                     CHINA UNISTONE ACQUISITION CORPORATION
                                                                           CUSIP
                                     WARRANT

                     THIS CERTIFIES THAT, for value received

is the registered holder of a Warrant or Warrants expiring  ________,  2008 (the
"Warrant") to purchase one fully paid and non-assessable  share of Common Stock,
par  value  $.0001  per  share   ("Shares"),   of  China  Unistone   Acquisition
Corporation,  a Delaware corporation (the "Company"), for each Warrant evidenced
by this Warrant Certificate. The Warrant entitles the holder thereof to purchase
from the Company, commencing on the later of (i) the consummation by the Company
of a merger, capital stock exchange, asset acquisition or other similar business
combination or (ii)  __________,  2005,  such number of Shares of the Company at
the price of $5.00 per share,  upon  surrender of this Warrant  Certificate  and
payment  of the  Warrant  Price at the  office or agency of the  Warrant  Agent,
Continental  Stock  Transfer & Trust  Company  (such payment to be made by check
made payable to the Warrant Agent), but only subject to the conditions set forth
herein and in the Warrant  Agreement  between the Company and Continental  Stock
Transfer  &  Trust  Company.  The  Warrant  Agreement  provides  that  upon  the
occurrence of certain  events the Warrant Price and the number of Warrant Shares
purchasable  hereunder,  set forth on the face hereof,  may,  subject to certain
conditions,  be  adjusted.  The  term  Warrant  Price  as used  in this  Warrant
Certificate  refers to the price per Share at which  Shares may be  purchased at
the time the Warrant is exercised.

      No fraction of a Share will be issued upon any  exercise of a Warrant.  If
the holder of a Warrant  would be entitled to receive a fraction of a Share upon
any exercise of a Warrant,  the Company shall,  upon such exercise,  round up to
the nearest whole number the number of Shares to be issued to such holder.

      Upon any  exercise of the  Warrant for less than the total  number of full
Shares  provided  for  herein,  there shall be issued to the  registered  holder
hereof or his assignee a new Warrant  Certificate  covering the number of Shares
for which the Warrant has not been exercised.

      Warrant  Certificates,  when  surrendered  at the  office or agency of the
Warrant  Agent by the  registered  holder  hereof in person or by attorney  duly
authorized  in  writing,  may be  exchanged  in the  manner  and  subject to the
limitations  provided  in the  Warrant  Agreement,  but  without  payment of any
service charge, for another Warrant Certificate or Warrant  Certificates of like
tenor and evidencing in the aggregate a like number of Warrants.

      Upon  due  presentment  for   registration  of  transfer  of  the  Warrant
Certificate  at the  office  or  agency  of the  Warrant  Agent,  a new  Warrant
Certificate  or  Warrant  Certificates  of  like  tenor  and  evidencing  in the
aggregate  a like  number  of  Warrants  shall be issued  to the  transferee  in
exchange for this Warrant  Certificate,  subject to the limitations  provided in
the Warrant  Agreement,  without  charge except for any  applicable tax or other
governmental charge.

      The Company and the Warrant Agent may deem and treat the registered holder
as the absolute owner of this Warrant Certificate  (notwithstanding any notation
of ownership  or other  writing  hereon made by anyone),  for the purpose of any
exercise hereof, of any distribution to the registered holder, and for all other
purposes, and neither the Company nor the Warrant Agent shall be affected by any
notice to the contrary.

      This Warrant does not entitle the  registered  holder to any of the rights
of a stockholder of the Company.

      The Company reserves the right to call the Warrant, with the prior consent
of EarlyBirdCapital,  Inc., at any time prior to its exercise,  with a notice of
call in writing to the holders of record of the Warrant,  giving 30 days' notice
of such call at any time after the Warrant becomes  exercisable if the last sale
price of the Shares has been at least $8.50 per share on each of 20 trading days
within any 30 trading day period  ending on the third  business day prior to the
date on which notice of such call is given. The call price of the Warrants is to
be $.01 per Warrant.  Any Warrant  either not  exercised or tendered back to the
Company by the end of the date specified in the notice of call shall be canceled
on the books of the Company and have no further  value  except for the $.01 call
price.

1. Purchase Option.

            THIS CERTIFIES THAT, in  consideration  of $_____ duly paid by or on
behalf of ____________________  ("Holder"), as registered owner of this Purchase
Option,  to  China  Unistone  Acquisition  Corporation  ("Company"),  Holder  is
entitled, at any time or from time to time upon the later of the consummation of
a Business  Combination  or _________,  2005  ("Commencement  Date"),  and at or

consisting  of one share of common  stock of the  Company,  par value $.0001 per
share ("Common Stock"), and two warrants ("Warrant(s)") expiring four years from
the  effective   date   ("Effective   Date")  of  the   registration   statement
("Registration  Statement")  pursuant to which Units are offered for sale to the
public  ("Offering").  Each Warrant is the same as the warrants  included in the
Units  being  registered  for  sale  to the  public  by way of the  Registration
Statement ("Public Warrants") except that the Warrants have an exercise price of
$6.25 per share. If the Expiration  Date is a day on which banking  institutions
are  authorized by law to close,  then this Purchase  Option may be exercised on
the next  succeeding  day which is not such a day in  accordance  with the terms
herein.  During the period ending on the Expiration Date, the Company agrees not
to take any action that would

                                       1
<PAGE>

terminate the Purchase Option. This Purchase Option is initially  exercisable at
$9.90 per Unit so purchased;  provided, however, that upon the occurrence of any
of the events specified in Section 6 hereof, the rights granted by this Purchase
Option,  including  the  exercise  price per Unit and the  number of Units  (and
shares of Common Stock and Warrants) to be received upon such exercise, shall be
adjusted as therein specified.  The term "Exercise Price" shall mean the initial
exercise price or the adjusted exercise price, depending on the context.

2. Exercise.

      2.1 Exercise Form. In order to exercise this Purchase Option, the exercise
form  attached  hereto must be duly  executed and completed and delivered to the
Company,  together with this Purchase  Option and payment of the Exercise  Price
for the Units being purchased  payable in cash or by certified check or official
bank check. If the subscription rights represented hereby shall not be exercised
at or before 5:00 p.m.,  Eastern  time,  on the  Expiration  Date this  Purchase
Option shall become and be void without further force or effect,  and all rights
represented hereby shall cease and expire.

      2.2 Legend.  Each  certificate  for the  securities  purchased  under this
Purchase  Option shall bear a legend as follows unless such securities have been
registered under the Securities Act of 1933, as amended ("Act"):

            "The  securities  represented  by this  certificate  have  not  been
            registered  under the Securities Act of 1933, as amended  ("Act") or
            applicable  state law. The  securities  may not be offered for sale,
            sold  or  otherwise  transferred  except  pursuant  to an  effective
            registration  statement  under the Act, or pursuant to an  exemption
            from registration under the Act and applicable state law."

      2.3 Cashless Exercise.

            2.3.1  Determination  of  Amount.  In  lieu  of the  payment  of the
Exercise Price  multiplied by the number of Units for which this Purchase Option
is  exercisable  (and in lieu of being  entitled  to  receive  Common  Stock and
Warrants) in the manner required by Section 2.1, the Holder shall have the right
(but not the obligation) to convert any  exercisable but unexercised  portion of
this Purchase Option into Units ("Conversion  Right") as follows:  upon exercise
of the  Conversion  Right,  the  Company  shall  deliver to the Holder  (without
payment  by the  Holder of any of the  Exercise  Price in cash)  that  number of
shares of Common Stock and Warrants comprising that number of Units equal to the
quotient  obtained by dividing (x) the "Value" (as defined below) of the portion
of the  Purchase  Option  being  converted  by (y) the Current  Market Value (as
defined  below).  The  "Value"  of the  portion  of the  Purchase  Option  being
converted  shall  equal  the  remainder  derived  from  subtracting  (a) (i) the
Exercise Price  multiplied by (ii) the number of Units underlying the portion of
this Purchase Option being converted from (b) the Current Market Value of a Unit
multiplied by the number of Units  underlying the portion of the Purchase Option
being converted. As used herein, the term "Current Market Value" per Unit at any
date means the remainder  derived from subtracting (x) the exercise price of the
Warrants  multiplied  by the  number of shares of  Common  Stock  issuable  upon
exercise of the Warrants  underlying  one Unit from (y) the Current Market Price
of the  Common  Stock  multiplied  by the  number  of  shares  of  Common  Stock
underlying the Warrants and the Common Stock issuable upon exercise of one Unit.
The  "Current  Market  Price" of a share of Common  Stock  shall mean (i) if the
Common Stock is listed on a national securities exchange or quoted on the Nasdaq
National Market, Nasdaq SmallCap Market or NASD OTC Bulletin Board (or successor
such as the Bulletin Board Exchange), the last sale price of the

                                       2
<PAGE>

Common Stock in the principal trading market for the Common Stock as reported by
the  exchange,  Nasdaq or the NASD, as the case may be; (ii) if the Common Stock
is not listed on a national securities exchange or quoted on the Nasdaq National
Market, Nasdaq SmallCap Market or the NASD OTC Bulletin Board (or successor such
as the Bulletin Board Exchange), but is traded in the residual  over-the-counter
market,  the  closing  bid price for the Common  Stock on the last  trading  day
preceding  the date in question  for which such  quotations  are reported by the
Pink Sheets, LLC or similar publisher of such quotations;  and (iii) if the fair
market value of the Common Stock cannot be determined  pursuant to clause (i) or
(ii) above, such price as the Board of Directors of the Company shall determine,
in good faith.

            2.3.2 Mechanics of Cashless  Exercise.  The Cashless  Exercise Right
may be exercised by the Holder on any business day on or after the  Commencement
Date and not later than the Expiration  Date by delivering  the Purchase  Option
with the duly executed  exercise form attached hereto with the cashless exercise
section  completed to the Company,  exercising  the Cashless  Exercise Right and
specifying  the total number of Units the Holder will purchase  pursuant to such
Cashless Exercise Right.

3. Transfer.

      3.1 General  Restrictions.  The registered Holder of this Purchase Option,
by its acceptance hereof, agrees that it will not sell, transfer, assign, pledge
or  hypothecate  this  Purchase  Option for a period of one year  following  the
Effective  Date to anyone  other  than (i) EBC or an  underwriter  or a selected
dealer in connection  with the Offering,  or (ii) a bona fide officer or partner
of EBC or of any such  underwriter or selected  dealer.  On and after the second
anniversary  of the Effective  Date,  transfers to others may be made subject to
compliance with or exemptions from applicable  securities laws. In order to make
any permitted assignment,  the Holder must deliver to the Company the assignment
form  attached  hereto duly executed and  completed,  together with the Purchase
Option  and  payment  of all  transfer  taxes,  if any,  payable  in  connection
therewith.  The Company  shall within five  business days transfer this Purchase
Option on the books of the Company and shall  execute and deliver a new Purchase
Option  or  Purchase  Options  of  like  tenor  to the  appropriate  assignee(s)
expressly  evidencing  the  right to  purchase  the  aggregate  number  of Units
purchasable hereunder or such portion of such number as shall be contemplated by
any such assignment.

      3.2  Restrictions  Imposed by the Act.  The  securities  evidenced by this
Purchase  Option shall not be  transferred  unless and until (i) the Company has
received  the  opinion of  counsel  for the Holder  that the  securities  may be
transferred  pursuant  to an  exemption  from  registration  under  the  Act and
applicable  state  securities  laws, the availability of which is established to
the reasonable satisfaction of the Company (the Company hereby agreeing that the
opinion  of  Graubard  Miller  shall  be  deemed  satisfactory  evidence  of the
availability  of  an  exemption),   or  (ii)  a  registration   statement  or  a
post-effective   amendment  to  the  Registration  Statement  relating  to  such
securities  has  been  filed  by  the  Company  and  declared  effective  by the
Securities  and  Exchange   Commission  and  compliance  with  applicable  state
securities law has been established.

4. New Purchase Options to be Issued.

      4.1 Partial Exercise or Transfer. Subject to the restrictions in Section 3
hereof,  this Purchase  Option may be exercised or assigned in whole or in part.
In the event of the exercise or assignment  hereof in part only,  upon surrender
of this  Purchase  Option  for  cancellation,  together  with the duly  executed
exercise or  assignment  form and funds  sufficient  to pay any  Exercise  Price
and/or  transfer  tax,  the Company  shall cause to be  delivered  to the Holder
without  charge a new Purchase  Option of like tenor to this Purchase  Option in
the name of the Holder evidencing the right of the Holder to purchase the number
of Units  purchasable  hereunder as to which this  Purchase  Option has not been
exercised or assigned.

      4.2 Lost Certificate. Upon receipt by the Company of evidence satisfactory
to it of the loss, theft,  destruction or mutilation of this Purchase Option and
of reasonably satisfactory indemnification or the posting of a bond, the Company
shall execute and deliver a new Purchase Option of like tenor and date. Any such
new  Purchase  Option  executed and  delivered as a result of such loss,  theft,
mutilation or destruction shall constitute a substitute  contractual  obligation
on the part of the Company.

5. Registration Rights.

      5.1 Demand Registration.

            5.1.1 Grant of Right.  The Company,  upon written  demand  ("Initial
Demand Notice") of the Holder(s) of at least 51% of the Purchase  Options and/or
the underlying  Units and/or the  underlying  securities  ("Majority  Holders"),
agrees to register on one occasion,  all or any portion of the Purchase  Options
requested by the Majority  Holders in the Initial  Demand  Notice and all of the
securities underlying such Purchase Options,  including the Units, Common Stock,
the Warrants and the Common Stock  underlying  the Warrants  (collectively,  the
"Registrable   Securities").   On  such  occasion,   the  Company  will  file  a
registration  statement  or  a  post-effective  amendment  to  the  Registration
Statement covering the Registrable Securities within sixty days after receipt of
the Initial  Demand  Notice and use its best  efforts to have such  registration
statement or  post-effective  amendment  declared  effective as soon as possible
thereafter.  The demand for registration may be made at any time during a period
of five years beginning on the Effective Date. The Company  covenants and agrees
to give  written  notice of its  receipt  of any  Initial  Demand  Notice by any
Holder(s) to all other  registered  Holders of the Purchase  Options  and/or the
Registrable  Securities within ten days from the date of the receipt of any such
Initial Demand Notice.

            5.1.2 Terms. The Company shall bear all fees and expenses  attendant
to registering the Registrable  Securities,  including the expenses of any legal
counsel selected by the Holders to represent them in connection with the sale of
the Registrable  Securities,  but the Holders shall pay any and all underwriting
commissions. The Company agrees to use its reasonable best efforts to qualify or
register the Registrable  Securities in such States as are reasonably  requested
by the Majority Holder(s); provided, however, that in no event shall the Company
be required  to register  the  Registrable  Securities  in a State in which such
registration  would  cause (i) the  Company  to be  obligated  to  qualify to do
business  in such State,  or would  subject the Company to taxation as a foreign
corporation   doing  business  in  such   jurisdiction  or  (ii)  the  principal
stockholders  of the Company to be  obligated  to escrow their shares of capital
stock of the  Company.  The Company  shall cause any  registration  statement or
post-effective  amendment  filed  pursuant to the demand  rights  granted  under
Section 5.1.1 to remain effective

                                       4
<PAGE>

for a  period  of  nine  consecutive  months  from  the  effective  date of such
registration statement or post-effective amendment.

      5.2 "Piggy-Back" Registration.

            5.2.1  Grant  of  Right.   In  addition  to  the  demand   right  of
registration,  the Holders of the  Purchase  Options  shall have the right for a
period  of  seven  years  commencing  on the  Effective  Date,  to  include  the
Registrable  Securities as part of any other registration of securities filed by
the Company (other than in connection  with a transaction  contemplated  by Rule
145(a)  promulgated under the Act or pursuant to Form S-8);  provided,  however,
that if,  in the  written  opinion  of the  Company's  managing  underwriter  or
underwriters,  if any,  for such  offering,  the  inclusion  of the  Registrable
Securities,  when added to the securities being registered by the Company or the
selling  stockholder(s),  will  exceed  the  maximum  amount  of  the  Company's
securities which can be marketed (i) at a price reasonably related to their then
current market value,  and (ii) without  materially and adversely  affecting the
entire  offering,  then the  Company  will  still be  required  to  include  the
Registrable  Securities,  but may require the Holders to agree,  in writing,  to
delay the sale of all or any portion of the Registrable  Securities for a period
of 90 days from the effective date of the offering,  provided,  further, that if
the  sale of any  Registrable  Securities  is so  delayed,  then the  number  of
securities to be sold by all stockholders in such public offering during such 90
day period shall be  apportioned  pro rata among all such selling  stockholders,
including  all holders of the  Registrable  Securities,  according  to the total
amount  of  securities  of the  Company  owned  by  said  selling  stockholders,
including all holders of the Registrable Securities.

            5.2.2 Terms. The Company shall bear all fees and expenses  attendant
to registering the Registrable  Securities,  including the expenses of any legal
counsel selected by the Holders to represent them in connection with the sale of
the  Registrable  Securities but the Holders shall pay any and all  underwriting
commissions  related  to the  Registrable  Securities.  In the  event  of such a
proposed registration, the Company shall furnish the then Holders of outstanding
Registrable  Securities  with not less than fifteen days written notice prior to
the proposed date of filing of such registration  statement.  Such notice to the
Holders shall continue to be given for each  applicable  registration  statement
filed  (during the period in which the Purchase  Option is  exercisable)  by the
Company  until  such  time  as all  of  the  Registrable  Securities  have  been
registered and sold. The holders of the  Registrable  Securities  shall exercise
the "piggy-back" rights provided for herein by giving written notice, within ten
days  of the  receipt  of  the  Company's  notice  of its  intention  to  file a
registration statement. The Company shall cause any registration statement filed
pursuant to the above  "piggyback"  rights to remain effective for at least nine
months from the date that the Holders of the  Registrable  Securities  are first
given the opportunity to sell all of such securities.

      5.3 Damages. Should the registration or the effectiveness thereof required
by  Sections  5.1 and 5.2  hereof  be  delayed  by the  Company  or the  Company
otherwise fails to comply with such  provisions,  the Company shall, in addition
to any other equitable or other relief available to the Holder(s), be liable for
any and all  incidental,  special and  consequential  damages  sustained  by the
Holder(s),  including,  but not limited  to, the loss of any profits  that might
have been  received  by the  holder  upon the sale of shares of Common  Stock or
Warrants (and shares of Common Stock  underlying the Warrants)  underlying  this
Purchase Option.

      5.4 General Terms.

            5.4.1 Indemnification.  The Company shall indemnify the Holder(s) of
the  Registrable

                                       5
<PAGE>

Securities to be sold pursuant to any registration  statement hereunder and each
person,  if any, who controls  such Holders  within the meaning of Section 15 of
the Act or Section  20(a) of the  Securities  Exchange  Act of 1934,  as amended
("Exchange  Act"),  against  all  loss,  claim,  damage,  expense  or  liability
(including all reasonable attorneys' fees and other expenses reasonably incurred
in  investigating,  preparing  or  defending  against  litigation,  commenced or
threatened,  or any claim  whatsoever  whether arising out of any action between
the  underwriter  and the Company or between the underwriter and any third party
or  otherwise)  to which  any of them may  become  subject  under  the Act,  the
Exchange Act or otherwise,  arising from such registration statement but only to
the same extent and with the same effect as the provisions pursuant to which the
Company has agreed to indemnify the  underwriters  contained in Section 5 of the
Underwriting Agreement between the Company, EBC and the other underwriters named
therein dated the Effective Date. The Holder(s) of the Registrable Securities to
be sold  pursuant  to such  registration  statement,  and their  successors  and
assigns, shall severally,  and not jointly,  indemnify the Company, its officers
and  directors  and each person,  if any,  who  controls the Company  within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange  Act,  against
all  loss,  claim,  damage,  expense  or  liability  (including  all  reasonable
attorneys'  fees  and  other  expenses  reasonably  incurred  in  investigating,
preparing or defending  against any claim  whatsoever)  to which they may become
subject under the Act, the Exchange Act or otherwise,  arising from  information
furnished by or on behalf of such Holders,  or their  successors or assigns,  in
writing,  for  specific  inclusion  in such  registration  statement to the same
extent and with the same effect as the provisions  contained in Section 5 of the
Underwriting  Agreement  pursuant  to which  the  underwriters  have  agreed  to
indemnify the Company.

            5.4.2  Exercise  of  Purchase  Options.  Nothing  contained  in this
Purchase  Option shall be construed as requiring the Holder(s) to exercise their
Purchase Options or Warrants  underlying such Purchase Options prior to or after
the initial filing of any registration statement or the effectiveness thereof.

            5.4.3 Documents Delivered to Holders. The Company shall furnish EBC,
as  representative  of  the  Holders  participating  in  any  of  the  foregoing
offerings, a signed counterpart,  addressed to the participating Holders, of (i)
an  opinion  of  counsel  to the  Company,  dated  the  effective  date  of such
registration  statement  (and,  if such  registration  includes an  underwritten
public offering, an opinion dated the date of the closing under any underwriting
agreement related thereto), and (ii) a "cold comfort" letter dated the effective
date of such  registration  statement  (and,  if such  registration  includes an
underwritten  public offering,  a letter dated the date of the closing under the
underwriting  agreement) signed by the independent  public  accountants who have
issued  a  report  on  the  Company's  financial  statements  included  in  such
registration  statement,  in each case covering  substantially  the same matters
with  respect  to such  registration  statement  (and  the  prospectus  included
therein) and, in the case of such  accountants'  letter,  with respect to events
subsequent to the date of such financial statements,  as are customarily covered
in  opinions  of  issuer's  counsel and in  accountants'  letters  delivered  to
underwriters in underwritten  public offerings of securities.  The Company shall
also deliver promptly to EBC, as representative of the Holders  participating in
the offering, the correspondence and memoranda described below and copies of all
correspondence  between the Commission and the Company,  its counsel or auditors
and all memoranda  relating to discussions with the Commission or its staff with
respect to the registration  statement and permit EBC, as  representative of the
Holders, to do such investigation,  upon reasonable advance notice, with respect
to  information  contained in or omitted from the  registration  statement as it
deems reasonably necessary to comply with applicable securities laws or rules of
the  National   Association  of  Securities   Dealers,   Inc.   ("NASD").   Such
investigation  shall  include  access  to  books,  records  and  properties  and
opportunities  to discuss  the  business of the Company  with its  officers  and
independent auditors, all to such reasonable extent and at such reasonable times
and as often as EBC, as

                                       6
<PAGE>

representative of the Holders,  shall reasonably request.  The Company shall not
be required to disclose any confidential information or other records to EBC, as
representative  of the Holders,  or to any other  person,  until and unless such
persons shall have entered into reasonable  confidentiality  agreements (in form
and substance  reasonably  satisfactory  to the Company),  with the Company with
respect thereto.

            5.4.4  Underwriting  Agreement.  The  Company  shall  enter  into an
underwriting agreement with the managing underwriter(s), if any, selected by any
Holders  whose  Registrable  Securities  are being  registered  pursuant to this
Section 5, which  managing  underwriter  shall be  reasonably  acceptable to the
Company.  Such agreement shall be reasonably  satisfactory in form and substance
to the Company,  each Holder and such managing  underwriters,  and shall contain
such  representations,  warranties  and  covenants by the Company and such other
terms as are  customarily  contained  in  agreements  of that  type  used by the
managing underwriter. The Holders shall be parties to any underwriting agreement
relating to an  underwritten  sale of their  Registrable  Securities and may, at
their  option,  require  that  any or all the  representations,  warranties  and
covenants of the Company to or for the benefit of such  underwriters  shall also
be made to and for the  benefit  of such  Holders.  Such  Holders  shall  not be
required to make any  representations  or warranties  to or agreements  with the
Company or the underwriters  except as they may relate to such Holders and their
intended methods of  distribution.  Such Holders,  however,  shall agree to such
covenants  and   indemnification   and  contribution   obligations  for  selling
stockholders as are customarily contained in agreements of that type used by the
managing  underwriter.  Further,  such Holders shall execute appropriate custody
agreements and otherwise  cooperate fully in the preparation of the registration
statement  and other  documents  relating to any  offering in which they include
securities  pursuant to this  Section 5. Each Holder  shall also  furnish to the
Company such information  regarding itself,  the Registrable  Securities held by
it,  and the  intended  method of  disposition  of such  securities  as shall be
reasonably required to effect the registration of the Registrable Securities.

            5.4.5  Rule 144 Sale.  Notwithstanding  anything  contained  in this
Section 5 to the  contrary,  the Company  shall have no  obligation  pursuant to
Sections 5.1 or 5.2 for the  registration of Registrable  Securities held by any
Holder  (i) where such  Holder  would  then be  entitled  to sell under Rule 144
within any three-month period (or such other period prescribed under Rule 144 as
may be provided by amendment  thereof) all of the  Registrable  Securities  then
held by such Holder, and (ii) where the number of Registrable Securities held by
such Holder is within the volume  limitations  under  paragraph  (e) of Rule 144
(calculated as if such Holder were an affiliate within the meaning of Rule 144).

            5.4.6 Supplemental Prospectus. Each Holder agrees, that upon receipt
of any  notice  from the  Company of the  happening  of any event as a result of
which the prospectus included in the Registration  Statement, as then in effect,
includes  an untrue  statement  of a material  fact or omits to state a material
fact required to be stated therein or necessary to make the  statements  therein
not misleading in light of the  circumstances  then  existing,  such Holder will
immediately  discontinue  disposition of Registrable  Securities pursuant to the
Registration  Statement covering such Registrable Securities until such Holder's
receipt  of the  copies of a  supplemental  or amended  prospectus,  and,  if so
desired by the Company, such Holder shall deliver to the Company (at the expense
of the  Company) or destroy (and  deliver to the Company a  certificate  of such
destruction) all copies,  other than permanent file copies then in such Holder's
possession,  of the prospectus  covering such Registrable  Securities current at
the time of receipt of such notice.

6. Adjustments.

      6.1  Adjustments to Exercise Price and Number of Securities.  The Exercise
Price and the number of Units underlying the Purchase Option shall be subject to
adjustment from time to time as hereinafter set forth:

            6.1.1 Stock  Dividends - Split-Ups.  If after the date  hereof,  and
subject to the provisions of Section 6.4 below, the number of outstanding shares
of Common  Stock is increased  by a stock  dividend  payable in shares of Common
Stock or by a split-up of shares of Common Stock or other similar  event,  then,
on the effective date thereof,  the number of shares of Common Stock  underlying
each of the Units purchasable hereunder shall be increased in proportion to such
increase in  outstanding  shares.  In such case,  the number of shares of Common
Stock,  and the  exercise  price  applicable  thereto,  underlying  the Warrants
underlying  each  of the  Units  purchasable  hereunder  shall  be  adjusted  in
accordance with the terms of the Warrants.  For example, if the Company declares
a  two-for-one  stock  dividend and at the time of such  dividend  this Purchase
Option is for the  purchase  of one Unit at $6.60 per whole Unit  (each  Warrant
underlying the Units is exercisable for $5.00 per share),  upon effectiveness of
the dividend, this Purchase Option will be adjusted to allow for the purchase of
one Unit at $6.60 per Unit, each Unit entitling the holder to receive two shares
of Common  Stock  and four  Warrants  (each  Warrant  exercisable  for $2.50 per
share).

            6.1.2 Aggregation of Shares.  If after the date hereof,  and subject
to the  provisions  of Section 6.4, the number of  outstanding  shares of Common
Stock is decreased by a consolidation, combination or reclassification of shares
of Common Stock or other similar event, then, on the effective date thereof, the
number  of  shares  of Common  Stock  underlying  each of the Units  purchasable
hereunder  shall be  decreased in  proportion  to such  decrease in  outstanding
shares.  In such case,  the number of shares of Common  Stock,  and the exercise
price applicable  thereto,  underlying the Warrants underlying each of the Units
purchasable  hereunder  shall be  adjusted in  accordance  with the terms of the
Warrants.

            6.1.3 Replacement of Securities upon Reorganization, etc. In case of
any reclassification or reorganization of the outstanding shares of Common Stock
other  than a change  covered by Section  6.1.1 or 6.1.2  hereof or that  solely
affects  the par value of such  shares of  Common  Stock,  or in the case of any
merger or consolidation of the Company with or into another  corporation  (other
than  a  consolidation  or  merger  in  which  the  Company  is  the  continuing
corporation and that does not result in any  reclassification  or reorganization
of the  outstanding  shares  of  Common  Stock),  or in the  case of any sale or
conveyance to another corporation or entity of the property of the Company as an
entirety or substantially as an entirety in connection with which the Company is
dissolved,  the Holder of this Purchase  Option shall have the right  thereafter
(until the  expiration  of the right of  exercise  of this  Purchase  Option) to
receive upon the exercise hereof,  for the same aggregate Exercise Price payable
hereunder  immediately  prior to such  event,  the kind and  amount of shares of
stock or other  securities or property  (including  cash)  receivable  upon such
reclassification, reorganization, merger or consolidation, or upon a dissolution
following  any such sale or  transfer,  by a Holder  of the  number of shares of
Common Stock of the Company obtainable upon exercise of this Purchase Option and
the  underlying   Warrants   immediately   prior  to  such  event;  and  if  any
reclassification  also results in a change in shares of Common Stock  covered by
Section 6.1.1 or 6.1.2,  then such adjustment shall be made pursuant to Sections
6.1.1,  6.1.2 and this Section 6.1.3. The provisions of this Section 6.1.3 shall
similarly  apply to successive  reclassifications,  reorganizations,  mergers or
consolidations, sales or other transfers.

                                       8
<PAGE>

            6.1.4  Changes in Form of  Purchase  Option.  This form of  Purchase
Option need not be changed because of any change  pursuant to this Section,  and
Purchase  Options issued after such change may state the same Exercise Price and
the same number of Units as are stated in the Purchase Options  initially issued
pursuant to this Agreement.  The acceptance by any Holder of the issuance of new
Purchase Options  reflecting a required or permissive change shall not be deemed
to waive any rights to an adjustment  occurring after the  Commencement  Date or
the computation thereof.

      6.2 [Intentionally Omitted]

      6.3  Substitute  Purchase  Option.  In  case of any  consolidation  of the
Company  with,  or merger of the Company  with,  or merger of the Company  into,
another  corporation (other than a consolidation or merger which does not result
in  any  reclassification  or  change  of the  outstanding  Common  Stock),  the
corporation  formed by such consolidation or merger shall execute and deliver to
the Holder a  supplemental  Purchase  Option  providing  that the holder of each
Purchase  Option  then  outstanding  or to be  outstanding  shall have the right
thereafter  (until the stated  expiration of such  Purchase  Option) to receive,
upon  exercise of such Purchase  Option,  the kind and amount of shares of stock
and other securities and property  receivable upon such consolidation or merger,
by a holder of the  number of shares of Common  Stock of the  Company  for which
such  Purchase  Option  might  have  been  exercised  immediately  prior to such
consolidation, merger, sale or transfer. Such supplemental Purchase Option shall
provide for adjustments which shall be identical to the adjustments  provided in
Section  6.  The  above  provision  of this  Section  shall  similarly  apply to
successive consolidations or mergers.

      6.4 Elimination of Fractional Interests. The Company shall not be required
to issue  certificates  representing  fractions  of shares  of  Common  Stock or
Warrants upon the exercise of the Purchase  Option,  nor shall it be required to
issue scrip or pay cash in lieu of any fractional interests, it being the intent
of the parties that all fractional interests shall be eliminated by rounding any
fraction up to the nearest  whole number of Warrants,  shares of Common Stock or
other securities, properties or rights.

7.  Reservation  and Listing.  The Company  shall at all times  reserve and keep
available out of its authorized  shares of Common Stock,  solely for the purpose
of issuance upon exercise of the Purchase Options or the Warrants underlying the
Purchase  Option,  such  number of shares of Common  Stock or other  securities,
properties or rights as shall be issuable upon the exercise thereof. The Company
covenants and agrees that, upon exercise of the Purchase  Options and payment of
the Exercise  Price  therefor,  all shares of Common Stock and other  securities
issuable upon such  exercise  shall be duly and validly  issued,  fully paid and
non-assessable  and not subject to  preemptive  rights of any  stockholder.  The
Company  further  covenants  and  agrees  that  upon  exercise  of the  Warrants
underlying the Purchase  Options and payment of the respective  Warrant exercise
price therefor,  all shares of Common Stock and other  securities  issuable upon
such exercise shall be duly and validly  issued,  fully paid and  non-assessable
and not subject to preemptive rights of any stockholder. As long as the Purchase
Options  shall be  outstanding,  the Company shall use its best efforts to cause
all (i) Units and shares of Common Stock  issuable upon exercise of the Purchase
Options,  (iii) Warrants issuable upon exercise of the Purchase Options and (iv)
shares of Common Stock  issuable upon  exercise of the Warrants  included in the
Units  issuable  upon exercise of the Purchase  Option to be listed  (subject to
official  notice of issuance) on all securities  exchanges (or, if applicable on
the Nasdaq National Market, SmallCap Market, OTC Bulletin Board or any successor
trading  market) on which the Units,  the  Common  Stock or the Public  Warrants
issued to the public in connection herewith may then be listed and/or quoted.

8. Certain Notice Requirements.

      8.1 Holder's Right to Receive Notice. Nothing herein shall be construed as
conferring  upon the Holders the right to vote or consent as a  stockholder  for
the  election  of  directors  or any  other  matter,  or as  having  any  rights
whatsoever as a stockholder of the Company.  If,  however,  at any time prior to
the  expiration of the Purchase  Options and their  exercise,  any of the events
described in Section 8.2 shall occur,  then, in one or more of said events,  the
Company  shall give written  notice of such event at least fifteen days prior to
the date fixed as a record  date or the date of closing the  transfer  books for
the determination of the stockholders  entitled to such dividend,  distribution,
conversion or exchange of securities or subscription rights, or entitled to vote
on such proposed dissolution, liquidation, winding up or sale. Such notice shall
specify  such record date or the date of the closing of the transfer  books,  as
the case may be.  Notwithstanding  the  foregoing,  the Company shall deliver to
each Holder a copy of each notice given to the other stockholders of the Company
at the  same  time and in the  same  manner  that  such  notice  is given to the
stockholders.

      8.2 Events  Requiring  Notice.  The Company  shall be required to give the
notice described in this Section 8 upon one or more of the following events: (i)
if the Company  shall take a record of the holders of its shares of Common Stock
for the purpose of entitling them to receive a dividend or distribution  payable
otherwise  than in cash, or a cash dividend or  distribution  payable  otherwise
than out of retained earnings,  as indicated by the accounting treatment of such
dividend or distribution on the books of the Company,  or (ii) the Company shall
offer to all the holders of its Common  Stock any  additional  shares of capital
stock of the Company or securities  convertible  into or exchangeable for shares
of capital  stock of the Company,  or any option,  right or warrant to subscribe
therefor,  or (iii) a  dissolution,  liquidation  or winding  up of the  Company
(other than in connection  with a  consolidation  or merger) or a sale of all or
substantially all of its property, assets and business shall be proposed.

      8.3 Notice of Change in Exercise Price. The Company shall,  promptly after
an event  requiring a change in the Exercise Price pursuant to Section 6 hereof,
send notice to the Holders of such event and change ("Price Notice").  The Price
Notice shall describe the event causing the change and the method of calculating
same and  shall  be  certified  as being  true  and  accurate  by the  Company's
President and Chief Financial Officer.

      8.4  Transmittal  of Notices.  All notices,  requests,  consents and other
communications  under this  Purchase  Option  shall be in  writing  and shall be
deemed to have been duly made when hand delivered,  or mailed by express mail or
private courier service: (i) If to the registered Holder of the Purchase Option,
to the address of such Holder as shown on the books of the  Company,  or (ii) if
to the Company, to the following address or to such other address as the Company
may designate by notice to the Holders:

9. Miscellaneous.

      9.1  Amendments.  The Company and EBC may from time to time  supplement or
amend this Purchase  Option  without the approval of any of the Holders in order
to cure any ambiguity,  to correct or supplement any provision  contained herein
that may be defective or inconsistent  with any other provisions  herein,  or to
make any other  provisions in regard to matters or questions  arising  hereunder
that the Company and EBC may deem  necessary or  desirable  and that the Company
and EBC deem shall not adversely  affect the interest of the Holders.  All other
modifications  or amendments  shall require the written consent of and be signed
by the party  against  whom  enforcement  of the  modification  or  amendment is
sought.

      9.2 Headings.  The headings  contained  herein are for the sole purpose of
convenience  of reference,  and shall not in any way limit or affect the meaning
or interpretation of any of the terms or provisions of this Purchase Option.

10. Entire  Agreement.  This Purchase Option (together with the other agreements
and documents  being  delivered  pursuant to or in connection with this Purchase
Option)  constitutes the entire  agreement of the parties hereto with respect to
the  subject   matter  hereof,   and   supersedes   all  prior   agreements  and
understandings  of the parties,  oral and  written,  with respect to the subject
matter hereof.

      10.1  Binding  Effect.  This  Purchase  Option  shall inure  solely to the
benefit of and shall be binding  upon,  the  Holder  and the  Company  and their

right,  remedy or claim  under or in  respect  of or by virtue of this  Purchase
Option or any provisions herein contained.

      10.2 Governing Law; Submission to Jurisdiction. This Purchase Option shall
be governed by and  construed  and enforced in  accordance  with the laws of the
State of New York, without giving effect to conflict of laws. The Company hereby
agrees  that any  action,  proceeding  or claim  against it  arising  out of, or
relating in any way to this Purchase Option shall be brought and enforced in the
courts  of the State of New York or of the  United  States  of  America  for the
Southern  District of New York, and  irrevocably  submits to such  jurisdiction,
which jurisdiction  shall be exclusive.  The Company hereby waives any objection
to such exclusive  jurisdiction  and that such courts  represent an inconvenient
forum.  Any  process or summons to be served  upon the  Company may be served by
transmitting  a copy thereof by registered  or certified  mail,  return  receipt
requested,  postage prepaid, addressed to it at the address set forth in Section
8 hereof.  Such mailing shall be deemed personal  service and shall be legal and
binding upon the Company in any action, proceeding or claim. The Company and the
Holder agree that the prevailing party(ies) in any such action shall be entitled
to recover from the other  party(ies) all of its reasonable  attorneys' fees and
expenses  relating to such action or  proceeding  and/or  incurred in connection
with the preparation therefor.

      10.3 Waiver,  Etc. The failure of the Company or the Holder to at any time
enforce any of the  provisions  of this  Purchase  Option shall not be deemed or
construed  to be a waiver of any such  provision,  nor to in any way  affect the
validity of this  Purchase  Option or any  provision  hereof or the right of the
Company or any Holder to  thereafter  enforce  each and every  provision of this
Purchase Option. No waiver of any breach,  non-compliance or  non-fulfillment of
any of the  provisions  of this  Purchase  Option shall be effective  unless set
forth in a written  instrument  executed by the party or parties against whom or
which  enforcement  of such waiver is sought;  and no waiver of any such breach,
non-compliance or non-

                                       11
<PAGE>

fulfillment  shall  be  construed  or  deemed  to be a  waiver  of any  other or
subsequent breach, non-compliance or non-fulfillment.

      10.4 Execution in  Counterparts.  This Purchase  Option may be executed in
one or more  counterparts,  and by the  different  parties  hereto  in  separate
counterparts,  each of which shall be deemed to be an original, but all of which
taken together shall  constitute  one and the same  agreement,  and shall become
effective when one or more  counterparts  has been signed by each of the parties
hereto and delivered to each of the other parties hereto.

      10.5  Exchange  Agreement.  As a  condition  of the  Holder's  receipt and
acceptance of this Purchase Option, Holder agrees that, at any time prior to the
complete  exercise  of this  Purchase  Option by Holder,  if the Company and EBC
enter into an agreement ("Exchange Agreement") pursuant to which they agree that
all outstanding  Purchase  Options will be exchanged for securities or cash or a
combination of both, then Holder shall agree to such exchange and become a party
to the Exchange Agreement.

      10.6 Underlying Warrants. At any time after exercise by the Holder of this
Purchase  Option,  the Holder may exchange his Warrants  (with a $6.25  exercise
price) for Public  Warrants  (with a $5.00  exercise  price) upon payment to the
Company of the  difference  between  the  exercise  price of his Warrant and the
