     THIS REGISTRATION RIGHTS AGREEMENT (the "Agreement") is dated and deemed
effective as of February 22, 2000 by and among Nextel Partners, Inc. (the
"Company") and the shareholders listed on the signature pages hereto. Terms that
are not defined in context are used as defined in Section 24.

                               W I T N E S S E T H

     WHEREAS, the parties hereto were parties to that certain Shareholders'
Agreement dated January 29, 1999 which was amended and restated on February 18,
2000 and was further amended as of February 22, 2000 (collectively, the
"Shareholders' Agreement");

     WHEREAS, in connection with the initial public offering by the Company of
shares of its Class A Common Stock (the "Common Stock"), certain shareholders
who were parties to the Shareholders' Agreement agreed to be removed from the
Shareholders' Agreement and agreed to be parties to this Registration Rights
Agreement (hereinafter the shareholders who have been removed from the
Shareholders' Agreement and who are parties to this Registration Rights
Agreement shall be referred to herein individually as a "Shareholder Party" and
collectively as "Shareholder Parties");

     The parties hereto agree as follows:

     1.   PIGGYBACK REGISTRATION RIGHTS, COMPANY REGISTRATION.

     (a)  If the Company proposes to register any of its Company Common Stock
under the Securities Act (other than a registration (x) on Form S-8 or S-4 or
any successor or similar forms, (y) relating to securities issuable upon
exercise of employee stock options or in connection with any employee benefit or
similar plan of the Company or (z) in connection with a direct or indirect
merger, acquisition or other similar transaction), whether or not for sale for
its own account, it will each such time, subject to the provisions of Section
1(b), give prompt written notice to each Shareholder Party at least 20 days
prior to the anticipated filing date of the registration statement relating to
such registration, which notice shall set forth such Shareholder Party's rights
under this Section 1 and shall offer all Shareholder Parties the opportunity to
include in such registration statement such number of Registrable Securities as
each such Shareholder Party may request. Upon the written request of any such
Shareholder Party made within 10 days after the receipt of notice from the
Company (which request shall specify the number of Registrable Securities
intended to be disposed of by such Shareholder Party), the Company will use all
reasonable efforts to effect the registration under the Securities Act of all
Registrable Securities which the Company has been so requested to register by
such Shareholder Parties, to the extent requisite to permit the disposition of
the Registrable Securities so to be registered; PROVIDED that (i) if such
registration involves an

                                                                               1
<PAGE>

Underwritten Public Offering, all such Shareholder Parties requesting to be
included in the Company's registration must sell their Registrable Securities to
the underwriters on the same terms and conditions as apply to the Company or the
Demanding Shareholder, as applicable, and (ii) if, at any time after giving
written notice of its intention to register any Company Common Stock pursuant to
this Section 1(a) and prior to the effective date of the registration statement
filed in connection with such registration, the Company shall determine for any
reason not to register such Company Common Stock, the Company shall give written
notice to all Shareholder Parties and, thereupon, shall be relieved of its
obligation to register any Registrable Securities in connection with such
registration. The Company will pay all Registration Expenses in connection with
each registration of Registrable Securities requested pursuant to this Section
1.

     (b)  If a registration described in this Section 1 involves an Underwritten
Public Offering (other than in the case of an Underwritten Public Offering
requested by any Demanding Shareholder in a Demand Registration in which case
the provisions with respect to priority of inclusion in such offering set forth
in Section 2(b) below shall apply) and the managing underwriter advises the
Company in writing that, in its view, the number of shares of Company Common
Stock which the Company and any Shareholder Parties intend to include in such
registration exceeds the Maximum Offering Size, the Company will include in such
registration, in the following priority, up to the Maximum Offering Size:

          (i)  first, so much of the Company Common Stock proposed to be
               registered for the account of the Company as would not cause the
               offering to exceed the Maximum Offering Size; and

          (ii) second, all Registrable Securities requested to be included in
               such registration by a Shareholder Party and by a party to the
               Shareholders' Agreement, (allocated, if necessary for the
               offering not to exceed the Maximum Offering Size, pro rata among
               such Shareholder Parties and the parties to the Shareholders'
               Agreement on the basis of the relative number of shares of
               Registrable Securities so requested to be included in such
               registration).

     2.   PIGGYBACK REGISTRATION RIGHTS, DEMAND REGISTRATION

     (a)  Should a Demanding Shareholder make a Demand Registration of the
Company, then the Company shall promptly give written notice of the Demand
Registration at least 30 days prior to the anticipated filing date of the
registration statement relating to such Demand Registration to the Shareholder
Parties and thereupon will use its reasonable best efforts to effect, as
expeditiously as possible, the registration under the Securities Act of:

          (i)  The Registrable Securities which the Company has been so
               requested to register by the Demanding Shareholder, then held by
               the Demanding Shareholder; and

                                                                               2
<PAGE>

          (ii) Subject to the restrictions set forth in Section 1 (a) above, all
               other Registrable Securities which any Shareholder Party and any
               party to the Shareholders' Agreement has requested the Company to
               register by written request received by the Company within 15
               days after the receipt by such Shareholder Party and party to the
               Shareholders' Agreement of such written notice given by the
               Company,

all to the extent necessary to permit the disposition (in accordance with the
intended methods thereof as aforesaid) of the Registrable Securities so to be
registered.

     (b)  If a Demand Registration involves an Underwritten Public Offering and
the managing underwriter advises the Company that, in its view, (x) the number
of shares of Company Common Stock requested to be included in such registration
(including Company Common Stock which the Company proposes to be included which
are not Registrable Securities) or (y) the inclusion of some or all of the
shares of Company Common Stock owned by the Demanding Shareholders or the
Shareholder Parties, in any such case, exceeds the Maximum Offering Size, the
Company will include in such registration in the priority listed below, up to
the Maximum Offering Size:

          (i)  first, all Registrable Securities requested to be registered by
               the Demanding Shareholders (including any Registered Securities
               requested to be registered by the High Yield Investors)
               (allocated, if necessary for the offering not to exceed the
               Maximum Offering Size pro rata among the Demanding Shareholders
               and the High Yield Investors on the basis of the relative number
               of Registrable Securities so requested to be included in such
               registration);

          (ii) second, all Registrable Securities requested to be included in
               such registration by Shareholder Parties and parties to the
               Shareholders' Agreement other than the Demanding Shareholders and
               the High Yield Investors (allocated, if necessary for the
               offering not to exceed the Maximum Offering Size, pro rata among
               such Shareholder Parties and such parties to the Shareholders'
               Agreement on the basis of the relative number of Registrable
               Securities so requested to be included in such registration); and

         (iii) third, any Company Common Stock proposed to be registered by the
               Company.

     3.   HOLDBACK AGREEMENTS. With respect to each and every Underwritten
Public Offering:

     (a) each Shareholder Party agrees not to effect any public sale or
distribution, including any sale pursuant to Rule 144, or any successor
provision, under the Securities Act, of any Registrable Securities, and not
to effect any such public sale or distribution of any other security of the
Company (in each case, other than as part of such Underwritten Public
Offering) during the 14 days prior to the effective date of the applicable
registration statement (except as part of such registration) or during the
period after such effective date that such managing underwriter and the
Company shall agree (but not to exceed 180 days or any such shorter period
(but not less than 90 days) as the managing underwriter may suggest).

                                                                               3
<PAGE>

     (b)  Each Shareholder Party agrees that, so long as a Demanding Shareholder
has the right to request one or more Demand Registrations, each Shareholder
Party will not effect any public sale or distribution, including any sale
pursuant to Rule 144, or any successor provision, under the Securities Act, of
any Registrable Securities, or any such public sale or distribution of any other
security of the Company, from the date that the Shareholder Party is first
notified of the Company's intention to make a Public Offering through the date
that is 90 days following completion of such Public Offering, unless the
underwriting group, not including Donaldson, Lufkin and Jenrette, Inc. or any of
its controlled affiliates, permits such sales or distributions to be made by a
Shareholder Party during such 90 day period.

     4.   REGISTRATION PROCEDURES. Whenever Shareholder Parties request that any
Registrable Securities be registered pursuant to Section 1 or 2 hereof, the
Company will, subject to the provisions of such Sections, use all reasonable
efforts to effect the registration and the sale of such Registrable Securities
in accordance with the intended method of disposition thereof as quickly as
practicable, and in connection with any such request:

     (a)  The Company will as expeditiously as possible prepare and file with
the SEC a registration statement on any form selected by counsel for the Company
and which form shall be available for the sale of the Registrable Securities to
be registered thereunder in accordance with the intended method of distribution
thereof, and use all reasonable efforts to cause such filed registration
statement to become and remain effective for a period of not less than 90 days
(or such shorter period in which all of the Registrable Securities of the
Shareholder Parties included in such registration statement shall have actually
been sold thereunder).

     (b)  The Company will, if requested, prior to filing a registration
statement or prospectus or any amendment or supplement thereto, furnish to each
Shareholder Party and each underwriter, if any, of the Registrable Securities
covered by such registration statement copies of such registration statement as
proposed to be filed, and thereafter the Company will furnish to such
Shareholder Party and underwriter, if any, such number of copies of such
registration statement, each amendment and supplement thereto (in each case
including all exhibits thereto and documents incorporated by reference therein),
the prospectus included in such registration statement (including each
preliminary prospectus) and such other documents as such Shareholder Party or
underwriter may reasonably request in order to facilitate the disposition of the
Registrable Securities owned by such party. Each Shareholder Party shall have
the right to request that the Company modify any information contained in such
registration statement, amendment and supplement thereto pertaining to such
party and the Company shall use all reasonable efforts to comply with such
request, PROVIDED, HOWEVER, that the Company shall not have any obligation to so
modify any information if so doing would cause the prospectus to contain an
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein (in light of
the circumstances under which they were made) not misleading.

                                                                               4
<PAGE>

     (c)  After the filing of the registration statement, the Company will
promptly notify each Shareholder Party holding Registrable Securities covered by
such registration statement of any stop order issued or threatened by the SEC or
any state securities commission under state blue sky laws and take all
reasonable actions required to prevent the entry of such stop order or to remove
it if entered.

     (d)  The Company will use all reasonable efforts to (i) register or qualify
the Registrable Securities covered by such registration statement under such
other securities or blue sky laws of such jurisdictions in the United States as
any Shareholder Party holding such Registrable Securities reasonably (in light
of such party's intended plan of distribution) requests and (ii) cause such
Registrable Securities to be registered with or approved by such other
governmental agencies or authorities as may be necessary by virtue of the
business and operations of the Company and do any and all other acts and things
that may be reasonably necessary or advisable to enable such Shareholder Party
to consummate the disposition of the Registrable Securities owned by such party;
PROVIDED that the Company will not be required to (A) qualify generally to do
business in any jurisdiction where it would not otherwise be required to qualify
but for this paragraph (d), (B) subject itself to taxation in any such
jurisdiction or (C) consent to general service of process in any such
jurisdiction.

     (e)  The Company will immediately notify each Shareholder Party holding
such Registrable Securities covered by such registration statement, at any time
when a prospectus relating thereto is required to be delivered under the
Securities Act, of the occurrence of an event requiring the preparation of a
supplement or amendment to such prospectus so that, as thereafter delivered to
the purchasers of such Registrable Securities, such prospectus will not contain
an untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein (in
light of the circumstances under which they were made) not misleading and
promptly prepare and make available to each such Shareholder Party and file with
the SEC any such supplement or amendment.

     (f)  The Company will enter into customary agreements (including an
underwriting agreement in customary form) and take such other actions as are
reasonably required in order to expedite or facilitate the disposition of such
Registrable Securities, including the engagement of a "qualified independent
underwriter" in connection with the qualification of the underwriting
arrangements with the NASD.

     (g)  Upon execution of confidentiality agreements in form and substance
reasonably satisfactory to the Company, the Company will make available for
inspection by any party and any underwriter participating in any offering
pursuant to a registration statement being filed by the Company pursuant to this
Section 4 and any attorney, accountant or other professional retained by any
Shareholder Party or underwriter (collectively, the "INSPECTORS"), all financial
and other records, pertinent corporate documents and properties of the Company
(collectively, the "RECORDS") as shall be reasonably requested by any such
Person, and cause the Company's officers, directors and employees to supply all
information reasonably requested by any Inspectors in connection with such
registration statement.

                                                                               5
<PAGE>

     (h)  The Company will furnish to each Shareholder Party and to each such
underwriter, if any, a signed counterpart, addressed to such underwriter and the
participating Shareholder Party , of (i) an opinion or opinions of counsel to
the Company and (ii) a comfort letter or comfort letters from the Company's
independent public accountants, each in customary form and covering such matters
of the type customarily covered by opinions or comfort letters, as the case may
be, as a majority in interest of such Shareholder Party or the managing
underwriter therefor reasonably requests.

     (i)  The Company will otherwise use all reasonable efforts to comply with
all applicable rules and regulations of the SEC, and make available to its
security holders, as soon as reasonably practicable, an earnings statement
covering a period of 12 months, beginning within three months after the
effective date of the registration statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act.

     (j)  The Company may require each Shareholder Party (i) to promptly furnish
in writing to the Company information regarding the distribution of the
Registrable Securities as the Company may from time to time reasonably request,
(ii) to provide such other information as may be legally required in connection
with such registration and (iii) to take such other acts as are reasonably
necessary under the circumstances.

     (k)  Each Shareholder Party agrees that, upon receipt of any notice from
the Company of the happening of any event of the kind described in Section 4(e),
such Shareholder Party will forthwith discontinue disposition of Registrable
Securities pursuant to the registration statement covering such Registrable
Securities until such Shareholder Party's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 4(e), and, if so
directed by the Company, such Shareholder Party will deliver to the Company all
copies, other than any permanent file copies then in such Shareholder Party's
possession, of the most recent prospectus covering such Registrable Securities
at the time of receipt of such notice. In the event that the Company shall give
such notice, the Company shall extend the period during which such registration
statement shall be maintained effective (including the period referred to in
Section 4(a)), by the number of days during the period from and including the
date of the giving of notice pursuant to Section 4(e) to the date when the
Company shall make available to such Shareholder Party a prospectus supplemented
or amended to conform with the requirements of Section 4(e).

     5.   INDEMNIFICATION BY THE COMPANY. The Company agrees to indemnify and
hold harmless each Shareholder Party hereto holding Registrable Securities
covered by a registration statement, its officers, directors, employees,
partners and agents, and each Person, if any, who controls such Shareholder
Party within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act from and against any and all losses, claims, damages,
liabilities and expenses caused by (i) any untrue statement or alleged untrue
statement of a material fact contained in any registration statement,
prospectus, offering circular or other offering document relating to the
Registrable Securities (as amended or supplemented if the Company shall have
furnished any amendments or supplements thereto) or any preliminary prospectus,
or (ii) any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make

                                                                               6
<PAGE>

the statements therein not misleading (in the case of any prospectus, in light
of the circumstances under which they were made), except insofar as such losses,
claims, damages or liabilities are caused by any such untrue statement or
omission or alleged untrue statement or omission so made in strict conformity
with information furnished in writing to the Company by such Shareholder Party
or on such Shareholder Party's behalf expressly for use therein or (iii) any
violation by the Company of the Securities Act or any rule or regulation
promulgated thereunder applicable to the Company, or any blue sky or state
securities laws or any rule or regulation thereunder applicable to the Company;
PROVIDED that with respect to any untrue statement or omission or alleged untrue
statement or omission made in any preliminary prospectus, or in any prospectus,
as the case may be, the indemnity agreement contained in this paragraph shall
not apply to the extent that any such loss, claim, damage, liability or expense
results from the fact that a current copy of the prospectus (or, in the case of
a prospectus, the prospectus as amended or supplemented) was not sent or given
to the Person asserting any such loss, claim, damage, liability or expense at or
prior to the written confirmation of the sale of the Registrable Securities
concerned to such Person if it is determined that the Company has provided such
prospectus to such Shareholder Party in a timely manner prior to such sale and
it was the responsibility of such Shareholder Party under the Securities Act to
provide such Person with a current copy of the prospectus (or such amended or
supplemented prospectus, as the case may be) and such current copy of the
prospectus (or such amended or supplemented prospectus, as the case may be)
would have cured the defect giving rise to such loss, claim, damage, liability
or expense. The Company also agrees to indemnify any underwriters of the
Registrable Securities and each accountant, attorney and other Person who
participates in the offering of the Registrable Securities on behalf of the
Company or any selling shareholder, their officers and directors and each person
who controls such underwriters and other Persons on substantially the same basis
as that of the indemnification of the parties provided in this Section 5.

     6.   INDEMNIFICATION BY PARTICIPATING PARTIES. Each Shareholder Party
holding Registrable Securities included in any registration statement agrees,
severally but not jointly, to indemnify and hold harmless the Company, its
officers, directors and agents and each Person, if any, who controls the Company
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act to the same extent as the foregoing indemnity from the Company
to such Shareholder Party, but only (i) with respect to information furnished in
writing by such Shareholder Party or on such party's behalf expressly for use in
any registration statement, prospectus, offering circular or other document
relating to the Registrable Securities, or any amendment or supplement thereto,
or any preliminary prospectus or (ii) to the extent that any loss, claim,
damage, liability or expense described in Section 5 results from the fact that a
current copy of the prospectus (or, in the case of a prospectus, the prospectus
as amended or supplemented) was not sent or given to the Person asserting any
such loss, claim, damage, liability or expense at or prior to the written
confirmation of the sale of the Registrable Securities concerned to such Person
if it is determined that it was the responsibility of such Shareholder Party to
provide such Person with a current copy of the prospectus (or such amended or
supplemented prospectus, as the case may be) and such current copy of the
prospectus (or such amended or supplemented prospectus, as the case may be)
would

                                                                               7
<PAGE>

have cured the defect giving rise to such loss, claim, damage, liability or
expense. Each Shareholder Party shall be prepared, if required by the
underwriting agreement, to indemnify and hold harmless any underwriters of the
Registrable Securities and each accountant, attorney and other Person who
participates in the offering of the Registrable Securities on behalf of the
Company or any selling parties, their officers and directors and each person who
controls such underwriters and other Persons on substantially the same basis as
that of the indemnification of the Company provided in Section 5. As a condition
to including Registrable Securities in any registration statement filed in
accordance with this Agreement, the Company may require that it shall have
received an undertaking reasonably satisfactory to it from any underwriter to
indemnify and hold it harmless to the extent customarily provided by
underwriters with respect to similar securities.

     7.   CONDUCT OF INDEMNIFICATION PROCEEDINGS. In case any proceeding
(including any governmental investigation) shall be instituted involving any
Person in respect of which indemnity may be sought pursuant to this Agreement,
such Person (an "INDEMNIFIED PARTY"), after the Indemnified Party has actual
notice of any proceeding as to which indemnity may be sought, shall promptly
notify the Person against whom such indemnity may be sought (the "INDEMNIFYING
PARTY") in writing and the Indemnifying Party shall assume the defense thereof,
including the employment of counsel reasonably satisfactory to such Indemnified
Party, and shall assume the payment of all fees and expenses; PROVIDED that the
failure of any Indemnified Party so to notify the Indemnifying Party shall not
relieve the Indemnifying Party of its obligations hereunder except to the extent
that the Indemnifying Party is materially prejudiced by such failure to notify.
In any such proceeding, any Indemnified Party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such Indemnified Party unless (i) the Indemnifying Party and the Indemnified
Party shall have mutually agreed to the retention of such counsel or (ii) in the
reasonable judgment of such Indemnified Party representation of both parties by
the same counsel would be inappropriate due to actual or potential differing
interests between them. It is understood that the Indemnifying Party shall not,
in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel) at any time for
all such Indemnified Parties, and that all such fees and expenses shall be
reimbursed as they are incurred. In the case of any such separate firm for the
Indemnified Parties, such firm shall be designated in writing by the Indemnified
Parties. The Indemnifying Party shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such
consent, or if there be a final judgment for the plaintiff, the Indemnifying
Party shall indemnify and hold harmless such Indemnified Parties from and
against any and all losses, claims, damages, liabilities and expenses or
liability (to the extent stated above) by reason of such settlement or

                                                                               8
<PAGE>

judgment. No Indemnifying Party shall, without the prior written consent of the
Indemnified Party, effect any settlement of any pending or threatened proceeding
in respect of which any Indemnified Party is or could have been a party and
indemnity could have been sought hereunder by such Indemnified Party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability arising out of such proceeding.

     8.   CONTRIBUTION.

     (a)  If the indemnification provided for in this Agreement is held by a
court of competent jurisdiction to be unavailable to the Indemnified Parties in
respect of any losses, claims, damages, liabilities or expenses referred to
herein, then each such Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, damages, liabilities or
expenses (i) as between the Company and the Shareholder Parties holding
Registrable Securities covered by a registration statement and their related
Indemnified Parties on the one hand and the underwriters, other participating
Persons and their related Indemnified Parties on the other, in such proportion
as is appropriate to reflect the relative benefits received by the Company and
such Shareholder Parties on the one hand and the underwriters and other
participating Persons on the other, from the offering of the parties'
Registrable Securities, or if such allocation is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits but also the relative fault of the Company and the Shareholder Parties
on the one hand and of such underwriters and other participating Persons on the
other in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations and (ii) as between the Company and their related
Indemnified Parties on the one hand and each Shareholder Party and their related
Indemnified Parties on the other, in such proportion as is appropriate to
reflect the relative fault of the Company and of each such Shareholder Party in
connection with such statements or omissions, as well as any other relevant
equitable considerations. The relative benefits received by the Company and the
Shareholder Parties on the one hand and such underwriters and other
participating Persons on the other shall be deemed to be in the same proportion
as the total proceeds from the offering (net of underwriting discounts and
commissions but before deducting expenses) received by the Company and such
Shareholder Parties bear to the total underwriting discounts and commissions
received by such underwriters and fees received by other participating Persons,
in each case as set forth in the table on the cover page of the prospectus. The
relative fault of the Company and the Shareholder Parties on the one hand and of
such underwriters and other participating Persons on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company and the
Shareholder Parties or by such underwriters and other participating Persons. The
relative fault of the Company on the one hand and of each Shareholder Party on
the other shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by

                                                                               9
<PAGE>

a Shareholder Party and the Shareholder Party's relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

     (b)  The Company and the Shareholder Parties agree that it would not be
just and equitable if contribution pursuant to this Section 8 were determined by
pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an Indemnified Party as a result of the
losses, claims, damages, liabilities or expenses referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such Indemnified
Party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 8, no underwriter shall be
required to contribute any amount in excess of the underwriting discount
applicable to Securities purchased by such underwriter in such offering, less
the aggregate amount of any damages which such underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission, and no party shall be required to contribute any amount in
excess of the amount by which the total price at which the Registrable
Securities of such party hereto were offered to the public exceeds the amount of
any damages which such party has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. Each party's obligation
to contribute pursuant to this Section 8 is several in the proportion that the
proceeds of the offering received by such party bears to the total proceeds of
the offering received by all such parties hereto and not joint.

     9.   PARTICIPATION IN PUBLIC OFFERING. No Person may participate in any
Underwritten Public Offering hereunder unless such Person (a) agrees to sell
such Person's securities on the basis provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangements and (b)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements and the provisions of this Agreement.

     10.  COOPERATION BY THE COMPANY. In the event any Shareholder Party shall
transfer any Registrable Securities pursuant to Rule 144A under the Securities
Act, the Company shall cooperate, to the extent commercially reasonable, with
such Shareholder Party and shall provide to such Shareholder Party such
information as such Shareholder Party shall reasonably request, PROVIDED such
Shareholder Party shall pay any material expenses incurred by the Company in
connection with its cooperation.

     11.  NO TRANSFER OF REGISTRATION RIGHTS. None of the rights of parties
under this Agreement shall be assignable by any party to any Person acquiring
Securities in any Public Offering or pursuant to Rule 144A of the Securities
Act.

                                                                              10

     12.  LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. The Company shall not
enter into any agreement with any holder or prospective holder of any securities
of the Company that would allow such holder or prospective holder to include
such securities in any registration, (a) unless under the terms of such
agreement, such holder or prospective holder may include such securities in any
such registration only to the extent that the inclusion of such securities would
not reduce the amount of the Registrable Securities of the Shareholder Parties
included therein or (b) on terms otherwise more favorable to such holder or
prospective holder than provided in this Agreement. The Company shall not,
without the consent of the Shareholder Parties whose consent would be necessary
to amend this Agreement, consent to any amendment to the Shareholders' Agreement

shall terminate as to all parties on January 29, 2014 and shall terminate with
respect to any single Shareholder Party when such Shareholder Party no longer
owns any Registrable Securities. Notwithstanding the foregoing, the
indemnification and contribution provisions set forth in sections 5, 6, 7 and 8
shall survive termination of this Agreement.

     14.  ASSIGNABILITY. Neither this Agreement nor any right, remedy,
obligation or liability arising hereunder or by reason hereof shall be
assignable by any party.

     15.  WAIVER/AMENDMENTS. No provision of this Agreement may be waived except
by an instrument in writing executed by the party against whom the waiver is to
be effective. No provision of this Agreement may be amended or otherwise
modified except by an instrument in writing executed by the Company with
approval of its Board of Directors and holders of at least 75% of the shares of
Common Stock of the Company held by the Shareholder Parties to this Agreement at
the time of such proposed amendment or modification.

     16.  NOTICES. All notices and other communications given or made pursuant
hereto, unless otherwise specified, shall be in writing and shall be deemed to
have been duly given and received when sent by fax (with confirmation of
receipt) or delivered personally or on the third Business Day after being sent

Agreement, without posting any bond, and in addition to all other remedies which
may be available, shall be entitled to obtain equitable relief in the form of
specific performance, a temporary restraining order, a temporary or permanent
injunction or any other equitable remedy which may then be available.

the party that does not prevail.

     23.  SEVERABILITY. If one or more provisions of this Agreement are held to
be unenforceable to any extent under applicable law, such provision shall be
interpreted as if it were written so as to be enforceable to the maximum

in the attached EXHIBIT B. The Parties currently plan that the High Density
1T-SRAM Memories will include stand alone memory integrated circuits, which are
expected to use the MoSys 1T-SRAM technology.

       1.5    "MANUFACTURER'S AGREEMENT" means a confidential written agreement
that expressly refers to this Agreement by the names of the Parties and the
Effective Date and title set forth above, that is executed by MoSys and the
applicable third party integrated circuit manufacturer, and that expressly
covers integrated circuit products that use MoSys's 1T-SRAM technology that may
be sold to Nintendo for use in the Dolphin Product.

       1.6    "MOSYS INTELLECTUAL PROPERTY" means any and all know-how,
technical information, trade secrets, patents and patent applications owned or
controlled by MoSys (a partial list of which is attached in EXHIBIT C), which
(i) MoSys has the right to license, relating to memory architecture, protocol
and circuit implementation, and which (ii) are incorporated in the High Density
1T-SRAM Memory by MoSys. The term "MoSys Intellectual Property" does not include
any and all know-how, technical information, trade secrets and circuit
implementation which is (a) in the public domain, (b) known generally by persons
skilled in the art, (d) already in the rightful possession of Nintendo, (d)
hereafter becomes available for use without license, (e) owned or controlled by
others, including but not limited to which relating to generic DRAM processes,
memory cells, capacitor fabrication and memory operations, (f) hereafter becomes
rightfully known to Nintendo without restriction or (g) subsequently developed
independently by employees of Nintendo without access to the High Density
1T-SRAM Memory.

       1.7    "PER UNIT ROYALTY" means the per unit royalty payable by an
Authorized Manufacturer to MoSys under a Manufacturer's Agreement for the sale

additional units be manufactured as mutually agreed by the parties.

       1.10   "PURCHASE PRICE" means the gross sales amount invoiced or
otherwise charged to Nintendo by an Authorized Manufacturer for the purchase or
other disposition of a High Density 1T-SRAM Memory in finished and packaged form
in a fully arms length transaction, excluding import, export, value added,
excise and sales taxes, customs duties, and tariffs actually paid. In the event
that a High Density 1T-SRAM Memory is bundled with other products or otherwise
sold or disposed of under circumstances which might indicate that the
transaction was on other than a fully arms length basis, the Purchase Price
shall, upon MoSys's request, mean the fair market value of the High Density
1T-SRAM Memory. Such fair market value shall be determined by looking at the
arms length sales to third parties of similar MoSys products, or if such arms
length sales do not appear to provide a reasonable basis for the fair market
value, the arms length sales to third parties of similar MoSys and other
products.

       1.11   "QUARTER" means a period of three (3) consecutive calendar months

below.

SECTION 2.    LICENSE; PRODUCT PURCHASES

       2.1    AVAILABILITY OF PRODUCTS. MoSys is currently in discussions with
potential Authorized Manufacturers concerning the possible development,
manufacture, and sale of High Density 1T-SRAM Memories, but definitive
agreements have not yet been reached and High Density 1T-SRAM Memories have not
yet been developed. It is understood and agreed that Nintendo's ability to
obtain High Density 1T-SRAM Memories is contingent upon availability from
MoSys's Authorized Manufacturers and because availability is anticipated as
being only through such third parties, the design, performance, and availability
of High Density 1T-SRAM Memories may not be in MoSys's sole control. In light of
the foregoing, but subject to the last sentence in this Section 2.1, this
Agreement is not intended to obligate MoSys to sell, make available, or continue
to make available to Nintendo, or obligate Nintendo to purchase, any High
Density 1T-SRAM Memories. Rather, this Agreement is intended to establish the
Fees to be paid to MoSys by Nintendo for High Density 1T-SRAM Memories used in
the Dolphin Product only to the extent the High Density 1T-SRAM Memories become
and remain available through such Authorized Manufacturers. EXHIBIT A hereto may
be amended to add High Density 1T-SRAM Memories only by mutual written agreement
of both Parties and shall list the Authorized Manufacturers that are authorized
by MoSys to supply each High Density 1T-SRAM Memory. It is acknowledged that
this Agreement does not prevent the High Density 1T-SRAM Memories from being
modified, changed, or discontinued at any time, provided, however, that MoSys
shall deliver to Nintendo prior written

                                       3
<PAGE>

notice of any such modification, change or intent to discontinue.
Notwithstanding the foregoing, in the event definitive agreements are executed
and High Density 1T-SRAM Memories are developed, all applicable terms and
conditions of this Agreement shall apply to and govern the relationship between
Nintendo and MoSys.

       2.2    LICENSE; PURCHASE OF PRODUCTS. Subject to the terms and conditions
of this Agreement and acceptance of the High Density 1T-SRAM Memory from MoSys,
MoSys grants Nintendo as a preferred customer a royalty-bearing, world-wide
license to have manufactured by an Authorized Manufacturer, use, sell, and
distribute the High Density 1T-SRAM Memory acquired from and manufactured by any
Authorized Manufacturer. Nintendo shall also have the right to inform any
Authorized Manufacturer of the terms of this Agreement governing the waiver of
payment of Per Unit Royalties by any Authorized Manufacturer and the payment of
Fees by Nintendo in arranging such purchases. MoSys will confirm to the
Authorized Manufacturers these terms and will waive the obligation of Authorized
Manufacturers to pay Per Unit Royalties to MoSys under Manufacturers' Agreements
solely as follows. MoSys will waive each Authorized Manufacturer's obligation to
pay Per Unit Royalties to MoSys under a Manufacturer's Agreement for each
authorized sale by the Authorized Manufacturer to Nintendo of a High Density
1T-SRAM Memory that is used by Nintendo in the Dolphin Product; provided that
MoSys has received from Nintendo payment of the applicable Fees in accordance
with Section 3 below. Nintendo shall not request the waiver for, and the waiver
shall not apply to, any High Density 1T-SRAM Memories that are not incorporated
into the Dolphin Product. The waiver will be made in accordance with the terms
of the applicable Manufacturer's Agreement.

       2.3    DEVELOPMENT OF PROTOTYPE 1T-SRAM MEMORIES. MoSys deems Nintendo a
preferred customer and therefore agrees to develop on behalf of Nintendo the
Prototype 1T-SRAM Memories according to the specifications in the attached
EXHIBIT B. Upon timely completion of the Prototype 1T-SRAM Memories, MoSys shall
use commercially reasonable efforts to promptly deliver the Prototype 1T-SRAM
Memories to Nintendo along with associated design specifications and application
documents and further grants Nintendo the right to have the Prototype 1T-SRAM
Memories manufactured by an Authorized Manufacturer of Nintendo's choice in
accordance with the terms of the applicable Manufacturer's Agreement.

       2.4    NO OTHER RIGHTS. Except as expressly granted herein, nothing in
this Agreement grants to Nintendo any right or license to manufacture or to have
manufactured the High Density 1T-SRAM Memories or any right or license under any
intellectual property or proprietary rights of MoSys, whether by reliance,
implication, estoppel or otherwise. Nintendo shall not exercise its rights under
this Agreement in any manner, or take any other action, which adversely affects
MoSys's rights in and to the High Density 1T-SRAM Memories. ALL RIGHTS NOT
EXPRESSLY GRANTED HEREIN ARE RESERVED TO MOSYS. It is understood and agreed that
MoSys may in its sole discretion determine the terms and conditions to which it
wishes to agree in each Manufacturer's Agreement and that MoSys shall have no
obligations or responsibility to Nintendo to obtain any particular terms or
conditions, except that any manufacture or production of High Density 1T-SRAM
Memories shall meet the specifications set forth in the attached EXHIBIT B. It
is also understood and agreed that the actual price between Nintendo and the
Authorized Manufacturer for the purchase of High Density 1T-SRAM Memories is not
under MoSys's control and that MoSys shall have no obligations, responsibility
or liability concerning such price. Except as expressly granted herein, nothing
in this Agreement grants to MoSys any right or license under any intellectual

                                       4
<PAGE>

property or proprietary rights of Nintendo, whether by reliance, implication,
estoppel or otherwise. MoSys shall not exercise its rights under this Agreement
in any manner, or take any other action, which adversely affects Nintendo's
rights in and to the Dolphin Product. ALL RIGHTS NOT EXPRESSLY GRANTED HEREIN
ARE RESERVED TO NINTENDO.

       2.5    EXCLUSIVITY. MoSys agrees that, from the Effective Date through
December 31, 2001, providing Nintendo continues to actively promote the use
of 1T-SRAM as specified in this Agreement, MoSys agrees not to sell, provide
or otherwise distribute the same High Density 1T-SRAM Memory as specified in
EXHIBITS A and B to Sony Computer Entertainment Company or Sega Corporation
as part of their video game consoles. Notwithstanding the above, however,
MoSys shall have no obligation to impose such a restriction on any of its
licensees.

SECTION 3     COMPENSATION TO MOSYS

       3.1    PRODUCT FEES. In consideration of the preferred rights provided to
Nintendo hereunder, Nintendo shall pay to MoSys the negotiated Fee in the amount
set forth below for each High Density 1T-SRAM Memory for which Nintendo would
like MoSys to waive the Authorized Manufacturer's Per Unit Royalty in accordance
with Section 2.2 above:

       (a)    [*] of the Purchase Price for each of the first [*] units of
High Density 1T-SRAM Memory obtained from an Authorized Manufacturer; and

       (b)    [*] of the Purchase Price for each High Density 1T-SRAM Memory
obtained from an Authorized Manufacturer in excess of such first [*] units.

In the event any High Density 1T-SRAM Memories as delivered are not accepted by
Nintendo or are otherwise rejected due to defects or other performance problems
and such High Density 1T-SRAM Memories are returned to any Authorized
Manufacturer, Nintendo shall be entitled and have the right to deduct from and
set off against any amounts payable by Nintendo under this Agreement any amounts
owed by Nintendo to MoSys for such High Density 1T-SRAM Memories as described in
this Section 3.

       3.2    PROTOTYPE DEVELOPMENT FEES. In consideration of the development
and delivery to Nintendo of the Prototype 1T-SRAM Memories, Nintendo shall pay
to MoSys the negotiated Fee of [*] as set forth in EXHIBIT B.

Development Fees) shall be due and paid no later than [*] after the end of the
Quarter during which any High Density 1T-SRAM Memories were obtained from an
Authorized Manufacturer. All payments shall be calculated and made in United
States Dollars by wire transfer to:

                  Fax: +1 (408) 731-1893

unless otherwise specified in writing by MoSys. All notifications to MoSys shall
be accompanied by a written report from Nintendo showing the number of and
actual Purchase Price for each High Density 1T-SRAM Memory to which the payment
applies as well as the total number of each High Density 1T-SRAM Memory obtained
from each Authorized Manufacturer as of the date of the report.

       3.4    TAXES. Any and all Fees payable hereunder do not include any
government taxes (including without limitation sales, use, excise, and value
added taxes) or duties imposed by any governmental agency that are applicable to
the export, import, or purchase of the Products (other than taxes on the net
income of MoSys), and Nintendo shall bear all such taxes and duties. When MoSys
has a current or subsequent legal obligation to collect and/or pay such taxes,
the appropriate amount shall be added to Nintendo's invoice and paid by
Nintendo, unless Nintendo provides MoSys with a valid tax exemption certificate
authorized by the appropriate taxing authority. All payments by Nintendo
specified hereunder are expressed as net amounts and shall be made free and
clear of, and without reduction for, any withholding taxes. Any such taxes which
are otherwise imposed on payments to MoSys shall be the sole responsibility of
Nintendo. If any applicable law requires Nintendo to withhold amounts from any
payments to MoSys hereunder, (i) Nintendo shall effect such withholding, remit
such amounts to the appropriate taxing authorities and promptly furnish MoSys
with tax receipts evidencing the payments of such amounts, and (ii) the sum
payable by Nintendo upon which the deduction or withholding is based shall be
increased to the extent necessary to ensure that, after such deduction or
withholding, MoSys receives and retains, free from liability for such deduction
or withholding, a net amount equal to the amount MoSys would have received and
retained in the absence of such required deduction or withholding. In the event
that MoSys receives a reduction in tax due or rebate from any tax authority
directly due to the amount withholding tax paid by Nintendo, it will promptly
reimburse Nintendo such amount that it has had reduced or received from the tax
authority. Upon request, MoSys shall promptly provide Nintendo, with a copy of
all its relevant tax documents and filings as authorized by the appropriate tax
authority or authorities. For purposes of this Section 3.4, the parties
acknowledge that Nintendo intends to take delivery of all High Density 1T-SRAM
Memories and other related products in

                                       6
<PAGE>

Japan. When and if applicable, MoSys shall timely execute and deliver to NCL, a
tax form in the form which is attached hereto as EXHIBIT D.

       3.5    LATE PAYMENT. Any payments due under this Agreement which are not
paid when due shall bear interest to the extent permitted by applicable law at
the prime rate as reported by the Chase Manhattan Bank, New York, New York, on
the date such payment is due, plus an additional three percent (3%), calculated
on the number of days such payment is delinquent. This Section 3.5 shall in no
way limit any other remedies available to any Party. In the event that Fees are
not timely paid under this Agreement, MoSys shall have no obligation to waive
the applicable Per Unit Royalties of the Authorized Manufacturer. In the event
that MoSys elects not to waive the Per Unit Royalties it shall notify Nintendo
of this fact.

       3.6    AUDIT RIGHTS. MoSys grants to Nintendo and Nintendo shall have the
right to review and audit any draft and/or final version of any Manufacturer's
Agreement between MoSys and any Authorized Manufacturer. In addition, Nintendo
and MoSys each agree to make and to maintain until the expiration of three (3)
years after the year to which such records pertain, sufficient books, records
and accounts regarding, with respect to Nintendo, its purchase and other
activities in order to calculate and confirm its payment, and with respect to
both Parties, each of their respective confidentiality and other obligations
hereunder. Nintendo and MoSys will each have the right, at its own expense and
not more than once in any calendar year, to have an independent certified public
accountant, or other reasonably acceptable professional, inspect, upon
reasonable notice and during regular business hours, Nintendo's or MoSys's
relevant records and practices to verify, with respect to Nintendo, the accuracy
of Fees paid and compliance with its payment obligations, and with respect to
both Parties, each of their respective confidentiality and other obligations
under the terms of this Agreement. If any such examination discloses a shortfall
in the Fees paid to MoSys hereunder or other non-compliance by either Party with
this Agreement, Nintendo shall reimburse MoSys for the full amount of any such
shortfall and Nintendo or MoSys shall have the right to repeat the examination
in the applicable calendar year. If the amount of underpayment for any period is
more than five percent (5%) Nintendo shall pay MoSys's actual out-of-pocket
costs (including without limitation attorneys' fees and fees paid to the
auditor) of performing the audit with respect to such period.

SECTION 4     PROPRIETARY NOTICES AND MARKETING

       4.1    PROPRIETARY NOTICES. Nintendo shall not remove any trademark,
trade name, mask work notice, patent marking or other proprietary notice from
the High Density 1T-SRAM Memories. As reasonably requested by MoSys, Nintendo
further agrees to apply all applicable mask work, patent, copyright and other
proprietary notices in order to fully preserve and protect MoSys's rights and
remedies under applicable laws.

       4.2    PUBLIC ANNOUNCEMENTS. After execution of this Agreement by both
Parties, MoSys and Nintendo will issue a mutually agreed-upon joint public
announcement stating that MoSys's proprietary embedded 1T-SRAM technology has
been selected by Nintendo as the memory in the graphics chip in the Dolphin
Product. At a mutually agreed later date, contemplated to be no later than the
second Quarter of 2000, MoSys and Nintendo will issue a mutually agreed-upon
joint public announcement stating that Nintendo has selected MoSys's ultra-high
density 1T-SRAM discrete memory devices for use in the Dolphin Product in
addition to the embedded 1T-SRAM memory.

                                       7

such public announcements, and neither will unreasonably withhold its agreement
to a public announcement concerning the foregoing that is proposed by the other.

SECTION 5     CONFIDENTIALITY

       5.1    OBLIGATIONS. The parties have entered into a separate
non-disclosure agreement dated March 23, 1999, and hereby acknowledge and agree
that such confidentiality agreement shall govern and control all confidential

breach within thirty (30) days after receipt of such notice, the non-breaching
Party shall be entitled, in addition to any other rights it may have under this
Agreement or otherwise under law, to terminate this Agreement by giving notice
thereof to the other Party which shall take effect immediately.

       6.3    TERMINATION BY MOSYS. This Agreement may be terminated at any time
by MoSys by providing written notice to Nintendo in the event of a good faith
disagreement regarding the determination of the Purchase Price as set forth in

from the date on which both Parties become aware of the disagreement and are
unable to resolve any disagreement by mutual consent; and (b) if the Parties are
unable to resolve such disagreement, the matter will be submitted to an
independent arbitrator acceptable to both Parties who will review materials from
both Parties and issue a written decision which will be binding on both Parties.

       6.4    TERMINATION BY NINTENDO. This Agreement may be terminated at any
time by Nintendo by providing written notice to MoSys in the event of a
disagreement regarding the design quality of the High Density 1T-SRAM Memories,
which disagreement is not resolved after: (a) thirty (30) days from the date on

acceptable to both Parties who will review materials from both Parties and issue
a written decision which will be binding on both Parties.

       6.5    EFFECT OF TERMINATION OR EXPIRATION. Upon termination or
expiration of this Agreement for any reason, the rights granted under this

       6.6    SURVIVAL. The provisions of Section 3, 4.1, 5, 6, 7, 8 and 9 shall
survive the termination or expiration of this Agreement for any reason. It is
expressly understood and agreed that, notwithstanding anything to the contrary
herein, any compensation or payment obligations accruing under Section 3 above
prior to termination, shall continue unaffected and survive termination of this
Agreement for any reason.

SECTION 7     CUSTOMER SUPPORT, WARRANTIES AND INDEMNIFICATION

       7.1    GENERAL. Except as provided in this Agreement and this Section 7,
Nintendo shall be solely responsible for obtaining desired warranties and
indemnification directly from the applicable Authorized Manufacturer rather than
from MoSys. Except for warranties and indemnification so obtained, Nintendo
shall be solely responsible for the representations and warranties that it
provides with respect to the High Density 1T-SRAM Memories. MoSys shall have no
obligation to honor any such representations or warranties, and Nintendo agrees
to expressly disclaim on MoSys's behalf any and all warranties, whether express,
implied, statutory or otherwise. Except for support and maintenance obtained by
Nintendo directly from the Authorized Manufacturer, Nintendo shall be solely
responsible for providing support and maintenance to its customers. MoSys's sole
obligation, responsibility and liability shall be directly to the Authorized
Manufacturer in accordance with the Manufacturer's Agreement

       7.2    MOSYS REPRESENTATIONS AND WARRANTIES. MoSys represents and
warrants to Nintendo that as of the Effective Date:

       (a)    to the best of MoSys's knowledge, it is the originator and/or
rightful owner of the MoSys Intellectual Property and the design information and
documentation of the High Density 1T-SRAM Memory provided to Nintendo pursuant
to the terms of this Agreement (hereinafter collectively "INFORMATION");

       (b)    there are no claims pending or, to the best of MoSys's knowledge,
threatened against MoSys, that relate to the Information or the contemplated use
of the Information by Nintendo and/or any Authorized Manufacturer under this
Agreement;

       (c)    it has received no written communication from a third party
asserting infringement or alleging infringement of their intellectual property
rights regarding 1T-SRAM memory technology which has not been resolved; and

       (d)    it has the full right and authority to enter into and perform any
and all applicable provisions of this Agreement and that there are no
encumbrances or other restrictions that may prevent MoSys or its employees from
performing any and all applicable provisions of this Agreement.

       7.3    INFRINGEMENT. Except as expressly provided herein, MoSys disclaims
and shall have no obligation of defense, contribution, or indemnity with respect
to any actual or alleged intellectual property infringement with respect to the
Information provided or otherwise arising out of this Agreement. Except as
expressly provided herein, MoSys shall have no liability arising out of any such
actual or alleged intellectual property infringement. Each Party, however, will
use commercially reasonable efforts to notify the other Party, in writing, of
any such infringement claim of which it becomes aware, and Nintendo shall
cooperate with MoSys if MoSys desires to intervene

                                       9
<PAGE>

in any such infringement action by any third party against Nintendo, provided,
however, that MoSys shall have no control or right to control the defense of any
such infringement action unless it assumes full responsibility and liability for
such infringement action.

       7.4    LIMITATION OF CLAIMS. In the event of any claim by a third party
for alleged infringement by Nintendo of the third party's intellectual property
rights where such claim (i) is caused substantially by the unmodified High
Density 1T-SRAM Memories and, (ii) is not associated with standard DRAM
operations, processes, design or manufacturing then MoSys shall use its
commercially reasonable efforts at MoSys's sole expense to provide assistance,
including appropriate documentation and commercially reasonable access to
appropriate technical personnel, to Nintendo, in Nintendo's defense against such
claim under this provision. If pursuant to such a claim Nintendo is or may
become prohibited from using the High Density 1T-SRAM Memories, MoSys shall use
commercially reasonable efforts to modify the design of the High Density 1T-SRAM
Memories to avoid any infringement without impairing the ability to use the High
Density 1T-SRAM Memories as intended. In addition, if pursuant to such a claim
Nintendo is or may become prohibited from using the High Density 1T-SRAM
Memories, MoSys shall use commercially reasonable efforts to provide assistance,
including appropriate documentation and commercially reasonable access to
appropriate technical personnel, to Nintendo at rates to be agreed between the
Parties to assist Nintendo at Nintendo's sole expense in either replacing the
High Density 1T-SRAM Memories with compatible, functionally equivalent
non-infringing devices or securing the right to continue using the High Density
1T-SRAM Memories.

       7.5    LIMIT OF LIABILITY. The foregoing states MoSys's sole obligations
and entire liability with respect to any claimed infringement of the High
Density 1T-SRAM Memories of any intellectual property or other rights of any
third party.

       7.6    DISCLAIMERS.

       (a)    EXCEPT AS PROVIDED IN THIS AGREEMENT, THE WARRANTIES AND
INDEMNIFICATIONS OBTAINED BY NINTENDO DIRECTLY FROM THE AUTHORIZED MANUFACTURER
CONTAIN THE ENTIRE LIABILITY AND OBLIGATIONS OF MOSYS, AND THE EXCLUSIVE REMEDY
OF NINTENDO AND ITS CUSTOMERS, WITH RESPECT TO ANY ALLEGED OR ACTUAL
INFRINGEMENT OF PATENTS, MASK WORKS, TRADE SECRETS, COPYRIGHTS, OR OTHER
INTELLECTUAL PROPERTY RIGHTS BY THE HIGH DENSITY 1T-SRAM MEMORIES PRODUCED BY
THE AUTHORIZED MANUFACTURERS.

       (b)    EXCEPT AS PROVIDED IN THIS AGREEMENT, MOSYS MAKES NO
REPRESENTATIONS OR WARRANTIES OF ANY KIND AND NO REPRESENTATIONS OR WARRANTIES
SHALL BE MADE ON BEHALF OF MOSYS, WHETHER EXPRESS, IMPLIED, STATUTORY, OR
OTHERWISE, AND MOSYS SPECIFICALLY DISCLAIMS ANY IMPLIED WARRANTY OF
MERCHANTABILITY, NON-INFRINGEMENT OR FITNESS FOR A PARTICULAR PURPOSE.

SECTION 8     LIMITATION OF LIABILITY

       8.1    EXCEPT TO THE EXTENT EXPRESSLY SET FORTH IN THIS AGREEMENT, MOSYS
SHALL HAVE NO OBLIGATION, RESPONSIBILITY OR LIABILITY ARISING OUT OF OR
RESULTING FROM THE HIGH DENSITY 1T-SRAM MEMORY OR THE PURCHASE

<PAGE>

OR USE OF HIGH DENSITY 1T-SRAM MEMORIES PRODUCED BY THE AUTHORIZED
MANUFACTURERS. THE TOTAL LIABILITY OF MOSYS ARISING OUT OF OR RELATED TO THIS
AGREEMENT SHALL NOT EXCEED THE TOTAL AMOUNT PAID BY NINTENDO TO MOSYS HEREUNDER
(AT THE TIME LIABILITY IS DETERMINED AND LIQUIDATED) AND THE LIABILITY RELATING
TO SPECIFIC PRODUCT(S) PROVIDED HEREUNDER SHALL NOT EXCEED THE TOTAL AMOUNT PAID
BY NINTENDO TO MOSYS FOR SUCH PRODUCT(S) (AT THE TIME LIABILITY IS DETERMINED
AND LIQUIDATED). IN NO EVENT SHALL EITHER PARTY HAVE ANY LIABILITY FOR ANY
INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES, HOWEVER CAUSED AND ON
ANY THEORY OF LIABILITY, WHETHER FOR BREACH OF CONTRACT, TORT (INCLUDING
NEGLIGENCE) OR OTHERWISE, ARISING OUT OF OR RELATED TO THIS AGREEMENT, OR FOR
COST OF PROCUREMENT OF SUBSTITUTE GOODS OR LOSS OF ANTICIPATED PROFITS, EVEN IF
THE PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THESE LIMITATIONS
SHALL APPLY NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED
REMEDY.

SECTION 9     GENERAL PROVISIONS

       9.1    ASSIGNMENT. Neither Party may assign or transfer this Agreement or
any rights or obligations hereunder, by operation of law or otherwise, without
the prior written approval of the other Party and any such attempted assignment

transfer this Agreement to an affiliate, subsidiary, or a successor to all or
substantially all of its business or assets to which this Agreement relates,
whether by way of merger, acquisition of stock or assets, or the like, if the
assignee agrees in writing to comply with all terms and conditions of this
Agreement. Notwithstanding the foregoing, if the assignee is a competitor of
MoSys or Sony Computer Entertainment Company or Sega Corporation, then the
assignment requires the prior written approval of the other Party. Subject to
the foregoing, this Agreement shall be binding upon and inure to the benefit of
the Parties, their successors and permitted assigns.

Notices shall be deemed effective upon receipt or, if delivery is not effected
by reason of some fault of the addressee, when tendered.

       9.3    EXPORT REGULATIONS. Nintendo understands that MoSys is subject to
regulation by the United States government, including, but not limited to, the
U.S. Department of Commerce and its other agencies, which prohibit export or
diversion of certain technical products and information to certain countries and
individuals.

       9.4    GOVERNING LAW. This Agreement, and all disputes arising out of or
relating to this Agreement, shall be governed and construed under the laws of
the State of Washington, U.S.A, without reference to conflict of laws
principles. The United Nations Convention on the International Sale of Goods
shall not apply.

       9.5    DISPUTE RESOLUTION. In the event of any dispute, controversy or
difference which may arise between the parties hereto out of or in connection
with or in relation to this Agreement, or the breach thereof, the parties hereto
shall in the first instance do their utmost to settle such dispute, controversy
or difference amicably.

       9.6    RELATIONSHIP OF THE PARTIES. The Parties are independent
contractors. Nothing in this Agreement shall constitute, nor shall any party
represent that there is any relationship of employee and employee, principal and
agent, partnership or joint venturers between the parties as a result of this
Agreement.

       9.7    SEVERABILITY. If, for any reason, a court or other body of
competent jurisdiction finds, or the Parties mutually believe, any provision of
this Agreement, or portion thereof, to be invalid or unenforceable, such
provision will be enforced to the maximum extent permissible and the remainder
of this Agreement will continue in full force and effect if the resulting
Agreement effects the original intent of the Parties. The Parties shall
negotiate in good faith toward an enforceable substitute provision that most
nearly achieves the intent and economic effect of the invalid or unenforceable
provision.

       9.8    FORCE MAJEURE. Other than the payment of money, nonperformance of
either Party shall be excused to the extent that performance is rendered
commercially unreasonable by acts of God, war, fire, flood, riot, power failure,
embargo, material shortages, strikes, governmental acts, man-made or natural
disasters, earthquakes, inability to obtain labor or materials through its
regular sources, failure or limitation of supply, or any other reason where
failure to perform is beyond the reasonable control and not caused by the
negligence of the non-performing Party. The time for performance shall be
extended for the time period lost due to the delay.

       9.9    WAIVER. The waiver of, or failure to strictly enforce, any breach
or default hereunder shall not constitute the waiver of any other or subsequent
breach or default or the rights of the Party to subsequently require strict
performance.

hereto, the Non-Disclosure Agreement dated March 23, 1999, and the letter
regarding this Agreement signed contemporaneously herewith, which are all
incorporated herein by reference, sets forth the entire agreement between the
parties and supersedes, merges, and renders void any and all prior and
contemporaneous proposals, agreements, and representations between them, whether
written or oral, to the extent they relate in any way to the subject matter
hereof. This Agreement may be changed only by mutual agreement of the parties in
writing.

       9.12   FOREIGN CORRUPT PRACTICES ACT. In conformity with the United
States Foreign Corrupt Practices Act, neither Party nor any of their respective
employees and agents, shall directly or indirectly make any offer, payment, or
promise to pay; authorize payment; nor offer a gift, promise to give, or
authorize the giving of anything of value for the purpose of influencing any act
or decision of an official of any government within the Territory or the United

use his or her influence to affect any such governmental act or decision in
order to assist in obtaining, retaining or directing any business.
