The Company represents to and agrees with each Investor that it will not give any instruction to the Transfer Agent that will conflict with the foregoing Instruction.

          (e) To the Company’s knowledge, all licenses or other agreements under which the Company or any of its Subsidiaries has granted rights to Intellectual Property to others (including all end-user agreements) since January 1, 2005, are in full force and effect, there has been no material default by the Company or any of its Subsidiaries thereunder and there is no material default by any other party thereto.

The Company represents to and agrees with each Investor that it will not give any instruction to the Transfer Agent that will conflict with the foregoing instruction or otherwise restrict such Investor’s right to exercise the Warrant or to receive the Warrant Shares upon exercise of the Warrant.

The Company will not be liable to any Investor Party under this Agreement (i) for any settlement by an Investor Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (ii) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to such Investor Party’s wrongful actions or omissions, or gross negligence or to such Investor Party’s breach of any of the representations, warranties, covenants or agreements made by such Investor in this Agreement or in the other Transaction Documents.

3.7 No Conflicts

None

3.8 Financial Condition: Taxes; Litigation

     3.8.1 None

     3.8.4 Litigation:

     On June 26, 2001, a putative securities class action captioned Lanter v. New Focus, Inc. et al., Civil Action No. 01-CV-5822, was filed against New Focus, Inc. and several of its officers and directors, or the Individual Defendants, in the United States District Court for the Southern District of New York. Also named as defendants were Credit Suisse First Boston Corporation, Chase Securities, Inc., U.S. Bancorp Piper Jaffray, Inc. and CIBC World Markets Corp., or the Underwriter Defendants, the underwriters in New Focus’s initial public offering. Three subsequent lawsuits were filed containing substantially similar allegations. These complaints have been consolidated. On April 19, 2002, plaintiffs filed an Amended Class Action Complaint, described below, naming as defendants the Individual Defendants and the Underwriter Defendants.

On November 7, 2001, a Class Action Complaint was filed against Bookham Technology plc and others in the United States District Court for the Southern District of New York. On April 19, 2002, plaintiffs filed an Amended Complaint. The Amended Complaint names as defendants Bookham Technology plc, Goldman, Sachs & Co. and FleetBoston Robertson Stephens, Inc., two of the underwriters of Bookham Technology plc’s initial public offering in April 2000, and Andrew G. Rickman, Stephen J. Cockrell and David Simpson, each of whom was an officer and/or director at the time of the initial public offering.

The Amended Complaint asserts claims under certain provisions of the securities laws of the United States. It alleges, among other things, that the prospectuses for Bookham Technology plc’s and New Focus’s initial public offerings were materially false and misleading in describing the compensation to be earned by the underwriters in connection with the offerings, and in not disclosing certain alleged arrangements among the underwriters and initial purchasers of ordinary shares, in the case of Bookham Technology plc, or common stock, in the case of New Focus, from the underwriters. The Amended Complaint seeks unspecified damages (or in the alternative rescission for those class members who no longer hold ordinary shares, in the case of Bookham Technology plc or common stock, in the case of New Focus), costs, attorneys’ fees, experts’ fees, interest and other expenses. In October 2002, the individual defendants were dismissed, without prejudice,from the action. In July 2002, all defendants filed Motions to Dismiss the Amended Complaint. The motion was denied as to Bookham Technology plc and New Focus in February 2003. Special committees of the board of directors authorized the companies to negotiate a settlement of pending claims substantially consistent with a memorandum of understanding negotiated among class plaintiffs, all issuer defendants and their insurers.

Plaintiffs and most of the issuer defendants and their insurers have entered into a stipulation of settlement for the claims against the issuer defendants, including the Company. Under the stipulation of settlement, the plaintiff will dismiss and release all claims against participating defendants in exchange for a payment guaranty by the insurance companies collectively responsible for insuring the issuers in the related cases, and the assignment or surrender to the

plaintiffs of certain claims the issuer defendants may have against the underwriters. On February 15, 2005, the Court issued an Opinion and Order preliminarily approving the settlement provided that the defendants and plaintiffs agree to a modification narrowing the scope of the bar order set forth in the original settlement agreement. The parties agreed to the modification narrowing the scope of the bar order, and on August 31, 2005, the court issued an order preliminarily approving the settlement and setting a public hearing on its fairness for April 24, 2006. The Company believes that both Bookham Technology, plc and New Focus have meritorious defenses to the claims made in the Amended Complaint and therefore believes that such claims will not have a material effect on its financial position, results of operations or cash flows.

On February 13, 2002, Howard Yue, the former sole shareholder of Globe Y. Technology, Inc., a company acquired by New Focus in February 2001, filed a lawsuit against New Focus and several of its officers and directors in Santa Clara County Superior Court. The lawsuit is captioned Howard Yue v. New Focus, Inc. et al, Case No. CV808031, and asserts claims stemming from New Focus’s acquisition of Globe Y. Technology, Inc. The plaintiff has amended his complaint several times following the Court’s dismissal of his earlier complaints. Currently, the plaintiff’s fifth amended complaint alleges the following causes of action against New Focus: violation of §25400 and §25500 of the California Corporations Code; violation of §§1709-1710 of the California Civil Code; violation of §25402 of the California Corporations Code; violation of §17200 and §17500 of the California Business & Professions Code; fraud and deceit by concealment; fraud and deceit by active concealment; fraud and deceit based upon non-disclosure of material facts; negligent misrepresentation; and breach of contract and the duty of good faith and fair dealing. The complaint seeks unspecified economic, punitive, and exemplary damages, prejudgment interest, costs, and equitable and general relief. In November 2004 New Focus filed answers to the plaintiff’s fifth amended complaint denying the plaintiff’s allegations and asserting various defenses. The trial date had been set for March 13, 2006. The Company intends to conduct a vigorous defense of this lawsuit.
