                  (vii) By executing this Note Purchase Agreement, the Purchaser
                  hereby  acknowledges  receipt of all such  information  as the
                  Purchaser  deems  necessary  and  appropriate  to  enable  the
                  Purchaser to evaluate  the merits and risks in  acquiring  the

                  and complete  information  covering the business and financial
                  condition of the Company,  including the opportunity to obtain

                  response to all  inquiries in respect  thereof.  The Purchaser
                  has such  knowledge  and  experience in financial and business
                  matters that he is capable of evaluating  the merits and risks
                  of acquiring the Securities and the capacity of protecting its
                  own interests in the transaction;

                  (viii) The  Purchaser  has been  furnished  with the materials
                  relating  to the Company  and the  offering of the  Securities
                  which he has requested,  and has been afforded the opportunity
                  to make  inquiries  concerning the Company and such matters as
                  the  Purchaser  has deemed  necessary,  and has  further  been
                  afforded the opportunity to obtain any additional  information
                  required by the Purchaser to the extent the Company  possesses
                  such  information  or could  acquire it  without  unreasonable
                  effort or expense;

                  (ix) The Purchaser has substantial  means of providing for its
                  current needs and  contingencies and has no need for liquidity
                  in this investment;

                  (x) The Purchaser has  determined  that the  Securities  are a
                  suitable  investment  for it and that it could bear a complete
                  loss of its entire investment;

                  (xi) The Purchaser has relied on its own tax and legal advisor
                  and its own  investment  counselor  with respect to the income
                  tax  and  investment  considerations  of  a  purchase  of  the
                  Securities;

                  (xii) The  Purchaser  did not learn of the offering  described
                  herein through any general  advertising  or other  literature,
                  and it has relied only on the  information  furnished  or made
                  available to them by the Company described above;

                  (xiii) No  representations or warranties have been made to the
                  Purchaser  by  the  Company,   its   officers,   directors  or
                  shareholders  or any persons  acting on behalf of the Company,
                  or  any   affiliates   of  any  of   them,   other   than  the
                  representations set forth herein; and

                  (xiv) The foregoing representations, warranties and agreements
                  of the  Purchaser  shall  survive the sale and issuance of the
                  Securities to the Purchaser.

Irvine, California

         HiEnergy  Technologies,  Inc., a Delaware  corporation  ("Maker"),  for
value received,  hereby promises to pay  ___________,  or order  ("Holder"),  at
__________________  , or at such other place as designated in writing by Holder,
the  principal  sum of  ___________________  Thousand  Dollars  ($______),  with
interest  thereon  at the  rate of five  percent  (5%)  per  annum  on the  then
outstanding  principal  balance  computed  on the  basis of a  365-day  year and
charged on the basis of actual days elapsed. The outstanding  principal balance,
together  with all accrued and unpaid  interest  shall all be due and payable in
full on or before 5:00 p.m.,  California  time,  _________,  2006 (the "Maturity
Date"). All sums payable pursuant hereto shall be payable in lawful money of the
United States of America.  Payments made under this Note shall be first credited

                              TERMS AND CONDITIONS

         Section 1. Prepayment.  Maker may prepay this Note in whole or in part,
without  penalty,  at any time and from  time to time  upon  thirty  days  prior
written notice to Holder (the "Notice").

called individually an "Event of Default") shall occur:

                                       1
<PAGE>

                  (a) If Maker  shall  default  in the  payment of any amount on
this Note when the same shall become due and payable,  whether at maturity or by
acceleration or otherwise, or otherwise default under this Note; or

                  (b) If Maker  shall  make an  assignment  for the  benefit  of
creditors; or

                  (c) If Maker shall file a voluntary petition in bankruptcy, or
shall be  adjudicated  a bankrupt or  insolvent  under the present or any future
Federal Bankruptcy Act or other applicable federal,  state or other statute, law
or regulation; or

                  (d) In the event of a  liquidation,  dissolution or winding up
of the  Maker,  whether  voluntary  or  involuntary,  or a sale,  or a series of
related  sales,  of all or  substantially  all of the assets of the Maker,  or a
sale, or a series of related sales, or exchange,  of capital stock of the Maker,
either by the Maker or its  shareholders,  such  that the  Maker's  shareholders
immediately  before  such  transaction  do not hold (by virtue of such shares or
securities  issued solely with respect thereto) more than fifty percent (50%) of
the  voting  power  of  the  surviving  or  continuing   entity,  or  a  merger,
consolidation,  acquisition of property or shares,  separation or reorganization
of the Maker with one or more entities,  corporate or otherwise,  as a result of
which the  Maker is not the  surviving  corporation  or as a result of which the
holders  of stock of the  Maker as of prior to the  transaction  do not hold (by
virtue of such shares or  securities  issued  solely with respect  thereto) more
than fifty  percent  (50%) of the voting power of the  surviving  or  continuing
entity; or

                  (e) In the event the Maker  redeems,  purchases  or  otherwise
acquires for value,  any share or shares of its equity  securities other than an
aggregate of up to 5% of the then  outstanding  shares  issued to employees  and
consultants of the Maker pursuant to agreements giving the Maker a right or duty
to repurchase  such shares upon  termination  of employment  with the Maker,  or
declares or pays any  dividends  on or declares or makes any other  distribution
(other than a dividend  payable on the Common  Stock  solely in shares of Common
Stock or rights or options to  purchase  Common  Stock) on account of any of its
equity securities or sets apart any sum for any such purpose;

then,  and in each and every such case, the Holder of this Note may by notice in
writing to the Maker declare all amounts under this Note to be forthwith due and
payable  (except that,  in the case of an Event of Default under either  Section
2(b) or Section 2(c), this Note shall become immediately due and payable without
notice) and  thereupon  the balance  shall  become so due and  payable,  without
presentation,  protest or further demand or notice of any kind, all of which are
hereby  expressly  waived.  The Maker  shall give  promptly a written  notice to
Holder of the  occurrence or the approval by the Maker or its Board of Directors
of any and all of the foregoing  events,  and in any of the events under Section
2(d) or Section  2(e),  such notice  shall be given at least  fifteen  (15) days
prior to the anticipated effective date of the transaction. In addition, upon an
Event of Default,  Holder may  exercise  any and all other  rights and  remedies
Holder has at law, in equity or  otherwise.  All  remedies  are  cumulative.  No
single or partial  exercise of Holder of any right  hereunder shall preclude any
other or further exercise thereof or the exercise of any other right.

                                       2
<PAGE>

         Section 3. No Waiver.  No waiver by Holder of any  default of breach by
Maker  under this Note shall be implied  from any delay or omission by Holder to
take action on account of such default if such default  persists or is repeated;
no express waiver shall affect any default other than the default expressly made
the subject of the waiver and any such express  waiver  shall be operative  only
for the time and to the extent therein stated. Any waiver of any covenant,  term
or  condition  contained  herein  shall  not be  construed  as a  waiver  of any
subsequent  breach of the same  covenant,  term or  condition.  The  consent  or
approval  by  Holder  to or of any act by Maker  requiring  further  consent  or
approval  shall  not be deemed to waive or render  unnecessary  the  consent  or
approval to or of any subsequent similar act.

         Section 4.  Collection  Costs.  Maker  covenants that, upon an Event of
Default,  it shall pay to the person  entitled  to  receive  such  payment  such
further amount,  to the extent lawful,  as shall be sufficient to cover the cost
and expense of collection  and  enforcement of this Note,  including  reasonable
attorneys' fees and costs,  court costs, costs of appeal and costs of collection
and enforcement of any judgment.

         Section 5.  Successors/Liability.  This Note shall be binding  upon the
heirs,  successors and assigns of Maker and shall inure to the benefit of Holder
and its successor and assigns. Diligence, demand, notice, presentment, notice of
intent to  accelerate  the maturity of this Note are waived by Maker.  This Note
shall be governed by and construed in  accordance  with the laws of the State of
New York.

         Section 6. Compliance with Law. It is Maker's and Holder's intention to
comply with any applicable usury law. In furtherance of this intention of Holder
and Maker, all agreements between Maker and Holder are expressly limited so that
in no event  whatsoever shall the amount paid or agreed to be paid to Holder for
the use,  forbearance  or  detention of money under this Note exceed the maximum
permissible under applicable law. If, for any reason whatsoever,  fulfillment of
any provision  hereof shall be prohibited by law, the obligation to be fulfilled
shall be  reduced to the  maximum  amount so  prohibited,  and if for any reason
Holder should have received as interest an amount which would exceed the highest
lawful  rate,  such amount  which would be in excess of the  permitted  interest
shall, at Holder's option, be applied to the reduction of principal of this Note
and not to the payment of  interest,  or be refunded  to Maker.  This  provision
shall control any other provision of all agreements between Maker and Holder.

         Section 7. Transfer.  Subject to the  restrictions  and  limitations on
transfer under federal or state securities laws, upon surrender of this Note for
transfer or exchange,  a new Note or new Notes of the same tenor, dated the date
to which  interest  has been paid on the  surrendered  Note and in an  aggregate
principal   amount  equal  to  the  unpaid  principal  amount  of  the  Note  so
surrendered,  will be issued to and  registered in the name of the transferee or
transferees.

                                       3
<PAGE>

         Section 8. Note Register. This Note is transferable only upon the books
of the Maker that Maker shall maintain for such purpose. The Maker may treat the
registered  holder of this Note as he or it appears on the Maker's  books at any
time as the Holder for all purposes.

         Section 9. Loss,  Etc., of Note. Upon receipt of evidence  satisfactory
to the Maker of the loss, theft,  destruction or mutilation of this Note, and of
indemnity reasonably satisfactory to the Maker if lost, stolen or destroyed, and
upon  surrender  and  cancellation  of this Note if  mutilated,  the Maker shall
execute  and  deliver  to  the  Holder  a new  Note  of  like  date,  tenor  and
denomination.

         Section 10. Authorization. Maker represents and warrants to Holder that
the  undersigned  are duly  elected and acting  officers  of Maker,  holding the
offices  indicated below, and duly and validly  authorized by the Maker's Bylaws
to execute  and  deliver  and cause the Maker to perform  this Note  without any
further corporate action.

         Section 11. Conversion. The Holder shall have the right to convert (the
"Conversion  Right"),  on the terms and conditions  hereinafter  set forth,  the
principal amount and accrued interest,  costs or other charges of this Note that
is then  outstanding,  in whole or in part,  into a number  of  shares of Common
Stock,  $.001 par value  ("Stock") of the Maker equal to the result  obtained by
dividing the  principal  amount of the Note then  outstanding  by No Dollars and
Forty-five  Cents  ($0.45),  subject  to  adjustment  as  described  below  (the
"Conversion  Price").  The period  during  which the Holder shall be entitled to
elect to convert this Note then outstanding,  or any portion thereof, into Stock
of Maker pursuant hereto shall be from the date of this Note until the latter of
the date set for  prepayment  by the Notice or the date of  Holder's  receipt of
payment of this Note (the  "Conversion  Period").  If Holder  fails to make such
election to convert the then  outstanding  principal amount of this Note, in the
manner hereinafter set forth, within the Conversion Period, the Conversion Right
granted  hereunder shall terminate  automatically  and be of no further force or
effect with  respect to the portion of this Note so repaid.  In the event Notice
is withdrawn by Maker prior to payment, or for any reason payment is not made on
the date set in the Notice,  the Conversion  Right granted under this Section 11
shall not  terminate  and,  the Holder  shall  again have the  Conversion  Right
granted  under this Section with  respect to the  principal  amount of this Note
then outstanding.  If the Holder desires to convert all or part of this Note, on
the terms set forth in this Section,  into Stock,  then,  during the  Conversion
Period,  the Holder must give written notice to Maker of such Holder's  election
to convert this Note as aforesaid,  which election shall be  irrevocable.  Then,
the Maker will  cause one or more stock  certificates  evidencing  the  Holder's
ownership  of the  number of  Conversion  Shares  into  which this Note has been
converted as aforesaid to be delivered  promptly to the Holder against surrender
to Maker of the  original of this Note or a  replacement  for a lost,  stolen or
destroyed  Note. The Maker shall cause the Conversion  Price to be adjusted from
time to time in case Maker  shall (i) pay a dividend  or other  distribution  of
shares of the Stock to the  holders of the  outstanding  shares of such class of
Stock,  (ii) subdivide the  outstanding  shares of the class of Stock into which
this Note is  convertible  into a greater  number of shares,  (iii)  combine the
outstanding  shares of Stock into which this Note is convertible  into a smaller
number of shares, or (iv) merge or otherwise reorganize or reclassify the Stock.
In  the  event  of  each  of the  foregoing,  the  Conversion  Price  in  effect
immediately  prior  thereto  shall be  adjusted  so that the  Holder of the Note
thereafter surrendered for conversion shall be entitled to receive the number of

                                       4
<PAGE>

shares of Stock, or other shares or property,  which he would have owned or have
been entitled to receive had the Note been  converted  immediately  prior to the
happening of such event at the same aggregate  Conversion  Price.  An adjustment
made  pursuant to this Section  shall  become  effective  immediately  after the
record date in the case of a dividend or distribution and shall become effective
immediately  after the effective date in the case of subdivision or combination.
Such adjustments will be made  sequentially  upon the happening of more than one
of the events  described above. In the event the Issuer at any time or from time
to time after the Closing  shall issue any  options or  convertible  securities,
then the  maximum  number of shares  (as set  forth in the  instrument  relating
thereto  without  regard to any  provisions  contained  therein for a subsequent
adjustment  of such number) of Common Stock  issuable  upon the exercise of such
options or, in the case of  convertible  securities and options  therefore,  the
conversion or exchange of such convertible securities, shall be deemed to be New
Shares of Common Stock issued as of the time of such issue, provided that in any
such case in which  New  Shares of Common  Stock  are  deemed to be  issued,  no
further  adjustment to the Conversion Price shall be made pursuant to Section 11
upon the subsequent  issue of  convertible  securities or shares of Common Stock
upon the exercise of such options or conversion or exchange of such  convertible
securities.

12. Ownership Cap and Certain Conversion Restrictions.

         Notwithstanding  any  other  provision  hereof  or of the  Amended  and
Restated  Note  Purchase  Agreement  dated as of January  28,  2004  between the
Company and the Holder (the "Note Purchase Agreement"),  in no event (except (i)
as specifically provided herein as an exception to this provision, or (ii) while
there  is  outstanding  a  tender  offer  for  any or all of the  shares  of the
Company's  Common  Stock,  or (iii)  after the  Maturity  Date or any  notice of
prepayment) shall the Holder be entitled to convert any portion of this Note, or
shall the  Company  have the  obligation  to convert  such Note (and the Company
shall not have the right to pay  interest  hereon in shares of Common  Stock) to
the  extent  that,  after such  conversion  or  issuance  of stock in payment of
interest, the sum of (1) the number of shares of Common Stock beneficially owned
by the Holder and its affiliates (other than shares of Common Stock which may be
deemed  beneficially  owned through the ownership of the unconverted  portion of
the Notes or other  convertible  securities  or of the  unexercised  portion  of
warrants or other rights to purchase Common Stock), and (2) the number of shares
of Common Stock  issuable upon the conversion of the Notes with respect to which
the  determination  of this proviso is being made,  would  result in  beneficial
ownership by the Holder and its affiliates of more than 4.99% of the outstanding
shares of Common Stock (after taking into account the shares to be issued to the
Holder upon such  conversion).  For  purposes of the proviso to the  immediately
preceding sentence,  beneficial ownership shall be determined in accordance with
Section  12 of the  Securities  Exchange  Act of 1934,  as  amended,  except  as
otherwise provided in clause (1) of such sentence. The Holder, by its acceptance
of this Note,  further agrees that if the Holder transfers or assigns any of the
Notes to a party who or which would not be considered  such an  affiliate,  such
assignment  shall be made subject to the  transferee's  or  assignee's  specific
agreement to be bound by the provisions of this Section 12 as if such transferee
or assignee were the original  Holder hereof.  Nothing herein shall preclude the
Holder from  disposing  of a  sufficient  number of other shares of Common Stock
beneficially  owned by the  Holder  so as to  thereafter  permit  the  continued
conversion of this Note.

effectuated  by faxing a Notice of Conversion  (as defined below) to the Company

the Holder of this Note and shall  evidence such  Holder's  intention to convert
this Note or a specified portion hereof. No fractional shares of Common Stock or
scrip  representing  fractions of shares will be issued on  conversion,  but the
number of shares issuable shall be rounded to the nearest whole share.  The date

to be the date on which the Holder  faxes or otherwise  delivers the  conversion
notice  ("Notice  of  Conversion")  to the Company so that it is received by the
Company on or before such  specified  date,  provided  that, if such  conversion
would  convert the entire  remaining  principal  of this Note,  the Holder shall
deliver to the Company the original Notes being converted no later than five (5)
business days thereafter.  Facsimile  delivery of the Notice of Conversion shall
be accepted by the Company at facsimile number (949) 757-1477,  Attn: Secretary,
provided  a copy is sent  on the  same  date to  (949)______,  Attn:  Bogdan  C.
Maglich,  Chairman.  The Company  may change the  recipients,  addresses  or fax
numbers  for such  notices by giving  notice in  writing to Holder  from time to
time.  Certificates  representing  Common  Stock  upon  conversion  ("Conversion
Certificates")  will be delivered to the Holder at the address  specified in the
Notice  of  Conversion  (which  may be  the  Holder's  address  for  notices  as
contemplated by the Note Purchase Agreement or a different address), via express
courier,  by  electronic  transfer or  otherwise,  within five (5) business days
(such fifth  business  day,  the  "Delivery  Date")  after the date on which the
Notice of Conversion is delivered to the Company as contemplated in this Section
13. The Holder shall be deemed to be the holder of the shares  issuable to it in
accordance with the provisions of this Section 13 on the Conversion Date.

         IN WITNESS WHEREOF,  Maker has caused this Note No.__ to be executed as
of the date set forth above.

for issuance  upon exercise of this Warrant or as otherwise  provided  hereunder
require registration or qualification with any governmental  authority under any
federal or state law before such shares may be so issued,  the Issuer will, upon
notice from the Holder of such  requirement,  in good faith use its best efforts
as  expeditiously  as  possible  at its  expense to cause such shares to be duly
registered or qualified.  If the Issuer shall list any shares of Common Stock on
any  securities  exchange  or  market it will,  at its  expense,  list  thereon,
maintain and increase when necessary  such listing,  of, all Warrant Shares from
time to time  issued  upon  exercise of this  Warrant or as  otherwise  provided
hereunder,  and,  to the  extent  permissible  under the  applicable  securities
exchange  rules,  all unissued  Warrant  Shares  which are at any time  issuable
hereunder,  so long as any shares of Common Stock shall be so listed. The Issuer
will also so list on each securities  exchange or market, and will maintain such
listing  of,  any other  securities  which the Holder of this  Warrant  shall be
entitled  to  receive  upon  the  exercise  of this  Warrant  if at the time any
securities  of the same class  shall be listed on such  securities  exchange  or
market by the Issuer.

         (c) Covenants. The Issuer shall not by any action,  including,  without
limitation,  amending the  Certificate  of  Incorporation  or the by-laws of the
Issuer,  or through  any  reorganization,  transfer  of  assets,  consolidation,
merger,  dissolution,  issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such  actions as may be  necessary  or  appropriate  to
protect  the  rights  of the  Holder  hereof  against  dilution  (to the  extent
specifically provided herein) or impairment.  Without limiting the generality of
the  foregoing,  the Issuer  will (i) not permit the par value,  if any,  of its
Common  Stock to exceed  the then  effective  Warrant  Price,  (ii) not amend or
modify any  provision  of the  Certificate  of  Incorporation  or by-laws of the
Issuer in any manner  that would  adversely  affect the rights of the Holders of
the Warrants, (iii) take all such action as may be reasonably necessary in order
that the Issuer may  validly  and  legally  issue  fully paid and  nonassessable
shares of Common Stock,  free and clear of any liens,  claims,  encumbrances and
restrictions  (other than as provided herein) upon the exercise of this Warrant,
and (iv) use its best efforts to obtain all such  authorizations,  exemptions or
consents from any public regulatory body having  jurisdiction  thereof as may be
reasonably  necessary to enable the Issuer to perform its obligations under this
Warrant.

<PAGE>

         (d) Loss,  Theft,  Destruction  of  Warrants.  Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft,  destruction
or  mutilation  of any  Warrant  and,  in the  case of any such  loss,  theft or
destruction,  upon receipt of indemnity or security  satisfactory  to the Issuer
or, in the case of any such mutilation,  upon surrender and cancellation of such
Warrant,  the  Issuer  will  make and  deliver,  in lieu of such  lost,  stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

5. Adjustment of Warrant Price and Warrant Share Number. The number of shares of
Common Stock for which this Warrant is exercisable,  and the price at which such
shares may be  purchased  upon  exercise  of this  Warrant,  shall be subject to
adjustment  from time to time as set forth in this  Section 5. The Issuer  shall
give the Holder notice of any event described below which requires an adjustment
pursuant to this Section 5 in accordance with Section 6.

         (a) Recapitalization,  Reorganization, Reclassification, Consolidation,
Merger or Sale.

                  (i) In case the Issuer after the Original  Issue Date shall do
         any of the following (each, a "Triggering Event"): (a) consolidate with
         or  merge  into  any  other  Person  and the  Issuer  shall  not be the
         continuing or surviving corporation of such consolidation or merger, or
         (b)  permit  any other  Person to  consolidate  with or merge  into the
         Issuer and the Issuer shall be the continuing or surviving  Person but,
         in connection with such  consolidation or merger,  any Capital Stock of
         the Issuer  shall be changed into or exchanged  for  Securities  of any
         other  Person or cash or any other  property,  or (c)  transfer  all or
         substantially  all of its properties or assets to any other Person,  or
         (d) effect a capital  reorganization or reclassification of its Capital
         Stock,  then,  and in the case of each such  Triggering  Event,  proper
         provision  shall be made so that,  upon the  basis and the terms and in
         the manner  provided in this Warrant,  the Holder of this Warrant shall
         be entitled upon the exercise hereof at any time after the consummation
         of such  Triggering  Event, to the extent this Warrant is not exercised
         prior to such  Triggering  Event,  to receive at the  Warrant  Price in
         effect  at the  time  immediately  prior  to the  consummation  of such
         Triggering  Event  in lieu  of the  Common  Stock  issuable  upon  such
         exercise  of  this  Warrant  prior  to  such  Triggering   Event,   the
         Securities,  cash and  property  to which such  Holder  would have been
         entitled upon the  consummation of such Triggering Event if such Holder
         had exercised the rights represented by this Warrant  immediately prior
         thereto,  subject to adjustments  (subsequent to such corporate action)
         as nearly  equivalent  as  possible  to the  adjustments  provided  for
         elsewhere in this Section 5.

<PAGE>

                  (ii) Notwithstanding anything contained in this Warrant to the
         contrary,  the Issuer will not effect any Triggering Event if, prior to
         the consummation thereof, each Person (other than the Issuer) which may
         be  required  to deliver  any  Securities,  cash or  property  upon the
         exercise of this Warrant as provided  herein shall  assume,  by written
         instrument delivered to, and reasonably  satisfactory to, the Holder of
         this Warrant, (A) the obligations of the Issuer under this Warrant (and
         if the Issuer shall survive the consummation of such Triggering  Event,
         such  assumption  shall be in  addition  to, and shall not  release the
         Issuer  from,  any  continuing  obligations  of the  Issuer  under this
         Warrant) and (B) the  obligation  to deliver to such Holder such shares
         of  Securities,  cash or property as, in accordance  with the foregoing
         provisions  of this  subsection  (a),  such Holder shall be entitled to
         receive,  and such Person shall have similarly delivered to such Holder
         an  opinion  of  counsel  for  such  Person,  which  counsel  shall  be
         reasonably satisfactory to such Holder, stating that this Warrant shall
         thereafter  continue  in full  force and  effect  and the terms  hereof
         (including,   without  limitation,   all  of  the  provisions  of  this
         subsection (a)) shall be applicable to the Securities, cash or property
         which such Person may be required to deliver  upon any exercise of this
         Warrant or the exercise of any rights pursuant hereto.

         (b) Stock Dividends,  Subdivisions and Combinations. If at any time the
Issuer shall:

                  (i) take a record of the  holders of its Common  Stock for the
         purpose of  entitling  them to receive a dividend  payable in, or other
         distribution of, shares of Common Stock,

                  (ii) subdivide its  outstanding  shares of Common Stock into a
         larger number of shares of Common Stock, or

                  (iii)  combine its  outstanding  shares of Common Stock into a
         smaller number of shares of Common Stock,

         then (1) the number of shares of Common Stock for which this Warrant is
exercisable immediately after the occurrence of any such event shall be adjusted
to equal the number of shares of Common Stock which a record  holder of the same
number of  shares  of  Common  Stock  for  which  this  Warrant  is  exercisable
immediately  prior to the  occurrence  of such event would own or be entitled to
receive  after the  happening of such event,  and (2) the Warrant  Price then in
effect  shall  be  adjusted  to  equal  (A) the  Warrant  Price  then in  effect
multiplied  by the number of shares of Common  Stock for which  this  Warrant is
exercisable  immediately  prior to the  adjustment  divided by (B) the number of
shares of Common Stock for which this Warrant is exercisable  immediately  after
such adjustment.

Intentionally Omitted.

<PAGE>

         (d) Form of Warrant  after  Adjustments.  The form of this Warrant need
not be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

         (e)  Escrow  of  Warrant   Shares.   If  after  any  property   becomes
distributable  pursuant to this  Section 5 by reason of the taking of any record
of the holders of Common  Stock,  but prior to the  occurrence  of the event for
which such record is taken, and the Holder exercises this Warrant, any shares of
Common Stock issuable upon exercise by reason of such adjustment shall be deemed
the  last  shares  of  Common   Stock  for  which  this   Warrant  is  exercised
(notwithstanding  any other provision to the contrary herein) and such shares or
other property shall be held in escrow for the Holder by the Issuer to be issued
to the Holder upon and to the extent that the event actually  takes place,  upon
payment of the current Warrant Price. Notwithstanding any other provision to the
contrary herein,  if the event for which such record was taken fails to occur or
is  rescinded,  then such  escrowed  shares shall be cancelled by the Issuer and
escrowed property returned.

6. Notice of  Adjustments.  Whenever the Warrant  Price or Warrant  Share Number
shall be adjusted  pursuant to Section 5 hereof (for purposes of this Section 6,
each an  "adjustment"),  the Issuer shall cause its Chief  Financial  Officer to
prepare and execute a certificate setting forth, in reasonable detail, the event
requiring the adjustment, the amount of the adjustment, the method by which such
adjustment  was  calculated  (including a description  of the basis on which the
Board made any determination hereunder), and the Warrant Price and Warrant Share
Number after giving  effect to such  adjustment,  and shall cause copies of such
certificate  to be delivered to the Holder of this Warrant  promptly  after each
adjustment.  Any dispute  between the Issuer and the Holder of this Warrant with
respect to the  matters set forth in such  certificate  may at the option of the
Holder of this  Warrant be submitted  to one of the  national  accounting  firms
currently  known as the "big five"  selected  by the Holder,  provided  that the
Issuer shall have ten (10) days after  receipt of notice from such Holder of its
selection of such firm to object thereto, in which case such Holder shall select
another such firm and the Issuer shall have no such right of objection. The firm
selected by the Holder of this  Warrant as provided  in the  preceding  sentence
shall be  instructed  to  deliver a written  opinion  as to such  matters to the
Issuer and such Holder  within  thirty (30) days after  submission to it of such
dispute. Such opinion shall be final and binding on the parties hereto.

7. Fractional  Shares. No fractional Warrant Shares will be issued in connection
with and exercise  hereof,  but in lieu of such  fractional  shares,  the Issuer
shall  make a cash  payment  therefor  equal in  amount  to the  product  of the
applicable fraction multiplied by the Per Share Market Value then in effect.

8. Call.  Notwithstanding  anything herein to the contrary,  commencing any time
during the effectiveness of the registration  statement  registering the Warrant
SharesRegistration  Statement,  the Issuer,  at its  option,  may call up to one
hundred  percent  (100%) of this  Warrant if the Per Share  Market  Value of the
Common  Stock has been equal to or greater  than $2.50 per share for a period of
five (5) consecutive  Trading Days immediately  prior to the date of delivery of
the Call Notice (a "Call Notice Period") by providing the Holder of this Warrant
written  notice  pursuant  to  Section 13 (the  "Call  Notice").  The rights and

<PAGE>

privileges  granted  pursuant to this Warrant with respect to the Warrant Shares
subject to the Call Notice (the  "Called  Warrant  Shares")  shall expire on the
twentieth  (20th) day after the Holder  receives  the Call  Notice  (the  "Early
Termination  Date") if this Warrant is not exercised with respect to such Called
Warrant Shares prior to such Early  Termination  Date. In the event this Warrant
is not exercised  with respect to the Called  Warrant  Shares,  the Issuer shall
remit to the Holder of this Warrant (i) $.01 per Called Warrant Share and (ii) a
new Warrant  representing the number of Warrant Shares,  if any, which shall not
have been subject to the Call Notice upon the Holder tendering to the Issuer the
applicable Warrant certificate.

9. Ownership Cap and Certain Exercise Restrictions.

         (a) Notwithstanding anything to the contrary set forth in this Warrant,
at no time may a holder of this Warrant  exercise  this Warrant if the number of
shares of Common Stock to be issued pursuant to such exercise would exceed, when
aggregated  with all other  shares of Common  Stock owned by such holder at such
time,  the number of shares of Common  Stock which  would  result in such holder
owning more than  4.999% of all of the Common  Stock  outstanding  at such time;
provided,  however, that upon a holder of this Warrant providing the Issuer with
sixty-one (61) days notice (pursuant to Section 13 hereof) (the "Waiver Notice")
that such holder would like to waive this Section 9(a) with regard to any or all
shares of Common Stock issuable upon exercise of this Warrant, this Section 9(a)
will be of no force or effect  with  regard to all or a portion  of the  Warrant
referenced in the Waiver Notice; provided, further, that this provision shall be
of no  further  force or effect  during  the  sixty-one  (61)  days  immediately
preceding the expiration of the term of this Warrant;  provided,  further,  that
the Holder shall be entitled to waive this  provision  immediately in connection
with the exercise of this Warrant with respect to Called Warrant Shares.

         (b) The Holder may not  exercise  the Warrant  hereunder  to the extent
such exercise would result in the Holder  beneficially  owning (as determined in
accordance  with Section 13(d) of the Exchange Act and the rules  thereunder) in
excess of 9.999% of the then  issued  and  outstanding  shares of Common  Stock,
including  shares issuable upon exercise of the Warrant held by the Holder after
application  of this  Section;  provided,  however,  that  upon a holder of this
Warrant  providing  the Company with a Waiver Notice that such holder would like
to waive this  Section  9(b) with  regard to any or all  shares of Common  Stock
issuable upon  exercise of this Warrant,  this Section 9(b) shall be of no force
or effect with regard to those Warrant  Shares  referenced in the Waiver Notice;
provided,  further,  that this provision  shall be of no further force or effect
during the sixty-one (61) days immediately  preceding the expiration of the term
of this Warrant;  provided,  further, that the Holder shall be entitled to waive
this provision  immediately in connection with the exercise of this Warrant with
respect to Called Warrant Shares.

10. Other Notices. In case at any time:

<PAGE>

         (a) the Issuer  shall make any  distributions  to the holders of Common
Stock; or

         (b) the Issuer  shall  authorize  the  granting  to all  holders of its
Common Stock of rights to subscribe  for or purchase any shares of Capital Stock
of any class or other rights; or

         (c) there shall be any  reclassification  of the  Capital  Stock of the
Issuer; or

         (d) there shall be any capital reorganization by the Issuer; or

         (e) there shall be any (i) consolidation or merger involving the Issuer
or (ii) sale,  transfer or other  disposition of all or substantially all of the
Issuer's property,  assets or business (except a merger or other  reorganization
in which the Issuer shall be the surviving corporation and its shares of Capital
Stock shall continue to be outstanding and unchanged and except a consolidation,
merger,   sale,   transfer  or  other   disposition   involving  a  wholly-owned
Subsidiary); or

         (f) there shall be a voluntary or involuntary dissolution,  liquidation
or  winding-up  of the  Issuer  or any  partial  liquidation  of the  Issuer  or
distribution to holders of Common Stock;

then, in each of such cases,  the Issuer shall give written notice to the Holder
of the date on which (i) the books of the Issuer  shall close or a record  shall
be taken for such dividend,  distribution  or  subscription  rights or (ii) such
reorganization,    reclassification,    consolidation,    merger,   disposition,
dissolution,  liquidation or  winding-up,  as the case may be, shall take place.
Such notice also shall  specify the date as of which the holders of Common Stock
of record shall  participate  in such  dividend,  distribution  or  subscription
rights, or shall be entitled to exchange their certificates for Common Stock for
securities   or   other   property   deliverable   upon   such   reorganization,
reclassification,  consolidation, merger, disposition,  dissolution, liquidation
or  winding-up,  as the case may be. Such notice  shall be given at least twenty
(20) days prior to the action in  question  and not less than  twenty  (20) days
prior to the record date or the date on which the  Issuer's  transfer  books are
closed in  respect  thereto.  The  Holder  shall  have the right to send two (2)
representatives  selected  by it to each  meeting,  who  shall be  permitted  to
attend, but not vote at, such meeting and any adjournments thereof. This Warrant
entitles the Holder to receive  copies of all  financial  and other  information
distributed or required to be distributed to the holders of the Common Stock.

11.  Amendment and Waiver.  Any term,  covenant,  agreement or condition in this
Warrant may be amended, or compliance  therewith may be waived (either generally
or in a particular  instance and either  retroactively or  prospectively),  by a
written  instrument  or  written  instruments  executed  by the  Issuer  and the
Majority  Holders;  provided,  however,  that no such  amendment or waiver shall
reduce the Warrant Share Number,  increase the Warrant Price, shorten the period
during  which this  Warrant may be  exercised  or modify any  provision  of this
Section 11 except with the consent of the Holder of this  Warrant or pursuant to
this Warrant Agreement.
