Item 3. Source and Amount of Funds or Other Consideration. As described in the response to Item 4, each of the Stockholder Parties has entered into Voting Undertakings in connection with the execution and delivery by Nortel Networks of the Acquisition Agreement (as defined below). Nortel Networks' willingness to enter into the Acquisition Agreement was subject to, among other things, the execution and delivery of the Voting Undertakings. Item 4. Purpose of Transaction. Acquisition Agreement Nortel Networks and Bookham entered into an Acquisition Agreement, dated as of October 7, 2002 (the "Acquisition Agreement"), a copy of which is filed herewith as Exhibit 1 and incorporated by reference herein. Pursuant to the Acquisition Agreement, Nortel Networks agreed to sell certain assets comprising a part of Nortel Networks' optical components business to Bookham and, in consideration thereof, among other things, Bookham will issue to Nortel Networks 61,000,000 Ordinary Shares of Bookham and 9,000,000 warrants to acquire Ordinary Shares at an exercise price of one third pence each (the "Warrants"). The Acquisition Agreement provides that the number of Ordinary Shares and Warrants to be issued to Nortel Networks upon the closing of the transactions contemplated by the Acquisition Agreement shall be subject to adjustment in the event of a consolidation, subdivision or reorganization, stock dividend, distribution or issuance of any rights to acquire equity securities of Bookham or any similar transaction with respect to the Ordinary Shares of Bookham prior to the issuance of such Ordinary Shares and Warrants to Nortel Networks. Consummation of the transactions contemplated by the Acquisition Agreement is subject to the satisfaction or waiver of certain conditions, including, but not limited to, approval of the Acquisition Agreement and certain related matters by a majority of the holders of the outstanding Ordinary Shares of Bookham, expiration or termination of any waiting period under applicable law relating to competition or antitrust, delivery of executed versions of all agreements contemplated by the Acquisition Agreement and other customary conditions. The Acquisition Agreement contains certain customary restrictions on the conduct of the business of Bookham pending the consummation of the transactions contemplated by the Acquisition Agreement, including, without limitation, with respect to the declaration or payment of any dividend or distribution on any shares of its capital stock. The Acquisition Agreement provides that, at the closing of the transactions contemplated thereby, Nortel Networks and Bookham will enter into a relationship deed (the "Relationship Deed") pursuant to which Nortel Networks will undertake, among other things that for as long as Nortel Networks or any of its affiliates, individually or collectively, own five per cent or more of the issued Ordinary Shares, (i) Nortel Networks will abstain, and will ensure that its affiliates abstain, from exercising its (or their) right to vote any of the Ordinary Shares it (or they) own (except in the case of any proposed resolution the effect of which would, if passed, be to vary or suspend any of the rights attaching to such Ordinary Shares or as a result of which the rights of Nortel Networks and its affiliates, in their capacity as Bookham shareholders, would become different in any respect from the rights of any other Bookham Shareholder), and (ii) Nortel Networks will ensure that all transactions, agreements or arrangements entered into between Nortel Networks or its affiliates and Bookham are at arm's length and on a normal commercial basis. The obligations under the Relationship Deed will not apply to any transferees of Ordinary Shares held by Nortel Networks and its affiliates unless the transferees are also affiliates of Nortel Networks. The Acquisition Agreement also provides that Bookham and Nortel Networks Limited, a subsidiary of Nortel Networks ("Nortel Networks Limited"), will enter into a supply agreement pursuant to which Nortel Networks Limited will be required to purchase from Bookham a minimum of $120,000,000 of optical components products and related services over a period of six quarters following the closing. In addition, over the three years following the closing, Nortel Networks Limited has agreed to purchase from Bookham agreed percentages on a product-by-product basis of its total requirements for optical components products, subject to Bookham's meeting certain customary performance criteria including as to quality and delivery. Voting Undertakings As a further condition and inducement to Nortel Networks' entering into the Acquisition Agreement, concurrently with the execution of the Acquisition Agreement, the Stockholder Parties entered into Voting Undertakings, copies of which are filed herewith as Exhibits 2, 3, 4, 5 and 6 and incorporated herein by reference. Pursuant to the Voting Undertakings, the Stockholder Parties have agreed to vote in favor of the adoption of the resolutions relating to the Acquisition Agreement and the transactions contemplated thereby (i) the 42,387,878 Ordinary Shares of Bookham over which they, collectively, have voting power and (ii) except in the case of Marconi, any of the Ordinary Shares of Bookham that they may acquire, including upon the exercise of stock options that are currently exercisable or that will become exercisable in the next 60 days, which Ordinary Shares of Bookham such Stockholder Parties are deemed to beneficially own pursuant to Exchange Act Rule 13d-3(d)(1)(i). Each of the Stockholder Parties other than Marconi has irrevocably appointed the directors of Bookham to act as such Stockholder Party's attorney-in-fact for the purpose of voting such shares. In addition, the Stockholder Parties other than Marconi have agreed not to dispose of any Ordinary Shares of Bookham that they hold or acquire until the date of the extraordinary general meeting of Bookham. The foregoing summaries of the Acquisition Agreement and Voting Undertakings do not purport to be complete and are qualified in their entirety by reference to the text of the Acquisition Agreement and the Voting Undertakings incorporated by reference as Exhibits 1, 2, 3, 4, 5 and 6 hereto. Except as set forth in the Acquisition Agreement, the Voting Undertakings or this Statement, neither Nortel Networks nor, to the best of Nortel Networks' knowledge, any of the individuals named in Schedule I hereto has any plans or proposals which relate to or which would result in any of the actions specified in subparagraphs (a) through (j) of Item 4 of Schedule 13D. Item 5. Interest in Securities of the Issuer. (a) - (b) Nortel Networks may, as a result of the Voting Undertakings, be deemed to beneficially own the Ordinary Shares of Bookham that are held, collectively, by the Stockholder Parties and, pursuant to Exchange Act Rule 13d-3(d)(1)(i), the Ordinary Shares of Bookham that are subject to stock options held by the Stockholder Parties other than Marconi (and which are exercisable currently or within the next 60 days, together, the "Beneficially Owned Ordinary Shares"). As of the date hereof, the aggregate number of Beneficially Owned Ordinary Shares is 44,266,454, representing approximately 30.4% of the outstanding Ordinary Shares (assuming 143,851,805 Ordinary Shares of Bookham outstanding on October 7, 2002, as represented to Nortel Networks by Bookham in the Acquisition Agreement, plus 1,878,576 Ordinary Shares of Bookham subject to stock options held, collectively, by the Stockholder Parties other than Marconi that are currently exerciseable or that will become exerciseable in the next 60 days). The Stockholder Parties and Nortel Networks may be deemed to have shared power to vote or to direct the vote with respect to the Beneficially Owned Ordinary Shares. The Voting Undertakings also provide that the Stockholder Parties other than Marconi may not dispose of any Beneficially Owned Ordinary Shares, and thus Nortel Networks may be deemed to have shared power to dispose or direct the disposition of the Beneficially Owned Ordinary Shares. Except as set forth in this Item 5, none of Nortel Networks or, to the best of Nortel Networks' knowledge, any of the individuals named in Schedule I hereto beneficially owns any Ordinary Shares of Bookham. (c) Except for entering into the agreements described above, neither Nortel Networks nor, to the best of Nortel Networks' knowledge, any of the individuals named in Schedule I hereto has effected any transaction in Ordinary Shares of Bookham during the past 60 days. (d) Nortel Networks does not have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any Ordinary Shares of Bookham. (e) Not applicable. Item 6. Contracts, Arrangements, Understanding or Relationships with Respect to Securities of Bookham. Except as provided in this Statement, neither Nortel Networks nor, to the best of Nortel Networks' knowledge, any of the individuals named in Schedule I hereto has any contracts, arrangements, understandings or relationships (legal or otherwise) with any person with respect to any securities of Bookham, including, but not limited to, transfer or voting of any of the 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.
