as the “Property”.

TERMS AND CONDITIONS

In consideration of the mutual covenants and agreements herein contained, and intending to be
legally bound hereby, the parties hereto agree:

1. Sale and Purchase. Seller hereby agrees to sell, transfer and convey the Property
to Buyer, and Buyer hereby agrees to purchase and accept the Property from Seller, for the purchase
price and on and subject to the other terms and conditions set forth in this Agreement.

2. Purchase Price. The purchase price for the Property (the “Purchase Price”) shall be
Sixty Seven Million Dollars U.S. ($67,000,000.00) which, subject to the terms and conditions
hereinafter set forth, shall be paid to Seller by Buyer as follows:

2.1 Deposit. Within one (1) business day after the execution of this Agreement, Buyer
shall deliver to the Escrow Agent cash in the amount of Seven Hundred Fifty Thousand Dollars U.S.
(U.S. $750,000.00) (the “Initial Deposit”) by wire transfer. Immediately upon receipt of the
Initial Deposit Escrow Agent shall pay over the Initial Deposit to Seller. The Initial Deposit
shall be nonrefundable except in the event of a default by Seller hereunder which results in the
termination of this Agreement prior to Closing, or in the event of a casualty or condemnation event
which results in the termination of this Agreement prior to Closing, in which case the Deposit,
without interest, shall be refunded by Seller to Buyer. If this Agreement is not terminated for any
reason, then on the business day after the expiration of the Inspection Period (as hereinafter
defined), Buyer shall deposit with Escrow Agent additional cash in the amount of Two Hundred Fifty
Thousand Dollars U.S. (U.S. $250,000.00) (the “Second Deposit”) by wire transfer. As hereinafter
used, the term “Deposit” shall mean the Initial Deposit and the Second Deposit. The Second Deposit
with Escrow Agent shall be placed in an interest-bearing account and all interest accrued thereon
shall increase and become a part of the Deposit. From and after the expiration of the Inspection
Period (as hereinafter defined), the Deposit (including the Second Deposit) shall be nonrefundable
except in the event of a default by Seller hereunder or except as otherwise provided herein. On the
Closing (as hereinafter defined), the Deposit shall be applied toward the payment of the Purchase
Price. Notwithstanding anything to the contrary contained in this Agreement if this Agreement is
terminated and Buyer is entitled to the return of the Earnest Money, then the sum of One Hundred
and No/100 Dollars ($100.00) (the “Independent Consideration”) shall be paid to Seller from the
Earnest Money, which amount Seller and Buyer have bargained for and agreed to as independent and
sufficient consideration for Seller’s execution and delivery of this Agreement. The Independent
Consideration is non-refundable and in addition to any other payment or deposit required by this
Agreement, and Seller shall retain the Independent Consideration notwithstanding any other
provision of this Agreement to the contrary.

2.2 Cash at Closing. Not later than 11 a.m. (Pacific Time) on the Closing Date
(provided that Buyer shall not be in default hereunder for failure to timely deliver the balance of
the Purchase Price if Buyer has acted diligently), Buyer shall deliver to Escrow Agent cash in an
amount of the balance of the Purchase Price (less the amount of the Credit against the Purchase
Price set forth in Section 6.3.1 hereof) plus the costs, expenses and prorations required to be
paid by Buyer hereunder.

3. Conditions Precedent to Buyer’s Obligations. All of Buyer’s obligations hereunder
are expressly conditioned on the satisfaction at or before the time of Closing hereunder, or at or
before such earlier time as may be expressly stated below, of each of the following conditions (any
one or more of which may be waived in writing in whole or in part by Buyer, at Buyer’s option):

3.1 Performance. Seller shall have performed, observed and complied with all
covenants, agreements and conditions required by this Agreement to be performed, observed and
complied with on its part prior to or as of the Closing hereunder.

3.2 Documents. Seller shall immediately make available to Buyer copies of all
documents in Seller’s actual possession or under Seller’s control which are listed on Exhibit H
attached hereto (collectively, the “Contracts”). Prior to the expiration of the Inspection
Period (as defined below), Buyer shall notify Seller and list those service contracts which Buyer
desires to assume as of the Closing (the “Approved Service Contracts”). Seller shall terminate any
service contracts which are not Approved Service Contracts, at Seller’s cost and expense. The
parties stipulate that any contract for property management services is not an Approved Service
Contract, and shall be terminated prior to Closing at Seller’s sole cost.

3.3 Inspection Period: Access.

3.3.1 During the Inspection Period, Buyer, its agents and representatives, shall be entitled
to review all zoning and other land use matters relating to the Property and to enter upon the
Property (as coordinated through Seller’s property manager), upon reasonable prior notice to
Seller, to (i) perform inspections, and tests of the Property, including surveys, Phase I
environmental studies, examinations and tests of all structural and mechanical systems within the
Building, so long as the tenants’ occupancy of the Property is not disturbed and so long as such
entry into tenant-occupied areas is done in accordance with the terms of such tenant lease and (ii)
conduct Tenant interviews provided however Seller shall have the right to be present at all such
interviews. Notwithstanding the foregoing, if Buyer wishes to engage in a Phase II environmental
study or any other environmental or other testing or sampling of any kind with respect to soils or
groundwater or other studies which would require test boring of or other intrusions into the
Property or the Building or which testing would otherwise damage or disturb any portion of the
Property or Building, Buyer shall obtain Seller’s prior written consent thereto, which consent may
be withheld in Seller’s sole discretion. To the extent Seller approves any such testing, Buyer
shall be responsible for, and shall dispose of, all such test samples in accordance with applicable
law at no cost or liability to Seller. Buyer shall repair any damage to the Property caused by any
such tests, investigations or studies and indemnify Seller from any and all liabilities, claims,
costs and expenses resulting therefrom and from Buyer’s entry upon the Property. The foregoing
indemnification shall survive Closing or the termination of this Agreement. If Buyer elects not to
proceed with Closing after its inspection of the Property, the Deposit shall be retained by Seller.

3.3.2 The term “Inspection Period”, as used herein, shall mean the period commencing on the
Date of this Agreement and continuing thereafter until 5:00 p.m. Pacific Time on the date that is
21 days after the date hereof.

3.4 Title. Seller shall deliver to Buyer immediately after the date hereof a current
Commitment for Title Insurance with respect to the Property issued by Commonwealth Land Title
Insurance Company whose address is Attention: Donald R. Hallman, Senior Vice President, 888 West
Sixth Street, 4th Floor, Los Angeles, CA 90017 (the “Title Company”), with copies of all
instruments listed as exceptions to title therein (collectively, the “Title Documents”). Seller
shall deliver within three (3) business days at Seller’s sole cost and expense the survey of the
Property which Seller obtained when Seller acquired the Property (the “Survey”). Buyer may elect to
have the Survey updated, at Buyer’s expense, in which case Buyer shall deliver a copy of the
updated Survey to Seller. Buyer shall have until the date which is 14 days after the date that
Seller delivers to Buyer all of the Title Documents and the Survey (the “Title Period”) to examine
the Title Documents and the Survey. If Buyer reasonably objects to any matters disclosed in the
Title Documents or Survey, Buyer shall, within the Title Period, notify Seller in writing (“Buyer’s
Notice”), specifying any reasonably objectionable matters. Seller shall use commercially reasonable
efforts to cure any such reasonably objectionable matters, or may arrange for title insurance to
cover any objectionable matter. The Closing Date shall be extended, if necessary, in order for
Seller to cure such objectionable matters, using reasonable diligence. If such cure cannot be
accomplished within thirty (30) days after the originally scheduled Closing Date, this Agreement
shall terminate and the Deposit shall be retained by Seller. Buyer shall, at its sole cost and
expense, obtain any endorsements required by Buyer. Seller shall pay for standard title insurance,
provided that Buyer pays for the cost of such endorsements, except for any endorsement ordered by
Seller to cover any matter affecting title which is the obligation of Seller, which endorsement, if
any, shall be paid for by Seller. On the Closing, the Title Company shall issue to Buyer a title
policy with such endorsements as described above (the “Title Policy”).

3.5 Estoppel Certificates. Seller shall make a commercially reasonable effort to
provide, not later than five (5) days prior to the Closing Date, that Buyer shall receive an
estoppel certificate (each, an “Estoppel Certificate”) in the form requested by Buyer from each
tenant at the Property. Seller will deliver to tenants a proposed Subordination, Non-Disturbance
and Attornment Agreement (“SNDA”) prepared by Buyer, and will make a commercially reasonable effort
to obtain an executed SNDA from each tenant. Seller agrees to deliver to Buyer any SNDA received by
Seller as soon as reasonably possible after receipt of such. It shall not be a condition to Closing
that any tenant execute and deliver an Estoppel Certificate or the SNDA.

	 	7.	 	Apportionments, Taxes,
Expenses.	 

7.1 Apportionments.

7.1.1 Transfer Taxes. Any transfer tax imposed by the City of Dallas, County of Dallas
or the State of Texas shall be paid by Seller.

7.1.2 Taxes and Utilities. All (i) real estate taxes, charges and assessments
affecting the Real Property and (iii) all charges for water, electricity, sewer, gas, and all other
utilities (collectively, “CAM Charges”) shall be prorated on a cash basis as of the date of Closing
to the extent paid directly by Seller and not paid directly to the taxing authorities by the
tenants under the Leases for the Real Property.

7.1.3 Rent/CAM Charges. Collected rent and monthly CAM Charges for the month of the
Closing shall be prorated on a cash basis as of the date of Closing. Delinquent rent and CAM
Charges for the month of the Closing shall be prorated on a per diem basis as of the date of the
Closing but only at such time that such delinquent rent or CAM Charges are received by either
Seller or Buyer. Delinquent rent and CAM Charges for the months prior to the Closing shall remain
the property of Seller. Payments received by Buyer from tenants from and after the date of the
Closing shall be applied first to rents and CAM Charges then due for the current period and then to
delinquent rents and CAM Charges for the month of the Closing and then to delinquent rents and CAM
Charges for months prior to the Closing Date. Buyer shall use reasonable efforts to collect
delinquent rents for the benefit of Seller, and shall cooperate with Seller in collection of any
delinquent amounts. Seller shall not be responsible for any underpayment of CAM Charges. If CAM
Charges are paid on an annual basis, then upon Buyer’s receipt of such payment Buyer shall promptly
deliver to Seller, such Seller’s pro rata share of such annual payment based upon the number of
days which Seller owned the Property for such year. Promptly following the end of the calendar
year, but in no event later than March 15, 2006, Seller and Buyer shall reprorate such CAM Charges
based upon actual bills and invoices received for such calendar year. Any reprorated items shall be
promptly paid to the party entitled thereto (provided, however, if such reprorations indicate that
CAM Charges were actually greater than charged to and/or reimbursed by the tenants, Buyer shall
collect such shortfall from the tenants before such payments are made).

7.1.4 Tenant Security Deposits. Buyer shall receive a credit for tenant security
deposits. Seller shall notify Escrow Agent prior to the Closing Date of the amount of the security
deposits. Seller shall cause any tenant security deposit in the form of a letter of credit to be
delivered to Escrow Agent prior to the Closing Date, along with such instruments as are necessary
to cause letters of credit to be transferred to the benefit of Buyer. If any letter of credit for a
security deposit is not transferred as of the Closing Date, Seller will deposit with Escrow Agent
an amount equal to the available credit under such letter of credit, and Buyer shall be entitled to
have such amount applied for the same purposes as the letter of credit, if such had been timely
assigned to Buyer. Upon assignment of any such letter of credit, the remaining balance in the
custody of Escrow Agent shall be returned to Seller.

7.1.5 Contracts. All costs and expenses with respect to any Approved Service
Contracts, including any new contracts entered into by Seller pursuant to the terms of Section
15.2.1, shall be prorated such that Seller shall be responsible for all such costs and expenses to
and including the day prior to the Closing, and Buyer shall be responsible for all such costs and
expenses for the day of Closing and all periods thereafter.

7.1.6 New Lease Expenses. All New Lease Expenses shall be prorated between the parties
as set forth in Section 15.2.2 below.

7.2 Expenses. Each party will pay all its own expenses incurred in connection with
this Agreement and the transactions contemplated hereby, including, without limitation, (1) all
costs and expenses stated herein to be borne by a party, and (2) all of their respective
accounting, legal and appraisal fees. Buyer shall pay at Closing (1) all recording charges incident
to the recording of the Deed, (2) all endorsements to the Title Policy except for endorsements for
which Seller is responsible hereunder, and (3) one-half of the fees, costs and expenses of Escrow
Agent. Seller shall pay at Closing one-half of the fees, costs and expenses of Escrow Agent, and
the cost of a standard Title Policy and any endorsements for which Seller is responsible hereunder.
Any other costs of the Closing shall be split between the parties in accordance with the custom of
Dallas County, Texas, unless otherwise specifically provided in this Agreement.

8. Damage or Destruction, Condemnation Insurance.

8.1 Condemnation. If at any time prior to the date of Closing greater than 5% of the
area of the Property is condemned or taken by eminent domain proceeding by any public authority,
then at Buyer’s option, to be exercised within 5 days’ notice of such taking, this Agreement shall
terminate, and the Deposit shall be refunded to Buyer, and except as expressly set forth herein,
neither party shall have any further liability or obligation to the other hereunder. If (a) Buyer
elects not to terminate this Agreement, and the Property had a condemnation action with respect to
5% or greater of its respective area, or (b) if less than 5% of the area of the Property is
affected, the parties shall proceed to the Closing without a reduction in the Purchase Price and
all condemnation proceeds paid or payable to Seller shall belong to Buyer and shall be paid over
and assigned to Buyer at Closing. Seller shall have no obligation to make any repairs to the
Property in the event of a condemnation.

8.2 Damage and Destruction. If, at any time prior to the date of Closing, a material
portion of the Property is destroyed or damaged as a result of fire or any other casualty
whatsoever, then at Buyer’s option, to be exercised within 5 days’ notice of such damage or
destruction, this Agreement shall terminate, the Deposit shall be returned to Buyer, and except as
expressly set forth herein, neither party shall have any further liability or obligation to the
other hereunder. For purposes hereof, the term “material” shall be deemed to be either (i) a damage
or destruction in excess of $1,000,000.00, (ii) any damage or destruction which is not covered by
Seller’s insurance, unless Seller agrees to pay for such uninsured damage, or (iii) any damage or
destruction which gives any tenants in the Building the right to terminate leases for more than 5%
of the rentable area of the Building. If less than a material portion of the Property is damaged or
destroyed, or if a material portion of the Property is damaged or destroyed and Buyer elects not to
terminate this Agreement, the parties shall proceed to the Closing without reduction in the
Purchase Price other than by the amount of the deductible under Seller’s insurance policy and all
insurance proceeds paid or payable to Seller shall belong to Buyer and shall be paid over and
assigned to Buyer at Closing; provided, however, any rental abatement or business interruption
proceeds shall be prorated in accordance with Section 7.1.2 above when such proceeds are paid.
Seller shall have no obligation to make any repairs to the Property in the event of a damage or
destruction.

9. Liquidated Damages. IN THE EVENT THE CLOSING AND THE CONSUMMATION OF THE
TRANSACTION HEREIN CONTEMPLATED DO NOT OCCUR AS HEREIN PROVIDED BY REASON OF ANY BREACH OF BUYER,
BUYER AND SELLER AGREE THAT IT WOULD BE IMPRACTICAL AND EXTREMELY DIFFICULT TO ESTIMATE THE DAMAGES
WHICH SELLER MAY SUFFER. THEREFORE BUYER AND SELLER DO HEREBY AGREE THAT A REASONABLE ESTIMATE OF
THE TOTAL NET DETRIMENT THAT SELLER WOULD SUFFER IN THE EVENT THAT BUYER BREACHES THIS AGREEMENT
AND FAILS TO COMPLETE THE PURCHASE OF THE PROPERTY IS AND SHALL BE, AS SELLER’S SOLE AND EXCLUSIVE
REMEDY (WHETHER AT LAW OR IN EQUITY), TO KEEP THE DEPOSIT (WHICH INCLUDES ANY ACCRUED INTEREST
THEREON). THE DEPOSIT SHALL BE THE FULL, AGREED AND LIQUIDATED DAMAGES FOR THE BREACH OF THIS
AGREEMENT BY BUYER, ALL OTHER CLAIMS TO DAMAGES OR OTHER REMEDIES FOR BUYER’S BREACH OF ITS
OBLIGATION TO PROCEED WITH CLOSING ARE EXPRESSLY WAIVED BY SELLER. UPON A BREACH BY BUYER, UNLESS
OTHERWISE SPECIFIED, THIS AGREEMENT SHALL TERMINATE AND NEITHER PARTY SHALL HAVE ANY FURTHER RIGHTS
OR OBLIGATIONS HEREUNDER, EACH TO THE OTHER, EXCEPT FOR THE RIGHT OF SELLER TO THE DEPOSIT AS
LIQUIDATED DAMAGES FROM BUYER.

DEFAULT IN SELLER’S OBLIGATIONS HEREUNDER, BUYER SHALL BE ENTITLED, AS ITS SOLE REMEDY FOR SUCH
DEFAULT, (i) TO TERMINATE THIS AGREEMENT AND RECEIVE THE RETURN OF THE DEPOSIT AND, IF SUCH DEFAULT

this Agreement, Seller agrees as follows:

15.1 Maintenance of Real Property. Seller shall cause the Property to be operated
in the ordinary and usual course of business and consistent with the past practice, reasonable
wear and tear excepted.

15.2 Contracts/Leases. From and after the expiration of the Inspection Period, Seller
will not amend, terminate, waive any default under, or grant concessions regarding any Approved
Service Contract or Leases or enter into any new service contract or tenant lease, that will be an
obligation affecting the Property or binding on the Buyer after Closing, except as otherwise
provided hereinbelow.

15.2.1 Contracts. Seller shall not, without Buyer’s prior consent in each instance
(which consent shall not be unreasonably withheld, conditioned or delayed), enter into any new
contracts affecting the Property, except for (i) agreements which are terminable on or prior to
Closing, which agreements shall be terminated by Seller on or before Closing, and (ii) Lease
Amendments and New Leases as provided in Section 15.2.2. Buyer shall advise Seller in writing
whether Buyer approves or disapproves any such new agreements, modifications or terminations
requiring its approval within three (3) business days after Buyer’s receipt of the proposed
document. If Buyer fails to notify Seller within such period, Buyer shall be deemed to have
approved the proposed document. All new agreements approved or deemed approved by Buyer under this
Section 15.2.1 (other than New Leases and Lease Amendments) and shall be assigned to and assumed by
Buyer upon Closing as an Approved Service Contract.

15.2.2 New Leases and Lease Amendments. If Seller desires to enter into any new lease
affecting the Property (each, a “New Lease”) or any termination, amendment, modification, expansion
or renewal of an existing Lease (each, a “Lease Amendment”), after the date of this Agreement but
prior to Closing, Seller shall provide Buyer with a copy of the proposed New Lease or Lease
Amendment and a copy of Seller’s anticipated improvement costs, tenant improvement allowances,
brokerage commissions and out-of-pocket costs and expenses in connection with the New Lease or
Lease Amendment and all information in Seller’s possession regarding the proposed new tenant for
Buyer’s review and approval, which approval may be withheld in Buyer’s reasonable discretion. Buyer
shall advise Seller, in writing, whether Buyer approves or disapproves such proposed New Lease or
Lease Amendment within three (3) business days after Buyer’s receipt of the proposed New Lease or
Lease Amendment; provided, however, if Buyer fails to notify Seller within such three (3) business
day period, Buyer shall be deemed to have approved the proposed transaction. If Buyer reasonably
disapproves of the proposed New Lease or Lease Amendment, Seller shall not enter into such New
Lease or Lease Amendment. Upon the Closing, Buyer shall assume and be responsible for (and to the
extent previously paid by Seller, reimburse Seller on the date of Closing for) a prorata portion of
any and all improvement costs, tenant improvement allowances, brokerage commissions and
out-of-pocket costs and expenses actually paid or incurred by Seller (collectively the “New Lease
Expenses”) arising out of or in connection with those New Leases and Lease Amendments entered into
by Seller pursuant to the foregoing provisions of this Section 15.2.2; such pro-rata portion(s) for
which Buyer shall be responsible shall equal the product of (i) the New Lease Expenses multiplied
by (ii) a fraction, the numerator of which is the number of months of the lease term of the New
Lease (or the number of months of the term of any exercised extension period provided by any Lease
Amendment, as applicable) remaining as of the date of Closing, and the denominator of which is the
total number of months of such lease term (or exercised extension period, as applicable). Seller
shall be responsible for the remaining pro-rata portion of the New Lease Expenses. Upon Closing,
Seller shall assign (and Buyer shall accept such assignment of) the New Lease(s) and Lease
Amendment(s) which shall be deemed to be part of the Leases hereunder. Seller will provide Buyer
with copies of any notice of default sent to or received from tenants at the Property after the
date hereof, copies of any correspondence from any tenant in which such tenant indicates that it
intends to discontinue its operations at the Property or to re-negotiate the terms of its lease at
the Property, and any notices of the filing of any action in bankruptcy or any assignment for the
benefit of creditors with respect to any tenant at the Property. The parties shall calculate and
agree upon the amount of free rent owed to any tenant identified on Exhibit “K” and Seller
shall give Buyer a credit at Closing for such free rent. Seller shall be solely responsible for
“Seller’s Lease Obligations” as set forth on Exhibit “L” attached hereto, and shall either
pay such obligations at or prior to Closing, or give Buyer a credit for the same at Closing to the
extent that Seller’s Lease Obligations remain unpaid and outstanding as of the Closing Date,
whereupon Buyer shall be obligated to pay all Seller’s Lease Obligations after Closing for which
Buyer has received a credit. In the event that it is determined that there are additional
outstanding leasing commissions or unpaid tenant improvement costs for Leases executed prior to the
date hereof other than those shown on Exhibit “L” or rent concessions owed to any tenant
except as described on Exhibit “K”, Buyer shall receive a credit for any such amounts at Closing.

15.2.3 Insurance. Seller shall, at its sole cost and expense, keep and maintain in
full force and effect through the Closing, Seller’s existing insurance coverage with respect to the
Property.

lenders (collectively referred to herein as “Representatives”), or prospective investors in the
Property who have a business relationship with Buyer (“Prospective Investors”) who need to know
such information for the purpose of evaluating or financing its acquisition of the Property, or for
the purpose of evaluating an investment in the Property. Prior to any disclosure to its
Representatives, however, Buyer shall inform its Representatives of the confidential nature of the
evaluation material, and Buyer’s Representatives shall agree to be bound by this statement of
confidentiality and not to disclose such information to any other person. Prior to any disclosure
to Prospective Investors, Buyer shall inform them of the confidential nature of the evaluation
material, shall not be obligated to cause them to agree to be bound by this statement of
confidentiality and not to disclose such information to any other person. In the event that Buyer
or any of its Representatives become legally compelled to disclose any of the Evaluation Material,
Buyer and its Representatives shall provide Seller with prompt prior written notice of such
requirements so that Seller may seek a protective order or other appropriate remedy and/or waive
compliance with the terms of this statement of confidentiality. In the event that Buyer fails to
complete the acquisition of the Property, Buyer will make a commercially reasonable effort to
assure that Buyer and its Representatives will promptly return to Seller copies of all of the
Evaluation Material which has been provided to Buyer by Seller and Buyer will make a commercially
reasonable effort to assure that Buyer and its Representatives will destroy all copies of any
analysis, compilations, studies or other documents prepared by Buyer or for its use containing or
reflecting any Evaluation Material.

AND JOINT ESCROW INSTRUCTIONS

This FIRST AMENDMENT TO PURCHASE AND SALE AGREEMENT AND JOINT ESCROW INSTRUCTIONS (this
“Amendment”) dated as of December 23, 2005, is made by and between SP REVERCHON PROPERTIES,
LP, a Delaware limited partnership (“Seller”) and NNN 3500 Maple, LLC, a Delaware limited
liability company (“Buyer”), as successor-in-interest to TRIPLE NET PROPERTIES, LLC, a Virginia

RECITALS

A. Seller and Buyer entered into that certain Purchase and Sale Agreement and Joint Escrow
Instructions, dated as of October 21, 2005 (the “Agreement”), in connection with the sale
of that certain property located in the City of Dallas, County of Dallas or the State of Texas,
which is commonly known by the street address of 3500 Maple, Dallas, Texas, as more particularly
described in the Agreement. Capitalized terms used herein and not otherwise defined shall have the
meaning ascribed to them in the Agreement.

B. Buyer and Seller now desire to modify the Agreement.

C. The Agreement has expired and the Seller and Buyer desire to reinstate and amend the
Agreement as hereinafter provided.

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, Seller and Buyer do hereby agree that the Agreement is hereby reinstated and
amended as follows:

1. Section 2 of the Agreement is hereby amended by deleting the reference to “Sixty Seven
Million Dollars U.S. ($67,000,000.00)” and replacing it with “Sixty Six Million Five Hundred
Thousand Dollars U.S. ($66,500,000.00)”.

2. Section 6.1 of the Agreement is hereby deleted in its entirety and replaced with the
following”:

“The closing under this Agreement (the “Closing”) shall take place on December 23, 2005
(“Closing Date”). Buyer shall have the right to elect to extend the Closing Date to a date
not later than December 27, 2005, as set forth in this Section 6.1. If Buyer elects to
extend the Closing Date, Buyer shall, on or prior to the Closing Date, so notify Seller in
writing, and shall deliver to Seller an additional amount of Seven Hundred Fifty Thousand
Dollars U.S. (U.S. $750,000.00) (the “Third Deposit”). The Third Deposit shall be part of
the Deposit and shall be non-refundable to Buyer except in the event of a default by Seller
which results in the termination of this Agreement, or in the event of certain casualty or
condemnation events as set forth herein.”

3. A new Section 17.13 is added to the Agreement, as follows:

“17.13 Section 3 — 14 Audit.

requirements imposed upon Buyer. Seller’s cooperation is limited to (i) making its books and
records for the calendar year 2004 available for inspection during normal business hours
upon two business days prior notice and (ii) delivering a “representation letter” in the
form attached hereto as Exhibit “M”. This Section 17.13 shall survive for the six (6) month
period after the Close of Escrow.”

4. A new Exhibit M is added to the Agreement in the form attached hereto as Exhibit A.

5. All other terms and conditions of the Agreement not specifically modified or
supplemented by this Amendment shall remain unchanged and in full force and effect, and the
Agreement, as supplemented by this Amendment, is hereby ratified and confirmed. This Amendment (a)
shall be governed, construed and enforced under the laws of the State of Texas, (b) contains the
entire understanding of the parties with respect to the provisions of the Agreement amended and
supplemented hereby, (c) may not be modified except by a writing signed by both parties and (d) and
shall be binding upon and inure to the benefit of Seller and Buyer, and their respective successors
and permitted assigns.

6. In the event of any conflict between the terms of the Agreement and the terms of this
Amendment, the terms of this Amendment shall control.

7. The parties agree that this Amendment may be transmitted between them by facsimile machine
and the parties intend that a faxed Amendment containing either the original and/or copies of the
signature of all parties shall constitute a binding Amendment. This Amendment may be executed in
any number of counterparts, each of which shall be deemed to be an original agreement and all of
which when taken together shall be deemed to be one and the same agreement.
