                  Re:      G REIT, Inc.
                           ------------
Ladies and Gentlemen:

          G REIT, Inc., a Virginia corporation (the "Company"), will issue in a
public offering (the "Offering") its common stock (the "Stock") pursuant to a
Registration Statement on Form S-11 filed by the Company with the Securities and
Exchange Commission. NNN Capital Corp., a California corporation (the "Dealer
Manager"), will act as dealer manager for the offering of the Stock. The Company
is entering into this agreement with you to set forth the terms on which you, as
Escrow Agent, will hold and disburse the proceeds from subscriptions for the
purchase of the Stock in the Offering until such time as: (i) subscriptions from
nonaffiliates of the Company have been received for Stock, resulting in total
minimum capital raised of $1,000,000 (the "Required Capital"); (ii) in the case
of subscriptions received from residents of Pennsylvania ("Pennsylvania
Investors"), the Company has received subscriptions for Stock resulting in total
minimum capital raised of $20,000,000, not including subscriptions from
Pennsylvania Investors (the "Pennsylvania Required Capital"); and (iii) in the
case of subscriptions received from residents of Oregon ("Oregon Investors"),
the Company has received subscriptions for Stock resulting in total minimum
capital raised of $20,000,000, not including subscriptions from Oregon Investors
(the "Oregon Required Capital").

          Based upon your representation and warranty that you are, and at all
times during the term of this agreement will be, deemed a "bank" as that term is
defined in Section 3(a)(6) of the Securities Exchange Act of 1934, as amended,
the Company hereby appoints you as Escrow Agent for purposes of holding the
proceeds from the subscriptions for the Stock, on the terms and conditions
hereinafter set forth:

   1. Persons subscribing to purchase the Stock will be instructed by the Dealer
Manager or any soliciting dealers to remit the purchase price in the form of
checks, drafts, or money orders (hereinafter called "instruments of payment")
payable to the order of, or funds wired in favor of, "PriVest Bank, as Escrow
Agent." Any checks received made payable to a party other than the Escrow Agent
shall be returned to the soliciting dealer who submitted the check. Within one
(1) business day after receipt of instruments of payment from the Offering, the
Dealer Manager will send to you: (a) each subscriber's name, address, number of
shares purchased,

<PAGE>


and purchase price remitted, and (b) the instruments of payment from such
subscribers, for deposit by you into an interest-bearing deposit account
entitled "ESCROW ACCOUNT FOR THE BENEFIT OF SUBSCRIBERS FOR COMMON STOCK OF G
REIT, INC." (the "Escrow Account"), which deposit shall occur within one (1)
business day after you receive such materials. Instruments of payment and wired
funds received from Pennsylvania Investors (as identified as such by the
Company) shall be placed in a separate interest-bearing deposit account entitled
"ESCROW ACCOUNT FOR THE BENEFIT OF PENNSYLVANIA INVESTORS" (the "Pennsylvania
Escrow Account"). Instruments of payment and wired funds received from Oregon
Investors (as identified as such by the Company) shall be placed in a separate
interest-bearing deposit account entitled "ESCROW ACCOUNT FOR THE BENEFIT OF
OREGON INVESTORS" (the "Oregon Escrow Account"). Each of the Escrow Account,
Pennsylvania Escrow Account, and Oregon Escrow Account will be established and
maintained in such a way as to permit the interest income calculations described
in paragraph 7(a).

     2. You agree to promptly process for collection the instruments of payment
upon deposit into either the Escrow Account, the Pennsylvania Escrow Account, or
the Oregon Escrow Account. You will hold the deposited funds in the Escrow
Account, the Pennsylvania Escrow Account, and the Oregon Escrow Account until
such funds are disbursed in accordance with paragraph 3 hereof. If any of the
instruments of payment are returned to you for nonpayment prior to receipt by
you of the Required Capital or, in connection with subscriptions from
Pennsylvania Investors, the Pennsylvania Required Capital or, in connection with
subscriptions from Oregon Investors, the Oregon Required Capital, you shall
promptly notify the Dealer Manager and the Company in writing of such
nonpayment, and you are authorized to debit the Escrow Account, the Pennsylvania
Escrow Account, or the Oregon Escrow Account, as applicable, in the amount of
such return payment as well as any interest earned on the amount of such
payment.

     3. (a) Subject to the provisions of subparagraphs 3(b)-3(e) below:

            (i) once you have received and collected subscription proceeds in
the Escrow Account in collected funds an amount equal to or greater than the
Required Capital, you shall promptly notify the Company and, upon receiving
written instruction from the Company, (A) disburse to the Company, by check or
wire transfer, the funds in the Escrow Account representing the gross purchase
price for the Stock, and (B) disburse to the subscribers any interest thereon
calculated pursuant to the provisions of paragraph 7. For purposes of this
Agreement, the term "collected funds" shall mean all funds received by the
Escrow Agent have cleared normal banking channels and are in the form of cash.
Following such disbursements, the Escrow Account shall close and thereafter you
shall forward directly to the Company upon receipt by you any subscription
documents and instruments of payment received by you from subscribers other than
Pennsylvania Investors and Oregon Investors.

                                       2

<PAGE>


            (ii) after the closing of the Escrow Account, the Company and the
Dealer Manager shall continue to forward to you instruments of payment and
subscriber information received from Pennsylvania Investors for deposit into the
Pennsylvania Escrow Account until such time as the Company notifies you in
writing that total subscription proceeds (not including the amount then in the
Pennsylvania Escrow Account) equal or exceed the Pennsylvania Required Capital.
Upon your receipt of a written notice from the Company that total subscription
proceeds (not including the amount then in the Pennsylvania Escrow Account)
equalling or exceeding the Pennsylvania Required Capital have been received in
collected funds, you shall (A) disburse to the Company, by check or wire
transfer, the funds then in the Pennsylvania Escrow Account representing the
gross purchase price for the Stock, and (B) disburse to the Pennsylvania
Investors any interest thereon calculated pursuant to the provisions of
paragraph 7. Following such disbursements, the Pennsylvania Escrow Account will
close and thereafter you shall forward directly to the Company upon receipt by
you any subscription documents and instruments of payment received by you.

            (iii) after the closing of the Escrow Account, the Company and the
Dealer Manager shall continue to forward to you instruments of payment and
subscriber information received from Oregon Investors for deposit into the
Oregon Escrow Account until such time as the Company notifies you in writing
that total subscription proceeds (not including the amount then in the Oregon
Escrow Account) equal or exceed the Oregon Required Capital. Upon your receipt
of a written notice from the Company that total subscription proceeds (not
including the amount then in the Oregon Escrow Account) equalling or exceeding
the Oregon Required Capital have been received in collected funds, you shall (A)
disburse to the Company, by check or wire transfer, the funds then in the Oregon
Escrow Account representing the gross purchase price for the Stock, and (B)
disburse to the Oregon Investors any interest thereon calculated pursuant to the
provisions of paragraph 7. Following such disbursements, the Oregon Escrow
Account will close and thereafter you shall forward directly to the Company upon
receipt by you any subscription documents and instruments of payment received by
you.

        (b) If, at the close of business on __________ ___, 200__ (the
"Expiration Date") you are not in receipt of evidence of subscriptions accepted
on or before such date, and instruments of payment dated not later than that
date (or actual wired funds), for the purchase of Stock providing for total
purchase proceeds that equal or exceed the Required Capital (from all sources
but exclusive of any funds received from subscriptions for Stock from entities
which the Company has notified you are affiliated with the Company or its
affiliates), you shall promptly so notify the Company. Thereafter, you agree to
request an executed IRS Form W-9 from each subscriber within ten (10) calendar
days after you provide such notice. On the tenth (10th) day following the date
of your receipt of the notice, you shall promptly return directly to each
subscriber by your check the collected funds deposited in the Escrow Account,
the Pennsylvania Escrow Account, and the Oregon

                                       3

<PAGE>


Escrow Account on behalf of such subscriber (unless earlier disbursed in
accordance with paragraph 3(c) below), or shall return the instruments of
payment delivered to you if such instruments have not been processed for
collection prior to such time, together with interest in the amounts calculated
pursuant to paragraph 7 for each subscriber at the address given to you by the
Dealer Manager or the Company. In the event an executed Form W-9 is not received
by you from each subscriber within such period, you shall thereupon remit an
amount to the subscribers in accordance with the provisions hereof, withholding
thirty-one percent (31%) of any interest income on subscription proceeds
(determined in accordance with paragraph 7) attributable to those subscribers
not furnishing executed forms in accordance with IRS Regulations. However, you
shall not be required to remit any payments until funds represented by such
payments have been collected by you.

         (c) Notwithstanding subparagraphs 3(a) and 3(b) above, if you are not
in receipt of evidence of subscriptions accepted on or before the close of
business on such date that is 120 days after commencement of the Offering (the
Company will notify you of the commencement date of the Offering) (the "Initial
Escrow Period"), and instruments of payment dated not later than that date (or
actual wired funds), for the purchase of Stock providing for total purchase
proceeds (from all sources other than Pennsylvania Investors) that equal or
exceed the Pennsylvania Required Capital, you shall promptly so notify the
Company. Thereafter, the Company shall send to each Pennsylvania Investor by
certified mail within ten (10) calendar days after the end of the Initial Escrow
Period a notification in the form of Exhibit A. If, pursuant to such
                                     ---------
notification, a Pennsylvania Investor requests the return of his or her
subscription funds within ten (10) calendar days after receipt of the
notification (the "Request Period"), you agree to request an executed IRS Form
W-9 from each such Pennsylvania Investor within ten (10) calendar days after you
receive such notice from such Pennsylvania Investor. You shall promptly return
directly to each Pennsylvania Investor by your check the collected funds
deposited in the Pennsylvania Escrow Account on behalf of each Pennsylvania
Investor, or shall return the instruments of payment delivered to you if such
instruments have not been processed for collection prior to such time, at the
address given to you by the Dealer Manager or the Company, together with
interest income in the amounts calculated pursuant to paragraph 7 for each
subscriber. If an executed Form W-9 is not received by you from such
Pennsylvania Investor within such period, you shall thereupon remit an amount to
such Pennsylvania Investor in accordance with the provisions hereof, withholding
thirty-one percent (31%) of any interest income earned on subscription proceeds
(determined in accordance with paragraph 7) attributable to such Pennsylvania
Investor not furnishing executed forms in accordance with IRS Regulations.
However, you shall not be required to remit any payments until funds represented
by such payments have been collected by you.

         (d) The subscription funds of Pennsylvania Investors who do not request
the return of their subscription funds within the Request Period shall

                                       4

<PAGE>


remain in the Pennsylvania Escrow Account for successive 120-day escrow periods
(each, a "Successive Escrow Period"), each commencing automatically upon the
termination of the prior Successive Escrow Period, and the Company and Escrow
Agent shall follow the notification and payment procedure set forth in
subparagraph 3(c) above with respect to the Initial Escrow Period for each
Successive Escrow Period until the occurrence of the earliest of (i) the
Expiration Date, (ii) the receipt and acceptance by the Company of subscriptions
for the purchase of Stock with total collected funds that equal or exceed the
Pennsylvania Required Capital and the disbursement of the Pennsylvania Escrow
Account on the terms specified herein, or (iii) all funds held in the
Pennsylvania Escrow Account having been returned to the Pennsylvania Investors
in accordance with the provisions hereof.

     (e) If the Company rejects any subscription for which you have already
collected funds, you shall, upon the written request of the Company, promptly
issue a refund check to the rejected subscriber. If the Company rejects any
subscription for which you have not yet collected funds but have submitted the
subscriber's check for collection, you shall promptly issue a check in the
amount of the subscriber's check to the rejected subscriber after you have
cleared such funds. If you have not yet submitted a rejected subscriber's check
for collection, you shall promptly remit the subscriber's check directly to the
subscriber.

     4. You shall report to the Company weekly the account balances in each of
the Escrow Account, the Pennsylvania Escrow Account, and the Oregon Escrow
Account and the activity in each account since the last report.

     5. Prior to the disbursement of funds deposited in the Escrow Account , the
Pennsylvania Escrow Account, or the Oregon Escrow Account in accordance with the
provisions of paragraph 3 hereof, you shall invest all of the funds deposited in
the Escrow Account, the Pennsylvania Escrow Account, and the Oregon Escrow
Account in "Short-Term Investments" (as defined below) in compliance with SEC
Rule 15c2-4 and you are further authorized and you agree to reinvest all
earnings and interest derived therefrom in Short-Term Investments specified
below. In the event that instruments of payment are returned to you for
nonpayment, you are authorized to debit the Escrow Account, the Pennsylvania
Escrow Account, or the Oregon Escrow Account, as applicable, in accordance with
paragraph 2 hereof.

        "Short-Term Investments" include obligations of, or obligations
guaranteed by, the United States government or bank money-market accounts or
certificates of deposit of national or state banks that have deposits insured by
the Federal Deposit Insurance Corporation (including certificates of deposit of
any bank acting as a depository or custodian for any such funds, including,
without limitation, such certificates or instruments of American International
Bank) which mature on or before the Expiration Date, unless such instrument
cannot be readily

                                       5

<PAGE>


sold or otherwise disposed of for cash by the Expiration Date without any
dissipation of the offering proceeds invested.

     The following securities are not permissible investments:

     (a)      money market mutual funds;
     (b)      corporate equity or debt securities;
     (c)      repurchase agreements;
     (d)      bankers' acceptances;
     (e)      commercial paper; and
     (f)      municipal securities.

     6. You are entitled to rely upon written instructions you receive from the
Company, unless you have actual knowledge that such instructions are not valid
or genuine; provided that, if in your opinion, any instructions from the Company
are unclear, you may request clarification from the Company prior to taking any
action and if such instructions continue to be unclear, you may rely upon
written instructions from the Company's legal counsel in distributing or
continuing to hold any funds. However, you shall not be required to disburse any
funds attributable to instruments of payment which have not been collected by
you, provided you shall use your best efforts to promptly collect such funds
after your receipt of disbursement instructions from the Company and shall
disburse such funds in compliance with the disbursement instructions from the
Company.

     7. If the Offering terminates prior to receipt of the Required Capital or
one or more Pennsylvania Investors elects to have his or her subscription
returned in accordance with paragraph 3, interest income earned on subscription
proceeds deposited in the Escrow Account (the "Escrow Income"), the Pennsylvania
Escrow Account (the "Pennsylvania Escrow Income"), and the Oregon Escrow Account
(the "Oregon Escrow Income") shall be remitted to subscribers in accordance with
paragraph 3 and without any deductions for escrow expenses. Each subscriber's
pro rata portion of Escrow Income, Pennsylvania Escrow Income, or Oregon Escrow
Income shall be determined as follows: the total amount of Escrow Income (or
Pennsylvania Escrow Income or Oregon Escrow Income, as appropriate) shall be
multiplied by a fraction, (i) the numerator of which is determined by
multiplying the number of shares of Stock purchased by said subscriber times the
number of days said subscriber's proceeds are held in the Escrow Account, the
Pennsylvania Escrow Account, or the Oregon Escrow Account, as applicable, prior
to the date of disbursement, and (ii) the denominator of which is the total of
the numerators for all such subscribers in such account. The Company shall
reimburse the Escrow Agent for all escrow expenses. You shall remit all such
Escrow Income, Pennsylvania Escrow Income, and Oregon Escrow Income in
accordance with paragraph 3.

         You have tendered a subscription to purchase shares of common stock of

Company. The Pennsylvania guidelines provide that until this minimum amount of
offering proceeds is received by the Company, every 120 days during the offering
period Pennsylvania subscribers may request that their subscription be returned.

         If you wish to continue your subscription in escrow until the
Pennsylvania minimum subscription amount is received, nothing further is
required.

         If you wish to terminate your subscription for the Company's common
stock and have your subscription returned please so indicate below, sign, date,
