The Merger
     Section 2.01. The Merger. (a) At the Effective Time, Merger Subsidiary shall be merged (the “Merger”) with and into the Company in accordance with Delaware Law and Massachusetts Law, whereupon the separate existence of Merger Subsidiary shall cease, and the Company shall be the surviving corporation (the “Surviving Corporation”).
     (b) As soon as practicable (and in any event not later than two Business Days) after satisfaction or, to the extent permitted hereunder, waiver of all conditions to the Merger set forth in Article 9, other than conditions that by their

7


 

nature are to be satisfied at the Closing and will in fact be satisfied or waived at the Closing, the Company and Merger Subsidiary shall file a certificate of merger and articles of merger with the Delaware Secretary of State and the Massachusetts Secretary of State, respectively, and make all other filings or recordings required by Delaware Law and Massachusetts Law in connection with the Merger. The Merger shall become effective at such time (the “Effective Time”) as the certificate of merger and the articles of merger are duly filed with the Delaware Secretary of State and the Massachusetts Secretary of State in accordance with Delaware Law and Massachusetts Law.
     (c) From and after the Effective Time, the Surviving Corporation shall possess all the rights, powers, privileges and franchises and be subject to all of the obligations, liabilities, restrictions and disabilities of the Company and Merger Subsidiary, all as provided under Delaware Law and Massachusetts Law.
     (d) Upon the terms and subject to the conditions set forth herein, the consummation of the Merger (the “Closing”) will take place on the date on which the Effective Time occurs, unless this Agreement has been theretofore terminated pursuant to its terms or unless another time or date is agreed to in writing by the parties hereto. The Closing shall be held at the offices of Sullivan & Worcester LLP, One Post Office Square, Boston, Massachusetts 02109, unless another place is agreed to in writing by the parties hereto.
     Section 2.02. Conversion of Shares. At the Effective Time:
     (a) except as otherwise provided in Sections 2.05 and 2.06, each share of Company Common Stock outstanding immediately prior to the Effective Time shall be converted into the right to receive the number of shares of Parent Common Stock represented by the Exchange Ratio (together with the cash in lieu of fractional shares of Parent Stock as specified in Section 2.06, the “Merger Consideration”);
     (b) each share of Company Common Stock held by the Company as treasury stock or owned by Parent or any of its Subsidiaries immediately prior to the Effective Time shall be canceled, and no payment shall be made with respect thereto;
     (c) each share of common stock of Merger Subsidiary outstanding immediately prior to the Effective Time shall be converted into and become one share of common stock of the Surviving Corporation with the same rights, powers and privileges as the shares so converted and shall constitute the only outstanding shares of capital stock of the Surviving Corporation; and
     (d) the shares of Parent Common Stock to be issued as part of the Merger Consideration will have been duly authorized and, when issued and delivered in accordance with the terms of this Agreement, will have been validly

8


 

issued and will be fully paid and nonassessable and the issuance thereof will not be subject to any preemptive or other similar right.
     Section 2.03. Surrender and Payment. (a) Prior to the Effective Time, Parent shall appoint an agent (the “Exchange Agent”) for the purpose of exchanging for the Merger Consideration (i) certificates representing shares of Company Common Stock (the “Certificates”) or (ii) uncertificated shares of Company Common Stock (the “Uncertificated Shares”). Promptly (and in any event within five Business Days) after the Effective Time, Parent shall make available to the Exchange Agent, the Merger Consideration to be paid in respect of the Certificates and the Uncertificated Shares. Promptly (and in any event within five Business Days) after the Effective Time, Parent shall send, or shall cause the Exchange Agent to send, to each holder of shares of Company Common Stock at the Effective Time a letter of transmittal and instructions (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or transfer of the Uncertificated Shares to the Exchange Agent) for use in such exchange.
     (b) Each holder of shares of Company Common Stock that have been converted into the right to receive the Merger Consideration shall be entitled to receive, upon (i) surrender to the Exchange Agent of a Certificate, together with a properly completed letter of transmittal, or (ii) receipt of an “agent’s message” by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the Merger Consideration in respect of the Company Common Stock represented by a Certificate or Uncertificated Share. The shares of Parent Common Stock included in such Merger Consideration, at Parent’s option, shall be in uncertificated book-entry form, unless a physical certificate is requested by a holder of shares of Company Common Stock or is otherwise required under Applicable Law. Until so surrendered or transferred, as the case may be, each such Certificate or Uncertificated Share shall represent after the Effective Time for all purposes only the right to receive such Merger Consideration.
     (c) If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name the surrendered Certificate or the transferred Uncertificated Share is registered, it shall be a condition to such payment that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Uncertificated Share shall be properly transferred and (ii) the Person requesting such payment shall pay to the Exchange Agent any transfer or other taxes required as a result of such payment to a Person other than the registered holder of such Certificate or Uncertificated Share or establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

9


 

     (d) After the Effective Time, there shall be no further registration of transfers of shares of Company Common Stock. If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation, they shall be canceled and exchanged for the Merger Consideration provided for, and in accordance with the procedures set forth, in this Article 2.
     (e) Any portion of the Merger Consideration made available to the Exchange Agent pursuant to Section 2.03(a) that remains unclaimed by the holders of shares of Company Common Stock twelve months after the Effective Time shall be returned to Parent, upon demand, and any such holder who has not exchanged shares of Company Common Stock for the Merger Consideration in accordance with this Section 2.03 prior to that time shall thereafter look only to Parent for payment of the Merger Consideration, and any dividends and distributions with respect thereto, in respect of such shares without any interest thereon. Notwithstanding the foregoing, Parent shall not be liable to any holder of shares of Company Common Stock for any amounts paid to a public official pursuant to applicable abandoned property, escheat or similar laws. Any amounts remaining unclaimed by holders of shares of Company Common Stock two years after the Effective Time (or such earlier date, immediately prior to such time when the amounts would otherwise escheat to or become property of any Governmental Authority) shall become, to the extent permitted by Applicable Law, the property of Parent free and clear of any claims or interest of any Person previously entitled thereto.
     (f) No dividends or other distributions with respect to securities of Parent constituting part of the Merger Consideration, and no cash payment in lieu of fractional shares as provided in Section 2.06, shall be paid to the holder of any Certificates not surrendered or of any Uncertificated Shares not transferred until such Certificates or Uncertificated Shares are surrendered or transferred, as the case may be, as provided in this Section. Following such surrender or transfer, there shall be paid, without interest, to the Person in whose name the securities of Parent have been registered, (i) at the time of such surrender or transfer, the amount of any cash payable in lieu of fractional shares to which such Person is entitled pursuant to Section 2.06 and the amount of all dividends or other distributions with a record date after the Effective Time previously paid or payable on the date of such surrender with respect to such securities, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time and prior to surrender or transfer and with a payment date subsequent to surrender or transfer payable with respect to such securities.
     Section 2.04. Stock Options. (a) Subject to Section 2.04(b), as of the Effective Time, each stock option outstanding under any stock option or compensation plan, agreement or arrangement of the Company (each, a “Company Stock Option”) that is outstanding immediately prior to the Effective

10


 

Time, whether or not then vested or exercisable, shall cease to represent a right to acquire Company Common Stock and shall be converted automatically into an option to purchase shares of Parent Common Stock on substantially the same terms and conditions (including vesting schedule) as applied to such Company Stock Option immediately prior to the Effective Time, except that (i) the number of shares of Parent Common Stock subject to each assumed Company Stock Option shall be determined by multiplying (A) the number of shares of Company Common Stock subject to such Company Stock Option by (B) the Exchange Ratio (such product to be rounded down to the nearest whole share); and (ii) the per share exercise price for the shares of Parent Common Stock issuable upon exercise of such assumed Company Stock Option will be equal to the quotient determined by dividing (A) the per share exercise price for the shares of Company Common Stock in respect of which such Company Stock Option was exercisable immediately prior to the Effective Time by (B) the Exchange Ratio.
     (b) At or immediately prior to the Effective Time, each Company Stock Option held by a non-employee director or former director of the Company outstanding under any employee stock option or compensation plan or arrangement of the Company, whether or not exercisable or vested, shall be canceled, and the Company shall pay each such holder at or promptly after the Effective Time for each such option an amount in cash determined by multiplying (i) the excess, if any, of (A) the Exchange Ratio multiplied by the closing price per share of Parent Common Stock on the Nasdaq (as reported by Bloomberg Financial markets or such other source as the parties shall agree in writing) on the Business Day immediately prior to the Closing Date over (B) the applicable exercise price of such option by (ii) the number of shares of Company Common Stock such holder could have purchased (assuming full vesting of all options) had such holder exercised such option in full immediately prior to the Effective Time.
     (c) Prior to the Effective Time, the Company shall (i) use its commercially reasonable efforts to obtain any consents from holders of options to purchase shares of Company Common Stock granted under the Company’s stock option or compensation plans or arrangements and (ii) make any amendments to the terms of such stock option or compensation plans or arrangements that are necessary to give effect to the transactions contemplated by this Section 2.04. Notwithstanding any other provision of this Section 2.04, payment may be withheld in respect of any employee stock option until such necessary consents are obtained.
     (d) Parent shall take such actions as are necessary for the assumption of Company Stock Options pursuant to this Section 2.04, including the reservation, issuance and listing of Parent Common Stock as is necessary to effectuate the transactions contemplated by this Section 2.04. Parent shall prepare and file with the SEC a registration statement on an appropriate form, or a post-effective amendment to a registration statement previously filed under the 1933 Act, with

11


 

respect to the shares of Parent Common Stock subject to such assumed Company Stock Options and, where applicable, shall use its reasonable best efforts to have such registration statement declared effective as soon as practicable following the Effective Time and to maintain the effectiveness of such registration statement covering such assumed Company Stock Options (and to maintain the current status of the prospectus contained therein) for so long as such Company Stock Options remain outstanding. Parent shall take all actions required under the rules and regulations of the Nasdaq with respect to the assumption by it of the Company Stock Options. It is intended that the Company Stock Options assumed by Parent shall qualify following the Effective Time as incentive stock options (as defined in Section 422 of the Code) to the extent the Company Stock Options qualified as incentive stock options immediately prior to the Effective Time and this Section 2.04 shall be construed consistent with such intent.
     Section 2.05. Adjustments. If, during the period between the date of this Agreement and the Effective Time, there is a reclassification, recapitalization, stock split, split-up or combination, exchange or readjustment of shares of Parent Common Stock or Company Common Stock, or any stock dividend thereon (including any dividend of Parent Common Stock or Company Common Stock or any securities convertible into Parent Common Stock or Company Common Stock) with a record date during such period, the Merger Consideration and any other amounts payable pursuant to this Agreement shall be appropriately adjusted to provide the holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such event.
     Section 2.06. Fractional Shares. No fractional shares of Parent Common Stock shall be issued in the Merger. All fractional shares of Parent Common Stock that a holder of shares of Company Common Stock would otherwise be entitled to receive as a result of the Merger shall be aggregated and if a fractional share results from such aggregation, such holder shall be entitled to receive, in lieu thereof, an amount in cash without interest determined by multiplying (i) the closing price per share of Parent Common Stock on the Nasdaq (as reported by Bloomberg Financial markets or such other source as the parties shall agree in writing) on the Business Day immediately prior to the Closing Date by (ii) the fraction of a share of Parent Common Stock to which such holder would otherwise have been entitled.
     Section 2.07. Withholding Rights. Each of the Surviving Corporation and Parent shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Article 2 such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of federal, state, local or foreign tax law. If the Surviving Corporation or Parent, as the case may be, so withholds amounts, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the

12


 

shares of Company Common Stock in respect of which the Surviving Corporation or Parent, as the case may be, made such deduction and withholding.
     Section 2.08. 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 will issue, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration to be paid in respect of the shares of Company Common Stock represented by such Certificate, as contemplated by this Article 2.
ARTICLE 3

     Section 3.03. Directors and Officers.

The Company has all corporate powers and all governmental licenses, authorizations, permits, consents and approvals required to carry on its business as now conducted, except for those licenses, authorizations, permits, consents and approvals the absence of which would not reasonably be expected to have, individually or in the aggregate, a

13


 

Material Adverse Effect on the Company. The Company is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where such qualification is necessary, except for those jurisdictions where failure to be so qualified would not have, individually or in the aggregate, a Material Adverse Effect on the Company.

The affirmative vote of the holders of two-thirds of the outstanding shares of Company Common Stock is the only vote of the holders of any of the Company’s capital stock necessary in connection with the consummation of the Merger (the “Company Stockholder Approval”). This Agreement constitutes a valid and binding agreement of the Company.
     (b) At a meeting duly called and held, the Company’s Board of Directors has (i) unanimously determined that this Agreement and the transactions contemplated hereby are fair to and in the best interests of the Company’s stockholders, (ii) unanimously approved and adopted this Agreement and the transactions contemplated hereby and (iii) unanimously resolved (subject to Section 6.03) to recommend approval and adoption of this Agreement by its stockholders (such recommendation, the “Company Board Recommendation”).
     Section 4.03. Governmental Authorization. The execution, delivery and performance by the Company of this Agreement and the consummation by the Company of the transactions contemplated hereby require no action by or in respect of, or filing with, any Governmental Authority other than (i) the filing of a certificate of merger and the filing of articles of merger with respect to the Merger with the Delaware Secretary of State and the Massachusetts Secretary of State, respectively, and appropriate documents with the relevant authorities of other states in which the Company is qualified to do business, (ii) compliance with any applicable requirements of the HSR Act and of laws analogous to the HSR Act, (iii) compliance with any applicable requirements of the 1933 Act, the 1934 Act, and any other applicable U.S. state or federal securities laws and (iv) any actions or filings the absence of which would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on the Company or materially to impair the ability of the Company to consummate the transactions contemplated by this Agreement.

14


 

     Section 4.04. Non-Contravention. The execution, delivery and performance by the Company of this Agreement and the consummation of the transactions contemplated hereby do not and will not (i) contravene, conflict with, or result in any violation or breach of any provision of the articles of organization or bylaws of the Company, (ii) assuming compliance with the matters referred to in Section 4.03, contravene, conflict with or result in a violation or breach of any provision of any Applicable Law, (iii) require any consent or other action by any Person under, constitute a default, or an event that, with or without notice or lapse of time or both, would constitute a default, under, or cause or permit the termination, cancellation, acceleration or other change of any right or obligation or the loss of any benefit to which the Company or any of its Subsidiaries is entitled, under any provision of any agreement or other instrument binding upon the Company or any of its Subsidiaries or any license, franchise, permit, certificate, approval or other similar authorization affecting, or relating in any way to, the assets or business of the Company and its Subsidiaries or (iv) result in the creation or imposition of any Lien on any asset of the Company or any of its Subsidiaries, with such exceptions, in the case of each of clauses (iii) and (iv), as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on the Company (taking into account for these purposes only the adverse effects specified in clause (ii) of the definition of Material Adverse Effect) or materially to impair the ability of the Company to consummate the transactions contemplated by this Agreement.
     Section 4.05. Capitalization. (a) The authorized capital stock of the Company consists of 25,000,000 shares of Company Common Stock and 1,000,000 shares of preferred stock, $1.00 par value (the “Company Preferred Stock”). As of February 21, 2006, there were outstanding 14,462,887 shares of Company Common Stock, no shares of Company Preferred Stock and employee stock options to purchase an aggregate of 701,784 shares of Company Common Stock (of which options to purchase an aggregate of 406,430 shares of Company Common Stock were exercisable). All outstanding shares of capital stock of the Company have been, and all shares that may be issued pursuant to the Company Stock Option Plans will be, when issued in accordance with the respective terms thereof, duly authorized and validly issued and are fully paid and nonassessable. No Company Subsidiary owns any shares of capital stock of the Company.

There are no outstanding obligations of the Company or any of its Subsidiaries to repurchase, redeem or otherwise acquire any of the Company Securities.
     Section 4.06. Subsidiaries. (a) Each Subsidiary of the Company is a corporation duly incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation, has all corporate powers and all governmental licenses, authorizations, permits, consents and approvals required to carry on its business as now conducted, except for those licenses, authorizations, permits, consents and approvals the absence of which would not have, individually or in the aggregate, a Material Adverse Effect on the Company. Each such Subsidiary is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where such qualification is necessary, except for those jurisdictions where failure to be so qualified would not have, individually or in the aggregate, a Material Adverse Effect on the Company. All active Subsidiaries of the Company and their respective jurisdictions of incorporation are identified in the Company 10-K.
     (b) All of the outstanding capital stock of, or other voting securities or ownership interests in, each Subsidiary of the Company, is owned by the Company, directly or indirectly, free and clear of any Lien and free of any other limitation or restriction (including any restriction on the right to vote, sell or otherwise dispose of such capital stock or other voting securities or ownership interests).

There are no outstanding obligations of the Company or any of its Subsidiaries to repurchase, redeem or otherwise acquire any of the Company Subsidiary Securities.
     Section 4.07. SEC Filings and the Sarbanes-Oxley Act. (a) The Company has delivered or made available (including through the SEC’s EDGAR system) to Parent (i) the Company’s annual report on Form 10-K for its fiscal year ended April 30, 2005, (ii) its quarterly reports on Form 10-Q for its fiscal quarters ended

     (b) As of its filing date, each Company SEC Document complied as to form in all material respects with the applicable requirements of the 1933 Act and the 1934 Act, as the case may be.
     (c) As of its filing date (or, if amended or superseded by a filing prior to the date hereof, on the date of such filing), each Company SEC Document filed pursuant to the 1934 Act did not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. The representations and warranties contained in this Section 4.07(c) will not apply to statements or omissions in the Proxy Statement or any amendment or supplement thereto based upon information furnished to the Company by Parent or Merger Subsidiary in writing specifically for use therein.
     (d) Each Company SEC Document that is a registration statement, as amended or supplemented, if applicable (including through incorporation by reference of other Company SEC Documents), filed pursuant to the 1933 Act, as of the date such registration statement or amendment became effective, did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading.
     (e) The Company has established and maintains disclosure controls and procedures (as defined in Rule 13a-15 under the 1934 Act). Such disclosure controls and procedures are designed to ensure that material information relating to the Company, including its consolidated Subsidiaries, is made known to the Company’s principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the 1934 Act are being prepared. Such disclosure controls and procedures are effective in timely alerting the Company’s principal executive officer and principal financial officer to material information required to be included in the Company’s periodic reports required under the 1934 Act.
     (f) The Company and its Subsidiaries have established and maintained a system of internal control over financial reporting (as defined in Rule 13a-15 under the 1934 Act) (“Internal Controls”). Such Internal Controls are sufficient to provide reasonable assurance regarding the reliability of the Company’s financial reporting and the preparation of Company financial statements for external purposes in accordance with GAAP. The Company has disclosed, based on its most recent evaluation of Internal Controls prior to the date hereof, to the

17


 

Company’s auditors and audit committee (i) any significant deficiencies and material weaknesses in the design or operation of Internal Controls which are reasonably likely to adversely affect the Company’s ability to record, process, summarize and report financial information and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in Internal Controls. The Company has made available to Parent a summary of any such disclosure made by management to the Company’s auditors and audit committee since May 1, 2002.
     (g) There are no outstanding loans or other extensions of credit made by the Company or any of its Subsidiaries to any executive officer (as defined in Rule 3b-7 under the 1934 Act) or director of the Company. The Company has not, since the enactment of the Sarbanes-Oxley Act, taken any action prohibited by Section 402 of the Sarbanes-Oxley Act.
     Section 4.08. Financial Statements. The audited consolidated financial statements and unaudited consolidated interim financial statements of the Company included in the Company SEC Documents fairly present, in conformity with GAAP applied on a consistent basis (except as may be indicated in the notes thereto), the consolidated financial position of the Company and its consolidated Subsidiaries as of the dates thereof and their consolidated results of operations and cash flows for the periods then ended (subject to normal year-end adjustments and the condensed nature of footnote disclosure in the case of any unaudited interim financial statements).
     Section 4.09. Disclosure Documents. (a) The information to be supplied by the Company for inclusion in the registration statement on Form S-4 pursuant to which shares of Parent Common Stock issued in connection with the Merger will be registered under the 1933 Act (the “Registration Statement”) shall not, at the time the Registration Statement is declared effective by the SEC, at the time the prospectus contained therein or any amendment or supplement thereto is first mailed to stockholders of the Company, at the time of the Company Stockholder Meeting or at the Effective Time, contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements in the Registration Statement, in light of the circumstances under which they were made, not misleading.
     (b) The proxy statement (the “Proxy Statement”) to be sent to the stockholders of the Company in connection with the Company Stockholder Meeting shall not, at the time the Proxy Statement or any amendment or supplement thereto is first mailed to the stockholders of the Company or at the time of the Company Stockholder Meeting, contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. The representations and warranties contained in this

18


 

Section 4.09(b) will not apply to statements or omissions in the Proxy Statement or any amendment or supplement thereto based upon information furnished to the Company by Parent or Merger Subsidiary in writing specifically for use therein.

Each International Plan has been maintained in substantial compliance with its terms and with the requirements prescribed by any and all applicable statutes, orders, rules and regulations (including any special provisions relating to qualified plans where such Plan was intended so to qualify) and has been maintained in good standing with applicable regulatory authorities. There has been no amendment to, written interpretation of or announcement (whether or not written) by the Company or any of its Subsidiaries relating to, or change in employee participation or coverage under, any International Plan that would increase materially the expense of maintaining such International Plan above the level of expense incurred in respect thereof for the most recent fiscal year ended prior to the date hereof. According to the actuarial assumptions and valuations most recently used for the purpose of funding each International Plan (or, if the same has no such assumptions and valuations or is unfunded, according to actuarial assumptions and valuations in use by the PBGC on the date hereof), as of February 21, 2006, the total amount or value of the funds available under such Plan to pay benefits accrued thereunder or segregated in respect of such accrued benefits, together with any reserve or accrual with respect thereto, exceeded the present value of all benefits (actual or contingent) accrued as of such date of all participants and past participants therein in respect of which the Company or any of its Subsidiaries has or would have after the Effective Time any obligation. From and after the Effective Time, Parent and its Affiliates will get the full benefit of any such funds, accruals or reserves.

     (ii) the Company and its Subsidiaries are and have been in compliance with all Environmental Laws and all Environmental Permits; and

absolute, determined, determinable or otherwise arising under or relating to any Environmental Law or any Hazardous Substance.
     (b) There has been no environmental investigation, study, audit, test, review or other analysis conducted in the past five years of which the Company has Knowledge in relation to the current or prior business of the Company or any of its Subsidiaries or any property or facility now or previously owned by the Company or any of its Subsidiaries that has not been delivered to Parent at least five Business Days prior to the date hereof.
     (c) Neither the Company nor any of its Subsidiaries owns, leases or operates or has, within the past five years, owned, leased or operated any real property in New Jersey or Connecticut.

     Section 4.24. Antitakeover Statutes. The Company has taken all action necessary to exempt the Merger, this Agreement and the transactions contemplated hereby from Massachusetts General Laws Chapter 110D. Neither Massachusetts General Laws Chapters 110D or 110F nor any other antitakeover or similar statute or regulation applies or purports to apply to any such transactions; provided, however, that, for purposes hereof, Parent and Merger Subsidiary hereby specifically represent and warrant to the Company that neither of them is an “interested stockholder” in the Company, as such term is defined in Massachusetts General Laws Chapter 110F.

     (b) Notwithstanding the foregoing, prior to receiving the Company Stockholder Approval, the Board of Directors of the Company, directly or indirectly through advisors, agents or other intermediaries, may (i) engage in negotiations or discussions with any Third Party (or with the representatives of any Third Party) that, subject to the Company’s compliance with Section 6.03(a)(i), has made a bona fide written Acquisition Proposal that the Board of Directors of the Company reasonably believes will lead to a Superior Proposal, (ii) thereafter furnish to such Third Party nonpublic information relating to the Company or any of its Subsidiaries pursuant to a confidentiality agreement with terms no less favorable to the Company than those contained in the Confidentiality Agreement dated as of September 23, 2005 between the Company and Parent (the “Confidentiality Agreement”); provided, however, that such confidentiality agreement shall not be required to, and shall not, contain any provisions that would prevent the Company from complying with its obligation to provide the required disclosure to Parent pursuant to this Section 6.03 (a copy of which confidentiality agreement shall be provided for informational purposes only to Parent), (iii) following a determination by the Board of Directors of the Company that such Acquisition Proposal is a Superior Proposal, make an Adverse Recommendation Change and/or (iv) take any action that any court of competent jurisdiction orders the Company to take, but in each case referred to in the foregoing clauses (i) through (iii) only if the Board of Directors of the Company determines in good faith by a majority vote, after considering advice from outside legal counsel to the Company (which may be its current outside legal counsel, Sullivan & Worcester LLP), that the failure to take such action would be inconsistent with its fiduciary duties under Applicable Law. Nothing contained herein shall prevent the Board of Directors of the Company from complying with Rule 14e-2(a) or Rule 14d-9 under the 1934 Act with regard to an Acquisition Proposal; provided that the Board of Directors of the Company shall not recommend that the Company’s stockholders tender shares of capital stock in connection with any tender or exchange offer unless the Board of Directors of the Company determines in good faith by a majority vote, after considering advice from outside legal counsel to the Company (which may be its current outside legal counsel, Sullivan & Worcester LLP), that the failure to take such action would be inconsistent with its fiduciary duties under Applicable Law.
     (c) The Board of Directors of the Company shall not take any of the actions referred to in clauses (i) through (iii) or the last sentence of Section 6.03(b) unless the Company shall have delivered to Parent a prior written notice advising Parent that it intends to take such action. In addition, the Company shall notify Parent promptly (but in no event later than 24 hours) after an executive officer or director of the Company first obtains Knowledge of the receipt by the Company (or any of its advisors) of any Acquisition Proposal, any inquiry that

39


 

would reasonably be expected to lead to an Acquisition Proposal or any request for information relating to the Company or any of its Subsidiaries or for access to the business, properties, assets, books or records of the Company or any of its Subsidiaries from any Third Party that a Person acting in good faith would reasonably believe is seeking to make, or has made, an Acquisition Proposal. The Company shall provide such notice orally and in writing and shall identify the Third Party making, and the material terms and conditions of, any such Acquisition Proposal, indication or request. The Company shall keep Parent reasonably informed, on a current basis, of the status and material details of any such Acquisition Proposal, indication or request. The Company shall, and shall cause its Subsidiaries and the advisors, employees and other agents of the Company and any of its Subsidiaries to, cease immediately and cause to be terminated any and all existing activities, discussions or negotiations, if any, with any Third Party conducted prior to the date hereof with respect to any Acquisition Proposal and shall use its reasonable best efforts to cause any such Party (or its agents or advisors) in possession of confidential information about the Company that was furnished by or on behalf of the Company to return or destroy all such information.
     “Superior Proposal” means any bona fide, unsolicited written Acquisition Proposal (with the references to “20% or more” contained therein being replaced with “75% or more”) on terms that the Board of Directors of the Company determines in good faith by a majority vote, after considering the advice of the Company’s financial advisor (which may be RBC Capital Markets Corporation) and taking into account all the terms and conditions of the Acquisition Proposal, including any break-up fees, expense reimbursement provisions and conditions to consummation, are more favorable and provide greater value to all the Company’s stockholders than as provided hereunder and for which financing, if a cash transaction (whether in whole or in part), is then fully committed or reasonably determined to be available by the Board of Directors of the Company.
     Section 6.04. Access to Information. From the date hereof until the Effective Time or the earlier termination of this Agreement, and subject to Applicable Law and the Confidentiality Agreement, the Company shall (i) give to Parent, its counsel, financial advisors, auditors and other authorized representatives reasonable access to the offices, properties, books and records of such party, (ii) furnish to Parent, its counsel, financial advisors, auditors and other authorized representatives such financial and operating data and other information as such Persons may reasonably request and (iii) instruct its employees, counsel, financial advisors, auditors and other authorized representatives to cooperate with Parent in its investigation; provided, however, that the Company shall not be required to provide to Parent or its representatives any of the information specified in Section 6.04 of the Company Disclosure Schedule (or access thereto) until the condition set forth in Section 9.01(c) has been satisfied or waived. Any

40


 

investigation pursuant to this Section shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of the Company. No information or knowledge obtained in any investigation pursuant to this Section shall affect or be deemed to modify any representation or warranty made by any party hereunder. Neither the Company nor any of its Subsidiaries shall be obligated to provide access to, or to disclose, any information to Parent if the Company reasonably determines that such access or disclosure would jeopardize the attorney-client privilege of the Company or any of its Subsidiaries; provided, however, that the parties will at Parent’s request use reasonable efforts to enter into a joint defense or similar agreement that permits access to such information by Parent while preserving the attorney-client privilege of the Company and its Subsidiaries.
     Section 6.05. Tax Matters. (a) From the date of this Agreement until the Effective Time or the earlier termination of this Agreement, neither the Company nor any of its Subsidiaries shall make or change any Tax election, change any annual tax accounting period, adopt or change any method of tax accounting, file any amended Tax Returns or claims for Tax refunds, enter into any closing agreement, settle any Tax claim, audit or assessment, surrender any right to claim a Tax refund, offset or other reduction in Tax liability, consent to any extension or waiver of the limitations period applicable to any Tax claim or assessment or take or omit to take any other action, if any such action or omission would have the effect of materially increasing the Tax liability or materially reducing any Tax asset of the Company or any of its Subsidiaries.
     (b) The Company and each of its Subsidiaries shall establish or cause to be established in accordance with GAAP on or before the Effective Time an adequate accrual for all Taxes due with respect to any period or portion thereof ending prior to or as of the Effective Time.

     (d) The rights of each Indemnified Person under this Section 7.03 shall be in addition to any rights such Person may have under the articles of organization or bylaws of the Company or any of its Subsidiaries, or under Massachusetts Law or any other Applicable Law or under any agreement of any Indemnified Person with the Company or any of its Subsidiaries. These rights shall survive consummation of the Merger and are intended to benefit, and shall be enforceable by, each Indemnified Person.
     (e) The Surviving Corporation shall pay all reasonable costs and expenses, including attorneys’ fees, that may be incurred by any indemnified party in enforcing the indemnity and other obligations provided for in this Section 7.03, so long as such indemnified party undertakes in writing to reimburse the Surviving Corporation for such costs and expenses if it is finally determined by a

42


 

court of competent jurisdiction that such indemnified party was not entitled to be indemnified hereunder.

Each such Continuing Employee will receive credit for purposes of eligibility to participate and vesting under Parent’s plans for years of service with the Company (or any of its Subsidiaries) prior to the Effective Time. Subject to any third party insurer’s consent, Parent will cause any and all pre-existing condition limitations, eligibility waiting periods and evidence of insurability requirements under any group health plans of Parent in which such employees and their eligible dependents will participate to be waived (to the extent not applicable under the Company’s Plans) and will provide credit for any co-payments and deductibles prior to the Effective Time but in the plan year which includes the Effective Time for purposes of satisfying any applicable deductible, out-of-pocket or similar requirements under any such plans that may apply for such plan year after the Effective Time.

     (iv) the Company shall have willfully and materially breached its obligations under Sections 6.02 and 6.03; or

51


 

accordance with the terms, and at the times, specified therein; and provided further that (A) the Company shall have provided Parent with written notice of its intent to terminate this Agreement pursuant to this Section 10.01(d)(i) at least three Business Days in advance of such termination, which written notice shall include the most current version of such agreement and a reasonably detailed summary of any other material terms and conditions relating thereto and (B) Parent does not make, within three Business Days of receipt of such written notice, an offer that the Board of Directors of the Company determines, in good faith after consultation with its financial advisors (which may be RBC Capital Markets Corporation) and taking into account all the terms and conditions of such offer (including any break-up fees, expense reimbursement provisions and conditions to consummation), would, if consummated, result in a transaction at least as favorable to the Company’s stockholders as the transaction set forth in the Company’s written notice delivered pursuant to clause (A) above, it being understood that the Company shall not enter into any such binding, definitive agreement during such three Business Day period. The Company agrees to notify Parent promptly if its intention to enter into any such agreement referred to in Section 10.01(d)(i)(A) shall change at any time after giving such notification; or
     (ii) a breach of any representation or warranty or failure to perform any covenant or agreement on the part of Parent or Merger Subsidiary set forth in this Agreement shall have occurred that would cause the condition set forth in Section 9.03(a) not to be satisfied, and such condition is incapable of being satisfied by the End Date.

If this Agreement is terminated pursuant to Section 10.01, this Agreement shall become void and of no effect without liability of any party (or any stockholder, director, officer, employee, agent, consultant or representative of such party) to the other party hereto; provided that, if such termination shall result from the willful (i) failure of either party to fulfill a condition to the performance of the obligations of the other party or (ii) failure of either party to perform a covenant hereof, such party shall be fully liable for any and all liabilities and damages incurred or suffered by the other party as a result of such failure.

VOTING AGREEMENT
     AGREEMENT, dated as of February 22, 2006 between KLA-Tencor Corporation, a Delaware corporation (“Parent”), and                 (“Stockholder”), a stockholder in ADE Corporation, a Massachusetts corporation (the “Company”).
     WHEREAS, in order to induce Parent and Merger Subsidiary to enter into an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”; capitalized terms used but not defined herein shall have the respective meanings set forth in the Merger Agreement) with the Company, Parent has requested Stockholder, and Stockholder has agreed, to enter into this Agreement with respect to all shares of common stock, par value $0.01 per share, of the Company that Stockholder beneficially owns (the “Shares”).
     NOW, THEREFORE, the parties hereto agree as follows:
ARTICLE 1
Grant of Proxy; Voting Agreement
     Section 1.01. Voting Agreement. Stockholder hereby agrees to vote or exercise its right to consent with respect to all Shares that Stockholder is entitled to vote at the time of any vote or action by written consent to approve and adopt the Merger Agreement and the Merger at any meeting of the stockholders of the Company, and at any adjournment or postponement thereof, at which such Merger Agreement (or any amended version thereof) is submitted for the consideration and vote of the stockholders of the Company. Stockholder hereby agrees that it will not vote any Shares in favor of, or consent to, and will vote against and not consent to, the approval of any (i) Acquisition Proposal, (ii) reorganization, recapitalization, liquidation or winding-up of the Company or any other extraordinary transaction involving the Company or (iii) corporate action the consummation of which would frustrate the purposes, or prevent or delay the consummation, of the transactions contemplated by the Merger Agreement.
     Section 1.02. Irrevocable Proxy. Stockholder hereby revokes any and all previous proxies granted with respect to the Shares. By entering into this Agreement, Stockholder hereby grants a proxy appointing Parent as the Stockholder’s attorney-in-fact and proxy, with full power of substitution, for and in the Stockholder’s name, to vote, express consent or dissent, or otherwise to utilize such voting power in the manner contemplated by Section 1.01 above as Parent or its proxy or substitute shall, in Parent’s sole discretion, deem proper with respect to the Shares. The proxy granted by Stockholder pursuant to this Article 1 is irrevocable and is granted in consideration of Parent entering into this

 


 

Agreement and the Merger Agreement and incurring certain related fees and expenses; provided, however, that the proxy granted by Stockholder shall be revoked upon termination of this Agreement in accordance with its terms.

     C. The undersigned has been advised that the issuance of Parent Common Stock to the undersigned pursuant to the Merger will be registered with the SEC under the 1933 Act on a Registration Statement on Form S-4. The undersigned has also been advised that, because, at the time the Merger is submitted for a vote of the shareholders of the Company, the undersigned may be deemed an affiliate of the Company, the undersigned may not sell, transfer or otherwise dispose of Parent Common Stock issued to the undersigned in the Merger unless such sale, transfer or other disposition (i) has been registered under the 1933 Act, (ii) is made in conformity with Rule 145 promulgated by the SEC under the 1933 Act, or (iii) in the opinion of counsel reasonably acceptable to Parent, or pursuant to a “no action” letter obtained by the undersigned from the SEC staff, is otherwise exempt from registration under the 1933 Act.
     D. The undersigned understands that Parent is under no obligation to register the sale, transfer or other disposition of Parent Common Stock acquired in the Merger by the undersigned or on the undersigned’s behalf under the 1933 Act or to take any other action necessary in order to enable the undersigned to make such sale, transfer or other disposition in compliance with an exemption from such registration.

Boston, Massachusetts 02109
Ladies and Gentlemen:
     This letter is being delivered in connection with the opinions to be delivered pursuant to Sections 9.02(c) and 9.03(b) of the Agreement and Plan of Merger (the “Merger Agreement”)1, dated as of February 22, 2006, among KLA-Tencor Corporation, a Delaware corporation (“Parent”), ADE Corporation, a Massachusetts corporation (the “Company”), and South Acquisition Corporation, a Delaware corporation and a direct wholly-owned subsidiary of Parent (“MergerSub”), pursuant to which MergerSub shall be merged with and into the Company, the separate corporate existence of MergerSub shall cease, and the Company shall continue as the surviving corporation (the “Merger”). The undersigned officer of each of Parent and Merger Sub, on behalf of Parent and Merger Sub, hereby certifies and represents that the statements and representations herein are true, correct and complete at the date hereof and will be true, correct and complete at the Effective Time:
     1. Parent’s and Merger Sub’s principal reasons for participating in the Merger are bona fide business purposes not related to taxes.
     2. The consideration to be received in the Merger by holders of Company Common Stock was determined by arm’s length negotiations between the managements of Parent and the Company. In connection with the Merger, no holder of Company Common Stock will receive in exchange for such stock, directly or indirectly, any consideration other than Parent Common Stock and cash in lieu of fractional shares of Parent Common Stock.
     3. The fair market value of the Parent Common Stock and cash in lieu of fractional shares of Parent Common Stock received by each holder of
 
     1 All defined terms used herein and not otherwise defined have the meanings ascribed to them in the Merger Agreement.

 


 

Company Common Stock will be approximately equal to the fair market value of the Company Common Stock surrendered in exchange therefor.
     4. The Parent Common Stock for which Company Common Stock will be exchanged in the Merger will be entitled to vote in the election of directors of Parent and on all other matters put forth to the stockholders of Parent.
     5. Pursuant to the Merger, as of the Effective Time, shares of Company Common Stock representing control of the Company will be exchanged solely for voting stock of Parent.2 For purposes of this representation, shares of Company Common Stock redeemed or disposed of pursuant to the exercise of dissenters’ rights under applicable laws or exchanged for cash or other property furnished, directly or indirectly, by Parent or any affiliate of Parent shall be treated as outstanding Company Common Stock at the Effective Time.
     6. To the best knowledge of the management of Parent, at the Effective Time, the Company will not have outstanding any warrants, options, convertible securities, or any other type of rights pursuant to which any Person could acquire stock in the Company that, if exercised or converted, would affect Parent’s acquisition or retention of control of the Company.
     7. Parent has no plan or intention to cause or permit the Company, after the Effective Time, to issue additional shares of stock (or securities, options, warrants or instruments giving the holder thereof the right to acquire Company Common Stock) that would (or if exercised would) result in Parent losing control of the Company.
     8. The payment of cash in lieu of fractional shares of Parent Common Stock to holders of Company Common Stock is solely for the purpose of avoiding the expense and inconvenience to Parent of issuing fractional shares and does not represent separately bargained for consideration. The total amount of cash that will be paid to holders of Company Common Stock instead of issuing fractional shares of Parent Common Stock will not exceed one percent of the total consideration that will be issued in the Merger to holders of Company Common Stock in exchange for shares of Company Common Stock. The fractional share interests of each holder of Company Common Stock will be aggregated, and no holder of Company Common Stock will receive cash in lieu of fractional shares in an amount equal to or greater than the value of one full share of Parent Common Stock, except for any cases in which a holder of Company Common Stock holds beneficial interests in shares of the Company through more than one account and such multiple accounts cannot be aggregated, either because the beneficial interest
 
     2 For purposes of this representation letter, “control” with respect to a corporation shall mean ownership of at least (i) 80 percent of the total combined voting power of all classes of stock entitled to vote and (ii) 80 percent of the total number of shares of each other class of stock of the corporation.

2


 

cannot be identified or it would be improper or impracticable to do so, and in any cases in which the same stockholder owns stock in multiple accounts and Parent cannot aggregate those accounts through use of their common taxpayer identification number or EIN or otherwise (in which case no account will receive more than a fraction of one share in cash).
     9. Neither Parent nor any affiliate of Parent has any plan or intention, directly or indirectly, to redeem, purchase, exchange or otherwise reacquire (including by derivative transactions such as an equity swap which would have the economic effect of an acquisition) any of the Parent Common Stock to be issued in the Merger, other than possible repurchases of unvested shares of employees or consultants in connection with terminations of services or stock repurchases pursuant to a stock repurchase plan adopted prior to the date of the Merger Agreement by Parent (i) made in the open market for stock of the Parent which is widely held and publicly traded (except that Parent may acquire stock in block trades made directly with an entity that has represented to Parent that such entity did not acquire such stock in the Merger) and (ii) limited to, in the aggregate, the number of shares of Parent Common Stock issued and outstanding prior to the Effective Time.
     10. After the Merger, no dividends or distributions will be made to the former holders of Company Common Stock by Parent other than dividends or distributions made to all holders of Parent Common Stock.
     11. As of the Effective Time, neither Parent nor any affiliate of Parent will own beneficially or of record, or, will have owned beneficially or of record during the five years preceding the Effective Time, any shares of Company Common Stock or other securities, options, warrants or instruments giving the holder thereof the right to acquire Company Common Stock or other securities issued by the Company.
     12. Prior to the Merger, Parent will be in control of MergerSub. Parent has no plan or intention to cause MergerSub to, and MergerSub has no plan or intention to, issue additional shares of its stock that would result in Parent not being in control of MergerSub at the Effective Time.
     13. MergerSub is being formed solely to effect the Merger and it will not conduct any business or other activities prior to the Merger. MergerSub will have no liabilities that will be assumed by the Company in the Merger and it will not transfer any assets to the Company in the Merger that are subject to any liabilities.
     14. Immediately after the Effective Time, to the best knowledge of the management of Parent and MergerSub, the Company will hold at least 90% of the fair market value of its net assets and at least 70% of the fair market value of its gross assets and the Company will hold at least 90% of the fair market value of MergerSub’s net assets and at least 70% of the fair market value of MergerSub’s

3


 

gross assets held immediately prior to the Effective Time. For purposes of this representation, amounts paid or incurred by the Company in connection with the Merger, including amounts used (or to be used) by the Company to pay Merger expenses, amounts paid (or to be paid) by the Company to holders of Company Common Stock pursuant to the exercise of dissenters’ rights under applicable laws, amounts paid by the Company to stockholders who receive cash or other property, amounts paid (or to be paid) by the Company to redeem stock, securities, warrants or options of the Company, or to repay any indebtedness of the Company, as part of any overall plan of which the Merger is a part and amounts distributed (or to be distributed) by the Company to stockholders of the Company (except for regular, normal dividends) as part of any overall plan of which the Merger is a part, will be treated as constituting assets of the Company immediately prior to the Effective Time.
     15. Following the Merger, Parent will continue the conduct of the Company’s historic business or use a significant portion of the Company’s historic business assets in a business. For this purpose, Parent will be treated as holding all of the businesses and assets of its Qualified Group. If Parent’s Qualified Group owns an interest in a partnership, Parent will be treated as owning a proportionate share of the Company business assets used in a business of that Partnership. Parent will be treated as conducting a business of any partnership in which members of Parent’s Qualified Group own a significant interest and have active and substantial management functions as a partner with respect to that partnership business. As defined in Treasury Regulation Section 1.368-1(d)(iii), a Qualified Group is one or more chains of corporations connected through stock ownership with Parent but only if Parent is in control of at least one other corporation and each of the corporations (other than Parent) is controlled directly by one of the other corporations.
     16. Parent has no plan or intention following the Merger to (i) liquidate the Company, (ii) merge the Company with or into another entity, (iii) sell, exchange, distribute or otherwise dispose of the stock of the Company, except for transfers (including successive transfers) of such stock to one or more corporations controlled by the transferor corporation at the time of such transfer or (iv) permit or cause the Company to sell, exchange or otherwise dispose of any of its assets, or any of the assets it acquires from MergerSub, except for dispositions in the ordinary course of its business or transfers (including successive transfers) of assets to one or more corporations controlled, in the case of each transfer, by the transferor corporation.
     17. Parent and MergerSub each will pay its or their own expenses, if any, incurred in connection with or as part of the Merger or related transactions. Neither Parent nor MergerSub has paid or will pay, directly or indirectly, any expenses (including transfer taxes) incurred by any holder of Company Common Stock in connection with or as part of the Merger or any related transactions. Neither Parent nor MergerSub has agreed to assume, nor will it directly or indirectly assume, any other expense or other liability, whether fixed or

contingent, of any holder of Company Common Stock, nor will Parent acquire in the Merger any Company Common Stock subject to any liabilities.
     18. There is no intercorporate indebtedness existing between Parent or any of its subsidiaries, on the one hand, and the Company or any of its subsidiaries, on the other hand.
     19. Neither Parent nor MergerSub is a regulated investment company within the meaning of Section 851 of the Code, a real estate investment trust within the meaning of Section 856 of the Code or a corporation fifty percent (50%) or more of the value of whose assets are stock and securities and eighty percent (80%) or more of the value of whose total assets are assets held for investment (each, an “Investment Company”). For purposes of this representation, in making the 50% and 80% determinations under the preceding sentence, (i) stock and securities in any subsidiary corporation shall be disregarded and the parent corporation shall be deemed to own its ratable share of the subsidiary’s assets and (ii) a corporation shall be considered a subsidiary if the parent owns 50% or more of the combined voting power of all classes of stock entitled to vote or 50% or more of the total value of shares of all classes of stock outstanding. In determining total assets there shall be excluded cash and cash items (including receivables), government securities and assets acquired (through incurring indebtedness or otherwise) for purposes of ceasing to be an Investment Company.
     20. None of the compensation received or to be received by any employees or independent contractors of the Company is or will be separate consideration for or allocable to, any of their shares of Company Common Stock to be surrendered in the Merger. None of the shares of Parent Common Stock to be received by any employee or independent contractor of the Company in the Merger is or will be separate consideration for, or allocable to, any employment, consulting or similar arrangement. Any compensation paid or to be paid to any stockholder of the Company who will be an employee of or perform services for Parent, the Company or any affiliate thereof after the Merger, will be determined by bargaining at arm’s length.
     21. The Merger will be carried out in accordance with the Merger Agreement, and as described in the Proxy Statement/Prospectus, and none of the material terms and conditions therein has been or will be waived or modified.
     22. There are no agreements regarding the Merger other than those expressly referred to in the Merger Agreement.
     23. Neither Parent nor MergerSub will take any position on any federal, state, or local income or franchise tax return, or take any other tax reporting position, that is inconsistent with the treatment of the Merger as a reorganization within the meaning of Section 368(a) of the Code or with any of the foregoing representations.

     3. The fair market value of the Parent Common Stock and cash in lieu of fractional shares of Parent Common Stock received by each holder of Company Common Stock will be approximately equal to the fair market value of the Company Common Stock surrendered in exchange therefor.
     4. Pursuant to the Merger, as of the Effective Time, shares of Company Common Stock representing control of the Company will be exchanged solely for voting stock of Parent. For purposes of this representation letter, “control” with respect to a corporation shall mean ownership of at least (i) 80 percent of the total combined voting power of all classes of stock entitled to vote and (ii) 80 percent of the total number of shares of each other class of stock of the corporation. For purposes of this representation, shares of Company Common Stock redeemed or disposed of pursuant to the exercise of dissenters’ rights under applicable laws or exchanged for cash or other property furnished, directly or indirectly, by Parent or any affiliate of Parent shall be treated as outstanding Company Common Stock at the Effective Time.
     5. At the Effective Time, the Company will not have outstanding any warrants, options, convertible securities, or any other type of rights pursuant to which any Person could acquire stock in the Company that, if exercised or converted, would affect Parent’s acquisition or retention of control of the Company.
     6. The Company has no plan or intention to issue additional shares of stock (or securities, options, warrants or instruments giving the holder thereof the right to acquire Company Common Stock) after the Effective Time that would (or if exercised would) result in Parent losing control of the Company.

to redeem, purchase, exchange or otherwise reacquire (including by derivative transactions such as an equity swap which would have the economic effect of an acquisition) any of the Parent Common Stock to be issued in the Merger, other than possible repurchases of unvested shares of employees or consultants in connection with terminations of services or stock repurchases pursuant to a stock repurchase plan adopted prior to the date of the Merger Agreement by Parent (i) made in the open market for stock of the Parent which is widely held and publicly traded (except that Parent may acquire stock in block trades made directly with an entity that has represented to Parent that such entity did not acquire such stock in the Merger) and (ii) limited to, in the aggregate, the number of shares of Parent Common Stock issued and outstanding prior to the Effective Time.

Following the Merger, to the best knowledge of the management of the Company, Parent will continue the conduct of the Company’s historic business or use a significant portion of the Company’s historic business assets in a business. For this purpose, Parent will be treated as holding all of the businesses and assets of its Qualified Group. If Parent’s Qualified Group owns an interest in a partnership, Parent will be treated as owning a proportionate share of the Company business assets used in a business of that Partnership. Parent will be treated as conducting a business of any partnership in which members of Parent’s Qualified Group own a significant interest and have active and substantial management functions as a partner with respect to that partnership business. As defined in Treasury Regulation Section 1.368-1(d)(iii), a Qualified Group is one or more chains of corporations connected through stock ownership with Parent but only if Parent is in control of at least one other corporation and each of the corporations (other than Parent) is controlled directly by one of the other corporations.
     14. Except as may be provided in the voting agreements (in form attached as Exhibit A to the Merger Agreement), the Company and the holders of Company Common Stock each will pay its or their own expenses, if any, incurred in connection with or as part of the Merger or related transactions. Except as may be provided in the voting agreements (in form attached as Exhibit A to the Merger Agreement), the Company has not agreed to pay or assume, nor will it directly or indirectly assume, any expense or other liability, whether fixed or contingent, of any holder of Company Common Stock in connection with or as part of the Merger or any related transactions. Except as may be provided in the voting agreements (in form attached as Exhibit A to the Merger Agreement), no liabilities of the Company or, to the best knowledge of the management of the Company, the Company stockholders will be assumed by Parent, and, to the best knowledge of the management of the Company, Parent will not acquire in the Merger any Company Common Stock subject to any liabilities.
     15. There is no intercorporate indebtedness existing between Parent or any of its subsidiaries, on the one hand, and the Company or any of its subsidiaries, on the other hand.
     16. At the Effective Time, the fair market value of the assets of the Company will equal or exceed the sum of its liabilities, plus (without duplication) the amount of liabilities, if any, to which the Company’s assets are subject.
     17. The Company is not a regulated investment company within the meaning of Section 851 of the Code, a real estate investment trust within the meaning of Section 856 of the Code, or a corporation fifty percent (50%) or more of the value of whose assets are stock and securities and eighty percent (80%) or more of the value of whose total assets are assets held for investment (each, an

For purposes of this representation, in making the 50% and 80% determinations under the preceding sentence, (i) stock and securities in any subsidiary corporation shall be disregarded and the parent corporation shall be deemed to own its ratable share of the subsidiary’s assets, and (ii) a corporation shall be considered a subsidiary if the parent owns 50% or more of the combined voting power of all classes of stock entitled to vote or 50% or more of the total value of shares of all classes of stock outstanding. In determining total assets there shall be excluded cash and cash items (including receivables), government securities, and assets acquired (through incurring indebtedness or otherwise) for purposes of ceasing to be an Investment Company.
