NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)

1.	Basis of Presentation:

	The accompanying unaudited condensed consolidated financial statements include the accounts of Castelle and its wholly-owned subsidiary in the United Kingdom (collectively, the “Company”). These financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations. Because all of the disclosures required by accounting principles generally accepted in the United States of America are not included in the accompanying condensed consolidated financial statements and related notes, they should be read in conjunction with the audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005. All intercompany balances and transactions have been eliminated. In the Company’s opinion, all adjustments (consisting only of normal recurring adjustments) 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 condensed consolidated balance sheet data as of December 31, 2005 was derived from the Company’s audited financial statements and does not include all of the disclosures required by accounting principles generally accepted in the United States of America. The results of operations for the periods presented are not necessarily indicative of results that the Company expects for any future period, or for the entire year.

	The preparation of financial statements in conformity with generally accepted accounting principles requires the Company 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.

2.	Net Income Per Share:

	Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding for such period. Diluted net income per share reflects the potential dilution from the exercise or conversion of other securities into common stock that were outstanding during the period. Diluted net income per share excludes shares that are potentially dilutive if their effect is anti-dilutive. Dilutive potential shares consist of incremental common shares issuable upon exercise of stock options.

	Basic and diluted net income per share are calculated as follows for the three and nine months ended September 30, 2006 and 2005 (unaudited, in thousands, except per share amounts):


	Three months ended				Nine months ended

	September 30, 2006		September 30, 2005		September 30, 2006		September 30, 2005

Basic:
Weighted average common shares outstanding		4,026		3,940		4,017		3,875

Net income	$	237	$	248	$	409	$	699

Net income per common share – basic	$	0.06	$	0.06	$	0.10	$	0.18


Diluted:
Weighted average common shares outstanding		4,026		3,940		4,017		3,875
Common equivalent shares from stock options		440		627		456		619

Shares used in per share calculation – diluted		4,466		4,567		4,473		4,494

Net income	$	237	$	248	$	409	$	699

Net income per common share – diluted	$	0.05	$	0.05	$	0.09	$	0.16


	The calculation of diluted shares outstanding for the three months ended September 30, 2006 and 2005 excluded 414,000 shares and 35,000 shares, respectively, of common stock issuable upon exercise of outstanding stock options as their effect was anti-dilutive in the period. The calculation of diluted shares outstanding for the nine months ended September 30, 2006 and 2005 excluded 414,000 shares and 133,000 shares, respectively, of common stock issuable upon exercise of outstanding stock options as their effect was anti-dilutive in the period.

3.	Share-Based Compensation


	The Company grants stock options to employees, non-employee directors and consultants under its 2002 Equity Incentive Plan (the “2002 Plan”). Prior to January 1, 2006, the Company accounted for these share-based awards under the intrinsic value method of Accounting Principles Board (“APB”) No. 25, “Accounting for Stock Issued to Employees” (“APB No. 25”). This method under APB No. 25 resulted in no expense being recorded for stock option grants. Effective January 1, 2006, the Company adopted Statement of Financial Accounting Standard No. 123 (Revised 2004) “Share-Based Payment”, (“SFAS No. 123R”), which replaces SFAS No. 123, “Accounting for Stock-Based Compensation” (“SFAS No 123”) and supersedes APB No. 25. SFAS No. 123R requires that compensation cost relating to share-based payment transactions be recognized in the Company’s financial statements. That cost is measured based upon the fair value of the option issued. SFAS No. 123R applies to all of the Company’s outstanding unvested share-based payment awards as of January 1, 2006 and all prospective awards using the modified prospective transition method without restatement of prior periods. Accordingly, the Company’s share-based compensation cost is measured at the grant date, based on the fair value of the award, and is either recognized as an expense over the requisite service period using the graded, or accelerated, attribution method, or capitalized as inventory.

	The fair value of each of the Company’s option awards is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. Expected stock price volatility is based on historical volatility of the Company’s common stock over the estimated expected life of the options. The expected life of options granted is based on historical experience and on the terms and conditions of the options. Separate groups of option awardees that have similar historical exercise behavior are considered separately for valuation purposes. The ranges of the assumptions given below that were used to value option grants result from certain groups of option awardees exhibiting different behavior. Additionally, the Company uses historical data to estimate employee forfeitures. Our estimated cumulative forfeiture rates over the vesting period of the options granted were calculated at

	2% for directors and 20% for employees. The risk-free rates are based on the U.S. Treasury yield curve in effect at the time of grant.

	As of September 30, 2006, the Company had 850,000 shares of common stock reserved for issuance under the 2002 Plan, of which 635,000 shares were subject to outstanding options and 213,000 shares were available for future grants of stock awards. There were 646,000 shares subject to options outstanding under prior plans.

	Options granted under the 2002 Plan as well as those granted under the prior option plans generally become exercisable, and the Company’s right to repurchase shares issued and sold pursuant to stock purchase rights under these plans generally lapses, at a rate of one-quarter of the shares subject to the options or purchased under stock purchase rights at the end of the first year and thereafter ratably over the next three years. Awards under the 2002 Plan and the prior option plans generally expire seven years from the date of grant.

	The fair value of each option grant is estimated on the date of grant using the Black-Scholes-Merton model with the following assumptions for options granted during the nine months ended September 30, 2006:


	September 30, 2006


Risk-free interest rate		4.58% - 5.13%

Expected life		3 - 5 years

Expected dividends		—

Volatility		49% - 59%


	A summary of option activity during the nine months ended September 30, 2006 is presented below (unaudited):


Options	Shares (in thousands)			Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (in years)		Aggregate Intrinsic Value (in thousands)


Outstanding at Dec. 31, 2005		1,302		$	1.94		4.2	$	2,526
Granted		29		$	3.10
Exercised		(41	)	$	0.98
Forfeited		(4	)	$	2.76
Expired		(3	)	$	3.35
Outstanding at September 30, 2006		1,281		$	1.99		3.7	$	2,555

Exercisable at September 30, 2006		1,030		$	1.73		3.2	$	1,781

	The weighted-average grant-date fair value of options granted during the nine months ended September 30, 2006 and 2005 was $1.56 and $2.68, respectively. The total intrinsic value of all options (which is the amount by which the stock price exceeded the exercise price of the options at the date of exercise) exercised during the nine months ended September 30, 2006 and 2005 was $87,000 and $400,000, respectively.

	As of September 30, 2006, there was $206,000 of total unrecognized compensation cost related to unvested stock options that is expected to be recognized over a weighted-average remaining vesting period of 0.9 years.

	*Share-Based Compensation Expense*: Total compensation costs recognized in the Company’s financial statements relating to its stock option plans in the three and nine months ended September 30, 2006 were $71,000 and $236,000, respectively, and included the following financial statement line items (unaudited, in thousands):


	Three months ended September 30, 2006		Nine months ended September 30, 2006


Share-based compensation expense by caption:

Cost of products	$	6	$	6

Cost of services		8		24

Research and development		23		81

Sales and marketing		7		24

General and administrative		27		101


Total share-based compensation:	$	71	$	236


	Share-based compensation expense of $13,000 was capitalized and included in inventory on the Company’s condensed consolidated balance sheet as of September 30, 2006. No tax benefits were recorded with respect to share-based compensation expense recorded during the three and nine months ended September 30, 2006.

	For the three and nine-month periods ended September 30, 2006, the Company recorded $71,000 and $236,000 of expense associated with share-based payments, respectively, which would not have been recorded prior to the adoption of SFAS No. 123R. As a result of the adoption of SFAS No. 123R, income from continuing operations was reduced by $71,000 and $236,000, respectively, for the three and nine months ended September 30, 2006. Basic net income per share for the three and nine-months ended September 30, 2006 was $0.02 and $0.06 lower, respectively as a result of the adoption of SFAS No. 123R. Diluted net income per share for the three and nine-months ended September 30, 2006 was $0.02 and $0.05 lower, respectively as a result of the adoption of SFAS No. 123R. There was no impact on cash flows as a result of the adoption of SFAS No. 123R.

	Through 2005, the Company accounted for its stock option plans using the intrinsic value method. Had the fair value method prescribed by SFAS 123 been used to account for share-based compensation for the three and nine months ended September 30, 2005, net income and net income per share would have been reduced to the following pro forma amounts (unaudited, in thousands, except per share amounts):


		Three months ended September 30, 2005			Nine months ended September 30, 2005


Net income – as reported	$	248		$	699
Fair value of stock-based compensation		(69	)		(243	)

Net income – pro forma	$	179		$	456


Net income per share – basic – as reported	$	0.06		$	0.18

Net income per share – diluted – as reported	$	0.05		$	0.16

Net income per share – basic – pro forma	$	0.05		$	0.12

Net income per share – diluted – pro forma	$	0.04		$	0.10


4.	Inventories:

	Inventories are stated at the lower of standard cost (which approximates cost on a first-in, first-out basis) or market. Inventory details are as follows (unaudited, in thousands):


	September 30, 2006		December 31, 2005

Raw materials	$	759	$	745
Work in process		20		55
Finished goods		351		356

Total inventory	$	1,130	$	1,156


	After the announcement by the Company’s component suppliers that new components are available to replace certain of their end-of-life components currently used in the Company’s FaxPress products, the Company purchased approximately two years worth of these end-of-life components in an effort to guarantee a smooth supply of its FaxPress Products to its customers while it continues to develop new replacement products. As of September 30, 2006, the Company had approximately $291,000 worth of end-of-life components as compared to $390,000 at December 31, 2005. The Company believes that most of these end-of-life components will be utilized in the following two years, resulting in insignificant amounts of excessive inventory, or none at all.

	Inventories are reduced for excess and obsolete products. These write-downs are based on management’s review of inventories on hand on a quarterly basis, compared to management’s assumptions about future demand, market conditions and anticipated timing of the release of product upgrades or next generation products. If actual market conditions for future demand are less favorable than those projected by the Company or if product upgrades or next generation products are released earlier than anticipated, additional inventory write-downs may be required. Obsolete products removed from gross inventory are physically scrapped.

5.	Segment Information:

	The Company has determined that it operates in one segment. Sales by geographic area are determined by the location of the customer and are summarized as follows (unaudited, in thousands):

6.	Commitments and Contingencies:

	Contingencies

	From time to time and in the ordinary course of business, the Company is involved in various legal proceedings and third party assertions of patent or trademark infringement claims against the Company in the form of letters and other forms of communication. The Company is not currently involved in any litigation which, in management’s opinion, would have a material adverse effect on its business, operating results, cash flows or financial condition. However, there can be no assurance that any such proceeding will not escalate or otherwise become material to the Company’s business in the future.

	Lease Commitments

	The following represents combined aggregate maturities for all of the Company’s financing and commitments under operating and capital leases as of September 30, 2006 (unaudited, in thousands):

	Operating Leases		Capital Lease Obligations		Total Commitments

Three months ending December 31, 2006	$	52	$	2	$	54
Year ending December 31, 2007		207		—		207
Year ending December 31, 2008		207		—		207
Year ending December 31, 2009		86		—		86

Total Commitments	$	552	$	2	$	554


	The lease on the Company’s headquarters facility was extended for a term of five years commencing on June 1, 2004 and expiring on May 31, 2009, with one conditional three-year renewal option, which if exercised, would extend the lease to May 31, 2012 commencing with rent at ninety-five percent of

	fair market value.

	The Company leases certain of its equipment under various operating and capital leases that expire at various dates through the end of fiscal 2006. The lease agreements frequently include renewal and escalation clauses and purchase provisions and require the Company to pay taxes, insurance and maintenance costs. As of September 30, 2006, we have no long term debts related to these operating and capital leases.

	The Company renewed its line of credit with Silicon Valley Bank in July 2006, which now matures on July 30, 2007. The revolving line of credit provides for borrowings of up to $6.0 million. Borrowings under this line of credit agreement are collateralized by all of the Company’s assets and bear interest at the bank’s prime rate plus 0.50%. The Company is required to maintain certain minimum cash and investment balances with the bank and to meet certain other financial covenants. As of September 30, 2006, the Company has not drawn down on the line of credit and was in compliance with debt covenants and all other terms of the agreement.

	Product Warranties and Guarantor Arrangements

	The Company offers warranties on certain products and records a liability for the estimated future costs associated with warranty claims, which is based upon historical experience and the Company’s estimate of the level of future costs. Warranty costs are reflected in the Statement of Operations as a Cost of Sales. A reconciliation of the changes in the Company’s warranty liability is as follows (unaudited, in thousands):


	Three months ended					Nine months ended

	September 30, 2006			September 30, 2005		September 30, 2006			September 30, 2005

Balance at beginning of period	$	21		$	18	$	21		$	13
Accruals for warranties issued during the period		—			3		4			8

Actual warranty costs		(4	)		—		(8	)		—

Balance at end of period	$	17		$	21	$	17		$	21


	As permitted under California law, and under the provisions of the Company’s articles of incorporation and by-laws, the Company is obligated to indemnify its officers and directors for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The term of the indemnification period is for the officer’s or director’s lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has a director and officer insurance policy that limits our exposure and enables it to recover a portion of any future amounts paid. As a result of the Company’s insurance policy coverage, it believes that the estimated fair value of these indemnification agreements is insignificant.

	The Company enters into standard indemnification agreements with its customers in the ordinary course of business. Pursuant to these agreements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company’s business partners or customers, in connection with any U.S. patent, or any copyright or other intellectual property infringement claim by any third party with respect to the Company’s products. The term of these indemnification agreements is generally perpetual following execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has never incurred claims or costs to defend lawsuits or settle claims related to these indemnification agreements.

7.	Stock Buyback:

	In the third quarter of 2006, the Board of Directors of the Company authorized it, from time to time, to repurchase at market prices, up to $1 million worth of shares of its common stock for cash in open market, negotiated or block transactions. The timing of such transactions has depended and will depend on market conditions, other corporate strategies and has been and will be at the discretion of the Company’s management. No time limit was set for the completion of this program. At the time of the approval by its Board of Directors, the Company had approximately 4 million shares of common stock outstanding. As of October 31, 2006, the Company has repurchased from open market transactions a total of 11,000 shares for a total purchase price of $30,000, at an average per share price of $2.86. The Company intends to continue to execute its buyback program as the Company’s management deems advisable.

8.	Recent Accounting Pronouncements:

	In July 2006, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation Number 48, “Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109” (“FIN 48”). FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken in a tax return. The Company must determine whether it is “more-likely-than-not” that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the more-likely-than-not recognition threshold, the position is measured to determine the amount of benefit to recognize in the financial statements. FIN 48 applies to all tax positions related to income taxes subject to FASB Statement No. 109, “Accounting for Income Taxes.” The interpretation clearly scopes out income tax positions related to FASB Statement No. 5, “Accounting for Contingencies.” The Company will adopt the provisions of this statement beginning in the first quarter of 2007. The cumulative effect of applying the provisions of FIN 48, if any, will be reported as an adjustment to the opening balance of retained earnings on January 1, 2007. Management is in the process of determining the impact, if any, of the adoption of FIN 48.

	In September 2006, the SEC issued Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements” (“SAB 108”). SAB 108 was issued in order to eliminate the diversity of practice surrounding how public companies quantify financial statement misstatements. It requires quantification of financial statement misstatements based on the effects of the misstatements on each of the company’s financial statements and the related financial statement disclosures. The provisions of SAB 108 must be applied to annual financial statements no later than the first fiscal year ending after November 15, 2006. The Company does not anticipate that the application of SAB 108 will have a material effect on its financial position or results of operations.

SPECIAL NOTE ON FORWARD-LOOKING STATEMENTS

This document contains forward-looking statements that involve risks and uncertainties. Our operating results may vary significantly from quarter to quarter due to a variety of factors, including changes in our product and customer mix, constraints in our manufacturing and assembling operations, shortages or increases in the prices of raw materials and components, fluctuations in distribution partner inventory levels, changes in pricing policy by us or our competitors, a slowdown in the growth of the networking market, seasonality, timing of expenditures, and economic conditions in the United States, Europe and Asia. Words such as “believes,” “anticipates,” “expects,” “intends” and similar expressions are intended to identify forward-looking statements, but are not the exclusive means of identifying such statements. Unless the context otherwise requires, references in this Form 10-Q to “we,” “us,” or the “Company” refer to Castelle. Readers are cautioned that the forward-looking statements reflect management’s analysis only as of the date hereof, and we assume no obligation to update these statements. Actual events or results may differ materially from the results discussed in the forward-looking statements. Factors that might cause such a difference include, but are not limited to the risks and uncertainties discussed herein, as well as other risks set forth under Item 1A of Part II of this Form 10-Q below and in our Annual Report on Form 10-K for the year ended December 31, 2005.


ITEM 2.	MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Management’s Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements that are subject to many risks and uncertainties that could cause actual results to differ significantly from expectations. For more information on forward-looking statements, refer to the “Special Note on Forward-Looking Statements” prior to this section. The following discussion should be read in conjunction with the unaudited Condensed Consolidated Financial Statements and the Notes thereto included in Item 1 of this Quarterly Report on Form 10-Q and the audited Consolidated Financial Statements and the Notes thereto included in our Form 10-K for the year ended December 31, 2005.

Critical Accounting Policies

Our financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America. Preparing financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. These estimates and assumptions are affected by management’s application of accounting policies. Critical accounting policies for us include revenue recognition; distributor programs and incentives; credit, collection and allowances for doubtful accounts; inventories and related allowance for obsolete and excess inventory; and income taxes, which are discussed in more detail under the caption “Critical Accounting Policies” in our 2005 Annual Report on Form 10-K.

Net Sales
Products	$	1,762	$	1,946	$	5,556	$	5,955
Services		856		755		2,463		2,186

Total net sales	$	2,618	$	2,701	$	8,019	$	8,141


	Net sales for the third quarter of 2006 decreased 3% to $2.6 million from $2.7 million for the same period in 2005. Net sales for the first nine months of 2006 decreased 1% to $8.0 million from $8.1 million for the same period in 2005.

	Product sales for the third quarter of 2006 decreased 9% to $1.8 million from $1.9 million for the same period in 2005 mainly due to lower North American revenues resulting from lower demand for our fax server products. Product sales of $5.6 million for the first nine months of 2006 represent a 7% decrease from $6.0 million for the first nine months of 2005, mostly attributable to lower shipments of our products to our distribution partners due to their periodic adjustment of inventory levels during the second quarter of 2006.

	Service sales are comprised primarily of extended warranty and support programs as well as 60-days of maintenance bundled with initial product sales. Sales related to these arrangements are recognized ratably over the period of the arrangement. Service sales for the third quarter of 2006 increased 13% to $856,000 from $755,000 for the same period in 2005. For the first nine months of 2006, service sales increased 13% to $2.5 million from $2.2 million for the same period in 2005. The increase in service sales was primarily due to increased sales of extended warranty contracts due to an increase in our installed customer base.

	Sales by geographic area for the three and nine months ended September 30, 2006 and 2005 are summarized as follows (unaudited, in thousands):

	Three months ended				Nine months ended

	September 30, 2006		September 30, 2005		September 30, 2006		September 30, 2005

United States	$	2,285	$	2,335	$	6,942	$	6,390
Europe		106		116		417		588
Pacific Rim		149		140		465		716
Rest of Americas, excluding United States		78		110		195		447

Total Sales	$	2,618	$	2,701	$	8,019	$	8,141


	Sales in the United States for the third quarter of 2006 were $2.3 million, comparable to the sales in the same period in 2005, representing 87% and 86% of total net sales in the third quarter of 2006 and 2005, respectively. United States sales for the first nine months of 2006 were $6.9 million, as compared to $6.4 million for the same period in 2005, representing 87% and 78% of total net sales for the first nine months of 2006 and 2005, respectively. The increase in sales is mostly attributable to higher sales from services, offset in part by lower product shipments to the distribution channels.

	International sales (excluding sales to the rest of the Americas) for the third quarter of 2006 were $255,000 as compared to $256,000 for the same period in 2005, representing 10% and 9% of net sales for the third quarter of 2006 and 2005, respectively. International sales were $882,000 for the first nine months of 2006, as compared to $1,304,000 for the same period in 2005, representing 11% and 16% of total net sales for the first nine months of 2006 and 2005, respectively. The decrease in international sales during the nine month period ended September 30, 2006 was primarily due to a longer than anticipated lead time to evaluate our FaxPress Premier fax server products by our primary Pacific Rim integrator, resulting in a delay in orders for our fax server products.

	Sales to the rest of the Americas (excluding the United States) for the third quarter of 2006 were $78,000 as compared to $110,000 for the same period in 2005, representing 3% and 4% of total net sales for the third quarter of 2006 and 2005, respectively. For the nine months ended September 30, 2006 and 2005 sales to the rest of the Americas were $195,000 and $447,000, respectively, representing 2% and 5% of net sales for the first nine months of 2006 and 2005, respectively. Sales in the first nine months of 2005 included a shipment of FaxPress Premier server products to a certain customer in Latin America of $203,000.

	September 30, 2006			September 30, 2005			September 30, 2006			September 30, 2005

	(unaudited, dollar amounts in thousands)
Cost of sales:
Products	$	766		$	772		$	2,200		$	1,988
Services		248			250			800			778

Total cost of sales		1,014			1,022			3,000			2,766

Gross profit		1,604			1,679			5,019			5,375
Gross profit %		61	%		62	%		63	%		66	%


	Gross profit for the third quarter of 2006 and 2005 was $1.6 million and $1.7 million, respectively, or 61% and 62% of net sales for the third quarter of 2006 and 2005, respectively. Gross profit for the first nine months of 2006 and 2005 was $5.0 million and $5.4 million, respectively, or 63% and 66% of net sales for the first nine months of 2006 and 2005, respectively. The decrease in gross profit margins in the nine months ended September 30, 2006 as compared to the same periods in 2005 was primarily due to more FaxPress Premier fax server products sold at a higher average selling price than FaxPress fax server products. FaxPress Premier fax server products yield a lower gross profit percentage as compared to FaxPress fax server products.

	*Research & Development*

	Research and product development expenses for the third quarter of 2006 were $450,000, or 17% of net sales, as compared to $395,000, or 15% of net sales, for the same period in 2005. For the first nine months of 2006, research and development expenses were $1,366,000, or 17% of net sales, as compared to $1,252,000, or 15% of net sales for the same period of 2005. The increase in research and product development expenses of $55,000 for the third quarter of 2006 compared to the same period in 2005 is primarily due to share-based compensation expenses of $23,000. The increase of $113,000 over the nine month period was primarily due to share-based compensation expenses of $81,000. No share-based compensation expenses were incurred in fiscal 2005.

	*Sales & Marketing*

	Sales and marketing expenses for the third quarter of 2006 were $548,000, or 21% of net sales, as compared to $646,000, or 24% of net sales, for the same period in 2005. Sales and marketing expenses were $1.9 million for the first nine months of 2006, comparable to the same period of 2005, representing 24% and 23%, respectively, of net sales for these period. The decrease of $98,000 in sales and marketing expenses for the third quarter of 2006 compared to the same period in 2005 is primarily due to a $37,000 decrease in sales commissions earned, a decrease in consulting expenses of $35,000, and a decrease in trade show and travel related expenses of $23,000. The increase of $79,000 over the nine month period is mainly due to a $50,000 increase in sales commissions earned, and a $61,000 increase in expenses related to customer lead generation activities, offset by a decrease in consulting expenses of $16,000.

	*General & Administrative*

	General and administrative expenses were $443,000 for the third quarter of 2006 as compared to $416,000 for the same period in 2005, representing 17% and 15% of net sales of the third quarter of 2006 and 2005, respectively. The increase of $27,000 for the third quarter of 2006 compared to the same period in 2005 is primarily due to $27,000 in share-based compensation expense. For the first nine months of 2006, general and administrative expenses were $1.5 million, or 19% of net sales, as compared to $1.6 million, or 20% of net sales, for the first nine months of 2005. The decrease of $135,000 for the nine months ended September 30, 2006 is primarily due to $145,000 in accounting and legal fees incurred during the first nine months of 2005 related to the restatement of our historical financial statements, and a $61,000 decrease in employee bonuses, partially offset by $101,000 of share-based compensation expenses included in the first nine months of 2006. No share-based compensation expenses were incurred in fiscal 2006. General and administrative expenses are expected to increase in the fourth quarter of fiscal 2006 and during fiscal 2007 as we begin to prepare for Sarbanes-Oxley internal control compliance.

	*Provision for Income Tax*

	We account for income taxes in accordance with the liability method. Under the liability method, deferred assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between financial statement carrying amounts of assets and liabilities and their respective tax bases. The provision for income taxes is comprised of the current tax liability and the change in deferred tax assets and liabilities. We establish a valuation allowance to the extent that all or some portion of the deferred tax assets will not be recoverable against future taxable income.

	Significant management judgment is required in determining the provision for income taxes, and, in particular, any valuation allowance recorded against our deferred tax assets. During 2005, we again reviewed the need for a valuation allowance against our deferred tax assets. As a result of this review, we determined that, based on 2005 financial results and projected future taxable income, an increase in the valuation allowance was necessary. We recorded a tax provision in 2005 of $395,000 resulting from federal and state provision and an increase in the valuation allowance. Due to our continued operating profitability over 19 straight quarters and a determination that it is more likely than not that certain future tax benefits will be realized, a total of $1.1 million of our deferred tax assets has been recognized and was included on our consolidated balance sheet as of December 31, 2005. Based in large part on our projected future taxable income, we did not record income tax provision in the first three quarters of 2006. We will record a tax provision in future periods when all available net operating losses and tax credit carryforwards are fully utilized or the remaining deferred tax assets are deemed to be unrealizable.

	As of December 31, 2005, we had approximately $12.2 million and $1.8 million of net operating loss (“NOL”) carryforwards available to offset future federal and California taxable income, respectively. In addition, at December 31, 2005, we had federal and California credit carryforwards of approximately $1.3 million and $835,000, respectively. We do not expect to utilize significant amounts of cash for income tax payments until the NOLs have been utilized.

Liquidity and Capital Resources

Cash and cash equivalents	$	7,397	$	6,766
Working capital	$	7,426	$	6,784
Working capital ratio		3.7		3.6


	Since the initial public offering of our common stock in December 1995, our principal source of funding has been cash from our operations, with some funding from capital equipment lease lines. As of September 30, 2006, we had $7.4 million of cash and cash equivalents, an increase of $631,000 from December 31, 2005. The increase in cash and cash equivalents was primarily attributable to cash provided by operating activities of $752,000, offset by $138,000 in cash used in investing activities.

	Our operating activities generated cash of $752,000 in the first nine months of 2006 primarily due to our net income. Net cash used in investing activities of $138,000 over the nine month period ended September 30, 2006 was primarily used for the purchase of computer hardware and software which is in line with historical requirements.

	In the third quarter of 2006, our Board of Directors authorized us, from time to time, to repurchase at market prices, up to $1 million worth of shares of our common stock for cash in open market, negotiated or block transactions. The timing of such transactions has depended and will depend on market conditions, other corporate strategies and has been and will be at the discretion of our management. No time limit was set for the completion of this program. At the time of the approval by our Board of Directors, we had approximately 4 million shares of common stock outstanding. As of October 31, 2006, we have repurchased from open market transactions a total of 11,000 shares for $30,000, at an average per share price of $2.86. We intend to continue to execute our buyback program as our management deems advisable.

	We renewed our line of credit with Silicon Valley Bank in July 2006, which now matures on July 30, 2007. The revolving line of credit provides for borrowings of up to $6.0 million. Borrowings under this line of credit agreement are collateralized by all of our assets and bear interest at the bank’s prime rate plus 0.50%. We are required to maintain certain minimum cash and investment balances with the bank and meet certain other financial covenants. As of September 30, 2006, we have not drawn down on the line of credit and were in compliance with debt covenants and all other terms of the agreement.

	We lease certain of our equipment under various operating and capital leases that expire at various dates through 2006. The lease agreements frequently include renewal, escalation clauses and purchase provisions, and require us to pay taxes, insurance and maintenance costs. As of September 30, 2006, we have no long term debts related to these operating and capital leases.

	We lease our headquarters in Morgan Hill, California. We extended our building lease for a term of five years commencing on June 1, 2004 and expiring on May 31, 2009, with one conditional three-year renewal option, which if exercised, would extend the lease to May 31, 2012 commencing with rent at ninety-five percent of fair market value. As of September 30, 2006, future minimum payments under the lease were $552,000.

	The following represents combined aggregate maturities for all our financing and commitments as of September 30, 2006 (unaudited, in thousands):

	Payments Due by Period

Contractual Obligations	Total		1 Year		2 - 3 Years		4 - 5 Years		More than 5 Years

Capital (Finance) Lease Obligations	$	2	$	2		—		—		—

Operating Lease Obligations	$	552	$	207	$	345		—		—

Total contractual cash obligations	$	554	$	209	$	345		—		—


	In addition, because we are dependent on a small number of distributors for a significant portion of the revenues from our products, the loss of any of our major distributors or their inability to satisfy their payment obligations to us could have a significant adverse effect on our business, operating results and financial condition. In the first nine months of 2006, our two largest distributors collectively represented approximately 48% of our net sales, during the same period of 2005, our two largest distributors collectively represented approximately 45% of our net sales.

	We believe that, for the periods presented, inflation has not had a material effect on our operations.

Recent Accounting Pronouncements

	In July 2006, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation Number 48, “Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109” (“FIN 48”). FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken in a tax return.

The cumulative effect of applying the provisions of FIN 48, if any, will be reported as an adjustment to the opening balance of retained earnings on January 1, 2007. Management is in the process of determining the impact, if any, of the adoption of FIN 48.

	In September 2006, the SEC issued Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements” (“SAB 108”). SAB 108 was issued in order to eliminate the diversity of practice surrounding how public companies quantify financial statement misstatements. It requires quantification of financial statement misstatements based on the effects of the misstatements on each of the company’s financial statements and the related financial statement disclosures. The provisions of SAB 108 must be applied to annual financial statements no later than the first fiscal year ending after November 15, 2006. The Company does not anticipate that the application of SAB 108 will have a material effect on its financial position or results of operations.

	ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

	We had no holdings of derivative financial or commodity instruments at September 30, 2006. However, we are exposed to financial market risks, including changes in interest rates and foreign currency exchange rates. The fair value of our money market accounts and related income would not be significantly impacted by increases or decreases in interest rates due mainly to the highly liquid nature of these investments. Although sharp declines in interest rates could seriously harm interest earnings, such declines are not expected to materially affect our overall financial position, results of operations or cash flows. In addition, while much of our revenue is transacted in U.S. Dollars, certain spending is transacted in Pounds Sterling. These amounts are not currently material to our financial statements and, therefore, we believe that changes in foreign currency exchange rates should not materially affect our overall financial position, results of operations or cash flows.

	ITEM 4. CONTROLS AND PROCEDURES

	Evaluation of Disclosure Controls and Procedures

	Regulations under the Securities Exchange Act of 1934 require public companies, including our company, to maintain “disclosure controls and procedures,” which are defined to mean a company’s controls and other procedures that are designed to ensure that information required to be disclosed in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms and that such information is accumulated and communicated to the company’s management, including its chief executive officer and chief financial officer or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosures. Our Chief Executive Officer and our Chief Financial Officer, based on their evaluation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q, have concluded that our disclosure controls and procedures were, as of the end of such period, effective for this purpose.

	Changes in Internal Control Over Financial Reporting

	There have not been any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934) during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

	Limitations on Effectiveness of Controls

	In designing and evaluating our disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and our management necessarily applied its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
