SECTION 3

POSITION AND DUTIES

The Executive will serve as Executive Vice-President — Acquisitions of the Company during the
Employment Period. The title of Executive can be reasonably adjusted by the Company. The
Executive will render management services to the Company as reasonably determined by the Board and
Chief Executive Officer of the Company (the “CEO”). The Company shall provide the
Executive with necessary authority and resources to discharge the Executive’s responsibilities
under laws and regulations applicable to the Company and Executive.

The Executive will report directly to the CEO. The Executive shall not be required to take
direction from or report to any other person unless otherwise directed by the Board or the CEO.
The Executive will devote the Executive’s best efforts and full business time to the performance of

SECTION 4

PLACE OF PERFORMANCE

During the Employment Period, the Executive’s primary place of employment and work location
will be Scottsdale, Arizona, except for reasonable travel on Company business and as otherwise
reasonably requested by the CEO.

SECTION 5

COMPENSATION

Base Salary

During the Employment Period, the Company will pay to the Executive an annual base salary (the
“Base Salary”), which initially will be Two Hundred Seventy-Five Thousand Dollars
($275,000.00). The Base Salary will be reviewed by the Compensation Committee of the Board (the
“Compensation Committee”) no less frequently than annually and may be increased or
decreased at the sole discretion of the Compensation Committee. If the Executive’s Base Salary is
increased, the increased amount will be the Base Salary for the remainder of the Employment Period.
The Base Salary will be payable semi-monthly or in such other installments as will be consistent
with the Company’s payroll procedures in effect from time to time.

Bonus

During the Employment Period, the Executive will be eligible to earn an annual performance
bonus in an amount determined at the sole discretion of the Compensation Committee for each year.
It is the intention of the parties hereto that the Company shall establish bonus parameters for
the Executive with respect to each fiscal year of the Employment Period. Executive acknowledges and
agrees that his annual bonus is not guaranteed at any level, rather it is to be determined solely
by the Compensation Committee, in its sole discretion. The Compensation Committee will establish
the performance goals and objectives on which the annual bonus will be based. The Executive’s
initial full year annual target bonus will be up to 100% of the Base Salary (pro-rata for the time
worked in the fiscal year). In the event that a target bonus is not established with respect to
any subsequent fiscal year, the Executive’s target bonus shall be deemed to be the target bonus
established under this Agreement for the immediately preceding year.

Equity Compensation – Restricted Stock Units

Subject to the approval of the Board of Directors and the conditions and restrictions herein,
within sixty (60) days after the Executive relocates to the Phoenix, Arizona metropolitan area, the
Company will grant to the Executive 40,000 restricted stock units (the “Restricted Stock
Units”). The date of such grant shall be referred to herein as the “Grant Date.”
Subject to the Executive’s continued employment by the Company through each vesting date, the
Restricted Stock Units will vest and convert to shares of the Company’s Common Stock in equal
annual installments of 33-1/3% each, on the first, second and third anniversaries of the Grant
Date. The Restricted Stock Units shall be granted pursuant to, and will be subject to the terms
and conditions of, the NNN Healthcare/Office REIT, Inc. 2006 Incentive Plan (the “Plan”)
and the Company’s standard Restricted Stock Unit Agreement. If there is any inconsistency or
ambiguity among this Agreement, the Plan or the Restricted Stock Unit Agreement, the Plan shall
prevail.

Participation – Equity Interest

The Company is currently contemplating a “Follow-On Offering” (the “Follow-On
Offering”). In the event the Company proceeds with the Follow-On Offering, is ultimately
successful in raising funds and for so long as the Executive remains with the Company and performs
to the satisfaction of the Company, the Executive shall be entitled to receive a direct or indirect
equity interest in the Company (which equity interest may be held by a limited liability company
managed by the Company in which the Executive is a member) (the “Equity Interest”)
entitling the Executive to distributions or dividends upon the achievement of certain returns or
benchmarks by the Company related to the value of the assets acquired by the Company with the
proceeds of the Follow-On Offering.

Subject to Board approval of the establishment of the Equity Interest program, the terms of
the Equity Interest, the documents that convey the Equity Interest and the receipt of all
regulatory approvals necessary for the Company to conduct the Follow-On Offering in all fifty (50)
states, Puerto Rico and the District of Columbia, the Company shall issue up to a possible .25%
interest to the Executive in the appreciation (the “Appreciation”) that the Company
realizes from properties and other interests acquired using proceeds from the Follow-on Offering
after the distribution by the Company to its stockholders of the gross purchase price for all of
the Company’s issued shares (as reduced by any shares redeemed pursuant to the Company’s stock
redemption plan) and a cumulative 8% per annum return on the gross purchase price for all such
shares, as will be described in the documents that evidence the Equity Interest; provided that the
Executive acknowledges the terms of the Equity Interest have not been finally determined by the
Board and that changes to the terms of the Equity Interest may be required by the Board in order
for the Follow-On Offering to be declared effective by each of the regulatory authorities with
jurisdiction over the Follow-On Offering and that, as a result of such changes, the right to
receive the Equity Interest is subject to modification or elimination.

Notwithstanding any other provisions herein to the contrary, the Company’s obligation to issue
and the Executive’s right to receive the Equity Interest is subject to the following:

(i) Notwithstanding any other provisions herein to the contrary, the Executive acknowledges
and agrees that: (i) the Executive has not received and the Company has not provided any assurance
or representation of any kind relating to the Equity Interest; (ii) the Executive does not have any
expectation of any minimum level of a direct or indirect equity interest in the Company or a
subordinated participation interest in the Company; (iii) neither the Company nor any director,
officer, shareholder, partner, member, employee, trustee, representative or agent of the Company
shall have any liability or responsibility to the Executive for any act or omission performed or
failed to be performed by it, or for any losses, claims, costs, damages, or liabilities arising
from any such act or omission relating to the acquisition, management, operation, or disposition of
the Company’s assets; (iv) the Company shall have full power, authority, discretion and control
with respect to its assets; and (v) any rights of the Executive to the Equity Interest, if any, are
personal to the Executive and, notwithstanding any other provisions herein to the contrary, may not
be assigned by the Executive except to the extent permitted by the documents that evidence such
interest. The foregoing provisions are of material importance to the Company. The Executive
acknowledges and agrees that the Company has agreed to the grant of the Equity Interest (subject to
the provisions herein), if any, in reliance of the Executive’s agreement to the foregoing
provisions.

(ii) Notwithstanding any other provisions herein to the contrary, if this Agreement is
terminated by the Company for Cause, then the Equity Interest shall be forfeited.

(iii) Notwithstanding any other provision herein to the contrary, if the Executive terminates
this Agreement for any reason, other than for Good Reason, then the Equity Interest shall be
forfeited.

(iv) Notwithstanding any other provisions herein to the contrary, payment of the Equity
Interest shall be subject to and conditioned upon the Executive’s compliance with all applicable
laws, rules and regulations and the Executive’s compliance with the terms of this Agreement.

(v) Notwithstanding any other provisions herein to the contrary, retention of the Equity
Interest shall be subject to and conditioned upon the Executive’s continued employment with the
Company in accordance with this Agreement.

(vi) Notwithstanding any other provisions herein to the contrary, retention of the Equity
Interest shall be subject to and conditioned upon the Executive’s compliance with the terms and
conditions of the Non-Compete Agreement (as defined herein).

During the Employment Period, the Executive will be entitled to all employee benefits and
perquisites made available to senior executives of the Company, including, without limitation,
group medical, dental, vision, life insurance, long-term disability insurance, retirement, pension,

Executive is eligible for participation in any such plans. The Company shall pay 100% of the
premium cost of the Company’s health insurance coverage provided to the Executive (and the
Executive’s dependants, if applicable) by the Company from time to time. Nothing contained in this
Agreement will prevent the Company from terminating plans, changing carriers or effecting
modifications in employee benefits coverage for the Executive as long as such modifications affect
all similarly situated senior executives of the Company.

During the Employment Period, the Executive will be entitled to all public holidays observed
by the Company and vacation days in accordance with the applicable vacation policies for senior
executives of the Company, which vacation days will be taken at a reasonable time or times. The

time is capped at a maximum of four (4) weeks.

Directors and Officers Insurance and Indemnification

The Company shall maintain insurance to insure the Executive against claims arising out of an
alleged wrongful act by the Executive while acting in good faith as an officer of the Company or

Executive while acting in good faith as an officer or employee of the Company, or of its
subsidiaries, to the fullest extent permitted under applicable law.

Withholding Taxes and Other Deductions

To the extent required by law, the Company will withhold from any payments due to the
Executive under this Agreement any applicable federal, state or local taxes and such other
deductions as are prescribed by law or authorized by the Executive. With respect to any taxable

Compensation Committee, elect that any withholding requirement be satisfied, in whole or in part,
by withholding from the Restricted Stock Units shares of Common Stock having a Fair Market Value
(as defined in the Plan) on the date of withholding equal to the minimum amount (and not any

Entire Agreement

This Agreement constitutes the entire agreement between the parties respecting the employment
of the Executive, there being no representations, warranties or commitments between the parties
except as set forth herein.

Counterparts

This Agreement may be executed in two or more counterparts, each of which will be an original

Provisions Regarding Code Section 409A

This Agreement shall be interpreted and administered in a manner so that any amount or benefit
payable hereunder shall be paid or provided in a manner that is either exempt from or compliant
with the requirements Section 409A of the Code and applicable Internal Revenue Service guidance and
Treasury Regulations issued thereunder (and any applicable transition relief under Section 409A of
the Code).

Notwithstanding anything in this Agreement to the contrary, to the extent that any amount or
benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A of
the Code would otherwise be payable or distributable hereunder by reason of the Executive’s
termination of employment, such amount or benefit will not be payable or distributable to the
Executive by reason of such circumstance unless (i) the circumstances giving rise to such
termination of employment meet any description or definition of “separation from service” in
Section 409A of the Code and applicable regulations (without giving effect to any elective
provisions that may be available under such definitions), or (ii) the payment or distribution of
such amount or benefit would be exempt from the application of Section 409A of the Code by reason
of the short-term deferral exemption or otherwise. If this provision prevents the payment or
distribution of any amount or benefit, such payment or distribution shall be made on the date, if
any, on which an event occurs that constitutes a Section 409A-compliant “separation from service,”
or such later date as may be required by the following paragraph.

If any amount or benefit that would constitute non-exempt “deferred compensation” for purposes
of Section 409A of the Code would otherwise be payable or distributable under this Agreement by
reason of the Executive’s separation from service during a period in which the Executive is a
“specified employee” (as defined in Section 409A of the Code and applicable regulations), then
payment or commencement of such non-exempt amounts or benefits shall be delayed until the earlier
of (i) thirty (30) days following Executive’s death, or (ii) the first day of the seventh month
following the Executive’s separation from service.

Whenever in this Agreement the provision of payment or benefit is conditioned on the
Executive’s execution and non-revocation of a general release of claims, such release, must be
executed, and all revocation periods shall have expired, within 60 days after the Date of
Termination, but the Company may elect to commence payment at any time during such 60-day period.

If the Executive (or the Executive’s spouse or eligible dependents) is entitled to be paid or
reimbursed for any taxable expenses under this Agreement, including, but not limited to, those
expenses provided in Sections 5 and 6, and such payments or reimbursements are includible
in the Executive’s federal gross taxable income, the amount of such expenses reimbursable in any
one calendar year shall not affect the amount reimbursable in any other calendar year, and the
reimbursement of an eligible expense must be made no later than December 31 of the year after the
year in which the expense was incurred. No right of the Executive to reimbursement of expenses
under this Agreement, including, but not limited to, those provided in Sections 5 and 6,
shall be subject to liquidation or exchange for another benefit.

This EMPLOYMENT AGREEMENT (this “Agreement”) is entered into and effective as of the

(the “Company”), and Kellie S. Pruitt (the “Executive”).

WHEREAS, the parties had previously entered into that initial letter agreement dated January

employment arrangement of the Executive with the Company;

WHEREAS, the parties hereto wish to supersede and replace the Initial Agreement (except as
specified herein) and enter into the arrangements set forth herein with respect to the terms and
conditions of the Executive’s continued employment with the Company from and after the “Effective
Date” (as defined herein);

NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth herein and
other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

SECTION 1

EMPLOYMENT AGREEMENT

This Agreement shall supersede and replace the Initial Agreement, which shall be of no further
force and effect as of July 1, 2009. Subject to the terms and conditions set forth in this
Agreement, the Company agrees to employ the Executive, and the Executive agrees to be employed by
the Company, for the Employment Period defined herein. Terms used herein with initial
capitalization are defined in Section 10.

SECTION 2

TERM

The term of the Executive’s employment hereunder in the position referenced under
Section 3 will begin as of July 1, 2009 (the “Effective Date”) and will conclude on
June 30, 2011 (the “Original Term”) subject to earlier termination as provided in
Section 7 herein. At the sole discretion of the Company, the Agreement may be extended for
an additional one (1) year term (the “Renewal Term”), by Company providing the Executive
with written notice of such extension at least one-hundred eighty (180) days prior to the Extension
Date.

The Original Term and any Renewal Term, in their full duration, are herein referred to as the
“Employment Terms.” The period of the Executive’s employment under this Agreement
consisting of the Original Term and any Renewal Term, except as may be terminated early pursuant to
Section 7, is herein referred to as the “Employment Period.”

SECTION 3

POSITION AND DUTIES

The Executive will serve as Chief Accounting Officer, Treasurer and Assistant Secretary of the
Company during the Employment Period. The title of Executive can be reasonably adjusted by the
Company. The Executive will render management services to the Company as reasonably determined by
the Board and Chief Executive Officer of the Company (the “CEO”). The Company shall
provide the Executive with necessary authority and resources to discharge the Executive’s
responsibilities under laws and regulations applicable to the Company and Executive.

The Executive will report directly to the CEO. The Executive shall not be required to take
direction from or report to any other person unless otherwise directed by the Board or the CEO.
The Executive will devote the Executive’s best efforts and full business time to the performance of
the Executive’s duties hereunder and the advancement of the business and affairs of the Company

Agreement and subject to pre-approval of the CEO, pursue other limited outside interests, including
but not limited to, devoting time to (A) serving on corporate, civic or charitable boards or
committees, (B) delivering lectures, fulfilling speaking engagements or teaching at educational
institutions and (C) managing the Executive’s personal investments, so long as such activities do
not interfere with the full time performance of Executive’s responsibilities as Chief Accounting
Officer, Treasurer and Assistant Secretary of the Company in accordance with this Agreement.

SECTION 4

PLACE OF PERFORMANCE

During the Employment Period, the Executive’s primary place of employment and work location
will be Scottsdale, Arizona, except for reasonable travel on Company business and as otherwise
reasonably requested by the CEO.

SECTION 5

COMPENSATION

Base Salary

During the Employment Period, the Company will pay to the Executive an annual base salary (the
“Base Salary”), which initially will be One Hundred Eighty Thousand Dollars ($180,000.00).
The Base Salary will be reviewed by the Compensation Committee of the Board (the “Compensation
Committee”) no less frequently than annually and may be increased or decreased at the sole
discretion of the Compensation Committee. If the Executive’s Base Salary is increased, the
increased amount will be the Base Salary for the remainder of the Employment Period. The Base
Salary will be payable semi-monthly or in such other installments as will be consistent with the
Company’s payroll procedures in effect from time to time.

Bonus

During the Employment Period, the Executive will be eligible to earn an annual performance
bonus in an amount determined at the sole discretion of the Compensation Committee for each year.
It is the intention of the parties hereto that the Company shall establish bonus parameters for
the Executive with respect to each fiscal year of the Employment Period. Executive acknowledges and
agrees that her annual bonus is not guaranteed at any level, rather it is to be determined solely
by the Compensation Committee, in its sole discretion. The Compensation Committee will establish
the performance goals and objectives on which the annual bonus will be based. The Executive’s
initial full year annual target bonus will be up to 60% of the Base Salary (pro-rata for the time
worked in the fiscal year). In the event that a target bonus is not established with respect to
any subsequent fiscal year, the Executive’s target bonus shall be deemed to be the target bonus
established under this Agreement for the immediately preceding year.

Equity Compensation – Restricted Stock Units

Subject to the approval of the Board of Directors and the conditions and restrictions herein,
within thirty (30) days after the Effective Date, the Company will grant to the Executive 25,000
restricted stock units (the “Restricted Stock Units”). Subject to the Executive’s
continued employment by the Company through each vesting date, the Restricted Stock Units will vest
and convert to shares of the Company’s Common Stock in equal annual installments of 33-1/3% each,
on the first, second and third anniversaries of the Effective Date. The Restricted Stock Units
shall be granted pursuant to, and will be subject to the terms and conditions of, the NNN
Healthcare/Office REIT, Inc. 2006 Incentive Plan (the “Plan”) and the Company’s standard
Restricted Stock Unit Agreement. If there is any inconsistency or ambiguity among this Agreement,
the Plan or the Restricted Stock Unit Agreement, the Plan shall prevail.

Participation – Equity Interest

The Company is currently contemplating a “Follow-On Offering” (the “Follow-On
Offering”). In the event the Company proceeds with the Follow-On Offering, is ultimately
successful in raising funds and for so long as the Executive remains with the Company and performs
to the satisfaction of the Company, the Executive shall be entitled to receive a direct or indirect
equity interest in the Company (which equity interest may be held by a limited liability company
managed by the Company in which the Executive is a member) (the “Equity Interest”)
entitling the Executive to distributions or dividends upon the achievement of certain returns or
benchmarks by the Company related to the value of the assets acquired by the Company with the
proceeds of the Follow-On Offering.

Subject to Board approval of the establishment of the Equity Interest program, the terms of
the Equity Interest, the documents that convey the Equity Interest and the receipt of all
regulatory approvals necessary for the Company to conduct the Follow-On Offering in all fifty (50)
states, Puerto Rico and the District of Columbia, the Company shall issue up to a possible .25%
interest to the Executive in the appreciation (the “Appreciation”) that the Company
realizes from properties and other interests acquired using proceeds from the Follow-on Offering
after the distribution by the Company to its stockholders of the gross purchase price for all of
the Company’s issued shares (as reduced by any shares redeemed pursuant to the Company’s stock
redemption plan) and a cumulative 8% per annum return on the gross purchase price for all such
shares, as will be described in the documents that evidence the Equity Interest; provided that the
Executive acknowledges the terms of the Equity Interest have not been finally determined by the
Board and that changes to the terms of the Equity Interest may be required by the Board in order
for the Follow-On Offering to be declared effective by each of the regulatory authorities with
jurisdiction over the Follow-On Offering and that, as a result of such changes, the right to
receive the Equity Interest is subject to modification or elimination.

Notwithstanding any other provisions herein to the contrary, the Company’s obligation to issue
and the Executive’s right to receive the Equity Interest is subject to the following:

(i) Notwithstanding any other provisions herein to the contrary, the Executive acknowledges
and agrees that: (i) the Executive has not received and the Company has not provided any assurance
or representation of any kind relating to the Equity Interest; (ii) the Executive does not have any
expectation of any minimum level of a direct or indirect equity interest in the Company or a
subordinated participation interest in the Company; (iii) neither the Company nor any director,
officer, shareholder, partner, member, employee, trustee, representative or agent of the Company
shall have any liability or responsibility to the Executive for any act or omission performed or
failed to be performed by it, or for any losses, claims, costs, damages, or liabilities arising
from any such act or omission relating to the acquisition, management, operation, or disposition of
the Company’s assets; (iv) the Company shall have full power, authority, discretion and control
with respect to its assets; and (v) any rights of the Executive to the Equity Interest, if any, are
personal to the Executive and, notwithstanding any other provisions herein to the contrary, may not
be assigned by the Executive except to the extent permitted by the documents that evidence such
interest. The foregoing provisions are of material importance to the Company. The Executive
acknowledges and agrees that the Company has agreed to the grant of the Equity Interest (subject to
the provisions herein), if any, in reliance of the Executive’s agreement to the foregoing
provisions.

(ii) Notwithstanding any other provisions herein to the contrary, if this Agreement is
terminated by the Company for Cause, then the Equity Interest shall be forfeited.

(iii) Notwithstanding any other provision herein to the contrary, if the Executive terminates
this Agreement for any reason, other than for Good Reason, then the Equity Interest shall be
forfeited.

(iv) Notwithstanding any other provisions herein to the contrary, payment of the Equity
Interest shall be subject to and conditioned upon the Executive’s compliance with all applicable
laws, rules and regulations and the Executive’s compliance with the terms of this Agreement.

(v) Notwithstanding any other provisions herein to the contrary, retention of the Equity
Interest shall be subject to and conditioned upon the Executive’s continued employment with the
Company in accordance with this Agreement.

(vi) Notwithstanding any other provisions herein to the contrary, retention of the Equity
Interest shall be subject to and conditioned upon the Executive’s compliance with the terms and
conditions of the Non-Compete Agreement (as defined herein).

Benefits

During the Employment Period, the Executive will be entitled to all employee benefits and
perquisites made available to senior executives of the Company, including, without limitation,
group medical, dental, vision, life insurance, long-term disability insurance, retirement, pension,
401(k) savings plans and/or prescription drug plan coverage, subject to the condition that the
Executive is eligible for participation in any such plans. The Company shall pay 100% of the
premium cost of the Company’s health insurance coverage provided to the Executive (and the
Executive’s dependants, if applicable) by the Company from time to time. Nothing contained in this
Agreement will prevent the Company from terminating plans, changing carriers or effecting
modifications in employee benefits coverage for the Executive as long as such modifications affect
all similarly situated senior executives of the Company.

Vacation; Holidays

During the Employment Period, the Executive will be entitled to all public holidays observed
by the Company and vacation days in accordance with the applicable vacation policies for senior
executives of the Company, which vacation days will be taken at a reasonable time or times. The
Executive will initially be entitled to four (4) weeks vacation per year, and accrual of vacation
time is capped at a maximum of four (4) weeks.

Directors and Officers Insurance and Indemnification

The Company shall maintain insurance to insure the Executive against claims arising out of an
alleged wrongful act by the Executive while acting in good faith as an officer of the Company or
one of its subsidiaries. The Company shall further indemnify and exculpate the Executive from
money damages incurred as a result of claims arising out of an alleged wrongful act by the
Executive while acting in good faith as an officer or employee of the Company, or of its
subsidiaries, to the fullest extent permitted under applicable law.

Withholding Taxes and Other Deductions

To the extent required by law, the Company will withhold from any payments due to the
Executive under this Agreement any applicable federal, state or local taxes and such other
deductions as are prescribed by law or authorized by the Executive. With respect to any taxable
event related to the Restricted Stock Units, the Executive may, subject to prior approval by the
Compensation Committee, elect that any withholding requirement be satisfied, in whole or in part,
by withholding from the Restricted Stock Units shares of Common Stock having a Fair Market Value
(as defined in the Plan) on the date of withholding equal to the minimum amount (and not any
greater amount) required to be withheld for tax purposes, all in accordance with such procedures as
the Compensation Committee establishes.

Entire Agreement

This Agreement constitutes the entire agreement between the parties respecting the employment
of the Executive, there being no representations, warranties or commitments between the parties

Counterparts

This Agreement may be executed in two or more counterparts, each of which will be an original

Provisions Regarding Code Section 409A

This Agreement shall be interpreted and administered in a manner so that any amount or benefit
payable hereunder shall be paid or provided in a manner that is either exempt from or compliant
with the requirements Section 409A of the Code and applicable Internal Revenue Service guidance and
Treasury Regulations issued thereunder (and any applicable transition relief under Section 409A of
the Code).

Notwithstanding anything in this Agreement to the contrary, to the extent that any amount or
benefit that would constitute non-exempt “deferred compensation” for purposes of Section 409A of
the Code would otherwise be payable or distributable hereunder by reason of the Executive’s
termination of employment, such amount or benefit will not be payable or distributable to the
Executive by reason of such circumstance unless (i) the circumstances giving rise to such
termination of employment meet any description or definition of “separation from service” in
Section 409A of the Code and applicable regulations (without giving effect to any elective
provisions that may be available under such definitions), or (ii) the payment or distribution of
such amount or benefit would be exempt from the application of Section 409A of the Code by reason
of the short-term deferral exemption or otherwise. If this provision prevents the payment or
distribution of any amount or benefit, such payment or distribution shall be made on the date, if
any, on which an event occurs that constitutes a Section 409A-compliant “separation from service,”
or such later date as may be required by the following paragraph.

If any amount or benefit that would constitute non-exempt “deferred compensation” for purposes
of Section 409A of the Code would otherwise be payable or distributable under this Agreement by
reason of the Executive’s separation from service during a period in which the Executive is a
“specified employee” (as defined in Section 409A of the Code and applicable regulations), then
payment or commencement of such non-exempt amounts or benefits shall be delayed until the earlier
of (i) thirty (30) days following Executive’s death, or (ii) the first day of the seventh month
following the Executive’s separation from service.

Whenever in this Agreement the provision of payment or benefit is conditioned on the
Executive’s execution and non-revocation of a general release of claims, such release, must be
executed, and all revocation periods shall have expired, within 60 days after the Date of
Termination, but the Company may elect to commence payment at any time during such 60-day period.

If the Executive (or the Executive’s spouse or eligible dependents) is entitled to be paid or
reimbursed for any taxable expenses under this Agreement, including, but not limited to, those
expenses provided in Sections 5 and 6, and such payments or reimbursements are includible
in the Executive’s federal gross taxable income, the amount of such expenses reimbursable in any
one calendar year shall not affect the amount reimbursable in any other calendar year, and the
reimbursement of an eligible expense must be made no later than December 31 of the year after the
year in which the expense was incurred. No right of the Executive to reimbursement of expenses
under this Agreement, including, but not limited to, those provided in Sections 5 and 6,
shall be subject to liquidation or exchange for another benefit.
