     6.   CONFIDENTIAL INFORMATION

          6.1  Definition of Confidential Information.  SONY and LEXAR
               --------------------------------------
acknowledge that, in the course of performing their respective obligations
hereunder, each may obtain information relating to the other and the other's
products that is of a confidential and proprietary nature to such other party.
"Confidential Information" means confidential or proprietary information of
 ------------------------
either party which is (i) designated with the legend "Confidential" or
comparable legend in case of disclosure thereof in written, graphic, machine
readable or other tangible form or (ii) designated "Confidential" at the
disclosure thereof in other form and within thirty (30) calendar days after such
disclosure set forth in writing designated "Confidential" and forwarded to the
receiving party.  Confidential Information further includes without limitation
the existence and terms of this Agreement unless otherwise agreed in writing.

          6.2  Exclusions.  Confidential Information does not include
               ----------
information which (i) is or becomes public knowledge or is received by the other
party without the fault or action of the other party or any breach of any
confidentiality obligation; (ii) the other party can document was independently
developed by it without use or access to the Confidential Information; or (iii)
the other party can document was previously known to it prior to receipt of the
Confidential Information.

          6.3  Obligation.  Each of SONY and LEXAR agrees that for a period of
               ----------
ten (10) years after the receipt of such Confidential Information, it will (i)
use the other party's Confidential Information only in connection with
fulfilling its rights and obligations under this Agreement; (ii) hold the other
party's Confidential Information in strict confidence and exercise due care with
respect to its handling and protection, consistent with its own policies
concerning protection of its own Confidential Information of like importance but
in no instance less than reasonable care, such due care including without
limitation requiring its employees to execute non-disclosure agreements which
provide protection of the other party's Confidential Information which is at
least as protective as the terms and conditions of this Agreement; (iii) not
disclose, divulge or publish the other party's Confidential Information except
to such of its responsible directors, employees and consultants and legal and
financial advisors who have a bona fide need to know to the extent necessary to
fulfill such party's obligations under this Agreement or except to the extent
such Confidential Information is required to be disclosed pursuant to applicable
law, regulation or court order provided the other party uses reasonable efforts
to give the party owning the Confidential Information sufficient notice of such
required disclosure to allow the party owning the Confidential Information
reasonable opportunity to object to and to take legal action to prevent such
disclosure (or to request confidential treatment thereof); (iv) instruct all
such employees not to disclose the other party's Confidential Information to
third parties, without the prior written permission of the other party.  LEXAR
acknowledges and agrees that the "bona fide need to know" standard set forth in
the foregoing subsection (iii) above as applied to dissemination of SONY
Technology requires that authorized LEXAR employees must have actual need to use
the SONY Technology to design or develop a specific Licensed Memory Stick.
LEXAR further acknowledges and agrees that theoretical analysis and
investigation of (a) the features and functionality of the SONY Technology or
(b) potential application of the SONY Technology for an unidentified project
will not satisfy the "bona fide need to know" standard.  Each party may disclose
Confidential Information of the other party to its legal and financial advisors,
as necessary to obtain tax, legal and accounting advice.

     12.  GENERAL

          12.1  Governing Law.  This Agreement shall be governed by and
                -------------
construed in accordance with the laws of Japan without reference to the
conflicts of law principles thereof.

          12.2  Injunctive Relief.  Each of the parties acknowledges that
                -----------------
unauthorized disclosure or use of the other party's Confidential Information or
infringement or misappropriation of the other party's intellectual property
rights could cause irreparable harm and significant injury that would be
difficult to ascertain and may not be compensable by damages alone.
Accordingly, the parties agree that, in addition to any and all legal remedies,
each party shall be entitled to seek specific performance, injunction or other
appropriate equitable relief for claims regarding intellectual property rights
or Confidential Information.

          12.3  Assignment.  Neither party may assign or transfer this Agreement
                ----------
without the prior written consent of the other, except that each party may
assign or transfer this Agreement, and all rights and obligations hereunder, in
the course of a merger, reorganization or acquisition of all or substantially
all of such party's remaining assets without the consent of the other party.
Any assignment or transfer permitted hereunder will be subject to the written
assent of the assignee or transferee to assume all of the rights and obligations
associated with this Agreement.  Any attempted assignment in derogation of this
section will be null and void

          Notwithstanding LEXAR's right to assign or transfer this Agreement and
all rights and obligations hereunder, in the course of a merger, reorganization
or acquisition of all or substantially all of LEXAR's remaining assets without
the consent of SONY, LEXAR agrees not to assign or transfer this Agreement to *
or any entity that is controlled, directly or indirectly, by one or more of
such companies.

          12.4  Modification and Waiver.  No modification to this Agreement, nor
                -----------------------
any waiver of any rights, will be effective unless assented to in writing by the
party to be charged, and the waiver of any breach or default shall not
constitute a waiver of any other right hereunder or any subsequent breach or
default.

          12.5  Notices.  Any required or permitted notices hereunder must be
                -------
given in writing at the address of each party set forth below, or to such other
address as either party may substitute by written notice to the other in the
manner contemplated herein.  Notices will be effective on receipt.

          12.8  Headings.  The headings of the Sections of this Agreement are
                --------
for convenience only and will not be of any effect in construing the meanings of
the Sections.

          12.9  Counterparts.  This Agreement may be executed in multiple
                ------------

                -----------------------
under this Agreement, each of the parties will be operating as an independent

association, partnership, or joint venture between the parties hereto, or be
construed to evidence the intention of the parties to establish any such
relationship.  Neither party will have the power to bind the other party or
incur obligations on the other party's behalf without the other party's prior
written consent.

          12.11 Severability.  In the event that it is determined by a court of
                ------------
competent jurisdiction that any provision of this Agreement is invalid, illegal,
or otherwise unenforceable, such provision will be enforced as nearly as
possible in accordance with the stated intention of the parties, while the
remainder of this Agreement will remain in full force and effect and bind the
parties according to its terms.  To the extent any provision cannot be enforced
in accordance with the stated intentions of the parties, such provisions will be
deemed not to be a part of this Agreement.

          12.12 Entire Agreement.  This Agreement and the exhibits attached
                ----------------
hereto constitute the entire and exclusive agreement between the parties hereto
with respect to the subject matter hereof and supersede any prior
representations, understandings and agreements between the parties with respect

this Note, together with all accrued and unpaid interest, shall become
immediately due and payable prior to the specified due date of this Note upon
the occurrence of one or more of the following events:

              A.  the failure of the Maker to pay when due the accrued interest

outstanding voting stock) for consideration payable in cash or freely-tradable
securities, then the unpaid portion of the principal balance of this Note
attributable to any shares of the Corporation's common stock serving as
collateral for this Note which are vested at the time of such acquisition,
including any such shares which vest as a result of such acquisition, shall
become immediately due and payable upon the expiration of the ninety (90) period
following the effective of such acquisition; provided, however, that if the

(60)-day period immediately following the end of the applicable restriction

Corporation's common stock and payment of this Note shall be secured by a pledge
of those shares with the Corporation pursuant to the Stock Pledge Agreement to
be executed this date by the Maker. The Maker, however, shall remain personally
liable for payment of this Note and assets of the Maker, in addition to the
collateral under the Stock Pledge Agreement, may be applied to the satisfaction
of the Maker's obligations hereunder.

          8.  Collection.  If action is instituted to collect this Note, the
