Dealing Disclosure Requirements

Under the provisions of Rule 8.3 of the Code, if any person is, or becomes, "interested" (directly or indirectly) in 1 per cent. or more of any class of "relevant securities" of SPI Lasers, all "dealings" in any "relevant securities" of SPI Lasers (including by means of an option in respect of, or a derivative referenced to, any such "relevant securities") must be publicly disclosed by no later than 3.30 p.m. (London time) on the Business Day following the date of the relevant transaction. This requirement will continue until the date on which the Offer becomes, or is declared, unconditional as to acceptances, lapses or is otherwise withdrawn or on which the "offer period" otherwise ends. If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire an "interest" in "relevant securities" of SPI Lasers, they will be deemed to be a single person for the purpose of Rule 8.3.

Under the provisions of Rule 8.1 of the Code, all "dealings" in "relevant securities" of SPI Lasers by TRUMPF, TRUMPF International or SPI Lasers, or by any of their respective "associates", must be disclosed by no later than 12.00 noon (London time) on the Business Day following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose "relevant securities" "dealings" should be disclosed, and the number of such securities in issue, can be found on the Panel's website at www.thetakeoverpanel.org.uk.

"Interests in securities" arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities. In particular, a person will be treated as having an "interest" by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.

Terms in quotation marks above are defined in the Code, which can also be found on the Panel's website. If you are in any doubt as to whether or not you are required to disclose a "dealing" under Rule 8 of the Code, you should consult the Panel.

If you are in any doubt as to the application of Rule 8 to you, please contact an independent financial adviser authorised under the Financial Services and Markets Act 2000, consult the Panel's website at www.thetakeoverpanel.org.uk or contact the Panel on telephone number +44 (0) 20 7638 0129; fax +44 (0) 20 7236 7013.
