hereby irrevocably releases, acquits, forever discharges and covenants not to
sue the other party, its Subsidiaries, and its and their distributors,
customers, mediate and immediate, from any and all claims of infringement
(direct, induced, indirect, or contributory) of any Patents for acts prior to
the Effective Date which, if occurring after the Effective Date, would be
licensed hereunder, or would be subject to paragraph (B) of Section 3. If a
company becomes a Subsidiary of a party after the Effective Date of this
Agreement, and (A) that company is then in litigation, arbitration, before the
International Trade Commission, or any other proceeding in which it has asserted
any claims against the other party, and (B) claims asserted against such other
company by the other party would be released, pursuant to this section, upon the
company's becoming a Subsidiary, then, as a condition of such company's
obtaining the benefits of this Section 2.1(a) as a Subsidiary, it shall
irrevocably release the other party, for no additional consideration, from all
such claims. This Section 2.1(a) shall not apply to any acts, prior to the
Effective Date, of any successor in interest of either party. For the avoidance
of doubt, a party's distributors and customers, mediate and immediate ("Released
Customers") are so released from such claims of infringement only with respect
to their use, import, offer for sale, or sale of Intel Licensed Products
acquired, directly or indirectly, from Intel or its Subsidiaries.

                  (b)   In addition, each party releases, acquits, and
discharges the other party and its Subsidiaries which are Subsidiaries as of the
Effective Date of this Agreement, from any and all claims and/or liabilities of
any nature or kind, whether known or unknown, as of the Effective Date, relating
to or arising out of the subject matter of this Agreement or the 1996 Agreement
as Amended. UPON THE ADVICE OF LEGAL COUNSEL, EACH PARTY AND ITS SUBSIDIARIES
WAIVE AGAINST THE OTHER PARTY AND ITS SUBSIDIARIES, ALL RIGHTS UNDER CALIFORNIA
CIVIL CODE SECTION 1542 AND ANY OTHER STATE OR FEDERAL STATUTE OR COMMON LAW
PRINCIPLE OF SIMILAR EFFECT. SECTION 1542 PROVIDES: A GENERAL RELEASE DOES NOT
EXTEND TO CLAIMS

                                       - 5 -

<PAGE>

WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF
EXECUTING THE RELEASE, WHICH, IF KNOWN BY HIM, MUST HAVE MATERIALLY AFFECTED HIS
SETTLEMENT WITH THE DEBTOR.

      3. Rambus License to Intel. Subject to the terms and conditions of this
Agreement, Rambus, on behalf of itself and its Subsidiaries, grants to Intel and
its Subsidiaries a worldwide, nonexclusive, nontransferable license, without
right of sublicense, under Rambus Patents to:

                        (i)   make, have made (subject to the restrictions of
Section 6.1), use, and import, and sell, offer to sell and otherwise dispose of
Intel Licensed Products (subject to Section 6.2); and

                        (ii)  make, have made (subject to the restrictions of
Section 6.1), use, offer to sell, sell and/or import any equipment and practice
any method or process for use in the manufacture, sale, offer for sale, or
import of Intel Licensed Products.

For purposes of this Section 3, an "Unlicensed IC" shall mean an Integrated
Circuit the manufacture, use, import, or sale of which by a third party is
unlicensed by Rambus. With respect to each Unlicensed IC acquired by Intel or
its Subsidiaries from a third party and incorporated by Intel into an Intel
Licensed Product, due to the licenses granted herein:

                  (A)   Rambus shall retain all of its rights against such third
parties, and no license, covenant not to sue, or other right or benefit shall be
implied on behalf of said third party with respect to the Unlicensed IC.

                  (B)   The Unlicensed IC is expressly excluded from the scope
of Intel's and its Subsidiaries' license (express, implied, or otherwise), but
Rambus hereby agrees that it cannot assert any claim against Intel, its
Subsidiaries, or their distributors or customers, mediate or immediate, with
respect to any such entity's use, importation, offer for sale, or sale of such
Unlicensed IC if purchased from Intel as part of an Intel Licensed Product.

                  (C)   If however, Intel or its Subsidiaries incorporate such
Unlicensed IC into a product that is an Intel Licensed Product, Rambus hereby
agrees it cannot assert any claim against Intel, its Subsidiaries, or their
distributors or customers, mediate or immediate, with respect to any such
entity's use, importation, offer for sale, or sale of such Unlicensed IC.

      4.    Intel License to Rambus.

            4.1   Memory Interfaces. Subject to the terms and conditions of this
                  -----------------
Agreement, Intel, on behalf of itself and its Subsidiaries, grants to Rambus and
its Subsidiaries a worldwide, royalty free, nonexclusive license, under Intel
Patents pertaining to Memory Interfaces, to design, make, have made (subject to
Section 6.1), use, import, offer to sell, and sell or otherwise dispose of any
Compliant Portions of Memory Interfaces (alone or as incorporated into products)
(subject to Section 6.2) provided that such license does not extend to any part
or function of a product in which a Compliant Portion is incorporated that is
not itself part of the Compliant Portion. Rambus shall

                                       - 6 -

<PAGE>

have the right to sublicense (without any right of its sublicensees to further
sublicense except to their Subsidiaries) its rights under the Intel Patents to
Rambus Licensees but only to the same scope as Rambus has licensed its
intellectual property (other than trademarks) necessary to implement such Memory
Interface.

            4.2   Rambus shall have the right to obtain [*] as set forth in
Exhibit B. This Section 4.2, however, shall not survive any assignment, merger
in which Rambus is not the surviving entity, or Change of Control of Rambus
without Intel's express written consent.

            4.3   Other Interfaces. Subject to the terms and conditions of this
                  ----------------
Agreement, Intel, on behalf of itself and its Subsidiaries, grants to Rambus and
its Subsidiaries a worldwide, royalty free, nonexclusive license, under Intel
Patents pertaining to Other Interfaces, to design, make, have made (subject to
Section 6.1), use, import, offer to sell, and sell or otherwise dispose of
Compliant Portions of Other Interfaces (alone or as incorporated into products)
(subject to Section 6.2), provided that such license does not extend to any
portion of a product in which a Compliant Portion is incorporated other than
such Compliant Portion. Rambus shall have the right to sublicense (without any
right of its sublicensees to further sublicense except to their Subsidiaries)
its rights under the Intel Patents to Rambus Licensees but only to the same
extent Rambus has licensed such Rambus Licensee under Rambus' and its
Subsidiaries' intellectual property rights (other than trademarks) necessary to
implement the Other Interface, provided that such sublicense shall exclude use
of the Compliant Portion in products other than Rambus Licensed Integrated
Circuits.

            4.4   In response to a written request from Intel, Rambus will
respond within thirty (30) days whether the company named in the request has an
Interface license from Rambus, subject to Rambus' confidentiality obligations,
if any, to such company. Each party agrees to treat all information provided to
the other party under this Section 4.4 as Confidential Information of the
disclosing party pursuant to a Corporate Non-disclosure Agreement between the
parties.

      5.    Licenses for Subsidiaries.

            5.1   Intention for Subsidiaries to be Bound.

                  (a)   Except as expressly set forth herein, the parties intend
that this Agreement shall extend to all of each party's Subsidiaries. The
parties agree that to the extent they are not already bound, each party shall
use reasonable and diligent efforts to ensure that all such Subsidiaries are
bound by the terms of this Agreement.

                  (b)   Each party agrees to take all steps that are reasonable
and in good faith under the circumstances to ensure that all Patents directed to
inventions that are made by its employees and/or contractors either alone or in
conjunction with the employees and/or contractors of one or more of its
Subsidiaries or third parties (to the extent legally possible) are licensed
under this Agreement. Each party further agrees to take all steps that are
reasonable and in good faith under the circumstances to ensure that all Patents
directed to inventions that are made in substantial part using funding provided
directly or indirectly by that party and/or its Subsidiaries are licensed under
this Agreement.

                                       - 7 -

<PAGE>

                  (c)   Notwithstanding the foregoing, however, both parties
understand and intend that there are circumstances in which a party could
reasonably agree in good faith with an independent third party that the party
would not have rights to license and/or enforce Patents directed to inventions
developed in conjunction with employees and or contractors of such third party.
For example, both parties understand that it could be reasonable under the
circumstances for a party to agree in good faith not to have rights to license
and/or enforce Patents directed to inventions that arise out of: (i) bona fide
joint development projects based in substantial part on the pre-existing
technology of an independent third party; or (ii) bona fide joint development
projects undertaken with the significant assistance of the employees and/or
contractors of an independent third party.

                  (d)   Either party to this Agreement shall have the right to
request a written confirmation or denial from the other party to this Agreement
that a specific Subsidiary is (or is not) bound by this Agreement. A party
receiving such a request shall provide such written confirmation (including a
full explanation in support of such confirmation or denial) within 30 days after
the receipt of the request.

                  (e)   In the event that neither a party nor any of its
Subsidiaries has 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
shall be of the broadest scope which the licensing party or any of its
Subsidiaries has the right to grant.

                  (f)   The parties represent, warrant and covenant that they
shall not participate in the creation or acquisition of Subsidiaries where a
primary purpose of such creation is to extend the benefits of this Agreement to
a third party.

                  (g)   The extension of license rights to a Subsidiary shall
apply only during the time period when such Subsidiary meets all requirements of
a Subsidiary. However, if a Subsidiary of a party that holds any Patents that
are licensed to the other party hereunder ceases to meet all requirements of
being a Subsidiary, the licenses granted by such Subsidiary to the other party
under this Agreement shall continue for the life of such Patents even after such
entity ceases to meet all the requirements of being a Subsidiary.

      6.    Limitations on Licenses.

            6.1   Have Made Rights.

                  (a)   Each party's and its sublicensee's rights to have
products manufactured for it by third parties under the licenses and sublicenses
granted under Sections 3 and 4 above shall apply only when the designs,
specifications and working drawings for the manufacture of such products to be
manufactured by such third party are furnished to the third party manufacturer
by the party licensed under this Agreement ("Licensed Party").

                  (b)   The parties understand and acknowledge that Intel's
Licensed Products may consist of software, and that software is often
distributed to end users by providing a single master copy of such software to a
distributor, replicator, VAR, OEM or other agent and authorizing

                                       - 8 -

<PAGE>

such agent to reproduce such software in substantially identical form.
Accordingly, the parties agree that the licenses granted in Sections 3 and 4 are
intended to apply to the reproduction and subsequent distribution of such
software Licensed Products in substantially identical form by such authorized
agent.

                  (c)   Upon written request of the party to this Agreement that
grants the relevant license to the Licensed Party ("Requesting Party"), the
Licensed Party shall, within 30 days of receiving such request, inform the
Requesting Party in writing whether, and if so to what extent, any manufacturer
identified by the Requesting Party is manufacturing any product for the Licensed
Party pursuant to the "have made" rights granted under this Agreement.

                  (d)   To the extent that Intel acts a foundry for third
parties (i.e., by providing manufacturing services for a third party for such
third party's Integrated Circuit products), Intel shall be licensed pursuant to
this Agreement under any Rambus Patents on semiconductor manufacturing processes
or methods.

            6.2   Clarification Regarding Patent Laundering. The parties
                  -----------------------------------------
understand and acknowledge that the licenses granted hereunder are intended to
cover only the products of the two parties to this Agreement and their permitted
sublicensees, and are not intended to cover manufacturing activities that either
party or a sublicensee may undertake on behalf of third parties (patent
laundering activities). Similarly, the licenses provided under this Agreement
are not intended to cover services provided by the parties or their sublicensees
to the extent that such services are provided to or on behalf of a third party
using tangible or intangible materials provided by or on behalf of the third
party. Accordingly, by way of clarification, the following guidelines are
provided to aid the determination of whether a party's or its sublicensees
product is licensed as provided herein or whether such product is disqualified
from being licensed because circumstances surrounding the manufacture of the
product suggest patent laundering.

                  (a)   Products that would be licensed (including, without
limitation, Application Specific Integrated Circuits "ASICs") are disqualified
as licensed products if such products are manufactured on behalf of a third
party from designs received in a substantially completed form from a third party
for resale to or on behalf of that party.

                  (b)   Products (including, without limitation, ASICs) that
would be licensed are not disqualified as licensed products under the
prohibition against patent laundering set forth in this Section 6.2 if:

                        (i)   the party selling such product owns the design of
such product and is under no obligation that restricts the sale of such product;
or

                        (ii)  the party selling such product has an
unrestricted, royalty-free ownership or license right to the design of such
product.

Further, it is understood that Rambus and/or its Subsidiaries have granted, and
may in the future grant, to Rambus Licensees the right to incorporate Interfaces
into such Rambus Licensee's ASIC

                                       - 9 -

<PAGE>

products, and it is agreed that such ASIC products, of Rambus, its Subsidiaries,
and/or Rambus Licensees, are not disqualified as licensed products under the
prohibition on patent laundering in this Section 6.2.

      7.    Waiver of Indirect Infringement Liability.

            7.1   For purposes of this Section 7, "Indirect Infringement" means
a claim for infringement where the accused infringer is not directly infringing
the subject patent rights(s), but is in some manner contributing to a third
party's direct infringement of the subject patent rights(s) by, for example,
supplying parts or instructions to the third party that as a result of such
parts or instructions enable such third party to infringe directly the subject
patent rights(s). Indirect Infringement includes without limitation contributory
infringement and inducing infringement.

            7.2   Each party agrees that, unless the licenses it has granted
hereunder are terminated pursuant to Section 18, for any of its Patents, it and
its Subsidiaries will not assert a claim of Indirect Infringement against the
other party or its Subsidiaries licensed hereunder. The parties agree that the
foregoing sentence does not and shall not in any way limit their respective
rights to assert direct or indirect claims of infringement against third
parties.

      8.    Limitations. No license or other right is granted, by implication,
estoppel or otherwise, to either party under any patents, confidential
information or other intellectual property rights now or hereafter owned or
controlled by either party except for the licenses and rights expressly granted
in this Agreement. Except as described in Sections 4 and 5, nothing in the
licenses granted hereunder or otherwise contained in this Agreement shall
expressly or by implication, estoppel or otherwise give either party any right
to license the other party's Patents to third parties. Nothing contained in this
Agreement shall be construed as:

            8.1   a warranty or representation by either party, as to the
validity, enforceability, and/or scope of any Patents; or

            8.2   imposing upon either party any obligation to institute any
suit or action for infringement of any Patents, or to defend any suit or action
brought by a third party which challenges or concerns the validity,
enforceability or scope of any Patents; or

            8.3   imposing on either party any obligation to file any patent
application or other intellectual property right application or registration or
to secure or maintain in force a Patent; or

            8.4   a warranty or representation by either party as to the
performance, operation or maintenance of any product of such party or, in the
case of Rambus, its sublicensees, manufactured, used or sold pursuant to this
Agreement; or.

            8.5   an obligation by either party to furnish any engineering
support, technical information, or know-how under this Agreement.

      9.    Warranty Disclaimer.

                                       - 10 -

<PAGE>

            ANY PATENTS OF EITHER PARTY, AND ANY CONFIDENTIAL INFORMATION OF
EITHER PARTY ARE PROVIDED AND/OR LICENSED "AS IS" WITHOUT WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

      10.   Indemnification.

            10.1  Rambus disclaims and shall have no obligation of defense,
contribution, or indemnity with respect to any actual or alleged intellectual
property infringement with respect to Rambus intellectual property rights or
otherwise arising out of this Agreement. Rambus shall have no liability arising
out of any such actual or alleged intellectual property infringement. Rambus
shall have no obligation to intervene in any such infringement action against
Intel.

            10.2  Intel disclaims and shall have no obligation of defense,
contribution, or indemnity with respect to any actual or alleged intellectual
property infringement with respect to Intel intellectual property rights or
otherwise arising out of this Agreement. Intel shall have no liability arising
out of any such actual or alleged intellectual property infringement. Intel
shall have no obligation to intervene in any such infringement action against
Rambus.

      11.   Limitation of Liability.

            EXCEPT FOR BREACHES OF THE CONFIDENTIALITY PROVISIONS IN SECTION 20,
IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR ANY SPECIAL, CONSEQUENTIAL,
INDIRECT, OR INCIDENTAL DAMAGES, HOWEVER CAUSED, ON ANY THEORY OF LIABILITY AND
WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES,
ARISING OUT OF THIS AGREEMENT PROVIDED PURSUANT TO THIS AGREEMENT. IN NO EVENT
WILL RAMBUS' LIABILITY ARISING OUT OF THIS AGREEMENT EXCEED THE FEES RECEIVED BY
RAMBUS HEREUNDER. IN NO EVENT WILL INTEL'S LIABILITY ARISING OUT OF THIS
AGREEMENT EXCEED THE FEES PAID OR PAYABLE BY INTEL HEREUNDER, PROVIDED, HOWEVER,
THAT THIS MAXIMUM LIABILITY OF INTEL SHALL BE IN ADDITION TO INTEL'S OBLIGATION
TO PAY ALL FEES PAYABLE, BUT UNPAID, BY INTEL. THESE LIMITATIONS, HOWEVER, SHALL
NOT APPLY TO INFRINGEMENT OF THE OTHER PARTY'S INTELLECTUAL PROPERTY RIGHTS.

      12.   Payments to Rambus. In recognition of the mutual covenants and
benefits contained herein, and in return for the license granted above, Intel
shall pay to Rambus the amounts, and at the times, specified in Exhibit C.

      13.   Intel Reports. If in any calendar quarter twenty percent (20%) or
more, on a unit volume basis, of Intel's main memory controllers shipped by
Intel in the prior quarter were "Compatible" (as such term is defined in the
1996 Agreement as Amended), then Intel shall so notify Rambus in writing by the
forty-fifth (45th) day of the following calendar quarter. If Intel so

                                       - 11 -

<PAGE>

notifies Rambus for two (2) consecutive calendar quarters, then Intel's notice
obligation pursuant to this section shall thereupon terminate.

      14.   This Agreement is Non Assignable. This Agreement, or any right or
obligation hereunder, is not assignable without the prior written consent of the
other party, except as provided in this section and Sections 15 and 17. Any
attempted assignment or transfer other than as provided in Sections 15 and 17
shall be considered a material breach of this Agreement by the party attempting
such assignment for which the sole and exclusive remedy for the non-assigning
party shall be to terminate this Agreement. Rambus shall be entitled to engage
in a Change of Control, subject to Section 15.

      15.   Change of Control. In the event of a Change of Control of Rambus,
Intel shall be entitled, at its option, on written notice to Rambus within
thirty (30) days after the later of written notice to Intel of the Change of
Control, or the effective date of the Change of Control, to terminate this
Agreement. If Intel does not so terminate the Agreement, then as of the
effective date of the Change of Control, (i) for purposes of Section 1.15
(Patents) (and therefore Sections 1.10 (Intel Patents) and 1.21 (Rambus
Patents)), "during the term of this Agreement" shall be deemed to mean during
the term of this Agreement until the effective date of the Change of Control,
and (ii) the definitions of Memory Interfaces and Other Interfaces shall be
revised to mean only those Memory Interfaces and Other Interfaces that are
commercially available as of the effective date of such Change of Control or
that become available within one hundred eighty (180) days following such date.
For the avoidance of doubt, Rambus Patents shall be limited to those Rambus
Patents licensed to or licensable to Intel under this Agreement immediately
prior to the Change of Control and such Change of Control shall not under any
circumstances cause Intel to be licensed under any additional Patents of an
entity acquiring control of Rambus or acquired by Rambus in connection with the
Change of Control.

      16.   Limited Right to Suspend Patent License for Sales to Affiliates.

            16.1  For purposes of this Section 16, "Affiliate" means any entity,
other than a Subsidiary of Rambus, that is directly or indirectly controlled by,
under common control with or that controls Rambus. For purposes of this
definition control means direct or indirect ownership of or the right to
exercise (a) (i) at least fifty percent (50%) of the outstanding shares or
securities entitled to vote for the election of directors or similar managing
authority of the subject entity; or (ii) at least fifty percent (50%) of the
ownership interest representing the right to make the decisions for the subject
entity or (b) an interest sufficient to receive at least thirty percent (30%) of
the profits and/or losses of such entity.

            16.2  Notwithstanding anything herein to the contrary, Intel shall
have the limited right to suspend the licenses granted under this Agreement to
Rambus with respect to sales to or on behalf of an Affiliate of Rambus if:

                  (a)   the Affiliate is a direct or indirect customer of
Rambus; and

                                       - 12 -

<PAGE>

                  (b)   the Affiliate initiates a legal or administrative
proceeding against Intel and/or any of its Subsidiaries ("Affiliate's
Proceeding") alleging that Intel or any of its Subsidiaries infringes a patent
right of the Affiliate, and

                  (c)   the alleged infringing activity would have been licensed
to Intel had the identified patent right been owned or controlled by Rambus.

            16.3  If Intel elects to suspend the licenses granted under this
Agreement pursuant to this Section 16, Intel shall give written notice of such
suspension to Rambus. The suspension shall apply with respect to products
licensed under this Agreement pursuant to the licenses and sublicenses granted
to Rambus and only for such products that are sold to such Affiliate. Such
suspension shall be effective sixty (60) days following the date of such written
notice, and shall allow Intel to assert a claim of infringement against the
Affiliate that brought the original claim against Intel. Such suspension shall
terminate upon resolution (by settlement, judgment (other than a judgment in
Intel's favor), or otherwise) of the Affiliate's Proceeding.

            16.4  Intel agrees that it shall not seek monetary damages against
Rambus but rather shall look to the Affiliate for monetary damages. Intel shall
not assert a patent claim directly against Rambus until it has first exhausted
its legal remedies directly against the Affiliate. If Intel resolves its patent
dispute with the Affiliate, either through entrance of a judgment or by
settlement of the dispute, Intel agrees that it shall not bring a separate
action against Rambus with respect to products sold to such Affiliate.

      17.   Intel Assignment to Successor. Intel may transfer or assign this
Agreement to a person or entity into which it has merged or which has otherwise
succeeded to all or substantially all of its business or assets, and which has
assumed in writing or by operation of law its obligations under this Agreement.

      18.   Term and Termination.

            18.1  This Agreement shall begin on the Effective Date and, unless
earlier terminated, shall remain in force until September 30, 2006 (hereafter
the "Expiration Date"). Thereafter, unless this Agreement is terminated prior to
the Expiration Date, the licenses and rights described in Sections 3 and 4, and
Sections 5, 6, 7 and 8, shall continue for the life of all Rambus Patents and
Intel Patents in existence or having a first filing date prior to the Expiration
Date (or, as applicable, pursuant to the second sentence of Section 15, prior to
the effective date of a Change of Control of Rambus).

            18.2  Either party may terminate this Agreement prior to the
Expiration Date in the event of a material breach by the other party which is
not cured within 30 days following receipt of a written notice of such material
breach under the provisions contained in Section 25.5 below.

            18.3  Intel may, at its option, terminate this Agreement for
convenience upon sixty (60) days prior written notice to Rambus.

                                       - 13 -

<PAGE>

            18.4  In the event that Intel or any of its Subsidiaries initiates
any judicial (including arbitration, International Trade Commission, and similar
proceedings, but not including simple disputes over inventorship by Intel or its
Subsidiaries, or an employee or other individual obligated to assign the
applicable patent to Intel or its Subsidiaries, in the form of interferences in
the Patent and Trademark Office or an action under 35 U.S.C. Section 146 or 256
(or any foreign equivalent thereof)) or administrative action or proceeding to
challenge the validity and/or enforceability of any Rambus Patent, Rambus may,
at its option and as its sole and exclusive remedy therefor under this
Agreement, (i) terminate Intel and its Subsidiaries' license to such challenged
Patents, or (ii) in the case of the initiation by Intel of any judicial,
arbitration, International Trade Commission, or similar proceeding, terminate
this Agreement, in each case on written notice to Intel pursuant to Section
18.2, it being expressly agreed that neither Intel nor its Subsidiaries may
enjoy a license to such Patent(s) while at the same time seeking to invalidate
or render such Patent unenforceable. The parties agree, however, that no right
of termination under this section shall arise if the challenge is (a) in
response to or defense of an action initiated by Rambus, or (b) required by
virtue of a contractual obligation to indemnify a third party in a patent
infringement action initiated by Rambus.

            18.5  In the event of a termination prior to the Expiration Date,
all licenses, rights, benefits, and obligations shall cease as of the effective
date of termination, provided however, that (i) any payment amounts accrued
prior to the effective date of termination shall remain due and payable, and
(ii) the provisions of Sections 2, 8, 9, 10, 11, 13, 14, 17, 18.5, 18.6, 19 (to
the extent such licenses survive), 20, 21, 22, 23, 24 and 25 (except 25.3) shall
survive any expiration or termination of this Agreement for any reason.

            18.6  Upon (a) any failure by Intel to [*], and thereafter Intel
fails to [*], or (b) [*], then immediately [*]:

      (i)   Intel shall be [*] obligated to [*];

      (ii)  Intel shall [*];

      (iii) Intel agrees that this [*] obligation is unconditional and shall not
            be subject to any defenses, claims, or counterclaims, Intel may have
            (including without limitation any default by Rambus), which
            defenses, claims, and counterclaims Intel hereby irrevocably waives;
            and

      (iv)  Rambus shall be entitled to [*].

      19.   Remedies. The parties stipulate that in any action between the
parties for breach of this Agreement or infringement of the Patents licensed
herein, money damages in an amount to be determined at the trial or in an
alternative dispute resolution proceeding will be a complete and adequate remedy
and that in no event will either party seek equitable remedies of any sort.
Intel and Rambus agree that this Agreement may not be used, in any way, to
establish or prove a reasonable royalty under the Rambus Patents.

      20.   Confidentiality of Agreement. The parties hereto shall keep this
Agreement and the terms of this Agreement confidential and shall not now or
hereafter divulge these terms to any third party except:

            20.1  with the prior written consent of the other party; or

            20.2  to any governmental body having jurisdiction to call therefor;
or

            20.3  subject to Section 20.4 below, as otherwise may be required by
applicable securities and other law and regulation or by legal process,
including to legal and financial advisors in their capacity of advising a party
in such matters; or

            20.4  during the course of litigation so long as the disclosure of
such terms and conditions are restricted in the same manner as is the
confidential information of other litigating parties and so long as (a) the
restrictions are embodied in a court-entered protective order limiting
disclosure to counsel and (b) the disclosing party informs the other party in
writing at least ten (10) business days in advance of the disclosure;

            20.5  in confidence to legal counsel, accountants, banks and
financing sources and their advisors; or

            20.6  by Rambus, to other Rambus licensees to the extent necessary
(in Rambus' reasonable opinion) to satisfy contractual obligations to such other
Rambus Licensees but only after consulting with Intel regarding the identity of
such licensee and obtaining Intel's consent regarding the scope of the
disclosure to such Licensee.

      21.   Prior Licenses. The 1996 Agreement as Amended shall terminate as of
            the Effective Date, and the rights and licenses of each party under,
            or with respect to the patents or other intellectual property of the
            other party and its Subsidiaries, shall be governed by this
            Agreement. Any other agreement between the parties (including
            without limitation, the parties' SerDes Semiconductor Technology
            Agreement, executed May 24, 2001 ("SerDes Agreement")) shall not be
            affected by this Agreement. Notwithstanding the foregoing and
            notwithstanding Section 9.3 or any other provision of the 1996
            Agreement as Amended, (i) only the following sections of the 1996
            Agreement as Amended shall survive, and only as to acts or events
            occurring during the term of the 1996 Agreement as Amended: Sections
            1, 4.7, 4.8, 6, 7, 8, and 11 (except 11.1 (f)(i)-(f)(iv)); and (ii)
            Section 3.1(a) of the 1996 Agreement as Amended shall survive
            (provided that it is understood and agreed that, with respect to the
            definition of "Applicable Intel Intellectual Property Rights" in
            Section 1.27 of the 1996 Agreement as Amended, "the term of this
            Agreement" shall mean and be limited to the term of the 1996
            Agreement as Amended). In addition, the trade secret, copyright, and
            mask work right licenses granted in the 1996 Agreement as Amended
            shall continue in full force and effect (but only as to trade
            secrets, copyrights, and mask work rights licensed prior to the
            Effective Date of this Agreement), but shall not survive termination
            of this Agreement prior to the Expiration Date. For the avoidance of
            doubt, Sections 4.6 and 9 of the 1996 Agreement as Amended are void,
            and neither party shall have any rights arising out of Section 4.6
            or 9 of the 1996 Agreement as Amended.

      22.   Warrant Termination. The parties agree that all Intel warrants to
purchase Rambus stock, and associated rights, which were granted to Intel in
connection with the 1996 Agreement as Amended, are terminated. Within thirty
(30) days after the Effective Date of this Agreement, the parties shall enter
into such termination agreements as may be necessary to effect such
terminations.

      23.   [*]. Within [*] of the Effective Date of this Agreement, both
parties agree [*]. Both parties agree that [*]. The [*] is intended [*] as [*],
and shall not be construed as [*].

      24.   Merger: The terms and conditions herein contained constitute the
entire agreement between the parties and supersedes all previous agreements and
understandings, whether oral or written, between the parties hereto with respect
to the subject matter hereof, with the exception of the SerDes Agreement. All
prior, contemporaneous, and future discussions involving the subject matter set
forth in this Agreement are merged in this Agreement. This Agreement may not be
amended except in writing signed by a duly authorized representative of the
respective parties. Except as set forth in Section 21 above, any other
agreements between the parties, including nondisclosure agreements, shall not be
affected by this Agreement. No other rights are granted herein except as
expressly set forth in this Agreement.

      25.   Miscellaneous.

            25.1  Controlling Law. This Agreement and the interpretation of the

terms set forth herein shall be governed by and made in accordance with Delaware
law.

            25.2  Jurisdiction. Intel and Rambus agree that all disputes and

Delaware or of the federal courts sitting therein.

            25.3  Announcement. Upon execution of this Agreement by both
                  ------------
parties, Rambus shall have the right to issue a press release as attached as
Exhibit A, announcing this Agreement and stating that the Agreement has a term
of five (5) years and covers the licensing of Patents; and that the Agreement
includes a lump-sum quarterly payment. Any other disclosure to third parties
regarding this Agreement shall be governed by section 20.

            25.4  Dispute Resolution. All disputes arising directly under the
                  ------------------
express terms of this Agreement or the grounds for termination thereof shall be
resolved as follows: First, the senior management of both parties shall meet to
attempt to resolve such disputes. If the disputes cannot be resolved by the
senior management, either party may make a written demand for formal dispute
resolution. Within thirty (30) days after such written demand, the parties agree
to meet for one day with an impartial mediator and consider dispute resolution
alternatives other than litigation. If an alternative method of dispute
resolution is not agreed upon within thirty (30) days after the one day
mediation, either party may begin litigation proceedings.

                 RAMBUS AND INTEL SIGN NEW COMPREHENSIVE PATENT

                             CROSS LICENSE AGREEMENT

      Los Altos/Santa Clara, California. - Sept XX, 2001 -- Rambus Inc.
(Nasdaq:RMBS) and Intel Corporation today signed a comprehensive patent cross
license agreement that supercedes the prior agreement between the companies.

      The new cross license provides complete patent coverage to Intel for all
patents while providing Rambus license coverage necessary for Rambus high-speed
interface businesses. The agreement will have positive material impact on
Rambus' current financial which Rambus will discuss during its webcast on
Monday, September 17, 2001 at 6:00 a.m. Pacific Daylight Time. The specific
terms of the agreement are confidential.

      "We have had a long and mutually beneficial relationship with Intel. As an
R&D hub for high speed interfaces, Rambus' objective is to produce innovations
that will benefit the semiconductor and system industries, and by licensing
these innovations to generate a return on our investment to our shareholders."
said Geoff Tate, Rambus' chief executive officer. "We believe the RDRAM standard
is the best solution for the majority of the market and our top priority, but as
evidenced by this license with Intel, we are pleased to license our other
memory, communications, and backplane inventions as well."

      "This broad agreement will help Intel continue to be a leader in providing
high performance chipsets," said Craig Barrett, Intel president and chief
executive officer. "We also look forward to continued cooperation with Rambus in
the further development of RDRAM compatible chipsets and communications chips as
well their support of Infiniband and other future initiatives."
