 AND WHEREAS as of the date hereof, the Employee serves as the Chief Executive Officer and President of ICS;  
  
 AND WHEREAS the Corporation wishes to employ the Employee and the Employee
wishes to be employed by the Corporation on the terms and conditions contained in this employment agreement (this “Agreement”) upon the consummation of the merger contemplated by the Merger Agreement; 
  
 AND WHEREAS the Corporation is only willing to enter into this Agreement on
the basis that the Employee observe the restrictive covenants set out herein which have been negotiated in good faith and which the Employee acknowledges as being reasonable given the nature of the Employee’s expected position with the
Corporation contemplated by this Agreement. 
  
 NOW THEREFORE THIS
AGREEMENT WITNESSES that in consideration of the mutual covenants and agreements in this Agreement, it is agreed by and between the Employee and the Corporation as follows: 
  
 1. EMPLOYMENT 
  
 1.1 Position 
  
 As of the Effective Time, as such term is defined below, the Corporation shall employ the Employee, and the Employee shall agree to be employed by the
Corporation, as the Corporation’s Chairman of the Board of Directors, on the terms and subject to the conditions herein contained. In this position, Employee shall serve in both the capacity as Chairman of the Board and as an executive officer
of the Corporation. For the first year of employment with the Corporation, measured from the Effective Time, Employee’s primary responsibilities shall be to manage the successful transition and integration of ICS’s business and operations
with the business and operations of the Corporation. 

 1.2 Duties 
  
 During the term of this Agreement, the Employee shall: 
  
 (i) devote the whole of the Employee’s time, skills, experience and attention during normal business hours to the business of the Corporation, and
ensure that the Employee is not at any time engaged in conduct that would interfere with the performance by the Employee of the Employee’s duties under this Agreement or which would constitute a conflict with the interests of the Corporation.
Nothing herein shall be deemed to prevent or inhibit the Employee from making investments in other business enterprises provided the role of the Employee in each such case is passive and does not involve any active involvement in such enterprise.
During the Term of Employment, the Employee will not be employed or engaged in any other business without the prior written permission of the Corporation, which permission will not be unreasonably withheld; 
  
 (ii) well and faithfully serve the Corporation and carry out those
responsibilities as are necessary to perform the functions associated with the Employee’s position; and 
  
 (iii) use the Employee’s best efforts while performing Employee’s responsibilities to promote the success of the business of the Corporation and
act at all times in the best interest of the Corporation. 
  
 2. TERM

  
 This Agreement and the Employee’s employment
hereunder shall become effective and shall commence on the closing of the merger contemplated by the Merger Agreement (the “Effective Time”) and shall continue until the two (2) year anniversary of such commencement date (the “Term of
Employment”). Following the Term of Employment, this Agreement shall be terminated and have no further force or effect, except with regard to Section 4 and Section 5, as stated below. The Corporation and the Employee understand and agree that
Employee may still be an “at-will” employee of the Corporation after the termination of this Agreement. 
  
 3. REMUNERATION 
  
 3.1 Compensation 
  
 The Corporation shall pay to the Employee as compensation for the performance of the Employee’s duties herein a salary at the rate of $325,000 per annum (the “Base Salary”), payable in accordance with the Corporation’s
normal payroll procedures and subject to Section 6.14. The Employee agrees that such salary shall be reviewed annually during the normal course of the Corporation’s focal review process or may be otherwise increased from time to time by the
Corporation, and such revised annual salary shall be referred to hereinafter as the “Base Salary.” The Employee further agrees that at such time as Employee is primarily providing services in his capacity as Chairman of the Board (no
longer providing day-to-day services as an executive officer of the Corporation), Employee’s compensation shall be adjusted hereunder and Employee will thereafter be compensated in accordance with the then-existing compensation structure for
non-employee directors. 
  

 2 

 The Employee will also be eligible to participate in the Corporation’s Incentive Compensation Plan
which provides for certain cash incentive compensation upon the achievement of certain individual, unit and Corporation-wide performance goals. The Employee’s individual incentive target under the Incentive Compensation Plan shall be equal to
seventy-five percent (75%) of the Base Salary. 
  
 The Employee
will also be eligible to participate in all of the Corporation’s other incentive compensation plans for which employees of the Corporation or its subsidiaries of similar seniority participate. 
  
 3.2 Stock Options 
  
 The Employee shall be eligible to be granted nonqualified options to
purchase shares of Corporation’s common stock or other equity compensation generally paid to the employees of the Corporation (collectively, the “Equity Awards”), including the follow specific Equity Awards: 
  
 (1) the Employee will be eligible to receive, under the
Merger Agreement, two stock option grants to purchase shares of the Corporation’s common stock for each option to purchase ICS common stock which had previously been granted to the Employee (the “Replacement Option Grants.”) One of
the Replacement Option Grants shall be for the same number of shares and shall be vested to the same extent as the ICS option which this option is intended to replace and shall have the same term as set forth in Corporation’s standard form of
stock option agreement (the “First Replacement Option Grant”). The second of the Replacement Option Grants shall be for a number of shares which is calculated by multiplying the number of shares subject to the ICS option for which this
option is intended as a replacement by the Implied All Stock Exchange Ratio under the Merger Agreement, and then subtracting the number of shares subject to the First Replacement Option Grant, shall vest according to the vesting schedule and shall
have the same term as set forth in the Corporation’s standard form of stock option agreement (the “Second Replacement Option Grant”); and 
  
 (2) the Employee shall also be eligible to receive an option grant of 200,000 shares that will vest with regard to 50% of such option
shares on Employee’s first anniversary of employment and with regard to the remaining 50% of such option shares on Employee’s second anniversary of employment with Corporation, provided Employee continues to remain an employee of the
Corporation through such dates. 
  
 Any Equity Awards shall be granted subject to
approval of the board of directors of the Corporation (or the compensation committee thereof). Any Equity Awards shall be granted pursuant and be subject to the terms of the Corporation’s stock option and/or equity incentive plans and customary
form of agreements, and, except as otherwise described herein, shall vest and become exercisable in accordance with the vesting and exercisability schedule generally applicable to stock options granted to similarly situated employees.

 3.3 Benefits 
  
 The Employee shall be entitled to participate in all of the benefit plans for employees of the Corporation in effect from time to time, in accordance with
the terms of the formal plan documents, including medical, dental, group life and disability plans, as of and with effect from the Effective Date. Employee’s years of service with ICS prior to the Effective Time shall be counted as years of
service with the Corporation for purposes of eligibility and vesting (other than vesting with respect to any equity-based compensation). The Corporation reserves the right to unilaterally revise the terms of the benefit plans of general application
to all employees or to eliminate any such benefit plan altogether. 
  
 3.4
Vacation 
  
 The Employee will be entitled to four (4)
weeks paid vacation per year in accordance with the Corporation’s generally established policies. The Employee shall endeavor to schedule such vacation to be taken so as to not unreasonably interfere with the demands of the business of the
Corporation after taking into account the personal plans of the Employee. 
  
 3.5 Expenses 
  
 The Corporation shall
reimburse the Employee for all out-of-pocket expenses and other disbursements actually and properly incurred by the Employee in connection with the Employee’s duties hereunder or otherwise properly incurred by the Employee for and on behalf of

any Development made, conceived, learned or reduced to practice during the course of the Employee’s employment, whether past, present or future, and all trade secret, patent, copyright, mask work and other intellectual property rights
world-wide therein or otherwise related thereto whether known or otherwise learned, are the property of the Corporation, and all of the Employee’s right, title and interest in and to the same are hereby assigned (and shall hereby be assigned
when first reduced to practice or first fixed in a tangible medium, as applicable) to the Corporation, whether or not they are capable of statutory protection and whether or not they are made by the Employee or jointly with other persons. The
Employee also agrees to assign all of the Employee’s right, title and interest in and to any particular Development to a third party, including the United States, solely as directed by the 

  

 7 

 
Corporation. “Developments” means all discoveries, know-how, inventions, designs, works of authorship, ideas, methods, uses, business methods,
contributions, developments, algorithms, processes, compositions, techniques and any improvements thereof (whether or not patentable or copyrightable), legally recognized proprietary rights, and any other intellectual property rights (including
patents, copyrights, mask works, trademarks, topographies, know-how and trade secrets), and all records and copies of records, relating to the foregoing. The Employee also hereby waives all moral rights into any copyright assigned hereunder. During
the period of the Employee’s employment and for six (6) months after termination of the Employee’s employment with the Corporation, the Employee will promptly disclose to the Corporation fully and in writing all Developments made,
conceived, learned or reduced to practice by the Employee, either alone or jointly with others. In addition, the Employee will promptly disclose to the Corporation all patent applications filed by the Employee or on the Employee’s behalf within
one (1) year after termination of employment. At the time of each such disclosure, the Employee will advise the Corporation in writing of any Developments related thereto that Employee believes to fully qualify for protection under Section 2870; and
the Employee will at that time provide to the Corporation in writing all evidence necessary to substantiate that belief. The Corporation will keep in confidence and will not use for any purpose or disclose to third parties without the
Employee’s consent any confidential information disclosed in writing to the Corporation pursuant to this Agreement relating to the identified Developments that qualify fully for protection under the provisions of Section 2870, as defined below.
The Employee will preserve the confidentiality of any Development that does not fully qualify for protection under Section 2870. The Employee will maintain accurate records of (including in the form of notes, sketches, drawings and in any other form
that may be required by the Corporation), which records shall be available to and remain the sole property of the Corporation at all times, and will promptly and fully disclose and confirm the assignment in writing to the Corporation (or to a third
party designated by the Corporation) of, all such Developments including all intellectual property rights therein. 
  
 (2) The Employee shall assist the Corporation and execute, verify and deliver such documents and do everything necessary or desirable (including appearing
as a witness) to apply for, obtain, perfect, evidence, sustain or enforce patents, copyrights, mask works, industrial designs or other legal protection including other intellectual property rights for such Developments in all countries including any
continuation, division, re-issue or renewal thereof. The Employee’s obligation to assist the Corporation with respect to such Developments shall continue beyond the termination of Employee’s employment. In the event the Corporation
requires more than nominal assistance from the Employee following Employee’s termination, the Corporation shall reasonably compensate the Employee for Employee’s time. In the event the Corporation is unable for any reason, after reasonable
effort, to secure the Employee’s signature on any document needed in connection with the above-mentioned actions, the Employee hereby irrevocably designates and appoints the Corporation and its duly authorized officers and agents as the
Employee’s agent and attorney in fact, which appointment is coupled with an interest to act for and on the Employee’s behalf to execute, verify and file any such documents and to do all other lawfully permitted acts to further the purposes
of this Agreement with the same legal force and effect as if executed by the Employee. The Employee hereby waives any and all claims, of any nature whatsoever, which the Employee now or may hereafter have for infringement of any proprietary rights
or intellectual property rights assigned hereunder to the Corporation. 
  

 8 

 (3) The memorandum sheet attached as Schedule A fully describes all Developments developed by Employee or
jointly with others before being employed by ICS and which are excluded from the scope of this Agreement (“Prior Inventions”). If disclosures of such Prior Invention is restricted by a prior confidentiality agreement, the Employee will
only disclose a cursory name for such Prior Invention, the identity of its owner and the fact of the confidentiality obligation. If no such disclosure is attached, the Employee represents that there are no Prior Inventions. If, in the course of
Employee’s employment with the Corporation, Employee incorporates a Prior Invention into any Development, then the Corporation is hereby granted and shall have a nonexclusive, royalty-free, irrevocable, perpetual, worldwide license (with rights
to sublicense through multiple tiers of sublicensees) to make, have made, modify, use and sell such Prior Invention. Notwithstanding the foregoing, the Employee agrees that the Employee will not incorporate, or permit to be incorporated, Prior
Inventions in any Development without the Corporation’s prior written consent. 
  
 (4) This Agreement does not apply to a Development which qualifies fully as a nonassignable Development under Section 2870 of the California Labor Code (“Section 2870”). Employee certifies the Employee has
reviewed the notification on Exhibit B (Limited Exclusion Notification) and agrees that the Employee’s signature acknowledges receipt of the notification. 
  

(5) The Employee acknowledges that all original works of authorship which are made by the Employee (solely or jointly with others) within the scope of
the Employee’s employment and which are protectable by copyright are “works made for hire,” pursuant to United States Copyright Act (17 U.S.C., Section 101). 
  
 5.3 Non-Competition and Non-Solicitation 
  
 (1) The Employee acknowledges that in the Employee’s position of Chairman of the Board of Directors, the Employee
occupies a position of trust and confidence. The Employee understands that the following restrictions may limit the Employee’s ability to earn a livelihood in a business which, directly or indirectly, compete with Corporation. However, the
Employee agrees that the Employee will receive sufficient consideration and other benefits as an Employee of Corporation to clearly justify such restrictions which, in any event, given the Employee’s skills and ability will not prevent the
Employee from earning a living. The Employee acknowledges that all restrictions contained in Section 5.3 are reasonable and valid for the adequate protection of the legitimate business interests and goodwill of the Corporation and are no broader
than is necessary to protect such interests and goodwill. 
  
 (2)
The Employee shall not (without the prior written consent of the Corporation) while employed by Corporation and for twelve (12) months after the termination of the Employee’s employment, for any reason, provided such termination occurs during

capacity whatsoever carry on, or be engaged in, or have any financial or other interest in or be otherwise commercially involved in any endeavor, activity or business or which is in whole or in part competitive with any of the businesses carried on
by the Corporation within the respective territories in which such businesses are then carried on (except 

  

 9 

 
for any equity share investment in a public company whose shares are listed on a recognized stock exchange where such share investment does not in the
aggregate exceed 5% of the issued equity shares of such company). 
  
 (3) The Employee shall not (without the prior written consent of the Corporation) while employed by Corporation and for twelve (12) months after the termination of the Employee’s employment, for any reason, provided such termination

any other capacity whatsoever:

attempt to solicit any customer or prospective customer for the purpose of (i) persuading or attempting to persuade any such customer to cease doing business or to curtail the business which such customer or prospective customer has customarily
conducted or contemplating conducting with the Corporation (including any subsidiary, including but not limited to ICS, or any affiliated corporation), whether or not the relationship between the Corporation and such customer or prospective customer
was originally established in whole or in part through the efforts of the Employee; or (ii) to solicit the business of such customer or prospective customer in respect to any products or services which are competitive with the Corporation (including
any subsidiary, including but not limited to ICS, or any affiliated corporation); or. 
  
 (b) solicit or attempt to solicit or assist any individual or entity to solicit the employment or engagement of or otherwise entice away
from the employment of the Corporation (including any subsidiary, including but not limited to ICS, or any affiliated corporation) any employee of the Corporation (including any subsidiary, including but not limited to ICS, or any affiliated
corporation). 
  
 (4) The parties hereto agree that any breach by
the Employee of this Section 5.3 shall be deemed to cause the Corporation irreparable harm which cannot adequately be compensated for in damages and that the Corporation in addition to all other remedies, shall be entitled to injunctive or other
equitable relief to restrain such breach. 
  
 5.4 Cumulative Rights

  
 The various rights and remedies of the Corporation
hereunder are cumulative and non-exclusive of one another. The use of or resort to any one such right or remedy shall not preclude or limit the exercise of any other right or remedy by the Corporation. The provisions of this Agreement shall not in
any way limit or abridge the rights of the Corporation in the obligations of the Employee at common law or under statue, including but not limited to the laws of unfair competition, copyright, trade secrets, and trade-mark, all of which shall be in
addition to the Corporation’s rights and the Employee’s obligations under this Agreement. The Employee acknowledges that the Employee is a fiduciary of the Corporation.

 EMPLOYMENT AGREEMENT 
  
 THIS EMPLOYMENT AGREEMENT dated as of the 15th day of June, 2005, is entered into by and between Dinh Bui (the “Employee”) and Integrated Device
Technology, Inc, a Delaware corporation (“the Corporation”). 
  
 RECITALS 
  
 WHEREAS Integrated Circuit Systems,
Inc. (“ICS”), the Corporation and one of its subsidiaries (“Merger Sub”) anticipate entering into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, on the terms and subject to the conditions
set forth therein, Merger Sub will merge with ICS and the resulting entity will become a wholly-owned subsidiary of the Corporation; 
  
 AND WHEREAS as of the date hereof, the Employee serves as the Vice President of FTG of ICS; 
  
 AND WHEREAS the Corporation wishes to employ the Employee and the Employee wishes to be employed by the Corporation on the
terms and conditions contained in this employment agreement (this “Agreement”) upon the consummation of the merger contemplated by the Merger Agreement; 
  
 AND WHEREAS the Corporation is only willing to enter into this Agreement on the basis that the Employee observe the
restrictive covenants set out herein which have been negotiated in good faith and which the Employee acknowledges as being reasonable given the nature of the Employee’s expected position with the Corporation contemplated by this Agreement.

  
 NOW THEREFORE THIS AGREEMENT WITNESSES that in consideration
of the mutual covenants and agreements in this Agreement, it is agreed by and between the Employee and the Corporation as follows: 
  
 1. EMPLOYMENT 
  
 1.1 Position 
  
 As
of the Effective Time, as such term is defined below, the Corporation shall employ the Employee, and the Employee shall agree to be employed by the Corporation, as the Corporation’s Vice President of FTG, on the terms and subject to the
conditions herein contained. 

 1.2 Duties 
  
 During the term of this Agreement, the Employee shall: 
  
 (i) devote the whole of the Employee’s time, skills, experience and attention during normal business hours to the business of the Corporation, and
ensure that the Employee is not at any time engaged in conduct that would interfere with the performance by the Employee of the Employee’s duties under this Agreement or which would constitute a conflict with the interests of the Corporation.
Nothing herein shall be deemed to prevent or inhibit the Employee from making investments in other business enterprises provided the role of the Employee in each such case is passive and does not involve any active involvement in such enterprise.
During the Term of Employment, the Employee will not be employed or engaged in any other business without the prior written permission of the Corporation, which permission will not be unreasonably withheld; 
  
 (ii) well and faithfully serve the Corporation and carry out those
responsibilities as are necessary to perform the functions associated with the Employee’s position; and 
  
 (iii) use the Employee’s best efforts while performing Employee’s responsibilities to promote the success of the business of the Corporation and
act at all times in the best interest of the Corporation. 
  
 2. TERM

  
 This Agreement and the Employee’s employment
hereunder shall become effective and shall commence on the closing of the merger contemplated by the Merger Agreement (the “Effective Time”) and shall continue until the two (2) year anniversary of such commencement date (the “Term of
Employment”). Following the Term of Employment, this Agreement shall be terminated and have no further force or effect, except with regard to Section 4 and Section 5, as stated below. The Corporation and the Employee understand and agree that
Employee may still be an “at-will” employee of the Corporation after the termination of this Agreement. 
  
 3. REMUNERATION 
  
 3.1 Compensation 
  
 The Corporation shall pay to the Employee as compensation for the performance of the Employee’s duties herein a salary at the rate of $251,538 per annum (the “Base Salary”), payable in accordance with the Corporation’s
normal payroll procedures and subject to Section 6.14. The Employee agrees that such salary shall be reviewed annually during the normal course of the Corporation’s focal review process or may be otherwise increased from time to time by the
Corporation, and such revised annual salary shall be referred to hereinafter as the “Base Salary.” 
  
 The Employee will also be eligible to participate in the Corporation’s Incentive Compensation Plan which provides for certain cash incentive
compensation upon the achievement of certain individual, unit and Corporation-wide performance goals. The Employee’s individual incentive target under the Incentive Compensation Plan shall be equal to thirty percent (30%) of the Base Salary.

  

 2 

 The Employee will also be eligible to participate in all of the Corporation’s other incentive
compensation plans for which employees of the Corporation or its subsidiaries of similar seniority participate. 
  
 3.2 Stock Options 
  
 The Employee shall be eligible to be granted nonqualified options to purchase shares of Corporation’s common stock or other equity compensation
generally paid to the employees of the Corporation (collectively, the “Equity Awards”), including the follow specific Equity Awards: 
  
 (1) the Employee will be eligible to receive, under the Merger Agreement, two stock option grants to purchase shares of the
Corporation’s common stock for each option to purchase ICS common stock which had previously been granted to the Employee (the “Replacement Option Grants.”) One of the Replacement Option Grants shall be for the same number of shares
and shall be vested to the same extent as the ICS option which this option is intended to replace and shall have the same term as set forth in Corporation’s standard form of stock option agreement (the “First Replacement Option
Grant”). The second of the Replacement Option Grants shall be for a number of shares which is calculated by multiplying the number of shares subject to the ICS option for which this option is intended as a replacement by the Implied All Stock
Exchange Ratio under the Merger Agreement, and then subtracting the number of shares subject to the First Replacement Option Grant, shall vest according to the vesting schedule and shall have the same term as set forth in the Corporation’s
standard form of stock option agreement (the “Second Replacement Option Grant”); and 
  
 (2) the Employee shall also be eligible to receive an option grant of 100,000 shares that will vest with regard to 33,333 of such option
shares on Employee’s second anniversary of employment, 33,333 of such option shares on Employee’s third anniversary of employment and the remaining 33,334 of such option shares on Employee’s fourth anniversary of employment with
Corporation, provided Employee continues to remain an employee of the Corporation through such dates. 
  
 Any Equity Awards shall be granted subject to approval of the board of directors of the Corporation (or the compensation committee thereof). Any Equity Awards shall be granted pursuant and be subject to the terms of
the Corporation’s stock option and/or equity incentive plans and customary form of agreements, and, except as otherwise described herein, shall vest and become exercisable in accordance with the vesting and exercisability schedule generally
applicable to stock options granted to similarly situated employees. 
  
 3.3
Benefits 
  
 The Employee shall be entitled to
participate in all of the benefit plans for employees of the Corporation in effect from time to time, in accordance with the terms of the formal plan documents, including medical, dental, group life and disability plans, as of and with effect from

general application to all employees or to eliminate any such benefit plan altogether. 
  
 3.4 Vacation 
  
 The Employee will be
entitled to four (4) weeks paid vacation per year in accordance with the Corporation’s generally established policies. The Employee shall endeavor to schedule such vacation to be taken so as to not unreasonably interfere with the demands of the
business of the Corporation after taking into account the personal plans of the Employee. 
  
 3.5 Expenses 
  
 The Corporation shall reimburse the Employee for all out-of-pocket expenses and other disbursements actually and properly incurred by the Employee in connection with the Employee’s duties hereunder or otherwise properly incurred by the

responsibilities where such conduct has not been cured after forty-five (45) days written notice from the Employee; 
  
 (2) a reduction by the Corporation in the Employee’s Base Salary unless such reduction is part of a Corporation wide reduction in compensation to

 5. COVENANTS OF EMPLOYEE 
  

5.1 Confidentiality 
  
 Except as may be required by applicable law or the rules and regulations of any national securities exchange or national automated quotation system, the
Employee shall not, at any time or under any circumstances during the term of the Employee’s employment with the Corporation and after the termination of the Employee’s employment, except for the benefit of the Corporation in carrying out
the Employee’s duties hereunder, directly or indirectly communicate or disclose to any person any confidential knowledge or information of the Corporation or any of its subsidiaries howsoever acquired (except as set forth below), nor shall the
Employee utilize or make available any such knowledge or information directly or indirectly in connection with any business or activity in which the Employee is or proposes to be involved, or in connection with the transfer or proposed transfer of
any of the Employee’s securities or in connection with the solicitation or acceptance of employment with any person. Knowledge and information subject to this Section 5.1 includes, but is not limited to, formulas, circuits, drawings, designs,
mask works, plans, proposals, marketing and sales data, financial information, cost and pricing information, customer lists, trade secrets, personnel information, policies and procedures, organizational charts, telephone directories, and concepts
and ideas related to the past, present, or future business of the Corporation or any affiliated entity (including parents and subsidiaries, including but not limited to ICS) which have not been publicly released by duly authorized representatives of
Corporation. The Employee will be under no obligation of confidentiality with respect to any information that the Employee can show (i) is or becomes available to the general public through no fault of the Employee; (ii) was known to the Employee
before disclosure without obligation of confidentiality; (iii) is independently developed by the Employee; or (iv) is lawfully received from a third party without obligation of confidentiality. 
  
 The terms of this Section 5.1 shall survive the termination of this
Agreement. 
  
 5.2 Intellectual Property Rights 
  
 (1) Subject to Section 5.2(4), any Development made, conceived,
learned or reduced to practice during the course of the Employee’s employment, whether past, present or future, and all trade secret, patent, copyright, mask work and other intellectual property rights world-wide therein or otherwise related
thereto whether known or otherwise learned, are the property of the Corporation, and all of the Employee’s right, title and interest in and to the same are hereby assigned (and shall hereby be assigned when first reduced to practice or first
fixed in a tangible medium, as applicable) to the Corporation, whether or not they are capable of statutory protection and whether or not they are made by the Employee or jointly with other persons. The Employee also agrees to assign all of the
Employee’s right, title and interest in and to any particular Development to a third party, including the United States, solely as directed by the Corporation. “Developments” means all discoveries, know-how, inventions, designs, works
of authorship, ideas, methods, uses, business methods, contributions, developments, algorithms, processes, compositions, techniques and any improvements thereof (whether or not patentable or copyrightable), legally recognized proprietary rights, and
any other intellectual property rights (including patents, copyrights, mask works, trademarks, topographies, know-how and trade secrets), and all records and copies of records, relating to the foregoing. The Employee also 

  

 7 

 
hereby waives all moral rights into any copyright assigned hereunder. During the period of the Employee’s employment and for six (6) months after
termination of the Employee’s employment with the Corporation, the Employee will promptly disclose to the Corporation fully and in writing all Developments made, conceived, learned or reduced to practice by the Employee, either alone or jointly
with others. In addition, the Employee will promptly disclose to the Corporation all patent applications filed by the Employee or on the Employee’s behalf within one (1) year after termination of employment. At the time of each such disclosure,
the Employee will advise the Corporation in writing of any Developments related thereto that Employee believes to fully qualify for protection under Section 2870; and the Employee will at that time provide to the Corporation in writing all evidence
necessary to substantiate that belief. The Corporation will keep in confidence and will not use for any purpose or disclose to third parties without the Employee’s consent any confidential information disclosed in writing to the Corporation
pursuant to this Agreement relating to the identified Developments that qualify fully for protection under the provisions of Section 2870, as defined below. The Employee will preserve the confidentiality of any Development that does not fully
qualify for protection under Section 2870. The Employee will maintain accurate records of (including in the form of notes, sketches, drawings and in any other form that may be required by the Corporation), which records shall be available to and
remain the sole property of the Corporation at all times, and will promptly and fully disclose and confirm the assignment in writing to the Corporation (or to a third party designated by the Corporation) of, all such Developments including all
intellectual property rights therein. 
  
 (2) The Employee shall
assist the Corporation and execute, verify and deliver such documents and do everything necessary or desirable (including appearing as a witness) to apply for, obtain, perfect, evidence, sustain or enforce patents, copyrights, mask works, industrial
designs or other legal protection including other intellectual property rights for such Developments in all countries including any continuation, division, re-issue or renewal thereof. The Employee’s obligation to assist the Corporation with
respect to such Developments shall continue beyond the termination of Employee’s employment. In the event the Corporation requires more than nominal assistance from the Employee following Employee’s termination, the Corporation shall
reasonably compensate the Employee for Employee’s time. In the event the Corporation is unable for any reason, after reasonable effort, to secure the Employee’s signature on any document needed in connection with the above-mentioned
actions, the Employee hereby irrevocably designates and appoints the Corporation and its duly authorized officers and agents as the Employee’s agent and attorney in fact, which appointment is coupled with an interest to act for and on the
Employee’s behalf to execute, verify and file any such documents and to do all other lawfully permitted acts to further the purposes of this Agreement with the same legal force and effect as if executed by the Employee. The Employee hereby
waives any and all claims, of any nature whatsoever, which the Employee now or may hereafter have for infringement of any proprietary rights or intellectual property rights assigned hereunder to the Corporation. 
  
 (3) The memorandum sheet attached as Schedule A fully describes all
Developments developed by Employee or jointly with others before being employed by ICS and which are excluded from the scope of this Agreement (“Prior Inventions”). If disclosures of such Prior Invention is restricted by a prior
confidentiality agreement, the Employee will only disclose a cursory name for such Prior Invention, the identity of its owner and the fact of the confidentiality obligation. If no such disclosure is attached, the Employee represents that there are
no Prior 

  

 8 

 
Inventions. If, in the course of Employee’s employment with the Corporation, Employee incorporates a Prior Invention into any Development, then the
Corporation is hereby granted and shall have a nonexclusive, royalty-free, irrevocable, perpetual, worldwide license (with rights to sublicense through multiple tiers of sublicensees) to make, have made, modify, use and sell such Prior Invention.
Notwithstanding the foregoing, the Employee agrees that the Employee will not incorporate, or permit to be incorporated, Prior Inventions in any Development without the Corporation’s prior written consent. 
  
 (4) This Agreement does not apply to a Development which qualifies fully as a
nonassignable Development under Section 2870 of the California Labor Code (“Section 2870”). Employee certifies the Employee has reviewed the notification on Exhibit B (Limited Exclusion Notification) and agrees that the Employee’s
signature acknowledges receipt of the notification. 
  
 (5) The
Employee acknowledges that all original works of authorship which are made by the Employee (solely or jointly with others) within the scope of the Employee’s employment and which are protectable by copyright are “works made for hire,”
pursuant to United States Copyright Act (17 U.S.C., Section 101). 
  
 5.3
Non-Competition and Non-Solicitation 
  
 (1) The
Employee acknowledges that in the Employee’s position of Vice President of FTG, the Employee occupies a position of trust and confidence. The Employee understands that the following restrictions may limit the Employee’s ability to earn a
livelihood in a business which, directly or indirectly, compete with Corporation. However, the Employee agrees that the Employee will receive sufficient consideration and other benefits as an Employee of Corporation to clearly justify such
restrictions which, in any event, given the Employee’s skills and ability will not prevent the Employee from earning a living. The Employee acknowledges that all restrictions contained in Section 5.3 are reasonable and valid for the adequate
protection of the legitimate business interests and goodwill of the Corporation and are no broader than is necessary to protect such interests and goodwill. 
  
 (2) The Employee shall not (without the prior written consent of the Corporation) while employed by Corporation and for twelve (12) months after the
termination of the Employee’s employment, for any reason, provided such termination occurs during the Term of Employment, whether directly or indirectly, either alone or in conjunction with any individual, firm, corporation, association or
other entity (except for the Corporation), whether as principal, agent, stockholder or in any other capacity whatsoever carry on, or be engaged in, or have any financial or other interest in or be otherwise commercially involved in any endeavor,
activity or business or which is in whole or in part competitive with any of the businesses carried on by the Corporation within the respective territories in which such businesses are then carried on (except for any equity share investment in a
public company whose shares are listed on a recognized stock exchange where such share investment does not in the aggregate exceed 5% of the issued equity shares of such company). 
  
 (3) The Employee shall not (without the prior written consent of the Corporation) while employed by Corporation and for
twelve (12) months after the termination of the Employee’s employment, for any reason, provided such termination occurs during the Term of

Employment, whether directly or indirectly, either alone or in conjunction with any individual, firm, corporation, association or other entity (except for
the Corporation), whether as a principal, agent, stockholder or in any other capacity whatsoever: 
  
 (a) solicit or attempt to solicit any customer or prospective customer for the purpose of (i) persuading or attempting to persuade any
such customer to cease doing business or to curtail the business which such customer or prospective customer has customarily conducted or contemplating conducting with the Corporation (including any subsidiary, including but not limited to ICS, or
any affiliated corporation), whether or not the relationship between the Corporation and such customer or prospective customer was originally established in whole or in part through the efforts of the Employee; or (ii) to solicit the business of
such customer or prospective customer in respect to any products or services which are competitive with the Corporation (including any subsidiary, including but not limited to ICS, or any affiliated corporation); or. 
  
 (b) solicit or attempt to solicit or assist any individual
or entity to solicit the employment or engagement of or otherwise entice away from the employment of the Corporation (including any subsidiary, including but not limited to ICS, or any affiliated corporation) any employee of the Corporation
(including any subsidiary, including but not limited to ICS, or any affiliated corporation). 
  
 (4) The parties hereto agree that any breach by the Employee of this Section 5.3 shall be deemed to cause the Corporation irreparable harm which cannot adequately be compensated for in damages and that the Corporation
in addition to all other remedies, shall be entitled to injunctive or other equitable relief to restrain such breach. 
  
 5.4 Cumulative Rights 
  
 The various rights and remedies of the Corporation hereunder are cumulative and non-exclusive of one another. The use of or resort to any one such right
or remedy shall not preclude or limit the exercise of any other right or remedy by the Corporation. The provisions of this Agreement shall not in any way limit or abridge the rights of the Corporation in the obligations of the Employee at common law
or under statue, including but not limited to the laws of unfair competition, copyright, trade secrets, and trade-mark, all of which shall be in addition to the Corporation’s rights and the Employee’s obligations under this Agreement. The
Employee acknowledges that the Employee is a fiduciary of the Corporation.
