                                WARRANT AGREEMENT

                                  FOR UNITS OF

                            U.S. WIRELESS DATA, INC.

Warrant No. ___

     THIS  CERTIFIES  that,  for value  received,  Peter J.  Solomon  Securities
Company Limited, 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,  6.4 Units of
the Company.  Each Unit initially consists of (i) 10,000 shares of the Company's
Series C Convertible Preferred Stock (the "Shares"), each Share convertible into
shares of the Company's  common stock,  no par value (the "Common  Stock"),  and
(ii) seven-year warrants (the "Unit Warrants") to purchase a number of shares of
Common Stock equal to 25% of the number of shares of Common Stock into which the
Shares are convertible. The Shares and Unit Warrants underlying this Warrant are
identical  to the  shares  and unit  warrants  (the  "Investor  Shares"  and the
"Investor  Warrants,"  respectively)  included in the Units sold pursuant to the
Company's Confidential Private Placement Memorandum, dated February 14, 2000, as
amended.  The Investor  Shares and the Investor  Warrants are subject to call as
provided therein and, if this Warrant is exercised after the date that such call
is given (the "Call Date"),  it shall only be exercisable for Common Stock.  The
purchase price for each Unit is one hundred  thousand  dollars  ($100,000)  (the
"Exercise Price"),  provided that if the Holder elects,  after the Call Date, to
receive the Common  Stock which would have been  issuable  upon  exercise of the
Unit  Warrants,  the Exercise Price shall be increased by an amount equal to the
exercise price of such Unit Warrants (the "Underlying  Warrant Exercise Price").
Securities issuable upon exercise of this Warrant 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.

(b) 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  ___________,  2007,  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 Exercise  Price  multiplied by the number of Units as to which this
Warrant is then being  exercised or, if this Warrant is exercised after the Call
Date,  by payment of an amount  equal to the number of shares of Common Stock as
to which this Warrant is being issued multiplied by the Post-Call Exercise Price
(as defined below).  Any transfer of Units obtained by the Holder in exercise of
this Warrant is subject to the  requirement  that such  securities be registered
under the  Securities  Act of 1933, as amended (the "1933 Act"),  and applicable
state securities laws or exempt from registration under such laws. The Holder of
this  Warrant  shall be deemed to be the holder of the Units,  or, if  exercised
after the Call Date,  Common  Stock,  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 Units or shares of Common
Stock 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 Units or Common Stock determined as of the date of delivery.

(c) All or any  portion  of the  Exercise  Price  may be  paid  by  surrendering
Warrants  effected by presentation  and surrender of this Warrant to the Company
with a  Cashless  Exercise  Form  annexed  hereto  duly  executed  (a  "Cashless
Exercise").  Such  presentation  and  surrender  shall be deemed a waiver of the
Holder's  obligation to pay all or any portion of the aggregate  Exercise Price.
In the event of a Cashless  Exercise,  the Holder shall exchange its Warrant for
that number of shares of Common Stock  determined by  multiplying  the number of
Shares for which the Holder desires to exercise this Warrant by a fraction,  the
numerator of which shall be the difference between the then current market price
per share of the Common Stock and the Exercise  Price,  and the  denominator  of
which shall be the then  current  market  price per share of Common  Stock.  For
purposes of any  computation  under this Section 1(b),  the then current  market
price per share of Common  Stock at any date  shall be deemed to be the  average
for the ten consecutive business days immediately prior to the Cashless Exercise
of the  daily  closing  prices of the  Common  Stock on the  principal  national

                                        2

<PAGE>

securities  exchange on which the Common Stock is admitted to trading or listed,
or if not listed or admitted to trading on any such exchange, the closing prices
as reported by the Nadaq  National  Market,  or if not then listed on the Nasdaq
National  Market,  the average of the highest  reported bid and lowest  reported
asked prices as reported by the National Association of Securities Dealers, Inc.
Automated  Quotations System ("Nasdaq") or if not then publicly traded, the fair
market price of the Common Stock as  determined by the Board of Directors of the
Company.

(d) 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 Units
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
Units.  Upon any exercise and surrender of this Warrant,  the Company will issue
and  deliver  to the Holder a  certificate  or  certificates  in the name of the
Holder  for the  number of Shares to which the Holder  shall be  entitled  and a
certificate  representing  the Unit  Warrants,  or, if exercised  after the Call
Date,  the shares of Common Stock,  to which the Holder shall be entitled or the
proportionate part thereof if this Warrant is exercised in part, pursuant to the
provisions of this Warrant.

2.   Adjustments.

     2.1 The Holder of the Warrant shall  receive upon exercise  hereof prior to
the Call Date Shares and Unit Warrants that will reflect all adjustments to such
securities as would have occurred from the date of this Warrant through the date
of exercise of the Warrant and which shall be identical  to Investor  Shares and
Investor Warrants. For purposes of clarity, the Holder of the Warrant,  whenever
exercised prior to the Call Date, shall have the right to receive that amount of
securities  of the Company  had the Holder  exercised  this  Warrant on the date
hereof and  received  the  benefit of all  adjustments  (for  anti-dilution,  or
changes  in  capitalization,  or a merger  or other  transaction  effecting  the
capitalization of the Company) to such securities as if the Holder had held such
securities  from the date hereof  until the date of  exercise  of this  Warrant.
After the Call Date, the Holder of this Warrant shall be entitled to receive the
number of shares of Common Stock which such Holder would have  received had such
Holder exercised this Warrant and the Unit Warrants in full immediately prior to
the Call Date,  as adjusted  equitably for any stock  splits,  stock  dividends,
mergers or  recapitalization  occurring after the Call Date at an exercise price
equal to the conversion or exercise price, as the case may be, of the Shares and
Unit  Warrants  as of the Call Date,  as  appropriately  adjusted  for any stock
dividends,  mergers or recapitalization occurring after the Call Date. By way of
illustration,  if this Warrant was initially  exercisable for one Unit and if on

                                        3

<PAGE>

the Call Date one unit consisted of 10,000 Shares convertible into 66,666 shares
of Common Stock at $1.50 per share and Warrants exercisable for 25% of 66,666 at
$1.50 per share and  subsequent to the Call Date the Company  declared a 2-for-1
stock split,  the Holder  would be entitle to exercise  this Warrant for 166,665
shares of Common Stock at $.75 per share (representing 133,332 shares in respect
of the Shares included in the Unit originally  underlying the Warrant and 33,333
shares of Common  Stock in respect  of the Unit  Warrants  included  in the Unit
originally underlying the Warrant).

     2.2  Notice of  Adjustments.  Upon the  occurrence  of each  adjustment  or
readjustment  of the Units  pursuant to Section  2.1, the Company at its expense
will promptly  compute such adjustment or readjustment 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 to
the Holder of this  Warrant at the  address of such Holder as shown on the books
of the Company.

     2.3 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;

          (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,  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

                                        4

<PAGE>

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.  Failure  to give the  notice  referred  to herein  shall not affect the
validity  or legality  of the action  which  should have been the subject of the
notice.

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  under the 1933 Act or subsequent to one year
from the date hereof 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 Units or Common Stock
which may be subscribed  for and purchased  hereunder,  each such new Warrant to
represent  the right to subscribe  for and  purchase  such Units or Common Stock
(not to exceed the maximum  aggregate  Units or shares of Common Stock 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 Units or Common  Stock  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:

                        WARRANT TO PURCHASE COMMON STOCK
                                       OF
                            U.S. WIRELESS DATA, INC.

     This certifies that, for value received, Bold Street, LLC ("Holder"),  with
an address c/o Thomson Kernaghan & Co., 365 Bay Street,  Suite 1000, 10th Floor,
Toronto, Ontario M5H 2V2, is entitled,  subject to the terms set forth below, to
purchase from U.S. WIRELESS DATA, INC. (the "Company"),  a Colorado corporation,
150,000 fully paid and non-assessable  shares (the "Shares") of the Common Stock
of the Company ("Common Stock"), as constituted on the date hereof (the "Warrant
Issue Date"),  with the Notice of Exercise  attached  hereto duly executed,  and
simultaneous  payment  therefor  in lawful  money of the United  States,  or, as
provided  in Section 3,  Common  Stock,  at the  Exercise  Price as set forth in
Section 2 below.  The number,  character  and  Exercise  Price of such shares of
Common Stock are subject to adjustment as provided below.

          1. Term of Warrant. This Warrant shall be exercisable,  in whole or in
part,  during the term  commencing  the date hereof and ending at 5:00 p.m. (New
York City time) on April 30, 2004.

          2. Exercise Price and Number of Shares.

               2.1 Exercise Price.  The exercise price at which this Warrant may
be exercised  shall be $2.28 per share of Common Stock, as adjusted from time to
time pursuant to Section 10 hereof (the "Exercise Price").

               2.2 Number of Shares.  The number of shares of Common Stock which
may be purchased  pursuant to this Warrant shall be 150,000 shares,  as adjusted
from time to time pursuant to Section 10 hereof.

         3. Exercise of Warrant.

               (a)  The  purchase   rights   represented  by  this  Warrant  are
exercisable  by the  Holder in whole or in part at any time  during  the term of
this  Warrant,  or from time to time,  by the  surrender of this Warrant and the
Exercise  Form,  annexed  hereto duly  completed  and  executed on behalf of the
Holder,  at the office of the  Company  (or such  other  office or agency of the
Company as it may designate by notice in writing to the Holder at the address of
the Holder  appearing  on the books of the  Company)  upon payment in cash or by
check  acceptable to the Company.  In lieu of the payment of the Exercise Price,
the Holder  shall have the right (but not the  obligation),  during the exercise
period,  to require the Company to convert  this  Warrant,  in whole or in part,
into the  Warrant  Shares  as  provided  for in this  Section  (the  "Conversion
Right"). Upon exercise of the Conversion Right, the Company shall deliver to the
Holder  (without  payment by the Holder of the  Exercise  Price)  that number of
shares of Common Stock equal to (i) the number of Shares  issuable upon exercise
of the portion of the Warrant being  converted,  multiplied by (ii) the quotient
obtained by dividing  (x) the value of the Warrant on a per Share  basis) at the
time the Conversion  Right is exercised  (determined by subtracting the Exercise
Price from the Current  Market  Price (as  determined  pursuant to Section  3(d)
below),  for the shares of Common Stock  issuable  upon  exercise of the Warrant
immediately  prior to the exercise of the  Conversion  Right) by (y) the Current
Market Price of one share of Common Stock  immediately  prior to the exercise of
the Conversion  Right. The Conversion  Rights provided under this Section may be
exercised  in whole or in part and at any time and from  time to time  while any
Warrants  remain  outstanding.  In order to exercise the Conversion  Right,  the
Holder shall surrender to the Company, at its offices,  this Warrant accompanied

<PAGE>

by the Cashless  Exercise Form duly filled in and signed.  The  presentation and
surrender shall be deemed a waiver of the Holder's  obligation to pay all or any
portion of the aggregate purchase price payable for the Shares being issued upon
such  exercise of this  Warrant.  This Warrant (or so much thereof as shall have
been  surrendered  for  conversion)  shall  be  deemed  to have  been  converted
immediately  prior to the  close of  business  on the day of  surrender  of this
Warrant for conversion in accordance with the foregoing provisions.  As promptly
as  practicable  on or after the  conversion  date,  the Company shall issue and
shall deliver to the Holder (i) a certificate or certificates  representing  the
largest  number of Shares  which the Holder shall be entitled as a result of the
conversion,  and (ii) if such  Warrant is being  converted  in part only,  a new
Warrant exercisable for the number of Shares equal to the unconverted portion of
the Warrant.

               (b)  This  Warrant  shall  be  deemed  to  have  been   exercised
immediately  prior to the close of  business  on the date of its  surrender  for
exercise and the person  entitled to receive the shares of Common Stock issuable
upon such exercise  shall be treated for all purposes as the holder of record of
such shares as of the close of business on such date. As promptly as practicable
on or after such date, the Company at its expense shall issue and deliver to the
person or persons entitled to receive the same a certificate or certificates for
the number of shares issuable upon such exercise. In the event that this Warrant
is exercised in part,  the Company at its expense will execute and deliver a new
Warrant  of like  tenor  exercisable  for the  number of shares  for which  this
Warrant may then be exercised.

               (c) If this  Warrant is  exercised  in part this  Warrant must be
exercised or converted,  as the case may be, for a number of whole shares of the
Common Stock.

               (d) The  Current  Market  Price  per  Share on any date  shall be
deemed  to be the  average  of the daily  closing  bid  prices  for the five (5)
consecutive trading days immediately preceding the date in question. The closing
price for each day shall be the last  reported  sales  price  regular way or, in
case no such  reported  sale  takes  place on such day,  the  closing  bid price
regular way, in either case on the  principal  national  securities  exchange on
which the Common  Stock is listed or admitted to trading or, if the Common Stock
is not listed or admitted to trading on any national  securities  exchange,  the
highest  reported  bid price for the Common  Stock as  furnished by the National
Association of Securities Dealers, Inc. through NASDAQ or a similar organization
if NASDAQ  is no  longer  reporting  such  information.  If on any such date the
Common  Stock is not listed or  admitted to trading on any  national  securities
exchange and is not quoted by NASDAQ or any similar organization, the fair value
of a share of Common  Stock on such  date,  as  determined  in good faith by the
Board of Directors  of the  Company,  whose  determination  shall be  conclusive
absent manifest error, shall be used.

          4.  Replacement  of  Warrant.   On  receipt  of  evidence   reasonably
satisfactory to the Company of the loss, theft destruction or mutilation of this
Warrant  and,  in the case of loss,  theft or  destruction,  on  delivery  of an
indemnity agreement reasonably satisfactory in form and substance to the Company
or, in the case of mutilation,  on surrender and  cancellation  of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor and amount.

          5. Rights of Stockholders. The Holder shall not be entitled to vote or
receive  dividends or be deemed the holder of Common Stock,  nor shall  anything

directors or upon any matter  submitted to stockholders at any meeting  thereof,
or to give or  withhold  consent  to any  corporate  action  (whether  upon  any

          6. Transfer of Warrant.

               6.1  Exchange of Warrant  Upon a Transfer.  Upon  delivery by the
transferee  of a written  agreement to be bound by the terms of this Warrant and
surrender of this Warrant for exchange,  properly  endorsed and  transferred  in
accordance  with this Section 6, the Company at its expense shall issue to or on
the order of the Holder a new warrant or warrants of like tenor,  in the name of
the Holder or as the Holder (on payment by the Holder of any applicable transfer
taxes) may direct, of the number of shares issuable upon exercise hereof.

               6.2 Restrictions on Transfer; Compliance with Securities Laws.

               (a)  The  Holder  of  this   Warrant,   by   acceptance   hereof,
acknowledges  that this Warrant and the shares of Common Stock to be issued upon
exercise  hereof are being acquired  solely for the Holder's own account and not
as a nominee for any other party,  and for  investment and agrees to comply with
the  transfer  restrictions  contained  in this Section 6.2. The Holder will not
offer,  sell or otherwise  dispose of this Warrant or any shares of Common Stock
to be issued upon exercise hereof  ("Shares"),  except under  circumstances that
will not result in a violation of applicable  federal and state securities laws.
Prior to offering, selling or otherwise disposing of the Warrants or Shares, the
holder hereof or thereof will give the Company a written  notice  describing the
manner and  circumstances  of the transfer  accompanied  by, if requested by the
Company,  a written opinion of legal counsel  satisfactory to the Company to the
effect,  as  amended,  that  the  proposed  transfer  may  be  effected  without
registration  under the  Securities  Act of 1933 or any state blue sky law.  Any
Warrant or Shares  transferred  in  violation  of  applicable  federal and state
securities laws shall be void and not recognized by the Company.  Any transferee
of this Warrant or Shares shall execute an agreement agreeing to be bound by the
terms of this Section 6.

               (b) All shares of Common Stock issued upon exercise  hereof shall
be stamped or imprinted  with a legend in  substantially  the following form (in
addition to any legend required by state securities laws):

     "THE SECURITIES  REPRESENTED  HEREBY HAVE NOT BEEN REGISTERED  UNDER UNITED
     STATES  FEDERAL OR STATE  SECURITIES  LAWS AND MAY NOT BE OFFERED FOR SALE,
     SOLD  OR  OTHERWISE   TRANSFERRED  OR  ASSIGNED  FOR  VALUE,   DIRECTLY  OR
     INDIRECTLY,  NOR MAY THE  SECURITIES  BE  TRANSFERRED  ON THE  BOOKS OF THE
     COMPANY,  WITHOUT  REGISTRATION  OF SUCH  SECURITIES  UNDER ALL  APPLICABLE
     UNITED STATES  FEDERAL  SECURITIES  LAWS OR  COMPLIANCE  WITH AN APPLICABLE
     EXEMPTION  THEREFROM,  SUCH COMPLIANCE AT THE OPTION OF THE COMPANY,  TO BE
     EVIDENCED BY AN OPINION OF SHAREHOLDER'S COUNSEL, IN FORM ACCEPTABLE TO THE
     COMPANY,  THAT NO VIOLATION OF SUCH  REGISTRATION  PROVISIONS  WOULD RESULT
     FROM ANY PROPOSED TRANSFER OR ASSIGNMENT."

          7.  Reservation of Stock.  The Company  covenants that during the term
that this Warrant is  exercisable,  the Company will reserve from its authorized
and  unissued  Common  Stock a  sufficient  number of shares to provide  for the
issuance of Common Stock upon the  exercise of this  Warrant  and,  from time to
time, will take all steps  necessary to amend its  Certificate of  Incorporation
(the  "Certificate")  to provide  sufficient  reserves of shares of Common Stock
issuable upon the exercise of the Warrant.  The Company  further  covenants that
all shares that may be issued upon the  exercise of rights  represented  by this
Warrant,  upon exercise of the rights represented by this Warrant and payment of
the Exercise Price, all as set forth herein,  will be free from all taxes, liens
and charges in respect of the issue thereof  (other than taxes in respect of any
transfer occurring contemporaneously or otherwise specified herein), and will be
validly issued, fully paid and nonassessable.

                                       3

          8.  Notices.   Whenever  the  Exercise   Price  or  number  of  shares
purchasable  hereunder  shall be  adjusted  pursuant  to Section 10 hereof,  the
Company shall issue a certificate  signed by its Chief Financial Officer setting
forth, in reasonable detail,  the event requiring the adjustment,  the amount of
the  adjustment,  the method by which such  adjustment was  calculated,  and the
Exercise Price and number of shares purchasable hereunder after giving effect to
such  adjustment,  and shall cause a copy of such  certificate  to be mailed (by
first-class mail, postage prepaid) to the Holder of this Warrant.

          9. Amendments.

               (a) Any term of this  Warrant  may be  amended  with the  written
consent of the Company and the Holder. Any amendment effected in accordance with
this  Section 9 shall be binding  upon the Holder,  each  future  Holder and the
Company.

               (b) No  waivers  of, or  exceptions  to, any term,  condition  or
provision of this Warrant, in any one or more instances,  shall be deemed to be,
or construed as, a further or continuing  waiver of any such term,  condition or
provision.

          10. Adjustments. The number of shares purchasable hereunder is subject
to adjustment from time to time as follows:

               10.1  Reorganization,  Merger or Sale of  Assets.  If at any time
while this Warrant,  or any portion thereof,  is outstanding and unexpired there
shall  be (i) a  reorganization  (other  than a  combination,  reclassification,
exchange or subdivision of shares otherwise provided for herein),  (ii) a merger
or  consolidation  of the Company with or into another  corporation in which the
Company is not the surviving entity, or a reverse triangular merger in which the
Company is the surviving  entity but the shares of the  Company's  capital stock
outstanding  immediately  prior to the  merger  are  converted  by virtue of the
merger  into  other  property,  whether  in the  form  of  securities,  cash  or
otherwise,  or (iii) a sale or transfer of the Company's  properties  and assets
as, or  substantially  as, an entirety to any other  person,  then, as a part of
such reorganization,  merger, consolidation,  sale or transfer, lawful provision
shall be made so that the holder of this Warrant shall thereafter be entitled to
receive upon payment of the Exercise Price then in effect,  the number of shares
of stock or other securities or property of the successor  corporation resulting
from such reorganization,  merger, consolidation, sale or transfer that a holder
of the shares deliverable upon exercise of this Warrant would have been entitled
to receive in such  reorganization,  consolidation,  merger, sale or transfer if
this Warrant had been exercised immediately before such reorganization,  merger,
consolidation,  sale or transfer,  all subject to further adjustment as provided
in this  Section  10.  The  foregoing  provisions  of this  Section  10.1  shall
similarly apply to successive  reorganizations,  consolidations,  mergers, sales
and transfers and to the stock or securities of any other  corporation  that are
at the time  receivable  upon the  exercise of this  Warrant.  If the  per-share
consideration  payable to the Holder  hereof for shares in  connection  with any
such transaction is in a form other than cash or marketable securities, then the
value of such  consideration  shall be determined in good faith by the Company's
Board of Directors. In all events, appropriate adjustment (as determined in good
faith by the Company's  Board of Directors)  shall be made in the application of
the  provisions  of this Warrant with respect to the rights and interests of the
Holder after the  transaction,  to the end that the  provisions  of this Warrant
shall be applicable  after that event, as near as reasonably may be, in relation
to any shares or other  property  deliverable  after that event upon exercise of
this Warrant.

               10.2  Reclassification.  If the  Company,  at any time while this
Warrant,  or  any  portion  thereof,   remains  outstanding  and  unexpired,  by
reclassification of securities or otherwise,  shall change any of the securities
as to  which  purchase  rights  under  this  Warrant  exist  into  the same or a
different number of securities of any other class or classes, this Warrant shall
thereafter  represent the right to acquire such number and kind of securities as
would  have been  issuable  as the  result of such  change  with  respect to the
securities  that  were  subject  to  the  purchase  rights  under  this  Warrant
immediately  prior to such  reclassification  or other  change and the  Exercise
Price  therefor  shall  be  appropriately   adjusted,  all  subject  to  further
adjustment as provided in this Section 10.

               10.3 Dividend,  Split,  Subdivision or Combination of Shares.  If
the  Company at any time while this  Warrant,  or any portion  thereof,  remains
outstanding and unexpired shall (i) declare a dividend or make a distribution on
the securities as to which  purchase  rights under this Warrant exist payable in
shares of its capital stock or securities  convertible  into or exchangeable for
capital  stock or (ii) split,  subdivide or combine the  securities  as to which
purchase rights under this Warrant exist, then, in each case, the Exercise Price
in effect,  and the number of shares  issuable upon exercise of the Warrant,  at
the time of the record date for such dividend or at the  effective  date of such
split, subdivision or combination, shall be proportionately adjusted so that the
holders  of the  Warrant  after  such time shall be  entitled  to  receive  upon
exercise of the Warrant the aggregate  number and kind of shares which,  if such
Warrant had been exercised  immediately  prior to such time,  such holders would
have owned upon such  exercise  and  immediately  thereafter  been  entitled  to
receive by virtue of such  dividend,  split,  subdivision or  combination.  Such
adjustment  shall be made  successively  whenever  any event  listed above shall
occur, subject to further adjustment as provided in this Section 10.

          11.  Registration  Rights.  Holder  shall have  unlimited  "piggyback"
registration rights as to the Shares, provided that Holder shall not be entitled
to  "piggyback"  on a  registration  statement  with respect to an  underwritten
public offering if (a) the underwriter advises the Company that the inclusion of
the Shares would adversely  affect the  contemplated  public offering and (b) no
affiliates of the Company are selling stockholders in such offering. The Company
shall bear the expenses related to any such registration, except for commissions
or discounts payable to broker-dealers in respect of the sale of the Shares. The
registration  rights  referred  to herein  shall  terminate  if the  Shares  are
saleable without  restriction under Rule 144(k) promulgated under the Securities
Act of 1933.

     IN WITNESS  WHEREOF,  the Company has caused this Warrant to be executed by
its officers thereunto duly authorized.
