        Survival.
        The
        representations, warranties, covenants, and obligations in this Agreement,
        and
        any certificate or document delivered pursuant to this Agreement, shall
        terminate at the Closing or upon termination of this Agreement pursuant to
        Section 10.01 and shall not survive the Closing except that the provisions
        of
        Sections 6.01, 6.03 and 9.02 of this Agreement shall survive the Closing.
        Stockholder will not have any liability under this Agreement resulting from
        any
        event relating to a Breach of any representation, warranty, convenant or
        agreement made in this Agreement. 

       

      9.02  Indemnification
        of Directors and Officers.

       

      (a) From
        and
        after the Effective Time, the Company shall, and Purchaser shall cause the
        Company to, indemnify and hold harmless each present and former director
        and/or
        officer of the Company (the “Indemnified Parties”), that is made a party or
        threatened to be made a party to any threatened, pending or completed, action,
        suit, proceeding or claim, whether civil, criminal, administrative or
        investigative, by reason of the fact that he or she was a director or officer
        of
        the Company prior to the Closing Date and arising out of actions or omissions
        of
        the Indemnified Party in any such capacity occurring at or prior to the Closing
        Date (a “Claim”) against any costs or expenses (including reasonable attorneys’
        fees), judgments, fines, amounts paid in settlement pursuant to Section 9.02(b),
        losses, claims, damages or liabilities (collectively, “Costs”) reasonably
        incurred in connection with any Claim, whether asserted or claimed prior
        to, at
        or after the Closing Date, to the fullest extent that the Company would have
        been permitted under applicable law and the Company’s Certificate of
        Incorporation, as amended, and By-laws, as amended, in effect as of the Closing
        Date. The Company shall, and Purchaser shall cause the Company to, advance
        expenses (including reasonable attorneys’ fees), as reasonably incurred by the
        Indemnified Party to the fullest extent permitted under applicable law provided
        such Indemnified Party provides an undertaking to repay such advances if
        it is
        ultimately determined that such Indemnified Party is not entitled to
        indemnification. 

       

      (b) Any
        Indemnified Party wishing to claim indemnification under paragraph (a) of
        this
        Section 9.02 upon learning of any such Claim, shall promptly notify Purchaser
        and the Company thereof, but the failure to so notify shall not relieve
        Purchaser and the Company of any liability they may have to such Indemnified
        Party if such failure does not materially prejudice Purchaser and the Company.
        In the event of any such claim, action, suit, proceeding or investigation
        (whether arising before or after the Effective Time), (i) Purchaser and the
        Company shall have the right to assume the defense thereof and Purchaser
        and the
        Company shall not be liable to such Indemnified Parties for any legal expenses
        of other counsel or any other expenses subsequently incurred by such Indemnified
        Parties in connection with the defense thereof, except that if Purchaser
        and the
        Company elect not to assume such defense or counsel or the Indemnified Parties
        advise and Purchaser’s and the Company’s counsel concurs that there are issues
        which raise conflicts of interest between Purchaser and the Company, on the
        one
        hand, and the Indemnified Parties, on the other, in either such case the
        Indemnified Parties may retain counsel satisfactory to them, and Purchaser
        and
        the Company shall pay all reasonable fees and expenses of such counsel for
        the
        Indemnified Parties promptly as statements therefor are received; provided,
        however,
        that
        Purchaser and the Company shall be obligated pursuant to this paragraph (b)
        to
        pay for only one firm or counsel for all Indemnified Parties in any jurisdiction
        unless the use of one counsel for such Indemnified Parties would present
        such
        counsel with a conflict of interest, (ii) the Indemnified Parties will cooperate
        in the defense of any such matter and (iii) Purchaser and the Company shall
        not
        be liable for any amounts paid in settlement effected without their prior
        written consent, which consent will not be unreasonably withheld; and
provided,
        further,
        however,
        that
        Purchaser and the Company shall not have any obligation hereunder to any
        Indemnified Party when and if a court of competent jurisdiction shall ultimately
        determine, and such determination shall have become final and non-appealable,
        that the indemnification of such Indemnified Party in a manner contemplated
        hereby is prohibited by applicable law. If such indemnity is not available
        with
        respect to any Indemnified Party, then Purchaser and the Company and the
        Indemnified Party shall contribute to the amount payable in such proportion
        as
        is appropriate to reflect relative faults and benefits.

      (c) If
        a
        Claim under this Section 9.02 is not paid in full by Purchaser and the Company
        within thirty days after a written request therefor has been received by
        Purchaser and the Company, the Indemnified Party may at any time thereafter
        bring suit against Purchaser and the Company to recover the unpaid amount
        of the
        Claim and, if successful in whole or in part, the Indemnified Party shall
        be
        entitled to be paid also the expense of prosecuting such Claims.

       

      (d) Neither
        the failure of Purchaser and the Company (including their respective Boards
        of
        Directors, independent legal counsel or stockholders) to have made a
        determination prior to the commencement of such suit that indemnification
        of the
        Indemnified Party is proper in the circumstances because he or she has met
        the
        applicable standard of conduct, nor an actual determination by Purchaser
        and the
        Company (including their respective Boards of Directors, independent legal
        counsel, or stockholders) that the Indemnified Party has not met such applicable
        standard of conduct, shall be a defense to the suit or create a presumption
        that
        the Indemnified Party has not met the applicable standard of
        conduct.

      10.01  Termination.
        This
        Agreement may, by notice given prior to or at the Closing, be
        terminated:

       

      (i)  by
        the
        mutual written agreement of Purchaser and Stockholder;

       

      (ii)  by
        either
        Purchaser or Stockholder if a material Breach of any provision of this Agreement
        has been committed by the other party and such Breach has not been waived
        or
        cured;

       

      (iii)  (a)
        by
        Purchaser if any of the conditions contained in Article
        VII
        has not
        been satisfied as of the Closing, or if satisfaction of such a condition
        is or becomes impossible (other than through the failure of Purchaser to comply with its
        obligations under this Agreement) and Purchaser has not waived such condition
        on or before October 31, 2005, or (b) by Stockholder if any of the conditions
        in Article VIII has not been satisfied as of October 31, 2005, or
        if satisfaction of such a condition is or becomes impossible (other than
        through the failure of Stockholder to comply with their obligations under this
        Agreement) and Stockholder has not waived such condition on or before October
        31, 2005.

      (iv)  if
        the
        Closing shall not have occurred (other than through the failure of any party
        seeking to terminate this Agreement to comply fully with its obligations
        under
        this Agreement) as of October 31, 2005, or such later date as the parties
        may
        agree upon in writing.

       

      (v)  by
        Stockholder in the event that, at any time prior to the Closing Date, the
        board
        of directors of either Stockholder or the Company determines in good faith,
        based on the advice of outside counsel, that failure to do so would be
        reasonably likely to constitute a breach of its fiduciary duties under
        applicable law.

      


      (b)  Nothing
        in this Section
        10.01
        shall
        relieve any party of any liability for a Breach of this Agreement prior to
        the

      (c)  Except
        as
        provided in Sections 6.01, 6.03, 9.01 and 9.02, in the event of termination
        of
        this Agreement pursuant to this Section 10.01, this Agreement shall forthwith
        become void, there shall be no liability under this Agreement on the part
        of
        Stockholder, the Company or Purchaser or any of their respective officers
        or
        directors and all rights and obligations of each party hereto shall
        cease.

       

      10.02  Expenses.
        The
        parties hereto shall pay all of their own expenses relating to the transactions

      10.03  Governing
        Law.
        The
        interpretation and construction of this Agreement, the Subject Transactions
        and
        all matters relating hereto, shall be governed by the laws of the State of
        Texas.

       

      10.04  Enforcement;
        Venue; Service of Process.
        In the
        event either party shall seek enforcement of any covenant, warranty or other
        term or provision of this Agreement or seeks to recover damages for the breach
        thereof, the party which prevails in such proceedings shall be entitled to
        recover reasonable attorneys’ fees and expenses actually incurred by it in
        connection therewith. Subject to Section
        10.13,
        and
        without waiving the same, the parties hereto agree that this Agreement is
        performable in Bexar County, Texas and that the sole and exclusive venue
        for any
        proceeding involving any claim arising under or relating to this Agreement
        shall

      10.13  Arbitration;
        Waiver of Trial By Jury.

       

      (a)  Any
        and
        every dispute of any nature whatsoever that may arise between the parties
        hereto, whether sounding in contract, statute, tort, fraud, misrepresentation,
        discrimination or any other legal theory, including, but not limited to,
        disputes relating to or involving the construction, performance or breach
        of
        this Agreement, or any schedule, certificate or other document delivered
        by any
        party hereto or thereto, or any other agreement between the parties hereto,
        whether entered into prior to, on, or subsequent to the date of this Agreement,
        or those arising under any federal, state or local law, regulation or ordinance,
        shall be determined by binding arbitration in accordance with the then current
        commercial arbitration rules of the American Arbitration Association, to
        the
        extent such rules do not conflict with the provisions of this paragraph.
        If the
        amount in controversy in the arbitration exceeds Two Hundred Fifty Thousand
        Dollars ($250,000), exclusive of interest, attorneys’
        fees and
        costs, the arbitration shall be conducted by a panel of three (3) neutral
        arbitrators. Otherwise, the arbitration shall be conducted by a single neutral
        arbitrator. The parties hereto shall endeavor to select neutral arbitrators
        by
        mutual agreement. If such agreement cannot be reached within thirty (30)
        calendar days after a dispute has arisen which is to be decided by arbitration,
        any party or the parties jointly shall request the American Arbitration
        Association to submit to each party an identical panel of fifteen (15) persons.
        Alternate strikes shall be made to the panel, commencing with the party bringing
        the claim, until the names of three (3) persons remain, or one (1) person
        if the
        case is to be heard by a single arbitrator. The parties may, however, by
        mutual
        agreement, request the American Arbitration Association to submit additional
        panels of possible arbitrators. The person(s) thus remaining shall be the
        arbitrator(s) for such arbitration. If three (3) arbitrators are selected,
        the
        arbitrators shall elect a chairperson to preside at all meetings and hearings.
        The arbitrator(s), or a majority of them, shall have the power to determine
        all
        matters incident to the conduct of the arbitration, including without limitation
        all procedural and evidentiary matters and the scheduling of any hearing.
        The
        award made by a majority of the arbitrators shall be final and binding upon
        the
        parties thereto and the subject matter. The arbitration shall be governed
        by the
        United States Arbitration Act, 9 U.S.C. §1-16, and judgment upon the award
        rendered by the arbitrator(s) may be entered by any court having jurisdiction
        thereof. The arbitrators shall have no authority to award punitive or exemplary
        damages or any statutory multiple damages, and shall only have the authority
        to
        award compensatory damages, arbitration costs, attorneys’ fees, declaratory
        relief and permanent injunctive relief, if applicable. Unless otherwise agreed
        by the parties, the arbitration shall be held in San Antonio, Texas. This
        Section
        10.13
        shall
        not prevent either party from seeking a temporary restraining order or temporary
