                           WARRANT TO PURCHASE SHARES
                                 OF COMMON STOCK
                                       OF
                           NEOMEDIA TECHNOLOGIES, INC.

                       Warrant to Purchase 135,000 Shares
                   (subject to adjustment as set forth herein)

                         Exercise Price $7.50 Per Share
                   (subject to adjustment as set forth herein)

             VOID AFTER 11:59 P.M., EASTERN TIME, DECEMBER 11, 2002

THE SECURITIES REPRESENTED BY THIS WARRANT HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933 (the "Act") OR REGISTERED OR QUALIFIED UNDER ANY OTHER
APPLICABLE FEDERAL OR STATE SECURITIES LAWS. THESE SECURITIES MAY NOT BE OFFERED
FOR SALE, SOLD, OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE
REGISTRATION STATEMENT OR QUALIFICATION FILED IN ACCORDANCE WITH THE ACT OR
PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE ACT.

      NeoMedia Technologies, Inc. (the "Company") hereby certifies that, for
value received, Thornhill Capital, L.L.C., 1616 Thornhill Drive, Springfield,
Illinois, 62707 (the "Holder"), is entitled, subject to the terms and conditions
set forth below, to purchase from the Company at any time at or before 11:59
p.m., Eastern time, on December 11, 2002, up to 135,000 Shares ("Share" in the
singular and "Shares" in the plural) of the Company's $.01 par value common
stock ("Common Stock") at a purchase price of $7.50 per Share (the "Exercise
Price"). Neither this Warrant nor the Shares issuable upon exercise of this
Warrant have been registered under the Act nor have they been registered or
qualified under any other applicable federal or state securities laws.
Accordingly, neither this Warrant nor the Shares issuable upon exercise of this
Warrant may be offered for sale, sold or otherwise transferred except pursuant
to an effective registration statement or qualification filed in accordance with
the Act and applicable state securities laws or pursuant to an exemption from
registration under the Act and applicable state securities laws.

      The number of the securities purchasable upon exercise of this Warrant and
the Exercise Price are subject to adjustment as provided below. The term
"Warrant" as used herein shall include this Warrant and any warrants issued in
substitution for or replacement of this Warrant, or any warrants into which this
Warrant may be divided or exchanged. The Shares purchasable upon the exercise of
this Warrant are hereinafter referred to as "Warrant Securities."

      This Warrant may be assigned, transferred, sold or offered for sale by the
Holder upon compliance with all the pertinent provisions hereof.

      1.   EXERCISE OF WARRANT.

      (a) Subject to the other terms and conditions of this Warrant, the
purchase rights evidenced by this Warrant may be exercised in whole or in part
at any time, and from time to time, prior to 11:59 p.m., Eastern time, on
December 11, 2002, by the Holder's presentation and surrender of this Warrant to
the Company at its principal office accompanied by a duly executed Notice of
Exercise, in the form attached to and by this reference incorporated in this
Warrant as Exhibit A, and by payment of the aggregate Exercise Price, in
certified funds or a bank cashier's check.

                                       93

<PAGE>

This Warrant may only be exercised for the purchase of whole Shares. In
the event this Warrant is exercised in part only, as soon as is practicable
after the presentation and surrender of this Warrant to the Company for
exercise, the Company shall execute and deliver to the Holder a new Warrant,
containing the same terms and conditions as this Warrant, evidencing the right
of the Holder to purchase the number of Shares as to which this Warrant has not
been exercised.

      (b) Upon receipt of this Warrant by the Company as described in subsection
(a) above, the Holder shall be deemed to be the holder of record of the Warrant
Securities issuable upon such exercise, notwithstanding that the transfer books
of the Company may then be closed or that certificates representing such Warrant
Securities may not have been prepared or actually delivered to the Holder.

      2.   EXCHANGE, ASSIGNMENT OR LOSS OF WARRANT.

      (a) This Warrant may be sold, transferred, assigned, pledged or
hypothecated immediately in accordance with the provisions hereof. In addition,
all sales, transfers, assignments or hypothecations of this Warrant must be in
compliance with Section 6 hereof. Any assignment or transfer of this Warrant
shall be made by the presentation and surrender of this Warrant to the Company
at its principal office accompanied by a duly executed Assignment Form, in the
form attached to and by this reference incorporated in this Warrant as Exhibit
B. Upon the presentation and surrender of these items to the Company, the
Company shall execute and deliver to the new Holder or Holders a new Warrant or
Warrants, containing the same terms and conditions as this Warrant, in the name
of the new Holder or Holders as named in the Assignment Form, and this Warrant
shall at that time be canceled.

      (b) This Warrant, alone or with other Warrants containing substantially
the same terms and conditions and owned by the same Holder, is exchangeable at
the option of the Holder at any time prior to its expiration either by its terms
or by its exercise in full upon presentation and surrender to the Company at its
principal office for another Warrant or other Warrants, of different
denominations but containing the same terms and conditions as this Warrant,
entitling the Holder to purchase the same aggregate number of Warrant Securities
that were purchasable pursuant to the Warrant or Warrants presented and
surrendered. At the time of presentation and surrender by the Holder to the
Company, the Holder also shall deliver to the Company a written notice, signed
by the Holder, specifying the denominations in which new Warrants are to be
issued to the Holder.

      (c) The Company will execute and deliver to the Holder a new Warrant
containing the same terms and conditions as this Warrant upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft,
destruction, or mutilation of this Warrant, provided that (i) in the case of
loss, theft, or destruction, the Company receives from the Holder an
indemnification satisfactory to it, and (ii) in the case of mutilation, the
Holder presents and surrenders this Warrant to the Company for cancellation. Any
new Warrant executed and delivered shall

                                       94

<PAGE>

constitute an additional contractual obligation on the part of the Company
regardless of whether the Warrant that was lost, stolen, destroyed, or mutilated
shall be enforceable by anyone at any time.

      3.   ADJUSTMENT OF WARRANT PRICE AND NUMBER OF WARRANT SECURITIES.

      The number and kind of securities purchasable upon the exercise of each
Warrant and the Warrant Securities shall be subject to adjustment from time to
time upon the happening of certain events, as hereinafter defined.

           (a) The number of Warrant Securities purchasable upon the exercise of
      each Warrant and the Exercise Price shall be subject to adjustment as
      follows:

                  (i) In case the Company shall (A) pay a dividend in shares of
           Common Stock or make a distribution in shares of Common Stock, (B)
           subdivide or split its outstanding shares of Common Stock, (C)
           combine its outstanding shares of Common Stock into a smaller number
           of shares of Common Stock or (D) issue by reorganization,
           reclassification or recapitalization of its shares of Common Stock
           other securities of the Company, the number of Warrant Securities
           purchasable upon exercise of each Warrant immediately prior thereto
           shall be adjusted so that the Holder of each Warrant shall be
           entitled to receive the kind and number of Warrant Securities or
           other securities of the Company which such Holder would have owned or
           have been entitled to receive after the happening of any of the
           events described above, had such Warrant been exercised immediately
           prior to the happening of such event or any record date with respect
           thereto. An adjustment made pursuant to this paragraph (i) shall
           become effective immediately after the effective date of such event
           retroactive to the record date, if any, for such event.

                  (ii) In case the Company shall distribute to all holders of
           its shares of Common Stock evidences of its indebtedness or assets
           (excluding cash dividends or distributions payable out of
           consolidated earnings or earned surplus and dividends or
           distributions referred to in paragraph (i) above) or rights, options
           or warrants or convertible or exchangeable securities containing the
           right to subscribe for or purchase shares of Common Stock, then in
           each case the number of Warrant Securities thereafter purchasable
           upon the exercise of each Warrant shall be determined by multiplying
           the number of Warrant Securities theretofore purchasable upon the
           exercise of each Warrant, by a fraction, of which the numerator shall
           be the then current market price per share of Common Stock (as
           defined in Section 3(a)(iii) hereof) on the date of such
           distribution, and of which the denominator shall be the then current
           market price per share of Common Stock, less the then fair value (as
           determined by the Board of Directors of the Company, whose
           determination shall be conclusive) of the portion of the assets or
           evidences of indebtedness so distributed or of such subscription
           rights, options or warrants, or of such convertible or exchangeable
           securities applicable to one share of Common Stock. Such adjustment
           shall be made whenever any such distribution is made, and shall
           become effective on the date of distribution retroactive to the
           record date for the determination of stockholders entitled to receive
           such distribution.

                  (iii) For the purpose of any computation under Section
           3(a)(iii) and Section 7 hereof, the current market price per share of
           Common Stock at any date shall be the average closing price of the
           Common Stock (if then traded in the over-the-counter market) or the
           average closing price of the Common Stock (if then traded on NASDAQ's
           National Market System or on a national securities exchange) for the
           five consecutive trading days ending the day prior to the date as of
           which such computation is made. If the Common Stock is not so listed
           or admitted to unlisted trading privileges and closing prices are not
           so reported, the current market price per share shall be determined
           in such reasonable manner as may be prescribed by the Board of
           Directors of the Company.

                  (iv) No adjustment in the number of Warrant Securities
           purchasable hereunder shall be required unless such adjustment would
           require an increase or decrease of at least one percent (1%) in the
           number of Warrant Securities purchasable upon the exercise of this
           Warrant; provided, however, that any adjustments which by reason of
           this Section 3(a)(iv) are not required to be made shall be carried

                                       95

<PAGE>

           forward and taken into account in any subsequent adjustment. All
           calculations shall be made to the nearest one-thousandth of a share.

                  (v) Whenever the number of Warrant Securities purchasable upon
           the exercise of this Warrant is adjusted, as herein provided, the
           Exercise Price payable upon exercise of this Warrant in effect
           immediately prior to such adjustment, shall be adjusted by
           multiplying such Exercise Price immediately prior to such adjustment
           by a fraction, of which the numerator shall be the number of Warrant
           Securities purchasable upon the exercise of this Warrant immediately
           prior to such adjustment, and of which the denominator shall be the
           number or Warrant Securities so purchasable immediately thereafter.

                  (vi) For the purpose of this Section 3(a), the term "shares of
           Common Stock" shall mean (i) the class of stock designated as the
           Common Stock of the Company at the date of this Warrant, or (ii) any
           other class of stock resulting from successive changes or
           reclassification of such shares consisting solely of changes in par
           value, or from par value to no par value, or from no par value to par
           value. In the event that at any time, as a result of an adjustment
           made pursuant to Section 3(a)(i) above, the Holders shall become
           entitled to purchase any shares of the Company other than shares of
           Common Stock, thereafter the number of such other shares so
           purchasable upon exercise of this Warrant and the Exercise Price of
           such shares shall be subject to adjustment from time to time in a
           manner and on terms as nearly equivalent as practicable to the
           provisions with respect to the Warrant Securities contained in
           Section 3(a)(i) through Section 3(a)(v) inclusive, above, and the
           provisions of Sections 3(b) and 3(c) hereof, with respect to the
           Warrant Securities, shall apply on like terms to any such other
           shares.

      (b) Whenever the number of Warrant Securities purchasable upon the
exercise of this Warrant or the Exercise Price of such Warrant Securities is
adjusted, as herein provided, the Company shall promptly mail by first class
mail, postage prepaid, to each Holder notice of such adjustment or adjustments
and a certificate of a firm of independent public accountants selected by the
Board of Directors of the Company (who may be the regular accountants employed
by the Company) setting forth the number of Warrant Securities purchasable upon
the exercise of this Warrant and the Exercise Price of such Warrant Securities
after such adjustment, setting forth a brief statement of the facts requiring
such adjustment and setting forth the computation by which such adjustment was
made. Such certificate shall be conclusive of the correctness of such
adjustment.

      (c) Except as provided in subsection (a), no adjustment in respect of any
cash dividend shall be made during the term of this Warrant or upon its
exercise.

      (d) In case of any consolidation of the Company with or merger of the
Company into another corporation or in case of any sale or conveyance to another
corporation of the property of the Company as an entirety or substantially as an
entirety, the Company or such successor or purchasing corporation, as the case
may be, shall agree that each Holder shall have the right thereafter upon
payment of the Exercise Price in effect immediately prior to such action to
purchase upon exercise of this Warrant the kind and amount of shares and other
securities and property which such Holder would have owned or have been entitled
to receive after the happening of such consolidation, merger, sale or conveyance
had such Warrant been exercised immediately prior to such action. The Company
shall mail by first class mail, postage prepaid, to each Holder, notice of the
execution of any such agreement. Such agreement shall provide for adjustments,
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Section 3. The provisions of this Section 3(d) shall
similarly apply to successive consolidations, mergers, sales or conveyances.

      (e) Irrespective of any adjustments in the Exercise Price or the number or
kind of shares purchasable upon the exercise of the Warrant, any certificate
theretofore or thereafter issued may continue to express the same price and
number and kind of shares as are stated in this Warrant.

                                       96

      4. NOTICE TO HOLDERS. If, prior to the expiration of this Warrant either
by its terms or by its exercise in full, any of the following shall occur:

            (a) the Company shall declare a dividend or authorize any other
      distribution on its Common Stock; or

            (b) the Company shall authorize the granting to the shareholders of
      its Common Stock of rights to subscribe for or purchase any securities or
      any other similar rights; or

            (c) any reclassification, reorganization or similar change of the
      Common Stock, or any consolidation or merger to which the Company is a
      party, or the sale, lease, or exchange of any significant portion of the
      assets of the Company; or

            (d) the voluntary or involuntary dissolution, liquidation or winding
      up of the Company; or

            (e) any purchase, retirement or redemption by the Company of its
      Common Stock;

then, and in any such case, the Company shall deliver to the Holder or Holders
written notice thereof at least 30 days prior to the earliest applicable date
specified below with respect to which notice is to be given, which notice shall
state the following:

            (i) the date on which a record is to be taken for the purpose of
      such dividend, distribution or rights, or, if a record is not to be taken,
      the date as of which the shareholders of Common Stock of record to be
      entitled to such dividend, distribution or rights are to be determined;

            (ii) the date on which such reclassification, reorganization,
      consolidation, merger, sale, transfer, dissolution, liquidation, winding
      up or purchase, retirement or redemption is expected to become effective,
      and the date, if any, as of which the Company's shareholders of Common
      Stock of record shall be entitled to exchange their Common Stock for
      securities or other property deliverable upon such reclassification,
      reorganization, consolidation, merger, sale, transfer, dissolution,
      liquidation, winding up, purchase, retirement or redemption; and

            (iii) if any matters referred to in the foregoing clauses (i) and
      (ii) are to be voted upon by shareholders of Common Stock, the date as of
      which those shareholders to be entitled to vote are to be determined.

      5. RESERVATION OF WARRANT SECURITIES. The Company hereby agrees that at
all times prior to December 11, 2002, it will have authorized and will reserve
and keep available for issuance and delivery to the Holder that number of shares
of its Common Stock that may be required from time to time for issuance and
delivery upon the exercise of the then unexercised portion of this Warrant.

      6. TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933.

      (a) This Warrant, the Warrant Securities, and all other securities issued
or issuable upon exercise of this Warrant, may not be offered, sold or
transferred, in whole or in part, except in compliance with the Act, and except
with the express written approval of the Company and in compliance with all
applicable state securities statutes.

      (b) The Company may cause the following legend, or its equivalent, to be
set forth on each certificate representing the Warrant Securities, or any other
security issued or issuable upon exercise of this Warrant, not theretofore
distributed to the public or sold to underwriters, as defined by the Act, for
distribution to the public:

                                       97

<PAGE>

      "The shares represented by this Certificate have not been registered under
      the Securities Act of 1933 ("the Act") and are 'restricted securities' as
      that term is defined in Rule 144 under the Act. The shares may not be
      offered for sale, sold or otherwise transferred except pursuant to an
      effective registration statement under the Act or pursuant to an exemption
      from registration under the Act, the availability of which is to be
      established to the satisfaction of the Company."

      7. FRACTIONAL SHARES. The Company shall not be required to issue
fractional Warrant Securities on any exercise of this Warrant. The number of
full Warrant Securities which shall be issuable upon the exercise of Warrants
shall be computed on the basis of the aggregate number of Warrant Securities
purchasable on exercise of the Warrant so presented. If any fraction of Warrant
Securities would, except for the provisions of this Section 7, be issuable on
the exercise of any Warrant (or specified portion thereof), the Company shall
pay an amount in cash equal to the then current market price per Common Share
(as defined in Section 3(a)(iii) above) multiplied by such fraction.

      8. RIGHTS OF THE HOLDER. The Holder shall not be entitled to any rights as
a shareholder in the Company by reason of this Warrant, either at law or equity,
including, without limitation, the right to vote or to receive dividends or
other distributions, and shall not be entitled to receive any notice of any
proceeding of the Company, except as specifically provided for herein.

      9. WARRANT SECURITIES TO BE FULLY PAID. The Company covenants that all
Warrant Securities that may be issued and delivered to a Holder of this Warrant
upon the exercise of this Warrant and payment in full of the Exercise Price will
be, upon such delivery, validly and duly issued, fully paid and nonassessable.

      10. NOTICES. All notices, certificates, requests, or other similar items
provided for in this Warrant shall be in writing and shall be personally
delivered or deposited in the United States mail, postage prepaid, addressed to
the respective party as indicated in the portions of this Warrant preceding
Section 1. All notices shall be deemed to be delivered upon personal delivery or
upon the expiration of three business days following deposit in the United
States mail, postage prepaid. The addresses of the parties may be changed, and
addresses of other Holders and holders of Warrant Securities may be specified,
by written notice delivered pursuant to this Section 10. The Company's principal
office shall be deemed to be the address provided pursuant to this Section for
the delivery of notices to the Company.

      11. APPLICABLE LAW. This Warrant shall be governed by and construed in
accordance with the laws of the State of Florida, without reference to its
conflict of laws rules and principles, and courts and arbitration tribunals
located in or near Fort Myers, Florida shall have exclusive jurisdiction over
all disputes arising hereunder.

      12. ARBITRATION. The Company and the Holder, and by receipt of this
Warrant or any Warrant Securities, all subsequent Holders or holders of Warrant
Securities, agree to submit all controversies, claims, disputes and matters of
difference with respect to this Warrant, including, without limitation, the
application of this Section 12 to arbitration in Fort Myers, Florida, according
to the rules and practices of the American Arbitration Association from time to
time in force and if such arbitration can not be held in Fort Myers, Florida,
then it shall be held in the location nearest to Fort Myers, Florida, where such
arbitration may be maintained; provided, however, that if such rules and
practices conflict with the applicable procedures of Florida courts of general
jurisdiction or any other provisions of Florida law then in force, those Florida
rules and provisions shall govern. This agreement to arbitrate shall be
specifically enforceable. Arbitration may proceed in the absence of any party if
notice of the proceeding has been given to that party. The parties agree to
abide by all awards rendered in any such proceeding. These awards shall be final
and binding on all parties to the extent and in the manner provided by the rules
of civil procedure enacted in Florida. All awards may be filed, as a basis of
judgment and of the issuance of execution for its collection, with the clerk of
one or more courts, state or federal, having jurisdiction over either the party
against whom that award is rendered or its property. No party shall be
considered in default hereunder during the pendency of arbitration proceedings
relating to that default.

      13. MISCELLANEOUS PROVISIONS.
