E. Concurrently with the execution of this Agreement and as a condition and inducement to LTX’s and Credence’s willingness to enter into this Agreement, Credence and certain stockholders of LTX are entering into stockholder voting agreements in substantially the form attached hereto as Exhibit A (the “LTX Stockholder Voting Agreements”), and LTX and certain stockholders of Credence are entering into voting agreements in substantially the form attached hereto as Exhibit B (the “Credence Stockholder Voting Agreements” and, collectively with the LTX Voting Agreements, the “Stockholder Voting Agreements”).

ARTICLE I

1.1 The Merger. At the Effective Time (as defined in Section 1.2) and subject to and upon the terms and conditions of this Agreement and the applicable provisions of the DGCL, Merger Sub shall be merged with and into Credence (the “Merger”), the separate corporate existence of Merger Sub shall cease and Credence shall

1.3 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement and the applicable provisions of the DGCL. Without limiting the generality of the foregoing, at the Effective Time all the property, rights, privileges, powers and franchises of Credence and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of Credence and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

1.4 Certificate of Incorporation and Bylaws.

(a) At the Effective Time, the certificate of incorporation of Credence shall be amended in its entirety to read as set forth in Exhibit C hereto and as so amended shall be the certificate of incorporation of the Surviving Corporation, until thereafter amended in accordance with the DGCL and as provided in such certificate of incorporation.

(b) At the Effective Time, the bylaws of Credence shall be amended and restated in their entirety to read as set forth on Exhibit D hereto and as so amended and restated shall be the bylaws of the Surviving Corporation, until thereafter amended in accordance with the DGCL and as provided in such bylaws.

1.5 Directors and Officers. The initial directors of the Surviving Corporation shall be the directors of Merger Sub immediately prior to the Effective Time, until their respective successors are duly elected or appointed and qualified. The initial officers of the Surviving Corporation shall be the officers of Merger Sub immediately prior to the Effective Time, until their respective successors are duly elected or appointed and qualified.

1.6 Effect on Capital Stock. Subject to the terms and conditions of this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of LTX, Merger Sub, Credence or the holders of any of the following securities, the following shall occur:

(a) Credence Common Stock. Each share of common stock, par value $0.001 per share, of Credence (“Credence Common Stock”) issued and outstanding immediately prior to the Effective Time, other than any shares of Credence Common Stock to be canceled pursuant to Section 1.6(b), will each be canceled and extinguished and automatically converted (subject to Section 1.6(e)) into the right to receive that number of validly issued, fully paid and nonassessable shares of common stock of LTX, par value $0.05 per share (“LTX Common Stock”), that is equal to the quotient obtained by dividing (A) the difference between (x) the quotient obtained by dividing the number of shares of LTX Common Stock outstanding immediately prior to the Effective Time (treating for this purpose as outstanding only those shares of LTX Common Stock that are actually issued and outstanding immediately prior to the Effective Time) by 0.4998, and (y) the number of shares of LTX Common Stock outstanding immediately prior to the Effective Time (treating for this purpose as outstanding only those shares of LTX Common Stock that are actually issued

and outstanding immediately prior to the Effective Time), by (B) that number of shares of Credence Common Stock outstanding immediately prior to the Effective Time, other than any shares of Credence Common Stock to be cancelled pursuant to Section 1.6(b) (treating for this purpose as outstanding only those shares of Credence Common Stock that are actually issued and outstanding immediately prior to the Effective Time) (the “Exchange Ratio”), upon surrender of the certificate representing, immediately prior to the Effective Time, such share of Credence Common Stock (or surrender of a Book Entry Share (as defined in Section 1.7(c)) in the manner provided in Section 1.7 (or in the case of a lost, stolen or destroyed certificate, upon delivery of an affidavit (and bond, if required) in the manner provided in Section 1.9). The parties acknowledge that it is their intention that the Exchange Ratio will cause the holders of outstanding shares of Credence Common Stock immediately prior to the Effective Time to hold a majority of the total outstanding shares of LTX Common Stock immediately following the Effective Time.

(b) Cancellation of Treasury and LTX Owned Stock. Each share of Credence Common Stock held by Credence or LTX, or any direct or indirect subsidiary of Credence or LTX, immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof.

(c) Capital Stock of Merger Sub. Each share of common stock, par value $0.001 per share, of Merger Sub (the “Merger Sub Common Stock”) issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable share of common stock, par value $0.001 per share, of the Surviving Corporation (the “Surviving Corporation Common Stock”). Each certificate evidencing ownership of shares of Merger Sub Common Stock shall evidence ownership of such shares of Surviving Corporation Common Stock.

(d) Stock Options; Stock-Based Awards; Employee Stock Purchase Plan. All Credence Options (as defined in Section 2.2(c)) outstanding under each Credence Stock Plan (as defined in Section 2.2(c)) shall be assumed by LTX in accordance with Sections 5.9(a) and 5.9(b). Credence Restricted Stock and Credence Restricted Stock Units (each as defined in Section 2.2(b)) under Credence Stock Plans shall be treated as set forth in Sections 5.9(c) and 5.9(d), respectively. Rights outstanding under Credence’s 1994 Employee Stock Purchase Plan (the “Credence Purchase Plan”) shall be treated as set forth in Section 5.9(e).

(e) Fractional Shares. No fraction of a share of LTX Common Stock will be issued by virtue of the Merger, but in lieu thereof each holder of record of shares of Credence Common Stock who would otherwise be entitled to receive a fraction of a share of LTX Common Stock (after aggregating all fractional shares of LTX Common Stock that otherwise would be received by such holder of record) shall, upon surrender of such holder’s Certificate(s) (as defined in Section 1.7(c)), receive an amount of cash (rounded to the nearest whole cent), without interest, equal to the product of: (i) such fraction, multiplied by (ii) the average closing sale price at the 4:00 p.m., Eastern time, end of regular trading hours of one share of LTX Common Stock for the 10 most recent trading days that LTX Common Stock has traded ending on the trading day one day prior to the Effective Time, as reported on The Nasdaq Stock Market LLC’s Global Market (“Nasdaq”).

(f) Conversion of Debt. Credence’s 3.5% Convertible Notes due 2010 (the “Credence Convertible Notes”) shall remain outstanding as notes of Credence; however in lieu of being convertible into shares of Credence Common Stock, following the Effective Time, LTX shall enter into a supplemental indenture to the Indenture, dated as of December 20, 2006, relating to the Credence Convertible Notes (the “Indenture”) with the trustee under the Indenture pursuant to which the Credence Convertible Notes shall become convertible into LTX Common Stock at a conversion ratio equal to the conversion ratio in effect immediately prior to the Effective Time multiplied by the Exchange Ratio.

(g) Adjustments to Exchange Ratio. The Exchange Ratio shall be adjusted to reflect fully the appropriate economic effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into LTX Common Stock or Credence Common Stock), extraordinary cash dividend, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to LTX Common Stock or Credence Common Stock occurring or having a record date on or after the date hereof and prior to the Effective Time; provided, however, that nothing in this

Section 1.6(g) shall be construed as providing consent to any action or event pursuant to, or waiving any of the provisions of, Sections 4.1 or 4.2 of this Agreement.

1.7 Surrender of Certificates.

(a) Exchange Agent. Prior to the Effective Time, LTX shall appoint Computershare Trust Company, N.A. or another institution reasonably satisfactory to Credence to act as the exchange agent (the “Exchange Agent”) hereunder for the purpose of distributing the LTX Common Stock and other cash amounts contemplated by this Article I to the holders of Credence Common Stock.

(b) LTX to Provide Common Stock. Promptly after the Effective Time, LTX shall make available to the Exchange Agent for exchange in accordance with this Article I the shares of LTX Common Stock issuable pursuant to Section 1.6(a) in exchange for outstanding shares of Credence Common Stock. In addition, LTX shall make available to the Exchange Agent as necessary from time to time after the Effective Time, cash in an amount sufficient for payment in lieu of fractional shares pursuant to Section 1.6(e) and any dividends or distributions to which holders of shares of Credence Common Stock may be entitled pursuant to Section 1.7(d). Any cash and LTX Common Stock deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.”

(c) Exchange Procedures. As soon as reasonably practicable after the Effective Time, LTX shall cause the Exchange Agent to mail to each holder of record (as of the Effective Time) of a certificate or certificates (the “Certificates”), which immediately prior to the Effective Time represented outstanding shares of Credence Common Stock, or non-certificated shares of Credence Common Stock represented by book entry (“Book Entry Shares”) whose shares were converted into the right to receive shares of LTX Common Stock pursuant to Section 1.6(a), cash in lieu of any fractional shares pursuant to Section 1.6(e) and any dividends or other distributions pursuant to Section 1.7(d): (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates or Book Entry Shares to the Exchange Agent) and shall otherwise be in customary form and (ii) instructions for effecting the surrender of the Certificates or Book Entry Shares in exchange for certificates representing whole shares of LTX Common Stock, cash in lieu of any fractional shares pursuant to Section 1.6(e) and any dividends or other distributions pursuant to Section 1.7(d). Upon surrender of Certificates or Book Entry Shares for cancellation to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto and such other documents as may reasonably be required by the Exchange Agent, the holder of record of such Certificates or Book Entry Shares shall be entitled to receive in exchange therefor the number of whole shares of LTX Common Stock (after taking into account all Certificates and Book Entry Shares surrendered by such holder of record) to which such holder is entitled pursuant to Section 1.6(a) (which, at the election of LTX, may be in uncertificated book entry form unless a physical certificate is requested by the holder of record or is otherwise required by applicable Legal Requirements (as defined in Section 2.2(d)), a cash payment in lieu of fractional shares which such holder has the right to receive pursuant to Section 1.6(e) and a cash payment for any dividends or distributions payable pursuant to Section 1.7(d), and the Certificates and Book Entry Shares so surrendered shall forthwith be canceled. Until so surrendered, outstanding Certificates or Book Entry Shares will be deemed from and after the Effective Time, for all corporate purposes, to evidence only the right to receive the number of full shares of LTX Common Stock into which such shares of Credence Common Stock shall have been converted and the right to receive an amount in cash in lieu of the issuance of any fractional shares in accordance with Section 1.6(e) and any dividends or distributions payable pursuant to Section 1.7(d).

(d) Distributions With Respect to Unexchanged Shares. No dividends or other distributions declared or made after the date hereof with respect to LTX Common Stock with a record date after the Effective Time and no payment in lieu of fractional shares pursuant to Section 1.6(e) will be paid to the holders of any unsurrendered Certificates or Book Entry Shares with respect to the shares of Credence Common Stock formerly represented thereby until the holders of record of such Certificates shall surrender such Certificates or Book Entry Shares in accordance with this Section 1.7. Subject to applicable Legal Requirements,

following surrender of any such Certificates or Book Entry Shares, the Exchange Agent shall deliver to the record holders thereof, without interest (i) promptly after such surrender, the number of whole shares of LTX Common Stock issued in exchange therefor along with payment in lieu of fractional shares pursuant to Section 1.6(e) and the amount of any such dividends or other distributions with a record date after the Effective Time and theretofore paid with respect to such whole shares of LTX Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time and a payment date subsequent to such surrender payable with respect to such whole shares of LTX Common Stock.

(e) Transfers of Ownership. If shares of LTX Common Stock are to be issued in a name other than that in which the Certificates or Book Entry Shares surrendered in exchange therefor are registered, it will be a condition of the issuance thereof that the Certificates or Book Entry Shares so surrendered will be properly endorsed and otherwise in proper form for transfer and that the Persons (as defined in Section 8.3(d)) requesting such exchange will have paid to LTX or any agent designated by it any transfer or other Taxes (as defined in Section 2.6(a)) required by reason of the issuance of shares of LTX Common Stock in any name other than that of the registered holder of the Certificates or Book Entry Shares surrendered, or established to the reasonable satisfaction of LTX or any agent designated by it that such Tax has been paid or is not payable.

(f) Withholding Rights. Each of LTX, the Exchange Agent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Credence Common Stock such amounts as may be required to be deducted or withheld therefrom under the Code or under any provision of state, local or foreign Tax law or under any other applicable Legal Requirements, and to collect IRS Forms W-8 or W-9, as applicable, or similar information from the recipients of payments hereunder.

(h) Effect of Transaction. The execution of this Agreement and the consummation of the transactions contemplated hereby will not (either alone or upon the occurrence of any additional or subsequent events) constitute an event under any Credence Benefit Plan or Credence Employee Agreement that will or may result in any material payment (whether of severance pay or otherwise), acceleration of any material payment, forgiveness of material indebtedness, vesting, distribution, material increase in benefits or obligation to fund benefits with respect to any Credence Employee. No payment or benefit which will or may be made in connection with the transactions contemplated by this Agreement by Credence or any ERISA Affiliate with respect to any Credence Employee or any other “disqualified individual” (as defined in Code Section 280G and the regulations thereunder) will be characterized as a “parachute payment,” within the meaning of Section 280G(b)(2) of the Code.

Each LTX Benefit Plan, including any material amendments thereto, that is capable of Approval has received such Approval or there remains a period of time in which to obtain such Approval retroactive to the date of any material amendment that has not previously received such Approval, except for the lack of such Approvals which, individually or in the aggregate, has not resulted in and would not reasonably be expected to result in material liability to LTX and its Controlled Group Affiliates, taken as a whole. Except as required by Legal Requirements, no condition exists that would prevent LTX or Credence from terminating or amending any LTX Benefit Plan at any time for any reason without material liability to LTX and its ERISA Affiliates, taken as a whole (other than ordinary administration expenses or routine claims for benefits).

(iii) No material written representation or commitment with respect to any material aspect of any LTX Benefit Plan has been made to an LTX Employee by an authorized LTX Employee that is not materially in accordance with the written or otherwise preexisting terms and provisions of such LTX Benefit Plans that would reasonably be expected to result in material liability to LTX and its ERISA Affiliates, taken as a whole. Neither LTX nor any of its Subsidiaries has entered into any agreement, arrangement or understanding, whether written or oral, with any trade union, works council or other LTX Employee representative body or any material number or category of its LTX Employees which would prevent, restrict or materially impede the implementation of any lay-off, redundancy, severance or similar program within its or their respective workforces (or any part of them).

(e) Plan Funding. With respect to LTX Benefit Plans, there are no material benefit obligations for which required contributions have not been made or accrued to the extent required by GAAP and there are no material benefit obligations which have not been accounted for by reserves, or otherwise properly footnoted in accordance with the requirements of GAAP, on the financial statements of LTX. The assets of each LTX Benefit Plan which is funded are reported at their fair market value on the books and records of such LTX Benefit Plan.

(h) Effect of Transaction. The execution of this Agreement and the consummation of the transactions contemplated hereby will not (either alone or upon the occurrence of any additional or subsequent events) constitute an event under any LTX Benefit Plan or LTX Employee Agreement that will or may result in any material payment (whether of severance pay or otherwise), acceleration of any material payment, forgiveness of material indebtedness, vesting, distribution, material increase in benefits or obligation to fund benefits with respect to any LTX Employee. No payment or benefit which will or may be made in connection with the transactions contemplated by this Agreement by LTX or any ERISA Affiliate with respect to any LTX Employee or any other “disqualified individual” (as defined in Code Section 280G and the regulations thereunder) will be characterized as a “parachute payment,” within the meaning of Section 280G(b)(2) of the Code. There is no contract, agreement, plan or arrangement to which LTX or any ERISA Affiliate is a party or by which it is bound to compensate any LTX Employee for excise taxes paid pursuant to Section 4999 of the Code. Section 3.12(h) of the LTX Disclosure Schedule lists all persons who LTX reasonably believes are “disqualified individuals” (within the meaning of Section 280G of the Code and the regulations promulgated thereunder) as determined as of the date hereof.

(i) Section 409A.

No nonqualified deferred compensation plan has been “materially modified” (within the meaning of IRS Notice 2005-1) at any time after October 3, 2004. No stock option or other right to acquire LTX Common Stock or other equity of LTX has any feature for the deferral of compensation other than the deferral of recognition of income until the later of exercise or disposition of such option or rights.

(j) Stock Option Grant Practices. LTX’s past and current stock option grant practices (i) complied and comply with all applicable LTX Stock Plans, stock exchange rules and applicable Legal Requirements, (ii) have been fairly presented in accordance with GAAP in the LTX Financials, and (iii) have resulted only in exercise prices that correspond to the fair market value on the date that the grants were actually authorized under applicable Legal Requirements, in each case except for any such failures, individually or in the aggregate, that have not had and would not reasonably be expected to have a Material Adverse Effect on LTX and its Subsidiaries, taken as a whole. As of the date of this Agreement, LTX has no ongoing internal review of any past or current stock option practice, and LTX is not aware of the existence of any reports on any such reviews completed since January 1, 2005.

(k) Labor.

Except as set forth in the LTX Leases or as disclosed in the LTX Disclosure Schedule, no party has a right to occupy any of the premises subject to a LTX Lease (“LTX Leased Property”) except for LTX or its Subsidiaries. LTX has made available to LTX a true and complete copy of each LTX Lease. All such LTX Leases are valid and in full force and effect against LTX or any Subsidiary of LTX party thereto and, to the Knowledge of LTX, each other party thereto, except that such enforceability (i) may be limited by applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws affecting or relating to creditors’ rights generally and (ii) is subject to general principles of equity, and, with respect to LTX or any of its Subsidiaries, under any of such leases, no rental payments are past due and there is no existing default or event of default (or event which with notice or lapse of time, or both, would constitute a default), except, individually or in the aggregate, as has not had and would not reasonable be expected to have a Material Adverse Effect on LTX and its Subsidiaries, taken as a whole.

(b) Properties. Section 3.13(b) of the LTX Disclosure Schedule sets forth a list of all real property owned by LTX or any of its Subsidiaries (the “LTX Owned Property” and collectively with LTX Leased Property, the “LTX Real Property”).

acquired such parcel of property, and copies of all title insurance policies, opinions, abstracts and surveys in the possession of LTX or any of its Subsidiaries relating thereto. There are no pending or, to the Knowledge of LTX, threatened condemnation or eminent domain actions or proceedings, or any special assessments or other activities of any public or quasi-public body that are reasonably likely to materially adversely affect LTX’s title to LTX Real Property. To the Knowledge of LTX, there are no facts or conditions which would, in the aggregate, reasonably be expected to have a material and adverse effect on the transferability, financability, ownership, leasing, use, development, occupancy or operation of any such real property. Neither LTX nor any Subsidiary has received any written notice from any insurance company of any defects or inadequacies in any LTX Real Property or any part thereof which would reasonably be expected to materially and adversely affect the insurability of such property or the premiums for the insurance thereof, nor has any written notice been given by any insurer of any such property requesting the performance of any repairs, alterations or other work with which compliance has not been made. There are no leases, subleases, licenses or agreements, written or oral, granting to any party or parties (other than LTX or any of its Subsidiaries) the right of use or occupancy of any portion of the LTX Real Property. There are no outstanding options or rights of first refusal to purchase the LTX Real Property or any portion thereof or interest therein.

(c) Valid Title. LTX and each of its Subsidiaries has good and valid title to, or, in the case of leased properties and assets, valid leasehold interests in, all of its tangible properties and assets, real, personal and mixed, used or held for use in its business that are material to LTX and its Subsidiaries, taken as a whole, free and clear of any Liens, except for (i) Liens imposed by law in respect of obligations not yet due which are owed in respect of Taxes or (ii) Liens which are not material in character, amount or extent, and which do not materially detract from the value, or materially interfere with the present use, of the property subject thereto or affected thereby.

A signed copy of such opinion will be provided to Credence as promptly as practicable following receipt thereof by LTX.

3.20 Rights Plan. LTX has taken all action so that (a) Credence shall not be an “Acquiring Person” under the LTX Rights Agreement and (b) the entering into of this Agreement and the Merger and the consummation of the other transactions contemplated hereby will not result in the grant of any rights to any Person under the LTX Rights Agreement or enable or require the LTX Rights to be exercised, distributed or triggered as a result thereof.

3.21 Shell Company Status. Neither LTX nor Merger Sub is a “shell company,” other than a “business combination related shell company,” as those terms are defined in Rule 405 promulgated under the Securities Act.

(i) In response to the receipt of a Superior Offer that has not been withdrawn, the Board of Directors of LTX or Credence, as the case may be, may withhold, withdraw, amend or modify its recommendation in favor of, in the case of LTX, the Share Issuance and the Charter Amendment, and in the case of Credence, adoption of this Agreement, in each case, in a manner adverse to the other party, and in the case of a Superior Offer that is a tender or exchange offer, recommend that its stockholders accept the tender or exchange offer (any of the foregoing actions, whether by a Board of Directors or a committee thereof, a “Change of Recommendation”), if all of the following conditions in clauses (1) through (5) are met:

(1) Its Stockholders’ Meeting has not occurred;

(2) It shall have (A) provided the other party hereto with written notice of its intention to effect a Change of Recommendation (a “Change of Recommendation Notice”) at least three business days prior to effecting a Change of Recommendation that relates to (i) a Superior Offer

(4) Its Board of Directors has concluded in good faith, following consultation with its outside legal counsel, that, in light of such Superior Offer and after taking into consideration the Matching Bid, if any, the failure of the Board of Directors to effect a Change of Recommendation would be reasonably likely to result in a breach of its fiduciary duties under applicable Legal Requirements; and

(5) It shall not have materially breached any of the provisions set forth in Section 5.2 or this Section 5.3 (including Section 5.3(b)).

Neither LTX nor Credence shall take or agree to take any action identified in the immediately preceding sentence without the prior written consent of the other.

5.7 Notification of Certain Matters.

(a) By Credence. Credence shall give prompt notice to LTX of any representation or warranty made by it contained in this Agreement becoming untrue or inaccurate, or any failure of Credence to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in each case, such that the conditions set forth in Section 6.3(a) or 6.3(b) would not be satisfied.

(b) By LTX. LTX and Merger Sub shall give prompt notice to Credence of any representation or warranty made by it contained in this Agreement becoming untrue or inaccurate, or any failure of LTX to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in each case, such that the conditions set forth in Section 6.2(a) or 6.2(b) would not be satisfied.

5.9 Equity Awards and Employee Benefits.

(a) Assumption of Credence 2005 Stock Incentive Plan and Stock Options. At the Effective Time, (i) Credence’s 2005 Stock Incentive Plan and (ii) each then outstanding Credence Option, whether or not exercisable at the Effective Time and regardless of the respective exercise prices thereof, will be assumed by LTX. Each Credence Option so assumed by LTX under this Agreement will continue to have, and be subject to, the same terms and conditions set forth in the applicable Credence Option (including any applicable stock option agreement or other document evidencing such Credence Option) immediately prior to the Effective Time (including any repurchase rights or vesting provisions), except that (i) each Credence Option will be exercisable (or will become exercisable in accordance with its terms) for that number of whole shares of LTX Common Stock equal to the product of the number of shares of Credence Common

Stock that were issuable upon exercise of such Credence Option immediately prior to the Effective Time multiplied by the Exchange Ratio, rounded down to the nearest whole number of shares of LTX Common Stock and (ii) the per share exercise price for the shares of LTX Common Stock issuable upon exercise of such assumed Credence Option will be equal to the quotient determined by dividing the exercise price per share of Credence Common Stock at which such Credence Option was exercisable immediately prior to the Effective Time by the Exchange Ratio, rounded up to the nearest whole cent. Each assumed Credence Option shall be vested immediately following the Effective Time as to the same percentage of the total number of shares subject thereto as it was vested as to immediately prior to the Effective Time, except to the extent such Credence Option by its terms in effect prior to the date hereof and not otherwise amended prior to the Effective Time provides for acceleration of vesting. Promptly following the Closing Date, LTX will deliver to each Person who holds an assumed Credence Option a document evidencing the foregoing assumption of such Credence Option by LTX. Credence shall take all steps necessary to cause the foregoing provisions of this Section 5.9(a) to occur.

(b) Incentive Stock Options. The conversion of Credence Options provided for in Section 5.9(a) with respect to any options which are intended to be “incentive stock options” (as defined in Section 422 of the Code) shall be effected in a manner consistent with Section 424(a) of the Code.

(c) Unvested Credence Restricted Stock. At the Effective Time, any shares of LTX Common Stock issued in accordance with Section 1.6(a) with respect to any unvested shares of Credence Restricted Stock outstanding immediately prior to the Effective Time shall remain subject to the same terms, restrictions and vesting schedule as in effect immediately prior to the Effective Time, except to the extent by their terms such unvested shares of Credence Restricted Stock vest at the Effective Time. Credence shall not take or permit any action which would accelerate vesting of any unvested shares, except to the extent required by their terms as in effect on the date hereof. Copies of the relevant agreements governing such Credence Restricted Stock and the vesting thereof have been provided to LTX. All outstanding rights which Credence may hold immediately prior to the Effective Time to repurchase unvested shares of Credence Restricted Stock shall be assigned to LTX in the Merger and shall thereafter be exercisable by LTX upon the same terms and conditions in effect immediately prior to the Effective Time, except that the shares purchasable pursuant to such rights and the purchase price payable per share shall be appropriately adjusted to reflect the Exchange Ratio. Credence shall take all steps necessary to cause the foregoing provisions of this Section 5.9(c) to occur.

(d) Credence Restricted Stock Units. At the Effective Time, each Credence Restricted Stock Unit then outstanding shall be assumed by LTX. Subject to, and in accordance with, the terms of the applicable Credence Stock Plan and any applicable award or other agreement, each Credence Restricted Stock Unit shall be converted into the right to receive the number of shares of LTX Common Stock (or an amount in respect thereof for cash settled Credence Restricted Stock Unit) equal to the number of shares of Credence Common Stock subject to the Credence Restricted Stock Unit multiplied by the Exchange Ratio (rounded down to the nearest whole number of shares of LTX Common Stock). Each Credence Restricted Stock Unit shall have the same terms and conditions as were in effect immediately prior to the Effective Time. Credence shall not take or permit any action which would accelerate vesting of any Credence Restricted Stock Unit, except to the extent required by their terms as in effect on the date hereof. Copies of the relevant agreements governing such Credence Restricted Stock Unit and the vesting thereof have been provided to LTX. All outstanding rights which Credence may hold immediately prior to the Effective Time to the forfeiture of shares of Credence Common Stock subject to the Credence Restricted Stock Unit shall be assigned to LTX in the Merger and shall thereafter be held by LTX upon the same terms and conditions in effect immediately prior to the Effective Time, except that the shares forfeitable pursuant to such rights shall be appropriately adjusted to reflect the Exchange Ratio. Credence shall take all steps necessary to cause the foregoing provisions of this Section 5.9(d) to occur.

(e) Service Recognition. From and after the Effective Time, LTX will, or will cause the Surviving Corporation to, recognize the prior service with Credence or its Subsidiaries of each employee of Credence or its Subsidiaries as of the Effective Time (the “Credence Current Employees”) in connection with all

employee benefit plans, programs or policies (including vacation) of LTX or its affiliates in which Credence Current Employees are eligible to participate following the Effective Time, for purposes of eligibility and vesting (but not for purposes of benefit accruals or benefit amounts under any defined benefit pension plan or to the extent that such recognition would result in duplication of benefits). From and after the Effective Time, LTX or the Surviving Corporation shall provide Credence Current Employees health and welfare benefits pursuant to employee benefit plans, programs, policies or arrangements maintained by LTX or any Subsidiary of LTX providing coverage and benefits which are no less favorable than those provided to employees of LTX in positions comparable to positions held by Credence Current Employees with LTX or its Subsidiaries. From and after the Effective Time, LTX will, or will cause the Surviving Corporation, to cause any pre-existing conditions or limitations and eligibility waiting periods (to the extent that such waiting periods would be inapplicable, taking into account service with Credence) under any group health plans of LTX or its affiliates to be waived with respect to Credence Current Employees and their dependents and to recognize for purposes of annual deductible and out-of-pocket limits under its medical and dental plans, deductible, co-pay, and out-of-pocket expenses paid by Credence Current Employees in the calendar year in which the Effective Time occurs.

(f) Termination of Credence Purchase Plan. Prior to the Effective Time, Credence shall take all action that may be necessary to cause all participants’ rights under all current offering periods under Credence Purchase Plan to terminate on or prior to the day immediately preceding the Closing Date and to allow all participants to purchase prior to the Effective Time shares of Credence Common Stock based on any purchase rights accrued as of such date as provided by the terms of the Credence Purchase Plan. To the extent shares of Credence Common Stock are not purchased as provide in the preceding sentence, on the day immediately preceding the Closing Date all accumulated payroll deductions allocated to each participant’s account under the Credence Purchase Plan shall be returned to each participant as provided by the terms of the Credence Purchase Plan and no shares of Credence Common Stock shall be purchased under the Credence Purchase Plan for such final offering period. As of the close of business on the day immediately prior to the Closing Date, Credence shall have terminated the Credence Purchase Plan and provided such notice of termination as may be required by the terms of the Credence Purchase Plan. The form and substance of any such notice regarding the Credence Purchase Plan termination shall be subject to the review and approval of LTX, which shall not be unreasonably withheld, conditioned or delayed.

(g) Termination of 401(k) Plans. Unless otherwise requested by LTX in writing prior to the Effective Time, Credence shall cause to be adopted prior to the Closing Date resolutions of Credence’s Board of Directors to cease all contributions to any and all 401(k) plans maintained or sponsored by Credence or any of its Subsidiaries (collectively, the “401(k) Plans”), and to terminate the 401(k) Plans, on the day preceding the Closing Date. The form and substance of such resolutions shall be subject to the review and approval of LTX, which shall not be unreasonably withheld, conditioned or delayed. Credence shall deliver to LTX an executed copy of such resolutions as soon as practicable following their adoption by Credence’s Board of Directors and shall fully comply with such resolutions.

5.10 Indemnification.

(a) Indemnity. From and after the Effective Time, LTX shall, and shall cause the Surviving Corporation to, jointly and severally, indemnify and hold harmless each Person who is now, or has been at any time prior to the date hereof, or who becomes prior to the Effective Time, a director or officer of Credence or any of its Subsidiaries or any predecessor entity (the “Indemnified Parties”), against all claims, losses, liabilities, damages, judgments, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements, incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to the fact that the Indemnified Party is or was an officer or director of Credence or any of its Subsidiaries, whether asserted or claimed prior to, at or after the Effective Time, according to the indemnification provisions of Credence’s certificate of incorporation and bylaws as in effect on the date of this Agreement. From and after the Effective Time, subject to applicable Legal Requirements, LTX shall, and shall cause the Surviving Corporation to, fulfill

and honor in all respects the obligations of Credence pursuant to any indemnification agreement existing prior to the date hereof between Credence and any Indemnified Party, true and correct copies of which have been provided to LTX prior to the date hereof. The certificate of incorporation and bylaws of the Surviving Corporation will contain provisions with respect to exculpation, advancement of expenses and indemnification that are at least as favorable to the Indemnified Parties as those contained in the certificate of incorporation and bylaws of Credence as in effect on the date hereof, which provisions will not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would adversely affect the rights thereunder of Indemnified Parties, unless such modification is required by law.

(b) Insurance. For a period of six years after the Effective Time, LTX shall cause the Surviving Corporation to maintain in effect Credence’s current directors’ and officers’ liability insurance (the “D&O Insurance”) covering those Persons who are covered by the D&O Insurance as of the date hereof, a complete and accurate copy of which has been provided to LTX, for events occurring at or prior to the Effective Time (including for acts or omissions occurring in connection with this Agreement and the consummation of the transactions contemplated herby, to the extent that such acts or omissions are covered by the D&O Insurance) on terms and in amounts at least as favorable to such Persons as provided in the D&O Insurance; provided, however, that in no event shall the Surviving Corporation be required to expend in any one year in excess of 200% of the annual premium currently paid by Credence for such coverage (which Credence represents and warrants to be as set forth in Section 5.10(b) of the Credence Disclosure Schedule) (and to the extent the annual premium would exceed 200% of the annual premium currently paid by Credence for such coverage, LTX shall cause the Surviving Corporation to maintain the maximum amount of coverage as is reasonably available for such 200% of such annual premium). To the extent that a six year “tail” policy to extend Credence’s existing D&O Insurance is available at or prior to the Closing such that the lump sum payment for such coverage does not exceed 250% of the annual premium currently paid by Credence for such coverage, Credence may, at its option, obtain such “tail” policy. In the event that Credence purchases such “tail” policy prior to the Closing, LTX shall not take any action to cause the “tail” policy to cease to be in full force and effect and such “tail” policy shall satisfy LTX’s obligation under this Section 5.10.

(c) Third–Party Beneficiaries. This Section 5.10 is intended to be for the benefit of, and shall be enforceable by, the Indemnified Parties and their heirs and personal representatives and shall be binding on LTX and the Surviving Corporation and its successors and assigns. In the event LTX or the Surviving Corporation or its successor or assign (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each case, proper provision shall be made so that the successor and assign of LTX or the Surviving Corporation, as the case may be, honors the obligations set forth with respect to LTX or the Surviving Corporation, as the case may be, in this Section 5.10.

5.11 Form S-8. LTX agrees to file with the SEC, no later than ten business days after the Closing Date, a registration statement on Form S-8 (or any successor form) relating to the shares of LTX Common Stock issuable with respect to assumed Credence Options and issuable upon settlement of Credence Restricted Stock Units eligible for registration on Form S-8 and shall use commercially reasonable efforts to maintain the effectiveness of such registration statement thereafter for so long as any of such options or other rights remain outstanding.

5.12 Treatment as Reorganization.

(a) None of LTX, Merger Sub or Credence shall, and they shall not permit any of their respective Subsidiaries to, take any action (or fail to take any action) prior to or following the Closing that would reasonably be expected to cause the Merger to fail to qualify as a reorganization with the meaning of Section 368(a) of the Code.

(b) LTX, on its behalf and on behalf of Merger Sub, and Credence shall execute and deliver to each of Wilmer Cutler Pickering Hale and Dorr LLP, counsel to LTX and Merger Sub (“WilmerHale”), and Morrison & Foerster LLP, counsel to Credence (“MoFo”), tax representation letters in customary form at such time or times as reasonably requested by each such law firm in connection with its delivery of the tax opinions referred to in Section 6.1(f) and tax opinions satisfying the requirements of Item 601 of Regulation S-K promulgated under the Securities Act. In rendering such opinions, each of such counsel shall be entitled to rely on the tax representation letters referred to in this Section 5.12(b).

Prior to the time that LTX takes the actions specified in clause (ii) of the preceding sentence, the Board of Directors of Credence shall approve the nomination for election and the election to the Board of Directors of LTX of each of the persons identified in such clause (ii).

(b) Credence shall take all action necessary to cause the number of directors that comprise the full Board of Directors of Credence to be fixed at seven and to cause one member of LTX’s Board of Directors as of the date hereof designated by LTX (who shall be one of the four members of LTX’s Board of Directors designated pursuant to Section 5.13(a)(ii)(C) above) to be appointed to the Board of Directors of Credence not more than three and not less than one day prior to the Closing Date.

(c) On or prior to the Effective Time, the Board of Directors of LTX shall take all actions necessary to cause (i) LTX’s Chief Executive Officer to continue as Chief Executive Officer of LTX from and after the Effective Time, (ii) LTX’s Chief Financial Officer to continue as Chief Financial Officer of LTX from and after the Effective Time and (iii) Credence ‘s Chief Executive Officer to be appointed as the Executive Chairman of the Board of LTX from and after the Effective Time, each to hold office until his successor is elected and qualified or otherwise in accordance with the LTX Charter Documents.

5.16 Reservation of LTX Common Stock. Effective at or prior to the Effective Time, LTX shall reserve (free from preemptive rights) out of its reserved but unissued or treasury shares of LTX Common Stock, for the

TERMINATION, AMENDMENT AND WAIVER

7.1 Termination. This Agreement may be terminated at any time prior to the Effective Time, by action taken or authorized by the Board of Directors of the terminating party or parties, and except as provided below, whether before or after the requisite approvals of the stockholders of Credence or LTX:

(a) by mutual written consent duly authorized by the Boards of Directors of LTX and Credence;

(b) by either Credence or LTX if the Merger shall not have been consummated by January 20, 2009, (the “Outside Date”); provided, however, that the right to terminate this Agreement under this Section 7.1(b) shall not be available to any party whose action or failure to act has been a principal cause of or resulted in the failure of the Merger to occur on or before such date and such action or failure to act constitutes a material breach of this Agreement;

(c) by either Credence or LTX if a Governmental Entity shall have issued an order, decree or ruling or taken any other action (including the failure to have taken an action), in any case having the effect of permanently restraining, enjoining or otherwise prohibiting the Merger, which order, decree, ruling or other action is final and nonappealable;

(d) by either Credence or LTX if the required approval of the stockholders of Credence contemplated by this Agreement shall not have been obtained by reason of the failure to obtain the required vote at a meeting of Credence stockholders duly convened therefor or at any adjournment or postponement thereof at which the applicable vote is taken;

(e) by either Credence or LTX if the required approval of the stockholders of LTX contemplated by this Agreement shall not have been obtained by reason of the failure to obtain the required vote at a meeting of the LTX stockholders duly convened therefor or at any adjournment or postponement thereof at which the applicable vote is taken;

Credence may not terminate this Agreement under this Section 7.1(h) prior to 30 days following the receipt of written notice from Credence to LTX of such inaccuracy or breach; provided further that LTX exercises commercially reasonable efforts to cure such breach through such 30 day period (it being understood that Credence may not terminate this Agreement pursuant to this Section 7.1(h) if it shall have materially breached this Agreement or if such inaccuracy or breach by LTX is cured in all material respects within such 30 day period); and

In the event of the termination of this Agreement as provided in Section 7.1, this Agreement shall be of no further force or effect, except (a) as set forth in Section 5.4(a), this Section 7.2, Section 7.3 and Article VIII, each of which shall survive the termination of this Agreement, and (b) nothing herein shall relieve any party from liability for damages for fraud in connection with, or any intentional or willful breach of, this Agreement. No termination of this Agreement shall affect the obligations of the parties contained in the Confidentiality Agreement, which agreement shall survive termination of this Agreement in accordance with its terms.

7.3 Fees and Expenses.

(a) General. Except as set forth in this Section 7.3, all fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses

whether or not the Merger is consummated; provided, however, that LTX and Credence shall share equally all fees and expenses, other than attorneys’ and accountants’ fees and expenses (which shall be paid by the party incurring such fee or expense), incurred in relation to (i) the printing and filing with the SEC of the Proxy Statement/Prospectus (including any preliminary materials related thereto) and the Registration Statement (including financial statements and exhibits) and any amendments or supplements thereto and (ii) the filing fee for the Notification and Report Forms filed with the FTC and DOJ under the HSR Act and premerger notification and reports forms under similar applicable Legal Requirements of other jurisdictions, in each case pursuant to Section 5.6(a).

(b) Payments.

(1) by LTX pursuant to Section 7.1(f), then Credence shall promptly, but in no event later than two business days after the date of such termination, pay LTX a fee equal to $6,750,000 in immediately available funds (the “Credence Termination Fee”); or

(2)(x) by LTX or Credence pursuant to Section 7.1(b) or Section 7.1(d) and (y) following the date hereof and prior to the termination of this Agreement pursuant to Section 7.1(b) or Section 7.1(d), as the case may be, any Acquisition Proposal with respect to Credence shall have been made known to Credence or publicly disclosed and, in either case, not withdrawn and (A) within 12 months following the termination of this Agreement an Acquisition (as defined in Section 7.3(b)(iv)) of Credence is consummated or (B) within 12 months following the termination of this Agreement Credence enters into an agreement providing for an Acquisition of Credence, then Credence shall promptly pay LTX the Credence Termination Fee, but in no event later than two business days after the first to occur of (A) or (B) (it being understood that only one Credence Termination Fee shall be payable in the event that (A) and (B) both occur).

(ii) Payment by LTX. In the event that this Agreement is terminated

(iii) Interest and Costs; Other Remedies. Each of LTX and Credence acknowledges that the agreements contained in this Section 7.3(b) are integral parts of the transactions contemplated by this Agreement, and that, without these agreements, the other party hereto would not enter into this Agreement. Accordingly, if LTX or Credence, as the case may be, fails to pay in a timely manner the amounts due pursuant to this Section 7.3(b), and, in order to obtain such payment, the other party hereto makes a claim that results in a judgment against the party failing to pay for the amounts set forth in this Section 7.3(b), the party so failing to pay shall pay to the other party hereto its reasonable costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amounts set forth in this Section 7.3(b) from the date such payment becomes due pursuant to this Section 7.3(b) to the date paid at the prime rate of Citibank, N.A. in effect on the date such payment was required to be made. Payment of the fees described in this Section 7.3(b) shall not

relieve any party from any liability incurred in the event of breach of this Agreement to the extent provided in clause (b) of Section 7.2 hereof.

(iv) Certain Definitions. For the purposes of this Section 7.3(b) only, “Acquisition,” with respect to a party hereto, shall mean the transactions contemplated by an Acquisition Proposal (other than the transactions contemplated by this Agreement); provided, that for the purpose of this definition, the term “Acquisition Proposal” shall have the meaning assigned to such term in Section 5.3(g)(i), except that references to “15%” therein shall be deemed to be references to “50%.”

7.4 Amendment. Subject to applicable Legal Requirements, 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 Agreement and the Merger by the stockholders of LTX and Credence, provided, however, after such approval, no amendment shall be made which by applicable Legal Requirements or in accordance with the rules of any relevant stock exchange requires further approval by such stockholders without such further stockholder approval. This Agreement may not be amended except by execution of an instrument in writing signed on behalf of each of LTX, Merger Sub and Credence.

7.5 Extension; Waiver. At any time prior to the Effective Time, any party hereto, by action taken or authorized by its Board of Directors, may, to the extent legally allowed: (a) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (b) waive any inaccuracies in the representations and warranties made to such party contained herein or in any document delivered pursuant hereto, and (c) waive compliance with any of the agreements or conditions for the benefit of such party 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 an instrument in writing signed on behalf of such party. Delay in exercising any right under this Agreement shall not constitute a waiver of such right.

8.8 Other Remedies. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

(a) This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of law thereof.
