Service Area from time to time by giving written notice to Customer.

     2.8 Interruptions and Field Trials. The Service may be temporarily refused,

system capacity  limitations or equipment  maintenance,  repair,  modifications,
upgrades or  relocation.  AT&T will attempt to notify  Customer of scheduled and
unscheduled  network  outages that are expected to last more than four (4) hours
and that may affect the Service.  Customer will cooperate, at AT&T's expense, in

          5.1  Customer  will pay AT&T for Service  provided to Customer and its
     End Users in  accordance  with the  Service  Plan.  Unless the Service Plan

     may terminate this Agreement by providing AT&T with written notice at least
     fifteen  (15) days in  advance of such  termination.  Notwithstanding  the

          penalty upon written notice to Customer if the Federal  Communications
          Commission or any other  regulatory  agency or court  promulgates  any
          rule,   regulation,   judgment   or  order  that  (a)   prohibits   or
          substantially  impedes (in effect or Application) AT&T from fulfilling
          its  obligations  hereunder,  (b) prohibits or  substantially  impedes
          non-AT&T Service  providers from providing  Service,  or (c) adversely

          acceptable to it. AT&T will notify Customer promptly  following AT&T's
          determination that an event permitting  termination under this Section
          has occurred.

          requirements set forth in Exhibit C, Company may provide Customer with
          ninety (90) days written  notice  either 1) that Customer is no longer
          eligible to receive Service under this  Agreement,  or 2) that Company
          will modify the Service  Plan in  accordance  with  Customer's  actual
          usage.  If Customer is unable,  during the sixty (60) day period after
          Company's notice is sent, to satisfy the eligibility criteria, Company
          and Customer will  renegotiate the Service Plan  Requirements.  If the
          parties fail to reach a mutually  acceptable  agreement  regarding the
          Service Plan within the following thirty (30) day period,  Company may
          either,  immediately or upon notice to Customer, 1) modify the Service
          Plan, or 2) terminate this Agreement  without further  notice,  in its
          sole discretion.

     other  provisions of this  Agreement  that may reasonably be interpreted or
     construed as surviving  termination)  will survive the  termination of this
     Agreement.

     any  reason,  all  amounts  owing to AT&T  hereunder  will  become  due and

     modification  or  waiver  of any  provision  of this  Agreement  must be in
     writing and signed by authorized representatives of the parties.

     19.2 Severability.  If any provision, or portion thereof, of this Agreement
     is invalid or unenforceable  under applicable statute or rule of law, it is
     only to that extent to be deemed omitted, and such  unenforceability  shall
     not affect any other provision of this Agreement,  but this Agreement shall
     then be construed as if such  unenforceable  provision  or  provisions  had

     19.4 Waiver.  The failure by Customer or BANM at any time to enforce any of
     the provisions of this Agreement or any right with respect thereto, will in

     way to affect the  validity of this  Agreement.  The exercise by a party of
     any  rights  under  the terms or  provisions  of this  Agreement  shall not
     preclude or prejudice  the  exercising  thereafter of the same or any other

     agreement, entrenet becomes involved in any capacity in any action or legal
     proceeding,  the Company agrees to reimburse  entrenet,  its affiliates and
     their  respective  directors,  officers,  employees,   representatives  and
     controlling  persons (each an "Indemnified  Person')  promptly upon request
     for all expenses (including without  limitation,  fees and disbursements of
     legal counsel and the cost of  investigation  and  preparation) as they are
     incurred.  In the event a  determination  is made to the  effect  set forth
     below holding that entrenet is not entitled to  indemnification  hereunder,
     entrenet  shall promptly  refund to the Company all amounts  advanced under
     this  Section in respect of  reimbursement  of  expenses.  The Company also
     agrees to indemnify and hold each  Indemnified  Person harmless against all
     losses,  claims  damages or  liabilities,  joint or several  (collectively,
     "Damages"), to which such Indemnified Person may become subject

          (i)  arising  out of or based  upon any  untrue  statement  or alleged
          untrue  statement  of  a  material  fact  contained  in  any  offering
          materials or any other written or oral  communication  provided to any
          investor of  securities of the Company or arising out of or based upon
          the  omission  or alleged  omission  to state in any such  document or
          communication  a  material  fact  required  to be  stated  therein  or
          necessary  in order to make the  statements  therein,  in light of the
          circumstances under which they were made, not misleading; or

          (ii) in connection  with the services or matters which arc the subject
          of this agreement, provided that the Company shall not be liable under
          the foregoing indemnity in respect of any Damages to the extent that a
          court having  jurisdiction  shall have  determined by a final judgment
          (not subject to further  appeal) that such damages  resulted  directly
          and  primarily  from the gross  negligence  or willful  misconduct  of
          entrenet or any other Indemnified Person. The Company also agrees that
          no  Indemnified  Person shall have any liability to the Company for or
          in connection  with this  engagement,  except for any liability  which

          misconduct of the Indemnified Person.
     

(b)  The  Company  and  entrenet  agree  that  if,  for  any  reason,   any
     indemnification  sought  pursuant  to this  Section  is  unavailable  or is
     insufficient to hold any Indemnified Person harmless,  then, whether or not
     entrenet  is the  person  entitled  to  indemnification,  the  Company  and
     entrenet shall each contribute to amounts paid or payable in respect of the
     Damages for which such  indemnification  is unavailable or  insufficient in
     such  proportion as if appropriate to reflect 

          (i)  the  relative  benefits  to the  Company,  on the one  hand.  and
          entrenet, on the other and

          (ii) their relative  fault, in connection with the matters as to which
          such Damages relate, as well as any relevant equitable considerations;
          provided  that in no event  shall  the  amount  to be  contributed  by
          entrenet  exceed  the amount of fees  actually  received  by  entrenet
          hereunder   (excluding   any   amounts   received  by  entrenet  as  a
          reimbursement of expenses).  The Company and entrenet agree to consult
          in advance  with one another with respect to the terms of any proposed
          waiver, release or settlement of any claim

                             (Address, City, State)

herein  called  "Customer",  hereby agrees with GTE Leasing  Corporation  herein
called GTELC, of 19845 U.S. Hwy. 31 N., Westfield, IN 46024-as follows:

    1.   Concurrently   herewith,   GTELC  lent  Customer  and  Customer  hereby
         acknowledges   receipt  of  $  Eighty   Thousand  and  no/100   Dollars
         ($80,000.00)  evidenced  by  Promissory  Note  of even  date  herewith,
         executes by Customer  payable to the order of GTELC,  with  interest as
         provided therein (principal and accrued interest are herein referred to
         as "Indebtedness").

    2.   As security  for the payment by  Customer of the  Indebtedness  and all
         other indebtedness now or hereafter owing by Customer to GTELC, and the
         performance  by Customer of the  covenants,  warranties  and agreements
         contained herein,  and any other agreements between GTELC and Customer,
         Customer hereby grants, sells, assigns,  conveys,  warrants,  mortgages
         and  confirms  to GTELC and gives and agrees  that GTELC does and shall
         have a security  interest under the Uniform  Commercial Code, in all of
         the following described personal property (herein called "Collateral"):

                            DESCRIPTION OF COLLATERAL

200 ea. Tranz Enabler - Wireless CDPD Transmission Devices per attached Schedule
- --------------------------------------------------------------------------------

         The right to receive  proceeds  from the  contract by and between  Nova
         Information Systems and Maker dated February 7,1997

      3.   Customer  warrants that it is or will be the owner of Collateral free
           and  clear of any  liens or  encumbrances,  except  for the  security
           interest  provided  for herein;  and will keep and  maintain the same
           free and  clear of all  encumbrances,  charges  and  liens  except as
           herein provided.

      4.   Collateral  will not be moved  from the state  where it is  currently
           located,  nor will it be sold or otherwise  disposed of without prior
           written consent of GTELC.

      5.  Customer  will keep and maintain  Collateral  in good order and repair
          and working condition at all times.

      6.  At  Customer's  own  cost  and  expense,  it will  have  and  maintain
          insurance at all times against hazards,  with companies in amounts and
          in form acceptable to GTELC with insurance  policies  endorsed to make
          the same payable  first to GTELC,  as its interest may appear.  In the
          event of any loss  thereunder,  the carriers  owned therein hereby are
          directed by Customer to make such payment for loss to GTELC and not to
          Customer and GTELC jointly.  If any insurance losses be paid by check,
          draft or other instrument payable to Customer and GTELC jointly, GTELC
          may endorse the name of Customer  thereon and do such other  things as
          it may deem  desirable  in order to reduce the same to cash.  All loss
          recoveries  received by GTELC upon any such  insurance  may be applied
          and credited by GTELC at its discretion, to the indebtedness or to any
          other amounts owing from Customer to GTELC.

7.        If  Customer  fails  to  keep   Collateral   free  and  clear  of  all
          encumbrances,  liens and charges, except as herein provided, or to pay
          tax or public  charges  thereon,  or to keep the same in good order or
          repair,  or fully  insured  as herein  required,  then  GTELC,  at its
          discretion,  may discharge such encumbrances,  liens or other charges,
          or pay such taxes or other  public  charges,  or procure and  maintain
          such insurance or make such repairs as may deem advisable. All sums of
          money  thus  expended,  and all  other  monies  paid by  GTELC  at its
          discretion,  to  protect  its  interest  in the  Collateral  shall  be
          repayable by Customer to GTELC on demand, and if not so repaid,  shall
          be added to the  Indebtedness,  bear interest,  and be secured in like
          manner as the Indebtedness.

8.        Customer  confirms  that  the  security  interest  of  GTELC  in other
          equipment,  chattels and personal property of Customer under any other
          agreements  between  GTELC and Customer is also security of Customer's
          obligations hereunder.

9.        None of the terms or conditions  herein or any agreements or contracts
          between  Customer and GTELC are in  violation of any  provision of the
          Certificate of  Incorporation or By-Laws of Customer or any agreements
          Customer may have with any third party; and the execution and delivery
          hereof, and of other agreements or writings with or to GTELC have been
          duly authorized by appropriate corporate action.  Customer will at all
          times  comply  with all  acts,  laws,  rules  and  regulations  of any
          federal, state or public authorities to which Customer is subject.

10.       Upon  Customer's  default in the payment of any  principal or interest
          under  the  Note,  when  due,  or  default  or  branch  of  any of the
          provisions hereof, or in the payment performance of any obligations of
          Customer to GTELC,  or it Customer  becomes  insolvent,  ceases  doing
          balances as a going concern, or commits an act of bankruptcy,  or if a
          petition  under the  Bankruptcy  Code or any amendment  thereof or any
          state  insolvency law be filled by Customer or against Customer and be
          not dismissed within thirty (30) days, or an attachment or tax lien be
          filed against to the  satisfaction  of GTELC,  then as the election of
          GTELC, the entire unpaid indebtedness shall immediately become due and
          payable  without  notice,  and if not paid,  GTELC at any time then or
          thereafter,  in its  discretion,  may lawfully enter any of Customer's
          premises  or other  premises  on which the  Collateral  is located and
          lawfully  remove  the  Collateral  to such  place  as  GTELC  may deem
          advisable,  or  require  Customer  to make any or all such  Collateral
          available at such place as GTELC may direct,  and,  upon five (5) days
          written notice to Customer, sell the Collateral,  or any part thereof,
          at public  auction,  in one or more sales, at such price or prices and
          upon such terms  either for cash,  credit or future  delivery as GTELC
          may elect,  and at any such public sale or sales GTELC may bid for and
          become the purchaser of any or all such  Collateral,  and/or upon five
          (5) days  written  notice to  Customer of the date and details of such
          sale or sales,  sell the  Collateral or any part  thereof,  at private
          sale or sales,  at any time or place,  in one or more  sales,  at such
          price for  prices,  and upon such  terms,  either for cash,  credit or
          future  delivery,  as GTELC may elect,  and/or  foreclose its security
          interest in the  Collateral  in any way permitted by law. The proceeds
          of such  sales may be  applied  by GTELC,  at its  discretion,  to the
          payment  of  Customer's  obligations  to  GTELC,  including  interest,
          attorneys'  reasonable  fees  and all  reasonable  cost  and  expenses
          incurred by GTELC in  connection  therewith.  In  connection  with the
          notices given of such sales,  it is agreed that in all instances  five
          (5) days written  notice is reasonable  notice.  GTELC may enforce its
          security  interest  hereunder either  alternately or concurrently with
          its rights  under other  agreements  between it and Customer and shall
          have  the  full  right  to  realize  upon  all  available  collateral,
          collecting  on  the  same  or  instituting  procedures  in  connection
          therewith,  until  GTELC has  received  payment in full of all amounts
          owing to it  under  any of its  agreements  with  Customer,  including
          principal,  interest,  costs and expenses. Any surplus remaining after
          payment in full of all Indebtedness of Customer to GTELC shall be paid
          by GTELC to  Customer  along with the  reassignment  of any  remaining
          Collateral.

11.       Any delay on the part of GTELC in exercising  any power,  privilege or
          right hereunder or under any instrument  executed by Customer to GTELC
          in connection  herewith  shall not operate as a waiver  thereof and no
          single or partial  exercise  of any power,  privilege  or right  shall
          preclude  other or further  exercise  thereof,  or the exercise of any
          other power, privilege or right. The waiver by GTELC of any default by
          Customer shall not constitute a waiver of any subsequent defaults, but
          shall be  restricted  to the  default so  waived.  If any part of this
          Agreement shall be contrary to any law which GTELC might seek to apply
          or enforce or should  otherwise be defective,  the other provisions of
          this Agreement  shall not be affected  thereby,  but shall continue in
          full  force and  effect.  All  rights,  remedies  and  powers of GTELC
          hereunder are  irrevocable  and  cumulative,  and not  alternative  or
          exclusive, and shall be in addition to all rights, remedies and powers
          given  hereunder  or in or by any  other  instruments  or any laws now
          existing or hereafter enacted.

12.       Customer  shall pay all  out-of-pocket  expenses  and all costs of any
          nature  whatsoever  incurred by GTELC in connection with the making of
          this  loan,  including,  but not  limited  to,  all  filing  fees  and
          recording costs, stamp taxes and attorneys' fees actually incurred.
<PAGE>
13.       Customer including any guarantor hereunder, hereby waives presentment,
          demand,  protest,  notice of protest,  and  non-payment  or  dishonor,
          notice of the sale of any  collateral  security  and all  benefits  of
          valuation,  appraisement,  and all  exemption  laws  now in  force  or
          hereafter passed, including stay of execution and condemnation.

14.       This  Agreement  shall  apply and inure to the benefit of and bind the
          successors and assigns of Customer and GTELC, and the terms "Customer"
          and "GTELC" include and mean, respectively, the successors and assigns
          of Customer and GTELC.

IN WITNESS  WHEREOF,  Customer has caused this  Agreement to be duly executed on
the day and year first above written.

This CDPD Service and  Equipment  Agreement  (this  "Agreement")  is between GTE
Mobile  Communications  Service  Corporation  on its behalf and on behalf of GTE
Mobilnet  Incorporated and Contel Cellular Inc. and their respective  affiliates
and  partnership  interests  (collectively  referred  to as  "GTEMC")  and  U.S.
Wireless Data Inc.  ("Customer")  for the provision of Cellular  Digital  Packet
Data Services  ("CDPD  Services") in the those markets (the "Markets") set forth
on Exhibit A hereto,  as modified from time to time by GTEMC.  The parties agree
as follows:


1.       Term. The term of this Agreement  shall be for an initial period of two
         (2) years,  which shall commence as set forth in paragraph 13. Upon the
         expiration of the initial period,  this Agreement  shall  automatically
         and  perpetually  renew for  additional  periods of two (2) years each,
         unless  canceled by either party upon written notice given to the other
         party at least ninety (90) days prior to the  expiration of the initial
         term and any renewal term then in effect.

2.       Service  Pricing.  Pricing for CDPD Services will be in accordance with
         the Pricing Plan which is attached  hereto and  incorporated  herein as
         Exhibit B. The parties agree that GTEMC will be the exclusive  provider
         of CDPD  Services in all GTEMC  markets  listed in Exhibit A.  Customer
         optionally  may purchase  GTEMC's CDPD services in markets not owned by
         GTEMC  using the same  pricing  shown in Exhibit B. It is  specifically
         acknowledged  and agreed by the parties  that GTEMC cannot and will not
         attempt to set,  influence or determine the service rates or pricing of
         other carriers.

3.       Minimum  Requirement.  In consideration  for the CDPD Services provided
         herein, Customer is required to meet the revenue commitments as defined
         in Exhibit B.

4.       Specification  of Service.  GTEMC or an affiliate  company will provide
         and procure for Customer CDPD Services for Customers application in the
         Markets.  The areas  effectively  served may be subject to transmission
         limitations  caused by  atmospheric  and other  natural  or  artificial
         conditions,  including the type and  condition of Customers  equipment.
         GTEMC assumes no  responsibility to Customer or its CDPD Services users
         for marginal  transmissions arising from or related to interruptions or
         limitations  caused by any natural,  atmospheric or artificial  causes.
         The names  assigned to GTEMC's CDPD  Services,  "Coverage"  and "Local,
         State, Regional and National" are representative terms that do not

<PAGE>
         imply or denote that actual CDPD Services  coverage is coterminous with
         these respective geographical areas. In any geographical area there may
         be sections in which CDPD Services coverage does not exist.

5.       NEls.  In connection  with its  provision of CDPD  Services  hereunder,
         GTEMC shall provide Customer with an NEI for each user device. Customer
         shall acquire no  proprietary  interest in any such NEI  designated for
         its use,  and  GTEMC  reserves  the  right to  change  such  NEls or to
         re-assign such NEls to other customers.

6.       Equipment.  GTEMC may,  but shall not be obligated  to, make  available
         CDPD  equipment  (the  "Equipment")  for purchase by Customer.  In such
         event,  GTEMC will provide to Customer the terms and conditions for the
         purchase of such Equipment.

7.       Data  Services  Reporting  and  Billing.  For CDPD  Services  charges,
         payment terms are as follows:

Payment for CDPD Services is due within thirty (30) days of the date of invoice.
Overdue  balances shall accrue a late payment fee equal to the lesser of one and
one-half  percent  (1.5%)  per month on any  amount  not paid  when due,  or the
highest  amount  allowable by applicable  state law or tariff.  The fee shall be
paid every month on all outstanding overdue balances,  and shall be prorated for
each day  that  the  payment  is  overdue.  Such  late  payment  fee will not be
compounded monthly. If timely payment is not received in full, GTEMC may, at its
sole option and without limiting any other remedy available under law or in this
Agreement,  disconnect  CDPD  Services,  subject  to a  reconnection  charge for
service  restoration.  Customer must meet GTEMC's established credit criteria in
order to receive CDPD Services hereunder.

8.       Taxes. Prices are exclusive of all federal,  state,  municipal or other
         government, excise, sales, use, occupational, or like taxes. The amount
         of any present or future tax applicable to the sale of the Equipment or
         CDPD Services  shall be paid by the Customer or, in lieu  thereof,  the
         Customer   shall  furnish  GTEMC  with  a   tax-exemption   certificate
         acceptable to the appropriate tax authorities.

9.        Limitation of  Liability.  GTEMC shall not be liable to Customer or to
          CDPD Services users for  interruptions  caused by failure of equipment
          or CDPD Services,  failure of communications,  power outages, or other
          interruptions not within the complete control of GTEMC. There shall be
          no  credits,  reductions,  or  setoff  against  the  charges  for CDPD
          Services for downtime or  interruption  of CDPD  Services  unless such
          CDPD Services interruption exceeds twenty-four (24) hours in duration.
          GTEMC shall  provide  Customer  with a credit  equal to one  thirtieth
          (1/30) of the  recurring  monthly  charge for CDPD  Services  for each
          twenty-four  (24) hour period from the time of notice of  interruption
          until  CDPD  Services  restoration,   provided  that  Customer  timely
          notifies GTEMC of the CDPD Services interruptions.

          GTEMC  terminate this  Agreement,  the Customer shall be entitled to a
          refund of any  payment  made in  advance of the  actual  provision  of
          services.

          F. Non-assignment.  Neither party may assign this Agreement, except to
          an  affiliate  company or upon  GTEMC's sale of any market as provided
          hereinafter,  without  the other's  prior  written  consent,  and such
          consent shall not be unreasonably  withheld.  However, in the event of
          the sale of any market or the  cessation of  ownership,  management or
          control by GTEMC,  GTEMC may seek the  assignment of this Agreement to
          its successor without the requirement of Customers  consent.  However,
          nothing  contained  herein  shall be  construed  as an  obligation  or
          requirement  by GTEMC to obtain any such  assignment or as a condition
          of sale of any market or customer base.

          G.  Non-waiver.  Failure of either party to this  Agreement to enforce
          any right  shall not  constitute  a waiver of such  right or any other
          right,  whether  of a  similar  or  dissimilar  nature,  and shall not
          prohibit the exercise of the same right at a future date.

          H.  Severability.  In the event that any  provision of this  Agreement
          shall be found to be void or unenforceable,  such finding shall not be
          construed to render any other provision of this Agreement  either void
          or  unenforceable,  and all  other  provisions  which are  invalid  or
          unenforceable shall not substantially affect the rights or obligations
          granted to or undertaken by either party.

          I.  Headings.  The headings of the  provisions  of this  Agreement are
          inserted for convenience only and shall not constitute a part hereof.

          J. Law Governing. This Agreement is entered into under the laws of the
          State of Georgia and shall be construed thereunder.

11. Notice.  Any notice to be given hereunder by either party to the other shall
be in writing and shall be deemed given when sent by postage  prepaid  certified
or registered United States mail.

         b)     A GTE CDPD NEI address; and

         c) A USWD provided credit/debit card transaction payment service with a

          a) The  GTE  sales  representatives  will  utilize  appropriate  sales

          to filled out. The GTE sales  representative will submit the completed

        representing  shares of the Company's  Common Stock as and when required
        hereunder,  the  Company  shall,  unless  the  time for  performance  is
        extended in writing by the  Consultant,  pay to  Consultant  and Prag in
        lieu of delivery of the shares of Common Stock with respect to which the
        Company is in  default,  an amount per  undelivered  share  equal to the
        average  closing  asked price per share of Common  Stock during the five
        trading  days  ending  with the day on which the  Company  was  required
        hereunder to deliver but failed to deliver such shares of Common Stock.

4.2     Consultant  and  Prag   (hereinafter   referred  to  as   "Consultants")
        acknowledge  that the shares of Common  Stock to be issued  pursuant  to
        this Agreement  (collectively,  the "Shares")  have not been  registered
        under  the  Securities  Act of 1933,  and  accordingly  are  "restricted
        securities"  within  the  meaning of Rule 144 of the Act.  As such,  the
        Shares may not be resold or transferred  unless the Company has received
        an opinion of counsel  reasonably  satisfactory to the Company that such
        resale or transfer is exempt from the registration  requirements of that
        Act.

4.3     In connection with the acquisition of Shares hereunder,  the Consultants
        represent and warrant to the Company as follows:

         (a) Consultants acknowledge that the Consultants have been afforded the
         opportunity  to  ask  questions  of  and  receive   answers  from  duly
         authorized officers or other  representatives of the Company concerning
         an investment in the Shares,  and any additional  information which the
         Consultants have requested.  

          (b) Consultants'  investment in restricted securities is reasonable in
          relation to the Consultants' net worth, which is in excess of ten (10)
          times the Consultants' cost basis in the Shares.  Consultants have had
          experience  in   investments   in  restricted   and  publicly   traded
          securities,  and  Consultants  have had  experience in  investments in
          speculative securities and other investments which involve the risk of
          loss of investment. Consultants acknowledges that an investment in the
          Shares is speculative and involves the risk of loss.  Consultants have
          the  requisite  knowledge to assess the  relative  merits and risks of
          this investment  without the necessity of relying upon other advisors,
          and Consultants  can afford the risk of loss of his entire  investment
          in the Shares.  Consultants are (i) accredited investors, as that term
          is defined in Regulation D  promulgated  under the  Securities  Act of
          1933,  and (ii) a purchaser  described in Section 25102 (f) (2) of the
          California Corporate Securities Law of 1968, as amended.

         (c)  Consultants  are  acquiring  the Shares for the  Consultants'  own
         account for long-term  investment  and not with a view toward resale or
         distribution  thereof except in accordance with  applicable  securities
         laws.


5.  Financing  "Finder's  Fee".  It is understood  that in the event  Consultant
introduces  Company,  or its  nominees,  to a lender  or equity  purchaser,  not
already having a preexisting  relationship with the Company,  with whom Company,
or its nominees, ultimately finances or causes the completion of such financing,
Company agrees to compensate  Consultant for such services with a "finder's fee"
in the amount of 2.5% of total gross funding provided by such

                                       4.
<PAGE>
tender or equity  purchaser,  such fee to be  payable  in cash.  This will be in
addition to any fees payable by Company to any other intermediary, if any, which
shall be per  separate  agreements  negotiated  between  Company  and such other
intermediary.

5,1        It is  further  understood  that  Company,  and  not  Consultant,  is
           responsible  to perform any and all due  diligence  on such lender or
           equity purchaser introduced to it by Consultant under this Agreement,
           prior  to  Company  receiving  funds.  However,  Consultant  will not
           introduce any parties to Company about which Consultant has any prior
           knowledge of questionable, unethical or illicit activities.

5.2       Company agrees that said  compensation to Consultant shall be paid in
           full  at  the  time  said   financing  is  closed.   Moreover,   said
           compensation,  will be a condition precedent to the closing,, of such
           funding or financing  and Company shall execute any and all documents
           necessary to effect said compensation.

5.3        As further  consideration  to Consultant,  Company,  or its nominees,
           agrees to pay with  respect to any  financing  provided  directly  or
           indirectly to the Company by any lender or equity  purchaser  covered
           by this  Section 5.  during the period of five years from the date of
           this Agreement, a fee to Consultant equal to that outlined in Section
           "5" herein.

5.4        Consultant  will  notify  Company  of   introductions  it  makes  for
           potential   sources  of   financing  in  a  timely   manner   (within
           approximately 3 days of introduction)  via facsimile memo. If Company
           has a  preexisting  relationship  with such nominee and believes such
           party  should be excluded  from this  Agreement,  then  Company  will
           notify  Consultant  immediately  of such  circumstance  via facsimile
           memo.

6.  Expenses.  Consultant  agrees to pay for all its expenses  (phone,  mailing,
labor, etc.), other than extraordinary items (travel required by/or specifically
requested  by the Company,  luncheons  or dinners to large groups of  investment
professionals,   mass  faxing  to  a  sizable   percentage   of  the   Company's
constituents,  investor conference calls, print  advertisements in publications,
etc.)  approved  by  the  Company  prior  to its  incurring  an  obligation  for
reimbursement.

7.   Indemnification.   The  Company  warrants  and  represents  that  all  oral
communications,  written  documents or materials  furnished to Consultant by the
Company  with  respect  to  financial  affairs,  operations,  profitability  and
strategic  planning of the Company are accurate and Consultant may rely upon the
accuracy thereof without  independent  investigation.  The Company will protect,
indemnify  and  hold  harmless  Consultant  against  any  claims  or  litigation
including  any  damages,  liability,  cost  and  reasonable  attorney's  fees as
incurred with respect  thereto  resulting  from  Consultant's  communication  or
dissemination of any said information,  documents or materials not designated by
the Company to the Consultant as "confidential" or "Company private",  excluding
any such claims or  litigation  resulting  from  Consultant's  communication  or
dissemination  of information not provided or authorized by the Company.  To the
extent feasible,  the Company agrees to make Consultant an additional insured on
any and all commercial  liability and directors and officers liability insurance
policies  and to provide  Consultant  with  current  Certificates  of  Insurance
reflecting the same.

U.S. Wireless Data, Inc.
1123 Western Avenue
Mill Valley, California 94914
Ladies and Gentlemen:

     1.  General.   U.S.  Wireless  Data,  Inc.,  a  Colorado  corporation  (the
"Company"),  is offering,  pursuant to Regulation D ("Regulation D") promulgated
under  the-Securities  Act of  1933,  as  amended  (the  "Securities  Act"),  an
aggregate  of up to four (4)  units  (the  "Units"),  each  consisting  of eight
hundred  seventy-five  thousand  (875,000)  share of the Company's  Common Stock
("Common   Stock"),   and  warrants   ("Warrants")   expiring  August  1,  2002,
substantially  in the form of warrant  attached hereto as Exhibit A, to purchase
up to four  hundred  thousand  (400,000)  shares of Common  Stock at an exercise
price of One Cent ($0.01) per share.  The Units are being  offered at a price of
One Hundred Twenty-Five Thousand Dollars ($125,000) per Unit.

     2.  Subscription.  The  undersigned  subscriber  (the  "Purchaser")  hereby
irrevocably  subscribes  for and agrees to  purchase  three (3)  Unit(s)  for an
aggregate  purchase  price  of  Three-Hundred   Seventy-Five   Thousand  Dollars
($375.000.00.)  (the "Subscription  Price") Funds representing the Subscription
Price  shall be paid by the  Purchaser  to the Company  against  issuance of the
securities constituting the Units.

     3.  Representations.  Warranties and Covenants of Purchaser.  The Purchaser
hereby  acknowledges,  represents  and warrants to and covenants and agrees with
the company that:

         (a) Purchaser is an  "accredited  investor",  as defined in Rule 501 of
  Regulation D promulgated under the Securities Act.  Purchaser is acquiring the
  Units for  Purchaser's  own  account and not for the account or benefit of any
  other  person.  The  Units,  and the shares of Common  Stock and the  Warrants
  constituting  the Units and the shares of Common  Stock for which the Warrants
  may be  exercised  (collectively,  the  "Securities")  will be acquired by the
  Subscriber  in  good  faith  for  investment  and  not  with  a  view  to  the
  distribution  thereof.  The  Purchaser  does not  presently  intend to sell or
  otherwise  dispose of all or any part of the Securities upon the occurrence or
  nonoccurrence of any predetermined event;

<PAGE>
(b) The Purchaser is willing and able to bear the economic risk of an investment
  in the Units in an amount equal to the amount the Purchaser has  subscribed to
  purchase,  and the Purchaser has adequate means of providing for current needs
  and reasonably anticipated contingencies and has no need for liquidity in such
  investment.  In making these statements,  the Purchaser has taken into account
  (i) that Purchaser may have to hold the  Securities  for an indefinite  period
  and (ii) that the Purchaser  could  experience a complete loss of  Purchaser's
  investment in the Units;

(c)      Purchaser:

                    (i) has been  provided with copies of all of the reports and
           other documents filed by the Company with the Securities and Exchange
           Commission  pursuant  to the  Securities  Exchange  Act of  1934,  as
           amended (the "Exchange Act"), during the past twelve months;

                    (ii) has been given the  opportunity to ask questions of the
           Company and its  management  concerning the Company,  the Units,  the
           terms and conditions of the offering and other matters  pertaining to
           this  investment,  in order for  Purchaser to evaluate the merits and
           risks of an  investment  in the Units,  and  Purchaser  has  received
           satisfactory responses to all such questions; and

                    (iii)  acknowledges  that  the  Units  were not  offered  to
           Purchaser by way of any general solicitation or advertising and at no
           time was the  Purchaser  presented  with or solicited by means of any
           leaflet,  public promotional meeting,  circular,  radio or television
           advertisement, newspaper or magazine article;

           (d) Since the  offer  and sale of the Units and of the  Common  Stock
  issuable  upon  exercise of the Warrants  have not been  registered  under the
  Securities Act in reliance upon Regulation D among other provisions, Purchaser
  will only offer or resell the Securities in compliance  with the provisions of
  all applicable securities laws and regulations. Purchaser will offer or resell
  the Securities only if the Securities are registered  under the Securities Act
  or an exemption  from such  registration,  including  without  limitation  the
  exemption afforded under Rule 144, is available.  Unless such registration has
  been effected or such an exemption is available,  the Company shall not permit
  the transfer of the Securities.

                    The  Purchaser  understands  and agrees that the company may
  take such reasonable steps as it deems  appropriate to ensure  compliance with
  the offer, resale and other restrictions on transfer and conversion  contained
  in this Subscription Agreement
                                        2
<PAGE>
(the  "Agreement")  or  arising  under  applicable  securities  laws,  including
instituting  "stop  transfer"  instructions  with respect to the  Securities and
endorsing   restrictive  legends,   such  as  the  following,   on  certificates
representing the Securities:

          " The  securities  represented  by  this  Certificate  have  not  been
          registered   under  the  Securities  Act  of  1933,  as  amended  (the
          "Securities  Act")  and are  "restricted  securities"  as that term is
          defined in Rule 144 under the  Securities  Act. The securities may not
          be offered for sale, sold or otherwise  transferred except pursuant to
          an  effective  registration  statement  under  the  Securities  Act or
          pursuant to an exemption from registration under the Securities Act."

         (e) The execution  and delivery of this  Agreement by Purchaser and the
consummation  by Purchaser of the  transactions  contemplated  by this Agreement
will not violate any statute or law or any judgment,  decree, order,  regulation
or rule of any court or  governmental  authority by which Purchaser is bound or,
if  Purchaser  is other  than a natural  person,  the  charter,  bylaws or other
instruments under, which Purchaser is formed and its activities are governed.

     4.  Representations  and  Warranties  of The  Company.  The Company  hereby
represents and warrants to the Purchaser as follows:

          (a) The Company has filed all reports and other materials  required by
     the Exchange Act to be filed with the  Securities  and Exchange  Commission
     during  the past 12  months.  All such  reports  and  materials  have  been
     complete  and  accurate  and have  complied  with the  requirements  of the
     Exchange  Act in all  material  respects  and did not  contain  any  untrue
     statement of a material fact or omit to state any material  fact  necessary
     in order to make the statements  therein, in the light of the circumstances
     existing at such dates, not misleading.

          (b) The  Company is, and at the time of the  issuance  and sale of the
     Units will be, a corporation  duly organized,  validly existing and in good
     standing  under the laws of  Colorado.  The Company has, and at the Closing
     Date will have,  full power and  authority  to conduct  all the  activities
     conducted  by it, to own or lease all the assets  owned or leased by it and
     to  conduct  its  business  as  described  in the  reports  referred  to in
     paragraph (a) above.

          (c) The Company has full  corporate  power and authority to enter into
     this  Agreement.  This  Agreement  has been duly  authorized,  executed and
     delivered by the Company and  constitutes a valid and binding  agreement of
     the Company and is enforceable  against the Company in accordance  with the
     terms hereof.
                                        3
<PAGE>
          (d) The  Securities  to be  delivered  at the  Closing  have been duly
     authorized  and when  issued  for  consideration  as  contemplated  in this
     Agreement  will  be  validly  issued  and   outstanding,   fully  paid  and
     non-assessable.

     5.  Covenants  of  Company.  The  Company  covenants  and  agrees  with the
Purchaser as follows:

          (a) Following an exercise of the Warrants,  the Company will cause its
     transfer agent promptly,  at the Company's  expense,  to issue certificates
     evidencing  the  shares  of  Common  Stock  being  purchased  through  such
     exercise.  In the event  the  Company  for any  reason,  including  without
     limitation the  unavailability of authorized but unissued shares,  does not
     cause the prompt issuance of such certificates,  the Company shall upon the
     written demand of the Purchaser  redeem from the Purchaser the Warrants the
     Purchaser attempted to exercise or otherwise pay to the Purchaser by way of
     liquidated damages for such breach against cancellation of such Warrants an
     amount per warrant equal to the remainder calculated by subtracting (i) the
     Warrant  exercise price from (ii) average  closing asked price per share of
     Common  Stock during the five trading days ending with the day on which the
     Purchaser exercises or attempts to exercise the Warrant.

<PAGE>
          5 .      Stock as Investment.
          -----------------------------

         By  accepting  this  Warrant,  the Warrant  Holder  agrees that it is

to be issued upon the election to purchase  shares  Lender this Warrant have not
been  registered at the time of proposed  issuance  under the  Securities Act of
1933,  as amended (the "Securities Act"), the Warrant Holder shall deliver to   
the Company at the time of such issuance a written  representation  that warrant
holder is acquiring such Shares in good faith for investment purposes only and
not for resale or  distribution.  Company may place a "stop transfer" order with
respect  to such  Shares  with its  transfer  agent  and  place an  appropriate
restrictive legend on the stock certificate(s)  evidencing such Shares, in order
to prevent  transfers unless such Shares are registered under the Securities Act
or an exemption  from the  registration  requirements  of the  Securities Act is
applicable.

         6.      Conditions to Issuance of Shares,
         -----------------------------------------

         The Company shall issue and deliver  certificates  for Shares purchased
upon the exercise of any portion of the Warrant granted hereunder.

         7.       Registration Rights.
         -----------------------------

         (a) If, at any time  during the  exercise  period  hereof and the three
years  following  any  exercise  hereunder,  the  Company  proposes  to  file  a
registration  statement  with  respect to any class of  securities  (other  than
pursuant to a registration  statement on Forms S-4 or S-8 or any successor form)
under the  Securities  Act, the Company shall notify the Warrant Holder at least
twenty  (20) days prior to the filing of such  registration  statement  and will
offer to include in such registration statement all or any portion of the shares
of Common  Stock then owned by the Warrant  Holder or which the  Warrant  Holder
then has the right to acquire,  weather  pursuant to this  Warrant or  otherwise
(collectively the "Shares").  In a written notice to be delivered to the Company
within  twenty  (20) days after  receipt of any such notice  from  Company,  the
Warrant  Holder  shall state the number of Shares that it wishes to register for
resale and distribution publicly under the proposed registration statement.  The
Company will use its best efforts, through its officers, directors, auditors and
counsel in all matters  necessary  or  advisable,  to file at least one (1) such
registration  statement  by May 15,  1998.  The  Company  will also use its best
efforts,  through its officers,  directors,  auditors and counsel in all matters
necessary or advisable, to include within the coverage of each such registration
statement  (except as  hereinafter  provided) the Shares that Warrant Holder has
advised  company  that  Warrant  Holder  wishes  to  register  pursuant  to such
registration  statement  for resale and  distribution,  to  prosecute  each such
registration   statement   diligently  to  effectiveness,   and  to  cause  such
registration  statement to become  effective as promptly as  practicable In that
regard,  the company makes no representation or warranties as to its ability to
have any registration statement declared effective.

                                                                    
         All  registrations  requested  pursuant  to  this  Paragraph  7 (a) are
referred to herein as  "Piggyback  Registrations."  In the event the Company is
advised  by the  staff  of the  SEC,  NASDAQ  or any  self-regulatory  or  state
securities  agency that the  inclusion of the Shares will  prevent,  preclude or
materially delay the effectiveness of a registration statement filed, the
<PAGE>
Company,  in good faith,  may amend such  registration  statement to exclude the
Shares  without  otherwise  affecting the Warrant  Holder's  rights to any other
registration statement herein.

     (i)Primary  Registrations.  If a Piggyback  Registration is an underwritten
primary  registration on behalf of the Company,  and if the underwriter  thereof
advises  the  Company  in  writing,  that in Its  opinion  the  number of Shares
requested to be included in such registration  statement exceeds the number that
can be  sold  in  such  offering  without  materially  adversely  affecting  the
distribution of such securities by the company, then the Company will include in
such  registration  statement first, the securities that the Company proposes to
sell and second,  the securities  requested to be included in such  registration
statement by selling Securityholders,  such right to inclusion being apportioned
pro rata among the Warrant Holder and the other holders of any other  securities
requesting  registration  according  to the  market  value of  Shares  and other
securities requested to be registered.

         Notwithstanding  the above,  if any such  underwriter  shall advise the
Company in writing that the  distribution  of the Shares being  included in the
registration  statement concurrently with the securities being registered by the
Company would materially adversely affect the distribution of such securities by
the Company,  then the Warrant Holder shall delay its offering and sale for such
period ending on the earliest of (a) 180 days  following  the effective  date of
the Company's registration statement, (b) the earliest date that, in the opinion
of such underwriter,  such adverse effect would no longer be caused, or (c) such
date as the Company,  managing  underwriter  and Warrant Holder shall  otherwise
agree. In the event of such delay,  the Company shall file such  supplements and
post-effective amendments and take any such other actions as may be necessary or
appropriate to permit such Warrant Holder to make its proposed offering and sale
for a period of at least ninety (90) days commencing  immediately  following the
end of such period of delay.  If any party  disapproves of the terms of any such
underwriting,  it may  elect to  withdraw  therefrom  by  written  notice to the
Company,  the  underwriter  and  the  Warrant  Holder.   Notwithstanding   the
foregoing,  the  Company  shall not be  required  to include  Shares  within the
coverage of a  registration  statement  being filed pursuant to this Paragraph 7
(a) (i) if, in the opinion of counsel  for both the Company and Warrant  Holder,
all of the Shares  proposed  to be  registered  may be  immediately  transferred
pursuant to the provisions of Rule 144 under the Securities Act.

     (ii) Priority on Secondary  Registrations.  If a Piggyback Registration is
an underwritten secondary registration on behalf of holders of securities of the
Company,  and the underwriter thereof advises the Company in writing that it its
opinion  the number of Shares  requested  to be  included  in such  registration
statement  exceeds  the  number  which  can be sold in such  offering  without
materially adversely affecting  the distribution of such securities,  then the
Company will include in such registration  statement the securities requested to
be included in Such registration  statement by selling  securityholders on a pro
rata basis,  with such  rights to  inclusion  being  apportioned  among  the
Warrant  Holder  and  the  other  holders  of any  other  securities  requesting
registration  according to the market  value of Shares  and other  securities
requested  by  them,  respectively,   to  be  registered.   Notwithstanding  the
foregoing,  the Company  shall not be required  to  include  Shares  within the
coverage of a  registration  statement  being filed pursuant to this Paragraph 9
(a) (ii) if, in the opinion of counsel for both the Company and

                                        4
<PAGE>
Warrant  Holder,  all of the Shares proposed to be registered may be immediately
transferred pursuant to the provisions of Rule 144 under the Securities Act.

         (b) If at any time after August 4, 1998 and prior to the third  (3rd)
anniversary  of the earlier of the  expiration of the Warrant herein granted and
the purchase of the final  Shares  remaining  subject to such  Warrant  Shares
issued or issuable  upon  exercise of the Warrant  herein  granted are not then
registered  under one or more  Piggyback  Registrations  and then  covered  by a
prospectus  complying with the  requirements  of the Securities Act, the Warrant
Holder  may  by  written  notice  to the  Company  require  Company  to file a
registration statement under the Securities Act covering such Shares as Warrant
Holder may  specify in such  notice.  Warrant  Holder  shall be  entitled  so to
require  Company to file a registration  statement  pursuant to this Paragraph 7
(b) on only  one ( 1)  occasion.  The  Company  will  file  such a  registration
statement within ninety (90) days of receipt of such notice, and thereafter will
prosecute such registration  statement  diligently to effectiveness,  will cause
such registration statement to become effective as promptly as practicable; will
promptly  file  all  such  supplements  and  post-effective  amendments  to such
registration  statement  and take any such other  actions as may be necessary or
appropriate  to make  available to Warrant Holder on as continuous a basis as is
practicable a prospectus  meeting the requirements of the Securities Act through
the  earliest  of (a) the date on which  the  final  Shares  have  been sold and
distributed by Warrant Holder,  (b) the date on which, in the opinion of counsel
for both the Company and Warrant Holder,  all of the Shares which Warrant Holder
then holds may be immediately transferred pursuant to the provisions of Rule 144
under the  Securities  Act, and (c) August 4, 2004. In that regard,  the Company
makes  no   representations  or  warranties  as  to  its  ability  to  have  any
registration statement or post-effective amendment thereto declared effective.

         (c) In the event of any  registration  of a security  pursuant  to this
Paragraph 7, the Company shall indemnify the Warrant Holder and its officers and
directors  against all losses,  claims,  damages and  liabilities  caused by any
untrue statement or alleged untrue statement of a material fact contained in any
registration  statement or prospectus (and as amended or supplemented)  relating
to such  registration,  or caused by any omission or alleged omission to state a
material fact  required to be stated  therein or necessary to make the statement
therein not misleading in light of the  circumstances  under which they are made
unless such  statement or omission was made in reliance  upon and in  conformity
with  information  furnished to the Company by the Warrant Holder with expressly
for use therein.  The Warrant  Holder  shall also  indemnify  the  Company,  its
officers and directors  and each  underwriter  of the Shares so registered  with
respect to losses,  claims  damages  and Shares so  registered  with  respect to
losses, claims damages and liabilities caused by an untrue statement or omission
made in  reliance  upon and in  conformity  with  information  furnished  by the
Warrant Holder to the Company in writing  expressly for use in such registration
statement or prospectus.

         (d) All expenses of any  registration  referred to in this Paragraph 7,
except the fees and disbursement of counsel to the Warrant Holder,  underwriting
commissions  or  discounts  and any  transfer or other taxes  applicable  to the
transfer of Shares by the Warrant Holder, shall be borne by the Company.

<PAGE>
     (e) Following  the exercise of the Warrant  hereunder,  the Warrant  Holder
shall promptly advise the Company when Warrant Holder no longer holds any shares
acquired  through  the  exercise  of Warrants  granted  hereunder,  and upon the
request of the Company, the Warrant Holder shall advise the Company from time to
time of the number of Shares  then held by Warrant  Holder  which were  acquired
through the exercise of Warrants granted hereunder.

         8.       Adjustments Upon Changes in Capitalization.

         (a) In the event of  changes  in the  outstanding  Common  Stock of the
Company  by reason of stock  dividends,  stock  splits,  reverse  stock  splits,
recapitalization's,   consolidations,   combinations,   exchanges   of   shares,
separations,  reorganizations,  liquidation's  or any  similar  events or events
having  similar  consequences,  the  number  and class of Shares as to which the
Warrant may be exercised shall be correspondingly  adjusted so that for the same
aggregate  exercise  price the Warrant  Holder  shall be entitled to acquire the
securities and other  property  Warrant Holder would have held if Warrant Holder
had exercised  its rights to purchase  shares under this Warrant  Agreement for
the number of Shares  under  consideration  prior to the first of such events to
occur and  continued  to hold such  Shares  and all other  securities  and other
property  issued  with  respect  thereto  in  connection  with such  events.  No
adjustment  shall be made with  respect  to cash  dividends  or  non-liquidating
dividends  payable  in  property  other than cas,  so long as  Company  provides
Warrant  Holder  with  written  notice of any such  proposed  dividend  at least
fifteen (15) days prior to the record  date for such  dividend.  Company  shall
also give Warrant  Holder  prompt  written  notice of any event  resulting in an
adjustment under this Paragraph 8 (a), including a detailed  computation of such
adjustment.

         (b)  Any  adjustment  in the  number  and  kind  of  Shares  and  other
securities shall apply  proportionately  to only the unexercised  portion of the
Warrant at the time of the event given rise to the adjustment. If fractions of a
Share would result from any such adjustment,  the adjustment shall be revised to
the next  higher  whole  number of Shares  so long as such  increase  does not
result in the  holder  of the  Warrant  being  deemed to own more than 5% of the
total combined voting power or value of all classes of stock of the Company or
its  subsidiaries,  in which  case the  adjustment  shall be revised to the next
lower whole number of Shares.

         9.      Effect of Mergers, consolidations or Sales of Assets.

         In the event Company should  propose to merge or  consolidate  with, or
engage in some other form of business combination with, any other corporation or
entity on a basis in which Company is not to be the surviving entity,  then as a
condition  precedent  to  proceeding  with such merger,  consolidation  or other
business  combination,  the Company shall require the surviving entity to assume
and perform  all of  Company's  obligations  under the right to acquire the same
securities  and  property for the Warrant  exercise  price  specified  herein as
Warrant  Holder would have received if Warrant  Holder had exercised the Warrant
immediately prior to such merger,  consolidation or other business  combination.
To the extent the above may be  inconsistent  with Sections 424 (a) ( 1) and (2)
of the Code, the above shall be deemed interpreted so as to comply therewith.

                                        6
<PAGE>
         10,     No Rights in Warrant Stock.

         Warrant  Holder  shall  have no rights as a  shareholder  in respect of
Shares as to which the  Warrant  hereunder  shall  not have been  exercised  and
payment made as herein provided.


         11.     Effect Upon Employment.

         This Agreement does not give the Warrant Holder any right to employment
by, or any other relationship with, the Company.

         12.    Binding Effect.

         Except as herein otherwise expressly provided,  this Agreement shall be
binding upon and inure to the benefit of the parties hereto,  their  successors,
legal representatives and assigns.

         13. Miscellaneous.

                    ii. MSP  acknowledges  and agrees  that  MasterCard  has the
                    right to enforce any provision of the  MasterCard  Rules and
                    to prohibit any conduct by MSP that creates a risk of injury
                    to MasterCard or that may adversely  affect the integrity of
                    MasterCard's  systems,  information  or both.  MSP agrees to
                    refrain from taking any action that would have the effect of
                    interfering  with or preventing an exercise of such right by
                    MasterCard; and

                    in the event of any  inconsistency  between any provision of
                    this  Agreement and the  MasterCard  Rules,  the  MasterCard
                    Rules will be afforded precedence and shall apply.

4.       CONDENSATION TO MSP

         A.    Processing Rates and Fees. NOVA,  acting on its own behalf and as
               Member's  agent,  shall  pay  to MSP as  full  consideration  and
               compensation   for  the  performance  of  all  MSP's  duties  and
               obligations under this Agreement,  any Referred Merchant discount
               revenues and/or fees collected in excess of NOVA's fees and other
               charges as set forth on Schedule B. Such  payments  shall be made
               within  thirty  (30)  days  following  the  end  of  each  month;
               provided,  however,  NOVA shall use its best efforts to make such
               payments  within  fifteen  (15)  days  following  the end of each
               month. For example,  amounts payable to MSP for Referred Merchant
               revenues collected for March Transactions shall be paid to MSP by
               April 30,  but NOVA will  attempt to pay such  revenues  by April
               15).

         B.    Pass-Through  of Certain Fees.  NOVA and Member reserve the right
               to pass through to MSP certain  fees or penalties  imposed by any
               Credit Card  Association as a result of the  activities,  acts or
               omissions  of MSP.  Additionally,  MSP agrees to pay promptly any
               fees or penalties  imposed by the Credit Card  Associations  with
               respect to MSP's  registration as a service  provider for Member.
               MSP acknowledges that NOVA and Member, in their discretion and in
               accordance  with the terms of the Merchant  Agreements,  may pass
               through to Referred  Merchants  any fees or  expenses  related to
               implementing  changes to  software/hardware  requirements  deemed
               necessary  by the  Credit  Card  Associations  or  other  service
               providers.

5.       DUE CARE AND LIABILITY

MSP  hereby  agrees  to  indemnify  and  hold  NOVA,  Member,  the  Credit  Card
Associations,  the  Referred  Merchants  and  the  members  of the  Credit  Card
Associations  harmless from and against any claim,  demand,  loss,  financial or
otherwise,  damage,  liability  or cost  (including  reasonable  legal  fees and
expenses), caused by or in any way arising from: (i) any failure by MSP to fully
comply with the Rules and all other rules, regulations,  policies and procedures
of NOVA,  Member,  MasterCard,  VISA and any other similar Credit Card licensor;
(ii) any  breach or  default  by MSP of this  Agreement  or any other  agreement
between MSP and (a) NOVA,  (b) Member or (c) any  Referred  merchant;  (iii) any
negligent  or  wrongful  act of MSP in  performing  or failing  to  perform  the
obligations  hereunder;  or (iv) any  termination of this Agreement  pursuant to
Section 8 hereunder.  The obligations of MSP hereunder are not intended to cover
typical credit losses  (including  chargebacks)  incurred by NOVA or Member as a
result of Referred  Merchants'  refusal or inability to pay,  unless such credit
losses are  incurred by NOVA or Member as a result of any act or omission or MSP
described in (i) - (iv) above.

         F.    Dispute Resolution. Any controversy, dispute or claim arising out
               of, or in connection with this Agreement must be settled by final
               and  binding  arbitration  to be  held  in  Atlanta,  Georgia  in
               accordance with the rules of the American Arbitration Association
               ("AAA"),  as may be amended from time to time (the "AAA  Rules").
               Judgment upon award rendered by the arbitrators may be entered in
               any  court:  (i)  having   jurisdiction   thereof,   (ii)  having
               jurisdiction  over the party against whom enforcement  thereof is
               sought,  or (iii)  having  jurisdiction  over  any such  party's
               assets.  The procedures and law applicable during the arbitration
               of any  controversy,  dispute or claim will be both the AAA Rules
               and  the  internal  substantive  laws  of the  State  of  Georgia
               (excluding, and without regard to, its or any other

                                        7
<PAGE>
               jurisdiction's  rules  concerning  any conflict of laws).  In any
               arbitration  pursuant  to this  Agreement,  the award of decision
               must be  rendered  by at least a  majority  of the  members of an
               arbitration  panel  consisting of three (3) members,  one of whom
               will be appointed by each of the parties hereto.  All arbitrators
               must be persons who are not employees, agents or former employees
               or agents of any  party.  In the  event  that any of the  parties
               hereto  fails to appoint an  arbitrator  within  thirty (30) days
               after  submission of the dispute to arbitration,  such arbitrator
               will be appointed by the AAA in accordance with the AAA Rules.

         G.       Force Majeure.  Neither party shall be liable to the other for
                  any failure or delay in its  performance  of this Agreement in
                  accordance  with its terms if such failure or delay arises out
                  of  causes  beyond  the  control  and  without  the  fault  or
                  negligence of such party.

         H.       Waiver.  Any waiver or delay by any party  hereto in asserting
                  or exercising any right,  shall not constitute a waiver of any
                  further  or other  rights of said  party.  If any part of this
                  Agreement   shall   be  held  to  be   invalid,   illegal   or
                  unenforceable, the validity, legality or enforceability of the
                  remainder of the Agreement shall not in any way be affected or
                  impaired thereby.

         1.       Attorney's  Fees. In the event any party hereto is determined,
                  in connection with a final and binding arbitration pursuant to
                  Section 6.F above, to have breached this  Agreement,  then the
                  non-defaulting  party shall be  entitled  to recover  expenses
                  incurred  in  enforcing  the  provisions  of  this  Agreement,
                  including reasonable attorneys' fees and costs.

         J.       Severability,  If any  provision  of this  Agreement  is found
                  illegal,  invalid  or  unenforceable,  such  finding  will not
                  affect any other provision hereunder.  This Agreement shall be
                  deemed modified to the extent necessary to render  enforceable
                  the provisions hereunder, and to comply with the Rules.

         one-year  terms,  unless any party hereto  provides  the other  parties
         written  notice of intent not to renew this  Agreement  at least ninety
         (90) days prior to the  expiration of the then current term.  The terms
         of  this   Agreement   shall  remain  in  force  with  respect  to  all

                    iii, the appointment of a trustee, conservator,  receiver or

CONFIDENTIAL  TREATMENT  REQUESTED  BY U.S.  WIRELESS  DATA,  INC.  FOR  CERTAIN
INFORMATION CONTAINED IN PARAGRAPH 4 OF THIS AGREEMENT



U.S. WIRELESS DATA(R) INC.
Delivering The New Standard In Transaction Processing

September 18, 1997


Mr. David Ivy, Sr.
Unicard Systems, Inc.
13800 Montfort #155
Dallas, TX 75240


Dear David,

I am writing this letter of  understanding  to outline the terms of an agreement
between U.S.  Wireless Data and Unicard  Systems,  Inc. The execution of a final
agreement will result in a high speed, efficient and cost effective solution for
providing both Unicard processing and credit card transaction processing for the
current and future customers of Unicard Systems, Inc.

I have outlined  below the basic terms and  conditions  of an agreement  between
U.S.  Wireless Data ("USWD") and Unicard  Systems,  Inc. ("USI") for your review
and acceptance:

         1. Unicard  desires to incorporate  U.S.  Wireless Data's TRANZ Enabler
and CDPD wireless services to speed up the Unicard authorization process for its
current and future customers.

         2. USI  agrees  to  utilize  USWD's  TRANZ  Enabler  and CDPD  wireless
services as its  exclusive  wireless  product and  service  offering.  The TRANZ
Enabler  is  compatible  for use with the  Verifone  Zon Jr.,  TRANZ 330 and 380
terminals.

         3. USI and USWD also desire to offer credit card transaction processing
services to USI's current and future customers.

         4. USWD will provide its TRANZ Enabler and wireless  services to USI at
a rental rate of * per month.  This rental fee includes the TRANZ  Enabler,  and
CDPD wireless  services  (includes IP address,  monthly service fee and air time
usage up to 20 KB per month).  The first * monthly  rental charge will be due 30
days after  receipt of  shipment  of the units with  subsequent  monthly  rental
payments due on the first day of each month.

         5. USWD has  developed a CDPD version of the USI  terminal  application
software and has certified it for use on the USI host. The application  software
is jointly  owned by USWD and USI and may not be  licensed  for use to any other
customers without the written consent of both parties.

         6. USWD will provide USI with  detailed CDPD coverage maps to determine
CDPD coverage at all proposed deployment sites.

         7.  USWD will  provide  warranty  and  support  services  for its TRANZ
Enabler  under  normal wear and tear  conditions.  USWD will  provide USI with a
replacement   pool  (5  units)  to  swap  out  damaged  units.  Any  damaged  or
malfunctioning  units will be repaired by USWD and put back into the replacement
pool.  The  replacement  pool will be provided to USI on a no cost basis and may
only be used for replacing defective or damaged units.

         8. In the  event  that a unit is lost,  stolen  or part of a  "midnight
move",  then USWD  would  apply 50% of the rental  payments  made to date by USI
towards a $500 replacement  cost. Units damaged due to abuse will be repaired on
a time and materials basis.

         9.  USI will  become a  registered  agent  of USWD for the  purpose  of
offering credit card transaction  processing  services to its current and future
customers.

         10. USWD will develop and certify a single USI and Credit Card terminal
application  for use with a Verifone  TRANZ 330 or 380  terminal.  This terminal
application will allow a merchant to process membership cards with USI or credit
cards with USWD's  credit card  processor.  USWD will develop  this  application
software at its own expense and will  retain 100%  ownership  of the code.  USWD
will  license  the  hybrid  application  software  to USI  free  of  charge  for
utilization only with USI's current and future customer base.

         11.  USI and USWD  agree to split any  recurring  revenue  earned  from
credit card transaction  processing on an equal (50/50) basis. Recurring revenue
is defined as the margin  between USWD's "buy rate" and the discount rate quoted
to the  merchant  net of any  fixed  monthly  costs.  USWD will fund USI for its
portion of recurring  revenue  earned on the 20th of each month.  The  recurring
revenue fees only apply to Visa and Mastercard  transactions.  American  Express
and  Discover  quote  discount  rates to the  merchant  directly,  and we cannot
participate  in any  recurring  discount  rate  fees for AMEX or  Discover  Card
transactions.

         12. USI will provide USWD with an initial  purchase order for 400 units
with   specified   delivery   dates  upon  the  acceptance  of  this  letter  of
understanding.

         13. Upon the signing of the acceptance of this letter of understanding,
USI agrees to allow USWD to issue a press release  describing the general nature
of this agreement.

         * #14 below
I believe this outline covers the basic terms of an agreement that can make this
relationship a mutual success for our respective companies. If agreeable, please
indicated  by signing  below and  return it to me with a purchase  order for the
first 400 units at your earliest convenience.  Upon receiving your acceptance, I
will  have  our  legal  firm  draft  a  formal  agreement  to be  executed  that
incorporates the terms and conditions stated above.

Sincerely,                         Accepted this 18th day of September, 1997

         14. The parties agree that certain trade secrets, customer lists and/or
other techniques used in the present business of USI will or may be disclosed to
USWD. Therefore, USWD agrees that it will not offer the same services covered by
this  agreement to any other  company for  purposes of private  club  membership
management in Texas.
