    Section
      5.1. Default
      and Remedies.

     

    (a) If

      Event of Default occurs, then in each such case the Secured Party may declare
      the Obligations to be due and payable immediately, by a notice in writing to
      the
      Company, and upon any such declaration, the Obligations shall become immediately
      due and payable.

      occurrence of an Event of Default, the Secured Party shall be entitled to
      (i) receive all distributions with respect to the Property, (ii) cause
      the Property to be transferred into the name of the Secured Party or its

    Section
      5.2. Method
      of Realizing Upon the Property: Other Remedies.

     

    Upon
      the
      occurrence of an Event of Default, in addition to any rights and remedies
      available at law or in equity, the following provisions shall govern the Secured
      Party’s right to realize upon the Property:

     

    (a) Any
      item
      of the Property may be sold for cash or other value in any number of lots at
      brokers board, public auction or private sale and may be sold without demand,
      advertisement or notice (except that the Secured Party shall give the Company
      ten (10) days’ prior written notice of the time and place or of the
      time after which a private sale may be made (the “Sale
      Notice”)),

      or sales of the Property, the Company may bid for and purchase the whole or
      any
      part of the Property and, upon compliance with the terms of such sale, may
      hold,
      exploit and dispose of the same without further accountability to the Secured
      Party. The Company will execute and deliver, or cause to be executed and
      delivered, such instruments, documents, assignments, waivers, certificates,
      and
      affidavits and supply or cause to be supplied such further information and
      take
      such further action as the Secured Party reasonably shall require in connection
      with any such sale.

      cash
      being held by the Secured Party as Property and all cash proceeds received
      by
      the Secured Party in respect of, sale of, collection from, or other realization
      upon all or any part of the Property shall be applied as follows:

      pursuant to this Agreement, the Secured Party shall have all of the rights
      and
      remedies provided by law, including, without limitation, those under the Uniform
      Commercial Code as adopted and in effect in the State of Texas.

     

    (i) If
      the
      Company fails to pay such amounts due upon the occurrence of an Event of Default
      which is continuing, then the Secured Party may institute a judicial proceeding
      for the collection of the sums so due and unpaid, may prosecute such proceeding
      to judgment or final decree and may enforce the same against the Company and
      collect the monies adjudged or decreed to be payable in the manner provided
      by
      law out of the property of Company, wherever situated.

     

    (ii) The
      Company agrees that it shall be liable for any reasonable fees, expenses and
      costs incurred by the Secured Party in connection with enforcement, collection
      and preservation of the Transaction Documents, including, without limitation,
      reasonable legal fees and expenses, and such amounts shall be deemed included

      Company for the payment of the Obligations), shall be entitled and empowered,

      of the Secured Party (including any claim for the reasonable legal fees and
      expenses and other expenses paid or incurred by the Secured Party permitted
      hereunder) allowed in such judicial proceeding, and

     

    (ii) to
      collect and receive any monies or other property payable or deliverable on
      any
      such claims and to distribute the same; and any custodian, receiver, assignee,
      trustee, liquidator, sequestrator or other similar official in any such judicial
      proceeding is hereby authorized by the Company to make such payments to the
      Secured Party and, in the event that the Secured Party shall consent to the
      making of such payments, to pay to the Secured Party any amounts for expenses
      due it hereunder.
