                                September 2, 2003

Jersey City, New Jersey                                              $200,000.00

FOR VALUE RECEIVED, the undersigned, NEOMEDIA TECHNOLOGIES INC., a Delaware
corporation (the "Company"), promises to pay CORNELL CAPITAL PARTNERS, LP (the
"Holder") at 101 Hudson Street, Suite 3606, Jersey City, New Jersey 07302 or
other address as the Holder shall specify in writing, the principal sum of Two
Hundred Thousand (U.S.) Dollars and 00/100 ($200,000.00) and will be payable
pursuant to the following terms:

1. Amount of Note. The face amount of this Promissory Note (this "Note") shall
be payable out of the net proceeds to be received by the Company under that
certain Equity Line of Credit Agreement (the "Equity Line of Credit Agreement")
dated as November 12, 2002 between the Company and the Holder, provided that all
amounts due under this Note shall be paid in full within fifty eight (58)
calendar days of the date hereof, unless an extension is mutually agreed to by
the parties in writing. The Company agrees to escrow three (3) requests for
advances under the Equity Line of Credit Agreement, two (2) in an amount not
less than Fifty Thousand Dollars ($50,000) and one (1) in an amount not less
than One Hundred Thousand Dollars ($100,000) (individually referred to as
"Advance Notice" collectively referred to "Advance Notices") as well as an
amount of shares of the Company's Common Stock as required under Section 2.2(c)
of the Equity Line of Credit Agreement (the "Escrowed Shares"). The Escrowed
Shares are only an estimation of the shares of the Company's common stock
necessary to repay the principal amount and interest due hereunder. In the event
that during the life of this Note the Escrowed Shares are insufficient to repay
all amounts due hereunder the Company shall immediately escrow, pursuant to the
irrevocable transfer agent instructions dated the date hereof (the "Irrevocable
Transfer Agent Instructions") such number of shares of the Company's common
stock sufficient to repay all amounts due hereunder. The Advance Notices and the
shares of the Company's Common Stock will be held in escrow by the law firm of
Butler Gonzalez LLP, which shall release such requests to the Holder every seven
(7) calendar days commencing on October 13, 2003. The Holder may at its sole
discretion retain and apply the net proceeds of each advance (after deducting
any fees owed to the Holder under the terms of the Equity Line of Credit) to the
outstanding balance of this Note as existing from time to time. If this Note is
not paid in full when due, the outstanding principal owed hereunder shall be due
and payable in full together with interest thereon at the rate of twenty-four
percent (24%) per annum or the highest permitted by applicable law, if lower.
During the term of this Note the Company shall have the option to repay the
amounts due hereunder in immediately available funds and withdraw any Advance
Notices yet to be effected. At the Holder's option the interest due hereunder
shall be paid when due either in Common Stock or cash.

2. Additional Financing. If at any time during the term of this Note the
principal amount together with interest is less than Two Hundred Thousand
Dollars ($200,000) the Holder may, in its sole discretion, offer to the Company
either a promissory note or an Advance pursuant to the Equity Line of Credit
Agreement in an amount that will result all amounts, including all amounts due
pursuant to this Note, owed to the Holder by the Company equal to Two Hundred
Thousand Dollars ($200,000).

3. Waiver and Consent. To the fullest extent permitted by law and except as
otherwise provided herein, the Company waives demand, presentment, protest,
notice of dishonor, suit against or joinder of any other person, and all other
requirements necessary to charge or hold the Company liable with respect to this
Note.

4. Costs, Indemnities and Expenses. In the event of default as described herein,
the Company agrees to pay all reasonable fees and costs incurred by the Holder
in collecting or securing or attempting to collect or secure this Note,
including reasonable attorneys' fees and expenses, whether or not involving
litigation, collecting upon any judgments and/or appellate or bankruptcy
proceedings. The Company agrees to pay any documentary stamp taxes, intangible
taxes or other taxes which may now or hereafter apply to this Note or any
payment made in respect of this Note, and the Company agrees to indemnify and
hold the Holder harmless from and against any liability, costs, attorneys' fees,
penalties, interest or expenses relating to any such taxes, as and when the same
may be incurred.

5. Event of Default. Upon an Event of Default (as defined below), the entire
principal balance and accrued interest outstanding under this Note, and all
other obligations of the Company under this Note, shall be immediately due and
payable without any action on the part of the Holder, and the Holder shall be
entitled to seek and institute any and all remedies available to it. No remedy
conferred under this Note upon the Holder is intended to be exclusive of any
other remedy available to the Holder, pursuant to the terms of this Note or
otherwise. No single or partial exercise by the Holder of any right, power or
remedy hereunder shall preclude any other or further exercise thereof. The
failure of the Holder to exercise any right or remedy under this Note or
otherwise, or delay in exercising such right or remedy, shall not operate as a
waiver thereof. An "Event of Default" shall be deemed to have occurred upon the
occurrence of any of the following: (i) the Company should fail for any reason
or for no reason to make payment of the outstanding principal balance plus
accrued interest pursuant to this Note within the time prescribed herein or the
Company fails to satisfy any other obligation or requirement of the Company
under this Note; or (ii) any proceedings under any bankruptcy laws of the United
States of America or under any insolvency, not disclosed to the Holder,
reorganization, receivership, readjustment of debt, dissolution, liquidation or
any similar law or statute of any jurisdiction now or hereinafter in effect
(whether in law or at equity) is filed by or against the Company or for all or
any part of its property.

6. Maximum Interest Rate. In no event shall any agreed to or actual interest
charged, reserved or taken by the Holder as consideration for this Note exceed
the limits

                                       2
<PAGE>

imposed by New Jersey law. In the event that the interest provisions of this
Note shall result at any time or for any reason in an effective rate of interest
that exceeds the maximum interest rate permitted by applicable law, then without
further agreement or notice the obligation to be fulfilled shall be
automatically reduced to such limit and all sums received by the Holder in
excess of those lawfully collectible as interest shall be applied against the
principal of this Note immediately upon the Holder's receipt thereof, with the
same force and effect as though the Company had specifically designated such
extra sums to be so applied to principal and the Holder had agreed to accept
such extra payment(s) as a premium-free prepayment or prepayments.

7. Cancellation of Note. Upon the repayment by the Company of all of its
obligations hereunder to the Holder, including, without limitation, the face
amount of this Note, plus accrued but unpaid interest, the indebtedness
evidenced hereby shall be deemed canceled and paid in full. Except as otherwise
required by law or by the provisions of this Note, payments received by the
Holder hereunder shall be applied first against expenses and indemnities, next
against interest accrued on this Note, and next in reduction of the outstanding
principal balance of this Note.

8. Severability. If any provision of this Note is, for any reason, invalid or
unenforceable, the remaining provisions of this Note will nevertheless be valid
and enforceable and will remain in full force and effect. Any provision of this
Note that is held invalid or unenforceable by a court of competent jurisdiction
will be deemed modified to the extent necessary to make it valid and enforceable
and as so modified will remain in full force and effect.

9. Amendment and Waiver. This Note may be amended, or any provision of this Note
may be waived, provided that any such amendment or waiver will be binding on a
party hereto only if such amendment or waiver is set forth in a writing executed
by the parties hereto. The waiver by any such party hereto of a breach of any
provision of this Note shall not operate or be construed as a waiver of any
other breach.

10. Successors. Except as otherwise provided herein, this Note shall bind and
inure to the benefit of and be enforceable by the parties hereto and their
permitted successors and assigns.

11. Assignment. This Note shall not be directly or indirectly assignable or
delegable by the Company. The Holder may assign this Note as long as such
assignment complies with the Securities Act of 1933, as amended.

12. No Strict Construction. The language used in this Note will be deemed to be
the language chosen by the parties hereto to express their mutual intent, and no
rule of strict construction will be applied against any party.

13. Further Assurances. Each party hereto will execute all documents and take
such other actions as the other party may reasonably request in order to
consummate the transactions provided for herein and to accomplish the purposes
of this Note.

a decree of specific

                                       4
<PAGE>

performance and/or other injunctive relief), no remedy of the Holder contained
herein shall be deemed a waiver of compliance with the provisions giving rise to
such remedy and nothing herein shall limit the Holder's right to pursue actual
damages for any failure by the Company to comply with the terms of this Note.
Every right and remedy of the Holder under any document executed in connection
with this transaction may be exercised from time to time and as often as may be
deemed expedient by the Holder. The Company acknowledges that a breach by it of
its obligations hereunder will cause irreparable harm to the Holder and that the
remedy at law for any such breach may be inadequate. The Company therefore
agrees that, in the event of any such breach or threatened breach, the Holder
shall be entitled, in addition to all other available remedies, to an injunction
restraining any breach, and specific performance without the necessity of
showing economic loss and without any bond or other security being required.

16. Governing Law; Jurisdiction. All questions concerning the construction,
validity, enforcement and interpretation of this Agreement shall be governed by
the internal laws of the State of New Jersey, without giving effect to any
choice of law or conflict of law provision or rule (whether of the State of New
Jersey or any other jurisdictions) that would cause the application of the laws
of any jurisdictions other than the State of New Jersey. Each party hereby
irrevocably submits to the exclusive jurisdiction of the state and federal
courts sitting in Essex County, New Jersey, for the adjudication of any dispute
hereunder or in connection herewith or therewith, or with any transaction
contemplated hereby or discussed herein, and hereby irrevocably waives, and
agrees not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of any such court, that such suit, action
or proceeding is brought in an inconvenient forum or that the venue of such
suit, action or proceeding is improper. Each party hereby irrevocably waives
personal service of process and consents to process being served in any such
suit, action or proceeding by mailing a copy thereof to such party at the
address for such notices to it under this Agreement and agrees that such service
shall constitute good and sufficient service of process and notice thereof.
Nothing contained herein shall be deemed to limit in any way any right to serve
process in any manner permitted by law.

17. No Inconsistent Agreements. None of the parties hereto will hereafter enter
into any agreement, which is inconsistent with the rights granted to the parties
in this Note.

18. Third Parties. Nothing herein expressed or implied is intended or shall be
construed to confer upon or give to any person or entity, other than the parties
to this Note and their respective permitted successor and assigns, any rights or
remedies under or by reason of this Note.

19. Waiver of Jury Trial. AS A MATERIAL INDUCEMENT FOR THE HOLDER TO LOAN TO THE
COMPANY THE MONIES HEREUNDER, THE COMPANY HEREBY WAIVES ANY RIGHT TO TRIAL BY
JURY IN ANY LEGAL PROCEEDING RELATED IN ANY WAY TO THIS AGREEMENT AND/OR ANY AND
ALL OF THE OTHER DOCUMENTS ASSOCIATED WITH THIS TRANSACTION.

20. Entire Agreement. This Note (including the recitals hereto) and the Equity
