INFORMATION REGARDING THE ANNUAL GENERAL MEETING

General

This proxy statement (“Proxy Statement”) has information about the 2018 Annual General Meeting of Shareholders (the “Annual Meeting”) and was prepared by our management for the Board of Directors of Alpha and Omega Semiconductor Limited, an exempted limited liability company organized under the laws of Bermuda (the "Company"). The Notices of the Annual Meeting and the Proxy Statement are being mailed to our shareholders on or about October 9, 2018. Our Board of Directors supports each proposal as described in this Proxy Statement for which your vote is solicited.

Our Board of Directors asks you to appoint Dr. Mike F.

If appointed by you, your shares represented by a properly completed proxy received by us will be voted at the Annual Meeting in the manner specified in the proxy card or, if no instructions are marked on the proxy, your shares will be voted as described below. Although management does not know of any other matter to be acted upon at the Annual Meeting, unless contrary instructions are given, shares represented by valid proxies will be voted by the persons named on the accompanying proxy card in the manner the proxy holders deem appropriate for any other matters that may properly come before the Annual Meeting.

QUESTIONS AND ANSWERS RELATING TO THE ANNUAL GENERAL MEETING

Why did I receive these materials?

Only our shareholders as of the close of business on September 28, 2018, which we refer to as the “Record Date,” are entitled to vote at the Annual Meeting, which will be held at 8:00 a.m., Friday on November 9, 2018 Taiwan local time (at 4:00 p.m. on November 8, 2018 U.S. Pacific Standard Time) at the Grand Victoria Hotel located at 168, Jingye 4th Road, Zhongshan District, Taipei, Taiwan. As a shareholder, you are invited to attend the Annual Meeting and are requested to vote on the items of business described in the Proxy Statement.  We distribute the Proxy Statement and related materials to our shareholders of record on the Record Date.

The Proxy Statement provides notice of the Annual Meeting, describes the proposals presented for shareholder actions and includes information about the proposals, information concerning our management, corporate governance, principal shareholders and other relevant information.  The accompanying proxy card also enables shareholders to vote on the matters without having to attend the Annual Meeting in person.

What is a proxy?

A proxy is your legal designation of another person to vote on your behalf. By completing and returning the enclosed proxy card, you are providing each of our Chief Executive Officer and the Chief Financial Officer with the authority to vote your shares in the manner you indicate on your proxy card.

What are the proposals to be considered at the Annual Meeting and what vote is required to approve each proposal?

The Board of Directors is submitting the following five (5) proposals for shareholder actions at the Annual Meeting:

• Proposal 1 - the election of seven (7) nominees to serve as directors on our Board of Directors until the next annual general meeting of shareholders or until their successors are duly elected and qualified. The affirmative vote of a plurality of the votes cast at the Annual Meeting is required for the election of directors. “Plurality” means that the individuals who receive the highest number of votes are elected as directors, up to the number of directors to be chosen at the meeting. A properly executed proxy marked “withhold authority” with respect to the election of one or more directors will not be voted with respect to the director or directors indicated, although it will be counted for purposes of determining whether there is a quorum. Broker non-votes will have no effect on the outcome of the election of directors.

• Proposal 2 - the approval, on an advisory basis, the compensation of our named executive officers as described in the Proxy Statement, commonly known as the “say-on-pay” vote. This proposal is deemed to be approved by shareholders if it receives the affirmative vote of holders of a majority of the votes cast in person or represented by proxy and entitled to vote at the Annual Meeting. However, Proposal 2 represents only an advisory vote of shareholders and is not binding on the Company, although our Board of Director will consider results of the vote in setting the compensation of our named executive officers. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

• Proposal 3 - the approval of the adoption of the Company’s 2018 Omnibus Incentive Plan. The affirmative vote of holders of a majority of the votes cast in person or represented by proxy and entitled to vote at the Annual Meeting will be required to approve this proposal. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

• Proposal 4 - the approval of the adoption of our 2018 Employee Share Purchase Plan. The affirmative vote of holders of a majority of the votes cast in person or represented by proxy and entitled to vote at the Annual Meeting will be required to approve this proposal. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

• Proposal 5 -the approval and ratification of the appointment of BDO USA, LLP (“BDO”) as our independent registered public accounting firm, and the authorization for our Board of Directors to determine the remuneration of the accounting firm, for the fiscal year ending June 30, 2019. The affirmative vote of holders of a majority of the votes cast in person or represented by proxy and entitled to vote at the Annual Meeting will be required to approve this proposal. Abstention will have no effect on the outcome of this proposal.

How are votes counted and how will a broker non-vote be treated and counted?

If you are a “street name” holder or beneficial owner, you have the right to direct your broker, bank, trust or other nominee on how to vote your shares at the Annual Meeting. The broker, bank, trust or other nominee that is the shareholder of record for your shares is obligated to provide you with a voting instruction card for you to use for this purpose.  If you hold your shares in a brokerage account but you fail to return your voting instruction card to your broker, your shares may constitute “broker non-votes.” Generally, broker non-votes occur on a matter when a broker is not permitted to vote on that matter without instructions from the beneficial owner and instructions are not given.  If you are a beneficial owner and your broker, bank, trust or other nominee holds your shares in its name, it is not permitted for the broker, bank, trust or other nominees to vote your shares on the election of directors (Proposal 1); the “say-on-pay” vote (“Proposal 2); the approval and adoption of 2018 Omnibus Incentive Plan (Proposal 3); and the approval and adoption of the 2018 Employee Share Purchase Plan (Proposal 4). The broker, bank, trust or other nominees, however, are permitted to vote for the approval and ratification of the appointment of BDO USA, LLP (Proposal 5), therefore we do not expect any broker non-votes for Proposal 5.  Broker non-votes are counted for purposes of establishing a quorum. A properly executed proxy marked “abstain” with respect to Proposals 2, 3 and 4 will not be voted, although they will be counted for purposes of determining whether there is a quorum. The effects of broker non-votes for each proposal is described in more detail in response to the previous question above.

For Proposal 1 with respect to the election of directors, you may vote “FOR” all or some of the nominees or you may vote “WITHHELD” with respect to one or more of the nominees.  You may not cumulate your votes for the election of directors. Broker non-votes do not have any effect on the outcome of the votes.

For Proposal 2 with respect to the “say-on-pay” vote, you may vote “FOR,” “AGAINST” or “ABSTAIN.” Abstentions and broker non-votes will have no effect on the outcome of the votes.

For Proposal 3 with respect to the 2018 Omnibus Incentive Plan, you may vote “FOR,” “AGAINST” or “ABSTAIN.” Abstentions and broker non-votes will have no effect on the outcome of the votes.

For Proposal 4 with respect to the 2018 Employee Share Purchase Plan, you may vote “FOR,” “AGAINST” or “ABSTAIN.” Abstentions and broker non-votes will have no effect on the outcome of the votes.

For Proposal 5 with respect to the appointment and election of BDO USA, LLP as the Company’s independent registered public accounting firm, you may vote “FOR,” “AGAINST” or “ABSTAIN.” Abstentions will have no effect on the outcome of the votes.

Who is entitled to vote at the Annual Meeting?

Only shareholders of record at the close of business on the Record Date are entitled to receive notice of and to participate and vote in the Annual Meeting.  If you were a shareholder of record on the Record Date, you will be entitled to vote all of the shares that you held on that date at the Annual Meeting.

How many votes do I have?

You will be entitled to one vote for each outstanding share of our common shares you own as of the Record Date.  As of the Record Date, there were 23,893,185 shares of our common shares outstanding and eligible to vote at the Annual Meeting.

What is the difference between a “shareholder of record” and a “street name” holder or a “beneficial owner”?

These terms describe how your shares are held.  If your shares are registered directly in your name with Computershare, our transfer agent, you are considered a “shareholder of record.” As the shareholder of record, you have the right to grant your voting proxy directly to our management or to vote in person at the Annual Meeting.  If your shares are held in a brokerage, bank, trust or other nominee, you are considered the beneficial owner of shares held in “street name.” As the beneficial owner, you have the right to direct your broker, bank, trust or nominee how to vote and are also invited to attend the Annual Meeting.

How can I vote my shares at the Annual Meeting?

If you are a shareholder of record, you may vote by mailing a completed proxy card or via the Internet. Instructions for voting via the Internet are described in the proxy card attached to the Proxy Statement. To vote by mailing a proxy card, sign

3

and return the enclosed proxy card in the enclosed prepaid and addressed envelope and your shares will be voted at the Annual Meeting in the manner you directed.  You may also vote in person at the Annual Meeting.

If you are a beneficial owner, your broker, bank, trust or nominee should have provided voting instructions for you to use in directing them how to vote your shares.  You may be eligible to vote your shares over the Internet rather than by mailing a completed voting instruction card provided by the broker, bank, trust or nominee.  Please check the voting instructions card provided by your bank or brokerage house for instructions. You may also vote in person at the Annual Meeting. To do so, you must obtain a legal proxy from the broker, bank, trust or other nominee that holds your shares giving you the right to vote the shares.  Please contact that organization for instructions regarding obtaining a legal proxy.

Can I vote electronically through the Internet?

If you are a shareholder of record, you may vote electronically through the Internet at www.investorvote.com/aosl. The instructions are included in your proxy card.

If your shares are held in “street name,” please check your proxy card or contact your broker, bank, trust or other nominee to determine whether you will be able to vote electronically through the Internet and the deadline for such voting.

Can I change my vote after I return my proxy card?

Yes.  If you are a shareholder of record and submitted your proxy through the mail or Internet, you may revoke your proxy before the vote is taken at the Annual Meeting by any of the following ways:

• granting a proxy through the Internet after the date of your original proxy and before the deadlines for voting included on your proxy card;

• submitting a later-dated proxy by mail before your earlier-dated proxy is voted at the Annual Meeting;

• giving written notice of the revocation of your proxy to our Corporate Secretary at the address shown above that is actually received by our Corporate Secretary prior to the Annual Meeting; or

• voting in person at the Annual Meeting.

If you are a “street name” holder, you may change your vote by submitting new voting instructions to your broker, bank, trust or other nominee or, if you have obtained a legal proxy from your broker, bank, trust or other nominee giving you the right to vote your shares, by attending the Annual Meeting and voting in person. In either case, the powers of the proxy holders will be suspended if you attend the Annual Meeting in person and so request, although attendance at the Annual Meeting will not by itself revoke a previously granted proxy.

How many shares must be present or represented to conduct business at the Annual Meeting?

The presence at the Annual Meeting of at least two shareholders, in person or by proxy and entitled to vote, representing not less than 50% of the aggregate voting power of the Company's common shares issued and outstanding on the Record Date, will constitute a quorum, permitting the conduct of business at the Annual Meeting.

Proxies received but marked as abstentions, votes withheld and broker non-votes (as described below) will be included in the calculation of the number of shares present at the Annual Meeting for quorum purposes.

Who can attend the Annual Meeting?

All shareholders of record as of the close of business on the Record Date may attend the meeting. To attend the Annual Meeting, please follow these instructions:

• If you are a shareholder of record, bring proof of ownership of your shares and a form of identification; or

• If you are a “street name” holder, bring proof of ownership of your shares through your broker, bank, trust or nominee, and a form of identification.  You must have obtained a “legal proxy” from your broker, bank, trust or nominee to vote at the Annual Meeting.

Will shareholders be asked to vote on any other matters?

To the knowledge of the Company and its management, shareholders will vote only on the matters described in the Proxy Statement. However, if any other matters properly come before the Annual Meeting, the persons named as proxies for shareholders will vote on those matters in the manner they consider appropriate.

What should I do if I receive more than one set of voting materials?

You may receive more than one set of voting materials, including multiple copies of the Proxy Statement and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you may receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a shareholder of record and your shares are registered in more than one name, you will receive more than one proxy card.  Please complete, sign, date and return each proxy card and voting instruction card that you receive.

How can I find out the results of the voting at the 2018 Annual Meeting?

Preliminary voting results will be announced at the Annual Meeting.  Final voting results will be disclosed in a Current Report on Form 8-K filed with the Securities and Exchange Commission at the website, www.sec.gov, within four business days after the Annual Meeting.

Who bears the costs of proxy solicitation?

The Company will bear the entire cost of this solicitation of proxies, including the preparation, assembly, printing, and mailing of this proxy statement, the proxy, and any additional solicitation materials that the Company may provide to shareholders. Copies of solicitation materials will be provided to brokerage firms, fiduciaries and custodians holding shares in their names that are beneficially owned by others so that they may forward the solicitation materials to such beneficial owners. The Company will reimburse the brokerage firms, fiduciaries and custodians holding shares in their names for reasonable expenses incurred by them in sending solicitation materials to its beneficial shareholders. The solicitation of proxies will be made by various methods, including by mail, electronic mail, telephone, facsimile, or personally by directors, officers and employees of the Company who will receive no extra compensation for such services.

BOARD OF DIRECTORS AND COMMITTEES OF THE BOARD

Board of Directors

Our Bye-laws provide that our Board of Directors shall consist of not less than two directors. Our Board of Directors currently consists of seven directors. Our Board of Directors is the decision-making body responsible for, among other things, determining policies and guidelines for our business. Our Board of Directors also supervises our executive officers and monitors their implementation of policies and guidelines established from time to time by our Board of Directors.

No shareholder has the contractual right to designate persons to be elected to our Board of Directors, and our Bye-laws provide that directors be elected upon a resolution passed at a duly convened shareholders meeting, to hold office for such term as the shareholders may determine or until their successors are appointed or elected in accordance with our Bye-laws. There is no minimum share ownership or age limit requirement for qualification to serve as a member of our Board of Directors.

We have determined that each of our directors, except for Dr. Mike Chang, our Chief Executive Officer, and Dr. Yueh-Se Ho, our Chief Operating Officer, is an “independent director” under the current corporate governance rules of the NASDAQ Global Select Market.

Board Meetings and Committees; Annual Meeting Attendance

Our Board of Directors met a total of 15 times during the fiscal year ended June 30, 2018, including regular scheduled meetings and special meetings called in connection with reviewing time-sensitive matters. During the fiscal year ended June 30, 2018, each director attended or participated in 93 percent (93%) of the aggregate of (i) the total number of meetings of the Board of Directors during the period for which he has been a director and (ii) the total number of meetings held by all committees of the Board on which the director served during fiscal year 2018.  All of our Board members attended our 2017 annual general meeting of shareholders.

Committees of the Board of Directors

We have three standing committees: an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. We believe that the composition of these committees meets the criteria for independence, and the functioning of these committees complies with, the applicable requirements of the Sarbanes-Oxley Act of 2002, as amended, the current rules of the NASDAQ Global Select Market and applicable SEC rules and regulations. The written charters for our Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee are available at the Investor Relations section of our website at http://investor.aosmd.com/.  The contents of this website are not a part of the Proxy Statement.

Each committee has the composition and responsibilities described below:

Audit Committee

Our Audit Committee consists of Michael L. Pfeiffer, Robert I. Chen and Michael J. Salameh.  The Audit Committee is chaired by Mr. Pfeiffer. Our Board of Directors has determined that Mr. Pfeiffer is an Audit Committee financial expert, as defined by the rules and regulations promulgated by the SEC.  Our Audit Committee held six meetings during fiscal year 2018. The Audit Committee's responsibilities include:

• assisting our Board of Directors in its oversight of the integrity of our financial statements, risk management and internal control over financial reporting;

• retaining and setting compensation of our independent registered public accounting firm (“independent auditors”), evaluating and monitoring its performance, and as appropriate, discharging our independent auditors;

• reviewing and approving all audit and non-audit services of our independent auditors;

• reviewing and discussing with management and our independent auditors our financial statements included in public filings;

• discussing with our independent auditors significant financial reporting issues in connection with the preparation of our financial statements;

9

•resolving any disagreements between management and our independent auditors regarding financial reporting;

•overseeing our disclosure controls and procedures; and

•reviewing and approving related party transactions.

Compensation Committee

Our Compensation Committee consists of Michael J. Salameh, Robert I. Chen, Dr. Lucas S. Chang and Dr. King Owyang.  Our Compensation Committee is currently chaired by Mr. Salameh.  Our Compensation Committee held four meetings during fiscal year 2018. The Compensation Committee's responsibilities include:

• establishing compensation arrangements and incentive goals for executive officers;

• evaluating the performance of executive officers and awarding incentive compensation and adjusting compensation arrangements as appropriate;

• reviewing and recommending actions to the Board of Directors with respect to the compensation of all directors;

• administering our incentive and equity-based plans and programs and otherwise exercising the authority of the Board with respect to such plans and programs; and

• reviewing and approving and, when appropriate, recommending to the Board for approval, any employment agreements and any severance arrangements or plans, including any benefits to be provided in connection with a change in control, for the Chief Executive Officer and other executive officers.

The Compensation Committee is authorized to engage independent compensation consultants and other professionals to assist in the design, formulation, analysis and implementation of compensation programs for the Company’s executive officers and other key employees. The Compensation Committee retained the services of Compensia, Inc., a national compensation consulting firm ("Compensia") to provide advice and recommendations regarding the compensation of the Company’s executive officers and other senior officers and the compensation of our non-employee directors for fiscal year 2018. Compensia did not perform any services on behalf of management or the Company during that fiscal year.

The Compensation Committee has determined that Compensia is independent and that Compensia's work did not raise any conflict of interest. The Compensation Committee made such determination primarily on the basis of the six factors for assessing independence and identifying potential conflicts of interest that are set forth in Rule 10C-1(b)(4) under the Securities Exchange Act of 1934, as amended.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee currently consists of Dr. King Owyang, Dr. Lucas S. Chang and Robert I. Chen.  The Nominating and Corporate Governance Committee is chaired by Dr. King Owyang. Our Nominating and Corporate Governance Committee did not hold any meeting during fiscal year 2018 but has acted once by unanimous written consent. The Nominating and Corporate Governance Committee's responsibilities include:

• recommending to the board of directors the composition and operations of the board;

• identifying individuals qualified to serve as members of the board, and identifying and recommending that the board select the director nominees for the next annual meeting of shareholders and fill vacancies on the board;

• recommending to the board the responsibilities of each board committee, the composition and operation of each board committee and the director nominees for assignment to each board committee; and

• reviewing with the Board the Company’s management succession plans.

Leadership Structure of the Board

Dr. Mike Chang is our Chief Executive Officer and Chairman of the Board of Directors.  Dr. Chang has extensive

10

knowledge of the power semiconductor industry and an in-depth understanding of our strategic initiatives and day-to-day operations, which make him well suited to set the agenda and lead the discussions at board meetings.  He also facilitates communications between the Board and management by ensuring a regular flow of information, thereby enhancing the Board's ability to make informed decisions on critical issues facing our company. In addition, the Board has appointed a lead independent director, Mr. Michael J. Salameh. The lead independent director presides over all executive sessions of independent directors and coordinates activities and communications between the management and independent directors. He also has the responsibility to serve as a liaison between independent directors and the Chairman, communicate with major shareholders as appropriate, and review and approve scheduling of Board meetings and executive sessions.

To ensure a strong independent Board of Directors, five (5) out of the total seven (7) members of our Board following the Annual Meeting are non-employee and independent directors.  The Board of Directors holds executive sessions where only independent directors attend, and these executive sessions provide an effective method to perform oversight and advisory functions of the Board.  In addition, our Audit, Compensation and Nominating and Corporate Governance Committees consist solely of independent directors.  We believe that the board leadership described above is the best structure to lead us in the achievement of our goals and objectives and establishes an effective balance between management leadership and appropriate oversight by independent directors.

Oversight of Risk Management by the Board

One of the key functions of our Board of Directors is informed oversight of our risk management process. The Board administers this oversight function directly through the Board of Directors as a whole, through various standing committees of the Board that address risks inherent in their respective areas of oversight, as well as through our newly appointed lead independent director. In particular, our Board of Directors is responsible for monitoring and assessing strategic and operational risk exposure, including risks associated with acquisition of significant assets, changes in business models, major corporate transactions and market conditions in the semiconductor industry.  Our Audit Committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee provides general oversight of our financial reporting, internal controls and audit functions. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance guidelines and is primarily responsible for assessing the risks associated with corporate governance practices, the independence of our directors, and management succession plans.

Nominations for Election of Directors

Director Qualifications

The Nominating and Corporate Governance Committee utilizes a variety of criteria to evaluate the qualifications and skills necessary to serve as members of our Board of Directors. The Nominating and Corporate Governance Committee may assess character, judgment, diversity, business acumen, scientific expertise, familiarity with issues affecting the semiconductor industry and other backgrounds and attributes that are needed to help strengthen and balance the Board of Directors. Other qualifications will be determined on a case-by-case basis, depending on whether the Nominating and Corporate Governance Committee desires to fill a vacant seat or increase the size of the Board to add new directors.  In addition, while the Nominating and Corporate Governance Committee does not prescribe specific diversity standards, the Committee considers diversity in the context of the Board as a whole and takes into account the personal characteristics and experiences of current and prospective directors that reflect a broad range of perspectives and diverse backgrounds in the Board's decision making process.

Identification and Evaluation of Nominees for Directors

The Nominating and Corporate Governance Committee utilizes a variety of methods for identifying and evaluating nominees for director. The Nominating and Corporate Governance Committee assesses the appropriate size of the Board of Directors, and whether any vacancies on the Board of Directors are expected due to retirement or otherwise.  In the event that vacancies are anticipated, or otherwise arise, the Nominating and Corporate Governance Committee considers various potential candidates for director. Candidates may come to the attention of the Nominating and Corporate Governance Committee through current members of the Board of Directors, executive officers, professional search firms, shareholders or other persons. These candidates are evaluated at regular or special meetings of the Nominating and Corporate Governance Committee, and may be considered at any point during the year. The Nominating and Corporate Governance Committee recommends the director nominees to our Board of Directors for approval for election at each annual general meeting of shareholders. Under our Bye-Laws, any director appointed by our Board of Directors is subject to re-election by shareholders at our next annual

11

general meeting of shareholders. The nominees for election at this annual general meeting were recommended and approved unanimously by members of our Nominating and Corporate Governance Committee and Board of Directors, respectively.

A shareholder seeking to recommend a prospective nominee for the Nominating and Corporate Governance Committee's consideration should submit the candidate's name and qualifications to our Corporate Secretary at our business office in the United States at 475 Oakmead Parkway, Sunnyvale, California 94085.  The Nominating and Corporate Governance Committee will consider a properly submitted shareholder nomination that meets the requirements under our Bye-laws and applicable U.S. federal securities laws.  Our Bye-laws require, among other things, an advance written notice of the nomination in writing of not less than sixty (60) nor more than one hundred and eighty (180) days from the date of the annual general meeting.  This notice must also include certain information relating to the nominee and the nominating shareholders, as described in more detail below in “Future Shareholder Proposals and Nominations for the 2019 Annual General Meeting.”

Shareholder Communication with our Board of Directors

Although we do not have a formal policy regarding communications with the Board of Directors, shareholders may communicate with the Board of Directors, including the independent directors, by sending a letter to Alpha and Omega Semiconductor Limited, Board of Directors, c/o Investor Relations, Alpha and Omega Semiconductor, Inc., 475 Oakmead Parkway, Sunnyvale, CA 94085.  Shareholders may also direct their submission to a particular member of the Board of Directors.

Code of Ethics

Our Board of Directors has adopted the Code of Business Conduct and Ethics that applies to members of senior management, including the Chief Executive Officer and Chief Financial Officer, as well as all other employees of the Company.  Our Code of Business Conduct and Ethics is publicly available on our website athttp://investor.aosmd.com/governance.cfm. In the event that we make any amendments to or grant any waivers of, a provision of the Code of Ethics that applies to the principal executive officer, principal financial officer, or principal accounting officer that requires disclosure under applicable SEC rules, we intend to disclose such amendment or waiver and the reasons therefore, on our website at www.aosmd.com, in the Investors section.

COMPENSATION OF NON-EMPLOYEE DIRECTORS

Our non-employee director compensation policy as in effect at the beginning of fiscal year 2018 provided for the following cash and equity compensation:

Cash Retainer and Fees: Each non-employee director serving as a member of the Board at the beginning of the Company's fiscal year will be eligible to receive an annual retainer of $40,000.  In addition, each non-employee director serving as the chairperson of a committee of the Board will be eligible to receive an additional retainer as follows: Audit Committee - $25,000; Compensation Committee - $15,000; and Nominating and Governance Committee - $15,000. Each non-employee director serving as a member of a committee of the Board will be eligible to receive an additional retainer as follows: Audit Committee - $12,000; Compensation Committee - $7,500; Nominating and Governance Committee - $5,000; and Lead Independent director - $15,000. Non-employee directors will not receive any additional compensation for attending regular Board or committee meetings. However, with respect to special meetings of the Board or a committee, the Board shall determine whether such meetings will be eligible for payment of special fees, and if so, each non-employee director will receive $2,000 for a meeting attended in person and $1,000 for a meeting attended via teleconference.

Equity Grants: Each individual who is elected by the Company’s shareholders to serve as a non-employee director at the Company’s Annual Shareholders Meeting and each individual who is to continue to serve as a non-employee director following such meeting whether or not that individual is standing for re-election at that meeting, will be granted on the date of such meeting, an award of restricted stock units under the Automatic Grant Program of the 2009 Share Option/Share Issuance Plan (the "Plan"). The number of shares subject to each such annual award will be determined by dividing $95,000 by the Average Per Share Price, up to a maximum of 10,000 shares. The Average Per Share Price for an award means the average closing price per common share over the 90 day-period immediately prior to the date of grant of the award. The award will vest in four (4) equal quarterly installments upon the non-employee director’s completion of each quarter of Board service following the grant date; provided, however, that if the Company’s Annual Shareholders Meeting for the year following the year of grant occurs prior to the end of the one-year period measured from the grant date, the last quarterly installment will become vested upon the date of such subsequent Annual Shareholders Meeting, provided, the Non-Employee Director continues in Board service until such date. The award (to the extent outstanding) will vest in full (i) upon the non-employee director’s termination of Board service by reason of death or permanent disability (as defined in the Plan) and (ii) immediately prior to the consummation of a

12

Change in Control (as defined in the Plan). Shares that vest under a restricted stock unit award will be issued on the earlier of (i) the date of the Annual Shareholders Meeting that is coincident with or next following the applicable vesting date or (ii) the date of the non-employee director’s termination of Board service. Shares that vest upon a Change in Control will be issued as soon as practicable following the Change in Control.

Reimbursements: All non-employee directors receive reimbursement from the Company for their reasonable expenses of travel (including airfare and ground transportation) to and from meetings of the Board, and reasonable lodging and meal expenses.

PROPOSAL NO. 2

ADVISORY VOTE ON THE COMPENSATION OF THE NAMED EXECUTIVE OFFICERS

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, and Section 14A of the Exchange Act, our shareholders are entitled to vote, on an advisory basis, to approve the compensation of our named executive officers as disclosed in this proxy statement in accordance with the rules of the Securities and Exchange Commission.

We held our last shareholder advisory vote on executive compensation, commonly referred to as a “say-on-pay vote”, at our 2017 Annual General Meeting of Shareholders. At that meeting, our shareholders voted in favor of holding a say-on-pay vote once every year. Therefore, we are holding our say-on-pay vote on an annual basis starting at this year’s Annual Meeting.

We design our executive compensation program to implement our core objectives of attracting and retaining superior executive talent, ensuring executive compensation is substantially dependent on our financial performance and provides incentives for the attainment of our key strategic business objectives and aligning executives' incentives with the creation of shareholder value. The key elements of the compensation program that were in effect during the 2018 fiscal year for the Company's named executive officers are described in detail in the Compensation Discussion and Analysis section of this proxy statement.

The vote on this resolution is not intended to address any specific element of compensation; rather the vote relates to the compensation of our named executive officers, as described in this proxy statement in accordance with the compensation disclosure rules of the Securities and Exchange Commission.

Although this vote is advisory and the outcome is not binding on our Board of Directors, the views expressed by our shareholders, whether through this vote or otherwise, are important to us. As a result, the Board of Directors and the Compensation Committee will carefully review the results of this vote, and they will consider these results in making future decisions about our executive compensation programs and arrangements.

Resolution

The shareholders are being asked to approve by advisory vote the following resolution relating to the compensation of the named executive officers as described in this proxy statement:

“Resolved that the Company's shareholders hereby approve the compensation paid to the Company's executive officers named in the Summary Compensation Table of this proxy statement, as that compensation is disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the various compensation tables and the accompanying narrative discussion included in this proxy statement.”

Board Recommendation: The Board of Directors recommends that you vote FOR the approval, on a non-binding, advisory basis, of the compensation of our named executive officers as disclosed in this proxy statement pursuant to the Securities and Exchange Commission’s compensation disclosure rules.

PROPOSAL NO. 3:

APPROVAL OF THE 2018 OMNIBUS INCENTIVE PLAN

We are asking our shareholders to approve a proposal to adopt the Alpha & Omega Semiconductor Limited 2018 Omnibus Incentive Plan (the “2018 Plan”) pursuant to which 1,265,000 common shares shall be available for issuance to our officers and employees, non-employee directors, as well as consultants and other independent advisors in our employ or service (or the employ or service of our affiliates). The share reserve may be adjusted (and additional or fewer shares may be issued) as described in more detail in the section titled “Securities Subject to 2018 Plan” below. The Board of Directors adopted the 2018 Plan on October 3, 2018, subject to shareholder approval at the Annual Meeting. If approved by the shareholders, the 2018 Plan will become effective as of the date of the shareholder approval (the “Plan Effective Date”).

The 2018 Plan will serve as the successor to our 2009 Share Option/Share Issuance Plan (the “Predecessor Plan”), which is scheduled to terminate by its terms on September 18, 2019. No further awards shall be made under the Predecessor Plan on or after the Plan Effective Date. Each outstanding award under the Predecessor Plan shall remain outstanding under the Predecessor Plan and shall be governed solely by the terms of the documents evidencing such awards. No provision of the 2018 Plan shall be deemed to affect or otherwise modify the rights or obligations of the holders of such outstanding awards under the Predecessor Plan.

Incentive compensation programs play a pivotal role in our effort to attract and retain key personnel essential to our long-term growth and financial success. For that reason, we have structured the 2018 Plan to provide flexibility in designing equity incentive programs with a broad array of equity incentives, such as options, share appreciation rights, share awards, restricted share units, dividend equivalents and other share-based awards, so that we may implement competitive incentive compensation programs for our key employees and non-employee directors. Following shareholder approval of the 2018 Plan, the 2018 Plan will be the only discretionary plan under which new equity awards may be granted to our employees and other service providers. If this proposal is not approved, we would not be able to grant equity awards following termination of the Predecessor Plan. We would accordingly be at a disadvantage against our competitors for recruiting, retaining and motivating individuals critical to our success and could be forced to increase cash compensation, thereby reducing resources available to meet our business needs.

Determination of Share Reserve Under 2018 Plan

If this proposal is approved, 1,265,000 shares will be available for issuance under the 2018 Plan (subject to adjustments described in the titled “Securities Subject to 2018 Plan” below). In determining the number of shares to be authorized for issuance under the 2018 Plan, the Board of Directors considered a number of factors, including the number of shares available under the Predecessor Plan, our past share usage (burn rate), the number of shares needed for future awards and a dilution analysis.

Dilution Analysis

As of August 31, 2018, 1,694,526 shares were available for future awards under the Predecessor Plan. Additional awards may be granted under the Predecessor Plan to new hires in accordance with past practice up to the date of the Annual Meeting; however, no additional grants will be made under the Predecessor Plan after the date of the Annual Meeting if this proposal is approved.

The Company currently has awards outstanding under the Predecessor Plan. As of August 31, 2018, there were 876,978 shares subject to outstanding options under the Predecessor Plan and 2,651,058 shares subject to awards other than options under the Predecessor Plan, as described in the table below.

Plan as of August 31, 2018	Shares Subject to Outstanding Options (1)	Shares Subject to Outstanding Full Value Awards (2)	Shares Available for Future Grant if 2018 Plan is Approved		Total Aggregate Shares
Predecessor Plan	876,978	2,651,058	0	(3)	3,528,036
Shares Available for Future Grant Upon Approval of the 2018 Plan			1,265,000	(4)	1,265,000

(1) As of August 31, 2018, the 876,978 options outstanding had a weighted average exercise price per share of $10.98 and a weighted average life of 3.90 years.

15

(2) Consists of 918,758 shares subject to time-based restricted share units and 1,732,300 shares subject to performance-based restricted share units assuming target performance (which may settle in a range of 0% to 100% of target depending on level of performance attained). Additional awards may be granted to new hires based on past practice under the Predecessor Plan up to the date of the Annual Meeting.

(3) No additional awards will be granted under the Predecessor Plan as of the effective date of the 2018 Plan and the shares that are not subject to awards under the Predecessor Plan as of such date will not be available for issuance under the 2018 Plan.

(4)    The requested share reserve may be adjusted (and additional or fewer shares may be issued) as described in more detail in the section titled “Securities Subject to 2018 Plan” below.

Based on the Company’s common shares outstanding as of August 31, 2018, the 1,265,000 shares under the 2018 Plan represents an overhang of approximately 4.4% of our fully diluted shares. The Company calculates "fully diluted shares" as the total number of shares outstanding, shares underlying outstanding awards and shares available for issuance under future equity awards.

The Board of Directors believes that the number of shares under the 2018 Plan represents a reasonable amount of potential equity dilution, which will allow the Company to continue to grant equity awards which are an important component of our compensation program.

Burn Rate

In connection with our share-based compensation programs, we are committed to using equity incentive awards prudently and within reasonable limits. Accordingly, we closely monitor our share award “burn rate” each year. Our annual burn rate is determined by dividing the number of our common shares subject to time-based awards we grant, or vested in the case of performance-based restricted share units ("PSU"), in a fiscal year by the weighted average number of our common shares outstanding for that fiscal year.

Fiscal Year	Options Granted	RSUs Granted	PSUs Vested	Total Granted or Vested if PSU	Weighted Average Common Share Outstanding	Burn Rate
2018	0	482,397	38,247	520,644	23,901,373	2.2	%
2017	0	446,719	—	446,719	23,526,208	1.9	%
2016	0	466,255	—	466,255	23,451,549	2.0	%
3-Year Average	0	465,124	12,749	477,873	23,293,043	2.1	%

During fiscal year 2018 and 2017, the Company granted PSUs covering 298,000 and 170,000 target shares respectively to its officers and certain other employees. The number of shares to be ultimately earned under the fiscal year 2017 and fiscal year 2018 PSUs is determined based on the level of attainment of predetermined financial goals (not to exceed the target number of shares). Any shares earned based on financial performance vest in four equal annual installments from the first anniversary date after the grant date based on continued service. In fiscal year 2018, 38,247 PSU shares vested (under the fiscal year 2017 PSUs) based on performance and completed service. No PSUs were granted in fiscal year 2016 and no PSU shares vested in fiscal years 2017 and 2016. Up to 25% of the PSUs granted in fiscal year 2018 will vest in March 2019 based on performance and continued service.

16

The following table shows the number of PSUs granted and vested in each fiscal year:

	Number of PSUs
Nonvested at June 30, 2015	—
Granted	—
Vested	—
Forfeited	—
Nonvested at June 30, 2016	—
Granted	170,000
Vested	—
Forfeited	—
Nonvested at June 30, 2017	170,000
Granted	298,050
Vested	(38,247	)
Forfeited	(7,503	)
Nonvested at June 30, 2018	422,300

Based on our current equity award practices, the Board of Directors estimates that the authorized shares under the 2018 Plan may be sufficient to provide us with an opportunity to grant equity awards for approximately 1 to 2 years, in amounts determined appropriate by the Compensation Committee or the Board of Directors, which will administer the 2018 Plan (as discussed below). This is only an estimate, and circumstances could cause the share reserve to be used more quickly or more slowly. These circumstances include, but are not limited to, the future price of our common shares, the mix of options and full value awards provided as long-term incentive compensation, grant amounts provided by our competitors, payout of performance-based awards in excess of target in the event of superior performance, hiring activity, and promotions during the next few years.

Highlights of the 2018 Plan

The 2018 Plan contains a number of provisions that we believe are consistent with best practices in equity compensation and which protect the shareholders’ interests, as described below.

No evergreen authorization: The 2018 Plan does not have an evergreen provision, which would have permitted an increase in the share pool without further shareholder approval.

No automatic vesting upon a change in control: The 2018 Plan allows for an acquiring corporation to assume outstanding awards, and if awards are assumed, they will generally not accelerate on the change in control. If awards are not assumed, the vesting of such awards will be accelerated (with performance-based awards vesting based on actual performance attainment as of the date of the change in control or on a pro-rated basis for time elapsed in the ongoing performance period based on target level). The plan administrator also has the discretion to take alternative actions such as accelerating the vesting of outstanding awards on a termination following a change in control or requiring that participants exchange outstanding awards for cash.

Prohibition on repricings: The 2018 Plan prohibits the repricing of options or share appreciation rights, the cancellation and replacement of options or share appreciation rights with a grant with a lower exercise price, or a cash buyout of an underwater option or share appreciation right (except as permitted in a change in control or in the case of a corporate transaction as described in the section titled “Changes in Capitalization” below).

No discounted options or share appreciation rights: Options and share appreciation rights must have an exercise price or base price at or above fair market value per share on the date of grant.

Limit on director pay: The maximum aggregate grant date fair value (computed as of the date of grant in accordance with applicable financial accounting rules) of all awards made to a non-employee director under the 2018 Plan in a single calendar year, taken together with any cash payments (including the annual retainer and any other compensation) paid to such non-employee director in respect of such calendar year, shall not exceed $750,000 ($1,000,000 in the initial year of election or appointment) in total value.

No tax gross-ups: The 2018 Plan does not provide for any tax gross-ups.

17

No liberal change-in-control definition: The 2018 Plan defines change in control based on the consummation of the transaction rather than the announcement or shareholder approval of the transaction.

Limitation on dividends and dividend equivalents: Any dividends or dividend equivalents payable in connection with an award will be subject to the same restrictions as the underlying award and will not be paid until and unless such award vests.

Administered by an independent committee: The 2018 Plan will be administered by the Compensation Committee of our Board of Directors, which consists entirely of independent directors. The Compensation Committee may delegate its authority to a subcommittee or officer, as described in more detail below.

Summary Description of 2018 Omnibus Incentive Plan

The principal terms and provisions of the 2018 Plan are set forth below. The summary, however, is not intended to be a complete description of all the terms of the 2018 Plan and is qualified in its entirety by reference to the complete text of the 2018 Plan, filed with this Proxy Statement as Appendix A.

Types of Awards. The following types of awards may be granted under the 2018 Plan: options, share appreciation rights, share awards, restricted share units, dividend equivalent rights and other share-based awards. The principal features of each type of award are described below.

Administration. The Compensation Committee has the exclusive authority to administer the 2018 Plan with respect to awards made to our executive officers and non-employee directors and has the authority to make awards under the 2018 Plan to all other eligible individuals. However, our Board of Directors may at any time appoint a secondary committee of one (1) or more members of the Board of Directors to have separate but concurrent authority with the Compensation Committee to make awards under the 2018 Plan to individuals other than executive officers and non-employee directors. The Board of Directors or the Compensation Committee may also delegate authority to administer the 2018 Plan with respect to such individuals to one or more officers of the Company.

The term “plan administrator,” as used in this summary, will mean our Compensation Committee, the Board of Directors, any secondary committee and any delegates thereof, to the extent each such entity or person is acting within the scope of its administrative authority under the 2018 Plan.

Eligibility. Officers and employees, non-employee directors, as well as consultants and other independent advisors, in our employ or service or in the employ or service of our affiliates (whether now existing or subsequently established) are eligible to participate in the 2018 Plan. As of August 31, 2018, approximately 3,522 employees (including four executive officers) and 5 non-employee directors would have been eligible to participate in the 2018 Plan had it been in effect on such date. For purposes of the 2018 Plan, an affiliate means a parent corporation or any entity in which the Company has an equity interest.

Securities Subject to 2018 Plan. Subject to the capitalization adjustments and the add back provisions related to outstanding awards, each as described below, an aggregate of up to 1,265,000 shares shall be reserved for issuance under the 2018 Plan.

Shares subject to outstanding awards under the 2018 Plan and awards granted under the Predecessor Plan that expire, are forfeited or cancelled or otherwise terminate prior to the issuance of the shares subject to those awards or are settled in cash will be available for subsequent issuance under the 2018 Plan.

In addition, the following share counting procedures will apply in determining the number of common shares available from time to time for issuance under the 2018 Plan:

• Should the exercise price of an option or any withholding taxes incurred in connection with the exercise of an option or share appreciation right granted under the 2018 Plan be paid in common shares (whether through the withholding of a portion of the otherwise issuable shares or through tender of actual outstanding shares), then in each such case, the tendered or withheld shares will not be added to the shares reserved for issuance under the 2018 Plan.

• Should common shares be withheld by us, or if shares are tendered by the participant, in each case in satisfaction of the withholding taxes incurred in connection with the issuance, vesting or settlement of an award (other than an option or share appreciation right) granted under the 2018 Plan or the Predecessor Plan, then in each case the number of shares so tendered or withheld will be added to the common shares available for issuance under the 2018 Plan.

18

• Upon the exercise of any share appreciation right granted under the 2018 Plan, the share reserve will be reduced by the gross number of shares subject to the award.

The maximum number of common shares which may be issued pursuant to options intended to qualify as incentive stock options under the federal tax laws shall be limited to 1,265,000.

The plan administrator may grant awards in assumption of, or in substitution for, outstanding awards previously granted by an entity acquired by the Company or with which the Company combines. Such substitute awards will not reduce the common shares authorized for issuance under the 2018 Plan (but will count against the aggregate number of incentive stock options available for awards, as described above). Additionally, subject to applicable stock exchange requirements, if the acquired company’s equity plan has shares available, such shares may be available for grant under the 2018 Plan, which will not reduce (or be added back to) the shares authorized for issuance under the 2018 Plan.

The common shares issuable under the 2018 Plan may be made available from our authorized but unissued common shares or from common shares that we acquire, including shares purchased on the open market.

Participant Award Limits

The maximum number of common shares which may be issued pursuant to awards that are settled in shares and granted to any person under the 2018 Plan in any fiscal year shall not exceed 800,000 shares.

In addition, the maximum aggregate grant date fair value (computed as of the date of grant in accordance with applicable financial accounting rules) of all awards made to a non-employee director under the 2018 Plan in a single calendar year, taken together with any cash payments (including the annual retainer and any other compensation) paid to such non-employee director in respect of such calendar year, shall not exceed $750,000 ($1,000,000 in the non-employee director’s initial year of election or appointment) in total value.

Awards. The plan administrator has complete discretion to determine (a) which eligible individuals are to receive awards,(b) the type, size, terms and conditions of the awards to be made, (c) the time or times when those awards are to be granted,(d) the number of shares or amount of payment subject to each such award, (e) the time when the award is to become exercisable, (f) the status of any granted option as either an incentive stock option or a non-statutory option under the federal tax laws, (g) the maximum term for which the award is to remain outstanding, (h) the vesting and issuance schedules applicable to the shares which are the subject of the award, (i) the cash consideration (if any) payable per share subject to the award and the form of payment in which the award is to be settled and (j) with respect to performance-based awards, the amount payable at one or more levels of attained performance, the payout schedule and the form of payment.

Share Options. Each granted option will have an exercise price per share determined by the plan administrator, but the exercise price will not be less than one hundred percent (100%) of the fair market value of the option shares on the grant date. No granted option will have a term in excess of ten (10) years. The shares subject to each option will generally vest in one or more installments over a specified period of service measured from the grant date or upon the achievement of pre-established performance objectives. However, one or more options may be structured so that they will be immediately exercisable for any or all of the option shares. The shares acquired under such immediately exercisable options will be subject to repurchase by us, at the lower of the exercise price paid per share or the fair market value per share, if the optionee ceases service prior to vesting in those shares. Payment of the exercise price may be paid in one or more of the following forms as determined by the plan administrator: cash, our common shares, through a cashless exercise procedure pursuant to which the optionee effects a same-day exercise of the option and sale of the purchased shares through a broker in order to cover the exercise price for the purchased shares and the applicable withholding taxes and/or through a net exercise procedure pursuant to which we withhold a number of shares otherwise issuable upon exercise of the option having a value equal to the exercise price and applicable withholding taxes.

Upon cessation of service, the optionee will have a limited period of time in which to exercise his or her outstanding options to the extent exercisable for vested shares. The plan administrator will have complete discretion to extend the period following the optionee’s cessation of service during which his or her outstanding options may be exercised, provide for continued vesting during the applicable post-service exercise period and/or accelerate the exercisability or vesting of options in whole or in part. Such discretion may be exercised at any time while the options remain outstanding,

19

Share Appreciation Rights. The 2018 Plan allows the issuance of two types of share appreciation rights:

• Tandem share appreciation rights granted in conjunction with options, which provide the holders with the right to surrender the related option grant for an appreciation distribution from us in an amount equal to the excess of (i) the fair market value of the vested common shares subject to the surrendered option over (ii) the aggregate exercise price payable for those shares.

• Stand-alone share appreciation rights, which allow the holders to exercise those rights as to a specific number of our common shares and receive in exchange an appreciation distribution from us in an amount equal to the excess of (i) the fair market value of the common shares as to which those rights are exercised over (ii) the aggregate exercise price in effect for those shares. The exercise price per share may not be less than the fair market value per underlying common share on the date the stand-alone share appreciation right is granted, and the right may not have a term in excess of ten (10) years.

The appreciation distribution on any exercised share appreciation right will be paid in (i) cash, (ii) our common shares or (iii) a combination of cash and our common shares. Upon cessation of service with us, the holder of a share appreciation right will have a limited period of time in which to exercise that right to the extent exercisable at that time. The plan administrator has complete discretion to extend the period following the holder’s cessation of service during which his or her outstanding share appreciation rights may be exercised, provide for continued vesting during the applicable post-service exercise period and/or accelerate the exercisability or vesting of share appreciation rights in whole or in part. Such discretion may be exercised at any time while the share appreciation rights remain outstanding.

Repricing. The plan administrator may not implement any of the following repricing programs (except in the case of a corporate transaction as described in the section titled “Changes in Capitalization” below): (i) the cancellation of outstanding options or share appreciation rights in return for new options or share appreciation rights with a lower exercise price per share, (ii) the cancellation of outstanding options or share appreciation rights with exercise prices per share in excess of the then current fair market value per common share for consideration payable in cash, other awards or our equity securities (except in the event of a change in control) or (iii) the direct reduction of the exercise price in effect for outstanding options or share appreciation rights.

Share Awards and Restricted Share Units. Our common shares may be issued under the 2018 Plan subject to performance or service vesting requirements established by the plan administrator or as a fully-vested bonus for past services without any cash outlay required of the recipient. Our common shares may also be issued under the 2018 Plan pursuant to restricted share units, which entitle the recipients to receive those shares upon the attainment of designated performance goals or the completion of a prescribed service period or upon the expiration of a designated time period following the vesting of those units, including (without limitation), a deferred distribution date following the termination of the recipient’s service with us.

The plan administrator will have the discretionary authority to structure one or more such awards so that the common shares subject to those awards (or cash, as applicable) will vest only upon the achievement of certain pre-established corporate performance goals which may be based on one or more of the following criteria: (i) cash flow; (ii) earnings (including earnings before interest and taxes, earnings before taxes, earnings before interest, taxes, depreciation, amortization and charges for share-based compensation, earnings before interest, taxes, depreciation and amortization, and net earnings); (iii) earnings per share; (iv) growth in earnings or earnings per share; (v) share price; (vi) return on equity or average shareholder equity; (vii) total shareholder return or growth in total shareholder return either directly or in relation to a comparative group; (viii) return on capital; (ix) return on assets or net assets; (x) invested capital, required rate of return on capital or return on invested capital; (xi) revenue, growth in revenue or return on sales; (xii) income or net income; (xiii) operating income, net operating income or net operating income after tax; (xiv) profit, operating profit or net operating profit; (xv) operating margin or gross margin; (xvi) return on operating revenue or return on operating profit; (xvii) sales or bookings targets; (xviii) billings; (xix) expense or expense control and/or cost reductions; (xx) capital expenditure; (xxi) improvement in or attainment of working capital levels; (xxii) market share or penetration; (xxiii) debt reduction or debt levels (xxiv) project and product measures; (xxv) operation performance; (xxvi) systems and systems improvement; (xxvii) manufacturing; (xxviii) manufacturing efficiencies, improvement or variances; (xxix) delivery performance; (xxx) product and technology development; (xxxi) manufacturing and operational achievements; (xxxii) capacity utilization or milestones; (xxxiii) environmental goals or management; (xxxiv) market capitalization, (xxxv) application approvals, (xxxvi) litigation and regulatory resolution goals, (xxxvii) implementation, completion or attainment of key projects, (xxviii) product sales or milestones, (xxxix) budget comparisons, (xl) growth in shareholder value relative to the growth of a peer group or index; (xli) development and implementation of strategic plans and/or organizational restructuring goals; (xlii) development and implementation of risk and crisis management programs; (xli) improvement in workforce diversity; (xlii) compliance requirements and compliance relief; (xliii) productivity goals; (xliv) workforce management and succession planning goals; (xlv) economic value added (including typical adjustments consistently

20

applied from generally accepted accounting principles required to determine economic value added performance measures); ( xlvi) contract win, renewal or extension; (xlvii) design win; (xlviii) delivery and/or design schedule; (xlix) development or milestones in new generation of products or technologies; (l) product technology or quality; (li) leadership metrics; recruiting and maintaining personnel, employee retention, measures of customer satisfaction, employee satisfaction or staff development; (li) development or marketing collaborations, formations of joint ventures or partnerships or the completion of other similar transactions intended to enhance the Company’s revenue or profitability or enhance its customer base; (lii) merger and acquisitions; and (liii) other similar criteria consistent with the foregoing. In addition, such performance criteria may be based upon the attainment of specified levels of the Company’s performance under one or more of the measures described above relative to the performance of other entities and may also be based on the performance of any of the Company’s business units or divisions or any parent or subsidiary. Each applicable performance goal may include a minimum threshold level of performance below which no award will be earned, levels of performance at which specified portions of an award will be earned and a maximum level of performance at which an award will be fully earned. Each applicable performance goal may be structured at the time of the award to provide for appropriate adjustment for one or more of the following items: (A) asset impairments or write-downs; (B) litigation or claim judgments or settlements; (C) the effect of changes in tax law, accounting principles or other such laws or provisions affecting reported results; (D) accruals for reorganization and restructuring programs; (E) the operations of any business acquired by the Company; (F) the divestiture of one or more business operations or the assets thereof; (G) the effects of any corporate transaction, such as a merger, consolidation, separation (including spin-off or other distributions of stock or property by the Company) or reorganization; (H) restructurings, discontinued operations, extraordinary items, and other unusual, infrequently occurring or non-recurring charges or events; (I) acquisitions or divestitures; (J) change in the corporate structure or capital structure of the Company; (K) an event either not directly related to the operations of the Company, parent, subsidiary, division, business segment or business unit or not within the reasonable control of management; (L) foreign exchange gains and losses; (M) a change in the fiscal year of the Company; (N) the refinancing or repurchase of bank loans or debt securities; (O) unbudgeted capital expenditures; (P) the issuance or repurchase of equity securities and other changes in the number of outstanding shares; (Q) conversion of some or all of convertible securities to common stock; (R) any business interruption event; (S) the cumulative effects of tax or accounting changes in accordance with GAAP; (T) the effect of changes in other laws or regulatory rules affecting reported results; and (U) any other adjustment consistent with the operation of the 2018 Plan. The Compensation Committee may also grant awards that are based on performance goals other than those set forth above.

Should the participant cease to remain in service while holding one or more unvested shares or should the performance objectives not be attained with respect to one or more such unvested shares, then those shares will be immediately subject to cancellation. Outstanding restricted share units will automatically terminate, and no common shares will actually be issued in satisfaction of those awards, if the performance goals or service requirements established for such awards are not attained. The plan administrator, however, will have the discretionary authority to issue common shares in satisfaction of one or more outstanding awards, or waive the surrender and cancellation of one or more unvested common shares, as to which the designated performance goals or service requirements are not attained.

Dividend Equivalent Rights. The plan administrator may provide a participant as part of an award (other than options or share appreciation rights) with dividends or dividend equivalents, payable in cash, common shares, or a combination of cash and common shares, on such terms as determined by the plan administrator. However, any dividend or dividend equivalent will only be paid if the underlying award vests and will be subject to a risk of forfeiture to the same extent as the underlying award.

Other Share-Based Awards. Under the 2018 Plan, the plan administrator may grant other types of awards that are denominated in common shares to anyone eligible to participate in the 2018 Plan. The plan administrator will determine the terms and conditions of such awards.

New Plan Benefits

No awards have been granted under the 2018 Plan. It is expected that our non-employee directors will receive an equity award on or following the date of the Annual Meeting; however, the amount and terms of such awards have not been determined. Any awards following approval of this proposal to other participants shall be at the discretion of the plan administrator. Accordingly, the benefits or amounts that may be received by or allocated to each of (i) the officers listed in the Summary Compensation Table, (ii) each of the nominees for election as a director, (iii) all non-employee directors as a group, (iv) all of our present executive officers as a group, and (v) all of our employees, including all other current officers, as a group under the 2018 Plan are not determinable at this time.

General Provisions

21

Change in Control. In the event we should experience a change in control, the following provisions are in effect for all outstanding awards under the 2018 Plan, unless provided otherwise in an award agreement entered into with the participant:

•Each outstanding award may be assumed, substituted, replaced with a cash retention program that preserves the intrinsic value of the award and provides for subsequent payout in accordance with the same vesting schedule applicable to the award or otherwise continued in effect by the successor corporation.

•To the extent an award is not so assumed, substituted, replaced or continued, the award will automatically accelerate in full (with vesting of performance-based awards to be determined with reference to actual performance attained as of the change in control or on a pro-rated basis for time elapsed in the ongoing performance period based on target level).

•The plan administrator has complete discretion to grant one or more awards which will vest in the event the individual’s service with us or the successor entity is terminated within a designated period following a change in control transaction in which those awards are assumed or otherwise continued in effect.

•Unless the plan administrator establishes a different definition for one or more awards, a change in control will be deemed to occur for purposes of the 2018 Plan in the event (a) we are acquired by merger or asset sale or (b) there occurs any transaction pursuant to which any person or group of related persons becomes directly or indirectly the beneficial owner of securities possessing more than fifty percent (50%) of the total combined voting power of our outstanding securities or (c) there is a change in the majority of the Board of Directors effected through one or more contested elections for board membership.

Changes in Capitalization. In the event any change is made to the outstanding common shares by reason of any share split, share dividend, recapitalization, combination of shares, exchange of shares, spin-off transaction, extra-ordinary distribution (whether in cash, securities or other property) or other change in corporate structure effected without our receipt of consideration or should the value of our outstanding common shares be substantially reduced by reason of a spin-off transaction or extraordinary dividend or distribution or should there occur any merger, consolidation, reincorporation or other reorganization, equitable adjustments will be made to: (i) the maximum number and/or class of securities issuable under the 2018 Plan; (ii) the maximum number and/or class of securities for which incentive options may be granted under the 2018 Plan; (iii) the maximum number and/or class of securities for which any one (1) person may be granted common share-denominated awards under the 2018 Plan per fiscal year; (iv) the number and/or class of securities and the exercise price per share in effect for outstanding award and the cash consideration (if any) payable per share. Such adjustments will be made in such manner as the plan administrator deems appropriate.

Valuation. The fair market value per common share on any relevant date under the 2018 Plan is deemed to be equal to the closing selling price per share on that date as determined on the NASDAQ Global Select Market. As of August 31, 2018, the fair market value of a common share determined on such basis was $14.21 per share.

Shareholder Rights and Transferability. No optionee has any shareholder rights with respect to the option shares until such optionee has exercised the option and paid the exercise price for the purchased shares. The holder of a share appreciation right will not have any shareholder rights with respect to the shares subject to that right unless and until such person exercises the right and becomes the holder of record of any common shares distributed upon such exercise. Options are not assignable or transferable other than by will or the laws of inheritance following optionee’s death, and during the optionee’s lifetime, the option may only be exercised by the optionee. However, the plan administrator may structure one or more non-statutory options under the 2018 Plan so that those options will be transferable during optionee’s lifetime to one or more members of the optionee’s family or to a trust established for the optionee and/or one or more such family members or to the optionee’s former spouse, to the extent such transfer is in connection with the optionee’s estate plan or pursuant to a domestic relations order. Stand-alone share appreciation rights will be subject to the same transferability restrictions applicable to non-statutory options.

A participant will have full shareholder rights with respect to any common shares issued to him or her under the 2018 Plan, whether or not his or her interest in those shares is vested. A participant will not have any shareholder rights with respect to the common shares subject to restricted share units until that award vests and the common shares are actually issued thereunder. However, dividend-equivalent units may be paid or credited, either in cash or in actual or phantom common shares, on outstanding restricted share units, subject to such terms and conditions as the plan administrator may deem appropriate. Notwithstanding the foregoing, any dividends or dividend equivalents payable in connection with an award will be subject to the same restrictions as the underlying award and will not be paid until and unless such award vests.

Withholding taxes. A participant shall be required to pay to the Company, and the Company shall have the right to withhold, from any cash, shares or other securities or property issuable under any award or from any other compensation, any required withholding or any other applicable taxes or other amounts due in respect of an award. The plan administrator may

22

provide one or more holders of awards under the 2018 Plan with the right to have us withhold a portion of the shares otherwise issuable to such individuals in satisfaction of the withholding taxes to which they become subject in connection with the issuance, exercise or settlement of those awards. Alternatively, the plan administrator may allow such individuals to deliver previously acquired common shares in payment of such withholding tax liability.

Deferral Programs. The plan administrator may structure one or more awards so that the participants may be provided with an election to defer the compensation associated with those awards for federal income tax purposes.

The plan administrator may also implement a non-employee director retainer fee deferral program that allows the non-employee directors the opportunity to elect to convert the Board and Board committee retainer fees to be earned for a year into restricted share units that defer the issuance of the common shares that vest under those units until a permissible date or event under Internal Revenue Code Section 409A.

To the extent we maintain one or more separate non-qualified deferred compensation arrangements which allow the participants the opportunity to make notional investments of their deferred account balances in common shares, the plan administrator may authorize the share reserve under the Plan to serve as the source of any common shares that become payable under those deferred compensation arrangements.

Clawback / Forfeiture. All awards shall be subject to any clawback, recoupment or other similar policy adopted by the Board of Directors, and any cash, common shares or other property or amounts due, paid or issued to a participant shall be subject to the terms of such policy.

Amendment and Termination. Our Board of Directors may amend or modify the 2018 Plan at any time subject to shareholder approval to the extent required under applicable law or regulation or pursuant to the listing standards of the stock exchange on which our common shares are at the time primarily traded. Unless sooner terminated by our Board of Directors, the 2018 Plan will terminate on the earliest of (i) the date immediately preceding the tenth anniversary of the Plan Effective Date, (ii) the date on which all shares available for issuance under the 2018 Plan have been issued as fully-vested shares or (iii) the termination of all outstanding awards in connection with certain changes in control or ownership.

Summary of Federal Income Tax Consequences

The following is a summary of the Federal income taxation treatment applicable to us and the participants who receive awards under the 2018 Plan.

Option Grants. Options granted under the 2018 Plan may be either incentive options, which satisfy the requirements of Section 422 of the Internal Revenue Code, or non-statutory options, which are not intended to meet such requirements. The federal income tax treatment for the two types of options differs as follows:

Incentive Options. No taxable income is recognized by the optionee at the time of the option grant, and no taxable income is recognized for regular tax purposes at the time the option is exercised, although taxable income may arise at that time for alternative minimum tax purposes. The optionee will recognize taxable income in the year in which the purchased shares are sold or otherwise made the subject of certain other dispositions. For Federal tax purposes, dispositions are divided into two categories: (i) qualifying, and (ii) disqualifying. A qualifying disposition occurs if the sale or other disposition is made more than two (2) years after the date the option for the shares involved in such sale or disposition is granted and more than one (1) year after the date the option is exercised for those shares. If the sale or disposition occurs before these two periods are satisfied, then a disqualifying disposition will result.

Upon a qualifying disposition, the optionee will recognize long-term capital gain in an amount equal to the excess of (i) the amount realized upon the sale or other disposition of the purchased shares over (ii) the exercise price paid for the shares. If there is a disqualifying disposition of the shares, then the excess of (i) the fair market value of those shares on the exercise date or (if less) the amount realized upon such sale or disposition over (ii) the exercise price paid for the shares will be taxable as ordinary income to the optionee. Any additional gain or loss recognized upon the disposition will be a capital gain or loss.

If the optionee makes a disqualifying disposition of the purchased shares, then we will be entitled to an income tax deduction, for the taxable year in which such disposition occurs, equal to the amount of ordinary income recognized by the optionee as a result of the disposition. We will not be entitled to any income tax deduction if the optionee makes a qualifying disposition of the shares.

23

Non-Statutory Options. No taxable income is recognized by an optionee upon the grant of a non-statutory option. The optionee will in general recognize ordinary income, in the year in which the option is exercised, equal to the excess of the fair market value of the purchased shares on the exercise date over the exercise price paid for the shares, and the optionee will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the optionee with respect to the exercised non-statutory option. The deduction will in general be allowed for our taxable year in which such ordinary income is recognized by the optionee.

Share Appreciation Rights. No taxable income is recognized upon receipt of a share appreciation right. The holder will recognize ordinary income in the year in which the share appreciation right is exercised, in an amount equal to the excess of the fair market value of the underlying shares on the exercise date over the exercise price in effect for the exercised right, and the holder will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the holder in connection with the exercise of the share appreciation right. The deduction will be allowed for the taxable year in which such ordinary income is recognized.

Share Awards. The recipient of unvested common shares issued under the 2018 Plan will not recognize any taxable income at the time those shares are issued but will have to report as ordinary income, as and when those shares subsequently vest, an amount equal to the excess of (i) the fair market value of the shares on the vesting date over (ii) the cash consideration (if any) paid for the shares. The recipient may, however, elect under Section 83(b) of the Internal Revenue Code to include as ordinary income in the year the unvested shares are issued an amount equal to the excess of (i) the fair market value of those shares on the issue date over (ii) the cash consideration (if any) paid for such shares. If the Section 83(b) election is made, the recipient will not recognize any additional income as and when the shares subsequently vest. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the recipient with respect to the unvested shares. The deduction will in general be allowed for our taxable year in which such ordinary income is recognized by the recipient.

Restricted Share Units. No taxable income is recognized upon receipt of restricted share units. The holder will recognize ordinary income in the year in which the shares subject to the units are actually issued to the holder. The amount of that income will be equal to the fair market value of the shares on the date of issuance, and the holder will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the holder at the time the shares are issued. The deduction will be allowed for the taxable year in which such ordinary income is recognized.

Dividend Equivalent Rights. No taxable income is recognized upon receipt of a dividend equivalent right award. The holder will recognize ordinary income in the year in which a dividend or distribution, whether in cash, securities or other property, is paid to the holder. The amount of that income will be equal to the fair market value of the cash, securities or other property received, and the holder will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of the ordinary income recognized by the holder of the dividend equivalent right award at the time the dividend or distribution is paid to such holder. That deduction will be allowed for the taxable year in which such ordinary income is recognized.

Other Share-Based Award. In general, no taxable income is recognized upon receipt of other share-based awards. The holder will recognize ordinary income in the year in which the share-based awards are actually settled, and the participant will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the participant at the time of settlement. The deduction will be allowed for the taxable year in which such ordinary income is recognized.

Section 162(m) of the Code. Prior to 2018, Section 162(m) of the Code imposed a $1 million limit on the amount a public company may deduct for compensation paid to a company’s chief executive officer or any of the company’s three other most highly compensated executive officers (other than the chief financial officer) who are employed as of the end of the year. This limitation did not apply to compensation that meets the tax code requirements for “qualifying performance-based” compensation (i.e., compensation paid only if the individual’s performance meets pre-established objective goals based on performance criteria approved by shareholders, including options).

The performance-based compensation exemption and the exemption of the chief financial officer from Section 162(m)’s deduction limit have been repealed, among other changes, effective for taxable years beginning after December 31, 2017, such that awards paid to our covered executive officers (including our chief executive officer) in excess of $1 million will not be deductible in future years, unless it is grandfathered by qualifying for transition relief applicable to certain arrangements that were in effect as of November 2, 2017 and are not materially modified thereafter.

As in prior years, while deductibility of executive compensation for federal income tax purposes is among the factors the Compensation Committee considers when structuring our executive compensation arrangements, it is not the sole or primary factor considered. We retain the flexibility to authorize compensation that may not be deductible if we believe it is in the best interests of the Company.

Accounting Treatment. Pursuant to the accounting standards under FASB Accounting Standards Codification Topic 718, we will be required to expense all share-based payments, including grants of share options, share appreciation rights, share awards, restricted share units and all other share-based awards under the 2018 Plan. Accordingly, options and share appreciation rights which are granted to our employees and non-employee directors and payable in common shares will have to be valued at fair value as of the grant date under an appropriate valuation formula, and that value will then have to be charged as a direct compensation expense against our reported earnings over the designated vesting period of the award. Share appreciation rights that are to be settled in cash will be subject to variable mark-to-market accounting until the settlement date. For shares issuable upon the vesting of restricted share units awarded under the 2018 Plan, we will be required to amortize over the vesting period a compensation cost equal to the fair market value of the underlying shares on the date of the award. If any other shares are unvested at the time of their direct issuance, then the fair market value of those shares at that time will be charged to our reported earnings ratably over the vesting period. Such accounting treatment for restricted share units and direct share issuances will be applicable whether vesting is tied to service periods or performance goals, although for performance-based awards, the grant date fair value will initially be determined on the basis of the probable outcome of performance goal attainment. The issuance of a fully-vested share bonus will result in an immediate charge to our earnings equal to the fair market value of the bonus shares on the issuance date. Dividends or dividend equivalents paid on the portion of an award that vests will be charged against our retained earnings.

Finally, it should be noted that the compensation expense accruable for performance-based awards under the 2018 Plan will, in general, be subject to adjustment to reflect the actual outcome of the applicable performance goals, and any expenses accrued for such performance-based awards will be reversed if the performance goals are not met, unless those performance goals are deemed to constitute market conditions (i.e., because they are tied to the price of our common shares) under FASB Accounting Standards Codification Topic 718.

Required Vote

Provided a quorum is present, the affirmative vote of holders of a majority of the votes cast in person or represented by proxy and entitled to vote at the Annual Meeting will be required to approve the adoption of the 2018 Plan. Should such approval not be obtained, then the 2018 Plan will not be implemented and awards will continue to be granted under the Predecessor Plan until its termination on September 18, 2019.

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS BELIEVES THAT PROPOSAL THREE IS IN OUR BEST INTERESTS AND IN THE BEST INTERESTS OF OUR SHAREHOLDERS AND RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE 2018 OMNIBUS INCENTIVE PLAN.

UNLESS OTHERWISE INDICATED THEREON, THE ACCOMPANYING PROXY WILL BE VOTED FOR APPROVAL OF THE 2018 OMNIBUS INCENTIVE PLAN. YOUR BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF THE 2018 OMNIBUS INCENTIVE PLAN.

PROPOSAL NO.4:

ADOPTION OF THE 2018 EMPLOYEE SHARE PURCHASE PLAN

We are asking our shareholders to approve a proposal to adopt the Alpha & Omega Semiconductor Limited 2018 Employee Share Purchase Plan (the “Purchase Plan”), under which 1,430,000 common shares will be available for issuance. The Purchase Plan was adopted by the Board of Directors on October 3, 2018, subject to shareholder approval at the Annual Meeting. If approved by the shareholders, the Purchase Plan will become effective as of the date of the shareholder approval (the “Purchase Plan Effective Date”).

The Purchase Plan is designed to allow eligible employees of the Company and its participating parent and subsidiaries (whether now existing or subsequently established or acquired) to purchase common shares at designated intervals at a discount through their accumulated payroll deductions or other contributions.

The Purchase Plan is intended to qualify as an employee share purchase plan under Section 423 of the Internal Revenue Code of 1986, as amended (“Section 423”). Favorable tax treatment is available for United States tax residents participating in a Section 423 plan. The Purchase Plan also authorizes the grant of rights to purchase shares that do not qualify under Section 423 pursuant to offerings implemented by the plan administrator to achieve tax, securities law or other compliance requirements and objectives in particular locations outside of the United States.

The Plan Purchase will serve as the successor to the Company’s Employee Share Purchase Plan (the “Predecessor Purchase Plan”) which is scheduled to terminate on February 9, 2020. As of August 31, 2018, 128,980 shares were issuable under outstanding offerings under the Predecessor Purchase Plan and no shares would be available for future offerings following such issuances. We are proposing the adoption of the Purchase Plan at this time because the remaining reserve is not sufficient to make additional offerings under the Predecessor Purchase Plan until its termination. If the Company’s shareholders approve this proposal, no additional offerings will be made under the Predecessor Purchase Plan after the Purchase Plan Effective Date. All outstanding offerings under the Predecessor Purchase Plan, however, shall continue in effect in accordance with their terms, consistent with the Predecessor Purchase Plan. Approval of this proposal will allow us to continue to provide an incentive to attract, retain and reward our eligible employees and the eligible employees of our participating parent and subsidiaries. The Purchase Plan is an important component of the overall benefits we offer our employees.

The following is a summary of the principal features of the new Purchase Plan. The summary, however, is not intended to be a complete description of the Purchase Plan and is qualified in its entirety by reference to the complete text of the Purchase Plan, filed with this Proxy Statement as Appendix B.

Administration

The Purchase Plan will be administered by the Compensation Committee of the Board of Directors. Such committee will as plan administrator have full authority to adopt administrative rules and procedures and to interpret the provisions of the Purchase Plan.

Securities Subject to the Purchase Plan

The number of common shares reserved for issuance under the Purchase Plan will be 1,430,000 shares, subject to adjustments described below. The common shares issuable under the Purchase Plan may be made available from our authorized but unissued common shares or from common shares repurchased by the Company, including shares repurchased on the open market.

In the event any change is made to the common shares by reason of any share split, share dividend, recapitalization, combination of shares, exchange of shares, spin-off transaction, extraordinary distribution (whether in cash, securities or other property) or other change affecting the outstanding common shares as a class without the our receipt of consideration, or should the value of the outstanding common shares be substantially reduced as a result of a spin-off transaction or an extraordinary dividend or distribution, then equitable adjustments shall be made to (i) the maximum number and class of securities issuable under the Purchase Plan, (ii) the maximum number and class of securities purchasable per participant on any one Purchase Date, (iii) the maximum number and class of securities purchasable in total by all participants on any one Purchase Date and (iv) the number and class of securities and the price per share in effect under each outstanding purchase right. The adjustments will be made in such manner as the plan administrator deems appropriate.

26

Offering Periods and Purchase Rights

Common shares will be offered for purchase under the Purchase Plan through a series of successive offering periods which will be of such duration (not to exceed 27 months) as determined by the plan administrator. Unless otherwise specified by the plan administrator prior to the start of the applicable offering period, offering periods will commence on May 15 and November 15 (or if such dates are not trading days, then the first trading day immediately following such dates) and will be of a duration of approximately twenty-four (24) months. The initial offering period under the Purchase Plan is expected to commence on November 15, 2018.

Each offering period will consist of one or more successive purchase intervals as determined by the plan administrator prior to the commencement of such offering period. Until such time as otherwise determined by the plan administrator, each offering period will be comprised of four (4) purchase intervals; purchase intervals will generally run from May 15 to November 14 each year and from November 15 each year to May 14 in the next year.

Should the fair market value per common share on any purchase date within an offering period be less than the fair market value per common share on the start date of that offering period, then the individuals participating in that offering period will, immediately after the purchase of our common share on their behalf on such purchase date, be transferred from that offering period and automatically enrolled in the new offering period commencing on the next business day following such purchase date, provided the fair market value per share on the start date of that new offering period is lower than the fair market value per common share on the start date of the offering period in which they were currently enrolled.

On the first day of each offering period, each participant will be granted a purchase right to acquire our common shares on the last day of that offering period, subject to certain limitations described below.

Eligibility and Participation

All employees of the Company or any participating parent or subsidiary corporation (whether any such corporation is currently a parent or subsidiary or subsequently acquired or is subsequently established at any time during the term of the Purchase Plan) will be eligible to participate in any offering period implemented under the Purchase Plan. The Purchase Plan currently provides that an employee of the Company or a participating parent or subsidiary who is employed on a basis under which he or she is regularly expected to work for more than twenty hours per week for more than five months per calendar year is eligible to participate in an offering period under the Purchase Plan. However, the plan administrator may waive one or both of the service requirements.

To participate in a particular offering period, an eligible employee must complete and file the requisite enrollment forms during the enrollment period for that offering period. However, any individual enrolled in any offering period outstanding under the Predecessor Purchase Plan on the Purchase Plan Effective Date will automatically, following the completion of that offering period, be enrolled in the Purchase Plan upon the same terms and conditions in effect for that offering period, including the authorized rate of payroll deduction, on the start date of the first offering period under the Purchase Plan thereafter that incorporates those same terms and conditions.

As of August 31, 2018, approximately 3,521 employees, including 3 executive officers, would have been eligible to participate in the Purchase Plan had it been in effect on such date.

Contributions and Stock Purchases

Each participant may authorize contributions in any multiple of one percent up to a maximum of fifteen percent (or such other limit established by the plan administrator) of the base salary or cash earnings (as established by the plan administrator for an offering period) paid to the participant for the offering period.

Participants contribute to the Purchase Plan through payroll deductions or, if permitted, through other means specified by the plan administrator. Currently, contributions are expected to be permitted only through payroll deductions.

The accumulated contributions will automatically be applied to the acquisition of common shares on each purchase date (generally May 14 or November 14 each year). Accordingly, on each purchase date, each participant’s contributions accumulated for the offering period ending on that purchase date will automatically be applied to the purchase of whole and fractional shares of common stock at the purchase price in effect for that purchase date. The first purchase under the Purchase Plan is expected to occur on May 14, 2019.

27

Purchase Price

The purchase price of the common shares acquired on each purchase date will not be less than eighty-five percent of the lower of the fair market value per share of the common shares on the first day of the offering period or the fair market value on the last day of that offering period.

The fair market value per our common share on any particular date under the Purchase Plan will be deemed to be equal to the closing price per share on such date on the NASDAQ Global Select Market (or if there is no closing price on such date, then the closing price per share on the last preceding date for which such quotation exists). On August 31, 2018, the fair market value of our common share determined on such basis was $14.21 per share.

Special Limitations

The Purchase Plan imposes certain limitations upon a participant’s rights to acquire common shares, including the following limitations:

• Purchase rights granted to a participant may not permit such individual to purchase more than $25,000 worth of our common shares (valued at the time each purchase right is granted) for each calendar year those purchase rights are outstanding at any time.

• Purchase rights may not be granted to any individual if such individual would, immediately after the grant, own or hold outstanding options or other rights to purchase, shares possessing five percent (5%) or more of the total combined voting power or value of all classes of our outstanding shares or the outstanding shares of any of the company’s affiliates.

• No participant may purchase more than 875 common shares on any purchase date during any offering period and no more than 200,000 common shares may be purchased by all participants on any purchase date during any offering period (in each case subject to adjustment as indicated above).

The plan administrator will have the discretionary authority to increase or decrease the per participant and aggregate limitation as of the start date of any new offering period under the Purchase Plan, with the new limit to be in effect for that offering period.

Termination of Purchase Right

The participant may withdraw from the Purchase Plan at any time prior to the next scheduled purchase date, and his or her accumulated contributions for the offering period in which that withdrawal occurs will at the participant’s election, either be applied to the purchase of shares on the next scheduled purchase date or be refunded immediately.

The participant’s purchase right will immediately terminate upon his or her cessation of employment or loss of eligible employee status. Any contributions which the participant may have made for the offering period in which such cessation of employment or loss of eligibility occurs will be refunded.

Shareholder Rights

No participant will have any shareholder rights with respect to the shares covered by his or her purchase rights until the shares are actually purchased on the participant’s behalf and the participant has become a holder of record of the purchased shares. No adjustment will be made for dividends, distributions or other rights for which the record date is prior to the date of such purchase.

Assignability

No purchase rights will be assignable or transferable by the participant, and the options will be exercisable only by the participant.

Change of Control

Should we be acquired by merger, or should there occur a sale of substantially all of our assets or of securities possessing more than fifty percent of the total combined voting power of our outstanding securities, or should there occur certain changes in the majority of our board of directors,all outstanding purchase rights will automatically be exercised immediately prior to the

28

effective date of such change in control. The purchase price for any abbreviated offering period will be based on the purchase price formula in effect for the offering period in which such change in control occurs.

The limitation on the maximum number of shares purchasable by each participant (but not the limitation on all participants in the aggregate) on any one purchase date will be applicable to any purchase date attributable to such change in control.

Share Pro-Ration

Should the total number of common shares to be purchased pursuant to outstanding purchase rights on any particular date exceed the number of shares then available for issuance under the Purchase Plan, then the plan administrator will make a pro-rata allocation of the available shares on a uniform and nondiscriminatory basis, and the contributions of each participant, to the extent in excess of the aggregate purchase price payable for the common shares pro-rated to such individual, will be refunded.

Amendment and Termination

The Purchase Plan will terminate upon the earliest to occur of (i) the last business day in November 14, 2028, (ii) the date on which all shares available for issuance thereunder are sold pursuant to exercised purchase rights or (iii) the date on which all purchase rights are exercised in connection with a change in control or ownership, unless terminated earlier by the plan administrator.

The plan administrator may alter or amend the Purchase Plan at any time. In no event may the plan administrator effect either of the following amendments or revisions to the Purchase Plan without the approval of the shareholders: (i) increase the number of shares of the common stock issuable under the Purchase Plan, except for permissible adjustments in the event of certain changes in the company’s capitalization or (ii) modify the class of corporations that may be designated for participation in the Purchase Plan.

New Plan Benefits

The Purchase Plan will not become effective unless it is approved by the shareholders at the 2018 annual meeting and no purchase rights have been granted under the Purchase Plan.

Summary of Federal Income Tax Consequences

The Purchase Plan is intended to be an “employee stock purchase plan” within the meaning of Section 423. Under a plan which so qualifies, no taxable income will be recognized by a participant, and no deductions will be allowable to the company, upon either the grant or the exercise of the purchase rights. Taxable income will not be recognized until there is a sale or other disposition of the shares acquired under the Purchase Plan or in the event the participant should die while still owning the purchased shares.

If the participant sells or otherwise disposes of the purchased shares within two years after the start date of the offering period in which such shares were acquired or within one year after the purchase date of those shares, then the participant will recognize ordinary income in the year of sale or disposition equal to the amount by which the fair market value of the shares on the purchase date exceeded the purchase price paid for those shares, and the company will be entitled to an income tax deduction, for the taxable year in which such sale or disposition occurs, equal in amount to such excess.

If the participant sells or disposes of the purchased shares more than two years after the start date of the offering period in which the shares were acquired and more than one year after the purchase date of those shares, then the participant will recognize ordinary income in the year of sale or disposition equal to the lesser of (i) the amount by which the fair market value of the shares on the sale or disposition date exceeded the purchase price paid for those shares or (ii)  fifteen percent (15%) of the fair market value of the shares on the start date of that offering period, and any additional gain upon the disposition will be taxed as a long-term capital gain. The company will not be entitled to an income tax deduction with respect to such sale or disposition.

If the participant still owns the purchased shares at the time of death, then the participant will recognize ordinary income at such time equal to the lesser of (i) the amount by which the fair market value of the shares on the date of death exceeds the purchase price or (ii) fifteen percent (15%) of the fair market value of the shares on the start date of the offering period in which those shares were acquired.

Foreign Taxation

29

The income tax consequences to participants in the Purchase Plan who are resident outside the U.S. will vary by country. Generally, those participants will be subject to taxation at the time the shares are purchased.

Summary of Accounting Treatment

Pursuant to Accounting Standards Codification Topic 718 of the Financial Accounting Standards Board, the grant date fair value of each option granted will be charged as a direct compensation expense to the company’s reported earnings over the offering period to which that option pertains.

Vote Required

Provided a quorum is present, the affirmative vote of holders of a majority of the votes cast in person or represented by proxy and entitled to vote at the Annual Meeting will be required to approve the adoption of the Purchase Plan. Should such shareholder approval not be obtained, then the Purchase Plan will not become effective.

Recommendation of Board of Directors

The Board of Directors recommends that the shareholders vote FOR the approval of the implementation of the Purchase Plan. The Board of Directors believes that it is in the best interests of the company to provide our employees with the opportunity to acquire an ownership interest in the company through their participation in the Purchase Plan and thereby encourage them to remain in the company’s employ and more closely align their interests with those of the shareholders.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

The following is a discussion and analysis of the compensation arrangements that were in effect for the fiscal year ended June 30, 2018 for the named executive officers identified in the Summary Compensation Table that follows. This discussion should be read together with that table and the other compensation tables and related disclosures that follow.

Fiscal Year 2018 Business and Financial Highlights

During the fiscal year ended June 30, 2018, the Company achieved several important financial, business and operational milestones, including the following:

• A record-breaking annual revenue of $422 million, which represented a 10% growth in annual revenue from the prior fiscal year;

• A non-GAAP gross margin expansion of 270 basis points, and non-GAAP earnings per share increase of 37%, as compared to a year ago;

• Developed 200 new products and continued the diversification strategy by developing new silicon and packaging platforms to expand serviceable available market;

• The core MOSFET portfolio expanded significantly across a full range of voltage applications, and made significant progress to generating sales in the consumer, communications and industrial markets as well as power IC for the next generation computing applications.

• Chongqing joint venture reached several major milestones, including the substantial completion of the assembly and testing facilities and 12-inch wafer fab facilities, and secured 400 million RMB (equivalent of $60 million based on the currency exchange rate as of June 30, 2018) of capital from third parties to fund the construction of the facilities;

• License agreement with STMicroelectronics International N.V., which allowed the Company to develop and market digital power multi-phase controller products and enter into new markets, primarily in server and telecommunications sectors;

• Secured $31 million of term loans to fund capital expenditure of the Oregon fab and other operational expenses; and

• Approval of a new share repurchase program of up to $30 million.

Compensation Philosophy and Objectives

Our philosophy is to provide our named executive officers with compensation that will motivate and retain them, provide them with meaningful incentives to achieve and exceed short-term and long-term corporate objectives set by our Compensation Committee, and align their long-term interests with those of our shareholders.

Based on this philosophy, the compensation programs for our named executive officers are designed to achieve the following primary objectives:

• establish a compensation structure that is competitive enough to attract, retain and motivate outstanding executive talent;

• ensure that any cash incentive compensation programs for our named executive officers are aligned with our corporate strategies and business objectives by tying the potential payouts under such programs to the achievement of key strategic, financial and operational goals; and

• utilize long-term equity awards to align interests between our named executive officers and shareholders.

Executive Compensation Practices

31

We strive to maintain sound governance standards and compensation practices and have incorporated many best practices into our 2018 compensation programs, including the following: 

WHAT WE DO
Ÿ   Use performance-based annual and long-term incentives to align our executive pay with performance	ŸMaintain a clawback policy
Ÿ   Make payouts under our bonus plan only if threshold Company performance is met	Ÿ   Set challenging performance objectives for our performance-based awards and annual bonus
Ÿ   Use multi-year vesting periods for our equity awards	Ÿ   Hold an annual “say-on-pay” advisory vote
Ÿ   Include caps on individual payouts in short- and long-term incentive plans	Ÿ   Maintain an independent compensation committee
ŸMaintain a share ownership policy for our executive officers and Board members

WHAT WE DON’T DO
X   Offer contracts with multi-year guaranteed salary or bonus increases	X  Offer guaranteed retirement benefits or non-qualified deferred compensation plans
X   Provide tax gross-ups	X   Provide excessive perquisites
X   Time the release of material non-public information to affect the value of executive compensation

Impact of 2017 Say-on-Pay Vote

Each year, our Compensation Committee considers the outcome of the annual shareholder advisory vote when making decisions relating to the compensation of our named executive officers and an executive compensation programs and policies. We held our last vote in 2017 and approximately 98.5% of the total votes cast on such proposal were in favor of the compensation of the named executive officers, as that compensation was disclosed in the Compensation Discussion and Analysis and the various compensation tables and narrative that appeared in the Company’s proxy statement dated October 3, 2017. Based on that high level of shareholder approval, the Compensation Committee decided not to make any material changes to the Company’s compensation philosophies, policies and practices for the fiscal year 2018 compensation of the named executive officers.

The Compensation Committee will continue to take into account future shareholder advisory votes on executive compensation and other relevant market developments affecting executive officer compensation in order to determine whether any subsequent changes to the Company’s executive compensation programs and policies would be warranted to reflect any shareholder concerns reflected in those advisory votes or to address market developments.

Compensation Decision-Making Process

The Compensation Committee meets on a regular schedule throughout the year to manage our compensation programs.  The Compensation Committee reviews the principle components of compensation for our executive officers on an annual basis, typically at its first meeting in the calendar year.  As part of that review process, the Compensation Committee reviews and may adjust the base salaries of our named executive officers.  The Compensation Committee also establishes the cash bonus plan for the year and determines the cash bonuses payable to our named executive officers for the preceding year based on achievement of the pre-specified performance goals for that prior year and grants equity awards to our named executive officers to ensure their interests are aligned with shareholders and for retention.

In setting executive compensation, the Compensation Committee takes into account a number of factors, including the nature and scope of the named executive officer's responsibilities, his or her individual performance level and contribution to the achievement of our corporate objectives, the experience level of the executive, the recommendations of our Chief Executive Officer for each individual's compensation package (other than his own) and the compensation trends in the industry.

Role of Compensation Consultant. The Compensation Committee retained Compensia to advise the committee on the compensation for executive officers and other senior officers for fiscal year 2018. In November 2017, Compensia proposed and the Compensation Committee accepted a revised peer group of companies to remove certain companies that had been acquired; the peer group was used primarily in connection with a review of competitive compensation for our chief executive officer and chief financial officer. The peer group for fiscal year 2018 was comprised of the following companies:

32

Diodes	Lattice Semiconductor	NeoPhotonics
DSP Group	M/A-COM Technology Solution	Power Integrations
Inphi	Maxlinear	Semtech
Integrated Device Tech	Monolithic Power Systems	Sigma Designs
IXYS

In December 2016 and January 2018, Compensia provided the Compensation Committee with compensation data based on the peer group companies (for our chief executive officer and our chief financial officer) and Radford survey data for companies with revenues in the range of $200 million to $500 million (for all officers), and analysis with respect to market positioning and the cost to bring the compensation of our executive officers to various levels of market.

Our Compensation Committee reviewed and considered the 2016 report and analysis in connection with establishing base salary and bonus potential for fiscal year 2018 and the 2018 report and analysis in connection with establishing equity awards for fiscal year 2018 but in both cases relied on its own judgment and experience in establishing and adjusting executive compensation for fiscal year 2018.

For a discussion of the specific responsibilities of our Compensation Committee, see "Board of Directors and Committees of the Board - Committees of the Board of Directors - Compensation Committee” above.

Role of Management.  Our Chief Executive Officer, with input from our Vice President of Human Resources, provides our Compensation Committee with his recommendations as to the base salary, cash bonus potential and long-term equity incentive award for each of our named executive officers other than himself based on that officer's level of responsibility, individual performance and contribution to the attainment of our strategic corporate objectives and market data. Our Compensation Committee takes the Chief Executive Officer's recommendations into consideration in setting named executive officer compensation, but retains complete discretionary authority to make all compensation-related decisions for our named executive officers.  Our Compensation Committee makes its compensation decisions with respect to the Chief Executive Officer on the basis of relevant market data furnished by Compensia and its subjective assessment of his individual performance and contributions to our overall corporate performance. Any decisions regarding our Chief Executive Officer's compensation are made without him present.

Compensation Structure

Elements of Compensation

We utilize three main components in structuring compensation programs for our named executive officers:

• Base salary, which is the only fixed compensation element in our executive compensation program and is primarily used to recruit and retain executive talent and provide an element of economic security from year to year;

• Performance-based cash bonuses that are primarily designed to reward achievement of financial and operational goals; and

• Equity incentive awards designed to ensure long-term retention of our executive talent and align their interests with those of our shareholders.

We view each component of compensation as related but distinct. It is the practice of our Compensation Committee to allocate a substantial portion of each named executive officer's total compensation to performance and long-term incentive compensation as a result of the philosophy described above. There is no pre-established policy for the allocation of compensation between cash and non-cash components or between short-term and long-term components, and there are no pre-established ratios between the compensation of our Chief Executive Officer and that of the other named executive officers. Instead, our Compensation Committee determines the compensation of each named executive officer based on its review of the market data provided by Compensia, its subjective analysis of that individual's performance and contribution to our financial performance and the other factors identified in the Compensation Decision-Making Process section above to determine the appropriate level and balance of total compensation.  We believe that this approach allows us to tailor compensation for each named executive officer to attract, retain and motivate that executive officer within the parameters of our compensation philosophy.

33

Base Salaries

Base salaries are set at levels that are intended to recognize the experience, skills, knowledge and responsibilities required of all our named executive officers.  Each named executive officer's base salary level is typically reviewed on an annual basis and adjustments may be made to the individual's base salary on the basis of his or her level of performance, the overall performance of the Company and the various compensation trends in our industry.

In March 2017, the Compensation Committee approved salary adjustments of 3% over the fiscal year 2017 salaries for each named executive officer (except that Mr. Liang’s base salary was increased by 5.8% in an effort to bring his salary closer to market). The base salaries for the named executive officers effective July 1, 2017 were as follows:

Named Executive Officer	Annual Base Salary
Mike F. Chang	$	440,524
Yifan Liang	$	312,000
Yueh-Se Ho	$	301,411
Daniel Kuang Ming Chang	$	275,834

Performance-Based Bonuses

Our named executive officers are eligible to receive a bonus under our annual Executive Incentive Plan.  Each year, our Compensation Committee establishes the performance objectives to be attained and the target bonuses payable based on the level of attainment of the specified goals.  Since 2016, the bonus has been determined on a calendar year basis with performance goals based on the Company’s annual operating plan which is established on a calendar year basis.

In March 2017, the Compensation Committee established the Executive Incentive Plan for calendar year 2017. The aggregate amount of the award was to be determined based on the level of attainment of a range of GAAP operating income and a multiplier based on revenue for the year. The operating income goal ranged from $7.3 million at threshold bonus, $10.2 million at target bonus and $14.8 million at maximum bonus; on a non-GAAP basis comparable to the performance goal for the Executive Incentive Plan for calendar year 2016, excluding share-based compensation charge, the non-GAAP operating income would range from $17.1 million at threshold bonus, $20.0 million at targeted bonus, and $24.6 million at maximum bonus).  The revenue multiplier ranged from 0.8 at threshold revenue of $378.3 million, 1.0 at target revenue of $392 million and 1.1 at maximum revenue of $402 million. The specified minimum amount of each of the operating income and revenue goals had to be achieved before payment of an award under the plan was earned.

The actual aggregate amount of the award earned by a named executive officer for the year ranged from $0 to the maximum amount established for that officer (as a percentage of base salary at the time of payment as specified below) depending on the level of attainment of the performance goals. Up to 50% of the amount of any earned bonus award was payable in our common shares as determined by the Compensation Committee.

The threshold, target and maximum bonuses payable to each of our named executive officers for calendar year 2017 based on level of attainment of the performance goals were as follows:

	Threshold Bonus	Target Bonus	Maximum Bonus
Named Executive Officer	% of Base Salary	% of Base Salary	% of Base Salary
Mike F. Chang	20 %	100 %	220 %
Yifan Liang	12 %	60 %	132 %
Yueh-Se Ho	12 %	60%	132 %
Daniel Kuang Ming Chang	12 %	60%	132 %

Based on calendar year 2017, GAAP operating income of $14.4 million ($24.2 million on a non-GAAP basis) and revenue of $400 million (resulting in a multiplier of 1.08), the Compensation Committee approved bonuses for calendar year 2017 on March 12, 2018 at 204.4% of target for our Chief Executive Officer and 206.5% of target for the other officers as set forth below. 50% of the bonus was paid in cash and the remaining 50% was paid in common shares based on the $16.73 closing price per share on March 12, 2018.

34

Named Executive Officer	Target Bonus ($)	Actual Bonus ($)	Bonus Paid in Cash ($) *	Bonus Paid in Shares (# of shares) *
Mike F. Chang	440,524	900,617	450,312	26,916
Yifan Liang	187,200	386,495	193,247	11,551
Yueh-Se Ho	180,847	373,378	186,688	11,159
Daniel Kuang Ming Chang	165,500	341,693	170,846	10,212

Equity Compensation Plans

Our equity award program is the primary vehicle for offering long-term incentives to our named executive officers and providing an inducement for long-term retention. Equity compensation represents a significant component of the total compensation package we provide to each of our named executive officers.  We believe this weighting is appropriate because it aligns the interests of our named executive officers with those of our shareholders and focuses their attention on the creation of shareholder value in the form of stock price appreciation. The Compensation Committee may use both stock options and restricted stock units as part of the Company’s long-term incentive program for named executive officers although in recent years, only restricted stock units have been awarded to the named executive officers. The Company believes that there are several advantages of using restricted stock units including ongoing concerns over the dilutive effect of option grants on the Company’s outstanding shares, the Company’s desire to have a more direct correlation between the compensation expense it must record for financial accounting purposes and the actual value delivered to executive officers, and the fact that the incentive and retention value of a restricted stock unit award is less affected by market volatility than stock options. Starting with fiscal year 2017, the Compensation Committee introduced performance-based restricted stock units that vest based on the level of attainment of Company performance goals.  The Compensation Committee believes that including performance-based restricted stock units as part of our equity-based compensation program strengthens focus on the Company’s financial performance and shareholder value creation.

Our Compensation Committee reviews our equity compensation program annually and may, at its discretion, grant additional equity awards to existing named executive officers consistent with our named executive officer compensation objectives.  In determining the size of those additional grants, our Compensation Committee typically takes into account the recommendations of our Chief Executive Officer, data provided by (and recommendation of) Compensia and its own subjective assessment of the named executive officer’s performance and the retention value of his or her existing equity awards.

Any stock options granted to our employees, including executive officers, and to our directors are granted with a per share exercise price equal to the closing price of our common shares on the date of grant as reported on the NASDAQ Global Select Market.

A subcommittee comprised of our Chief Executive Officer and Chief Financial Officer is authorized to grant options and restricted stock unit awards to newly-hired employees, other than executive officers, within prescribed limits specified by position and location of the employee pursuant to authority delegated to the subcommittee by the Board of Directors.  These grants are generally made on the 15th day of each month.

March 2018 Grants: On March 12, 2018, the Compensation Committee authorized, effective as of March 15, 2018, the grant of restricted stock units to each of our named executive officers for the number of our common shares allocated between time-based restricted stock units and performance-based restricted stock units as indicated below. The Compensation Committee increased the performance-based component of the awards (relative to the 2017 awards) to be in-line with market.

35

Named Executive Officer	Time-Based Restricted Stock Units (Shares)	Performance -Based Restricted Stock Unit  (Target Shares)
Mike F. Chang	50,000	90,000
Yifan Liang	13,000	22,000
Yueh-Se Ho	13,000	22,000
Daniel Kuang Ming Chang	8,000	13,000

Each time-based restricted stock unit entitles the holder to receive one common share following vesting. Each such award will vest with respect to 25% of the units annually upon the participant’s completion of each year of service over the four-year period measured from March 15, 2018. Each performance-based restricted stock unit award will vest based on the level of attainment of specified Non-GAAP earnings per share and revenue goals over the period January 1, 2018 to December 31, 2018 and the participant’s continued service over a four-year period measured from March 15, 2018.

For more information concerning the restricted stock unit awards we granted to our named executive officers in 2018, please see “Grants of Plan-Based Awards 2018” below.

March 2017 Grants: On March 1, 2017, the Compensation Committee authorized, effective as of March 15, 2017, the grant of restricted stock units to each of our named executive officers for the number of our common shares allocated between time-based restricted stock units and performance-based restricted stock units as indicated below.

Named Executive Officer	Time-Based Restricted Stock Units (Shares)	Performance -Based Restricted Stock Unit  (Target Shares)
Mike F. Chang	70,000	63,000
Yifan Liang	25,000	10,000
Yueh-Se Ho	12,500	12,500
Daniel Kuang Ming Chang	12,000	10,000

Each time-based restricted stock unit entitles the holder to receive one common share following vesting. Each such award will vest with respect to 25% of the units annually upon the participant’s completion of each year of service over the four-year period measured from March 15, 2017 over a four-year period. Accordingly, the time-based awards vested with respect to 25% of the units on March 15, 2018.

Each performance-based restricted stock unit award was to vest based on the level of attainment of specified earnings per share and revenue goals over the period January 1, 2017 to December 31, 2017 and the participant’s continued service over a four-year period measured from March 15, 2017. The applicable performance conditions were (i) GAAP earnings per share of at least $0.28 per share as the qualifying criterion which if not met would let to the award vesting at 0% (regardless of level of attainment of revenues) and (ii) increase in the Company’s revenue over the threshold revenue of $382 million up to a maximum revenue of $402 million with a range of payout based on actual increase in revenue and earnings per share. Based on revenue for the performance period of $400 million and GAAP earnings per share of $0.77 per share, the Compensation Committee determined that 90% of the target number of shares subject to each participant’s 2017 performance-based restricted stock unit award will vest subject to the service vesting requirement. Each such award will vest with respect to 25% of such performance-qualified units annually upon completion of each year of service over the four-year period measured from March 15, 2017. Accordingly, 25% of the performance-qualified units vested on March 15, 2018.

Termination and Change in Control Benefits

We have entered into an employment agreement with our Chief Executive Officer which sets forth certain terms and conditions governing his period of continued employment with us including certain benefits to which he would become entitled were his employment to be terminated involuntarily.  In addition, we have entered into retention agreements with each of our named executive officers pursuant to which such officers are entitled to certain severance benefits upon an involuntary

36

termination of employment.  The employment agreement and retention agreements are summarized below in the section of this proxy entitled “Agreements Regarding Employment, Change in Control and Termination of Employment”.

Pursuant to his employment agreement, Dr. Mike Chang's severance will depend upon whether the involuntary termination occurs in connection with a change in control.  If his employment is terminated by the Company (without cause) or he resigns for good reason within 12 months following a change in control, Dr. Mike Chang will be entitled to (i) continued payment of base salary and health care coverage for a period of 24 months and (ii) full vesting acceleration of his outstanding equity awards.  In the case of such involuntary termination other than during the 12 months following a change in control, he will be entitled to continued payment of base salary and health care coverage for a period of 12 months and no accelerated vesting of his outstanding unvested equity awards.

Under the retention agreements, the named executive officer's severance will depend upon whether the involuntary termination occurs in connection with a change in control.  If such officer's employment is terminated by the Company (without cause) or he resigns for good reason within 12 months following a change in control, he will be entitled to (i) continued payment of base salary and health care coverage for a period of 6 months and (ii) vesting acceleration of his outstanding equity awards with respect to that number of shares in which he would have vested had he remained employed for an additional 12 months.  In the case of such involuntary termination other than during the 12 months following a change in control, he will be entitled to continued payment of base salary and health care coverage for a period of 6 months and no accelerated vesting of his outstanding unvested equity awards.

The severance benefits that we have provided in connection with a change in control situation are designed to serve two primary purposes: (i) encourage our named executive officers to remain our employee in the event of an actual or potential change in control transaction and (ii) align the interests of the named executive officers with those of the shareholders by enabling the named executive officers to consider acquisition transactions that are in the best interests of the shareholders and provide opportunities for the creation of substantial shareholder value without undue concern over whether those transactions may jeopardize their employment or their existing compensation arrangements.  Our Compensation Committee also believes that the severance benefits payable on an involuntary termination in the absence of a change in ownership serve as an important recruitment and retention tool that allows us to remain competitive in attracting and retaining executive talent.

Pursuant to the terms of our equity plans, outstanding options and time-based restricted stock units awards held by our named executive officers and our other employees will accelerate upon a change in control unless those options or awards are assumed or otherwise replaced by the acquiring entity. The performance-based restricted stock units awards will convert into the right to receive 50% of the target number of shares or the actual number of shares based on level of attainment of performance goals depending on when the change in control occurs and will be paid out at the time of accelerated upon the change in control unless those awards are assumed or otherwise replaced by the acquiring entity. The Compensation Committee believes that accelerated vesting under such a limited circumstance is appropriate because it protects a significant component of the named executive officer's total compensation in the event those options and awards would otherwise terminate in the acquisition and allows our named executive officers to remain focused on the Company's business without undue concern over this significant component of their compensation package should the Company become an acquisition target in a transaction in which the outstanding equity awards would not be assumed or replaced.

Our severance and change of control provisions for the named executive officers are discussed in more detail in "Potential Payments upon Termination of Employment" below.

Benefits and Other Compensation

We maintain broad-based employee benefit plans, which are provided to all eligible employees, including our named executive officers.  These plans provide group medical and dental coverage, life insurance, disability insurance, flexible spending accounts and a 401(k) savings program for our employees based in the United States.  We also offer bonuses for patented inventions, authoring technical articles and making technical presentations at major symposiums; our named executive officers are eligible to receive bonuses under these programs on the same basis as our other employees.

We believe these benefits are consistent with the benefits offered by companies with which we compete for employees and are necessary to attract and retain qualified employees.

Perquisites

We believe that cash and equity compensation are the key components needed to attract and retain our executive management.  As a result, we do not provide any substantial perquisites to our named executive officers.

Stock Ownership Guidelines

During fiscal year 2018, our Board of Directors adopted stock ownership guidelines for our executive officers and the non-employee members of our Board of Directors. Under these guidelines, each executive officer is required to own shares with a value equal to a specified multiple of his or her annual base salary and each non-employee member of our Board of Directors is required to own shares with a value equal to a specified multiple of his or her annual cash retainer.  As adopted, these base salary and annual retainer multiples are as follows:

Position	Specified Multiple
Chief Executive Officer	Three times base salary
Other Executive Officer	One times base salary
Board Member	Three times annual retainer

Shares that count towards satisfaction of the guidelines include shares beneficially owned by the individual or immediate family members, shares held in trust for the benefit of the individual or immediate family members and deferred shares subject to vested restricted stock units or performance share units and other vested equity awards. Unvested restricted stock units, unvested performance units or restricted shares, and unexercised stock options do not count towards satisfaction of the guidelines.

Our executive officers and the non-employee members of our Board of Directors are required to meet these ownership requirements within five years of the later of (1) May 3, 2018 (the date of adoption of the guidelines) or (2) becoming an executive officer or non-employee member of our Board of Directors, as applicable. The Compensation Committee believes that this stock ownership aligns the financial interests of our executive officers with those of our shareholders.

Clawback Policy

During fiscal year 2018, the Compensation Committee adopted the Executive Compensation Clawback Policy. The policy applies to all equity and/or cash incentive plans, and allows the Company to recover incentive compensation from current or former executive officers in the event that a financial statement used as the basis of calculating awards under an incentive plan is required to be restated and the covered individual engaged in intentional misconduct which materially contributed to the need for such restatement. The clawback will apply to incentive compensation that was awarded, vested and/or paid during the three-year period prior to the date the Company is required to prepare the restatement with the amount of the clawback to be calculated as the portion of incentive compensation which exceeds what would have been paid with the restatement.

Risk Assessment

The Compensation Committee believes the various components of the total compensation package of our named executive officers, as discussed above, are appropriately balanced so as to avoid any excessive risk taking by such individuals. Factors considered by the Compensation Committee include:

• Our executive compensation program reflects an appropriate mix of compensation elements and balances annual and long-term performance objectives and cash and equity compensation.

• A significant portion of our executive compensation program is performance-based and aligned with the long-term interests of our shareholders.

• We use a combination of performance metrics that are consistent with our business objectives and correlate to long-term shareholder value.

• Our performance goals are set at levels that we believe are reasonable in light of past performance and market conditions.

• Long-term equity awards tied to the market price of our common shares represent a significant component of executive officer compensation and promote a commonality of interest between the executive officers and our shareholders in increasing shareholder value.  

• The use of restricted stock units which provide varying levels of compensation as the market price of the Company’s common shares fluctuates over time mitigates the potential risk that stock options pose in encouraging risk taking in

38

the short term and are less likely to contribute to excessive risk taking.  Furthermore, our equity awards are comprised of time-based and performance-based awards that vest, if at all, over a period of years, and that vesting element encourages the award recipients to focus on sustaining our long-term performance.

• Under the annual executive incentive bonus program, an individual target bonus amount is established for each named executive officer at each level of potential goal attainment.  Accordingly, at all levels of performance goal attainment, there are limits in place for the potential bonus payout.  In addition, a maximum bonus amount is established for each participant such that no participant may earn more than a fixed percentage of his base salary.

• Our share ownership guidelines require our named executive officers to hold a significant level of our common shares so that each executive has personal wealth tied to the long-term success of the company and is thereby aligned with shareholders’ interest.

Accordingly, our overall compensation structure is not overly-weighted toward short-term incentives, and the Compensation Committee has taken what it believes are reasonable steps to protect against the potential of disproportionately large short-term incentives that might encourage excessive risk taking.

Internal Revenue Code Section 162(m)

For years prior to 2018, Section 162(m) of the Internal Revenue Code generally disallowed a federal income tax deduction for publicly-traded companies such as the Company for compensation paid to the Chief Executive Officer and the three other highest paid executive officers (other than the principal financial officer) to the extent that such compensation exceeds $1 million per officer in any one year and does not otherwise qualify as performance-based compensation. The Predecessor Plan is structured so that compensation deemed paid to an executive officer in connection with the exercise of options should qualify as performance-based compensation that is not subject to the $1 million limitation. However, restricted share units and bonus awards will not qualify as such performance-based compensation. In addition, “grandfather” provisions may apply to certain compensation arrangements that were entered into by a company before it was publicly held and certain compensation arrangements and awards that are made during a specified period following the date the company becomes publicly held.

The exemption for qualified performance-based compensation has been repealed and the class of affected executives has been expanded effective for taxable years beginning after December 31, 2017 such that compensation paid to our covered executive officers in excess of $1 million will not be deductible unless it qualified for transition relief applicable to certain arrangements in place as of November 2, 2017. Because of the uncertainties as to the scope and application of the transition relief, no assurances can be given that compensation intended to satisfy the requirements for exemption under Section 162(m) will in fact be fully deductible.

Our Compensation Committee may continue to provide one or more named executive officers with the opportunity to earn incentive compensation, whether through cash incentive programs or equity incentive programs, which may be in excess of the amount deductible by reason of Section 162(m) or other provisions of the Internal Revenue Code.

Summary Compensation Table

The following table provides information regarding the compensation paid during our fiscal year ended June 30, 2018 to our principal executive officer, the individual who served as our principal financial officers and our two other executive officers with aggregate compensation in excess of $100,000.  We refer to these individuals as our named executive officers.

(1	)	The amounts shown do not reflect compensation actually received by the named executive officer. Instead the dollar value shown represents the grant date fair value of the award determined in accordance with FASB ASC Topic 718 without taking into account any estimated forfeitures related to service vesting conditions. For assumptions used in determining such grant date fair value, see Note 8 to the consolidated financial statements contained in our Annual Report on Form 10-K for the fiscal year ended June 30, 2018, as filed with the Securities Exchange Commission on August 23, 2018. For time-based restricted stock unit awards, the grant date fair value was determined using the closing share price of the Company’s common shares on the date of grant. For the performance-based restricted stock unit awards, the grant-date fair value is calculated based on the probable outcome of the attainment of the respective pre-established performance objectives as of the grant date at target attainment (which is the maximum level of attainment). .

(1)	Reflects potential payouts under the annual bonus program tied to attainment of Company performance goals. The actual payout is reported in the Non-Equity Incentive Compensation column in the Summary Compensation Table.
(2)	Each named executive officer was granted performance based restricted stock units under our 2009 Share Option/Share Issuance Plan covering the target number of shares specified in the table which represents the maximum number of shares that may be earned under the award. The actual number that may vest will be based on the level of achievement of a performance goal based on earnings per share and revenue measured over the 2018 calendar year period and continued service through March 15, 2022. The minimum number of shares that can be earned under the awards assumes that each goal is attained at or higher than the threshold level; attainment of either goal at lower than the threshold will result in no payout. Such awards are also subject to accelerated vesting in the event of a change in control of our company as further described in “Agreements Regarding Employment, Change in Control and Termination of Employment.”
(3)	Each restricted stock unit award was granted under our 2009 Share Option/Share Issuance Plan. The units vest annually over a four-year period of service measured from March 15, 2018. Such units are also subject to accelerated vesting in the event of a change in control of our company as further described in “Agreements Regarding Employment, Change in Control and Termination of Employment.”
(4)	Reflects the grant-date fair value of the restricted stock unit awards as calculated in accordance with FASB ASC Topic 718 without taking into account any estimated forfeitures related to service vesting conditions.

Agreements Regarding Employment, Change in Control and Termination of Employment

Employment Agreement and Retention Agreements

We have entered into an employment agreement with Dr. Mike Chang and retention agreements with each of our other named executive officers.

Pursuant to his April 28, 2010 employment agreement, Dr. Mike Chang is entitled to a base salary of $325,000 per year. His base salary is subject to annual review and may be adjusted by our Compensation Committee at its discretion and is currently $440,524. In addition, Dr. Chang is eligible to receive a cash bonus in an amount determined by our Compensation Committee based on attainment of specified performance goals. Dr. Chang is also entitled to participate in the benefit plans

43

generally available to our employees, such as group health care coverage and 401(k) plan participation.

  Under the terms of his employment agreement, should Dr. Mike Chang's employment be involuntarily terminated by us without cause or by him for good reason at any time other than during the 12 months following a change in control of the Company, he will be entitled to receive (i) continued base salary for a period of 12 months and (ii) continued health care coverage for himself and his eligible dependents for a period of 12 months. Should Dr. Chang's employment be involuntarily terminated by us without cause or by him for good reason within 12 months following a change in control of the Company, he will be entitled to receive (i) continued base salary for a period of 24 months, (ii) continued health care coverage for himself and his eligible dependents for a period of 24 months, and (iii) accelerated vesting of his then unvested equity awards.

Pursuant to the retention agreements, each of our other named executive officers is entitled to receive severance payments and benefits upon an involuntary termination of his or her employment. Should the named executive officer's employment be involuntarily terminated by us without cause or by him or her for good reason at any time other than during the 12 months following a change in control of the Company, he or she will be entitled to receive (i) continued base salary for a period of 6 months, and (ii) continued health care coverage for himself and his eligible dependents for a period of 6 months. In the event that such involuntary termination occurs within 12 months following a change in control of the Company, then the named executive officer will be entitled to receive (i) continued base salary for a period of 6 months, (ii) continued health care coverage for himself/herself and his/her eligible dependents for a period of 6 months and (iii), each outstanding unvested equity award held by the terminated executive officer will accelerate with respect to that number of shares that would have vested had the officer remained in service for an additional 12 months.

 If any payment or benefit in connection with a change in control or the subsequent termination of Dr. Mike Chang's or a named executive officer's employment would be subject to an excise tax under Section 280G of the Internal Revenue Code, then such payment of benefit will be reduced to the extent necessary to maximize his net after tax benefits.

 As a condition to the severance payments and benefits, each named executive officer (including Dr. Mike Chang) must deliver a general release of all claims against us and our affiliates. In addition, severance benefits are conditioned on the executive's continued compliance with non-compete and non-solicitation restrictive covenants for the severance period.

 For purposes of Dr. Mike Chang's employment agreement and the retention agreements with our named executive officers, the following definitions will be in effect:

A change in control will be deemed to occur upon (i) a merger, consolidation or other reorganization approved by our shareholders, unless our shareholders continue to own more than fifty percent (50%) of the total combined voting power of the voting securities of the successor corporation; (ii) a sale of all or substantially all of our assets; or (iii) the acquisition by any person or related group of persons of more than fifty percent (50%) of the total combined voting power of our outstanding securities.

 A resignation for good reason will be deemed to occur should the individual resign from his employment with us for any of the following reasons during the applicable change in control protection period: (i) a material diminution in his authorities, duties or responsibilities; (ii) a reduction in his base compensation; (iii) a material relocation of his existing work site; or (iv) any material breach by us of any provision of any agreement we have with such individual.

An individual's employment will be deemed to have been terminated for cause if such termination occurs by reason of: (i) the commission of any act of fraud, embezzlement or dishonesty by the individual or his conviction of a felony, (ii) any unauthorized use or disclosure by the individual of confidential information or trade secrets of the Company (or any parent or subsidiary), (iii) any other misconduct by the individual adversely affecting the business or affairs of the Company in a material manner, (iv) the individual's failure to cure any breach of his obligations under certain agreements with the Company, or (v) the individual's breach of any of his fiduciary duties as an officer or director of the Company.

Option and Restricted Stock Unit Acceleration

The options and time-based restricted stock units awards granted to our named executive officers under our various equity plans will each vest on an accelerated basis as to all the shares in the event those options or awards are not assumed or otherwise replaced in connection with certain changes in control or ownership of the Company. In the event of such changes, the performance-based restricted stock units will convert into (i) the right to receive 50% of the number of target shares subject to the award in the event such change occurs prior to completion of the performance period and (ii) the right to receive the number of shares based on actual performance if such change occurs after completion of the performance period, subject in each case to continued service requirements; such shares will vest on an accelerated basis in the event those awards are not

44

assumed or otherwise continued or replaced in connection with the change in control or ownership. The table below sets forth the intrinsic value of the options and the restricted stock unit awards held by each named executive officer that would accelerate in full (in accordance with the terms of the equity plans governing those options and awards) upon a change in control or ownership in which those options or awards and restricted stock units were not assumed or replaced had such change in control or ownership occurred on June 30, 2018:

Yifan Liang	$	2,156	$	917,982
Yueh-Se Ho	$	—	$	782,210
Daniel Kuang Ming Chang	$	—	$	610,782

(1	)	Such intrinsic value is determined by multiplying (A) the amount by which the fair market value per common share on June 30, 2018 ($14.24 per share) exceeded the exercise price per share in effect under each option by (B) the number of unvested shares that would vest on an accelerated basis under such option.
(2	)	Such value is determined by multiplying (A) the fair market value per common share on June 30, 2018 ($14.24 per share) by (B) the number of unvested shares that would vest on an accelerated basis under such award.

Termination in Connection with Change in Control. The following table provides the total dollar value of the compensation that each named executive officer would be entitled to receive if his or her employment was terminated without cause or he or she resigned for good reason on June 30, 2018 in connection with a change in control of the Company in which the outstanding awards are assumed, replaced or otherwise continued. If the outstanding awards are not assumed, replaced or otherwise continued in effect, then those awards will accelerate in whole or in part of at the time of the change in control and the value of the acceleration will instead be as set forth in the table above titled:" Option and Restricted Stock Unit Acceleration".

CEO PAY RATIO

We are required to disclose the median annual total compensation of our worldwide employees, the total compensation of our Chief Executive Officer and the ratio of these two amounts.

For fiscal year 2018, Dr. Mike Chang’s total annual compensation as disclosed in the Summary Compensation Table was $3,613,595, and the total annual compensation for our median employee, located in China, was $13,702, resulting in a pay ratio of 264:1.

To help understand this disclosure, it is important to provide context to our operations and employee population. Of our total employee population of 3,347 employees, only 586 employees (i.e. approximately 18%) are located in the U.S. and 82% are located outside the U.S., and 79% of our employees work in China. The majority of the positions in China are hourly direct labor. The median employee is an hourly-paid factory worker at our manufacturing facilities in China who in fiscal year 2018 earned the U.S. dollar equivalent of $13,702, which is competitive pay for this position in China but significantly lower than the salary paid for a similar position in the U.S. Our ratio is thus impacted by our strategy to source our core manufacturing in China.

In light of the significant percentage of employees located outside of the U.S., and in the interest of providing additional disclosures that investors and shareholders may find meaningful, we also conducted two supplemental pay ratio calculations based on the same methodology and assumptions used in calculating the pay ratio for the median employee based on the entire employee population, as described below. For the first one, we compared Chief Executive Officer pay with compensation of all our employees other than hourly direct labor employees in China (this alternate group was comprised of 1,604 employees worldwide, including China) which resulted in a median employee with total U.S. dollar equivalent compensation of $40,605

46

and a pay ratio of 89:1. For the second calculation, we included only our U.S. employees which resulted in a median employee with compensation equal to $89,170 and a pay ratio of 41:1.

We used the following methodology and assumptions to identify the median employee and calculate the annual total compensation of the median-paid employee:

• We selected June 29, 2018 as the date on which to determine our median employee. As of that date, we had approximately 3,347 employees, of which approximately 2,761 were located outside the U.S.

• SEC regulations allow employers to identify the median based on a “consistently applied compensation measure” (CACM). We used (A) annualized base salary plus (B) overtime pay plus (C) bonus or other incentive compensation for fiscal year 2017 as our CACM because these elements are consistently available across all countries where we have employees. Base pay for hourly employees was calculated based on a reasonable estimate of hours worked (including overtime) in 2017, and on salary levels for all remaining employees.

• We ranked this compensation measure for our employees from lowest to highest. This calculation was performed for all employees except our CEO, Dr. Mike Chang, whether employed on full-time or part-time. We converted amounts paid in foreign currencies to the U.S. dollar based on the exchange rates on June 29, 2018.

• As indicated above, we performed two additional calculations: one involved excluding our direct labor employees in China and the second one involved including only our U.S. employees.

The pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our internal records and the methodology described above. Because the SEC rules for identifying the median compensated employee and calculating pay ratio allow companies to adopt a variety of methodologies, apply certain exclusions, and make reasonable estimates and assumptions that reflect their employee populations and compensation practices, our pay ratio may not be comparable to the pay ratios reported by other companies.

As of June 30, 2018, 128,980 common shares were available for issuance under the ESPP, and 3,027,708 common shares were available for issuance under the 2009 Plan. The 3,027,708 shares available for issuance under the 2009 Plan may be issued upon the exercise of stock options or stock appreciation rights, or those shares may be issued as stock bonuses or pursuant to restricted stock awards or RSUs which vest upon the attainment of prescribed performance milestones or the completion of designated service periods.
(6	)	The number of common shares available for issuance under the 2009 Share Option/Share Issuance Plan automatically increases in January each calendar year during the term of the 2009 Plan, by the lesser of 3% of the total number of common shares outstanding on the last trading day of December in the immediately preceding calendar year, or 750,000 shares. The number of common shares available for issuance under the ESPP established in May 2010 automatically increases in January of each calendar year during the term of the ESPP, by the lesser of 0.75% of the outstanding common shares on the last trading day of December in the immediately preceding calendar year, or 250,000 shares.

Policies and Procedures

The Audit Committee of the Board of Directors is responsible for establishing policies and procedures for reviewing and approving all related party transactions as defined under Securities and Exchange Commission rules and regulations.

In determining whether to approve or ratify an Interested Transaction, the Audit Committee will take into account all factors that it deems appropriate, including whether the Interested Transaction is negotiated or consummated on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances and the extent of the related party’s interest in the transaction. The Policy also provides that no director shall participate in any discussion or approval of an Interested Transaction for which he or she is a related party, except that the director shall provide all material information concerning the Interested Transaction to the Audit Committee

The Policy provides a list of Interested Transactions that are deemed to be pre-approved by the Audit Committee such that no separate approval will be required by the Audit Committee, including:

• Employment of executive officer if the compensation is approved by the Compensation Committee;

• Compensation of directors that is consistent with the Company’s director compensation policies and required to be disclosed in the proxy statement;

• Transaction with another company where the related party’s relationship is an employee (other than executive officer or director) or a stockholder, if the value of the transaction does not exceed the greater of $1,000,000 or 2% of such company’s annual revenue; and

52

• Certain charitable contributions if the aggregate amount does not exceed $1,000,000 or 2% of the organization’s annual revenue.

REPORT OF THE AUDIT COMMITTEE

The following is the report of the Audit Committee with respect to our audited financial statements for the fiscal year ended June 30, 2018. The information contained in this report shall not be deemed to be “soliciting material” or to be “filed” with the SEC, nor shall such information be incorporated by reference into any future filing under the Securities Act of 1933, as amended, except to the extent that the company specifically incorporates the information by reference in such filing.

The Audit Committee is comprised of three independent directors: Mr. Michael L. Pfeiffer, its Chairman, and Messrs. Michael J. Salameh and Mr. Robert I. Chen. The purpose of the Audit Committee is to assist our Board of Directors in its general oversight of our financial reporting, internal controls and audit functions. The Audit Committee is directly responsible for the appointment, retention, evaluation, compensation, oversight and termination of our independent registered public accounting firm.

The Audit Committee reviews the results and scope of audit and other services provided by the independent auditors and reviews the accounting principles and auditing practices and procedures to be used in our financial reporting process, including its systems of internal control, and in the preparation of consolidated financial statements in accordance with generally accepted accounting principles. Our independent registered public accounting firm for the last fiscal year, Grant Thornton LLP (“Grant Thornton”), was responsible for performing an independent audit of those financial statements. As more fully explained in the Audit Committee's charter, the Audit Committee's responsibility is to provide oversight of and to review those processes. The Audit Committee does not conduct auditing or accounting reviews or procedures, and relies on information and representations provided by management and the independent auditors. The Audit Committee has relied on management's representation that the financial statements have been prepared with integrity and objectivity and in conformity with accounting principles generally accepted in the United States and on the representations of the independent registered public accounting firm included in their report on our financial statements.

The Audit Committee has reviewed and discussed the audited financial statements with our management. Management is responsible for maintaining adequate internal control over financial reporting and for assessing the effectiveness of internal control over financial reporting. The Audit Committee was kept apprised of the progress of management's assessment of our internal control over financial reporting and provided oversight to management during the process. In connection with this oversight, the Audit Committee received periodic updates provided by management at meetings throughout the year. At the conclusion of the process, management provided the Audit Committee with a report on the effectiveness of our internal control over financial reporting. The Audit Committee reviewed this report of management and Item 9A, “Control and Procedures,” contained in our Annual Report on Form 10-K for the fiscal year ended June 30, 2017 filed with the SEC, as well as Grant Thornton's reports of independent registered public accounting firm (included in our Annual Report on Form 10-K) relating to its audits of the consolidated financial statements and of internal control over financial reporting. The Audit Committee has reviewed with management and Grant Thornton (a) matters related to the conduct of the audit of the consolidated financial statements by the independent registered public accounting firm and its audit of internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, as amended and (b) the additional analyses undertaken and procedures performed by us to support certifications by our Chief Executive Officer and Chief Financial Officer that are required by the SEC and the Sarbanes-Oxley Act of 2002 to accompany our periodic filings with the SEC.

In addition, the Audit Committee has reviewed and discussed the audited financial statements with Grant Thornton, including such items set forth in Public Company Accounting Oversight Board (PCAOB) Auditing Standard No. 16, Communications with Audit Committees or any successor standard. The Audit Committee has received from the independent registered public accounting firm, Grant Thornton, the written disclosures and the letter required by the PCAOB, and the Audit Committee has discussed with Grant Thornton the independence of the independent registered public accounting firm.

After review of all discussions and all written correspondence described above, as well as such other matters deemed relevant and appropriate by the Audit Committee, the Audit Committee recommended to our Board of Directors that the audited financial statements for the last fiscal year be included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2018.

PROPOSAL NO. 5

Ratification of Appointment of Independent Registered Public Accounting Firm

The Audit Committee has selected BDO USA, LLP (“BDO”) as our independent registered public accounting firm to conduct the audit for the fiscal year ending June 30, 2019. BDO will review our consolidated financial statements for the quarter ended September 30, 2018 which will appear in our quarterly report on Form 10-Q with the SEC. Shareholders are asked to approve and ratify the appointment of BDO as our independent registered public accounting firm, and to authorize our Board of Directors, acting through our Audit Committee, to determine the remuneration of such accounting firm.

On September 11, 2018, the Company notified Grant Thornton LLP (“Grant Thornton”) of its dismissal as the Company’s independent registered public accounting firm effective as of that date. Grant Thornton also notified the Company to confirm that its audit relationship with the Company has ceased as of September 11, 2018. The decision to change independent registered public accounting firms was approved by the Audit Committee.

The reports of Grant Thornton on Company's consolidated financial statements as of and for the fiscal years ended June 30, 2018 and 2017 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principle.

During the two fiscal years ended June 30, 2018 and the subsequent interim period through September 11, 2018, there were no disagreements as described under Item 304(a)(1)(iv) of Regulation S-K with Grant Thornton on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to Grant Thornton’s satisfaction, would have caused Grant Thornton to make reference to the subject matter thereof in connection with its reports on the financial statements of the Company for such years. In addition, during the two fiscal years ended June 30, 2018 and the subsequent interim period through September 11, 2018, there were no reportable events as described under Item 304(a)(1)(v) of Regulation S-K.

The Company has provided Grant Thornton with a copy of the above disclosure prior to the filing of this Proxy Statement and previously requested that Grant Thornton furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with such disclosure in a Current Report on Form 8-K. A copy of Grant Thornton's letter, dated September 17, 2018, is attached as Exhibit 16.1 to the Form 8-K filed on September 17, 2018.

On September 17, 2018, the Audit Committee and the Board of Directors of the Company approved the engagement of BDO USA, LLP (“BDO”) to serve as the Company's independent registered public accounting firm.

During the two most recent fiscal years, and in the subsequent interim periods through September 17, 2018, neither the Company nor anyone acting on its behalf has consulted with BDO regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on the Company's financial statements, and either a written report was provided to the Company or oral advice was provided that BDO concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K). In addition, the Company has provided a copy of the above disclosure to BDO prior to the filing of this Proxy Statement.

FUTURE SHAREHOLDER PROPOSALS AND NOMINATIONS FOR

THE 2019 ANNUAL GENERAL MEETING

Under Rule 14a-8 of the Exchange Act, for a shareholder proposal to be considered for inclusion in the proxy statement for the 2019 annual general meeting of shareholders, we must have received the written proposal by such shareholder no later than June 11, 2019. Such proposals must comply with the other provisions of Rule 14a-8 and additional applicable SEC rules regarding the inclusion of shareholder proposals in the proxy materials. In addition, the proxy solicited by the Board of Directors for the Annual Meeting in 2018 will confer discretionary authority to vote on any shareholder proposal presented at that meeting, if we do not receive notice of such proposal prior to September 9, 2019.

If you wish to bring a matter before an annual general meeting and the proposal is submitted outside the process of Rule 14a-8, you may use the procedures set forth in the Bye-laws to make a shareholder proposal, including director nominations, not intended to be included in our proxy statement under Rule 14a-8 so long as such proposal complies with our Bye-laws. Shareholder nominations and proposals may be voted on at an annual general meeting of shareholders only if such nominations and proposals are submitted to us pursuant to written notice timely and accompanied by certain information. To be timely, a shareholder's written notice must be received by us not less than 60 nor more than 180 days to the date set for the annual general meeting of shareholders (or if no such date is set, the date that is not less than 60 nor more than 180 days prior to the anniversary of the previous year's annual general meeting of shareholders). The notice must contain the information specified in Sections 59 and 60 of our Bye-laws with respect to the person to be nominated as director and include all material information on the proposal, statement or resolution to be put to the meeting, together with details of shareholder submitting the proposal, statement or resolution and such other information as may from time to time be specified by our Board. Under Section 60(4) of Bye-laws, the advance notice must include, but are not limited to, the following information:

• the meeting at which the person nominated is proposed for election as a director;

• information relating to direct and indirect beneficial ownership of shares, including ownership of derivative instrument, by the shareholders and their affiliates and associates acting in concert with the shareholders;

• any agreement, arrangement, relationship by the shareholders that may increase or decrease the voting power of the shareholders;

• a description of direct and indirect compensation, material monetary agreement and other related party transactions between the shareholders and their affiliates and associated acting in concert therewith and the nominees;

• a signed questionnaire by the nominee regarding his or her background, qualifications and other representations;

• a written consent of the nominee to his being named in a proxy statement as a nominee and to serve as a Director, if elected; and

• any other information relating to such shareholder that would be required to be disclosed in the proxy statement under the Exchange Act;

In addition, the shareholder will be required to update and supplement, if necessary, the advance notice so the information is true and correct as of date of the annual meeting and as of the date that is 10 business days from the meeting. Our Board of Directors will review proposals from eligible shareholders which it receives by that date and will determine whether any such proposal has been received in accordance with the Bye-laws and whether any such proposal will be acted upon at the annual general meeting of shareholders. All shareholder proposals and shareholder nominations should be mailed to Alpha and Omega Semiconductor Limited, Board of Directors, c/o Investor Relations, Alpha and Omega Semiconductor, Inc. 475 Oakmead Parkway, Sunnyvale, CA 94085.

Moreover, Section 79 of the Companies Act 1981 of Bermuda, as amended, provides that shareholders representing either (i) 5% of the total voting rights of the shares eligible to vote at a general meeting of shareholders, or (ii) not less than 100 shareholders may propose any resolution which may properly be moved at the next annual general meeting of shareholders. Upon timely receipt of notice, we shall, at the expense of such shareholder(s), give our other shareholders entitled to receive notice of the next annual general meeting of shareholders notice of such proposed resolution. To be timely, the proposal requiring notice of a resolution must be deposited at our registered office at least six weeks before the next annual general meeting of shareholders. Shareholders satisfying the criteria of Section 79 may also require us to circulate a statement in

57

respect of any matter to come before an annual general meeting of shareholders by notice deposited at our registered office not less than one week prior to the annual general meeting of shareholders.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

The members of the Board of Directors, the executive officers of the Company and persons who beneficially own more than ten percent of the outstanding common shares are subject to the reporting requirements of Section 16 of the Securities Exchange Act of 1934, as amended, which require them to file reports with respect to their beneficial ownership of the common share and their transactions in such common shares. Based upon (i) the copies of Section 16 reports which the Company received from such persons for their fiscal year 2018 transactions in the common shares and their common share holdings, and (ii) written representation that no other reports were required, the Company believes that all reporting requirements under Section 16 for such year were met in a timely manner by its directors, executive officers and greater than ten percent beneficial owners.

The Plan serves as the successor to the Company’s 2009 Share Option/Share Issuance Plan (the “Predecessor Plan”), and no further awards shall be made under the Predecessor Plan on or after the Plan Effective Date. All awards outstanding under the Predecessor Plan on the Plan Effective Date shall remain outstanding under the Predecessor Plan and shall continue to be governed solely by the terms of the documents evidencing such award, and no provision of the Plan shall be deemed to affect or otherwise modify the rights or obligations of the holders of such awards.

A - 2

(b)    Subject to adjustment pursuant to Section 1.5(f), the maximum number of Common Shares that may be issued pursuant to Incentive Options granted under the Plan shall be One Million Two Hundred Sixty-Five Thousand (1,265,000).

(c)    Subject to adjustment pursuant to Section 1.5(f), the maximum number of Common Shares for which Awards that are settled in shares may be made to any person under the Plan in any fiscal year shall not exceed Eight Hundred Thousand (800,000) shares in the aggregate.

(d)    The maximum aggregate number of Common Shares for which Awards may made to any Non-Employee Director under the Plan in any calendar year, taken together with any cash retainer paid to such Non-Employee Director in respect of such calendar year, shall not exceed $750,000 ($1,000,000 in the calendar year in which the Non-Employee Director is initially elected or appointed to the Board)in total value (calculating the value of any such Awards based on the grant date fair value of such Awards for financial reporting purposes and excluding, for this purpose, the value of any dividends or dividend equivalents paid on any Common Shares or Awards).

Upon the exercise of any share appreciation right under the Plan, the share reserve shall be reduced by the gross number of shares as to which such right is exercised. Should the exercise price of an option or any Withholding Taxes incurred in connection with the exercise of an option or share appreciation right under the Plan be paid with Common Shares (whether through the withholding of a portion of the otherwise issuable shares or through the tender of actual outstanding shares), then in each such case, the shares so tendered or withheld shall not be added to the Common Shares available for grant under the Plan. If Common Shares otherwise issuable under the Plan are withheld by the Company in satisfaction of the Withholding Taxes incurred in connection with the vesting or settlement of an Award (including an award granted under the Predecessor Plan) other than an option or share appreciation right, then in each such case the Common Shares so tendered or withheld shall be added back to the Common Shares available for issuance under the Plan.

(f)    Should any change be made to the Common Shares by reason of any share split, share dividend, recapitalization, combination of shares, exchange of shares, spin-off transaction, extraordinary distribution (whether in cash, securities or other property) or other change affecting the outstanding Common Shares as a class without the Company’s receipt of consideration, or should the value of outstanding Common Shares be substantially reduced as a result of a spin-off transaction or an extraordinary dividend or distribution, or should there occur any merger, consolidation, reincorporation or other reorganization, then equitable adjustments shall be made by the Plan Administrator to (i) the maximum number and/or class of securities issuable under the Plan, (ii) the maximum number and/or class of securities for which any one person may be granted Awards under the Plan in any fiscal year, (iii) the maximum number and/or class of securities that may be issued pursuant to Incentive Options, (iv) the number and/or class of securities and the exercise or base price per share in effect under each outstanding Award under the Plan (including awards under the Predecessor Plan)and the consideration (if any) payable per share, and (v) the number and/or class of securities subject to cancellation or the Company’s outstanding repurchase rights under the Plan and the repurchase price payable per share. The adjustments shall be made in such manner as the Plan Administrator deems appropriate and such adjustments shall be final, binding and conclusive. In addition, in the event of a Change in Control, the provisions of Section 2.7 shall apply.

A - 3

(g)    Awards may, in the sole discretion of the Plan Administrator, be granted under the Plan in assumption of, or in substitution for, outstanding awards previously granted by an entity directly or indirectly acquired by the Company or with which the Company combines (“Substitute Awards”). Substitute Awards shall not be counted against the share limit (nor shall Substitute Awards be added to the share limit as provided above); provided, that Substitute Awards issued in connection with the assumption of, or in substitution for, outstanding options intended to qualify as Incentive Options within the meaning of Section 422 of the Code shall be counted against the aggregate number of Common Shares available for Awards of Incentive Options under the Plan. Subject to applicable stock exchange requirements, available shares under a shareholder approved plan of an entity directly or indirectly acquired by the Company or with which the Company combines (as appropriately adjusted to reflect the acquisition or combination transaction) may be used for Awards under the Plan and shall not reduce (or be added back to) the number of Common Shares available for issuance under the Plan.

(h)    Outstanding Awards granted pursuant to the Plan shall in no way affect the right of the Company to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets.

(A)    cash or check made payable to the Company,

A - 4

(D)    to the extent the option is exercised for vested Common Shares, through a special sale and remittance procedure pursuant to which the Participant shall concurrently provide instructions to (a) a brokerage firm (reasonably satisfactory to the Company for purposes of administering such procedure in compliance with the Company’s pre-clearance/pre-notification policies) to effect the immediate sale of the purchased shares and remit to the Company, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate exercise price payable for the purchased shares plus all applicable income and employment taxes required to be withheld by the Company by reason of such exercise and (b) the Company to deliver the certificates for the purchased shares directly to such brokerage firm on such settlement date in order to complete the sale.

Except to the extent such sale and remittance procedure is utilized, payment of the exercise price for the purchased shares must be made on the Exercise Date.

(iii)    The Plan Administrator shall have the discretion (exercisable at any time) to permit the exercise price of an outstanding option to be paid in one or more of the forms specified in Section 2.1(b)(ii).

(c)    Exercise and Term of Options. Each option shall be exercisable at such time or times, during such period and for such number of shares as shall be determined by the Plan Administrator and set forth in the Award Agreement evidencing the option. However, no option shall have a term in excess of ten (10) years measured from the option grant date.

(d)    Effect of Termination of Service.

(i)     The following provisions shall govern the exercise of any options that are outstanding at the time of the Participant’s cessation of Service or death:

(A)Any option outstanding at the time of the Participant’s cessation of Service for any reason shall remain exercisable for such period of time thereafter as shall be determined by the Plan Administrator and set forth in the documents evidencing the option, but no such option shall be exercisable after the expiration of the option term.

(B)Any option held by the Participant at the time of the Participant’s death and exercisable in whole or in part at that time may be subsequently exercised by the personal representative of the Participant’s estate or by the person or persons to whom the option is transferred pursuant to the Participant’s will or the laws of inheritance or by the Participant’s designated beneficiary or beneficiaries of that option.

(C)Should the Participant’s Service be terminated for Misconduct or should the Participant otherwise engage in Misconduct while holding one or more outstanding options, then all of those options shall terminate immediately and cease to be outstanding.

(D)During the applicable post-Service exercise period, the option may not be exercised for more than the number of vested shares for which the option is at the time exercisable. No additional shares shall vest under the option following the Participant’s cessation of Service except to the extent (if any) specifically authorized by the Plan Administrator in its sole discretion pursuant to an express written agreement with the Participant. Upon the expiration of the applicable exercise period or (if earlier) upon the expiration of the option term, the option shall terminate and cease to be outstanding for any shares for which the option has not been exercised.

A - 5

(B)    include an automatic extension provision whereby the specified post-Service exercise period in effect for any option shall automatically be extended by an additional period of time equal in duration to any interval within the specified post-Service exercise period during which the exercise of that option or the immediate sale of the shares acquired under such option could not be effected in compliance with applicable federal and state securities laws, but in no event shall such an extension result in the continuation of such option beyond the expiration date of the term of that option; and/or

(C)    permit the option to be exercised, during the applicable post-Service exercise period, not only with respect to the number of vested Common Shares for which such option is exercisable at the time of the Participant’s cessation of Service but also with respect to one or more additional installments in which the Participant would have vested had the Participant continued in Service.

(e)    Early Exercise. The Plan Administrator shall have the discretion to grant options which are exercisable for unvested Common Shares. Should the Participant cease Service while holding unvested shares received upon such early exercise of an option, the Company shall have the right to repurchase any or all of those unvested shares at a price per share equal to the lower of (i) the exercise price paid per share or (ii) the Fair Market Value per Common Share at the time of repurchase. The terms upon which such repurchase right shall be exercisable (including the period and procedure for exercise and the appropriate vesting schedule for the purchased shares) shall be established by the Plan Administrator and set forth in the document evidencing such repurchase right.

(f)    Incentive Options. The terms specified below shall be applicable to all Incentive Options. Except as modified by the provisions of this Section 2.1(f), all the provisions of the Plan shall be applicable to Incentive Options. Options which are specifically designated as Non-Statutory Options when issued under the Plan shall not be subject to the terms of this Section 2.1(f).

(i)    Eligibility. Incentive Options may only be granted to Employees.

(ii)    Dollar Limitation. The aggregate Fair Market Value of the Common Shares (determined as of the respective date or dates of grant) for which one or more options granted to any Employee under the Plan (or any other option plan of the Company or any Parent or Subsidiary) may for the first time become exercisable as Incentive Options during any one calendar year shall not exceed the sum of One Hundred Thousand Dollars ($100,000).

To the extent the Employee holds two (2) or more such options which become exercisable for the first time in the same calendar year, then for purposes of the foregoing limitations on the exercisability of those options as Incentive Options, such options shall be deemed to

A - 6

become first exercisable in that calendar year on the basis of the chronological order in which they were granted, except to the extent otherwise provided under applicable law or regulation.

(i)One or more Participants may be granted a Stand-alone Right not tied to any underlying option. The Stand-alone Right shall relate to a specified number of Common Shares and shall be exercisable upon such terms and conditions as the Plan Administrator may establish.

(a)Authority. The Plan Administrator shall have full power and authority, exercisable in its sole discretion, to grant share awards either as vested or unvested Common Shares, through direct and immediate issuances.

(ii)past services rendered to the Company (or any Parent or Subsidiary); or

(iii)any other valid consideration under the Companies Act 1981 of Bermuda, as amended.

(c)Vesting Provisions.

(i)Share awards may, in the discretion of the Plan Administrator, be fully and immediately vested upon issuance as a bonus for Service rendered or may vest in one or more installments over the Participant’s period of Service and/or upon the attainment of specified performance objectives.

(ii)The Plan Administrator shall also have the discretionary authority to structure one or more share awards so that the Common Shares subject to those Awards shall vest upon the achievement of pre-established performance objectives based on one or more Performance Goals and measured over the performance period specified by the Plan Administrator at the time of the grant of the

A - 8

Award.The elements of the vesting schedule applicable to any share award shall be determined by the Plan Administrator and incorporated into the Award Agreement.

(iii)Should the Participant cease to remain in Service while holding one or more unvested Common Shares issued under a share award or should the performance objectives not be attained with respect to one or more such unvested Common Shares, then those shares shall be immediately surrendered to the Company for cancellation, and the Participant shall have no further shareholder rights with respect to those shares. To the extent the surrendered shares were previously issued to the Participant for consideration paid in cash or cash equivalent, the Company shall repay to the Participant the lower of (i) the cash consideration paid for the surrendered shares or (ii) the Fair Market Value of those shares at the time of cancellation.

(iv)The Plan Administrator may in its discretion waive the surrender and cancellation of one or more unvested Common Shares which would otherwise occur upon the cessation of the Participant’s Service or the non-attainment of the performance objectives applicable to those shares. Any such waiver shall result in the immediate vesting of the Participant’s interest in the Common Shares as to which the waiver applies.

(v)Any new, substituted or additional securities or other property (including money paid other than as a regular cash dividend) which the Participant may have the right to receive with respect to the Participant’s unvested Common Shares by reason of any share dividend, share split, recapitalization, combination of shares, exchange of shares, spin-off transaction, extraordinary dividend or distribution or other change affecting the outstanding Common Shares as a class without the Company’s receipt of consideration shall be issued subject to (i) the same vesting requirements applicable to the Participant’s unvested Common Shares and (ii) such escrow arrangements as the Plan Administrator shall deem appropriate, unless and to the extent the Plan Administrator determines at the time to vest and distribute such securities or other property. Equitable adjustments to reflect each such transaction shall also be made by the Plan Administrator to the repurchase price payable per share by the Company for any unvested securities subject to its existing repurchase rights under the Plan; provided the aggregate repurchase price shall in each instance remain the same.

2.4RESTRICTED SHARE UNITS

(a)    Authority. The Plan Administrator shall have the full power and authority, exercisable in its sole discretion, to grant restricted share units evidenced by an Award Agreement in the form approved by the Plan Administrator; provided, however, that the terms of each such agreement shall not be inconsistent with the terms specified below.

A - 9

(b)    Terms. Each restricted share unit award shall entitle the Participant to receive the shares underlying that Award (or an amount based on the value of the shares) upon vesting or upon the expiration of a designated time period following the vesting of the Award. Payment of shares underlying a restricted share unit award may be deferred for a period specified by the Plan Administrator at the time the restricted share unit award is initially granted or (to the extent permitted by the Plan Administrator) designated by the Participant pursuant to a timely deferral election made in accordance with the requirements of Code Section 409A.Restricted share units subject to performance vesting may also be structured so that the underlying shares are convertible into Common Shares (or a payment based on the value of the shares), but the rate at which each share is to so convert shall be based on the attained level of performance for each applicable performance objective.

(c)    Vesting Provisions.

(i)Restricted share units may, in the discretion of the Plan Administrator, vest in one or more installments over the Participant’s period of Service or upon the attainment of specified performance objectives.

(ii)The Plan Administrator shall also have the discretionary authority to structure one or more restricted share unit awards so that the Common Shares subject to those Awards shall vest (or vest and become issuable) upon the achievement of pre-established performance objectives based on one or more Performance Goals and measured over the performance period specified by the Plan Administrator at the time of the grant of the Award.

(iii)Outstanding restricted share units shall automatically terminate without any payment if the performance goals or Service requirements established for those Awards are not attained or satisfied. The Plan Administrator, however, shall have the discretionary authority to make a payment under one or more outstanding Awards of restricted share units as to which the designated performance goals or Service requirements have not been attained or satisfied.

(d)    Payment. Restricted share units that vest may be settled in (i) cash, (ii) Common Shares valued at Fair Market Value on the payment date or (iii) a combination of cash and Common Shares, as determined by the Plan Administrator in its sole discretion and set forth in the Award Agreement.

2.5DIVIDEND EQUIVALENT RIGHTS

(a)Authority. The Plan Administrator shall have full power and authority, exercisable in its sole discretion, to grant dividend equivalent rights evidenced by an Award Agreement in the form approved by the Plan Administrator; provided however, that the terms of each such agreement shall not be inconsistent with the terms specified below.

(b)Terms. The dividend equivalent rights may be granted as stand-alone awards or in tandem with other Awards made under the Plan, except dividend equivalent rights shall not be granted in connection with an option or share appreciation right. The term of each dividend equivalent right award shall be established by the Plan Administrator at the time of grant, but no such award shall have a term in excess of ten (10) years.

(c)Entitlement. Each dividend equivalent right shall represent the right to receive the economic equivalent of each dividend or distribution, whether in cash, securities or other property (other

A - 10

than Common Shares), which is made per issued and outstanding Common Share during the term the dividend equivalent right remains outstanding. A special account on the books of the Company shall be maintained for each Participant to whom a dividend equivalent right is granted, and that account shall be credited per dividend equivalent right with each such dividend or distribution made per issued and outstanding Common Share during the term of that dividend equivalent right remains outstanding.

(d)Timing of payment. Payment of the amounts credited to such book account shall not be made to the Participant prior to the vesting of that Award (or the portion thereof to which the dividend equivalent right award relates) and shall accordingly be subject to cancellation and forfeiture to the same extent as the underlying Award. Payment may be deferred for a period specified by the Plan Administrator at the time the dividend equivalent right award is initially granted or (to the extent permitted by the Plan Administrator) designated by the Participant pursuant to a timely deferral election made in accordance with the requirements of Code Section 409A.

(e)Form of payment. Payment of the amounts due with respect to dividend equivalent rights may be made in (i) cash, (ii) Common Shares or (iii) a combination of cash and Common Shares, as determined by the Plan Administrator in its sole discretion and set forth in the Award Agreement. If payment is to be made in the form of Common Shares, the number of Common Shares into which the cash dividend or distribution amounts are to be converted for purposes of the Participant’s book account may be based on the Fair Market Value per Common Share on the date of conversion, a prior date or an average of the Fair Market Value per Common Share over a designated period, as determined by the Plan Administrator in its sole discretion.

2.6OTHER SHARE-BASED AWARDS

The Plan Administrator may grant other Awards denominated in Common Shares (including performance shares or performance units) under the Plan, alone or in tandem with other Awards, in such amounts as the Plan Administrator shall from time to time in its sole discretion determine. Each Other Share-Based Award granted under the Plan shall be evidenced by an Award Agreement in the form approved by the Plan Administrator. Each Other Share-Based Award so granted shall be subject to such conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement.

2.7EFFECT OF CHANGE IN CONTROL

(a)In the event of a Change in Control, each outstanding Award, as determined by the Plan Administrator in its sole discretion, may be (i) assumed by the successor corporation (or parent thereof), (ii) canceled and substituted with an Award granted by the successor corporation (or parent thereof), (iii) otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction, or (iv) replaced with a cash retention program of the Company or any successor corporation (or parent thereof) which preserves the spread existing on the unvested Award shares subject to the Award at the time of the Change in Control (the excess of the Fair Market Value of those shares over the aggregate purchase price payable for such shares) and, subject to Section 2.7(c) below, provides for subsequent payout of that spread in accordance with the same exercise/vesting schedule applicable to those unvested Award shares.

(b)To the extent an outstanding Award is not assumed, substituted, continued or replaced in accordance with Section 2.7(a), such Award shall automatically vest in full immediately prior to the effective date of the Change in Control, unless the acceleration of such Award is subject to other

A - 11

limitations imposed by the Plan Administrator at the time of the grant of the Award. The Plan Administrator in its sole discretion shall have the authority to provide that to the extent any such Award, as so accelerated, remains unexercised and outstanding on the effective date of the Change in Control, such Award shall terminate and cease to be outstanding. The holder of such Award shall become entitled to receive, upon consummation of the Change in Control and subject to Section 2.7(c), a lump sum cash payment in an amount equal to the product of (i) number of Common Shares subject to such Award and (ii) the excess of (a) the Fair Market Value per Common Share on the date of the Change in Control over (b) the per share exercise price, base price or purchase price in effect for such Award. However, any such Award shall be subject to cancellation and termination, without cash payment or other consideration due the Award holder, if the Fair Market Value per Common Share on the date of such Change in Control is less than the per share exercise price, base price or purchase price in effect for such Award. Notwithstanding the foregoing, if any Award is subject to a performance-vesting condition tied to the attainment of one or more specified performance goals, and such Award is not to be so assumed, substituted, continued, or replaced, that Award shall vest based on actual performance attainment as of the date of the Change in Control or on a pro-rated basis for time elapsed in the ongoing performance period based on target level, immediately prior to the effective date of the actual Change in Control transaction, and the Common Shares underlying the portion of the Award that vests on such accelerated basis shall be issued in accordance with the applicable Award Agreement, unless such accelerated vesting is precluded by other limitations imposed in the Award Agreement.

(c)The Plan Administrator shall have the authority to provide that any escrow, holdback, earn-out or similar provisions in the definitive agreement effecting the Change in Control shall apply to any cash payment made pursuant to Section 2.7(a) or Section 2.7(b) to the same extent and in the same manner as such provisions apply to a holder of a Common Shares.

(d)Immediately following the consummation of the Change in Control, all outstanding Awards shall terminate and cease to be outstanding, except to the extent assumed by the successor corporation (or parent thereof) or otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction.

(e)In the event of any Change in Control, the Plan Administrator in its sole discretion may determine that all outstanding repurchase or cancellation rights (i) are to be assigned to the successor corporation (or parent thereof) or otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction or (ii) are to be terminated and the Common Shares subject to those terminated rights are to immediately vest in full, unless such accelerated vesting is precluded by limitations imposed by the Plan Administrator at the time the right is issued.

(f)Each Award which is assumed in connection with a Change in Control or otherwise continued in effect shall be appropriately adjusted, immediately after such Change in Control, to apply to the number and class of securities into which the Common Shares subject to that Award would have been converted in consummation of such Change in Control had those shares actually been outstanding at that time. Appropriate adjustments to reflect such Change in Control shall also be made to (i) the exercise or base price or cash consideration payable per share in effect under each outstanding Award, provided the aggregate exercise or base price or cash consideration in effect for such securities shall remain the same, (ii) the maximum number and/or class of securities available for issuance over the remaining term of the Plan, (iii) the maximum number and/or class of securities for which Incentive Options may be granted under the Plan, (iv) the maximum number and/or class of securities for which any one person may be granted Awards under the Plan per calendar year and (v) the number and/or class of securities subject to the Company’s outstanding repurchase rights under the Plan and the repurchase price payable per share.

A - 12

To the extent the actual holders of the Company’s outstanding Common Shares receive cash consideration for their Common Shares in consummation of the Change in Control, the successor corporation may, in connection with the assumption or continuation of the outstanding Awards under the Plan and subject to the Plan Administrator’s approval, substitute, for the securities underlying those assumed Awards, one or more shares of its own common stock with a fair market value equivalent to the cash consideration paid per Common Shares in such Change in Control transaction.

(g)The Plan Administrator shall have the discretion, exercisable either at the time an Award is granted or at any time while an Award remains outstanding, to structure such Award so that the shares subject to such Award will automatically vest on an accelerated basis should the Participant’s Service terminate by reason of an Involuntary Termination within a designated period following the effective date of any Change in Control in which the Award is assumed or otherwise continued in effect and the repurchase rights applicable to those shares do not otherwise terminate.

(h)The portion of any Incentive Option accelerated in connection with a Change in Control shall remain exercisable as an Incentive Option only to the extent the applicable One Hundred Thousand Dollar ($100,000) limitation is not exceeded. To the extent such dollar limitation is exceeded, the accelerated portion of such option shall be exercisable as a Non-Statutory Option under the Federal tax laws.

2.8REPRICING PROGRAMS

The Plan Administrator shall not have the discretionary authority, except pursuant to Section 1.5(g), to (i) implement cancellation/regrant programs pursuant to which outstanding options or share appreciation rights under the Plan are cancelled and new options or share appreciation rights are granted in replacement with a lower exercise or base price per share, (ii) cancel outstanding options or share appreciation rights under the Plan with exercise or base prices per share in excess of the then current Fair Market Value per Common Share for consideration payable in cash or in equity securities of the Company(except in the case of a Change in Control) or (iii) reduce the exercise or base price in effect for outstanding options or share appreciation rights under the Plan, in any case without shareholder approval.

ARTICLE 3

MISCELLANEOUS

3.1DEFERRED COMPENSATION

(a)The Plan Administrator may, in its sole discretion, structure one or more Awards (other than options and share appreciation rights) so that the Participants may be provided with an election to defer the compensation associated with those Awards for federal income tax purposes. Any such deferral opportunity shall comply with all applicable requirements of Code Section 409A.

(b)The Plan Administrator may implement a non-employee Board member retainer fee deferral program under the Plan so as to allow the non-employee Board members the opportunity to elect, prior to the start of each calendar year, to convert the Board and Board committee retainer fees to be earned for such year into restricted share units under the Plan that will defer the issuance of the Common Shares that vest under those restricted share units until a permissible date or event under Code Section 409A. If such program is implemented, the Plan Administrator shall have the authority to

A - 13

establish such rules and procedures as it deems appropriate for the filing of such deferral elections and the designation of the permissible distribution events under Code Section 409A.

(c)To the extent the Company maintains one or more separate non-qualified deferred compensation arrangements which allow the participants the opportunity to make notional investments of their deferred account balances in Common Shares, the Plan Administrator may authorize the share reserve under the Plan to serve as the source of any Common Shares that become payable under those deferred compensation arrangements. In such event, the share reserve under the Plan shall be reduced on a share-for-share basis for each Common Shares issued under the Plan in settlement of the deferred compensation owed under those separate arrangements.

3.2TRANSFERABILITY OF AWARDS

The transferability of Awards granted under the Plan shall be governed by the following provisions:

(a)Incentive Options. During the lifetime of the Participant, Incentive Options shall be exercisable only by the Participant and shall not be assignable or transferable other than by will or the laws of inheritance following the Participant’s death.

(b)Other Awards. All other Awards shall be subject to the same limitation on transfer as Incentive Options, except that the Plan Administrator may structure one or more such Awards so that the Award may be assigned in whole or in part during the Participant’s lifetime to one or more Family Members of the Participant or to a trust established exclusively for the Participant and/or such Family Members, to the extent such assignment is in connection with the Participant’s estate plan or pursuant to a domestic relations order. The assigned portion of an Award may only be exercised (if applicable) by the person or persons who acquire a proprietary interest in the Award pursuant to the assignment. The terms applicable to the assigned portion of the Award shall be the same as those in effect for the Award immediately prior to such assignment and shall be set forth in such documents issued to the assignee as the Plan Administrator may deem appropriate.

(c)Beneficiary Designation. Notwithstanding the foregoing, a Participant may, to the extent permitted by the Plan Administrator, designate one or more persons as the beneficiary or beneficiaries of some or all of his or her outstanding Awards, and those Awards shall, in accordance with such designation and to the extent valid under applicable law, automatically be transferred to such beneficiary or beneficiaries upon the Participant’s death while holding those Awards. Such beneficiary or beneficiaries shall take the transferred Awards subject to all the terms and conditions of the applicable agreement evidencing each such transferred Award, including (without limitation) the limited time period during which the Award may be exercised (if applicable) following the Participant’s death.

3.3SHAREHOLDER RIGHTS

A Participant shall not have any of the rights of a shareholder (including the right to vote or receive dividends) with respect to Common Shares covered by an Award until the Participant becomes the holder of record of such shares. A Participant may be granted the right to receive dividend equivalents under Section 2.5 with respect to one or more outstanding Awards. However, any dividend or dividend equivalent payable in connection with an unvested Award shall not be paid until and unless the underlying Award vests and shall be subject to risk of forfeiture to the same extent as the underlying Award.

Without limiting the generality of the foregoing, the Plan Administrator may, in its sole discretion, permit a Participant to satisfy the foregoing Withholding Tax liability in whole or in part by (A) the delivery of Common Shares previously acquired by such individual (other than in connection with the exercise, issuance, vesting or settlement triggering the Withholding Taxes) with an aggregate Fair Market Value equal to the Withholding Taxes or having the Company withhold, from the Common Shares otherwise issuable upon the issuance, exercise, vesting or settlement of such Award, a portion of those shares with an aggregate Fair Market Value at the time of delivery equal to the Withholding Taxes, in each case at a withholding rate determined by the Plan Administrator but in no event to exceed the maximum statutory rate applicable to the Participant.

3.5SHARE ESCROW/LEGENDS

A - 15

(b)The Compensation Committee shall have the discretionary authority to adopt and implement from time to time such addenda or subplans to the Plan as it may deem necessary in order to bring the Plan into compliance with applicable laws and regulations of any foreign jurisdictions in which Awards are to be made under the Plan and/or to obtain favorable tax treatment in those foreign jurisdictions for the individuals to whom the Awards are made.

(c)Awards may be made under the Plan that involve Common Shares in excess of the number of shares then available for issuance under the Plan, provided no shares shall actually be issued pursuant to those Awards until the number of Common Shares available for issuance under the Plan is sufficiently increased by shareholder approval of an amendment of the Plan authorizing such increase. If such shareholder approval is not obtained within twelve (12) months after the date the first excess Award is made, then all Awards granted on the basis of such excess shares shall terminate and cease to be outstanding.

3.11RECOUPMENT

Participants shall be subject to any clawback, recoupment or other similar policy adopted by the Board as in effect (and as modified) from time to time and Awards and any cash, Common Shares or other property or amounts due, paid or issued to a Participant shall be subject to the terms of such policy, as in effect (and as modified) from time to time.

APPENDIX B

ALPHA AND OMEGA SEMICONDUCTOR LIMITED2018 EMPLOYEE SHARE PURCHASE PLAN

I. PURPOSE OF THE PLAN

This 2018 Employee Share Purchase Plan is intended to promote the interests of Alpha and Omega Semiconductor Limited, a company incorporated and existing under the laws of the Islands of Bermuda, by providing eligible employees with the opportunity to acquire a proprietary interest in the Company.

The Company intends that the Plan qualify as an “employee stock purchase plan” under Code Section 423 for one or more specified offerings made under the Plan. The Company may, however, establish one or more offerings under the Plan that are not designed to comply with the requirements of Code Section 423 but are intended to comply with the tax, securities and other compliance requirements of, and obtain tax and other objectives in, the foreign jurisdictions in which those offerings are conducted in order to allow participants in such offerings to purchase shares in a manner similar to the Plan. Such offerings shall be separate from any offering designed to comply with the Code Section 423 requirements but may be conducted concurrently with any such offering.

The Plan shall serve as the successor to the Company’s Employee Share Purchase Plan (the “Predecessor Plan), and no additional offerings will commence under the Predecessor Plan on or after the Effective Date. All outstanding offerings under the Predecessor Plan, however, shall continue in effect in accordance with their terms, consistent with the Predecessor Plan.

Capitalized terms herein shall have the meanings assigned to such terms in the attached Appendix.

II. ADMINISTRATION OF THE PLAN

The Plan Administrator shall have full authority to interpret and construe any provision of the Plan and to adopt such rules and regulations for administering the Plan as it may deem necessary in order to comply with the requirements of Code Section 423 or other applicable law. Decisions of the Plan Administrator shall be final and binding on all parties having an interest in the Plan.

III. SHARES SUBJECT TO PLAN

A.The shares purchasable under the Plan shall be authorized but unissued or reacquired Common Shares, including Common Shares purchased on the open market. Subject to Section III.B, the number of Common Shares reserved for issuance over the term of the Plan shall not exceed One Million Four Hundred Thirty Thousand (1,430,000) shares.

B.Should any change be made to the Common Shares by reason of any share split, share dividend, recapitalization, combination of shares, exchange of shares, spin-off transaction, extraordinary distribution (whether in cash, securities or other property) or other change affecting the outstanding Common Shares as a class without the Company’s receipt of consideration, or should the value of the outstanding Common Shares be substantially reduced as a result of a spin-off transaction or an extraordinary dividend or distribution, then equitable adjustments shall be made to (i) the maximum number and class of securities issuable under the Plan, (ii) the maximum number and class of securities purchasable per Participant on any

B - 1

one Purchase Date, (iii) the maximum number and class of securities purchasable in total by all Participants on any one Purchase Date and (iv) the number and class of securities and the price per share in effect under each outstanding purchase right. The adjustments shall be made in such manner as the Plan Administrator deems appropriate in order to prevent the dilution or enlargement of benefits thereunder.

IV. OFFERING PERIODS

A.The Plan shall be implemented in one or more offerings. Offerings may be consecutive or overlapping. Each offering shall be in such form and shall contain such terms and conditions as the Plan Administrator shall deem appropriate. The terms and conditions of each offering may vary, and two or more offerings may run concurrently under the Plan, each with its own terms and conditions. In addition, special offerings may be established with respect to entities that are acquired by the Company (or any subsidiary of the Company) or under such other circumstances as the Plan Administrator deems appropriate. In no event, however, shall the terms and conditions of any offering contravene the express limitations and restrictions of the Plan, and to the extent required by Code Section 423, the Participants in each separate offering shall have equal rights and privileges under that offering in accordance with the requirements of Code Section 423(b)(5).

B.Common Shares shall be offered for purchase under each offering through a series of overlapping offering periods until such time as (i) the maximum number of Common Shares available for issuance under the Plan shall have been purchased or (ii) the Plan shall have been sooner terminated.

C.Each offering period shall be of such duration (not to exceed twenty-seven (27) months) as determined by the Plan Administrator prior to the commencement date of such offering period. Until such time as otherwise determined by the Plan Administrator, offering periods will commence on May 15 and November 15 (or if such dates are not Trading Days, then the first Trading day immediately following such dates) and will be of a duration of approximately twenty-four (24) months.

D.Each offering period shall consist of one or more successive Purchase Intervals as determined by the Plan Administrator prior to the commencement of such offering period. Until such time as otherwise determined by the Plan Administrator, Purchase Intervals will commence on May 15 and November 15 each year (or if such dates are not Trading Days, then the first Trading Day immediately following such dates) and end on November 14 and May 14, respectively (or if such dates are not Trading Days, then the immediately preceding Trading Day).

E.Should the Fair Market Value per Common Share on any Purchase Date within a particular offering period be less than the Fair Market Value per Common Share on the start date of that offering period, then the individuals participating in such offering period shall, immediately after the purchase of Common Shares on their behalf on such Purchase Date, be transferred from that offering period and automatically enrolled in the next offering period commencing on the next business day following such Purchase Date, provided and only if the Fair Market Value per Common Share on the start date of that new offering period is lower than the Fair Market Value per Common Share on the start date of the offering period in which they were currently enrolled.

F.The terms and conditions of each offering period may vary, and two or more offerings periods may run concurrently under the Plan, each with its own terms and conditions. In addition, special offering periods may be established with respect to entities that are acquired by the Company (or any subsidiary of the Company) or under such other circumstances as the Plan Administrator deems appropriate. In no event, however, shall the terms and conditions of any offering period contravene the express limitations and restrictions of the Plan, and to the extent required by Code Section 423, the Participants in each separate

B - 2

offering shall have equal rights and privileges under that offering in accordance with the requirements of Code Section 423(b)(5).

V. ELIGIBILITY

A.Purchase rights may be granted under the Plan only to Employees of the Company or an Affiliate. Unless otherwise determined by the Plan Administrator for an offering, each individual who is an Eligible Employee on the start date of any offering period under the Plan may enter that offering period on such start date. However, no Eligible Employee may participate in more than one offering period at any one time.

B.The date an individual enters an offering period shall be designated his or her Entry Date for purposes of that offering period.

C.Except as otherwise provided in Section IV.E above, an Eligible Employee must, in order to participate in the Plan for a particular offering period, complete and timely submit the enrollment forms prescribed by the Plan Administrator (which may include accessing the website designated by the Company and electronically completing and submitting the enrollment forms) and file such forms with the Plan Administrator (or its designate) on or before his or her scheduled Entry Date. However, unless sooner enrolled in the Plan in accordance with the foregoing, any Participant enrolled in any offering period outstanding under the Predecessor Plan on the Effective Date shall automatically, following the completion of that offering period, be enrolled upon the same terms and conditions in effect for that offering period, including the authorized rate of payroll deduction, on the start date of the first offering period under the Plan thereafter that incorporates those same terms and conditions.

VI. PAYROLL DEDUCTIONS

A.The payroll deduction authorized by the Participant for purposes of acquiring Common Shares during an offering period may be any multiple of one percent (1%) of the Cash Earnings or Base Salary (as determined by the Plan Administrator prior to the start of the offering period) paid to the Participant during each Purchase Interval within that offering period, up to a maximum of fifteen percent (15%). The deduction rate so authorized shall continue in effect throughout the offering period, except to the extent such rate is changed in accordance with the following guidelines:

(i)The Participant may, at any time during the offering period, reduce his or her rate of payroll deduction to become effective as soon as possible after filing the appropriate form with the Plan Administrator. Unless otherwise determined by the Plan Administrator for an offering, the Participant may not, however, effect more than one (1) such reduction per Purchase Interval.

(ii)The Participant may, prior to the commencement of any new Purchase Interval within the offering period or prior to the start date of any new offering period, increase the rate of his or her payroll deduction by filing the appropriate form with the Plan Administrator. The new rate (which may not exceed the maximum payroll deduction percentage in effect for that offering period) shall become effective on the start date of the first Purchase Interval or first offering period (if earlier) following the filing of such form.

(iii)The Participant may at any time reduce his or her rate of payroll deduction to 0%. Such reduction shall become effective as soon as administratively practicable following the filing of the appropriate form with the Plan Administrator. The Participant’s

B - 3

existing payroll deductions for the Purchase Interval in which such reduction occurs shall be applied to the purchase of Common Shares on the next scheduled Purchase Date.

B.Payroll deductions shall begin on the first pay day administratively feasible following the Participant’s Entry Date and shall (unless sooner terminated by the Participant) continue through the pay day ending with or immediately prior to the last day of that offering period. The amounts so collected shall be credited to the Participant’s book account under the Plan, but no interest shall be paid on the balance from time to time outstanding in such account unless otherwise required by applicable law. The amounts collected from the Participant shall not be required to be held in any segregated account or trust fund and may be commingled with the general assets of the Company and used for general corporate purposes unless otherwise required by applicable law.

C.Payroll deductions (together with any permitted contributions) shall automatically cease upon the termination of the Participant’s purchase right in accordance with the provisions of the Plan.

D.The Plan Administrator may permit Employees in one or more offerings to contribute to the Plan by means other than payroll deductions.

E.The Participant’s acquisition of Common Shares under the Plan on any Purchase Date shall neither limit nor require the Participant’s acquisition of Common Shares on any subsequent Purchase Date, whether within the same or a different offering period.

VII. PURCHASE RIGHTS

A.Grant of Purchase Rights. A Participant shall be granted a separate purchase right for each offering period in which he or she is enrolled. The purchase right shall be granted on the Participant’s Entry Date and shall provide the Participant with the right to purchase Common Shares, in a series of one or more successive installments during that offering period, upon the terms set forth below.

Under no circumstances shall purchase rights be granted under the Plan to any Eligible Employee if such individual would, immediately after the grant, own (within the meaning of Code Section 424(d)) or hold outstanding options or other rights to purchase, shares possessing five percent (5%) or more of the total combined voting power or value of all classes of shares of the Company or any Affiliate.

B.Exercise of the Purchase Right. Each purchase right shall be automatically exercised on each successive Purchase Date within the offering period, and Common Shares shall accordingly be purchased on behalf of each Participant on each such Purchase Date. The purchase shall be effected by applying the Participant’s payroll deductions (or, to the extent applicable, his or her lump sum contribution) for the Purchase Interval ending on such Purchase Date to the purchase of whole Common Shares at the purchase price in effect for the Participant for that Purchase Date.

C.Purchase Price. The purchase price per share at which Common Shares will be purchased on the Participant’s behalf on each Purchase Date within the particular offering period in which he or she is enrolled shall be determined by the Plan Administrator and shall not be less than eighty-five percent (85%) of the lower of (i) the Fair Market Value per Common Share on the Participant’s Entry Date or (ii) the Fair Market Value per Common Share on that Purchase Date. Unless such time as otherwise determined by the Plan Administrator the purchase price per share on any Purchase Date shall be equal to eighty-five percent (85%) of the lower of (i) the Fair Market Value per Common Share on the Participant’s Entry Date or (ii) the Fair Market Value per Common Share on that Purchase Date.

B - 4

D.Number of Purchasable Shares. The number of Common Shares purchasable by a Participant on each Purchase Date during the particular offering period in which he or she is enrolled shall be the number of whole shares obtained by dividing the amount collected from the Participant through payroll deductions during the Purchase Interval ending with that Purchase Date (or, to the extent applicable, his or her lump sum contributions) by the purchase price in effect for the Participant for that Purchase Date. However, the maximum number of Common Shares purchasable per Participant on any one Purchase Date within such offering period shall not exceed 875 shares and the maximum number of Common Shares purchasable in total by all Participants on any one Purchase Date within such offering period shall not exceed 200,000 shares, with each such limitation subject to periodic adjustments in the event of certain changes in the Company’s capitalization. The Plan Administrator shall have the discretionary authority, exercisable prior to the start of any offering period under the Plan, to increase or decrease the limitations to be in effect for the number of shares purchasable per Participant and in total by all Participants on each Purchase Date within that offering period.

E.Excess Payroll Deductions. Any payroll deductions (or contributions) not applied to the purchase of Common Shares on any Purchase Date because they are not sufficient to purchase a whole Common Share or by reason of the limitation on the maximum number of shares purchasable per Participant or in total by all Participants on the Purchase Date shall be promptly refunded.

F.Suspension of Payroll Deductions. In the event that a Participant is, by reason of the accrual limitations in Article VIII, precluded from purchasing additional Common Shares on one or more Purchase Dates during the offering period in which he or she is enrolled, then no further payroll deductions (or contributions) shall be collected from such Participant with respect to those Purchase Dates. The suspension of such deductions (or contributions) shall not terminate the Participant’s purchase right for the offering period in which he or she is enrolled, and payroll deductions (or, to the extent applicable, contributions) shall automatically resume on behalf of such Participant once he or she is again able to purchase shares during that offering period in compliance with the accrual limitations of Article VIII.

G.Withdrawal from Offering Period. The following provisions shall govern the Participant’s withdrawal from an offering period:

(i)A Participant may withdraw from the offering period in which he or she is enrolled at any time prior to the next scheduled Purchase Date by filing the appropriate form with the Plan Administrator (or its designate), and no further payroll deductions (or contributions) shall be collected from the Participant with respect to that offering period. Any payroll deductions (or contributions) collected during the Purchase Interval in which such withdrawal occurs shall, at the Participant’s election, be immediately refunded or held for the purchase of shares on the next Purchase Date. If no such election is made at the time of such withdrawal, then the payroll deductions (or contributions) collected from the Participant during the Purchase Interval in which such withdrawal occurs shall be refunded as soon as possible.

(ii)The Participant’s withdrawal from a particular offering period shall be irrevocable, and the Participant may not subsequently rejoin that offering period at a later date. In order to resume participation in any subsequent offering period, such individual must re-enroll in the Plan (by making a timely filing of the prescribed enrollment forms) on or before his or her scheduled Entry Date into that offering period.

B - 5

H.Termination of Purchase Right. The following provisions shall govern the termination of outstanding purchase rights:

(i)Should the Participant cease to remain an Eligible Employee for any reason (including death, disability or change in status) while his or her purchase right remains outstanding, then that purchase right shall immediately terminate, and all of the Participant’s payroll deductions (or, to the extent applicable, his or her lump sum contributions) for the Purchase Interval in which the purchase right so terminates shall be immediately refunded.

(ii)However, should the Participant cease to remain in active service by reason of an approved unpaid leave of absence, then the Participant shall have the right, exercisable up until the last business day of the Purchase Interval in which such leave commences, to (a) withdraw all the payroll deductions (or contributions) collected to date on his or her behalf for that Purchase Interval or (b) have such funds held for the purchase of shares on his or her behalf on the next scheduled Purchase Date. Unless otherwise determined by the Plan Administrator for one or more offerings, in no event, however, shall any further payroll deductions be collected on the Participant’s behalf during such leave. Upon the Participant’s return to active service (x) within three (3) months following the commencement of such leave or (y) prior to the expiration of any longer period for which such Participant has a right to reemployment with the Company (or an Affiliate) provided by statute or contract, his or her payroll deductions under the Plan shall automatically resume (and the Participant may resume contributions to the extent permitted) at the rate in effect at the time the leave began, unless the Participant withdraws from the Plan prior to his or her return. Unless otherwise determined by the Plan Administrator for one or more offerings, an individual who returns to active employment following a leave of absence that exceeds in duration the applicable (x) or (y) time period will be treated as a new Employee for purposes of subsequent participation in the Plan and must accordingly re-enroll in the Plan (by making a timely filing of the prescribed enrollment forms) on or before his or her scheduled Entry Date into the offering period.

I.Change in Control. Each outstanding purchase right shall automatically be exercised, immediately prior to the effective date of any Change in Control, by applying the payroll deductions of each Participant (or, to the extent applicable, his or her lump sum contributions) for the Purchase Interval in which such Change in Control occurs to the purchase of whole Common Shares at the purchase price per share in effect for that Purchase Interval. However, any applicable limitation on the number of Common Shares purchasable per Participant shall continue to apply to any such purchase, but not the limitation applicable to the maximum number of Common Shares purchasable in total by all Participants on any one Purchase Date.

The Company shall use its best efforts to provide at least ten (10) days’ prior written notice of the occurrence of any Change in Control, and the Participants shall, following the receipt of such notice, have the right to terminate their outstanding purchase rights prior to the effective date of the Change in Control.

J.Proration of Purchase Rights. Should the total number of Common Shares to be purchased pursuant to outstanding purchase rights on any particular date exceed the number of shares then available for issuance under the Plan, the Plan Administrator shall make a pro-rata allocation of the available shares on a uniform and nondiscriminatory basis, and the payroll deductions of each Participant, to the extent in excess of the aggregate purchase price payable for the Common Shares pro-rated to such individual, shall be refunded.

B - 6

K.ESPP Brokerage Account. The Plan Administrator shall have the discretionary authority to require that the shares purchased on behalf of each Participant be deposited directly into a brokerage account which the Company shall establish for the Participant at a Company-designated brokerage firm. The account will be known as the ESPP Brokerage Account, and any shares deposited in the Participant’s ESPP Broker Account must remain in that account until the earliest to occur of (i) the date those shares are to be sold or transferred by gift, (ii) the date on which the requisite holding period necessary to avoid a disqualifying disposition of those shares under the federal tax laws has been satisfied, or (iii) the date of the Participant’s death.

L.Assignability. The purchase right shall be exercisable only by the Participant and shall not be assignable or transferable by the Participant.

M.Shareholder Rights. A Participant shall have no shareholder rights with respect to the shares subject to his or her outstanding purchase right until the shares are purchased on the Participant’s behalf in accordance with the provisions of the Plan and the Participant has become a holder of record of the purchased shares.

N.Withholding Taxes. The Company’s obligation to deliver shares upon exercise of a purchase right under the Plan shall be subject to the satisfaction of all income, employment and payroll taxes, social insurance, social security, national insurance and other contributions, payment on account obligations or other payments required to be collected, withheld or accounted for in connection with the purchase right.

(i)The right to acquire Common Shares under each outstanding purchase right shall accrue in a series of installments on each successive Purchase Date during the offering period in which such right remains outstanding.

(ii)No right to acquire Common Shares under any outstanding purchase right shall accrue to the extent the Participant has already accrued in the same calendar year the right to acquire Common Shares under one or more other purchase rights at a rate equal to Twenty-Five Thousand Dollars ($25,000.00) worth of Common Shares (determined on the basis of the Fair Market Value per share on the date or dates of grant) for each calendar year such rights were at any time outstanding.
