UNSECURED PROMISSORY NOTE (this “Note”)

$ 7,500,000

January 22, 2007 (the “Note Date”)

FOR VALUE RECEIVED, NNN Healthcare/Office REIT Holdings, L.P., a Delaware limited partnership
(“Borrower”), unconditionally promises to pay NNN Realty Advisors, Inc., a Delaware corporation
(“Lender”), in the manner and at the place hereinafter provided, the principal amount of Seven
Million Five Hundred Thousand Dollars ($7,500,000).

Borrower also promises to pay interest on the unpaid principal amount hereof from the Note
Date until paid in full at a rate per annum equal to the Interest Rate (capitalized terms used
herein and not otherwise defined herein shall have the meanings provided in Schedule A
attached hereto), provided that any principal amount not paid when due and, to the extent permitted
by applicable law, any interest not paid when due, in each case whether at stated maturity,
declaration, acceleration, demand or otherwise (both before as well as after judgment), shall bear
interest payable upon demand at a rate per annum equal to the Default Interest Rate. Interest on
this Note shall be payable in arrears on the first day of each month beginning on the Commencement
Date, each date on which an installment of principal is due and payable hereunder, upon any
prepayment of this Note (to the extent accrued on the amount being prepaid) and at maturity. All
computations of interest shall be made by Lender on the basis of a 365-day year, for the actual
number of days elapsed in the relevant period (including the first day but excluding the last day).
In no event shall the interest rate payable on this Note exceed the maximum rate of interest
permitted to be charged under applicable law.

1. Maturity Date. The outstanding principal amount of the Note, and any accrued but
unpaid interest thereon, shall be automatically due and payable on the Maturity Date.

2. Payments. All payments of principal and interest in respect of this Note shall be
made in lawful money of the United States of America in same day funds at the office of Lender
located at 1551 N. Tustin Avenue, Suite 200, Santa Ana, California 92705, or at such other place as
Lender may direct. Whenever any payment on this Note is stated to be due on a day that is not a
Business Day (as defined herein), such payment shall instead be made on the next Business Day and
such extension of time shall be included in the computation of interest payable on this Note. Each
payment made hereunder shall be credited first to interest then due and the remainder of such
payment shall be credited to principal, and interest shall thereupon cease to accrue upon the
principal so credited. Each of Lender and any subsequent holder of this Note agrees, by its
acceptance hereof, that before disposing of this Note or any part hereof the Lender and any
subsequent holder of this Note will mutually agree on the amount of all principal payments
previously made hereunder and of the date to which interest hereon has been paid; provided,
however, that the failure to make a notation of any payment made on this Note shall not
limit or otherwise affect the obligation of Borrower hereunder with respect to payments of
principal or interest on this Note. “Business Day” means any day other than a Saturday, Sunday or
legal holiday under the laws of the State of California or any other day on which banking
institutions located in such state are authorized or required by law or other governmental action
to close.

3. Prepayments. Borrower shall have the right at any time and from time to time on or
prior to the Maturity Date to prepay the principal of this Note in whole or in part, without
premium or penalty. Any prepayment hereunder shall be accompanied by the payment of accrued
interest on the principal amount of the Note being prepaid to the date of prepayment.

4. Covenants. Borrower covenants and agrees that until this Note is paid in full it
will:

(a) promptly provide to Lender financial and operational information with respect to
Borrower or any of its subsidiaries as Lender may reasonably request;

(b) promptly after the occurrence of an Event of Default (as defined herein) or an
event, act or condition that, with notice or lapse of time or both, would constitute an
Event of Default, provide Lender with a certificate of the chief executive officer, chief
financial officer or general partner(s) of Borrower specifying the nature thereof and
Borrower’s proposed response thereto; and

(c) not merge or consolidate with any other Person (as defined herein), or sell, lease
or otherwise dispose of all or any substantial part of its property or assets to any other
Person.

“Person” means any individual, partnership, limited liability company, joint venture, firm,
corporation, association, bank, trust or other enterprise, whether or not a legal entity, or any
government or political subdivision or any agency, department or instrumentality thereof.

5. Representations and Warranties. Borrower hereby represents and warrants to Lender
that:

(a) it is a duly organized and validly existing corporation in good standing under the
laws of the jurisdiction of its organization and has the corporate power and authority to
own and operate its properties, to transact the business in which it is now engaged and to
execute and deliver this Note;

(b) this Note constitutes the duly authorized, legally valid and binding obligation of
Borrower, enforceable against Borrower in accordance with its terms;

(c) all consents and grants of approval required to have been granted by any Person in

8. Miscellaneous.

(a) All notices and other communications provided for hereunder shall be in writing

other address as shall be designated by Lender or Borrower. All such notices and
communications shall, when mailed, telecopied or delivered by overnight courier, be

(b) Borrower shall indemnify Lender against any losses, claims, damages and liabilities
and related expenses, including counsel fees and expenses, incurred by Lender arising out of

incurred in connection with the collection and enforcement of this Note.

(c) No failure or delay on the part of Lender or any other holder of this Note to
exercise any right, power or privilege under this Note and no course of dealing between
Borrower and Lender shall impair such right, power or privilege or operate as a waiver of
any default or an acquiescence therein, nor shall any single or partial exercise of any such
right, power or privilege preclude any other or further exercise thereof or the exercise of
any other right, power or privilege. The rights and remedies expressly provided in this
Note are cumulative to, and not exclusive of, any rights or remedies that Lender would
otherwise have. No notice to or demand on Borrower in any case shall entitle Borrower to
any other or further notice or demand in similar or other circumstances or constitute a
waiver of the right of Lender to any other or further action in any circumstances without
notice or demand.

(d) Borrower and any endorser of this Note hereby consent to renewals and extensions of
time at or after the Maturity Date, without notice, and hereby waive diligence, presentment,

(e) THIS NOTE AND THE RIGHTS AND OBLIGATIONS OF BORROWER AND LENDER HEREUNDER SHALL BE

THE STATE OF CALIFORNIA, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES.

(f) ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST BORROWER ARISING OUT OF OR RELATING TO
THIS NOTE MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE
STATE OF CALIFORNIA, AND BY EXECUTION AND DELIVERY OF THIS NOTE BORROWER ACCEPTS FOR ITSELF
AND IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE NONEXCLUSIVE
JURISDICTION OF THE AFORESAID COURTS AND WAIVES ANY DEFENSE OF FORUM NON CONVENIENS AND
IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH THIS
NOTE. Borrower hereby agrees that service of all process in any such proceeding in any such
court may be made by registered or certified mail, return receipt requested, to Borrower at
its address set forth below its signature hereto, such service being hereby acknowledged by
Borrower to be sufficient for personal jurisdiction in any action against Borrower in any
such court and to be otherwise effective and binding service in every respect. Nothing
herein shall affect the right to serve process in any other manner permitted by law or shall
limit the right of Lender to bring proceedings against Borrower in the courts of any other
jurisdiction.

(g) BORROWER AND, BY THEIR ACCEPTANCE OF THIS NOTE, LENDER AND ANY SUBSEQUENT HOLDER OF
THIS NOTE HEREBY IRREVOCABLY AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY
CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS NOTE OR ANY DEALINGS BETWEEN THEM
RELATING TO THE SUBJECT MATTER OF THIS NOTE AND THE LENDER/BORROWER RELATIONSHIP THAT IS
BEING ESTABLISHED. The scope of this waiver is intended to be all-encompassing of any and
all disputes that may be filed in any court and that relate to the subject matter of this
transaction, including, without limitation, contract claims, tort claims, breach of duty
claims and all other common law and statutory claims. Borrower and, by their acceptance of
this Note, Lender and any subsequent holder of this Note each (i) acknowledges that this
waiver is a material inducement to enter into a business relationship, that each has already
relied on this waiver in entering into this relationship and that each will continue to rely
on this waiver in their related future dealings, and (ii) further warrants and represents
that each has reviewed this waiver with its legal counsel and that each knowingly and
voluntarily waives its jury trial rights following consultation with legal counsel. THIS
WAIVER IS IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND
THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS
OF THIS NOTE. In the event of litigation, this provision may be filed as a written consent
to a trial by the court.

(h) Borrower hereby waives the benefit of any statute or rule of law or judicial
decision, including without limitation California Civil Code § 1654, which would otherwise
require that the provisions of this Note be construed or interpreted most strongly against
the party responsible for the drafting thereof.
