      This  Convertible  Debenture  (this  "Debenture")  is issued  by  SMARTIRE
SYSTEMS INC, a corporation  organized  and existing  under the laws of the Yukon
Territory  (the  "Obligor"),  to Highgate  House  Funds,  Ltd.  (the  "Holder"),
pursuant to that certain Securities Purchase Agreement (the "Securities Purchase
Agreement") of even date herewith.

      FOR VALUE  RECEIVED,  the Obligor hereby  promises to pay to the Holder or
its   successors   and  assigns  the  principal  sum  of  Two  Million   Dollars
($2,000,000), together with accrued but unpaid interest on the following terms:

      Payments.  Interest on the outstanding  principal  balance hereof shall be
due and payable monthly, in arrears ("Interest Payment"), commencing on July 23,
2005 and shall continue on the first day of each calendar month  thereafter that
any amounts under this Debenture are due and payable (each, an "Interest Payment
Date") as set forth on the Payment Schedule attached hereto. . In lieu of making
an  Interest  Payment  in cash the  Company at its option can elect to make such
Interest Payment in shares of the Company's Common Stock. Principal shall be due
and payable in five (5) equal  installments as set forth in the Payment Schedule
attached hereto  ("Principal  Payment").  The installments of principal shall be
due and payable commencing on June 23, 2006 and subsequent installments shall be
due and payable  every six (6) months  thereafter on the twenty third (23rd) day
of the calendar month ("Principal Payment Date") until the outstanding principal
balance  is paid in full  (the  "Maturity  Date")  as  outlined  in the  Payment
Schedule  attached  hereto or this  Debenture is  converted in full  pursuant to
Section 3. Upon any conversion in part by the Holder in accordance  with Section
3, the Holder and the Obligor shall in good faith  recalculate  the  outstanding
principal  balance  and the  amounts of the  Principal  Payments.  Upon any full
conversion by the Holder in accordance with Section 3 of all of the Interest and
Principal amounts due hereunder all of the Obligor's  payment  obligations shall
terminate. All payments in respect of the indebtedness evidenced hereby shall be
made in either cash of common stock as outlined herein,  and shall be applied in
the following order: to accrued  interest,  principal,  and charges and expenses
owing under or in connection with this Debenture.

                                       1

      In the  event  the  Holder  has  elected  to  convert  a  portion  of this
Debenture,  pursuant to Section 3, the Company, in lieu of receiving a Principal
and Interest  Payment as outlined above,  shall be entitled to an off-set of the
Principal  and  Interest  Payment due  pursuant to the Payment  Schedule and the
dollar amount of the Debenture which has been converted.

      Interest.  Interest  shall  accrue on the  outstanding  principal  balance
hereof at an annual rate equal to ten percent (10%) from the date  principal was
advanced in connection with this Debenture.  Interest shall be calculated on the
basis of a 360-day  year and the actual  number of days  elapsed,  to the extent
permitted by applicable  law.  Interest  hereunder will be paid to the Holder or
its assignee in whose name this  Debenture is  registered  on the records of the
Obligor  regarding  registration  and  transfers of Debentures  (the  "Debenture
Register")as  outlined  herein.  In the event the Holder has  elected to convert
Interest due hereunder into shares of the Company's  Common Stock or the Company
has elected to make an Interest  Payment  hereunder  in shares of the  Company's
Common Stock the amount of stock to be issued will be calculated as follows: the
value of the  stock  shall be the  Closing  Bid  Price on the date the  interest
payment is due or the  conversion  is made.  A number of shares of Common  Stock
with a value equal to the amount of  interest  due shall be issued to the Holder
within five (5) days of the conversion date or on the Interest  Payment Date. No
fractional shares will be issued;  therefore, in the event that the value of the
Common Stock per share does not equal the total  interest due, the Company shall
round up the number of shares due.

Except  for the  capital  stock to be  issued  pursuant  to the  Standby  Equity
Distribution  Agreement  dated  June___,  2005 between the Obligator and Cornell

not, without the prior consent of the Holder, (i) issue or sell any common stock
or  preferred  stock  with or  without  consideration,  (ii)  issue  or sell any
preferred stock, warrant,  option, right,  contract,  call, or other security or

      Section 3. Conversion.

      (a) (i) Conversion at Option of Holder.

            (A) This Debenture shall be convertible  into shares of Common Stock
at the  option of the  Holder,  in whole or in part at any time and from time to
time,  after the  Original  Issue Date (as defined in Section 4) (subject to the
limitations on conversion set forth in Section 3(a)(ii)  hereof).  The number of
shares of Common Stock  issuable upon a conversion  hereunder  equals the sum of
(i) the  quotient  obtained  by  dividing  (x) the  outstanding  amount  of this
Debenture  to be converted  by (y) the  Conversion  Price (as defined in Section
3(c)(i)).  The Obligor shall  deliver  Common Stock  certificates  to the Holder
prior to the Fifth (5th) Trading Day after a Conversion Date.

            (B) Notwithstanding anything to the contrary contained herein, if on
any  Conversion  Date:  (1) the  number of  shares  of Common  Stock at the time
authorized, unissued and unreserved for all purposes, or held as treasury stock,
is  insufficient  to pay  principal  and interest  hereunder in shares of Common
Stock; (2) the Common Stock is not listed or quoted for trading on the OTC or on
a  Subsequent  Market;  (3)  the  Obligor  has  failed  to  timely  satisfy  its
conversion; or (4) the issuance of such shares of Common Stock would result in a
violation of Section 3(a)(ii),  then, at the option of the Holder,  the Obligor,
in lieu of  delivering  shares of Common Stock  pursuant to Section  3(a)(i)(A),
shall deliver, within three (3) Trading Days of each applicable Conversion Date,
an amount in cash equal to the product of the outstanding principal amount to be
converted  plus any interest  due therein  divided by the  Conversion  Price and
multiplied by the highest closing price of the stock from date of the conversion
notice  till the date that such cash  payment is made.  Further,  if the Obligor
shall not have delivered any cash due in respect of conversion of this Debenture
or as  payment of  interest  thereon by the fifth  (5th)  Trading  Day after the
Conversion  Date, the Holder may, by notice to the Obligor,  require the Obligor
to issue shares of Common Stock  pursuant to Section 3(c),  except that for such
purpose  the  Conversion  Price  applicable  thereto  shall be the lesser of the
Conversion  Price on the Conversion Date and the Conversion Price on the date of
such Holder  demand.  Any such shares will be subject to the  provisions of this
Section.

            (C) The Holder shall effect conversions by delivering to the Obligor
a  completed  notice in the form  attached  hereto as  Exhibit A (a  "Conversion
Notice").  The date on which a Conversion Notice is delivered is the "Conversion
Date." Unless the Holder is converting the entire principal  amount  outstanding
under this  Debenture,  the Holder is not required to physically  surrender this
Debenture to the Obligor in order to effect conversions.  Conversions  hereunder
shall have the  effect of  lowering  the  outstanding  principal  amount of this
Debenture plus all accrued and unpaid interest thereon in an amount equal to the
applicable conversion. The Holder and the Obligor shall maintain records showing
the principal amount converted and the date of such conversions. In the event of
any dispute or  discrepancy,  the records of the Holder shall be controlling and
determinative in the absence of manifest error.

                                       5

      (ii) Certain Conversion Restrictions.

            (A) A Holder may not convert  this  Debenture  or receive  shares of
Common Stock as payment of interest  hereunder to the extent such  conversion or
receipt of such interest  payment would result in the Holder,  together with any
affiliate thereof, beneficially owning (as determined in accordance with Section
13(d) of the Exchange  Act and the rules  promulgated  thereunder)  in excess of
4.9% of the then issued and outstanding shares of Common Stock, including shares
of Common Stock  issuable upon  conversion  of, and payment of interest on, this
Debenture  or upon  exercise  of, or  conversion  of, any other  security of the
Obligor, held by such Holder after application of this Section. Since the Holder
will not be  obligated  to report to the  Obligor the number of shares of Common
Stock it may hold at the time of a conversion  hereunder,  unless the conversion
at issue would  result in the  issuance  of shares of Common  Stock in excess of
4.9% of the then outstanding  shares of Common Stock without regard to any other
shares which may be  beneficially  owned by the Holder or an affiliate  thereof,
the Holder shall have the  authority  and  obligation  to determine  whether the
restriction  contained  in this  Section  will limit any  particular  conversion
hereunder  and to the extent  that the  Holder  determines  that the  limitation
contained in this Section  applies,  the  determination  of which portion of the
principal  amount of this Debenture is convertible  shall be the  responsibility
and  obligation of the Holder.  If the Holder has delivered a Conversion  Notice
for a  principal  amount of this  Debenture  that,  without  regard to any other
shares that the Holder or its affiliates may  beneficially  own, would result in
the issuance in excess of the  permitted  amount  hereunder,  the Obligor  shall
notify the Holder of this fact and shall  honor the  conversion  for the maximum
principal amount permitted to be converted on such Conversion Date in accordance
with the  periods  described  in Section  3(a)(i)(A)  and,  at the option of the
Holder,  either retain any principal amount tendered for conversion in excess of
the  permitted  amount  hereunder for future  conversions  or return such excess
principal amount to the Holder.  The provisions of this Section may be waived by
a Holder (but only as to itself and not to any other  Holder) upon not less than
65 days prior notice to the Obligor.  Other  Holders  shall be unaffected by any
such waiver.

      (b) (i)  Nothing  herein  shall  limit a Holder's  right to pursue  actual
damages  or declare  an Event of  Default  pursuant  to Section 2 herein for the
Obligor 's failure to deliver  certificates  representing shares of Common Stock
upon conversion  within the period  specified  herein and such Holder shall have
the right to pursue all remedies  available to it at law or in equity including,
without limitation,  a decree of specific  performance and/or injunctive relief,
in each case  without  the need to post a bond or provide  other  security.  The
exercise  of any such  rights  shall not  prohibit  the Holder  from  seeking to
enforce damages pursuant to any other Section hereof or under applicable law.

            (ii) In addition to any other rights available to the Holder, if the
Obligor fails to deliver to the Holder such certificate or certificates pursuant
to Section 3(a)(i)(A) by the fifth Trading Day after the Conversion Date, and if
after such fifth  (5th)  Trading  Day the Holder  purchases  (in an open  market
transaction or otherwise)  Common Stock to deliver in  satisfaction of a sale by
such Holder of the Underlying Shares which the Holder anticipated receiving upon
such  conversion  (a  "Buy-In"),  then the Obligor  shall (A) pay in cash to the
Holder (in addition to any  remedies  available to or elected by the Holder) the
amount by which (x) the  Holder's  total  purchase  price  (including  brokerage
commissions,  if any) for the Common Stock so purchased  exceeds (y) the product
of (1) the  aggregate  number of shares of Common  Stock that such Holder  would
have received from the conversion at issue multiplied by (2) the market price of
the Common Stock at the time of the sale giving rise to such purchase obligation
and (B) at the option of the Holder, either reissue a Debenture in the principal
amount equal to the principal  amount of the attempted  conversion or deliver to
the Holder the number of shares of Common  Stock that would have been issued had
the  Obligor  timely  complied  with its  delivery  requirements  under  Section
3(a)(i)(A).  For example,  if the Holder  purchases  Common Stock having a total
purchase  price of Eleven  Thousand  Dollars  ($11,000)  to cover a Buy-In  with
respect to an  attempted  conversion  of  Debentures  with  respect to which the
market price of the  Underlying  Shares on the date of conversion was a total of
Ten Thousand  Dollars  ($10,000) under clause (A) of the  immediately  preceding
sentence,  the Obligor shall be required to pay the Holder One Thousand  Dollars
($1,000).  The Holder shall provide the Obligor  written  notice  indicating the
amounts payable to the Holder in respect of the Buy-In.

                                       6

      (c) (i) The  conversion  price (the  "Conversion  Price") in effect on any
Conversion Date shall be equal to $0.1125, which may be adjusted pursuant to the
other terms of this Debenture.

            (ii)  If  the  Obligor,   at  any  time  while  this   Debenture  is
outstanding,  shall (a) pay a stock dividend or otherwise make a distribution or
distributions  on  shares  of its  Common  Stock or any  other  equity or equity
equivalent   securities  payable  in  shares  of  Common  Stock,  (b)  subdivide
outstanding  shares of Common Stock into a larger number of shares,  (c) combine
(including  by way of reverse  stock split)  outstanding  shares of Common Stock
into a smaller number of shares, or (d) issue by  reclassification  of shares of
the Common Stock any shares of capital stock of the Obligor, then the Conversion
Price  shall be  multiplied  by a fraction of which the  numerator  shall be the
number of shares of Common Stock (excluding treasury shares, if any) outstanding
before such event and of which the denominator  shall be the number of shares of
Common Stock  outstanding after such event. Any adjustment made pursuant to this
Section  shall  become  effective  immediately  after  the  record  date for the
determination of stockholders  entitled to receive such dividend or distribution
and shall become effective immediately after the effective date in the case of a
subdivision, combination or re-classification.

            (iii) Except for shares of capital stock or  securities  convertible
into or exercisable  for shares of capital stock issued pursuant to a commitment
dated prior to the date hereof, if the Obligor, at any time while this Debenture
is outstanding, shall issue rights, options or warrants to all holders of Common
Stock (and not to the Holder) entitling them to subscribe for or purchase shares
of  Common  Stock at a price per share  less than the  Closing  Bid Price at the
record date mentioned below,  then the Conversion Price shall be multiplied by a
fraction,  of which the denominator  shall be the number of shares of the Common
Stock (excluding treasury shares, if any) outstanding on the date of issuance of
such rights or warrants  (plus the number of  additional  shares of Common Stock
offered for  subscription or purchase),  and of which the numerator shall be the
number  of  shares of the  Common  Stock  (excluding  treasury  shares,  if any)
outstanding on the date of issuance of such rights or warrants,  plus the number
of shares which the  aggregate  offering  price of the total number of shares so
offered would purchase at such Closing Bid Price.  Such adjustment shall be made
whenever  such  rights  or  warrants  are  issued,  and shall  become  effective
immediately after the record date for the determination of stockholders entitled
to receive such rights, options or warrants. However, upon the expiration of any
such  right,  option or  warrant  to  purchase  shares of the  Common  Stock the
issuance of which resulted in an adjustment in the Conversion  Price pursuant to
this  Section,  if any such right,  option or warrant shall expire and shall not
have been exercised, the Conversion Price shall immediately upon such expiration
be recomputed and effective immediately upon such expiration be increased to the
price  which it would have been (but  reflecting  any other  adjustments  in the
Conversion  Price made  pursuant to the  provisions  of this  Section  after the
issuance of such rights or warrants) had the adjustment of the Conversion  Price
made upon the  issuance of such  rights,  options or  warrants  been made on the
basis of offering for subscription or purchase only that number of shares of the
Common Stock  actually  purchased  upon the exercise of such rights,  options or
warrants actually exercised.

                                       7
<PAGE>

            (iv) Except for shares of capital  stock or  securities  convertible
into or exercisable  for shares of capital stock issued pursuant to a commitment
dated prior to the date hereof,  if the Obligor or any  subsidiary  thereof,  as
applicable,  with respect to Common Stock Equivalents (as defined below), at any
time while this Debenture is outstanding,  shall issue shares of Common Stock or
rights, warrants,  options or other securities or debt that are convertible into
or  exchangeable  for  shares  of  Common  Stock  ("Common  Stock  Equivalents")
entitling  any Person to acquire  shares of Common  Stock,  at a price per share
less than the  Conversion  Price (if the  holder of the  Common  Stock or Common
Stock  Equivalent so issued shall at any time,  whether by operation of purchase
price adjustments, reset provisions,  floating conversion,  exercise or exchange
prices or  otherwise,  or due to warrants,  options or rights per share which is
issued in connection with such issuance, be entitled to receive shares of Common
Stock at a price  per  share  which  is less  than the  Conversion  Price,  such
issuance shall be deemed to have occurred for less than the  Conversion  Price),
then, at the sole option of the Holder,  the Conversion  Price shall be adjusted
to mirror the  conversion,  exchange or purchase  price for such Common Stock or
Common Stock Equivalents (including any reset provisions thereof) at issue. Such
adjustment shall be made whenever such Common Stock or Common Stock  Equivalents
are issued.  The Obligor shall notify the Holder in writing,  no later than five
(5)  business  days  following  the issuance of any Common Stock or Common Stock
Equivalent subject to this Section,  indicating therein the applicable  issuance
price, or of applicable reset price, exchange price,  conversion price and other
pricing  terms.  No  adjustment  under this Section shall be made as a result of
issuances and exercises of options to purchase shares of Common Stock issued for
compensatory  purposes  pursuant to any of the  Obligor's  stock option or stock
purchase plans.

            (v) If the Obligor, at any time while this Debenture is outstanding,
shall  distribute  to all  holders  of  Common  Stock  (and  not to the  Holder)
evidences of its  indebtedness  or assets or rights or warrants to subscribe for
or purchase any security,  then in each such case the Conversion  Price at which
this  Debenture  shall   thereafter  be  convertible   shall  be  determined  by
multiplying the Conversion Price in effect  immediately prior to the record date
fixed for determination of stockholders entitled to receive such distribution by
a fraction of which the denominator shall be the Closing Bid Price determined as
of the record date  mentioned  above,  and of which the numerator  shall be such
Closing Bid Price on such  record  date less the then fair market  value at such
record  date of the  portion  of such  assets or  evidence  of  indebtedness  so
distributed  applicable  to  one  outstanding  share  of  the  Common  Stock  as
determined  by the  Board  of  Directors  in good  faith.  In  either  case  the
adjustments  shall be  described  in a  statement  provided to the Holder of the
portion  of  assets  or  evidences  of   indebtedness  so  distributed  or  such
subscription  rights  applicable to one share of Common Stock.  Such  adjustment
shall be made whenever any such  distribution is made and shall become effective
immediately after the record date mentioned above.

            (vi) In case of any  reclassification  of the  Common  Stock  or any
compulsory  share exchange  pursuant to which the Common Stock is converted into
other securities,  cash or property,  the Holder shall have the right thereafter
to, at its option, (A) convert the then outstanding  principal amount,  together
with all accrued but unpaid  interest and any other amounts then owing hereunder
in respect of this Debenture into the shares of stock and other securities, cash
and property receivable upon or deemed to be held by holders of the Common Stock
following  such  reclassification  or share  exchange,  and the  Holder  of this
Debenture  shall  be  entitled  upon  such  event  to  receive  such  amount  of
securities,  cash or property  as the shares of the Common  Stock of the Obligor
into which the then outstanding principal amount,  together with all accrued but
unpaid  interest and any other  amounts then owing  hereunder in respect of this
Debenture could have been converted  immediately prior to such  reclassification
or share exchange would have been entitled, or (B) require the Obligor to prepay
the outstanding principal amount of this Debenture,  plus all interest and other
amounts due and payable  thereon.  The entire  prepayment price shall be paid in
cash. This provision shall  similarly apply to successive  reclassifications  or
share exchanges.

            (vii) All  calculations  under this Section 3 shall be rounded up to
the nearest $0.001 of a share.

            (viii)  Whenever the  Conversion  is adjusted  pursuant to Section 3
hereof, the Obligor shall promptly mail to the Holder a notice setting forth the
Conversion  Price after such  adjustment and setting forth a brief  statement of
the facts requiring such adjustment.

            (ix) If (A) the  Obligor  shall  declare  a  dividend  (or any other
distribution)  on the Common  Stock;  (B) the  Obligor  shall  declare a special
nonrecurring  cash  dividend on or a  redemption  of the Common  Stock;  (C) the
Obligor  shall  authorize the granting to all holders of the Common Stock rights
or warrants to  subscribe  for or  purchase  any shares of capital  stock of any
class or of any  rights;  (D) the  approval of any  stockholders  of the Obligor
shall be required in connection with any  reclassification  of the Common Stock,
any  consolidation  or  merger  to which  the  Obligor  is a party,  any sale or
transfer  of all or  substantially  all of the  assets  of the  Obligor,  of any
compulsory  share  exchange  whereby the Common  Stock is  converted  into other
securities,  cash or property;  or (E) the Obligor shall authorize the voluntary
or  involuntary  dissolution,  liquidation  or winding up of the  affairs of the
Obligor;  then, in each case, the Obligor shall cause to be filed at each office
or agency maintained for the purpose of conversion of this Debenture,  and shall
cause to be mailed to the Holder at its last address as it shall appear upon the
stock  books of the  Obligor,  at  least  ten (10)  calendar  days  prior to the
applicable record or effective date hereinafter  specified, a notice stating (x)
the date on which a record  is to be taken  for the  purpose  of such  dividend,
distribution, redemption, rights or warrants, or if a record is not to be taken,
the date as of which the holders of the Common Stock of record to be entitled to
such  dividend,  distributions,   redemption,  rights  or  warrants  are  to  be
determined  or (y)  the  date on  which  such  reclassification,  consolidation,
merger,  sale,  transfer or share  exchange is expected to become  effective  or
close,  and the date as of which it is expected that holders of the Common Stock
of record  shall be entitled to exchange  their  shares of the Common  Stock for
securities,  cash or other  property  deliverable  upon  such  reclassification,
consolidation,  merger,  sale,  transfer or share exchange,  provided,  that the
failure to mail such  notice or any defect  therein  or in the  mailing  thereof
shall not affect the validity of the corporate  action  required to be specified
in such  notice.  The Holder is entitled to convert  this  Debenture  during the
10-day calendar period  commencing the date of such notice to the effective date
of the event triggering such notice.

                                       9
<PAGE>

            (x) In case of any (1) merger or consolidation of the Obligor or any
subsidiary  of the  Obligor  with or into  another  Person,  or (2)  sale by the
Obligor or any  subsidiary of the Obligor of more than one-half of the assets of
the Obligor in one or a series of related transactions,  a Holder shall have the
right to (A) exercise any rights under Section  2(b),  (B) convert the aggregate
amount of this  Debenture  then  outstanding  into the shares of stock and other
securities, cash and property receivable upon or deemed to be held by holders of
Common Stock following such merger, consolidation or sale, and such Holder shall
be entitled  upon such event or series of related  events to receive such amount
of  securities,  cash and property as the shares of Common Stock into which such
aggregate   principal  amount  of  this  Debenture  could  have  been  converted
immediately  prior to such  merger,  consolidation  or  sales  would  have  been
entitled, or (C) in the case of a merger or consolidation, require the surviving
entity to issue to the Holder a convertible  Debenture  with a principal  amount
equal to the  aggregate  principal  amount of this  Debenture  then held by such
Holder,  plus all accrued and unpaid  interest and other amounts owing  thereon,
which such  newly  issued  convertible  Debenture  shall  have  terms  identical
(including with respect to conversion) to the terms of this Debenture, and shall
be entitled to all of the rights and  privileges of the Holder of this Debenture
set forth  herein and the  agreements  pursuant  to which this  Debentures  were
issued. In the case of clause (C), the conversion price applicable for the newly
issued shares of convertible preferred stock or convertible  Debentures shall be
based upon the amount of securities, cash and property that each share of Common
Stock  would  receive in such  transaction  and the  Conversion  Price in effect
immediately prior to the effectiveness or closing date for such transaction. The
terms of any such merger,  sale or consolidation  shall include such terms so as
to  continue to give the Holder the right to receive  the  securities,  cash and
property set forth in this Section upon any  conversion or redemption  following
such event. This provision shall similarly apply to successive such events.

      (d) The  Obligor  covenants  that it will at all  times  reserve  and keep
available out of its authorized  and unissued  shares of Common Stock solely for
the  purpose of  issuance  upon  conversion  of this  Debenture  and  payment of
interest on this Debenture, each as herein provided, free from preemptive rights
or any other actual contingent purchase rights of persons other than the Holder,
not less than such number of shares of the Common Stock as shall (subject to any
additional  requirements  of the  Obligor as to  reservation  of such shares set
forth in this  Debenture) be issuable  (taking into account the  adjustments and
restrictions  of Sections 2(b) and 3(c)) upon the conversion of the  outstanding
principal  amount of this  Debenture  and  payment of  interest  hereunder.  The
Obligor  covenants  that all shares of Common  Stock  that shall be so  issuable
shall,  upon  issue,  be duly and  validly  authorized,  issued and fully  paid,
nonassessable  and, if the  Underlying  Shares  Registration  Statement has been
declared  effective  under the  Securities  Act,  registered  for public sale in
accordance with such Underlying Shares Registration Statement.

                                       10

      (e) Upon a conversion hereunder the Obligor shall not be required to issue
stock certificates representing fractions of shares of the Common Stock, but may
if otherwise permitted,  make a cash payment in respect of any final fraction of
a share based on the Closing Bid Price at such time. If the Obligor  elects not,
or is unable,  to make such a cash  payment,  the Holder  shall be  entitled  to
receive,  in lieu of the final  fraction  of a share,  one whole share of Common
Stock.

      (f) The  issuance  of  certificates  for  shares  of the  Common  Stock on
conversion of this Debenture  shall be made without charge to the Holder thereof
for any documentary stamp or similar taxes that may be payable in respect of the
issue or delivery of such  certificate,  provided  that the Obligor shall not be
required to pay any tax that may be payable in respect of any transfer  involved
in the issuance and delivery of any such  certificate  upon conversion in a name
other than that of the Holder of such  Debenture  so  converted  and the Obligor
shall not be required to issue or deliver such certificates  unless or until the
person or persons requesting the issuance thereof shall have paid to the Obligor
the  amount of such tax or shall have  established  to the  satisfaction  of the
Obligor  that  such  tax  has  been  paid.  The  Holder  shall  pay  any and all
withholding  taxes assessed in connection with the transactions  contemplated by
this Debenture.

      (g) Any notices,  consents,  waivers or other  communications  required or
permitted  to be given  under the terms  hereof  must be in writing  and will be
deemed to have been delivered: (i) upon receipt, when delivered personally; (ii)
upon receipt,  when sent by facsimile (provided  confirmation of transmission is
mechanically or electronically generated and kept on file by the sending party);
or  (iii)  one (1)  trading  day  after  deposit  with a  nationally  recognized
overnight  delivery  service,  in each case  properly  addressed to the party to
receive the same.  The addresses and facsimile  numbers for such  communications

Debenture. The failure of the Holder to insist upon strict adherence to any term
of this Debenture on one or more  occasions  shall not be considered a waiver or

not at any time insist upon,  plead, or in any manner  whatsoever  claim or take
the benefit or advantage of, any stay, extension or usury law or other law which
would  prohibit  or forgive  the  Obligor  from paying all or any portion of the
principal of or interest on this  Debenture  as  contemplated  herein,  wherever
enacted,  now or at any time  hereafter  in  force,  or  which  may  affect  the
covenants or the performance of this  indenture,  and the Obligor (to the extent
it may lawfully do so) hereby  expressly waives all benefits or advantage of any
such law,  and  covenants  that it will not, by resort to any such law,  hinder,
delay or impeded the  execution of any power herein  granted to the Holder,  but
will  suffer and permit  the  execution  of every such as though no such law has
been enacted.

due on a day other than a Business  Day,  such payment shall be made on the next
succeeding Business Day.

      Section 14. THE PARTIES HEREBY  KNOWINGLY,  VOLUNTARILY AND  INTENTIONALLY
WAIVE  THE  RIGHT  ANY OF THEM  MAY HAVE TO A TRIAL  BY JURY IN  RESPECT  OF ANY
LITIGATION  BASED  HEREON OR ARISING OUT OF,  UNDER OR IN  CONNECTION  WITH THIS

                        Warrant to Purchase Common Stock

Warrant No.: 001                                    Number of Shares: 41,668,750

Date of Issuance: June 23, 2005

Smartire  Systems Inc., a corporation  organized and existing  under the laws of
the Yukon  Territory  (the  "Company"),  hereby  certifies  that, for Ten United
States Dollars ($10.00) and other good and valuable  consideration,  the receipt
and sufficiency of which are hereby acknowledged,  Cornell Capital Partners, LP,
a Delaware limited partnership ("Cornell"),  the registered holder hereof or its
permitted  assigns,  is  entitled,  subject  to the terms set  forth  below,  to
purchase from the Company upon  surrender of this Warrant,  at any time or times
on or after  the date  hereof,  but not after  11:59  P.M.  Eastern  Time on the
Expiration  Date (as defined  herein)  forty one million six hundred sixty eight
thousand seven hundred fifty (41,668,750) fully paid and nonassessable shares of
Common Stock (as defined  herein) of the Company (the  "Warrant  Shares") at the
exercise  price per share  provided  in Section  1(b)  below or as  subsequently
adjusted;  provided,  however,  that in no event shall the holder be entitled to
exercise this Warrant for a number of Warrant Shares in excess of that number of
Warrant  Shares  which,  upon giving  effect to such  exercise,  would cause the
aggregate number of shares of Common Stock  beneficially owned by the holder and
its  affiliates  to exceed 4.99% of the  outstanding  shares of the Common Stock
following such exercise,  except within sixty (60) days of the Expiration  Date.
For purposes of the foregoing proviso,  the aggregate number of shares of Common
Stock  beneficially  owned by the holder and its  affiliates  shall  include the
number of shares of Common  Stock  issuable  upon  exercise of this Warrant with
respect to which the  determination  of such  proviso is being  made,  but shall
exclude  shares of Common Stock which would be issuable upon (i) exercise of the
remaining,  unexercised  Warrants  beneficially  owned  by the  holder  and  its
affiliates  and (ii) exercise or conversion of the  unexercised  or  unconverted
portion of any other securities of the Company  beneficially owned by the holder
and its affiliates  (including,  without  limitation,  any convertible  notes or
preferred stock) subject to a limitation on conversion or exercise  analogous to
the limitation contained herein.  Except as set forth in the preceding sentence,
for purposes of this  paragraph,  beneficial  ownership  shall be  calculated in
accordance  with  Section  13(d) of the  Securities  Exchange  Act of  1934,  as
amended.  For purposes of this Warrant, in determining the number of outstanding
shares of Common Stock a holder may rely on the number of outstanding  shares of
Common Stock as reflected in (1) the  Company's  most recent Form 10-QSB or Form
10-KSB, as the case may be, (2) a more recent public announcement by the Company
or (3) any other notice by the Company or its transfer  agent  setting forth the
number of shares of Common Stock  outstanding.  Upon the written  request of any
holder, the Company shall promptly,  but in no event later than one (1) Business
Day following the receipt of such notice,  confirm in writing to any 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  exercise of Warrants (as defined  below) by such holder and its  affiliates
since the date as of which such number of outstanding shares of Common Stock was
reported.

      Section  2.  Exercise  of  Warrant.  Subject  to the terms and  conditions

Business  Day on or  after  the  opening  of  business  on  such  Business  Day,
commencing  with the first day after the date  hereof,  and prior to 11:59  P.M.
Eastern Time on the Expiration Date, by (i) delivery of a written notice, in the
form of the  subscription  notice  attached as Exhibit A hereto  (the  "Exercise
Notice"), of such holder's election to exercise this Warrant, which notice shall
specify  the  number of  Warrant  Shares to be  purchased,  (ii)  payment to the

exercised (plus any applicable issue or transfer taxes) (the "Aggregate Exercise
Price") in cash or wire transfer of  immediately  available  funds and (iii) the
surrender of this  Warrant (or an  indemnification  undertaking  with respect to
this Warrant in the case of its loss,  theft or destruction) to a common carrier
for  overnight  delivery to the Company as soon as  practicable  following  such
date. In the event of any exercise of the rights  represented by this Warrant in
compliance with this Section 2(a), the Company shall on the fifth (5th) Business
Day following the date of receipt of the Exercise Notice, the Aggregate Exercise
Price and this Warrant (or an  indemnification  undertaking with respect to this
Warrant in the case of its loss,  theft or  destruction)  and the receipt of the
representations of the holder specified in Section 6 hereof, if requested by the
Company  (the  "Exercise  Delivery  Documents"),  and if the Common Stock is DTC
eligible  credit such  aggregate  number of shares of Common  Stock to which the
holder shall be entitled to the holder's or its designee's  balance account with
The Depository Trust Company; provided, however, if the holder who submitted the
Exercise Notice requested physical delivery of any or all of the Warrant Shares,
or, if the Common Stock is not DTC eligible then the Company shall, on or before
the  fifth  (5th)  Business  Day  following  receipt  of the  Exercise  Delivery
Documents, issue and surrender to a common carrier for overnight delivery to the
address specified in the Exercise Notice, a certificate,  registered in the name
of the  holder,  for the  number of shares of Common  Stock to which the  holder
shall be entitled pursuant to such request. Upon delivery of the Exercise Notice
and Aggregate Exercise Price referred to in clause (ii) above the holder of this
Warrant shall be deemed for all corporate  purposes to have become the holder of
record of the  Warrant  Shares  with  respect  to which  this  Warrant  has been
exercised.  In the case of a  dispute  as to the  determination  of the  Warrant
Exercise  Price,  the Closing  Bid Price or the  arithmetic  calculation  of the
Warrant  Shares,  the Company shall  promptly  issue to the holder the number of
Warrant Shares that is not disputed and shall submit the disputed determinations
or arithmetic  calculations to the holder via facsimile  within one (1) Business
Day of receipt of the holder's  Exercise  Notice.  If the holder and the Company
are unable to agree upon the  determination  of the  Warrant  Exercise  Price or
arithmetic calculation of the Warrant Shares within one (1) day of such disputed
determination or arithmetic  calculation being submitted to the holder, then the
Company shall immediately submit via facsimile (i) the disputed determination of
the Warrant Exercise Price or the Closing Bid Price to an independent, reputable
investment  banking  firm or (ii) the  disputed  arithmetic  calculation  of the
Warrant Shares to its independent,  outside accountant.  The Company shall cause
the investment  banking firm or the  accountant,  as the case may be, to perform
the  determinations or calculations and notify the Company and the holder of the
results no later than  forty-eight  (48)  hours  from the time it  receives  the
disputed  determinations  or  calculations.  Such  investment  banking firm's or
accountant's  determination or calculation,  as the case may be, shall be deemed
conclusive absent manifest error.

            (a) Unless the rights represented by this Warrant shall have expired
or shall have been fully  exercised,  the Company shall,  as soon as practicable
and in no event later than five (5) Business  Days after any exercise and at its
own  expense,  issue a new Warrant  identical  in all  respects to this  Warrant
exercised  except it shall  represent  rights to purchase  the number of Warrant
Shares  purchasable  immediately  prior  to such  exercise  under  this  Warrant
exercised,  less the number of Warrant Shares with respect to which such Warrant
is exercised.

            (b) No fractional  Warrant Shares are to be issued upon any pro rata
exercise of this  Warrant,  but rather the number of Warrant  Shares issued upon
such  exercise of this Warrant  shall be rounded up or down to the nearest whole
number.

            (c) If the Company or its  Transfer  Agent shall fail for any reason
or for no reason to issue to the  holder  within ten (10) days of receipt of the
Exercise Delivery  Documents,  a certificate for the number of Warrant Shares to
which the holder is entitled or to credit the holder's  balance account with The
Depository  Trust Company for such number of Warrant  Shares to which the holder
is entitled upon the holder's  exercise of this Warrant,  the Company shall,  in
addition  to any other  remedies  under  this  Warrant  or the  Placement  Agent
Agreement or otherwise  available to such holder,  pay as additional  damages in
cash to such  holder on each day the  issuance of such  certificate  for Warrant
Shares is not timely  effected  an amount  equal to 0.025% of the product of (A)
the sum of the  number of  Warrant  Shares  not issued to the holder on a timely
basis and to which the holder is entitled,  and (B) the Closing Bid Price of the
Common Stock for the trading day  immediately  preceding  the last possible date
which the Company  could have issued  such  Common  Stock to the holder  without
violating this Section 2.

            (d) If within  ten (10)  days  after the  Company's  receipt  of the
Exercise Delivery  Documents,  the Company fails to deliver a new Warrant to the
holder  for the  number of  Warrant  Shares  to which  such  holder is  entitled
pursuant to Section 2 hereof,  then, in addition to any other available remedies
under this Warrant or the Placement Agent Agreement,  or otherwise  available to
such holder,  the Company shall pay as additional damages in cash to such holder
on each day after such tenth  (10th) day that such  delivery of such new Warrant
is not timely  effected  in an amount  equal to 0.25% of the  product of (A) the
number of Warrant Shares represented by the portion of this Warrant which is not
being  exercised  and (B) the  Closing  Bid  Price of the  Common  Stock for the
trading day immediately preceding the last possible date which the Company could
have issued such Warrant to the holder without violating this Section 2.

      Section 3. Covenants as to Common Stock.  The Company hereby covenants and
agrees as follows:

            (a) This Warrant is, and any Warrants issued in substitution  for or
replacement  of this Warrant will upon issuance be, duly  authorized and validly
issued.

            (b) All Warrant  Shares which may be issued upon the exercise of the
rights represented by this Warrant will, upon issuance, be validly issued, fully
paid and nonassessable  and free from all taxes,  liens and charges with respect
to the issue thereof.

            (c) During the period  within which the rights  represented  by this
Warrant may be  exercised,  the Company  will at all times have  authorized  and
reserved at least one hundred  percent  (100%) of the number of shares of Common
Stock needed to provide for the exercise of the rights then  represented by this
Warrant and the par value of said shares will at all times be less than or equal
to the applicable  Warrant  Exercise  Price. If at any time the Company does not
have a sufficient  number of shares of Common Stock  authorized  and  available,
then the  Company  shall  call and hold a special  meeting  of its  stockholders
within  thirty  (30) days of that time for the sole  purpose of  increasing  the
number of authorized shares of Common Stock.

            (d) If at any time after the date  hereof the  Company  shall file a
registration statement, the Company shall include the Warrant Shares issuable to
the holder, pursuant to the terms of this Warrant and shall maintain, so long as
any other shares of Common Stock shall be so listed, such listing of all Warrant
Shares from time to time  issuable  upon the exercise of this  Warrant;  and the
Company  shall  so  list on  each  national  securities  exchange  or  automated
quotation  system,  as the case may be, and shall  maintain such listing of, any
other shares of capital stock of the Company  issuable upon the exercise of this
Warrant if and so long as any  shares of the same class  shall be listed on such
national securities exchange or automated quotation system.

            (e)  The  Company   will  not,  by  amendment  of  its  Articles  of
Incorporation or through any 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  by it  hereunder,  but will at all times in good  faith
assist in the  carrying  out of all the  provisions  of this  Warrant and in the
taking of all such action as may  reasonably  be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
against dilution or other  impairment,  consistent with the tenor and purpose of
this  Warrant.  The  Company  will not  increase  the par value of any shares of
Common Stock  receivable  upon the  exercise of this  Warrant  above the Warrant
Exercise  Price  then in effect,  and (ii) will take all such  actions as may be
necessary or appropriate in order that the Company may validly and legally issue
fully paid and  nonassessable  shares of Common  Stock upon the exercise of this
Warrant.

            (f) This Warrant will be binding upon any entity  succeeding  to the
Company by merger,  consolidation or acquisition of all or substantially  all of
the Company's assets.

      Section 4.  Taxes.  The  Company  shall pay any and all taxes,  except any
applicable  withholding,  which may be payable  with respect to the issuance and
delivery of Warrant Shares upon exercise of this Warrant.

      Section 5. Warrant  Holder Not Deemed a  Stockholder.  Except as otherwise
specifically  provided  herein,  no holder,  as such,  of this Warrant  shall be
entitled  to vote or  receive  dividends  or be deemed  the  holder of shares of
capital stock of the Company for any purpose,  nor shall  anything  contained in
this Warrant be construed to confer upon the holder hereof,  as such, any of the
rights of a  stockholder  of the Company or any right to vote,  give or withhold
consent to any corporate  action  (whether any  reorganization,  issue of stock,
reclassification  of stock,  consolidation,  merger,  conveyance or  otherwise),
receive  notice of  meetings,  receive  dividends  or  subscription  rights,  or
otherwise,  prior to the  issuance to the holder of this  Warrant of the Warrant
Shares which he or she is then entitled to receive upon the due exercise of this
Warrant.  In addition,  nothing  contained in this Warrant shall be construed as
imposing  any  liabilities  on such  holder to  purchase  any  securities  (upon
exercise of this  Warrant or  otherwise)  or as a  stockholder  of the  Company,
whether  such  liabilities  are  asserted by the Company or by  creditors of the
Company.  Notwithstanding this Section 5, the Company will provide the holder of
this Warrant with copies of the same notices and other  information given to the
stockholders of the Company generally, contemporaneously with the giving thereof
to the stockholders.

      Section 6.  Representations of Holder. The holder of this Warrant,  by the
acceptance hereof,  represents that it is acquiring this Warrant and the Warrant
Shares for its own account for investment  only and not with a view towards,  or
for resale in connection  with, the public sale or  distribution of this Warrant
or the Warrant Shares, except pursuant to sales registered or exempted under the
Securities Act; provided,  however,  that by making the representations  herein,
the holder does not agree to hold this Warrant or any of the Warrant  Shares for
any minimum or other  specific  term and  reserves  the right to dispose of this
Warrant and the Warrant  Shares at any time in accordance  with or pursuant to a
registration  statement or an exemption  under the Securities Act. The holder of
this Warrant further  represents,  by acceptance hereof,  that, as of this date,
such  holder  is an  "accredited  investor"  as  such  term is  defined  in Rule
501(a)(1) of Regulation D promulgated by the Securities and Exchange  Commission
under the  Securities  Act (an  "Accredited  Investor").  Upon  exercise of this
Warrant the holder shall, if requested by the Company,  confirm in writing, in a
form satisfactory to the Company, that the Warrant Shares so purchased are being
acquired  solely for the holder's own account and not as a nominee for any other
party,  for  investment,  and not with a view toward  distribution or resale and
that such holder is an  Accredited  Investor.  If such  holder  cannot make such
representations  because  they  would  be  factually  incorrect,  it  shall be a
condition to such  holder's  exercise of this  Warrant that the Company  receive
such other  representations  as the Company  considers  reasonably  necessary to
assure the Company that the  issuance of its  securities  upon  exercise of this
Warrant shall not violate any United States or state securities laws.

      Section 7. Ownership and Transfer.

            (a) The Company shall  maintain at its principal  executive  offices
(or such other office or agency of the Company as it may  designate by notice to
the holder  hereof),  a register for this  Warrant,  in which the Company  shall
record the name and  address of the person in whose name this  Warrant  has been
issued,  as well as the name and  address of each  transferee.  The  Company may
treat the person in whose name any Warrant is  registered on the register as the
owner and holder  thereof for all  purposes,  notwithstanding  any notice to the
contrary,  but in all events  recognizing  any transfers made in accordance with
the terms of this Warrant.

      Section 8. Adjustment of Warrant Exercise Price and Number of Shares.  The
Warrant  Exercise  Price and the number of shares of Common Stock  issuable upon
exercise of this Warrant shall be adjusted from time to time as follows:

            (a)  Adjustment of Warrant  Exercise Price and Number of Shares upon
Issuance  of Common  Stock.  If and  whenever  after the  Issuance  Date of this
Warrant,  the Company issues or sells,  or is deemed to have issued or sold, any
shares of Common Stock (other than (i)  Excluded  Securities  and (ii) shares of
Common  Stock  which are issued or deemed to have been  issued by the Company in
connection  with an Approved  Stock Plan or upon  exercise or  conversion of the
Other  Securities)  for a  consideration  per  share  less  than  a  price  (the
"Applicable  Price") equal to the Warrant  Exercise Price in effect  immediately
prior to such issuance or sale,  then  immediately  after such issue or sale the
Warrant  Exercise  Price then in effect  shall be reduced to an amount  equal to
such  consideration per share. Upon each such adjustment of the Warrant Exercise
Price  hereunder,  the number of Warrant  Shares  issuable upon exercise of this
Warrant shall be adjusted to the number of shares  determined by multiplying the
Warrant  Exercise Price in effect  immediately  prior to such  adjustment by the
number of Warrant  Shares  issuable  upon  exercise of this Warrant  immediately
prior to such  adjustment  and  dividing  the  product  thereof  by the  Warrant
Exercise Price resulting from such adjustment.

            (b) Effect on Warrant Exercise Price of Certain Events. For purposes
of determining the adjusted Warrant Exercise Price under Section 8(a) above, the
following shall be applicable:

                  (i)  Issuance  of Options.  Subject to Section  (a) above,  if
after the date  hereof,  the  Company in any manner  grants any  Options and the
lowest price per share for which one share of Common Stock is issuable  upon the
exercise of any such Option or upon  conversion  or exchange of any  convertible
securities issuable upon exercise of any such Option is less than the Applicable
Price,  then such share of Common Stock shall be deemed to be outstanding and to
have been issued and sold by the Company at the time of the  granting or sale of
such Option for such price per share. For purposes of this Section 8(b)(i),  the
lowest  price per share for  which one share of Common  Stock is  issuable  upon
exercise of such  Options or upon  conversion  or  exchange of such  Convertible
Securities shall be equal to the sum of the lowest amounts of consideration  (if
any)  received or  receivable  by the Company  with  respect to any one share of
Common  Stock upon the  granting  or sale of the  Option,  upon  exercise of the
Option or upon conversion or exchange of any convertible  security issuable upon
exercise of such Option.  No further  adjustment of the Warrant  Exercise  Price
shall  be made  upon  the  actual  issuance  of  such  Common  Stock  or of such
convertible  securities  upon the  exercise  of such  Options or upon the actual
issuance of such Common Stock upon  conversion  or exchange of such  convertible
securities.

                  (ii) Issuance of  Convertible  Securities.  Subject to Section
(a)  above,  if the  Company  in any  manner  issues  or sells  any  convertible
securities and the lowest price per share for which one share of Common Stock is
issuable  upon the  conversion or exchange  thereof is less than the  Applicable
Price,  then such share of Common Stock shall be deemed to be outstanding and to
have been issued and sold by the Company at the time of the  issuance or sale of
such  convertible  securities for such price per share. For the purposes of this
Section 8(b)(ii), the lowest price per share for which one share of Common Stock
is issuable upon such  conversion  or exchange  shall be equal to the sum of the
lowest amounts of  consideration  (if any) received or receivable by the Company
with  respect  to one share of Common  Stock  upon the  issuance  or sale of the
convertible  security  and  upon  conversion  or  exchange  of such  convertible
security. No further adjustment of the Warrant Exercise Price shall be made upon
the actual  issuance of such Common  Stock upon  conversion  or exchange of such
convertible  securities,  and if any  such  issue  or sale  of such  convertible
securities  is made upon  exercise of any Options  for which  adjustment  of the
Warrant  Exercise Price had been or are to be made pursuant to other  provisions
of this Section 8(b), no further  adjustment of the Warrant Exercise Price shall
be made by reason of such issue or sale.

                                       8
<PAGE>

                  (iii)  Change in Option  Price or Rate of  Conversion.  If the
purchase price provided for in any Options,  the  additional  consideration,  if
any,  payable  upon  the  issue,  conversion  or  exchange  of  any  convertible
securities, or the rate at which any convertible securities are convertible into
or exchangeable for Common Stock changes at any time, the Warrant Exercise Price
in effect at the time of such change  shall be adjusted to the Warrant  Exercise
Price  which  would  have  been in  effect  at such  time  had such  Options  or
convertible  securities  provided for such changed  purchase  price,  additional
consideration  or  changed  conversion  rate,  as the case  may be,  at the time
initially granted, issued or sold and the number of Warrant Shares issuable upon
exercise of this Warrant shall be  correspondingly  readjusted.  For purposes of
this Section 8(b)(iii),  if the terms of any Option or convertible security that
was  outstanding  as of the  Issuance  Date of this  Warrant  are changed in the
manner  described in the  immediately  preceding  sentence,  then such Option or
convertible  security  and the  Common  Stock  deemed  issuable  upon  exercise,
conversion  or  exchange  thereof  shall be deemed to have been issued as of the
date of such change.  No adjustment  pursuant to this Section 8(b) shall be made
if such  adjustment  would result in an increase of the Warrant  Exercise  Price
then in effect.

            (c) Effect on Warrant Exercise Price of Certain Events. For purposes
of determining the adjusted Warrant Exercise Price under Sections 8(a) and 8(b),
the following shall be applicable:

                  (i)  Calculation  of  Consideration  Received.  If any  Common
Stock,  Options or  convertible  securities are issued or sold or deemed to have
been  issued or sold for cash,  the  consideration  received  therefore  will be
deemed to be the net amount  received  by the Company  therefore.  If any Common
Stock, Options or convertible  securities are issued or sold for a consideration
other than cash, the amount of such  consideration  received by the Company will
be the  fair  value  of such  consideration,  except  where  such  consideration
consists of  marketable  securities,  in which case the amount of  consideration
received by the Company will be the market price of such  securities on the date
of  receipt of such  securities.  If any Common  Stock,  Options or  convertible
securities  are issued to the owners of the  non-surviving  entity in connection
with any merger in which the  Company  is the  surviving  entity,  the amount of
consideration  therefore  will be deemed to be the fair value of such portion of
the net assets and business of the  non-surviving  entity as is  attributable to
such Common Stock,  Options or convertible  securities,  as the case may be. The
fair value of any consideration other than cash or securities will be determined
jointly  by the  Company  and the  holders  of  Warrants  representing  at least
two-thirds (b) of the Warrant Shares issuable upon exercise of the Warrants then
outstanding.  If such parties are unable to reach agreement within ten (10) days
after the occurrence of an event requiring  valuation (the  "Valuation  Event"),
the fair value of such consideration will be determined within five (5) Business
Days after the tenth (10th) day following the Valuation Event by an independent,
reputable  appraiser jointly selected by the Company and the holders of Warrants
representing  at  least  two-thirds  (b) of the  Warrant  Shares  issuable  upon
exercise of the Warrants then  outstanding.  The determination of such appraiser
shall be final and binding  upon all  parties and the fees and  expenses of such
appraiser shall be borne jointly by the Company and the holders of Warrants.

                                       9
<PAGE>

                  (ii) Integrated Transactions.  In case any Option is issued in
connection with the issue or sale of other  securities of the Company,  together
comprising one  integrated  transaction  in which no specific  consideration  is
allocated to such Options by the parties thereto,  the Options will be deemed to
have been issued for a consideration of $.01.

                  (iii)  Treasury  Shares.  The number of shares of Common Stock
outstanding  at any given time does not include  shares  owned or held by or for
the account of the Company,  and the  disposition of any shares so owned or held
will be considered an issue or sale of Common Stock.

                  (iv) Record Date. If the Company takes a record of the holders
of Common Stock for the purpose of  entitling  them (1) to receive a dividend or
other distribution payable in Common Stock, Options or in convertible securities
or (2) to  subscribe  for or  purchase  Common  Stock,  Options  or  convertible
securities,  then such record date will be deemed to be the date of the issue or
sale of the shares of Common  Stock  deemed to have been issued or sold upon the
declaration  of such  dividend or the making of such other  distribution  or the
date of the granting of such right of subscription or purchase,  as the case may
be.

            (d)  Adjustment  of  Warrant  Exercise  Price  upon  Subdivision  or
Combination  of  Common  Stock.  If the  Company  at any time  after the date of
issuance  of this  Warrant  subdivides  (by any  stock  split,  stock  dividend,
recapitalization  or otherwise) one or more classes of its outstanding shares of
Common  Stock into a greater  number of shares,  any Warrant  Exercise  Price in
effect immediately prior to such subdivision will be proportionately reduced and
the number of shares of Common Stock  obtainable  upon  exercise of this Warrant
will be proportionately  increased. If the Company at any time after the date of
issuance  of this  Warrant  combines  (by  combination,  reverse  stock split or
otherwise) one or more classes of its outstanding  shares of Common Stock into a
smaller number of shares, any Warrant Exercise Price in effect immediately prior
to such combination will be proportionately  increased and the number of Warrant
Shares issuable upon exercise of this Warrant will be proportionately decreased.
Any  adjustment  under this Section 8(d) shall become  effective at the close of
business on the date the subdivision or combination becomes effective.

            (e) Distribution of Assets. If the Company shall declare or make any
dividend or other  distribution  of its assets (or rights to acquire its assets)
to holders of Common Stock, by way of return of capital or otherwise (including,
without  limitation,  any  distribution  of cash,  stock  or  other  securities,
property or options by way of a dividend, spin off, reclassification,  corporate
rearrangement  or other similar  transaction)  (a  "Distribution"),  at any time
after the issuance of this Warrant, then, in each such case:

                  (i) any Warrant Exercise Price in effect  immediately prior to
the close of business on the record date fixed for the  determination of holders
of Common Stock entitled to receive the Distribution shall be reduced, effective
as of the close of  business  on such  record  date,  to a price  determined  by
multiplying such Warrant Exercise Price by a fraction of which (A) the numerator
shall  be the  Closing  Sale  Price  of the  Common  Stock  on the  trading  day
immediately  preceding such record date minus the value of the  Distribution (as
determined in good faith by the Company's Board of Directors)  applicable to one
share of Common Stock,  and (B) the denominator  shall be the Closing Sale Price
of the Common Stock on the trading day  immediately  preceding such record date;
and

                                       10
<PAGE>

                  (ii) either (A) the number of Warrant Shares  obtainable  upon
exercise of this  Warrant  shall be increased to a number of shares equal to the
number of shares of Common Stock  obtainable  immediately  prior to the close of
business  on the record  date fixed for the  determination  of holders of Common
Stock entitled to receive the  Distribution  multiplied by the reciprocal of the
fraction set forth in the immediately  preceding clause (i), or (B) in the event
that the  Distribution  is of common  stock of a company  whose  common stock is
traded on a  national  securities  exchange  or a national  automated  quotation
system,  then the holder of this Warrant shall receive an additional  warrant to
purchase  Common  Stock,  the terms of which shall be identical to those of this
Warrant,  except that such warrant shall be  exercisable  into the amount of the
assets that would have been  payable to the holder of this  Warrant  pursuant to
the Distribution had the holder exercised this Warrant immediately prior to such
record date and with an exercise price equal to the amount by which the exercise
price of this Warrant was decreased with respect to the Distribution pursuant to
the terms of the immediately preceding clause (i).

            (f) Certain Events.  If any event occurs of the type contemplated by
the  provisions  of  this  Section  8 but  not  expressly  provided  for by such
provisions  (including,  without limitation,  the granting of stock appreciation
rights,  phantom  stock rights or other rights with equity  features),  then the
Company's Board of Directors will make an appropriate  adjustment in the Warrant
Exercise Price and the number of shares of Common Stock obtainable upon exercise
of this  Warrant so as to protect  the  rights of the  holders of the  Warrants;
provided,  except as set forth in section 8(d),that no such adjustment  pursuant
to this Section 8(f) will  increase the Warrant  Exercise  Price or decrease the
number of shares of Common Stock obtainable as otherwise  determined pursuant to
this Section 8.

            (g) Notices.

                  (i)  Immediately  upon any adjustment of the Warrant  Exercise
Price,  the  Company  will give  written  notice  thereof  to the holder of this
Warrant, setting forth in reasonable detail, and certifying,  the calculation of
such adjustment.

                  (ii) The  Company  will give  written  notice to the holder of
this  Warrant  at least  ten (10) days  prior to the date on which  the  Company
closes  its  books  or  takes a  record  (A) with  respect  to any  dividend  or
distribution   upon  the  Common  Stock,  (B)  with  respect  to  any  pro  rata
subscription  offer to holders of Common Stock or (C) for determining  rights to
vote with  respect to any Organic  Change (as  defined  below),  dissolution  or
liquidation,  provided that such  information  shall be made known to the public
prior to or in conjunction with such notice being provided to such holder.

                  (iii) The Company will also give written  notice to the holder
of this  Warrant at least ten (10) days  prior to the date on which any  Organic
Change,   dissolution  or  liquidation  will  take  place,  provided  that  such
information  shall be made known to the public prior to or in  conjunction  with
such notice being provided to such holder.

      Section   9.   Purchase    Rights;    Reorganization,    Reclassification,
Consolidation, Merger or Sale.

            (a) In addition to any  adjustments  pursuant to Section 8 above, if
at any  time the  Company  grants,  issues  or sells  any  Options,  Convertible
Securities or rights to purchase stock,  warrants,  securities or other property
pro rata to the  record  holders  of any class of Common  Stock  (the  "Purchase
Rights"),  then the holder of this Warrant will be entitled to acquire, upon the
terms  applicable to such Purchase Rights,  the aggregate  Purchase Rights which
such holder could have  acquired if such holder had held the number of shares of
Common Stock  acquirable  upon  complete  exercise of this  Warrant  immediately
before  the date on which a record is taken for the grant,  issuance  or sale of
such Purchase  Rights,  or, if no such record is taken, the date as of which the
record holders of Common Stock are to be determined for the grant, issue or sale
of such Purchase Rights.

                                       11
<PAGE>

      (b) Any recapitalization, reorganization, reclassification, consolidation,
merger,  sale of all or  substantially  all of the  Company's  assets to another
Person or other  transaction  in each case which is  effected in such a way that
holders  of Common  Stock are  entitled  to  receive  (either  directly  or upon
subsequent  liquidation)  stock,  securities  or assets  with  respect  to or in
exchange for Common Stock is referred to herein as an "Organic Change." Prior to
the  consummation of any (i) sale of all or  substantially  all of the Company's
assets to an acquiring  Person or (ii) other Organic Change  following which the
Company is not a  surviving  entity,  the  Company  will  secure from the Person
purchasing  such assets or the successor  resulting from such Organic Change (in
each case,  the "Acquiring  Entity") a written  agreement (in form and substance
satisfactory to the holders of Warrants  representing at least  two-thirds (iii)
of the Warrant Shares  issuable upon exercise of the Warrants then  outstanding)
to deliver to each holder of Warrants in exchange for such Warrants,  a security
of the Acquiring Entity evidenced by a written instrument  substantially similar
in form and  substance  to this Warrant and  satisfactory  to the holders of the
Warrants  (including an adjusted  warrant  exercise price equal to the value for
the Common Stock reflected by the terms of such  consolidation,  merger or sale,
and exercisable for a corresponding  number of shares of Common Stock acquirable
and receivable  upon exercise of the Warrants  without regard to any limitations
on  exercise,  if the value so  reflected  is less than any  Applicable  Warrant
Exercise Price immediately prior to such  consolidation,  merger or sale). Prior
to the  consummation  of any  other  Organic  Change,  the  Company  shall  make
appropriate  provision  (in form and  substance  satisfactory  to the holders of
Warrants representing a majority of the Warrant Shares issuable upon exercise of
the  Warrants  then  outstanding)  to  insure  that each of the  holders  of the
Warrants will  thereafter have the right to acquire and receive in lieu of or in
addition  to (as the case may be) the  Warrant  Shares  immediately  theretofore
issuable and  receivable  upon the exercise of such holder's  Warrants  (without
regard to any  limitations  on  exercise),  such shares of stock,  securities or
assets  that would  have been  issued or payable  in such  Organic  Change  with
respect to or in exchange for the number of Warrant Shares which would have been
issuable and  receivable  upon the exercise of such  holder's  Warrant as of the
date of such Organic  Change  (without  taking into account any  limitations  or
restrictions on the exercisability of this Warrant).

      Section 10. Lost, Stolen,  Mutilated or Destroyed Warrant. If this Warrant
is lost, stolen,  mutilated or destroyed, the Company shall promptly, on receipt
of an indemnification  undertaking (or, in the case of a mutilated Warrant,  the
Warrant),  issue a new Warrant of like denomination and tenor as this Warrant so
lost, stolen, mutilated or destroyed.

      Section 11. Notice. Any notices, consents, waivers or other communications
required or  permitted  to be given under the terms of this  Warrant  must be in
writing  and will be deemed  to have  been  delivered:  (i) upon  receipt,  when
delivered  personally;  (ii)  upon  receipt,  when sent by  facsimile  (provided
confirmation  of  receipt is  received  by the  sending  party  transmission  is
mechanically or electronically generated and kept on file by the sending party);
or (iii) one Business Day after deposit with a nationally  recognized  overnight
delivery  service,  in each case properly  addressed to the party to receive the
same. The addresses and facsimile numbers for such communications shall be:

      Section 13. Amendment and Waiver. Except as otherwise provided herein, the
provisions  of the  Warrants  may be amended and the Company may take any action
herein prohibited, or omit to perform any act herein required to be performed by
it,  only if the  Company has  obtained  the  written  consent of the holders of

      Section 14. Descriptive Headings;  Governing Law. The descriptive headings
of the  several  sections  and  paragraphs  of this  Warrant  are  inserted  for

laws of the State of New Jersey shall govern all issues  concerning the relative
rights of the Company and its stockholders.  All other questions  concerning the
construction,  validity,  enforcement and interpretation of this Agreement shall
be governed by the  internal  laws of the State of New  Jersey,  without  giving
effect to any choice of law or conflict of law provision or rule (whether of the
State of New Jersey or any other jurisdictions) that would cause the application

connection herewith or therewith, or with any transaction contemplated hereby or
discussed herein, and hereby irrevocably waives, and agrees not to assert in any
suit, action or proceeding,  any claim that it is not personally  subject to the
jurisdiction of any such court,  that such suit, action or proceeding is brought
in an inconvenient forum or that the venue of such suit, action or proceeding is
improper.  Each party hereby  irrevocably waives personal service of process and
consents  to process  being  served in any such suit,  action or  proceeding  by
mailing a copy thereof to such party at the address for such notices to it under
this Agreement and agrees that such service shall constitute good and sufficient
service of process and notice thereof.  Nothing contained herein shall be deemed
to limit in any way any right to serve process in any manner permitted by law.
