                          SECURED CONVERTIBLE TERM NOTE
                          -----------------------------

     FOR VALUE RECEIVED, SECURED DIGITAL APPLICATIONS, INC., a Delaware

"Holder") or its registered assigns or successors in interest, on order, the sum
of Five Hundred Thousand Dollars ($500,000), together with any accrued and
unpaid interest hereon, on May 28, 2007 (the "Maturity Date") if not sooner

     Capitalized terms used herein without definition shall have the meanings
ascribed to such terms in that certain Securities Purchase Agreement dated as of
the date hereof between the Borrower and the Holder (the "Purchase Agreement").

The following terms shall apply to this Note:

                                    ARTICLE I
                             INTEREST & AMORTIZATION

     1.1(a) Interest Rate. Subject to Sections 4.11 and 5.6 hereof, interest
payable on this Note shall accrue at a rate per annum (the "Interest Rate")
equal to the "prime rate" published in The Wall Street Journal from time to
time, plus two percent (2%). The prime rate shall be increased or decreased as
the case may be for each increase or decrease in the prime rate in an amount
equal to such increase or decrease in the prime rate; each change to be
effective as of the day of the change in such rate. Subject to Section 1.1(b)
hereof, the Interest Rate shall not be less than six percent (6%). Interest
shall be (i) calculated on the basis of a 360 day year, and (ii) payable
monthly, in arrears, commencing on July 1, 2004 and on the first business day of
each consecutive calendar month thereafter until the Maturity Date (and on the
Maturity Date), whether by acceleration or otherwise (each, a "Repayment Date").

     1.1 (b) Interest Rate Adjustment. The Interest Rate shall be calculated on
the last business day of each month hereafter until the Maturity Date (each a
"Determination Date") and shall be subject to adjustment as set forth herein. If


                                       1
<PAGE>


(i) the Borrower shall have registered the shares of the Borrower's common stock
underlying each of the conversion of the Note and that certain warrant issued to
Holder on a registration statement declared effective by the Securities and
Exchange Commission (the "SEC"), and (ii) the market price (the "Market Price")
of the Common Stock as reported by Bloomberg, L.P. on the Principal Market (as
defined below) for the five (5) trading days immediately preceding a
Determination Date exceeds the then applicable Fixed Conversion Price by at
least twenty five percent (25%), the Interest Rate for the succeeding calendar
month shall automatically be reduced by 200 basis points (200 b.p.) (2.0.%) for
each incremental twenty five percent (25%) increase in the Market Price of the
Common Stock above the then applicable Fixed Conversion Price. If (i) the
Borrower shall not have registered the shares of the Borrower's common stock
underlying the conversion of the Note and that certain warrant issued to Holder
on a registration statement declared effective by the SEC and which remains
effective, and (ii) the Market Price of the Common Stock as reported by
Bloomberg, L.P. on the principal market for the five (5) trading days
immediately preceding a Determination Date exceeds the then applicable Fixed
Conversion Price by at least twenty five percent (25%), the Interest Rate for
the succeeding calendar month shall automatically be decreased by 100 basis
points (100 b.p.) (1.0.%) for each incremental twenty five percent (25%)
increase in the Market Price of the Common Stock above the then applicable Fixed
Conversion Price. Notwithstanding the foregoing (and anything to the contrary
contained in herein), if the Market Price of the Common Stock for the five (5)
trading days immediately preceding the start of any such month is below the then
Fixed Conversion Price, the Interest Rate for any such month will be reset to
the "prime rate" published in The Wall Street Journal from time to time plus two
percent (2%) and in no event shall the Interest Rate be less than zero percent
(0%).

     1.2 Minimum Monthly Principal Payments. Amortizing payments of the
aggregate principal amount outstanding under this Note at any time (the
"Principal Amount") shall begin on September 1, 2004 and shall recur on the
first business day of each succeeding month thereafter until the Maturity Date
(each, an "Amortization Date"). Subject to Article 3 below, beginning on the
first Amortization Date, the Borrower shall make monthly payments to the Holder
on each Repayment Date, each in the amount of $14,705.88, together with any
accrued and unpaid interest to date on such portion of the Principal Amount plus
any and all other amounts which are then owing under this Note, the Purchase
Agreement or any other Related Agreement but have not been paid (collectively,
the "Monthly Amount"). Any Principal Amount that remains outstanding on the
Maturity Date shall be due and payable on the Maturity Date.

                                   ARTICLE II
                              CONVERSION REPAYMENT

     2.1 (a) Payment of Monthly Amount in Cash or Common Stock. Each month by
the tenth (10th) business day prior to each Amortization Date (the "Notice
Date"), the Holder shall deliver to Borrower a written notice in the form of
Exhibit B attached hereto converting the Monthly Amount payable on the next
Repayment Date in either cash or Common Stock, or a combination of both (each, a
"Repayment Notice"). If a Repayment Notice is not delivered by the Holder on or
before the applicable Notice Date for such Repayment Date, then the Borrower
shall pay the Monthly Amount due on such Repayment Date in cash. Any portion of
the Monthly Amount paid in cash on a Repayment Date, shall be paid to the Holder



                                       2
<PAGE>

an amount equal to 101% of the principal portion of the Monthly Amount due and
owing to Holder on the Repayment Date. If the Holder converts all or a portion
of the Monthly Amount in shares of Common Stock as provided herein, the number
of such shares to be issued by the Borrower to the Holder on such Repayment Date
shall be the number determined by dividing (x) the portion of the Monthly Amount
to be paid in shares of Common Stock, by (y) the then applicable Fixed
Conversion Price. For purposes hereof, the initial "Fixed Conversion Price"
means $0.35.

     (b) Monthly Amount Conversion Guidelines. Subject to Sections 2.1(a), 2.2,
and 3.2 hereof, the Holder shall convert all or a portion of the Monthly Amount
due on each Repayment Date in shares of Common Stock if the average closing
price of the Common Stock as reported by Bloomberg, L.P. on the Principal Market
for the five (5) trading days immediately preceding such Repayment Date was
greater than or equal to 110% of the Fixed Conversion Price, provided, however,
that such conversions shall not exceed twenty five percent (25%) of the
aggregate dollar trading volume of the Common Stock for the five (5) day trading
period immediately preceding delivery of a Notice of Conversion to the Borrower.
Any part of the Monthly Amount due on a Repayment Date that the Holder has not
converted into shares of Common Stock shall be paid by the Borrower in cash on
such Repayment Date. Any part of the Monthly Amount due on such Repayment Date
which must be paid in cash (as a result of the closing price of the Common Stock
on one or more of the five (5) trading days preceding the applicable Repayment
Date being less than 110% of the Fixed Conversion Price) shall be paid in cash
at the rate of 102% of the Monthly Amount otherwise due on such Repayment Date,
within three (3) business days of the applicable Repayment Date.

     2.2 No Effective Registration. Notwithstanding anything to the contrary
herein, none of the Borrower's obligations to the Holder may be converted into
Common Stock unless (i) either (x) an effective current Registration Statement
(as defined in the Registration Rights Agreement) covering the shares of Common
Stock to be issued in connection with satisfaction of such obligations exists or
(y) an exemption from registration of the Common Stock is available to pursuant
to Rule 144 of the Securities Act and (ii) no Event of Default hereunder exists
and is continuing, unless such Event of Default is cured within any applicable
cure period or is otherwise waived in writing by the Holder in whole or in part
at the Holder's option.

     Any amounts converted by the Holder pursuant to this Section 2.2 shall be
deemed to constitute payments of outstanding fees, interest and principal
arising in connection with Monthly Amounts for the remaining Repayment Dates, in
chronological order.



     2.3 Optional Redemption in Cash. The Borrower will have the option of
prepaying this Note ("Optional Redemption") by paying to the Holder a sum of
money equal to one hundred twenty percent (120%) of the principal amount of this
Note together with accrued but unpaid interest thereon and any and all other
sums due, accrued or payable to the Holder arising under this Note, the Purchase


                                       3
<PAGE>

Agreement, or any Related Agreement (the "Redemption Amount") outstanding on the
day written notice of redemption (the "Notice of Redemption") is given to the
Holder. The Notice of Redemption shall specify the date for such Optional
Redemption (the "Redemption Payment Date") which date shall be seven (7)
business days after the date of the Notice of Redemption (the "Redemption
Period"). A Notice of Redemption shall not be effective with respect to any
portion of this Note for which the Holder has a pending election to convert
pursuant to Section 3.1, or for conversions initiated or made by the Holder
pursuant to Section 3.1 during the Redemption Period. The Redemption Amount
shall be determined as if such Holder's conversion elections had been completed
immediately prior to the date of the Notice of Redemption. On the Redemption
Payment Date, the Redemption Amount must be paid in good funds to the Holder. In
the event the Borrower fails to pay the Redemption Amount on the Redemption
Payment Date as set forth herein, then such Redemption Notice will be null and
void.



                                   ARTICLE III
                                CONVERSION RIGHTS

     3.1. Holder's Conversion Rights. The Holder shall have the right, but not
the obligation, to convert all or any portion of the then aggregate outstanding
principal amount of this Note, together with interest and fees due hereon, into
shares of Common Stock subject to the terms and conditions set forth in this
Article III. The Holder may exercise such right by delivery to the Borrower of a
written notice of conversion not less than one (1) day prior to the date upon
which such conversion shall occur.

     3.2 Conversion Limitation.

     Notwithstanding anything contained herein to the contrary, the Holder shall
not be entitled to convert pursuant to the terms of the Note an amount that
would (a) be convertible into that number of shares of Common Stock which, when
added to the number of shares of Common Stock otherwise beneficially owned by
such Holder including those issuable upon exercise of warrants held by such
Holder would exceed 4.99% of the outstanding shares of Common Stock of the
Borrower at the time of conversion or (b) exceed twenty five percent (25%) of
the aggregate dollar trading volume of the Common Stock for the five (5) day
trading period immediately preceding delivery of a Notice of Conversion to the
Borrower. For the purposes of the immediately preceding sentence, beneficial
ownership shall be determined in accordance with Section 13(d) of the Exchange
Act and Regulation 13d-3 thereunder. The conversion limitation described in this
Section 3.2 shall automatically become null and void without any notice to the
Borrower upon the occurrence and during the continuance beyond any applicable
grace period of an Event of Default, or upon 75 days prior notice to the
Borrower, except that at no time shall the beneficial ownership exceed 19.99% of
the Common Stock. Notwithstanding anything contained herein to the contrary,
following the listing of the Company on the NASDAQ SmallCap Market or the Nasdaq


                                       4
<PAGE>

National Market, the number of shares of Common Stock issuable by the Borrower
and acquirable by the Holder at a price below $0.27 per share pursuant to the
terms of this Note, the Purchase Agreement or any Related Agreement, shall not
exceed an aggregate of 17,976,786 shares of the Borrower's Common Stock (subject
to appropriate adjustment for stock splits, stock dividends, or other similar
recapitalizations affecting the Common Stock) (the "Maximum Common Stock
Issuance"), unless the issuance of shares hereunder in excess of the Maximum
Common Stock Issuance shall first be approved by the Borrower's shareholders. If
at any point in time and from time to time, following the listing of the Company
on the NASDAQ SmallCap Market or the Nasdaq National Market, the number of
shares of Common Stock issued pursuant to the terms of this Note, the Purchase
Agreement or any Related Agreement, together with the number of shares of Common
Stock that would then be issuable by the Borrower to the Holder in the event of
a conversion or exercise pursuant to the terms of this Note, the Purchase
Agreement or any Related Agreement, would exceed the Maximum Common Stock
Issuance but for this Section 3.2, the Borrower shall promptly call a
shareholders meeting to solicit shareholder approval for the issuance of the
shares of Common Stock hereunder in excess of the Maximum Common Stock Issuance.


     3.3 Mechanics of Holder's Conversion. (a) In the event that the Holder
elects to convert this Note into Common Stock, the Holder shall give notice of
such election by delivering an executed and completed notice of conversion
("Notice of Conversion") to the Borrower and such Notice of Conversion shall
provide a breakdown in reasonable detail of the Principal Amount, accrued
interest and fees being converted. On each Conversion Date (as hereinafter
defined) and in accordance with its Notice of Conversion, the Holder shall make
the appropriate reduction to the Principal Amount, accrued interest and fees as
entered in its records and shall provide written notice thereof to the Borrower
within two (2) business days after the Conversion Date. Each date on which a
Notice of Conversion is delivered or telecopied to the Borrower in accordance
with the provisions hereof shall be deemed a Conversion Date (the "Conversion
Date"). A form of Notice of Conversion to be employed by the Holder is annexed
hereto as Exhibit A.

     (b) Pursuant to the terms of the Notice of Conversion, the Borrower will
issue instructions to the transfer agent accompanied by an opinion of counsel
within one (1) business day of the date of the delivery to Borrower of the
Notice of Conversion and shall cause the transfer agent to transmit the
certificates representing the Conversion Shares to the Holder by crediting the
account of the Holder's designated broker with the Depository Trust Corporation
("DTC") through its Deposit Withdrawal Agent Commission ("DWAC") system within
three (3) business days after receipt by the Borrower of the Notice of
Conversion (the "Delivery Date"). In the case of the exercise of the conversion
rights set forth herein the conversion privilege shall be deemed to have been
exercised and the Conversion Shares issuable upon such conversion shall be
deemed to have been issued upon the date of receipt by the Borrower of the
Notice of Conversion. The Holder shall be treated for all purposes as the record
holder of such Common Stock, unless the Holder provides the Borrower written
instructions to the contrary.


                                       5
<PAGE>

         3.4      Conversion Mechanics.

     (a) The number of shares of Common Stock to be issued upon each conversion
of this Note shall be determined by dividing that portion of the principal and
interest and fees to be converted, if any, by the then applicable Fixed
Conversion Price. In the event of any conversions of outstanding principal
amount under this Note in part pursuant to this Article III, such conversions
shall be deemed to constitute conversions of outstanding principal amount
applying to Monthly Amounts for the remaining Repayment Dates in chronological
order.

     (b) The Fixed Conversion Price and number and kind of shares or other
securities to be issued upon conversion is subject to adjustment from time to
time upon the occurrence of certain events, as follows:

     A. Stock Splits, Combinations and Dividends. If the shares of Common Stock
are subdivided or combined into a greater or smaller number of shares of Common
Stock, or if a dividend is paid on the Common Stock in shares of Common Stock,
the Fixed Conversion Price or the Conversion Price, as the case may be, shall be
proportionately reduced in case of subdivision of shares or stock dividend or
proportionately increased in the case of combination of shares, in each such
case by the ratio which the total number of shares of Common Stock outstanding
immediately after such event bears to the total number of shares of Common Stock
outstanding immediately prior to such event.

     B. At all times on and after August 28, 2004, the Borrower will reserve
from its authorized and unissued Common Stock a sufficient number of shares to
provide for the issuance of Common Stock upon the full conversion of this Note.
The Borrower represents that upon issuance, such shares will be duly and validly
issued, fully paid and non-assessable. The Borrower agrees that its issuance of
this Note shall constitute full authority to its officers, agents, and transfer
agents who are charged with the duty of executing and issuing stock certificates
to execute and issue the necessary certificates for shares of Common Stock upon
the conversion of this Note.

     C. Share Issuances. Subject to the provisions of this Section 3.4, if the
Borrower shall at any time prior to the conversion or repayment in full of the
Principal Amount issue any shares of Common Stock or securities convertible into
Common Stock to a person other than the Holder (except (i) pursuant to
Subsections A or B above; (ii) pursuant to options, warrants, or other
obligations to issue shares outstanding on the date hereof as disclosed to
Holder in writing; or (iii) pursuant to options that may be issued under any
employee incentive stock option and/or any qualified stock option plan adopted
by the Borrower) for a consideration per share (the "Offer Price") less than the
Fixed Conversion Price in effect at the time of such issuance, then the Fixed
Conversion Price shall be immediately reset to such lower Offer Price at the
time of issuance of such securities. For purposes hereof, the issuance of any
security of the Borrower convertible into or exercisable or exchangeable for
Common Stock shall result in an adjustment to the Fixed Conversion Price at the
time of issuance of such securities.


                                       6
<PAGE>


     D. Reclassification, etc. If the Borrower at any time shall, by
reclassification or otherwise, change the Common Stock into the same or a
different number of securities of any class or classes, this Note, as to the
unpaid Principal Amount and accrued interest thereon, shall thereafter be deemed
to evidence the right to purchase an adjusted number of such securities and kind
of securities as would have been issuable as the result of such change with
respect to the Common Stock immediately prior to such reclassification or other
change.

     3.5 Issuance of New Note. Upon any partial conversion of this Note, a new
Note containing the same date and provisions of this Note shall, at the request
of the Holder, be issued by the Borrower to the Holder for the principal balance
of this Note and interest which shall not have been converted or paid. The
Borrower will pay no costs, fees or any other consideration to the Holder for
the production and issuance of a new Note.

                                   ARTICLE IV
                                EVENTS OF DEFAULT

     Upon the occurrence and continuance of an Event of Default beyond any
applicable grace period, the Holder may make all sums of principal, interest and
other fees then remaining unpaid hereon and all other amounts payable hereunder
immediately due and payable. In the event of such an acceleration, within five
(5) days after written notice from Holder to Borrower (each occurrence being a
"Default Notice Period") the amount due and owing to the Holder shall be 120% of
the outstanding principal amount of the Note (plus accrued and unpaid interest
and fees, if any) (the "Default Payment"). If, with respect to any Event of
Default, the Borrower cures the Event of Default, the Event of Default will be
deemed to no longer exist and any rights and remedies of Holder pertaining to
such Event of Default will be of no further force or effect. The Default Payment
shall be applied first to any fees due and payable to Holder pursuant to the
Note or the Related Agreements, then to accrued and unpaid interest due on the
Note and then to outstanding principal balance of the Note.

     The occurrence of any of the following events set forth in Sections 4.1
through 4.10, inclusive, is an "Event of Default":

     4.1 Failure to Pay Principal, Interest or other Fees. The Borrower fails to
pay when due any installment of principal, interest or other fees hereon in
accordance herewith, or the Borrower fails to pay when due any amount due under
any other promissory note issued by Borrower, and in any such case, such failure
shall continue for a period of three (3) days following the date upon which any
such payment was due.

     4.2 Breach of Covenant. The Borrower breaches any covenant or any other
term or condition of this Note or the Purchase Agreement in any material
respect, or the Borrower or any of its Subsidiaries breaches any covenant or any
other term or condition of any Related Agreement in any material respect and,
any such case, such breach, if subject to cure, continues for a period of twenty
(20) days after the occurrence thereof.

     4.3 Breach of Representations and Warranties. Any representation or
warranty made by the Borrower in this Note or the Purchase Agreement, or by the
Borrower or any of its Subsidiaries in any Related Agreement, shall, in any such
case, be false or misleading in any material respect on the date that such
representation or warranty was made or deemed made.

     4.4 Receiver or Trustee. The Borrower or any of its Subsidiaries shall make
an assignment for the benefit of creditors, or apply for or consent to the
appointment of a receiver or trustee for it or for a substantial part of its

appointed.

     4.5 Judgments. Any money judgment, writ or similar final process shall be
entered or filed against the Borrower or any of its Subsidiaries or any of their
respective property or other assets for more than $150,000, and shall remain
unvacated, unbonded or unstayed for a period of thirty (30) days.

     4.6 Bankruptcy. Bankruptcy, insolvency, reorganization or liquidation
proceedings or other proceedings or relief under any bankruptcy law or any law
for the relief of debtors shall be instituted by or against the Borrower or any
of its Subsidiaries.

     4.7 Stop Trade. An SEC stop trade order or Principal Market trading
suspension of the Common Stock shall be in effect for five (5) consecutive days
or five (5) days during a period of ten (10) consecutive days, excluding in all
cases a suspension of all trading on a Principal Market, provided that the
Borrower shall not have been able to cure such trading suspension within thirty
(30) days of the notice thereof or list the Common Stock on another Principal
Market within sixty (60) days of such notice. The "Principal Market" for the
Common Stock shall include the NASD OTC Bulletin Board, NASDAQ SmallCap Market,
NASDAQ National Market System, American Stock Exchange, or New York Stock
Exchange (whichever of the foregoing is at the time the principal trading
exchange or market for the Common Stock, or any securities exchange or other
securities market on which the Common Stock is then being listed or traded.

     4.8 Failure to Deliver Common Stock or Replacement Note. The Borrower shall
fail (i) to timely deliver Common Stock to the Holder pursuant to and in the
form required by this Note, and Section 9 of the Purchase Agreement, if such
failure to timely deliver Common Stock shall not be cured within two (2)
business days or (ii) to deliver a replacement Note to Holder within seven (7)
