6

Notwithstanding the foregoing, the following Common Shares shall not again become available for issuance under this Article 3.3:  (i) Common Shares subject to an Award not delivered to a Participant because the Award is exercised through a reduction of shares subject to the Award (i.e., “net exercised”), (ii) if a SAR is settled in Common Shares, the number of shares subject to the SAR that are not delivered to the Participant upon such settlement, (iii) Common Shares subject to an Award not delivered to a Participant because such Common Shares are withheld to satisfy tax withholding obligations related to the Award or are applied to pay the Exercise Price of an Option or SAR; (iv) Common Shares tendered by a Participant (either through actual delivery or attestation) to pay the Exercise Price of an Option or SAR; or (v) Common Shares reacquired by the Company on the open market or otherwise using cash proceeds from the exercise of an Option.

(b)                                  The maximum aggregate number of Common Shares subject to Restricted Share awards and Stock Units that may be granted under this Plan during any fiscal year to any one Participant shall not exceed 2,000,000, except that the Company may grant to a new Employee in the fiscal year in which his or her Service as an Employee first commences Restricted Shares and/or Stock Units that cover (in the aggregate) up to an additional 1,000,000 Common Shares;

ARTICLE 5.   OPTIONS .

5.1                                Stock Option Agreement .  Each grant of an Option under the Plan shall be evidenced by a Stock Option Agreement between the Optionee and the Company.  Such Option shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan.  The Stock Option Agreement shall specify whether the Option is intended to be an ISO or an NSO.  The provisions of the various Stock Option Agreements entered into under the Plan need not be identical.

5.2                                Number of Shares .  Each Stock Option Agreement shall specify the number of Common Shares subject to the Option, which number shall adjust in accordance with Article 9.

5.3                                Exercise Price.  Each Stock Option Agreement shall specify the Exercise Price, which shall be such price as is determined by the Administrator in its discretion; provided however , that unless an Option is intended to comply with Code Section 409A (and not, for the avoidance of doubt, be exempt from Code Section 409A) the Exercise Price of any Option granted to a Participant subject to taxation in the United States shall be not be less than 100% of the Fair Market Value of a Common Share on the date of grant; provided further that the preceding clause shall not apply to an Option that is a Substitute Award granted in a manner that would satisfy the requirements of Code Section 409A and, if applicable, Code Section 424(a).

5.4                                Exercisability and Term .  Each Stock Option Agreement shall specify the date or event when all or any installment of the Option is to become vested and/or exercisable; provided that with respect to 95% of the shares available for issuance under the Plan on April 4, 2019, the Option shall not become exercisable prior to the Optionee completing at least one year of Service following the grant of such Option. Notwithstanding the foregoing,  a Stock Option Agreement may provide for accelerated exercisability in the event of the Optionee’s death or disability.  The Stock Option Agreement shall also specify the term of the Option; provided that, except to the extent necessary to comply with applicable foreign law, the term of an Option shall in no event exceed 7 years from the date of grant.

5.5                                Death of Optionee .  After an Optionee’s death, any vested and exercisable Options held by such Optionee may be exercised by his or her beneficiary or beneficiaries.  Each Optionee may designate one or more beneficiaries for this purpose by filing the prescribed form with the Company.  A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Optionee’s death.  If no beneficiary was designated or if no designated beneficiary survives the Optionee, then any vested and exercisable Options held by the Optionee may be exercised by his or her estate.

5.6                                Modification or Assumption of Options .  Within the limitations of the Plan, the Administrator may modify, extend or assume outstanding options or may accept the cancellation of outstanding options (whether granted by the Company or by another issuer) in return for the grant of new Options for the same or a different number of shares and at the same or a different exercise price or in return for the grant of a different type of Award.  The foregoing notwithstanding, no modification of an Option shall, without the consent of the Optionee, impair his or her rights or obligations under such Option. Notwithstanding anything in this Plan to the contrary, and except for the adjustment provided in Article 9, neither the Committee nor any other person may (a) decrease the exercise price of any outstanding Option after the date of grant, (b) cancel or allow an Optionee to surrender an outstanding Option to the Company in exchange for cash or as consideration for the grant of a new Option with a lower exercise price or the grant of another Award the effect of which is to reduce the exercise price of any outstanding Option, or (c) take any other action with respect to an Option that would be treated as a repricing under the rules and regulations of the Nasdaq Stock Market (or such other principal U.S. national securities exchange on which the Common Shares are traded).

5.7                                Buyout Provisions .  Except to the extent prohibited by Article 5.6, the Administrator may at any time (a) offer to buy out for a payment in cash or cash equivalents an Option previously granted or (b) authorize an Optionee to elect to cash out an Option previously granted, in either case at such time and based upon such terms and conditions as the Administrator shall establish.

(a)                                  Subject to any conditions or limitations established by the Administrator, by surrendering, or attesting to the ownership of, Common Shares that are already owned by the Optionee with a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Common Shares as to which such Option will be exercised;

(b)                                  By delivering (on a form prescribed by the Company) an irrevocable direction to a securities broker approved by the Company to sell all or part of the Common Shares being purchased under the Plan and to deliver all or part of the sales proceeds to the Company;

(c)                                   Subject to such conditions and requirements as the Administrator may impose from time to time, through a net exercise procedure; or

(d)                                  Through any other form or method consistent with applicable laws, regulations and rules.

ARTICLE 6.   STOCK APPRECIATION RIGHTS .

6.1                                SAR Agreement .  Each grant of a SAR under the Plan shall be evidenced by a SAR Agreement between the Optionee and the Company.  Such SAR shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan.  The provisions of the various SAR Agreements entered into under the Plan need not be identical.

6.2                                Number of Shares .  Each SAR Agreement shall specify the number of Common Shares to which the SAR pertains, which number shall adjust in accordance with Article 9.

6.3                                Exercise Price .  Each SAR Agreement shall specify the Exercise Price, which shall in no event be less than 100% of the Fair Market Value of a Common Share on the date of grant.  The preceding sentence shall not apply to a SAR that is a Substitute Award granted in a manner that would satisfy the requirements of Code Section 409A.

6.4                                Exercisability and Term .  Each SAR Agreement shall specify the date when all or any installment of the SAR is to become vested and exercisable; provided that with respect to 95% of the shares available for issuance under the Plan on April 4, 2019, the SAR shall not become exercisable prior to the Optionee completing at least one year of Service following the grant of such SAR.  Notwithstanding the foregoing, a SAR Agreement may provide for accelerated exercisability in the event of the Optionee’s death or disability.  The SAR Agreement shall also specify the term of the SAR; provided that except to the extent necessary to comply with applicable foreign law, the term of a SAR shall not exceed 7 years from the date of grant.

6.5                                Exercise of SARs .  Upon exercise of a SAR, the Optionee (or any person having the right to exercise the SAR after his or her death) shall receive from the Company (a) Common Shares, (b) cash or (c) a combination of Common Shares and cash, as the Administrator shall determine.  The amount of cash and/or the Fair Market Value of Common Shares received upon exercise of SARs shall, in the aggregate, not exceed the amount by which the Fair Market Value (on the date of surrender) of the Common Shares subject to the SARs exceeds the Exercise Price.  If, on the date when a SAR expires, the Exercise Price is less than the Fair Market Value on such date but any portion of such SAR has not been exercised or surrendered, then such SAR shall automatically be deemed to be exercised as of such date with respect to such portion.  A SAR Agreement may also provide for an automatic exercise of the SAR on an earlier date.

6.6                                Death of Optionee .  After an Optionee’s death, any vested and exercisable SARs held by such Optionee may be exercised by his or her beneficiary or beneficiaries.  Each Optionee may designate one or more beneficiaries for this purpose by filing the prescribed form with the Company.  A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Optionee’s death.  If no beneficiary was designated or if no designated beneficiary survives the Optionee, then any vested and exercisable SARs held by the Optionee at the time of his or her death may be exercised by his or her estate.

6.7                                Modification or Assumption of SARs .  Within the limitations of the Plan, the Administrator may modify, extend or assume outstanding SARs or may accept the cancellation of outstanding SARs (whether granted by the Company or by another issuer) in return for the grant

10

of new SARs for the same or a different number of shares and at the same or a different exercise price or in return for the grant of a different type of Award.  The foregoing notwithstanding, no modification of a SAR shall, without the consent of the Optionee, impair his or her rights or obligations under such SAR. Notwithstanding anything in this Plan to the contrary, and except for the adjustment provided in Article  9, neither the Committee nor any other person may: (a) decrease the exercise price of any outstanding SAR after the date of grant, (b) cancel or allow an Optionee to surrender an outstanding SAR to the Company in exchange for cash or as consideration for the grant of a new SAR with a lower exercise price or the grant of another Award the effect of which is to reduce the exercise price of any outstanding SAR, or (c) take any other action with respect to a SAR that would be treated as a repricing under the rules and regulations of the Nasdaq Stock Market (or such other principal U.S. national securities exchange on which the Common Shares are traded).

ARTICLE 7.   RESTRICTED SHARES .

7.1                                Restricted Stock Agreement .  Each grant of Restricted Shares under the Plan shall be evidenced by a Restricted Stock Agreement between the recipient and the Company.  Such Restricted Shares shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan.  The provisions of the various Restricted Stock Agreements entered into under the Plan need not be identical.

7.2                                Payment for Awards .  Restricted Shares may be sold or awarded under the Plan for such consideration as the Administrator may determine, including (without limitation) cash, cash equivalents, property, cancellation of other equity awards, full-recourse promissory notes, past services and future services, and such other methods of payment as are permitted by applicable law.

7.3                                Vesting Conditions .  Each Award of Restricted Shares shall be subject to vesting and/or other conditions as the Administrator may determine; provided that, the Restricted Shares will not vest prior to the holder completing at least one year of Service following the grant of such Award. Notwithstanding the foregoing,  a Restricted Stock Agreement may provide for accelerated exercisability in the event of the holder’s death or disability.  Vesting shall occur, in full or in installments, upon satisfaction of the conditions specified in the Restricted Stock Agreement.  Such conditions, at the Administrator’s discretion, may include one or more Performance Goals.

7.4                                Voting and Dividend Rights .  The holders of Restricted Shares awarded under the Plan shall have the same voting, dividend and other rights as the Company’s other stockholders, unless the Administrator otherwise provides.  A Restricted Stock Agreement, however, shall require that any cash dividends paid on Restricted Shares (a) be accumulated and paid when such Restricted Shares vest, or (b) be invested in additional Restricted Shares.  Such additional Restricted Shares shall be subject to the same conditions and restrictions as the shares subject to the Stock Award with respect to which the dividends were paid.  If any dividends or other distributions are paid in Common Shares, such Common Shares shall be subject to the same restrictions on transferability, vesting conditions and forfeitability as the Restricted Shares with respect to which they were paid.

11

ARTICLE 8.   STOCK UNITS .

8.1                                Stock Unit Agreement .  Each grant of Stock Units under the Plan shall be evidenced by a Stock Unit Agreement between the recipient and the Company.  Such Stock Units shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan.  The provisions of the various Stock Unit Agreements entered into under the Plan need not be identical.

8.2                                Payment for Awards .  To the extent that an Award is granted in the form of Stock Units, no cash consideration shall be required of the Award recipients.

8.3                                Vesting Conditions .  Each Award of Stock Units shall be subject to vesting, as determined by the Administrator.  Vesting shall occur, in full or in installments, upon satisfaction of the conditions specified in the Stock Unit Agreement; provided that the Stock Units will not vest prior to the holder completing at least one year of Service following the grant of such Stock Unit.  Notwithstanding the foregoing,  a Stock Unit Agreement may provide for accelerated exercisability in the event of the holder’s death or disability.  Such conditions, at the Administrator’s discretion, may include one or more Performance Goals.

8.4                                Voting and Dividend Rights .  The holders of Stock Units shall have no voting rights.  Prior to settlement or forfeiture, Stock Units awarded under the Plan may, at the Administrator’s discretion, provide for a right to dividend equivalents.  Such right entitles the holder to be credited with an amount equal to all cash dividends paid on one Common Share while the Stock Unit is outstanding.  Dividend equivalents shall be converted into additional Stock Units.  Settlement of dividend equivalents may be made in the form of cash, in the form of Common Shares, or in a combination of both.  If any dividend equivalents are paid with respect to Stock Units, then such dividend equivalents shall be subject to the same conditions, vesting schedule and restrictions as the Stock Units to which they attach.

8.5                                Form and Time of Settlement of Stock Units .  Settlement of vested Stock Units may be made in the form of (a) cash, (b) Common Shares or (c) any combination of both, as determined by the Administrator.  The actual number of Stock Units eligible for settlement may be larger or smaller than the number included in the original Award, based on predetermined performance factors, including Performance Goals.  Methods of converting Stock Units into cash may include (without limitation) a method based on the average Fair Market Value of Common Shares over a series of trading days.  Vested Stock Units shall be settled in such manner and at such time(s) as specified in the Stock Unit Agreement.  Until an Award of Stock Units is settled, the number of such Stock Units shall be subject to adjustment pursuant to Article 9.

8.6                                Death of Recipient .  Any Stock Units that become payable after the recipient’s death shall be distributed to the recipient’s beneficiary or beneficiaries.  Each recipient of Stock Units under the Plan may designate one or more beneficiaries for this purpose by filing the prescribed form with the Company.  A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Award recipient’s death.  If no beneficiary was designated or if no designated beneficiary survives the Award recipient, then any Stock Units that become payable after the recipient’s death shall be distributed to the recipient’s estate.

12

8.7                                Modification or Assumption of Stock Units .  Within the limitations of the Plan, the Administrator may modify or assume outstanding stock units or may accept the cancellation of outstanding stock units (whether granted by the Company or by another issuer) in return for the grant of new Stock Units for the same or a different number of shares or in return for the grant of a different type of Award.  The foregoing notwithstanding, no modification of a Stock Unit shall, without the consent of the Participant, impair his or her rights or obligations under such Stock Unit.

8.8                                Creditors’ Rights .  A holder of Stock Units shall have no rights other than those of a general creditor of the Company.  Stock Units represent an unfunded and unsecured obligation of the Company, subject to the terms and conditions of the applicable Stock Unit Agreement.

ARTICLE 9.   ADJUSTMENTS; DISSOLUTIONS AND LIQUIDATIONS; CORPORATE TRANSACTIONS .

9.1                                Adjustments .  In the event of a subdivision of the outstanding Common Shares, a declaration of a dividend payable in Common Shares, a combination or consolidation of the outstanding Common Shares (by reclassification or otherwise) into a lesser number of Common Shares or any other increase or decrease in the number of issued Common Shares effected without receipt of consideration by the Company, proportionate adjustments shall automatically be made to the following:

(a)                                  The number and kind of shares available for issuance under Article 3, including the numerical share limits in Articles 3.1 and 3.5;

(b)                                  The number and kind of shares covered by each outstanding Option, SAR and Stock Unit; or

(c)                                   The Exercise Price applicable to each outstanding Option and SAR, and the repurchase price, if any, applicable to Restricted Shares.

In the event of a declaration of an extraordinary dividend payable in a form other than Common Shares in an amount that has a material effect on the price of Common Shares, a recapitalization, a spin-off or a similar occurrence, the Administrator may make such adjustments as it, in its sole discretion, deems appropriate to the foregoing.  Any adjustment in the number of shares subject to an Award under this Article 9.1 shall be rounded down to the nearest whole share, although the Administrator in its sole discretion may make a cash payment in lieu of a fractional share. Except as provided in this Article 9, a Participant shall have no rights by reason of any issuance by the Company of stock of any class or securities convertible into stock of any class, any subdivision or consolidation of shares of stock of any class, the payment of any stock dividend or any other increase or decrease in the number of shares of stock of any class.

9.2                                Dissolution or Liquidation .  To the extent not previously exercised or settled, Options, SARs and Stock Units shall terminate immediately prior to the dissolution or liquidation of the Company.

9.3                                Corporate Transactions .  In the event that the Company is a party to a merger, consolidation, or a Change in Control (other than one described in Article 14.6(d)), all Common

13

Shares acquired under the Plan and all Awards outstanding on the effective date of the transaction shall be treated in the manner described in the definitive transaction agreement (or, in the event the transaction does not entail a definitive agreement to which the Company is party, in the manner determined by the Administrator (in accordance with this Article 9.3), with such determination having final and binding effect on all parties), which agreement or determination need not treat all Awards (or portions thereof) in an identical manner.  The  treatment specified in the transaction agreement or by the Administrator shall include one or more of the following with respect to each outstanding Award:

(a)                                  The continuation of such outstanding Award by the Company (if the Company is the surviving entity);

(b)                                  The assumption of such outstanding Award by the surviving entity or its parent, provided that the assumption of an Option or a SAR shall comply with applicable tax requirements;

(c)                                   The substitution by the surviving entity or its parent of an equivalent  award for such outstanding Award (including, but not limited to, an award to acquire the same consideration paid to the holders of Common Shares in the transaction), provided that the substitution of an Option or a SAR shall comply with applicable tax requirements;

(d)                                  If  outstanding Awards, Options and SARs are not assumed, or equivalent awards are not substituted, by the surviving entity or its parent, then full exercisability and full vesting (with respect to performance vested Awards, Options or SARs, assuming the achievement of the maximum performance targets thereunder) of the Common Shares subject to such Awards, Options and SARs, followed by the cancellation of such Awards, Options and SARs.  The full exercisability of such Awards, Options and SARs and full vesting of such Common Shares may be contingent on the closing of such transaction.  The Optionees shall be able to exercise such Options and SARs during a period of not less than five full business days preceding the closing date of such transaction, unless (i) a shorter period is required to permit a timely closing of such merger, consolidation or Change in Control and (ii) such shorter period still offers the Optionees a reasonable opportunity to exercise such Options and SARs.  Any exercise of such Options and SARs during such period may be contingent on the closing of such transaction;

(e)                                   The cancellation of such Award and a payment to the Participant with respect to each share subject to the Award equal to the excess of (A) the value, as determined by the Administrator in its absolute discretion, of the property (including cash) received by the holder of a Common Share as a result of the transaction, over (if applicable) (B) the per-share Exercise Price of such Award (such excess, if any, the “ Spread ”).  Such payment may be made in installments and may be deferred until the date or dates when such Award would have become exercisable or the Common Shares subject to such Award would have vested.  Such payment may be subject to vesting based on the Participant’s continuing Service, provided that the vesting schedule shall not be less favorable to the Participant than the schedule under which such Award would have become exercisable or such Common Shares subject to such Award would have vested.   Such payment shall be made in the form of cash, cash equivalents, or securities of the surviving entity or its parent

having a value equal to the Spread.  In addition, any escrow, holdback, earn-out or similar provisions in the transaction agreement may apply to such payment to the same extent and in the same manner as such provisions apply to the holders of Common Shares , but only to the extent the application of such provisions does not adversely affect the status of the Award as exempt from Code Section 409A.  If the Spread applicable to an Award (whether or not vested) is zero or a negative number, then the Award may be cancelled without making a payment to the Participant. In the event that a Stock Unit or other Award is subject to Code Section 409A, the payment described in this clause (e) shall be made on the settlement date specified in the applicable Stock Unit Agreement, provided that settlement may be accelerated in accordance with Treasury Regulation Section 1.409A-3(j)(4). For purposes of this Subsection (e), the Fair Market Value of any security shall be determined without regard to any vesting conditions that may apply to such security; or

(f)                                    The assignment of any reacquisition or repurchase rights held by the Company in respect of an Award of Restricted Shares to the surviving entity or its parent, with corresponding proportionate adjustments made to the price per share to be paid upon exercise of any such reacquisition or repurchase rights.

For avoidance of doubt, the Administrator shall have the discretion to provide for the acceleration of vesting upon the occurrence of a Change in Control in the event of an involuntary termination prior to or following the Change in Control, whether or not the Award is to be assumed or replaced in the transaction, or in connection with a termination of the Participant’s Service following a transaction.

Any action taken under this Article 9.3 shall either preserve an Award’s status as exempt from Code Section 409A or comply with Code Section 409A.

ARTICLE 10.   OTHER AWARDS .

10.1                         Performance Cash Awards .  A Performance Cash Award is a cash award that may be granted subject to the attainment of specified Performance Goals during a Performance Period.  A Performance Cash Award may also require the completion of a specified period of continuous Service.  The length of the Performance Period, the Performance Goals to be attained during the Performance Period, and the degree to which the Performance Goals have been attained shall be determined conclusively by the Administrator.  Each Performance Cash Award shall be set forth in a written agreement or in a resolution duly adopted by the Administrator which shall contain provisions determined by the Administrator and not inconsistent with the Plan.  The terms of various Performance Cash Awards need not be identical.

10.2                         Other Awards .  Subject in all events to the limitations under Article 3 above as to the number of Common Shares available for issuance this Plan, the Company may grant other forms of equity-based awards not specifically described herein and may grant awards under other plans or programs where such awards are settled in the form of Common Shares issued under this Plan; provided that such other equity-based award will not vest prior to the holder completing at least one year of Service following the grant of such award. Notwithstanding the foregoing,  an award agreement may provide for accelerated exercisability in the event of the holder’s death or disability.  Such Common Shares shall be treated for all purposes under the Plan like Common

15

Shares issued in settlement of Stock Units and shall, when issued, reduce the number of Common Shares available under Article 3 .

ARTICLE 11.   LIMITATION ON RIGHTS .

11.1                         Retention Rights .  Neither the Plan nor any Award granted under the Plan shall be deemed to give any individual a right to remain a Service Provider.  The Company and its Parents, Subsidiaries and Affiliates reserve the right to terminate the Service of any Service Provider at any time, with or without cause, subject to applicable laws, the Company’s certificate of incorporation and by-laws and a written employment agreement (if any).

11.2                         Stockholders’ Rights .  Except as set forth in Article 7.4 or 8.4 above, a Participant shall have no dividend rights, voting rights or other rights as a stockholder with respect to any Common Shares covered by his or her Award prior to the time when a stock certificate for such Common Shares is issued or, if applicable, the time when he or she becomes entitled to receive such Common Shares by filing any required notice of exercise and paying any required Exercise Price.  No adjustment shall be made for cash dividends or other rights for which the record date is prior to such time, except as expressly provided in the Plan.  For the avoidance of doubt, no dividends or dividend equivalents will be paid or credited to an unexercised Option or SAR.

11.3                         Regulatory Requirements .  Any other provision of the Plan notwithstanding, the obligation of the Company to issue Common Shares under the Plan shall be subject to all applicable laws, rules and regulations and such approval by any regulatory body as may be required.  The Company reserves the right to restrict, in whole or in part, the delivery of Common Shares pursuant to any Award prior to the satisfaction of all legal requirements relating to the issuance of such Common Shares, to their registration, qualification or listing or to an exemption from registration, qualification or listing.  The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed necessary by the Company’s counsel to be necessary to the lawful issuance and sale of any Common Shares hereunder, will relieve the Company of any liability in respect of the failure to issue or sell such Common Shares as to which such requisite authority will not have been obtained.

11.4                         Transferability of Awards .   The Administrator may, in its sole discretion, permit transfer of an Award in a manner consistent with applicable law.  Unless otherwise determined by the Administrator, Awards shall be transferable by a Participant only by (a) beneficiary designation, (b) a will or (c) the laws of descent and distribution; provided that, in any event, an ISO may only be transferred by will or by the laws of descent and distribution and may be exercised during the lifetime of the Optionee only by the Optionee or by the Optionee’s guardian or legal representative. In no event may an Award be transferred for any consideration including (without limitation) in exchange for cash or securities.

11.5                         Other Conditions and Restrictions on Common Shares.  Any Common Shares issued under the Plan shall be subject to such forfeiture conditions, rights of repurchase, rights of first refusal, other transfer restrictions and such other terms and conditions as the Administrator may determine.  Such conditions and restrictions shall be set forth in the applicable Award Agreement and shall apply in addition to any restrictions that may apply to holders of Common Shares generally.  In addition, Common Shares issued under the Plan shall be subject to such

16

conditions and restrictions imposed either by applicable law or by Company policy, as adopted from time to time, designed to ensure compliance with applicable law or laws with which the Company determines in its sole discretion to comply including in order to maintain any statutory, regulatory or tax advantage .

ARTICLE 12.   TAXES .

12.1                         General .  It is a condition to each Award under the Plan that a Participant or his or her successor shall make arrangements satisfactory to the Company for the satisfaction of any federal, state, local or foreign withholding tax obligations that arise in connection with any Award granted under the Plan.  The Company shall not be required to issue any Common Shares or make any cash payment under the Plan unless such obligations are satisfied.

12.2                         Share Withholding .  To the extent that applicable law subjects a Participant to tax withholding obligations, the Administrator may permit such Participant to satisfy all or part of such obligations by having the Company withhold all or a portion of any Common Shares that otherwise would be issued to him or her or by surrendering all or a portion of any Common Shares that he or she previously acquired.  Such Common Shares shall be valued on the date when they are withheld or surrendered.  Any payment of taxes by assigning Common Shares to the Company may be subject to restrictions including any restrictions required by SEC, accounting or other rules.

12.3                         Section 162(m) Matters   The Administrator, in its sole discretion, may determine whether an Award is intended to qualify as “performance-based compensation” within the meaning of Code Section 162(m).  The Administrator may grant Awards that are based on Performance Goals but that are not intended to qualify as performance-based compensation.  With respect to any Award that is intended to qualify as performance-based compensation, the Administrator shall designate the Performance Goal(s) applicable to, and the formula for calculating the amount payable under, an Award within 90 days following commencement of the applicable Performance Period (or such earlier time as may be required under Code Section 162(m)), and in any event at a time when achievement of the applicable Performance Goal(s) remains substantially uncertain.  Prior to the payment of any Award that is intended to constitute performance-based compensation, the Administrator shall certify in writing whether and the extent to which the Performance Goal(s) were achieved for such Performance Period.  The Administrator shall have the right to reduce or eliminate (but not to increase) the amount payable under an Award that is intended to constitute performance-based compensation.

12.4                         Section 409A Matters .  Except as otherwise expressly set forth in an Award Agreement, it is intended that Awards granted under the Plan either be exempt from, or comply with, the requirements of Code Section 409A.  To the extent an Award is subject to Code Section 409A (a “ 409A Award ”), the terms of the Plan, the Award and any written agreement governing the Award shall be interpreted to comply with the requirements of Code Section 409A so that the Award is not subject to additional tax or interest under Code Section 409A, unless the Administrator expressly provides otherwise.  A 409A Award shall be subject to such additional rules and requirements as specified by the Administrator from time to time in order for it to comply with the requirements of Code Section 409A.  In this regard, if any amount under a 409A Award is payable upon a “separation from service” to an individual who is considered a “specified employee” (as each term is defined under Code Section 409A), then no such payment shall be

17

made prior to the date that is the earlier of (i) six months and one day after the Participant’s separation from service or (ii) the Participant’s death, but only to the extent such delay is necessary to prevent such payment from being subject to Code Section 409A(a)(1).

12.5                         Limitation on Liability .  Neither the Company nor any person serving as Administrator shall have any liability to a Participant in the event an Award held by the Participant fails to achieve its intended characterization under applicable tax law.

ARTICLE 13.   FUTURE OF THE PLAN .

13.1                         Term of the Plan .  The Plan, as set forth herein, shall become effective on the date of its adoption by the Board, subject to approval of the Company’s stockholders under Article 13.3 below.  The Plan shall terminate automatically 10 years after the later of (a) the date when the Board adopted the Plan or (b) the date when the Board approved the most recent increase in the number of Common Shares reserved under Article 3 that was also approved by the Company’s stockholders.  The Plan shall serve as the successor to the Predecessor Plan, and no further Awards may be made under the Predecessor Plan after the Effective Date.

13.2                         Amendment or Termination .  The Board may, at any time and for any reason, amend or terminate the Plan.  No Awards shall be granted under the Plan after the termination thereof.  The termination of the Plan, or any amendment thereof, shall not affect any Award previously granted under the Plan.

13.3                         Stockholder Approval .  To the extent required by applicable law, the Plan will be subject to the approval of the Company’s stockholders within 12 months of its adoption date.  An amendment of the Plan shall be subject to the approval of the Company’s stockholders only to the extent required by applicable laws, regulations or rules; provided, however , that an amendment to Article 3.1, the last sentence of Article 5.6 or Article 6.7 is subject to approval of the Company’s stockholders.
