          title insurance from Commonwealth Land Title Company with their
          standard provisions and exceptions (the "Title Policy") in the amount

          3.1.1. Real property taxes and assessments, which are a lien not yet
               due;

          3.1.2. Covenants, conditions, reservations (including exceptions of

          During the Inspection Period (hereafter defined) Buyer shall review
          and approve the Title Documents (hereinafter defined) and the Survey

          that are unacceptable to Buyer (the "Title Defects"), then prior to
          the expiration of the Inspection Period, Buyer shall provide Seller
          with, written notice of Buyer's objections. Seller may, at its sole

          objections, Seller shall be deemed to have elected not to cure or
          remove Buyer's title objections, and Buyer shall be entitled, as
          Buyer's sole and exclusive remedy, either to (i) terminate this
          Agreement and obtain a refund of the Deposit by providing written
          notice of termination to Seller before the end of the Inspection
          Period and returning the Due Diligence Items (hereinafter defined), or
          (ii) waive the objections and close this transaction as otherwise
          contemplated herein, without a reduction in

                                        3

          the Purchase Price. If Buyer shall fail to terminate this Agreement
          during the Inspection Period, all matters shown on the Survey or
          described in the Title Report, except for monetary liens for

               copies of all documents constituting exceptions to the title as

               to enter into any additional contracts or agreements prior to
               Close of Escrow which cannot be canceled upon thirty (30) days
               written notice without cost, penalty, or obligation unless such
               contracts or other agreements are approved by Buyer, which
               approval shall not be unreasonably withheld or delayed;

          4.1.4. All site plans, leasing plans, as-built plans, drawings,

               used in the units, if any.

     4.2. Estoppel Certificates.

          As a condition precedent to Buyer's obligation to acquire the
          Property, Seller shall obtain and deliver to Buyer estoppel
          certificates, in accordance with their respective Leases, from tenants
          representing seventy percent (70%) of the square feet which are leased
          and occupied by tenants as of the date this Agreement is fully
          executed. Estoppel certificates shall be deemed to satisfy this
          condition precedent unless they disclose material adverse matters.
          Buyer shall notify Seller within three (3) business days of receipt of
          a copy of the executed estoppel certificate of its approval or
          disapproval and the basis of such disapproval, if disapproved. If
          Buyer disapproves of an estoppel certificate because of a material,
          adverse matter disclosed therein, and Seller is unable to obtain a
          reasonably acceptable estoppel certificate prior to the Close of
          Escrow, this Agreement shall terminate, Buyer shall be entitled to a
          refund of the Deposit, and neither party shall have any further
          obligation to the other except Buyer's indemnification obligations
          under Paragraph 5, and any other obligations expressly set forth
          herein.

5.   Inspections.

     Buyer, at its sole cost and expense, shall have the right to conduct
feasibility, environmental, engineering and physical studies or other tests (the
"Inspections") of the Property at any time during the Inspection Period
(hereinafter defined). Buyer, and its duly authorized agents or representatives,
shall be permitted to enter upon the Property at all reasonable times during the
Inspection Period in order to conduct engineering studies, soil tests and any
other Inspections and/or tests that Buyer may deem necessary or advisable. Buyer
must arrange all Inspections of the Property with Seller at least two (2)
business days in advance of any Inspections. In the event that the review and/or
Inspection conducted pursuant to this paragraph shows any fact, matter or
condition to exist with respect to the Property

                                        5

<PAGE>

that is unacceptable to Buyer, in Buyer's sole subjective discretion, then Buyer
shall be entitled, as its sole and exclusive remedy, to (1) terminate this
Agreement and obtain a refund of the Deposit, or (2) waive the objection, and
close the transaction as otherwise contemplated herein without any reduction in
the Purchase Price. Buyer agrees to promptly discharge any liens that may be
imposed against the Property as a result of the Inspections and to defend,
indemnify and hold Seller harmless from all, claims, suits, losses, costs,
expenses (including without limitation court costs and attorneys' fees),
liabilities, judgments and damages incurred by Seller as a result of any
Inspections.

               execution of the Purchase and Sale Agreement ("Inspection
               Period") to approve or disapprove the Inspections. If Buyer shall
               fail to notify Seller and Escrow Holder of its disapproval of the
               Inspections in writing within the Inspection Period, the
               condition of the Property shall be deemed approved. If Buyer
               shall disapprove the Inspections within the Inspection Period,
               this Agreement and the Escrow shall thereupon be terminated.
               Buyer shall not be entitled to purchase the Property, Seller
               shall not be obligated to sell the Property to Buyer, and the
               parties shall be relieved of any further obligation to each other
               with respect to the Property, except as expressly provided in
               Paragraph 5.

          5.1.2. Notwithstanding anything to the contrary contained herein,
               Buyer hereby agrees that, in the event this Agreement is
               terminated for any reason, then Buyer shall promptly and at its
               sole expense return to Seller all Due Diligence Items which have
               been delivered by Seller to Buyer in connection with the
               Inspections, along with copies of all reports, drawings, plans,
               studies, summaries, surveys, maps and other data prepared by
               third parties relating to the Property, subject to restrictions
               on Buyer's ability to make any such materials available to Seller
               that are imposed in any agreement with a third party consultant
               preparing any such reports or materials ("Buyer's Reports").
               Buyer shall cooperate with Seller at no expense to Buyer in order
               to obtain a waiver of any such limitations.

          5.1.3. Notwithstanding any contrary provision of this Agreement, Buyer
               acknowledges that Seller is not representing or warranting that
               any of the Due Diligence Items prepared by third parties are
               accurate or complete, such as the Survey, engineering reports and
               the like. Seller advises Buyer to

                                        6

               independently verify the facts and conclusions set forth therein,
               provided however, Seller warrants that it has no knowledge of any
               material errors or misstatements in such information regarding

     Seller hereby represents and warrants as of the date hereof to Buyer as
follows:

     7.1. Seller is a limited partnership duly formed and validly existing under
          the laws of the State of Texas. Seller has full power and authority to
          enter into this Agreement, to perform this Agreement and to consummate
          the transactions contemplated hereby. The execution, delivery and
          performance of this Agreement and all documents contemplated hereby by
          Seller have been duly and validly authorized by all necessary action
          on the part of Seller and all required consents and approvals have
          been duly obtained and will not result in a breach of any of the terms
          or provisions of, or constitute a default under any indenture,
          agreement or instrument to which Seller is a party. This Agreement is
          a legal, valid and binding obligation of Seller, enforceable against
          Seller in accordance with its terms, subject to the effect of
          applicable bankruptcy, insolvency, reorganization, arrangement,
          moratorium or other similar laws affecting the rights of creditors
          generally.

                                       11

<PAGE>

     7.2. Seller has good and marketable title to the Property, subject to the
          conditions of title. There are no outstanding rights of first refusal,
          rights of reverter or option relating to the Property or any interest
          therein. To Seller's knowledge, there are no unrecorded or undisclosed
          documents or other matters which affect title to the Property. Subject
          to the Leases, Seller has enjoyed the continuous and uninterrupted
          quiet possession, use and operation of the Property, without material
          complaint or objection by any person.

     7.3. Seller is not a "foreign person" within the meaning of Section 1445(f)
          of the Internal Revenue Code of 1986, as amended (the "Code").

     7.4. Covenants of Seller. Seller hereby covenants as follows:

          7.4.1. At all times from the date hereof through the date of closing,
               Seller shall cause to be in force fire and extended coverage
               insurance upon the Property, and public liability insurance with
               respect to damage or injury to persons or property occurring on
               the Property in at least such amounts as are maintained by Seller
               on the date hereof;

          7.4.2. From the date of execution of this Agreement through the date
               of closing, Seller will not enter into any new lease with respect
               to the Property, without Buyer's prior written consent, which
               shall not be unreasonably withheld. Exercise of a renewal option
               shall not be considered a new lease. Any brokerage commission
               payable with respect to a new lease shall be prorated between
               Buyer and Seller in accordance with their respective periods of
               ownership as it bears to the primary term of the new lease.
               Further, Seller will not modify any existing Lease covering space
               in the Property without first obtaining the written consent of
               Buyer which shall not be unreasonably withheld, conditioned or
               delayed. Buyer shall have five (5) business days in which to
               approve or disapprove of any new lease for which it has a right
               to consent. Failure to respond in writing within said time period
               shall be deemed to be consent;

          7.4.3. From the date of execution of this Agreement through the date
               of closing, Seller shall not sell, assign, or convey any right,
               title or interest whatsoever in or to the Property, or create or
               permit to attach any lien, security interest, easement,
               encumbrance, charge, or condition affecting the Property (other
               than the Permitted Exceptions) without promptly discharging the
               same prior to closing;

                                       12

<PAGE>

          7.4.4. Seller shall not, without Buyer's written approval, (a) amend
               or waive any right under any Service Contract, or (b) enter into
               any agreement of any type affecting the Property that would
               survive the Closing Date;

          7.4.5. Seller shall fully and timely comply with all obligations to be
               performed by it under the Leases, the Contracts, and all permits,
               licenses, approvals and laws, regulations and orders applicable
               to the Property.

     7.5  Approval of Property. The consummation of the purchase and sale of the
          Property pursuant to this Agreement shall be deemed Buyer's
          acknowledgement that it has had an adequate opportunity to make such
          legal, factual and other inspections, inquiries and investigations as
          it deems necessary, desirable or appropriate with respect to the
          Property. Such inspections, inquiries and investigations of Buyer
          shall be deemed to include, but shall not be limited to, any leases
          and contracts pertaining to the Property, the physical components of
          all portions of the Property, the physical condition of the Property,
          such state of facts as an accurate survey, environmental report and

          rely upon, Seller or Seller's agents with regard to, and Seller will
          not make any representation or warranty with respect to: (i) the
          quality, nature, adequacy or physical condition of the Property
          including, but not limited to, the structural elements, foundation,
          roof, appurtenances, access, landscaping, parking facilities, or the

          the quality of any labor or materials relating in any way to the
          Property; or (viii) the condition of title to the Property or the

          this Agreement, to perform this Agreement and to consummate the
          transactions contemplated hereby. The execution, delivery and
          performance of this Agreement and all documents contemplated hereby by
          Buyer have been duly and validly authorized by all necessary action on

          duly obtained and will not result in a breach of any of the terms or
          provisions of, or constitute a default under any indenture, agreement
          or instrument to which Buyer is a party. This Agreement is a legal,
          valid and binding obligation of Buyer, enforceable against Buyer in
          accordance with its terms, subject to the effect of applicable
          bankruptcy, insolvency, reorganization, arrangement, moratorium or
          other similar laws affecting the rights of creditors generally.

9.   Conditions Precedent to Closing.

     The obligations of Buyer pursuant to this Agreement shall, at the option of
Buyer, be subject to the following conditions precedent:

     9.1. All of the representations, warranties and agreements of Seller set
          forth in this Agreement shall be true and correct in all material
          respects as of the date hereof, and Seller shall not have on or prior
          to closing, failed to meet, comply with or perform in any material
          respect any conditions or agreements on Seller's part as required by
          the terms of this Agreement.

     9.2. There shall be no material change in the matters reflected in the
          Title Report, and there shall not exist any encumbrance or title
          defect affecting the Property not described in the Title Report except
          for the Permitted Exceptions or matters to be satisfied at closing.

     9.3. Unless Seller receives notice from Buyer at least thirty (30) days
          prior to closing, effective as of closing, the management agreement
          affecting the Property shall be terminated by Seller and any and all
          termination fees incurred as a result thereof shall be the sole
          obligation of Seller.

     9.4. Seller shall have operated the Property from and after the date hereof
          in substantially the same manner as prior thereto.

     9.5. If any such condition is not fully satisfied by closing, Buyer shall
          so notify Seller and may terminate this Agreement by written notice to

                                       15

<PAGE>

          Seller whereupon this Agreement may be canceled, and upon return of
          the Due Diligence Items the Deposit shall be paid to Buyer and,
          thereafter, neither Seller nor Buyer shall have any continuing
          obligations hereunder.

     9.6. If Buyer notifies Seller of a failure to satisfy the conditions
          precedent set forth in this paragraph, Seller may, within five (5)
          days of receipt of Buyer's Notices agree to satisfy the condition by
          written notice to Buyer, and Buyer shall thereupon be obligated to
          close the transaction provided Seller so satisfies such condition. If
          Seller fails to agree to cure or fails to cure such condition by the
          Closing Date, this Agreement shall be canceled and the Deposit shall
          be returned to Buyer and neither party shall have any further
          liability hereunder.

     9.7. If Buyer's acquisition of the Property is part of a tax-deferred
          exchange pursuant to Section 1031 of the Code, it is a condition
          precedent to the closing of this Escrow that Buyer is able to complete
          an exchange for all or a portion of its relinquished property pursuant
          to an Exchange Agreement between Buyer and Accommodator. Seller agrees
          to execute such documents or instruments as may be necessary or
          appropriate to evidence such exchange, provided that Seller's
          cooperation in such regard shall be at no additional cost, expense, or
          liability whatsoever to Seller, and that no additional delays in the
          scheduled Close of Escrow are incurred unless mutually agreed upon by
          all parties to this Agreement.

10. Damage or Destruction Prior to Close of Escrow.

     In the event that the Property should be damaged by any casualty prior to
the Close of Escrow, then if the cost of repairing such damage, as estimated by
an architect or contractor retained pursuant to the mutual agreement of the
parties, is:

     10.1. Less than Two Hundred Fifty Thousand Dollars ($250,000), the Close of
          Escrow shall proceed as scheduled and any insurance proceeds shall be
          distributed to Buyer to the extent not expended by Seller for
          restoration;

or if said cost is:

     10.2. Greater than Two Hundred Fifty Thousand Dollars ($250,000), then
          either Seller or Buyer may elect to terminate this Agreement, in which
          case upon return of the Due Diligence Items the Deposit shall be
          returned to Buyer and neither party shall have any further obligation
          to the other except for Buyer's indemnification obligations under
          Paragraph 5.

                                       16

<PAGE>

11. Eminent Domain.

     11.1. If, before the Close of Escrow, proceedings are commenced for the
          taking by exercise of the power of eminent domain of all or a material
          part of the Property which, as reasonably determined by Buyer, would
          render the Property unacceptable to Buyer or unsuitable for Buyer's
          intended use, Buyer shall have the right, by giving notice to Seller
          within thirty (30) days after Seller gives notice of the commencement
          of such proceedings to Buyer, to terminate this Agreement, in which
          event this Agreement shall terminate, and upon the return of the Due
          Diligence Items, the Deposit shall be returned to Buyer and neither
          party shall have any further obligation to the other except for
          Buyer's indemnification under Paragraph 5, or as otherwise expressly
          set forth herein. If, before the Close of Escrow, proceedings are
          commenced for the taking by exercise of the power of eminent domain of
          less than such a material part of the Property, or if Buyer has the
          right to terminate this Agreement pursuant to the preceding sentence
          but Buyer does not exercise such right, then this Agreement shall
          remain in full force and effect and, at the Close of Escrow, the
          condemnation award (or, if not therefore received, the right to
          receive such portion of the award) payable on account of the taking
          shall be transferred in the same manner as title to the Property is
          conveyed. Seller shall give notice to Buyer within three (3) business
          days after Seller's receiving notice of the commencement of any
          proceedings for the taking by exercise of the power of eminent domain
          of all or any part of the Property.

12. Notices.

     12.1. All notices, demands, or other communications of any type given by
          any party hereunder, whether required by this Agreement or in any way
          related to the transaction contracted for herein, shall be void and of
          no effect unless given in accordance with the provisions of this
          Paragraph. All notices shall be in writing and delivered to the person
          to whom the notice is directed, either in person, by United States

                                ESCROW AGREEMENT

     THIS ESCROW AGREEMENT (this "Agreement") is made and entered into as of the
_____ day of August, 2005, between NNN VF SOUTHWOOD TOWER, L.P., a Texas limited
partnership ("Seller"), RANCHO PACIFIC DEVELOPMENT ("Purchaser"), and
__________________ ("Escrow Agent").

                                    RECITALS

     A. Seller and Purchaser entered into a Purchase and Sale Agreement dated as
of August_______, 2005 (the "PSA") for the purchase and sale of certain real
property located at 19221 Interstate 45, Shenandoah (Montgomery County), Texas,
as more particularly described in the PSA (the "Property"). Any capitalized
terms not defined herein shall have the meanings set forth in the PSA.

     B. Section 24 of the PSA provides that Seller will guaranty the current
vacancy of the Property at the rate of Twenty Dollars ($20) per square foot,
gross. The guaranty shall continue for a period of five (5) years from the date
of closing or until such time as the Vacant Space (hereinafter defined) is
leased pursuant to the terms and conditions of this Agreement, whichever is
sooner.

     NOW THEREFORE, in consideration of the mutual covenants and premises herein
contained, and other good and valuable consideration, and intending to be
legally bound hereby, the parties hereby agree as follows:

     1.   VACANT SPACE ESCROW.

          (a) At closing Seller shall deposit with Escrow Agent in an
interest-bearing account, the estimated amount of $1,329,100 (calculated by
multiplying (i) $20.00 of potential lost annual rent per square foot, gross,
multiplied by (ii) the lesser of 13,291 square feet (the estimated amount of
vacant space as of the execution of the PSA), or the amount of vacant space
remaining as of the closing date (the "Vacant Space"), multiplied by (iii) five
(5) years) (the "Escrow"). The Escrow shall remain in effect for five (5) years
from the date of closing or until such time as the Vacant Space is fully leased
in accordance with this Agreement, whichever is sooner. The Vacant Space is more
particularly described on Exhibit B attached hereto and incorporated herein. The
Escrow may be contributed from the Purchase Price proceeds.

          (b) Seller and Purchaser shall cooperate in leasing the Vacant Space,
and each party shall use commercially reasonable efforts to lease the Vacant
Space to acceptable tenants. Seller shall have the right to use any leasing
brokers Seller desires, in Seller's sole and absolute discretion. Purchaser
grants Seller complete and unrestricted access to the Vacant Space twenty-four
(24) hours a day, seven (7) days a week for the purpose of showing the Vacant
Space to potential tenants and improving the Vacant Space prior to occupancy by
new tenants. Purchaser

                                       26

<PAGE>

shall give Seller keys and security cards to the building and the Vacant Space,
which Seller may use at any time until the Vacant Space is completely leased and
the Escrow is returned to Seller. Purchaser shall maintain the Vacant Space in a
clean and showable condition, and Purchaser shall replace the light bulbs and
perform any maintenance necessary to keep the Vacant Space in a good condition.
All potential tenants for the Vacant Space shall have financials reasonably
acceptable to Seller and Purchaser and shall be reasonably approved by both
parties prior to lease execution. If Purchaser does not approve of a tenant for
financial reasons, Purchaser nevertheless agrees to execute a lease with such
tenant. In such case, the rent from the lease shall be paid directly to Seller,
the Rent Payment (hereinafter defined) shall be paid to Purchaser in accordance
with Section (d) below, and the Escrow funds shall not be released to Seller
with respect to such lease until the expiration of the five (5) year period, or
until such time as the space is re-let to a tenant acceptable to Purchaser,
whichever is sooner. Purchaser shall cooperate with Seller in any and all
collection actions or other related proceedings with respect to leasing the
Vacant Space.

          (c) Each party agrees to indemnify and hold the other party harmless
from any and all claims, actions, damages, liabilities and expenses (including
reasonable attorneys' fees) in connection with damage to the Vacant Space
arising from or out of the showing of the Vacant Space, or any part thereof, by
the other party.

          (d) Upon the execution of a lease, the amount of Vacant Space shall be
reduced pro rata based on the rent being paid, the term of the lease and/or the
amount of space being leased by the new tenant, and the Escrow shall be reduced
accordingly. At such time, Seller shall deliver a certification to the Escrow
Agent, detailing the amount of the Escrow to be released to Seller (the "Escrow
Refund"), and the Escrow Agent shall disburse the Escrow Refund to Seller into
that certain account described on Exhibit A attached hereto and incorporated
herein. For example, if 2,000 square feet of the Vacant Space is leased for five
(5) years at $20.00 per square foot, the Vacant Space shall be reduced to 11,291
square feet, and the Escrow shall be reduced by $200,000, for a new total Escrow
of $1,129,100. Alternately, if 2,000 square feet of the Vacant Space is leased
for three (3) years at $18.00 per square foot, the Vacant Space shall be reduced
to 11,291 square feet, and the Escrow shall be reduced by $108,000, for a new
total of $1,221,100.

          (e) Beginning on the fifteenth (15th) day of each calendar month
following __________________, 2005, and until such time as the amount of Vacant
Space is completely leased, unless the Escrow Agent has received a certification
from Seller that the Escrow shall be reduced in accordance with section (c)
above, the Escrow Agent shall, without instruction from either party, disburse
approximately $22,151.67 to be adjusted at closing (the "Rent Payment") to
Purchaser into that certain account described on Exhibit A attached hereto and
incorporated herein.

          (f) Any balance remaining in the Escrow on _________________, 2010,
shall be disbursed to Seller immediately.

     2. DISPUTES. In the event of a dispute between any of the parties hereto as
to their respective rights and interests hereunder, the Escrow Agent shall be
entitled to hold any and all

                                       27

cash then in its possession hereunder until such dispute shall have been
resolved by the parties in dispute and the Escrow Agent shall have been notified
by instrument jointly signed by all of the parties in dispute, or until such
dispute shall have been finally adjudicated by a court of competent
