This Note is issued  pursuant to the Note  Purchase  Agreement and the Holder of
this Note and this Note are subject to the terms and entitled to the benefits of
the Note Purchase Agreement.

                  The following terms shall apply to this Note:


                                    ARTICLE I

                      PAYMENT OF CERTAIN INTEREST IN COMMON
                           STOCK; OPTIONAL REDEMPTION

                  1.1 ISSUANCE OF COMMON STOCK IN LIEU OF CASH INTEREST.  (a) If
                      -------------------------------------------------
the  Company  exercises  its option to make a payment of  interest  on this Note
wholly or partly in Common Stock (herein  sometimes  called the "Share  Interest
Payment Option"),  the issuance of Interest Payment Shares upon such exercise of
the Share  Interest  Payment  Option shall have been  authorized by the Board of
Directors of the Company.

                  (b) The Company  shall not be  permitted to exercise the Share
Interest Payment Option with respect to any payment of interest on this Note if:

                  (i) the number of shares of Common Stock authorized,  unissued
         and unreserved for all purposes,  or held in the Company's treasury, is
         insufficient  to pay the portion of such  interest to be paid in Common
         Stock;

                                      -2-


                  (ii) the  issuance or delivery of Interest  Payment  Shares or
         the public resale of such Interest  Payment  Shares by the Holder would
         require  registration  or filing with or  approval of any  governmental
         authority under any law or regulation, and such registration, filing or
         approval  has not been  effected  or obtained or is not in effect or on
         such  Interest  Payment  Date or the date  the  Company  delivers  such
         Interest  Payment  Shares to the Holder the  Registration  Statement is
         unavailable  for use by the  Holder  for  the  resale  of the  Interest
         Payment  Shares or is not expected to be available  for such use for at
         least 15 Trading Days after the date the Company delivers such Interest
         Payment Shares to the Holder;

                  (iii) the  outstanding  shares of Common Stock are neither (A)
         listed or  admitted  for  trading  on a national  securities  exchange,
         Nasdaq  or  Nasdaq  SmallCap  nor (B)  quoted  on the  Over-The-Counter
         Bulletin Board; or the Interest Payment Shares shall not at the time of
         issuance (X) have been authorized for listing,  upon official notice of
         issuance,  on the  principal  securities  exchange  on which the Common
         Stock is then listed and traded or (Y) have been approved for quotation
         if then traded in the over-the-counter market;

                  (iv) the Interest Share Price for the Interest  Payment Shares
         is less than the par value of the Common Stock; or

                  (v) an Event of Default has occurred and is  continuing on the
         date the  Company  makes such  election or on the  applicable  Interest
         Payment Date.

                  (c) (1) The Company may  exercise its right to elect the Share
Interest Payment Option with respect to any Interest Payment Date only by giving
notice of such  election  to the Holder not less than 12 or more than 20 Trading
Days  prior  to such  Interest  Payment  Date,  which  notice  shall  state  the
percentage of the interest  payable on such Interest Payment Date which is to be
paid in  Interest  Payment  Shares.  If the  Company  elects the Share  Interest
Payment Option with respect to a particular  Interest  Payment Date, the Company
shall issue to the Holder in respect of such Interest Payment Date the aggregate
number of whole  shares of Common  Stock  determined  by dividing  the per share
Interest Share Price of the Common Stock on the applicable Interest Payment Date
into an amount equal to the total amount of lawful money of the United States of
America which the Holder would  receive if the  aggregate  amount of interest on
this Note  which is being paid in Common  Stock  were being paid in such  lawful
money;  PROVIDED,  HOWEVER,  that if the  Holder  has been  advised by its legal
counsel in good faith that the  payment of  interest  on a  particular  Interest
Payment Date in shares of Common Stock may give rise to liability  under Section
16(b) of the 1934 Act,  the Holder  shall have the right to elect,  by notice to
the  Company,  to defer the payment of interest


                                      -3-


on such Interest  Payment Date until the Maturity  Date and such interest  shall
continue to accrue  until the Maturity  Date or until the earlier  acceleration,
repurchase  or  conversion  of this Note in  accordance  with the terms  hereof.
Notwithstanding anything to the contrary herein, (A) if the Interest Share Price
on a particular  Interest  Payment Date is greater than 120% of the Market Price
of the Common Stock on the date the Company  gives the Holder notice that it has
elected to exercise  the Share  Interest  Payment  Option  with  respect to such
Interest Payment Date (the "Share Interest Notice Date"), the Holder may, at its
option,  require the Company to make such  payment of interest on such  Interest
Payment  Date in cash,  and (B) if the  Interest  Share  Price  on a  particular
Interest  Payment  Date is less than 80% of the Market Price of the Common Stock
on the Share Interest  Notice Date,  the Company may, at its option,  revoke its
election  of the Share  Interest  Payment  Option and pay such  interest on such
Interest Payment Date in cash.

                  (2) If the Company  elects the Share  Interest  Payment Option
with respect to an Interest  Payment Date, the Interest  Payment Shares for such
Interest  Payment Date shall become  issuable on such Interest  Payment Date and
the Company shall deliver,  or cause to be delivered,  the appropriate number of
shares  of  Common  Stock to the  Holder  within  five  Trading  Days  after the
applicable  Interest  Payment  Date.  If in any case the  Company  shall fail to
deliver or cause to be  delivered  such number of shares of Common  Stock to the
Holder  within such period of five Trading  Days,  then in addition to any other
liabilities  the Company may have  hereunder  and under  applicable  law (1) the
Company  shall pay or  reimburse  the  Holder on  demand  for all  out-of-pocket
expenses,  including, without limitation,  reasonable fees and expenses of legal
counsel,  incurred by the Holder as a result of such failure, (2) if as a result
of such failure the Holder shall suffer any direct damages or  liabilities  from
such failure  (including,  without  limitation,  margin interest and the cost of
purchasing  securities  to cover a sale  (whether by the Holder or the  Holder's
securities  broker)  or  borrowing  of shares of Common  Stock by the Holder for
purposes of settling  any trade  involving a sale of shares of Common Stock made
by the Holder during the period  beginning on the date the Company  notified the
Holder of the Company's election of the Share Interest Payment Option and ending
on the date the  Company  delivers or causes to be  delivered  to the Holder the
shares of Common Stock issuable in respect thereof), then the Company shall upon
demand of the  Holder pay to the  Holder an amount  equal to the actual  direct,
out-of-pocket  damages and liabilities  suffered by the Holder by reason thereof
which the Holder  documents to the reasonable  satisfaction of the Company,  and
(3) the  Holder  may by written  notice  (which  may be given by mail,  courier,
personal  service or  telephone  line  facsimile  transmission)  or oral  notice
(promptly  confirmed  in  writing),  given at any time prior to  delivery to the
Holder of the shares of Common Stock  issuable in connection  with such exercise
of the Share Interest Payment Option, require payment in cash of the interest in
respect of which the Company  exercised the Share Interest  Payment  Option,  in
which case the amount of such


                                      -4-


interest shall be immediately  due and payable,  with Default  Interest  thereon
from the  applicable  Interest  Payment  Date until paid in full and the Company
shall not be  obligated  or entitled to issue such  Interest  Payment  Shares in
respect of such Interest Payment Date. Notwithstanding the foregoing the Company
shall not be liable to the Holder under clause (2) of the immediately  preceding
sentence  to the extent the  failure of the Company to deliver or to cause to be
delivered  such  shares  of  Common  Stock  results  from  fire,  flood,  storm,
earthquake,   shipwreck,   strike,  war,  acts  of  terrorism,  crash  involving
facilities  of a common  carrier,  acts of God, or any similar event outside the
control of the Company (it being understood that the action or failure to act of
the  Transfer  Agent  shall not be deemed an event  outside  the  control of the
Company except to the extent  resulting  from fire,  flood,  storm,  earthquake,
shipwreck,  strike,  war, acts of  terrorism,  crash  involving  facilities of a
common  carrier,  acts of God, or any similar  event  outside the control of the
Transfer Agent or the bankruptcy,  liquidation or reorganization of the Transfer
Agent under any  bankruptcy,  insolvency or other similar law). The Holder shall
notify the  Company in  writing  (or by  telephone  conversation,  confirmed  in
writing) as promptly as  practicable  following the third Trading Day after such
Interest Payment Date if the Holder becomes aware that shares of Common Stock so
issuable have not been received as provided  herein but any failure to give such
notice shall not affect the Holder's rights under this Note or otherwise. If the
Company shall have exercised the Share Interest Payment Option with respect to a
particular  Interest  Payment  Date and either (1) the Company  shall notify the
Holder on or after such Interest  Payment Date that the Interest  Payment Shares
might not be delivered within five Trading Days after such Interest Payment Date
or (2) the Holder  learns  after the date which is five  Trading Days after such
Interest  Payment Date that the Holder has not received  such  Interest  Payment
Shares,  then,  without  releasing the Company of its  obligations  with respect
thereto,  from and after the  Trading  Day next  succeeding  the  earlier of the
events  described  in the  preceding  clauses (1) and (2) of this  sentence  the
Holder  shall make  reasonable  efforts  not to sell  shares of Common  Stock in
anticipation  of receipt of such  Interest  Payment  Shares in a manner which is
likely to increase  materially  the liability of the Company under clause (2) of
the second  preceding  sentence.  No fractional  shares of Common Stock shall be
issued in payment of interest on this Note. In lieu thereof, the Company may, at
its option,  issue a number of shares of Common Stock which  reflects a rounding
up to the next  whole  number or may pay lawful  money of the  United  States of
America in lieu of issuance of such fractional share.

                  (d) If the Company  elects the Share  Interest  Payment Option
with  respect to a payment of interest on this Note with respect to a particular
Interest  Payment Date, the Company shall deliver to the Holder,  on or prior to
the date on which  Interest  Payment Shares for such payment of interest on this
Note are to be received by the Holder, a Company  Certificate  setting forth (i)
the total amount of the cash  interest  payment to which the Holder is entitled,
(ii) the portion of such interest  payment being made in Interest Payment Shares
and the  amount  which is


                                      -5-


100%  thereof,  (iii) the number of Interest  Payment  Shares  allocable to such
payment,  as  calculated  pursuant  to  this  Section  1.1,  (iv)  any  rounding
adjustment  to such  number or any  payment  necessary  to be made  pursuant  to
Section 1.1(c),  (v) a brief  statement of the facts requiring such  adjustment,
and (vi) a brief  statement  that none of the  conditions  set forth in  Section
1.1(b) has  occurred and is existing  and that all of the  requirements  of this
Section 1.1 have been met. The Interest  Payment  Shares shall be duly issued in
the  name of the  Holder  or its  nominee.  Such  Company  Certificate  shall be
conclusive  evidence  of the  correctness  of the  calculation  of the number of
Interest  Payment  Shares  allocable  to the  payments  to  which  such  Company
Certificate  relates and of any adjustments to such number made pursuant to this
Section 1.1 in the absence of manifest error. On or before the pertinent payment
date, the Company shall issue,  or cause the transfer agent for the Common Stock
to prepare and issue,  the Interest  Payment Shares in the name of the Holder or
its nominee before being so delivered by the Company on the payment date.

                  (e) The Interest  Payment Shares,  when issued pursuant to and
in  compliance  with this Section 1.1,  shall be, and for all purposes  shall be
deemed to be,  validly  issued,  fully paid and  nonassessable  shares of Common
Stock; the issuance and delivery  thereof is in all respects hereby  authorized;
and the issuance  thereof,  together  with lawful money of the United  States of
America, if any, paid in lieu of fractional shares of Common Stock, will be, and
for all purposes  shall be deemed to be, in full discharge and  satisfaction  of
the Company's obligation to pay the interest on this Note to which such Interest
Payment Shares relate.

                  1.2 OPTIONAL  REDEMPTION.  (a) At any time during the Optional
                     ---------------------
Redemption  Period,  the Company  shall have the right to redeem at any one time
all or from time to time any part of the  outstanding  principal  amount of this
Note at the  Optional  Redemption  Price  pursuant  to this  Section  1.2 on any
Optional Redemption Date, so long as the following conditions are met:

                  (1) during a period of 20 consecutive  Trading Days ending not
         more than  three  Trading  Days prior to the date the  Company  gives a
         particular Optional Redemption Notice,

                           (A) on each such  Trading Day the Market Price of the
                  Common  Stock shall be at least 200 percent of the  Conversion
                  Price in effect on such Trading Day; and

                           (B) the Average  Daily  Trading  Volume  Threshold is
                  met;

                  (2) on the date an Optional  Redemption Notice is given and at
         all times to and including the applicable  Optional Redemption Date, no
         Event of Default and no event which, with notice or passage of time, or
         both,  would




                                      -6-



         become an Event of Default has occurred and is  continuing  (unless the
         requirements of this clause (2) will be satisfied immediately after the
         redemption of this Note on the applicable  Optional Redemption Date and
         the Company shall furnish  Company  Certificates  to the Holder to such
         effect on the date the applicable  Optional  Redemption Notice is given
         to the Holder and on the applicable Optional Redemption Date),

                  (3) on the date an Optional  Redemption Notice is given and at
         all times to and including the applicable  Optional Redemption Date, no
         Repurchase  Event has occurred with respect to which the Holder has the
         right to exercise  repurchase  rights  pursuant to Sections 4.1 and 4.2
         with respect to which the Holder has exercised such  repurchase  rights
         and the  Repurchase  Price has not been paid to the Holder and no event
         which,  with  notice  or  passage  of  time,  or both,  would  become a
         Repurchase Event has occurred and is continuing, and

                  (4) on the date the Optional Redemption Notice is given and at
         all  times   thereafter  to  and  including  the  applicable   Optional
         Redemption  Date,  the  Registration  Statement  shall be effective and
         available for use by the Holder and the holders of the Warrants for the
         resale  of  the  shares  of  Common  Stock  issued  and  issuable  upon

of this Note to be redeemed. In each such case the aggregate principal amount of

                  (b) To exercise the repurchase right, the Holder shall deliver

Repurchase Price to the Holder.

                  (c) If the Holder  shall have given a Holder  Notice,  then on

such  account as  specified by the Holder in writing to the Company at least one
Business Day prior to the applicable repurchase date.

                  4.3 OTHER. A Holder Notice given by the Holder shall be deemed
                      -----
for all  purposes to be in proper form  unless the Company  notifies  the Holder
within three Business Days after such Holder Notice has been given (which notice
shall  specify  all  defects  in such  Holder  Notice),  and any  Holder  Notice
containing  any such defect shall  nonetheless be effective on the date given if
the Holder  promptly  undertakes to correct all such  defects.  No such claim of
defect  shall  limit  or  delay


                                      -16-


performance of the Company's  obligation to repurchase any portion of this Note,
the repurchase of which is not in dispute.


                                    ARTICLE V

                                   CONVERSION

                  5.1 RIGHT TO CONVERT.  Subject to and upon compliance with the
                      ----------------
provisions  of this Note,  the Holder  shall  have the  right,  at the  Holder's
option,  at any time prior to the close of business on the Maturity Date (except
that, if the Holder shall have  exercised  repurchase  rights under Sections 4.1
and 4.2 or the Company shall have exercised its redemption  rights under Section
1.2, such  conversion  right shall terminate with respect to the portion of this
Note to be repurchased or redeemed, as the case may be, at the close of business
on the last Trading Day prior to the later of (x) the Optional  Redemption  Date
or the date the Company is required to make such repurchase, as the case may be,
and (y) the date the Company  pays or deposits in  accordance  with Section 7.10
the applicable  Repurchase Price or Optional Redemption Price unless in any such
case the Company  shall  default in payment due upon  repurchase  or  redemption
hereof) to convert  the  principal  amount of this Note,  or any portion of such
principal  amount which is at least $1,000 (or such lesser  principal  amount of
this  Note as shall be  outstanding  at such  time),  plus  accrued  and  unpaid
interest,  into that  number of fully paid and  non-assessable  shares of Common
Stock (as such shares  shall then be  constituted)  obtained by dividing (1) the
sum of (x) the principal  amount of this Note or portion thereof being converted
PLUS (y) accrued and unpaid  interest on the portion of the principal  amount of
this Note being converted to the applicable Conversion Date PLUS (z) accrued and
unpaid Default  Interest,  if any, on the amount  referred to in the immediately
preceding  clause (y) to the  applicable  Conversion  Date BY (2) the Conversion
Price in effect on the applicable Conversion Date, by giving a Conversion Notice
in the manner provided in Section 5.2; PROVIDED,  HOWEVER,  that, if at any time
this Note is  converted  in whole or in part  pursuant to this  Section 5.1, the
Company does not have available for issuance upon such  conversion as authorized
and  unissued  shares or in its treasury at least the number of shares of Common
Stock required to be issued pursuant hereto, then, at the election of the Holder
made by notice from the Holder to the Company,  this Note (or portion  hereof as
to which conversion has been requested), to the extent that sufficient shares of
Common Stock are not then  available  for  issuance  upon  conversion,  shall be
converted  into the right to receive from the Company,  in lieu of the shares of
Common  Stock into which this Note or such  portion  hereof  would  otherwise be
converted  and which the Company is unable to issue,  payment in an amount equal
to the product  obtained by multiplying (x) the number of shares of Common Stock
which the  Company is unable to issue  TIMES (y) the  arithmetic  average of the
Market  Price for the Common  Stock  during the five  consecutive


                                      -17-


Trading Days  immediately  prior to the  applicable  Conversion  Date.  Any such
payment  shall,  for all  purposes  of this  Note,  be deemed to be a payment of
principal  plus a premium  equal to the total amount  payable less the principal
portion of this Note  converted  as to which such payment is required to be made
because  shares of Common Stock are not then  available  for issuance  upon such
conversion. The Holder is not entitled to any rights of a holder of Common Stock
until the Holder has converted this Note to Common Stock, and only to the extent
this Note is deemed to have been converted to Common Stock under this Article V.
For purposes of Sections 5.5 and 5.6, whenever a provision references the shares
of Common Stock into which this Note (or a portion hereof) is convertible or the
shares of  Common  Stock  issuable  upon  conversion  of this Note (or a portion
hereof) or words of similar import, any determination required by such provision
shall be made as if a  sufficient  number of shares  of Common  Stock  were then
available for issuance upon conversion in full of this Note.

                  5.2 EXERCISE OF CONVERSION PRIVILEGE; ISSUANCE OF COMMON STOCK
                      ----------------------------------------------------------
ON CONVERSION; NO ADJUSTMENT FOR INTEREST OR DIVIDENDS. (a) In order to exercise
- ------------------------------------------------------
the  conversion  privilege  with  respect to this Note,  the Holder shall give a
Conversion  Notice (or such other notice which is  acceptable to the Company) to
the Company and the Transfer Agent or to the office or agency  designated by the
Company for such  purpose by notice to the Holder.  A  Conversion  Notice may be
given by telephone line facsimile  transmission  to the numbers set forth on the
form of Conversion Notice.

                  (b) As  promptly  as  practicable,  but in no event later than
five Trading Days,  after a Conversion  Notice is given, the Company shall issue
and shall  deliver to the  Holder or the  Holder's  designee  the number of full
shares of Common Stock  issuable  upon such  conversion  of this Note or portion
hereof in accordance  with the provisions of this Article and deliver a check or
cash in respect of any fractional interest in respect of a share of Common Stock
arising upon such conversion,  as provided in Section 5.2(f) and, if applicable,
any cash  payment  required  pursuant  to the  proviso to the first  sentence of
Section 5.1 (which  payment,  if any,  shall be paid no later than five  Trading
Days after the applicable Conversion Date).

                  (c) Each  conversion of this Note (or portion hereof) shall be
deemed to have been effected on the applicable  Conversion  Date, and the person
in whose name any certificate or  certificates  for shares of Common Stock shall
be  issuable  upon  such  conversion  shall be  deemed  to have  become  on such
Conversion  Date  the  holder  of  record  of the  shares  represented  thereby;
PROVIDED,  HOWEVER,  that if a  Conversion  Date is a date on  which  the  stock
transfer books of the Company shall be closed such conversion  shall  constitute
the person in whose name the  certificates are to be issued as the record holder
thereof for all purposes on the next succeeding day on which such stock transfer
books are open, but such conversion  shall be at the


                                      -18-


Conversion Price in effect on the applicable Conversion Date. Upon conversion of
this Note or any portion  hereof,  the accrued and unpaid  interest on this Note
(or portion hereof) to (but  excluding) the applicable  Conversion Date shall be
deemed to be paid to the Holder of this Note  through  receipt of such number of
shares of Common Stock issued upon  conversion of this Note or portion hereof as
shall have an aggregate Current Fair Market Value on the Trading Day immediately
preceding  such  Conversion  Date equal to the amount of such accrued and unpaid
interest.

                  (d) The  Company  shall  notify the Holder of any claim by the
Company of manifest  error in a Conversion  Notice within two Trading Days after
the Holder gives such  Conversion  Notice and no such claim of error shall limit
or delay  performance of the Company's  obligation to issue upon such conversion
the number of shares of Common  Stock  which are not in  dispute.  A  Conversion
Notice  shall be deemed for all purposes to be in proper form unless the Company
notifies the Holder by telephone line facsimile  transmission within two Trading
Days after a  Conversion  Notice has been given  (which  notice from the Company
shall specify all defects in the Conversion  Notice) and any  Conversion  Notice
containing  any such defect shall  nonetheless be effective on the date given if
the Holder  promptly  undertakes to correct all such defects.  The Company shall
not be required  to pay any tax which may be payable in respect of any  transfer
involved  in the  issuance  and  delivery  of shares  of  Common  Stock or other
securities  or property on  conversion of this Note in a name other than that of
the Holder,  and the Company  shall not be required to issue or deliver any such
shares or other  securities  or property  unless and until the person or persons
requesting the issuance thereof shall have paid to the Company the amount of any
such tax or shall have  established to the satisfaction of the Company that such
tax has been  paid.  The  Holder  shall be  responsible  for the  amount  of any
withholding tax payable in connection with any conversion of this Note.

                  (e) (1) If the Holder shall have given a Conversion  Notice in
accordance  with the terms of this Note,  the Company's  obligation to issue and
deliver the certificates  for Common Stock shall be absolute and  unconditional,
irrespective  of any action or inaction  by the Holder to enforce the same,  any
waiver or consent  with  respect to any  provision  hereof,  the recovery of any
judgment  against any person or any action to enforce  the same,  any failure or
delay in the  enforcement of any other  obligation of the Company to the Holder,
or any setoff,  counterclaim,  recoupment,  limitation  or  termination,  or any
breach or alleged  breach by the Holder or any other person of any obligation to
the Company or any  violation  or alleged  violation of law by the Holder or any
other person,  and irrespective of any other  circumstance which might otherwise
limit such  obligation  of the  Company to the  Holder in  connection  with such
conversion;  PROVIDED, HOWEVER, that nothing herein shall limit or prejudice the
right of the Company to pursue any such claim in any other  manner  permitted by
applicable  law. The



                                      -19-


occurrence of an event which requires an adjustment of the  Conversion  Price as
contemplated  by Section 5.3 shall in no way  restrict or delay the right of the
Holder to receive certificates for Common Stock upon conversion of this Note and
the Company  shall use its best efforts to implement  such  adjustment  on terms
reasonably acceptable to the Holder within two Trading Days of such occurrence.

                  (2) If in any case the Company shall fail to issue and deliver
the  shares  of  Common  Stock to the  Holder in  connection  with a  particular
conversion  of this Note within  five  Trading  Days after the Holder  gives the
Conversion Notice for such conversion,  in addition to any other liabilities the
Company may have hereunder and under applicable law (A) the Company shall pay or
reimburse  the  Holder  on demand  for all  out-of-pocket  expenses,  including,
without limitation,  reasonable fees and expenses of legal counsel,  incurred by
the Holder as a result of such  failure,  (B) if as a result of such failure the
Holder  shall  suffer  any  direct  damages  or  liabilities  from such  failure
(including,  without  limitation,  margin  interest  and the cost of  purchasing
securities  to cover a sale  (whether by the Holder or the  Holder's  securities
broker) or  borrowing  of shares of Common  Stock by the Holder for  purposes of
settling any trade involving a sale of shares of Common Stock made by the Holder
during  the period  beginning  on the  Issuance  Date and ending on the date the
Company  delivers or causes to be  delivered to the Holder such shares of Common
Stock),  then the  Company  shall upon demand of the Holder pay to the Holder an
amount  equal  to the  actual  direct,  out-of-pocket  damages  and  liabilities
suffered  by the  Holder by reason  thereof  which the Holder  documents  to the
reasonable satisfaction of the Company, and (C) the Holder may by written notice
(which  may be  given by mail,  courier,  personal  service  or  telephone  line
facsimile transmission) or oral notice (promptly confirmed in writing), given at
any time prior to delivery to the Holder of the shares of Common Stock  issuable
in connection with such exercise of the Holder's conversion right,  rescind such
exercise and the Conversion  Notice relating  thereto,  in which case the Holder
shall  thereafter  be entitled to convert  that portion of this Note as to which
such exercise is so rescinded and to exercise its other rights and remedies with
respect to such  failure  by the  Company.  Notwithstanding  the  foregoing  the
Company  shall not be liable to the Holder under  clause (B) of the  immediately
preceding  sentence  to the extent the  failure of the  Company to deliver or to
cause to be  delivered  such shares of Common Stock  results  from fire,  flood,
storm, earthquake,  shipwreck,  strike, war, acts of terrorism,  crash involving
facilities  of a common  carrier,  acts of God, or any similar event outside the
control of the Company (it being understood that the action or failure to act of
the  Transfer  Agent  shall not be deemed an event  outside  the  control of the
Company except to the extent  resulting  from fire,  flood,  storm,  earthquake,
shipwreck,  strike,  war, acts of  terrorism,  crash  involving  facilities of a
common  carrier,  acts of God, or any similar  event  outside the control of the
Transfer Agent or the bankruptcy,  liquidation or reorganization of the Transfer
Agent under any  bankruptcy,  insolvency or other similar law). The Holder shall
notify the  Company in  writing  (or by  telephone  conversation,  confirmed  in
writing) as


                                      -20-


promptly as practicable following the fifth Trading Day after the Holder gives a
Conversion  Notice if the Holder  becomes aware that such shares of Common Stock
so issuable  have not been  received as provided  herein,  but any failure so to
give such  notice  shall not  affect  the  Holder's  rights  under  this Note or
otherwise.  If the  Holder  shall have  exercised  the  conversion  right in any
particular  instance  and either (1) the Company  shall  notify the Holder on or
after such that the shares of Common Stock issuable upon such  conversion  might
not be  delivered  within five Trading Days after the date the Holder gives such
Conversion  Notice or (2) the Holder learns after the date which is five Trading
Days after the date the Holder gives such Conversion  Notice that the Holder has
not received such shares of Common Stock, then, without releasing the Company of
its  obligations  with  respect  thereto,  from and after the  Trading  Day next
succeeding the earlier of the events described in the preceding  clauses (1) and
(2) of this sentence the Holder shall make reasonable efforts not to sell shares
of Common Stock in  anticipation  of receipt of such shares of Common Stock in a
manner which is likely to increase materially the liability of the Company under
clause (2) of the second preceding sentence.

                  (f) No fractional  shares of Common Stock shall be issued upon
conversion  of this Note but, in lieu of any fraction of a share of Common Stock
which would otherwise be issuable in respect of such conversion, the Company may
round the number of shares of Common Stock issued on such  conversion  up to the
next highest whole share or may pay lawful money of the United States of America
for such fractional  share,  based on a value of one share of Common Stock being
equal to the Market Price of the Common Stock on the applicable Conversion Date.

                  5.3 ADJUSTMENT OF CONVERSION PRICE. The Conversion Price shall
                      ------------------------------
be adjusted from time to time by the Company as follows:

                  (a) In case the Company  shall on or after the  Issuance  Date
pay a dividend or make a distribution to all holders of the  outstanding  Common
Stock in shares of Common Stock,  the Conversion  Price in effect at the opening
of  business  on the date  following  the date  fixed for the  determination  of
stockholders  entitled to receive such dividend or other  distribution  shall be
reduced  by  multiplying  such  Conversion  Price by a  fraction  of  which  the
numerator shall be the number of shares of Common Stock outstanding at the close
of business on the Record Date fixed for such  determination and the denominator
shall be the sum of such  number  of  shares  and the  total  number  of  shares
constituting  such  dividend or other  distribution,  such  reduction  to become
effective  immediately  after the opening of business on the day  following  the
Record  Date.  If any  dividend or  distribution  of the type  described in this
Section 5.3(a) is declared but not so paid or made,  the Conversion  Price shall
again be adjusted to the Conversion  Price which would then be in effect if such
dividend or distribution had not been declared.

                                      -21-


                  (b) In case the Company  shall on or after the  Issuance  Date
issue  rights or  warrants  (other  than any rights or  warrants  referred to in
Section  5.3(d))  to all  holders  of its  outstanding  shares of  Common  Stock
entitling  them (for a period  expiring  within 45 days after the date fixed for
the  determination of stockholders  entitled to receive such rights or warrants)
to  subscribe  for or purchase  shares of Common Stock at a price per share less
than the Current Market Price on the Record Date fixed for the  determination of
stockholders  entitled to receive such rights or warrants,  the Conversion Price
shall  be  adjusted  so that  the same  shall  equal  the  price  determined  by
multiplying  the  Conversion  Price in effect at the  opening of business on the
date after such Record Date by a fraction  of which the  numerator  shall be the
number of shares of Common  Stock  outstanding  at the close of  business on the
Record Date plus the number of shares which the aggregate  offering price of the
total number of shares so offered would  purchase at such Current  Market Price,
and the denominator shall be the number of shares of Common Stock outstanding on
the close of  business on the Record  Date plus the total  number of  additional
shares of Common Stock so offered for subscription or purchase.  Such adjustment
shall  become  effective  immediately  after the  opening of business on the day
following the Record Date fixed for  determination  of stockholders  entitled to
receive such rights or  warrants.  To the extent that shares of Common Stock are
not  delivered  pursuant  to such rights or  warrants,  upon the  expiration  or
termination of such rights or warrants, the Conversion Price shall be readjusted
to the Conversion  Price which would then be in effect had the adjustments  made
upon the issuance of such rights or warrants  been made on the basis of delivery
of only the number of shares of Common Stock  actually  delivered.  In the event
that such rights or warrants are not so issued, the Conversion Price shall again
be  adjusted  to be the  Conversion  Price which would then be in effect if such
date fixed for the determination of stockholders entitled to receive such rights
or warrants had not been fixed.  In  determining  whether any rights or warrants
entitle the holder to subscribe  for or purchase  shares of Common Stock at less
than such Current Market Price, and in determining the aggregate  offering price
of such  shares  of  Common  Stock,  there  shall  be  taken  into  account  any
consideration   received  for  such  rights  or  warrants,  the  value  of  such
consideration, if other than cash, to be determined by the Board of Directors.

                  (c) In case the outstanding shares of Common Stock shall on or
after the Issuance Date be subdivided  into a greater number of shares of Common
Stock,  the Conversion Price in effect at the opening of business on the earlier
of the day following the day upon which such subdivision  becomes  effective and
the day on which "ex-"  trading of the Common  Stock begins with respect to such
subdivision  shall  be  proportionately   reduced,   and  conversely,   in  case
outstanding  shares of Common Stock shall be combined  into a smaller  number of
shares of Common  Stock,  the  Conversion  Price in  effect  at the  opening  of
business on the earlier of the day following the day upon which such combination
becomes  effective  and the day on which "ex-"  trading of the Common Stock with
respect to such  combination


                                      -22-


begins shall be proportionately  increased,  such reduction or increase,  as the
case may be, to become  effective  immediately  after the opening of business on
the  earlier  of the day  following  the day  upon  which  such  subdivision  or
combination  becomes  effective and the day on which "ex-" trading of the Common
Stock begins with respect to such subdivision or combination.

                  (d) In case the Company  shall on or after the Issuance  Date,
by dividend or  otherwise,  distribute to all holders of its Common Stock shares
of any class of  capital  stock of the  Company  (other  than any  dividends  or
distributions to which Section 5.3(a) applies) or evidences of its indebtedness,
cash or other assets (including securities, but excluding any rights or warrants
referred to in Section 5.3(b) and dividends and  distributions  paid exclusively
in cash and  excluding any capital  stock,  evidences of  indebtedness,  cash or
assets  distributed upon a merger or consolidation to which Section 5.4 applies)
(the foregoing  hereinafter  in this Section  5.3(d) called the  "Securities")),
then, in each such case, subject to the second paragraph of this Section 5.3(d),
the  Conversion  Price  shall be  reduced so that the same shall be equal to the
price determined by multiplying the Conversion Price in effect immediately prior
to the close of business on the Record Date with respect to such distribution by
a fraction of which the numerator shall be the Current Market Price on such date
less the fair  market  value (as  determined  by the Board of  Directors,  whose
determination  shall be conclusive and described in a Board  Resolution) on such
date of the portion of the Securities so distributed  applicable to one share of
Common  Stock and the  denominator  shall be such  Current  Market  Price,  such
reduction to become  effective  immediately  prior to the opening of business on
the day following the Record Date; PROVIDED, HOWEVER, that in the event the then
fair  market  value (as so  determined)  of the  portion  of the  Securities  so
distributed  applicable to one share of Common Stock is equal to or greater than
the  Current  Market  Price  on the  Record  Date,  in  lieu  of  the  foregoing
adjustment,  adequate  provision shall be made so that the Holder shall have the
right to receive upon conversion of this Note (or any portion hereof) the amount
of  Securities  such holder would have received had such holder  converted  this
Note (or portion  hereof)  immediately  prior to such Record Date.  In the event
that such dividend or distribution is not so paid or made, the Conversion  Price
shall again be adjusted to be the Conversion Price which would then be in effect
if such  dividend  or  distribution  had not  been  declared.  If the  Board  of
Directors  determines the fair market value of any  distribution for purposes of
this Section 5.3(d) by reference to the actual or when issued trading market for
any Securities comprising all or part of such distribution,  it must in doing so
consider  the prices in such market over the same period used in  computing  the
Current Market Price, to the extent possible.

                  Rights or warrants  distributed  by the Company to all holders
of Common  Stock  entitling  the holders  thereof to  subscribe  for or purchase
shares  of the  Company's  capital  stock  (either  initially  or under  certain
circumstances),  which rights or warrants,  until the  occurrence of a specified
event or events (a "Trigger


                                      -23-


Event"): (i) are deemed to be transferred with such shares of Common Stock; (ii)
are not exercisable; and (iii) are also issued in respect of future issuances of
Common Stock,  shall not be deemed to have been distributed for purposes of this
Section 5.3 (and no  adjustment to the  Conversion  Price under this Section 5.3
will be required)  until the occurrence of the earliest  Trigger  Event.  If any
such  rights  or  warrants,  including  any such  existing  rights  or  warrants
distributed prior to the Issuance Date, are subject to Trigger Events,  upon the
satisfaction  of each of which such rights or warrants shall become  exercisable
to purchase  different  securities,  evidences of  indebtedness or other assets,
then the  occurrence  of each such Trigger Event shall be deemed to be such date
of  issuance  and record  date with  respect to new  rights or  warrants  (and a
termination or expiration of the existing rights or warrants without exercise by
the holder  thereof) (so that, by way of illustration  and not  limitation,  the
dates of issuance  of any such  rights  shall be deemed to be the dates on which
such rights become exercisable to purchase capital stock of the Company, and not
the date on which such rights may be issued, or may become evidenced by separate
certificates,  if such rights are not then so exercisable).  In addition, in the
event of any  distribution  of rights or  warrants,  or any  Trigger  Event with
respect  thereto,  that was counted for purposes of  calculating a  distribution
amount for which an  adjustment to the  Conversion  Price under this Section 5.3
was made (1) in the case of any such  rights or  warrants  which  shall all have
been  redeemed or  repurchased  without  exercise by any  holders  thereof,  the
Conversion Price shall be readjusted upon such final redemption or repurchase to
give effect to such distribution or Trigger Event, as the case may be, as though
it were a cash  distribution,  equal to the per share  redemption  or repurchase
price  received  by a holder or  holders of Common  Stock  with  respect to such
rights or warrants  (assuming such holder had retained such rights or warrants),
made to all  holders  of  Common  Stock  as of the  date of such  redemption  or
repurchase,  and (2) in the case of such  rights or  warrants  which  shall have
expired  or  been  terminated  without  exercise  by any  holders  thereof,  the
Conversion Price shall be readjusted as if such rights and warrants had not been
issued.

                  For  purposes of this Section  5.3(d) and Sections  5.3(a) and
(b), any dividend or  distribution  to which this Section  5.3(d) is  applicable
that also includes  shares of Common  Stock,  or rights or warrants to subscribe
for or  purchase  shares of Common  Stock to which  Section  5.3(b)  applies (or
both),  shall be deemed  instead to be (1) a  dividend  or  distribution  of the
evidences of indebtedness,  assets,  shares of capital stock, rights or warrants
other than such shares of Common  Stock or rights or  warrants to which  Section
5.3(b)  applies (and any  Conversion  Price  reduction  required by this Section
5.3(d)  with  respect  to such  dividend  or  distribution  shall  then be made)
immediately  followed by (2) a dividend or distribution of such shares of Common
Stock or such rights or warrants  (and any further  Conversion  Price  reduction
required  by  Sections   5.3(a)  and  (b)  with  respect  to  such  dividend  or
distribution shall then be made), except (A) the Record Date of such dividend or
distribution  shall be substituted as "the date fixed for the  determination  of

                                      -24-


stockholders  entitled to receive such dividend or other distribution",  "Record
Date fixed for such  determination"  and  "Record  Date"  within the  meaning of
Section  5.3(a) and as "the date  fixed for the  determination  of  stockholders
entitled  to receive  such rights or  warrants",  "the Record Date fixed for the
determination of the  stockholders  entitled to receive such rights or warrants"
and "such Record  Date" within the meaning of Section  5.3(b) and (B) any shares
of Common Stock  included in such dividend or  distribution  shall not be deemed
"outstanding  at the  close  of  business  on the  Record  Date  fixed  for such
determination" within the meaning of Section 5.3(a).

                  (e) In case the Company  shall on or after the Issuance  Date,
by dividend or  otherwise,  distribute  to all holders of its Common  Stock cash
(excluding any cash that is distributed  upon a merger or consolidation to which
Section 5.4 applies or as part of a distribution  referred to in Section 5.3(d))
in an aggregate amount that, combined with (1) the aggregate amount of any other
such  distributions  to all holders of its Common Stock made exclusively in cash
within the 12 months preceding the date of payment of such distribution,  and in
respect of which no  adjustment  pursuant to this Section  5.3(e) has been made,
and (2) the  aggregate of any cash plus the fair market value (as  determined by
the Board of Directors, whose determination shall be conclusive and set forth in
a Board  Resolution) of consideration  payable in respect of any Tender Offer by
the  Company  or any  Subsidiary  for all or any  portion  of the  Common  Stock
concluded   within  the  12  months  preceding  the  date  of  payment  of  such
distribution,  and in respect of which no adjustment  pursuant to Section 5.3(f)
has been made, exceeds 10% of the product of (x) the Current Market Price on the
Record Date with respect to such distribution  TIMES (y) the number of shares of
Common Stock outstanding on such date, then, and in each such case,  immediately
after the close of business on such date,  unless the Company  elects to reserve
such cash for  distribution  to the Holder upon the conversion of this Note (and
shall have made  adequate  provision)  so that the Holder will receive upon such
conversion,  in  addition  to the shares of Common  Stock to which the Holder is
entitled,  the amount of cash which the Holder would have received if the Holder
had,  immediately  prior  to the  Record  Date for  such  distribution  of cash,
converted this Note into Common Stock,  the Conversion Price shall be reduced so
that the same shall equal the price  determined by  multiplying  the  Conversion
Price in effect  immediately  prior to the close of business on such Record Date
by a fraction (i) the  numerator  of which shall be equal to the Current  Market
Price on the Record Date less an amount  equal to the quotient of (x) the excess
of such  combined  amount  over such 10% and (y) the  number of shares of Common
Stock  outstanding on the Record Date and (ii) the denominator of which shall be
equal to the Current Market Price on the Record Date; PROVIDED, HOWEVER, that in
the event the  portion  of the cash so  distributed  applicable  to one share of
Common Stock is equal to or greater than the Current  Market Price of the Common
Stock  on the  Record  Date,  in  lieu  of the  foregoing  adjustment,  adequate
provision  shall be made so that the Holder shall have the right to receive upon
conversion  of


                                      -25-


this Note (or any  portion  hereof)  the  amount of cash the  Holder  would have
received  had the Holder  converted  this Note (or portion  hereof)  immediately
prior to such Record Date.  In the event that such dividend or  distribution  is
not so paid or made,  the  Conversion  Price  shall  again be adjusted to be the
Conversion  Price which would then be in effect if such dividend or distribution
had not been declared.

                  (f) In case a Tender Offer on or after the Issuance  Date made
by the  Company or any  Subsidiary  for all or any  portion of the Common  Stock
shall  expire and such Tender  Offer (as amended  upon the  expiration  thereof)
shall require the payment to  stockholders  (based on the  acceptance (up to any
maximum  specified  in the terms of the Tender  Offer) of  Purchased  Shares (as
defined  below)) of an  aggregate  consideration  having a fair market value (as
determined by the Board of Directors,  whose  determination  shall be conclusive
and  described  in a Board  Resolution)  that  combined  together  with  (1) the
aggregate of the cash plus the fair market value (as  determined by the Board of
Directors,  whose  determination  shall be  conclusive  and described in a Board
Resolution), as of the expiration of such Tender Offer, of consideration payable
in respect of any other Tender Offers,  by the Company or any Subsidiary for all
or any portion of the Common Stock expiring  within the 12 months  preceding the
expiration of such Tender Offer and in respect of which no  adjustment  pursuant
to this  Section  5.3(f)  has been  made  and (2) the  aggregate  amount  of any
distributions  to all holders of the Company's  Common Stock made exclusively in
cash within 12 months  preceding  the  expiration  of such  Tender  Offer and in
respect of which no adjustment pursuant to Section 5.3(e) has been made, exceeds
10% of the  product  of (i) the  Current  Market  Price as of the last time (the
"Expiration  Time")  tenders  could have been made pursuant to such Tender Offer
(as it may be  amended)  TIMES  (ii)  the  number  of  shares  of  Common  Stock
outstanding (including any tendered shares) at the Expiration Time, then, and in
each such case,  immediately  prior to the  opening of business on the day after
the date of the Expiration  Time, the Conversion Price shall be adjusted so that
the same shall equal the price determined by multiplying the Conversion Price in
effect immediately prior to close of business on the date of the Expiration Time
by a  fraction  of which the  numerator  shall be the number of shares of Common
Stock  outstanding  (including  any  tendered  shares)  at the  Expiration  Time
multiplied  by the Current  Market  Price of the Common Stock on the Trading Day
next succeeding the Expiration Time and the denominator  shall be the sum of (x)
the fair market value  (determined as aforesaid) of the aggregate  consideration
payable to stockholders  based on the acceptance (up to any maximum specified in
the terms of the Tender Offer) of all shares validly  tendered and not withdrawn
as of the  Expiration  Time  (the  shares  deemed  so  accepted,  up to any such
maximum, being referred to as the "Purchased Shares") and (y) the product of the
number of shares of Common Stock  outstanding (less any Purchased Shares) at the
Expiration  Time and the Current Market Price of the Common Stock on the Trading
Day next  succeeding  the  Expiration  Time,  such  reduction (if any) to become
effective  immediately prior to the opening of business on the day following the
Expiration


                                      -26-


Time. In the event that the Company is obligated to purchase  shares pursuant to
any such Tender Offer,  but the Company is  permanently  prevented by applicable
law from effecting any such  purchases or all such purchases are rescinded,  the
Conversion  Price shall again be adjusted to be the Conversion Price which would
then be in effect if such Tender Offer had not been made. If the  application of
this  Section  5.3(f) to any Tender  Offer  would  result in an  increase in the
Conversion  Price, no adjustment  shall be made for such Tender Offer under this
Section 5.3(f).

                  (g) (1) In case at any time on or after the Issuance  Date the
Company  shall  issue  shares of its Common  Stock or Common  Stock  Equivalents
(collectively,  the "Newly Issued  Shares"),  other than an issuance pro rata to
all  holders  of its  outstanding  Common  Stock and other than an  issuance  in
respect of which Section 5.3(h) is applicable, at a price below the Current Fair
Market Value of the Common Stock at the time of such  issuance,  then  following
such issuance of Newly Issued Shares the  Conversion  Price shall be adjusted as
provided  in this  Section  5.3(g).  The  Conversion  Price  following  any such
adjustment shall be determined by multiplying the Conversion  Price  immediately
prior to such adjustment by a fraction,  of which the numerator shall be the sum
of (a) the number of shares of Common Stock outstanding immediately prior to the
issuance  of the  Newly  Issued  Shares  (calculated  on a  fully-diluted  basis
assuming the conversion of all options, warrants, purchase rights or convertible
securities which are exercisable at the time of the issuance of the Newly Issued
Shares)  PLUS (b) the  number  of shares of  Common  Stock  which the  aggregate
consideration,  if any,  received by the Company for the number of Newly  Issued
Shares  would  purchase at a price equal to the Current Fair Market Value of the
Common Stock at the time of such issuance,  and the denominator shall be the sum
of (X) the number of shares of Common Stock outstanding immediately prior to the
issuance  of the  Newly  Issued  Shares  (calculated  on a  fully-diluted  basis
assuming the exercise or conversion of all options, warrants, purchase rights or
convertible  securities  which are exercisable or convertible at the time of the
issuance of the Newly Issued Shares) PLUS (Y) the number of Newly Issued Shares.
The  adjustment  provided  for in this  Section  5.3(g) may be  expressed as the
following mathematical formula:

                              ( O +(C / FMV)) x CP
                              ---------------
                      NCP =   (  O  +  N  )
where:

         C        =   aggregate consideration received by the Company for the
                      Newly Issued Shares

         N        =   number of Newly Issued Shares

                                      -27-


         O        =   number of shares of Common Stock  outstanding  (on a fully
                      diluted basis, as described above)immediately prior to the
                      issuance of the Newly Issued Shares

         FMV      =   Current Fair Market Value of the Common  Stock at the time
                      of issuance of the Newly Issued Shares

         CP       =   Conversion Price immediately prior to the issuance of the
                      Newly Issued Shares

         NCP      =   Conversion  Price  immediately  after the  issuance of the
                      Newly Issued Shares

                  (2) Notwithstanding  the  foregoing,  no adjustment  shall  be
                      made under this Section 5.3(g) by reason of:

                  (A) the  issuance by the Company of shares of Common Stock pro
rata to all  holders of the Common  Stock so long as (i) any  adjustment  to the
Conversion Price that is required by Section 5.3(a) is made and (ii) the Company
shall have given  notice of such  issuance  thereof  to the Holder  pursuant  to
Section 5.6;

                  (B) the issuance by the Company of the Notes, the Other Notes,
the Warrants or the Other Warrants or shares of Common Stock upon  conversion of
this Note,  or the Other  Notes or upon  exercise  of the  Warrants or the Other
Warrants  or in  accordance  with the  terms  hereof  and  thereof  or any other
issuance of  securities  solely to the Holder  occurring on or before August 31,
2004;

                  (C) the  issuance by the Company of shares of Common  Stock in
payment of interest on this Note in accordance with the terms hereof;

                  (D) the issuance of Common Stock upon conversion,  exercise or
exchange of Common Stock Equivalents outstanding on the Issuance Date;

                  (E) the  issuance by the Company of Newly  Issued  Shares upon
grant or exercise of options for employees,  directors and  consultants  under a
stock option,  equity  compensation or similar plan duly adopted by the Board of
Directors; or

                  (F) the  issuance by the Company of the  Advance  Shares,  the
Advance  Warrants or the Placement Agent Warrants or shares of Common Stock upon
exercise of the Advance  Warrants or the Placement  Agent Warrants in accordance
with the terms hereof and thereof.

                                      -28-


                  (h) (1) In case at any time on or before  January  8, 2005 the
Company issues shares of Common Stock or Common Stock  Equivalents  that are not
registered for sale by the Company in such offering under the 1933 Act or issues
shares of Common  Stock or Common  Stock  Equivalents  in an  offering of a type
commonly known as a PIPE or an equity line, in any such case in an amount which,
together with all other  offerings by the Company that would be integrated  with
such offering for purposes of Regulation D under the 1933 Act,  results in gross
proceeds to the Company of at least $250,000,  at a price per share at which the
Company  sells such  shares of Common  Stock or the price per share at which the
holders of such Common  Stock  Equivalents  are  entitled  to acquire  shares of
Common  Stock  upon  conversion  or  exercise  thereof  which  is less  than the
Conversion  Price in effect at the time of such  issuance,  then  following such
issuance  the  Conversion  Price  shall be  reduced  to the  price per share (or
weighted  average  price per share,  if such shares are  issued,  or such Common
Stock  Equivalents may be converted or exercised,  at different prices) at which
such shares of Common Stock are issued or at which such Common Stock Equivalents
may be  exercised,  if the same is lower  than the  Conversion  Price in  effect
immediately prior to such issuance.

                  (2) If any adjustment in the Conversion Price is made pursuant
to this  Section  5.3(h) in respect of any issuance of shares of Common Stock or
Common Stock Equivalents, no adjustment in the Conversion Price shall be made by
reason of such issuance pursuant to Section 5.3(g).

                  (3) Notwithstanding the foregoing, no adjustment shall be made
under this Section 5.3(h) by reason of:

                  (A) the  issuance by the Company of shares of Common Stock pro
rata to all holders of the Common Stock so long as (i) any  adjustment  required
by Section  5.3(a) is made and (ii) the Company shall have given notice  thereof
to the Holder pursuant to Section 5.6;

                  (B) the issuance by the Company of the Notes, the Other Notes,
the  Warrants or the Other  Warrants or the issuance by the Company of shares of
Common Stock upon conversion of this Note or the Other Notes or upon exercise of
the  Warrants or the Other  Warrants  in  accordance  with the terms  hereof and
thereof or any other issuance of securities solely to the Holder occurring on or
before August 31, 2004;

                  (C) the  issuance by the Company of shares of Common  Stock in
payment of interest on this Note or the Other Notes in accordance with the terms
hereof and thereof;

                                      -29-


                  (D) the issuance of Common Stock upon conversion,  exercise or
exchange of Common Stock Equivalents outstanding on the Issuance Date; or

                  (E) the  issuance by the Company of Newly  Issued  Shares upon
grant or exercise of options for employees,  directors and  consultants  under a
stock option,  equity  compensation or similar plan duly adopted by the Board of
Directors; or

                  (F) the  issuance by the Company of the  Advance  Shares,  the
Advance  Warrants or the Placement Agent Warrants or shares of Common Stock upon
exercise of the Advance  Warrants or the Placement  Agent Warrants in accordance
with the terms hereof and thereof.

                  (i) The Company  may make such  reductions  in the  Conversion
Price,  in addition to those  required by Sections  5.3(a),  (b), (c), (d), (e),
(f), (g) and (h), as the Board of  Directors  considers to be advisable to avoid
or  diminish  any income tax to  holders of Common  Stock or rights to  purchase
Common Stock  resulting from any dividend or distribution of stock (or rights to
acquire stock) or from any event treated as such for income tax purposes.

                  (j) No  adjustment in the  Conversion  Price shall be required
unless such  adjustment  would require an increase or decrease of at least 1% in
such price;  PROVIDED,  HOWEVER,  that any  adjustments  which by reason of this
Section  5.3(j) are not  required to be made shall be carried  forward and taken
into account in any subsequent adjustment. All calculations under this Article V
shall be made by the  Company  and shall be made to the  nearest  cent or to the
nearest one hundredth of a share, as the case may be.

No adjustment  need be made for a change in the par value of the Common Stock or
from par value to no par value or from no par value to par value.

                  (k)  Whenever  the  Conversion  Price is  adjusted  as  herein
provided,  the  Company  shall  promptly,  but in no event  later than five days
thereafter, give a notice to the Holder setting forth the Conversion Price after
such  adjustment and setting forth a brief statement of the facts requiring such
adjustment, but which statement shall not include any information which would be
material non-public information for purposes of the 1934 Act. Failure to deliver
such notice shall not affect the legality or validity of any such adjustment.

                  (l) In any case in which this  Section  5.3  provides  that an
adjustment shall become effective  immediately after a Record Date for an event,
the  Company  may defer  until the  occurrence  of such event (i) issuing to the
Holder in connection with any conversion of this Note after such Record Date and
before  the  occurrence  of such  event the  additional  shares of Common  Stock
issuable upon such


                                      -30-


conversion by reason of the adjustment required by such event over and above the
Common  Stock  issuable  upon  such  conversion  before  giving  effect  to such
adjustment  and (ii)  paying to such  holder  any  amount in cash in lieu of any
fraction pursuant to Section 5.2(f).

                  (m) For  purposes of this Section 5.3, the number of shares of
Common  Stock at any time  outstanding  shall  not  include  shares  held in the
treasury of the Company but shall  include  shares  issuable in respect of scrip
certificates  issued in lieu of fractions of shares of Common Stock. The Company
will not pay any  dividend or make any  distribution  on shares of Common  Stock
held in the  treasury  of the  Company  other than  dividends  or  distributions
payable only in shares of Common Stock.

5.4    EFFECT   OF    RECLASSIFICATION,    CONSOLIDATION,    MERGER   OR   SALE.
       --------------------------------------------------  (a)  If  any  of  the
following  events  occur,  namely  (i) any  reclassification  or  change  of the
outstanding  shares of Common Stock  (other than a change in par value,  or from
par value to no par value,  or from no par value to par value, or as a result of
a subdivision or combination), (ii) any consolidation,  merger or combination of
the Company  with  another  corporation  as a result of which  holders of Common
Stock shall be entitled to receive stock, securities or other property or assets
(including  cash) with respect to or in exchange for such Common Stock, or (iii)
any sale or  conveyance  of the  properties  and  assets of the  Company  as, or
substantially  as, an  entirety  to any other  corporation  as a result of which
holders of Common Stock shall be entitled to receive stock,  securities or other
property or assets  (including  cash) with  respect to or in  exchange  for such
Common Stock,  then the Company or the successor or  purchasing  Person,  as the
case may be, shall execute with the Holder a written  agreement  providing  that
(x) this Note shall be  convertible  into the kind and amount of shares of stock
and other securities or property or assets (including cash) receivable upon such
reclassification, change, consolidation, merger, combination, sale or conveyance
by the holder of the number of shares of Common Stock  issuable upon  conversion
of this  Note in full  (assuming,  for such  purposes,  a  sufficient  number of
authorized  shares of Common Stock  available to convert this Note)  immediately
prior to such reclassification, change, consolidation, merger, combination, sale
or  conveyance  assuming  such  holder of Common  Stock  did not  exercise  such
holder's  rights of  election,  if any, as to the kind or amount of  securities,
cash or other property  receivable upon such  consolidation,  merger,  statutory
exchange,  sale  or  conveyance  (PROVIDED  that,  if  the  kind  or  amount  of
securities,  cash or other property receivable upon such consolidation,  merger,
statutory exchange,  sale or conveyance is not the same for each share of Common
Stock in respect of which such rights of election  shall not have been exercised
("non-electing  share"),  then for the purposes of this Section 5.4 the kind and
amount of securities, cash or other property receivable upon such consolidation,
merger, statutory exchange, sale or conveyance for each non-electing share shall
be deemed to be the kind and amount so  receivable  per share by a plurality  of
the  non-electing


                                      -31-


shares),  (y) in the case of any such successor or purchasing Person,  upon such
consolidation,  merger,  combination,  sale  or  conveyance  such  successor  or
purchasing Person shall be jointly and severally liable with the Company for the
performance  of all of the  Company's  obligations  under this Note and the Note
Purchase  Agreement and (z) if registration or  qualification  is required under
the 1933 Act or applicable state law for the public resale by the Holder of such
shares of stock and other  securities so issuable upon  conversion of this Note,
such   registration   or   qualification   shall  be  completed  prior  to  such
reclassification,  change,  consolidation,  merger,  combination  or sale.  Such
written  agreement  shall  provide  for  adjustments  which  shall be as  nearly
equivalent  as may  be  practicable  to the  adjustments  provided  for in  this
Article. If, in the case of any such  reclassification,  change,  consolidation,
merger,  combination,  sale or  conveyance,  the stock or other  securities  and
assets  receivable  thereupon  by a holder of shares  of Common  Stock  includes
shares of stock or other  securities and assets of a corporation  other than the
successor   or   purchasing   corporation,   as  the  case   may  be,   in  such
reclassification,   change,   consolidation,   merger,   combination,   sale  or
conveyance,  then such  written  agreement  shall also be executed by such other
corporation  and  shall  contain  such  additional  provisions  to  protect  the
interests  of the Holder as the Board of  Directors  shall  reasonably  consider
necessary by reason of the foregoing,  including, to the extent practicable, the
provisions providing for the repurchase rights set forth in Article IV herein.

                  (b) The above provisions of this Section shall similarly apply
to successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

                  (c) If this  Section 5.4  applies to any event or  occurrence,
Section 5.3 shall not apply.

                  5.5 RESERVATION OF SHARES; SHARES TO BE FULLY PAID; LISTING OF
                      ----------------------------------------------------------
COMMON STOCK.
- ------------
                  (a) The Company  shall reserve and keep  available,  free from
preemptive  rights, out of its authorized but unissued shares of Common Stock or
shares of Common Stock held in treasury,  solely for issuance upon conversion of
this Note, and in addition to the shares of Common Stock required to be reserved
by the terms of the Warrants, sufficient shares to provide for the conversion of
this Note from time to time as this Note is converted.

                  (b) Before  taking any action which would cause an  adjustment
reducing the Conversion Price below the then par value, if any, of the shares of
Common Stock  issuable upon  conversion of this Note,  the Company will take all
corporate action which may, in the opinion of its counsel, be necessary in order
that


                                      -32-


the Company may validly and legally  issue  shares of such Common  Stock at
such adjusted Conversion Price.

                  (c) The  Company  covenants  that all  shares of Common  Stock
issued upon conversion of this Note will be fully paid and non-assessable by the
Company  and free from all taxes,  liens and charges  with  respect to the issue
thereof.

                  (d) The Company  covenants  that if any shares of Common Stock
to be provided  for the purpose of  conversion  of this Note  hereunder  require
registration with or approval of any governmental authority under any federal or
state law before such shares may be validly issued upon conversion,  the Company
will in good faith and as  expeditiously  as  possible  endeavor  to secure such
registration or approval, as the case may be.

                  (e) The Company  covenants that, in the event the Common Stock
shall  be  listed  on the  Nasdaq,  the  NYSE,  the AMEX or any  other  national
securities  exchange,  the Company shall obtain and, so long as the Common Stock
shall be so listed on such market or  exchange,  maintain  approval  for listing
thereon  of all  Common  Stock  issuable  upon  conversion  of or in  payment of
interest on this Note.

                  5.6 NOTICE TO HOLDER PRIOR TO CERTAIN ACTIONS.   In case on or
                      -----------------------------------------
after the Issuance Date:


                  (a) the  Company  shall  declare  a  dividend  (or  any  other
distribution) on its Common Stock (other than in cash out of retained earnings);
or

                  (b) the Company shall authorize the granting to the holders of
its Common Stock of rights or warrants to subscribe for or purchase any share of
any class or any other rights or warrants; or

                  (c)   the   Board   of   Directors    shall    authorize   any
reclassification of the Common Stock of the Company (other than a subdivision or
combination of its  outstanding  Common Stock, or a change in par value, or from
par  value  to no par  value,  or  from  no par  value  to  par  value),  or any
consolidation or merger or other business  combination  transaction to which the
Company is a party and for which approval of any  stockholders of the Company is
required,  or the sale or transfer of all or substantially  all of the assets of
the Company; or

                  (d)  there  shall be  pending  the  voluntary  or  involuntary
dissolution, liquidation or winding-up of the Company;

the Company  shall give the Holder,  as promptly as possible but in any event at
least ten Trading Days prior to the applicable  date  hereinafter  specified,  a
notice  stating (x) the date on which a record is to be taken for the purpose of
such dividend,


                                      -33-


distribution or rights or warrants, or, if a record is not to be taken, the date
as of which the  holders  of  Common  Stock of  record  to be  entitled  to such
dividend,  distribution or rights are to be determined, or (y) the date on which
such  reclassification,   consolidation,   merger,  other  business  combination
transaction, sale, transfer, dissolution,  liquidation or winding-up is expected
to become  effective  or  occur,  and the date as of which it is  expected  that
holders of Common Stock of record who shall be entitled to exchange their Common
Stock for securities or other property  deliverable upon such  reclassification,
consolidation,  merger, other business combination transaction,  sale, transfer,
dissolution,  liquidation or winding-up  shall be determined.  Such notice shall
not include any information which would be material  non-public  information for
purposes of the 1934 Act.  Failure to give such notice,  or any defect  therein,
shall not  affect the  legality  or  validity  of such  dividend,  distribution,
reclassification,    consolidation,   merger,   sale,   transfer,   dissolution,
liquidation or  winding-up.  In the case of any such action of which the Company
gives  such  notice to the  Holder  or is  required  to give such  notice to the
Holder,  the Holder  shall be  entitled  to give a  Conversion  Notice  which is
contingent on the completion of such action.

                  5.7 9.9%  LIMITATION.  (a)  Notwithstanding  anything  to the
                      ----------------
contrary  contained  herein,  the  number of shares of Common  Stock that may be
acquired at any time by the Holder upon  conversion of the Note shall not exceed
a number  that,  when added to the total number of shares of Common Stock deemed
beneficially  owned by such  Holder  (other than by virtue of the  ownership  of
securities or rights to acquire  securities  (including  the Warrants) that have
limitations  on the holder's right to convert,  exercise or purchase  similar to
the  limitation  set forth herein (the  "Excluded  Shares")),  together with all
shares of Common Stock  beneficially owned at such time (other than by virtue of
the  ownership  of Excluded  Shares) by Persons  whose  beneficial  ownership of
Common Stock would be aggregated  with the  beneficial  ownership by such Holder
for  purposes  of  determining  whether  a  group  exists  or  for  purposes  of
determining the Holder's beneficial  ownership (the "Aggregation  Parties"),  in
either such case for  purposes of Section  13(d) of the 1934 Act and  Regulation
13D-G thereunder (including,  without limitation, as the same is made applicable
to  Section  16 of the 1934 Act and the  rules  promulgated  thereunder),  would
result in beneficial ownership by such Holder or such group of more than 9.9% of
the shares of Common  Stock for  purposes of Section  13(d) or Section 16 of the
1934 Act and the rules promulgated  thereunder (as the same may be modified by a
particular Holder as provided herein, the "Restricted Ownership Percentage").  A
Holder  shall  have the right at any time and from  time to time to  reduce  its
Restricted  Ownership  Percentage  immediately upon notice to the Company in the
event  and only to the  extent  that  Section  16 of the  1934 Act or the  rules
promulgated  thereunder (or any successor statute or rules) is changed to reduce
the beneficial  ownership  percentage  threshold thereunder to a percentage less
than  9.9%.  If at any  time  the  limits  in this  Section  5.7  make  the Note
inconvertible  in whole or in part,  the Company shall not by reason  thereof be


                                      -34-


relieved of its  obligation  to issue shares of Common Stock at any time or from
time to time thereafter upon conversion of the Note as and when shares of Common
Stock may be issued in compliance with such restrictions.

                  (b) For  purposes  of this  Section  5.7, in  determining  the
number of outstanding  shares of Common Stock at any time the Holder may rely on
the  number  of  outstanding  shares  of Common  Stock as  reflected  in (1) the
Company's then most recent Form 10-Q,  Form 10-K or other public filing with the
SEC, as the case may be, (2) a public  announcement by the Company that is later
than any such filing  referred to in the  preceding  clause (1) or (3) any other
notice by the Company or its transfer  agent  setting forth the number shares of
Common Stock  outstanding  and knowledge the Holder may have about the number of
shares of Common  Stock  issued upon  conversions  or  exercises of the Notes or
other Common Stock  Equivalents by any Person,  including the Holder,  which are
not  reflected  in the  information  referred  to in the  preceding  clauses (1)
through (3).  Upon the written  request of any Holder,  the Company shall within
three  Business  Days  confirm in writing to such Holder the number of shares of
Common Stock then outstanding.  In any case, the number of outstanding shares of
Common  Stock shall be  determined  after  giving  effect to the  conversion  or
exercise of Common Stock Equivalents,  including the Notes and the Warrants,  by
the Holder or its  affiliates,  in each such case  subsequent to, the date as of
which such number of outstanding shares of Common Stock was reported.

the  daily  Market  Prices  per share of  Common  Stock for the ten  consecutive
Trading Days immediately prior to the date in question;  PROVIDED, HOWEVER, that

issuance or distribution requiring such computation) that requires an adjustment
to the Conversion Price pursuant to Section 5.3(a), (b), (c), (d), (e), (f), (g)
or (h),  occurs during such ten  consecutive  Trading Days, the Market Price for
each  Trading  Day prior to the "ex" date for such other event shall be adjusted
by  multiplying  such Market Price by the same fraction by which the  Conversion
Price is so required to be adjusted as a result of such other event,  (2) if the
"ex" date for any event (other than the issuance or distribution  requiring such
computation)  that requires an adjustment to the  Conversion  Price  pursuant to
Section 5.3(a), (b), (c), (d), (e), (f), (g) or (h), occurs on or after the "ex"
date for the issuance or  distribution  requiring such  computation and prior to
the day in question, the Market Price for each Trading Day on and after the "ex"
date for such other event shall be adjusted by multiplying  such Market Price by
the reciprocal of the fraction by which the  Conversion  Price is so required to
be  adjusted as a result of such other  event,  and (3) if the "ex" date for the
issuance  or  distribution  requiring  such  computation  is prior to the day in
question,  after taking into account any adjustment  required pursuant to clause
(1) or (2) of this  proviso,  the Market  Price for each Trading Day on or after
such "ex" date shall be  adjusted  by adding  thereto the amount of any cash and
the fair  market  value (as  determined  by the Board of  Directors  in a manner
consistent with any  determination  of such value for purposes of Section 5.3(d)
or (f),  whose  determination  shall  be  conclusive  and  described  in a Board
Resolution) of the evidences of indebtedness,  shares of capital stock or assets
being  distributed  applicable  to one share of Common  Stock as of the close of
business on the day before such "ex" date. For purposes of any computation under
Section  5.3(f),  the Current Market Price of the Common Stock on any date shall
be deemed to be the  arithmetic  average of the daily Market Prices per share of
Common Stock for such day and the next two  succeeding  Trading Days;  PROVIDED,
HOWEVER,  that if the "ex"  date for any  event  (other  than the  Tender  Offer
requiring such  computation) that requires an adjustment to the Conversion Price
pursuant to Section  5.3(a),  (b), (c),


                                      -38-


(d), (e), (f), (g) or (h), occurs on or after the Expiration Time for the Tender
Offer requiring such  computation  and prior to the day in question,  the Market
Price for each Trading Day on and after the "ex" date for such other event shall
be adjusted by  multiplying  such Market Price by the reciprocal of the fraction
by which the Conversion  Price is so required to be adjusted as a result of such
other event.  For purposes of this paragraph,  the term "ex" date, (1) when used
with respect to any issuance or distribution,  means the first date on which the
Common Stock  trades,  regular way, on the relevant  exchange or in the relevant
market  from which the Market  Price was  obtained  without the right to receive
such issuance or distribution,  (2) when used with respect to any subdivision or
combination of shares of Common Stock,  means the first date on which the Common
Stock trades,  regular way, on such exchange or in such market after the time at
which such subdivision or combination becomes effective,  and (3) when used with
respect to any  Tender  Offer  means the first  date on which the  Common  Stock
trades,  regular way, on such  exchange or in such market  after the  Expiration
Time of such Tender Offer.  Notwithstanding  the foregoing,  whenever successive
adjustments to the Conversion Price are called for pursuant to Section 5.3, such
adjustments  shall be made to the Current  Market  Price as may be  necessary or
appropriate  to  effectuate  the  intent of Section  5.3 and to avoid  unjust or
inequitable results as determined in good faith by the Board of Directors.
