        Re: First Amendment to Credit Agreement

Gentlemen:

        Reference is made to (a) the Credit Agreement dated as of September 20,
2000 (including all annexes, exhibits and schedules thereto, as the same may be
amended, restated, supplemented or otherwise modified from time to time, the
"Credit Agreement"), by and among Western Digital Corporation ("Borrower"), the
other credit parties party thereto, the lenders from time to time signatory
thereto ("Lenders"), General Electric Capital Corporation, as administrative
agent for Lenders (in such capacity, "Agent"), and Bank of America, N.A., as
documentation agent for Lenders ("Documentation Agent"; Agent and Documentation
Agent are collectively referred to as "Co-Agents" and each, a "Co-Agent") and
(b) the open items letter agreement dated September 20, 2000, as amended by the
Amendment to Open Items Letter dated as of October 19, 2000 (collectively, the
"Open Items Letter"). Capitalized terms or matters of construction defined or
established in Annex A to the Credit Agreement shall be applied herein as
defined or established therein.

        Connex intends to form a wholly owned Subsidiary named SANavigator,
Inc., a Delaware corporation ("SANavigator"). In connection with the formation
of SANavigator, Borrower has requested that Co-Agents and Lenders (a) consent to
the formation of SANavigator, (b) amend the definition of "Excluded Subsidiary"
in the Credit Agreement to include SANavigator, and (c) amend the Open Items
Letter, and Co-Agents and Lenders are willing to do so subject to the terms and
conditions of this First Amendment to Credit Agreement ("First Amendment").

        1. Ratification and Incorporation of Credit Agreement. Except as
expressly modified under this First Amendment, (a) each Credit Party hereby
acknowledges, confirms, and ratifies all of the terms and conditions set forth
in, and all of its obligations under, the Credit Agreement, and (b) all of the
terms and conditions set forth in the Credit Agreement are incorporated herein
by this reference as if set forth in full herein.

        2. Consent under Credit Agreement. Pursuant to Section 6.1 of the Credit
Agreement, Borrower is prohibited from forming or acquiring or permitting any of
its Subsidiaries from forming or acquiring, any Subsidiary (with certain
exceptions) unless Co-Agents and Requisite

Lenders have given their prior written consent thereto. At the request of
Borrower, Co-Agents and Requisite Lenders hereby consent to the formation by
Connex of SANavigator.

        3. Amendment to Credit Agreement. The definition of "Excluded
Subsidiary" in Annex A of the Credit Agreement is hereby deleted in its entirety
and the following is substituted therefor:

        "Excluded Subsidiaries" shall mean Connex, SageTree, Pacifica, Cameo
        Technologies, Inc, a Delaware corporation formerly known as WDC.NET,
        Inc., Keen Personal Media, Inc., a Delaware corporation, Keen Personal
        Technologies, Inc., a Delaware corporation, SANavigator, Inc., a
        Delaware corporation, and Targets that become "Excluded Subsidiaries" in
        accordance with the provisions of Section 6.1.

        4. Extension of Deadline for Certain Open Items. At Borrowers' request,
Agent agrees to extend the deadline for the occurrence of the Corporation
Reorganization under and as defined in the Open Items Letter. Paragraph 10 of
the Open Items Letter is deleted in its entirety and the following is
substituted therefor:

        10. If the Corporate Reorganization has not occurred on or before May
        31, 2001, then (a) the Loan Documents shall be amended to exclude Intera
        Systems, Inc., a California corporation ("Intera"), and Aristos Logic
        Corporation, a California corporation ("Aristos"), as Excluded
        Investments, and (b) Borrower shall pledge its current interests in
        Intera and Aristos to Agent, for the benefit of Agent and Lenders, in
        whatever form such interests are in as of May 31, 2001, and deliver to
        Agent, for the benefit of Agent and Lenders, such current interests
        accompanied by duly executed instruments of transfer or assignment in
        blank in accordance with the terms of the Pledge Agreement and shall
        constitute "Pledged Collateral" thereunder; provided, that prior to May
        31, 2001, Borrower shall have no duty whatsoever to preserve the Intera
        or Aristos investments and may deal with such investments in its sole
        discretion.

If Borrower fails to comply with the provisions of Paragraph 10 of the Open
Items Letter, then such failure shall constitute an Event of Default under the
Credit Agreement.

        5. Conditions to Effectiveness. The effectiveness of this First
Amendment is subject to satisfaction of each of the following conditions
precedent:

            (a) receipt by Co-Agents of a copy of this First Amendment duly
executed by Borrower, each of the other Credit Parties, Co-Agents and Requisite
Lenders;

            (b) receipt by Co-Agents of a copy of the Second Amendment to
Patent, Trademark and Copyright Security Agreement executed by Borrower,
Co-Agents and Lenders; and

            (c) the absence of any Defaults or Events of Default.

other Credit Party has previously advised Co-Agents in writing as contemplated
under the Credit Agreement, are true and correct in all material respects as of
the date hereof. This First Amendment has been duly executed and delivered by
each Credit Party and constitutes a legal, valid and binding Obligation of such
Person, enforceable against such Person in accordance with its terms.

        8. Miscellaneous.

shall be effective as delivery of a manually executed counterpart thereof.

            (b) Headings. Section headings used herein are for convenience of

construed and enforced in accordance with, the laws of the State of California
applicable to contracts made and performed in such state, without regard to the
principles thereof regarding conflict of laws.

            (d) Effect. Upon the effectiveness of this First Amendment, from and

Agreement," "hereunder," "hereof" or words of like import shall mean and be a

            (e) No Novation. Except as expressly provided in Sections 2, 3 and 4
of this First Amendment, the execution, delivery, and effectiveness of this
First Amendment shall not (i) limit, impair, constitute a waiver of, or
otherwise affect any right, power, or remedy of Co-Agents and Lenders under the
Credit Agreement or any other Loan Document, (ii) constitute a waiver of any
provision in the Credit Agreement or in any of the other Loan Documents, or
(iii) alter, modify, amend, or in any way affect any of the terms, conditions,

contained in the Credit Agreement, all of which are ratified and affirmed in all
respects and shall continue in full force and effect.

            (f) Conflict of Terms. In the event of any inconsistency between the
