     1.   Duration and Exercise of Warrant; Limitation Exercise Payment of
          ----------------------------------------------------------------
          Taxes.
          -----

          1.1  Duration and Exercise of Warrant.
               --------------------------------

     (a) Subject to Section 1.2, this Warrant may be exercised to purchase (i)
50% of the underlying shares from and after 9:00 A.M. New York City time on
January 24, 2002 (the "First Exercise Date") and (ii) 50% of the underlying
shares on January 24, 2003 (the "Second Exercise Date").  Each of the First
Exercise Date and the Second Exercise Date are hereinafter referred to from time
to time, as applicable, as the "Exercise Date" and collectively from time to
time as the "Exercise Dates").  The Company shall give prompt notice to the
Warrantholder of the Exercise Date in accordance with Section 7.6.  This Warrant
expires at 5:00 P.M., New York City time on January 24, 2011 (the "Expiration
Date").

     (b)  The rights represented by this Warrant may be exercised by the
Warrantholder of record, in whole, or from time to time in part, by (a)
surrender of this Warrant, accompanied by either the Exercise Form annexed
hereto, or if the Warrantholder decides to exercise the Warrant pursuant to the
broker-assisted cashless exercise program instituted by the Company, an
applicable exercise form provided by the Company (the "Exercise Form") duly
executed by the Warrantholder of record and specifying the number of Warrant
Shares to be purchased, to the Company at the office of the Company located at
3232 McKinney Avenue, Suite 1000, Dallas, Texas 75204 (or such other office or
agency of the Company as it may designate by notice to the Warrantholder at the
address of such Warrantholder appearing on the books of the Company) during
normal business hours on any day (a "Business Day") other than a Saturday,
Sunday or a day on which the New York Stock Exchange is authorized to close or
on which the Company is otherwise closed for business (a "Nonbusiness Day") on
or after 9:00 A.M. New York City time on the applicable Exercise Date but not
later than 5:00 P.M., New York City time, on the Expiration Date (or 5:00 P.M.,
New York City time, on the next succeeding Business Day, if the Expiration Date
is a Nonbusiness Day), (b) delivery of payment to the Company in cash or by
certified or official bank check in New York Clearing House Funds, of the
Exercise Price for the number of Warrant Shares specified in the Exercise Form
(such payment may be made by the Warrantholder directly or by a designated
broker pursuant to the broker-assisted cashless exercise program instituted by
the Company) and (c) such documentation as to the identity and authority of the
Warrantholder as the Company may reasonably request.  Such Warrant Shares shall
be deemed by the Company to be issued to the Warrantholder as the record holder
of such Warrant Shares as of the close of business on the date on which this
Warrant shall have been surrendered and payment made for the Warrant Shares as
aforesaid. Certificates for the Warrant Shares specified in the Exercise Form
shall be delivered to the Warrantholder (or designated broker, as the case may
be) as promptly as practicable, and in any event within 10 business days,
thereafter.  The stock certificates so delivered shall be in denominations of at
least 1,000 shares each or such other denomination as may be specified by the
Warrantholder and agreed upon by the Company, and shall be issued in the name of
the Warrantholder or such other name as shall be designated in the Exercise
Form.  If this Warrant shall have been exercised only in part, the Company
shall, at the time of delivery of the certificates for the Warrant Shares,
deliver to the Warrantholder (or designated broker, as the case may be) a new
Warrant evidencing the rights to

                                       2
<PAGE>

purchase the remaining Warrant Shares, which new Warrant shall in all other
respects be identical with this Warrant. No adjustments or payments shall be
made on or in respect of Warrant Shares issuable on the exercise of this Warrant
for any cash dividends paid or payable to holders of record of Common Stock
prior to the date as of which the Warrantholder shall be deemed to be the record
holder of such Warrant Shares.

     (c) With the consent of the Compensation Committee, and subject at all
times to, and only to the extent, if any, permitted under and in accordance
with, laws and regulations and other binding obligations or provisions
applicable to the Company, the Company may make a loan to the Warrantholder with
respect to the exercise of the Warrant, including the payment by the
Warrantholder of any or all federal, state and local income or other taxes due
in connection with any exercise.  The interest on such loan shall be the
Company's cost of money plus an additional 0.5% at the time the loan is made and
such loan shall be made with recourse against the Warrantholder. The
Compensation Committee shall have the full authority to determine any other
terms and provisions of such a loan.

     1.2  Vesting and Exercise.  Once vested, this Warrant may be exercised as
          --------------------
to such vested portion whether or not at the time of such exercise the
Warrantholder is an employee of (or consultant to) the Company (or one or more
of its subsidiaries); however, this Warrant shall automatically terminate as to
any unvested portion at any such time as the Warrantholder is no longer employed
by (or a consultant to) the Company (or any of its subsidiaries).  If this
Warrant is not exercised prior to 5:00 P.M. on the Expiration Date (or the next
succeeding Business Day, if the Expiration Date is a Nonbusiness Day), this
Warrant, or any new Warrant issued pursuant to Section 1.1, shall cease to be
exercisable and shall become void and all rights of the Warrantholder hereunder
shall cease.  This Warrant shall not be exercisable, and no Warrant Shares shall
be issued hereunder, prior to 9:00 A.M., New York City time, on the applicable
Exercise Date.

     1.3  Payment of Taxes.  The issuance of certificates for Warrant Shares
          ----------------
shall be made without charge to the Warrantholder for any stock transfer or
other issuance tax in respect thereto; provided, however, that the Warrantholder
                                       --------  -------
shall be required to pay any and all taxes which may be payable in respect to
any transfer involved in the issuance and delivery of any certificates for
Warrant Shares in a name other than that of the then Warrantholder as reflected
upon the books of the Company.

     1.4  Divisibility of Warrant.  This Warrant may be divided into warrants
          -----------------------
representing one Warrant Share or multiples thereof, upon surrender at the
principal office of the Company on any Business Day, without charge to any
Warrantholder, except as provided below.  The Warrantholder will be charged for
reasonable out-of-pocket costs incurred by the Company in connection with the
division of this Warrant into Warrants representing fewer than one thousand
(1,000) Warrant Shares. Upon any such division, the Warrants may be transferred
of record to a name other than that of the Warrantholder of record; provided,
                                                                    --------
however, that the Warrantholder shall be required to pay any and all transfer
-------
taxes with respect thereto.

                                       3
<PAGE>

     2.   Reservation and Listing of Shares, Etc.
          --------------------------------------

     All Warrant Shares which are issued upon the exercise of the rights
represented by this Warrant shall, upon issuance and payment of the Exercise
Price, be validly issued, fully paid and nonassessable and free from all taxes,
liens, security interests, charges and other encumbrances with respect to the
issue thereof other than taxes in respect of any transfer occurring
contemporaneously with such issue.  During the period within which this Warrant
may be exercised, the Company shall at all times have authorized and reserved,
and keep available free from preemptive rights, a sufficient number of shares of
Common Stock to provide for the exercise of this Warrant, and shall at its
expense use its best efforts to procure such listing thereof (subject to
official notice of issuance) as then may be required on all stock exchanges on
which the Common Stock is then listed or on the Nasdaq National Market.  The
Company shall, from time to time, take all such action as may be required to
assure that the par value per share of the Warrant Shares is at all times equal
to or less than the then effective Exercise Price.

     3.   Exchange, Loss or Destruction of Warrant.
          ----------------------------------------

     If permitted by Section 1.4 and in accordance with the provisions thereof,
upon surrender of this Warrant to the Company with a duly executed instrument of
assignment and funds sufficient to pay any transfer tax, the Company shall,
without charge, execute and deliver a new Warrant of like tenor in the name of
the assignee named in such instrument of assignment and this Warrant shall
promptly be canceled.  Upon receipt by the Company of evidence satisfactory to
it of the loss, theft, destruction or mutilation of this Warrant, and, in the
case of loss, theft or destruction, of such bond or indemnification as the
Company may reasonably require, and, in the case of such mutilation, upon
surrender and cancellation of this Warrant, the Company will execute and deliver
a new Warrant of like tenor.  The term "Warrant" as used herein includes any
Warrants issued in substitution or exchange of this Warrant.

     4.   Ownership of Warrant.
          --------------------

     The Company may deem and treat the person in whose name this Warrant is
registered as the holder and owner hereof (notwithstanding any notations of
ownership or writing hereon made by anyone other than the Company) for all
purposes and shall not be affected by any notice to the contrary, until
presentation of this Warrant for registration of transfer as provided in Section
1.1 or in Section 3.

     5.   Certain Adjustments.
          -------------------

     The Exercise Price at which Warrant Shares may be purchased hereunder, and
the number of Warrant Shares to be purchased upon exercise hereof, are subject
to change or adjustment as follows:

     5.1  The number of Warrant Shares purchasable upon the exercise of this
Warrant and the Exercise Price shall be subject to adjustment as follows:

                                       4
<PAGE>

     (a)  In case the Company shall (i) pay a dividend in shares of Common Stock
or make a distribution in shares of Common Stock, (ii) subdivide its outstanding
shares of Common Stock into a greater number of shares of Common Stock, (iii)
combine its outstanding shares of Common Stock into a smaller number of shares
of Common Stock or (iv) issue by reclassification of its shares of Common Stock
other securities of the Company (including any such reclassification in
connection with a consolidation or merger in which the Company is the surviving
corporation), the number of Warrant Shares purchasable upon exercise of this
Warrant (and the Exercise Price) shall be adjusted so that the Warrantholder
shall be entitled to receive (for the aggregate Exercise Price) the kind and
number of Warrant Shares or other securities of the Company that he would have
owned or have been entitled to receive after the happening of any of the events
described above, had this Warrant been exercised immediately prior to the
happening of such event or any record date with respect thereto.  An adjustment
made pursuant to this paragraph (a) shall become effective immediately after the
effective date of such event retroactive to the record date, if any, for such
event.

     (b)  In case the Company shall:

          (i)   issue rights, options or warrants to all holders of its
          outstanding Common Stock, without any charge to such holders,
          entitling them to subscribe for or purchase shares of Common Stock at
          a price per share which is lower at the record date for the
          determination of stockholders entitled to receive such rights, options
          or warrants than the then current market price per share of Common
          Stock, or

          (ii)  distribute to all holders of its shares of Common Stock
          evidences of its indebtedness or assets (excluding cash dividends or
          distributions payable out of consolidated earnings or earned surplus
          and dividends or distributions referred to in paragraph (a) of this
          Section 5.1) or rights, options or warrants, or convertible or
          exchangeable securities, containing the right to subscribe for or
          purchase shares of Common Stock,

appropriate adjustments shall be made to the number of Warrant Shares
purchasable upon the exercise of the Warrant and/or the Exercise Price in order
to preserve the relative rights and interests of the Warrantholders, such
adjustments to be made by the good faith determination of the Board of Directors
of the Company.

     5.2  Voluntary Adjustment by the Company.  The Company may, at its option,
          -----------------------------------
at any time during the term of the Warrants, reduce the then current Exercise
Price to any amount, consistent with applicable law, deemed appropriate by the
Board of Directors of the Company.

     5.3  Notice of Adjustment.  Whenever the number of Warrant Shares or the
          --------------------
Exercise Price of such Warrant Shares is adjusted, as herein provided, the
Company shall promptly mail first class, postage prepaid, to all Warrantholders,
notice of such adjustment.

                                       5
<PAGE>

     5.4  No Adjustment for Cash Dividends.  No adjustment in respect of any
          --------------------------------
cash dividends shall be made during the term of this Warrant or upon the
exercise of this Warrant.

     5.5  Preservation of Purchase Rights Upon Merger, Consolidation, etc.  In
          ---------------------------------------------------------------
case of any consolidation of the Company with or merger of the Company into
another corporation or in case of any sale, transfer or lease to another
corporation of all or substantially all of the property of the Company, the
Company or such successor or purchasing corporation, as the case may be, shall
execute with the Warrantholders an agreement that the Warrantholders shall have
the right thereafter upon payment of the Exercise Price in effect immediately
prior to such action to purchase upon exercise of this Warrant the kind and
amount of shares and other securities and property that such holder would have
owned or have been entitled to receive after the happening of such
consolidation, merger, sale, transfer or lease had this Warrant been exercised
immediately prior to such action; provided, however, that no adjustment in
                                  --------  -------
respect of cash dividends, interest or other income on or from such shares or
other securities and property shall be made during the term of this Warrant or
upon the exercise of this Warrant.  Such agreement shall provide for
adjustments, which shall be as nearly equivalent as practicable to the
adjustments provided for in this Section 5.  The provisions of this Section 5.5
shall apply similarly to successive consolidations, mergers, sales, transfers or
leases.

     6.   Registration Rights of Warrant Shares on Form S-8
          -------------------------------------------------

     On or prior to January 31, 2002, the Company shall file a registration
statement covering the Warrant Shares on a Form S-8, which registration
statement shall be effective upon the filing thereof. The Company shall use its
best efforts to keep such Form S-8 current and effective until the earlier of
the Expiration Date or the date this Warrant has been exercised in full.  The
Company shall use its best efforts to list the Warrant Shares on any securities
exchange (or on the Nasdaq National Market) on which other shares of Common
Stock are listed.
