TESSERA, INC.

Addendum to

TCC Master License Agreement

This Addendum is entered into as of Jan 31, 1997, between TESSERA, INC., a corporation organized under the laws of Delaware (“Tessera”) and HITACHI, LTD., a corporation organized under the laws of Japan (“Licensee”); modifies a certain TCC Master License Agreement (“Agreement”) by and between the parties dated July 7, 1994. Unless otherwise specified, all references to Licensee shall mean the Semiconductor and Integrated Circuits Division of Hitachi, Ltd. Both parties hereby agree as follows:

I. Definitions:

The terms used herein which are defined in the Agreement shall have the same meaning when used herein unless the context hereof shall otherwise require or provide. As used herein, the term “Effective Date” shall mean the date first above written.

II. Amendments to the Agreement:

The Agreement shall be amended as follows:

(1) Article I. U is added to include the definition of the Batch Technology, to read as follows:

U. The term “Batch Technology” as used herein means Technology including: (i) any method or result of U.S. Patent 5,518,964 (and related Patents) for bonding or connecting one or more substantially planar electrically conducting flexible elements to electrical contact(s) on a substantially planar electrical element such as a semiconductor integrated circuit, undiced IC wafer, or interconnect substrate, and then forming said element(s) away from the plane of said contacts in a predetermined fashion into the flexible electrical lead(s) of a TCC package; (ii) any method or result of U.S. Patent 5,455,390 (and related Patents) for making and forming one or more flexible conducting elements on a flexible dielectric film and simultaneously joining said elements to electrical contacts on a substantially planar electrical element such as a semiconductor integrated circuit, undiced IC wafer or interconnect substrate to produce the flexible electrical leads of a TCC package; and/or (iii) any method or result of further invention or Patent made or acquired by Tessera during the term hereof covering any batch processing method for forming or producing and/or connecting flexible electrical leads of a TCC package. Notwithstanding, the parties further expressly agree that any TCC package made and/or connected individually on an IC wafer before dicing by traditional wire bonding methods and/or tape automated bonding (“TAB”) gang bonding methods, is not included in Batch Technology.

(2) Article II. A is amended in its entirety to reflect a change in the Licensee rights, to read as follows:

(4) Article III. B. (iii), (iv), (v) and (vi) are replaced by the following two paragraphs to reflect changed in running royalties to read as follows:

(iii) TCC Royalty. For sales or other transfers of any TCCs (Coarse Pitch, Fine Pitch, or High Performance), whether manufactured for sale or internal use, Licensee shall pay running royalties for the license granted in Paragraph II. A twice annually to Tessera during the term of the Agreement. Said royalty shall be calculated on Licensee’s total unit volume of IC bonds, leads, or equivalent connections made or bonded in TCCs or related IC packages under Tessera Patent. Said royalty shall be paid in the amount of [*] ($[*]) per each bond or connection made to an IC bond pad in said TCC or related IC packages made by or for Licensee hereunder.
