                            EXCHANGE AGENT AGREEMENT

The Bank of New York
Corporate Trust Administration
101 Barclay Street - 21st Floor
New York, New York  10286

Ladies and Gentlemen:

               Bank United Corp., formerly named USAT Holdings, Inc. (the
"Company"), proposes to make an offer (the "Exchange Offer") to exchange its
8.05% Senior Notes due May 15, 1998 (the "Old Notes") for its 8.05% Senior Notes
due May 15, 1998 (the "New Notes"), respectively. The terms and conditions of
the Exchange Offer as currently contemplated are set forth in a prospectus,
dated ____________, 1996 (the "Prospectus"), proposed to be distributed to all
record holders of the Old Notes. The Old Notes and the New Notes are
collectively referred to herein as the "Notes".

               The Company hereby appoints The Bank of New York to act as
exchange agent (the "Exchange Agent") in connection with the Exchange Offer.
References hereinafter to "you" shall refer to The Bank of New York.

               The Exchange Offer is expected to be commenced by the Company on
or about _________, 1996. The Letter of Transmittal accompanying the Prospectus
is to be used by the holders of the Old Notes to accept the Exchange Offer, and
contains instructions with respect to the delivery of certificates for Old Notes
tendered.

               The Exchange Offer shall expire at 5:00 P.M., New York City time,
on _____________, 1996 or on such later date or time to which the Company may
extend the Exchange Offer (the "Expiration Date"). Subject to the terms and
conditions set forth in the Prospectus, the Company expressly reserves the right
to extend the Exchange Offer by giving oral (confirmed in writing) or written
notice to you at any time or from time to time before 5:00 P.M., New York City
time, on the business day theretofor scheduled as the Expiration Date.

               In carrying out your duties as Exchange Agent, you are to act in
accordance with the following instructions:

               1. You will perform such duties and only such duties as are
specifically set forth in the section of the Prospectus captioned "The Exchange
Offer", in the Letter of Transmittal or as specifically set forth herein;
provided, however, that in no way will your general duty to act in good faith be
discharged by the foregoing.

               2. You will establish an account with respect to the Old Notes at
the Depository Trust Company (the "Book-Entry Transfer Facility") for purposes
of the Exchange Offer within two business days after the date of the Prospectus,
and any financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of the Old Notes by causing the
Book-Entry Transfer Facility to transfer such Old Notes into your account in
accordance with the Book-Entry Transfer Facility's procedure for such transfer.

               3. You are to date and time stamp each Letter of Transmittal and
other documents when received and examine each of the Letters of Transmittal and
certificates for Old Notes (or confirmation of book-entry transfer into your
account at the Book-Entry Transfer Facility) and any other documents delivered
or mailed to you by or for holders of the Old Notes to ascertain whether: (i)
the Letters of Transmittal and any such other documents are duly executed and
properly completed in accordance with instructions set forth therein and (ii)
the Old Notes have otherwise been properly tendered. In each case where the
Letter of Transmittal or any other document has been improperly completed or
executed or any of the certificates for Old Notes are not in proper form for
transfer, or have been improperly tendered or some other irregularity in
connection with the acceptance of the Exchange Offer exists, you will endeavor
to inform the presenters of the need for fulfillment of all requirements and to
take any other action as may be necessary or advisable to cause such
irregularity to be corrected.

               4. With the approval of the President, any Executive Vice
President, or any Vice President of the Company (such approval, if given orally,
to be confirmed in writing) or any other party designated by such an officer in
writing, you are authorized to waive any irregularities in connection with any
tender of Old Notes pursuant to the Exchange Offer.

               5. Tenders of Old Notes may be made only as set forth in the
Letter of Transmittal and in the Section of the Prospectus captioned "The
Exchange Offer -- How to Tender," and Old Notes shall be considered properly
tendered to you only when tendered in accordance with the procedures set forth
therein.

               Notwithstanding the provisions of this paragraph 5, Old Notes
which the President, and Executive Vice President, or any Vice President of the
Company shall approve as having been properly tendered shall be considered to be
properly tendered (such approval, if given orally, shall be confirmed in
writing).

               6. You shall advise the Company with respect to any Old Notes
received subsequent to the Expiration Date and accept its instructions with
respect to disposition of such Old Notes.

               7.     You shall consider Old Notes improperly tendered:

                      (a) in cases where the Old Notes are registered in two or
more names unless signed by all named holders;

                      (b) in cases where the signing person (as indicated on the
Letter of Transmittal) is acting in a fiduciary or a representative capacity
unless when proper evidence of his or her authority so to act is submitted; and

                      (c) if tendered by persons other than the registered
holder of Old Notes unless customary transfer requirements, including any
applicable transfer taxes, are fulfilled.

               You shall consider properly tendered partial tenders of Old Notes
where so indicated and as permitted in the Letter of Transmittal and splitup and
return any untendered Old Notes to the holder (or such other person as may be
designated in the Letter of Transmittal) as promptly as practicable after
expiration or termination of the Exchange Offer.

               8. Upon satisfaction or waiver of all of the conditions to the
Exchange Offer, the Company will notify you (such notice if given orally, to be
confirmed in writing) of its acceptance, promptly after the Expiration Date, of
all Old Notes properly tendered and you, on behalf of the Company, will exchange
such Old Notes for New Notes and cause such Old Notes to be cancelled. Delivery
of New Notes will be made by mail on behalf of the Company by you, at the rate
of $1,000 principal amount of New Notes for each $1,000 principal amount of the
corresponding series of Old Notes tendered and accepted promptly after notice of
acceptance of said Old Notes by the Company (such notice if given orally, to be
confirmed in writing). Unless otherwise instructed by the Company in writing,
you shall issue New Notes only in denominations of $1,000 or any integral
multiple thereof.

               9. Tenders pursuant to the Exchange Offer are irrevocable, except
that, subject to the terms and upon the conditions set forth in the Prospectus
and the Letter of Transmittal, Old Notes tendered pursuant to the Exchange Offer
may be withdrawn at any time prior to acceptance thereof on the Expiration Date,
and you shall promptly notify the Company of any withdrawals.

               10. The Company shall not be required to accept any Old Notes
tendered for exchange if any of the conditions set forth in the Exchange Offer
are not met. Notice of any decision by the Company not to accept any Old Notes
tendered for exchange shall be given (and confirmed in writing) by the Company
to you.

               11. If, pursuant to the Exchange Offer, the Company does not
accept for exchange all or part of the Old Notes tendered because of an invalid
tender, the occurrence of certain other events set forth in the Prospectus under
the caption "The Exchange Offer -- Conditions" or otherwise, you shall as soon
as practicable after the expiration or termination of the Exchange Offer return
or effect appropriate book-entry transfer of unaccepted Old Notes, together with
any related required documents and the Letters of Transmittal relating thereto
that are in your possession, to the persons who deposited them.

               12. All certificates for reissued Old Notes, unaccepted Old Notes
or for New Notes shall be forwarded by (a) first-class certified mail, return
receipt requested under a blanket surety bond protecting you and the Company
from loss or liability arising out of the non-receipt or non-delivery of such
certificates or (b) by registered mail insured separately for the replacement
value of each of such certificates.

               13. You are not authorized to pay or offer to pay any
concessions, commissions or solicitation fees to any broker, dealer, bank or
other persons or to engage or utilize any person to solicit tenders.

               14.    As Exchange Agent hereunder you:

                      (a) shall have no duties or obligations other than those
specifically set forth herein or as may be subsequently agreed to in writing by
you and the Company;

                      (b) will be regarded as making no representations and
having no responsibilities as to the validity, sufficiency, value or genuineness
of any of the certificates or the Old Notes represented thereby deposited with
you pursuant to the Exchange Offer, and will not be required to and will make no
representation as to the validity, value or genuineness of the Exchange Offer;
PROVIDED, HOWEVER, that in no way will your general duty to act in good faith be
discharged by the foregoing;

                      (c) shall not be obligated to take any legal action
hereunder which might in your reasonable judgment involve any expense or
liability, unless you shall have been furnished with reasonable indemnity;

                      (d) may reasonably rely on and shall be protected in
acting in reliance upon any certificate, instrument, opinion, notice, letter,
telegram or other document or security delivered to you and reasonably believed
by you to be genuine and to have been signed by the proper party or parties;

                      (e) may reasonably act upon any tender, statement,
request, comment, agreement or other instrument whatsoever not only as to its
due execution and validity and effectiveness of its provisions, but also as to
the truth and accuracy of any information contained therein, which you shall in
good faith believe to be genuine or to have been signed or represented by a
proper person or persons;

                      (f) may rely on and shall be protected in acting upon
written or oral instructions from any person described in paragraph 4 above;

                      (g) may consult with your counsel with respect to any
questions relating to your duties and responsibilities and the written opinion
of such counsel shall be full and complete authorization and protection in
respect of any action taken, suffered or omitted to be taken by you hereunder in
good faith and in accordance with the written opinion of such counsel; and

                      (h) shall not advise any person tendering Old Notes
pursuant to the Exchange Offer as to the wisdom of making such tender or as to
the market value or decline or appreciation in market value of any Old Notes.

               15. You shall take such action as may from time to time be
requested by the Company or its counsel (and such other action as you may
reasonably deem appropriate) to furnish copies of the Prospectus, Letter of
Transmittal and the Notice of Guaranteed Delivery or such other forms as may be
approved from time to time by the Company, to all persons requesting such
documents and to accept and comply with telephone requests for information
relating to the Exchange Offer, provided that such information shall relate only
to the procedures for accepting (or withdrawing from) the Exchange Offer. The
Company will furnish you with copies of such documents at your request. All
other requests for information relating to the Exchange Offer shall be directed
to Jonathan K. Heffron, Executive Vice President, Chief Operating Officer and
General Counsel of the Company, at (516) 745-6644.

               16. You shall advise by cable, telex, facsimile transmission or
telephone, and promptly thereafter confirm in writing to Jonathan K. Heffron,
Executive Vice President, Chief Operating Officer and General Counsel of the
Company, and such other person or persons as it may request, daily (and more
frequently during the week immediately preceding the Expiration Date and if
otherwise requested) up to and including the Expiration Date, as the number of
Old Notes which have been tendered (and withdrawn, if any) pursuant to the
Exchange Offer and the items received by you pursuant to this Agreement,
separately reporting and giving cumulative totals as to items properly received
and items improperly received. In addition, you will also inform, and cooperate
in making available to, the Company or any such other person or persons upon
oral request made from time to time prior to the Expiration Date of such other
information as it or he reasonably requests. Such cooperation shall include,
without limitation, the granting by you to the Company and such person as the
Company may request of access to those persons on your staff who are responsible
for receiving tenders, in order to ensure that immediately prior to the
Expiration Date the Company shall have received information in sufficient detail
to enable it to decide whether to extend the Exchange Offer. You shall prepare a
final list of all persons whose tenders were accepted, the aggregate principal
amount of Old Notes tendered (and withdrawn, if any), the aggregate principal
amount of Old Notes accepted and deliver said list to the Company.

               17. Letters of Transmittal and Notices of Guaranteed Delivery
shall be stamped by you as to the date and the time of receipt thereof and shall
be preserved by you for a period of time at least equal to the period of time
you preserve other records pertaining to the transfer of securities. You shall
dispose of unused Letters of Transmittal and other surplus materials by
returning them to the Company.

               18. You hereby expressly waive any lien, encumbrance or right of
set-off whatsoever that you may have with respect to funds deposited with you
for the payment of transfer taxes by reasons of amounts, if any, borrowed by the
Company, or any of its subsidiaries or affiliates pursuant to any loan or credit
agreement with you or for compensation owed to you hereunder.

               19. For services rendered as Exchange Agent hereunder, you shall
be entitled to such compensation as set forth on Schedule I attached hereto.

               20. You hereby acknowledge receipt of the Prospectus and the
Letter of Transmittal attached hereto and further acknowledge that you have
examined each of them. Any inconsistency between this Agreement, on the one
hand, and the Prospectus and the Letter of Transmittal (as they may be amended
from time to time), on the other hand, shall be resolved in favor of the latter
two documents, except with respect to the duties, liabilities and
indemnification of you as Exchange Agent which shall be controlled by this
Agreement.

               21. The Company covenants and agrees to indemnify and hold you
harmless in your capacity as Exchange Agent hereunder against any loss,
liability, cost or expense, including reasonable attorneys' fees arising out of
or in connection with any act, omission, delay or refusal made by you in
reasonable reliance upon any signature, endorsement, assignment, certificate,
order, request, notice, instruction or other instrument or document reasonably
believed by you to be valid, genuine and sufficient and in accepting any tender
or effecting any transfer of Old Notes reasonably believed by you in good faith
to be authorized, and in delaying or refusing in good faith to accept any
tenders or effect any transfer of Old Notes; provided, however, that the Company
shall not be liable for indemnification or otherwise for any loss, liability,
cost or expense to the extent arising out of your gross negligence, willful
misconduct or bad faith. In no case shall the Company be liable under this
indemnity with respect to any claim against you unless the Company shall be
notified by you, by letter or cable or by facsimile confirmed letter, of the
written assertion of a claim against you or of any other action commenced
against you, promptly after you shall have received any such written assertion
or commencement of action. The Company shall be entitled to participate at its
own expense in the defense of any such claim or other action, and, if the
Company so elects, the Company shall assume the defense of any suit brought to
enforce any such claim. In the event that the Company shall assume the defense
of any such suit, the Company shall not be liable for the fees and expenses of
any additional counsel thereafter retained by you so long as the Company shall
retain counsel reasonably satisfactory to you to defend such suit.

               22. You shall arrange to comply with all requirements under the
tax laws of the United States, including those relating to missing Tax
Identification Numbers, and shall file any appropriate reports with the Internal
Revenue Service. The Company understands that you are required to deduct 31% on
payments to holders who have not supplied their correct Taxpayer Identification
Number or required certification, and that such percentage may be changed from
time to time. Such funds will be turned over to the Internal Revenue Service in
accordance with applicable regulations.

               23. You shall deliver or cause to be delivered, in a timely
manner to each governmental authority to which any transfer taxes are payable in
respect of the exchange of Old Notes, your check in the amount of all transfer
taxes so payable, and the Company shall reimburse you for the amount of any and
all transfer taxes payable in respect of the exchange of Old Notes; provided,
however, that you shall reimburse the Company for amounts refunded to you in
respect of your payment of any such transfer taxes, at such time as such refund
is received by you.

               24. This Agreement and your appointment as Exchange Agent
hereunder shall be construed and enforced in accordance with the laws of the
State of New York applicable to agreements made and to be performed entirely
within such state, and shall inure to the benefit of the successors and assigns
of each of the parties hereto. This Agreement may not be modified orally.

               25. This Agreement may be executed in two or more counterparts,
each of which shall be deemed to be an original and all of which taken together
shall constitute one and the same agreement.

               26. In case any provision of this Agreement shall be invalid,
illegal or unenforceable, the validity, legality and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby.

               27. This Agreement shall not be deemed or construed to be
modified, amended, rescinded, cancelled or waived, in whole or in part, except
by a written instrument signed by a duly authorized representative of the party
to be charged.

               28. Unless otherwise provided herein, all notices, requests and
other communications to any party hereunder shall be in writing (including
facsimile or similar writing) and shall be given to such party, addressed to it,
