  We are asking you to contact your clients for whom you hold Outstanding
Securities. For your use and for forwarding to those clients, we are enclosing
copies of the Prospectus, as well as a Letter of Transmittal and a Notice of
Guaranteed Delivery for each of the series of Outstanding Securities.

  We are also enclosing a printed form of letter which you may send to your
clients, with space provided for obtaining their instructions with regard to
the exchange offers. We urge you to contact your clients as promptly as
possible.

  The Prospectus and Letters of Transmittal provide for payment to Soliciting
Dealers of a solicitation fee of 2% of the face amount of accepted Outstanding
Securities solicited by such Soliciting Dealer. Please note that in order to
receive a solicitation fee with respect to any Outstanding Securities, the
Outstanding Securities must be tendered through DTC and each Soliciting Dealer
MUST take the following steps:

  1. The Soliciting Dealer must request a DTC Participant to submit the
     securities to be exchanged via DTC's Automated Tender Offer Program
     ("ATOP").

  2. Each day that a DTC Participant receives any such orders for exchange,
     it must:

    a. aggregate the orders, by class of security, for one separate
       submission to ATOP for each class of securities that it receives
       orders; and

    b. send one email to uss_exchange@gs.com for each ATOP entry it makes,
       which must include the following:
      i.  information from ATOP ticket fields:
              1.  Target CUSIP Number,
              2.  Description of Securities,
              3.  Contra CUSIP Number,
              4.  VOI number,
              5.  Sequence Number,
              6.  Quantity,
              7.  Participant Name and Telephone Number, and
              8.  Contact Name and Telephone Number; and

      ii.  information regarding each Soliciting Dealer on whose behalf
           the ATOP entry was made:
              1.  the Soliciting Dealer's name,
              2.  the number of Outstanding Securities tendered by the
                  Soliciting Dealer, and
              3.  a contact person's name, telephone number, and email
                  address. (This person will be contacted to provide
                  information on how to transfer applicable solicitation fees
                  for Outstanding Securities tendered by that Soliciting
                  Dealer).

  3. In the event that a DTC Participant withdraws securities that have been
     submitted for exchange via ATOP, the DTC Participant must send an
     additional email, which sets forth the information above required under
     2(b).

  Each day, emails forwarded by the DTC Participants will be compared and
verified against a report that the Exchange Agent will prepare based on the
Outstanding Securities exchanged via ATOP. Solicitation fees will be paid only
upon reconciliation these reports. In the event of a discrepancy with respect
to reconciliation of the reports, Goldman Sachs & Co., the DTC Participant and
the Soliciting Dealer will jointly resolve the issue, although Goldman Sachs &
Co. reserves the right of final decision with respect to any such discrepancy.
However, if the email noted above is not properly completed and forwarded by
the DTC Participant, no fee will be paid to the Soliciting Dealer.

  In addition, please note that a Soliciting Dealer must first get approval
from the beneficial owner of the Outstanding Securities tendered to have
itself designated as the soliciting dealer for that tender. In order to
receive the soliciting dealer fee with respect to any tendered Outstanding
Securities, the email or Letter of Transmittal, as the case may be, must
relate to Outstanding Securities that have been validly tendered and not
withdrawn.
