notations that appear on or in the LICENSED PRODUCT. NEC shall also visibly mark
each HIGH DENSITY 1T-SRAM MEMORY 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 NEC so marks its own copyright notations. However, the parties
acknowledge and agrees that, in the event that the marking of said MoSys
copyright notation is impossible or reasonably impracticable, NEC will not be
required to mark such HIGH DENSITY 1T-SRAM MEMORY with said MoSys copyright
notation. In the event that an end-customer for the HIGH DENSITY 1T-SRAM MEMORY
requires that the markings be removed from the HIGH DENSITY 1T-SRAM MEMORY
devices, NEC and MoSys shall discuss in good faith how they might accommodate
this requirement, while still satisfying MoSys' marketing goals and needs to
protect ownership of its intellectual property.

In the event that HIGH DENSITY 1T-SRAM MEMORIES 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 NEC 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 HIGH DENSITY 1T-SRAM MEMORY. The parties agree that
no royalty shall accrue for any HIGH DENSITY 1T-SRAM MEMORIES shipped as a
replacement for defective HIGH DENSITY 1T-SRAM MEMORIES or furnished by NEC

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 HIGH DENSITY 1T-SRAM MEMORY (other than taxes on the
net income of MoSys), and NEC 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 NEC's invoice and paid by NEC, unless
NEC provides MoSys with a valid tax exemption certificate authorized by the
appropriate taxing authority.

8.4 All payments by NEC 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 NEC. If any applicable law requires NEC to withhold
amounts from any payments to MoSys hereunder, (i) NEC 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 NEC 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 NEC, it will
reimburse NEC such amount that it has had reduced or received from the tax
authority.

8.5 As a material condition to this Agreement, NEC shall keep complete and
accurate records and books of account relating to sales of HIGH DENSITY 1T-SRAM
MEMORY to customers, to the extent reasonably necessary for MoSys to ascertain

termination of this Agreement. As a material condition to this Agreement, upon
receiving thirty (30) days prior written notice from MoSys, NEC agrees to permit
these books and records to be

                                       8
<PAGE>

examined by an independent firm, experienced in conducting such an exercise,
designated by MoSys and approved by NEC (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
paid to MoSys under this Agreement, if any. Adjustment shall be made by NEC
corresponding to the net amount of any underpayment of any and all royalties
disclosed by such examination within thirty (30) days after NEC's receipt of a
relevant invoice issued by MoSys therefor. The net amount of any overpayment of
any and all royalties disclosed by such examination shall be credited by MoSys
against subsequent royalties to be paid by NEC to MoSys. If such an examination
reveals an underpayment of more than five percent (5%), then NEC 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.

         rights to NEC and its SUBSIDIARIES shall be implied from the provisions
         stated herein.

13.2     MoSys represents and warrants as of the Effective Date:

     (a) to the best of MoSys' knowledge, it is the originator and/or rightful
         owner of the product(s), information and documentation provided to NEC
         pursuant to the terms of this Agreement (including, not limited to,
         LICENSED PRODUCT) (hereinafter collectively " Information"); and

     (b) to the best of MoSys' knowledge, there are no claims pending or
     threatened against MoSys or any other party, that relate to the Information
     or the contemplated use of the Information under this Agreement.

13.3 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.

                                       11
<PAGE>

MoSys shall have no liability arising out of any such actual or alleged
intellectual property infringement. NEC, however, will use its reasonable
efforts to notify MoSys, in writing, of each such infringement claim of which
NEC becomes aware, and NEC shall cooperate with MoSys if MoSys desires to
intervene in any such infringement action against NEC.

13.4 In the event of any claim by a third party of infringement of its
intellectual property rights by the NEC and/or its SUBSIDIARIES where such claim
(i) is caused substantially by the unmodified LICENSED PRODUCT and, (ii) is not
associated with standard DRAM operations, processes, design or manufacturing
then MoSys agrees to use reasonable efforts at MoSys' expense to provide
assistance, including appropriate documentation, to NEC, in its defense against
such claim under this provision. If pursuant to such a claim NEC and/or its
SUBSIDIARIES are prohibited from using the LICENSED PRODUCTS, MoSys agrees to
use reasonable efforts to modify the LICENSED PRODUCTS to avoid the
infringement.

13.5 The foregoing states MoSys' sole obligations and entire liability with
respect to any claimed infringement of the LICENSED PRODUCT(S) of any
intellectual property or other rights of any third party.

14. LIMITATION OF LIABILITY

IN NO EVENT WILL MOSYS' LIABILITY ARISING OUT OF THIS AGREEMENT EXCEED THE FEES
AND ROYALTIES, IF ANY, RECEIVED BY MOSYS' HEREUNDER. EXCEPT FOR INFRINGEMENT OF
THE OTHER PARTY'S INTELLECTUAL PROPERTY RIGHTS, 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
OR THE DESIGNS, TECHNOLOGY OR PRODUCT LICENSED OR OTHERWISE PROVIDED PURSUANT TO
THIS AGREEMENT.

standard product literature. Neither party shall announce or publicly disclose
any other terms or conditions of this Agreement without a prior written approval
from the other party. An initial public announcement plan and contents are

information and materials which are provided by one party to the other party (i)
in written or other tangible form clearly marked with a legend identifying it as
"Confidential" or "Proprietary" or (ii) in oral or visual form identified as
"Confidential" or "Proprietary" at the time of such oral or visual disclosure
and within thirty (30) days following such oral or visual disclosure the summary
of which is provided to the other party in written or other tangible form marked
with such legend. Each party agrees that except as may otherwise be stated
herein, it shall not use, except to perform its obligations and/or to exercise
its rights and licenses specified under this Agreement, nor disclose to any
third party (except to Nintendo, ArtX, Inc. and recipient's independent
contractors and affiliates (including SUBSIDIARIES) who are under an obligation
of confidentiality, and subject to the other terms and conditions of this
Agreement), any such Confidential Information revealed to it by the other party.
Each party shall take reasonable precautions to protect the confidentiality of
such information, which in any event will be no less than what it takes with
respect to its own similar confidential information.

15.3 Information shall not be deemed Confidential Information hereunder if such
information: (i) is known to the recipient at the time of disclosure; (ii)
hereafter becomes rightfully known to the recipient (as for NEC, including
Nintendo) directly or indirectly from a third party without such third party
imposing an obligation of confidentiality on the 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 (as for NEC, including Nintendo) 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; or (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.

Notwithstanding any of the foregoing, NEC agrees not to disclose any
Confidential Information of NEC to MoSys unless MoSys requests disclosure of
such information in writing (including e-mail).

15.4 Recipient may make copies, in whole or in part, of disclosing party's
Confidential Information only to the extent necessary for the use thereof by
recipient in accordance with Section 15.2 above, provided recipient shall
reproduce and include disclosing party's proprietary and confidentiality notice
on each such copy.

15.5 As to each item of Confidential Information, the provisions of this Section
will continue for five (5) years following first receipt of such information,
except for the LICENSED PRODUCT, for which the provisions of this Section will
continue for eight (8) years following first receipt of each LICENSED PRODUCT.

15.6 This Agreement and the terms of confidentiality hereunder shall not be
construed to limit any party's right to independently develop or acquire
products or technology, including similar or competing products or technology,
without the use of the other party's Confidential

                                       13
<PAGE>

Information.

Notwithstanding anything contained in this Section and the Agreement, any party
shall be free to use for any purpose the residuals resulting from access to or
work with the Confidential Information, provided that such party shall maintain
the confidentiality of the Confidential Information as provided herein. For the
purposes of this Agreement, the term "residuals" means information in
non-tangible form, which may be retained in the minds of employees, provided not
deliberately memorized, who have had access to such Confidential Information,
including ideas, concepts, know-how or techniques contained therein. No party
shall have any obligation to limit or restrict the assignment of such employees
or to pay royalties for any work resulting from the use of residuals. However,
the foregoing shall not be deemed to grant to any party a license under the
other party's copyrights or patents.

17.2 Where the parties hereto fail to settle such dispute, controversy or
difference amicably within ten (10) working days of the written notice of its
existence given by either party to the other party, then the dispute,
controversy or difference shall be finally settled by arbitration in Santa
Clara, California, U.S.A. in accordance with the Rules of Conciliation and
Arbitration of the International Chamber of Commerce. The award of arbitration
shall be final and binding upon the parties hereto and shall not be subject to
appeal to any court, and may be entered into the court of competent jurisdiction
for its execution forthwith.

Mr. F. Judson Mitchell
159 El Pinar
Los Gatos, CA 95032
Tel: (408) 379-8472

Dear Judd,

         I am pleased to offer you a position with Monolithic System Technology,
Inc. ("MoSys" or the "Company") as its Chief Financial Officer, an exempt
position, commencing on or before July 22, 2000. Your supervisor will be myself.
Your base compensation will be one hundred seventy five thousand dollars
($175,000) annually.

         Upon approval of the Company's Board of Directors, you will be granted
an option to purchase 250,000 shares of the Company's common stock. The terms of
such option shall be in accordance with the terms of the Company's stock option
plan. Accordingly, the option will vest 25% at the end of one year of employment
and 2% per month thereafter. The per share exercise price of the option shall be
the fair market value of the Company's common stock on the date of grant as
determined by the Company's Board of Directors, currently deemed to be $8.00 per
share.

         If (i) there is an event of change of control of more than 50% of the
voting power of the Company resulting from a merger, reorganization, sale of all
or substantially all assets or other similar acquisition transaction, and (ii)
you are terminated without Cause or Constructively Terminated (as such terms are
defined below) in connection with such change in control event or during the
twelve month period thereafter, then all unvested stock options granted to you
above shall be immediately accelerated and exercisable.

         "Cause" shall mean (i) an intentional material act of fraud or
dishonesty in connection with employee's duties, or in the course of employment
with the company; (ii) the conviction of a felony; (iii) a willful act by
Employee which is injurious to the Company: or (iv) a willful failure by
Employee to substantially perform his duties, other than a failure resulting
from the Employee's complete or partial incapacity due to physical or mental
illness or impairment.

         "Constructively Terminated" shall mean the termination of the
Employee's employment because of (i) an assignment to Employee of any duties
materially inconsistent with or which constitute a material detrimental change
of Employee's position, duties, responsibilities or status or (ii) a material
reduction in Employee's salary.

<PAGE>

         As a Company employee, you are also eligible to receive those employee
benefits that are generally offered to all employees of the Company.

         You should be aware that your employment with the Company is for no
specified period and constitutes at will employment. As a result, you are free
to resign at any time, for any reason or for no reason. Similarly, the Company
is free to conclude its employment relationship with you at any time, with or
without cause.

         Should your employment be terminated without Cause, the Employee will
receive one quarter (1/4) of the annual salary in effect at the time of the
termination as severance pay from the Company.

         In the event of any dispute or claim relating to or arising out of our
employment relationship, you and the Company agree that all such disputes shall
be fully and finally resolved by binding arbitration conducted by the American
Arbitration Association in Santa Clara County, California. However, we agree
that this arbitration provision shall not apply to any disputes or claims
relating to or arising out of the misuse or misappropriation of the Company's
trade secrets or proprietary information.

         To indicate your acceptance of the Company's offer, please sign and
date this letter in the space provided below and return it to me. This letter,
along with the agreement relating to proprietary rights between you and the
Company, set forth the terms of your employment with the Company and supersede
any prior representations or agreements, whether written or oral. This letter
may not be modified or amended except by a written agreement, signed by the
Company and by you.

         We look forward to working with you at MoSys Inc.

                                           Sincerely,

                                           /s/
                                           ----------------------------------
                                           Chief Executive Officer

ACCEPTED AND AGREED TO this 19 day of July 2000.
