      This Debenture is issued by iVOICE ACQUISITION 1, INC., a Delaware
corporation (the "Company"), to Darryl A. Moy (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 September 19,
2003, 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 One Hundred Thousand Dollars (US $10,000.00), 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. At the Company's option,
the entire principal amount and all accrued interest shall be either (a) paid to
the Holder on the second (2nd) year anniversary from the date hereof 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 $0.0001 per share ("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 National Association of Securities Dealers Inc.'s
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 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
Company shall call and hold a special meeting of its stockholders within sixty
(60) days of that time for the sole purpose of increasing the number of
authorized shares of Common Stock.

      Section 1.04 Right of Redemption. The Company at its option shall have the
right to redeem, with thirty (30) business days advance written notice (the
"Redemption Notice"), a portion of or all of the outstanding principal sum under
this Debenture. The redemption price shall be equal to one hundred twenty
percent (120%) multiplied by the portion of the principal sum being redeemed,
plus any accrued and unpaid interest. Once the Company has issued to the Holder
a Redemption Notice, the Holder may continue to convert this Debenture, in
accordance with Section 1.02 hereof, for the thirty (30) day business period
after the Holder receives the Redemption Notice, provided that the closing bid
price of the Company's Common Stock the day prior to the Conversion Date as
specified in the Conversion Notice is greater than the Closing Bid Price of the
Company's Common Stock on the Closing Date.

In the event the Company exercises its right of a redemption of either all or a
portion of the principal sum outstanding under this Debenture, as provided for
in this section, the Company shall issue to the Holder a warrant (the "Warrant")
to purchase ten thousand (10,000) shares of the Company's Common Stock for every
One Hundred Thousand Dollars ($100,000) of principal sum redeemed by the
Company, provided the Holder shall receive a pro rata portion of Warrants if the
Company redeems less than One Hundred Thousand Dollars ($100,000). The Warrant
shall be exercisable for cash consideration only and have an exercise price of
one hundred twenty percent (120%) of the closing bid price for a period of two
(2) years from the issuance of the Warrant. The Warrant shall have "piggy-back"
registration rights, shall be exercised on a "cash-basis".

      Section 1.04 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 dated January 27, 2003 (the "Investor Registration Rights
Agreement").

      Section 1.05 Guaranty. In the event of default and/or on non-performance
pursuant to the Securities Purchase Agreement, Registration Rights Agreement,
this Convertible Debenture, the Escrow Agreement, or the Transfer Agent
Agreement, this Convertible Debenture shall be immediately due and payable and
repayment shall be guaranteed pursuant to the Guaranty Agreement dated January
27, 2003.

      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
$250,000.

the Holder or to make any change that does not adversely affect the rights of
the Holder.

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.

      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 January 27, 2003 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

      Section 1.01 Principal and Interest. For value received, on September 19,
2003, 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

<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 $0.0001 per share ("Common Stock"), at the

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

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

forth in the Conversion Notice.

      Section 1.03 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

Company shall call and hold a special meeting of its stockholders within sixty
(60) days of that time for the sole purpose of increasing the number of
authorized shares of Common Stock.

      Section 1.04 Right of Redemption. The Company at its option shall have the
right to redeem, with thirty (30) business days advance written notice (the
"Redemption Notice"), a portion of or all of the outstanding principal sum under
this Debenture. The redemption price shall be equal to one hundred twenty
percent (120%) multiplied by the portion of the principal sum being redeemed,
plus any accrued and unpaid interest. Once the Company has issued to the Holder
a Redemption Notice, the Holder may continue to convert this Debenture, in
accordance with Section 1.02 hereof, for the thirty (30) day business period
after the Holder receives the Redemption Notice, provided that the closing bid
price of the Company's Common Stock the day prior to the Conversion Date as
specified in the Conversion Notice is greater than the Closing Bid Price of the
Company's Common Stock on the Closing Date.

In the event the Company exercises its right of a redemption of either all or a
portion of the principal sum outstanding under this Debenture, as provided for
in this section, the Company shall issue to the Holder a warrant (the "Warrant")
to purchase ten thousand (10,000) shares of the Company's Common Stock for every
One Hundred Thousand Dollars ($100,000) of principal sum redeemed by the
Company, provided the Holder shall receive a pro rata portion of Warrants if the

      Section 1.04 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 dated January 27, 2003 (the "Investor Registration Rights
Agreement").

      Section 1.05 Guaranty. In the event of default and/or on non-performance
pursuant to the Securities Purchase Agreement, Registration Rights Agreement,
this Convertible Debenture, the Escrow Agreement, or the Transfer Agent
Agreement, this Convertible Debenture shall be immediately due and payable and
repayment shall be guaranteed pursuant to the Guaranty Agreement dated January
27, 2003.

      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
$250,000.

the Holder.

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

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

      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 January 27, 2003 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

immediately prior to its issuance, (ii) issue or sell any warrant, option,
right, contract, call, or other security or instrument granting the holder
