                     TERMS OF INVENTORY FOR EQUITY EXCHANGE

Notwithstanding the provisions of the Agreement, the following shall apply:

Inventory Return

1.   Net One agrees to return a minimum of $1.5 million of its existing FVC
     product inventory to FVC ("RETURNED INVENTORY") pursuant to the terms of an
     Equity Investment Agreement as of Amendment No.2 Effective Date. In
     consideration of the above mentioned product, FVC will issue Net One shares
     of FVC common stock in the amount to be determined by dividing the value of
     Returned Inventory by the average closing price of FVC common stock for the
     thirty (30) days prior to Amendment No.2 Effective Date, as reported on the
     Nasdaq SmallCap. The FVC issued shares will not be registered shares. FVC
     shall use its best efforts to register such issued shares to Net One in a
     prompt and timely manner.

2.   Returned Inventory shall be valued at the price of the product and support
     service originally paid FVC by Net One subject to Exhibit A. Returned
     inventory may include any Click to Meet software purchased from FVC and up
     to 37 Compaq servers and up to 37 each of the additional processor boards,
     memory boards and non-FVC software applications bundled with the servers.
     All components of Returned Inventory must be returned to FVC by October 3,
     2003

     The then-current representative of FVC Japan (Mr. Takayuki Kanda is
     designated by FVC on Amendment No.2 Effective Date) shall accept such
     return at Net One's offices in Japan. Net One agrees to provide storage
     space for Returned Inventory for up to ninety (90) days from Amendment No.2
     Effective Date at no charge to FVC. Thereafter Net One may dispose of the
     remaining FVC products of Returned Inventory at its own expense. If FVC
     solely determines that the server hardware requires to be returned to its
     California location, Net One agrees to pay the freight costs of such
     shipment.

Inventory Exchange

For the balance of Net One's FVC Product inventory not sold by Net One by the
time of Amendment No.2 Effective Date, excluding any remaining server hardware,
("REMAINING INVENTORY") Net One may either return or dispose at its own expense
such stock as previously outlined for full credit, with such credit applied to
new purchases of software licenses and software subscriptions from the current
FVC US Price List. Remaining Inventory returns will be valued at the price
originally paid by Net One. New products ordered in exchange for Remaining
Inventory returned product will be valued at current US list price, reduced by
the following discounts:

-  [***]
-  [***]

For the purpose of clarification, FVC shall provide support service for the new
products [***] NetOne.

This right of exchange for Remaining Inventory shall terminate on March 31,
2004.
