2006 (the “Effective Date”).

WHEREAS, subject to the Company’s satisfaction of the result of the CLO’s
background check and the commencement of the “Hire Date” as defined in paragraph
2 below, the Company desires to employ the CLO and the CLO desires to accept
employment with the Company on the terms and conditions set forth below;

NOW, THEREFORE, the parties hereto agree as follows:

1. Certain Definitions. For purposes of this Agreement:

(a) “Cause” means (i) the CLO’s failure to perform the duties or
responsibilities of his employment, in any material respect, as reasonably
required or directed by the Board of Directors of the Company (the “Board”) or
the Chief Executive Officer (the “CEO”) and the President, (or the relevant
supervising officer, manager or board of directors of a successor company),
which failure is not cured within thirty (30) days following notice to the CLO
of the poor performance which notice describes in reasonable detail the poor
performance; (ii) the CLO personally engaging in illegal conduct that is
detrimental to the Company; (iii) the CLO being convicted of a felony; or
(iv) the CLO committing a material act of dishonesty, fraud or misappropriation
of property.

(b) “Good Reason” means, without the CLO’s consent, (i) a reduction by the
Company in the base salary of the CLO as in effect immediately prior to such
reduction, except where a substantially equivalent percentage reduction in base
salary is applied to all other officers of the Company; (ii) a material
reduction by the Company in the kind or level of employee benefits to which the
CLO is entitled immediately prior to such reduction with the result that the
CLO’s overall benefits package is significantly reduced, except where a
substantially equivalent reduction in benefits is applied to all other officers
of the Company; (iii) a material, adverse change in the CLO’s title, authority,
responsibilities or duties, as measured against his title, authority,
responsibilities or duties immediately prior to such change; or (iv) the
relocation of the CLO’s place of work to a facility or a location more than
fifty (50) miles from the CLO’s then-present work location.

(c) “Disability” means the CLO’s inability to substantially perform the CLO’s
duties as required by the CLO’s employment with or services to the Company as
the result of the CLO’s incapacity due to physical or mental illness.

(d) “Change of Control” means any of the following that occurs with respect to
the Company if the stockholders of the Company immediately before such
transaction do not retain

--------------------------------------------------------------------------------

immediately after the transaction, in substantially the same proportions as
their ownership of shares of the Company’s voting stock immediately before the
transaction, direct or indirect beneficial ownership of more than fifty percent
(50%) of the total combined voting power of the outstanding voting stock of the
Company or the corporation or corporations to which the assets of the Company
are transferred:

(i) the direct or indirect sale or exchange in a single or series of related
transactions by the Company or the stockholders of the Company of more than
fifty percent (50%) of the voting stock of the Company;

(ii) a merger or a consolidation in which the Company is a party; or

(iii) the sale, exchange, or transfer of all or substantially all of the assets
of the Company.

2. Employment and Duties. The CLO shall be appointed as Chief Legal Officer &
Corporate Secretary of the Company and report to the Company as of October 2,
2006 (“Hire Date”). The CLO shall report to the Chief Executive Officer (CEO)
and President, and shall assume and discharge such responsibilities as are
mutually agreed upon by the CLO and the CEO or the Board, and consistent with
such office and position. The CLO shall perform faithfully the duties assigned
to her to the best of her ability.

3. Compensation.

(a) In consideration of the CLO’s services, the CLO shall be paid a base salary
at the rate of $225,000 per year during the period of employment (the “Base
Salary”), to be paid in installments in accordance with the Company’s standard
payroll practices. This Base Salary shall be reviewed for increases at least
annually by the Compensation Committee on the same basis and at the same time as
the Compensation Committee shall review the compensation of other executive
officers of the Company including any review for the next fiscal year which has
not yet occurred, but such increases are not guaranteed.

(b) The CLO shall be granted an option under the Company’s 2004 Stock Option
Plan entitling her to purchase 150,000 shares of the Company’s Common Stock (the
“Stock Options”) with vesting over four (4) years, as set forth more fully in
the Stock Options Agreement therefor.

(c) The CLO shall participate in the Company bonus plan. Executive’s annual
target bonus will be payable upon achievement of personal and company specific
performance objectives established by the Board, CEO or the Compensation
Committee of the Board. For the first year only, in no event will the minimum
paid bonus be less than 20% of base salary or $45,000.

4. At-Will Employment. The Company and the CLO acknowledge that the CLO’s
employment is and shall continue at all times to be at-will, as defined under
applicable law. If the CLO’s employment terminates for any reason, the CLO shall
not be entitled to any payments, benefits, damages, awards or compensation other
than as provided by this Agreement, or as may otherwise be available in
accordance with the Company’s established employee plans and policies or other
written agreements with the CLO at the time of termination.

--------------------------------------------------------------------------------

5. Benefits. The CLO, together with his spouse and dependent children, if any,
shall be permitted, to the extent eligible, to participate at the Company’s
expense in any group medical, dental, life insurance and disability insurance
plans, or similar benefit plans of the Company that are available to other
executive officers in each case pursuant to the terms and conditions of each
such plan or program. The CLO shall also be entitled to fifteen days of paid
time off (PTO) annually.

6. Termination for Cause and Voluntary Termination without Good Reason. In the
event that the CLO resigns from the Company without Good Reason, or the Company
terminates the CLO’s employment for Cause, the CLO shall not receive any
compensation or benefits under this Agreement on account of such termination,
except for obligations accrued at such time. The CLO’s rights under any
applicable Company benefit plans upon such termination shall be determined under
the provisions of the respective benefit plans.

7. Termination without Cause and Voluntary Termination with Good Reason. Subject
to Section 10 below, if the Company terminates the CLO’s employment without
Cause, or the CLO resigns from the Company for Good Reason, then the CLO shall
receive severance payments and partial acceleration of the vesting of the Stock
Options (together the “Severance Benefits”) pursuant to sub-sections 7(a) and
(b) below:

(a) Severance Payments. After the date of such termination, the Company shall
continue to pay the CLO at a rate based on his then Base Salary and target
annual bonus, in installments in accordance with the Company’s standard payroll
practices, and will provide the CLO and his dependents full medical benefits,
for a period of six (6) months after the date of such termination; provided;
however, such payments and benefits shall terminate immediately upon the date of
the CLO’s commencement of new employment with another company, and the CLO shall
provide the Company with written notice of his acceptance of new employment
within three (3) days thereof. In the event such termination occurs within one
(1) year following a Change of Control, then such payments and benefits shall
continue for a period of one (1) year after the date of such termination.

(b) Vesting Acceleration. Effective upon such termination, the CLO shall receive
accelerated vesting equivalent to six (6) months of service beyond the date of
his termination with respect to the shares subject to the Stock Options granted
to the CLO; provided, however, that in the event such termination occurs within
one (1) year following a Change of Control, then seventy five percent (75%) of
the remaining shares subject to the Stock Options and any other options grated
to the CLO shall become vested in full and the period during which the CLO is
permitted to exercise such options shall be extended for the full term of such
options, all as set forth more fully in the Stock Option Agreements therefor.

8. Death. In the event of the CLO’s death, except for obligations accrued at
such time, the Company shall have no obligation to pay or provide any
compensation or benefits under this Agreement. The CLO’s rights under the
Company’s benefit plans in the event of the CLO’s death shall be determined
under the provisions of such benefit plans.

--------------------------------------------------------------------------------

9. Disability. In the event of the CLO’s Disability, except for obligations that
have accrued prior to the CLO’s Disability, no compensation or benefits will be
paid or provided to the CLO under this Agreement. The CLO’s rights under the
Company’s benefit plans shall be determined under the provisions of such benefit
plans.

10. Conditional Nature of Severance Benefits.

(a) Noncompete. CLO acknowledges that the nature of the Company’s business is
such that if CLO were to become employed by, or substantially involved in, the
business of a direct competitor of the Company during the six (6) months
following the termination of CLO’s employment with the Company, it would be very
difficult for CLO not to rely on or use the Company’s trade secrets and
confidential information. Thus, to avoid the likely disclosure of the Company’s
trade secrets and confidential information, CLO agrees and acknowledges that
CLO’s right to receive the Severance Benefits set forth above (to the extent
Executive is otherwise entitled to such Severance Benefits) shall be conditioned
upon CLO not directly engaging in (whether as an employee, consultant, agent,
proprietor, principal, partner, stockholder, corporate officer, director or
otherwise), nor having participation in the financing, operation, management or
control of, any person, firm, corporation or business that directly competes
with the Company. “Direct Competitor” shall be defined as a semiconductor
company whose primary revenue is derived from analog products that are sold into
the same customer, application, and end product base as the Company and would be
considered direct competitors by an independent person. Upon any breach of this
Section 10 or Section 13 below, all Severance Benefits to which the CLO may be
entitled, if any, pursuant to this Agreement shall immediately cease.

11. Other Activities. The CLO shall devote substantially all of his working time
and efforts during the Company’s normal business hours to the business and
affairs of the Company and its subsidiaries and to the diligent and faithful
performance of the duties and responsibilities duly assigned to him pursuant to
this Agreement, except for vacations, holidays and sickness. However, the CLO
may devote a reasonable amount of his time to civic, community, or charitable
activities and, with the prior written approval of the Company, to serve as a
director of other corporations and to other types of business or public
activities not expressly mentioned in this paragraph.

12. Proprietary Information. During the period of employment and thereafter, the
CLO shall not, without the prior written consent of the Company, disclose or use
for any purpose (except in the course of his employment under this Agreement and
in furtherance of the business of the Company or any of its affiliates or
subsidiaries) any confidential information or proprietary data of the Company.
The CLO agrees to execute the Company’s form of Proprietary Information
Agreement, which is attached hereto as Exhibit A and incorporated herein by
reference.

13. Covenant Not to Solicit. Beginning with the date of the CLO’s termination
and until one (1) year thereafter, the CLO agrees that he will not:

(i) solicit, encourage, or take any other action which is intended to induce any
other employee of the Company to terminate his employment with the Company, or

--------------------------------------------------------------------------------

(ii) interfere in any manner with the contractual or employment relationship
between the Company and any employee of the Company.

14. Tax Provisions. In the event that the benefits provided for in the
Agreement, when aggregated with any other payments or benefits received by the
CLO, would (i) constitute “parachute payments” within the meaning of
Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), and
(ii) would be subject to the excise tax imposed by Section 4999 of the Code (the
“Excise Tax”), then the CLO’s benefits hereunder shall be either

(a) delivered in full, or

(b) delivered as to such lesser extent which would result in no portion of such
benefits being subject to the Excise Tax,

whichever of the foregoing amounts, taking into account the applicable federal,
state and local income taxes and the Excise Tax, results in the receipt by the
CLO on an after-tax basis, of the greatest amount of benefits, notwithstanding
that all or some portion of such benefits may be taxable under Section 4999 of
the Code. Unless the Company and the CLO otherwise agree in writing, any
determination required under this paragraph shall be made in writing by the
Company’s independent public accountants (the “Accountants”) whose determination
shall be conclusive and binding upon the CLO and the Company for all purposes.
For purposes of making the calculations required by this paragraph, the
Accountants may make reasonable assumptions and approximations concerning
applicable taxes and may rely on reasonable, good faith interpretations
concerning the application of Sections 280G and 4999 of the Code. The Company
and the CLO shall furnish to the Accountants such information and documents as
the Accountants may reasonably request in order to make a determination under
this paragraph.

15. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of California applicable to agreements
made and to be performed entirely within such state, without regard to
principles of conflicts of laws.

16. Integration. This Agreement, any written agreements or other documents
evidencing matters referred to herein and any written Company existing plans
that are referenced herein represent the entire agreement and understanding
between the parties as to the subject matter hereof and thereof and supersede
all prior or contemporaneous agreements as to the subject matter hereof and
thereof, whether written or oral.

17. Notices. Notices and all other communications contemplated by this Agreement
shall be in writing and shall be deemed to have been duly given when personally
delivered or when mailed by U.S. registered or certified mail, return receipt
requested and postage prepaid. In the case of the CLO, mailed notices shall be
addressed to him at the home address that he most recently communicated to the
Company in writing. In the case of the Company, mailed notices shall be
addressed to its corporate headquarters, and all notices shall be directed to
the attention of its CEO.

--------------------------------------------------------------------------------

18. Waiver etc. No waiver, alteration, or modification, if any, of the
provisions of this Agreement shall be binding unless in writing and signed by
duly authorized representatives of the parties hereto. If either party should
waive any breach of any provisions of this Agreement, such party shall not
thereby be deemed to have waived any preceding or succeeding breach of the same
or any other provision of this Agreement.

19. Severability. If any term of this Agreement is held by a court of competent
jurisdiction to be invalid, void or unenforceable, then the remainder of the
terms of this Agreement shall remain in full force and effect and shall in no
way be affected, impaired or invalidated.

20. Counterparts. This Agreement may be executed in counterparts, which together
will constitute one instrument.

MONOLITHIC POWER SYSTEMS, INC.

EMPLOYEE CONFIDENTIAL INFORMATION AND

INVENTION ASSIGNMENT AGREEMENT

Name of Employee: Adriana Guevara Chiocchi

As a condition of my employment with Monolithic Power Systems, Inc., its
subsidiaries, affiliates, successors or assigns (together the “Company”), and in
consideration of my employment with the Company and my receipt of the
compensation now and hereafter paid to me by Company. I agree to the following:

1. At-Will Employment. I understand and acknowledge that my employment with the
Company is for an unspecified duration and constitutes “at-will” employment. I
acknowledge that this employment relationship may be terminated at any time,
with or without good cause or for any or no cause, at the option either of the
Company or myself, with or without notice.

2. Confidential Information.

(a) Company Information. I agree at all times during the term of my employment
and thereafter, to hold in strictest confidence, and not to use, except for the
benefit of the Company, or to disclose to any person, firm or corporation
without written authorization of the Board of Directors of the Company, any
Confidential Information of the Company. I understand that “Confidential
Information” means any Company proprietary information, technical data, trade
secrets or know-how, including, but not limited to, research, product plans,
products, services, customer lists and customers (including, but not limited to,
customers of the Company on whom I called or with whom I became acquainted
during the term of my employment), markets, software, developments, inventions,
processes, formulas, technology, designs, drawings, engineering, hardware
configuration information, marketing, finances or other business information
disclosed to me by the Company either directly or indirectly in writing, orally
or by drawings or observation of parts or equipment. I further understand that
Confidential Information does not include any of the foregoing items which has
become publicly known and made generally available through no wrongful act of
mine or of others who were under confidentiality obligations as to the item or
items involved.

(b) Former Employer Information. I agree that I will not, during my employment
with the Company, improperly use or disclose any proprietary information or
trade secrets of any former or concurrent employer or other person or entity and
that I will not bring onto the premises of the Company any unpublished document
or proprietary information belonging to any such employer, person or entity
unless consented to in writing by such employer, person or entity.

(c) Third Party Information. I recognize that the Company has received and in
the future will receive from third parties their confidential or proprietary
information subject to a

 

Employee’s Initial:

--------------------------------------------------------------------------------

duty on the Company’s part to maintain the confidentiality of such information
and to use it only for certain limited purposes. I agree to hold all such
confidential or proprietary information in the strictest confidence and not to
disclose it to any person, firm or corporation or to use it except as necessary
in carrying out my work for the Company consistent with the Company’s agreement
with such third party.

3. Inventions.

(a) Inventions Retained and Licensed. I have attached hereto, as Exhibit A, a
list describing all inventions, original works of authorship, developments,
improvements, and trade secrets which were made by me prior to my employment
with the Company, which belong to me, which relate to the Company’s proposed
business, products or research and development, and which are not assigned to
the Company hereunder (collectively referred to as “Prior Inventions”); or, if
no such list is attached, I represent that there are no such Prior
Inventions. If in the course of my employment with the Company, I incorporate
into any invention, improvement, development, product, copyrightable material or
trade secret any invention, improvement, development, concept, discovery or
other proprietary information owned by me or in which I have an interest, the
Company is hereby granted and shall have a nonexclusive, royalty-free,
irrevocable, perpetual, worldwide license to make, have made, modify, use and
sell such Prior Invention as part of or in connection with such product, process
or machine.

(b) Assignment of Inventions. I agree that I will promptly make full written
disclosure to the Company, will hold in trust for the sole right and benefit of
the Company, and hereby assign to the Company, or its designee, all my right,
title, and interest in and to any and all inventions, original works of
authorship, developments, concepts, improvements or trade secrets, whether or
not patentable or registrable under copyright or similar laws, which I may
solely or jointly conceive or develop or reduce to practice, or cause to be
conceived or developed or reduced to practice, during the period of time I am in
the employ of the Company (collectively referred to as “Inventions”), except as
provided in Section 3(f) below. I further acknowledge that all original works of
authorship which are made by me (solely or jointly with others) within the scope
of and during the period of my employment with the Company and which are
protectable by copyright are “works made for hire,” as that term is defined in
the United States Copyright Act.

(c) Inventions Assigned to the United States. I agree to assign to the United
States government all my right, title, and interest in and to any and all
Inventions whenever such full title is required to be in the United States by a
contract between the Company and the United States or any of its agencies.

(d) Maintenance of Records. I agree to keep and maintain adequate and current
written records of all Inventions made by me (solely or jointly with others)
during the term of my employment with the Company. The records will be in the
form of notes, sketches, drawings, and any other format that may be specified by
the Company. The records will be available to and remain the sole property of
the Company at all times.

(e) Patent and Copyright Registrations. I agree to assist the Company, or its
designee, at the Company’s expense, in every proper way to secure the Company’s
rights in the

 

Employee’s Initial:  

/s/ AGC

--------------------------------------------------------------------------------

Inventions and any copyrights, patents, mask work rights or other intellectual
property rights relating thereto in any and all countries, including the
disclosure to the Company of all pertinent information and data with respect
thereto, the execution of all applications, specifications, oaths, assignments
and all other instruments which the Company shall deem necessary in order to
apply for and obtain such rights and in order to assign and convey to the
Company, its successors, assigns and nominees the sole and exclusive rights,
title and interest in and to such Inventions, and any copyrights, patents, mask
work rights or other intellectual property rights relating thereto. I further
agree that my obligation to execute or cause to be executed, when it is in my
power to do so, any such instrument or papers shall continue after the
termination of this Agreement. If the Company is unable because of my mental or
physical incapacity or for any other reason to secure my signature to apply for
or to pursue any application for any United States or foreign patents or
copyright registrations covering Inventions or original works of authorship
assigned to the Company as above, then I hereby irrevocably designate and
appoint the Company and its duly authorized officers and agents as my agent and
attorney in fact, to act for and in my behalf and stead to execute and file any
such applications and to do all other lawfully permitted acts to further the
prosecution and issuance of letters patent or copyright registrations thereon
with the same legal force and effect as if executed by me.

(f) Exception to Assignments. I understand that the provisions of this Agreement
requiring assignment of Inventions to the Company do not apply to any invention
which qualifies fully under the provisions of California Labor Code Section 2870
(attached hereto as Exhibit B). I will advise the Company promptly in writing of
any inventions that I believe meet the criteria in California Labor Code
Section 2870 and are not otherwise disclosed on Exhibit A.

4. Conflicting Employment. I agree that, during the term of my employment with
the Company, I will not engage in any other employment, occupation, consulting
or other business activity directly related to the business in which the Company
is now involved or becomes involved during the term of my employment, nor will I
engage in any other activities that conflict with my obligations to the Company.

5. Returning Company Documents. I agree that, at the time of leaving the employ
of the Company, I will deliver to the Company (and will not keep in my
possession, recreate or deliver to anyone else) any and all devices, records,
data, notes, reports, proposals, lists, correspondence, specifications,
drawings, blueprints, sketches, materials, equipment, other documents or
property, or reproductions of any aforementioned items developed by me pursuant
to my employment with the Company or otherwise belonging to the Company, its
successors or assigns. In the event of the termination of my employment, I agree
to sign and deliver the “Termination Certification” attached hereto as
Exhibit C.

6. Notification to New Employer. In the event that I leave the employ of the
Company, I hereby grant consent to notification by the Company to my new
employer about my rights and obligations under this Agreement.

7. Solicitation of Employees. I agree that for a period of twelve (12) months
immediately following the termination of my relationship with the Company for
any reason, whether with or without cause, I shall not either directly or
indirectly solicit, induce, recruit or encourage any

 

Employee’s Initial:

--------------------------------------------------------------------------------

of the Company’s employees to leave their employment, or take away such
employees, or attempt to solicit, induce, recruit, encourage or take away
employees of the Company, either for myself or for any other person or entity.

8. Conflict of Interest Guidelines. I agree to diligently adhere to the Conflict
of Interest Guidelines attached as Exhibit D hereto.

9. Representations. I agree to execute any proper oath or verify any proper
document required to carry out the terms of this Agreement. I represent that my
performance of all the terms of this Agreement will not breach any agreement to
keep in confidence proprietary information acquired by me in confidence or in
trust prior to my employment by the Company. I have not entered into, and I
agree I will not enter into, any oral or written agreement in conflict herewith.

10. Arbitration and Equitable Relief.

(a) Except as provided in Section 10(f) below, I agree that any dispute or
controversy arising out of, relating to, or in connection with this Agreement,
or the interpretation, validity, construction, performance, breach, or
termination thereof, shall be settled by binding arbitration to be held in Santa
Clara County, California in accordance with the National Rules for the
Resolution of Employment Disputes then in effect of the American Arbitration
Association (the “Rules”). The arbitrator may grant injunctions or other relief
in such dispute or controversy. The decision of the arbitrator shall be final,
conclusive and binding on the parties to the arbitration. Judgment may be
entered on the arbitrator’s decision in any court having jurisdiction.

(b) The arbitrator shall apply California law to the merits of any dispute or
claim, without reference to rules of conflicts of law. The arbitration
proceedings shall be governed by federal arbitration law and by the Rules,
without reference to state arbitration law. Employee hereby consents to the
personal jurisdiction of the state and federal courts located in California for
any action or proceeding arising from or relating to this Agreement or relating
to any arbitration in which the parties are participants.

(c) The Company and I shall each pay one-half of the costs and expenses of such
arbitration, and each shall separately pay its counsel fees and expenses.

(d) I understand that nothing in this Section 10 modifies my at-will status.
Either I or the Company can terminate the employment relationship at any time,
with or without cause.

(e) I HAVE READ AND UNDERSTAND SECTION 10, WHICH DISCUSSES ARBITRATION. I
UNDERSTAND THAT BY SIGNING THIS AGREEMENT, I AGREE TO SUBMIT ANY CLAIMS ARISING
OUT OF, RELATING TO, OR IN CONNECTION WITH THIS AGREEMENT, OR THE
INTERPRETATION, VALIDITY, CONSTRUCTION, PERFORMANCE, BREACH OR TERMINATION
THEREOF TO BINDING ARBITRATION, AND THAT THIS ARBITRATION CLAUSE CONSTITUTE A
WAIVER OF MY RIGHT TO A JURY TRIAL AND RELATES TO THE RESOLUTION OF ALL DISPUTES
RELATING TO ALL ASPECTS OF THE EMPLOYER/EMPLOYEE RELATIONSHIP, INCLUDING BUT NOT
LIMITED TO, THE FOLLOWING CLAIMS:

(b) Entire Agreement. This Agreement sets forth the entire agreement and
understanding between the Company and me relating to the subject matter herein
and merges all prior discussions between us. No modification for amendment to
this Agreement, nor any waiver of any rights under this agreement, will be
