AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”), dated as of September 21, 2003, is entered into by and among Bookham Technology plc, a public limited company incorporated under the laws of England and Wales (the “Parent”), Budapest Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of the Parent (the “Transitory Subsidiary”), and New Focus, Inc., a Delaware corporation (the “Company”).

WHEREAS, the Boards of Directors of the Parent and the Company deem it advisable and in the best interests of each corporation and their respective stockholders that the Parent combine with the Company in order to advance the long-term business interests of the Parent and the Company;

WHEREAS, the business combination of the Company shall be effected through a merger (the “Merger”) of the Transitory Subsidiary into the Company in accordance with the terms of this Agreement and the General Corporation Law of the State of Delaware (the “DGCL”), as a result of which the Company shall become a wholly owned subsidiary of the Parent;

WHEREAS, concurrently with the execution and delivery of this Agreement and as a condition and inducement to the Parent’s willingness to enter into this Agreement, the stockholders of the Company listed on Schedule A have entered into Stockholder Agreements, dated as of the date of this Agreement, in the form attached hereto as Exhibit A (the “Company Stockholder Agreements”), pursuant to which such stockholders have, among other things, agreed to give the Parent a proxy to vote all of the shares of capital stock of the Company that such stockholders own;

WHEREAS, concurrently with the execution and delivery of this Agreement and as a condition and inducement to the Company’s willingness to enter into this Agreement, the shareholders of the Parent listed on Schedule B have entered into Shareholder Agreements, dated as of the date of this Agreement, in the form attached hereto as Exhibit B (the “Parent Shareholder Agreements”), pursuant to which such shareholders have, among other things, agreed to give the Company a proxy to vote all of the shares of capital stock of the Parent that such shareholders own;

WHEREAS, for United States federal income tax purposes, it is intended that the Merger shall qualify as a reorganization within the meaning of Section 368(a) of the United States Internal Revenue Code of 1986, as amended (the “Code”); and

WHEREAS, immediately prior to the Effective Time, the Company intends to distribute the Cash Amount (as defined herein) to the holders of Company Common Stock outstanding on the Distribution Record Date, as defined below (the “Distribution”).

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parent, the Transitory Subsidiary and the Company agree as follows:

ARTICLE I

THE MERGER

1.1 Effective Time of the Merger. Subject to the provisions of this Agreement, prior to the Closing, the Parent shall prepare, and on the Closing Date or as soon as practicable thereafter the Parent shall cause to be filed with the Secretary of State of the State of Delaware, a certificate of merger (the “Certificate of Merger”) in such form as is required by, and executed by the Surviving Corporation in accordance with, the relevant provisions of the DGCL and shall make all other filings or recordings required under the DGCL. The Merger shall become effective upon the filing of the Certificate of Merger with the Secretary of State of the State of Delaware or at such later time as is established by the Parent and the Company and set forth in the Certificate of Merger (the “Effective Time”).

1.2 Closing. The closing of the Merger (the “Closing”) shall take place at 10:00 a.m., Eastern time, on a date to be specified by the Parent and the Company (the “Closing Date”), which shall be no later than the second business day after satisfaction or waiver of the conditions set forth in Article VII (other than delivery of items to be delivered at the Closing and other than satisfaction of those conditions that by their nature are to be satisfied at the Closing, it being understood that the occurrence of the Closing shall remain subject to the delivery of such items and the satisfaction or waiver of such conditions at the Closing), at the offices of Wilson, Sonsini, ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇, Professional Corporation, ▇▇▇ ▇▇▇▇ ▇▇▇▇ ▇▇▇▇, ▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, unless another date, place or time is agreed to in writing by the Parent and the Company.

1.3 Effects of the Merger. At the Effective Time (i) the separate existence of the Transitory Subsidiary shall cease and the Transitory Subsidiary shall be merged with and into the Company (the Company following the Merger is sometimes referred to herein as the “Surviving Corporation”), (ii) the Certificate of Incorporation of the Company as in effect on the date of this Agreement shall be amended so that Article FOURTH of such Certificate of Incorporation reads in its entirety as follows: “The total number of shares of all classes of stock which the Corporation shall have authority to issue is 1,000, all of which shall consist of common stock, $.01 par value per share,” and, as so amended, such Certificate of Incorporation shall be the Certificate of Incorporation of the Surviving Corporation, until further amended in accordance with the DGCL, and (iii) the directors and officers of the Transitory Subsidiary immediately prior to the Effective Time shall be the initial directors and officers of the Surviving Corporation, each to hold office in accordance with the Certificate of Incorporation and By-laws of the Surviving Corporation. In addition, the Parent shall cause the By-laws of the Company to be amended and restated in their entirety immediately following the Effective Time so that they are identical to the By-laws of the Transitory Subsidiary as in effect immediately prior to the Effective Time, except that all references to the name of the Transitory Subsidiary therein shall be changed to refer to the name of the Company, and, as so amended and restated, such By-laws shall be the By-laws of the Surviving Corporation, until further amended in accordance with the DGCL and such By-laws. The Merger shall have the effects set forth in Section 259 of the DGCL.

ARTICLE II

CONVERSION OF SECURITIES AND
DISTRIBUTION OF THE CASH AMOUNT

2.1 Conversion of Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of the capital stock of the Company or capital stock of the Transitory Subsidiary:

(a) Capital Stock of the Transitory Subsidiary. Each share of the common stock of the Transitory Subsidiary issued and outstanding immediately prior to the Effective Time shall be converted into and become one fully paid and nonassessable share of common stock, US $.01 par value per share, of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Parent-Owned Stock. All shares of common stock, US $0.001 par value per share, of the Company (“Company Common Stock”) that are owned by the Company as treasury stock or by any wholly owned Subsidiary of the Company and any shares of Company Common Stock owned by the Parent, the Transitory Subsidiary or any other wholly owned Subsidiary of the Parent immediately prior to the Effective Time shall be cancelled and shall cease to exist and no stock of the Parent or other consideration shall be delivered in exchange therefor.

(c) Exchange Ratio for Company Common Stock. Subject to Section 2.2, each share of Company Common Stock (other than shares to be cancelled in accordance with Section 2.1(b)) issued and outstanding immediately prior to the Effective Time shall be automatically converted into and represent the right to receive 1.2015 shares (the “Exchange Ratio”) of Parent American Depositary Shares (“Parent ADSs”), each Parent ADS representing one ordinary share, par value 1/3 p per share, of the Parent (“Parent Ordinary Shares”) or, at the election of the holder of Company Common Stock, the equivalent number of Parent Ordinary Shares in registered certificated or uncertificated form, upon surrender of the certificate representing such share of Company Common Stock in the manner provided in Section 2.2; provided that if a holder of Company Common Stock does not make such election on the letter of transmittal forwarded to such holder pursuant to Section 2.2(b), such holder shall be deemed to have elected to receive Parent ADSs. The Parent ADSs shall be evidenced by one or more American Depository Receipts (“Parent ADRs”) issued in accordance with the Deposit Agreement dated as of April 11, 2000 by and among the Parent, The Bank of New York (the “Depository”) and the holders from time to time of Parent ADRs (the “Deposit Agreement”). As of the Effective Time, all such shares of Company Common Stock shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of a certificate representing any such shares of Company Common Stock shall cease to have any rights with respect thereto, except the right to receive the Parent ADSs pursuant to this Section 2.1(c), any cash in lieu of fractional Parent ADSs to be issued or paid in consideration therefor and any dividends or distributions payable pursuant to Section 2.2(c) upon the surrender of such certificate in accordance with Section 2.2, without interest. For purposes of this Agreement, references to Parent ADSs shall also mean Parent Ordinary Shares that holders of Company Common Stock may elect to receive in lieu of Parent ADSs pursuant to the Merger.

(d) Adjustments to Exchange Ratio. The Exchange Ratio shall be adjusted to reflect fully the effect of any reclassification, stock split, consolidation, reverse split, stock dividend (including any dividend or distribution of securities convertible into Parent Ordinary Shares, Parent ADSs or Company Common Stock), reorganization, capital redemption or repayment, bonus issue, recapitalization or other like change with respect to Parent Ordinary Shares, Parent ADSs or Company Common Stock occurring (or for which a record date is established) after the date hereof and prior to the Effective Time, other than the Distribution.

(e) Unvested Stock. At the Effective Time, any Parent ADSs issued in accordance with Section 2.1(c) with respect to any unvested shares of Company Common Stock awarded to employees, directors or consultants pursuant to any of the Company’s plans or arrangements and outstanding immediately prior to the Effective Time shall remain subject to the same terms, restrictions and vesting schedule as in effect immediately prior to the Effective Time, except to the extent by their terms as in effect as of the date hereof such unvested shares of Company Common Stock vest at the Effective Time. The Company shall not take or permit any action, which would accelerate vesting of any unvested shares, except to the extent required by their terms as in effect on the date hereof. Copies of the relevant agreements governing such shares and the vesting thereof have been provided to the Parent. All outstanding rights which the Company may hold immediately prior to the Effective Time to repurchase unvested shares of Company Common Stock shall be assigned to the Parent in the Merger and shall thereafter be exercisable by the Surviving Corporation upon the same terms and conditions in effect immediately prior to the Effective Time, except that the shares purchasable and the purchase price payable per share pursuant to such rights shall be appropriately adjusted to reflect the Exchange Ratio. The Company shall take all steps necessary to cause the foregoing provisions of this Section 2.1(e) to occur.

(f) Treatment of Company Stock Options. Following the Effective Time, Company Stock Options shall be treated in the manner set forth in Section 6.13.

2.2 Exchange of Certificates and Distribution of Cash Amount. The procedures for exchanging outstanding shares of Company Common Stock for Parent ADSs pursuant to the Merger and the Distribution of the Cash Amount are as follows:

(a) Exchange Agent. As of the Effective Time, the Parent shall deposit with the Depository, for the benefit of the holders of shares of Company Common Stock, the number of Parent Ordinary Shares as are represented by the Parent ADSs to be issued in connection with Section 2.1. In addition, as of the Effective Time, the Depository shall deposit with Capita plc or another bank or trust company designated by the Parent and reasonably acceptable to the Company (the “Exchange Agent”), for the benefit of the holders of shares of Company Common Stock, for exchange in accordance with this Section 2.2, through the Exchange Agent, Parent ADSs (such Parent ADSs, together with any dividends or distributions with respect to the Parent Ordinary Shares underlying such Parent ADSs with a record date after the Effective Time, being hereinafter referred to as the “Exchange Fund”) issuable pursuant to Section 2.1 in exchange for certificates evidencing shares of Company Common Stock outstanding as of the Effective Time (“Certificates”). At the Effective Time, the Parent shall also deposit with the Exchange Agent for the benefit of the holders of shares of Company Common Stock, for exchange in accordance

with this Section 2.2, through the Exchange Agent cash in an amount sufficient to make payments for fractional shares required pursuant to Section 2.2(e).

(b) Exchange Procedures. As soon as reasonably practicable and in any event within ten (10) business days after the Effective Time, the Parent shall cause the Exchange Agent to mail to each holder of record of a Certificate (i) a letter of transmittal (which shall (A) include a form of election by which each such holder may elect to receive the merger consideration to which such holder is entitled in the form of Parent ADSs or Parent Ordinary Shares in registered form and (B) specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as the Parent may reasonably specify) and (ii) instructions for effecting the surrender of the Certificates in exchange for Parent ADRs (plus cash in lieu of fractional shares, if any, of Parent ADSs and any dividends or distributions as provided below) or certificates representing Parent Ordinary Shares. Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by the Parent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor a Parent ADR representing that number of whole Parent ADSs or a certificate representing that number of Parent Ordinary Shares which such holder has the right to receive pursuant to the provisions of this Article II plus cash in lieu of fractional shares pursuant to Section 2.2(e) and any dividends or distributions then payable pursuant to Section 2.2(c), and the Certificate so surrendered shall immediately be cancelled. In the event of a transfer of ownership of Company Common Stock which is not registered in the transfer records of the Company, a Parent ADR representing the proper number of Parent ADSs or a certificate representing the proper number of Parent Ordinary Shares issuable in exchange therefor pursuant to this Article II plus cash in lieu of fractional shares pursuant to Section 2.2(e) and any dividends or distributions then payable pursuant to Section 2.2(c) may be issued or paid to a person other than the person in whose name the Certificate so surrendered is registered, if such Certificate is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 2.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Parent ADR representing Parent ADSs or certificates representing Parent Ordinary Shares plus cash in lieu of fractional shares pursuant to Section 2.2(e) and any dividends or distributions then payable pursuant to Section 2.2(c) as contemplated by this Section 2.2.

(c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made after the Effective Time with respect to Parent ADSs with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate until the holder of record of such Certificate shall surrender such Certificate. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be issued and paid to the record holder of the Certificate, at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time previously paid with respect to such whole Parent ADSs, without interest, and, at the appropriate payment date, the amount of dividends or other distributions having a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender that are payable with respect to such whole Parent ADSs.

(d) No Further Ownership Rights in Company Common Stock. All Parent ADSs issued upon the surrender for exchange of Certificates in accordance with the terms hereof (including any cash or dividends or other distributions paid pursuant to Sections 2.2(c) or 2.2(e)) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to such shares of Company Common Stock, and from and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article II.

(e) No Fractional Shares. No Parent ADRs or scrip representing fractional shares of Parent ADSs, or if applicable certificates representing Parent Ordinary Shares, shall be issued upon the surrender for exchange of Certificates, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of the Parent. Notwithstanding any other provision of this Agreement, each holder of shares of Company Common Stock converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a Parent ADS (after taking into account all Certificates delivered by such holder and the aggregate number of shares of Company Common Stock represented thereby) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a Parent ADS multiplied by the average of the last reported sales prices of Parent ADSs at the 4:00 p.m., Eastern time, end of regular trading hours on The NASDAQ Stock Market during the ten consecutive trading days ending on the last trading day prior to the Effective Time.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Company Common Stock for 12 months after the Effective Time shall be delivered to the Parent, upon demand, and any holder of Company Common Stock who has not previously complied with this Section 2.2 shall thereafter look only to the Parent, as a general unsecured creditor, for payment of its claim for Parent ADSs, any cash in lieu of fractional shares of Parent ADSs and any dividends or distributions with respect to Parent ADSs.

(g) No Liability. To the extent permitted by applicable law, none of the Parent, the Transitory Subsidiary, the Company, the Surviving Corporation or the Exchange Agent shall be liable to any holder of shares of Company Common Stock, Parent Ordinary Shares or Parent ADSs, as the case may be, for such shares (or dividends or distributions with respect thereto) delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate shall not have been surrendered prior to the date that is 18 months after the Effective Time (or immediately prior to such earlier date on which any Parent ADSs and any cash payable to the holder of such Certificate or any dividends or distributions payable to the holder of such Certificate pursuant to this Article II would otherwise escheat to or become the property of any Governmental Entity), any such Parent ADSs and the underlying Parent Ordinary Shares, or cash, dividends or distributions in respect of such Certificate shall, to the extent permitted by applicable law, become the property of the Parent, free and clear of all claims or interest of any person previously entitled thereto.

(h) Withholding Rights. Notwithstanding any other provision in this Agreement, each of the Parent, the Surviving Corporation and the Company shall be entitled to deduct and withhold from the payments to be made pursuant to this Agreement such amounts as it reasonably determines that it is required to deduct and withhold with respect to the making of such payments under the Code or any other applicable provision of law and to collect Forms W-8 or W-9, as applicable, or similar information from the holders of Company Common Stock and any other recipients of payments hereunder. To the extent that amounts are so withheld by the Company, the Surviving Corporation or the Parent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by the Company, the Surviving Corporation or the Parent, as the case may be.

(i) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such person of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificate the Parent ADSs and any cash in lieu of fractional shares, and unpaid dividends and distributions on Parent Ordinary Shares deliverable in respect thereof pursuant to this Agreement.

(j) Distribution of the Cash Amount. Subject to the provisions of Section 6.22, (A) prior to the Effective Time, the Company shall deliver the Cash Amount to EquiServe and (B) immediately prior to the Effective Time, the Company shall effect the Distribution and EquiServe shall deliver to each holder of Company Common Stock on the Distribution Record Date, a check in the amount of the Cash Amount Per Share. For the purposes of this Agreement, the following terms shall have the following meanings:

(i) “Cash Amount” shall equal the product of (A) the Cash Amount Per Share and (B) the number of shares of Company Common Stock issued and outstanding as of the Distribution Record Date.

(ii) “Cash Amount Per Share” shall equal US $2.19.

(iii) “Distribution Record Date” means the close of business on the date to be determined by the Board of Directors of the Company as the record date for determining stockholders of the Company entitled to receive a share of the Distribution.

For purposes of this Agreement, the term “Company Material Adverse Effect” means any material adverse change, event, circumstance or development with respect to, or material adverse effect on (i) the business, assets, liabilities, capitalization, financial condition, or results of operations of the Company and its Subsidiaries, taken as a whole, or (ii) the ability of the Company to consummate the transactions contemplated by this Agreement; provided, however, that in the case of clause (i), in no event shall any of the following, alone or in combination, be deemed to constitute, nor shall any of the following be taken into account in determining whether there has occurred, a Company Material Adverse Effect: any adverse change, event, circumstance or development with respect to, or effect resulting from (A) general economic conditions or conditions generally affecting the semiconductor capital equipment and the test and measurement industries, except to the extent the Company is materially disproportionately affected thereby, (B) the announcement or pendency of the Merger or any other transactions expressly contemplated hereby, (C) compliance with the express terms and conditions of this Agreement, (D) a change in the stock price or trading volume of the Company (or any failure of the Company to meet published revenue or earnings projections), provided that clause (D) shall not exclude any underlying effect which may have caused such change in stock price or trading volume or failure to meet published revenue or earnings projections, (E) any change in accounting requirements or principles or any change in applicable laws, rules or regulations or the interpretation thereof or (F) the continued incurrence of losses by the Company. For the avoidance of doubt, the parties agree that the terms “material”, “materially” or “materiality” as used in this Agreement with an initial lower case “m” shall have their respective customary and ordinary meanings, without regard to the meanings ascribed to Company Material Adverse Effect in the prior sentence of this paragraph or Parent Material Adverse Effect in Section 4.1.

REPRESENTATIONS AND WARRANTIES OF THE PARENT AND THE
TRANSITORY SUBSIDIARY

The Parent and the Transitory Subsidiary represent and warrant to the Company that the statements contained in this Article IV are true and correct, except as expressly set forth herein or in the disclosure schedule delivered by the Parent and the Transitory Subsidiary to the Company on or before the date of this Agreement (the “Parent Disclosure Schedule”). The Parent Disclosure Schedule shall be arranged in paragraphs corresponding to the numbered and lettered paragraphs contained in this Article IV and the disclosure in any paragraph shall qualify (1) the corresponding paragraph in this Article IV and (2) the other paragraphs in this Article IV only to the extent such disclosure reasonably appears on its face to be applicable to such other paragraphs.

4.1 Organization, Standing and Power.

(a) Each of the Parent and the Transitory Subsidiary is a corporation duly organized, validly existing and, where applicable as a legal concept, in good standing under the laws of the jurisdiction of its incorporation, has all requisite corporate power and authority to own, lease and operate its properties and assets and to carry on its business as now being conducted and as proposed to be conducted, and is duly qualified to do business and is in good standing as a foreign corporation in each jurisdiction in which the character of the properties it owns, operates or leases or the nature of its activities makes such qualification necessary, except for such failures to be so organized, qualified or in good standing, individually or in the aggregate, that have not had a Parent Material Adverse Effect. For purposes of this Agreement, the term “Parent Material Adverse Effect” means any material adverse change, event, circumstance or development with respect to, or material adverse effect on (i) the business, assets, liabilities, capitalization, financial condition, or results of operations of the Parent and its Subsidiaries, taken as a whole or (ii) the ability of the Parent or the Transitory Subsidiary to consummate the transactions contemplated by this Agreement; provided, however, that in the case of clause (i), in no event shall any of the following, alone or in combination, be deemed to constitute, nor shall any of the following be taken into account in determining whether there has occurred, a Parent Material Adverse Effect: any adverse change, event, circumstance or development with respect to, or effect resulting from (A) general economic conditions or conditions generally affecting the optical networking industry, except in either case to the extent the Parent is materially disproportionately affected thereby, (B) the announcement or pendency of the Merger or any other transactions expressly contemplated hereby, (C) compliance with the terms and conditions of this Agreement, (D) a change in the stock price or trading volume of the Parent Ordinary Shares or Parent ADSs (or any failure of the Parent to meet published revenue or earnings projections), provided that clause (D) shall not exclude any underlying effect which may have caused such change in stock price or trading volume or failure to meet published revenue or earnings projections, (E) any change in accounting requirements or principles or any

change in applicable laws, rules or regulations or the interpretation thereof or (F) the continued incurrence of losses by the Parent. For the avoidance of doubt, the parties agree that the terms “material”, “materially” or “materiality” as used in this Agreement with an initial lower case “m” shall have their respective customary and ordinary meanings, without regard to the meanings ascribed to Parent Material Adverse Effect in the prior sentence of this paragraph or Company Material Adverse Effect in Section 3.1(a).

(b) The execution and delivery of this Agreement and consummation of the Merger will not result in the breach of, or create on behalf of any third party the right to terminate or modify, (i) Parent Intellectual Property or (ii) any license, sublicense and other agreement as to which the Parent or any of its Subsidiaries is a party and pursuant to which the Parent or any of its Subsidiaries is authorized to use any third party Intellectual Property that is material to the business of the Parent and its Subsidiaries, taken as a whole, including software that is used in the manufacture of, incorporated in, or forms a part of any product or service sold by or expected to be sold by the Parent or any of its Subsidiaries (the “Parent Third Party Intellectual Property”).

(b) Without limiting any obligation under 6.15(a), for a period of six years after the Effective Time, the Parent shall cause the Surviving Corporation to maintain (to the extent available in the market) in effect a directors’ and officers’ liability insurance policy covering those persons who are currently covered by the Company’s directors’ and officers’ liability insurance policy (a complete and accurate copy of which has been delivered to the Parent prior to the date of this Agreement) with coverage in amount and scope at least as favorable to such persons as the Company’s existing coverage; provided, however, that in no event shall the Parent or the Surviving Corporation be required to expend in excess of one

54 hundred seventy five percent (175%) of the annual premium currently paid by the Company for such coverage, and to the extent the annual premium would exceed one hundred seventy five percent (175%) of such current annual premium, the Parent or Surviving Corporation shall use all reasonable efforts to be maintained the maximum amount of coverage available for such one hundred seventy five percent (175%) of such current annual premium. The Company hereby represents that the annual premium currently paid by the Company for such coverage is US $1,411,618.

(c) The provisions of this Section 6.15 are intended to be in addition to the rights otherwise available to the current officers and directors of the Company by law, charter, statute, by-law or agreement, and shall operate for the benefit of, and shall be enforceable by, each of the Indemnified Parties, their heirs and their representatives. The obligations of the Company and Surviving Corporation under this Section 6.15 shall be binding upon their respective successors and assigns.

6.16 Notification of Certain Matters. The Parent shall give notice to the Company, and the Company shall give notice to the Parent, promptly upon any director or officer of the Parent or Company (as applicable) becoming aware of the occurrence, or failure to occur, of any event, which occurrence or failure to occur would be reasonably likely to cause (a) (i) any representation or warranty of such party contained in this Agreement that is qualified as to materiality to be untrue or inaccurate in any respect or (ii) any other representation or warranty of such party contained in this Agreement to be untrue or inaccurate in any material respect, in each case at any time from and after the date of this Agreement until the Effective Time, or (b) any material failure of the Parent and the Transitory Subsidiary or the Company, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement. Notwithstanding the above, (i) the delivery of any notice pursuant to this Section will not limit or otherwise affect the remedies available hereunder to the party receiving such notice or the conditions to such party’s obligation to consummate the Merger and (ii) any breach of a representation or warranty by the Parent or the Company, as applicable, that does not itself give rise to a failure to satisfy the conditions set forth in Section 7.2(a) or 7.3(a) of this Agreement, as applicable, shall not give the non-breaching party the right to terminate this Agreement pursuant to Section 8(h) or Section 8(i) of this Agreement, as applicable.

The Company and the Parent covenant that they shall thereafter negotiate in good faith to restructure the transactions contemplated by this Agreement, such that the Company stockholders shall receive consideration composed of cash and shares corresponding to the consideration contemplated by the provisions of this Agreement, in conformity with applicable law and, provided that the conditions set forth in Article VII, other than the conditions set forth in Sections 7.1(h) and 7.2(d), which shall be deemed to have been satisfied or waived, shall continue to be the obligations of the parties hereunder pursuant to such restructuring.

(g) by the Company, if: (i) the Parent shall have materially breached its obligations under Sections 6.2 or 6.6; or (ii) for any reason the Parent shall have failed to hold the Parent Shareholders Meeting and submit the Parent Voting Proposal to the Parent’s shareholders by the date which is five business days prior to the Outside Date; or

(h) by the Parent, if there has been a breach of or failure to perform any representation, warranty, covenant or agreement on the part of the Company set forth in this Agreement, which breach or failure to perform (i) would cause the conditions set forth in Sections 7.2(a) or 7.2(b) not to be satisfied, and (ii) if curable, shall not have been cured within 20 days following receipt by the Company of written notice of such breach or failure to perform from the Parent; or

(ii) by the Parent pursuant to Section 8.1(f); or

(iii) by the Parent or the Company pursuant to Section 8.1(d) if (A) at or prior to the time of such failure, there shall have been publicly announced a Company Acquisition Proposal which shall not have been absolutely and unconditionally withdrawn and abandoned and (B) on or before the date 12 months following the date of such termination of this Agreement, the Company enters into an Alternative Acquisition Agreement or consummates an Alternative Acquisition Proposal; provided, however, that if, at the time of termination, there is pending a Company Acquisition Proposal that does not involve a liquidation or dissolution of the Company, the Company shall be permitted to be undertake a complete liquidation or dissolution in lieu of such Company Acquisition Proposal and, under such circumstances, the Company shall not be obligated to make any payment of a termination fee to the Parent under this Section 8.3(b); provided, however, that if a Company Acquisition Proposal and any liquidation or dissolution are a part of a series of related transactions, the Company shall be obligated to pay the termination fee provided for hereunder to the Parent. For the purposes of this Section 8.3(b) only, all references in the definition of “Company Acquisition Proposal” to “15%” shall be deemed to be references to “30%.”

8.4 Amendment. This Agreement may be amended by the parties hereto, by action taken or authorized by their respective Boards of Directors, at any time before or after approval of the matters presented in connection with the Merger by the stockholders of any party, but, after any such approval, no amendment shall be made which by law requires further approval by such stockholders without such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

8.5 Extension; Waiver.

Any party to this Agreement may give any notice or other communication hereunder using any other means (including personal delivery, messenger service, telecopy, telex, ordinary mail or electronic mail), but no such notice or other communication shall be deemed to have been duly given unless and until it actually is received by the party for whom it is intended. Any party to this Agreement may change the address to which notices and other communications hereunder are to be delivered by giving the other parties to this Agreement notice in the manner herein set forth.

9.3 Entire Agreement. This Agreement (including the Schedules and Exhibits hereto and the documents and instruments referred to herein that are to be delivered at the Closing as well as the Company Stockholder Agreements and the Parent Shareholder Agreements)

constitutes the entire agreement among the parties to this Agreement and supersedes any prior understandings, agreements or representations by or among the parties hereto, or any of them, written or oral, with respect to the subject matter hereof; provided that the Confidentiality Agreement shall remain in effect in accordance with its terms.

9.4 No Third Party Beneficiaries. Except as provided in Section 6.15, this Agreement is not intended, and shall not be deemed, to confer any rights or remedies upon any person other than the parties hereto and their respective successors and permitted assigns, to create any agreement of employment with any person or to otherwise create any third-party beneficiary hereto.

9.5 Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned or delegated, in whole or in part, by operation of law or otherwise by any of the parties hereto without the prior written consent of the other parties, and any such assignment without such prior written consent shall be null and void, except that the Parent and/or the Transitory Subsidiary may assign this Agreement to any direct or indirect wholly owned Subsidiary of the Parent without consent of the Company (and the parties hereto shall execute and deliver any amendment to this Agreement necessary to effect such assignment), provided that the Parent and/or the Transitory Subsidiary, as the case may be, shall remain liable for all of its obligations under this Agreement. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and permitted assigns.

9.6 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

9.7 Counterparts and Signature. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original but all of which together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties hereto and delivered to the other parties, it being understood that all parties need not sign the same counterpart. This Agreement may be executed and delivered by facsimile transmission.

9.8 Interpretation. When reference is made in this Agreement to an Article or a Section, such reference shall be to an Article or Section of this Agreement, unless otherwise indicated. The table of contents, table of defined terms and headings contained in this

Agreement are for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement. The language used in this Agreement shall be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction shall be applied against any party. Whenever the context may require, any pronouns used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns and pronouns shall include the plural, and vice versa. Any reference to any federal, state, local or foreign statute or law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. Whenever the words “include”, “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation”. No summary of this Agreement prepared by any party shall affect the meaning or interpretation of this Agreement.

9.9 Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of laws of any jurisdictions other than those of the State of Delaware.

9.10 Remedies. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which they are entitled at law or in equity.

9.11 Submission to Jurisdiction.

Any party hereto may make service on another party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for the giving of notices in Section 9.2. Nothing in this Section 9.11, however, shall affect the right of any party to serve legal process in any other manner permitted by law.

67 9.12 Waiver of Jury Trial. Each of the Parent, the Transitory Subsidiary and the Company hereby irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the transactions contemplated hereby or the actions of the Parent, the Transitory Subsidiary or the Company in the negotiation, administration, performance and enforcement of this Agreement.
