ITEM 5. OTHER EVENTS.

        On May 1, 2000, Hybrid Networks, Inc. and Sprint/United Management
Company, a subsidiary of Sprint Corporation, entered into a Purchase of
Equipment and Services Agreement whereby Hybrid agreed to sell products and
services to support the wireless multi-channel multipoint distribution system
(MMDS) being developed by Sprint for markets in the United States. The
agreement sets forth (i) the terms of orders that Sprint or any Affiliate
(as defined) may place with Hybrid during the term of the agreement and (ii)
the requirements that Hybrid must meet to supply products and services.

        In general, the agreement provides that Sprint will furnish Hybrid
with monthly non-binding rolling forecasts of expected orders for equipment
over the next 180 days. Hybrid must accept any orders that do not materially
exceed the forecast or certain manufacturing capacity or lead times. Hybrid
must pay specified damages and other amounts if orders are not shipped by
prescribed dates.

        Payment by Sprint for products shipped by Hybrid under the contract
is due within 30 days after shipment, except that, for headend (base station)
equipment incorporated into a new System (as defined), Hybrid will invoice
40% of the purchase price on shipment, 45% after the equipment satisfies
certain substantial completion test procedures (expected to take
approximately 60 days) and the balance (15%) after the equipment satisfies
certain final acceptance test procedures. Prior to deployment of any System
by Sprint, Hybrid and Sprint will perform end-to-end testing of the System in
Phoenix.

        Hybrid will to provide installation, technical support,
trouble-shooting and other services, as well as training and manuals. In
general, Hybrid may submit invoices for services monthly.

        Sprint agreed that it will pay Hybrid $10 million by December 31,
2000 for equipment and services purchased under the contract (including all
equipment and services purchased by Sprint or certain affiliates after
September 30, 1999), provided that the equipment achieves prescribed
substantial completion milestones. This purchase commitment will be
terminated, however, if Sprint and Hybrid are unable to demonstrate that the
system in Phoenix is operating in accordance with certain specifications and
has satisfied certain substantial test procedures within 45 days after May 1,
2000.

        Hybrid has agreed to develop new products and to enhance existing
products according to certain requirements, including prescribed development
schedules, milestones and testing procedures. These developments may require
substantial expenditures. If Sprint pays for any aspect of the development,
Sprint will own the aspect paid for and the related intellectual property.

        The agreement provides for certain warranties and indemnities by
Hybrid and for additional remedies in the event of certain manufacturing
defects. Hybrid is required to support the headend equipment it produces
under the agreement for eight years after the last shipment.

        Hybrid agreed to provide as soon as possible, but in no event later
than June 30, 2001, an application programming interface and reference
design, and to license the interface and design to certain third parties on
commercially reasonable terms so that they can produce competing routers and
related equipment (but not headends) that interface with Hybrid's headends.

        The agreement has a term of five years and is automatically renewable
thereafter for successive one-year periods unless either party gives
appropriate notice to the other party at least 180 days prior to the then
expiration dates. Either party may terminate the agreement upon a material
breach by the other party and after certain cure periods have elapsed. If
the agreement is terminated by Sprint as a result of a material breach by
Hybrid within certain prescribed categories (or if any such breach occurs
after the occurrence of a Hybrid Insolvency, as defined), Sprint will have a
license, and access, to Hybrid's technology for use by Sprint and its
suppliers in connection with the provision of wireless broadband

services to Sprint's and its Affiliates customers, other than broadband
access providers owning wireless frequencies.

        The agreement requires Hybrid to give Sprint most-favored-customer
status.

         Supplier will ship the Equipment ordered on the shipment date contained
in any Order accepted by Supplier.

         3.3      DAMAGES FOR DELAY.

                  (A) If shipment from Supplier to Sprint's designated location
         is delayed more than 5 consecutive calendar days beyond the designated
         shipment date, Supplier agrees to pay liquidated damages calculated as
         1/2% of the price of the Order, for each business day of delay after
         the initial 5 days, up to a maximum of 15% of the total amount of such
         Order to the extent such Order is comprised of CPE Equipment and up to
         a maximum of 10% of such Order to the extent such Order is comprised of
         Base Station Equipment. Liquidated damages will be calculated only on
         the portion of the Order delayed and the portion of the Order Sprint is
         unable to use because a portion of the Order is delayed.

                  (B) Supplier will ship at least 80% of all Orders scheduled
         for shipment in a consecutive 3-month period in accordance with the
         terms of this Section 3.0 prior to or within 5 business days of the
         scheduled shipment date for such Orders (the "Fulfillment Standard").
         Supplier's compliance with the Fulfillment Standard will be measured in
         each rolling 3-month period. In the event Supplier fails to meet the
         Fulfillment Standard, then in the subsequent month Supplier must ship
         at least 80% of all Orders scheduled for shipment during that month in
         accordance with the terms of this Section 3.0 on or prior to the
         scheduled shipment date for such Orders. If Supplier fails to comply
         with the foregoing sentence, then in the subsequent month any Order
         that is shipped after its scheduled shipment date will be shipped for
         next day delivery at Supplier's costs. Supplier's failure to achieve
         the Fulfillment Standard during any 4 consecutive measurements will
         constitute a material breach of this Agreement, which Supplier has no
         further right to cure under Section 17.2, and giving Sprint the
         immediate right to terminate.

                  (C) Supplier will not be responsible for delays caused by the
         failure of a carrier designated by Sprint to meet its shipment
         schedule.

Supplier will provide (to the extent technically possible) Furore Enhanced
Equipment in the form of the removal, modification or addition of standards,
features, functionality, or service capabilities. Sprint and Supplier will
negotiate in good faith a reasonable development budget and time schedule for
the shipment of such enhancements. Supplier will notify Sprint within 30 days of
the date of any Sprint request for an enhancement whether Supplier is willing to
develop the enhancement at its cost, in which case the enhancement will be the
exclusive property of Supplier, or whether Supplier intends to charge Sprint in
accordance with Section 38.2 for the development of the enhancement, in which
case the development of the enhancement will be subject to the provisions of
Section 9.1. Enhancements that would not increase Supplier's cost of performance
will be provided at no charge, the parties will follow the procedures
established in Sections 6.0 and 7.0 for the development and acceptance of
enhancements.

         8.2      PRIORITY.

         As long as the dollar amount of purchases made by Sprint under this

Supplier during the prior 6-month period, Supplier will provide Sprint with
development priority over any other Supplier customer. If Sprint believes that
Supplier is not providing Sprint enhancements priority, Sprint will notify
Supplier in writing that Sprint is dissatisfied with Supplier's scheduling
priority. Supplier will respond within l0 days to Sprint's concerns and if
Sprint remains dissatisfied, Supplier will provide Sprint and its auditors the
access to verify that the work of Sprint is being scheduled and performed with
priority over any other Supplier customer. If Sprint is not receiving priority,
then Supplier will modify its development schedule so that Sprint enhancements
are performed first and pay for the cost of the audit.

         If Supplier notifies Sprint of any third party request to undertake a
material development effort and Sprint cannot, within 5 business days of
Supplier's notice, identify a development need that would interfere with the
third party's request, then Sprint may not subsequently require development
priority that would interfere with Supplier's contractual obligation to perform
development for such third party. Supplier's notice is required to disclose only
the existence of the request for the development effort, the associated time
schedule, estimated man hours for the development effort, and a statement
notifying Sprint of the consequences for failing to respond within 5 business
days. In no event will Supplier allow a development effort for a third party to
interfere with a development effort for Sprint that was scheduled prior to the
third party's request for development.

         Supplier will, at Supplier's sole expense, deposit the Escrow
Technology that is utilized in each piece of Equipment sold or licensed,
respectively, to Sprint under this Agreement with a mutually acceptable
independent escrow agent pursuant to a written escrow agreement signed by Sprint
and Supplier and consistent with the terms of this Agreement. Additionally,
Supplier will automatically deposit any updates, upgrades, or other revisions of
the Escrow Technology with such escrow agent pursuant to the escrow agreement
between the parties. Supplier will provide updated information to the escrow
agent no later than 30 days after Supplier first sells the Equipment that
incorporates the updated information. The escrow agent will give Sprint written
notice of any deposit by Supplier. Sprint will be entitled to inspect the
deposit or have a third party inspect the deposit on Sprint's behalf. The source
code delivered to the escrow agent will be in a form suitable for reproduction
by Sprint.

         20.3     RELEASE OF ESCROW TECHNOLOGY.

     The escrow agreement described in this Section 20.0 will provide that upon
the happening of any of the events listed in Sections 3.3(b), or 17.2.1 (a), (b)
or (c) giving rise to Sprint's right to terminate this Agreement, and upon the
effective date of the termination of this Agreement (an "Escrow Termination
Event"), Sprint will give written notice to the escrow agent and Supplier,
specifying the event, and the escrow agent will thereupon deliver to Sprint all
deposited escrowed materials within 10 days not having received an objection
from the Supplier. Any such notice must prominently reference this Agreement and
be entitled: "IMPORTANT COMMUNICATION RE: ESCROW TERMINATION EVENT." Any dispute
regarding the Escrow Termination Event shall be resolved by arbitration in
accordance with Schedule 20.3. In the event that arbitration results in finding
that an Escrow Termination Event has occurred, Supplier will withdraw its
objection to the release of the Escrow Technology.

         20.4     NON-ESCROW TECHNOLOGY

         Supplier shall grant Sprint access to the Non-Escrow Technology if an
arbitrator finds that an Escrow Termination Event has occurred, but such access
to the Non-Escrow Technology ("Non-Escrow Technology Access") shall not
interfere with Supplier's use of the Non-Escrow Technology necessary to support
contractual relationships.

         20.5     MAINTENANCE RELEASE OF TECHNOLOGY

         Notwithstanding Sections 20.3 and 20.4, the escrow agent will
immediately release the Escrow Technology to Sprint and Supplier will
immediately provide Non-Escrow Technology Access to Sprint upon receipt of
notice from Sprint specifying the termination of this Agreement arising out of
an Escrow Termination Event set forth in Sections 17.2.1 (a) or (b)(ii) and in
spite of any objection from Supplier. If the arbitrator subsequently determines
that Sprint was not entitled to the Escrow Technology and Non-Escrow Technology
Access, then Sprint will promptly (i) return such materials to Supplier, (ii)
certify to Supplier the destruction of any copies, (iii) pay Supplier's out of
pocket costs incurred in connection with the removal and replacement of the
Escrow Technology, and (iv) reimburse Supplier for any maintenance fee revenue
avoided by Sprint as a result of the release, subject to Sprint's right to
damages for any Supplier breach of its obligations under this Agreement. Sprint
agrees that, in the event it obtains access to the Technology pursuant to this
Section 20.5, Sprint will use the Technology solely for the purpose of
maintaining the Equipment.

         20.6     INSOLVENCY RELEASE OF TECHNOLOGY

         Immediately upon the occurrence of a Supplier Insolvency, Supplier
shall promptly give notice to Sprint that the Supplier Insolvency exists. Any
such notice must prominently reference this Agreement and be entitled:
"IMPORTANT COMMUNICATION RE: SUPPLIER INSOLVENCY." If, upon or following such
notice, and while the Supplier Insolvency persists, (i) Supplier commits an act
constituting breach under Section 17.2.1 (a), (b) or (c), and (ii) Sprint gives
notice to Supplier and the escrow agent that such a breach occurred during a
Supplier Insolvency, then, and in spite of any objection from Supplier, (A) the
escrow agent will immediately release the Escrow Technology to Sprint and
Supplier will immediately provide Non-Escrow Technology access to Sprint (the
"Insolvency Release") and (B) Sprint may then exercise its rights under the
license of Section 20.1, but such exercise may continue only for so long as the
Supplier Insolvency persists. However, if the Supplier Insolvency persists for
more than 90 days following the Insolvency Release, then Sprint's right to use
the Escrow Technology and Non-Escrow Technology under the license of Section
20.1 shall become perpetual.

         Any dispute regarding the occurrence of the Supplier Insolvency, an
Insolvency Release and/or Splint's right to gain access to the Technology
pursuant to this Section 20.6 shall be resolved by arbitration in accordance
with Schedule 20.3.

         20.7     BANKRUPTCY OF SUPPLIER

         If Supplier or its successors or representatives, including any
bankruptcy trustee, rejects or terminates this Agreement under Title 11, Section
365 of the United States Code, or any replacement provision therefor, Sprint
shall have the right to retain all or any portion of its rights under this
Agreement and any agreement supplementary hereto including, but not limited to,
the escrow agreement. Sprint's rights include, but are not limited to, all
rights to continue to use and have access to the Escrow Technology and the
Non-Escrow Technology including, upon written request by Sprint, the right to
obtain the Escrow Technology from Supplier (or its trustee in bankruptcy) and
have Supplier (or its trustee in bankruptcy) provide Non-Escrow Technology
Access from Supplier, and the right to obtain the Escrow Technology from the
escrow agent immediately upon such rejection or termination.

         If Supplier or its successors files a, or becomes the subject of an
involuntary, petition in bankruptcy, then unless and until Supplier (or its
trustee in bankruptcy, if one has been appointed) rejects this Agreement,
Supplier (or its trustee in bankruptcy) shall (i) perform all obligations of
Supplier under this Agreement and the escrow agreement and (ii) not interfere
with the proper release of the Escrow Technology by the escrow agent to Sprint
in accordance with the terms of the Agreement.

         20.8     NO WARRANTY

         THE ESCROW TECHNOLOGY AND NON-ESCROW TECHNOLOGY, IF AND WHEN PROVIDED
TO SPRINT, ARE PROVIDED TO SPRINT "AS IS." OTHER THAN A WARRANTY OF
COMPLETENESS, SUPPLIER MAKES NO OTHER WARRANTIES ON THE ESCROW TECHNOLOGY AND
NON-ESCROW TECHNOLOGY.

         21.0     PRICE AND PRICE WARRANTY

         21.1     PRICING.

         Pricing will be in accordance with the pricing disclosure letter from
Supplier to Sprint dated May 1, 2000 (the "Pricing Letter"). Any customs duties,
freight, sales, use, excise or similar taxes with respect to the Deliverables
will be detailed as a separate line item on each applicable invoice. The prices
in the Pricing Letter do not include applicable customs duties, taxes, shipping,
and special packaging and labeling.

         21.2     MOST FAVORED CUSTOMER STATUS.

     Sprint will be Supplier's most favored customer. Accordingly, Supplier's
pricing to Sprint will be equal to or better than that charged to each other
customer of Supplier for the same or comparable Equipment or Services after all
reductions, rebates, volume discounts or adjustments are applied.

         (A) In the event that the Net Price charged to any of Supplier's other
customers for any Deliverables is lower than the Net Price previously charged to
Sprint for such Deliverables, Sprint is entitled to receive the benefit of such
lower Net Price with respect to any Deliverables invoiced to Sprint from the
date of which such lower Net Price was invoiced to such Supplier's other
customers. In addition, such lower Net Price will be applied to all subsequent
Orders of such Deliverables by Sprint during the remainder of the term of this
Agreement, subject to future reductions under this Agreement.

         (B) All invoices to Sprint for Deliverables to which a lower Net Price
is applicable under this Section 21.0, will be reissued by Supplier within 30
days after it is determined that Sprint is entitled to receive the benefit of a
lower Net Price. The reissued invoice must indicate the difference between the
Net Price originally invoiced to Sprint and the reduced Net Price, together with
all applicable sales or other tax reductions attributable to the price
reduction. The reduction in Net Price made in accordance with this Section 21.0
will be reflected on all future invoices issued by Supplier to Sprint (subject
to future reductions under this Section 21.0).

         (C) On an annual basis throughout the term of this Agreement commencing
on January 1, 2001, Supplier will be required to audit its pricing of all
Deliverables provided to all of its customers in the preceding calendar year and
deliver to Sprint a certification (the "MFC Certificate") signed by an
authorized officer of Supplier, certifying that this Section 21.0 has been
adhered to and identifying what, if any, Net Prices charged to Sprint have been
decreased as a result of compliance with this Section 21.0. The MFC Certificate
will be provided to Sprint within 60 days after the close of each calendar year.
Sprint has the right to have Supplier's compliance with this Section 21.0
verified annually. Such verification shall be performed by an independent,
reputable and nationwide public accounting firm chosen by Sprint and reasonably
acceptable to Supplier. Since the conduct of the audit may expose the accounting
firm to Supplier's Proprietary Information, such accounting firm, prior to
conducting the audit, will enter into a non-disclosure agreement reasonable
acceptable to Supplier. In addition to any other terms reasonably required by
Supplier, such non-disclosure agreement shall provide that the accounting firm
will provide to Sprint only the minimum amount of information necessary for
Sprint to verify Supplier's compliance with this Section 21.0.

22.0     SOFTWARE LICENSE

         Upon payment of the applicable license fee, Supplier hereby grants to
Sprint a perpetual, fully paid up, worldwide, non-exclusive right to install and
have others install, sell, and use the Software on the following terms:

         (a)      The Software is licensed in object code format only;

         (b)      The license to the Software may be transferred only in
                  connection with a transfer of the Equipment on which the
                  Software is contained or operating;

         (c)      Sprint and its transferees will not decompile or reverse
                  engineer the Software and Sprint will obtain agreements
                  binding the transferees of such Software to the terms of this
                  Section 22.0.

23.0     INVOICING AND PAYMENT

         23.1     INVOICE REQUIREMENTS.

SPRINT PROPRIETARY INFORMATION - RESTRICTED


                                       17
<PAGE>



         (a)      cancel the Order as to those Deliverables and accept a
                  corresponding reduction in the Commitment;

         (b)      accept the Deliverables, at an equitable reduction in price;

         (c)      reject the Deliverables and return to Supplier at Supplier's
                  expense and require shipment of replacements which meets the
                  specifications set forth in this Agreement.

         25.3     RIGHT TO INSPECT AND TEST.

         Splint's right to inspect and test does not relieve Supplier from its
testing, inspection and quality control obligations.

26.0     WARRANTIES

         26.1     EQUIPMENT WARRANTY.

         Supplier warrants that the Equipment will be new and throughout the
Warranty Period:

         (a)      will conform to the Specifications;

         (b)      will be free from defects in materials and workmanship;

         (c)      will be free from liens and encumbrances.

         26.2     EQUIPMENT WARRANTY TERM.

         Supplier will promptly repair or replace the non-conforming Equipment,
at Supplier's discretion and expense. Sprint will return any such non-conforming
Equipment to Supplier in accordance with the procedures set forth on Schedule
26.2. Equipment corrected or replaced is warranted under this Section for the
remaining portion of the original Warranty Period.

         26.3     PATTERN DEFECTS.

         (A) In the event that more than 12% of any lot, batch or other
separately distinguishable manufacturing run of Base Station Equipment (or 10%
of any lot, batch or other separately distinguishable manufacturing run of
receiver cards forming a part of Base Station Equipment) or 6% of any lot, batch
or other separately distinguishable manufacturing run of CPE Equipment (each a
"Batch") shipped to Sprint is found to be defective with the same or similar
Defects occurring during the first 5 years after shipment of any part of such
Batch (whether or not occurring all at the same time) (a "Pattern Defect"),
Sprint may notify Supplier of the Pattern Defect. Upon receipt of such
notification, Supplier will have 30 days in which to determine the cause of such
Pattern Defect and 90 days to remedy such Pattern Defect (the "Pattern Defect
Cure Period"). Pursuant to such remediation, Supplier will promptly repair or
replace any and all Equipment that was part of the Batch subject to the Pattern
Defect, whether in Sprint's or any Affiliate's inventory or in Sprint's or any
Affiliate's distribution channels, including Equipment held by end-users.
Supplier will reimburse Sprint for any removal and reinstallation costs
associated with the repair or replacement of the Batch. For purposes of this
Section 26.3, a Defect will be considered the same or similar to another Defect
if (i) both Defects involve the failure of the Equipment to achieve the same or
similar Equipment specification (ii) both Defects arise out of the manner in
which the Equipment is assembled or (iii) both Defects arise out of the manner
in which the Equipment is designed.

         (B) In the event that a Pattern Defect is not remedied within the
Pattern Defect Cure Period, Sprint will have the right to terminate this
Agreement and/or any then outstanding Order(s) and/or to resell to Supplier for
cash payment (at Sprint's original cost) any and all Equipment in Sprint's and
any Affiliate's inventory or distribution channel(s) and that are subject to any
such Pattern Defect(s), provided that if Supplier is diligently pursuing a cure,
Sprint will allow Supplier an additional 30 days to remedy such Pattern Defect
prior to taking such actions. In the event that such Pattern Defect is not
remedied, Supplier agrees to remove, at its cost, and repurchase (at Splint's
and any Affiliate's original cost therefor) from Sprint any Equipment
repurchased or otherwise recalled by Sprint due to Supplier's failure to remedy
any such Pattern Defect. Sprint will not recall any Equipment without reasonable
prior written notification to (but not the consent of) Supplier.

         (C) Notwithstanding anything contained in this Agreement to the
contrary, in the event that, with respect to any Equipment, a recall or similar
demand, request or suggestions is issued by the Consumer Product Safety
Commission or other Governmental Authority, Supplier will immediately remove,
repurchase and recall (at its own cost and expense) any such Equipment whether
then held by Sprint, any Affiliate, or end-user.

         26.4     BACKWARDS COMPATIBILITY.

         Enhanced Equipment will be backwards compatible with Existing
Equipment. Future Enhanced Equipment will be backwards compatible with two prior
generations of Equipment. Backwards compatible means the previous version of the
Equipment will remain fully functional up to the performance levels to which it
was performing immediately prior to the introduction of an Equipment
enhancement.

         26.5     DISCLAIMER.

ALL OF THE WARRANTIES SET FORTH IN THIS SECTION 26.0 ARE IN LIEU OF, AND
SUPPLIER DISCLAIMS, ALL OTHER WARRANTIES OR REPRESENTATIONS, EXPRESS AND
IMPLIED, ORAL OR WRITTEN, INCLUDING WITHOUT LIMITATION, ANY IMPLIED WARRANTY OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR OF NONINFRINGEMENT. WITHOUT
LIMITING THE GENERALITY OF THE FOREGOING, SUPPLIER MAKES NO WARRANTY THAT THE
OPERATION OR PERFORMANCE OF ANY DELIVERABLE WILL BE UNINTERUPTED OR ERROR-FREE
OR WILL MEET SPRINT'S REQUIREMENTS.

27.0     LIABILITY AND INDEMNIFICATION

         27.1     THIRD PARTY CLAIMS.

         Each party agrees to defend, pay all third party judgments,
settlements, expenses, and costs (including reasonable attorney fees) and
indemnify, and hold the other party and its Indemnitees harmless from any suit,
claim or proceeding brought against the other party and its Indemnitees by any
third party (excluding affiliates of the indemnified party, but including any
personnel of Sprint or Supplier) for personal injury (including death), or
damage to property, to the extent the loss, destruction, injury or death is
caused by a negligent act or omission or willful misconduct by the indemnifying
party or its Indemnitees, subcontractors or agents. Any infringement of an
intellectual property right shall not be covered under this subsection, but is
covered in subsection 27.4.

         27.2     PRODUCT LIABILITY CLAIMS.

         Supplier will defend, pay all third party judgments, settlements,
expenses and costs (including reasonable attorney fees) and indemnify and hold
the Sprint Indemnitees harmless against any claim brought against the Sprint
Indemnitees for personal injury (including death) to the extent the claim is
based upon an allegation that any Deliverable is defective or dangerous or any
warning associated with such Deliverable is lacking or inadequate.

         27.3     TAXES AND BENEFITS.

         Supplier will indemnify, hold harmless and defend the Sprint
Indemnitees from all claims by any employees, subcontractors, or agents utilized
by Supplier for the performance of this Agreement, or any government or
governmental agency, relating to payment of employment taxes and employee
benefits, including without limitation, any penalties and interest which may be
assessed against the Sprint Indemnitees with respect to such taxes and benefits.
Supplier will similarly indemnify and defend the Sprint Indemnitees from all
claims by any person or governmental agency which arise directly or indirectly
from any failure by Supplier to comply with applicable workers' compensation
coverage on Supplier's employees, subcontractors and agents.

         27.4     INFRINGEMENT.

         (A) Supplier Indemnity. Supplier agrees to defend, indemnify the Sprint
Indemnitees for any damages incurred by the Sprint Indemnitees and hold the
Sprint Indemnitees harmless from all third party claims brought against the
Sprint Indemnitees based on any third party claim that the Deliverables as
shipped by Supplier to Sprint pursuant to this Agreement, or any use or sale or
offer to sell or importation of the Deliverables in a manner intended by
Supplier or permitted sale by the Sprint Indemnitees of such Deliverables,
constitutes an infringement of a U.S. patent, a copyright infringement, or
misappropriates a trade secret.

         Supplier will have no liability, however, for any claim of infringement
to the extent caused by: (i) modification of any Deliverable other than
modifications made by or with the approval of Supplier; (ii) the use or sale or
offer to sell or importation of a Deliverable in connection with another product
(including software) or service (the combination of which causes the
infringement) not provided by Supplier unless the use was intended by Supplier;
or (iii) Supplier's compliance with Sprint's specific instructions.

         If, as a result of a claim of infringement for which Supplier has an
indemnity obligation, the sale or use of Deliverables is enjoined, or the Sprint
Indemnitees must cease use based on a claim of infringement, Supplier will, at

SPRINT PROPRIETARY INFORMATION - RESTRICTED


                                       19
<PAGE>



Supplier's option and expense, either (i) procure for the Sprint Indemnitees the
right to use the applicable Deliverables, (ii) modify the Deliverables so they
become non-infringing within a time frame reasonably acceptable to Sprint, or
(iii) replace the Deliverables with substantially equivalent non-infringing
Deliverables. In the event Supplier, using commercially reasonable efforts, is
unable to do either (i), (ii) or (iii), the Sprint Indemnitees will cease using
the Deliverables and return the same to Supplier. Supplier will then refund to
the Sprint Indemnitees the amount paid by Sprint for such infringing
Deliverables.

         (B) Sprint Indemnity. Sprint agrees to indemnify and hold the Supplier
Indemnitees harmless from all third party claims brought against the Supplier
Indemnitees or its permitted assigns based upon any claim that any Deliverable
or Supplier's manufacture, use, sale or offer for sale thereof infringes any
U.S. patent, constitutes a copyright infringement, or misappropriates a trade
secret, if such infringement or alleged infringement would not have occurred or
be alleged to have occurred but for Supplier's compliance with Sprint's
specifications or instructions.

         (C) SOLE REMEDY. THE PROVISIONS OF THIS SECTION 27.4 SET FORTH EACH
PARTY'S SOLE AND EXCLUSIVE OBLIGATIONS, AND THE OTHER PARTY'S SOLE AND EXCLUSIVE
REMEDIES, WITH RESPECT TO INFRINGEMENT OR MISAPPROPRIATION OF INTELLECTUAL
PROPERTY RIGHTS OF ANY KIND.

         27.5     INDEMNIFICATION PROCEDURES.

         (A) Notice of Claims. Promptly upon becoming aware of any matter which
is subject to the provisions of Sections 27.1, 27.2, 27.3 or 27.4 (a "Claim"),
the party seeking indemnification (the "Indemnified Party") must give written
notice of such Claim to the other party (the "Indemnifying Party"), accompanied
by copies of any written documentation regarding the Claim received by the
Indemnified Party.

         (B) Defense of Claims. The Indemnifying Party will retain the right at
its option, to compromise or defend at its own expense and with its own counsel,
any such Claim. The Indemnified Party will have the right, at its option, to
participate in the settlement or defense of any such Claim, with its own counsel
and at its own expense; but the Indemnifying Party will have the right to
control such settlement or defense; provided, however, that the Indemnifying
Party will not enter into any settlement that imposes any liability or
obligation on the Indemnified Party without the Indemnified Party's prior
written consent. The parties agree to cooperate in any such settlement or
defense and to give each other full access to all relevant information, subject
to the execution of appropriate and reasonable confidentiality agreements. In
the event that the Indemnifying Party fails to notify the Indemnified Party of
the Indemnifying Party's intent to take any action within 15 days after receipt
of notice of a Claim or fails to proceed thereafter in good faith with the
prompt resolution of the Claim, the Indemnified Party (without waiving any
rights to indemnification hereunder) may defend such Claim and may enter into
any good faith settlement without the prior written consent of the Indemnifying
Party, and the Indemnifying Party will reimburse the Indemnified Party on demand
for all reasonable costs and expenses incurred by the Indemnified Party in
defending and settling such Claim. The Indemnified Party will notify the
Indemnifying Party prior to taking any such action.

         (C) Conditions. Neither party will have an obligation to indemnify the
other if the Indemnified Party fails to notify the Indemnifying Party of a Claim
promptly and to provide reasonable cooperation, information, assistance, and
sole control for the handling and defense of the Claim, and such failure
materially prejudices the Indemnifying Party.

         28.0     LIMITATION ON LIABILITY

         28.1 EXCLUSION OF DAMAGES.

         IN NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER FOR ANY INDIRECT,
INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOST PROFITS,

Hybrid Base Station Equipment and no other third party base station equipment.
Supplier shall license the Interface to such third parties on commercially
reasonable terms acceptable to Supplier. The terms of such license shall be
consistent with the practice in the telecommunications services industry for the
license of comparable technology, equipment and the intellectual property

reasonable if they prohibit such third party from developing, manufacturing and
selling an alternative to the CPE on market competitive terms and conditions).
Any dispute regarding the terms of such license shall be resolved by arbitration
in accordance with Schedule 20.3. The Interface shall include all
specifications, schematics, bill of material, source and object code or other
technical information and rights, necessary or useful to allow a third party to
manufacture an alternative to the CPE which interfaces with the Hybrid Base
Station Equipment consistent with the Specifications. Supplier is not required
to license third parties to make, use, or sell Base Station equipment of any
type. Supplier retains the right to refuse to license a third party against whom

property rights, is actively in discussions or negotiations with such third

Agreement, and may only make copies necessary for performing this Agreement. The
parties will make a good faith effort to label all Proprietary Information as

     Information prior to first receiving such information from the owner of the

                                MASTER TEST PLANS

1.0      INITIAL SYSTEM VERIFICATION

Sprint and the Supplier will perform end-to-end System verification prior to
deployment of any System hereunder on Supplier's System deployed and operating
in Phoenix. Sprint will provide access to its System in Phoenix and each party
will provide resources required to satisfy the initial System verification as
promptly as possible. Initial System verification will test all functional and
performance capabilities of the System against the Specifications and will
include those tests contemplated for Substantial Completion. In the event the
parties are unable to demonstrate that the System in Phoenix is operating in
accordance with its Specifications and has satisfied the Substantial Completion
testing procedures within 45 days from the Effective Date, the Commitment will
be terminated.

2.0      SUBSTANTIAL COMPLETION TESTING

The purpose of Substantial Completion Testing is to confirm the operational
capability in accordance with the Specifications of the System in a "real world"
environment. The test plan will clearly identify tests to be run, procedures to
monitor and measure system performance, equipment necessary to undertake tests,
and expected results and roles and responsibilities.

The test will simulate real world environmental conditions to the extent
possible, including, performance under load, reasonable interference, and other
environmental conditions. To accomplish this, Sprint will provision at least
eight customers (or test sites) per sector in each System. All users in MDS-1
sectors shall broadcast on a common RF channel and all users in MDS-2 sectors
shall broadcast on a common RF channel. Test will be performed for various
upstream channel widths. The tests must test for all minimums, maximums and
operational. All test results must be valid and based on objective criteria.

These tests will include, but will not be limited to, the following types of
tests:

A. FIELD INSTALLATION AND INTEGRATION ACCEPTANCE TESTS

- -        Power Up Procedures

- -        Transmit tests (Repeated for each CMD and CMD channel)

- -        Diagnostic Testing

- -        Alarm Testing (monitor system shall be tested to ensure that cyber
         manager alarm message logs are created and passed to network)

- -        Software Installation (including, but not limited to functionality,
         interoperability and performance testing of the software.)

- -        Initialization

- -        Call Processing Testing

- -        Remote Unit Installation and Test

- -        Routing Tests

- -        Equipment, including third party equipment and all functional elements
         thereof, shall be tested (including RF, Hybrid (and IP infrastructure
         elements)

- -        Interoperability Testing, (including, but not limited to
         interoperability to various vendor platforms, routers, etc.)

- -        Provisioning interface test (ensure correct operation of customer and
         network provisioning capabilities)

- -        Network management interface test (ensure correct operation of the
         network management capabilities).

- -        Cold-start. (To ensure the system is recoverable, in the event of loss
         of system power or system maintenance, a cold-start of all components
         will be performed. After reactivation, basic regression testing of the
         above tests will be performed to ensure continued proper operation.)

B. SYSTEM PERFORMANCE TESTS

- -        Super - Cell Capacity. For a representative sample of downstream
         channels and a representative sample of upstream channels, throughput
         testing will be performed to ensure deployed capacity is within design
         margins.



SPRINT PROPRIETARY INFORMATION - RESTRICTED

                                       3
<PAGE>


- -        Delay. For a representative sample of downstream channels and a
         representative sample of upstream channels, latency testing will
         be performed to ensure the System is within design margins.

- -        R.F Coverage. Each downstream RF channel and each upstream RF channel,
         testing will be performed to ensure the link budget (including fade
         margin) is within design margins, assuming the input/output
         specifications of 3rd party RF components are met.

- -        Bit Error Rate. Each downstream channel and each upstream channel,
         testing will be performed to ensure system BER (with FEC) is within
         design margins.

3.0      FINAL ACCEPTANCE TEST CRITERIA

For each market, Final Acceptance will occur if, all (but not less than all) of
the following are true:

- -        Operational requirements set forth in Section 1.0, subsection A above
         shall be retested and complied with as part of Final Acceptance
         testing.

- -        In total, in each market, there are no more than "X" Performance Events
         during the relevant "Burn-In Period". For the purposes hereof "X
         Performance Events" means (i) 10 E l events in the first 2 markets to
         achieve Substantial Completion; (ii) 8 El events in the next 2 markets
         to achieve Substantial Completion; iii) 4 E 1 events in any additional
         such Systems thereafter to achieve Substantial Completion and (iv) 4 E

                          TRANSPORTATION ROUTING GUIDE

ROUTING: The carriers listed below shall be used for the inbound and outbound
movement of materials to, from, and between Sprint locations and suppliers.

BILLING: All freight charges which are directly, or indirectly, the
responsibility of Sprint should be billed third party to Sprint Accounts
Payable, P.O. Box 5409, Kansas City, MO 64131. Purchase of insurance coverage
from transportation carriers is NOT authorized.

DOCUMENTATION: All shipping documents should reference Purchase Order, Work
Order, or Cost Center number. International paperwork should be verified by
Sprint's Transportation Department prior to shipment.

COMPLIANCE: Failure to comply with Sprint's Transportation Routing Guide
instructions will result in excess freight chargebacks to your company.
Shipments routed by means other than the guidelines within will be charged back
to the supplier unless previously agreed to by both Parties.

SPRINT TRANSPORTATION: Please refer any questions to Sprint's Transportation
Department to the following Transportation Specialist:

Tom Conrow, Domestic Ground & Air Shipments            913/791-7394
Zoe Morgan, International Shipments                    913/791-7395
Ginger Farrell, International Shipments                703/904-2784

Small package surface shipments should be routed via United Parcel Service or
Roadway Package System. These would be shipments weighing under 150 pounds in
total weight and meeting carrier size and weight restrictions as follows:

- -        150 pounds maximum weight per package
- -        130 inches combined length and girth

more information regarding third party billing.

Surface shipments weighing over 150 pounds should be routed with the appropriate
LTL carrier as shown on page 2 of the Routing Guide.

Ladies and Gentlemen:

We understand that Sprint/United Management Company (together with its
affiliates, "Sprint") is a party to an equipment purchase agreement (the
"Purchase Agreement") with Hybrid Networks, Inc. ("Hybrid"). The Purchase
Agreement provides that in the event Hybrid is unable to satisfy its material
obligations to Sprint, Sprint is entitled to obtain the technology and
manufacturing capabilities of Hybrid for purposes of continuing to manufacture,
maintain and sell equipment previously manufactured and maintained by Hybrid.

As a key supplier of Hybrid, Sprint has our assurances that in the event Sprint
exercises its manufacturing and maintenance rights under the Purchase Agreement,
we will continue to act as a supplier to Sprint in substantially the same manner
as we have previously served Hybrid.

                                                     Very Truly Yours

III.     ADVANCE REPLACEMENT

Supplier will ship replacement Equipment to Sprint immediately upon Sprint's
request if Sprint has issued a purchase order to cover Equipment being replaced.
After replacement, the failed Equipment is to be shipped back to Supplier. An
invoice will be generated at the time of shipment of the replacement Equipment.
The invoice will be credited when the failed Equipment is received complete by
Supplier. The invoice will be sent to Sprint if the defective Equipment is not
returned complete within 60 days of invoice generation.

IV.      ANNUALIZED FIELD FAILURE RATES

Sprint will be responsible for the cost of removing/reinstalling Equipment,
except to the extent the Annualized Field Failure Rate ("AFFR") exceeds the
thresholds set forth in the table below. Supplier will reimburse Sprint for
Equipment removal/reinstallation costs associated with Defects to the extent the
AFFR exceeds the thresholds set forth in the table below. In no event will
Supplier be charged more than $60 for any removal/reinstallation cycle. The AFFR
will be calculated separately for each category of Equipment.

         (i) The AFFR threshold for Base Station Equipment where the cumulative
shipments for that Equipment type exceed 500 is:

501 to 1000 units                                             40 units
1001 units                                                    5%

The Annualized Field Failure Rate will be first calculated at the end of the
first full month following the Effective Date and each month thereafter
throughout the term of the Agreement.

The Annualized Field Failure Rate is the number, expressed as a percentage,
obtained by multiplying:

         (a)       the quotient of:

4. ETA AND CSR.

         In the event that emergency or non-emergency technical support provided
from Supplier's technical support center is not sufficient to resolve an El
Emergency Condition or an E2 Emergency Condition, a P 1 Major Condition or a P2
Significant Problem, Supplier must send a technically qualified person or
persons to the site of such emergency condition or problem to assist Sprint's
employees in solving such condition or problem. Supplier's technically qualified
person or persons must be on-site as soon as practicable after the mutual
determination that the support provided by Supplier's technical assistance
center is not sufficient to resolve the condition, but in no event more than 24
hours after such determination, or at such later time as may be determined by
Sprint. A CSR will be submitted by Sprint to request a repair of the emergency
condition or the non-emergency problem, or to request the addition of a Software
or Equipment Upgrade or other Software or Equipment Enhancement. Sprint's CSRs
will define the condition or problem and state whether Sprint considers the CSR
to be for a Software/Equipment Upgrade or Software/Equipment Enhancement.
Changes to the System resulting from CSRs must be fully tested and accepted in
accordance with the Specifications. Supplier must respond to the submission of a
CSR by Sprint within five (5) business days, acknowledging receipt of the CSR,
confirming or denying agreement with Sprint's assessment of whether the CSR may
be considered a Software or Equipment Upgrade or a Software or Equipment
Enhancement and summarizing Supplier's intended actions to handle the CSR. A CSR
may result in System fixes, or enhancements, resulting in Equipment
modifications reasonably acceptable to Sprint.
