Notes to Condensed Consolidated Financial Statements

(Unaudited)

Note 1. Summary of Significant Accounting Policies

Basis of Presentation

The financial information presented in this Form 10-Q is not audited and is not necessarily indicative of the future consolidated financial position, results of operations or cash flows of RAE Systems, Inc. (the “Company” or “RAE”). The unaudited financial statements contained in this Form 10-Q have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company’s financial position, results of operations and its cash flows for the stated periods, in conformity with the accounting principles generally accepted in the United States of America. The consolidated balances at December 31, 2005 were derived from the audited financial statements included in the Company’s Annual Report (“Annual Report”) on Form 10-K for the year ended December 31, 2005. The financial statements included in this report should be read in conjunction with the audited financial statements for the year ended December 31, 2005 included in the Annual Report.

Principles of Consolidation

The consolidated financial statements include the accounts of RAE Systems Inc. and its subsidiaries. The ownership of other interest holders of consolidated subsidiaries is reflected as minority interest. All significant intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

Revenue Recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectibility is reasonably assured. A provision for estimated product returns is established at the time of sale based upon historical return rates adjusted for current economic conditions. Historically, the Company has experienced an insignificant amount of sales returns. The Company recognizes revenue upon shipment to its distributors in accordance with standard contract terms that pass title of all goods upon delivery to a common carrier (FOB factory) and provides for sales returns under standard product warranty provisions. Revenues related to services performed under the Company’s extended warranty program represented less than 1% of net revenues in the first quarter of 2006 and 2005 and are recognized as earned based upon contract terms, generally ratable over the term of service. The Company recorded project installation work in China using the percentage-of-completion method. Installation revenue represented less than 4% of net revenue in the first quarter of 2006 and 2005. Net revenues include amounts billed to customers in sales transactions for shipping and handling, as prescribed by the Emerging Issues Task Force Issue (“EITF”) No. 00-10, Accounting for Shipping and Handling Fees and Costs. Shipping fees represented less than 1% of net revenues in the first quarter of 2006 and 2005. Shipping costs are included in cost of goods sold.

Earnings Per Share

Basic earnings per share includes no dilution and is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution of common stock equivalents such as options and warrants, to the extent the impact is dilutive. Anti-dilutive shares excluded from diluted earnings per share calculation for three month periods ended March 31, 2006 and 2005 were 2,864,353 and 4,424,741, respectively.

Stock Option Plan

In August 1993, the Company’s Board of Directors adopted the 1993 Stock Option Plan and in May 2002, the Board of Directors adopted the 2002 Stock Option Plan (collectively the “Plans”). The Plans authorize the grant of options to purchase shares of common stock to employees, directors, and consultants of the Company and its affiliates. The Plans feature both incentive and non-statutory options.

Incentive options may be granted at not less than 100% of the fair market value per share, and non-statutory options may be granted at not less than 85% of the fair market value per share at the date of grant as determined by the Board of Directors or committee thereof, except for options granted to a person owning greater than 10% of the outstanding stock, for which the exercise price must not be less than 110% of the fair market value. Options granted under the Plans generally vest 25% after one year with the remainder vesting monthly over the following three years and are exercisable over ten years.

As of March 31, 2006, the Company has reserved 268,226 shares of common stock for issuance under the 1993 Stock Option Plan and 2,336,967 shares of common stock for issuance under the 2002 Stock Option Plan. As of March 31, 2006, the Company had 1,680,534 shares of common stock available for future grant under the 2002 Stock Option Plan.

Non-Plan Stock Options

In 2002, the Company granted certain of its directors non-plan options to purchase 400,000 shares of non-plan restricted stock at a weighted-average exercise price of $0.985. The options vest 25% after one year with the remainder vesting monthly over the following three years and are exercisable over ten years. In 2004, the Company issued 63,000 shares of non-plan restricted stock due to the exercise of such options. As of March 31, 2006, the Company had 337,000 non-plan options outstanding with a weighted average exercise price of $1.02. As of March 31, 2006, 332,311 options were exercisable and had a remaining contractual life of six years.

Adoption of SFAS 123(R)

Effective January 1, 2003, the Company adopted FAS Statement No. 123, “Accounting for Stock-Based Compensation,” (“FAS 123”) for the recognition of stock-based compensation cost in its statement of operations. The fair value of each option award was estimated on the date of the grant using the Black-Scholes-Merton valuation method. This fair value was amortized as compensation expense, on a straight line basis, over the requisite service periods of the awards, which was generally the vesting period.

Effective January 1, 2006, the Company adopted the fair value recognition provisions of FAS No. 123 (Revised 2004), “Share-Based Payment,” (“FAS 123(R)”) where the fair value of each option is adjusted to reflect only those shares that are expected to vest. The company’s implementation of FAS 123(R) uses the modified-prospective-transition method where the compensation cost related to each unvested option as of January 1, 2006, is recalculated and any necessary adjustment is reported in the first quarter of adoption

The cumulative impact of estimating future forfeitures in the determination of period expense, rather than recording forfeitures when they occur as previously permitted requires the company to reverse $4,000 of compensation expense previously recognized. The cumulative benefit from the accounting change, net of tax, of $2,000 was recorded in the first quarter of 2006 and reflects the net cumulative impact of estimating future forfeitures.

Determining Fair Value

Valuation and amortization method —The Company estimates the fair value of stock options granted using the Black-Scholes-Merton option-pricing formula and a single option award approach. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period.

Expected Term —The Company’s expected term represents the period that the Company’s stock-based awards are expected to be outstanding and was determined using the “Simplified Method” as defined in the Securities and Exchange Commission’s Staff Accounting Bulletin No. 107.

Expected Volatility— The Company’s expected volatilities are based on historical volatility of the Company’s stock, adjusted where determined by management for unusual and non-representative stock price activity not expected to recur.

Expected Dividend —The Black-Scholes-Merton valuation model calls for a single expected dividend yield as an input. The Company currently pays no dividends and does not expect to pay dividends in the foreseeable future.

Risk-Free Interest Rate— The Company bases the risk-free interest rate on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term.

Estimated Forfeitures— When estimating forfeitures, the Company uses the average historical option forfeitures over a period of four years.

Fair Value —The fair value of the Company’s stock options granted to employees for the three months ended March 31, 2006 and March 31, 2005, was estimated using the following weighted- average assumptions:


	Three months ended
	March 31, 2006			March 31, 2005
Option Plan Shares
Expected Term in Years		6.08			5.00
Volatility		79.2	%		104.7	%
Expected Dividend		0	%		0	%
Risk-free interest rate		4.79	%		4.10	%
Weighted-average fair value	$	2.61		$	2.85

Stock Compensation Expense

Stock Compensation Expense —The Company recorded approximately $343,000 and $461,000 of stock-based compensation for the three months ended March 31, 2006 and March 31, 2005, respectively.

As required by FAS 123(R), management made an estimate of expected forfeitures and is recognizing compensation costs only for those equity awards expected to vest.

At March 31, 2006, the total unearned compensation cost related to unvested options granted to employees under the Company’s stock option plans but not yet recognized was approximately $2.6 million, net of estimated forfeitures of approximately $370,000. The Fair Value of each grant will be amortized on a straight-line basis over a weighted-average period of approximately 2.5 years and will be adjusted for subsequent changes in estimated forfeitures.

The Company issues new shares of common stock upon exercise of stock options. The following is a summary of option activity for the Company’s stock option plans, excluding non-vested shares:


Options	Shares		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Life	Aggregate Intrinsic Value
Outstanding at January 1, 2006	2,701,554		$	2.92
Granted	63,500			3.63
Exercised	(99,861	)		0.50
Forfeited or Expired	(60,000	)		4.53

Outstanding at March 31, 2006	2,605,193		$	2.99	7.48	$	3,095,250

Exercisable at March 31, 2006	1,649,513		$	2.34	6.90	$	2,786,803

The weighted-average grant-date fair value of options granted during the first three months of 2006 and 2005 were 2.61 and 2.85, respectively. The total intrinsic value of options exercised during the first three months of 2006 and 2005 were approximately $300,000 and $1.5 million, respectively.

Variable Interest Entities

RAE France was identified by management as a variable interest entity. The Company is the primary beneficiary through its ownership of RAE Europe ApS. RAE France distributes and sells RAE products exclusively in France. Total sales in the first quarter of 2006 and 2005 were $355,000 and $214,000, respectively. The Company has consolidated RAE France since December 2004.

Segment Reporting

The Company’s operating divisions consist of geographically-based entities in the Americas, China, the rest of Asia and Europe. All such operating divisions have similar economic characteristics, as defined in SFAS No. 131, Disclosures About Segments of an Enterprise and Related Information, and accordingly, we operated as one reportable segment for quarters ended March 31, 2006 and 2005.

Reclassification

Certain prior year amounts have been reclassified to conform to the current year presentation. These reclassifications have no effect on previously reported results of operations.

Note 3. Income Tax

The effective tax rate for the quarter ended March 31, 2006 was 12% of pretax loss, compared to 76% of pretax income in the first quarter of 2005. We calculated our income tax provisions based on the estimated annual effective tax rate for the Company. However, as required by FASB Interpretation 18, “Accounting for Income Taxes in Interim Periods” (“FIN 18”), the impact of items of tax expense (or benefit) that do not relate to “ordinary income” in the current year generally should be accounted for discretely in the period in which it occurs and be excluded from the effective tax rate calculation. As a result, the Company reported discrete tax benefits associated with release of valuation allowance of $60,000. Excluding this discrete item, our effective tax rate was 8% compared to 76% in 2005.

Additionally, in accordance with FIN 18, we excluded from the consolidated worldwide effective tax rate, computations in certain jurisdictions where no tax benefit of losses, either year-to-date or anticipated fiscal year, would be recognized. Accordingly, the tax benefit for the first quarter of 2006 excludes the benefit of losses in selected foreign jurisdictions in which the Company anticipates providing a full valuation allowance against the loss carry-forward. The effective tax rate is highly dependent upon the geographic distribution of our worldwide earnings or loss, tax regulations in each geographic region, the availability of tax credits and carry-forwards, and the effectiveness of our tax planning strategies. We regularly monitor the assumptions used in estimating our annual effective tax rate and adjust our estimates accordingly. If actual results differ from our estimates, future income tax expense could be materially affected.

The Internal Revenue Service (“IRS”) is currently auditing the Company’s federal income tax returns for the fiscal year ended December 31, 2003. Based on the results of the preliminary examination, the Company has paid $391,000 to the IRS in April 2006, which was accrued at December 31, 2005. Management believes the ultimate outcome of the IRS audit will not have a material adverse impact on the Company’s financial position or results of operations.

Note 5. Commitments and Contingencies

Legal Proceedings

From time to time, the Company is engaged in various legal proceedings incidental to its normal business activities. Although the results of litigation and claims cannot be predicted with certainty, the Company believes the final outcome of such matters will not have a material adverse effect on its financial position, results of operations or cash flows. A motion was filed on June 17, 2005, by Polimaster Ltd. and Na & SE Trading Co. Limited, for an injunction that would prevent RAE Systems from shipping its Gamma RAE II product and prohibiting RAE from making any additional sales of products in its possession licensed from Polimaster Ltd. and Na & SE Trading Co. Limited, pending resolution of arbitration between the parties. The motion was denied on September 6, 2005. While this claim may be subject to arbitration in accordance with the original contract between the parties, we do not expect it to have a material effect upon our business or results of operations.

Operating leases

The Company and its subsidiaries lease certain manufacturing, warehousing and other facilities under operating leases. The leases generally provide for the lessee to pay taxes, maintenance, insurance and certain other operating costs of the leased property. Total rent expense for the quarters ended March 31, 2006 and 2005 was $151,000 and $209,000, respectively. Future minimum lease payments for each of the next four years from 2006 through 2009 excluding the Sunnyvale, California abandoned building lease are $244,000, $39,000, $34,000 and $28,000, respectively.

In December 2004, the Company purchased the property located at 3775 North First Street in San Jose, California. The lease related to our previous headquarters in Sunnyvale, California had been written off as of the second quarter of 2005. The total loss on abandonment of the lease was approximately $2 million. Future discounted lease payments related to the Sunnyvale building have been included in accrued expenses totaling $472,000 and other long term liabilities totaling $1,357,000 at March 31, 2006. Future minimum lease payments for each of the next four years from 2006 through 2009 are $372,000, $528,000, $627,000 and $556,000, respectively. The discount rate used was 4.85%.

Purchase obligations

The Company has agreements with suppliers and other parties to purchase inventories and other goods and services. The Company estimated its non-cancelable obligations under these agreements in 2006, 2007, 2008, 2009 and 2010, to be approximately $6,625,000, $297,000, $163,000, $43,000 and $3,000 respectively. All non-cancelable obligations related to inventories are expected to be delivered within the next 12 months. The Company periodically reviews the carrying value of its inventories and non-cancelable purchase commitments by evaluating material usage requirements and forecasts and estimates inventory obsolescence, excess quantities and any expected losses on purchase commitments. The Company may record charges to write-down inventory due to excess, obsolete and slow-moving inventory and lower-of-cost or market based on an analysis of the impact of changes in technology, estimates of future sales volumes and market value estimates. There was no loss accrued related to current purchase obligations. However, any additional future write-down of inventories or loss accrued on inventory purchase commitments, if any, due to market condition, may negatively affect gross margins in future periods.

Guarantees

The Company is permitted under Delaware law and in accordance with its Bylaws to indemnify its officers and directors for certain events or occurrences, subject to certain limits, while the officer 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 amount of potential future indemnification is unlimited; however, the Company has a Director and Officer Insurance Policy that limits its exposure and enables it to recover a portion of any future amounts paid. As a result of our insurance policy coverage, the Company believes the fair value of these indemnification agreements is minimal.

In the Company’s sales agreements, the Company typically agrees to indemnify its customers for any expenses or liability resulting from claimed infringements of patents, trademarks or copyrights of third parties. The terms of these indemnification agreements are generally perpetual any time after execution of the agreement. The maximum amount of potential future indemnification is unlimited. To date, the Company has not paid any amounts to settle claims or defend lawsuits.

Note 6. Warranty Reserves

The Company generally provides a one to three year limited warranty on the majority of its products and establishes a provision for the estimated costs of fulfilling these warranty obligations at the time the related revenue is recorded. The following is a summary of the changes in these liabilities during the three-month periods ended March 31, 2006 and 2005:


	March 31,
	2006			2005
Provision for products sold during period	$	37,000			—
Adjustment of prior period provision	$	16,000			—
Claims paid during the period	$	(64,000	)	$	(73,000	)

Net decrease in liabilities	$	(11,000	)	$	(73,000	)

Balance beginning of period	$	377,000		$	490,000

Balance end of period	$	366,000		$	417,000

Note 7. Related Party Transactions

In conjunction with the KLH investment, an unsecured note payable was established for the previous KLH shareholders as part of the purchase price agreement. As of March 31, 2006 and December 31, 2005, $774,000 and $759,000, respectively, were included in notes payable – related parties and $836,000 and $821,000, respectively, were included in long term notes payable – related parties. The notes were non-interest bearing and were recorded at net present value using a discounted interest rate of 5.5%. A sum of $437,000 is due on demand after December 31, 2005. In addition, the future payment plan for each of the next four years from 2006 through 2009 is $400,000, $400,000, $250,000 and $250,000, respectively.

The Company has 36% ownership in Renex Technologies Ltd. (“Renex”) and pays a 7.5% royalty to Renex for using certain modems developed by Renex. In the first quarter of 2006 and 2005, the Company made royalty payments amounting to $14,000 and $0, respectively. In the first quarter of 2006 and 2005, the Company purchased $132,000 and $5,000, respectively, of inventory items from Renex and sold $32,000 and $19,000 of inventory items to Renex. Accounts receivable due from Renex at March 31, 2006 and December 31, 2005 were $100,000 and $84,000, respectively. The Company recorded $64,000 and $83,000 of equity in loss in unconsolidated affiliate in the first quarter of 2006 and 2005.

The Company’s Director of Information Systems, Lien Chen, is the wife of our Chief Executive Officer, Robert Chen. Ms. Chen was paid a salary of $26,000 and $22,000 for the quarters ended March 31, 2006 and 2005, respectively. Ms. Chen also receives standard employee benefits offered to all other full-time U.S. employees. Ms. Chen does not report to Robert Chen and compensation decisions, regarding Ms. Chen, are performed in the same manner as other U.S. employees with Robert Chen the final approval signatory on compensation recommendations.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements. In some cases, readers can identify forward-looking statements by terminology such as “may,” “will,” “should,” “could,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” or “continue.” These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from those stated herein. Although management believes that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, performance, or achievements. For further information, refer to the sections entitled “Factors That May

Affect Future Results” and “Risk Factors” in this Form 10-Q. The following discussion should be read in conjunction with the condensed consolidated financial statements and the notes thereto included elsewhere in this Form 10-Q.

Overview

We are a leading global developer and manufacturer of rapidly-deployable, multi-sensor chemical detection monitors and networks for homeland security and industrial applications. In addition, we offer a full line of portable single-sensor chemical and radiation detection products. We were founded in 1991 to develop technologies for the detection and early warning of hazardous materials. The market for our products has evolved from being strictly focused on environmental and industrial monitoring to now encompassing public safety and the threat of terrorism.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 revenue and expenses during the reporting period. On an on-going basis, we evaluate the estimates, including those related to our allowance for doubtful accounts, valuation of goodwill and intangible assets, valuation of deferred tax assets, restructuring costs, contingencies, inventory valuation, warranty accrual and the stock compensation expense. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ significantly from these estimates under different assumptions or conditions.

Revenue Recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectibility is reasonably assured. A provision for estimated product returns is established at the time of sale based upon historical return rates adjusted for current economic conditions. Historically, the Company has experienced an insignificant amount of sales returns. The Company recognizes revenue upon shipment to its distributors in accordance with standard contract terms that pass title of all goods upon delivery to a common carrier (FOB factory) and provides for sales returns under standard product warranty provisions. Revenues related to services performed under the Company’s extended warranty program represented less than 1% of net revenues in the first quarter of 2006 and 2005 and are recognized as earned based upon contract terms, generally ratable over the term of service. The Company recorded project installation work in China using the percentage-of-completion method. Installation revenue represented less than 4% of net revenue in the first quarter of 2006 and 2005. Net revenues include amounts billed to customers in sales transactions for shipping and handling, as prescribed by the Emerging Issues Task Force Issue (“EITF”) No. 00-10, Accounting for Shipping and Handling Fees and Costs. Shipping fees represented less than 1% of net revenues in the first quarter of 2006 and 2005. Shipping costs are included in cost of goods sold.

Accounts Receivable, Trade Notes Receivable and Allowance for Doubtful Accounts

The Company grants credit to its customers after undertaking an investigation of credit risk for all significant amounts. An allowance for doubtful accounts is provided for estimated credit losses at a level deemed appropriate to adequately provide for known and inherent risks related to such amounts. The allowance is based on reviews of loss, adjustments history, current economic conditions and other factors that deserve recognition in estimating potential losses. The Company generally does not require collateral for sales on credit. While management uses the best information available in making its determination, the ultimate recovery of recorded accounts receivable is also dependent upon future economic and other conditions that may be beyond management’s control. If there was a deterioration of a major customer’s credit-worthiness or if actual defaults were higher than what we have experienced historically, additional allowances would be required.

Trade notes receivables are presented to the Company from some of our customers in China as a payment against the outstanding trade receivables. These notes receivables are bank guarantee promissory notes which are non-interest bearing and generally mature within 6 months.

Inventories

Inventories are stated at the lower-of-cost, using the first-in, first-out method, or market. The Company is exposed to a number of economic and industry factors that could result in portions of its inventory becoming either obsolete or in excess of anticipated usage, or saleable only for amounts that are less than their carrying amounts. These factors include, but are not limited to, technological changes in the market, competitive pressures in products and prices, and the availability of key components from its suppliers. The Company has established inventory reserves when conditions exist that suggest that its inventory may be in excess of anticipated demand or is obsolete based upon assumptions about future demand for its products and market conditions. When recorded, reserves are intended to reduce the carrying value of the inventory to its net realizable value. If actual demand for specific products deteriorates, or market conditions are less favorable than those projected, additional reserves may be required.

Stock-based Compensation Expense

Determining Fair Value

Expected Term — The Company’s expected term represents the period that the Company’s stock-based awards are expected to be outstanding and was determined using the “Simplified Method” as defined in the Securities and Exchange Commission’s Staff Accounting Bulletin No. 107.

Expected Volatility — The Company’s expected volatilities are based on historical volatility of the Company’s stock, adjusted where determined by management for unusual and non-representative stock price activity not expected to recur.

Expected Dividend — The Black-Scholes-Merton valuation model calls for a single expected dividend yield as an input. The Company currently pays no dividends and does not expect to pay dividends in the foreseeable future.

Risk-Free Interest Rate — The Company bases the risk-free interest rate on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term.

Estimated Forfeitures — When estimating forfeitures, the Company uses the average historical option forfeitures over a period of four years.

Results of Operations

Three Months ended March 31, 2006 compared to the three Months ended March 31, 2005

Total Net Sales


	Three months ended March 31,
	2006		2005		Change		% change
Net sales	$	12,426,000	$	12,248,000	$	178,000	1	%

Net sales for the quarter ended March 31, 2006, increased by $178,000 (1%) over the same quarter in 2005. Net Sales for the quarter ended March 31, 2006, increased in Asia by $531,000 (17%) and Europe by $524,000 (34%) over the same period in 2005. The increases in Asia and Europe were primarily the result of increased sales of our products to the industrial sector in Asia and increased sales of our wireless systems in Europe. Net Sales in the Americas decreased by $878,000 (12%) primarily due to a large order delivered to the U.S. government during the first quarter of 2005 ($1.1 million) partially offset by increased sales in other areas.

Cost of Sales & Gross Margin


	Three months ended March 31,
	2006			2005			Change			% change
Cost of good sold	$	5,716,000		$	5,078,000		$	638,000		13	%
Gross profit	$	6,710,000		$	7,170,000		$	(460,000	)	-6	%
Gross profit as % of net sales		54	%		59	%

Cost of goods sold for the quarter ended March 31, 2006, increased by $638,000 (13%) over the same quarter in 2005. The increase in cost of goods sold was primarily due to a shift in sales in the Americas towards lower-margin portable products and increases in lower margin KLH installation and distributor products. In addition, KLH , with inherently lower margins on its distribution business, increased as a percentage of overall sales in the first quarter of 2006 versus the first quarter of 2005.

Sales and Marketing Expense


	Three months ended March 31,
	2006			2005			Change		% change
Sales and marketing	$	4,071,000		$	3,424,000		$	647,000	19	%
As % of net sales		33	%		28	%

Sales and marketing expenses increased by approximately $647,000 (19%) for the first quarter of 2006 over the same quarter in 2005. The increase in sales and marketing expense was primarily due to additional expenses in Asia of approximately $630,000. Of that total expense increase, approximately $510,000 was for additional sales people at KLH to support future growth and approximately $120,000 was increased expenses to support sales growth of RAE Systems products to Asian countries outside of China. Additionally, approximately $100,000 of increased European expense for the first quarter of 2006 was largely offset by decreases in the Americas for the same period.

Research and Development Expense


	Three months ended March 31,
	2006			2005			Change		% change
Research and development	$	1,273,000		$	1,097,000		$	176,000	16	%
As % of net sales		10	%		9	%

Research and development expenses increased by approximately $176,000 (16%) during the first quarter of 2006 over the first quarter of 2005. These additional expenses were primarily the result of $119,000 of increased expenses in Shanghai to support the development of portable and wireless products and $76,000 of increased expenses were to support other product improvements and development, including the fixed systems developed by KLH.

General and Administrative Expense


	Three months ended March 31,
	2006			2005			Change		% change
General and administrative	$	2,969,000		$	2,455,000		$	514,000	21	%
As % of net sales		24	%		20	%

General and administrative expenses increased by $514,000 (21%) in the first quarter 2006 over the same period during 2005. The increase was primarily related to expenses in the Americas and Shanghai of approximately $375,000 and $130,000, respectively. The additional expenses for the first quarter of 2006 versus the first quarter of 2005 in the Americas included $149,000 of consulting fees related to several human resource and accounting projects, $130,000 of professional fees related to Sarbanes-Oxley compliance, $50,000 of increased travel and $40,000 of professional recruiting fees. The increased expense in Shanghai was primarily the result of increased salary and benefits of approximately $50,000, increased depreciation of approximately $40,000 and generally higher operating expenses of $40,000 across the Shanghai G&A organization.

Other Income (Expense)


	Three months ended March 31,
	2006			2005			Change		% change
Interest income	$	174,000		$	99,000		$	75,000	76	%
Interest expense	$	(21,000	)	$	(33,000	)	$	12,000	-36	%
Other, net	$	24,000		$	(37,000	)	$	61,000	-165	%
Equity in loss of unconsolidated affiliate	$	(64,000	)	$	(83,000	)	$	19,000	-23	%

Total	$	113,000		$	(54,000	)	$	167,000	-309	%

As % of net sales		1	%		0	%

For the quarter ended March 31, 2006, total other income (expense) was $113,000 in income compared to $54,000 of expense in the same quarter in 2005. The increase in interest income of $75,000 was largely due to a higher rate of return on investments from generally higher interest rates in the first quarter of 2006 as compared to the first quarter of 2005. Other, net increased by $61,000 in the first quarter of 2006 versus the same quarter in 2005 resulting in a $24,000 gain versus a $37,000 loss. The gain in the first quarter of 2006 was mainly from the impact of increases to the Eurodollar and Renminbi relative to U.S. dollar obligations in our European and China operations, where the Eurodollar and the Renminbi are the functional currencies. In the first quarter of 2005, decreases to the Eurodollar relative to U.S. dollar obligations were the primary reason for the loss in Other, net.

Income Taxes


	Three months ended March 31,
	2006			2005			Change			% change
Income tax (benefit) / expense	$	(179,000	)	$	106,000		$	(285,000	)	-269	%
As % of (loss) income before income taxes, minority interest and cumulative effect on change in accounting principle		12	%		76	%

The tax benefit for the quarter ended March 31, 2006 was $179,000 or 12% of the loss before income taxes, minority interest and the cumulative effect on change in accounting principle, compared to $106,000 or 76% of the tax expense before income taxes and minority interest in the same quarter of 2005. Income tax provisions were calculated based on the estimated annual effective tax rate for the Company. The tax benefit for the first quarter of 2006 was lower than the US statutory rate because we excluded the benefit of losses in selected foreign jurisdictions in which the Company anticipates providing a full valuation allowance against the loss carry-forward. The high rate in 2005 was a result of permanent differences from the amortization of intangibles and losses in unconsolidated equity interests.

Minority interest in loss of consolidated entities


	Three months ended March 31,
	2006			2005			Change		% change
Minority interest in loss of consolidated subsidiaries	$	276,000		$	60,000		$	216,000	360	%
As % of net sales		2	%		0	%

For the quarter ended March 31, 2006, we recognized $276,000 in net loss allocated to minority interests consisting of the 36% minority interest’s share in KLH and our 51% majority investor’s share in the net income of RAE France. During the same quarter of 2005, we recognized $60,000 in net loss for the same investments.

Net Income


	Three months ended March 31,
	2006			2005		Change
Net (Loss) Income	$	(1,033,000	)	$	94,000	$	(1,127,000	)

The Net Loss for the quarter ended March 31, 2006 was $896,000. For the same period in 2005, we had net income of $94,000. The main reasons for the $990,000 decrease in net income were due to decreases in gross margin associated with a shift in the Americas towards lower margin portable products and increases in lower margin KLH installation an distributor products and increases in operating expenses associated with the growth of our infrastructure.

Cumulative Effect of Change in Accounting Principle


	Three months ended March 31,
	2006		2005	Change
Cumulative effect of change in accounting principle, net of tax effects	$	2,000	—	$	2,000

In conjunction with the adoption of FAS 123(R) in the first quarter of 2006, the Company recognized a cumulative benefit from accounting change of $4,000, net of tax effects of $2,000. This reflected the net cumulative impact, net of tax, of estimating future forfeitures in the determination of period expense, rather than recording forfeitures when they occur as previously permitted.

Liquidity and Capital Resources


	Quarter Ended March 31,
	2006			2005
Net cash provided by (used in):
Operating activities	$	(740,000	)	$	88,000
Investing activities	$	(2,041,000	)	$	(3,068,000	)
Financing activities	$	50,000		$	302,000
Effect of exchange rate changes on cash and cash equivalents	$	14,000		$	(80,000	)

Net (decrease) in cash and cash equivalents	$	(2,717,000	)	$	(2,758,000	)

To date, we have financed our operations primarily through bank borrowings, income from operations and proceeds from the issuances of equity securities. As of March 31, 2006, we had $28.3 million in cash and investments compared with $29.5 million as of December 31 2005. At March 31, 2006, we had $40.7 million of working capital (current assets less current liabilities) and had a current ratio (current assets divided by current liabilities) of 4.1 to 1.0. That compares with $41.4 million of working capital and a current ratio of 3.9 to 1.0 at December 31, 2005.

We have two lines of credit available for future growth expansion, which in the aggregate total $10 million. In October 2005, we secured a $5 million line of credit based on the prime-lending rate and a $5 million line of credit based on a fixed rate of 5.3%. Both lines expire in October 2006. We are currently in compliance with the debt covenants, and as such, have these lines available to us in full. At present, there are no amounts outstanding under these agreements.

Net cash used by operating activities for the quarter ended March 31, 2006, was $740,000, as compared with net cash provided by operating activities of $88,000 for the quarter ended March 31, 2005. The $828,000 reduction to operating cash flows for the quarter-ended March 31, 2006 versus the quarter-ended March 31, 2005 was primarily due to decreased profitability after adjusting for non-cash items ($755,000) and a larger reduction in liabilities ($1.4 million), partially offset by a larger reduction to assets ($1.3 million) versus the first quarter of 2005. The change in liabilities was mainly from lower accounts payable ($526,000), deferred revenues ($499,000) and accrued expenses ($340,000) as a result of a seasonal reduction in business volume from fourth quarter 2005 levels. The impact of lower asset levels was primarily from reductions to accounts receivables ($2.6 million) as a result of lower seasonal sales volumes compared with the fourth quarter of 2005. Partially offsetting the accounts receivable reduction was an increase in inventories ($1.1 million), mainly in our China selling and manufacturing operations as well as our European operations.

Net cash used in investing activities for the quarter-ended March 31, 2006, was $2.0 million as compared with $3.1 million for the quarter-ended March 31, 2005. Cash used in investing activities consisted of an increase in short term investments of $1.5 million in the first quarter of 2006 and $2.2 million in the first quarter of 2005 as in both quarters, we increased our short-term investments and reduced cash balances. Acquisition of property was $910,000 and $529,000 for the first quarter of 2005 and first quarter of 2006, respectively, as we continued to make investments in our infrastructure to support our growth and productivity initiatives.

Net cash provided by financing activities was $302,000 and $50,000 for the first quarter of 2005 and the first quarter of 2006 respectively as a result of exercises of stock options and, in the first quarter of 2005, also from an increase to notes payable in our China operations of $177,000.

We believe that our existing balances of cash and cash equivalents, together with cash generated from product sales, will be sufficient to meet our cash needs for working capital and capital expenditures for at least the next twelve months. Our future capital requirements will depend on many factors that are difficult to predict, including the size, timing and structure of any future acquisitions, future capital investments, and future results of operations. Any future financing we may require may be unavailable on favorable terms, if at all. Any difficulty in obtaining additional financial resources could force us to curtail our operations or could prevent us from pursuing our growth strategy. Any future funding may dilute the ownership of our stockholders.

Contractual Obligations

We lease certain manufacturing, warehousing and other facilities under operating leases expiring in various years through 2009. The leases generally provide for the lessee to pay taxes, maintenance, insurance, and certain other operating costs of the leased property. The following table quantifies our known contractual obligations as of March 31, 2006:


	Total		2006 (remaining 9 months)		2007		2008		2009		2010
Operating lease obligations	$	2,428,000	$	616,000	$	567,000	$	661,000	$	584,000
Open purchase orders	$	6,272,000	$	6,252,000	$	17,000	$	3,000
Notes payable - related parties	$	1,737,000	$	837,000	$	400,000	$	250,000	$	250,000
Other liabilities	$	859,000	$	373,000	$	280,000	$	160,000	$	43,000	$	3,000

Total	$	11,296,000	$	8,078,000	$	1,264,000	$	1,074,000	$	877,000	$	3,000

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The following discussion analyzes our disclosure to market risk related to concentration of credit risk, changes in interest rates and foreign currency exchange rates.

Concentration of Credit Risk

Currently, we have cash and cash equivalents deposited with two large United States financial institutions, one large Hong Kong financial institution, two large Shanghai financial institutions, two local Beijing financial institutions, and one large Danish financial institution. Our deposits generally exceed the amount of insurance available to cover such deposits. To date, we have not experienced any losses of deposits of cash and cash equivalents. Management regularly reviews our deposit amounts and the credit worthiness of the financial institution which hold our deposits.

Interest Rate Risk

As of March 31, 2006, we had cash and investments of $28.3 million consisting largely of cash and highly liquid short-term investments. The impact of interest rate fluctuations was immaterial. Changes to interest rates over time may, however, reduce or increase our interest income from our short-term investments. If, for example, there is a hypothetical 150 basis points change in the interest rates in the United States, the approximate impact on our cash and short-term investments would be +/- $180,000.

Foreign Currency Exchange Rate Risk

For the first quarter of 2006, a substantial portion of our recognized revenue has been denominated in United States dollars generated primarily from customers in the Americas (54%). Revenue generated from our European operations (17%) is primarily in euros, revenue generated by our China operations (26%) is in the local currency, the Renminbi (“RMB”) and revenue generated from our Hong Kong-based operations (3%) is in both Hong Kong dollars and United States dollars. We manufacture a majority of our component parts at our manufacturing facility in Shanghai, China. Our operations in China were largely unaffected by currency fluctuations until the July 2005 approximately 2.1% appreciation of the RMB relative to the United States dollar.

Our strategy has been and will continue to be to increase our overseas manufacturing and research and development activities to capitalize on low-cost intellectual property and efficiency in supply-chain management. In 2004, we made a strategic investment in China with the acquisition of a 64% interest in KLH, a Beijing-based manufacturer and distributor of environmental safety and security equipment. There has been continued speculation in the financial press that China’s currency, the RMB, will be subject to a further market adjustment relative to the United States dollar and other currencies. If, for example, there is a hypothetical 10% change in the RMB relative to the United States dollar, the approximate impact on our profits would be +/-$430,000 for a year. Were the currencies in all other countries in Europe and Asia where we have operations to change in unison with the RMB by a hypothetical 10% against the U.S. dollar, the approximate impact on our profits would be approximately +/-$250,000 for a year. The expected reduction in the total impact as against an RMB only appreciation is because some of the impact of the RMB change would be offset by changes to reported sales net of expenses in our other units as a result of changes in those countries’ functional currencies.

Furthermore, to the extent that we engage in international sales denominated in United States dollars in countries other than China, any fluctuation in the value of the U.S. dollar relative to foreign currencies could affect our competitive position in the international markets. Although we would continue to monitor our exposure to currency fluctuations and, when appropriate, may use financial hedging techniques in the future to minimize the effect of these fluctuations, we cannot be certain that exchange rate fluctuations will not adversely affect our financial results in the future.

Factors That May Affect Future Results

You should carefully consider the risks described below before making a decision regarding an investment in our common stock. If any of the following risks actually occur, our business could be harmed, the trading price of our common stock could decline and you may lose all or part of your investment. You should also refer to the other information contained in this report, including our financial statements and the related notes.

Our future revenues are unpredictable, our operating results are likely to fluctuate from quarter to quarter, and if we fail to meet the expectations of securities analysts or investors, our stock price could decline significantly.

Our quarterly and annual operating results have fluctuated in the past and are likely to fluctuate significantly in the future due to a variety of factors, some of which are outside of our control. Accordingly, we believe that period-to-period comparisons of our results of operations are not meaningful and should not be relied upon as indications of future performance. Some of the factors that could cause our quarterly or annual operating results to fluctuate include significant shortfalls in revenue relative to our planned expenditures, changes in budget allocations by the federal government for homeland security purposes, market acceptance of our products, ongoing product development and production, competitive pressures and customer retention.

It is likely that in some future quarters our operating results may fall below the expectations of investors. In this event, the trading price of our common stock could significantly decline.

We were unprofitable for the first quarter of 2006 and we may not be profitable in the future. If we continue to report losses or are marginally profitable, the financial impact of future events may be magnified and may lead to a disproportionate impact on the trading price of our stock.

We experienced a net loss for the quarter ended March 31, 2006, of $896,000 and reported a net profit of $91,000 for the fourth quarter of 2005. While we were profitable for three of the last five years, there can be no assurance when or if we will return to profitability. In addition, our financial results have historically bordered on profitability, with our results over the last twelve quarters ranging from $1.3 million quarterly loss to a $1.0 million quarterly profit, and if we continue to border on profitability, the financial impact may be magnified. For example, for a company with more considerable income or losses, a $250,000 impact may not be significant, whereas $250,000 in additional net loss would have increased our loss for the quarter ended March 31, 2006, by 28%. If we continue to border on profitability, any particular financial event could result in a relatively large change in our financial results or could be the difference between us having a profit or a loss for the particular quarter in which it occurs. Because the impact of any such events may be magnified, we may experience a disproportionate impact on our trading price as a result.

The market for gas and radiation detection monitoring devices is highly competitive, and if we cannot compete effectively, our business may be harmed.

The market for gas and radiation detection monitoring devices is highly competitive. Competitors in the gas and radiation monitoring industry differentiate themselves on the basis of their technology, quality of product and service offerings, cost and time to market. Our primary competitors in the gas detection market include Industrial Scientific Corporation, Mine Safety Appliances Company, BW Technologies, Ion Science, Draeger Safety Inc., Gastec Corporation and Bacou-Dalloz Group. Our competitors in the radiation market include TSA Limited, Polimaster, Exporanium and Santa Barbara Systems. Several of our competitors such as Mine Safety Appliances Company and Draeger Safety Inc. have longer operating histories, larger customer bases, greater brand recognition and significantly greater financial and marketing resources than we do. In addition, some of our competitors may be able to:

•

devote greater resources to marketing and promotional campaigns,

•

adopt more aggressive pricing policies or

•

devote more resources to technology and systems development.

In light of these factors, we may be unable to compete successfully.

We might not be successful in the development or introduction of new products and services in a timely and effective manner and, consequently, we may not be able to remain competitive and the results of operations may suffer.

Our revenue growth is dependent on the timely introduction of new products to market. We may be unsuccessful in identifying new product and service opportunities or in developing or marketing new products and services in a timely or cost-effective manner. In addition, while our current technology enables us to create products targeted to address the evolving market, we are unable to foresee whether we will continue to have the necessary technology in the future. In developing new products, we may be required to make significant investments before we can determine the commercial viability of the new product. If we fail to accurately foresee our customers’ needs and future activities, we may invest heavily in research and development of products that do not lead to significant sales.

We have expanded our current business of providing gas detection instruments to include radiation detection and wireless systems for local and remote security monitoring. While we perceive a large market for such products, the radiation detection and wireless systems markets are still evolving, and we have little basis to assess the demand for these products and services or to evaluate whether our products and services will be accepted by the market. If our radiation detection products and wireless products and services do not gain broad market acceptance or if we do not continue to maintain the necessary technology, our business and results of operations will be harmed.

In addition, compliance with safety regulations, specifically the need to obtain regulatory approvals in certain jurisdictions, could delay the introduction of new products by us. As a result, we may experience delays in realizing revenues from our new products.

Recently enacted changes in the securities laws and regulations have and are likely to continue to increase our costs.

The Sarbanes-Oxley Act of 2002 has required changes in some of our corporate governance, securities disclosure and compliance practices. In response to the requirements of that Act, the Securities Exchange Commission (“SEC”) and American Stock Exchange (“AMEX”) have promulgated new rules.

Compliance with these new rules has increased our legal, financial and accounting costs, and we expect these increased costs to continue indefinitely. We also expect these developments to make it more difficult and more expensive for us to obtain director and officer liability insurance and we may be forced to accept reduced coverage or incur substantially higher costs to maintain or obtain coverage. In addition, these developments may make it more difficult for us to attract and retain qualified members of our board of directors or qualified executive officers.

In the event we are unable to satisfy regulatory requirements relating to internal control over financial reporting or, if these controls are not effective, our business and financial results may suffer.

In designing and evaluating our internal control over financial reporting, we recognize that any internal control or procedure, no matter how well designed and operated, can provide only reasonable assurance of achieving desired control objectives. For example, a company’s operations may change over time as the result of new or discontinued lines of business and management must periodically modify a company’s internal controls and procedures to timely match these changes in its business. In addition, management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures and company personnel are required to use judgment in their application. While we continue to improve upon our internal control over financial reporting so that it can provide reasonable assurance of achieving its control objectives, no system of internal controls can be designed to provide absolute assurance of effectiveness.

In connection with year-end work on our fiscal year 2005 Form 10-K, management identified three material weaknesses in our internal control over financial reporting. The weaknesses were related to (i) inadequate control over our accounting and reporting of certain non-routine transactions occurring at two of our foreign operations, (ii) inadequate control over our accounting for stock-based compensation under SFAS 123, Accounting for Stock-Based Compensation, and (iii) an inadequate number of accounting and finance personnel or consultants sufficiently trained to address some of the complex accounting and financial reporting matters that arise from time-to-time. A discussion of the material weaknesses in our internal control over financial reporting and management’s remediation efforts is available herein under Item 4, “Controls and Procedures.”

Material weaknesses in internal control over financial reporting may materially impact our reported financial results and the market price of our stock could significantly decline. Additionally, adverse publicity related to a material failure of internal control over financial reporting could have a negative impact on our reputation and business.

If our new enterprise resource planning software is not implemented correctly, it could cause errors in our financial reporting or unexpected business interruptions.

During July 2005, we began implementing a new company-wide Enterprise Resource Planning (“ERP”) system to mitigate the risk of future deficiencies and strengthen our procedures for internal control over financial reporting. During the implementation period, which we expect to be completed before the end of the second quarter of 2006, we are at a higher risk while we configure the software, redesign some of our processes and train our personnel in the new software. While we expect that the design and operation of our new ERP system will help us improve our internal control over financial reporting, there can be no assurance that we will not have a future error in our financial statements. Such an error, if material, could require their restatement, having adverse effects on our stock price, potentially causing additional expense and limiting our access to financial markets. Moreover, ERP implementations are challenging initiatives that carry substantial project risk including the risk of unexpected business interruptions. Failure to properly implement the new information technology system could have an adverse impact on our operating results.

Future changes in accounting and taxation standards or practices can have a significant effect on our reported results.

A change in accounting standards or practices or a change in existing taxation rules or practices can have a significant effect on our reported results and may even affect our reporting of transactions completed before the change is effective. New accounting pronouncements and taxation rules and varying interpretations of accounting pronouncements and taxation practice have occurred and may occur in the future. Changes to existing rules or the questioning of current practices may adversely affect our reported financial results or the way we conduct business.

We are subject to risks and uncertainties of the government marketplace, including the risk that the government may not fund projects that our products are designed to address and that certain terms of our contracts with government agencies may subject us to adverse government actions or penalties.

Our business is increasingly dependent upon government funded projects. Decisions on what types of projects are to be funded by local, state and federal government agencies will have a material impact on our business. The current Federal budget for the Department of Homeland Security, which we refer to as “Homeland Security” herein, is a source for funding for many of our customers either directly or through grants to state and local agencies. The current Homeland Security budget increased by approximately 5% from $38.4 billion in fiscal year 2005 to $40.3 billion for fiscal year 2006. However, if the government does not fund projects that our products are designed to address, or funds such projects at levels lower than we expect, our business and results of operations will be harmed.

Government contracts also contain provisions and are subject to laws and regulations that provide government clients with rights and remedies not typically found in commercial contracts. For example, a portion of our federal contracting is done through the Federal Supply Schedules from the U.S. General Services Administration (“GSA”). Our GSA Schedule contract, like all others, includes a clause known as the “Price Reductions” clause; the terms of that clause are similar but not identical to a “most favored customer” clause in commercial contracts. Under that clause, we have agreed that the prices to the government under the GSA Schedules contract will maintain a constant relationship to the prices charged to certain commercial customers, i.e., when prices to those benchmark customers drop, so too must our prices on our GSA Schedules contract. Although we have undertaken extensive efforts to comply with the Price Reductions clause, it is possible that we, through, for example, an unreported discount offered to a “Basis of Award” customer, might fail to honor the obligations of the Price Reductions clause. If that occurred, we could, under certain circumstances, be subject to an audit, an action in fraud, or other adverse government actions or penalties.

We may not be successful in promoting and developing our brand, which could prevent us from remaining competitive.

We believe that our future success will depend on our ability to maintain and strengthen the RAE brand, which will depend, in turn, largely on the success of our marketing efforts and ability to provide our customers with high-quality products. If we fail to successfully promote and maintain our brand, or incur excessive expenses in attempting to promote and maintain our brand, our business will be harmed.

We face risks from our substantial international operations and sales.

We have significant operations in foreign countries, including manufacturing facilities, sales personnel and customer support operations. For the fiscal years ended December 31, 2004 and 2005, approximately 24% and 33% of our revenues, respectively, were from sales to customers located in Asia and approximately 10% and 11% of our revenues, respectively, were from sales to customers located in

Europe. For fiscal years ended December 31, 2004 and 2005, approximately 20% and 30%, of our revenues, respectively, were from sales in China through our KLH subsidiary. We have manufacturing facilities in China and in the United States. A significant portion of our products and components are manufactured at our facility in Shanghai, China.

Our international operations are subject to economic and other risks inherent in doing business in foreign countries, including the following:

•

difficulties with staffing and managing international operations;

•

transportation and supply chain disruptions and increased transportation expense as a result of epidemics, terrorist activity, acts of war or hostility, generally higher oil prices, increased security and less developed infrastructure;

•

economic slowdown and/or downturn in foreign markets;

•

international currency fluctuations;

•

political and economic uncertainty caused by epidemics, terrorism or acts of war or hostility;

•

legislative and regulatory responses to terrorist activity such as increased restrictions on cross-border movement of products and technology;

•

legislative, regulatory, police, or civil responses to epidemics or other outbreaks of infectious diseases such as quarantines, factory closures, or increased restrictions on transportation or travel;

•

increased costs and complexities associated with complying with Section 404 of the Sarbanes-Oxley Act of 2002;

•

general strikes or other disruptions in working conditions;

•

labor shortages;

•

political instability;

•

changes in tariffs;

•

generally longer periods to collect receivables;

•

unexpected legislative or regulatory requirements;

•

reduced protection for intellectual property rights in some countries;

•

significant unexpected duties or taxes or other adverse tax consequences;

•

difficulty in obtaining export licenses and other trade barriers; and

•

ability to obtain credit and access to capital issues faced by our international customers.

The specific economic conditions in each country will impact our future international sales. For example, a majority of our recognized revenue has been denominated in U.S. dollars. Significant downward fluctuations in currency exchange rates against the U.S. dollar could result in higher product prices and/or declining margins and increased manufacturing costs. If we do not effectively manage the risks associated

with international operations and sales, our business, financial condition and operating results could suffer. In addition, to date we have experienced lower gross margins on sales in certain jurisdictions, particularly China. To the extent that the percentage of our total net sales from China increases and our gross margins do not improve, our business financial condition and operating results could suffer.

The loss of “Normal Trade Relation” status for China, changes in current tariff structures or adoption of other trade policies adverse to China could have an adverse effect on our business.

Manufacturing and retail sales in China are material to our business plan and results of operations. For fiscal years ended December 31, 2004 and 2005, approximately 20% and 30%, of our revenues, respectively, were from sales in China through our KLH subsidiary. In May, 2004, our acquisition of a 64% interest in KLH increased both our manufacturing and retail presence in China.

Our ability to import products from China at current tariff levels could be materially and adversely affected if the “normal trade relations” (“NTR”, formerly “most favored nation”) status the United States government has granted to China for trade and tariff purposes is terminated. As a result of its NTR status, China receives the same favorable tariff treatment that the United States extends to its other “normal” trading partners. China’s NTR status, coupled with its membership in the World Trade Organization, could eventually reduce barriers to manufacturing products in and exporting products from China. However, we cannot provide any assurance that China’s WTO membership or NTR status will not change. As a result of opposition to certain policies of the Chinese government and China’s growing trade surpluses with the United States, there has been, and in the future may be, opposition to NTR status for China. Also, the imposition of trade sanctions by the United States or the European Union against a class of products imported by us from, or the loss of NTR status with, China, could significantly increase our cost of products imported into the United States or Europe and harm our business. Because of the importance of our international sales and international sourcing of manufacturing to our business, our financial condition and results of operations could be significantly and adversely affected if any of the risks described above were to occur.

The government of China may change or even reverse its policies of promoting private industry and foreign investment, in which case our assets and operations may be at risk.

We currently manufacture and sell a significant portion of our components and products in China. Our existing and planned operations in China are subject to the general risks of doing business internationally and the specific risks related to the business, economic and political conditions in China, which include the possibility that the central government of China will change or even reverse its policies of promoting private industry and foreign investment in China. Many of the current reforms which support private business in China are unprecedented or experimental. Other political, economic and social factors, such as political changes, changes in the rates of economic growth, unemployment or inflation, or in the disparities of per capita wealth among citizens of China and between regions within China, could also lead to further readjustment of the government’s reform measures. It is not possible to predict whether the Chinese government will continue to be as supportive of private business in China, nor is it possible to predict how future reforms will affect our business.

Any failure to adequately protect and enforce our intellectual property rights could harm our business.

We regard our intellectual property as critical to our success. We rely on a combination of patent, trademark, copyright, trade secret laws and non-disclosure agreements and confidentiality procedures to protect our proprietary rights. Notwithstanding these laws, we may be unsuccessful in protecting our intellectual property rights or in obtaining patents or registered trademarks for which we apply. Although processes are in place to protect our intellectual property rights, we cannot guarantee that these procedures are adequate to prevent misappropriation of our current technology or that our competitors will not develop technology that is similar to our own.

While there is no single patent or license to technology of material significance to the company, our ability to compete is affected by our ability to protect our intellectual property rights in general. For example, we have a collection of patents related to our photo-ionization detector technology of which the first of such patents expires in 2012, and our ability to compete may be affected by any competing similar or new technology. In addition, if we lose the licensing rights to a patented or other proprietary technology, we may need to stop selling products incorporating that technology and possibly other products, redesign our products or lose a competitive advantage. We cannot ensure that our future patent applications will be approved or that our current patents will not be challenged by third parties. Furthermore, we cannot ensure that, if challenged, our patents will be found to be valid and enforceable.

Any litigation relating to our intellectual property rights could, regardless of the outcome, have a material adverse impact on our business and results of operations.

We might face intellectual property infringement claims that might be costly to resolve and affect our results of operations.

We may, from time to time, be subject to claims of infringement of other parties’ proprietary rights or claims that our own trademarks, patents or other intellectual property rights are invalid. For example, a motion was filed on June 17, 2005, by Polimaster Ltd. and Na & SE Trading Co. Limited, for an injunction that would prevent RAE Systems from shipping its Gamma RAE II product and prohibiting RAE from making any additional sales of products in its possession licensed from Polimaster Ltd. and Na & SE Trading Co. Limited, pending resolution of arbitration between the parties. The motion was denied on September 6, 2005. While this claim may be subject to arbitration in accordance with the original contract between the parties, we do not expect it to have a material effect upon our business or results of operations.

Management will defend itself vigorously, against any claims of this type. However, claims of this type, regardless of merit, can be time-consuming to defend, result in costly litigation, divert management’s attention and resources or require us to enter into royalty or license agreements. The terms of any such license agreements may not be available on reasonable terms, if at all, and the assertion or prosecution of any infringement claims could significantly harm our business.

Some of our products may be subject to product liability claims which could be costly to resolve and affect our results of operations.

There can be no assurance that we will not be subject to third-party claims in connection with our products or that any indemnification or insurance available to us will be adequate to protect us from liability. A product liability claim, product recall or other claim, as well as any claims for uninsured liabilities or in excess of insured liabilities, could have a material adverse effect on our business and results of operations.

We sell a majority of our products through distributors, and if our distributors stop selling our products, our revenues would suffer.

We distribute our products primarily through distributors. We are dependent upon these distributors to sell our products and to assist us in promoting and creating a demand for our products. For example, we derived approximately 59% of our North American revenues from our sales distribution channels in fiscal year 2005. Of that, for the fiscal year ended December 31, 2005, 50 distributors cumulatively accounted for approximately 51% of our total product sales in the United States. We also believe our future growth outside of China depends on the efforts of distributors. In addition, the contractual obligations of our

distributors to continue carrying our products are subject to a sixty-day termination notice by either party for convenience. If one or more of our distributors were to experience financial difficulties or become unwilling to promote and sell our products for any reason, including any refusal to renew their commitment as our distributor, we might not be able to replace such lost revenue, and our business and results of operations could be materially harmed.

Because we purchase a significant portion of our component parts from a limited number of third party suppliers, we are subject to the risk that we may be unable to acquire quality components in a timely manner, which could result in delays of product shipments and damage our business and operating results.

We currently purchase component parts used in the manufacture of our products from a limited number of third party suppliers. We depend on these suppliers to meet our needs for various sensors, microprocessors and other material components. Moreover, we depend on the quality of the products supplied to us over which we have limited control. Should we encounter shortages and delays in obtaining components, we might not be able to supply products in a timely manner due to a lack of components, and our business could be adversely affected.

Future acquisitions that we undertake could be difficult to integrate, disrupt our business, dilute stockholder value or harm our results of operations.

We may acquire or make investments in complementary businesses, technologies, services or products if appropriate opportunities arise. The process of integrating any acquired business, technology, service or product into our business and operations may result in unforeseen operating difficulties and expenditures. Integration of an acquired company also may consume much of our management’s time and attention that would otherwise be available for ongoing development of our business. Moreover, the anticipated benefits of any acquisition may not be realized. Future acquisitions could result in dilutive issuances of equity securities or the incurrence of debt, contingent liabilities or expenses related to goodwill recognition and other intangible assets, any of which could harm our business.

Our ownership interest in Renex will cause us to incur losses that we would not otherwise incur.

We own approximately 36% of Renex Technology Ltd., a wireless systems company still in the research and development stage. We are required to incorporate our share of its expenses as losses in our Consolidated Statements of Operations. If Renex does not begin to generate revenues at the level we anticipate or otherwise incurs greater losses, we could incur greater losses than we anticipate and our results of operations will suffer.

Our business could suffer if we lose the services of any of our executive officers.

Our future success depends to a significant extent on the continued service of our executive officers, including Robert I. Chen, Donald W. Morgan, Peter Hsi, Rudy Mui and Hong Tao Sun. We have no employment agreements with any of these officers. The loss of the services of any of our executive officers could harm our business.

Our officers, directors and principal stockholders beneficially own approximately 35% of our common stock and, accordingly, may exert substantial influence over the company.

Our executive officers and directors and principal stockholders, in the aggregate, beneficially own approximately 35% of our common stock. These stockholders acting together have the ability to substantially influence all matters requiring approval by our stockholders. These matters include the election and removal of the directors, amendment of our certificate of incorporation, and any merger, consolidation or sale of all or substantially all of our assets. In addition, they may dictate the management

of our business and affairs. Furthermore, this concentration of ownership could have the effect of delaying, deferring or preventing a change in control, or impeding a merger or consolidation, takeover or other business combination and may substantially reduce the marketability of our common stock.

Item 4. Controls and Procedures

Changes to Internal Control over Financial Reporting

As previously disclosed in the Company’s annual report on Form 10-K for the fiscal year ending December 31, 2005 under Part II, Item 9A, Controls and Procedures, management identified the following three material weaknesses in the Company’s internal control over financial reporting as of December 31, 2005:

Inadequate number of accounting and finance personnel or consultants sufficiently trained to address some of the complex accounting and financial reporting matters that arise from time-to-time. This control deficiency contributed to the individual material weaknesses described in (ii) and (iii) below, which resulted in audit adjustments to the Company’s 2005 annual consolidated financial statements.

ii.

Inadequate control over our accounting for stock-based compensation under SFAS 123, Accounting for Stock-Based Compensation.

iii.

Inadequate control over our accounting and reporting of certain non-routine transactions occurring at two of our foreign operations. Specifically, we did not identify certain adjustments relating to (a) the valuation of notes payable issued as purchase consideration, (b) deferred tax liabilities associated with certain foreign intangible assets, and (c) the carrying value of our investment in an unconsolidated subsidiary.

During the fourth quarter of 2005 and first quarter of 2006, the Company implemented a number of compensating internal controls and remediation measures to improve the level of assurance regarding the adequacy and accuracy of the Company’s financial information. These compensating internal controls and remediation efforts were as follows:

Controls related to inadequate number of accounting and finance personnel or consultants sufficiently trained to address some of the complex accounting and financial reporting matters that arise from time-to-time:

•

During the fourth quarter of 2005, the Company engaged an outside contractor with state and local tax technical expertise to supplement its current finance staff.

•

During the first quarter of 2006, two additional individuals with technical accounting expertise joined the Company’s finance staff in the U.S. and China.

•

During the first quarter of 2006, the Company engaged a large independent registered public accounting firm to review the Company’s tax compliance under FAS 109, “Accounting for Income Taxes.”

Control over our accounting for stock-based compensation under SFAS 123, Accounting for Stock-Based Compensation:

•

To improve the Company’s controls related to stock-based compensation, management implemented “Equity Edge” during the fourth quarter of 2005, a software program to automate the management and accounting for stock options.

•

During the first quarter of 2006, new automated controls for the management and accounting of stock options were implemented and the resulting database reconciled with the original stock option documents and the diluted share calculation. The “Equity Edge” system was implemented during the first quarter of 2006 and reconciled as of December 31, 2005, and was the system of record for 2005.

Control over our accounting and reporting of certain non-routine transactions occurring at two of our foreign operations:

•

As disclosed in the 2005 annual report on Form 10-K, management identified the steps necessary to remediate the material weakness and was in the process of implementing a number of actions, including the following:

•

document to standards established by senior accounting personnel and the chief financial officer the review, analysis and related conclusions with respect to non-routine transactions;

interview outside accounting consultants to assist on an ongoing basis with the accounting of non-routine transactions;

involve both internal personnel and outside accounting consultants, as needed, early in a non-routine transaction to obtain additional guidance as to the application of generally accepted accounting principles to such a proposed transaction; and

•

requiring senior accounting personnel and the chief financial officer to review non-routine transactions to evaluate and approve the accounting treatment for such transactions.

During the first quarter of 2006, management documented to the Company’s internal control over financial reporting standards established by the chief financial officer and senior accounting personnel for the review, analysis and conclusions with respect to the accounting all future non-routine transactions under generally accepted accounting principles in the Unites States (“GAAP”), including the involvement of both internal accounting personnel and outside accounting consultants, as needed, early in a non-routine transactions to obtain additional guidance as to the application of GAAP.

•

During the first quarter of 2006, but subsequent to the filing of the Company’s 2005 annual report on Form 10-K, management engaged on an ongoing basis a large independent registered public accounting firm to review and advise on the accounting for certain non-routine transactions.

•

During the first quarter of 2006, the Company’s chief financial officer and senior accounting personnel continued to review all non-routine transactions to evaluate and approve the accounting treatment for such transactions.

Except as noted above, there have been no changes in the Company’s internal control over financial reporting during the quarter ended March 31, 2006 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Evaluation of Effectiveness of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, the Company evaluated the effectiveness of its disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The evaluation considered the procedures designed to ensure that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and communicated to our management as appropriate to allow timely decisions regarding required disclosure. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of March 31, 2006 based on the material weaknesses in internal control over financial reporting as identified and discussed above.

Management believes its changes to internal control over financial reporting during the fourth quarter of 2005 and first quarter of 2006 have mitigated the control deficiencies with respect to the preparation of

this quarterly report on Form 10-Q and that these measures have provided reasonable assurance that information required to be disclosed in this report has been recorded, processed, summarized and reported correctly. In particular, the Company’s management believes that the measures implemented to date provide reasonable assurance that the Company’s financial statements included in this report are prepared in accordance with generally accepted accounting principles. Management believes that its controls and procedures will continue to improve as a result of the further implementation of its remediation plan.
