      G. MSE has pledged the Special Account to TFC and has given TFC exclusive
control over the same subject to the payment procedures set forth herein.

      H. This Memorandum is, among other things, to establish the payment
procedures for payments to be made to Consortium Members from funds received
from DISD and/or USAC under the Master DISD Agreement.

                           Procedures and Agreements:

1. The background statements above are made a part of this Memorandum.

2. All goods and services to be supplied to the DISD under the Master DISD
Agreement by MSE and the Consortium Members will be ordered by DISD through MSE,
as the central ordering entity, and MSE will, as provided in the Letter
Agreements and other agreements and ordering arrangements between MSE and each
Consortium Member, order such goods and services from the Consortium Members
and/or supply the same itself.

3. Goods and services ordered by MSE from the Consortium Members will be
supplied by the Consortium Members to the DISD as provided for in the Master
DISD Agreement and pursuant to the Letter Agreements and other agreements
between MSE and the Consortium Members.

4. All goods and services supplied directly to the DISD under the Master DISD
Agreement by any Consortium Member will be invoiced by such Consortium Member to
MSE. MSE will re-invoice such goods and services to DISD and USAC, as provided
in paragraph 5 below, and, upon MSE's receiving payment for such re-invoices
from the DISD or USAC as contemplated in paragraph 8 below (or otherwise from
TFC under the LSA as contemplated in paragraph 7 below), MSE will use such
funds, or cause such funds to be used, as provided herein to pay the underlying
invoices of such Consortium Member.

by MSE and the Consortium Members will be invoiced by MSE, as the central

the terms and provisions of the Master DISD Agreement. MSE agrees that invoices
that it generates to DISD and/or USAC as a result of its re-invoicing of
invoices from any particular Consortium Member will be invoiced separate from
invoices from other Consortium Members and will be re-invoiced by MSE to the
DISD and/or USAC in a manner which will enable MSE to provide each Consortium
Member and TFC with detailed, segregated reporting of its accounts receivables
from the DISD and USAC, segregating the accounts receivables that resulted from
each particular Consortium Member's invoices to MSE, as required in section 11.
hereof.

6. MSE has pledged the Special Account to TFC under the LSA and given TFC
exclusive control over it, and MSE has pledged all inventory and other goods
acquired by MSE from the Consortium Members under the Master DISD Agreement to
TFC as collateral under the LSA. Subject to the rights of each Consortium Member
under paragraphs 7 and 8 below (including, without limitation, the rights of
each such Consortium Member to receive payments under and as provided for in
paragraph 8 below), each such Consortium Member acknowledges and agrees to those
pledges and further agrees that its rights and interests in and to the Special
Account and such inventory and goods are junior and subordinate to those of TFC.

transfers of the same. TFC may in good faith rely on the information provided to
it in clauses (i) and (ii) above, and each of the parties hereto agrees that TFC
shall have no liability for any payments made under this Memorandum in
accordance with such information.

9. TFC agrees not to offset or otherwise claim as proceeds of collateral any
funds from the Special Account that are to be used by it to make payments to the

Account owing to MSE for goods and services provided by MSE on its own behalf
(i.e., not originating from a Consortium Member) to DISD under the Master DISD
Agreement or with respect to funds in or from the Special Account owing to MSE
for goods and services provided by Consortium Members to the extent that
invoices for such goods and services have been paid with proceeds of loans made
by TFC under the LSA or otherwise by MSE; all of such funds owing to MSE and the
portion of such funds equal to such loans will be paid to TFC for application to
obligations of MSE under the LSA.

agreed to perform, any of the duties and obligations of MSE under the Letter
Agreements owing to the Consortium Members. TFC has no obligation or duty to
collect any amounts owing to MSE by the DISD or USAC under the Master DISD
Agreement. TFC may request and prepare for each Consortium Member formal
releases from security interests and liens confirmed to TFC in any fax or e-mail
and each Consortium Member will execute and return the same promptly to TFC. TFC
has no fiduciary duty to MSE or the Consortium Members. MSE will continue to
have the fiduciary duties owing to the Consortium Members provided in the Letter
Agreements. No Consortium Member will have any rights or benefits under the LSA.

any Consortium Member or the DISD against MSE or any Consortium Member and TFC
will be entitled to take all such offsets into consideration in connection with
any payments made under this Memorandum. TFC may in good faith rely on any
statements and/or directions supplied by MSE with respect to such offsets, and
each of the parties hereto agrees that TFC shall not have any liability in
respect of any such offsets in connection with the performance of its duties
under this Memorandum. To the extent of any inconsistency between this
Memorandum and the Letter Agreements, the terms of this Memorandum will govern.

Consortium Member that has requested the same a report substantially in the form
of Schedule C attached hereto. Such report may form the basis of payments to be
made by TFC under paragraphs 7 and 8 above and any Consortium Member may comply
with the requirements of subclause (ii) of paragraph 7 or subclause (ii) of
paragraph 8 by initialing such report and sending the same to TFC (which may be
via facsimile transmission or as a PDF attachment to an e-mail). TFC may in good
faith rely on the information provided to it in such reports, and each of the
parties hereto agrees that TFC shall have no liability for any payments made
under this Memorandum in accordance with such information. The report will
include, at miniumum, MSE's invoice number, date and invoice amount to DISD
and/or USAC, and provide the information required to reconcile such reported MSE
invoices to the invoice(s) from the Consortium Member that were re-invoiced by
MSE to DISD or USAC. MSE agrees that TFC shall be allowed to share the
above-referenced reported information with the Consortium Members that such
reporting pertains to.

Memorandum must be brought in a court of competent jurisdiction in Houston,
Harris County, Texas and the parties hereto consent to such jurisdiction and
venue. This Memorandum may be executed by each party in a separate counterpart
of this Memorandum, each of which will be deemed an original but all of which
together will constitute one and the same instrument. For the avoidance of
doubt, this Memorandum shall be binding on the signatories hereto even if less
than all of the Consortium Members set forth on Schedule A attached to this
Memorandum shall become signatories hereto. If any provision of this Memorandum
is held to be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be impaired
thereby.
