3. LICENSE GRANT AND RESTRICTED USE


3.1 Subject to the terms and conditions stated herein and the acceptance of the
LICENSED PRODUCT, MoSys grants to Licensee and its SUBSIDIARIES a
non-transferable, non-


                                       2


exclusive, royalty-bearing, world-wide, limited license under MOSYS
INTELLECTUAL PROPERTY to use, have used, reproduce, have reproduced, modify and
have modified (to the extent effected by Section 3.2) the LICENSED PRODUCT for
the sole purpose of the design of LICENSED INTEGRATED CIRCUITS, and to
manufacture, have manufactured, use, have used, sell and otherwise distribute
said LICENSED INTEGRATED CIRCUITS. In addition, the Licensee agrees to promptly
inform MoSys in writing at the start of each development in which the LICENSED
PRODUCT will be embedded in a LICENSED INTEGRATED CIRCUIT for projects other
than the Project.

3.2 The modification right granted by MoSys under Section 3.1 above shall be
limited to changes of memory organization, size, density, porting to another
process and minor functional and timing modifications for enhancing the
manufacturability and performance of LICENSED INTEGRATED CIRCUITS and shall only
be made by employees of Licensee and its SUBSIDIARIES at the LICENSED SITES.
Licensee and its SUBSIDIARIES may use subcontractors in exercising the
modification right granted by MoSys under Section 3.1 above with a prior
approval of MoSys, which approval shall not be unreasonably withheld.

3.3 None of the LICENSED PRODUCT or portion thereof may be distributed except to
third party entities as needed to support the manufacturing of the LICENSED
INTEGRATED CIRCUIT. Except as specifically set forth herein, none of the
LICENSED PRODUCT may be disclosed to third parties or transferred outside of
LICENSED SITE(S).

3.4 Licensee acknowledges and agrees that unauthorized use of the LICENSED
PRODUCT which is not expressly authorized by this Section 3 is a breach of a
material obligation of this Agreement. In the event that unauthorized use of
LICENSED PRODUCT by Licensee, its SUBSIDIARIES, or its/their personnel or third
party entities occurs, and MoSys elects not to terminate this Agreement pursuant
to Section 10, Licensee shall by virtue of such act(s) be deemed to order and
accept a license for and shall pay MoSys the list price and applicable royalties
for each such unauthorized use of the LICENSED PRODUCT. These fees shall be
MoSys' published list prices and applicable royalties existing on the date such
unauthorized use first occurred. Such fees and applicable royalties shall be due
no later than thirty (30) days following mutual agreement of the parties with
respect to such unauthorized use.

3.5 Licensee shall mark all catalogues, brochures and other marketing material
used for the LICENSED INTEGRATED CIRCUITS with the MoSys trademark and copyright
notations that appear on or in the LICENSED PRODUCT. As for the LICENSED
INTEGRATED CIRCUITS for the Project, Licensee shall visibly mark each LICENSED
INTEGRATED CIRCUIT with said MoSys copyright notation, providing it is
reasonable and practical to do so but in any event at least to the same extent
that Licensee so marks its own copyright notations. However, the parties
acknowledge and agrees that, in the event that (i) Nintendo Co., Ltd. requests
Licensee not to mark such LICENSED INTEGRATED CIRCUIT with said MoSys copyright
notation or that (ii) the marking of said MoSys copyright notation is impossible
or reasonably impracticable, Licensee will not be required to mark such LICENSED
INTEGRATED CIRCUIT with said MoSys copyright notation under this Section 3.5.


                                       3


3.6 MoSys strictly prohibits the use of the LICENSED PRODUCT in a LICENSED
INTEGRATED CIRCUIT that is designed and used primarily as a stand-alone memory
integrated circuit.

3.7 The licenses granted under this Section 3 are non-sublicenseable.


     4. SUPPORT CONDITION, SILICON DEBUGGING AND PRODUCT ENGINEERING

4.1 In consideration for the technical support and maintenance fees described in
Appendix D, MoSys will provide Licensee with the technical support and
maintenance described in Appendix D for the LICENSED PRODUCT after the
expiration of the warranty period as set forth in Section 13. Except as
expressly specified in this Agreement, such technical support and maintenance is
available on an annual basis only, and MoSys reserves the right to change the
technical support and maintenance fees upon prior notice for any subsequent
annual period.

4.2 The design and verification techniques for the LICENSED PRODUCT used by
MoSys depend on the accuracy of models, flows and design tools; some of which
are provided by MoSys' licensees and their target foundries. Due to practical
limits on the accuracy of these models, flows and design tools, the fabricated
silicon behavior may not always agree with that predicted. In these cases, MoSys
will assist Licensee in silicon debugging and product engineering provided that
Licensee agrees to pay mutually agreed fees to MoSys within thirty (30) days
after the receipt of a relevant invoice to be issued by MoSys. Silicon debugging
and associated product engineering does not fall under the technical support and
maintenance set forth in Section 4.1 above. To the extent MoSys provides any
silicon debugging or product engineering, or otherwise provides Licensee or its
SUBSIDIARIES with any revisions and/or enhancements to the LICENSED PRODUCT,
except as otherwise agreed upon, such revisions and/or enhancements shall be the
LICENSED PRODUCT and subject to the terms and conditions of this Agreement.


5. TERM

This Agreement is effective as of the Effective Date and shall remain in full
force and effect for a period of five (5) years, unless earlier terminated as
provided in this Agreement. Unless earlier terminated as provided in this
Agreement, this Agreement will automatically renew at the end of each term for
consecutive one (1) year renewal periods, unless either party notifies the other
at least sixty (60) days prior to the end of the then current term that it does
not desire the Agreement to renew for another year.


6. CHANGES

6.1 Except as otherwise agreed by both parties in writing, all LICENSED PRODUCTS


                                       4


provided to Licensee by MoSys during the term of this Agreement will be subject
to the terms and conditions of this Agreement.

6.2 Changes to the scope of work either requested by and/or necessitated by
Licensee's specifications will be evaluated for both schedule and cost impact.
The Licensee will be asked to complete an Engineering Change Order Request Form,
an "ECO" and submit it to MoSys for review. If after review by MoSys, it is
determined that both the schedule and/or quoted sales prices must change to
accommodate the ECO, MoSys will notify the Licensee in writing on our ECO
Response Form of any such schedule and/or price changes. Licensee must provide
written acceptance or refusal of the new schedule and/or costs within ten (10)
working days of Licensee's receipt of such notice. Failure to do so will cause
MoSys to proceed with the project as if the "Licensee" ECO Request Form had
never been received. Sample ECO Request and ECO Response Forms are attached as
Exhibits A and B.


7. COMPENSATION

7.1 Except as expressly provided herein, all payments made by Licensee to MoSys
hereunder shall be non-refundable and non-creditable.

7.2 In consideration of the development work of the LICENSED PRODUCT and the
rights and licenses granted to Licensee and its SUBSIDIARIES under this
Agreement Licensee shall pay to MoSys the amounts as set forth in Appendix E in
accordance with the payment schedule as set forth in Appendix E. The foregoing
provisions of this Section 7.2 shall not limit the provisions of Section 3.4
above. Each installment of Prepaid Royalties shall be due within thirty (30)
days after receipt by Licensee of a relevant invoice to be issued by MoSys after
the completion of each milestone as set forth in Appendix E. Prepaid Royalties
may be used to offset against future Royalties of any LICENSED PRODUCT for the
Project due under this Agreement.

7.3 In consideration of the rights and licenses granted to Licensee and its
SUBSIDIARIES under this Agreement, Licensee shall pay to MoSys the running
royalty as set forth in Appendix E and expressed as a percentage of the NET
SALES of all LICENSED INTEGRATED CIRCUITS sold directly or indirectly by
Licensee and/or its SUBSIDIARIES. In the event that LICENSED INTEGRATED CIRCUITS
are sold in circumstances in which the selling price is established other than
on an arms-length basis or as a portion of a bundled products, the NET SALES for
each such integrated circuit shall be calculated based on the volume of such
integrated circuit multiplied by the average gross selling price earned by
Licensee and/or its SUBSIDIARIES during such quarter on sales of that integrated
circuit in finished and packaged form in arms-length sales transactions. If
there are no such arms-length sales transactions, then the parties shall use
such average gross selling price of integrated circuits in finished and packaged
form with similar functionality. It is understood and agreed by the parties
that, at most, only one royalty shall be payable with respect to each LICENSED
INTEGRATED CIRCUIT. The parties agree that no royalty shall accrue for any
LICENSED INTEGRATED CIRCUITS shipped as a replacement for defective LICENSED
INTEGRATED CIRCUITS or furnished by


                                       5


Licensee and/or its SUBSIDIARIES for small quantity sample shipments without
charge to their customers.

7.4 Within thirty (30) days after the expiration of the warranty period
described in Section 13, Licensee further shall pay to MoSys the technical
support and maintenance fees set forth in Appendix E to cover the initial twelve
(12) month period after the expiration of the warranty period. The technical
support and maintenance fees for subsequent twelve (12) month periods under this
Agreement shall be due within thirty (30) days after the beginning of each such
twelve (12) month period.


8. PAYMENT TERMS AND TAXES

8.1 All invoices will be mailed to Licensee's address specified in Section 20,
unless specified otherwise by Licensee.

8.2 Within [*] after the end of each calendar quarter, Licensee shall pay to
MoSys the running royalties set forth in Section 7.3 and Appendix E with
respect to the LICENSED INTEGRATED CIRCUITS manufactured and sold in such
calendar quarter, and shall submit to MoSys with such royalty payment a
report stating the number for each LICENSED INTEGRATED CIRCUIT manufactured
and sold during such calendar quarter and the applicable running royalties
payable hereunder for such calendar quarter; and all reasonably necessary
data and supporting calculations used by Licensee and/or its SUBSIDIARIES to
compute the running royalties payable by Licensee to MoSys with respect to
such calendar quarter.

8.3 Any and all amounts 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 Licensee 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 Licensee's invoice and paid by Licensee,
unless Licensee provides MoSys with a valid tax exemption certificate authorized
by the appropriate taxing authority.

8.4 All payments by Licensee 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 Licensee. If any applicable law requires Licensee to
withhold amounts from any payments to MoSys hereunder, (i) Licensee 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 Licensee 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


                                       6


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 Licensee, it will reimburse Licensee such amount that it has had reduced
or received from the tax authority.

8.5 With respect to LICENSED INTEGRATED CIRCUITS and non-recurring engineering
fees, royalties and other amounts which are payable to MoSys under this
Agreement, as a material condition to this Agreement, Licensee shall keep
complete and accurate books and records, to the extent reasonably necessary for
MoSys to ascertain the accuracy of the royalty reports to be furnished
hereunder. These books and records shall be retained for a period of three (3)
years from the date of the last day of each calendar quarter period,
notwithstanding the expiration or termination of this Agreement. As a material
condition to this Agreement, Licensee agrees to permit these books and records
to be examined by an independent firm, experienced in conducting such an
exercise, designated by MoSys and approved by Licensee (such approval shall not
be unreasonably withheld), subject to the confidentiality provisions set forth
in this Agreement and at a time and place convenient to both parties, but during
normal business hours and not more frequently than annually, to verify the
accuracy of royalties and other amounts paid to MoSys under this Agreement.
Adjustment shall be made by Licensee corresponding to the net amount of any
underpayment of any and all royalties and other amounts disclosed by such
examination within thirty (30) days after Licensee's receipt of a relevant
invoice issued by MoSys therefor. The net amount of any overpayment of any and
all royalties and other amounts disclosed by such examination shall be credited
by MoSys against subsequent royalties to be paid by Licensee to MoSys. If such
an examination reveals an underpayment of more than five percent (5%), then
Licensee shall promptly reimburse MoSys for the cost of such examination.

8.6 All payment amounts stated hereunder, and all payments to be made hereunder,
shall be in U.S. Dollars and shall be transmitted by telegraphic transfer to
MoSys' bank account designated by MoSys in writing in advance. If any currency
conversion shall be required in connection with the calculation of amounts
payable under this Agreement, such conversion shall be made using the TTS rate
for conversion of the foreign currency into U.S. Dollars, published by the Bank
of Tokyo-Mitsubishi, Ltd. for the last business day of the calendar quarter to
which such payment pertains.


9. EXPORT RESTRICTIONS

This Agreement, the LICENSED PRODUCT(S) and the rights granted hereunder are
subject to any and all laws, regulations, orders or other restrictions relative
to export, re-export or redistribution of the LICENSED PRODUCT(S) that may now
or in the future be imposed by the government of the United States or foreign
governments. Licensee agrees to comply with all such applicable laws and

10.1 (a) If either party defaults in the performance of any material obligation
hereunder and if any such default is not corrected within forty-five (45) days
after the defaulting party receives written notice thereof from the
non-defaulting party, then the non-defaulting party, at its option, may, in
addition to any other remedies it may have, terminate this Agreement. For the
purposes of this section, each of Licensee's obligations pursuant to Sections 3,
7 and 8 above and each of MoSys' obligations pursuant to Sections 2,4,13 and 14
and both parties obligations pursuant to Section 16 shall be considered
material.

     (b) Either party may terminate this Agreement effective upon receipt of
written notice by the other party in the event that the other party becomes the
subject of a voluntary or involuntary petition in bankruptcy or any proceeding
relating to insolvency, or the assignment for the benefit of creditors, if that
petition or proceeding is not dismissed within ninety (90) days after filing.

10.2 Upon any termination or expiration of this Agreement, all licenses and
rights granted by MoSys shall terminate, and Licensee shall promptly destroy or
deliver to MoSys all materials comprising, incorporating, or using any MOSYS
INTELLECTUAL PROPERTY or any LICENSED PRODUCTS, provided, however, that if this

disclosing party; (iii) becomes publicly available or otherwise ceases to be
secret or confidential, except through a breach of this Agreement by the
recipient; (iv) was independently developed by the recipient without access to
the disclosing party's Confidential Information; (v) is required to be disclosed
pursuant to any statutory or regulatory authority, provided the disclosing party
is given prompt notice of such requirement and the scope of such disclosure is
limited to the extent possible; (vi) is required to be disclosed by a court
order, provided the disclosing party is given prompt notice of such order and
provided the opportunity to contest it, and/or is reasonably necessary to
disclose in order to enforce this Agreement; or (vii) is residual information in
the minds of employees having had access to Confidential Information (provided
not deliberately memorized) after a period of five years.

Notwithstanding any of the foregoing, Licensee agrees not to disclose any
Confidential Information of Licensee to MoSys unless MoSys requests disclosure
of such information in writing.

16.4 As to each item of Confidential Information, the provisions of this Section
will continue for three (3) years following first receipt of such information,
except for the LICENSED PRODUCT, for which the provisions of this Section will
continue for five (5) years following any termination or expiration of this
Agreement.
