Item 4. Description of Securities.

         As of September 20, 2001, the Corporation has issued and outstanding 173,962,725 shares of Common Stock, and 10,000 of preferred stock. TPG Advisors II, Inc. indirectly controls TPG Semiconductor Holdings, LLC, which directly owns 124,999,433 shares of Common Stock. The

2


foregoing entities are affiliated with the Texas Pacific Group (“TPG”). A TPG affiliate also owns 10,000 shares of the Corporation’s preferred stock. (See below for a summary of the preferred stock.)

Preferred Stock

         As of September 15, 2001, the Corporation has authorized 100,000 shares of preferred stock. The Corporation has issued and outstanding 10,000 shares of preferred stock to a TPG affiliate (“Preferred Stock”). No other preferred stock is outstanding. The Preferred Stock is designated as a Series A cumulative convertible preferred stock with a stated value of $10,000 per share. The Preferred Stock has a cumulative dividend, payable quarterly in cash, at the rate of 8.0% per annum (or, if greater during the relevant quarterly period, in an amount equal to the value of the dividends that would be paid on the common stock then issuable upon conversion of the Preferred Stock). In the event dividends are not declared or paid, the dividends will accumulate on a compounded basis. The Preferred Stock has a liquidation preference equal to the greater of (i) the stated value of the Preferred Stock plus all accrued and unpaid dividends thereon or (ii) the amount that would be payable to holders of the Preferred Stock if their shares had been converted into shares of the Corporation’s common stock immediately prior to the liquidation event.

         The Preferred Stock ranks prior to the common stock and any other junior securities with respect to the payment of dividends and liquidating distributions. The Corporation is prohibited from issuing any capital stock that ranks senior to the Preferred Stock or is redeemable prior to the Preferred Stock without the consent of the holders of a majority of the outstanding shares of Preferred Stock or, subject to certain exceptions, from creating contractual or other limitations on the ability of the Corporation or any of its subsidiaries to pay dividends on or to repurchase or redeem any of its equity securities. However, the right of a holder to receive dividend payments or other distributions in respect of the Preferred Stock is subject to and subordinated in right of payment to the payment in full and discharge of all amounts of principal, interest and fees then outstanding under the Corporation’s principal credit agreement, its senior subordinated notes, and certain other existing and future indebtedness of the Corporation.

         Each share of the Preferred Stock is convertible at the option of the holder any time into shares of Common Stock at a conversion price of $2.82 per share of Common Stock, subject to customary anti-dilution adjustments. Shareholder approval (or waiver by the Nasdaq thereof) will be required prior to the issuance of any shares of Common Stock upon conversion of the Preferred Stock in excess of 19.9% of the number of shares of Common Stock outstanding on September 7, 2001. At any time on or after the eighth anniversary of the issuance date of the Preferred Stock, the holders may require the Corporation to redeem their shares at a redemption price equal to the greater of (i) the stated value of the Preferred Stock plus all accrued and unpaid dividends thereon or (ii) 50% of the then current market price of the Common Stock (based upon the average closing price of the Common Stock over the preceding 30 trading days) and other assets and property, if any, into which one share of Preferred Stock is then convertible. Upon a change of control, the holders of the Preferred Stock may “put” their shares to the Corporation at 101% of the stated value plus accumulated and unpaid dividends.

         The holders of the Preferred Stock will be entitled to vote with the holders of the Common Stock as a single class. Each share of Preferred Stock will be entitled to approximately 3,135 votes, subject to certain adjustments for accumulated dividends and those made in accordance with the anti-dilution provisions. Under the Preferred Stock documents, TPG is entitled to designate two directors to serve on the Corporation’s Board of Directors for so long as TPG and its affiliates beneficially own at least 50% of the Preferred Stock. The holders of the Preferred Stock also have been granted registration rights in respect of the Common Stock underlying the Preferred Stock.

Item 5. Interests of Named Experts and Counsel.

         Not applicable.

Item 6. Indemnification of Directors and Officers.

         As of September 7, 2001 the Corporation entered into an Investment Agreement with an affiliate of TPG in connection with the affiliate’s acquisition of the Corporation’s Preferred Stock. In connection with this transaction, the Board of Directors of the Corporation formed a special committee (“Special Committee”) to assist with the TPG Preferred Stock purchase. As part of the Investment Agreement the Corporation agreed to indemnify and hold harmless each member of the Special Committee from and against any and all losses, penalties, judgments, suits, costs, claims, liabilities, damages and expenses (collectively “Losses”) incurred by each Special Committee member as a result of, or arising out of, any claim relating to breach of fiduciary duty or illegality (other than claims based upon fraud, embezzlement or any criminal violation of law), in each case, related to the TPG Preferred Stock purchase; provided, however, that such indemnification shall only be available to the extent that both (i) indemnification for such Losses is not available from the Corporation under applicable law or as a result of the Corporation’s insolvency, and (ii) the Corporation’s insurers refuse to pay on the Corporation’s directors’ and officers’ liability insurance policies with respect to such Losses.

The purpose of the SCG Holding Corporation 2000 Stock Incentive Plan (the "Plan") is to promote the success and enhance the value of SCG Holding Corporation (the "Company") by linking the personal interests of its members of the Board, employees, officers, and executives of, and consultants and advisors to, the Company to those of Company stockholders and by providing such individuals with an incentive for outstanding performance in order to generate superior returns to shareholders of the Company. The Plan is further intended to provide flexibility to the Company in its ability to motivate, attract, and retain the services of members of the Board, employees, officers, and executives of, and consultants and advisors to, the Company upon whose judgment, interest, and special effort the successful conduct of the Company's operation is largely dependent. ARTICLE 2 EFFECTIVE DATE 2.1 EFFECTIVE DATE. The Plan is effective as of the date the Plan is approved by the Board (the "Effective Date"). Within 12 months of the Effective Date, the Plan must be approved by the Company's shareholders. The Plan will be deemed to be approved by the shareholders if it receives the affirmative vote of the holders of a majority of the shares of stock of the Company present or represented and entitled to vote at a meeting duly held in accordance with the applicable provisions of the Company's Bylaws or by written consent of a majority of the Company's shareholders in lieu of a meeting. Any awards granted under the Plan prior to shareholder approval are effective when made (unless the Committee specifies otherwise at the time of grant), but no Award may be exercised or settled and no restrictions relating to any Award may lapse before the Plan is approved by the shareholders as provided above. If the shareholders fail to approve the Plan, any Award previously made shall be automatically canceled without any further act. ARTICLE 3 DEFINITIONS AND CONSTRUCTION 3.1 DEFINITIONS. When a word or phrase appears in this Plan with the initial letter capitalized, and the word or phrase does not commence a sentence, the word or phrase shall generally be given the meaning ascribed to it in this Section or in Sections 1.1 or 2.1 unless a clearly different meaning is required by the context. The following words and phrases shall have the following meanings: 1

If, subsequent to a Participant's termination of employment or services, it is discovered that such Participant's employment or services could have been terminated for Cause, the Participant's employment or services shall, at the election of the Board, in its sole discretion, be deemed to have been terminated for Cause retroactively to the date the events giving rise to Cause occurred. (e) "Change of Control" shall mean the occurrence of any of the following events: (i) any sale, lease, exchange, or other transfer (in one transaction or a series of related transactions) of all or substantially all of the assets of the Company or the Operating Subsidiary to any Person or group of related persons for purposes of Section 13(d) of the Exchange Act (a "Group"), together with any affiliates thereof other than TPG Semiconductor Holdings LLC, TPG Partners II, L.P., or any of their affiliates (hereafter collectively referred to as "TPG"); (ii) the approval by the holders of Stock and the consummation of any plan or proposal for the liquidation or dissolution of the Company; (iii) (A) any Person or Group (other than TPG) shall become the beneficial owner, directly or indirectly, of shares representing more than 25% of the aggregate voting power of the issued and outstanding stock entitled to vote in the election of directors (the "Voting Stock") of the Company and such Person or Group has the power and authority to vote such shares and (B) TPG beneficially owns (within the meaning of Section 13(d) of the Exchange Act), directly or indirectly, in the aggregate a lesser percentage of the Voting Stock of the Company than such other Person or Group; (iv) the actual replacement of a majority of the Board over a two-year period from the individual directors who constituted the Board at the beginning of such period, and such replacement shall not have been approved by a vote of at least a majority of the Board then still in office who either were members of such Board at the beginning of such period or whose election as a member of such Board was previously so approved or who were nominated by, or designees of, TPG; (v) any Person or 2

3 Group other than TPG shall have acquired shares of Voting Stock of the Company such that such Person or Group has the power and authority to elect a majority of the members of the Board of Directors of the Company; or (vi) the consummation of a merger or consolidation of the Company with another entity in which holders of the Stock immediately prior to the consummation of the transaction hold, directly or indirectly, immediately following the consummation of the transaction, 50% or less of the common equity interest in the surviving corporation in such transaction.

(l) "Incentive Stock Option" means an Option that is intended to meet the requirements of Section 422 of the Code or any successor provision thereto.

The Performance Criteria that will be used to establish Performance Goals are limited to the following: pre- or after-tax net earnings, sales growth, operating earnings, operating cash flow, return on net assets, return on stockholders' equity, return on assets, return on capital, Stock price growth, stockholder returns, gross or net profit margin, earnings per share, price per share of Stock, and market share, any of which may be measured either in absolute terms or as compared to any incremental increase or as compared to results of a peer group.

(t) "Performance Goals" means, for a Performance Period, the goals established in writing by the Committee for the Performance Period based upon the Performance Criteria. Depending on the Performance Criteria used to establish such Performance Goals, the Performance Goals may be expressed in terms of overall Company performance or the performance of a division, business unit, or an individual. The Committee, in its discretion, may, within the time prescribed by Section 162(m) of the Code, adjust or modify the calculation of Performance Goals for such Performance Period in order to prevent the dilution or enlargement of the rights of Participants (i) in the event of, or in anticipation of, any unusual or extraordinary corporate item, transaction, event, or development, or (ii) in recognition of, or in anticipation of, any other unusual or nonrecurring events affecting the Company, or the financial statements of the Company, or in response to, or in anticipation of, changes in applicable laws, regulations, accounting principles, or business conditions. (u) "Performance Period" means the one or more periods of time, which may be of varying and overlapping durations, as the Committee may select, over which the attainment of one or more Performance Goals will be measured for the purpose of determining a Participant's right to, and the payment of, a Performance-Based Award. (v) "Performance Share" means a right granted to a Participant under Article 9, to receive cash, Stock, or other Awards, the payment of which is contingent upon achieving certain performance goals established by the Committee. 4

5 (w) "Plan" means the SCG Holding Corporation 2000 Stock Incentive Plan, as amended. (x) "Restricted Stock Award" means Stock granted to a Participant under Article 10 that is subject to certain restrictions and to risk of forfeiture. (y) "Stock" means the common stock of the Company and such other securities of the Company that may be substituted for Stock pursuant to Article 14. (z) "Stock Appreciation Right" or "SAR" means a right granted to a Participant under Article 8 to receive a payment equal to the difference between the Fair Market Value of a share of Stock as of the date of exercise of the SAR over the grant price of the SAR, all as determined pursuant to Article 8. (aa) "Subsidiary" means any corporation or other entity of which a majority of the outstanding voting stock or voting power is beneficially owned directly or indirectly by the Company.

The Plan shall be administered by the Board or a Committee appointed by, and which serves at the discretion of, the Board. If the Board appoints a Committee, the Committee shall consist of at least two individuals, each of whom qualifies as (i) a Non-Employee Director, and (ii) an "outside director" under Code Section 162(m) and the regulations issued thereunder. Reference to the Committee shall refer to the Board if the Board does not appoint a Committee. 4.2 ACTION BY THE COMMITTEE. A majority of the Committee shall constitute a quorum. The acts of a majority of the members present at any meeting at which a quorum is present, and acts approved in writing by a majority of the Committee in lieu of a meeting, shall be deemed the acts of the Committee. Each member of the Committee is entitled to, in good faith, rely or act upon any report or other information furnished to that member by any officer or other employee of the Company or any Subsidiary, the Company's independent certified public accountants, or any executive compensation consultant or other professional retained by the Company to assist in the administration of the Plan. 4.3 AUTHORITY OF COMMITTEE.

In determining these increases of shares reserved for issuance under the Plan, relevant calculations shall be made on a non-diluted basis, i.e., excluding all shares previously reserved for issuance under the Plan and any 6

7 other equity incentive plan of the Company. Notwithstanding the foregoing, the total number of shares available for grant under the Plan as Incentive Stock Options shall be 10,000,000. 5.2 LAPSED AWARDS. To the extent that an Award terminates, expires, or lapses for any reason, any shares of Stock subject to the Award will again be available for the grant of an Award under the Plan. 5.3 STOCK DISTRIBUTED.

Subject to the provisions of Article 16 of the Plan, in order to assure the viability of Awards granted to Participants employed in foreign countries, the Committee may provide for such special terms as it may consider necessary or appropriate to accommodate differences in local law, tax policy, or custom. Moreover, the Committee may approve such supplements to, or amendments, restatements, or alternative versions of the Plan as it may consider necessary or appropriate for such purposes without thereby affecting the terms of the Plan as in effect for any other purpose; provided, however, that no such supplements, amendments, restatements, or alternative versions shall increase the share limitations contained in Section 5.1 of the Plan. 6.2 ACTUAL PARTICIPATION. Subject to the provisions of the Plan, the Committee may, from time to time, select from among all eligible individuals, those to whom Awards shall be granted and shall determine the nature and amount of each Award. No individual shall have any right to be granted an Award under this Plan. ARTICLE 7 STOCK OPTIONS 7.1 GENERAL. The Committee is authorized to grant Options to Participants on the following terms and conditions: (a) EXERCISE PRICE. The exercise price per share of Stock under an Option shall be determined by the Committee and set forth in the Award Agreement. It is the 7

8 intention under the Plan that the exercise price for any Option shall not be less than the Fair Market Value as of the date of grant; provided, however that the Committee may, in its discretion, grant Options (other than Options that are intended to be Incentive Stock Options or Options that are intended to qualify as performance-based compensation under Code Section 162(m)) with an exercise price of less than Fair Market Value on the date of grant. (b) TIME AND CONDITIONS OF EXERCISE. The Committee shall determine the time or times at which an Option may be exercised in whole or in part. The Committee shall also determine the performance or other conditions, if any, that must be satisfied before all or part of an Option may be exercised. Unless otherwise provided in an Award Agreement, an Option will lapse immediately if a Participant's employment or services are terminated for Cause. (c) PAYMENT. The Committee shall determine the methods by which the exercise price of an Option may be paid, the form of payment, including, without limitation, cash, promissory note, shares of Stock (through actual tender or by attestation), or other property (including broker-assisted "cashless exercise" arrangements), and the methods by which shares of Stock shall be delivered or deemed to be delivered to Participants. (d) EVIDENCE OF GRANT. All Options shall be evidenced by a written Award Agreement between the Company and the Participant. The Award Agreement shall include such additional provisions as may be specified by the Committee. 7.2 INCENTIVE STOCK OPTIONS. Incentive Stock Options shall be granted only to employees and the terms of any Incentive Stock Options granted under the Plan must comply with the following additional rules: (a) EXERCISE PRICE. The exercise price per share of Stock shall be set by the Committee, provided that the exercise price for any Incentive Stock Option may not be less than the Fair Market Value as of the date of the grant. (b) EXERCISE. In no event, may any Incentive Stock Option be exercisable for more than ten years from the date of its grant. (c) LAPSE OF OPTION. An Incentive Stock Option shall lapse under the following circumstances. (1) The Incentive Stock Option shall lapse ten years from the date it is granted, unless an earlier time is set in the Award Agreement. (2) The Incentive Stock Option shall lapse upon termination of employment for Cause or for any other reason, other than the Participant's death or Disability, unless otherwise provided in the Award Agreement. (3) If the Participant terminates employment on account of Disability or death before the Option lapses pursuant to paragraph (1) or (2) above, the Incentive Stock Option shall lapse, unless it is previously exercised, on the earlier of (i) the date on which the Option would have lapsed had the Participant not become Disabled or lived 8

9 and had his employment status (i.e., whether the Participant was employed by the Company on the date of his Disability or death or had previously terminated employment) remained unchanged; or (ii) 12 months after the date of the Participant's termination of employment on account of Disability or death. Upon the Participant's Disability or death, any Incentive Stock Options exercisable at the Participant's Disability or death may be exercised by the Participant's legal representative or representatives, by the person or persons entitled to do so under the Participant's last will and testament, or, if the Participant fails to make testamentary disposition of such Incentive Stock Option or dies intestate, by the person or persons entitled to receive the Incentive Stock Option under the applicable laws of descent and distribution. (d) INDIVIDUAL DOLLAR LIMITATION. The aggregate Fair Market Value (determined as of the time an Award is made) of all shares of Stock with respect to which Incentive Stock Options are first exercisable by a Participant in any calendar year may not exceed $100,000.00 or such other limitation as imposed by Section 422(d) of the Code, or any successor provision. To the extent that Incentive Stock Options are first exercisable by a Participant in excess of such limitation, the excess shall be considered Non-Qualified Stock Options. (e) TEN PERCENT OWNERS. An Incentive Stock Option shall be granted to any individual who, at the date of grant, owns stock possessing more than ten percent of the total combined voting power of all classes of Stock of the Company only if such Option is granted at a price that is not less than 110% of Fair Market Value on the date of grant and the Option is exercisable for no more than five years from the date of grant. (f) EXPIRATION OF INCENTIVE STOCK OPTIONS. No Award of an Incentive Stock Option may be made pursuant to this Plan after the tenth anniversary of the Effective Date. (g) RIGHT TO EXERCISE. During a Participant's lifetime, an Incentive Stock Option may be exercised only by the Participant. ARTICLE 8 STOCK APPRECIATION RIGHTS 8.1 GRANT OF SARS. The Committee is authorized to grant SARs to Participants on the following terms and conditions: (a) RIGHT TO PAYMENT. Upon the exercise of a Stock Appreciation Right, the Participant to whom it is granted has the right to receive the excess, if any, of: (1) The Fair Market Value of a share of Stock on the date of exercise; over (2) The grant price of the Stock Appreciation Right as determined by the Committee, which shall not be less than the Fair Market Value of a share of Stock on the date of grant in the case of any SAR related to any Incentive Stock Option. 9

10 (b) OTHER TERMS. All awards of Stock Appreciation Rights shall be evidenced by an Award Agreement. The terms, methods of exercise, methods of settlement, form of consideration payable in settlement, and any other terms and conditions of any Stock Appreciation Right shall be determined by the Committee at the time of the grant of the Award and shall be reflected in the Award Agreement. ARTICLE 9 PERFORMANCE SHARES 9.1 GRANT OF PERFORMANCE SHARES. The Committee is authorized to grant Performance Shares to Participants on such terms and conditions as may be selected by the Committee. The Committee shall have the complete discretion to determine the number of Performance Shares granted to each Participant. All Awards of Performance Shares shall be evidenced by an Award Agreement. 9.2 RIGHT TO PAYMENT. A grant of Performance Shares gives the Participant rights, valued as determined by the Committee, and payable to, or exercisable by, the Participant to whom the Performance Shares are granted, in whole or in part, as the Committee shall establish at grant or thereafter. Subject to the terms of the Plan, the Committee shall set performance goals and other terms or conditions to payment of the Performance Shares in its discretion which, depending on the extent to which they are met, will determine the number and value of Performance Shares that will be paid to the Participant. 9.3 OTHER TERMS. Performance Shares may be payable in cash, Stock, or other property, and have such other terms and conditions as determined by the Committee and reflected in the Award Agreement. ARTICLE 10 RESTRICTED STOCK AWARDS 10.1 GRANT OF RESTRICTED STOCK. The Committee is authorized to make Awards of Restricted Stock to Participants in such amounts and subject to such terms and conditions as determined by the Committee. All Awards of Restricted Stock shall be evidenced by a Restricted Stock Award Agreement. 10.2 ISSUANCE AND RESTRICTIONS. Restricted Stock shall be subject to such restrictions on transferability and other restrictions as the Committee may impose (including, without limitation, limitations on the right to vote Restricted Stock or the right to receive dividends on the Restricted Stock). These restrictions may lapse separately or in combination at such times, under such circumstances, in such installments, or otherwise, as the Committee determines at the time of the grant of the Award or thereafter. 10.3 FORFEITURE. Except as otherwise determined by the Committee at the time of the grant of the Award or thereafter, upon termination of employment during the applicable restriction period, Restricted Stock that is at that time subject to restrictions shall be forfeited, provided, however, that the Committee may provide in any Restricted Stock Award Agreement that restrictions or forfeiture conditions relating to Restricted Stock will be waived in whole or in 10

11 part in the event of terminations resulting from specified causes, and the Committee may in other cases waive in whole or in part restrictions or forfeiture conditions relating to Restricted Stock. 10.4 CERTIFICATES FOR RESTRICTED STOCK. Restricted Stock granted under the Plan may be evidenced in such manner as the Committee shall determine. If certificates representing shares of Restricted Stock are registered in the name of the Participant, certificates must bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Restricted Stock, and the Company may, at its discretion, retain physical possession of the certificate until such time as all applicable restrictions lapse. ARTICLE 11 PERFORMANCE-BASED AWARDS 11.1 PURPOSE. The purpose of this Article 11 is to provide the Committee the ability to qualify the Performance Share Awards under Article 9 and the Restricted Stock Awards under Article 10 as "performance-based compensation" under Section 162(m) of the Code. If the Committee, in its discretion, decides to grant a Performance-Based Award to a Covered Employee, the provisions of this Article 11 shall control over any contrary provision contained in Articles 9 or 10. 11.2 APPLICABILITY. This Article 11 shall apply only to those Covered Employees selected by the Committee to receive Performance-Based Awards. The Committee may, in its discretion, grant Restricted Stock Awards or Performance Share Awards to Covered Employees that do not satisfy the requirements of this Article 11. The designation of a Covered Employee as a Participant for a Performance Period shall not in any manner entitle the Participant to receive an Award for the period. Moreover, designation of a Covered Employee as a Participant for a particular Performance Period shall not require designation of such Covered Employee as a Participant in any subsequent Performance Period and designation of one Covered Employee as a Participant shall not require designation of any other Covered Employees as a Participant in such period or in any other period. 11.3 DISCRETION OF COMMITTEE WITH RESPECT TO PERFORMANCE AWARDS. With regard to a particular Performance Period, the Committee shall have full discretion to select the length of such Performance Period, the type of Performance-Based Awards to be issued, the kind and/or level of the Performance Goal, and whether the Performance Goal is to apply to the Company, a Subsidiary or any division or business unit thereof. 11.4 PAYMENT OF PERFORMANCE AWARDS. Unless otherwise provided in the relevant Award Agreement, a Participant must be employed by the Company or a Subsidiary on the last day of the Performance Period to be eligible for a Performance Award for such Performance Period. Furthermore, a Participant shall be eligible to receive payment under a Performance-Based Award for a Performance Period only if the Performance Goals for such period are achieved. In determining the actual size of an individual Performance-Based Award, the Committee may reduce or eliminate the amount of the Performance-Based Award earned for the Performance Period, if in its sole and absolute discretion, such reduction or elimination is appropriate. 11

12 11.5 MAXIMUM AWARD PAYABLE. The maximum Performance-Based Award payable to any one Participant under the Plan for a Performance Period is 1,000,000 shares of Stock, or in the event the Performance-Based Award is paid in cash, such maximum Performance-Based Award shall be determined by multiplying 1,000,000 by the Fair Market Value of one share of Stock as of the date of grant of the Performance-Based Award. ARTICLE 12 TAKE OWNERSHIP GRANTS 12.1 TAKE OWNERSHIP GRANTS. The Take Ownership Grants shall be awarded to Participants selected by the Committee and shall be subject to the following terms and conditions: (a) EFFECTIVE DATE OF GRANTS. The effective date of the Take Ownership Grants shall be on the day on which the Company's initial public offering of Stock is consummated; provided, however, that Take Ownership Grants shall not be made to those persons who are not United States residents if the jurisdiction in which any such person resides prohibits such Grants or makes it impractical for the Company to make such Grants. (b) EXERCISE PRICE FOR GRANTS. Notwithstanding any other provision hereof, the exercise price per share of Stock under the Take Ownership Grants shall be the price at which the Company's Stock is offered under its initial public offering of Stock ("IPO Price"), provided, however, that, with respect to Participants who do not reside in the United States, if the day on which the Company receives approval by the applicable foreign jurisdiction to offer Stock to Participants residing in that jurisdiction is later than the day on which the Company's initial public offering becomes effective, the exercise price per share of Stock under the Take Ownership Grants shall be the Fair Market Value on the day on which the Company receives approval by the applicable foreign jurisdiction to offer Stock to such Participants. (c) AMOUNT OF THE TAKE OWNERSHIP GRANTS. Each Participant selected to receive a Take Ownership Grant shall be entitled to receive an Option to purchase 50 shares of Stock. Such Option shall be designated as a Non-Qualified Stock Option. (d) TIME AND CONDITIONS OF EXERCISE. The Take Ownership Grants shall become fully exercisable on the second anniversary of the date of grant. (e) PAYMENT. The Committee shall determine the methods by which the exercise price of the Take Ownership Grants may be paid, the form of payment, including, without limitation, cash, promissory note, shares of Stock (through actual tender or by attestation), or other property (including broker-assisted "cashless exercise" arrangements), and the methods by which shares of Stock shall be delivered or deemed to be delivered to Participants. (f) EVIDENCE OF GRANT. All Take Ownership Grants shall be evidenced by a written Award Agreement between the Company and the Participant. The Award Agreement shall provide that upon a Participant's termination of employment or service with the Company or a Subsidiary for any reason, the Participant may, at any time within 90 days after the effective date of the Participant's termination, exercise the Take Ownership Grant to the 12

13 extent that the Participant was entitled to exercise the Take Ownership Grant at the date of termination, provided that in no event shall the Take Ownership Grant be exercisable after its expiration date, as provided in the Award Agreement. The Award Agreement shall also include such other provisions as determined by the Committee. ARTICLE 13 PROVISIONS APPLICABLE TO AWARDS 13.1 STAND-ALONE AND TANDEM AWARDS. Awards granted under the Plan may, in the discretion of the Committee, be granted either alone, in addition to, or in tandem with, any other Award granted under the Plan. Awards granted in addition to or in tandem with other Awards may be granted either at the same time as or at a different time from the grant of such other Awards. 13.2 EXCHANGE PROVISIONS. The Committee may at any time offer to exchange or buy out any previously granted Award for a payment in cash, Stock, or another Award, based on the terms and conditions the Committee determines and communicates to the Participant at the time the offer is made. 13.3 TERM OF AWARD. The term of each Award shall be for the period as determined by the Committee, provided that in no event shall the term of any Incentive Stock Option or a Stock Appreciation Right granted in tandem with the Incentive Stock Option exceed a period of ten years from the date of its grant. 13.4 FORM OF PAYMENT FOR AWARDS. Subject to the terms of the Plan and any applicable law or Award Agreement, payments or transfers to be made by the Company or a Subsidiary on the grant or exercise of an Award may be made in such forms as the Committee determines at or after the time of grant, including without limitation, cash, promissory note, Stock, other Awards, or other property, or any combination, and may be made in a single payment or transfer, in installments, or on a deferred basis, in each case determined in accordance with rules adopted by, and at the discretion of, the Committee. 13.5 LIMITS ON TRANSFER. No right or interest of a Participant in any Award may be pledged, encumbered, or hypothecated to or in favor of any party other than the Company or a Subsidiary, or shall be subject to any lien, obligation, or liability of such Participant to any other party other than the Company or a Subsidiary. Except as otherwise provided by the Committee, no Award shall be assignable or transferable by a Participant other than by will or the laws of descent and distribution. 13.6 BENEFICIARIES. Notwithstanding Section 13.5, a Participant may, in the manner determined by the Committee, designate a beneficiary to exercise the rights of the Participant and to receive any distribution with respect to any Award upon the Participant's death. A beneficiary, legal guardian, legal representative, or other person claiming any rights under the Plan is subject to all terms and conditions of the Plan and any Award Agreement applicable to the Participant, except to the extent the Plan and Award Agreement otherwise provide, and to any additional restrictions deemed necessary or appropriate by the Committee. If 13

14 the Participant is married, a designation of a person other than the Participant's spouse as his beneficiary with respect to more than 50% of the Participant's interest in the Award shall not be effective without the written consent of the Participant's spouse. If no beneficiary has been designated or survives the Participant, payment shall be made to the person entitled thereto under the Participant's will or the laws of descent and distribution. Subject to the foregoing, a beneficiary designation may be changed or revoked by a Participant at any time provided the change or revocation is filed with the Committee. 13.7 STOCK CERTIFICATES. Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any certificates evidencing shares of Stock pursuant to the exercise of any Awards, unless and until the Board has determined, with advice of counsel, that the issuance and delivery of such certificates is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any exchange on which the shares of Stock are listed or traded. All Stock certificates delivered under the Plan are subject to any stop-transfer orders and other restrictions as the Committee deems necessary or advisable to comply with Federal, state, or foreign jurisdiction, securities or other laws, rules and regulations and the rules of any national securities exchange or automated quotation system on which the Stock is listed, quoted, or traded. The Committee may place legends on any Stock certificate to reference restrictions applicable to the Stock. In addition to the terms and conditions provided herein, the Board may require that a Participant make such reasonable covenants, agreements, and representations as the Board, in its discretion, deems advisable in order to comply with any such laws, regulations, or requirements. 13.8 ACCELERATION UPON A CHANGE OF CONTROL. At the time of the grant of an Option, Stock Appreciation Right or other Award or any time thereafter, the Board shall have the authority and discretion, but shall not have any obligation, to provide for the acceleration of the vesting and exercisability of any outstanding Option, Stock Appreciation Right or other Award upon a Change in Control. ARTICLE 14 CHANGES IN CAPITAL STRUCTURE 14.1 GENERAL. (a) SHARES AVAILABLE FOR GRANT. In the event of any change in the number of shares of Stock outstanding by reason of any stock dividend or split, recapitalization, merger, consolidation, combination or exchange of shares or similar corporate change, the maximum aggregate number of shares of Stock with respect to which the Committee may grant Awards shall be appropriately adjusted by the Committee. In the event of any change in the number of shares of Stock outstanding by reason of any other event or transaction, the Committee may, but need not, make such adjustments in the number and class of shares of Stock with respect to which Awards may be granted as the Committee may deem appropriate. (b) OUTSTANDING AWARDS - INCREASE OR DECREASE IN ISSUED SHARES WITHOUT CONSIDERATION. Subject to any required action by the shareholders of the Company, in the event of any increase or decrease in the number of issued shares of Stock resulting from a subdivision or consolidation of shares of Stock or the payment of a stock 14

15 dividend (but only on the shares of Stock), or any other increase or decrease in the number of such shares effected without receipt or payment of consideration by the Company, the Committee shall proportionally adjust the number of shares of Stock subject to each outstanding Award and the exercise price per share of Stock of each such Award. (c) OUTSTANDING AWARDS - CERTAIN MERGERS. Subject to any required action by the shareholders of the Company, in the event that the Company shall be the surviving corporation in any merger or consolidation (except a merger or consolidation as a result of which the holders of shares of Stock receive securities of another corporation), each Award outstanding on the date of such merger or consolidation shall pertain to and apply to the securities which a holder of the number of shares of Stock subject to such Award would have received in such merger or consolidation. (d) OUTSTANDING AWARDS - CERTAIN OTHER TRANSACTIONS. In the event of (i) a dissolution or liquidation of the Company, (ii) a sale of all or substantially all of the Company's assets, (iii) a merger or consolidation involving the Company in which the Company is not the surviving corporation or (iv) a merger or consolidation involving the Company in which the Company is the surviving corporation but the holders of shares of Stock receive securities of another corporation and/or other property, including cash, the Committee shall, in its absolute discretion, have the power to: (1) cancel, effective immediately prior to the occurrence of such event, each Award outstanding immediately prior to such event (whether or not then exercisable), and, in full consideration of such cancellation, pay to the Participant to whom such Award was granted an amount in cash, for each share of Stock subject to such Award, respectively, equal to the excess of (A) the value, as determined by the Committee in its absolute discretion, of the property (including cash) received by the holder of a share of Stock as a result of such event over (B) the exercise of such Award; or (2) provide for the exchange of each Award outstanding immediately prior to such event (whether or not then exercisable) for an option, a stock appreciation right, restricted stock award, performance share award or performance-based award with respect to, as appropriate, some or all of the property for which such Award is exchanged and, incident thereto, make an equitable adjustment as determined by the Committee in its absolute discretion in the exercise price or value of the option, stock appreciate right, restricted stock award, performance share award or performance-based award or the number of shares or amount of property subject to the option, stock appreciation right, restricted stock award, performance share award or performance-based award or, if appropriate, provide for a cash payment to the Participant to whom such Award was granted in partial consideration for the exchange of the Award. (e) OUTSTANDING AWARDS - OTHER CHANGES. In the event of any other change in the capitalization of the Company or corporate change other than those specifically referred to in Article 14, the Committee may, in its absolute discretion, make such adjustments in the number and class of shares subject to Awards outstanding on the date on 15

16 which such change occurs and in the per share exercise price of each Award as the Committee may consider appropriate to prevent dilution or enlargement of rights. (f) NO OTHER RIGHTS. Except as expressly provided in the Plan, no Participant shall have any rights by reason of any subdivision or consolidation of shares of stock of any class, the payment of any dividend, any increase or decrease in the number of shares of stock of any class or any dissolution, liquidation, merger, or consolidation of the Company or any other corporation. Except as expressly provided in the Plan, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number of shares of Stock subject to an Award or the exercise price of any Award. ARTICLE 15 AMENDMENT, MODIFICATION, AND TERMINATION 15.1 AMENDMENT, MODIFICATION, AND TERMINATION. With the approval of the Board, at any time and from time to time, the Committee may terminate, amend or modify the Plan; provided, however, that to the extent necessary and desirable to comply with any applicable law, regulation, or stock exchange rule, the Company shall obtain shareholder approval of any Plan amendment in such a manner and to such a degree as required. 15.2 AWARDS PREVIOUSLY GRANTED. Except as otherwise provided in the Plan, including without limitation, the provisions of Article 14, no termination, amendment, or modification of the Plan shall adversely affect in any material way any Award previously granted under the Plan, without the written consent of the Participant. ARTICLE 16 PROVISIONS RELATING TO FRENCH EMPLOYEES Notwithstanding any other provisions of the Plan to the contrary, the following provisions shall apply to Awards granted to any employee who is a French citizen or who works primarily in France as of the grant date (referred to herein as "French Employee"). 16.1 CONSULTANTS. Notwithstanding anything to the contrary herein, no French Employee who would otherwise be considered a consultant under French law may be granted an Award under the Plan. 16.2 TERMINATION FOR CAUSE. The last sentence of Section 3.1(d) (definition of Cause) shall not apply to French Employees. 16.3 TEN PERCENT OWNERS.

No Options shall be granted to any French Employee five years after the later of (a) the date the Company's stockholders initially approved the Plan, or (b) the date the Plan has been subsequently re-authorized, in its original form or as amended from time to time by the Board, by the Company's stockholders. 16.6 VESTING OF OPTIONS. Notwithstanding Section 7.1(b) above, no portion of any Award granted to a French Employee shall become exercisable before the five-year anniversary of the grant date. 16.7 EFFECT OF PARTICIPANT'S DEATH. Notwithstanding Section 7.1(b) or any other provision hereof, upon a French Employee's death, the vested portion of such Participant's Award shall remain exercisable for a period of six months after the date of his death and shall be exercisable by his heirs. 16.8 EXCHANGE OF OPTIONS. Notwithstanding Section 13.2 above, the Company shall not terminate any portion of an Award granted to any French Employee. 16.9 ADJUSTMENT OF OPTIONS. Notwithstanding Section 14.1 herein, any adjustment made to any Award granted to a French Employee shall comply with applicable French law. ARTICLE 17 GENERAL PROVISIONS 17.1 NO RIGHTS TO AWARDS. No Participant, employee, or other person shall have any claim to be granted any Award under the Plan, and neither the Company nor the Committee is obligated to treat Participants, employees, and other persons uniformly. 17.2 NO STOCKHOLDERS RIGHTS. No Award gives the Participant any of the rights of a stockholder of the Company unless and until shares of Stock are in fact issued to such person in connection with such Award. 17.3 WITHHOLDING. The Company or any Subsidiary shall have the authority and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy Federal, state, and local taxes (including the Participant's FICA obligation) required by law to be withheld with respect to any taxable event arising as a result of this Plan. With the Committee's consent, a Participant may elect to have the Company withhold from those Stock that would otherwise be received upon the exercise of any Option, a number of shares having a Fair Market Value equal to the minimum statutory amount necessary to satisfy the Company's applicable federal, state, local and foreign income and employment tax withholding obligations. 17.4 NO RIGHT TO EMPLOYMENT OR SERVICES. Nothing in the Plan or any Award Agreement shall interfere with or limit in any way the right of the Company or any Subsidiary to terminate any Participant's employment or services at any time, nor confer upon any Participant any right to continue in the employ of the Company or any Subsidiary. 17

18 17.5 UNFUNDED STATUS OF AWARDS. The Plan is intended to be an "unfunded" plan for incentive compensation. With respect to any payments not yet made to a Participant pursuant to an Award, nothing contained in the Plan or any Award Agreement shall give the Participant any rights that are greater than those of a general creditor of the Company or any Subsidiary. 17.6 INDEMNIFICATION. To the extent allowable under applicable law, each member of the Committee or of the Board shall be indemnified and held harmless by the Company from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by such member in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action or failure to act under the Plan and against and from any and all amounts paid by him or her in satisfaction of judgment in such action, suit, or proceeding against him or her provided he or she gives the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company's Articles of Incorporation or Bylaws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless. 17.7 RELATIONSHIP TO OTHER BENEFITS. No payment under the Plan shall be taken into account in determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any Subsidiary. 17.8 EXPENSES. The expenses of administering the Plan shall be borne by the Company and its Subsidiaries. 17.9 TITLES AND HEADINGS. The titles and headings of the Sections in the Plan are for convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control. 17.10 FRACTIONAL SHARES. No fractional shares of stock shall be issued and the Committee shall determine, in its discretion, whether cash shall be given in lieu of fractional shares or whether such fractional shares shall be eliminated by rounding up or down as appropriate. 17.11 SECURITIES LAW COMPLIANCE. With respect to any person who is, on the relevant date, obligated to file reports under Section 16 of the Exchange Act, transactions under this Plan are intended to comply with all applicable conditions of Rule 16b-3 or its successors under the Exchange Act. To the extent any provision of the Plan or action by the Committee fails to so comply, it shall be void to the extent permitted by law and voidable as deemed advisable by the Committee. 17.12 GOVERNMENT AND OTHER REGULATIONS. The obligation of the Company to make payment of awards in Stock or otherwise shall be subject to all applicable laws, rules, and regulations, and to such approvals by government agencies as may be required. The Company shall be under no obligation to register under the Securities Act of 1933, as 18

19 amended, any of the shares of Stock paid under the Plan. If the shares paid under the Plan may in certain circumstances be exempt from registration under the Securities Act of 1933, as amended, the Company may restrict the transfer of such shares in such manner as it deems advisable to ensure the availability of any such exemption. 17.13 GOVERNING LAW. The Plan and all Award Agreements shall be construed in accordance with and governed by the laws of the State of Delaware. 19

1 EXHIBIT 4.2 ON SEMICONDUCTOR CORPORATION (FORMERLY KNOWN AS SCG HOLDING CORPORATION) 2000 EMPLOYEE STOCK PURCHASE PLAN (AS ADOPTED BY THE BOARD OF DIRECTORS ON FEBRUARY 17, 2000; AMENDED AND RESTATED APRIL 21, 2000; AMENDED AND RESTATED MAY 23, 2001) 1. PURPOSE. The purpose of this SCG Holding Corporation 2000 Employee Stock Purchase Plan (the "Plan") is to encourage stock ownership by eligible employees of SCG Holding Corporation (the "Company") and its Subsidiaries and thereby provide employees with an incentive to contribute to the profitability and success of the Company. The Plan is intended to qualify as an "employee stock purchase plan" under Section 423 of the Code and will be maintained for the exclusive benefit of eligible employees of the Company and its Subsidiaries. 2. DEFINITIONS. For purposes of the Plan, in addition to the terms defined in Section 1, the following terms are defined: (a) "Board" means the Board of Directors of the Company. (b) "Cash Account" means the account maintained on behalf of a Participant by the Company for the purpose of holding cash contributions withheld from payroll pending investment in Stock. (c) "Code" means the Internal Revenue Code of 1986, as amended. (d) "Custodian" means Solomon Smith Barney or any successor or replacement appointed by the Board or its delagatee under Section 3(a). (e) "Earnings" means a Participant's salary or wages, including bonuses, for services performed for the Company and its Subsidiaries and received by a Participant for services rendered during an Offering Period. (f) "Fair Market Value" means the closing price of the Stock on the relevant date as reported on NASDAQ (or any national securities exchange or quotation system on which the Stock is then listed), or if there were no sales on that date the closing price on the next preceding date for which a closing price was reported; provided, however, that for any Offering Period beginning on the IPO Date, the Fair Market Value of the Stock on the first day of such Offering Period shall be deemed to be the price at which the Company's Stock is offered under its initial public offering of Stock. (g) "IPO Date" means the date on which the Company's initial public offering of Stock is consummated. (h) "Offering Period" means the period beginning on the IPO Date and ending on the last day of the next calendar quarter, and every three-month period thereafter. For 1

2 Participants who do not reside in the United States, if the day on which the Company receives approval by the applicable foreign jurisdiction to offer common stock to Participants residing in that jurisdiction is later than the day on which the Company's initial public offering becomes effective, the Offering Period means the period beginning on the day on which the Company receives approval by the applicable foreign jurisdiction to offer common stock to such Participants and ending on the last day of the next calendar quarter, and every three-month period thereafter. (i) "Participant" means an employee of the Company or a Subsidiary who is participating in the Plan. (j) "Purchase Right" means a Participant's option to purchase Stock that is deemed to be outstanding during an Offering Period. A Purchase Right represents an "option" under Section 423 of the Code. (k) "Stock" means the common stock of the Company. (l) "Stock Account" means the account maintained on behalf of the Participant by the Custodian for the purpose of holding Stock acquired under the Plan. (m) "Subsidiary" means any corporation (other than the Company) in an unbroken chain of corporations beginning with the Company if each of the corporations (other than the last corporation in the unbroken chain) owns stock possessing 50% or more of the total combined voting power of all classes of stock in one of the other corporations in the chain as set forth in Code Section 424(f). 3. ADMINISTRATION. (a) Board Administration. The Plan will be administered by the Board. The Board may delegate its administrative duties and authority (other than its authority to amend the Plan) to any Board committee or to any officers or employees or committee thereof as the Board may designate (in which case references to the Board will be deemed to refer to the administrator to which such duties and authority have been delegated). The Board will have full authority to adopt, amend, suspend, waive, and rescind rules and regulations and appoint agents as it deems necessary or advisable to administer the Plan, to correct any defect or supply any omission or reconcile any inconsistency in the Plan and to construe and interpret the Plan and rules and regulations thereunder, to furnish to the Custodian such information as the Custodian may require, and to make all other decisions and determinations under the Plan (including determinations relating to eligibility). No person acting in connection with the administration of the Plan will, in that capacity, participate in deciding any matter relating to his or her participation in the Plan. (b) The Custodian. The Custodian will act as custodian under the Plan, and will perform duties under the Plan and in any agreement between the Company and the Custodian. The Custodian will establish and maintain Participants Stock Accounts and any subaccounts as may be necessary or desirable to administer the Plan. 2

3 (c) Waivers. The Board may waive or modify any requirement that a notice or election be made or filed under the Plan a specified period in advance on an individual case or by adopting a rule or regulation under the Plan, without amending the Plan. (d) Other Administrative Provisions. The Company will furnish information from its records as directed by the Board, and such records, including a Participant's Earnings, will be conclusive on all persons unless determined by the Board to be incorrect. Each Participant and other person claiming benefits under the Plan must furnish to the Company in writing an up-to-date mailing address and any other information as the Board or Custodian may reasonably request. Any communication, statement, or notice mailed with postage prepaid to any such Participant or other person at the last mailing address filed with the Company will be deemed sufficiently given when mailed and will be binding upon the named recipient. The Plan will be administered on a reasonable and nondiscriminatory basis and uniform rules will apply to all persons similarly situated. All Participants will have equal rights and privileges (subject to the terms of the Plan) with respect to Purchase Right outstanding during any given Offering Period in accordance with Code Section 423(b)(5). 4. STOCK SUBJECT TO PLAN. Subject to adjustment as provided below, the total number of shares of Stock reserved and available for issuance or which may be otherwise acquired upon exercise of Purchase Rights under the Plan will be 5,500,000. If, at the end of any Offering Period, the number of shares of Stock with respect to which Purchase Rights are to be exercised exceeds the number of shares of Stock then available under the Plan, the Board shall make a pro rata allocation of the shares of Stock remaining available for purchase in as uniform a manner as shall be practicable and as it shall determine to be equitable. Any shares of Stock delivered by the Company under the Plan may consist, in whole or in part, of authorized and unissued shares or treasury shares or shares of Stock purchased on the open market. The number and kind of such shares of Stock subject to the Plan will be proportionately adjusted, as determined by the Board, in the event of any extraordinary dividend or other distribution, recapitalization, forward or reverse split, reorganization, merger, consolidation, spin-off, combination, repurchase, or share exchange, or other similar corporate transaction or event affecting the Stock. 5. ENROLLMENT AND CONTRIBUTIONS. (a) Eligibility. An employee of the Company or any Subsidiary designated by the Board may be enrolled in the Plan for any Offering Period if such employee is employed by the Company or a Subsidiary authorized to participate in the Plan on the first day of the Offering Period, unless one of the following applies to the employee: (i) such person has been employed by the Company or a Subsidiary less than 90 days; or (ii) such person is customarily employed by the Company or a Subsidiary for 20 hours or less a week; or 3

4 (iii) such person is customarily employed by the Company or a Subsidiary for not more than five months in any calendar year; (iv) such person would, immediately upon enrollment, be deemed to own, for purposes of Section 423(b)(3) of the Code, an aggregate of five percent or more of the total combined voting power or value of all outstanding shares of all classes of the Stock of the Company or any Subsidiary. Notwithstanding the above, solely for purposes of the first Offering Period under the Plan, an employee who is employed by the Company or a Subsidiary on the first day of such Offering Period and who is otherwise eligible to participate in the Plan shall not be required to satisfy the 90 day employment period specified in 5(a)(i) above. The Company will notify an employee of the date as of which he or she is eligible to enroll in the Plan, and will make available to each eligible employee the necessary enrollment forms. Notwithstanding the above, any individual who is employed by the Company or a Subsidiary designated by the Board and who is working outside of the United States shall not be eligible to participate in the Plan if the laws of the country in which the employee is working makes the offer of the Purchase Right or the delivery of Stock under the Plan impractical. Additionally, the offer of the Purchase Right and the delivery of Stock under the Plan shall be effective for any individual who is employed by the Company or a Subsidiary and who is working outside of the United States only after the Company has complied with the applicable laws of the country in which the employee is working. (b) Initial Enrollment. An employee who is eligible under Section 5(a) (or who will become eligible on or before a given Offering Period) may, after receiving current information about the Plan, initially enroll in the Plan by executing and filing with the Company a properly completed enrollment form, including the employee's election as to the rate of payroll contributions for the Offering Period. To be effective for any Offering Period, such enrollment form must be filed at least two weeks (or such other period determined by the Board) preceding such Offering Period. (c) Automatic Re-enrollment for Subsequent Offering Periods. A Participant whose enrollment in, and payroll contributions under, the Plan continues throughout a Offering Period will automatically be re-enrolled in the Plan for the next Offering Period unless (i) the Participant terminates enrollment before the next Offering Period in accordance with Section 7(a), or (ii) the Participant is ineligible to participate under Section 5(a). The initial rate of payroll contributions for a Participant who is automatically re-enrolled for a Offering Period will be the same as the rate of payroll contribution in effect at the end of the preceding Offering Period, unless the Participant files a new enrollment form designating a different rate of payroll contributions and such new enrollment form is received no later than two weeks (or such other period determined by the Board) prior to the beginning of the next Offering Period. (d) Payroll Contributions. A Participant will make contributions under the Plan by means of payroll deductions from each payroll period which ends during the Offering Period, 4

5 at the rate elected by the Participant in his or her enrollment form in effect for that Offering Period (except that such rate may be changed during the Offering Period to the extent permitted below). The rate of payroll contributions elected by a Participant may not be less than one percent (1%) nor more than ten percent (10%) of the Participant's Earnings for each payroll period, and only whole percentages may be elected; provided, however, that the Board may specify a lower minimum rate and higher maximum rate, subject to Section 8(c). Notwithstanding the above, a Participant's payroll contributions will be adjusted downward by the Company as necessary to ensure that the limit on the amount of Stock purchased for an Offering Period set forth in Section 6(a)(iii) is not exceeded. A Participant may elect to increase, decrease, or discontinue payroll contributions for a future Offering Period by filing a new enrollment form designating a different rate of payroll contributions, which form must be received at least two weeks (or such other period determined by the Board) prior to the beginning of an Offering Period to be effective for that Offering Period. In addition, a Participant may elect to discontinue payroll contributions during an Offering Period by filing a new enrollment form, such change to be effective for the next payroll after the Participant's new enrollment form is received. (e) Crediting Payroll Contributions to Cash Accounts. All payroll contributions by a Participant under the Plan will be credited to a Cash Account maintained by the Company on behalf of the Participant. The Company will credit payroll contributions to each Participant's Cash Account as soon as practicable after the contributions are withheld from the Participant's Earnings. (f) No Interest on Cash Accounts. No interest will be credited or paid on cash balances in Participant's Cash Accounts pending investment in Stock. 6. PURCHASES OF STOCK (a) Purchase Rights. Enrollment in the Plan for any Offering Period by a Participant will constitute a grant by the Company of a Purchase Right to such Participant for such Offering Period. Each Purchase Right will be subject to the following terms: (i) The purchase price of each share of Stock purchased for each Offering Period will equal 85% of the lesser of the Fair Market Value of a share of Stock on the first day of an Offering Period, or the Fair Market Value of a share of Stock on the last day of an Offering Period. (ii) Except as limited in (iii) below, the number of shares of Stock that may be purchased upon exercise of the Purchase Right for a Offering Period will equal the number of shares (including fractional shares) that can be purchased at the purchase price specified in Section 6(a)(i) with the aggregate amount credited to the Participant's Cash Account as of the last day of an Offering Period. 5

6 (iii) The number of shares of Stock subject to a Participant's Purchase Right for any Offering Period will not exceed the lesser of: (1) 500 shares of Stock, or (2) the number derived by dividing $6,250 by 100% of the Fair Market Value of one share of Stock on the first day of the Offering Period for the Offering Period. (iv) The Purchase Right will be automatically exercised on the last day of the Offering Period. (v) Payments by a Participant for Stock purchased under a Purchase Right will be made only through payroll deduction in accordance with Section 5(d) and (e). (vi) The Purchase Right will expire on the earlier of the last day of the Offering Period or the date on which the Participant's enrollment in the Plan terminates. (b) Purchase of Stock. At or as promptly as practicable after the last day of an Offering Period, amounts credited to each Participant's Cash Account will be applied by the Company to purchase Stock, in accordance with the terms of the Plan. Shares of Stock will be purchased from the Company or in the open market, as the Board determines. The Company will aggregate the amounts in all Cash Accounts when purchasing Stock, and shares purchased will be allocated to each Participant's Stock Account in proportion to the cash amounts withdrawn from such Participant's Cash Account. After completing purchases for each Offering Period (which will be completed in not more than 15 calendar days after the last day of an Offering Period), all shares of Stock so purchased for a Participant will be credited to the Participant's Stock Account. (c) Dividend Reinvestment; Other Distributions. Cash dividends on any Stock credited to a Participant's Stock Account will be automatically reinvested in additional shares of Stock; such amounts will not be available in the form of cash to Participants. The Company will aggregate all purchases of Stock in connection with dividend reinvestment for a given dividend payment date. Purchases of Stock for purposes of dividend reinvestment will be made as promptly as practicable (but not more than 15 calendar days) after a dividend payment date. The purchases will be made directly from the Company at 100% of the Fair Market Value of a share of Stock on the dividend payment date or on the open market. Any shares of Stock distributed as a dividend or distribution in respect of shares of Stock or in connection with a split of the Stock credited to a Participant's Stock Account will be credited to such Account. (d) Withdrawals and Transfers. Shares of Stock may be withdrawn from a Participant's Stock Account, in which case one or more certificates for whole shares may be issued in the name of, and delivered to, the Participant, with such Participant receiving cash in lieu of fractional shares based on the Fair Market Value of a share of Stock on the day preceding the date of withdrawal. Alternatively, whole shares of Stock may be withdrawn from a Participant's Stock Account by means of a transfer to a broker-dealer or financial institution that maintains an account for the Participant, together with the transfer of cash in lieu of fractional 6

7 shares based on the Fair Market Value of a share of Stock on the day preceding the date of withdrawal. Participants may not designate any other person to receive shares of Stock withdrawn or transferred under the Plan. A Participant seeking to withdraw or transfer shares of Stock must give instructions to the Custodian in such manner and form as may be prescribed by the Custodian, which instructions will be acted upon as promptly as practicable. Withdrawals and transfers will be subject to any fees imposed in accordance with Section 8(a). (e) Excess Account Balances. If any amounts remain in a Cash Account following the date on which the Company purchases Stock for an Offering Period as a result of the limitation set forth in Section 6(a)(iii) or for any other reason, such amounts will be returned to the Participant as promptly as practicable. 7. TERMINATION AND DISTRIBUTIONS. (a) Termination of Enrollment. A Participant's enrollment in the Plan will terminate upon (i) the beginning of any payroll period or Offering Period that begins after he or she files a written notice of termination of enrollment with the Company, provided that such Participant will continue to be deemed to be enrolled with respect to any completed Offering Period for which purchases have not been completed, (ii) such time as the Participant becomes ineligible to participate under Section 5(a) of the Plan, or (iii) the termination of the Participant's employment by the Company and its Subsidiaries. An employee whose enrollment in the Plan terminates may again enroll in the Plan as of any subsequent Offering Period that is at least 90 days after such termination of enrollment if he or she satisfies the eligibility requirements of Section 5(a) as of such Offering Period. A Participant's election to discontinue payroll contributions will not constitute a termination of enrollment. (b) Distribution. As soon as practicable after a Participant's enrollment in the Plan terminates, amounts in the Participant's Cash Account which resulted from payroll contributions will be repaid to the Participant. The Custodian will continue to maintain the Participant's Stock Account for the Participant until the earlier of such time as the Participant directs the sale of all Stock in the Account, withdraws, or transfers all Stock in the Account, or one year after the Participant ceases to be employed by the Company and its Subsidiaries. If a Participant's termination of enrollment results from his or her death, all amounts payable will be paid to his or her estate. 8. GENERAL. (a) Costs. Costs and expenses incurred in the administration of the Plan and maintenance of Accounts will be paid by the Company, to the extent provided in this Section 8(a). Any brokerage fees and commissions for the purchase of Stock under the Plan (including Stock purchased upon reinvestment of dividends and distributions) will be paid by the Company, but any brokerage fees and commissions for the sale of Stock under the Plan by a Participant will be borne by such Participant. The rate at which such fees and commissions will be charged to Participants will be determined by the Custodian or any broker-dealer used by the Custodian (including an affiliate of the Custodian), and communicated from time to time to Participants. In addition, the Custodian may impose or pass through a reasonable fee for the withdrawal of Stock 7

8 in the form of stock certificates (as permitted under Section 6(d)), and reasonable fees for other services unrelated to the purchase of Stock under the Plan, to the extent approved in writing by the Company and communicated to Participants. (b) Statements to Participants. The Participant's statement will reflect payroll contributions, purchases, sales, and withdrawals and transfers of shares of Stock and other Plan transactions by appropriate adjustments to the Participant's Accounts. The Custodian will, not less frequently than quarterly, provide or cause to be provided a written statement to the Participant showing the transactions in his or her Stock Account and the date thereof, the number of shares of Stock credited or sold, the aggregate purchase price paid or sales price received, the purchase or sales price per share, the brokerage fees and commissions paid (if any), the total shares held for the Participant's Stock Account (computed to at least three decimal places), and such other information as agreed to by the Custodian and the Company. (c) Compliance with Section 423. It is the intent of the Company that this Plan comply in all respects with applicable requirements of Section 423 of the Code and regulations thereunder. Accordingly, if any provision of this Plan does not comply with such requirements, such provision will be construed or deemed amended to the extent necessary to conform to such requirements. 9. GENERAL PROVISIONS. (a) Compliance With Legal and Other Requirements. The Plan, the granting and exercising of Purchase Rights hereunder, and the other obligations of the Company and the Custodian under the Plan will be subject to all applicable federal and state laws, rules, and regulations, and to such approvals by any regulatory or governmental agency as may be required. The Company may, in its discretion, postpone the issuance or delivery of Stock upon exercise of Purchase Rights until completion of such registration or qualification of such Stock or other required action under any federal or state law, rule, or regulation, or the laws of any country in which employees of the Company and a Subsidiary who are nonresident aliens and who are eligible to participate reside, or other required action with respect to any automated quotation system or stock exchange upon which the Stock or other Company securities are designated or listed, or compliance with any other contractual obligation of the Company, as the Company may consider appropriate. In addition, the Company may require any Participant to make such representations and furnish such information as it may consider appropriate in connection with the issuance or delivery of Stock in compliance with applicable laws, rules, and regulations, designation or listing requirements, or other contractual obligations. (b) Limits on Encumbering Rights. No right or interest of a Participant under the Plan, including any Purchase Right, may be pledged, encumbered, or hypothecated to or in favor of any party, subject to any lien, obligation, or liability of such Participant, or otherwise assigned, transferred, or disposed of except pursuant to the laws of descent or distribution, and any right of a Participant under the Plan will be exercisable during the Participant's lifetime only by the Participant. 8

9 (c) No Right to Continued Employment. Neither the Plan nor any action taken hereunder, including the grant of a Purchase Right, will be construed as giving any employee the right to be retained in the employ of the Company or any of its Subsidiaries, nor will it interfere in any way with the right of the Company or any of its Subsidiaries to terminate any employee's employment at any time. (d) Taxes. The Company or any Subsidiary is authorized to withhold from any payment to be made to a Participant, including any payroll and other payments not related to the Plan, amounts of withholding and other taxes due in connection with any transaction under the Plan, and a Participant's enrollment in the Plan will be deemed to constitute his or her consent to such withholding. In addition, Participants may be required to advise the Company of sales and other dispositions of Stock acquired under the plan in order to permit the Company to comply with tax laws and to claim any tax deductions to which the Company may be entitled with respect to the Plan. This provision and other Plan provisions do not set forth an explanation of the tax consequences to Participants under the Plan. A brief summary of the tax consequences will be included in disclosure documents to be separately furnished to Participants. (e) Changes to the Plan. The Board may amend, alter, suspend, discontinue, or terminate the Plan without the consent of shareholders or Participants, except that any such action will be subject to the approval of the Company's shareholders within one year after such Board action if such shareholder approval is required by any federal or state law or regulation or the rules of any automated quotation system or stock exchange on which the Stock may then be quoted or listed, or if such shareholder approval is necessary in order for the Plan to continue to meet the requirements of Section 423 of the Code, and the Board may otherwise, in its discretion, determine to submit other such actions to shareholders for approval. However, without the consent of an affected Participant, no amendment, alteration, suspension, discontinuation, or termination of the Plan may materially and adversely affect the rights of such Participant with respect to outstanding Purchase Rights relating to any Offering Period that has been completed prior to such Board action. The foregoing notwithstanding, upon termination of the Plan the Board may (i) elect to terminate all outstanding Purchase Rights at such time as the Board may designate, and all amounts contributed to the Plan which remain in a Participant's Cash Account will be returned to the Participant (without interest) as promptly as practicable, or (ii) shorten the Offering Period to such period determined by the Board and use amounts credited to a Participant Cash Account to purchase Stock. (f) No Rights to Participate; No Shareholder Rights. No Participant or employee will have any claim to participate in the Plan with respect to Offering Periods that have not commenced, and the Company will have no obligation to continue the Plan. No Purchase Right will confer on any Participant any of the rights of a shareholder of the Company unless and until Stock is duly issued or transferred and delivered to the Participant (or credited to the Participant's Stock Account). (g) Fractional Shares. Unless otherwise determined by the Board, purchases of Stock under the Plan executed by the Custodian may result in the crediting of fractional shares of Stock to the Participant's Stock Account. Such fractional shares will be computed to at least three decimal places. Fractional shares will not, however, be issued by the Company, and 9

10 certificates representing fractional shares will not be delivered to Participants under any circumstances. (h) Plan Year. The Plan will operate on a plan year that begins on January 1 and ends December 31 in each year. (i) Governing Law. The validity, construction, and effect of the Plan and any rules and regulations relating to the Plan will be determined in accordance with the laws of the State of Arizona, without giving effect to principles of conflicts of laws, and applicable federal law. (j) Effective Date. The Plan will become effective on the IPO Date, subject to the Plan being approved by shareholders of the Company, at a meeting by a vote sufficient to meet the requirements of Section 423(b)(2) of the Code. If the Plan is not approved in accordance with Section 423(b)(2) of the Code, each Participant's Purchase Right shall be void and amounts credited to the Participant's Cash Account shall be promptly returned to the Participant. 10
