                        default. Lender can then demand immediate payment of the
                        entire remaining unpaid balance of this loan, without
                        giving anyone further notice. If Borrower has not paid
                        the full amount of the Loan when due, Lender will have
                        the right to recalculate the effective annual interest
                        rate based upon 18% per annum from the original Loan

                        option or warrant in Borrower within ten (10) days
                        advance written notice by Lender to Borrower. Said
                        conversion amount will be based upon the Loan Amount
                        plus all accrued interest as outlined herein and an
                        agreed upon conversion price at the time of conversion.

<PAGE>

exchange, substitution or other event that results in a change of the number
and/or class of the securities issuable upon exercise or conversion of this
Warrant, the Holder shall be entitled to receive, upon exercise of this Warrant,
the number and kind of securities that Holder would have received if this
Warrant had been exercised immediately before the record date for such
reclassification, exchange, substitution, or other event. The Company or its

The new warrant shall provide for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Section

The provisions of this Section 2(b) shall similarly apply to successive

all of the assets of the Company,  the Company,  or such successor or purchasing

reorganization,  merger or sale, duly execute and deliver to the Holder hereof a
new  warrant so that the  Holder  shall  have the right to  receive,  at a total
purchase price not to exceed that payable upon the exercise or conversion of the
unexercised  portion  of  this  Warrant,  and  in  lieu  of the  Warrant  Shares
theretofore  issuable upon exercise or conversion of this Warrant,  the kind and
amount of shares of stock, other securities,  money and property that would have
been  receivable  upon such  reorganization,  merger or sale by the Holder  with
respect to the Warrant  Shares if this  Warrant had been  exercised  immediately
before the consummation of such transaction.  Such new warrant shall provide for

      (d) Certificate   of  Adjustment.   In  each  case  of  an  adjustment  or
readjustment of the Warrant Price, the Company, at its own expense,  shall cause
its Principal  Financial  Officer to compute such  adjustment or readjustment in
accordance  with the  provisions  hereof and prepare a certificate  showing such
adjustment  or  readjustment,  and shall mail such  certificate,  by first class
mail,  postage  prepaid,  to the Holder.  The  certificate  shall set forth such
adjustment  or  readjustment,  showing  in detail  the  facts  upon  which  such
adjustment or readjustment is based. No adjustment of the Warrant Price shall be

least one cent, but any  adjustments  not made because of this sentence shall be
carried  forward and taken into account in any subsequent  adjustment  otherwise
required hereunder.

      (e) No Impairment.  The Company  shall not, by  amendment of its  charter,
by-laws or other organizational documents, or through a reorganization, transfer
of assets, consolidation,  merger, dissolution,  issue, or sale of securities or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms to be  observed  or  performed  under  this  Warrant  by the
Company,  but shall  subject to Section 10 at all times in good faith  assist in
carrying  out all of the  provisions  of this  Section 2 and in taking  all such
action as may be necessary or appropriate  to protect the Holder's  rights under
this Section 2 against impairment.

                                      -3-
<PAGE>

      (f)  Fractional  Shares.  No  fractional  shares  shall be  issuable  upon
exercise  or  conversion  of the  Warrant  and the number of shares to be issued
shall be rounded down to the nearest whole share. If a fractional share interest
arises upon any  exercise  or  conversion  of the  Warrant,  the  Company  shall
eliminate such fractional share interest by paying the Holder an amount computed
by multiplying the fractional interest by the fair market value of a full share.

3.    No Shareholder  Rights.  This Warrant,  by itself, as  distinguished  from
any  shares  purchased  hereunder,  shall not  entitle the  Holder to any of the
rights of a shareholder of the Company.

4.    Reservation of Stock. The Company  will reserve  from its  authorized  and
unissued stock a sufficient  number of shares to provide for the issuance of the
Warrant Shares upon the exercise of this Warrant. Issuance of this Warrant shall
constitute  full  authority to the  Company's  officers who are charged with the
duty of  executing  stock  certificates  to  execute  and  issue  the  necessary
certificates for the Warrant Shares issuable upon the exercise of this Warrant.

5.    Exercise of Warrant.

      (a)  This Warrant may be exercised by the  Holder hereof,  in whole or  in
part, at any time prior to the  termination of this Warrant,  at the election of
the  Holder  hereof  (with the  notice  of  exercise  substantially  in the form
attached  hereto as Attachment 1 duly completed and executed),  by the surrender
of this Warrant at the principal office of the Company or transfer agent and the
payment to the Company,  by certified or bank check,  or by wire  transfer to an
account  designated  by the  Company of an amount  equal to the then  applicable
Warrant Price  multiplied by the number of Warrant Shares then being  purchased.
This Warrant  shall be deemed to have been  exercised  immediately  prior to the
close of business on the date of its surrender  for exercise as provided  above,
and the person  entitled  to  receive  the  Warrant  Shares  issuable  upon such
exercise  shall be treated  for all  purposes  as the  holder of such  shares of
record as of the close of  business on such date.  As  promptly  as  practicable
after such date,  the  Company  shall issue and deliver to the person or persons
entitled to receive the same a  certificate  or  certificates  for the number of
full Warrant Shares issuable upon such exercise.

      (b)  Notwithstanding anything to the contrary  contained in Section  5(a),
if the Holder elects to exercise this Warrant during the Registration Period and
at a time when a  Registration  Statement  covering  the resale by the Holder of
shares of  Common  Stock  issuable  upon the  exercise  of this  Warrant  is not
effective  or available  for use by the Holder,  the Holder may elect to receive
shares  equal  to the  value  of this  Warrant  (or the  portion  thereof  being
exercised) by surrender of this Warrant at the  principal  office of the Company
together with notice of such election  substantially in the form attached hereto
as  Attachment 1 duly  completed  and executed (a "Net  Exercise").  The Company
shall issue to a Holder who Net  Exercises a number of Warrant  Shares  computed
using the following formula:

                                    Y (A - B)
                                    ---------
                             X =        A

                                      -4-
<PAGE>

         Where

                  X =   The number of Warrant Shares to be issued to the Holder.

                  Y =   The  number  of Warrant Shares  purchasable  under  this
                        Warrant or, if  only a portion of the  Warrant is  being
                        exercised, the  portion of the  Warrant being  cancelled
                        (at the date of such calculation).

                  A =   The  fair market value of one (1) Warrant  Share (at the
                        date of such calculation).

                  B =   The Warrant Price  (as  adjusted  to the  date  of  such
                        calculation).

         For  purposes  of this  Section 5, the fair  market  value of a Warrant
Share shall mean:

         (i)      If traded on a securities exchange, the Nasdaq National Market
                  or Nasdaq SmallCap Market, the fair market value of the Common
                  Stock shall be deemed to be the average of the closing  prices
                  of the Common  Stock on such  exchange or market over the five
                  trading days immediately prior to the Determination Date;

         (ii)     If traded on the Nasdaq  Stock  Market  (other than the Nasdaq
                  National   Market  or  Nasdaq   SmallCap   Market)   or  other
                  over-the-counter  system,  the fair market value of the Common
                  Stock  shall be deemed to be the  average of the  closing  bid
                  prices  of  the  Common  Stock  over  the  five  trading  days
                  immediately prior to the Determination Date; and

                  (iii)    If there is no public  market for the  Common  Stock,
                           the fair market  value shall be the price per Warrant
                           Share that the  Company  could  obtain from a willing
                           buyer for Warrant  Shares  sold by the  Company  from
                           authorized  but  unissued  Warrant  Shares,  as  such
                           prices  shall  be  determined  in good  faith  by the
                           Company's Board of Directors.

In the event  that this  Warrant  is  exercised  pursuant  to this  Section 5 in
connection  with the  consummation  of the Company's sale of its Common Stock or
other securities  pursuant to a registration  statement under the Securities Act
of 1933, as amended (other than a registration statement relating either to sale
of  securities to employees of the Company  pursuant to its stock option,  stock
purchase or similar plan or a Rule 145 transaction) (a "Public  Offering"),  the
fair market value per Warrant Share shall be the per share offering price to the
public of the Public Offering.

6.    Optional Redemption.

      (a)  Optional  Redemption.  At any  time during  the  Optional  Redemption
Period,  the Company  shall have the right on one  occasion  only to redeem this
Warrant  in whole or in part as  provided  herein  by  payment  of the  Optional
Redemption Price pursuant to this Section 6 on the Optional  Redemption Date, so
long as the following conditions precedent are satisfied:
