3 Page 3 of 5 ITEM 1. SECURITY AND ISSUER This Schedule 13D Amends a Schedule 13D filed by Nicholas J. Cedrone in December 1995. The class of equity securities to which this Statement on Schedule 13D relates is the Common Stock, $1.00 par value per share (the "Common Stock"), of Cohu, Inc. (the "Issuer" or "Cohu"), a Delaware corporation, with its principal executive offices located at 5755 Kearny Villa Road in San Diego, California 92123. Principal Executive Officers of Issuer: Charles A. Schwan, President & CEO 5755 Kearny Villa Road, San Diego, CA John H. Allen, Vice President & CFO 5755 Kearny Villa Road, San Diego, CA ITEM 2. IDENTITY AND BACKGROUND This Schedule 13D is being filed by Nicholas J. Cedrone, an individual ("Cedrone"). Cedrone has a business address at One Monarch Drive, Littleton, Massachusetts 01460. Cedrone is employed as a Vice President of Daymarc, Inc., a wholly-owned subsidiary of Cohu, Inc., which designs, develops and manufactures test handling equipment for the semiconductor industry and is located at One Monarch Drive, Littleton, Massachusetts 01460. Cedrone is the founder and sole shareholder of Daymarc Corporation (See Item 3). During the last five years, Cedrone has not been (a) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. Cedrone is a citizen of the United States. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION The Schedule 13D filed by Cedrone in December 1995 related to the issuance of 560,000 shares (all share amounts included herein have been adjusted for Cohu's two-for-one stock split effective June 6, 1995) of Common Stock of Cohu, Inc. $1.00 par value, to Cedrone. These shares were issued to Cedrone pursuant to the Agreement and Plan of Merger dated June 16, 1994 by and among Cohu, Inc., Daymarc Corporation, Cohu Acquisition Corporation, Nicholas J. Cedrone and Melvyn Bosch (the "Merger Agreement"). The Merger Agreement, which was included as Exhibit 1 to the Schedule 13D filed in December 1995, provided that additional performance-based consideration would be payable to Cedrone in Cohu Common Stock and cash through June 1998. During the four-year period ended June 1998, Cohu issued a total of 143,819 shares of its Common Stock to Cedrone, including 17,698 shares issued on February 13, 1998, pursuant to the Merger Agreement.

4 Page 4 of 5 On July 21, 1994 the Issuer granted Cedrone options to purchase 20,000 shares of Cohu Common Stock. During the period from October 1995 to December 1998 Cedrone acquired 20,000 shares of Cohu Common Stock for cash upon the exercise of an equivalent number of stock options. During 1998 Cedrone donated 4,000 shares of Cohu Common Stock to a nonprofit organization. No part of the consideration used by Cedrone for the acquisition of Cohu shares of Common Stock was borrowed. ITEM 4. PURPOSE OF TRANSACTION This Statement relates to (i) the shares of Cohu Common Stock issued to Cedrone by the Issuer pursuant to the Merger Agreement and (ii) the subsequent acquisition and disposition of shares of Cohu Common Stock as described in Item 3 above. The Shares were issued to Cedrone by the Issuer as consideration for the Merger Agreement. Pursuant to the Merger Agreement, Daymarc Corporation merged with and into Cohu Acquisition Corporation, a wholly-owned subsidiary of the Issuer, the separate existence of Daymarc Corporation ceased and Cohu Acquisition Corporation, as the surviving corporation in the Merger, changed its name to Daymarc, Inc. Other than as described above, Cedrone has no plans or proposals which relate to, or may result in, any of the matters listed in Items 4(a)-(j) of Schedule 13D (although Cedrone reserves the right to develop such plans). ITEM 5. INTEREST IN SECURITIES OF THE ISSUER As a result of the issuance of shares of Cohu Common Stock pursuant to the Merger Agreement and subsequent exercises of stock options, Cedrone may be deemed to be the beneficial owner of 719,819 shares of Cohu Common Stock, which would represent approximately 7.32% of the shares of Cohu Common Stock outstanding (based on the number of shares of Common Stock outstanding on March 31, 1999). Cedrone has sole voting and dispositive power with respect to such shares. Cedrone has not acquired or disposed of any shares of Cohu Common Stock during the past sixty (60) days. ITEM 6. CONTRACT, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER Except for the Merger Agreement, Cedrone has no contract, arrangement, understanding or relationship (legal or otherwise) with any person with respect to any securities of the Issuer, including, but not limited to, transfer or voting of any securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
