DIODES INCORPORATED 2013 EQUITY INCENTIVE PLAN STOCK UNIT AGREEMENT

Participant:

The Plan and

Other Agreements

The text of the Plan is incorporated in this Agreement by reference. You and the Company agree to execute such further instruments and to take such further action as may reasonably be necessary to carry out the intent of this Agreement. Unless otherwise defined in this Agreement, certain capitalized terms used in this Agreement are defined in the Plan.

This Agreement and the Plan constitute the entire understanding between you and the Company regarding this Award of Stock Units. Any prior agreements, commitments or negotiations concerning this Award are superseded.

The Company awards you the number of Stock Units shown on the cover sheet of this Agreement. The Award is subject to the terms and conditions of this Agreement and the Plan. The Company will not issue any Shares if the issuance of such Shares at that time would violate any law or regulation.

This Award will vest according to the Vesting Schedule described in the cover sheet of this Agreement. To the extent a Stock Unit becomes vested and subject to your satisfaction of any tax withholding obligations as discussed below, each vested Stock Unit will entitle you to receive one Share which will be distributed to you on the earliest of (i) a Change in Control, or (ii) the applicable scheduled vesting date set forth in the first sentence of the Vesting Schedule section in the cover sheet to this Agreement. Issuance of such Shares shall be in complete satisfaction of such vested Stock Units. Such settled Stock Units shall be immediately cancelled and no longer outstanding and you shall have no further rights or entitlements related to those settled Stock Units.

You cannot gift, transfer, assign, alienate, pledge, hypothecate, attach, sell, or encumber this Award. If you attempt to do any of these things, this Award will immediately become invalid. You may, however, dispose of this Award in your will or it may be transferred by the laws of descent and distribution. Regardless of any marital property settlement agreement, the Company is not obligated to recognize your spouse’s interest in your Award in any other way.

Termination of

Service – General

If, while the unvested Stock Units are outstanding, your Service terminates for any reason, other than being terminated by the Company for Cause or due to your death or Disability, then the unvested portion of your Stock Units shall be forfeited without consideration and shall immediately expire on your Termination Date.

Termination of

Service for Cause

If your Service is terminated by the Company for Cause or if you commit an act(s) of Cause while the unvested Stock Units are outstanding, as determined by the Committee in its sole discretion, then you shall immediately forfeit all rights to your unvested Stock Units without consideration, and the entire unvested Stock Units shall immediately expire, and any rights, payments and benefits with respect to the unvested Stock Units shall be subject to reduction or recoupment in accordance with applicable Company policies and the Plan. For avoidance of doubt, your Service shall also be deemed to have been terminated for Cause by the Company if, after your Service has otherwise terminated, facts and circumstances are discovered that would have justified a termination for Cause, including, without limitation, your violation of Company policies or breach of confidentiality or other restrictive covenants or conditions that may apply prior to or after your Termination Date.

Termination of

Service due to Death

or Disability

If your Service terminates because of your death or Disability, then the unvested portion of your Stock Units shall continue to vest as provided on the cover sheet of this Agreement.

For purposes of this Award, your Service does not terminate when you go on a bona fide leave of absence that was approved by the Company in writing, if the terms of the leave of absence provide for Service crediting, or when Service crediting is required by applicable law. Your Service terminates in any event when the approved leave of absence ends unless you immediately return to active work.

The Company determines which leaves of absence count for this purpose (along with determining the effect of a leave of absence on vesting of the Award), and when your Service terminates for all purposes under the Plan.

As a holder of Stock Units, you shall have no rights other than those of a general creditor of the Company. Subject to the terms of this Agreement, a holder of outstanding Stock Units has none of the rights and privileges of a stockholder of the Company. Without limiting the generality of the foregoing, a holder of outstanding Stock Units has no right to vote or to receive dividends (if any) on the shares represented by such Stock Units. Subject to the terms and conditions of this Agreement, Stock Units create no fiduciary duty of the Company to you and only represent an unfunded and unsecured contractual obligation of the Company. The Stock Units shall not be treated as property or as a trust fund of any kind.

You, or your estate, shall have no rights as a stockholder of the Company with regard to the Award until you have been issued the applicable Shares by the Company and have satisfied all other conditions specified in the Plan. No adjustment shall be made for cash or stock dividends or other rights for which the record date is prior to the date when such applicable Shares are issued, except as provided in the Plan.

Taxes and

Withholding

You will be solely responsible for payment of any and all applicable taxes, including without limitation any penalties or interest based upon such tax obligations, associated with this Award.

The delivery to you of any Shares underlying vested Stock Units will not be permitted unless and until you have satisfied any withholding or other taxes that may be due. Any such tax withholding obligations may be settled in the Company’s discretion by the Company withholding and retaining a portion of the Shares from the Shares that would otherwise be deliverable to you under the vesting Stock Units as provided in the next two sentences. Such withheld Shares will be applied to pay the withholding obligation by using the aggregate fair market value of the withheld Shares as of the date of settlement. You will be delivered the net amount of vested Shares after the Share withholding has been effected and you will not receive the withheld Shares. The Company will not deliver any fractional number of Shares.

This Award will be administered and interpreted to comply with Code Section 409A. The provisions of the Plan concerning Code Section 409A will apply to this Award to the extent needed.

By signing this Agreement, you agree not to sell, transfer, dispose of, pledge, hypothecate, make any short sale of, or otherwise effect a similar transaction of any Shares acquired under this Award (each a “Sale Prohibition”) at a time when applicable laws, regulations or Company or underwriter trading policies prohibit the sale or disposition of Shares.

The Company shall have the right to designate one or more periods of time, each of which generally will not exceed one hundred eighty (180) days in length (provided however, that such period may be extended in connection with the Company’s release (or announcement of release) of earnings results or other material news or events), and to impose a Sale Prohibition, if the Company determines (in its sole discretion) that such limitation(s) is/are needed in connection with a public offering of Shares or to comply with an underwriter’s request or trading policy, or could in any way facilitate a lessening of any restriction on transfer pursuant to the Securities Act or any state securities laws with respect to any issuance of securities by the Company, facilitate the registration or qualification of any securities by the Company under the Securities Act or any state securities laws, or facilitate the perfection of any exemption from the registration or qualification requirements of the Securities Act or any applicable state securities laws for the issuance or transfer of any securities. The Company may issue stop/transfer instructions and/or appropriately legend any stock certificates issued pursuant to this Award in order to ensure compliance with the foregoing.

If the sale of Shares acquired under this Award is not registered under the Securities Act, but an exemption is available which requires an investment representation or other representation and warranty, you shall represent and agree that the Shares being acquired are being acquired for investment, and not with a view to the sale or distribution thereof, and shall make such other representations and warranties as are deemed necessary or appropriate by the Company and its counsel.

You may also be required, as a condition of this Award, to enter into any Company stockholder agreement or other agreements that are applicable to stockholders.

You expressly acknowledge and agree to be bound by Section 15(e) of the Plan, which contains provisions addressing the Company’s policy on recoupment of equity or other compensation.

Your Award or this Agreement does not give you the right to be retained by the Company (or any Parent or any Subsidiaries or Affiliates) in any capacity. The Company (or any Parent and any Subsidiaries or Affiliates) reserves the right to terminate your Service at any time and for any reason.

This Award and the Shares subject to the Award are not intended to constitute or replace any pension rights or compensation and are not to be considered compensation of a continuing or recurring nature, or part of your normal or expected compensation, and in no way represent any portion of your salary, compensation or other remuneration for any purpose, including but not limited to, calculating any severance, resignation, termination, redundancy, dismissal, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments.

In the event of a stock split, a stock dividend or a similar change in the Company stock, the number of outstanding Stock Units covered by this Award shall be adjusted (and rounded down to the nearest whole number) pursuant to the Plan. Your Stock Units shall be subject to the terms of the agreement of merger, liquidation or reorganization in the event the Company is subject to such corporate activity.

All certificates or book entries representing the Common Stock issued under this Award may, where applicable, have endorsed thereon the following notations or legends and any other notation or legend the Company determines appropriate:

“THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND OPTIONS TO PURCHASE SUCH SHARES SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER, OR HIS OR HER PREDECESSOR IN INTEREST. A COPY OF SUCH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY AND WILL BE FURNISHED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY BY THE HOLDER OF RECORD OF THE SHARES REPRESENTED BY THIS CERTIFICATE.”

“THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED OR QUALIFIED UNDER THE SECURITIES LAWS OF ANY STATE, AND MAY NOT BE SOLD, PLEDGED, OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR QUALIFICATION UNDER APPLICABLE STATE LAWS OR AN OPINION OF COUNSEL, SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION OR QUALIFICATION IS NOT REQUIRED.”

This Agreement will be interpreted and enforced under the laws of the State of Delaware without reference to the conflicts of law provisions thereof.

The issuance of Common Stock pursuant to this Agreement shall be subject to full compliance with all applicable requirements of law and the requirements of any stock exchange or interdealer quotation system upon which the Common Stock may be listed or traded.

This Agreement shall be binding upon and inure to the benefit of the Company and you and any respective heirs, representatives, successors and permitted assigns. This Agreement shall not confer any rights or remedies upon any person other than the Company and you and any respective heirs, representatives, successors and permitted assigns. The parties agree that this Agreement shall survive the settlement or termination of the Award.

Any notice to be given or delivered to the Company relating to this Agreement shall be in writing and addressed to the Company at its principal corporate offices. All notices shall be deemed effective upon personal delivery or upon deposit in the postal mail, postage prepaid and properly addressed to the Company. Any notice to be given or delivered to you relating to this Agreement may be delivered by electronic form including without limitation by email (including prospectuses required by the SEC) as well as all other documents that the Company is required to deliver to its security holders (including annual reports and proxy statements). The Company may also deliver these documents by posting them on a web site maintained by the Company or by a third party under contract with the Company.

Voluntary

Participant

You acknowledge that you are voluntarily participating in the Plan.

Your rights, if any, in respect of or in connection with this Award or any other Awards are derived solely from the discretionary decision of the Company to permit you to participate in the Plan and to benefit from a discretionary future Award. By accepting this Award, you expressly acknowledge that there is no obligation on the part of the Company to continue the Plan and/or grant any additional Awards to you or benefits in lieu of other Awards even if Awards have been granted repeatedly in the past. All decisions with respect to future Awards, if any, will be at the sole discretion of the Committee.

The future value of the underlying Shares is unknown and cannot be predicted with certainty. If the underlying Shares do not maintain or increase their value after the Date of Award, the Award could have little or no value. If you obtain Shares under this Award, the value of the Shares acquired upon settlement may subsequently increase or decrease in value, and could decrease to a value less than the taxes payable upon settlement.

The Company has not provided any tax, legal or financial advice, nor has the Company made any recommendations regarding your participation in the Plan, or your acquisition or sale of the underlying Shares. You are hereby advised to consult with your own personal tax, legal and financial advisors regarding your participation in the Plan before taking any action related to the Plan.

You will have no right to bring a claim or to receive damages if any portion of the Award is cancelled or expires. The loss of existing or potential profit in the Award will not constitute an element of damages in the event of the termination of your Service for any reason, even if the termination is in violation of an obligation of the Company or a Parent or a Subsidiary or an Affiliate to you.

You hereby explicitly and unambiguously consent to the collection, use and transfer, in electronic or other form, of your personal data as described in this document by the Company for the exclusive purpose of implementing, administering and managing your participation in the Plan.

home address and telephone number, date of birth, gender, social security or insurance number or other identification number, salary, nationality, job title, any shares of stock or directorships held in the Company, details of all Awards or any other entitlement to Shares awarded, cancelled, purchased, exercised, vested, unvested or outstanding in your favor for the purpose of implementing, managing and administering the Plan (“Data”). You understand that the Data may be transferred to any third parties assisting in the implementation, administration and management of the Plan, that these recipients may be located in your country or elsewhere and that the recipient country may have different data privacy laws and protections than your country. You authorize the recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing your participation in the Plan, including any requisite transfer of such Data, as may be required to a broker or other third party with whom you may elect to deposit any Shares acquired under the Plan.

You agree to receive stockholder information, including copies of any annual report, proxy statement and periodic report, from the Company’s website, if the Company wishes to provide such information through its website. You acknowledge that copies of the Plan, Plan prospectus, Plan information and stockholder information are also available upon written or telephonic request to the Plan’s administrator.

You agree to provide assistance reasonably requested by the Company in connection with actions taken by you while providing services to the Company, including but not limited to assistance in connection with any lawsuits or other claims against the Company arising from events during the period in which you rendered service to the Company.

The Company (or any Parent or any Subsidiaries or Affiliates) is not responsible for your legal compliance requirements relating to this Award, including, but not limited to, tax reporting.

Additional

Conditions

If the Company shall determine, in its sole discretion, that the consent or approval of any governmental authority is necessary or desirable as a condition to the payment of benefits to you pursuant to the Plan, such payment shall not occur until such registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Company.

The Company will be entitled to enforce its rights under this Agreement specifically, to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights to which it may be entitled. You agree and acknowledge that money damages may not be an adequate remedy for breach of the provisions of this Agreement and that the Company may in its sole discretion apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive relief in order to enforce or prevent any violations of the provisions of this Agreement.

You acknowledge that the businesses of the Company is highly competitive and that the Company’s strategies, methods, books, records, and documents, technical information concerning their products, equipment, services, and processes, procurement procedures and pricing techniques, the names of and other information (such as credit and financial data) concerning former, present or prospective customers and business affiliates, all comprise confidential business information and trade secrets which are valuable, special, and unique assets which the Company uses in their business to obtain a competitive advantage over competitors. You further acknowledge that protection of such confidential business information and trade secrets against unauthorized disclosure and use is of critical importance to the Company in maintaining its competitive position. You acknowledge that by reason of your duties to and association with the Company, you have had and will have access to and have and will become informed of confidential business information which is a competitive asset of the Company. You hereby agree that you will not, at any time during or after employment, make any unauthorized disclosure of any confidential business information or trade secrets of the Company, or make any use thereof, except in the carrying out of services responsibilities. You shall take all necessary and appropriate steps to safeguard confidential business information and protect it against disclosure, misappropriation, misuse, loss and theft. Confidential business information shall not include information in the public domain (but only if the same becomes part of the public domain through a means other than a disclosure prohibited hereunder). The above notwithstanding, a disclosure shall not be unauthorized if (i) it is required by law or by a court of competent jurisdiction or (ii) it is in connection with any judicial, arbitration, dispute resolution or other legal proceeding in which your legal rights

and obligations as a service provider or under this Agreement are at issue; provided, however, that you shall, to the extent practicable and lawful in any such events, give prior notice to the Company of your intent to disclose any such confidential business information in such context so as to allow the Company an opportunity (which you will not oppose) to obtain such protective orders or similar relief with respect thereto as may be deemed appropriate. Any information not specifically related to the Company would not be considered confidential to the Company. In the event of any conflict in terms between this Section 30 and the terms of any Company confidentiality or proprietary information agreement you have executed, the terms of such other confidentiality or proprietary information agreement shall prevail and govern.
