<PAGE>

      9.2 TPL Agreement to Indemnify. TPL shall indemnify and hold harmless
Patriot and its Representatives (collectively, the "Patriot Indemnitees") in
respect of any and all Damages which any of the Patriot Indemnitees may incur or
sustain, or to which any of the Patriot Indemnitees may be subjected, as a
result of:

            (a) any inaccuracy or misrepresentation in or breach of any
representation or warranty contained in this Agreement;

            (b) any breach by TPL of any covenant or agreement to be performed

            (a) any inaccuracy or misrepresentation in or breach of any
representation or warranty contained in Article V of this Agreement; or

            (b) any breach by Moore of any covenant or agreement to be performed
by Moore.

      9.4 Survival of Representations, Warranties and Covenants. All
representations, warranties, covenants, agreements and obligations of each
Indemnifying Party contained in this Agreement and all claims of any TPL
Indemnitee or Patriot Indemnitee in respect of any breach of any representation,
warranty, covenant, agreement or obligation of any Indemnifying Party contained
in this Agreement, shall survive the Closing and all due diligence performed by
the respective parties.

      9.5 Claims for Indemnification. If any Indemnitee shall believe that such
Indemnitee is entitled to indemnification pursuant to this Article IX in respect
of any Damages, such Indemnitee shall give the appropriate Indemnifying Party
prompt written notice thereof. Any such notice shall set forth in reasonable
detail and to the extent then known the basis for such claim for
indemnification. The failure of such Indemnitee to give notice of any claim for
indemnification promptly shall not adversely affect such Indemnitee's right to
indemnity hereunder except to the extent that such failure adversely affects the
right of the Indemnifying Party to assert all reasonable defenses to such claim.
Each such claim for indemnity shall expressly state that the Indemnifying Party
shall have only the thirty (30) calendar day period referred to in the next
sentence to dispute or deny such claim. The Indemnifying Party shall have thirty

                                       23
<PAGE>

(30) calendar days following its receipt of such notice either (a) to acquiesce
in such claim and the responsibility to indemnify the Indemnitee in respect
thereof in accordance with the terms of this Article IX by giving such
Indemnitee written notice of such acquiescence or (b) to object to the claim by
giving such Indemnitee written notice of the objection. If the Indemnifying
Party does not object thereto within such thirty (30) calendar day period, the
Indemnifying Party shall be deemed to have acquiesced in such claim and the
responsibility to indemnify the Indemnitee in respect thereof in accordance with
the terms of this Article IX.

      9.6 Defense of Claims. In connection with any claim which may give rise to
indemnity under this Article IX resulting from or arising out of any claim or
Proceeding against an Indemnitee by a Person that is not a party hereto, the
Indemnifying Party may (unless such Indemnitee elects not to seek indemnity
hereunder for such claim), upon written notice sent at any time to the relevant
Indemnitee, assume the defense of any such claim or Proceeding if the
Indemnifying Party with respect to such claim or Proceeding acknowledges to the
Indemnitee the Indemnitee's right to indemnity pursuant hereto in respect of the
entirety of such claim (as such claim may have been modified through written
agreement of the parties or arbitration hereunder) and provide assurances,
reasonably satisfactory to such Indemnitee, that the Indemnifying Party will be
financially able to satisfy such claim in full if such claim or Proceeding is
decided adversely. The Indemnifying Party shall select counsel reasonably
acceptable to such Indemnitee to conduct the defense of such claim or
Proceeding, shall take all steps reasonably necessary in the defense or
settlement thereof and shall at all times diligently and promptly pursue the
resolution thereof. If the Indemnifying Party shall have assumed the defense of
any claim or Proceeding in accordance with this Section 9.6, the Indemnifying
Party shall not (without the written consent of each Indemnitee) consent to a
settlement of, or the entry of any judgment arising from, any such claim or
Proceeding, unless such settlement or order shall provide for the unconditional
release of all Indemnitees. If the Indemnifying Party has so elected to assume
the defense, each Indemnitee shall be entitled to participate in (but not
control) the defense of any such action, with its own counsel and at its own
expense. Each Indemnitee shall, and shall cause each of its Representatives to,
cooperate fully with the Indemnifying Party in the defense of any claim or
Proceeding being defended by the Indemnifying Party pursuant to this Section
9.6. If the Indemnifying Party does not assume the defense of any claim or
Proceeding resulting therefrom in accordance with the terms of this Section 9.6,
such Indemnitee may defend against such claim or Proceeding in such manner as it
may deem appropriate, provided that the Indemnitee may not settle such claim or
Proceeding without the written consent of the Indemnifying Party (which consent
shall not be unreasonably withheld or delayed), and provided further that the
Indemnifying Party shall be obligated to pay Indemnitee's attorneys' fees and
costs promptly as they are incurred in the defense of such claim or Proceeding.

      10.1 Grounds for Termination. This Agreement may be terminated (except as
set forth in Section 10.2) and the transactions contemplated hereby abandoned at
any time prior to the Closing (the "Termination Date"):

            (a) by mutual written agreement of TPL and Patriot;

                                       24
<PAGE>

            (b) by TPL upon written notice to Patriot of any one or more
inaccuracies or misrepresentations in or breaches of the representations or
warranties made by Patriot contained herein which have had or, if not cured
prior to the Closing Date could be reasonably expected to have, a Material
Adverse Effect when taken into account with all other uncured inaccuracies or
misrepresentations in or breaches of such representations or warranties;
provided, however, that a termination pursuant to this clause (b) shall become
effective upon the earlier to occur of (i) fifteen (15) days after such notice
with respect to such a misrepresentation or breach that is not capable of being
cured on or prior to the Closing Date, or (ii) immediately prior to the Closing
with respect to such a misrepresentation or breach that is capable of being
cured, but is not cured, on or prior to the Closing Date;

            (c) by TPL at any time upon written notice to Patriot of the failure
by Patriot to perform and satisfy in all material respects any of its
obligations under this Agreement required to be performed and satisfied on or
prior to the Closing Date; provided, however, that a termination pursuant to
this clause (c) shall become effective upon the earlier to occur of (i) three
(3) days after such notice with respect to such a failure that is not capable of
being cured on or prior to the Closing Date, (ii) fifteen (15) days after such
notice with respect to such a failure that is capable of being cured on or prior
to the Closing Date, but is not cured, on or prior to such fifteenth (15th) day,
or (iii) immediately prior to the Closing with respect to such a failure that is
capable of being cured, but is not cured, on or prior to the Closing Date;

            (d) by Patriot at any time upon written notice to TPL of any one or
more inaccuracies or misrepresentations in or breaches of the representations or
warranties made by TPL or Moore contained herein which have had or, if not cured
prior to the Closing Date could be reasonably expected to have, a Material
Adverse Effect when taken into account with all other uncured inaccuracies or
misrepresentations in or breaches of such representations or warranties;
provided, however, that a termination pursuant to this clause (d) shall become
effective upon the earlier to occur of (i) fifteen (15) days after such notice
with respect to such a misrepresentation or breach that is not capable of being
cured on or prior to the Closing Date, or (ii) immediately prior to the Closing
with respect to such a misrepresentation or breach that is capable of being
cured, but is not cured, on or prior to the Closing Date;

            (e) by Patriot at any time upon written notice to TPL of TPL's
failure to perform and satisfy in all material respects any of its obligations
under this Agreement required to be performed and satisfied on or prior to the
Closing Date; provided, however, that a termination pursuant to this clause (e)
shall become effective upon the earlier to occur of (i) three (3) days after
such notice with respect to such a failure that is not capable of being cured on
or prior to the Closing Date, (ii) fifteen (15) days after such notice with
respect to such a failure that is capable of being cured on or prior to the
Closing Date, but is not cured, on or prior to such fifteenth (15th) day, or
(iii) immediately prior to the Closing with respect to such a failure that is
capable of being cured, but is not cured, on or prior to the Closing Date;

            (f) by Patriot or TPL if the Closing shall not have been consummated
by November 30, 2005; provided, however, that Patriot or TPL may not terminate
this Agreement pursuant to this clause (f) if the Closing shall not have been
consummated within such time period by reason of the failure of that party or
any of its Representatives to perform in all material respects any of its or
their respective covenants or agreements contained in this Agreement;

                                       25
<PAGE>

            (g) by Patriot if TPL has caused a Material Adverse Effect other
than any Material Adverse Effect caused by any proceeding brought by any current
or former affiliate, Representative, stockholder, creditor or stakeholder of
Patriot relating to any effect of the public announcement of this Agreement, the
transactions contemplated hereby or the consummation of such transactions;

            (h) by TPL if Patriot has caused a Material Adverse Effect; and

            (i) by any party hereto if any federal, state or foreign law or
regulation thereunder shall hereafter be enacted or become applicable that makes
the transactions contemplated hereby or the consummation of the Closing illegal
or otherwise prohibited, or if any judgment, injunction, order or decree
enjoining either party hereto from consummating the transactions contemplated
hereby is entered, and such judgment, injunction, order or decree shall become
final and nonappealable.

      The party desiring to terminate this Agreement pursuant to clauses (b)
through (i) shall give written notice of such termination to the other party
pursuant to Section 11.1.

      10.2 Effect of Termination.

            (a) If this Agreement is terminated as permitted by Section 10.1,
such termination shall be without liability of any party to any other party to
this Agreement except as hereinafter expressly provided in this Section 10.2.

            (b) If such termination shall result from the willful failure of
Patriot to fulfill a condition to the performance of the obligations of TPL, the
willful failure of Patriot to perform a covenant contained in this Agreement or
a willful breach by Patriot of its representations and warranties contained in
this Agreement, Patriot shall be fully responsible for all Damages incurred by
TPL as a result of such failure or breach by Patriot.

            (c) If such termination shall result from the willful failure of TPL
to fulfill a condition to the performance of the obligations of Patriot, the
willful failure of TPL to perform a covenant contained in this Agreement or a
willful breach by TPL of its representations and warranties contained in this
Agreement, TPL shall be fully responsible for all Damages incurred by Patriot as
a result of such failure or breach by TPL.

            (d) If such termination shall result for any reason other than (i)
the willful failure of Patriot to fulfill a condition to the performance of the
obligations of TPL; (ii) the willful failure of Patriot to perform a covenant
contained in this Agreement; or (iii) the willful breach by Patriot of its
representations and warranties contained in this Agreement, Patriot shall be
entitled to one-half of the Net Cash Proceeds generated by TPL from the period
beginning from the date hereof and ending on the date this Agreement is
terminated. It is expressly agreed and understood that Patriot shall not be
entitled to any of the Milestone Payments (as such term is defined in the Intel
Patent License Agreement), which shall only be distributed pursuant to the terms
of the Escrow Agreement. TPL shall pay Patriot, by wire transfer in immediately
available funds, to the account set forth on Exhibit E of the Escrow Agreement,
such funds within the later of (A) five (5) days after the termination of this
Agreement and (B) sixty (60) days of receipt thereof by TPL.

            (e) The provisions of Article IX, as well as Sections 7.6, 11.1,
11.5, 11.9, 11.13 and 11.14 and this Section 10.2 shall survive any termination
of this Agreement pursuant to this Article X, and each party hereto shall be
fully responsible for any breach of any such provision, whether or not such
breach occurs prior to the termination of this Agreement. In addition, the
parties expressly agree that the Stipulated Final Judgment is severable and has
significance independent of this Agreement and any other agreements and
transactions contemplated hereby and thereby, and as such shall not be affected
or disturbed by the Termination of this Agreement.

      11.8 Captions. The captions herein are included for convenience of
reference only and shall be ignored in the construction or interpretation
hereof. All references to an Article or Section include all subparts thereof.

      11.9 Severability. The failure of any provision of this Agreement by
virtue of its being construed as invalid or otherwise unenforceable shall render
the entire Agreement cancelable at the option of the party asserting the
enforceability of the said provision. Notwithstanding the foregoing, the parties
expressly agree that the Stipulated Final Judgment, Section 11.2(a), Section
11.13 and Section 11.14 are severable and have significance independent of this
Agreement and any other agreements and transactions contemplated hereby and
thereby, and as such shall not be affected or disturbed by the invalidity,
illegality or unenforceability of any such provision or provisions or of the
entirety of any such agreements.

      11.10 Construction. The parties hereto intend that each representation,
warranty and covenant contained herein shall have independent significance. If
any party has beached any representation, warranty or covenant contained herein
in any respect, the fact that there exists another representation, warranty or
covenant relating to the same subject matter (regardless of the relative levels
of specificity) that the party has not breached shall not detract from or
mitigate the fact that the party is in breach of the first representation,
warranty or covenant.

      11.11 Cumulative Remedies. The rights, remedies, powers and privileges
herein provided are cumulative and not exclusive of any rights, remedies, powers
and privileges provided by law.

      11.12 Specific Performance. The parties hereby acknowledge and agree that
the failure of any party to perform its agreements and covenants hereunder,
including its failure to take all actions as are necessary on its part to
consummate the agreements contemplated hereby, will cause irreparable injury to
the other party, for which damages, even if available, will not be an adequate
remedy. Accordingly, each party hereby consents to the issuance of injunctive
relief without bond by any court of competent jurisdiction to compel performance
of such party's obligations and to the granting by any court of the remedy of
specific performance of its obligations hereunder.

      11.13 Third-Party Beneficiaries. Except as specifically provided in (a)
Article IX with respect to indemnification provided to the Indemnitees
identified therein, and (b) Section 11.14, no provision of this Agreement shall
create any third-party beneficiary rights in any Person, including any employee
or former employee of Patriot or any Representative thereof (including any
beneficiary or dependent thereof). Each of Intel and its present, former and
future direct and indirect distributors of Intel Licensed Products
(collectively, the "Intel Parties" ") shall be an express, intended third-party
beneficiary of Section 11.2(a), Section 11.9 and Section 11.14.

      11.14 No Liability of Intel. Upon payment by Intel of all of the unpaid
Milestone Payments provided for at Section 3.2 of the Intel Patent License
Agreement to the account designated at Exhibit A to the Escrow Agreement
attached hereto as Exhibit E, each of Intel and the Intel Parties shall be
forthwith and without further or other action of any kind by anyone, released
from all potential liability with respect to Intel Licensed Products and based
upon the rights of Patriot in and to the Core Patents (as described in the Intel
Patent License Agreement). It is the intention of the parties to this Agreement
in executing this Agreement that the same shall be effective as a bar to each
and every claim, demand and cause of action hereinabove specified in this
Section 11.14. In furtherance of this intention, each of the parties to this
Agreement hereby expressly waives any and all rights and benefits conferred upon
him by the provisions of Section 1542 of the California Civil Code (or any
similar provision of any other applicable law) and expressly consents that this
Agreement shall be given full force and effect according to each and all of its
express terms and provisions, including those related to unknown and unsuspected
claims, demands and causes of action, if any, as well as those related to any
other claims, demands and causes of action hereinabove specified. Section 1542
of the California Civil Code provides:

      "A GENERAL  RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR
      DOES NOT  KNOW OR  SUSPECT  TO EXIST IN HIS OR HER  FAVOR AT THE
      TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST
      HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR."

Each of the parties to this Agreement acknowledges that it or he may hereafter
discover claims or facts in addition to or different from those which it or he
now knows or believes to exist with respect to the subject matter of this
Agreement and which, if known or suspected at the time of executing this
Agreement, may have materially affected this release. Nevertheless, each of the

                                       30
<PAGE>

parties to this Agreement hereby waives any right, claim, or cause of action
that might arise as a result of such different or additional claims or facts.
Each of the parties to this Agreement acknowledges that it or he understands the
significance and consequence of the release set forth in this Section 11.14 and
such specific waiver of Section 1542 (and any other similar provisions of any
other applicable laws).

For the avoidance of doubt, the releases provided for in this Section 11.14
shall extend solely to the use and practice of the Core Patents with respect to
Intel Licensed Products.

      11.15 No Punitive, Exemplary, or Consequential Damages. Except as
expressly set forth herein, the parties hereto understand and agree that under
no circumstances shall punitive, exemplary or consequential damages be available
to any party for breach of this Agreement.

              (a)  Within thirty (30) days after P-Newco's receipt thereof,

the covenants of this Commercialization Agreement, the Master Agreement and the
transactions contemplated hereby and thereby on their respective directors,
officers, employees, consultants, attorneys, agents and other affiliates or
Representatives; and

              (b)  Be responsible hereunder for each and every failure in the

         3.5  With the exception of the agreements and transactions entered into
pursuant to the Project, P-Newco, Patriot and TPL shall not transfer, assign,
license, or otherwise convey any interest in, or grant any security interest
with respect to, any portion of their interest in the MSD Patents during the
term of this Commercialization Agreement without the written consent of all
parties hereto, other than to entities which are owned and controlled by the
transferring Person and who assume and agree to pay and perform all of the
transferor's obligations hereunder.

         3.6  Upon the termination of this Commercialization Agreement, Patriot
shall be entitled to receive a copy of third party "DeCaps" (as such term is
commonly understood to mean in the industry) related to the Commercialization
and third party expert analyses thereof; and TPL does hereby consent to the
deliveries thereof by such third party experts. In the event any of the
foregoing are not provided by such third parties, TPL will provide Patriot with
copies of such documents in its possession. In addition, a Patriot
Representative shall be entitled to view such "DeCaps" on a quarterly basis, but
shall not be entitled to make copies thereof. With the exception of TPL's
obligations pursuant to Section 3.1 and this Section 3.6, TPL shall not be
obligated to share any other materials related to the Commercialization,

purposes shall be deemed to be privileged, proprietary and exclusive to TPL.

         3.7. P-Newco and Patriot shall on a continuing basis provide TPL all

                                   ARTICLE IV
                                     PAYMENT

         4.1  TPL shall cause all Gross Cash Proceeds generated from the

         4.2  Upon the submission of customary and appropriate invoices and

(3) days prior to the start of each fiscal quarter from the Working Capital Fund
to cover indirect and other expenses related to the Project which do not
constitute TPL Direct Reimbursable Expenses ("TPL Other Project Expenses").
Advances to TPL made pursuant to this Section 4.3 shall be nonaccountable and
nonrecoupable, but shall offset the amounts owed TPL pursuant to Section
6.1(a)(iv)(b) of the Operating Agreement in the manner contemplated by such
Section 6.1(a)(iv)(b). At such time as the Working Capital Fund exceeds
$   ***    after the first $   ***     has been generated pursuant to the
Commercialization, such quarterly payment shall be increased (but not decreased)
to one-eighth of the amount of the Working Capital Fund.

<PAGE>

         4.4  To the extent that P-Newco does not have sufficient funds from the
Working Capital Fund at the time any payment is due pursuant to this Article IV,
TPL shall refrain from enforcing any collection rights against P-Newco for such
payments until the earlier of (a) such time as funds become available in the
Working Capital Fund, or (b) termination of this Commercialization Agreement.

                                    ARTICLE V
                                      TERM

         5.1  This Commercialization Agreement shall continue for the useful
life of the MSD Patents, which shall be deemed to be the greater of the period
of time during which any of the MSD Patents is either (i) susceptible to legal
protection, or (ii) reasonably perceived to have commercial value.

         5.2  In the event that facts or events are discovered or occur which
materially reduce TPL's evaluation of the useful life or commercial value of the
MSD Patents, or the viability of the Project, TPL may reduce the term of this
Commercialization Agreement accordingly by providing P-Newco with ninety (90)
days written notice, provided that TPL shall not reduce the term of this
Commercialization Agreement to less than six (6) months.

         5.3  After the expiration of the term provided for above, neither party
shall have any further obligation hereunder other than the administration of all
outstanding transactions as under Article VI below, and the obligations of
confidentiality undertaken by the parties.

                                   ARTICLE VI
                                   TERMINATION

         6.1  TPL may terminate this Commercialization Agreement upon the
failure of Patriot or P-Newco to substantially perform any of their material
obligations to be performed hereunder, including without limitation the payment
obligations pursuant to Article IV of this Commercialization Agreement.

         6.2  P-Newco may terminate this Commercialization Agreement if:

              (a)  TPL has failed to close transactions in accordance with
the Performance Milestones set forth in Section IV of Schedule 2, and

                   (i)   there has been no material breach by Patriot or P-Newco
of this Commercialization Agreement, the Master Agreement, the Newco Licenses or
the Operating Agreement; and

                                       5
<PAGE>

                   (ii)  there has been no event or occurrence which negatively
and materially impacts the viability or value of the MSD Patents; and

                   (iii) the failure of TPL is not reasonably attributable to
the conduct of P-Newco, Patriot and/or their respective affiliates or
Representatives (other than TPL); or

              (b)  TPL enters into a liquidation under Chapter 7 of the
United States Bankruptcy Code; or

              (c)  TPL enters into a reorganization under Chapter 11 of the
United States Bankruptcy Code, and TPL ceases to be a debtor in possession
during the pendency of such bankruptcy proceeding.

         Each of the events referred to in Sections 6.1 and 6.2 shall be
referred to as a "Termination Event". In no event shall the conduct of Moore be
deemed to constitute a Termination Event.

         6.3  Upon termination pursuant to this Article VI:

              (a)  All rights to the MSD Patents arising under the Grant or
this Commercialization Agreement shall be transferred to P-Newco subject to all
outstanding rights under licenses, agreements, or awards theretofore made and
entered into by or with TPL prior to such expiration or termination which, for
all purposes, shall continue and be administered by TPL under TPL's then current
reasonable hourly fee schedule as if this Commercialization Agreement were still
in full force and effect.

              (b)  All amounts due to TPL with respect to TPL Direct Project
Expenses and TPL Other Project Expenses shall be paid from Gross Cash Proceeds
as such funds are received.

              (c)  At the option of Patriot, TPL, or P-Newco, all of the rights
and privileges of whatsoever kind or nature granted by it shall immediately and
without further action whatsoever revert in their entirety to each of Patriot,
TPL, or P-Newco, as the case may be, and all licenses granting such rights and
privileges shall be deemed to be for all purposes cancelled.

              (d)  In the event of a termination by P-Newco or Patriot, all
claims for loss and/or damages shall be deemed to be liquidated and discharged
with respect to each party upon its completion of the dissolution, distributions
and the documentation and transfers contemplated by Article 8 of the Operating
