     3.3 Delegation to Committee.

          (i) General.

If administration is delegated to a Committee, the Committee also may exercise, in connection with the administration of the Plan, any of the powers and authority granted to the Board under the Plan, and the Committee may delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board shall thereafter be to the Committee or subcommittee, as applicable), subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board.

To the extent any provision of this Plan or action by the Board fails to so comply, it shall be deemed null and void, to the extent permitted by law and deemed advisable by the Board. Notwithstanding the above, it shall be the responsibility of such persons, not of the Company or the Board, to comply with the requirements of Section 16 of the Exchange Act; and neither the Company nor the Board shall be liable if this Plan or any transaction under this Plan fails to comply with the applicable conditions of Rule 16b-3 or any successor rule thereto, or if any person incurs any liability under Section 16 of the Exchange Act.

added to the Share Reserve that are (a) tendered in payment of an Option, (b) withheld by the Company to satisfy any tax withholding obligation, or (c) repurchased by the Company with Option proceeds, and provided, further, that shares of Common Stock covered by a Stock Appreciation Right, to the extent that it is exercised and settled in shares of Common Stock, and whether or not shares of Common Stock are actually issued to the Participant upon exercise of the Stock Appreciation Right, shall be considered issued or transferred pursuant to the Plan.

All Options shall be separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate certificate or certificates will be issued for shares of Common Stock purchased upon exercise of each type of Option. The provisions of separate Options need not be identical, but each Option shall include (through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions:

     6.1 Term.

Subject to the provisions of Section 5.2 of the Plan regarding Ten Percent Shareholders, the exercise price of each Incentive Stock Option shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, an Incentive Stock Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner satisfying the provisions of Section 424(a) of the Code.

     6.3 Exercise Price of a Nonstatutory Stock Option. The exercise price of each Nonstatutory Stock Option shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted.

     6.4 Consideration. The purchase price of Common Stock acquired pursuant to an Option shall be paid, to the extent permitted by applicable statutes and regulations, either (i) in cash or by check at the time the Option is exercised or (ii) at the discretion of the Board at the time of the grant of the Option (or subsequently in the case of a Nonstatutory Stock Option): (1) by delivery to the Company of other Common Stock, (2) pursuant to a “same day sale” program to the extent permitted by law, (3) reduction of the Company’s liability to the Optionholder, (4) by any other form of consideration permitted by law, but in no event shall a promissory note or other form of deferred payment constitute a permissible form of consideration for an Option

granted under the Plan, or (5) by some combination of the foregoing. In the absence of a provision to the contrary in the individual Optionholder’s Option Agreement, payment for Common Stock pursuant to an Option may only be made in the form of cash, check, or pursuant to a “same day sale” program.

     Unless otherwise specifically provided in the Option, the purchase price of Common Stock acquired pursuant to an Option that is paid by delivery to the Company of other Common Stock acquired, directly or indirectly from the Company, shall be paid only by shares of the Common Stock of the Company that have been held for more than six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes).

     6.5 Transferability of an Incentive Stock Option. An Incentive Stock Option shall not be transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the foregoing, the Optionholder may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option.

     6.6 Transferability of a Nonstatutory Stock Option. A Nonstatutory Stock Option shall be transferable to the extent provided in the Option Agreement. If the Nonstatutory Stock Option does not provide for transferability, then the Nonstatutory Stock Option shall not be transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the foregoing, the Optionholder may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option.

     6.7 Vesting Generally. Options granted under the Plan shall be exercisable at such time and upon such terms and conditions as may be determined by the Board.

If vesting is based on the achievement of performance criteria, such Options shall not fully vest in less than one (1) year. The provisions of this Section 6.7 are subject to any Option provisions governing the minimum number of shares of Common Stock as to which an Option may be exercised. Notwithstanding the foregoing provisions of this Section 6.7, Options granted in recognition of a Participant’s long-term Continuous Service may vest fully in periods shorter than those described above or may be fully vested upon grant.

     6.8 Termination of Continuous Service. In the event an Optionholder’s Continuous Service terminates (other than upon the Optionholder’s death or Disability), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination) but only within such period of time as is specified in the Option Agreement (and in no event later than the expiration of the term of such Option as set forth in the Option Agreement). If, after termination, the Optionholder does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate. In the absence of a provision to the contrary in the individual Optionholder’s Option Agreement, the

Option shall remain exercisable for three (3) months following the termination of the Optionholder’s Continuous Service.

     6.9 Extension of Termination Date. An Optionholder’s Option Agreement may also provide that if the exercise of the Option following the termination of the Optionholder’s Continuous Service (other than upon the Optionholder’s death or Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act or other applicable securities law, then the Option shall terminate on the earlier of (i) the expiration of the term of the Option set forth in the Option Agreement or (ii) the expiration of a period of three (3) months after the termination of the Optionholder’s Continuous Service during which the exercise of the Option would not be in violation of such registration requirements or other applicable securities law. The provisions of this Section 6.9 notwithstanding, in the event that a sale of the shares of Common Stock received upon exercise of his or her Option would subject the Optionholder to liability under Section 16(b) of the Exchange Act, then the Option will terminate on the earlier of (1) the fifteenth (15^th) day after the last date upon which such sale would result in liability, or (2) two hundred ten (210) days following the date of termination of the Optionholder’s employment or other service to the Company (and in no event later than the expiration of the term of the Option).

     6.10 Disability of Optionholder. In the event that an Optionholder’s Continuous Service terminates as a result of the Optionholder’s Disability, the Optionholder may exercise his or her Option to the extent that the Optionholder was entitled to exercise such Option as of the date of termination, but only within such period of time as is specified in the Option Agreement (and in no event later than the expiration of the term of such Option as set forth in the Option Agreement). If, after termination, the Optionholder does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate. In the absence of a provision to the contrary in the individual Optionholder’s Option Agreement, the Option shall remain exercisable for twelve (12) months following such termination.

     6.11 Death of Optionholder. In the event (i) an Optionholder’s Continuous Service terminates as a result of the Optionholder’s death or (ii) the Optionholder dies within the period (if any) specified in the Option Agreement after the termination of the Optionholder’s Continuous Service for a reason other than death, then the Option may be exercised (to the extent the Optionholder was entitled to exercise such Option as of the date of death) by the Optionholder’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the Option upon the Optionholder’s death pursuant to Section 6.5 or 6.6 of the Plan, but only within such period of time as is specified in the Option Agreement (and in no event later than the expiration of the term of such Option as set forth in the Option Agreement). If, after death, the Option is not exercised within the time specified in the Option Agreement, the Option shall terminate. In the absence of a provision to the contrary in the individual Optionholder’s Option Agreement, the Option shall remain exercisable for twelve (12) months following the Optionholder’s death.

     6.12 Early Exercise Generally Not Permitted. The Company’s general policy is not to allow the Optionholder to exercise the Option as to any part or all of the shares of Common Stock subject to the Option prior to the vesting of the Option. If, however, an Option Agreement does permit such early exercise, any unvested shares of Common Stock so purchased may be

subject to a repurchase option in favor of the Company or to any other restriction the Board determines to be appropriate.

VII.      NON-DISCRETIONARY STOCK AWARDS FOR ELIGIBLE DIRECTORS

     In addition to any other Stock Awards that Eligible Directors may be granted on a discretionary basis under the Plan, each Eligible Director of the Company shall be automatically granted without the necessity of action by the Board, the following Stock Awards.

     7.1 Initial Grant. On the date that a Director commences service on the Board and satisfies the definition of an Eligible Director, an initial grant of restricted stock in the form of a Restricted Stock Bonus award or an award of Restricted Stock Units shall automatically be made to that Eligible Director (the “Initial Grant”). Unless expressly provided in this Article VII, such Initial Grant shall be subject to the applicable provisions of Section 8.1 or Section 8.5, as the case may be. In the absence of an affirmative decision by the Board to the contrary, the Initial Grant shall be in the form of a Restricted Stock Bonus award. The number of shares subject to this Initial Grant shall be Seven Thousand (7,000) shares; provided, however, that prior to the date of grant the Board may, in its sole discretion, provide that a different number of shares shall be subject to this Initial Grant. The other terms governing this Initial Grant shall be as determined by the Board in its sole discretion.. If at the time a Director commences service on the Board, the Director does not satisfy the definition of an Eligible Director, such Director shall not be entitled to an Initial Grant at any time, even if such Director subsequently becomes an Eligible Director.

     7.2 Annual Grant. An annual grant of restricted stock in the form of a Restricted Stock Bonus award or an award of Restricted Stock Units (the “Annual Grant”) shall automatically be made to each Director who (1) is re-elected to the Board and (2) is an Eligible Director on the relevant grant date. Unless expressly provided in this Article VII, such Annual Grant shall be subject to the applicable provisions of Section 8.1 or Section 8.5, as the case may be. In the absence of an affirmative decision by the Board to the contrary, the Annual Grant shall be in the form of a Restricted Stock Bonus award. The number of shares subject to this Annual Grant shall be Five Thousand (5,000) shares. The other terms governing this Annual Grant shall be as determined by the Board in its sole discretion. The date of grant of an Annual Grant is the date of the first meeting of the Board following the annual meeting of the Company’s shareholders (even if that Board meeting is held on the same day as the annual meeting of the shareholders).

     7.3 Vesting. Initial Grants and Annual Grants granted pursuant to this Article shall be subject to a share reacquisition right in favor of the Company. Such grants shall vest as to one fourth (1/4) of the total award annually, such that the award is fully vested after four (4) years of Continuous Service. In the event a Director’s Continuous Service terminates, the Company shall automatically reacquire without cost any shares of Common Stock held by the Director that have not vested as of the date of such termination and any unvested Restricted Stock Units shall automatically expire as of the date of such termination.

VIII.       PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS

     8.1 Restricted Stock Bonus Awards. Each Restricted Stock Bonus agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. Restricted Stock Bonuses shall be paid by the Company in shares of the Common Stock of the Company. The terms and conditions of Restricted Stock Bonus agreements may change from time to time, and the terms and conditions of separate Restricted Stock Bonus agreements need not be identical, but each Restricted Stock Bonus agreement shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:

          (i) Consideration. A Restricted Stock Bonus may be awarded in consideration for past services actually rendered to the Company or an Affiliate for its benefit; provided, however, that in the case of a Restricted Stock Bonus to be made to a new Employee, Director, or Consultant who has not performed prior services for the Company, the Restricted Stock Bonus will not be awarded until the Board determines that such person has rendered services to the Company for a sufficient period of time to ensure proper issuance of the shares in compliance with the California Corporations Code.

          (ii) Vesting. Vesting shall generally be based on the Participant’s Continuous Service. Shares of Common Stock awarded under the Restricted Stock Bonus agreement shall be subject to a share reacquisition right in favor of the Company in accordance with a vesting schedule to be determined by the Board. Absent a provision to the contrary in the Participant’s Restricted Stock Bonus agreement, so long as the Participant remains in Continuous Service with the Company, a Restricted Stock Bonus granted to the Participant shall vest as to one fourth (1/4) of the total Restricted Stock Bonus award on each annual anniversary of the grant date, such that the Restricted Stock Bonus is fully vested after four (4) years of Continuous Service from the grant date. If vesting is based on the Participant’s Continuous Service, such Restricted Stock Bonus shall not fully vest in less than three (3) years. If vesting is based on the achievement of performance criteria, such Restricted Stock Bonus shall not fully vest in less than one (1) year. Notwithstanding the foregoing provisions of this Section 8.1(ii), a Restricted Stock Bonus granted in recognition of a Participant’s long-term Continuous Service may vest fully in periods shorter than those described above or may be fully vested upon grant (“Accelerated Vesting Restricted Stock Bonuses”), subject to provisions of the last sentence of Section 4.1.

          (iii) Termination of Participant’s Continuous Service. In the event a Participant’s Continuous Service terminates, the Company shall automatically reacquire without cost any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination under the terms of the Restricted Stock Bonus agreement.

          (iv) Transferability. Rights to acquire shares of Common Stock under the Restricted Stock Bonus agreement shall be transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Bonus agreement, as the Board shall determine in its discretion, so long as Common Stock awarded under the Restricted Stock Bonus agreement remains subject to the terms of the Restricted Stock Bonus agreement.

     8.2 Restricted Stock Purchase Awards. Each Restricted Stock Purchase Right agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The terms and conditions of the Restricted Stock Purchase Right agreements may change from time to time, and the terms and conditions of separate Restricted Stock Purchase Right agreements need not be identical, but each Restricted Stock Purchase Right agreement shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:

          (i) Purchase Price. The purchase price under each Restricted Stock Purchase Right agreement shall be such amount as the Board shall determine and designate in such Restricted Stock Purchase Right agreement. The purchase price shall not be less than one hundred percent (100%) of the Common Stock’s Fair Market Value on the date such award is made or at the time the purchase is consummated.

          (ii) Consideration. The purchase price of Common Stock acquired pursuant to the Restricted Stock Purchase Right agreement shall be paid either: (A) in cash or by check at the time of purchase; or (B) at the discretion of the Board, according to a deferred payment or other similar arrangement with the Participant to the extent permitted by law.

          (iii) Vesting. The Board shall determine the criteria under which shares of Common Stock under the Restricted Stock Purchase Right agreement may vest; the criteria may or may not include performance criteria or Continuous Service. Shares of Common Stock acquired under the Restricted Stock Purchase Right agreement may, but need not, be subject to a share repurchase option in favor of the Company in accordance with a vesting schedule to be determined by the Board.

          (iv) Termination of Participant’s Continuous Service. In the event a Participant’s Continuous Service terminates, the Company may repurchase any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination under the terms of the Restricted Stock Purchase Right agreement.

          (v) Transferability. Rights to acquire shares of Common Stock under the Restricted Stock Purchase Right agreement shall be transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Purchase Right agreement, as the Board shall determine in its discretion, so long as Common Stock awarded under the Restricted Stock Purchase Right agreement remains subject to the terms of the Restricted Stock Purchase Right agreement.

     8.3 Stock Appreciation Rights. Two types of Stock Appreciation Rights (“SARs”) shall be authorized for issuance under the Plan: (1) stand-alone SARs and (2) stapled SARs.

          (i) Stand-Alone SARs. The following terms and conditions shall govern the grant and redeemability of stand-alone SARs:

     (A) The stand-alone SAR shall cover a specified number of underlying shares of Common Stock and shall be redeemable upon such terms and conditions as the Board may establish. Upon redemption of the stand-alone SAR, the holder shall be entitled to receive a distribution from the Company in an amount equal to the excess of (i) the aggregate Fair Market

Value (on the redemption date) of the shares of Common Stock underlying the redeemed right over (ii) the aggregate base price in effect for those shares.

     (B) The number of shares of Common Stock underlying each stand-alone SAR and the base price in effect for those shares shall be determined by the Board in its sole discretion at the time the stand-alone SAR is granted. In no event, however, may the base price per share be less than one hundred percent (100%) of the Fair Market Value per underlying share of Common Stock on the grant date.

     (C) The distribution with respect to any redeemed stand-alone SAR may be made in shares of Common Stock valued at Fair Market Value on the redemption date, in cash, or partly in shares and partly in cash, as the Board shall in its sole discretion deem appropriate.

          (ii) Stapled SARs. The following terms and conditions shall govern the grant and redemption of stapled SARs:

     (A) Stapled SARs may only be granted concurrently with an Option to acquire the same number of shares of Common Stock as the number of such shares underlying the stapled SARs.

     (B) Stapled SARs shall be redeemable upon such terms and conditions as the Board may establish and shall grant a holder the right to elect among (i) the exercise of the concurrently granted Option for shares of Common Stock, whereupon the number of shares of Common Stock subject to the stapled SARs shall be reduced by an equivalent number, (ii) the redemption of such stapled SARs in exchange for a distribution from the Company in an amount equal to the excess of the Fair Market Value (on the redemption date) of the number of vested shares which the holder redeems over the aggregate base price for such vested shares, whereupon the number of shares of Common Stock subject to the concurrently granted Option shall be reduced by any equivalent number, or (iii) a combination of (i) and (ii).

     (C) The distribution to which the holder of stapled SARs shall become entitled under this Section 8 upon the redemption of stapled SARs as described in Section 8.3(ii)(B) above may be made in shares of Common Stock valued at Fair Market Value on the redemption date, in cash, or partly in shares and partly in cash, as the Board shall in its sole discretion deem appropriate.

     8.4 Phantom Stock Units. The following terms and conditions shall govern the grant and redeemability of Phantom Stock Units:

          (i) Phantom Stock Unit awards shall be redeemable by the Participant upon such terms and conditions as the Board may establish. The value of a single Phantom Stock Unit shall be equal to the Fair Market Value of a share of Common Stock, unless the Board otherwise provides in the terms of the Stock Award Agreement.

          (ii) The distribution with respect to any exercised Phantom Stock Unit award may be made in shares of Common Stock valued at Fair Market Value on the redemption date, in cash, or partly in shares and partly in cash, as the Board shall in its sole discretion deem appropriate.

     8.5 Restricted Stock Units. The following terms and conditions shall govern the grant and redeemability of Restricted Stock Units:

     A Restricted Stock Unit is the right to receive the value of one (1) share of the Company’s Common Stock at the time the Restricted Stock Unit vests. To the extent permitted by the Board in the terms of his or her Restricted Stock Unit agreement, a Participant may elect to defer receipt of the value of the shares of Common Stock otherwise deliverable upon the vesting of an award of Restricted Stock Units, so long as such deferral election complies with applicable law, including to the extent applicable, the Employee Retirement Income Security Act of 1974, as amended (“ERISA”). An election to defer such delivery shall be irrevocable and shall be made in writing on a form acceptable to the Company. The election form shall be filed prior to the vesting date of such Restricted Stock Units in a manner determined by the Board. When the Participant vests in such Restricted Stock Units, the Participant will be credited with a number of Restricted Stock Units equal to the number of shares of Common Stock for which delivery is deferred. Restricted Stock Units may be paid by the Company by delivery of shares of Common Stock, in cash, or a combination thereof, as the Board shall in its sole discretion deem appropriate, in accordance with the timing and manner of payment elected by the Participant on his or her election form, or if no deferral election is made, as soon as administratively practicable following the vesting of the Restricted Stock Unit.

     Each Restricted Stock Unit agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The terms and conditions of Restricted Stock Unit agreements may change from time to time, and the terms and conditions of separate Restricted Stock Unit agreements need not be identical, but each Restricted Stock Unit agreement shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:

          (i) Consideration. A Restricted Stock Unit may be awarded in consideration for past services actually rendered to the Company or an Affiliate for its benefit. The Board shall have the discretion to provide that the Participant pay for such Restricted Stock Unit with cash or other consideration permissible by law.

          (ii) Vesting. Vesting shall generally be based on the Participant’s Continuous Service. If vesting is based on the Participant’s Continuous Service, such Restricted Stock Unit award shall not fully vest in less than three (3) years. If vesting is based on the achievement of performance criteria, such Restricted Stock Unit award shall not fully vest in less than one (1) year. Notwithstanding the foregoing provisions of this Section 8.5(ii), a Restricted Stock Unit granted in recognition of a Participant’s long-term Continuous Service may vest fully in periods shorter than those described above (“Accelerated Vesting Restricted Stock Units”), subject to provisions of the last sentence of Section 4.1.

          (iii) Termination of Participant’s Continuous Service. The unvested portion of the Restricted Stock Unit award shall expire immediately upon the termination of Participant’s Continuous Service.

          (iv) Transferability. Rights to acquire the value of shares of Common Stock under the Restricted Stock Unit agreement shall be transferable by the Participant only upon such

terms and conditions as are set forth in the Restricted Stock Unit agreement, as the Board shall determine in its discretion, so long as any Common Stock awarded under the Restricted Stock Unit agreement remains subject to the terms of the Restricted Stock Unit agreement.

     8.6 Performance Share Bonus Awards. Each Performance Share Bonus agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. Performance Share Bonuses shall be paid by the Company in shares of the Common Stock of the Company. The terms and conditions of Performance Share Bonus agreements may change from time to time, and the terms and conditions of separate Performance Share Bonus agreements need not be identical, but each Performance Share Bonus agreement shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:

          (i) Consideration. A Performance Share Bonus may be awarded in consideration for past services actually rendered to the Company or an Affiliate for its benefit. In the event that a Performance Share Bonus is granted to a new Employee, Director, or Consultant who has not performed prior services for the Company, the Performance Share Bonus will not be awarded until the Board determines that such person has rendered services to the Company for a sufficient period of time to ensure proper issuance of the shares in compliance with the California Corporations Code.

          (ii) Vesting. Vesting shall be based on the achievement of certain performance criteria, whether financial, transactional or otherwise, as determined by the Board. A Performance Share Bonus shall not fully vest in less than one (1) year. Vesting shall be subject to the Performance Share Bonus agreement. Upon failure to meet performance criteria, shares of Common Stock awarded under the Performance Share Bonus agreement shall be subject to a share reacquisition right in favor of the Company in accordance with a vesting schedule to be determined by the Board.

          (iii) Termination of Participant’s Continuous Service. In the event a Participant’s Continuous Service terminates, the Company shall reacquire any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination under the terms of the Performance Share Bonus agreement.

          (iv) Transferability. Rights to acquire shares of Common Stock under the Performance Share Bonus agreement shall be transferable by the Participant only upon such terms and conditions as are set forth in the Performance Share Bonus agreement, as the Board shall determine in its discretion, so long as Common Stock awarded under the Performance Share Bonus agreement remains subject to the terms of the Performance Share Bonus agreement.

     8.7 Performance Share Units. The following terms and conditions shall govern the grant and redeemability of Performance Share Units:

     A Performance Share Unit is the right to receive the value of one (1) share of the Company’s Common Stock at the time the Performance Share Unit vests. To the extent permitted by the Board in the terms of his or her Performance Share Unit agreement, a Participant may elect to defer receipt of the value of shares of Common Stock otherwise

deliverable upon the vesting of an award of performance shares. An election to defer such delivery shall be irrevocable and shall be made in writing on a form acceptable to the Company. The election form shall be filed prior to the vesting date of such performance shares in a manner determined by the Board. When the Participant vests in such performance shares, the Participant will be credited with a number of Performance Share Units equal to the number of shares of Common Stock for which delivery is deferred. Performance Share Units may be paid by the Company by delivery of shares of Common Stock, in cash, or a combination thereof, as the Board shall in its sole discretion deem appropriate, in accordance with the timing and manner of payment elected by the Participant on his or her election form, or if no deferral election is made, as soon as administratively practicable following the vesting of the Performance Share Unit.

     Each Performance Share Unit agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The terms and conditions of Performance Share Unit agreements may change from time to time, and the terms and conditions of separate Performance Share Unit agreements need not be identical, but each Performance Share Unit agreement shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:

          (i) Consideration. A Performance Share Unit may be awarded in consideration for past services actually rendered to the Company or an Affiliate for its benefit. The Board shall have the discretion to provide that the Participant pay for such Performance Share Unit with cash or other consideration permissible by law.

          (ii) Vesting. Vesting shall be based on the achievement of certain performance criteria, whether financial, transactional or otherwise, as determined by the Board. Vesting shall be subject to the Performance Share Unit agreement. The terms of the Performance Share Unit agreement notwithstanding, a Performance Share Unit may not fully vest in less than one (1) year.

          (iii) Termination of Participant’ Continuous Service. The unvested portion of any Performance Share Unit shall expire immediately upon the termination of Participant’s Continuous Service.

          (iv) Transferability. Rights to acquire the value of shares of Common Stock under the Performance Share Unit agreement shall be transferable by the Participant only upon such terms and conditions as are set forth in the Performance Share Unit agreement, as the Board shall determine in its discretion, so long as Common Stock awarded under the Performance Share Unit agreement remains subject to the terms of the Performance Share Unit agreement.

IX.      COVENANTS OF THE COMPANY

     9.1 Availability of Shares. During the term of the Stock Awards, the Company shall keep available at all times the number of shares of Common Stock required to satisfy such Stock Awards.

     9.2 Securities Law Compliance. The Company shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise,

redemption or satisfaction of the Stock Awards; provided, however, that this undertaking shall not require the Company to register under the Securities Act the Plan or any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common Stock related to such Stock Awards unless and until such authority is obtained.

X.      USE OF PROCEEDS FROM STOCK

     Proceeds from the sale of Common Stock pursuant to Stock Awards shall constitute general funds of the Company.

XI.      CANCELLATION AND RE-GRANT OF OPTIONS

     11.1 The Board shall have the authority to effect, at any time and from time to time, (i) the repricing of any outstanding Options under the Plan and/or (ii) with the consent of the affected Optionholders, the cancellation of any outstanding Options under the Plan and the grant in substitution therefor of new Options under the Plan covering the same or different number of shares of Common Stock, but having an exercise price per share not less than one hundred percent (100%) of the Fair Market Value or, in the case of a Ten Percent Shareholder (as described in Section 5.2 of the Plan), not less than one hundred ten percent (110%) of the Fair Market Value) per share of Common Stock on the new grant date. Notwithstanding the foregoing, the Board may grant an Option with an exercise price lower than that set forth above if such Option is granted as part of a transaction to which Section 424(a) of the Code applies. Notwithstanding anything to the contrary in this Section 11.1, prior to the implementation of any such repricing or cancellation of one or more outstanding Options, the Board shall obtain the approval of the shareholders of the Company to the extent required by any New York Stock Exchange, Nasdaq or other securities exchange listing requirements, or applicable law.

     11.2 Shares subject to an Option cancelled under this Section 11 shall continue to be counted against the maximum award of Options permitted to be granted pursuant to Section 5.3 of the Plan. The repricing of an Option under this Section 11, resulting in a reduction of the exercise price, shall be deemed to be a cancellation of the original Option and the grant of a substitute Option; in the event of such repricing, both the original and the substituted Options shall be counted against the maximum awards of Options permitted to be granted pursuant to Section 5.3 of the Plan. The provisions of this Section 11.2 shall be applicable only to the extent required by Section 162(m) of the Code.

XII.      MISCELLANEOUS

     12.1 Acceleration of Exercisability and Vesting. The Board (or Committee, if so authorized by the Board) shall have the power to accelerate exercisability and/or vesting of any Stock Award granted pursuant to the Plan upon a Change of Control or upon the death, Disability or termination of Continuous Service of the Participant. In furtherance of such power, the Board or Committee may accelerate the time at which a Stock Award may first be exercised

or the time during which a Stock Award or any part thereof will vest in accordance with the Plan, notwithstanding any provisions in the Stock Award Agreement to the contrary.

     12.2 Shareholder Rights. No Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to a Stock Award except to the extent that the Company has issued the shares of Common Stock relating to such Stock Award.

     12.3 No Employment or Other Service Rights. Nothing in the Plan or any instrument executed or Stock Award granted pursuant thereto shall confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Stock Award was granted or shall affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the Bylaws of the Company, and any applicable provisions of the corporate law of the state or other jurisdiction in which the Company is domiciled, as the case may be.

     12.4 Incentive Stock Option $100,000 Limitation. To the extent that the aggregate Fair Market Value (determined at the time of grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and its Affiliates) exceeds One Hundred Thousand dollars ($100,000), or such other limit as may be set by law, the Options or portions thereof which exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options.

     12.5 Investment Assurances. The Company may require a Participant, as a condition of exercising or redeeming a Stock Award or acquiring Common Stock under any Stock Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of acquiring the Common Stock; (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Stock Award for the Participant’s own account and not with any present intention of selling or otherwise distributing the Common Stock; and (iii) to give such other written assurances as the Company may determine are reasonable in order to comply with applicable law. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (1) the issuance of the shares of Common Stock under the Stock Award has been registered under a then currently effective registration statement under the Securities Act or (2) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws, and in either case otherwise complies with applicable law. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable laws, including, but not limited to, legends restricting the transfer of the Common Stock.

     12.6 Withholding Obligations. To the extent provided by the terms of a Stock Award Agreement, the Participant may satisfy any federal, state, local, or foreign tax withholding obligation relating to the exercise or redemption of a Stock Award or the acquisition, vesting, distribution, or transfer of Common Stock under a Stock Award by any of the following means (in addition to the Company’s right to withhold from any compensation or other amounts payable to the Participant by the Company) or by a combination of such means: (i) tendering a cash payment; (ii) authorizing the Company to withhold shares of Common Stock from the shares of Common Stock otherwise issuable to the Participant, provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law; or (iii) delivering to the Company owned and unnumbered shares of Common Stock.

     12.7 Section 409A. Notwithstanding anything in the Plan to the contrary, it is the intent of the Company that all Stock Awards granted under this Plan (including, but not limited to, Restricted Stock Units, Phantom Stock Units, and Performance Share Units) shall not cause an imposition of the additional taxes provided for in Section 409A(a)(1)(B) of the Code; furthermore, it is the intent of the Company that the Plan shall be administered so that the additional taxes provided for in Section 409A(a)(1)(B) of the Code are not imposed.

XIII.      ADJUSTMENTS UPON CHANGES IN STOCK

     13.1 Capitalization Adjustments. If any change is made in the Common Stock subject to the Plan, or subject to any Stock Award, without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, spinoff, dividend in property other than cash, stock split, liquidating dividend, extraordinary dividends or distributions, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company), the Plan may be appropriately adjusted in the class(es) and maximum number of securities subject to the Plan pursuant to Section 4.1 above, the maximum number of securities subject to award to any person pursuant to Section 5.3 above, and the number of securities subject to Initial Grants and Annual Grants to Eligible Directors under Article VII of the Plan, and the outstanding Stock Awards may be appropriately adjusted in the class(es) and number of securities or other property and price per share of the securities or other property subject to such outstanding Stock Awards. The Board may make such adjustments in its sole discretion, and its determination shall be final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a transaction “without receipt of consideration” by the Company.)

     13.2 Adjustments Upon a Change of Control.

          (i) In the event of a Change of Control as defined in Section 2.4(i) through 2.4(iv), such as an asset sale, merger, or change in Board composition, then the Board or the board of directors of any surviving entity or acquiring entity may provide or require that the surviving or acquiring entity shall: (1) assume or continue all or any part of the Stock Awards outstanding under the Plan or (2) substitute substantially equivalent stock awards (including an award to acquire substantially the same consideration paid to the shareholders in the transaction by which the Change of Control occurs) for those outstanding under the Plan.

However, except as provided in Section 13 of the Plan relating to adjustments upon changes in Common Stock, no amendment shall be effective unless approved by the shareholders of the Company to the extent shareholder approval is necessary to satisfy the requirements of Section 422 of the Code, any New York Stock Exchange, Nasdaq or other securities exchange listing requirements, or other applicable law or regulation.

     14.2 Shareholder Approval. The Board may, in its sole discretion, submit any other amendment to the Plan for shareholder approval, including, but not limited to, amendments to the Plan intended to satisfy the requirements of Section 162(m) of the Code and the regulations thereunder regarding the exclusion of performance-based compensation from the limit on corporate deductibility of compensation paid to certain executive officers.
