EXPLANATORY NOTE This Post-effective Amendment No. 1 (the "Amendment") to the Registration Statement on Form S-3 (No. 33-90392) (the "Registration Statement") is being filed pursuant to Rule 414 under the Securities Act of 1933, as amended (the "Securities Act") by PMC-Sierra, Inc., a Delaware corporation incorporated in May 1997 (the "Company"). The Company is the successor to PMC-Sierra, Inc. (formerly named Sierra Semiconductor Corporation), a California corporation ("Sierra"), following a statutory merger (the "Merger") for the purpose of changing Sierra's state of incorporation from California to Delaware, effective as of July 10, 1997. Prior to the Merger, the Company had no assets or liabilities other than nominal assets or liabilities. In connection with the Merger, the Company succeeded by operation of law to all of the assets and liabilities of Sierra. The Merger was approved by the shareholders of Sierra at a meeting for which proxies were solicited pursuant to Section 14(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Except as modified by this Amendment, the Company, by virtue of this Amendment, expressly adopts the Registration Statement as its own registration statement for all purposes of the Securities Act and the Exchange Act. Additional information necessary to reflect any material change made in connection with or resulting from the Merger is set forth below. INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE In addition to the documents which have been incorporated by reference by the Company's predecessor and made a part of the Prospectus, the following documents, which have been filed by the Company with the Securities and Exchange Commission (the "Commission"), are incorporated by reference and made a part of this Prospectus: (i) the Quarterly Report on Form 10-Q for the quarter ended June 30, 1997, and the Current Report on Form 8-K filed on August 8, 1997, filed pursuant to the Exchange Act; (ii) the description of the Company's Capital Stock set forth in Amendment No. 2 to the Registration Statement on Form S-3 (File No. 333-15519); and (iii) all reports, definitive proxy statement and other documents filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of this Prospectus and prior to the termination of the Offering. PART II INFORMATION NOT REQUIRED IN PROSPECTUS Item 15 Indemnification of Directors and Officers. ------------------------------------------ The Certificate of Incorporation of the Company eliminates the liability of directors to the Company for monetary damages for breach of fiduciary duty as a director to the fullest extent permissible under Delaware law, as such law exists currently or as it may be amended in the future. Under Delaware law, such provision may not eliminate or limit director monetary liability for: (a) breaches of the director's duty of loyalty to the Company or its stockholders; (b) acts or omissions not in good faith or involving intentional misconduct or knowing violations of law; (c) the payment of unlawful dividends or unlawful stock repurchases or redemptions; or (d) transactions in which the director received an improper personal benefit. Such limitation of liability provisions also may not limit a director's liability for violation of, or otherwise relieve the Company or its directors from the necessity of complying with, federal or state securities laws, or affect the availability of non-monetary remedies such as injunctive relief or rescission. The Company's Bylaws provide that the Company shall indemnify its directors and officers and may indemnify its employees and other agents to the fullest extent permitted by law. The Company believes that indemnification under its Bylaws covers at least negligence and gross negligence on the part of indemnified parties. The Company's Bylaws also permit the Company to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in such capacity, regardless of whether the Company would have the power to indemnify him or her against such liability under the General Corporation Law of Delaware. The Company currently has secured such insurance on behalf of its officers and directors. The Company has entered into agreements to indemnify its directors and officers, in addition to indemnification provided for in the Company's Bylaws. Subject to certain conditions, these agreements, among other things, indemnify the Company's directors and officers for certain expenses (including attorney's fees), judgments, fines and settlement amounts incurred by any such person in any action or proceeding, including any action by or in the right of the Company, arising out of such person's services as a director or officer of the Company, any subsidiary of the Company or any other company or enterprise to which the person provides services at the request of the Company.
