of your employment with the Company.

1)
Term of Employment. Your employment under this Letter Agreement is effective as
of January 2, 2012 (the "Effective Date") and, subject to termination as
provided in Sections 7 or 8, will end on the first anniversary of the Effective
Date; provided that on each anniversary of the Effective Date, the term of your
employment will automatically be extended by an additional year unless the
Company or you give the other party written notice, at least 30 days prior to
the applicable anniversary of the Effective Date, that you do not or it does not
want the term to be so extended. Such employment period, as may be so extended,
will hereinafter be referred to as the "Term".

2)
Title and Duties.

a)
Position. During the Term, you will be employed by the Company as an Executive
Vice President. You will have such duties and responsibilities and power and
authority as assigned to you by the Board, the Chief Executive Officer (the
“CEO”) or the President and Chief Operating Officer of the Company.

b)
Exclusive Duties. During your employment by the Company, you will devote
substantially all your entire working time, attention and energies to the
business of the Company and its Affiliates (as defined below) and will not,
without the prior written consent of the Board undertake any other business
activities. Without limiting the generality of the foregoing, you will not take
any actions of the kind described in Section 10.

3)
Base Salary. During the Term, the Company will pay you a minimum base salary at
the annual rate of $450,000, payable in accordance with the Company's regular
payroll practices. The Human Resources Committee of the Board (the "Committee")
will review your base salary annually and may, in its sole discretion, increase
your base salary based on your performance and the Company's performance. Such
base salary, as may be increased, will hereinafter be referred to as your "Base

4)

performance-based restricted stock units at “target” performance level on the
terms and subject to the conditions of the 2011 Restricted Stock Units Award
Document attached to this Agreement as Exhibit A.

b)
Additional Grants. During the Term, you will be eligible to receive (i) a grant

Committee and shall be consistent with the terms of the grants for such
performance periods made to the Company’s other executive officers generally.
The size and terms of any equity grants for subsequent performance periods
during the Term that would vest in any fiscal year after 2017 will be determined
by the Committee based on your performance and the Company’s performance, as
well as terms of the equity compensation plan under which the equity grant is
granted. In the event for any fiscal year during the Term for which you are
eligible to receive grants pursuant to the first sentence of this Section 5(b)

restricted stock units to the Company’s other executive officers generally, the

both of the 2015 Grant and the 2016 Grant, or (ii) multiplied times 15,000 in
the event the Change in Control is effective after your receipt of the 2015
Grant but prior to your receipt of the 2016 Grant. The payment in the proceeding
sentence shall be in lieu of the 2015 Grant and/or the 2016 Grant if the change
in Control occurs prior to your receipt of such grants. Anything herein to the
contrary notwithstanding, in the event of a payment provided in this subsection
