THEREFORE, Tessera and TI (herein collectively referred to as “Parties” or singularly referred to as “Party”) agree to the following terms:

Page 2 of 18

characteristic, of that particular product, shall not have the effect of reviving TI’s option with respect to that particular product.

B. The term “Patent(s)” means letters patents and utility models and applications therefor in all countries of the world that have issued prior to the expiration of this Agreement, including all such re-issues, re-examinations, continuations, continuations-in-part, divisionals, and all corresponding foreign patents.

D. i. The term “TI” means Texas Instruments Incorporated and all TI Affiliates.

ii. The term “Tessera” means Tessera Incorporated and all Tessera Affiliates.

G. The term “Net Sales Price” means the gross price charged to a third party by TI for Licensed Products sold hereunder, minus goods returned for credit, transportation costs, and direct government charges or taxes, all to the extent separately stated in invoices. Notwithstanding, if (1) TI sells or transfers Licensed Products as a component in a larger sub-assembly to a third party, or (2) TI sells or transfers Licensed Products to a third party for at least partial non-monetary consideration, the “Net Sales Price” for such Licensed Products shall be the average selling price of the most similar Licensed Product TI sold individually to an independent third party in the same fiscal quarter.

II. Grant of Licenses

A. License from Tessera to TI: Subject to the terms and conditions set forth in this Agreement, and as consideration for the Settlement Agreement and this Agreement, Tessera grants to TI, under all Tessera’s Patents, a world-wide, non-exclusive, non-transferable, non-sublicensable license to make, have-made, use, sell, offer for sale, and import Licensed Products. The license to TI, under this Section II.A, for any Licensed Products as to which TI has exercised its option under Section I.A (which do not include Licensed Products sold by TI under the trademark Microstar Jr or Microstar provided that TI continues to pay royalties on such products), may be terminated effective upon written notice by Tessera in the event that TI or any TI Affiliate brings a lawsuit, administrative proceeding (e.g., ITC action), or any other adversarial proceeding against Tessera, or any Tessera customer, based upon a patent claim against any product made by Tessera. Such termination by Tessera shall not affect Tessera’s or TI’s other rights and obligations under this Agreement.

B. Exclusion from License from Tessera to TI: The license set forth in Section II.A from Tessera to TI does not extend to (i) any product which is not a Licensed Product, or (ii) any product for which TI does not pay the royalties prescribed under this Agreement.

C. License from TI to Tessera: Subject to the terms and conditions set forth in this Agreement, and as consideration for the Settlement Agreement and this Agreement, TI grants to Tessera, under TI Patents, a royalty-free, world-wide, non-exclusive, non-transferable, non-sublicensable license to make, have-made (for military products to be used by the United States Government, or for product development purposes, only), use, sell, offer for sale, and import Licensed Products and Face-Down Packages.

Except for any Licensed Products, or Face-Down Packages, which are military products, sold by, or made by or for, Tessera for use by the United States Government (“Military Products”); the license granted to Tessera by TI under this Agreement shall be

Page 5 of 18

extended to a quantity of Licensed Products, and Face-Down Packages, not exceeding [*] ($[*]) per year in gross revenue (or fair market value, whichever is greater) attributable to the total of all such Licensed Products, and Face-Down Packages, other than Military Products, made, sold, offered for sale, used or imported by Tessera during that year (“Annual Cap”). After the Annual Cap has been reached by Tessera, for any given year, any Licensed Products or Face-down Packages manufactured, sold, offered for sale, used, or imported by Tessera in excess of the Annual Cap, shall be unlicensed under this Agreement.

The license to Tessera under this Section II.C may be terminated effective upon written notice by TI in the event that Tessera or any Tessera Affiliate brings a lawsuit, administrative proceeding (e.g., ITC action), or any other adversarial proceeding against TI, or any TI customer, based upon a patent claim against any product manufactured by or for TI. Such termination by TI shall not affect TI’s other rights and obligations under this Agreement.

D. No Implied License. Notwithstanding the foregoing, all licenses under this Agreement are as explicitly set forth in this Agreement, and nothing in this Agreement shall be construed to grant any implied licenses to any party.

III. Fee and Royalty

A. Fee. Within three (3) business days after execution of this Agreement, TI shall pay a one-time, non-refundable license fee of [*] ($[*]).

B. Royalty. TI shall pay royalties, for the licenses granted under this Agreement, four times annually (as set forth in Section V) to Tessera during the Term of this Agreement. Such royalties shall be paid by TI in the amount of [*] ([*]%) of the Net Sales Price for Licensed Products on a worldwide basis for the Term of this Agreement. This royalty rate reflects in part the additional consideration paid

Page 6 of 18

to Tessera in settlement of the pending litigation between the Parties, including the license under Section II.C. For any particular product that becomes a Licensed Product on the exercise of TI’s option in Section I.A, the obligation to pay royalties for that particular product shall commence on the date that TI exercises its option or on the date of commencement of the 60-day negotiation period pursuant to Section VI.D triggered by Tessera’s request to TI to exercise its option to include such particular product as a Licensed product, whichever date is earlier.

IV. Taxes

Payments and royalties due hereunder shall be calculated and paid by TI to Tessera on a “net cash” basis per the terms hereof and shall be free of and not reduced in any way by any imposed taxes or other assessments that may be levied by any government or country.

V. TI Reports and Payment

Beginning on the Effective Date of this Agreement, royalties shall be calculated and paid in full for each quarterly payment period ending March 31, June 30, September 30 and December 31 of each year during the Term of this Agreement.

The payments of royalties and submission of such reports from TI to Tessera under this Section shall be made within sixty (60) days from the end of each

Page 7 of 18

quarterly payment period and shall be considered to be made as of the day on which such payments are received in Tessera’s designated bank account.

A. Term. This Agreement shall become effective on the Effective Date and, unless earlier terminated as provided for elsewhere in this Agreement, shall remain in full force until December 31, 2013. If this Agreement is not earlier terminated as provided for elsewhere in this Agreement, after December 31, 2013 (i) TI shall have a fully paid-up, royalty-free, perpetual, world-wide, non-exclusive, non-transferable, non-sublicensable license, under all Tessera’s Patents (having enforceable rights as of December 31, 2013), to make, have-made, use, sell, offer for sale, and import Licensed Products, to the same extent that TI was licensed on December 31, 2012 and (ii) Tessera shall have a fully paid-up, royalty-free, perpetual, world-wide, non-exclusive, non-transferable, non-sublicensable license, under TI Patents (having enforceable rights as of December 31, 2013), to make, have-made (for military products to be used by the United States Government, or for product development purposes, only), use, sell, offer for sale, and import Licensed Products and Face-Down Packages.

B. Termination for TI Breach. Tessera may terminate this Agreement as to any particular Licensed Product if TI fails to pay the royalties prescribed under this Agreement for such Licensed Product, or if TI fails to submit written reports as required herein, and TI fails to cure any such breach (or mitigate it to Tessera’s satisfaction) within sixty (60) days after receipt of written notice from Tessera. Any such breach shall be deemed by the Parties to be curable within such 60-day period, regardless of when such written notice is given or when such alleged breach occurs.

Page 8 of 18

after receipt of notice from Tessera, regardless of the reason for TI’s failure to pay. Notwithstanding anything in this Agreement to the contrary, this Agreement shall continue in full force and effect as to all Licensed Products for which TI continues to pay royalties.

D. Request to Negotiate. (1) During the Term of this Agreement, neither Party shall bring any litigation against the other Party, or such other Party’s customer, based on any patent or claim related to this Agreement, without first providing such other Party with written notice and engaging in good faith negotiations during a 60-day negotiation period beginning on the date of such written notice. (2) At any time during the Term of this Agreement, with regard to any specific products, either Party shall have the right to engage the other Party in good faith negotiations to include such products under this Agreement as Licensed Products. Any such good faith negotiations shall be concluded within 60 days after written notice from the Party requesting such negotiations, or providing notice of breach, unless both Parties agree in writing to extend the period. Neither Party may commence litigation relating to any such product prior to the expiration of this 60-day period. Unless extended as provided herein, at the expiration of the 60-day period, either Party may commence litigation. Neither Party shall have an obligation to agree to the inclusion of such products. This Section VI.D shall not abridge or modify TI’s option as defined in Section I.A. Neither Party shall have the obligation to agree to any extension of the 60-day negotiation period.
