                                  OEM AGREEMENT
                                (Cisco as Seller)

     This Amendment 3 to OEM Agreement (the "Agreement") is made as of the ____
of March, 2001 (the "Effective Date") by and between Cisco Systems, Inc., a
California corporation, having principal offices at 170 West Tasman Drive, San
Jose, California 95134-1706 ("Cisco") and Netro Corporation, a California
corporation having its principal place of business at 3860 North First Street,
San Jose, California 95134 ("Netro").

                                    RECITALS

     A.   Netro has been purchasing from Cisco the Cisco MGX 8220 shelves and
associated products, software and firmware pursuant to the OEM Agreement, dated
December 7, 1998, between Cisco and Netro (the "OEM Agreement"). The OEM
Agreement originally provided that Netro could purchase from Cisco the MGX 8220
shelves for a fifteen (15) month period or until Netro had purchased [***] units
of the MGX 8220 shelves.

     B.   The parties entered into Amendment One to the OEM Agreement in order
to extend the time period during which Netro could purchase the MGX 8220 shelves
and to increase the number of shelves that Netro could purchase

     C.   The parties entered into Amendment Two to the OEM Agreement in order
to extend the time period during which Netro could purchase the MGX 8220 shelves
and to increase the number of shelves that Netro could purchase

     D.   The parties now desire to enter into this Amendment in order to extend
further the time period during which Netro may purchase the MGX 8220 shelves..

     NOW, therefore, in consideration of the terms and conditions of this
Agreement, the parties agree as follows:

1.   DEFINITIONS

     1.1  Unless otherwise defined herein, all capitalized terms shall have the
meaning ascribed to them in the OEM Agreement.

2.   AMENDMENT TO PURCHASE AND SALE TERMS AND CONDITIONS

     2.1  Section 1.4 of the OEM Agreement is hereby amended by replacing the
words "fifteen months thereafter" with "June 30, 2002." The parties acknowledge
and agree that the intent of this replacement is to permit Netro to purchase
Products until June 30, 2002 instead of the fifteen (15) month period originally
set forth in the OEM Agreement or the extended period as set forth in Amendment
One to the OEM Agreement.

3.   TERM

          TERM. This Amendment shall commence as of the Effective Date and shall

terminate or expire upon termination or expiration of the OEM Agreement.

4.   NETRO'S SOFTWARE LICENSE OBLIGATIONS

     4.1 SOFTWARE LICENCE - THIRD PARTY LICENSES. Netro will continue to be
     solely responsible for obtaining any third party licenses required to
     develop, distribute and sell Netro's Board Products and Netro's Integrated

     event that Netro does not fulfill the foregoing obligation, Netro will
     indemnify, defend and hold Cisco harmless, at Netro's expense, from any
     action brought against Cisco to the extent it is based on a claim arising
     from the use or distribution of Wind River VX Works Software.
