Ladies and Gentlemen:

Diodes Incorporated, a Delaware corporation (the “Company”), proposes to issue and sell, and Lite-On Semiconductor Corporation (the “Selling Stockholder”), a corporation organized under the laws of the Republic of China (Taiwan) (“Taiwan”), proposes to sell, to the underwriters named in Schedule A annexed hereto for whom UBS Securities LLC (“UBS”), A.G. Edwards & Sons, Inc., C.E. Unterberg, Towbin, LLC, Raymond James & Associates, Inc. and WR Hambrecht + Co, LLC (together, the “Managing Underwriters”) are acting as representatives, an aggregate of 2,500,000 shares (the “Firm Shares”) of Common Stock, $0.66²/3 par value per share (the “Common Stock”), of the Company, of which 1,750,000 shares are to be issued and sold by the Company and 750,000 shares are to be sold by the Selling Stockholder. 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 375,000 shares of Common Stock (the “Additional Shares”). The Firm Shares and the Additional Shares are hereinafter collectively sometimes referred to as the “Shares.” The Shares are described in the Prospectus which is referred to below.

The Company has 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. 333-127833) including a prospectus, relating to the Shares, which 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”). The Company has furnished to you, for use by the Underwriters and by dealers, copies of one or more preliminary prospectuses and the documents incorporated by reference therein (each thereof, including the documents incorporated therein by reference, being herein called a “Preliminary Prospectus”) relating to the Shares. Except where the context otherwise requires, the registration statement, as amended when it becomes effective, including all documents filed as a part thereof or incorporated by reference therein, and including

any information contained in a prospectus subsequently filed with the Commission pursuant to Rule 424(b) under the Act and deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430(A) under the Act and also including any registration statement filed pursuant to Rule 462(b) under the Act, is herein called the “Registration Statement,” and the prospectus, including all documents incorporated therein by reference, in the form 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) or, if no such filing is required, the form of final prospectus included in the Registration Statement at the time it became effective, is herein called the “Prospectus.” As used herein, “business day” shall mean a day on which the Nasdaq National Market (the “NASDAQ”) is open for trading.

The Company, the Selling Stockholder 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, and the Selling Stockholder agrees to sell, severally and not jointly, to the respective Underwriters, and each of the Underwriters, severally and not jointly, agrees to purchase from the Company and the Selling Stockholder, the respective number of Firm Shares (subject to such adjustment as you may determine to avoid fractional shares) which bears the same proportion to the number of Firm Shares to be sold by the Company or by the Selling Stockholder, as the case may be, as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule A attached hereto, subject to adjustment in accordance with Section 10 hereof, in each case at a purchase price of $ per Share. The Company and the Selling Stockholder are each advised by you that the Underwriters intend (i) to make a public offering of their respective portions of the Firm Shares as soon after the effective date of the Registration Statement as in your judgment is advisable and (ii) initially to offer the Firm Shares 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 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 number of Firm Shares to be purchased by each of them, all or a portion of the Additional Shares as may be necessary to cover over-allotments made in connection with the offering of the Firm Shares, at the same purchase price per share to be paid by the Underwriters to the Company and the Selling Stockholder for the Firm Shares. This option may be exercised by UBS on behalf of the several Underwriters at any time and from time to time on or before the thirtieth day following the date hereof, by written notice to the Company. Such notice shall set forth the aggregate number of Additional Shares as to which the option is being exercised, and the date and time when the Additional Shares are to be delivered (such date and time being herein referred to as the “additional time of purchase”); provided, however, that the additional time of purchase shall not be earlier than the time of purchase (as defined below) nor earlier than the second business day after the date on which the option shall have been exercised nor later than the tenth business day after the date on which the option shall have been exercised. The number of Additional Shares to be sold to each Underwriter shall be the number which bears the same proportion to the

aggregate number of Additional Shares being purchased as the number of Firm Shares set forth opposite the name of such Underwriter on Schedule A hereto bears to the total number of Firm Shares (subject, in each case, to such adjustment as you may determine to eliminate fractional shares), subject to adjustment in accordance with Section 10 hereof. Pursuant to a power of attorney, which shall be reasonably satisfactory to counsel for the Underwriters (the “Power of Attorney”), granted by the Selling Stockholder Keh-Shew Lu and Carl C. Wertz will act as representatives of the Selling Stockholder. The foregoing representatives (the “Representatives of the Selling Stockholder”) are authorized, on behalf of the Selling Stockholder, to execute any documents necessary or desirable in connection with the sale of the Shares to be sold hereunder by the Selling Stockholder, to make delivery of the certificates of such Shares, to receive the proceeds of the sale of such Shares, to give receipts for such proceeds, to pay therefrom the expenses to be borne by the Selling Stockholder in connection with the sale and public offering of the Shares, to distribute or cause to be distributed the balance of such proceeds to the Selling Stockholder, to receive notices on behalf of the Selling Stockholder and to take such other action as may be necessary or desirable in connection with the transactions contemplated by this Agreement.

2. Payment and Delivery. Payment of the purchase price for the Firm Shares shall be made to the Company and the Selling Stockholder by Federal Funds wire transfer, against delivery of the certificates for the Firm Shares 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 , 2005 (unless another time shall be agreed to by you and the Company and the Representatives of the Selling Stockholder or unless postponed in accordance with the provisions of Section 10 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 Shares 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 Shares shall be made at the additional time of purchase in the same manner and at the same office as the payment for the Firm Shares. Electronic transfer of the Additional Shares shall be made to you at the additional time of purchase in such names and in such denominations as you shall specify.

Deliveries of the documents described in Section 8 hereof with respect to the purchase of the Shares 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 Shares or the Additional Shares, as the case may be.

change or any development involving a prospective material adverse change in the business, properties, management, financial condition or results of operation of the Company and the Subsidiaries taken as a whole, which would, in UBS’ judgment or in the judgment of such group of Underwriters, make it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares on the terms and in the manner contemplated in the Registration Statement and the Prospectus, 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 the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in UBS’ judgment or in the judgment of such group of Underwriters makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Shares on the terms and in the manner contemplated in the Registration Statement and the Prospectus, 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 or any group of Underwriters elects to terminate this Agreement as provided in this Section 9, the Company, the Representatives of the Selling Stockholder and each other Underwriter shall be notified promptly in writing.

If the sale to the Underwriters of the Shares, 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 or the Selling Stockholder, as the case may be, shall be unable to comply with any of the terms of this Agreement, the Company or the Selling Stockholder, as the case may be, shall not be under any obligation or liability under this Agreement (except to the extent provided in Sections 5(n), 7 and 11 hereof), and the Underwriters shall be under no obligation or liability to the Company and the Selling Stockholder under this Agreement (except to the extent provided in Section 9 hereof) or to one another hereunder.

of Firm Shares agreed to be purchased by all such defaulting Underwriters, as hereinafter provided. Such Shares 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 Shares shall be taken up and paid for by all non-defaulting Underwriters pro rata in proportion to the aggregate number of Firm Shares set opposite the names of such non-defaulting Underwriters in Schedule A.

Without relieving any defaulting Underwriter from its obligations hereunder, the Company and the Selling Stockholder agrees with the non-defaulting Underwriters that it will not sell any Firm Shares hereunder unless all of the Firm Shares 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 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 and the Prospectus 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 10 with like effect as if such substituted Underwriter had originally been named in Schedule A.

If the aggregate number of Firm Shares which the defaulting Underwriter or Underwriters agreed to purchase exceeds 10% of the total number of Firm Shares 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 Shares 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 Under-writer 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.

11. Indemnity and Contribution.

(a) The Company and the Selling Stockholder jointly and severally agree 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 in a Prospectus (the term

Prospectus for the purpose of this Section 11 being deemed to include any Preliminary Prospectus, the Prospectus and the Prospectus as amended or supplemented 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 in either such Registration Statement or such Prospectus or necessary to make the statements made 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 such Registration Statement or such Prospectus or arises out of or is based upon any omission or alleged omission to state a material fact in connection with such information required to be stated in such Registration Statement or such Prospectus or 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 any material fact contained in any audio or visual materials provided by the Company or based upon written information furnished by or on behalf of the Company including, without limitation, slides, videos, films or tape recordings used in connection with the marketing of the Shares, provided, further, that the Selling Stockholder shall not be responsible for losses, damages, expenses, liabilities or claims, under this paragraph or paragraph (e) below or as a result of any breach of this Agreement, for an amount in excess of the proceeds to be received by the Selling Stockholder (before deducting expenses) from the sale of Shares hereunder. Additionally, the Company shall indemnify, defend and hold harmless the Selling Stockholder to the same extent as the Company is obligated to indemnify, defend and hold harmless the Underwriters pursuant to this Section 11(a), subject to the same limitations as set forth herein.

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 or the Selling Stockholder pursuant to the foregoing paragraph, such Underwriter or such person shall promptly notify the Company and the Representatives of the Selling Stockholder in writing of the institution of such Proceeding and the Company or the Selling Stockholder, as the case may be, 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 or the Representative of the Selling Stockholder shall not relieve the Company or the Selling Stockholder from any liability which the Company or the Selling Stockholder may have to any Underwriter or any such person or otherwise, except where such omission results in material prejudice to the Company or the Selling Stockholder that affects the rights of the Company or the Selling Stockholder. 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 or the Selling Stockholder in connection with the defense of such Proceeding or the Company or the Selling Stockholder 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 or the Selling Stockholder (in which case the Company or the Selling Stockholder 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 or the Selling Stockholder and paid as incurred (it being understood, however, that the Company or the Selling Stockholder 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 or the Selling Stockholder 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 or the Selling Stockholder, the Company or the Selling Stockholder 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 11(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, the Selling Stockholder and any person who controls the Company or the Selling Stockholder 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, the Selling Stockholder 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 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 in a Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in connection with such information required to be stated in such Registration Statement or such Prospectus or necessary to make such information not misleading.

If any Proceeding is brought against the Company, the Selling Stockholder or any such person in respect of which indemnity may be sought against any Underwriter pursuant to the foregoing paragraph, the Company, the Selling Stockholder 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, the Selling Stockholder or any such person or otherwise, except to such extent as such Underwriter is materially prejudiced by such omission. The Company, the Selling Stockholder 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, the Selling Stockholder 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, the Selling Stockholder 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 11 is unavailable to an indemnified party under subsections (a) and (b) of this Section 11 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 Shares 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 and the Selling Stockholder 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 and the Selling Stockholder 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 Selling Stockholder and the total underwriting discounts and commissions received by the Underwriters, bear to the aggregate public offering price of the Shares. The relative fault of the Company and the Selling Stockholder 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 and/or the Selling Stockholder 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, the Selling Stockholder and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 11 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 11, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares 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 11 are several in proportion to their respective underwriting commitments and not joint.

(e) The indemnity and contribution agreements contained in this Section 11 and the covenants, warranties and representations of the Company and the Selling Stockholder 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, any Selling Stockholder 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 Shares. The Company, the Selling Stockholder and each Underwriter agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Company or the Selling Stockholder, against any of the Company’s or Selling Stockholder’s officers or directors, as the case may be, in connection with the issuance and sale of the Shares, or in connection with the Registration Statement or the Prospectus.

12. Information Furnished by the Underwriters. The statements set forth in the last paragraph on the cover page of the Prospectus and the statements set forth in the second, third and last 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” 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 11 hereof.

13. Notices. Except as otherwise herein provided, all statements, requests, notices and agreements shall be in writing or by telegram and, if to the Underwriters, shall be sufficient in all respects if delivered or sent to UBS Securities LLC, 299 Park Avenue, New York, N.Y. 10171-0026, Attention: Syndicate Department, with a copy to Simpson Thacher & Bartlett LLP, 3330 Hillview Avenue, Palo Alto CA 94304, Attention William B.

Menard, Esq.

14. 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.

15. 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 and the Selling Stockholder consents to the jurisdiction of such courts and personal service with respect thereto. The Company and the Selling Stockholder hereby consent 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 UBS or any indemnified party. Each of UBS, the Selling Stockholder 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 and the Selling Stockholder agree 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. The Selling Stockholder hereby appoints, without power of revocation, CT Corporation System, at its offices located at 111 Eighth Avenue, New York, New York 1001, as its agent to accept and acknowledge on its behalf service of any and all process which may be served in any action, proceeding or counterclaim in any way relating to or arising out of this Agreement, and it being understood that the designation and appointment of CT Corporation System as its agent shall become effective immediately without any further action on the part of the Selling Stockholder. The Selling Stockholder represents to each Underwriter that it has notified CT Corporation System of such designation and appointment and that CT Corporation System has accepted the same. The Selling Stockholder further agrees that, to the extent permitted by law, proper service of process upon CT Corporation System (or its successors as agent for service of process) and written notice of said service to the Selling Stockholder pursuant to Section 13, shall be deemed in every respect effective service of process upon the Selling Stockholder in any such suit or proceeding. The Selling Stockholder agrees that the failure of any such designee, appointee and agent to give any notice of such service to them shall not impair or affect in any way the validity of such service or any judgment rendered in any action or proceeding based thereon. Nothing herein shall in any way be deemed to limit the ability of the Underwriters and the other persons referred to in Section 11 to serve any such legal process, summons, notices and documents in any other manner permitted by applicable law or to obtain jurisdiction over the Selling Stockholder or bring actions, suits or proceedings against the Selling Stockholder in such other jurisdictions, and in such manner, as may be permitted by applicable law. The Selling Stockholder hereby irrevocably and unconditionally waives, to the fullest extent permitted by law, any objection that they may now or hereafter have to the laying of venue of any of the aforesaid actions, suits or proceedings arising out of or in connection with this Agreement brought in any New York State or U.S. federal court specified in this Section 15 and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in such court has been brought in an inconvenient forum.

16. Parties at Interest. The Agreement herein set forth has been and is made solely for the benefit of the Underwriters, the Selling Stockholder and the Company and to the extent provided in Section 11 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.

17. 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.

18. Successors and Assigns. This Agreement shall be binding upon the Underwriters, the Selling Stockholder and the Company and their successors and assigns and any

successor or assign of any substantial portion of the Company’s, the Selling Stockholder’s and any of the Underwriters’ respective businesses and/or assets.

19. 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.

The Company and the Selling Stockholder hereby acknowledge that the Underwriters are acting solely as an underwriter 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 Underwriting 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, the Selling Stockholder or any other person in connection with any activity that the Underwriters may undertake or has 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 and the Selling Stockholder, either in connection with the transactions contemplated by this Underwriting Agreement or any matters leading up to such transactions, and the Company and the Selling Stockholder hereby confirm their understanding and agreement to that effect. The Company, the Selling Stockholder 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 or the Selling Stockholder 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 or the Selling Stockholder. The Company and the Selling Stockholder hereby waive and release, to the fullest extent permitted by law, any claims that the Company and the Selling Stockholder may have against the Underwriters with respect to any breach or alleged breach of any fiduciary or similar duty to the Company or the Selling Stockholder in connection with the transactions contemplated by this Underwriting Agreement or any matters leading up to such transactions.

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”), and Lite-On Semiconductor Corporation, a corporation formed under the laws of the Republic of China (Taiwan) (the “Selling Stockholder”), 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) an aggregate of 2,500,000 shares of the Common Stock, $0.66²/3 par value per share, of the Company (the “Firm Shares”), of which 1,750,000 shares are to be issued and sold by the Company and 750,000 shares are to be sold by the Selling Stockholder pursuant to that certain Underwriting Agreement, dated as of September ___, 2005, by and among the Company, the Selling Stockholder and the Underwriters (the “Underwriting Agreement”) and (ii) up to 375,000 additional shares of the Common Stock of the Company (the “Additional Shares”), all of which would be sold by the Company, pursuant to the Underwriting Agreement, at the Underwriters’ option solely to cover over-allotments. This opinion is given to you pursuant to Sections 8(a) and (f) 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 Underwriting Agreement, the Power of Attorney and the Custody Agreement (the “Transaction Documents”), the certificates of certain officers of the Company and the Selling Stockholder (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 Underwriting Agreement) 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 and the Selling Stockholder), (iii) the enforceability and binding nature of the obligations of the parties to such documents and (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. 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.

B-1

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, 2003.

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 and the 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 or the Prospectus (except as and to the extent stated in enumerated paragraphs (vi), (viii) and (xviii) 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 the Registration Statement or any amendment thereto (including the Exchange Act Documents), at the time such Registration Statement or amendment became effective, 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, or that the Prospectus (including the Exchange Act Documents) or any supplement thereto at the date of such Prospectus or such supplement, 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, in light of the circumstances under which they were made, not misleading (it being understood that we express no opinion with respect to 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 or the Prospectus or any supplement or amendment thereto).

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 (vi) 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 — 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.”

B-6

In rendering the opinion set forth in paragraph (xi) above relating to the effectiveness of the Registration Statement, we relied exclusively on the oral representation of the Commission obtained on September ___, 2005.

In rendering the opinion set forth in paragraph (xvi) 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 rendering the opinion set forth in paragraph (xxii) above, we have assumed that (i) The Depository Trust Company (“DTC”) is a “securities intermediary” as defined in Section 8-102 of the Uniform Commercial Code as in effect in the State of New York (the “New York UCC”), and the State of New York is the “securities intermediary’s jurisdiction” of DTC for purposes of Section 8-110 of the New York UCC, (ii) the Shares to be sold by the Selling Stockholder are registered in the name of DTC or its nominee, and DTC or another person on behalf of DTC maintains possession of certificates representing those Shares, (iii) DTC indicates by book entries on its books that security entitlements with respect to the Shares to be sold by the Selling Stockholder have been credited to the Underwriters’ securities accounts and (iv) the Underwriters are purchasing the Shares to be sold by the Selling Stockholder without notice of any adverse claim (within the meaning of the New York UCC).

In rendering the opinions set forth in paragraph (xx) and (xxiii), we have relied without independent investigation exclusively on (i) the Power of Attorney and assumed that each of the certifications, representations and warranties made by the Selling Stockholder therein are true and correct as if made on the date hereof and (ii) the legal opinion to you of Huang & Partners Law Offices, special counsel to the Selling Stockholder, to the effect that the Transaction Documents have been duly executed and delivered by or on behalf of the Selling Stockholder and each of the Representatives of the Selling Stockholder has been duly authorized to execute and deliver on behalf of the Selling Stockholder the Transaction Documents.

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 compliance with any federal or state antitrust statutes, rules or regulations, including without limitation the Hart-Scott-Rodino Antitrust Improvements Act of 1976.

3. 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.

B-7

4. 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.

5. 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 (xvi)), 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 (xviii) 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 or the Selling Stockholder. 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.

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 or Prospectus, but are not so described.

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 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 as copies. 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 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.

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”);

(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 shares of the registered capital or ownership interests in the Subsidiaries are outstanding;

(iv) the execution, delivery and performance of the Agreement by the Company, the issuance and sale of the Shares by the Company and the consummation by the Company of the transactions contemplated hereby 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 in the Registration Statement and the Prospectus 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 “Management’s discussion and analysis of financial condition

D-2

and results of operations — Overview — Financial 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.
