(b) pay or discharge before becoming delinquent (a) all taxes, levies, assessments and governmental charges imposed on it or its income or profits or any of its Property and (b) all lawful claims for labor, material and supplies, which, if unpaid, might become a Lien (other than a Permitted Lien) upon any of its Property, except where the failure to do so would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect; provided, however, that the Company shall not be required to pay or discharge any tax, levy, assessment or governmental charge, or claim for labor, material or supplies, whose amount, applicability or validity is being contested in good faith by appropriate proceedings being diligently pursued and for which adequate reserves have been established under US GAAP;

(g) timely file with the Commission all reports required to be filed pursuant to the Exchange Act and refrain from terminating its status as an issuer required by the Exchange Act to file reports thereunder even if the Exchange Act or the rules or regulations thereunder would permit such termination (other than a termination resulting from a Change of Control (as defined in the Debentures));

4.3 Reservation of Common Stock. The Company shall, on each Closing Date, have authorized and reserved for issuance to the Investors free from any preemptive rights, and shall keep available at all times during which any or Warrants are outstanding, a number of shares of Common Stock (the "Reserved Amount") that, on such Closing Date, is not less than one hundred percent (100%) of the sum of (A) the number of Conversion Shares issuable upon conversion of all of the Debentures issued or issuable at or prior to such Closing plus (B) the number of Warrant Shares issuable upon exercise of all of the Warrants issued or issuable at or prior to such Closing, in each case without regard to any limitation or restriction on such conversion or exercise that may be set forth in the Debentures or the Warrants. The Reserved Amount shall be allocated in accordance with each Investor's Pro Rata Share. In the event that an Investor shall sell or otherwise transfer any of such Investor's Debentures or Warrants, each transferee shall be allocated a pro rata portion of such transferor's Reserved Amount. Any portion of the Reserved Amount allocated to any Investor or other Person which no longer holds any Debentures or Warrants shall be reallocated to the remaining Investors pro rata based on the number of Registrable Securities held by such Investors at such time.

hundred percent (100%) of the Registrable Securities issuable upon such conversion and exercise), such increase to be effective not later than the thirtieth (30th) day (or sixtieth (60th) day, in the event stockholder approval is required for such increase) following the Company's receipt of written notice of such deficiency.

(a) the Company may make payments of principal and interest accrued on any Permitted Debt other than Subordinated Debt, on which the Company may only make regularly scheduled payments of interest; and

(b) Subsidiaries of the Company may make Restricted Payments to the Company;

provided, however, that no Restricted Payments may be made pursuant to clause (a) or (b) above if an Event of Default (or an event or circumstance that with the giving of notice or lapse of time would constitute an Event of Default) exists at the time of such Restricted Payment or would result therefrom.

4.7 Acquisitions and Investments. During the period beginning on the Execution Date and ending on the date that is six (6) months following the Effective Date, the Company will not, nor will it permit any Subsidiary of the Company to, purchase or otherwise acquire the capital stock or other equity interests in or assets (constituting a business unit) of, any Person (or agree to do so, unless the business or entity so acquired has, as of immediately following such acquisition, cash and cash equivalents (that are acquired with such business or entity) that exceed the amount of the total indebtedness of such business or entity. In addition, the Company and/or its Subsidiaries may acquire businesses or entities with an aggregate enterprise value for all such acquired businesses and entities of not more than $10,000,000 (i.e. purchase price plus the excess of assumed liabilities over cash and cash equivalents) that do not satisfy such criteria.

4.9 Right of Participation.

(a) Offered Securities. From the Effective Date through the Termination Date, the Company will not, directly or indirectly, effect a Subsequent Placement, unless in each such case the Company shall have first offered to sell to the Investors at least fifty percent (50%) of the securities being offered in such Subsequent Placement (the securities being offered to the Investors being referred to herein as the "Offered Securities"). The Company shall offer to sell to each Investor (A) such Investor's Pro Rata Share of the Offered Securities (the "Basic Amount"), and (B) such additional portion of the Offered Securities as such Investor shall indicate it will purchase should the other Investors subscribe for less than their Basic Amounts (the "Undersubscription Amount"), at a price and on such other terms as shall have been specified by the Company in writing delivered to such Investor (the "Offer"), which Offer by its terms shall remain open and irrevocable for a period of not less than ten (10) Business Days from such Investor's receipt of the terms of the Offer in writing (the "Offer Period").

(b) Notice of Acceptance. Each Investor that wishes to accept the Offer shall deliver written notice thereof (a "Notice of Acceptance") to the Company prior to the expiration of the Offer Period, specifying the amount of such Investor's Basic Amount that the Investor elects to purchase and, if such Investor elects to purchase all of its Basic Amount, the Undersubscription Amount that Investor elects to purchase. If the aggregate of the Basic Amounts subscribed for by all

Investors is less than the total Offered Securities, each Investor who has indicated in its Notice of Acceptance that it wishes to purchase Undersubscription Amounts shall be entitled to purchase all Undersubscription Amounts it has subscribed for; provided, however, that if the aggregate of the Undersubscription Amounts subscribed for exceed the difference between the Offered Securities and the Basic Amounts subscribed for (the "Available Undersubscription Amount"), each Investor who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Undersubscription Amount subscribed for by such Investor bears to the total Undersubscription Amounts subscribed for by all Investors, subject to rounding by the Board of Directors to the extent it deems reasonably necessary.

(c) Permitted Sales Of Refused Securities. In the event that Notices of Acceptance are not timely delivered by the Investors in respect of all the Offered Securities, the Company shall have forty-five (45) days from the expiration of the Offer Period to close the sale of all or any part of such Offered Securities as to which a Notice of Acceptance has not been given by an Investor (the "Refused Securities") to the Person or Persons specified in the Offer, but only upon terms and conditions, including, without limitation, unit price and interest rates (if applicable), which are, in the aggregate, no more favorable to such other Person or Persons or less favorable to the Company than those set forth in the Offer.

(d) Reduction in Amount of Offered Securities. In the event that the Company proposes to sell less than all the Refused Securities (any such sale to be in the manner and on the terms specified in paragraph (c) above), then each Investor may, at its option and in its sole and absolute discretion, reduce the number or other units of the Offered Securities specified in its Notice of Acceptance to an amount which shall be not less than the amount of the Offered Securities which such Investor elected to purchase pursuant to paragraph (b) above multiplied by a fraction, (A) the numerator of which shall be the amount of Offered Securities which the Company actually proposes to sell, and (B) the denominator of which shall be the amount of all Offered Securities. In the event that any Investor so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not sell or otherwise dispose of more than the reduced amount of the Offered Securities until such securities have been offered to the Investors in accordance herewith.

(e) Closing. Upon each closing of the purchase and sale of Offer Securities, the Investor shall purchase from the Company, and the Company shall sell to the Investor the number of Offered Securities specified in the Notices of Acceptance, as reduced pursuant to paragraph (d) above if the Investors have so elected, upon the terms and conditions specified in the Offer. The purchase by the Investors of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and the Investors of a purchase agreement relating to such Offered Securities on the same terms and conditions applicable to other Persons purchasing the Offered Securities.

(f) Further Sale. In each case, any Offered Securities not purchased by the Investors or other Person or Persons in accordance herewith may not be sold or otherwise disposed of by the Company until they are again offered to the Investors under the procedures specified herein.

4.10 Certain Transactions. During the period beginning on the Execution Date and ending on the date that is six (6) months following the Effective Date, and except as may be expressly permitted or required by the Transaction Documents, the Company will not, nor will it permit any Subsidiary of the Company to, create or otherwise cause or permit to exist or become effective any consensual encumbrance or restriction of any kind on the ability of the Company or any Subsidiary of the Company to (a) pay dividends or make any other distribution to the Company or any Subsidiary of the Company in respect of capital stock or with respect to any other interest or participation in, or

measured by, its profits, or (b) pay any amounts that are or become payable under any of the Transaction Documents.

4.11 Transactions with Affiliates. The Company agrees that any transaction or arrangement between it or any of its Subsidiaries and any Affiliate or employee of the Company shall be effected on an arms' length basis and shall be approved by the Board of Directors, including a majority of the Company's directors not having an interest in such transaction.

4.12 Use of Investor Name. Except as may be required by applicable law and/or this Agreement, the Company shall not use, directly or indirectly, any Investor's name or knowingly use the name of any of its Affiliates in any advertisement, announcement, press release or other similar communication unless it has received the prior written consent of such Investor or its Affiliate, as the case may be, for the specific use contemplated or as otherwise required by applicable law or regulation.

4.13 Company's Instructions to Transfer Agent. On or prior to the Closing Date, the Company shall execute and deliver irrevocable written instructions to the transfer agent for its Common Stock (the "Transfer Agent"), and provide each Investor with a copy thereof, directing the Transfer Agent (i) to issue certificates representing Conversion Shares upon conversion of the Debentures and receipt of a valid Conversion Notice (as defined in the Debentures) from an Investor, in the amount specified in such Conversion Notice, in the name of such Investor or its nominee, (ii) to issue certificates representing Warrant Shares upon exercise of the Warrants and (iii) to deliver such certificates to such Investor no later than the close of business on the third (3rd) business day following the related Conversion Date (as defined in the Debentures) or Exercise Date (as defined in the Warrant), as the case may be. Such certificates may bear legends pursuant to applicable provisions of this Agreement or applicable law. The Company shall instruct the transfer agent that, in lieu of delivering physical certificates representing shares of Common Stock to an Investor upon conversion of the Debentures, or exercise of the Warrants, and as long as the Transfer Agent is a participant in the Depository Trust Company ("DTC") Fast Automated Securities Transfer program, and such Investor has not informed the Company that it wishes to receive physical certificates therefor, and no restrictive legend is required to appear on any physical certificate if issued, the transfer agent may effect delivery of Conversion Shares or Warrant Shares, as the case may be, by crediting the account of such Investor or its nominee at DTC for the number of shares for which delivery is required hereunder within the time frame specified above for delivery of certificates. 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 convert the Debentures or to receive Conversion Shares in accordance with the terms of the Debentures or to exercise the Warrant or to receive Warrant Shares upon exercise of the Warrants. In the event that the Company's relationship with the Transfer Agent should be terminated for any reason, the Company shall use its best efforts to cause the Transfer Agent to continue acting as transfer agent pursuant to the terms hereof until such time that a successor transfer agent is appointed by the Company and receives the instructions described above.

4.14 Limitations on Disposition. No Investor shall sell, transfer, assign or dispose of any Securities, unless:

(a) there is then in effect an effective registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or

(b) such Investor has notified the Company in writing of any such disposition, has received the Company's written consent (which consent will not be unreasonably withheld) to such disposition and furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such Securities under the Securities Act; provided, however, that no such consent or opinion of counsel will be required (A) if the sale, transfer or assignment is made to an Affiliate of such Investor in compliance with applicable

securities laws, (B) if the sale, transfer or assignment is made pursuant to Rule 144 and such Investor provides the Company with customary representations and/or other evidence reasonably satisfactory to the Company that the proposed transaction satisfies the requirements of Rule 144, or (C) in connection with a bona fide pledge or hypothecation of any Securities under a margin arrangement with a broker-dealer or other financial institution or the sale of any such Securities by such broker-dealer or other financial institution following such Investor's default under such margin arrangement.

4.15 Disclosure of Information. The Company agrees that it will not at any time following the Execution Date disclose material non-public information to any Investor without first obtaining such Investor's written consent to such disclosure.

4.16 Listing. The Company (i) has, or promptly following the Closing shall, use its best efforts to include all of the Conversion Shares issuable upon conversion of the Debentures and all of the Warrant Shares issuable upon exercise of the Warrants (without regard to any limitation on such conversion or exercise) for listing on the Nasdaq National Market, and (ii) shall use its best efforts to maintain the designation and quotation, or listing, of the Common Stock on the Nasdaq National Market or the New York Stock Exchange for a minimum of five (5) years following the Closing Date (other than any termination of such designation and quotation or listing that results from a Change of Control).

4.17 Indemnification of Investors. The Company will indemnify and hold each Investor and its directors, managers, officers, shareholders, members, partners, employees and agents (each, an "Investor Party") harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys' fees and costs of investigation that any such Investor Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents or (b) any action instituted against an Investor, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate of such Investor, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is based upon a breach of such Investor's representation, warranties or covenants under the Transaction Documents or any agreements or understandings such Investor may have with any such stockholder or any violations by such Investor of state or federal securities laws or any conduct by such Investor which constitutes fraud, gross negligence, willful misconduct or malfeasance). If any action shall be brought against any Investor Party in respect of which indemnity may be sought pursuant to this Agreement, such Investor Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing. Any Investor Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Investor Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time following such Investor Party's written request that it do so, to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion of such separate counsel, a material conflict on any material issue between the position of the Company and the position of such Investor Party. 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.

4.18 Indemnification of the Company. Each Investor, severally and not jointly, will indemnify and hold the Company and its directors, managers, officers, shareholders, members, partners, employees and agents (each, a "Company Party") harmless from any and all losses, liabilities, obligations, claims,

contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys' fees and costs of investigation that any such Company Party may suffer or incur as a result of or relating to any breach of any of the representations, warranties, covenants or agreements made by such Investor in this Agreement or in the other Transaction Documents. If any action shall be brought against any Company Party in respect of which indemnity may be sought from an Investor pursuant to this Agreement, such Company Party shall promptly notify such Investor in writing, and such Investor shall have the right to assume the defense thereof with counsel of its own choosing. Any Company Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Company Party except to the extent that (i) the employment thereof has been specifically authorized by the indemnifying Investor in writing, (ii) such Investor has failed after a reasonable period of time following such Company Party's written request that it do so, to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion of such separate counsel, a material conflict on any material issue between the position of the Company Party and the position of such Investor. No Investor will be liable to any Company Party under this Agreement (i) for any settlement by a Company Party effected without such Investor'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 Company Party's wrongful actions or omissions, or gross negligence or to the Company's breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents.

3.8 Financial Condition: Taxes; Litigation

3.8.1: None
3.8.4: Litigation:

On June 26, 2001, a putative securities class action captioned Xxxxxx v. New Focus, Inc. et al., Civil Action No. 01-CV-5822, was filed against New Focus 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 Xxxxx Xxxxxxx, 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, the plaintiffs filed an Amended Class Action Complaint. The Amended Complaint names as defendants Bookham Technology plc, Xxxxxxx, Sachs & Co. and FleetBoston Xxxxxxxxx Xxxxxxxx, Inc., two of the underwriters of Bookham Technology plc's initial public offering in April 2000, and Xxxxxx X. Xxxxxxx, Xxxxxxx X. Xxxxxxxx and Xxxxx Xxxxxxx, each of whom was an officer and/or director at the time of the initial public offering.

The Amended Complaints assert claims under certain provisions of the securities laws of the United States. They allege, 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 Complaints seek 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 the pending claims substantially consistent with a memorandum of understanding negotiated among class plaintiffs, all issuer defendants and their insurers. A stipulation of settlement for the claims against the issuer defendants has been submitted to the court for preliminary approval. Under the stipulation of settlement, the plaintiffs will dismiss and release all claims against participating defendants in exchange for a contingent payment guaranty by the insurance companies collectively responsible for insuring the issuers in all the related cases, and the assignment or surrender to the plaintiffs of certain claims the issuer defendants may have against the underwriters. Under the guaranty, the insurers will be required to pay the amount, if any, by which $1.0 billion exceeds the aggregate amount ultimately collected by the plaintiffs from the underwriter defendants in all the cases. There is no guarantee that the settlement will become effective, as it is subject to a number of conditions, including court approval.

On February 13, 2002, Xxxxxx Xxx, 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 Xxxxx County Superior Court. The lawsuit is captioned Xxxxxx Xxx v. New Focus, Inc. et al, Xxxx Xx. XX000000, and asserts claims stemming from New Focus's acquisition of Globe Y. 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 § 25402 of the California Corporations Code; violation of §§1709-1710 of the California Civil 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. New Focus recently filed an answer to plaintiff's fifth amended complaint denying plaintiff's allegations and asserting various defenses.

In addition, in October 2003, New Focus filed a cross-complaint against Xx. Xxx seeking damages in connection with Xx. Xxx'x conduct during the acquisition of Globe Y by New Focus. In February 2004, New Focus filed a corrected amended cross-complain against Xx. Xxx. In May 2004, Xx. Xxx filed an answer to New Focus's corrected amended cross-complaint denying New Focus's allegations and asserting various defenses. A trial date has been set for March 21, 2005.

On or about January 30, 2004, a lawsuit was filed in the United States District Court for the Eastern District of Virginia against Bookham Technology plc, certain individuals affiliated with Bookham Technology plc, Xxxxxxx Xxxxx, Xxxxxxx Xxxxx International, Xxxxxxxxx Xxxxxxxx, Xxxxxxxxx Xxxxxxxx International, Xxxxxx Xxxx & Company Ltd., Dexia PrivatBank Switzerland, Swiss Partners Investment Network Ltd., or Spin, and certain individuals affiliated with Spin. The complaint is captioned Xxxxxxx v. Bookham Technology PLC, et al., Case No. 1:04-CV-00054. The suit purports to allege that defendants violated the federal securities laws in connection with

Bookham Technology plc's initial public offering conducted on or about April 11, 2000, Bookham Technology plc's follow-on public offering conducted on or about September 19, 2000, and the trading of Bookham Technology plc's shares in the aftermarket from the date of the initial public offering through December 6, 2000. The complaint purports to allege violations of Sections 3(a)(8), 5, 11 and 15 of the Securities Act of 1933, as amended, Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Section 203 of the Investment Advisers Act of 1940, as amended. It purports to incorporate allegations made by plaintiffs in the IPO laddering litigation described above. The suit purports to seek damages in the sum of at least $25 million, fees and costs. On May 20, 2004, the plaintiff filed a motion seeking to extend the deadline for service of the complaint until September 17, 2004. The court granted plaintiff's motion on May 21, 2004. The plaintiff never served the complaint and on September 30, 2004, the court dismissed the case without prejudice.
