Inducement Incentive Plan (the “Inducement Plan”) are not issued or delivered by reason of (i) the expiration, termination, cancellation or forfeiture of such award (excluding Shares subject to an option cancelled upon settlement in Shares of a related tandem SAR or Shares subject to a tandem SAR cancelled upon exercise of a related option) or (ii) the settlement of such award in cash, then such Shares shall be available under this Plan, other than for grants of Incentive Stock Options under this Plan. Subject to the limit set forth above and to adjustment as provided in Section 5.7, the aggregate maximum number of Shares that may be issued pursuant to the exercise of Incentive Stock Options will be 25,000,000 Shares.

Notwithstanding anything in this Section 1.5 to the contrary, Shares subject to an award under this Plan or the Inducement Plan may not be made available for issuance under this Plan if such shares are: (i) shares that were subject to a Share-settled SAR and were not issued upon the net settlement or net exercise of such SAR, (ii) shares used to pay the exercise price of an option, (iii) shares delivered to or withheld by the Company to pay withholding taxes related to an award under this Plan or the Inducement Plan, or (iv) shares repurchased on the open market with the proceeds of an option exercise.

The number of Shares for awards under this Plan shall not be reduced by (i) the number of Shares subject to Substitute Awards or (ii) available shares under a stockholder approved plan of a company or other entity which was a party to a corporate transaction with the Company (as appropriately adjusted to reflect such corporate transaction) which become subject to awards granted under this Plan (subject to applicable stock exchange requirements).

Shares to be delivered under this Plan shall be made available from authorized and unissued Shares, or authorized and issued Shares reacquired and held as treasury shares or otherwise or a combination thereof.

2.1 Options. The Committee may, in its discretion, grant options to purchase Shares to such eligible persons as may be selected by the Committee. Each option, or portion thereof, that is not an Incentive Stock Option, shall be a Nonqualified Option. To the extent that the aggregate Fair Market Value (determined as of the date of grant) of Shares with respect to which options designated as Incentive Stock Options are exercisable for the first time by a participant during any calendar year (under this Plan or any other plan of the Company, or any parent or Subsidiary) exceeds the amount (currently $100,000) established by the Code, such options shall constitute Nonqualified Options.

Options shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with the terms of this Plan, as the Committee shall deem advisable:

(a) Number of Shares and Purchase Price. The number of Shares subject to an option and the purchase price per Share purchasable upon exercise of the option shall be determined by the Committee; provided, however, that the purchase price per Share purchasable upon exercise of an option shall not be less than 100% of the Fair Market Value of a Share on the date of grant of such option; provided further, that if an Incentive Stock Option shall be granted to any person who, at the time such option is granted, owns capital stock possessing more than 10 percent of the total combined voting power of all classes of capital stock of the Company (or of any parent or Subsidiary) (a “Ten Percent Holder”), the purchase price per Share shall not be less than the price (currently 110% of Fair Market Value) required by the Code in order to constitute an Incentive Stock Option.

6

Notwithstanding the foregoing, in the case of an option that is a Substitute Award, the purchase price per Share of the Shares subject to such option may be less than 100% of the Fair Market Value per Share on the date of grant, provided, that the excess of: (a) the aggregate Fair Market Value (as of the date such Substitute Award is granted) of the shares subject to the Substitute Award, over (b) the aggregate purchase price thereof does not exceed the excess of: (x) the aggregate fair market value (as of the time immediately preceding the transaction giving rise to the Substitute Award, such fair market value to be determined by the Committee) of the shares of the predecessor company or other entity that were subject to the grant assumed or substituted for by the Company, over (y) the aggregate purchase price of such shares.

(b) Option Period and Exercisability. The period during which an option may be exercised shall be determined by the Committee; provided, however, that no option shall be exercised later than ten years after its date of grant; provided further, that if an Incentive Stock Option shall be granted to a Ten Percent Holder, such option shall not be exercised later than five years after its date of grant. The Committee may, in its discretion, establish Performance Measures which shall be satisfied or met as a condition to the grant of an option or to the exercisability of all or a portion of an option. The Committee shall determine whether an option shall become exercisable in cumulative or non-cumulative installments and in part or in full at any time. An exercisable option, or portion thereof, may be exercised only with respect to whole Shares. Prior to the exercise of an option, the holder of such option shall have no rights as a stockholder of the Company with respect to the Shares subject to such option.

(c) Method of Exercise. An option may be exercised (i) by giving written notice to the Company specifying the number of whole Shares to be purchased and accompanying such notice with payment therefor in full (or arrangement made for such payment to the Company’s satisfaction) either (A) in cash, (B) by delivery (either actual delivery or by attestation procedures established by the Company) of Shares having a Fair Market Value, determined as of the date of exercise, equal to the aggregate purchase price payable by reason of such exercise, (C) authorizing the Company to withhold whole Shares which would otherwise be delivered having an aggregate Fair Market Value, determined as of the date of exercise, equal to the amount necessary to satisfy such obligation, (D) in cash by a broker-dealer acceptable to the Company to whom the optionee has submitted an irrevocable notice of exercise or (E) a combination of (A), (B) and (C), in each case to the extent set forth in the Agreement relating to the option, (ii) if applicable, by surrendering to the Company any Tandem SARs which are cancelled by reason of the exercise of the option and (iii) by executing such documents as the Company may reasonably request. Any fraction of a Share which would be required to pay such purchase price shall be disregarded and the remaining amount due shall be paid in cash by the optionee. No Shares shall be issued and no certificate representing Shares shall be delivered until the full purchase price therefor and any withholding taxes thereon, as described in Section 5.5, have been paid (or arrangement made for such payment to the Company’s satisfaction).

7

2.2 Share Appreciation Rights. The Committee may, in its discretion, grant SARs to such eligible persons as may be selected by the Committee. The Agreement relating to an SAR shall specify whether the SAR is a Tandem SAR or a Free-Standing SAR.

SARs shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with the terms of this Plan, as the Committee shall deem advisable:

(a) Number of SARs and Base Price. The number of SARs subject to an award shall be determined by the Committee. Any Tandem SAR related to an Incentive Stock Option shall be granted at the same time that such Incentive Stock Option is granted. The base price of a Tandem SAR shall be the purchase price per Share of the related option. The base price of a Free-Standing SAR shall be determined by the Committee; provided, however, that such base price shall not be less than 100% of the Fair Market Value of a Share on the date of grant of such SAR.

Notwithstanding the foregoing, in the case of an SAR that is a Substitute Award, the base price per Share of the Shares subject to such SAR may be less than 100% of the Fair Market Value per Share on the date of grant, provided, that the excess of: (a) the aggregate Fair Market Value (as of the date such Substitute Award is granted) of the Shares subject to the Substitute Award, over (b) the aggregate base price thereof does not exceed the excess of: (x) the aggregate fair market value (as of the time immediately preceding the transaction giving rise to the Substitute Award, such fair market value to be determined by the Committee) of the shares of the predecessor company or other entity that were subject to the grant assumed or substituted for by the Company, over (y) the aggregate base price of such shares.

(b) Exercise Period and Exercisability. The period for the exercise of an SAR shall be determined by the Committee; provided, however, that no Tandem SAR shall be exercised later than the expiration, cancellation, forfeiture or other termination of the related option and no Free-Standing SAR shall be exercised later than ten years after its date of grant. The Committee may, in its discretion, establish Performance Measures which shall be satisfied or met as a condition to the grant of an SAR or to the exercisability of all or a portion of an SAR. The Committee shall determine whether an SAR may be exercised in cumulative or non-cumulative installments and in part or in full at any time. An exercisable SAR, or portion thereof, may be exercised, in the case of a Tandem SAR, only with respect to whole Shares and, in the case of a Free-Standing SAR, only with respect to a whole number of SARs. If an SAR is exercised for shares of Restricted Shares, a certificate or certificates representing such Restricted Shares shall be issued in accordance with Section 3.3(c), or such shares shall be transferred to the holder in book entry form with restrictions on the Shares duly noted, and the holder of such Restricted Shares shall have such rights of a stockholder of the Company as determined pursuant to Section 3.3(d). Prior to the exercise of an SAR, the holder of such SAR shall have no rights as a stockholder of the Company with respect to the Shares subject to such SAR.

(c) Method of Exercise. A Tandem SAR may be exercised (i) by giving written notice to the Company specifying the number of whole SARs which are being exercised, (ii) by surrendering to the Company any options which are cancelled by reason of the exercise of the Tandem SAR and (iii) by executing such documents as the Company may reasonably request. A Free-Standing SAR may be exercised (A) by giving written notice to the Company specifying the whole number of SARs which are being exercised and (B) by executing such documents as the Company may reasonably request.

8

No Shares shall be issued and no certificate representing Shares shall be delivered until any withholding taxes thereon, as described in Section 5.5, have been paid (or arrangement made for such payment to the Company’s satisfaction).

2.3 Termination of Employment or Service. All of the terms relating to the exercise, cancellation or other disposition of an option or SAR (i) upon a termination of employment with or service to the Company of the holder of such option or SAR, as the case may be, whether by reason of disability, retirement, death or any other reason, or (ii) during a paid or unpaid leave of absence, shall be determined by the Committee and set forth in the applicable award Agreement.

2.4 Repricing of Options and SARs. The Committee may not amend or replace any previously granted option or SAR in a transaction that constitutes a repricing within the meaning of the rules of the Nasdaq Stock Exchange or any other stock exchange on which Shares are then traded, without prior approval of the stockholders of the Company.

3.1 Share Awards. The Committee may, in its discretion, grant Share Awards to such eligible persons as may be selected by the Committee. The Agreement relating to a Share Award shall specify whether the Share Award is a Bonus Share Award, Restricted Share Award or Restricted Share Unit Award.

3.2 Terms of Bonus Share Awards. The number of Shares subject to a Bonus Share Award shall be determined by the Committee. Bonus Share Awards shall not be subject to any Restriction Periods or Performance Measures.

9

(c) Share Issuance. During the Restriction Period, the Restricted Shares shall be held by a custodian in book entry form with restrictions on such Shares duly noted or, alternatively, a certificate or certificates representing a Restricted Share Award shall be registered in the holder’s name and may bear a legend, in addition to any legend which may be required pursuant to Section 5.6, indicating that the ownership of the Shares represented by such certificate is subject to the restrictions, terms and conditions of this Plan and the Agreement relating to the Restricted Share Award. All such certificates shall be deposited with the Company, together with stock powers or other instruments of assignment (including a power of attorney), each endorsed in blank with a guarantee of signature if deemed necessary or appropriate, which would permit transfer to the Company of all or a portion of the Shares subject to the Restricted Share Award in the event such award is forfeited in whole or in part. Upon termination of any applicable Restriction Period (and the satisfaction or attainment of applicable Performance Measures), subject to the Company’s right to require payment of any taxes in accordance with Section 5.5, the restrictions shall be removed from the requisite number of any Shares that are held in book entry form, and all certificates evidencing ownership of the requisite number of Shares shall be delivered to the holder of such award.

No award shall be valid until an Agreement is executed by the Company and, to the extent required by the Company, either executed by the recipient or accepted by the recipient by electronic means approved by the Company within the time period specified by the Company. Upon such execution or execution and electronic acceptance, and delivery of the Agreement to the Company, such award shall be effective as of the effective date set forth in the Agreement.

5.4 Non-Transferability. No award shall be transferable other than by will, the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company or, to the extent expressly permitted in the Agreement relating to such award, to the holder’s family members, a trust or entity established by the holder for estate planning purposes or a charitable organization designated by the holder, in each case, without consideration. Except to the extent permitted by the foregoing sentence or the Agreement relating to an award, each award may be exercised or settled during the holder’s lifetime only by the holder or the holder’s legal representative or similar person. Except as permitted by the second preceding sentence, no award may be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of any award, such award and all rights thereunder shall immediately become null and void.

12

5.5 Tax Withholding. The Company shall have the right to require, prior to the issuance or delivery of any Shares or the payment of any cash pursuant to an award made hereunder, payment by the holder of such award of any federal, state, local or other taxes which may be required to be withheld or paid in connection with such award. An Agreement may provide that (i) the Company shall withhold whole Shares which would otherwise be delivered to a holder, having an aggregate Fair Market Value determined as of the date the obligation to withhold or pay taxes arises in connection with an award (the “Tax Date”), or withhold an amount of cash which would otherwise be payable to a holder, in the amount necessary to satisfy any such obligation or (ii) the holder may satisfy any such obligation by any of the following means: (A) a cash payment to the Company, (B) delivery (either actual delivery or by attestation procedures established by the Company) to the Company of previously owned whole Shares having an aggregate Fair Market Value, determined as of the Tax Date, equal to the amount necessary to satisfy any such obligation, (C) authorizing the Company to withhold whole Shares which would otherwise be delivered having an aggregate Fair Market Value, determined as of the Tax Date, or withhold an amount of cash which would otherwise be payable to a holder, equal to the amount necessary to satisfy any such obligation, (D) in the case of the exercise of an option and except as may be prohibited by applicable law, a cash payment by a broker-dealer acceptable to the Company to whom the optionee has submitted an irrevocable notice of exercise or (E) any combination of (A), (B) and (C), in each case to the extent set forth in the Agreement relating to the award. Shares to be delivered or withheld may not have an aggregate Fair Market Value in excess of the amount determined by applying the minimum statutory withholding rate. Any fraction of a Share which would be required to satisfy such an obligation shall be disregarded and the remaining amount due shall be paid in cash by the holder.

5.6 Restrictions on Shares. Each award made hereunder shall be subject to the requirement that if at any time the Company determines that the listing, registration or qualification of the Shares subject to such award upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the delivery of shares thereunder, such shares shall not be delivered unless such listing, registration, qualification, consent, approval or other action shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company may require that certificates evidencing Shares delivered pursuant to any award made hereunder bear a legend indicating that the sale, transfer or other disposition thereof by the holder is prohibited except in compliance with the Securities Act of 1933, as amended, and the rules and regulations thereunder.

13

5.7 Adjustment. In the event of any equity restructuring (within the meaning of Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation—Stock Compensation) that causes the per Share value of Shares to change after the effectiveness of the Initial Public Offering, such as a stock dividend, stock split, spinoff, rights offering or recapitalization through an extraordinary dividend, the number and class of securities available under this Plan or specified in any section of this Plan, the terms of each outstanding option and SAR (including the number and class of securities subject to each outstanding option or SAR and the purchase price or base price per share), the terms of each outstanding Restricted Stock Award and Restricted Stock Unit Award (including the number and class of securities subject thereto), and the terms of each outstanding Performance Unit Award shall be appropriately adjusted by the Committee, such adjustments to be made in the case of outstanding options and SARs without an increase in the aggregate purchase price or base price and in accordance with Section 409A of the Code. In the event of any other change in corporate capitalization, including a merger, consolidation, reorganization, or partial or complete liquidation of the Company, such equitable adjustments described in the foregoing sentence may be made as determined to be appropriate and equitable by the Committee to prevent dilution or enlargement of rights of participants. In either case, the decision of the Committee regarding any such adjustment shall be final, binding and conclusive.

5.8 Change in Control.

(a) Subject to the terms of the applicable award Agreement, in the event of a Change in Control, the Board (as constituted prior to such Change in Control) may, in its discretion:

14

(b) A “Change in Control” of the Company shall be deemed to have occurred upon the occurrence of any of the following events:

15

In no event shall a Change in Control include the Initial Public Offering or any bona fide primary or secondary public offering following the occurrence of the Initial Public Offering.

5.9 Deferrals. The Committee may determine that the delivery of Shares or the payment of cash, or a combination thereof, upon the exercise or settlement of all or a portion of any award (other than awards of Incentive Stock Options, Nonqualified Options and SARs) made hereunder shall be deferred, or the Committee may, in its sole discretion, approve deferral elections made by holders of awards. Deferrals shall be for such periods and upon such terms as the Committee may determine in its sole discretion, subject to the requirements of Section 409A of the Code.

5.10 No Right of Participation, Employment or Service. Unless otherwise set forth in an employment agreement, no person shall have any right to participate in this Plan. Neither this Plan nor any award made hereunder shall confer upon any person any right to continued employment by or service with the Company, any Subsidiary or any affiliate of the Company or affect in any manner the right of the Company, any Subsidiary or any affiliate of the Company to terminate the employment or service of any person at any time without liability hereunder.

5.11 Rights as Stockholder. No person shall have any right as a stockholder of the Company with respect to any Shares or other equity security of the Company which is subject to an award hereunder unless and until such person becomes a stockholder of record with respect to such Shares or equity security.

5.12 Designation of Beneficiary. A holder of an award may file with the Committee a written designation of one or more persons as such holder’s beneficiary or beneficiaries (both primary and contingent) in the event of the holder’s death or incapacity. To the extent an outstanding option or SAR granted hereunder is exercisable, such beneficiary or beneficiaries shall be entitled to exercise such option or SAR pursuant to procedures prescribed by the Committee.

Each beneficiary designation shall become effective only when filed in writing with the Committee during the holder’s lifetime on a form prescribed by the Committee. The spouse of a married holder domiciled in a community property jurisdiction shall join in any designation of a beneficiary other than such spouse. The filing with the Committee of a new beneficiary designation shall cancel all previously filed beneficiary designations.

If a holder fails to designate a beneficiary, or if all designated beneficiaries of a holder predecease the holder, then each outstanding option and SAR hereunder held by such holder, to the extent exercisable, may be exercised by such holder’s executor, administrator, legal representative or similar person.

16

5.13 Governing Law. This Plan, each award hereunder and the related Agreement, and all determinations made and actions taken pursuant thereto, to the extent not otherwise governed by the Code or the laws of the United States, shall be governed by the laws of the State of Delaware and construed in accordance therewith without giving effect to principles of conflicts of laws.

5.14 Non-U.S. Service Providers. Without amending this Plan, the Committee may grant awards to eligible persons who are foreign nationals on such terms and conditions different from those specified in this Plan as may in the judgment of the Committee be necessary or desirable to foster and promote achievement of the purposes of this Plan and, in furtherance of such purposes the Committee may make such modifications, amendments, procedures, subplans and the like as may be necessary or advisable to comply with provisions of laws in other countries or jurisdictions in which the Company or its Subsidiaries operates or has employees or service providers.

5.15 Awards Subject to Clawback. The awards granted under this Plan and any cash payment or Shares delivered pursuant to an award are subject to forfeiture, recovery by the Company or other action pursuant to the applicable Agreement or any clawback or recoupment policy which the Company may adopt from time to time, including without limitation any such policy which the Company may be required to adopt under the Dodd-Frank Wall Street Reform and Consumer Protection Act and implementing rules and regulations thereunder, or as otherwise required by law.

All other payroll deductions accumulated in a Participant’s Purchase Account and not used to purchase Shares on an Exercise Date shall be distributed to the Participant. During a Participant’s lifetime, a Participant’s Option is exercisable only by him or her. The Company shall satisfy the exercise of all Participants’ Options for the purchase of Shares through (a) the issuance of authorized but unissued Shares, (b) the transfer of treasury Shares, (c) the purchase of Shares on behalf of the applicable Participants on the open market through an independent broker and/or (d) a combination of the foregoing.

9. Issuance of Stock. The Shares purchased by each Participant shall be issued in book entry form and shall be considered to be issued and outstanding to such Participant’s credit as of the end of the last day of each Offering Period.

The Committee may permit Shares purchased under the Plan to participate in a dividend reinvestment plan or program maintained by the Company, and establish a default method for the payment of dividends.

10. Approval by Stockholders. Notwithstanding the above, the Plan is expressly made subject to the approval of the stockholders of the Company within 12 months before or after the date the Plan is adopted by the Board. Such stockholder approval shall be obtained in the manner and to the degree required under applicable federal and state law. If the Plan is not so approved by the stockholders within 12 months before or after the date the Plan is adopted by the Board, this Plan shall not come into effect.

11. Administration.

(a) Powers and Duties of the Committee. The Plan shall be administered by the Committee. Subject to the provisions of the Plan, Section 423 of the Code and the regulations thereunder, the Committee shall have the discretionary authority to determine the time and frequency of granting Options, the terms and conditions of the Options and the number of Shares subject to each Option. The Committee shall also have the discretionary authority to do everything necessary and appropriate to administer the Plan, including, without limitation, interpreting the provisions of the Plan (but any such interpretation shall not be inconsistent with the provisions of Section 423 of the Code).

No member of the Board or the Committee shall be liable for any action, decision, determination or interpretation made in good faith with respect to the Plan or any Option granted hereunder.

(c) Indemnification. Each person who is or shall have been (a) a member of the Board, (b) a member of the Committee, or (c) an officer or employee of the Company to whom authority was delegated in relation to this Plan, shall be indemnified and held harmless by the Company against and from any loss, cost, liability or expense that may be imposed upon or reasonably incurred by him or her 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 taken or failure to act under the Plan and against and from any and all amounts paid by him or her in settlement thereof, with the Company’s approval, or paid by him or her in satisfaction of any judgment in any such claim, action, suit or proceeding against him or her; provided, however, that he or she shall give 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, unless such loss, cost, liability or expense is a result of his or her own willful misconduct or except as expressly provided by statute.

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 certificate of incorporation or bylaws, any contract with the Company, as a matter of law, or otherwise, or of any power that the Company may have to indemnify them or hold them harmless.

12. Withdrawal. A Participant may withdraw from the Plan by properly completing and submitting to the Company a withdrawal form in accordance with the procedures prescribed by the Committee, which must be submitted prior to the date specified by the Committee before the last day of the applicable Offering Period. Upon withdrawal, any payroll deductions credited to the Participant’s Purchase Account prior to the effective date of the Participant’s withdrawal from the Plan will be returned to the Participant. No further payroll deductions for the purchase of Shares will be made during subsequent Offering Periods, unless the Participant properly completes and submits an election form, by the deadline prescribed by the Company. A Participant’s withdrawal from an offering will not have any effect upon his or her eligibility to participate in the Plan or in any similar plan that may hereafter be adopted by the Company.

13. Termination of Employment. On the Termination Date of a Participant for any reason prior to the applicable Exercise Date, whether voluntary or involuntary, and including termination of employment due to retirement, death or as a result of liquidation, dissolution, sale, merger or a similar event affecting the Company or a Participating Subsidiary, the corresponding payroll deductions credited to his or her Purchase Account will be returned to him or her or, in the case of the Participant’s death, to the person or persons entitled thereto under Section 16, and his or her Option will be automatically terminated.

14. Interest. No interest shall accrue on the payroll deductions of a Participant in the Plan.

6

15. Stock.

(a) The stock subject to Options shall be common stock of the Company as traded on the NASDAQ or on such other exchange as the Shares may be listed.

(b) Subject to adjustment upon changes in capitalization of the Company as provided in Section 18 hereof, the maximum aggregate number of Shares which shall be made available under the Plan shall be 2,370,546 Shares. If, on a given Exercise Date, the number of Shares with respect to which Options are to be exercised exceeds the number of Shares then available under the Plan, the Committee shall make a pro rata allocation of the Shares remaining available for purchase in as uniform a manner as shall be practicable and as it shall determine to be equitable.

(c) A Participant shall have no interest or voting right in Shares covered by his or her Option until such Option has been exercised and the Participant has become a holder of record of Shares acquired pursuant to such exercise.

16. Designation of Beneficiary. The Committee may permit Participants to designate beneficiaries to receive any Purchased Shares or payroll deductions, if any, in the Participant’s accounts under the Plan in the event of such Participant’s death. Beneficiary designations shall be made in accordance with procedures prescribed by the Committee. If no properly designated beneficiary survives the Participant, the Purchased Shares and payroll deductions, if any, will be distributed to the Participant’s estate.

17. Assignability of Options. Neither payroll deductions credited to a Participant’s Purchase Account nor any rights with regard to the exercise of an Option or to receive Shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 16 hereof) by the Participant. Any such attempt at assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw from an Offering Period in accordance with Section 12 hereof.

18. Adjustment of Number of Shares Subject to Options.

(a) Adjustment. Subject to any required action by the stockholders of the Company, the maximum number of securities available for purchase under the Plan, as well as the price per security and the number of securities covered by each Option under the Plan which has not yet been exercised shall be appropriately adjusted in the event of any stock split, reverse stock split, stock dividend, combination or reclassification of the common stock of the Company, or any other increase or decrease in the number of Shares effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Board or the Committee, whose determination in that respect shall be final, binding and conclusive. If any such adjustment would result in a fractional security being available under the Plan, such fractional security shall be disregarded. Except as expressly provided herein, 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 or price of Shares subject to an Option. The Options granted pursuant to the Plan shall not be adjusted in a manner that causes the Options to fail to qualify as options issued pursuant to an “employee stock purchase plan” within the meaning of Section 423 of the Code.

7

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Offering Period then in progress will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Board, and the Board may either provide for the purchase of Shares as of the date on which such Offering Period terminates or return to each Participant the payroll deductions credited to such Participant’s Purchase Account.

(c) Merger or Asset Sale. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each outstanding Option shall be assumed or an equivalent option substituted by the successor corporation or a parent or subsidiary of the successor corporation, unless the Board determines, in the exercise of its sole discretion, that in lieu of such assumption or substitution to either terminate all outstanding Options and return to each Participant the payroll deductions credited to such Participant’s Purchase Account or to provide for the Offering Period in progress to end on a date prior to the consummation of such sale or merger.

19. Amendments or Termination of the Plan.

(a) The Board or the Committee may at any time and for any reason amend, modify, suspend, discontinue or terminate the Plan without notice; provided that no Participant’s existing rights in respect of existing Options are adversely affected thereby. To the extent necessary to comply with Section 423 of the Code (or any other applicable law, regulation or stock exchange rule), the Company shall obtain stockholder approval in such a manner and to such a degree as required.

(b) Without stockholder consent and without regard to whether any Participant rights may be considered to have been “adversely affected,” the Board or the Committee shall be entitled to change the Purchase Price, Offering Periods, limit or increase the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll withholding in an amount less than or greater than the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Shares for each Participant properly correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as the Board or the Committee determines in its sole discretion advisable which are consistent with the Plan; provided, however, that changes to (i) the Purchase Price, (ii) the Offering Period, (iii) the maximum percentage of Compensation that may be deducted pursuant to Section 6(a) or (iv) the maximum number of Shares that may be purchased in an Offering Period, shall not be effective until communicated to Participants in a reasonable manner, with the determination of such reasonable manner in the sole discretion of the Board or the Committee.

8

20. No Other Obligations. The receipt of an Option pursuant to the Plan shall impose no obligation upon the Participant to purchase any Shares covered by such Option. Nor shall the granting of an Option pursuant to the Plan constitute an agreement or an understanding, express or implied, on the part of the Company to employ the Participant for any specified period.

21. Notices and Communication. Any notice or other form of communication which the Company or a Participant may be required or permitted to give to the other shall be provided through such means as designated by the Committee, including but not limited to any paper or electronic method.

22. Condition Upon Issuance of Shares.

(a) Shares shall not be issued with respect to an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation, the 1933 Act and the 1934 Act and the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance.

(b) As a condition to the exercise of an Option, the Company may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned applicable provisions of law.
