AGREEMENT AND PLAN OF MERGER AND REORGANIZATION

THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION (“Agreement”) is made and entered into as of July 16, 2008, by and among: ON SEMICONDUCTOR, INC., a Delaware corporation (“Parent”); CENTAUR ACQUISITION CORPORATION, a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”); and CATALYST SEMICONDUCTOR, INC., a Delaware corporation (the “Company”). Certain capitalized terms used in this Agreement are defined in EXHIBIT A and other capitalized terms used in this Agreement are defined in the Sections of this Agreement where they first appear.

RECITALS

A. Parent, Merger Sub and the Company intend to effect a merger of Merger Sub into the Company in accordance with this Agreement and the DGCL (the “Merger”). Upon consummation of the Merger, Merger Sub will cease to exist, and the Company will become a wholly owned subsidiary of Parent.

B. The respective Boards of Directors of Parent, Merger Sub and the Company have deemed it advisable and in the best interests of their respective corporations and stockholders that Merger Sub and the Company consummate the Merger provided for herein.

C. For U.S. federal income tax purposes, the parties intend that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”) and intend for this Agreement to constitute a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations.

D. Concurrent with the execution of this Agreement and as a condition to and inducement of Parent’s willingness to enter into this Agreement, the directors and executive officers of the Company set forth on Schedule A are entering into voting undertakings in substantially the form attached as EXHIBIT B (the “Voting Undertakings”).

E. The respective boards of directors of Parent, Merger Sub and the Company have approved this Agreement and approved the Merger.

F. Concurrently with the execution of this Agreement, as a condition and inducement to Parent’s willingness to enter into this Agreement, the chief executive officer of the Company is entering into employment and noncompete agreements with Parent (the “Employment Agreements”).

AGREEMENT

The parties to this Agreement, intending to be legally bound, agree as follows:

SECTION 1: DESCRIPTION OF TRANSACTION.

1.1 Merger of Merger Sub into the Company. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time (as defined in Section 1.3), Merger Sub shall be merged with and into the Company, and the separate existence of Merger Sub shall cease. Following the Effective Time, the Company shall continue as the surviving corporation (the “Surviving Corporation”).

1.2 Effect of the Merger. The Merger shall have the effects set forth in this Agreement and in the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all the property, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

1.3 Closing; Effective Time. The consummation of the transactions contemplated by this Agreement (the “Closing”) shall take place at the offices of DLA Piper US LLP, 2415 East Camelback Road, Suite 700, Phoenix, Arizona 85016, at 10:00 a.m. on a date to be designated by Parent (the “Closing Date”), which shall be no later than the fifth business day after the satisfaction or waiver of the last to be satisfied or waived of the conditions set forth in Section 6 (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions). Subject to the provisions of this Agreement, a certificate of merger satisfying the applicable requirements of the DGCL (the “Certificate of Merger”) shall be duly executed by the Company and, simultaneously with or as soon as practicable following the Closing, filed with the Secretary of State of the State of Delaware (the “Secretary of State”). The Merger shall become effective upon the later of: (a) the date and time of the filing of the Certificate of Merger with the Secretary of State, or (b) such later date and time as may be specified in the Certificate of Merger with the consent of Parent. The date and time the Merger becomes effective is referred to in this Agreement as the “Effective Time.”

1.4 Certificate of Incorporation and Bylaws; Directors and Officers. At the Effective Time:

1.4(a) the Certificate of Incorporation of the Company shall be amended to read in its entirety substantially in the form attached as EXHIBIT C;

1.4(b) the Bylaws of the Company shall be amended and restated to conform to the Bylaws of Merger Sub as in effect immediately prior to the Effective Time; and

1.4(c) the directors and officers of the Surviving Corporation immediately after the Effective Time shall be the respective individuals who are directors and officers of Merger Sub immediately prior to the Effective Time.

1.5 Conversion of Shares.

1.5(a) At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any stockholder of the Company:

(i) any shares of Company Common Stock then held by the Company or any wholly owned Subsidiary of the Company (or held in the Company’s treasury) shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(ii) any shares of Company Common Stock then held by Parent, Merger Sub or any other wholly owned Subsidiary of Parent shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(iii) except as provided in clauses (i) and (ii) above and subject to Sections 1.5(b) and 1.5(c), each share of Company Common Stock then outstanding shall be converted into the right to receive 0.706 of a share of Parent Common Stock; and

(iv) each share of the common stock, $0.001 par value per share, of Merger Sub then outstanding shall be converted into one share of common stock of the Surviving Corporation.

The fraction of a share of Parent Common Stock specified in Section 1.5(a)(iii) (as such fraction may be adjusted in accordance with Section 1.5(b)) is referred to as the “Exchange Ratio.”

1.5(b) If, between the date of this Agreement and the Effective Time, the outstanding shares of Company Common Stock or Parent Common Stock are changed into a different number or class of shares by reason of any stock split, stock dividend, reverse stock split, reclassification, recapitalization or other similar transaction, then the Exchange Ratio shall be appropriately adjusted.

1.5(c) No fractional shares of Parent Common Stock shall be issued in connection with the Merger, and no certificates or scrip for any such fractional shares shall be issued. Any holder of Company Common Stock who would otherwise be entitled to receive a fraction of a share of Parent Common Stock (after aggregating all fractional shares of Parent Common Stock issuable to such holder) shall, in lieu of such fraction of a share and upon surrender of such holder’s Company Stock Certificate(s) (as defined in Section 1.6), be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by the closing price of a share of Parent Common Stock on The NASDAQ Stock Market on the date the Merger becomes effective.

1.6 Closing of the Company’s Transfer Books. At the Effective Time: (a) all holders of certificates representing shares of Company Common Stock that were outstanding immediately prior to the Effective Time shall cease to have any rights as stockholders of the Company other than the right to receive shares of Parent Common Stock (and cash in lieu of any fractional share of Parent Common Stock) as contemplated by Section 1.5; and (b) the stock transfer books of the Company shall be closed with respect to all shares of Company Common Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Company Common Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any shares of Company Common Stock (a “Company Stock Certificate”) is presented to the Exchange Agent (as defined in Section 1.7) or to the Surviving Corporation or Parent, such Company Stock Certificate shall be canceled and shall be exchanged as provided in Section 1.7.

1.7 Exchange of Certificates.

1.7(a) On or prior to the Closing Date, Parent shall select a reputable bank or trust company reasonably satisfactory to the Company to act as exchange agent in the Merger (the “Exchange Agent”). Promptly after the Effective Time, but in no event later than two (2) business days thereafter, Parent shall deposit with the Exchange Agent (i) certificates representing the shares of Parent Common Stock issuable pursuant to this Section 1, and (ii) cash sufficient to make payments in lieu of fractional shares in accordance with Section 1.5(c). The shares of Parent Common Stock and cash amounts so deposited with the Exchange Agent, together with any dividends or distributions received by the Exchange Agent with respect to such shares, are referred to collectively as the “Exchange Fund.”

1.7(b) As soon as reasonably practicable after the Effective Time, but in no event later than two (2) business days thereafter, the Exchange Agent will mail to the record holders of Company Stock Certificates (i) a letter of transmittal in customary form and containing such provisions as Parent, in consultation with the Company, may reasonably specify (including a provision confirming that delivery of Company Stock Certificates shall be effected, and risk of loss and title to Company Stock Certificates shall pass, only upon delivery of such Company Stock Certificates to the Exchange Agent), and (ii) instructions for use in effecting the surrender of Company Stock Certificates in exchange for

certificates representing Parent Common Stock. Upon surrender of a Company Stock Certificate to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Parent, (1) the holder of such Company Stock Certificate shall be entitled to receive in exchange therefor a certificate or evidence of shares in book entry form representing the number of whole shares of Parent Common Stock that such holder has the right to receive pursuant to the provisions of Section 1.5 (and cash in lieu of any fractional share of Parent Common Stock), and (2) the Company Stock Certificate so surrendered shall be canceled. Until surrendered as contemplated by this Section 1.7, each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive shares of Parent Common Stock (and cash in lieu of any fractional share of Parent Common Stock) as contemplated by this Section 1. If any Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition precedent to the issuance of any certificate representing Parent Common Stock, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit and to deliver a bond (in such sum as Parent may reasonably direct) as indemnity against any claim that may be made against the Exchange Agent, Parent or the Surviving Corporation with respect to such Company Stock Certificate.

1.7(c) No dividends or other distributions declared or made with respect to Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Company Stock Certificate with respect to the shares of Parent Common Stock that such holder has the right to receive in the Merger until such holder surrenders such Company Stock Certificate in accordance with this Section 1.7 (at which time such holder shall be entitled, subject to the effect of applicable abandoned property laws, escheat laws or similar laws, to receive all such dividends and distributions, without interest).

1.7(d) Any portion of the Exchange Fund that remains undistributed to holders of Company Stock Certificates as of the date 180 days after the date on which the Merger becomes effective shall be delivered to Parent upon demand, and any holders of Company Stock Certificates who have not theretofore surrendered their Company Stock Certificates in accordance with this Section 1.7 shall thereafter look only to Parent for satisfaction of their claims for Parent Common Stock, cash in lieu of fractional shares of Parent Common Stock and any dividends or distributions with respect to Parent Common Stock.

1.7(e) Each of the Exchange Agent, Parent 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 Company Common Stock such amounts as may be required to be deducted or withheld therefrom under the Code or any provision of state, local or foreign tax law or under any other applicable Legal Requirement. To the extent such amounts are so deducted or withheld and paid over to the proper Governmental Body, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

1.7(f) Neither Parent nor the Surviving Corporation shall be liable to any holder or former holder of Company Common Stock or to any other Person with respect to any shares of Parent Common Stock (or dividends or distributions with respect thereto), or for any cash amounts, properly delivered to any public official pursuant to any applicable abandoned property law, escheat law or similar Legal Requirement.

1.8 Treatment of Options and Other Stock-Based Awards.

1.8(a) At the Effective Time, each option granted (or previously assumed) by the Company to purchase shares of Company Common Stock (each a “Company Option”), which is outstanding and unexercised immediately prior to the Effective Time (each an “Outstanding Company Option”) shall cease to represent a right to acquire shares of Company Common Stock and shall be assumed by Parent and converted automatically, into an option to purchase shares of Parent Common Stock (a “Converted Option”) in an amount and at an exercise price determined as provided below (and each Converted Option otherwise shall remain subject to the terms of the Company’s Amended and Restated 2003 Stock Incentive Plan, 2003 Director Stock Option Plan or 1998 Special Equity Incentive Plan, or other governing share-based plan document, including plan documents governing options that have previously been assumed by the Company as a result of corporate acquisition transactions by the Company, as applicable (collectively, and in each case as the same may be amended from time to time, the “Company Stock Plans”) and the applicable agreement, notice or letter evidencing the grant of the Company Option thereunder).

(i) the number of shares of Parent Common Stock to be subject to the Converted Option shall be equal to the product of (x) the number of shares of Company Common Stock subject to the Outstanding Company Option and (y) the Exchange Ratio, provided that any fractional shares of Parent Common Stock resulting from such multiplication shall be rounded down to the nearest whole share; and

(ii) the exercise price per share of Parent Common Stock under the Converted Option shall be equal to the exercise price per share of Company Common Stock under the Outstanding Company Option divided by the Exchange Ratio, provided that such exercise price shall be rounded up to the nearest cent.

In the case of any Outstanding Company Option which is, immediately prior to the Effective Time, an “incentive stock option” (as defined in Section 422 of the Code), the exercise price, the number of shares purchasable pursuant to the corresponding Converted Option and the terms and conditions of exercise of such Converted Option shall be determined in order to comply with Section 424(a) of the Code and to avoid a “modification” of any such option under Section 424(h) of the Code. In all events, Outstanding Company Options shall be converted into Converted Options in such a manner as to be compliant with Section 409A of the Code (or an available exemption therefrom) and any guidance issued thereupon by the U.S. Department of Treasury. Except as otherwise provided in this section, the duration and other terms of each Converted Option (including vesting provisions) shall be the same as those of the applicable Outstanding Company Option, except that all references to the Company shall be deemed to be references to Parent. Prior to the Effective Time, the Company and Parent shall take all action necessary to be taken in order to effect the foregoing provisions of this section.

1.8(b) At the Effective Time, each restricted stock unit award granted (or previously assumed) by the Company representing a right to receive upon a future date or dates shares of Company Common Stock (each a “Company RSU Award”) which is outstanding and which has not been settled by the issuance of shares of Company Common Stock immediately prior to the Effective Time (each an “Outstanding Company RSU Award”) shall cease to represent a right to receive upon settlement thereof shares of Company Common Stock and shall be assumed by Parent and converted automatically into a right to receive upon settlement thereof shares of Parent Common Stock (a “Converted RSU Award”) in an amount determined as provided below (and each Converted RSU Award otherwise shall remain subject to the terms of the applicable Company Stock Plan, and the applicable agreement, notice or letter evidencing the grant of the Company RSU Award thereunder. The number of shares of Parent Common Stock to be subject to the Converted RSU Award shall be equal to the product

of (x) the number of shares of Company Common Stock subject to the Outstanding Company RSU Award and (y) the Exchange Ratio, provided that any fractional shares of Parent Common Stock resulting from such multiplication shall be rounded down to the nearest whole share. Prior to the Effective Time, the Company shall take all action necessary to be taken by the Company in order to effect the foregoing provisions of this Section.

1.8(c) Except as provided herein or as otherwise agreed to by the parties, the Company shall ensure that following the Effective Time no holder of a Company Option or a Company RSU Award nor any holder of any other equity-based right shall have any right to acquire equity securities of the Company or the Surviving Corporation.

1.8(d) As soon as reasonably practicable after the Effective Time, Parent shall deliver to each holder of a Converted Option or a Company RSU Award an appropriate notice evidencing the foregoing assumption of the option by Parent. Parent shall comply with the terms of the Company Stock Plans, as applicable, and the agreements, notices or letters, subject to the adjustments pursuant to this Section. Each holder of a Converted Option or a Company RSU Award shall be credited with such holder’s service with Company or its Subsidiaries for purposes of determining such holder’s vesting under such Converted Option or Company RSU Award.

1.8(e) Parent shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery upon the exercise of the Converted Options and settlement of the Converted RSU Awards, including the authorization for listing of such shares on The NASDAQ Stock Market. As soon as practicable after the Effective Time (but in any event, no later than ten (10) business days thereafter), Parent shall file a registration statement on Form S-8 (or any successor or other appropriate form) with respect to the shares of Parent Common Stock subject to the Converted Options and Converted RSU Awards and shall use its best efforts to maintain the effectiveness of such registration statement or registration statements for so long as the Converted Options and Converted RSU Awards remain outstanding.

1.8(f) Employees of Company and its Subsidiaries as of the Effective Time shall be permitted to participate in Parent’s employee stock purchase plan commencing on the first enrollment date of such plan following the Effective Time, subject to the eligibility provisions of such plan (with employees receiving credit, for purposes of such eligibility provisions, for service with Company or Parent or any of their respective Subsidiaries).

1.8(g) If any shares of Company Common Stock outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option, risk of forfeiture or other condition under any applicable restricted stock purchase or grant agreement or other agreement with the Company or under which the Company has any rights, then the shares of Parent Common Stock issued in exchange for such shares of Company Common Stock will also be unvested and subject to the same repurchase option, risk of forfeiture or other condition, and the certificates representing such shares of Parent Common Stock may accordingly be marked with appropriate legends. The Company shall take all action that may be necessary to ensure that, from and after the Effective Time, Parent is entitled to exercise any such repurchase option or other right set forth in any such restricted stock purchase or grant agreement or other agreement.

1.8(h) The Company Stock Plans previously approved by the Company’s stockholders will not terminate by virtue of the Merger if Parent elects to assume the available share reserves under such plans (following adjustment by the Exchange Ratio) for use under Parent’s equity plans to grant awards following the Merger to former Company employees or others who were not Parent employees prior to the Merger.

1.9 Treatment of Warrants.

1.9(a) At the Effective Time, subject to any necessary Consent of holders of warrants, each warrant issued by the Company to purchase shares of Company Common Stock (each a “Company Warrant”), which is outstanding and unexercised immediately prior to the Effective Time shall cease to represent a right to acquire shares of Company Common Stock and shall be assumed by Parent and converted automatically into a warrant to purchase shares of Parent Common Stock (a “Converted Warrant”) in an amount and at an exercise price determined as provided below (and each Converted Warrant otherwise shall remain subject to the terms of the applicable warrant agreement, notice or letter evidencing the issuance of the Company Warrant pursuant thereto).

(i) The number of shares of Parent Common Stock to be subject to a Converted Warrant shall be equal to the product of (x) the number of shares of Company Common Stock subject to the outstanding Company Warrant and (y) the Exchange Ratio, provided that any fractional shares of Parent Common Stock resulting from such multiplication shall be rounded down to the nearest whole share; and

(ii) the exercise price per share of Parent Common Stock under a Converted Warrant shall be equal to the exercise price per share of Company Common Stock under the outstanding Company Warrant divided by the Exchange Ratio, provided that such exercise price shall be rounded up to the nearest cent.

1.9(b) As soon as reasonably practicable after the Effective Time, Parent shall deliver to each holder of a Converted Warrant an appropriate notice evidencing the foregoing assumption of the Company Warrant by Parent.

1.9(c) Parent shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery upon the exercise of the Converted Warrants, including the authorization for listing of such shares on the applicable national securities exchange.

1.10 Tax Consequences. For federal income tax purposes, the Merger is intended to constitute a reorganization within the meaning of Section 368(a) of the Code. The parties to this Agreement hereby adopt this Agreement as a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations.

1.11 Further Action. If, at any time after the Effective Time, any further action is determined by Parent to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Merger Sub and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Merger Sub, in the name of the Company and otherwise) to take such action.

SECTION 2: REPRESENTATIONS AND WARRANTIES OF THE COMPANY. Except as set forth in the Company Disclosure Schedule, the Company represents and warrants to Parent and Merger Sub as follows:

2.1 Organization and Good Standing.

2.1(a) The Acquired Corporations are corporations or other Entities duly organized, validly existing, and in good standing (where such concept is applicable) under the laws

of their respective jurisdictions of incorporation or organization, with full corporate power or other entity authority to conduct their respective businesses as now being conducted, to own or use the respective properties and assets that they purport to own or use, and to perform all their respective obligations under Acquired Corporation Contracts. Each of the Acquired Corporations is duly qualified to do business as a foreign corporation or other entity and is in good standing (where such concept is applicable) under the laws of each state or other jurisdiction in which either the ownership or use of the properties owned or used by it, or the nature of the activities conducted by it, requires such qualification, except where the failure to be so qualified would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect on the Acquired Corporations.

2.1(b) Part 2.1(b) of the Company Disclosure Schedule lists, as of the date hereof, all Acquired Corporations and indicates as to each the type of entity, its jurisdiction of organization and, except in the case of the Company, its stockholders or other equity holders. The Company has made available to Parent copies of, the certificate or articles of incorporation, by-laws and other organizational documents (collectively, the “Organizational Documents”) of each of the Acquired Corporations, as currently in effect. For the purposes of this Agreement, the phrase “made available” when used in connection with the Company shall constitute the production by the Company of such document(s) in an electronic dataroom for purposes of review by Parent and its legal counsel and advisors in connection with the negotiation of this Agreement.

2.1(c) The Company has made available to Parent copies of, the charters of each committee of the Company’s board of directors and any code of conduct or similar policy adopted by the Company.

2.2 Authority; No Conflict.

2.2(a) The Company has all necessary corporate power and authority to execute and deliver this Agreement and the other agreements referred to in this Agreement to which it is a party, to perform its obligations hereunder and thereunder and to consummate the Merger and the other transactions contemplated hereby and thereby (collectively, and including where applicable the transactions contemplated by the Voting Undertakings, the “Contemplated Transactions”). The execution and delivery of this Agreement by the Company and the consummation by the Company of the Contemplated Transactions have been duly and validly authorized by all necessary corporate action and no other corporate proceedings on the part of the Company are necessary to authorize this Agreement or to consummate the Contemplated Transactions (other than, with respect to the Merger, the Required Stockholder Vote and the filing of appropriate merger documents as required by the DGCL). The Board of Directors of the Company (the “Company Board”), with one director being recused, has unanimously approved this Agreement, declared it to be advisable and resolved to recommend to the stockholders of the Company that they vote in favor of the adoption of this Agreement in accordance with the DGCL. This Agreement has been duly and validly executed and delivered by the Company and, assuming the due execution and delivery of the Agreement by Parent and Merger Sub, constitutes the legal, valid and binding obligations of the Company, enforceable against the Company in accordance with its terms subject to the effect of (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to rights of creditors generally and (ii) rules of law and equity governing specific performance, injunctive relief and other equitable remedies.

2.2(b) Neither the execution and delivery of this Agreement nor the consummation of any of the Contemplated Transactions do or will, directly or indirectly (with or without notice or lapse of time or both), (i) contravene, conflict with, or result in a violation of any provision of the Organizational Documents of any of the Acquired Corporations; (ii) contravene, conflict with, or result in a violation of any Legal Requirements or any order to which any of the Acquired Corporations,

or any of the assets owned or used by any of the Acquired Corporations, is or may be subject; or (iii) contravene, conflict with, or result in a violation or breach of any provision of, or give any Person the right to declare a default or exercise any remedy under, or to accelerate the maturity or performance of, or to cancel, terminate, or modify, any Material Contract, except, in the case of clauses (ii) and (iii), for any such conflicts, violations, breaches, defaults or other occurrences that would not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect on the Acquired Corporations.

SECTION 5: ADDITIONAL AGREEMENTS.

5.1 No Solicitation.

5.1(a) No Solicitation or Negotiation. From the date of this Agreement until the Effective Time, except as set forth in this Section 5.1, none of the Acquired Corporations shall, nor shall any of them authorize or knowingly permit any of their directors, officers, employees, investment bankers, attorneys, accountants or other advisors or representatives (such directors, officers, employees, investment bankers, attorneys, accountants, other advisors and representatives, collectively, “Representatives”) to, directly or indirectly:

(i) solicit, initiate, or knowingly or intentionally encourage or facilitate, any inquiries, offers or proposals that constitutes, or would reasonably be expected to lead to, any Acquisition Proposal, including, without limitation, amending or granting any waiver or release under any standstill or similar agreement with respect to any Company Common Stock; or

(ii) enter into, continue or otherwise participate in any discussions or negotiations regarding, furnish to any Person any non-public information with respect to, assist or participate in any effort or attempt by any Person with respect to, or otherwise knowingly or intentionally cooperate in any way with, any Acquisition Proposal (provided, however, that providing notice of the restrictions set forth in this Section 5.1 to a third party in response to any such inquiry, request or Acquisition Proposal shall not, in and of itself, be deemed a breach of this Section).

Notwithstanding the foregoing, prior to the time that the Required Stockholder Vote has been obtained (the “Specified Time”), the Company may, to the extent the failure to take such action would be inconsistent with the fiduciary obligations of the Company Board, as determined in good faith by the Company Board after consultation with outside counsel, in response to a bona fide written Acquisition Proposal made or received after the date of this Agreement that the Company Board determines in good faith after consultation with outside counsel and its financial advisor is reasonably likely to lead to a Superior Proposal, in each case that did not result from a breach by the Company of this Section, and subject to compliance with Section 5.1(c), (x) furnish non-public information with respect to any of the Acquired Corporations to the Person making such Acquisition Proposal and its Representatives, and (y) participate in discussions or negotiations (including the negotiation of documentation) with such Person and

its Representatives regarding such Acquisition Proposal, if, in the case of either clause (x) or (y), prior to taking such action the Company enters into a confidentiality agreement not less restrictive of the other party than the Confidentiality Agreement.

5.1(b) No Change in Recommendation or Alternative Acquisition Agreement. Neither the Company Board nor any committee thereof shall:

(i) except as set forth in this Section, withdraw, qualify or modify, or publicly propose to withdraw, qualify or modify, in a manner adverse to Parent or the Merger Sub, the approval or recommendation by the Company Board or any such committee of the adoption of this Agreement (an “Adverse Recommendation Change”);

(ii) adopt, approve or recommend, or publicly propose to adopt, approve or recommend, any Acquisition Proposal; or

(iii) authorize, cause or permit any of the Acquired Corporations to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or similar agreement (an “Alternative Acquisition Agreement”) constituting or relating to any Acquisition Proposal (other than a confidentiality agreement referred to in Section 5.1(a) entered into in the circumstances referred to in Section 5.1(a)).

Notwithstanding the foregoing, at any time prior to the Specified Time and subject to Section 5.1(c), the Company Board may, in response to an Acquisition Proposal that the Company Board determines in good faith (after consultation with its outside counsel and its financial advisor) constitutes a Superior Proposal and that was made after the date hereof and that did not result from a breach of this Section 5.1, make an Adverse Recommendation Change if the Company Board has concluded in good faith, after consultation with its outside counsel, that, in light of such Superior Proposal, the failure of the Company Board to effect an Adverse Recommendation Change would be inconsistent with its fiduciary duties under applicable Legal Requirements; provided, however, that the Company shall not be entitled to exercise its right to make an Adverse Recommendation Change pursuant to this sentence unless the Company has: (A) provided to Parent three business days’ prior written notice (such notice, a “Notice of Superior Proposal”), which notice shall not be deemed to be a Adverse Recommendation Change, advising Parent that the Company Board intends to take such action and specifying the reasons therefor, including the then current material terms and conditions of any Superior Proposal that is the basis of the proposed action by the Company Board and the identity of the Person making the proposal (it being understood and agreed that any amendment to the financial terms or any material amendment to any other material term of any such Superior Proposal shall require a new Notice of Superior Proposal and a new two business day period), (B) during the applicable notice period, if requested by Parent, engaged in good faith negotiations with Parent to amend this Agreement in such a manner that any Acquisition Proposal which was determined to constitute a Superior Proposal no longer is a Superior Proposal and (C) at the end of the applicable notice period, such Acquisition Proposal has not been withdrawn and continues to constitute a Superior Proposal (taking into account any changes to the terms of this Agreement proposed by Parent following a Notice of Superior Proposal, as a result of the negotiations required by clause (A) or otherwise).

In addition, and notwithstanding any provision to the contrary in this Section 5.1, at any time prior to the Specified Time the Company Board may, in response to a material development or change in circumstances occurring or arising after the date hereof that was neither known to the Company Board nor reasonably foreseeable as of or prior to the date hereof (and not relating to any Acquisition Proposal) (such material development or change in circumstances, an “Intervening Event”), make an Adverse Recommendation Change if the Company Board has concluded in good faith, after consultation with its

outside counsel, that, in light of such Intervening Event, the failure of the Company Board to effect such an Adverse Recommendation Change would be inconsistent with its fiduciary duties under applicable Legal Requirements; provided that, the Company Board shall not be entitled to exercise its right to make an Adverse Recommendation Change pursuant to this sentence unless the Company has (x) provided to Parent at least three business days’ prior written notice (unless the Intervening Event arises fewer than three business days prior to the Stockholders’ Meeting) advising Parent that the Company Board intends to take such action and specifying the reasons therefor in reasonable detail and (y) during such three business day period, if requested by Parent, engaged in good faith negotiations with Parent to amend this Agreement in such a manner that obviates the need for an Adverse Recommendation Change as a result of the Intervening Event.

Nothing in this Section 5.1 shall be deemed prior to the termination of this Agreement to (A) permit the Company to take any action described in clauses (ii) or (iii) of the first sentence of this Section 5.1(b), or (B) affect any obligation of the Company under this Agreement or limit the Company’s obligation to call, give notice of, convene and hold the Stockholders’ Meeting, regardless of whether the Company Board has withdrawn or modified its recommendation of this Agreement and the Merger.

The Company shall not provide any information to or participate in discussions or negotiations with the Person making any Acquisition Proposal until after the Company has first notified Parent of such Acquisition Proposal as required by the preceding sentence. The Company shall keep Parent reasonably informed in all material respects of the status of any such Acquisition Proposal and shall (i) promptly (within 24 hours of gaining Knowledge) notify Parent if it has begun to furnish information to, or to participate in discussions or negotiations with, a Person making any such Acquisition Proposal or inquiry and shall promptly (within 24 hours of gaining Knowledge) notify Parent of any material change in the terms of any such Acquisition Proposal or inquiry, (ii) provide to Parent as soon as practicable after receipt or delivery thereof any correspondence or proposed transaction documents received from or on behalf of any third party relating to the terms of any Acquisition Proposal and (iii) if Parent shall make a counterproposal (including, without limitation, following delivery of a written notice to Parent pursuant to Section 5.1(b)), consider and cause its financial and legal advisors to consider in good faith the terms of such counterproposal.

Any investigation conducted pursuant to the access contemplated by this Section 5.4 shall be conducted in a manner that does not unreasonably interfere with the conduct of the business of the parties or their respective Subsidiaries, as the case may be, or create a risk of damage or destruction to any property or assets of the parties or their respective Subsidiaries. During such period, the Company and Parent shall furnish or make available promptly to each other (except as otherwise available on EDGAR) (a) a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of federal or state securities laws and (b) all other information concerning its business, properties, assets and personnel as the other may reasonably request.

[Catalyst Semiconductor, Inc. Letterhead]

[DATE]

O’Melveny & Myers LLP

275 Battery Street, Suite 2600

San Francisco, California 94111

DLA Piper US LLP

2000 University Avenue

East Palo Alto, CA 94301

Ladies and Gentlemen:

We refer to the Agreement and Plan of Merger and Reorganization (the “Merger Agreement”)*, dated as of July 16, 2008, by and among ON Semiconductor, Inc., a Delaware corporation (“Parent”), Centaur Acquisition Corporation, a Delaware corporation and direct wholly owned subsidiary of Parent (“Merger Sub”), and Catalyst Semiconductor, Inc., a Delaware corporation (“Company”), which provides for the merger (the “Merger”) of Merger Sub with and into Company, with Company as the surviving corporation, in accordance with the DGCL and on the terms and conditions set forth therein. Each of DLA Piper, counsel to Parent and Merger Sub, and O’Melveny & Myers LLP, counsel to Company, has been requested pursuant to Section 6.1(f), of the Merger Agreement to render its opinion regarding certain United States federal income tax consequences of the Merger.

A.	Statements and Representations.

In connection with such opinions, and acknowledging that each of you will rely, with Company’s consent, upon the statements and representations made in this letter in rendering such opinion, Company hereby certifies and represents to each of you that (i) the facts, representations and covenants that relate to the Merger and related transactions, as described in the Form S-4 Registration Statement filed in connection with the Merger and the Proxy Statement/Prospectus contained therein, each as amended or supplemented through the date hereof, are, to the extent relating to Company (and to the extent otherwise without reason to believe to the contrary), true, correct, and complete in all material respects and will be true, correct, and complete in all material respects at the Effective Time and (ii) the statements and

*	Except as otherwise provided, capitalized terms used but not defined herein have the meaning ascribed to them in the Merger Agreement. Except as otherwise indicated, all “Section” references contained herein refer to sections of the Internal Revenue Code of 1986, as amended.

representations made herein are true, correct and complete in all respects as of the date hereof and will be true, correct and complete in all respects at the Effective Time (as if made as of the Effective Time) and thereafter (where relevant):

1. The Merger will be effected for bona fide non-tax business reasons and will be carried out strictly in accordance with the Merger Agreement, applicable state corporation laws and as described in the Proxy Statement/Prospectus. None of the material terms and conditions contained in the Merger Agreement have been or will be waived or modified.

2. The fair market value, immediately after the Effective Time, of the shares of Parent Common Stock (together with any cash paid in lieu of fractional shares) to be received in the Merger by each holder of Company Common Stock will be approximately equal to the fair market value, immediately before the Effective Time, of the shares of Company Common Stock to be surrendered in exchange therefor, and the aggregate fair market value of the Parent Common Stock (together with any cash paid in lieu of fractional shares) received in the Merger by holders of Company Common Stock (“Company Stockholders”) will be approximately equal to the fair market value of Company Common Stock surrendered by such Company Stockholders in exchange therefor. In connection with the Merger, no Company Stockholder will receive in exchange for Company Common Stock, directly or indirectly, any consideration other than the Parent Common Stock (together with any cash paid in lieu of fractional shares) received in the Merger. No shares of Merger Sub have been or will be used as consideration or issued to Company Stockholders in the Merger.

3. Immediately following the Merger and at the Effective Time, Company will hold assets representing at least ninety percent (90%) of the fair market value of Company’s net assets and at least seventy percent (70%) of the fair market value of Company’s gross assets held by Company immediately prior to the Merger. For purposes of this representation, the following assets will be included as assets of Company held by Company immediately prior but not subsequent to the Merger: (i) assets used by Company to pay Company Stockholders receiving cash in lieu of fractional shares of Parent Common Stock; (ii) assets used to pay expenses or liabilities incurred in connection with the Merger; (iii) assets paid by Company to Company Stockholders who receive cash or other property; and (iv) assets used by Company to make distributions, redemptions, or other payments in respect of Company Common Stock or rights to acquire such stock (including payments treated as such for tax purposes) that are made as part of an overall plan of which the Merger is a part.

4. Neither Company nor any person related to Company within the meaning of Treasury Regulation Section 1.368-1(e)(3), (e)(4) and (e)(5) (a “Company Related Person”) has, directly or indirectly, purchased, redeemed or otherwise acquired, or made any distributions with respect to, any Company capital stock prior to and in contemplation of the Merger, or otherwise as part of a plan of which the Merger is a part.

5. To the best knowledge of the management of Company, there is no plan or intention on the part of Company Stockholders to sell, exchange or otherwise transfer ownership of any Parent Common Stock received in the Merger to Parent or any person related to Parent within the meaning of Treasury Regulation Section 1.368-1(e)(3), (e)(4) and (e)(5) (a “Parent Related Person”), directly or indirectly, other than through open-market purchases of Parent Common

Stock pursuant to a general stock repurchase program of Parent that has not been created or modified in connection with the Merger and was not a matter negotiated with Company Stockholders. To the best knowledge of the management of Company, following the Merger, no dividends or other distributions will be made to the former Company Stockholders by Parent other than regular, normal dividends or distributions made to all holders of Parent Common Stock. To the best knowledge of the management of Company, with respect to such purchases on the open market, (a) there is no understanding between Company Stockholders and Parent or any Parent Related Person that the ownership of Parent Common Stock would be transitory, (b) because of the mechanics of an open market purchase, Parent does not and will not know the identity of a seller of Parent Common Stock, nor does a former Company Stockholder who receives Parent Common Stock in the Merger and subsequently sells it know whether Parent is the purchaser of the Parent Common Stock, (c) without regard to the repurchase program, a market exists for the newly-issued Parent stock held by the former Company Stockholders, (d) during the time Parent undertakes its repurchase program, there will be sales of Parent Common Stock on the open market, which may include sales of shares of Parent Common Stock by former Company Stockholders, (e) the number of shares repurchased will not exceed the total number of shares of Parent Common Stock issued and outstanding prior to the Merger and (f) any repurchases will be made following the Merger, on the open market, through a broker for the prevailing market price.

6. Company conducts a “historic business” within the meaning of Treasury Regulation Section 1.368-1(d). No assets of Company have been or will be sold, transferred or otherwise disposed of which would prevent Parent or any member of Parent’s “qualified group” from continuing the “historic business” of Company or from using a “significant portion” of Company’s “historic business assets” in a business following the Merger, as such terms are used in Treasury Regulation Section 1.368-1(d). For purposes of this test, Parent and such members (a) shall be deemed to own that portion of the assets of a partnership reflecting their interests therein (b) shall be treated as conducting the business of a partnership of which they are partners, provided that (A) they own in the aggregate at least a 33¹/3% capital and profits interest in such partnership or (B) they own in the aggregate at least a 20% capital and profits interest in such partnership and perform active and substantial managerial functions with respect thereto. A “qualified group” is one or more chains of corporations connected through stock ownership with Parent, but only if Parent owns directly stock meeting the “control” requirements of Section 368(c) in at least one other corporation, and stock meeting the “control” requirements of Section 368(c) in each of the corporations (except Parent) is owned directly (or indirectly through partnerships as described in the next sentence) by one or more of the other corporations. Solely for purposes of the definition of “qualified group,” if members of the qualified group own interests in a partnership meeting requirements equivalent to the “control” requirements of Section 368(c) (a “368(c) Controlled Partnership”), any stock owned by such 368(c) Controlled Partnership will be treated as owned by members of the qualified group. Solely for purposes of determining whether a lower-tier partnership is a 368(c) Controlled Partnership, any interest in a lower-tier partnership owned by a Section 368(c) Controlled Partnership will be treated as owned by members of the qualified group. The “control” requirements of Section 368(c) consist of direct ownership of shares of stock of a corporation possessing at least eighty percent (80%) of the total combined voting power of all classes of stock entitled to vote and at least eighty percent (80%) of the total number of shares of each other class of stock of the corporation. For purposes of determining control, a person shall not be considered to own shares of voting stock if rights to vote such shares or to restrict or otherwise control the vote of such shares are held by a third party (including a voting trust) other than an agent of such person.

7. Company has no plan or intention to issue additional shares of its stock that would result in Parent losing control of Company within the meaning of Section 368(c). At the Effective Time, Company will not have outstanding any warrants, options, convertible securities, or any other type of right pursuant to which any person could acquire stock in Company that, if exercised or converted, would affect Parent’s acquisition or retention of control of Company, within the meaning of Section 368(c). No liabilities of any Company Stockholder will be assumed by Parent or Merger Sub, nor will any shares of Company Common Stock be acquired subject to any liabilities.

8. In the Merger, Company Common Stock representing control of Company (within the meaning of Section 368(c)) will be exchanged solely for voting stock of Parent (within the meaning of Sections 368(a)(1)(B) and (2)(E)). For purposes of this paragraph 8, Company Common Stock exchanged for cash or other property originating with Parent is treated as constituting outstanding Company Common Stock on the date of the Merger. To the best knowledge of the management of Company, as of the Effective Time, neither Parent nor any Parent Related Person will own beneficially or of record, or will have owned beneficially or of record, during the five years immediately prior to such time, any stock of Company, or other securities, options, warrants or instruments giving the holder thereof the right to acquire Company Common Stock or other securities issued by Company.

9. Except as provided in Section 7.3 of the Merger Agreement, Company and each Company Stockholder has paid and will pay only their respective expenses, if any, incurred in connection with or as part of the Merger. Company has not paid and will not pay, directly or indirectly, and has not agreed to assume and will not assume, directly or indirectly, any expense or other liability, whether fixed or contingent, incurred by any Company Stockholder in connection with or as part of the Merger or any related transaction.

10. There is no intercorporate indebtedness existing between Parent (or any of its subsidiaries), on the one hand, and Company (or any of its subsidiaries), on the other hand, that was issued, acquired or will be settled at a discount.

11. Company is not an “investment company” as defined in Sections 368(a)(2)(F)(iii) and (iv).

12. Company is not under the jurisdiction of a court in a title 11 of the United States Code or similar case within the meaning of Section 368(a)(3)(A).

13. Except for cash paid in lieu of fractional shares of Parent Common Stock, one hundred percent (100%) of Company Common Stock outstanding immediately prior to the Effective Time will be exchanged solely for Parent Common Stock. The payment of cash, if any, in lieu of fractional shares of Parent Common Stock in the Merger represents a mere mechanical rounding off solely for the purpose of avoiding the expense and inconvenience to Parent of issuing fractional shares and does not represent separately bargained-for consideration. The total cash consideration that will be paid in the Merger to Company Stockholders in lieu of issuing

fractional shares of Parent Common Stock will not exceed one percent (1%) of the total consideration that will be issued in the Merger to Company Stockholders in exchange for their Company Common Stock. The fractional share interests of each Company Stockholder will be aggregated, and no Company Stockholder, with the possible exception of Company Stockholders whose holdings are in multiple accounts or with multiple brokers, will receive cash in an amount equal to or greater than the value of one full share of Parent Common Stock.

14. No compensation received by any Company Stockholder that is an employee or otherwise renders services to Company is or will be separate consideration for, or allocable to, any of their shares of Company Common Stock. None of the shares of Parent Common Stock received by any Company Stockholder, as part of any overall plan of which the Merger is a part, is or will be separate consideration for, or allocable to, any employment, consulting or similar arrangement which may be entered into between Parent or any affiliate thereof and such stockholder for services rendered or to be rendered by such stockholder. Any compensation paid or to be paid to any Company Stockholder who will be an employee of or who will otherwise render services to Parent or any affiliate thereof after the Merger, will be in consideration of services actually rendered or to be rendered, and will be commensurate with amounts paid to third parties bargaining at arm’s-length for similar services, and has been bargained for independent of negotiations specifically regarding the consideration to be paid for Company Common Stock in the Merger.

15. The fair market value of Company’s assets equal or exceed the sum of its liabilities, plus (without duplication) the amount of liabilities, if any, to which the assets are subject.

16. The terms of the Merger Agreement and all other agreements entered into in connection therewith are the product of arm’s length negotiations. The Merger Agreement represents the entire agreement among Parent, Merger Sub and Company with respect to the Merger, and there are no other written or oral agreements regarding the Merger (or any transaction related thereto) other than those expressly referred to in the Merger Agreement and the Proxy Statement/Prospectus.

17. Company has no outstanding equity interests other than Company Common Stock. All of Company’s currently outstanding financial positions that Company has ever treated as indebtedness for federal income tax purposes (by deducting interest or otherwise) are properly classified as indebtedness rather than as equity for such purposes and have not been treated as other than indebtedness for any other purpose. The only currently outstanding financial positions of Company that Company has ever treated as equity for federal income tax purposes are shares of Company Common Stock.

18. Company Stockholders will not be entitled to any dissenters’ or similar rights in connection with the Merger.

19. The undersigned is authorized to make all of the representations set forth herein.

B.	Reliance by You in Rendering Opinion: Limitations on Your Opinion.

The undersigned recognizes and agrees that, with respect to each of you, your tax opinion will be based (i) on the statements and representations set forth herein, (ii) on the statements contained in the Merger Agreement and documents related thereto (including, but not limited to, the Form S-4 Registration Statement and Proxy Statement/Prospectus), and (iii) on the consummation of the Merger in accordance with the terms set forth in the Agreement. Each of you may, in rendering your opinion, assume that any statements and representations referred to in (i) and (ii) that are qualified by knowledge are true, correct and complete without such qualification. The undersigned also recognizes and agrees that, with respect to each of you, your tax opinion will be subject to certain limitations and qualifications, including that it may not be relied upon if any such statements or representations are not accurate in all respects.

Company undertakes to inform each of you immediately should any of the foregoing statements or representations become untrue, incorrect or incomplete in any respect at or prior to the Effective Time.

Ladies and Gentlemen:

A.	Statements and Representations.

In connection with such opinions, and acknowledging that each of you will rely, with the consent of Parent and Merger Sub, upon the statements and representations made in this letter in rendering such opinion, Parent and Merger Sub hereby certify and represent to each of you that (i) the facts, representations and covenants that relate to the Merger and related transactions, as described in the Form S-4 Registration Statement filed in connection with the Merger and the Proxy Statement/Prospectus contained therein, each as amended or supplemented through the date hereof, are, to the extent relating to Parent (and to the extent otherwise without reason to believe to the contrary), true, correct, and complete in all material respects and will be

*	Except as otherwise provided, capitalized terms used but not defined herein have the meaning ascribed to them in the Merger Agreement. Except as otherwise indicated, all “Section” references contained herein refer to sections of the Internal Revenue Code of 1986, as amended.

true, correct, and complete in all material respects at the Effective Time and (ii) the statements and representations made herein are true, correct and complete in all respects as of the date hereof and will be true, correct and complete in all respects at the Effective Time (as if made as of the Effective Time) and thereafter (where relevant).

2. The fair market value, immediately after the Effective Time, of the shares of Parent Common Stock (together with any cash paid in lieu of fractional shares) to be received in the Merger by each holder of Company Common Stock will be approximately equal to the fair market value, immediately before the Effective Time, of the shares of Company Common Stock to be surrendered in exchange therefor, and the aggregate fair market value of the Parent Common Stock (together with any cash paid in lieu of fractional shares) received in the Merger by holders of Company Common Stock (“Company Stockholders”) will be approximately equal to the fair market value of Company Common Stock surrendered by such holders in exchange therefor. In connection with the Merger, no Company Stockholders will receive in exchange for Company Common Stock, directly or indirectly, any consideration other than the Parent Common Stock (together with any cash paid in lieu of fractional shares) received in the Merger. No shares of Merger Sub have been or will be used as consideration or issued to Company Stockholders in the Merger.

3. Assuming the correctness of the representation in paragraph 3 of the representation letter executed by Company, immediately following the Merger and at the Effective Time, Company will hold (i) Company assets representing at least ninety percent (90%) of the fair market value of Company’s net assets and at least seventy percent (70%) of the fair market value of Company’s gross assets held by Company immediately prior to the Merger and (ii) Merger Sub assets representing at least ninety percent (90%) of the fair market value of Merger Sub’s net assets and at least seventy percent (70%) of the fair market value of Merger Sub’s gross assets held by Merger Sub immediately prior to the Merger. For purposes of this representation, the following assets will be included as assets of Company or Merger Sub held by Company or Merger Sub, as appropriate, immediately prior but not subsequent to the Effective Time: (i) assets used to pay Company Stockholders receiving cash in lieu of fractional shares of Parent Common Stock; (ii) assets used to pay expenses or liabilities incurred in connection with the Merger; (iii) assets paid to Company Stockholders who receive cash or other property; and (iv) assets used to make distributions, redemptions, or other payments in respect of Company Common Stock or rights to acquire such stock (including payments treated as such for tax purposes) that are made as part of an overall plan of which the Merger is a part.

4. Except with respect to open-market purchases of Parent Common Stock pursuant to a general stock repurchase program of Parent that has not been created or modified in connection with the Merger and was not a matter negotiated with Company Stockholders, neither Parent nor any person related to Parent within the meaning of Treasury Regulation Section 1.368-1(e)(3), (e)(4) and (e)(5) (a “Parent Related Person”) has any plan or intention to purchase,

redeem or otherwise acquire, directly or indirectly, any of the Parent Common Stock that will be issued pursuant to the Merger. Following the Merger, no dividends or other distributions will be made to the former Company Stockholders by Parent other than regular, normal dividends or distributions made to all holders of Parent Common Stock. With respect to such purchases on the open market, (a) there is no understanding between Company Stockholders and Parent or any Parent Related Person that the ownership of Parent Common Stock would be transitory, (b) because of the mechanics of an open market purchase, Parent does not and will not know the identity of a seller of Parent Common Stock, nor does a former Company Stockholder who receives Parent Common Stock in the Merger and subsequently sells it know whether Parent is the purchaser of the Parent Common Stock, (c) without regard to the repurchase program, a market exists for the newly-issued Parent stock held by the former Company Stockholders, (d) during the time Parent undertakes its repurchase program, there will be sales of Parent Common Stock on the open market, which may include sales of shares of Parent Common Stock by former Company Stockholders, (e) the number of shares repurchased will not exceed the total number of shares of Parent Common Stock issued and outstanding prior to the Merger and (f) any repurchases will be made following the Merger, on the open market, through a broker for the prevailing market price.

5. As of the Effective Time, neither Parent nor any Parent Related Person will own beneficially or of record, or will have owned beneficially or of record, during the five years immediately prior to such time, any stock of Company, or other securities, options, warrants or instruments giving the holder thereof the right to acquire Company Common Stock or other securities issued by Company.

6. Parent has no plan or intention: (i) to liquidate Company or to merge Company into another entity; (ii) to sell or otherwise dispose of any stock in Company held by Parent,; or (iii) to sell or otherwise dispose of, or to cause Company to sell or otherwise dispose of, any of Company’s assets or any of the assets of Merger Sub acquired in the Merger, except for dispositions in the ordinary course of business consistent with past practices (if, after any such dispositions, the representations set forth in paragraph 3 of this representation letter would continue to be accurate, assuming the accuracy of the representations set forth in paragraph 3 of the representation letter executed by the Company); provided that so long as Parent or a member of Parent’s “qualified group” (as defined below) would continue to hold the amount of assets set forth in paragraph 11 of this representation letter following the Merger (assuming the correctness of the representations set forth in paragraph 6 of the representation letter executed by Company):

(a) with respect to (ii), Company may make distributions of stock so long as such distributions do not (1) cause Company to cease to be a member of Parent’s “qualified group” (as defined below) or (2) in the aggregate, consist of all of the stock of Company that was acquired in the Merger;

(b) with respect to (iii), Company may make distributions of such assets so long as the aggregate amount of such distributions does not consist of an amount of assets of Company (disregarding any assets of Merger Sub acquired by Company in the Merger) that would result in a liquidation of Company for U.S. federal income tax purposes; and

(c) with respect to (ii) and (iii), Company may transfer all or part of such stock or assets (or a combination thereof) if such transfer does not constitute a distribution and Company does not cease to be a member of Parent’s “qualified group” (as defined below) or terminate its corporate existence in connection with the transfers.

A “qualified group” is one or more chains of corporations connected through stock ownership with Parent, but only if Parent owns directly stock meeting the “control” requirements of Section 368(c) in at least one other corporation, and stock meeting the “control” requirements of Section 368(c) in each of the corporations (except Parent) is owned directly (or indirectly through partnerships as described in the next sentence) by one or more of the other corporations. Solely for purposes of the definition of “qualified group,” if members of the qualified group own interests in a partnership meeting requirements equivalent to the “control” requirements of Section 368(c) (a “368(c) Controlled Partnership”), any stock owned by such 368(c) Controlled Partnership will be treated as owned by members of the qualified group. Solely for purposes of determining whether a lower-tier partnership is a 368(c) Controlled Partnership, any interest in a lower-tier partnership owned by a Section 368(c) Controlled Partnership will be treated as owned by members of the qualified group. The “control” requirements of Section 368(c) consist of direct ownership of shares of stock of a corporation possessing at least eighty percent (80%) of the total combined voting power of all classes of stock entitled to vote and at least eighty percent (80%) of the total number of shares of each other class of stock of the corporation. For purposes of determining control, a person shall not be considered to own shares of voting stock if rights to vote such shares or to restrict or otherwise control the vote of such shares are held by a third party (including a voting trust) other than an agent of such person.

7. Merger Sub is an entity newly formed for the purpose of participating in the Merger, and at no time prior to the Effective Time has had assets (other than nominal assets contributed upon the formation of Merger Sub, which assets will be held by the Merger Sub following the Merger, and assets that are part of the consideration to be distributed to Company Stockholders in the Merger) or business operations.

8. Merger Sub will have no liabilities assumed by Company and will not transfer to Company any assets subject to liabilities in the Merger.

9. Parent is in “control” of Merger Sub within the meaning of Section 368(c). Immediately following the Merger, Parent will be in control of Company within the meaning of Section 368(c). Parent has no plan or intention to cause Company, after the Merger, to issue additional shares of stock that, or to grant any warrants, options, convertible securities or any type of right pursuant to which any person could acquire stock of Company that, if exercised or converted, would result in Parent losing control of Company within the meaning of Section 368(c).

10. In the Merger, Company Common Stock representing control of Company (within the meaning of Section 368(c)) will be exchanged solely for voting stock of Parent (within the meaning of Sections 368(a)(1)(B) and (2)(E)). No liabilities of any Company Stockholder will be assumed by Parent or Merger Sub, nor will any shares of Company Common Stock be acquired subject to any liabilities. For purposes of this paragraph 10, Company Common Stock exchanged for cash or other property originating with Parent is treated as constituting outstanding Company Common Stock on the date of the Merger.

11. Assuming the correctness of the representation in paragraph 6 of the representation letter executed by Company, following the Merger, Parent, or a member of its “qualified group,” will continue the historic business of Company (or alternatively, if Company has more than one line of business, will continue at least one significant line of Company’s historic business) or use a significant portion (at least 33¹/3% by value) of Company’s historic business assets in a business, within the meaning of Treasury Regulation Section 1.368-1(d). For purposes of this test, Parent and such members (a) shall be deemed to own that portion of the assets of a partnership reflecting their interests therein (b) shall be treated as conducting the business of a partnership of which they are partners, provided that (A) they own in the aggregate at least a 33¹/3% capital and profits interest in such partnership or (B) they own in the aggregate at least a 20% capital and profits interest in such partnership and perform active and substantial managerial functions with respect thereto.

12. Except as provided in Section 7.3 of the Merger Agreement, Parent and Merger Sub have paid and will pay only their respective expenses, if any, incurred in connection with or as part of the Merger. Parent and Merger Sub have not paid and will not pay, directly or indirectly, and have not agreed to assume and will not assume, directly or indirectly, any expense or other liability, whether fixed or contingent, incurred by any Company Stockholders in connection with or as part of the Merger or any related transaction.

13. There is no intercorporate indebtedness existing between Parent (or any of its subsidiaries), on the one hand, and Company (or any of its subsidiaries), on the other hand, that was issued, acquired or will be settled at a discount.

14. Neither Parent nor Merger Sub is an “investment company” as defined in Sections 368(a)(2)(F)(iii) and (iv).

15. Neither Parent nor Merger Sub is under the jurisdiction of a court in a title 11 of the United States Code or similar case within the meaning of Section 368(a)(3)(A) of the Code.

16. Except for cash paid in lieu of fractional shares of Parent Common Stock, one hundred percent (100%) of Company Common Stock outstanding immediately prior to the Effective Time will be exchanged solely for Parent Common Stock. The payment of cash, if any, in lieu of fractional shares of Parent Common Stock in the Merger represents a mere mechanical rounding off solely for the purpose of avoiding the expense and inconvenience to Parent of issuing fractional shares and does not represent separately bargained-for consideration. The total cash consideration that will be paid in the Merger to Company Stockholders in lieu of issuing fractional shares of Parent Common Stock will not exceed one percent (1%) of the total consideration that will be issued in the Merger to Company Stockholders in exchange for their Company Common Stock. The fractional share interests of each Company Stockholder will be aggregated, and no Company Stockholder, with the possible exception of Company Stockholders whose holdings are in multiple accounts or with multiple brokers, will receive cash in an amount equal to or greater than the value of one full share of Parent Common Stock.

17. No compensation received by any holder of Company Common Stock that is an employee or otherwise renders services to Company is or will be separate consideration for, or allocable to, any of their shares of Company Common Stock. None of the shares of Parent Common Stock received by any holder of Company Common Stock, as part of any overall plan of which the Merger is a part, is or will be separate consideration for, or allocable to, any employment, consulting or similar arrangement which may be entered into between Parent or any affiliate thereof and such holder for services rendered or to be rendered by such holder. Any compensation paid or to be paid to any holder of Company Common Stock who will be an employee of or who will otherwise render services to Parent or any affiliate thereof after the Merger, will be in consideration of services actually rendered or to be rendered, and will be commensurate with amounts paid to third parties bargaining at arm’s-length for similar services, and has been bargained for independent of negotiations specifically regarding the consideration to be paid for Company Common Stock in the Merger.

18. The terms of the Merger Agreement and all other agreements entered into in connection therewith are the product of arm’s length negotiations. The Merger Agreement represents the entire agreement among Parent, Merger Sub and Company with respect to the Merger, and there are no other written or oral agreements regarding the Merger (or any transaction related thereto) other than those expressly referred to in the Merger Agreement and the Proxy Statement/Prospectus.

19. Parent will not take any position on any federal, state or local income or franchise tax return or take any other reporting position that is inconsistent with the treatment of the Merger as a reorganization within the meaning of Section 368(a), except to the extent otherwise required by a final “determination” (as defined in Section 1313(a)(1)).

20. Following the Merger, Parent will comply, and will cause Company to comply, with the record-keeping and information filing requirements of Treasury Regulation section 1.368-3.

21. Parent Common Stock entitles the holder thereof to vote in the election of the members of the board of directors of Parent.

22. The undersigned are authorized to make all of the representations set forth herein.
