that Sony shall only be licensed under LEXAR Intellectual Property * Licensed
Memory Stick. Further, the license to offer to sell and sell Improved Memory
Stick controllers apart from the Improved Memory Sticks is limited to sales and
offers to sell such controllers to parties that have a license from LEXAR to
manufacture Improved Memory Sticks from such controllers; provided, however,
SONY shall be permitted to offer for sell and sell controllers any party as
repair or replacement parts for Licensed Memory Stick.

               SONY's sublicense rights under this Section 2.2(b) shall be
contingent upon SONY entering into a written agreement with each sublicensee in
the form of Exhibit C. SONY will provide LEXAR with a copy of each such

negotiate in good faith additional specific provisions to the form sublicensee
agreement to sufficiently protect LEXAR's Confidential Information. LEXAR and
SONY acknowledge that in the course of these negotiations, the parties' mutual
interest in making the Host Device manufacturing license available as broadly as
possible should be weighed against the importance of protecting LEXAR's
Confidential Information.

               Sublicensees under this Section 2.2 shall not have the right to
sublicense the rights granted under this agreement.

     6.   CONFIDENTIAL INFORMATION

          6.1  Definition of Confidential Information.  LEXAR and SONY
               --------------------------------------
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 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.  SONY
acknowledges and agrees that the "bona fide need to know" standard set forth in
the foregoing subsection (iii) above as applied to dissemination of LEXAR
<PAGE>

Technology requires that authorized SONY employees must have actual need to use
the LEXAR Technology to design or develop a specific Licensed Memory Stick. SONY
further acknowledges and agrees that theoretical analysis and investigation of
(a) the features and functionality of the LEXAR Technology or (b) potential
application of the LEXAR 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.

     7.   INTELLECTUAL PROPERTY RIGHTS

          7.1  LEXAR Technology.  All right, title, and interest in and to the

     8.   USE OF CONTRACTORS

     Each party may retain third parties ("Contractors") to furnish services to
it in connection with the performance of this Agreement and permit such
Contractors to have access to the other party's Confidential Information, but
only to the extent and insofar as reasonably required in connection with such
party's performance under this Agreement; provided that all such Contractors
shall be required to execute a written agreement sufficient to secure compliance
by the Contractors with the contracting party's obligations of confidentiality
concerning Confidential Information set forth in this Agreement.

its Associated Companies will take all necessary measures and precautions,
including, but not limited to, measures requiring their present and future
employees to give suitable undertakings of secrecy both for the period of their
