2.6

No Implied Licenses. The parties agree that except as expressly granted in this Agreement, there are no patent or other intellectual property licenses or rights granted or arising hereunder to either party or to any third party, expressly, by implication, estoppel, or under any other legal theory.

ARTICLE 3

License Request

3.1		Upon request of Infineon, Infineon and its Affiliates shall be entitled to obtain and Rambus shall grant an additional license of the same scope as per Section 2.4, at the then applicable most favored licensee terms and conditions.

4.3		Releases Shall Remain Effective. Each of Rambus and Infineon acknowledges that, after entering into this Agreement, they may discover facts different from, or in addition to, those they now believe to be true with respect to the conduct of the other party.

	(a)		Concurrent with the execution of this Agreement, Infineon, its respective Affiliates, and Rambus, shall execute stipulations and orders for the dismissal with prejudice of all claims and counterclaims against one another and between Rambus and Siemens in The Richmond Patent Litigation, the California Patent Litigation and the California Anti-trust Litigation in the form attached hereto as Exhibit 4.5.

	(b)		Rambus shall within ten (10) business days of the Effective Date, file a motion to withdraw with prejudice any of its infringement claims against Infineon and its Affiliates pending at the Federal Court of Mannheim (Landgericht Mannheim), Germany. Likewise, within ten (10) business days of the Effective Date, Infineon shall file a motion to withdraw with prejudice all its office actions pending at the German and European Patent offices and or patent courts against any of the Licensed Rambus Patents. To the extent a withdrawal of an action is not possible, Infineon shall within ten (10) business days of the Effective Date inform the respective patent office or patent court that Infineon does no longer actively pursue such action.

4.6		Costs and Attorneys’ Fees.

		For the infringement claims pending at the Federal Court of Mannheim (Landgericht Mannheim), Germany, and the case of the utility model (Gbm 9117296U1) Rambus shall bear the responsibility for and pay the court fees, and in case of the utility model, the court and patent office fees.

		For all cases, the parties agree that each will pay its respective attorneys’ fees.

Rambus and its Affiliates agree that they shall not contest in any proceeding the validity, scope, or enforceability of any of the Infineon Patents or any claim

thereof except to the extent that Infineon assert any claim of infringement of any such patent against Rambus or its Affiliates.

ARTICLE 5

Term

5.1		Term. The term of this Agreement shall be from the Effective Date until the expiration of the last to expire of the Licensed Rambus Patents. Neither party may terminate this Agreement for any reason prior to its expiration. This Agreement is based upon an assumption shared by both parties that in the Richmond Patent Litigation there have been no substantive findings or judgments (related to any claims or defenses of the parties) entered since the completion of trial and prior to filing the stipulation of dismissal referenced herein, other than any findings or judgments either reflected in the docket printout attached hereto as Exhibit 5.1, or known by the parties (e.g. due to their inquiry with the Court and Clerk’s Office prior to filing the stipulation of dismissal). If this assumption proves to be incorrect, either or both of the parties understand that they may move pursuant to Rule 60 of the Federal Rules of Civil Procedure for relief from any judgment or stipulation dismissing the case with prejudice, and to the extent that the motion is granted and has the effect of returning the case to its state just prior to the filing of the stipulation of dismissal, then this Agreement shall be null and void.

5.2		Survival. The provisions of Articles 1, 3, 4, 5, 7, 9, 10 and 12 shall survive expiration of this Agreement.

ARTICLE 6

6.1		Notification of Qualifying License Agreements. Within thirty (30) days of each date on which a Leading Supplier becomes or ceases to be subject to a Qualifying License Agreement, Rambus shall notify Infineon of the existence of such Qualifying License Agreement, provided that Rambus’ failure to provide such notice in a timely fashion shall not constitute a breach of this Agreement.

6.2		Payments to First Cap. Subject to Section 6.5, Infineon shall pay Rambus for each calendar quarter starting October 1, 2005 an amount of five million and eight hundred fifty thousand U.S. dollars (US $5,850,000), up to a cumulative amount not exceeding fifty million U.S. dollars (US $50,000,000) (the “First Cap”).

6.3		Payments to Second Cap.

6.5		Cessation of Payment Obligations. Except as set forth in Sections 6.3 and 6.4, and subject to Sections 9.1 and 9.4, Infineon shall have no further obligation to make, and may elect at any time to discontinue making, payments under this Agreement once payments by Infineon to Rambus under this Agreement have reached a cumulative aggregate amount equal to the respective applicable cap as per Sections 6.2, 6.3 or 6.4 and Infineon shall in no event have any obligation to pay a cumulative aggregate amount exceeding one hundred fifty million U.S. dollars (US $150,000,000).

	(c)		In the event that one or more Leading Supplier(s) (or all or substantially all of its [***] business and/or assets) is acquired by an entity that is a Leading Supplier, such acquiring entity shall be deemed to constitute either two (2) Leading Suppliers (in the event of the

		acquisition of a single other Leading Supplier) or three (3) Leading Suppliers (in the event of the acquisition of both other Leading Suppliers).

(d)		In the event that a Leading Supplier acquires rights under this Agreement pursuant to Sections 9.1 or 9.4, such Leading Supplier or the resulting entity, as applicable, shall be deemed to be a Leading Supplier and this Agreement shall be deemed a Qualifying License Agreement.

Neither party shall be considered to be the drafter of this Agreement or any of its provisions for the purpose of any statute, case law, or rule of interpretation or construction that would, or might cause, any provision to be construed against such party.

Successors and Assigns. This Agreement shall benefit, and be binding upon, the parties hereto and their respective permitted assignees, successors in interest, parents, and Affiliates.

Authority. Each party represents that it is fully authorized to enter into the terms and conditions of, and to execute, this Agreement.

Severability. If any provision of this Agreement is held to be invalid or unenforceable, the meaning of such provision shall be construed, to the extent feasible, so as to render the provision enforceable, and if no feasible interpretation shall save such provision, it shall be severed from the remainder of this Agreement, which shall remain in full force and effect. If any provision is so severed, Rambus and Siemens shall use their respective best efforts to negotiate, in good faith, a substitute, valid and enforceable provision or agreement, that most nearly effects the parties’ intent in entering into this Agreement.
