          Sublicenses pursuant to Section 2.1 shall terminate.

               (f) Except as otherwise expressly provided below, each Sublicense
          shall, by its terms, terminate upon termination of this Agreement for
          any reason. A Sublicense in force at the time of termination of this
          Agreement may continue in effect thereafter if:

                    (i) TST has either approved in writing all of the terms and
               conditions of such Sublicense in advance or has exercised an
               option, provided to it in such Sublicense, either to terminate or
               to continue such Sublicense, in which case TST shall succeed to
               all rights and ownership interests of MSC and shall assume all
               ongoing obligations and liabilities thereunder that accrue
               following termination of this Agreement and that would otherwise
               be the responsibility of MSC; or

                    (ii) the terms and conditions of such Sublicense expressly
               provide that it will continue in effect following termination of
               this Agreement and TST has not either (a) approved such
               Sublicense in writing in advance, or (b) elected to continue
               under the Sublicense terms, in which case TST shall succeed to
               all of the rights and ownership interests of MSC under such
               Sublicense, but TST shall not succeed to any liabilities or
               obligations of MSC under such Sublicense and MSC shall continue
               to be solely responsible with respect to all of its liabilities
               and obligations thereunder.

     2.6  On or prior to October 14, 2002, TST shall furnish to MSC a listing of
all patents and patent applications issued or filed by or on behalf of TST on or
prior to September 30, 2002, including with such listing a complete file of any
and all pending patent applications. Such patents and patent applications shall
be considered as part of the Licensed Patents and Schedule 2 attached hereto
shall be updated accordingly.

     2.7  On or prior to March 1, 2006 and each succeeding anniversary of such
date thereafter so long as the licenses granted hereunder continue to be
exclusive, MSC shall notify TST in writing if MSC desires that such licenses
continue to be exclusive and agrees to continue to pay Minimum Annual Royalties
pursuant to Section 3.5, which payment is a condition of continued exclusivity.
If at any time MSC fails to give timely notice as set forth above or defaults
with respect to payments of Minimum Annual Royalties in accordance with Section
3.5, upon three (3) business days prior written notice to MSC from TST, and
MSC's failure to cure such delinquent notice or default within the three (3)
business day period, TST in addition to all other remedies available to it
hereunder may terminate the exclusivity provisions of this Agreement, after
which MSC's licenses hereunder shall be non-exclusive.

     2.8  Should the rights and licenses of MSC hereunder become non-exclusive
for any reason, then the Manufacturing Sublicenses, if any, in effect at that
time shall continue in effect

                                       7

                                     Confidential information redacted and filed
                                                 separately with the Commission.

and MSC shall be entitled to continue to grant new Manufacturing Sublicenses. In
such event, TST shall be entitled to increase the price at which it will supply
Chips for such new Manufacturing Sublicenses to TST's cost, as determined
pursuant to Section 13.5, divided by [***]. TST shall continue to supply Chips
for preexisting Manufacturing Sublicenses at its cost as determined pursuant to
Article XIII. TST agrees that, so long as MSC continues to purchase Chips from
TST for use by sublicensees under Manufacturing Sublicenses granted during the
exclusivity period, TST will not sell or offer to sell Chips to such
sublicensees for use in connection with such pre-existing Manufacturing
Sublicenses, either directly or indirectly through some other licensee. MSC
shall be responsible for providing support to all sublicensees under
Manufacturing Sublicenses.

     2.9  Should the rights and licenses of MSC hereunder become non-exclusive
for any reason, then the Full Sublicenses in force at that time shall continue
in effect and TST agrees that, so long as such Full Sublicenses remain in force
during the term of this Agreement, TST shall not directly or indirectly through
another licensee seek to license such pre-existing sublicensees with respect to
all or any of the rights granted to them in such pre-existing Full Sublicenses.
MSC shall be responsible for providing support to sublicensees under such
preexisting Full Sublicenses. TST shall continue to supply Chips for preexisting
Full Sublicenses at its cost as determined pursuant to Article XIII.

                             ARTICLE III - ROYALTIES

     3.1  MSC, as herein provided, shall pay Total Royalties to TST. Total
Royalties shall consist of the following components:

          (a)  Running Royalties based upon Net Sales of Licensed Products by
               MSC and its Affiliates (Section 3.2), and

          (b)  Fees based upon Full Sublicense Profits (Section 3.3), and

          (c)  Fees based upon Manufacturing Sublicense Profits (Section 3.3).

     3.2  Royalties based on Net Sales of Licensed Products shall be defined as
"Running Royalties" and shall be computed by multiplying Net Sales of Licensed
Products times the Base Royalty Rate. Running Royalties shall be based upon (i.)
each Licensed Product, any portion of which or the manufacture, sale, or use of
which is covered by Licensed Patents in the country of manufacture; and (ii.)
each Licensed Product, any portion of which and the manufacture, sale, or use of
which is covered by Licensed Patents in the country of use or sale, unless
royalties have been paid by MSC thereon pursuant to Article 3.2 (i.) hereof.
"Base Royalty Rate" is defined, with respect to various levels of Net Sales in
each Fiscal Year, as the applicable rate set forth in the following table:

                                       8

                                     Confidential information redacted and filed
                                                 separately with the Commission.

     Base Royalty Rate                      Net Sales During Fiscal Year
     -----------------                      ----------------------------
          [***].                                      [***].

          In the event that Licensed Products are sold in the form of
Combination Products, Net Sales for the purpose of determining Running Royalties
on such Combination Products shall be calculated by multiplying actual Net Sales
of such Combination Products by the fraction A/(A+B) where "A" is the invoice
price of the Licensed Products if sold separately by MSC, and "B" is the total
invoice price of any other product or products in the combination, if sold
separately by MSC or an Affiliate. If, on a country-by-country basis, the
Licensed Products are not sold separately, "A" shall be the invoice price
charged for similar products sold in the Field by MSC or an Affiliate and "B"
shall be the invoice price of the other product or products sold in the Field by
MSC or an Affiliate.

     If on a country-by-country basis the other product or products in the
combination are not sold separately in said country by MSC or an Affiliate, Net
Sales, for the purpose of determining Running Royalties on the Combination
Products shall be calculated by multiplying actual Net Sales of such Combination
Products by the fraction A/C, where "A" is the invoice price of the Licensed
Products if sold separately by MSC or an Affiliate, and "C" is the invoice price
of the Combination Product by MSC or an Affiliate.

     If on a country-by-country basis neither the Licensed Products nor the
other product or products in the Combination Product is sold separately in said
country by MSC or an Affiliate, Net Sales, for purposes of determining Royalties
Royalties on the Combination Products, shall be calculated as if the Licensed
Products and other product or products in the combination had been sold in the
United States by MSC so that the fraction A/(A+B), as defined above, shall be
multiplied by the actual Net Sales of the Combination Product in such country to
determine Net Sales for calculation of the royalty.

     3.3  MSC shall pay to TST fees equal to [***] of the Full Sublicense
Profits and fees equal to [***] of the Manufacturing Sublicense Profits.

     3.4  Total Royalties shall accrue to TST on the dates that Net Sales, Full
Sublicense Profits and/or Manufacturing Sublicense Profits are recognized by MSC
or its Affiliates in accordance with GAAP.

     3.5  MSC agrees to pay to TST minimum annual royalties ("Minimum Annual
Royalties") for each Fiscal Year as provided below. Minimum Annual Royalties
shall be fully creditable against Total Royalties accruing during the Fiscal
Year for which such Minimum

                                       9

                                     Confidential information redacted and filed
                                                 separately with the Commission.

Annual Royalties are paid. Minimum Annual Royalties shall be paid in lieu of any
obligation of MSC to use best efforts or any standard of efforts to promote and
sell Licensed Products.

                         Minimum Annual Royalty Schedule
                         --------------------------------

             MSC Fiscal Year Ending         Minimum Annual Royalty
             ----------------------         ----------------------
                  2003                         $1,000,000.00
                  2004                         $1,500,000.00
                  2005                         $2,750,000.00
                  2006                         $2,750,000.00
                  [***]                        [***]

     In the event MSC elects to grant a Sublicense with respect to [***] in
Licensed Products, the Minimum Annual Royalty set forth in the foregoing table
shall be increased by an additional [***] for each Fiscal Year or portion
thereof (on a prorated basis for the remainder of such Fiscal Year) during which
such Sublicense is in effect.

     3.6  All amounts due under this Agreement shall be paid in United States
dollars by wire transfer to the account designated from time to time by TST for
such purposes in written notice given in accordance with Section 8.9 and shall
be deemed made at the office of the financial institution where such account is
held. In the event that TST at any time fails to designate an active account for
such purposes, such payments shall be made by check delivered to TST's offices.

     The United States dollar amounts due in payment of Total Royalties shall be
determined by first converting any Net Sales, Manufacturing Sublicense Profits,
and Full Sublicense Profits denominated in the currency of another country to
equivalent United States dollars and then applying (1) the applicable Base
Royalty Rate in Section 3.2 to the converted worldwide Net Sales, and (2) the
applicable rates provided in Section 3.3 to the Manufacturing Sublicense Profits
and the Full Sublicense Profits, respectively. The conversion rate used for each
such currency conversion shall be the average rate of exchange quoted by the
Wall Street Journal, New York Edition, for the relevant currency during the
Fiscal Quarter in which the Net Sales or the revenues giving rise to
Manufacturing Sublicense Profits and/or Full Sublicense Profits occurred.

     3.7  Payments shall be made to TST as follows:

          (a)  During the initial MSC exclusive license period (the four years
               ending February 28, 2006), MSC shall make quarterly payments to
               TST on June 1st, September 1st, December 1st and March 1st (or
               the first business day thereafter) equal to 25% of the Minimum
               Annual Royalty due for the applicable Fiscal Year pursuant to
               Section 3.5.

               By the 45th day after the end of each Fiscal Quarter, MSC shall
               provide to TST a report in accordance with the requirements of
               Section 3.8 that shall

                                       10

                                     Confidential information redacted and filed
                                                 separately with the Commission.

<PAGE>

               reflect the Total Royalties accrued during the Fiscal Quarter and
               the Fiscal Year to date period.

               If Total Royalties accrued exceed Minimum Annual Royalties paid
               for Fiscal Years ending February 28/29, 2003, 2004, 2005 or 2006,
               then such additional Total Royalties shall be paid to TST by the
               45th day following the last day of the Fiscal Year then ended.

          (b)  While MSC's license is exclusive for Fiscal Years ending after
               February 28, 2006, MSC shall make quarterly payments to TST on
               June 1st, September 1st, December 1st and March 1st (or the first
               business day thereafter) equal to 25% of the Minimum Annual
               Royalty due for the applicable Fiscal Year pursuant to Section
               3.5.

               By the 45th day after the end of each Fiscal Quarter ending after
               February 28, 2006, MSC shall provide to TST a report in
               accordance with the requirements of Section 3.8 that shall
               reflect the Total Royalties accrued during the Fiscal Quarter and
               the Fiscal Year to date period. With such report each quarter,
               MSC shall pay to TST an amount equal to the greater of (i) the
               then unpaid balance of the Total Royalties accrued for the Fiscal
               Year to date period or (ii) the then unpaid balance of the
               Minimum Annual Royalty amounts accrued for the Fiscal Year to
               date period.

          (c)  In the event that MSC's license is non-exclusive, by the 45th day
               after the end of each Fiscal Quarter, MSC shall provide to TST a
               report in accordance with the requirements of Section 3.8 that
               shall reflect the Total Royalties accrued during the Fiscal
               Quarter and the Fiscal Year to date period. With such report each
               quarter, MSC shall pay to TST the Total Royalties accrued during
               the Fiscal Quarter.

     3.8  Within 45 days following the end of each Fiscal Quarter, MSC shall
provide TST with a report written in English and certified by the Chief
Financial Officer of MSC, setting forth the Total Royalties due and payable
during the Fiscal Quarter and the Fiscal Year to date period as of the end of
such Fiscal Quarter. Such report shall be in sufficient detail as mutually
agreed by MSC and TST, and shall include breakdowns of Net Sales of Licensed
Products, Manufacturing Sublicense Profits (by sublicensee), and Full Sublicense
Profits (by sublicensee) between the transportation and consumer electronics
markets.

     3.9  The timely payment of Total Royalties and of Minimum Annual Royalties
is a material obligation. If MSC fails to make such payments when due, TST shall
have the right to terminate this Agreement pursuant to Section 10.4(a).

     3.10 Notwithstanding the foregoing, the first payment of Total Royalties
due under this Agreement shall not occur until June 1, 2002 and the period from
the Effective Date to the last

                                       11

                                     Confidential information redacted and filed
                                                 separately with the Commission.

<PAGE>

day of the Fiscal Quarter ending immediately prior to the foregoing date shall
be deemed the first reporting period for purposes of Section 3.7 (a).

     3.11 MSC shall accrue in favor of TST as of February 28, 2002, $166,666.66
for the period January 1, 2002 through February 28, 2002, such accrual to be
paid to TST with the payment due June 1, 2002.

                           ARTICLE IV - RECORDKEEPING

     4.1  MSC shall keep accurate records that are sufficiently detailed and
complete to permit an examination by TST pursuant to Section 4.2 for purposes of
verifying all information required to be reported or determined pursuant to
Articles III and XV hereof. Such records for each Fiscal Year shall be
maintained for at least three (3) full years following MSC's filing of its
corresponding Annual Report on Form 10-K with the Securities and Exchange
Commission, provided that, for purposes of Article XV MSC may not claim losses
for periods in which records are no longer maintained as a part of the
cumulative losses unless MSC has theretofore provided TST with detailed reports
of such losses and afforded TST an opportunity to examine the relevant records
at MSC's expense.

     4.2  TST shall have the right, at its sole discretion and expense, upon
written notice given within sixty (60) days following the later of (i) its
receipt of the report for fourth Fiscal Quarter of each Fiscal Year or (ii)
April 30 following the end of such Reporting Period to nominate an independent
accountant reasonably acceptable to and approved by MSC, such acceptance and
approval not to be unreasonably withheld, conditioned or delayed, who shall have
access to MSC's records (after executing a confidentiality agreement reasonably
acceptable to MSC) during reasonable business hours for the purpose of
inspecting and examining such records and verifying the amounts payable by MSC
as required under this Agreement for the immediately preceding Fiscal Year, such
examination to be completed no later than August 31 of the respective calendar
year. The accountant shall disclose to TST only information relating solely to
the accuracy and completeness of the reports and the correct amounts paid and
payable under this Agreement. A copy of the Accountant's examination report
shall be delivered to MSC. Should MSC fail to file its Form 10-K report with the
Securities and Exchange Commission by May 31 of any year, and then the date by
which TST shall give notice of its intent to examination will be extended for a
period equal to the number of business days that such filing is delayed. In
addition, if an examination reveals a deficiency in MSC payments that equals or
exceeds the criteria set forth in Section 4.4, then TST may elect to have the
approved accountant inspect and examine records relating to any of the last
three preceding Fiscal Years as to which no previous examination has been
conducted.

     4.3  If TST's examination or inspection determines that the amounts due
from MSC hereunder were greater than the amounts reported and paid by MSC, TST
shall promptly furnish to MSC a copy of the accountant's examination report
setting forth the amount of the deficiency, and showing, in reasonable detail,
the basis upon which the deficiency was determined. Subject to Article IX, MSC
shall remit to TST a sum equal to the deficiency plus compound interest

                                       12

                                     Confidential information redacted and filed

<PAGE>

thereon computed at the prime rate as reported in the New York Edition of the
Wall Street Journal for the last business day of the Reporting Period plus two
percent (2%) within thirty-days (30) from the date of delivery of the
examination report. Should the examination report disclose that MSC has made an
overpayment, then, within thirty (30) days thereof, TST shall return to MSC the
amount of the overpayment plus compound interest thereon computed at the prime
rate as reported in the New York Edition of the Wall Street Journal for the last
business day of the Reporting Period plus two percent (2%).

     4.4  All costs of any independent examination shall be borne by TST.
However, MSC shall reimburse TST for all actual out-of-pocket costs of the
independent examination if the independent examination reveals underpayments in
excess of (i) five percent (5%) of the amount originally reported by MSC to be
due for the examined Reporting Periods and (ii) one hundred thousand dollars
($100,000.00), whichever is greater.

     4.5  Any tax required to be withheld on monies payable to TST under the
laws of any country shall be deducted from the amounts paid to TST by MSC and
shall be promptly paid by MSC for and on behalf of TST to the appropriate
governmental authority, and MSC shall furnish TST with proof of payment of such
tax.

                      ARTICLE V - PATENTS AND IMPROVEMENTS

     5.1  In the event TST decides to abandon or discontinue prosecution or
maintenance of any patent or patent application listed on Schedule 2, TST shall
exert commercially reasonable efforts to provide MSC with sufficient notice to
allow MSC to continue prosecution or to maintain the affected patent application
or patent, provided that any continued prosecution of a pending patent
application does not result in the disclosure of information maintained by TST
as a trade secret.

     5.2  Pursuant to paragraph 5.1, MSC shall have the option, exercisable upon
written notification to TST, to assume full responsibility for the prosecution
or maintenance of the affected patent(s) or patent application(s), in which
event all such affected patent(s) and patent application(s) shall be promptly
assigned by TST to MSC, who thereafter for all purposes shall be deemed the
owner of all right, title, and interest in such patent(s) or patent
application(s) subject only to a perpetual, paid-up, worldwide license
thereunder in favor of TST and to any other pre-existing licenses theretofore
granted by TST to third parties, in each case for activities outside the Field.
In no event shall MSC be liable for or subject to any obligations of TST under
any such third party licenses. Should MSC exercise the option herein granted,
then TST shall assist MSC in effecting the assignment (including signing all
such papers as MSC shall reasonably deem necessary) at no additional costs to
MSC other than reimbursement of TST's reasonable out-of-pocket expenses incurred
in connection therewith.

     5.3  During the period commencing October 1, 2002 and, unless earlier
terminated as provided below, continuing during the term of this Agreement (the
"Joint Development Period"), MSC and TST will cooperate in developing and
commercializing Improvements. All

                                     Confidential information redacted and filed
                                                 separately with the Commission.

<PAGE>

Improvements invented, conceived or acquired by or on behalf of either or both
MSC and TST, either independently or jointly, during the Joint Development
Period shall be jointly and equally owned by MSC and TST, subject only to the
restrictions and limitations set forth in this Section 5.3. Either MSC or TST
may elect to terminate the Joint Development Period at any time after September
30, 2005 upon eighteen (18) months prior written notice, which notice may be
given at any time on or after March 1, 2004. The Joint Development Period may be
terminated at any time upon mutual consent. Notwithstanding their joint
ownership of any patent rights covering any Improvements, MSC and TST hereby
irrevocably agree that MSC shall have the exclusive rights to commercialize and
license such patent rights with respect to Licensed Products in the Field and
that TST shall have exclusive rights to commercialize and license such patent
rights with respect to Licensed Products outside of the Field. Except with
respect to the foregoing exclusive rights, neither MSC nor TST shall owe the
other any accounting or other obligation with respect to any jointly owned
patent rights, nor shall MSC be obligated to pay Running Royalties to TST on
account of products covered only by a patent solely owned by MSC or jointly
owned with TST. Subject to the provisions of Article XII, each of MSC and TST
shall promptly inform the other in writing with respect to all Improvements
invented, conceived or created by it during the Joint Development Period. [***].

     5.4  The parties shall confer with respect to the preparation of patent
applications covering any jointly owned Improvements. If the parties direct that
a patent application or application for other intellectual property protection
shall be filed on any jointly owned Improvement, then they shall determine which
party shall have responsibility for preparing and prosecuting the application.
The other party shall assist in preparing, filing, and prosecuting such United
States and foreign applications in their joint names with respect to jointly
owned Improvements. The parties shall jointly and equally bear all costs
incurred in connection with such preparation, filing, prosecution, and
maintenance of such United States and foreign application(s). MSC and TST shall
cooperate with each other to assure that such application(s) will cover, to the
best of their knowledge, all items of commercial interest and importance to
them. The party prosecuting the patent application shall keep the other party
advised as to all developments with respect to such application(s) and shall
promptly supply to the other party copies of all papers, documents and
correspondence received or filed in connection with the prosecution thereof.
Should the parties be unable to agree upon the preparation or prosecution of a
patent application covering jointly owned Improvements where the Improvement was
invented solely by one or more employees or contractors of one party, then that
party shall control preparation and prosecution of the patent application.
Should they be unable to agree upon preparation and/or prosecution of a patent
application covering a jointly owned Improvement where the Improvement was
invented jointly by employees or contractors of both parties, the parties shall
refer the matter to dispute resolution pursuant to Article IX.

     5.5  During the Joint Development Period, the parties may determine that
research and development work related to Improvements will be contracted to
third parties at the cost and expense of the parties, apportioned as they may
agree. During the Joint Development Period, neither party shall engage any third
party to conduct research or development work with regard to Licensed Products
or Improvements without first advising the other party and seeking its consent

                                       14

                                     Confidential information redacted and filed
                                                 separately with the Commission.

and an apportionment of the costs therefor. Except as otherwise agreed by the
parties, no such third party research or development shall be undertaken without
first ensuring that the parties shall acquire the right to exploit the results
of such research and development pursuant to this Agreement. On or prior to
October 14, 2002, each of TST and MSC shall provide the other with a schedule
identifying all third party research and development activities related to
possible Improvements to which it is a party.

     5.6  During the term of this Agreement, either party may acquire
proprietary information, technology or other rights ("Proprietary Rights") from
third parties that enhance the manufacture or use of the Licensed Products. To
the greatest extent commercially practicable, all such acquired Proprietary
Rights shall be subject to the terms of this Agreement, and shall be licensed to
TST or MSC, as appropriate, without further charge or expense to the licensed
party.

                   ARTICLE VI - REPRESENTATIONS AND WARRANTIES

     6.1  TST expressly warrants and represents that it owns all of the rights,
title and interest in and to the Licensed Patents, except for U.S. Patent No.
5,856,646 which it jointly owns with Allen-Bradley Company, LLC.

     6.2  TST expressly warrants and represents that it has no outstanding
encumbrances or agreements, written, oral, or implied, involving the Licensed
Patents that would conflict with the rights granted hereunder. MSC represents
and warrants that it is not a party to any agreement that conflicts with its
obligations under this Agreement.

     6.3  MSC makes no representation or warranty that it will market the
Licensed Products covered by this Agreement or, if MSC does market the Licensed
Products, that such Licensed Products shall be the exclusive means by which MSC
will participate in the Field. Furthermore, all business decisions, including
without limitation the design, manufacture, sale, price and promotion of
Licensed Products covered under this Agreement and the decision whether to sell
a particular product, shall be within the sole discretion of MSC. TST
acknowledges that MSC, without use of the Licensed Patents, may now or in the
future develop or acquire products that generally provide the same functionality
as the Licensed Products.

     6.4  TST warrants that it is aware of no patents, patent applications,
know-how or other intellectual property owned by a third party which would be
infringed by reason of the manufacture or sale or use or importation of products
covered by the Licensed Patents, and has received no notice of assertion or
claim of infringement by any third party with respect to products TST has
produced under any of the Licensed Patents.

     6.5  TST represents and warrants that it has entered into employment
agreements with each of [***] and [***] which are currently in effect, true and
correct copies of which have been provided to MSC.

                                       15

                                     Confidential information redacted and filed
                                                 separately with the Commission.

<PAGE>

     6.6  Each of the parties represents and warrants that it is authorized to
enter into this Agreement, and that it has secured such authorizations and
approvals from its board of directors or as otherwise appropriate in furtherance
of entering into this Agreement.

     6.7  TST represents and warrants that to its knowledge the claims included
in the Licensed Patents are valid and enforceable and that TST has received no
notice or claim from any third party to the contrary, other than rejections in
office actions by patent examiners.

     6.8  TST represents and warrants that it is not presently aware of any
technology or development that would or is likely to render obsolete the
Licensed Patents or render Licensed Products commercially impractical.

                     ARTICLE VII - THIRD PARTY INFRINGEMENT

     7.1  In the event that there is alleged infringement by a third party of
any of the Licensed Patents or any patents that are jointly owned by MSC and TST
pursuant to Article V with respect to Licensed Products in the Field, MSC shall
notify TST in writing to that effect, including with said written notice
evidence establishing a prima facie case of such infringement by such third
party. The prima facie determination of infringement, contributory infringement,
or inducement to infringe shall be confirmed or refuted within ninety (90) days
of notice by an independent patent attorney ("IPA"), satisfactory to the
parties, and the parties shall equally contribute to the costs of the IPA.
Should the IPA confirm the alleged infringement, TST shall have ninety (90) days
from the date of the IPA's decision to obtain a discontinuance of such
infringement or bring suit against the third party infringer.

     7.2  If, after the expiration of said ninety (90) days from the date of
said decision, TST has not obtained a discontinuance of such infringement, or
brought suit against the third party infringer, MSC shall have the right, but
not the obligation, to bring suit against such infringer and join TST as a party
plaintiff, provided that MSC shall bear all the expenses of such suit. TST will
cooperate with MSC in any suit for infringement of a Licensed Patent brought by
MSC against a third party, and shall have the right to consult with MSC and to
participate in and be represented by independent counsel in such litigation at
its own expense. MSC shall incur no liability to TST as a consequence of such
litigation or any unfavorable decision resulting therefrom, including any
decision holding any of the Licensed Patents invalid or unenforceable.

     7.3  Any and all damages or other monies received in settlement or judgment
of such suit brought by MSC shall be applied first by MSC and TST in
satisfaction of their respective litigation expenses, with any remainder
thereafter paid to MSC. In the event the damages or other monies awarded or
received in settlement are insufficient to reimburse such expenses, such damages
and monies shall be allocated pro rata between the parties based on their
percentage of expenses when compared to total expenses.

     7.4  If TST elects to bring suit against such alleged third party
infringer, then TST shall bear all the expenses of such suit. MSC, at TST's
expense, will cooperate with TST in any

                                       16

                                     Confidential information redacted and filed
                                                 separately with the Commission.

suit for infringement of any patent included in the Licensed Patents brought by
TST against a third party, and shall have the right to consult with TST and to
participate in and be represented by independent counsel in such litigation at
MSC's own expense.

     7.5  Any and all damages or other monies received in settlement or judgment
of such suit brought by TST shall be applied first by MSC and TST in
satisfaction of their respective litigation expenses, with any remainder
thereafter paid to TST. In the event the damages or other monies awarded or
received in settlement are insufficient to reimburse such expenses, such damages
and monies shall be allocated pro rata between the parties based on their
percentage of expenses when compared to total expenses. TST shall not without
MSC's prior written approval settle any such suit in a manner allowing the
alleged infringer to sell Licensed Products within the Field.

     7.6  Should any person bring an action seeking a declaratory judgment of
non-infringement and/or invalidity of any patent included in the Licensed
Patents, then TST shall have the right, but not the obligation, to litigate,
control, and settle, at its sole discretion, the action. TST shall notify MSC as
soon as reasonably possible of its intention to litigate and control the action.
Should TST determine in its sole discretion that it will not litigate and
control the action, then MSC may elect to do so. Should the party litigating the
action bring a counterclaim for infringement of a Licensed Patent and/or of a
Jointly Owned Improvement, then the provisions of Sections 7.3 and 7.5 shall
control the disposition of any recovery attributable to such action. MSC and TST
agree to cooperate in any such action. TST shall not without MSC's prior written
approval settle any such suit in a manner allowing the alleged infringer to sell
Licensed Products within the Field.

     7.7  MSC shall not advise any third party that it is infringing any patent
included in the Licensed Patents without the prior written consent of TST.

                        ARTICLE VIII - FURTHER PROVISIONS

     8.1  This Agreement or any interest herein shall not be assigned or
transferred, in whole or in part, by either party hereto without the prior
written consent of the other party hereto, such consent not to be unreasonably
withheld, conditioned or delayed. However, without securing such prior written
consent, either party may, after 30 days written notice to the other, assign
this Agreement to an Affiliate or a successor to all or substantially all of its
business to which this Agreement relates, provided that no such assignment shall
be binding and valid until and unless the assignee shall have assumed, in a
writing delivered to the non-assigning party, all of the duties and obligations

and responsible to the non-assigning party hereto for the performance and
observance of all such duties and obligations.

     8.2  A waiver of any provision of this Agreement or of any breach or
default hereunder may be affected only by a writing signed by the party against

default of the other party, shall not be construed to be a continuing waiver of
such provision or of any succeeding breach or default or a waiver of any other

     8.3  All matters affecting the interpretation, validity, and performance of
this Agreement shall be governed by the internal laws of the State of Illinois

or in conflict with the law of any jurisdiction, the validity of the remaining
part or provisions shall not be affected by such holdings.

     8.5  Any provision hereof which is prohibited or unenforceable in any

of such prohibition or unenforceability without invalidating the remaining
provisions hereof or affecting the validity or enforceability of such provision
in any other jurisdiction.

     8.6  Except as otherwise provided in Section 10.4(c), any delays in or
failures of performance by either party of any obligations other than timely
payment of monies due under this Agreement shall not be considered a breach of
this Agreement if and to the extent caused by occurrences beyond the reasonable
control of the party affected, including but not limited to: acts of God; acts,
regulations or laws of any government; strikes or other concerted acts of
workers; fires; floods; explosions; riots; wars; rebellions; and sabotage; and
any time for performance hereunder shall be extended by the actual time of delay
caused by such occurrence.

     8.7  It is the mutual desire and intent of the parties to provide certainty
as to their future rights and remedies against each other by defining the extent
of their mutual undertakings as provided herein. The parties have, in this
Agreement, incorporated all representations, warranties, covenants, commitments
and understandings on which they have relied in entering into this Agreement,
and, except as expressly provided herein, the parties make no covenant or other
commitment to the other concerning its future action. Accordingly, this
Agreement together with all Schedules, exhibits and attachments referred to
herein: (i) constitutes the entire agreement and understanding between the
parties and there are no promises, representations, conditions, provisions or
terms related thereto other than those set forth in such Agreements and (ii)
supersedes all previous understandings, agreements and representations between
the parties, written or oral.

     8.8  This Agreement may be amended only by a writing signed by both of the
parties hereto.

     8.9  All communications, reports, and notices required or permitted to be
given by one party to the other under this Agreement shall be addressed to the

     8.10 MSC agrees to mark every Licensed Product manufactured and/or sold by
it or its Affiliates under this Agreement in accordance with the statutes of the
United States and statutes in such foreign countries where patent coverage is
obtained, relating to the marking of patented articles. TST agrees to mark every
product manufactured and/or sold by it or its Affiliates and Licensees covered
by Jointly Owned Improvements in accordance with the statutes of the United
States and statutes in such foreign countries where patent coverage is obtained,
relating to the marking of patented articles.

     8.11 Except with the approval of the TST Board of Directors, through April
26, 2005, MSC shall not employ or seek to employ [***] or [***], while they are
employees of TST. Further, so long as the licenses granted herein remain
exclusive, unless an employee (other than [***] and [***]) shall have been
terminated from TST for at least one (1) year or TST's management shall have
approved such action, MSC shall not initiate contact with or solicit any such
person for purposes of employing or inducing him or her to leave the employment
of TST. Similarly, so long as the licenses granted herein remain exclusive,
unless an employee shall have been terminated from MSC for at least one (1) year
or MSC's management shall have approved such action, TST shall not initiate
contact with or solicit any such person for purposes of employing or inducing
him or her to leave the employment of MSC.

     8.12 Should either [***] or [***] terminate his employment with TST and
compete or attempt to compete with MSC, MSC's Affiliates, or MSC's sublicensees,
in each case with respect to Licensed Products in the Field, at any time prior
to April 26, 2005, then, unless TST

<PAGE>

shall have procured compliance or brought suit to enforce the non-compete
provisions of the applicable employment agreement within sixty (60) days
following notice from MSC, MSC shall have the right but not the obligation to
enforce at MSC's sole cost on behalf of TST the employment agreement, and to
name TST as a party to any such suit. TST and MSC shall cooperate fully with one
another in any such suit. TST shall have the right to be represented at its sole
cost by counsel of its choice in any suit brought by MSC pursuant hereto.

     During the period from the Effective Date until the date on which [***] or
[***], as the case may be, ceases to be an employee of TST, upon MSC's written
request and subject to MSC's undertaking to pay all premiums and other
out-of-pocket costs, TST will exert commercially reasonable efforts to obtain
and maintain key person life insurance covering the lives of either or both of
the foregoing individuals with death benefits as requested by MSC of up to two
million dollars ($2,000,000) for [***] and one million dollars ($1,000,000) for
[***] payable to MSC. If for any reason MSC cannot be a direct beneficiary of
any such policy, then TST will collect the death benefit and promptly thereafter
remit any equal amount to MSC.

     8.13 Neither party without the approval of the other shall originate any
publicity, news release or public announcement, written or oral, whether to the
public or press, public stockholders or otherwise, relating to this Agreement,
performance under it or any of its terms, any amendment hereto or performance
thereunder save only such announcements as in the opinion of counsel for the
party making such announcement is required by law to be made or pursuant to the
agreement of the parties, such agreement to be given reasonably. Notwithstanding
the foregoing, either party may disclose to actual or potential customers the
existence of this Agreement and the general subject matter to which it relates.

     8.14 With respect to product types indicated on Schedule 1B as potentially
being marketed both within and outside of the Field and in other circumstances
in which either MSC or TST raises a question with regard to whether a particular
product or a particular proposed transaction or series of transactions will be
within the Field, the parties agree to confer and negotiate in good faith to
reach agreement on a case-by-case basis. In the event the parties fail to reach
agreement, the issue shall be referred for resolution as provided in Article IX.
Further, in dealing with such products and with customers operating both within
and outside the Field, the parties intend to cooperate in a manner that will
best serve such customers and best utilize the parties' respective resources,
skills and competitive advantages in such areas as product design,
manufacturing, marketing and customer support. The parties will negotiate in
good faith to arrive at mutually agreeable arrangements directed toward such
ends on a case-by-case and/or customer-by-customer basis.

     8.15 Should MSC become aware of an opportunity for commercialization of the
Licensed Patents outside of the Field and outside of the fields of business then
being pursued directly by TST and its Affiliates (which latter fields include
but are not limited to the fields of appliances, commercial products, medical
products and exercise equipment), then it may notify TST of the opportunity and
request that the definition of the Field in this Agreement be expanded to cover
that opportunity. TST under no circumstances shall be obligated to agree to
expand the

                                     Confidential information redacted and filed

<PAGE>

definition of the Field hereunder, or to refrain from pursuing such opportunity
for itself and its Affiliates, but shall in good faith negotiate with MSC with
regard to any such opportunity. If TST and MSC do not agree to such an expanded
definition of the Field, unless TST had previously been pursuing the opportunity
identified by MSC, [***].

     8.16 The parties shall from time to time, not less frequently than once in
each calendar quarter, meet in order to review MSC's exploitation of the rights
and licenses herein granted, and to review TST's efforts to develop
Improvements.

     8.17 This Agreement is only between MSC and TST, and does not create any
rights on behalf of any parties other than MSC and TST and, to the extent
expressly set forth herein, their respective Affiliates.

     8.18 If TST shall have an involuntary petition filed against it or shall
file a voluntary petition under the bankruptcy laws of the United States, the
parties intend that MSC shall be protected in the continued enjoyment of its
rights hereunder to the maximum feasible extent, including, without limitation,
if MSC so elects, the protection conferred upon MSC under Section 365(n) of
Title 11 of the United States Code (the "Bankruptcy Code"), or any similar
provision of any applicable law. The Licensed Patents and Know-How, for the
purposes of Section 365(n) of the Bankruptcy Code, are deemed to be
"intellectual property" as that term is defined in Section 101(35A) of the
Bankruptcy Code. All materials required to be delivered by TST to MSC hereunder,
and all materials relating to the Licensed Patents, Licensed Products, and
Know-How which, in the course of dealing between the parties under this
Agreement, are customarily delivered, are considered to be "embodiments" of such
intellectual property and intellectual property rights for purposes of said
Section 365(n). All written agreements entered into in connection with the
parties' performance hereunder from time to time are considered agreements
"supplementary" to this Agreement for purposes of Section 365(n) of the
Bankruptcy Code. At the request of MSC and at its cost, TST shall grant a
security interest in Licensed Patents and Know-How in favor of MSC, which
security interest may be recorded by MSC as it deems appropriate. Such security
interest, if granted, shall be solely to secure the continued enjoyment by MSC
of its rights hereunder and shall expire immediately at such time as the license
granted hereunder ceases to be exclusive. MSC may at its discretion record
pertinent portions of this Agreement with the United States Patent and Trademark
Office, but prior to doing so, MSC will exert all commercially reasonable
efforts to notify and confer with TST regarding the specific portions it intends
to record.

                         ARTICLE IX - DISPUTE RESOLUTION

     9.1  Should the parties at any time be unable to reach agreement as to any
matter entrusted to their joint determination, then they shall refer the matter
for resolution to their respective senior management who shall receive such
information as the parties deem desirable and who shall meet forthwith in an
attempt to amicably resolve matters.

<PAGE>

     9.2 Should senior management be unable to resolve a dispute as provided in
Section 9.1 within 45 days following such referral, then any and all disputes
between the parties relating in any way to entering into of this Agreement
and/or the validity, construction, meaning, enforceability, or performance of
this Agreement or any of its provisions, or the intent of the parties in
entering into this Agreement, or any of its provisions shall be settled by
arbitration. Such arbitration shall be conducted at Chicago, Illinois, in
accordance with the rules then pertaining to the American Arbitration
Association with a panel of three (3) arbitrators. The panel of arbitrators
shall be selected by agreement of the parties, but if the parties cannot agree
on the panel within thirty (30) days, each party shall select one arbitrator and
the two arbitrators so selected shall select the third arbitrator. The
arbitrators shall be selected from the National Panel of Arbitrators of the
American Arbitration Association. Reasonable discovery as determined by the
Arbitrators shall apply to the arbitration proceeding. Judgment upon the award
rendered by the arbitrators may be entered in any court having jurisdiction
thereof. The prevailing party in such arbitration, in addition to all other
relief provided, may be awarded its reasonable costs and expenses including
attorney costs, in each case as determined by the arbitrators in their sole
discretion. Notwithstanding the foregoing, either party may initiate or continue
a proceeding in a court of competent jurisdiction in order to obtain injunctive
relief in order to preserve the status quo ante or to protect and preserve its
intellectual property rights, at any time, including but not limited to any
period in which an arbitration proceeding is pending hereunder.

                        ARTICLE X - TERM AND TERMINATION

     10.1 The term of this Agreement shall be for a term commencing on the
Effective Date and, unless sooner terminated, extending until expiration of the
last to expire of all patents included in the Licensed Patents or until there
remains no Valid Claim under the Licensed patents, whichever occurs earlier.

     10.2 MSC may in its discretion terminate this Agreement and the licenses
and rights granted herein:

          (a)  if TST shall at any time commit a material default or be in
     material breach under any term or condition of this Agreement and fails to
     reasonably cure such default or breach within forty-five (45) days after
     receipt of written notice from MSC reasonably specifying the default or
     breach; or

          (b)  without cause at any time after March 1, 2006 upon one hundred
     twenty (120) days prior written notice to TST; or

          (c)  if at any time prior to April 26, 2005 either or both of [***] or
     [***] ceases to be employed by TST or is determined to be permanently
     disabled as set forth in their respective employment agreements described
     in Section 6.5 of this Agreement.

Notwithstanding the foregoing, MSC's right to terminate pursuant to subsection
(c) above may only be exercised upon thirty (30) days advanced written notice
given to TST within ninety (90)

                                       22

days following the date on which MSC receives notice that either or both of the
named individuals has ceased to be employed by TST and then only if such
individuals are not employed or have not agreed to become employed by MSC or its
Affiliates. Further, MSC shall have no right to terminate pursuant to subsection
(c) above in the event either or both of the named individuals has ceased to be
employed by reason of his death, provided that MSC is either the beneficiary of
a key person life insurance policy covering such individual as provided in
Section 8.12 or TST pays to MSC an amount equal to the amount of the benefits
payable under such a policy or, if no such policy is then in force, an amount
equal to One Million Dollars ($1,000,000) in the event of the death of [***] or
Two Million Dollars ($2,000,000) in the event of the death of [***].

     10.3 In the event MSC is entitled to terminate this Agreement and its
rights and licenses hereunder pursuant to the provisions of Section 10.2, it may
instead in its sole discretion elect, by written notice to TST, to continue to
be licensed under this Agreement on a non-exclusive basis.

     10.4 TST may in its discretion terminate this Agreement and the licenses
and rights granted herein:

          (a)  if MSC shall at any time be in default with respect to any
     payment due hereunder and fail to cure such default within fifteen (15)
     days after receipt of written notice from TST; or

          (b)  if MSC shall at any time commit any other material default or be
     in material breach under any term or condition of this Agreement and fails
     to reasonably cure such default or breach within forty-five (45) days after
     receipt of written notice from TST reasonably specifying the default or
     breach; or

          (c)  upon written notice from TST if MSC shall, for any reason,
     suspend or cease conducting all of its business related to Licensed
     Products for a period of one hundred twenty (120) consecutive days or for
     periods totaling one hundred eighty (180) days in any calendar year.

     10.5 In the event TST is entitled to terminate this Agreement and MSC's
rights and licenses hereunder pursuant to the provisions of Section 10.4, it may
instead, in its sole discretion, elect, by written notice to MSC, to terminate
only the exclusivity of any or all of the licenses granted to MSC hereunder.
Notwithstanding any other provision of this Agreement, in the event that this
Agreement and the licenses and rights granted hereunder or exclusivity with
respect thereto is terminated by TST pursuant to Section 10.4 at any time prior
to March 1, 2006, MSC shall nevertheless continue to be obligated to pay Minimum
Annual Royalties for all periods through February 28, 2006, and in the case of
termination of this Agreement, all such amounts shall become immediately due and
payable on the termination date.

     10.6 In the event of termination of this Agreement or the licenses and
rights granted hereunder by MSC pursuant to Section 10.2 above, then MSC shall
be entitled to continue to manufacture and sell Licensed Products and TST shall
have an obligation to support MSC customers and sublicensees for a period of up
to one hundred eighty (180) days solely in order to dispose of inventory on hand
at the time of termination and fulfill customer orders received and accepted
prior to the time of termination, subject in each case to continuing payment of
royalties with respect to such sales.

     10.7 The terms, conditions and provisions of the following sections shall
survive the expiration or termination of this Agreement: Article I, Section
2.5(f), Article III, Article IV, Sections 5.3, 5.4, 7.2 through 7.6 (as to
litigation pending prior to termination), 8.1 through 8.11, 8.13, 8.17, Article

                        ARTICLE XI - WARRANTY LIMITATIONS

     11.1 Nothing in this Agreement shall be construed as:

          (a)  a warranty or representation by TST as to the scope of any patent
     included in Licensed Patents; or

          (b)  a requirement that TST shall file any patent application, secure
     any patent, or maintain any patent in force; or

          (c)  an obligation to bring or prosecute actions or suits against
     third parties for infringement.

                           ARTICLE XII-CONFIDENTIALITY

     12.1 "Confidential Information" as used herein shall mean all non-public
information, documentation, software (including listings thereof and
documentation related thereto), blueprints, drawings, sketches, trade secrets,
Know-How and other confidential research, development or manufacturing data
regardless of the media in which the foregoing may be stored that concerns or
relates to the business, prospects, processes, operations, employees,
contractors, suppliers, customers, strategic, operating marketing and sales
plans, financial and tax accounting data of a party or with respect to which a
party is obligated to maintain confidentiality. In order for information to be
considered confidential hereunder, it shall be stamped, marked, or otherwise so
indicated by TST or MSC by applying to the information the notation
"Confidential Information". Notwithstanding anything to the contrary herein and
without any marking requirement, the substantive terms and conditions of this
Agreement other than the existence and general scope of licenses and rights
granted hereunder with respect to the Licensed Patents, shall be deemed
Confidential Information of both parties, with each owing a duty of
confidentiality to the other.

     This Agreement shall not be construed to prevent a party from making use of
or disclosing information which:

     A.   was lawfully in its possession subject to no obligations of
          confidentiality prior to the production of such information by the
          disclosing party; or

     B.   appears in any issued patent, printed publication, or other published
          or circulated material available to the general public; or

     C.   was or is hereafter obtained from a source or sources not under an
          obligation of secrecy to the disclosing party; or

     D.   is exempted from the operation of this Agreement by written consent of
          the disclosing party.

     Further this Agreement shall not be construed to prevent a receiving party
from disclosing Confidential Information of a disclosing party to the extent
such disclosure is compelled by a court or other governmental authority or
otherwise required under applicable law, provided that such receiving party
shall exert reasonable efforts to notify the disclosing party of such impending
disclosure and shall cooperate in seeking an appropriate protective order or
other action to prevent or restrict disclosure.

     12.2 Each party acknowledges and agrees that Confidential Information is
proprietary to the disclosing party and that any unauthorized disclosure or
unauthorized use thereof by the receiving party will cause irreparable harm and
loss to the disclosing party. In the event of actual or threatened breach of
this Agreement by a receiving party or one of its employees to whom Confidential
Information of the other party has been disclosed, the disclosing party shall be
entitled to secure an immediate preliminary injunction prohibiting disclosure of
its Confidential Information, which action shall not restrict or limit any other
remedies, legal or equitable, that the disclosing party might determine to seek.

     12.3 In consideration of the disclosure to the receiving party of
Confidential Information, the receiving party agrees to treat Confidential
Information of the disclosing party in confidence and to undertake the following
additional obligations with respect thereto:

          (a)  to use such Confidential Information for the sole purpose of
     performing its obligations and exercising its rights under this Agreement
     including but not limited to developing Improvements;

          (b)  not to copy, in whole or in part, such Confidential Information
     except as may be necessary or useful in connection with the purposes
     described in Section 12.3(a);

          (c) not to disclose such Confidential Information to any third parties
     other than professional and financial advisors, consultants and contractors
     as and to the extent

                                       25

     necessary or useful in connection with the purposes described in Section
     12.3(a) and then only if such third parties are legally bound to maintain
     such Confidential Information in confidence;

          (d)  to limit dissemination of such Confidential Information to only
     those of receiving party's employees, officers, directors, contractors,
     professional advisors, bankers and investors who have a need to know for
     the purposes described in Section 12.3(a) above and who are subject to
     binding obligations to hold the Confidential Information disclosed to them
     in confidence; and

          (e)  to return or destroy all materials containing such Confidential
     Information, other than jointly owned Confidential Information including
     all copies and records thereof, upon any termination or expiration of this
     Agreement and certify in a writing signed by an officer that the same has

                            ARTICLE XIII- COMPONENTS

     13.1 During the term of this Agreement, subject to the ability of TST or
its contract manufacturers to supply Chips that meet MSC's quality standards and
requirements for quantity, delivery and service as MSC in its sole discretion
shall determine, all of the respective requirements of MSC, its Affiliates and
its sublicensees for TST's proprietary Chips for use in manufacturing Licensed
Products shall be purchased from TST at prices equal to TST's cost, as defined
in Section 13.5 below, subject to adjustment pursuant to Section 2.8 (providing
that TST may increase the price of such Chips purchased for sale to sublicensees
under new Manufacturing Sublicenses to its cost divided by [***] in the event
that MSC's license and rights hereunder become non-exclusive) and pursuant to
Section 13.6 (providing for prices greater than actual cost in certain
circumstances). Nothing in this Section 13.1 shall obligate TST to make any
changes or modifications to the designs of any Chips, but TST will consider
requests for such changes or modifications.

          (a)  For purposes of this Section 13.1, TST's cost shall mean TST's
     costs and expenses as set forth in Section 13.5.

          (b)  Should TST be unable or unwilling to satisfy the requirements of
     MSC, its Affiliates and/or its sublicensees for Chips pursuant to this
     Section 13.1, MSC shall have the right to make the Chips or have them made
     to supply its requirements and the requirements of its Affiliates and
     sublicensees. MSC will be responsible for any breach of its obligations
     under this Agreement by its Affiliates and Sublicensees, even if the breach
     was actually committed by a contract manufacturer. MSC shall undertake to
     utilize a contract manufacturer for Chips only where such contract
     manufacturer is held to standards no less stringent than those applied to
     TST Should MSC undertake to make Chips or have them made for use in
     Licensed Products pursuant to this Article XIII, TST shall not be
     responsible for any costs or expenses associated with any such manufacture,
     including, without limitation, direct labor and material costs. The
     manufacturing rights provided in this Section 13.1(b) shall be MSC's sole
     and exclusive remedy for any breach by TST of any obligation hereunder to
     supply Chips. Subject to Article XII of this Agreement, TST agrees to
     provide MSC with the documents, information, masks, mask works, and
     Know-How necessary or useful in manufacturing the Chips, including, without
     limitation, manufacturing specifications and tolerances, technical
     drawings, and schematics, as necessary or useful to enable MSC to exercise
     its manufacturing rights in accordance with this Section 13.1(b). The
     parties further agree that MSC and its Affiliates and sublicensees shall
     comply with all applicable laws and regulations, including consumer
     protection and safety legislation, in manufacturing the Chips.

          (c)  At any time at which MSC is unable to compete effectively in any
     relevant market within the Field because the cost of Chips supplied by TST
     hereunder is not competitive with the cost of comparable Chips available to
     MSC from other sources, MSC shall so notify TST in writing and the parties
     shall cooperate and jointly exert commercially reasonable efforts to reduce
     such costs to levels that would reasonably be expected to enable MSC to be
     competitive, such efforts to include, but not be limited to,

     seeking alternative sourcing for Chip fabrication. Should the parties fail
     to agree on cost reduction actions to be taken pursuant to this Section
     13.1(c) resolution of any such disagreement or dispute shall be pursued in
     accordance with Article IX.

     13.2 During the term of this Agreement, TST and its Affiliates shall have
the right but not the obligation to purchase from MSC Assembled Flexible
Substrates for use in furtherance of the manufacture of Licensed Products, such
Assembled Flexible Substrates to be made available by MSC to TST and its
Affiliates based upon MSC's cost (materials and direct labor, determined by
reference to MSC's books and records regularly kept in accordance with GAAP),
divided by [***]. MSC shall be the preferred vendor of TST and its Affiliates,
respectively, for the Assembled Flexible Substrates, provided that MSC's price,
quality, delivery, and service are reasonably satisfactory to TST and its
Affiliates, respectively. Nothing herein shall grant TST and its Affiliates any
right to sell Licensed Products in the Field during any period in which MSC's
rights and license hereunder with respect thereto are exclusive.

     13.3 During the term of this Agreement, MSC and its Affiliates shall have
the right but not the obligation to purchase from TST assembled glass substrates
and printed circuit boards ("PCBs") for use in furtherance of the manufacture of
Licensed Products, such assembled glass substrates and PCBs to be made available
by TST to MSC and its Affiliates, based upon TST's cost (materials and direct
labor, determined by reference to TST's books and records regularly kept in
acceptance with GAAP), divided by [***]. TST shall be the preferred vendor of
MSC and its Affiliates for the assembled glass substrates and PCBs, provided
that TST's price, quality, delivery, and service are reasonably satisfactory to
MSC and its Affiliates, respectively.

     13.4 Each of the parties shall keep complete and accurate records of its
costs to manufacture/acquire the components called for by this Article XIII in
accordance with GAAP. Each of the parties shall have the right, at its sole
discretion and expense, to nominate an independent accountant reasonably
acceptable to and approved by the other party, acceptance and approval not to be
unreasonably withheld, conditioned or delayed, who shall have access to the
other party's records, after executing a Confidentiality Agreement acceptable to
the other party, during reasonable business hours for the purpose of verifying
the costs specified in this Article XIII for the two preceding Fiscal Years, but
this right may not be exercised more than once in any Fiscal Year, and the
accountant shall disclose to the party only information relating solely to the
accuracy of the costs and the correct amounts paid and payable by the other
parties pursuant to this Article XIII.

     13.5 [***].

     13.6 In connection with the supply of Chips by TST pursuant to Section
13.1, TST may from time to time propose to engage in capital investment programs
intended to reduce the cost of the Chips. TST may request that MSC participate
in such proposed programs. MSC shall have no obligation to so participate, but
if it does not, then notwithstanding the provisions of Section 13.1, MSC shall
not benefit from the actual Chip cost reduction, if any, resulting solely

                                       28

<PAGE>

from such capital investment by TST and the price paid by MSC for Chips supplied
under Section 13.1 shall thereafter be adjusted accordingly.

     13.7 Whenever a party supplying any articles pursuant to this Article XIII
anticipates or determines that its costs will increase in a manner that would
reasonably be expected to result in a substantial increase in the price of such
articles, the supplying party will exert commercially reasonable efforts to
notify the purchasing party of its best estimate of such increase and the
anticipated basis therefor at least thirty (30) days in advance.

                               ARTICLE XIV-SUPPORT

     14.1 TST shall assign sufficient skilled engineering staff throughout the
term of this Agreement to enable timely communication to MSC of the intellectual
property being licensed under this Agreement, including but not limited to
communication of all hereafter developed Know-How and Improvements. In addition,
TST shall employ sufficient engineers to communicate on a timely basis technical
information and provide support reasonably requested by MSC to facilitate MSC's
development of Licensed Products. For the period through February 28, 2003,
however, TST shall not be obligated to provided such support in excess of [***]
hours. For Fiscal Years ending after February 28, 2003, TST shall not be
obligated to provided such support in excess of [***] hours in any Fiscal Year.
Unless otherwise agreed by the parties, the obligations of TST under this
Section 14.1 shall cease at any time when MSC ceases to be subject to Minimum
Annual Royalty payment obligations.

     14.2 MSC shall employ reasonably skilled engineers, at least one of whom is
an electronics engineer, and technicians to timely receive from TST the
technical information, Know-How, and intellectual property being licensed
pursuant to this Agreement.

                          ARTICLE XV - SALE OF LICENSES

     15.1 MSC may determine that it desires to sell and transfer all of its
rights and obligations under this Agreement with respect to the transportation
market and/or the consumer electronics market as defined and included in the
Field (the "Transferred Field") to another party (a "Buyer") in a transaction
under which the Buyer would become a licensee entitled to exercise all rights
and privileges under this Agreement and under Sublicenses with respect to
Licensed Products in the Transferred Field, would be deemed a successor in
interest of MSC with respect thereto and would assume a portion of MSC's
obligations, including but not limited to the payment of Total Royalties related
to Transferred Field (a "Sale Transaction").

     15.2 In the event MSC proposes a Sale Transaction pursuant to this Article
XV, MSC shall first notify TST and afford it the opportunity to re-acquire
rights with respect to the Transferred Field upon mutually agreeable terms and
conditions negotiated in good faith. If MSC and TST should fail to negotiate and
execute a mutually agreeable Sale Transaction within sixty (60) days following
TST's receipt of such notice, then MSC shall be free to negotiate a Sale
Transaction with a third party Buyer on terms not less favorable than those
offered by TST, if any. Prior to entering into any such Sale Transaction, MSC
shall provide TST with a written

                                       29

                                     Confidential information redacted and filed

notice identifying the name and address of the proposed Buyer and setting forth
in detail all of the material terms of the proposed Sale Transaction. MSC shall
not enter into any such Sale Transaction without the prior approval of TST,
which approval shall not be unreasonably withheld, conditioned or delayed. If
TST fails to give MSC written notice to the contrary within thirty (30) days
following TST's receipt of the foregoing notice of the identity of the proposed
Buyer and the terms of the proposed Sale Transaction, then TST shall be deemed
to have approved such Sale Transaction.

     15.3 In the event that MSC effects a Sale Transaction, it shall pay to TST
a portion of the Adjusted Net Proceeds (as defined below) of such Sale
Transaction as set forth below:

          (a)  Such payment shall be made on the date on which the Sale
     Transaction is consummated and shall be accompanied by a written closing
     statement showing the calculation for determining the amount of such
     payment in accordance herewith. Such statement shall be delivered even if
     no amount is payable to TST pursuant hereto.

          (b)  For Sales Transactions as to which a notice is given prior to
     March 1, 2004 and which are consummated prior to March 1, 2005, MSC shall
     pay TST [***] of the Adjusted Net Proceeds (as defined below), if any, plus
     [***] of Other Valuable Consideration (as defined below), if any.

          (c)  For all other Sales Transactions, MSC shall pay TST [***] of the
     Adjusted Net Proceeds, if any, plus [***] of Other Valuable Consideration,
     if any.

          (d)  For purposes of this Section 15.3:

               (i)   "Adjusted Net Proceeds" shall mean the Gross Proceeds (as
                     defined below), net of the reasonable out-of-pocket
                     expenses incurred by MSC in connection with effecting such
                     Sale Transaction.

               (ii)  "Gross Proceeds" shall mean the total consideration paid or
                     payable by the Buyer to MSC and its Affiliates in the Sale
                     Transaction, whether paid in cash, securities or property,
                     or by assumption of indebtedness for borrowed money.
                     Consideration other than cash and cash equivalents shall be
                     valued at fair market value and any deferred payments shall
                     be discounted to net present value using a discount rate
                     equal to [***] per annum.

               (iii) "Other Valuable Consideration" shall mean the portion of
                     the ongoing Minimum Annual Royalty obligations of MSC
                     assumed by the Buyer during the Fiscal Years ending prior
                     to March 1, 2006, discounted to net present value using a
                     discount rate equal to [***] per annum. To the extent that
                     Minimum Annual Royalties assumed by the Buyer for which MSC
                     has paid Other Valuable

                     Consideration in connection with the Sales Transaction
                     (Other Valuable Consideration) are ultimately paid by the
                     Buyer to TST, Other Valuable Consideration shall be
                     proportionately reduced retroactively. Within forty-five
                     (45) days following the last day of each Fiscal Year ending
                     prior to March 1, 2006, TST shall pay to MSC an amount
                     equal to the Minimum Annual Royalties received from the
                     Buyer during such Fiscal Year with respect to which MSC has
                     previously paid Other Valuable Consideration, or credit
                     such amount against the next required Minimum Annual
                     Royalty payment by MSC. Each such payment or notice of such
                     credit shall be accompanied by a report setting forth the
                     calculation of the amounts to be paid or credited and the
                     basis therefor.

     15.4 All calculations of Adjusted Net Proceeds, Other Valuable
Consideration and Minimum Annual Royalties paid by the Buyer for purposes of
this Article XV shall be based upon accounts and records maintained in
accordance with GAAP, and MSC and TST, respectively, shall keep accurate records
that are sufficiently detailed and complete to permit an examination for
purposes of verifying the accuracy of the foregoing calculations, of the amounts
of Adjusted Net Proceeds and Other Valuable Consideration paid or payable by MSC
to TST pursuant to this Article XV, and of the amounts of Minimum Annual
Royalties paid by the Buyer to TST and the amounts paid or payable by TST to MSC
pursuant to Section 15.3(d)(iii). TST shall have the right, at its sole
discretion and expense, upon written notice given within ninety (90) days
following TST's receipt of the statement of the calculation of the amount
payable to TST with respect to each Sale Transaction pursuant to this Article
XV, and MSC shall have the right, at its sole discretion and expense, upon
written notice given within ninety (90) days following MSC's receipt of each
report pursuant to Section 15.3(d)(iii), to nominate an independent accountant
reasonably acceptable to and approved by MSC or TST, as the case may be, such
acceptance and approval not to be unreasonably withheld, conditioned or delayed.
Such accountant shall have access to MSC's or TST's records, as the case may be
(after executing a confidentiality agreement reasonably acceptable to MSC or
TST, as the case may be), during reasonable business hours for the purpose of
inspecting and examining such records and verifying the amounts paid or payable
to TST or MSC, as the case may be, under this Article XV.

this Purchase Agreement; or
