corporation (the Company), upon the terms and conditions set forth herein 100,000 shares of

three months after cessation of the Holders relationship with the Company or an Affiliate
thereof, other than for cause unless cessation is due to death or total disability, in which case
the Warrant shall terminate twelve months after cessation of such relationship, or (iv) five years
after cessation of the Holders relationship with the Company or an Affiliate thereof in the event
of a Reclassification, Reorganization, or Merger event, as defined in section 6, provided, that the
Holders employment is terminated within twelve months following the date of such Reclassification,
Reorganization, or Merger event (the Exercise Period). This Warrant may be exercised during the Exercise Period, either in whole or in part, by the
surrender of this Warrant (with the election at the end hereof duly executed) to the Company at its
office at 14860 Montfort Dr., Suite 250, Dallas, Texas 75254, or at such other place as is
designated in writing by the Company, together with a certified or bank cashiers check payable to
the order of the Company in an amount equal to the product of the Exercise Price and the number of
Warrant Shares for which this Warrant is being exercised. The Warrant may be exercised by the delivery of: (a) Cash, personal check (unless at the time of exercise the Board of Directors determines
otherwise), or bank certified or cashiers checks; (b) Unless the Board of Directors in their sole discretion determine otherwise, shares of the
capital stock of the Company held by you having a fair market value at the time of exercise, as
determined in good faith by the Board of Directors, equal to the exercise price; (c) Unless the Board of Directors in their sole discretion determine otherwise, a properly
executed Notice of Exercise, together with instructions to the Company to withhold from the shares
that would otherwise be issued upon exercise that number of shares having a fair market value equal
to the option exercise price; or (d) Unless the Board of Directors in their sole discretion determine otherwise, a properly
executed Notice of Exercise, together with irrevocable instructions to a broker to promptly deliver
to the Company the amount of sale or loan proceeds to pay the exercise price. Section 2Rights Upon Exercise; Delivery of Securities. Upon each exercise of the Holders rights to purchase Warrant Shares, the Holder shall be
deemed to be the holder of record of the Warrant Shares, notwithstanding that the transfer books of
the Company shall then be closed or certificates representing the Warrant Shares with respect to
which this Warrant was exercised shall not then have been actually delivered to the Holder. As
soon as practicable after each such exercise of this Warrant, the Company shall issue and deliver
to the Holder a certificate or certificates representing the Warrant Shares issuable upon such
exercise, registered in the name of the Holder or its designee. If this Warrant should be
exercised in part only, the Company shall, upon surrender of this Warrant for cancellation, execute
and deliver a Warrant evidencing the right of the Holder to purchase the balance of the aggregate
number of Warrant Shares purchasable hereunder as to which this Warrant has not been exercised or
assigned. Section 3Transferability. Except as otherwise expressly provided herein, this Warrant shall not be transferable. This
Warrant may be exchanged, at the option of the Holder thereof, for another Warrant, or other
Warrants of different denominations, of like tenor and representing in the aggregate the right to
purchase a like number of Warrant Shares (or portions thereof), upon surrender to the Company or
its duly authorized agent. Section 4Reservation of Shares. The Company shall at all times reserve and keep available out of its authorized and unissued
Common Stock, solely for the purpose of providing for the exercise of the Warrants, such number of
shares of Common Stock as shall, from time to time, be sufficient therefor. The Company represents
that all shares of Common Stock issuable upon exercise of this Warrant are duly authorized and,
upon receipt by the Company of the full payment for such Warrant Shares, will be validly issued,
fully paid, and nonassessable, without any personal -80-

liability attaching to the ownership thereof and will not be issued in violation of any
preemptive or similar rights of stockholders. Section 5Antidilution. (a) In the event that the Company shall at any time after the Initial Exercise Date: (i)
declare a dividend on the outstanding Common Stock payable in shares of its capital stock; (ii)
subdivide the outstanding Common Stock; (iii) combine the outstanding Common Stock into a smaller
number of shares; or (iv) issue any shares of its capital stock by reclassification of the Common
Stock (including any such reclassification in connection with a consolidation or merger in which
the Company is the continuing corporation), then, in each case, the Exercise Price per Warrant
Share in effect at the time of the record date for the determination of stockholders entitled to
receive such dividend or distribution or of the effective date of such subdivision, combination, or
reclassification shall be adjusted so that it shall equal the price determined by multiplying such
Exercise Price by a fraction, the numerator of which shall be the number of shares of Common Stock
outstanding immediately prior to such action, and the denominator of which shall be the number of
shares of Common Stock outstanding after giving effect to such action. Such adjustment shall be
made successively whenever any event listed above shall occur and shall become effective at the
close of business on such record date or at the close of business on the date immediately preceding
such effective date, as applicable. (b) All calculations under this Section 5 shall be made to the nearest cent or to the nearest
one-hundredth of a share, as the case may be. (c) In any case in which this Section 5 shall require that an adjustment in the number of
Warrant Shares be made effective as of a record date for a specified event, the Company may elect
to defer, until the occurrence of such event, issuing to the Holder, if the Holder exercised this
Warrant after such record date, the Warrant Shares, if any, issuable upon such exercise over and
above the number of Warrant Shares issuable upon such exercise on the basis of the number of shares
of Common Stock in effect prior to such adjustment; provided, however, that the Company shall
deliver to the Holder a due bill or other appropriate instrument evidencing the Holders right to
receive such additional shares of Common Stock upon the occurrence of the event requiring such
adjustment. (d) Whenever there shall be an adjustment as provided in this Section 5, the Company shall
within 15 days thereafter cause written notice thereof to be sent by registered mail, postage
prepaid, to the Holder, at its address as it shall appear in the books and records of the Company,
which notice shall be accompanied by an officers certificate setting forth the number of Warrant
Shares issuable and the Exercise Price thereof after such adjustment and setting forth a brief
statement of the facts requiring such adjustment and the computation thereof, which officers
certificate shall be conclusive evidence of the correctness of any such adjustment absent manifest
error. (e) The Company shall not be required to issue fractions of shares of Common Stock or other
capital stock of the Company upon the exercise of this Warrant. If any fraction of a share of
Common Stock would be issuable on the exercise of this Warrant (or specified portions thereof), the
Company shall pay lieu of such fraction an amount in cash equal to the same fraction of the average
closing sale price (or average of the closing bid and asked prices, if closing sale price is not
available) of Common Stock for the 10 trading days ending on and including the date of exercise of
this Warrant. (f) No adjustment in the Exercise Price per Warrant Share shall be required if such adjustment
is less than $.05; provided, however, that any adjustments which by reason of this Section 5 are
not required to be made shall be carried forward and taken into account in any subsequent
adjustment. (g) Whenever the Exercise Price payable upon exercise of this Warrant is adjusted pursuant to
subsection (a) above, the number of Warrant Shares issuable upon exercise of this Warrant shall
simultaneously be adjusted by multiplying the number of Warrant Shares theretofore issuable upon
exercise of this Warrant by the Exercise Price in effect on the date hereof and dividing the
product so obtained by the Exercise Price, as adjusted. Section 6Reclassification; Reorganization; Merger; Change of Control. -81-

(a) Cash, Stock, or Other Property for Stock. Except as provided in Section 6(b)
hereof, upon a merger (other than a merger of the Company in which the holders of Common Stock
immediately prior to the merger have the same proportionate ownership of common stock in the
surviving corporation immediately after the merger), consolidation, acquisition of property or
stock, separation, reorganization (other than mere reincorporation or creation of a holding
company), or liquidation of the Company (each, an event), as a result of which the stockholders
of the Company receive cash, stock, or other property in exchange for, or in connection with, their
shares of Common Stock, any warrant granted hereunder shall terminate, but the time during which
such warrants may be exercised shall be accelerated as follows: the Holder shall have the right
immediately prior to any such event to exercise such Holders option in whole or in part whether or
not the vesting requirements set forth in Section 1 have been satisfied. (b) Conversion of Options on Stock for Exchange Stock. If the stockholders of the
Company receive capital stock of another corporation (Exchange Stock) in exchange for their
shares of Common Stock in any transaction involving a merger (other than a merger of the Company in
which the holders of Common Stock immediately prior to the merger have the same proportionate
ownership of common stock in the surviving corporation immediately after the merger),
consolidation, acquisition of property or stock, separation, or reorganization (other than mere
reincorporation or creation of a holding company), all warrants granted hereunder shall be
converted into warrants to purchase shares of Exchange Stock unless the Company and corporation
issuing the Exchange Stock, in their sole discretion, determine that any or all such warrants
granted hereunder shall not be converted into warrants to purchase shares of Exchange Stock but
instead shall terminate in accordance with the provisions of Section 6(a) hereof. The amount and
price of converted warrants shall be determined by adjusting the amount and price of the warrants
granted hereunder in the same proportion as used for determining the number of shares of Exchange
Stock the holders of the Common Stock receive in such merger, consolidation, acquisition,
separation, or reorganization. Unless the Board determines otherwise, the converted warrants shall
be fully vested whether or not the vesting requirements set forth in Section 1 have been satisfied. (c) In case of any capital reorganization, other than in the cases referred to in Section 5(a)
hereof, or the consolidation or merger of the Company with or into another corporation (other than
a merger or consolidation in which the Company is the continuing corporation and which does not
result in any reclassification of the outstanding shares of Common Stock or the conversion of such
outstanding shares of Common Stock into shares of other stock or other securities or property), or
in the case of any sale, lease, or conveyance to another corporation of the property and assets of
any nature of the Company as an entirety or substantially as an entirety (such actions being
hereinafter collectively referred to as Reorganizations), there shall thereafter be deliverable
upon exercise of this Warrant (in lieu of the number of Warrant Shares theretofore deliverable) the
number of shares of stock or other securities or property to which a holder of the respective
number of Warrant Shares which would otherwise have been deliverable upon the exercise of this
Warrant would have been entitled upon such Reorganization if this Warrant had been exercised in
full immediately prior to such Reorganization. In case of any Reorganization, appropriate
adjustment, as determined in good faith by the Board of Directors of the Company, shall be made in
the application of the provisions herein set forth with respect to the rights and interests of the
Holder so that the provisions set forth herein shall thereafter be applicable, as nearly as
possible, in relation to any shares or other property thereafter deliverable upon exercise of this
Warrant. Any such adjustment shall be made by, and set forth in, a supplemental agreement between
the Company, or any successor thereto, and the Holder, with respect to this Warrant, and shall for
all purposes hereof conclusively be deemed to be an appropriate adjustment. The Company shall not
effect any such Reorganization unless, upon or prior to the consummation thereof, the successor
corporation, or if the Company shall be the surviving corporation in any such Reorganization and is
not the issuer of the shares of stock or other securities or property to be delivered to holders of
shares of the Common Stock outstanding at the effective time thereof, then such issuer, shall
assume by written instrument the obligation to deliver to the Holder such shares of stock,
securities, cash, or other property as such Holder shall be entitled to purchase in accordance with
the foregoing provisions. In the event of sale, lease, or conveyance or other transfer of all or
substantially all of the assets of the Company as part of a plan for liquidation of the Company,
all rights to exercise this Warrant shall terminate 30 days after the Company gives written notice
to the Holder that such sale or conveyance or other transfer has been consummated. -82-

(d) In case of any reclassification or change of the shares of Common Stock issuable upon
exercise of this Warrant (other than a change in par value or from a specified par value to no par
value, or as a result of a subdivision or combination, but including any change in the shares into
two or more classes or series of shares), or in case of any consolidation or merger of another
corporation into the Company in which the Company is the continuing corporation and in which there
is a reclassification or change (including a change to the right to receive cash or other property)
of the shares of Common Stock (other than a change in par value, or from no par value to a
specified par value, or as a result of a subdivision or combination, but including any change in
the shares into two or more classes or series of shares), the Holder or holders of this Warrant
shall have the right thereafter to receive upon exercise of this Warrant solely the kind and amount
of shares of stock and other securities, property, cash, or any combination thereof receivable upon
such reclassification, change, consolidation, or merger by a holder of the number of Warrant Shares
for which this Warrant might have been exercised immediately prior to such reclassification,
change, consolidation, or merger. Thereafter, appropriate provision shall be made for adjustments
which shall be as nearly equivalent as practicable to the adjustments in Section 5. (e) The above provisions of this Section 6 shall similarly apply to successive
reclassifications and changes of shares of Common Stock and to successive consolidations, mergers,
sales, leases, or conveyances. Section 7Notice of Certain Events. In case at any time the Company shall propose: (a) to pay any dividend or make any distribution on shares of Common Stock in shares of Common
Stock or make any other distribution (other than regularly scheduled cash dividends which are not
in a greater amount per share than the most recent such cash dividend) to all holders of Common
Stock; or (b) to issue any rights, warrants, or other securities to all holders of Common Stock
entitling them to purchase any additional shares of Common Stock or any other rights, warrants, or
other securities; or (c) to effect any reclassification or change of outstanding shares of Common Stock or any
consolidation, merger, sale, lease, or conveyance of property, as described in Section 6; or (d) to effect any liquidation, dissolution, or winding-up of the Company; or (e) to take any other action which would cause an adjustment to the Exercise Price per Warrant
Share; then, and in any one or more of such cases, the Company shall give written notice thereof by
registered mail, postage prepaid, to the Holder at the Holders address as it shall appear in the
Warrant Register, mailed at least 15 days prior to: (i) the date as of which the holders of record
of shares of Common Stock to be entitled to receive any such dividend, distribution, rights,
warrants, or other securities are to be determined; (ii) the date on which any such
reclassification, change of outstanding shares of Common Stock, consolidation, merger, sale, lease,
conveyance of property, liquidation, dissolution, or winding-up is expected to become effective and
the date as of which it is expected that holders of record of shares of Common Stock shall be
entitled to exchange their shares for securities or other property, if any, deliverable upon such
reclassification, change of outstanding shares, consolidation, merger, sale, lease, conveyance of
property, liquidation, dissolution, or winding-up; or (iii) the date of such action which would
require an adjustment to the Exercise Price per Warrant Share. Section 8Charges and Taxes. The issuance of any shares or other securities upon the exercise of this Warrant and the
delivery of certificates or other instruments representing such shares or other securities shall be
made without charge to the Holder for any tax or other charge in respect of such issuance. The
Company shall not, however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of any certificate in a name other than that of the
Holder and the Company shall not be required to issue or deliver any such certificate unless and
until the person or persons requesting the issue thereof shall have paid to the Company the amount
of such tax or shall have established to the satisfaction of the Company that such tax has been
paid. Section 9Periodic Reports. -83-
