      B. Royalty. In addition to the License Fee, Licensee shall pay running
royalties for the license granted in Paragraph II.A. four times annually (as set
forth in Paragraph V) to Tessera during the term of this Agreement. Licensee
shall pay a starting royalty of [*] (US$[*]) per Billable Pin for TCC packages
made by Licensee hereunder, whether sold, transferred or used internally. After
Licensee has paid to Tessera [*] US DOLLARS (US$[*]) in royalties, the Licensee
shall begin paying a mid-range royalty of [*] (US$[*]) per Billable Pin for TCC
packages made by Licensee hereunder, whether sold, transferred or used
internally. After Licensee has paid to Tessera [*] US DOLLARS (US$[*]) in
cumulative royalties, Licensee shall begin paying a base royalty of [*] (US$[*])
per Billable Pin for TCC packages made by Licensee hereunder, whether sold,
transferred or used internally for the remainder of this Agreement.
Notwithstanding, no running royalty need be paid for scrap TCC packages for
which Licensee provides Tessera a certification from a third party customer that
such third party customer does not use, sell or otherwise transfer such scrap
TCC packages or receive payment or value of any kind therefor.

      C. Royalty Adjustments. In making the royalty payments due Tessera,
Licensee may subtract from such royalty payments any preceding royalty payments
for defective royalty bearing TCC packages that are returned to Licensee from
Licensee's customers ("Royalty Adjustment"). However, if at any time such
defective TCC packages are resold by Licensee, Licensee shall pay a royalty to
Tessera for such resold TCC packages, as set forth in this Agreement. Before a
Royalty Adjustment can be so subtracted, Licensee must have originally paid a
royalty on the particular returned TCC package. All Royalty Adjustments must be
specified with the information set forth in Attachment B hereto.

      D. Royalty Buy-Down Payment. At any time, Licensee may elect to pay
Tessera [*] US DOLLARS (US$[*]) in which event said Licensee shall notify
Tessera of Licensee's intent to exercise the option under this Paragraph and
tender such payment and henceforth pay royalties at the base royalty level of
[*] (US$[*]) per Billable Pin (as set forth in Paragraph III.B., above). Such
royalty buy-down payment shall not affect the royalties Licensee has paid to
Tessera prior to Licensee's exercise of the royalty buy-down payment set forth
in this Paragraph. Further, such royalty buy down payment shall also not affect
the royalty amounts due Tessera for TCC packages manufactured prior to
Licensee's exercise of the royalty buy-down payment set forth in this Paragraph.

      E. Consulting Fee and Deliverables. As consideration for the Consulting
Services, Licensee shall pay to Tessera a consulting fee in the sum of [*] US
DOLLARS (US$[*]) (hereinafter the "Consulting Fee"). The Consulting Fee shall be
paid to Tessera in progress payments for completion of tasks and services as
summarized in the table immediately below and further defined in Attachment D.
Notwithstanding anything herein to the contrary, Licensee agrees upon completion
of the relevant portion of the Deliverables (as set forth in the table below),
Tessera's Consulting Services' obligations with respect to such portions shall
terminate and Licensee shall tender any remaining, unpaid portion of the
Consulting Fee to Tessera with special dispatch. Licensee and Tessera agree to
coordinate all work with Licensee's project manager and engineers to accomplish
the following schedule of objectives:

taxes to the tax authorities in the Republic of Italy. Licensee shall promptly
furnish Tessera with the corresponding tax receipts evidencing payments thereof.
Tessera and Licensee recognize that the transactions contemplated hereunder may
qualify for withholding tax exemption or rebate under applicable Republic of

royalties due Tessera for the applicable payment period. All payments for fees
or royalties under this Agreement shall be made in US Dollars by wire transfer
to Union Bank of California, 99 Almaden Blvd., San Jose, CA 95113, Account Name:
Tessera, Account No.: 6450148359, Routing No. 122000496, International Swift

designate in writing. The payments of royalties and submission of such reports
from Licensee to Tessera under this Paragraph shall be made within forty-five
(45) days from the end of each quarter annual payment period and shall be
considered to be made as of the day on which such payments are received in
Tessera's designated bank account.

      VI. TECHNICAL TRANSFERS

      A. Tessera Training Services. In addition to granting of the aforesaid
licenses under the Tessera Patents and Technical Information, upon the Effective
Date of this Agreement and the payment of the License Fee described in Paragraph
III.A. above, Tessera will begin to transfer to Licensee the Technical
Information on a mutually agreeable schedule, including certain TCC package
assembly know-how, specifications and Standards for the TCC packages licensed
herein. However, it is understood and agreed by both parties that Licensee will
not require Technical Information transfer from Tessera in order to manufacture
Tape under this Agreement and Tessera shall not transfer such Tape information
to Licensee. For a period of up to twelve (12) months commencing with the
Effective Date of this Agreement, and according to a mutually agreeable time
schedule and manpower assignment schedule, Tessera will make certain of its
engineering staff available at its San Jose facilities for transfer activities,
including joint activities with Licensee's engineers, as may be necessary in
accordance with mutual agreement of the parties to successfully complete the
Technical Information transfer; however, Tessera shall not be obligated to
provide more than forty (40) working man days of engineering support during the
first twelve month period. Further, Licensee agrees that the number of actual
working man-days for any training in Tessera's clean room manufacturing assembly
line shall be multiplied by a factor of four (4) and applied against the
remaining training time due Licensee under this Paragraph. Licensee agrees to
pay all reasonable coach class air travel and hotel charges incurred by Tessera
personnel in connection with engineering support performed at any of Licensee's
facilities outside of San Jose. Additional engineering interactions, conducted
to collaborate on technical issues of mutual concern, shall be supported by each
party at its own expense. Additional engineering support (not to exceed forty
(40) working days) beyond the initial twelve month period for an additional
twelve (12) month period may be made available, according to a mutually
agreeable time schedule and manpower assignment schedule, at a per diem rate of
US $[*] per support engineer, plus reasonable air travel and hotel charges. Any
support or other services required thereafter may be provided upon terms
mutually agreeable to the parties. Notwithstanding the foregoing, Tessera is
under no obligation to transfer and/or license any information whether
confidential, proprietary or otherwise that it may be prohibited from
transferring to Licensee by contract with a third party or applicable law.

      VII. TCC IMPROVEMENT CROSS-LICENSE

      A. Tessera Improvements. Tessera will make available TCC package
improvements which have been reduced to practice including changes and
modifications in Standards, methods, materials and specifications relating to
TCC packages during the term of this Agreement. Notwithstanding the foregoing,
Tessera is under no obligation to transfer and/or license any information
whether confidential, proprietary or otherwise that it may be prohibited from

transferring to Licensee by contract with a third party or applicable law.
Notwithstanding any provision to the contrary, Tessera shall not be under any
obligation to transfer or disclose actual patent applications or related
documents to Licensee.

      B. Licensee Improvements. Licensee hereby grants to Tessera a world-wide,
fully-paid, non-exclusive, non-sublicensable, non-transferable, perpetual, right
to use Licensee Improvements and Licensee's Patents covering any inventions
contained in such Licensee Improvements to manufacture, have manufactured for
Tessera, use or sell TCC packages.

      C. Cross Licensing With Other Tessera Licensees. Licensee agrees to grant
to the other licensees of Tessera on commercially reasonable terms a
non-exclusive, non-transferable, non-sublicensable license under Licensee's
Patents covering any inventions contained in such Licensee Improvements that are
discoverable from an examination of the TCC packages made by Licensee unless
such other licensees refuse to grant to Licensee similar licenses under any of
such other licensees' patents relating to any improvements developed by such
other licensee on similar commercially reasonable terms. In no event shall
Licensee be under any obligation to grant such licenses to other licensees of
Tessera, unless Licensee Improvements are used in IC packages sold externally to
non-Affiliates or proposed by Licensee and adopted for incorporation into a TCC
packaging standard.

      D. Joint Improvements. Any improvement that is made through the joint
inventive efforts of Tessera and Licensee shall be deemed a "Joint Improvement"
hereunder and shall be the joint property of both Tessera and Licensee, and both
Tessera and Licensee shall have a fully-paid, non-assessable, transferable,
perpetual, sub-licensable right and license to use such Joint Improvements, but
such right and license shall not include any right of license by implication
with respect to any part of the Tessera Patents. Licensee and Tessera shall
reasonably consult with one another with respect to applying for and maintaining
jointly owned patents with respect to such Joint Improvements at shared expense.
In the event that one party hereto (the "Notifying Party") notifies the other
party that the Notifying Party wishes to apply for or maintain a patent in any
country for any such Joint Improvement and the other party hereto does not
confirm to the Notifying Party, within thirty (30) days thereafter, that such
other party will join in such patent application and share the cost thereof, the
Notifying Party shall have a right, at its own expense, to apply for or maintain
such patent in its own name, in which case such patent shall be the sole
property of the Notifying Party, and the Joint Invention in the country covered
by such patent shall be treated as an improvement made solely by the Notifying
Party, and shall be subject to the provisions of this Agreement covering such
party improvements. The parties hereto shall execute such documents and render
such assistance as may be appropriate to enable the party properly having title
to such improvements to maintain or obtain patents for the same.

      XI. REASONABLE AUDIT

      A. Financial Audit. Upon reasonable written prior notice, Tessera shall
have the right to examine and audit through an independent third party CPA firm,
not more frequently than once per year, all records of Licensee that may contain
information bearing upon the amount of fees payable under this Agreement;
provided, that the said auditor shall have agreed in advance in writing to

results of any such audit shall be final, and within thirty (30) days after
receiving the auditor's report, Licensee shall make payment to Tessera of any
amount which may be found to be payable, if any. Tessera shall bear the expenses
of such audit examinations unless royalties due and owing to Tessera are
determined by the auditor to be at least five percent (5%) greater than such
similar amounts as calculated and/or paid by Licensee, in which case Licensee
shall bear such expenses.

      B. Standards Audit. Prior to the first shipment of TCC packages to a third
party by Licensee upon which Licensee intends to bear the Marks under the
license set forth in Paragraph VIII.B. pursuant to this Agreement, Licensee
shall provide Tessera with sufficient quantities of such packages to enable
Tessera to determine if such packages are in compliance with the Standards
within a industry standard reasonable timeframe. Upon receipt of such packages,
Tessera shall promptly perform the tests set forth in Attachment C and provide a
written report to Licensee detailing the results of the tests so performed.
After the Licensee manufactured TCC packages have passed Tessera's testing
requirements, Licensee may use the Marks as set forth in Paragraph VIII. To
ensure the on-going, future minimum quality and reliability of the TCC packages
sold by Licensee under any of the Marks pursuant to this Agreement, Tessera
shall have a right to perform the tests set forth in Attachment C at any time
during the term of this Agreement upon 60 day written notice by Tessera to
Licensee of Tessera's intention to perform such Standards testing. Upon
Licensee's receipt of such written notice from Tessera, Licensee shall promptly

RELATED TO THE SUBJECT MATTER OF THIS AGREEMENT, EVEN IF THE PARTY HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES OR LOSSES.

      XIV. NON-DISCLOSURE

      A. Confidential Information Definition. "Confidential Information"
includes all information disclosed prior to the expiration or termination of
this Agreement by one party to another hereunder including, without limitation,
ideas, inventions (whether patentable or not), designs, product concepts,
improvements, manufacturing tolerances, quality standards, business strategies,
forecasts, customer lists, product development plans and marketing plans,
provided that such information is designated and marked as being confidential in
nature by the disclosing party at the time of disclosure to the receiving party
and provided further that such information, if disclosed orally, is reduced to
writing, marked as being confidential, and delivered to the receiving party
within thirty (30) days after such disclosure.

      B. Exclusions. Notwithstanding, Confidential Information shall not include
any information which: (1) was lawfully in possession prior to receipt from
disclosing party; (2) is or becomes a matter of public knowledge through no
fault of the receiving party; (3) is lawfully obtained by the receiving party
from a third party under no obligation of confidentiality; (4) is independently
invented by the receiving party without reference to the disclosed Confidential
Information; or (5) the receiving party receives prior written consent from the
disclosing party for disclosure of certain Confidential Information to a third
party.

      C. Standard of Care. The receiving party shall hold in confidence and
protect the disclosed Confidential Information by using the same degree of care
as they would use to protect their own Confidential Information, but no less
than a reasonable degree of care, to prevent unauthorized use, dissemination, or
publication of the Confidential Information. The parties hereto agree that there
is a duty to promptly advise the disclosing party of any unauthorized disclosure
or use of Confidential Information. The receiving party agrees the damages to
the disclosing party for improper disclosure of Confidential Information will

party and that therefore the disclosing party will be entitled to equitable
relief, including but not limited to injunctive relief. Notwithstanding, the
receiving party shall not be liable for any disclosure resulting from the sale
of any physical product or component; further, the receiving party may disclose
the other party's Confidential Information to the receiving party's Affiliates,
Suppliers or consultants where necessary for the manufacture, use or sale of
products by the receiving party so long as a suitable non-disclosure agreement
has been signed between such parties which has substantially similar terms as
this Paragraph XIV.

      D. Confidentiality Period. The parties agree that Confidential Information
shall be maintained in confidence by the receiving party for a period of five
(5) years from the date of first disclosure to the receiving party by the
disclosing party and shall not be used by the receiving party except in
furtherance of the rights and licenses granted pursuant to this Agreement.

      E. Early Termination & Return of Confidential Information. In the event
this Agreement is terminated for any reason and upon a request by a disclosing
party, the receiving party will promptly return or certify the destruction of
all Confidential Information it received from the disclosing party along with
all copies made by the receiving party. Upon such a request, the disclosing
party's Confidential Information contained on data storage media shall be
certified as being deleted therefrom.

      F. Promotional Materials. The parties hereto shall consult with each other
from time to time and mutually approve promotional materials, including samples,
technical data, or otherwise containing any proprietary and/or confidential
information of the parties, for disclosure to customers by either party or
jointly under a mutually agreeable and reciprocal non-disclosure agreement.

      G. Breach of Confidentiality. Breach of this Paragraph XIV by either party
shall be deemed sufficient cause for the other party to terminate any further
obligation to make confidential disclosures to the breaching party without
limiting any other remedy at law. If such a breach occurs, the non-breaching
party shall send a written notification to the breaching party. The breaching
party will then have thirty (30) days from the mailing date of the notification
within which to mitigate the effects of the wrongful disclosure amounting to a
breach hereunder. If such actions are sufficient to mitigate the effects of the
wrongful disclosure, the obligation of the non-breaching party to make
confidential disclosures shall resume.

      H. Employee Agreements. Both parties hereto represent that all of their
employees, including contract employees, shall have executed agreements
obligating such employees to assign ideas and inventions to their respective
employer prior to having access to Confidential Information received hereunder.

      I. Superceding Prior Confidentiality Terms. This supersedes all prior
written or oral understandings or agreements with respect to non-disclosure or
confidentiality issues.

of the Licensee Patents.

      E. Documentation Managers. Both Licensee and Tessera shall designate a
Documentation Manager to perform the task of logging and tracking the
confidential documents transferred between the companies. If possible, each
transfer of confidential information should be first transferred between the

parties, an effort should be made to send a copy of the disclosed information to
the receiving party's Documentation Manager along with the date of the
disclosure. Tessera's Documentation Manager is Christopher M. Pickett, Vice
President and General Counsel and may be contacted at the Tessera fax and street
address. Licensee's Documentation Manager is Enzo D'Antonio, President and may

unenforceable by a court having competent jurisdiction, it is mutually agreed
that this Agreement shall endure except for the part declared invalid or
unenforceable by order of such court. The parties shall consult and use their
reasonable efforts to agree upon a valid and enforceable provision which shall
be a reasonable substitute for such invalid or unenforceable provision in light
of the intent of this Agreement.

or for any delay in performance of any obligation under this Agreement caused by
circumstances beyond its reasonable control including, but not limited to, fire,
storm, flood, earthquake, explosion, war, labor disputes, acts of God, acts of
any national, state, or local government authority, and judicial action,
provided that the delayed party: (i) gives the other party written notice of
such cause promptly, and in any event within fifteen (15) days of discovery
thereof; and (ii) uses its reasonable efforts to correct such failure or delay
of its performance. If a party's performance is delayed under this Paragraph
more than sixty (60) days after the date when such performance was due, the
parties shall negotiate in good faith (i) to amend the delayed obligation to
accommodate the force majeure event, (ii) to delete the delayed obligation if
such deletion will not affect the validity or enforceability of the remainder of
this Agreement, provided such amendment or deletion complies with the intent of
the parties as stated herein, or (iii) to terminate this Agreement (as per
Paragraph X.B., above) upon the mutual agreement of the parties.
