Conformed Copy

SETTLEMENT AGREEMENT

THIS SETTLEMENT AGREEMENT (the “Agreement”) is made by and among Rambus Inc., a Delaware corporation (“Rambus”), on the one hand, and Samsung Electronics Co., Ltd., a corporation organized under the laws of Korea (“Samsung Electronics”), Samsung Electronics America, Inc., a Delaware corporation, Samsung Semiconductor, Inc., a California corporation and Samsung Austin Semiconductor, L.P., a Texas limited partnership (collectively, “Samsung,” with Rambus and Samsung each being a 220;Party” and together the “Parties”), on the other hand, effective as of January 19, 2010 (the “Effective Date”).

WHEREAS, Samsung and its Subsidiaries (as defined in Article 1) are and will continue to be engaged in the manufacture, use, sale and/or importation of various products and devices, including but not limited to memory products and memory interface technologies (collectively, the “Samsung Products”), which utilize diverse and varied technologies;

WHEREAS, Rambus and/or its Subsidiaries have and will continue to have rights under Patents (as defined in Article 1), including but not limited to the right to license such Patents to third parties (collectively, all such patents are the “Rambus Patents”), covering diverse and varied technologies;

WHEREAS, the Parties are currently parties to a number of Disputes (as defined in Article 1) relating to the Samsung Products and the Rambus Patents, including but not limited to disputes as to whether claims of Rambus Patents are infringed by Samsung Products, and disputes relating to the validity, enforceability and use of certain Rambus Patents, and the Antitrust Litigation (as defined in Article 1);

WHEREAS, the Parties acknowledge that the Disputes have been costly, not only in terms of the out-of-pocket costs incurred by each of them, but also in terms of management time and other resources devoted to such efforts;

WHEREAS, the Parties recognize that, without this Agreement, given the diversity of claims of the Rambus Patents, and the breadth of technologies utilized by the Samsung Products, Rambus could, after the Effective Date, assert that other claims of Rambus Patents are infringed by Samsung Products, and that such disputes, if they were to occur would involve similar costs and business disruptions;

WHEREAS, the Parties recognize that litigation of the Disputes, and of other disputes that may arise between them after the Effective Date, is inherently uncertain, and is subject to certain risks, including but not limited to (a) whether the Rambus Patents, including Patents which are known to Samsung but which to date have not been asserted against Samsung, are determined to be valid, enforceable and infringed in various trial and appellate court, Patent and Trademark Office and International Trade Commission proceedings, and (b) whether Rambus prevails in various other court or regulatory proceedings, such as the Antitrust Litigation, and that such events are subject to various possible outcomes;

WHEREAS, the Parties desire to eliminate the risks associated with such litigation and to enter into a comprehensive resolution to compromise, settle and release the Disputes, and to compromise, resolve and avoid other disputes that may arise after the Effective Date with respect to the Samsung Products and the Rambus Patents;

WHEREAS, as part of the comprehensive resolution of other disputes that may arise after the Effective Date with respect to the Samsung Products and the Rambus Patents, Rambus and its Subsidiaries desire to grant Samsung and its Subsidiaries a license to certain of the claims of the Rambus Patents from the Effective Date for a limited term, and to grant Samsung and its Subsidiaries a fully paid-up license for certain of the Samsung Products to certain of the claims of the Rambus Patents, and Samsung and its Subsidiaries desire to grant Rambus and its Subsidiaries a license to certain of the claims of the Samsung Patents;

WHEREAS, the Parties acknowledge that in resolving the Disputes, and other disputes that may arise after the Effective Date, each of them is giving up the possibility of more favorable outcomes in exchange for the promises and covenants it will receive under this Agreement, and the other agreements contemplated hereby, to ensure that they do not ultimately face less favorable outcomes and to avoid the costs, delays and disruptions associated with litigation, and that such promises and covenants represent a package, and are not intended to be severable from each other; in particular, (a) Samsung is receiving a full and final release of the claims asserted against it in the Disputes, and securing a license to claims of the Rambus Patents in exchange for making the license and oth er payments, and entering into the other agreements, described herein, and (b) Rambus is receiving the Comprehensive Resolution Payments (as defined in Article 1), and the benefit of the other agreements described herein, in exchange for granting the releases and licenses, and entering into the other agreements, described herein;

WHEREAS, the Parties acknowledge that it is therefore essential that their respective obligations under this Agreement and the other agreements described herein be certain and not subject to collateral attack, or otherwise subject to change or modification except on the terms expressly set forth therein; and

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

Article 2

Comprehensive Resolution Payments

2.1 Initial Payment. As a condition to the effectiveness of the releases and covenants not to sue set forth in Article 4 and the Parties’ obligations under Section 4.8, Samsung Electronics will, on or before January 22, 2010 pay Rambus the sum of One Hundred Million Dollars (US $100,000,000) and will, on or before the Release Date, pay Rambus the sum of One Hundred Million Dollars (US $100,000,000) (collectively, the “Initial Payment”).

2.2 Allocation of Initial Payment. The Parties agree to allocate the Initial Payment in accordance with the following, which they acknowledge represents a reasonable estimated allocation of the Initial Payment to Rambus’s claims under the Disputes:

(a) [***] shall be deemed to be paid in consideration for [***];

(b) [***] shall be deemed to be paid in consideration for [***]; and

2.3 License Payments. As described more fully in the License Agreement and as an integral part of the overall consideration received by Rambus in respect of its releases and covenants not to sue under Article 4, and its other obligations under the Comprehensive Resolution Agreements, over the next five (5) years Samsung Electronics will pay Rambus aggregate license fees of Five Hundred Million Dollars (US $500,000,000), subject to certain adjustments and conditions as described in the License Agreement (the “License Payments”). In the event that Samsung fails to pay any License Payment (and fails to cure suc h failure within the time period provided for in Section 6.2 of the License Agreement), Samsung will pay to Rambus Five Hundred Million Dollars (US $500,000,000), less the aggregate License Payments previously paid by Samsung and retained by Rambus, as part of the overall consideration received by Rambus under the Comprehensive Resolution Agreements, in order for Rambus to receive the full amount of the overall consideration intended to be received in respect of its releases, covenants not to sue, and other obligations under the Comprehensive Resolution Agreements. Samsung will apply such amounts to the Quarterly Base Payments due under the License Agreement.

2.4 No Refunds. Once made, any Comprehensive Resolution Payment shall not be refunded or refundable to Samsung for any reason except as may be required pursuant to Section 3.3 of the License Agreement. Notwithstanding the foregoing, in case of clerical error with respect to any payment made under the License Agreement, the Parties agree to remedy any such error through proper payment adjustments.

2.5 Currency. All Comprehensive Resolution Payments shall be made in United States dollars.

2.6 Wire Instructions. The Initial Payment shall be made by wire transfer to Rambus as follows:

Rambus Inc. Account: [***]

All other Comprehensive Resolution Payments shall be made in accordance with the terms of the applicable Comprehensive Resolution Agreement.

2.7 Taxes. If the Korean government imposes any withholding tax on any Comprehensive Resolution Payments, such tax shall be borne by Rambus. Samsung agrees, at its reasonable discretion, to assist Rambus in its efforts to minimize Rambus’ tax liability. Samsung shall withhold the amount of any such taxes levied on such payments to Rambus imposed by the Korean government, shall promptly effect payment of the taxes so withheld to the Korean tax office, and Samsung shall send to Rambus the official certificate of such payment in a form reasonably sufficient to enable Rambus to support a claim for a foreign tax credit with respect to any such taxes so withheld.

Article 3

Other Agreements

Concurrent with the execution and delivery of this Agreement, and as an integral part of the overall consideration received by the Parties in respect of their releases, covenants not to sue, and other obligations under the Comprehensive Resolution Agreements, the Parties and/or their Subsidiaries shall enter into or deliver the following agreements or documents. For the avoidance of doubt, the MOU described in Section 3.3 is non-binding to the Parties and, while the existence and execution thereof are an integral part of the overall consideration, the contents therein represent solely the understanding between the Parties regarding certain business and technology collaborations, and the failure to enter into any definitive agreement contemplated thereby shall not constitute failure in the consideration hereunder or under any of the other Comprehensive Resolution Agreements.

3.1 License Agreement. Rambus and Samsung Electronics shall enter into the License Agreement in the form attached hereto as Exhibit A (the “License Agreement”), pursuant to which Rambus shall grant Samsung licenses under Rambus Applicable Patent Claims, and Samsung will grant to Rambus licenses under Samsung Applicable Patent Claims, as defined in the License Agreement, on the terms set forth therein.

(a) The Parties acknowledge that the licenses granted under the License Agreement are in respect of claims under multiple Rambus Patents and multiple Samsung Patents, respectively, so that the Parties’ rights and obligations under the License Agreement, are not dependent upon the validity or enforceability of specific Rambus Patents or specific Samsung Patents, or upon any specific use of such patents permitted under the License Agreement. Specifically, Samsung acknowledges that the License Agreement covers a broad array of Rambus Patent claims, and agrees to make the full amount of the Comprehensive Resolution Payments regardless of whether any of the Rambus Patents is determined not to be infringed by any particular Licensed Product or a court or United States, European, or other patent office determines any Rambus Patent to be invalid or unenforceable in any reexamination, action or other proceeding.

________________

[***] Confidential treatment has been requested for the bracketed portions. The confidential redacted portion has been omitted and filed separately with the Securities and Exchange Commission.

(b) Each Party acknowledge that its assessment of the value of the Disputes and the License Agreement may depend on certain events that may occur, or that may not occur, after the Effective Date, that it is aware of and has evaluated and considered the uncertainties associated with such events, and that it has agreed to the amount of the Comprehensive Resolution Payments to eliminate such uncertainties so that, for example, Samsung will be protected from the consequences of Rambus prevailing on infringement and other claims in other proceedings, and Rambus will be protected from the consequences of certain of the Rambus Patents being held to be invalid, unenforceable, and/or not infringed in other proceedings. It is therefore essential that the Parties’ obl igations under the License Agreement, including but not limited to the amount of the License Payments, be certain and not subject to collateral attack. Accordingly,

(i) Samsung covenants, whether through litigation or otherwise, not to seek to adjust the amount of the License Payments, or to avoid, defer or modify its obligations under the License Agreement, provided that the foregoing shall not prevent Samsung from seeking enforcement of the terms and conditions of the License Agreement or taking any action expressly contemplated in the License Agreement.

(ii) Samsung and its Subsidiaries acknowledge and agree that, for all acts or omissions that occur during the time period up to and including the [***] anniversary of the Effective Date (the “Effective Time Period”), Rambus or its Subsidiaries have patent claims that are valid, enforceable and infringed by a substantial portion of the Licensed Product (as defined under the License Agreement). After the Effective Time Period, Rambus and its Subsidiaries covenant not to rely on such acknowledgement or agreement in any manner against Samsung or its Subsidiaries or their past, present or future distributors or customers in negotiations, and further covenant that no evidence of such acknowledgement or agreement may be in troduced in any negotiation by or on behalf of Rambus or its Subsidiaries against Samsung or its Subsidiaries or their past, present or future distributors or customers. Rambus and its Subsidiaries further covenant, with respect to any acts or omissions occurring after the Effective Time Period, not to rely on such acknowledgement or agreement in any manner against Samsung or its Subsidiaries or their past, present or future distributors or customers before any court, government agencies, other regulatory body or arbitrator, and further covenant that no evidence of such acknowledgement or agreement may be introduced in any motion, hearing, trial or other proceeding by or on behalf of Rambus or its Subsidiaries against Samsung or its Subsidiaries or their past, present or future distributors or customers.

3.2 Stock Purchase Agreement. Rambus and Samsung Electronics shall enter into the Stock Purchase Agreement in the form attached hereto as Exhibit B (the “Stock Purchase Agreement”). Concurrent with the execution and delivery of the Stock Purchase Agreement, Rambus and Samsung Electronics shall complete the equity investment in Rambus in accordance with the terms thereof.

3.3 Memorandum of Understanding. Samsung Electronics and Rambus shall enter into a Memorandum of Understanding in the form attached hereto as Exhibit C (the “MOU”).

9.5 No Assignment. This Agreement is personal to the Parties, and the Agreement and/or any right or obligation hereunder is not assignable, whether in conjunction with a change in ownership, merger, acquisition, the sale or transfer of all, or substantially all or any part of either Party’s or any of their respective Subsidiaries’ business or assets or otherwise, voluntarily, by operation of law, reverse triangular merger or otherwise, without the prior written consent of the other Party, which consent may be withheld at the sole discretion of such other Party.

For purposes of the foregoing, a Change of Control” means a transaction or a series of related transactions in which (a) one or more Third Parties who did not previously Control a Party obtain Control of such Party, or (b) the subject Party merges with or transfers substantially all of its assets to a Third Party where the shareholders of the assigning Party, immediately before the transaction or series of related transactions, own less than a fifty percent (50%) interest in the ac quiring or surviving entity immediately after the transaction or series of related transactions.

Each Party confirms that it and its respective counsel have reviewed, negotiated and adopted this Agreement as the agreement and understanding of the Parties hereto and the language used in this Agreement shall be deemed to be the language chosen by the Parties hereto to express their mutual intent. 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.

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

9.8 No Third Party Beneficiaries. Unless otherwise expressly stated herein, nothing in this Agreement, express or implied, is intended to confer upon any person other than the Parties hereto or their respective permitted assignees, successors in interest, and Subsidiaries any rights or remedies under or by reason of this Agreement. The former and current directors, officers, employees, and attorneys of the Parties and their Subsidiaries are intended beneficiaries of Sections 4.1, 4.2, 4.4, 4.5, 4.6 and 4.7.

9.9 Severability. If any provision of any Comprehensive Resolution 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 to effectuate the intent and purpose of the Parties with respect to such invalid or unenforceable provision, and if no feasible interpretation shall save such provision, (a) a suitable and equitable provision shall be substituted therefor in order to effectuate, so far as may be valid and enforceable, the intent and purpose of the Parties with respect to such invalid or unenforceable pr ovision, and (b) the remainder of such Comprehensive Resolution Agreement shall remain in full force and effect.

The failure of either Party to enforce, at any time, any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions, and shall not be deemed in any way to affect the validity of this Agreement or any part thereof, or the right of either Party to later enforce each and every such provision.

Each Party may rely on facsimile or .pdf signature pages as if such facsimile or .pdf pages were originals.

9.12 Further Actions. Each of the Parties hereto agrees to take and cause its Subsidiaries to take any and all actions reasonably necessary in order to effectuate the intent, and to carry out the provisions, of this Agreement.

9.13 Public Disclosures and Confidentiality. The Parties shall issue a press release with respect to the Comprehensive Resolution Agreement in a mutually acceptable form. Each Party agrees that, after the issuance of such press release, each Party shall be entitled to disclose the general nature of this Agreement, but that the terms and conditions of this Agreement, to the extent not already disclosed pursuant to such press release, shall be treated as confidential information and that neither Party will disclose such terms or conditions to any Third Party without the prior written consent of the other Party, provided, however, that each Party may disclose the terms and conditions of this Agree ment:

(h) in confidence, in connection with an actual or prospective merger or acquisition or similar transaction.

In addition, upon execution of this Agreement, or thereafter, Rambus, in its discretion, shall be entitled to file a copy of this Agreement with the U.S. Securities and Exchange Commission, so long as Rambus seeks confidential treatment of such agreement to the extent reasonably possible.
