    be necessary or desirable to complete the exchange, assignment
    and transfer of the Notes tendered hereby, and the undersigned

By tendering Notes and executing this Letter of Transmittal,
    the undersigned hereby represents and agrees that: (i) the
    undersigned is not an affiliate of BEXP, or if it is
    such an affiliate, that the Exchange Notes may not be offered
    for resale, resold or otherwise transferred without registration
    under and in compliance with the Prospectus delivery requirement
    of the Securities Act or an exemption therefrom, (ii) any
    Exchange Notes to be received by the undersigned are being
    acquired in the ordinary course of its business, (iii) the
    undersigned is not engaging in and does not intend to engage in
    a distribution (within the meaning of the Securities Act) of
    Exchange Notes to be received in the Exchange Offer,
    (iv) the undersigned has no arrangement or understanding
    with any person to participate in a distribution (within the
    meaning of the Securities Act) of Exchange Notes to be received
    in the Exchange Offer; (v) if the undersigned is not a
    broker-dealer, the undersigned is not engaged in, and does not
    intend to engage in, a distribution (within the meaning of the
    Securities Act) of such Exchange Notes, and (vi) the
    undersigned is not acting on behalf of any person or entity
    which could not truthfully make the above representations. By
    tendering notes pursuant to the Exchange Offer and executing
    this Letter of Transmittal, a holder of notes which is a
    broker-dealer represents, and agrees, consistent with certain
    interpretative letters issued by the staff of the Division of
    Corporate Finance of the Securities and Exchange Commission to
    third parties, that (A) such Notes held by the
    broker-dealer are held only as a nominee, or (B) such Notes
    were acquired by such broker-dealer for its own account as a
    result of market-making activities or other trading activities
    and it will deliver the Prospectus (as amended or supplemented
    from time to time) meeting the requirements of the Securities
    Act in connection with any resale of such Exchange Notes
    (provided that, by so acknowledging and by delivering a
    Prospectus, such broker-dealer will not be deemed to admit that
    it is an underwriter within the meaning of the
    Securities Act).
  BEXP has agreed that, subject to the provisions of the
    Registration Rights Agreement, the Prospectus, as it may be
    amended or supplemented from time to time, may be used by a
    participating broker-dealer (as defined below) in connection
    with resales of Exchange Notes received in exchange for Notes,
    where such Notes were acquired by such participating
    broker-dealer for its own account as a result of market-making
    activities or other trading activities, for a period ending on
    the earlier of (i) 180 days after the exchange offer
    registration statement is declared effective or (ii) the
    date on which a broker-dealer is no longer required to deliver a
    Prospectus in connection with market-making or other trading
    activities. In that regard, each broker-dealer who acquired
    notes for its own account as a result of market-making or other
    trading activities (a Participating Broker-Dealer),
    by tendering such Notes and executing this Letter of
    Transmittal, agrees that, upon receipt of notice from BEXP of
    the occurrence of any event or the discovery of any fact which
    makes any statement contained or incorporated by reference in
    the Prospectus untrue in any material respect or which causes
    the Prospectus to omit to state a material fact necessary to
    make the statements contained or incorporated by reference
    therein, in light of the circumstances under which they were
    made, not misleading or of the occurrence of certain other
    events specified in the registration rights agreement, such
    Participating Broker-Dealer will suspend the sale of Exchange
    Notes pursuant to the Prospectus until BEXP has amended or
    supplemented the Prospectus to correct such misstatement or
    omission and has furnished copies of the amended or supplemented
    Prospectus to the Participating Broker-Dealer or BEXP has given
    notice that the sale of Exchange Notes may be resumed, and the
    case may be. If BEXP gives such notice to suspend the sale of
    Exchange Notes, it shall extend the
    180-day or
    shorter period preferred to above during which Participating
    Broker-Dealers are entitled to use the Prospectus in connection
    with the resale of Exchange Notes by the number of days during
    the period from and including the date of the giving of such
    notice to and including the date when Participating
    Broker-Dealers shall have received copies of the supplemented or
    amended Prospectus necessary to permit resales of Exchange Notes
    or to and including the date on which BEXP has given notice that
    the sale of Exchange Notes may be resumed, as the case may
    be.
