Ladies and Gentlemen:

          Diodes Incorporated, a Delaware corporation (the “Company”), proposes to issue and sell to the underwriters named in Schedule A annexed hereto (the “Underwriters”) for whom you are acting as representative, $200,000,000 aggregate principal amount of the Company’s 2.25% Convertible Senior Notes due 2026 (such principal amount, the “Firm Notes”) to be issued pursuant to the provisions of an indenture to be dated as of October 12, 2006 (the “Indenture” and collectively with this Agreement and the Notes, the “Transaction Documents”) between the Company and Union Bank of California, N.A., as trustee. In addition, solely for the purpose of covering over-allotments, the Company proposes to grant to the Underwriters the option to purchase from the Company up to an additional $30,0000,000 of aggregate principal amount of Notes (the “Additional Notes”). The Firm Notes and the Additional Notes are hereinafter collectively sometimes referred to as the “Notes.” The Notes are described in the Prospectus which is referred to below.

          The Notes will be convertible into shares of common stock of the Company, $0.66⅔ par value per share (“Common Stock”). The shares of Common Stock into which the Notes may be converted are referred to herein as the “Underlying Securities.”

          The Company has prepared and filed, in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively, the “Act”), with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-137803) under the Act (the “registration statement”) including a prospectus, which registration statement incorporates by reference documents which the Company has filed, or will file, in accordance with the provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the “Exchange Act”). Such registration statement has become effective under the Act.

          Except where the context otherwise requires, “Registration Statement,” as used herein, means the registration statement, as amended at the time of such registration statement’s effectiveness for purposes of Section 11 of the Act, as such section applies to the respective Underwriters (the “Effective Time”), including (i) all documents filed as a part thereof or incorporated or deemed to be incorporated by reference therein, (ii) any information contained or

incorporated by reference in a prospectus filed with the Commission pursuant to Rule 424(b) under the Act, to the extent such information is deemed, pursuant to Rule 430A, Rule 430B or Rule 430C under the Act, to be part of the registration statement at the Effective Time, and (iii) any registration statement filed to register the offer and sale of Notes pursuant to Rule 462(b) under the Act. The Company has furnished to you, for use by the Underwriters and by dealers in connection with the offering of the Notes, copies of one or more preliminary prospectuses, and the documents incorporated by reference therein, relating to the Notes. Except where the context otherwise requires, “Pre-Pricing Prospectus,” as used herein, means each such preliminary prospectus, in the form so furnished.

          Except where the context otherwise requires, “Prospectus,” as used herein, means the final prospectus, relating to the Notes, filed by the Company with the Commission pursuant to Rule 424(b) under the Act on or before the second business day after the date hereof (or such earlier time as may be required under the Act), in the form furnished by the Company to you for use by the Underwriters and by dealers in connection with the offering of the Notes.

          “Permitted Free Writing Prospectuses,” as used herein, means the documents listed on Schedule B attached hereto and each “road show” (as defined in Rule 433 under the Act), if any, related to the offering of the Notes contemplated hereby that is a “written communication” (as defined in Rule 405 under the Act). The Underwriters have not offered or sold and will not offer or sell, without the Company’s consent, any Notes by means of any “free writing prospectus” (as defined in Rule 405 under the Act) that is required to be filed by the Underwriters with the Commission pursuant to Rule 433 under the Act, other than a Permitted Free Writing Prospectus.

          “Disclosure Package,” as used herein, means any Pre-Pricing Prospectus together with any combination of one or more of the Permitted Free Writing Prospectuses, if any.

          Any reference herein to the registration statement, the Registration Statement, any Pre-Pricing Prospectus, the Prospectus or any Permitted Free Writing Prospectus shall be deemed to refer to and include the documents, if any, incorporated by reference, or deemed to be incorporated by reference, therein (the “Incorporated Documents”), including, unless the context otherwise requires, the documents, if any, filed as exhibits to such Incorporated Documents. Any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, any Pre-Pricing Prospectus, the Prospectus or any Permitted Free Writing Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act on or after the initial effective date of the Registration Statement, or the date of such Pre-Pricing Prospectus, the Prospectus or such Permitted Free Writing Prospectus, as the case may be, and deemed to be incorporated therein by reference.

          As used in this Agreement, “business day” shall mean a day on which the NASDAQ National Market (the “NASDAQ”) is open for trading. The terms “herein,” “hereof,” “hereto,” “hereinafter” and similar terms, as used in this Agreement, shall in each case refer to this Agreement as a whole and not to any particular section, paragraph, sentence or other subdivision of this Agreement. The term “or,” as used herein, is not exclusive.

          The Company and the Underwriters agree as follows:

          1. Sale and Purchase. Upon the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Company agrees to issue and sell to the respective Underwriters and each of the Underwriters, severally and not jointly, agrees to purchase from the Company principal amount of Firm Notes set forth opposite the name of such Underwriter in Schedule A attached hereto, subject to adjustment in accordance with Section 8 hereof, in each case at a purchase price of 97.375% of the principal amount thereof, plus accrued interest (if any) to the time of purchase (as defined below). The Company is advised by you that the Underwriters intend (i) to make a public offering of their respective portions of the Firm Notes as soon after the effectiveness of this Agreement as in your judgment is advisable and (ii) initially to offer the Firm Notes upon the terms set forth in the Prospectus. You may from time to time increase or decrease the public offering price after the initial public offering to such extent as you may determine.

          In addition, the Company hereby grants to the several Underwriters the option (the “Over-Allotment Option”) to purchase, and upon the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Underwriters shall have the right to purchase, severally and not jointly, from the Company, ratably in accordance with the aggregate principal amount of Firm Notes to be purchased by each of them, all or a portion of the Additional Notes as may be necessary to cover over-allotments made in connection with the offering of the Firm Notes, at the same purchase price (expressed as a percentage of the principal amount) to be paid by the Underwriters to the Company for the Firm Notes. The Over-Allotment Option may be exercised by UBS Securities LLC (“UBS”) on behalf of the several Underwriters at any time and from time to time (provided that the Additional Notes shall be issued on or before the thirteenth (13th) day beginning with, and including, the date of original issuance of the Firm Notes) by written notice to the Company. Such notice shall set forth the aggregate principal amount of Additional Notes as to which the Over-Allotment Option is being exercised, and the date and time when the Additional Notes are to be delivered (any such date and time being herein referred to as an “additional time of purchase”); provided, however, that no additional time of purchase shall be earlier than the time of purchase (as defined below) nor earlier than the second business day after the date on which the Over-Allotment Option shall have been exercised nor later than the tenth business day after the date on which the Over-Allotment Option shall have been exercised and the Additional Notes shall have been issued within the aforementioned period. The principal amount of Additional Notes to be sold to each Underwriter shall be the principal amount which bears the same proportion to the aggregate principal amount of Additional Notes being purchased as the principal amount of Firm Notes set forth opposite the name of such Underwriter on Schedule A hereto bears to the aggregate principal amount of Firm Notes, subject to adjustment in accordance with Section 8 hereof.

          2. Payment and Delivery. Payment of the purchase price for the Firm Notes shall be made to the Company by Federal Funds wire transfer, against delivery of the certificates for the Firm Notes to you through the facilities of The Depository Trust Company (“DTC”) for the respective accounts of the Underwriters. Such payment and delivery shall be made at 10:00 A.M., New York City time, on October 12, 2006 (the “Closing Date”) (unless another time shall be agreed to by you and the Company or unless postponed in accordance with the provisions of Section 8 hereof). The time at which such payment and delivery are to be made is hereinafter sometimes called the “time of purchase.” Electronic transfer of the Firm Notes shall be made to you at the time of purchase in such names and in such denominations as you shall specify.

          Payment of the purchase price for the Additional Notes shall be made at the additional time of purchase in the same manner and at the same office as the payment for the Firm Notes. Electronic transfer of the Additional Notes shall be made to you at the additional time of purchase in such names and in such denominations as you shall specify.

          Certificates for the Notes shall be in definitive form or global form, as specified by you, and registered in the names and in such denominations as you shall request in writing not later than one full business day prior to the time of purchase or the additional time of purchase, as the case may be. For the purpose of expediting the checking of the certificates for the Notes by you, the Company agrees to make such certificates available to you for such purpose at least one full business day preceding the time of purchase or the additional time of purchase, as the case may be.

          Deliveries of the documents described in Section 6 hereof with respect to the purchase of the Notes shall be made at the offices of Simpson Thacher & Bartlett LLP, Underwriters’ counsel at the address of its Palo Alto office, at or prior to 9:00 A.M., New York City time, on the date of the closing of the purchase of the Firm Notes or the Additional Notes, as the case may be.

          The obligations of the several Underwriters hereunder shall be subject to termination in the absolute discretion of UBS, if (x) since the time of execution of this Agreement or the earlier respective dates as of which information is given in the Registration Statement, the Pre-Pricing Prospectuses, the Prospectus and the Permitted Free Writing Prospectuses, if any, there has been any material adverse change or any development involving a prospective material adverse change in the business, properties, management, financial condition or results of operations of the Company and the Subsidiaries taken as a whole, which would, in UBS’ sole judgment, make it impracticable or inadvisable to proceed with the public offering or the delivery of the Notes on the terms and in the manner contemplated in the Registration Statement, the Pre-Pricing Prospectuses, the Prospectus and the Permitted Free Writing Prospectuses, if any, or (y) since the date of execution of this Agreement, there shall have occurred: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange, the American Stock Exchange or the NASDAQ; (ii) a suspension or material limitation in trading in the Company’s securities on the NASDAQ; (iii) a general moratorium on commercial banking activities declared by either federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) an outbreak or escalation of hostilities or acts of terrorism involving the United States or a declaration by the United States of a national emergency or war; or (v) any other calamity or crisis or any change in financial, political or economic conditions in

27

the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in UBS’ sole judgment makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Notes on the terms and in the manner contemplated in the Registration Statement, the Pre-Pricing Prospectuses, the Prospectus and the Permitted Free Writing Prospectuses, if any, or (z) since the date of execution of this Agreement, there shall have occurred any downgrading, or any notice or announcement shall have been given or made of (i) any intended or potential downgrading or (ii) any watch, review or possible change that does not indicate an affirmation or improvement, in the rating accorded any securities of or guaranteed by the Company or any Subsidiary by any “nationally recognized statistical rating organization,” as that term is defined in Rule 436(g)(2) under the Act.

          If UBS elects to terminate this Agreement as provided in this Section 7, the Company and each other Underwriter shall be notified promptly in writing.

          If the sale to the Underwriters of the Notes, as contemplated by this Agreement, is not carried out by the Underwriters for any reason permitted under this Agreement or if such sale is not carried out because the Company shall be unable to comply with any of the terms of this Agreement, the Company shall not be under any obligation or liability under this Agreement (except to the extent provided in Sections 4(p), 5 and 9 hereof), and the Underwriters shall be under no obligation or liability to the Company under this Agreement (except to the extent provided in Section 9 hereof) or to one another hereunder.

          8. Increase in Underwriters’ Commitments. Subject to Sections 6 and 7 hereof, if any Underwriter shall default in its obligation to take up and pay for the Firm Notes to be purchased by it hereunder (otherwise than for a failure of a condition set forth in Section 6 hereof or a reason sufficient to justify the termination of this Agreement under the provisions of Section 7 hereof) and if the aggregate principal amount of Firm Notes which all Underwriters so defaulting shall have agreed but failed to take up and pay for does not exceed 10% of the aggregate principal amount of Firm Notes, the non-defaulting Underwriters (including the Underwriters, if any, substituted in the manner set forth below) shall take up and pay for (in addition to the aggregate principal amount of Firm Notes they are obligated to purchase pursuant to Section 1 hereof) the aggregate principal amount of Firm Notes agreed to be purchased by all such defaulting Underwriters, as hereinafter provided. Such Notes shall be taken up and paid for by such non-defaulting Underwriters in such amount or amounts as you may designate with the consent of each Underwriter so designated or, in the event no such designation is made, such Notes shall be taken up and paid for by all non-defaulting Underwriters pro rata in proportion to the aggregate principal amount of Firm Notes set forth opposite the names of such non-defaulting Underwriters in Schedule A.

          Without relieving any defaulting Underwriter from its obligations hereunder, the Company agrees with the non-defaulting Underwriters that it will not sell any Firm Notes hereunder unless all of the Firm Notes are purchased by the Underwriters (or by substituted Underwriters selected by you with the approval of the Company or selected by the Company with your approval).

          If a new Underwriter or Underwriters are substituted by the Underwriters or by the Company for a defaulting Underwriter or Underwriters in accordance with the foregoing

28

provision, the Company or you shall have the right to postpone the time of purchase for a period not exceeding five business days in order that any necessary changes in the Registration Statement, the Pre-Pricing Prospectus, the Prospectus, the Permitted Free Writing Prospectus, if any, and other documents may be effected.

          The term Underwriter as used in this Agreement shall refer to and include any Underwriter substituted under this Section 8 with like effect as if such substituted Underwriter had originally been named in Schedule A.

          If the aggregate principal amount of Firm Notes which the defaulting Underwriter or Underwriters agreed to purchase exceeds 10% of the aggregate principal amount of Firm Notes which all Underwriters agreed to purchase hereunder, and if neither the non-defaulting Underwriters nor the Company shall make arrangements within the five business day period stated above for the purchase of all the Firm Notes which the defaulting Underwriter or Underwriters agreed to purchase hereunder, this Agreement shall terminate without further act or deed and without any liability on the part of the Company to any non-defaulting Underwriter and without any liability on the part of any non-defaulting Underwriter to the Company. Nothing in this paragraph, and no action taken hereunder, shall relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

          9. Indemnity and Contribution.

          (a) The Company agrees to indemnify, defend and hold harmless each Underwriter, its partners, directors and officers, and any person who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, any such Underwriter or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or arises out of or is based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information concerning such Underwriter furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in the Registration Statement or arises out of or is based upon any omission or alleged omission to state a material fact in the Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading, (ii) any untrue statement or alleged untrue statement made by the Company in Section 3 hereof or the failure by the Company to perform when and as required any agreement or covenant contained herein, or (iii) any untrue statement or alleged untrue statement of a material fact included in any Prospectus (the term Prospectus for the purpose of this Section 9 being deemed to include any Pre-

Pricing Prospectus, the Prospectus and any amendments or supplements to the foregoing), in any Permitted Free Writing Prospectus, in any “issuer information” (as defined in Rule 433 under the Act) of the Company or in any Prospectus together with any combination of one or more of the Permitted Free Writing Prospectuses, if any, or arises out of or is based upon any omission or alleged omission to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except, with respect to such Prospectus or Permitted Free Writing Prospectus, insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Underwriter furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in, such Prospectus or Permitted Free Writing Prospectus or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

     If any action, suit or proceeding (each, a “Proceeding”) is brought against an Underwriter or any such person in respect of which indemnity may be sought against the Company pursuant to the foregoing paragraph, such Underwriter or such person shall promptly notify the Company in writing of the institution of such Proceeding and the Company shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify the Company shall not relieve the Company from any liability which the Company may have to any Underwriter or any such person or otherwise, except where such omission results in material prejudice to the Company that affects the rights of the Company. Such Underwriter or such person shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such Underwriter or of such person unless the employment of such counsel shall have been authorized in writing by the Company in connection with the defense of such Proceeding or the Company shall not have, within a reasonable period of time in light of the circumstances, employed counsel to have charge of the defense of such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from, additional to or in conflict with those available to the Company (in which case the Company shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the Company and paid as incurred (it being understood, however, that the Company shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). The Company shall not be liable for any settlement of any Proceeding effected without its written consent but if settled with the written consent of the Company, the Company agrees to indemnify and hold harmless any Underwriter and any such person from and against any loss or liability by reason of such settlement to the extent otherwise required by this Section 9(a). Notwithstanding the foregoing sentence,

if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this paragraph, then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party.

          (b) Each Underwriter severally agrees to indemnify, defend and hold harmless the Company, its directors and officers and any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Company, or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information concerning such Underwriter furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company), or arises out of or is based upon any omission or alleged omission to state a material fact in such Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Underwriter furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in, a Prospectus or a Permitted Free Writing Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

     If any Proceeding is brought against the Company or any such person in respect of which indemnity may be sought against any Underwriter pursuant to the foregoing paragraph, the Company or such person shall promptly notify such Underwriter in writing of the institution of such Proceeding and such Underwriter shall assume the

defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify such Underwriter shall not relieve such Underwriter from any liability which such Underwriter may have to the Company or any such person or otherwise, except to such extent as such Underwriter is materially prejudiced by such omission. The Company or such person shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the Company or such person unless the employment of such counsel shall have been authorized in writing by such Underwriter in connection with the defense of such Proceeding or such Underwriter shall not have, within a reasonable period of time in light of the circumstances, employed counsel to defend such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to or in conflict with those available to such Underwriter (in which case such Underwriter shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties, but such Underwriter may employ counsel and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of such Underwriter), in any of which events such fees and expenses shall be borne by such Underwriter and paid as incurred (it being understood, however, that such Underwriter shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). No Underwriter shall be liable for any settlement of any such Proceeding effected without the written consent of such Underwriter but if settled with the written consent of such Underwriter, such Underwriter agrees to indemnify and hold harmless the Company and any such person from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this paragraph, then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party.

          (c) If the indemnification provided for in this Section 9 is unavailable to an indemnified party under subsections (a) and (b) of this Section 9 or insufficient to hold an indemnified party harmless in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable indemnifying party shall

contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Notes or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, bear to the aggregate public offering price of the Notes. The relative fault of the Company on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding.

          (d) The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in subsection (c) above. Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by such Underwriter and distributed to the public were offered to the public exceeds the amount of any damage which such Underwriter has otherwise been required to pay by reason of such untrue statement or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 9 are several in proportion to their respective underwriting commitments and not joint.

          (e) The indemnity and contribution agreements contained in this Section 9 and the covenants, warranties and representations of the Company contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of any Underwriter, its partners, directors or officers or any person (including each partner, officer or director of such person) who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or on behalf of the Company, its directors or officers or any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act,

and shall survive any termination of this Agreement or the issuance and delivery of the Notes. The Company and each Underwriter agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Company, against any of the Company’s officers or directors, in connection with the issuance and sale of the Notes, or in connection with the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus.

          10. Information Furnished by the Underwriters. The public offering price set forth in the table on the cover page of the Prospectus and the statements set forth in the second and third sentences of the first paragraph under the caption “Underwriting—Commissions and discounts” and the first five paragraphs under the caption “Underwriting—Price stabilization, short positions, passive market making” in the Prospectus constitute the only information furnished by or on behalf of the Underwriters as such information is referred to in Sections 3 and 9 hereof.

          11. Notices. Except as otherwise herein provided, all statements, requests, notices and agreements shall be in writing or by telegram or facsimile and, if to the Underwriters, shall be sufficient in all respects if delivered or sent to UBS Securities LLC, 299 Park Avenue, New York, NY 10171-0026, Attention: Syndicate Department, with a copy to Simpson Thacher & Bartlett LLP, 2550 Hanover Street, Palo Alto CA 94304, Attention William B. Brentani; and if to the Company, shall be sufficient in all respects if delivered or sent to the Company at the offices of the Company at 3050 E. Hillcrest Drive, Westlake Village, CA 91362, Attention: Carl C. Wertz, with a copy sent to Sheppard, Mullin, Richter & Hampton LLP 333 South Hope Street, 48^th Floor, Los Angeles, CA 90071, Attention Peter M. Menard, Esq.

          12. Governing Law; Construction. This Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement (“Claim”), directly or indirectly, shall be governed by, and construed in accordance with, the laws of the State of New York. The Section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement.

          13. Submission to Jurisdiction. Except as set forth below, no Claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and each of the Company consents to the jurisdiction of such courts and personal service with respect thereto. The Company hereby consents to personal jurisdiction, service and venue in any such court and in any court in which any Claim arising out of or in any way relating to this Agreement is brought by any third party against any Underwriter or any indemnified party. Each of UBS and the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Company agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Company and may be enforced in any other courts to the jurisdiction of which the Company is or may be subject, by suit upon such judgment.

          14. Parties at Interest. The Agreement herein set forth has been and is made solely for the benefit of the Underwriters and the Company and to the extent provided in Section 9 hereof the controlling persons, directors and officers referred to in such section, and their respective successors, assigns, heirs, personal representatives and executors and administrators. No other person, partnership, association or corporation (including a purchaser, as such purchaser, from any of the Underwriters) shall acquire or have any right under or by virtue of this Agreement.

          15. No Fiduciary Relationship. The Company hereby acknowledges that the Underwriters are acting solely as underwriters in connection with the purchase and sale of the Company’s securities. The Company further acknowledges that the Underwriters are acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis and in no event do the parties intend that the Underwriters act or be responsible as a fiduciary to the Company, its management, stockholders, creditors or any other person in connection with any activity that the Underwriters may undertake or have undertaken in furtherance of the purchase and sale of the Company’s securities, either before or after the date hereof. The Underwriters hereby expressly disclaim any fiduciary or similar obligations to the Company, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company hereby confirms its understanding and agreement to that effect. The Company and the Underwriters agree that they are each responsible for making their own independent judgments with respect to any such transactions, and that any opinions or views expressed by the Underwriters to the Company regarding such transactions, including but not limited to any opinions or views with respect to the price or market for the Company’s securities, do not constitute advice or recommendations to the Company. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company and may have against the Underwriters with respect to any breach or alleged breach of any fiduciary or similar duty to the Company in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

          16. Counterparts. This Agreement may be signed by the parties in one or more counterparts which together shall constitute one and the same agreement among the parties.

          17. Successors and Assigns. This Agreement shall be binding upon the Underwriters and the Company and their successors and assigns and any successor or assign of any substantial portion of the Company’s and any of the Underwriters’ respective businesses and/or assets.

          18. Miscellaneous. UBS, an indirect, wholly owned subsidiary of UBS AG, is not a bank and is separate from any affiliated bank, including any U.S. branch or agency of UBS AG. Because UBS is a separately incorporated entity, it is solely responsible for its own contractual obligations and commitments, including obligations with respect to sales and purchases of securities. Securities sold, offered or recommended by UBS are not deposits, are not insured by the Federal Deposit Insurance Corporation, are not guaranteed by a branch or agency, and are not otherwise an obligation or responsibility of a branch or agency.

          A lending affiliate of UBS may have lending relationships with issuers of securities underwritten or privately placed by UBS. To the extent required under the securities

laws, prospectuses and other disclosure documents for securities underwritten or privately placed by UBS will disclose the existence of any such lending relationships and whether the proceeds of the issue will be used to repay debts owed to affiliates of UBS.

Diodes Incorporated

                                        , 2006

UBS Securities LLC
Together with the other
Underwriters named in
Schedule A to the
Underwriting Agreement

c/o UBS Securities LLC
    299 Park Avenue
    New York, New York 10171

Ladies and Gentlemen:

          This Lock-Up Agreement is being delivered to you in connection with the proposed Underwriting Agreement (the “Underwriting Agreement”) to be entered into by Diodes Incorporated, a Delaware corporation (the “Company”), and you and the other underwriters named in Schedule A to the Underwriting Agreement, with respect to the public offering (the “Offering”) of Convertible Senior Notes due 2026 of the Company (the “Notes”), which Notes are convertible into shares of common stock, par value $0.66⅔ per share, of the Company (the “Common Stock”).

          In order to induce you to enter into the Underwriting Agreement, the undersigned agrees that for a period beginning on the date hereof and ending on, and including, the date that is 90 days after the date of the final prospectus relating to the Offering (the “Lock-Up Period”) the undersigned will not, without the prior written consent of UBS Securities LLC (“UBS”), (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or file (or participate in the filing of) a registration statement with the Securities and Exchange Commission (the “Commission”) in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder (the “Exchange Act”) with respect to, any Notes, any Common Stock, any debt securities substantially similar to the Notes (“debt securities”), or any other securities of the Company that are substantially similar to Common Stock, or any securities convertible into or exchangeable or exercisable for, or any warrants or other rights to purchase, the foregoing, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Notes, Common Stock, debt securities or any other securities of the Company that are substantially similar to Common Stock, or any securities convertible into or exchangeable or exercisable for, or any warrants or other rights to purchase,

the foregoing, whether any such transaction is to be settled by delivery of Notes, Common Stock or such other securities, in cash or otherwise, or (iii) publicly announce an intention to effect any transaction specified in clause (i) or (ii). The foregoing sentence shall not apply to (a) the registration of the offer and sale of Notes as contemplated by the Underwriting Agreement and the sale to the Underwriters of any Notes pursuant to the Offering, (b) bona fide gifts, provided the recipient thereof agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Agreement and confirm that he, she or it has been in compliance with terms of this Lock-Up Agreement since the date hereof [,][or] (c) dispositions to any trust for the direct or indirect benefit of the undersigned and/or the immediate family of the undersigned, provided that such trust agrees in writing with the Underwriters to be bound by the terms of this Lock-Up Letter Agreement and confirms that it has been in compliance with the terms of this Lock-Up Letter Agreement since the date hereof [,or (d) any sale or offer pursuant to a plan existing on the date hereof that meets the requirements of Rule 10b5-1(c) promulgated pursuant to the Exchange Act.]¹

          In addition, the undersigned hereby waives any rights the undersigned may have to require registration of Common Stock in connection with the filing of a registration statement relating to the Offering. The undersigned further agrees that, for the duration of the Lock-Up Period, the undersigned will not, without the prior written consent of UBS, make any demand for, or exercise any right with respect to, the registration of Common Stock of the Company or any securities convertible into or exercisable or exchangeable for Common Stock, or warrants or other rights to purchase Common Stock or any such securities.

Notwithstanding the above, if:

	(1)		during the period that begins on the date that is 15 calendar days plus 3 business days before the last day of the Lock-Up Period and ends on the last day of the Lock-Up Period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or
	(2)		prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period,

the restrictions imposed by this Lock-Up Agreement shall continue to apply until the expiration of the date that is 15 calendar days plus 3 business days after the date on which the issuance of the earnings release or the material news or material event occurs; provided, however, that this paragraph will not apply if, (a) the safe harbor provided by Rule 139 under the Act is available in the manner contemplated by Rule 2711(f)(4) of the NASD and (b) within the 3 business days preceding the 15th calendar day before the last day of the Lock-Up Period, the Company delivers (in accordance with Section 11) to UBS a certificate, signed by the Chief Financial Officer or Chief Executive Officer of the Company, certifying on behalf of the Company that the

Company’s shares of Common Stock are “actively traded securities,” within the meaning of Rule 2711(f)(4) of the NASD.

          The undersigned hereby confirms that the undersigned has not, directly or indirectly, taken, and hereby covenants that the undersigned will not, directly or indirectly, take, any action designed, or which has constituted or will constitute or might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of Notes or shares of Common Stock.

          If (i) the Company notifies you in writing that it does not intend to proceed with the Offering, (ii) the registration statement filed with the Securities and Exchange Commission with respect to the Offering is withdrawn or (iii) for any reason the Underwriting Agreement shall be terminated prior to the time of purchase (as defined in the Underwriting Agreement), this Lock-Up Agreement shall be terminated and the undersigned shall be released from its obligations hereunder.

OPINION OF SHEPPARD, MULLIN, RICHTER & HAMPTON LLP
AS COUNSEL TO THE COMPANY AND THE SELLING STOCKHOLDER

          We have acted as special counsel to Diodes Incorporated, a Delaware corporation (the “Company”), in connection with the offering for sale to the underwriters named in Schedule A to the Underwriting Agreement referred to below (the “Underwriters”) of (i) $200,000,000 aggregate principal amount of 2.25% Convertible Senior Notes due 2026 of the Company (the “Firm Notes”) pursuant to that certain Underwriting Agreement, dated October 5, 2006, by and among the Company and the Underwriters (the “Underwriting Agreement”) and (ii) up to $30,000,000 aggregate principal amount of 2.25% Convertible Senior Notes due 2026 of the Company (the “Additional Notes”), pursuant to the Underwriting Agreement, at the Underwriters’ option solely to cover over-allotments. The Firm Notes and the Additional Notes are collectively referred to herein as the “Notes.” Any reference to the “Company” herein refers, to Diodes Incorporated only, and does not include any of its subsidiaries. This opinion is given to you pursuant to Section 6(a) of the Underwriting Agreement. Unless defined herein, capitalized terms have the meanings given them in the Underwriting Agreement.

          As to matters of fact, we are relying upon the representations and warranties of all parties contained in the Transaction Documents, the certificates of certain officers of the Company (the “Opinion Certificates”) and certificates and other communications of government officials, all without independent verification. In addition, we examined originals or copies of documents, corporate records and other writings that we consider relevant for the purposes of this opinion. In such examination, we assumed that the signatures on documents and instruments examined by us are authentic, that each is complete and what it purports to be, that all documents and instruments submitted to us as copies or facsimiles conform with the originals, and that the documents and instruments submitted to us have not been amended or modified since the date submitted.

          In our examination of documents, we further assumed (i) that each person or entity entering into such documents (other than the Company in connection with the Transaction Documents) had the power, legal competence and capacity to enter into and perform all of such party’s obligations thereunder, (ii) the due execution and delivery of such documents by each party thereto (other than the due execution and delivery of the Transaction Documents by the Company), (iii) the enforceability and binding nature of the obligations of the parties to such documents, (iv) performance on or before the time of purchase and the additional time of purchase, if any, by all parties of their obligations under the Transaction Documents to be performed on or before the time of purchase or the additional time of purchase, if any, and (v) that no action has been taken or has occurred which amends, revokes, terminates or renders invalid any of the documents, records, consents or resolutions which we have reviewed. We also assumed that there are no extrinsic agreements or understandings among the parties to the Transaction Documents or Contracts (as defined below) that would modify or interpret the terms of the Transaction Documents or Contracts or the respective rights or obligations of the parties thereunder.

          As used in this opinion, the expression “to our knowledge” or “known to us” with reference to matters of fact refers to the current actual conscious awareness of the attorneys within the firm who have rendered legal services in connection with the transactions covered by this opinion, or who have been involved in substantive legal representation of the Company since January 1, 2004. Except to the extent expressly set forth herein we have not undertaken any independent investigation to determine the accuracy or completeness of any such statement of fact, and no inference as to the accuracy or completeness of any such statement should be drawn from our representation of the Company or our rendering of the opinions set forth below.

          Based upon and subject to the foregoing and the qualifications and limitations set forth below, and except as set forth in the Pre-Pricing Prospectus, the Prospectus and the Registration Statement, it is our opinion that:

     (i) the Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware, with corporate power and authority to own, lease and operate its properties and conduct its business as described in the Registration Statement, the Pre-Pricing Prospectus, the Prospectus and the Permitted Free Writing Prospectus identified on Annex A hereto (the “Permitted Free Writing Prospectus”), to execute and deliver the Underwriting Agreement and to issue, sell and deliver the Notes and to issue and deliver the Underlying Securities initially issuable upon conversion of the Notes in accordance with the Indenture and the Notes;

     (ii) the Company is duly qualified to do business as a foreign corporation and is in good standing in each United States jurisdiction where the ownership or leasing of its properties or the conduct of its business requires such qualification, except where the failure to be so qualified and in good standing would not, individually or in the aggregate, have a Material Adverse Effect;

     (iii) the Underwriting Agreement has been duly authorized, executed and delivered by the Company;

     (iv) the Indenture has been duly authorized, executed and delivered by the Company and, assuming due execution by the Trustee, constitutes the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except to the extent that enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfer), reorganization, moratorium or other similar laws affecting creditors’ rights generally and by general principles of equity (regardless of whether enforcement is sought in equity or at law). The Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended (the “TIA”). The form and terms of the Notes have been established in conformity with the provisions of the Indenture;

     (v) the Notes have been duly authorized, executed and delivered by the Company and, when executed and authenticated in accordance with the Indenture and delivered to and paid for by the Underwriters pursuant to the

Underwriting Agreement, will constitute valid and binding obligations of the Company, entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms, except to the extent that enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfer, preferential transfers and distributions and equitable subordination), reorganization, moratorium and other similar laws affecting the relief of debtors’ or creditors’ rights and remedies generally and by general principles of equity (regardless of whether enforcement is sought in equity or at law);

     (vi) the Underlying Securities have been duly authorized and reserved for issuance upon conversion of the Notes and, when issued upon conversion of the Notes in accordance with the terms of the Indenture, will be validly issued, fully paid and non-assessable and free of statutory preemptive rights and, to our knowledge, contractual preemptive rights, resale rights, rights of first refusal and similar rights;

     (vii) the Company has an authorized and, to our knowledge, outstanding capitalization as set forth in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus (and any similar sections or information, if any, contained in the Permitted Free Writing Prospectus); to our knowledge, all of the issued and outstanding shares of capital stock of the Company have been duly authorized and are validly issued, fully paid and non-assessable; all of the issued and outstanding shares of capital stock of the Company are free of statutory preemptive rights and, to our knowledge, contractual preemptive rights, resale rights, rights of first refusal and similar rights; the Notes are free of statutory preemptive rights and, to our knowledge, contractual preemptive rights, resale rights, rights of first refusal and similar rights;

     (viii) to our knowledge, the Company is the holder of record of all the outstanding shares of capital stock of FabTech and, except as set forth in the Registration Statement (excluding the exhibits thereto), the Pre-Pricing Prospectus and the Prospectus, such shares are not subject to any security interest, other encumbrance or adverse claim;

     (ix) the capital stock of the Company conforms in all material respects to the description thereof contained in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus under the heading “Description of capital stock” and any similar sections or information, if any, contained in the Permitted Free Writing Prospectus; the Notes and the Indenture conform in all material respects to the respective descriptions thereof, if any, contained in the Registration Statement, the Pre-Pricing Prospectus, the Prospectus and the Permitted Free Writing Prospectus;

     (x) to our knowledge, there are no contracts or documents of a character required to be described in the Registration Statement, the Pre-Pricing Prospectus, the Prospectus or the Permitted Free Writing Prospectus or to be filed

as exhibits to the Registration Statement or the Exchange Act Documents (as defined below), that are not so described or filed.

     (xi) the Registration Statement, the Pre-Pricing Prospectus and the Prospectus (except as to the financial statements and schedules and other financial data or statistical data derived therefrom contained therein, as to which we express no opinion) comply as to form in all material respects with the requirements of the Act (including, in the case of the Prospectus, Section 10(a) of the Act); the conditions to the use of Form S-3 in connection with the offering and sale of the Notes as contemplated by the Underwriting Agreement have been satisfied; the Registration Statement meets, and the offering and sale of the Notes as contemplated by the Underwriting Agreement complies with, the requirements of Rule 415 under the Act (including, without limitation, Rule 415(a)(5) under the Act); and each Incorporated Document, at the time such document was filed with the Commission, complied as to form in all material respects with the requirements of the Exchange Act (except as to the financial statements and schedules and other financial data or statistical data derived therefrom contained therein, as to which we express no opinion);

     (xii) to our knowledge, (a) the Company is not an “ineligible issuer” (as defined in Rule 405 under the Act) as of the eligibility determination date for purposes of Rules 164 and 433 under the Act with respect to the offering of the Notes contemplated by the Registration Statement and (b) the Registration Statement constitutes an “automatic shelf registration statement” (as defined in Rule 405 under the Act).

     (xiii) the Registration Statement has become effective under the Act and, to our knowledge, no stop order proceedings with respect thereto are pending or threatened under the Act and, to our knowledge, any required filing of the Prospectus and any supplement thereto pursuant to Rule 424 or Rule 430B under the Act has been made in the manner and within the time period required by such Rule 424 and in compliance with Rule 430A and Rule 430B under the Act;

     (xiv) no approval, authorization, consent or order of or filing with any U.S. federal or state governmental or regulatory commission, board, body, authority or agency is required in connection with the issuance and sale of the Notes or the consummation by the Company of the transactions contemplated by the Transaction Documents other than registration of the offer and sale of the Notes and the Underlying Securities under the Act, which has been effected, or the qualification of the Indenture under the TIA, which has been effected (except we express no opinion as to any necessary qualification under the state securities or blue sky laws of the various jurisdictions in which the Notes are being offered by the Underwriters, or under the rules and regulations of the NASD);

     (xv) the execution, delivery and performance of the Transaction Documents by the Company, the issuance and sale of the Notes and the consummation of the transactions contemplated by the Transaction Documents do

not and will not conflict with, result in any breach or violation of or constitute a default under (nor constitute any event which with notice, lapse of time or both would result in any breach of or constitute a default under) (a) the certificate of incorporation or by-laws of the Company, or (b) any indenture, mortgage, deed of trust, bank loan or credit agreement or other evidence of indebtedness, or any license, lease, contract or other agreement or instrument, filed as an exhibit to the Registration Statement or to the Company’s most recent Annual Report on Form 10-K, the Company’s Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2006 and June 30, 2006 or the Current Reports on Form 8-K of the Company incorporated by reference in the Prospectus (collectively, the “Incorporated Documents”), to which the Company is a party or by which it or its properties or assets may be bound or affected (the “Contracts”), or (c) any U.S. federal or state law, regulation or rule or, to our knowledge, any decree, judgment or order applicable to the Company or any of its Subsidiaries, except in the case of clause (b) for such breaches, violations, defaults or events which could not, individually or in the aggregate, have a Material Adverse Effect;

     (xvi) to our knowledge, there are no affiliate transactions, off-balance sheet transactions, contracts, licenses, agreements, leases or documents of a character which are required to be described in the Registration Statement, the Pre-Pricing Prospectus or the Prospectus or to be filed as an exhibit to the Registration Statement or any Incorporated Document which have not been so described or filed;

     (xviii) the Company is not and, after giving effect to the offering and sale of the Notes and the application of the proceeds thereof as described in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus, will not be required to register as an “investment company” as such term is defined in the Investment Company Act;

     (xix) the information in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus under the headings “Description of notes,” “Description of capital stock” and “Material U.S. federal income tax considerations,” insofar as such statements constitute summaries of documents or matters of law, and those statements in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus that are descriptions of contracts, agreements or other legal documents or of legal proceedings, or refer to statements of law or legal conclusions, are accurate in all material respects and present fairly the information required to be shown; and

     (xx) no person has the right, pursuant to the terms of any contract, agreement or other instrument described in or filed as an exhibit to the Registration Statement or the Incorporated Documents or otherwise known to us, to cause the Company to register under the Act any shares of Common Stock or shares of any other capital stock or other equity interest of the Company, or to include any such shares or interest in the Registration Statement or the offering contemplated thereby.

          In addition, we have participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants of the Company and representatives of the Underwriters at which the contents of the Registration Statement, the Pre-Pricing Prospectus, the Prospectus and the Permitted Free Writing Prospectus were discussed and, although we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Pre-Pricing Prospectus, the Prospectus or the Permitted Free Writing Prospectus (except as and to the extent stated in enumerated paragraphs (vii), (ix), and (xix) above), and have not made independent investigation of those statements, on the basis of the foregoing nothing has come to our attention that causes us to believe that (i) the Registration Statement at the Effective Time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Disclosure Package (as defined below), as of the Applicable Time (as defined below), included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) the Prospectus, as of the date of the Prospectus, or as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (it being understood that we express no view with respect to the Form T-1, the financial statements and related notes and schedules, and other financial data or statistical data derived therefrom, included or incorporated by reference in or omitted from the Registration Statement, the Disclosure Package or the Prospectus). As used herein, (A) “Disclosure Package” means the Pre-Pricing Prospectus together with the Permitted Free Writing Prospectus and (B) “Applicable Time” means ___ A.M./ P.M., New York City time, on October ___, 2006 (which you have informed us is at or prior to the time of the first sale of the Notes by the Underwriters).

          In rendering the opinions set forth in paragraphs (i) and (ii) above as to the good standing of the Company and as to qualification by it to do business as a foreign corporation, we relied without independent verification exclusively on the Opinion Certificates and certificates of public officials.

          In connection with the opinion in paragraph (vii) above relating to the capitalization of the Company, we draw your attention to (i) the fact that the articles of incorporation of Diodes Incorporated, a California corporation, contained preemptive rights and (ii) the information contained in the Prospectus under the heading “Risk factors — Risks related to our business — Our early corporate records are incomplete. As a result we may have difficulty assessing and defending against claims relating to rights to our common stock purporting to arise during periods for which our records are incomplete.”

           In rendering the opinion set forth in paragraph (xvii) above, please note that we have not conducted a docket search in any jurisdiction with respect to litigation that may be pending against the Company or any of its directors or officers.

          In addition to the foregoing, the opinions expressed above are subject to the following limitations, exceptions, qualifications and assumptions:

          1. We assumed that no party to the Underwriting Agreement will in the future take any discretionary action (including a decision not to act permitted by the Underwriting Agreement) that would cause the performance of the Underwriting Agreement to violate any applicable law, statute, rule or regulation; constitute a violation or breach of or default under any of the Contracts; or require an order, consent, permit or approval to be obtained from any government authority.

          2. We express no opinion as to whether the members of the Board of Directors of the Company have complied with their fiduciary duties in connection with the authorization and performance of the Transaction Documents, and the transactions contemplated thereby.

          3. We express no opinion as to matters governed by any laws other than the laws of the State of New York, the corporate law of the State of Delaware or the federal law of the United States of America. We express no opinion as to the laws of any other jurisdiction nor as to the statutes, administrative decisions, rules, regulations or requirements of any county, municipality, subdivision or local authority of any jurisdiction. We express no opinion as to whether the laws of any jurisdiction are applicable to the Transaction Documents or the transactions contemplated thereby.

          4. We express no opinion as to matters governed by federal and state laws and regulations governing: usury; broker-dealers, investment companies (except as set forth in paragraph (xviii)), and investment advisers; insurance; labor, employment (including, but not limited to, the Americans with Disabilities Act) and pension and employee benefits; antitrust and unfair competition; escheat; health and safety, environmental protection and hazardous substances; taxation (except as set forth in paragraph (xix) above); or patents, copyrights, trademarks, trade names and other intellectual property rights.

          This opinion is rendered as of the date first written above solely for your benefit in connection with the Underwriting Agreement and may not be relied on by you for any other purpose, or relied upon by, or furnished to, any other person without our prior written consent in each instance. Our opinion is expressly limited to the matters set forth above and we render no opinion, whether by implication or otherwise, as to any other matters relating to the Company. We assume no obligation to inform you of any facts, circumstances, events or changes in the law that may hereafter be brought to our attention that may alter, affect or modify the opinions expressed herein.

SPECIAL COUNSEL TO FABTECH

     We have acted as counsel for Diodes FabTech Incorporated, a Delaware corporation (the “Client”) in connection with the transactions (collectively, the “Transaction”) contemplated under that certain Underwriting Agreement dated as of October 5, 2006 (the “Underwriting Agreement”) between Diodes Incorporated (“Diodes”) and UBS Securities LLC as representative of the Underwriters named in Schedule A to the Underwriting Agreement. All capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Underwriting Agreement.

     Section 1. In rendering this opinion we have examined the following documents:

     1. The Underwriting Agreement;

     2. The Registration Statement;

     3. The Indenture;

     4. The Pre-Pricing Prospectus;

     5. The Prospectus;

     6. The Permitted Free Writing Prospectus identified on Annex A hereto (the “Permitted Free Writing Prospectuses”); and

     7. The certificate dated October ___, 2006 of the Client (the “Client Certificate”) attached hereto;

The documents identified in Items 1 — 7 are referred to herein as the “Transaction Documents.”

     In rendering the following opinions, as to factual matters that affect our opinions, we have, with your approval, relied on (and assumed the accuracy of) certificates, statements and other representations of the Client and others including certificates of public officials (the “Public Documents”). We have also reviewed the organizational documents of the Client, including its Certificate of Incorporation and Bylaws.

     Section 2. Based on the foregoing and in reliance thereon and on the assumptions and subject to the qualifications and limitations set forth in this opinion, we are of the opinion that:

          2.1. The Client is a corporation organized, validly existing and in good standing under the laws of the State of Delaware with corporate power and authority to own, lease and operate its properties and to conduct its business, as they are described in the

Registration Statement, the Pre-Pricing Prospectus, the Prospectus and any Permitted Free Writing Prospectus.

          2.2. The Client is qualified to do business as a foreign corporation and is in good standing in each jurisdiction where the ownership or leasing of its property or the conduct of its business, as described in the Registration Statement, the Pre-Pricing Prospectus, the Prospectus and any Permitted Free Writing Prospectus, requires such qualification except where the failure to so qualify would not, individually or in the aggregate, have a Material Adverse Effect. The opinion is based solely upon the Public Documents.

          2.3. To our knowledge, there is no action, suit, litigation, proceeding, inquiry or investigation at law or in equity or by or before any judicial or administrative court, public agency, body or other entity, pending or, threatened against or affecting the Client; or property or assets of the Client, which are required to be described in the Registration Statement, the Pre-Pricing Prospectus or Prospectus, but are not so described.

          2.4 The execution, delivery and performance of the Underwriting Agreement and the Indenture by Diodes, the issuance and sale of the Notes by Diodes and the consummation by Diodes of the transactions contemplated thereby do not and will not conflict with, result in any breach or violation of or constitute a default under (nor constitute any event which with notice, lapse of time or both would result in any breach of or constitute a default under) the Certificate of Incorporation or By-laws of the Client, or any indenture, mortgage, deed of trust, bank loan or credit agreement or other evidence of indebtedness, or any license, lease, contract or other agreement or instrument filed as an exhibit to the Registration Statement or Diodes’ most recent Annual Report on Form 10-K, Diodes’ Quarterly Reports on Form 10-Q for the quarters ended March 31, 2006 and June 30, 2006 or other current Reports on Form 8-K of Diodes incorporated by reference in the Prospectus, to which the Client is a party or by which it or any of its properties or assets may be bound or affected which have been identified in the Client Certificate or any decree, judgment or order applicable to the Client which has been identified in the Client Certificate.

          2.5. All of the outstanding shares of capital stock of the Client have been duly authorized and validly issued, are fully paid and non-assessable and, except as otherwise stated in the Registration Statement, the Pre-Pricing Prospectus, the Prospectus and any Permitted Free-Writing Prospectus, are owned by Diodes, and to our knowledge, no options, warrants or other rights to purchase, agreements or other obligations to issue or other rights to convert any obligation into shares of capital stock or ownership interests in the Client are outstanding;

     Section 3. Our opinions are based on the assumptions (upon which we have relied with your consent) and subject to the qualifications and limitations, set forth in this letter, including the following:

          3.1. We express no opinion as to any laws other than the federal laws of the United States, the laws of the state of Missouri and the General Corporation Law of the State of Delaware. We express no opinion as to the effect on the transaction of local law which shall include charters, ordinances, administrative opinions and rules and regulations of cities, counties,

towns, municipalities and special political subdivisions (whether created or enabled through legislative action at the federal, state or regional level).

          3.2. With respect to the opinion in Paragraph 2.5, our investigation has been limited solely to a review of Client’s Certificate of Incorporation and Bylaws, and copies of the minutes of the Client’s Board of Directors and copies of stock certificates (the “Client Documents”) furnished to us by the Client. We have assumed that the Client Documents are true, accurate and complete, accurately reflect the actions they purport to evidence, and that any consideration for stock issued by the Client was in fact duly paid and received.

          3.3. As to matters of fact, we have assumed all representations of the Client and the other parties in the Transaction Documents are true. When an opinion is stated to be “to our knowledge” or other words of similar import appear, the language refers to the actual knowledge of the attorneys within our firm who have rendered legal services in connection with our preparation of this opinion or who have been involved in substantive legal representation of the Client and does not indicate or imply any investigation or inquiry, of the Client or others, on our part except as otherwise expressly stated.

          3.4 We express no opinion with respect to the application or effect of the securities or environmental laws, regulations or codes of the State of Missouri or any other jurisdiction, except as set forth in Paragraph 2.3.

          3.5 Our review of the Registration Statement, the Pre-Pricing Prospectus, the Prospectus and any Permitted Free Writing Prospectus was limited in its entirety to those portions of the Registration Statement, the Pre-Pricing Prospectus, the Prospectus and any Permitted Free Writing Prospectus describing the properties and the business of the Client, and only to the extent necessary to provide the opinion in Paragraph 2.1. No further opinion with regard to the Registration Statement, the Pre-Pricing Prospectus, the Prospectus or any Permitted Free Writing Prospectus is expressed.

          3.6. This opinion is limited to the matters specifically stated in this letter, and no further opinion is to be implied or may be inferred beyond the opinions specifically stated herein. Unless otherwise stated herein, we have made no independent investigation regarding factual matters. This opinion is based solely on the state of the law as of the date of this opinion, and we specifically disclaim any obligation to monitor any of the matters stated in this opinion or to advise the persons entitled to rely on this opinion of any change in law or fact after the date of this opinion which might affect any of the opinions stated herein.

     This opinion is rendered solely for your benefit and the benefit of your counsel, in connection with the transactions contemplated by the Underwriting Agreement and may not be released to or relied upon by any other person or for any other purpose without our prior written consent.

Capitalized terms used in this opinion as defined terms which are not otherwise defined herein but which are defined in the Agreement shall have the same meanings herein as are given to them in the Agreement.

          In rendering this opinion, we have conducted investigations in and collected documents from the relevant administrations of industry and commerce in charge of registration of the Subsidiaries respectively. In addition, we have examined, and have relied as to matters of fact upon, originals, or duplicates or certified or conformed copies, of such corporate records, agreements, documents and other instruments and such certificates or comparable documents or written or oral statements of public officials and of officers and representatives of the Subsidiaries and have made such other investigations, as we have deemed relevant and necessary, in connection with the opinions hereinafter set forth. In examinations of the aforesaid documents, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity of all natural persons who have executed any documents, the authenticity of all original documents, and the conformity to original documents of all documents submitted to us as copies.

          Based upon the foregoing, we are of the opinion as follows:

     (i) each of the Subsidiaries has been duly organized and is validly existing in good standing under the laws of its jurisdiction of incorporation, with full corporate power and authority to own, lease and operate its properties and to conduct its business as described in their business licenses issued by the Administration of Industry and Commerce of the People’s Republic of China (each, a “Business License”);

     (ii) each of the Subsidiaries is duly qualified to do business as a Chinese corporation and each of the Subsidiaries has taken all necessary action to ensure that they can validly conduct their business in all jurisdictions that they currently do business in.

     (iii) all of the registered capital of each of the Subsidiaries has been duly approved, is fully paid and nonassessable and is 95% owned by the

Company, in each case subject to no security interest, other encumbrance or adverse claim; and to our knowledge, no options, warrants or other rights to purchase, agreements or other obligations to issue or other rights to convert any obligation into the registered capital or ownership interests in the Subsidiaries are outstanding;

     (iv) the execution, delivery and performance of the Agreement and the Indenture by the Company, the issuance and sale of the Notes by the Company and the consummation by the Company of the transactions contemplated thereby do not conflict with, result in any breach or violation of or constitute a default under (nor constitute any event which with notice, lapse of time or both would result in any breach of or constitute a default under) the Business License or articles of association of either of the Subsidiaries, or any indenture, mortgage, deed of trust, bank loan or credit agreement or other evidence of indebtedness, or any license, lease, contract or other agreement or instrument to which either of the Subsidiaries is a party or by which either of them or any of their respective properties or assets may be bound or affected, or any law of the People’s Republic of China, regulation or rules of state or local governments, or any decree, judgment or order applicable to either of the Subsidiaries;

     (v) to our knowledge, neither of the Subsidiaries is in breach or violation of or in default under (nor has any event occurred which with notice, lapse of time or both would result in any breach of, or constitute a default under or give the holder of any indebtedness (or a person action on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a part of such indebtedness under) its respective Business License or articles of association, or any indenture, mortgage, deed of trust, bank loan or credit agreement or other evidence of indebtedness, or any license, lease, contract or other agreement or instrument to which either of the Subsidiaries is a party or by which either of them or any of their respective properties or assets may be bound or affected, or any law of the People’s Republic of China, regulation or rules of state or local governments, or any decree, judgment or order applicable to either of the Subsidiaries;

     (vi) to our knowledge, there are no actions, suits, claims, investigations or proceedings pending, threatened or contemplated to which either of the Subsidiaries or any of their respective directors or officers is a party or to which any of their respective properties or assets is subject at law, before or by any national, provincial or local governmental or regulatory commission, board, body, authority or agency of the People’s Republic of China; and

     (vii) the information incorporated by reference in the Registration Statement, the Pre-Pricing Prospectus, the Prospectus and any Permitted Free Writing Prospectus from the Company’s Annual Report on Form 10-K for the year ended December 31, 2005 under the heading “Risk factors — We may not continue to receive preferential tax treatment in China, thereby increasing our income tax expense and reducing our net income.” and under the heading

“Management’s discussion and analysis of financial condition and results of operations — Overview — Income tax provision,” insofar as such statements constitute a summary of Chinese tax laws and applicable tax rates related to each Subsidiary, they are accurate and fair statements of such information and to our knowledge the Subsidiaries’ activities of paying taxes are not so far challenged by related Chinese tax authorities.

          We are admitted to practice only in the People’s Republic of China and express no opinion as to matters governed by any laws other than the laws of the People’s Republic of China.

          This opinion is given as of the date hereof and is expressly limited to the matters stated herein. No opinion is implied or may be inferred beyond what is expressly stated in this letter.

     (iv) The execution, delivery and performance of the Agreement and the Indenture by the Company, the issuance and sale of the Notes by the Company and the consummation by the Company of the transactions contemplated thereby do not and will not conflict with, result in any breach or violation of or constitute a default under (nor constitute any event which with notice, lapse of time or both would result in any breach of or constitute a default under) Anachip’s business license issued by the Ministry of Economic Affairs of the government of the ROC (the “Business License”) or the articles of association of Anachip, or any indenture, mortgage, deed of trust, bank loan or credit agreement or other evidence of indebtedness, or any license, lease, contract or other agreement or instrument to which Anachip is a party or by which it or any of its properties or assets may be bound or affected, or any national or local law, regulation or rule of Taiwan, or any decree, judgment or order applicable to it;

local governmental or regulatory commission, board, body, authority or agency of ROC.

The foregoing opinions are subject to the following:

          We are admitted to practice law in the Republic of China (Taiwan). We have made no investigation of the law of any jurisdiction other than the ROC and do not express or imply any opinion as to matters governed by any laws other than the laws of the Republic of China.

          This opinion is given as of the date hereof and is expressly limited to the matters stated herein. No opinion is implied or may be inferred beyond what is expressly stated in this letter. We disclaim any duty to supplement this opinion by reason of any change occurring after the date hereof in law or facts.

          This opinion is rendered solely for your benefit and solely in connection with the closing of the transactions contemplated by the Agreement; it may not be relied upon by you for any other purpose, nor may it be furnished to, quoted to or relied upon by any other person or entity.

          We have assumed the genuineness of photocopies of the documents and provided to us by the Company and Anachip. We have assumed that all signatures, seals and chops are genuine, that all such documents submitted to us are complete and accurately conform to the originals and that such originals themselves are authentic, complete and accurate.

          We have assumed that the final executed versions of the Agreement, the Registration Statement and the Pre-Pricing Prospectus and related documents for the contemplated transaction, including all the attachments, annexes, exhibits and schedules will, substantially and materially conform to the drafts provided to us.

          We have assumed that all parties have the capacity, power and authority to enter into the Agreement, Prospectus, Registration Statement and the Pre-Pricing Prospectus and related documents for the contemplated transaction, the final executed documents will be duly authorized, executed and delivered by such parties and the obligations of all parties under any applicable law other than ROC law and of all parties other than the Company and Anachip under ROC law are binding.

          The ROC does not have a “good standing” concept in the U.S. sense, such that no government agency issues the equivalent of a U.S. good standing certificate for ROC companies. The use of the term “good standing” in our opinion is based on the information reported on the website of the Commerce Industrial Service Portal (http://gcis.nat.gov.tw/new_open_system.jsp) indicating that Anachip has not failed to make any required filing with any ROC governmental authority and that it has not had any administrative order or court judgment made against it which would cause it to cease to exist under the laws of the ROC., whether by dissolution, liquidation, bankruptcy or otherwise.

          We have not made any special investigation, except to review of the above Documents, and have rendered this opinion based on the information provided to us in the course

of our representation as special counsel to the Company and Anachip and the written officer’s certificate of C.H. Chen dated as of the date hereof.

          We express no opinion with respect to any part of the Company’s securities matters set forth in the Prospectus, the Registration Statement and related documents and issue no opinion on any public offering matters.
