                            5% Convertible Debenture

                               Due June ___, 2004


No. ___                                                                 $150,000

     This  Debenture  is issued by IVOICE,  INC.,  a Delaware  corporation  (the
"Company"),  to   ____________________________   (together  with  its  permitted
successors and assigns,  the "Holder")  pursuant to exemptions from registration
under the Securities Act of 1933, as amended.


                                   ARTICLE I.

     Section 1.01 PRINCIPAL AND INTEREST. For value received, on June ___, 2002,
the Company hereby promises to pay to the order of the Holder in lawful money of
the United States of America and in  immediately  available  funds the principal
sum of  __________________(US  $________),  together with interest on the unpaid
principal of this  Debenture at the rate of five percent (5%) per year (computed
on the basis of a 365-day  year and the actual  days  elapsed)  from the date of
this Debenture until paid.  Unless converted  earlier in accordance with Section
1.02 hereof, all amounts due hereunder shall  automatically  convert into shares
of the  Company's  Class A common  stock,  par value  $0.001 per share  ("Common
Stock"), on the second anniversary of the date hereof. Any such conversion shall
be on the terms  specified in Section 1.02  hereof,  except that the  Conversion



Price (as defined in Section 1.02) that is used shall be the one that results in
the greatest number of shares of Common Stock being issued to the Holder.

     Section 1.02 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 at the price per share (the "Conversion  Price") equal to
either (a) an amount equal to one hundred  twenty  percent (120%) of the closing
bid price of the  Common  Stock as  listed on a  Principal  Market  (as  defined
herein),  as quoted by Bloomberg  L.P.  (the "Closing Bid Price") as of the date
hereof,  or (b) an amount  equal to eighty  percent  (80%) of the average of the
four (4) lowest  Closing Bid Prices of the Common Stock for the five (5) trading
days   immediately   preceding  the   Conversion   Date  (as  defined   herein).
Subparagraphs  (a) and (b) above are  individually  referred to as a "Conversion
Price".  As used  herein,  "Principal  Market"  shall mean the  Over-the-Counter
Bulletin Board,  Nasdaq  SmallCap  Market,  or American Stock  Exchange.  If the
Common  Stock is not traded on a Principal  Market,  the Closing Bid Price shall
mean, the reported  Closing Bid Price for the Common Stock,  as furnished by the
National Association of Securities Dealers, Inc., for the applicable periods. 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 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.

     Section 1.03  RIGHT OF REDEMPTION. The Company at its option shall have the
right to  redeem,  with ten (10)  business  days  advance  written  notice  (the
"Redemption Notice"), a portion or all outstanding  convertible  debenture.  The
redemption  price  shall be one  hundred  twenty  percent  (120%) of the  amount
redeemed  plus  accrued  interest.  Once the  Company has issued to the Holder a
Redemption Notice the Holder may continue to execute conversions only as long as
the closing bid price of the Company's  Common Stock the day prior to conversion
is above the Fixed Price.

In the event the Company  exercises a redemption  of either all or a portion the
Convertible  Debenture,  the  Holder  shall  receive a warrant to  purchase  ten
thousand  (10,000)  shares of the  Company's  Common Stock for every One Hundred
Thousand Dollars  ($100,000)  redeemed,  pro rata (the  "Warrant").  The Warrant
shall be  exercisable  on a "cash basis" and have an exercise price equal to one
hundred  twenty  percent  (120%) of the Closing Bid Price of the Common Stock as
listed on a Principal Market as of the date hereof, per share. The Warrant shall
have "piggy-back" and demand  registration  rights and shall survive for two (2)
years from the Closing Date.

     Section 1.04  RESERVATION OF COMMON  STOCK.   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,  such number of
shares of Common Stock as shall from time to time be  sufficient  to effect such
conversion, 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

                                       2


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  REGISTRATION RIGHTS. The Company is obligated to register the
resale of the  Conversion  Shares under the  Securities Act of 1933, as amended,
pursuant to the terms of a Registration  Rights  Agreement,  between the Company
and  the  Holder  of even  date  herewith  (the  "Investor  Registration  Rights
Agreement").

     Section 1.06 INTEREST PAYMENTS. The interest so payable will be paid at the
time of maturity or  conversion  to the person in whose name this  Debenture  is
registered.  At the time such  interest is  payable,  the  Company,  in its sole
discretion,  may elect to pay  interest in cash (via wire  transfer or certified
funds) or in the form of Common Stock. In the event of default,  as described in
Article III 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.

     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  SUBORDINATED  NATURE OF  DEBENTURE.  This  Debenture  and all
payments  hereon,  including  principal or interest,  shall be  subordinate  and
junior in right of payment to all  accounts  payable of the Company  incurred in
the  ordinary  course of business  and/or bank debt of the Company not to exceed
$400,000.

                                  ARTICLE II.

     Section 2.01 AMENDMENTS AND WAIVER OF DEFAULT. The Debenture may be amended
with the consent of the Holder. Without the consent of the Holder, the Debenture
may be amended to cure any ambiguity,  defect or  inconsistency,  to provide for
assumption of the Company  obligations  to the Holder or to make any change that
does not adversely affect the rights of the Holder.

                                  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 within fifteen (15) days
of the date of maturity of this Debenture;  (b) failure by the Company to comply
with the terms of the Irrevocable  Transfer Agent  Instructions  attached to the
Securities  Purchase  Agreement;  (c) failure by the Company's transfer agent to
issue Common Stock to the Holder within ten (10) days of the  Company's  receipt

                                       3


of the attached Notice of Conversion from Holder; (d) failure by the Company for
ten (10) days after notice to it to comply with any of its other  agreements  in
the  Debenture;  (e) events of  bankruptcy  or  insolvency;  (f) a breach by the
Company  of its  obligations  under the  Securities  Purchase  Agreement  or the
Investor  Registration Rights Agreement which is not cured by the Company within
ten (10) days after receipt of written notice thereof.

     Section 3.02  FAILURE TO ISSUE UNRESTRICTED  COMMON STOCK.  As indicated in
Article III 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  accelerated
full  repayment of all debentures  outstanding.  The Company  acknowledges  that
failure to honor a Notice of  Conversion  shall  cause  irreparable  harm to the
Holder.

                                  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 date of closing, 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.

     Section 4.03  TERMINATION  OF  CONVERSION  RIGHTS.  The  Holder's  right to
convert the Debenture  into the Common Stock in accordance  with  paragraph 4.01
shall terminate on the date that is the second (2nd) year  anniversary  from the
date hereof and this Debenture shall be automatically  converted on that date in
accordance  with  the  formula  set  forth  in  Section  4.01  hereof,  and  the
appropriate shares of Common Stock and amount of interest shall be issued to the
Holder.

                                   ARTICLE V.

     Section 5.01 ANTI-DILUTION. In the event that the Company shall at any time
subdivide  the  outstanding  shares  of  Common  Stock,  or shall  issue a stock
dividend  on the  outstanding  Common  Stock,  the  Conversion  Price in  effect
immediately  prior to such subdivision or the issuance of such dividend shall be
proportionately  decreased,  and in the event that the Company shall at any time
combine the outstanding  shares of Common Stock,  the Conversion Price in effect
immediately  prior  to such  combination  shall  be  proportionately  increased,
effective at the close of business on the date of such subdivision,  dividend or
combination as the case may be.

     Section 5.02 CONSENT OF HOLDER TO SELL COMMON STOCK.  Except for the Equity
Line of Credit  Agreement  dated the date hereof between the Company and Cornell
Capital  Partners,  LP. so long as any of the  principal  of or interest on this
Note remains unpaid and  unconverted,  the Company shall not,  without the prior
consent of the Holder, issue or sell (i) any Common Stock without  consideration
or for a  consideration  per share less than its fair  market  value  determined
immediately  prior to its  issuance,  (ii)  issue or sell any  warrant,  option,
right,  contract,  call,  or other  security or  instrument  granting the holder
thereof  the  right to  acquire  Common  Stock  without  consideration  or for a
consideration  per  share  less than  such  Common  Stock's  fair  market  value

determined  immediately  prior to its issuance,  or (iii) file any  registration
