Item 5:  Other Events

          All  references  to "we" or "us"  contained  in this Form 8-K refer to
U.S.  Wireless  Data,  Inc. The  following  descriptions  of  agreements we have
entered into are  summaries  and are  qualified  by reference to the  agreements
which we filed as exhibits to this report.

          On December 23, 1999, we entered into an agreement  with an investment
banking  firm in  connection  with a  proposed  equity  private  placement.  The
securities  contemplated to be issued in the proposed  equity private  placement
will not be, and the securities issued in the bridge financing referred to below
have not been,  registered under the Securities Act of 1933, as amended, and may
not be offered or sold in the United States absent registration or an applicable
exemption from registration requirements.

          In  connection  with the  engagement  of the bank,  we entered into an
agreement on December 30, 1999,  with an entity  affiliated  with the bank under
which it agreed to lend us up to  $1,000,000,  subject  to  certain  conditions,
including that (a) Dean M. Leavitt, our Chief Executive Officer,  make and honor
a similar commitment to lend us up to $100,000, (b) Mr. Leavitt remain our Chief
Executive  Officer and a director and (c) we are able to enter into an agreement
to convert,  modify or purchase our outstanding  Series B Preferred Stock and 6%
Convertible  Debentures on terms acceptable to the lender. The loans are secured
by substantially all of our assets pursuant to a General Security  Agreement and
each loan is evidenced by a note, bearing interest at a rate of 8% per annum and
due on the  earlier of (x) the date a change of control (as defined in the note)
occurs,  (y) the date we conclude a debt or equity financing in which we receive
at least  $5,000,000  of gross  proceeds,  or (z) December  30, 2000.  The notes
include certain  negative  covenants,  including  prohibitions on the payment of
certain dividends, redemptions and asset sales and limitations on the incurrence
of indebtedness, liens and the issuance, prior to March 31, 2000, of securities.
The lenders may, at their option,  convert the outstanding  principal  amount of
the notes  into  securities  issued in  connection  with any  private  placement
transaction on the same terms as investors in such  placement.  In addition,  we
have agreed to appoint a designee of the bank  affiliate  lender to our board of
directors  and to have an  observer  present  at all  meetings  of our  board of
directors.  The  bank  affiliate  lender  has  not  yet  named  anyone  to  this
directorship.  These rights expire after the note and any subsequent  notes have
been satisfied.

          In connection with the  commitments to lend up to $1,100,000,  we also
issued the bank affiliate lender a warrant to purchase  13,636,363 shares of our
common  stock at an  exercise  price of $0.01  per  share  and we  issued to Mr.
Leavitt a similar warrant to purchase  1,363,637 shares of our common stock. The
warrants may be exercised at any time, subject to certain conditions,  including
the  approval  by  our   shareholders   of  an  amendment  to  our  Articles  of
Incorporation  to increase the number of our authorized  shares of common stock.
The warrants  expire on December 30, 2006. If the bank is unable or unwilling to
complete the private  placement  contemplated  by the December  23rd  agreement,
then, subject to certain  exceptions  described below, the lenders will pay us a
break-up fee of $5,000,000,  payable at the lenders' option either in cash or by
cancellation  of 50% of the warrants.  Such break-up fee would not be payable if
certain events occur, including (a) certain breaches by us, (b) Mr. Leavitt's no
longer  being an officer and  director,  (c) our being  unable to  increase  our



                                       2

authorized preferred and common stock by April 28, 2000 and (d) our being unable
to enter  into  agreements  to  redeem,  convert,  amend or retire  the Series B
Preferred  Stock  or 6%  Convertible  Debentures  by  March  1,  2000  on  terms
satisfactory  to the bank.  The lender and Mr.  Leavitt have certain  demand and
"piggyback"  registration  rights,  commencing in June 2000, as to the shares of
common stock underlying the warrants.

          Currently,  we do not have  enough  authorized  common  stock  for the
warrants to be exercised.  As a result,  we entered into Economic  Participation
Agreements  with the lenders  which are intended to provide the lenders with the
economic  equivalent of ownership of the shares of common stock  underlying  the
warrants in the event that we are unable to amend our Articles of  Incorporation
to  increase  the number of  authorized  shares of common  stock.  The  Economic
Participation Agreements terminate at such time as a sufficient number of shares
of our common stock is authorized and reserved for issuance upon the exercise of
the warrants,  unless we have failed to amend our Articles of  Incorporation  by
April 28,  2000,  in which case the lenders are entitled to  liquidated  damages
which are calculated in accordance with the agreement.

          As of January  10,  2000,  we had  received an  aggregate  of $500,000
pursuant to the bridge  financing  described  above,  of which  $466,298.33  was
received from the lender and $33,701.66 was received from Mr. Leavitt.

THE WARRANT  REPRESENTED BY THIS  CERTIFICATE  AND THE SECURITIES  ISSUABLE UPON
EXERCISE  HEREOF HAVE NOT BEEN  REGISTERED  UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "ACT"). NEITHER THIS WARRANT NOR SUCH SECURITIES MAY BE TRANSFERRED
EXCEPT (A) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT AND ANY
APPLICABLE STATE SECURITIES LAWS OR (B) UPON RECEIPT BY THE ISSUER OF AN OPINION

                            U.S. WIRELESS DATA, INC.


Warrant No. _____


     THIS CERTIFIES that, for value received, ______________________________, or
its permitted assigns registered on the books of the Company (collectively,  the
"Holder"),  is entitled to purchase from U.S.  Wireless  Data,  Inc., a Colorado
corporation  (the  "Company"),  at any time,  and from time to time,  during the
exercise  period  referred  to in  Section  1  hereof,  __________  shares  (the
"Shares") of fully paid and nonassessable  shares of common stock of the Company
(the "Common  Stock").  The purchase price for each Share (the "Share Price") is
one cent ($0.01) per Share.  Securities  issuable  upon exercise of this Warrant
and the price payable  therefor are subject to  adjustment  from time to time as
hereinafter  set forth.  As used herein,  the term  "Warrant"  shall include any
warrant or warrants  hereafter  issued in  consequence  of the  exercise of this
Warrant in part or transfer of this Warrant in whole or in part.

1. Exercise;  Payment for Ownership Interest.  Upon the terms and subject to the
conditions  set forth herein,  this Warrant may be exercised in whole or in part
by the  Holder  hereof at any time,  or from time to time,  on or after the date
hereof  and  prior  to 5 p.m.  San  Francisco  time  on  December  30,  2006  by
presentation  and  surrender  of this  Warrant to the  principal  offices of the
Company,  together with the Purchase Form annexed  hereto,  duly  executed,  and
accompanied  by payment to the  Company  of an amount  equal to the Share  Price
multiplied  by the  number of  Shares as to which  this  Warrant  is then  being
exercised;  provided,  however,  the Holder may not exercise this Warrant to the
extent such exercise  would exceed the number of shares of Common Stock reserved
for issuance under this Warrant it being agreed that on the date of this Warrant
no shares of Common Stock have been duly  reserved for  issuance.  If the Holder
has exercised  all or any portion of this Warrant  within six months of the date
of this  Warrant the Holder may not during such period sell,  assign,  transfer,

                                      -1-

<PAGE>



pledge or  encumber  any such  shares to the  extent any such  shares  exceeds a
number (the "Excess  Shares")  equal to the product of (1)  __________ and (2) a
fraction the numerator of which is the sum of all loans made by ________________
________________ to the Company pursuant to the Commitment Letter dated December
30, 1999 and the  denominator of which is  $1,000,000.  In the event that within
six months of the date of this Warrant,  the Company shall have requested  funds
under the Commitment Letter and ________ shall not have honored any such request
for financing that it is required to honor by the terms of the Commitment Letter
and the promissory note relating to such borrowing  request,  then in respect of
such  failure to honor such  request  the Holder  shall  forfeit to the  Company
(either in shares of Excess Shares,  warrants to purchase shares of Common Stock
that have not yet been  exercised  but that if  purchased  by the  Holder  would
constitute  Excess Shares,  or a combination of both, in each case at the option
of the Holder)  that number of shares of Common Stock as is equal to the product
of (1)  __________  and (2) a fraction the  numerator of which is the sum of (x)
the amount of funds represented by the borrowing request that ________ failed to
honor but was  required  to do so and (y) the amount of  borrowing  at that time
that  the  Company  may  still  request  under  the  Commitment  Letter  and the
denominator  of which is $1,000,000.  If the Holder  forfeits any Excess Shares,
then within five (5) business  days of the date of  forfeiture  the Company will
pay to the  Holder  the  exercise  price  paid to the  Company  by the Holder to
purchase  such  Excess  Shares.  Any  transfer  of Shares  obtained by Holder in
exercise of this Warrant is subject to the requirement  that such securities are
registered  under the  Securities  Act of 1933,  as amended (the "1933 Act") and
applicable  state  securities  laws or are exempt from  registration  under such
laws.  The Holder of this  Warrant  shall be deemed to be a  shareholder  of the
Shares as to which this Warrant is exercised in  accordance  herewith  effective
immediately  after the close of business  on the date on which the Holder  shall
have  delivered  to the Company  this  Warrant in proper form for  exercise  and
payment  by  certified  or  official  bank  check or wire  transfer  of the cash
purchase  price for the number of Shares as to which the exercise is being made,
or by delivery to the Company of securities of the Company  having a value equal
to the cash purchase  price for such number of Shares  determined as of the date
of delivery. If this Warrant shall be exercised in part only, the Company shall,
upon  surrender  of this  Warrant  for  cancellation,  execute and deliver a new
Warrant  evidencing  the rights of the Holder thereof to purchase the balance of
the Shares purchasable hereunder as to which the Warrant has not been exercised.
If this Warrant is exercised in part,  such exercise shall be for a whole number
of Shares. Upon any exercise and surrender of this Warrant, the Company (a) will
issue and deliver to the Holder a certificate or certificates in the name of the
Holder  for the  largest  whole  number of Shares to which the  Holder  shall be
entitled and, if this Warrant is exercised in whole,  in lieu of any  fractional
Share to which the Holder  otherwise might be entitled,  cash in an amount equal
to the fair value of such  fractional  share  (determined in such reasonable and
equitable  manner as the Board of Directors  of the Company  shall in good faith
determine), and (b) will deliver to the Holder such other securities, properties
and cash which the Holder may be entitled to receive upon such exercise,  or the
proportionate part thereof if this Warrant is exercised in part, pursuant to the
provisions of this Warrant.

2. Adjustments.  Securities issuable upon exercise of this Warrant and the Share
Price shall be subject to adjustment from time to time as follows:

     2.1  Reorganization,  Reclassification,   Consolidation,  Merger  or  Sale;
Distributions.

          (a) If any capital  reorganization or reclassification of the Company,
or any  consolidation or merger of the Company with another person, or the sale,
transfer or lease of all or  substantially  all of its assets to another  person
shall be effected in such a way that  holders of shares of Common Stock shall be
entitled to receive  stock,  securities or assets with respect to or in exchange
for their shares,  then provision shall be made, in accordance with this Section
2.1,  whereby the Holder hereof shall  thereafter have the right to purchase and
receive,  upon the basis and upon the terms  and  conditions  specified  in this
Warrant  Agreement  and in addition to or in exchange  for, as  applicable,  the
Shares  subject  to  this  Warrant  immediately   theretofore   purchasable  and
receivable upon the exercise of the rights represented  hereby,  such securities
or assets as would have been  issued or payable  with  respect to or in exchange
for the aggregate Shares immediately theretofore purchasable and receivable upon
the  exercise  of the rights  represented  hereby if exercise of the Warrant had
occurred   immediately   prior   to   such   reorganization,   reclassification,
consolidation,   merger  or  sale.   The  Company   will  not  effect  any  such
consolidation,  merger, sale, transfer or lease unless prior to the consummation
thereof the  successor  entity (if other than the Company)  resulting  from such
consolidation  or merger or the entity  purchasing  or leasing such assets shall
assume by written  instrument  (i) the obligation to deliver to such Holder such
securities  or assets as, in  accordance  with the  foregoing  provisions,  such
Holder  may be  entitled  to  purchase,  and (ii) all other  obligations  of the
Company  under  this  Warrant.  The  provisions  of this  Section  2.1(a)  shall
similarly  apply  to  successive  consolidations,   mergers,  exchanges,  sales,
transfers or leases.

          (b) If,  at any  time or from  time  to time  after  the  date of this
Warrant,  the Company shall  distribute to the holders of shares of Common Stock
(i)  securities,  (ii)  property,  other than cash, or (iii) cash,  without fair
payment therefor,  then, and in each such case, the Holder, upon the exercise of
this Warrant,  shall be entitled to receive such  securities,  property and cash
which the Holder would hold on the date of such exercise if, on the date of this
Warrant,  the Holder had been the holder of record of the shares of Common Stock
subscribed  for upon such exercise and,  during the period from the date of this
Warrant to and including the date of such exercise,  had retained such shares of
Common  Stock and the  securities,  property and cash  receivable  by the Holder
during such period,  subject,  however, to the Holder agreeing to any conditions
to such  distribution  as were required of all other Holders of shares of Common

                                      -3-


<PAGE>



Stock in connection with such distribution.  If the securities to be distributed
by  the  Company  involve  rights,  warrants,  options  or  any  other  form  of
convertible  securities  and the right to  exercise or convert  such  securities
would expire in accordance with its terms prior to the exercise of this Warrant,
then  the  terms  of  such  securities  shall  provide  that  such  exercise  or
convertibility  right shall  remain in effect  until  thirty (30) days after the
date the  Holder  of this  Warrant  receives  such  securities  pursuant  to the
exercise hereof.

          (c) In addition to those  adjustments set forth in Sections 2.1(a) and
(b), but without  duplication of the adjustments to be made under such Sections,
if the Company:

               (i)  pays a dividend or makes a distribution  on its Common Stock
                    in shares of its Common Stock;

               (ii) subdivides  its  outstanding  shares of Common  Stock into a
                    greater number of shares;

               (iii)combines  its  outstanding  shares  of Common  Stock  into a
                    smaller number of shares;

               (iv) makes a distribution on of its Common Stock in shares of its
                    capital stock other than Common Stock; and/or

               (v)  issues, by  reclassification of its Common Stock, any shares
                    of its capital stock;

then the number and kind of Shares  purchasable  upon  exercise of this  Warrant
shall be adjusted so that the Holder upon  exercise  hereof shall be entitled to
receive the kind and number of Shares or other  securities  of the Company (such
other  securities  thereafter  enjoying the rights of Shares under this Warrant)
that the  Holder  would have owned or have been  entitled  to receive  after the
happening of any of the events  described  above had this Warrant been exercised
immediately prior to the happening of such event or any record date with respect
thereto.  An  adjustment  made  pursuant to this  Section  2.1(c)  shall  become
effective  immediately  after  the  record  date in the  case of a  dividend  or
distribution and shall become effective  immediately after the effective date in
the case of a  subdivision,  combination  or  issuance.  If,  as a result  of an
adjustment  made  pursuant to this  Section  2.1(c),  the Holder of this Warrant
thereafter  surrendered  for exercise shall become entitled to receive shares of
two or more  classes  of capital  stock or shares of Common  Stock and any other
class  of  capital  stock  of  the  Company,   the  Board  of  Directors  (whose
determination  shall be conclusive and shall be described in a written notice to
all holders of this Warrant promptly after such adjustment)  shall determine the

                                      -4-


<PAGE>



allocation  of the adjusted  Share Price between or among shares of such classes
of  capital  stock or shares of Common  Stock and such  other  class of  capital
stock.

          The adjustment to the number of Shares  purchasable  upon the exercise
of this Warrant  described  in this  Section  2.1(c) shall be made each time any
event listed in paragraphs (i) through (v) of this Section 2.1(c) occurs.

          (d)  Simultaneously  with all adjustments to the number and/or kind of
securities,  property and cash to be issued in  connection  with the exercise of
this Warrant, the Share Price will also be appropriately adjusted so that at all
times the Holder and all subsequent holders of this Warrant (whether in whole or
in part) would not pay more than the aggregate  purchase  price to exercise this
Warrant in full  immediately  after such  adjustment  as the Holder and all such
subsequent holders had to pay immediately prior to such adjustment.

     2.2  Other  Action  Affecting  Shares.  If the  Company  takes  any  action
affecting  its  shares of Common  Stock  after the date  hereof,  that  would be
covered  by  Section  2.1 but for the  manner in which  such  action is taken or
structured, other than an action described in any of Section 2.1, which would in
any way diminish the value of this Warrant hereunder, then this Warrant shall be
adjusted as to the Shares  purchasable  hereunder  and the Share  Price  payable
hereunder in such manner as the Board of Directors of the Company  shall in good
faith determine to be equitable under the circumstances.

     2.3 Notice of  Adjustments.  Upon each  adjustment or  readjustment  of the
Share Price or in the nature of the securities or other property receivable upon
the exercise of this Warrant,  the Company at its expense will promptly  compute
such adjustment or readjustment in accordance with the terms of this Warrant and
prepare a certificate  setting forth such adjustment or readjustment and showing
in detail the facts upon which such  adjustment or  readjustment  is based.  The
Company will forthwith  mail, by first class mail,  postage  prepaid,  a copy of
each such certificate  addressed to the Holder of this Warrant at the address of
such Holder as shown on the books of the Company.

     2.4 Other Notices. If at any time:

          (a) the  Company  shall  (i) offer  for  subscription  pro rata to the
holders of shares of the Common  Stock any  additional  equity in the Company or
other rights;  (ii) pay a dividend in  additional  shares of the Common Stock or
distribute  securities or other  property to the holders of shares of the Common
Stock (including,  without limitation,  evidences of indebtedness and equity and
debt  securities);  or (iii) issue  securities  convertible  into,  or rights or
Warrants to purchase, securities of the Company;

                                      -5-



<PAGE>



          (b) there shall be any capital  reorganization or  reclassification or
consolidation  or merger of the Company with, or sale,  transfer or lease of all
or substantially all of its assets to, another entity; or

          (c) there shall be a voluntary or involuntary dissolution, liquidation
or winding up of the Company;

then,  in any one or more of said cases,  the Company shall give, by first class
mail, postage prepaid, addressed to the Holder of this Warrant at the address of
such  Holder as shown on the books of the  Company,  (a) at least 15 days' prior
written  notice of the date on which the books of the  Company  shall close or a
record shall be taken for such subscription  rights,  dividend,  distribution or
issuance,  and (b) in the  case of any  such  reorganization,  reclassification,
consolidation, merger, sale, dissolution, liquidation or winding up, at least 15
days'  prior  written  notice of the date when the same  shall  take place if no
stockholder  vote is required and at least 15 days' prior written  notice of the
record date for stockholders  entitled to vote upon such matter if a stockholder
vote is required.  Such notice in accordance with the foregoing clause (a) shall
also specify, in the case of any such subscription rights, the date on which the
holders of shares of Common  Stock shall be entitled  to exercise  their  rights
with respect  thereto,  and such notice in accordance with the foregoing  clause
(b) shall also  specify the date on which the holders of shares of Common  Stock
shall be entitled to exchange  their  shares of Common Stock for  securities  or
other  property   deliverable   upon  such   reorganization,   reclassification,
consolidation, merger, sale, dissolution, liquidation or winding up, as the case
may be.

3. No Voting Rights. Except as otherwise provided herein, this Warrant shall not
be deemed to  confer  upon the  Holder  any  right to vote or to  consent  to or
receive  notice as a  stockholder  of the  Company,  as such,  in respect of any
matters whatsoever,  or any other rights or liabilities as a stockholder,  prior
to the exercise hereof.

4.       Warrants Transferable.

          This Warrant and all rights hereunder are transferable, in whole or in
part,  at the  principal  offices  of the  Company by the  Holder  hereof,  upon
surrender of this Warrant properly endorsed; provided, however, that without the
prior written consent of the Company,  this Warrant and all rights hereunder may
be  transferred  only  (i) to an  affiliate  of the  initial  Holder  hereof  or
successor in interest to any such person;  or (ii) pursuant to the  registration
of this Warrant or the Shares under the 1933 Act or  subsequent to one year from
the date  hereof  an  exemption  under  Rule 144 or other  exemption  from  such
registration.

5.  Warrants  Exchangeable;  Loss,  Theft,  Destruction,  Etc.  This  Warrant is
exchangeable,  upon  surrender  hereof by the  Holder  hereof  at the  principal
offices of the  Company,  for new  Warrants  of like tenor  representing  in the
aggregate  the right to  subscribe  for and  purchase  the  Shares  which may be

                                      -6-



<PAGE>


subscribed for and purchased  hereunder,  each such new Warrant to represent the
right to  subscribe  for and  purchase  such  Shares  (not to exceed the maximum
aggregate  Shares which may be purchased  hereunder)  as shall be  designated by
such  Holder  hereof at the time of such  surrender.  Upon  receipt of  evidence
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this  Warrant  and,  in the case of any such loss,  theft or  destruction,  upon
delivery of a bond or indemnity  satisfactory to the Company, or, in the case of
any such mutilation, upon surrender or cancellation of this Warrant, the Company
will issue to the Holder  hereof a new  Warrant of like  tenor,  in lieu of this
Warrant,  representing  the right to subscribe for and purchase the Shares which
may be subscribed for and purchased hereunder.

6.  Legends;   Investment   Representations.   Any  certificate  evidencing  the
securities  issued  upon  exercise  of  this  Warrant  shall  bear a  legend  in
substantially the following form:

          THE  SECURITIES   REPRESENTED  BY  THIS   CERTIFICATE  HAVE  NOT  BEEN
     REGISTERED  UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT").  SUCH
     SECURITIES  MAY NOT BE  TRANSFERRED  EXCEPT (A)  PURSUANT  TO AN  EFFECTIVE
     REGISTRATION  STATEMENT UNDER THE ACT AND ANY APPLICABLE  STATE  SECURITIES
     LAWS OR (B) UPON  RECEIPT BY THE ISSUER OF AN  OPINION  OF  COUNSEL,  WHICH
     OPINION OF COUNSEL SHALL BE REASONABLY  SATISFACTORY TO THE ISSUER,  TO THE
     EFFECT THAT SUCH  TRANSFER IS EXEMPT  FROM  REGISTRATION  UNDER THE ACT AND
     SUCH STATE SECURITIES LAWS.

7.       Registration.

     7.1  Definitions.  The  following  additional  definitions  shall apply for
purposes of this Section 7:

          (a) The term "Abbreviated Registration Statement" means a registration
statement  on Form S-3 or any  similar  or  successor  form in  which  financial
statements and other detailed  information  about the issuer are incorporated by
reference from the issuer's periodic reports filed under Securities Exchange Act
of 1934, as amended (the "1934 Act").

          (b) The term "1933 Act" means the  Securities Act of 1933, as amended,
or any successor legislation thereto.

          (c) The terms "register,"  "registered," and "registration" refer to a
registration  effected  by  preparing  and filing a  registration  statement  or
similar  document  in  compliance  with the 1933  Act,  and the  declaration  or
ordering of effectiveness of such registration statement or document.

                                      -7-



<PAGE>



          (d) The term "Registrable Securities" means (1) the Shares issuable or
issued upon  exercise of this  Warrant,  and (2) any  securities  of the Company
issued as (or issuable upon the conversion or exercise of any Warrant,  right or
other security which is issued as) a dividend or other distribution with respect
to, or in exchange  for or in  replacement  of, such  Shares,  excluding  in all
cases, however, any Registrable  Securities sold by a person in a transaction in
which his rights under this  Section 7 are not assigned and any such  securities
as to which  restrictive  legends  restricting  transfer  under the 1933 Act are
lifted pursuant to Rule 144(k) under the 1933 Act (or any successor rule) or any
other  exemption  from  registration  under the 1933 Act in which the subsequent
disposition of such securities by the Holder does not require registration under
the 1933 Act.

     7.2 Right to Include  Registrable  Stock.  After six months  after the date
hereof, if the Company proposes to register any of its securities under the 1933
Act for its own account for sale for cash (other than a registration on Form S-4
or Form S-8, or any successor or similar forms) (the  "Offering"),  it will each
such time promptly give written notice to the Holder.  Upon the written  request
of the Holder made  within 15 days after the  receipt of any such notice  (which
request shall specify the Registrable  Securities  intended to be disposed of by
such Holder and the intended method of distribution  thereof),  the Company will
use its reasonable  efforts to effect the registration under the 1933 Act of all
Registrable  Securities  which the Company has been requested to register by the
Holder in accordance with the intended methods of distribution specified in such
request;  provided that (i) if, at any time after giving  written  notice of its
intention  to register any  securities  and prior to the  effective  date of the
registration  statement filed in connection with such registration,  the Company
determines for any reason not to register such  securities,  the Company may, at
its  election,  give  written  notice of such  determination  to the Holder and,
thereupon,  will be  relieved of its  obligation  to  register  any  Registrable
Securities in connection with such registration, (ii) in case of a determination
by the Company to delay  registration  of its  securities,  the Company  will be
permitted  to delay the  registration  of  Registrable  Securities  for the same
period as the delay in registering such other  securities,  and (iii) the amount
of  Registrable  Securities  of the Holder  which will be  registered  shall not
exceed a pro rata portion of all shares of Common  Stock owned by persons  other
than the Company then being  registered  in  accordance  with Section 7.4 unless
mutually agreed upon by the Holder and the Company; provided,  however, that the
provisions of this Section 7.2 will not be deemed to limit or otherwise restrict
the rights of Holder under Section 7.3 hereof.

     7.3 Demand  Registration.  At any time commencing after six months from the
date hereof, unless Commonwealth  Associates,  L.P. has been unwilling or unable
to  assist  the  Company  in  successfully  completing  a private  placement  as
contemplated in Schedule 1 of that certain  engagement letter dated December 23,
1999 between  Commonwealth  and the Company,  the Holder shall have the right on
three occasions to demand on each such occasion the registration of up to 50% of
all Registrable  Securities  originally held by the Holder,  provided that if at

                                      -8-



<PAGE>


the time of such request the aggregate value of all Registrable  Securities held
by the Holder (based on the low end of the expected  range of the offering price
of such securities) is equal to or less than $10,000,000,  the Holder may demand
the  registration of all of the Registrable  Securities then held by the Holder.
If the Holder makes such request,  the Company shall, in accordance with Section
7.5, register for sale such Registrable  Securities under the 1933 Act, provided
that the Company shall be able to delay the filing (but not the  preparation) of
any such  registration  statement  for a period of not more than sixty days from
the date it would  otherwise be required to be filed (but in any event not later
than  the next  filing  of the  Company's  Form 10-  KSB).  Notwithstanding  the
limitations  on the  Holder's  right to  demand  registration  pursuant  to this
Section  7.3,  if the  registration  statement  that  is  required  to be  filed
hereunder is withdrawn  for any reason  (which shall not in any way diminish the
obligations of the Company under Section 7.5) before, at or after effectiveness,
if the  Company  shall  fail to keep  such  registration  statement  current  as
required by Section 7.5 or if the Company shall fail to register all Registrable
Securities requested to be registered,  then in addition to any remaining demand
registration  right held by the Holder  under this Section 7.3, the Holder shall
have one additional demand  registration  right so long as the conditions herein
above set forth are satisfied.

     7.4 Priority.  If the managing underwriter for a registration  involving an
underwritten  offering advises the Company in writing that, in its opinion,  the
number of securities of the Company (including Registrable Securities) requested
to be included in such registration by the holders thereof exceeds the number of
securities  of the Company (the "Sale  Number")  which can be sold in an orderly
manner in such  offering  within a price range  acceptable  to the Company,  the
Company will,  subject to the  registration  rights  agreements  relating to the
Series B Preferred  Stock,  and the warrants  issued in conjunction  with the 6%
convertible debentures and the 6% convertible debentures, include (i) first, all
securities  of the  Company  that the Company  proposes to register  for its own
account  and (ii)  second,  to the extent that the number of  securities  of the
Company to be included by the Company is less than the Sale Number,  a number of
the  Registrable  Securities  equal to the number derived by multiplying (a) the
difference between the Sale Number and the securities proposed to be sold by the
Company,  and (b) a fraction the numerator of which is the number of Registrable
Securities  originally  requested  to  be  registered  by  the  Holder  and  the
denominator of which shall be the aggregate  number of all securities  requested
to be  registered  by  all  holders  of the  Company's  securities  (other  than
securities being registered by the Company  itself).  By way of example,  if the
Holder  requests  registration of 500 shares and only one other holder of shares
of Common Stock requests  registration and seeks to register 1000 shares and the
Company  seeks to register  3000  shares and the Sale  Number is 4200,  then the
Holder will be entitled to register 400 shares of Common Stock. The restrictions
set forth in this  Section 7.4 will no longer be  applicable  to the extent that

                                      -9-


<PAGE>


the  Company  grants  registration  rights  to any  other  holder  that are more
favorable to such holder than the registration  rights granted  hereunder and in
such event the Holder shall automatically  receive rights no less favorable than
those granted to such other holder.

     7.5 Obligations of the Company.  Whenever  required under this Agreement to
effect the  registration  of any  Registrable  Securities,  the Company will, as
expeditiously as reasonably possible:

          (a) In the case of a registration statement under Section 7.3, prepare
and file with the SEC such  registration  statement  with respect to such of the
Registrable  Securities  as  are  set  forth  in  the  request  as  promptly  as
practicable  following  the date such  obligation  arises  (but in any event not
later than 90 days  following  such date),  use its  reasonable  best efforts to
cause such  registration  statement to become  effective and use its  reasonable
best efforts to keep such  registration  statement  effective for up to one year
(nine months in the case of a registration  statement that is not an Abbreviated
Registration  Statement) but not after such securities  cease being  Registrable
Securities.

          (b) Prepare and file with the SEC such  amendments and  supplements to
such  registration  statement and the  prospectus  used in connection  with such
registration  statement as may be necessary to comply with the provisions of the
1933 Act with respect to the disposition of all Registrable  Securities  covered
by such registration statement.

          (c)  Furnish to the  Holder  such  numbers of copies of a  prospectus,
including a preliminary  prospectus,  in conformity with the requirements of the
1933 Act,  and such other  documents  as it may  reasonably  request in order to
facilitate the disposition of Registrable Securities owned by such Holder.

          (d) Use its best  efforts  to  register  and  qualify  the  securities
covered by such  registration  statement under such other securities or blue sky
laws of such  jurisdictions  as shall be  reasonably  requested  by the  Holder,
provided  that the  Company  shall not be  required  to qualify to do  business,
subject itself to taxation or to file a general consent to service of process in
any such states or jurisdictions.

          (e) Notify the Holder, at any time when a prospectus  relating thereto
is required to be delivered under the 1933 Act, of the happening of any event as
a result of which the prospectus  included in such  registration  statement,  as
then in effect,  includes  an untrue  statement  of a material  fact or omits to
state a material  fact  required to be stated  therein or  necessary to make the
statements  therein  not  misleading  in the  light  of the  circumstances  then
existing.


                                      -10-


<PAGE>


          (f) Cause the  securities of the Holder to be listed or designated for
trading  on such  securities  exchange  or  automated  quotation  system  as any
securities  of the same class of the Company are then listed or quoted or, if no
such listing or quotation then exists, as reasonably determined by the Company.

          (g) Make documents,  files, books,  records,  officers,  directors and
employees  of the Company  available  to the Holder and  provided  the  Holder's
underwriters,  if any,  shall have agreed to be bound by the  provisions of this
Section 7.5(g), to such underwriters,  and make such other accommodations as are
reasonably  necessary for the Holder and the Holder's  underwriters,  if any, to
perform a due diligence review of the Company; provided,  however, that all such
information  ("Confidential  Information")  will  be kept  confidential  and not
utilized by Holder except as  contemplated  herein and except as required by law
or court order. The term "Confidential Information" does not include information
which (i) is already in possession of such other party (other than that which is
subject to another confidentiality  agreement), (ii) becomes generally available
to the public,  or (iii) becomes  available on a  non-confidential  basis from a
source other than the Company.

          (h) Provide such opinions, certifications,  indemnifications, and take
such other actions, including, without limitation, entering into such agreements
(including underwriting agreements), as are reasonably required and appropriate,
to permit the Holder to make a public  offering  of the  Registrable  Securities
requested to be registered.

     7.6 Furnish Information. The Company's obligation to cause any registration
statement to become effective in connection with distribution of any Registrable
Securities  pursuant to this  Agreement  is  contingent  upon the  Holder,  with
reasonable  promptness,  furnishing  to the Company such  information  regarding
itself,  the  Registrable  Securities  held by it,  and the  intended  method of
disposition of such securities, as is required to effect the registration of the
Registrable Securities.

     7.7 Indemnification. In the event of any registration under this Agreement:

          (a) To the extent  permitted by law, the Company  will  indemnify  and
hold harmless the Holder and its officers,  directors and affiliates  (and their
officers and  directors),  any  underwriter (as defined in the 1933 Act) for the
Holder and each person (and its  officers and  directors),  if any, who controls
the Holder or  underwriter  within the  meaning of the 1933 Act or the 1934 Act,
against any losses, claims,  damages, or liabilities (joint or several) to which
they may become  subject under the 1933 Act, or the 1934 Act or other federal or
state law, insofar as such losses,  claims,  damages, or liabilities (or actions
in  respect  thereof)  arise  out  of or are  based  upon  any of the  following
statements, omissions or violations (collectively a "Violation"): (i) any untrue
statement  or alleged  untrue  statement  of a material  fact  contained in such
registration statement, including any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto, (ii) the omission or

                                      -11-


<PAGE>


alleged omission to state therein 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 (iii) any violation
or alleged  violation  by the Company of the 1933 Act,  the 1934 Act,  any state
securities law or any rule or regulation  promulgated under the 1933 Act, or the
1934 Act or any state  securities  law,  and the Company will pay to the Holder,
underwriter  or  controlling  person,  as incurred,  any legal or other expenses
reasonably  incurred by them in connection with  investigating  or defending any
such loss, claim, damage,  liability,  or action;  provided,  however,  that the
indemnity  agreement contained in this subsection (a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability, or action if such
settlement is effected  without the consent of the Company  (which consent shall
not be unreasonably  withheld),  nor will the Company be liable in any such case
for any such loss,  claim,  damage,  liability,  or action to the extent that it
arises out of or is based upon (1) a Violation which occurs solely as the result
of the written  information  furnished expressly for use in connection with such
registration  by the  Holder,  underwriter  or  controlling  person  or (2) with
respect to the Underwriter and controlling person of such Underwriter (and their
respective officers and directors), a Violation which results from the fact that
there was not sent or given to a person who bought Registrable Securities, at or
prior to the written  confirmation of the sale, a copy of the final  prospectus,
as then amended or supplemented,  if the Company had previously furnished copies
of such prospectus  hereunder and such prospectus  corrected the misstatement or
omission forming the basis of the Violation.

          (b) To the extent permitted by law, the Holder will indemnify and hold
harmless the Company, each of its directors, each of its officers who has signed
the registration statement, each person, if any, who controls the Company within
the meaning of the 1933 Act, any underwriter  and any controlling  person of any
such  underwriter  or other  holder,  against any losses,  claims,  damages,  or
liabilities  (joint or several) to which any of the foregoing persons may become
subject,  under the 1933 Act,  or the 1934 Act or other  federal  or state  law,
insofar as such losses,  claims,  damages,  or liabilities (or action in respect
thereto)  arise  out of or are  based  upon any  Violation,  in each case to the
extent (and only to the extent) that such Violation occurs solely as a result of
the written information  furnished by the Holder expressly for use in connection
with such  registration;  and such Holder will pay,  as  incurred,  any legal or
other  expenses  reasonably  incurred by any person  intended to be  indemnified
pursuant to this subsection (b), in connection with  investigating  or defending
any such loss, claim, damage, liability, or action; provided,  however, that the
Holder's  liability  pursuant  to this  Section  7.7(b)  shall be limited to the
amount  of the  net  proceeds  received  by the  Holder  from  the  sale  of the
Registrable  Securities  sold by it, and  further  provided  that the  indemnity
agreement  contained  in this  subsection  (b) does not apply to amounts paid in
settlement  of any  such  loss,  claim,  damage,  liability  or  action  if such
settlement  is effected  without the consent of the Holder,  which consent shall
not be unreasonably withheld.


                                      -12-


<PAGE>


          (c) Promptly after receipt by an indemnified  party under this Section
7.7 of notice of the  commencement  of any action  (including  any  governmental
action),  such  indemnified  party will, if a claim in respect  thereof is to be
made  against any  indemnifying  party under this  Section  7.7,  deliver to the
indemnifying  party a written notice of the  commencement of such action and the
indemnifying party will have the right to participate in, and, to the extent the
indemnifying  party so  desires,  jointly  with  any  other  indemnifying  party
similarly  noticed,   to  assume  the  defense  thereof  with  counsel  mutually
satisfactory  to the  parties;  provided,  however,  that an  indemnified  party
(together with all other  indemnified  parties which may be represented  without
conflict by one  counsel)  will have the right to retain one  separate  counsel,
with  the  fees  and  expenses  to  be  paid  by  the  indemnifying   party,  if
representation  of  the  indemnified  party  by  the  counsel  retained  by  the
indemnifying  party would be inappropriate due to actual or potential  differing
interests  between the indemnified party and any other party represented by such
counsel in the same proceeding.  If the indemnifying  party shall fail to defend
the action,  or conducts a defense which is not reasonably  adequate in light of
the  circumstances,  the indemnified party may conduct its own defense and shall
be  entitled  to  reimbursement  for the costs of such  defense.  The failure to
deliver written notice to the indemnifying party within a reasonable time of the
commencement of any such action shall not relieve such indemnifying party of any
liability  to the  indemnified  party under this Section 7, except to the extent
that the  indemnifying  party is  materially  prejudiced  by such  failure.  The
omission so to deliver written notice to the indemnifying party does not relieve
it of any liability  that it may have to any  indemnified  party  otherwise than
under this Section 7. No indemnifying party under this Agreement will enter into
any  settlement or consent to any entry of judgment which does not include as an
unconditional  term  thereof  the giving by the  claimant  or  plaintiff  to the
indemnified  party of a release  from all  liability in respect of such claim or
litigation.

          (d) If the indemnification provided for in this Section 7 is held by a
court of competent  jurisdiction to be unavailable to an indemnified party or is
insufficient  to  indemnify  an  indemnified  party  with  respect  to any loss,
liability,  claim, damage, or expense referred to therein, then the indemnifying
party,  in  lieu  of  or in  addition  to,  as  appropriate,  indemnifying  such
indemnified  party  hereunder,  will contribute to the amount paid or payable by
such indemnified party as a result of such loss,  liability,  claim,  damage, or
expense in such  proportion as is  appropriate  to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in  connection  with the  statements  or omissions  that  resulted in such loss,
liability,  claim,  damage,  or expense as well as any other relevant  equitable
considerations.  The  relative  fault  of  the  indemnifying  party  and  of the
indemnified  party will be  determined  by  reference  to,  among other  things,
whether  the  untrue or  alleged  untrue  statement  of a  material  fact or the
omission  to state a  material  fact  relates  to  information  supplied  by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge,  access to  information,  and  opportunity to correct or prevent such

                                      -13-


<PAGE>


statement  or  omission.  The  obligation  of the Holder to make a  contribution
pursuant to this Section 7.7(d) shall be limited to the net proceeds received by
the Holder  from the sale of the  Registrable  Securities  sold by it,  less any
amounts paid pursuant to Section 7.7(b).

          (e) The obligations of the Company and the Holder under this Section 7
will survive the  completion  of any  offering of  Registrable  Securities  in a
registration statement under this Agreement, and otherwise.

     7.8 Expenses of Registration.  All expenses incurred in connection with any
registration,  qualification  or  compliance  pursuant  to  Section  7  of  this
Agreement,   including,   without  limitation,  all  registration,   filing  and
qualification fees, printing expenses, fees and disbursements of counsel for the
Company and  expenses of any special  audits  incidental  to or required by such
registration,  qualification or compliance will be borne by the Company,  except
that  the  Company  will  not  be  required  to  pay  underwriters'   discounts,
commissions,  or stock transfer taxes relating to the Registrable  Securities or
the fees and disbursements of counsel to the Holder,  other than as set forth in
this Section 7.

     7.9  Amendments.  Any term of this  Section 7 may be amended  only with the
written  consent of the Company and the holders of a majority of the Registrable
Securities  then  outstanding.  Any amendment  effected in accordance  with this
paragraph will be binding upon each holder of any  Registrable  Securities  then
outstanding,  each future  holder of all such  Registrable  Securities,  and the
Company.

8.  Miscellaneous.  The Company shall pay all expenses and other charges payable
in connection  with the  preparation,  issuance and delivery of this Warrant and
all  substitute  Warrants  other than as set forth in this Section 8. The Holder
shall  pay  all  taxes  (other  than  any  issuance  taxes,  including,  without
limitation,  documentary  stamp  taxes,  transfer  taxes and other  governmental
charges,  which shall be paid by the Company) in  connection  with such issuance
and delivery of the Warrants and the Shares.

          The  Company  shall  maintain,  at the office or agency of the Company
maintained  by the  Company,  books for the  registration  and  transfer  of the
Warrant.

9.  Reservation  of Shares.  The Company  will use its best efforts to amend its
Articles of Incorporation  to increase the number of authorized  Common Stock so
that the  Company  will be able to reserve  all shares  that may be  exercisable
under this Warrant. As soon as any shares of Common Stock become available to be
reserved for issuance under this Warrant (the Company agreeing to use all shares
of Common Stock that are no longer subject to the Series B Preferred Stock or 6%
Convertible Debentures upon any repurchase, termination, cancellation, amendment
or  modification  thereof)  and in any event  upon  approval  and filing of such
amendment to its Articles of Incorporation, the Company will immediately reserve

                                      -14-


<PAGE>



and keep  available,  free from preemptive  rights,  out of the aggregate of its
authorized  but unissued  Common Stock or its authorized and issued Common Stock
held in its  treasury,  solely for the  purpose of  enabling  it to satisfy  any
obligation to issue Shares upon exercise of this Warrant,  the maximum number of
shares of Common Stock which may then be  deliverable  upon the exercise of this
Warrant  and notify the  Holder in writing of such  reservation.  Except for the
issuance of 450,000  shares to John  Liviakis,  the Company will not reserve for
issuance  or issue any shares of Common  Stock to any person  (other  than under
outstanding  options,  warrants or convertible  securities for which shares have
already been reserved) until such time that it has reserved all shares of Common
Stock that may be exercised under this Warrant.

          The Company or, if appointed,  the transfer agent for the Common Stock
(the "Transfer Agent") and every subsequent transfer agent for any shares of the
Company's  capital  stock  issuable  upon the  exercise  of any of the rights of
purchase  aforesaid will be irrevocably  authorized and directed at all times to
reserve such number of authorized  shares as shall be required for such purpose.
The Company will keep a copy of this Warrant on file with the Transfer Agent and
with every  subsequent  transfer  agent for any shares of the Company's  capital
stock  issuable upon the exercise of the rights of purchase  represented by this
Warrant.  The Company will furnish such Transfer  Agent a copy of all notices of
adjustments and certificates  related thereto transmitted to the Holder pursuant
to Section 2.5 hereof.

          The  Company  covenants  that all  Shares  which  may be  issued  upon
exercise of this Warrant will, upon issue, be fully paid, nonassessable, free of
preemptive rights and free from all taxes, liens, charges and security interests
with respect to the issue thereof.

10. Obtaining Stock Exchange Listings. The Company will, from time to time, take
all actions  which may be necessary so that the Shares,  immediately  upon their
issuance  upon the  exercise of this  Warrant,  will be listed on the  principal
securities exchanges and markets within the United States of America, if any, on
which other shares of Common Stock are then listed; provided, however, that this
provision will not be construed to require registration of such Shares except as
otherwise  provided  in this  Agreement  and no listing  will be required to the
extent such listing  would violate  applicable  laws,  regulations  and exchange
regulations.

11.  Adjustment of Number of Shares Issuable and Exercise  Price.  The number of
Shares  issuable  upon the  exercise  of this  Warrant  and the Share  Price are
subject  to  adjustment  from time to time  upon the  occurrence  of the  events
enumerated  in Section 2. For  purposes of this  Warrant,  "Common  Stock" means
shares now or hereafter  authorized  of any class of common stock of the Company
and any  other  stock of the  Company,  however  designated,  that has the right
(subject  to any prior  rights of any  class or  series of  preferred  stock) to
participate in any distribution of the assets or earnings of the Company without
limit as to per share amount.

Attn:  Dean Leavitt


                  Re:      Commitment Letter

Gentlemen:

     Please  be  advised  that in  connection  with the term  sheet  (the  "Term
Sheet"),  dated December 23, 1999 by and between  Commonwealth  Associates  L.P.
("Commonwealth")  and US Wireless Data, Inc. (the  "Company"),  we hereby agree,
subject to the terms and  conditions  as  hereinafter  provided or otherwise set
forth in the Term Sheet to make available to the Company a loan (the "Loan"), in
the  aggregate  principal  amount  of up to  One  Million  Dollars  ($1,000,000)
dollars.

     The Loan will be made in separate tranches (each a "Tranche"), within three
(3) business days of receipt by us in  accordance  with this Letter of a request
for the funding of a Tranche (a "Request Letter") from the Company. Each Request
Letter shall set forth the exact  amount of funds  requested to be loaned in the
particular Tranche and the intended use of the loan proceeds from such Tranche.

     Prior to and as a condition  precedent to funding each  requested  Tranche,
the  Company  shall  provide  to us  (i) a  note  (the  "Note")  executed  by an
authorized officer of the Company evidencing the principal amount of funds to be
provided in the Tranche (in  substantially the form of the initial $195,000 Note
attached  hereto  as  Exhibit  A);  (ii) a  security  agreement  (the  "Security
Agreement") and related  documents  securing the loan evidenced by the Note (the
"Security  Documents"),  executed  by  an  authorized  officer  of  the  Company
(substantially  in the  form of the  Security  Agreement  securing  the  initial
$195,000 Note annexed hereto as Exhibit B); and (iii) evidence  satisfactory  to
us that Dean Leavitt has advanced funds to the Company in a Proportionate Amount



<PAGE>


US Wireless Data, Inc.
         December 30, 1999
         Page 2




to the amount requested in the Request Letter. "Proportionate Amount" shall mean
the product obtained when the amount of the requested Tranche is multiplied by a
fraction, the numerator of which is 100 and the denominator of which is 805.

     Notwithstanding  anything to the contrary provided herein or elsewhere,  we
shall have no  obligation  to fund a Tranche if at the time a Request  Letter is
received  by us and prior to when the funds  requested  in the Tranche are sent,
one or more of the following events shall have occurred:

     1. Dean Leavitt is no longer the President,  Chief Executive  Officer and a
Director of the Company or is unable to effectively act in the capacity required
to perform the required functions of such positions; or

     2.  The   commencement  by  or  against  the  Company  of  any  bankruptcy,
reorganization,   debt  arrangement  or  other  case  or  proceeding  under  any
bankruptcy or insolvency  law, the  appointment of a trustee,  receiver or other
custodian for the Company or any of its assets, the making of any assignment for
the  benefit  of  creditors  or the  taking  of any  corporate  or other  action
authorizing or initiating any of the foregoing; or

     3. The  Company  shall  have been  unable  to enter  into an  agreement  to
convert,  modify or  purchase  the  Company's  Series B  Preferred  Stock and 6%
Convertible  Debentures  on terms and  conditions  acceptable  to us in our sole
discretion.

     Notwithstanding  anything to the contrary provided herein or elsewhere,  we
may in our sole  discretion  permit a person other than us, which person must be
reasonably  acceptable  to the  Company,  to fund a  portion  of the Loan to the
Company  requested  pursuant to a Request  Letter for all or a portion of one or
more Tranches on the terms and conditions provided herein, and the Company shall
provide to any such person an executed Note  evidencing the principal  amount of
funds provided in such Tranche and the requested  Security  Documents,  provided
that such  documents may be modified as  appropriate  to reflect prior  security
interests of prior  Tranches.  The Company agrees that any employee,  partner or
shareholder of Commonwealth  or any of its affiliates are reasonably  acceptable
for purposes of this Commitment Letter.

     This  Agreement  shall be governed by and construed in accordance  with the
internal  laws of the State of New York without  regard to the conflicts of laws
principles thereof.  The parties hereto hereby agree that any suit or proceeding
arising directly and/or  indirectly  pursuant to or under this instrument or the
consummation of the transactions contemplated hereby, shall be brought solely in
a federal or state court  located in the City,  County and State of New York. By
its execution hereof,  the parties hereby covenant and irrevocably submit to the
in personam  jurisdiction  of the federal and state courts  located in the City,
County and State of New York and agree that any  process in any such  action may
be served upon any of them  personally,  or by certified mail or registered mail
upon them or their agent, return receipt requested, with the same full force and
effect as if personally  served upon them in New York City.  The parties  hereto
waive any claim that any such  jurisdiction  is not a  convenient  forum for any
such suit or proceeding and any defense or lack of in personam jurisdiction with
respect  thereto.  In the  event of any such  action  or  proceeding,  the party
prevailing  therein  shall be entitled to payment from the other party hereto of
its  reasonable   counsel  fees  and   disbursements  in  an  amount  judicially
determined.

collateral (the "Collateral"),  all as more particularly  described and provided
therein,  and is entitled to the benefits thereof.  The Security Agreement,  the

granted  liens on assets of the  Company  are  collectively  referred  to as the
"Security Documents."

     This Note is being issued  pursuant to a letter dated  December 30, 1999 by
and between the Company  and the Payee (the  "Commitment  Letter"),  pursuant to
which,  as  provided  in the  Commitment  Letter  the  Holder has agreed to make
available  to the Company up to  $1,000,000  of bridge  financing  (the  "Bridge
Financing").  Capitalized  terms  used but not  defined  herein  shall  have the
meaning ascribed to such terms in the Commitment Letter.

     4.  Conversion  Into Private  Placement  Units.  During the period that the

Intent dated December 23, 1999 by and between the Company and Commonwealth  (the
"Term  Sheet"),  the Company  completes a closing of a minimum of  $2,500,000 of
gross proceeds through  Commonwealth of units (the "Private  Placement  Units"),
the  holders  of this Note and of all other  notes  issued by the  Company  (the
"Other  Notes"),  in the Bridge  Financing as  contemplated  by the Term Sheet),
shall,  at their sole option,  be entitled to convert all or any portion of this
Note or the other Notes into the Private  Placement Units on the identical terms
and  conditions  as  investors  in the Private  Placement  purchase  the Private
Placement Units. In the event of such election,  all amounts due under this Note
and the Other Notes sold in the Bridge  Financing so converted  into the Private
Placement  Units  shall be  counted  as part of the  proceeds  raised in Private
Placement.

     5. The Bridge Warrants.  In consideration for the $195,000 loan represented
by this Note and the  Commitment to lend up to another  $805,000 as set forth in
the Commitment Letter, the Company shall issue to the Payee  simultaneously with
the  Payee's  execution  of this  Note a seven  (7)  year  warrant  to  purchase
13,636,363  shares of Common Stock,  at an exercise price of $.01 per share upon
the  terms  and  subject  to the  limitations  contained  therein  (the  "Bridge

Participation  Agreement  dated December 30, 1999 (the  "Economic  Participation

     6. Prepayment. This Note may be prepaid without penalty in whole or in part
at any time.

     7. Computation of Interest.

          A. Base Interest Rate.  Subject to  subsections  4B and 4C below,  the
outstanding  Principal  Amount  shall  bear  interest  at the rate of eight (8%)
percent per annum.

          B.  Penalty  Interest.  In the  event  the Note is not  repaid  on the
Maturity Date, the rate of interest  applicable to the unpaid  Principal  Amount
shall be adjusted to thirteen  (13%)  percent per annum from the date of default
until repayment;  provided,  that in no event shall the interest rate exceed the
Maximum Rate provided in Section 4C below.

          C. Maximum Rate. In the event that it is determined  that New York law
is not applicable to the  indebtedness  evidenced by this Note or that under New
York law ("Applicable  Usury Laws"),  the interest,  charges and fees payable by
the Company in connection  herewith or in connection  with any other document or
instrument  executed and  delivered in connection  herewith  cause the effective
interest rate  applicable to the  indebtedness  evidenced by this Note to exceed
the maximum rate allowed by law (the "Maximum  Rate"),  then such interest shall
be recalculated  for the period in question and any excess over the Maximum Rate
paid with respect to such period shall be credited, without further agreement or
notice, to the Principal Amount outstanding  hereunder to reduce said balance by
such  amount  with  the  same  force  and  effect  as  though  the  Company  had
specifically  designated  such extra sums to be so applied to principal  and the
Payee had agreed to accept such extra  payment(s) as a premium-free  prepayment.
All such deemed prepayments shall be applied to the principal balance payable at
maturity.

     8. Covenants of Company.

          A. Affirmative  Covenants.  The Company  covenants and agrees that, so
long as this Note shall be  outstanding,  it will  perform the  obligations  set
forth in this Section 5A:

               (i) Taxes and Levies. The Company will promptly pay and discharge
all taxes,  assessments,  and  governmental  charges or levies  imposed upon the
Company or upon its income and profits, or upon any of its property,  before the
same shall become  delinquent,  as well as all claims for labor,  materials  and
supplies which, if unpaid, might become a lien or charge upon such properties or
any part thereof;  provided, however , that the Company shall not be required to
pay and discharge any such tax, assessment, charge, levy or claim so long as the
validity thereof shall be contested in good faith by appropriate proceedings and
the Company shall set aside on its books  adequate  reserves in accordance  with
generally accepted accounting  principles ("GAAP") with respect to any such tax,
assessment, charge, levy or claim so contested;

done all things  reasonably  necessary  to  preserve  and keep in full force and
effect its corporate  existence,  rights and franchises and comply with all laws
applicable  to the Company,  except where the failure to comply would not have a
material adverse effect on the Company;

               (iii)  Maintenance  of  Property.  The Company  will at all times
maintain,  preserve, protect and keep its property used or useful in the conduct
of its business in good repair,  working order and  condition,  and from time to
time  make  all  needful  and  proper  repairs,   renewals,   replacements   and
improvements  thereto  as shall be  reasonably  required  in the  conduct of its
business;

               (iv) Insurance. The Company will, to the extent necessary for the
operation  of  its  business,  keep  adequately  insured  by  financially  sound
reputable  insurers,  all  property  of a character  usually  insured by similar
corporations  and carry such other  insurance  as is usually  carried by similar
corporations;

               (v) Books and  Records.  The Company  will at all times keep true
and correct books,  records and accounts  reflecting all of its business affairs
and  transactions  in accordance with GAAP. Such books and records shall be open
at reasonable times and upon reasonable notice to the inspection of the Payee or
its agents; and

               (vi)  Notice of Certain  Events.  The  Company  will give  prompt
written notice (with a description in reasonable detail) to the Payee of:

                    (a) the  occurrence  of any  Event of  Default  or any event
which, with the giving of notice or the lapse of time, would constitute an Event
of Default; and

                    (b) the delivery of any notice effecting the acceleration of
any   indebtedness   which  singly  or  together  with  any  other   accelerated
indebtedness exceeds $100,000.

          B. Negative Covenants.  The Company covenants and agrees that, so long

          C. Subsidiaries. The Company does not own, directly or indirectly, any
capital stock or other equity  securities of any corporation,  limited liability
company,  partnership or any other entity or have any direct or indirect  equity

          D. Authorization; No Violation.

               (a) The Company has full corporate power and authority  necessary
to enter into this Note, the Commitment Letter, the Bridge Warrant, the Economic
Participation   Agreement  and  the  Security   Documents   (collectively,   the
"Documents"),  and to carry out the transactions  contemplated by the Documents.
The Board of  Directors  of the  Company  has  taken  such  necessary  action to
authorize the execution  and delivery of the Documents and the  consummation  of
the transactions contemplated thereby. The Documents have been duly executed and
delivered  by the Company and are legal,  valid and binding  obligations  of the
Company enforceable against it in accordance with its terms except that (i) such
enforcement may be subject to bankruptcy, insolvency, reorganization, moratorium
or other similar laws now or hereafter in effect  relating to creditors'  rights

the court before which any proceeding therefore may be brought.

               (b) Neither the  execution  and delivery of any of the  Documents
nor the consummation of the transactions  contemplated  thereby will violate any
provision of the articles or  certificate of  incorporation  or by-laws or other
organizational  documents of the Company,  be in conflict  with, or constitute a
default  (or an event  which,  with  notice  or  lapse  of time or  both,  would
constitute a default) under or result in the  termination  of, or accelerate the
performance  required by, or cause the  acceleration of the maturity of any debt
or  obligation  pursuant  to, or result in the  creation  or  imposition  of any
security interest,  lien or other encumbrance upon any property or assets of the
Company, any agreement or commitment to which the Company is a party or by which
the Company is bound or to which the  property  of the  Company is  subject,  or
violate any statute or law or any judgment, decree, order, regulation or rule of
any court or governmental  authority applicable to the Company,  except that the
Company does not currently have sufficient authorized shares for the exercise of
the  Bridge  Warrant  and  the  issuance  of  such  warrant   triggers   certain
antidilution provisions disclosed elsewhere herein.

          E. Financial  Statements.  The Company has heretofore delivered to the
Payee (i) a  balance  sheet of the  Company  as at June 30, in each of the years

obligations  of any nature  (absolute,  accrued,  contingent or  otherwise)  not
otherwise  disclosed herein which are not fully reflected or reserved against in
the Balance  Sheet,  which,  in accordance  with generally  accepted  accounting
principles,  should have been shown or reflected in the Balance Sheet except for
accounts  payable  incurred in the  ordinary  course of  business.  The reserves
reflected in the Balance Sheet are adequate, appropriate and reasonable.

nothing to impair the rights of the Secured Party in the  Equipment.  The Debtor
shall  cause  the  Equipment  to at all times  constitute  and  remain  personal
property.  The  Debtor  will  at all  times  keep  all  Equipment  insured  with
financially  responsible  insurance  companies in favor of the Secured Party, at
the  expense of the  Debtor,  against  such  perils  and in such  amounts as are
customary  for  Persons in the same  general  line of business as the Debtor and
operating in similar geographic  locations and markets. If the Debtor shall fail
to insure the Equipment to the Secured  Party's  satisfaction,  or if the Debtor


                                       -9-

<PAGE>



shall fail so to endorse and deposit all policies or  certificates  with respect
thereto,  the  Secured  Party  shall  have  the  right  (but  shall  be under no
obligation)  to procure such  insurance  and the Debtor  agrees to reimburse the
Secured Party for all costs and expenses of procuring such  insurance,  together
with  interest at a rate per annum equal to 18%. The Secured Party may apply any
proceeds  of such  insurance  when  received by it pursuant to the terms of this
Section 6 or  Section  3(h)  hereof  toward the  payment  of any of the  Secured
Obligations,  whether or not the same shall then be due. The Debtor  retains all
liability and  responsibility in connection with the Equipment and the liability
of the Debtor to pay the  Secured  Obligations  shall in no way be  affected  or
diminished  by reason of the fact that such  Equipment  may be lost,  destroyed,
stolen, damaged or for any reason whatsoever unavailable to the Debtor.

     Section 7. Financing Statements; Documentation; Stamp Taxes.

     (a)  The  Debtor  will,  at  its  own  expense,  make,  execute,   endorse,
acknowledge,  file and/or  deliver to the  Secured  Party from time to time such
lists, descriptions and designations of Inventory,  warehouse receipts, bills of
lading,  documents  of  title,  vouchers,  invoices,   schedules,   confirmatory
assignments, conveyances, financing statements, transfer endorsements, powers of
attorney,  certificates,  reports and other  assurances or instruments  and take
such  further  steps  relating to the  Collateral  and other  property or rights
covered by the security  interest hereby granted,  which the Secured Party deems
appropriate or advisable to perfect,  preserve or protect its security  interest
in  the  Collateral.  The  Debtor  hereby  constitutes  the  Secured  Party  its
attorney-in-fact  to  execute  and file in the name and on behalf of the  Debtor
such additional financing statements as the Secured Party may request, such acts
of such attorney being hereby ratified and confirmed;  such power, being coupled
with an interest, is irrevocable until the Secured Obligations are paid in full.
Further,  to the extent  permitted by applicable law, the Debtor  authorizes the
Secured Party to file any such financing statements without the signature of the
Debtor.  The Debtor will pay all applicable  filing fees and related expenses in
connection with any such financing statements.

     (b) The Debtor agrees to procure,  pay for,  affix to any and all documents
and cancel  any  documentary  tax stamps  required  by and in  accordance  with,
applicable law and the Debtor will indemnify and hold the Secured Party harmless
against any  liability  (including  interest and  penalties)  in respect of such
documentary stamp taxes.

     Section 8. Special Provisions  Concerning Remedies and Sale. In addition to
any rights and remedies now or hereafter granted under applicable law and not by
way of  limitation of any such rights and  remedies,  upon the  occurrence of an
Event of Default and, if prior to the Maturity Date,  Acceleration,  the Secured
Party  shall have all of the rights and  remedies  of a secured  party under the
Uniform Commercial Code as enacted in any applicable jurisdiction in addition to
the rights and remedies  provided herein, in the Note and in any other agreement
executed in connection  with the Note whereby the Debtor has granted any Lien to
the Secured Party. Without in any way limiting the foregoing, upon the giving of
notice to the Debtor of Secured  Party's  intent to pursue any one or all of the
following or any other remedies:

                                      -10-

<PAGE>




     (a)  Upon  the  occurrence  of an Event  of  Default  and,  if prior to the
Maturity Date, Acceleration,  the Secured Party shall have all of the rights and
remedies of a secured party under the Uniform  Commercial Code as enacted in any
applicable  jurisdiction in addition to the rights and remedies provided herein,
in the Note and any other  document  whereby  the Debtor has granted any Lien to
the Secured  Party.  The Secured  Party  shall have the right,  without  further
notice to, or assent by, the Debtor, in the name of the Debtor or in the name of
the Secured Party or otherwise:

          (i)  to  ask  for,  demand,  collect,   receive,   compound  and  give
acquittance for the Receivables or any part thereof;

          (ii) to extend the time of payment of,  compromise or settle for cash,
credit or otherwise, and upon any terms and conditions, any of the Receivables;

          (iii) to endorse the name of the Debtor on any checks, drafts or other
orders or  instruments  for the  payment of moneys  payable to the Debtor  which
shall be issued in respect of any Receivable;

          (iv) to  file  any  claims,  commence,  maintain  or  discontinue  any
actions,  suits or other  proceedings  deemed by the Secured Party  necessary or
advisable for the purpose of collecting or enforcing payment of any Receivable;

          (v) to make  test  verifications  of the  Receivables  or any  portion
thereof,

          (vi) to  notify  any or all  account  debtors  under any or all of the
Receivables  to make  payment  thereof  directly  to the  Secured  Party for the
account of the Secured Party and to require the Debtor to forthwith give similar
notice to the account debtors;

          (vii) to require the Debtor  forthwith  to account for and transmit to
the Secured Party in the same form as received all proceeds (other than physical
property) of  collection  of  Receivables  received by the Debtor and,  until so
transmitted,  to hold the same in trust for the Secured  Party and not commingle
such proceeds with any other funds of the Debtor;

          (viii) to take  possession  of any or all of the  Collateral  and, for
that purpose, to enter, with the aid and assistance of any Person or Persons and
with or without legal process,  any premises where the  Collateral,  or any part
thereof,  are,  or may  be,  placed  or  assembled,  and to  remove  any of such
Collateral;

          (ix) to execute any instrument  and do all other things  necessary and
proper to protect and  preserve and realize  upon the  Collateral  and the other
rights contemplated hereby;

          (x) upon notice to such effect,  to require the Debtor to deliver,  at
the Debtor's  expense,  any or all  Collateral  to the Secured  Party at a place
designated by the Secured Party; and


                                      -11-

<PAGE>



          (xi) without  obligation to resort to other security,  at any time and
from  time to time,  to sell,  re-sell,  assign  and  deliver  all or any of the
Collateral,  in one or more  parcels  at the same or  different  times,  and all
right,  title and  interest,  claim and demand  therein and right of  redemption
thereof,  at  public  or  private  sale,  for cash,  upon  credit or for  future
delivery, and at such price or prices and on such terms as the Secured Party may
determine,  with the  amounts  realized  from any such sale to be applied to the
Secured Obligations in the manner determined by the Secured Party.

     The Debtor hereby agrees that all of the foregoing may be effected  without
demand,  advertisement or notice (except as otherwise  provided herein or as may
be required by law),  all of which  (except as  otherwise  provided)  are hereby
expressly waived, to the extent permitted by law. The Secured Party shall not be
obligated to do any of the acts  hereinabove  authorized,  but in the event that
the Secured  Party  elects to do any such act,  the  Secured  Party shall not be
responsible to the Debtor except for its gross negligence or willful misconduct.

     (b) The Secured Party may take legal  proceedings  for the appointment of a
receiver or receivers  (to which the Secured Party shall be entitled as a matter
of right) to take possession of the Collateral pending the sale thereof pursuant
either to the powers of sale granted by this  Agreement or to a judgment,  order
or decree made in any judicial  proceeding for the  foreclosure or involving the
enforcement  of this  Agreement.  If,  after the  exercise of any or all of such
rights and remedies,  any of the Secured  Obligations  shall remain unpaid,  the
Debtor shall remain liable for any deficiency. After the indefeasible payment in
full of the Secured Obligations, any proceeds of the Collateral received or held
by the Secured Party shall be turned over to the Debtor and the Collateral shall
be reassigned to the Debtor by the Secured Party without recourse to the Secured
Party and without any representations, warranties or agreements of any kind.

     (c) Upon any sale of any of the Collateral, whether made under the power of
sale hereby given or under judgment,  order or decree in any judicial proceeding
for the foreclosure or involving the enforcement of this Agreement:

          (i) the Secured Party may, to the extent permitted by law, bid for and
purchase the property being sold, and upon compliance with the terms of sale may
hold,  retain and possess and dispose of such property in its own absolute right
without further accountability,  and may, in paying the purchase money therefor,
deliver  any Note or claims  for  interest  thereon  and any  other  instruments
evidencing  the Secured  Obligations  or agree to the  satisfaction  of all or a
portion  of the  Secured  Obligations  in lieu of cash in  payment of the amount
which shall be payable thereon,  and the Note and such instruments,  in case the
amounts so payable  thereon shall be less than the amount due thereon,  shall be
returned to the Secured Party after being appropriately  stamped to show partial
payment;

          (ii) the  Secured  Party  may make and  deliver  to the  purchaser  or
purchasers a good and sufficient deed, bill of sale and instrument of assignment
and transfer of the property sold;

          (iii) the Secured Party is hereby  irrevocably  appointed the true and
lawful  attorney-in-fact  of the  Debtor  in its  name  and  stead,  to make all
necessary deeds, bills of sale and instruments of assignment and transfer of the
property thus sold and for such other  purposes as are necessary or desirable to
effectuate the provisions  (including,  without  limitation,  this Section 8) of

                                      -12-

<PAGE>



this  Agreement,  and for that purpose it may execute and deliver all  necessary
deeds,  bills  of sale and  instruments  of  assignment  and  transfer,  and may
substitute one or more Persons with like power,  the Debtor hereby ratifying and
confirming all that its said attorney, or such substitute or substitutes,  shall
lawfully do by virtue hereof; but if so requested by the Secured Party or by any
purchaser,  the Debtor  shall  ratify and  confirm  any such sale or transfer by
executing and delivering to the Secured Party or to such purchaser all property,
deeds, bills of sale, instruments or assignment and transfer and releases as may
be designated in any such request;

          (iv) all right, title, interest,  claim and demand whatsoever,  either
at law or in equity or  otherwise,  of the Debtor of, in and to the  property so
sold shall be  divested;  such sale shall be a perpetual  bar both at law and in
equity against the Debtor,  its successors and assigns,  and against any and all
Persons  claiming or who may claim the property  sold or any part thereof  from,
through or under the Debtor, its successors or assigns;

          (v) the receipt of the Secured Party or of the officer  thereof making
such sale shall be a sufficient discharge to the purchaser or purchasers at such
sale for his or their purchase money, and such purchaser or purchasers,  and his
or their  assigns or  personal  representatives,  shall not,  after  paying such
purchase  money and  receiving  such  receipt  of the  Secured  Party or of such
officer therefor, be obliged to see to the application of such purchase money or
be in any  way  answerable  for  any  loss,  misapplication  or  non-application
thereof;  and (vi) to the extent that it may  lawfully do so, and subject to any
legal  requirement  that the  Secured  Party  act in a  commercially  reasonable
manner, the Debtor agrees that it will not at any time insist upon, or plead, or
in any  manner  whatsoever  claim or take  the  benefit  or  advantage  of,  any
appraisement,  valuation,  stay,  extension  or  redemption  laws,  or  any  law
permitting  it to direct the order in which the  Collateral  or any part thereof
shall be sold, now or at any time hereafter in force,  which may delay,  prevent
or otherwise  affect the performance or enforcement of this Agreement,  the Note
or any other  agreement  executed in connection with the Note whereby the Debtor
has granted  any Lien to the  Secured  Party,  and the Debtor  hereby  expressly
waives all benefit or advantage of any such laws and covenants  that it will not
hinder,  delay or impede the  execution of any power granted or delegated to the
Secured  Party in this  Agreement,  but will suffer and permit the  execution of
every such power as though no such laws were in force.  In the event of any sale
of  Collateral  pursuant to this Section,  the Secured Party shall,  at least 10
days before such sale,  give the Debtor  written,  telecopied or telex notice of
its intention to sell.

     Section 9.  Application of Moneys.

     (a) Except as otherwise  provided  herein or in the Note,  all moneys which
the Secured Party shall receive, in accordance with the provisions hereof, shall
be applied  (to the extent  thereof)  in the  following  manner:  First,  to the
payment of all costs and expenses  reasonably  incurred in  connection  with the
administration and enforcement of, or the preservation of any rights under, this
Agreement or any of the  reasonable  expenses and  disbursements  of the Secured
Party (including,  without limitation, the fees and disbursements of its counsel
and agents);  Second, to the payment of all Secured  Obligations  arising out of
the Note in accordance with the terms of the Note and, if not therein  provided,
in such order as the Secured Party may determine;  and Third,  to the payment of
all other Secured Obligations in such order as the Secured Party may determine.

                                      -13-

     (b) If after  applying any amounts  which the Secured Party has received in
respect of the Collateral  any of the Secured  Obligations  remain  unpaid,  the
Debtor shall continue to be liable for any deficiency, together with interest.

     Section 10. Fees and Expenses, etc. Any and all fees, costs and expenses of
whatever kind or nature,  including but not limited to the reasonable attorneys'

collection,  administration  or enforcement of its rights under this  Agreement,
the filing or  recording of any  documents  (including  all taxes in  connection
therewith)  in public  offices,  the payment or discharge of any taxes,  counsel
fees,  maintenance  fees,  fees and other costs relating to the  encumbrances or
otherwise protecting, maintaining, preserving the Collateral, or in defending or
prosecuting  any  actions  or  proceedings  arising  out  of or  related  to the
Collateral,  shall be borne  and paid by the  Debtor  on  written  demand by the
Secured  Party and until so paid shall be added to the  principal  amount of the
Secured Obligations and shall bear interest at a rate per annum equal to 18%. In
addition, the Debtor will pay, and indemnify and hold the Secured Party harmless
from  and  against,  any  and  all  liabilities,  obligations,  losses,  damages
penalties,  actions,  judgments,  suits, costs, expenses or disbursements of any
kind or nature  whatsoever  with respect to the Collateral,  including  (without
limitation)  claims of patent or trademark  infringement and any claim of unfair
competition or anti-trust violation.

next-business-day delivery.

     (b) No delay  on the part of the  Secured  Party in  exercising  any of its
rights, remedies,  powers and privileges hereunder or partial or single exercise
thereof,  shall constitute a waiver thereof. None of the terms and conditions of
this  Agreement  may be  changed,  waived,  modified  or  varied  in any  manner
whatsoever unless in writing duly signed by the Debtor and the Secured Party. No
notice to or demand on the  Debtor in any case shall  entitle  the Debtor to any

     (c) The obligations of the Debtor  hereunder shall remain in full force and
effect  without  regard to, and shall not be  impaired  by, (i) any  bankruptcy,
insolvency, reorganization,  arrangement, readjustment, composition, liquidation
or the like of the Debtor; (ii) any exercise or non-exercise,  or any waiver of,
any right,  remedy,  power or  privilege  under or in respect of the Note,  this
Agreement or any other  agreement  executed in connection  with the Note whereby
the Debtor has  granted  any Lien to the  Secured  Party or any other  agreement
executed in connection with any of the foregoing, the Secured Obligations or any
security  for any of the  Secured  Obligations;  or (iii)  any  amendment  to or
modification  of any of the  foregoing;  whether  or not the  Debtor  shall have
notice or  knowledge  of any of the  foregoing.  The rights and  remedies of the
Secured Party herein  provided are cumulative and not exclusive of any rights or
remedies which the Secured Party would otherwise have.

     (d) This Agreement  shall be binding upon the Debtor and its successors and
assigns and shall inure to the benefit of the Secured  Party and its  successors

All  agreements,  representations  and warranties  made herein shall survive the
execution and delivery of this Agreement.

     (e) The descriptive  headings of the several sections of this Agreement are
inserted  for  convenience  only and shall not in any way affect the  meaning or
construction of any provision of this Agreement.

any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such  prohibition  or  unenforceability   without   invalidating  the  remaining
provisions  hereof,  and  any  such  prohibition  or   unenforceability  in  any
jurisdiction shall not invalidate or render  unenforceable such provision in any
other jurisdiction.

     (g) All  rights,  remedies  and powers  provided by this  Agreement  may be
exercised  only to the extent  that the  exercise  thereof  does not violate any
applicable  provision  of law,  and the  provisions  hereof are  intended  to be
subject to all  applicable  mandatory  provisions of law that may be controlling
and to be  limited  to the extent  necessary  so that they will not render  this
Agreement  invalid,  unenforceable  in  whole or in part or not  entitled  to be
recorded, registered or filed under the provisions of any applicable law.

     (h) This Agreement and the rights and obligations of the parties  hereunder
shall be construed in  accordance  with and be governed by the laws of the State
of New York except to the extent that matters of title, or creation,  perfection
and priority of the security  interests  created hereby, or procedural issues of
foreclosure  are  required  to be governed by the laws of the state in which the
Collateral,   or  part  thereof,  is  located.   EACH  PARTY  HERETO  KNOWINGLY,
VOLUNTARILY AND  INTENTIONALLY  WAIVES ANY AND ALL RIGHTS IT MAY HAVE TO A TRIAL

                        ECONOMIC PARTICIPATION AGREEMENT

     This Economic Participation  Agreement (the "Agreement") dated December 30,
1999 is made by and between U.S.  Wireless  Data,  Inc., a Colorado  corporation
(the "Company") and ComVest Capital Management LLC ("ComVest").

                              W I T N E S S E T H:

     WHEREAS, ComVest is concurrently herewith making available to the Company a
secured loan (the "Loan") in an amount up to $1.0 million,  which amount will be
funded  $195,000 on the date  hereof and the  balance  may be borrowed  upon the
satisfaction or waiver of certain conditions; and

     WHEREAS,  as an  inducement  for  ComVest to make the Loan the  Company has
agreed to issue  warrants  (the  "Warrant")  to ComVest to  purchase  13,636,363
shares; and

     WHEREAS,  the Company does not have sufficient  authorized shares of Common
Stock as would be  required  to be  reserved  under the  Warrant  to enable  the
Warrant to be exercised in full; and

     WHEREAS,  the Company's Board of Directors will approve as soon as possible
an amendment (the "Amendment") to the Company's  Certificate of Incorporation to
increase  the number of  authorized  shares of Common Stock so that the Company,
among other things,  will be able to reserve all shares that may be  exercisable
under the  Warrants and the Company has agreed to use its best efforts to obtain
shareholder approval of the Amendment; and

     WHEREAS,  the Company is entering into this  Agreement to grant ComVest the
economic equivalent of ownership of those shares of Common Stock as to which the
Warrant is not then exercisable; and

     WHEREAS,  once the Company has obtained the requisite  shareholder approval
for the Amendment and has amended its Certificate of Incorporation thereby, this
Agreement  shall be  cancelled in  consideration  of the Company  reserving  for
issuance  under the  Warrant  sufficient  shares of Common  Stock  such that the
Warrant may be exercised in full.

     NOW, THEREFORE,  for and in consideration of ten dollars and other good and
valuable  consideration,   including  the  premises,   promises,  covenants  and
agreements  made  herein,  the  receipt  and  sufficiency  of which  are  hereby
acknowledged, the parties hereto, intending to be legally bound, hereby agree as
follows:

          1. Economic Participation. Upon any sale, liquidation, dividend (other
     than  mandatory  dividends  payable under the Company's  Series B Preferred
     Stock  as  in   effect   as  the  date   hereof),   distribution,   merger,
     consolidation,  restructuring,  reorganization or other similar transaction
     involving the Company, or upon a sale, lease, license or transfer of all or
     at least a majority of the assets of the Company, or if any person or group
     (as  defined in  Section  13 of the  Securities  Exchange  Act of 1934,  as
     amended),  acquires  or receives  any shares of Common  Stock so that after
     such  acquisition  or receipt such person or group owns at least a majority
     of the  outstanding  shares of Common Stock in each case in one or a series
     of  transactions,  the Company will pay (in cash or at ComVest's  option if
     applicable   in  the  form  of   consideration   received  by  such  common
     shareholder)  to ComVest an amount  equal to the  product of (A) the amount
     paid or received by a common  shareholder of the Company in respect of each
     share held in connection  with the  transaction  triggering  the payment to
     ComVest  and (B) the  Adjusted  Shares.  For  purposes  of this  Agreement,
     "Adjusted Shares" shall mean 13,636,363 shares of Common Stock which amount

     shall be  decreased by (i) the  aggregate  number of shares of Common Stock
     hereafter  reserved for issuance by the Company under the Warrant (adjusted
     for any  adjustments  in the number of shares  subject to the  Warrant) and
     (ii)  6,818,182  shares  (which  number  shall be reduced by 1 for each two
     shares of Common Stock  hereafter  reserved for issuance  under the Warrant
     and further proportionately adjusted to take into effect any changes to the
     shares of Common Stock subject to the Warrant) in the event of a Forfeiture
     Event as defined in the Warrant.

          2. Termination of This Agreement. At such time as the number of shares
     of Common Stock that are reserved for issuance upon exercise of the Warrant
     are  sufficient  to allow the  Warrant  to be  exercised  in full (with all
     adjustments  as may be made  pursuant  to the terms of the  Warrant),  this
     Agreement shall automatically terminate,  unless ComVest shall have already
     exercised its right to liquidated  damages pursuant to Section 3 hereof, in
     which event the  termination of this Agreement shall be governed by Section
     3.

          3.  Liquidated  Damages.  If  this  Agreement  should  not  have  been
     automatically  terminated  as  contemplated  by Section 2 hereof within 120
     days of the date of this  Agreement,  then the Company shall pay to ComVest
     on such 120th day a nonconversion  fee of $500,000 and, in addition,  until
     such time as this  Agreement  is  terminated  as provided in such  section,
     ComVest may elect to receive in cash in  consideration  of  canceling  this
     Agreement  the  greater of (A) $2.0  million or (B) the  product of (1) the
     Adjusted  Shares and (2) the  remainder of (x) the closing  asking price of
     the Common  Stock on the last trading date prior to the exercise by ComVest
     of its liquidation  right and (y) $0.01.  ComVest may exercise its right to
     receive a liquidated  damage  payment by delivering a written notice to the
     Company by facsimile transmission, by hand, by overnight courier or by U.S.
     mail and such  notice  will be deemed  received  by the Company on the date
     sent by  ComVest  unless  the  Company  can  thereafter  prove no  delivery
     thereafter actually occurred.

          4.  Complete  Agreement.   This  Agreement  constitutes  the  complete
     understanding  among the parties  with  respect to its  subject  matter and
     prior  agreements  and  understandings  among any of the parties hereto are
     hereby superseded and terminated and shall have no further force or effect.

          5. Section Headings.  The section headings contained in this Agreement
     are for reference purposes only and shall not affect in any way the meaning
     or interpretation of this Agreement.

          6.  Successors and Assigns.  All of the terms of this Agreement  shall
     inure to the  benefit  of and  shall be  binding  upon the  successors  and
     assigns of the parties hereto except that the Company may not assign any of
     its obligations hereunder.

          7. Governing  Law. This Agreement  shall be governed by, and construed
     and enforced in accordance with the laws of the State of New York,  without
     giving effect to the provisions,  policies or principles thereof respecting
     conflict or choice of laws.

          8.  Modification;  Amendment.  Except as  otherwise  provided  herein,
     neither this Agreement nor any provision  hereof can be modified,  amended,
     changed, discharged or terminated except by an instrument in writing signed
     by the parties hereto.

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

          10.  Severability.  If at any  time  subsequent  to the  date  of this
     Agreement,  any provision of this  Agreement  shall be held by any court of
     competent jurisdiction to be illegal, void or unenforceable, such provision
     shall be of no force or effect but the  illegality or  enforceable  of such
     provision  shall have no effect  upon or impair the  enforceability  of any
     other provision.

         Re:      Advancement of Funds

Gentlemen:

     Reference is made to that certain Commitment Letter dated December 30, 1999
(the "Letter")  between  ComVest  Capital  Management LLC  ("ComVest")  and U.S.
Wireless  Data,  Inc. (the  "Company").  Capitalized  terms used herein  without
definition are used as defined or referred to in the Letter.

     This  letter is to  confirm  that I, as a lender,  will  subject to ComVest
first having funded $195,000 under the Letter, advance funds to the Company in a
proportionate  amount to that funded to the  Company by ComVest  pursuant to the
Letter.  For each $1 advanced by ComVest after such initial $195,000 is advanced
I will advance a fraction of such dollar,  the numerator of which is 100 and the
denominator of which is 805.

                                                 Sincerely,


                                                 /s/ Dean Leavitt
                                                 Dean Leavitt
