4. Share Capital

The Company will not, without the prior written consent of Nortel, reduce its ordinary share capital in any way or redeem or purchase any of its Ordinary Shares if, as a result of such reduction, redemption or purchase, Nortel or the Shareholders would be obliged under the City Code on Takeovers and Mergers to make an offer to acquire any shares it does not already own in the Company and, if there is any ambiguity as to whether any such reduction, redemption or purchase would trigger such an obligation, the Company shall (prior to effecting such reduction, redemption or purchase) consult with Nortel and the Panel and both parties shall abide by any determination made by the Panel.

5. Assignment

No party shall assign or in any other way dispose of any of its rights or obligations under this Deed without the prior written consent of the other party.

6. Change of law

If there is any change in law or applicable regulations which would materially affect the operation of this Deed, the parties hereto agree to enter into bona fide negotiations with a view to agreeing such amendments to this Deed as the parties shall in good faith determine to be necessary to ensure that notwithstanding such changes the intentions of each as reflected by the provisions of this Deed are given effect.

7. Duration

This Deed shall continue in full force and effect for so long as Nortel or any Shareholder Group Member or any associate of Nortel, individually or collectively, remain a Bookham Shareholder holding 5% or more of the issued ordinary share capital of the Company from time to time. If as a result of any future issue, sale or disposal of Ordinary Shares, Nortel and Shareholder Group Members collectively cease to hold 5% or more of the issued ordinary share capital of the Company from time to time, then this Deed shall terminate and cease to be of any effect other than clauses, 5 (Assignment), 7 (Duration), 9 (Severance), 10 (Entire Agreement), 11 (General), 12 (Notices), 13 (Governing Law) save that this shall not relieve any party from any liability or obligation in respect of any matters, undertakings or conditions which shall not have been done, observed or performed by that party whilst this Deed is in effect.

8. Deed of Adherence

8.1: Except with the written consent of the Company, if any of the Shareholder Group Members party hereto make a Disposal to or in favour of any other Shareholder Group Member that is not a party hereto over any of the Ordinary Shares (in each case, a "New Shareholder"), prior to such Disposal such disposing party shall procure that such New Shareholder enter into a Deed of Adherence in the form set out in the Schedule.
8.2: If any Shareholder Group Member makes a Disposal to any person that is not a Shareholder Group Member, the restrictions set forth in this Deed shall not apply to such transferee.

9. Severance

9.1: If any provision of this Deed is held to be invalid or unenforceable, then such provision shall (so far as it is invalid or unenforceable) be given no effect and shall be deemed not to be included in this Deed but without invalidating any of the remaining provisions of this Deed. In such event, the parties shall co-operate and negotiate in good faith to agree provisions (to replace those which are invalid or unenforceable) which are not invalid or unenforceable, or which can otherwise be put into effect and which, as far as possible, are legally and commercially the same as those they replace.
9.2: In the event that provisions of this Deed need to be interpreted or supplemented then the interpretation or supplement shall be completed in good faith in such a way that the spirit, contents and purpose of this Deed are adhered to as far as possible.

10. Entire Agreement

10.1: It is hereby acknowledged that this Deed constitutes the entire agreement between the parties and supersedes all prior agreements, understandings or arrangements (both oral and written) relating to the subject matter of this Deed.
10.2: No amendment, change or addition to this Deed shall be effective or binding on any party unless reduced to writing and executed as a deed by both parties.

11. General

11.2: This Deed shall not be construed as creating any partnership or agency (except to the extent expressly described) relationship between any of the parties.
11.3: No relaxation, forbearance, indulgence or delay (together "indulgence") of any party in exercising any right shall be construed as a waiver of the right and shall not affect the ability of that party subsequently to exercise that right or to pursue any remedy, nor shall any indulgence constitute a waiver of any other right.
11.4: A person who is not a party to this Deed may not enforce any of its terms under the Contracts (Rights of Third Parties) ▇▇▇ ▇▇▇▇, provided that no consent of a person who is not a party to this Deed is required for any variation (including any release or compromise in whole or in part of any liability) or termination of this Deed.

13. Governing law and jurisdiction

13.1: This Deed shall be governed by and construed in accordance with English law.
13.2: The courts of England shall have exclusive jurisdiction to settle any claim, dispute or matter of difference which may arise out of or in connection with this Deed (including without limitation claims for set-off or counterclaim) or the legal relationships established by this Deed.
