                               APRIL ___, 2004


No.  ___                                                             $250,000.00

      This Secured  Debenture is issued by Cyco.Net  Inc., a Nevada  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 April ___,
2004,  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 on
April ____,  2006, the principal sum of Two Hundred Fifty  Thousand  Dollars (US
$250,000),  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  provided,
however, that in no event shall the Holder be entitled to convert this Debenture
for a number of shares  of  Common  Stock in excess of that  number of shares of
Common  Stock  which,  upon giving  effect to such  conversion,  would cause the
aggregate number of shares of Common Stock  beneficially owned by the Holder and
its  affiliates  to exceed 4.99% of the  outstanding  shares of the Common Stock
following such conversion.

<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 (the  "Conversion  Price")  equal to the lesser of (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 lowest  closing bid price of the Company's
Common Stock, as quoted by Bloomberg, LP (the "Closing Bid Price"), 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 fifteen (15)  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.

      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 fifty
thousand  (50,000)  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 of one hundred
twenty percent (120%) of the Closing Bid Price of the Company's  Common Stock on
the Closing Date. The Warrant shall have  "piggy-back"  and demand  registration
rights and shall survive for two (2) years from the Closing Date.

                                       2

      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  Holder,  in its sole
discretion,  may elect to receive  the  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 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"). As set forth in the Security Agreement, Holder's security
interest shall  terminate upon the occurrence of an Expiration  Event as defined
in the Security Agreement.

                                   ARTICLE II.

      SECTION 2.01  AMENDMENTS  AND WAIVER OF DEFAULT.  The Debenture may not be
amended without the consent of the Holder.  Notwithstanding  the above,  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 freely  tradeable  Common Stock to the Holder  within five (5) days of the

                                       3
<PAGE>

Company's receipt 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.  Upon the
occurrence  of an Event of  Default,  the Holder  may,  in its sole  discretion,
accelerate  full repayment of all debentures  outstanding  and accrued  interest
thereon or may,  notwithstanding  any  limitations  contained in this  Debenture
and/or the  Securities  Purchase  Agreement  dated the date  hereof  between the
Company  and  Cornell  Capital   Partners,   L.P.  (the   "Securities   Purchase
Agreement"),  convert all debentures  outstanding and accrued  interest  thereon
into shares of Common Stock pursuant to Section 1.02 herein.

      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 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 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  CAPITAL  STOCK OR GRANT  SECURITY
INTERESTS.  Except for the Standby Equity Distribution Agreement dated March 23,
2004 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 or Preferred Stock without consideration or for a consideration

holder a security interest in any of the assets of the Company, or (iv) file any
