MITEK SYSTEMS, INC. NOTES TO FINANCIAL STATEMENTS-UNAUDITED 1. Basis of Presentation The accompanying unaudited financial statements of Mitek Systems, Inc. (the "Company") have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all information and footnote disclosures that are otherwise required by Regulation S-X and that will normally be made in the Company's Annual Report on Form 10-K. The financial statements do, however, reflect all adjustments (solely of a normal recurring nature) which are, in the opinion of management, necessary for a fair statement of the results of the interim periods presented. Results as of June 30, 2004 and for the three and nine months ended June 30, 2004 are not necessarily indicative of results which may be reported for any other interim period or for the year as a whole. Accounting Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates. The operations from Fiscal 2003 and the nine months ended June 30, 2004 have resulted in significant operating losses. The Company has managed its cash requirements for this period principally from cash generated from operations, though the last quarter saw the Company address its cash requirements by issuing Convertible Debt as discussed in Note 6 of the accompanying financial statements. Additionally, the Company reduced its expected future cash needs by entering into the agreement with Harland Financial Solutions whereby certain personnel and overhead expenses were assumed by Harland in the transactions discussed in Note 7 of the accompanying financial statements. Certain prior year's balances have been reclassified to conform to the 2003 presentation. 2. New Accounting Pronouncements In November 2002, the FASB issued FASB Interpretation No. 45, Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees. This Interpretation elaborates on the disclosures to be made by a guarantor in its interim and annual financial statements about its obligations under certain guarantees that it has issued. It also clarifies that a guarantor is required to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. This Interpretation does not prescribe a specific approach for subsequently measuring the guarantor's recognized liability over the term of the related guarantee. This Interpretation also incorporates, without change, the guidance in FASB Interpretation No. 34, Disclosure of Indirect Guarantees of Indebtedness of Others, which is being superseded. The initial recognition and measurement provisions of this Interpretation are applicable on a prospective basis to guarantees issued or modified after December 31, 2002, irrespective of the guarantor's fiscal year-end. The disclosure requirements in this Interpretation are effective for financial statements of interim or annual periods ending after December 15, 2002. The Company has issued no guarantees that qualify for disclosure in this interim financial statement. In December 2002, the FASB issued Statement of Financial Accounting Standards ("SFAS") No. 148 Accounting for Stock-Based Compensation - Transition and Disclosure. SFAS No. 148 amends SFAS No. 123, Accounting for Stock-Based Compensation, to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, SFAS No. 148 amends the disclosure requirements of SFAS No. 123 to require prominent disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. The amendments to SFAS No. 123 provided for under SFAS No. 148 are effective for financial statements for fiscal years ending after December 15, 2002. The 4

Company has not elected to adopt the fair value accounting provisions of SFAS No. 123 and therefore the adoption of SFAS No. 148 did not have a material effect on our results of operations or financial position. In January 2003, the FASB issued SFAS No. 150 Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity. SFAS 150 establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. It requires that an issuer classify a financial instrument that is within its scope as a liability (or an asset in some circumstances). This Statement is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003. The Company adopted the provisions of this Statement and it had no impact on its financial statements. In January 2003, the FASB issued Interpretation No. 46 (FIN 46), Consolidation of Variable Interest Entities. In general, a variable interest entity is a corporation, partnership, trust, or any other legal structure used for business purposes that either (a) does not have equity investors with voting rights or (b) has equity investors that do not provide sufficient financial resources for the entity to support its activities. FIN 46 requires a variable interest entity to be consolidated by a company if that company is subject to a majority of the risk of loss from the variable interest entity's activities or entitled to receive a majority of the entity's residual returns or both. The consolidation requirements of FIN 46 were initially to apply to variable interest entities created after January 31, 2003. The consolidation requirements were initially to apply to transactions entered into prior to February 1, 2003 in the first fiscal year or interim period beginning after June 15, 2003. The FASB postponed implementation of FIN 46 in December 2003. The Company has no variable interest entities. 3. Accounting for Stock-Based Compensation The Company accounts for stock-based compensation in accordance with Accounting Principles Board Opinion ("APB") No. 25, Accounting for Stock Issued to Employees, and FASB Interpretation No. 44, Accounting for Certain Transactions Involving Stock Compensation. Pro forma information regarding net loss and loss per share is required by SFAS No. 123, Accounting for Stock-based Compensation, and has been determined as if the Company had accounted for its employee stock options under the fair value method of that Statement. The fair value for these options was estimated at the dates of grant using the Black-Scholes option valuation model with the following weighted-average assumptions for the three months and nine months ended June 30, 2004 and 2003. 2004 2003 ---- ---- Risk free interest rates 2.6% 2.0% Dividend yields 0% 0% Volatility 77% 76% Weighted average expected life 3 years 3 years The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because the Company's employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management's opinion the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options. For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the options' vesting period. The Company's pro forma information is as follows (in thousands, except for net income/loss per share information): Three months ended Nine months ended June 30 June 30 ----------------------------------------------------------- 2004 2003 2004 2003 ---- ---- ---- ---- Net loss as reported $ (1,431) $ (953) $ (3,323) $ (867) Net loss pro forma (1,527) (968) (3,612) (1,507) Net loss per share as reported (.13) (.09) (.29) (.08) Net loss per share pro forma (.13) (.09) (.32) (.14) 5

4. Revolving Line of Credit In June 2004, the Company entered into a Convertible Note with Laurus Master Fund (Laurus). The principal amount of the note was $3,000,000. Laurus can convert any portion of the principal outstanding to common stock at a fixed price per share of $.70 (Conversion Price) any time the market price of the Company's common stock exceeds the Conversion Price by 10%. The note carries an interest rate of prime (as published in the Wall Street Journal) plus 1%, with monthly interest payments to be made by the Company. Principal repayments begin on December 1, 2004, and are ratable over a 36 month term. In connection with this transaction, the Company issued warrants to Laurus for the purchase of up to 860,000 shares of common stock at prices ranging from $0.79 to $0.92 per share. The Note is secured by a general lien on all assets of the Company, and as a condition of this transaction, the Company's line of Credit with First National Bank was cancelled. (Note 6) 5. Product Revenues - Below is a summary of the revenues by product lines. Three Months Ended Nine Months Ended June 30 June 30 REVENUE 2004 2003 2004 2003 ---- ---- ---- ---- (000'S) Recognition Toolkits $ 330 $ 453 $1,568 $ 4,071 Check Image Solutions 197 2,298 1,406 4,490 Document and Image Processing Solutions 65 40 420 611 Maintenance and other 395 251 1,306 699 ------------------------------------------------------------------ Total Revenue $ 987 $ 3,042 $4,700 $ 9,871 ================================================================== 6. Issuance of Convertible Debt In June 2004, the Company entered into a Convertible Note with Laurus Master Fund (Laurus). The principal amount of the note was $3,000,000. Laurus can convert any portion of the principal outstanding to common stock at a fixed price per share of $.70 (Conversion Price) any time the market price of the Company's common stock exceeds the Conversion Price by 10%. The note carries an interest rate of prime (as published in the Wall Street Journal) plus 1%, with monthly interest payments to be made by the Company. Principal repayments begin on December 1, 2004, and are ratable over a 36 month term. The Note is secured by a general lien on all assets of the Company, and as a condition of this transaction, the Company's line of Credit with First National Bank was cancelled. In connection with the Convertible Note, the Company issued warrants to Laurus to purchase 860,000 of common stock, at prices ranging from $.79 to $.92 and paid fees of $74,400. The fair value attributable to the warrants was $531,280, determined by the Black-Scholes valuation model. Additionally, the Company incurred legal and other costs amounting to $142,000 in connection with this transaction. These costs and the value attributable to the warrants are shown as an offset to the Convertible Note and will be amortized as interest expense over the term of the Note. At June 30, 2004, the unamortized amounts were $672,804. Because the note contains a contingent beneficial conversion feature, when such contingency is met and the note becomes convertible, the value of the beneficial conversion feature will be recorded by the Company. 6

7. Subsequent Events On July 7, 2004, the Company entered into an agreement with Harland Financial Solutions (HFS) wherein HFS acquired certain of the Company's trade assets relating to its Item Processing line of business. In addition, HFS assumed the trade liabilities and hired certain of the Company's personnel relating to this line of business. In connection with this transaction, the Company entered into a reseller agreement wherein HFS will be the exclusive reseller of this line of business. The consideration for this transaction was $1,425,000, plus the assumption of liabilities. Under the agreement with HFS, the Company may receive additional consideration from HFS should certain contractual issues be resolved, but no assurance can be made this will occur. 8. Net Liabilities Held for Sale Certain assets and Liabilities of the Company's CheckQuest product line have been classified as held for sale at June 30, 2004. The Components of these net liabilities at June 30, 2004 are as follows: Accounts Payable $ 6,916 Deferred Revenue 940,213 Customer Deposits 40,198 Other Liabilities 688 Accounts Receivable -453,436 Fixed Assets (Net of Accumulated Depreciation) -91,187 Prepaid Licenses -60,938 Other Assets -5,938 ------------ Net Liabilities $ 376,516 ============ 7

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Management's Discussion In addition to historical information, this Management's Discussion and Analysis of Financial Condition and Results of Operations (the "MD&A") contains certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. As contained herein, the words "expects," "anticipates," "believes," "intends," "will," and similar types of expressions identify forward-looking statements, which are based on information that is currently available to the Company, speak only as of the date hereof, and are subject to certain risks and uncertainties. To the extent that the MD&A contains forward-looking statements regarding the financial condition, operating results, business prospects or any other aspect of the Company, please be advised that the Company's actual financial condition, operating results and business performance may differ materially from that projected or estimated by the Company in forward-looking statements. The Company has attempted to identify certain of the factors that it currently believes may cause actual future experiences and results to differ from the Company's current expectations. The difference may be caused by a variety of factors, including, but not limited, to the following: (i) adverse economic conditions; (ii) decreases in demand for Company products and services; (iii) intense competition, including entry of new competitors into the Company's markets; (iv) increased or adverse federal, state and local government regulation; (v) the Company's inability to retain or renew its working capital credit line or otherwise obtain additional capital on terms satisfactory to the Company; (vi) increased or unexpected expenses; (vii) lower revenues and net income than forecast; (viii) price increases for supplies; (ix) inability to raise prices; (x) the risk of additional litigation and/or administrative proceedings involving the Company and its employees; (xi) higher than anticipated labor costs; (xii) adverse publicity or news coverage regarding the Company; (xiii) inability to successfully carry out marketing and sales plans, including the Company's strategic realignment; (xiv) loss of key executives; (xv) changes in interest rates; (xvi) inflationary factors; (xvii) and other specific risks that may be alluded to in this MD&A. The Company's strategy for fiscal 2004 is to grow the identified markets for its new products and enhance the functionality and marketability of the Company's character recognition technology. In particular, Mitek is determined to expand the installed base of its Recognition Toolkits and leverage existing technology by devising recognition-based applications to detect potential fraud and loss at financial institutions. The Company also seeks to penetrate additional markets for its Document and Image Processing Solutions by taking advantage of specific vertical applications which lend themselves to this type of labor-saving technology. The Company has also taken steps to generate working capital, including in June entering into a $3,000,000 promissory note with Laurus Master Fund, Ltd and in July divesting to Harland Financial Solutions ("HFS") certain assets and liabilities associated with the Company's Item Processing line of business and entering into an exclusive reselling relationship with HFS for the Item Processing line of business. The arrangement with HFS generated working capital, while at the same time reduced ongoing personnel and overhead expenses. Management presumes that users of these interim financial statements and information have read or have access to the discussion and analysis for the preceding fiscal year. See also Item 3, "Quantitative and Qualitative Disclosures about Market Risk." CRITICAL ACCOUNTING POLICIES Revenue Recognition The Company enters into contractual arrangements with end users that may include licensing of the Company's software products, product support and maintenance services, consulting services, resale of third-party hardware, or various combinations thereof, including the sale of such products or services separately. The Company's accounting policies regarding the recognition of revenue for these contractual arrangements is fully described in Notes to the Audited Financial Statements for the year ended September 30, 2003 included in the Company's Form 10-K. 8

The Company considers many factors when applying accounting principles generally accepted in the United States of America related to revenue recognition. These factors include, but are not limited to: o The actual contractual terms, such as payment terms, delivery dates, and pricing of the various product and service elements of a contract o Availability of products to be delivered o Time period over which services are to be performed o Creditworthiness of the customer o The complexity of customizations to the Company's software required by service contracts o The sales channel through which the sale is made (direct, VAR, distributor, etc.) o Discounts given for each element of a contract o Any commitments made as to installation or implementation "go live" dates Each of the relevant factors is analyzed to determine its impact, individually and collectively with other factors, on the revenue to be recognized for any particular contract with a customer. Management is required to make judgments regarding the significance of each factor in applying the revenue recognition standards, as well as whether or not each factor complies with such standards. Any misjudgment or error by management in its evaluation of the factors and the application of the standards, especially with respect to complex or new types of transactions, could have a material adverse affect on the Company's future revenues and operating results. Accounts Receivable. We evaluate the creditworthiness of our customers prior to order fulfillment and we perform ongoing credit evaluations of our customers to adjust credit limits based on payment history and our assessment of the customer's current creditworthiness. We constantly monitor collections from our customers and maintain a provision for estimated credit losses that is based on historical experience and on specific customer collection issues. While such credit losses have historically been within our expectations and the provisions established, we cannot guarantee that we will continue to experience the same credit loss rates that we have in the past. Since our revenue recognition policy requires customers to be deemed creditworthy, our accounts receivable are based on customers whose payment is reasonably assured. Our accounts receivable are derived from sales to a wide variety of customers. We do not believe a change in liquidity of any one customer or our inability to collect from any one customer would have a material adverse impact on our financial position. Deferred Income Taxes. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. We maintain a valuation allowance against the deferred tax asset due to uncertainty regarding the future realization based on historical taxable income, projected future taxable income, and the expected timing of the reversals of existing temporary differences. Until such time as the Company can demonstrate that it will no longer incur losses or if the Company is unable to generate sufficient future taxable income we could be required to maintain the valuation allowance against our deferred tax assets. ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS: Comparison of Three Months and Nine Months Ended June 30, 2004 and 2003 Net Sales. Net sales for the three-month period ended June 30, 2004 were $987,000, compared to $3,042,000 for the same period in 2003, a decrease of $2,055,000, or 68%. The decrease was primarily attributable to a 91% decrease in revenue from Check Image Solutions. The Company continued to experience delayed purchasing decisions, which we believe are due to continued customer hesitancy to adopt check imaging solutions. Though image acceptance is mandated by the passage of Check 21, imaging standards required under this legislation are not yet final. The Company also experienced substantial purchasing hesitancy from customers who expressed concern over the Company's recent quarterly losses and the delisting of the Company's stock from NASDAQ. Subsequent to the quarter ended June 30, 2004, the Company substantially exited this line of business, by agreeing to the transaction with Harland Financial Solutions described in Note 7 9

of the accompanying financial statements. The Company also experienced a 27% decline in revenue associated with our recognition toolkits, the result of continued customer concern over the Company's recent quarterly losses, and enterprise licenses signed during fiscal 2003 which will not renew until later in fiscal 2004. Sales in the Document and Image Processing Solutions increased by 63%, primarily due to orders from two key resellers. Sales of Maintenance rose by 57%, reflecting the Company's efforts to contact current and past customers to encourage the renewal of product support contracts. This has resulted in an increase in the installed base of customers purchasing product support. Net sales for the nine-month period ended June 30, 2004 were $4,700,000, compared to $9,871,000 for the same period in 2003, a decrease of $5,171,000 or 52%. The decrease was primarily attributable to a 69% decrease in revenue from Check Image Solutions. The Company continued to experience delayed purchasing decisions, which we believe are due to continued customer hesitancy to adopt check imaging solutions. Though image acceptance is mandated by the passage of Check 21, imaging standards required under this legislation are not yet final. The Company also experienced substantial purchasing hesitancy from customers who expressed concern over the Company's recent quarterly losses and the delisting of the Company's stock from NASDAQ. Subsequent to the quarter ended June 30, 2004, the Company substantially exited this line of business, by agreeing to the transaction with Harland Financial Solutions described in Note 7 of the accompanying financial statements. The Company also experienced a 61% decline in revenue associated with our recognition toolkits, the result of continued customer concern over the Company's recent quarterly losses, and enterprise licenses signed during fiscal 2003 which will not renew until later in fiscal 2004. Sales in the Document and Image Processing Solutions decreased by 31%. This is primarily due to the absence of a dedicated sales force for this product line, which the Company intends to put into place later during the 2004 fiscal year. Sales of Maintenance rose by 87%, reflecting the Company's efforts to contact current and past customers to encourage the renewal of product support contracts. This has resulted in an increase in the installed base of customers purchasing product support. Cost of Sales. Cost of sales for the three-month period ended June 30, 2004 was $371,000, compared to $1,392,000 for the same period in 2003, a decrease of $1,021,000 or 73%. Stated as a percentage of net sales, cost of sales decreased to 38% for the three-month period ended June 30, 2004 compared to 46% for the same period in 2003. The dollar decrease in cost of sales is almost entirely due to reduced hardware installations related to the Company's Checkquest product line, which typically carry higher costs, during the quarter, as compared to the same quarter in 2003. The decrease as a percentage of net sales is due to the product mix shifting from hardware installations to the Company's software product lines, which typically carry higher margins. Cost of sales for the nine-month period ended June 30, 2004 was $1,893,000, compared to $3,499,000 for the same period in 2003, a decrease of $1,606,000 or 46%. Stated as a percentage of net sales, cost of sales increased to 40% for the nine-month period ended June 30, 2004, compared to 35% for the same period in 2003. The dollar decrease in cost of sales is almost entirely due to reduced hardware installations related to the Company's Checkquest product line, which typically carry higher costs. The increase as a percentage of net sales is due to the product mix of software sold shifting toward the Company's Checkscript and QuickStrokes Premier Banking Edition products, each of which carries a royalty. Operations Expenses. Operations expenses include costs associated with shipping and receiving, quality assurance, customer support, installation and training. As installation, training, maintenance and customer support revenues are recognized, an appropriate amount of these costs are charged to cost of sales, with unabsorbed costs remaining in operations expense. Gross Operations expenses for the three-month period ended June 30, 2004 were $454,000, compared to $583,000 for the same period in 2003, a decrease of $129,000 or 22%. Net Operations expenses for the three-month period ended June 30, 2004 were $326,000, compared to $432,000 for the same period in 2003, a decrease of $106,000 or 25%. Stated as a percentage of net sales, operations expenses were 33% for the three-month period ended June 30, 2003, as compared with 14% for the same period in 2003. The dollar decrease in gross expenses is primarily attributable to reduced amount of salaries and wages, due to a reassignment of personnel into sales functions. The dollar decrease in net expense is attributable to the reduced spending discussed above. The increase in expenses as a percentage of net sales is primarily attributable to lower revenues. Gross Operations expenses for the nine-month period ended June 30, 2004 were $1,458,000, compared to $1,717,000 for the same period in 2003, a decrease of $259,000 or 15%. Net Operations expenses for the nine-month period ended June 30, 2004 were $1,065,000, compared to $1,292,000 for the same period in 2003, a 10

decrease of $227,000 or 18%. Stated as a percentage of net sales, operations expenses increased to 23% for the nine-month period ended June 30, 2004, compared to 13% for the same period in 2003. The dollar decrease in gross expenses is primarily attributable to reduced amount of salaries and wages, due to a reassignment of personnel into sales functions. The dollar decrease in net expense is attributable to the reduced spending discussed above. The increase in expenses as a percentage of net sales is primarily attributable to lower revenues. Selling and Marketing Expenses. Selling and marketing expenses for the three-month period ended June 30, 2004 were $450,000, compared to $1,101,000 for the same period in 2003, a decrease of $651,000 or 59%. Stated as a percentage of net sales, selling and marketing expenses increased to 46% for the three-month period ended June 30, 2004, as compared with 36% for the same period in 2003. The dollar decrease in expenses is primarily attributable to reduced commissions resulting from lower sales, as well as reduced salaries expense, as the Company reduced its direct sales force in the check image solution product line. The Company believes this product line is better suited to an indirect sales channel, and the Company has signed two resellers to representation agreements to move in this direction. Selling and marketing expenses for the nine-month period ended June 30, 2004 were $1,572,000, compared to $2,908,000 for the same period in 2003, a decrease of $1,336,000 or 46%. Stated as a percentage of net sales, selling and marketing expenses increased to 33% from 29% for the same period in 2003. The dollar decrease in expenses is primarily attributable to reduced commissions resulting from lower sales, as well as reduced salaries expense, as the Company reduced its direct sales force in the check image solution product line. The Company believes this product is better suited to an indirect sales channel, and the Company has signed two resellers to representation agreements to move in this direction. The increase as a percentage of net sales is primarily attributable to reduced sales. Research and Development Expenses. Research and development expenses are incurred to maintain existing products, develop new products or new product features, technical customer support, and development of custom projects. Research and development expenses for the three-month period ended June 30, 2004 were $644,000, compared to $556,000 for the same period in 2003, an increase of $88,000 or 16%. Stated as a percentage of net sales, research and development expenses increased to 65% for the three-month period ended June 30, 2004, compared to 18% for the same period in 2003. The dollar increase in expenses is the result of consultants engaged to complete two engineering projects. The increase as a percentage of net sales for the three-month period is primarily attributable to the decrease in sales. Research and development expenses for the nine-month period ended June 30, 2004 were $1,812,000, compared to $1,680,000 for the same period in 2003, an increase of $132,000 or 8%. Stated as a percentage of net sales, research and development expenses increased to 39% for the nine-month period ended June 30, 2004, compared to 17% for the same period in 2003. The dollar increase in expenses is the result of consultants engaged to complete two engineering projects, offset by the prior quarters' reclassification of costs. Such costs, amounting to $92,000 were reclassified as costs of goods sold, and served to reduce research and development expense during the first quarter. The increase as a percentage of net sales for the three-month period is primarily attributable to the decrease in sales. General and Administrative Expenses. General and administrative expenses for the three-month period ended June 30, 2004 were $614,000, compared to $517,000 for the same period in 2003, an increase of $97,000 or 19%. Stated as a percentage of net sales, general and administrative expenses increased to 62% for the three-month period ended June 30, 2004, compared to 17% for the same period in 2003. The dollar increase in expenses for the three month period is attributable to $20,000 of additional salaries expense, as the President and Chief Executive Officer was not a separate position in 2003 and $145,000 in 11

increased legal costs primarily relating to analysis of strategic alternatives, including potential mergers, capital infusions, and other strategic alternatives. The increase in expenses as a percentage of net sales is primarily attributable to lower revenues. General and administrative expenses for the nine-month period ended June 30, 2004 were $1,674,000, compared to $1,356,000 for the same period in 2003, an increase of $318,000 or 23%. Stated as a percentage of net sales, general and administrative expenses increased to 36% for the nine-month period ended June 30, 2004, compared to 14% for the same period in 2003. The dollar increase in expenses for the three month period is attributable to $120,000 of additional salaries expense, as the President and Chief Executive Officer was not a separate position in 2003 and $215,000 in increased legal costs primarily relating to analysis of strategic alternatives, including potential mergers, capital infusions, and other strategic alternatives. The increase in expenses as a percentage of net sales is primarily attributable to lower revenues. Interest and Other Income (Expense) - Net. Interest and other income (expense) for the three-month period ended June 30, 2004 was ($13,000), compared to $4,000 for the same period in 2003, a decrease of $17,000. Interest and other income (expense) for the nine-month period ended June 31, 2004 was ($6,000), compared to $8,000 for the same period in 2003, a decrease of $12,000. The decrease in net interest and other income (expense) for the period ended June 30, 2004 is primarily the result of the Company's share of the net income from the Company's affiliate, Mitek Systems, Ltd. LIQUIDITY AND CAPITAL At June 30, 2004 the Company had $2,719,000 in cash as compared to $1,819,000 at September 30, 2003. Accounts receivable totaled $1,440,000, a decrease of $1,461,000 over the September 30, 2003, balance of $2,901,000. The Company has financed its cash needs during the third quarter of fiscal 2004 primarily from collection of accounts receivable and the proceeds from its convertible debt financing with Laurus. The Company financed its cash needs during fiscal 2003 primarily from collection of accounts receivable. Net cash used by operating activities during the nine months ended June 30, 2004 was ($2,634,000). The primary use of cash from operating activities was the operating loss of ($3,324,000), a decrease in accounts payable of ($404,000), and a decrease in the accrued payroll and related taxes of ($153,000). The primary source of cash from operating activities was a decrease in accounts receivable of $1,389,000 and depreciation and amortization of $341,000. The Company used part of the cash provided from operating activities to finance the acquisition of equipment used in its business. During the nine months ended June 30, 2004, the Company also received cash of approximately $204,000 from financing activities in the form of proceeds from the exercise of stock options by employees and directors. The Company's working capital and current ratio were $2,195,000 and 1.75, respectively, at June 30, 2004, and $2,341,000 and 1.87, respectively, at September 30, 2003. At June 30, 2004, total liabilities to equity ratio was - -1087.08 to 1 compared to 1.19 to 1 at September 30, 2003. As of June 30, 2004, total liabilities were increased by $2,201,000 as compared to September 30, 2003. In June 2004, the Company entered into a Convertible Note with Laurus Master Fund (Laurus). The principal amount of the note was $3,000,000. Laurus can convert any portion of the principal outstanding to common stock at a fixed price per share of $.70 (Conversion Price) any time the market price of the Company's common stock exceeds the Conversion Price by 10%. The note carries an interest rate of prime (as published in the Wall Street Journal) plus 1%, with monthly interest payments to be made by the Company. Principal repayments begin on December 1, 2004, and are ratable over a 36 month term. The Note is secured by a general lien on all assets of the Company, and as a condition of this transaction, the Company's line of Credit with First National Bank was cancelled. See Part II Other Information - Item 2. Changes in Securities and Use of Proceeds. There are no significant capital expenditures planned for the foreseeable future. The Company evaluates its cash requirements on a quarterly basis. Historically, the Company has managed its cash requirements principally from cash generated from operations, though the last quarter saw the Company address its cash requirements by issuing Convertible Debt. Additionally, the Company reduced its expected future cash needs by entering into the agreement with Harland Financial Solutions whereby certain personnel and overhead expenses were assumed by Harland. Although the Company's strategy for fiscal 2004 is to grow the identified markets for its new products and enhance the functionality and marketability of the Company's character recognition technology, it has not yet 12

observed a significant change in liquidity or future cash requirements as a result of this strategy. Cash requirements over the next twelve months are principally to fund operations, including spending on research and development. The Company believes it has sufficient cash on hand and will generate sufficient cash from operations to meet its requirements for the next 12 months. New Accounting Pronouncements In November 2002, the FASB issued FASB Interpretation No. 45, Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees. This Interpretation elaborates on the disclosures to be made by a guarantor in its interim and annual financial statements about its obligations under certain guarantees that it has issued. It also clarifies that a guarantor is required to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken in issuing the guarantee. This Interpretation does not prescribe a specific approach for subsequently measuring the guarantor's recognized liability over the term of the related guarantee. This Interpretation also incorporates, without change, the guidance in FASB Interpretation No. 34, Disclosure of Indirect Guarantees of Indebtedness of Others, which is being superseded. The initial recognition and measurement provisions of this Interpretation are applicable on a prospective basis to guarantees issued or modified after December 31, 2002, irrespective of the guarantor's fiscal year-end. The disclosure requirements in this Interpretation are effective for financial statements of interim or annual periods ending after December 15, 2002. The Company has issued no guarantees that qualify for disclosure in this interim financial statement. In December 2002, the FASB issued Statement of Financial Accounting Standards ("SFAS") No. 148 Accounting for Stock-Based Compensation - Transition and Disclosure. SFAS No. 148 amends SFAS No. 123, Accounting for Stock-Based Compensation, to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, SFAS No. 148 amends the disclosure requirements of SFAS No. 123 to require prominent disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. The amendments to SFAS No. 123 provided for under SFAS No. 148 are effective for financial statements for fiscal years ending after December 15, 2002. The Company has not elected to adopt the fair value accounting provisions of SFAS No. 123 and therefore the adoption of SFAS No. 148 did not have a material effect on our results of operations or financial position. In January 2003, the FASB issued SFAS No. 150 Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity. SFAS 150 establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. It requires that an issuer classify a financial instrument that is within its scope as a liability (or an asset in some circumstances). This Statement is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003. The Company adopted the provisions of this Statement and it had no impact on its financial statements. In January 2003, the FASB issued Interpretation No. 46 (FIN 46), Consolidation of Variable Interest Entities. In general, a variable interest entity is a corporation, partnership, trust, or any other legal structure used for business purposes that either (a) does not have equity investors with voting rights or (b) has equity investors that do not provide sufficient financial resources for the entity to support its activities. FIN 46 requires a variable interest entity to be consolidated by a company if that company is subject to a majority of the risk of loss from the variable interest entity's activities or entitled to receive a majority of the entity's residual returns or both. The consolidation requirements of FIN 46 were initially to apply to variable interest entities created after January 31, 2003. The consolidation requirements were initially to apply to transactions entered into prior to February 1, 2003 in the first fiscal year or interim period beginning after June 15, 2003. The FASB postponed implementation of FIN 46 in December 2003. The Company has no variable interest entities. ITEM 3 QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK The Company is exposed to certain market risks arising from adverse changes in interest rates, primarily due to the potential effect of such changes on the Company's variable rate Convertible Note, as described under "Management's Discussion and Analysis of Financial Condition and Results of 13

Operations--Liquidity and Capital." The Company does not use interest rate derivative instruments to manage exposure to interest rate changes. ITEM 4. CONTROLS AND PROCEDURES The Company carried out an evaluation, under the supervision and with the participation of our management, including Mr. DeBello, the Company's President and Chief Executive Officer and Mr. Thornton, the Company's Chairman of the Board and Chief Financial Officer, of the effectiveness of the design and operation of the Company's disclosure controls and procedures pursuant to Exchange Act Rule 13a-14 as of the end of the period covered by this Quarterly Report on Form 10-Q. Based upon that evaluation, Mr. DeBello and Mr. Thornton concluded that the Company's disclosure controls and procedures are effective in timely alerting them to material information relating to the Company required to be included in the Company's periodic filings with the Securities and Exchange Commission. There was no change in the Company's internal control over financial reporting that occurred during the fiscal quarter covered by this Quarterly Report likely to materially affect our internal control over financial reporting. PART II - OTHER INFORMATION ITEM 2. - CHANGES IN SECURITIES AND USE OF PROCEEDS In June 2004, we issued to Laurus Master Fund, Ltd. a $3.0 million secured convertible promissory note with a term of three years, along with a warrant which is exercisable at any time through June 11, 2011, to purchase up to 860,000 shares of common stock at an exercise price of (i) $0.79 for the first 230,000 shares acquired thereunder; (ii) $0.85 for the next 230,000 shares acquired thereunder; and (iii) $0.92 for the remaining shares acquired thereunder. The note is convertible into approximately 4,285,714 shares of our common stock at an initial conversion price of $.70 per share, without taking into account additional shares which may be issuable upon conversion of interest paid on the note. The conversion price is subject to certain anti-dilution adjustments, including if we issue convertible or equity securities (subject to certain exceptions) at a price less than the conversion price. The proceeds from the promissory note will be used for working capital. As part of the issuance of the convertible promissory note, we granted to Laurus a blanket security interest in all of our assets. In the event we default in payment on the debt, or any other event of default occurs under the investment documents, 130% of the outstanding principal amount of the note and accrued interest will accelerate and be due and payable in full. We have agreed to register with the SEC for resale the shares of common stock that are issuable upon conversion of the note and upon exercise of the warrant, prior to September 9, 2004. The note and warrant were offered and sold in reliance on the exemption from registration provided by Rule 506 of Regulation D under the Securities Act. At closing, we paid a closing payment of $121,000 to Laurus Capital Management, LLC, manager of Laurus Master Fund, Ltd. and additional fees of approximately $30,000. ITEM 6.

In the event that Purchaser has properly declared an event of default with respect to this Agreement or any of the Related Agreements, then all loss recoveries received by Purchaser upon any such insurance thereafter may be applied to the obligations of the Company hereunder and under the Related Agreements, in such order as the Purchaser may determine.

The Company agrees to indemnify, hold harmless, reimburse and defend Purchaser, each of Purchaser's officers, directors, agents, affiliates, control persons, and principal shareholders, against any claim, cost, expense, liability, obligation, loss or damage (including reasonable legal fees) of any nature, incurred by or imposed upon the Purchaser which results, arises out of or is based upon: (i) any misrepresentation by Company or breach of any warranty by Company in this Agreement, any Related Agreement or in any exhibits or schedules attached hereto or thereto; or (ii) any breach or default in performance by Company of any covenant or undertaking to be performed by Company hereunder, or any other agreement entered into by the Company and Purchaser relating hereto. 8.2 Purchaser's Indemnification.

Conversion of Convertible Note. 9.1 Mechanics of Conversion. 21

(a) Provided the Purchaser has notified the Company of the Purchaser's intention to sell the Note Shares and the Note Shares are included in an effective registration statement or are otherwise exempt from registration when sold: (i) Upon the conversion of the Note or part thereof, the Company shall, at its own cost and expense, take all necessary action (including the issuance of an opinion of counsel reasonably acceptable to the Purchaser following a request by the Purchaser) to assure that the Company's transfer agent shall issue shares of the Company's Common Stock in the name of the Purchaser (or its nominee in compliance with applicable securities law) or such other persons as designated by the Purchaser in accordance with Section 9.1(b) hereof and in such denominations to be specified representing the number of Note Shares issuable upon such conversion; and (ii) The Company warrants that no instructions other than these instructions have been or will be given to the transfer agent of the Company's Common Stock and that after the Effectiveness Date (as defined in the Registration Rights Agreement) the Note Shares issued will be transferable subject to the prospectus delivery requirements of the Securities Act and the provisions of this Agreement. (b) Purchaser will give notice of its decision to exercise its right to convert the Note or part thereof by telecopying or otherwise delivering an executed and completed notice of the number of shares to be converted to the Company (the "Notice of Conversion"). The Purchaser will not be required to surrender the Note until the Purchaser receives a credit to the account of the Purchaser's prime broker through the DWAC system (as defined below), representing the Note Shares or until the Note has been fully satisfied. Each date on which a Notice of Conversion is telecopied or delivered to the Company in accordance with the provisions hereof shall be deemed a "Conversion Date." Pursuant to the terms of the Notice of Conversion, the Company will issue instructions to the transfer agent accompanied by an opinion of counsel within one (1) business day of the date of the delivery to the Company of the Notice of Conversion and shall cause the transfer agent to transmit the certificates representing the Conversion Shares to the Holder by crediting the account of the Purchaser's prime broker with the Depository Trust Company ("DTC") through its Deposit Withdrawal Agent Commission ("DWAC") system within three (3) business days after receipt by the Company of the Notice of Conversion (the "Delivery Date"). (c) The Company understands that a delay in the delivery of the Note Shares in the form required pursuant to Section 9 hereof beyond the Delivery Date could result in economic loss to the Purchaser. In the event that the Company fails to direct its transfer agent to deliver the Note Shares to the Purchaser via the DWAC system within the time frame set forth in Section 9.1(b) above and the Note Shares are not delivered to the Purchaser by the Delivery Date, as compensation to the Purchaser for such loss, the Company agrees to pay late payments to the Purchaser for late issuance of the Note Shares in the form required pursuant to Section 9 hereof upon conversion of the Note in the amount equal to the greater of: (i) $500 per business day after the Delivery Date; or (ii) the Purchaser's actual damages from such delayed delivery. Notwithstanding the foregoing, the Company will not owe the Purchaser any late payments if the delay in the delivery of the Note Shares beyond the Delivery Date is solely out of the control of the Company and the Company is actively trying to cure the cause of the delay. The Company shall pay any payments incurred under this Section in immediately available funds upon demand and, in the case of actual damages, accompanied by reasonable documentation of the amount of such damages. Such documentation shall show the number of shares of Common Stock the Purchaser is forced to purchase (in an open market transaction) which the Purchaser 22

anticipated receiving upon such conversion, and shall be calculated as the amount by which (A) the Purchaser's total purchase price (including customary brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (B) the aggregate principal and/or interest amount of the Note, for which such Conversion Notice was not timely honored. Nothing contained herein or in any document referred to herein or delivered in connection herewith shall be deemed to establish or require the payment of a rate of interest or other charges in excess of the maximum permitted by applicable law. In the event that the rate of interest or dividends required to be paid or other charges hereunder exceed the maximum amount permitted by such law, any payments in excess of such maximum shall be credited against amounts owed by the Company to a Purchaser and thus refunded to the Company. 10. Registration Rights. 10.1 Registration Rights Granted. The Company hereby grants registration rights to the Purchaser pursuant to a Registration Rights Agreement dated as of even date herewith between the Company and the Purchaser. 10.2 Offering Restrictions. Except as previously disclosed in the SEC Reports or in the Exchange Act Filings, or stock or stock options granted to employees or directors of the Company (these exceptions hereinafter referred to as the "Excepted Issuances"), the Company will not issue any securities with a continuously variable/floating conversion feature which are or could be (by conversion or registration) free-trading securities (i.e. common stock subject to a registration statement) prior to the full repayment or conversion of the Note (together with all accrued and unpaid interest and fees related thereto (the "Exclusion Period"). 11. Miscellaneous. 11.1 Governing Law. THIS AGREEMENT AND EACH RELATED AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS. ANY ACTION BROUGHT BY EITHER PARTY AGAINST THE OTHER CONCERNING THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT AND EACH RELATED AGREEMENT SHALL BE BROUGHT ONLY IN THE STATE COURTS OF NEW YORK OR IN THE FEDERAL COURTS LOCATED IN THE STATE OF NEW YORK. BOTH PARTIES AND THE INDIVIDUALS EXECUTING THIS AGREEMENT AND THE RELATED AGREEMENTS ON BEHALF OF THE COMPANY AGREE TO SUBMIT TO THE JURISDICTION OF SUCH COURTS AND WAIVE TRIAL BY JURY. IN THE EVENT THAT ANY PROVISION OF THIS AGREEMENT OR ANY RELATED AGREEMENT DELIVERED IN CONNECTION HEREWITH IS INVALID OR UNENFORCEABLE UNDER ANY APPLICABLE STATUTE OR RULE OF LAW, THEN SUCH PROVISION SHALL BE DEEMED INOPERATIVE TO THE EXTENT THAT IT MAY CONFLICT THEREWITH AND SHALL BE DEEMED MODIFIED TO CONFORM WITH SUCH STATUTE OR RULE OF LAW. ANY SUCH PROVISION WHICH MAY PROVE INVALID OR UNENFORCEABLE UNDER ANY LAW SHALL NOT AFFECT THE VALIDITY OR ENFORCEABILITY OF ANY OTHER PROVISION OF THIS AGREEMENT OR ANY RELATED AGREEMENT. 23

It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement or the Related Agreements, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring.

Procedure for Exercise. Delivery of Stock Certificates, Etc., on Exercise. The Company agrees that the shares of Common Stock purchased upon exercise of this Warrant shall be deemed to be issued to the Holder as the record owner of such shares as of the close of business on the date on which this Warrant shall have been surrendered and payment made for such shares in accordance herewith. As soon as practicable after the exercise of this Warrant in full or in part, and in any event within three (3) business days thereafter, the Company at its expense (including the payment by it of any applicable issue taxes) will cause to be issued in the name of and delivered to the Holder, or as such Holder (upon payment by such Holder of any applicable transfer taxes) may direct in compliance with applicable securities laws, a certificate or certificates for the number of duly and validly issued, fully paid and nonassessable shares of Common Stock (or Other Securities) to which such Holder shall be entitled on such exercise, plus, in lieu of any fractional share to which such holder would otherwise be entitled, cash equal to such fraction multiplied by the then Fair Market Value of one full share, together with any other stock or other securities and property (including cash, where applicable) to which such Holder is entitled upon such exercise pursuant to Section 1 or otherwise. Exercise. Payment may be made either (i) in cash or by certified or official bank check payable to the order of the Company equal to the applicable aggregate Exercise Price, (ii) by delivery of the Warrant, or shares of Common Stock and/or Common Stock receivable upon exercise of the Warrant in accordance with Section (b) below, or (iii) by a combination of any of the foregoing methods, for the number of Common Shares specified in such Exercise Notice (as such exercise number shall be adjusted to reflect any adjustment in the total number of shares of Common Stock issuable to the Holder per the terms of this Warrant) and the Holder shall thereupon be entitled to receive the number of duly authorized, validly issued, fully-paid and non-assessable shares of Common Stock (or Other Securities) determined as provided herein. Notwithstanding any provisions herein to the contrary, if the Fair Market Value of one share of Common Stock is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of exercising this Warrant for cash, the Holder may elect to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof being exercised) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Exercise Notice in which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula: X = Y (A-B) -------- A Where X = the number of shares of Common Stock to be issued to the Holder Y = the number of shares of Common Stock purchasable under the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being exercised (at the date of such calculation) A = the Fair Market Value of one share of the Company's Common Stock (at the date of such calculation) B = Exercise Price (as adjusted to the date of such calculation) Effect of Reorganization, Etc.; Adjustment of Exercise Price. Reorganization, Consolidation, Merger, Etc. In case at any time or from time to time, the Company shall (a) effect a reorganization, (b) consolidate with or merge into any other person, or (c) transfer all or substantially all of its properties or assets to any other person under any plan or arrangement contemplating the dissolution of the Company, then, in each such case, as a condition to the consummation of such a transaction, proper and 3

adequate provision shall be made by the Company whereby the Holder of this Warrant, on the exercise hereof as provided in Section 1 at any time after the consummation of such reorganization, consolidation or merger or the effective date of such dissolution, as the case may be, shall receive, in lieu of the Common Stock (or Other Securities) issuable on such exercise prior to such consummation or such effective date, the stock and other securities and property (including cash) to which such Holder would have been entitled upon such consummation or in connection with such dissolution, as the case may be, if such Holder had so exercised this Warrant, immediately prior thereto, all subject to further adjustment thereafter as provided in Section 4. Dissolution. In the event of any dissolution of the Company following the transfer of all or substantially all of its properties or assets, the Company, concurrently with any distributions made to holders of its Common Stock, shall at its expense deliver or cause to be delivered to the Holder the stock and other securities and property (including cash, where applicable) receivable by the Holder of the Warrant pursuant to Section 3.1, or, if the Holder shall so instruct the Company, to a bank or trust company specified by the Holder and having its principal office in New York, NY as trustee for the Holder of the Warrant (the "Trustee"). Continuation of Terms. Upon any reorganization, consolidation, merger or transfer (and any dissolution following any transfer) referred to in this Section 3, this Warrant shall continue in full force and effect and the terms hereof shall be applicable to the shares of stock and other securities and property receivable on the exercise of this Warrant after the consummation of such reorganization, consolidation or merger or the effective date of dissolution following any such transfer, as the case may be, and shall be binding upon the issuer of any such stock or other securities, including, in the case of any such transfer, the person acquiring all or substantially all of the properties or assets of the Company, whether or not such person shall have expressly assumed the terms of this Warrant as provided in Section 4. In the event this Warrant does not continue in full force and effect after the consummation of the transactions described in this Section 3, then the Company's securities and property (including cash, where applicable) receivable by the Holders of the Warrant will be delivered to Holder or the Trustee as contemplated by Section 3.2. Extraordinary Events Regarding Common Stock. In the event that the Company shall (a) issue additional shares of the Common Stock as a dividend or other distribution on outstanding Common Stock, (b) subdivide its outstanding shares of Common Stock, or (c) combine its outstanding shares of the Common Stock into a smaller number of shares of the Common Stock, then, in each such event, the Exercise Price shall, simultaneously with the happening of such event, be adjusted by multiplying the then Exercise Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event, and the product so obtained shall thereafter be the Exercise Price then in effect. The Exercise Price, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described herein in this Section 4. The number of shares of Common Stock that the holder of this Warrant shall thereafter, on the exercise hereof as provided in Section 1, be entitled to receive shall be increased to a number determined by multiplying the number of shares of Common Stock that would otherwise (but for the provisions of this Section 4) be issuable on such exercise by a fraction of which (a) the numerator is the Exercise Price that would otherwise (but for the provisions of this Section 4) be in effect, and (b) the denominator is the Exercise Price in effect on the date of such exercise. Certificate as to Adjustments. In each case of any adjustment or readjustment in the shares of Common Stock (or Other Securities) issuable on the exercise of the Warrant, the Company at its expense will promptly cause its Chief Financial Officer or other appropriate designee to compute such adjustment or readjustment in accordance with the terms of the Warrant and prepare a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based, including a statement of (a) the consideration received or receivable by the Company for any 4

additional shares of Common Stock (or Other Securities) issued or sold or deemed to have been issued or sold, (b) the number of shares of Common Stock (or Other Securities) outstanding or deemed to be outstanding, and (c) the Exercise Price and the number of shares of Common Stock to be received upon exercise of this Warrant, in effect immediately prior to such adjustment or readjustment and as adjusted or readjusted as provided in this Warrant. The Company will forthwith mail a copy of each such certificate to the holder of the Warrant and any Warrant agent of the Company (appointed pursuant to Section 11 hereof). Reservation of Stock, Etc., Issuable on Exercise of Warrant. The Company will at all times reserve and keep available, solely for issuance and delivery on the exercise of the Warrant, shares of Common Stock (or Other Securities) from time to time issuable on the exercise of the Warrant. Assignment; Exchange of Warrant. Subject to compliance with applicable securities laws, this Warrant, and the rights evidenced hereby, may be transferred by any registered holder hereof (a "Transferor") in whole or in part. On the surrender for exchange of this Warrant, with the Transferor's endorsement in the form of Exhibit B attached hereto (the "Transferor Endorsement Form") and together with evidence reasonably satisfactory to the Company demonstrating compliance with applicable securities laws, which shall include, without limitation, the provision of a legal opinion from the Transferor's counsel (at the Company's expense) that such transfer is exempt from the registration requirements of applicable securities laws, and with payment by the Transferor of any applicable transfer taxes) will issue and deliver to or on the order of the Transferor thereof a new Warrant of like tenor, in the name of the Transferor and/or the transferee(s) specified in such Transferor Endorsement Form (each a "Transferee"), calling in the aggregate on the face or faces thereof for the number of shares of Common Stock called for on the face or faces of the Warrant so surrendered by the Transferor. Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of any such loss, theft or destruction of this Warrant, on delivery of an indemnity agreement or security reasonably satisfactory in form and amount to the Company or, in the case of any such mutilation, on surrender and cancellation of this Warrant, the Company at its expense will execute and deliver, in lieu thereof, a new Warrant of like tenor. Registration Rights. The Holder of this Warrant has been granted certain registration rights by the Company. These registration rights are set forth in a Registration Rights Agreement entered into by the Company and Purchaser dated as of even date of this Warrant. Maximum Exercise. The Holder shall not be entitled to exercise this Warrant on an exercise date, in connection with that number of shares of Common Stock which would be in excess of the sum of (i) the number of shares of Common Stock beneficially owned by the Holder and its affiliates on an exercise date, and (ii) the number of shares of Common Stock issuable upon the exercise of this Warrant with respect to which the determination of this proviso is being made on an exercise date, which would result in beneficial ownership by the Holder and its affiliates of more than 4.99% of the outstanding shares of Common Stock of the Company on such date. For the purposes of the proviso to the immediately preceding sentence, beneficial ownership shall be determined in accordance with 5

Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13d-3 thereunder. Notwithstanding the foregoing, the restriction described in this paragraph may be revoked upon 75 days prior notice from the Holder to the Company and is automatically null and void upon an Event of Default under the Note. Warrant Agent. The Company may, by written notice to the each Holder of the Warrant, appoint an agent for the purpose of issuing Common Stock (or Other Securities) on the exercise of this Warrant pursuant to Section 1, exchanging this Warrant pursuant to Section 7, and replacing this Warrant pursuant to Section 8, or any of the foregoing, and thereafter any such issuance, exchange or replacement, as the case may be, shall be made at such office by such agent. Transfer on the Company's Books.

Notices, Etc. All notices and other communications from the Company to the Holder of this Warrant shall be mailed by first class registered or certified mail, postage prepaid, at such address as may have been furnished to the Company in writing by such Holder or, until any such Holder furnishes to the Company an address, then to, and at the address of, the last Holder of this Warrant who has so furnished an address to the Company. Voluntary Adjustment by the Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company. Miscellaneous. This Warrant and any term hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the party against which enforcement of such change, waiver, discharge or termination is sought. This Warrant shall be governed by and construed in accordance with the laws of State of New York without regard to principles of conflicts of laws. Any action brought concerning the transactions contemplated by this Warrant shall be brought only in the state courts of New York or in the federal courts located in the state of New York; provided, however, that the Holder may choose to waive this provision and bring an action outside the state of New York. The individuals executing this Warrant on behalf of the Company agree to submit to the jurisdiction of such courts and waive trial by jury. The prevailing party shall be entitled to recover from the other party its reasonable attorney's fees and costs. In the event that any provision of this Warrant is invalid or unenforceable under any applicable statute or rule of law, then such provision shall be deemed inoperative to the extent that it may conflict therewith and shall be deemed modified to conform with such statute or rule of law. Any such provision which may prove invalid or unenforceable under any law shall not affect the validity or enforceability of any other provision of this Warrant. The headings in this Warrant are for purposes of reference only, and shall not limit or otherwise affect any of the terms hereof. The invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of any other provision hereof. The Company acknowledges that legal counsel participated in the preparation of this Warrant and, therefore, stipulates that the rule of construction that ambiguities are to be resolved against the drafting party shall not be applied in the interpretation of this Warrant to favor any party against the other party. 6

withdrawn. Copies of the blanket opinion required by this Section 2(c) shall be delivered to Laurus within the time frame set forth above. 14. Registration Procedures. If and whenever the Company is required by the provisions hereof to effect the registration of any Registrable Securities under the Securities Act, the Company will, as expeditiously as possible: 14.1 prepare and file with the Commission the Registration Statement with respect to such Registrable Securities, respond as promptly as possible to any comments received from the Commission, and use its best efforts to cause the Registration Statement to become and remain effective for the Effectiveness Period with respect thereto, and promptly provide to the Purchaser copies of all filings and Commission letters of comment relating thereto; 14.2 prepare and file with the Commission such amendments and supplements to the Registration Statement and the Prospectus used in connection therewith as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by the Registration Statement and to keep such Registration Statement effective until the expiration of the Effectiveness Period; 14.3 furnish to the Purchaser such number of copies of the Registration Statement and the Prospectus included therein (including each preliminary Prospectus) as the Purchaser reasonably may request to facilitate the public sale or disposition of the Registrable Securities covered by the Registration Statement; 14.4 use its commercially reasonable efforts to register or qualify the Purchaser's Registrable Securities covered by the Registration Statement under the securities or "blue sky" laws of such jurisdictions within the United States as the Purchaser may reasonably request, provided, however, that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction; 14.5 list the Registrable Securities covered by the Registration Statement with any securities exchange on which the Common Stock of the Company is then listed; 14.6 immediately notify the Purchaser at any time when a Prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event of which the Company has knowledge as a result of which the Prospectus contained in such Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing; and 14.7 make available for inspection by the Purchaser and any attorney, accountant or other agent retained by the Purchaser, all publicly available, non-confidential financial and other records, pertinent corporate documents and properties of the Company, and cause the Company's officers, directors and employees to supply all publicly available, non-confidential information reasonably requested by the attorney, accountant or agent of the Purchaser. 10

The Company shall only be responsible for all Registration Expenses. 16. Indemnification. 16.1 In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, the Company will indemnify and hold harmless the Purchaser, and its officers, directors and each other person, if any, who controls the Purchaser within the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which the Purchaser, or such persons may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement under which such Registrable Securities were registered under the Securities Act pursuant to this Agreement, any preliminary Prospectus or final Prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Purchaser, and each such person for any reasonable legal or other expenses incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case if and to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by or on behalf of the Purchaser or any such person in writing specifically for use in any such document. 16.2 In the event of a registration of the Registrable Securities under the Securities Act pursuant to this Agreement, the Purchaser will indemnify and hold harmless the Company, and its officers, directors and each other person, if any, who controls the Company within the meaning of the Securities Act, against all losses, claims, damages or liabilities, joint or several, to which the Company or such persons may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact which was furnished in writing by the Purchaser to the Company expressly for use in (and such information is contained in) the Registration Statement under which such Registrable Securities were registered under the Securities Act pursuant to this Agreement, any preliminary Prospectus or final Prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company and each such person for any reasonable legal or 11

other expenses incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action, provided, however, that the Purchaser will be liable in any such case if and only to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished in writing to the Company by or on behalf of the Purchaser specifically for use in any such document. Notwithstanding the provisions of this paragraph, the Purchaser shall not be required to indemnify any person or entity in excess of the amount of the aggregate net proceeds received by the Purchaser in respect of Registrable Securities in connection with any such registration under the Securities Act. 16.3 Promptly after receipt by a party entitled to claim indemnification hereunder (an "Indemnified Party") of notice of the commencement of any action, such Indemnified Party shall, if a claim for indemnification in respect thereof is to be made against a party hereto obligated to indemnify such Indemnified Party (an "Indemnifying Party"), notify the Indemnifying Party in writing thereof, but the omission so to notify the Indemnifying Party shall not relieve it from any liability which it may have to such Indemnified Party other than under this Section 5(c) and shall only relieve it from any liability which it may have to such Indemnified Party under this Section 5(c) if and to the extent the Indemnifying Party is prejudiced by such omission. In case any such action shall be brought against any Indemnified Party and it shall notify the Indemnifying Party of the commencement thereof, the Indemnifying Party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel satisfactory to such Indemnified Party, and, after notice from the Indemnifying Party to such Indemnified Party of its election so to assume and undertake the defense thereof, the Indemnifying Party shall not be liable to such Indemnified Party under this Section 5(c) for any legal expenses subsequently incurred by such Indemnified Party in connection with the defense thereof; if the Indemnified Party retains its own counsel, then the Indemnified Party shall pay all fees, costs and expenses of such counsel, provided, however, that, if the defendants in any such action include both the indemnified party and the Indemnifying Party and the Indemnified Party shall have reasonably concluded that there may be reasonable defenses available to it which are different from or additional to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, the Indemnified Party shall have the right to select one separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. 16.4 In order to provide for just and equitable contribution in the event of joint liability under the Securities Act in any case in which either (i) the Purchaser, or any officer, director or controlling person of the Purchaser, makes a claim for indemnification pursuant to this Section 5 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 5 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of the Purchaser or such officer, director or controlling person of the Purchaser in circumstances for which indemnification is provided under this Section 5; then, and in each such case, the Company and the Purchaser will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in such proportion so that the Purchaser is responsible only for the portion represented by the percentage that 12

the public offering price of its securities offered by the Registration Statement bears to the public offering price of all securities offered by such Registration Statement, provided, however, that, in any such case, (A) the Purchaser will not be required to contribute any amount in excess of the public offering price of all such securities offered by it pursuant to such Registration Statement; and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 10(f) of the Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation. 17. Representations and Warranties. 17.1 The Common Stock of the Company is registered pursuant to Section 12(b) or 12(g) of the Exchange Act and, except with respect to certain matters which the Company has disclosed to the Purchaser on Schedule 4.21 to the Securities Purchase Agreement, the Company has timely filed all proxy statements, reports, schedules, forms, statements and other documents required to be filed by it under the Exchange Act with such timely filing including the filing within the extension period obtained through filing Form 12b-25. The Company has filed (i) its Annual Report on Form 10-K for its fiscal year ended September 30, 2003 and (ii) its Quarterly Report on Form 10-Q for the fiscal quarters ended December 31, 2003 and March 31, 2004 (collectively, the "SEC Reports"). Each SEC Report was, at the time of its filing, in substantial compliance with the requirements of its respective form and none of the SEC Reports, nor the financial statements (and the notes thereto) included in the SEC Reports, as of their respective filing dates, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The financial statements of the Company included in the SEC Reports comply as to form in all material respects with applicable accounting requirements and the published rules and regulations of the Commission or other applicable rules and regulations with respect thereto. Such financial statements have been prepared in accordance with generally accepted accounting principles ("GAAP") applied on a consistent basis during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto or (ii) in the case of unaudited interim statements, to the extent they may not include footnotes or may be condensed) and fairly present in all material respects the financial condition, the results of operations and the cash flows of the Company and its subsidiaries, on a consolidated basis, as of, and for, the periods presented in each such SEC Report. 17.2 The Common Stock is traded on the OTCBB and satisfies all requirements for the continuation of such trading . The Company has not received any notice that its Common Stock will be ineligible to trade on the OTCBB (except for prior notices which have been fully remedied) or that the Common Stock does not meet all requirements for the continuation of such trading . 17.3 Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has directly or indirectly made any offers or sales of any security or solicited any offers to buy any security under circumstances that would cause the offering of the Securities pursuant to the Securities Purchase Agreement to be integrated with prior offerings by the Company for purposes of the Securities Act which would prevent the Company from selling the Common Stock pursuant to Rule 506 under the Securities Act, or any applicable exchange-related stockholder approval provisions, nor will the 13

Company or any of its affiliates or subsidiaries take any action or steps that would cause the offering of the Securities to be integrated with other offerings. 17.4 The Warrants, the Note and the shares of Common Stock which the Purchaser may acquire pursuant to the Warrants and the Note are all restricted securities under the Securities Act as of the date of this Agreement. The Company will not issue any stop transfer order or other order impeding the sale and delivery of any of the Registrable Securities except as required by applicable federal or state securities laws. 17.5 The Company understands the nature of the Registrable Securities issuable upon the conversion of the Note and the exercise of the Warrant and recognizes that the issuance of such Registrable Securities may have a potential dilutive effect. The Company specifically acknowledges that its obligation to issue the Registrable Securities is binding upon the Company and enforceable regardless of the dilution such issuance may have on the ownership interests of other shareholders of the Company. 17.6 Except for agreements made in the ordinary course of business, there is no agreement that has not been filed with the Commission as an exhibit to a registration statement or to a form required to be filed by the Company under the Exchange Act, the breach of which could reasonably be expected to have a material and adverse effect on the Company and its subsidiaries, or would prohibit or otherwise interfere with the ability of the Company to enter into and perform any of its obligations under this Agreement in any material respect. 17.7 The Company will at all times have authorized and reserved a sufficient number of shares of Common Stock for the full conversion of the Note and exercise of the Warrants. 18. Miscellaneous. 18.1 Remedies. In the event of a breach by the Company or by a Holder, of any of their respective obligations under this Agreement, each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. 18.2 No Piggyback on Registrations. Except as and to the extent specified in Schedule 7(b) hereto, neither the Company nor any of its security holders (other than the Holders in such capacity pursuant hereto) may include securities of the Company in any Registration Statement other than the Registrable Securities, and the Company shall not after the date hereof enter into any agreement providing any such right for inclusion of shares in the Registration Statement to any of its security holders. Except as and to the extent specified in Schedule 7(b) hereto, the Company has not previously entered into any agreement granting any registration rights with respect to any of its securities to any Person that have not been fully satisfied. 14

18.3 Compliance. Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it in connection with sales of Registrable Securities pursuant to the Registration Statement. 18.4 Discontinued Disposition. Each Holder agrees by its acquisition of such Registrable Securities that, upon receipt of a notice from the Company of the occurrence of a Discontinuation Event (as defined below), such Holder will forthwith discontinue disposition of such Registrable Securities under the applicable Registration Statement until such Holder's receipt of the copies of the supplemented Prospectus and/or amended Registration Statement or until it is advised in writing (the "Advice") by the Company that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement. The Company may provide appropriate stop orders to enforce the provisions of this paragraph. For purposes of this Section 7(d), a "Discontinuation Event" shall mean (i) when the Commission notifies the Company whether there will be a "review" of such Registration Statement and whenever the Commission comments in writing on such Registration Statement (the Company shall provide true and complete copies thereof and all written responses thereto to each of the Holders); (ii) any request by the Commission or any other Federal or state governmental authority for amendments or supplements to such Registration Statement or Prospectus or for additional information; (iii) the issuance by the Commission of any stop order suspending the effectiveness of such Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; and/or (v) the occurrence of any event or passage of time that makes the financial statements included in such Registration Statement ineligible for inclusion therein or any statement made in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that, in the case of such Registration Statement or Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. 18.5 Piggy-Back Registrations. If at any time during the Effectiveness Period there is not an effective Registration Statement covering all of the Registrable Securities and the Company shall determine to prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans, then the Company shall send to each Holder written notice of such determination and, if within fifteen days after receipt of such notice, any such Holder shall so request in writing, the Company shall include in such registration statement all or any part of such Registrable Securities such holder requests to be registered to the extent the Company may do so without violating registration rights of others which exist as of the date of this 15

Agreement, subject to customary underwriter cutbacks applicable to all holders of registration rights and subject to obtaining any required the consent of any selling stockholder(s) to such inclusion under such registration statement. 18.6 Amendments and Waivers.

Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of certain Holders and that does not directly or indirectly affect the rights of other Holders may be given by Holders of at least a majority of the Registrable Securities to which such waiver or consent relates; provided, however, that the provisions of this sentence may not be amended, modified, or supplemented except in accordance with the provisions of the immediately preceding sentence. 18.7 Notices.

Registration Statement on Form SB-2 ------------------------------------------------------- Ladies and Gentlemen: As counsel to Mitek Systems, Inc., a Delaware corporation (the "Company"), we have been requested to render our opinion to you in connection with the resale by the individuals or entitles listed on Schedule A attached hereto (the "Selling Stockholders"), of an aggregate of [amount] shares (the "Shares") of the Company's Common Stock. A Registration Statement on Form SB-2 under the Securities Act of 1933, as amended (the "Act"), with respect to the resale of the Shares was declared effective by the Securities and Exchange Commission on [date]. Enclosed is a copy of the Prospectus dated [date] contained in such Registration Statement (the "Prospectus"). We understand that the Shares are to be offered and sold in the manner described in the Prospectus. Except as expressly set forth herein, if a Selling Stockholder sells any of the Shares in accordance with the Prospectus, Mellon Investor Services ("Mellon") may effect transfers of such Shares so sold by such Selling Stockholder provided the following requirements are satisfied: (i) the Selling Stockholder resells such Shares presented for transfer in accordance with the terms of the Prospectus, including the Prospectus delivery requirements; and (ii) as of the date of the particular transfer, Mellon has not been notified that the Registration Statement is no longer effective. In the event a certificate covering Shares, which have been sold by the Selling Stockholder pursuant to the Prospectus, is presented for the transfer of less than the total number of shares represented by such certificate, the shares so sold by a Selling Stockholder may be transferred without restrictive legend; however, the shares remaining which are to be returned to the Selling Stockholder shall bear the identical legend(s) as those affixed to the certificate representing the shares presented for transfer. Very truly yours,

THIS NOTE AND THE COMMON STOCK ISSUABLE UPON CONVERSION OF THIS NOTE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS. THIS NOTE AND THE COMMON STOCK ISSUABLE UPON CONVERSION OF THIS NOTE MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THIS NOTE UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAWS OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO MITEK SYSTEMS, INC. THAT SUCH REGISTRATION IS NOT REQUIRED. SECURED CONVERTIBLE TERM NOTE FOR VALUE RECEIVED, MITEK SYSTEMS, INC., a Delaware corporation (the "BORROWER"), hereby promises to pay to LAURUS MASTER FUND, LTD., a Cayman Islands company, c/o Ironshore Corporate Services Ltd., P.O. Box 1234 G.T., Queensgate House, South Church Street, Grand Cayman, Cayman Islands, Fax: 345-949-9877 (the "HOLDER") or its registered assigns or successors in interest, on order, the sum of Three Million Dollars ($3,000,000), together with any accrued and unpaid interest hereon, on June 11, 2007 (the "MATURITY DATE") if not sooner paid. Capitalized terms used herein without definition shall have the meanings ascribed to such terms in that certain Securities Purchase Agreement dated as of the date hereof between the Borrower and the Holder (the "PURCHASE AGREEMENT"). The following terms shall apply to this Note: ARTICLE I INTEREST & AMORTIZATION 1.1(a) Interest Rate. Subject to Sections 4.11 and 5.6 hereof, interest payable on this Note shall accrue at a rate per annum (the "Interest Rate") equal to the "prime rate" published in The Wall Street Journal from time to time, plus one percent (1.0%). The prime rate shall be increased or decreased as the case may be for each increase or decrease in the prime rate in an amount equal to such increase or decrease in the prime rate; each change to be effective as of the day of the change in such rate. Interest shall be (i) calculated on the basis of a 360 day year, and (ii) payable monthly, in arrears, commencing on July 1, 2004 and on the first business day of each consecutive calendar month thereafter until the Maturity Date (and on the Maturity Date), whether by acceleration or otherwise (each, a "REPAYMENT DATE"). 1.1 (b) Interest Rate Adjustment. The Interest Rate shall be calculated on the last business day of each month hereafter until the Maturity Date (each a "Determination Date") and shall be subject to adjustment as set forth herein. If (i) the Borrower shall have registered the shares of the Borrower's common stock underlying each of the conversion of the Note and that certain warrant issued to Holder on a registration statement declared effective by the Securities and Exchange Commission (the "SEC"), and (ii) the market price (the "Market Price") of the Common Stock as reported by Bloomberg, L.P. on the Principal Market (as defined below) for the five (5) trading days immediately preceding a Determination Date exceeds the then applicable Fixed Conversion Price by at least twenty five percent (25%), the Interest Rate for the succeeding calendar month shall automatically be reduced by 200 basis points (200 b.p.) (2.0.%) for 1

each incremental twenty five percent (25%) increase in the Market Price of the Common Stock above the then applicable Fixed Conversion Price. If (i) the Borrower shall not have registered the shares of the Borrower's common stock underlying the conversion of the Note and that certain warrant issued to Holder on a registration statement declared effective by the SEC and which remains effective, and (ii) the Market Price of the Common Stock as reported by Bloomberg, L.P. on the principal market for the five (5) trading days immediately preceding a Determination Date exceeds the then applicable Fixed Conversion Price by at least twenty five percent (25%), the Interest Rate for the succeeding calendar month shall automatically be decreased by 100 basis points (100 b.p.) (1.0.%) for each incremental twenty five percent (25%) increase in the Market Price of the Common Stock above the then applicable Fixed Conversion Price. In no event shall the Interest Rate be less than zero percent (0%). 1.2 Minimum Monthly Principal Payments. Amortizing payments of the aggregate principal amount outstanding under this Note at any time (the "PRINCIPAL AMOUNT") shall begin on December 1, 2004 and shall recur on the first business day of each succeeding month thereafter until the Maturity Date (each, an "AMORTIZATION DATE"). Subject to Article 3 below, beginning on the first Amortization Date, the Borrower shall make monthly payments to the Holder on each Repayment Date, each in the amount of $90,909.09, together with any accrued and unpaid interest to date on such portion of the Principal Amount plus any and all other amounts which are then owing under this Note, the Purchase Agreement or any other Related Agreement but have not been paid (collectively, the "MONTHLY AMOUNT"). Any Principal Amount that remains outstanding on the Maturity Date shall be due and payable on the Maturity Date. ARTICLE II CONVERSION REPAYMENT 2.1 (a) Payment of Monthly Amount in Cash or Common Stock. Each month by the fifth (5th) business day prior to each Amortization Date (the "NOTICE DATE"), the Holder shall deliver to Borrower a written notice in the form of Exhibit B attached hereto converting the Monthly Amount payable on the next Repayment Date in either cash or Common Stock, or a combination of both (each, a "REPAYMENT NOTICE"). If a Repayment Notice is not delivered by the Holder on or before the applicable Notice Date for such Repayment Date, then the Borrower shall pay the Monthly Amount due on such Repayment Date in cash. Any portion of the Monthly Amount paid in cash on a Repayment Date, shall be paid to the Holder an amount equal to 102% of the principal portion of the Monthly Amount due and owing to Holder on the Repayment Date. If the Holder converts all or a portion of the Monthly Amount in shares of Common Stock as provided herein, the number of such shares to be issued by the Borrower to the Holder on such Repayment Date shall be the number determined by dividing (x) the portion of the Monthly Amount to be paid in shares of Common Stock, by (y) the then applicable Fixed Conversion Price. For purposes hereof, the initial "FIXED CONVERSION PRICE" means $0.70. (b) Monthly Amount Conversion Guidelines. Subject to Sections 2.1(a), 2.2, and 3.2 hereof, the Holder shall convert all or a portion of the Monthly Amount due on each Repayment Date in shares of Common Stock if the average closing price of the Common Stock as reported by Bloomberg, L.P. on the Principal Market for the five (5) trading days immediately preceding such 2

Repayment Date was greater than or equal to 110% of the Fixed Conversion Price, provided, however, that such conversions shall not exceed twenty five percent (25%) of the aggregate dollar trading volume of the Common Stock for the five (5) day trading period immediately preceding delivery of a Notice of Conversion to the Borrower. Any part of the Monthly Amount due on a Repayment Date that the Holder has not converted into shares of Common Stock shall be paid by the Borrower in cash on such Repayment Date. Any part of the Monthly Amount due on such Repayment Date which must be paid in cash (as a result of the closing price of the Common Stock on one or more of the five (5) trading days preceding the applicable Repayment Date being less than 110% of the Fixed Conversion Price) shall be paid in cash at the rate of 102% of the Monthly Amount otherwise due on such Repayment Date, within three (3) business days of the applicable Repayment Date. 2.2 No Effective Registration. Notwithstanding anything to the contrary herein, none of the Borrower's obligations to the Holder may be converted into Common Stock unless (i) either (x) an effective current Registration Statement (as defined in the Registration Rights Agreement) covering the shares of Common Stock to be issued in connection with satisfaction of such obligations exists or (y) an exemption from registration of the Common Stock is available to pursuant to Rule 144 of the Securities Act and (ii) no Event of Default hereunder exists and is continuing, unless such Event of Default is cured within any applicable cure period or is otherwise waived in writing by the Holder in whole or in part at the Holder's option. 2.3 Optional Redemption in Cash. The Borrower will have the option of prepaying this Note ("OPTIONAL REDEMPTION") by paying to the Holder a sum of money equal to one hundred twenty percent (120%) of the principal amount of this Note together with accrued but unpaid interest thereon and any and all other sums due, accrued or payable to the Holder arising under this Note, the Purchase Agreement, or any Related Agreement (the "REDEMPTION AMOUNT") outstanding on the day written notice of redemption (the "NOTICE OF REDEMPTION") is given to the Holder. The Notice of Redemption shall specify the date for such Optional Redemption (the "REDEMPTION PAYMENT DATE") which date shall be seven (7) business days after the date of the Notice of Redemption (the "REDEMPTION PERIOD"). A Notice of Redemption shall not be effective with respect to any portion of this Note for which the Holder has a pending election to convert pursuant to Section 3.1, or for conversions initiated or made by the Holder pursuant to Section 3.1 during the Redemption Period. The Redemption Amount shall be determined as if such Holder's conversion elections had been completed immediately prior to the date of the Notice of Redemption. On the Redemption Payment Date, the Redemption Amount must be paid in good funds to the Holder. In the event the Borrower fails to pay the Redemption Amount on the Redemption Payment Date as set forth herein, then such Redemption Notice will be null and void. ARTICLE III CONVERSION RIGHTS 3.1. Holder's Conversion Rights. The Holder shall have the right, but not the obligation, to convert all or any portion of the then aggregate 3

outstanding principal amount of this Note, together with interest and fees due hereon, into shares of Common Stock subject to the terms and conditions set forth in this Article III. The Holder may exercise such right by delivery to the Borrower of a written notice of conversion not less than one (1) day prior to the date upon which such conversion shall occur. 3.2 Conversion Limitation. Notwithstanding anything contained herein to the contrary, the Holder shall not be entitled to convert pursuant to the terms of this Note an amount that would be convertible into that number of Conversion Shares which would exceed the difference between the number of shares of Common Stock beneficially owned by such Holder or issuable upon exercise of warrants held by such Holder and 4.99% of the outstanding shares of Common Stock of the Borrower. For the purposes of the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and Regulation 13d-3 thereunder. The Holder may void the Conversion Share limitation described in this Section 3.2 upon 75 days prior notice to the Borrower or without any notice requirement upon an Event of Default. 3.3 Mechanics of Holder's Conversion. (a) In the event that the Holder elects to convert this Note into Common Stock, the Holder shall give notice of such election by delivering an executed and completed notice of conversion ("NOTICE OF CONVERSION") to the Borrower and such Notice of Conversion shall provide a breakdown in reasonable detail of the Principal Amount, accrued interest and fees being converted. On each Conversion Date (as hereinafter defined) and in accordance with its Notice of Conversion, the Holder shall make the appropriate reduction to the Principal Amount, accrued interest and fees as entered in its records and shall provide written notice thereof to the Borrower within two (2) business days after the Conversion Date. Each date on which a Notice of Conversion is delivered or telecopied to the Borrower in accordance with the provisions hereof shall be deemed a Conversion Date (the "CONVERSION DATE"). A form of Notice of Conversion to be employed by the Holder is annexed hereto as Exhibit A. (a) (b) Pursuant to the terms of the Notice of Conversion, the Borrower will issue instructions to the transfer agent accompanied by an opinion of counsel within one (1) business day of the date of the delivery to Borrower of the Notice of Conversion and shall cause the transfer agent to transmit the certificates representing the Conversion Shares to the Holder by crediting the account of the Holder's designated broker with the Depository Trust Corporation ("DTC") through its Deposit Withdrawal Agent Commission ("DWAC") system within three (3) business days after receipt by the Borrower of the Notice of Conversion (the "DELIVERY DATE"). In the case of the exercise of the conversion rights set forth herein the conversion privilege shall be deemed to have been exercised and the Conversion Shares issuable upon such conversion shall be deemed to have been issued upon the date of receipt by the Borrower of the Notice of Conversion. The Holder shall be treated for all purposes as the record holder of such Common Stock, unless the Holder provides the Borrower written instructions to the contrary. 3.4 Conversion Mechanics. (a) The number of shares of Common Stock to be issued upon each conversion of this Note shall be determined by dividing that portion of the principal and interest and fees to be converted, if any, by the then applicable Fixed Conversion Price. In the event of any conversions of outstanding principal amount under this Note in part pursuant to this Article III, such conversions shall be deemed to constitute conversions of outstanding principal amount applying to Monthly Amounts for the remaining Repayment Dates in chronological order. By way of example, if the original principal amount of this Note is $200,000 and the Holder converted $0 of such original principal amount prior to the first Repayment Date, then (1) the principal amount of the Monthly Amount due on the first Repayment Date would equal $0, (2) the principal amount of the 4

Monthly Amount due on the second Repayment Date would equal $ and (3) the principal amount of the Monthly Amount due on the third Repayment Dates would be $18,181.81. (b) The Fixed Conversion Price and number and kind of shares or other securities to be issued upon conversion is subject to adjustment from time to time upon the occurrence of certain events, as follows: A. Stock Splits, Combinations and Dividends. If the shares of Common Stock are subdivided or combined into a greater or smaller number of shares of Common Stock, or if a dividend is paid on the Common Stock in shares of Common Stock, the Fixed Conversion Price or the Conversion Price, as the case may be, shall be proportionately reduced in case of subdivision of shares or stock dividend or proportionately increased in the case of combination of shares, in each such case by the ratio which the total number of shares of Common Stock outstanding immediately after such event bears to the total number of shares of Common Stock outstanding immediately prior to such event. B. During the period the conversion right exists, the Borrower will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of Common Stock upon the full conversion of this Note. The Borrower represents that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable. The Borrower agrees that its issuance of this Note shall constitute full authority to its officers, agents, and transfer agents who are charged with the duty of executing and issuing stock certificates to execute and issue the necessary certificates for shares of Common Stock upon the conversion of this Note. C. Share Issuances. Subject to the provisions of this Section 3.4, if the Borrower shall at any time prior to the conversion or repayment in full of the Principal Amount issue any shares of Common Stock or securities convertible into Common Stock to a person other than the Holder (except (i) pursuant to Subsections A or B above; (ii) pursuant to options, warrants, or other obligations to issue shares outstanding on the date hereof as disclosed to Holder in writing; or (iii) pursuant to options that may be issued under any employee incentive stock option and/or any qualified stock option plan adopted by the Borrower) for a consideration per share (the "Offer Price") less than the Fixed Conversion Price in effect at the time of such issuance, then the Fixed Conversion Price shall be immediately reset to such lower Offer Price at the time of issuance of such securities. D. Reclassification, etc. If the Borrower at any time shall, by reclassification or otherwise, change the Common Stock into the same or a different number of securities of any class or classes, this Note, as to the unpaid Principal Amount and accrued interest thereon, shall thereafter be deemed to evidence the right to purchase an adjusted number of such securities and kind of securities as would have been issuable as the result of such change with respect to the Common Stock immediately prior to such reclassification or other change. 3.5 Issuance of New Note. Upon any partial conversion of this Note, a new Note containing the same date and provisions of this Note shall, at the request of the Holder, be issued by the Borrower to the Holder for the principal balance of this Note and interest which shall not have been converted or paid. 5

The Borrower will pay no costs, fees or any other consideration to the Holder for the production and issuance of a new Note. ARTICLE IV EVENTS OF DEFAULT Upon the occurrence and continuance of an Event of Default beyond any applicable grace period, the Holder may make all sums of principal, interest and other fees then remaining unpaid hereon and all other amounts payable hereunder immediately due and payable. In the event of such an acceleration, within five (5) days after written notice from Holder to Borrower (each occurrence being a "DEFAULT NOTICE PERIOD") the amount due and owing to the Holder shall be 130% of the outstanding principal amount of the Note (plus accrued and unpaid interest and fees, if any) (the "DEFAULT PAYMENT"). If, with respect to any Event of Default, the Borrower cures the Event of Default, the Event of Default will be deemed to no longer exist and any rights and remedies of Holder pertaining to such Event of Default will be of no further force or effect. The Default Payment shall be applied first to any fees due and payable to Holder pursuant to the Note or the Related Agreements, then to accrued and unpaid interest due on the Note and then to outstanding principal balance of the Note. The occurrence of any of the following events set forth in Sections 4.1 through 4.10, inclusive, is an "EVENT OF DEFAULT": 4.1 Failure to Pay Principal, Interest or other Fees. The Borrower fails to pay when due any installment of principal, interest or other fees hereon in accordance herewith, or the Borrower fails to pay when due any amount due under any other promissory note issued by Borrower, and in any such case, such failure shall continue for a period of three (3) days following the date upon which any such payment was due. 4.2 Breach of Covenant. The Borrower breaches any covenant or other term or condition of this Note, the Purchase Agreement or any Related Agreement in any material respect and such breach, if subject to cure, continues for a period of fifteen (15) days after the occurrence thereof. 4.3 Breach of Representations and Warranties. Any representation or warranty of the Borrower made herein, in the Purchase Agreement, or in any Related Agreement shall be false or misleading in any material respect on the date that such representation or warranty was made or deemed made. 4.4 Receiver or Trustee. The Borrower shall make an assignment for the benefit of creditors, or apply for or consent to the appointment of a receiver or trustee for it or for a substantial part of its property or business; or such a receiver or trustee shall otherwise be appointed. 4.5 Judgments. Any money judgment, writ or similar final process shall be entered or filed against the Borrower or any of its property or other assets for more than $50,000, and shall remain unvacated, unbonded or unstayed for a period of thirty (30) days. 6

4.6 Bankruptcy. Bankruptcy, insolvency, reorganization or liquidation proceedings or other proceedings or relief under any bankruptcy law or any law for the relief of debtors shall be instituted by or against the Borrower. 4.7 Stop Trade. An SEC stop trade order or Principal Market trading suspension of the Common Stock shall be in effect for five (5) consecutive days or five (5) days during a period of ten (10) consecutive days, excluding in all cases a suspension of all trading on a Principal Market, provided that the Borrower shall not have been able to cure such trading suspension within thirty (30) days of the notice thereof or list the Common Stock on another Principal Market within sixty (60) days of such notice. The "Principal Market" for the Common Stock shall include the NASD OTC Bulletin Board, NASDAQ SmallCap Market, NASDAQ National Market System, American Stock Exchange, or New York Stock Exchange (whichever of the foregoing is at the time the principal trading exchange or market for the Common Stock, or any securities exchange or other securities market on which the Common Stock is then being listed or traded. 4.8 Failure to Deliver Common Stock or Replacement Note. The Borrower shall fail (i) to timely deliver Common Stock to the Holder pursuant to and in the form required by this Note, and Section 9 of the Purchase Agreement, if such failure to timely deliver Common Stock shall not be cured within two (2) business days or (ii) to deliver a replacement Note to Holder within seven (7) business days following the required date of such issuance pursuant to this Note, the Purchase Agreement or any Related Agreement (to the extent required under such agreements). 4.9 Default Under Related Agreements or Other Agreements. The occurrence and continuance of any Event of Default as defined in the Related Agreements or any event of default (or similar term) under any other indebtedness. 4.10 Change in Control. The occurrence of a change in the controlling ownership of the Company. DEFAULT RELATED PROVISIONS 4.11 Payment Grace Period. Following the occurrence and continuance of an Event of Default beyond any applicable cure period hereunder, the Borrower shall pay the Holder a default interest rate of two percent (2%) per month on all amounts due and owing under the Note,, which default interest shall be payable upon demand. 4.12 Conversion Privileges. The conversion privileges set forth in Article III shall remain in full force and effect immediately from the date hereof and until this Note is paid in full. 4.13 Cumulative Remedies. The remedies under this Note shall be cumulative. ARTICLE V MISCELLANEOUS 5.1 Failure or Indulgence Not Waiver. No failure or delay on the part of the Holder hereof in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of 7

any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privilege. All rights and remedies existing hereunder are cumulative to, and not exclusive of, any rights or remedies otherwise available. 5.2 Notices. Any notice herein required or permitted to be given shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party notified, (b) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient, if not, then on the next business day, (c) five days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt.

A Notice of Conversion shall be deemed given when made to the Borrower pursuant to the Purchase Agreement. 5.3 Amendment Provision. The term "Note" and all reference thereto, as used throughout this instrument, shall mean this instrument as originally executed, or if later amended or supplemented, then as so amended or supplemented, and any successor instrument issued pursuant to Section 3.5 hereof, as it may be amended or supplemented. 5.4 Assignability. This Note shall be binding upon the Borrower and its successors and assigns, and shall inure to the benefit of the Holder and its successors and assigns, and may be assigned by the Holder in accordance with the requirements of the Purchase Agreement. This Note shall not be assigned by the Borrower without the consent of the Holder. 5.5 Governing Law. This Note shall be governed by and construed in accordance with the laws of the State of New York, without regard to principles of conflicts of laws. Any action brought by either party against the other concerning the transactions contemplated by this Agreement shall be brought only in the state courts of New York or in the federal courts located in the state of New York. Both parties and the individual signing this Note on behalf of the Borrower agree to submit to the jurisdiction of such courts. The prevailing party shall be entitled to recover from the other party its reasonable attorney's fees and costs. In the event that any provision of this Note is invalid or unenforceable under any applicable statute or rule of law, then such provision shall be deemed inoperative to the extent that it may conflict therewith and shall be deemed modified to conform with such statute or rule of law. Any such provision which may prove invalid or unenforceable under any law shall not affect the validity or unenforceability of any other provision of this Note. Nothing contained herein shall be deemed or operate to preclude the Holder from bringing suit or taking other legal action against the Borrower in any other jurisdiction to collect on the Borrower's obligations to Holder, to 8
