	1. 	Exercise.

1.1 Procedure for Exercise of Warrant.
Subject to the terms and conditions of this Warrant Certificate, the Holder may
exercise this Warrant by delivering the following to the principal office of the
Company in accordance with Section 5.1 hereof: 

	 	(a) 	
      a duly executed Notice of Exercise in substantially the
      form attached as Schedule A,

	 	 	 
	 	(b) 	
      either (i) a written certification that the Holder is not
      a U.S. person, as defined under Regulation S of the Securities Act, and
      that the Warrant is not being exercised on behalf of a U.S. person, which
      written certificate may be contained in the Notice of Exercise delivered
      pursuant to sub-paragraph (a) above; or (ii) a written opinion of counsel
      to the effect that the Warrant and the Shares have been registered under
      the Securities Act or are exempt from registration thereunder;

	 	 	 
	 	(c) 	
      payment of the Exercise Price then in effect for each of
      the Shares being purchased, as designated in the Notice of Exercise,
      and

	 	 	 
	 	(d) 	
      this Warrant.

Payment of the Exercise Price may be in cash, certified or
official bank check payable to the order of the Company, or wire transfer of
funds to the Company’s account (or any combination of any of the foregoing) in
the amount of the Exercise Price for each share being purchased.

1.2 Delivery of Certificate and New
Warrant. In the event of any exercise of the rights represented by this
Warrant, a certificate or certificates for the shares of Common Stock so
purchased, registered in the name of the Holder, together with any other
securities or other property which the Holder is entitled to receive upon
exercise of this Warrant, shall be delivered to the Holder hereof, at the
Company’s expense, within a reasonable time, not exceeding fifteen (15) calendar
days, after the rights represented by this Warrant shall have been so exercised;
and, unless this Warrant has expired, a new Warrant representing the number of
Shares (except a remaining fractional share), if any, with respect to which this
Warrant shall not then have been exercised shall also be issued to the Holder
hereof within such time. The person in whose name any certificate for shares of
Common Stock is issued upon exercise of this Warrant shall for all purposes be
deemed to have become the holder of record of such shares on the date on which
the Warrant was surrendered and payment of the Exercise Price was received by
the Company, irrespective of the date of delivery of such certificate.

1.3 Restrictive Legend. This Warrant and
the Shares have not been registered under the Securities Act of 1933, as

registration requirements of the Securities Act. Neither this Warrant nor any of
the Shares or any other security issued or issuable upon exercise of this
Warrant may be sold, transferred, pledged or hypothecated in the absence of an
effective registration statement under the Act relating to such security or an
exemption from the registration requirements of the Securities Act. Each
certificate for the Warrant, the Shares and any other security issued or
issuable upon exercise of this Warrant shall contain a legend on the face
thereof, in form and substance satisfactory to counsel for the Company, setting
forth the restrictions on transfer contained in this Section. The Holder
understands that this Warrant constitutes and the Shares upon issuance will
constitute “restricted securities” under the Securities Act. The holder
acknowledges and agrees that all certificates representing the Shares will be
endorsed with the following legend: 

“THE SECURITIES REPRESENTED BY THIS
CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE
"ACT"), AND HAVE BEEN ISSUED IN RELIANCE UPON AN EXEMPTION FROM THE REGISTRATION

SALE OR RESOLD OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH THE PROVISIONS
OF REGULATION S, PURSUANT TO AN EFFECTIVE REGISTRATION UNDER THE ACT, OR
PURSUANT TO AN AVAILABLE EXEMPTION FROM REGISTRATION UNDER THE ACT. HEDGING
TRANSACTIONS INVOLVING THE SECURITIES MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE
WITH THE ACT.” 

1.4 Fractional Shares. No fractional
Shares shall be issuable upon exercise or conversion of the Warrant and the
number of Shares to be issued shall be rounded down to the nearest whole Share.
If a fractional share interest arises upon any exercise or conversion of the
Warrant, the Company shall eliminate such fractional share interest by paying to
Holder an amount computed by multiplying the fractional interest by the current
market price of a full Share. 

1.5 Vesting. Warrants to purchase 210,000
common shares will be vested and immediately exercisable upon execution of this
Warrant Certificate by the Company. Warrants to purchase the balance of 90,000

satisfied the performance criteria set forth in Section 5.1(d) of the Consultant
Agreement.

1.6 Termination. Notwithstanding anything
else in the Warrant Certificate, this Warrant shall terminate and will cease to
be exercisable upon the earlier of (i) the Expiry Date, and (ii) the date that
is one year from the date of the termination of the Consultant Agreement for any
reason.

	2. 	Covenants of the Company.
  

2.1 Authorized Shares. The Company covenants and agrees
that the Company will at all times have authorized and reserved, free from
preemptive rights, a sufficient number of shares of Common Stock to provide for
the exercise in full of the rights represented by this Warrant.

2.2 Issuance of Shares. The Company covenants and agrees
that all shares of Common Stock that may be issued upon the exercise of the
rights represented by this Warrant will, upon issuance, be validly issued, fully
paid and non-assessable, and free from all transfer taxes, liens and charges
with respect to the issue thereof.

	3. 	Transfer and Replacement.
    

     (a) Subject to compliance with
any applicable securities laws and the conditions set forth herein, this Warrant
and all rights hereunder are transferable, in whole or in part, upon surrender
of this Warrant at the principal office of the Company, together with a written
assignment of this Warrant substantially in the form attached hereto duly
executed by the Holder or its agent or attorney and funds sufficient to pay any
transfer taxes payable upon the making of such transfer. Upon such surrender
and, if required, such payment, the Company shall execute and deliver a new
Warrant or Warrants in the name of the assignee or assignees and in the
denomination or denominations specified in such instrument of assignment, and
shall issue to the assignor a new Warrant evidencing the portion of this Warrant
not so assigned, and this Warrant shall promptly be cancelled. A Warrant, if
properly assigned, may be exercised by a new holder for the purchase of Shares
without having a new Warrant issued.

     (b) The Company agrees to
maintain, at its aforesaid office, books for the registration and the
registration of transfer of the Warrants. 

     (c) If, at the time of the
surrender of this Warrant in connection with any transfer of this Warrant, the
transfer of this Warrant shall not be registered pursuant to an effective
registration statement 

- 4 - 

under the Securities Act and under applicable state securities
or blue sky laws, the Company may require, as a condition of allowing such
transfer that (i) the Holder or transferee of this Warrant, as the case may be,
furnish to the Company a written opinion of counsel (which opinion shall be in
form, substance and scope customary for opinions of counsel in comparable
transactions) to the effect that such transfer may be made without registration
under the Securities Act and under applicable state securities or blue sky laws,
and (ii) that the holder or transferee execute and deliver to the Company such
documentation as is necessary to establish that the shares are being transferred
pursuant to an exemption from the registration requirements of the Securities
Act and applicable state securities laws or in an offshore transaction pursuant
to and in accordance with Rule 904 of Regulation S of the Securities Act. 

(d) The Company covenants that upon receipt by the Company of
evidence reasonably satisfactory to it of the loss, theft, destruction or
mutilation of this Warrant or any stock certificate relating to the Shares, and
in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it (which, in the case of the Warrant, shall not include the
posting of any bond), and upon surrender and cancellation of such Warrant or
stock certificate, if mutilated, the Company will make and deliver a new Warrant
or stock certificate of like tenor and dated as of such cancellation, in lieu of
such Warrant or stock certificate. 

	4. 	Adjustments of Exercise Price and/or
      Number of Shares. 

4.1 Subdivision or Combination of Shares.
The number and kind of securities purchasable upon the exercise of this Warrant
and the Exercise Price shall be subject to adjustment from time to time upon the
happening of any of the following. In case the Company shall (i) pay a dividend
in shares of Common Stock or make a distribution in shares of Common Stock to
holders of its outstanding Common Stock, (ii) subdivide its outstanding shares
of Common Stock into a greater number of shares, (iii) combine its outstanding
shares of Common Stock into a smaller number of shares of Common Stock, or (iv)
issue any shares of its capital stock in a reclassification of the Common Stock,
then the number of Shares purchasable upon exercise of this Warrant immediately
prior thereto shall be adjusted so that the Holder shall be entitled to receive
the kind and number of Shares or other securities of the Company which it would
have owned or have been entitled to receive had such Warrant been exercised in
advance thereof. Upon each such adjustment of the kind and number of Shares or
other securities of the Company which are purchasable hereunder, the Holder
shall thereafter be entitled to purchase the number of Shares or other
securities resulting from such adjustment at an Exercise Price per Warrant Share
or other security obtained by multiplying the Exercise Price in effect
immediately prior to such adjustment by the number of Shares purchasable
pursuant hereto immediately prior to such adjustment and dividing by the number
of Shares or other securities of the Company resulting from such adjustment. An
adjustment made pursuant to this paragraph shall become effective immediately
after the effective date of such event retroactive to the record date, if any,
for such event. 

4.2 Reorganization, Reclassification,
Consolidation, Merger or Sale. If any recapitalization,
reclassification or reorganization of the share capital of the Company, or any
consolidation or merger of the Company with another Company, or the sale of all
or substantially all of its shares and/or assets or other transaction
(including, without limitation, a sale of substantially all of its assets
followed by a liquidation) shall be effected in such a way that holders of
Common Stock shall be entitled to receive shares, securities or other assets or
property, then, as a condition of such recapitalizations, reclassifications,
reorganizations, consolidations, mergers or sales, lawful and adequate
provisions shall be made by the Company whereby the Holder hereof shall
thereafter have the right to purchase and receive (in lieu of the Common Stock
of the Company immediately theretofore purchasable and receivable upon the
exercise of the rights represented hereby) such shares, securities or other
assets or property as may be issued or payable with respect to or in exchange
for the number of outstanding Common Stock which such Holder would have been
entitled to receive had such Holder exercised this Warrant immediately prior to
the consummation of such recapitalizations, reclassifications, reorganizations,
consolidations, mergers or sales. The Company or its successor shall promptly
issue to 

- 5 - 

Holder a new Warrant for such new securities or other property.
The new Warrant shall provide for adjustments which shall be as nearly
equivalent as may be practicable to give effect to the adjustments provided for
in this Section 4 including, without limitation, adjustments to the Exercise
Price and to the number of securities or property issuable upon exercise of the
new Warrant. The provisions of this Section 4.2 shall similarly apply to
successive recapitalizations, reclassifications, reorganizations,
consolidations, mergers or sales.

4.3 Notice of Adjustment. Whenever
the number of Shares or number or kind of securities or other property
purchasable upon the exercise of this Warrant or the Exercise Price is adjusted,
as herein provided, the Company shall give notice thereof to the Holder, which
notice shall state the number of Shares (and other securities or property)
purchasable upon the exercise of this Warrant and the Exercise Price of such
Shares (and other securities or property) after such adjustment, setting forth a
brief statement of the facts requiring such adjustment and setting forth the
computation by which such adjustment was made. 

	5. 	Miscellaneous Provisions.

5.2 Limitation of Liability. No provision
hereof, in the absence of affirmative action by the Holder to purchase shares of
Common Stock, and no mere enumeration herein of the rights or privileges of the
Holder, shall give rise to any liability of the Holder for the Exercise Price
hereunder or as a stockholder of the Company, whether such liability is asserted
by the Company or by creditors of the Company.

shall not entitle the Holder to any of the rights of a stockholder of the

and shall not affect the meaning or construction of any of the provisions
hereof.

5.5 Warrant Certificate Personal to
Holder. This Warrant Certificate is issued to the Holder pursuant to the
Consultant Agreement and is personal to the Holder and may not be assigned
without the prior written consent of the Company.

      of Party B.  Prior to the distribution of the Escrowed
      Shares, if any, each of the Parties hereto agree that Party B shall have
      authority to settle all claims under this Agreement or the Purchase Agreement
      on
      behalf of any Seller Interest Holder who is entitled to receive a part of the
      Escrowed Shares, if any, upon the release and distribution from this
      escrow.  If after the Closing and prior to the distribution of the
      Escrowed Shares, Party B transfers record ownership of or assigns the Escrowed
      Shares to any Seller Interest Holder listed on Annex I hereto, each of the
      parties hereto agree that Mark Johnston shall have authority to settle all
      claims under this Escrow Agreement or the Purchase Agreement on behalf of the
      Seller Interest Holders who are entitled to receive a part of the Escrowed
      Shares upon the release and distribution from this escrow.  Unless
      context otherwise requires, any references to Party B contained herein shall
      be
      deemed to be references to Seller and to the Seller Interest Holders to the
      extent Escrowed Shares have been transferred or assigned to the Seller Interest
      Holders.

    5.           Deposit
      of Escrowed Shares.

     

    (a)           Promptly
      following the date of this Escrow Agreement, Party A and Party B shall instruct
      Continental Stock Transfer & Trust Company
      (“Continental”) to deliver the Escrowed Shares and
      stock powers signature guaranteed received by Continental in connection with
      the
      Escrowed Shares to the Escrow Agent.  The Escrowed Shares shall
      constitute an escrow fund (the “Escrow Fund”) for the
      satisfaction of Indemnification Claims of the Parent Indemnified Persons under
      the Purchase Agreement.  The Escrow Fund shall be held as a escrow
      fund and shall not be subject to any lien, attachment, trustee process or any
      other judicial process of any creditor of any person, including any Party
      hereto.  The Escrow Agent agrees to accept delivery of the Escrowed
      Shares and stock powers and to hold the Escrowed Shares and stock powers in
      an
      escrow account, subject to the terms and conditions of this Escrow
      Agreement.

    

    (b)           Each
      record owner of the Escrowed Shares shall be entitled to exercise all voting
      rights with respect to such owner’s Escrowed Shares.

    

    (c)           Party
      A and Party B agree between themselves, for the benefit of Party A and the
      Escrow Agent, that any securities or other property distributable (whether
      by
      way of dividend, stock split or otherwise) in respect of or in exchange for
      any
      Escrowed Shares shall not be distributed to the record owners of such Escrowed
      Shares, but rather shall be distributed to and held by the Escrow Agent in
      the
      Escrow Fund.  Ordinary cash dividends will be paid by Party A directly
      to the Seller Interest Holders or other record owners of such Escrowed Shares
      and not to the Escrow Agent.  Unless and until the Escrow Agent shall
      actually receive such additional securities or other property, it may assume
      without inquiry that the Escrowed Shares currently being held by it in the
      Escrow Fund are all that the Escrow Agent is required to hold.  At the
      time any Escrowed Shares are required to be released from the Escrow Fund to
      any
      Person pursuant to this Agreement, any securities or other property previously
      received by the Escrow Agent in respect of or in exchange for such Escrowed
      Shares shall be released from the Escrow Fund to such Person.

    

    6.           Release
      Date.  For purposes of this Agreement, the
“Release Date” shall be June 26, 2008.

    

    7.           Administration
      of Escrow Fund.  Except as otherwise provided herein, the
      Escrow Agent shall administer the Escrow Fund as follows:

    

    (a)           If,
      as of the Release Date, the Escrow Agent has not received written notice of
      any
      Indemnification Claims, then the Escrowed Shares, less the amount of all Claimed
      Amounts that have not been paid or otherwise resolved as of the Release Date
      (the “Retained Amount”) shall promptly (and in any
      event no later than ten Business Days thereafter) be released to Seller or
      to
      the Seller Interest Holders in whose names they have been issued as detailed
      in
      a joint written notice from Party A and Party B detailing the delivery
      instructions.  Upon resolution of all Claim Notices made prior to the
      Release Date, that portion of the Retained Amount that is not paid to Party
      A in
      satisfaction of such Claims Notice shall immediately be disbursed to Seller
      or
      to the Seller Interest Holders as set forth in the joint delivery instructions
      delivered as of the Release Date.

    

    (b)           Subject
      to the terms and conditions set forth in Section 9.04 of the Purchase Agreement,
      if Party A desires to make a claim against the Escrow Fund with respect to
      any
      Indemnification Claim, then Party A shall, on or prior 5:00 p.m. Central Time
      on
      June 25, 2008, deliver a written claim notice (a “Claim
      Notice”) to Party B and to the Escrow Agent.  Such Claim
      Notice shall (i) state that Party A believes in good faith that it is entitled
      to all or any portion of the Escrow Fund and certify that all requirements
      set
      forth in Article IX of the Purchase Agreement with respect to such
      indemnification have been satisfied; (ii) contain a reasonably detailed
      description of the circumstances supporting such belief; and (iii) indicate
      the
      good faith claimed amount of Damages necessary to satisfy such indemnification
      claim (the “Claimed Amount”) and what portion of the
      Escrow Funds are expected in good faith to be necessary to satisfy such
      Indemnification Claim.  The number of Escrowed Shares, if any, to be
      released shall be determined in accordance with Section7(d)
      below.

    

    (c)           Prior
      to 5:00 p.m. Central Time on the (30th) thirtieth day after receipt by Escrow
      Agent of a Claim Notice, Party B may deliver to Party A and to the Escrow Agent
      a written response (the “Response Notice”) in which
      Party B may:  (i) agree that the full Claimed Amount may be released
      from the Escrow Fund to

    

    
      
        
          
          

        

        
          2

          
            

          

        

        
          
          

        

      

    

    

    Party
      A;
      (ii) agree that part, but not all, of the Claimed Amount (the
“Agreed Amount”) may be released from the Escrow Fund
      to Party A; or (iii) indicate that no part of the Claimed Amount may be released
      from the Escrow Fund to Party A.  Any part of the Claimed Amount that
      is not to be released to Party A shall be the “Contested
      Amount.”

    

    (A)           If
      Party B does not deliver a Response Notice within such 30-day period, then
      Party
      B shall be deemed to have indicated that the entire Claimed Amount may be
      released from Escrow Fund to Party A.

    

    (B)           If
      Party B delivers a Response Notice agreeing that the full Claimed Amount may
      be
      released from the Escrow Fund to Party A, the Escrow Agent shall promptly
      following the receipt of the Response Notice, deliver to Party A such number
      of
      Escrowed Shares, if any, equal in the aggregate to the Claimed
      Amount.

    

    (C)           If
      Party B delivers a Response Notice agreeing that part, but not all, of the
      Claimed Amount may be released from the Escrow Fund to Party A, the Escrow
      Agent
      shall promptly following the receipt of the Response Notice deliver to Party
      A
      such number of Escrowed Shares, if any, equal in the aggregate to the Agreed
      Amount.

    

    (D)           If
      Party B delivers a Response Notice indicating that there is a Contested Amount,
      Party B and Party A shall attempt in good faith to resolve the dispute related
      to the Contested Amount.  If Party A and Party B shall resolve such
      dispute, such resolution shall be binding on Party B and Party A and any other
      Buyer Indemnitee and Seller Indemnitee, as applicable, and a settlement
      agreement shall be signed by Party A and Party B and sent to the Escrow Agent,
      who shall, upon receipt thereof, if applicable, release Escrowed Shares, if
      any,
      from the Escrow Fund in accordance with the specific instructions provided
      in
      such agreement.

    

    (E)           If
      Party B and Party A are unable to resolve the dispute relating to any Contested
      Amount within 45 days after the delivery of the Claim Notice, the settlement
      of
      such Contested Amount shall take place by a binding arbitration proceeding
      which
      shall take place in Austin, Texas, unless an alternative location is otherwise
      mutually agreed to by Party A and Party B, and be conducted by an arbitrator
      who
      has not been affiliated with or engaged by either party for a period of five
      years preceding the commencement of the arbitration proceeding, and the Escrow
      Agent shall continue to hold the Contested Amount until Escrow Agent receives
      either:  (i) a written notice signed by Party A and Party B, providing
      specific written instructions regarding the delivery of the Contested Amount,
      if
      any, to be released from the Escrow Fund; or (ii) a final arbitration decision,
      in accordance with the following procedures, providing specific written
      instructions regarding the delivery of any or all of such Contested
      Amount.  The Contested Amount shall be settled in accordance with the
      Expedited Procedures of the Commercial Arbitration Rules of the American
      Arbitration Association.  The arbitrator's decision shall relate
      solely to whether Party A is entitled to receive the Contested Amount (or a
      portion thereof) from the Escrow Fund pursuant to the applicable terms of the
      Purchase Agreement and this Escrow Agreement.  The final decision of
      the arbitrator shall be furnished to Party A, Party B and the Escrow Agent
      in
      writing and shall constitute the conclusive determination of the issue in
      question, be binding upon Party A, the Seller Interest Holders and the Escrow
      Agent.  The prevailing party in any arbitration (which determination
      shall be made by the arbitrator) shall be entitled to an award of attorneys’
fees and costs to be paid by the losing party (which determination shall be
      made
      by the arbitrator), and the losing party shall also be liable for all costs
      of
      arbitration, including, but not limited to, the compensation to be paid to
      the
      arbitrator in any proceeding and the transcript and other expenses of such
      proceeding.

    

    (d)           In
      the event Seller has transferred record ownership of the Escrowed Shares to
      the
      Seller Interest Holders, any amounts distributed to Party A from the Escrow
      Fund
      shall be satisfied pro rata from each Seller Interest Holder’s Escrowed Shares
      in accordance with each Seller Interest Holder’s Percentage Interest set forth
      on Annex I to this Escrow Agreement.

    

    (e)           The
      number of Escrowed Shares, if any, to be released in payment and settlement
      of
      any Claimed Amount, Agreed Amount or all or any portion of the Contested Amount
      which may be awarded to Party A pursuant to Section 7(c)(E) above shall
      be determined by dividing such Claimed Amount, Agreed Amount or award, as
      applicable, by the average closing sale price per share of Buyer Common Stock
      as
      reported on the Nasdaq Global Select Market for the 30 consecutive trading
      days
      ending on the date that is one (1) trading day immediately

    

    
      
        
          
          

        

        
          3

          
            

          

        

        
          
          

        

      

    

    

    preceding
      the release of such shares (as adjusted as appropriate to reflect any stock
      splits, stock dividends, combinations, reorganizations, reclassifications or
      similar events).  The Escrow Agent will not be responsible for
      determining the share price.

    

    8.           Escrow
      Agent.  The Escrow Agent undertakes to perform only such
      duties as are expressly set forth herein and no duties shall be implied. The
      Escrow Agent shall have no liability under and no duty to inquire as to the
      provisions of any agreement other than this Escrow Agreement.  The
      Escrow Agent may rely upon any written notice, document, instruction or request
      furnished to it hereunder and believed by it to be genuine and to have been
      signed or presented by the proper party or parties.  The Escrow Agent
      shall be under no duty to inquire into or investigate the validity, accuracy
      or
      content of any such document, notice, instruction or request.  The
      Escrow Agent shall have no duty to solicit any payments which may be due it
      or
      the Escrow Fund.  The Escrow Agent shall not be liable for any action
      taken or omitted by it in good faith except to the extent that a final
      adjudication of a court of competent jurisdiction determines that the
      Escrow Agent's gross negligence or willful misconduct was the primary cause
      of
      any loss to either of the Parties.  The Escrow Agent may execute any
      of its powers and perform any of its duties hereunder directly or through agents
      or attorneys (and shall be liable only for the careful selection of any such
      agent or attorney) and may consult with counsel, accountants and other skilled
      persons to be selected and retained by it.  The Escrow Agent shall not
      be liable for anything done, suffered or omitted in good faith by it in
      accordance with the advice or opinion of any such counsel, accountants or other
      skilled persons except to the extent that a final adjudication of a court
      of competent jurisdiction determines that the Escrow Agent's gross negligence
      or
      willful misconduct was the primary cause of any loss to either of the
      Parties.  In the event that the Escrow Agent shall be uncertain as to
      its duties or rights hereunder or shall receive instructions, claims or demands
      from any party hereto which, in its opinion, conflict with any of the provisions
      of this Escrow Agreement, it shall be entitled to refrain from taking any action
      and its sole obligation shall be to keep safely all property held in escrow
      until it shall be directed otherwise in writing by all of the other parties
      hereto or by a final order or judgment of a court of competent
      jurisdiction.  The Escrow Agent may interplead all of the assets held
      hereunder into a court of competent jurisdiction or may seek a declaratory
      judgment with respect to certain circumstances, and thereafter be fully relieved
      from any and all liability or obligation with respect to such interpleaded
      assets or any action or nonaction based on such declaratory
      judgment.  The parties hereto other than the Escrow Agent agree to
      pursue any redress or recourse in connection with any dispute without making
      the
      Escrow Agent a party to the same.  Anything in this Escrow Agreement
      to the contrary notwithstanding, in no event shall the Escrow Agent be liable
      for special, indirect or consequential loss or damage of any kind whatsoever
      (including but not limited to lost profits), even if the Escrow Agent has been
      advised of the likelihood of such loss or damage and regardless of the form
      of
      action. Escrow
      Agent
      may rely on the validity, accuracy and content of the statements contained
      any
      written notice, document, instruction, or request furnished to it hereunder
      by
      Party A and Party B without further investigation, inquiry or
      examination.  For the avoidance of doubt, the Escrow Agent shall have
      no liability with respect to any provisions of this Escrow Agreement which
      set
      forth obligations or limitations of liability that the other parties to this
      Esrcrow Agreement have to each other.  The Escrow Agent shall have no
      obligation to investigate, inquire, examine or assist in any manner whatsoever,
      the parties' compliance with the terms of this Escrow Agreement that incorporate
      by reference provisions of the Purchase Agreement that apply to the other
      parties' obligations or limitations of liability to each other that do not
      relate to obligations of the Escrow Agent under this Escrow
      Agreement.

    

    9.           Succession.  The
      Escrow Agent may resign and be discharged from its duties or obligations
      hereunder by giving its written resignation to the Parties.  Such
      resignation shall take effect on the earlier of (a) a successor escrow agent
      being in place and (b) thirty days after such resignation is given to the
      Parties.  In such event, Party A may appoint a successor escrow
      agent.  If Party A fails to appoint a successor escrow agent within
      fifteen days after receiving the Escrow Agent’s written resignation, the Escrow
      Agent shall have the right to apply to a court of competent jurisdiction for
      the
      appointment of a successor escrow agent.  The successor escrow agent
      shall execute and deliver to the Escrow Agent an instrument accepting such
      appointment and the successor escrow agent shall, without further acts, be
      vested with all the estates, property rights, powers and duties of the
      predecessor Escrow Agent as if originally names as Escrow Agent
      herein.  The Escrow Agent shall act in accordance with written
      instructions from Party A and Party B as to the transfer of the Escrow Fund
      to a
      successor escrow agent.  If the Parties have failed to appoint a
      successor escrow agent prior to the expiration of thirty days following receipt
      of the notice of resignation, the Escrow Agent may petition any court of
      competent jurisdiction for the appointment of

    

    
      
        
          
          

        

        
          4

          
            

          

        

        
          
          

        

      

    

    

    a
      successor escrow agent or for other appropriate relief, and any such resulting
      appointment shall be binding upon all of the parties hereto.

    

    10.           Removal
      of Escrow Agent.  The Escrow Agent may be removed at any
      time by mutual agreement of Party A and Party B by giving not less than 30
      days’
prior written notice to the Escrow Agent.  Prior to the expiration of
      such 30-day period, Party A and Party B shall designate, by mutual consent,
      a
      successor escrow agent.  If no successor escrow agent is appointed
      within such 30-day period, the Escrow Agent may deposit the amounts remaining
      in
      the Escrow Fund with a court of competent jurisdiction located in Austin, Texas,
      whereupon the Escrow Agent shall be discharged of all duties and obligations
      hereunder.

    

    11.           Compensation
      and Reimbursement.  Party
      A agrees to (a) pay the Escrow Agent upon execution of this Escrow Agreement
      and
      from time to time thereafter reasonable compensation for the services to be
      rendered hereunder, which unless otherwise agreed in writing shall be as
      described in Annex III attached hereto, and (b) pay or reimburse the Escrow
      Agent upon request for all expenses, disbursements and advances, including
      reasonable attorney's fees and expenses, incurred or made by it in connection
      with the preparation, execution, performance, delivery, modification and
      termination of this Escrow Agreement.

    

    12.           Indemnity.  The
      Parties shall jointly and severally indemnify, defend and save harmless the
      Escrow Agent and its directors, officers, agents and employees (the
“indemnitees”) from and against any and all loss,
      liability or expense (including the fees and expenses of in house or outside
      counsel and experts and their staffs and all expense of document location,
      duplication and shipment) arising out of or in connection with (a) the Escrow
      Agent's execution and performance of this Escrow Agreement, except in the case
      of any indemnitee to the extent that such loss, liability or expense is finally
      adjudicated to have been primarily caused by the gross negligence or willful
      misconduct of such indemnitee, or (b) its following any instructions or other
      directions from Party A or Party B, except to the extent that its following
      any
      such instruction or direction is expressly forbidden by the terms
      hereof.  The Parties hereto acknowledge that the foregoing indemnities
      shall survive the resignation or removal of the Escrow Agent or the termination
      of this Escrow Agreement.  The Parties hereby grant the Escrow Agent a
      lien on, right of set-off against and security interest in the Escrow Fund
      for
      the payment of any claim for indemnification, compensation, expenses and amounts
      due hereunder.

    

    13.           Account
      Opening Information/TINs.

    

    IMPORTANT
      INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT

    

    For
      accounts opened in the US:

    To
      help
      the government fight the funding of terrorism and money laundering activities,
      Federal law requires all financial institutions to obtain, verify, and record
      information that identifies each person who opens an account.  When an
      account is opened,  the Escrow Agent will ask for information that
      will allow us to identify relevant parties.

    

    For
      non-US accounts:

    To
      help
      in the fight against the funding of terrorism and money laundering activities
      we
      are required along with all financial institutions to obtain, verify, and record
      information that identifies each person who opens an account. When you open
      an
      account, the Escrow Agent will ask for information that will allow us to
      identify you.

    

    TINs.Tax
      Matters. The Parties each represent that its correct Taxpayer
      Identification Number (“TIN”) assigned by the Internal
      Revenue Service (“IRS”) or any other taxing authority
      is set forth on the signature page hereof.  In
      addition, all interest or other income earned under the Escrow Agreement shall
      be reported by the recipient to the Internal Revenue Service or any other taxing
      authority.  Notwithstanding such written directions, Escrow Agent
      shall report and, as required, withhold any taxes as it determines may be
      required by any law or regulation in effect at the time of the
      distribution.  In the event that any earnings remain undistributed at
      the end of any calendar year, Escrow Agent shall report to the Internal Revenue
      Service or such other authority such earnings as it deems appropriate or as
      required by any applicable law or regulation or, to the extent consistent
      therewith, as directed in writing by the Parties.  In the absence of
      such written directions, undistributed earnings will be reported on
      as

    

    
      
        
          
          

        

        
          5

          
            

          

        

        
          
          

        

      

    

    

    belonging
      to Party A, and Party A shall be treated for federal income tax purposes as
      the
      owner of the property subject to the Escrow Agreement.

    

    14.           Notices.

      law
      or executive order to remain closed.

    

    15.           Security
      Procedures.  In the event funds transfer
      instructions are given (other than in writing at the time of execution of this
      Escrow Agreement, as indicated in Section 9 above), whether in writing,
      by telecopier or otherwise, the Escrow Agent is authorized to seek confirmation
      of such instructions by telephone call-back to the person or persons designated
      on Annex III hereto, and the Escrow Agent may rely upon the confirmation of
      anyone purporting to be the person or persons so designated.  The
      persons and telephone numbers for call-backs may be changed only in a writing
      actually received and acknowledged by the Escrow Agent. If the Escrow Agent
      is
      unable to contact any of the authorized representatives identified in Annex
      III,
      the Escrow Agent is hereby authorized to seek confirmation of such instructions
      by telephone call-back to any one or more of your executive officers,
      (“Executive Officers”), which shall include the titles
      of President or Chief Financial Officer as the Escrow Agent may
      select.  Such Executive Officer shall deliver to the Escrow Agent a
      fully executed Incumbency Certificate, and the Escrow Agent may rely upon the
      confirmation of anyone purporting to be any such officer. The Escrow Agent
      and
      the beneficiary's bank in any funds transfer may rely solely upon any account
      numbers or similar identifying numbers provided by Party A or Party B to
      identify (a) the beneficiary, (b) the beneficiary's bank, or (c) an intermediary
      bank.  The Escrow Agent may apply any of the escrowed funds for any
      payment order it executes using any such identifying number, even when its
      use
      may result in a person other than the beneficiary being paid, or the transfer
      of
      funds to a bank other than the beneficiary's bank or an intermediary bank
      designated. The parties to this Escrow Agreement acknowledge that these security
      procedures are commercially reasonable.  Party A and Party B agree
      that repetitive or standing settlement instructions will be effective as the
      funds transfer instructions of Party A and Party B, whether or not authorized,
      if such settlement instructions are verified pursuant to the security procedure
      provided herein or such other security procedure that the Escrow Agent, Party
      A
      and Party B may agree to.

    

    16.           Miscellaneous.  The
      provisions of this Escrow Agreement may be waived, altered, amended or
      supplemented, in whole or in part, only by a writing signed by all of the
      parties hereto.  Neither this Escrow Agreement nor any right or
      interest hereunder may be assigned in whole or in part by any party, except
      as
      provided in Sections 9 and 10, without the prior consent of the
      other parties.  This Escrow Agreement shall be binding upon each of
      the parties hereto and each of their respective successors and assigns, if
      any.  Nothing in this Escrow Agreement is intended to confer, or shall
      be deemed to confer, any rights or remedies upon any person or entity other
      than
      the parties hereto and their successors and assigns.  This Escrow
      Agreement shall inure to the benefit of: Party A, the Seller Interest Holders,
      Party B, Escrow Agent and their respective successors and assigns, if any,
      of
      the foregoing.  This Escrow Agreement shall be governed by and
      construed under the laws of the State of Texas.  Each party hereto
      irrevocably waives any objection on the grounds of venue, forum non-conveniens
      or any similar grounds and irrevocably consents to service of process by mail
      or
      in any other manner permitted by applicable law and consents to the jurisdiction
      of the courts located in the State of Texas.  The parties further
      hereby waive any right to a trial by jury with respect to any lawsuit or
      judicial proceeding arising or relating to this Escrow Agreement.  No
      party to this Escrow Agreement is liable to any other party for losses due
      to,
      or if it is unable to perform its obligations under the terms of this Escrow
      Agreement because of, acts of God, fire, war, terrorism, floods, strikes,
      electrical outages, equipment or transmission failure, or other causes
      reasonably beyond its control.  This Escrow Agreement and the other
      agreements referred to herein set forth the entire understanding of the parties
      hereto relating to the subject matter hereof and thereof and supersede all
      prior
      agreements and understandings among or between any of the parties relating
      to
      the subject matter hereof and thereof.  Nothing in this Escrow
      Agreement shall derogate from, or modify in any respect any of the terms and
      provisions of the Purchase Agreement, including Article IX thereof, with respect
      to indemnification.  In the event any provision of this Escrow
      Agreement shall be held invalid or unenforceable by any court of competent
      jurisdiction, such holding shall not invalidate or render unenforceable any
      other provision of this Escrow Agreement and each and every other provision
      of
      this Escrow Agreement shall continue in full force and effect.  The
      waiver by any party hereto of a breach of any provision of this Escrow Agreement
      shall not operate or be construed as a waiver of any other or subsequent breach
      by any party.  This Escrow Agreement may be executed in one or more
      counterparts, each of which shall be deemed an original, but all of which
      together shall constitute one and the same instrument. All signatures of the
      parties to this
      Escrow Agreement may be transmitted by facsimile, and such facsimile will,
      for
      all purposes, be deemed to be the original signature of such party whose
      signature it reproduces, and will be binding upon such
      party.

      Escrow Agreement shall terminate upon the earliest occurrence of any of the
      following events: (a) the written agreement of Party A and Party B; or
      (b) upon the delivery by Escrow Agent of all of the Escrow Fund in
      accordance with the terms of this Agreement; provided, however, that Sections
      7(c) and 11 shall survive any termination of this
      Agreement.

    

    18.           Compliance
      with Court Orders.  In the event that
      any escrow property shall be attached, garnished or levied upon by any court
      order, or the delivery thereof shall be stayed or enjoined by an order of a
      court, or any order, judgment or decree shall be made or entered by any court
