Exhibit 4.3  

MITEK SYSTEMS, INC.

2002 STOCK OPTION PLAN  

        1.     PURPOSE. This Stock Option Plan (the "Plan") is intended to serve as an incentive to, and to encourage stock ownership by
certain eligible participants rendering services to Mitek Systems, Inc., a Delaware corporation, and certain affiliates as set forth below (the "Corporation"), so that they may acquire or
increase their proprietary interest in the Corporation and to encourage them to remain in the service of the Corporation. 

        2.     ADMINISTRATION. 

        2.1   Committee. The Plan shall be administered by the Board of Directors of the Corporation (the "Board of Directors"), or a
committee of two or more members appointed by the Board of Directors (the "Committee") who are Non-Employee Directors as defined in Rule 16b-3 promulgated under
Section 16 of the Securities Exchange Act of 1934 and an outside director as defined in Treasury Regulation § 1.162-27(e)(3). The Committee shall select one of its
members as Chairman and shall appoint a Secretary, who need not be a member of the Committee. The Committee shall hold meetings at such times and places as it may determine and minutes of such
meetings shall be recorded. Acts by a majority of the Committee in a meeting at which a quorum is present and acts approved in writing by a majority of the members of the Committee shall be valid acts
of the Committee. 

        2.2   Term. If the Board of Directors selects a Committee, the members of the Committee shall serve on the Committee for the
period of time determined by the Board of Directors and shall be subject to removal by the Board of Directors at any time. The Board of Directors may terminate the function of the Committee at any
time and resume all powers and authority previously delegated to the Committee. 

        2.3   Authority. The Committee shall have sole discretion and authority to grant options under the Plan to eligible
participants rendering services to the Corporation or any "parent" or "subsidiary" of the Corporation, as defined in Section 424 of the Internal Revenue Code of 1986, as amended (the "Code")
("Parent or Subsidiary"), at such times, under such terms and in such amounts as it may decide. For purposes of this Plan and any Stock Option Agreement (as defined below), the term "Corporation"
shall include any Parent or Subsidiary, if applicable. Subject to the express provisions of the Plan, the Committee shall have complete authority to interpret the Plan, to prescribe, amend and rescind
the rules and regulations relating to the Plan, to determine the details and provisions of any Stock Option Agreement, to accelerate any options granted under the Plan and to make all other
determinations necessary or advisable for the administration of the Plan. 

        2.4   Type of Option. The Committee shall have full authority and discretion to determine, and shall specify, whether the
eligible individual will be granted options intended to qualify as incentive options under Section 422 of the Code ("Incentive Options") or options which are not intended to qualify under
Section 422 of the Code ("Non-Qualified Options"); provided, however, that Incentive Options shall only be granted to employees of the Corporation, or a Parent or Subsidiary
thereof, and shall be subject to the special limitations set forth herein attributable to Incentive Options. 

        2.5   Interpretation. The interpretation and construction by the Committee of any provisions of the Plan or of any option
granted under the Plan shall be final and binding on all parties having an interest in this Plan or any option granted hereunder. No member of the Committee shall be liable for any action or
determination made in good faith with respect to the Plan or any option granted under the Plan. 

 

        3.     ELIGIBILITY. 

        3.1   General. All directors, officers, employees of and consultants to the Corporation, or any Parent or Subsidiary relative
to the Corporation's, or any Parent's or Subsidiary's management, operation or development shall be eligible to receive options under the Plan. The selection of recipients of options shall be within
the sole and absolute discretion of the Committee. No person shall be granted an Incentive Option under this Plan unless such person is an employee of the Corporation, or a Parent or Subsidiary on the
date of grant. No person shall be granted an option under this Plan unless such person has executed, if requested by the Committee, the grant representation letter set forth on Exhibit "A," as such
Exhibit may be amended by the Committee from time to time. No person shall be granted more than 500,000 options in any one year period. 

        3.2   Termination of Eligibility. 

        3.2.1 If
an optionee ceases to be employed by the Corporation, or its Parent or Subsidiary, is no longer an officer or member of the Board of Directors of the Corporation,
or no longer performs services for the Corporation, or its Parent or Subsidiary, for any reason (other than for "cause," as hereinafter defined, or such optionee's death), any option granted hereunder
to such optionee shall expire three months after the occurrence giving rise to such termination of eligibility (or 1 year in the event an optionee is "disabled," as defined in
Section 22(e)(3) of the Code) or upon the date it expires by its terms, whichever is earlier. Any option that has not vested in the optionee as of the date of such termination shall immediately
expire and shall be null and void. The Committee shall, in its sole and absolute discretion, decide, utilizing the provisions set forth in Treasury Regulations § 1.421-7(h),
whether an authorized leave of absence or absence for military or governmental service, or absence for any other reason, shall constitute termination of eligibility for purposes of this Section. 

        3.2.2 If
an optionee ceases to be employed by the Corporation, or its Parent or Subsidiary, is no longer an officer or member of the Board of Directors of the Corporation,
or no longer performs services for the Corporation, or its Parent or Subsidiary, and such termination is as a result of "cause," as hereinafter defined, then all options granted hereunder to such
optionee shall expire on the date of the occurrence giving rise to such termination of eligibility or upon the date it expires by its terms, whichever is earlier, and such optionee shall have no
rights with respect to any unexercised options. For purposes of this Plan, "cause" shall mean an optionee's personal dishonesty, misconduct, breach of fiduciary duty, incompetence, intentional failure
to perform stated obligations, willful violation of any law, rule, regulation or final cease and desist order, or any material breach of any provision of this Plan, any Stock Option Agreement or any
employment agreement. 

        3.3   Death of Optionee and Transfer of Option. In the event an optionee shall die, an option may be exercised (subject to the
condition that no option shall be exercisable after its expiration and only to the extent that the optionee's right to exercise such option had accrued at the time of the optionee's death) at any time
within six months after the optionee's death by the executors or administrators of the optionee or by any person or persons who shall have acquired the option directly from the optionee by bequest or
inheritance. Any option that has not vested in the optionee as of the date of death or termination of employment, whichever is earlier, shall immediately expire and shall be null and void. No option
shall be transferable by the optionee other than by will or the laws of intestate succession. 

        3.4   Limitation on Incentive Options. No person shall be granted any Incentive Option to the extent that the aggregate fair
market value of the Stock (as defined below) to which such options are exercisable for the first time by the optionee during any calendar year (under all plans of the Corporation as determined under
Section 422(d) of the Code) exceeds $100,000. 

2

 

        4.     IDENTIFICATION OF STOCK. The Stock, as defined herein, subject to the options shall be shares of the Corporation's
authorized but unissued or acquired or reacquired common stock (the "Stock"). The aggregate number of shares subject to outstanding options shall not exceed 1,000,000 shares of Stock (subject to
adjustment as provided in Section 6). If any option granted hereunder shall expire or terminate for any reason without having been exercised in full, the unpurchased shares subject thereto
shall again be available for purposes of this Plan. Notwithstanding the above, at no time shall the total number of shares of Stock issuable upon exercise of all outstanding options and the total
number of shares of Stock provided for under any stock bonus or similar plan of the Corporation exceed 30% as calculated in accordance with the conditions and exclusions of §260.140.45 of
Title 10, California Code of Regulations, based on the shares of the issuer which are outstanding at the time the calculation is made. 

        5.     TERMS AND CONDITIONS OF OPTIONS. Any option granted pursuant to the Plan shall be evidenced by an agreement ("Stock Option
Agreement") in such form as the Committee shall from time to time determine, which agreement shall comply with and be subject to the following terms and conditions: 

        5.1   Number of Shares. Each option shall state the number of shares of Stock to which it pertains. 

        5.2   Option Exercise Price. Each option shall state the option exercise price, which shall be determined by the Committee;
provided, however, that (i) the exercise price of any Incentive Option shall not be less than the fair market value of the Stock, as determined by the Committee, on the date of grant of such
option, (ii) the exercise price of any option granted to any person who owns more than 10% of the total combined voting power of all classes of the Corporation's stock, as determined for
purposes of Section 422 of the Code, shall not be less than 110% of the fair market value of the Stock, as determined by the Committee, on the date of grant of such option, and (iii) the
exercise price of any Non-Qualified Option shall not be less than 85% of the fair market value of the Stock, as determined by the Committee, on the date of grant of such option. In the
event that the fair market value of the price of the common stock declines below the price at which the option is granted, the Committee shall have the discretion and authority to cancel, reduce, or
otherwise modify the price of any unexercised option, including, but not limited to, a regrant of the option at a new price more commensurate with the fair market value of the stock. The Committee
must receive the approval of the Board of Directors before any action is taken in accordance with this provision. 

        5.3   Term of Option. The term of an option granted hereunder shall be determined by the Committee at the time of grant, but
shall not exceed ten years from the date of the grant. The term of any Incentive Option granted to an employee who owns more than 10% of the total combined voting power of all classes of the
Corporation's stock, as determined for purposes of Section 422 of the Code, shall in no event exceed five years from the date of grant. All options shall be subject to early termination as set
forth in this Plan. In no event shall any option be exercisable after the expiration of its term. 

        5.4   Method of Exercise. An option shall be exercised by written notice to the Corporation by the optionee (or successor in
the event of death) and execution by the optionee of an exercise representation letter in the form set forth on Exhibit "B," as such Exhibit may be amended by the Committee from time to time. Such
written notice shall state the number of shares with respect to which the option is being exercised and designate a time, during normal business hours of the Corporation, for the delivery thereof
("Exercise Date"), which time shall be at least 30 days after the giving of such notice unless an earlier date shall have been mutually agreed upon. At the time specified in the written notice,
the Corporation shall deliver to the optionee at the principal office of the Corporation, or such other appropriate place as may be determined by the Committee, a 

3

 

certificate
or certificates for such shares. Notwithstanding the foregoing, the Corporation may postpone delivery of any certificate or certificates after notice of exercise for such reasonable period
as may be required to comply with any applicable listing requirements of any securities exchange. In the event an option shall be exercisable by any person other than the optionee, the required notice
under this Section shall be accompanied by appropriate proof of the right of such person to exercise the option. 

        5.5   Medium and Time of Payment. The option exercise price shall be payable in full on or before the option Exercise Date in
any one of the following alternative forms: 

        5.5.1 Full
payment in cash or certified bank or cashier's check; 

        5.5.2 Subject
to Section 5.5.7 hereof, a Promissory Note (as defined below); 

        5.5.3 Full
payment in shares of Stock having a fair market value on the Exercise Date in the amount equal to the option exercise price; 

        5.5.4 Subject
to Section 5.5.7 hereof, through a special sale and remittance procedure pursuant to which the optionee shall concurrently provide irrevocable written
instruction to (a) a Corporation-designated brokerage firm to effect the immediate sale of the purchased shares and remit to the Corporation, out of the sale proceeds available on the
settlement date pursuant to an irrevocable assignment by the optionee, sufficient funds to cover the aggregate exercise price payable for the purchased shares plus all applicable Federal, state and
local income and employment taxes required to be withheld by the Corporation by reason of such exercise and (b) the Corporation to deliver the certificates for the purchased shares directly to
such brokerage firm in order to complete the sale. 

        5.5.5 A
combination of the consideration set forth in Sections 5.5.1, through 5.5.4 equal to the option exercise price; or 

        5.5.6 Any
other method of payment complying with the provisions of Section 422 of the Code with respect to Incentive Options, provided the terms of payment are
established by the Committee at the time of grant and any other method of payment established by the Committee with respect to Non-Qualified Options. 

        5.5.7 Notwithstanding
the foregoing, the methods of payment described in Section 5.5.2 and Section 5.5.4 shall not be available to any optionee classified as
"a director or executive officer (or equivalent thereof)" within the meaning of Section 402 of the Sarbanes-Oxley Act of 2002 ("Sarbanes-Oxley") at the time of the exercise, unless such
optionee provides to the Corporation a written opinion of counsel satisfactory to the Corporation that the proposed medium of payment is not prohibited by Sarbanes-Oxley. 

        5.6   Fair Market Value. The fair market value of a share of Stock on any relevant date shall be determined in accordance with
the following provisions: 

        5.6.1 If
the Stock at the time is neither listed nor admitted to trading on any stock exchange nor traded in the over-the-counter market, then the
fair market value shall be determined by the Committee after taking into account the factors found in § 260.140.50 of Title 10, California Code of Regulations and such other factors as the
Committee shall deem appropriate. 

        5.6.2 If
the Stock is not at the time listed or admitted to trading on any stock exchange but is traded in the over-the-counter market, the fair
market value shall be the mean between the highest bid and lowest asked prices (or, if such information is available, the closing selling price) of one share of Stock on the date in question in the
over-the-counter market, as such prices are reported by the National Association of Securities Dealers through its NASDAQ 

4

 

system
or any successor system. If there are no reported bid and asked prices (or closing selling price) for the Stock on the date in question, then the mean between the highest bid and lowest asked
prices (or the closing selling price) on the last preceding date for which such quotations exist shall be determinative of fair market value. 

        5.6.3 If
the Stock is at the time listed or admitted to trading on any stock exchange, then the fair market value shall be the closing selling price of one share of Stock on
the date in question on the stock exchange determined by the Committee to be the primary market for the Stock, as such price is officially quoted in the composite tape of transactions on such
exchange. If there is no sale of Stock on such exchange on the date in question, then the fair market value shall be the closing selling price on the exchange on the last preceding date for which such
quotation exists. 

        5.7   Promissory Note. Subject to the requirements of applicable state or Federal law or margin requirements, payment of all or
part of the purchase price of the Stock may be made by delivery of a full recourse promissory note ("Promissory Note"). The Promissory Note shall be executed by the optionee, made payable to the
Corporation and bear interest at such rate as the Committee shall determine, but in no case less than the minimum rate which will not cause under the Code (i) interest to be imputed,
(ii) original issue discount to exist, or (iii) any other similar results to occur. Unless otherwise determined by the Committee, interest on the Note shall be payable in quarterly
installments on March 31, June 30, September 30 and December 31 of each year. A Promissory Note shall contain such other terms and conditions as may be determined by the
Committee; provided, however, that the full principal amount of the Promissory Note and all unpaid interest accrued thereon shall be due not later than five years from the date of exercise. The
Corporation may obtain from the optionee a security interest in all shares of Stock issued to the optionee under the Plan for the purpose of securing payment under the Promissory Note and may retain
possession of the stock certificates representing such shares in order to perfect its security interest. 

        5.8   Rights as a Shareholder. An optionee or successor shall have no rights as a shareholder with respect to any Stock
underlying any option until the date of the issuance to such optionee of a certificate for such Stock. No adjustment shall be made for dividends (ordinary or extraordinary, whether in cash, securities
or other property) or distributions or other rights for which the record date is prior to the date such Stock certificate is issued, except as provided in Section 6. 

        5.9   Modification, Extension and Renewal of Options. Subject to the terms and conditions of the Plan, the Committee may
modify, extend or renew outstanding options granted under the Plan, or accept the surrender of outstanding options (to the extent not exercised) and authorize the granting of new options in
substitution therefor. 

        5.10 Vesting and Restrictions. The Committee shall have complete authority and discretion to set the terms, conditions,
restrictions, vesting schedules and other provisions of any option in the applicable Stock Option Agreement and shall have complete authority to require conditions and restrictions on any Stock issued
pursuant to this Plan; provided, however, that except with respect to options granted to officers or directors of the Corporation, options granted pursuant to this Plan shall be exercisable or "vest"
at the rate of at least 20% per year over the 5-year period beginning on the date the option is granted. Options granted to officers and directors shall become exercisable or "vest,"
subject to subject to the condition of continued employment and/or continued service on the Board of Directors, as appropriate. The maximum vesting period for options granted to officers or directors
will be ten years from the date of grant. 

        5.11 Other Provisions. The Stock Option Agreements shall contain such other provisions, including without limitation,
restrictions or conditions upon the exercise of options, as the Committee shall deem advisable. 

5

 

        6.     ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. 

        6.1   Subdivision or Consolidation. Subject to any required action by shareholders of the Corporation, the number of shares of
Stock covered by each outstanding option, and the exercise price thereof, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Stock of the Corporation
resulting from a subdivision or consolidation of shares, including, but not limited to, a stock split, reverse stock split, recapitalization, continuation or reclassification, or the payment of a
stock dividend (but only on the Stock) or any other increase or decrease in the number of such shares effected without receipt of consideration by the Corporation. Any fraction of a share subject to
option that would otherwise result from an adjustment pursuant to this Section shall be rounded downward to the next full number of shares without other compensation or consideration to the holder of
such option. 

        6.2   Capital Transactions. Upon a sale or exchange of all or substantially all of the assets of the Corporation, a merger or
consolidation in which the Corporation is not the surviving corporation, a merger, reorganization or consolidation in which the Corporation is the surviving corporation and shareholders of the
Corporation exchange their stock for securities or property, a liquidation of the Corporation, or similar transaction as determined by the Committee ("Capital Transaction"), this Plan and each option
issued under this Plan, whether vested or unvested, shall terminate, unless such options are assumed by a successor corporation in a merger or consolidation, immediately prior to such Capital
Transaction; provided, however, that unless the outstanding options are assumed by a successor corporation in a merger or consolidation, subject to terms approved by the Committee, all optionees will
have the right, during the 15 days prior to such Capital Transaction, to exercise all vested options. The Corporation shall, subject to any nondisclosure provisions, attempt to provide
optionees at least 15 days notice of the option termination date. The Committee may (but shall not be obligated to) (i) accelerate the vesting of any option or (ii) apply the
foregoing provisions, including but not limited to termination of this Plan and options granted pursuant to the Plan, in the event there is a sale of 51% or more of the stock of the Corporation in any
two year period or a transaction similar to a Capital Transaction. 

        6.3   Adjustments. To the extent that the foregoing adjustments relate to stock or securities of the Corporation, such
adjustments shall be made by the Committee, whose determination in that respect shall be final, binding and conclusive. 

        6.4   Ability to Adjust. The grant of an option pursuant to the Plan shall not affect in any way the right or power of the
Corporation to make adjustments, reclassifications, reorganizations or changes of its capital or business structure or to merge, consolidate, dissolve, liquidate, sell or transfer all or any part of
its business or assets. 

        6.5   Notice of Adjustment. Whenever the Corporation shall take any action resulting in any adjustment provided for in this
Section, the Corporation shall forthwith deliver notice of such action to each optionee, which notice shall set forth the number of shares subject to the option and the exercise price thereof
resulting from such adjustment. 

        6.6   Limitation on Adjustments. Any adjustment, assumption or substitution of an Incentive Option shall comply with
Section 425 of the Code, if applicable. 

        7.     NONASSIGNABILITY. Options granted under this Plan may not be sold, pledged, assigned or transferred in any manner other
than by will or by the laws of intestate succession, and may be exercised during the lifetime of an optionee only by such optionee. Any transfer in violation of this Section shall void such option,
and any Stock Option Agreement entered into by the optionee and the Corporation regarding such transferred option shall be void and have no further force or effect. No option shall be pledged or
hypothecated in any way, nor shall any option be subject to execution, attachment or similar process. 

6

 

        8.     NO RIGHT OF EMPLOYMENT. Neither the grant nor exercise of any option nor anything in this Plan shall impose upon the
Corporation or any other corporation any obligation to employ or continue to employ any optionee. The right of the Corporation and any other corporation to terminate any employee shall not be
diminished or affected because an option has been granted to such employee. 

        9.     TERM OF PLAN. This Plan is effective on the date the Plan is adopted by the Board of Directors and options may be granted
pursuant to the Plan from time to time within a period of ten (10) years from such date, or the date of any required shareholder approval required under the Plan, if earlier. Termination of the
Plan shall not affect any option theretofore granted. 

        10.   AMENDMENT OF THE PLAN. The Board of Directors of the Corporation may, subject to any required shareholder approval,
suspend, discontinue or terminate the Plan, or revise or amend it in any respect whatsoever with respect to any shares of Stock at that time not subject to options. 

        11.   APPLICATION OF FUNDS. The proceeds received by the Corporation from the sale of Stock pursuant to options may be used for
general corporate purposes. 

        12.   RESERVATION OF SHARES. The Corporation, during the term of this Plan, shall at all times reserve and keep available such
number of shares of Stock as shall be sufficient to satisfy the requirements of the Plan. 

        13.   NO OBLIGATION TO EXERCISE OPTION. The granting of an option shall not impose any obligation upon the optionee to exercise
such option. 

        14.   APPROVAL OF BOARD OF DIRECTORS AND SHAREHOLDERS. The Plan shall not take effect until approved by the Board of Directors
of the Corporation. This Plan shall be approved by a vote of the shareholders within 12 months from the date of approval by the Board of Directors. In the event such shareholder vote is not
obtained, all options granted hereunder, whether vested or unvested, shall be null and void. Further, any stock acquired pursuant to the exercise of any options under this Agreement may not count for
purposes of determining whether shareholder approval has been obtained. 

        15.   WITHHOLDING TAXES. Notwithstanding anything else to the contrary in this Plan or any Stock Option Agreement, the exercise
of any option shall be conditioned upon payment by such optionee in cash, or other provisions satisfactory to the Committee, of all local, state, federal or other withholding taxes applicable, in the
Committee's judgment, to the exercise or to later disposition of shares acquired upon exercise of an option. 

        16.   PARACHUTE PAYMENTS. Any outstanding option under the Plan may not be accelerated to the extent any such acceleration of
such option would, when added to the present value of other payments in the nature of compensation which becomes due and payable to the optionee would result in the payment to such optionee of an
excess parachute payment under Section 280G of the Code. The existence of any such excess parachute payment shall be determined in the sole and absolute discretion of the Committee. 

        17.   SECURITIES LAWS COMPLIANCE. Notwithstanding anything contained herein, the Corporation shall not be obligated to grant
any option under this Plan or to sell, issue or effect any transfer of any Stock unless such grant, sale, issuance or transfer is at such time effectively (i) registered or exempt from
registration under the Securities Act of 1933, as amended (the "Act"), and (ii) qualified or exempt from qualification under the California Corporate Securities Law of 1968 and any other
applicable state securities laws. As a condition to exercise of any option, each optionee shall make such representations as may be deemed appropriate by counsel to the Corporation for the Corporation
to use any available exemption from registration under the Act or qualification under any applicable state securities law. 

7

 

        18.   RESTRICTIVE LEGENDS. The certificates representing the Stock issued upon exercise of options granted pursuant to this
Plan will bear any legends required by applicable securities laws as determined by the Committee. 

        19.   NOTICES. Any notice to be given under the terms of the Plan shall be addressed to the Corporation in care of its
Secretary at its principal office, and any notice to be given to an optionee shall be addressed to such optionee at the address maintained by the Corporation for such person or at such other address
as the optionee may specify in writing to the Corporation. 

        20.   INFORMATION TO PARTICIPANTS. The Corporation shall make available to all holders of options the information required
pursuant to § 260.140.46 of the California Code of Regulations. 

        As
adopted by the Board of Directors on                        , 2002.

	Re:
	2002 Stock Option Plan

To
Whom It May Concern: 

        I
(the "Optionee") hereby exercise my right to purchase shares of common stock (the "Stock") of Mitek Systems, Inc., a Delaware corporation (the "Corporation"), pursuant to, and
