occurred; provided, that if the Executive commences employment with another
employer, whether as an employee or as a consultant, prior to the Ending Date
(for purposes of this Paragraph 10, the “Other Employment”), then such payments
of the Base Salary shall be reduced from time to time by the aggregate amount of

from the Other Employment for services performed by him during the period from
the commencement of the Other Employment through the Ending Date;

subparagraph (e) the Ending Date shall be two (2) years after the effective date

paid to the Executive in a lump sum not later than thirty (30) days after the
effective date of such termination.”

3. Effective immediately, Paragraph 10(i) of the Restated Employment Agreement
hereby is amended in its entirety so as to read as follows:

“(i) Notice of Other Employment and of Benefits. The Executive promptly shall
notify the Companies in writing of (i) his acceptance of the Other Employment

generally.”

5. Paragraph 10(m) of the Restated Employment Agreement hereby is amended in its
entirety so as to read as follows:

“(m) Section 409A; Time and Form of Payments and Benefits. The parties intend

employment pursuant to this Paragraph 10 shall be eligible for certain
regulatory

 

3

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

exceptions to the limitations imposed on deferred compensation by Section 409A
of the Code or shall comply with the requirements of Section 409A of the Code.
The purpose of this subparagraph (m) is solely to enable this agreement to
comply with, or be eligible for one or more exceptions from, the requirements of
Section 409A of the Code.

 

  (i) Time and Form of Payment. Each of the following amounts payable to the
Executive under this agreement shall constitute a separate payment for purposes
of Section 409A of the Code:

 

  (1) Each pay period installment of Base Salary payable to the Executive
pursuant to subparagraphs 10(d)(i) or 10(f)(iii) (each such installment, a
“Salary Continuation Payment”).

 

  •  

Each Salary Continuation Payment shall be paid in accordance with the payroll
payment schedule of the Companies in effect on the effective date of the
Executive’s termination of employment with the Companies.

 

  (2) Any annual incentive bonus payable to the Executive pursuant to
subparagraph 10(g)(iii) (‘‘Full Termination Year Bonus”).

 

  •  

Any Full Termination Year Bonus shall be paid during the calendar year
immediately following the calendar year in which the effective date of the
Executive’s termination of employment with the Companies occurs, such payment to
be made on the date when such bonuses are normally paid by the Companies (but in
no event after the end of the calendar year immediately following the calendar
year in which the Executive’s termination of employment with the Companies is
effective).

 

  (3) Any pro rata portion of the Executive’s annual incentive bonus for the
calendar year of the Executive’s termination of employment pursuant to
subparagraphs 10(a)(ii) or 10(b)(ii) (“Pro-Rated Termination Year Bonus”).

 

  •  

Any Pro-Rated Termination Year Bonus shall be paid during the calendar year
immediately following the calendar year in which the effective date of the
Executive’s termination of employment with the Companies occurs, such payment to
be made on the date when such bonuses are normally paid by the Companies (but in
no event after the end of the calendar year immediately following the calendar
year in which the Executive’s termination of employment with the Companies is
effective).

 

4

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

  (4) Any Base Salary amount payable pursuant to subparagraphs 10(e)(i) or
10(f)(iii) (“Lump Sum Salary”).

 

  •  

Any Lump Sum Salary shall be paid not later than thirty (30) days following the
effective date of the Executive’s termination of employment with the Companies.

 

  (5) Any amounts payable in two (2) installments as a percentage of the
Executive’s Base Salary pursuant to subparagraphs 10(d)(ii) or 10(f)(iii)
(“Percentage Base Amount”),

 

 

•

 

One-half ( 1/2) of any Percentage Base Amount shall be paid not later than
thirty (30) days after the effective date of the Executive’s termination of
employment with the Companies, and the other one-half ( 1/2) of any Percentage
Base Amount shall be paid on the date that is one year after the effective date
of the Executive’s termination of employment with the Companies.

 

  (6) Any amounts payable in a lump sum as a percentage of the Executive’s Base
Salary pursuant to subparagraphs 10(e)(ii) or 10(f)(iii) (“Lump Sum Percentage
Base Amount”).

 

  •  

Any Lump Sum Percentage Base Amount shall be paid not later than thirty
(30) days after the effective date of the Executive’s termination of employment
with the Companies.

 

  (7) Any amounts payable to the Executive pursuant to subparagraph 10(1) as an
“Additional Payment” and any “Gross-Up Payment” (the “Preliminary Gross-Up
Payment”).

 

5

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

  •  

Any Preliminary Gross-Up Payment shall be paid not later than thirty (30) days
following the effective date of the Executive’s termination of employment with
the Companies.

 

  (8) Any amounts payable to the Executive pursuant to subparagraph 10(1) as a
“further Gross-Up Payment” (the “Adjustment Gross-Up Payment”).

 

  •  

Any Adjustment Gross-Up Payment shall be paid during the calendar year
immediately following the calendar year in which the effective date of the
Executive’s termination of employment with the Companies occurs.

 

  (ii) Continuation of Benefits. Subparagraphs 10(b)(iv), 10(d)(iv), 10(e), and
10(f) provide for continued participation by the Executive in designated health
and welfare benefit programs of the Companies for a specified period. The
parties intend that any in-kind benefits or reimbursement of expenses incurred
by the Executive with respect to the continuation of benefits satisfy the
requirements for a fixed schedule of payments with respect to such benefits or
payments as required by Treas. Reg. § 1.409A-3(i)(l)(iv). To the extent such
continued participation by the Executive involves any payment for continued
coverage by the Executive and reimbursement to the Executive, the amount of any
such reimbursement shall be paid to the Executive (or his beneficiary) by
December 31 of the calendar year immediately following the year in which the
Executive pays the actual cost of continued coverage. The amount of expenses
eligible for reimbursement, or in-kind benefits provided, during a calendar year
may not affect the expenses eligible for reimbursement, or in-kind benefits to
be provided, in any other taxable year. Further, the right to reimbursement or
in-kind benefits is not subject to liquidation or exchange for another benefit.

 

6

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

  (iii) Six-Month Delay in Payment. Notwithstanding anything contained in this
agreement to the contrary, if the Executive is deemed by the Companies at the
time of the Executive’s “separation from service” with the Companies to be a
“specified employee,” any compensation or benefits to which the Executive
becomes entitled under this agreement in connection with such separation shall
not be paid or commence until the date which is the first business day following
the six month period after the Executive’s separation from service (or if
earlier, the Executive’s death). Such delay in payment shall only be effected
with respect to each separate payment or benefit to the extent required to avoid
adverse tax treatment to the Executive, including (without limitation) the
additional 20% tax for which the Executive would otherwise be liable under
Section 409A(a)(l)(B) of the Code in the absence of such delay in payment. Upon
the expiration of the delay period, any compensation or benefits which would
have otherwise been paid during the delay period (whether in a single sum or in
installments) in the absence of this subparagraph (iii) shall be paid to the
Executive or his beneficiary in a lump sum payment.

 

  (iv) Key Definitions. For purposes of Paragraph 10 of this agreement, the
terms “separation from service” and “specified employee,” and, solely with
respect to subparagraph 10(b)(iv), the term “disability,” shall have the
meanings ascribed to such terms pursuant to Section 409A of the Code and the
related treasury regulations and other applicable guidance.”

6. As amended by this First Amendment, the Restated Employment Agreement shall
remain in full force and effect according to its terms.
