                                                                   EXHIBIT 10.24

                                STOCK OPTION PLAN

              (Attachment to Explanatory Memorandum for Resolutions
                     included in Notice of Special Meeting)


1. Adoption and Purpose of the Plan. This stock option plan, to be known as the
"Catuity Inc. Stock Option Plan" (but referred to herein as the "Plan") has been
adopted by the board of directors (the "Board") of Catuity Inc., a Delaware
corporation (the "Company"), and is subject to the approval of its stockholders
pursuant to section 7 below. The purpose of this Plan is to advance the
interests of the Company and its stockholders by enabling the Company to attract
and retain qualified directors, officers, employees, independent contractors,
consultants and advisers by providing them with an opportunity for investment in
the Company. The options that may be granted hereunder ("Options") represent the
right by the grantee thereof (each, including any permitted transferee, an
"Optionee") to acquire shares of the Company's common stock ("Shares" which if
acquired pursuant to the exercise of an Option will be referred to as "Option
Shares") subject to the terms and conditions of this Plan and a written
agreement between the Company and the Optionee to evidence each such Option (an
"Option Agreement").

2. Certain Definitions. The defined terms set forth in Exhibit A attached hereto
and incorporated herein (together with other capitalized terms defined elsewhere
in this Plan) will govern the interpretation of this Plan.

3. Eligibility. The Company may grant Options under this Plan only to (i)
persons who, at the time of such grant, are directors, officers, and employees
of the Company and/or any of its Subsidiaries, and (ii) persons who, and
entities which, at the time of such grant, are independent contractors,
consultants or advisers of the Company and/or any of its Subsidiaries
(collectively, "Eligible Participants"). No person will be an Eligible
Participant following his or her Termination of Eligibility Status and no Option
may be granted to any person other than an Eligible Participant. There is no
limitation on the number of Options that may be granted to an Eligible
Participant.

4. Option Pool; Shares Reserved for Options. In no event will the Company issue,
in the aggregate, more than Seven Hundred and Fifty Thousand (750,000) Shares
(the "Option Pool") pursuant to the exercise of all Options granted under this
Plan, exclusive of those Option Shares that may be reacquired by the Company by
re-purchase or otherwise; provided that in order to comply with the requirements
of Section 260.140.45 of Title 10 of the California Code of Regulations (the

                                                                    CATUITY INC.
--------------------------------------------------------------------------------

total number of Shares provided for under any stock bonus or similar plan of the
Company in the aggregate exceed 30% of the total number of then issued and
outstanding Shares of the Company (or such higher percentage as has been
approved by the holders of at least two-thirds of the outstanding Shares of the
Company (including all securities convertible into Shares) entitled to vote), as
calculated in accordance with the conditions and exclusions of the 30% Rule. At
all times while Options granted under this Plan are outstanding, the Company
will reserve for issuance for the purposes hereof, a sufficient number of
authorized and unissued Shares to fully satisfy the Company's obligations under
all such outstanding Options. 5. Administration. This Plan will be administered
and interpreted by the Board, or by a committee consisting of two or more
members of the Board, appointed by the Board for such purpose (the Board, or
such committee, referred to herein as the "Administrator"). Subject to the
express terms and conditions hereof, the Administrator is authorized to
prescribe, amend and rescind rules and regulations relating to this Plan, and to
make all other determinations necessary or advisable for its administration and
interpretation. Specifically, the Administrator will have full and final
authority in its discretion, subject to the specific limitations on that
discretion as are set forth herein and in the Certificate of Incorporation and
By-laws of the Company, at any time:

          (a) to select and approve the Eligible Participants to whom Options
     will be granted from time to time hereunder;

          (b) to determine the Fair Market Value of the Shares as of the Grant
     Date for any Option that is granted hereunder;

          (c) with respect to each Option it decides to grant, to determine the
     terms and conditions of that Option, to be set forth in the Option
     Agreement evidencing that Option (the form of which also being subject to
     approval by the Administrator), which may vary from the "default" terms and
     conditions set forth in section 6 below, except to the extent otherwise
     provided in this Plan, including, without limitation, as follows:

               (i) the total number of Option Shares that may be acquired by the
          Optionee pursuant to the Option;

               (ii) if the Option satisfies the conditions under Section 422(b)
          of the Code, whether the Option will be treated as an ISO;

               (iii) the per share purchase price to be paid to the Company by
          the Optionee to acquire the Option Shares issuable upon exercise of
          the Option (the "Option Price"), provided that the Option Price will
          not be less than 85% of the Fair Market Value of the Shares as of the


                                     Page 2

<PAGE>   3
                                                                    CATUITY INC.
--------------------------------------------------------------------------------

          Grant Date, unless the Optionee is a 10% stockholder, in which case
          the Option Price will not be less than 110% of such Fair Market Value;

               (iv) the maximum period or term during which the Option will be
          exercisable (the "Option Term"), provided that in no event may the
          Option Term be longer than 10 years from the Grant Date;

               (v) the maximum period following any Termination of Eligibility
          Status, whether resulting from an Optionee's death, disability or any
          other reason, during which period (the "Grace Period") the Option will
          be exercisable, subject to Vesting and to the expiration of the Option
          Term, provided that in no event may the Administrator designate a
          Grace Period that is shorter than six months after such Termination of
          Eligibility Status by reason of the Optionee's death or disability, or
          30 days after such Termination of Eligibility for any other reason,
          except in the event of a Termination for Cause, in which case no Grace
          Period will be required (i.e., the Option will terminate immediately);

               (vi) whether to accept a promissory note or other form of legal
          consideration in addition to cash as payment for all or a portion of
          the Option Price and/or Tax Withholding Liability to be paid by the
          Optionee upon the exercise of an Option granted hereunder;

               (vii) the conditions (e.g., the passage of time or the occurrence
          of events), if any, that must be satisfied prior to the vesting of the
          right to exercise all or specified portions of an Option (such
          portions being described as the number of Option Shares, or the
          percentage of the total number of Option Shares that may be acquired
          by the Optionee pursuant to the Option; the vested portion being
          referred to as a "Vested Option" and the unvested portion being
          referred to as an "Unvested Option"), provided that no such conditions
          (except an Optionee's Termination of Eligibility Status, after which
          no Unvested Option will become a Vested Option) may be imposed which
          prevents an Optionee who is an employee, but who is neither an officer
          or director, of the Company or any of its Subsidiaries, from
          purchasing at least 20% of the Option Shares initially subject to the
          Option as of the first anniversary of the Grant Date, and as of each
          anniversary thereafter, such that by the fifth anniversary of the
          Grant Date (assuming no such Termination of Eligibility Status) the
          entire Option would be deemed a Vested Option; and

               (viii) in addition, or as an alternative, to imposing conditions
          on the right to exercise an Option as provided in section 5(c)(vii)
          above, whether any portion of the Option Shares acquired by an
          Optionee

                                                                    CATUITY INC.
--------------------------------------------------------------------------------

          upon exercise of an Option will be subject to repurchase by the
          Company or its assigns at the Option Price paid for such Shares or at
          some other price that may be less than the Fair Market Value of such
          Shares (such Shares, if subject to repurchase at less than Fair Market
          Value, being referred to as "Unvested Shares") following a Termination
          of Eligibility Status or other designated event, and the conditions
          (e.g., the passage of time or the occurrence of events), if any, that
          must be satisfied for such Shares to be no longer subject to such
          right of repurchase at less than Fair Market Value (such Shares being
          referred to as "Vested Shares"); provided that no such conditions
          (except an Optionee's Termination of Eligibility Status, after which
          no Unvested Shares will become Vested Shares) may be imposed which
          prevent Unvested Shares held by an employee, who is neither an officer
          or director, of the Company and/or any of its Subsidiaries, from
          becoming Vested Shares at the rate of at least twenty percent (20%)
          per year following the Grant Date, such that by the fifth anniversary
          of the Grant Date (assuming no earlier Termination of Eligibility
          Status) all of the Shares would be deemed Vested Shares; and

          (d) to delegate all or a portion of the Administrator's authority
     under sections 5(a), (b) and (c) above to one or more members of the Board
     who also are executive officers of the Company, and subject to such
     restrictions and limitations as the Administrator may decide to impose on
     such delegation.

6. Default Terms and Conditions of Option Agreements. Unless otherwise expressly
provided in an Option Agreement based on the Administrator's determination
pursuant to section 5(c) above, the following terms and conditions will be
deemed to apply to each Option as if expressly set forth in the Option
Agreement:

     6.1 ISO. No Option will be treated as an ISO unless treatment as an ISO is
  expressly provided for in an Option Agreement and such Option satisfies the
  conditions of Section 422(b) of the Code.

     6.2 Option Term. The Option Term will be for a period of 10 years beginning
  on the Grant Date, except that in the case of an ISO granted to a 10%
  stockholder, the Option Term will be for a period of 5 years beginning on the
  Grant Date.

     6.3 Grace Periods.  Following a Termination of Eligibility Status:

          (a) the Grace Period will be thirty (30) days, unless the Termination
     of Eligibility Status is a result of a Termination for Cause or the death
     or disability of the Optionee;


                                     Page 4
<PAGE>   5
                                                                    CATUITY INC.
--------------------------------------------------------------------------------

          (b) the Grace Period will be six months if the Termination of
     Eligibility Status is a result of the death or disability of the Optionee;
     and

          (c) the Option will terminate, and there will be no Grace Period,
     effective immediately as of the date and time of a Termination for Cause of
     the Optionee, regardless of whether the Option is Vested or Unvested.

     6.4 Vesting. The Option initially will be deemed an entirely Unvested
  Option, but portions of the Option will become a Vested Option on the
  following schedule:

          (a) twenty percent (20%) will become a Vested Option as of the first
     anniversary of the "Vesting Start Date" specified in the Option Agreement
     (which may be earlier but may not be later than the Grant Date specified
     therein); and

          (b) ten percent (10%) of the Option will become a Vested Option on the
     last day of each six-month period thereafter, such that the Option will
     become a fully Vested Option as of the fifth anniversary of the Vesting
     Start Date;

provided that the Optionee does not suffer a Termination of Eligibility Status
prior to each such vesting date and provided further that additional vesting
will be suspended during any period while the Optionee is on a leave of absence
from the Company or its Subsidiaries, as determined by the Administrator.

     6.5 Exercise of the Option; Issuance of Share Certificate.

          (a) The portion of the Option that is a Vested Option may be exercised
     by giving written notice thereof to the Company, on such form as may be
     specified by the Administrator, but in any event stating: the Optionee's
     intention to exercise the Option; the date of exercise; the number of full
     Option Shares to be purchased (which number will be no less than 100
     Shares, without regard to adjustments to the number of Shares subject to
     the Option pursuant to section 8 below, or, if less, all of the remaining
     Shares subject to the Option); the amount and form of payment of the Option
     Price; and such assurances of the Optionee's investment intent as the
     Company may require to ensure that the transaction complies in all respects
     with the requirements of the 1933 Act and other applicable securities laws.
     The notice of exercise will be signed by the person or persons exercising
     the Option. In the event that the Option is being exercised by the
     representative of the Optionee, the notice will be accompanied by proof
     satisfactory to the Company of the representative's right to exercise the
     Option. The notice of exercise will be accompanied by full payment of the
     Option Price for the number of Option Shares to be purchased, in United
     States dollars, in cash, by check made payable to the


                                     Page 5

<PAGE>   6
                                                                    CATUITY INC.
--------------------------------------------------------------------------------

     Company, or by delivery of such other form of payment (if any) as approved
     by the Administrator in the particular case. Payment also may be made by
     delivering a copy of irrevocable instructions to a broker to deliver
     promptly to the Company the amount of sale or loan proceeds sufficient to
     pay the Option Price and, if required, the amount of any Tax Withholding
     Liability.

          (b) To the extent required by applicable federal, state, local or
     foreign law, and as a condition to the Company's obligation to issue any
     Shares upon the exercise of the Option in full or in part, the Optionee
     will make arrangements satisfactory to the Company for the payment of any
     applicable Tax Withholding Liability that may arise by reason of or in
     connection with such exercise. Such arrangements may include, in the
     Company's sole discretion, that the Optionee tender to the Company the
     amount of such Tax Withholding Liability, in cash, by check made payable to
     the Company, or in the form of such other payment as may be approved by the
     Administrator, in its discretion pursuant to section 5(c)(vi) above.

          (c) After receiving a proper notice of exercise and payment of the
     applicable Option Price and Tax Withholding Liability, the Company will
     cause to be issued a certificate or certificates for the Option Shares as
     to which the Option has been exercised, registered in the name of the
     person rightfully exercising the Option and the Company will cause such
     certificate or certificates to be delivered to such person.

     6.6 Compliance with Law. Notwithstanding any other provision of this Plan,
  Options may be granted pursuant to this Plan, and Option Shares may be issued
  pursuant to the exercise thereof by an Optionee, only after and on the
  condition that there has been compliance with all applicable federal and state
  securities laws. The Company will not be required to list, register or qualify
  any Option Shares upon any securities exchange, under any applicable state,
  federal or foreign law or regulation, or with the Securities and Exchange
  Commission or any state agency, or secure the consent or approval of any
  governmental regulatory authority, except that if at any time the Board
  determines, in its discretion, that such listing, registration or
  qualification of the Option Shares, or any such consent or approval, is
  necessary or desirable as a condition of or in connection with the exercise of
  an Option and the purchase of Option Shares thereunder, that Option may not be
  exercised, in whole or in part, unless and until such listing, registration,
  qualification, consent or approval is effected or obtained free of any
  conditions that are not acceptable to the Board, in its discretion. However,
  the Company will seek to register or qualify with, or as may be provided by
  applicable local law, file for and secure an exemption from such registration
  or qualification requirements from, the applicable securities administrator
  and other officials of each jurisdiction in which an Eligible Participant
  would be granted an Option hereunder prior to such grant.

     6.7      Restrictions on Transfer.

                                                                    CATUITY INC.
--------------------------------------------------------------------------------

          (a) Options Nontransferable. No Option will be transferable by an
     Optionee otherwise than by will or the laws of descent and distribution.
     During the lifetime of a natural person who is granted an Option under this
     Plan, the Option will be exercisable only by him or her. Notwithstanding
     anything else in this Plan to the contrary, no Option Agreement will
     contain any provision which is contrary to, or which modifies, the
     provisions of this section 6.7(a).

          (b) Prohibited Transfers. Prior to the Initial Registration, no Holder
     of any Option Shares may Transfer such Shares, or any interest therein,
     other than in full compliance with all applicable securities laws and any
     applicable restrictions on Transfer provided in the Company's Certificate
     of Incorporation and/or Bylaws, which will be deemed incorporated by
     reference into this Plan. All Transfers of Option Shares not complying with
     the specific limitations and conditions set forth in this section 6.7 are
     expressly prohibited. Any prohibited Transfer is void and of no effect, and
     no purported transferee in connection therewith will be recognized as a
     Holder of Option Shares for any purpose whatsoever. Should such a Transfer
     purport to occur, the Company may refuse to carry out the Transfer on its
     books, attempt to set aside the Transfer, enforce any undertakings or
     rights under this Plan, or exercise any other legal or equitable remedy.

          (c) Conditions to Transfer. It will be a condition to any Transfer of
     any Option Shares that:

               (i) the transferee of the Shares will execute such documents as
          the Company may reasonably require to ensure that the Company's rights
          under this Plan, and any applicable Option Agreement, are adequately
          protected with respect to such Shares, including, without limitation,
          the transferee's agreement to be bound by all of the terms and
          conditions of this Plan and such Agreement, as if he or she were the
          original Holder of such Shares; and

               (ii) the Company is satisfied that such Transfer complies in all
          respects with the requirements imposed by applicable state and federal
          securities laws and regulations.

          (d) Market Standoff. If in connection with any public offering of
     securities of the Company (or any Successor Entity), the underwriter or
     underwriters managing such offering so requests, then each Optionee and
     each Holder of Option Shares will agree to not sell or otherwise Transfer
     any such Shares (other than Shares included in such underwriting) without
     the prior written consent of such underwriter, for such period of time as
     may be requested by the underwriter commencing on the effective date of the
     registration statement filed with the Securities and Exchange Commission


                                     Page 7
<PAGE>   8
                                                                    CATUITY INC.
--------------------------------------------------------------------------------

     in connection with such offering but in no event longer than the period of
     time that the officers and directors of the Company are generally
     prohibited from Transferring their Shares in connection with such public
     offering.

     6.8 Change of Control Transactions. In the event of a Change of Control
  Transaction, the Company shall endeavor to cause the Successor Entity (or its
  parent or its Subsidiary) in such transaction either to assume all of the
  Options which have been granted hereunder and which are outstanding as of the
  consummation of such transaction ("Change of Control Closing"), or to issue
  (or cause to be issued) in substitution thereof comparable options of such
  Successor Entity (or of its parent or its Subsidiary). If the Successor Entity
  (or its parent or its Subsidiary) is unwilling to either assume such Options
  or grant comparable options in substitution for such Options, on terms that
  are acceptable to the Company as determined by the Board in the exercise of
  its discretion, then the Board may cancel all outstanding Vested Options, and
  terminate this Plan, effective as of the Change of Control Closing, provided
  that (i) it will notify all Optionees of the proposed Change of Control
  Transaction a reasonable amount of time prior to the Change of Control Closing
  so that each Optionee will be given the opportunity to exercise all Vested
  Options prior to the Change of Control Closing and (ii) any and all Unvested
  Options will survive the termination of the Plan without impairment. For
  purposes of this section 6.8, the term "Change of Control Transaction" means a
  Business Combination in which less than (50%) of the outstanding voting
  securities of the Successor Entity immediately following the Closing of the
  Business Combination are beneficially held by those persons and entities in
  the same proportion as such persons and entities beneficially held the voting
  securities of the Company immediately prior to such transaction; the term
  "Business Combination" means a transaction or series of transactions
  consummated within any period of 90 days resulting in (A) the sale of all or
  substantially all of the assets of the Company, (B) a merger or consolidation
  or other reorganization of which the Company or a Subsidiary is a merging
  party, or (C) the sale or other change of beneficial ownership of at least
  Thirty Three and One Third Percent of the outstanding voting securities of the
  Company.

     6.9 Additional Restrictions on Transfer: Investment Intent. By accepting an
  Option and/or Option Shares under this Plan, the Optionee will be deemed to
  represent, warrant and agree that, unless a registration statement is in
  effect with respect to the offer and sale of Option Shares: (i) neither the
  Option nor any such Shares will be freely tradeable and must be held
  indefinitely unless such Option and such Shares are either registered under
  the 1933 Act or an exemption from such registration is available; (ii) the
  Company is under no obligation to register the Option or any such Shares;
  (iii) upon exercise of the Option, the Optionee will purchase the Option
  Shares for his or her own account and not with a view to distribution within
  the meaning of the 1933 Act, other than as may be effected in compliance with
  the 1933 Act and the rules and regulations promulgated thereunder; (iv) no one
  else will have any beneficial interest in the

                                     Page 8
<PAGE>   9
                                                                    CATUITY INC.
--------------------------------------------------------------------------------

  Option Shares; (v) the Optionee has no present intention of disposing of the
  Option Shares at any particular time; and (vi) neither the Option nor the
  Shares have been qualified under the securities laws of any state and may only
  be offered and sold pursuant to an exception from qualification under
  applicable state securities laws.

    6.9 Stock Certificates: Legends. Certificates representing Option Shares
  will bear all legends required by law and necessary or appropriate in the
  Administrator's discretion to effectuate the provisions of this Plan and of
  the applicable Option Agreement. The Company may place a "stop transfer" order
  against Option Shares until full compliance with all restrictions and
  conditions set forth in this Plan, in any applicable Option Agreement and in
  the legends referred to in this section 6.10.

    6.10 Notices. Any notice to be given to the Company under the terms of an
  Option Agreement will be addressed to the Company at its principal executive
  office, Attention: Secretary, or at such other address as the Company may
  designate in writing. Any notice to be given to an Optionee will be addressed
  to him or her at the address provided to the Company by the Optionee. Any such
  notice will be deemed to have been duly given if and when enclosed in a
  properly sealed envelope, addressed as aforesaid, deposited, postage prepaid,
  in a post office or branch post office regularly maintained by the local
  postal authority.

    6.11 Other Provisions. Each Option Agreement may contain such other terms,
  provisions and conditions, including restrictions on the Transfer of Option
  Shares, and rights of the Company to repurchase such Shares, not inconsistent
  with this Plan and applicable law, as may be determined by the Administrator
  in its sole discretion.

    6.12 Specific Performance. Under those circumstances in which the Company
  chooses to timely exercise its rights to repurchase Option Shares as provided
  herein or in any Option Agreement, the Company will be entitled to receive
  such Shares in specie in order to have the same available for future issuance
  without dilution of the holdings of other stockholders of the Company. By
  accepting Option Shares, the Holder thereof therefore acknowledges and agrees
  that money damages will be inadequate to compensate the Company and its
  stockholders if such a repurchase is not completed as contemplated hereunder
  and that the Company will, in such case, be entitled to a decree of specific
  performance of the terms hereof or to an injunction restraining such holder
  (or such Holder's personal representative) from violating this Plan or Option
  Agreement, in addition to any other remedies that may be available to the
  Company at law or in equity.

7. Term of the Plan. This Plan will become effective on the date of its adoption
by the Board, provided that this Plan is approved by the stockholders of the
Company (excluding Option Shares issued by the Company pursuant to the

                                                                    CATUITY INC.
--------------------------------------------------------------------------------

exercise of Options granted under this Plan) within 12 months before or after
that date. If this Plan is not so approved by the stockholders of the Company
within that 12-month period of time, any Options granted under this Plan will be
rescinded and will be void. This Plan will expire on the tenth (10th)
anniversary of the date of its adoption by the Board or its approval by the
stockholders of the Company, whichever is earlier, unless it is terminated
earlier pursuant to section 11 of this Plan, after which no more Options may be
granted under this Plan, although all outstanding Options granted prior to such
expiration or termination will remain subject to the provisions of this Plan,
and no such expiration or termination of this Plan will result in the expiration
or termination of any such Option prior to the expiration or early termination
of the applicable Option Term.

8. Adjustments Upon Changes in Stock. In the event of any change in the
outstanding Shares of the Company as a result of a stock split, reverse stock
split, stock bonus or distribution, recapitalization, combination or
reclassification, appropriate proportionate adjustments as permitted by any
listing rules applying to the Company, will be made in: (i) the aggregate number
of Shares that are reserved for issuance in the Option Pool pursuant to section
4 above, under outstanding Options or future Options granted hereunder; (ii) the
Option Price and the number of Option Shares that may be acquired under each
outstanding Option granted hereunder; and (iii) other rights and matters
determined on a per share basis under this Plan or any Option Agreement
evidencing an outstanding Option granted hereunder. Any such adjustments will be
made only by the Board, and when so made will be effective, conclusive and
binding for all purposes with respect to this Plan and all Options then
outstanding. No such adjustments will be required by reason of the issuance or
sale by the Company for cash or other consideration of additional Shares or
securities convertible into or exchangeable for Shares. The rights of all
Optionee's will be changed to the extent necessary to comply with any listing
rules applying to the re-organisation of capital at the time of the
re-organisation.

9. Modification, Extension and Renewal of Options. Subject to the terms and
conditions and within the limitations of this Plan, the Administrator may
modify, extend or renew outstanding Options granted under this Plan, or accept
the surrender of outstanding Options (to the extent not theretofore exercised)
and authorize the granting of new Options in substitution therefor (to the
extent not theretofore exercised). Notwithstanding the foregoing, no
modification of any Option will, without the consent of the Optionee, reduce the
number of Shares covered by the Option, defer vesting of the Option, or convert
a Vested Option to an Unvested Option.

10. Governing Law; Venue. The internal laws of the State of Delaware
(irrespective of its choice of law principles) will govern the validity of this
Plan, the construction of its terms and the interpretation of the rights and
duties of the parties hereunder and under any Option Agreement. Any party may
seek to

                                                                    CATUITY INC.
--------------------------------------------------------------------------------

enforce its rights under this Plan or any Option Agreement entered into
under this Plan in any court of competent jurisdiction located within the
judicial district in which the Company then has a principal place of business.

11. Amendment and Discontinuance. The Board may amend, suspend or discontinue
this Plan at any time or from time to time; provided that no action of the Board
will, without the approval of the stockholders of the Company, materially
increase (other than by reason of an adjustment pursuant to section 8 hereof)
the maximum aggregate number of Option Shares in the Option Pool, materially
increase the benefits accruing to Eligible Participants, or materially modify
the category of, or eligibility requirements for persons who are Eligible
Participants. However, except as provided in section 6.8, no such action may
alter or impair any Option previously granted under this Plan without the
consent of the Optionee, nor may the number of Option Shares in the Option Pool
be reduced to a number that is less than the aggregate number of Option Shares
(i) that may be issued pursuant to the exercise of all outstanding and unexpired
Options granted hereunder, and (ii) that have been issued and are outstanding
pursuant to the exercise of Options granted hereunder.

12. Information Provided by Company. Prior to the date on which the Company is
required to file its annual financial statements with the Securities and
Exchange Commission under the Securities Exchange Act of 1934, the Company
annually will provide the Company's financial statements (which statements need
not be audited) to each Optionee who is an employee of the Company or any of its
Subsidiaries, and each Optionee will, by virtue of entering into an Option
Agreement, be deemed to have agreed (and to cause any investment advisers to
whom the Optionee proposes to make such information available to agree) to keep
such information confidential and not to use, disclose or copy such information
for any purpose whatsoever other than determining whether to exercise an Option.
The Company deems such financial statements to be the valuable trade secrets of
the Company, and in the event of any wrongful use, disclosure or other breach of
the obligation to maintain the confidentiality of such financial information,
the Company may seek to enforce all of its available legal and equitable rights
and remedies, and may notify local law enforcement officials that a criminal
misappropriation of the Company's trade secrets has taken place.

13. No Stockholder Rights. No rights or privileges of a stockholder in the
Company are conferred by reason of the granting of an Option. No Optionee will
become a stockholder in the Company with respect to any Option Shares unless and
until the Option has been properly exercised and the Option Price fully paid as
to the portion of the Option exercised. No Optionee will become entitled to
participate in any new issue of securities, other than securities issued under
section 8 of this Plan, unless and until the Option has been properly exercised
and the Option Price fully paid as to the portion of the Option exercised.
