     5.  RECORDS AND AUDIT REQUIREMENTS

          5.1  Records.  For a period of three (3) years after the later date
               -------
that each royalty or other payment is due or is made under this Agreement,
Samsung will make and maintain such books, records and accounts as are
reasonably necessary to verify such royalty and other payments.

          5.2  Reports.  Within sixty (60) calendar days after the end of each
               -------
calendar half, or in the case of Section 4.3, within sixty (60) calendar days
after the end of each annual IDC publication, until all royalties and other
payments payable hereunder shall have been reported and paid, Samsung shall

period.  If no royalties are due, that fact shall be shown on such statement.

          5.3  Audit.  Upon at least thirty (30) calendar days prior written

and approved by the other, which approval will not be unreasonably withheld, to
audit the other's books, records, and accounts, and other relevant information
for the purpose of (i) verifying royalties and other payments reported under
Section 5.2, and (ii) verifying Lexar Sales Ceiling under Section 4.3. If such
accounting firm concludes that additional amounts were owed to Lexar during the
audited period, Samsung shall pay such additional amounts within thirty (30)
calendar days of the date Lexar delivers to Samsung such accounting firm's
written report so concluding. The fees charged by such accounting firm shall be
paid by the party authorizing the audit; provided, however, if the audit
discloses that the royalties payable by Samsung for such period are more than
one hundred fifteen percent (115%) of the amounts actually paid for such period,
then Samsung shall pay the reasonable fees and expenses charged by such
accounting firm.

     6.  CONFIDENTIAL INFORMATION

         6.1  Definition of Confidential Information.  Lexar and Samsung
              --------------------------------------
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.

         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 Samsung and Lexar agrees that, during the
              ----------
term of this Agreement and for a period of five (5) years thereafter, 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

                                       8
<PAGE>

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); and (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. Samsung 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 Technology requires that authorized Samsung employees
must have actual need to use the Lexar Technology to design or develop a
specific Licensed Lexar Product. Samsung 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: (i) to its
legal and financial advisors, as necessary to obtain tax, legal and accounting
advice; (ii) in connection with SEC filings; and (iii) to bona fide potential
investors or acquirers in connection with a financing, merger, acquisition or
similar transaction, provided that investors or acquirers are subject to,
confidentiality obligations at least as restrictive as those contained herein.
