AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”) is entered into as of March 22, 2007, by and among Seahawk Acquisition Corporation, a Delaware corporation (the “Buyer”), Seahawk Merger Sub Corporation, a Massachusetts corporation and a wholly-owned subsidiary of the Buyer (the “Transitory Subsidiary”), and Kronos Incorporated, a Massachusetts corporation (the “Company”).

WHEREAS, a non-management member committee of the Company Board has (i) determined that the Merger on the terms and subject to the conditions set forth in this Agreement is advisable and in the best interests of the Company’s shareholders, and (ii) approved this Agreement and recommended adoption of this Agreement by the Company Board;

WHEREAS, the respective Boards of Directors of the Buyer and the Company deem it advisable and in the best interests of each corporation and their respective shareholders that the Buyer acquire the Company in order to advance the long-term business interests of the Buyer and the Company;

WHEREAS, the acquisition of the Company shall be effected through a merger (the “Merger”) of the Transitory Subsidiary with and into the Company in accordance with the terms of this Agreement and the Massachusetts Business Corporation Act (the “MBCA”), as a result of which the Company shall become a wholly-owned subsidiary of the Buyer;

WHEREAS, the respective Boards of Directors of the Buyer, the Transitory Subsidiary and the Company deem it advisable and in the best interests of their respective shareholders to consummate the Merger on the terms and conditions set forth in this Agreement; and

WHEREAS, simultaneously with the execution of this Agreement, and as a condition and inducement to the Company’s willingness to enter into this Agreement, the Buyer has delivered to the Company duly executed guarantees of Hellman & Friedman Capital Partners VI, L.P. and JMI Equity Fund V, L.P. (the “Guarantors”) in the form attached as Annex I to this Agreement (the “Guarantees”), pursuant to which, and subject to the terms and conditions thereof, the Guarantors have guaranteed certain obligations of the Buyer hereunder.

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 Buyer, the Transitory Subsidiary and the Company agree as follows:

The Merger shall become effective upon the filing of the Articles of Merger with the Secretary of State of the Commonwealth of Massachusetts or at such later time as is established by the Buyer and the Company and set forth in the Articles of Merger (the “Effective Time”).

1.2Closing. 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 Buyer 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 Wilmer Cutler Pickering Hale and Dorr LLP, 60 State Street, Boston, Massachusetts, unless another date, place or time is agreed to in writing by the Buyer and the Company. For purposes of this Agreement, a “Business Day” shall be any day other than (a) a Saturday or Sunday or (b) a day on which banking institutions located in New York, New York are permitted or required by law, executive order or governmental decree to remain closed.

1.3Effects of the Merger. At the Effective Time, the separate existence of the Transitory Subsidiary shall cease and the Transitory Subsidiary shall be merged with and into the Company (the Company surviving the Merger is sometimes referred to herein as the “Surviving Corporation”). The Merger shall have the effects set forth in Section 11.07 of the MBCA.

1.4Articles of Organization. At the Effective Time, the Articles of Organization of the Company, as in effect immediately prior to the Effective Time, shall be amended to read in their entirety as set forth inExhibit A attached hereto and, as so amended, shall be the Articles of Organization of the Surviving Corporation until thereafter amended in accordance with the provisions thereof and as provided by applicable law.

1.5By-laws. At the Effective Time, the By-laws of the Company, as in effect immediately prior to the Effective Time, shall be amended and restated to read in their entirety as set forth inExhibit B attached hereto and, as so amended and restated, shall be the By-laws of the Surviving Corporation until thereafter amended as provided by applicable law, the Articles of Organization of the Surviving Corporation and such By-laws.

1.6Directors and Officers of the Surviving Corporation.

(a) The directors of the Transitory Subsidiary immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation, each to hold office in accordance with the Articles of Organization and By-laws of the Surviving Corporation.

(b) The officers of the Company immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation, each to hold office in accordance with the Articles of Organization and By-laws of the Surviving Corporation.

ARTICLE II

CONVERSION OF SECURITIES

2.1Conversion 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, par value $0.01 per share, 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, $0.01 par value per share, of the Surviving Corporation.

(b)Cancellation of Treasury Stock and Buyer-Owned Stock. All shares of common stock, $0.01 par value per share, of the Company (“Company Common Stock”) that are owned by the Company as treasury stock and any shares of Company Common Stock owned by the Buyer, the Transitory Subsidiary or any other wholly-owned Subsidiary of the Buyer immediately prior to the Effective Time shall be cancelled and shall cease to exist and no stock of the Buyer or other consideration shall be delivered in exchange therefor.

(c)Merger Consideration 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), any shares of Company

Common Stock that are owned by a wholly-owned Subsidiary of the Company, which shall remain outstanding, and Dissenting Shares (as defined in Section 2.5(a) below)) issued and outstanding immediately prior to the Effective Time shall be automatically converted into the right to receive $55.00 in cash per share, without interest (the “Merger Consideration”). 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 Merger Consideration pursuant to this Section 2.1(c) upon the surrender of such certificate in accordance with Section 2.2, without interest.

(d)Adjustments to Merger Consideration. The Merger Consideration shall be adjusted to reflect fully the effect of any reclassification, stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), reorganization, recapitalization or other like change with respect to Company Common Stock occurring (or for which a record date is established) after the date hereof and prior to the Effective Time.

2.2Exchange of Certificates. The procedures for exchanging certificates representing shares of Company Common Stock for the Merger Consideration pursuant to the Merger are as follows:

(a)Exchange Agent. At or prior to the Effective Time, the Buyer shall deposit with a bank or trust company mutually acceptable to the Buyer and the Company (the “Exchange Agent”), for the benefit of the holders of shares of Company Common Stock outstanding immediately prior to the Effective Time, for payment through the Exchange Agent in accordance with this Section 2.2, cash in an amount sufficient to make payment of the Merger Consideration pursuant to Section 2.1(c) in exchange for all of the outstanding shares of Company Common Stock (the “Exchange Fund”).

(b)Exchange Procedures. Promptly (and in any event within five Business Days) after the Effective Time, the Buyer shall cause the Exchange Agent to mail to each holder of record of a certificate which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (each, a “Certificate”) (i) a letter of transmittal in customary form and (ii) instructions for effecting the surrender of the Certificates in exchange for the Merger Consideration payable with respect thereto. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration that such holder has the right to receive pursuant to the provisions of this Article II, 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, the Merger Consideration may be 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 Merger Consideration as contemplated by this Section 2.2.

(c)No Further Ownership Rights in Company Common Stock. All Merger Consideration paid upon the surrender for exchange of Certificates evidencing shares of Company Common Stock in accordance with the terms hereof shall be deemed to have been paid in 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.

(d)Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Company Common Stock for one year after the Effective Time shall be delivered to the

Buyer, upon demand, and any holder of Company Common Stock who has not previously complied with this Section 2.2 shall be entitled to receive only from the Buyer payment of its claim for Merger Consideration.

(e)No Liability. To the extent permitted by applicable law, none of the Buyer, the Transitory Subsidiary, the Company, the Surviving Corporation or the Exchange Agent shall be liable to any holder of shares of Company Common Stock delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(f)Withholding Rights. Each of the Buyer and the Surviving Corporation shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), or any other applicable state, local or foreign tax law. To the extent that amounts are so withheld by the Surviving Corporation or the Buyer, as the case may be, such withheld amounts (i) shall be remitted by the Buyer or the Surviving Corporation, as the case may be, to the applicable Governmental Entity, and (ii) 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 Surviving Corporation or the Buyer, as the case may be.

(g)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 the posting by such person of a bond in a customary amount 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 Merger Consideration deliverable in respect thereof pursuant to this Agreement.

(h)Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of shares thereafter on the records of the Company. From and after the Effective Time, the holders of Certificates representing shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares, except as otherwise provided in this Agreement or by applicable law. On or after the Effective Time, any Certificates presented to the Exchange Agent or the Buyer for any reason shall be canceled against delivery of the Merger Consideration to which the holders thereof are entitled pursuant to Section 2.1(c).

2.3Company Stock Plans.

(a) Subject to Section 2.3(b), the Company shall take such action as shall be required:

(i) to cause the vesting of any unvested options to purchase Company Common Stock (“Company Stock Options”) granted under any stock option plans or other equity-related plans of the Company (the “Company Stock Plans”) to be accelerated in full effective immediately prior to the Effective Time;

(ii) to effectuate the cancellation, as of the Effective Time, of all Company Stock Options outstanding immediately prior to the Effective Time (without regard to the exercise price of such Company Stock Options); and

(iii) to cause, pursuant to the Company Stock Plans, each outstanding Company Stock Option to represent as of the Effective Time solely the right to receive, in accordance with this Section 2.3, a lump sum cash payment in the amount of the Option Consideration (as defined below), if any, with respect to such Company Stock Option and to no longer represent the right to purchase Company Common Stock or any other equity security of the Company, the Buyer, the Surviving Corporation or any other person or any other consideration.

(b) Except as otherwise agreed by the Buyer and any holder of a Company Stock Option, each holder of a Company Stock Option shall be entitled to receive from the Surviving Corporation, in respect and in

consideration of each Company Stock Option so cancelled, as soon as practicable following the Effective Time (but in any event not later than five Business Days), an amount, if any (net of applicable taxes) equal to the product of (i) the excess, if any, of (A) the Merger Consideration per share of Company Common Stock over (B) the exercise price per share of Company Common Stock subject to such Company Stock Option, multiplied by (ii) the total number of shares of Company Common Stock subject to such Company Stock Option (whether or not then vested or exercisable), without any interest thereon (the “Option Consideration”). In the event that the exercise price of any Company Stock Option is equal to or greater than the Merger Consideration, such Company Stock Option shall be cancelled and have no further force or effect without payment of any consideration in respect thereof.

(c) As soon as practicable following the execution of this Agreement, the Company shall mail to each person who is a holder of Company Stock Options a letter describing the treatment of and payment for such Company Stock Options pursuant to this Section 2.3 and providing instructions for use in obtaining payment for such Company Stock Options. The Buyer shall at all times from and after the Effective Time cause the Surviving Corporation to maintain sufficient liquid funds to satisfy its obligations to holders of Company Stock Options pursuant to this Section 2.3.

(d) The Company shall (i) terminate its 2003 Employee Stock Purchase Plan, as amended (the “Company ESPP”), in accordance with its terms as of or prior to the Effective Time and (ii) take such action as shall be required to suspend the current offering period under the Company ESPP and provide that no further offering period or purchase period shall commence under the Company ESPP at any time after the date of this Agreement (with respect to persons participating in the Company ESPP on the date hereof (and who have not withdrawn from or otherwise ceased participation therein prior to such date), accumulated contributions will be applied on such date to the purchase of Company Common Stock in accordance with the Company ESPP’s terms and any remaining balances in the withholding accounts of the participants in the Company ESPP will be returned in accordance with the terms of the Company ESPP).

2.4Restricted Shares; RSUs.

(a) As of the Effective Time, except as otherwise agreed by Buyer and any holder of an award of shares of Company Common Stock pursuant to a Company Stock Plan that is subject to vesting or other lapse restrictions (“Restricted Shares”), with respect to each such holder’s Restricted Shares, each award of Restricted Shares which is outstanding immediately prior to the Effective Time shall vest in full and become free of applicable lapse restrictions as of the Effective Time and shall, as of the Effective Time, be canceled and converted into the right to receive from the Surviving Corporation the Merger Consideration in accordance with Section 2.1(c).

(b) As of the Effective Time, except as otherwise agreed by Buyer and any holder of an award of a right to shares of Company Common Stock pursuant to a Company Stock Plan that is subject to vesting or other lapse restrictions (“RSUs”), with respect to each such holder’s RSUs, each award of RSUs which is outstanding immediately prior to the Effective Time shall vest in full and become free of applicable lapse restrictions as of the Effective Time and shall, as of the Effective Time, be canceled and extinguished, and the holder thereof shall be entitled to receive from the Surviving Corporation an amount in cash equal to (i) the product of (A) the number of shares previously subject to such RSU and (B) the Merger Consideration, and (ii) the value of any deemed dividend equivalents accrued but unpaid with respect to such RSUs, less any amounts required to be withheld under any applicable law. All payments with respect to canceled RSUs shall be made by the Surviving Corporation (or such other agent as the Surviving Corporation shall designate, which may be the Surviving Corporation’s payroll agent) as promptly as reasonably practicable after the Effective Time from funds deposited by or at the direction of the Surviving Corporation to pay such amounts.

2.5Dissenting Shares.

(a) Notwithstanding anything to the contrary contained in this Agreement, shares of Company Common Stock held by a holder who is entitled to demand and has made a demand for appraisal of such

shares of Company Common Stock in accordance with the MBCA and has not voted in favor of the approval of this Agreement (any such shares being referred to as “Dissenting Shares” until such time as such holder fails to perfect or otherwise loses such holder’s appraisal rights under the MBCA with respect to such shares) shall not be converted into or represent the right to receive Merger Consideration in accordance with Section 2.1, but shall be entitled only to such rights as are granted by the MBCA to a holder of Dissenting Shares.

(b) If any Dissenting Shares shall lose their status as such (through failure to perfect or otherwise), then, as of the later of the Effective Time or the date of loss of such status, such shares shall automatically be converted into and shall represent only the right to receive Merger Consideration in accordance with Section 2.1, without interest thereon, upon surrender of the Certificates representing such shares.

(c) The Company shall give the Buyer: (i) prompt notice of any written demand for appraisal received by the Company prior to the Effective Time pursuant to the MBCA, any withdrawal of any such demand and any other demand, notice or instrument delivered to the Company prior to the Effective Time pursuant to the MBCA that relate to such demand; and (ii) the opportunity to participate in all negotiations and proceedings with respect to any such demand, notice or instrument. The Company shall not make any payment or settlement offer prior to the Effective Time with respect to any such demand, notice or instrument unless the Buyer shall have given its written consent to such payment or settlement offer.

The Company represents and warrants to the Buyer and the Transitory Subsidiary that the statements contained in this Article III are true and correct, except as set forth in the disclosure schedule delivered by the Company to the Buyer and the Transitory Subsidiary and dated as of the date of this Agreement (the “Company Disclosure Schedule”). The Company Disclosure Schedule shall be arranged in sections and paragraphs corresponding to the numbered and lettered sections and paragraphs contained in this Article III, and the disclosure in any Section or paragraph shall qualify (a) the corresponding Section or paragraph in this Article III and (b) the other sections and paragraphs in this Article III to the extent that it is reasonably apparent from a reading of such disclosure that it also qualifies or applies to such other sections and paragraphs.

3.1Organization, Standing and Power. The Company is a corporation duly organized, validly existing and 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 is duly qualified to do business and, where applicable as a legal concept, 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 qualified or in good standing, individually or in the aggregate, that are not reasonably likely to have a Company Material Adverse Effect. For purposes of this Agreement, the term “Company Material Adverse Effect” means (i) any changes, effects, events or circumstances that are, individually or in the aggregate, materially adverse to the business, assets, condition (financial or otherwise) or results of operations of the Company and its Subsidiaries, taken as a whole; provided, however, that none of the following shall constitute, or shall be considered in determining whether there has occurred, a Company Material Adverse Effect (but, in the case of clauses (a), (b) and (d) below, only to the extent that do not have a disproportionate adverse effect on the Company and its Subsidiaries relative to other participants in the industries or markets in which they operate):

(a) changes that are the result of economic factors affecting the national or world economy or acts of war or terrorism;

(b) changes that are the result of factors generally affecting the industries or markets in which the Company operates;

(c) any adverse change, effect, event or circumstance resulting from the pendency or announcement of the transactions contemplated by this Agreement;

(d) changes in law, rule or regulations or generally accepted accounting principles or the interpretation thereof;

(e) any action taken that is required by this Agreement (other than the consummation of the Merger) or at the written request of the Buyer;

(f) any fees or expenses incurred in connection with the transactions contemplated by this Agreement;

(g) any failure by the Company to meet any published estimates of revenues or earnings for any period ending on or after the date of this Agreement and prior to the Closing (it being understood that any change, effect, event, circumstance or development causing or contributing to such decline may be taken into account in determining whether a Company Material Adverse Effect has occurred);

(h) a decline in the price of the Company Common Stock on The Nasdaq Global Select Market (it being understood that any change, effect, event, circumstance or development causing or contributing to such decline may be taken into account in determining whether a Company Material Adverse Effect has occurred);

(i) any shareholder litigation to the extent arising from or relating to the Merger based on allegations that either the Company’s entry into this Agreement or the terms and conditions of this Agreement constituted a breach of the fiduciary duties of the Company Board or that the disclosures in the Proxy Statement were inadequate; or

(ii) any material adverse change, effect, event, circumstance or development with respect to, or any material adverse effect on, the ability of the Company to consummate the transactions contemplated by this Agreement.

The Buyer shall not, and shall not permit any of its Affiliates to, without the prior written consent of the Company, take any action or enter into any transaction, including any merger, acquisition, joint venture, disposition, lease, contract or debt or equity financing, that would reasonably be expected to impair, delay or prevent the Buyer’s obtaining of the financing contemplated by any Commitment Letter. The Buyer shall not amend or alter, or agree to amend or alter, any Commitment Letter in any manner that would reasonably be expected to impair, delay or prevent the transactions contemplated by this Agreement without the prior written consent of the Company.

(c) If any Commitment Letter shall be terminated or modified in a manner materially adverse to the Buyer for any reason, the Buyer shall use its reasonable best efforts to obtain, and, if obtained, will provide

the Company with a copy of, a new financing commitment that provides for at least the same amount of financing as such Commitment Letter as originally issued; provided that the Buyer shall be under no obligation to obtain or seek to obtain any financing on terms and conditions less favorable, in the aggregate, to the Buyer or the Transitory Subsidiary than those included in the Debt Commitment Letter (as determined in the good faith reasonable discretion of the Buyer).

(d) The Company agrees to provide, and to cause its Subsidiaries and its and their Representatives to provide, the Buyer and the Transitory Subsidiary with such cooperation (including with respect to timeliness) in connection with the arrangement of the financings contemplated by the Debt Commitment Letter as may be reasonably requested by the Buyer or the Transitory Subsidiary, including (i) participation in meetings, drafting sessions, due diligence sessions, management presentation sessions, “road shows” and sessions with rating agencies, (ii) furnishing the Buyer, the Transitory Subsidiary and their financing sources with financial and other pertinent information regarding the Company as may be reasonably requested by the Buyer to consummate the financings contemplated by the Debt Commitment Letter, including all financial statements and financial data required to consummate the financing at the time during the Company’s fiscal year such offering will be made if such offering were registered under the Securities Act and of the type and form customarily included in private placements under Rule 144A of the Securities Act (the “Required Financial Information”) (and shall allow the Buyer’s Representative the opportunity to review and comment upon the financial statements (including pro forma financial statements) in draft form to the extent such financial statements were not prepared prior to the date hereof), (iii) assisting the Buyer in preparing materials for rating agency presentations, bank information memoranda, offering memoranda, private placement memoranda and similar documents, (iv) providing and executing documents as may reasonably be requested by the Buyer, (v) using commercially reasonable efforts to obtain surveys and title insurance as may be reasonably requested by the Buyer, and (vi) reasonably facilitating the pledge of collateral. The Company shall also use reasonable best efforts to cause legal counsel to provide customary legal opinions and an independent auditor of the Company to provide any unqualified opinions, consents or customary comfort letters with respect to its financial statements. The Company shall allow the Buyer’s Representatives the opportunity to review and comment upon any such financial statements (including pro forma financial statements) in draft form and to allow such Representatives access to the Company and supporting documentation with respect to the preparation of such financial statements and the independent auditors’ work papers relating to such financial statements. Notwithstanding the foregoing, (i) such requested cooperation shall not unreasonably interfere with the ongoing operations of the Company and its Subsidiaries and (ii) neither the Company nor any of its Subsidiaries shall be required to pay any commitment or other similar fee or incur any other liability in connection with the financings contemplated by the Commitment Letters prior to the Effective Time. If this Agreement is terminated prior to the Effective Time, the Buyer shall, promptly upon request by the Company, reimburse the Company for all reasonable out-of-pocket costs incurred by the Company or any of its Subsidiaries in connection with such cooperation. If this Agreement is terminated prior to the Effective Time, the Buyer and the Transitory Subsidiary shall, on a joint and several basis, indemnify and hold harmless the Company and its Representatives from and against any and all liabilities, losses, damages, claims, costs, expenses, interest, awards, judgments and penalties suffered or incurred by any of them in connection with the arrangement of the financings contemplated by the Commitment Letters and any information utilized in connection therewith (other than information relating to the Company provided by the Company for use therein).

Each Indemnified Party will be entitled, subject to applicable law, to advancement of expenses incurred in the defense of any such claim, action, suit, proceeding or investigation from the Surviving Corporation within ten Business Days of receipt by the Surviving Corporation from the Indemnified Party of a request therefor; provided that any person to whom expenses are advanced provides an undertaking, to the extent then required by the MBCA, to repay such advances if it is ultimately determined that such person is not entitled to indemnification. In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such determination shall presume that each Indemnified Party is entitled to indemnification and the other benefits of this Section 6.8. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence.

respect to directors’, officers’ and fiduciaries’ liability insurance with respect to matters existing or occurring at or prior to the Effective Time (including the transactions contemplated by this Agreement) in an amount and scope at least as favorable as the coverage applicable to directors and officers as of the date hereof under the Company’s directors’ and officers’ liability insurance policy; provided that if such “tail” or other policies are not available at a cost not greater than 200% of the annual premiums paid as of the date hereof under such policy (the “Insurance Cap”) (which premium the Company hereby represents and warrants is as set forth on Section 6.8(c) of the Company Disclosure Schedule), then the Surviving Corporation shall be required to obtain as much coverage as is possible under substantially similar policies for such annual premiums as do not exceed the Insurance Cap.

6.9Notification of Certain Matters. During the Pre-Closing Period, the Buyer shall give prompt notice to the Company, and the Company shall give prompt notice to the Buyer, of (a) the occurrence, or failure to occur, of any event, which occurrence or failure to occur is reasonably likely to cause any 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 Buyer and the Transitory Subsidiary or the Company, as the case may be, or of any officer, director, employee or agent thereof, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement. Notwithstanding the above, 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.

6.10Exemption from Liability Under Section 16. Prior to the Closing, the Company shall take all such steps as may be required to cause to be exempt under Rule 16b-3 promulgated under the Exchange Act any dispositions of Company Common Stock (including derivative securities with respect to Company Common Stock) under such rule and result from the transactions contemplated by Articles I and II of this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company.

Buyer Employee Plans (as defined below), (b) determination of benefit levels under any Buyer Employee Plan or policy relating to vacation or severance and (c) determination of “retiree” status under any Buyer Employee Plan, in each case for which the Continuing Employee is otherwise eligible and in which the Continuing Employee is offered participation, but except where such credit would result in a duplication of benefits. In addition, the Buyer shall waive, or cause to be waived, any limitations on benefits relating to pre-existing conditions to the same extent such limitations are waived under any comparable plan of the Buyer and recognize for purposes of annual deductible and out-of-pocket limits under its medical and dental plans, deductible and out-of-pocket expenses paid by Continuing Employees in the calendar year in which the Effective Time occurs. For purposes of this Agreement, the term “Buyer Employee Plan” means any “employee pension benefit plan” (as defined in Section 3(2) of ERISA), any “employee welfare benefit plan” (as defined in Section 3(1) of ERISA), and any other written or oral plan, agreement or arrangement, including insurance coverage, severance benefits, disability benefits, deferred compensation, bonuses, stock options, stock purchase, phantom stock, stock appreciation or other forms of incentive compensation or post-retirement compensation and all unexpired severance agreements, for the benefit of, or relating to, any current or former employee of the Buyer or any of its Subsidiaries or any entity which is a member of (A) a controlled group of corporations (as defined in Section 414(b) of the Code), (B) a group of trades or businesses under common control (as defined in Section 414(c) of the Code) or (C) an affiliated service group (as defined in Section 414(m) of the Code or the regulations under Section 414(o) of the Code), any of which includes the Buyer or a Subsidiary of the Buyer.

The Company shall use its reasonable best efforts to obtain and deliver to the Buyer at the Closing evidence reasonably satisfactory to the Buyer of the resignation, effective as of the Effective Time, of those directors of the Company designated by the Buyer to the Company in writing at least twenty calendar days prior to the Closing.

6.14Management Agreements. The Buyer will not enter into any contracts or agreements with any of the officers and directors of the Company unless such contracts or agreements have been provided or made available to the Company Board.

6.15Freely Available Cash. The Company shall use reasonable best efforts, subject to Section 5.1 above, at the Buyer’s request, to liquidate marketable securities and to transfer such cash to the Company (from any Subsidiaries of the Company) or into the Exchange Fund (to the extent such actions are not inconsistent with applicable laws, including those related to solvency, adequate surplus and similar capital adequacy tests). Before taking any such action in accordance with such request, the Company shall disclose to the Buyer the losses, costs, and expenses that the Company expects to incur in connection with such action. To the extent action taken by the Company in accordance with such request causes the Company to incur any losses, costs or expenses (other than losses, costs or expenses resulting from wrongful acts or omissions on the part of the Company), the Buyer shall reimburse such losses, costs and expenses in the event the Closing does not occur. Except for actions pursuant to this Section 6.15, the Company shall not (i) fail to manage and retain cash and cash equivalents and investments in marketable securities in a manner substantially consistent with past practice and in their current jurisdiction or (ii) intentionally fail to manage accounts payable or accounts receivable in a manner substantially consistent with past practice.

The expenses payable pursuant to this Section 8.3(b) shall be paid by wire transfer of same-day funds concurrently (and as a condition to the effectiveness of) any termination by the Company giving rise to the payment obligation described in this Section 8.3(b) or within ten Business Days following any termination by the Buyer giving rise to the payment obligation described in this Section 8.3(b).

(c) The Company shall pay the Buyer or its designee a termination fee of $55.0 million (the “Company Termination Fee”) in the event of the termination of this Agreement pursuant to Section 8.1(e), Section 8.1(f) or Section 8.1(j). The Company shall pay the Buyer or its designee the Company Termination Fee in the event of any termination of this Agreement pursuant to Section 8.1(b), Section 8.1(d) or Section 8.1(g) if, (x) prior to the date of such termination (but after the date hereof), a bona fide Acquisition Proposal is publicly announced or is otherwise communicated, made or proposed in writing to the Company Board, and (y) within twelve (12) months after the date of such termination the Company enters into a definitive agreement with respect to, or closes, any transaction of the type described in the definition of “Acquisition Proposal” (except that all references to “20%” in such definition shall be changed to “50%”). Any Company Termination Fee due under the first sentence of this Section 8.3(c) shall be paid to the Buyer by wire transfer of same-day funds concurrently (and as a condition to the effectiveness of) any termination by the Company giving rise to the payment obligation described in such sentence or within two Business Days following any termination by the Buyer giving rise to the payment obligation described in such sentence.

(d) The Buyer shall pay the Company up to $5 million as reimbursement for expenses of the Company actually incurred relating to the transactions contemplated by this Agreement prior to termination (including, but not limited to, reasonable fees and expenses of the Company’s counsel, accountants and financial advisors, but excluding any discretionary fees paid to such financial advisors), in the event of the termination of this Agreement:

(i) by the Company or the Buyer pursuant to Section 8.1(b) if the failure to satisfy the conditions set forth in Section 7.3(a) or Section 7.3(b) by the Outside Date shall have resulted in the Closing not occurring; or

(ii) by the Company pursuant to Section 8.1(h).

The expenses payable pursuant to this Section 8.3(d) shall be paid by wire transfer of same-day funds concurrently (and as a condition to the effectiveness of) any termination by the Buyer giving rise to the payment obligation described in this Section 8.3(d) or within ten Business Days following any termination by the Company giving rise to the payment obligation described in this Section 8.3(d).

(e) The Buyer shall pay the Company a termination fee of $55.0 million (the “Buyer Termination Fee”) in the event of the termination of this Agreement pursuant to Section 8.1(i); provided that, at the time of such termination, all of the conditions under Section 7.1 and Section 7.2 have been satisfied. Any Buyer Termination Fee due under this Section 8.3(e) shall be paid to the Company by wire transfer of same-day

funds within two Business Days after the date of termination of this Agreement. If the Buyer Termination Fee is paid, and the Buyer and Transitory Subsidiary are not otherwise in willful breach of this Agreement (other than any such breach arising from the failure by the Buyer, after complying with its obligations under Section 5.3 of this Agreement, to obtain the Debt Financing), then the Company’s termination of this Agreement and receipt of payment of the Buyer Termination Fee shall be the sole and exclusive remedy against the Buyer, Transitory Subsidiary, the Guarantors and any of their respective Representatives, Affiliates, directors, officers, employees, partners, managers, members, or stockholders (each, a “Buyer Party”) for any loss or damage suffered as a result of the breach of this Agreement or any representation, warranty, covenant or agreement contained herein by the Buyer or Transitory Subsidiary or the failure of the Merger to be consummated or otherwise in connection with this Agreement or the transactions contemplated hereby (such losses or damages, collectively, “Company Damages”). Notwithstanding anything to the contrary in this Agreement, the maximum aggregate liability of all the Buyer Parties for all Company Damages shall be limited to $137.0 million (the “Buyer Liability Limitation”) (it being understood that, for all purposes of determining whether the aggregate amount of Company Damages paid by the Buyer Parties has reached the Buyer Liability Limitation, the amount paid in respect of the Buyer Termination Fee or expenses paid pursuant toSection 8.3(d) shall be included in such computation as Company Damages paid). In no event shall the Company seek, and the Company shall cause its Subsidiaries not to seek, any Company Damages or any other recovery, judgment, or damages of any kind, including consequential, indirect, or punitive damages, against any Buyer Party in excess of the Buyer Liability Limitation from any Buyer Party in connection therewith and the Company, its Affiliates and its Subsidiaries shall be precluded from any other remedy against any Buyer Party at law or in equity or otherwise. In addition, notwithstanding anything to the contrary in this Agreement, in all cases, the maximum liability of any Guarantor, directly or indirectly, shall be limited to the express obligations of such Guarantor under its Guarantee.

(f) The parties acknowledge that the agreements contained in this Section 8.3 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the parties would not enter into this Agreement. Payment of the fees and expenses described in this Section 8.3 shall not be in lieu of damages incurred in the event of a willful breach of this Agreement described in clause (a) of Section 8.2 but otherwise is the sole and exclusive remedy of the parties in connection with any termination of this Agreement or the circumstances giving rise to such termination.

8.4Amendment. 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 shareholders of any party, but, after any such approval, no amendment shall be made which by law requires further approval by such shareholders 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.

8.5Extension; Waiver. At any time prior to the Effective Time, the parties hereto, by action taken or authorized by their respective Boards of Directors, may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (ii) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (iii) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party. Such extension or waiver shall not be deemed to apply to any time for performance, inaccuracy in any representation or warranty, or noncompliance with any agreement or condition, as the case may be, other than that which is specified in the extension or waiver. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

9.10Remedies. 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 by the Company in accordance with their specific terms or were otherwise breached. It is accordingly agreed, that, without considering the adequacy of any remedy that the Buyer may otherwise have to terminate this Agreement under Section 8.1, the Buyer and the Transitory Subsidiary 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. The parties further acknowledge that the Company shall not be entitled to an injunction or injunctions to prevent breaches of this Agreement by Buyer or Transitory Subsidiary or to enforce specifically the terms and provisions of this Agreement and that the Company’s sole and exclusive remedy with respect to any such breach shall be the Buyer Termination Fee (if applicable) and, if applicable, the other remedies at law available to the Company to the extent set forth in Section 8.3 (subject to the Buyer Liability Limitation); provided, however, that the Company shall be entitled to specific performance against the Buyer and Transitory Subsidiary to prevent any breach by the Buyer or Transitory Subsidiary of Sections 5.2 or 6.4.

9.11Submission 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.

Section 1. Annual Meeting. The Corporation shall hold an annual meeting of shareholders at a time fixed by the Directors. The purposes for which the annual meeting is to be held, in addition to those prescribed by the Articles of Organization, shall be for electing directors and for such other purposes as shall be specified in the notice for the meeting, and only business within such purposes may be conducted at the meeting. In the event an annual meeting is not held at the time fixed in accordance with these Bylaws or the time for an annual meeting is not fixed in accordance with these Bylaws to be held within 13 months after the last annual meeting was held, the Corporation may designate a special meeting held thereafter as a special meeting in lieu of the annual meeting, and the meeting shall have all of the effect of an annual meeting.

Section 2. Special Meetings. Special meetings of the shareholders may be called by the President or by the Directors, and shall be called by the Secretary, or in case of the death, absence, incapacity or refusal of the Secretary, by another officer, if the holders of at least 10 per cent, or such lesser percentage as the Articles of Organization permit, of all the votes entitled to be cast on any issue to be considered at the proposed special meeting sign, date, and deliver to the Secretary one or more written demands for the meeting describing the purpose for which it is to be held. Only business within the purpose or purposes described in the meeting notice may be conducted at a special shareholders’ meeting.

Section 3. Place of Meetings. All meetings of shareholders shall be held at the principal office of the Corporation unless a different place is specified in the notice of the meeting.

Section 4. Requirement of Notice. A written notice of the date, time, and place of each annual and special shareholders’ meeting describing the purposes of the meeting shall be given to shareholders entitled to vote at the meeting no fewer than seven nor more than 60 days before the meeting date. If an annual or special meeting of shareholders is adjourned to a different date, time or place, notice need not be given of the new date, time or place if the new date, time or place, if any, is announced at the meeting before adjournment. If a new record date for the adjourned meeting is fixed, however, notice of the adjourned meeting shall be given under this section to persons who are shareholders as of the new record date. All notices to shareholders shall conform to the requirements of Article III.

Section 5. Waiver of Notice. A shareholder may waive any notice required by law, the Articles of Organization, or these Bylaws before or after the date and time stated in the notice. The waiver shall be in writing, be signed by the shareholder entitled to the notice, and be delivered to the Corporation for inclusion with the records of the meeting. A shareholder’s attendance at a meeting: (a) waives objection to lack of notice or defective notice of the meeting, unless the shareholder at the beginning of the meeting objects to holding the meeting or transacting business at the meeting; and (b) waives objection to consideration of a particular matter at the meeting that is not within the purpose or purposes described in the meeting notice, unless the shareholder objects to considering the matter when it is presented.

Section 6. Quorum.

(a) Unless otherwise provided by law, or in the Articles of Organization, these Bylaws or a resolution of the Directors requiring satisfaction of a greater quorum requirement for any voting group; a majority of the votes entitled to be cast on the matter by a voting group constitutes a quorum of that voting group for action on that matter. As used in these Bylaws, a voting group includes all shares of one or more classes or series that, under the Articles of Organization or the Massachusetts Business Corporation Act, as in effect from time to time (the “MBCA”), are entitled to vote and to be counted together collectively on a matter at a meeting of shareholders.

(b) A share once represented for any purpose at a meeting is deemed present for quorum purposes for the remainder of the meeting and for any adjournment of that meeting unless (1) the shareholder attends solely to object to lack of notice, defective notice or the conduct of the meeting on other grounds and does not vote the shares or otherwise consent that they are to be deemed present, or (2) in the case of an adjournment, a new record date is or shall be set for that adjourned meeting.

Section 7. Voting and Proxies. Unless the Articles of Organization provide otherwise, each outstanding share, regardless of class, is entitled to one vote on each matter voted on at a shareholders’ meeting. A shareholder may vote his or her shares in person or may appoint a proxy to vote or otherwise act for him or her by signing an appointment form, either personally or by his or her attorney-in-fact. An appointment of a proxy is effective when received by the secretary or other officer or agent authorized to tabulate votes. Unless otherwise provided in the appointment form, an appointment is valid for a period of 11 months from the date the shareholder signed the form or, if it is undated, from the date of its receipt by the officer or agent. An appointment of a proxy is revocable by the shareholder unless the appointment form conspicuously states that it is irrevocable and the appointment is coupled with an interest, as defined in the MBCA. An appointment made irrevocable is revoked when the interest with which it is coupled is extinguished. The death or incapacity of the shareholder appointing a proxy shall not affect the right of the Corporation to accept the proxy’s authority unless notice of the death or incapacity is received by the secretary or other officer or agent authorized to tabulate votes before the proxy exercises his or her authority under the appointment. A transferee for value of shares subject to an irrevocable appointment may revoke the appointment if he or she did not know of its existence when he or she acquired the shares and the existence of the irrevocable appointment was not noted conspicuously on the certificate representing the shares or on the information statement for shares without certificates. Subject to the provisions of Section

7.24 of the MBCA and to any express limitation on the proxy’s authority appearing on the face of the appointment form, the Corporation is entitled to accept the proxy’s vote or other action as that of the shareholder making the appointment.

Section 8. Action at Meeting. If a quorum of a voting group exists, favorable action on a matter, other than the election of Directors, is taken by a voting group if the votes cast within the group favoring the action exceed the votes cast opposing the action, unless a greater number of affirmative votes is required by law, or the Articles of Organization, these Bylaws or a resolution of the Board of Directors requiring receipt of a greater affirmative vote of the shareholders, including more separate voting groups. Directors are elected by a plurality of the votes cast by the shares entitled to vote in the election at a meeting at which a quorum is present. No ballot shall be required for such election unless requested by a shareholder present or represented at the meeting and entitled to vote in the election.

Section 9. Action without Meeting by Written Consent.

(a) Action taken at a shareholders’ meeting may be taken without a meeting if the action is taken either: (1) by all shareholders entitled to vote on the action; or (2) to the extent permitted by the Articles of Organization, by shareholders having not less than the minimum number of votes necessary to take the action at a meeting at which all shareholders entitled to vote on the action are present and voting. The action shall be evidenced by one or more written consents that describe the action taken, are signed by shareholders having the requisite votes, bear the date of the signatures of such shareholders, and are delivered to the Corporation for inclusion with the records of meetings within 60 days of the earliest dated consent delivered to the Corporation as required by this section. A consent signed under this section has the effect of a vote at a meeting.

(b) If action is to be taken pursuant to the consent of voting shareholders without a meeting, the Corporation, at least seven days before the action pursuant to the consent is taken, shall give notice, which complies in form with the requirements of Article III, of the action (1) to nonvoting shareholders in any case where such notice would be required by law if the action were to be taken pursuant to a vote by voting shareholders at a meeting, and (2) if the action is to be taken pursuant to the consent of less than all the shareholders entitled to vote on the matter, to all shareholders entitled to vote who did not consent to the action. The notice shall contain, or be accompanied by, the same material that would have been required by law to be sent to shareholders in or with the notice of a meeting at which the action would have been submitted to the shareholders for approval.

Section 10. Record Date. The Directors may fix the record date in order to determine the shareholders entitled to notice of a shareholders’ meeting, to demand a special meeting, to vote, or to take any other action. If a record date for a specific action is not fixed by the Board of Directors, and is not supplied by law, the record date shall be the close of business either on the day before the first notice is sent to shareholders, or, if no notice is sent, on the day before the meeting or, in the case of action without a meeting by written consent, the date the first shareholder signs the consent. A record date fixed under this section may not be more than 70 days before the meeting or action requiring a determination of shareholders. A determination of shareholders entitled to notice of or to vote at a shareholders’ meeting is effective for any

adjournment of the meeting unless the Board of Directors fixes a new record date, which it shall do if the meeting is adjourned to a date more than 120 days after the date fixed for the original meeting.

Section 11. Meetings by Remote Communications. Unless otherwise provided in the Articles of Organization, if authorized by the Directors: any annual or special meeting of shareholders need not be held at any place but may instead be held solely by means of remote communication; and subject to such guidelines and procedures as the Board of Directors may adopt, shareholders and proxyholders not physically present at a meeting of shareholders may, by means of remote communications: (a) participate in a meeting of shareholders; and (b) be deemed present in person and vote at a meeting of shareholders whether such meeting is to be held at a designated place or solely by means of remote communication, provided that: (1) the Corporation shall implement reasonable measures to verify that each person deemed present and permitted to vote at the meeting by means of remote communication is a shareholder or proxyholder; (2) the Corporation shall implement reasonable measures to provide such shareholders and proxyholders a reasonable opportunity to participate in the meeting and to vote on matters submitted to the shareholders, including an opportunity to read or hear the proceedings of the meeting substantially concurrently with such proceedings; and (3) if any shareholder or proxyholder votes or takes other action at the meeting by means of remote communication, a record of such vote or other action shall be maintained by the Corporation.

Section 12. Form of Shareholder Action.

(a) Any vote, consent, waiver, proxy appointment or other action by a shareholder or by the proxy or other agent of any shareholder shall be considered given in writing, dated and signed, if, in lieu of any other means permitted by law, it consists of an electronic transmission that sets forth or is delivered with information from which the Corporation can determine (i) that the electronic transmission was transmitted by the shareholder, proxy or agent or by a person authorized to act for the shareholder, proxy or agent; and (ii) the date on which such shareholder, proxy, agent or authorized person transmitted the electronic transmission. The date on which the electronic transmission is transmitted shall be considered to be the date on which it was signed. The electronic transmission shall be considered received by the Corporation if it has been sent to any address specified by the Corporation for the purpose or, if no address has been specified, to the principal office of the Corporation, addressed to the Secretary or other officer or agent having custody of the records of proceedings of shareholders.

(b) Any copy, facsimile or other reliable reproduction of a vote, consent, waiver, proxy appointment or other action by a shareholder or by the proxy or other agent of any shareholder may be substituted or used in lieu of the original writing for any purpose for which the original writing could be used, but the copy, facsimile or other reproduction shall be a complete reproduction of the entire original writing.

Section 13. Shareholders List for Meeting.

(a) After fixing a record date for a shareholders’ meeting, the Corporation shall prepare an alphabetical list of the names of all its shareholders who are entitled to notice of the meeting. The list shall be arranged by voting group, and within each voting group by class or

series of shares, and show the address of and number of shares held by each shareholder, but need not include an electronic mail address or other electronic contact information for any shareholder.

(b) The shareholders list shall be available for inspection by any shareholder, beginning two business days after notice is given of the meeting for which the list was prepared and continuing through the meeting: (1) at the Corporation’s principal office or at a place identified in the meeting notice in the city where the meeting will be held; or (2) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting. If the meeting is to be held solely by means of remote communication, the list shall be made available on an electronic network.

(c) A shareholder, his or her agent, or attorney is entitled on written demand to inspect and, subject to the requirements of Section 2(b) of Article V of these Bylaws, to copy the list, during regular business hours and at his or her expense, during the period it is available for inspection.

(d) The Corporation shall make the shareholders list available at the meeting, and any shareholder or his or her agent or attorney is entitled to inspect the list at any time during the meeting or any adjournment.

ARTICLE II

DIRECTORS

Section 1. Powers. All corporate power shall be exercised by or under the authority of, and the business and affairs of the Corporation shall be managed under the direction of, its Board of Directors.

Section 2. Number and Election. The Board of Directors shall consist of one or more individuals, with the number fixed by the shareholders at the annual meeting, but, unless otherwise provided in the Articles of Organization, if the Corporation has more than one shareholder, the number of Directors shall not be less than three, except that whenever there shall be only two shareholders, the number of Directors shall not be less than two. Except as otherwise provided in these Bylaws or the Articles of Organization, the number of Directors shall be fixed, and the Directors elected, by the shareholders at the annual meeting.

Section 3. Vacancies. If a vacancy occurs on the Board of Directors, including a vacancy resulting from an increase in the number of Directors: (a) the shareholders may fill the vacancy; (b) the Board of Directors may fill the vacancy; or (c) if the Directors remaining in office constitute fewer than a quorum of the Board, they may fill the vacancy by the affirmative vote of a majority of all the Directors remaining in office. A vacancy that will occur at a specific later date may be filled before the vacancy occurs but the new Director may not take office until the vacancy occurs.

Section 4. Change in Size of the Board of Directors. The number of Directors may be fixed or changed from time to time by the shareholders, and the Board of Directors may increase or decrease the number of Directors last approved by the shareholders.

Section 5. Tenure. The terms of all Directors shall expire at the next annual shareholders’ meeting following their election. A decrease in the number of Directors does not shorten an incumbent Director’s term. The term of a Director elected to fill a vacancy shall expire at the next shareholders’ meeting at which Directors are elected. Despite the expiration of a Director’s term, he or she shall continue to serve until his or her successor is elected and qualified or until there is a decrease in the number of Directors.

Section 6. Resignation. A Director may resign at any time by delivering written notice of resignation to the Board of Directors, its chairman, or to the Corporation. A resignation is effective when the notice is delivered unless the notice specifies a later effective date.

Section 7. Removal. The shareholders may remove one or more Directors with or without cause. A Director may be removed for cause by the Directors by vote of a majority of the Directors then in office. A Director may be removed by the shareholders or the Directors only at a meeting called for the purpose of removing him or her and the meeting notice must state that the purpose, or one of the purposes, of the meeting is removal of the Director.

Section 8. Regular Meetings. Regular meetings of the Board of Directors may be held at such times and places as shall from time to time be fixed by the Board of Directors without notice of the date, time, place or purpose of the meeting.

Section 9. Special Meetings. Special meetings of the Board of Directors may be called by the President, by the Secretary, by any two Directors, or by one Director in the event that there is only one Director.

Section 10. Notice. Special meetings of the Board must be preceded by at least two days’ notice of the date, time and place of the meeting. The notice need not describe the purpose of the special meeting. All notices to directors shall conform to the requirements of Article III.

Section 11. Waiver of Notice. A Director may waive any notice before or after the date and time of the meeting. The waiver shall be in writing, signed by the Director entitled to the notice, or in the form of an electronic transmission by the Director to the Corporation, and filed with the minutes or corporate records. A Director’s attendance at or participation in a meeting waives any required notice to him or her of the meeting unless the Director at the beginning of the meeting, or promptly upon his or her arrival, objects to holding the meeting or transacting business at the meeting and does not thereafter vote for or assent to action taken at the meeting.

Section 12. Quorum. A quorum of the Board of Directors consists of a majority of the Directors then in office, provided always that any number of Directors (whether one or more and whether or not constituting a quorum) constituting a majority of Directors present at any meeting or at any adjourned meeting may make any reasonable adjournment thereof.

Section 13. Action at Meeting. If a quorum is present when a vote is taken, the affirmative vote of a majority of Directors present is the act of the Board of Directors. A Director who is present at a meeting of the Board of Directors or a committee of the Board of Directors when corporate action is taken is considered to have assented to the action taken unless: (a) he objects at the beginning of the meeting, or promptly upon his arrival, to holding it or transacting business at the meeting; (b) his dissent or abstention from the action taken is entered in the

minutes of the meeting; or (c) he delivers written notice of his dissent or abstention to the presiding officer of the meeting before its adjournment or to the Corporation immediately after adjournment of the meeting. The right of dissent or abstention is not available to a Director who votes in favor of the action taken.

Section 14. Action Without Meeting. Any action required or permitted to be taken by the Directors may be taken without a meeting if the action is taken by the unanimous consent of the members of the Board of Directors. The action must be evidenced by one or more consents describing the action taken, in writing, signed by each Director, or delivered to the Corporation by electronic transmission, to the address specified by the Corporation for the purpose or, if no address has been specified, to the principal office of the Corporation, addressed to the Secretary or other officer or agent having custody of the records of proceedings of Directors, and included in the minutes or filed with the corporate records reflecting the action taken. Action taken under this section is effective when the last Director signs or delivers the consent, unless the consent specifies a different effective date. A consent signed or delivered under this section has the effect of a meeting vote and may be described as such in any document.

Section 15. Telephone Conference Meetings. The Board of Directors may permit any or all Directors to participate in a regular or special meeting by, or conduct the meeting through the use of, any means of communication by which all Directors participating may simultaneously hear each other during the meeting. A Director participating in a meeting by this means is considered to be present in person at the meeting.

Section 16. Committees. The Board of Directors may create one or more committees and appoint members of the Board of Directors to serve on them. Each committee may have one or more members, who serve at the pleasure of the Board of Directors. The creation of a committee and appointment of members to it must be approved by a majority of all the Directors in office when the action is taken. Sections 11 through 15 of this Article shall apply to committees and their members. To the extent specified by the Board of Directors, each committee may exercise the authority of the Board of Directors. A committee may not, however:

(a) authorize distributions; (b) approve or propose to shareholders action that the MBCA requires be approved by shareholders; (c) change the number of the Board of Directors, remove Directors from office or fill vacancies on the Board of Directors; (d) amend the Articles of Organization; (e) adopt, amend or repeal Bylaws; or (1) authorize or approve reacquisition of shares, except according to a formula or method prescribed by the Board of Directors. The creation of, delegation of authority to, or action by a committee does not alone constitute compliance, by a Director with the standards of conduct described in Section 18 of this Article.

Section 17. Compensation. The Board of Directors may fix the compensation of Directors.

Section 18. Standard of Conduct for Directors.

(a) A Director shall discharge his or her duties as a Director, including his or her duties as a member of a committee: (1) in good faith; (2) with the care that a person in a like position would reasonably believe appropriate under similar circumstances; and (3) in a manner the

Director reasonably believes to be in the best interests of the Corporation. In determining what the Director reasonably believes to be in the best interests of the Corporation, a Director may consider the interests of the Corporation’s employees, suppliers, creditors and customers, the economy of the state, the region and the nation, community and societal considerations, and the long-term and short-term interests of the Corporation and its shareholders, including the possibility that these interests may be best served by the continued independence of the Corporation.

(b) In discharging his or her duties, a Director who does not have knowledge that makes reliance unwarranted is entitled to rely on information, opinions, reports, or statements, including financial statements and other financial data, if prepared or presented by: (1) one or more officers or employees of the Corporation whom the Director reasonably believes to be reliable and competent with respect to the information, opinions, reports or statements presented; (2) legal counsel, public accountants, or other persons retained by the Corporation, as to matters involving skills or expertise the Director reasonably believes are matters (i) within the particular person’s professional or expert competence or (ii) as to which the particular person merits confidence; or (3) a committee of the Board of Directors of which the Director is not a member if the Director reasonably believes the committee merits confidence.

(c) A Director is not liable for any action taken as a Director, or any failure to take any action, if he or she performed the duties of his or her office in compliance with this Section.

Section 19. Conflict of Interest.

(a) A conflict of interest transaction is a transaction with the Corporation in which a Director of the Corporation has a material direct or indirect interest. A conflict of interest transaction is not voidable by the Corporation solely because of the Director’s interest in the transaction if any one of the following is true:

(1) the material facts of the transaction and the Director’s interest were disclosed or known to the Board of Directors or a committee of the Board, of Directors and the Board of Directors or committee authorized, approved, or ratified the transaction;

(2) the material facts of the transaction and the Director’s interest were disclosed or known to the shareholders entitled to vote and they authorized, approved, or ratified the transaction; or

(3) the transaction was fair to the Corporation.

(b) For purposes of this section, and without limiting the interests that may create conflict of interest transactions, a Director of the Corporation has an indirect interest in a transaction if: (1) another entity in which he or she has a material financial interest or in which he or she is a general partner is a party to the transaction; or (2) another entry of which he or she is a director, officer, or trustee or in which he or she holds another position is a party to the transaction and the transaction is or should be considered by the Board of Directors of the Corporation.

(c) For purposes of clause (1) of subsection (a), a conflict of interest transaction is authorized, approved, or ratified if it receives the affirmative vote of a majority of the Directors

on the Board of Directors (or on the committee) who have no direct or indirect interest in the transaction, but a transaction may not be authorized, approved, or ratified under this Section by a single Director. If a majority of the Directors who have no direct or indirect interest in the transaction vote to authorize, approve, or ratify the transaction, a quorum is present for the purpose of taking action under this section. The presence of, or a vote cast by, a Director with a direct or indirect interest in the transaction does not affect the validity of any action taken under clause (1) of subsection (a) if the transaction is otherwise authorized, approved, or ratified as provided in that subsection.

(d) For purposes of clause (2) of subsection (a), a conflict of interest transaction is authorized, approved, or ratified if it receives the vote of a majority of the shares entitled to be counted under this subsection. Shares owned by or voted under the control of a Director who has a direct or indirect interest in the transaction, and shares owned by or voted under the control of an entity described in clause (1) of subsection (b), may not be counted in a vote of shareholders to determine whether to authorize, approve, or ratify a conflict of interest transaction under clause (2) of subsection (a). The vote of those shares, however, is counted in determining whether the transaction is approved under other sections of these Bylaws. A majority of the shares, whether or not present, that are entitled to be counted in a vote on the transaction under this subsection constitutes a quorum for the purpose of taking action under this Section.

Section 20. Loans to Directors. The Corporation may not lend money to, or guarantee the obligation of a Director of, the Corporation unless: (a) the specific loan or guarantee is approved by a majority of the votes represented by the outstanding voting shares of all classes, voting as a single voting group, except the votes of shares owned by or voted under the control of the benefited Director; or (b) the Corporation’s Board of Directors determines that the loan or guarantee benefits the Corporation and either approves the specific loan or guarantee or a general plan authorizing loans and guarantees. The fact that a loan or guarantee is made in violation of this Section shall not affect the borrower’s liability on the loan.

ARTICLE V

PROVISIONS RELATING TO SHARES

Section 1. Issuance, and Consideration. The Board of Directors may issue the number of shares of each class or series authorized by the Articles of Organization. The Board of Directors may authorize shares to be issued for consideration consisting of any tangible or intangible property or benefit to the Corporation, including cash, promissory notes, services performed, contracts for services to be performed, or other securities of the Corporation. Before the Corporation issues shares, the Board of Directors shall determine that the consideration received or to be received for shares to be issued is adequate. The Board of Directors shall determine the terms upon which the rights, options, or warrants for the purchase of shares or other securities of the Corporation are issued and the terms, including the consideration, for which the shares or other securities are to be issued.

Section 2. Share Certificates. If shares are represented by certificates, at a minimum each share certificate shall state on its face: (a) the name of the Corporation and that it is organized under the laws of The Commonwealth of Massachusetts; (b) the name of the person to whom issued; and (c) the number and class of shares and the designation of the series, if any, the certificate represents. If different classes of shares or different series within a class are authorized, then the variations in rights, preferences and limitations applicable to each class and series, and the authority of the Board of Directors to determine variations for any future class or series, must be summarized on the front or back of each certificate. Alternatively, each certificate may state conspicuously on its front or back that the Corporation will furnish the shareholder this information on request in writing and without charge. Each share certificate shall be signed, either manually or in facsimile, by the President or a Vice President and by the Treasurer or an Assistant Treasurer, or any two officers designated by the Board of Directors, and shall bear the corporate seal or its facsimile. If the person who signed, either manually or in facsimile, a share certificate no longer holds office when the certificate is issued, the certificate shall be nevertheless valid.

Section 3. Uncertificated Shares. The Board of Directors may authorize the issue of some or all of the shares of any or all of the Corporation’s classes or series without certificates. The authorization shall not affect shares already represented by certificates until they are surrendered to the Corporation. Within a reasonable time after the issue or transfer of shares without certificates, the Corporation shall send the shareholder a written statement of the information required by the MBCA to be on certificates.

“Director” or “officer”, an individual who is or was a Director or officer, respectively, of the Corporation or who, while a Director or officer of the Corporation, is or was serving at the Corporation’s request as a director, officer, partner, trustee, employee, or agent of another domestic or foreign corporation, partnership, joint venture, trust, employee benefit plan, or other entity. A Director or officer is considered to be serving an employee benefit plan at the Corporation’s request if his or her duties to the Corporation also impose duties on, or otherwise involve services by, him or her to the plan or to participants in or beneficiaries of the plan. “Director” or “officer” includes, unless the context requires otherwise, the estate or personal representative of a Director or officer.

“Disinterested Director”, a Director who, at the time of a vote or selection referred to in Section 4 of this Article, is not (i) a party to the proceeding, or (ii) an individual having a familial, financial, professional, or employment relationship with the Director whose indemnification or advance for expenses is the subject of the decision being made, which relationship would, in the circumstances, reasonably be expected to exert an influence on the Director’s judgment when voting on the decision being made.

“Expenses”, includes counsel fees.

“Liability”, the obligation to pay a judgment, settlement, penalty, fine including an excise tax assessed with respect to an employee benefit plan, or reasonable expenses incurred with respect to a proceeding.

Section 2. Indemnification of Directors and Officers.

(a) Except as otherwise provided in this Section, the Corporation shall indemnify to the fullest extent permitted by law an individual who is a party to a proceeding because he or she is a Director or officer against liability incurred in the proceeding if: (1) (i) he or she conducted himself or herself in good faith; and (ii) he or she reasonably believed that his or her conduct was in the best interests of the Corporation or that his or her conduct was at least not opposed to the best interests of the Corporation; and (iii) in the case of any criminal proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful; or (2) he or she engaged in conduct for which he or she shall not be liable under a provision of the Articles of Organization authorized by Section 2.02(b)(4) of the MBCA or any successor provision to such Section.

(b) A Director’s or officer’s conduct with respect to an employee benefit plan for a purpose he or she reasonably believed to be in the interests of the participants in, and the beneficiaries of, the plan is conduct that satisfies the requirement that his or her conduct was at least not opposed to the best interests of the Corporation.

(c) The termination of a proceeding by judgment, order, settlement, or conviction, or upon a plea of nolo contendere or its equivalent, is not, of itself, determinative that the Director or officer did not meet the relevant standard of conduct described in this Section.

(d) Unless ordered by a court, the Corporation may not indemnify a Director or officer under this Section if his or her conduct did not satisfy the standards set forth in subsection (a) or subsection (b).

Section 3. Advance for Expenses. The Corporation shall, before final disposition of a proceeding, advance funds to pay for or reimburse the reasonable expenses incurred by a Director or officer who is a party to a proceeding because he or she is a Director or officer if he or she delivers to the Corporation:

(a) a written affirmation of his or her good faith belief that he or she has met the relevant standard of conduct described in Section 2 of this Article or that the proceeding involves conduct for which liability has been eliminated under a provision of the Articles of Organization as authorized by Section 2.02(b)(4) of the MBCA; and

(b) his or her written undertaking to repay any funds advanced if he or she is not wholly successful, on the merits or otherwise, in the defense of such proceeding and it is ultimately

determined pursuant to Section 4 of this Article or by a court of competent jurisdiction that he or she has not met the relevant standard of conduct described in Section 2 of this Article.

Such undertaking need not be secured and shall be accepted without reference to the financial ability of the Director or officer to make repayment.

Section 4. Determination of Indemnification. The determination of whether a Director officer has met the relevant standard of conduct set forth in Section 2 shall be made:

(a) if there are two or more disinterested Directors, by the Board of Directors by a majority vote of all the disinterested Directors, a majority of whom shall for such purpose constitute a quorum, or by a majority of the members of a committee of two or more disinterested Directors appointed by vote;

(b) by special legal counsel (1) selected in the manner prescribed in clause (a); or (2) if there are fewer than two disinterested Directors, selected by the Board of Directors, in which selection Directors who do not qualify as disinterested Directors may participate; or

(c) by the shareholders, but shares owned by or voted under the control of a Director who at the time does not qualify as a disinterested Director may not be voted on the determination.

Section 5. Notification and Defense of claim; Settlements.

(a) In addition to and without limiting the foregoing provisions of this Article and except to the extent otherwise required by law, it shall be a condition of the Corporation’s obligation to indemnify under Section 2 of this Article (in addition. to any other condition provide in these Bylaws or by law) that the person asserting, or proposing to assert, the right to be indemnified, must notify the Corporation in writing as soon as practicable of any action, suit, proceeding or investigation involving such person for which indemnity will or could be sought, but the failure to so notify shall not affect the Corporation’s objection to indemnify except to the extent the Corporation is adversely affected thereby. With respect to any proceeding of which the Corporation is so notified, the Corporation will be entitled to participate therein at its own expense and/or to assume the defense thereof at its own expense, with legal counsel reasonably acceptable to such person. After notice from the Corporation to such person of its election so to assume such defense, the Corporation shall not be liable to such person for any legal or other expenses subsequently incurred by such person in connection with such action, suit, proceeding or investigation other than as provided below in this subsection (a). Such person shall have the right to employ his or her own counsel in connection with such action, suit, proceeding or investigation, but the fees and expenses of such counsel incurred after notice from the Corporation of its assumption of the defense thereof shall be at the expense of such person unless (1) the employment of counsel by such person has been authorized by the Corporation, (2) counsel to such person shall have reasonably concluded that there may be a conflict of interest or position on any significant issue between the Corporation and such person in the conduct of the defense of such action, suit, proceeding or investigation or (3) the Corporation shall not in fact have employed counsel to assume the defense of such action, suit, proceeding or investigation, in each of which cases the fees and expenses of counsel for such person shall be at the expense of the Corporation, except as otherwise expressly provided by this Article. The Corporation shall

not be entitled, without the consent of such person, to assume the defense of any claim brought by or in the right of the Corporation or as to which counsel for such person shall have reasonably made the conclusion provided for in clause (2) above.

(b) The Corporation shall not be required to indemnify such person under this Article for any amounts paid in settlement of any proceeding unless authorized in the same manner as the determination that indemnification is permissible under Section 4 of this Article, except that if there are fewer than two disinterested Directors, authorization of indemnification shall be made by the Board of Directors, in which authorization Directors who do not qualify as disinterested Directors may participate. The Corporation shall not settle any action, suit, proceeding or investigation in any manner which would impose any penalty or limitation on such person without such person’s written consent. Neither the Corporation nor such person will unreasonably withhold their consent to any proposed settlement.

Section 6. Insurance. The Corporation may purchase and maintain insurance on behalf of an individual who is a Director or officer of the Corporation, or who, while a Director or officer of the Corporation, serves at the Corporation’s request as a director, officer, partner, trustee, employee, or agent of another domestic or foreign corporation, partnership, joint venture, trust, employee benefit plan, or other entity, against liability asserted against or incurred by him or her in that capacity or arising from his or her status as a Director or officer, whether or not the Corporation would have power to indemnify or advance expenses to him or her against the same liability under this Article.

Section 7. Application of this Article.

(a) The Corporation shall not be obligated to indemnify or advance expenses to a Director or officer of a predecessor of the Corporation, pertaining to conduct with respect to the predecessor, unless otherwise specifically provided.

(b) This Article shall not limit the Corporation’s power to (1) pay or reimburse expenses incurred by a Director or an officer in connection with his or her appearance as a witness in a proceeding at a time when he or she is not a party or (2) indemnify, advance expenses to or provide or maintain insurance on behalf of an employee or agent.

(c) The indemnification and advancement of expenses provided by, or granted pursuant to, this Article shall not be considered exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled.

(d) Each person who is or becomes a Director or officer of the Corporation shall be deemed to have served or to have continued to serve in such capacity in reliance upon the indemnity provided for in this Article. All rights to indemnification under this Article shall be deemed to be provided by a contract between the Corporation and the person who serves as a Director or officer of the Corporation at any time while these By-laws and the relevant provisions of the MBCA are in effect. Any repeal or modification thereof shall not affect any rights or obligations then existing.

ARTICLE VIII

FISCAL YEAR

The fiscal year of the Corporation shall be the year ending with December 31 in each year.

ARTICLE IX

AMENDMENTS

(a) The power to make, amend or repeal these Bylaws shall be in the shareholders. If authorized by the Articles of Organization, the Board of Directors may also make, amend or repeal these Bylaws in whole or in part, except with respect to any provision thereof which by virtue of an express provision in the MBCA, the Articles of Organization, or these Bylaws, requires action by the shareholders.

ANNEX I

GUARANTEE

GUARANTEE, dated as of March 22, 2007 (this “Guarantee”), by(the “Guarantor”), in favor of Kronos Incorporated, a Massachusetts corporation (the “Company”).

1.GUARANTEE. To induce the Company to enter into that certain Agreement and Plan of Merger, dated as of March 22, 2007 (as amended, supplemented or otherwise modified from time to time, the “Merger Agreement”; capitalized terms used but not defined herein shall have the meanings given to such terms in the Merger Agreement), by and among the Company, Seahawk Acquisition Corporation, a Delaware corporation (“Buyer”), and Seahawk Merger Sub Corporation, a Massachusetts corporation and a wholly-owned subsidiary of Buyer (“Transitory Subsidiary”), pursuant to which the Transitory Subsidiary will merge with and into the Company, the Guarantor absolutely, unconditionally and irrevocably guarantees to the Company the due and punctual observance, payment, performance and discharge of % (the “Guaranteed Percentage”) of any payment obligation of the Buyer and the Transitory Subsidiary pursuant to Section 5.3(d), Section 6.15, Section 8.3(d) or Section 8.3(e) of the Merger Agreement, in each case subject to the limitations set forth in Section 8.3(e) of the Merger Agreement (the “Obligations”), provided that in no event shall the Guarantor’s aggregate liability under this Guarantee exceed $ (the “Cap”), it being understood that this Guarantee may not be enforced against the Guarantor without giving effect to the Cap.

In furtherance of the foregoing the Guarantor acknowledges that the Company may, in its sole discretion, bring and prosecute a separate action or actions against the Guarantor for the full amount of the Guarantor’s Guaranteed Percentage of the Obligations (subject to the Cap), regardless of whether action is brought against the Buyer, the Transitory Subsidiary or any other guarantor pursuant to a Guarantee dated as of the date hereof to be entered into between the Company and such other guarantor (the “Other Guarantor”) or whether the Buyer, the Transitory Subsidiary or the Other Guarantor is joined in any such action or actions.

2.NATURE OF GUARANTEE. The Company shall not be obligated to file any claim relating to the Obligations in the event that the Buyer or the Transitory Subsidiary becomes subject to a bankruptcy, reorganization or similar proceeding, and the failure of the Company to so file shall not affect the Guarantor’s obligations hereunder. In the event that any payment to the Company in respect of any Obligations is rescinded or must otherwise be returned for any reason whatsoever, the Guarantor shall remain liable hereunder with respect to its Guaranteed Percentage of such Obligations as if such payment had not been made. This is an unconditional guarantee of payment and not of collectibility. The Guarantor reserves the right to assert defenses which the Buyer or the Transitory Subsidiary may have to payment of any Obligations other than defenses arising from the bankruptcy or insolvency of the Buyer or the Transitory Subsidiary and other defenses expressly waived hereby.

3.CHANGES IN OBLIGATIONS, CERTAIN WAIVERS. The Guarantor agrees that the Company may at any time and from time to time, without notice to or further consent of the Guarantor, extend the time of payment of any of the Obligations, and may also make any agreement with the Buyer or the Transitory Subsidiary for the extension, renewal, payment, compromise, discharge or release thereof, in whole or in part, or for any modification of the terms thereof or of any agreement between the Company and the Buyer or the Transitory Subsidiary or any such other person without in any way impairing or affecting this Guarantee. The Guarantor agrees that the obligations of the Guarantor hereunder shall not be released or discharged, in whole or in part, or otherwise affected by (a) the failure of the Company to assert any claim or demand or to enforce any right or remedy against the Buyer or the Transitory Subsidiary or any other entity or person interested in the transactions contemplated by the Merger Agreement; (b) any change in the time, place or manner of payment of any of the Obligations or any rescission, waiver, compromise, consolidation or other amendment or modification of any of the terms or provisions of the Merger Agreement or any other agreement evidencing, securing or otherwise executed in connection with any of the Obligations; (c) the addition, substitution or release of any other entity or person interested in the transactions contemplated by the Merger Agreement; (d) any change in the corporate

existence, structure or ownership of the Buyer or the Transitory Subsidiary or any other entity or person interested in the transactions contemplated by the Merger Agreement; (e) any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Buyer or the Transitory Subsidiary or any other entity or person interested in the transactions contemplated in the Merger Agreement; (f) the existence of any claim, set-off or other rights which the Guarantor may have at any time against the Buyer, the Transitory Subsidiary or the Company, whether in connection with the Obligations or otherwise; or (g) the adequacy of any other means the Company may have of obtaining payment of the Obligations. To the fullest extent permitted by law, the Guarantor hereby expressly waives any and all rights or defenses arising by reason of any law that would otherwise require any election of remedies by the Company. The Guarantor waives promptness, diligence, notice of the acceptance of this Guarantee and of the Obligations, presentment, demand for payment, notice of non-performance, default, dishonor and protest, notice of any Obligations incurred and all other notices of any kind (except for notices to be provided to the Buyer and the Transitory Subsidiary in accordance with Section 9.2 of the Merger Agreement), all defenses which may be available by virtue of any valuation, stay, moratorium law or other similar law now or hereafter in effect, any right to require the marshalling of assets of the Buyer or the Transitory Subsidiary or any other entity or other person interested in the transactions contemplated by the Merger Agreement, and all suretyship defenses generally (other than fraud or willful misconduct by the Company or any of its Subsidiaries or defenses to the payment of the Obligations that are available to the Buyer or the Transitory Subsidiary under the Merger Agreement or breach by the Company of this Guarantee). The Guarantor acknowledges that it will receive substantial direct and indirect benefits from the transactions contemplated by the Merger Agreement and that the waivers set forth in this Guarantee are knowingly made in contemplation of such benefits. The Company hereby covenants and agrees that it shall not institute, and shall cause its respective Affiliates not to institute, any proceeding or bring any other claim arising under, or in connection with, the Merger Agreement or the transactions contemplated thereby, against the Guarantor or any of any of the Guarantor’s former, current or future directors, officers, agents, Affiliates (other than Buyer, Transitory Subsidiary or Other Guarantor under its guarantee) or employees, or against any of the former, current or future general or limited partners, members, managers or stockholders of the Guarantor or any Affiliate thereof (other than the Buyer, the Transitory Subsidiary or the Other Guarantor under its guarantee) or against any former, current or future directors, officers, agents, Affiliates, general or limited partners, members, managers or stockholders of any of the foregoing (other than the Buyer, the Transitory Subsidiary or the Other Guarantor under its guarantee) (such persons, not including the Buyer, the Transitory Subsidiary or the Other Guarantor, collectively, “Connected Persons”) except for claims against Guarantor under this Guarantee.

4.NO WAIVER; CUMULATIVE RIGHTS. No failure on the part of the Company to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by the Company of any right, remedy or power hereunder preclude any other or future exercise of any right, remedy or power hereunder. Each and every right, remedy and power hereby granted to the Company or allowed it by law or other agreement shall be cumulative and not exclusive of any other, and may be exercised by the Company at any time or from time to time.

9.NO RECOURSE. The Company by its acceptance of the benefits hereof, covenants, agrees and acknowledges that no person other than the Guarantor shall have any obligation hereunder and that no recourse hereunder or under any documents or instruments delivered in connection herewith shall be had against any of the Guarantor’s Connected Persons, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any statute, regulation or other applicable law. The Company acknowledges and agrees that the Buyer and the Transitory Subsidiary have no assets and that no funds are expected to be contributed to the Buyer or the Transitory Subsidiary unless the Closing occurs. The Company further agrees that neither it nor any of its Affiliates have any right of recovery against the Guarantor or any of its Connected Persons, whether by piercing of the corporate veil, by a claim on behalf of the Buyer or the Transitory Subsidiary against the Guarantor or the Buyer’s stockholders or Affiliates, or otherwise, except for the rights under this Guarantee.
