INITIAL CLOSING OF PRIVATE OFFERING OF SERIES B CUMULATIVE
CONVERTIBLE REDEEMABLE PREFERRED STOCK AND COMMON STOCK PURCHASE WARRANTS

         On May 6, 1999 (the "Closing  Date"),  U.S.  Wireless  Data,  Inc. (the
"Company")  closed  the  minimum  amount of a  private  offering  of  $1,500,000
minimum,  $5,000,000  maximum,  of Series B  Cumulative  Convertible  Redeemable
Preferred Stock (the "Series B Preferred"),  selling  1,500,000  shares at $1.00
per share,  with a stated  value of $1.00 per share.  In addition to the sale of
1,500,000  shares of Series B Preferred  for cash, a total of 454,705  shares of
Series B Preferred  was issued to the holders of the  Company's  6%  Convertible
Subordinated  Debentures  Due  July  21,  2000  (the  "6%  Debentures"),  to pay
penalties and interest owing under the 6% Debentures  through June 30, 1999. The
holders of the 6% Debentures  also agreed to waive certain prior defaults on the
6% Debentures and the related  registration rights agreement in exchange for the
issuance of the Series B Preferred to them, together with certain  modifications
to the 6% Debentures and the Company's registration  obligations relating to the
underlying Common Stock issuable upon conversion of the 6% Debentures.

         The Company also issued a Common Stock Purchase Warrant  exercisable to
purchase  300,000  shares of Common Stock at $1.50 per share for five years from
April 30, 1999 (the "Series B Warrants")  to the cash  purchaser of the Series B
Preferred. Holders of the 6% Debentures did not receive Series B Warrants

         Net proceeds to the Company  from  closing the minimum  offering of the
Series B Preferred will be approximately $1,279,000, after paying a finder's fee
of $180,000 plus estimated offering expenses of $41,000 (including approximately
$25,800 for the investor's legal fees). The Company immediately used $400,800 of
the  proceeds to repay  $400,000 of short term loans from the  purchaser  of the
Series B  Preferred,  which it made to the Company  over the  three-week  period
prior to closing of the minimum offering. The Company is obligated to utilize an
additional  $413,000 of the proceeds to pay past and future legal and accounting
fees, while the estimated balance of $465,200 is to be used as working capital.

         RBB Bank  Aktiengesselschaft,  which is the  agent for the  holders  of
certain  shares of the  Company's  Series A Preferred  Stock,  $1,000,000  of 6%
Debentures and a promissory note in the principal amount of $250,000,  agreed to
waive  the  right  to  immediate  repayment  of the  $250,000  note  (which  was
originally  payable upon completion of the next funding  received by the Company
of at least  $1,000,000).  RBB Bank  agreed  to  forebear  initiating  an action
against the Company to collect the  obligation  evidenced  by the Note until the
first to occur of: (a) receipt by the Company of funding in the  aggregate of at
least $2,500,000; or (b) December 1, 1999.

         Mr. John  Liviakis,  a  significant  shareholder  of the Company,  also
agreed to transfer a total of 443,077  shares of Company  Common  Stock owned by
him to the finder  who  located  the cash  purchaser  of the Series B  Preferred
Stock.  The shares will be transferred as "restricted  securities" as defined in
Rule 144 under  the  Securities  Act of 1933 and will not have any  registration
rights.

         The  offering  is being made  pursuant to the  registration  exemptions
contained  in  Section  4(2) of the  Securities  Act of 1933,  as  amended  (the
"Securities Act") and Rule 506 of Regulation D promulgated  thereunder.  Neither
the  Series  B  Preferred  nor the  Warrants  nor the  shares  of  Common  Stock
underlying  those  securities have been registered  under the Securities Act and
may not be  offered  or sold in the  United  States  absent  registration  or an
applicable exemption from registration requirements.

OTHER KEY TERMS OF THE OFFERING,  THE  SECURITIES  AND  APPLICABLE  REGISTRATION
RIGHTS

         The  following is a summary of additional  key terms and  conditions of
certain  agreements  entered into between the Company and the  purchasers of the
Series B Preferred  (including  the holders of the 6%  Debentures).  The summary
descriptions  contained  herein are qualified in their  entirety by reference to
copies of the  operative  documents,  including the Articles of Amendment to the
Company's  Articles of  Incorporation  (containing  the  Designation of Series B
Cumulative    Convertible    Redeemable    Preferred   Stock)   (hereafter   the
"Designation"),  the Securities Purchase Agreement, the Supplement to Securities
Purchase Agreement entered into with the holders of the Company's 6% Debentures,
the Registration  Rights Agreement,  the Waiver of Rights and First Amendment to
Debenture  Agreement and the First  Amendment to Note and Common Stock  Purchase
Agreement  entered  into April 22,  1999,  which are filed as  Exhibits  to this
Report.

Dividends
- ---------

         The Series B Preferred accrues a cumulative dividend at the annual rate
of 6% per annum,  payable  semi-annually  on March 31 and  September  30 of each
year.  The  dividend  may be paid at the  Company's  option in cash or shares of
Common  Stock.  If paid in Common  Stock,  the  number of shares  issuable  as a
dividend is determined  based on the amount of the dividend being paid,  divided
by the  "Average  Quoted  Price" of the  Common  Stock,  which is defined in the
Designation to be the five-day  average closing bid price of the Common Stock as
quoted on the OTC Electronic  Bulletin Board or one of the NASDAQ markets (if so
listed and quoted) or any other  exchange  where the Common  Stock is listed and
quoted.  All  dividends  owing to the date of  conversion  are payable  upon any
conversion.

Voting Rights
- -------------

         Generally, the Series B Preferred does not have voting rights, although
it is entitled to one vote per share on those  matters upon which all classes of
a Colorado  corporation's  shares are entitled by law to vote upon by class.  In
that case,  a majority of the Series B Preferred  Stock,  voting as a class,  is
required to approve any such  matter.  On any matter that the Series B Preferred
would be entitled to vote upon in the same class as Common Stock,  each share of
the Series B  Preferred  is entitled to that number of votes equal to the number
of shares of Common  Stock into which it would be  convertible  as of the record
date for the matter being voted upon.

Conversion Terms
- ----------------

         50% of the Series B Preferred Stock is convertible at the option of the
holders into shares of the Company's Common Stock beginning on the earlier of 90
days after its  issuance  date or five days after notice by the  Securities  and
Exchange Commission that the registration statement (to be filed pursuant to the
terms  of  the  Registration  Rights  Agreement)  (the  "Series  B  Registration
Statement") may be declared  effective.  Thirty days  thereafter,  the remaining
shares of the Series B Preferred becomes convertible into Common Stock. The rate
at which the Series B Preferred is convertible  (per share of Series B Preferred
Stock) into Common Stock is equal to 80% of the average of the closing bid price
of the  Common  Stock  over the five  trading  days  prior  to  conversion  (the
"Conversion  Rate").  The Company may convert the Series B Preferred into Common
Stock at its  option at any time after the close of the  business  on the second
anniversary of the effectiveness date of the Series B Registration  Statement at
the then-applicable Conversion Rate.

         Subject to certain  exceptions  applicable to mandatory  conversions at
the behest of the Company  and  automatic  conversions  upon the  occurrence  of
certain  "Fundamental  Changes" (as defined in the  Designation),  to the extent
that  convertibility of Series B Preferred would result in beneficial  ownership
(as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934,
as amended) by a holder in excess of 4.99% of the Company's  Common  Stock,  the
number of shares of Series B Preferred  that  result in such  excess  beneficial
ownership is not then  convertible,  notwithstanding  any other provision making
them eligible for conversion.

Registration Rights
- -------------------

         The Company also entered into an agreement  (the  "Registration  Rights
Agreement") with the purchasers of the Series B Preferred to file a registration
statement  with the SEC  covering  the  Common  Stock  underlying  the  Series B
Preferred  and the  Warrants  within 30 days of the Closing  Date (the "Series B
Registration Statement"), to be effective within 90 days of the Closing Date. If
the Company fails to file the Series B Registration  Statement within 30 days of
the Closing Date (the "Required Filing Date"), a late filing penalty becomes due
and payable one day  thereafter in the amount of 3% of the purchase price of the
Series B Preferred  Stock,  with an  additional  3% penalty due on each  monthly
anniversary  following  the  Required  Filing  Date  during  which the  Series B
Registration  Statement  has  not  been  filed.  If the  Series  B  Registration
Statement  is not  effective  with the SEC on or before the earlier of five days
after  notice from the SEC that it may be declared  effective  or 90 days of the
Closing  Date (the  "Required  Effective  Date"),  a penalty  equal to 3% of the
purchase price of the Series B Preferred will be due and owing by the Company to
the holders,  with an additional  penalty equal to 2% of the purchase  price due
and owing on each  monthly  anniversary  thereafter  during  which the  Series B
Registration  Statement is not declared effective.  In addition, if the Series B
Registration  Statement has not been filed within 60 days of the Closing Date or
has not been declared effective within 150 days of the Closing Date, the holders
of the  Series B  Preferred  may  require  the  Company  to redeem  the Series B
Preferred for $1.25 per share, plus all accrued dividends.

         The filing by the Company of the Series B  Registration  Statement will
activate certain prior registration  rights granted by the Company to holders of
certain of its securities.  The Company estimates that in addition to the shares
it will be required to register to cover  conversions of the Series B Preferred,
it will include up to an  approximately  7,000,000  additional  shares of Common
Stock on the Series B Registration  Statement to honor such registration  rights
(including 150% of the shares needed to cover conversions of the 6% Debentures).
This  estimated  share  number is based upon a last sale price of the  Company's
Common Stock of $.875 as of May 10, 1999.

Amendment of 6% Debentures
- --------------------------

         Contemporaneously  with the  initial  closing of the Series B Preferred
placement the holders of all $2,000,000  face value of the 6% Debentures  agreed
to accept  payment of all interest owing through June 30, 1999  (including  past
due interest)  and  penalties  owing by the Company for failure to timely file a
registration  statement to register the shares of Common Stock underlying the 6%
Debentures.  In total the Company  issued a total of 454,705  shares of Series B
Preferred to the holders of the 6% Debentures to cover  $454,705 of interest and
penalties.  The 6% Debenture  holders also agreed to waive all past  defaults on
the 6% Debentures  arising out of the failure to pay interest or timely register
the underlying shares of Common Stock. The holders further agreed not to declare
the 6%  Debentures  in default  for  failure to pay  interest  or  register  the
underlying  shares of Common  Stock unless and until the holders of the Series B
Preferred have the right to require the Company to redeem the Series B Preferred
in the  event  the  Company  fails  to  either  file the  Series B  Registration
Statement  within 60 days of the Closing  Date or achieve  effectiveness  of the
Series B Registration Statement within 150 days of the Closing Date. The Company
also agreed to include the shares  underlying  the 6% Debentures in the Series B
Registration Statement and that the same cash penalty provisions as apply to the
Series B  Preferred  will apply to the 6%  Debentures  in the event the  Company
fails to file the Series B Registration  Statement within 30 days of the Closing
Date and to achieve effectiveness of it within 90 days of the Closing Date.

                       DESIGNATION OF SERIES B CUMULATIVE
                     CONVERTIBLE REDEEMABLE PREFERRED STOCK


                  U.S.   Wireless  Data,  Inc.,  a  Colorado   corporation  (the
"Corporation"),  hereby  designates the  preferences,  limitations  and relative
rights of its Series B  Cumulative  Convertible  Redeemable  Preferred  Stock as
follows:

A.       Description and Designation of Series B Preferred
         -------------------------------------------------

         1.       Designation and Definitions.
                  ----------------------------

                  (a)  Designation.  Five  Million  (5,000,000)  shares  of  the
Corporation's 15,000,000 total authorized shares of no par value preferred stock
are hereby designated as Series B Cumulative  Convertible  Redeemable  Preferred
Stock  (hereinafter  referred  to as the  "Series B  Preferred").  The  Series B
Preferred shall have a stated value (original issue price) of one dollar ($1.00)
per share (the "Original Issue Price").

                  (b) Certain Definitions.  As used herein, the following terms,
unless the context otherwise requires, have the following respective meanings:

                           (i)      "Average  Quoted  Price"  means the  average
of the closing bid price of the Common Stock of the  Corporation  as reported by
the Nasdaq Bulletin Board,  Nasdaq SmallCap Market or Nasdaq National Market or,
if the Corporation's  Common Stock is no longer traded on a Nasdaq market,  such
other exchange on which the Corporation's  Common Stock is then traded,  for the
five (5) trading days  immediately  preceding any holder's  Conversion Date, the
Mandatory  Conversion Date (as defined in Section 5(c) below) or the date of the
consummation or closing of a Fundamental Change, as the case may be.

                           (ii)  "Conversion  Date" means each date on which the
Corporation receives by
telecopy  written notice in accordance with Section 5(j) hereof from a holder of
Series B  Preferred  that such holder  elects to convert  shares of its Series B
Preferred.

                           (iii)  "Fundamental  Change"  means:  (i)  any  sale,
lease,  exchange or other transfer of all or substantially  all of the assets of
the Corporation; or (ii) any merger or consolidation to which the Corporation is
a party. Notwithstanding the foregoing, the following shall not be a Fundamental
Change: A merger or  consolidation  (a) to which the Corporation is a party; (b)
in  which  it  is  the   surviving   corporation   and  there  is  no  resulting
reclassification of the outstanding Common Stock; and (c) after giving effect to
which, 

                                      A-1
<PAGE>
persons who were,  immediately before the consummation or closing of such merger
or  consolidation,  holders of  outstanding  Common  Stock will be the direct or
indirect owners of securities of the Corporation possessing,  on a fully diluted
basis,  at least  seventy-five  percent  (75%) of the voting power of all voting
securities of the Corporation (excluding, for purposes of such computation,  any
such person who also is a party to such merger or consolidation).

                           (iv) "Issue Date"  means,  with respect to each share
of Series B  Preferred  held by any  holder,  the date on which the  Corporation
originally  issued such share to such  holder  (irrespective  of any  subsequent
transfer or other disposition of such share to any other holder).

         2.       Dividends.
                  ----------

                  (a)  Preferred  Dividend - Cash  and/or  In-Kind.  When and as
declared by the Board of Directors  and to the extent  permitted by the Colorado
Business  Corporation Act, the Corporation  shall pay preferential  dividends to
the holders of the Series B Preferred as provided in this Section 2(a).

                           (i)       Preferred   Dividend.  Except as  otherwise
provided  herein,  dividends on each share of Series B Preferred  shall  accrue,
cumulatively  on a daily basis, at the rate of six percent (6%) per annum of the
Original  Issue Price,  from and  including  the Issue Date of such share to and
including the date on which the Liquidation  Value of such share is paid or such
share is converted in  accordance  with the  provisions  hereof (the  "Preferred
Dividend").  Such  Preferred  Dividend  will  accrue  whether or not it has been
declared  and  whether or not there are  profits,  surplus or other funds of the
Corporation legally available for its payment.

                           (ii)     Semi-Annual Payments.         Commencing  on
September 30, 1999, the Preferred  Dividend shall be payable in cash (subject to
Section 2(a)(v) below) semi-annually,  for the actual number of days elapsed, on
each March 31 and  September  30, to the holders of record of shares of Series B
Preferred as of the tenth (10th) trading day preceding the  applicable  dividend
payment date.

                           (iii)  No  Interest.  Accrued  but  unpaid  Preferred
Dividends shall not bear interest.
Preferred Dividends paid in cash in an amount less than the total amount of such
dividends at the time accrued and payable shall be allocated on a share-by-share
basis among all shares of Series B Preferred at the time outstanding.

                           (iv)     Payment  Upon  Conversion.  On  the  date on
which any holder's  shares of Series B Preferred are converted into Common Stock
pursuant to Section 5 hereof, the accrued Preferred Dividend with respect to the
shares  so  converted  shall  be paid  to such  holder.  All  accrued  Preferred
Dividends also shall be payable upon the liquidation,  

                                      A-2
<PAGE>
dissolution or winding up of the Corporation.

                           (v)      Payment in  Common  Stock.  The Corporation,
at its sole discretion,  may pay the Preferred Dividends in cash or in shares of
Common  Stock at the then fair market  value per share of Common Stock as of the
date on which the  Preferred  Dividend is payable.  For purposes of this Section
2(a)(v),  fair market value shall be the average of the closing bid price of the
Common Stock of the  Corporation  as reported by the Nasdaq  SmallCap  Market or
Nasdaq National Market or, if the Corporation's Common Stock is no longer traded
on a Nasdaq market, such other exchange on which the Corporation's  Common Stock
is then traded, for the five (5) trading days immediately  preceding the date on
which the Preferred Dividend is payable.

                           (vi)     Fractional  Shares.          Notwithstanding
anything herein to the contrary,  no fractional  shares shall be issued pursuant
to this  Section 2, and the  number of shares of Common  Stock  issued  upon the
payment of the  Preferred  Dividend  shall be rounded up or down to the  nearest
whole share, with fractional shares of 0.5 or greater being rounded up.

                  (b)  Declared  Dividends  on  Common  Stock.  If the  Board of
Directors shall declare a cash dividend payable upon the then outstanding shares
of Common  Stock (other than a stock  dividend on the Common  Stock  distributed
solely in the form of  additional  shares of Common  Stock),  the holders of the
Series B Preferred  Stock shall be  entitled to the amount of  dividends  on the
Series B Preferred as would be declared  payable on the largest  number of whole
shares of Common Stock into which the shares of Series B Preferred  held by each
holder  thereof  could be  converted  pursuant  to the  provisions  of Section 5
hereof,  such number  determined as of the record date for the  determination of
holders of Common Stock entitled to receive such dividend. Such determination of
"whole  shares" shall be based upon the  aggregate  number of shares of Series B
Preferred held by each holder,  and not upon each share of Series B Preferred so
held by the holder.

                  (c)  Dividends on Other  Securities.  Subject to the foregoing
provisions  of this  Section  2, the  Board of  Directors  may  declare  and the
Corporation may pay or set apart for payment, or cause the accrual of, stated or
cumulative  dividends and other distributions on the Series A Preferred Stock of
the  Corporation,  or any other series of preferred stock hereafter  designated,
and may purchase or otherwise  redeem any of the same (or any warrants,  rights,
options or other securities  exercisable therefor or convertible or exchangeable
there  into),  and the  holders of Series B  Preferred  shall not be entitled to
share therein.

         3.       Liquidation, Dissolution or Winding Up.
                  ---------------------------------------

                  (a) Treatment at  Liquidation,  Dissolution  or Winding Up. In
the event of any  liquidation,  dissolution  or winding  up of the  Corporation,
whether voluntary or involuntary, or in the event of its insolvency,  before any
distribution  or  payment is made to 

                                      A-3
<PAGE>
any holders of Common Stock or any other class or series of capital stock of the
Corporation  designated  to be junior to the Series B Preferred,  and subject to
the liquidation rights and preferences of any class or series of Preferred Stock
designated  by the  Board of  Directors  in the  future  to be senior to or on a
parity with the Series B Preferred with respect to liquidation preferences,  the
holder of each share of Series B  Preferred  shall be  entitled to be paid first
out of the assets of the  Corporation  available for  distribution to holders of
the Corporation's capital stock of all classes, whether such assets are capital,
surplus or earnings,  an amount  equal to the Original  Issue Price per share of
Series B Preferred held by any holder,  plus the Preferred  Dividend accruing to
such share of Series B Preferred  pursuant to Section 2 above (the  "Liquidation
Value").  For purposes hereof,  the Series B Preferred shall rank on liquidation
junior to the Series A Preferred Stock.

                  If,  upon  liquidation,  dissolution  or  winding  up  of  the
Corporation,  the assets of the  Corporation  available for  distribution to its
stockholders  shall be insufficient to pay the holders of the Series B Preferred
the full amount to which they otherwise would be entitled, the holders of Series
B Preferred shall share ratably in any distribution of available assets pro rata
in  proportion  to the  respective  liquidation  preference  amounts which would
otherwise be payable upon liquidation with respect to the outstanding  shares of
the Series B Preferred  if all  liquidation  preference  amounts with respect to
such  shares  were paid in full,  based  upon the  aggregate  Liquidation  Value
payable upon all shares of Series B Preferred then outstanding.

                  After such payment shall have been made in full to the holders
of the Series B Preferred,  or funds  necessary for such payment shall have been
set aside by the Corporation in trust for the account of holders of the Series B
Preferred so as to be available for such payment, the remaining assets available
for  distribution  shall be distributed  ratably among the holders of the Common
Stock and any class or series of capital  stock  designated  to be junior to the
Series  B  Preferred  (if  any)  in  right  of  payment  upon  any  liquidation,
dissolution or winding up of the Corporation.

                  The  amounts  set forth  above  shall be subject to  equitable
adjustment  by the  Board  of  Directors  whenever  there  shall  occur  a stock
dividend,   stock   split,   combination,   reorganization,    recapitalization,
reclassification  or other  similar  event  involving  a change  in the  capital
structure of the Series B Preferred.

                  (b) Distributions  Other than Cash. Whenever the distributions
provided for in this Section shall be payable in property  other than cash,  the
value of such  distribution  shall be the fair market value of such  property as
determined in good faith by the Board of Directors. All distributions (including
distributions  other  than cash)  made  hereunder  shall be made pro rata to the
holders of Series B Preferred.

                  (c)  Events Not Deemed a  Liquidation.  Neither  the merger or
consolidation of the Corporation into or with any other corporation(s),  nor the
sale or transfer by the  Corporation  of all or any part of its assets,  nor the
reduction  of the  capital  stock of the  

                                      A-4
<PAGE>
Corporation,  will be deemed to be a  liquidation,  dissolution or winding up of
the Corporation under this Section 3.

         4.       Voting Power.
                  -------------

                  (a) General.  The holders of Series B Preferred  will not have
any voting  rights  except as set forth below or as otherwise  from time to time
required by law.
                  To the extent that under  Colorado law the vote of the holders
of Series B Preferred,  voting separately as a class, is required to authorize a
given action of the Corporation,  the affirmative vote or consent of the holders
of at least a majority of the  outstanding  shares of Series B  Preferred  shall
constitute  the  approval of such action by the class.  To the extent that under
Colorado law the holders of Series B Preferred  are entitled to vote on a matter
with holders of Common Stock, voting together as one class, each share of Series
B Preferred shall be entitled to a number of votes equal to the number of shares
of Common Stock into which it is then convertible  using the record date for the
taking of such vote of stockholders as the date as of which the Conversion Price
is calculated.  Holders of Series B Preferred shall be entitled to notice of all
shareholders  meetings or written  consents  regardless of whether they would be
entitled to vote with respect thereto,  which notice would be provided  pursuant
to the Corporation's by-laws and applicable statutes.

                  (b) Amendments to Charter. For so long as there are any shares
of Series B Preferred outstanding,  the Corporation shall not amend its Articles
of  Incorporation or this  Certificate of Designation  without the approval,  by
vote or written  consent,  of the  holders  of at least a  majority  of the then
outstanding shares of Series B Preferred, voting together as a class, each share
of Series B  Preferred  to be  entitled  to one vote in each  instance,  if such
amendment  would  adversely  affect  the  rights  of the  holders  of  Series  B
Preferred;  provided, that the creation, or increase in the authorized number of
shares, of any class or series of stock ranking prior to or on a parity with the
Series B  Preferred  either as to  dividends  or upon  liquidation  shall not be
deemed to adversely  affect the rights of the holders of Series B Preferred  for
purposes of this Section 4(b).

         5.       Conversion Rights.
                  ------------------

                  (a) Conversion at the Option of Holders. Beginning the earlier
of ninety (90) days after the Issue Date to such holder,  or five (5) days after
notice by the Securities and Exchange Commission that the Registration Statement
(filed with the SEC pursuant to the  Registration  Rights  Agreement,  dated the
date hereof,  between the Company and the holders of the Series B Preferred) may
be declared  effective,  each such  holder of Series B Preferred  shall have the
right,  at such  holder's  option,  to convert up to fifty  percent (50%) of the
shares of Series B Preferred  held by such holder into such number of fully paid
and  nonassessable  shares of Common Stock as shall be determined by multiplying
the number of shares of Series B Preferred to be  converted  by a fraction,  the
numerator of which is the Original Issue Price,  and the denominator of which is
the applicable  Conversion Price (as defined below).  Beginning thirty (30) days
thereafter,  all of the Preferred Stock shall,  at 

                                      A-5
<PAGE>
the option of the Holder, be convertible.

                  (b)  Conversion  Price.  The  conversion  price per share (the
"Conversion Price") shall be equal to Eighty Percent (80%) of the Average Quoted
Price.

                  (c) Conversion at Option of Corporation. At any time after the
close of business on the second (2nd) year  anniversary of the date on which the
Securities and Exchange Commission declares effective the registration statement
registering  the shares of Common Stock issuable upon conversion of the Series B
Preferred, all of the shares of Series B Preferred shall be convertible,  at the
option of the  Corporation,  into such  number of fully  paid and  nonassessable
shares of Common  Stock as shall be  determined  by  multiplying  the  number of
shares of Series B Preferred  outstanding on the Mandatory  Conversion  Date (as
defined  below) by a fraction,  the  numerator  of which is the  Original  Issue
Price, and the denominator of which is the applicable Conversion Price.

         The  Corporation  shall give notice of its exercise of such  conversion
option to all holders of Series B Preferred  no later than five (5) trading days
before the date as of which the  Corporation has elected to make such conversion
effective  (such  effective date of the  conversion,  the "Mandatory  Conversion
Date").  Each holder of Series B Preferred as of the Mandatory  Conversion  Date
shall,  promptly after such date, surrender for conversion to the Corporation at
its principal  office or to any transfer agent for the Series B Preferred or the
Common Stock all certificates representing all shares of Series B Preferred held
by such holder,  accompanied by a written notice specifying the name or names in
which such holder  wishes the  certificate(s)  for shares of Common  Stock to be
issued.

         Effective as of the close of business on the Mandatory Conversion Date,
each share of Series B  Preferred  then  outstanding  shall be (and be deemed to
have been)  converted  automatically,  without any further action by the holders
thereof,  into shares of Common Stock.  Such conversion  shall be deemed to have
occurred  whether  or  not  the  certificates   representing   such  shares  are
surrendered to the Corporation or its transfer agent.

                  (d)   Limitation   on   Number   of   Shares.    Additionally,
notwithstanding anything set forth in this Section 5 to the contrary:

                           (i)      in  no event  shall  any  holder of Series B
Preferred, prior to the earlier to occur of the Mandatory Conversion Date or the
date of the  consummation  or closing of a  Fundamental  Change,  be entitled to
convert  Series B Preferred  into shares of Common  Stock to the extent that (x)
the number of shares of the  Corporation's  Common Stock  beneficially  owned by
such holder and its  affiliates  (other than shares of Common Stock which may be
deemed  beneficially  owned through the ownership of the unconverted  portion of
the shares of Series B  Preferred  held by such  holder)  plus (y) the number of
shares of Common Stock issuable upon such conversion  would result in beneficial
ownership by the holder and its  affiliates  of more than 4.99% of the shares of
Common Stock then  outstanding.  For purposes of this Section  5(d),  beneficial
ownership shall be determined in 

                                      A-6
<PAGE>
accordance  with  Section  13(d) of the  Securities  Exchange  Act of  1934,  as
amended, and Regulation 13D and 13G promulgated thereunder,  except as otherwise
provided in clause (x) of this Section 5(d). Each holder shall,  upon delivering
to the  Corporation a notice of election to convert shares of Series B Preferred
in accordance  with Section 5(j) hereof,  be required to provide the Corporation
with a  certification  in form  and  substance  reasonably  satisfactory  to the
Corporation,  that the conversion of the Series B Preferred being converted will
not result in such  holder and its  affiliates  beneficially  holding  more than
4.99%,  determined as heretofore  provided,  of the outstanding shares of Common
Stock on such Conversion Date. If the holder cannot make such certification, the
shares  of  Series  B  Preferred  to be  converted  shall  not  be  convertible.
Notwithstanding  the foregoing,  upon the Mandatory  Conversion Date or upon the
consummation  or closing of a  Fundamental  Change,  all such shares of Series B
Preferred  then  outstanding  shall be converted into Common Stock in accordance
with Section 5(c) or 5(h), as applicable.

                           (ii) the  maximum  number  of  shares  which  will be
issued on conversion of the Series B Preferred and exercise of the Warrants,  if
any, is 3,472,583 (20% of the  outstanding  shares) (the "Share Cap") unless and
until the  shareholders of the  Corporation  shall have approved the issuance of
shares of Common Stock beyond the Cap, if such  approval is required by the NASD
or  NASDAQ,  subject  to the  redemption  rights of the  holders of the Series B
Preferred  set forth in  Sections  4(i)(x)  and (y) of the  Securities  Purchase
Agreement.

                  (e)      Intentionally Deleted.

                  (f) Dividends Other Than Common Stock Dividends.  In the event
the  Corporation  shall  make or  issue,  or  shall  fix a  record  date for the
determination of holders of Common Stock entitled to receive a dividend or other
distribution  (other than a distribution  in  liquidation or other  distribution
otherwise  provided for herein) with respect to the Common Stock  payable in (i)
securities of the  Corporation  other than shares of Common Stock, or (ii) other
assets (excluding cash dividends or distributions),  then and in each such event
provision  shall be made so that the  holders  of the Series B  Preferred  shall
receive  upon  conversion  thereof in addition to the number of shares of Common
Stock receivable thereupon, the number of securities or such other assets of the
Corporation  which they would have  received had their  Series B Preferred  been
converted  into Common Stock on the date of such event and had they  thereafter,
during the period from the date of such event to and  including  the  Conversion
Date,  retained such  securities or such other assets  receivable by them during
such period,  giving application to all other adjustments called for during such
period  under this  Section 5 with  respect to the rights of the  holders of the
Series B Preferred.

                  (g) Capital Reorganization or Reclassification.  If the Common
Stock  issuable upon the  conversion of the Series B Preferred  shall be changed
into the same or  different  number of shares of any class or classes of capital
stock, whether by capital reorganization, recapitalization,  reclassification or
otherwise  (other than a subdivision  or 

                                      A-7
<PAGE>
combination of shares or stock  dividend  provided for elsewhere in this Section
5, or the sale of all or substantially all of the Corporation's capital stock or
assets to any other person), then and in each such event the holders of Series B
Preferred  shall have the right  thereafter to convert such shares into the kind
and  amount of shares  of  capital  stock  and  other  securities  and  property
receivable upon such reorganization, recapitalization, reclassification or other
change by the  holders of the  number of shares of Common  Stock into which such
shares of Series B Preferred might have been converted immediately prior to such
reorganization,  recapitalization,  reclassification  or change,  all subject to
further adjustment as provided herein.

                  (h)  Mandatory   Conversion  -  Fundamental   Change.  If  any
Fundamental   Change  shall  occur,  then  each  share  of  Series  B  Preferred
outstanding as of the date of the  consummation or closing thereof shall be (and
be deemed to have been) converted  automatically,  without any further action by
the holders thereof,  into such number of fully paid and nonassessable shares of
Common  Stock as shall be  determined  by  multiplying  the  number of shares of
Series B Preferred  outstanding on the date of such consummation or closing date
by a fraction,  the  numerator  of which is the Original  Issue  Price,  and the
denominator of which is the applicable  Conversion  Price. Such conversion shall
be deemed to have occurred  whether or not the  certificates  representing  such
shares are surrendered to the Corporation or its transfer agent.

         The  Corporation  shall  give  notice  of  a  proposed  or  anticipated
Fundamental  Change to all holders of the Series B Preferred  not later than ten
(10)  trading  days  before  the  expected   closing  or  consummation  of  such
Fundamental Change. The Corporation also shall give prompt notice of the closing
or  consummation  of such  Fundamental  Change to all  holders  of record of the
Series B Preferred as of the date of such closing or  consummation.  Each holder
of Series B Preferred shall thereupon promptly surrender for conversion,  to the
Corporation  at its principal  office or to any transfer  agent for the Series B
Preferred  or the Common  Stock,  all  certificates  representing  all shares of
Series  B  Preferred  held by  such  holder,  accompanied  by a  written  notice
specifying the name or names in which such holder wishes the  certificate(s) for
shares of Common Stock to be issued.

                  (i) Certificate as to Adjustments;  Notice by Corporation.  In
each case of an  adjustment or  readjustment  of the Original  Issue Price,  the
Corporation  at its expense  will  furnish  each holder of Series B Preferred so
affected with a certificate  prepared by an officer of the Corporation,  showing
such adjustment or readjustment, and stating in detail the facts upon which such
adjustment or readjustment is based.

                  (j)  Exercise  of  Conversion   Privilege.   To  exercise  its
conversion  privilege,  a holder of Series B Preferred shall give written notice
by telecopy to the  Corporation at its principal  office that such holder elects
to convert shares of its Series B Preferred and shall  thereafter  surrender the
original   certificate(s)   representing  the  shares  being  converted  to  the
Corporation at its principal office together with an originally executed copy of
such notice. Such notice shall also state the name or names (with its address or

                                      A-8
<PAGE>
addresses,  as well as the address(es) for delivery) in which the certificate(s)
for shares of Common Stock issuable upon such  conversion  shall be issued.  The
certificate(s)  for the shares of Series B Preferred  surrendered for conversion
shall be  accompanied  by proper  assignment  thereof to the  Corporation  or in
blank. As promptly as practicable  after the  Corporation  receives the original
certificate(s) for the shares of Series B Preferred  surrendered for conversion,
the proper  assignment  thereof to the  Corporation or in blank and the original
notice of conversion  (collectively,  the "Original  Documentation"),  but in no
event more than three (3) trading  days after the  Corporation's  receipt of the
Original Documentation, the Corporation shall issue and deliver to the holder of
the shares of Series B Preferred  being  converted,  at the  addresses set forth
therefor by the holder,  such certificate(s) as it may request for the number of
whole  shares of Common Stock  issuable  upon the  conversion  of such shares of
Series B Preferred in  accordance  with the  provisions  of this Section 5. Such
conversion shall be deemed to have been effected  immediately prior to the close
of business on the Conversion Date, and at such time the rights of the holder as
holder  of the  converted  shares  of  Series B  Preferred  shall  cease and the
person(s) in whose name(s) any  certificate(s)  for shares of Common Stock shall
be issuable upon such conversion shall be deemed to have become the holder(s) of
record of the shares of Common Stock  represented  thereby.  If the  Corporation
fails to issue and  deliver to such  holder  such  certificate(s)  for shares of
Common Stock within  three (3) trading days after the  Corporation's  receipt of
the Original Documentation, the Corporation shall pay the liquidated damages set
forth in Section 5 of the Stock Purchase  Agreement  between the Corporation and
the purchasers of the Series B Preferred (the "Stock  Purchase  Agreement").  No
issuance of shares in any name other than the original  holder shall be effected
unless such transfer is in compliance with the transfer  restrictions  contained
in the Stock Purchase Agreement.

                  (k) Fractional Shares. No fractional shares of Common Stock or
scrip  representing  fractional  shares shall be issued upon the  conversion  of
shares of Series B Preferred.  Instead of any fractional  shares of Common Stock
that would  otherwise be issuable  upon  conversion  of Series B Preferred,  the
number of shares  issuable  upon  conversion  shall be rounded up or down to the
nearest whole share, with fractional shares of 0.5 or greater being rounded up.

                  (l) Partial  Conversion.  In the event some but not all of the
shares of Series B Preferred  represented by a  certificate(s)  surrendered by a
holder are  converted,  the  Corporation  shall execute and deliver to or on the
order of the  holder,  at the  expense  of the  Corporation,  a new  certificate
representing  the  number  of  shares  of  Series  B  Preferred  which  were not
converted.  Such new  certificate  shall be so delivered on or prior to the date
set forth in Section 5(j) for the delivery of certificates  for shares of Common
Stock.

                  (m) Reservation of Common Stock. The Corporation  shall at all
times reserve and keep available out of its  authorized  but unissued  shares of
Common Stock,  solely for the purpose of effecting the  conversion of the shares
of the Series B Preferred,  150% of such number of its shares of Common Stock as
shall  from  time  to  time  be  sufficient  to  effect  the  conversion  of all
outstanding  shares of the Series B Preferred  (including any shares of 

                                      A-9
<PAGE>
Series  B  Preferred  represented  by any  warrants,  options,  subscription  or
purchase  rights for the Series B  Preferred),  and if at any time the number of
authorized  but unissued  shares of Common Stock shall not be 150% of the number
of such  shares  sufficient  to effect the  conversion  of all then  outstanding
shares of the Series B  Preferred  (including  any shares of Series B  Preferred
represented by any warrants,  options,  subscriptions or purchase rights for the
Series B Preferred),  then the  Corporation  shall be deemed to be in breach and
default of its obligations hereunder, and in addition to all charges, claims and
rights  at law  or in  equity  that  each  holder  shall  be  entitled  to,  the
Corporation  shall use all means  reasonably  available to it, and promptly take
any and all actions as may be necessary, to increase its authorized but unissued
shares of Common  Stock to such  number of shares as shall be 150% of the amount
sufficient for such purpose.


         6.  Redemption and Repurchase Rights.  
             --------------------------------  

     The  Corporation  shall  have no right to redeem  and  holders of shares of
Series B Preferred shall have no right to cause the  Corporation to redeem,  any
or all of the outstanding shares of Series B Preferred, except as follows:

                  (a) if a  holder  of  shares  of  Series B  Preferred  submits
Original  Documentation  relating  to the  conversion  of  shares  of  Series  B
Preferred in the manner provided for in Section 5(j) and the number of shares of
Common Stock issuable upon such conversion is limited by reason of the Share Cap
described in Section 5(d)(ii), the Corporation shall, on demand of any holder of
Series B Preferred, redeem any portion of the Series B Preferred not exercisable
as a result of such  limitation  at a redemption  price equal to $1.25 per share
plus  accrued  dividends  (the  "Share  Cap  Redemption  Price").  The Share Cap
Redemption Price shall be payable within five (5) business days after demand for
such redemption is made.

                  (b) if (i) the  Registration  Statement  is not  filed  within
sixty (60) days from the  Closing  Date (as defined in the  Registration  Rights
Agreement) or (b) the Required  Effective  Date (as defined in the  Registration
Rights Agreement) is greater than one hundred fifty (150) days after the Closing
Date, or (c) the  effectiveness of the Registration  Statement is not maintained
during the Registration Period (as defined in the Registration Rights Agreement)
each  holder may,  at its  option,  require the Company to redeem the  Preferred
Shares in full,  within  three (3) days,  in cash,  at the Share Cap  Redemption
Price.


                  (c) in the  event  that  the  Company  does not  register  the
Preferred  Stock  within  150 days  after the  Closing  Date (as  defined in the
Registration Rights Agreement),  as more particularly  described in Section 2 of
the Registration Rights Agreement, the Company shall redeem the Preferred Shares
at the Share Cap  Redemption  Price within three (3) business  days after it has
received  demand for such redemption from the holders of the Series B Preferred.
In exercising its rights hereunder or pursuant to Section 6(a) above the holders
can  individually  exercise  their  respective  redemption  rights  without  the
participation 

                                      A-10
<PAGE>
of the other holders.


         7. Notices of Record Date. In the event of any:
            -----------------------------------------------

                  (a) taking by the  Corporation  of a record of the  holders of
any class of securities for the purpose of determining  the holders  thereof who
are  entitled to receive any  dividend  or other  distribution,  or any right to
subscribe for,  purchase or otherwise acquire any shares of capital stock of any
class or any other securities or property, or to receive any other right, or

                  (b)   capital   reorganization   of   the   Corporation,   any
reclassification  or  recapitalization  of the capital stock of the Corporation,
any  merger or  consolidation  of the  Corporation,  or any  transfer  of all or
substantially all of the assets of the Corporation to any other Corporation,  or
any other entity or person, or

                  (c)      voluntary  or involuntary dissolution, liquidation or
winding up of the Corporation, then and in each such event the Corporation shall
telecopy  and  thereafter  mail or cause to be mailed to each holder of Series B
Preferred  a notice  specifying  (i) the date on which any such  record is to be
taken for the purpose of such dividend,  distribution or right and a description
of such  dividend,  distribution  or  right,  (ii) the  date on  which  any such
reorganization,  reclassification,  recapitalization,  transfer,  consolidation,
merger, dissolution,  liquidation or winding up is expected to become effective,
and (iii) the time,  if any,  that is to be  fixed,  as to when the  holders  of
record of Common Stock (or other securities) shall be entitled to exchange their
shares of Common Stock (or other  securities)  for  securities or other property

receipt,  from the  holder  of any  certificate  evidencing  shares  of Series B
Preferred,  of evidence reasonably satisfactory to the Corporation (an affidavit

destruction or mutilation of such certificate, and in the case of any such loss,
theft or destruction,  upon receipt of indemnity reasonably  satisfactory to the
Corporation,  and in the case of any such  mutilation,  upon  surrender  of such

the  aforesaid  notice (A) all  transfer  taxes and other  governmental  charges
payable upon the issuance or delivery of securities in such other name(s) or (B)
evidence  satisfactory to the Corporation  that such taxes and charges have been

Annex II (the "Joint Escrow  Instructions").  No later than the Closing Date (as
defined below), the Company shall deliver one or more certificates  representing
the Preferred  Stock duly executed on behalf of the Company  (collectively,  the

                  2.  BUYER   REPRESENTATIONS,   WARRANTIES,   ETC.;  ACCESS  TO
INFORMATION; INDEPENDENT INVESTIGATION.

                  Each Buyer  represents  and  warrants  to, and  covenants  and
agrees with, the Company as follows:

                  a.  Without  limiting  Buyer's  right to sell the Common Stock
pursuant  to  the  Registration  Statement  (as  that  term  is  defined  in the
Registration  Rights  Agreement  defined  below),  the Buyer is  purchasing  the
Preferred  Stock and will be acquiring the shares of Common Stock  issuable upon
conversion of the Preferred Stock (the  "Converted  Shares") for its own account
for  investment,  and not with a view  towards the public  sale or  distribution
thereof and not with a view to or for sale in connection  with any  distribution
thereof.

                  b. The Buyer is (i) an  "accredited  investor" as that term is
defined in Rule 501 of the General Rules and  Regulations  under the 1933 Act by
reason of Rule  501(a)(3),  (ii)  experienced in 

                                       2
<PAGE>
making  investments  of the kind  described  in this  Agreement  and the related
documents, (iii) able, by reason of the business and financial experience of its
officers (if an entity) and  professional  advisors (who are not affiliated with
or  compensated  in any way by the Company or any of its  affiliates  or selling
agents),  to protect  its own  interests  in  connection  with the  transactions
described in this Agreement,  and the related documents, and (iv) able to afford
the entire loss of its investment in the Securities.

                  c. All subsequent  offers and sales of the Preferred Stock and
the shares of Common Stock  representing the Converted Shares (such Common Stock
sometimes  referred to as the  "Shares") by the Buyer shall be made  pursuant to
registration  of the Shares under the 1933 Act or pursuant to an exemption  from
registration.

                  d. The Buyer  understands  that the Preferred  Stock are being
offered and sold to it in reliance on specific  exemptions from the registration
requirements  of United States  federal and state  securities  laws and that the
Company is relying upon the truth and  accuracy  of, and the Buyer's  compliance
with,  the   representations,   warranties,   agreements,   acknowledgments  and
understandings  of the  Buyer  set  forth  herein  in  order  to  determine  the
availability  of such exemptions and the eligibility of the Buyer to acquire the
Preferred Stock.

                  e. The Buyer and its  advisors,  if any,  have been  furnished
with all  materials  relating to the  business,  finances and  operations of the
Company and materials  relating to the offer and sale of the Preferred Stock and
the offer of the Shares which have been requested by the Buyer,  including Annex
V hereto. The Buyer and its advisors, if any, have been afforded the opportunity
to ask  questions of the Company and have  received  complete  and  satisfactory
answers to any such inquiries. Without limiting the generality of the foregoing,
the Buyer has also had the opportunity to obtain and to review (i) the Company's
annual  report  on Form  10-KSB  for the year  ending  June 30,  1998,  (ii) the
Company's  reports on Form 10-QSB for the periods ending  September 30, 1998 and
December 31, 1998 (the "SEC Reports");

                  f.       The  Buyer  understands  that  its investment in  the
Securities involves a high degree of risk.

                  g. The Buyer  understands  that no United  States  federal  or
state agency or any other  government  or  governmental  agency has passed on or
made any recommendation or endorsement of the Securities.

                  h.  This  Agreement  has  been  duly and  validly  authorized,
executed  and  delivered  on behalf  of the  Buyer  and is a valid  and  binding
agreement of the Buyer  enforceable in accordance with its terms,  subject as to
enforceability  to general  principles of equity and to bankruptcy,  insolvency,
moratorium and other similar laws affecting the enforcement of creditors' rights
generally.

                  i.  Notwithstanding  the provisions hereof or of the Preferred
Stock,  in no event  (except  with  respect to an  automatic  conversion  of the
Preferred Stock as provided in the Certificate of Designations) shall each Buyer
be  entitled  to convert  any  Preferred  Stock to the extent  that,  after such
conversion,  the sum of (1) the  number of shares of Common  Stock  beneficially
owned by such Buyer and its affiliates  (other than shares of Common Stock which
may be deemed  beneficially  owned  through  the  

                                       3
<PAGE>
ownership of the unconverted portion of the Preferred Stock), and (2) the number
of shares of Common Stock  issuable upon the  conversion of the Preferred  Stock
with respect to which the  determination  of this  proviso is being made,  would
result in  beneficial  ownership by such Buyer and its  affiliates  of more than
4.99% of the outstanding  shares of Common Stock. For purposes of the proviso to
the immediately preceding sentence,  beneficial ownership shall be determined in
accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended
(the "1934  Act").  Any  issuance  by the  Company to the Buyer in excess of the
limit  contained in this Paragraph  3.i. shall be null and void, ab initio,  and
upon notice of such invalid  issuance,  the Company  shall correct its books and
cause its transfer  agent's books to be corrected  forthwith to reflect that the
Buyer's  ownership of Common Stock is within the limit set forth  herein.  Buyer
shall immediately  deliver any certificates for invalidly issued Common Stock to
the Company's  transfer  agent.  The Company  further agrees to (i)  immediately
reissue certificates for Common Stock to the extent that a portion of the Common
Stock  represented  by said  certificates  have  been  validly  issued  and (ii)
immediately reissue all or a portion of those shares which were deemed invalidly
issued (at a price set forth in the original  conversion  notices  applicable to
such shares) upon notice from the Buyer that the reissuance of such shares would
not cause such Buyer to have a beneficial ownership interest in excess of 4.99%.
With respect to the foregoing,  the Company  acknowledges and agrees that, it is
aware that some of the  Buyers of the  Securities  may have the same  investment
advisor or  "sub-advisor"  and that, based on such limited  relationship  alone,
such  entities  are  not a group  for the  purposes  of  determining  beneficial
ownership  pursuant to Sections 13(d) and 16 of the 1934 Act. The Company hereby
indemnifies  and holds each Buyer free and harmless in  connection  with any and
all liabilities,  losses,  costs and expenses,  including,  without  limitation,
attorneys'  fees and costs  arising from or relating to claims made by any third
parties with  respect to any and all  purported  violations  by each Buyer under
Sections 13(d) and 16 resulting from a conversion(s) of Preferred Stock,  unless
such claim arises from such Buyer's  default of its  obligations  hereunder,  or
representations or warranties contained herein.


                  j. Buyer  represents  that it neither is nor will be obligated
for any finders' fee or commission nor is it aware of any such fee or commission
payable in connection with this transaction other than as set forth on the Joint
Escrow Instructions (attached hereto as Annex II). Buyer agrees to indemnify and
to  hold  harmless  the  Company  from  any  liability  for  any  commission  or
compensation  in the nature of a  finders'  fee (and the costs and  expenses  of
defending against such liability or asserted  liability) for which such Buyer or
any of its officers, partners, employees, or representatives is responsible.

                  3.       COMPANY REPRESENTATIONS, ETC.

                  The Company  represents and warrants and hereby  covenants and
agrees with each Buyer that:

                  a.  Concerning  the  Preferred  Stock  and  the  Shares.   The
Preferred  Stock has been duly  authorized  and,  when issued,  will be duly and
validly issued,  fully paid and  non-assessable  and will not subject the holder
thereof  to  personal  liability  by reason of being such  holder.  There are no
preemptive  rights of any  stockholder  of the Company,  as such, to acquire the
Preferred Stock or the Shares.
                                       4
<PAGE>
                  b. Reporting Company Status. The Company is a corporation duly
organized,  validly existing and in good standing under the laws of the State of
Colorado and has the  requisite  corporate  power to own its  properties  and to
carry on its business as now being conducted. The Company is duly qualified as a
foreign  corporation to do business and is in good standing in each jurisdiction
where the nature of the business  conducted  or property  owned by it makes such
qualification necessary,  other than those jurisdictions in which the failure to
so qualify would not have a material adverse effect on the business,  operations
or  prospects  or  condition  (financial  or  otherwise)  of the Company and its
subsidiaries,  taken as a whole.  The Company has  registered  its Common  Stock
pursuant  to  Section  12 of the 1934 Act,  and the  Common  Stock is listed and
traded on the NASDAQ/Bulletin  Board market. The Company has received no notice,
either oral or written,  with respect to the continued eligibility of the Common
Stock for such listing,  and the Company has maintained all requirements for the
continuation of such listing.

                  c.  Authorized  Shares.  The  Company  has at March 31,  1999,
14,410,689 shares of Common Stock outstanding, and has sufficient authorized and
unissued  Shares as may be reasonably  necessary to effect the conversion of the
Preferred  Stock  (assuming  all future  conversions  occurred are based upon an
average  5-day closing bid of the Common  Stock,  as reported by  Bloomberg,  LP
which was  one-half  (1/2) of the closing  bid price of the Common  Stock on the
Closing Date [the  "Closing Date Bid"]) and exercise of the Warrants (as defined
in  Section  4.j.) at the  Closing  Date  Bid.  The  Common  Stock has been duly
authorized and, when issued upon conversion of the Preferred Stock in accordance
with its terms, will be duly and validly issued,  fully paid and  non-assessable
and will not subject the holder thereof to personal liability by reason of being
such holder.

                  d.  Securities   Purchase   Agreement;   Registration   Rights
Agreement and Stock. This Agreement and the Registration  Rights Agreement,  the
form  of  which  is  attached  hereto  as  Annex  IV (the  "Registration  Rights
Agreement"),  and the transactions  contemplated  hereby and thereby,  have been
duly and  validly  authorized  by the  Company,  this  Agreement  has been  duly
executed and  delivered by the Company and this  Agreement is, and the Preferred
Stock, and the Registration Rights Agreement,  when executed and delivered by or
on behalf of the Company,  will be, valid and binding  agreements of the Company
enforceable  in  accordance  with  their  respective  terms,   subject,   as  to
enforceability,  to general principles of equity and to bankruptcy,  insolvency,
moratorium,  and other  similar laws  affecting  the  enforcement  of creditors'
rights generally.

                  e.  Non-contravention.  The  execution  and  delivery  of this
Agreement and the Registration Rights Agreement by the Company,  the issuance of
the Securities,  and the  consummation by the Company of the other  transactions
contemplated by this  Agreement,  the  Registration  Rights  Agreement,  and the
Preferred  Stock do not and will not conflict  with or result in a breach by the
Company of any of the terms or provisions  of, or constitute a default under (i)
the articles of  incorporation  or by-laws of the Company,  each as currently in
effect,  (ii) except as disclosed in Annex V, any indenture,  mortgage,  deed of
trust, or other material agreement or instrument to which the Company is a party
or by which it or any of its  properties  or assets  are  bound,  including  any
listing  agreement for the Common Stock  (except as herein set forth),  (iii) to
its  knowledge,  any  existing  applicable  law,  rule,  or  regulation  or  any
applicable  decree,  judgment,  or order of any court,  United States federal or
state regulatory body,  administrative agency, or other governmental body having
jurisdiction  over the Company or any of its  properties or assets,  or (iv) any
listing agreement for its Common Stock, except such conflict,  breach or default
which 

                                       5
<PAGE>
would  not have a  material  adverse  effect  on the  transactions  contemplated
herein.
                  f.  Approvals.  No  authorization,  approval or consent of any
court, governmental body, regulatory agency,  self-regulatory  organization,  or
stock  exchange or market or the  stockholders  of the Company is required to be
obtained by the Company for the issuance and sale of the Securities to the Buyer
as  contemplated by this Agreement,  except such  authorizations,  approvals and
consents that have been obtained.

                  g. SEC Filings.  None of the Company's SEC Reports  contained,
at the time they were filed,  any untrue statement of a material fact or omit to
state any material fact  required to be stated  therein or necessary to make the
statements  made  therein in light of the  circumstances  under  which they were
made, not misleading, except as corrected by an amended filing made prior to the
date hereof.  Except as set forth on Annex V hereto,  the Company has since June
1997 timely filed all  requisite  forms,  reports and exhibits  thereto with the
SEC.,

                  h. Absence of Certain Changes.  Since December 31, 1998, there
has been no material adverse change and no material  adverse  development in the
business, properties, operations, condition (financial or otherwise), or results
of operations of the Company and its subsidiaries,  taken as a whole,  except as
disclosed in Annex V or in the Company's SEC Reports.  Since  December 31, 1998,

payment or distribution  of cash or other property to stockholders  with respect
to its capital  stock,  or  purchased  or redeemed,  or made any  agreements  to
purchase or redeem,  any shares of its  capital  stock;  (iv) sold,  assigned or
transferred any other tangible assets,  or canceled any debts or claims,  except
in the ordinary course of business consistent with past practices;  (v) suffered
any substantial losses or waived any rights of material value, whether or not in
the ordinary course of business,  or suffered the loss of any material amount of
existing business; (vi) made any changes in employee compensation, except in the
ordinary course of business consistent with past practices; or (vii) experienced
any material  problems with labor or management in connection with the terms and
conditions of their employment.

                  i.  Full  Disclosure.  There is no fact  known to the  Company
(other than  general  economic  conditions  known to the public  generally or as
disclosed in the Company's SEC Reports),  that has not been disclosed in writing
to the Buyer that (i) would  reasonably  be expected to have a material  adverse
effect on the  business  or  financial  condition  of the  Company or (ii) would
reasonably  be expected to materially  and  adversely  affect the ability of the
Company to perform  its  obligations  pursuant to this  Agreement  or any of the
agreements  contemplated  hereby  (collectively,  including this Agreement,  the
"Transaction Agreements").

                  j.  Absence  of  Litigation.  Except  as set  forth in Annex V
hereto, and in the Company's SEC Reports, which the Buyer has reviewed, there is
no action,  suit,  proceeding,  inquiry or investigation before or by any court,
public  board or body pending or, to the  knowledge  of the Company,  threatened
against or affecting the Company,  wherein an  unfavorable  decision,  ruling or
finding  would 

                                       6
<PAGE>
have  a  material  adverse  effect  on the  properties,  business  or  financial
condition. results of operation or prospects of the Company and its subsidiaries
taken  as a whole or the  transactions  contemplated  by any of the  Transaction
Agreements or which would adversely affect the validity or enforceability of, or
the authority or ability of the Company to perform its obligations under, any of
the Transaction Agreements.

                  k. Absence of Events of Default.  Except as set forth in Annex
V hereto,  no Event of  Default  (or its  equivalent  term),  as  defined in the
respective  agreement to which the Company is a party, and no event which,  with
the giving of notice or the  passage of time or both,  would  become an Event of
Default (or its equivalent term) (as so defined in such agreement), has occurred
and is continuing,  which would have a material  adverse effect on the Company's
financial condition or results of operations.

                   l. Prior  Issues.  Except as set forth in Annex V, during the
twelve (12) months  preceding  the date  hereof,  the Company has not issued any
Common Stock or convertible  securities in capital  transactions  which have not
been fully disclosed in the Company's  filings with the SEC. Except as set forth
in Annex V, all such  issuances  (except for issuances to Buyer) have been fully
converted into shares of common stock and there are no  outstanding  unconverted
debt or convertible securities from those transactions.

                  m. No Undisclosed  Liabilities or Events.  Except as set forth
in Annex V, the  Company  has no  liabilities  or  obligations  other than those
disclosed in the Company's SEC Reports or those incurred in the ordinary  course
of the Company's business since December 31, 1998, and which, individually or in
the  aggregate,  do not or  would  not have a  material  adverse  effect  on the
properties,  business, condition (financial or otherwise), results of operations
or prospects of the Company and its subsidiaries,  taken as a whole. No event or
circumstances  has  occurred  or  exists  with  respect  to the  Company  or its
properties,  business, condition (financial or otherwise), results of operations
or prospects,  which, under applicable law, rule or regulation,  requires public
disclosure or announcement prior to the date hereof by the Company but which has
not been so publicly announced or disclosed.

                  n. No Default.  Except as disclosed  in Annex V,  hereto,  the
Company is not in default  in the  performance  or  observance  of any  material
obligation,  agreement,  covenant  or  condition  contained  in  any  indenture,
mortgage, deed of trust or other material instrument or agreement to which it is
a party or by which it or its property is bound.

                  o. No Integrated Offering.  Neither the Company nor any of its
affiliates  nor any  person  acting  on its or their  behalf  has,  directly  or
indirectly,  made any offer or sales of any security or solicited  any offers to
buy any security under  circumstances  that would eliminate the  availability of
the exemption from registration  under Regulation D in connection with the offer
and sale of the Securities as contemplated hereby.

                  p. Dilution.  The number of Shares issuable upon conversion of
the  Preferred  Stock  may  increase  substantially  in  certain  circumstances,
including,  but not necessarily limited to, the circumstance wherein the trading
price of the Common Stock  declines  prior to the  conversion  of the  Preferred
Stock.  The Company's  executive  officers and directors  have studied and fully
understand  the nature of the  Securities  being sold hereby and recognize  that
they have a potential dilutive effect. The board of directors of the Company has
concluded  that, in its good faith  business  judgment,  such issuance is in the
best interests of the Company.  The Company  specifically  acknowledges that its
obligation to issue the Shares upon conversion of the Preferred Stock is binding
upon the Company and  enforceable  regardless  of the dilution such issuance may
have on the ownership interests of other shareholders of the Company.

                  q. Acknowledgment by Company.  Company represents and warrants
that neither the Buyer,  nor any persons or entities  representing or purporting
to represent  the Buyer have made any  representation  or warranty  which is not
contained  expressly  in this  Agreement  or any other  agreements  referred  to
herein. Without limiting the foregoing,  Company specifically  acknowledges that
the Buyer has made no  representations  that it is a "long term" investor in the
Company,  or that it intends to hold the  Preferred  Stock or shares of stock in
the Company  (obtained by  conversions  of the  Preferred  Stock) for any period
beyond  that  which is  required  under  the  Securities  Act.  Company  further
acknowledges  that the Buyer may hedge the shares of stock in the Company  prior
to or after the  conversions of any of the Preferred  Stock,  provided that such
hedging is done in compliance with the Securities Act,  Securities Exchange Act,
any rules  applicable to securities  traded on the "OTC Bulletin  Board" and the
express  terms  of  this  Agreement,  the  Certificate  of  Designation  for the
Preferred Stock and the Registration Rights Agreement.

                  r. Brokers Fee. The Company  represents that it neither is nor
will be obligated for any finders' fee or commission nor is it aware of any such
fee or commission  payable in connection with this transaction other than as set
forth on the  Joint  Escrow  Instructions  (attached  hereto as Annex  II).  The
Company  agrees to indemnify  and to hold  harmless the Buyer from any liability
for any  commission  or  compensation  in the nature of a finders'  fee (and the
costs and expenses of defending  against such  liability or asserted  liability)
for  which  the  Company  or  any  of  its  officers,  partners,  employees,  or
representatives is responsible.

                  4.       CERTAIN COVENANTS AND ACKNOWLEDGMENTS.

                  a. Transfer Restrictions.  The Buyer acknowledges that (1) the
Preferred Stock has not been and is not being registered under the provisions of
the 1933 Act and, except as provided in the Registration  Rights Agreement,  the
Shares have not been and are not being  registered  under the 1933 Act,  and may
not be  transferred  unless (A)  subsequently  registered  thereunder or (B) the
Buyer shall have  delivered  to the  Company an opinion of  counsel,  reasonably
satisfactory in form, scope and substance to the Company, to the effect that the
Securities to be sold or transferred  may be sold or transferred  pursuant to an
exemption  from  such  registration;  (2)  any  sale of the  Securities  made in
reliance  on Rule  144  promulgated  under  the  1933  Act  may be made  only in
accordance  with  the  terms  of said  Rule  and  further,  if said  Rule is not
applicable,  any  resale of such  Securities  under  circumstances  in which the
seller,  or the  person  through  whom the sale is made,  may be deemed to be an
underwriter,  as that term is used in the 1933 Act, may require  compliance with
some other  exemption under the 1933 Act or the rules and 

                                       8
<PAGE>
regulations  of the SEC  thereunder;  and (3)  neither the Company nor any other
person is under any obligation to register the  Securities  (other than pursuant
to the Registration  Rights  Agreement) under the 1933 Act or to comply with the
terms and conditions of any exemption thereunder.

                  b. Restrictive  Legend. The Buyer acknowledges and agrees that
the Preferred Stock and, until such time as the Common Stock has been registered
under the 1933 Act as contemplated by the Registration Rights Agreement and sold
pursuant  to  an  effective  Registration  Statement,   certificates  and  other
instruments  representing any of the Securities shall bear a restrictive  legend
in  substantially  the following form (and a  stop-transfer  order may be placed
against transfer of any such Securities):

                  THESE SECURITIES (THE  "SECURITIES")  HAVE NOT BEEN REGISTERED
                  UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE  "SECURITIES
                  ACT"), OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD
                  OR  OFFERED   FOR  SALE  IN  THE   ABSENCE  OF  AN   EFFECTIVE
                  REGISTRATION  STATEMENT  FOR THE  SECURITIES  OR AN OPINION OF
                  COUNSEL OR OTHER EVIDENCE  ACCEPTABLE TO THE CORPORATION  THAT
                  SUCH REGISTRATION IS NOT REQUIRED.

                  c. Registration Rights Agreement.  The parties hereto agree to
enter into the Registration Rights Agreement on or before the Closing Date.

                  d.  Filings.  The  Company  undertakes  and agrees to make all
necessary  filings in  connection  with the sale of the  Preferred  Stock to the
Buyer  under  any  United  States  laws  and  regulations,  or by  any  domestic
securities  exchange  or trading  market,  and to provide a copy  thereof to the
Buyer promptly after such filing.

                  e. Reporting  Status.  So long as the Buyer  beneficially owns
any of the Preferred  Stock,  the Company shall file all reports  required to be
filed with the SEC  pursuant  to  Section  13 or 15(d) of the 1934 Act,  and the
Company  shall not  terminate  its status as an issuer  required to file reports
under the 1934 Act even if the 1934 Act or the rules and regulations  thereunder
would permit such termination.

                  f. Use of Proceeds. The Company will use the proceeds from the
sale of the  Preferred  Stock  (excluding  amounts paid by the Company for legal
fees,  finder's  fees and escrow agent fees in  connection  with the sale of the
Preferred  Stock)  for  general  capital  purposes  and,  without  limiting  the
foregoing,  shall not,  directly or  indirectly,  use any of such  proceeds  for
investment in any other affiliate.

                  g. Future Purchases.  Intentionally deleted.

                  h. Certain  Agreements.  (i) The Company  covenants and agrees
that it will not, without the prior written consent of the Buyer, enter into any
subsequent or further  offer or sale of Common Stock or  securities  convertible
into Common Stock with any third party until one hundred eighty (180) days after
the Effective Date (as defined below).

                                       9
<PAGE>
                  (ii) The provisions of  subparagraph  (h)(i) will not apply to
(w)  Common  Stock  issued as  "restricted  stock" as  defined  in SEC Rule 144,
provided the holder  thereof  holds such Common Stock for at least one year from
the date of issuance;  (x) a secondary public offering of shares of Common Stock
at market; (y) an offering of convertible  debentures at market or above; or (z)
the issuance of securities  (other than for cash) in  connection  with a merger,
consolidation,  sale of assets, disposition or the exchange of the capital stock
for assets,  stock or other joint venture interests;  provided,  such securities
would not be included in the Registration Statement relating to the Shares and a
registration  statement  in respect of such  stock  shall not be filed  prior to
sixty (60) days after the Effective Date.

                  (iii) The term  "Effective  Date" means the effective  date of
the Registration  Statement  covering the Registrable  Securities (as defined in
the Registration Rights Agreement).

                  (iv) In the event the Company  breaches the provisions of this
Paragraph 4(h), the Conversion Price shall be amended to be the lesser of 75% of
the lowest two (2) day average closing bid (not necessarily consecutive) for the
fifteen (15) days prior to the  Conversion  Notice,  but at no time in excess of
100% of the fifteen (15) day average bid price prior to Closing,  and Buyer may,
within thirty (30) days after it receives written notice of such breach from the
Company,  require the Company to immediately  redeem all  outstanding  Preferred
Stock in accordance with Section 4(k)(y).

                  (v)  Notwithstanding  anything  contained in this Section,  it
shall not be a violation of this  Agreement for the Company to issue  additional
options  pursuant  to its 1992 Stock  Option  Plan,  and to issue  shares of its
Common Stock upon  exercise of any  presently  outstanding  option or warrant or
upon  conversion of, or as dividends on, Series A Preferred  Stock.  The Company
shall also be entitled to register any shares underlying  presently  outstanding
stock options on Form S-8, to the extent not  currently  covered by an effective
S-8 Registration Statement.

                  i.  Available  Shares.  The  Company  shall  have at all times
authorized and reserved for issuance,  free from  preemptive  rights,  shares of
Common Stock equal to one hundred fifty  percent  (150%) of the number of shares
of Common Stock  issuable upon  conversion of all of the  outstanding  Preferred
Stock, and the exercise of the Warrants (as defined below).

                  j.  Warrants.  The  Company  agrees  to  issue to Buyer at the
Closing,  transferable divisible warrants with cashless exercise provisions (the
"Warrants")  for 10,000  shares of Common Stock for each $50,000 of the Purchase
Price.  Such Warrants  shall bear an exercise price of $1.50 per share of Common
Stock, and shall be exercisable  immediately upon issuance,  and for a period of
five (5) years thereafter, in the form annexed hereto as Annex VI, together with
piggy-back  registration  rights,  and  demand  registration  rights  under  the
Registration Rights Agreement.

                  k.  Limitation  on  Issuance  of Shares.  The  Company  may be
limited  in the  number  of  shares  of  Common  Stock it may  issue by the "Cap
Regulations". Without limiting the other provisions thereof, the Preferred Stock
shall provide that (i) the Company will take all steps  reasonably  necessary to
be in a position to issue shares of Common Stock on  conversion of the Preferred
Stock and/or exercise of the Warrants without  violating the Cap Regulations and
(ii) if, despite taking such steps,  the Company still can not issue such shares
of Common  Stock  due upon a Notice  of  Conversion  without  violating  the Cap
Regulations  (each such share, an "Unconverted  Preferred  Stock"),  the Company
shall have the option,  
                                       10
<PAGE>
in its  discretion,  by notice within five (5) business days, to elect either of
the following remedies:

                  (x)  issue  shares  of Common  Stock in  accordance  with such
         holder's  notice of conversion at a conversion  purchase price equal to
         the average of the closing bid price per share of Common  Stock for the
         five  (5)  consecutive  trading  days  (subject  to  certain  equitable
         adjustments for certain events occurring during such period)  preceding
         the date of notice of conversion; or

                  (y) redeem each  Unconverted  Preferred Stock for an amount in
         cash (the "Redemption Amount") equal to:

                               V      x      125%
         where:

                  "V" means the  aggregate  Purchase  Price of such  Unconverted
         Preferred Stock plus any accrued but unpaid dividend thereon;

The Preferred Stock shall contain provisions  substantially  consistent with the
above  terms,  with such  additional  provisions  as may be  consented to by the
Buyer.  The  provisions of this paragraph are not intended to limit the scope of
the provisions otherwise included in the Preferred Stock.


                  5.       TRANSFER AGENT INSTRUCTIONS.

                   a.  Promptly  following  the  delivery  by the  Buyer  of the
aggregate purchase price for the Preferred Stock in accordance with Section 1(c)
hereof, the Company will irrevocably instruct its transfer agent to issue Common
Stock from time to time upon  conversion of the Preferred  Stock in such amounts
as specified from time to time by the Company to the transfer agent, bearing the
restrictive  legend  specified  in  Section  4(b) of  this  Agreement  prior  to
registration  of the Shares  under the 1933 Act,  registered  in the name of the
Buyer or its nominee and in such  denominations  to be specified by the Buyer in
connection with each  conversion of the Preferred  Stock.  The Company  warrants
that no instruction other than such  instructions  referred to in this Section 5
and stop  transfer  instructions  to give effect to Section 4(a) hereof prior to
registration  and  sale of the  Shares  under  the 1933 Act will be given by the
Company to the  transfer  agent and that the Shares  shall  otherwise  be freely
transferable  on the books  and  records  of the  Company  as and to the  extent
provided in this Agreement,  the Registration  Rights Agreement,  and applicable
law. Nothing in this Section shall affect in any way the Buyer's obligations and
agreement  to comply  with all  applicable  securities  laws upon  resale of the
Securities.  If the Buyer  provides  the  Company  with an  opinion  of  counsel
reasonably  satisfactory  to the Company  that  registration  of a resale by the
Buyer of any of the Securities in accordance  with clause (1)(B) of Section 4(a)
of this  Agreement is not required under the 1933 Act, the Company shall (except
as provided in clause (2) of Section 4(a) of this Agreement) permit the transfer
of the  Securities  and,  in the  case  of the  Shares,  promptly  instruct  the
Company's  transfer  agent to issue one or more  certificates  for Common  Stock
without legend in such name and in such denominations as specified by the Buyer.

                  b. (i) The Company will permit the Buyer to exercise its right
to convert the 

                                       11
<PAGE>
Preferred  Stock by telecopying  an executed and completed  Notice of Conversion
(as defined in the  Certificate  of  Designation)  to the Company and delivering
within three (3) business days  thereafter,  the original  Notice of Conversion,
together with the original share certificate, by express courier.

                           (ii) The term "Conversion  Date" means,  with respect
to any conversion elected by the
holder of the Preferred  Stock after the Effective  Date,  the date specified in
the  Notice of  Conversion,  provided  the copy of the Notice of  Conversion  is
telecopied  to or  otherwise  delivered  to the Company in  accordance  with the
provisions hereof so that is received by the Company on or before such specified
date. The Conversion Date for any mandatory  conversion at maturity shall be the
Maturity Date of the Preferred Stock.

                           (iii) The Company  shall,  at its  expense,  take all
actions and use all means necessary
and  diligent  to  cause  its  transfer  agent  to  transmit  the   certificates
representing  the  Shares  issuable  upon  conversion  of  any  Preferred  Stock
(together with Preferred  Stock not being so converted) to the Buyer via express
courier,  by electronic  transfer or  otherwise,  within three (3) business days
after  receipt by the  Company of the later of (i) receipt by the Company of the
copy of the original  Notice of Conversion and share  certificate,  and (ii) the
Conversion Date (the "Delivery Date").

                  c. The Company understands that a delay in the issuance of the
Shares of Common Stock beyond the Delivery Date could result in economic loss to
the Buyer. As compensation to the Buyer for such loss, the Company agrees to pay
late  payments to the Buyer in the event that due entirely to the  Corporation's
failure to issue and deliver the Shares upon  Conversion in accordance  with the
following  schedule (where "No.  Business Days Late" is defined as the number of
business days beyond five (5) business days from Delivery Date):

                                            Late Payment For Each $10,000
                                            of Preferred Stock Liquidation
        No. Business Days Late     Amount Being Converted             

                 1                           $100
                 2                           $200
                 3                           $300
                 4                           $400
                 5                           $500
                 >5                          $500 +$200 for each Business
                                             Day Late beyond 5 days from
                                             The Delivery Date

                  The Company shall pay any payments incurred under this Section
in  immediately  available  funds upon  demand.  Nothing  herein shall limit the
Buyer's  right to pursue  actual  damages or to cause the  Company to redeem the
Preferred  Shares as  provided  below for the  Company's  actions  or  inactions
resulting in the transfer  agent's failure to issue and deliver the Common Stock
to the  Buyer.  Furthermore,  in  addition  to any other  remedies  which may be
available  to the Buyer,  in the event that the  Company  fails to deliver  such
shares of Common Stock within five (5)  business  days after the Delivery  Date,
the Buyer  will be  entitled  to revoke the  relevant  Notice of  Conversion  by
delivering a notice to such 
                                       12
<PAGE>
effect to the Company whereupon the Company and the Buyer shall each be restored
to their respective  positions  immediately  prior to delivery of such Notice of
Conversion.  In the event  the  Company's  actions  or  inactions  result in the
transfer  agent's  failure to issue and  deliver  the Common  Stock to the Buyer
within ten (10) days after the Delivery Date, Buyer may, at its option,  require
the Company  (without  limiting its other  remedies  hereunder)  to  immediately
redeem all outstanding Preferred Stock in accordance with Section 4(k)(y).


                  d. If, by the relevant  Delivery  Date,  the Company fails for
any reason to deliver the Shares to be issued upon  conversion  of the Preferred
Stock and after such  Delivery  Date,  the holder of the  Preferred  Stock being
converted (a "Converting  Holder")  purchases,  in an open market transaction or
otherwise,  shares of Common  Stock  (the  "Covering  Shares")  in order to make
delivery in satisfaction of a sale of Common Stock by the Converting Holder made
after a Conversion  Date (the "Sold  Shares"),  which  delivery such  Converting
Holder anticipated to make using the Shares to be issued upon such conversion (a
"Buy-In"),  the Company shall pay to the Converting  Holder,  in addition to all
other amounts  contemplated in other  provisions of the Transaction  Agreements,
and not in lieu thereof,  the Buy-In Adjustment  Amount (as defined below).  The
"Buy-In Adjustment Amount" is the amount equal to the excess, if any, of (x) the
Converting Holder's total purchase price (including  brokerage  commissions,  if
any)  for  the  Covering  Shares  over  (y) the net  proceeds  (after  brokerage
commissions, if any) received by the Converting Holder from the sale of the Sold
Shares.  The  Company  shall pay the  Buy-In  Adjustment  Amount to the Buyer in
immediately available funds immediately upon demand by the Converting Holder. By
way of  illustration  and not in limitation of the foregoing,  if the Converting
Holder purchases shares of Common Stock having a total purchase price (including
brokerage  commissions)  of $11,000 to cover a Buy-In with  respect to shares of
Common Stock it sold for net proceeds of $10,000,  the Buy-In  Adjustment Amount
which Company will be required to pay to the  Converting  Holder will be $1,000.
The remedies set forth in paragraphs 5(c) and (d) shall be cumulative.

                  e. In lieu of delivering  physical  certificates  representing
the  unlegended  securities  issuable  upon  conversion,  provided the Company's
transfer agent is  participating  in the Depository  Trust Company  ("DTC") Fast
Automated  Securities  Transfer  program,  upon  request  of the  Buyer  and its
compliance  with the  provisions  contained  in this  paragraph,  so long as the
certificates  therefor  do not  bear a  legend  and  the  Buyer  thereof  is not
obligated to return such certificate for the placement of a legend thereon,  the
Company shall use its best efforts to cause its transfer agent to electronically
transmit the Common Stock issuable upon conversion to the Buyer by crediting the
account of Buyer's  Prime Broker with DTC through its Deposit  Withdrawal  Agent
Commission system.

                  f. The original  certificate  representing the Preferred Stock
shall be  delivered  by the  Buyer to the  Company  simultaneous  with the final
Notice of Conversion.

                  6.       DELIVERY INSTRUCTIONS.

                  The  Preferred  Stock shall be delivered by the Company to the
Escrow  Agent  pursuant to Section 1(b) hereof,  on a delivery  against  payment
basis, no later than on the Closing Date.

                  7.       CLOSING DATE.

                                    13
<PAGE>
                  (i) The  closing  of the  issuance  and sale of the  Preferred
Stock  shall  occur on the date (the  "Closing  Date")  which is the first  NYSE
trading day after the fulfillment or waiver of all closing  conditions  pursuant
to  Sections 8 and 9 hereof or such other  date and time as is  mutually  agreed
upon by the Company and the Buyer.

                  (ii) The closing of the  purchase  and  issuance of  Preferred
Stock shall occur on the Closing  Date,  at the offices of the Escrow  Agent and
shall take place no later than 12:00  Noon,  PST, on such day or such other time
as is mutually agreed upon by the Company and the Buyer.

                  (iii)  Notwithstanding  anything  to  the  contrary  contained
herein,  the Escrow Agent will be authorized to release the Escrow  Property (as
defined in the Escrow  Agreement)  only upon  satisfaction of the conditions set
forth in Sections 8 and 9 hereof.

                  8.       CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL.

                  The Buyer  understands  that the Company's  obligation to sell
the  Preferred  Stock on the  Closing  Date and to the  Buyer  pursuant  to this
Agreement is conditioned upon:

                  a. The receipt and  acceptance by the Buyer of this  Agreement
as  evidenced  by  execution  of this  Agreement  by the  Buyer for at least One
Million Five Hundred  Thousand  Dollars  ($1,500,000) in principal amount of the
Preferred Stock (or such lesser amount as the Company,  in its sole  discretion,
shall determine on the Closing Date);

                  b.  Delivery by the Buyer to the Escrow Agent of good funds as
payment in full of an amount equal to the Purchase Price for the Preferred Stock
in accordance with Section 1(c) hereof;

                  c. The accuracy on the Closing Date of the representations and
warranties  of the Buyer  contained in this  Agreement as if made on the Closing
Date,  and the  performance  by the Buyer on or before the  Closing  Date of all
covenants and  agreements of the Buyer required to be performed on or before the
Closing Date;

                  d. There  shall not be in effect any law,  rule or  regulation
prohibiting or restricting the transactions  contemplated  hereby,  or requiring
any consent or approval which shall not have been obtained.

                  9.       CONDITIONS TO THE BUYER'S OBLIGATION TO PURCHASE.

                  The  Company   understands  that  the  Buyer's  obligation  to
purchase the Preferred Stock on the Closing Date is conditioned upon:

                  a.       Acceptance  by the  Company of this Agreement for the
sale of Preferred Stock, as indicated by execution of this Agreement;

                                                  - Section 3.h.)

Capitalization:  On March 15, 1999,  the Company  completed  at $250,000  bridge
financing from an existing investor. The investor received a $250,000 promissory
note which bears interest at 10% per annum and is due at the earlier of June 12,
1999,  or receipt by the Company of proceeds  from a subsequent  financing of at
least $1 million.  The investor  received 50,000 shares of the Company's  Common
Stock and a fee equal to 12% of the proceeds of the investment.

Effective  March 19, 1999,  the Company and the  Burtzloff  Family Trust entered
into a Promissory Note Conversion and Stock Purchase  Agreement whereby $500,000
of notes payable plus accrued interest were converted into 598,213 shares of the
Company's Common Stock.

Effective  March 19, 1999,  the Company and Liviakis  Financial  Communications,
Inc.  entered into a Promissory  Note  Conversion and Stock  Purchase  Agreement

2,363,040 shares of the Company's Common Stock.

As of the end of March 1999, the Company has approximately  17,362,916 shares of
Common Stock outstanding. The Company expects to receive requests for conversion
of Series A Preferred Stock to Common Stock from existing  investors.  Currently
there are approximately  790,000 shares of Series A Preferred Stock outstanding,
which convert into Common Stock at 75% of market.

In  anticipation  of the close of  Financing  from Bold Street LLC,  the Company
received an advance of $200,000 on the first  funding via the execution of a 10%
Promissory  Note  which  will  be paid  back  at the  close  of  this  Series  B
transaction.

Company for personal reasons.  The Board of Directors is finalizing an agreement
with a new CEO candidate.  The compensation  package will include salary,  bonus
and a significant grant of performance based options or warrants.

In February  1999,  Charles  Russell  resigned  from the Board of Directors  for
health reasons.

Part  II,  Item 1, the  Company  reached  a  settlement  of  claims  of  certain
Noteholders  in  April  1998.  The  Company  is  considering  an  offer  from  a

restrictions  of Series A Preferred  shares).  As a condition of this financing,
the Company has negotiated a "Waiver of Rights and First  Amendment to Debenture
Agreement"  with the  Holders  of the 6%  Convertible  Debentures  that has been
reviewed by and is acceptable to Southridge Capital.

                              W I T N E S S E T H:

                  WHEREAS,  upon the terms and subject to the  conditions of the
Securities Purchase  Agreement,  dated as of April 30, 1999, between the Initial
Investors  and the Company (the  "Securities  Purchase  Agreement";  capitalized
terms not otherwise  defined herein shall have the meanings  ascribed to them in
the Securities Purchase Agreement),  the Company has agreed to issue and sell to
the  Initial  Investors  an  aggregate  of up to  5,000,000  shares  of Series B
Cumulative  Convertible  Redeemable  Preferred Stock, no par value,  $1.00 (plus
accrued dividends) liquidation preference of the Company (the "Preferred Stock,"
which  term,  as used  herein  shall  have  the  meaning  ascribed  to it in the
Securities Purchase Agreement); and

                  WHEREAS,  the Company has agreed to issue the  Warrants to the
Initial Investors in connection with the issuance of the Preferred Stock; and

                  WHEREAS,  the Preferred  Stock is  convertible  into shares of
Common  Stock  (the  "Conversion  Shares")  upon the  terms and  subject  to the
conditions contained in the Certificate of Designations; and

                  WHEREAS,  the  Warrants to be issued to the Initial  Investors
may be  exercised  for the  purchase  of shares of Common  Stock  (the  "Warrant
Shares") upon the terms and conditions of the Warrants; and

                  WHEREAS,  to induce  the  Initial  Investors  to  execute  and
deliver the  Securities  Purchase  Agreement,  the Company has agreed to provide
certain  registration  rights under the Securities Act of 1933, as amended,  and
the  rules  and  regulations  thereunder,   or  any  similar  successor  statute
(collectively,  the "Securities Act"), with respect to the Conversion Shares and
the Warrant Shares;

                  NOW,  THEREFORE,  in  consideration  of the  premises  and the
mutual covenants contained herein and other good and valuable consideration, the
receipt and  sufficiency of which are hereby  acknowledged,  the Company and the
Initial Investor hereby agree as follows:
<PAGE>
                  1.      Definitions.  As used in this Agreement, the following
terms shall have the following meanings:

                  (a) "Investors"  means the Initial Investors and any permitted
transferee  or assignee  who agrees to become  bound by the  provisions  of this
Agreement in accordance with Section 9 hereof.

                  (b) "Potential Material Event" means any of the following: (i)
the possession by the Company of material information not ripe for disclosure in
a registration  statement,  which shall be evidenced by  determinations  in good
faith  by the  Board  of  Directors  of the  Company  that  disclosure  of  such
information in the  registration  statement would be detrimental to the business
and affairs of the Company;  or (ii) any material  engagement or activity by the
Company which would, in the good faith  determination  of the Board of Directors
of the Company, be adversely affected by disclosure in a registration  statement
at  such  time,  which  determination  shall  be  accompanied  by a  good  faith
determination  by the Board of Directors  of the Company  that the  registration
statement  would  be  materially   misleading   absent  the  inclusion  of  such
information.

                  (c) "Register,"  "Registered," and  "Registration"  refer to a
registration  effected  by  preparing  and filing a  Registration  Statement  or
Statements in compliance  with the Securities Act and pursuant to Rule 415 under
the Securities Act or any successor rule providing for offering  securities on a
continuous  basis ("Rule 415"), and the declaration or ordering of effectiveness
of such  Registration  Statement by the United  States  Securities  and Exchange
Commission (the "SEC").

                  (d)      "Registrable Securities"  means the Conversion Shares
and the Warrant Shares.

                  (e) "Registration Statement" means a registration statement of
the Company under the Securities Act.

                  2.       Registration.

                  (a) Mandatory Registration. The Company shall prepare and file
with the SEC, as soon as  possible  after the  Closing  Date,  but no later than
thirty (30) days  following the Closing Date, a  Registration  Statement on Form
SB-2, registering for resale by the Investors all of the Registrable Securities,
but in no event less than two hundred percent (200%) of the aggregate  number of
shares into (i) which the Preferred  Stock would be  convertible  at the time of
filing of the Registration Statement (assuming for such purposes that all shares
of Preferred  Stock had been eligible to be converted,  and had been  converted,
into  Conversion  Shares in  accordance  with their  terms,  whether or not such
eligibility or conversion had in fact occurred as of such date),  and (ii) which
would be issued upon  exercise  of all of the  Warrants at the time of filing of
the  Registration  Statement  (assuming for such purposes that all such Warrants
had been  eligible to be exercised  and had been  exercised in  accordance  with
their terms, whether or not such eligibility or exercise had in fact occurred as
of such date). The  Registration  Statement shall also state that, in accordance
with  Rule  416  and  457  under  the  Securities   Act,  it  also  covers  such
indeterminate number of additional shares of Common Stock as may become issuable
upon conversion of the Preferred Stock and the exercise of the Warrants (and the
Existing  Warrants) to prevent  dilution  resulting from stock splits,  or stock
dividends.  The  Company  will use its  reasonable  best  efforts  to cause  the
Registration  Statement to be declared  effective no later than ninety days (90)
days after the Closing 

                                       2
<PAGE>
Date.  If at any time the  number  of  shares of  Common  Stock  into  which the
Preferred  Stock may be converted and which would be issued upon exercise of the
Warrants  equals more than  seventy  percent  (75%) of the  aggregate  number of
shares of Common  Stock then  registered,  the  Company  shall,  within ten (10)
business  days after receipt of a written  notice from any Investor,  either (i)
further amend the  Registration  Statement filed by the Company  pursuant to the
preceding  sentence,  if  such  Registration  Statement  has not  been  declared
effective  by the SEC at that time,  to register  200% of the  aggregate  of all
shares of Common Stock into which the Preferred  Stock may then or in the future
be converted and which would be issued  currently or in the future upon exercise
of the  Warrants,  or (ii) if such  Registration  Statement  has  been  declared
effective by the SEC at that time, file with the SEC an additional  Registration
Statement  on Form SB-2,  as may be  appropriate,  to  register  (A) 200% of the
aggregate shares of Common Stock into which the unconverted  Preferred Stock may
then or in the future be converted and which would be issued currently or in the
future upon exercise of the unexercised Warrants,  less (B) the aggregate number
of shares of Common  Stock  already  registered  which have not been issued upon
conversions  of Preferred  Stock or the exercise of Warrants.  The  Registration
Statement  shall not include any shares other than the  Registrable  Securities,
and certain  other shares that the Company is obligated to Register as set forth
in Schedule  5(b),  without the consent of all of the  Investors.  The  Investor
acknowledges  that  after the  closing  hereof  (but  prior to the filing of the
Registration  Statement)  up to five million  Preferred  Shares (less the amount
purchased  concurrently  herewith by the current  Investors)  may be sold by the
Company (and included on the  Registration  Statment) on the condition  that the
sale of such  Preferred  Shares is on the same terms which are  contained in the
Securities Purchase Agreement.

                  (b)      Payments by the Company.

                           (i)      If  the Registration  Statement covering the
Registrable  Securities  is not filed in  proper  form with the SEC on or before
thirty (30) days after the Closing Date (the "Required  Filing Date"),  then the
Company shall pay each Investor a late filing penalty (collectively "Late Filing
Penalties"),  (i) on the first day after the  Required  Filing  Date,  an amount
equal  to  three  percent  (3%)  of the  purchase  price  paid  pursuant  to the
Securities  Purchase  Agreement (the "Purchase  Price") for the Preferred  Stock
then  held by each  such  Investor  on such  date,  and (ii) on each  subsequent
monthly  anniversary of the Required Filing Date, if the Registration  Statement
has not been filed in proper  form on or before  such date,  an amount  equal to
three percent (3%) of the Purchase  Price for the  Preferred  Stock held by each
such Investor on each such subsequent monthly anniversary date.

                            (ii) If  the  Registration  Statement  covering  the
Registrable  Securities is not effective within the earlier of (a) five (5) days
after  notice by the SEC that it may be declared  effective,  or (b) ninety (90)
days  following  the Closing  Date (the  "Required  Effective  Date"),  then the
Company  shall pay each  Investor a late  effective  date penalty  (collectively
"Late  Effective  Date  Penalties")(sometimes  Late  Filing  Penalties  and Late
Effective  Penalties are collectively  referred to as "Late Penalties"),  (i) on
the first  day  after the  Required  Effective  Date,  an amount  equal to three
percent (3%) of the  Purchase  Price for the  Preferred  Stock then held by each
such Investor on such date and (ii) on each  subsequent  monthly  anniversary of
the Required Effective Date, if the Registration Statement has not been declared
effective  on or before such date,  an amount  equal to two percent  (2%) of the
Purchase  Price for the Preferred  Stock held by each such Investor on each such
subsequent monthly anniversary date.

                           (iii)  By way of  illustration  and not in limitation
of the  foregoing,  assuming  a  

                                       3
<PAGE>
Closing  Date of February 3, 2000 (X) if the  Registration  Statement  is timely
filed but is not  declared  effective  until  July 15,  2000  (assuming  for the
purpose of this example that the SEC has not previously  provided notice that it
may be declared effective), the aggregate Late Effective Date Penalty will equal
9% percent of the  Purchase  Price (3% on May 4, the 90th day after the  Closing
Date, plus 3% on June 3 and July 2) or (Y) if the Registration is filed on April
9 and is not declared  effective until May 15, 2000 (assuming for the purpose of
this  example  that the SEC has not  previously  provided  notice that it may be
declared  effective),  the  aggregate  Late Filing  Penalty will equal 6% of the
Purchase  Price (3% on March 5, the 30th day after the Closing Date,  plus 3% on
April 4) and the aggregate  Late Effective Date Penalty will equal 3% percent of
the Purchase Price (3% on May 4, the 90th day after the Closing Date).

                           (iv)      Additionally,   if  (a)  the   Registration
Statement  is not filed  within sixty (60) days from the Closing Date or (b) the
Required  Effective  Date is greater than one hundred fifty (150) days after the
Closing  Date, or (c) the  effectiveness  of the  Registration  Statement is not
maintained during the Registration Period as hereinafter defined,  each Investor
may, at its option,  require the Company to redeem the Preferred Shares in full,
within  three  (3)  days,  in  cash,  in  accordance  with  Section  6(b) of the
Certificate of Designation.

                           (v)       Late  Penalties  will  be  payable  to  the
Investor by the Company in cash or other immediately available funds on the date
such Late Penalty is incurred.

                           (vi)     The  parties  acknowledge  that  the damages
which may be incurred by the  Investors  if the  Registration  Statement  is not
filed by the Required Filing Date or if the Registration  Statement has not been
declared  effective  by the  Required  Registration  Date  may be  difficult  to
ascertain.  The parties  agree that the Late  Penalties  represent a  reasonable
estimate on the part of the parties,  as of the date of this  Agreement,  of the
amount of such damages. The payment of the Late Penalties to the Investors shall
not limit the Investors' other rights and remedies  hereunder or under any other
document entered into in connection herewith.

                           (vii)  Notwithstanding  the  foregoing,  the  amounts
payable by the Company  pursuant to this  provision  shall not be payable to the
extent  any delay in the  effectiveness  of the  Registration  Statement  occurs
because of an act of, or a failure to act or to act timely by the  Investors  or
their counsel if the Company timely  forwards to counsel any required  documents
or in the event all of the  Registrable  Securities may be sold pursuant to Rule
144 or another available exemption under the Act.

                  3.  Obligations  of  the  Company.   In  connection  with  the
registration  of the  Registrable  Securities,  the Company shall do each of the
following.
                  (a) Prepare  promptly,  and file with the SEC by the  Required
Filing Date, the Registration Statement with respect to not less than the number
of Registrable Securities provided in Section 2(a) above, and thereafter use its
reasonable  best  efforts  to cause  each  Registration  Statement  relating  to
Registrable  Securities to become  effective by the Required  Effective Date and
keep the Registration  Statement  effective at all times until the earliest (the
"Registration  Period")  of (i) the date that is two (2) years after the Closing
Date, (ii) the date when the Investors may sell all Registrable Securities under
Rule 144 or (iii) the date the  Investors  no longer own any of the  Registrable
Securities,   which   Registration   Statement   (including  any  amendments  or
supplements  thereto and prospectuses  contained  

                                       4
<PAGE>
therein)  shall not contain any untrue  statement of a material  fact or omit to
state a material  fact  required to be stated  therein or  necessary to make the
statements  therein,  in light of the circumstances in which they were made, not
misleading;

                  (b) Prepare and file with the SEC such  amendments  (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus  used  in  connection  with  the  Registration  Statement  as  may be
necessary  to  keep  the   Registration   effective  at  all  times  during  the
Registration  Period,  and,  during the  Registration  Period,  comply  with the
provisions  of  the  Securities  Act  with  respect  to the  disposition  of all
Registrable  Securities  of the Company  covered by the  Registration  Statement
until such time as all of such  Registrable  Securities have been disposed of in
accordance  with the intended  methods of  disposition  by the seller or sellers
thereof as set forth in the Registration Statement;

                  (c)  The  Company  shall  permit  a  single  firm  or  counsel
designated  by the  Investors  to  review  the  Registration  Statement  and all
amendments  and  supplements  thereto a reasonable  period of time (but not less
than three (3)  business  days) prior to their filing with the SEC, and not file
any document in a form to which such counsel reasonably objects.

                  (d)  Notify  the   Investors,   their   counsel  and  managing
underwriters,  if any,  immediately  (and, in the case of (i)(A) below, not less
than five (5) days prior to such  filing) and (if  requested by any such Person)
confirm such notice in writing no later than one (1) Business Day  following the
day (i)(A) when a Prospectus  or any  Prospectus  supplement  or  post-effective
amendment to the  Registration  Statement is proposed to be filed;  (B) whenever
the  Commission  notifies the Company  whether  there will be a "review" of such
Registration Statement; (C) whenever the Company receives (or representatives of
the  Company  receive  on its  behalf)  any oral or  written  comments  from the
Commission  in respect of a  Registration  Statement  (copies or, in the case of
oral  comments,  summaries of such comments  shall be promptly  furnished by the
Company to the Investors); and (D) with respect to the Registration Statement or
any post-effective  amendment,  when the same has become effective;  (ii) of any
request by the Commission or any other Federal or state  governmental  authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional  information;  (iii) of the  issuance by the  Commission  of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable  Securities or the initiation of any Proceedings for that
purpose;  (iv) if at any time any of the  representations  or  warranties of the
Company  contained  in any  agreement  (including  any  underwriting  agreement)
contemplated hereby ceases to be true and correct in all material respects;  (v)
of the receipt by the Company of any notification with respect to the suspension
of the  qualification or exemption from  qualification of any of the Registrable
Securities for sale in any jurisdiction, or the initiation or threatening of any
Proceeding for such purpose; and (vi) of the occurrence of any event that to the
best  knowledge  of the Company  makes any  statement  made in the  Registration
Statement  or  Prospectus  or  any  document   incorporated   or  deemed  to  be
incorporated  therein  by  reference  untrue  in any  material  respect  or that
requires  any  revisions  to the  Registration  Statement,  Prospectus  or other
documents so that, in the case of the Registration  Statement or the Prospectus,
as the case may be, it will not contain any untrue  statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.  In addition, the Company shall furnish the Investors with
copies of all intended written responses to the comments  contemplated in clause
(C) of this  Section  3(d) not later than one (1) Business Day in advance 

                                       5
<PAGE>
of the filing of such responses with the Commission so that the Investors  shall
have the opportunity to comment thereon.

                  (e) Furnish to each Investor whose Registrable  Securities are
included in the Registration  Statement and its legal counsel  identified to the
Company, (i) promptly after the same is prepared and publicly distributed, filed
with the SEC,  or  received  by the  Company,  one (1) copy of the  Registration
Statement,  each  preliminary  prospectus and prospectus,  and each amendment or
supplement  thereto,  and (ii) such  number of copies of a  prospectus,  and all
amendments and supplements  thereto and such other  documents,  as such Investor
may reasonably request in order to facilitate the disposition of the Registrable
Securities owned by such Investor;

                  (f) As promptly as  practicable  after  becoming aware of such
event,  notify each  Investor of the happening of any event of which the Company
has knowledge,  as a result of which the prospectus included in the 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, in light of the circumstances under which they were
made, not misleading,  and use its best efforts promptly to prepare a supplement
or amendment to the Registration  Statement or other appropriate filing with the
SEC to correct such untrue statement or omission, and deliver a number of copies
of such supplement or amendment to each Investor as such Investor may reasonably
request;

                  (g) As promptly as  practicable  after  becoming aware of such
event, notify each Investor who holds Registrable  Securities being sold (or, in
the  event  of an  underwritten  offering,  the  managing  underwriters)  of the
issuance by the SEC of a Notice of  Effectiveness or any notice of effectiveness
or any stop order or other  suspension of the  effectiveness of the Registration
Statement at the earliest possible time;

                  (h) Notwithstanding the foregoing, if at any time or from time
to time  after the date of  effectiveness  of the  Registration  Statement,  the
Company  notifies  the  Investors  in writing of the  existence  of a  Potential
Material  Event,   the  Investors  shall  not  offer  or  sell  any  Registrable
Securities,  or engage in any other  transaction  involving  or  relating to the
Registrable Securities,  from the time of the giving of notice with respect to a
Potential  Material Event until such Investor  receives  written notice from the
Company that such  Potential  Material  Event  either has been  disclosed to the
public or no longer constitutes a Potential Material Event;  provided,  however,
that the  Company may not so suspend  the right to such  holders of  Registrable
Securities for more than two twenty (20) day periods in the aggregate during any
12-month  period  ("Suspension  Period")  with at least a ten (10)  business day
interval between such periods,  during the periods the Registration Statement is
required to be in effect;

                  (i) Use its  reasonable  efforts  to  secure or  maintain,  as
applicable,  NASDAQ/OTC  Bulletin  Board  authorization  and  quotation for such
Registrable Securities and, without limiting the generality of the foregoing, to
arrange for at least two market makers to register with the National Association
of Securities  Dealers,  Inc.  ("NASD") as such with respect to such Registrable
Securities;

                  (j)  Provide a transfer  agent and  registrar,  which may be a
single entity, for the Registrable  Securities not later than the effective date
of the Registration Statement;

                                       6
<PAGE>
                  (k)  Cooperate   with  the  Investors  who  hold   Registrable
Securities  (or,  subject to receipt by the  Company of  appropriate  notice and
documentation,  as may be required by the  Securities  Purchase  Agreement,  the
Certificate  of  Designations,  the  Warrants  or  this  Agreement,   securities
convertible into Registrable  Securities) being offered to facilitate the timely
preparation  and delivery of certificates  for the Registrable  Securities to be
offered pursuant to the Registration  Statement and enable such certificates for
the Registrable  Securities to be in such  denominations  or amounts as the case
may be, as the Investors may reasonably request,  and, within three (3) business
days after a Registration  Statement  which includes  Registrable  Securities is
ordered  effective by the SEC, the Company shall deliver,  and shall cause legal
counsel  selected  by the  Company to  deliver,  to the  transfer  agent for the
Registrable   Securities  (with  copies  to  the  Investors  whose   Registrable
Securities or securities convertible into Registrable Securities are included in
such  Registration  Statement) an  appropriate  instruction  and opinion of such
counsel;  provided,  however,  that  nothing in this  subparagraph  (j) shall be
deemed to waive any of the  provisions  regarding  the  conditions  or method of
conversion  of  Preferred  Stock  or  exercise  of  Warrants  into   Registrable
Securities; and

                  (l) Take all other  reasonable  actions  necessary to expedite
and  facilitate  disposition  by  the  Investor  of the  Registrable  Securities
pursuant to the Registration Statement.

                  4.  Obligations  of the  Investors.  In  connection  with  the
registration  of the  Registrable  Securities,  each  Investor  shall  have  the
following obligations:

                  (a) As a condition precedent to the obligations of the Company
to complete  the  registration  pursuant to this  Agreement  with respect to the
Registrable Securities of a particular Investor,  such Investor shall furnish to
the Company such information  regarding itself, the Registrable  Securities held
by it, and the intended method of disposition of the Registrable Securities held
by it, as shall be  reasonably  required  to  effect  the  registration  of such
Registrable  Securities and shall execute such documents in connection with such
registration as the Company may reasonably request. At least five (5) days prior
to the first anticipated filing date of the Registration Statement,  the Company
shall notify each  Investor of the  information  the Company  requires from each
such Investor (the "Requested  Information") if such Investor elects to have any
of  such  Investor's   Registrable   Securities  included  in  the  Registration
Statement.  If at least  two (2)  business  days  prior to the  filing  date the
Company  has  not  received  the  Requested  Information  from  an  Investor  (a
"Non-Responsive Investor"), then the Company may file the Registration Statement
without including Registrable Securities of such Non-Responsive Investor;

                  (b) To cooperate  with the Company as reasonably  requested by
the Company in connection with the  preparation  and filing of the  Registration
Statement hereunder, unless such Investor has notified the Company in writing of
such  Investor's  election  to  exclude  all  of  such  Investor's   Registrable
Securities from the Registration Statement; and

                  (c)  Upon  receipt  of any  notice  from  the  Company  of the
happening of any event of the kind  described  in Section  3(e) or 3(f),  above,
such  Investor  shall   immediately   discontinue   disposition  of  Registrable
Securities  pursuant to the  Registration  Statement  covering such  Registrable
Securities  until such Investor's  receipt of the copies of the  supplemented or
amended  prospectus  contemplated by Section 3(e) or 3(f) and, if so directed by
the Company,  such Investor  shall deliver to the Company (at the expense of the
Company) or destroy (and deliver to the Company a  certificate  of  destruction)
all  copies in such  

                                       7
<PAGE>
Investor's  possession,  of the prospectus covering such Registrable  Securities
current at the time of receipt of such notice.

                  5.  Expenses  of  Registration.  (a) All  reasonable  expenses
(other than  underwriting  discounts and  commissions of each Investor and legal
fees of counsel to each  Investor)  incurred in connection  with  registrations,
filings or qualifications pursuant to Section 3, including,  without limitation,
all registration,  listing,  and  qualifications  fees,  printers and accounting
fees,  the fees and  disbursements  of counsel for the Company,  and a fee for a
single  counsel for the Investors not  exceeding  $3,500,  shall be borne by the
Company.

                  (b)  Except  as and to the  extent  specifically  set forth in
Schedule 5(b) attached  hereto,  neither the Company nor any of its subsidiaries
has, as of the date hereof,  nor shall the Company nor any of its  subsidiaries,
on or after the date of this Agreement, enter into any agreement with respect to
its  securities  that is  inconsistent  with the rights granted to the Investors
herein or otherwise  conflicts with the provisions hereof.  Except as and to the
extent  specifically  set forth in Schedule  5(b) attached  hereto,  neither the
Company nor any of its  subsidiaries  has previously  entered into any agreement
granting any  registration  rights with respect to any of its  securities to any
person or entity. Without limiting the generality of the foregoing,  without the
written  consent  of  the  Investors  of a  majority  of  the  then  outstanding
Registrable  Securities,  the Company shall not grant to any person the right to
request  the  Company  to  register  any  securities  of the  Company  under the
Securities  Act unless the rights so granted are subject in all  respects to the
prior rights in full of the Investors set forth herein, and are not otherwise in
conflict or inconsistent with the provisions of this Agreement.

                  6.  Indemnification.  In the event any Registrable  Securities
are included in a Registration Statement under this Agreement:

                  (a) To the extent permitted by law, the Company will indemnify
and hold  harmless  each  Investor who holds such  Registrable  Securities,  the
directors,  if any, of such  Investor,  the officers,  if any, of such Investor,
each  person,  if any,  who  controls  any  Investor  within the  meaning of the
Securities Act or the Securities Exchange Act of 1934, as amended (the "Exchange
Act")  (each,  an  "Indemnified  Person" or  "Indemnified  Party"),  against any
losses,  claims,  damages,  liabilities or expenses (joint or several)  incurred
(collectively,  "Claims")  to which  any of them may  become  subject  under the
Securities  Act,  the  Exchange  Act or  otherwise,  insofar as such  Claims (or
actions or proceedings,  whether  commenced or threatened,  in respect  thereof)
arise out of or are based upon any of the  following  statements,  omissions  or
violations  in  the  Registration  Statement,  or any  post-effective  amendment
thereof, or any prospectus included therein: (i) any untrue statement or alleged
untrue statement of a material fact contained in the  Registration  Statement or
any  post-effective  amendment  thereof or the  omission or alleged  omission to
state therein a material fact required to be stated therein or necessary to make
the  statements  therein not  misleading,  (ii) any untrue  statement or alleged
untrue  statement  of a material  fact  contained  in the final  prospectus  (as
amended  or  supplemented,  if  the  Company  files  any  amendment  thereof  or
supplement  thereto with the SEC) or the  omission or alleged  omission to state
therein any material fact  necessary to make the  statements  made  therein,  in
light of the  circumstances  under which the  statements  therein were made, not
misleading  or (iii) any  violation  or alleged  violation by the Company of the
Securities  Act,  the  Exchange  Act,  any state  securities  law or any rule or
regulation  under the Securities  Act, the Exchange Act or any state  securities
law (the matters in the foregoing clauses (i) through (iii) 

                                       8
<PAGE>
being, collectively, "Violations"). Subject to clause (b) of this Section 6, the
Company shall  reimburse the  Investors,  promptly as such expenses are incurred
and  are due and  payable,  for any  legal  fees or  other  reasonable  expenses
incurred by them in connection with  investigating  or defending any such Claim.
Notwithstanding  anything to the contrary contained herein, the  indemnification
agreement  contained in this Section 6(a) shall not (I) apply to a Claim arising
out of or based upon a Violation which occurs in reliance upon and in conformity
with  information  furnished  in writing  to the  Company by or on behalf of any
Indemnified  Person  expressly for use in connection with the preparation of the
Registration  Statement or any such amendment thereof or supplement  thereto, if
such  prospectus  was timely made  available by the Company  pursuant to Section
3(c) hereof; (II) be available to the extent such Claim is based on a failure of
the Investor to deliver or cause to be delivered the  prospectus  made available
by the  Company;  or (III) apply to amounts paid in  settlement  of any Claim if
such  settlement is effected  without the prior written  consent of the Company,
which consent shall not be unreasonably  withheld.  Each Investor will indemnify
the Company and its officers,  directors and agents  against any claims  arising
out of or based upon a Violation which occurs in reliance upon and in conformity
with  information  furnished in writing to the Company,  by or on behalf of such
Investor,   expressly  for  use  in  connection  with  the  preparation  of  the
Registration  Statement,  subject  to such  limitations  and  conditions  as are
applicable  to the  Indemnification  provided by the Company to this  Section 6.
Such  indemnity  shall  remain  in  full  force  and  effect  regardless  of any
investigation  made by or on behalf of the Indemnified  Person and shall survive
the transfer of the Registrable  Securities by the Investors pursuant to Section
9.

                  (b)  Promptly  after  receipt  by  an  Indemnified  Person  or
Indemnified  Party  under this  Section 6 of notice of the  commencement  of any
action  (including  any  governmental   action),   such  Indemnified  Person  or
Indemnified Party shall, if a Claim in respect thereof is to be made against any
indemnifying  party under this  Section 6, deliver to the  indemnifying  party a
written notice of the commencement thereof and the indemnifying party shall 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
control  of the  defense  thereof  with  counsel  mutually  satisfactory  to the
indemnifying  party and the Indemnified  Person or the Indemnified Party, as the
case may be. In case any such action is brought against any  Indemnified  Person
or Indemnified Party, and it notifies the indemnifying party of the commencement
thereof,  the indemnifying party will be entitled to participate in, and, to the
extent that it may wish,  jointly with any other  indemnifying  party  similarly
notified,  assume the defense thereof,  subject to the provisions  herein stated
and after  notice  from the  indemnifying  party to such  Indemnified  Person or
Indemnified  Party  of its  election  so to  assume  the  defense  thereof,  the
indemnifying  party will not be liable to such Indemnified Person or Indemnified
Party  under  this  Section  6 for any  reasonable  legal  or  other  reasonable
out-of-pocket  expenses  subsequently  incurred  by such  Indemnified  Person or
Indemnified  Party in connection  with the defense thereof other than reasonable
costs of  investigation,  unless  the  indemnifying  party  shall not pursue the
action of its final  conclusion.  The  Indemnified  Person or Indemnified  Party
shall  have the right to  employ  separate  counsel  in any such  action  and to
participate in the defense  thereof,  but the fees and reasonable  out-of-pocket
expenses of such counsel shall not be at the expense of the  indemnifying  party
if the  indemnifying  party has assumed  the defense of the action with  counsel
reasonably  satisfactory to the  Indemnified  Person or Indemnified  Party.  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 Person or Indemnified Party under this
Section 6, except to the extent that the indemnifying party is prejudiced in its
ability to defend such action.  The  indemnification  required by this Section 6
shall be made by periodic  payments of the 

                                       9
<PAGE>
amount  thereof  during  the course of the  investigation  or  defense,  as such
expense, loss, damage or liability is incurred and is due and payable.

                  7.  Contribution.  To the  extent  any  indemnification  by an
indemnifying  party is  prohibited  or limited by law,  the  indemnifying  party
agrees to make the maximum contribution with respect to any amounts for which it
would  otherwise be liable under  Section 6 to the fullest  extent  permitted by
law;  provided,   however,   that  (a)  no  contribution  shall  be  made  under
circumstances  where the maker  would not have been  liable for  indemnification
under the fault  standards set forth in Section 6; (b) no seller of  Registrable
Securities guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to  contribution  from any seller
of   Registrable   Securities   who  was   not   guilty   of   such   fraudulent
misrepresentation;  and (c) contribution by any seller of Registrable Securities
shall be limited in amount to the net amount of proceeds received by such seller
from the sale of such Registrable Securities.

                  8. Reports under Exchange Act. With a view to making available
to the Investors the benefits of Rule 144  promulgated  under the Securities Act
or any other  similar rule or  regulation of the SEC that may at any time permit
the  Investors  to  sell  securities  of  the  Company  to  the  public  without
registration ("Rule 144"), the Company agrees to:

                  (a)      make and keep public information available,  as those
terms are understood and defined in Rule 144;

                  (b) use its  best  efforts  to file  with  the SEC in a timely

Company that it has complied  with the reporting  requirements  of Rule 144, the

                  9. Assignment of the Registration  Rights.  The rights to have
the Company register Registrable  Securities pursuant to this Agreement shall be
automatically  assigned  by an  Investor to any  transferee  of the  Registrable
Securities (or all or any portion of any Preferred Stock of the Company which is
convertible  into such  securities)  permitted  or allowable by the terms of the
Securities  Purchase Agreement only if: (a) such Investor agrees in writing with
the  transferee or assignee to assign such rights,  and a copy of such agreement
is furnished to the Company within a reasonable time after such assignment,  (b)
the Company is,  within a  reasonable  time after such  transfer or  assignment,
furnished with written notice of (i) the name and address of such  transferee or
assignee and (ii) the securities with respect to which such registration  rights
are being  transferred or assigned,  (c) immediately  following such transfer or
assignment  the further  disposition  of such  securities  by the  transferee or
assignee is restricted  under the Securities Act and applicable state securities
laws,  and (d) at or before the time the Company  received  the  written  notice
contemplated by clause (b) of this sentence the transferee or assignee agrees in
writing  with or in favor of the  Company  to be bound by all of the  provisions
contained  herein, a copy of which shall 

                                       10
<PAGE>
be provided to the Company. The copies referred to in clauses (a) and (d) of the
immediately  preceding  sentence may be redacted to delete certain financial and
other details of the transaction  between the Investor and its transferee if the
same is included in the document to be provided to the Company.  In the event of
any delay in filing or effectiveness  of the Registration  Statement as a result
of such assignment, the Company shall not be liable for any damages arising from
such delay, or the payments set forth in Section 2(c) hereof.

                  10.  Amendment of Registration  Rights.  Any provision of each
such Agreement may be amended and the  observance  thereof may be waived (either
generally   or  in  a   particular   instance   and  either   retroactively   or
prospectively),  only with the written  consent of the Company and Investors who
hold collectively eighty (80%) percent of the Preferred Shares. Any amendment or
waiver  effected in  accordance  with this Section 10 shall be binding upon each
Investor and the Company.

                  11.      Miscellaneous.

                  (a) A person or entity is deemed to be a holder of Registrable
Securities  whenever  such  person or entity  owns of  record  such  Registrable
Securities.  If  the  Company  receives  conflicting  instructions,  notices  or
elections  from  two or more  persons  or  entities  with  respect  to the  same
Registrable  Securities,  the Company shall act upon the basis of  instructions,
notice  or  election  received  from the  registered  owner of such  Registrable
Securities.

                  (d) This  Agreement  shall be governed by and  interpreted  in
accordance  with the laws of the State of California  for contracts to be wholly
performed  in such state and without  giving  effect to the  principles  thereof

to above  and any  claim  that  any such  litigation  has  been  brought  in any
inconvenient  forum. To the extent that the Company has or hereafter may acquire
any immunity from  jurisdiction of any court or from any legal process  (whether
through service or notice,  attachment  prior to judgment,  attachment in aid of
execution  or  otherwise)  with respect to itself or its  property,  the Company
hereby irrevocably waives such immunity in respect of its obligations under this
Agreement and the related agreements entered into in connection herewith.


                  (e) If any  provision  of this  Agreement  shall be invalid or

affect the validity or  enforceability of the remainder of this Agreement or the
validity or enforceability of this Agreement in any other jurisdiction.

                  (f)  Subject to the  requirements  of  Section 9 hereof,  this
Agreement  shall inure to the benefit of and be binding upon the  successors and
assigns of each of the parties hereto.

                  (g) All  pronouns  and any  variations  thereof  refer  to the
masculine, feminine or neuter, singular or plural, as the context may require.

                  (h) The  headings in this  Agreement  are for  convenience  of

<PAGE>
                  (i)  This   Agreement   may  be   executed   in  one  or  more
counterparts,  each of which shall be deemed an original  but all of which shall
constitute one and the same agreement. This Agreement, once executed by a party,
may be  delivered  to  the  other  party  hereto  by  telephone  line  facsimile
transmission  of a copy of this Agreement  bearing the signature of the party so
delivering this Agreement.

                  (j) The Company  acknowledges  that any failure by the Company
to perform its  obligations  under  Section  3(a)  hereof,  or any delay in such
performance could result in loss to the Investors,  and the Company agrees that,
in  addition  to any  other  liability  the  Company  may have by reason of such
failure or delay,  the Company shall be liable for all direct  damages caused by
any such  failure  or delay,  unless  the same is the  result of force  majeure.
Neither party shall be liable for consequential damages.

                  (k) This Agreement,  the Securities Purchase Agreement and the
other documents  referenced  therein  constitute the entire  agreement among the
parties  hereto  with  respect  to  the  subject  matter  hereof.  There  are no
restrictions,  promises, warranties or undertakings,  other than those set forth
or  referred to herein.  This  Agreement  supersedes  all prior  agreements  and
understandings  among the  parties  hereto with  respect to the  subject  matter
hereof. This Agreement may be amended only by an instrument in writing signed by
the party to be charged with enforcement thereof.

                  (l) Any default by an  individual  Investor  hereunder  or any
related  agreement,  including,  without  limitation,  the  Securities  Purchase
Agreement,  shall not be deemed a default  by any other  Investor  and shall not
excuse the Company's  performance  hereunder or  thereunder  with respect to the
non-defaulting Investors.

</TABLE>

THIS  WARRANT  AND THE STOCK  ISSUABLE  UPON THE  EXERCISE  HEREOF HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"),  AND CAN BE
TRANSFERRED  ONLY IN COMPLIANCE  WITH THE ACT AND  APPLICABLE  STATE  SECURITIES
LAWS. THIS WARRANT AND SUCH SECURITIES MAY NOT BE SOLD,  TRANSFERRED OR ASSIGNED
IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT, UNLESS, IN THE OPINION OF
COUNSEL FOR THE COMPANY OR COUNSEL FOR THE REGISTERED  HOLDER (WHICH SHALL BE IN
FORM AND FROM SUCH COUNSEL AS SHALL BE REASONABLY  SATISFACTORY TO THE COMPANY),
SUCH REGISTRATION IS NOT THEN REQUIRED.

                            U.S. WIRELESS DATA, INC.

                          COMMON STOCK PURCHASE WARRANT

         1. Issuance. In consideration of good and valuable  consideration,  the
receipt of which is hereby  acknowledged by U.S. Wireless Data, Inc., a Colorado
corporation  (the  "Company"),  Bold  Street,  LLC,  a  Cayman  Islands  limited
liability  company,  or registered  assigns (the "Holder") is hereby granted the
right to purchase at any time until 5:00 P.M.,  Pacific Coast time, on April 30,
2004 (the "Expiration  Date"),  Three Hundred Thousand  (300,000) fully paid and
nonassessable  shares of the Company's Common Stock, no par value per share (the
"Common  Stock") at an exercise price of $1.50 per share (the "Exercise  Price")
subject to further adjustment as set forth in Section 6 hereof.

                  2. Exercise of Warrants.  This Warrant is exercisable in whole
or in part for whole shares of the Company's  Common Stock at the Exercise Price
per share of Common Stock payable hereunder,  payable in cash or by certified or
official bank check. In lieu of paying cash to exercise this Warrant, the Holder
may, by  designating  a  "cashless"  exercise  on the Notice of  Exercise  Form,
acquire a number of whole shares of the Company's  Common Stock equal to (a) the
difference  between (i) the Market Value of the Company's  Common Stock and (ii)
the  Exercise  Price,  multiplied  by (b) the  number of shares of Common  Stock
purchasable under the portion of the Warrant tendered to the Company, divided by
(c) the Market  Value of the  Company's  Common  Stock.  Upon  surrender of this
Warrant  Certificate  with the annexed  Notice of Exercise  Form duly  executed,
together  with  payment of the  Exercise  Price for the  shares of Common  Stock
purchased, the Holder shall be entitled to receive a certificate or certificates
for the shares of Common Stock so purchased. For the purposes of this Section 2,
"Market  Value" shall be an amount  equal to the average  closing bid price of a
share of Common Stock for the five (5) business days  immediately  preceding the
Company's receipt of the Notice of Exercise Form duly executed.

                  3.  Reservation  of Shares.  The Company hereby agrees that at
all times during the term of this  Warrant  there shall be reserved for issuance
upon exercise of this Warrant such number of shares of its Common Stock as shall
be required for issuance upon exercise of this Warrant (the "Warrant Shares").

                  4. Mutilation or Loss of Warrant.  Upon receipt by the Company
of evidence satisfactory to it of the loss, theft,  destruction or mutilation of
this  Warrant,  and (in the  case of  loss,  theft or  destruction)  receipt  of
reasonably  satisfactory  indemnification,  and (in the case of mutilation) upon
surrender and cancellation of this Warrant, the Company will execute and deliver
a new  Warrant of like tenor and date and any such lost,  stolen,  destroyed  or
mutilated Warrant shall thereupon become void.

<PAGE>
                  5.  Rights of the  Holder.  The Holder  shall  not,  by virtue
hereof, be entitled to any rights of a stockholder in the Company, either at law
or equity,  and the rights of the Holder are limited to those  expressed in this
Warrant and are not  enforceable  against  the Company  except to the extent set
forth herein.

                  6.       Adjustments to Exercise Terms.

                           If  the  Company  at  any  time  prior  to  the  full
execution of this Warrant shall, by subdivision,  combination, merger, spin-off,
re-classification  or like capital  adjustment of the securities,  change any of
the securities to which  purchase  rights under this Warrant exist into the same
or different  number of securities  of any class or classes,  this Warrant shall
thereafter  entitle the Holder to acquire such number and kind of  securities as
would  have  been  issuable  as a result  of such  change  with  respect  to the
securities  acquirable  immediately prior to such transaction.  If shares of the
securities  acquirable  upon  exercise  of this  Warrant are  subdivided  into a
greater  number  of  securities,  including  any  stock  dividend,  or  if  such
securities  are combined into a lesser number of  securities,  then the purchase
price for the  securities  acquirable  upon  exercise  of this  Warrant  and the
securities  acquirable  pursuant to this Warrant  shall be  proportionately  and
equitably adjusted.

                  7. Transfer to Comply with the  Securities  Act;  Registration
Rights.

                  (a) This Warrant has not been registered  under the Securities
Act of 1933,  as  amended,  (the  "Act")  and has been  issued to the Holder for
investment and not with a view to the  distribution of either the Warrant or the
Warrant Shares.  Neither this Warrant nor any of the Warrant Shares or any other
security  issued  or  issuable  upon  exercise  of  this  Warrant  may be  sold,
transferred, pledged or hypothecated in the absence of an effective registration
statement  under the Act and applicable  state  securities laws relating to such
security,  unless in the opinion of counsel  satisfactory  to the Company,  such
registrations  are not required under the Act. Each certificate for the Warrant,
the Warrant  Shares and any other  security  issued or issuable upon exercise of
this Warrant shall  contain a legend on the face thereof,  in form and substance
satisfactory  to counsel for the  Company,  setting  forth the  restrictions  on
transfer contained in this Section.

                  (b) The Company agrees to file a registration statement, which
shall include the Warrant  Shares,  on Form SB-2 or another  available form (the
"Registration  Statement"),  pursuant  to the Act,  pursuant  to a  Registration
Rights Agreement between the Company and Holder dated as of the date hereof (the
"Registration Rights Agreement").

                  8.  Notices.  Any notice or other  communication  required  or
permitted  hereunder  shall be in  writing  and shall be  delivered  personally,
telegraphed,  telexed,  sent by  facsimile  transmission  or sent by  certified,
registered or express mail,  postage  pre-paid.  Any such notice shall be deemed
given when so delivered  personally,  telegraphed,  telexed or sent by facsimile
transmission,  or, if  mailed,  two days after the date of deposit in the United
States mails, as follows:

                                WAIVER OF RIGHTS

                     FIRST AMENDMENT TO DEBENTURE AGREEMENT

     This Waiver of Rights and First Amendment to Debenture Agreement is entered
into  effective as of the 30th day of April 1999,  between U.S.  Wireless  Data,
Inc., a Colorado  corporation  (the "Company") and the undersigned  holders (the
"Holders") of the  Company's 6%  Convertible  Debentures  Due July 21, 2000 (the
"Debentures")  to waive  certain  rights  held by the  Debenture  holders and to
modify and amend the Debenture Agreement relating to the Debentures. RECITALS

          WHEREAS,  the  Company has issued  Debentures  in the  aggregate  face
     amount of $2,000,000;

          WHEREAS,  the  Holders  hold  Debentures  in the face amount set forth
     below its name on the execution page of this Agreement;

          WHEREAS,  the Company owes the undersigned accrued but unpaid interest
     and damages on the  Debentures  through  April 26,  1999 (the  "Calculation
     Date") and has also  agreed to prepay the  balance  of  interest  that will
     become  payable  through June 30, 1999, in the  aggregate  amount set forth
     below each Holder's name on the execution page of this Agreement;

          WHEREAS,  each of the Holders is willing to waive all defaults related
     to the  Debentures  up to the date of this  Agreement,  if the Company pays
     such accrued but unpaid interest and penalties in the form of the Company's
     Series B Cumulative Convertible Redeemable Preferred Stock;

          WHEREAS,  Section III of the Debenture Agreement gives the Holders the
     right to declare the principal and all accrued  interest on such  Debenture
     to be  immediately  due  and  payable  upon  the  satisfaction  of  certain
     conditions;

          WHEREAS,  Section IV.D. of the Debenture  Agreement  gives the Holders
     the  right to  require  the  Company  to  redeem  the  Debentures  upon the
     satisfaction of certain conditions and to receive additional  consideration
     in the event the shares of stock  underlying  the  Debenture are not timely
     registered;

          WHEREAS, the Holders are willing to restrict such rights under Section
     III and Section IV.D. of the Debenture  Agreement in  consideration  of the
     Company  attempting to raise additional capital by selling the Company's 6%
     Series B Cumulative Convertible Redeemable Preferred Stock.

          NOW,  THEREFORE,  in consideration of the Company's  attempts to raise
     additional  capital,   the  opportunity  being  given  to  the  Holders  to
     participate in such offering, and other valuable consideration, the parties
     agrees as follows:

                                                                     Page 1 of 4
<PAGE>
     1. The Holders  agree to  exchange  all  accrued  and unpaid  interest  and
damages due on the  Debentures and all interest that will become payable on such
Debentures on or before June 30, 1999 (such aggregate amount set forth below the
undersigned's  name on the execution  page of this  Agreement) for the Company's
Series B Cumulative Convertible Redeemable Preferred Stock, and to waive any and
all previously  occurring or currently  existing  defaults under the Debentures,
the  Debenture  Agreement,  or any related  registration  rights  agreement.  To
accomplish  the  purchase  of the  Company's  Series  B  Cumulative  Convertible
Redeemable  Preferred  Stock,  the  undersigned  agrees to execute a  Securities
Purchase  Agreement in  substantially  the same form as the  agreement  attached
hereto as Exhibit A.

     2.  Notwithstanding  anything to the contrary in any other  agreement,  the
Debenture  Agreement is hereby  amended so that the Holders waive their right to
declare the principal and all accrued interest on the Debentures immediately due
and payable  pursuant to Section III of the  Debenture  Agreement  solely due to
default in the payment of interest  and the failure to register  the  underlying
shares of Common Stock, prior to the date hereof.

     3. The Holders agree not to declare the  principal and accrued  interest on
the  Debentures  due  and  payable  pursuant  to  Section  III of the  Debenture
Agreement  due to any of the  reasons  set forth in  Section 2 above  unless and
until:

          a.  the  holders  of the  Company's  Series B  Cumulative  Convertible
     Redeemable  Preferred  Stock have a then  exercisable  right of  redemption
     regarding  such stock under  Section  2(b)(iv) of the  Registration  Rights
     Agreement annexed to the Securities  Purchase  Agreement attached hereto as
     Exhibit A (the "New Registration Rights Agreement"); or

          b. 180 days have elapsed following the "Closing Date" (as that term is
     defined in the New Registration Rights Agreement).

     4. Notwithstanding anything to the contrary in any other agreement, Section
IV.D of the Debenture Agreement is hereby amended such that:

          a. the Holders  will not have any right to force the Company to redeem
     any  Debenture  unless  and until the  holders  of the  Company's  Series B
     Cumulative  Convertible  Redeemable Preferred Stock have a then exercisable
     right of redemption  regarding such stock under Section 2(b)(iv) of the New
     Registration Rights Agreement; and

          b. the Holders will have no future right to accrue any penalty for the
     Company's failure to file a registration statement regarding the securities
     underlying the Debentures (the "Registration Statement"),  or the Company's
     failure to cause the Registration Statement to become effective, other than
     as set forth below:

               i. If the Registration Statement is not filed in proper form with
          the  Securities  and  Exchange  Commission  on or before the  Required
          Filing  Date (as that term is 

                                                                     Page 2 of 4
<PAGE>
          defined in the New Registration  Rights  Agreement),  then the Company
          shall pay the undersigned a late filing penalty on the first day after
          such Required  Filing Date in an amount equal to three percent (3%) of
          the face amount of the Debentures then held by the Holders.

               ii. If the  Registration  Statement  is not filed in proper  form
          with the Securities and Exchange  Commission on or before each monthly
          anniversary  of the  Required  Filing Date (as that term is defined in
          the New Registration Rights Agreement), then the Company shall pay the
          Holders a late filing  penalty on each such date in an amount equal to
          three percent (3%) of the face amount of the  Debentures  then held by
          the Holders.

               iii. If the Registration  Statement is not effective on or before
          the  Required  Effective  Date (as  that  term is  defined  in the New
          Registration Rights Agreement), then the Company shall pay the Holders
          a late filing  penalty on the first day after such Required  Effective
          Date in an amount  equal to three  percent  (3%) of the face amount of
          the Debentures then held by the Holders.

               iv. If the  Registration  Statement is not effective on or before
          each monthly  anniversary of the Required Effective Date (as that term
          is defined in the New Registration Rights Agreement), then the Company
          shall pay the  Holders a late  filing  penalty on each such date in an
          amount equal to two percent (2%) of the face amount of the  Debentures
          then held by the Holders.

     5. Except for the remedies  granted to the Holders  pursuant to Section III
and Section IV of the Debenture Agreement,  the Holders do not waive any and all
other remedies  available to them under the Debenture  Agreement and any related
New Registration Rights Agreement.

     6. In all other  respects the Debenture and the Debenture  Agreement  shall
remain unchanged.

     7. This Waiver and  Amendment  Agreement  shall not be binding on any party
until  similar  agreements  are fully  executed by all Holders and the  Company.
Notwithstanding  the  foregoing,  this  Waiver and  Amendment  Agreement  may be
executed in counterparts and by facsimile signature.

     8. This Waiver and Amendment Agreement shall be construed under the laws of
the State of Colorado for contracts  executed and to be performed  fully in such
State.


     IN WITNESS  WHEREOF,  each of the undersigned have executed this Waiver and
Amendment Agreement effective as of the date first above written.

                                                                     Page 3 of 4

                      FORM OF SECURITIES PURCHASE AGREEMENT
                   WITH REGISTRATION RIGHTS AGREEMENT ANNEXED
            
             [Filed herewith as Exhibit 4.1 and 4.2, respectively.]




                        SUPPLEMENT TO SERIES B PREFERRED
                          SECURITIES PURCHASE AGREEMENT


         This Supplement to Series B Preferred Stock Purchase  Agreement is made
and entered into  effective as of the date below,  between U.S.  Wireless  Data,
Inc., a Colorado  corporation (the "Company") and The Cuttyhunk Fund Limited and
Tonga  Partners LP (the  "Purchasers")  in conjunction  with the  acquisition by
Purchasers of shares of the Company's Series B Cumulative Convertible Redeemable
Preferred  Stock (the "Series B  Preferred"),  in exchange  for certain  accrued
interest  and  damages  owing to  Purchasers  on the  Company's  6%  Convertible
Subordinated  Debentures Due July 21, 2000 (the "6%  Debentures")  as more fully
described  in that  certain  Waiver of Rights and First  Amendment  to Debenture
Agreement  dated  as of  the  date  hereof  (the  "Debenture  Amendment").  This
Agreement is entered into to set forth certain additional agreements between the
Company and the Purchasers.

         In  consideration  of the  acquisition of the Series B Preferred by the
Purchasers and the entry of the Debenture  Amendment between the Company and the
Purchasers,  and other good and  valuable  consideration,  the  Company  and the
Purchasers hereby agree as follows:

1.  Notwithstanding  the acquisition of the Series B Preferred by the Purchasers
in exchange for (a) interest  owing on the 6% Debentures  through June 30, 1999,
and (b) damages owing to Purchasers  on the 6%  Debentures,  all as described in
the  Debenture  Amendment,  the  Company  agrees  and  acknowledges  that the 6%
Debentures remain as obligations for money loaned to the Company and will not be
treated as an equity instrument by the Company.

2. The  Company  hereby  acknowledges  and agrees that the  representations  and
warranties of the Company being given to the Purchasers in conjunction  with the
acquisition of the Series B Preferred Stock set forth in the Securities Purchase
Agreement relating thereto,  shall be deemed  representations  and warranties of
the Company  applicable to the 6% Debentures,  made as of the date hereof, as if
the 6%  Debentures  were being  purchased by Purchasers  thereunder.  Purchasers
acknowledge  and affirm  the  representation  and  warranties  contained  in the
Securities  Purchase  Agreement as of the date hereof in  connection  with their
decision to retain their 6% Debentures.

3. The Company agrees that at the time of filing a registration  statement under
the Securities Act of 1933 which includes the shares of Common Stock  underlying
the 6% Debentures  and the Common Stock Purchase  Warrants  issued to Purchasers
with the 6% Debentures  (which shall be the same  registration  statement  which
includes the shares of Common Stock  underlying  the Series B Preferred  Stock),
such  registration  statement  shall  include  for  purposes of  satisfying  the
conversion rights of the 6% Debentures, at least that number of shares of Common
Stock equal to 150% of the number of shares  issuable upon  conversion of the 6%
Debentures as of the last trading date immediately  preceding the date of filing
such registration  statement  together with the number of shares of Common Stock
issuable upon exercise of such Warrants.

Securities Purchase Agreement

4.  The  Company  agrees  that it will  take no  position  inconsistent  with an
original acquisition date of the 6% Debentures by Purchasers of July 23, 1998 in
calculating  the  commencement  of  Purchasers'   holding  periods  for  the  6%
Debentures under Rule 144 of the SEC's Rules and Regulation under the Securities
Act of 1933.

5. The Company  acknowledges  that  Purchasers have advised it that they are not
affiliated  in any  manner  with the other  initial  Purchaser  of the  Series B
Preferred,  Bold Street LLC, a Cayman limited liability company, and the Company
acknowledges that it is not aware of any facts contrary to this assertion.

6. Notwithstanding Section 4.j in the Securities Purchase Agreement,  Purchasers
acknowledge that they are not entitled to any warrants in conjunction with their
acquisition of Series B Preferred in exchange for the interest and damages owing
on the 6% Debentures.

7. The Company hereby agrees that the 6% Debentures currently held by Purchasers
shall be  amended  such that  Purchasers  shall  have the  benefit  of any terms
contained  in  the  Securities  Purchase  Agreement,   the  Registration  Rights
Agreement or Certificate of Designation  for the Series B Preferred.  Purchasers
shall reasonably determine which terms they deem beneficial.  Any such amendment
shall be subject to the review of the  Company's  independent  accountants,  and
should such accountants  determine that any such amendment(s)  determined by the
Purchasers  (or  the  right  granted  hereby  to  Purchasers  to  determine  the
applicability of such amendment(s))  would require a reclassification  of the 6%
Debentures  into  other  than a debt  instrument  of the  Company,  then no such
amendment  shall be permitted and this clause shall be considered void ab-initio
as to any such right to amend the 6% Debentures or the rights related thereto.

8. The Company  agrees that it will pay the legal fees incurred by Purchasers in
connection with the  negotiation of the Debenture  Amendment and the acquisition
of the Series B Preferred,  in an amount of $9,775, to be paid from the proceeds
of the sale of the Series B Preferred, immediately following the initial closing
of the sale of the Series B Preferred  and  presentation  of an invoice from The
Goldstein  Law  Group,   P.C.,   which  has  represented   Purchasers  in  these
transactions.

                                 FIRST AMENDMENT
                                       TO
                    NOTE AND COMMON STOCK PURCHASE AGREEMENT

         This First  Amendment  to Note and Common Stock  Purchase  Agreement is
entered into  effective as of the 22nd day of April 1999,  to amend the Note and
Common Stock Purchase  Agreement (the  "Agreement")  between U.S. Wireless Data,
Inc., a Colorado  corporation  (the "Company") and the  undersigned  ("Holder"),
pursuant to which Holder  holds the  Company's  $250,000  Note due June 12, 1999
(the "Note").

                                    RECITALS

         WHEREAS,  Section 4 of the Agreement  requires that the Note be paid in
full at the time the company sells any equity or debt securities of the Company,
provided the Company has received  gross  proceeds in the minimum amount of U.S.
one million dollars (US$1,000,000);

         WHEREAS, Holder is willing to amend Section 4 of the Agreement to allow
the Company to delay prepayment of the Note;

         NOW,  THEREFORE,  in consideration  of the Company's  attempts to raise
additional  capital,  and the  opportunity  being  given to the  undersigned  to
participate in that offering, Holder and Company agree as follows:

1.       Section 4 of the Agreement is amended to read as follows:

     4. Prepayment of the Note.  Investor  understands that the Company has been
     engaged in discussions with various parties, including Investor,  regarding
     the  possible  issuance  by  the  Company  of  additional  debt  or  equity
     securities (apart from the Bridge Financing described above), including the
     possible  issuance of a Preferred  Stock to be authorized and issued by the
     Company upon final agreement as to the terms of such Preferred  Stock.  The
     Company  and  Investor  agree that at any time prior to the Due Date of the
     Note, the Note shall be paid in full (as to all amounts of unpaid principal
     and  interest  then owing)  from the  proceeds of the sale of any equity or
     debt  securities  of the Company  (including  shares of  Preferred  Stock),
     provided the Company has received  gross  proceeds in the minimum amount of
     U.S. Two Million Five Hundred Thousand Dollars (US$2,500,000) from the sale
     of such equity or debt  securities (but from which amount any proceeds from
     a  Bridge  Financing  or  conversion  of  previously   existing  debentures
     (including interest and penalties on such debentures) shall be excluded).

2. Holder will forebear from initiating an action against the Company to collect
the  obligation  evidenced  by the  Note  until  (a)  prepayment  of the Note is
required  pursuant  to  Section 4 of the  Agreement,  or (b)  December  1, 1999,
whichever is first to occur. Notwithstanding the foregoing, Holder preserves its
right  to  collect  the  obligation  evidenced  by  the  Note  from  any  person
guarantying the Note.

3. In all other respects the Agreement shall remain unchanged.


                            First Amendment to Note and Stock Purchase Agreement
                                                                     Page 1 of 2
<PAGE>
         IN WITNESS WHEREOF,  the undersigned have executed this First Amendment
to Debenture Agreement effective as of the date first above written.

FOR IMMEDIATE RELEASE
- ---------------------

U.S. Wireless Data Announces Equity Financing

EMERYVILLE,  CA - (May 7, 1999) - U.S.  WIRELESS  DATA,  INC.  ("USWD")  (OTCBB:
USWDA)  announced  today  it has  completed  the  first  phase of a $1.5 to $5.0
million  private  placement  pursuant to Regulation D of the  Securities  Act of
1933. The financing was facilitated by an institutional investor,  through which
the  Company  raised  gross  proceeds  of  $1,500,000.  The  Company  issued  6%
Cumulative  Convertible  Redeemable  Preferred  Stock  (Series  B) for $1.00 per
share.  The instrument gives the holder the right to convert the Preferred Stock
into shares of the  Company's  Common Stock in the future at 80% of then current
market price. Concurrent with this transaction,  the holders of the Company's 6%
Convertible Debentures agreed to convert all accrued interest and penalties into
shares of the Series B Preferred  Stock. The Series B Preferred Stock and Common
Stock to be issued upon conversion  have not been  registered  under the Act and
may not be  offered  or sold in the  United  States  absent  registration  or an
applicable  exemption from  registration  requirements.  The Company will file a
Current Report on Form 8-K with the Securities and Exchange  Commission  setting
forth further details with respect to the financing  including  conversion terms
and registration rights.

Forward-Looking  Statements:  Certain information above contains forward-looking
statements  that involve risk and  uncertainties.  While the  management  of the
Company believes that current  expectations reflect reasonable  assumptions,  no
assurances  can be given that the Company will  achieve its goals.  Factors that
could cause actual results to differ materially include, but are not limited to:
the Company's  requirement  for  additional  capital;  failure of the Company to
raise additional capital critical to continue ongoing operations, the failure to
execute  definitive  agreements  with  potential  strategic  alliance  partners;
technological  change;  the ability of the  Company to develop new  distribution
channels;  or the  intensification  of  competition.  The  reports  filed by the
Company pursuant to United States securities laws contain a detailed  discussion
of these  factors  and  certain  other  risks to which the  Company is  subject.
Management of the Company  advises the reader to review these reports (which are
available  from the United States  Securities  and Exchange  Commission's  EDGAR
database  at  http://www.sec.gov  and  at  various  other  Commission  reference
facilities in the United States) before making an investment  decision regarding
the Company or its securities.
