who shall be Participants for any Performance Period. The Committee, in its sole
discretion, also may designate as Participants one or more individuals (by name
or position) who are expected to become Employees during a Performance Period.

guaranteed or assured of being selected for participation in any subsequent
Performance Period.

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

Exhibit 10.10

3.2 Determination of Performance Goals
The Committee, in its sole discretion, shall establish the Performance Goals for
each Participant for the Performance Period. Such Performance Goals shall be set
forth in writing. The Performance Goals may differ from Participant to
Participant and from award to award. The Committee shall also determine and set
forth in writing whether any significant elements shall be included in or
excluded from the calculation of any Performance Goal with respect to any
Participants, including (a) restructurings, discontinued operations,
extraordinary items, and other unusual or non-recurring charges, (b) an event
either not directly related to the operations of the Company or not within the
reasonable control of the Company’s management, or (c) the cumulative effects of
tax or accounting changes in accordance with U.S. generally accepted accounting
principles.
3.3 Determination of Target Awards
The Committee, in its sole discretion, shall establish a Target Award for each
Participant. Each Participant’s Target Award shall be determined by the
Committee in its sole discretion, and each Target Award shall be set forth in
writing. The Target Award may be denominated by reference to a formula, a
percentage of base salary, or a fixed dollar amount.
3.4 Determination of Payout Formula or Formulae
The Committee, in its sole discretion, shall establish a Payout Formula or
Formulae for purposes of determining the Actual Award (if any) payable to each
Participant. Each Payout Formula shall (a) be in writing, (b) be based on a
comparison of actual performance to the Performance Goals, (c) provide for the
payment of a Participant’s Target Award if the Performance Goals for the
Performance Period are achieved at the predetermined level, and (d) provide for
the payment of an Actual Award greater than or less than the Participant’s
Target Award, depending upon the extent to which actual performance exceeds or
falls below the Performance Goals. Notwithstanding the preceding, no
Participant’s Actual Award(s) under the Plan may, for any period of three (3)
consecutive Fiscal Years, exceed $15,000,000.
3.5 Date for Determinations
The Committee shall make all determinations under Section 3.1 through 3.4 on or
before the latest possible date that will not jeopardize a Target Award or
Actual Award’s qualification as performance-based compensation under Section
162(m) of the Code. For Fiscal Year Performance Periods, such date is expected
to be the earlier of (i) 90 days after the commencement of each Performance
Period or (ii) the expiration of 25% of the Performance Period.
3.6 Determination of Actual Awards
After the end of each Performance Period, the Committee shall certify in writing
(for example, in its meeting minutes) the extent to which the Performance Goals
applicable to each Participant for the Performance Period were achieved or
exceeded, as determined by the Committee. The Actual Award for each Participant
shall be determined by applying the Payout Formula to the level of actual
performance which has been certified by the Committee. Notwithstanding any
contrary provision of the Plan, the Committee, in its sole discretion, may (a)
eliminate or reduce the Actual Award payable to any Participant below that which
otherwise would be payable under the Payout Formula, and (b) determine what
Actual Award, if any, will be paid in the event of a Termination of Service
prior to the end of the Performance Period.

SECTION 4.
PAYMENT OF AWARDS
4.1 Right to Receive Payment
Each Actual Award that may become payable under the Plan shall be paid solely
from the general assets of the Company. Nothing in this Plan shall be construed
to create a trust or to establish or evidence any Participant’s claim of any
right other than as an unsecured general creditor with respect to any payment to
which he or she may be entitled.

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

Exhibit 10.10

4.2 Timing of Payment
Payment of each Actual Award shall be made as soon as practicable, but no later
than two and one-half months after the end of the Performance Period during
which the Actual Award was earned.
4.3 Form of Payment
Each Actual Award shall be paid in cash (or its equivalent) or Shares in a
single lump sum, except as otherwise determined by the Committee, in its sole
discretion. To the extent an Actual Award, in whole or in part, is payable in
Shares, such Shares shall be granted under the Company’s 2012 Long-Term
Incentive Plan or such other shareholder approved plan of the Company providing
for payment of Shares as the Committee may determine. If (a) an Actual Award is
paid in Shares or (b) a Target Award denominated in Shares is paid in cash, the
number of Shares to be determined shall be determined by dividing the cash
amount otherwise payable by the closing per share selling price for Shares as
quoted on the New York Stock Exchange on the date payment of the Actual Award is
to be made.
4.4 Recoupment of Awards
Notwithstanding any contrary provision of this Plan, a Participant’s rights with
respect to any Actual Award hereunder shall be subject to the Company’s clawback
policy as may be established and/or amended from time to time (the “Clawback
Policy”). The Board or the Committee may require the Participant to forfeit,
return, or reimburse the Company for, all or a portion of any Actual Award paid
to the Participant pursuant to the terms of the Clawback Policy or as necessary
or appropriate to comply with applicable laws (including, without limitation,
Section 10D of the 1934 Act and any applicable rules and regulations promulgated
thereunder from time to time by the U.S. Securities and Exchange Commission).
Any recoupment of an Actual Award made with respect to a Participant may be in
addition to any other remedies that may be available to the Company under
applicable law, including disciplinary actions up to and including termination
of employment.
4.5 Payment in the Event of Death
If a Participant dies prior to the payment of an Actual Award earned by him or
her prior to death for a prior Performance Period, the Award shall be paid to
administrator or representative of his or her estate, except as provided in
Section 6.6.

SECTION 5.
ADMINISTRATION
5.1 Committee is the Administrator
The Plan shall be administered by the Committee. The Committee shall consist of
not less than two (2) members of the Board. The members of the Committee shall
be appointed from time to time by, and serve at the pleasure of, the Board. Each
member of the Committee shall qualify as an “outside director” under Section
162(m) of the Code. If it is later determined that one or more members of the
Committee do not so qualify, actions taken by the Committee prior to such
determination shall be valid despite such failure to qualify. Unless otherwise
determined by the Board, the Plan shall be administered by the Compensation
Committee of the Board.
5.2 Committee Authority
It shall be the duty of the Committee to administer the Plan in accordance with
the Plan’s provisions. The Committee shall have all powers and discretion
necessary or appropriate to administer the Plan and to control its operation,
including, but not limited to, the power to (a) determine which Employees shall
be granted awards, (b) prescribe the terms and conditions of awards, (c)
interpret the Plan and the awards, (d) adopt such procedures and subplans as are
necessary or appropriate to permit participation in the Plan by Employees who
are foreign nationals or employed outside of the United States, (e) adopt rules
for the administration, interpretation and application of the Plan as are
consistent therewith, and (f) interpret, amend or revoke any such rules.

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

Exhibit 10.10

5.3 Decisions Binding
All interpretations, determinations and decisions made by the Committee, the
Board, and any delegate of the Committee pursuant to the provisions of the Plan
shall be final, conclusive, and binding on all persons, and shall be given the
maximum deference permitted by law.
5.4 Delegation by the Committee
The Committee, in its sole discretion and on such terms and conditions as it may
provide, may delegate all or part of its authority and powers under the Plan to
one or more directors and/or officers of the Company; provided, however, that
the Committee may delegate its authority and powers only to the extent
consistent with applicable laws (including the provisions of Section 162(m) of
the Code to the extent applicable) and the rules and regulations of the
principal securities market on which the Company’s securities are listed or
qualified for trading.

SECTION 6.
GENERAL PROVISIONS
6.1 Tax Withholding
The Company (or an Affiliate) shall withhold all applicable taxes from any
Actual Award, including any federal, state, local and other taxes (including,
but not limited to, the Participant’s FICA and SDI obligations).
6.2 No Effect on Employment or Service
Nothing in the Plan shall interfere with or limit in any way the right of the
Company to terminate any Participant’s employment or service at any time, with
or without cause. For purposes of the Plan, transfer of employment of a
Participant between the Company and any one of its Affiliates (or between
Affiliates) shall not be deemed a termination of employment or service.
Employment with the Company and its Affiliates is on an at-will basis only. The
Company and its Affiliates expressly reserve the right, which may be exercised
at any time and without regard to when during a Performance Period such exercise
occurs, to terminate any individual’s employment or service with or without
cause, and to treat him or her without regard to the effect which such treatment
might have upon him or her as a Participant.
6.3 Participation
No Employee shall have the right to be selected to receive an award under this
Plan, or, having been so selected, to be selected to receive a future award.
6.4 Indemnification
Each person who is or shall have been a member of the Committee, or of the
Board, shall be indemnified and held harmless by the Company against and from
(a) any loss, cost, liability, or expense that may be imposed upon or reasonably
incurred by him or her in connection with or resulting from any claim, action,
suit, or proceeding to which he or she may be a party or in which he or she may
be involved by reason of any action taken or failure to act under the Plan or
any award, and (b) from any and all amounts paid by him or her in settlement
thereof, with the Company’s approval, or paid by him or her in satisfaction of
any judgment in any such claim, action, suit, or proceeding against him or her,
provided he or she shall give the Company an opportunity, at its own expense, to
handle and defend the same before he or she undertakes to handle and defend it
on his or her own behalf. The foregoing right of indemnification shall not be
exclusive of any other rights of indemnification to which such persons may be
entitled under the Company’s Certificate of Incorporation or Bylaws, by
contract, as a matter of law, or otherwise, or under any power that the Company
may have to indemnify them or hold them harmless.
6.5 Successors
All obligations of the Company under the Plan, with respect to awards granted
hereunder, shall be binding on any successor to the Company, whether the
existence of such successor is the result of a direct or indirect purchase,
merger, consolidation, or otherwise, of all or substantially all of the business
or assets of the Company.

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

Exhibit 10.10

6.6 Beneficiary Designations
a. Designation. Each Participant may, pursuant to such uniform and
nondiscriminatory procedures as the Committee may specify from time to time,
designate one or more beneficiaries to receive any Actual Award payable to the
Participant at the time of his or her death. Notwithstanding any contrary
provision of this Section 6.6 shall be operative only after (and for so long as)
the Committee determines (on a uniform and nondiscriminatory basis) to permit
the designation of beneficiaries.
b. Changes. A Participant may designate different beneficiaries (or may revoke a
prior beneficiary designation) at any time by delivering a new designation (or
revocation of a prior designation) in like manner. Any designation or revocation
shall be effective only if it is received by the Committee. However, when so
received, the designation or revocation shall be effective as of the date the
designation or revocation is executed (whether or not the Participant still is
living), but without prejudice to the Committee on account of any payment made
before the change is recorded. The last effective designation received by the
Committee shall supersede all prior designations.
c. Failed Designation. If the Committee does not make this Section 6.6 operative
or if Participant dies without having effectively designated a beneficiary, the
Participant’s Account shall be payable to the general beneficiary shown on the
records of the Employer. If no beneficiary survives the Participant, the
Participant’s Account shall be payable to his or her estate.
6.7 Nontransferability of Awards
No award granted under the Plan may be sold, transferred, pledged, assigned, or
otherwise alienated or hypothecated, other than by will, by the laws of descent
and distribution, or to the limited extent provided in Section 6.6. All rights
with respect to an award granted to a Participant shall be available during his
or her lifetime only to the Participant.
6.8 Deferrals
The Committee, in its sole discretion, may permit a Participant to defer receipt
of the payment of cash or Shares that would otherwise be delivered to a
Participant under the Plan. Any such deferral elections shall be subject to such
rules and procedures as shall be determined by the Committee in its sole
discretion and shall be under a plan or arrangement consistent with the
requirements of Section 409A of the Code.
6.9 Section 409A
It is intended that all bonuses payable under this Plan will be exempt from the
requirements of Section 409A pursuant to the “short-term deferral” exemption or,
in the alternative, will comply with the requirements of Section 409A so that
none of the payments and benefits to be provided under this Plan will be subject
to the additional tax imposed under Section 409A, and any ambiguities or
ambiguous terms herein shall be interpreted to so comply or be exempt. Each
payment and benefit payable under this Plan is intended to constitute a separate
payment for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. The
Company may, in good faith and without the consent of any Participant, make any
amendments to this Plan and take such reasonable actions which it deems
necessary, appropriate or desirable to avoid imposition of any additional tax or
income recognition under Section 409A prior to actual payment to the
Participant. In no event will the Company reimburse any Participant for any
taxes or costs that may be imposed on or incurred by the Participant as a result
of Section 409A. For purposes of the Plan, “Section 409A” means Section 409A of
the Internal Revenue Code of 1986, as amended, and any final Treasury
Regulations or other Internal Revenue Service guidance thereunder, as each may
be amended from time to time.

SECTION 7.
AMENDMENT, TERMINATION AND DURATION
7.1 Amendment, Suspension or Termination
The Board or the Committee, each in its sole discretion, may amend or terminate
the Plan, or any part thereof, at any time and for any reason. The amendment,
suspension or termination of the Plan shall not, without the consent of the
Participant, alter or impair any rights or obligations under any Target Award
theretofore granted to such Participant. No award may be granted during any
period of suspension or after termination of the Plan.
