Exhibit 10.4

EXHIBIT A

RECITALS

A. The Board has adopted the Plan for the purpose of retaining the services of selected Employees, non-employee members of the Board or the board of directors of any Parent or Subsidiary and consultants and other independent advisors in the service of the Company (or any Parent or Subsidiary).

B. Optionee is to render valuable services to the Company (or a Parent or Subsidiary), and this Agreement is executed pursuant to, and is intended to carry out the purposes of, the Plan in connection with the Company’s grant of an option to Optionee.

C. All capitalized terms in this Agreement shall have the meaning assigned to them in the attached Appendix.

NOW, THEREFORE, it is hereby agreed as follows:

1. Grant of Option. The Company hereby grants to Optionee, as of the Grant Date, an option to purchase up to the number of Option Shares specified in the Grant Notice. The Option Shares shall be purchasable from time to time during the option term specified in Paragraph 2 at the Exercise Price.

2. Option Term. This option shall have a term of ten (10) years measured from the Grant Date and shall accordingly expire at the close of business on the Expiration Date, unless sooner terminated in accordance with Paragraph 5 or 6.

3. Limited Transferability.

(a) This option, together with the Option Shares during the period prior to exercise, shall be neither transferable nor assignable by Optionee other than by will or the laws of inheritance following Optionee’s death and may be exercised, during Optionee’s lifetime, only by Optionee.

(b) Prior to the date the Company first becomes subject to the reporting requirements of Section 13 or 15(d) of the 1934 Act, this option, together with the underlying unexercised Option Shares, shall not be the subject of any short position, put equivalent position (as such term is defined in Rule 16a-1(h) under the ▇▇▇▇ ▇▇▇) or call equivalent position (as such term is defined Rule 16a-1(b) of the 1934 Act).

(c) Except as otherwise provided in Paragraph 3(a), until the date the Company first becomes subject to the reporting requirements of Section 13 or 15(d) of the 1934 Act, this option, together with the underlying unexercised Option Shares, shall not be the subject of any pledges, gifts, hypothecations or other transfers, other than pursuant to the Company’s repurchase rights or in connection with a Change in Control in which this option, together with all other options outstanding under the Plan at such time, shall terminate and cease to be outstanding.

4. Dates of Exercise. This option shall become exercisable for the Option Shares in one or more installments as specified in the Grant Notice. As the option becomes exercisable for such installments, those installments shall accumulate, and the option shall remain exercisable for the accumulated installments until the Expiration Date or sooner termination of the option term under Paragraph 5 or 6.

5. Cessation of Service. The option term specified in Paragraph 2 shall terminate (and this option shall cease to be outstanding) prior to the Expiration Date should any of the following provisions become applicable:

(a) Should Optionee cease to remain in Service for any reason (other than death, Disability or Misconduct) while this option is outstanding, then Optionee shall have a period of three (3) months (commencing with the date of such cessation of Service) during which to exercise this option, but in no event shall this option be exercisable at any time after the Expiration Date.

(b) Should Optionee die while this option is outstanding, then the personal representative of Optionee’s estate or the person or persons to whom the option is transferred pursuant to Optionee’s will or the laws of inheritance following Optionee’s death shall have the right to exercise this option. Any such right to exercise this option shall lapse, and this option shall cease to be outstanding, upon the earlier of (i) the expiration of the twelve (12)-month period measured from the date of Optionee’s death or (ii) the Expiration Date.

(c) Should Optionee cease Service by reason of Disability while this option is outstanding, then Optionee shall have a period of twelve (12) months (commencing with the date of such cessation of Service) during which to exercise this option. In no event shall this option be exercisable at any time after the Expiration Date.

Note: Exercise of this option on a date later than three (3) months following cessation of Service due to Disability will result in loss of favorable Incentive Option treatment, unless such Disability constitutes Permanent Disability. In the event that Incentive Option treatment is not available, this option will be taxed as a Non-Statutory Option upon exercise.

(d) During the limited period of post-Service exercisability, this option may not be exercised in the aggregate for more than the number of Option Shares in which Optionee is, at the time of Optionee’s cessation of Service, vested pursuant to the Vesting Schedule specified in the Grant Notice or the special vesting acceleration provisions of Paragraph 6. No additional Option Shares shall vest, whether pursuant to the normal vesting schedule specified in the Grant Notice or the special vesting acceleration provisions of Paragraph 6, following Optionee’s cessation of Service, except to the extent (if any) specifically authorized by the Plan Administrator pursuant to an express written agreement with Optionee. Upon the expiration of such limited exercise period or (if earlier) upon the Expiration Date, this option shall terminate and cease to be outstanding for any vested Option Shares for which the option has not been exercised.

(e) Should Optionee’s Service be terminated for Misconduct or should Optionee otherwise engage in Misconduct while this option is outstanding, then this option shall terminate immediately and cease to remain outstanding.

6. Change in Control.

(a) Should a Change in Control occur during Optionee’s period of Service, then the Option Shares at the time subject to this option but not otherwise vested shall automatically vest in full so that this option shall, immediately prior to the effective date of the Change in Control, become exercisable for all of the Option Shares as fully vested shares and may be exercised for any or all of those Option Shares as vested shares. However, the Option Shares shall not vest on such an accelerated basis if and to the extent this option is 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 and the Company’s repurchase rights with respect to the unvested Option Shares purchasable under the Plan are assigned to such successor corporation (or parent thereof) or otherwise continued in effect or such accelerated vesting is otherwise precluded pursuant to the provisions of Paragraph 5(d) above.

(b) Immediately following the Change in Control, this option 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.

(c) If this option is assumed in connection with a Change in Control or otherwise continued in effect, then this option shall be appropriately adjusted, immediately after such Change in Control, to apply to the number and class of securities which would have been issuable to Optionee in consummation of such Change in Control had the option been exercised immediately prior to such Change in Control, and appropriate adjustments shall also be made to the Exercise Price, provided the aggregate Exercise Price shall remain the same. To the extent that 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 this option, substitute one or more shares of its own common stock with a fair market value equivalent to the cash consideration paid per Common Share in such Change in Control.

(d) This Agreement shall not in any 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.

7. Adjustment in Option Shares. In the event of any of the following transactions affecting the outstanding Common Shares as a class without the Company’s receipt of consideration: any share split, share dividend, spin-off transaction, extraordinary distribution (whether in cash, securities or other property), recapitalization, combination of shares, exchange of shares or other similar transaction affecting the Common Shares without the Company’s receipt of consideration or in the event of a substantial reduction to the value of the outstanding Common Shares as a result of a spin-off transaction or extraordinary distribution, then equitable adjustments shall be made to (i) the total number and/or class of securities subject to this option and (ii) the Exercise Price. The adjustments shall be made by the Plan Administrator in such manner as the Plan Administrator deems appropriate in order to reflect such change, and those adjustments shall be final, binding and conclusive.

8. Shareholder Rights. The holder of this option shall not have any shareholder rights with respect to the Option Shares until such person shall have exercised the option, paid the Exercise Price and become the record holder of the purchased shares.

9. Manner of Exercising Option.

(a) In order to exercise this option with respect to all or any part of the Option Shares for which this option is at the time exercisable, Optionee (or any other person or persons exercising the option) must take the following actions:

(i) Execute and deliver to the Company a Purchase Agreement for the Option Shares for which the option is exercised.

(ii) Pay the aggregate Exercise Price for the purchased shares in one or more of the following forms:

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

(B) a promissory note payable to the Company, but only to the extent authorized by the Plan Administrator in accordance with Paragraph 14.

Should the Common Shares be registered under Section 12 of the 1934 Act at the time the option is exercised, then the Exercise Price may also be paid as follows:

(C) in Common Shares held by Optionee (or any other person or persons exercising the option) for the period (if any) necessary to avoid a charge to the Company’s earnings for financial reporting purposes and valued at Fair Market Value on the Exercise Date; or

(D) to the extent the option is exercised for vested Option Shares, through a special sale and remittance procedure pursuant to which Optionee (or any other person or persons exercising the option) shall concurrently provide irrevocable instructions (a) to a brokerage firm (reasonably satisfactory to the Company for purposes of administering such procedure in compliance with any applicable pre-clearance or pre-notification requirements) 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) to 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 the sale and remittance procedure is utilized in connection with the option exercise, payment of the Exercise Price must accompany the Purchase Agreement delivered to the Company in connection with the option exercise.

(iii) Furnish to the Company appropriate documentation that the person or persons exercising the option (if other than Optionee) have the right to exercise this option.

(iv) Execute and deliver to the Company such written representations as may be requested by the Company in order for it to comply with the applicable requirements of applicable securities laws.

(v) Make appropriate arrangements with the Company (or Parent or Subsidiary employing or retaining Optionee) for the satisfaction of all applicable income and employment tax withholding requirements applicable to the option exercise.

(b) As soon as practical after the Exercise Date, the Company shall issue to or on behalf of Optionee (or any other person or persons exercising this option) a certificate for the purchased Option Shares, with the appropriate legends affixed thereto.

10. REPURCHASE RIGHTS. ALL OPTION SHARES ACQUIRED UPON THE EXERCISE OF THIS OPTION SHALL BE SUBJECT TO CERTAIN RIGHTS OF THE COMPANY AND ITS ASSIGNS TO REPURCHASE THOSE SHARES IN ACCORDANCE WITH THE TERMS SPECIFIED IN THE PURCHASE AGREEMENT.

11. Compliance with Laws and Regulations.

(a) The exercise of this option and the issuance of the Option Shares upon such exercise shall be subject to compliance by the Company and Optionee with all applicable requirements of law relating thereto and with all applicable regulations of any stock exchange on which the Common Shares may be listed for trading at the time of such exercise and issuance.

(b) The inability of the Company to obtain approval from any regulatory body having authority deemed by the Company to be necessary to the lawful issuance and sale of any Common Shares pursuant to this option shall relieve the Company of any liability with respect to the non-issuance or sale of the Common Shares as to which such approval shall not have been obtained. The Company, however, shall use its best efforts to obtain all such approvals.

12. Successors and Assigns. Except to the extent otherwise provided in Paragraphs 3 and 6, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the Company and its successors and assigns and Optionee, Optionee’s assigns and the legal representatives, heirs and legatees of Optionee’s estate.

13. Notices. Any notice required to be given or delivered to the Company under the terms of this Agreement shall be in writing and addressed to the Company at its principal corporate offices. Any notice required to be given or delivered to Optionee shall be in writing and addressed to Optionee at the address indicated below Optionee’s signature line on the Grant Notice. All notices shall be deemed effective upon personal delivery or upon deposit in the U.S. mail, postage prepaid and properly addressed to the party to be notified.

14. Financing. The Plan Administrator may, in its absolute discretion and without any obligation to do so, permit Optionee to pay the Exercise Price for the purchased Option Shares by delivering a full-recourse promissory note bearing interest at a market rate and secured by those Option Shares; provided, however, that if Optionee is a consultant, the note must be secured by collateral in addition to the purchased Option Shares. The payment schedule in effect for any such promissory note shall be established by the Plan Administrator in its sole discretion.

15. Construction. This Agreement and the option evidenced hereby are made and granted pursuant to the Plan and are in all respects limited by and subject to the terms of the Plan. All decisions of the Plan Administrator with respect to any question or issue arising under the Plan or this Agreement shall be conclusive and binding on all persons having an interest in this option.

16. Governing Law. The interpretation, performance and enforcement of this Agreement shall be governed by the laws of State of California without resort to that State’s conflict-of-laws rules.

17. Shareholder Approval. If the Option Shares covered by this Agreement exceed, as of the Grant Date, the number of Common Shares which may be issued under the Plan as last approved by the shareholders, then this option shall be void with respect to such excess shares, unless shareholder approval of an amendment sufficiently increasing the number of Common Shares issuable under the Plan is obtained in accordance with the provisions of the Plan.

18. Additional Terms Applicable to an Incentive Option. In the event this option is designated an Incentive Option in the Grant Notice, the following terms and conditions shall also apply to the grant:

(a) This option shall cease to qualify for favorable tax treatment as an Incentive Option if (and to the extent) this option is exercised for one or more Option Shares: (i) more than three (3) months after the date Optionee ceases to be an Employee for any reason other than death or Permanent Disability or (ii) more than twelve (12) months after the date Optionee ceases to be an Employee by reason of Permanent Disability.

(b) This option shall not become exercisable in the calendar year in which granted if (and to the extent) the aggregate Fair Market Value (determined at the Grant Date) of the Common Shares for which this option would otherwise first become exercisable in such calendar year would, when added to the aggregate value (determined as of the respective date or dates of grant) of the Common Shares and any other securities for which one or more other Incentive Options granted to Optionee prior to the Grant Date (whether under the Plan or any other option plan of the Company or any Parent or Subsidiary) first become exercisable during the same calendar year, exceed One Hundred Thousand Dollars ($100,000) in the aggregate. To the extent the exercisability of this option is deferred by reason of the foregoing limitation, the deferred portion shall become exercisable in the first calendar year or years thereafter in which the One Hundred Thousand Dollar ($100,000) limitation of this Paragraph 18(b) would not be contravened, but such deferral shall in all events end immediately prior to the effective date of a Change in Control in which this option is not to be assumed or otherwise continued in effect, whereupon the option shall become immediately exercisable as a Non-Statutory Option for the deferred portion of the Option Shares.

(c) Should Optionee hold, in addition to this option, one or more other options to purchase Common Shares which become exercisable for the first time in the same calendar year as this option, then for purposes of the foregoing limitations on the exercisability of such options as Incentive Options, this option and each of those other options shall be deemed to 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.

ADDENDUM

SHARE OPTION AGREEMENT

The following provisions are hereby incorporated into, and are hereby made a part of, that certain Share Option Agreement (the “Option Agreement”) by and between Alpha and Omega Semiconductor Limited (the “Company”) and (“Optionee”) evidencing the Share Option (the “Option”) granted on this date to Optionee under the terms of the Company’s 2009 Share Option/Share Issuance Plan, and such provisions shall be effective immediately. All capitalized terms in this Addendum, to the extent not otherwise defined herein, shall have the meanings assigned to them in the Option Agreement.

INVOLUNTARY TERMINATION FOLLOWING

A CHANGE IN CONTROL

1. If the Option is to be assumed by the successor corporation (or the parent thereof) in connection with a Change in Control or is otherwise to be continued in full force and effect pursuant to the terms of the Change in Control transaction, then none of the Option Shares shall, in accordance with Paragraph 6 of the Option Agreement, vest on an accelerated basis upon the occurrence of that Change in Control, and Optionee shall accordingly continue, over his or her period of Service following the Change in Control, to vest in the Option Shares in one or more installments in accordance with the provisions of the Option Agreement. However, upon an Involuntary Termination of Optionee’s Service within eighteen (18) months following such Change in Control, all the Option Shares at the time subject to the Option shall automatically vest in full on an accelerated basis so that the Option shall immediately become exercisable for all the Option Shares as fully-vested shares and may be exercised for any or all of those Option Shares as vested shares. The Option shall remain so exercisable until the earlier of (i) the Expiration Date or (ii) the expiration of the one (1)-year period measured from the date of the Involuntary Termination.

2. For purposes of this Addendum, an Involuntary Termination shall mean the termination of Optionee’s Service by reason of:

(a) Optionee’s involuntary dismissal or discharge by the Company for reasons other than for Misconduct, or

(b) Optionee’s voluntary resignation following (A) a change in Optionee’s position with the Company (or Parent or Subsidiary employing Optionee) which materially reduces Optionee’s duties and responsibilities or the level of management to which he or she reports, (B) a reduction in Optionee’s level of compensation (including base salary, fringe benefits and target bonus under any corporate-performance based incentive programs) by more than fifteen percent (15%) or (C) a relocation of Optionee’s place of employment by more than fifty (50) miles, provided and only if such change, reduction or relocation is effected by the Company without Optionee’s consent.

3. The provisions of Paragraph 1 of this Addendum shall govern the period for which the Option is to remain exercisable following the Involuntary Termination of Optionee’s Service within eighteen (18) months after the Change in Control and shall supersede any provisions to the contrary in Paragraph 5 of the Option Agreement. The provisions of this Addendum shall also supersede any provisions to the contrary in Paragraph 18 of the Option Agreement concerning the deferred exercisability of the Option.

IN WITNESS WHEREOF, Alpha and Omega Semiconductor Limited has caused this Addendum to be executed by its duly-authorized officer as of the Effective Date specified below.

CODE SECTION 409A WAIVER AND RELEASE

THIS WAIVER AND RELEASE made as of this day of , 20 by , the holder of a share Option under the Company’s 2009 Share Option/Share Issuance Plan.

All capitalized terms in this Waiver shall have the meaning assigned to them in the attached Appendix.

Optionee hereby agrees and acknowledges that the Company’s Board has taken reasonable steps to value the Common Shares and to set the Exercise Price at the Fair Market Value per Common Share on the Grant Date so that the Option will not be treated as an item of deferred compensation subject to Code Section 409A. However, because the Common Shares are not readily tradable on an established securities market, there can be no assurance that the Exercise Price is at least equal to the Fair Market Value per Common Share on the Grant Date. Were the Internal Revenue Service to conclude that the Exercise Price is in fact less than such Fair Market Value and that the Option is accordingly subject to Code Section 409A, then Optionee would be subject the following adverse tax consequences:

(i) As the Option vests in accordance with the Vesting Schedule, Optionee would immediately recognize taxable income for federal income tax purposes equal to the amount by which the Fair Market Value of the Option Shares which vest at that time exceeds the Exercise Price payable for those shares. The Company would also have to collect from Optionee the federal income and employment taxes which must be withheld on that income. Taxation would occur in this manner even though the Option remains unexercised.

(ii) Optionee may also be subject to additional income taxation and withholding taxes on any subsequent increases to the Fair Market Value of the Option Shares purchasable under the vested Option until the Option is exercised or cancelled as to those Option Shares.

(iii) In addition to normal income taxes payable as the Option vests, Optionee would also be subject to an additional tax penalty equal to 20% of the amount of income Optionee recognizes under Code Section 409A when the Option vests and may also be subject to such penalty as the underlying Option Shares subsequently increase in Fair Market Value over the period the Option continues to remain outstanding.

(iv) There will also be interest penalties if the resulting taxes are not paid on a timely basis.

Optionee hereby further agrees and acknowledges that Optionee will incur the same tax consequences, including (without limitation) a second 20% penalty tax, under California income tax laws if Optionee is a resident of the State of California or is otherwise subject to California income taxation. If the Optionee is a resident of any other State, he or she accepts the risk of any unfavorable tax consequences under the laws of that State applicable to options granted with an Exercise Price less than the Fair Market Value of the Option Shares on the Grant Date.

Optionee hereby agrees to bear the entire risk of such adverse federal and State tax consequences in the event the Option is deemed to be subject to Code Section 409A and hereby knowingly and voluntarily, in consideration for the grant of the Option, waives and releases any and all claims or causes of action that Optionee might otherwise have against the Company and/or its Board, officers, employees or stockholders arising from or relating to the tax treatment of the Option under Code Section 409A and the corresponding provisions of any applicable State income tax laws (including, without limitation, California income tax laws) and shall not seek any indemnification or other recovery of damages against the Company and/or its Board, officers, employees or stockholders with respect to any adverse federal and State tax consequences or other related costs and expenses Optionee may in fact incur under Code Section 409A (or the corresponding provisions of State income tax laws) as a result of the Option.

IN WITNESS WHEREOF, the undersigned Optionee has executed this Waiver on the date and year first indicated above.

(b) Payment. Concurrently with the delivery of this Agreement to the Company, Optionee shall pay the Exercise Price for the Purchased Shares in accordance with the provisions of the Option Agreement and shall deliver whatever additional documents may be required by the Option Agreement as a condition for exercise, together with a duly-executed blank Assignment Separate from Certificate (in the form attached hereto as Exhibit I) with respect to the Purchased Shares.

2. SECURITIES LAW COMPLIANCE

(a) Restricted Securities. The Purchased Shares have not been registered under the 1933 Act and are being issued to Optionee in reliance upon the exemption from such registration provided by SEC Rule 701 for share issuances under compensatory benefit plans such as the Plan. Optionee hereby confirms that Optionee has been informed that the Purchased Shares are restricted securities under the 1933 Act and may not be resold or transferred unless the Purchased Shares are first registered under the Federal securities laws or unless an exemption from such registration is available. Accordingly, Optionee hereby acknowledges that Optionee is acquiring the Purchased Shares for investment purposes only and not with a view to resale and is prepared to hold the Purchased Shares for an indefinite period and that Optionee is aware that SEC Rule 144 issued under the 1933 Act which exempts certain resales of unrestricted securities is not presently available to exempt the resale of the Purchased Shares from the registration requirements of the 1933 Act.

(b) Restrictions on Disposition of Purchased Shares. Optionee shall make no disposition of the Purchased Shares (other than a Permitted Transfer) unless and until there is compliance with all of the following requirements:

(A) Optionee shall have provided the Company with a written summary of the terms and conditions of the proposed disposition.

(B) Optionee shall have complied with all requirements of this Agreement applicable to the disposition of the Purchased Shares.

(C) Optionee shall have provided the Company with written assurances, in form and substance satisfactory to the Company, that (a) the proposed disposition does not require registration of the Purchased Shares under the 1933 Act or (b) all appropriate action necessary for compliance with the registration requirements of the 1933 Act or any exemption from registration available under the 1933 Act (including Rule 144) has been taken.

The Company shall not be required (i) to transfer on its books any Purchased Shares which have been sold or transferred in violation of the provisions of this Agreement or (ii) to treat as the owner of the Purchased Shares, or otherwise to accord voting, dividend or liquidation rights to, any transferee to whom the Purchased Shares have been transferred in contravention of this Agreement.

(c) Restrictive Legends. The share certificates for the Purchased Shares shall be endorsed with one or more of the following restrictive legends:

“The shares represented by this certificate have not been registered under the Securities Act of 1933. The shares may not be sold or offered for sale in the absence of (a) an effective registration statement for the shares under such Act, (b) a ‘no action’ letter of the Securities and Exchange Commission with respect to such sale or offer or (c) satisfactory assurances to the Company that registration under such Act is not required with respect to such sale or offer.”

“The shares represented by this certificate are subject to certain repurchase rights and rights of first refusal granted to the Company and accordingly may not be sold, assigned, transferred, encumbered, or in any manner disposed of except in conformity with the terms of a written agreement dated , 20 between the Company and the registered holder of the shares (or the predecessor in interest to the shares). A copy of such agreement is maintained at the Company’s principal corporate offices.”

3. TRANSFER RESTRICTIONS

(a) Restriction on Transfer. Except for any Permitted Transfer, Optionee shall not transfer, assign, encumber or otherwise dispose of any of the Purchased Shares which are subject to the Repurchase Right. In addition, Purchased Shares which are released from the Repurchase Right shall not be transferred, assigned, encumbered or otherwise disposed of in contravention of the First Refusal Right or the Market Stand-Off.

(b) Transferee Obligations. Each person (other than the Company) to whom the Purchased Shares are transferred by means of a Permitted Transfer must, as a condition precedent to the validity of such transfer, acknowledge in writing to the Company that such person is bound by the provisions of this Agreement and that the transferred shares are subject to (i) the Repurchase Right, (ii) the First Refusal Right and (iii) the Market Stand-Off, to the same extent such shares would be so subject if retained by Optionee.

(i) In connection with any underwritten public offering by the Company of its equity securities pursuant to an effective registration statement filed under the 1933 Act, including the Company’s initial public offering, Owner shall not sell, make any short sale of, loan, hypothecate, pledge, grant any option for the purchase of, or otherwise dispose or transfer for value or otherwise agree to engage in any of the foregoing transactions with respect to, any Purchased Shares without the prior written consent of the Company or its underwriters. Such restriction (the “Market Stand-Off”) shall be in effect for such period of time from and after the effective date of the final prospectus for the offering as may be requested by the Company or such underwriters. In no event, however, shall such period exceed the greater of (a) one hundred eighty (180) days or (b) if required by such underwriters, such longer period of time as is necessary to enable the underwriters to issue a research report, analyst recommendation or opinion in accordance with the then-applicable rules and regulations of the Financial Regulatory Authority, Inc. and the applicable Stock Exchange, but in no event in excess of two hundred ten (210) days following the effective date of the registration statement relating to such offering. The Market Stand-Off shall in no event be applicable to any underwritten public offering effected more than two (2) years after the effective date of the Company’s initial public offering.

(ii) Owner shall be subject to the Market Stand-Off provided and only if the officers and directors of the Company are also subject to similar restrictions.

(iii) Any new, substituted or additional securities which are by reason of any Recapitalization or Reorganization distributed with respect to the Purchased Shares shall be immediately subject to the Market Stand-Off, to the same extent the Purchased Shares are at such time covered by such provisions.

(iv) In order to enforce the Market Stand-Off, the Company may impose stop-transfer instructions with respect to the Purchased Shares until the end of the applicable stand-off period.

4. REPURCHASE RIGHT

(a) Grant. The Company is hereby granted the right (the “Repurchase Right”), exercisable at any time during the sixty (60)-day period following the date Optionee ceases for any reason to remain in Service or (if later) during the sixty (60)-day period following the execution date of this Agreement, to repurchase at the Repurchase Price any or all of the Purchased Shares in which Optionee is not, at the time of his or her cessation of Service, vested in accordance with the Vesting Schedule applicable to those shares or the special vesting acceleration provisions of Paragraph D.6 of this Agreement (such shares to be hereinafter referred to as the “Unvested Shares”).

(b) Exercise of the Repurchase Right. The Repurchase Right shall be exercisable by written notice delivered to each Owner of the Unvested Shares prior to the expiration of the sixty (60)-day exercise period. The notice shall indicate the number of Unvested Shares to be repurchased, the Repurchase Price to be paid per share and the date on which the repurchase is to be effected, such date to be not more than thirty (30) days after the date of such notice. The certificates representing the Unvested Shares to be repurchased shall be delivered to the Company on the closing date specified for the repurchase. Concurrently with the receipt of such share certificates, the Company shall pay to Owner, in cash or cash equivalents (including the cancellation of any purchase-money indebtedness), an amount equal to the Repurchase Price for the Unvested Shares which are to be repurchased from Owner.

(c) Termination of the Repurchase Right. The Repurchase Right shall terminate with respect to any Unvested Shares for which it is not timely exercised under Paragraph D.2. In addition, the Repurchase Right shall terminate and cease to be exercisable with respect to any and all Purchased Shares in which Optionee vests in accordance with the Vesting Schedule. All Purchased Shares as to which the Repurchase Right lapses shall, however, remain subject to (i) the First Refusal Right and (ii) the Market Stand-Off.

(d) Aggregate Vesting Limitation. If the Option is exercised in more than one increment so that Optionee is a party to one or more other Share Purchase Agreements (the “Prior Purchase Agreements”) which are executed prior to the date of this Agreement, then the total number of Purchased Shares as to which Optionee shall be deemed to have a fully-vested interest under this Agreement and all Prior Purchase Agreements shall not exceed in the aggregate the number of Purchased Shares in which Optionee would otherwise at the time be vested, in accordance with the Vesting Schedule, had all the Purchased Shares (including those acquired under the Prior Purchase Agreements) been acquired exclusively under this Agreement.

(e) Recapitalization. Any new, substituted or additional securities or other property (including cash paid other than as a regular cash dividend) which is by reason of any Recapitalization distributed with respect to the Purchased Shares shall be immediately subject to the Repurchase Right and any escrow requirements hereunder, but only to the extent the Purchased Shares are at the time covered by such right or escrow requirements. Appropriate adjustments to reflect such distribution shall be made to the number and/or class of Purchased Shares subject to this Agreement and to the Repurchase Price per share to be paid upon the exercise of the Repurchase Right in order to reflect the effect of any such Recapitalization upon the Company’s capital structure; provided, however, that the aggregate Repurchase Price shall remain the same.

(f) Change in Control.

(i) The Repurchase Right shall automatically terminate in its entirety, and all the Purchased Shares shall vest in full, immediately prior to the consummation of any Change in Control, except to the extent

the Repurchase Right is to be assigned to the successor entity in such Change in Control or otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction.

(ii) To the extent the Repurchase Right remains in effect following a Change in Control, such right shall apply to any new securities or other property (including any cash payments) received in exchange for the Purchased Shares in consummation of the Change in Control, but only to the extent the Purchased Shares are at the time covered by such right. Appropriate adjustments shall be made to the Repurchase Price per share payable upon exercise of the Repurchase Right to reflect the effect (if any) of the Change in Control upon the Company’s capital structure; provided, however, that the aggregate Repurchase Price shall remain the same. The new securities or other property (including any cash payments) issued or distributed with respect to the Purchased Shares in consummation of the Change in Control shall be immediately deposited in escrow with the Company (or the successor entity) and shall not be released from escrow until Optionee vests in such securities or other property in accordance with the same Vesting Schedule in effect for the Purchased Shares.

5. RIGHT OF FIRST REFUSAL

(a) Grant. The Company is hereby granted the right of first refusal (the “First Refusal Right”), exercisable in connection with any proposed transfer of the Purchased Shares in which Optionee has vested in accordance with the provisions of Article D. For purposes of this Article E, the term “transfer” shall include any sale, assignment, pledge, encumbrance or other disposition of the Purchased Shares intended to be made by Owner, but shall not include any Permitted Transfer.

(b) Notice of Intended Disposition. In the event any Owner of Purchased Shares in which Optionee has vested desires to accept a bona fide third-party offer for the transfer of any or all of such shares (the Purchased Shares subject to such offer to be hereinafter referred to as the “Target Shares”), Owner shall promptly (i) deliver to the Company written notice (the “Disposition Notice”) of the terms of the offer, including the purchase price and the identity of the third-party offeror, and (ii) provide satisfactory proof that the disposition of the Target Shares to such third-party offeror would not be in contravention of the provisions set forth in Articles B and C.

(c) Exercise of the First Refusal Right. The Company shall, for a period of twenty-five (25) days following receipt of the Disposition Notice, have the right to repurchase any or all of the Target Shares subject to the Disposition Notice upon the same terms as those specified therein or upon such other terms (not materially different from those specified in the Disposition Notice) to which Owner consents. Such right shall be exercisable by delivery of written notice (the “Exercise Notice”) to Owner prior to the expiration of the twenty-five (25)-day exercise period. If such right is exercised with respect to all the Target Shares, then the Company shall effect the repurchase of such shares, including payment of the purchase price, not more than five (5) business days after delivery of the Exercise Notice; and at such time the certificates representing the Target Shares shall be delivered to the Company.

Should the purchase price specified in the Disposition Notice be payable in property other than cash or evidences of indebtedness, the Company shall have the right to pay the purchase price in the form of cash equal in amount to the value of such property. If Owner and the Company cannot agree on such cash value within ten (10) days after the Company’s receipt of the Disposition Notice, the valuation shall be made by an appraiser of recognized standing selected by Owner and the Company or, if they cannot agree on an appraiser within twenty (20) days after the Company’s receipt of the Disposition Notice, each shall select an appraiser of recognized standing and the two (2) appraisers shall designate a third appraiser of recognized standing, whose appraisal shall be determinative of such value. The cost of such appraisal shall be shared equally by Owner and the Company. The closing shall then be held on the later of (i) the fifth (5th) business day following delivery of the Exercise Notice or (ii) the fifth (5th) business day after such valuation shall have been made.

(d) Non-Exercise of the First Refusal Right. In the event the Exercise Notice is not given to Owner prior to the expiration of the twenty-five (25)-day exercise period, Owner shall have a period of thirty

(30) days thereafter in which to sell or otherwise dispose of the Target Shares to the third-party offeror identified in the Disposition Notice upon terms (including the purchase price) no more favorable to such third-party offeror than those specified in the Disposition Notice; provided, however, that any such sale or disposition must not be effected in contravention of the provisions of Articles B and C. The third-party offeror shall acquire the Target Shares subject to the First Refusal Right and the provisions and restrictions of Article B and Paragraph C.3, and any subsequent disposition of the acquired shares must be effected in compliance with the terms and conditions of such First Refusal Right and the provisions and restrictions of Article B and Paragraph C.3. In the event Owner does not effect such sale or disposition of the Target Shares within the specified thirty (30)-day period, the First Refusal Right shall continue to be applicable to any subsequent disposition of the Target Shares by Owner until such right lapses.

(e) Partial Exercise of the First Refusal Right. In the event the Company makes a timely exercise of the First Refusal Right with respect to a portion, but not all, of the Target Shares specified in the Disposition Notice, Owner shall have the option, exercisable by written notice to the Company delivered within five (5) business days after Owner’s receipt of the Exercise Notice, to effect the sale of the Target Shares pursuant to either of the following alternatives:

(A) sale or other disposition of all the Target Shares to the third-party offeror identified in the Disposition Notice, but in full compliance with the requirements of Paragraph E.4, as if the Company did not exercise the First Refusal Right; or

(B) sale to the Company of the portion of the Target Shares which the Company has elected to purchase, such sale to be effected in substantial conformity with the provisions of Paragraph E.3. The First Refusal Right shall continue to be applicable to any subsequent disposition of the remaining Target Shares until such right lapses.

Owner’s failure to deliver timely notification to the Company shall be deemed to be an election by Owner to sell the Target Shares pursuant to alternative (i) above.

(f) Recapitalization/Reorganization.

(i) Any new, substituted or additional securities or other property which is by reason of any Recapitalization distributed with respect to the Purchased Shares shall be immediately subject to the First Refusal Right, but only to the extent the Purchased Shares are at the time covered by such right.

(ii) In the event of a Reorganization, the First Refusal Right shall remain in full force and effect and shall apply to the new capital stock or other property received in exchange for the Purchased Shares in consummation of the Reorganization, but only to the extent the Purchased Shares are at the time covered by such right.

(g) Lapse. The First Refusal Right shall lapse upon the earliest to occur of (i) the first date on which shares of the Common Shares are held of record by more than five hundred (500) persons, (ii) a determination made by the Board that a public market exists for the outstanding Common Shares or (iii) a firm commitment underwritten public offering, pursuant to an effective registration statement under the 1933 Act, covering the offer and sale of the Common Shares in the aggregate amount of at least twenty million dollars ($20,000,000). However, the Market Stand-Off shall continue to remain in full force and effect following the lapse of the First Refusal Right.

6. SPECIAL TAX ELECTION

The acquisition of the Purchased Shares may result in adverse tax consequences which may be avoided or mitigated by filing an election under Code Section 83(b). Such election must be filed within thirty (30) days after the date of this Agreement. A description of the tax consequences applicable to the acquisition of the Purchased Shares and the form for making the Code Section 83(b) election are set forth in Exhibit II. OPTIONEE SHOULD CONSULT WITH HIS OR HER TAX ADVISOR TO DETERMINE THE TAX CONSEQUENCES OF ACQUIRING THE PURCHASED SHARES AND THE ADVANTAGES AND DISADVANTAGES OF FILING THE CODE SECTION 83(b)

ELECTION. OPTIONEE ACKNOWLEDGES THAT IT IS OPTIONEE’S SOLE RESPONSIBILITY, AND NOT THE COMPANY’S, TO FILE A TIMELY ELECTION UNDER CODE SECTION 83(b), EVEN IF OPTIONEE REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON HIS OR HER BEHALF.

7. GENERAL PROVISIONS

(a) Assignment. The Company may assign the Repurchase Right and/or the First Refusal Right to any person or entity selected by the Board, including (without limitation) one or more shareholders of the Company.

(b) At Will Employment. Nothing in this Agreement or in the Plan shall confer upon Optionee any right to continue in Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Company (or any Parent or Subsidiary employing or retaining Optionee) or of Optionee, which rights are hereby expressly reserved by each, to terminate Optionee’s Service at any time for any reason, with or without cause.

(c) Notices. Any notice required to be given under this Agreement shall be in writing and shall be deemed effective upon personal delivery or upon deposit in the U.S. mail, registered or certified, postage prepaid and properly addressed to the party entitled to such notice at the address indicated below such party’s signature line on this Agreement or at such other address as such party may designate by ten (10) days advance written notice under this paragraph to all other parties to this Agreement.

(d) No Waiver. The failure of the Company in any instance to exercise the Repurchase Right or the First Refusal Right shall not constitute a waiver of any other repurchase rights and/or rights of first refusal that may subsequently arise under the provisions of this Agreement or any other agreement between the Company and Optionee. No waiver of any breach or condition of this Agreement shall be deemed to be a waiver of any other or subsequent breach or condition, whether of like or different nature.

(e) Cancellation of Shares. If the Company shall make available, at the time and place and in the amount and form provided in this Agreement, the consideration for the Purchased Shares to be repurchased in accordance with the provisions of this Agreement, then from and after such time, the person from whom such shares are to be repurchased shall no longer have any rights as a holder of such shares (other than the right to receive payment of such consideration in accordance with this Agreement). Such shares shall be deemed purchased in accordance with the applicable provisions hereof, and the Company shall be deemed the owner and holder of such shares, whether or not the certificates therefor have been delivered as required by this Agreement.

8. MISCELLANEOUS PROVISIONS

(a) Optionee Undertaking. Optionee hereby agrees to take whatever additional action and execute whatever additional documents the Company may deem necessary or advisable in order to carry out or effect one or more of the obligations or restrictions imposed on either Optionee or the Purchased Shares pursuant to the provisions of this Agreement.

(b) Agreement is Entire Contract. This Agreement constitutes the entire contract between the parties hereto with regard to the subject matter hereof. This Agreement is made pursuant to the provisions of the Plan and shall in all respects be construed in conformity with the terms of the Plan.

(c) Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of State of California without resort to that State’s conflict-of-laws rules.

(d) Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed to be an original, but all of which together shall constitute one and the same instrument.

(e) Successors and Assigns. The provisions of this Agreement shall inure to the benefit of, and be binding upon, the Company and its successors and assigns and upon Optionee, Optionee’s permitted assigns and the legal representatives, heirs and legatees of Optionee’s estate, whether or not any such person shall have become a party to this Agreement and have agreed in writing to join herein and be bound by the terms hereof.

EXHIBIT II

FEDERAL INCOME TAX CONSEQUENCES AND

SECTION 83(B) TAX ELECTION

I. Federal Income Tax Consequences and Section 83(b) Election For Exercise of Non-Statutory Option. If the Purchased Shares are acquired pursuant to the exercise of a Non-Statutory Option, as specified in the Grant Notice, then under Code Section 83, the excess of the Fair Market Value of the Purchased Shares on the date any forfeiture restrictions applicable to such shares lapse over the Exercise Price paid for those shares will be reportable as ordinary income on the lapse date. For this purpose, the term “forfeiture restrictions” includes the right of the Company to repurchase the Purchased Shares pursuant to the Repurchase Right. However, Optionee may elect under Code Section 83(b) to be taxed at the time the Purchased Shares are acquired, rather than when and as such Purchased Shares cease to be subject to such forfeiture restrictions. Such election must be filed with the Internal Revenue Service within thirty (30) days after the date of the Agreement. Even if the Fair Market Value of the Purchased Shares on the date of the Agreement equals the Exercise Price paid (and thus no tax is payable), the election must be made to avoid adverse tax consequences in the future. The form for making this election is attached as part of this exhibit. FAILURE TO MAKE THIS FILING WITHIN THE APPLICABLE THIRTY (30)-DAY PERIOD WILL RESULT IN THE RECOGNITION OF ORDINARY INCOME BY OPTIONEE AS THE FORFEITURE RESTRICTIONS LAPSE.

II. Federal Income Tax Consequences and Conditional Section 83(b) Election For Exercise of Incentive Option. If the Purchased Shares are acquired pursuant to the exercise of an Incentive Option, as specified in the Grant Notice, then the following tax principles shall be applicable to the Purchased Shares:

(i) For regular tax purposes, no taxable income will be recognized at the time the Option is exercised.

(ii) The excess of (a) the Fair Market Value of the Purchased Shares on the date the Option is exercised or (if later) on the date any forfeiture restrictions applicable to the Purchased Shares lapse over (b) the Exercise Price paid for the Purchased Shares will be includible in Optionee’s taxable income for alternative minimum tax purposes.

(iii) If Optionee makes a disqualifying disposition of the Purchased Shares, then Optionee will recognize ordinary income in the year of such disposition equal in amount to the excess of (a) the Fair Market Value of the Purchased Shares on the date the Option is exercised or (if later) on the date any forfeiture restrictions applicable to the Purchased Shares lapse over (b) the Exercise Price paid for the Purchased Shares. Any additional gain recognized upon the disqualifying disposition will be either short-term or long-term capital gain depending upon the period for which the Purchased Shares are held prior to the disposition.

(iv) For purposes of the foregoing, the term “forfeiture restrictions” will include the right of the Company to repurchase the Purchased Shares pursuant to the Repurchase Right. The term “disqualifying disposition” means any sale or other disposition¹ of the Purchased Shares within two (2) years after the Grant Date or within one (1) year after the exercise date of the Option.

(v) The Code Section 83(b) election will be effective in limiting the Optionee’s alternative minimum taxable income to the excess of the Fair Market Value of the Purchased Shares at the time the Option is exercised over the Exercise Price paid for those shares.

Page 2 of the attached form for making the election should be filed with any election made in connection with the exercise of an Incentive Option.

Generally, a disposition of shares purchased under an Incentive Option includes any transfer of legal title, including a transfer by sale, exchange or gift, but does not include a transfer to the Optionee’s spouse, a transfer into joint ownership with right of survivorship if Optionee remains one of the joint owners, a pledge, a transfer by bequest or inheritance or certain tax-free exchanges permitted under the Code.

Optionee must retain two (2) copies of the completed form for filing with his or her Federal and state tax returns for the current tax year and an additional copy for his or her records.

The property described in the above Section 83(b) election is comprised of common shares acquired pursuant to the exercise of an incentive Share Option under Section 422 of the Internal Revenue Code (the “Code”).

In the absence of this election, such alternative minimum taxable income would be measured by the spread between the fair market value of the purchased shares and the purchase price which exists on the various lapse dates in effect for the forfeiture restrictions applicable to such shares.

ADDENDUM

SHARE PURCHASE AGREEMENT

The following provisions are hereby incorporated into, and are hereby made a part of, that certain Share Purchase Agreement (the “Purchase Agreement”) by and between Alpha and Omega Semiconductor Limited (the “Company”) and (“Optionee”) evidencing Common Shares purchased on this date by Optionee under the Company’s 2009 Share Option/Share Issuance Plan, and such provisions shall be effective immediately. All capitalized terms in this Addendum, to the extent not otherwise defined herein, shall have the meanings assigned to such terms in the Purchase Agreement.

INVOLUNTARY TERMINATION FOLLOWING

A CHANGE IN CONTROL

1. To the extent the Repurchase Right is assigned to the successor corporation (or parent thereof) in connection with a Change in Control or otherwise continued in full force and effect pursuant to the terms of the Change in Control transaction, no accelerated vesting of the Purchased Shares shall occur upon that Change in Control, and the Repurchase Right shall continue to remain in full force and effect in accordance with the provisions of the Purchase Agreement. Optionee shall, over his or her period of Service following such Change in Control, continue to vest in the Purchased Shares in one or more installments in accordance with the provisions of the Purchase Agreement. However, upon an Involuntary Termination of Optionee’s Service within eighteen (18) months following such Change in Control, the Repurchase Right shall terminate automatically, and all the Purchased Shares shall immediately vest in full at that time. Any unvested escrow account maintained on Optionee’s behalf pursuant to Paragraph D.6 of the Purchase Agreement shall also vest at the time of such Involuntary Termination and shall be paid to Optionee promptly thereafter.

2. For purposes of this Addendum, the following definitions shall be in effect:

An Involuntary Termination shall mean the termination of Optionee’s Service by reason of:

(a) Optionee’s involuntary dismissal or discharge by the Company for reasons other than for Misconduct, or

(b) Optionee’s voluntary resignation following (A) a change in his or her position with the Company (or Parent or Subsidiary employing Optionee) which materially reduces his or her duties and responsibilities or the level of management to which he or she reports, (B) a reduction in Optionee’s level of compensation (including base salary, fringe benefits and target bonus under any corporate-performance based incentive programs) by more than fifteen percent (15%) or (C) a relocation of Optionee’s place of employment by more than fifty (50) miles, provided and only if such change, reduction or relocation is effected by the Company without Optionee’s consent.

Misconduct shall mean the termination of Optionee’s Service by reason of Optionee’s commission of any act of fraud, embezzlement or dishonesty, any unauthorized use or disclosure by Optionee of confidential information or trade secrets of the Company (or any Parent or Subsidiary), or any other intentional misconduct by Optionee adversely affecting the business or affairs of the Company (or any Parent or Subsidiary) in a material manner. The foregoing definition shall not in any way preclude or restrict the right of the Company (or any Parent or Subsidiary) to discharge or dismiss Optionee or any other person in the Service of the Company (or any Parent or Subsidiary) for any other acts or omissions, but such other acts or omissions shall not be deemed, for purposes of the Plan and this Addendum, to constitute grounds for termination for Misconduct.
