Factor. If the Commencement Date occurs after the date
set out in Section 4(a), and Lessor waives the condition precedent that the
Commencement Date occur on or before such date, Lessor's then-current Lease Rate
Factor for similar transactions shall apply and Lessee authorizes Lessor to
adjust the Rent accordingly.

Whenever any payment of Rent or other amount is not made within ten (10) days
after the date when due, Lessee agrees to pay (as a fee to offset Lessor's
collection and administrative expenses), the greater of twenty-five dollars
($25.00) or five percent (5%) of each such overdue amount, but not exceeding the
lawful maximum, if any. All payments shall be payable to Lessor in U.S. dollars
at Lessor's address set forth in Section 11 of the Schedule or such other place
as Lessor directs in writing.

         8. DELIVERY: All transportation, delivery and installation costs
(unless included in the Price) are the sole responsibility of Lessee. As between
Lessee and Lessor, Lessee assumes all risk of loss and damage if the Supplier
fails to deliver or delays in the delivery of any System, or if any System is
unsatisfactory for any reason.

         9. NET LEASE: Lessee's obligations under each Lease are absolute,
unconditional and non-cancelable and shall not be subject to any delay,
reduction, setoff, defense, counterclaim or recoupment for any reason including
any failure of any System, or any misrepresentation of any supplier,
manufacturer, installer, vendor or distributor. Lessor is not responsible for
the delivery, installation, maintenance or operation of any System.

         10. SUPPLIER AND THIRD PARTY WARRANTIES: Except as set forth in Section
5, Supplier and other third-party warranties, if any, remain with Lessee. Lessee
agrees to pursue any warranty claim directly against such third party and shall
not pursue any such claim against Lessor. Lessee shall continue to pay Lessor
all amounts payable under any Lease under any and all circumstances.

         11. QUIET ENJOYMENT: Lessor shall not interfere with Lessee's quiet
enjoyment and use of the System during the Term if no Event of Default has
occurred and is continuing.

         12. TAXES AND FEES: Lessee shall promptly reimburse Lessor as
additional Rent, or shall pay directly, if so requested by Lessor, all license
and registration fees, sales, use, personal property taxes and all other taxes
and charges imposed by any federal, state, or local governmental or taxing
authority, relating

<PAGE>   8

to the purchase, ownership, leasing, or use of the System during the Term or the
Rent whether such taxes are assessed against Lessor or Lessee excluding,
however, all taxes computed upon the net income of Lessor.

         13. REPRESENTATION AND WARRANTIES: In addition to the other
representations and warranties contained in any Lease or other instrument,
agreement, report, certification or other document delivered by Lessee to
Lessor, Lessee hereby represents and warrants to Lessor as follows:

                  (a) Lessee is a duly organized corporation, validly existing
         and in good standing under the laws of the state of its formation.
         Lessee is duly qualified to do business and is in good standing in any
         jurisdiction in which it is conducting business.

                  (b) Lessee has all requisite right, power and authority to
         execute and deliver to perform its obligations under this Agreement,
         any Lease entered into pursuant to this Agreement and all related Lease
         documents (collectively, "Lease Documents"). Lessee's execution,
         delivery and performance of the Lease Documents have been duly and
         validly authorized by all necessary proceedings on the part of Lessee.

                  (c) All Lease Documents have been or will be duly and validly
         executed and delivered by Lessee and constitute, or when executed and
         delivered will constitute, the legal, valid and binding obligations of
         Lessee enforceable in accordance with the terms hereof and thereof,
         except as limited by bankruptcy, insolvency, reorganization or other
         similar laws or equitable principles.

                  (d) No authorization, consent, approval, license, exemption or
         other action by, and no legislation, qualification, declaration or
         filing with any Governmental Authority is or will be necessary in
         connection with the execution and delivery of the Lease Documents,
         consummation of the transactions herein contemplated, performance of or
         compliance by Lessee with the terms and conditions hereof or thereof or
         the legality, validity and enforceability hereof or thereof where the
         failure to obtain such consent could reasonably be expected to have a
         Material Adverse Effect.

                  (e) The execution and delivery of the Lease Documents, the
         consummation of the transactions contemplated herein and the
         performance of or compliance with the terms and conditions hereof or
         thereof by Lessee do not and will not (i) violate any applicable law
         including any rule, order, injunction, writ, decree or award; (ii)
         conflict with or result in the termination of or a material breach of
         or a default under any governing document of Lessee or any agreement or
         instrument to which Lessee is a party or by which Lessee or its
         properties is bound, including, without limitation, the Operating
         Agreements; or (iii) result in the creation or imposition of any lien
         upon any property (now owned or hereafter acquired) of Lessee except as
         otherwise contemplated by this Agreement and any Schedule hereto.

                  (f) Lessee has furnished to Lessor audited financial
         statements for the period ending December 31, 1999, and, if applicable,
         the related statements of income and retained earnings and cash flow
         for the fiscal period then ended. Such financial statements (including
         the notes thereto) present fairly the financial condition of Lessee and
         its Subsidiaries (if any) on a consolidated basis as of the end of such
         fiscal period and the results of its operations and the cash flow for
         the fiscal period then ended, all in conformity with GAAP applied on a
         basis consistent with that of the preceding fiscal period. The
         projections in the form of the business plan referred to in Section
         3(b) and pro forma financial statements delivered by Lessee to Lessor
         in July 2000 were prepared in good faith, based on reasonable
         assumptions. From May 3, 2000, the business of Lessee has been
         conducted only in the ordinary and usual course, consistent with past
         practices, and there has been no material adverse change in the
         business, operations or financial condition of Lessee, individually, or
         Lessee and its Subsidiaries taken as a whole.

                  (g) No event has occurred and is continuing and no condition
         exists which would constitute an Event of Default. Lessee is not in
         violation of any term of its organization documents. No default or
         event, which with the giving of notice or the passage of time would be
         a default, has occurred under any of the Operating Agreements or any
         other material agreement or instruments to which it or any Subsidiary
         is a party or by which its or any Subsidiary's properties are bound.
         Lessee has fully and timely performed all its material obligations
         thereunder. The right, title and interest of the Lessee thereunder is
         not subject to any defense, offset, counterclaim or claim, and none of
         the foregoing been asserted or alleged against the Lessee with respect
         to any of the Operating Agreements and with respect to such other
         material agreements or instruments except in respect of such defaults,
         defenses, offsets, counterclaims and claims that would not have a
         Material Adverse Effect.

                  (h) All authorizations, consents, approvals, and licenses
         necessary or desirable for the conduct of the business of Lessee and
         its Subsidiaries, including without limitation certificates of
         authorization in states where Lessee is providing telecommunications
         services or allowing the use of the Equipment to provide cable
         services, have been obtained and are in full force and effect.

                  (i) Except as described on the Disclosure Annex hereto, no
         suits, actions or proceedings are pending (or, to Lessee's knowledge,
         threatened) by or before any Governmental Authority against Lessee or
         any of its Subsidiaries and there is no claim that is or would be
         subject to disclosure under the AICPA Statement on Contingent
         Liabilities against or affecting Lessee or any of its Subsidiaries.

                  (j) Lessee has paid all required taxes and discharged its
         liabilities with respect thereto as and when due except in the case of
         taxes and liabilities being

<PAGE>   10

         contested in good faith by appropriate proceedings and in respect of
         which all appropriate reserves have been made in the accounts of
         Lessee.

                  (k) Lessee has made and keeps books, records and accounts
         which are reasonably detailed, and accurately and fairly reflect (or in
         the case of financial books, records and accounts, fairly present) its
         transactions and dispositions of its assets.

                  (l) No representation or warranty made by Lessee in any Lease
         Documents, or any Subsidiary in any Guaranty, and no statement made by
         Lessee in any financial statement, business plan, certificate, report,
         exhibit or document furnished by Lessee to Lessor pursuant to or in
         connection with this Agreement is false or misleading as of the date
         made in any material respect (including by omission of material
         information necessary to make such representation, warranty or
         statement not misleading).

                  (m) Lessee owns or possesses the right to use all patents,
         trademarks, service marks, trade names, copyrights, know-how,
         franchises, software and Software licenses, free from restrictions,
         which are necessary for the operation of its business except where the
         failure to own or possess the right to use any of the foregoing could
         not reasonably be expected to have a Material Adverse Effect.

                  (n) The provisions of each Lease are, or will be, when
         executed and delivered by Lessee, effective to create in favor of
         Lessor a legal, valid and enforceable security interest in each System
         and, when the recordings and filings with the appropriate Governmental
         Authority in the jurisdiction in which the System is from time to time
         located are made, will create a perfected security interest in all
         right, title, estate and interest of Lessee in each System subject to
         each Lease, prior and superior to all other liens, and enforceable
         against creditors of and purchasers from Lessee and against any owner
         or purchaser of real property where any of the Systems is or may be
         located and any present or future creditor obtaining a lien on such
         real property.

                  (o) The place where records of Lessee concerning the Systems
         are located is at 10300 Ormsby Park Place, Suite 405, Louisville
         Kentucky 40223 or 4100 East Mississippi Avenue, Denver, Colorado,
         80246.

                  (p) Lessee and its Subsidiaries are in compliance with all
         environmental laws, regulations, rules, ordinances, permits, orders,
         and other requirements applicable to Lessee and its Subsidiaries and
         their respective operations and the real or personal property owned,
         leased or operated by Lessee and its Subsidiaries, including without
         limitation, all such laws governing use of real property or the
         employment, generation, use, storage, disposal or transportation of
         toxic or hazardous substances or wastes where any non-compliance could
         reasonably be expected to have a Material Adverse Effect. Lessee has
         not

<PAGE>   11

         received notice of, and is not aware of, any violations or alleged
         violations, or any liability or asserted liability, under any such
         environmental laws, with respect to Lessee, its Subsidiaries, or their
         respective businesses or their respective properties where any such
         violation could reasonably be expected to have a Material Adverse
         Effect.

                  (q) Vulcan owns, at the date of this Agreement, at least 35%
         of the stock and other equity interests in the Lessee.

         14. COVENANTS: (a) AFFIRMATIVE COVENANTS. In addition to other
covenants set forth herein, Lessee hereby agrees that from the date hereof until
all amounts owing to Lessor under all Leases are irrevocably paid in full,
Lessee shall keep and perform fully each and all of the following covenants.

                           (i) Lessee shall maintain its existence as a
                  corporation. Lessee shall qualify and remain qualified and in
                  good standing in each jurisdiction in which failure to receive
                  or retain such qualification would have a Material Adverse
                  Effect on the business, operations or financial condition of
                  Lessee individually or Lessee and its Subsidiaries taken as a
                  whole.

                           (ii) Lessee shall comply (and shall procure that its
                  Subsidiaries shall comply) in all respects with all laws and
                  regulations applicable to Lessee, its Subsidiaries, or their
                  respective properties (including, without limitation, any
                  applicable employee benefit law, and tax law, securities law,
                  product safety law, occupational safety or health law,
                  communications and utilities law, environmental protection or
                  pollution control law, and hazardous waste or toxic substances
                  management, handling or disposal law); provided however,
                  Lessee shall not be deemed to be in violation of this Section
                  as a result of any failure to comply if such failure would not
                  result in fines, penalties, injunctive relief or other civil
                  or criminal liabilities or if the failure would not have a
                  Material Adverse Effect.

                           (iii) Lessee shall (and shall procure that its
                  Subsidiaries shall) at all times obtain and maintain in force
                  all authorizations, permits, consents, approvals, licenses,
                  franchises, exemptions and other action by, and all
                  registrations, qualification, designations, declarations and
                  other filings with, any Governmental Authority necessary in
                  connection with execution and delivery of this Agreement,
                  consummation of the transactions herein or therein
                  contemplated, performance of or compliance with the terms and
                  condition hereof or thereof or to ensure the legality,
                  validity and enforceability hereof or thereof or to carry out
                  its business and the business of its Subsidiaries; provided
                  that Lessee shall not be deemed to be in violation of this
                  Section as a result of any failure to comply which would not
                  have a Material Adverse Effect. Without limiting the
                  foregoing, Lessee agrees not to begin providing
                  telecommunications services, or to allow the use of the
                  Equipment to provide cable services, in any state until Lessee
                  has obtained the appropriate certificate of authorization or
                  other authorization required for providers of such services.

<PAGE>   12

                           (iv) Lessee shall pay any required taxes and
                  discharge its liabilities as and when due except for taxes and
                  liabilities being contested in good faith by appropriate
                  proceedings and in respect of which appropriate reserves have
                  been made in the accounts of Lessee.

                           (v) Lessee shall comply in all material respects with
                  the terms of the Operating Agreements and all other material
                  agreements or instruments to which it is a party or by which
                  it or any of its properties are bound.

                           (vi) Lessee shall obtain the written consent of the
                  Lessor prior to the publication or use by Lessee of any
                  advertising, sales promotion, press releases or other
                  publicity matters in which the Lessor's name or logos of the
                  Lessor are mentioned or can be reasonably inferred.

                           (vii) Lessee shall, promptly upon the Lessee becoming
                  aware thereof, give Lessor written notice of the following
                  together with, in each case, a written statement of a
                  responsible officer of Lessee setting forth the details
                  thereof and any action with respect thereto taken or
                  contemplated to be taken by Lessee:

                                    (A) the occurrence of any Event of Default
                           or any event which, with the giving of notice or
                           passage of time or both, would constitute an Event of
                           Default;

                                    (B) any Material Adverse Effect on Lessee,
                           individually or Lessee and its Subsidiaries taken as
                           a whole;

                                    (C) any default by Lessee or any of Vulcan,
                           Marcus or Charter under any of the Operating
                           Agreements; any termination or purported termination
                           thereof; any assignment by any of Vulcan, Marcus or
                           Charter of the Operating Agreements, the Lessee's
                           receipt of any other notice from any of Vulcan,
                           Marcus or Charter with respect to the Operating
                           Agreements as to any event or circumstance that would
                           materially adversely affect the Lessor's interests;

                                    (D) any material default by Lessee or any of
                           its Subsidiaries under any other agreement or
                           instrument to which Lessee or its Subsidiary is a
                           party, or by which Lessee, its Subsidiary, or any of
                           their respective properties may be bound, if such
                           agreement or instrument or the consequences of such
                           default would result in a Material Adverse Effect;

                                    (E) any lien asserted against any of the
                           Systems, any material change in the composition of
                           the Systems, or the occurrence of any other event
                           which would have a material adverse effect on the
                           value of the System or on Lessor's interest therein;

<PAGE>   13

                                    (F) any material change in (including a
                           termination of or default under) the Supplier
                           Agreement by and between Lessee and Lucent
                           Technologies Inc.; and

                                    (G) Within 15 days thereof, the
                           establishment or acquisition of any Material
                           Subsidiary of the Lessee or a Subsidiary of Lessee
                           becoming a Material Subsidiary or the acquisition or
                           purchase of all or substantially all of the business,
                           assets, customers or operations of any other entity.

                           (viii) Lessee shall, after the establishment or
                  acquisition of a Material Subsidiary of the Lessee or a
                  Subsidiary becoming a Material Subsidiary, if so requested by
                  Lessor, deliver to Lessor a Guaranty duly executed by such
                  Subsidiary. If requested by Lessor, Lessee shall cause the
                  Subsidiary to also deliver an opinion of counsel of the
                  Subsidiary's legal counsel.

         (b) NEGATIVE COVENANTS. In addition to the other negative covenants set
forth herein, Lessee hereby agrees that from the date hereof until all amounts
owing to Lessor under all Leases are irrevocably paid in full, Lessee shall keep
and perform fully each and all of the following covenants.

                           (i) Lessee shall not terminate any Supplier Agreement
                  prior to the date set out in Section 4(a).

Lessee shall not change its name or without giving Lessor at least thirty (30)
days advance written notice of such change, and ensuring that any steps that
Lessor may deem necessary to continue the perfection and priority of Lessor's
security interest in any System shall have been taken.

Lessee shall not, directly or indirectly, consolidate with or merge with or
into, any Person (unless the shareholders of Lessee as of the date hereof shall
hold as a group the right to cast at least a majority of the votes of all
holders of voting securities of the resulting or surviving Person on any matter
on which any such holders of voting securities shall be entitled to vote),
without in each case the written prior consent of Lesser, which shall not be
unreasonably withheld or delayed.

                           (iv) Lessee shall not change the fiscal year end of
                  Lessee from [December 31], except with the prior written
                  consent of Lessor, which consent shall not be unreasonably
                  withheld or delayed.

                           (v) Lessee shall not amend, restate or otherwise
                  modify, or violate any terms of, its organizational documents
                  without the prior written consent of Lessor, which consent
                  will not be unreasonably withheld or delayed.

<PAGE>   14

                           (vi) Lessee shall not amend, restate or otherwise
                  modify, directly or indirectly, or violate any terms of any of
                  the Operating Agreements without the prior written consent of
                  Lessor, which consent shall not be unreasonably withheld or
                  delayed.

                           (vii) Lessee shall not enter into any agreements,
                  transaction, or arrangements (other than the Operating
                  Agreements) with any Affiliate of Lessee without the prior
                  written consent of Lessor, such consent not to be unreasonably
                  withheld. Lessee shall not engage in any other transaction or
                  series of transactions with or for the benefit of any
                  Affiliate of Lessee except for (A) transactions that are on
                  terms no more favorable to such Affiliate than would have been
                  obtainable in an arm's length transaction with a Person who is
                  not an Affiliate or (B) other transactions for which Lessee
                  has delivered to Lessor at least thirty (30) days before such
                  transaction a written notice, describing the proposed
                  transaction in reasonable detail, and Lessor has not delivered
                  a written objection to Lessee within twenty (20) days after
                  Lessor's receipt of such notice.

                           (viii) Lessee shall not enter into any new business
                  (other than the telecommunications business) or make any
                  material change in any of Lessee's business objectives,
                  purposes and operations from those contemplated in the
                  business plan dated June 2000 without Lessor's prior written
                  consent, which will not be unreasonably withheld.

         15. DISCLAIMER OF WARRANTIES AND DAMAGES: LESSEE ACKNOWLEDGES THAT (A)
THE SIZE, DESIGN, AND CAPACITY OF EACH SYSTEM AND THE MANUFACTURER AND SUPPLIER
THEREOF HAVE BEEN SELECTED BY LESSEE; (B) LESSOR IS NOT A MANUFACTURER,
SUPPLIER, DEALER, DISTRIBUTOR OR INSTALLER OF ANY SYSTEM; (C) NO MANUFACTURER OR
SUPPLIER OR ANY OF THEIR REPRESENTATIVES IS AN AGENT OF LESSOR OR AUTHORIZED TO
WAIVE OR ALTER ANY TERM OR CONDITION OF ANY LEASE; AND (D) EXCEPT FOR LESSOR'S
WARRANTY OF QUIET ENJOYMENT SET FORTH IN SECTION 11, LESSOR HAS NOT MADE, AND
DOES NOT HEREBY MAKE, ANY REPRESENTATION, WARRANTY OR COVENANT, WRITTEN OR ORAL,
STATUTORY, EXPRESS OR IMPLIED, AS TO ANY MATTER WHATSOEVER INCLUDING, WITHOUT
LIMITATION, THE DESIGN, QUALITY, CAPACITY, MATERIAL, WORKMANSHIP, OPERATION,
CONDITION, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, HIDDEN OR LATENT
DEFECTS, OR AS TO ANY PATENT, COPYRIGHT OR TRADEMARK INFRINGEMENT. AS BETWEEN
LESSEE AND LESSOR, LESSEE LEASES EACH SYSTEM "AS IS, WHERE IS."

LESSOR SHALL HAVE NO LIABILITY TO LESSEE OR ANY THIRD PARTY FOR ANY SPECIAL,
DIRECT, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY SORT INCLUDING,
WITHOUT LIMITATION, DAMAGES FOR PERSONAL INJURY, LOSS OF PROFITS OR SAVINGS,
LOSS OF USE, OR ANY OTHER DAMAGES, WHETHER BASED

<PAGE>   15

ON STRICT LIABILITY OR NEGLIGENCE, WHETHER RESULTING FROM USE OF A SYSTEM OR
OTHERWISE, EXCEPT FOR DIRECT, SPECIFIC DAMAGES FOR LESSOR'S BREACH OF A LEASE OR
FOR PERSONAL INJURY OR PROPERTY DAMAGE TO THE EXTENT CAUSED BY LESSOR'S GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT.

ARTICLE 2A OF THE UCC MAY APPLY TO A LEASE AND LESSEE MAY HAVE CERTAIN RIGHTS
THEREUNDER. IF SO, LESSEE ACKNOWLEDGES THAT SUCH A LEASE IS A FINANCE LEASE AS
DEFINED IN UCC SECTION 2A-103. TO THE EXTENT PERMITTED BY LAW, LESSEE HEREBY
WAIVES, BUT NOT WITH REGARD TO ANY SUPPLIER AND THEIR SUCCESSORS AND ASSIGNS,
ANY RIGHTS OR REMEDIES LESSEE MAY HAVE AGAINST LESSOR UNDER UCC SECTIONS 2A-508
THROUGH 522 INCLUDING, WITHOUT LIMITATION, RIGHTS OF REJECTION, REVOCATION,
CANCELLATION, RETENTION OF SECURITY INTERESTS, AND RECOVERY FOR BREACH OF
WARRANTY.

         16. INSURANCE: At its expense, Lessee shall keep each System insured
against all risks of loss and damage for an amount equal to the installed
replacement cost of such System with Lessor named as a loss payee. Lessee shall
also maintain comprehensive general liability insurance, with Lessor named as an
additional insured. All insurance policies shall be with an insurer having a
rating of "B+" or better by A.M. Best Company, Inc., and be in such form, amount
and deductibles as are reasonably satisfactory to Lessor. Each such policy must
state by endorsement that the insurer shall give Lessor not less than thirty
(30) days prior written notice of any amendment, renewal or cancellation thereof
as it relates to a Lease or a System. Lessee shall, upon request, furnish to
Lessor satisfactory evidence that such insurance coverage is in effect. Lessee
may self insure for such coverages only with Lessor's prior written consent.

         17. CASUALTY: If any System, in whole or in part, is lost, stolen,
damaged or destroyed, or is taken in any condemnation or similar proceeding (an
"Event of Loss"), Lessee shall notify Lessor in writing within ten (10) days of
such Event of Loss. Lessee shall, at its option (a) promptly place the affected
Equipment and Software in good condition and working order, (b) promptly replace
the affected item with like equipment or software in good condition and transfer
clear title and any sublicense to Lessor, or (c) pay to Lessor, within thirty
(30) days of the Event of Loss, an amount equal to the SLV for such affected
Equipment or Software plus any other unpaid amounts then due under the Lease. If
an Event of Loss occurs as to part of a System for which the SLV is paid, a
prorata amount of Rent shall abate from the date the SLV payment is received by
Lessor. Upon payment of the SLV, title to the applicable Equipment and the
sublicense to the applicable Software shall pass to Lessee with no warranties,
subject to the rights, if any, of the insurer.

<PAGE>   16

If Lessor receives any insurance proceeds and Lessee elects not to repair or
replace, Lessor shall apply such proceeds toward the payment of the SLV with any
remaining sums to be delivered to Lessee.

         18. INDEMNITY: Lessee shall indemnify Lessor against, and hold Lessor
harmless from, and covenants to defend Lessor against, any and all losses,
claims, liens, encumbrances, suits, damages, and liabilities (and all costs and
expenses including, without limitation, reasonable attorneys' fees) related to
the Lease including, without limitation, the selection, purchase, delivery,
ownership, condition, use, operation of a System, or violation of a Software
sublicense, or arising by operation of law (excluding any of the foregoing to
the extent caused by the gross negligence or willful misconduct of Lessor).
Lessee shall assume full responsibility for or, at Lessor's sole option,
reimburse Lessor for the defense thereof. This Section shall survive the
termination of the Lease but not longer than the applicable statute of
limitations.

         19. TAX INDEMNITY: The Lease is entered into based upon the assumptions
("Assumptions") that for federal, state, and local income tax purposes, Lessor,
as owner of each System, shall be entitled to deduct, at the highest marginal
rate of tax imposed on corporations, the maximum depreciation or cost recovery
allowances provided in the Internal Revenue Code of 1986, as amended, and under
state and local law in effect on the date Lessee executes the applicable
Schedule. If, in its reasonable opinion, Lessor determines that its net
after-tax economic yield or after-tax cash flow ("Net Economic Return") has been
adversely affected as a result of a change in the Assumptions (a "Loss"), Lessee
agrees to pay to Lessor an amount which will cause Lessor's then Net Economic
Return to equal the Net Economic Return that Lessor would have received had such
Loss not occurred. Lessee shall have no right to inspect the tax returns of
Lessor.

         20. DEFAULT: Any of the following shall constitute an Event of Default:
(a) Lessee fails to pay any Rent or other amount when due under a Lease that is
not paid within ten (10) days of such failure; (b) a breach of any terms of any
Guaranty has occurred, (c) any representation or warranty made by Lessee herein
or in any Lease, or by any of Lessee's Subsidiaries in any Guaranty or any other
related document or any statement made by Lessee or any Subsidiary of Lessee in
any financial statement, certificate, report, exhibit or document furnished by
Lessee to Lessor pursuant to this Agreement or any Guaranty proves to have been
untrue, incomplete, false or misleading in any material respect as of the time
when made or repeated (including by omission of material information necessary
to make such representation, warranty or statement not misleading) and such
untruth, incompleteness, falsity, misleading statement or omission is not
corrected or remedied to the satisfaction of Lessor within thirty (30) days
after the giving or repeating of such representation or warranty; (d) Lessee
defaults in the performance or observance of any indemnification or covenant
contained herein or in any Lease and such default continues for a period of
thirty (30) days thereafter; (e) Lessee attempts to make a Transfer

<PAGE>   17

without Lessor's prior written consent; (f) Lessee dissolves or ceases to do
business as a going concern; (g) Lessee sells, transfers or otherwise disposes
of, in one or a series of transactions, all or a material portion of its assets,
whether now owned or hereafter acquired, or the percentage ownership of the
stock and other equity interests of the Lessee beneficially owned by Vulcan is
less than 25%, or a Change in Control with respect to the Lessee occurs, or
Lessee enters into any transaction which constitutes a Change in Control without
Lessor's prior written consent; (h) Lessee or any other Subsidiary of Lessee
becomes insolvent, makes an assignment for the benefit of creditors, files a
voluntary petition or has an involuntary petition filed or action commenced
against it under the United States Bankruptcy Code or any similar federal or
state law and in respect of an involuntary petition such petition is not
dismissed on or before 30 days after the filing thereof; (i) Lessee fails to
perform its obligations under any other lease or agreement with Lessor after the
expiration of any applicable cure or grace periods, (j) a default, or event or
condition, which with the notice or lapse of time or both would become an event
of default, occurs that gives a creditor of Lessee or any of its Subsidiaries
the right to declare an event of default (howsoever defined) and/or accelerate
payment with respect of any obligation of Lessee or any of its Subsidiaries for
borrowed money (including capitalized or operating lease obligations) in excess
of $10,000, or (k) any of the Operating Agreements is or becomes unenforceable
or is terminated for any reason whatsoever.

         21. REMEDIES: If an Event of Default has occurred, Lessor shall have
the right to exercise one or more of the following remedies set forth below in
addition to any other rights and remedies it may have under any Lease and under
law. Lessor may (a) terminate and/or declare an Event of Default under any Lease
or other agreement with Lessee, (b) recover from Lessee all Rent and any and all
amounts then due and unpaid and (c) recover from Lessee all Rent and other
amounts to become due, by acceleration or otherwise (plus, if the System is not
returned in accordance with Section 9 of the applicable Schedule, an amount
equal to the Estimated FMV). The amounts described in subsection (c) shall be
present valued using the Discount Rate. The amounts set forth in subsections (b)
and (c) above shall be the agreed upon damages ("Lessor's Loss"). Lessor may
also charge Lessee interest on Lessor's Loss from the date of the Event of
Default until paid at the rate of one and one-half percent (1 1/2%) per month,
but in NO event more than the maximum rate permitted by law ("Default Rate");
demand the Lessee return any System to Lessor in the manner provided in Section
9 of the Schedule; and take possession of, render unusable, or disable any
System wherever located, with or without demand or notice or any court order or
any process by law.

Upon repossession or return of a System, Lessor shall have the right to sell,
lease or otherwise dispose of the System, with or without notice and by public
or private sale, and shall apply the proceeds thereof, if any, toward Lessor's
Loss but only after deducting from such proceeds (a) in the case of any
reletting of the System, the rent due for any period beyond the scheduled
expiration of the

<PAGE>   18

Lease; (b) in the case of sale, the Estimated FMV; and (c) all reasonable
expenses incurred by Lessor in repossessing, refurbishing and remarketing of the
System and in enforcing any remedy including, without limitation, reasonable
attorneys' fees and court costs. If the net proceeds available after the
permitted deductions are less than Lessor's Loss, Lessee shall pay Lessor any
deficiency. No right or remedy is exclusive of any other provided herein or
permitted by law or equity. All rights and remedies shall be cumulative and may
be enforced concurrently or individually from time to time.

         22. THIRD PARTY CURE RIGHTS: Each of the Cable Companies will have the
following "cure rights" as third party beneficiaries under this Agreement.
Lessor will give Vulcan, Marcus and Charter at the addresses set out opposite
their respective names in the Definitions Annex, 90 days' advance written notice
prior to taking possession or control of the Equipment or requiring Lessee to
assemble and deliver Equipment to Lessor other than upon expiration of the Term
under the applicable Lease. Within ninety (90) days of the date of Lessor's
notice to the Cable Companies, respectively, each Cable Company may cure any
existing Event of Default and provided all Events of Default are cured within
such 90-day period, Lessor will not take possession or control of the same or
require Lessee to assemble and deliver the same to Lessor so long as no new
Event of Default has occurred and is continuing.

         23. DEFAULT RESERVE: Lessee shall deliver to Lessor a non-refundable
default reserve (the "Default Reserve'") in an amount equal to the final three
month Rent payments which will be due under each Lease. Notwithstanding any
provision to the contrary contained in Section 22 above, Lessor may, without
notice to or demand upon Lessee, apply any amounts on deposit in the Default
Reserve to satisfy any failure to pay under this Agreement or any Lease.
Following any such application of amounts in the Default Reserve by Lessor,
Lessee shall, within five (5) days after written notice from Lessor, deliver to
Lessor funds sufficient to restore the funds on deposit in the Default Reserve
to the amount of the original deposit. Failure to deliver such funds to Lessor
shall constitute an Event of Default under this Agreement and the applicable
Lease and, subject to the terms of Section 22 above, Lessor shall thereafter
have the right to exercise any and all rights and remedies available to Lessor
under this Agreement or the applicable Lease. Lessor may apply the amounts on
deposit in the Default Reserve to Lessee's rent payment obligations for the
final three months of the applicable Term of a Lease. The Default Reserve may be
commingled with other funds of the Lessor and shall earn interest if required by
law. Lessor may deduct any administrative fee permitted by applicable law from
any interest earned on the Default Reserve. Any remaining interest will be
applied to the payment of Rent or other amounts owing hereunder.

         24. ASSIGNMENT: Lessor may, without notice to or the consent of Lessee,
sell, assign, grant a security interest in, or pledge its interest in all or a
portion of a System and/or a Lease and any amounts payable hereunder to any
third party

<PAGE>   19

("Assignee"). Lessee shall, if directed, pay all Rent and other amounts due to
Assignee free from any claim or counterclaim, defense or other right which
Lessee may have against Lessor. Lessor shall be relieved of its future
obligations under the Lease as a result of such assignment if Lessor assigns to
Assignee its interest in the System and Assignee assumes Lessor's future
obligations. WITHOUT LESSOR'S PRIOR WRITTEN CONSENT, LESSEE SHALL NOT ASSIGN,
SUBLEASE, TRANSFER, PLEDGE, MORTGAGE OR OTHERWISE ENCUMBER ("TRANSFER") ANY
SYSTEM OR ANY LEASE OR ANY OF ITS RIGHTS THEREIN OR OBLIGATIONS THEREUNDER OR
PERMIT ANY LEVY, LIEN OR ENCUMBRANCE THEREON. Any attempted non-consensual
Transfer by Lessee shall be void ab initio. No Transfer shall relieve Lessee of
any of its obligations under a Lease.

         25. JURISDICTION, GOVERNING LAW AND WAIVER OF JURY TRIAL: THIS
AGREEMENT AND EACH LEASE SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.
BOTH PARTIES WAIVE ALL RIGHTS TO A JURY TRIAL TO THE EXTENT PERMITTED BY LAW.
Lessee hereby submits for the benefit of Lessor to the jurisdiction of the state
and federal courts in the State of New York in connection with all action and
proceeding arising under or in connection with any of this Agreement and the
Leases.

         26. MISCELLANEOUS: (a) Any failure of Lessor to require strict
performance by Lessee, or any waiver by Lessor of any provision of a Lease,
shall not be construed as a consent to or waiver of any other breach of the same
or of any other provision. (b) If there is more than one Lessee, the obligations
of each Lessee are joint and several. (c) Lessee agrees to execute and deliver
within ten (10) days of its receipt of a written request therefor, any documents
necessary, in Lessor's reasonable opinion, to evidence the intent of a Lease,
and/or to protect Lessor's interest in a System. Lessee appoints Lessor as its
attorney-in-fact for the sole purpose of executing and delivering any UCC
financing statements. (d) If any provision shall be held to be invalid or
unenforceable, the validity and enforceability of the remaining provisions shall
not in any way be affected or impaired. (e) In the event Lessee fails to pay or
perform any obligations under a Lease, upon giving Lessee ten (10) days prior
written notice, Lessor may, at its option, pay or perform such obligation.
Lessee shall reimburse Lessor for any payment made or expense reasonably
incurred by Lessor in connection therewith together with interest thereon
accruing until paid at the Default Rate not to exceed the maximum rate permitted
by law. (f) Time is of the essence in each Lease. (g) Lessee shall pay Lessor
all reasonable costs and expenses, including reasonable attorneys' and
collection fees, incurred by Lessor in enforcing the terms and conditions of a
Lease or in protecting Lessor's rights and interests in a Lease or a System. (h)
LESSOR INTENDS TO COMPLY WITH ALL APPLICABLE LAWS, INCLUDING THOSE CONCERNING
THE REGULATION OF INTEREST. Therefore, no lease charge, late charge, fee or
interest, if applicable, is intended to exceed the maximum amount permitted to
be charged or collected by applicable law. If one or more of such charges exceed
such

<PAGE>   20

maximum, then such charges will be reduced to the legally permitted maximum
charge and any excess charge will be used to reduce the future Rent and/or the
Price of the System or refunded. (i) Each Lease may be executed by one or more
of the parties on any number of separate counterparts (which may be originals or
copies sent by facsimile transmission), each of which counterparts shall be an
original. At Lessor's election, any executed Lease document may be transmitted
by Lessee to Lessor by facsimile transmission. If Lessor executes that faxed
document, the parties intend that the faxed signature of Lessee constitute an
original signature and that the faxed document containing the signatures
(original or faxed) of the parties is binding on the parties. (j) Unless
explicitly otherwise agreed to in a Lease, if Lessee is required to pay Lessor
any amount other than Rent or the SLV, Lessee agrees to pay such amounts within
ten (10) days of its receipt of an invoice, request and/or demand therefor. (k)
Each Lease constitutes the entire agreement between Lessor and Lessee with
respect to the subject matter thereof and supersedes all previous writings and
understandings between Lessee and Lessor relative to a System and the lease
thereof. (l) No agent, employee, or representative of Lessor has any authority
to bind Lessor to any representation or warranty concerning any System and,
unless such representation or warranty is specifically included in a Lease, it
shall not be enforceable by Lessee against Lessor. (m) References to agreements,
documents or instruments hereunder shall include, where the context so requires,
references to such agreements, documents and instruments as amended,
supplemented or varied from time to time (where applicable in accordance with
the terms of this Agreement).

FORM OF CABLE COMPANIES AGREEMENT

To:   GENERAL ELECTRIC CAPITAL CORPORATION
      10 Riverview Drive
      Danbury, Connecticut 06810

Ladies and Gentlemen:

We refer to the Master Lease Agreement dated December ___, 2000 (the "Master
Lease Agreement") between HIGH SPEED ACCESS CORP ("Lessee") and General Electric
Capital Corporation ("Lessor").

We also refer to:

(1)  a Network Service Agreement dated as of November 25, 1998, among Lessee,
     Vulcan Ventures, Inc. ("Vulcan") and Charter Communications, Inc.
     ("Charter") and a Network Service Agreement dated as of May 12, 2000,
     between Lessee and Charter (collectively, the "Network Service Agreement").

(2)  the Programming Content Agreement dated as of November 25, 1998, between
     Lessee and Vulcan (the "Programming Agreement").

(3)  the Systems Access and Investment Agreement dated as of November 25, 1998,
     among Lessee, Vulcan, Charter and Marcus Cable, Inc. ("Marcus") (the
     "Systems Agreement").

Capitalized terms used herein and not otherwise defined shall have the meaning
ascribed thereto in the Master Lease Agreement. Vulcan, Charter and Marcus shall
sometimes be referred to herein collectively as the "Cable Companies" and
individually as a "Cable Company". The Network Service Agreement, the
Programming Agreement and the Systems Agreement shall sometimes be referred to
collectively as the "Operating Agreements" and individually as an "Operating
Agreement".

We understand that Lessor is providing financing to Lessee in respect of
equipment and software that will be used by Lessee to provide services to the
Cable Companies (including, without limitation, head-end equipment) and that it
is a condition precedent to Lessor's agreement to provide such financing that
the Cable Companies provide to Lessor the undertakings, agreements and
confirmations set out in this Letter. Accordingly, for the benefit of Lessor,
each Cable Company, for itself (severally and not jointly) and as to all
Operating Agreements to which it is a party, hereby:

1.   acknowledges receipt of a copy of the Master Lease Agreement and consents
     to Lessee's entering into and performing under the Master Lease Agreement
     and the Leases.

2.   confirms that the terms of the cure rights set out in Section 22 of the
     Master Lease Agreement (entitled "Third Party Cure Rights") are
     satisfactory to Cable Company and serve as the non-disturbance agreements
     referenced in the assignment sections of the Operating Agreements, and, to
     the knowledge of Cable Company, neither any default nor any right of
     termination arises under the terms of the Operating Agreements solely by
     reason of Lessee's entering into the Master Lease Agreement and Leases.

3.   confirms that, to the knowledge of Cable Company, as of the date hereof,
     (a) no default by Lessee exists under the Operating Agreements, and (b) the
     Cable Company has not assigned any of its rights or obligations thereunder.

4.   agrees that the Equipment may be affixed to, or installed upon, premises
     owned or operated by Cable Company (the "Premises"), but shall remain
     personal property notwithstanding the manner in which it is affixed or
     installed.

5.   acknowledges that the Equipment is owned by Lessor and not by Lessee, that
     Cable Company's rights under the Operating Agreements with respect to the
     Equipment (including any rights with respect to insurance coverage or
     proceeds) are subject to Lessor's rights under the Master Lease Agreement
     (subject to Section 22 of the Master Lease Agreement), and that Cable
     Company shall not challenge Lessor's right to repossess the Equipment at
     the end of the 90-day period referred to in Section 22 of the Master Lease
     Agreement.

6.   agrees not to remove any of the Equipment from the Premises at any time
     without Lessor's express prior written consent and not to hinder Lessor's
     actions in enforcing or protecting its title to, interests in and rights
     and remedies with respect to the Equipment (subject to Section 22 of the
     Master Lease Agreement), and to permit Lessor, subject to Lessor's
     agreement not to disclose any non-public information Lessor may obtain
     while on the Premises, to enter onto the Premises to inspect or (subject to
     Section 22 of the Master Lease Agreement) to remove the Equipment
     therefrom, without charge, except for reimbursement for any physical damage
     to the Premises caused by such removal.

7.   waives and disclaims any right that Cable Company may now or hereafter
     have, under the Operating Agreements or otherwise under applicable law,
     except under Section 22 of the Master Lease Agreement, to assert against
     any of the Equipment (and any proceeds thereof) any title or any statutory,
     common law, contractual or possessory lien, including, without limitation,
     rights of levy or distraint for rent.

This Letter shall be governed by the laws of the state of New York. This Letter
may be modified or terminated only in writing signed by the party to be charged,
shall be binding upon the successors and assigns of the Cable Companies and upon
any successor owner or transferee of the Premises and shall inure to the benefit
of the Lessor and its successors and assigns. This Letter may be executed in
counterparts, and a facsimile signature to this Letter by a party shall bind
such party to the same extent as the manual signature of such party. This Letter
shall remain in full force and effect until all Lessee's obligations to Lessor
have been paid in full and the Master Lease Agreement has been terminated.

TERMS AND CONDITIONS (THE FOLLOWING 3 PAGES CONTAIN TERMS AND CONDITIONS WHICH
ARE ALSO A PART OF THIS SCHEDULE)

         The terms and conditions of the Master Lease Agreement between Lessor
         and Lessee referenced above are made a part of this Schedule. Lessor
         and Lessee hereby agree to the terms defined above and further agree as
         set forth herein.

         1. ADVANCE PAYMENT: In addition to the Default Reserve, Lessee shall
         pay to Lessor, upon the execution and delivery of this Schedule, any
         advance payment set forth above ("Advance Payment") in consideration of
         the Lessor holding funds available to purchase the Equipment and obtain
         the Software and as compensation for Lessor's review of Lessee's credit
         and document preparation and negotiation. Upon Lessor's acceptance of
         the Lease, the Advance Payment shall be applied to the payment of Rent
         as set forth above. Any Advance Payment shall be non-refundable if
         Lessee fails to timely provide all documentation or satisfy all
         conditions precedent required by this Lease. Any Advance Payment may be
         commingled with other funds and shall earn interest if required by law.
         Lessor may deduct any administrative fee permitted by applicable law
         from any interest earned on the Advance Payment. Any remaining interest
         will be applied to the payment of Rent.

         2. ACCEPTANCE: The System will be delivered to the Installation Site
         set forth above which is a temporary interim staging area. The

         the System will subsequently be moved to and installed at a number of
         installation sites at various locations ("Final Installation Sites").
         Lessee shall not move any Equipment and/or Software from the
         Installation Site or install any Equipment and/or Software at a Final
         Installation Site without first (a) giving Lessor twenty (20) days
         prior written notice of the location of the applicable Final
         Installation Site including, without limitation, a complete description
         of the of Equipment and/or Software to be located at the site and the
         portion of the Price attributable thereto, (b) executing and delivering
         to Lessor any UCC financing statements required by Lessor, and (c)
         executing and delivering to Lessor a Landlord waiver, if the same has
         not previously been delivered hereunder in respect of the applicable
         Final Installation Site and any other document Lessor reasonably
         believes necessary to protect its interest in the System. The failure
         to comply with the foregoing provisions shall constitute an Event of
         Default.

         Notices shall be sent to:
         Portfolio Manager
         General Electric Capital Corporation
         10 Riverview Drive
         Danbury, CT 06810
         203-749-4530 (fax)

         Lessee agrees to irrevocably accept the System for purposes of this
         Lease on the later of (a) the date the System has been delivered to the
         Installation Site set forth above or (b) the date Lessee executes this
         Schedule. Lessee has requested that Lessor commence the Lease even
         though the System has not been installed. Lessee waives any right to
         terminate the Lease or to withhold Rent based on any installation and
         related performance issues.

         3. MAINTENANCE, USE, AND OPERATION: At all times during the Term, at
         its sole cost and expense, Lessee shall maintain or cause the System to
         be maintained in good repair, condition and working order, ordinary
         wear and tear excepted. Lessee shall use the System and all parts
         thereof for its designated purpose and in compliance with all
         applicable laws. Lessee shall keep the System in its possession and
         control. Lessee may move the System from the Final Installation Site to
         another site in the United States if Lessee (a) gives Lessor at least
         thirty (30) days prior written notice of the move including the
         approximate date of the move and the address of the new Installation
         Site, (b) executes and delivers to Lessor any UCC financing statement
         required by Lessor, and (c) executes and delivers to Lessor any other
         document Lessor believes necessary to protect its interest in the
         System.

         4. MAINTENANCE CONTRACT: If maintenance and/or service ("Maintenance")
         relative to the System being provided by the Supplier is listed as part
         of the Equipment and Software Listing to this Schedule, the cost of
         such Maintenance, ("Maintenance Price"), is included in the Price of
         the System and in the Rent. Lessee agrees that (a) Lessee has selected
         the Supplier providing the Maintenance; (b) Lessor is not responsible
         for providing any such Maintenance; (c) Lessor has not made any
         representations and warranties with respect to Maintenance, except that
         it will pay the Maintenance Price; (d) Lessee will pursue any claim it
         has relative to Maintenance

<PAGE>   34

         against the Supplier and not Lessor; and (e) Lessee's obligations to
         pay Rent and other sums due under the Lease shall remain unconditional
         and not subject to any reduction, delay, setoff, defense or
         counterclaim for any reason including, without limitation, issues
         relative to Maintenance. Lessee or Supplier has delivered to Lessor a
         full and complete copy of the agreement between Lessee and the Supplier
         relative to Maintenance ("Maintenance Contract"). Lessee shall be
         responsible to pay Supplier for any Maintenance under the Maintenance
         Contract if the cost of such Maintenance is not included in the
         Maintenance Price.

         5. PERSONAL PROPERTY: The System is, and shall at all times remain,
         personal property even if the Equipment is affixed or attached to real
         property or any improvements thereon. At Lessor's request, Lessee
         shall, at no charge, promptly affix to the System any tags, decals, or
         plates furnished by Lessor indicating Lessor's interest in the System
         and Lessee shall not permit their removal or concealment. At Lessee's
         expense, Lessee shall (a) at all times keep the System free and clear
         of all liens and encumbrances, except those described in Section 6 and
         those arising through the actions of Lessor, and (b) otherwise
         cooperate to defend Lessor's interest in the System and to maintain the
         status of the System and all parts thereof as personal property. If
         requested by Lessor, Lessee will, at Lessee's expense, furnish a waiver
         of any interest in the System from any party having an interest in the
         real estate or building in which the System is located. Upon giving
         Lessee three (3) days prior written notice, Lessor may inspect the
         System and any related maintenance records during Lessee's normal
         business hours.

         6. TRUE LEASE AND SECURITY INTEREST: (a) Lessor holds title to the
         Equipment and the right to use the Software and Lessor shall be
         entitled to all tax benefits resulting therefrom, and (b) Lessee shall
         have no right, title or interest therein, other than possession and use
         as a lessee and non-exclusive sublicensee. Lessee and Lessor intend
         this Lease to create a true lease and not a security interest. However,
         in the event this Lease is determined by a court to be a lease intended
         as security, Lessee hereby grants to Lessor a first priority security
         interest in Lessee's existing and hereafter acquired right, title and
         interest in, to and under (i) the System, including all additions,
         attachments, accessions, and leased Modifications and Additions (as
         defined in Section 7 below) thereto, and replacements therefor, (ii)
         rights with respect to the Equipment and Software under the applicable
         Supplier Agreement or purchase orders with Lucent, and (iii) all
         products and proceeds of the foregoing including, without limitation,
         insurance proceeds, rents and all amounts payable to or received by
         Lessee with respect to any of the foregoing. The provisions of this
         Section or the filing of any financing statements with respect to this
         Lease shall not be deemed evidence that the parties intended to enter
         into other than a true lease but of an attempt to protect Lessor's
         rights and title.

         7. MODIFICATIONS, ADDITIONS AND ALTERATIONS: After the Commencement
         Date of this Lease and without notice to Lessor, Lessee may, at
         Lessee's expense, alter or modify any item of Equipment with an
         upgrade, accessory or any other equipment that meets the specifications
         of the System's manufacturer for use on or in connection with the
         System ("Modification") or with Software or other associated items or
         materials

<PAGE>   35

         that meet the specifications of such manufacturer and are to be used on
         or in connection with such System ("Addition"). Any other modification
         or addition ("Alteration") shall be permitted only upon written notice
         to Lessor and at Lessee's expense and risk, and any such Alteration
         shall be removed and the System restored to its normal, unaltered
         condition at Lessee's expense prior to its return to Lessor. If not
         removed upon return of the System, any Modification or Addition shall
         become, without charge, the property of Lessor free and clear of all
         encumbrances. Restoration will include replacement of any parts removed
         in connection with the installation of an Alteration, Modification or
         Addition. Any Equipment or Software installed in connection with
         warranty or maintenance service or manufacturer's upgrades provided at
         no charge to Lessee shall be the property of Lessor.

         8. LEASES OF MODIFICATIONS AND ADDITIONS: During the Term of this
         Lease, at Lessee's request, Lessor may elect to lease to Lessee
         Modifications and Additions (as defined above) subject to the terms of
         this Lease. Leased Modifications and Additions are called "CSO
         Equipment". While the CSO Equipment shall be added to and become a part
         of this Lease as of the CSO Commencement Date (as defined below), the
         CSO Equipment Lease Addendum used to document the lease of CSO
         Equipment shall be assigned a separate schedule number. The lease for
         CSO Equipment shall expire at the same time as this Lease. The
         applicable Lease Rate Factor shall be Lessor's then-current Lease Rate
         Factor for similar transactions based upon the remaining length of the
         Term. The rent for CSO Equipment shall be determined by Lessor who
         shall adjust the then-current Rent and notify Lessee in writing of such
         adjustment(s), which shall be effective as of the first day of the
         month following the date of the notice (or the date of the notice if it
         is the first day of the month) ("CSO Commencement Date"). Any
         adjustment notice shall be added to and become a part of this Lease as
         of the CSO Commencement Date.

         CSO Equipment must be ordered by Lessee from a Supplier reasonably
         acceptable to Lessor. On the date any CSO Equipment is delivered to
         Lessee, Supplier shall pass title to such CSO Equipment (other than any
         Software which shall be licensed and/or sublicensed) directly to
         Lessor. Such title shall be good and marketable and free and clear of
         any and all liens and encumbrances of any nature except that of Lessor.
         Lessor shall promptly pay to Supplier the appropriate price of the CSO
         Equipment after the later of (a) the date the CSO Equipment is
         installed and functioning, or (b) Lessor's receipt of a full and
         complete listing of the CSO Equipment and the Supplier's invoice. No
         interest shall be payable by Lessor to Supplier with respect to such
         payment. Lessor's agreement to lease any CSO Equipment is subject to
         the condition that the Price payable to Supplier with respect thereto
         shall not exceed $100,000.00 or be less than $1,000.00, and is subject
         to satisfactory credit review by Lessor of Lessee's credit at the time
         of the CSO.

         9. RETURN OF SYSTEM: (a) At Lessor's request upon the occurrence of an
         Event of Default subject to compliance with Section 22 of the
         Agreement, or (b) if Lessee has not exercised its Purchase Option set
         forth in Section 10 of this Schedule at the end of the applicable Term,
         Lessee shall immediately return the System to Lessor. Lessee shall, at
         its own risk and expense, properly remove, disassemble and pack it for
         shipment,

<PAGE>   36

         load it on board a carrier acceptable to Lessor, and ship the same to a
         destination in the continental United States specified by Lessor,
         freight and insurance prepaid. The returned System shall be in the same
         condition and operating order as existed when received, ordinary wear
         and tear excepted. If Lessee does not return the System to Lessor when
         required, Lessee shall pay to Lessor an amount equal to the
         then-current Rent prorated on a daily basis for each day from and
         including the termination or expiration date of the Lease through and
         including the day Lessor receives the System. Lessee shall pay to
         Lessor any amount reasonably necessary to place the System in good
         repair, condition and working order, ordinary wear and tear excepted.

         10. PURCHASE OPTION: At the expiration of the Initial Term or any Term,
         if Lessee has performed all terms and conditions of the Lease, except
         the return of the System pursuant to Section 9 herein, Lessee shall
         have the right to purchase Lessor's interest in all, but not less than
         all, of the Equipment and all leased Modifications and to receive an
         assignment of all, but not less than all, non-exclusive sublicenses to
         use the Software and Additions, if any, for the Purchase Option Price
         (as defined below) subject to the following terms and conditions
         ("Purchase Option").

         Lessee shall provide written notice to Lessor three (3) months prior to
         such purchase that Lessee has elected to exercise its Purchase Option.
         In any event, upon Lessee's exercise of its Purchase Option, Lessee
         shall purchase the Equipment and all leased Modifications and obtain a
         non-exclusive sublicense to use the associated Software and Additions
         AS-IS, WHERE-IS, WITH ALL FAULTS AND SUBJECT TO THE SAME DISCLAIMERS OF
         WARRANTIES AND LIMITATION OF DAMAGES AS SET FORTH IN THE LEASE. Lessee
         also shall be responsible for the payment of any sales tax or other
         fees in connection with Lessee's exercise of this Purchase Option. The
         Purchase Option Price (including sales taxes or other fees) shall be
         due and payable to Lessor by Lessee on or before the expiration of the
         applicable Term.

         Upon satisfaction by Lessee of the purchase conditions, Lessor's sole
         and exclusive obligations under this Purchase Option shall be to
         deliver to Lessee such title to such Equipment and leased Modifications
         such as Lessor received from the Supplier, and to assign to Lessee a
         non-exclusive sublicense, as described in the Supplier Agreement, to
         use the associated Software and Additions, free and clear of all liens,
         encumbrances and rights of others arising solely out of or created by
         Lessor's actions. Lessor's assignment of the sublicense is limited to
         such sublicense as Lessor can assign without incurring further cost and
         is subject to all applicable terms and conditions of the license and/or
         sublicense set forth in the Supplier Agreement.

         The Purchase Option Price shall be the installed fair market value of
         the System assuming it is in good repair, condition and working order,
         ordinary wear and tear excepted ("FMV"). The FMV shall be determined by
         Lessor and Lessee. If Lessor and Lessee are unable to agree, the FMV
         shall be determined by an independent appraiser selected by Lessor and
         approved by Lessee which approval shall not be unreasonably withheld or
         delayed. Lessee shall bear the fees of the appraiser.

         11. NOTICES: Notices, demands and other communications shall be in
         writing and shall be sent by hand delivery, certified mail (return
         receipt requested), or overnight courier service, or facsimile

GUARANTOR     DIGITAL CHAINSAW, INC.

================================================================================

<PAGE>   39

         1. In consideration of the above named Lessor entering into that
certain Master Lease Agreement bearing the number referenced above ("Agreement")
with Lessee named above and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the undersigned
Digital Chainsaw, Inc., a Florida corporation ("Guarantor"), with offices
located at ___________________________ hereby guarantees the full, prompt and
complete performance by Lessee of all of Lessee's Obligations pursuant to the
Agreement and any Equipment Schedule entered into pursuant to the Agreement
whether executed now or in the future (collectively, "Lease" whether one or
more). "Obligations" shall mean the unpaid installments of rent and all other
obligations, indemnities, and liabilities of the Lessee (including, without
limitation, all reasonable attorneys' fees and expenses), whether direct or
indirect, absolute or contingent, due or to become due, now existing or
hereafter incurred, that may arise under, out of, or in connection with, the
Lease and any other document made, delivered or given in connection with the
Lease. Any sums due hereunder shall be payable on written demand.

         2. This is a continuing, absolute and unconditional guaranty of payment
and performance, and not merely of collection or collectibility. This Guaranty
shall remain in full force and effect until all Obligations are satisfied in
full. Guarantor hereby waives notice of acceptance of this Guaranty and demand
and notice of nonpayment and nonfulfillment of any and all of the Obligations.

         3. Without notice to Guarantor and without affecting Guarantor's
liability hereunder, Lessor may, from time to time, (a) retain or obtain a
security interest in any property to secure any of the Obligations, (b) retain
or obtain the primary or secondary liability of any party or parties, in
addition to Guarantor, with respect to any of the Obligations, and (c) release
its security interest, if any, in all or any property securing any of the
Obligations and permit substitution or exchange for any such property. Guarantor
waives any right to require Lessor to (a) proceed against Lessee or any other
party primarily or secondarily liable for any of the Obligations; (b) proceed
against or exhaust any property securing any of the Obligations; or (c) pursue
any other remedy in Lessor's power, which remedies shall be cumulative. Any
amount received by Lessor from whatever source and applied by it toward the
payment of the Obligations shall be applied in such order of application as
Lessor may elect.

         4. From time to time and without notice to Guarantor, Lessor may amend
or modify any term or condition of the Lease, renew, extend, accelerate or
otherwise change the time for performance of the Obligations or give and make
such exceptions, renewals, settlements, waivers, and compromises as it may deem
proper with respect to any of the Obligations. Exceptions, renewals,
settlements, waivers, and compromises made by Lessor on any one occasion with
respect to any of the Obligations shall not be construed as a bar to or waiver
of, any of Lessor's rights and remedies under this Guaranty with respect to any
Obligations arising on any future occasions.

         5. In the event of death, incompetency, dissolution or insolvency of
Lessee, or if a petition in bankruptcy be filed by or against Lessee, or if a
receiver be appointed for any part of the property or assets of Lessee, or if
any judgment be entered against Lessee, whether or not such event occurs at a
time when any of the Obligations are otherwise due and payable, Guarantor shall
pay to Lessor upon demand the full amount which would be payable hereunder by
Guarantor if all Obligations, including but not limited to the remaining rent
payments, were then due and payable.

         6. Guarantor unconditionally waives any circumstance whatsoever that
might constitute a legal or equitable discharge, release or defense of a
guarantor or surety or that might otherwise limit the liability of Guarantor.
Until all Obligations shall have been satisfied in full, notwithstanding any
payment made by Guarantor hereunder, Guarantor shall not be entitled by
subrogation, indemnity, reimbursement, contribution, or otherwise, to any

such rights. Guarantor waives any benefit of, and any right to participate in,
any security now or hereafter held by Lessor.

         7. Guarantor hereby represents and warrants to Lessor that all
information concerning Guarantor including, without limitation, financial
statements and other financial information furnished to Lessor in connection
with the Lease or this Guaranty, was true, complete and accurate as of the date
of delivery thereof to Lessor, and that all such information remains true,
complete and accurate and there have been no material adverse changes in
Guarantor's financial position as of the date hereof. In the event of any breach
of Guarantor's representations and warranties herein, upon request of Lessor,
Guarantor shall promptly furnish to Lessor such additional security for the
performance of Guarantor's obligations as Lessor may reasonably request. Lessor
may, from time to time, during the term of the Lease request Guarantor's most
recent financial statements and Guarantor shall provide such statements to
Lessor within ten (10) days after any receipt of a written request therefor. No
merger, sale of all or substantially all assets, dissolution, recapitalization,
or change in corporate control, and no assignment for the benefit of creditors
will be made by Guarantor without the prior written approval of Lessor. It is
not necessary for Lessor to inquire into the powers of Guarantor or its
officers, directors or agents acting or purporting to act on its behalf.

         8. Until the Obligations are paid in full, Guarantor covenants and
agrees to comply with and ensure the accuracy of all the agreements, covenants,
and representations in the Lease relating to Guarantor. Further, Guarantor
hereby represents and warrants to Lessor as follows:

                  (a) Guarantor is a duly organized corporation, validly
         existing and in good standing under the laws of the state of its
         formation. Guarantor is duly qualified to do business and is in good
         standing in any jurisdiction in which it is conducting business.
         Guarantor has all requisite right, power and authority to execute and
         deliver to perform its obligations under this Guaranty, and its
         execution, delivery and performance of this Guaranty have been duly and
         validly authorized by all necessary proceedings on the part of
         Guarantor.

                  (b) No authorization, consent, approval, license, exemption or
         other action by, and no legislation, qualification, declaration or
         filing with any Governmental Authority is or will be necessary in
         connection with the execution and delivery of this Guaranty,
         consummation of the transactions herein contemplated, performance of or
         compliance by

<PAGE>   40

         Guarantor with the terms and conditions hereof or thereof or the
         legality, validity and enforceability hereof or thereof where the
         failure to obtain such consent could reasonably be expected to have a
         Material Adverse Effect.

                  (c) The execution and delivery of this Guaranty, the
         consummation of the transactions contemplated herein and the
         performance of or compliance with the terms and conditions hereof or
         thereof by Guarantor do not and will not (i) violate any applicable law
         including any rule, order, injunction, writ, decree or award; or (ii)
         conflict with or result in the termination of or a material breach of
         or a default under any governing document of Guarantor or any agreement
         or instrument to which Guarantor is a party or by which Guarantor or
         its properties is bound. No default or event that, with the giving of
         notice or the passage of time, would be a default, has occurred under
         any material agreement or instruments to which it is a party or by
         which its properties are bound.

         9. No delay or failure on the part of Lessor in the exercise of any
right or remedy shall operate as a waiver thereof, and no single or partial
exercise by Lessor of any right or remedy shall preclude other or further
exercise thereof or the exercise of any right or remedy. No action of Lessor
permitted hereunder shall in any way impair or affect the Guaranty.

         10. Any notice that may be given Guarantor shall be sent by mail,
overnight courier service, or by facsimile transmission sent to the address or
number set forth above and shall be effective when received or upon refusal to
accept receipt. This Guaranty shall be binding upon Guarantor and upon the
successors and assigns of Guarantor and inure to the benefit of Lessor and any
successor and assign of Lessor. Without notice to or the consent of Guarantor,
Lessor may assign all of its rights and interests in and under this Guaranty.
Guarantor may not assign its obligations hereunder.

         11. THIS GUARANTY SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW
YORK. BOTH PARTIES WAIVE ALL RIGHTS TO A JURY TRIAL To the extent permitted by
Law. Guarantor hereby submits for the benefit of Lessor to the jurisdiction of
the state and federal courts in the State of New York in connection with all
action and proceeding arising under or in connection with any of this Guaranty
and the Leases.

         12. Wherever possible, each provision of this Guaranty shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provisions of this Guaranty shall be prohibited by, or invalid under,
such laws, such provision shall be ineffective to the extent of such prohibition
or invalidity, without invalidating the remainder of such provision or remaining
provisions of this Guaranty. Guarantor agrees to pay any reasonable costs and
expenses (including attorneys' fees and expenses) that may be incurred by Lessor
in the enforcement of this Guaranty or the protection of Lessor's rights
hereunder.

                           the end user is responsible for purchasing a license
                           to use CATIA as may be necessary.

                  (iv)     Notwithstanding the foregoing, PlanetCAD shall not

                  hereby grants PlanetCAD the limited right to distribute Source
                  Code of the Translator only to the extent necessary to fulfill
                  any contractual source code escrow obligations of third party
                  agreements relating to the sale and distribution of enterprise
                  versions of on line ASPs as contemplated by Section 3.3. The
                  distribution right set forth herein is subject to (a)

6. DERIVATIVE WORKS

                  As specified in the above Sections 3.3, 4.2 and 5.2, each
                  Party ("Licensee") to whom the other Party ("Licensor") has
                  granted a license under these sections, is allowed to make
                  Derivative Works from the Software so licensed to Licensee.
                  The Parties therefore agree as follows with respect to any
                  such Derivative Works made by Licensee according to the
                  provision of the corresponding license:

         6.1      Ownership of Derivative Works. The Parties agree that all
                  right, title and interest in and to all or part of the
                  Derivative Works made by Licensee pursuant to the licenses
                  granted in the Agreement shall be owned exclusively by
                  Licensor. Licensee understands and agrees that such Derivative
                  Works made by Licensee, as well as any portion thereof, shall
                  be the sole property of Licensor from date of creation and, to
                  the extent permitted by law, shall be considered as works made
                  for hire under the copyright laws of the United States of
                  America. To the extent an assignment is necessary and that
                  this assignment cannot be made at present, Licensee agrees to
                  assign to Licensor all of its right, title and interest in and
                  to these Derivative Works, and any part thereof, and in and to
                  all copyrights, patents and other proprietary rights Licensee
                  may have in such Derivative Works.

<PAGE>   9

                           The Parties however agree that the creator of a
                           Derivative Work shall remain the owner of such
                           Derivative Work should such Derivative Work be
                           Software (i) developed by or for licensee and using
                           all or part of the licensed Software as a component
                           of an application (i.e. embedded or included in whole
                           or in part in such other Software), and (ii) as long
                           as such Software contains new functionality,
                           significant value added, or creates a new function
                           that is packaged as a standalone product and which
                           user interface is different from existing Software.
                           The Parties also agree that application of an
                           alternative interface technology if this interface is
                           not combined with other significant application level
                           functionalities shall not be considered as having
                           significant added value.

         6.2      Delivery Obligations of the Parties.

                  (i)      At the end of each quarter, in the event that either
                           Party has made any Derivative Work, such Party shall
                           deliver to Licensor one copy of the Source Code of
                           such Derivative Work, in a sealed and dated envelope,
                           in the form of a CD-ROM, or other appropriate media.

                  (ii)     Such items shall be sent to Licensor, as applicable,
                           by international registered mail to the following
                           address:

                           or may be delivered to either Party by e-mail
                           transmission if agreed to in advance by the receiving
                           Party.

                           The Parties agree to make their best reasonable
                           commercial efforts to comply with the above process
                           which aims to facilitate the tracing and evidencing
                           of the Derivative Works. Should any Party miss some
                           delivery with that respect, it will make its best
                           reasonable commercial efforts to do it as soon as
                           possible; in any case, both parties recognize that
                           should any of them not deliver Derivative Work under
                           this process, the other Party will keep all its
                           rights and actions to request the transfer of
                           ownership to any work that such other Party deems a
                           Derivative Work under this Agreement.

         6.2      Know-How. The Parties hereby acknowledge and agree that any
                  and all rights to Know-How developed or shared under this
                  Agreement by either Party shall be jointly owned by the
                  Parties and may be used by either party in the operation of
                  their respective business during and following termination of
                  this Agreement.

7. MAINTENANCE AND SUPPORT

                  PlanetCAD, as the case may be) will provide the Licensee with
                  four years maintenance and support as described in the

                  product is marketed and for the twelve month period following
                  cessation of marketing activities relating to such product; or
                  (b) except if PlanetCAD provides twelve month advance notice
                  of discontinuation of WBM Software.

                  of Control of PlanetCAD to the benefit of a Competitor of
                  Dassault Systemes, Dassault Systemes will not be required to
                  continue providing maintenance or support services, as set
                  forth in Schedule B, for the Translator and/or CBD Software.

                           INDEMNIFICATION, AS SET FORTH IN SECTION 11.2, AND
                           (iii) THE CONFIDENTIALITY PROVISIONS SET FORTH IN
                           SECTION 13.1: IN NO EVENT SHALL EITHER PARTY BE
                           LIABLE FOR ANY SPECIAL, EXEMPLARY, INCIDENTAL,

                           INCLUDING ANY LOST PROFITS, LOST SAVINGS, LOST STAFF
                           TIME OR OTHER ECONOMIC DAMAGES ARISING OUT OF OR IN
                           CONNECTION WITH THIS AGREEMENT, EVEN IF ADVISED OF
                           THE POSSIBILITY OF SUCH DAMAGES.

                  11.1.2   IN NO EVENT SHALL EITHER PARTY BE LIABLE UNDER THIS

                           [***].

         11.2     Intellectual Property Infringement Indemnification. Each Party
                  agrees to hold the other Party, its subsidiaries,
                  distributors, assignees and Affiliates, and their respective
                  officers, directors, employees, and shareholders
                  (collectively, the "Indemnities") harmless from and against
                  any claim of any nature, including, but not limited to,
                  administrative, civil or criminal procedures, which is or may
                  be made or raised against a Party's Indemnities by any third
                  party that the use or distribution of the Software that is the
                  subject of this Agreement and owned by the other Party,
                  infringes or violates any third party's patent, copyright,
                  trade secret or other intellectual property right in any
                  country. Indemnification hereunder shall cover all damages,
                  regardless of their nature, settlements, expenses and costs,
                  including costs of investigation, court costs and attorneys'
                  fees. The payment of any indemnification shall be contingent
                  on:

                  (i)      A Party giving prompt written notice to the other
                           Party of any such claim or allegation;

                  (ii)     Cooperation by the indemnified Party with the other
                           Party in its defense against the claim; and

                  (iii)    The indemnified Parties obtaining the other Party's
                           prior written approval of any settlement, if any, by
                           the indemnified Party of such matters, such approval
                           not to be unreasonably withheld.

<PAGE>   16

                  Notwithstanding the foregoing, neither Party shall have the
                  obligation to indemnify the other for any claims of
                  infringement based on any modification by the latest version
                  of its Software, or from the combination of its Software with
                  any other program, to the extent such claim would not have
                  arisen without such combination or from use of the unmodified
                  Software.

         11.3     Additional Remedies. If the operation, distribution or use of
                  any Software that is the subject of this Agreement becomes, or
                  is likely to become, the subject of a claim involving the
                  infringement or other violation of any patent, copyright,
                  trade secret, or other intellectual property rights of any
                  third party, the Parties will jointly determine in good faith
                  what appropriate steps can be agreed upon, with a view towards
                  curing such infringement or other violation, at the Software
                  owner's sole charge. Such steps may include, but are not
                  limited to:

                  (i)      The owner securing the right for the other Party to
                           continue using the Server Software, or

                  (ii)     The owner replacing or modifying the Software so that
                           it becomes non-infringing.

                  If no other option is reasonably available, the owner of the
                  Software agrees to use its best efforts to withdraw, at its
                  sole expense, the infringing Software from the market.

12. TERM AND BREACH OF MATERIAL OBLIGATIONS

         12.1     Term. This Agreement shall come into force as of the Effective
                  Date, and shall remain valid until the expiration of the last
                  copyright or other protection available in any Software herein
                  licensed.

         12.2     Breach of Material Obligations. In the event a Party fails to
                  perform any of its material obligations under this Agreement,
                  the non-breaching Party has given written notice to the other
                  Party of such failure to perform, and the breach is not cured
                  within a sixty day period from receipt of the notice, the
                  non-breaching Party may terminate any and all of its
                  obligations to provide maintenance and support, as set forth
                  in Section 7, to the breaching Party.

13. MISCELLANEOUS

         13.1     Confidentiality. All communications and information disclosed
                  by one Party to the other Party under this Agreement shall be
                  subject to the terms and conditions of the CNDA.
                  Notwithstanding anything to the contrary in the CNDA, all
                  information relating to the Source Code of the CBD Software
                  and Derivative Works thereof and the WBM Software and
                  Derivative Works thereof and the Translator shall be deemed to
                  be Confidential Information under the CNDA even though they
                  are not marked confidential.

         13.2     Freedom of Action. Except as otherwise provided, nothing
                  contained in this Agreement shall be construed to limit or
                  impair any right of either Party to enter into similar
                  agreements with other parties, or to develop, acquire, license
                  or market, directly or indirectly, other products or services,
                  competitive with those offered by the other Party.

         13.3     Termination of Third Party Licenses. In the event either
                  Dassault Systemes' or PlanetCAD's rights in a third party
                  license that is part of Software subject to the terms of this
                  Agreement is terminated, Dassault Systemes and PlanetCAD will
                  reasonably assist each other in attempting to obtain a
                  satisfactory solution to the loss of such rights. In the event
                  such a solution is not obtained, despite the good faith
                  efforts of the Parties, the Party whose rights in the third
                  party license were terminated may terminate the license
                  granted hereunder as to the specific Software so affected.

         13.4     Additional Instruments. Notwithstanding termination of this
                  Agreement, the Parties covenant and agree to execute and
                  deliver any additional instruments or documents necessary to
                  carry out the general intent of this Agreement, including
                  without limitation patent assignments or any other assignments
                  necessary to evidence the ownership of Intellectual Property
                  contemplated hereby or any such additional instruments or
                  documents, including such instruments as may be required by
                  the laws of any jurisdiction, now or in effect or hereinafter
                  enacted, that may affect a Party's rights, title or interest,
                  as applicable, in and to any of the software governed hereby.

         13.5     Irreparable Injury. Each Party acknowledges and agrees that
                  each covenant in this Agreement pertaining to confidential
                  information and ownership of intellectual property is
                  reasonable and necessary to protect and preserve the rights of
                  the other Party in its confidential information and
                  intellectual property, and that any breach by such Party of
                  the terms of this Agreement may result in irreparable injury
                  to the other Party. Each Party, therefore, subject to a claim
                  of laches, estoppel, acquiescence or other delay in seeking
                  relief, consents and agrees that the other Party shall be
                  entitled to seek and obtain a temporary restraining order and
                  a permanent injunction to prevent a breach or contemplated
                  breach of this Agreement and waives any requirement that the
                  other Party post a bond in connection with seeking such
                  injunctive relief.

                  sales representative, or employment relationship between the
                  Parties. Neither Party has the authority to act as agent for
                  the other Party or to conduct business in the name of such
                  other Party or make statements, warranties or representations

         13.9     Severability. If any term or other provision of this Agreement
                  is deemed invalid, illegal or incapable of being enforced by

         13.12    Applicable Law, Venue. This Agreement shall be governed by,
                  and construed in accordance with, the Laws of the State of New
                  York, applicable to contracts executed in and to be performed
                  entirely within that state (without regard to the conflicts of
                  Law provisions thereof). This Agreement shall not be governed
                  by the U.N. Convention on Contracts for the International Sale
                  of Goods. The parties hereto hereby (a) submit to the
                  exclusive jurisdiction of any court of competent jurisdiction
                  sitting in the State of Delaware, The City of Wilmington for
                  the purpose of any Action arising out of or relating to this
                  Agreement brought by any party hereto, and (b) agree, to the
                  fullest extent permitted by applicable law, to waive, and not
                  to assert by way of motion, defense, or otherwise, in any such
                  Action, any claim that is not subject personally to the
                  jurisdiction of the above-named courts, that its property is
                  exempt or immune from attachment or execution, that the Action
                  is brought in an inconvenient forum, that the venue of the
                  Action is improper, or that this Agreement may not be enforced
                  in or by any of the above-named courts.

         13.13    Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY WAIVES
                  TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT
                  MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY ACTIONS OR
                  PROCEEDINGS DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN
                  CONNECTION WITH THIS AGREEMENT, OR THE TRANSACTIONS
                  CONTEMPLATED HEREUNDER.

         13.14    Counterparts. This Agreement may be executed in one or more
                  counterparts, each of which when executed shall be deemed to
                  be an original but all of which taken together shall
                  constitute one and the same agreement.

         13.15    No Waiver. The failure of either Party to enforce any
                  provision of this Agreement shall not constitute a waiver of
                  the right to subsequently enforce such provision, or any other
                  provision of this Agreement.

         13.16    Force Majeure. Neither Party shall be held liable for any
                  failure to perform any of its obligations under this Agreement
                  for as long as, and to the extent that such failure is due to
                  an event of force majeure. An event of force majeure shall
                  include general strikes, lockouts, acts of God, acts of war,
                  mobilization of troops, fire, extreme weather, flood, or other
                  natural calamity, embargo, acts of governmental agency,
                  government or any other laws or regulations.

         13.17    Expenses. Except as expressly provided for in this Agreement,
                  each Party shall bear its own expenses incurred in connection
                  with this Agreement, including without limitation travel and
                  living expenses incurred by that Party's employees.

         13.18    Assignment; Subcontracting; Third Party Beneficiaries.

                  (a)      This Agreement may be assigned or otherwise
                           transferred, by operation of law or otherwise without
                           the express written consent of PlanetCAD and Dassault
                           Systemes, but in such event the assigning Party shall
                           give notice to the non-assigning Party and the
                           non-assigning Party shall have the right to terminate
                           its maintenance and support obligations under this
                           Agreement within the 30 day period following receipt
                           of such notice.

                  (b)      Either Party may assign or otherwise transfer all or
                           part of this Agreement to any of its Affiliates and
                           for as long as it remains an Affiliate; provided that
                           no such assignment shall relieve a Party of any of
                           its obligations under this Agreement. In the event
                           there is a change of Control of an Affiliate which
                           terminates its status as an Affiliate of the party to
                           this Agreement, and this Agreement has been assigned
                           to such an Affiliate, this Agreement shall be
                           assigned back to the party within 6 months of the
                           effective date of the change of Control.

                  (c)      Either Party may subcontract services necessary to
                           perform the obligations set forth in this Agreement

                           to comply with all terms and conditions of this
                           Agreement; and (ii) the subcontracting Party shall
                           have obtained prior approval from the other Party,
                           which will not be unreasonably withheld, (a) of its
                           subcontractors, and (b) the method the subcontracting
                           Party will make the Source Code of any Software that

                           subcontractors, in the event access to such Source
                           Code is necessary.

                  (d)      This Agreement shall be binding upon and inure solely
                           to the benefit of the Parties hereto and their
                           permitted assigns, subcontractor or transferee, and
                           nothing herein, express or implied, is intended to or
                           shall confer upon any other person, including,
                           without limitation, any union or any employee or
                           former employee of either Party, any legal or
                           equitable right, benefit or remedy of any nature

                           of employment for any specified period, under or by

                  in connection with any product, service, promotion, public
                  announcement, advertisement or other publication, without
