adopted a Long-term Incentive Plan, effective July 16, 2004; and

     WHEREAS, it is desirable that the Plan be restated and amended, effective                     ,

Units in Bois d’Arc Energy, LLC awarded under the Plan were converted into options to acquire

Energy, LLC awarded under the Plan were converted into restricted shares of common stock of the
Company; and

     WHEREAS, the Company desires to set forth the amended terms of the Plan, under which the Board

the Board will have authority to select employees, consultants and independent contractors to

times of receipt, to determine the types of awards and the number of Shares covered by the awards,
to establish the terms, conditions, performance criteria, restrictions, and other provisions of
such awards, to determine the number and value of Performance Shares awarded and earned, and to
cancel or suspend awards. In making such award determinations, the Board may take into account the
nature of services rendered by the employee, consultant or independent contractor, his or her

-3-

 

made pursuant to the Plan, and to make all other determinations that may be necessary or advisable
for the administration of the Plan. The Board may, from time to time, delegate its authority to
manage and control the operation and administration of the Plan to the Committee. In such case,
all references herein to the “Board” shall be deemed to refer to the “Committee.”

     A majority of the Committee shall constitute a quorum, and the acts of a majority of the
members present at any meeting at which a quorum is present, or acts approved in writing by all
members of the Committee, shall be the acts of the Committee, unless provisions to the contrary are
embodied in the Company’s Bylaws or resolutions duly adopted by the Board. All actions taken and
decisions and determinations made by the Board or the Committee pursuant to the Plan shall be
binding and conclusive on all persons interested in the Plan. No member of the Board or the
Committee shall be liable for any action or determination taken or made in good faith with respect
to the Plan.

     Notwithstanding the foregoing, all authority to exercise discretion with respect to the
participation in the Plan of persons who are “officers” within the meaning of the applicable
Securities and Exchange Commission rules relating to Section 16 of the Securities Exchange Act of
1934, as amended, and/or directors of the Company, or the timing, pricing and amounts of awards
granted under the Plan to such officers and directors, shall be vested in (a) the Board, or (b) the
Committee, if consisting of two or more directors each of whom is a non-employee director within
the meaning ascribed to such term in Rule 16b-3 promulgated under the Securities Exchange Act of
1934, as amended, or within any successor definition or any successor rule.

          5. Participation. (a) Employees, Consultants and Independent Contractors.
The Board shall determine and designate, from time to time, the key executives and managerial
employees, consultants or independent contractors of the Company and/or its Subsidiaries who may
receive awards under the Plan. In the discretion of the Board, an eligible employee, consultant or
independent contractor may be awarded Options, Restricted Stock or Performance Shares or any
combination thereof, and more than one award may be granted to a Participant. Except as otherwise
agreed to by the Company and the Participant, any award under the Plan shall not affect any
previous award to the Participant under the Plan or any other plan maintained by the Company or its
Subsidiaries.

          (b) Non-employee Directors. Each Non-employee Director shall be granted without
further action by the Board a Non-Qualified Option to purchase 5,000 Shares at the close of
business of each annual meeting of the stockholders of the Company. An individual who is first
elected and commences serving as a Non-employee Director shall also be granted without further
action by the Board a Non-Qualified Option for 5,000 Shares on the date of such election as a
Director.

     The Non-Qualified Options shall be fully vested and exercisable by each Non-employee Director
after the Director has completed twelve (12) continuous months of service as a member of the Board
after the Option Date (unless his service terminates during such period by reason of Retirement,
death or Disability, when the awards shall become 100% vested). The term of each Non-Qualified
Option shall be five (5) years from the Option Date, and the exercise price shall be 100% of the
Fair Market Value of the Stock as of the Option Date. The full purchase price of each

-4-

 

Share purchased upon exercise of a Non-Qualified Option shall be paid in the manner set forth in
Article III, paragraph 3 hereof. All outstanding options become 100% vested and exercisable if
service as a member of the Board terminates by reason of death, Disability or Retirement.

     6. Stock Subject to the Plan. (a) Awards to Employees, Consultants and Independent
Contractors. Subject to the provisions of paragraph I.10, the number of Shares
available under the Plan for awards to employees, consultants and independent contractors shall not
exceed 6,179,775 shares of common stock, in the aggregate. In addition, the aggregate number of
Shares for which awards (other than Incentive Stock Options) may be granted shall be increased, if
necessary, as of the first day of each fiscal year commencing January 1, 2006, so that the number
of Shares available under this Plan shall be no less than eleven percent (11%) of the number of
Shares outstanding as of the close of business on the last day of the preceding fiscal year. If,
for any reason, any award under the Plan otherwise distributable in Shares, or any portion of the
award, shall expire, terminate or be forfeited or canceled, or be settled in cash pursuant to the
terms of the Plan and, therefore, any such Shares are no longer distributable under the award, such
Shares shall again be available for award under the Plan.

     (b) Awards to Non-Employee Directors. Subject to the provisions of paragraph I.10, the
number of Shares available under the Plan for awards to Non-employee Directors shall not
exceed three hundred fifty thousand (350,000) Shares. If, for any reason, any Option award to a
Non-employee Director under the Plan or any portion of such award, shall expire, terminate or be
forfeited or canceled, or be settled in cash pursuant to the terms of the Plan and, therefore, any
such Shares are no longer distributable under the award, such Shares shall again be available for
award to Non-employee Directors under the Plan.

     (c) Annual Limit on Grants to Employees. Subject to the provisions of paragraph I.10,
the number of shares of Stock with respect to which Options under the Plan may be granted in any
calendar year to any employee shall not exceed 1,000,000 shares.

     7. Compliance With Applicable Laws and Withholding of Taxes. Notwithstanding any
other provision of the Plan, the Company shall have no liability to issue any Stock under the Plan
unless such issuance would comply with all applicable laws and the applicable requirements of any
securities exchange or similar authority. Prior to the issuance of any Stock under the Plan, the
Company may require a written statement that the recipient is acquiring the Stock for investment
and not for the purpose or with the intention of distributing as amended, the Stock. All awards
and payments under the Plan to employees are subject to withholding of all applicable taxes, which
withholding obligations may be satisfied, with the consent of the Board, through the surrender of
Shares which the Participant already owns, or to which a Participant is otherwise entitled under
the Plan.

     Upon termination of the Restricted Period with respect to an award of Restricted Stock (or
such earlier time, if any, as an election is made by the Participant under Code Section 83(b), or
any successor provisions thereto, to include the value of such Stock in taxable income), the
Company shall have the right to require the Participant to pay to the Company the amount of taxes
that the Company is required to withhold with respect to such Stock or, in lieu thereof, to retain
or sell without notice a sufficient number of Shares held by it to cover the amount required

-5-

 

to be withheld. The Company shall have the right to deduct from all distributions paid with respect
to a Restricted Stock award the amount of taxes that the Company is required to withhold with
respect to such distribution payments, if any.

     8. Transferability. Incentive Stock Options, Performance Shares, and, during the
period of restriction, Restricted Shares awarded under the Plan are not transferable except as
designated by the Participant by will or by the laws of descent and distribution. Incentive Stock
Options may be exercised during the lifetime of the Participant only by the Participant or his
guardian or legal representative. If expressly permitted by the terms of the Option agreement,
Non-Qualified Options may be transferred by a Participant to Permitted Transferees, provided that
there is not any consideration for the transfer.

     9. Employment and Stockholder Status. The Plan does not constitute a contract of
employment, and selection as a Participant will not give any employee the right to be retained in
the employ of the Company or any Subsidiary. The Plan does not constitute or serve as evidence of
an agreement or understanding, express or implied, that the Company will retain a consultant,
independent contractor or Director for any period of time. Subject to the provisions of paragraph
IV.3(a), no award under the Plan shall confer upon the holder thereof any right as a stockholder
prior to the date on which he fulfills all service requirements and other conditions for receipt of
Stock. If the redistribution of Shares is restricted pursuant to paragraph I.8,
certificates representing such Shares may bear a legend referring to such restrictions.

     10. Adjustments to Number and Kind of Securities Subject to the Plan. In the event of
any change in the outstanding Stock of the Company by reason of any recapitalization,
merger, consolidation, combination, exchange of shares, or other similar change, the aggregate
number of Shares with respect to which awards may be made under the Plan, the terms and the number
of Shares under any outstanding Options, Performance Shares, or Restricted Shares, and the purchase
price of a Share under Options, may be equitably adjusted by the Board in its sole discretion. In
addition, the Board may, in its sole discretion, make appropriate adjustment as to the kind of
shares or other securities deliverable with respect to outstanding awards under the Plan.

     11. Agreement With Company; Market Stand-Off. At the time of any awards under the
Plan, the Board will require a Participant to enter into an agreement with the Company in a form
specified by the Board, agreeing to the terms and conditions of the Plan and to such additional
terms and conditions, not inconsistent with the Plan, as the Board may, in its sole discretion,
prescribe. For such period and on such terms as the managing underwriter may request in connection
with the public offering of Company securities, the Participants shall not (x) offer, pledge, sell,
contract to sell, sell any portion or contract to purchase, purchase any option or contract to
sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly
or indirectly, any Stock or any securities convertible into or exercisable or exchangeable for
Stock (including, without limitation, shares of common stock or securities convertible into or
exercisable or exchangeable for Stock which may be deemed to be beneficially owned by the
Participant in accordance with the rules and regulations of the Securities and Exchange Commission)
(collectively, “Company Securities”) or (y) enter into any swap or other arrangement that transfers
all or a portion of the economic consequences associated with the ownership of any Company
Securities (regardless of whether any of the transactions described in

-6-

 

clause (x) or (y) is to be settled by the delivery of Company Securities, in cash or otherwise),
provided that the Company notifies the Participant of the applicability of the lock-up. The
Participant shall enter into an agreement acknowledging the lock-up if requested by the Company or
such underwriter.

     12. Amendment and Termination of Plan. The Board may at any time and in any way
amend, suspend or terminate the Plan; provided, however, that no amendment of the Plan shall be
made without shareholder approval if shareholder approval is required by law, regulations, or stock
exchange rule. No amendment, suspension or termination of the Plan shall alter or impair any
Option, Restricted Stock or Performance Share previously awarded under the Plan without the consent
of the holder thereof.

13. Business Combinations. For the purposes of the Plan, a “Change in Control” shall mean:

	 	(a)  	during any period of two consecutive years, individuals who at
the beginning of such period constituted the Board cease for any reason to
constitute a majority thereof (unless the election, or nomination for election
by holders of the Company’s stock (“Company Equity”), of such member of the
Board was approved by a vote of at least two-thirds (2/3) of the members of the
Board then still in office who either were members of the Board at the
beginning of such period or whose election or nomination for election was
previously so approved);
	 
	 	(b)  	a person, other than an “Excluded Person” as defined herein,
including a “group” as defined in Paragraph 13(d)(3) of the Securities Exchange
Act of 1934, becomes the beneficial owner of shares of any class of the Company
Equity having 25% or more of the total number of votes that may be cast for the
election of members of the Board; or
	 
	 	(c)  	consummation of a merger or other business combination of the
Company with or into another corporation pursuant to which the Company does not
survive or survives only as a subsidiary of another entity, the sale or other
disposition of all or substantially all of the assets of the Company to another
person or entity, or any combination of the foregoing;

provided, however, that a Change in Control will not include (A) any Financing Transaction
(as defined in the Operating Agreement of Bois d’Arc Energy, LLC, dated as of July 16, 2004)
and any transaction entered into in connection therewith, (B) any reorganization, merger,
consolidation, sale, lease, exchange or similar transaction which involves solely the
Company and one or more entities wholly-owned, directly or indirectly, by the Company
immediately prior to such event, or (C) the consummation of any transaction or series of
integrated transactions immediately following which the record holders of the voting Company
Equity immediately prior to such transaction or series of transactions continue to hold 50%
or more of the voting Company Equity of (i) any entity that owns, directly or indirectly,
the Company Equity, (ii) any entity with which the Company has merged, or (iii) any entity
that owns an entity with which the Company has merged. For purposes hereof, (i) an
“Excluded Person” shall mean an original member of the Company or their affiliates, and (ii)
a person will be deemed to be the beneficial owner of any voting securities of the Company
which it would be

-7-

 

considered to beneficially own under Securities and Exchange Commission Rule 13d-3 (or any
similar or superseding statute or rule from time to time in effect). In the event of a
Change in Control, all outstanding Stock Options, Restricted Stock and Performance Shares
will automatically become exercisable and vested.

II. INCENTIVE STOCK OPTIONS

     1. Definition. The award of an Incentive Stock Option under the Plan entitles the
Participant to purchase shares of Stock at a price fixed at the time the option is awarded, subject
to the following terms of this Part II.

     2. Eligibility. The Committee shall designate the Participants to whom Incentive
Stock Options, as described in section 422A(b) of the Code or any successor section thereto, are to
be awarded under the Plan and shall determine the number of option shares to be offered to each of
them. Incentive Stock Options shall be awarded only to key employees of the Company, and no
Non-employee Director shall be eligible to receive an award of an Incentive Stock Option. In no
event shall the aggregate Fair Market Value (determined at the time the option is awarded) of Stock
with respect to which Incentive Stock Options are exercisable for the first time by an individual
during any calendar year (under all plans of the Company and all Related Companies) exceed
$100,000.

     3. Price. The purchase price of a share of Stock under each Incentive Stock Option
shall be determined by the Committee, provided, however, that in no event shall such price be less
than the greater of (a) 100% of the Fair Market Value of a share of Stock as of the Option Date (or
110% of such Fair Market Value if the holder of the Incentive Stock Option owns stock possessing
more than 10% of the combined voting power of all classes of stock of the Company or any Related
Company) or (b) the par value of a share of Stock on such date. Participants may elect to pay the
purchase price of shares of Stock purchased upon the exercise of Incentive Stock Options in cash or
through tendering, either through actual delivery or attestation, of shares of Stock (valued at
Fair Market Value as of the day of exercise) owned by the Participant, or any combination thereof,
equivalent to the purchase price of such Incentive Stock Options. As soon as practicable
thereafter, a certificate representing the shares so purchased shall be delivered to the person
entitled thereto. Any Shares that are tendered must have been held by the Participant for at least
six (6) months prior to their tender or have been purchased on the open market.

     4. Exercise. No Incentive Stock Option may be exercised by a Participant after the
Expiration Date (as defined in paragraph II.5 below) applicable to that option. Each Option shall
become and be exercisable at such time or times and during such period or periods, in full or in
such installments as may be determined by the Committee at the Option Date.

Option or any portion thereof awarded to a Participant under the Plan means the earliest of:

	 	(a)  	the date that is 10 years after the date on which the Incentive
Stock Option is awarded;

-8-

 

	 	(b)  	the date established by the Committee at the time of the award;
	 
	 	(c)  	the date that is one year after the Participant’s employment
with the Company and all Related Companies is terminated because of death or
permanent and total disability; as defined in Code Section 22(e)(3); or
	 
	 	(d)  	the date that is three months after the date the Participant’s
employment with the Company and all Related Companies is terminated for reasons
other than death or permanent and total disability.

III. NON-QUALIFIED OPTIONS

     1. Definition. The award of a Non-Qualified Option under the Plan entitles the
Participant to purchase Stock at a price fixed at the time the option is awarded, subject to the
following terms of this Part II.

     2. Eligibility. The Board shall designate the Participants to whom Non-Qualified
Options are to be awarded under the Plan and shall determine the number of Shares to be awarded to
each of them. No Non-employee Director shall be eligible to receive an award of a Non-Qualified
Option except to the extent granted pursuant to the formula set forth in Paragraph I.5(b) above.

     3. Price. The purchase price of a Share under each Non-Qualified Option shall be
determined by the Board; provided, however, that in no event shall such price be less than 25% of
the Fair Market Value of a Share as of the Option Date. Participants may elect to pay the purchase
price of shares of Stock purchased upon the exercise of Non-Qualified Stock Options by tendering,
either through actual delivery of shares of Stock or though attestation, shares of Stock (valued at
Fair Market Value as of the day of exercise) owned by the Participant, or any combination thereof,
equivalent to the purchase price of such Non-Qualified Stock Options. Any Shares that are tendered
must have been held by the Participant for at least six (6) months prior to their tender or have
been purchased on the open market. Stock acquired pursuant to the exercise of a Non-Qualified
Option shall be subject to such conditions, restrictions and contingencies as the Board may
establish in the award agreement. If the Company shall have a class of its Stock registered
pursuant to Section 12 of the Securities Exchange Act of 1934, as amended, an option holder may
also make payment at the time of exercise of a Non-Qualified Stock Option by delivering to the
Company a properly executed exercise notice together with irrevocable instructions to a broker
approved by the Company, that upon such broker’s sale of Shares with respect to which such option
is exercised, it is to deliver promptly to the Company the amount of sale proceeds necessary to
satisfy the option exercise price and any required withholding taxes.

     4. Exercise. No Non-Qualified Option may be exercised by a Participant after the
Expiration Date applicable to that option. Unless otherwise specified herein, each Option shall
become and be exercisable at such time or times and during such period or periods, in full or in
such installments as may be determined by the Board at the Option Date.

-9-

 

     5. Option Expiration Date. The “Expiration Date” with respect to a Non-Qualified
Option or any portion thereof awarded to a Participant under the Plan means the earliest of:

	 	(a)  	the date established by the Board at the time of the award or set forth in
paragraph I.5(b), as applicable;
	 
	 	(c)  	the date that is three months after the employee Participant’s employment with
the Company and all Subsidiaries or the consultant, independent contractor or
Non-employee Director Participant’s service is terminated for reasons other than
Retirement or death; or
	 
	 	(d)  	the date that is three years after the date the employee Participant’s
employment with the Company and all Subsidiaries or the consultant, independent
contractor or Non-employee Director Participant’s service is terminated by reason of
Retirement or death.

IV. RESTRICTED STOCK

     1. Definition. Restricted Stock awards are grants of Shares to Participants, the
vesting of which is subject to a required period of employment and any other conditions established
by the Board or by the terms of this Plan.

     2. Eligibility. The Board shall designate the Participants to whom Restricted Stock
is to be awarded and the number of Shares that are subject to the award.

     3. Terms and Conditions of Awards. All Restricted Stock awarded to Participants under
the Plan shall be subject to the following terms and conditions and to such other terms and
conditions, not inconsistent with the Plan, as shall be prescribed by the Board in its sole
discretion and as shall be contained in the agreement referred to in paragraph I.11.

	 	(a)  	Restricted Stock awarded to Participants may not be sold, assigned,
transferred, pledged or otherwise encumbered, except as hereinafter provided, for a
period of ten years or such shorter period as the Board may determine, but no less than
three years, after the time of the award of such Stock (the “Restricted Period”). Such
restrictions shall lapse as to the Restricted Stock in accordance with the time(s) and
number(s) of Shares as to which the Restricted Period expires, as set forth in the
Agreement with the Participant. Except for such restrictions, the Participant as owner
of such Stock shall have all the rights of a stockholder, including but not limited to
the right to receive all dividends on such Stock.
	 
	 	(b)  	The Board may in its discretion, at any time after the date of the award of
Restricted Stock, adjust the length of the Restricted Period to account for individual
circumstances of a Participant or group of Participants, but in no case shall the
length of the Restricted Period be less than one year.

-10-

 

	 	(c)  	Except as otherwise determined by the Board in its sole discretion, a
Participant whose employment or service with the Company and all Subsidiaries
terminates prior to the end of the Restricted Period for any reason shall forfeit all
Restricted Stock remaining subject to any outstanding Restricted Stock award which have
not then vested in accordance with the agreement entered into under paragraph I.11.
	 
	 	(d)  	Each certificate issued in respect of Restricted Stock awarded under the Plan
shall be registered in the name of the Participant and, at the discretion of the Board,
each such certificate may be deposited with the Company or in a bank designated by the
Board. Each such certificate shall bear the following (or a similar) legend:
	 
	 	   	“The transferability of this certificate and the Shares represented hereby are
subject to the terms and conditions (including forfeiture) contained in the BOIS
D’ARC ENERGY, INC. Long-term Incentive Plan and an agreement entered into between
the registered owner and BOIS D’ARC ENERGY, INC.. A copy of such plan and agreement
is on file in the office of the Secretary of BOIS D’ARC ENERGY, INC., 600 Travis,
Suite 6275, Houston, TX 77022, or if the Company changes its principal office, at
the address of such new principal office.”
	 
	 	(e)  	As the Restricted Period for Restricted Stock expires and such restrictions
lapse, such Restricted Stock shall be held by a Participant (or his or her legal
representative, beneficiary or heir) free of all restrictions imposed by the Plan and
the award agreement. Such Shares shall nevertheless continue to be subject to any
restriction imposed under applicable securities laws.

V. DEFERRED STOCK AND PERFORMANCE SHARES

     1. Definition. A “Deferred Stock” Award is the grant of a right to receive Stock in
the future. Performance Shares are awards to Participants who may receive value for the Shares at
the end of a Performance Period. The number of Shares earned, and value received for them, will be
contingent on the degree to which the performance measures established at the time of the initial
award are met. The term “Performance Shares” as used in Parts I through IV of the Plan shall be
deemed to include both Deferred Stock and Performance Shares.

     2. Eligibility. The Board shall designate the Participants to whom Deferred Stock or
Performance Shares are to be awarded, and the number of Shares to be the subject of such awards.
No Non-employee Director shall be eligible to receive an award of a Performance Share.

     3. Terms and Conditions of Awards. For each Participant, the Board will determine the
timing of awards; the number of Deferred Stock or Performance Shares awarded; the value of
Performance Shares; which may be stated either in cash or in Stock; the performance measures used
for determining whether the Performance Shares are earned; the performance period during which the
performance measures will apply; the relationship between the level of achievement of the
performance measures and the degree to which Performance Shares are earned; whether, during or
after the performance period, any revision to the performance measures or performance period should
be made to reflect significant events or changes that occur during the performance

-11-

 

period; the number of earned Performance Shares that will be paid in cash and/or Stock.; and
whether any dividends or dividend equivalents will be paid on Deferred Stock, either currently or
on a deferred basis.

     4. Payment. The Board will compare the actual performance to the performance measures
established for the performance period and determine the number of Performance Shares to be paid
and their value. Payment for Performance Shares earned shall be wholly in cash, wholly in Stock or
in a combination of the two, in a lump sum or installments, and subject to vesting requirements and
such other conditions as the Board shall determine. The Board will determine the number of earned
Shares to be paid in cash and the number to be paid in Stock. For Performance Shares awarded in
Stock, one Share will be paid for each Share earned, or cash will be paid for each Share earned
equal to either (a) the Fair Market Value of a Share at the end of the Performance Period or (b)
the Fair Market Value of a Share averaged for a number of days determined by the Board. For
Performance Shares awarded in cash, the value of each Share earned will be paid in its initial cash
value, or Shares will be distributed based on the cash value of the Shares earned divided by (a)
the Fair Market Value of a Share at the end of the Performance Period or (b) the Fair Market Value
of a Share averaged for a number of days determined by the Board.

     5. Retirement, Death or Termination. A Participant whose employment or service with
the Company and all Subsidiaries terminates during a performance period because of Retirement or
death shall be entitled to the prorated value of earned Performance Shares, issued with respect to
that performance period, at the conclusion of the performance period based on the ratio of the
months of employment or service during the period to the total months of the performance period.
If a Participant’s employment or service with the Company and all Subsidiaries terminates during a
performance period for any reason other than Retirement or death, the Performance Shares issued
with respect to that performance period will be forfeited on the date such Participant’s employment
or service terminates. Notwithstanding the foregoing provisions of this Part IV, if a
Participant’s employment or service with the Company and all Subsidiaries terminates before the end
of the Performance Period with respect to any Performance Shares awarded to him, the Board may
determine that the Participant will be entitled to receive all or any portion of the Shares that he
or she would otherwise receive, and may accelerate the determination and payment of the value of
such Shares or make such other adjustments as the Board, in its sole discretion, deems desirable.

JPMORGAN CHASE TOWER

LEASE AGREEMENT

     THIS LEASE AGREEMENT (this “Lease”) is made and entered into by and between TEXAS
TOWER LIMITED, a Texas limited partnership (“Landlord”), and BOIS D’ARC ENERGY LLC, a
Nevada limited liability company (“Tenant”).

     In consideration of the rentals reserved hereunder and the duties, covenants and obligations
of the other hereunder, Landlord and Tenant hereby covenant and agree as follows:

I.

     1.01
Demise of the Premises; Temporary Premises. Landlord hereby leases, demises and lets to Tenant, and Tenant hereby leases and
takes from Landlord, those certain premises (hereinafter sometimes called the “Premises”)
located on Floor 52 (being Suite 5200) of the building known as JPMorgan Chase Tower (the
“Building”) which is situated on Block 67, South Side Buffalo Bayou, in Houston, Harris
County, Texas (hereinafter sometimes called the “Land”), as reflected on the floor plan(s)
attached hereto and made a part hereof for all purposes as EXHIBIT A. The Building, the
Land, all existing underground pedestrian tunnels owned or controlled by Landlord and servicing the
Building and any such tunnels constructed in the future (the “Building Tunnel”) and such
additional facilities to service any of the foregoing in subsequent years as may be necessary or
desirable in Landlord’s reasonable judgment are hereinafter sometimes collectively called the
“Project”.

     During the period commencing on December 1, 2004 and expiring on the date Tenant occupies the
Premises for the purpose of conducting business therefrom, Landlord will make available to Tenant
for Tenant’s occupancy 4,950 square feet of Net Rentable Area located on Floor 62 (being Suite
6275) of the Building currently being subleased by Tenant from SRL, Inc. (the “Temporary
Premises”). Tenant will lease the Temporary Premises on an “AS IS” basis and will pay, with
respect to the Temporary Premises, Additional Rental and all other sums payable by Tenant hereunder
(other than Base Rental and Management Fee Contribution), in the manner set forth herein during the
term of such occupancy.

     1.02
License to Use Public Areas.
Subject to Section 5.03 below, Landlord hereby grants Tenant, its employees, invitees and other
visitors, a nonexclusive license for the term of this Lease and all extensions and renewals thereof
to use, for the purpose of ingress and egress to the Building and the Premises, and in accordance
with the Building Rules (as hereinafter defined) (a) the sidewalks and other exterior common areas
located on the Land; (b) the Building Tunnel; (c) the lobbies, public corridors and elevator foyers
of the Building; and (d) freight elevators, loading dock, mail room and other facilities provided
by Landlord for the common use by tenants of the Building.

     Tenant acknowledges and agrees that the non-exclusive license granted to Tenant pursuant to
this Section 1.02 also includes the right to utilize its proportionate share of designated Building
riser space for the installation of cabling, wiring, conduit, piping, or any
other equipment and/or appurtenance to serve the Premises (“Riser Penetrations”). All
Riser

 

 

Penetration specifications, installations and/or connections shall be first approved by
Landlord in writing before the same are installed (which approval may be withheld in Landlord’s
sole discretion), and the work in connection with all Riser Penetration installations shall be
performed by contractors approved by Landlord and shall be subject to the direction of Landlord.
Any such work must also comply with Landlord’s installation procedures set forth in EXHIBIT
D hereto. Landlord hereby waives any right to charge Tenant an access fee to utilize Tenant’s
proportionate share of designated Building riser space for Tenant’s Riser Penetration requirements.
Landlord reserves the right to designate and control the entity or entities providing Riser
Penetration installation, repair and maintenance in the Building, and to restrict and control
access to the Building risers in connection with such work. In the event Landlord designates a
particular vendor or vendors to provide Riser Penetration installation, repair and maintenance for
the Building, Tenant agrees to abide by and participate in such program. Tenant shall be
responsible for and shall pay all costs incurred in connection with the installation of all Riser
Penetrations in the Building risers and in the Premises, including, without limitation, any
hook-up, access and maintenance fees related to the installation of such Riser Penetrations in the
Building risers and in the Premises and the commencement of service therein, and the maintenance
thereafter of such Riser Penetrations; and there shall be included in Operating Expenses for the
Building all installation, hook-up or maintenance costs incurred by Landlord in connection with
Riser Penetrations in the Building which are not allocable to any individual users of such service
but are allocable to the Building generally. If Tenant fails to maintain all Riser Penetrations
serving the Premises and such failure affects or interferes with the operation or maintenance of
any other Riser Penetrations in the Building, Landlord or any vendor hired by Landlord may enter
into and upon the Premises and/or the Building riser space utilized by Tenant (if any) and perform
such repairs, restorations or alterations as Landlord deems necessary in order to eliminate any
such interference (and Landlord may recover from Tenant all of Landlord’s costs in connection
therewith). Upon termination of the Lease, Tenant, at Landlord’s option, shall remove all Riser
Penetrations installed by Tenant for and during Tenant’s occupancy, which Landlord shall designate
in writing as being subject to removal at the time of installation of same. Tenant agrees that
neither Landlord nor any of its agents or employees shall be liable to Tenant, or any of Tenant’s
employees, agents, customers or invitees or anyone claiming through, by or under Tenant, and hereby
agrees to indemnify Landlord and hold Landlord harmless against any damages, injuries, losses,
expenses, claims or causes of action asserted against Landlord by third parties as a result of
Tenant’s use of the Building risers.

     1.03 Net Rentable Area.

     (a) Landlord and Tenant stipulate and agree for all purposes under this Lease that the Net
Rentable Area of the Premises is 16,285 square feet, notwithstanding any different measurement
thereof that may be made hereafter by or on behalf of either party.

     (b) The Net Rentable Area of the Premises and any space that is added to or deducted from the
Premises during the term of this Lease (without implying any right in Landlord or Tenant to add
space to or deduct space from the Premises, except as expressly set forth in this Lease) shall be
measured as follows:

     (i) as to any full floor leased by Tenant, the Net Rentable Area of the space leased
shall equal the sum of (A) the Net Usable Area of that space, and (B) an allocation

-2-

 

of the
square footage of the Building Common Areas (as hereinafter defined) based upon the ratio
which the Net Usable Area of the space bears to the aggregate Net Usable Area of the office
space in the Building; and

     (ii) as to any partial floor leased by Tenant, the Net Rentable Area of the space
leased shall equal the sum of (A) the Net Usable Area of that space, (B) an allocation of
the square footage of the On-Floor Common Areas (as hereinafter defined) based upon the
ratio which the Net Usable Area of that space bears to the aggregate Net Usable Area of the
floor on which it is located, and (C) an allocation of the area of the square footage of the
Building Common Areas based upon the ratio which the sum of (a) and (B) bears to the
aggregate Net Usable Area of the office space in the Building.

     (c) The Net Usable Area of any space that is added to or deducted from the Premises during the
term of this Lease (without implying any right in Landlord or Tenant to add space to, or deduct
space from, the Premises, except as expressly set forth in this Lease) shall be measured as
follows:

     (i) as to any full floor leased by Tenant, the Net Usable Area of the space leased
shall equal the floor area of that space, measured from the inside surface of the outer
glass line, exterior columns or exterior walls of the Building, including any area within
interior columns or projections necessary to the Building, but excluding all Service Areas
(as hereinafter defined) and Building Common Areas; and

     (ii) as to any partial floor leased by Tenant, the Net Usable Area of the space leased
shall equal the floor area of that space, measured from the inside surface of the outer
glass line, exterior columns or exterior walls enclosing the space to the mid-point of the
walls separating that space from areas leased by or held for lease to other tenants or from
Service Areas, On-Floor Common Areas or Building Common Areas, but including any area within
interior columns or projections necessary to the Building.

     (d) As used herein, the following terms shall mean:

     (i) “Building Common Areas” means the areas within (and measured from the
mid-point of the walls enclosing) the Building’s ground floor and sixtieth (60th)
floor elevator lobbies, concourse, pedestrian tunnels within the Building to the
mid-point(s) of the street(s) adjacent to the Building, elevator machine rooms, mechanical
and electrical rooms serving more than one floor of the Building, telephone and equipment
rooms, janitor closets, central mail room, loading dock and other similar facilities and
areas of the Building that are not leased or held for lease and are necessary or desirable
for the proper utilization of the Building for all tenants, but excluding On-Floor Common
Areas;

     (ii) “On-Floor Common Areas” means, as to each floor above the ground level of
the Building that is not fully leased to a single tenant, the public corridors, elevator
foyers (provided that the sixtieth (60th) floor elevator lobby shall be deemed to
be part of “Building Common Areas”), rest rooms, janitor closets, telephone and
equipment rooms, and other areas on that floor (measured from the mid-point of the
walls enclosing such areas) solely for the use or benefit of all tenants on that floor; and

-3-

 

     (iii) “Service Areas” means the areas within (and measured from the mid-point
of the walls enclosing) the Building’s stairways, fire towers, elevator shafts, flues,
vents, stacks, pipe shafts and vertical ducts, other than those, if any, that are for the
specific use of Tenant (such as special stairs or elevators).

     1.04 Term.

     (a) The term of this Lease (the “Term”) shall commence on the date Landlord tenders
possession of the Premises to Tenant, which shall occur promptly following the mutual execution of
this Lease (the “Commencement Date”). Tenant’s obligation to pay Stated Rentals shall not
commence until the earlier to occur of (i) thirty (30) days following the date Tenant occupies the
Premises for the purpose of conducting business therefrom or (ii) May 1, 2005 (the “Rent
Commencement Date”). Unless sooner terminated in accordance with the terms and conditions set
forth herein, the Term shall expire on the last day of the eighty-fourth (84th) full
calendar month from and after the Rent Commencement Date (the “Expiration Date”).

     (b) Upon the request of Landlord at any time after the Commencement Date, Tenant shall execute
and deliver to Landlord a declaration (in a form provided by Landlord) specifying the Commencement
Date, the Rent Commencement Date and the Expiration Date, among other matters.

     1.05 Use.

     (a) The Premises are to be used and occupied by Tenant (and its assignees and subtenants
permitted hereunder) solely for general office use and for no other purpose. Without limiting the
foregoing, the Premises shall not be used for any purpose which would tend to lower the first-class
character of the Building, or create unreasonable elevator loads or otherwise interfere with
standard Building operations, and Tenant shall not engage in any activity which is not in keeping
with the standards of the Building.

     (b) Tenant shall not occupy or use the Premises, or permit any portion of the Premises to be
occupied or used, for any business or purpose which is unlawful, disreputable or deemed to be
hazardous on account of fire or other hazards, or permit anything to be done which would in any way
increase the rate of fire or liability or any other insurance coverage on the Building and/or its
contents. Tenant agrees that no food, soft drink or other vending machine will be installed within
the Premises without the written consent of Landlord.

     1.06 Downtown Tunnel System.
Landlord makes no warranty or representation respecting the use or availability of or access to any
of the downtown tunnel system that is not within the property lines of the Land. If
(a) any license pertaining to any portion of the downtown tunnel system that is outside of the
property lines of the Land is revoked, curtailed or in any way modified by any federal, state or
municipal authority, public utility or any other party, or (b) the person or entity owning or
controlling any portion of the downtown tunnel system that is outside of the property lines of the
Land closes or restricts access thereto, Landlord shall not be subject to any liability nor shall
Tenant be entitled to any compensation, diminution or abatement of Rent hereunder by virtue of such
action.

II.

     2.01 Base Rental. Tenant hereby
covenants and agrees to pay to Landlord base annual rental (the “Base Rental”), which shall
be payable in monthly installments in advance on the first day of each month beginning on the Rent
Commencement Date according to the following schedule:

	 	 	 	 	 	 	 	 	 	 	 	 	 
	 	 	Base Rental Rate	 	 	Annual	 	 	Monthly	 
	Time Period	 	PSF/NRA	 	 	Base Rent	 	 	Base Rent

	Months 49 – 84
	 	$	12.19	 	 	$	198,514.15	 	 	$	16,542.85	 

     2.02 Additional Rental.

     (a) In addition to the Base Rental, for each calendar year (or portion thereof) during the
Term of this Lease, commencing on the Rent Commencement Date, Tenant shall pay as additional rent
(the “Additional Rental”) Tenant’s Proportionate Share (as hereinafter defined) of
Operating Expenses (as hereinafter defined) for that year. On or about the beginning of each
calendar year during the term of this Lease, Landlord shall deliver to Tenant Landlord’s good faith
estimate (the “Estimated Additional Rental”) of the Additional Rental for that year. The
Estimated Additional Rental shall be paid in equal installments in advance on the first day of each
month. If Landlord does not deliver an estimate to Tenant for any year by January 1 of that year,
Tenant shall continue to pay Estimated Additional Rental based on the prior year’s estimate. From
time to time during any calendar year, Landlord may revise its estimate of the Additional Rental
for that year based on either actual or reasonably anticipated increases in Operating Expenses, and
the monthly installments of Estimated Additional Rental shall be appropriately adjusted for the
remainder of that year in accordance with the revised estimate so that by the end of the year, the
total payments of Estimated Additional Rental paid by Tenant shall equal the amount of the revised
estimate.

     (b) “Tenant’s Proportionate Share” means the percentage determined by dividing the Net
Rentable Area contained within the Premises by the total Net Rentable Area leased or held for lease
for general office purposes within the Building for such year. Landlord and Tenant hereby
stipulate and agree for all purposes under this Lease that the total Net Rentable
Area of the office space within the Building is 1,594,605 square feet, notwithstanding any
different measurement thereof that may be made hereafter by or on behalf of either party.

     (c) “Operating Expenses”, as that term is used herein, means all expenses, costs and
disbursements of every kind and nature, computed on an accrual basis, incurred or paid in
connection with the ownership, operation, maintenance and repair of the Project, excluding only the
costs and expenses described in Section 2.02(e) below. Without limiting the generality of the
foregoing, Operating Expenses include the following:

     (i) wages and salaries of all persons (up to the level of building manager) directly

maintenance of the Project;

     (iii) rental and other normal office expenses for Landlord’s on-site management office;

     (iv) the cost of all utilities for the Project, including but not limited to, water and

     (v) the cost of all maintenance and service agreements for the Project and the
equipment therein, including, but not limited to, access control, window cleaning, elevator

     (vi) the cost of repairs and general maintenance for the Project (excluding repairs and
general maintenance costs that are paid by proceeds of insurance or by Tenant or other third

     (vii) the cost of installation of capital investment items that have been or are
hereafter installed for the purpose of reducing Operating Expenses, to improve Building
life-safety systems or which may be required or recommended by any laws, ordinances, orders,
rules, regulations and requirements which impose any duty with respect to or otherwise
relate to the use, condition, occupancy, maintenance or alteration of the Project, whether
now in force or hereafter enacted, in each case amortized over the reasonable life of the
capital investment item, with the reasonable life and amortization schedule being determined
in accordance with generally accepted accounting principles, together with interest thereon
at the rate of ten percent (10%) per annum;

     (viii) the Office Portion (as defined below) of the cost of all insurance relating to
the Project, including, but not limited to, the cost of property, rental loss and liability
insurance applicable to the Project and Landlord’s personal property used in connection
therewith and any deductibles on insurance proceeds paid to Landlord;

     (ix) the Office Portion of all taxes, assessments and governmental charges, whether
directly paid by Landlord, whether federal, state, county or municipal, and whether imposed
by taxing districts or authorities (including, without limitation, the
Houston downtown management district) presently taxing the Project or by others
subsequently created or otherwise, and any other taxes and assessments attributable to the
Project or its operation (including any taxes or assessments allocated to leasehold
improvements unless a separate allocation is made therefor by the applicable taxing
authority), excluding, however, federal and state taxes on income, death taxes, franchise
taxes, and any taxes imposed or measured on or by the income of Landlord from the operation
of the Project (excluding ad valorem taxes on the Project determined by reference to
Landlord’s income from the Project) or imposed in connection with any change of ownership of
the Project; provided, however, that if at any time during the Term, the present method of
taxation or assessment shall be so changed that the whole or any part of the taxes,
assessments, levies, impositions or charges now levied, assessed or imposed on real estate
and the improvements thereof shall be changed and as a substitute

-6-

 

therefor, or in lieu of or
in addition thereto, taxes, assessments, levies, impositions or charges shall be levied,
assessed or imposed wholly or partially as a capital levy or otherwise on the rents received
from the Project or the Rent (as defined in this Lease) reserved in this Lease or any part
thereof, then such substitute or additional taxes, assessments, levies, impositions or
charges, to the extent so levied, assessed or imposed, shall be deemed to be included within
Operating Expenses;

     (x) any lease payments made by Landlord for any equipment used in the operation or
maintenance of the Project, excluding, however, any part of such lease payments that
constitutes capital expenditures under generally accepted accounting principles, except as
provided in clause (vii) above; and

     (xi) Landlord’s (or Landlord’s managing agent’s) accounting and external and internal
audit costs and attorneys’ fees applicable to the Project (provided that costs charged under
this Section 2.02(c)(xi) shall not duplicate costs charged under Section 2.02(c)(i) above).

     (d) “Office Portion” means the percentage of the gross leasable area of the Building
that is leased or held for lease as office space, which Landlord and Tenant stipulate and agree for
purposes of Sections 2.02(c)(viii) and (ix) above shall be deemed to be ninety-five percent (95%).

     (e) Landlord hereby agrees that the term “Operating Expenses” shall not include (i) debt
service or rentals under any ground lease; (ii) costs for which Landlord is entitled to specific
reimbursement as a separate charge by Tenant, by any other tenant of the Building or by any other
third party; (iii) costs incurred by Landlord in connection with the negotiation of any tenant
lease in the Project, including leasing commissions, legal fees, promotional expenses, and
leasehold improvements expenses (and/or allowances therefor); (iv) any other costs and expenses for
services or amenities that are specifically for the benefit of a particular tenant and that are of
a nature not generally provided to all tenants in the Building; (v) costs (including, but not
limited to, penalties, fines and associated legal expenses) incurred by Landlord due to the
violation by Landlord, Tenant or any tenant in the Building of the terms and conditions of this
Lease or of the leases of other tenants in the Building or applicable federal, state, and local
government laws, codes and similar regulations that would not have been incurred but for any such
violations by Landlord, Tenant, or other tenants in the Building, it being intended that each party
shall be
responsible for the costs resulting from its own violation of such leases and laws, codes and
regulations as same shall pertain to the Building (it being acknowledged and agreed that costs of
initial compliance of laws enacted or changed after the date of this Lease otherwise permitted
under this Lease to be passed-through to tenants as Operating Expenses shall not be excluded as a
result hereof, i.e., only additional costs incurred as a result of Landlord’s failure to comply
with such laws, within applicable cure periods after the enaction or change thereof shall be
excluded); (vi) except as set forth in Section 2.02(c)(vii) above, expenditures classified as
capital expenditures for federal income tax purposes or any non-cash charges such as depreciation
or amortization; or (vii) property management fees.

     (f) Within one hundred fifty (150) days after the end of each calendar year during the Term of
this Lease, or as soon as reasonably practicable thereafter, Landlord shall provide

-7-

 

Tenant a
reasonably detailed statement showing the Operating Expenses (including Taxes) for said calendar
year, prepared in accordance with generally accepted accounting principles, and a statement
prepared by Landlord comparing Estimated Additional Rental paid by Tenant with Additional Rental.
If Landlord fails to deliver a statement with respect to any calendar year within two (2) years
following the end of the calendar year in question, Landlord shall not be able to collect from
Tenant any shortfalls of Additional Rental for such year. Tenant shall have the right to request
and review, at
Tenant’s expense, Landlord’s books and records regarding the
determination of Additional Rental for the previous calendar year only upon written notice to
Landlord and scheduling an appointment in advance. Such notice must be delivered and audit
performed within one hundred twenty (120) days following Landlord’s delivery of
Landlord’s annual statement to Tenant. Any such auditor must be an employee of Tenant, a
certified public accountant from a reputable accounting firm reasonably acceptable to Landlord or
qualified real estate accounting professionals from a reputable real estate services firm
reasonably acceptable to Landlord. No audits by contingency fee-based consultants shall be
permitted. Prior to any audit being conducted, Tenant and such auditor(s) shall execute a
confidentiality agreement (in a form submitted by Landlord and reasonably acceptable to Tenant).
Tenant shall submit its audit results and any objections to Landlord’s statement within thirty (30)
days after the completion of Tenant’s audit. Thereafter, the parties shall proceed in good faith
to attempt to resolve any dispute regarding Landlord’s statement within thirty (30) days following
receipt of Tenants’ audit results. In the event that Landlord and Tenant confirm pursuant to
Landlord’s statement or Landlord’s acceptance or verification of the results of
Tenant’s audit, that Estimated Additional Rental paid by Tenant exceeds Additional Rental for
said calendar year, Landlord shall pay Tenant an amount equal to such excess at Landlord’s
option, by either giving a credit against rentals next due, if any, or by direct payment to Tenant
within thirty (30) days of the date of such statement. In addition, if Tenant’s third-party
audit reflects that Estimated Additional Rental exceeds Additional Rental by more than five percent
(5%) for such period, and Landlord accepts Tenant’s audit conclusions or confirms same as a
result of an independent audit or review of the disputed items by a certified public accountant
conducted at Landlord’s expense, Landlord shall also reimburse Tenant for the reasonable cost
of Tenant’s audit and for interest on the amount of Tenant’s overpayment at the Default
Rate for the period commencing on the date of Landlord’s delivery of the statement through
the date Tenant receives the refund of its overpayment from Landlord. In the event that the
Additional Rental exceeds Estimated Additional Rental for said calendar year, Tenant shall pay the
difference to Landlord within thirty (30) days of receipt of th
e statement. The provisions of this
Section 2.02(f) shall survive the expiration or termination of this Lease.

     (g) Notwithstanding any other provision herein to the contrary, if the Building is not fully
occupied during any calendar year or if the entire Building is not provided with Building standard
services during any calendar year, an adjustment shall be made in computing each component of the
Operating Expenses for such year so that Operating Expenses shall be computed for such year as
though the Building had been fully occupied during such year and as though the entire Building had
been provided with Building standard services during such year.

     2.03 Management Fee Contribution.
In addition to the Base Rental and Additional Rental, for each year during the term of this Lease,
commencing on the Rent Commencement Date, Tenant shall pay a management fee contribution (the
“Management Fee Contribution”) in an amount equal to three percent (3%) of the sum of the
Base Rental and Additional Rental

-8-

 

payable for that year. The Management Fee Contribution shall be
paid in equal installments in advance on the first day of each month (with the calculation thereof
being based on the Estimated Additional Rental then payable by Tenant hereunder). Landlord shall
determine (and adjust, if necessary) Tenant’s actual Management Fee Contribution annually in
conjunction with Landlord’s determination of actual Additional Rental in accordance with Section
2.02(f). Additional payments required by, or refunds by Landlord to, Tenant that are attributable
to such determination of Tenant’s actual Management Fee Contribution will be made by Tenant, or
Landlord, as applicable in the same manner as provided in Section 2.02(f) with respect to
additional payments or refunds of Additional Rental.

     2.04 Rental Payments.

     (a) Tenant hereby covenants and agrees to pay the Base Rental, Additional Rental and
Management Fee Contribution (collectively, the “Stated Rentals”) and all other sums of
money as shall become due from and payable by Tenant to Landlord under this Lease (collectively,
“Rent”) to Landlord at Landlord’s address as provided herein (or such other address as may
be designated by Landlord in writing from time to time) monthly in advance.

     (b) If the term of this Lease as described above commences on other than the first day of a
calendar month or terminates on other than the last day of a calendar month, then the installments
of Stated Rentals for such month or months shall be prorated and the installment or installments so
prorated shall be paid in advance. The payment for such prorated month shall be calculated by
multiplying the monthly installment by a fraction, the numerator of which shall be the number of
days of the Lease term occurring during said commencement or termination month, as the case may be,
and the denominator of which shall be the total number of days occurring in said commencement or
termination month.

     (c) Tenant shall pay all Rent at the times and in the manner provided in this Lease, without
abatement, demand, set-off or counterclaim. Tenant hereby acknowledges and agrees that (i)
Landlord and Tenant have expressly negotiated that except as otherwise provided in this Lease,
Tenant’s covenants to pay Rent under this Lease are separate and independent from Landlord’s
covenant to provide services and other amenities hereunder and (ii) had the parties not mutually
agreed upon the independent nature of Tenant’s covenants to pay all Rent
hereunder, Landlord would have required a greater amount of Rent in order to enter into this
Lease.

     (d) All Rent shall bear interest from the date due until paid at a rate (the “Default
Rate”) equal to the lesser of (i) a floating rate equal to five percent (5%) above the Prime
Rate reported in the Money Rates column or section of the most recent issue of The Wall
Street Journal, automatically adjusting with each change in the Prime Rate, and (ii) the maximum
non-usurious rate of interest permitted by the applicable laws of the State of Texas, as determined
by reference to the indicated (weekly) rate ceiling (as defined and described in Chapter 303 of the
Texas Finance Code (or any successor statute), as amended) at the applicable time in effect.

     2.05
Security Deposit. On the
date of execution of this Lease by Tenant, there shall be due and payable by Tenant a security
deposit in the amount of $7,803.23, such deposit to be held for the performance by Tenant of
Tenant’s covenants and obligations under this Lease, it

-9-

 

being expressly understood that the deposit
shall not be considered an advance payment of rental or a measure of Landlord’s damages in case of
default by Tenant. Upon the occurrence of any event of default by Tenant or breach by Tenant of
Tenant’s covenants or obligations under this Lease, Landlord may, from time to time, without
prejudice to any other remedy, use the security deposit to the extent necessary to make good any
arrears of rental or other payments hereunder and/or any damage, injury, expense or liability
caused to Landlord by such event of default or breach of covenant. Following any such application
of the security deposit, Tenant shall pay to Landlord on demand the amount so applied in order to
restore the security deposit to the amount thereof existing prior to such application. Any
remaining balance of the security deposit shall be returned by Landlord to Tenant within thirty
(30) days after the termination of this Lease; provided, however, Landlord shall have the right to
retain and expend such remaining balance (a) to reimburse Landlord for any and all rentals or other
sums due hereunder that have not been paid in full by Tenant and/or (b) for cleaning and repairing
the Premises if Tenant shall fail to deliver same at the termination of this Lease in a neat and
clean condition and in as good a condition as existed at the date of possession of same by Tenant,
ordinary wear and tear only excepted. Tenant shall not be entitled to any interest on the security
deposit.

     2.06 Waiver of Section 93.012, Texas Property Code. Please do not type any text in
this area. . Landlord and Tenant are knowledgeable and experienced in commercial leasing
transactions and agree that the provisions of this Lease for determining all charges, amounts, and
Additional Rental payable by Tenant (including, without limitation, payments under this Article 2),
are commercially reasonable and valid even though such methods may not state a precise mathematical
formula for determining such charges. Accordingly, Tenant voluntarily and knowingly waives all
rights and benefits of a tenant under Section 93.012, Texas Property Code, or its successor statute
or code provision. Nothing contained in this waiver however is intended to limit or impair any
other remedy available to Tenant under the Lease or at law or in equity (other than Section 93.012,
Texas Property Code, or its successor statute or code provision). In addition, nothing in this
Section 2.06 shall constitute a waiver of Tenant’s right to dispute and/or initiate a claim
disputing Landlord’s methods of calculating or determining Operating Expenses and/or Landlord’s
calculation or determination of Additional Rent.

     2.07 Rental Abatement. Please do not type any text in this area. .
Notwithstanding any provisions of this Lease to the contrary, Landlord hereby agrees that in
consideration for the execution of this Lease by Tenant, and as an inducement to Tenant to so
execute this Lease, the payment of Stated Rentals accruing from the Commencement Date until the
Rent Commencement Date is waived by Landlord and Tenant shall have no obligation to pay same,
except as provided in Section 8.03(d) below.

III.

     3.01 Services. Provided no Event
of Default (as hereinafter defined) has occurred and is continuing hereunder, and subject to the
provisions of Sections 3.02 and 3.03 below, Landlord shall furnish the following services and
amenities (collectively, the “Required Services”) to Tenant (and its assignees and
subtenants permitted hereunder) while occupying the Premises:

     (a) Hot and cold domestic water at those points of supply provided for general use of the
tenants of the Building;

-10-

 

     (b) Central heat, ventilation and air conditioning in season, at such times, at such
temperatures and in such amounts as are considered by Landlord to be standard, but in keeping with
the standards of other first-class office buildings in the Central Business District of Houston,
Texas, all as more particularly described on EXHIBIT C attached hereto and made a part
hereof for all purposes;

     (c) Electric lighting service for all public areas and special service areas of the Building
in the manner and to the extent deemed by Landlord to be in keeping with the standards of other
first class office buildings in the Central Business District of Houston, Texas;

     (d) Janitorial service comparable to that provided by landlords of other first-class office
buildings in the Central Business District of Houston, Texas and consistent with other similar
tenants in the Building on a five (5) day week basis in accordance with the specifications set
forth on EXHIBIT E attached hereto; provided, however, if Tenant’s floor coverings or other
improvements require special cleaning or care in excess of that provided for by Landlord in
EXHIBIT E, Landlord will provide such additional cleaning or care only upon special
agreement with Tenant;

     (e) On-site access control personnel and equipment for the Project; provided, however, that
Tenant agrees that Landlord shall not be responsible for the adequacy or effectiveness of such
access control service provided that (i) Landlord has exercised reasonable care in the selection of
the access control contractor and equipment, and (ii) the scope and extent of the access control
services contracted for by Landlord are in keeping with the standards of other first-class office
buildings in the Central Business District of Houston, Texas;

     (f) Sufficient electrical capacity distributed to a panel box located at the core of each
floor of the Premises to operate (i) typewriters, voice writers, calculating machines and other
machines of similar low voltage electrical consumption (120 volts, single phase) and (ii) lighting
and equipment of standard high voltage electrical consumption (277 volts, single phase), to
the extent that the total design load of low electrical voltage and high electrical voltage within
the Premises in the aggregate does not exceed six (6) watts per square foot of Net Usable Area.

     Should Tenant’s non-linear electrical load (created by equipment such as personal computers,
television sets, laser printers, copiers or other electronic devices connected to the power system)
result in harmonic distortion conditions which cause any adverse effects in the Project, including
but not limited to, deration of any transformer, distribution stepdown transformer failures,
overheating or melting of neutral conductors, or malfunctioning of various electronic components,
Tenant acknowledges that Tenant, at Tenant’s sole cost, shall be obligated to eliminate such
harmonic distortion conditions and to repair any damage which results from such harmonic distortion
within thirty (30) days of Landlord’s request. If Tenant fails to eliminate such harmonic
distortion and repair such damage caused thereby within such thirty (30) day period, Landlord, at
its option, may make such corrections deemed necessary by Landlord to eliminate such harmonic
distortion and make such repairs, and Tenant shall pay to Landlord on demand Landlord’s cost
thereof plus a charge equal to fifteen percent (15%) of such costs for administrative cost
recovery.

-11-

 

     Tenant shall cause Tenant’s electrical system serving any equipment producing non-linear
electrical loads to be designed to accommodate such non-linear electrical loads, including but not
limited to, over-sizing neutral conductors, derating transformers and/or providing power line
filters. Tenant’s plans for any Leasehold Improvements shall include a calculation of Tenant’s
fully connected design load with and without demand factors and shall indicate the number of watts
of un-metered and sub-metered loads.

     If Tenant’s electrical equipment and lighting require electrical circuits, transformers or
other additional equipment in excess of Tenant’s pro rata share of the Building’s electrical or
HVAC systems (which additional equipment shall be hereinafter referred to as the “Additional
Electrical Equipment”), Tenant may (at Tenant’s cost, including the cost to design, install,
maintain and replace the Additional Electrical Equipment [including the meters]) install same,
provided such installation is compatible with existing Building systems, will not compromise
Landlord’s ability to provide services to Tenant or other tenants of the Building and will not be
burdensome to the Project or to Landlord, in Landlord’s opinion, and Tenant shall pay all operating
costs related to that requirement (including, without limitation, the cost of electricity, water or
other services consumed through, or in connection with, the Additional Electrical Equipment).

     The method of design and installation of any Additional Electrical Equipment (including any
related meter) required by Tenant shall be subject to the prior written approval of Landlord and
shall be performed by Landlord at Tenant’s sole cost (including a charge equal to fifteen percent
(15%) of such cost for the review and installation of such Additional Electrical Equipment for
administrative cost recovery).

     Tenant shall pay to Landlord the cost of electricity consumed in excess of the Building
standard rated electrical design load as determined by meter, or if not metered, as otherwise
reasonably estimated by Landlord, plus any actual accounting expenses incurred by Landlord in
connection with the metering thereof. Landlord may cause the entire Premises to be separately
metered (at Tenant’s expense, including, without limitation, the cost of installing,
maintaining, repairing and replacing such meters to the extent necessary), in which event Tenant
shall pay the actual cost of electricity consumed by Tenant.

     (g) All Building standard fluorescent bulb replacement in all areas and all incandescent bulb
replacement in public areas outside of the Premises, rest rooms and stairwells;

     (h) Non-exclusive passenger elevator service to the Premises twenty-four (24) hours per day
and non-exclusive freight elevator service during normal business hours; and

     (i) Maintenance of the roof, exterior walls, load-bearing columns, foundation, floor slabs,
and other structural components, the mechanical, electrical and plumbing systems, the Building
Common Areas and On-Floor Common Areas (including restrooms), and exterior lighting and landscaping
of the Project.

     3.02 Governmental Regulations. The
obligations of Landlord to provide the Required Services shall be subject to governmental
regulation thereof (i.e., rationing, temperature control, etc.) and any such regulation that
impairs Landlord’s ability to provide the

-12-

 

Required Services as herein stipulated shall not
constitute a default hereunder but rather providing the applicable Required Services to the extent
allowed pursuant to such regulations shall be deemed to be full compliance with the obligations and
agreements of Landlord hereunder.

     3.03 Failure to Provide Required Services. To the extent any of the Required Services require electricity, gas and water supplied
by public utilities or others, Landlord’s covenants hereunder shall only impose on Landlord the
obligation to use its commercially reasonable, good faith efforts to cause the applicable public
utilities or other providers to furnish the same. Failure by Landlord to furnish any of the
Required Services to any extent, or any cessation thereof, due to failure of any public utility or
other provider to furnish service to the Building, or any other cause beyond the reasonable control
of Landlord, shall not render Landlord liable in any respect for damages to either person or
property, nor be construed as an eviction of Tenant, nor except as provided below result in an
abatement of Rent, nor relieve Tenant from fulfillment of any covenant or agreement hereof. In the
event of any failure by Landlord to furnish any of the Required Services to any extent, or any
cessation thereof (a AService Interruption@), Landlord shall utilize its
diligent, good faith efforts to promptly restore said Required Services as soon thereafter as is
reasonably possible under the circumstances. If (i) any Service Interruption of an Essential
Required Service (as defined below) renders all or any portion of the Premises untenantable, (ii)
such cessation does not arise as a result of the gross negligence or willful misconduct of Tenant,
its agents, employees or contractors, (iii) such cessation is not caused by a fire or casualty (in
which case Section 6.03 shall control), (iv) Tenant notifies Landlord of such cessation and (v)
such failure or cessation continues for five (5) consecutive business days, Rent with respect to
the untenantable portion of the Premises shall be abated thereafter (or retroactively from the date
the Service Interruption commenced if the Service Interruption is an insured event) until the
Essential Required Service(s) are restored or the affected portion(s) of the Premises are otherwise
returned to a tenantable condition. The Premises shall be considered “untenantable” if they are not
reasonably usable by Tenant for the normal operation of its business. As used herein, the term
“Essential Required Service” means any one or more of the following services: HVAC, electricity,
water and/or elevator service to the Premises. The foregoing abatement of Rent remedy shall be
Tenant’s sole remedy in the event of a Service Interruption of an Essential Required Service.

     3.04 Additional Services. Tenant
hereby acknowledges and agrees that Landlord is obligated to provide only the Required Services
under this Lease, and that Landlord, its agents and representatives, have made no representations
whatsoever of any additional services or amenities to be provided by Landlord now or in the future
under this Lease. Notwithstanding the foregoing, Tenant recognizes that Landlord may, at
Landlord’s sole option, elect to provide additional services or amenities for the tenants of the
Building from time to time, and hereby agrees that Landlord’s discontinuance of any provision of
any such additional services or amenities shall not constitute a default of Landlord under this
Lease nor entitle Tenant to any abatement of or reduction in Rent. Any such additional services or
amenities that Landlord elects to provide to tenants of the Building shall be provided to those
tenants requesting such services or amenities at Landlord’s cost therefor which cost may include an
administrative cost recovery charge not to exceed ten percent (10%).

-13-

 

IV.

     4.01 Care of the Premises.

     (a) Tenant shall not commit or allow to be committed any waste or damage to any portion of the
Premises or the Building, and shall at its own cost and expense, maintain the Premises in good
condition and repair. If Tenant fails to make required repairs or replacements to the Premises
promptly, Landlord may, at its option, make such repairs or replacements, and Tenant shall repay
the cost thereof plus a charge of fifteen percent (15%) to the Landlord on demand. Tenant shall
not undertake the repair or replacement of any damage or injury to the structural components of the
Building or its mechanical, electrical or plumbing systems caused by Tenant, its agents,
contractors, employees, invitees or visitors, but shall reimburse Landlord for all costs and
expenses incurred in effecting any such repair or replacement, plus a charge of ten percent (10%).

     (b) Unless otherwise expressly stipulated herein, Landlord shall not be required to make any
improvements to or repairs of any kind or character to the Premises during the term of this Lease.

     (c) Upon termination of this Lease, by lapse of time or otherwise, Tenant shall deliver up the
Premises to Landlord in as good condition as existed on the Commencement Date, ordinary wear and
tear only excepted. Upon such termination of this Lease, Landlord shall have the right to re-enter
and resume possession of the Premises.

     4.02 Entry for Repairs and Inspection. Tenant shall permit Landlord and its contractors, agents or representatives to enter
into and upon any part of the Premises at all reasonable hours and upon reasonable notice (except
for entry after-hours for cleaning and in the case of emergency, in which events no notice shall be
required) to inspect or clean the same, to make repairs, alterations or additions thereto, to show
the same to prospective tenants or purchasers, to determine whether Tenant is performing its
obligations hereunder or for any other purpose as Landlord may deem necessary or desirable.
Landlord agrees to exercise reasonable good faith efforts (a) to prosecute completion of any work
within the Premises diligently, (b) to minimize interference with Tenant’s use, access, occupancy
and quiet enjoyment of the Premises, and (c) to protect Tenant’s property located in the Premises
from damage. Entry to the Premises and the conduct of work therein by Landlord and its employees,
contractors, agents or representatives pursuant to this Section 4.02 shall not constitute a
trespass or an eviction (constructive or otherwise) nor shall Tenant be entitled to any abatement
or reduction of Rent or claim for damages for any injury to or interference with Tenant’s business,
loss of occupancy or quiet enjoyment or for any other consequential damages by reason thereof.

     4.03 Nuisance. Tenant shall
conduct its business and control its agents, employees, invitees, contractors and visitors in such
manner as not to create any nuisance, or interfere with, annoy or disturb any other tenant, or
Landlord in its operation of the Building.

     4.04 Laws and Regulations; Rules of the Building. Tenant, at Tenant’s expense, shall comply with, and Tenant shall cause its
visitors, employees, contractors, agents and invitees to comply with (a) all laws, ordinances,
orders, rules, regulations and other requirements of

-14-

 

governmental authority which impose any duty with respect to or otherwise relate to the use, condition, occupancy, maintenance or alteration of
the Premises, whether now in force or hereafter enacted, and (b) all rules and regulations
reasonably adopted and altered by Landlord from time to time for the use, safety, care and
cleanliness of the Building and for preservation of good order therein (the “Building
Rules”), which Building Rules will be sent by Landlord to Tenant in writing and shall be
thereafter carried out and observed by Tenant, its employees, contractors, agents, invitees and
visitors. The current Building Rules are attached hereto as EXHIBIT D and made a part
hereof for all purposes.

     4.05
Hazardous Substances.

     (a) Tenant shall use its diligent good faith efforts to comply with all applicable federal,
state or local laws, regulations, orders, judgments and decrees regarding health, safety or the
environment (“Environmental Laws”) pertaining to or governing Tenant’s particular use and
occupancy of the Premises or the conduct of Tenant’s business therein, including without limitation
the application for and maintenance of all required permits, the submittal of all notices and
reports, proper labeling, training and record keeping, and timely and appropriate response to any
release or other discharge by Tenant of a substance under Environmental Laws.

     (b)Landlord shall use its diligent good faith efforts to comply with all Environmental Laws
pertaining to or governing Landlord’s ownership, operation, maintenance and repair of the Project,
including without limitation the application for and maintenance of all required permits, the
submittal of all notices and reports, proper labeling, training and record keeping, and timely and
appropriate response to any release or other discharge by Landlord of a substance under
Environmental Laws.

     (c)Landlord represents to Tenant as of the date hereof that (x) Landlord has not received any
written notice from any applicable governmental authority alleging any pending violation by
Landlord or the Project with any Environmental Law, and (y) to Landlord’s actual knowledge as of
the date of this Lease, no violation of any Environmental Law now exists with respect to the
Premises or the On-Floor Common Areas on Floor 52 of the Building.

V.

     5.01
Condition of the Premises and the Project.

     (a) The Premises shall be delivered to Tenant, and Tenant shall accept same, in its then
current condition, broom clean with only the additional leasehold improvements and tenant finish,
if any, set forth and described on EXHIBIT B, and with all Building systems serving the
Premises in good working order, but otherwise “AS IS” and “WITH ALL FAULTS” and “WITHOUT WARRANTY,
EXPRESS OR IMPLIED” (except for latent defects in base-building improvements and Landlord’s
obligation to complete the Landlord’s Work as provided in EXHIBIT B). As used in this
Lease, the term “Leasehold Improvements” means any and all improvements and tenant finish
existing in the Premises as of the Commencement Date, including the Initial Leasehold Improvements,
if any, to be installed pursuant to EXHIBIT B, as well as any and all Premises Alterations
(as defined below) and subsequent improvements made to the Premises during the term of this Lease.

-15-

 

     (b)Tenant acknowledges that no representations as to the repair of the Premises or the
Project, nor promises to alter, remodel or improve the Premises or the Project, have been made by
Landlord, except as are expressly set forth in this Lease.

     5.02
Alterations to the Premises.

     (a) Tenant shall not make or allow to be made any alterations, physical additions or other
improvements (including fixtures) in or to the Premises (any such alterations, additions and other
improvements made to the Premises following the Commencement Date being herein called “Premises
Alterations”), or place safes, vaults or other heavy furniture or equipment within the
Premises, without first obtaining Landlord’s written approval of Tenant’s contractors and the plans
and specifications therefor. If such approval is given, prior to commencement of construction
Tenant shall deliver to Landlord all building permits required for such construction and a copy of
the executed construction contract covering such Premises Alterations. Landlord’s approval, if
given, shall create no responsibility or liability on the part of Landlord for, or
warranty by Landlord with respect to, the completeness or design sufficiency or compliance
with any laws, ordinances, orders, rules, regulations or other requirements of governmental
authority applicable thereto. Tenant shall pay to Landlord, upon demand, a fee to reasonably
compensate Landlord for the cost of review and monitoring the construction of such Premises
Alterations. Tenant shall also deliver to Landlord a copy of the “as-built” plans and
specifications for all Premises Alterations on a diskette in AutoCAD or compatible format promptly
following completion thereof.

     (b) All Leasehold Improvements (other than Tenant’s trade fixtures) shall become the property
of Landlord at the end of the term of this Lease and shall be surrendered to Landlord upon
termination of this Lease, whether by lapse of time or otherwise; provided, however, that upon
Landlord’s written request Tenant shall remove any Leasehold Improvements designated by Landlord
and repair and restore any damage to the Premises caused thereby.

     (c) Tenant shall indemnify and hold harmless Landlord from and against all costs (including
reasonable attorneys’ fees and costs of suit), losses, liabilities, or causes of action arising out
of or relating to any Premises Alterations, including but not limited to any mechanics’ or
materialmen’s liens asserted in connection therewith. Should any mechanics’ or other liens be
filed against any portion of the Building and/or the Land or any interest therein by reason of
Tenant’s acts or omissions or because of a claim against Tenant or its contractors, Tenant shall
cause the same to be cancelled or discharged of record by bond or otherwise within ten (10) days
after notice by Landlord. If Tenant shall fail to cancel or discharge said lien or liens, within
said ten (10) day period, which failure shall be deemed to be a default hereunder, Landlord may, at
its sole option and in addition to any other remedy of Landlord hereunder, cancel or discharge the
same and upon Landlord’s demand, Tenant shall promptly reimburse Landlord for all costs incurred in
cancelling or discharging such lien or liens.

     5.03
Alterations to the Building. Notwithstanding anything herein to the contrary, Landlord hereby expressly reserves the right in
its sole discretion to (a) temporarily or permanently change the location of, close, block or
otherwise alter any entrances, corridors, skywalks, tunnels, doorways or walkways leading to or
providing access to the Building or any part thereof or otherwise restrict the use of same provided
such activities do not unreasonably

-16-

 

impair Tenant’s access to the Premises, and (b) improve,
remodel, expand or otherwise alter any of the Building, and it is agreed that Landlord shall not
incur any liability whatsoever to Tenant as a consequence thereof and such activities shall not be
deemed to be a breach of any of Landlord’s obligations hereunder. Landlord agrees to exercise good
faith in notifying Tenant within a reasonable time in advance of any alterations, modifications or
other actions of Landlord under this Section 5.03. Any diminution or obstruction of light, air or
view by any structure which is not or may hereafter be constructed on lands adjacent to the Project
shall in no way affect this Lease or impose any liability on Landlord. Noise, dust or vibration or
other incidents to any construction work in or around the Building shall in no way affect this
Lease or impose any liability on Landlord.

     5.04 Keys and Locks. Landlord shall furnish Tenant with twenty (20) keys for the Building corridor doors
entering the Premises. Additional corridor door entry keys will be furnished by Landlord upon an
order signed by Tenant and payment by Tenant of Landlord’s charge therefor. All such keys shall
remain the property of Landlord. No additional locks shall be allowed on any door entering or
within the Premises without Landlord’s permission, and Tenant shall not make or permit to be made
any duplicate keys, except those furnished by Landlord. Upon termination of this Lease, Tenant
shall surrender to Landlord all keys to any locks on doors entering or within the Premises, and
give to Landlord the explanation of the combination of all locks for safes, safe cabinets and vault
doors, if any, in the Premises.

     5.05 Graphics, Building Directory and Name. No signs, numerals, letters or other graphics shall be used or permitted on the
exterior of the Premises, or which may be visible from outside the Premises, unless approved in
advance and in writing by Landlord. Landlord shall initially provide and install, at Landlord’s
expense, Building standard tenant name signage at the entrance to the Premises. All such graphics
shall be of Building standard design and quality unless otherwise approved in advance by Landlord.
Tenant shall pay for any non-Building standard graphics. In addition, Landlord shall initially
input, at Landlord’s expense, a listing of Tenant’s name on the Building’s electronic directory
board located in the main lobby of the Building. Replacement graphics or supplemental directory
entries will be furnished by Landlord upon an order signed by Tenant and at Tenant’s expense.
Landlord shall not be liable for any inconvenience or damage occurring as a result of any error or
omission in any graphics or directory entry.

VI.

     6.01 Condemnation. If more than fifteen percent (15%) of the Premises shall be permanently taken or condemned for any public
purpose, this Lease shall, at the option of either party, forthwith cease and terminate as of the
date of such condemnation or taking. Otherwise, this Lease shall continue in full force and effect
and rental with respect to any portion of the Premises taken or condemned shall be reduced or
abated on the basis of the number of square feet of Net Rentable Area by which the Premises have
been reduced. All proceeds payable from any taking or condemnation of all or any portion of the
Land or the Building shall belong to and be paid as follows: first to Landlord until it receives
the fair market value of the portion of the Land and Building so taken; then to the tenants of the
Building (but no other tenant shall be deemed a third-party beneficiary of this paragraph) pro
rata based upon the respective Net Rentable Area occupied by each tenant prior to such taking until
each tenant receives the fair

-17-

 

market value of all of that portion of its unamortized non-Building
standard improvements, if any, the cost of which were borne solely by such tenant, and such
tenant’s personal property taken; and the remainder of the award shall then be paid to Landlord.

     6.02
Damages from Certain Causes. Landlord shall not be liable or responsible to Tenant for any loss or damage to any property or
person occasioned by theft, fire, act of God, public enemy, injunction, riot, strike,
insurrection, war, court order, requisition or order of governmental body or authority, or any
cause beyond Landlord’s control.

     6.03 Casualty.

     (a) If at any time during the term of this Lease, including any extension or renewal thereof,
the Building and the Premises are damaged by fire or other casualty, then, unless this Lease is
terminated by Landlord as hereinafter provided, Landlord shall be obligated to promptly commence,
and thereafter prosecute with due diligence, the reconstruction, restoration and repair of the
Building and the Premises to a condition substantially equivalent to that existing immediately
prior to the casualty. If the damage renders the Premises inaccessible or untenantable in whole or
in part, Stated Rentals provided for herein shall abate thereafter as to the portion of the
Premises so effected until such time as same is accessible and restored to a tenantable condition,
as reasonably determined by Landlord.

     (b) If (i) the Building is damaged to an extent that Landlord’s good faith estimate of the
cost of reconstruction, restoration and repair thereof exceeds sixty percent (60%) of the
replacement cost of the Building, (ii) the reconstruction, restoration and repair of the Premises
or the Building cannot with reasonable diligence be completed within one hundred eighty (180) days
after the casualty, or (iii) the casualty occurs during the last twelve (12) calendar months of the
term of this Lease, then in any such event Landlord shall have the right, exercisable by written
notice given to Tenant at any time within thirty (30) days after the occurrence of the casualty, to
elect not to reconstruct, restore or repair the Premises, and in such event this Lease shall be
terminated in all respects effective as of the date of the casualty, Stated Rentals shall be
prorated to the date of the casualty, and the parties hereto shall be released from any obligations
thereafter accruing under this Lease (except as otherwise provided herein).

     (c)
Notwithstanding anything contained in this Section 6.03, in no event shall Landlord be
required to expend more to reconstruct, restore and repair the Building than the amount actually
received by Landlord from the proceeds of the property insurance carried by Landlord.

VII.

     7.01 Property Insurance. Landlord shall maintain special form (formerly known as “all-risk”) property insurance on the Building
(excluding non-Building standard leasehold improvements) and on all Building standard leasehold
improvements. Said insurance shall be on a replacement cost basis, and be maintained with an
insurance company authorized to do business in Texas that has a current A.M. Best’s Rating of A-:IX
or better, in amounts sufficient to satisfy any co-insurance requirements and at the expense of
Landlord (but with the same to be included in Operating Expenses) and payments for losses
thereunder shall be made solely to

-18-

 

Landlord. If the annual premiums to be paid by Landlord shall
exceed the standard rates because of Tenant’s operations within or contents of the Premises or
because the Leasehold Improvements to the Premises are above Building standard, Tenant shall
promptly pay the excess amount of the premium upon
request by Landlord (and if necessary, Landlord may allocate the insurance costs of the
Building to give effect to this sentence). Tenant shall maintain at its expense special form
(formerly known as “all-risk”) property insurance, including, but not limited to, vandalism,
malicious mischief, water damage and sprinkler leakage coverage on all of its personal property,
including removable trade fixtures, located in the Premises and on all non-Building standard
Leasehold Improvements, such coverage to be for an amount sufficient to satisfy any co-insurance
requirements, but not less than the full replacement cost of such insured items. Such insurance
shall be maintained with an insurance company authorized to do business in Texas that has a current
A.M. Best’s Rating of A-:IX or better. All such insurance required to be maintained by Tenant
shall name Landlord as an additional insured thereunder and shall provide that it shall not be
cancelable, nor shall the coverage thereunder be reduced, without at least ten (10) days advance
written notice to Landlord. Tenant shall deliver copies of such policies or certificates of
insurance in a form satisfactory to Landlord at the inception of this Lease and within ten (10)
days after any request therefor.

     7.02 Liability Insurance. Landlord and Tenant shall each, at their respective expense, maintain a policy or policies of commercial
general liability insurance written on an occurrence basis with the premiums thereon fully paid on
or before the due dates, issued by and binding upon a solvent insurance company, which is
authorized to do business in Texas that has a current A.M. Best’s Rating of A-:IX or better, such
insurance to afford minimum protection (which may be effected by primary and/or excess coverage) of
not less than $5,000,000.00 each occurrence combined single limit for bodily injury, including
death, and property damage in any one occurrence, provided Tenant shall carry such greater limits
of coverage as Landlord may reasonably request from time to time. All such insurance required to
be maintained by Tenant shall name Landlord and its property manager (currently Hines Interests
Limited Partnership) as additional insureds thereunder and shall provide that it shall not be
cancelable, nor shall the coverage thereunder be reduced, without at least ten (10) days advance
written notice to Landlord. In addition, such insurance policies to be maintained by Tenant shall
have deductible amount or self-insured retention not greater than $25,000.00. Tenant shall deliver
copies of such policies or certificates of insurance in a form satisfactory to Landlord at the
inception of this Lease and within ten (10) days after any request therefor.

     7.03 Hold Harmless  .

     (a) Tenant releases Landlord from all liability for any injury or damage to person or property
occurring in the Premises, and agrees to protect, defend, indemnify and hold Landlord harmless from
and against all liabilities, claims, suits, actions and costs (including reasonable attorneys’ fees
and costs of suit) arising out of or in connection with any such injury or damage, except to the
extent that such injury or damage is attributable to the negligence or willful misconduct of
Landlord, its agents, servants, employees or contractors. Landlord hereby agrees to protect,
defend, indemnify and hold Tenant harmless from and against all liabilities, claims, suits, actions
and costs (including reasonable attorneys’ fees and costs of suit) arising out of or in connection
with any injury or damage to person or property occurring in the Premises, to the

-19-

 

extent that such injury or damage is attributable to the negligence or willful misconduct of
Landlord, its agents, servants, employees or contractors.

     (b) Landlord releases Tenant from all liability for any injury or damage to person or property
occurring in any area of the Building other than the Premises and Landlord agrees to indemnify and
hold Tenant harmless from and against all claims for such injury or damage, except to the extent
that such injury or damage is attributable to the negligence or willful misconduct of Tenant, its
agents, servants, employees, contractors, customers or invitees. Tenant hereby agrees to protect,
defend, indemnify and hold Landlord harmless from and against all liabilities, claims, suits,
actions and costs (including reasonable attorneys’ fees and costs of suit) arising out of or in
connection with any injury or damage to person or property occurring in any area of the Building
other than the Premises, to the extent that such injury or damage is attributable to the negligence
or willful misconduct of the Tenant, its agents, servants, employees, contractors, customers or
invitees.

     (c) The provisions of this Section 7.03 will survive the termination of this Lease with
respect to any claims or liability arising prior to the date of termination.

     7.04 Waiver of Claims and Recovery Rights. Anything in this Lease to the contrary notwithstanding, Landlord and Tenant each, on
behalf of themselves and their respective heirs, successors, legal representatives, assigns and
insurers, hereby (a) waives any and all rights of recovery, claims, actions or causes of action
against the other and its respective officers, directors, partners, shareholders, agents, servants,
employees, guests, licensees or invitees for any loss or damage that may occur to the Premises or
other portion of the Project, or any improvements thereto, or any personal property of such party
therein, by reason of fire, the elements, or any other cause which is required to be insured
against under the terms of the insurance policies referred to in Section 7.01 hereof, REGARDLESS OF
CAUSE OR ORIGIN, INCLUDING NEGLIGENCE OF THE OTHER PARTY HERETO OR ITS RESPECTIVE OFFICERS,
DIRECTORS, PARTNERS, SHAREHOLDERS, AGENTS, SERVANTS, EMPLOYEES, GUESTS, LICENSEES OR INVITEES, and
(b) covenants that no insurer shall hold any right of subrogation against such other party;
provided, however, the waiver set forth in this Section 7.04 shall not apply to any deductibles on
insurance policies carried by Landlord or Tenant or to any coinsurance penalty which Landlord or
Tenant might sustain. If the respective insurer of Landlord and Tenant does not permit such a
waiver without an appropriate endorsement to such party’s insurance policy, then Landlord and
Tenant each shall notify its insurer of the waiver set forth herein and to secure from such insurer
an appropriate endorsement to its respective insurance policy with respect to such waiver.

VIII.

     8.01 Lien for Rent – Intentionally Deleted.

     8.02 Default by Tenant. The occurrence of any one or more of the following events shall constitute an
“Event of Default” under this Lease:

     (a) Tenant shall fail to pay any sum of Rent when due, and such failure shall continue for
five (5) days after written notice to Tenant (provided, however, that after Landlord has given

-20-

 

Tenant written notice of failure to pay Rent when due on two separate occasions, Landlord shall not
be required to give Tenant notice for any subsequent failure);

     (b) Tenant shall fail to execute and acknowledge or otherwise respond in good faith and in
writing within ten (10) days after submission to Tenant of a request for confirmation of the
subordination of this Lease pursuant to Section 11.01(a), confirmation of the subordination of a
mortgage or deed of trust lien to this Lease pursuant to Section 11.01(b) or an estoppel
certificate pursuant to Section 11.02;

     (c) Tenant shall fail in the performance of any of the other covenants or conditions not
included in subparagraphs (a) and (b) of this Section 8.02 which Tenant is required to observe and
to perform under this Lease, and such failure shall continue for twenty (20) days after written
notice to Tenant;

     (d) the interest of Tenant under this Lease shall be levied on under execution or other legal
process; any petition shall be filed by or against Tenant to declare Tenant a bankrupt or to delay,
reduce or modify Tenant’s debts or obligations, or to reorganize or modify Tenant’s capital
structure; Tenant is declared insolvent according to law; any assignment of Tenant’s property shall
be made for the benefit of creditors; or a receiver or trustee is appointed for Tenant or its
property. Notwithstanding the foregoing, if any such levy, execution, legal process, petition,
declaration, assignment or appointment was not initiated by Tenant, any such event shall not be an
Event of Default unless same is not removed or vacated within thirty (30) days from the date of its
creation, service or filing;

     (e) Tenant shall fail to occupy the Premises within fifteen (15) days following the
Commencement Date, shall vacate or abandon the Premises for a period of fifteen (15) or more
continuous days at any time during the term of this Lease or any renewals or extensions thereof, or
if Tenant shall assign this Lease or sublet any portion of the Premises except as specifically
permitted in this Lease; or

     (f) Tenant, if a corporation, shall cease to exist as a corporation in good standing in the
state of its incorporation, or Tenant, if a partnership or other entity, shall be dissolved or
otherwise liquidated.

     8.03 Remedies. Upon the occurrence of any Event of Default, at Landlord’s option, Landlord may (without further notice or grace)
exercise any one or more of the following remedies, in addition to all other rights and remedies
provided at law or in equity:

     (a) Terminate this Lease and immediately repossess the Premises by forcible entry and detainer
suit or otherwise, and be entitled to recover forthwith as damages a sum of money equal to the
total of (i) the cost of recovering the Premises (including reasonable legal fees and
costs of suit), (ii) the unpaid Rent earned at the time of termination, plus interest thereon
at the Default Rate, (iii) the present value (discounted at the rate of ten percent (10%) per
annum) of the balance of the Stated Rentals for the remainder of the term of this Lease, less the
present value (discounted at the same rate) of the fair market rental value of the Premises for
said period, taking into account the period of time during which the Premises is likely to remain
vacant until a new tenant commences payment of rental and the reasonably anticipated out-of-pocket

-21-

 

expenses to be incurred by Landlord to relet the Premises (such as the cost of preparation of the
Premises, leasing commissions, market concessions and reasonable legal fees associated with
occupancy by a new tenant), and (iv) any other sum of money and damages owed by Tenant to Landlord
under the terms of this Lease. The provisions of this paragraph shall survive the expiration or
termination of this Lease. For the purpose of calculating Landlord’s damages under clause (iii) of
this paragraph, Tenant covenants and agrees that:

     (x) it shall be assumed that the Additional Rental for the calendar year in which this
Lease is terminated would be equal to the Additional Rental for the last full calendar year
prior to termination, increased at a rate equal to the average rate of increase (if any) of
Operating Expenses for the three (3) full calendar years preceding the calendar year of
termination (the “Escalation Rate”), and that the Additional Rental for each year
thereafter for the remainder of the term would be equal to the Additional Rental for the
preceding calendar year (calculated in the same manner as for the year of termination),
increased at the Escalation Rate; and

     (y) Landlord may rely upon the average of the determinations of the fair market rental
value of the Premises for the remainder of the term of this Lease made independently and in
writing by three (3) reputable real estate brokers active in the leasing of office space
comparable to the Premises in downtown, Houston, Texas and selected by Landlord in good
faith, and Tenant shall have no right to dispute the value so calculated.

     (b) Terminate Tenant’s right of possession (but not this Lease) and immediately repossess the
Premises by forcible entry and detainer suit or otherwise, without thereby releasing Tenant from
any liability hereunder and without terminating this Lease, and shall be entitled to recover
forthwith as damages a sum of money equal to the total of (i) the cost of recovering the Premises
(including reasonable legal fees and costs of suit), (ii) the unpaid Rent earned at the time of
termination, plus interest thereon at the Default Rate, and (iii) any other sum of money and
damages then owed by Tenant to Landlord under the terms of this Lease. In addition, Tenant shall
remain liable for the payment of all Stated Rentals as same become due under the terms of this
Lease. After regaining possession of the Premises under this Section 8.03(b), Landlord may, but
shall have no obligation to, relet the Premises on such terms and conditions as Landlord in its
sole, good faith judgment deems acceptable, and if the Premises are so relet, Tenant shall receive
credit against the sums otherwise payable to Landlord hereunder only for the amount of the Net
Reletting Income (as hereinafter defined). For the purpose of such reletting Landlord is
authorized to decorate or to make any repairs, changes, alterations or additions in or to Premises
as may be reasonably necessary or desirable. Landlord reserves the right, however (x) to lease any
other space available in the Building prior to offering the Premises for lease, (y) to refuse to
lease the Premises to any potential tenant that does not meet Landlord’s standards and criteria for
leasing other comparable space in the Building, and (z) to
reconfigure the Premises and lease only portions thereof or lease all or part of the Premises
in combination with other space. Any payments due Landlord under this Section 8.03(b) shall be
made upon demand therefor from time to time, and Tenant agrees that Landlord may file suit to
recover any sums falling due under the terms of this Section 8.03(b) from time to time. No
delivery to or recovery by Landlord of any portion due Landlord hereunder shall be any defense in
any action to recover any amount not theretofore reduced to judgment in favor of Landlord,

-22-

 

nor shall any reletting be construed as an election on the part of Landlord to terminate this Lease
unless a written notice of such intention be given to Tenant by Landlord. Notwithstanding any such
reletting without termination, Landlord may at any time thereafter elect to terminate this Lease
for such previous breach. As used above, the term “Net Reletting Income” means the amount
of all rentals actually received by Landlord in respect of a reletting of the Premises during the
term of this Lease, less all of the costs and expenses incurred by Landlord in connection with such
reletting, including, without limitation, leasing commissions, demolition of existing improvements
and installation of new improvements and/or the allowances provided therefor, and legal fees.
Landlord shall not be liable for, nor shall Tenant’s obligations hereunder be diminished because
of, Landlord’s failure to relet the Premises or collect any rentals due in respect of such
reletting.

     (c) Enter upon the Premises by use of a master key, a duplicate key or other peaceable means,
and alter the door locks on all entry doors of the Premises, thereby excluding Tenant and its
officers, principals, agents, employees, contractors, representatives and invitees. If Landlord
elects to so exclude Tenant from the Premises without terminating this Lease or Tenant’s right to
possession of the Premises pursuant to the provisions of this Lease, then Landlord shall be
obligated to provide Tenant a key to re-enter the Premises only upon payment in full of all
delinquent Rent due under this Lease and the curing of all other defaults, if any. If this Lease
or Tenant’s right of possession of the Premises is terminated, Landlord shall have no obligation to
provide Tenant a key to re-enter the Premises, but Landlord will, during Landlord’s regular
business hours, at Landlord’s convenience and upon written request by Tenant, escort Tenant or its
authorized personnel to the Premises to retrieve personal belongings of Tenant’s employees and any
property of Tenant as is not subject to the Landlord’s lien and security interest described in
Section 8.01 hereof. This remedy of Landlord is intended to override and control any conflicting
provisions of the Texas Property Code to the fullest extent permitted by law.

     (d) Landlord may terminate the abatement of Stated Rentals pursuant to Section 2.07, in which
event same shall be immediately due and payable.

     8.04 Landlord’s Right to Cure Defaults. All agreements and provisions to be performed by Tenant under any of the terms of this
Lease shall be at Tenant’s sole cost and expense and without any abatement of rental. If Tenant
shall fail to pay any sum of money, other than Stated Rentals, required to be paid by it hereunder
or shall fail to cure any default and such failure shall continue for ten (10) days after notice
thereof by Landlord, then Landlord may, but shall in no event be obligated to, make any such
payment or perform any such act on Tenant’s account, and such cure by Landlord shall not be deemed
a waiver by Landlord of any of its other remedies or a release of Tenant from any obligations
hereunder. All sums so paid by Landlord and all costs incurred by Landlord in
taking such action shall be deemed additional Rent hereunder and shall be paid to Landlord on
demand, and Landlord shall have (in addition to all other rights and remedies of Landlord) the same
rights and remedies in the event of the non-payment thereof by Tenant as in the case of default by
Tenant in the payment of Rent hereunder.

     8.05 Non-Waiver. Failure of Landlord to declare any default immediately upon occurrence thereof, or delay in taking any action
in connection therewith, shall not waive such

-23-

 

default, but Landlord shall have the right to declare
any such default at any time and take such action as might be lawful or authorized hereunder,
either in law or in equity.

     8.06 Holding Over. If Tenant continues in occupancy of the Premises after expiration or termination of this Lease without the
written consent of Landlord, Tenant shall pay as rent for the holdover period (pro rated on a daily
basis) one hundred fifty percent (150%) of the Stated Rentals payable immediately prior to the
expiration or termination. No holding over by Tenant after the term of this Lease without the
written consent of Landlord shall be construed to extend the term hereof. Any holding over with
the written consent of Landlord shall constitute this a tenancy at sufferance relationship between
Landlord and Tenant, unless specifically stated otherwise in such consent. In the event of any
unauthorized holding over, Tenant shall indemnify Landlord against (i) all claims for damages by
any other lessee to whom Landlord may have leased all or any portion of the Premises and (ii) for
all other losses, costs, and expenses, including reasonable attorneys’ fees incurred by Landlord by
reason of Tenant’s holdover. The provisions of this paragraph shall survive the expiration or
termination of this Lease.

IX.

     9.01 Assignment or Sublease by Tenant.

     (a) Tenant shall not assign this Lease, sublet all or any part of the Premises or allow the
Premises to be used or occupied by others (any such event being referred to herein as a
“Transfer”), or mortgage or otherwise encumber its leasehold estate under this Lease or its
property within the Premises, without Landlord’s prior written consent, such approval not to be
unreasonably withheld, conditioned or delayed.

     (b) Tenant shall give Landlord at least thirty (30) days advance written notice of any
proposed Transfer, stating the anticipated terms thereof. Landlord shall then have a period of
fifteen (15) days following receipt of such notice within which to notify Tenant in writing that
Landlord elects to either (i) to terminate this Lease as to the space so affected, in which event
Tenant shall be relieved of all obligations hereunder as to such space arising from and after such
date, (ii) consent to the proposed Transfer, subject to Landlord’s subsequent written approval of
the proposed transferee or (iii) withhold its consent to the proposed Transfer in accordance with
Section 9.01(c) below.

     (c) Landlord agrees that it will only withhold its consent to a proposed Transfer if one of
the following is true, which Tenant acknowledges would be a reasonable basis for Landlord to
withhold it consent (i) the nature and character of the proposed transferee, its creditworthiness,
business and activities or its intended use of the Premises are not consistent with the standards
of the Building in Landlord’s sole judgment, (ii) the proposed transferee (or any of its
affiliates) is then an occupant of any part of the Building or a party with whom Landlord is then
negotiating to lease space within the Building (unless Landlord is unable to provide such proposed
transferee with space reasonably acceptable to such party), (iii) the proposed occupancy would
impose an extra burden upon the Building systems or Landlord’s ability to provide services to the
other tenants of the Buildings, (iv) the granting of such consent would constitute a default under
any other agreement to which Landlord is a party or by which Landlord is bound or (v) a default or

-24-

 

an Event of Default by Tenant under this Lease is then pending; provided, however, if an uncured
default is then pending Landlord may require that Tenant cure such default as a condition to
Landlord’s consent to such Transfer.

     (d) If Landlord consents to a Transfer, Tenant agrees that fifty percent (50%) of all rental
amounts and other consideration payable to Tenant in respect of the Transfer (net of Tenant’s
out-of-pocket transaction costs in consummating such assignment or sublease, including, without
limitation, brokerage commissions, advertising and legal expenses, a reasonable free rent period
and the reasonable cost of leasehold improvements to the Premises (or a market improvements
allowance in lieu thereof) paid by Tenant in connection with said assignment or subletting) in
excess of the Stated Rentals for the Premises or the portion thereof subject to the Transfer shall
be paid to Landlord as additional rental hereunder immediately upon Tenant’s receipt thereof.
Tenant acknowledges and agrees that, notwithstanding Landlord’s consent to any Transfer, Tenant
shall remain directly and primarily liable for the performance of all the obligations of Tenant
hereunder (including, without limitation, the obligation to pay all Stated Rentals). The consent
by Landlord to any Transfer shall not be deemed in any manner to be a consent to a use not
permitted under Section 1.05(a). Any consent by Landlord to a particular Transfer shall not
constitute Landlord’s consent to any other or subsequent Transfer.

     (e) For purposes of this Section 9.01, if Tenant is a corporation, the shares of which at the
time of execution of this Lease or during the term hereof are or shall be held by fewer than one
hundred (100) persons, and if at any time during the term of this Lease a majority or controlling
amount of shares shall be transferred other than by bequest or inheritance without the prior
written consent of Landlord, then such transfer of shares shall be deemed to be an assignment of
this Lease.

     (f) Notwithstanding the foregoing, it is anticipated that Tenant will soon finalize its public
offering and will become a corporation. The newly incorporated entity will be named Bois d’Arc
Energy Corporation, a Nevada corporation. Upon the effective date of the incorporation, Tenant
represents and warrants that all assets of Tenant, including, without limitation, its leasehold
interest in the Premises granted pursuant to this Lease, will be transferred to Bois d’Arc Energy
Corporation and the new corporation shall assume all of Tenant’s rights and obligations under this
Lease. Tenant shall provide written notice to Landlord when the completion of this incorporation
has occurred and the effective date of such occurrence. Such public offering shall not be a
Transfer that requires Landlord’s consent hereunder.

     9.02 Assignment by Landlord.
Landlord and any successor-in-interest to Landlord shall have the right to transfer and assign, in
whole or in part, its rights and obligations hereunder and in the Project, to any person or entity
acquiring ownership of the Project, and in such event and upon such transfer (any such person or
entity to have the benefit of, and be subject to, the provisions of Section 10.01 and 10.02 hereof)
no further liability or obligation shall thereafter accrue following the date of transfer against
Landlord hereunder, but Landlord will remain liable (to the extent of any net proceeds of such
transfer or assignment) for any accrued and unpaid obligations to Tenant as of the date of transfer
that are not assumed by the successor Landlord.

-25-

 

X.

     10.01 Peaceful Enjoyment. Landlord
covenants that Tenant shall and may peacefully have, hold and enjoy the Premises, subject to the
other terms hereof, provided that Tenant pays the rental and other sums herein recited to be paid
by Tenant and performs all of Tenant’s covenants and agreements herein contained. It is understood
and agreed that this covenant and any and all other covenants of Landlord contained in this Lease
shall be binding upon Landlord and its successors only with respect to breaches occurring during
its and their respective ownership of the Landlord’s interest hereunder.

     10.02 Limitation of Landlord’s Personal Liability. Subject to the provisions of Section 9.02, Tenant agrees to look solely to
Landlord’s interest (or its successor’s interest) in the Project for the recovery of any judgment
against Landlord, it being agreed that neither Landlord (and its partners (general or limited),
officers, directors, and shareholders) nor any mortgagee shall ever be personally liable for any
such judgment. In addition, Tenant also agrees that Tenant shall not be entitled to recover from
Landlord nor any of its agents, employees, officers, partners, servants or shareholders any
indirect, special or consequential damages Tenant may incur as a result of a default under this
Lease or other action by Landlord, its agents, employees, officers, partners, servants or
shareholders. The provisions contained in the foregoing sentences are not intended to, and shall
not, limit any right that Tenant might otherwise have to (i) obtain injunctive relief against
Landlord or Landlord’s successors in interest, or (ii) any suit or action in connection with
enforcement or collection of amounts which may become owing or payable under or on account of
insurance maintained by Landlord.

XI.

     11.01 Subordination.

     (a) Tenant covenants and agrees with Landlord that this Lease is subject and subordinate to
any mortgage, deed of trust, ground lease and/or security agreement which may now or hereafter
encumber the Project or any interest of Landlord therein, and to any advances
made on the security thereof and to any and all increases, renewals, modifications,
consolidations, replacements and extensions thereof. This clause shall be self-operative and no
further instrument of subordination need be required by any owner or holder of any such ground
lease, mortgage, deed of trust or security agreement. In confirmation of such subordination and
attornment, however, at Landlord’s written request Tenant shall execute any appropriate certificate
or instrument that Landlord or any Interest Holder may request within ten (10) days after being
requested to do so. In the event of (i) the enforcement by the ground lessor, the mortgagee, the
trustee, the beneficiary or the secured party under any such ground lease, mortgage, deed of trust
or security agreement (any such party being herein referred to as “Interest Holder”) of the
remedies provided for by law or by such ground lease, mortgage, deed of trust or security
agreement, or (ii) the acceptance of a deed or assignment in lieu thereof by an Interest Holder,
Tenant, upon written request of the Interest Holder or any person or party succeeding to the
interest of Landlord as a result of such enforcement, or deed or assignment in lieu thereof, will
attorn to and automatically become the tenant of such Interest Holder or successor in interest
without any change in the terms or other provisions of this Lease; provided, however, that such
Interest Holder or successor in interest shall not be (A) liable for any act or

-26-

 

omission of any prior landlord (including Landlord), (B) liable for the return of any security deposit unless such
deposit has been delivered to Interest Holder by Landlord or is an escrow fund available to
Interest Holder, (C) subject to any offsets, claims, counterclaims or defenses that Tenant might
have against any prior landlord (including Landlord), (D) bound by any rent or additional rent that
Tenant might have paid for more than the current month to any prior landlord (including Landlord),
(E) bound by any amendment, modification, or termination of the Lease made without Interest
Holder’s consent, (F) personally liable under the Lease, Interest Holder’s liability thereunder
being limited to its then interest, if any, in the Project, (G) bound by any provision in the Lease
which obligates Landlord to erect or complete any building or to perform any construction work or
to make any improvements to the Premises or to expand or rehabilitate any existing improvements or
to restore any improvements following any casualty or taking or to make a future capital
contribution to Tenant or to apply proceeds of casualty insurance or eminent domain awards other
than as provided in the deed of trust or ground lease, as applicable, which shall govern over any
conflicting provision hereof with respect thereto, or (H) bound by any notice of termination given
by Landlord to Tenant without Interest Holder’s prior written consent thereto. Upon request by
such Interest Holder or successor in interest, whether before or after the enforcement of its

subordinate to all matters of record in Harris County, Texas.

     (b) Notwithstanding anything to the contrary set forth in Section 11.01(a), above, any
Interest Holder may at any time subordinate its lien to this Lease in whole or in part, without any
need to obtain Tenant’s consent, and without regard to their respective dates of execution,
delivery or recordation. In that event, to the extent set forth in such document, the Interest
Holder shall have the same rights with respect to this Lease as would have existed if this Lease
had been executed, and a memorandum thereof recorded, prior to the execution, delivery and
recordation of the mortgage or deed of trust. In confirmation of such subordination, however,
Tenant shall execute any appropriate certificate or instrument that Landlord or the Interest Holder
may request within ten (10) days after being requested to do so.

Landlord a certificate signed by a Tenant certifying (a) that the lease is in full force and effect
and unmodified (or if there have been modifications, that the same is in full force and effect as
modified and stating the modifications), (b) as to the Commencement Date and the date through which
Base Rental, Estimated Additional Rental and Additional Rental have been paid, (c) that Tenant has
accepted possession of the Premises and that any improvements required by the terms of this Lease
to be made by Landlord have been completed to the satisfaction of Tenant, (d) that except as stated
in the certificate no rental under this Lease has been paid more than thirty (30) days in advance
of its due date, (e) that the address for notices to be sent to Tenant is as set forth in this
Lease (or has been changed by notice duly given and is as set forth in the certificate), (f) that
except as stated in the certificate, Tenant, as of the date of such certificate, has no charge,
lien, or claim of offset under this Lease or otherwise against rentals or other charges due or to
become due hereunder, (g) that except as stated in the certificate, Landlord is not then in default
under this Lease, (h) that there are no renewal or extension options, purchase options, rights of

other matters as may be requested by Landlord. Any

such certificate may be relied upon by any
existing or prospective Interest Holder or purchaser of the Building or the Land or any part
thereof or interest of Landlord therein.

     11.03 Right to Cure Landlord’s Default. Prior to exercising any remedy for an alleged default by Landlord hereunder, Tenant
will give written notice to any Interest Holder of which Tenant has notice specifying the nature of
the alleged default. Each Interest Holder shall have the right (but not the obligation) for a
period of sixty (60) days to cure or remedy such default (or if the Interest Holder cannot
reasonably cure or remedy such default within said sixty (60) day period, such longer period as is
necessary to allow the Interest Holder to effect such cure or remedy, provided that the Interest
Holder commences its good faith efforts to cure or remedy such default within said sixty (60) day
period), and Tenant will accept such curative or remedial action taken by the Interest Holder with
the same effect as if such action had been taken by Landlord.

defaults in the performance of any of the terms, agreements or conditions contained in this Lease
and the other party places the enforcement of this Lease, or any part thereof, or the collection of
any rental due or to become due hereunder, or recovery of the
possession of the Premises, in the hands of an attorney who files suit upon the same, and
should such non-defaulting party prevail in such suit, the defaulting party agrees to pay the other
party’s reasonable legal fees.

     12.04 DTPA Inapplicable. It is the intent of Landlord and Tenant that the provisions of the Texas Deceptive Trade Practices-Consumer
