Oliver and Clifford Press, who share the power to vote and the power to direct the disposition of the 244,118 shares of common stock, par value $0.01 per share (the "Shares"), of Coherent, Inc., a Delaware corporation, owned, as of January 31, 2008, by Davenport Partners, L.P., a Delaware limited partnership, the 2,280,771 Shares owned by JE Partners, a Bermuda partnership, and the 79,200 Shares owned by Oliver Press Master Fund LP, a Cayman limited partnership. Item 4. Purpose of Transaction. ---------------------- Item 4 is hereby amended by deleting Item 4 in its entirety and by substituting the following in lieu thereof: The Partnerships purchased the Shares because OPP, as their investment adviser, believed the Shares to be undervalued. OPP believes that the Company has available to it a number of strategic initiatives that will enhance its value, and has engaged in discussions with the Board and management of the Company to review these initiatives. On January 31, 2008 the Filing Parties entered into an agreement (the "Agreement") with the Company pursuant to which, among other things, the Company agreed to nominate Clifford Press for election to the Company's Board of Directors at the Company's annual meeting currently scheduled for March 19, 2008, and to elect him to the Board of Directors within two days in the event that the annual meeting is not held on or before that date. In the event that the Filing Parties cease to hold beneficially at least 50% of the common stock of the Company that the Filing Parties currently hold as a group, Mr. Press has agreed to offer to resign as a director. In addition, pursuant to the Agreement, the Filing Parties agreed to certain standstill provisions that restrict them from, among other things, (i) commencing any tender offer or exchange offer for any of the Company's securities, (ii) submitting or encouraging any other person or group to submit nominations for director for election to the Company's Board of Directors, (iii) submitting any stockholder proposals, (iv) calling an annual or special meeting of stockholders, or (v) soliciting proxies from stockholders of the Company. The Agreement, however, does not restrict the Filing Parties from (a) nominating one or more persons for election as director at any annual meeting after the Company's 2008 annual meeting or (b) soliciting proxies or consents with respect to Company voting stock (including taking actions in support or furtherance of any such solicitation including to cause cumulative voting to be in effect) (i) in favor of or in opposition to the election of any persons so nominated for election to the Board of Directors at any annual meeting after the Company's 2008 annual meeting or (ii) in regard to any other matter that may be brought before the Company's stockholders by the Company or any other stockholder at any annual meeting after the Company's 2008 annual meeting. Depending upon OPP's view of the Company's business and financial prospects and general market conditions, the Partnerships may purchase additional Shares or dispose of Shares at any time or from time to time. Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer. ----------------------------------------- Item 6 is hereby amended by deleting Item 6 in its entirety and by substituting the following in lieu thereof: As described in Item 4 above, on January 31, 2008 the Filing Parties entered into the Agreement. In addition to the terms of the Agreement described in Item 4 above, the Agreement provides that, during the effective period of certain restrictions set forth therein, the Filing Parties will cause any Shares held by the Partnerships to be voted in accordance with the recommendation of the Company's Board of Directors if Mr. Press has approved and joined in any such recommendation. The descriptions of the Agreement set forth in this Schedule 13D, as amended, are qualified in their entirety by reference to the complete agreement governing such matters, which is incorporated by reference to this Schedule 13D Amendment No. 3 as an exhibit pursuant to Item 7 hereof. Except as otherwise described herein, no contracts, arrangements, understandings or similar relationships exist with respect to the securities of the Company between the Filing Parties or the Partnerships and any person or entity.
