Netherlands, and Nokia Corporation, a corporation incorporated under the laws of
the Republic of Finland, with respect to shares of common stock, par value
$0.0001 per share, of Redback Networks Inc., a Delaware corporation (the
"Company").

                  Capitalized terms used herein and not defined herein have the
meanings ascribed thereto in the Schedule 13D. Except as indicated herein, the
information set forth in the Schedule 13D remains unchanged.

Item 2. Identity and Background.

                  Schedule 1 of the Schedule 13D is amended and restated in its
entirety to read as the Schedule 1 attached to this Amendment No. 1 and is
incorporated herein by reference.

Item 4. Purpose of Transaction

                  The second to last paragraph of Item 4 of the Schedule 13D is
amended by adding the following at the end thereof:

                  On August 5, 2003, the Company and NFI executed Amendment
         Number One to Common Stock Purchase Warrant (the "Warrant Amendment"),
         pursuant to which the Warrant terminated effective as of August 1,
         2003. The description of the Warrant Amendment is qualified entirely by
         reference to the Warrant Amendment, a copy of which is incorporated
         herein by reference at Exhibit E.

                  The last paragraph of Item 4 of the Schedule 13D is amended
and restated in its entirety to read as follows:

                  Mr. Lehtoranta did not stand for re-election to the Company
         Board at the Annual Meeting of Stockholders of the Company held on May
         7, 2003. Since May 7, 2003, none of NFI or its affiliates has had a
         representative on the Company Board.

                    Except as set forth herein or in connection with voting the
          shares of Common Stock that they may own in respect of the
          transactions proposed by the Company described in the Form S-4
          Registration Statement filed by the Company with the SEC on August 6,
          2003 (as such may be amended), at the present time the Reporting
          Persons have no plans or proposals which relate to or would result in
          (a) the acquisition by any person of additional securities of the
          Company, or the disposition of securities of the Company, (b) an
          extraordinary corporate transaction, such as a merger, reorganization
          or liquidation, involving the Company or any of its subsidiaries, (c)
          a sale or transfer of a material amount of assets of the Company or
          any of its subsidiaries, (d) any change in the present board of
          directors or management of the Company, including any plans or
          proposals to change the number or term of directors or to fill any
          existing vacancies on the board, (e) any material change in the
          present capitalization or dividend policy of the Company, (f) any
          other

         material change in the Company's business or corporate structure, (g)
         changes in the Company's charter, bylaws or instruments corresponding
         thereto or other actions which may impede the acquisition of control of
         the Company by any person, (h) a class of securities of the issuer to
         be delisted from a national securities exchange or to cease to be
         authorized to be quoted in an inter-dealer quotation system of a
         registered national securities association, (i) a class of equity
         securities of the Company becoming eligible for termination of
         registration pursuant to Section 12(g)(4) of the Exchange Act or (j)
         any action similar to any of those enumerated above.

                    Each Reporting Person expects to evaluate its investment in
          the Company on an ongoing basis based on the Company's financial
          condition, business operations and prospects, market price of the
          Common Stock, conditions in securities markets generally, general
          economic and industry conditions and other factors. Accordingly, each
          Reporting Person reserves the right to change its plans and intentions
          at any time, as it deems appropriate. In particular, each Reporting
          Person may, at any time and from time to time, and NFI currently
          expects that it may, dispose of more shares of Common Stock and/or
          enter into privately negotiated derivative transactions with
          institutional counterparties to hedge the market risk of some or all
          of its positions in the Common Stock, or each Reporting Person may, at
          any time and from time to time, acquire additional Common Stock or
          securities convertible or exchangeable for Common Stock. Any such
          transactions may be effected at any time and from time to time,
          subject to any applicable limitations of the Securities Act of 1933,
          as amended (the "Securities Act"). To the knowledge of each Reporting
          Person, each of the persons listed on Schedule 1 hereto may make the
          same evaluation and reserves the same rights.
