Gentlemen:

In connection with the private placement of securities (the "Private Placement")
of U.S.  Wireless Data, Inc. (the "Company")  through  Commonwealth  Associates,
L.P. (the "Placement Agent"),  the undersigned hereby represents that during the
period  commencing on the date hereof and ending on the first anniversary of the
final closing of the Private  Placement  (the  "Initial  Lock-Up  Period"),  the
undersigned  will not sell,  transfer or otherwise  dispose of any securities of
the Company that are currently  held by the  undersigned or that are acquired by
the undersigned during the Initial Lock-Up Period;  provide,  however,  that the
undersigned  shall have the right to (i)  transfer  up to 159,000  shares of the
Company's  Common Stock to its  employees  without the consent of the  Placement
Agent,  and (ii) sell up to 980,000  shares  (the  "Saleable  Shares") of Common
Stock  commencing  upon the  earlier  of June 1, 2000 or 30 days after the final
closing of the  Offering,  provided  that the  undersigned  shall first give the
Placement  Agent written notice of its intent to sell any or all of the Saleable
Shares  and the  Placement  Agent  shall  have 30 days from the  receipt of such
written  notice to  arrange  for such  shares to be sold in one or more block or
private  transactions  that will result in a net price to the  undersigned of at
least $7 7/8 per share or such lower price as agreed to by the undersigned  (the
"Target Price").  In the event that the Placement Agent is unable to arrange for
the sale of the Saleable Shares at the Target Price within such 3 days, then the
undersigned  shall be free to sell such shares in the open  market or  otherwise
without the consent of the Placement Agent. In addition,  the undersigned agrees
that the Initial  Lock-Up Period may, at the discretion of the Placement  Agent,
be extended  for up to an  additional  six months from the closing of any public
offering which is consummated  prior to the end of the Initial  Lock-Up  Period,
provided  that the  Placement  Agent extends the lock-up of all investors in the
Offering for the same period.  In order to enforce  this  covenant,  the Company
will impose  stop-transfer  instructions  with respect to all  securities of the
Company that are currently  held by the  undersigned or that are acquired by the
undersigned  during the Lock-Up  Period,  except for 980,000 and 159,000  shares
mentioned above.

Notwithstanding  the foregoing,  if the undersigned is an individual,  he or she
may transfer any  securities of the Company either during his or her lifetime or
on death by will or intestacy to his or her immediate  family or to a custodian,
trustee (including a trustee of a voting trust), executor or other fiduciary for
the account of his or her immediate  family, a trust, the beneficiaries of which
are  exclusively  the  undersigned  and/or a  member  or  members  of his or her
immediate family, or a charitable reminder trust;  provided that such transferee
agrees to be bound by the provisions of this lock-up agreement. For the purposes
of this  paragraph,  "immediate  family" shall mean spouse,  lineal  descendant,
father,  mother,  brother or sister of the transferor,  or lineal  descendant of
brother or sister of the transferor.

Upon the execution  hereof,  this lock-up  agreement shall supercede any and all
other agreements with respect to the matter referred to herein.

     THIS REDEMPTION AGREEMENT, dated as of January 31, 2000 (this "Agreement"),
is made by and between U.S.  Wireless Data,  Inc., a Colorado  corporation  (the
"Company"),  and Bold Street,  LLC, a Cayman Islands limited  liability  company
(the "Holder").

                                    RECITALS

     A. The Company issued 1,500,000  shares of Series B Cumulative  Convertible
Redeemable  Preferred  Stock,  no par  value,  $1.00  (plus  accrued  dividends)
liquidation preference of the Company (the "Preferred Shares"), pursuant to that
certain Securities Purchase  Agreement,  dated as of April 30, 1999, between the
Holder and the Company (the "Securities Purchase Agreement").  Capitalized terms
not  otherwise  defined  herein shall have the meanings  ascribed to them in the
Securities Purchase Agreement.

     B. The Preferred  Shares are  convertible  into shares of Common Stock (the
"Conversion  Shares") upon the terms and subject to the conditions  contained in
the Certificate of Designation for the Preferred Shares.

     C.  The  Company  agreed  to  register  the  Conversion  Shares  and  other
securities, including, without limitation, the shares issuable upon the exercise
of that certain  Warrant,  dated as of April 30, 1999,  issued by the Company to
Holder (the "Original  Warrant") with the Securities and Exchange  Commission on
Form SB-2, pursuant to that certain  Registration Rights Agreement,  dated as of
April 30,  1999,  between the Holder and the Company (the  "Registration  Rights
Agreement")  and to pay a three percent (3%) per month penalty in the event that
such registration was not effective on or before July 29, 1999.

     D. The penalty accrued as of the date hereof  pursuant to the  Registration
Rights Agreement equals the sum of $270,000 (the "Accrued Penalty").

     E. The Escrow  Agent (as  defined  in the  Securities  Purchase  Agreement)
retained in a trust  account  the sum of $45,000  (the  "Registration  Hold Back
Amount")  which  was to be paid  on  behalf  of the  Company  to its  securities
attorneys,  the  firm of  Ireland  Stapleton,  upon  the  effective  date of the
registration  of  Conversion  Shares,  which  amount has not been paid from said
trust account.

     F. The Holder has agreed,  pursuant to the terms hereof,  to the redemption
by the Company of the Preferred Stock and in consideration  therefor the Company
has  agreed  to  issue  additional  warrants  to  the  Holder  and  release  the
Registration Hold Back Amount to or on behalf of the Holder.

     NOW,  THEREFORE,  in consideration of the premises and the mutual covenants
contained  herein and other good and  valuable  consideration  the  receipt  and
sufficiency of which are hereby acknowledged,  the Company and the Holder hereby
agree as follows:

<PAGE>

     1. Redemption.

          (a) On condition that the Company (and Ireland  Stapleton)  authorizes
the release of the  Registration  Hold Back Amount pursuant to paragraph 2 below
and in consideration  therefor,  the Holder hereby agrees that at any time on or
before March 31, 2000, the Company may redeem the Preferred  Stock for an amount
(the  "Redemption  Amount") equal to (i) One Million Eight Hundred  Seventy Five
Thousand Dollars  $1,875,000 (125% of the Stated Value),  plus accrued dividends
on the date of the Redemption is consummated (the "Redemption  Date"), less (ii)
$43,500 of the  Redemption  Hold Back Amount paid pursuant to paragraph 2 below.
As  additional  consideration  for  Holder's  conditional  waiver  of  penalties
provided for in paragraph 1(b) below,  upon the  consummation  of the redemption
(and as a  condition  thereto)  the Company  shall issue a warrant,  in the form
attached hereto as Exhibit A (the  "Redemption  Warrant"),  to purchase  150,000
shares of the Company's  Common Stock,  at an exercise price equal to the lesser
of the closing bid price (as  reported by  Bloomberg)  of the  Company's  Common
Stock on (i) the date hereof or (ii) the business day  immediately  prior to the
Redemption Date.

          (b) On the condition that the redemption of the Preferred  Shares (the
"Redemption") is consummated pursuant to the terms hereof on or before March 31,
2000,  Holder hereby agrees to waive the Accrued  Penalty and other sums arising
from Company's failure to timely register the Conversion Shares.  Time is of the
essence with respect to the  consummation  of the  redemption  of the  preferred
Shares by March 31,  2000 as a  condition  to the  foregoing  waiver of  Accrued
Penalties. If the Company fails to redeem the Preferred Stock on or before March
31, 2000,  the Holder's  waiver of the Accrued  Penalty,  all other sums arising
from the  failure to  register  the  Conversion  Shares  (including  the further
accruing of penalties during the calendar months of February and March) shall be
payable in full by the Company,  less $43,500,  the Redemption  Hold Back Amount
applied to penalties pursuant to paragraph 2 hereof.

          (c) On the  condition  that the  Company is not in default  hereunder,
Holder agrees not to sell, transfer,  assign, otherwise convert or dispose of or
encumber or hypothecate the Preferred Shares prior to March 31, 2000.

          (d) The Company  shall provide  written  notice to Holder at least two
(2) business  days prior to the  Redemption  Date and shall wire the  Redemption
Amount to the trust account of an attorney  designated by Holder (within two (2)
business days after receipt of Company's Notice),  who shall hold the Redemption
Amount in trust until it receives (i) the origins  certificate for the Preferred
Shares, with duly executed stock powers from the Holder, (ii) an original of the
Redemption  Warrant from the Company (iii) and all other  documents  (i.e.  form
escrow  instructions)  such  attorney  may  reasonably  require to disburse  the
Redemption  Amount and the Redemption  Warrant to the Holder and the certificate
for the Preferred  Shares,  with duly executed stock powers to the Company.  All
notices shall be sent as set forth in the Securities Purchase Agreement.

     2. Payment of Registration Hold Back Amount.

          (a)  Upon  the  full  execution  hereof,   the  Company  (and  by  its
acknowledgment  hereof,  Ireland Stapleton Pryor Pascoe, P.C.) hereby authorizes
and  instructs  the Escrow  Agent to release  from its trust  account to the Law

                                       2

Offices of Michael S.  Rosenblum,  the sum of One Thousand Five Hundred  Dollars
($1,500), for legal fees incurred by Holder in connection with the documentation
of this Agreement.

          (b)  Upon  the  full  execution  hereof,   the  Company  (and  by  its
acknowledgment  hereof,  Ireland Stapleton Pryor Pascoe, P.C.) hereby authorizes
and  instructs  the Escrow Agent to release from its trust account to Holder the
sum of $43,500 to be applied to penalties  due pursuant to paragraph  ___ of the
Registration  Statement  for the  Company's  failure to Register the  Conversion
Shares on or before July 29, 1999. If the Preferred Shares are Redeemed pursuant
to paragraph 1 on or before  March 31, 2000 hereof (time being of the  essence),
all  penalties  which have accrued  under the  Registration  Statement  shall be
waived,  and the $43,500 shall be applied to the  redemption  of the  Conversion
Shares pursuant to paragraph 1(a) above.

subsidiaries,  taken as a whole.  The Company has  registered  its Common  Stock
pursuant  to  Section  12 of the 1934 Act,  and the  Common  Stock is listed and

any  material  fact  required  to be stated  therein  or  necessary  to make the
statements  made  therein in light of the  circumstances  under  which they were
made, not misleading, except as corrected by an amended filing made prior to the
date hereof.  As of the date of this Agreement,  the Company is current with all
requisite  forms,  reports (and exhibits  thereto)  which it is required to file

          (g) Full Disclosure. There is no fact known to the Company (other than
general economic conditions known to the public generally or as disclosed in the
Company's  SEC  Reports),  that has not been  disclosed in writing to the Holder
that (i) would  reasonably be expected to have a material  adverse effect on the
business  or  financial  condition  of the Company or (ii) would  reasonably  be

on the  properties,  business or  financial  condition,  results of operation or
prospects of the Company and its subsidiaries,  the transactions contemplated by
this Agreement,  or which would adversely affect the validity or  enforceability
of, or the authority or ability of the Company to perform its obligations under,
this Agreement.

          (i)  Absence  of  Events  of  Default.  No  Event of  Default  (or its

in such agreement), has occurred and is continuing,  which would have a material
adverse effect on the Company's financial condition or results of operations.

          (a) The  Company  acknowledges  and agrees that it has  requested  the
Holder to enter into this  Agreement to facilitate  the equity  financing of the
Company by a third party and that Holder has entered  into this  Agreement as an
accommodation to the Company.  The Company is not aware of any claims,  defenses
or offsets that excuse its performance under the Securities  Purchase Agreement,
the Registration Rights Agreement,  the Original Warrant or any other agreements
entered into in connection  therewith (the  "Convertible  Documents") and to the
extent that any such claims, defenses or offsets exist it hereby irrevocably and
unconditionally  waives  them to the  fullest  extent  permitted  by the law. In
furtherance  thereof and as a condition of Holder's entering into this Agreement
and except for the performance by the Holder of the provisions of this Agreement
and  further  except  for  the  representations  and  warranties  of the  Holder
contained  herein  (which  representations,  warranties  and  indemnities  shall
survive the  consummation  of this  Agreement  and as to which the parties shall
continue to be liable),  the Company, for itself and on behalf of all direct and
indirect partners, officers, directors,  employees, affiliates (both persons and

<PAGE>

predecessors in interest, successors in interest, assigns, nominees and insurers
(collectively,  the  "Company  Releasing  Parties"),  shall  be  deemed  to have
released  and  forever  discharged  the  Holder,  and all  direct  and  indirect
partners,  officers,   directors,   employees,   affiliates  (both  persons  and
entities), agents,  representatives (including investment advisors and managers)
servants,  trustees,  beneficiaries,  predecessors  in interest,  successors  in
interest, assigns, nominees and insurers of each such party, of and from any and
all claims,  demands,  actions and causes of action,  whether  known or unknown,
fixed or contingent, that any of the Company Releasing Parties may have had, may
now have or may hereafter acquire with respect to any matters whatsoever arising
under or in any way related to (i) the Convertible  Documents,  and (ii) any act
which may constitute a defense or offset to its  performance of the  Convertible
Documents.

          (b) Upon the consummation of the redemption by the Company pursuant to
the terms  hereof on or before  March 31, 2000 (time being of the  essence)  and
except for the  performance by the Company of the provisions of this  Agreement,

representations   and   warranties  of  the  Holder   contained   herein  (which
representations,  warranties and indemnities  shall survive the  consummation of
this  Agreement  and as to which the parties shall  continue to be liable),  the
Holder, for itself and on behalf of all direct and indirect partners,  officers,
directors, employees,  affiliates (both persons and entities),  representatives,
agents, servants, trustees, beneficiaries,  predecessors in interest, successors
in interest, assigns, nominees and insurers (collectively, the "Holder Releasing
Parties"),  shall be deemed to have released and forever discharged the Company,

nominees  and  insurers  of each  such  party,  of and from any and all  claims,

contingent,  that any of the Holder Releasing Parties may have had, may now have
or may hereafter acquire with respect to any matters whatsoever arising under or
in any way related to the Convertible Documents. Notwithstanding anything to the
contrary  contained herein,  the foregoing release shall not release the Company
from any claims,  demands,  expenses or losses by the Holder Releasing Parties (
or causes of action or remedies  related thereto) arising from (i) the breach by
the Company of covenants and obligations  contained in the Convertible Documents
which  require  it to file and  maintain  the  effectiveness  of a  Registration
Statement for the shares  issuable upon exercise of the Original  Warrant,  (ii)
any  indemnity  by the Company for the benefit of the Holder  Releasing  Parties
contained in the Conversion Documents, or (iii) any breach by the Company of the

the essence) this Release shall be null and void.

he/she/it has not, and at the time this release becomes effective will not have,
sold, assigned,  transferred or otherwise conveyed to any other person or entity
all or any portion of its rights, claims,  demands,  actions or causes of action
herein released.

     Each of the parties  hereto  acknowledges  that it is familiar with Section
1542 of the Civil Code of the State of California, which provides as follows:

          does not  know or  suspect  to exist in his  favor at the time of
          executing the release, which if known by him must have materially
          affected his settlement with the debtor."

Each of the parties hereto hereby waives any and all rights and benefits that it
now has or in the  future  may have  under  Section  1542 of the Civil Code (and
under the  comparable  provisions  of any other  applicable  law) and agrees and
acknowledges  that this Agreement  contains a full and final release applying to
unknown and unanticipated claims, injuries or damages arising out of the subject
matter hereof, as well as to those now known or disclosed.

Each  party  represents  and  warrants  that it has relied  wholly  upon its own
judgment,  belief and knowledge of the existence,  nature, extent or duration of
any claim,  demand, debt, damage,  liability,  account,  reckoning,  obligation,
cost, expense, cause of action, chosen action, right of indemnity,  agreement or
promise that it may have against the released  parties and that it has made full
investigations  with  respect to potential  rights and claims  released and that
such releasing party has not been influenced to any extent  whatsoever in making
the releases  contemplated by this agreement by any  representation or statement
regarding any such matter. Each party further represents and warrants that it is
executing and delivering this Agreement and the releases contemplated  hereunder
after having received full legal advice as to its rights hereunder and the legal
effect  thereof  from legal  counsel of its own  choosing.  Notwithstanding  the
above, this Agreement is not intended to and does not, release or extinguish the
rights of any of the parties to enforce this Agreement.
