     WHEREAS, the Company desires to issue a maximum of 250 units ("Units") in a
private placement (the  "Offering"),  each Unit consisting of: (i) 10,000 shares
of Series C Convertible Preferred Stock (the "Preferred Shares"), each Preferred

Incorporation including the Designation of Series C Convertible Preferred Stock;
and (ii) seven-year  warrants (the  "Warrants") to purchase a minimum of 100,000
shares of Common  Stock,  pursuant  to the form of a Warrant  Agreement,  on the
terms and conditions hereinafter set forth; and

     WHEREAS, the Subscriber desires to acquire the number of Units set forth on
the signature page hereof.

     NOW,  THEREFORE,  for and in  consideration  of the premises and the mutual
covenants hereinafter set forth, the parties hereto agree as follows:

     I.  SUBSCRIPTION  FOR  UNITS  AND   REPRESENTATIONS  BY  AND  COVENANTS  OF
         SUBSCRIBER

          1.1 Subject to the terms and  conditions  hereinafter  set forth,  the
Subscriber  hereby  subscribes  for and agrees to purchase from the Company such
number of Units as is set forth upon the signature  page hereof at a price equal
to $100,000 per Unit and the Company agrees to sell such Units to the Subscriber
for  said  purchase  price,  subject  to the  Company's  right  to  sell  to the
Subscriber  such  lesser  number  of  Units  as the  Company  may,  in its  sole
discretion,  deem  necessary  or  desirable.  The  purchase  price is payable by
certified  or bank  check  made  payable  to  "American  Stock  Transfer & Trust
Company,  as escrow agent for U.S.  Wireless Data,  Inc." or by wire transfer of
funds,  contemporaneously  with the execution and delivery of this  Subscription
Agreement.  This  Agreement  shall not be  binding  on the  Company  until it is
accepted by the Subscriber's offer in writing. The Preferred Shares and Warrants
will be delivered by the Company  within 10 days following the  consummation  of
this offering as set forth in Article III hereof.

          1.2 The  Subscriber  recognizes  that the purchase of Units involves a
high degree of risk in that (i) the Company has incurred substantial losses from
operations;  (ii) an  investment in the Company is highly  speculative  and only
investors  who can afford the loss of their entire  investment  should  consider
investing  in the Company  and the Units;  (iii) an  investment  in the Units is
illiquid;  and (iv)  transferability  of the securities  comprising the Units is
extremely limited,  as well as other risk factors as more fully set forth in the
Memorandum.





          1.3 The  Subscriber  represents and warrants that it is an "accredited
investor" as such term in defined in Rule 501 of Regulation D promulgated  under
the  Securities  Act of 1933,  as  amended  (the  "Act"),  as  indicated  by its
responses to the confidential investor questionnaire (the "Questionnaire"),  and
that it is able to bear the economic  risk of an  investment  in the Units.  The
Subscriber further represents and warrants that the information furnished in the
Investor Questionnaire is accurate and complete in all material respects.

          1.4 The Subscriber represents and warrants that the Subscriber did not
learn of the Offering directly or indirectly through any general solicitation or
advertising,  including,  but not  limited  to,  learning  of the Company or the
Offering as a result of viewing any press  releases or similar types of publicly
available  information  which directly or indirectly  resulted in the subscriber
subscribing for Units in the Offering.  The Subscriber further  understands that
the Company is relying,  in part, on this  representation  to ensure  compliance
with the federal securities laws.

          1.5  The  Subscriber   acknowledges   that  it  has  prior  investment
experience, including investment in non-listed and non-registered securities and
that it recognizes the highly speculative nature of this investment.

          1.6 The  Subscriber  acknowledges  receipt and  careful  review of the
Memorandum and all other documents furnished in connection with this transaction
(collectively,  the "Offering Documents") and hereby represents that it has been
furnished  by the  Company  during  the  course  of this  transaction  with  all
information regarding the Company which it has requested or desires to know; and
that  such  information  and  documents  have,  in  its  opinion,  afforded  the
Subscriber  all  of  the  same  information  that  would  be  provided  him in a
registration  statement  filed  under  the Act;  that it has been  afforded  the
opportunity  to ask  questions  of and  receive  answers  from  duly  authorized
officers  or other  representatives  of the  Company  concerning  the  terms and
conditions  of  the  Offering,  and  any  additional  information  which  it had
requested.  The Subscriber  represents and warrants that it is relying solely on
the  information  contained in the Memorandum  and obtained  through its own due
diligence.

          1.7 The  Subscriber  acknowledges  that  this  offering  of Units  may
involve tax  consequences and that the contents of the Memorandum do not contain
tax advice or information.  The Subscriber  acknowledges that it must retain its
own  professional  advisors to  evaluate  the tax and other  consequences  of an
investment in the Units.

          1.8 The Subscriber  acknowledges  that the Units are being offered and
sold in reliance upon the exemption from  registration  provided by Section 4(2)
of the Act and  provisions  of Regulation D of the Act, and the Offering has not
been reviewed by the United States Securities and Exchange  Commission  ("SEC").
The Subscriber  represents that the Preferred Shares and Warrants comprising its
Units  are being  purchased  for its own  account,  for  investment  and not for
distribution or resale to others. The Subscriber agrees that it will not sell or
otherwise  transfer  the  Preferred  Shares  or the  Warrants  unless  they  are
registered  under the Act or  unless an  exemption  from  such  registration  is
available.


                                       2





          1.9 The  Subscriber  understands  that,  except for the Common  Stock,
there  is  no  public  market  for  the  Company's  securities.  The  Subscriber
understands that Rule 144 (the "Rule") promulgated under the Act requires, among
other  conditions,  a one year  holding  period  prior to the resale (in limited
amounts) of  securities  acquired in a  non-public  offering  without  having to
satisfy the registration  requirements under the Act. The Subscriber understands
that the Company makes no representation  or warranty  regarding its fulfillment
in the future of any reporting requirements under the Securities Exchange Act of
1934, as amended, or its dissemination to the public of any current financial or
other information  concerning the Company,  as is required by the Rule as one of
the  conditions  of its  availability.  The  Subscriber  understands  and hereby
acknowledges  that the Company is under no obligation to register the securities
comprising  the Units under the Act, with the exception of certain  registration
rights set forth in Article IV herein.  The  Subscriber  agrees that the Company
may, if it desires,  permit the transfer of the Preferred Shares,  the shares of
Common Stock issuable upon conversion of the Preferred  Shares (the  "Conversion
Shares"),  the Warrants or the shares of Common Stock  issuable upon exercise of
the Warrants (the "Warrant Shares") (collectively,  the "Securities") out of its
name only when its request for transfer is  accompanied by an opinion of counsel
reasonably  satisfactory  to the Company  that neither the sale nor the proposed
transfer  results in a violation of the Act or any  applicable  state "blue sky"
laws (collectively "Securities Laws").

          1.10 The  Subscriber  hereby  agrees that,  without the prior  written
consent of Commonwealth  Associates,  L.P. (the "Placement  Agent"), it will not
sell,  transfer or otherwise  dispose of the  Securities  for one year after the
final closing of the Offering and  thereafter  will not dispose of more than 25%
of the  Securities  on a cumulative  basis during each  subsequent 90 day period
thereafter  (the  "Lock-Up  Period");  provided,  however,  that if the  Company
undertakes any public offering within the first 12 months of the Lock-Up Period,
the Subscriber  will not sell,  transfer or otherwise  dispose of the Securities
for such  period of time after the closing of such  offering  (not to exceed six
months) as the managing  underwriter  or placement  agent may request in writing
and the Placement Agent may agree to. This restriction on transfer will apply to
any securities issued in exchange for the Securities in any merger.

          1.11 The  Subscriber  consents  to the  placement  of a legend  on any
certificate or other document  evidencing the Securities  stating that they have
not  been  registered  under  the Act and  setting  forth  or  referring  to the
restrictions on  transferability  and sale thereof,  and to the issuance of stop
transfer instructions with respect thereto.

          1.12  The  Subscriber   acknowledges   that  if  it  is  a  Registered
Representative  of an NASD  member  firm,  it must  give  such  firm the  notice
required  by the  NASD's  Rules  of Fair  Practice,  receipt  of  which  must be
acknowledged by such firm on the signature page hereof.


                                       3





          1.13 If the  undersigned  Subscriber  is a  partnership,  corporation,
trust or other  entity,  such  partnership,  corporation,  trust or other entity
further  represents  and warrants that: (i) it was not formed for the purpose of
investing in the Company;  (ii) it is authorized and otherwise duly qualified to
purchase and hold the Units; and (iii) that this Subscription Agreement has been
duly and validly  authorized,  executed and delivered and constitutes the legal,
binding and enforceable obligation of the undersigned.

          1.14 The Subscriber  hereby  represents that the address of Subscriber
furnished by him at the end of this Subscription  Agreement is the undersigned's
principal  residence if it is an individual or its principal business address if
it is a corporation or other entity.

          1.15 The Subscriber hereby represents that, except as set forth in the
Offering  Documents,  no  representations  or  warranties  have been made to the
Subscriber  by the Company or any agent,  employee or  affiliate of the Company,
including  the  Placement  Agent,  and in entering  into this  transaction,  the
Subscriber is not relying on any  information,  other than that contained in the
Offering  Documents  and  the  results  of  independent   investigation  by  the
Subscriber.

          1.16 The  Subscriber  acknowledges  that at such time as the  Reserved
Shares (as  defined  below) are  registered,  sales of such  securities  will be
subject to state  securities  laws,  including those of states which may require
any securities sold therein to be sold through a registered  broker-dealer or in
reliance upon an exemption from registration.

          1.17 The  Subscriber  acknowledges  that there is no minimum number of
Units that must be sold in the  Offering  and that the Maximum  Offering  may be
increased by up to 250 Units ($25,000,000) without notice to Subscribers.

          1.18 The  Subscriber  acknowledges  that  the  Placement  Agent  and a
committee to be  designated  by the  Placement  Agent whose  members hold in the
aggregate not less than 20% of the outstanding Preferred Shares or Warrants (the
"Committee")  may  consent to any  amendments,  modifications  or  waivers  with
respect to the Preferred  Shares or Warrants,  thereby binding the Subscriber to
any such amendment,  modification  or waiver;  provided,  however,  that no such
amendment,  modification or waiver which would decrease the number of Conversion
Shares  issuable upon the  conversion of the Preferred  Shares,  or increase the
Conversion  Price therefor (other than as a result of the waiver or modification
of any anti-dilution provisions) may be made without the approval of the holders
of at least 50% of the  outstanding  Preferred  Shares.  The  Subscriber  hereby
authorizes  the  Placement  Agent and the  Committee to act on the  Subscriber's
behalf and grants the Placement Agent and the Committee an irrevocable  proxy to
vote for any  amendment or waiver to the Articles of Amendment to the  Company's
Articles of  Incorporation to effect the foregoing.  The Subscriber  agrees that
neither the Placement  Agent nor any of its  directors,  officers,  employees or
agents nor the Committee or any of its members shall be liable to any Subscriber
for any  action  taken or  omitted  to be taken by it in  connection  therewith,
except for willful misconduct or gross negligence.  The Subscriber  acknowledges
that one or more members of the Committee  may be affiliated  with the Placement
Agent.  Any  transferee  of the Preferred  Shares or Warrants  shall agree to be
bound by this Section 1.18.

                                       4





          1.19 The  Subscriber  agrees that unless written  instructions  from a
majority  of the  holders  of  the  Preferred  Shares  is  received  instructing
otherwise,  the  Placement  Agent  will  act on  behalf  of the  holders  of the
Preferred Shares in appointing and removing directors representing the Preferred
Shares.

          1.20  The  Subscriber  acknowledges  that  the  Company  does not have
sufficient  authorized  shares  of  Common  Stock to  permit  conversion  of the
Preferred Shares or exercise of the Warrants. As a result, the Subscriber agrees
that it may not convert the Preferred Shares or exercise the Warrants until such
time the  Company has  sufficient  authorized  shares of Common  Stock to permit
conversion  or exercise of all the  Preferred  Shares and  Warrants and that the
inability to convert the Preferred  Shares or exercise the Warrants will deprive
the Subscriber of the value of the Preferred Shares or Warrants.

wish, jointly with any other indemnifying  party similarly  notified,  to assume
the defense  thereof,  with  counsel  satisfactory  to such  indemnified  party,
provided, however, if counsel for the indemnifying party concludes that a single
counsel cannot under applicable legal and ethical considerations, represent both
the  indemnifying  party and the indemnified  party,  the  indemnified  party or
parties have the right to select separate  counsel to participate in the defense
of such action on behalf of such indemnified party or parties. After notice from
the indemnifying  party to such  indemnified  party of its election so to assume
the  defense  thereof,  the  indemnifying  party  will  not be  liable  to  such
indemnified  party  pursuant to the  provisions of said paragraph (a) or (b) for
any legal or other expense  subsequently  incurred by such indemnified  party in
connection   with  the  defense   thereof   other  than   reasonable   costs  of
investigation,  unless (i) the indemnified  party shall have employed counsel in
accordance with the provisions of the preceding sentence,  (ii) the indemnifying
party shall not have employed counsel reasonably satisfactory to the indemnified
party to represent  the  indemnified  party  within a reasonable  time after the
notice of the commencement of the action or (iii) the indemnifying party has, in
its sole  discretion,  authorized the employment of counsel for the  indemnified
party at the expense of the indemnifying party.
