                                SECURED DEBENTURE

                              OXFORD VENTURES, INC.

                        10% SECURED CONVERTIBLE DEBENTURE

                              DUE OCTOBER __, 2007

No. Prenox-001                                                     US$10,000,000

      This Secured  Debenture  (the  "Debenture")  is issued on October __, 2005
(the  "Closing  Date") by  Oxford  Ventures,  Inc.,  a Nevada  corporation  (the
"Company"),  to Prenox, LLC (together with its permitted successors and assigns,
the "Holder")  pursuant to exemptions from registration under the Securities Act
of 1933, as amended, pursuant to a Securities Purchase Agreement,  dated October
__, 2005 (the "Securities  Purchase  Agreement")  among the Company and Buyer(s)
listed on Schedule I thereto.

                                   ARTICLE I.

      SECTION 1.01  PRINCIPAL  AND  INTEREST.  For value  received,  the Company
hereby  promises to pay to the order of the Holder on the date  October __, 2007
("Maturity  Date"),  in lawful  money of the  United  States of  America  and in
immediately   available   funds  the  principal  sum  of  Ten  Million   Dollars
($10,000,000),  together with interest on the unpaid principal of this Debenture
at the rate of ten percent (10%) per year (compounded  monthly) from the date of
this Debenture  until paid. The Company will begin making monthly  interest only
payments on the Note of accrued  interest  every thirty (30) days  following the
Closing  Date.  At the  Holder's  option,  the entire  principal  amount and all
accrued and unpaid interest and the Redemption Premium specified in Section 1.05
hereof  shall be  either  (a) paid to the  Holder  on the  Maturity  Date or (b)
converted in accordance with Section 1.02 herein.

<PAGE>

      SECTION 1.02 OPTIONAL CONVERSION.  The Holder is entitled,  at its option,
to convert,  and sell on the same day, at any time and from time to time,  until
payment in full of this  Debenture,  all or any part of the principal  amount of
the Debenture,  plus accrued interest,  into shares (the "Conversion Shares") of
the Company's common stock, par value $0.001 per share ("Common Stock"),  at the
price per share equal to $1.50 (the "Conversion  Price").  No fraction of shares
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.  To
convert this Debenture,  the Holder hereof shall deliver written notice thereof,
substantially  in the form of  Exhibit  A to this  Debenture,  with  appropriate
insertions  (the  "Conversion  Notice"),  to the Escrow Agent (as defined in the
Securities  Purchase  Agreement)  and the  Company  at its  address as set forth
herein.  The date upon which the conversion  shall be effective (the "Conversion
Date") shall be deemed to be the date set forth in the  Conversion  Notice.  The
Holder has the right to convert this Debenture  after the Maturity Date.  Absent
manifest  error;  the Escrow Agent shall release the shares of Common Stock from
escrow on the third (3rd) business day following the Escrow Agent  notifying the
Company of the  conversion.  Any  conversion  of any portion of the Debenture to
Common Stock shall be deemed to be a pre-payment  of principal  plus accrued and
unpaid interest,  without any penalty,  and shall be credited against any future
payments of principal  and interest in the order that such  payments  become due
and payable.

      Section 1.03. MONTHLY PAYMENTS. The interest so payable will be paid every
thirty (30) days  following the Closing Date.  This  Debenture  ranks pari passu
with all other  Debentures now or hereinafter  issued pursuant to the Securities
Purchase  Agreement.  In the event of  default,  as  described  in Section  3.01
hereunder,  the  Holder may elect  that the  interest  be paid in cash (via wire
transfer or certified funds) or in the form of Common Stock. If paid in the form
of 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:  (i) the date the
interest  payment is due; or (ii) if the interest  payment is not made when due,
the date the interest payment is made. A number of shares of Common Stock with a
value equal to the amount of interest due shall be issued.  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 will pay the balance in
cash.

      The Company shall make monthly scheduled payments  ("Scheduled  Payments")
consisting of principal and accrued interest.  The first Scheduled Payment shall
be due and  payable on the date one hundred  eighty  (180) days from the Closing
Date. After the first Scheduled Payment, each subsequent Scheduled Payment shall
be due and payable on the same day of each  subsequent  calendar month until the
Maturity  Date.  The  principal  amount  of  each  Scheduled  Payment  shall  be
determined by dividing the outstanding  principal amount of this Debenture as of
the date of such Scheduled Payment by the number of Scheduled Payments remaining
until the  Maturity  Date plus a repayment  premium  equal to five  percent (5%)
("Repayment  Premium") of the amount of the principal  payment.  All payments in
respect of the  indebtedness  evidenced hereby shall be made in collected funds,
and shall be applied to  principal,  accrued  interest  and charges and expenses
owing under or in  connection  with this  Debenture  in such order as the Holder
elects,  except  that  payments  shall be  applied to  accrued  interest  before
principal.

                                       2
<PAGE>

      In the event that the Company redeems a portion of the amount  outstanding
under this Debenture,  or the Holder converts a portion of the principal  amount
outstanding and accrued  interest under this Debenture as  contemplated  herein,
the  Company  shall be  entitled  to an off-set of the amount of  principal  and
accrued  interest due pursuant to the  Schedule  Payment  equal to the amount of
principal and accrued interest redeemed or converted (the "Off-Set Amount").  In
such event the Company  shall  still be  obligated  to make a Scheduled  Payment
reduced by the Off-Set Amount as contemplated hereunder.

      During any time that this  Debenture  is held by an  affiliate of Highgate
House  Funds,  Ltd.  (as  defined  in Rule 144  promulgated  under  the Act,  as
amended),  the Company may not redeem this  Debenture  with the  proceeds of the
Standby Equity  Distribution  Agreement  between the Company and Cornell Capital
Partners, LP.

      Section 1.04  RESERVATION OF COMMON STOCK. As set forth in Section 6(c) of
the Securities Purchase Agreement,  the Company shall reserve and keep available
out of its  authorized  but  unissued  shares of Common  Stock,  solely  for the
purpose of effecting the conversion of this Debenture,  that number of shares of
Common  Stock  equal to a  multiple  of five (5) times  the  number of shares of
Common  Stock into which the  Debenture is  convertible  from time to time based
upon the Conversion Price. If at any time the Company does not have a sufficient
number of Conversion  Shares  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.

      Section 1.05 RIGHT OF REDEMPTION. The Company at its option shall have the
right to redeem,  with three (3)  business  days  advance  written  notice  (the
"Redemption Notice"), a portion or all of the outstanding Convertible Debenture.
The redemption price shall be One Hundred Twenty percent (120%) (the "Redemption
Price") of the face amount redeemed plus accrued interest. The Company shall pay
the  Redemption  Price on all payments made prior to a Scheduled  Payment or any
other payment due date.  For all payments under this  Debenture,  the payment of
the Redemption Price by the Company shall be in addition to any accrued interest
due.

      Section 1.06 REGISTRATION RIGHTS. The Company is obligated to register the
resale  of the  Conversion  Shares  under  the Act,  pursuant  to the terms of a
Investor  Registration  Rights  Agreement,  between the Company and the Buyer(s)
listed on Schedule I thereto of even date herewith (the  "Investor  Registration
Rights Agreement").

      Section 1.07 PAYING AGENT AND REGISTRAR.  Initially,  the Company will act
as paying  agent and  registrar.  The  Company  may  change  any  paying  agent,
registrar,  or  Company-registrar  by giving  the  Holder not less than ten (10)
business  days' written  notice of its election to do so,  specifying  the name,
address, telephone number and facsimile number of the paying agent or registrar.
The Company may act in any such capacity.

      Section 1.08 SECURED NATURE OF DEBENTURE. This Debenture is secured by all
of the  assets  and  property  of the  Company  as set forth on Exhibit A to the
Security Agreement dated the date hereof between the Company and the Holder (the
"Security Agreement").

                                       3
<PAGE>

      Section  1.09 THE ESCROW  SHARES.  The Company  shall  deposit  50,000,000
shares of Common Stock with the Escrow Agent as "Escrow Shares." Upon receipt of
the  Conversion  Notice from the Holder,  the Escrow Agent shall  distribute the
Conversion  Shares to  Holder  pursuant  to this  Debenture  and the  Securities
Purchase Agreement including Exhibit F thereto.

                                  ARTICLE II.

      SECTION 2.01  AMENDMENTS  AND WAIVER OF DEFAULT.  The Debenture may not be
amended.  Notwithstanding  the above,  without the  consent of the  Holder,  the
Debenture may be amended to cure any ambiguity, defect or inconsistency.

                                  ARTICLE III.

      SECTION 3.01 EVENTS OF DEFAULT. An Event of Default is defined as follows:
(a) failure by the Company to pay amounts due hereunder on the Maturity  Date, a
Scheduled  Payment date or  otherwise  after the  expiration  of a seven (7) day
period to cure such failure;  (b) failure by the Company's transfer agent (aside
for reason of error) to issue freely tradeable Common Stock to the Holder within
twelve (12) days of the Company's receipt of the attached Conversion Notice from
Holder;  (c)  failure by the  Company  for ten (10) days  after  notice to it to
comply with any of its other agreements in the Debenture;  (d) failure to comply
with the terms of the Irrevocable Transfer Agent Instructions (as defined in the
Securities  Purchase  Agreement);  (e) if the Company files for relief under the
United States  Bankruptcy Code (the "Bankruptcy  Code") or under any other state
or federal  bankruptcy or insolvency law, or files an assignment for the benefit
of creditors, or if an involuntary proceeding under the Bankruptcy Code or under
any other federal or state bankruptcy or insolvency law is commenced against the
Company;  or (f) a breach by the  Company  of its  obligations  under any of the
Transaction Documents (as defined in the Securities Purchase Agreement) which is
not cured by the Company  within any  allocated  cure period  therein.  Upon the
occurrence of an Event of Default,  the Holder may, in its sole discretion,  (i)
accelerate  full repayment of all debentures  outstanding  and accrued  interest
thereon at the Redemption  Price and/or (ii) convert all debentures  outstanding
and accrued  interest  thereon at twenty  percent  (20%) of the then  Conversion
Price.  The failure of the Company to make Payments due under Section 1.03 shall
also be deemed as an Event of  Default.  Upon an Event of  Default,  the  Escrow
Agent is  authorized  and directed to release the Escrow  Shares to the Buyer if
requested by the Buyer, without approval of the Company.

      SECTION 3.02 FAILURE TO ISSUE  UNRESTRICTED  COMMON STOCK. As indicated in
Section  3.01,  a breach by the Company of its  obligations  under the  Investor
Registration Rights Agreement shall be deemed an Event of Default,  which if not
cured  within  ten (10)  days,  shall  entitle  the  Holder to  accelerate  full
repayment  of all  debentures  outstanding  and  accrued  interest  thereon  or,
notwithstanding   any  limitations   contained  in  this  Debenture  and/or  the
Securities Purchase Agreement, to convert all debentures outstanding and accrued
interest  thereon into shares of Common  Stock  pursuant to Section 1.02 herein.
The Company  acknowledges  that failure to honor a Conversion Notice shall cause
irreparable harm to the Holder.

                                       4

                                  ARTICLE IV.

      SECTION 4.01 RIGHTS AND TERMS OF CONVERSION.  This Debenture,  in whole or
in part,  may be converted at any time following the Closing Date (as defined in
the Securities Purchase Agreement), into shares of Common Stock at a price equal
to the Conversion Price as described in Section 1.02 above.

      SECTION 4.02 RE-ISSUANCE OF DEBENTURE. When the Holder elects to convert a
part of the  Debenture,  then the Company  shall  reissue a new Debenture in the
same form as this Debenture to reflect the new principal amount.

                                   ARTICLE V.

      SECTION 5.01 ANTI-DILUTION. Adjustment of Conversion Price. The Conversion
Price shall be adjusted from time to time as follows:

            (a)   Adjustment  of  Conversion  Price and  Number  of Shares  upon
Issuance of Common  Stock.  If and whenever on or after the Closing Date of this
Debenture, the Company issues or sells, or is deemed to have issued or sold, any
shares of Common Stock (other than (i) Excluded  Securities (as defined herein),
(ii)  shares of Common  Stock  which are issued or deemed to have been issued by
the Company in connection with an Approved Stock Plan (as defined  herein),  and
(iii) upon the issuance,  exercise or conversion of Other Securities (as defined
herein))  for a  consideration  per  share  less than a price  (the  "Applicable
Price") equal to $1.25 or if the Conversion  Price has previously  been adjusted
pursuant to Section 5.01 hereof, then the Conversion Price in effect immediately
prior to such issuance or sale,  then  immediately  after such issue or sale the
Conversion  Price shall (until  another such issuance or sale) be reduced to the
price equal to the  quotient  derived by dividing (A) an amount equal to the sum
of (X) the product of (a) the Conversion Price on the date immediately  prior to
the  issuance  or sale of such  shares,  multiplied  by (b) the total  number of
shares of Common Stock  outstanding  immediately  prior to such issuance or sale
plus, (Y) the aggregate of the amount of all consideration,  if any, received by
the Company  upon such  issuance or sale,  by (B) the total  number of shares of
Common Stock  outstanding  immediately  after such  issuance or sale;  provided,
however, that in no event shall the Conversion Price be reduced below $.001.

            (b)   Effect on Conversion Price of Certain Events.  For purposes of
determining  the adjusted  Conversion  Price under Section  5.01(a)  above,  the
following shall be applicable:

                  (i)   Issuance  of  Options.  If after  the date  hereof,  the
Company in any manner grants any rights, warrants or options to subscribe for or
purchase Common Stock or convertible securities ("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 Conversion Price then
in effect, 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
5.01(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

                                       5
<PAGE>

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 other  convertible  security
other than this  Debenture  issuable  upon  exercise of such Option.  No further
adjustment  of the  Conversion  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.  If the Company in
any manner issues or sells any convertible securities after the Closing Date 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  Conversion  Price then in
effect, 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  5.01(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 Conversion 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
Conversion Price had been or are to be made pursuant to other provisions of this
Section 5.01(b),  no further adjustment of the Conversion Price shall be made by
reason of such issue or sale.

                  (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 Conversion  Price in
effect at the time of such  change  shall be adjusted  to the  Conversion  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 shares of Common Stock issuable upon conversion
of this  Debenture  shall be  correspondingly  readjusted.  For purposes of this
Section  5.01(b)(iii),  if the terms of any Option or convertible  security that
was  outstanding  as of the Closing  Date of this  Debenture  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  5.01(b) shall be
made if such adjustment would result in an increase of the Conversion Price then
in effect.

            (c)   Effect on Conversion Price of Certain Events.  For purposes of
determining the adjusted  Conversion  Price under Sections  5.01(a) and 5.01(b),
the following shall be applicable:

                                       6
<PAGE>

                  (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 gross 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 the  Debenture  representing  at least
two-thirds  of the  shares of  Common  Stock  issuable  upon  conversion  of the
Debenture 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 the Debenture  representing at least  two-thirds of the shares of
Common Stock  issuable upon  conversion of the Debenture 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 by the  non-prevailing
party.

                  (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 $.001.

                  (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 Conversion Price upon Subdivision or Combination
of Common  Stock.  If the Company at any time after the date of issuance of this
Debenture  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 Conversion Price in effect  immediately  prior to
such subdivision  will be  proportionately  reduced.  If the Company at any time

                                       7
<PAGE>

after the date of issuance of this Debenture  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  Conversion  Price in effect
immediately  prior to such combination will be  proportionately  increased.  Any
adjustment  under this Section  5.01(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 Debenture, then, in each
such  case any  Conversion  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
Conversion  Price by a fraction of which (A) the numerator  shall be the closing
bid 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 bid price of the Common  Stock on the
trading day immediately preceding such record date; and

            (f)   Certain Events.  If any event occurs of the type  contemplated
by the  provisions of this Section 5.01 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
Conversion  Price so as to protect the rights of the  holders of the  Debenture;
provided,  except  as set  forth in  Section  5.01(d),  that no such  adjustment
pursuant to this Section 5.01(f) will increase the Conversion Price as otherwise
determined pursuant to this Section 5.01.

            (g)   Notices.

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

                  (ii)  The Company  will give  written  notice to the holder of
this  Debenture  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  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.

                        WARRANT TO PURCHASE COMMON STOCK

                                       OF

                              OXFORD VENTURES, INC.

THIS WARRANT AND THE SECURITIES INTO WHICH IT IS EXERCISABLE (COLLECTIVELY,  THE
"SECURITIES")  HAVE NOT BEEN  REGISTERED  UNDER THE  SECURITIES  ACT OF 1933, AS
AMENDED (THE "ACT"), OR THE SECURITIES LAWS OF ANY STATE. THE SECURITIES MAY NOT

      FOR VALUE RECEIVED,  Oxford Ventures,  Inc., a corporation organized under
the laws of Nevada  (the  "Company"),  grants the  following  rights to Highgate
House Funds, Ltd., a Cayman Islands company and/or its assigns (the "Holder"):

                             ARTICLE 1. DEFINITIONS

      Capitalized  terms used and not  otherwise  defined  herein shall have the
meanings  given such terms in the Securities  Purchase  Agreement by and between
the Company and the Holder and entered into on October ___, 2005 (the  "Purchase
Agreement").  As used in this  Agreement,  the  following  terms  shall have the
following meanings:

      "Corporate Office" shall mean the office of the Company (or its successor)
at which at any particular time its principal business shall be administered.

      "Exercise  Date" shall mean any date on which the Holder gives the Company
a Notice of Exercise in  compliance  with the terms of Exhibit E to the Purchase
Agreement.

      "Exercise  Price"  shall mean the Fixed  Price per share of Common  Stock,
subject to adjustment as provided herein.

      "Expiration  Date" shall mean 5:00 p.m.  (New York time) on October  ____,
2010.

      "Fair Market Value" shall have the meaning set forth in Section 2.2(b).

      "Fixed Price" shall mean US$0.01.

<PAGE>

      "Market Value" shall have the meaning set forth in Section 2.2(b).

      "SEC" shall mean the United States Securities and Exchange Commission.

      "Warrant  Shares" shall mean the shares of the Common Stock  issuable upon
exercise of this Warrant.

                       ARTICLE 2. EXERCISE AND AGREEMENTS

      2.1   Exercise of Warrant;  Sale of Warrant and Warrant  Shares.  (a) This
Warrant shall entitle the Holder to purchase,  at the Exercise Price,  1,166,667
shares of Common Stock.  This Warrant shall be  exercisable at any time and from
time to time  from  the  date  hereof  and  prior to the  Expiration  Date  (the
"Exercise  Period").  This  Warrant  and the right to  purchase  Warrant  Shares
hereunder shall expire and become void on the Expiration Date.

      2.2   Manner of Exercise.

            (a)   The Holder may exercise this Warrant at any time and from time
to  time  during  the  Exercise  Period,  in  whole  or  in  part  (but  not  in
denominations  of fewer than 10,000 Warrant  Shares,  except upon an exercise of
this Warrant with respect to the remaining balance of Warrant Shares purchasable
hereunder at the time of exercise),  by delivering to the Escrow Agent  pursuant
to the Escrow  Agreement  incorporated  herein by reference  (i) a duly executed
Notice of Exercise in substantially the form attached as Appendix I hereto, (ii)
the  certificate  representing  the  Warrants  and  (iii)  a bank  cashier's  or
certified  check for the aggregate  Exercise  Price of the Warrant  Shares being
purchased.

            (b)   The Holder may, at its option,  in lieu of paying cash for the
Warrant  Shares,  exercise  this Warrant by an exchange,  in whole or in part (a
"Warrant  Exchange"),  by  delivery to the Escrow  Agent of (i) a duly  executed
Notice  of  Exercise  electing  a  Warrant  Exchange  and (ii)  the  certificate
representing this Warrant.  In connection with any Warrant Exchange,  the Holder
shall be deemed to have paid for the Warrant  Shares an amount equal to the Fair
Market  Value of each  Warrant  delivered,  and the  Warrants  shall  be  deemed
exercised  for the amount so paid.  For this  purpose,  the Fair Market Value of
each  Warrant is the  difference  between the Market  Value of a share of Common
Stock and the Exercise Price on the Exercise  Date.  Market Value shall mean the
average Closing Bid Price of a share of Common Stock during the ten (10) Trading
Days ending on the Exercise Date.

they have not been exercised, shall terminate on the Expiration Date.

      2.4   No Rights  Prior to  Exercise.  This  Warrant  shall not entitle the
Holder to any voting or other rights as a stockholder of the Company.

                                       2
<PAGE>

      2.5   Fractional  Shares.  No  fractional  shares  shall be issuable  upon
exercise of this Warrant, and the number of Warrant Shares to be issued shall be
rounded up to the nearest whole number.  If, upon exercise of this Warrant,  the
Holder  hereof would be entitled to receive any  fractional  share,  the Company
shall issue to the Holder one  additional  share of Common Stock in lieu of such
fractional share.

      2.6   Escrow. The Company agrees to enter into the Escrow Agreement and to
deposit with the Escrow Agent  thereunder stock  certificates  registered in the
name of the Holder,  each  representing  a number of shares of Common  Stock (in
denominations  specified by the Purchaser) equal, in the aggregate, to the total
number of  Warrant  Shares  for which  this  Warrant  is  exercisable,  assuming
exercise of this Warrant in full on the date hereof.  The Company  shall deposit
additional  certificates  for Warrant  Shares upon  request by the Escrow  Agent
pursuant to the Escrow Agreement.

      2.7   Adjustments to Exercise Price and Number of Securities.

            (a)   Subdivision and Combination.  In case the Company shall at any
time subdivide or combine the outstanding  shares of Common Stock,  the Exercise
Price shall forthwith be proportionately decreased in the case of subdivision or
increased in the case of combination.

            (b)   Adjustment in Number of  Securities.  Upon each  adjustment of
the Exercise Price pursuant to the provisions of this Section 2.7, the number of
Warrant  Shares  issuable upon the exercise of each Warrant shall be adjusted to
the nearest whole number by  multiplying a number equal to the Exercise Price in
effect  immediately  prior to such  adjustment  by the number of Warrant  Shares
issuable upon exercise of the Warrants  immediately prior to such adjustment and
dividing the product so obtained by the adjusted Exercise Price.

            (c)   Merger or  Consolidation.  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  warrant  agreement  providing that the Holder of each
Warrant then  outstanding or to be outstanding  shall have the right  thereafter
(until the  expiration  of such  Warrant)  to  receive,  upon  exercise  of such
Warrant,  the kind and  amount  of shares  of stock  and  other  securities  and
property  (except in the event the property is cash,  then the Holder shall have
the right to exercise  the Warrant and receive  cash in the same manner as other
stockholders)  receivable upon such  consolidation or merger, by a holder of the
number of shares of Common  Stock of the  Company for which such  warrant  might
have been exercised  immediately prior to such  consolidation,  merger,  sale or
transfer.  Such  supplemental  warrant  agreement  shall provide for adjustments
which  shall be  identical  to the  adjustments  provided  in Section  2.7.  The
foregoing  provisions of this paragraph (e) shall  similarly apply to successive
consolidations or mergers.

            (d)   No  Adjustment  of  Exercise  Price  in  Certain   Cases.   No
adjustment of the Exercise  Price shall be made upon the issuance of the Warrant
Shares or upon the exercise of any options,  rights, or warrants  outstanding as
of the date of the Purchase Agreement and disclosed in Section 3.1(c) therein.

                                       3
<PAGE>

            (e)   Dividends  and  Other  Distributions.  In the  event  that the
Company  shall at any time  prior to the  exercise  of all  Warrants  declare  a
dividend (other than a dividend  consisting solely of shares of Common Stock) or
otherwise distribute to its stockholders any assets, property, rights, evidences
of indebtedness,  securities (other than shares of Common Stock), whether issued
by the  Company or by another,  or any other thing of value,  the Holders of the
unexercised Warrants shall thereafter be entitled,  in addition to the shares of
Common  Stock or other  securities  and  property  receivable  upon the exercise
thereof,  to receive,  upon the exercise of such  Warrants,  the same  property,
assets,  rights,  evidences of  indebtedness,  securities  or any other thing of
value that they would have been entitled to receive at the time of such dividend
or distribution as if the Warrants had been exercised  immediately prior to such
dividend or distribution. At the time of any such dividend or distribution,  the
Company shall make appropriate  reserves to ensure the timely performance of the
provisions of this subsection 2.7 (g).  Nothing  contained  herein shall provide
for the receipt or accrual by a Holder of cash  dividends  prior to the exercise
by such Holder of the Warrants.

      2.8   Registration  Rights. The Holder shall have the registration  rights
in the Investor Registration Rights Agreement.

                            ARTICLE 3. MISCELLANEOUS

      3.1   Transfer.  This  Warrant  may  not be  offered,  sold,  transferred,
pledged,  assigned,  hypothecated or otherwise disposed of, in whole or in part,
at any time,  except in compliance with applicable  federal and state securities
laws by the transferor and the transferee  (including,  without limitation,  the
delivery of an investment  representation  letter and a legal opinion reasonably
satisfactory to the Company).

      3.2   Transfer  Procedure.  Subject to the  provisions of Section 3.1, the
Holder may transfer or assign this Warrant by giving the Company  notice setting
forth the name, address and taxpayer  identification number of the transferee or
assignee, if applicable (the "Transferee"), and surrendering this Warrant to the
Company  for  reissuance  to the  Transferee  and, in the event of a transfer or
assignment of this Warrant in part, the Holder. (Each of the persons or entities
in whose name any such new Warrant  shall be issued are herein  referred to as a
"Holder").

      3.3   Loss, Theft, Destruction or Mutilation. If this Warrant shall become
mutilated or defaced or be destroyed,  lost or stolen, the Company shall execute
and deliver a new Warrant in exchange for and upon surrender and cancellation of
such mutilated or defaced  Warrant or, in lieu of and in  substitution  for such
Warrant so destroyed, lost or stolen, upon the Holder filing with the Company an
affidavit that such Warrant has been so mutilated,  defaced,  destroyed, lost or
stolen.  However, the Company shall be entitled, as a condition to the execution
and delivery of such new Warrant, to demand reasonably  acceptable  indemnity to
it and payment of the  expenses  and charges  incurred  in  connection  with the
delivery of such new Warrant. Any Warrant so surrendered to the Company shall be
canceled.

as the case may be, in writing by the Company or the Holder from time to time.

      3.5   Waiver. This Warrant and any term hereof may be changed,  waived, or
terminated  only by an instrument  in writing  signed by the party against which
enforcement of such change, waiver, discharge or termination is sought.

      3.6   Governing  Law.  This Warrant  shall be governed by and construed in
accordance with the laws of the State of New York,  without giving effect to its
principles  regarding  conflicts of law. Any action to enforce the terms of this
Warrant shall be  exclusively  heard in the county,  state and federal Courts of
New York and Country of the United States of America.

      3.7   Signature.  In the  event  that any  signature  on this  Warrant  is
delivered by facsimile  transmission,  such  signature  shall create a valid and
binding  obligation of the party executing (or on whose behalf such signature is
executed)  the  same,  with the  same  force  and  effect  as if such  facsimile
signature page were an original thereof.

      3.8   Legal  Fees.  In the event any Person  commences  a legal  action or
proceeding to enforce its rights under this Warrant, the non-prevailing party to
such action or  proceeding  shall pay all  reasonable  and  necessary  costs and
expenses  (including  reasonable  and  necessary  attorney's  fees)  incurred in
enforcing such rights.
