NOTES TO FINANCIAL STATEMENTS 1. Business and Organization of the Company: Ibex Technologies, Inc. (the Company) designs, develops, and markets fax-on-demand software systems. The Company distributes its products primarily through its direct sales force, master distributors and various value-added resellers to end users and service providers in North America, Europe and Asia. 2. Summary of Significant Accounting Policies: Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain Risks and Concentrations Financial instruments that potentially subject the Company to concentrations of credit risks comprise, principally, cash and trade accounts receivable. At December 31, 1995, the Company had on deposit approximately $222,000, including amounts representing outstanding checks, at an established financial institution and has not experienced any losses relating to its bank deposits. These deposits are federally insured to the extent of $100,000. Ongoing customer credit evaluations are performed by the Company, and collateral is not required. The Company maintains allowances for potential returns and credit losses, and such returns and losses have generally been within management's expectations. One customer accounted for 42% and 12% of accounts receivable and sales at December 31, 1995. Two customers accounted for 39% of accounts receivable at December 31, 1994. F-30 IBEX TECHNOLOGIES, INC. NOTES TO FINANCIAL STATEMENTS, Continued 2. Summary of Significant Accounting Policies, continued: The Company's products include components subject to rapid technological change. Significant technological change could adversely affect the Company's operating results and subject the Company to returns of product and inventory losses. While the Company has ongoing programs to minimize the adverse effect of such changes and consider technological change in estimating its allowances, such estimates could change in the future. Inventories Inventories are stated at the lower of cost (first-in, first-out basis) or market. Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is provided using the straight-line method over the estimated useful lives of the respective assets, generally five to ten years. Software Production Costs Costs related to the conceptual formulation and design of software products are expensed as research and development while costs incurred subsequent to establishing technological feasibility of software products are capitalized until general release of the product. Generally, technological feasibility is established upon completion of a working model. Costs incurred subsequent to such point have not been significant in 1995 or 1994, and all such costs have been expensed. Revenue Recognition Product revenue is recognized upon shipment provided no significant vendor obligations remain and collection of the resulting receivable is deemed probable by management. Provisions for estimated product returns are recorded at the time products are shipped. Revenue earned on service contracts is recognized proratably over the term of the contract. Advertising Costs Advertising costs, included in sales and marketing expenses, are expensed as incurred and were $223,630 and $178,291 in 1995 and 1994, respectively. F-31 2. Summary of Significant Accounting Policies, continued: Foreign Currency Translation Foreign currency gains and losses related to international sales, which have not been material, are reported in the statement of operations. Income Taxes The Company uses the liability method of accounting for income taxes. Deferred income taxes are recorded based on the difference between financial statement and income tax bases of assets and liabilities and available loss or credit carry forwards. Recent Pronouncements During March 1995, the Financial Accounting Standards Board issued Statement No. 121 (SFAS 121), "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," which requires the Company to review for impairment of long-lived assets, certain identifiable intangibles, and goodwill related to those assets whenever events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable. In certain situations, an impairment loss would be recognized. SFAS 121 will become effective for the Company's year ending December 31, 1996. The Company has studied the implications of SFAS 121 and, based on its initial evaluation, does not expect it to have a material impact on the Company's financial condition or results of operations. During October 1995, the Financial Accounting Standards Board issued Statement No. 123 (SFAS 123), "Accounting for Stock-Based Compensation" which establishes a fair value based method of accounting for stock-based compensation plans and requires additional disclosures for those companies who elect not to adopt the new method of accounting. The Company intends to continue to account for employee purchase rights and stock options under APB Opinion No. 25, "Accounting for Stock Issued to Employees" and will be required to provide additional disclosures in the financial statements for the year ended December 31, 1996.

Bank Line of Credit: The Company has a $250,000 line of credit which expired on July 26, 1996. Borrowings under this line of credit agreement are collateralized by all inventory of the Company and bear interest at the bank's prime rate plus 2% (10.50% at December 31, 1995). As of and during the year ended December 31, 1995, there were no borrowings under this line of credit agreement. The line of credit agreement contains certain financial covenants including minimum levels of tangible net worth, working capital and debt service ratios. F-33 6. Notes Payable: In 1995, the Company purchased exclusive license and development rights for a software product, in exchange for 4,475 shares of its common stock at an estimated fair value of $27,969 and a non-interest bearing note payable for $150,000. The note, which is not collateralized, is payable in installments of $25,000, with the first payment due on March 17, 1995, the second payment due July 1, 1995 and quarterly thereafter. 7. Preferred Stock: The Company has 5,000,000 shares of no par value preferred stock authorized. As of December 31, 1995 and 1994, 48,035 shares are issued and outstanding. The preferred stock is convertible into common stock (by formula) (i) at the option of the preferred stockholder at any time after the date of issuance, or (ii) automatically in the case of a public offering of not less than $8,000,000. The preferred stock provides for non-cumulative preferential dividends of $.50 per year, and additional dividends may be declared by the Board of Directors. The holders of preferred stock are entitled to vote, and have the number of votes equal to the number of common shares into which their shares are convertible. The preferred shares have liquidation preference for $6.25 per share, and are entitled to participate in the distribution of the remaining assets of the Company. 8. Stock Option Plan: In August 1996, the Board of Directors and the shareholders of the Company ratified the 1992 Stock Option Plan which reserves a maximum of 20,000 shares of authorized but unissued common stock for the issuance upon exercise of nonstatutory stock options granted to employees, non-employee directors and consultants of the Company. The options are issued at fair market value as determined by the Board of Directors. The vesting period and exercise term are determined by the Board of Directors at the time the options are granted. The options outstanding at December 31, 1995 vest over a three-year period, have an exercise term of ten years, and exercise prices between $3.85 and $13.75 per share. F-34 8.

Contingency: The Company is a defendant in a legal action. While the outcome cannot be determined at this time, management is of the opinion that the liability, if any, resulting from this legal action will not have a material effect on the Company's financial position, results of operations or cash flows. 12. Fair Value of Financial Instruments: The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: Cash The carrying amount approximates fair value. Accounts Receivable The carrying value of the Company's receivables is assumed to approximate fair value due to their short-term maturities. Notes Payable The Company's notes payable consists of a non-interest bearing note payable to another software company. There is no established market and it is not practicable to estimate the fair value of this financial instrument. 13. Non-Monetary Transactions: The Company supplies its software at the current list price to customers in exchange for computer software, marketing, advertising and telephone services. Total revenue recorded in exchange for a corresponding value of services received during the years amounted to $59,054 and $23,531 in 1995 and 1994, respectively. F-38 14. Subsequent Events: On August 12, 1996, the Company entered into an agreement to merge with another company. Pursuant to the terms of the merger agreement, each share of common and preferred stock of the Company will be converted into common stock of Castelle, a manufacturer of fax and print server devices, based upon a formula using the market price for Castelle at the date of closing.

In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the Company's financial position, results of operations and cash flows at the dates and for the periods indicated have been included. The results of operations for the interim period presented are not necessarily indicative of the results for the year ending December 31, 1996.
