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.

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.

(a) Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by all parties hereto, or in the case of a waiver, by the party against whom the waiver is to be effective; provided, however, that any amendment or waiver to Section 11.9, Section 11.13, Section 11.14 or this Section 11.12(a) or any other amendment or waiver with respect to this Agreement of the agreements referenced herein that adversely affects Intel shall be effective only if such written amendment or waiver also has been executed and delivered by Intel.

(b) No waiver by a party of any default, misrepresentation or breach of warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent occurrence. No failure or delay by a party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

11.3 Expenses. All costs and expenses incurred in connection with this Agreement and in closing and carrying out the transactions contemplated hereby shall be paid by the party incurring such cost or expense.

11.4 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. No party hereto may assign either this Agreement or any of its rights, interests or obligations hereunder without the prior written approval of the other party.

11.5 Governing Law. This Agreement shall be construed in accordance with and governed by the internal laws (without reference to choice or conflict of laws) of the State of California.

11.6 Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts and the signatures delivered by fax or other similar means, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by the other parties hereto.

11.7 Entire Agreement. This Agreement (including the Schedules and Exhibits referred to herein which are hereby incorporated by reference and the other agreements executed simultaneously herewith) constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings and negotiations, both written and oral, between the parties with respect to the subject matter 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 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.

6. Liabilities and Duties of Escrow Agent.

PATENT LICENSE AGREEMENT

This PATENT LICENSE AGREEMENT (“Agreement”) is entered into by and between PATRIOT SCIENTIFIC CORPORATION, a Delaware corporation (“Licensor”) having its principal place of business at 10989 Via Frontera, San Diego, California 92127, and INTEL CORPORATION, a Delaware corporation, located at 2200 Mission College Blvd., Santa Clara, CA 95052 (“Intel”).

RECITALS

WHEREAS, TPL Micro Ltd. Technology Properties Limited, and Charles H. Moore (the “Moore Parties”) entered into the attached Patent License Agreement with Intel dated June 28, 2004 (“Intel PLA”); and,

WHEREAS, Licensor and the Moore Parties have agreed to resolve the ownership dispute between them; and

WHEREAS, Licensor, Intel, and the Moore Parties desire to eliminate all of Intel’s potential liability with respect to all of Licenser’s rights, title and interest in all of the Core Patents; and

WHEREAS, Licensor and the Moore Parties desire to cause all unpaid Milestone Payments set forth in Section 3.2 of the Intel PLA to become immediately due and payable.

NOW, THEREFORE, in consideration of the promises and the mutual promises and covenants contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

DEFINITIONS

Capitalized terms used in this Agreement that are not otherwise defined herein shall have the meaning assigned to them in the Intel PLA. For the avoidance of doubt, the term “License” in this Agreement shall refer to Patriot Scientific Corporation.

Article 1. License Grant

1.1 Subject to the terms and conditions of this Agreement, Licensor hereby grants to Licensee a non-exclusive, perpetual, non-transferable, irrevocable, non-terminable, paid-up, royalty-free, worldwide license under the Patents to make, have made, use, lease, license, export, import, distribute, offer for sale and sell any Intel Licensed Products, and to practice, in the course of exercising any or all of the above rights as to Intel Licensed Products, any process which absent a license would infringe such Patents. The Licenses granted hereunder to Licensee shall be deemed to include all Patents which were filed prior to January 1, 2002 in which Licenser has any rights to grant a license.

1.2 Right to License. In the event Licensor does not have the right to grant a license under any particular patent right of the scope set forth herein, then the license granted herein under such patent right shall be of the broadest scope which Licensor has the right to grant. If Licensor

(a) owns any rights in any Patent; or

(b) has the right to enforce or control the enforcement of any rights in any Patent; or

(c) can exercise any significant influence over the enforcement of any rights in any Patent but Licenser does not have the right to license those rights as broadly as set forth in Section 1.1 to Licensee hereunder (“Restricted Patent Rights”), then, if and to the extent that such Restricted Patent Rights would have been licensed to the Licensee if Licensor had the right to license such Patents;

(d) Licenser grants to the Licensee for Intel Licensed Products an immunity from suit for infringement of such Restricted Patent Rights of a scope identical to the rights that would have been granted hereunder if Licensor has the right to license such Restricted Patent Rights;

(e) Licensor shall not give their assent irrespective of whether that assent is required to allow a third party entity to assert the Restricted Patent Rights against the Licensed Products of the Licensee; and

(f) Licensor agrees to indemnify arid hold harmless Licensee against any monetary compensation, including those for damages and/or royalties, paid or to be paid by Licensee as a result of actual or threatened assertion of rights by the holder of the Restricted Patent Rights against Intel Licensed Products to the extent attributable to such Restricted Patent Rights, but only to the extent that such damage and/or royalty, directly or indirectly, benefits Licenser.

1.3 Further Assurances. To the extent Licenser does not have the right to grant any or all of the license rights granted in Section 1 of this Agreement or to the extent this Agreement does not grant such license rights, Licenser hereby grants such licenses to the fullest extent of their rights under the Patents and to the fullest extent possible under the law, and shall execute whatever documents are necessary to effectuate such license grant.

1.4 “Patents” shall mean all of the patents and patent applications listed on Appendix 1, and any patent, patent application or patent right throughout the Territory including, without limitation, any provisional, divisional, continuation, continuation-in-part, substitute, renewal, reissue, extension, confirmation, reexamination or registration thereof and any patent issuing therefrom including any substitute, renewal, reissue, extension, confirmation, reexamination or registration thereof

Article 2. Effective Date of License Grants.

2.1. The effective date of the license grant to each individual Patent licensed to Intel hereunder shall be the filing date of such Patent.

Article 3. Consideration.

3.1 As full consideration for the rights granted by Licensor to Licensee in Article I hereunder, and notwithstanding any rights Intel may have under the Intel PLA. Intel hereby agrees that the Milestone Payments provided for under Section 32.(c) of the Intel PLA and totaling Twenty Million Dollars ($20,000,000) shall become immediately due and payable upon the execution of this Agreement by both parties. Licensor hereby acknowledges the adequacy of this consideration paid by Licensee to Licensor in consideration for the rights granted by Licensor in Article 1 hereunder, including without limitation the acceleration of payment of money from TPL Micro Ltd. to Licensor as a direct result of the acceleration of payment of the Milestone Payments by Licensee to TPL Micro Ltd.

3.2 The payment of the Milestone Payments to TPL Micro Ltd. by Licensee pursuant to this Article 3 shall be made within five (5) business clays after Intel receives Notice of the triggering event by wire transfer to:

Article 4. Other Intel PLA Provisions

4.1 All provisions of Articles 4 through Article 9 are hereby incorporated herein by this reference, provided only that

4.3 By Licenser: Li censor represents and warrants that to the best of its information and belief, Licenser (or its predecessor in interest) is the inventor or co-inventor of all inventive or patentable subject matter that has arisen or will arise from U.S. Patent Application No. 389,334 filed on August 3, 1989 entitled High Performance, Low Cost Microprocessor Architecture” (including any related portion of SN’ 263) including without limitation the disclosed subject matter of those patents identified in Appendix I to the Patent License Agreement between TPL Micro Ltd., Technology Properties Limited, Charles H. Moore and Intel Corporation, dated, June 28, 2004, including, but not limited to, the subject matters of variable speed clocking, multiple instruction fetch, and load dependent bus timing.

; and

(d) Section 9.18 shall be deleted in its entirety and replaced with the following:

“Most Favored” Licensee. Except as required with respect to the licenses granted to NewCo and to TPL in conjunction with the transactions contemplated by the Master Agreement, in the event that Licensor subsequently enters into a license with a third party (the “Third Party Licensee”) for the Patents, or any portion of the Patents, on terms which are in the aggregate and comparatively less favorable to Licensor or more favorable to Licensee than the terms upon which the Moore Parties licensed the Patents to Licensee pursuant to the Intel PLA, then Licenser shall pay to Licensee the difference between (i) the consideration paid by Licensee to TPL Micro Ltd. for its license under the Patents pursuant to the Intel PLA, and (ii) the amount paid by the Third Party Licensee for its license under the Patents or any portion of the Patents. At Licensee’s request, Licensor shall make available for review by Licensee all licenses under the Patents.

Article 5. Litigation

As soon as practicable after the execution hereof, the parties shall promptly arrange for the dismissal of the litigation currently pending between the parties in Oakland.

IN WITNESS WHEREOF, the parties hereto have executed and delivered this Agreement as of the date first above written.
