Closing of Private Offering of 8% Adjustable Rate
Convertible Subordinated Debentures Due December 31, 1999
- ---------------------------------------------------------

         On December 10, 1997, U.S. Wireless Data, Inc. (the "Company") closed a
private   offering  of  $3,060,000   principal  amount  of  8%  Adjustable  Rate
Convertible  Subordinated  Debentures due December 31, 1999 (the  "Debentures").
The net  proceeds to the Company  from the offering  will be  $2,769,300,  after
paying finder's  commissions of $290,700,  but before paying additional expenses
of the  offering,  which are  estimated  at $50,000.  The  Company  will use the
proceeds  from the offering  primarily  as working  capital to fund the national
launch of its  proprietary  wireless  transactions  processing  solutions and to
repay existing obligations.

         The  following  is a summary  of the terms and  conditions  of  certain
agreements  entered  into or to be entered  into  between  the  Company  and the
purchasers of the  Debentures.  The  descriptions of the terms of the agreements
are  qualified  in their  entirety  by  reference  to  copies  of the  operative
documents,  including the Debenture Agreement (and form of Debenture Certificate
included  therein),  proposed  form of Articles of  Amendment  to the  Company's
Articles  of  Incorporation   (including  Designation  of  Series  A  Cumulative
Convertible  Redeemable  Preferred Stock), the Registration Rights Agreement and
the form of Subscription Agreement, which are filed as Exhibits to this Report.

         The Debentures will  automatically  convert into shares of no par value
Series A Cumulative  Convertible Redeemable Preferred Stock, with a stated value
of $1.00 per share (the "Preferred Stock") at any time prior to maturity, unless
previously  redeemed  or  converted  into shares of the  Company's  no par value
common stock (the "Common  Stock"),  upon  effectiveness  of an amendment to the
Company's  Articles  of  Incorporation  authorizing  the  Company  to issue  the
Preferred  Stock.  The  conversion  rate will be equal to one share of Preferred
Stock  for  each  dollar  of  principal  face  amount  of the  Debentures  being
converted.  Any accrued but unpaid  interest owing on the Debentures to the date
of conversion will be paid either in cash or in Common Stock of the Company.  No
fractional shares of Preferred Stock will be issued upon conversion.

         The  Debentures  or the shares of Preferred  Stock into which they have
been  converted  will be further  convertible  at the option of the holder  into
shares of Common Stock effective upon (a) an amendment to the Company's Articles
of Incorporation  increasing the number of shares of authorized Common Stock and
(b) the earlier of (i) a declaration  of  effectiveness  by the  Securities  and
Exchange Commission (the "SEC") of a registration  statement covering the shares
of Common Stock into which the  Debentures  or Preferred  Stock are  convertible
(the "Common Stock  Registration  Statement") or (ii) 150 days from December 10,
1997.  The rate at which the  Debentures  or  Preferred  Stock  are  convertible
(either per dollar of  Debenture or per share of  Preferred  Stock,  into Common
Stock (the "Conversion  Price") is equal to the lesser of (i) $6.00 per share of
Common  Stock or (ii) 80% of the  average of the closing bid price of the Common
Stock over the five trading days prior to conversion. The Conversion Price is no
less than $4.00 per share of Common  Stock for 270 days from  December  10, 1997
(the  "Minimum  Conversion  Price").  After  that 270 day  period,  the  Minimum
Conversion Price no longer applicable. No fractional shares of Common Stock will
be issued upon  conversion of Debentures or shares of Preferred  Stock;  rather,
the Company will either pay cash for such  fractional  share or apply a rounding
formula to issue only full shares of Common Stock.

         The Debentures (or the Preferred  Stock into which the Debentures  have
become converted)  automatically convert to Common Stock (if a sufficient number
of shares are available) if the Company closes a $5,000,000 public offering at a
minimum  share  price of  $10.00.  The  shares of Common  Stock  into  which the
Debentures  and/or the Preferred Stock are convertible and which are issuable as
interest on the  Debentures  and dividends on the Preferred  Stock are hereafter
referred to as the "D/PS Common Stock."

                                       -2-
<PAGE>
         Interest on the Debentures  (or  cumulative  dividends on the Preferred
Stock  which  become  payable  once the  Debentures  have  become  converted  to
Preferred  Stock)  are  payable  in arrears to holders of record as of March 31,
June 30, September 30 and December 31 of each year, beginning December 31, 1997,
at an initial  rate of 8% per annum,  subject to  reduction to 4% per annum upon
effectiveness  of a registration  statement under the Securities Act of 1933, as
amended (the "1933 Act") covering the Common Stock  issuable upon  conversion of
the  Debentures (or the Preferred  Stock into which the  Debentures  have become
converted)  (the "Common Stock  Registration  Statement").  Unless  converted or
redeemed,  the Debentures  will be due and payable in full on December 31, 1999.
Interest  on  the  Debentures  (or  dividends  on  the  Preferred  Stock  if the
Debentures have become converted to Preferred Stock) is payable in Common Stock,
if possible.

         The Company  does not  presently  have an adequate  number of shares of
Common  Stock  authorized  to allow  payment of interest on the  Debentures  (or
dividends  on the  Preferred  Stock) to be paid in shares of Common  Stock or to
allow for conversion of the Debentures or Preferred  Stock into shares of Common
Stock, nor does the Company have shares of Preferred Stock presently authorized.
The  Company  has taken  steps to hold an Annual  Meeting  of  Shareholders  and
intends to promptly file a proxy  statement with the SEC to solicit  proxies for
that meeting at which  proposals will be submitted to  shareholders to amend the
Company's Articles of Incorporation to authorize a total of 15,000,000 shares of
no par value "blank  check"  preferred  stock  (4,000,000 of which would then be
designated by the Board of Directors as the Series A Preferred  Stock into which
the Debentures would then  automatically  become  converted) and to increase the
number of shares of Common Stock from its present number of 12,000,000 shares to
40,000,000 shares. The Company hopes to hold its Annual meeting by no later than
January 30, 1998,  based on a December 15, 1997 record date. If approval for the
increases in authorized  capital is not obtained,  interest or dividends will be
payable  in cash and the  Debentures  will  remain  as  unsecured,  subordinated
interest-bearing obligations of the Company, payable in cash.

         The  number of shares of Common  Stock  issuable  at each  interest  or
dividend  payment date will be  determined by applying the  applicable  interest
rate to determine  the dollar amount of the payment due,  then  converting  that
amount to the  appropriate  number of shares  based on the  average  closing bid
price of the Common Stock over the last five  trading  days of the  quarter,  as
quoted on the OTC Electronic Bulletin Board or the price as quoted on The Nasdaq
Stock  Market or another  exchange,  if and when the stock is listed on any such
exchange.  No  fractional  shares of Common  Stock will be issued as interest or
dividends;  rather,  a Holder entitled to a fractional share will receive at the
Company's  option,  either a cash payment for such fractional  share or the next
higher or lower number of whole shares, as calculated using a rounding formula.

         The Company also entered into an agreement  with the  purchasers of the
Debentures  to file a  registration  statement  with the SEC  covering  the D/PS
Common Stock within 90 days of December 10, 1997.  The Company will use its best
efforts to obtain effectiveness of the registration  statement.  However, if the
Company is unable to do so within 150 days of December 10, 1997,  the Conversion
Price (or Minimum Conversion Price, if then in effect) for the Debentures and/or
Preferred Stock will be discounted by 2% off the then-existing  conversion price
for each thirty day period (or  fraction of any thirty day period)  during which
the  registration  statement  is not  effective  after  such  150th day and such
discount  will apply  thereafter to determine  the  Conversion  Price or Minimum
Conversion  Price  applicable to the  Debentures  and/or  Preferred  Stock.  The
Company is to use its best efforts to maintain effectiveness of the registration
statement  for 16 months from June 30,  1998.  The  Company  will be required to
include up to  approximately  6,385,000  additional  shares in the  registration
statement  which are the subject of "piggyback"  registration  rights granted to
other holders of the Company's securities.  A total of 5,100,000 of those shares
are  registrable  for the benefit of  Liviakis  Financial  Communications,  Inc.
("LFC") and two affiliates of LFC, Messrs.  John M. Liviakis and Robert B. Prag.
LFC and Messrs. Liviakis and Prag have agreed that they will not sell any shares
under the registration  (even if they elect to have their shares included in the
registration)  until at least July 31,  1998.  A copy of the  Lock-up  Agreement
dated  November  25, 1997 that was entered  into between the Company and LFC and
Messrs. Liviakis and Prag is filed as an Exhibit to this Report.

                                       -3-
<PAGE>
         The Company may redeem the Debentures and/or the Preferred Stock at any
time  during  the first 270 days  following  the  initial  closing  date of this
offering (and for 60 days thereafter under certain circumstances) if the closing
bid price (or last sale price, if available) of the Common Stock for at least 20
trading days in any  consecutive  30 trading day period is less than the Minimum
Conversion  Price.  The  Company  must pay  118% of the  holder's  initial  cash
investment to redeem either  Debentures or Preferred Stock, plus pay accrued but
unpaid  dividends  to the date of  redemption.  The  Company may also redeem any
Preferred Stock  outstanding three years from December 10, 1997, at stated value
plus accrued and unpaid dividends.

         The Company has agreed with the  purchasers of the  Debentures  that it
will not offer any  equity  securities  in  private  offerings  pursuant  to SEC
Regulations D or S or otherwise, for 150 days from December 10, 1997. After such
period,  and  continuing  until the  shares  underlying  the  Debentures  and/or
Preferred  Stock have been registered for public sale, the Company has granted a
first right of refusal to the  purchasers  of the  Debentures  to  purchase  any
equity securities offered privately by the Company pursuant to SEC Regulations D
or S or otherwise.

         The offering was made  pursuant to Rule 506 of Regulation D and Section
4(2) of the 1933 Act. The  Debentures,  the Preferred  Stock and the D/PS Common
Stock (hereafter  collectively referred to as the "Securities") are, or will be,
when issued,  "restricted securities" as defined under Rule 144 of the 1933 Act.
Holders  will  not  be  able  to  resell  the  Securities  absent  an  effective
registration  statement  covering  the  Securities  or an  exemption  from  such
registration requirements, the availability of which must be demonstrated to the
satisfaction  of the  Company.  There is  currently  no  public  market  for the
Debentures  or the  Preferred  Stock and there is no  intention  that any public
trading market develop for the Debentures or Preferred Stock.

         JW Charles Securities, Inc. of Boca Raton, Florida, acted as finder for
the Company in connection with the offering.  JW Charles received a finder's fee
of 7% of the gross offering  proceeds and a Stock  Purchase  Warrant to purchase
50,000  shares of the  Company's  Common Stock at $6.525 per share,  exercisable
until December 10, 2000. The shares  underlying the Warrant have both demand and
"piggyback" registration rights. The Company is also obligated to pay a finder's
fee of 2.5% of the gross offering  proceeds,  or $76,500,  to Liviakis Financial
Communications,  Inc. for its assistance in locating JW Charles  Securities.  In
addition to the  finder's  fee,  the Company will repay bridge loans from LFC in
the amount of $475,000 using proceeds from this offering.

         In order to facilitate the offering, additional agreements were entered
into with the Company and certain persons,  as follows. As of November 11, 1997,
all officers,  directors and greater than 5%  shareholders of the Company signed
voting  agreements  by which they agreed to vote all shares  owned by them as of
the record  date of the  Company's  Annual  meeting in favor of the  increase in
Common Stock from  12,000,000  to  40,000,000  shares and the  authorization  of
15,000,000  shares  of  preferred  stock,  up to  4,000,000  of which  are to be
designated  as  Series  A  Preferred  Stock.  A copy of the  Shareholder  Voting
Agreement is filed as an Exhibit to this Report. In addition,  Messrs.  Liviakis
and Prag agreed as of October 20, 1997, to refrain from exercising the 1,600,000
warrants  they own until the later of January 15,  1998 or the time  immediately
following the next Annual Meeting of  Shareholders  of the Company.  The Company
agreed that it would  submit the  increase  in  authorized  Common  Stock to its
shareholders at that meeting. A copy of the Letter Agreement between the Company
and Messrs.  Liviakis and Prag dated  October 20, 1997 is filed as an Exhibit to
this Report.

Demands by Certain Noteholders

         During April - June,  1997,  the Company  issued a total of $185,000 of
Demand  Notes  payable in full on or before  April 11, 1998 (the  "Notes").  The
principal and accrued  interest on the Notes became  convertible  into shares of
the  Company's  Common  Stock as of November 1, 1997 at prices of $.35 per share
(as to $75,000

                                       -4-
<PAGE>
of the Notes) and $.50 per share (as to $110,000 of the  Notes).  Commencing  on
November 3, 1997,  the  Company  began  receiving  conversion  demands  from the
Noteholders  and as of November 14,  1997,  holders of $135,000 of the Notes had
demanded  conversion of their Notes into Common Stock and are insisting that the
Company issue  "free-trading"  shares to them. The Noteholders  claim that their
right to free-trading stock arises out of certain oral  representations  made at
the time of  issuance  of the Notes,  the fact that no  "restricted  securities"
legends  were  imprinted  on the  documents  comprising  the  Notes and no other
written advice as to the "restricted"  nature of the shares underlying the Notes
was given to them at the time. The Company believes the Noteholders'  claims are
without merit for at least the following  reasons:  (1) no  registration  rights
were granted to the  Noteholders  regarding the shares  underlying the Notes and
(2) the Company  cannot  issue  free-trading  stock  without  going  through SEC
registration  and never  actually  authorized  (nor would have  authorized)  any
person  to  make  oral  representations  granting  registration  rights  to  the
Noteholders.  No assurance can be given that the matter can be resolved  without
litigation.  The  shares  into  which  the Notes are  convertible  would  become
saleable  under SEC Rule 144 in the  Spring of 1998,  one year from the dates on
which the Notes were issued.

THE DEBENTURES HAVE NOT BEEN REGISTERED  UNDER THE SECURITIES ACT OF 1933 OR ANY

                                    8% ADJUSTABLE RATE CONVERTIBLE SUBORDINATED
                                         DEBENTURES DUE DECEMBER 31, 1999

         This  Debenture  Agreement is entered into between U. S. Wireless Data,
Inc.,  a  Colorado   corporation  (the  "Corporation")  and  purchasers  of  the
Corporation's  8%  Adjustable  Rate  Convertible   Subordinated  Debentures  Due
December 31, 1999 (the  "Debentures").  The Debentures are due in one payment of
principal and any and all accrued but unpaid  interest then due, on December 31,
1999 (the  "Maturity  Date"),  unless  earlier  converted  pursuant to the terms
hereof.  Interest  shall accrue on the  Debentures  at the initial rate of eight
percent  (8%) per annum,  subject to  adjustment  of such rate as  provided  for
herein,  the primary rate of interest in effect at any time being referred to as
the "Applicable Interest Rate."

         The  Debentures  shall be evidenced by Debenture  Certificates  annexed
hereto  as  Exhibit  1,  which  shall be valid  only  when  countersigned  by an
authorized representative of the Corporation.

         The  Debentures  are issued as part of a series of 8%  Adjustable  Rate
Convertible  Subordinated  Debentures  privately  issued by the  Corporation and
known  as the "8%  Adjustable  Rate  Convertible  Subordinated  Debentures,  Due
December 31, 1999," each of which has been or will be issued to a Holder who has
or  will  represent  to the  Corporation  that  he,  she or it is an  accredited
investor,  as that term is defined in Rule 501(a) of the Securities Act of 1933,
as amended (the "1933 Act").  The Holder of a Debenture  hereby  reaffirms  such
representation  to the  Corporation  and each other  Holder of  Debentures.  The
minimum  principal dollar amount of the Debentures is $2,000,000 and the maximum
principal amount may be up to $4,000,000.

     Any  principal or interest on any  Debenture  which is payable,  but is not
punctually  paid or  duly  provided  for at the  Maturity  Date or any  Interest
Payment  Record Date (herein  called  "Default  Interest")  shall bear  compound
interest at a rate of two percent (2%) over the  Applicable  Interest  Rate from
the date of default until paid.

I.       Interest Payments and Adjustment of Interest Rate.
         --------------------------------------------------

         A. The  Debentures  shall  accrue  interest  from the date of  original
issuance by the Corporation at the initial rate of eight percent (8%) per annum,
based on a 360 day year and 90 day quarters.  The interest rate shall be reduced
to four  percent  (4%) per annum upon initial  effectiveness  of a  registration
statement with the United State  Securities and Exchange  Commission (the "SEC")
covering the shares of Common Stock into which the  Debentures (or the Preferred
Stock into which the Debentures will automatically convert upon authorization of
such Preferred Stock by the  Corporation)  are convertible and shall continue at
such rate until maturity, unless Default Interest becomes applicable.

         B. Interest shall be payable quarterly to Debentureholders of record as
of March 31, June 31,  September 30 and December 31 of each year (the  "Interest
Payment Record Dates"),  commencing December 31, 1997. The payment date for each
interest  payment  shall be on or before  the 15th of the month  following  each
Interest Payment Record Date, or the next Business Day thereafter if such day is
not a Business Day.

         C.  Interest  on the  Debentures  shall be  payable  in  shares  of the
Corporation's  Common Stock,  provided the Corporation has an adequate number of
authorized shares of Common Stock from which to make interest payments. Interest
payments may be paid in  authorized  and  unissued  shares of Common Stock or in
shares of Common  Stock in the  treasury of the  Corporation.  As of the date of
initial  issuance of the Debentures,  the  Corporation has 12,000,000  shares of
Common Stock  authorized and does not have an adequate  number of authorized and
unissued  shares of Common Stock or treasury  shares of Common  Stock  available
from which to make interest  payments on the Debentures.  The Corporation  shall
submit an amendment to its Articles of Incorporation to shareholders at its next
Annual  Meeting of  Shareholders  (tentatively  scheduled for December 17, 1997)
pursuant to which it shall  request an increase in  authorized  Common  Stock to
40,000,000 shares (the "Increase Amendment"). The Corporation shall use its best
efforts to secure approval for the Increase Amendment by shareholders. Following
approval of the  Increase  Amendment  by  shareholders,  the  Corporation  shall
continuously  maintain a sufficient  number of authorized and unissued shares of
Common Stock to allow  interest on the Debentures to be paid in shares of Common
Stock.  Unless  and until  the  Corporation  obtains  approval  of the  Increase
Amendment by shareholders, interest on the Debentures shall be payable in cash.

         D. If the Corporation  pays interest in shares of its Common Stock, the
number of shares of Common Stock  issuable at each Interest  Payment Record Date
shall be calculated as follows:  The amount of the interest payment owing on the
Debenture at the Interest  Payment  Record Date (in dollars) shall be divided by
the  average  closing bid price of the Common  Stock over the last five  trading
days prior to the Interest  Payment  Record Date as quoted on the OTC Electronic
Bulletin Board or such other quotation service as is quoting


                                       -2-
<PAGE>
bid and asked prices for the Common Stock. If the Common Stock is then listed on
the NASDAQ Stock Market or any other national exchange,  the five day average of
the closing  bid price for the Common  Stock for such days as reported on NASDAQ
or such other national securities exchange shall be substituted for the five day
average  closing bid price as reported by the OTC  Electronic  Bulletin Board or
other  quotation  service.  In the event the  Common  Stock is not quoted on any
exchange  or  quotation  service,  then the Board of  Directors,  acting in good
faith,  shall  adopt a  resolution  valuing  the Common  Stock for  purposes  of
determining  the number of shares of Common  Stock  issuable  as interest on the
Debentures at each Interest Payment Record Date. Absent fraud, the determination
of the Board of  Directors  shall be binding  and  conclusive.  The value of the
Common Stock used for purposes of determining  the number of shares  issuable as
interest on the  Debentures or for purposes of  conversion  of  Debentures  into
Common  Stock  pursuant to Sections IV and/or V of this  Debenture  Agreement is
hereafter  referred to as the "Market Price." When computed in connection with a
conversion  transaction,  the average  shall be computed  using the five trading
days prior to the Common Stock Conversion Date.

         E. The  Corporation  shall use its best efforts to maintain the listing
of the Common Stock on the OTC Electronic Bulletin Board or such other quotation
service or exchange  on which the Common  Stock may be listed for  trading,  and
shall not take any action at any time while  Debentures  are  Outstanding  which
would result in the delisting of the Common Stock from any quotation  service or
exchange  upon which the Common Stock may be so listed.  The  Corporation  shall
file  all  reports  required  to be filed  by it with  the SEC  pursuant  to the
Securities  Exchange  Act of 1934 (the "1934 Act") and/or the 1933 Act and shall
not take any action which would result in the deregistration of the Common Stock
under Section 12(g) of the 1934 Act.

         F. No  fractional  shares of Common Stock will be issued as interest on
the Debentures;  rather, a  Debentureholder  otherwise  entitled to a fractional
share may  receive,  at the sole option of the  Corporation,  either (i) cash in
lieu of such fractional share, or (ii) the next higher whole number of shares of
Common Stock if the fractional share to which the  Debentureholder  is otherwise
entitled is equal to 0.5 or greater, or the next lower whole number of shares of
Common Stock if the fractional share to which the  Debentureholder  is otherwise
entitled is less than 0.5.

         G. The  Corporation  shall  provide  Debentureholders  with a statement
showing the manner in which it calculated the interest  payable at each Interest
Payment  Record Date,  including  the  calculation  used to determine the Market
Price  and the  number  of shares of  Common  Stock  issued as  interest  on the
Debenture.

         H.  Principal  and  interest on the  Debentures  will be  payable,  and
transfer of the Debentures  will be  registrable at the Principal  Office of the
Corporation.  Upon the request of the Debentureholder,  payment of principal and
interest  shall be made by delivery of a check and/or Common Stock  certificates
(as applicable)  representing  interest to the registered  holder mailed to such
holder's address as it appears on the Debenture register.


                                       -3-
<PAGE>
         I.  Notwithstanding  the number of Debenture  certificates which may be
issued  to a  single  Debentureholder,  the  Corporation  shall be  entitled  to
aggregate  the  principal  amounts  of all  Debentures  held by such  Holder for
purposes of calculating interest payable to such Holder.

II.  Events of  Default.  The  following  shall  constitute  Events  of  Default
     -------------------  hereunder:

     A. Default in the payment of any interest or principal  upon any  Debenture
when the same becomes due and  payable,  and  continuance  of such default for a
period of 30 days; or

     B. Default in the performance, or breach, of any other covenant or warranty
of the Corporation in the Debentures,  and continuance of such default or breach
for a period of 60 days after notice of such breach or default has been given by
any Debentureholder by registered or certified mail, to the Corporation; or

     C. The entry of a decree  or order by a court  having  proper  jurisdiction
adjudging  the  Corporation  a bankrupt or  insolvent,  or approving as properly
filed a petition seeking reorganization,  arrangement, adjustment or composition
of or in  respect  of the  Corporation  under the  Bankruptcy  Code or any other
applicable Federal or state law, or appointing a receiver, liquidator, assignee,
custodian,  trustee,  sequestrator  (or other  similar  official)  (hereafter  a
"Trustee") for the Corporation or for any substantial  part of its property,  or
ordering the winding up or  liquidation of its affairs,  and the  continuance of
any such decree or order  unstayed and in effect for a period of 60  consecutive
days; or

     D. The  institution  by the  Corporation of proceedings to be adjudicated a
bankrupt or insolvent,  or the consent by it to the institution of bankruptcy or
insolvency  proceedings  against it, or the filing by it of a petition or answer
or consent  seeking  reorganization  or relief under the Bankruptcy  Code or any
other applicable Federal or state law, or the consent by it to the filing of any
such  petition  or to  the  appointment  of a  receiver,  liquidator,  assignee,
custodian,  trustee, sequestrator (or other similar official) of the Corporation
or of any substantial part of its property, or the making by it of an assignment
for the benefit of creditors, or the admission by it in writing of its inability
to pay its debts generally as they become due, or the taking of corporate action
by the Corporation in furtherance of any such action.

III.     Acceleration.
         -------------

         Within 45 days after the occurrence of any Event of Default  hereunder,
the  Corporation  shall mail  notice of such  default  to all  Debentureholders,
unless such default shall have been cured or waived.

         If an Event of Default occurs and is continuing, then the Holder of any
Debenture then Outstanding may declare the principal and all accrued interest on
such Debenture to be


                                       -4-
<PAGE>
immediately due and payable, by a notice in writing to the Corporation, and upon
any such declaration such principal shall become immediately due and payable.

         At any time after such a declaration of acceleration  has been made and
before a judgment  or decree for  payment  of money due has been  obtained,  the
Holder  declaring such default may, by written notice to the Corporation and any
trustee  appointed for the  Corporation,  may rescind and annul such declaration
and its  consequences if the Corporation has paid or deposited with such trustee
a sum  sufficient  to pay all  principal  and accrued  interest,  including  any
Default Interest, on the Debentures.

IV.      Automatic Conversion of Debentures.
         -----------------------------------

         A.  Into  Shares of  Series A  Preferred  Stock.  This  Debenture  will
automatically  convert into one share of the Corporation's no par value Series A
Cumulative  Convertible Redeemable Preferred Stock, stated value $1.00 per share
(the  "Preferred  Stock")  for each  $1.00 of  Debentures,  at any time prior to
maturity,  unless  previously  redeemed or  converted  into Common  Stock,  upon
effectiveness  of an amendment to the  Corporation's  Articles of  Incorporation
authorizing the  Corporation to issue the Preferred Stock (the "Preferred  Stock
Amendment").   The  Preferred   Stock   Amendment   will  be  submitted  to  the
Corporation's  shareholders at the next Annual Shareholder Meeting  (tentatively
scheduled for December 17, 1997).  The Corporation  will use its best efforts to
obtain  approval for the Preferred  Stock  Amendment.  Debentureholders  will be
notified  as soon as  practicable  upon  effectiveness  of the  Preferred  Stock
Amendment.

         B. Into  Shares of Common  Stock.  The  Debentures  will  automatically
convert  into  fully  paid and  non-assessable  shares  of  Common  Stock of the
Corporation,  at the  then  applicable  Conversion  Price  (as  defined  below),
immediately  prior  to the  closing  of a firm  commitment  underwritten  public
offering  of the  shares  of  Common  Stock  of the  Corporation  pursuant  to a
registration  statement  filed under the 1933 Act at an offering price per share
of  not  less  than  ten  dollars  ($10.00)  per  share  (prior  to  underwriter
commissions  and  expenses  and  adjusted  for stock  splits,  stock  dividends,
reorganizations  and the like) and with aggregate gross offering proceeds to the
Corporation  of not less than Five Million  Dollars  ($5,000,000)  (a "Qualified
Public Offering").

         C. Any accrued but unpaid  interest owing on the Debentures to the date
of  conversion  will be payable by the  Corporation  as  described  in Article I
above,  either  in cash or  shares of  Common  Stock.  In the case of  automatic
conversion into Preferred Stock, accrued interest to the date of conversion will
be carried over and paid on the next  dividend  payment date  applicable  to the
Preferred Stock into which the Debentures  have been  converted.  In the case of
automatic  conversion  into  Common  Stock,  accrued  interest  to the  date  of
conversion  will be paid at the same  time as the  Common  Stock  issuable  upon
conversion of the Debenture is delivered to the Holder.



                                       -5-
<PAGE>
         D. The  Corporation  shall  provide  notice to the  Holders  as soon as
practicable  after  the  date  of  the  effectiveness  of  the  Preferred  Stock
Amendment.  The  Corporation  shall provide  notice to the Holders as soon as is
practicable  of the time when the  Corporation  will  close a  Qualified  Public
Offering.  At  the  same  time  that  it  notifies  the  Debentureholder  of the
effectiveness  of the  Preferred  Stock  Amendment  or the  closing  date  for a
Qualified  Public  Offering,  the  Corporation  shall  include  a notice  to the
Debentureholder  of the amount of interest  accrued on the Debenture to the date
of conversion,  in dollars,  and the manner in which it calculated the number of
shares issuable upon conversion.

         E. As soon as practicable after conversion,  the Debentureholder  shall
surrender the Debenture  Certificate  representing the shares being converted to
the Corporation at the Corporation's  Principal Office.  The Debentures shall be
deemed to have been converted into Preferred Stock on the date of  effectiveness
of the Preferred  Stock Amendment (the "Preferred  Stock  Conversion  Date") and
into  Common  Stock  on the  closing  date  of the  Qualified  Public  Offering,
irrespective of the date upon which the Debenture  Certificate is surrendered to
the  Corporation  in  exchange  for a  certificate  representing  the  shares of
Preferred  Stock or Common Stock,  as the case may be,  issuable upon conversion
(the "Surrender  Date"). On the Conversion Date, the Holder shall be treated for
all purposes as the record  holder of the  Preferred  Stock or Common Stock , as
the case may be, issuable upon such conversion. As promptly as practicable on or
after  the  Surrender  Date,  the  Corporation  shall  issue  a  certificate  or
certificates for the number of shares of Preferred Stock or Common Stock, as the
case may be, issuable upon conversion.

         F. Unless  specifically  requested to do otherwise by a Debentureholder
in writing, the Corporation shall be entitled to aggregate the principal amounts
of all Debentures owned by such  Debentureholder  and issue a single certificate
of  Preferred  Stock or Common  Stock,  as the case may be, to such  Holder upon
automatic conversion.

V.       Optional Conversion into Shares of Common Stock.
         ------------------------------------------------

         A.  Holder  may,  at any  time,  and from  time to time on or after (1)
approval by the  shareholders of the  Corporation of the Increase  Amendment and
(2) the earlier of (i)  effectiveness  of a registration  statement with the SEC
covering the shares of Common Stock into which the Debenture is  convertible  or
(ii) the  expiration  of 150 days from the Initial  Closing  Date (as  hereafter
defined),  convert  all or any whole  number  multiple of one  thousand  dollars
($1000) of the  principal  amount of  Debentures,  plus any  accrued  but unpaid
interest thereon, to whole shares of the Corporation's  Common Stock. The number
of shares of Common Stock issuable upon such  conversion  shall be the result of
dividing (a) the dollar amount of the principal of, and accrued interest on, the
Debenture  being  converted  by (b) the  lesser  of (i) $6.00 or (ii) 80% of the
Market Price (the "Conversion  Price").  Notwithstanding the foregoing,  for the
first 270 days following the initial closing of the offering by which any of the
Debentures were first sold (the "Initial  Closing Date"),  the Conversion  Price
shall not be less than $4.00 per share, which $4.00 price shall be appropriately
adjusted in the event of any stock splits or other transactions affecting the


                                       -6-
<PAGE>
Common Stock (the "Minimum Conversion Price").  After such 270 day period, the
Minimum Conversion Price shall be eliminated.

         B. The  Corporation  has agreed  under  terms  contained  in a separate
agreement entered between the Corporation and the  Debentureholders  to register
the shares of Common Stock issuable by the  Corporation as interest on, and upon
conversion of,  Debentures  with the SEC. In the event such  registration is not
declared  effective by the SEC within 150 days of the Initial  Closing Date, the
Conversion Price and the Minimum Conversion Price shall thereafter be reduced by
two percent (2%) from the Conversion Price or Minimum  Conversion  Price, as the
case may be, otherwise in effect at the time of conversion. The Conversion Price
shall be  reduced  an  additional  two  percent  (2%)  off the  then  applicable
Conversion  Rate for each  additional  30 days (or any  fractional  part of such
30-day period)  during which such  registration  is not effective.  Such reduced
Conversion  Price  shall  remain in  effect  for the  remainder  of the time the
Debentures remain outstanding.

         C. In order to  effect  conversion,  the  Holder  shall  surrender  the
Debenture  Certificate  representing  the  Debentures  being  converted  to  the
Corporation  at  its  principal  office,  accompanied  by  written  notice  (the
"Conversion  Notice") to the  Corporation  that the Holder elects to convert the
Debentures. The Conversion Notice shall be in the form attached to the Debenture
Certificate(s) being converted.  The Holder may submit an irrevocable Conversion
Notice to the  Corporation  in  advance  of  physical  delivery  of a  Debenture
Certificate(s)  by  transmitting  a copy  of  the  completed  Conversion  Notice
relating to the Debenture  Certificate(s)  to be tendered to the  Corporation by
facsimile (the "Advance Conversion Notice").  Physical delivery of the Debenture
Certificates  which are the subject of the Advance  Conversion  Notice  shall be
made  to  the  Corporation  within  three  (3)  business  days  thereafter.  The
Debentures tendered for conversion shall be deemed to have been converted on the
date the Corporation receives the Advance Conversion Notice for such Debentures,
provided the Advance  Conversion  Notice is received by 6:00 p.m. (Eastern Time)
on a Business Day (the "Common Stock Conversion  Date"),  and provided  further,
that the original Conversion Notice and the Debenture  Certificate  representing
the Debentures  then being  converted is actually  delivered to the  Corporation
within such three (3) business day period.  If the Advance  Conversion Notice is
received on a day that is not a Business Day or after 6:00 p.m.  (Eastern  Time)
on a day that is a Business Day, then the Common Stock  Conversion Date shall be
the next day that is a Business  Day. The Company will cause its transfer  agent
to issue  certificates  for the shares of Common Stock issuable upon  conversion
and will  transmit the  certificates  representing  such shares  (together  with
certificates or instruments  representing the balance of Debentures not being so
converted)  to the  Holder via  express  courier,  by  electronic  transfer,  or
otherwise,  within three (3) business  days after  receipt by the Company of the
original  Conversion  Notice and the Debenture  certificates  for the Debentures
being converted (the "Delivery Date"). On the Common Stock Conversion Date, such
Holder shall be treated for all such purposes as the record Holder of the Common
Stock issuable upon such conversion.



                                       -7-
<PAGE>
         D. 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
Holder.  As  compensation  to the  converting  Holder for such loss, the Company
agrees to pay a late  payment  penalty to the Holder for late  delivery  of such
shares of Common  Stock  deliverable  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 the Delivery Date):

</TABLE>
The  Company  shall  pay  any  penalties   incurred  under  this  Subsection  in
immediately  available  funds  upon  demand.  Nothing  herein  shall  limit  the
converting  Holder's right to pursue actual damages for the Company's failure to
issue and deliver the Common Stock to the  converting  Holder.  Furthermore,  in
addition to any other remedies which may be available to the converting  Holder,
in the event the Company fails for any reason to effect  delivery of such shares
of Common  Stock within five (5)  business  days after the Delivery  Date (other
than as a result of an event in the nature of a force  majeure  which is totally
beyond the control of the Company),  the converting  Holder shall be entitled to
revoke the relevant  Conversion  Notice by delivering a notice to that effect to
the  Company,  whereupon  the Company and the Holder  shall be restored to their
respective positions immediately prior to delivery of the Conversion Notice. Any
shares of Common  Stock  delivered  to Holder  after  such  revocation  shall be
forthwith  returned  to the  Company and a new  Debenture  Certificate  shall be
forthwith  issued in replacement for the Debenture for which conversion has been
so revoked.

                                       -8-
<PAGE>
         E. Only whole shares of the  Corporation's  Common Stock will be issued
on any  conversion.  In the event that a Holder of  Debentures  is entitled to a
fraction of a share of Common Stock, the Corporation  shall, at its sole option,
either  (i) pay  such  holder  the cash  equivalent  of that  fractional  share,
computed by multiplying the fraction by the applicable  Conversion Price or (ii)
the next higher whole number of shares of Common Stock if the  fractional  share
to which the  Debentureholder  is otherwise entitled is equal to 0.5 or greater,
or the next lower number of whole shares of Common Stock if the fractional share
to which the Debentureholder is otherwise entitled is less than 0.5.

         F. Subject to the  foregoing,  no payment or  adjustment  shall be made
upon  any  conversion  in  respect  of any  interest  accrued  on any  Debenture
surrendered for conversion  prior to a Interest  Payment Record Date, or for any
dividends on the Common Stock delivered upon conversion.

         G. Following  effectiveness of the Increase Amendment,  the Corporation
covenants  that it will at all  times  reserve  and keep  available,  free  from
preemptive  rights,  out of the aggregate of its authorized but unissued  Common
Stock or its issued Common Stock held in its treasury,  or both, for the purpose
of  effecting  conversions  of  Debentures,  the full number of shares of Common
Stock then  deliverable  upon the conversion of all  Outstanding  Debentures not
theretofore converted;  and if at any time the number of authorized but unissued
shares of Common Stock shall not be sufficient  to effect the  conversion of all
said Outstanding  Debentures,  the Corporation will use its best efforts to take
such  corporate  action as may in the  opinion of its  counsel be  necessary  to
increase its  authorized  but unissued  Common Stock to such number of shares as
shall be sufficient for that purpose.

         H. The Corporation will pay any and all United States Federal, state or
local documentary stamp or similar issue or transfer taxes payable in respect of
the issue or delivery of shares of Common  Stock on  conversions  of  Debentures
pursuant hereto;  provided,  however, that the Corporation shall not be required
to pay any tax which may be payable in respect of any  registration  of transfer
involved in the issue or  delivery of Common  Stock in a name other than that of
the Holder of the Debentures to be converted and no such issue or delivery shall
be made  unless  and  until the  person  requesting  such  issue has paid to the
Corporation the amount of any such tax or has  established,  to the satisfaction
of the Corporation, that such tax has been paid.

VI.  Reorganization.  If any capital  reorganization or  reclassification of the
capital stock of the Corporation,  or consolidation or merger of the Corporation
with another corporation,  or the sale of all or substantially all of its assets
to another  corporation  shall be affected in such a way that  holders of Common
Stock shall be entitled to receive  stock,  securities or assets with respect to
or in exchange for Common Stock,  then,  as a condition of such  reorganization,
reclassification,  consolidation,  merger or sale, lawful and adequate provision
shall be made whereby the Holder of Debentures  shall  thereafter have the right
to (but not be  obligated  to)  receive  upon the  basis  and upon the terms and
conditions specified herein and in lieu of the shares of the Common Stock of the
Corporation immediately theretofore

                                       -9-
<PAGE>
receivable upon the conversion of Debentures,  such shares of stock,  securities
or assets as may be issued or payable  with  respect to or in  exchange  for the
outstanding shares of such Common Stock of the Corporation, and in any such case
appropriate  provision  shall be made with respect to the rights and interest of
the  Debentureholders  to the end that the provisions hereof (including  without
limitation provisions for the number of shares receivable upon the conversion of
the  Debentures and the method for  calculation  of the Conversion  Price) shall
thereafter  be  applicable,  as nearly as may be, in  relation  to any shares of
stock,  securities or assets  thereafter  receivable upon the conversion of such
Debentures.  The Corporation shall not effect any such consolidation,  merger or
sale,  unless prior to the  consummation  thereof the successor  corporation (if
other than the Corporation)  resulting from such  consolidation or merger or the
Corporation  purchasing such assets shall assume by written instrument  executed
and mailed to the Holders, the obligation to deliver to such Holders such shares
of stock,  securities or assets as, in accordance with the foregoing provisions,
such Holders may be entitled to receive.

VII.     Notice of Certain Events.  If, at any time:
         ------------------------- 

     A. The Corporation shall declare any cash dividend on its Common Stock;

     B. the Corporation  shall pay any dividend payable in stock upon its Common

due, with respect to, or interest on, any Superior  Indebtedness (as hereinafter
defined in Section  XII),  or any default,  or any event  which,  with notice or
lapse of time or both, would constitute a default, in any other agreement,  term
or condition contained in any agreement under which any Superior Indebtedness is
issued, no cash payment of principal or interest shall be made on the Debentures
unless  and until such  default  shall  have been  remedied,  nor shall any such
payment be made if after giving  effect,  as if paid, to such payment,  any such
default  would  exist  in the  performance  or  observance  of any  covenant  or
agreement of the Corporation contained in any agreement under which any Superior
Indebtedness  shall have been issued or pursuant to which Superior  Indebtedness
shall have been incurred.

         B. Upon any payment by the  Corporation,  or  distribution of assets of
the  Corporation  of any  kind  or  character,  whether  in  cash,  property  or
securities,  to creditors upon any dissolution or winding-up or total or partial
liquidation  or  reorganization   of  the  Corporation,   whether  voluntary  or
involuntary or in bankruptcy, insolvency, receivership or other proceedings, all
amounts due or to become due upon all Superior  Indebtedness shall first be paid
in full,  or  payment  thereof  provided  for,  in money or  money's  worth,  in
accordance  with  its  terms,  before  any  payment  is made on  account  of the
principal (and premium, if any) or interest on the Debentures; and upon any such
dissolution or winding-up or liquidation or  reorganization,  any payment by the
Corporation,  or  distribution  of  assets  of the  Corporation  of any  kind or
character,   whether   in  cash,   property   or   securities,   to  which   the
Debentureholders  would  otherwise  be entitled but for the  provisions  of this
Section VIII,  shall be paid by the  Corporation or by any receiver,  trustee in
bankruptcy,  liquidating trustee,  custodian,  agent or other person making such
payment or  distribution  directly to the holders of  Superior  Indebtedness  or
their  representative or representatives or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing any Superior Indebtedness
may have been issued,  as their respective  interests may appear,  to the extent
necessary to pay all Superior  Indebtedness  in full, in money or money's worth,
after giving  effect to any  concurrent  payment or  distribution  to or for the
holders of Superior Indebtedness,  before any payment or distribution is made to
the Holders of the Debentures.

         C. In the event that  notwithstanding  the  preceding  paragraphs,  any
payment or  distribution  of assets of the Corporation of any kind or character,
whether in cash, property or securities,  prohibited by the preceding paragraphs
shall be received by the holders of the

<PAGE>
Debentures,  such payment or distribution shall be paid over or delivered to the
holders of Superior Indebtedness of their representative or representatives,  or
to the trustee or trustees under any indenture pursuant to which any instruments
evidencing any Superior  Indebtedness may have been issued,  as their respective
interests  may  appear,   for   application  to  the  payment  of  all  Superior
Indebtedness  remaining  unpaid  to the  extent  necessary  to pay all  Superior
Indebtedness  in full in money or money's  worth in  accordance  with its terms,
after giving  effect to any  concurrent  payment or  distribution  to or for the
holders of such Superior Indebtedness.

         D. For purposes of this Section  VIII,  the words,  "cash,  property or
securities" shall not be deemed to include shares of stock of the Corporation as
reorganized  or  readjusted,  or  securities  of the  Corporation  or any  other
corporation  provided  for by a plan  of  reorganization  or  readjustment,  the
payment of which is subordinated at least to the extent provided in this Section
VIII with respect to the Debentures to the payment of all Superior  Indebtedness
which  may  at  the  time  be  outstanding;   provided  that  (i)  the  Superior
Indebtedness is assumed by the new corporation,  if any, resulting from any such
reorganization  or  readjustment,  and (ii) the  rights  of the  holders  of the
Superior  Indebtedness are not, without the consent of such holders,  altered by
such reorganization or readjustment.  The consolidation of the Corporation with,
or the merger of the Corporation into, another corporation or the liquidation or
dissolution of the Corporation  following the  conveyance,  lease or transfer of
its  property  as an  entirety,  or  substantially  as an  entirety,  to another
corporation upon the terms and conditions  provided in Section VIII hereof shall
not be deemed a dissolution,  winding-up,  liquidation or reorganization for the
purposes  of this  Section if such other  corporation  shall,  as a part of such
consolidation, merger, conveyance, lease or transfer, comply with the conditions
stated in Section VIII hereof.

         E.  Subject to the payment in full of all  Superior  Indebtedness,  the
rights of the holders of the Debentures shall be subrogated to the rights of the
holders of Superior  Indebtedness to receive  payments or distributions of cash,
property  or   securities  of  the   Corporation   applicable  to  the  Superior
Indebtedness  until the principal of (and  premium,  if any) and interest on the
Debentures shall be paid in full; and, for the purposes of such subrogation,  no
payments or  distributions  to the holders of the Superior  Indebtedness  of any
cash, property or securities to which the Holders of the Debentures or a Trustee
would be entitled except for the provisions of this Section, and no payment over
pursuant  to  the  provisions  of  this  Section  to  the  holders  of  Superior
Indebtedness by Holders of the Debentures or the Trustee,  shall, as between the
Corporation, its creditors other than holders of Superior Indebtedness,  and the
Holders of the Debentures, be deemed to be a payment by the Corporation to or on
account of the Superior  Indebtedness.  It is understood  that the provisions of
this  Section  are and are  intended  solely  for the  purpose of  defining  the
relative  rights of the  Holders  of the  Debentures,  on the one hand,  and the
holders of the Superior Indebtedness, on the other hand.

         F.  The  terms  "paid in full"  and  "payment  in full" as used in this
Section  with  respect to Superior  Indebtedness  mean the  receipt,  in cash or
securities (taken at their market

                                      -12-
<PAGE>
value  at the time of the  receipt  thereof),  of the  principal  amount  of the
Superior Indebtedness (and any premium due thereon) and full interest thereon to
the date of such  payment of principal  and all other  amounts due to holders of
Superior  Indebtedness  pursuant to the provisions of the instruments  providing
therefor.

         G. Nothing  herein shall be construed as  preventing a  Debentureholder
from  converting  Debentures  to Common  Stock  during any period of  continuing
default  respecting  Superior  Indebtedness,  nor  shall  a  Debentureholder  be
prohibited  from selling any shares of Common Stock issued upon such  conversion
which are otherwise saleable.

IX.      Redemption.
         -----------

         A. The  Debentures  may be redeemed in whole or in part at the election
of the  Corporation  upon not less than 30 nor more than 60 days  prior  written
notice by mail, at any time up to 270 days  following the Initial  Closing Date,
if,  during such 270 day period,  the closing bid price for the Common Stock for
any 20 trading  days within any 30  consecutive  trading day period as quoted on
the OTC Electronic Bulletin Board (or such other quotation service as is quoting
bid and asked  prices for the Common  Stock),  or the  closing bid price for the
Common  Stock as  reported  by the  NASDAQ  Stock  Market or any other  national
exchange upon which the Common Stock is listed for trading which has closing bid
reporting, is less than the Minimum Conversion Price per share.  Notwithstanding
the  foregoing,  if the 20 day period during which the price of the Common Stock
is less than the Minimum Conversion Price falls totally with the last 60 days of
the 270 days following the Initial  Closing Date, the  Corporation  shall have a
full 60 days from the end of such 270 day period to exercise its rights of early
redemption.

         B. To redeem the Debentures, the Corporation shall pay the Holders 118%
of the principal face amount of the  Debentures  being  redeemed,  together with
accrued but unpaid  interest  owing to the date of  redemption.  Any  Debentures
which are redeemed in part only shall be redeemed in principal amounts of $1,000
or whole multiples of $1,000.

"Redemption Notice") shall state the Redemption Date, the Paying Agent with whom
funds  sufficient to make the  redemption  have been  deposited,  and the dollar
amount of  principal  and  interest to be redeemed  from each such  holder.  Any
partial redemption shall be pro rata as between the Debenture holders.

         D.  Notwithstanding  the above,  any  Debentureholder  may  convert the
principal  and  accrued  interest  so called for  redemption  into shares of the
Corporation's Common Stock at any time prior to the Redemption Date if, prior to
such date,  the Increase  Amendment  has been  approved by  shareholders  of the
Corporation.

X.  Periodic  Reports.  
    ------------------  
     Debentureholders  shall be sent  the same  reports  of the  Corporation  as
holders of Common Stock are sent,  at the same time as sent to holders of Common
Stock.

    ------------------
     The Corporation  shall cause to be kept at its principal  office a register
in which,  subject  to such  reasonable  regulations  as it may  prescribe,  the
Corporation   shall  provide  for  the   registration   of  Debentures  and  the
registration of transfers of Debentures.

         At the option of the  Holder,  Debentures  may be  exchanged  for other
Debentures,  of  a  like  aggregate  principal  amount  upon  surrender  of  the
Debentures to be  exchanged.  Whenever any  Debentures  are so  surrendered  for
exchange, the Corporation shall execute the Debentures which the Debentureholder
making the exchange is entitled to receive.

         Subject to reasonable bonding, indemnification or other requirements as
the Corporation may determine,  the  Corporation  shall replace lost,  stolen or
mutilated Debenture certificates with replacement certificates.

other  provision of this Debenture  Agreement)  payment of the principal of (and
premium,  if any) or interest on, or conversion of, any  Debentures  need not be
made on such date, but may be made on the next succeeding  Business Day with the
same  force and  effect as if made on the  nominal  date of any such  Redemption
Date, or on such last date for conversion,  and no interest shall accrue for the
period from and after any such nominal date.

         J.  No  right  or  remedy  herein  conferred  upon or  reserved  to the
Debentureholders  is intended to be exclusive of any other right or remedy,  and
every right and remedy shall, to the extent  permitted by law, be cumulative and
in addition to every other right and remedy given  hereunder or now or hereafter
existing at law or in equity or  otherwise.  The  assertion or employment of any
right or remedy  hereunder  or  otherwise,  shall  not  prevent  the  concurrent
assertion or employment of any other appropriate right or remedy.

         K. No recourse under or upon any  obligation,  covenant or agreement of
this Debenture  Agreement or the  Debentures,  or for any claim based thereon or
otherwise  in  respect   thereof,   shall  be  had  against  any   incorporator,
stockholder,  officer,  director or agent, as such, past,  present or future, of
the Corporation or of any successor corporation,  either directly or through the
Corporation,  whether by virtue of any constitution,  statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that the obligations  hereunder are solely  corporate  obligations of
the Corporation,  and that no such personal  liability whatever shall attach to,
or is or  shall be  incurred  by,  the  incorporators,  stockholders,  officers,
directors  or  agents,   as  such,  of  the  Corporation  or  of  any  successor
corporation,  or any of them, because of the creation of the indebtedness hereby
authorized,  or under or by reason of the  obligations,  covenants or agreements
contained in this Debenture  Agreement or the  Debentures or implied  therefrom;
and that any and all such personal liability,  either at common law or in equity
or by  constitution  or  statute,  of,  and any and all such  rights  and claims
against,  every such incorporator,  stockholder,  officer or director,  as such,
because of the creation of the indebtedness hereby

                                      -19-

authorized,  or under or by reason of the  obligations,  covenants or agreements
contained in this Debenture  Agreement or the Debentures,  or implied therefrom,
are  hereby   expressly  waived  and  released  as  a  condition  of  and  as  a
consideration for, the issue of such Debentures.

                                    EXHIBIT A

                       DESIGNATION OF SERIES A 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
A Cumulative Convertible Redeemable Preferred Stock as follows:

1.                DESIGNATION

                   Four  Million   (4,000,000)   shares  of  the   Corporation's
15,000,000  total  authorized  shares of no par value preferred stock are hereby
designated  as  Series  A  Cumulative  Convertible  Redeemable  Preferred  Stock
(hereinafter referred to as the "Series A Preferred").

2.                STATED VALUE

                  The Series A Preferred shall have a stated value of one dollar
($1.00) per share (hereafter the "Stated Value").

3.                DIVIDENDS

                  a. Right to Dividends and Initial  Dividend  Rate. The holders
of  outstanding  Series A  Preferred  shall be  entitled  to receive  cumulative
dividends at the initial rate of eight percent (8%) per share, per annum,  based
on the Stated Value of the Series A Preferred. Cumulative dividends shall accrue
and be paid  quarterly  to record  holders of Series A Preferred as of March 31,
June 30,  September  30 and  December  31 of each  year  (the  "Dividend  Record
Dates"), in arrears, if, as and when declared by the Board of Directors,  out of
assets at the time legally available for such dividends.

                  b.  Adjustment of Dividend Rate.  The dividend  payable on the
Series A Preferred  shall be reduced to four percent (4%) per annum upon initial
effectiveness  of a registration  statement with the United State Securities and
Exchange  Commission  (the "SEC") covering the shares of Common Stock into which
the Series A Preferred is  convertible.  Thereafter,  interest shall continue at
such rate until all of the Series A Preferred has been converted to Common Stock
or all shares of the Series A Preferred have been redeemed by the Corporation.



<PAGE>
                  c. Payment Dates for Dividends.  Dividends shall be paid on or
before the 15th of the month following each Interest Payment Record Date, or the
next Business Day thereafter if such day is not a Business Day.

                  d.  Payment  of  Dividends.  The  Corporation  shall  pay  all
dividends  on the Series A Preferred  in shares of its no par value common stock
(the "Common Stock") to the extent the  Corporation  has a sufficient  number of
shares of Common Stock available to pay such  dividends.  Shares of Common Stock
used to pay dividends may be authorized and unissued  shares or treasury  shares
of the Corporation. The Corporation agrees to use its best efforts to maintain a
sufficient  number of shares of Common Stock available at all times to allow for
the payment of dividends on the Series A Preferred in shares of Common Stock. If
the Corporation  has an insufficient  number of shares of Common Stock available
at any time to pay all  dividends  then  owing in shares of  Common  Stock,  the
Corporation  may pay all or any part of such dividend in cash or other  property
(including  other  securities  of the  Corporation)  having a value equal to the
dividend then payable.

                  e. Number of Shares of Common Stock Issuable as Dividends. For
any  dividend  being  paid in shares of Common  Stock,  the  number of shares of
Common Stock  issuable per share of Series A Preferred  shall be  calculated  as
follows:  The  amount of the  dividend  owing on the Series A  Preferred  at the
Dividend  Record Date (in dollars)  shall be divided by the average  closing bid
price of the Common  Stock over the last five trading days prior to the Dividend
Record  Date as quoted  on the OTC  Electronic  Bulletin  Board,  or such  other
quotation  service as is quoting bid and asked prices for the Common  Stock.  If
the Common Stock is then listed on the NASDAQ Stock Market or any other national
exchange  which has  closing  bid price  reporting,  the five day average of the
closing  bid price for the Common  Stock for such days as  reported on NASDAQ or
such other national  securities  exchange shall be substituted  for the five day
average  closing bid price as reported by the OTC  Electronic  Bulletin Board or
other  quotation  service.  In the event the  Common  Stock is not quoted on any
exchange  or  quotation  service,  then the Board of  Directors,  acting in good
faith,  shall  adopt a  resolution  valuing  the Common  Stock for  purposes  of
determining  the number of shares of Common Stock issuable as a dividend at such
Dividend  Record  Date.  The price of the  Common  Stock  used for  purposes  of
determining the number of shares issuable as dividends on the Series A Preferred
or for  purposes of  conversion  of  Debentures  into Common  Stock  pursuant to
Section 5 of this  designation is hereafter  referred to as the "Market  Price."
When computed in connection with a conversion transaction,  the average shall be
computed using the five trading days prior to the Conversion Date.

                  f. Payment of  Dividends  to Holders  Based on Total Shares of
Series A Preferred  Registered in the Name of Such Holder.  Notwithstanding  the
number of certificates held by an individual  holder of Series A Preferred,  the
Corporation  shall be entitled to cumulate the number of shares  represented  by
all such  certificates  held in the name of the same holder,  and the cumulative
total  shall then be  multiplied  by the number of Common  Shares  issuable as a
dividend per share of Series A Preferred to determine the total number of shares
of Common Stock issuable to such holder at each Dividend Record Date.

                                       -2-
<PAGE>
                  g. No Issuance of Fractional  Shares.  No fractional shares of
Common Stock will be issued as a dividend on the Series A Preferred;  rather,  a
holder of Series A Preferred  otherwise entitled to a fractional share of Common
Stock as a dividend may receive,  at the sole option of the Corporation,  either
(i) cash in lieu of such fractional  share, or (ii) the next higher whole number
of  shares of  Common  Stock if the  fractional  share to which  such  holder is
otherwise entitled is equal to 0.5 or greater, or the next lower whole number of
shares of Common Stock if the fractional share to which such holder is otherwise
entitled is less than 0.5.

                  h. Dividend Statements.  At the time of each dividend payment,
the Corporation shall provide each holder of Series A Preferred with a statement
showing the manner in which it calculated the dividend  payable at such Dividend
Record Date, including the calculation used to determine the number of shares of
Common Stock issued as such dividend.

                  i. Place of Dividend Payment.  Dividends shall be payable, and
transfer of the Series A Preferred will be registrable,  at the Principal Office
of the  Company.  Upon  request  by a holder of Series A  Preferred,  payment of
dividends  shall be made by delivery of a check or Common Stock  certificates to
the  registered  holder  mailed to such  holder's  address  as it appears on the
Series A Preferred register.

                  j.  Priority  of  Dividends.  The  Corporation  shall  make no
Distribution  (as defined  below) to the  holders of Common  Stock in any fiscal
year unless and until any and all unpaid dividends shall have been paid upon all
Series A Preferred. "Distribution" as used in this Section means the transfer of
cash or property without consideration,  whether by way of dividend or otherwise
(except a dividend in shares of the Corporation),  or the purchase or redemption
of shares of the Corporation for cash or property,  but does not include (i) the
repurchase of shares from a terminated employee or consultant of the Corporation
within  the  terms  of an  agreement  approved  by the  Corporation's  Board  of
Directors  or (ii) a  distribution  which  is part of a  voluntary  liquidation,
dissolution or winding up of the Corporation.

                  k. Dividends  Cumulative.  All dividends owing on the Series A
Preferred  shall be  cumulative.  Dividends  shall accrue or  accumulate  to the
extent they are unpaid.  Unpaid  dividends shall bear and accrue interest at the
same rate  applicable  to the Series A Preferred  as of the time of the Dividend
Record  Date for the  unpaid  dividend.  The  unpaid  dividends,  together  with
interest  thereon,  shall be paid as soon as the  Corporation is legally able to
pay any such dividends and interest.  Interest on unpaid dividends shall also be
paid in shares of Common Stock, if possible, with the number of shares of Common
Stock issuable as interest being calculated in the same manner as for dividends.

4.                LIQUIDATION PREFERENCE

     a. Basic  Preference  Rights.  In the event of any voluntary or involuntary
liquidation, dissolution, or winding up of the Corporation (a "Liquidation"):

                                       -3-
<PAGE>
          (1) Payments to Holders of Series A  Preferred.  Each holder of shares
     of Series A  Preferred  then  outstanding  shall be  entitled to receive an
     amount  equal to $1.00 for each share of Series A Preferred  (the "Series A
     Liquidation Preference"),  plus all accrued and unpaid dividends thereon to
     the date  fixed  for  distribution,  before  any  payment  shall be made in
     respect of the Corporation's Common Stock.

          (2) Payments to Holders of Common  Stock.  After payment has been made
     to the holders of Series A Preferred  of the full amounts to which they are
     entitled under Paragraph  4(a)(1) above,  the holders of Common Stock shall
     be entitled to receive all  declared  and unpaid  dividends  thereon to the
     date fixed for distribution.

          (3)  Should  Assets  Exceed  Payments.  The  remaining  assets  of the
     Corporation  available for distribution to shareholders  after payments are
     made under Paragraphs  4(a)(1) and 4(a)(2) above,  shall be distributed pro
     rata among all of the  Corporation's  shareholders.  For  purposes  of this
     Paragraph  4(a)(3),  holders  of  Series A  Preferred  shall  share in this
     distribution  in  proportion  to the number of shares of Common  Stock they
     would hold had full conversion of their Series A Preferred  occurred on the
     day prior to the Liquidation, according to the provisions of Sections 5 and
     6, below.

          (4) Should Assets Be Insufficient. If upon a Liquidation the assets of
     the Corporation  available for  distribution to its  shareholders  shall be
     insufficient  to make full payments due under Paragraph  4(a)(1),  then the
     holders of the Series A Preferred then  outstanding  shall share ratably in
     proportion  to the total  number of such shares  owned by each such holder,
     first in proportion to the respective Series A Liquidation Preference,  and
     next, in proportion to the amount of unpaid dividends.

          (5) Source of Liquidation  Payment. The holders of stock shall be paid
     under this Subsection  4(a) out of the assets of the Corporation  available
     for  distribution  to  shareholders,   whether  from  capital,  surplus  or
     earnings.

          (6) Merger or Acquisition.  The Corporation shall not effect a merger,
     reorganization,  or  consolidation  of the Corporation into or with another
     corporation  or the sale or  transfer  of all or  substantially  all of the
     assets of the Corporation  until the Corporation shall have provided notice
     to all holders of Series A Preferred  pursuant to Subsection  4(b),  below.
     Unless  otherwise  agreed to by the  holders of a majority  of the Series A
     Preferred   which   is   then   outstanding,   a   merger,   consolidation,
     reorganization  or sale of all or  substantially  all of the  Corporation's
     assets shall be deemed to be a Liquidation.


     b. Notice.  In the event of any Liquidation of the  Corporation,  or in the
event of any merger, reorganization, or consolidation of the Corporation into or
with another corporation, or the sale or transfer of all or substantially all of
the assets of the Corporation,  the Corporation shall give each holder of Series
A Preferred  initial  written notice of the proposed  action within fifteen (15)
days after the date the Board of Directors approves such

                                       -4-
<PAGE>
action, or twenty (20) days prior to any shareholders' meeting called to approve
such  action,  or twenty  (20) days after the  commencement  of any  involuntary
proceeding, whichever is earlier.

          (1) Content of Notice.  Such  initial  written  notice  (the  "Initial
     Notice")  shall  describe the material terms and conditions of the proposed
     action,  including a  description  of the stock,  cash,  and property to be
     received  by the  holders of Series A Preferred  upon  consummation  of the
     proposed  action.  If any  material  change  in the  facts set forth in the
     Initial  Notice shall occur,  the  Corporation  shall promptly give another
     written  notice  (the  "Subsequent  Notice") to each holder of the Series A
     Preferred of that material change.

          (2) Notice Precedes Consummation. The Corporation shall not consummate
     any  Liquidation  of the  Corporation  before the expiration of twenty (20)
     days  after the  mailing of the  Initial  Notice or ten (10) days after the
     mailing of any Subsequent  Notice,  whichever is later. But any such 20-day
     or 10-day period may be shortened  upon the written  consent of the holders
     of a majority of the Series A Preferred then outstanding.

          c.  Non-Cash  Distributions  on  Liquidation.  In  the  event  of  any
     Liquidation  of the  Corporation  which will  involve the  distribution  of
     assets other than cash, the  Corporation  shall promptly engage a competent
     independent   appraiser  to  determine  the  value  of  the  assets  to  be
     distributed.  With respect to the valuation of securities,  the Corporation
     shall  engage  such  appraiser  as shall be  approved  by the  holders of a
     majority of the Series A Preferred then outstanding. The Corporation shall,
     upon receipt of such appraiser's  valuation,  give prompt written notice to
     each holder of shares of Series A Preferred of the appraiser's valuation.

5.                CONVERSION

                  a.        Conversion Rights.

          (1)  Optional  Conversion.  Each share of Series A Preferred  shall be
     convertible,  at the  option of the  holder  thereof,  into  fully paid and
     non-assessable  shares of Common Stock of the Corporation at any time after
     the date of issuance and following (a) the  authorization of an increase in
     the Corporation's authorized Common Stock to no less than 40,000,000 shares
     and  (b)  the  first  to  occur  of (i)  effectiveness  with  the  SEC of a
     registration  statement  covering the shares of Common Stock  issuable upon
     conversion of the Series A Preferred or (ii) the lapse of 150 days from the
     Initial  Closing Date. The Series A Preferred shall be so convertible up to
     and  including  the  earlier  of (i)  the day  prior  to the  closing  of a
     Qualified  Public  Offering  (as  defined  below) or (ii) the day fixed for
     redemption  of any  and  all  remaining  outstanding  shares  of  Series  A
     Preferred (the "Conversion Period").

          (2) Automatic Conversion. All outstanding shares of Series A Preferred
     shall automatically be converted into fully paid and non-assessable  shares
     of
                                       -5-
<PAGE>
     Common Stock of the  Corporation,  at the then applicable  Conversion Price
     (as defined below),  immediately  prior to the closing of a firm commitment
     underwritten  public  offering  of  the  shares  of  Common  Stock  of  the
     Corporation pursuant to a registration statement filed under the Securities
     Act of 1933, as amended,  at a price per share of not less than ten dollars
     ($10.00)  per share  (prior to  underwriter  commissions  and  expenses and
     adjusted for stock splits,  stock dividends,  reorganizations and the like)
     and with aggregate  gross offering  proceeds to the Corporation of not less
     than Five Million Dollars ($5,000,000) (a "Qualified Public Offering").

     b. Conversion Formula.  Each share of Series A Preferred shall be valued at
one dollar  ($1.00)  (the  "Series A Purchase  Price")  for  purposes  of either
optional  or  automatic  conversion,  notwithstanding  any  accrued  but  unpaid
dividends owing on the Series A Preferred at the time of conversion.  The number
of shares of Common Stock into which each share of the Series A Preferred  shall
be converted  shall be determined by dividing the Series A Purchase Price by the
Series  A  Conversion  Price  or the  Minimum  Series  A  Conversion  Price  (as
determined as provided  below) which is in effect at the time of the conversion.
The  Corporation  shall make  provision  for all  necessary  payments  as of the
Conversion  Date or Automatic  Conversion  Date (as defined in Subsection  5(d),
below) on account of any dividends  accrued and unpaid on the Series A Preferred
surrendered for conversion.

     c. Conversion Price.

          (1) The  conversion  price per share at which  shares of Common  Stock
     shall be  initially  issuable  upon  conversion  of any  shares of Series A
     Preferred (the "Series A Conversion Price") shall be equal to the lesser of
     (i) $6.00 or (ii) 80% of the Market Price.  Notwithstanding  the foregoing,
     for the first 270 days  following  the initial  closing of the  offering by
     which the Debentures  (which were  converted into Series A Preferred)  were
     sold to investors (the "Initial Closing Date"),  the Conversion Price shall
     be not less than $4.00 per share,  which $4.00 price shall be appropriately
     adjusted in the event of any stock splits or other  transactions  affecting
     the Common Stock (the "Minimum Series A Conversion Price").  After such 270
     day period, the Minimum Series A Conversion Price shall be eliminated.  The
     Minimum Series A Conversion price shall be further subject to adjustment as
     provided in Section 6 below.

          (2) The  Corporation  has agreed  under terms  contained in a separate
     agreement  entered  between  the  Corporation  and the  holders of Series A
     Preferred  to  register  the  shares  of  Common  Stock   issuable  by  the
     Corporation  as dividends on, and upon  conversion  of, Series A Preferred,
     with the SEC. In the event such  registration is not declared  effective by
     the SEC within 150 days of the Initial  Closing Date, the Conversion  Price
     or the Minimum  Conversion  Price, as then applicable,  shall thereafter be
     reduced by two percent (2%) from the Conversion Price or Minimum Conversion
     Price otherwise in effect at the time of conversion.  The Conversion  Price
     or Minimum Conversion Price shall be reduced an additional two percent (2%)
     off the then applicable Conversion Price or

                                       -6-
<PAGE>
     Minimum  Conversion  Price for each  additional 30 days (or any  fractional
     part  of  such  30-day  period)  during  which  such  registration  is  not
     effective.  Such reduced Conversion Price or Minimum Conversion Price shall
     thereafter be effective  until all Series A Preferred has been converted or
     redeemed.

     d. Mechanics of Conversion.

          (1) Optional Conversion.  Before any holder of Series A Preferred will
     be entitled to convert  the same into  shares of Common  Stock  pursuant to
     Paragraph  5(a)(1)  hereof,  such holder shall surrender the certificate or
     certificates  therefor,  duly endorsed, at the office of the Corporation or
     of any transfer  agent for the Series A  Preferred,  and shall give written
     notice to the Corporation at such office that such holder elects to convert
     the same and will state therein the name or names in which the  certificate
     or  certificates   for  shares  of  Common  Stock  should  be  issued  (the
     "Conversion Notice"). The Conversion Notice shall be in the form printed on
     the certificate(s) representing the Series A Preferred being converted. The
     Holder may submit an irrevocable  Conversion  Notice to the  Corporation in
     advance  of  physical  delivery  of a  specific  Series A  Preferred  share
     certificate(s)  by transmitting a copy of the completed  Conversion  Notice
     relating  to the  specific  certificate(s)  of  Series  A  Preferred  to be
     tendered to the  Corporation  for  conversion  by facsimile  (the  "Advance
     Conversion  Notice"),  followed  by  delivery  to  the  Corporation  of the
     certificate(s)  representing  the shares of Series A Preferred that are the
     subject of the Advance  Conversion  Notice  within three (3) business  days
     thereafter.   The  Series  A  Preferred   certificate(s)  so  tendered  for
     conversion  shall  be  deemed  to  have  been  converted  on the  date  the
     Corporation  receives  the  Advance  Conversion  Notice  for such  Series A
     Preferred (the "Conversion  Date"),  provided the Advance Conversion Notice
     is received by 6:00 p.m.  (Eastern  Time) on a Business  Day,  and provided
     further, that the certificate representing the shares of Series A Preferred
     then being converted is actually  delivered to the Corporation  within such
     three (3)  business  day period.  If the Advance  Conversion  Notice is not
     received  on a Business  Day or by 6:00 p.m.  (Eastern  Time) on a Business
     Day,  then the  Conversion  Date for the  Series A  Preferred  to which the
     Advance  Conversion  Notice relates shall be deemed to have occurred on the
     next day which is a Business Day. The Company will cause its transfer agent
     to  issue  certificates  for the  shares  of  Common  Stock  issuable  upon
     conversion  and will  transmit the  certificates  representing  such shares
     (together  with  certificates  representing  the  balance  of any shares of
     Series A  Preferred  not being so  converted)  to the  Holder  via  express
     courier, by electronic  transfer,  or otherwise,  within three (3) business
     days after receipt by the Company of the original Conversion Notice and the
     Series A Preferred  certificates  being converted (the "Delivery Date"). If
     the Holder in whose  name the  Series A  Preferred  being  surrendered  for
     conversion  requests that the Corporation  issue shares of Common Stock (or
     shares  of  Series A  Preferred  in  replacement  for  shares  of  Series A
     Preferred  not  being  converted  at the  time) in a name  other  than such
     holder's,  then such  holder  shall be  required  to  demonstrate,  at such
     holder's expense and to the Corporation's  satisfaction,  that an exemption
     from registration  under federal and state securities laws is available for
     the requested  issuance of shares. The Corporation may require the delivery
     of an opinion of counsel to the effect that such an exemption is available

                                       -7-
<PAGE>
     for  the   transaction.   Conversion  shall  be  deemed  to  have  occurred
     immediately  prior to the close of business on the date of surrender of the
     certificate(s)  for shares of Series A Preferred  being converted or in the
     case of an Advance  Conversion  Notice,  the date such  Advance  Conversion
     Notice is deemed received by the Corporation as provided above.  The person
     or persons  entitled to receive the shares of Common  Stock  issuable  upon
     such  conversion  shall be treated for all purposes as the record holder or
     holder of such shares of Common Stock on such Conversion Date.

          (2) Penalty  for Late  Delivery of Share  Certificates  Issuable  upon
     Conversion.  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 Holder. As compensation to the converting Holder for such loss,
     the Company agrees to pay a late payment  penalty to the converting  Holder
     for late  delivery of such shares of Common  Stock 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 the Delivery Date):

</TABLE>

The Company shall pay any penalties incurred under this Paragraph in immediately
available funds upon demand.  Nothing herein shall limit the converting Holder's
right to pursue actual  damages for the  Company's  failure to issue and deliver
the Common Stock to the converting Holder. Furthermore, in addition to any other
remedies  which may be  available  to the  converting  Holder,  in the event the
Company  fails for any reason to effect  delivery of such shares of Common Stock
within five (5) business days after the Delivery Date (other than as

                                       -8-
<PAGE>
a result of an event in the nature of a force  majeure  which is totally  beyond
the control of the Company),  the converting  Holder shall be entitled to revoke
the  relevant  Conversion  Notice by  delivering  a notice to that effect to the
Company,  whereupon  the  Company  and the  Holder  shall be  restored  to their
respective positions immediately prior to delivery of the Conversion Notice. Any
shares of Common  Stock  delivered  to Holder  after  such  revocation  shall be
forthwith  returned to the Company and a replacement  certificate for the shares
of Series A Preferred  shall be forthwith  issued in replacement  for the shares
for which conversion has been so revoked.

          (3) Automatic Conversion.  Conversion of all the outstanding shares of
     Series A  Preferred  into  shares of Common  Stock  pursuant  to  Paragraph
     5(a)(2)  hereof  shall  be  deemed  to have  been  made  automatically  and
     immediately  prior to the closing of a Qualified  Public  Offering,  as set
     forth in Paragraph 5(a)(2) hereof (an "Automatic  Conversion  Date").  Upon
     such automatic  conversion,  the person or persons  entitled to receive the
     shares of Common Stock  issuable upon such  conversion  will be treated for
     all  purposes as the record  holder or holders of such Common  Stock on the
     Automatic  Conversion Date whether or not such holder or holders shall have
     surrendered  certificates for such holder's shares of Series A Preferred to
     the  Corporation.  Upon the Automatic  Conversion  Date,  the  certificates
     representing  all the shares of Series A Preferred shall be deemed void; as
     soon as  practicable  after  the  surrender  by any  holder  of a  Series A
     Preferred certificate, accompanied by a statement from the holder as to the
     name or names in which the certificate or certificates for shares of Common
     Stock should be issued  (subject to the right of the Corporation to require
     proof  satisfactory to it,  including an opinion of counsel,  demonstrating
     that  a  registration  exemption  is  available  under  federal  and  state
     securities  laws for any  transfer of shares into a name other than that of
     the  original  holder),  the  Corporation  shall  issue and deliver to such
     holder or such holder's nominee or nominees,  a certificate or certificates
     for the number of shares of Common Stock to which the holder is entitled.

          (4) New Certificates.  Upon conversion of only a portion of the number
     of shares of Series A Preferred  represented  by a certificate  surrendered
     for conversion,  the  Corporation  shall issue and deliver upon the written
     order of the holder at the expense of the  Corporation,  a new  certificate
     covering  the  number  of shares of  Series A  Preferred  representing  the
     unconverted portion of the certificate so surrendered.  The Corporation may
     charge  a  reasonable  fee  for  any  transfer  of  a  Series  A  Preferred
     Certificate into the name of any person who is not the original Holder.

          (5) Payment of Accrued but Unpaid  Dividends on  Conversion.  If there
     remain  any  accrued  and  unpaid  dividends  on Series A  Preferred  being
     converted,  the  Corporation  shall pay such  dividends  to the  converting
     holder at the time of conversion in the form of additional shares of Common
     Stock,  determined  by dividing  the amount of the unpaid  dividends  to be
     applied  for  such  purpose  by the  Series  A  Conversion  Price  (or,  if
     applicable, the Minimum Series A Conversion Price) then in effect.


                                       -9-
<PAGE>
          (6) No Fractional  Shares.  The Corporation  shall issue no fractional
     shares  of  Common  Stock or scrip  upon  conversion  of shares of Series A
     Preferred.  If  more  than  one  share  of  Series  A  Preferred  shall  be
     surrendered  for conversion at any one time by the same holder,  the number
     of full shares of Common  Stock  issuable  upon their  conversion  shall be
     computed  on the  basis of the  aggregate  number  of  shares  of  Series A
     Preferred  surrendered  for  conversion  by  such  holder.  Instead  of any
     fractional  shares of Common Stock which would  otherwise be issuable  upon
     conversion of any shares of Series A Preferred, the Corporation may, at its
     sole option,  pay a cash adjustment in respect of such fractional  share in
     an amount equal to the same  fraction of the Series A  Conversion  Price or
     Minimum  Series A Conversion  Price in effect as of the day of  conversion,
     or, in lieu of cash,  issue to such holder the next higher  whole number of
     shares  of Common  Stock if the  fractional  share to which  the  holder is
     otherwise entitled is equal to 0.5 or greater,  or the next lower number of
     whole shares of Common Stock if the fractional share to which the holder is
     otherwise entitled is less than 0.5.

     e. Taxes  Incident to  Conversion.  The  Corporation  shall pay any and all
issue  taxes and other  taxes  (excluding  income  taxes) that may be payable in
respect to any issue or  delivery  of shares of Common  Stock on  conversion  of
Series A Preferred.  The Corporation  shall not be required to pay any tax which
may be payable in respect of any transfer  involved in the issue and delivery of
shares of Common Stock in a name other than that in which the Series A Preferred
so converted was registered,  and no such issue or delivery shall be made unless
and until the  person  requesting  such  issue has paid to the  Corporation  the
amount  of  any  such  tax,  or has  established,  to  the  satisfaction  of the
Corporation, that such tax has been, or will be, paid.

     f. Sufficient  Reserves of Stock. The Corporation shall at all times use it
s best efforts to reserve and keep available, out of its authorized but unissued
Common  Stock or  treasury  shares,  solely  for the  purpose of  effecting  the
conversion of the Series A Preferred,  the full number of shares of Common Stock
deliverable  upon the  conversion  of all Series A  Preferred  from time to time
outstanding.

     g. Valid  Issue for  Conversion.  All shares of Common  Stock  which may be
issued upon conversion of the shares of Series A Preferred shall,  upon issuance
by the Corporation,  be validly issued, fully paid, non-assessable and free from
all taxes, liens and charges with respect to their issuance.

     h.  Listing  of  Common  Stock;   Registration   under  Exchange  Act.  The
Corporation  shall use its best  efforts to  maintain  the listing of the Common
Stock on the OTC Electronic  Bulletin Board or such other  quotation  service or
exchange on which the Common Stock may be listed,  and shall not take any action
at any time while  Series A Preferred is  outstanding  which would result in the
delisting of the Common Stock from any quotation  service or exchange upon which
the Common Stock may be listed.  The Corporation shall file all reports required
to be filed by it with the SEC pursuant to the  Securities  Exchange Act of 1934
(the "1934 Act")  and/or the  Securities  Exchange Act of 1933 (the "1933 Act"),
and

                                      -10-
<PAGE>
shall not take any action which would result in the deregistration of the Common
Stock under Section 12(g) of the 1934 Act.

6.       ADJUSTMENT OF CONVERSION PRICE

         a.  Adjustment.  The  Series  A  Conversion  Price  or  Minimum  Series
Conversion  Price in effect at any time shall be  adjusted  from time to time as
provided in this Section 6.

         b. No Adjustment for Certain Grants,  Sales, or Issuances.  Anything in
these Articles of Incorporation to the contrary notwithstanding, the Corporation
shall not be required to make any adjustment of the Series A Conversion Price or
Minimum Series A Conversion  Price, as the case may be, in the case of the grant
of options or other  rights to  purchase,  or the sale of, or the  issuance  of,
shares of Common Stock or  obligations  or  securities  convertible  into Common
Stock of the Corporation:

                 (1) to its  officers,  employees,  directors,  and  consultants
pursuant to the  Corporation's  1992 Stock Option Plan or otherwise,  so long as
any such grants,  sales or issuances  do not exceed in the  aggregate  3,500,000
shares of Common Stock or  obligations  or  securities  convertible  into Common
Stock;

                 (2) upon the  exercise of warrants  to  purchase  Common  Stock
which  are  outstanding  as of the  initial  date of the  Corporation's  Private
Offering Memorandum by which the Debentures  convertible into Series A Preferred
were offered to investors; and

                 (3)  upon the  issuance  of any  shares  of  Common  Stock as a
dividend on, or in conversion of, any shares of the Series A Preferred.

         c. Stock  Splits,  Stock  Dividends,  Stock  Combinations.  In case the
Corporation shall at any time subdivide the outstanding  shares of Common Stock,
issue a stock dividend on the outstanding Common Stock,  combine the outstanding
shares of Common Stock or reclassify the outstanding shares of Common Stock into
securities of a different class, the Series A Conversion Price and/or the number
of shares of Common Stock and/or the type of securities issuable upon conversion
of the  Series A  Preferred  in effect  immediately  prior to such  subdivision,
dividend  or  combination  shall be  equitably  adjusted to account for any such
transaction.  The Board of Directors of the Corporation  shall determine in good
faith any such adjustments and its good faith determination, absent a showing of
fraud, shall be binding and conclusive.  Notice shall be provided to all holders
of Series A  Preferred  advising  of any  adjustments  to the  conversion  terms
applicable to the Series A Preferred as soon as  practicable  following the date
of any such adjustment.

         d. Adjustment  Formulas for Certain Issuances.  Should the Corporation,
at some point after the first  issuance of the Series A Preferred and before the
lapse of the Minimum  Series A Conversion  price,  issue or sell Common Stock, a
right or option to purchase  Common  Stock,  or shares of stock or an obligation
convertible into Common Stock for a

                                      -11-
<PAGE>
certain  consideration  receivable by the Corporation per share  ("Consideration
Receivable")  (with  the  product  of the  number  of  such  shares  times  such
Consideration Receivable being the "Aggregate  Consideration  Receivable") which
is less than the Minimum Series A Conversion Price in effect at the time of such
issuance,  then the Minimum  Series A  Conversion  Price shall  immediately  and
automatically  be adjusted as  determined  to the nearest cent by the  following
formula:

  Where    z =       new Minimum Series A Conversion Price;

                     x =     current Minimum Series A Conversion Price;

                     y =     the Aggregate Consideration Receivable on such
                             issuance, sale, etc.;

                     a =     number of shares of Common Stock outstanding just

                             to which all  holders of Options (as
                             defined   in   6(d)(1)   below)  are
                             entitled   to   subscribe   for,  or
                             purchase  immediately prior to, such
                             issuance, sale, etc.;

                     c       = number of  shares of Common  Stock
                             issuable    to   all    holders   of
                             Convertible  Securities  (as defined
                             in 6(d)(2) below), immediately prior
                             to such issuance,  sale, etc. (using
                             the Series A  Conversion  Price then
                             in effect); and

                     d       = number of  shares of Common  Stock
                             to be issued, or deemed to be issued

                             and immediately after such issuance,

provided,  however,  that the  Minimum  Series A  Conversion  Price shall not be
adjusted in the case of an equity  financing of the Corporation  made to holders
of Series A Preferred at a price per share which is less than the Minimum Series
A Conversion  Price to the extent any such holder (together with its affiliates,
if any)  does not  purchase  securities  of the  Corporation  in such  financing
sufficient to retain its or their total pro rata  ownership of the  Corporation,
with such  ownership  being  calculated  immediately  after the  closing of such
financing as if all  securities of the  Corporation  other than its  outstanding
Common Stock were  converted or exercised,  as  appropriate,  into shares of the
Corporation's Common Stock.

                 For  purposes  of this  Subsection  6(d)  only,  the  following
provisions shall apply:

                                      -12-
<PAGE>
                 (1) Options or Warrants. In case of the issuance or sale by the
Corporation  in any manner of any options  for the  purchase of shares of Common
Stock or of any rights to  subscribe  for or to purchase  shares of Common Stock
("Options"),  all shares of Common Stock which the holders of such Options shall
be  entitled to  subscribe  for or purchase  pursuant to such  Options  shall be
deemed to be issued or sold as of the date of the offering of such rights or the
granting of such Options.

                 (2) Convertible Securities. In the case of the issuance or sale
by the Corporation in any manner of any obligations or of any shares of stock of
the Corporation  that shall be convertible into or exchangeable for Common Stock
("Convertible  Securities"),  all  shares  of  Common  Stock  issuable  upon the
conversion or exchange of such  obligations  or shares shall be deemed issued as
of the date such obligations or shares are issued.

                 (3) Cash  Consideration  for  Common  Stock.  In the case of an
issue or sale for cash of shares of Common Stock, the  Consideration  Receivable
by the  Corporation  therefor  shall  be the  amount  of cash  received,  before
deducting any commissions or expenses paid by the Corporation.

                 (4) Non-Cash Consideration for Common Stock. In the case of the
issuance or sale  (otherwise  than upon conversion or exchange of obligations or
shares  of  stock  of  the   Corporation)  of  shares  of  Common  Stock  for  a
consideration  other than cash or a  consideration  partly other than cash,  the
amount of the  consideration  other than cash  receivable by the Corporation for
such shares shall be deemed to be the value of such  consideration as determined
in good faith by the Board of Directors.

              (5)Consideration Receivable for Options or Convertible Securities.

          (a)  The  amount  of the  Aggregate  Consideration  Receivable  by the
     Corporation  upon the issuance of any Options referred to in Subsection (1)
     above shall be the minimum  aggregate  consideration  named in such Options
     for the shares of Common Stock covered thereby, plus the consideration,  if
     any, received by the Corporation for such Options.

          (b) The amount of Consideration Receivable by the Corporation upon the
     issuance of any obligations or shares which are convertible or exchangeable
     as described in Subsection  (2) above as Convertible  Securities,  shall be
     the amount of  consideration  received by the Corporation upon the issuance
     of such obligations or shares, plus the minimum aggregate consideration, if
     any, other than such  obligations or shares,  receivable by the Corporation
     upon such conversion or exchange, except in adjustment of dividends.

          (c)  The   amount  of   Aggregate   Consideration   Receivable   under
     Subparagraphs   6(d)(5)a   and   6(d)(5)b   and  the  amount  of  Aggregate
     Consideration   Receivable  upon  the  exercise  of  Options  or  upon  the
     conversion or exchange of convertible securities


                                      -13-
<PAGE>
     under  this  Paragraph  6(d)(5),  shall be  determined  in the same  manner
     provided  in  Paragraphs  6(d)(3)  and  6(d)(4)  above with  respect to the
     Aggregate Consideration Receivable by the Corporation as in the case of the
     issuance of additional  shares of Common Stock.  But if such obligations or
     shares of stock so convertible or  exchangeable  are issued in satisfaction
     of any dividend upon any stock of the Corporation  other than Common Stock,
     the amount of the consideration received upon the original issuance of such
     obligations  or shares of stock shall be the value of such  obligations  or
     shares of stock, as of the date of the adoption of the resolution declaring
     the  dividend,  as determined in good faith by the Board of Directors at or
     as of that date.

                 (6)  Other  Particulars   Concerning  Options  and  Convertible
Securities.  In the event that the Minimum  Series A  Conversion  Price shall be
adjusted with respect to the issuance of Options or  Convertible  Securities (as
defined in Paragraphs 6(d)(1) and 6(d)(2)), the following provisions apply:

          (a) No further  adjustment  in the Minimum  Series A Conversion  Price
     shall be made upon the subsequent issue of Convertible Securities or shares
     of Common  Stock when those  Options  are  exercised  or those  Convertible
     Securities are converted.

          (b) Such Options or Convertible Securities may by their terms provide,
     with  the  passage  of  time  or   otherwise,   for  any  decrease  in  the
     consideration  payable to the  Corporation,  or  increase  in the number of
     shares of  Common  Stock  issuable,  upon  their  exercise,  conversion  or
     exchange.  In such a case, the Minimum  Series A Conversion  Price computed
     upon the original issue thereof, and any subsequent adjustments shall, upon
     any such increase or decrease becoming effective,  be recomputed to reflect
     such increase or decrease insofar as it affects those Options or the rights
     of conversion or exchange under those Convertible Securities.

          (c)  Upon  the  expiration  of  any  such  Options  or any  rights  of
     conversion  under such  Convertible  Securities  which  shall not have been
     exercised, the Minimum Series A Conversion Price computed upon the original
     issue thereof, and any subsequent  adjustments shall, upon such expiration,
     be recomputed as if:

                                    i) in the case of Convertible  Securities or
                          Options for Common Stock,  the only additional  shares
                          of Common Stock issued were the shares of Common Stock
                          actually  issued upon the  exercise of such Options or
                          the conversion of such Convertible Securities; and the
                          Aggregate    Consideration    Receivable    was    the
                          consideration actually received by the Corporation for
                          the issue of such  Convertible  Securities  which were
                          actually converted, and

                                    ii) in the case of Options  for  Convertible
                          Securities,  only the Convertible  Securities actually
                          issued upon the exercise thereof were


                                                       -14-
<PAGE>
                          issued at the time of issue of such  Options;  and the
                          Aggregate Consideration  Receivable for the additional
                          shares or Common Stock deemed to have been then issued
                          was  the   consideration   actually  received  by  the
                          Corporation  for the  issue  of all such  Options  for
                          Convertible Securities, whether or not exercised, plus
                          the consideration  deemed to have been received by the
                          Corporation (determined pursuant to Paragraph 6(d)(5))
                          upon the issue of the Convertible Securities when such
                          Options were actually exercised.

                  (d) No  readjustment  pursuant  to  Subparagraph  6(d)(6)b  or
Subparagraph  6(d)(6)c  shall have the effect of increasing the Minimum Series A
Conversion  Price  by an  amount  greater  than  the  amount  of the  adjustment
originally made when the Options or Convertible Securities were issued.

                  (e) In the case of any Options which expire by their terms not
more than thirty (30) days after the date of issue or sooner,  no  adjustment of
the Minimum  Series A  Conversion  Price shall be made until the  expiration  or
exercise of all such Options.

                  (f)      Waiver of Adjustment.

               i) In the event that holders of a majority of the then  currently
          outstanding  shares of the Series A Preferred  shall consent to limit,
          or waive in its entirety,  any  anti-dilution  adjustment to which the
          holders of such series would  otherwise be entitled  under  Subsection
          6(d)  hereof,  the  Corporation  shall  not be  required  to make  any
          adjustment   whatsoever  with  respect  to  any  shares  of  Series  A
          Preferred,  or to make any  adjustment  with  respect to any shares of
          Series A Preferred in excess of any limit set by such consent.

               ii) Moreover, any holder of Series A Preferred shall be permitted
          to waive in whole or in part, currently or prospectively,  by contract
          or any other writing,  any anti-dilution  adjustment to which he or it
          would otherwise be entitled pursuant to the provisions of this Section
          6.

         e.  No   Adjustment   of  Series  A  Conversion   Price  Under  Certain
Circumstances.  Following the lapse of the Minimum Series A Conversion Price, no
adjustment  to the  Series A  Conversion  Price  shall be made for  transactions
described in Subsection 6(d).

7.       REORGANIZATION, RECLASSIFICATION, AND SALE OF ASSETS.

         If any capital  reorganization or reclassification of the capital stock
of the Corporation,  including any such  reorganization or  reclassification  in
connection with any merger,  consolidation,  or transfer of substantially all of
the assets of the Corporation,  shall not be deemed to be a Liquidation pursuant
to Section 4 hereof,  and if it shall be effected in such a way that  holders of
Common Stock shall be entitled to receive stock, securities, or assets


                                      -15-
<PAGE>
with respect to or in exchange for Common Stock,  then the following shall be an
express condition of such reorganization or reclassification.

         a. Lawful and adequate provisions in a form satisfactory to the holders
of a majority of the Series A  Preferred  shall be made  whereby  each holder of
shares of Series A Preferred shall  thereafter  have the right to receive,  upon
the terms and  conditions  specified  herein and in lieu of the shares of Common
Stock of the Corporation  immediately theretofore receivable upon the conversion
of such shares of the Series A Preferred,  such shares of stock, securities,  or
assets as may be issued or payable  with  respect to or in exchange for a number
of outstanding shares of such Common Stock equal to the number of shares of such
stock  immediately   theretofore  so  receivable  had  such   reorganization  or
reclassification not taken place.

         b. Moreover, in any such case, appropriate provision shall be made with
respect to the rights and interests of each such holder of Series A Preferred to
the end that the provisions hereof (including without limitation  provisions for
adjustments  of the Minimum  Series A  Conversion  Price)  shall  thereafter  be
applicable, as nearly as may be, in relation to any shares of stock, securities,
or assets thereafter deliverable upon the exercise of such conversion rights. In
the event of a merger or consolidation of the Corporation as a result of which a
greater or lesser number of shares of Common Stock of the surviving  Corporation
are  issuable  to  holders of the Common  Stock of the  Corporation  outstanding
immediately  prior  to such  merger  or  consolidation,  the  Minimum  Series  A
Conversion  Price and terms of  conversion in effect  immediately  prior to such
merger or  consolidation  shall be adjusted  in the same manner as though  there
were a subdivision or combination of the  outstanding  shares of Common Stock of
the Corporation.

         c.  The   Corporation   shall  not  effect  any  such   reorganization,
reclassification,   consolidation,   merger,  or  sale  unless,   prior  to  the
consummation thereof: (i) the Corporation shall have obtained the consent of the
holders of a majority of the Series A Preferred then  outstanding,  and (ii) the
successor  corporation  (if  other  than the  Corporation)  resulting  from such
consolidation or merger, or the corporation purchasing such assets, shall assume
by written  instrument,  in a form  satisfactory to the holders of a majority of
the Series A Preferred then outstanding the obligation to deliver to such holder
such shares of stock, securities, or assets as, in accordance with the foregoing
provisions,  such holder may be entitled to  receive.  Such  written  instrument
shall be  promptly  mailed  or  delivered  to each  holder of shares of Series A
Preferred  at the last  address  of such  holder  appearing  on the books of the
Corporation.

8.       REDEMPTION

         a.       Early Redemption by the Corporation.

                  (1) The Series A Preferred may be redeemed in whole or in part
at the election of the  Corporation  upon not less than 30 nor more than 60 days
prior written notice


                                      -16-
<PAGE>
by mail,  at any time up to 270 days  following the Initial  Closing  Date,  if,
during such 270 day period,  the closing bid price for the Common  Stock for any
20 trading  days within any 30  consecutive  trading day period as quoted on the
OTC Electronic Bulletin Board (or such other quotation service as is quoting bid
and asked prices for the Common Stock),  or the closing bid price for the Common
Stock as reported by the NASDAQ Stock Market or any other national exchange upon
which the  Common  Stock is listed  for  trading  which  has  closing  bid price
reporting,  is less  than the  Minimum  Conversion  Price.  Notwithstanding  the
foregoing,  if the 20 day period  during  which the price of the Common Stock is
less than the Minimum  Conversion  Price falls  totally with the last 60 days of
the 270 days following the Initial  Closing Date, the  Corporation  shall have a
full 60 days from the end of such 270 day period to exercise  its right of early
redemption.

                  (2)  To  redeem  the  Series  A  Preferred  pursuant  to  this
Subsection  8(a),  the  Corporation  shall  pay the  holders  of  Series A being
redeemed  118% of the Stated  Value of the Series A  Preferred  being  redeemed,
together with accrued but unpaid  interest owing to the date of  redemption,  in
cash. Any Series A Preferred which is redeemed in part only shall be redeemed in
principal amounts of $1,000 or whole multiples of $1,000.

         b. Other Redemption Rights of the Corporation. The Corporation shall be
entitled to redeem any shares of Series A  Preferred  remaining  outstanding  36
months  after the  Initial  Closing  Date by paying to the  holders  thereof the
Stated  Value of the  shares  of Series A  Preferred  being  redeemed,  plus any
accrued and unpaid dividends on such shares of Series A Preferred to the date of
redemption,  upon no less  than 30 and not  more  than 60 days  advance  written
notice of the date fixed for such redemption. The Corporation shall pay cash for
all amounts due on such redemption.

         c.  Redemption  Notices.  The  notice of  redemption  to be sent to all
holder of Series A  Preferred  (the  "Redemption  Notice")  shall state the date
fixed for redemption (the "Redemption  Date"),  the paying agent with whom funds
sufficient to make the redemption have been deposited,  and the number of shares
to be redeemed  from each such holder,  together  with the amount of any accrued
and  unpaid  dividends  to be  paid  as of  the  Redemption  Date.  Any  partial
redemption shall be pro rata as between the holders of all Series A Preferred.

         d.   Right  to  Convert   Series  A   Preferred   Pending   Redemption.
Notwithstanding  the above,  any holder of Series A  Preferred  may  convert the
shares of  Series A  Preferred  so called  for  redemption,  plus all  dividends
accrued and unpaid on such shares to the Redemption  Date, into shares of Common
Stock, at any time following the giving of the Notice of Redemption and prior to
the Redemption Date.

9.       NO IMPAIRMENT

                  The  Corporation  shall not, by  amendment  of its Articles of
Incorporation or through any reorganization,  transfer of assets, consolidation,
merger, dissolution, issue, or

                                      -17-
<PAGE>
sale of securities  or any other  voluntary  action,  avoid or seek to avoid the
observance of  performance of any of the terms in this Article to be observed or
performed by the Corporation.  The Corporation  shall at all times in good faith
assist in the carrying out of all the provisions of Sections 5, 6 and 7 hereof.

10.      CERTIFICATE AS TO ADJUSTMENTS

         a. Upon the  occurrence  of each  adjustment of the Series A Conversion
Price  pursuant  to  Section  6, or any  transaction  requiring  a change in the
conversion  terms  applicable to the Series A Preferred as required by any other
provision of this  Article,  the  Corporation,  at its expense,  shall  promptly
compute any such  adjustment  and prepare and furnish to each holder of Series A
Preferred a certificate setting forth such adjustment and/or any other change in
the conversion terms applicable to the Series A Preferred, showing in detail the
facts upon which such adjustment and/or change is based; and

         b. Upon the  written  request  at any time from any  holder of Series A
Preferred  the  Corporation  shall  furnish  to such  holder a like  certificate
setting  forth (i) such  adjustment,  (ii) the Series A Conversion  Price at the
time in effect,  and (iii) the number of shares of Common  Stock and the amount,
if any, of other property which at the time would be received upon conversion of
Series A Preferred.

11.      NOTICE OF RECORD DATES

         In the event:

         a.  that the  Corporation  shall  take a record of the  holders  of its
         Common Stock for the purpose of entitling  them to vote upon any matter
         to be  submitted  to  shareholders  of  Common  Stock or other  votable
         securities of the Corporation;

         b.  that the  Corporation  shall  take a record of the  holders  of its

         rights;

         d. of any capital  reorganization of the Corporation,  reclassification

of record of Series A Preferred at such holder's address  appearing on the books
of the  Corporation  or,  in the  case  of  notice  to the  Corporation,  to its
Principal Office, sent to the attention: "Chief Financial Officer."

13.      VOTING

or the law of the State of Colorado.

14.      AMENDMENTS AND CHANGES

         As  long  as any  of  the  Series  A  Preferred  shall  be  issued  and
outstanding,  the Corporation  shall not take any action without first obtaining
the approval (by vote or written consent,  as provided by law) of the holders of
a majority  of the Series A Preferred  then  outstanding,  if such action  would

"Holder").

                                    RECITALS


         A. The Holder and the Company are parties to the Subscription Agreement
of  even  date  herewith  (the  "Agreement")  whereby  Holder  has  been  issued
$________________ of Debentures in exchange for cash paid to the Company in like
amount.

         B. The  Debenture  automatically  converts into shares of the Company's
Series A Cumulative  Convertible  Preferred Stock (the "Preferred Stock") at the
rate of one share of Preferred  Stock per $1.00 of Debenture at such time as the
Preferred Stock has been legally authorized by the Company.

         C. Upon  satisfaction  of certain  conditions:  the  Debenture  and the
Preferred  Stock into which it may  convert are  convertible  into shares of the
Company's no par value Common Stock (the  "Conversion  Stock");  interest due on
the Debenture and dividends payable on the Preferred Stock are payable in shares
of Common Stock (the "I/D  Stock"),  all pursuant to the formulas  stated in the
Debenture and Designation of Preferred Stock, respectively.

         D. The  Holder is willing  to have all of its  rights  with  respect to
registration  of their  Registrable  Securities  (as  defined  below)  under the
Securities Act of 1933 governed by this Agreement.


                                      TERMS

         NOW, THEREFORE,  in consideration of the promises and covenants and the
mutual obligations of the parties hereto, as stated herein, the parties agree as
follows:

1.       REGISTRATION UNDER THE SECURITIES ACT OF 1933.

or any other federal agency at the time administering the Securities Act.

           "Holder" shall mean the holder of outstanding Registrable Securities.

                  The terms "register",  "registered," and "registration"  refer
to a registration  effected by preparing and filing a registration  statement in

(a) possession by the Company of material information not ripe for disclosure in
a registration  statement,  which shall be evidenced by a determination  made in
good faith by the Board of  Directors  of the Company  that  disclosure  of such
information in the registration  statement would be seriously detrimental to the
business and affairs of the Company;  (b) any material engagement or activity of
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 inclusion of such information.

                  "Registrable  Securities"  means (i) the Conversion Stock (ii)
the I/D Stock; and (iii) any other securities  issued with respect to any of the
above   securities   by  way  of  dividends,   stock-splits,   recapitalization,
adjustments or the like.  Registrable Securities do not include any of the above
securities which have been registered pursuant to a registration statement under
the Act and sold pursuant  thereto or which have otherwise  become  eligible for
sale.

                  "Registration  Expenses"  shall mean all expenses  incurred by
the  Company  in  complying  with  Section  1.6  below,  including,  by  way  of
illustration  only and without  limitation,  all  registration  and filing fees,
printing   expenses,   fees  and  disbursements  of  counsel  for  the  Company,
underwriting  expenses not included in Selling Expenses,  and the expense of any
audits or  financial  statement  reviews  incident  to or  required  by any such
registration  (including the expense of any cold comfort letters),  and Blue Sky
fees and expenses (but excluding the  compensation  of regular  employees of the
Company, which shall be paid in any event by the Company).

                  "Restricted  Securities"  shall  mean  the  securities  of the
Company  required  to bear the legend  substantially  the same as the legend set
forth in Section 1.2(D) of this Agreement.

                                       -2-
<PAGE>
             "Securities Act" shall mean the Securities Act of 1933, as amended.

                  "Selling  Expenses" shall mean the underwriting  discounts and
selling  commissions  applicable to the sale of  Registrable  Securities and any
fees of any counsel or other advisors retained by or to represent any Holder.

     Section  1.2  Proposed  Transfers.   The  Holder,  by  entering  into  this
Agreement, agrees to comply in all respects with the following provisions:

                  (A)  Prior  to  any  proposed   transfer  of  any  Registrable
Securities (other than under circumstances  described in Section 1.3 and Section
1.4  below),  Holder  shall  give  written  notice to the  Company  of  Holder's
intention  to effect the  transfer,  together  with a detailed  statement of the
circumstances  surrounding the proposed transfer;  provided,  however,  that the
Holder need not provide such notice with respect to  Registrable  Securities for
which the Company has previously issued unlegended certificates.

                  (B) Except with respect to transactions not involving a change
in  beneficial  ownership,  such notice shall,  if  reasonably  requested by the
Company,  also be accompanied by a written opinion of legal counsel (which shall
be  reasonably  satisfactory  to the Company and its  counsel)  stating that the
proposed  transfer  of  the  Registrable  Securities  may  be  effected  without
registration  under the Securities Act and without Blue Sky  qualification,  and
which opinion may be "reasoned"  and/or based upon (i) no action  letters issued
by the Commission which are based on similar facts or circumstances  and/or (ii)
telephone  conversations  or  written  correspondence  with  the  staff  of  the
Commission.

                  (C) Having satisfied Subsection 1.2(B) above, the Holder shall
be entitled to transfer the Registrable  Securities in accordance with the terms
of the notice delivered by the Holder to the Company.

                  (D) Each certificate  evidencing  Registrable Securities shall
(unless  otherwise  permitted by the provisions of this Agreement) be stamped or
otherwise  imprinted  with a  legend  in  substantially  the  following  form in
addition to any legend acquired under applicable state securities laws:

         THESE SHARES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
         AS AMENDED,  OR ANY  APPLICABLE  STATE  SECURITIES  LAWS AND MAY NOT BE
         SOLD,  OFFERED FOR SALE,  TRANSFERRED,  PLEDGED OR  HYPOTHECATED IN THE
         ABSENCE OF AN EFFECTIVE  REGISTRATION  STATEMENT  AS TO THE  SECURITIES
         UNDER  SAID ACT AND  SUCH  LAWS OR AN  OPINION  OF  COUNSEL  REASONABLY
         SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.


                                       -3-
<PAGE>
The Company shall remove such  restrictive  legend upon the request of Holder if
(1) the Company has received an opinion of counsel who is reasonably  acceptable
to it and its  counsel to the  effect  that  registration  of any and all future
transfers  is not  required,  (2) an  appropriate  registration  statement  with
respect to such  Registrable  Securities  has been filed by the Company with the
Commission  and  declared   effective  by  the  Commission  and  the  shares  of
Registrable  Securities to be sold under the  registration  statement  have been
sold  thereunder  and in compliance  with the  applicable  plan of  distribution
contained therein and any  qualifications  required under any Blue Sky Laws, (3)
such transfer shall be made in compliance  with the  requirements of Rule 144 or
its successor,  or (4) Holder has met the  requirements of  subparagraph  (k) of
Rule 144 or its successor.  Under any of these circumstances,  the Company shall
cause new  certificates  without the above  legend to be issued  promptly to the
Holder  or  the  Holder's   designee  in  exchange  for   outstanding   legended
certificates.

         Section 1.3       Company Registration.

                  (A) Notice and  Piggyback  Rights.  If at any time the Company
shall decide to register any of its securities, the Company will:

          (1) promptly give to Holder written notice of the registration  (which
     shall include a list of the  jurisdictions  in which the Company intends to
     attempt to qualify such securities under the applicable Blue Sky laws); and

          (2)  include  in  such   registration   (and  any  related   Blue  Sky
     qualification or other compliance  reasonably  requested by Holder in order
     to  sell  such  securities),  and in any  underwriting  involved,  all  the
     Registrable  Securities specified in a written request, made within 30 days
     after  receipt of such  written  notice  from the  Company,  by the Holder,
     except as set forth in Subsection 1.3(B) below.

                  The provisions of this  Subsection  1.3(A) do not apply to any
of the following:  (i) a registration on any  registration  form which would not
permit  secondary sales by Holder,  (ii) a registration  which relates solely to
employee  benefit  plans,  or (iii) a  registration  which  relates  solely to a
Commission Rule 145 transaction.

                  (B)  Underwriting;  Limits.  If the  registration of which the
Company  gives  notice  is  for  a  registered  public  offering   involving  an
underwriting,  the  Company  shall so advise the Holder as a part of the written
notice given pursuant to Subsection 1.3(A). If Holder proposes to distribute its
Registrable  Securities  through  such  underwriting,  it  shall  enter  into an
underwriting  agreement in customary form with the underwriters  selected by the
Company.  Notwithstanding  any  other  provision  of this  Section  1.3,  if the
underwriter determines that marketing factors require a limitation of the amount
of securities to be registered,  the Company may exclude from such  registration
any Registrable  Securities  requested to be included.  If Holder disapproves of
the  terms of any such  underwriting,  it may  elect to  withdraw  therefrom  by
written notice to the Company and the underwriter

                                       -4-
<PAGE>
within  five  (5)  days  after  receipt  of such  notice,  and  any  Registrable
Securities  excluded or withdrawn from such underwriting shall be withdrawn from
registration.

                  (C) Waiver.  The Holder's rights under this Section 1.3 may be
waived as to any particular offering by the Holder.

         Section 1.4       Mandatory Registration upon Issuance of Debentures

                  (A) Mechanics. On or after the initial date of issuance of the
Debentures to the Holder,  the Company shall use its best efforts to prepare and
file a shelf registration statement and other qualifications or compliances with
respect to all Registrable  Securities  requested to be included  therein by the
Holder.  Holder  shall only be  entitled to have  included in such  registration
statement that number of shares which Holder  reasonably  expects to sell within
sixteen  months of June 30, 1998.  Holder shall advise the Company of the number
of shares  intended to be sold during such period and shall  further  advise the
Company as to those specific jurisdictions in which Holder reasonably expects to
offer the Registrable  Securities for sale during such period.  Holder shall not
be entitled to fulfill the  requirements  of this  designation  by stating  "all
states" or by listing  each and every state in the United  States.  Holder shall
further  advise the  Company  of any plan of  distribution  for the  Registrable
Securities  and  shall  enter  such  further  agreements  as the  Company  shall
reasonably request setting forth additional terms applicable to the distribution
of Registrable Securities.

                  The Company will:

          (1) Use its diligent best efforts to file as soon as practicable,  but
     in any event within ninety days (90) days after the initial  closing of the
     offering by which the Debentures  were first sold, all such  registrations,
     qualifications  and  compliances  as  may  be so  requested  and  as  would
     facilitate  the  sale  and  distribution  of all or  such  portion  of such
     Holder's Registrable Securities as are specified in the request.

          (2)  Use its  diligent  best  efforts  to  prepare,  file  and  obtain
     effectiveness  of the  registration  statement under this Section 1.4 on no
     more than one (1)  occasion,  excluding  offerings  by Holder  pursuant  to
     Section 1.3 above.  If any  proceeds of the  offering  are  received by the
     Company, the offering will be deemed to be pursuant to Section 1.3 above.

          (3) The Company  shall use its best  efforts to keep the  registration
     statement effective  continuously for no less than sixteen (16) months from
     June 30, 1998,  subject to the right of the Company to suspend  sales under
     the  registration  statement  during such period as described in Subsection
     1.6(E).  Any suspension of sales during such period of effectiveness  shall
     not toll the sixteen  month  period,  unless the Company  shall suspend the
     period  during  which sales may be made for greater than a total of 90 days
     in the aggregate during such period.  In that case, the period during which
     the registration statement shall be


                                       -5-
<PAGE>
maintained as effective shall be extended for a like number of days in excess of
such 90 days during which suspension(s) of sales was required by the Company. By
way of example,  if the Company  suspends sales of Registrable  Securities for a
total of 120 days during the sixteen  month  period,  then the Company  shall be
obligated to extend the period for which a  registration  statement is effective
for 30 additional days.

                  (B)  Exceptions.  The Company shall not be obligated to effect
any registration,  qualification, or compliance requested by Holder with respect
to a  proposed  distribution  of  Registrable  Securities  by Holder  under this
Section 1.4:

          (1) in any  particular  jurisdiction  in which  the  Company  would be
     required  to execute a general  consent to service of process in  effecting
     such registration,  qualification or compliance or where such registration,
     qualification or compliance  would be legally  unattainable or unreasonably
     expensive or onerous for the  Company,  in light of all  circumstances  and
     other  avenues  available  to  the  Holder  for  disposing  of  Registrable
     Securities; or

          (2) if the Company has effected one (1) such registration  pursuant to
     this  Section  1.4 and such  registration  has been  declared  and  ordered
     effective.

                  If the Company shall furnish to Holder a certificate signed by
the  President  of the Company  stating  that there  exist a Potential  Material
Event,  then  the  Company's  obligation  to use  its  best  efforts  to  file a
registration  statement  under this  Section 1.4 shall be deferred  for a period
during which such Material  Potential  Event  exists,  provided that this period
will not exceed ninety (90) days after the expiration of the initial ninety (90)
days within which to file such registration statement, and provided further that
the Company shall not defer its obligations in this manner more than once in any
twelve-month  period.  Nothing  done by the Company  pursuant to this  paragraph
shall in any way prevent application of the penalty provisions  contained in the
Debentures  and/or the  Designation of Preferred Stock that effect a decrease in
the conversion  price  applicable to conversions of such instruments into Common
Stock should the  effectiveness of the registration  statement be delayed beyond
150 days  from the date of the  initial  closing  of the  offering  by which the
Debentures were first sold.

                  (C)  Underwriting.  If the Holder  intends to  distribute  the
Registrable  Securities  covered by its request by means of an underwriting,  it
shall so advise the  Company as a part of its request  made  pursuant to Section
1.4.

          (1) The Holder shall negotiate with an underwriter  selected by Holder
     and reasonably  approved by the Company with regard to the  underwriting of
     the requested registration.

          (2) The right of Holder to include  its  Registrable  Securities  in a
     registration pursuant to Section 1.4 shall be conditioned upon the Holder's
     participation in

                                       -6-
<PAGE>
     such underwriting on the terms and conditions of such underwriting and upon
     the  inclusion  of  the  Holder's  Registrable   Securities  sought  to  be
     registered in the underwriting.

          (3)  The  Company   shall   (together   with  Holder)  enter  into  an
     underwriting   agreement  in  customary   form  with  the   underwriter  or
     underwriters selected for the underwriting by the Holder.

          (4)  Notwithstanding  any other  provision of this Section l.4, if the
     underwriter  advises the Holder in writing that marketing factors require a
     limitation  of the number of shares to be  underwritten,  the Company  will
     then  include in such  registration,  prior to the  inclusion  of any other
     securities  which are not Registrable  Securities,  the number of shares of
     Registrable Securities that the underwriter believes may be included in the
     registration.  A registration  will not count as the  registration  request
     permitted  under this Section 1.4 unless the Holder is able to register and
     sell at least 75% of the Registrable Securities requested to be included in
     such registration.

                  (D) Holder  understands and agrees that other  securityholders
of the  Company  may have  registration  rights  that will be  activated  by the
Company's  obligations  to register  Registrable  Securities  hereunder.  Holder
agrees  that such  rights  may be  honored  by the  Company  and that such other
securities may be included in the registration(s) filed pursuant to Sections 1.3
and 1.4 of this  Agreement.  The  Company  agrees  that it shall  not  grant any
additional  rights to any person which would  entitle such person to have shares
of  the  Company's  Common  Stock  (or  other  securities   exercisable  for  or
convertible  into Common Stock)  included in any  registration  statement  filed
hereunder.

                  (E) Holder agrees to advise the Company in writing of each and
every  sale of  Registrable  Securities  made by Holder  under any  registration
statement within 10 days following the date of each sale. Holder understands and
agrees that any Registrable  Securities  remaining  unsold by Holder at the time
the Registration Statement expires will be deregistered and cannot thereafter be
sold absent reregistration or compliance with Section 1.2 of this Agreement.

         Section 1.5       Expenses of Registration.

                  (A) Registration  Expenses. All Registration Expenses incurred
in connection with  registration,  qualification or compliance under Section 1.3
and Section 1.4 shall be borne by the  Company;  provided  that with  respect to
securities being registered  pursuant to Section 1.3, Holder agrees that it will
pay all Blue Sky fees associated with the registration of Registrable Securities
in those states in which the Company is not otherwise  registering or qualifying
shares of its stock for sale in such registration.

                  (B)  Selling  Expenses.   All  Selling  Expenses  incurred  in
connection with these transactions shall be borne by the Holder.


                                       -7-
<PAGE>
                  (C) Legal  Expenses.  Holder shall bear its own  expenses,  if
any, for the fees and  disbursements of counsel or other advisors to such Holder
incurred in connection with these transactions.

                  (D) Ineffective Requested Registration.  The Company shall not
be required to pay any Registration Expenses if the registration  statement does
not  become  effective  as a  result  of  the  withdrawal  of  the  request  for
registration by the Holder pursuant to Subsection  1.4(A),  which withdrawal was
not caused by the  Company's  failure  to comply  with  applicable  registration
requirements  and  regulations.  In such a case,  the  Holder  shall  bear  such
Registration   Expenses  and  such  registration  shall  not  be  counted  as  a
registration  pursuant to  Subsection  1.4(A),  or the Holder will not bear such
expenses and such  registration  shall be counted as a registration  pursuant to
Subsection 1.4(A).

         Section 1.6 Registration Procedures.  In the case of each registration,
qualification or compliance  effected by the Company pursuant to this Agreement,
the Company  will keep Holder  advised in writing as to the  initiation  of each
registration,  qualification and compliance and as to the completion thereof. At
its expense the Company will:

                  (A)  Advise the Holder  within  forty  eight (48) hours of the
effectiveness  with the SEC of any registration  statement which includes shares
eligible for sale by the Holder thereunder.

                  (B)  Keep  such  registration,   qualification  or  compliance
effective  until the Holder has  completed  the  distribution  described  in the
registration statement), but for not more than sixteen months from June 30, 1998
(or  if  the   registration   is   underwritten,   90  days  from  the  date  of
effectiveness).

                  (C) Furnish such number of prospectuses (including preliminary
prospectuses,  sticker  supplements and amendments) and other documents incident
to the registration as Holder from time to time may reasonably request.

                  (D)  At the  time  when  any  registration  statement  becomes
effective,  and at the time when any post-effective amendment becomes effective,
request counsel to furnish to the Holder an opinion of counsel in customary form
and reasonably satisfactory to the Holder.

                  (E)  Notify  Holder,  at any time when a  prospectus  relating
thereto is required to be delivered  under the Securities  Act, of the happening
of any event as a result of which the prospectus  included in such  registration
statement  contains  an untrue  statement  of a material  fact or omits any fact
necessary to make the statements  therein not misleading,  and at the request of
Holder, the Company will prepare a supplement or amendment to such prospectus so
that, as thereafter delivered to the purchasers of such Registrable  Securities,
such prospectus will not contain an untrue  statement of a material fact or omit
to state any fact  necessary  to make the  statements  therein  not  misleading.
Between such time as the

                                       -8-
<PAGE>
Company  notifies a Holder  pursuant  to this  Subsection  and the time any such
supplement or amendment is effective  and  available  for use, the  registration
shall be suspended  and no sales by Holder shall be made of  Registrable  Shares
thereunder during such period.

                  (F) Cause all such Registrable Securities to be listed on each
securities  exchange,   quotation  system  or  other  market  on  which  similar
securities issued by the Company are then listed.

                  (G)  Provide  a  transfer  agent  and  registrar  for all such
Registrable  Securities not later than the effective  date of such  registration
statement.

                  (H)  Obtain  a  cold   comfort   letter  from  the   Company's
independent  public  accountants  in customary form and covering such matters of
the  type  customarily  covered  by  cold  comfort  letters  as the  Holder  may
reasonably request.

                  (I) Furnish an opinion of the counsel representing the Company
for the purposes of such  registration,  in form and substance as is customarily
given to underwriters in an underwritten public offering.

         Section 1.7       Indemnification.

                  (A)      Company's Obligation to Indemnify.

          (1) Generally.  Subject to subparagraph (3) below, with respect to any
     registration,  qualification or compliance which has been effected pursuant
     to this  Agreement,  the  Company  will  indemnify  Holder,  its  officers,
     directors,  and partners  and each person  controlling  Holder,  each legal
     counsel,  and each  underwriter,  against all claims,  losses,  damages and
     liabilities (or actions in respect  thereof) arising out of or based on any
     untrue or alleged untrue statement of, or omission or alleged omission of a
     material fact  contained  in, or required to be stated in any  registration
     statement, including any preliminary or final prospectus, offering circular
     or other  document  incident to any such  registration,  qualification,  or
     compliance.  The Company will further  indemnify  such persons  against any
     violation  or alleged  violation  by the Company of any rule or  regulation
     promulgated under the Securities Act or any applicable state securities law
     in connection with any such registration, qualification or compliance.

          (2)  Reimbursement.  The Company will promptly  reimburse Holder,  and
     each of its officers,  directors,  partners and controlling  persons,  each
     legal  counsel  and each  such  underwriter,  for any  legal  and any other
     expenses reasonably incurred,  as such expenses are incurred, in connection
     with investigating or defending any such claim, loss, damage,  liability or
     action.

          (3) Limitation. The Company will not be liable in any such case to the
     extent that any claim, loss, damage, liability or expense arises out of any
     untrue

                                       -9-
<PAGE>
statement (or alleged untrue  statement) or omission (or alleged  omission) made
in such registration  statement,  including any preliminary or final prospectus,
offering circular or other document, is based upon written information furnished
to the Company by an instrument duly executed by Holder or underwriter and which
is stated to be specifically for use therein.

          (4) Survival of Obligation.  The obligations of the Company under this
     Section 1.7 shall survive the  completions  of the offerings of Registrable
     Securities under the registration statements, and otherwise.

                  (B)      Holder's Obligation to Indemnify.

          (1)  Generally.   Subject  to  subparagraph  (3)  below,  Holder  will
     indemnify the Company, each legal counsel and independent accountant of the
     Company,  each  underwriter of the Company's  securities  covered by such a
     registration statement, and each person who controls the Company within the
     meaning  of the  Securities  Act,  and all of  their  respective  officers,
     directors and partners, against all claims, losses, damages and liabilities
     (or  actions in respect  thereof)  arising out of or based on any untrue or
     alleged untrue  statement of, or omission or alleged omission of a material
     fact contained in, or required to be stated in, any registration statement,
     including any preliminary or final  prospectus,  offering circular or other
     document.

          (2)  Reimbursement.  Furthermore,  Holder will promptly  reimburse the
     Company, underwriters, legal counsel and independent accountants and all of
     their respective officers, directors, partners, and controlling persons for
     any legal or any other  expenses  reasonably  incurred in  connection  with
     investigating  or  defending  any such claim,  loss,  damage,  liability or
     action.

          (3) Limitation. In any case, Holder's obligation under this Subsection
     1.7(B) shall extend only so far as the untrue  statement (or alleged untrue
     statement) or omission (or alleged  omission) is made in such  registration
     statement  (including  any  preliminary  or  final  prospectus),   offering
     circular,  or other document in reliance upon written information furnished
     to the Company by an instrument duly executed by Holder and which is stated
     to be specifically for use therein.

          (4) Survival of Obligation of the Holder.  The  obligations  of Holder
     under this Section 1.7 shall survive the redemption and conversion, if any,
     of the Purchased  Stock,  the  completions  of the offerings of Registrable
     Securities under the registration statements, and otherwise.

                  (C)      Indemnifying Party May Assume Defense.

          (1)  Generally.  Each party  entitled  to  indemnification  under this
     Section  1.7 (the  "Indemnified  Party")  shall  give  notice  to the party
     required to provide

                                      -10-
<PAGE>
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought. Unless in
such Indemnified Party's reasonable judgment a conflict of interest between such
Indemnified and  Indemnifying  Parties may exist with respect to such claim, the
Indemnified  Party shall permit the Indemnifying  Party to assume the defense of
any such claim or any  resulting  litigation.  But counsel for the  Indemnifying
Party,  who shall  conduct  the  defense of such claim or  litigation,  shall be
approved by the  Indemnified  Party (whose  approval shall not  unreasonably  be
withheld),  and the Indemnified Party may participate in such defense at its own
expense.  Failure by the Indemnified  Party to provide such written notice shall
not relieve the  Indemnifying  Party from its obligation under this Section 1.7.
In the event that the Indemnifying Party does not assume the defense of any such
claim or any resulting  litigation within a reasonable period of time, or in the
event disparate  interests of the Indemnified and  Indemnifying  Parties require
the Indemnified Party to seek separate counsel, the Indemnified Party may assume
the defense with counsel of its choice,  and the Indemnifying Party will pay the
reasonable  expense of such counsel;  provided,  however,  that the Indemnifying
Party will be required to assume the expense of only one single  counsel for all
Indemnified Parties in connection with any given claim or litigation.

          (2) Settlement Approval,  Release Required.  No Indemnifying Party, in
     the defense of any such claim or litigation, shall, except with the consent
     of each Indemnified  Party,  consent to entry of any judgment or enter into
     any settlement which does not include as an  unconditional  term the giving
     by the claimant or plaintiff to the Indemnified Party of a release from all
     liability in respect to such claim or litigation.  Furthermore, the failure
     of any  Indemnified  Party to give  notice  as  provided  herein  shall not
     relieve the Indemnifying Party of its obligations under this Section 1.7.

                  (D)  Contribution.  If  recovery  is not  available  under the
foregoing  indemnification  provisions of this section for any reason other than
as  specified  therein,  the parties  entitled to  indemnification  by the terms
thereof shall be entitled to contribution  for liabilities and expenses,  except
to the extent that  contribution  is not permitted  under the Securities Act. In
determining  the amount of  contribution  to which the  respective  parties  are
entitled, there shall be considered the relative benefits received by each party
from the  offering of the  securities  (taking  into  account the portion of the
proceeds of the offering realized by each), the parties' relative  knowledge and
access to information  concerning the matter with respect to which the claim was
asserted, the party who supplied or failed to supply the information as to which
the claim is asserted,  the  opportunity to correct and prevent any statement or
omission,  and  any  other  equivalent  considerations   appropriate  under  the
circumstances.

         Section 1.8  Information  by Holder.  The Holder  shall  furnish to the
Company such information  regarding the Holder and the distribution  proposed by
the  Holder,  as the  Company may request in writing and as shall be required in
connection with any  registration,  qualification  or compliance  referred to in
this Agreement.

<PAGE>
         Section 1.9 No Transfer of Registration  Rights. The right to cause the
Company to register  Registrable  Securities pursuant to this Section may not be
assigned by Holder without the express written consent of the Company, which may
be withheld by the Company at its reasonable discretion.

         Section 1.10  Termination  of  Registration  Rights.  The  registration
rights  granted  pursuant to this Section 1 shall  terminate with respect to any
particular  Registrable  Securities  upon the  earlier  to occur of: (i) two (2)
years  from  the  date of  this  Agreement;  or (ii)  the  date  on  which  such
Registrable  Securities  are eligible for resale  pursuant to the  provisions of
Rule 144(k) of the Commission

         Section  1.11  Lockup.  In the event the Company  files a  registration
statement  with the  Commission  in  connection  with a public  offering  of the
Company's  securities,  Holder  agrees,  if so  requested  by the Company or the
underwriter  of such  offering,  that Holder  will not  effect,  or permit to be
effected on Holder's  behalf,  any public sale or  distribution of any shares of
capital  stock of the Company  (except as part of such  registration  and public
offering,  if so permitted) during the 30-day period beginning on the first date
of the effectiveness of such registration.

2.       MISCELLANEOUS.

         Section  2.1  Survival  of  Covenants;   Successors  and  Assigns.  All
covenants,  agreements,  representations  and warranties  made by the parties in
this Agreement  shall survive the closing of the  transactions  contemplated  by
this Agreement. All such covenants,  agreements,  representations and warranties
will inure to the  benefit of, and be binding  upon,  any  successors,  assigns,
heirs, transferees, executors, and administrators of the parties hereto.

         Section 2.2 Assignability of Rights.  The Company may not assign any of
its rights or  delegate  any of its  duties  under this  Agreement  without  the
written consent of Holder.

         Section 2.3  Communications  and Notices.  Except as otherwise provided
for in this  Agreement,  all  communications  and notices  provided  for in this
Agreement  shall be in writing and will be given by  telegram,  facsimile  (with
delivery  confirmed by the party giving notice),  express courier holding itself
out as able to make delivery  within one business day of receipt,  hand delivery
receipted by the addressee,  or by mail  (postage-paid,  certified mail,  return
receipt requested) to such address and for such attention, as any party may from
time to time  designate  by notice in writing to the Company or to the Holder as
the case may be. Notice will be effective  one business day after  delivery to a
telegraph  company or express courier,  three business days after deposit in the
U.S.   Mail  as  provided   above,   or  upon  receipt  if   hand-delivered   or
facsimile-delivered, as the case may be.

         Section 2.4 Law Governing. This Agreement shall be governed by the Laws

they will execute any further  instruments  and perform any acts that may become
necessary to carry out this Agreement.

         Section  2.6  Severability.  If  any  term,  provision,   covenant,  or
condition of this Agreement,  or its application to any person or  circumstance,
shall be held by a court of competent jurisdiction to be invalid, unenforceable,
or void, the remainder of this Agreement and such term, provision,  covenant, or
condition  as applied to other  persons or  circumstances  shall  remain in full
force and effect.

         Section 2.7       Entire Agreement; Amendments.

                  (A) This  Agreement  and the other  documents  and  agreements
delivered   pursuant  hereto  constitute  the  full  and  entire  agreement  and
understanding among the parties with regard to the subjects hereof and thereof.

                  (B) This  Agreement  may not be amended  orally.  Amendment to
this Agreement,  or of any supplement,  and of the rights and obligations of the
Company  and of the  Holder,  may be made  only by the  Company  and  Holder  in
writing.

         Section 2.8 Delays,  Omissions,  and  Waivers.  No delay or omission to
exercise  any  right,  power or  remedy  (with  the  exception  of a delay by an
Indemnified  Party in providing  notice to the  Indemnifying  Party  pursuant to
Section  1.7(C)  hereof)  accruing to the Company or Holder,  upon any breach or
default of any party  hereto under this  Agreement,  will impair any such right,
power or remedy of the Company or Holder nor will it be construed to be a waiver
of any such breach or default, or an acquiescence  therein, nor will any similar
breach or default be deemed a waiver of any other breach or default  theretofore
or thereafter occurring;  nor will any waiver of any single breach or default be
deemed a waiver  of any  other  breach  or  default  theretofore  or  thereafter
occurring.  Any waiver,  permit, consent or approval of any kind or character on
the part of the  Company  or  Holder  of any  provision  or  conditions  of this
Agreement,  must  be in  writing  and  will  be  effective  only  to the  extent
specifically set forth in such writing. No waiver by the Holder of any provision
of this Agreement will be effective without a written consent signed by Holder.

         Section 2.9 Authorization.  Each of the undersigned  representatives of
the parties  warrants and represents  that he is duly authorized to execute this
Agreement  on behalf of the  respective  party for which he signs,  and that the
organization  on whose  behalf he signs is  currently  in good  standing  in the
jurisdiction where organized.

               (c) By reason of Investor's  business and  financial  experience,
          Investor  has the  capacity  to  evaluate  the merits and risks of the
          prospective investment in the Debentures.

               (d) Investor has been  informed that all  documents,  records and
          books  pertaining to the Company and this investment were at all times
          available to Investor. Investor has utilized such access to Investor's
          satisfaction  for the purpose of obtaining  information  regarding the
          investment.  All  documents,  records  and  books  pertaining  to this
          investment  requested by Investor have been made available to Investor
          and the persons  Investor has retained to advise Investor with respect
          to this investment.  Investor and such persons have been supplied with
          such  additional  information  concerning this investment as they have
          requested.

               (e)  To  the  extent  Investor  deemed  necessary,  Investor  has
          consulted  with  Investor's  attorney  and/or  Investor's   accountant
          regarding  all aspects of the proposed  investment,  including the tax
          aspects  thereof,  and if requested by Investor,  said attorney and/or
          accountant  have  reviewed and analyzed the  Memorandum  on Investor's
          behalf.

               (f)  Investor  has adequate  means of  providing  for  Investor's
          current needs and possible financial  contingencies,  and has no need,
          and  anticipates  no  need in the  foreseeable  future,  to  sell  the
          Debentures.  Investor  is able  to bear  the  economic  risks  of this
          investment and,  consequently,  without limiting the generality of the
          foregoing,  is able to hold the Debentures for an indefinite period of
          time and has a  sufficient  net worth to  sustain a loss of the entire
          investment in the Company in the event such loss should occur.

               (g) Investor is the sole party in interest as to Debentures being
          acquired  by  the  Investor  and  is  acquiring  the   Debentures  for
          Investor's own account, for investment only and not with a view toward
          the resale or distribution thereof.

               (h)  Investor  understands  that the  Debentures,  the  shares of
          Series A Preferred Stock into which the Debentures are convertible and
          the shares of Common  Stock  issuable as  interest on the  Debentures,
          dividends on the Preferred Stock and into which the Debentures  and/or
          the shares of Series A Preferred Stock are  convertible  (collectively
          the  Debentures,  Series A  Preferred  Stock and the Common  Stock are
          referred  to  as  the  "Securities")  are  not  registered  under  the
          Securities  Act of 1933 (the "1933 Act") and may not be resold  unless
          registered under the 1933 Act or

         an exemption from such registration is available.  Investor agrees that
         Investor will not attempt to dispose of Investor's Securities except in
         compliance with the Act. The  certificates  representing the Securities
         shall bear appropriate  legends describing the restricted  character of
         the Securities.

               (i) Investor has not  distributed  the Memorandum to anyone other
          than Investor's advisors, accountant and/or attorney, and no one other
          than Investor's advisors, accountant and/or attorney and Investor have
          used the Memorandum.

               (j) Investor has the authority to purchase the  Debentures and to
          execute any other instruments or documents  required to be executed in
          connection with a purchase of Debentures.

               (k) Except as Investor  has  specifically  advised the Company in
          writing,  a copy of  which  has  been  attached  to this  Subscription

     meet any bona fide offer  which the  Company  has for such  financing.  The
     Investor  shall  have two  business  days from the date  notice of any such

     Company shall be free to accept and complete such financing, provided it is
     on terms no less  favorable  to the third  party than those  offered to the
     Investor.  In the  event  there is a  material  change in the terms of such
     financing  which  results in terms  more  favorable  to the third  party as
     compared to those  offered to the  Investor,  or if the  Company  fails not
     complete the financing on terms no less favorable to third party than those
     offered to the Investor,  within sixty (60) days of the date it became able
     to do so free of the rights  granted to the  Investor  hereunder,  then the
     Company shall again offer such  financing to the Investor,  and a new right

     with the laws of the State of Colorado, excluding, however, so much of said
     law as relates to conflict of laws and/or choice of law.

     regarding the purchase of the Debentures.  The provisions of this Agreement
     may not be modified or waived except in writing.

         2.2.      Exercise Procedure.

          (a). This Warrant shall be deemed to have been  exercised at such time
     as the Company  has  received  all of the  following  items (the  "Exercise
     Date"):

               i. A completed Exercise Agreement,  as described below,  executed
          by  the  Person   exercising  all  or  part  of  the  purchase  rights
          represented by this Warrant (the "Purchaser");

               ii.  This  Warrant  (subject  to delivery by the Company of a new
          Warrant  with  respect to any  unexercised  portion,  as  provided  in
          Paragraph (b) of Subsection 2.2);

               iii.  If  this  Warrant  is not  registered  in the  name  of the
          Purchaser, an Assignment or Assignments  substantially in the form set
          forth as Exhibit II hereto,  evidencing the assignment of this Warrant
          to the Purchaser; and

               iiii.  If  the  Purchaser  has  elected  not to  make a  Cashless
          Exercise  as  provided  in  Paragraph  (b) of this  Subsection  2.2, a
          certified  or bank  check  or other  certified  funds  payable  to the
          Company  in an  amount  equal to the  product  of the  Exercise  Price
          multiplied by the number of Stock being purchased upon such exercise.

          (b)  Certificates  for Stock  purchased  upon exercise of this Warrant
     shall be delivered by the Company to the Purchaser within five (5) business
     days after the Exercise Date. However, if the Purchaser has elected to make
     a  "Cashless  Exercise"  as herein  described,  the Company  shall  deliver
     certificates for the number of shares that results from  subtracting,  from
     the total number of Stock otherwise  deliverable upon exercise,  the number
     of Stock whose value,  calculated  using the Market Price,  is equal to the
     value of the payment  otherwise  required for exercise by Paragraph (a)(iv)
     of this  Subsection  2.2.  Unless  this  Warrant  has expired or all of the
     purchase rights represented hereby have been exercised,  the Company shall,
     in  addition  to  certificates  for Stock,  prepare  upon  exercise of this
     Warrant, a new Warrant representing the rights formerly represented by this
     Warrant that have not expired or been exercised.  The Company shall, within
     five (5) business days after the Exercise Date, deliver such new Warrant to
     the Persons designated for delivery in the Exercise Agreement.

          (c) Except as otherwise  required by Paragraph (b) of this  Subsection
     2.2, the Stock  issuable  upon the exercise of this Warrant shall be deemed
     to  have  been  issued  to the  Purchaser  on the  Exercise  Date,  and the
     Purchaser shall be deemed for all purposes to have become the record holder
     of such Stock on the Exercise Date.

          (d) The  issuance  of  certificates  for Stock upon  exercise  of this
     Warrant  shall be made  without  charge  to the  Registered  Holder  or the
     Purchaser for any issuance tax

                                       -4-
<PAGE>
     in respect  thereof or any other cost incurred by the Company in connection
     with such exercise and the related issuance of Stock.

          (e) The  Company  shall not close its books for the  transfer  of this
     Warrant  or of any Stock in any  manner  that  interferes  with the  timely
     exercise of this Warrant. The Company shall from time to time take all such
     action as may be  necessary  to assure  that the par value per share of the
     unissued  Stock is at all times  equal to or less than the  Exercise  Price
     then in effect.

        2.3. Exercise  Agreement.  The Exercise Agreement shall be substantially
in the form set forth as  Exhibit I  hereto,  except  that if Stock is not to be
issued  in the name of the  Registered  Holder  of this  Warrant,  the  Exercise
Agreement  shall  also  state  the name of the  Persons  to whom  Stock is to be
issued,  and if the number of Stock purchased does not include all of such Stock
purchasable  hereunder,  it shall also state the name of the Persons to whom new
Warrants  for  the  unexercised  portion  of  the  rights  hereunder  are  to be
delivered.  Any  transfer  of Stock to a person  other  than a prior  Registered
Holder shall occur only in compliance  with the  provisions  regarding  transfer
contained in Section 12 of this Warrant.

        2.4.  Fractional  Portions of Stock.  If a  fractional  portion of Stock
would be issuable upon exercise of the rights  represented by this Warrant,  the
Company shall,  within three (3) business days after the Exercise Date,  deliver
to the Purchaser a check payable to the  Purchaser,  in lieu of such  fractional
portion  of Stock,  in an amount  equal to the Market  Price of such  fractional
portion of Stock as of the close of business on the Exercise Date.


                                   SECTION 3.
                                 EXERCISE PRICE

         3.1.      General.

          (a) The  initial  Exercise  Price of this  Warrant is set forth on the
     front  page of this  Warrant.  In order to prevent  dilution  of the rights
     granted  under  this  Warrant,  the  Exercise  Price  shall be  subject  to
     adjustment from time to time pursuant to this Section 3.

          (b) If and whenever the Company issues or sells, or in accordance with
     Subsection  3.3 is deemed to have issued or sold,  any shares of its Common
     Stock for a  consideration  per share less than the Market  Price in effect
     immediately prior to the time of such issuance or sale (except as otherwise
     provided by Subsection  3.2), then  immediately  upon each such issuance or
     sale,  the  Exercise  Price  shall  be  reduced  to a price  determined  by
     multiplying the Exercise Price in effect  immediately prior to the issuance
     or sale by a fraction,  the  numerator of which shall be the sum of (i) the
     number of shares of Common Stock actually outstanding prior to the issuance
     or sale,  and (ii) the number of shares of Common  Stock  that the  minimum
     aggregate  amount  receivable  by the Company upon such issuance or sale on
     that occasion would purchase at the initial Exercise Price, and the

                                       -5-

<PAGE>
     denominator of which shall be the number of shares of Common Stock actually
     outstanding  and Common  Stock  Deemed  Outstanding  under  Subsection  3.3
     immediately after such issuance or sale.

        3.2. No  Adjustments  in Certain  Cases.  No  adjustment to the Exercise
Price under  Paragraph (b) of Subsection 3.1 or under  Subsection 3.3, or to the
number of shares issuable upon exercise of this Warrant under Section 4 shall be
made:

          (a) for the existence of, and any exercise, conversion or issuance of,
     any Common Stock or other  security of the Company  under (a) the Warrants;
     (b) any option,  warrant,  or other right to purchase  Common Stock that is
     outstanding  on the  Agreement  Date,  (c)  any  option  issued  under  the
     Company's  1992 Stock Option Plan, as in effect on the Agreement  Date, (d)
     the Debentures  (including the issuance of preferred  stock upon conversion
     of the Debentures  and the issuance of Common Stock as interest,  dividends
     or upon conversion of the Debentures and/or such preferred stock); or

          (b) upon the issuance of Common Stock upon  exercise or  conversion of
     any option,  warrant or other  right or  Convertible  Securities  for which
     adjustments  have  previously  been  made  upon  issuance  of such  option,
     warrant, right or Convertible Securities.

        3.3.  Effect on  Exercise  Price of  Certain  Events.  For  purposes  of
determining  the  adjusted  Exercise  Price  under  Subsection  3.1  above,  the
following provisions shall be applicable:

          (a)  Issuance  of Rights  and  Options.  If the  Company in any manner
     grants any rights or options to subscribe  for or to purchase  Common Stock
     or any  stock or other  securities  convertible  into or  exchangeable  for
     Common Stock (such rights or options being herein called "Options" and such
     convertible  or  exchangeable  stock  or  securities  being  herein  called
     "Convertible Securities") and the price per share for which Common Stock is
     issuable  upon the exercise of such Options or upon  conversion or exchange
     of such  Convertible  Securities  is less than the  Market  Price in effect
     immediately  prior to the time of the  granting of such  Options,  then the
     total maximum  number of shares of Common Stock  issuable upon the exercise
     of such Options or upon  conversion or exchange of the total maximum amount
     of such  Convertible  Securities  shall be deemed to be outstanding  and to
     have been  issued and sold by the  Company  for such  price per share.  For
     purposes of this paragraph,  the "price per share for which Common Stock is
     issuable  upon  exercise of such Options or upon  conversion or exchange of
     such Convertible  Securities" shall be determined by dividing (i) the total
     amount,  if any,  received by the Company as consideration for the granting
     of  such  Options  plus  the  minimum   aggregate   amount  of   additional
     consideration  payable to the Company  upon  exercise  of all such  Options
     plus, in the case of Options that relate to the Convertible Securities, the
     minimum  aggregate amount of additional  consideration,  if any, payable to
     the Company upon the conversion or exchange of such Convertible Securities,
     by (ii) the total maximum number of shares of Common Stock

                                       -6-
<PAGE>
     issuable  upon the  exercise  of such  Options and upon the  conversion  or
     exchange of all Convertible  Securities  issuable upon the exercise of such
     Options.

          (b) Issuance of Convertible  Securities.  If the Company in any manner
     issues or sells  any  Convertible  Securities,  and the price per share for
     which  Common  Stock  is  issuable  upon  conversion  or  exchange  or such
     Convertible  Securities is less than the Market Price in effect immediately
     prior to the time of such  issuance  or sale,  then the  maximum  number of
     shares of Common Stock  issuable  upon  conversion  or exchange of all such
     Convertible  Securities  shall be deemed to be outstanding and to have been
     issued and sold by the  Company for such price per share.  For  purposes of
     this  paragraph,  the "price per share for which  Common  Stock is issuable
     upon such  conversion or exchange"  shall be determined by dividing (i) the
     total amount received by the Company as  consideration  for the issuance or
     sale of such Convertible  Securities,  plus the minimum aggregate amount of
     additional  consideration,   if  any,  payable  to  the  Company  upon  the
     conversion or exchange thereof,  by (ii) the total maximum number of shares
     of Common  Stock  issuable  upon the  conversion  or  exchange  of all such
     Convertible Securities.

          (c) Change in Option Price and  Conversion  Rate.  If any change shall
     occur in the price per share provided for in any of the options,  rights or
     warrants  referred to in Paragraph  (a) of this  Subsection  3.3, or in the
     price  per  share  at  which  the  Convertible  Securities  referred  to in
     Paragraph (b) of this Subsection 3.3 are convertible or exchangeable,  such
     options,  rights or warrants or conversion or exchange rights,  as the case
     may be, shall be deemed to have expired or terminated on the date when such
     price change became  effective in respect of shares not theretofore  issued
     pursuant to the exercise or conversion or exchange thereof, and the Company
     shall be  deemed to have  issued  upon  such  date new  options,  rights or
     warrants  or  Convertible  Securities  at the new price in  respect  of the
     number of shares  issuable  upon the  exercise of such  options,  rights or
     warrants or the conversion or exchange of such Convertible Securities.

          (d)  Calculation  of  Consideration  Received.  If any  Common  Stock,
     Options,  or  Convertible  Securities  are issued or sold or deemed to have
     been issued or sold or consideration that includes  unrestricted cash, then
     the amount of cash consideration  actually received by the Company shall be
     deemed  to be the full  monetary  value of the  unrestricted  cash  portion
     thereof. If any Common Stock, Options or Convertible  Securities are issued
     or sold or deemed to have been issued or sold for a  consideration  part or
     all of  which is other  than  unrestricted  cash,  then the  amount  of the
     consideration other than unrestricted cash received by the Company shall be
     deemed to be the Fair Value of such consideration.

          (e)  Integrated  Transactions.  If any Option is issued in  connection
     with the  issuance or sale of other  securities  of the  Company,  together
     compromising one integrated  transaction in which no specific consideration
     is  allocated  to such Option by the parties  thereto,  the Option shall be
     deemed to have been issued without consideration.


                                       -7-
<PAGE>
          (f)  Treasury  Shares.  The  number of shares of Common  Stock  Deemed
     Outstanding  at any given time shall not include shares owned or held by or
     for the account of the Company,  and the disposition of any shares so owned
     or held shall be considered an issuance or sale of Common Stock.

          (g) Readjustment Upon Expiration of Options or Convertible Securities.
     Upon the expiration of any of the options,  warrants or rights  referred to
     in Paragraph  (a) of this  Subsection  3.3, or the  Convertible  Securities
     referred to in  Paragraph  (b) of this  Subsection  3.3,  if such  options,
     warrants,  rights or Convertible  Securities shall not have been exercised,
     converted  or  exchanged,  as the case may be, the Exercise  Price,  to the
     extent that Warrants have not been exercised,  shall, upon such expiration,
     be  readjusted  and  shall  thereafter  be set (A) if any of such  options,
     warrants or rights have been exercised or such Convertible  Securities have
     been  converted or  exchanged,  as the case may be, at a level at which the
     Exercise  Price would have been if originally  adjusted on the basis of (i)
     the fact that the only shares of Common  Stock so issued were the shares of
     Common  Stock,  if any,  actually  issued or sold upon the exercise of such
     options,  warrants  or  rights  or  the  conversion  or  exchange  of  such
     Convertible  Securities and (ii) such shares of Common Stock,  if any, were
     issued or sold for the  consideration  actually received by the Company for
     the  issuance,  sale or grant  of all such  options,  warrants,  rights  or
     Convertible  Securities,  whether or not exercised,  plus the consideration
     actually received by the Company upon the exercise,  conversion or exchange
     of such options, warrants, rights or Convertible Securities, or (B) if none
     of such options, warrants or rights have been exercised or such Convertible
     Securities have been converted or exchanged, as the case may be, at a level
     at which the Exercise Price would have been if such original adjustment had
     not been required;  provided, however, that no such readjustment shall have
     the effect of increasing the Exercise Price in effect  immediately prior to
     such readjustment by a proportion  greater than the aggregate  proportional
     adjustment  originally made upon the issue,  sale or grant of such options,
     warrants, rights, or Convertible Securities.

        3.4. Subdivision and Combination of Common Stock;  Stock  Dividends.  If
the  Company  shall at any time  after the date  hereof  (a) issue any shares of
Common Stock or Convertible  Securities,  or any rights to purchase Common Stock
or Convertible  Securities as a dividend upon Common Stock, (b) issue any shares
of  Common  Stock in  subdivision  of  outstanding  shares  of  Common  Stock by
reclassification, stock split or otherwise, or (c) combine outstanding shares of
Common Stock by  reclassification,  reverse stock split or  otherwise,  then the
Exercise  Price  that  would  apply if  purchase  rights  hereunder  were  being
exercised  immediately  prior to such action by the Company shall be adjusted by
multiplying  it by a  fraction,  the  numerator  of which shall be the number of
shares of Common Stock Deemed  Outstanding  immediately  prior to such dividend,
subdivision or combination  and the  denominator of which shall be the number of
shares of Common  Stock  Deemed  Outstanding  immediately  after such  dividend,
subdivision or combination.

    3.5. Certain  Dividends  and  Distributions.  If the Company shall declare a
dividend or  distribution  upon the Common Stock payable  otherwise  than out of
earnings or

                                       -8-
<PAGE>
earned  surplus  and  otherwise  than in Common  Stock,  Options or  Convertible
Securities,  the Exercise Price shall be reduced by an amount equal, in the case
of a dividend or  distribution  in cash, to the amount thereof payable per share
of the Common Stock or, in the case of any other  dividend or  distribution,  to
the Fair Value of such dividend or distribution  per share of Common Stock.  For
purposes of the foregoing,  a dividend or distribution  other than in cash shall
be considered  payable out of earnings or earned surplus only to the extent that
such earnings or earned surplus are charged an amount equal to the Fair Value of
such dividend or distribution.  Such reductions shall take effect as of the date
on which a record is taken for the purpose of such divided or distribution,  or,
if a record is not taken,  the date as of which the  holders of Common  Stock of
record  entitled to such  dividend or  distribution  are to be  determined.  The
adjustment  called  for by this  Subsection  3.5 shall  not  apply to  dividends
payable on the preferred stock issuable upon conversion of the Debentures.

        3.6. Manner of Calculating Adjustments;  No De Minimis Adjustments.  The
calculation  of each  adjustment of the Exercise Price shall be made accurate to
the nearest ten-  thousandth.  No adjustment of the Exercise Price shall be made
if the amount of such adjustment  would be less than one cent per share. In such
case any adjustment that otherwise would be required to be made shall be carried
forward  and  shall be made at the time and  together  with the next  subsequent
adjustment that, together with any adjustment or adjustments so carried forward,
shall amount to not less than one cent per share.


                                   SECTION 4.
              ADJUSTMENT OF NUMBER OF STOCK ISSUABLE UPON EXERCISE

         Upon each reduction of the Exercise Price pursuant to Section 3 hereof,
the  Registered  Holder  shall  thereafter  (until  another such  reduction)  be
entitled  to  purchase,  at the  Exercise  Price in effect on the date  purchase
rights under this Warrant are exercised,  the number of Stock, calculated to the
nearest whole number of Stock, determined by (a) multiplying the number of Stock
purchasable  hereunder  immediately prior to the reduction of the Exercise Price
by the Exercise Price in effect  immediately  prior to such  reduction,  and (b)
dividing the product so obtained by the Exercise  Price in effect on the date of
such exercise.


                                   SECTION 5.
                   EFFECT OF REORGANIZATION, RECLASSIFICATION,
                CONSOLIDATION, MERGER, SALE OR OTHER DISPOSITION

         If at any time while this  Warrant is  outstanding  there  shall be any
reorganization  or  reclassification  of the capital stock of the Company (other
than a subdivision  or  combination  of shares  provided for in  Subsection  3.4
hereof),  any  consideration  or merger of the Company with another  corporation
(other  than a  consolidation  or merger in which the  Company is the  surviving
entity and which does not result in any change in the Common

                                       -9-
<PAGE>
Stock),  or any sale or other disposition by the Company of all or substantially
all of its assets to any other  corporation,  then the  Registered  Holder shall
thereafter  upon  exercise of this  Warrant be entitled to receive the Stock and
other  securities and property of the Company,  or of the successor  corporation
resulting from  consolidation or merger, as the case may be, to which Purchasers
of Stock would have been entitled upon such  reorganization,  reclas- sification
of capital  stock,  consolidation,  merger,  sale or other  disposition  if this
Warrant  has  been   exercised   immediately   prior  to  such   reorganization,
reclassification,  consolidation, merger, sale or other disposition. In any such
case,  appropriate  adjustment  (as  determined  in good  faith by the  Board of
Directors of the Company) shall be made in the application of the provisions set
forth in this Warrant with respect to the rights and interests thereafter of the
Registered Holder to the end that the provisions set forth in this Warrant shall
thereafter be applicable, as near as reasonably may be, in relation to any Stock
or other securities or property thereafter  deliverable upon the exercise hereof
as if this Warrant had been exercised  immediately prior to such reorganization,
reclassification  of  capital  stock,  consolidation,   merger,  sale  or  other
disposition  and the  Registered  Holder hereof had carried out the terms of the
exchange as provided  for by such  reorganization,  reclassification  of capital
stock,  consolidation,  merger,  sale  or  other  disposition.  If in  any  such
reorganization,  reclassification of capital stock, consolidation,  merger, sale
or other  disposition,  additional  shares  of Common  Stock  shall be issued in
exchange, conversion,  substitution or payment, in whole or in part, for or of a
security of the Company  other than Common Stock  deliverable  from  exercise of
this  Warrant,  any such  issue  shall be  treated  as an issue of Common  Stock
covered by the  provisions  of  Section 3, with the amount of the  consideration
received  upon  the  issue  thereof  being  determined  under  Paragraph  (e) of
Subsection   3.3.  The  Company  shall  not  effect  any  such   reorganization,
reclassification  of  capital  stock,  consolidation,   merger,  sale  or  other
disposition  unless,  upon or prior to the consummation  thereof,  the successor
corporation shall assume by written  instrument the obligation to deliver to the
Registered Holder such shares of stock or other securities,  cash or property as
such  Registered  Holder shall be entitled to purchase in  accordance  with this
Warrant's provisions.


                                   SECTION 6.
                              NOTICE OF ADJUSTMENT

         Immediately  upon any  adjustment  of the Exercise  Price,  the Company
shall  send  written  notice  thereof to all  Registered  Holders,  stating  the
adjusted  Exercise  Price and the number of Stock  purchasable  upon exercise of
this Warrant and setting  forth in reasonable  detail the method of  calculation
for such  adjustment.  When possible,  such notice shall be given in advance and
included as part of any notice required to be given pursuant to Section 7 below.

                                   SECTION 7.
                         PRIOR NOTICE OF CERTAIN EVENTS

         If at any time:

          (a) The  Company  shall pay any  dividend  payable  in stock  upon its
     Common Stock or make any  distribution  (other than cash  dividends) to the
     holders of its Common Stock of record;

          (b) The Company shall offer for  subscription  pro rata to the holders
     of its Common Stock of record any  additional  shares of stock of any class
     or any other rights;

          (c)  There  shall be any  reorganization  or  reclassification  of the
     capital stock of the Company,  any  consolidation  or merger of the Company
     with  another  corporation,  or a  sale  or  other  disposition  of  all or
     substantially all its assets;

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

          (e) The Company shall file any registration  statement pursuant to the
     Securities Act of 1933, as amended (the "Act"),

then, in each such case, the Company shall give prior written notice of the date
on which (i) the books of the Company shall close or a record shall be taken for
such stock  dividend,  distribution,  subscription  or other rights or (ii) such
reorganization,   reclassification,   consolidation,   merger,   sale  or  other
disposition,  dissolution,  liquidation,  winding up or filing of a registration
statement shall take place, as the case may be. A copy of each such notice shall
be sent  simultaneously  to each transfer  agent of the Company's  Common Stock.
Such notice  shall also specify the date as of which the holders of Common Stock
of  record  shall  participate  in said  dividend,  distribution,  subscription,
registration or other rights or shall be entitled to exchange their Common Stock
for  securities  or  other  property  deliverable  upon  such  reclassification,
consolidation,  merger,  sale or other  disposition,  dissolution,  liquidation,
winding  up or  filing,  as the case may be,  and in any  case  contemplated  by
Paragraph (d) of Subsection 3.3, shall include the Company's  calculation of the
Fair Value of the consideration  whose Fair Value requires  determination.  Such
written notice shall be given at least thirty (30) days prior to the record date
or the effective or filing date,  whichever is earlier, of the subject action or
other event.  The failure by the Company to give any such notice shall not serve
to invalidate any action otherwise validly taken by the Company.

                                   SECTION 8.
                           RESERVATION OF COMMON STOCK

         The Registered Holder understands that as of the Date of Issuance,  the
Company does not have an adequate  number of shares of  authorized  Common Stock
available  to satisfy the  outstanding  rights of all  securityholders  who hold
options,  warrants or other rights which are exercisable for or convertible into
shares of the Company's Common Stock. The Company has implemented  steps to hold
a meeting of shareholders to authorize an increase in authorized Common Stock to
no less than 40,000,000 shares (the "Capital Increase"). The Company agrees that
it shall use its best  efforts  to hold such  shareholder  meeting no later than
April 30, 1998.  Assuming adoption of the Capital Increase at such meeting,  the
Company shall at all times  thereafter  reserve and keep  available for issuance
upon the exercise of the  Warrants  such number of its  authorized  but unissued
shares of Common Stock as will be  sufficient  to permit the exercise in full of
all  outstanding  Warrants,  and upon such  issuance such shares of Common Stock
will be validly issued,  fully paid and nonassessable.  In the event the Company
does not hold a  meeting  of its  shareholders  by  April  30,  1998 at which it
presents  the  Capital  Increase,  or in the event the  Capital  Increase is not
approved by the Company's  shareholders at such meeting,  then at any time after
April 30, 1998, any registered Holder exercising  Warrants for which the Company
is  unable to issue  shares of Common  Stock  shall be  entitled  to have  their
Warrants  repurchased  by the  Company for a price equal to the number of shares
not issuable by the Company as a result of such deficiency  times the difference
between the Market Price on the Exercise Date and the Exercise Price.

                                   SECTION 9.
                       NO SHAREHOLDER RIGHTS OR OBLIGATION

         This  Warrant  shall not  entitle the  Registered  Holder to any voting
rights or other rights as a  shareholder  of the  Company.  No provision of this
Warrant,  in the  absence  of  affirmative  action by the  Registered  Holder to
purchase  Stock,  and no enumeration in this Warrant of the rights or privileges
of the Registered  Holder,  shall give rise to any obligation of such Registered
Holder for the payment of the  Exercise  Price of Stock  acquirable  by exercise
hereof (in absence of such actual exercise) or as a shareholder of the Company.

                                   SECTION 10.
                    EXCHANGEABLE FOR DIFFERENT DENOMINATIONS

         This  Warrant  is  exchangeable,  upon  the  surrender  hereof  by  the
Registered  Holder at the principal  office of the Company,  for new Warrants of
like tenor  representing in the aggregate the purchase rights hereunder,  as set
forth on the front page  hereof,  and each of such new Warrants  will  represent
such portion of such rights as is  designated  by the  Registered  Holder at the
time of such  surrender.  The date the Company  initially  issued this  Warrant,
which is set forth on the front page hereof,  shall be deemed to be the "Date of
Issuance" of this Warrant and any Warrant  exchanged or  substituted  therefore,
regardless of
                                      -12-
<PAGE>
the dates on which new  Warrants  representing  the  unexpired  and  unexercised
rights formerly represented by this Warrant are issued.


                                   SECTION 11.
                                 TRANSFERABILITY

         Subject only to the transfer conditions referred to in this Section 11,
this Warrant and all rights  hereunder  are  transferable,  in whole or in part,
without  restriction and without charge to the Registered Holder, upon surrender
of this Warrant with a properly executed  Assignment  (substantially in the form
of Exhibit II hereto) at the principal  office of the Company.  This Warrant and
the Stock issued upon exercise  hereof may not be offered,  sold or  transferred
except in compliance with the Act and any applicable  state securities laws, and
then only  against  receipt of an  agreement of the Person to whom such offer or
sale is made to comply with the  provisions  of this  Section 11 with respect to
any  resale or other  disposition  of such  securities;  provided,  that no such
agreement shall be required from any Person purchasing this Warrant or any Stock
pursuant to a  registration  statement  effective  under the Act. The Registered
Holder  agrees  that,  prior to the  disposition  of any Stock  purchased on the
exercise  hereof under  circumstances  that might require  registration  of such
Stock under the Act,  or any  similar  statute  then in effect,  the  Registered
Holder shall give written notice to the Company,  expressing its intention as to
such  disposition.  Within three (3) business days after  receiving such notice,
the Company shall present a copy thereof to its securities  counsel.  If, in the
opinion of such counsel,  which shall be rendered  within five (5) business days
after  receiving such notice,  or in the opinion of the Registered  Holder's own
counsel  (which  shall be in form and from such  counsel as shall be  reasonably
satisfactory  to  the  Company),  the  proposed  disposition  does  not  require
registration of such Stock under the Act, or any similar statute then in effect,
the  Company  shall,  within  two (2)  business  days of the  rendering  of such
opinion, notify the Registered Holder of such opinion,  whereupon the Registered
Holder shall be entitled to dispose of such Stock in  accordance  with the terms
of the notice  delivered  by the  Registered  Holder to the  Company.  The above
agreement by the  Registered  Holder shall not be deemed to limit or restrict in
any respect the exercise of rights set forth in Section 12 hereof.

                                   SECTION 12.
                               REGISTRATION RIGHTS

         12.1.    Demand Rights.

          (a) Right to Demand  Registration.  On one (1)  occasion,  at any time
     during the Exercise  Period,  the  Registered  Holders of Warrants or Stock
     whose holdings  thereof  comprise a majority of Stock  purchasable upon the
     exercise of outstanding  Warrants and of  outstanding  Stock not previously
     covered by a  registration  statement  as  contemplated  by this Section 12
     (collectively,  the "Warrant  Securities")  shall have the right to require
     the Company to prepare and file with the Commission,  within 60 days of the
     date of a written

                                      -13-
<PAGE>
demand,  a filing on a registration  form other than Form S-8 or Form S-3 (or an
equivalent short-form  registration  procedure that the Commission may hereafter
prescribe),  and to use its best  efforts to obtain  promptly  and  maintain the
effectiveness  thereof  for at  least  one  hundred  twenty  (120)  days and (b)
register  or  qualify  the  subject  Stock  for  sale in up to ten  (10)  states
identified by such  Registered  Holders.  On two (2) additional  occasions,  the
Registered  Holders of a majority of the Warrant Securities shall have the right
to require the Company to prepare and file with the  Commission,  within  thirty
(30) days of the date of a written demand, up to two (2) additional registration
statements under the Act (or, in lieu of either,  a post-effective  amendment or
amendments to a registration  statement,  if then  permitted  under the Act), on
Form S-8 or Form S-3 (or an equivalent  short-form  registration  procedure that
the Commission may hereafter prescribe), if such forms are available to register
the Stock at the time,  covering all or any portion of the Stock  underlying the
Warrants,  and to use its best  efforts  to obtain  promptly  and  maintain  the
effectiveness  thereof  for at  least  one  hundred  twenty  (120)  days and (b)
register  or  qualify  the  subject  Stock  for  sale in up to ten  (10)  states
identified  by such  Registered  Holders.  The Company  shall bear all  expenses
incurred  in the  preparation  and  filing  of  the  registration  statement  or
post-effective  amendment  (and  related  state  registrations,  to  the  extent
permitted by applicable law) and the furnishing a reasonable number of copies of
the  preliminary  and  final  prospectus  thereof  to such  Registered  Holders,
provided  that such  registration  can be done by  including  therein  financial
statements  that are prepared in the normal  course of the  Company's  reporting
obligations under the federal securities laws. The Registered Holders shall bear
all  expenses  incurred  in the  preparation  and  filing  of  the  registration
statement or post-effective  amendment (and related state registrations,  to the
extent  permitted  by  applicable  law)  including  the  costs of  furnishing  a
reasonable  number of copies of the preliminary and final prospectus  thereof to
such Registered Holders,  if, after notice is given to the Registered Holders to
the effect that the  Company  would be  required  to include  therein  financial
statements  that would be required to be prepared  otherwise  than in the normal
course of the Company's reporting obligations under the federal securities laws,
the Registered Holders continue in their demand for registration and the Company
is required to include in such registration  financial statements required to be
prepared  other  than  in  the  ordinary  course  of  the  Company's   reporting
requirements under federal securities laws.

          (b) Termination of Demand Rights.  The demand rights granted hereunder
     shall  terminate  at such  time  as all of the  Stock  may be sold  without
     restriction  under  the  Act  and  applicable  state  securities  laws  and
     regulations,  and the  Registered  Holders  have  received an opinion  from
     counsel  for  the  Company  (in  such  form  and  from  counsel  reasonably
     satisfactory  to the  Registered  Holders)  that  all of  the  Stock  is so
     saleable under SEC Rule 144 or otherwise within the immediate 90-day period
     commencing on the date a sale is requested.

       12.2. "Piggyback" Rights. In addition, if at any time during the Exercise
Period, the Company shall prepare and file one or more post-effective amendments
to a registration  statement or a new registration statement under the Act, with
respect  to a public  offering  of equity  or debt  securities  of the  Company,
whether by the company or by other Persons, then

                                      -14-
<PAGE>
the Company shall include in any such  post-effective  amendment or registration
statement  such  information  as may be required to permit a public  offering of
Stock  held by any  Registered  Holders  requesting  inclusion  of their  Stock;
provided that where such offering is to be an underwritten  offering, and in the
opinion  of the  Company's  managing  underwriter  the  inclusion  of the  Stock
requested to be registered, when added to the other securities being registered,
would exceed the maximum amount of the company's securities that can be marketed
without otherwise  materially and adversely affecting the entire offering,  then
the Company may exclude from such  offering a portion of the Stock  requested to
be so  registered,  so that the total number of  securities  to be registered is
within  the  maximum  number of shares  that,  in the  opinion  of the  managing
underwriter,   may  be  marketed  without  otherwise  materially  and  adversely
affecting  the  entire  offering.  In the  event  there  are  previously  issued
securities  other  than the Stock  that are  proposed  to be  registered  in the
registration  pursuant to  registration  rights that were  granted  prior to the
rights granted  hereunder (the "Prior  Rights"),  then, the rights granted under
this  Subsection  12.2 shall be subject to all such Prior Rights,  and the Stock
may be  excluded  from such  registration  to the extent  that the Prior  Rights
require;  provided,  however,  that the  entire  amount of any other  securities
without  Prior  Rights  shall be  excluded  from such  registration  before  the
exclusion of any portion of the Stock for which  registration was requested by a
Registered  Holder.  Each  Registered  Holder of  Warrant  Securities  for whose
account any Stock may be included in a post-effective  amendment or registration
statement shall have the unrestricted  right to withhold Stock from inclusion in
the underwritten offering, without regard to whether registration was requested.
The Company shall bear all fees and expenses  incurred by it in connection  with
the preparation and filing of such post-effective  amendment or new registration
statement.  In the event of such a  proposed  registration,  the  Company  shall
furnish the then  Registered  Holders of Warrant  Securities  with not less than
thirty (30) days'  written  notice prior to the proposed  date of filing of such
post-effective  amendment  or new  registration  statement.  Such  notice  shall
continue to be given by the Company to Registered Holders of Warrant Securities,
with respect to subsequent registration statements or post-effective  amendments
filed by the  Company,  until such time as all of the Stock may be sold  without
restriction  under the Act and applicable state securities laws and regulations,
and the Registered Holders have received an opinion from counsel for the Company
(in  such  form and  from  counsel  reasonably  satisfactory  to the  Registered
Holders)  that all of the Stock is so saleable  under SEC Rule 144 or  otherwise
within the immediate  90-day period  commencing on the date a sale is requested.
The Registered  Holders of Warrant Securities shall exercise the rights provided
for in this  Subsection  12.2 by giving  written  notice to the Company,  within
twenty (20) days of receipt of the  Company's  notice of its intention to file a
post-effective amendment or new registration statement.

       12.3. Use of Prospectus.  The Registered  Holder,  upon receipt of notice
from the Company of the occurrence of an event which  requires a  post-effective
amendment to a  registration  statement  or an amendment or a supplement  to the
prospectus  included therein,  shall promptly  discontinue the sale of his Stock
until it has received  copies of a supplemented  or amended  prospectus from the
Company,  and  until  such  receipt,  the  running  of  any  minimum  period  of
effectiveness required by Subsection 12.1 shall be tolled.

                                      -15-
<PAGE>
        12.4. Failure  to  Supply  Information.  Registered  Holders  requesting
inclusion of Stock in any registration  statement filed by the Company shall, at
such  Holder's cost and expense,  cooperate  fully and promptly with the Company
and its counsel in supplying such information  concerning the Registered  Holder
and such Holder's plan of  distribution  as may reasonably be required to effect
such registration. Any Registered Holder who fails to so cooperate and to supply
information  to the  Company  that is  required  to  obtain  effectiveness  of a
registration  statement shall have such Registered  Holder's Stock excluded from
the registration  statement,  and such  registration  shall count as a completed
registration with respect to such Registered Holder.

       12.5. Withdrawal of Stock from  Registration.  Any Registered  Holder who
withdraws such Holder's Stock from any registration statement commenced pursuant
to Subsection  12.1 hereof,  at such Holder's  request,  shall be deemed to have
received full benefit of a completed registration under Subsection 12.1 hereof.

                                   SECTION 13.
                                 INDEMNIFICATION

          (a) By the Company.  The Company shall  indemnify,  to the full extent
     permitted by law, the  Registered  Holder,  its  directors and officers (if
     applicable)  and each person,  if any, who controls the  Registered  Holder
     within the meaning of Section 15 of the Act,  against  any losses,  claims,
     damages,  liabilities  and  expenses  resulting  from any untrue or alleged
     untrue   statement  of  a  material  fact  contained  in  any  registration
     statement,  prospectus or preliminary prospectus or any omission or alleged
     omission to state therein a material fact  necessary to make the statements
     therein (in the case of the prospectus or any  preliminary  prospectus,  in
     light of the  circumstances  under  which they were  made) not  misleading,
     except  insofar as the same are caused by or contained  in any  information
     with respect to the Registered  Holder  furnished in writing to the Company
     by the Registered Holder expressly for use therein.

          (b) By the  Registered  Holder.  In connection  with any  registration
     statement in which the Registered Holder is  participating,  the Registered
     Holder shall  indemnify,  to the full extent permitted by law, the Company,
     its directors and officers and each person who controls the Company (within
     the meaning of Section 15 of the Act) against any losses, claims,  damages,
     liabilities  and  expenses  resulting  from any  untrue or  alleged  untrue
     statement  of a material  fact  contained  in any  registration  statement,
     prospectus or preliminary prospectus or any omission or alleged omission to
     state therein a material fact necessary to make the statements  therein (in
     the case of the prospectus or any preliminary  prospectus,  in light of the
     circumstances under which they were made) not misleading,  but only insofar
     as the same are caused by or contained in any  information  with respect to
     the Registered Holder furnished in writing to the Company by the Registered
     Holder expressly for use therein.


                                      -16-
<PAGE>
          (c)Indemnification   Procedures.   Any  person  who  is   entitled  to
     indemnification  under this Section 13 shall (i) give prompt written notice
     to the  indemnifying  party of any  claim  with  respect  to which it seeks
     indemnification  and (ii)  permit  such  indemnifying  party to assume  the
     defense  of  such  claim  with  counsel  reasonably   satisfactory  to  the
     indemnified  party.   Whether  or  not  such  defense  is  assumed  by  the
     indemnifying  party,  the  indemnifying  party  shall not be subject to any
     liability  for any  settlement  made without its consent.  No  indemnifying
     party shall  consent to entry of any judgment or enter into any  settlement
     which does not include as an  unconditional  term thereof the giving by the
     claimant  or  plaintiff  to such  indemnified  party of a release  from all
     liability in respect of such claim or litigation. An indemnifying party who
     is not entitled  to, or elects not to,  assume the defense of a claim shall
     not be  obligated to pay the fees and expenses of more than one counsel for
     all parties  indemnified  by such  indemnifying  party with respect to such
     claim,  unless  in the  reasonable  judgment  of any  indemnified  party  a
     conflict of interest  may exist  between such  indemnified  party and other
     indemnified  parties  with  respect  to such  claim,  in  which  event  the
     indemnifying  party shall be obligated to pay the fees and expenses of such
     additional counsel or counsels.

          (d) Contribution.  If for any reason an  indemnification  provision of
     this  Section  13 is  held  by a  court  of  competent  jurisdiction  to be
     unavailable  to an  indemnified  party  with  respect  to any loss,  claim,
     damage,  liability or expense  referred to therein,  then the  indemnifying
     party, in lieu of indemnifying  each indemnified  party  thereunder,  shall
     contribute  to the amount  paid or payable  by the  indemnified  party as a
     result of any such  loss,  claim,  damage,  liability  or  expense  in such
     proportion  as is  applicable  to reflect  not only the  relative  benefits
     received by the indemnified party and the indemnifying  party, but also the
     relative fault of the indemnified party and indemnifying  party, as well as
     any other  relevant  equitable  considerations.  The relative  fault of the
     indemnifying  party and of the  indemnified  party shall be  determined  by
     reference  to,  among other  things,  whether any untrue or alleged  untrue
     statement of a material fact or omission to state  material fact relates to
     information  supplied by the indemnifying party or by the indemnified party
     and the parties'  relative  intent,  knowledge,  access to information  and
     opportunity to correct or prevent such statement or omission.

          (e) Actions by Registered  Holder. The Registered Holder shall, at his
     cost and expense, complete, execute and deliver all questionnaires,  powers
     of attorney, undertakings and other documents and instruments, and take all
     such other actions,  as are from time to time  reasonably  requested by the
     Company.

          (f) Survival.  The rights and obligations set forth in this Section 13
     shall survive the exercise and surrender of this Warrant.

Re:  Exercise Terms of Warrants

Gentlemen:

         Reference  is made to certain  Common Stock  purchase  warrants of U.S.
Wireless  Data,  Inc. (the  "Company")  owned by the  undersigned  and which are
exercisable  pursuant  to  their  terms  commencing  on  January  15,  1998  and
continuing  through  August 4, 2002,  to purchase up to 1,600,000  shares of the
Common  Stock of the Company at $.01 per share (the  "Warrants").  Reference  is
also made to the  Subscription  Agreements  dated as of August 4, 1997, by which
the undersigned purchased the Warrants (the "Subscription Agreements").

         The  undersigned  holders of Warrants (in the amounts set next to their
names below)  hereby agree that in  consideration  of the  Company's  efforts to
raise additional capital:

         1. The right to exercise  the  Warrants  (and  consequently  the rights
provided  pursuant to paragraph 5(a) of the  Subscription  Agreements)  shall be
deferred  until the later of: (a)  January 15,  1998;  or (b) the next Annual or
Special Meeting of the Company's shareholders,  at which the Company agrees that
it shall  submit a  proposed  amendment  to its  Articles  of  Incorporation  to
increase  the  authorized  number  of  shares  of  Common  Stock to no less than
40,000,000.  If the Company is unable to secure such increase in capital at such
meeting,  the Warrants shall become immediately  exercisable (if such meeting is
held after January 15, 1998) and the holders shall again be able to exercise the
rights provided under paragraph 5(a) of the Subscription Agreements.

         2. The holders agree that the  antidilution  provisions of the Warrants
(as set  forth in  Paragraph  8 of the  Warrants)  shall  not apply to any stock
dividends  to be paid on shares of the  Company's  Proposed  Series A Cumulative
Convertible  Redeemable  Preferred  Stock  underlying  the  8%  Adjustable  Rate
Convertible  Debentures Due December 31, 1999, which the Company is proposing to
offer within the next several weeks.


                                    Yours very truly,

                                    /s/ John M. Liviakis
                                    John L. Liviakis, as to 1,200,000 Warrants


                                    /s/ Robert B. Prag
                                    Robert B. Prag, as to 400,000 Warrants



                                                                    Exhibit 10.7

                          SHAREHOLDER VOTING AGREEMENT


         This  Shareholder  Voting  Agreement  is entered  into  effective as of
November 11, 1997, between U.S. Wireless Data, Inc., a Colorado corporation (the
"Company")  and the persons  whose names  appear on the  signature  page to this
Agreement (the "Shareholders").

                                    RECITALS

         WHEREAS,  the  Company  is  in  the  process  of  attempting  to  raise
additional capital through a private offering of Convertible Debentures;

         WHEREAS, the proposed terms of the Convertible  Debentures provide that
such  Debentures  shall be  automatically  converted  into  shares of a Series A
Preferred  Stock,  if and when such  stock is  authorized  for  issuance  by the
Company,  followed by voluntary  conversion at the behest of holders into shares
of the Company's no par value common stock (the "Common Stock");

         WHEREAS,  the Company has no preferred stock  presently  authorized for
issuance and has an insufficient  number of shares of Common Stock available (i)
to honor the conversion features of the Convertible Debentures and (ii) to honor
the obligations it has to persons holding outstanding  securities of the Company
which are convertible into shares of Common Stock;

         WHEREAS,  the  Company  intends  to hold its  1997  Annual  Meeting  of
Shareholders  (the "1997 Meeting") within the next several months,  at which the
Company will,  among other things,  submit  proposals to its shareholders for an
increase  in  authorized  Common  Stock to no less than  40,000,000  shares  and
authorize the Company to issue up to a total of  15,000,000  shares of preferred
stock  (the  "Preferred  Stock"),  with such  rights and  preferences  as may be
determined  from time to time by the Board of  Directors  of the  Company  (such
proposals to increase the number of shares of Common Stock and to authorize  the
Company to issue  Preferred  Stock being  hereafter  referred to as the "Capital
Increase Proposals");

         WHEREAS,  approval of the Capital  Increase  Proposals by  shareholders
will allow the Company (i) to honor the  obligations  it is  proposing  to enter
into with  prospective  purchasers  of the  Convertible  Debentures  and (ii) to
fulfill  its  obligations  to  holders  of its  securities  which are  presently
outstanding and convertible into shares of Common Stock; and

         WHEREAS,  in  order to  induce  potential  investors  to  purchase  the
Convertible  Debentures  and to assure that the Company has adequate  authorized
capital  stock  to honor  its  obligations  under  other  presently  outstanding
convertible  securities,  the Company has agreed to submit the Capital  Increase
Proposal to its  shareholders  at its 1997 Meeting,  and the  Shareholders  have
agreed to (i) assure that their  votable  shares are present at the 1997 Meeting
and (ii) vote those shares in favor the Capital Increase Proposals;

                                    AGREEMENT

         NOW,  THEREFORE,  in  consideration  of the mutual  promises  contained
herein,  and in order to assist the Company in raising additional capital and to
allow it to honor its obligations to presently  outstanding  securityholders  of
the Company, the undersigned Shareholders agree as follows:

         1.  Shareholder  shall  take all steps  necessary  to  assure  that all
securities  of the  Company  owned  by  the  Shareholder  either  of  record  or
beneficially, directly or indirectly, which are votable at the 1997
<PAGE>
Meeting,  or are  present and voting at such  meeting,  or any  adjournments  or
postponements thereof, either in person or by proxy.

         2.  Shareholder  shall vote such shares either in person or by proxy at
the 1997 Meeting, or any adjournments or postponements  thereof, in favor of the
Capital Increase Proposals.

         3.  This  agreement  shall  be  governed  by the  law of the  State  of
Colorado,  without regard to such State's  provisions  regarding choice of laws,
and  shall  be  binding  upon  any and  all  successors,  assignees,  executors,
receivers, trustees, custodians or pledgees of Shareholder.

         IN WITNESS  WHEREOF,  the  undersigned  Shareholder  has executed  this
Shareholder Voting Agreement effective as of the date first written above.
