forth in the definition of Performance Factors and in Section 5 of the Plan) to
such other appropriate officer of the Company, or in the case of ministerial
duties to any employee or committee comprised of employees of any Company.

All decisions, determinations and interpretations of the Committee shall be
final and binding on all persons, including the Company and the Participants (or
any person claiming any rights under the Plan from or through any Participant).
No member of the Board or the Committee shall be liable for any action taken or
determination made in good faith with respect to the Plan or any Award granted
hereunder.

Eligibility. Awards may be granted to officers and other employees of the
Company in the sole discretion of the Committee, with respect to the executive
officers of the Company, and in the sole discretion of the Chief Executive
Officer of the Company with respect to the other Participants. Unless otherwise
determined by the Committee or the Chief Executive Officer, as applicable, in
its/his sole discretion, a Participant, who commences participation in the Plan
following the commencement of a Performance Period, may participate with respect
to all outstanding Performance Periods; provided that the Awards payable with
respect to each such Performance Period shall be prorated based on the number of
days elapsed in such Performance Period.
Terms of Awards. Awards granted pursuant to the Plan shall be communicated to
Participants from time to time, and the terms and conditions of such Awards
shall be set forth therein.

General
. Not later than 90 days after the commencement of each Performance Period (but
in no case after 25% of the Performance Period has elapsed), the Committee shall
specify in writing, by resolution of the Committee or other appropriate action,
with respect to a Performance Period, the Performance Factors applicable to each
Award. Performance Factors may include a threshold level of performance below
which no payment shall be made, levels of performance at which specified
percentages of the Award shall be paid and a maximum level of performance above
which no additional payment shall be made; provided that the Committee shall
have the authority to make appropriate adjustments in the achievement of
Performance Factors under an Award to reflect the impact of extraordinary items
not reflected in such goals. Unless otherwise provided by the Committee (or its
designee) in connection with specified terminations of employment, payment in
respect of Awards shall be made only if and to the extent the Performance
Factors with respect to such Performance Period are attained.

Special Provisions Regarding Awards
. Notwithstanding anything to the contrary contained herein, in no event shall
payment in respect of Awards granted for any Performance Period of one year or
less in length be made to a Participant in an amount that exceeds two million,
five hundred thousand U.S. dollars
,
and for any other Performance Period in excess of one year, such amount
multiplied by a fraction, the numerator of which is the number of months in the
performance period and the denominator of which is twelve.

Time and Form of Payment
. Unless otherwise determined by the Committee, all payments in respect of
Awards granted under this Plan shall be made in cash (unless the Award
specifically provides for a different form of payment, in which case in such
other form of payment)
,
within a reasonable period after the end of the Performance Period, but in no
event later than June 15 of the year following the year in which such Awards are
no longer subject to substantial risk of forfeiture.

Term. The Committee shall set Performance Factors and grant Awards with respect
to each Performance Period commencing with the initial Performance Period which
shall begin April 1, 2008, and end March 31, 2009.
General Provisions.

    Compliance with Legal Requirements
    . The Plan and the granting and payment of Awards and the other obligations
    of the Company under the Plan shall be subject to all applicable federal and
    state laws, rules and regulations, and to such approvals by any regulatory
    or governmental agency as may be required.
    
    
    Transferability of Rights
    . Awards shall not be transferable by a Participant except upon the
    Participant's death following the end of the Performance Period but prior to
    the date payment is made, in which case the Award shall be transferable by
    will or the laws of descent and distribution.
    
    
    No Right To Continued Employment
    . Nothing in the Plan or in any Award granted pursuant hereto shall confer
    upon any Participant the right to continue in the employ of the Company or
    to be entitled to any remuneration or benefits not set forth in the Plan or
    to interfere with or limit in any way the right of the Company to make
    determinations with respect to or terminate such Participant's employment.
    
    
    Withholding Taxes
    . Where a Participant or other person is entitled to receive a payment
    pursuant to an Award hereunder, the Company shall have the right to withhold
    from any payment otherwise due by reason of such Award the amount of any
    taxes that the Company may be required to withhold before delivery to such
    Participant or other person, or the Company may require the Participant or
    such other person to pay such amount to the Company before delivery to such
    Participant or other person of such payment.
    
    
 a. Amendment, Termination and Duration of the Plan. The term of the Plan shall
    be five years from and including the Effective Date; provided that the Board
    or the Committee may at any time and from time to time alter, amend,
    suspend, or terminate the Plan in whole or in part. Notwithstanding the
    foregoing, no amendment shall affect adversely any of the rights of any
    Participant under any Award following the end of the Performance Period to
    which such Award relates; provided that no amendment that requires
    stockholder approval in order for the Plan to continue to comply with
    Section 162(m) of the Code shall be effective unless such amendment shall be
    approved by the requisite vote of the stockholders of the Company.
    Notwithstanding the termination of the Plan, Awards granted under the Plan
    shall remain outstanding subject to the terms of the Plan until the
    expiration of the Performance Period to which such Award relates or the
    earlier termination of the Award in accordance with the provisions of the
    Plan.
    
    Participant Rights
    . No Participant shall have any claim to be granted any Award under the
    Plan, and there is no obligation for uniformity of treatment for
    Participants. The adoption of the Plan shall not affect any other equity or
    other compensation or incentive plan in effect for the Company or an
    Affiliate, and the Plan shall not preclude the Board or Committee from
    establishing other forms of incentive compensation.
    
    
 b. Change in Control. In the event that a Participant experiences a Qualifying
    Termination (as defined below) within three (3) months following a Change in
    Control, the Company shall pay to such Participant, as soon as practicable
    following the date of such Qualifying Termination, a pro rata portion
    through the date of the Change in Control of the aggregate value of all
    Awards granted to such Participant for any Performance Period for which
    Awards are outstanding as of the Change in Control and which is uncompleted
    as of the Qualifying Termination , calculated as to each such Award based on
    actual performance through the most recently completed fiscal quarter ending
    on or prior to the date of the Change in Control and for any portion of the
    Performance Period that was to occur after the most recently completed
    fiscal ending on or prior to the date of the Change in Control, assuming the
    achievement, at the target level, of the Performance Factors established
    with respect to such Award, all as determined by the Committee, and such
    Performance Periods and the Plan shall thereafter immediately terminate with
    respect to such Participants and the Company. For purposes of this Section a
    "Qualifying Termination" shall mean (i) the Participant's involuntary
    termination of employment by the Company without Cause (as such term is
    defined in the Company's 2006 Equity Incentive Plan); provided, however,
    that a Participant shall not experience an involuntary termination of
    employment if the Participant receives an offer of employment from a
    successor company at the same or greater level of base salary and otherwise
    on substantially comparable terms and conditions and in the same
    metropolitan area as prior to the Change in Control or (ii) the
    Participant's voluntary termination of employment within 30 days following
    the relocation, without the Participant's consent, of the Participant's
    principal place of employment to a metropolitan area outside the
    metropolitan area in which the Participant's principal place of employment
    was located as of the Change in Control.
    
    Termination of Employment
    .
    
    
     i.  Unless otherwise provided by the Committee, if a Participant's
         employment is terminated as result of death, retirement at normal
         retirement age, early retirement with Company consent, or Disability
         prior to the end of the Performance Period, the Participant's Awards
         shall be cancelled, and in respect of such cancelled Award such
         Participant shall receive a pro rata portion of his or her Award that
         he or she would have received with respect to the applicable
         Performance Period based on actual performance for the Performance
         Period, which shall be payable at such time that Awards are payable to
         other Participants.
         
     ii. Unless otherwise provided by the Committee in connection with specified
         terminations of employment, if a Participant's employment terminates
         for any reason, other than death or Disability, prior to the end of a
         Performance Period, no Award shall be payable to such Participant with
         respect to such Performance Period.
         

    Unfunded Status of Awards
    . The Plan is intended to constitute an "unfunded" plan for incentive
    compensation. With respect to any payments not yet made to a Participant
    pursuant to an Award, nothing contained in the Plan or any Award shall give
    any such Participant any rights that are greater than those of a general
    creditor of the Company.
    
    
    Governing Law
    . The Plan and all determinations made and actions taken pursuant hereto
    shall be governed by the laws of the State of Delaware without giving effect
    to the conflict of laws principles thereof.
    
    
    Beneficiary
    . A Participant may file with the Company a written designation of a
    beneficiary on such form as may be prescribed by the Committee and may, from
    time to time, amend or revoke such designation. If no designated beneficiary
    survives the Participant and an Award is payable to the Participant's
    beneficiary, the executor or administrator of the Participant's estate shall
    be deemed to be the grantee's beneficiary.
    
    
    Successor to the Company
    . Unless otherwise agreed by the Company in an applicable agreement, any
    successor to the Company shall be required to (i) expressly assume the
    Company's obligations under the Plan in connection with a Change in Control,
    and (ii) honor the Company's obligations under the Plan and any Award
    granted thereunder, without adverse alteration to the rights of any
    Participant, with respect to the Performance Period during which such Change
    in Control occurs.
    
    
    Interpretation
    . The Plan is designed sand intended to comply, to the extent applicable,
    with Sections 162(m) and 409A of the Code, and all provisions hereof shall
    be construed in a manner to so comply.
