Administration of the Plan.

3.1
The Administrator. This Plan shall be administered by the Administrator;
provided, however, that, with respect to Participants who are not Executive
Officers, the Chief Executive Officer may delegate to one or more officers of
the Company or any Subsidiary some or all of the Administrator’s authority under
this Plan with respect to one or more Awards.

3.2
Powers of the Administrator. Subject to the express provisions of this Plan and,
as applicable, the 2004 Plan, the Administrator shall have responsibility for
the administration of this Plan in accordance with its terms, including without
limitation the authority to (i) determine eligibility to participate in this
Plan and, from those individuals determined to be eligible, the particular
individuals who will receive an Award under this Plan, and (ii) establish the
terms and conditions applicable to each Award. The Administrator shall have the
authority to construe and interpret this Plan and any agreements or other
document relating to Awards under this Plan, may adopt rules and regulations
relating to the administration of this Plan, and shall exercise all other duties
and powers conferred on it by this Plan. Any determination by the Administrator
shall be final and binding on all Participants.

4.
Bonus Provisions.

4.1
Determination of Company Bonus. The Company Bonus payable with respect to an
Award (if any) will be determined under clauses (a), (b), (c) and (d) of this
Section 4.1.

(a).
Company Performance Percentage. The Administrator shall establish one or more
Company Performance Criteria for the applicable Performance Period and shall
provide a formula for measuring the Company’s performance during such
Performance Period relative to such Company

3

--------------------------------------------------------------------------------

Performance Criteria. The formula provided by the Administrator shall yield a
measurement of performance ranging from a minimum of zero percent (0%) to two
hundred percent (200%), or such other maximum as the Administrator shall
determine. At the end of the applicable Performance Period and based upon the
formula established by the Administrator, the Administrator shall determine the
performance percentage achieved by the Company’s performance during such
Performance Period (the “Company Performance Percentage”).
(b).
Funding Percentage. In the event that the Company Performance Percentage for a
Performance Period equals or exceeds such percentage as the Administrator
determines in its discretion, the Administrator may allocate a portion of the
Company Performance Percentage as it determines to be used for determining a
Discretionary Bonus to be paid to Participants at the end of the applicable
Performance Period pursuant to Section 4.2 below (such percentage is hereinafter
referred to as the “Discretionary Funding Percentage”). The remainder of the
Company Performance Percentage not allocated by the Administrator pursuant to
the foregoing sentence shall equal the “Company Funding Percentage” and shall be
used for determining the Company Bonus to be paid to Participants at the end of
the applicable Performance Period pursuant to Section 4.1(d) below. By way of
example and assuming the Administrator allocates ten percent (10%) of the
Company Performance Percentage to the Discretionary Funding Percentage, if the
Company Performance Percentage for a Performance Period equals one hundred and
fifty percent (150%), a Discretionary Funding Percentage may be allocated by the
Administrator for such Performance Period in an amount not to exceed fifteen
percent (15%) and, in such case, the Company Funding Percentage for such
Performance Period shall not be less than one hundred and thirty-five percent
(135%).

(c).
Individual Performance. At the end of each Performance Period, the Administrator
shall evaluate, or cause to be evaluated, the performance of each Participant
during the applicable Performance Period and shall designate a measurement for
such Participant’s performance during the applicable Performance Period ranging
from a minimum of zero (0.0) up to a maximum of three (3.0), or such other
amount as determined by the Administrator (the “Individual Performance Factor”).
The Individual Performance Factor applicable to a Participant shall be
determined in accordance with instructions and/or procedures established from
time to time by the Administrator.

(d).
Bonus Determination. The amount of the Company Bonus payable to a Participant
for the applicable Performance Period shall be determined by multiplying (i) the
Participant’s Target Bonus, by (ii) the Company Funding Percentage, by (iii) the
Individual Performance Factor applicable to such

4

--------------------------------------------------------------------------------

Participant; provided, however, the Administrator may in its sole discretion
increase, reduce or eliminate such Bonus based on such factors as the
Administrator determines appropriate; provided, further, that in no event shall
(x) the Company Bonus for any Award exceed an amount equal to three (3) times
the Target Bonus for such Award, or (y) the aggregate amount of all Company
Bonuses under this Plan for a Performance Period exceed the Company Bonus Pool
(defined below) for that Performance Period. For purposes hereof, “Company Bonus
Pool” means the amount obtained by multiplying the aggregate of all Target
Bonuses for Awards granted during the Performance Period (excluding Awards that
terminate pursuant to Section 4.4) by the Company Funding Percentage.
4.2
Determination of Discretionary Bonuses. In addition to any Company Bonus payable
to a Participant pursuant to Section 4.1 above and subject to the limitations in
this Section 4.2, the Administrator may award Discretionary Bonuses to one or
more Participants in any amount as it determines appropriate in its sole
discretion. The aggregate of all Discretionary Bonuses payable by the
Administrator during a Performance Period shall not exceed the Discretionary
Bonus Pool (defined below) for that Performance Period. For purposes hereof,
“Discretionary Bonus Pool” means the amount obtained by multiplying the
aggregate of all Target Bonuses for Awards granted during the Performance Period
(excluding Awards that terminate pursuant to Section 4.4) by the Discretionary
Funding Percentage.

4.3
Newly Hired Employees. Unless otherwise provided by the Administrator, in the
event that an individual commences employment with the Company during a
Performance Period at a level that has been determined by the Company to be
eligible for participation in this Plan for that Performance Period, such
individual shall be eligible to receive a Bonus under this Plan for that
Performance Period in accordance with this Section 4, provided that such
individual’s Target Bonus shall be based on the Eligible Wages the individual
actually received during that Performance Period. In addition, an individual
must be employed by the Company for at least one month of a Performance Period
to be eligible to receive a Bonus during such Performance Period.

4.4
Termination of Employment.

(a).
Unless otherwise expressly provided under a separate Company plan or written
contract with the Company, in the event that a Participant’s employment with the
Company and its Subsidiaries terminates (regardless of the reason for such
termination of employment, whether voluntarily or involuntarily, with or without
cause, or due to the Participant’s death or disability) at any time during the
Performance Period applicable to an Award granted to that Participant, such
Award shall immediately terminate upon such termination of employment, and the
Participant shall not be entitled to any Bonus payment in respect of such Award.

5

--------------------------------------------------------------------------------

(b).
Unless otherwise expressly provided under a separate Company plan or written
contract with the Company, in the event that a Participant’s employment with the
Company and its Subsidiaries terminates (regardless of the reason for such
termination of employment, whether voluntarily or involuntarily, with or without
cause, or due to the Participant’s death or disability) after the close of the
Performance Period but prior to the Company paying out Bonuses to Participants
with respect to such Performance Period, such Participant’s eligibility for a
Bonus shall immediately terminate upon such termination of employment, and the
Participant shall not be entitled to any Bonus payment.

4.5
Adjustments; Early Termination. The Administrator shall have discretion to
adjust the performance measures, performance goals, relative weights of the
measures, and other provisions of then-outstanding Awards under this Plan to
reflect (1) any material change in corporate capitalization, any corporate
transaction (such as a reorganization, combination, separation, merger,
acquisition, or any combination of the foregoing), or any complete or partial
liquidation of the Company, (2) any change in accounting policies or practices
or applicable law, (3) the effects of any special charges to the Company’s
earnings, or (4) any other special, material or nonrecurring circumstances or
extraordinary events. Notwithstanding any other provision herein, the
Administrator shall have discretion to terminate any Award granted hereunder in
connection with any merger, reorganization or other corporation transaction, as
the Administrator may determine in its sole discretion.

4.6
Administrator Discretion to Determine Bonuses. The Administrator has the sole
discretion to determine the performance goals and criteria for each Award (in
accordance with this Section 4) and whether all or any portion of the amount so
calculated will be paid, subject in all cases to the terms, conditions and
limits of this Plan and of any other written commitment authorized by the
Company. To this same extent, the Administrator may at any time establish
additional conditions and terms of an Award or for the payment of Bonuses
(including but not limited to the achievement of other financial, strategic or
individual goals, which may be objective or subjective) as the Administrator may
deem desirable in carrying out the purposes of this Plan and may take into
account such other factors as the Administrator deems appropriate in
administering any aspect of this Plan.

4.7
Form and Time of Payment. Any Bonuses shall be paid in cash (subject to tax
withholding pursuant to Section 5.5) as soon as reasonably practicable following
the determination of the Bonus amount pursuant to Sections 4.1 and 4.2 of this
Plan, but in no event later than (a) March 15 of the year following the year in
which such Bonus is earned, or (b) if later, the last day of the period ending
on the 15th day of the third month following the end of the Company’s fiscal
year in which such Bonus is earned, in each case, in accordance with Treasury
Regulation Section 1.409A-1(b)(4)(i).

5.
General Provisions.

5.1
Rights of Participants.

(c).
No Right to Awards or Continued Employment. Neither the establishment of this
Plan, nor the provision for or payment of any amounts hereunder, nor any action
of the Company or any of its officers, employees or directors in respect of this
Plan shall be held or construed to confer upon any person any legal right to
receive, an Award or any other benefit under the Plan. Nothing contained in this
Plan (or in any other documents evidencing any Award under this Plan) shall
confer upon any employee or Participant any right to continue in the employ of
the Company or any Subsidiary, constitute any contract or agreement of
employment, nor shall interfere in any way with the right of the Company or any
Subsidiary to change any person’s compensation or other benefits, or to
terminate his employment, with or without cause. Nothing in this Section 5.1(a),
however, is intended to adversely affect any express independent right of such
person under a separate written employment contract.

(d).
Plan Not Funded. Awards payable under this Plan shall be payable from the
general assets of the Company, and no special or separate reserve, fund or
deposit shall be made to assure payment of such Awards. No Participant or other
person shall have any right, title or interest in any fund or in any specific
asset of the Company by reason of any Award hereunder. Neither the provisions of
this Plan (nor of any related documents), nor the creation or adoption of this
Plan, nor any action taken pursuant to the provisions of this Plan shall create,
or be construed to create, a trust of any kind or a fiduciary relationship
between the Company and any Participant or other person. To the extent that a
Participant or other person acquires a right to receive payment pursuant to any
Award hereunder, such right shall be no greater than the right of any unsecured
general creditor of the Company.

5.2
Non-Transferability of Benefits and Interests. Except as expressly provided by
the Administrator, all Awards are non-transferable, and no benefit payable under
this Plan shall be subject in any manner to sale, transfer, anticipation,
alienation, assignment, pledge, encumbrance or charge.

5.3
Discretion of Company and Administrator. Any decision made or action taken by,
or inaction of, the Company or the Administrator arising out of or in connection
with the creation, amendment, construction, administration, interpretation and
effect of the Plan that is within its authority hereunder or applicable law
shall be within the absolute discretion of such person or entity and shall be
conclusive and binding upon all persons. Neither the Administrator, nor any
person acting at the direction thereof, nor any member of the Company’s Board of
Directors shall be liable for any act,

omission, interpretation, construction or determination made in good faith in

validity and effect of the provisions of this Plan shall be determined in
accordance with the laws of the State of Delaware, without regard to the choice
of law principles thereof.

Tax Withholding. Upon the payment of any Bonus, the Company shall have the right
to deduct the amount of any federal, state or local taxes that the Company or
any Subsidiary may be required to withhold with respect to such payment.

No Vested Rights; Amendments, Suspension or Termination of Plan. No Participant
shall have, at any time, a vested right to any benefit under this Plan. The
Company or the Administrator may at any time terminate, amend, modify or suspend
this Plan, in whole or in part and/or with respect to any or all Participants.

Non-Exclusivity of Plan. Nothing in this Plan shall limit or be deemed to limit
the authority of the Company to grant awards or authorize any other compensation
under any other plan or authority.

5.9
Code Section 409A. Company’s intent is that any payments and benefits paid under
this Plan be exempt from, or comply with, Section 409A of the Code, and
accordingly, to the maximum extent permitted, this Plan shall be interpreted and
administered to be in accordance therewith. Each payment under this Plan shall
be construed as a separate identified payment for purposes of Section 409A of
the Code, and any payments described in this Plan that are due within the “short
term deferral period” as defined in Section 409A of the Code shall not be
