Attachment A. If IGS discovers material non-conformance in conducting such
acceptance tests and provides RSS with sufficient written instructions,
equipment, machines and documentation ("Nonconformance Materials") to allow RSS
to readily reproduce the problems at its facility, RSS shall, at its cost, use
reasonable efforts to make corrections or develop workarounds within thirty (30)

and all individuals (employees, independent contractors, employees of
independent contractors, and any other individuals) who then have or have had,
at any time since IGS last provided such a list, access to the *** Technology.
IGS shall inform all persons who are given access to the *** Technology that the
*** Technology contains confidential trade secrets of RSS and is the

purpose of (i) confirming that it is protecting the *** Technology in accordance
with this Agreement, and (ii) reminding its employees and independent
contractors of the limited rights and obligations of IGS and each employee and
independent contractor pertaining to the *** Technology. Following each review,
IGS will notify RSS in writing that IGS conducted the review and (a) that no
violations were discovered, or (b) that violations were discovered, a
description of the nature and extent of the violations, and a description of the
actions taken by IGS to correct the violations. IGS shall take all actions
reasonably required to recover and prevent further use, reproduction and
disclosure of the *** Technology in the event of loss or misappropriation;
provided that if IGS fails to enforce any confidentiality obligations of its
employees or independent contractors or fails to recover and prevent further use
of the *** Technology, then RSS may take all necessary steps, including, without
limitation, initiating legal action, to enforce such agreements to protect its
interests in the *** Technology. IGS shall be fully responsible for the conduct
of all of its employees, independent contractors, agents and representatives who
may in any way breach this Section 9 or Section 16 below and shall indemnify RSS
for any damages relating to or arising from such breach.

     9.3  IGS expressly agrees to keep the *** Technology and Derivative Works
thereof and any portions or copies of the foregoing at IGS' offices located at

shall bear the expense of the audit. Each party may exercise its right to audit
no more than once per year unless an underpayment of over five percent (5%) has
been discovered in the prior audit. In such event, the underpaid party shall

     16.  Confidentiality.
          ---------------

          16.1  Each party ("disclosing party") may, from time to time, in
connection with performance under this Agreement, disclose confidential
information ("Confidential Information") to the other party ("receiving party").
Each recipient party agrees not to use (other than for purposes contemplated by
this Agreement), and will use reasonable efforts to prevent the disclosure to
third parties of, any of the disclosing party's Confidential Information that is
identified as confidential at the time of disclosure and is provided in tangible
form marked "confidential" or "proprietary" (or is reduced to such form within
thirty (30) days after oral disclosure). All RSS Software, Source Code, Verilog
Source Code and Derivative Works of any of the foregoing provided by RSS is
hereby identified and marked as RSS' Confidential Information. The IGS Chip, IGS
Software and Derivative Works provided by IGS are hereby identified as IGS'
Confidential Information. The recipient party's confidentiality obligation
hereunder shall not apply to information that the recipient party can document:

                (i)   was in the recipient party's possession or known by it
prior to receipt from the disclosing party;

                (ii)  is or (through no fault of the recipient party or any of
its employees, contractors, agents or licensees) becomes generally available to
the public;

                (iii) is rightfully disclosed to the recipient party by a third
party having no obligations of confidentiality to the disclosing party, provided
the recipient party complies with any restrictions imposed by the third party;

                (iv)  is independently developed by the recipient party without
use of or reference to the disclosing party's Confidential Information; or

                (v)   is required by law or regulation to be disclosed
(including, without limitation, in connection with SEC filings), provided that
the recipient party uses reasonable efforts to restrict disclosure and to obtain
confidential treatment therefor.

         16.2  Each recipient party acknowledges and agrees that due to the
unique nature of the disclosing party's Confidential Information, there can be
no adequate remedy at law for any breach of its obligations hereunder, that any
such breach may allow the recipient party or third parties to unfairly compete
with the disclosing party resulting in irreparable harm to the disclosing party
and, therefore, that upon any such breach or threat thereof, the disclosing
party shall be entitled to injunctive relief and other appropriate equitable
relief in addition to whatever remedies it may have at law, and to be
indemnified by the recipient party from any loss or harm (including, without
limitation, attorneys' fees) in connection with any breach or enforcement of the
recipient party's obligations hereunder or the unauthorized use or release of
any Confidential Information. The recipient party will notify the disclosing
party in writing immediately upon the occurrence of any such unauthorized
release or other breach of which it is aware.

terminates its business operations;

whether or not termination is effected, all other remedies will remain
available.

     18.  Export Requirements. IGS agrees to comply with the U.S. Foreign

     19.  Assignment. Neither this Agreement nor any rights, licenses or
          ----------
obligations hereunder, may be assigned by either party without the prior written
