        shall be entitled to rely on advice of counsel concerning all matters
        pertaining to such duties, and protected in respect of any action taken
        in good faith and in accordance with such advice.

                 (b)     Neither the Disbursement Agent nor any of its
        officers, directors, employees, agents, attorneys-in-fact or affiliates
        shall be (i) liable for any action lawfully taken or omitted to be
        taken by it or such Person under or in connection with this Agreement
        (except for its or such Person's own gross negligence or willful
        misconduct) or (ii) responsible in any manner to TEC for any recitals,
        statements, representations or warranties made by TransTexas or any
        officer thereof contained in any certificate, report, statement or

        Disbursement Agent under or in connection with, this Agreement.  The
        Disbursement Agent shall not be under any obligation to TEC to inspect
        the properties, books or records of TransTexas.

                 (c)     The Disbursement Agent shall be entitled to rely, and
        shall be fully protected in relying, upon any note, writing,
        resolution, notice, consent, certificate, affidavit, letter, cablegram,
        telegram, telecopy, telex or teletype message, statement, order or

        or Persons and upon advice and statements of legal counsel (including,
        without limitation, counsel to TransTexas), independent accountants and
        other experts selected by the Disbursement Agent.  The Disbursement
        Agent shall be fully justified in failing or refusing to take any
        action hereunder if such action would, in the opinion of the
        Disbursement Agent, be contrary to law or the terms of this Agreement.

                 (d)     The Disbursement Agent shall not be deemed to have
        knowledge or notice of the occurrence of any Event of Default unless
        the Disbursement Agent has received written notice from TEC, TransTexas
        or the Trustee, describing such Event of Default and stating that such
        notice is a "notice of default."  The Disbursement Agent shall take
        such action with respect to such Event of Default as shall be required
        by this Agreement.  No provision of this Agreement shall require the
        Disbursement Agent to expend or risk its own funds or otherwise incur
        any financial liability in the performance of any of its duties
        hereunder or in the exercise of any of its rights or powers, if it
        shall have reasonable grounds for believing that repayment of such
        funds or adequate indemnity against such risk or liability is not
        reasonably assured to it.

        SECTION 2.3  Resignation and Removal of Disbursement Agent.

                 (a)     Subject to the appointment and acceptance of a
        successor Disbursement Agent as provided below, the Disbursement Agent

        TransTexas shall have the right to appoint a successor Disbursement
        Agent, which shall be a bank or trust company reasonably acceptable to
        TEC and the Trustee.  If no successor Disbursement Agent

        a successor Disbursement Agent to serve hereunder, which shall be a
        bank or trust company reasonably acceptable to the other party.

                 (c)     Upon the acceptance of any appointment as Disbursement
        Agent hereunder by a successor Disbursement Agent, (i) such successor

        agreement substantially identical to this Agreement, (ii) such
        agreement shall provide that such successor Disbursement Agent shall

        obligations hereunder and (iii) the retiring Disbursement Agent shall

        necessary to transfer the rights of the Disbursement Agent with respect
        to all such cash and Investments to the successor Disbursement Agent.
        After any retiring Disbursement Agent's resignation or removal
        hereunder as Disbursement Agent, the provisions of this Article shall
        continue in effect for its benefit in respect of any actions taken or
