               Flextronics International Manufacturing Contract

This Manufacturing Agreement ("Agreement") is entered into this 3rd day of
November, 1998 by and between Replay Networks having its place of business at
1003 Ewell Court, Palo Alto, California  94303 ("Replay Networks") and
Flextronics International USA, Inc., 2090 Fortune Drive, San Jose, CA  95131
("Flextronics").

Replay Networks has created a market for Replay Networks' Products and is solely
responsible for the sales and marketing of the Products.  Flextronics has
developed processes and practices for manufacturing products for many different
electronic applications and at Replay Networks' request desires to manufacture
Replay Networks' Products in accordance with Replay Networks' specifications.
Replay Networks acknowledges that Flextronics' expertise is manufacturing and
that Flextronics' responsibility related to the Replay Networks' Products is
limited to this extent.  The parties agree as follows:

1.0  WORK LICENSE

Flextronics agrees to use reasonable commercial efforts to perform the work
(hereinafter "Work") pursuant to purchase orders or changes thereto issued by
Replay Networks and accepted by Flextronics.  Work shall mean to procure
components, materials, equipment and other supplies and to manufacture,
assemble, test, and products (hereinafter "Products") pursuant to detailed
written specifications for each such Product which are provided by Replay
Networks and accepted by Flextronics and to deliver such Products.  For each
Product or revision thereof, written specifications shall include but are not
limited to bill of materials, schematics, assembly drawings, process
documentation, test specifications, current revision number, and approved vendor
list (hereinafter "Specifications") as attached hereto.

Flextronics is granted by Replay Networks a non-exclusive license during the
term of this Agreement to use all of Replay Networks' patents, trade secrets and
other intellectual property required to perform Flextronics' obligations under
this Agreement.

2.0  FORECASTS, ORDERS, MATERIAL PROCUREMENT

2.1  Forecast.  Replay Networks shall provide Flextronics, on a [***] basis, a
rolling [***] Product order forecast.

2.2  Purchase Orders.  Replay Networks will issue written purchase orders [***]
per calendar [***] which specify all Work to be completed within a minimum [***]
period commencing on the date of the purchase order. Each purchase order shall
reference this Agreement, and the applicable written Specifications as described
in Section 1.0. Purchase orders shall normally be deemed accepted by
Flextronics, provided however that Flextronics may reject any order that
represents a significant deviation from Replay Networks' historical ordering
volumes or shipment dates. Flextronics shall notify Replay Networks of rejection
of any purchase order within [***] working days of receipt of such order.

Replay Networks may use its standard purchase order form to release items,
quantities, prices, schedules, change notices, specifications, or other notice
provided for hereunder.  The parties agree that the terms and conditions
contained in this Agreement shall prevail over any terms and conditions of any
purchase order, acknowledgment form or other instrument.

2.3  Material Procurement.  Replay Networks' accepted purchase orders will
constitute authorization for Flextronics to procure, using standard purchasing
practices, the components, materials and supplies necessary for the manufacture
of Products ("Inventory") covered by such purchase orders.

In addition, Replay Networks authorizes Flextronics to purchase, in amounts
beyond the amount necessary to fill accepted purchase orders, the components,
materials, and supplies:  (i)  with lead times greater than [***] days at
the time the order is placed ("Long Lead Time Components") plus [***] to
account for the order, shipment, receipt and manufacturing time and,  (ii)
purchased in quantities above the required amount in order to achieve price
targets ("Economic Order Inventory"), and (iii) purchased in excess of
requirements because of minimum let sizes available from manufacturers ("Minimum
Order Inventory").  Together these are called "Special Inventory".

Flextronics may purchase Long Lead Time Components sufficient to meet all
deliveries under the purchase orders and Product forecast in effect at the time
the order with the supplier is placed, and may reasonably purchase Minimum Order
Inventory even if greater than the amount necessary to meet purchase orders and
Product forecast.  Economic Order Inventory shall be purchased by Flextronics
only with the prior approval of Replay Networks.  Flextronics may, from time to
time, hold Long Lead Time Components and finished goods in inventory to increase
Replay Networks flexibility.  The components and quantities of all such
inventory will be documented in a separate letter and signed by both Flextronics
and Replay Networks.

Replay Networks will be responsible for all Inventory and Special Inventory
purchased by Flextronics under this Section 2.1 under the conditions provided
elsewhere in this Agreement.

3.0  SHIPMENTS,  SCHEDULE CHANGE, CANCELLATION

3.1  Shipments.  All Products delivered pursuant to the terms of this Agreement
     ---------
shall be suitably packed for shipment in accordance with Replay Networks'

   [***]                [***]       [***]       [***]


Any purchase order quantities increased or rescheduled pursuant to this Section
may not be subsequently  increased or rescheduled without the prior written
approval of Flextronics.  All other changes in quantity or shipment date require
Flextronics' prior written consent and shall be subject to an inventory carrying
charge of [***] per month for finished Product, and Inventory and Special
Inventory procured to support the original schedule.  Allowable quantity
increases are subject to material availability.  Flextronics will use reasonable
commercial efforts to meet quantity increases.  If there are extra costs to meet
a schedule increase in excess of the above limits, Flextronics will inform
Replay Networks for its approval in advance.

3.3  Cancellation.  Replay Networks may not cancel any portion of Product
     ------------
quantity of an accepted purchase order without Flextronics' prior written
approval, not to be unreasonably withheld. If the parties agree upon a
cancellation, Replay Networks will pay Flextronics for Products, Inventory, and
Special Inventory affected by the cancellation as follows: (i) [***] of the
contract price for all finished Products in Flextronics' possession, (ii) [***]
of the cost of all Inventory and Special Inventory in Flextronics' possession
and not returnable to the vendor or usable for other Replay Networkss, whether
in raw form or work in process, less the salvage value thereof, (iii) [***] of
the cost of all Inventory and Special Inventory on order and not cancelable,
(iv) [***] vendor cancellation charges incurred with respect to Inventory and
Special Inventory accepted for cancellation or return by the vendor, and (v)
expenses incurred by Flextronics related to labor and equipment specifically put
in place to support Replay Networks' purchase orders.

Flextronics will use reasonable commercial efforts to return unused Inventory
and Special Inventory and to cancel pending orders for such inventory, and to
otherwise mitigate the amounts payable by Replay Networks.
